Background:Postoperative infection is one of the most common complications after spine surgeries. In our study, surgical site infection (SSI) is described as; superficial (i.e., skin and subcutaneous tissues) and deep (i.e., fascia and muscles) infections occurring in the short term (i.e., 1-month) after spine surgeries (Centers for Disease Control and Prevention definition 81.00–81.08). To detect the risk factors for the occurrence of such a complication, studies require a large number of patients, a high quality of data and adequate analysis. In this study, we prospectively enrolled 987 patients undergoing spinal surgery over a 3 years period.Methods:From November 2010 to November 2013, 987 patients had a variety of spinal operations that included; disc herniation, spinal stenosis, spondylolisthesis, fracture-dislocations, spine and spinal cord tumors, and syringomyelia. Patients under the age of 10, those with a recent history of infection and antibiotherapy, and patients with immunodeficiency disorders were excluded.Results:Of the 987 spine procedures performed, 27 (2.73%) developed postoperative infections. Multi-variant data analysis indicated that multiple factors correlated with an increased risk of SSI in descending order; trauma, a past history of diabetes, smoking, being confined to bed, in the perioperative period, mean blood sugar levels above 120 mg/dl, longer lengths of incisions, and longer hospital stay.Conclusion:Considering the preventable nature of most of the factors contributing to SSI, it should be possible to reduce these complications.

Introduction Premature ejaculation (PE) is regarded as the most common male sexual disorder. To date, there is no accurate and objective diagnostic test for PE. Aim To determine the diagnostic value of serum leptin level for PE. Methods In a case-control design, the serum leptin level of 46 PE patients referred to our outpatient clinic were determined and compared with 44 control patients referred to the same clinic with the complaint of nephrolithiasis. PE was defined based on the Diagnostic and Statistical Manual of Mental Disorders IV criteria and an intravaginal ejaculatory latency time of less than a minute. Main Outcome Measures Serum leptin level and presence of PE. Results The PE patients had significantly higher serum leptin levels (8.3 ± 3 ng/mL) than the controls (3.3 ± 1 ng/mL) (P < 0.001). Sensitivity and specificity for the test as a predictive diagnostic tool for PE were 80.4% and 97.7%, respectively, at the cutoff value of 6.3 ng/mL. Conclusion According to our results, leptin level in patients with PE was significantly higher than in the control subjects. More studies are necessary to determine the value of serum leptin as a diagnostic tool for PE.

BACKGROUND:The mechanisms and outcomes in coronavirus disease (COVID-19)associated stroke are unique from those of non-COVID-19 stroke. OBJECTIVE: To describe the efficacy and outcomes of acute revascularization of large vessel occlusion (LVO) in the setting of COVID-19 in an international cohort. METHODS: We conducted an international multicenter retrospective study of consecutively admitted patients with COVID-19 with concomitant acute LVO across 50 comprehensive stroke centers. Our control group constituted historical controls of patients presenting with LVO and receiving a mechanical thrombectomy between January 2018 and December 2020. RESULTS: The total cohort was 575 patients with acute LVO; 194 patients had COVID-19 while 381 patients did not. Patients in the COVID-19 group were younger (62.5 vs 71.2; P < .001) and lacked vascular risk factors (49, 25.3% vs 54, 14.2%; P = .001). Modified thrombolysis in cerebral infarction 3 revascularization was less common in the COVID-19 group (74, 39.2% vs 252, 67.2%; P < .001). Poor functional outcome at discharge (defined as modified Ranklin Scale 3-6) was more common in the COVID-19 group (150, 79.8% vs 132, 66.7%; P = .004). COVID-19 was independently associated with a lower likelihood of achieving modified thrombolysis in cerebral infarction 3 (odds ratio [OR]: 0.4, 95% CI: 0.2-0.7; P < .001) and unfavorable outcomes (OR: 2.5, 95% CI: 1.4-4.5; P = .002). CONCLUSION: COVID-19 was an independent predictor of incomplete revascularization and poor outcomes in patients with stroke due to LVO. Patients with COVID-19 with LVO were younger, had fewer cerebrovascular risk factors, and suffered from higher morbidity/ mortality rates.
