Lacrimal excretory system sequelae in patients treated for leishmaniasis

A leishmaniose pode destruir os tecidos nasais resultando em alterações da via lacrimal excretora. OBJETIVO: Avaliar a ocorrência de alterações do sistema lacrimal excretor em portadores de leishmaniose na fase de pós-tratamento. MÉTODOS: Foi realizada a avaliação da via lacrimal excretora em 45 portadores de leishmaniose tratada (90 vias lacrimais) pelo teste de Jones I. Treze pacientes (26 ductos nasolacrimais) tiveram o teste de Jones I alterado, tendo sido submetidos a dacriocistografia e endoscopia nasal. RESULTADOS: A maioria dos indivíduos avaliados apresentava a leishmaniose na forma cutânea (64,4%). Entretanto, 69,23% dos indivíduos com alteração do sistema lacrimal excretor apresentavam a forma mucocutânea antes do tratamento. A alteração mais freqüentemente detectada foi ducto nasolacrimal permeável e dilatado (92,30%). Apenas 3,84% (1/26) das vias lacrimais estavam obstruídas. A endoscopia nasal mostrou hipertrofia de corneto (53,84%), desvio de septo (53,84%) e perfuração do septo nasal (23,07%). CONCLUSÃO: em portadores de leishmaniose tratada encontra-se como seqüela mais freqüente no sistema excretor lacrimal as vias lacrimais permeáveis e dilatadas.

Composition and quantification of the anthropogenic and natural fractions of wastes collected from the stormwater drainage system for discussions about the waste management and people behavior

A study was made of the composition of wastes collected from the pipes of the stormwater drainage system of Sorocaba, SP, Brazil (600 thousand inhabitants). A total of 10 samples weighing at least 100 kg each were sorted into 19 items to determine the fraction that can be considered natural (earth/sand, stones, organic matter, and water, the latter determined after oven-drying the samples) and the anthropogenic fraction (the remaining 15 items, especially construction and demolition wastes and packaging). Soil/sand was found to be the main item collected (52.5 % dry weight), followed by the water soaked into the waste (24.3 %), which meant that all the other wastes were saturated in mud, whose contents varied from 6.4 % (glass) to 87.2 % (metalized plastics packaging). In general, 83 % of the collected wastes can be classified as natural, but the remaining 17 % represent 2,000 kg of the most varied types of wastes discarded improperly every day on the streets of the city. This is an alarming amount of wastes that may clog parts of the drainage systems, causing troubles for all the population (like flooding) and must be strongly considered in municipal solid wastes management and in environmental education programs. © 2013 Springer Science+Business Media Dordrecht.

Evaluation of lacrimal system outflow in the newborn by dye tests

PURPOSE: The aim of this study was to evaluate the outflow from the lacrimal excretory system (LES) at birth. METHOD: Two-hundred LES were evaluated by the Milder Test (DDT) and the modified Jones I Test (JIT) in 100 newborns (NBs) from 31 (T 1) until 42 (T 3) weeks of gestational age. The occurrence of obstruction was related to sex, weight at birth, presence of ocular discharge and the degree of maturity. RESULTS: Both tests were in agreement and showed LES obstruction in 61.5% (DDT) and 78.5% (JIT), respectively, while the LES outflow increased with increasing maturity. CONCLUSION: Evaluation of LES outflow at birth reveals obstruction rates that are much higher than those clinically observed in children with complaints of epiphora.

Comprometimento da pálpebra e via lacrimal excretora em portador de leishmaniose cutâneo-mucosa: relato de caso

Objetivo: Apresentar um portador de leishmaniose com lesão palpebral e dilatação de via lacrimal excretora. Relato de caso: O paciente em questão foi portador de leishmaniose do tipo cutâneo-mucosa, tendo apresentado múltiplas lesões de pele, ectrópio da pálpebra inferior, lesões na mucosa nasal e alterações na drenagem lacrimal. Discussão: O acometimento da pálpebra e da via lacrimal raramente ocorre em portadores de leishmaniose. Os autores chamam atenção para o diagnóstico e para a necessidade de se adotar medidas preventivas contra os vetores e a rápida instituição do tratamento.

Massa paranasal: dacrioestenose congênita? Relato de caso

O objetivo deste é descrever uma criança portadora de massa paranasal, atentando para a importância dos diagnósticos diferenciais. RELATO do CASO: ACS, 6 meses, sexo feminino, desde o nascimento apresentando abaulamento não inflamatório, no canto medial do olho esquerdo, lacrimejamento e hiperemia no olho direito. Ao exame apresentava fenômeno de Bell negativo bilateral, lagoftalmo à direita, ulceração e opacidade corneana à direita; presença de lesão arredondada, de superfície lisa no canto medial do olho esquerdo, sem sinais inflamatórios, medindo aproximadamente 2 cm de diâmetro, não pulsátil. À palpação, a lesão era elevada, de consistência fibroelástica, imóvel, indolor, irredutível. À propedêutica das vias lacrimais, não havia refluxo à compressão, o teste de Milder foi negativo em ambos olhos e as vias apresentavam-se pérvias à dacriocistografia. O exame tomográfico revelou tratar-se de meningocele fronto-etmoidal. COMENTÁRIOS: Os autores chamam a atenção para a adequada semiologia para a investigação das massas paranasais, a fim de se instituir o adequado tratamento.

Morfometria de microbacias do Córrego Rico, afluente do Rio Mogi-Guaçu, Estado de São Paulo, Brasil

Este trabalho teve como objetivo avaliar as características morfométricas das microbacias (2ª, 3ª, 4ª e 5ª ordens de magnitude) da bacia hidrográfica do córrego Rico, sub-bacia do Rio Mogi-Guaçu, localizada na região administrativa de Ribeirão Preto, Estado de São Paulo, Brasil. Para tanto, foram determinados os parâmetros físicos e a configuração topográfica natural do sistema de drenagem. Os procedimentos para a obtenção dos dados foram fundamentados em técnicas de sensoriamento remoto e geoprocessamento. A partir da vetorização das cartas topográficas correspondentes à área de estudo, realizou-se a análise morfométrica quanto às características dimensionais, do padrão de drenagem e do relevo no sistema de informação geográfica ArcView. A microbacia é considerada de sexta ordem de magnitude, com área estimada de 542 km², com 85 microbacias de segunda ordem, 22 de terceira, sete de quarta ordem e duas de quinta. Utilizando o critério geométrico, na disposição fluvial das sub-bacias de cabeceiras observou-se a predominância dos modelos dendríticos e subdendríticos, enquanto a jusante predominava o modelo subparalelo, respectivamente, nas áreas de ocorrências dos arenitos Bauru e rochas efusivas básicas.

Persistent Pleuropulmonary Air Leak Treated with Autologous Blood: Results from a University Hospital and Review of Literature

Background: Persistent air leak after pulmonary resection is a difficult complication for thoracic surgeons to manage. Objectives: To show the results of our experience treating persistent pleuropulmonary air leak with autologous blood and review the literature on this specific method of treatment. Methods: Retrospective study of patients with persistent aerial pleuropulmonary fistula treated with autologous blood. The patient's own blood was collected from a peripheral vein and directly introduced through the pleural drain. An inverted siphon was located in the drainage system to avoid prolonged clamping of the drain. This siphon impeded blood return but not air escape. Results: Between January 2001 and August 2008, 27 patients were treated by the above method. Patient age ranged from 2 to 74 years, and 78% were male. Each procedure used a mean quantity of 92 ml blood. Mean persistent air leak time before pleurodesis was 10.6 days and mean time to fistula resolution after pleurodesis was 1.5 days. Twenty-three (85%) patients had persistent pleuropulmonary air leak closed with the above procedure. Conclusion: Treating persistent pleuropulmonary air leak with autologous blood is promising, but further studies are required to quantify its real effectiveness. Copyright (C) 2009 S.

Epidemiological aspects in leptospirosis. Research of anti-Leptospira spp antibodies, isolation and biomolecular research in bovines, rodents and workers in rural properties from Botucatu, SP, Brazil.

Leptospirosis is a worldwide infection, transmitted between man and animals that causes a decrease in the production of bovine flocks, and offer risks for public health, as an important zoonosis. The rodents are the main reservoirs of leptospires. It was studied 27 dairy farm properties located in or near from Botucatu-SP, Brazil. In these farms were collected blood and kidney samples from rodents, blood and urine samples from bovines and blood samples from the workers. The serology was performed with microscopic agglutination test (MAT). Samples of bovine urine and rodent kidneys were cultivated searching for leptospires isolation. The polymerase chain reaction (PCR) of the kidneys of the rodents was performed. In MAT, 46/ 140 (32.85%) bovine and 8/34 (23.53%) human sera samples were positive, respectively. In human samples, the serovar Brastilava (37.51%) presented the highest occurrence, while in bovines, the serovars Hardjo and Castellonis were most frequent, with 26.08% each one. All of the rodents were negatives in serology. No leptospire was isolated, and kidney samples were negative in PCR. In bovines, the dam water and the bad hygiene quality of milking process were considered important risks of infection in the affected properties (p<0.05), where other reproductive problems, except abortion, can be related. In other side, to human beings the drainage system was the most important risk factor in the studied properties. Thus, it was verified the necessity of an improvement in zoosanitary handling of the properties, mainly of water supply.
