ABSTRACT

OBJETIVOS: reportar los resultados de la estrategia que incluye "el tratamiento tópico con azufre precipitado al 6% sumado a medidas no farmacológicas" en la población de Villa Verde, Pilar, Buenos Aires, Argentina. MÉTODOS: Serie de casos tratados entre Marzo de 2007 y marzo de 2008 de una muestra de conveniencia integrada por toda la población con signos y síntomas sugestivos de escabiosis durante dicho período. RESULTADOS: Fueron incluidos 161 pacientes, pero sólo se pudo realizar la evaluación completa en 110 de ellos (68,3%). De éstos, 74 se encontraba curado a los 15 días de iniciado el tratamiento y otros 23, al mes, lo que implica una tasa global de curación de 88%. Sólo 12,7% de la muestra evaluada presentó efectos adversos. El 20% de los encuestados percibió la intervención como de bajo costo, el 32,6 de costo moderado y el 47,5 alto. El autorreporte de adherencia al tratamiento farmacológico fue de 95% y del no farmacológico, 96%. CONCLUSIONES: Estos resultados contribuyen a avalar una estrategia terapéutica ampliamente utilizada en nuestro medio (por su bajo precio y amplia disponibilidad), que por el momento posee escasa evidencia científica y es utilizada por motivos fundamentalmente empíricos.


OBJECTIVES: Report the results of the strategy that includes "the topical treatment with precipitated sulfur at 6% plus non-pharmacological measures" in the population of Villa Verde, Pilar, Buenos Aires, Argentina. METHODS: A series of cases treated between March 2007 and March 2008 of a sample of convenience integrated by the entire population with signs and symptoms suggestive of scabies during this period. RESULTS: A total of 161 patients were included, but only 110 of them could complete the complete evaluation (68.3%). Of these, 74 were cured 15 days after starting treatment and another 23, a month, which implies an overall cure rate of 88%. Only 12.7% of the sample evaluated had adverse effects. 20% of respondents perceived the intervention as low cost, 32.6 moderate cost and 47.5 high. Self-reported adherence to pharmacological treatment was 95% and non-pharmacological self-report was 96%. CONCLUSIONS: These results contribute to endorse a therapeutic strategy widely used in our environment (due to its low price and wide availability), which at the moment has little scientific evidence and is used for fundamentally empirical reasons.

ABSTRACT

Neste trabalho descreve-se surto de polioencefalomalacia em bovinos decorrente da ingestão de dieta com excessiva concentração de enxofre em uma propriedade no Rio Grande do Sul. O lote era composto por 30 bezerros, mantidos em um piquete com azevém (Lolium multiflorum) e suplementados com ração e sal mineral. Seis bezerros morreram e dois deles foram necropsiados; amostras de tecido hepático para dosagem de chumbo e fragmentos do sistema nervoso central para histopatológico foram colhidos. Um dos bezerros foi examinado antes da morte e sinais neurológicos encefálicos foram constatados. Foi estabelecido o teor de enxofre nos componentes da dieta e água, a produção de sulfeto de hidrogênio ruminal em cinco bovinos do mesmo lote e realizada PCR de um bloco de parafina para detecção de DNA do herpevirus bovino tipo 5. O consumo total de enxofre foi de 0,38 por cento da matéria seca fornecida aos animais e as dosagens de sulfeto de hidrogênio ruminal em animais do mesmo lote variaram de 1.000 a 2.500ppm. Os achados histopatológicos indicaram necrose laminar do córtex cerebral. Não foi detectado chumbo na amostra de tecido hepático e não foi identificado DNA do herpesvirus bovino tipo 5 no encéfalo. O quadro clínico de síndrome cerebrocortical associado aos elevados valores do sulfeto de hidrogênio ruminal, alta ingestão de enxofre na dieta e os achados histopatológicos permitem estabelecer o excesso de enxofre como causador da polioencefalomalacia.


An outbreak of polioencephalomalacia in cattle caused by ingestion of high sulphur diet, in Rio Grande do Sul, Brazil is described. One group of 30 calves was kept in Italian ryegrass (Lolium multiflorum) pasture and supplemented with concentrate and minerals. Six calves died, necropsy was performed in two of them and liver samples (for lead determination) and fragments of central nervous system were collected. Clinical and neurological examination was performed in one calf and confirmed brain involvement. Sulphur content on dietary components and water, ruminal hydrogen sulfide production in five calves of the same group and PCR from formalin-fixed paraffin-embedded cerebral tissues to detect bovine herpesvirus 5 DNA was perfomed. The total sulphur intake was 0.38 percent dry matter and the values of ruminal sulfide concentration ranged from 1,000 to 2,500ppm. Lead It was not detected in the liver samples and PCR was negative for bovine herpesvirus 5. The brain lesions were characterized by laminar neuronal necrosis. The clinical signs of cerebrocortical syndrome associated with high ruminal sulfide values, elevated intake of dietary sulphur and histological lesions confirmed that the excess of sulphur caused the polioencephalomacia in these calves.
