RESUMEN
ABSTRACT Piedras are small nodules found on the hair shafts. White piedra was initially described as caused by Trichosporon beigelii, which was later reclassified in several species. We describe the first case of white piedra caused by Cutaneotrichosporon debeurmannianum. Affected hairs were examined in natura with scanning electron microscopy, after gold metallization. The typical whitish cerebriform creamy colony was obtained in Sabouraud medium. Fungal genomic DNA extracted from cultures and locus was amplified with the NL1/NL4 primer pair from the D1/D2 region of the large ribosomal subunit (LSU) of 28S rRNA. With scanning electron microscopy, nodules are easily identified surrounding the hair shaft; with high magnifications, rounded structures adhered to each other were identified. Comparison of the nucleotide sequences of IMT-1703 Cutaneotrichosporon debeurmannianum revealed 99.6% similarity with the 28S large ribosomal unit rDNA sequence. This case of white piedra was caused by Cutaneotrichosporon debeurmannianum.
RESUMEN
Introdução: O envelhecimento e o aumento da ocorrência de excesso de peso na população brasileira têm propiciado considerável aumento na prevalência de diabetes mellitus (DM). O estudo objetivou verificar e aumentar a efetividade do cuidado oferecido aos indivíduos com DM por meio de estudo do tipo antes e depois. Métodos: Foram realizados dois inquéritos epidemiológicos rápidos nas zonas de abrangência da UBS Areal Leste com Estratégia Saúde da Família (ESF). Foram implementadas medidas de intervenção entre as duas coletas, constituindo-se em um estudo do tipo antes-depois. Foram incluídos ambos os sexos acima de 40 anos de idade com diagnóstico de diabetes mellitus. Resultados: Foram encontradas diferenças nos intervalos de confiança em relação ao exame dos pés diabéticos e instruções sobre atividade física. Conclusão: A melhora constatada no exame dos pés nos pacientes que consultavam na unidade provavelmente foi resultado da intervenção. Os resultados mostraram deficiências e fortalezas do serviço, esperando-se a manutenção dos indicadores positivos e a superação dos resultados negativos.
Introduction: The aging and the increased occurrence of overweight in the Brazilian population have led to a considerable increase in the prevalence of diabetes mellitus (DM). The study aimed to verify and increase the effectiveness of the care provided to individuals with DM through a before-and-after study. Methods: The study conducted two rapid epidemiological surveys in the area covered by UBS Areal Leste with Family Health Strategy (FHS). Intervention measures were implemented between the two surveys, constituting a before-after study. The sample included men and women, over 40 years old, diagnosed with diabetes mellitus. Results: It presented differences in confidence intervals regarding diabetic foot examination and instructions on physical activity. Conclusion: The improvement seen in foot examination in patients consulting in the unit was probably a result of the intervention. The results showed deficiencies and strengths of the service, expecting to maintain the positive indicators and overcome the negative results.
