No. of bitstreams: 0 Previous issue date: 2004; PURPOSE: The aim of this study was to identify the tissue defense immunoinflammatory mechanisms present in the healing process of anal region wounds resulting from hemorrhoidectomy by the open technique. METHODS: Immunohistochemical techniques were applied to biopsies of anal wounds obtained on Day 0 and Day ...
Oclusão arteriolar retiniana e a oxigenoterapia hiperbárica
Pereira, C; Pina, S; Azevedo, AR; Silva, I; Franco, M; Filipe, H; Cavalheiro, D; Guerreiro, FIntrodução: A oxigenoterapia hiperbárica (OTHB) consiste na administração de uma fracção inspirada de oxigénio próximo de 100%, num ambiente com uma pressão superior (2,5 atm) a pressão atmosférica a nível do mar. este aumento de pressão irá resultar num aumento da pressão arterial e tecidular de oxigénio, em que o volume de oxigénio dissolvido e transportado pelo plasma, aumenta mais de 22 vezes, o que estará ...
Bull's Eye Maculopathy in a Patient Treated with Efavirenz
Vaz Pereira, C; Franco, M; Guerra Pinto, R; Lino, S; Maltez, F; Barrão, S; Filipe, HObjective: To report a case of retinal toxicity associated with efavirenz in an adult. Methods: We describe a case of gradual-onset blurry vision in both eyes in a 37-year-old HIV Caucasian woman, on antiretroviral therapy (ART), including efavirenz. Results: The patient presented with a best corrected visual acuity of 20/100 for the right eye (RE) and 20/125 for the left eye (LE). Fundoscopy revealed mottled a...

Torção aguda do cordão espermático: factor de risco para anticorpos anti-esperm...
Graça, B; Coelho, M; Franco, MA torção aguda do cordão espermático é uma urgência urológica dada a isquémia testicular acompanhante, podendo mesmo levar à necrose testicular se não resolvida atempadamente. A correcção cirúrgica passa pela destorção do cordão espermático atingido e orquidopexia bilateral ou, na presença de torção com isquémia testicular irreversível, pela orquidectomia e orquidopexia contralateral. As eventuais sequelas dest...
Spreading of HIV-1 subtype G and envB/gagG recombinant strains among injecting ...
Esteves, A; Parreira, R; Piedade, J; Venenno, T; Franco, M; Sousa, JG; Patrício, L; Brum, P; Costa, A; Canas-Ferreira, WWe have evaluated the genetic diversity of HIV-1 strains infecting injecting drug users (IDUs) in Lisbon, Portugal. Heteroduplex mobility assay and/or phylogenetic analysis revealed that env (C2V3C3 or gp41) subtype B is present in 63.7% of the 135 viral samples studied, followed by subtypes G (23.7%), A (6.7%), F (5.2%), and D (0.7%). Similar analysis of gag (p24/p7) performed on 91 of the specimens demonstrat...
Molecular epidemiology of HIV type 1 infection in Portugal: high prevalence of ...
Esteves, A; Parreira, R; Venenno, T; Franco, M; Piedade, J; Sousa, JG; Canas-Ferreira, WIn this study, we have investigated the diversity of current HIV-1 strains circulating in the metropolitan area of Lisbon, Portugal. A total of 217 HIV-1-positive blood samples, collected between October 1998 and December 2000, was genetically characterized in the gp120 C2V3C3 region (n = 205) or part of the gp41 N-terminal segment (n = 12) by heteroduplex mobility assay (HMA) and/or DNA sequencing. The HMA sub...
