This study was undertaken to investigate human leucocyte antigen (HLA) associations with benign migratory glossitis and psoriasis in Brazilian patients and particularly to determine whether benign migratory glossitis is also associated with HLA-Cw6, the classical association observed in psoriasis. The results showed a highly significant association of Cw6 with both psoriasis and benign migratory glossitis, with this antigen being present in 59.1% of the patients with psoriasis, in 43.8% of the patients with benign migratory glossitis, and in only 12.6% of the controls. Other significant positive associations, although at a lower significance level, were with B13, both in psoriasis and in benign migratory glossitis, and with B17, only in psoriasis. To our knowledge, this is the first report on the association of Cw6 with benign migratory glossitis. We believe that this finding reinforces the concept of a pathogenetic relationship between benign migratory glossitis and psoriasis.
Oral treatment with ivermectin of crusted (Norwegian) scabies in two immunosuppressed patients is reported. There was resolution of symptoms and signs of the cutaneous parasitosis on administration of 18-36 mg ivermectin (total doses) in 2- and 3-week periods of treatment, with remission periods of 3 and 4 months, respectively.
FUNDAMENTOS: A relação entre acne vulgar, alimentação e terapia com ácidos graxos essenciais é desconhecida, embora esses elementos tenham papel importante na fisiopatogenia dessa dermatose. OBJETIVO: Verificar a resposta clínica da acne vulgar com o uso de ácidos graxos essenciais e quais os melhores métodos de avaliação do tratamento. MÉTODOS: Trinta e um voluntários, dos quais 16 (51,6%) receberam esquema oral rico em ácidos graxos essenciais e 15 receberam placebo (48,4%). Foram utilizadas análises clínica, de auto-avaliação, digital e histológica para avaliação. RESULTADOS: Não houve diferença nas notas subjetivas (p=0,419) e na análise digital (p=0,2187) entre os gupos placebo e produto; houve sugestão de melhora com o uso do produto, pela histopatologia (p=0,087), sem significância pelo teste do qui-quadrado (= 4,878); ausência de correlação estatística entre a análise digital e a nota subjetiva dos voluntários (p=0,127), entre a nota subjetiva e a resposta histopatológica (p=0,438); houve, porém, relação entre a análise histopatológica e a digital (p=0,012). CONCLUSÕES: 1) Para se avaliar o benefício clínico deve-se realizar um estudo com amostra maior; 2) a auto-avaliação do voluntário e a análise digital não puderam discernir o melhor padrão terapêutico para acne vulgar, se medicamento ou placebo; 3) a associação histopatologia-análise digital parece ser a melhor forma de avaliação da qualidade da resposta clínica dessa terapêutica; 4) a histopatolgia parece ser o método mais sensível para avaliar essa modalidade terapêutica.
To determine the incidence of tinea capitis in São Paulo, Brazil, an investigation was performed in Private and Public Pediatrics Service involving 4,500 children from 0 to 15 years old during 5 years (1996-2000). Samples were taken from 132 children with suspected fungal infection of the scalp, for direct microscopy and culture. Tinea of scalp was mycologically confirmed in 112 patients (85%). Males were more affected than females in all age groups. Children below 8 years old accounted for more than 75% of the occurrences. Only three cases of tinea capitis were diagnosed in children from 12 to 15 years of age. Tinea capitis was prevalent in 103 cases (91.96%); inflammatory kerion type lesions were diagnosed in 9 patients (8.04%). Microsporum canis (70.5%) and Trichophyton tonsurans (23.2%) were the most common agents followed by T. mentagrophytes (3.6%), M. gypseum (1.8%) and T. rubrum (0.9%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
