Electrical stimulation of the posterior tibialis nerve improves symptoms of poststroke neurogenic overactive bladder in men: a randomized controlled trial.

Objective: To evaluate the effectiveness of electrical stimulation of the posterior tibialis nerve in men with neurogenic overactive bladder secondary to ischemic stroke at 45 days and 12 months after treatment.

Materials And Methods: We studied 24 patients older than 18 years, with ischemic stroke that occurred between 6 months and 3 years previously and with no prior urinary symptoms. These patients were randomly allocated to receive electrical stimulation of the posterior tibialis nerve twice weekly for 6 weeks (treatment group, n = 12) or general advice and stretching sessions 1 to 3 times monthly for 6 weeks (control group, n = 12).

Beta-binomial/Poisson regression models for repeated bivariate counts.

We analyze data obtained from a study designed to evaluate training effects on the performance of certain motor activities of Parkinson's disease patients. Maximum likelihood methods were used to fit beta-binomial/Poisson regression models tailored to evaluate the effects of training on the numbers of attempted and successful specified manual movements in 1 min periods, controlling for disease stage and use of the preferred hand. We extend models previously considered by other authors in univariate settings to account for the repeated measures nature of the data.

Strict guideline reduces the need for RBC transfusions in premature infants.

The aim of this study was to verify if the adoption of a strict guideline would reduce the need for red blood cell transfusions in the first 28 days of life in very low birth weight preterm infants. Retrospective study of two cohorts of very low birth weight infants transfused according to neonatologist decision (Period 1) or according to a strict guideline for erythrocytes transfusion (Period 2). Clinical and hematological data of 80 premature infants transfused in both periods of the study were obtained by chart review.

Salivary cortisol as an indicator of adrenocortical function in healthy infants, using massage therapy.

Context And Objective: The evaluation of adrenocortical function with the use of therapeutic massage has been little studied in Brazil. The purpose of this study was to evaluate the salivary cortisol levels before and after Shantala massage therapy on healthy infants.

Design And Setting: Prospective case series, in a public nursery, in São Paulo.

Cognitive dysfunction in children with sleep-disordered breathing.

Two daily school periods are mandatory in Brazil owing to a shortage of academic facilities, which can decrease cognitive performance, especially in children with sleep-disordered breathing. This study aimed to verify the influence of starting time to school on cognition, comparing children with sleep disorders and normal children. Cognition was assessed in 79 children with sleep-disordered breathing, 468 children with nonrespiratory sleep disorders, and 633 normal control children.
