RESUMO
Purpose. To determine the efficacy of 23-gauge pars plana vitrectomy (PPV) for symptomatic posterior vitreous detachment (PVD) on visual acuity (VA) and quality after multifocal intraocular lenses (IOLs). Methods. In this prospective case series, patients who developed symptomatic PVD and were not satisfied with visual quality due to floaters and halos after multifocal IOL implantation underwent PPV. Examinations included LogMAR uncorrected visual acuity (UCVA), intraocular pressure, biomicroscopy, and indirect ophthalmoscopy at baseline and 1, 7, 30, and 180 days postoperatively. Ultrasonography and aberrometry were performed. The Visual Functioning Questionnaire 25 (VFQ-25) was administered preoperatively and at 30 days postoperatively. Both the postoperative UCVA and questionnaire results were compared to preoperative findings using the Wilcoxon test. Results. Sixteen eyes of 8 patients were included. VA significantly improved from 0.17 to 0.09 postoperatively (P = 0.017). All patients reported improvement of halos, glare, and floaters. VFQ-25 scores significantly improved in general vision (P = 0.023), near activities (P = 0.043), distance activities (P = 0.041), mental health (P = 0.011), role difficulties (P = 0.042), and driving (P = 0.016). Conclusion. PPV may increase UCVA and quality of vision in patients with bilateral multifocal IOLs and symptomatic PVD. Larger studies are advised.
RESUMO
We report a 24-year-old man with Vogt-Koyanagi-Harada (VKH) syndrome who developed a macular hole (MH) during the acute inflammatory stage. Spontaneous resolution was unlikely because of the MH dimensions and absence of vitreous adherence. The patient underwent pars plana vitrectomy (PPV) and internal limiting membrane peeling during the acute stage followed by retinopexy with octafluoropropane injection and prone positioning for 5 days. The MH closed and the best-corrected visual acuity (BCVA) improved from 20/400 to 20/40. Prompt surgical intervention may be an alternative for treating MHs and obtaining visual recovery in special cases even in the acute inflammatory stage.
RESUMO
Introdução:A infecção pelo HIV pode levar à imunossupressão progressiva e resultar em um complexo de infecções relacionadas à AIDS e outras manifestações nos indivíduos acometidos. Dados do Boletim Epidemiológico AIDS 2012, relatam, de 1980 a 2010, 241.662 óbitos por AIDS no Brasil. Niterói, no estado do Rio de Janeiro, é um município de médio porte, com cerca de 500 mil habitantes e excelentes indicadores socioeconômicos e culturais.Objetivo:Avaliar a possível relação de sazonalidade existente entre a distribuição temporal da demanda e da positividade de testes sorológicos anti-HIV no Laboratório Central de Saúde Pública Miguelote Viana (LCSPMV), de Niterói, Rio de Janeiro.Métodos:Trata-se de um estudo transversal analítico de série temporal. Foram analisados os dados dedemanda, de positividade dos exames anti-HIV e dos dias trabalhados, coletados de um banco de dados referentes ao período de 2005 a 2010. Os dados foramavaliados estatisticamente por uma série temporal e testes de hipótese para tendência e sazonalidade. O LCSPMV é referência na dosagem de carga viral e níveis deCD4 para todas as unidades de saúde da rede pública de Niterói e também atende à população oriunda dos municípios que fazem parte da Região MetropolitanaII.Esta é uma pesquisa inovadora, visto que ainda não foram encontrados artigos que correlacionem aumentos/diminuições das demandas de exames anti-HIV com osrespectivos meses dos anos.Resultados:No período de janeiro de 2005 até dezembro de 2010, registramos 64.505 exames sorológicos anti-HIV, sendo em 2005,17,44% (11.252); em 2006, 16,36% (10.557); em 2007, 17,81% (11.494); em 2008, 17,12% (11.046); em 2009, 16,20% (10.452); e em 2010,15,04%(9.704).
Introduction:HIV infection can lead to a progressive immunosuppression and result in an AIDS-related infections complex and other manifestations in affected individuals. Data from the AIDS 2012 Epidemiological Bulletin from 1980 to 2010 reported 241,662 deaths from AIDS in Brazil. Niterói, in Rio de Janeiro State, isa medium-sized city, of 500,000 in habitants approximately and expressive socioeconomic and cultural indicators.Objective:To evaluate the relations hip between seasonal demand and positivity of anti-HIV tests in the Miguelote Viana Public Health Central Laboratory located in Niterói.Methods:This is a temporal series analytical cross-sectional study. Anti-HIV tests demand, positivity and days worked by Miguelote Viana Public Health Central Laboratory were analyzed froma database for the period from 2005 to 2010. Data was then statistically evaluated through a temporal seriesand hypothesis testing on tendency and seasonality.Miguelote Viana Public Health Central Laboratory is a reference center for the dosage of viral load and CD4 levels for all public health units of Niterói; also attending to the population of cities in Metropolitan Region II. This is an innovative research, since articles that relate anti-HIV tests demand increase/decrease with the respective months of the year have not been found yet. As a result, we present graphs, tables and charts.Results:From January 2005 to December 2010,we have registered 64,505 serological tests for HIV, as follows: 17.44% (11,252) in 2005; 16.36% (10,557) in 2006; 17.81% (11,494) in 2007; 17.12% (11,046)in 2008; 16.20% (10,452) in 2009; and 15.04% (9,704) in 2010. In annual average, the days worked per month were as follows: 20in 2005; 19.5 in 2006; 19.8 in2007; 19.6 in 2008; 19.7 in 2009 and 19.3 in 2010. The monthly average of days worked in the six years studied was: 21 in Jan; 17.3 in February; 21.6 in March;17.3 in April; 20 in May; 18.6 in June; 21.6 in July; 22 in August; 20.3 in September; 20.3 in October; 17.3 in November and 18.6 days in December. The annual average of positivity in absolute numbers was as follows: 42.6 in 2005; 44.0 in 2006; 38.3 in 2007; 32.8 in 2008; 24.25 in 2009and 25.25 in 2010. The average positivity per month in the six years studied was the following: 39.3 in January; 29.3 in February; 40.8 in March; 31.8 in April; 31.1 in May; 34.6 in June; 33.8 inJuly; 38.6 in August; 35.0 in September; 34.8 in October; 31.5 in November and 33.6 in December. The average percentage of positivity per month was as follows:January (4.35), February (3.85), March (3.95), April (3.88), May (3.56), June (2.34), July (3.54), August (3.80), September (3.79), October (3.60), November (3.92)and December (3.75). In the studied period (2005-2010), Carnival holidays occurred in the month of February, on the following days: 8, 28, 20, 5, 24 and 16,respectively.Conclusion:We observed no seasonal relation between demand and positivity of anti-HIV tests carried out at Miguelote Viana Public Health Central Laboratory. A significant statistical decrease occurred in both anti-HIV tests demand and positivity during the studied years of the 2005-2010 series.
