The purpose of the research was to study the association between UP width and surgical outcomes after distal hypospadias repair in children. Materials and methods: The study included 138 patients with distal hypospadias. The mean age at the time of surgery was 4.6 years (6 months – 16 years). We measured UP width at the “midpoint within the glans” and used the HOSE scale to assess postoperative outcomes. The patients were divided into 2 groups: group 1 – the patients (107) with UP < 8mm, group 2 – patients (31) with UP > 8mm. All boys underwent TIP repair. Preincision means UP width after incision means UP width, and the UP ratio was analyzed. Statistical data were obtained using Statistica 10. Results: The findings were preincision mean UP width - 5.4 mm and 9.4 mm; after incision mean UP width - 13mm and 17.5 mm; UP ratio - 0.41 and 0.53 in group 1 and group 2, respectively. Most postoperative complications (fistula, meatal stenosis, and stricture) happened in patients with UP width < 8 mm versus ≥ 8 mm (7/107 versus 2/31, respectively). HOSE results were 15.77 (group 1), 15.65 (group 2). The follow up lasted up to 12 months. Statistical analysis proved the absence of correlation between UP width and postoperative complications. Conclusions: In conclusion, it should be noted that the success of surgical repair mostly depended on the surgical technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=distal%20hypospadias" title=" distal hypospadias"> distal hypospadias</a>, <a href="https://publications.waset.org/abstracts/search?q=tip%20repair" title=" tip repair"> tip repair</a>, <a href="https://publications.waset.org/abstracts/search?q=urethral%20plate%20width" title=" urethral plate width"> urethral plate width</a> </p> <a href="https://publications.waset.org/abstracts/149424/the-impact-of-urethral-plate-width-on-surgical-outcomes-after-distal-hypospadias-repair-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149424.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">123</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">1366</span> Strategy and Coarctation of the Aorta Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shirin%20Jalili">Shirin Jalili</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Ghasemi%20Shayan"> Ramin Ghasemi Shayan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coarctation of the aorta (CoA) may be a common (CHD), which is the seventh most common sort of CHD. Still, this is often likely a think little off since the determination may be deferred, indeed within the pediatric populace. The choice for surgical repair incorporates resection of the contracted section with end-to-end or end-to-side anastomosis, subclavian fold aortoplasty, resection, and join the intervention, or prosthetic fix aortoplasty. Drastically expanded end-to-end repair or switched subclavian fold aortoplasty can be utilized when the coarctation expands to the distal arch. Swell angioplasty can be a palliative choice sometime recently the conclusive redress. Its objective is to stabilize high-risk patients that cannot be submitted to quick surgical intercession, such as untimely newborns. For disconnected and discrete coarctations, it can, as a rule, be drawn nearer and repaired by means of cleared out thoracotomy, extraction of the infected aorta (coarctectomy), and remaking, ordinarily by amplified end-to-end anastomosis. In this article, we need to supply a diagram of current proposals and strategies utilized to picture coarctations of the aorta. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coarctation%20of%20the%20aorta" title="coarctation of the aorta">coarctation of the aorta</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20heart%20disease" title=" congenital heart disease"> congenital heart disease</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20repair" title=" surgical repair"> surgical repair</a> </p> <a href="https://publications.waset.org/abstracts/144382/strategy-and-coarctation-of-the-aorta-repair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144382.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">164</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">1365</span> Optimal Replacement Period for a One-Unit System with Double Repair Cost Limits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min-Tsai%20Lai">Min-Tsai Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Taqwa%20Hariguna"> Taqwa Hariguna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a periodical replacement model for a system, considering the concept of single and cumulative repair cost limits simultaneously.

When a minor failure occurs, if the repair cost is less than a single repair cost limit L1 and the accumulated repair cost is less than a cumulative repair cost limit L2, then minimal repair is executed, otherwise, the system is preventively replaced. The system is also replaced at time T or at serious failure. The optimal period T minimizing the long-run expected cost per unit time is verified to be finite and unique under some specific conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=repair-cost%20limit" title="repair-cost limit">repair-cost limit</a>, <a href="https://publications.waset.org/abstracts/search?q=cumulative%20repair-cost%20limit" title=" cumulative repair-cost limit"> cumulative repair-cost limit</a>, <a href="https://publications.waset.org/abstracts/search?q=minimal%20repair" title=" minimal repair"> minimal repair</a>, <a href="https://publications.waset.org/abstracts/search?q=periodical%20replacement%20policy" title=" periodical replacement policy"> periodical replacement policy</a> </p> <a href="https://publications.waset.org/abstracts/28802/optimal-replacement-period-for-a-one-unit-system-with-double-repair-cost-limits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28802.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">365</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">1364</span> Good Functional Outcome after Late Surgical Treatment for Traumatic Rotator Cuff Tear, a Retrospective Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheila%20Zhaeentan">Soheila Zhaeentan</a>, <a href="https://publications.waset.org/abstracts/search?q=Anders%20Von%20Heijne"> Anders Von Heijne</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabet%20Hagert"> Elisabet Hagert</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20Stark"> André Stark</a>, <a href="https://publications.waset.org/abstracts/search?q=Bj%C3%B6rn%20Salomonsson"> Björn Salomonsson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recommended treatment for traumatic rotator cuff tear (TRCT) is surgery within a few weeks after injury if the diagnosis is made early, especially if a functional impairment of the shoulder exists. This may lead to the assumption that a poor outcome then can be expected in delayed surgical treatment, when the patient is diagnosed at a later stage. The aim of this study was to investigate if a surgical repair later than three months after injury may result in successful outcomes and patient satisfaction. There is evidence in literature that good results of treatment can be expected up to three months after the injury, but little is known of later treatment with cuff repair. 73 patients (75 shoulders), 58 males/17 females, mean age 59 (range 34-‐72), who had undergone surgical intervention for TRCT between January 1999 to December 2011 at our clinic, were included in this study. Patients were assessed by MRI investigation, clinical examination, Western Ontario Rotator Cuff index (WORC), Oxford Shoulder Score, Constant-‐Murley Score, EQ-‐5D and patient subjective satisfaction at follow-‐up. The patients treated surgically within three months ( < 12 weeks) after injury (39 cases) were compared with patients treated more than three months ( ≥ 12 weeks) after injury (36 cases). WORC was used as the primary outcome measure and the other variables as secondary. A senior consultant radiologist, blinded to patient category and clinical outcome, evaluated all MRI-‐images. Rotator cuff integrity, presence of arthritis, fatty degeneration and muscle atrophy was evaluated in all cases. The average follow-‐up time was 56 months (range 14-‐149) and the average time from injury to repair was 16 weeks (range 3-‐104). No statistically significant differences were found for any of the assessed parameters or scores between the two groups. The mean WORC score was 77 (early group, range 25-‐ 100 and late group, range 27-‐100) for both groups (p= 0.86), Constant-‐Murley Score (p= 0.91), Oxford Shoulder Score (p= 0.79), EQ-‐5D index (p= 0.86). Re-‐tear frequency was 24% for both groups, and the patients with re-‐tear reported less satisfaction with outcome. Discussion and conclusion: This study shows that surgical repair of TRCT performed later than three months after injury may result in good functional outcomes and patient satisfaction. However, this does not motivate an intentional delay in surgery when there is an indication for surgical repair as that delay may adversely affect the possibility to perform a repair. Our results show that surgeons may safely consider surgical repair even if a delay in diagnosis has occurred. A retrospective cohort study on 75 shoulders shows good functional result after traumatic rotator cuff tear (TRCT) treated surgically up to one year after the injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traumatic%20rotator%20cuff%20injury" title="traumatic rotator cuff injury">traumatic rotator cuff injury</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20to%20surgery" title=" time to surgery"> time to surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20outcome" title=" surgical outcome"> surgical outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=retrospective%20cohort%20study" title=" retrospective cohort study"> retrospective cohort study</a> </p> <a href="https://publications.waset.org/abstracts/6140/good-functional-outcome-after-late-surgical-treatment-for-traumatic-rotator-cuff-tear-a-retrospective-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6140.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">223</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">1363</span> Case Study on the Effects of Early Mobilization in the Post-Surgical Recovery of Athletes with Open Triangular Fibrocartilage Complex Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blair%20Arthur%20Agero%20Jr.">Blair Arthur Agero Jr.</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucia%20Garcia%20Heras"> Lucia Garcia Heras</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The triangular fibrocartilage complex (TFCC) is one of the crucial stabilizing ligaments of the wrist. The TFCC is also subject to excessive stress amongst performance athletes and enthusiasts. The excessive loading of the TFCC may lead to a partial or complete rupture that requires surgery. The recovery from an open TFCC surgical repair may take several months. Immobilization of the repaired wrist for a given period is part of all the current protocols in the post-surgical treatment. The immobilization to prevent the rotation of the forearm can last from six weeks to eight weeks with the wrist held in a neutral position. In all protocols reviewed, the pronosupination is only initiated between the 6th week and 8th week or even later after the cast is removed. The prolonged immobilization can cause stiffness of the wrist and hand. Furthermore, the entire period of post-surgical hand therapy has its economic impact, especially for performing athletes. However, delayed mobilization, specifically rotation of the wrist, is necessary to allow ligament healing. This study aims to report the effects of early mobilization of the wrist in athletes who had an open surgical repair of the TFCC. The surgery was done by the co-author, and the hand therapy was implemented by the main author. The cases documented spans from 2014 to 2019 and were all performed in Dubai, United Arab Emirates. All selected participants in this case study were provided with a follow-up questionnaire to ascertain their current condition since their surgery. The respondents reported high satisfaction in the results of their treatment and have verified zero re-rupture of their TFCC despite mobilizing and rotating the wrist at the third-week post-surgery during their hand therapy. There is also a negligible number of respondents who reported a limitation in their ranges of pronosupination. This case study suggests that early mobilization of the wrist after an open TFCC surgical repair can be more beneficial to the patient as opposed to the traditional treatment of prolonged immobilization. However, it should be considered that the patients selected in this case study are professional performance athletes and advanced fitness enthusiasts. Athletes are known to withstand vigorous physical stress in their training that may correlate to their ability to better cope with the progressive stress that was implemented during their hand therapy. Nevertheless, this approach has its merits, and application of it may be adjusted for patients with a similar injury and surgical procedure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand%20therapy" title="hand therapy">hand therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20athlete" title=" performance athlete"> performance athlete</a>, <a href="https://publications.waset.org/abstracts/search?q=TFCC%20repair" title=" TFCC repair"> TFCC repair</a>, <a href="https://publications.waset.org/abstracts/search?q=wrist%20ligament" title=" wrist ligament"> wrist ligament</a> </p> <a href="https://publications.waset.org/abstracts/122537/case-study-on-the-effects-of-early-mobilization-in-the-post-surgical-recovery-of-athletes-with-open-triangular-fibrocartilage-complex-repair" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122537.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">150</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">1362</span> Comparative Study of Outcomes of Nonfixation of Mesh versus Fixation in Laparoscopic Total Extra Peritoneal (TEP) Repair of Inguinal Hernia: A Prospective Randomized Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raman%20Sharma">Raman Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Jain"> S. K. Jain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aims and Objectives: Fixation of the mesh during laparoscopic total extraperitoneal (TEP) repair of inguinal hernia is thought to be necessary to prevent recurrence. However, mesh fixation may increase surgical complications and postoperative pain. Our objective was to compare the outcomes of nonfixation with fixation of polypropylene mesh by metal tacks during TEP repair of inguinal hernia. Methods: Forty patients aged 18 to72 years with inguinal hernia were included who underwent laparoscopic TEP repair of inguinal hernia with (n=20) or without (n=20) fixation of the mesh. The outcomes were operative duration, postoperative pain score, cost, in-hospital stay, time to return to normal activity, and complications. Results: Patients in whom the mesh was not fixed had shorter mean operating time (p < 0.05). We found no difference between groups in the postoperative pain score, incidence of recurrence, in-hospital stay, time to return to normal activity and complications (P > 0.05). Moreover, a net cost savings was realized for each hernia repair performed without stapled mesh. Conclusions: TEP repair without mesh fixation resulted in the shorter operating time and lower operative cost with no difference between groups in the postoperative pain score, incidence of recurrence, in-hospital stay, time to return to normal activity and complications. All this contribute to make TEP repair without mesh fixation a better choice for repair of uncomplicated inguinal hernia, especially in developing nations with scarce resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=postoperative%20pain%20score" title="postoperative pain score">postoperative pain score</a>, <a href="https://publications.waset.org/abstracts/search?q=inguinal%20hernia" title=" inguinal hernia"> inguinal hernia</a>, <a href="https://publications.waset.org/abstracts/search?q=nonfixation%20of%20mesh" title=" nonfixation of mesh"> nonfixation of mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20extra%20peritoneal%20%28TEP%29" title=" total extra peritoneal (TEP)"> total extra peritoneal (TEP)</a> </p> <a href="https://publications.waset.org/abstracts/36490/comparative-study-of-outcomes-of-nonfixation-of-mesh-versus-fixation-in-laparoscopic-total-extra-peritoneal-tep-repair-of-inguinal-hernia-a-prospective-randomized-controlled-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36490.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">343</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">1361</span> Surgical Skills in Mulanje</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nick%20Toossi">Nick Toossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Hartland"> Joseph Hartland</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Malawi is an example of a low resource setting which faces a chronic shortage of doctors and other medical staff. This shortfall is made up for by clinical officers (COs), who are para-medicals trained for 4 years. The literature suggests to improve outcomes surgical skills training specifically should be promoted for COs in district and mission hospitals. Accordingly, the primary author was tasked with developing a basic surgical skills teaching package for COs of Mulanje Mission Hospital (MMH), Malawi, as part of a 4th year medical student External Student Selected Component field trip. MMH is a hospital based in the South of Malawi near the base of Mulanje Mountain and works in an extremely isolated environment with some of the poorest communities in the country. Traveling to Malawi the medical student author performed an educational needs assessment to develop and deliver a bespoke basic surgical skills teaching package. Methodology: An initial needs assessment identified the following domains: basic surgical skills (instrument naming & handling, knot tying, suturing principles and suturing techniques) and perineal repair. Five COs took part in a teaching package involving an interactive group simulation session, overseen by senior clinical officers and surgical trainees from the UK. Non-organic and animal models were used for simulation practice. This included the use of surgical skills boards to practice knot tying and ox tongue to simulate perineal repair. All participants spoke and read English. The impact of the session was analysed in two different ways. The first was via a pre and post Single Best Answer test and the second a questionnaire including likert’s scales and free text response questions. Results: There was a positive trend in pre and post test scores on competition of the course. There was increase in the mean confidence of learners before and after the delivery of teaching in basic surgical skills and simulated perineal repair, especially in ‘instrument naming and handling’. Whilst positively received it was discovered that learners desire more frequent surgical skills teaching sessions in order to improve and revise skills. Feedback suggests that the learners were not confident in retaining the skills without regular input. Discussion: Skills and confidence were improved as a result of the teaching provided. Learner's written feedback suggested there was an overall appetite for regular surgical skills teaching in the clinical environment and further opportunities to allow for deliberate self-practice. Surgical mentorship schemes facilitating supervised theatre time among trainees and lead surgeons along with improving access to surgical models/textbooks were some of the simple suggestions to improve surgical skills and confidence among COs. Although, this study is limited by population size it is reflective of the small, isolated and low resource environment in which this healthcare is delivered. This project does suggest that current surgical skills packages used in the UK could be adapted for employment in low resource settings, but it is consistency and sustainability that staff seek above all in their on-going education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clinical%20officers" title="clinical officers">clinical officers</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=Malawi" title=" Malawi"> Malawi</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20skills" title=" surgical skills"> surgical skills</a> </p> <a href="https://publications.waset.org/abstracts/79550/surgical-skills-in-mulanje" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79550.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">183</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">1360</span> Anal Repair and Diamond Flap in Moderate Anal Stenosis Patient After an Open Hemorrhoidectomy Surgery: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andriana%20Purnama">Andriana Purnama</a>, <a href="https://publications.waset.org/abstracts/search?q=Reno%20Rudiman"> Reno Rudiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Kezia%20Christy"> Kezia Christy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anal stenosis which develops due to anoderm scarring usually caused by secondary to surgical trauma, has become common, causing significant decrease patient’s quality of life. Even though mild anal stenosis was treated with non-surgical treatment, but surgical reconstruction in unavoidable for moderate to severe anal stenosis that cause distressing, severe anal pain and inability to defecate. In our study, we intend to share our result with the use of diamond flap in treatment of anal stenosis. This case report illustrates a 57-year-old male patient who presented with difficulty and discomfort in defecation caused by anal stenosis after 2 years of open hemorrhoidectomy surgery. At physical examination, there was requirement of forceful dilatation when the index finger was inserted or precisely 6mm as measured by hegar dilator (moderate anal stenosis). Blood test result was within normal limits. The patient underwent anal repair and diamond flap where the scar tissue at 6 and 9 o’clock directions was excised and diamond graft was incised carefully while paying attention to the vascular supply. Finally, the graft was fixated without any tension to the anal canal, resulting in diameter of 2 cm after operation. After 2 days post operation, the patient was in stable condition, without any complication, and discharged. There was no abnormality concerning the stool. Ten days after the operation, diamond flap was in normal condition and without any complication. He was scheduled for futher follow up at the Digestive Surgery Department. Anal stenosis due to overzealous hemorrhoidectomy is a complication that is preventable when performed in experienced hands. Diamond flap was one of the options for the anal stenosis treatment with less complication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anal%20stenosis" title="anal stenosis">anal stenosis</a>, <a href="https://publications.waset.org/abstracts/search?q=diamond%20flap" title=" diamond flap"> diamond flap</a>, <a href="https://publications.waset.org/abstracts/search?q=post%20hemorrhoidectomy" title=" post hemorrhoidectomy"> post hemorrhoidectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=anal%20repair" title=" anal repair"> anal repair</a> </p> <a href="https://publications.waset.org/abstracts/159843/anal-repair-and-diamond-flap-in-moderate-anal-stenosis-patient-after-an-open-hemorrhoidectomy-surgery-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159843.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">92</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">1359</span> A Current Problem for Steel Bridges: Fatigue Assessment of Seams´ Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Pasternak">H.

In order to transfer them in their present conditions to the next generations, maintaining these historical structures are one of our main tasks. Seismic performance of historical structures damaged by the earthquake effects can be enhanced by repair and retrofitting applications. However, repair and retrofitting applications of historical structures are more complicated compared with the traditional structures. For this reason, they need much more attention in repair and retrofitting applications to preserve the spirit of historical structures.

During this period, we have constructed many structures like buildings, bridges, industrial structures, pavement, water tanks etc. using this construction material. These structures have been created with huge investment of resources. It is essential to maintain those structures in functional condition. Since deterioration in RCC Structures is a common and natural phenomenon it is required to have a detailed plan, methodology for structural repair and rehabilitation shall be in place for dealing such issues. It is important to know exact reason of distress, type of distress and correct method of repair concrete structures. The different methods of repair are described in paper according to distress category which can be refereed for repair. Major finding of the study is that to protect our structure we need to have maintenance frequency and correct material to be chosen for repair. Also workmanship during repair needs to be taken utmost care for quality repair. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deterioration" title="deterioration">deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20condition" title=" functional condition"> functional condition</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced%20cement%20concrete" title=" reinforced cement concrete"> reinforced cement concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a> </p> <a href="https://publications.waset.org/abstracts/41322/structural-rehabilitation-retrofitting-and-strengthening-of-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41322.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">253</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">1356</span> A Case Study on the Field Surveys and Repair of a Marine Approach-Bridge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20H.%20Park">S.

The oral and maxillofacial unit at the Royal Surrey Hospital is the tertiary referral center for maxillofacial trauma from five regional hospitals. This is a complete audit cycle of midface trauma referrals managed over a one year period. The standard set was that clinical assessment of the midface fracture would take place in a consultant led outpatient clinic within 7 days, and when indicated, surgical fixation would occur within 10 days of referral. Retrospective data was collected over one year (01/11/2018 - 31/12/2019). Three key changes were implemented: an IT referral mailbox, standardization of an on-call trauma table, and creation of a trauma theatre list. Re-audit was carried out over six months completing the cycle. 283 midface fracture referrals were received, of which 22 patients needed surgical fixation. The average time from referral to outpatient follow-up improved from 14.5 days to 8.3 days, and time from referral to surgery improved from 21.5 days to 11.6 days. Changes implemented in this audit significantly improved patient prioritization to appropriate outpatient clinics and shortened time to surgical intervention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maxillofacial%20trauma" title="maxillofacial trauma">maxillofacial trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=midface%20trauma" title=" midface trauma"> midface trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20and%20maxillofacial%20surgery" title=" oral and maxillofacial surgery"> oral and maxillofacial surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery%20fixation" title=" surgery fixation"> surgery fixation</a> </p> <a href="https://publications.waset.org/abstracts/131329/midface-trauma-outpatient-follow-up-and-surgical-treatment-times" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131329.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">143</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">1354</span> Assertion-Driven Test Repair Based on Priority Criteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruilian%20Zhao">Ruilian Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shukai%20Zhang"> Shukai Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Wang"> Yan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiwei%20Wang"> Weiwei Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Repairing broken test cases is an expensive and challenging task in evolving software systems. Although an automated repair technique with intent preservation has been proposed, but it does not take into account the association between test repairs and assertions, leading to a large number of irrelevant candidates and decreasing the repair capability. This paper proposes an assertion-driven test repair approach. Furthermore, an intent-oriented priority criterion is raised to guide the repair candidate generation, making the repairs closer to the intent of the test. In more detail, repair targets are determined through post-dominance relations between assertions and the methods that directly cause compilation errors. Then, test repairs are generated from the target in a bottom-up way, guided by the intent-oriented priority criteria. Finally, the generated repair candidates are prioritized to match the original test intent. The approach is implemented and evaluated on the benchmark of 4 open-source programs and 91 broken test cases. The result shows that the approach can fix 89% (81/91) of broken test cases, which is more effective than the existing intentpreserved test repair approach, and our intent-oriented priority criteria work well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=test%20repair" title="test repair">test repair</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20intent" title=" test intent"> test intent</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20test" title=" software test"> software test</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20case%20evolution" title=" test case evolution"> test case evolution</a> </p> <a href="https://publications.waset.org/abstracts/166462/assertion-driven-test-repair-based-on-priority-criteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166462.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">129</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">1353</span> Investigation into Black Oxide Coating of 410 Grade Surgical Stainless Steel Using Alkaline Bath Treatment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20K.%20Saju">K.

The aim of this study was to characterize morphological variability of the mitral valve leaflets and to provide the size of their particular parts. Materials and Methods: In the study, we included 200 autopsied human hearts from Caucasian individuals (25% females) with mean age 47.5 (±17.9) without any valvular diseases. The morphology of the mitral valve was evaluated. The intercommissural and aorto-mural diameters of the mitral annulus were measured. All leaflets and their scallops were identified. The base and the height of the posteromedial commissure (PM-C), anterolateral commissure (AL-C), anterior leaflet (AL) and posterior leaflet (PL) with their scallops were measured. Results: The intercommissural diameter was 28.0±4.8 mm, the aorto-mural diameter 19.7±4.8 mm, circumference of the mitral annulus 89.9±12.6 mm and the area of the mitral valve 485.4±171.4 mm2. Classical mitral valves (AL+AL-C+PL(P1,P2,P3)+PM-C) were found in 141 (70.5%) specimens. In classical type, the mean AL base and height were 30.8±4.9 mm and 20.6±4.2 mm, while mean PL base and height 45.1±8.2 mm 12.9±2.8 mm respectively. The mean ratio of the AL base to PL base was 0.7±0.2. Variations in PL were found in 55 (27.5%) and in AL in 5 (2.5%) hearts. The most common variations were: valve with one accessory scallop (AcS) between P3 and PM-C (7%); AcS between P1 and AL-C (4%); connections of P2 and P3 scallops (4%); connections of P1 and P2 scallops (3%); AcS in AL (2.5%). All AcS were smaller than the main PL scallops. The mean intertrigonal distance was 21.9±3.8 mm. Conclusions: In all cases, the mitral valve is built by two main leaflets with possible variants in secondary to leaflets scallops (29.5%). The variations are largely associated with PL and are mostly related to the presence of AcS. Anatomically the AL is not divided into scallops, and it occupies 34.5% of the mitral annulus circumference. Understanding the anatomy of the mitral valve leaflets helps to planning and performing mitral valve repair procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessory%20scallop" title="accessory scallop">accessory scallop</a>, <a href="https://publications.waset.org/abstracts/search?q=commissure" title=" commissure"> commissure</a>, <a href="https://publications.waset.org/abstracts/search?q=connected%20%20scallops" title=" connected scallops"> connected scallops</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20heart" title=" human heart"> human heart</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20leaflets" title=" mitral leaflets"> mitral leaflets</a>, <a href="https://publications.waset.org/abstracts/search?q=mitral%20valve" title=" mitral valve"> mitral valve</a> </p> <a href="https://publications.waset.org/abstracts/65755/anatomy-of-the-human-mitral-valve-leaflets-implications-for-transcatheter-and-surgical-mitral-valve-repair-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65755.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">389</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">1350</span> An Overview of Corroded Pipe Repair Techniques Using Composite Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lim%20Kar%20Sing">Lim Kar Sing</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Nur%20Afifah%20Azraai"> Siti Nur Afifah Azraai</a>, <a href="https://publications.waset.org/abstracts/search?q=Norhazilan%20Md%20Noor"> Norhazilan Md Noor</a>, <a href="https://publications.waset.org/abstracts/search?q=Nordin%20Yahaya"> Nordin Yahaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polymeric composites are being increasingly used as repair material for repairing critical infrastructures such as building, bridge, pressure vessel, piping and pipeline. Technique in repairing damaged pipes is one of the major concerns of pipeline owners. Considerable researches have been carried out on the repair of corroded pipes using composite materials. This article attempts a short review of the subject matter to provide insight into various techniques used in repairing corroded pipes, focusing on a wide range of composite repair systems. These systems including pre-cured layered, flexible wet lay-up, pre-impregnated, split composite sleeve and flexible tape systems. Both advantages and limitations of these repair systems were highlighted. Critical technical aspects have been discussed through the current standards and practices.

Laparoscopic hernia repair claims to have less pain, less recurrence, and less wound infection compared to open hernia repair leading to early recovery and return to work. Materials and Methods: Laparoscopic hernia repair has been done in 2100 patients from 1995 till now with a follow-up data of 1350 patients. Data was analysed for results and satisfaction. Results: There is a recurrence rate of 0.1%. Early complications include bleeding, trocar injury and nerve pain. Late complications were rare. Conclusion: Laparoscopic inguinal hernia repair has a steep learning curve but after that the results and patient satisfaction are very good. It should be the procedure of choice in all bilateral and recurrent hernias. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laparoscopy" title="laparoscopy">laparoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=hernia" title=" hernia"> hernia</a>, <a href="https://publications.waset.org/abstracts/search?q=mesh" title=" mesh"> mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=surgery" title=" surgery"> surgery</a> </p> <a href="https://publications.waset.org/abstracts/51394/results-of-twenty-years-of-laparoscopic-hernia-repair-surgeries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51394.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">253</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">1348</span> Functional Outcome and Quality of Life of Conservative versus Surgical Management of Adult Potts Disease: A Prospective Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Angelo%20Maranon">Mark Angelo Maranon</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Endriga"> David Endriga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The aim of the study is to determine the differences in functional outcome and quality of life of adult patients with Potts disease who have undergone surgical versus non-surgical management.

In addition, it is recommended to use materials for hard tissue repair in open or closed fractures. It is important to use complex minerals with a beneficial effect on hard tissue repair, stimulating cell growth in the bone. Materials that could help avoid bone fracture inflammatory reaction and speed up bone fracture repair are of utmost importance in the treatment of bone fractures. Similar to minerals, the inner eggshell membrane consists of carbohydrates, lipids, proteins with the high pH, high calcium absorptive capacity and with faster bone fracture repair ability. In the present radiographic survey, eggshell-derived bone graft substitutes were used for bone defect repair in 8 dog tibia, measuring bone density on the day of implant placement and 30 and 60 days after placement. In fact, the result of this study shows the difference in bone growth and misshapen bones between treatment and control sites. Cell growth was adequate in treatment sites and misshapen bones were less frequent here than in control sites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20repair" title="bone repair">bone repair</a>, <a href="https://publications.waset.org/abstracts/search?q=eggshell%20powder" title=" eggshell powder"> eggshell powder</a>, <a href="https://publications.waset.org/abstracts/search?q=implant" title=" implant"> implant</a>, <a href="https://publications.waset.org/abstracts/search?q=radiography" title=" radiography"> radiography</a> </p> <a href="https://publications.waset.org/abstracts/34008/a-radiographic-survey-of-eggshell-powder-effect-on-tibial-bone-defect-repair-tested-in-dog" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34008.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">322</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">1345</span> Development and Evaluation of Surgical Sutures Coated with Antibiotic Loaded Gold Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunitha%20Sampathi">Sunitha Sampathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Pankaj%20Kumar%20Tiriya"> Pankaj Kumar Tiriya</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Gera"> Sonia Gera</a>, <a href="https://publications.waset.org/abstracts/search?q=Sravanthi%20Reddy%20Pailla"> Sravanthi Reddy Pailla</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Likhitha"> V.

Maruthi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Surgical site infections (SSIs) are the most common nosocomial infections localized at the incision site. With an estimated 27 million surgical procedures each year in USA, approximately 2-5% rate of SSIs are predicted to occur annually. SSIs are treated with antibiotic medication. Current trend suggest that the direct drug delivery from the suture to the scared tissue can improve patient comfort and wound recovery. For that reason coating the surface of the medical device such as suture and catguts with broad spectrum antibiotics can prevent the formation of bactierial colonies with out comprimising the mechanical properties of the sutures.Hence, the present study was aimed to develop and evaluate a surgical suture coated with an antibiotic Ciprofloxacin hydrochloride loaded on gold nanoparticles. Gold nanoparticles were synthesized by chemical reduction method and conjugated with ciprofloxacin using Polyvinylpyrolidone as stabilizer and gold as carrier. Ciprofloxacin conjugated gold nanoparticles were coated over an absorbable surgical suture made of Polyglactan using sodium alginate as an immobilising agent by slurry dipping technique. The average particle size and Polydispersity Index of drug conjugated gold NPs were found to be 129±2.35 nm and 0.243±0.36 respectively. Gold nanoparticles are characterized by UV-Vis absorption spectroscopy, Fourier Transform Infrared Spectroscopy (FT-IR), Scanning electron microscopy and Transmission electron microscopy. FT-IR revealed that there is no chemical interaction between drug and polymer. Antimicrobial activity for coated sutures was evaluated by disc diffusion method on culture plates of both gram negative (E-coli) and gram positive bacteria (Staphylococcus aureus) and results found to be satisfactory. In vivo studies for coated sutures was performed on Swiss albino mice and histological evaluation of intestinal wound healing parameters such as wound edges in mucosa, muscularis, presence of necrosis, exudates, granulation tissue, granulocytes, macrophages, restoration, and repair of mucosal epithelium and muscularis propria on day 7 after surgery were studied. The control animal group, sutured with plain suture (uncoated suture) showed signs of restoration and repair, but presence of necrosis, heamorraghic infiltration and granulation tissue was still noticed. Whereas the animal group treated with ciprofloxacin and ciprofloxacin gold nanoparticle coated sutures has shown promising decrease in terms of haemorraghic infiltration, granulation tissue, necrosis and better repaired muscularis layers on comparision with plain coated sutures indicating faster rate of repair and less chance of sepsis. Hence coating of sutures with broad spectrum antibiotics can be an alternate technique to reduce SSIs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ciprofloxacin%20hydrochloride" title="ciprofloxacin hydrochloride">ciprofloxacin hydrochloride</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoparticles" title=" gold nanoparticles"> gold nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20site%20infections" title=" surgical site infections"> surgical site infections</a>, <a href="https://publications.waset.org/abstracts/search?q=sutures" title=" sutures"> sutures</a> </p> <a href="https://publications.waset.org/abstracts/45056/development-and-evaluation-of-surgical-sutures-coated-with-antibiotic-loaded-gold-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45056.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">256</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">1344</span> A Systematic Review of Patient-Reported Outcomes and Return to Work after Surgical vs. Non-surgical Midshaft Humerus Fracture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Alasiri">Jamal Alasiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Naif%20Hakeem"> Naif Hakeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Saoud%20Almaslmani"> Saoud Almaslmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Patients with humeral shaft fractures have two different treatment options. Surgical therapy has lesser risks of non-union, mal-union, and re-intervention than non-surgical therapy. These positive clinical outcomes of the surgical approach make it a preferable treatment option despite the risks of radial nerve palsy and additional surgery-related risk. We aimed to evaluate patients’ outcomes and return to work after surgical vs. non-surgical management of shaft humeral fracture. Methods: We used databases, including PubMed, Medline, and Cochrane Register of Controlled Trials, from 2010 to January 2022 to search for potential randomised controlled trials (RCTs) and cohort studies comparing the patients’ related outcome measures and return to work between surgical and non-surgical management of humerus fracture. Results: After carefully evaluating 1352 articles, we included three RCTs (232 patients) and one cohort study (39 patients). The surgical intervention used plate/nail fixation, while the non-surgical intervention used a splint or brace procedure to manage shaft humeral fracture. The pooled DASH effects of all three RCTs at six (M.D: -7.5 [-13.20, -1.89], P: 0.009) I2:44%) and 12 months (M.D: -1.32 [-3.82, 1.17], p:0.29, I2: 0%) were higher in patients treated surgically than in non-surgical procedures. The pooled constant Murley score at six (M.D: 7.945[2.77,13.10], P: 0.003) I2: 0%) and 12 months (M.D: 1.78 [-1.52, 5.09], P: 0.29, I2: 0%) were higher in patients who received non-surgical than surgical therapy. However, pooled analysis for patients returning to work for both groups remained inconclusive. Conclusion: Altogether, we found no significant evidence supporting the clinical benefits of surgical over non-surgical therapy. Thus, the non-surgical approach remains the preferred therapeutic choice for managing shaft humeral fractures due to its lesser side effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shaft%20humeral%20fracture" title="shaft humeral fracture">shaft humeral fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20treatment" title=" surgical treatment"> surgical treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=Patient-related%20outcomes" title=" Patient-related outcomes"> Patient-related outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=return%20to%20work" title=" return to work"> return to work</a>, <a href="https://publications.waset.org/abstracts/search?q=DASH" title=" DASH"> DASH</a> </p> <a href="https://publications.waset.org/abstracts/149651/a-systematic-review-of-patient-reported-outcomes-and-return-to-work-after-surgical-vs-non-surgical-midshaft-humerus-fracture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149651.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">1343</span> Congenital Diaphragmatic Hernia Outcomes in a Low-Volume Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Vieth">Michael Vieth</a>, <a href="https://publications.waset.org/abstracts/search?q=Aric%20Schadler"> Aric Schadler</a>, <a href="https://publications.waset.org/abstracts/search?q=Hubert%20Ballard"> Hubert Ballard</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20A.%20Bauer"> J.

Previous literature suggests improved CDH outcomes at high-volume regional referral centers compared to low-volume centers. The purpose of this study was to examine CDH outcomes at Kentucky Children’s Hospital (KCH), a low-volume center, compared to the Congenital Diaphragmatic Hernia Study Group (CDHSG). Methods: A retrospective chart review was performed at KCH from 2007-2019 for neonates with CDH, and then subdivided into two cohorts: those requiring ECMO therapy and those not requiring ECMO therapy. Basic demographic data and measures of mortality and morbidity including ventilator days and length of stay were compared to the CDHSG. Measures of morbidity for the ECMO cohort including duration of ECMO, clinical bleeding, intracranial hemorrhage, sepsis, need for continuous renal replacement therapy (CRRT), need for sildenafil at discharge, timing of surgical repair, and total ventilator days were collected. Statistical analysis was performed using IBM SPSS Statistics version 28. One-sample t-tests and one-sample Wilcoxon Signed Rank test were utilized as appropriate.Results: There were a total of 27 neonatal patients with CDH at KCH from 2007-2019; 9 of the 27 required ECMO therapy. The birth weight and gestational age were similar between KCH and the CDHSG (2.99 kg vs 2.92 kg, p =0.655; 37.0 weeks vs 37.4 weeks, p =0.51). About half of the patients were inborn in both cohorts (52% vs 56%, p =0.676). KCH cohort had significantly more Caucasian patients (96% vs 55%, p=<0.001). Unadjusted mortality was similar in both groups (KCH 70% vs CDHSG 72%, p =0.857). Using ECMO utilization (KCH 78% vs CDHSG 52%, p =0.118) and need for surgical repair (KCH 95% vs CDHSG 85%, p =0.060) as proxy for severity, both groups’ mortality were comparable. No significant difference was noted for pulmonary outcomes such as average ventilator days (KCH 43.2 vs. CDHSG 17.3, p =0.078) and home oxygen dependency (KCH 44% vs. CDHSG 24%, p =0.108). Average length of hospital stay for patients treated at KCH was similar to CDHSG (64.4 vs 49.2, p=1.000). Conclusion: Our study demonstrates that outcome in CDH patients is independent of center’s case volume status. Management of CDH with a standardized approach in a low-volume center can yield similar outcomes. This data supports the treatment of patients with CDH at low-volume centers as opposed to transferring to higher-volume centers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ECMO" title="ECMO">ECMO</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20volume" title=" case volume"> case volume</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20diaphragmatic%20hernia" title=" congenital diaphragmatic hernia"> congenital diaphragmatic hernia</a>, <a href="https://publications.waset.org/abstracts/search?q=congenital%20diaphragmatic%20hernia%20study%20group" title=" congenital diaphragmatic hernia study group"> congenital diaphragmatic hernia study group</a>, <a href="https://publications.waset.org/abstracts/search?q=neonate" title=" neonate"> neonate</a> </p> <a href="https://publications.waset.org/abstracts/165258/congenital-diaphragmatic-hernia-outcomes-in-a-low-volume-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165258.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">96</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">1342</span> The Breast Surgery Movement: A 50 Year Development of the Surgical Specialty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Zammerilla%20Westcott">Lauren Zammerilla Westcott</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronald%20C.%20Jones"> Ronald C.

This article examines the happenings that led to the transition of breast surgery as a subset of general surgery to its own specialized field. Sparked by the research of Dr. Bernard Fisher and the first National Surgical Adjuvant Breast and Bowel Project trial in 1971, the field of breast surgery underwent significant growth over the next several decades, enabling general surgeons to limit their practices to the breast. High surgical volumes eventually led to the development of the first formal breast surgical oncology fellowship in a large community-based hospital at Baylor University Medical Center in 1982. The establishment of the American Society of Breast Surgeons, as well several landmark clinical trials and public campaign efforts, further contributed to the advancement of breast surgery, making it the specialized field of the current era. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20fellowship" title=" breast fellowship"> breast fellowship</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20surgery" title=" breast surgery"> breast surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=surgical%20history" title=" surgical history"> surgical history</a> </p> <a href="https://publications.waset.org/abstracts/139585/the-breast-surgery-movement-a-50-year-development-of-the-surgical-specialty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139585.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">1341</span> Analysis of Arthroscopic Rotator Cuff Repair</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prakash%20Karrun">Prakash Karrun</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Manoj%20Deepak"> M.

There is a single server who comes immediately to do inspection and repair whenever needed. On the failure of standard firearm, the server inspects the operative country-made firearm to see whether the unit is capable of performing the desired function well or not. If country-made firearm is not capable to do so, the operation of the system is stopped and server starts repair of the standard firearms immediately. However, no inspection is done at the failure of the country-made firearm as the country-made firearm alone is capable of performing the given task well. In model I, priority to repair the standard firearm is given in case system fails completely and country-made firearm is already under repair, whereas in model II there is no such priority. The failure and repair times of each unit are assumed to be independent and uncorrelated random variables. The distributions of failure time of the units are taken as negative exponential while that of repair and inspection times are general. By using semi-Markov process and regenerative point technique some econo-reliability measures are obtained. Graphs are plotted to compare the MTSF (mean time to system failure), availability and profit of the models for a particular case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=non-identical%20firearms" title="non-identical firearms">non-identical firearms</a>, <a href="https://publications.waset.org/abstracts/search?q=inspection" title=" inspection"> inspection</a>, <a href="https://publications.waset.org/abstracts/search?q=priority%20to%20repair" title=" priority to repair"> priority to repair</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-Markov%20process" title=" semi-Markov process"> semi-Markov process</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20point" title=" regenerative point"> regenerative point</a> </p> <a href="https://publications.waset.org/abstracts/6163/comparative-study-of-non-identical-firearms-with-priority-to-repair-subject-to-inspection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6163.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">425</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">1339</span> A Case of Survival with Self-Draining Haemopericardium Secondary to Stabbing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balakrishna%20Valluru">Balakrishna Valluru</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruth%20Suckling"> Ruth Suckling</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 16 year old male was found collapsed on the road following stab injuries to the chest and abdomen and was transported to the emergency department by ambulance. On arrival in the emergency department the patient was breathless and appeared pale. He was maintaining his airway with spontaneous breathing and had a heart rate of 122 beats per minute with a blood pressure of 83/63 mmHg. He was resuscitated initially with three units of packed red cells. Clinical examination identified three incisional wounds each measuring 2 cm. These were in the left para-sternal region, right infra-scapular region and left upper quadrant of the abdomen. The chest wound over the left parasternal area at the level of 4tth intercostal space was bleeding intermittently on leaning forwards and was relieving his breathlessness intermittently. CT imaging was performed to characterize his injuries and determine his management. CT scan of chest and abdomen showed moderate size haemopericardium with left sided haemopneumothorax. The patient underwent urgent surgical repair of the left ventricle and left anterior descending artery. He recovered without complications and was discharged from the hospital. This case highlights the fact that the potential to develop a life threatening cardiac tamponade was mitigated by the left parasternal stab wound. This injury fortuitously provided a pericardial window through which the bleeding from the injured left ventricle and left anterior descending artery could drain into the left hemithorax providing an opportunity for timely surgical intervention to repair the cardiac injuries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stab" title="stab">stab</a>, <a href="https://publications.waset.org/abstracts/search?q=incisional" title=" incisional"> incisional</a>, <a href="https://publications.waset.org/abstracts/search?q=haemo-pericardium" title=" haemo-pericardium"> haemo-pericardium</a>, <a href="https://publications.waset.org/abstracts/search?q=haemo-pneumothorax" title=" haemo-pneumothorax"> haemo-pneumothorax</a> </p> <a href="https://publications.waset.org/abstracts/69860/a-case-of-survival-with-self-draining-haemopericardium-secondary-to-stabbing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69860.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">201</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">1338</span> Shunt Placement in Treatment of Hydrocephalus in Patients with Myelomeningocele</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Akhmediev">M.

Objective: It’s sought to improve the results of the surgical treatment of hydrocephalus in children with spina bifida. Methods: We have analyzed the results of the surgical treatment of 80 patients aged between 1 month and 1,5-year-old with hydrocephalus and myelomeningocele. All patients underwent surgery in the period of 2013-2018. Results: In all patients, spina bifida was associated with hydrocephalus with a predominant extension of the posterior horns of the lateral ventricles in the form of colpocephaly, Chiari malformation type 2. Based on the method “Choose right shunt” the determination of the point of critical deformation of the ventricular system was established, 47 (58.8%) patients for the 1st stage underwent ventriculoperitoneal (VP) shunt surgery with a low-pressure valve, 28 (35.0%) patients with medium pressure and 5 (6.2%) with high-pressure valve. Under or over drainage complications were not observed in the postoperative period. The 2nd stage of surgery for myelomeningocele repair was planned in 1-2 months with the follow-up head ultrasonography and electromyography study. Conclusion: The implantable shunt systems parameters chosen before surgery in the surgical management of hydrocephalus in children with myelomeningocele are important in the causes of under or over drainage states, cerebrospinal fluid leakage from the myelomeningocele sac. Management of hydrocephalus should be performed by considering myelomeningocele affecting craniospinal compliance. <p class="card-text"><strong>Keywords:</strong> <a
