BACKGROUND: Androgenetic alopecia is the most common form of hair loss. It is a clinical entity of relevant interest and presents a significant psychosocial impact as it undermines self-esteem and quality of life in female patients due to the importance of the hair for people's facial balance. OBJECTIVE: The purpose of the present study is to evaluate dermoscopic signs in women clinically diagnosed with androgenetic alopecia. METHOD: Observational study with 34 women between 17 and 68 years old who were diagnosed with androgenetic alopecia. All of them underwent photographic sessions with a 10x magnification dermoscope and a digital camera zoom set to 20x magnification and 40x magnification on the scalp frontal midline. RESULTS: All patients showed miniaturization. A peripilar brown halo was found in 22 patients, honeycomb-like scalp pigmentation was found in 14 and yellow dots in only 1 patient. Recent studies show dermoscopy as the new tool for diagnosis assistance and treatment follow up in scalp disorders. Our study used an ordinary dermoscope and we evaluated several findings reported in the literature with significant clarity and easiness. CONCLUSION: The dermoscope, which is used by dermatologists on a daily basis, is an excellent tool to assist in early diagnosis and assessment of therapeutic response in androgenetic alopecia. Keywords: Alopecia; Dermoscopy; Miniaturization Resumo: FUNDAMENTOS: Alopecia androgenética é forma mais comum de queda de cabelo. Constitui entidade clí-nica de interesse relevante e acarreta grande impacto psicossocial por comprometer a auto-estima e a qualidade de vida das pacientes. OBJETIVO: Procurar os sinais dermatoscópicos comuns em mulheres com diagnóstico clínico de alopecia androgenética, visando diagnóstico precoce e melhor resposta terapêutica. MÉTODOS: Estudo observacional em 34 mulheres com idades entre 17 e 68 anos, com diagnóstico clínico de alopecia androgenética. Todas pacientes foram avaliadas e submetidas a registros fotográficos com o dermatoscópio no aumento de 10x e câmera digital no aumento de 20x e 40x na linha média frontal do couro cabeludo. RESULTADOS: Todas as pacientes apresentaram miniaturização dos fios na área examinada. Halo castanho peripilar foi encontrado em 22 pacientes, pigmentação em favo de mel em 14 e pontos amarelos em apenas 1 paciente. Estudos recentes mostram a dermatoscopia como uma nova ferramenta no auxílio diagnóstico e acompanhamento do tratamento das desordens do couro cabeludo. Em nosso estudo utilizamos um dermatoscópio comum e avaliamos vários achados relatados na literatura com facilidade e clareza significativas. CONCLUSÃO: O dermatoscópio, instrumento de uso diário dos dermatologistas, é excelente ferramenta para auxí-lio no diagnóstico precoce e avaliação da resposta terapêutica na alopecia androgenética e é capaz de mostrar de forma simples sinais precoces de miniaturização capilar.
We report four cases of scalp white piedra (SWP) in Brazilian female children. Morphological and physiological approaches gave inconsistent results for identifying Trichosporon to species level, while the sequencing of the intergenic spacer 1 region of ribosomal DNA accurately identified the agent of SWP as T. inkin. These cases emphasize the occurrence of this species causing this type of infection. The molecular identification of the suspected agent is needed for appropriate epidemiological surveillance of superficial mycoses caused by Trichosporon species.
relAto de cAso cAse rePort INTRODUÇÃO A síndrome de Felty (SF) compreende a tríade de artrite reumatóide (AR), neutropenia e esplenomegalia, ocorrendo em menos de 1% dos pacientes com AR. A faixa etária predominante é da quinta a sétima década, sendo dois terços dos pacientes mulheres. (1,2,3) Ocorre em pacientes portadoras de AR de longa evolução, com importante destruição articular e pouca ou nenhuma inflamação, além de manifestações extra-articulares exuberantes, como nódulos subcutâneos, úlceras de membros inferiores (MMII), linfadenopatia, vasculites e neuropatia periférica. Encontra-se fator reumatóide (FR) em altos títulos em 95% dos casos (4). A esplenomegalia é de tamanho variável, não sendo essencial para o diagnóstico (5) .
Primary hyperparathyroidism is a disease caused by exaggerated secretion of the parathyroid gland hormone, produced by an adenoma in 80% of cases. Ectopic adenomas occur in a small proportion of cases. Herein, the authors report a 72-year-old woman with a delayed diagnosis of primary hyperparathyroidism, produced by an intrathoracic adenoma, with a longstanding course, presenting with severe osteoporosis, multiple fractures, bone deformities, and neurologic impairments. Persistent hypercalcemia, high levels of alkaline phosphatase, and parathyroid hormone were documented and a paratracheal mass was found on a helicoidal tomography of the thorax. After surgical removal, the histopathological examination confirmed an ectopic adenoma of the parathyroid gland and the patient achieved some improvement in her clinical picture.
