Abstract: BACKGROUND: Patients with oral sensitivity are common in our practice. Allergic contact dermatitis is one of the most frequent etiologies. OBJECTIVES: Evaluate oral contact dermatitis using the Brazilian standard series and complementary dental series in patients using dental prostheses, with or without oral complaints. Determine specific dental Brazilian series. METHODS: Patients using dental prostheses with or without oral complaints realized patch tests. Brazilian standard series and complementary dental series were used according to ICDRG recommendations. The results were analysed according to age, sex, race, atopic conditions and symptoms associated. RESULTS: From 54 patients tested, 34 (63%) were positive at least to one substance. Nineteen had oral complaints, such as burning mouth, itch or oral erythema. There was no association between atopic condition and tests results. Without the oral series, just 23(42,6%) patients had a positive result. Using the Brazilian standard series with the complementary dental series we improved the positivity of the patch test to 47%. CONCLUSION: In patients using prostheses and with oral complaints, patch tests with Brazilian standard series with complementary dental series improve the tests positivity.

Abstract Darier’s disease is characterized by dense keratotic lesions in the seborrheic areas of the body such as scalp, forehead, nasolabial folds, trunk and inguinal region. It is a rare genodermatosis, an autosomal dominant inherited disease that may be associated with neuropsichiatric disorders. It is caused by ATPA2 gene mutation, presenting cutaneous and dermatologic expressions. Psychiatric symptoms are depression, suicidal attempts, and bipolar affective disorder. We report a case of Darier’s disease in a 48-year-old female patient presenting severe cutaneous and psychiatric manifestations.

FUNDAMENTOS: As micotecas são coleções de fungos conservadas para estudo futuro ou para a obtenção de extratos, drogas e outros fins. A conservação em meios de cultura por repiques sucessivos exige cuidados e nem sempre é fácil. Há necessidade de novas técnicas para a manutenção de fungos viáveis por longos períodos. OBJETIVO: avaliar a eficácia da preservação de fungos em água destilada num período de 12 meses. MÉTODOS: 43 espécies de fungos foram mantidas em frascos de vidro com água destilada estéril. Mensalmente eram colhidos de 200 a 250mil do líquido e inoculado em ágar batata dextrose para avaliar o crescimento e viabilidade dos fungos. RESULTADOS: houve crescimento dos fungos em todos os meses pelo período de um ano. CONCLUSÕES: A preservação de cepas pelo método da água destilada possibilitou, nesse curto espaço de tempo, provar a viabilidade e a capacidade de esporulação das cepas submetidas ao estudo. A conservação de fungos em água destilada é método barato e prático para manutenção de micoteca.

BACKGROUND: Mycology collections are used to preserve fungi for future studies or to obtain extracts, drugs and others. Fungal preservation in culture media by successive sampling requires care and is not always easy. Novel techniques are necessary to maintain viable fungi for longer periods. OBJECTIVE: To evaluate the efficacy of preservation of fungi in distilled water for 12 months. METHODS: 43 species of fungi were maintained in glass flasks with sterile distilled water. Two hundred to 250 _l of the liquid were monthly collected and inoculated in potato dextrose agar to evaluate growth and viability of the fungi. RESULTS: All fungi grew every month during one year. CONCLUSIONS: reservation of fungal strains in distilled water allowed, in a short time interval, to prove viability and sporulation capacity of the fungi. Preservation of fungi in distilled water is a cheap and practical method to maintain a mycology collection.

Os autores relatam um caso de ceratodermia palmoplantar hereditária de Unna-Thost, de apresentação clínica atípica, bem como complicação do tipo estrangulamento ainhumóide no quinto dedo de ambos os pés. Os autores citam ainda outras ceratodermias palmoplantares hereditárias que podem cursar com pseudo-ainhum, bem como os critérios clínicos básicos que diferenciam essas manifestações.

The authors report a case of hereditary palmoplantar keratoderma, Unna-Thost type, demonstrating some atypical features when compared to descriptions found in the literature. The case study also includes pseudoainhum on both fifth toes. The authors describe other hereditary palmoplantar keratodermas that may also present with pseudoainhum, and demonstrate the basic clinical criteria that they share.
