PURPOSE: Controversy exists over the preoperative risk factors for postoperative urinary retention after the midurethral sling procedure for stress urinary incontinence (SUI). We intended to analyze the effect of preoperative flow rate on postoperative urinary retention after the transobturator tape (TOT) operation. MATERIALS AND METHODS: A total of 322 patients who underwent TOT from June 2006 to May 2012 were included in this retrospective study. All patients were preoperatively investigated for urinary symptoms and underwent preoperative urodynamic studies including urine flow rate. Postoperative urinary retention, voiding difficulty, and uroflowmetry were checked. Urinary retention was defined as the need for additional catheterization longer than 1 day. Patients were divided by preoperative peak flow rate (Qmax) of 15 mL/s (low Qmax group and normal Qmax group). RESULTS: There were 3 cases of postoperative urinary retention (0.9%) and 52 cases of voiding difficulty (16.1%). The low Qmax group included 40 patients (12.4%) and the normal Qmax group included 282 patients (87.5%). Between the two groups, there were no significant differences in age, previous pelvic surgery history, or past medical history. The low Qmax group had higher scores for voided volume and detrusor pressure at Qmax. However, there was no significant difference in postoperative voiding difficulty between the two groups. Furthermore, three patients who experienced postoperative retention showed high flow rates preoperatively. CONCLUSIONS: Our results suggest that voiding difficulty in the group with low preoperative flow was tolerable and the treatment success rate was comparable to that in patients in the normal flow group. According to our analysis, patients with a low flow rate preoperatively can be safely treated with TOT for SUI.

Development of a competence-based curriculum is important. This study aimed to develop competence assessment tools in emergency medicine and use it to assess competence of Cameroonian healthcare professionals. This was a cross-sectional, descriptive study. Through literature review, expert survey, and discrimination tests, we developed a self-survey questionnaire and a scenario-based competence assessment tool for assessing clinical knowledge and self-confidence to perform clinical practices or procedures. The self-survey consisted of 23 domains and 94 questionnaires on a 5-point Likert scale. Objective scenario-based competence assessment tool was used to validate the self-survey results for five life-threatening diseases presenting frequently in emergency rooms of Cameroon. Response rate of the self-survey was 82.6%. In this first half of competence assessment, knowledge of infectious disease had the highest score (4.6 ± 0.4) followed by obstetrics and gynecology (4.2 ± 0.6) and hematology and oncology (4.2 ± 0.5); in contrast, respondents rated the lowest score in the domains of disaster, abuse and assault, and psychiatric and behavior disorder (all of mean 2.8). In the scenario-based test, knowledge of multiple trauma had the highest score (4.3 ± 1.2) followed by anaphylaxis (3.4 ± 1.4), diabetic ketoacidosis (3.3 ± 1.0), ST-elevation myocardial infarction (2.5 ± 1.4), and septic shock (2.2 ± 1.1). Mean difference between the self-survey and scenario-based test was statistically insignificant (mean, −0.02; 95% confidence interval, −0.41 to 0.36), and agreement rate was 58.3%. Both evaluation tools showed a moderate correlation, and the study population had relatively low competence for specific aspects of emergency medicine and clinical procedures and skills.

Ovarian cancer is a leading cause of death in women. Early detection of ovarian cancer is essential to decrease mortality. However, the early diagnosis of ovarian cancer is difficult due to a lack of clinical symptoms and suitable molecular diagnostic markers. Thus, identification of meaningful tumor biomarkers with potential clinical application is clearly needed. To search for a biomarker for the early detection of ovarian cancer, we identified human anterior gradient 2 (AGR2) from our systematic analysis of paired normal and ovarian tumor tissue cDNA microarray. We noted a marked overexpression of AGR2 mRNA and protein in early stage mucinous ovarian tumors compared to normal ovarian tissues and serous type ovarian tumors by Western blot analysis and immunohistochemistry. To further elucidate the role of AGR2 in ovarian tumorigenesis, stable 2774 human ovarian cancer cell lines overexpressing AGR2 were established. Forced expression of AGR2 in 2774 cells enhanced the growth and migration of ovarian cancer cells. AGR2 protein was detected in the serum of mucinous ovarian cancer patients by Western blot and ELISA analysis. Thus, AGR2 is a potential biomarker for the diagnosis of mucinous ovarian cancer and an ELISA assay may facilitate the early detection of mucinous ovarian cancer using patient serum.
