Effects of tadalafil to prevent injury on corpus cavernosum after vascular or nervous peri-prostatic bundle injury. Experimental model in rats.

Purpose: To evaluate the effects of tadalafil (TD) in preventing histological alterations of the corpus cavernosum caused by isolated lesions of cavernous nerve (ILCN) and artery (ILCA) in rats.

Methods: Fifty male Wistar rats were randomly assigned in five groups: G1: control; G2: bilateral ILCN; G3: bilateral ILCA; G4: ILCN+TD; G5: ILCA+TD. The cavernous bodies were submitted to histomorphometry, immunohistochemistry and biochemical analysis.

Assessment of the quality of life of patients with cutaneous leishmaniasis in Belo Horizonte, Brazil, 2009-2010. A pilot study.

Background: Cutaneous leishmaniasis (CL) may manifest as single or multiple skin lesions, causing significant aesthetic impact and affecting the patient's quality of life (QoL). The objective of this study was to assess the impact of CL on the QoL.

Methods: The QoL of 20 patients with CL was assessed by the Dermatology Life Quality Index (DLQI).

Dornase alfa improves the health-related quality of life among Brazilian patients with cystic fibrosis--a one-year prospective study.

Summary Background: Health-related quality of life (HRQOL) measurements provide valuable information about the psychological and social impact of treatment on patients with cystic fibrosis (CF). This study evaluated the HRQOL of Brazilian patients with CF and assessed the changes in HRQOL domains over 1 year after dornase alfa (Pulmozyme) introduction.

Patients And Methods: One hundred fifty-six stable patients with CF and 89 caregivers answered the Portuguese-validated version of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at baseline (T(0)), and at 3 (T(1)), 6 (T(2)), 9 (T(3)), and 12 (T(4)) months of follow-up.

A better understanding of urogenital tuberculosis pathophysiology based on radiological findings.

Purpose: To assess the radiological findings of urogenital tuberculosis (UGT) in patients at different disease stages, for a better understanding of its pathophysiology.

Patients And Methods: We retrospectively reviewed the radiological exams of 20 men (median age 41 years; range: 28-65) with urogenital tuberculosis diagnosis. The patients were classified in the following groups: (1) bilateral renal tuberculosis with predominantly parenchymatous involvement; (2) unilateral renal tuberculosis; (3) unilateral renal tuberculosis with bladder tuberculosis and (4) bilateral renal tuberculosis with bladder tuberculosis.

Seroprevalence of hepatitis B and C in Brazilian army conscripts in 2002: a cross-sectional study.

Hepatitis B and C constitute important public health problems worldwide. In Brazil, studies on prevalence of viral hepatitis have local and regional characteristics; consequently it is difficult to define the national epidemiological situation. Our objective was to evaluate the seroprevalence of hepatitis B and C in conscripts of the Brazilian Army.

Dried blood spots as a practical and inexpensive source for human immunodeficiency virus and hepatitis C virus surveillance.

Passive surveillance of infectious diseases with a high percentage of asymptomatic cases or long incubation periods, such as acquired immunodeficiency syndrome (AIDS), does not reflect the current transmission dynamics. Thus, a multi-strategic surveillance, such as the human immunodeficiency virus (HIV) sentinel surveillance proposed by the World Health Organization (WHO), is necessary. The Brazilian HIV sentinel surveillance was started in May 1992 with this purpose.
