The prostate after castration and hormone replacement in a rat model: structural and ultrastructural analysis.

Purpose: To evaluate if late hormonal replacement is able to recover the prostatic tissue modified by androgenic deprivation.

Materials And Methods: 24 rats were assigned into a Sham group; an androgen deficient group, submitted to bilateral orchiectomy (Orch); and a group submitted to bilateral orchiectomy followed by testosterone replacement therapy (Orch+T). After 60 days from surgery blood was collected for determination of testosterone levels and the ventral prostate was collected for quantitative and qualitative microscopic analysis.

Oral Microbial Colonization in Pediatric Intensive Care Unit Patients.

Purpose: The purpose of this study was to assess oral microbial colonization before and after the implementation of an oral hygiene protocol in children admitted to a pediatric intensive care unit (PICU) using nonhospitalized healthy children as a control group.

Methods: Two groups were analyzed in this clinical study: Group G1 (dentate children admitted to the PICU); and Group G2 (nonhospitalized, healthy, dentate children). The G1 group underwent oral assessments before (G1i) and after (G1f) a three-day oral hygiene protocol using 0.

Oral care practices for patients in Intensive Care Units: A pilot survey.

Objective: To assess the level of knowledge and difficulties concerning hospitalized patients regarding preventive oral health measures among professionals working in Intensive Care Units (ICUs).

Study Population And Methods: A cross-sectional survey was conducted among 71 health professionals working in the ICU. A self-administered questionnaire was used to determine the methods used, frequency, and attitude toward oral care provided to patients in Brazilian ICUs.

Practical Computerized Solution for Incision and Grafting in Peyronie's Disease.

Introduction: Penile curvature correction with plaque incision and graft (PIG) increases the risk of erectile dysfunction (ED) and is associated with mechanical and geometric abnormalities.

Aims: The aim of this study was to create and validate a new PIG technique using minimum graft area to correct simple or complex penile curvature with or without hourglass deformity, while avoiding mechanical and geometric abnormalities.

Methods: Using our cotton fabric model, we created a mathematic solution for PIG with no residual defects.

Oral health promotion in patients with chronic renal failure admitted in the Intensive Care Unit.

Oral hygiene deficiency is common in patients treated in ICUs and it enables biofilm colonization by microorganisms that lead to respiratory infections. A 30-year-old female patient with chronic renal failure was hospitalized. Dental procedures were performed in the ICU and contributed to the patient's health after a few days.

A geometric model of plaque incision and graft for Peyronie's disease with geometric analyses of different techniques.

Introduction: A surgical approach with plaque incision and graft (PIG) to correct Peyronie's disease is the best method for complex, large deviations. However, the geometric and mechanical consequences of this intervention are poorly understood.

Aim: The aim of this study was to analyze the geometric and mechanical consequences of PIG on penile straighten surgery.

Effects of castration and late hormonal replacement in the structure of rat corpora cavernosa.

The objective of the study was to evaluate, through quantitative methods, the structural alterations in the corpora cavernosa of rats submitted to orchiectomy as well as the role of late hormone replacement in overturning the possible structural alterations. Twenty-five male rats were assigned into 5 groups with 5 animals each and treated as follows: ORCHIEC-1 = submitted to orchiectomy and sacrificed after 1 month; C-1 = control group sacrificed after 1 month; ORCHIEC-2 = submitted to orchiectomy and sacrificed after 2 months; C-2 = control group sacrificed after 2 months; and T = submitted to orchiectomy, underwent testosterone replacement with testosterone undecanoate (100 mg/kg) after 1 month, and sacrificed after 1 month of hormonal replacement. Smooth muscle, collagen, and elastic system fibers of penile corpora cavernosa were quantified.

Effects of castration and hormone replacement in the urinary bladder of rats: structural, ultrastructural, and biochemical analysis.

We evaluated, by qualitative and quantitative methods, the structural alterations in the bladder wall of rats submitted to surgical castration, as well as the role of hormone replacement in reversing the possible structural alterations. Twenty-four 12-week-old male Sprague-Dawley rats were used. The animals were divided into 3 groups comprising 8 animals each and treated as follows.
