Nuclear medicine imaging technique in the erectile dysfunction evaluation: a mini-review
Provedor de dados: 52
Autores: Ribeiro,Camila Godinho; Moura,Regina; Neves,Rosane de Figueiredo; Spinosa,Jean Pierre; Bernardo-Filho,Mario.
Functional imaging with positron emission tomography and single photon emission computed tomography is capable of visualizing subtle changes in physiological function in vivo. Erectile dysfunction(ED) diminishes quality of life for affected men and their partners. Identification of neural substrates may provide information regarding the pathophysiology of types of sexual dysfunction originating in the brain. The aim of this work is to verify the approaches of the nuclear medicine techniques in the evaluation of the erectile function/disfunction. A search using the words ED and nuclear medicine, ED and scintigraphy, ED and spect and ED and pet was done in the PubMed. The number of citations in each subject was determined. Neuroimaging techniques offer...

Prevalence and risk factors for erectile dysfunction in HIV-infected patients in Salvador, Brazil
Provedor de dados: 55
Autores: Gomes,Tacila Veras; Brites,Carlos.
ABSTRACT  Background: Effective antiretroviral therapy (ART) has increased life expectancy for HIV patients to levels close to that observed for general population. Comorbidities are also increasing, due to ageing of such population. Erectile dysfunction (ED) has been a frequent finding in men living with HIV.  Objectives: The goals of the present study were to define the prevalence of ED and associated factors in HIV-infected men, in a referral center of Salvador city, Brazil.  Methods: HIV-infected men ≥18 years of age, receiving care at the AIDS Clinics of Complexo Hospitalar Professor Edgard Santos (C-HUPES), Universidade Federal da Bahia were consecutively included in the study until the estimated sample size (N = 134) was reached. Patients filled a...

Autores: Shinlapawittayatorn,K.; Chattipakorn,S.; Chattipakorn,N.
Sildenafil citrate is a drug commonly used to manage erectile dysfunction. It is designated chemically as 1-[[3-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1H -pyrazolo[4,3-d]pyrimidin-5-yl)-4 ethoxyphenyl] sulfonyl]-4-methylpiperazine citrate (C22H30N6O4 S). It is a highly selective inhibitor of cyclic guanine monophosphate-specific phosphodiesterase type 5. In late March through mid-November 1998, the US Food and Drug Administration (FDA) published a report on 130 confirmed deaths among men (mean age, 64 years) who received prescriptions for sildenafil citrate, a period during which &gt;6 million outpatient prescriptions (representing about 50 million tablets) were dispensed. The US FDA recently reported that significant cardiovascular events, including sudden...

A review of analytical methods for the determination of four new phosphodiesterase type 5 inhibitors in biological samples and pharmaceutical preparations
Provedor de dados: 60
Autores: Codevilla,Cristiane Franco; Castilhos,Tamara dos Santos; Bergold,Ana Maria.
The introduction of oral phosphodiesterase type 5 inhibitor therapy in 1998 revolutionized the treatment of erectile dysfunction. Erectile dysfunction is the most common sexual problem in men. It often has a profound effect on intimate relationships and quality of life. The analysis of pharmaceuticals is an important part of the drug development process as well as for routine analysis and quality control of commercial formulations. Whereas the determination of sildenafil citrate, vardenafil and tadalafil are well documented by a variety of methods, there are few publications about the determination of udenafil, lodenafil carbonate, mirodenafil and avanafil. The paper presents a brief review of the action mechanism, adverse effects, pharmacokinetics and the...
