Although there have been documented live births of healthy babies, obtaining an objective diagnosis is crucial to assisting the mother in making an educated decision on what option of management she would like to explore. Prenatal invasive testing is recommended to help obtain an objective diagnosis in cases of abnormal placenta. We present a 23-year-old who, at 14 weeks, had ultrasonographic findings suggestive of placental mesenchymal dysplasia. She was offered prenatal invasive testing but declined and opted for surgical management, with a diagnosis of PMD confirmed on histopathology. There will be occasions such as this when prenatal invasive testing is declined. In these situations, careful consideration can be given to color Doppler and MRI, especially if the patient decides to keep pregnancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=placental%20mesenchymal%20dysplasisa" title="placental mesenchymal dysplasisa">placental mesenchymal dysplasisa</a>, <a href="https://publications.waset.org/abstracts/search?q=molar%20pregnancy" title=" molar pregnancy"> molar pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal%20invasive%20testing" title=" prenatal invasive testing"> prenatal invasive testing</a>, <a href="https://publications.waset.org/abstracts/search?q=Color%20doppler" title=" Color doppler"> Color doppler</a>, <a href="https://publications.waset.org/abstracts/search?q=MRI" title=" MRI"> MRI</a> </p> <a href="https://publications.waset.org/abstracts/189431/placenta-parenchymal-dysplasia-when-to-depend-on-color-doppler-and-mri" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189431.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">23</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Why is the Recurrence Rate of Residual or Recurrent Disease Following Endoscopic Mucosal Resection (EMR) of the Oesophageal Dysplasia’s and T1 Tumours Higher in the Greater Midlands Cancer Network?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harshadkumar%20Rajgor">Harshadkumar Rajgor</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Butterworth"> Jeff Butterworth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Barretts oesophagus increases the risk of developing oesophageal adenocarcinoma. Over the last 40 years, there has been a 6 fold increase in the incidence of oesophageal adenocarcinoma in the western world and the incidence rates are increasing at a greater rate than cancers of the colon, breast and lung. Endoscopic mucosal resection (EMR) is a relatively new technique being used by 2 centres in the greater midlands cancer network. EMR can be used for curative or staging purposes, for high-grade dysplasia’s and T1 tumours of the oesophagus. EMR is also suitable for those who are deemed high risk for oesophagectomy. EMR has a recurrence rate of 21% according to the Wiesbaden data. Method: A retrospective study of prospectively collected data was carried out involving 24 patients who had EMR for curative or staging purposes. Complications of residual or recurrent disease following EMR that required further treatment were investigated. Results: In 54% of cases residual or recurrent disease was suspected. 96% of patients were given clear and concise information regarding their diagnosis of high-grade dysplasia or T1 tumours. All 24 patients consulted the same specialist healthcare team. Conclusion: EMR is a safe and effective treatment for patients who have high-grade dysplasia and T1NO tumours. In 54% of cases residual or recurrent disease was suspected. Initially, only single resections were undertaken. Multiple resections are now being carried out to reduce the risk of recurrence. Complications from EMR remain low in this series and consisted of a single episode of post procedural bleeding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20mucosal%20resection" title="endoscopic mucosal resection">endoscopic mucosal resection</a>, <a href="https://publications.waset.org/abstracts/search?q=oesophageal%20dysplasia" title=" oesophageal dysplasia"> oesophageal dysplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=T1%20tumours" title=" T1 tumours"> T1 tumours</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20network" title=" cancer network"> cancer network</a> </p> <a href="https://publications.waset.org/abstracts/22352/why-is-the-recurrence-rate-of-residual-or-recurrent-disease-following-endoscopic-mucosal-resection-emr-of-the-oesophageal-dysplasias-and-t1-tumours-higher-in-the-greater-midlands-cancer-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Salter Pelvic Osteotomy for the Treatment of Developmental Dysplasia of the Hip: Assessment of Postoperative Results and Risk Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suvorov%20Vasyl">Suvorov Vasyl</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipchuk%20Viktor"> Filipchuk Viktor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: If non-surgical treatment of developmental dysplasia of the hip (DDH) fails or if DDH is late-detected, surgery is necessary. Salter pelvic osteotomy (SPO) is an effective surgical option for such cases. The objectives of this study were to assess the results after SPO, evaluate risk factors, and reveal those radiological parameters that may correlate with the results. Mid- and long-term postoperative results after SPO in 17 patients (22 hip joints) were analyzed. Risk factors included those that do not depend on the surgeon (patient's age, value of the acetabular index (AI) preoperatively, DDH Tonnis grade) and those that depend on the surgeon (amount of AI correction). To radiological parameters which may correlate with the amount of AI correction, we referred distance "d" and the lateral rotation angle. Results: SPO allows performing AI correction in ranges 24.1 ± 6.5°. Excellent and good clinical results were obtained in 95.5% of patients; excellent and good radiological results in 86.4% of patients. Risk factors that do not depend on the surgeon were older patient’s age and higher preoperative AI values (p < 0.05). The risk factor that depends on the surgeon was the amount of AI correction (p < 0.05). The distance "d" was recognized as a radiological parameter that may indicate sufficient AI correction (p < 0.05). Conclusion: In older patients with a higher preoperative AI value, the results will be predictably worse. The surgeon may influence the result with a greater amount of AI correction (which may also be indicated radiologically by the distance "d" values). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developmental%20dysplasia%20of%20the%20hip" title="developmental dysplasia of the hip">developmental dysplasia of the hip</a>, <a href="https://publications.waset.org/abstracts/search?q=results" title=" results"> results</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factor" title=" risk factor"> risk factor</a>, <a href="https://publications.waset.org/abstracts/search?q=pelvic%20osteotomy" title=" pelvic osteotomy"> pelvic osteotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=salter%20osteotomy" title=" salter osteotomy"> salter osteotomy</a> </p> <a href="https://publications.waset.org/abstracts/147537/salter-pelvic-osteotomy-for-the-treatment-of-developmental-dysplasia-of-the-hip-assessment-of-postoperative-results-and-risk-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147537.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Complex Management of Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20A.%20Al%20Qurashi">Abdullah A.

Alaslap</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) is an uncommon, inheritable cardiac disorder characterized by the progressive substitution of cardiac myocytes by fibro-fatty tissues. This pathologic substitution predisposes patients to ventricular arrhythmias and right ventricular failure. The underlying genetic defect predominantly involves genes encoding for desmosome proteins, particularly plakophilin-2 (PKP2). These aberrations lead to impaired cell adhesion, heightening the susceptibility to fibrofatty scarring under conditions of mechanical stress. Primarily, ARVD/C affects the right ventricle, but it can also compromise the left ventricle, potentially leading to biventricular heart failure. Clinical presentations can vary, spanning from asymptomatic individuals to those experiencing palpitations, syncopal episodes, and, in severe instances, sudden cardiac death. The establishment of a diagnostic criterion specifically tailored for ARVD/C significantly aids in its accurate diagnosis. Nevertheless, the task of early diagnosis is complicated by the disease's frequently asymptomatic initial stages, and the overall rarity of ARVD/C cases reported globally. In some cases, as exemplified by the adult female patient in this report, the disease may advance to terminal stages, rendering therapies like Ventricular Tachycardia (VT) ablation ineffective. This case underlines the necessity for increased awareness and understanding of ARVD/C to aid in its early detection and management. Through such efforts, we aim to decrease morbidity and mortality associated with this challenging cardiac disorder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arrhythmogenic%20right%20ventricular%20dysplasia" title="arrhythmogenic right ventricular dysplasia">arrhythmogenic right ventricular dysplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20disease" title=" cardiac disease"> cardiac disease</a>, <a href="https://publications.waset.org/abstracts/search?q=interventional%20cardiology" title=" interventional cardiology"> interventional cardiology</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20electrophysiology" title=" cardiac electrophysiology"> cardiac electrophysiology</a> </p> <a href="https://publications.waset.org/abstracts/175910/complex-management-of-arrhythmogenic-right-ventricular-dysplasiacardiomyopathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175910.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">58</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> The Biomechanical Analysis of Pelvic Osteotomies Applied for Developmental Dysplasia of the Hip Treatment in Pediatric Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suvorov%20Vasyl">Suvorov Vasyl</a>, <a href="https://publications.waset.org/abstracts/search?q=Filipchuk%20Viktor"> Filipchuk Viktor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Developmental Dysplasia of the Hip (DDH) is a frequent pathology in pediatric orthopedist’s practice. Neglected or residual cases of DDH in walking patients are usually treated using pelvic osteotomies. Plastic changes take place in hinge points due to acetabulum reorientation during surgery. Classically described hinge points and a traditional division of pelvic osteotomies on reshaping and reorientation are currently debated. The purpose of this article was to evaluate biomechanical changes during the most commonly used pelvic osteotomies (Salter, Dega, Pemberton) for DDH treatment in pediatric patients. Methods: virtual pelvic models of 2- and 6-years old patients were created, material properties were assigned, pelvic osteotomies were simulated and biomechanical changes were evaluated using finite element analysis (FEA). Results: it was revealed that the patient's age has an impact on pelvic bones and cartilages density (in younger patients the pelvic elements are more pliable - p<0.05). Stress distribution after each of the abovementioned pelvic osteotomy was assessed in 2- and 6-years old patients’ pelvic models; hinge points were evaluated. The new term "restriction point" was introduced, which means a place where restriction of acetabular deformity correction occurs. Pelvic ligaments attachment points were mainly these restriction points. Conclusions: it was found out that there are no purely reshaping and reorientation pelvic osteotomies as previously believed; the pelvic ring acts as a unit in carrying out the applied load. Biomechanical overload of triradiate cartilage during Salter osteotomy in 2-years old patient and in 2- and 6-years old patients during Pemberton osteotomy was revealed; overload of the posterior cortical layer in the greater sciatic notch in 2-years old patient during Dega osteotomy was revealed. Level of Evidence – Level IV, prognostic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developmental%20dysplasia%20of%20the%20hip" title="developmental dysplasia of the hip">developmental dysplasia of the hip</a>, <a href="https://publications.waset.org/abstracts/search?q=pelvic%20osteotomy" title=" pelvic osteotomy"> pelvic osteotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hinge%20point" title=" hinge point"> hinge point</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a> </p> <a href="https://publications.waset.org/abstracts/150398/the-biomechanical-analysis-of-pelvic-osteotomies-applied-for-developmental-dysplasia-of-the-hip-treatment-in-pediatric-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150398.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Bcl-2: A Molecule to Detect Oral Cancer and Precancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vandana%20Singh">Vandana Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Subash%20Singh"> Subash Singh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Oral squamous cell carcinoma is the most common malignant tumor of the oral cavity. Normally the death of cell and the growth are active processes and depend not only on external factors but also on the expression of genes like Bcl-2, which activate and inhibit apoptosis. The term Bcl-2 is an acronym for B-cell lymphoma/ leukemia -2 genes. Objectives: An attempt was made to evaluate Bcl-2 oncoprotein expression in patients with oral precancer and cancer and to assess possible correlation between Bcl-2 oncoprotein expression and clinicopathological features of oral precancer and cancer. Material and Methods: This is a selective prospective clinical and immunohistochemical study. Clinicopathological examination is correlated with immunohistochemical findings. The immunolocalization of Bcl-2 protein is performed using the labeled streptavidin biotin (LSAB) method. To visualize the reaction, 3, 3-diaminobenzidine (DAB) is used. Results: Bcl-2 expression was positive in 11 [36.66 %, low Bcl-2 expression 3 (10.00 %), moderate Bcl-2 expression 7 (23.33 %), and high Bcl-2 expression 1 (3.33 %)] oral cancer cases and in 14 [87.50 %, low expression 8 (50 %), moderate expression 6 (37.50 %)] precancer cases. Conclusion: On the basis of the results of our study we conclude that positive Bcl-2 expression may be an indicator of poor prognosis in oral cancer and precancer. Relevance: It has been reported that there is deregulation of Bcl-2 expression during progression from oral epithelial dysplasia to squamous cell carcinoma. It can be used for revealing progression of epithelial dysplasia to malignancy and as a prognostic marker in oral precancer and cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BcL-2" title="BcL-2">BcL-2</a>, <a href="https://publications.waset.org/abstracts/search?q=immunohistochemistry" title=" immunohistochemistry"> immunohistochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20cancer" title=" oral cancer"> oral cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20precancer" title=" oral precancer"> oral precancer</a> </p> <a href="https://publications.waset.org/abstracts/79418/bcl-2-a-molecule-to-detect-oral-cancer-and-precancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79418.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Adolescent and Adult Hip Dysplasia on Plain Radiographs.

Different measurements of normal and dysplastic hip joints in 45 patients were analyzed. Attempt was made to establish reproducible, easy applicable in practice approach for evaluation and follow up of patients with hip dysplasia. The youngest of our patients was 11 years and the oldest was 47 years. Only one of our patients needed conversion to total hip replacement (THR) during ten years of follow-up. It was emphasized that selected set of measurements was built for purpose to serve, especially those who’s scheduled or undergone PAO. This approach was based on concept of acetabulum-femoral head complex and importance of reliable reference points of measurements. Comparative analysis of measured parameters between normal and dysplastic hips was performed. Among 10 selected parameters, we use already well established such as lateral center edge angle and head extrusion index, but to serve specific group of patients with PAO, new parameters were considered such as complex lateralization and complex proximal migration. By our opinion proposed approach is easy applicable in busy clinical practice, satisfactorily delineate hip pathology and give to surgeon who’s going to perform PAO guidelines in condensed form. It is also useful tools for postoperative follow up after PAO. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=periacetabular%20osteotomy" title="periacetabular osteotomy">periacetabular osteotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=plain%20radiograph%E2%80%99s%20measurements" title=" plain radiograph’s measurements"> plain radiograph’s measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=adult" title=" adult"> adult</a> </p> <a href="https://publications.waset.org/abstracts/174144/adolescent-and-adult-hip-dysplasia-on-plain-radiographs-analysis-of-measurements-and-attempt-for-optimization-of-diagnostic-and-performance-approaches-for-patients-with-periacetabular-osteotomy-pao" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174144.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> The Importance of Clinicopathological Features for Differentiation Between Crohn's Disease and Ulcerative Colitis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20E.%20Esheba">Ghada E.

Despite their distinct natures, these two diseases share many similar etiologic, clinical and pathological features, as a result, their accurate differential diagnosis may sometimes be difficult. Correct diagnosis is important because surgical treatment and long-term prognosis differ from UC and CD. Aim: This study aims to study the characteristic clinicopathological features which help in the differential diagnosis between UC and CD, and assess the disease activity in ulcerative colitis. Materials and methods: This study was carried out on 50 selected cases. The cases included 27 cases of UC and 23 cases of CD. All the cases were examined using H& E and immunohistochemically for bcl-2 expression. Results: Characteristic features of UC include: decrease in mucous content, irregular or villous surface, crypt distortion, and cryptitis, whereas the main cardinal histopathological features seen in CD were: epitheloid granuloma, transmural chronic inflammation, absence of mucin depletion, irregular surface, or crypt distortion. 3 cases of UC were found to be associated with dysplasia. UC mucosa contains fewer Bcl-2+ cells compared with CD mucosa. Conclusion: This study using multiple parameters such clinicopathological features and Bcl-2 expression as studied by immunohistochemical stain, helped to gain an accurate differentiation between UC and CD. Furthermore, this work spotted the light on the activity and different grades of UC which could be important for the prediction of relapse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Crohn%27s%20disease" title="Crohn's disease">Crohn's disease</a>, <a href="https://publications.waset.org/abstracts/search?q=dysplasia" title=" dysplasia"> dysplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20disease" title=" inflammatory bowel disease"> inflammatory bowel disease</a>, <a href="https://publications.waset.org/abstracts/search?q=ulcerative%20colitis" title=" ulcerative colitis"> ulcerative colitis</a> </p> <a href="https://publications.waset.org/abstracts/59178/the-importance-of-clinicopathological-features-for-differentiation-between-crohns-disease-and-ulcerative-colitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59178.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Expression of CASK Antibody in Non-Mucionus Colorectal Adenocarcinoma and Its Relation to Clinicopathological Prognostic Factors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reham%20H.%20Soliman">Reham H.

CASK has been linked as a good prognostic factor with some tumor subtypes, while considered as a poor prognostic marker in others. To our knowledge, no sufficient evidence of CASK role in colorectal cancer is available. The aim of this study is to evaluate the expression of Calcium/calmodulin-dependent serine protein kinase (CASK) in non-mucinous colorectal adenocarcinoma and adenomatous polyps as precursor lesions and assess its prognostic significance. The study included 42 cases of conventional colorectal adenocarcinoma and 15 biopsies of adenomatous polyps with variable degrees of dysplasia. They were reviewed for clinicopathological prognostic factors and stained by CASK; mouse, monoclonal antibody using heat-induced antigen retrieval immunohistochemical techniques. The results showed that CASK protein was significantly overexpressed (p <0.05) in CRC compared with adenoma samples. The CASK protein was overexpressed in the majority of CRC samples with 85.7% of cases showing moderate to strong expression, while 46.7% of adenomas were positive. CASK overexpression was significantly correlated with both TNM stage and grade of differentiation (p <0.05). There was a significantly higher expression in tumor samples with early stages (I/II) rather than advanced stage (III/IV) and with low grade (59.5%) rather than high grade (40.5%). Another interesting finding was found among the adenomas group, where the stronger intensity of staining was observed in samples with high grade dysplasia (33.3%) than those of lower grades (13.3%). In conclusion, this study shows that there is significant overexpression of CASK protein in CRC as well as in adenomas with high grade dysplasia. This indicates that CASK is involved in the process of carcinogenesis and functions as a potential trigger of the adenoma-carcinoma cascade. CASK was significantly overexpressed in early stage and low-grade tumors rather than tumors with advanced stage and higher histological grades. This suggests that CASK protein is a good prognostic factor. We suggest that CASK affects CRC in two different ways derived from its physiology. CASK as part of MAGUK family can stimulate proliferation and through its cell membrane localization and as a mediator of cell-cell adhesion might contribute in tumor confinement and localization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CASK" title="CASK">CASK</a>, <a href="https://publications.waset.org/abstracts/search?q=colorectal%20cancer" title=" colorectal cancer"> colorectal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=overexpression" title=" overexpression"> overexpression</a>, <a href="https://publications.waset.org/abstracts/search?q=prognosis" title=" prognosis"> prognosis</a> </p> <a href="https://publications.waset.org/abstracts/58771/expression-of-cask-antibody-in-non-mucionus-colorectal-adenocarcinoma-and-its-relation-to-clinicopathological-prognostic-factors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">279</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Complex Management of Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Almehmadi">Fahad Almehmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Alrajhi"> Abdullah Alrajhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bader%20K.%20Alaslab"> Bader K.

Hassani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) is an uncommon, inheritable cardiac disorder characterized by the progressive substitution of cardiac myocytes by fibro-fatty tissues. This pathologic substitution predisposes patients to ventricular arrhythmias and right ventricular failure. The underlying genetic defect predominantly involves genes encoding for desmosome proteins, particularly plakophilin-2 (PKP2). These aberrations lead to impaired cell adhesion, heightening the susceptibility to fibrofatty scarring under conditions of mechanical stress. Primarily, ARVD/C affects the right ventricle, but it can also compromise the left ventricle, potentially leading to biventricular heart failure. Clinical presentations can vary, spanning from asymptomatic individuals to those experiencing palpitations, syncopal episodes, and, in severe instances, sudden cardiac death. The establishment of a diagnostic criterion specifically tailored for ARVD/C significantly aids in its accurate diagnosis. Nevertheless, the task of early diagnosis is complicated by the disease's frequently asymptomatic initial stages, and the overall rarity of ARVD/C cases reported globally. In some cases, as exemplified by the adult female patient in this report, the disease may advance to terminal stages, rendering therapies like Ventricular Tachycardia (VT) ablation ineffective. This case underlines the necessity for increased awareness and understanding of ARVD/C to aid in its early detection and management. Through such efforts, we aim to decrease morbidity and mortality associated with this challenging cardiac disorder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARVD%2FC" title="ARVD/C">ARVD/C</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiology" title=" cardiology"> cardiology</a>, <a href="https://publications.waset.org/abstracts/search?q=interventional%20cardiology" title=" interventional cardiology"> interventional cardiology</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20electrophysiology" title=" cardiac electrophysiology"> cardiac electrophysiology</a> </p> <a href="https://publications.waset.org/abstracts/175931/complex-management-of-arrhythmogenic-right-ventricular-dysplasiacardiomyopathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175931.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">63</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> MRI Findings in Children with Intrac Table Epilepsy Compared to Children with Medical Responsive Epilepsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Susan%20Amirsalari">Susan Amirsalari</a>, <a href="https://publications.waset.org/abstracts/search?q=Azime%20Khosrinejad"> Azime Khosrinejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Rahimian"> Elham Rahimian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Epilepsy is a common brain disorder characterized by a persistent tendency to develop in neurological, cognitive, and psychological contents. Magnetic Resonance Imaging (MRI) is a neuroimaging test facilitating the detection of structural epileptogenic lesions. This study aimed to compare the MRI findings between patients with intractable and drug-responsive epilepsy. Material & methods: This case-control study was conducted from 2007 to 2019. The research population encompassed all 1-16- year-old patients with intractable epilepsy referred to the Shafa Neuroscience Center (n=72) (a case group) and drug-responsive patients referred to the pediatric neurology clinic of Baqiyatallah Hospital (a control group). Results: There were 72 (23.5%) patients in the intractable epilepsy group and 200 (76.5%) patients in the drug-responsive group. The participants' mean age was 6.70 ±4.13 years, and there were 126 males and 106 females in this study Normal brain MRI was noticed in 21 (29.16%) patients in the case group and 184 (92.46%) patients in the control group. Neuronal migration disorder (NMD)was also exhibited in 7 (9.72%) patients in the case group and no patient in the control group. There were hippocampal abnormalities and focal lesions (mass, dysplasia, etc.) in 10 (13.88%) patients in the case group and only 1 (0.05%) patient in the control group. Gliosis and porencephalic cysts were presented in 3 (4.16%) patients in the case group and no patient in the control group. Cerebral and cerebellar atrophy was revealed in 8 (11.11%) patients in the case group and 4 (2.01%) patients in the control group. Corpus callosum agenesis, hydrocephalus, brain malacia, and developmental cyst were more frequent in the case group; however, the difference between the groups was not significant. Conclusion: The MRI findings such as hippocampal abnormalities, focal lesions (mass, dysplasia), NMD, porencephalic cysts, gliosis, and atrophy are significantly more frequent in children with intractable epilepsy than in those with drug-responsive epilepsy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20resonance%20imaging" title="magnetic resonance imaging">magnetic resonance imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=intractable%20epilepsy" title=" intractable epilepsy"> intractable epilepsy</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20responsive%20epilepsy" title=" drug responsive epilepsy"> drug responsive epilepsy</a>, <a href="https://publications.waset.org/abstracts/search?q=neuronal%20migrational%20disorder" title=" neuronal migrational disorder"> neuronal migrational disorder</a> </p> <a href="https://publications.waset.org/abstracts/185141/mri-findings-in-children-with-intrac-table-epilepsy-compared-to-children-with-medical-responsive-epilepsy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185141.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">45</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Esophageal Premalignant and Malignant Epithelial Lesions: Pathological Characteristics and Value of Cyclooxygenase-2 Expression. </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Mohamed%20Abd%20Elmoneim">Hanan Mohamed Abd Elmoneim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rawan%20Saleh%20AlJawi"> Rawan Saleh AlJawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Razan%20Saleh%20AlJawi"> Razan Saleh AlJawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aseel%20Abdullah%20AlMasoudi"> Aseel Abdullah AlMasoudi </a>, <a href="https://publications.waset.org/abstracts/search?q=Zyad%20Adnan%20Turkistani"> Zyad Adnan Turkistani</a>, <a href="https://publications.waset.org/abstracts/search?q=Anas%20Abdulkarim%20Alkhoutani"> Anas Abdulkarim Alkhoutani </a>, <a href="https://publications.waset.org/abstracts/search?q=Ohood%20Musaed%20AlJuhani"> Ohood Musaed AlJuhani </a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Attiyah%20AlZahrani"> Hanan Attiyah AlZahrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background Esophageal cancer is the eighth most common cancer worldwide. More than 90% of esophageal cancers are either squamous cell carcinoma or adenocarcinoma. Squamous dysplasia is a precancerous lesion for squamous cell carcinoma and Barrett's esophagus is the precancerous lesion for adenocarcinoma. Gastro-esophageal reflux disease (GERD) is the initiation factor for Barrett's esophagus. Cyclooxygenase-2 (COX-2) is a key enzyme in arachidonic metabolism. It appears to play an important role in gastrointestinal carcinogenesis. COX-2 activity may be a potential target for the prevention of cancer progression by selective COX-2 inhibitors, which decrease proliferation and increase apoptosis. Objectives To assess COX-2 expression in premalignant and malignant esophageal epitheliums changes and detect its roles in progression of these lesions. Materials and Methods We analyzed the expression of COX-2 immunohistochemically in 40 esophageal biopsies utilizing the streptavidin-biotin-peroxidase complex method on archival formalin fixed-paraffin embedded blocks. Histopathologically, 17 (42.5%) of cases were non-malignant cases which included GERD, Barrett's esophagus and squamous dysplasia. The malignant cases were 23 (57.5%) squamous cell carcinoma, adenocarcinoma and undifferentiated carcinoma. Results In non-malignant cases 7 (41.2%) out of 17 cases had high COX-2 expression. In squamous cell carcinoma 10 (83.3%) out of 12 cases had high COX-2 expression. The expression of COX-2 was high in all 9 (100%) cases of adenocarcinoma. COX-2 expression is significantly increased (P=0.005 and P=0.0001) in squamous cell carcinoma and adenocarcinoma respectively. There was a significant difference in COX-2 immunoreactivity between malignant and non-malignant lesions (P=0.0003). Conclusion COX-2 is responsible for the progression of esophageal diseases from benign to malignant. We recommend that COX-2 immunohistochemistry should be done routinely for premalignant and malignant esophageal lesions as selective COX-2 inhibitors will be helpful in the treatment. Further studies on molecular and genetic basis of COX-2 expression are needed to unmask its role and relation to progression of esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cox-2" title="Cox-2">Cox-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20adinocarcinoma" title=" Esophageal adinocarcinoma"> Esophageal adinocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20squamous%20cell%20carcinoma" title=" Esophageal squamous cell carcinoma"> Esophageal squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunohistochemistry." title=" Immunohistochemistry.

This study assessed and described the congenital malformations in newborn dogs. The study included litters attend in the São Paulo State University (UNESP) Veterinary Hospital, Botucatu, Sao Paulo, Brazil. One hundred seventy-eight litters and 803 newborns were evaluated. The occurrence of litters with malformations was 24.7%, and of newborns was 6.7%. Twenty-seven different malformations were registered: anasarca, anal atresia, cleft lip, cleft palate, duplicated right ribcage, equinovarus, exencephaly, gastroschisis, hydrocephaly, lissencephaly, macroglossia, microphthalmia, mitral valve dysplasia, omphalocele, eyelid agenesis, persistent urachus, polydactyly, pulmonary hypoplasia, pulmonary valve stenosis, rectovaginal fistula, agenesis of abdominal muscles, rib hypoplasia, scoliosis, segmental aplasia of the intestines, tricuspid valve dysplasia, unilateral kidney agenesis, and vaginal atresia. 68.7% of newborns died as a result of malformations. The pure breeds with the highest chances of manifesting malformations in contrast with mixed breeds were French Bulldog, Pug, English Bulldog, Rottweiler, German Spitz, Pinscher, Pitbull, Yorkshire Terrier, and Shih-Tzu. Significant values (P<0.05) occurred in races French Bulldogs and Pugs. The causes of congenital disabilities are possibly related to hereditary genetic factors considering that the highest incidence of malformations was observed among purebreds. There as one case of exposure to a teratogenic agent, but no other mothers were exposed to such agents during pregnancy. Two cases of consanguineal breeding between siblings were reported. The mortality rate was high. Genetic breeding programs for reproduction, avoiding consanguineous mating, care in choosing parents, and avoiding maternal exposure to teratogenic agents are of utmost importance in reducing dog malformations and consequent mortality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congenital%20defects" title="congenital defects">congenital defects</a>, <a href="https://publications.waset.org/abstracts/search?q=teratogenesis" title=" teratogenesis"> teratogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=canine%20neonatology" title=" canine neonatology"> canine neonatology</a>, <a href="https://publications.waset.org/abstracts/search?q=newborn%20puppy" title=" newborn puppy"> newborn puppy</a> </p> <a href="https://publications.waset.org/abstracts/117938/congenital-malformations-in-neonate-dogs-in-the-sao-paulo-state-university-veterinary-hospital-botucatu-sao-paulo-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117938.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Impact of Helicobacter pylori Infection on Colorectal Adenoma-Colorectal Carcinoma Sequence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jannis%20Kountouras">Jannis Kountouras</a>, <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Kapetanakis"> Nikolaos Kapetanakis</a>, <a href="https://publications.waset.org/abstracts/search?q=Stergios%20A.%20Polyzos"> Stergios A.

We aimed to investigate the possible involvement of active Hp-I in the sequence: chronic inflammation–adenoma–colorectal cancer (CRC) development. Methods: Four pillars were investigated: (i) endoscopic and conventional histological examinations of patients with CRC, colorectal adenomas (CRA) versus controls to detect the presence of active Hp-I; (ii) immunohistochemical determination of the presence of Hp; expression of CD44, an indicator of CSCs and/or bone marrow-derived stem cells (BMDSCs); expressions of oncogene Ki67 and anti-apoptotic Bcl-2 protein; (iii) expression of CD45, indicator of immune surveillance locally (assessing mainly T and B lymphocytes locally); and (iv) correlation of the studied parameters with the presence or absence of Hp-I. Results: Among 50 patients with CRC, 25 with CRA, and 10 controls, a significantly higher presence of Hp-I in the CRA (68%) and CRC group (84%) were found compared with controls (30%). The presence of Hp-I with accompanying immunohistochemical expression of CD44 in biopsy specimens was revealed in a high proportion of patients with CRA associated with moderate/severe dysplasia (88%) and CRC patients with moderate/severe degree of malignancy (91%). Comparable results were also obtained for Ki67, Bcl-2, and CD45 immunohistochemical expressions. Concluding Remarks: Hp-I seems to be involved in the sequence: CRA – dysplasia – CRC, similarly to the upper GI tract oncogenesis, by several pathways such as the following: Beyond Hp-I associated insulin resistance, the major underlying mechanism responsible for the metabolic syndrome (MetS) that increase the risk of colorectal neoplasms, as implied by other Hp-I related MetS pathologies, such as non-alcoholic fatty liver disease and upper GI cancer, the disturbance of the normal GI microbiota (i.e., dysbiosis) and the formation of an irritative biofilm could contribute to a perpetual inflammatory upper GIT and colon mucosal damage, stimulating CSCs or recruiting BMDSCs and affecting oncogenes and immune surveillance processes. Further large-scale relative studies with a pathophysiological perspective are necessary to demonstrate in-depth this relationship. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helicobacter%20pylori" title="Helicobacter pylori">Helicobacter pylori</a>, <a href="https://publications.waset.org/abstracts/search?q=colorectal%20cancer" title=" colorectal cancer"> colorectal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=colorectal%20adenomas" title=" colorectal adenomas"> colorectal adenomas</a>, <a href="https://publications.waset.org/abstracts/search?q=gastrointestinal%20oncogenesis" title=" gastrointestinal oncogenesis"> gastrointestinal oncogenesis</a> </p> <a href="https://publications.waset.org/abstracts/128513/impact-of-helicobacter-pylori-infection-on-colorectal-adenoma-colorectal-carcinoma-sequence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128513.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Operative Technique of Glenoid Anteversion Osteotomy and Soft Tissue Rebalancing for Brachial Plexus Birth Palsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Zaidman">Michael Zaidman</a>, <a href="https://publications.waset.org/abstracts/search?q=Naum%20Simanovsky"> Naum Simanovsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most of brachial birth palsies are transient.

Anteversion glenoid osteotomy with latissimus dorsi and teres major tendon transfers could be an alternative procedure of proximal humeral external rotation osteotomy for patients with severe glenohumeral dysplasia secondary to brachial plexus birth palsy. We will discuss pre-operative planning and stepped operative technique of the procedure on clinical example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obstetric%20brachial%20plexus%20palsy" title="obstetric brachial plexus palsy">obstetric brachial plexus palsy</a>, <a href="https://publications.waset.org/abstracts/search?q=glenoid%20anteversion%20osteotomy" title=" glenoid anteversion osteotomy"> glenoid anteversion osteotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=tendon%20transfer" title=" tendon transfer"> tendon transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=operative%20technique" title=" operative technique"> operative technique</a> </p> <a href="https://publications.waset.org/abstracts/174911/operative-technique-of-glenoid-anteversion-osteotomy-and-soft-tissue-rebalancing-for-brachial-plexus-birth-palsy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">74</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Evaluation of P16, Human Papillomavirus Capsid Protein L1 and Ki67 in Cervical Intraepithelial Lesions: Potential Utility in Diagnosis and Prognosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Alsaeid%20Alshenawy">Hanan Alsaeid Alshenawy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cervical dysplasia, which is potentially precancerous, has increased in young women. Detection of cervical is important for reducing morbidity and mortality in cervical cancer. This study analyzes the immunohistochemical expression of p16, HPV L1 capsid protein and Ki67 in cervical intraepithelial lesions and correlates them with lesion grade to develop a set of markers for diagnosis and detect the prognosis of cervical cancer precursors. Methods: 75 specimens were analyzed including 15 cases CIN 1, 28 CIN 2, 20 CIN 3, and 12 cervical squamous carcinoma, besides 10 normal cervical tissues. They were stained for p16, HPV L1 and Ki-67. Sensitivity, specificity, predictive values and accuracy were evaluated for each marker. Results: p16 expression increased during the progression from CIN 1 to carcinoma. HPV L1 positivity was detected in CIN 2 and decreased gradually as the CIN grade increased but disappear in carcinoma. Strong Ki-67 expression was observed with high grades CIN and carcinoma. p16, HPV L1 and Ki67 were sensitive but with variable specificity in detecting CIN lesions. Conclusions: p16, HPV L1 and Ki67 are useful set of markers in establishing the risk of high-grade CIN. They complete each other to reach accurate diagnosis and prognosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=p16" title="p16">p16</a>, <a href="https://publications.waset.org/abstracts/search?q=HPV%20L1" title=" HPV L1"> HPV L1</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki67" title=" Ki67"> Ki67</a>, <a href="https://publications.waset.org/abstracts/search?q=CIN" title=" CIN"> CIN</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20carcinoma" title=" cervical carcinoma"> cervical carcinoma</a> </p> <a href="https://publications.waset.org/abstracts/19766/evaluation-of-p16-human-papillomavirus-capsid-protein-l1-and-ki67-in-cervical-intraepithelial-lesions-potential-utility-in-diagnosis-and-prognosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19766.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Investigation of Possible Precancerous Viral Markers in Dental Follicles of Asymptomatic Impacted Teeth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serap%20Keskin%20Tun%C3%A7">Serap Keskin Tunç</a>, <a href="https://publications.waset.org/abstracts/search?q=Cennet%20Neslihan%20Ero%C4%9Flu"> Cennet Neslihan Eroğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevin%C3%A7%20%C5%9Eahin"> Sevinç Şahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Selda%20Se%C3%A7kin"> Selda Seçkin </a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been suggested that various viruses may play a role in the pathogenesis of cancerous oral lesions in the literature. The aim of this study was to investigate the presence of both possible precancerous viral markers (HPV, HHV8, HSV1, HSV2, and EBV), and p53 and Ki-67 in the dental follicles of asymptomatic impacted teeth. A hundred healthy volunteers, older than 18 years old, included in the study. Dental follicles of extracted impacted teeth were excised and fixated in 10% formaldehyde. Histopathological and immunohistochemical examinations using HPV (containing HPV 8 and HPV 11), p16 (containing HPV 16), HHV8, HSV1, HSV2, EBV, p53 and Ki-67 antibodies were carried out. Also, the immunohistochemical results were correlated with the clinicopathological feature by Chi-square test statistically No dysplasia or neoplasm was observed. 62% of the cases were positive for p16, 32% were positive for EBV, 26% were positive for HSV1, immunohistochemically. All cases were immunonegative for HPV, HSV2, and HHV8. There was statistically significant correlation between overexpression of p53 with both EBV and p16 positivity (p<0.05). Direct correlation between higher expression of Ki-67 between EBV immunopositivity was detected (p<0.05). Thus, these viruses may be suggested to show trophism to the dental follicles acting as a reservoir. In conclusion, all dental follicles of extracted impacted teeth should be examined histopathologically in order to detect and prevent possible viral oncogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dental%20follicles" title="dental follicles">dental follicles</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki67" title=" Ki67"> Ki67</a>, <a href="https://publications.waset.org/abstracts/search?q=p53" title=" p53"> p53</a>, <a href="https://publications.waset.org/abstracts/search?q=precancerous%20markers%20viral%20markers" title=" precancerous markers viral markers"> precancerous markers viral markers</a> </p> <a href="https://publications.waset.org/abstracts/31991/investigation-of-possible-precancerous-viral-markers-in-dental-follicles-of-asymptomatic-impacted-teeth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31991.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Sequence Analysis of the Effect of HPV-16 E1 Variation on Cervical Carcinogenesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fern%20Baedyananda">Fern Baedyananda</a>, <a href="https://publications.waset.org/abstracts/search?q=Arkom%20Chaiwongkot"> Arkom Chaiwongkot</a>, <a href="https://publications.waset.org/abstracts/search?q=Somchai%20Niruthisard"> Somchai Niruthisard</a>, <a href="https://publications.waset.org/abstracts/search?q=Nakarin%20Kitkumthorn"> Nakarin Kitkumthorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Parvapan%20Bhattarakosol"> Parvapan Bhattarakosol</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-risk human papillomavirus (HPV) infections cause transformation of the host cells by down-regulating and inhibiting host regulatory proteins such as p53 and pRb by overexpressing the viral oncoproteins E6 and E7. However, the E1 protein which is the only enzyme encoded by HPV has also been shown to cause DNA instability leading to the integration of the virus into the host genome and triggering carcinogenic events. A 63bp duplication in the E1 helicase region has been detected in European patients. However, the clinical prognosis of these patients is still controversial. This study was performed to determine the presence of the HPV-16 E1 63bp duplication in patient cervical samples in Thai women and determine the sequence of the variant in the Thai population. Detection of the HPV-16 E1 duplication in the helicase region was performed in 90 patient cell samples across normal, cervical intraepithelial neoplasia I-III, and squamous cervical carcinoma stages by PCR. The PCR products were purified and sequenced to determine the presence of duplication variants.The variant form was found in 10% of all CIN 1 patients. In this study, the presence of the 63 bp duplication variant in the Thai population was found to be present and was further characterized. Interestingly, all samples that exhibited the variant form of HPV-16 E1 were classified as CIN I. Presence of the variant, constricted to mild dysplasia signifies the importance of HPV-16 E1 in carcinogenesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carcinogenesis" title="carcinogenesis">carcinogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer" title=" cervical cancer"> cervical cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20papillomavirus" title=" human papillomavirus"> human papillomavirus</a>, <a href="https://publications.waset.org/abstracts/search?q=HPV-16%20E1" title=" HPV-16 E1"> HPV-16 E1</a> </p> <a href="https://publications.waset.org/abstracts/63911/sequence-analysis-of-the-effect-of-hpv-16-e1-variation-on-cervical-carcinogenesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63911.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">236</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Prevalence of High Risk Human Papillomavirus in Cervical Dysplasia and Cancer Samples from Twin Cities in Pakistan </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sana%20Gul">Sana Gul</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheeba%20Murad"> Sheeba Murad</a>, <a href="https://publications.waset.org/abstracts/search?q=Aneela%20Javed"> Aneela Javed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Human Papilloma Virus (HPV) is small DNA virus mostly infecting mucosa and cutaneous keratinocytes. So far, more than 200 Human papillomaviruses are known. HPV have been divided into high- and low-risk on the basis of their oncogenic potential. High risk HPV is considered to be the main etiological cause for cervical cancer. Objective: Current study was designed to screen the local cervical cancer patients from the twin cities of Pakistan for the occurance of high risk HPV. Methodology: A total of 67 formalin fixed paraffin-embedded samples of cervical cancer biopsies were obtained from the government hospitals in Islamabad and Rawalpindi. Cervical cancer biopsies were examined for the presence of HPV DNA. Polymerase chain reaction (PCR) was used for the amplification of a region in the HPV-L1 gene for the general detection of the Papilloma virus and for the genotype specific detection of high risk HPV 16 and 18 using the GP5/GP6 primers and genotype specific primers respectively. Results: HPV DNA was detected in 59 out of 67 samples analyzed. 30 samples showed the presence of HPV16 while 22 samples were positive for HPV 18 . HPV subtype could not be determined in 7 samples. Conclusion: Our results show a strong association between HPV infection and cervical cancer among women in twin cities of Pakistan. One way to minimize the disease burden in relation to HPV infection in Pakistani population is the use of prophylactic vaccines and routine screening. An early diagnosis of HPV infection will allow better health management to reduce the risk of developing cervical cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer" title="cervical cancer">cervical cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20papillomavirus" title=" human papillomavirus"> human papillomavirus</a>, <a href="https://publications.waset.org/abstracts/search?q=HPV%2016" title=" HPV 16"> HPV 16</a> </p> <a href="https://publications.waset.org/abstracts/43081/prevalence-of-high-risk-human-papillomavirus-in-cervical-dysplasia-and-cancer-samples-from-twin-cities-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43081.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> The Identification of Combined Genomic Expressions as a Diagnostic Factor for Oral Squamous Cell Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ki-Yeo%20Kim">Ki-Yeo Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Trends in genetics are transforming in order to identify differential coexpressions of correlated gene expression rather than the significant individual gene. Moreover, it is known that a combined biomarker pattern improves the discrimination of a specific cancer. The identification of the combined biomarker is also necessary for the early detection of invasive oral squamous cell carcinoma (OSCC). To identify the combined biomarker that could improve the discrimination of OSCC, we explored an appropriate number of genes in a combined gene set in order to attain the highest level of accuracy. After detecting a significant gene set, including the pre-defined number of genes, a combined expression was identified using the weights of genes in a gene set. We used the Principal Component Analysis (PCA) for the weight calculation. In this process, we used three public microarray datasets. One dataset was used for identifying the combined biomarker, and the other two datasets were used for validation. The discrimination accuracy was measured by the out-of-bag (OOB) error. There was no relation between the significance and the discrimination accuracy in each individual gene. The identified gene set included both significant and insignificant genes. One of the most significant gene sets in the classification of normal and OSCC included MMP1, SOCS3 and ACOX1. Furthermore, in the case of oral dysplasia and OSCC discrimination, two combined biomarkers were identified. The combined genomic expression achieved better performance in the discrimination of different conditions than in a single significant gene. Therefore, it could be expected that accurate diagnosis for cancer could be possible with a combined biomarker. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oral%20squamous%20cell%20carcinoma" title="oral squamous cell carcinoma">oral squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20biomarker" title=" combined biomarker"> combined biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=microarray%20dataset" title=" microarray dataset"> microarray dataset</a>, <a href="https://publications.waset.org/abstracts/search?q=correlated%20genes" title=" correlated genes"> correlated genes</a> </p> <a href="https://publications.waset.org/abstracts/35990/the-identification-of-combined-genomic-expressions-as-a-diagnostic-factor-for-oral-squamous-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35990.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">423</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Prevalence of Human Papillomavirus in Squamous Intraepithelial Lesions and Cervical Cancer in Women of the North of Chihuahua, Mexico</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estefania%20Ponce-Amaya">Estefania Ponce-Amaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Lidia%20Arellano-Ortiz"> Ana Lidia Arellano-Ortiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Diaz-Hernandez"> Cecilia Diaz-Hernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Alberto%20Lopez-Diaz"> Jose Alberto Lopez-Diaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20De%20La%20Mora-Covarrubias"> Antonio De La Mora-Covarrubias</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Lucia%20Vargas-Requena"> Claudia Lucia Vargas-Requena</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Salcedo-Vargas"> Mauricio Salcedo-Vargas</a>, <a href="https://publications.waset.org/abstracts/search?q=Florinda%20Jimenez-Vega"> Florinda Jimenez-Vega </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cervical Cancer (CC) is the second leading cause of death among women worldwide and it had been associated with a persistent infection of human papillomavirus (HPV). The goal of the current study was to identify the prevalence of HPV infection in women with abnormal Pap smear who were attended at Dysplasia Clinic of Ciudad Juarez, Mexico. Methods: Cervical samples from 146 patients, who attended the Colposcopy Clinic at Sanitary Jurisdiction II of Cd Juarez, were collected for histopathology and molecular study. DNA was isolated for the HPV detection by Polymerase Chain Reaction (PCR) using MY09/011 and GP5/6 primers. The associated risk factors were assessed by a questionnaire. The statistical analysis was performed by ANOVA, using EpiINFO V7 software. Results: HPV infection was present in 142 patients (97.3 %). The prevalence of HPV infection was distributed in a 96% of all evaluated groups, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HISIL) and CC. We found a statistical significance (α = <0.05) between gestation and number of births as risk factors. The median values showed an ascending tend according with the lesion progression. However, CC showed a statistically significant difference with respect to the pre-carcinogenic stages. Conclusions: In these Mexican patients exists a high prevalence of HPV infection, and for that reason, we are studying the most prevalent HPV genotypes in this population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer" title="cervical cancer">cervical cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=HPV" title=" HPV"> HPV</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence%20hpv" title=" prevalence hpv"> prevalence hpv</a>, <a href="https://publications.waset.org/abstracts/search?q=squamous%20intraepithelial%20lesion" title=" squamous intraepithelial lesion"> squamous intraepithelial lesion</a> </p> <a href="https://publications.waset.org/abstracts/79528/prevalence-of-human-papillomavirus-in-squamous-intraepithelial-lesions-and-cervical-cancer-in-women-of-the-north-of-chihuahua-mexico" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79528.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Treatment of Histopathological Symptoms in N-Nitrosopyrrolidine Induced Changes in Lung Tissue by Isolated Flavonoid from Indigofera tinctoria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aastha%20Agarwal">Aastha Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Veena%20Sharma"> Veena Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> N-nitrosopyrollidine or NPYR is a tobacco-specific nitrosamine which upon intoxicated causes abnormal production of Reactive Oxygen Species disrupt the endogenous antioxidant system.

Generally, most of WES studies have focused on rare variants in coding exons and splicing-sites where missense substitutions lead to the alternation of protein product. Although focusing on this category of variants has revealed the mystery behind many inherited genetic diseases in recent years, a subset of them remained still inconclusive. Here, we present the result of our WES studies where analyzing only rare variants in coding regions was not conclusive but further investigation revealed the involvement of non-coding variants and copy number variations (CNV) in etiology of the diseases. Methods: Whole exome sequencing was performed using our standard protocols at Genome Quebec Innovation Center, Montreal, Canada. All bioinformatics analyses were done using in-house WES pipeline. Results: To date, we successfully identified several disease causing mutations within gene coding regions (e.g. SCARF2: Van den Ende-Gupta syndrome and SNAP29: 22q11.2 deletion syndrome) by using WES. In addition, we showed that variants in non-coding regions and CNV have also important value and should not be ignored and/or filtered out along the way of bioinformatics analysis on WES data. For instance, in patients with osteogenesis imperfecta type V and in patients with glucocorticoid deficiency, we identified variants in 5'UTR, resulting in the production of longer or truncating non-functional proteins. Furthermore, CNVs were identified as the main cause of the diseases in patients with metaphyseal dysplasia with maxillary hypoplasia and brachydactyly and in patients with osteogenesis imperfecta type VII. Conclusions: Our study highlights the importance of considering non-coding variants and CNVs during interpretation of WES data, as they can be the only cause of disease under investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=whole%20exome%20sequencing%20data" title="whole exome sequencing data">whole exome sequencing data</a>, <a href="https://publications.waset.org/abstracts/search?q=non-coding%20variants" title=" non-coding variants"> non-coding variants</a>, <a href="https://publications.waset.org/abstracts/search?q=copy%20number%20variations" title=" copy number variations"> copy number variations</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20diseases" title=" rare diseases"> rare diseases</a> </p> <a href="https://publications.waset.org/abstracts/24069/whole-exome-sequencing-data-analysis-of-rare-diseases-non-coding-variants-and-copy-number-variations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">419</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Enamel Structure Defect, the Rare Dental Anomaly: Isolated or Syndromic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nehal%20F.%20Hassib">Nehal F.

Amelogenesis, the process of enamel formation, is regulated by multiple genes to ensure normal, defect-free enamel. Defective enamel manifests as hypoplasia or as amelogenesis imperfecta (AI), which may occur in isolation or as part of a syndrome. This study presents 29 patients from 18 unrelated families (16 females and 13 males) who exhibited distinctive enamel abnormalities. We conducted thorough clinical examinations and requested laboratory and radiological investigations. Blood samples were collected for molecular analysis, utilizing a targeted panel for known AI variants and whole exome sequencing for unknown variants. Eleven variants linked to enamel anomalies were identified: four genes associated with isolated AI (WDR72, ACP4, SLC24A4, and FAM83H) and seven associated with syndromic forms, including enamel renal syndrome (FAM20A), tricho-dento-osseous syndrome (DLX3), Jalili syndrome (CNNM4), and others linked to neurological and mitochondrial disorders, skeletal dysplasia, and peroxisome disorders. Abnormal oral and dental phenotypes in individuals may indicate serious inherited disorders. Enamel defects have significant implications for aesthetics, function, and patients' psychological well-being. Dental examination, alongside clinical and molecular investigations, is crucial for the accurate diagnosis and prediction of inherited conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amelogenesis%20imperfecta" title="amelogenesis imperfecta">amelogenesis imperfecta</a>, <a href="https://publications.waset.org/abstracts/search?q=enamel%20defect" title=" enamel defect"> enamel defect</a>, <a href="https://publications.waset.org/abstracts/search?q=Enamel%20renal%20syndrome" title=" Enamel renal syndrome"> Enamel renal syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=DLX3" title=" DLX3"> DLX3</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalili%20syndrome" title=" Jalili syndrome"> Jalili syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=WDR72" title=" WDR72"> WDR72</a>, <a href="https://publications.waset.org/abstracts/search?q=FAM83H" title=" FAM83H"> FAM83H</a>, <a href="https://publications.waset.org/abstracts/search?q=whole%20exome%20sequencing" title=" whole exome sequencing"> whole exome sequencing</a> </p> <a href="https://publications.waset.org/abstracts/191884/enamel-structure-defect-the-rare-dental-anomaly-isolated-or-syndromic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">25</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Application of Topical Imiquimod for Treatment Cervical Intraepithelial Neoplasia in Young Women: A Preliminary Result of a Pilot Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phill-Seung%20Jung">Phill-Seung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Yeon%20Kim"> Dae-Yeon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: In young, especially nulliparous women, it is not easy to decide on excisional therapy for cervical intraepithelial neoplasia (CIN). We aimed to evaluate how effective topical imiquimod is in the treatment of high-grade CIN so that excisional therapy can be avoided in young women. Methods: Patients with CIN were allocated to this pilot study. They did not want excisional therapy and agreed with topical imiquimod therapy, which required once-a-week hospital visit for 8 weeks for the application of imiquimod to the cervix by a gynecologic oncologist. If the lesion got worse during treatment, it was decided to convert imiquimod therapy to excisional therapy. Results: A total of 36 patients with a median age of 29 years (range, 22–41 years) agreed to receive topical imiquimod therapy. Of these, 32 patients (88.9%) were positive for high-risk human papillomavirus (HR HPV). Twenty-five patients (69.4%) had low-grade squamous intraepithelial lesion (LSIL), and 11 (30.6%) had high-grade squamous intraepithelial lesion (HSIL) on their initial LBC. Twenty-eight patients underwent punch biopsy, which showed CIN 1 in 7 (19.4%), CIN 2 in 11 (30.6%), and CIN 3 in 10 (27.8%) patients. Twenty patients finished the 8-week imiquimod therapy. Among them, 14 patients had CIN 2 or 3, and 6 patients had CIN 1. HR HPV was positive in 12 patients. On the last examination, 14 patients (70.0%) had negative intraepithelial lesions, 3 (15.0%) had atypical squamous cells of undetermined significance, and 1 (5.0%) had LSIL. Two patients had persistent HSIL: 1 patient underwent loop electrosurgical excision procedure, resulting in CIN 3 with positive resection margin, and the other patient underwent punch biopsy, resulting in intermediate cells and restarted imiquimod therapy. Only 7 patients were negative for HR HPV. Conclusions: This study showed that topical imiquimod therapy was effective for the treatment of high-grade CIN, with a histologic regression rate of 85.7% (14/20) and HPV eradication rate of 25.0% (8/32). Based on our findings, topical imiquimod therapy might have a successful therapeutic effect in young women with CIN 2-3 so that they can avoid excisional therapy. In addition, it could be a more reassuring treatment option for CIN 1 than just follow-up after few months. To confirm its efficacy, a phase II study with larger cohort would be needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imiquimod" title="Imiquimod">Imiquimod</a>, <a href="https://publications.waset.org/abstracts/search?q=Cervical%20Intraepthelial%20Neoplasia" title=" Cervical Intraepthelial Neoplasia"> Cervical Intraepthelial Neoplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=Cervical%20Dysplasia" title=" Cervical Dysplasia"> Cervical Dysplasia</a>, <a href="https://publications.waset.org/abstracts/search?q=Human%20Papillomavirus" title=" Human Papillomavirus"> Human Papillomavirus</a> </p> <a href="https://publications.waset.org/abstracts/48784/application-of-topical-imiquimod-for-treatment-cervical-intraepithelial-neoplasia-in-young-women-a-preliminary-result-of-a-pilot-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48784.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Whole Exome Sequencing in Characterizing Mysterious Crippling Disorder in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swarkar%20Sharma">Swarkar Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Ekta%20Rai"> Ekta Rai</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Mahajan"> Ankit Mahajan</a>, <a href="https://publications.waset.org/abstracts/search?q=Parvinder%20Kumar"> Parvinder Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoj%20K%20Dhar"> Manoj K Dhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sushil%20Razdan"> Sushil Razdan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kumarasamy%20Thangaraj"> Kumarasamy Thangaraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Carol%20Wise"> Carol Wise</a>, <a href="https://publications.waset.org/abstracts/search?q=Shiro%20Ikegawa%20M.D."> Shiro Ikegawa M.D.</a>, <a href="https://publications.waset.org/abstracts/search?q=K.K.%20Pandita%20M.D."> K.K.

A rare mysterious skeletal disorder that remained unidentified for decades and rendered many people physically challenged and disabled for life has been reported in an isolated remote village ‘Arai’ of Poonch district of Jammu and Kashmir. This village is located deep in mountains and the population residing in the region is highly consanguineous. In our survey of the region, 70 affected people were reported, showing similar phenotype, in the village with a population of approximately 5000 individuals. We were able to collect samples from two multi generational extended families from the village. Through Whole Exome sequencing (WES), we identified a rare variation NM_003880.3:c.156C>A NP_003871.1:p.Cys52Ter, which results in introduction of premature stop codon in WISP3 gene. We found this variation perfectly segregating with the disease in one of the family. However, this variation was absent in other family. Interestingly, a novel splice site mutation at position c.643+1G>A of WISP3 gene, perfectly segregating with the disease was observed in the second family. Thus, exploiting WES and putting different evidences together (familial histories and genetic data, clinical features, radiological and biochemical tests and findings), the disease has finally been diagnosed as a very rare recessive hereditary skeletal disease “Progressive Pseudorheumatoid Arthropathy of Childhood” (PPAC) also known as “Spondyloepiphyseal Dysplasia Tarda with Progressive Arthropathy” (SEDT-PA). This genetic characterization and identification of the disease causing mutations will aid in genetic counseling, critically required to curb this rare disorder and to prevent its appearance in future generations in the population. Further, understanding of the role of WISP3 gene the biological pathways should help in developing treatment for the disorder. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=whole%20exome%20sequencing" title="whole exome sequencing">whole exome sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=Next%20Generation%20Sequencing" title=" Next Generation Sequencing"> Next Generation Sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=rare%20disorders" title=" rare disorders"> rare disorders</a> </p> <a href="https://publications.waset.org/abstracts/17895/whole-exome-sequencing-in-characterizing-mysterious-crippling-disorder-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Molecular Alterations Shed Light on Alteration of Methionine Metabolism in Gastric Intestinal Metaplesia; Insight for Treatment Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nigatu%20Tadesse">Nigatu Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying%20Liu"> Ying Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Li"> Juan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Ming%20Liu"> Hong Ming Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gastric carcinogenesis is a lengthy process of histopathological transition from normal to atrophic gastritis (AG) to intestinal metaplasia (GIM), dysplasia toward gastric cancer (GC). The stage of GIM identified as precancerous lesions with resistance to H-pylori eradication and recurrence after endoscopic surgical resection therapies. GIM divided in to two morphologically distinct phenotypes such as complete GIM bearing intestinal type morphology whereas the incomplete type has colonic type morphology. The incomplete type GIM considered to be the greatest risk factor for the development of GC. Studies indicated the expression of the caudal type homeobox 2 (CDX2) gene is responsible for the development of complete GIM but its progressive downregulation from incomplete metaplasia toward advanced GC identified as the risk for IM progression and neoplastic transformation. The downregulation of CDX2 gene have promoted cell growth and proliferation in gastric and colon cancers and ascribed in chemo-treatment inefficacies. CDX2 downregulated through promoter region hypermethylation in which the methylation frequency positively correlated with the dietary history of the patients, suggesting the role of diet as methyl carbon donor sources such as methionine. However, the metabolism of exogenous methionine is yet unclear. Targeting exogenous methionine metabolism has become a promising approach to limits tumor cell growth, proliferation and progression and increase treatment outcome. This review article discusses molecular alterations that could shed light on the potential of exogenous methionine metabolisms, such as gut microbiota alteration as sources of methionine to host cells, metabolic pathway signaling via PI3K/AKt/mTORC1-c-MYC to rewire exogenous methionine and signature of increased gene methylation index, cell growth and proliferation in GIM, with insights to new treatment avenue via targeting methionine metabolism, and the need for future integrated studies on molecular alterations and metabolomics to uncover altered methionine metabolism and characterization of CDX2 methylation in gastric intestinal metaplasia for potential therapeutic exploitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=altered%20methionine%20metabolism" title="altered methionine metabolism">altered methionine metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=Intestinal%20metaplesia" title=" Intestinal metaplesia"> Intestinal metaplesia</a>, <a href="https://publications.waset.org/abstracts/search?q=CDX2%20gene" title=" CDX2 gene"> CDX2 gene</a>, <a href="https://publications.waset.org/abstracts/search?q=gastric%20cancer" title=" gastric cancer"> gastric cancer</a> </p> <a href="https://publications.waset.org/abstracts/184882/molecular-alterations-shed-light-on-alteration-of-methionine-metabolism-in-gastric-intestinal-metaplesia-insight-for-treatment-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184882.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Barriers and Facilitators for Telehealth Use during Cervical Cancer Screening and Care: A Literature Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reuben%20Mugisha">Reuben Mugisha</a>, <a href="https://publications.waset.org/abstracts/search?q=Stella%20Bakibinga"> Stella Bakibinga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cervical cancer burden is a global threat, but more so in low income settings where more than 85% of mortality cases occur due to lack of sufficient screening programs. There is consequently a lack of early detection of cancer and precancerous cells among women. Studies show that 3% to 35% of deaths could have been avoided through early screening depending on prognosis, disease progression, environmental and lifestyle factors. In this study, a systematic literature review is undertaken to understand potential barriers and facilitators as documented in previous studies that focus on the application of telehealth in cervical cancer screening programs for early detection of cancer and precancerous cells. The study informs future studies especially those from low income settings about lessons learned from previous studies and how to be best prepared while planning to implement telehealth for cervical cancer screening. It further identifies the knowledge gaps in the research area and makes recommendations. Using a specified selection criterion, 15 different articles are analyzed based on the study’s aim, theory or conceptual framework used, method applied, study findings and conclusion. Results are then tabulated and presented thematically to better inform readers about emerging facts on barriers and facilitators to telehealth implementation as documented in the reviewed articles, and how they consequently lead to evidence informed conclusions that are relevant to telehealth implementation for cervical cancer screening. Preliminary findings of this study underscore that use of low cost mobile colposcope is an appealing option in cervical cancer screening, particularly when coupled with onsite treatment of suspicious lesions. These tools relay cervical images to the online databases for storage and retrieval, they permit integration of connected devices at the point of care to rapidly collect clinical data for further analysis of the prevalence of cervical dysplasia and cervical cancer. Results however reveal the need for population sensitization prior to use of mobile colposcopies among patients, standardization of mobile colposcopy programs across screening partners, sufficient logistics and good connectivity, experienced experts to review image cases at the point-of-care as important facilitators to the implementation of mobile colposcope as a telehealth cervical cancer screening mechanism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervical%20cancer%20screening" title="cervical cancer screening">cervical cancer screening</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20technology" title=" digital technology"> digital technology</a>, <a href="https://publications.waset.org/abstracts/search?q=hand-held%20colposcopy" title=" hand-held colposcopy"> hand-held colposcopy</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge-sharing" title=" knowledge-sharing"> knowledge-sharing</a> </p> <a href="https://publications.waset.org/abstracts/58764/barriers-and-facilitators-for-telehealth-use-during-cervical-cancer-screening-and-care-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58764.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Revolutionizing Healthcare Communication: The Transformative Role of Natural Language Processing and Artificial Intelligence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Halimat%20M.%20Ajose-Adeogun">Halimat M.

NLP, a multidisciplinary area that combines rule-based linguistics, machine learning, and deep learning, enables computers to analyze and comprehend human language. NLP applications in medicine range from tackling issues in electronic health records (EHR) and psychiatry to improving diagnostic precision in orthopedic surgery and optimizing clinical procedures with novel technologies like chatbots. The technology shows promise in a variety of medical sectors, including quicker access to medical records, faster decision-making for healthcare personnel, diagnosing dysplasia in Barrett's esophagus, boosting radiology report quality, and so on. However, successful adoption requires training for healthcare workers, fostering a deep understanding of NLP components, and highlighting the significance of validation before actual application. Despite prevailing challenges, continuous multidisciplinary research and collaboration are critical for overcoming restrictions and paving the way for the revolutionary integration of NLP into medical practice. This integration has the potential to improve patient care, research outcomes, and administrative efficiency. The research methodology includes using NLP techniques for Sentiment Analysis and Emotion Recognition, such as evaluating text or audio data to determine the sentiment and emotional nuances communicated by users, which is essential for designing a responsive and sympathetic chatbot. Furthermore, the project includes the adoption of a Personalized Intervention strategy, in which chatbots are designed to personalize responses by merging NLP algorithms with specific user profiles, treatment history, and emotional states. The synergy between NLP and personalized medicine principles is critical for tailoring chatbot interactions to each user's demands and conditions, hence increasing the efficacy of mental health care. A detailed survey corroborated this synergy, revealing a remarkable 20% increase in patient satisfaction levels and a 30% reduction in workloads for healthcare practitioners. The poll, which focused on health outcomes and was administered to both patients and healthcare professionals, highlights the improved efficiency and favorable influence on the broader healthcare ecosystem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20language%20processing" title="natural language processing">natural language processing</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20communication" title=" healthcare communication"> healthcare communication</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20health%20records" title=" electronic health records"> electronic health records</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20care" title=" patient care"> patient care</a> </p> <a href="https://publications.waset.org/abstracts/178940/revolutionizing-healthcare-communication-the-transformative-role-of-natural-language-processing-and-artificial-intelligence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178940.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Abnormal Pap Smear Detection by Application of Revised Bethesda System in Commercial Sex Workers and a Control Group: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Manghani">Priyanka Manghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Manthan%20Patel"> Manthan Patel</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Peddawad"> Rahul Peddawad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cervical Cancer is a major public health hurdle in the area of women’s health. The most common cause of Cervical Cancer is the Human Papilloma Virus (HPV). Human papilloma virus has various genotypes, with HPV 16 and HPV 18 being the major etiological factor causing carcinoma of the Cervix. Early screening and detection by Papanicolaou Smears (PAP) is an effective method for identifying premalignant and malignant lesions. In case of existing pre- malignant lesions /cervical dysplasia’s found with HPV 16 or 18, appropriate follow up can be done to prevent it from developing into a neoplasm. Aims and Objectives: Primary Aim; To study various abnormal cervical cytology reports as detected by Pap Smear Tests, using the Bethesda System in women at a Tertiary Care Hospital. Secondary Aim; To discuss the importance of Pap smear in Cervical Cancer Screening Program. Materials and Methods: Our study is a prospective study, based on 101 women who attended the Out-patient department of Obstetrics and Gynecology at a tertiary care hospital in age group 20-40 years with chief complaints of white/foul vaginal discharge, post-coital Bleeding, low back pain, irregular menstruation, etc. 60 women, who were tested, of the total no of women, were commercial sex workers, thus being a high-risk group for HPV infection. All women underwent conventional cytology. For all the abnormal smears, further cervical biopsies were done, and the final diagnosis was done on the basis of histopathology (gold standard). Results: In all these patients, 16 patients presented with normal smears out of which 2 belonged to the category of commercial sex workers (3.33%) and 14 being from the normal/control group (34.15%). 44 women presented with inflammatory smears out of which 30 were commercial sex workers (50%) and 14 from the control Group (34.15%). A total of 11 women presented with infectious etiology with 6 being commercial sex workers (10%) and 5 (12.2%) being in the control group. A total of 8 patients presented with low-grade squamous intra epithelial lesion (LSIL) with 7 (11.7%) being commercial sex workers and 1(2.44%) patient belonging to the control group. A Total of 7 patients presented with high-grade squamous intraepithelial lesion (HSIL) with 6 (10%) being commercial sex workers and 1 (2.44%) belonging to the control group. 9 patients in total presented with atypical squamous cells of undetermined significance (ASCUS) with 6(10%) being commercial sex workers and 3 (7.32%) belonging to the control group. Squamous cell carcinoma(SCC) presence was found only in 1(1.7%) commercial sex worker. Conclusion – We conclude that HSIL, LSIL, SCC and sexually related infections are comparatively more common in vulnerable groups such as sex workers due to a variety of factors such as multiple sexual partners and poor genital hygiene. Early screening and follow up interventions are highly needed for them along with Health education for risk factors and to emphasize on the importance of Pap smear screening. <p
