Methods: A retrospective cohort study of all patients who were operated at Hamad General Hospital (HGH) between June 2010 and June 2012 for AT rupture (n = 102), was conducted. Data was collected on 1) patient’ characteristics such as age, sex;2) disease characteristics such as mechanism of rupture, type of rupture (partial or complete), whether an anterior or posterior slab was applied, number of suture materials, number of antibiotics, surgical time, time to surgery and length of hospital stay (LOS), number of follow up visits, and 3) complications. Descriptive and analytical statistical analyses were applied. Receiver operating characteristic curve was applied to identify the validity of different LOS values, with a significance level at p ≤ 0.05. Results: Of the 102 patients with Achilles rupture, almost males (96.1%), with a mean age 31.07 ± 9.71 years, 52% with complete rupture, the majority were open ruptures (81.4%) and bathroom-related (70.6%). Anterior slab was applied to 58.2% and 2 types of suture materials to 71.6% of cases. Fifteen cases (14.7%, 95% CI: 7.8% - 21.6%) presented with one or more complications (9.8% post-operative infections, 5.9% stiffness and 2% re-rupture). Post-operative infections were significantly associated with: old age (z = 2.11, p = 0.035), longer LOS (z = 2.01, p = 0.04), and presence of diabetes (Fisher exact test: p = 0.003). After adjustment for age, LOS (p = 0.04) and diabetes (p = 0.017) remained as significant predictors of post-operative infections. LOS of 2.5 days was the optimum cut-off point above which post-operative infection is more likely to occur, with sensitivity of 80% and specificity of 54%. Conclusion: Achilles repair post operative infection ranks first as a complication of AT surgical repair, and its incidence is relatively higher in HGH than the counterpart figures in the literature.

However, its role in the prediction of ovarian torsion has been controversial. The aim of the study was to assess the validity of ultrasound in the prediction of ovarian torsion in patients with acute pelvic pain related to clinically suspected ovarian torsion. Methods: A retrospective observational study was conducted at the Ob/Gyn department using a 10-year chart review of all female patients older than 11 years of age with highly suspected ovarian torsion who underwent clinical assessment and ultrasound prior to surgery (n = 62). The sensitivity and specificity of ultrasound were determined by cross-tabulation of the ultrasound and surgical findings. Results: Of the suspected cases, 54 (87.1%) were confirmed to be cases of ovarian torsion by surgery. The majority of the cases were suggestive of ovarian torsion, which was indicated by clinical examination (77.4%), ultrasound (77.4%), or pathological examination (79%). Almost one-half of the cases (46.8%) showed a pain score >6;two-thirds (62.9%) presented with vomiting and/or nausea;and more than one-third (38.7%) presented with leukocytosis. The estimated sensitivity and specificity of ultrasound were 0.74 and 0.0, respectively. The positive predictive value was 0.83. Ultrasound was significantly associated with both clinical examination (p = 0.039) and pain score (p = 0.008). Conclusion: The diagnosis of ovarian torsion cannot be exclusively based on ultrasound. Both clinical and sonographical evaluation of acute pelvic pain should be considered for the diagnosis. A definitive diagnosis remains challenging.展开更多
