surgically with endoscopic or open carpal tunnel release (CTR). Rheumatoid arthritis (RA) is a known risk factor for Carpal Tunnel Syndrome (CTS) and is believed to be related to compression of the median nerve secondary to inflammation. We aimed to analyze national trends, outcomes, and patient-specific comorbidities associated with ECTR and OCTR in patients with RA. Methods: A retrospective cohort study was conducted using the PearlDiver database, identifying 683 RA patients undergoing ECTR and 4234 undergoing OCTR between 2010 and 2014. Demographic data, comorbidities, and complication rates were analyzed. Univariate and multivariable analyses assessed differences between the treatment methods. Results:  Patients with RA undergoing ECTR in comparison to OCTR had no significant differences in medical comorbidities such as hypertension, obesity, chronic kidney disease, hypothyroidism and diabetes mellitus. Patients in the ECTR group reported a risk ratio of 1.44 (95%CI: 1.10-1.89, p=0.01) of requiring repeat procedures within 90 days of the initial procedure. Five-year trends in ECTR and OCTR procedures reported a combined annual growth rate of 5.6% and 13.15, respectively. Conclusion: Endoscopic and open approaches to CTR are important considerations in surgical planning. RA and ECTR have previously been identified as independent risk factors for revision CTR. Our study has identified the 90-day risk of repeat procedures to be elevated in the ECTR group in comparison to the OCTR group. Additionally, the growth of OCTR procedures has outpaced the growth of ECTR procedures in the same period, likely in response to the trend of ECTR leading to higher rates of repeat procedures. The need for revision following ECTR in patients with RA could be related to chronic inflammation leading to transverse carpal ligament thickening and concomitant tenosynovitis. Future directions could include further characterization of repeat procedures performed in this subset of patients.  <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20treatment%20of%20carpal%20tunnel%20syndrome" title="endoscopic treatment of carpal tunnel syndrome">endoscopic treatment of carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20treatment%20of%20carpal%20tunnel%20syndrome" title=" open treatment of carpal tunnel syndrome"> open treatment of carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=rheumatoid%20arthritis" title=" rheumatoid arthritis"> rheumatoid arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=trends%20analysis" title=" trends analysis"> trends analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title=" carpal tunnel syndrome"> carpal tunnel syndrome</a> </p> <a href="https://publications.waset.org/abstracts/170987/trends-in-endoscopic-versus-open-treatment-of-carpal-tunnel-syndrome-in-rheumatoid-arthritis-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170987.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">9096</span> Endoscopic Versus Open Treatment of Carpal Tunnel Syndrome: Postoperative Complications in Patients on Anticoagulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arman%20Kishan">Arman Kishan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Haft"> Mark Haft</a>, <a href="https://publications.waset.org/abstracts/search?q=Kiyanna%20Thomas"> Kiyanna Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Duc%20Nguyen"> Duc Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawn%20Laporte"> Dawn Laporte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Patients receiving anticoagulation therapy frequently experience increased rates of postoperative complications. Presently, limited data exist regarding the outcomes of patients undergoing carpal tunnel release surgery (CTR) while on anticoagulation. Our objective is to examine and compare the occurrence of complications in patients on anticoagulation who underwent either endoscopic CTR (ECTR) or open CTR (OCTR) for CTS. Methods: The Trinet X database was utilized to retrospectively identify patients who underwent OCTR or ECTR while concurrently on anticoagulation. Demographic data, medical comorbidities, and complication rates were analyzed. We used multivariable analysis to identify differences in postoperative complications, including wound infection within 90 days, wound dehiscence within 90 days, and intraoperative median nerve injury between the two surgical methods in patients on anticoagulation. Results: A total of 10,919 carpal tunnel syndrome patients on anticoagulation were included in the study, with 9082 and 1837 undergoing OCTR and ECTR, respectively. Among patients on anticoagulation, those undergoing ECTR exhibited a significantly lower occurrence of 90-day wound infection (p < 0.001) and nerve injury (p < 0.001) compared to those who underwent OCTR. However, there was no statistically significant difference in the risk of 90-day wound dehiscence between the two groups (p = 0.323). Conclusion:  In prior studies, ECTR demonstrated reduced rates of postoperative complications compared to OCTR in the general population. Our study demonstrates that among patients on anticoagulation, those undergoing ECTR experienced a significantly lower incidence of 90-day wound infection and nerve injury, with risk reductions of 35% and 40%, respectively. These findings support using ECTR as a preferred surgical method for patients with CTS who are on anticoagulation therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20treatment%20of%20carpal%20tunnel%20syndrome" title="endoscopic treatment of carpal tunnel syndrome">endoscopic treatment of carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20treatment%20of%20carpal%20tunnel%20syndrome" title=" open treatment of carpal tunnel syndrome"> open treatment of carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=postoperative%20complications%20in%20patients%20on%20anticoagulation" title=" postoperative complications in patients on anticoagulation"> postoperative complications in patients on anticoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title=" carpal tunnel syndrome"> carpal tunnel syndrome</a> </p> <a href="https://publications.waset.org/abstracts/170988/endoscopic-versus-open-treatment-of-carpal-tunnel-syndrome-postoperative-complications-in-patients-on-anticoagulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170988.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">68</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">9095</span> Ultrasound Guided Treatment of Carpal Tunnel Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazem%20Shakouri">Kazem Shakouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Pishgahi"> Alireza Pishgahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Homayoun%20Sadeghi-bBazargani"> Homayoun Sadeghi-bBazargani</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahla%20Dareshiri"> Shahla Dareshiri </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Carpal Tunnel Syndrome has numerous nonsurgical treatments including splint, physical therapy and corticosteroid injections. Aim: The purpose of this study was to evaluate the effectiveness of an ultrasound guided treatment procedure, for individuals with severe carpal tunnel syndrome. Materials and Method: 20 patients with an electrodiagnostic evidence of severe carpal tunnel syndrome were treated by an office-based ultrasound guided procedure (combination of percutaneous needle release of carpal tunnel and corticosteroid injection). Electrodiagnostic (nerve conduction study), clinical (Boston Carpal Tunnel Questionnaire, grip strength) and ultrasonic (median nerve and carpal tunnel cross-sectional area) measurements were recorded at baseline and one month after intervention. Results: Our preliminary data analysis showed that in one month follow up, patients had a significantly smaller cross-sectional area of the median nerve compared to pretreatment values (mean difference 0.06; 95%CI: 0.02-0.1; p < 0.001). In addition, patients had significantly less functional impairment (mean difference 35; 95% CI:28.7-43.4 ; p < 0.001), and an improved hand grip strength in one month follow up (mean difference 5.4; 95%CI: 3.1-7.8; p < 0.001;). There were no significant complications. Conclusion: Patients with severe carpal tunnel syndrome, who are candidates for surgical intervention, can consider office-based ultrasound guided needle release of carpal tunnel as an alternative safe treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carpal%20Tunnel%20Syndrome" title="Carpal Tunnel Syndrome">Carpal Tunnel Syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=needle%20release" title=" needle release"> needle release</a>, <a href="https://publications.waset.org/abstracts/search?q=pain" title=" pain"> pain</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/74847/ultrasound-guided-treatment-of-carpal-tunnel-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74847.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">247</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">9094</span> Endoscopic Versus Open Treatment of Carpal Tunnel Syndrome: Postoperative Complications in Patients with Diabetes Mellitus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arman%20Kishan">Arman Kishan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Haft"> Mark Haft</a>, <a href="https://publications.waset.org/abstracts/search?q=Steve%20Li"> Steve Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Duc%20Nguyen"> Duc Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Dawn%20Laporte"> Dawn Laporte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: Patients with Type 2 diabetes (T2DM) often face higher postoperative complication rates. Limited data exist on outcomes in T2DM patients undergoing carpal tunnel release (CTR). This study aims to compare complication rates between endoscopic CTR (ECTR) and open CTR (OCTR) in patients with T2DM. Methods: This was a retrospective cohort study using the TriNetX database of 56741 patients with T2DM undergoing ECTR (N= 14,949) or OCTR (N= 41,792). Demographic data, medical comorbidities, and complication rates were analyzed. We used multivariable analysis to identify differences in postoperative complication rates between the two treatment methods in patients with T2DM. Results: Patients with T2DM undergoing ECTR had a significantly lower incidence of 90-day wound infection (p < 0.001), 90-day wound dehiscence (p < 0.001), and nerve injury (p < 0.001) when compared to patients who underwent OCTR. After matching, there was a significantly higher number of T2DM patients undergoing ECTR who had peripheral vascular disease (p = 0.045) and hypertension (p = 0.020) when compared to the OCTR group. These patients also had a lower incidence of fluid and electrolyte disorders (p = 0.002) and chronic blood loss anemia (p = 0.025). Conclusion: ECTR presents a superior choice for T2DM patients undergoing CTR, yielding significantly lower rates of wound infection, wound dehiscence, and nerve injury within 90 days post-surgery—reducing the risk by 31%, 48%, and 59%, respectively. These findings support the adoption of ECTR as the preferred method in this patient population, potentially leading to improved postoperative outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20treatment%20of%20carpal%20tunnel%20syndrome" title="endoscopic treatment of carpal tunnel syndrome">endoscopic treatment of carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20treatment%20of%20carpal%20tunnel%20syndrome" title=" open treatment of carpal tunnel syndrome"> open treatment of carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title=" carpal tunnel syndrome"> carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=postoperative%20complications%20in%20patients%20with%20diabetes%20mellitus" title=" postoperative complications in patients with diabetes mellitus"> postoperative complications in patients with diabetes mellitus</a> </p> <a href="https://publications.waset.org/abstracts/170989/endoscopic-versus-open-treatment-of-carpal-tunnel-syndrome-postoperative-complications-in-patients-with-diabetes-mellitus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170989.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">69</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">9093</span> Central Palmar Necrosis Following Steroid Injections for the Treatment of Carpal Tunnel Syndrome: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ridwanul%20Hassan">M.

Ischaemia is a rare complication with very few cases reported in the literature. Methods: We report a case of a 50-year-old female that presented with a necrotic wound to her left palm one month after a steroid injection into the carpal tunnel. She had a 2-year history of CTS in her left hand that was treated with six previous steroid injections in primary care during this period. The wound evolved from a blister to a necrotic ulcer which led to a painful, hollow defect in the centre of her palm. She did not report any history of trauma, nor did she have any co-morbidities. Clinical photographs were taken. Results: On examination, she had a 0.5 cmx1 cm defect in the palm of her left hand down to aponeurosis. There was purulent discharge in the wound with surrounding erythema but no spreading cellulitis. She had full function of her fingers but was very tender on movements and at rest. She was admitted for intravenous antibiotics and underwent a debridement, washout, and carpal tunnel release the next day. The defect was packed to heal by secondary intention and has now fully healed one month following her operation. Conclusions: This is an extremely rare complication of steroid injections to the carpal tunnel and may have been avoided by earlier referral for surgery rather than treatment using multiple steroid injections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand%20surgery" title="hand surgery">hand surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=complication" title=" complication"> complication</a>, <a href="https://publications.waset.org/abstracts/search?q=rare" title=" rare"> rare</a>, <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title=" carpal tunnel syndrome"> carpal tunnel syndrome</a> </p> <a href="https://publications.waset.org/abstracts/152984/central-palmar-necrosis-following-steroid-injections-for-the-treatment-of-carpal-tunnel-syndrome-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152984.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">112</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">9092</span> Median Versus Ulnar Medial Thenar Motor Recording in Diagnosis Of Carpal Tunnel Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim of the work: This study proposed to assess the role of the median versus ulnar medial thenar motor (MTM) recording in supporting the diagnosis of carpal tunnel syndrome (CTS). Patients and methods: The present study included 130 hands (70 CTS and 60 controls). Clinical examination was done for all patients. The following tests were done (using surface electrodes recording) for patients and control: (1) sensory nerve conduction studies: median nerve, ulnar nerve and median versus ulnar digit four sensory study; (2) motor nerve conduction studies: median nerve, ulnar nerve, median (second lumbrical) versus ulnar (interosseous) (2-LINT) motor study and median versus ulnar (MTM) study. Results: The tests with higher sensitivity in diagnosing CTS were median versus ulnar (2-LINT) motor latency difference (87.1%), median versus ulnar (MTM) motor latency difference (80%) and median versus ulnar digit four sensory latency differences (91.4%). There was no statistically significant difference between median versus ulnar (MTM) motor latency difference with both median versus ulnar (2-LINT) motor latency difference and median versus ulnar digit four sensory latency difference (P > 0.05) as regards the confirmation of CTS. Conclusions: Median versus ulnar (MTM) motor latency difference has high sensitivity and specificity for the diagnosis of CTS as for both median versus ulnar (2-LINT) motor latency difference and median versus ulnar digit four sensory latency differences. It can be considered a useful neurophysiological test to be used in combination with another median versus ulnar comparative tests for confirming the diagnosis of CTS beside other well-known electrophysiological tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title="carpal tunnel syndrome">carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=medial%20thenar%20motor" title=" medial thenar motor"> medial thenar motor</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20nerve" title=" median nerve"> median nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=ulnar%20nerve" title=" ulnar nerve"> ulnar nerve</a> </p> <a href="https://publications.waset.org/abstracts/29852/median-versus-ulnar-medial-thenar-motor-recording-in-diagnosis-of-carpal-tunnel-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29852.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">443</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">9091</span> Role of Grey Scale Ultrasound Including Elastography in Grading the Severity of Carpal Tunnel Syndrome - A Comparative Cross-sectional Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arjun%20Prakash">Arjun Prakash</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinutha%20H."> Vinutha H.</a>, <a href="https://publications.waset.org/abstracts/search?q=Karthik%20N."> Karthik N.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> BACKGROUND: Carpal tunnel syndrome (CTS) is a common entrapment neuropathy with an estimated prevalence of 0.6 - 5.8% in the general adult population. It is caused by compression of the Median Nerve (MN) at the wrist as it passes through a narrow osteofibrous canal. Presently, the diagnosis is established by the clinical symptoms and physical examination and Nerve conduction study (NCS) is used to assess its severity. However, it is considered to be painful, time consuming and expensive, with a false-negative rate between 16 - 34%. Ultrasonography (USG) is now increasingly used as a diagnostic tool in CTS due to its non-invasive nature, increased accessibility and relatively low cost. Elastography is a newer modality in USG which helps to assess stiffness of tissues. However, there is limited available literature about its applications in peripheral nerves. OBJECTIVES: Our objectives were to measure the Cross-Sectional Area (CSA) and elasticity of MN at the carpal tunnel using Grey scale Ultrasonography (USG), Strain Elastography (SE) and Shear Wave Elastography (SWE). We also made an attempt to independently evaluate the role of Gray scale USG, SE and SWE in grading the severity of CTS, keeping NCS as the gold standard. MATERIALS AND METHODS: After approval from the Institutional Ethics Review Board, we conducted a comparative cross sectional study for a period of 18 months. The participants were divided into two groups. Group A consisted of 54 patients with clinically diagnosed CTS who underwent NCS, and Group B consisted of 50 controls without any clinical symptoms of CTS. All Ultrasound examinations were performed on SAMSUNG RS 80 EVO Ultrasound machine with 2 - 9 Mega Hertz linear probe. In both groups, CSA of the MN was measured on Grey scale USG, and its elasticity was measured at the carpal tunnel (in terms of Strain ratio and Shear Modulus). The variables were compared between both groups by using ‘Independent t test’, and subgroup analyses were performed using one-way analysis of variance. Receiver operating characteristic curves were used to evaluate the diagnostic performance of each variable. RESULTS: The mean CSA of the MN was 13.60 + 3.201 mm2 and 9.17 + 1.665 mm2 in Group A and Group B, respectively (p < 0.001). The mean SWE was 30.65 + 12.996 kPa and 17.33 + 2.919 kPa in Group A and Group B, respectively (p < 0.001), and the mean Strain ratio was 7.545 + 2.017 and 5.802 + 1.153 in Group A and Group B respectively (p < 0.001). CONCLUSION: The combined use of Gray scale USG, SE and SWE is extremely useful in grading the severity of CTS and can be used as a painless and cost-effective alternative to NCS. Early diagnosis and grading of CTS and effective treatment is essential to avoid permanent nerve damage and functional disability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel" title="carpal tunnel">carpal tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=elastography" title=" elastography"> elastography</a>, <a href="https://publications.waset.org/abstracts/search?q=nerve%20conduction%20study" title=" nerve conduction study"> nerve conduction study</a> </p> <a href="https://publications.waset.org/abstracts/167632/role-of-grey-scale-ultrasound-including-elastography-in-grading-the-severity-of-carpal-tunnel-syndrome-a-comparative-cross-sectional-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167632.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">101</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">9090</span> Ulnar Nerve Changes Associated with Carpal Tunnel Syndrome and Effect on Median Ersus Ulnar Comparative Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20K.%20Aziz%20Saba">Emmanuel K.

The aim of this study was to assess the involvement of sensory and/or motor ulnar nerve fibers in patients with CTS and whether this affects the accuracy of the median versus ulnar sensory and motor comparative tests. Patients and methods: The present study included 145 CTS hands and 71 asymptomatic control hands. Clinical examination was done for all patients. The following tests were done for the patients and control: (1) Sensory conduction studies: median nerve, ulnar nerve, dorsal ulnar cutaneous nerve and median versus ulnar digit (D) four sensory comparative study; (2) Motor conduction studies: median nerve, ulnar nerve and median versus ulnar motor comparative study. Results: There were no statistically significant differences between patients and control group as regards parameters of ulnar motor study and dorsal ulnar cutaneous sensory conduction study. It was found that 17 CTS hands (11.7%) had ulnar sensory abnormalities in 17 different patients. The median versus ulnar sensory and motor comparative studies were abnormal among all these 17 CTS hands. There were statistically significant negative correlations between median motor latency and both ulnar sensory amplitudes recording D5 and D4. There were statistically significant positive correlations between median sensory conduction velocity and both ulnar sensory nerve action potential amplitude recording D5 and D4. Conclusions: There is ulnar sensory nerve abnormality among CTS patients. This abnormality affects the amplitude of ulnar sensory nerve action potential. The presence of abnormalities in ulnar nerve occurs in moderate and severe degrees of CTS. This does not affect the median versus ulnar sensory and motor comparative tests accuracy and validity for use in electrophysiological diagnosis of CTS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title="carpal tunnel syndrome">carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=ulnar%20nerve" title=" ulnar nerve"> ulnar nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20nerve" title=" median nerve"> median nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20versus%20ulnar%20comparative%20study" title=" median versus ulnar comparative study"> median versus ulnar comparative study</a>, <a href="https://publications.waset.org/abstracts/search?q=dorsal%20ulnar%20cutaneous%20nerve" title=" dorsal ulnar cutaneous nerve"> dorsal ulnar cutaneous nerve</a> </p> <a href="https://publications.waset.org/abstracts/19196/ulnar-nerve-changes-associated-with-carpal-tunnel-syndrome-and-effect-on-median-ersus-ulnar-comparative-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19196.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">567</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">9089</span> Ulnar Nerve Changes Associated with Carpal Tunnel Syndrome Not Affecting Median versus Ulnar Comparative Studies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Sayed%20El-Tawab"> Sarah Sayed El-Tawab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to assess the involvement of ulnar sensory and/or motor nerve fibers in patients with carpal tunnel syndrome (CTS) and whether this affects the accuracy of the median versus ulnar comparative tests.

Yet, previous study may not quickly perform the measurement due to the use of a single element transducer for ultrasound image scanning. Therefore, previous system is not appropriate for being applied to clinical application. In the present study, B-mode ultrasound images of the wrist corresponding to movements of fingers from flexion to extension were acquired by clinical applicable real-time scanner. The kinetic trajectories of MN were off-line estimated utilizing two dimensional Baysian speckle tracking (TDBST) technique. The experiments were carried out from ten volunteers by ultrasound scanner at 12 MHz frequency. Results verified from phantom experiments have demonstrated that TDBST technique is able to detect the movement of MN based on signals of the past and present information and then to reduce the computational complications associated with the effect of such image quality as the resolution and contrast variations. Moreover, TDBST technique tended to be more accurate than that of the normalized cross correlation tracking (NCCT) technique used in previous study to detect movements of the MN in the wrist. In response to fingers’ flexion movement, the kinetic trajectory of the MN moved toward the ulnar-palmar direction, and then toward the radial-dorsal direction corresponding to the extensional movement. TDBST technique and the employed ultrasound image scanner have verified to be feasible to sensitively detect the kinetic trajectory and displacement of the MN. It thus could be further applied to diagnose CTS clinically and to improve the measurements to assess 3D trajectory of the MN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=baysian%20speckle%20tracking" title="baysian speckle tracking">baysian speckle tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=carpal%20tunnel%20syndrome" title=" carpal tunnel syndrome"> carpal tunnel syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=median%20nerve" title=" median nerve"> median nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20tracking" title=" motion tracking"> motion tracking</a> </p> <a href="https://publications.waset.org/abstracts/28816/assessment-of-kinetic-trajectory-of-the-median-nerve-from-wrist-ultrasound-images-using-two-dimensional-baysian-speckle-tracking-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28816.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">495</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">9087</span> Endoscopic Treatment of Esophageal Injuries Using Vacuum Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murad%20Gasanov">Murad Gasanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Shagen%20Danielyan"> Shagen Danielyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Gasanov"> Ali Gasanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Teterin"> Yuri Teterin</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Yartsev"> Peter Yartsev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Despite the advances made in modern surgery, the treatment of patients with esophageal injuries remains one of the most topical and complex issues. In recent years, high-technology minimally invasive methods, such as endoscopic vacuum therapy (EVT) in the treatment of esophageal injuries. The effectiveness of EVT has been sufficiently studied in case of failure of esophageal anastomoses, however the application of this method in case of mechanical esophageal injuries is limited by a small series of observations, indicating the necessity of additional study. Aim: The aim was to аnalyzed of own experience in the use of endoscopic vacuum therapy (EVT) in a comprehensive examination of patients with esophageal injuries. Methods: We analyzed the results of treatment of 24 patients with mechanical injuries of the esophagus for the period 2019-2021. Complex treatment of patients included the use of minimally invasive technologies, including percutaneous endoscopic gastrostomy (PEG), EVT and video-assisted thoracoscopic debridement. Evaluation of the effectiveness of treatment was carried out using multislice computed tomography (MSCT), endoscopy and laboratory tests. The duration of inpatient treatment and the duration of EVT, the number of system replacements, complications and mortality were taken into account. Result: EVT in patients with mechanical injuries of the esophagus allowed to achieve epithelialization of the esophageal defect in 21 patients (87.5%) in the form of linear scar on the site of perforation or pseudodiverticulum. Complications were noted in 4 patients (16.6%), including bleeding (2) and and esophageal stenosis in the perforation area (2). Lethal outcome was in one observation (4.2%). Conclusion. EVT may be the method of choice in complex treatment in patients with esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esophagus%20injuries" title="esophagus injuries">esophagus injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20to%20the%20esophagus" title=" damage to the esophagus"> damage to the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=perforation%20of%20the%20esophagus" title=" perforation of the esophagus"> perforation of the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=spontaneous%20perforation%20of%20the%20esophagus" title=" spontaneous perforation of the esophagus"> spontaneous perforation of the esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=mediastinitis" title=" mediastinitis"> mediastinitis</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20vacuum%20therapy" title=" endoscopic vacuum therapy"> endoscopic vacuum therapy</a> </p> <a href="https://publications.waset.org/abstracts/159374/endoscopic-treatment-of-esophageal-injuries-using-vacuum-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159374.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">105</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">9086</span> Behavioral Problems Among Down Syndrome Children in the Special Education Complex Peshawar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huma%20Atta">Huma Atta</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishrat%20Rehman"> Ishrat Rehman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umair"> Muhammad Umair</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To find out the effectiveness of Dr. Stein behavioural modification strategies among Down syndrome children’s behavioural problems.

This study is meant to introduce a modified technique of pin-in-plaster. Materials and methods: Fifty-four patients with distal radius fractures were followed up for one year. Patients were excluded if they had type B fractures according to AO classification, multiple injuries or pathological fractures, and were treated more than 7 days after injury. Range of motion and functional results were evaluated. Radiographic parameters including radial inclination, tilt, and height, were measured preoperatively and postoperatively. Results: The average radial tilt was 10.6° and radial height was 10.2 mm at the sixth month postoperatively. Three cases of pin tract infection were recorded, who were treated totally with oral antibiotics. There was no case of pin loosening. Of total 73 patients underwent surgery, three cases of radial nerve irritation were recorded at the time of cast removal. All of them resolved at the 6th month follow up. No median nerve compression and carpal tunnel syndrome have found. We also had no case of tendon injury. Conclusion: Our modified technique is effective to restore anatomic congruity and maintain reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distal%20radius%20fracture" title="distal radius fracture">distal radius fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=percutaneous%20pinning" title=" percutaneous pinning"> percutaneous pinning</a>, <a href="https://publications.waset.org/abstracts/search?q=pin-in-plaster" title=" pin-in-plaster"> pin-in-plaster</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20method%20of%20pin-in-plaster" title=" modified method of pin-in-plaster"> modified method of pin-in-plaster</a>, <a href="https://publications.waset.org/abstracts/search?q=operative%20treatment" title=" operative treatment"> operative treatment</a> </p> <a href="https://publications.waset.org/abstracts/34784/a-prospective-study-of-a-modified-pin-in-plaster-technique-for-treatment-of-distal-radius-fractures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34784.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">509</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">9082</span> Application of Applied Behavior Analysis Treatment to Children with Down Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olha%20Yarova">Olha Yarova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is a collaborative project between the American University of Central Asia and parent association of children with Down syndrome ‘Sunterra’ that took place in Bishkek, Kyrgyzstan. The purpose of the study was to explore whether principles and techniques of applied behavior analysis (ABA) could be used to teach children with Down syndrome socially significant behaviors. ABA is considered to be one of the most effective treatment for children with autism, but little research is done on the particularity of using ABA to children with Down syndrome. The data for the study was received during clinical observations; work with children with Down syndrome and interviews with their mothers. The results show that many ABA principles make the work with children with Down syndrome more effective. Although such children very rarely demonstrate aggressive behavior, they show a lot of escape-driven and attention seeking behaviors that are reinforced by their parents and educators. Thus functional assessment can be done to assess the function of problem behavior and to determine appropriate treatment. Prompting and prompting fading should be used to develop receptive and expressive language skills, and enhance motor development. Even though many children with Down syndrome work for praise, it is still relevant to use tangible reinforcement and to know how to remove them. Based on the results of the study, the training for parents of children with Down syndrome will be developed in Kyrgyzstan, country, where children with Down syndrome are not accepted to regular kindergartens and where doctors in maternity hospitals tell parents that their child will never talk, walk and recognize them <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=down%20syndrome" title="down syndrome">down syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=applied%20behavior%20analysis" title=" applied behavior analysis"> applied behavior analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20assessment" title=" functional assessment"> functional assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=problem%20behavior" title=" problem behavior"> problem behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement" title=" reinforcement"> reinforcement</a> </p> <a href="https://publications.waset.org/abstracts/71606/application-of-applied-behavior-analysis-treatment-to-children-with-down-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71606.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">275</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">9081</span> Endoscopic Pituitary Surgery: Learning Curve and Nasal Quality of Life</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Dupuy">Martin Dupuy</a>, <a href="https://publications.waset.org/abstracts/search?q=Solange%20Grunenwald"> Solange Grunenwald</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre-Louis%20Colombo"> Pierre-Louis Colombo</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurence%20Mahieu"> Laurence Mahieu</a>, <a href="https://publications.waset.org/abstracts/search?q=Pomone%20Richard"> Pomone Richard</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Bartoli"> Philippe Bartoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Endonasal endoscopic trans-sphenoidal surgery for pituitary tumours has become a mainstay of treatment over the last two decades. Although it is generally accepted that there is no significant difference between endoscopic versus microscopic approach for surgical outcomes (endocrine and ophthalmologic status), nasal morbidity seems to the benefit of endoscopic procedures. Minimally invasive endoscopic surgery needs an operative learning curve to achieve surgeon’s efficiency. This learning curve is now well known for surgical outcomes and complications rate, however, few data are available for nasal morbidity. The aim of our series is to document operative experience and nasal quality of life after (NQOL) endoscopic trans-sphenoidal surgery. The prospective pituitary surgical cohort consisted of 525 consecutives patients referred to our Skull Base Diseases Department. Endoscopic procedures were performed by a single neurosurgeon using an uninostril approach. NQOL was evaluated using the Sino-Nasal Test (SNOT-22), the Anterior Base Nasal Inventory (ASBNI) and the Skull Base Inventory Score (SBIS). Data were collected before surgery during hospital stay and 3 months after the surgery. The seventy first patients were compared to the latest 70 patients. There was no significant difference between comparison score before versus after surgery for SNOT-22, ASBNI and SBIS during the single surgeon’s learning curve. Our series demonstrates that in our institution there is no statistically significant learning curve for NQOL after uninostril endoscopic pituitary surgery. A careful progression through sinonasal structures with very limited mucosal incision is associated with minimal morbidity and preserves nasal function. Conservative and minimal invasive approach could be achieved early during learning curve. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pituitary%20surgery" title="pituitary surgery">pituitary surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=minimal%20invasive%20surgery" title=" minimal invasive surgery"> minimal invasive surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20curve" title=" learning curve"> learning curve</a>, <a href="https://publications.waset.org/abstracts/search?q=pituitary%20tumours" title=" pituitary tumours"> pituitary tumours</a>, <a href="https://publications.waset.org/abstracts/search?q=skull%20base%20surgery" title=" skull base surgery"> skull base surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20surgery" title=" endoscopic surgery"> endoscopic surgery</a> </p> <a href="https://publications.waset.org/abstracts/158508/endoscopic-pituitary-surgery-learning-curve-and-nasal-quality-of-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158508.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">124</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">9080</span> Endoscopic Ultrasound-Guided Choledochoduodenostomy in an Advanced Extrahepatic Cholangiocarcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diego%20Carrasco">Diego Carrasco</a>, <a href="https://publications.waset.org/abstracts/search?q=Catarina%20Freitas"> Catarina Freitas</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Rio%20Tinto"> Hugo Rio Tinto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Rio%20Tinto"> Ricardo Rio Tinto</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuno%20Couto"> Nuno Couto</a>, <a href="https://publications.waset.org/abstracts/search?q=Joaquim%20Gago"> Joaquim Gago</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Carvalho"> Carlos Carvalho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CD) to drain the gallbladder can be a palliative care procedure for non-surgical oncologic patients with cholelithiasis and cholangitis process. Case description: A 59-years old Caucasian male diagnosed with extrahepatic cholangiocarcinoma with multiple liver, lung and peritoneum metastasis, unresponsive to treatment with gemcitabine/cisplatin, presented in the institution with fever, hypotension, and severe upper right abdominal pain secondary to cholelithiasis and cholangitis process. The patient was admitted and started on large spectrum antibiotics plus fluid-challenge. Afterward, a percutaneous transhepatic biliary drainage (PTBD) was performed to drain the gallbladder. This procedure temporarily stabilized the patient. However, the definitive solution required gallbladder removal. Since the patient exhibited an advanced oncologic disease and poor response to the chemotherapy, he was not a candidate for surgical intervention. Diagnostic Pathways: A self-expanding metal stent was placed from the duodenum into the bile duct by endoscopic ultrasound-guided. The stent allowed efficient drainage of the contrast from the gallbladder at the end of the endoscopic procedure. Conclusion and Discussion: The stent allowed efficient drainage of the contrast from the gallbladder at the end of the endoscopic procedure and successfully reversed the cholangitis process. EUS-CD is an effective and safe technique and can be used as a palliative care procedure for non-surgical oncologic patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palliative%20care" title="palliative care">palliative care</a>, <a href="https://publications.waset.org/abstracts/search?q=cholangiocarcinoma" title=" cholangiocarcinoma"> cholangiocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=choledochoduodenostomy" title=" choledochoduodenostomy"> choledochoduodenostomy</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20ultrasound-guided" title=" endoscopic ultrasound-guided"> endoscopic ultrasound-guided</a> </p> <a href="https://publications.waset.org/abstracts/140682/endoscopic-ultrasound-guided-choledochoduodenostomy-in-an-advanced-extrahepatic-cholangiocarcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140682.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">185</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">9079</span> Bone Marrow Edema Syndrome in the Foot and Ankle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Alireza%20Mirghasemi">S.

Symptom onset may include sudden or gradual swelling and pain at rest or during activity, usually at night. This syndrome mostly affects middle-aged men and younger women who have pain in the lower extremities. The most common sites involved with BMES, in decreasing order of frequency, are the bones about the hip, knee, ankle, and foot. The diagnosis of BMES is made with magnetic resonance imaging to exclude other causes of bone marrow edema. The correct diagnosis often is delayed because of the low prevalence and nonspecific signs in the foot and ankle. This delay may intensify bone pain and impair patient function and quality of life. The goal of BMES treatment is to relieve pain and shorten disease duration. Treatment options are limited and may include symptomatic treatment, pharmacologic treatment, and surgery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transient%20osteoporosis" title="transient osteoporosis">transient osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20marrow%20edema%20syndrome" title=" bone marrow edema syndrome"> bone marrow edema syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=iloprost" title=" iloprost"> iloprost</a>, <a href="https://publications.waset.org/abstracts/search?q=bisphosphonates" title=" bisphosphonates"> bisphosphonates</a> </p> <a href="https://publications.waset.org/abstracts/34783/bone-marrow-edema-syndrome-in-the-foot-and-ankle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34783.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">362</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">9078</span> The OverStitch and OverStitch SX Endoscopic Suturing System in Bariatric Surgery, Closing Perforations and Fistulas and Revision Procedures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Tayefeh%20Norooz">Mohammad Tayefeh Norooz</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirhossein%20Kargarzadeh"> Amirhossein Kargarzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Overweight and obesity as an abnormality are health threatening factors. Body mass index (BMI) above 25 is referred to as overweight and above 30 as obese. Apollo Endosurgery, Inc., a pioneering company in endoscopy surgeries, is poised to revolutionize patient care with its minimally invasive treatment options. Some product solutions are designed to improve patient outcomes and redefine the future of healthcare. Weight gain post-weight-loss surgery may stem from an enlarged stomach opening, reducing fullness and increasing food intake. Apollo Endosurgery's OverStitch system, a minimally invasive approach, addresses this by using sutures to reduce stomach opening size. This reflects Apollo's commitment to transformative improvements in healing endoscopy, emphasizing a shift towards minimally invasive options. The system's versatility and precision in full-thickness suturing offer treatment alternatives, exemplified in applications like Endoscopic Sleeve Gastroplasty for reshaping obesity management. Apollo’s dedication to pioneering advancements suggests ongoing breakthroughs in minimally invasive surgery, positioning the OverStitch systems as a testament to innovation in patient care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apollo%20endosurgery" title="apollo endosurgery">apollo endosurgery</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopic%20sleeve%20gastroplasty" title=" endoscopic sleeve gastroplasty"> endoscopic sleeve gastroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20loss%20system" title=" weight loss system"> weight loss system</a>, <a href="https://publications.waset.org/abstracts/search?q=overstitch%20endoscopic%20suturing%20system" title=" overstitch endoscopic suturing system"> overstitch endoscopic suturing system</a>, <a href="https://publications.waset.org/abstracts/search?q=therapeutic" title=" therapeutic"> therapeutic</a>, <a href="https://publications.waset.org/abstracts/search?q=perforations" title=" perforations"> perforations</a>, <a href="https://publications.waset.org/abstracts/search?q=fistula" title=" fistula"> fistula</a> </p> <a href="https://publications.waset.org/abstracts/184878/the-overstitch-and-overstitch-sx-endoscopic-suturing-system-in-bariatric-surgery-closing-perforations-and-fistulas-and-revision-procedures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184878.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">62</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">9077</span> Gastrointestinal Disturbances in Postural Orthostatic Tachycardia Syndrome (POTS)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chandralekha%20Ashangari">Chandralekha Ashangari</a>, <a href="https://publications.waset.org/abstracts/search?q=Amer%20Suleman"> Amer Suleman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Purpose: The Postural Orthostatic Tachycardia Syndrome (POTS) affects primarily young women. POTS is a form of dysautonomia that is estimated to impact between 1,000,000 and 3,000,000 Americans, and millions more around the world. POTS is a form of orthostatic intolerance that is associated with many Gastrointestinal disturbances. The aim of this study is to determine the Gastrointestinal disturbances in Postural Orthostatic Tachycardia Syndrome (POTS) patients.2. Methods: 249 patients referred to our clinic from January to November with POTS. Reviewed the medical records of 249 POTS patients and gastrointestinal symptoms. Results: however out of 249 patients, 226 patients are female (90.76%; average age 32.69), 23 patients are male (9.24%; average age 27.91) Data analysis: Out of 249 patients 189 patients (76%) had vomiting or nausea, 150 patients (60%) had irritable bowel syndrome, 128 patients (51%) had bloating, 125 patients (50%) had constipation , 80 patients (32%) had abdominal pain, 56 patients (22%) had delayed gastric emptying, 24 patients (10%) had lactose intolerance, 8 patients (3%) had Gastroesophageal reflux disease, 5 patients (2%) had Iron deficiency anemia, 6 patients (2%) had Peptic ulcer disease, 4 patients (2%) had Celiac Disease. Conclusion: Patients with POTS have a very high prevalence of gastrointestinal symptoms however the majority of abnormalities appear to be motility related. Motility testing should be performed be performed in POTS patients. The diagnostic yield of endoscopic procedures appears to be low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gastrointestinal%20disturbances" title="gastrointestinal disturbances">gastrointestinal disturbances</a>, <a href="https://publications.waset.org/abstracts/search?q=Postural%20Orthostatic%20Tachycardia%20Syndrome%20%28POTS%29" title=" Postural Orthostatic Tachycardia Syndrome (POTS)"> Postural Orthostatic Tachycardia Syndrome (POTS)</a>, <a href="https://publications.waset.org/abstracts/search?q=celiac%20disease" title=" celiac disease"> celiac disease</a>, <a href="https://publications.waset.org/abstracts/search?q=POTS%20patients" title=" POTS patients"> POTS patients</a> </p> <a href="https://publications.waset.org/abstracts/25781/gastrointestinal-disturbances-in-postural-orthostatic-tachycardia-syndrome-pots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25781.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">338</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">9076</span> Prediction of the Heat Transfer Characteristics of Tunnel Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung%20Cho%20Yang">Seung Cho Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Sung%20Lee"> Jae Sung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Se%20Hee%20Park"> Se Hee Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study suggests the analysis method to predict the damages of tunnel concrete caused by fires.

But employers are able to make the right decisions so that the tunnel is guided with the highest precision if they consider some points. We are investigating two tunnels with lengths of 12 and 18 kilometers that were dug by Tunnel boring machine machines to transfer water, how the contractor’s decision to control the 12 kilometer tunnel caused the most accuracy of one centimeter to the next part of the tunnel will be connected. We will also investigate the reasons for the deviation of axis in the 18 km tunnel about 20 meters. Also we review the calculations of surveyor engineers in both tunnels and what challenges there will be in the calculations and teach how to solve these challenges.

Ergonomics is the study of how working conditions, machines and equipment can be arranged in order that people can work with them more efficiently. In this research communication an attempt has been made to study the effect of hand-arm vibrational exposure on the workers of a gear manufacturing plant by comparison of potential Carpal Tunnel Syndrome (CTS) symptoms and effect of different exposure levels of vibration on occurrence of CTS in actual industrial environment. Chi square test and correlation analysis have been considered for statistical analysis. From Chi square test, it has been found that the potential CTS symptoms occurrence is significantly dependent on the level of vibrational exposure. Data analysis indicates that 40.51% workers having potential CTS symptoms are exposed to vibration. Correlation analysis reveals that potential CTS symptoms are significantly correlated with exposure to level of vibration from handheld tools and to repetitive wrist movements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CTS%20symptoms" title="CTS symptoms">CTS symptoms</a>, <a href="https://publications.waset.org/abstracts/search?q=hand-arm%20vibration" title=" hand-arm vibration"> hand-arm vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title=" ergonomics"> ergonomics</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20tests" title=" physical tests"> physical tests</a> </p> <a href="https://publications.waset.org/abstracts/38245/ergonomical-study-of-hand-arm-vibrational-exposure-in-a-gear-manufacturing-plant-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38245.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">371</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">9073</span> Groundwater Seepage Estimation into Amirkabir Tunnel Using Analytical Methods and DEM and SGR Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Farhadian">Hadi Farhadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Homayoon%20Katibeh"> Homayoon Katibeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, groundwater seepage into Amirkabir tunnel has been estimated using analytical and numerical methods for 14 different sections of the tunnel.

Here, first consideration is the optimum piston weight. Although various aspects of the influence of piston weight on gun tunnel performance have been studied, it is not possible to decide from the existing literature what piston weight is required for optimum performance in various conditions. The technique whereby the piston is rapidly brought to rest at the end of the gun tunnel barrel, and the resulted peak pressure is equal in magnitude to the final equilibrium pressure, is called the equilibrium piston technique. The equilibrium piston technique was developed to estimate the equilibrium piston mass; but this technique cannot give an appropriate estimate for the optimum piston weight. In the present work, a gun tunnel with diameter of 3 in. is described and its performance is investigated numerically to obtain the effect of piston and its weight. Numerical results in the present work are in very good agreement with experimental results. Significant influence of the existence of a piston is shown by comparing the gun tunnel results with results of a conventional shock tunnel in the same dimension and same initial condition. In gun tunnel, an increase of around 250% in running time is gained relative to shock tunnel. Also, Numerical results show that equilibrium piston technique is not a good way to estimate suitable piston weight and there will be a lighter piston which can increase running time of the gun tunnel around 60%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gun%20tunnel" title="gun tunnel">gun tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersonic%20flow" title=" hypersonic flow"> hypersonic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=piston" title=" piston"> piston</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20tunnel" title=" shock tunnel"> shock tunnel</a> </p> <a href="https://publications.waset.org/abstracts/37641/effect-of-piston-and-its-weight-on-the-performance-of-a-gun-tunnel-via-computational-fluid-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37641.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">373</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">9071</span> Aerodynamic Analysis of Vehicles in the Wind Tunnel and Water Tunnel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elmo%20Thiago%20Lins%20C%C3%B6uras%20Ford">Elmo Thiago Lins Cöuras Ford</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Alessandra%20Carvalho%20do%20Vale"> Valentina Alessandra Carvalho do Vale</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The simulation in wind tunnel is used thoroughly to model real situations of drainages of air.

This work had the objective of visualizing the characteristics aerodynamics of two automobiles in different ways. To accomplish that drainage of air a fan that generated a speed exists (measured with anemometer of hot thread) of 4,1m/s and 4,95m/s. To visualize the path of the air through the cars, in the wind tunnel, smoke was used, obtained with it burns of vegetable oil. For “to do smoke” vegetable oil was used, that was burned for a tension of 20 V generated by a thread of 2,5 mm. The cars were placed inside of the wind tunnel with the drainage of “air-smoke” and photographed, registering like this the path lines around them, in the 3 different speeds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20drag" title=" vehicle drag"> vehicle drag</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetable%20oil" title=" vegetable oil"> vegetable oil</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title=" wind tunnel "> wind tunnel </a> </p> <a href="https://publications.waset.org/abstracts/18356/aerodynamic-analysis-of-vehicles-in-the-wind-tunnel-and-water-tunnel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18356.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">602</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">9070</span> Food Bolus Obstruction: A Rural Hospital’s Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davina%20Von%20Hagt">Davina Von Hagt</a>, <a href="https://publications.waset.org/abstracts/search?q=Genevieve%20Gibbons"> Genevieve Gibbons</a>, <a href="https://publications.waset.org/abstracts/search?q=Matt%20Henderson"> Matt Henderson</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20Bowles"> Tom Bowles</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: Food bolus obstructions are common emergency surgical presentations, but there is no established management guideline in a rural setting. Intervention usually involves endoscopic removal after initial medical management has failed. Within a rural setting, this falls upon the general surgeon. There are varied endoscopic techniques that may be used. Methodology: A review of the past fifty cases of food bolus obstruction managed at Albany Health Campus was retrospectively reviewed to assess endoscopic findings and techniques. Operation notes, histopathology, imaging, and patient notes were reviewed. Results: 50 patients underwent gastroscopy for food bolus obstruction from August 2017 to March 2021. Ages ranged from 11 months to 95 years, with the majority of patients aged between 30-70 years. 88% of patients were male. Meat was the most common bolus (20% unspecified, 20% steak, 10% chicken, 6% lamb, 4% sausage, 2% pork). At endoscopy, 12% were found not to have a food bolus obstruction. Two patients were found to have oesophageal cancer, and four patients had a stricture and required dilatation. A variety of methods were used to relieve oesophageal obstruction ranging from pushing through to stomach (24 patients), using an overtube (10 patients), raptor (13 patients), and less common instruments such as Roth net, basket, guidewire, and pronged grasper. One patient had an unsuccessful endoscopic retrieval and required theatre for laparoscopic assisted removal with rendezvous endoscopic piecemeal removal via oesophagus and gastrostomy. Conclusion: Food bolus obstruction is a common emergency presentation. Within the rural setting, management requires innovation and teamwork within the safety of the local experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20bolus%20obstruction" title="food bolus obstruction">food bolus obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20hospital" title=" regional hospital"> regional hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20management" title=" surgical management"> surgical management</a>, <a href="https://publications.waset.org/abstracts/search?q=innovative%20surgical%20treatment" title=" innovative surgical treatment"> innovative surgical treatment</a> </p> <a href="https://publications.waset.org/abstracts/140739/food-bolus-obstruction-a-rural-hospitals-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140739.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">267</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">9069</span> Endoscopic Stenting of the Main Pancreatic Duct in Patients With Pancreatic Fluid Collections After Pancreas Transplantation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Teterin">Y.

Yartcev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: One of the most common complications after pancreas transplantation are pancreatic fluid collections (PFCs), which are often complicated not only by infection and subsequent disfunction of the pancreatoduodenal graft (PDG), but also with a rather high mortality rate of recipients. Drainage is not always effective and often requires repeated open surgical interventions, which worsens the outcome of the surgery. Percutaneous drainage of PFCs combined with endoscopic stenting of the main pancreatic duct of the pancreatoduodenal graft (MPDPDG) showed high efficiency in the treatment of PFCs. Aims & Methods: From 01.01.2012 to 31.12.2021 at the Sklifosovsky Research Institute for Emergency Medicine were performed 64 transplantations of PDG. In 11 cases (17.2%), the early postoperative period was complicated by the formation of PFCs. Of these, 7 patients underwent percutaneous drainage of pancreonecrosis with high efficiency and did not required additional methods of treatment. In the remaining 4 patients, drainage was ineffective and was an indication for endoscopic stenting of the MPDPDG. They were the ones who made up the study group. Among them were 3 men and 1 woman. The mean age of the patients was 36,4 years.PFCs in these patients formed on days 1, 12, 18, and 47 after PDG transplantation. We used a gastroscope to stent the MPDPDG, due to anatomical features of the location of the duodenoduodenal anastomosis after PDG transplantation. Through the endoscope channel was performed selective catheterization of the MPDPDG, using a catheter and a guidewire, followed by its contrasting with a water-soluble contrast agent. Due to the extravasation of the contrast, was determined the localization of the defect in the PDG duct system. After that, a plastic pancreatic stent with a diameter of 7 Fr. and a length of 7 cm. was installed along guidewire. The stent was installed in such a way that its proximal edge completely covered the defect zone, and the distal one was determined in the intestinal lumen. Results: In all patients PDG pancreaticography revealed extravasation of a contrast in the area of the isthmus and body of the pancreas, which required stenting of the MPDPDG. In 1 (25%) case, the patient had a dislocation of the stent into the intestinal lumen (III degree according to Clavien-Dindo (2009)). This patient underwent repeated endoscopic stenting of the MPDPDG. On average 23 days after endoscopic stenting of the MPDPDG, the drainage tubes were removed and after approximately 40 days all patients were discharged in a satisfactory condition with follow-up endocrinologist and surgeon consultation. Pancreatic stents were removed after 6 months ± 7 days. Conclusion: Endoscopic stenting of the main pancreatic duct of the donor pancreas is by far the most highly effective and minimally invasive method in the treatment of PFCs after transplantation of the pancreatoduodenal complex. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pancreas%20transplantation" title="pancreas transplantation">pancreas transplantation</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopy%20surgery" title=" endoscopy surgery"> endoscopy surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=stenting" title=" stenting"> stenting</a>, <a href="https://publications.waset.org/abstracts/search?q=main%20pancreatic%20duct" title=" main pancreatic duct"> main pancreatic duct</a> </p> <a href="https://publications.waset.org/abstracts/159256/endoscopic-stenting-of-the-main-pancreatic-duct-in-patients-with-pancreatic-fluid-collections-after-pancreas-transplantation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159256.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">9068</span> Nutrient Foramina of the Lunate Bone of the Hand – an Anatomical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.J.%20Jiji">P.J.

The dislocation can interrupt the vasculature and would cause avascular necrosis. The objective of the present study was to study the morphology and number of the nutrient foramina in the cadaveric dried lunate bones of the Indian population. Methods: The present study included 28 lunate bones (13 right sided and 15 left sided) which were obtained from the gross anatomy laboratory of our institution. The bones were macroscopically observed for the nutrient foramina and the data was collected with respect to their number. The tabulation of the data and analysis were done. Results: All of our specimens (100%) exhibited the nutrient foramina over the non-articular surfaces. The foramina were observed only over the palmar and dorsal surfaces of the lunate bones. The foramen ranged between 2 and 10. The foramina were more in number over the dorsal surface (average number 3.3) in comparison to the palmar surface (average number 2.4). Conclusion: We believe that the present study has provided important data about the nutrient foramina of the lunate bones. The data is enlightening to the orthopedic surgeon and would help in the hand surgeries. The morphological knowledge of the vasculature, their foramina of entry and their number is required to understand the concepts in the lunatomalacia and Kienbock’s disease. <p
