Sixty patients complaining of frequency, urgency, nocturia, urge incontinence and stress incontinence were randomly allocated to either undergo conservative treatment by way of combined physiotherapy and bladder retraining as an inpatient without prior urodynamics, or to have urodynamic investigations and treatment tailored to the urodynamic diagnosis. The assessment period was 3 months and assessment was made pre-and posttreatment by urinary diary, pad testing and subjective questionnaire. There was a significant improvement posttreatment for each parameter studied, with the exception of pad testing. There was no significant difference between the two groups for any parameter. Two-thirds of patients were cured to the extent that they did not require further treatment, and again there was no difference between the two groups. We conclude that patients attending for the first time with an uncomplicated story of urinary incontinence can be effectively treated conservatively without prior urodynamics.
OBJECTIVE With nearly half of graduating US medical students being female, it is imperative to understand why females typically make up less than 20% of the neurosurgery applicant pool, a number that has changed very slowly over the past several decades. Organized neurosurgery has strongly indicated the desire to overcome the underrepresentation of women, and it is critical to explore whether females are at a disadvantage during the residency application process, one of the first steps in a neurosurgical career. To date, there are no published studies on specific applicant characteristics, including gender, that are associated with match outcome among neurosurgery resident applicants. The purpose of this study is to determine which characteristics of neurosurgery residency applicants, including gender, are associated with a successful match outcome. METHODS De-identified neurosurgical resident applicant data obtained from the San Francisco Fellowship and Residency Matching Service for the years 1990-2007 were analyzed. Applicant characteristics including gender, medical school attended, year of application, United States Medical Licensing Exam (USMLE) Step 1 score, Alpha Omega Alpha (AOA) status, and match outcome were available for study. RESULTS Of the total 3426 applicants studied, 473 (13.8%) applicants were female and 2953 (86.2%) were male. Two thousand four hundred forty-eight (71.5%) applicants successfully matched. USMLE Step 1 score was the strongest predictor of match outcome with scores > 245 having an OR of 20.84 (95% CI 10.31-42.12) compared with those scoring < 215. The mean USMLE Step 1 score for applicants who successfully matched was 233.2 and was 210.8 for those applicants who did not match (p < 0.001). Medical school rank was also associated with match outcome (p < 0.001). AOA status was not significantly associated with match outcome. Female gender was associated with significantly lower odds of matching in both simple (OR 0.59, 95% CI 0.48-0.72) and multivariate analyses (OR 0.57, 95% CI 0.34-0.94 CI). USMLE Step 1 scores were significantly lower for females compared to males with a mean score of 230.1 for males and 221.5 for females (p < 0.001). There was no significant difference in medical school ranking or AOA status when stratified by applicant gender. CONCLUSIONS The limited historical applicant data from 1990-2007 suggests that USMLE Step 1 score is the best predictor of match outcome, although applicant gender may also play a role.
Schwannomatosis is a multiple tumor syndrome in which patients develop benign tumors along peripheral nerves throughout the body. The first symptom with which schwannomatosis patients often present, prior to discovery of tumors, is pain. This pain can be debilitating and is often inadequately alleviated by pharmacological approaches. Schwannomatosis-associated pain can be localized to the area of a tumor, or widespread. Moreover, not all tumors are painful, and the occurrence of pain is often unrelated to tumor size or location. We speculate that some individual tumors, but not others, secrete factors that act on nearby nerves to augment nociception by producing neuronal sensitization or spontaneous neuronal firing. We created cell lines from human SWN tumors with varying degrees of pain. We have found that conditioned medium (CM) collected from painful SWN tumors, but not that from nonpainful SWN tumors, sensitized DRG neurons, causing increased sensitivity to depolarization by KCl, increased response to noxious TRPV1 and TRPA1 agonists and also upregulated the expression of pain-associated genes in DRG cultures. Multiple cytokines were also detected at higher levels in CM from painful tumors. Taken together our data demonstrate a differential ability of painful versus non-painful human schwannomatosis tumor cells to secrete factors that augment sensory neuron responsiveness, and thus identify a potential determinant of pain heterogeneity in schwannomatosis.
Seventy-four patients presenting with a mixed pattern of urinary symptoms were randomly allocated to undergo either inpatient or outpatient continence programs as initial treatment, without prior urodynamic investigation. Both programs consisted of physiotherapy, bladder retraining, fluid normalization, dietary advice and general support and advice. Nine out of 39 in the outpatient group and 8 out of the 35 of the inpatient group failed to complete the study. There was a significant decrease in frequency, nocturia, number of incontinent episodes and visual analog scores for both groups. In addition the outpatients had a significant reduction in loss on pad testing, and a significantly greater improvement in their visual analog score. In each group 63% were cured or improved to the extent that they did not require further treatment. Staff costs per outpatient were half those for an inpatient. We conclude that outpatient conservative treatment as detailed above is a successful first-line treatment of urinary incontinence in women. It is as successful and possibly better than inpatient treatment, and is significantly cheaper.
