Tineabarbae is a rare form of dermatophytosis that affects hair follicles of the beard and moustache. Dermoscopy could prove useful to identify parasitism of hair of the beard, just as it has proven useful in the diagnosis of Tineacapitis. We present the first fully documented case series of T. barbae with clinical, dermoscopic and mycological features.

INTRODUCTION: Clinical expression of psoriasis is in part dependent on external factors, such as drugs, microorganisms or stress. However convincing evidence of the role of Malassezia species in the pathogenesis of the psoriasis is still lacking. PATIENTS AND METHODS: Samples taken from scalp skin of 40 psoriatic patients and the same number of healthy individuals were observed under direct microsocopic examination and cultured on modified Dixon agar. RESULTS: Direct microscopy examination of psoriatic scalp scales was positive in 30 (75%) patients; while it was positive in only 12 (30%) healthy subjects (P=0.003). Half of the cultures from healthy subjects showed no growth of colonies, but only 8 (15%) of psoriatic patients were negative. When an exacerbation has occurred in the previous weeks, pseudohyphaes were observed in 12 (40%) patients, Malassezia globosa was isolated in 18 (45%) patients and Malassezia restricta was isolated in 12 (30%) patients. In the group of patients having stable lesion, without any exacerbation in the previous weeks, no pseudohypahes were observed, M. globosa was not isolated, M. restricta was isolated in 4 (10%), and cultures were negative in 6 of them (15%). CONCLUSIONS: Malassezia species form an integral part of normal cutaneous microflora in humans, however we found that during the episodes of exacerbation of the disease the presence of these yeasts, and particularly M. globosa, was increased.

Histoplasmosis is a fungal infection caused by a dimorphic fungus, Histoplasma capsulatum. Most infections occur after inhalation of fungal spores. A wide variety of clinical manifestations can occur depending on the host response and the extent of inoculation. We report a case of probable cutaneous histoplasmosis after trauma in a 26-year-old man from Paraguay who was also infected with the human immunodeficiency virus. Diagnosis was based on histological and mycological examination. No systemic involvement was found.

INTRODUCTION: Knowledge of the dangers of sun exposure does not always lead to changes in behavior. Failure to make behavioral adjustments is of particular concern in high-risk patients. OBJECTIVES: a) To assess the impact of melanoma diagnosis on knowledge, attitudes, and behaviors relating to sun protection, and b) to identify factors that could influence sun protection behaviors. METHODS: A coded, anonymous questionnaire was given to 195 patients with a recent diagnosis of melanoma. Data were collected on clinical and demographic variables and on knowledge, attitudes, and behaviors relating to sun protection before and after diagnosis. The questionnaire also addressed patients' sense of distress and guilt following diagnosis. RESULTS: Sun protection behaviors improved following diagnosis in 66% of patients. Although 98% of patients reported having received advice on sun protection following diagnosis, 15% continued to take inadequate sun protection measures. The probability of behavioral improvement following diagnosis was 4 times greater in women than in men. The subgroup of patients whose behavior improved had worse behaviors prior to diagnosis than did those who showed no improvement. Patients who expressed distress and feelings of guilt following diagnosis were more likely to improve their sun protection behavior. Age, tumor site, intensiveness of treatment, and belief that a suntan is healthy had no significant influence on behavioral change. CONCLUSIONS: Melanoma diagnosis is associated with increased knowledge of sun protection measures and improvement in behaviors. Nevertheless, patients continue to use inadequate sun protection measures. Identification of barriers to optimal sun protection behavior may be instrumental in designing targeted educational campaigns.

Introducción: El conocimiento sobre los peligros de la exposición solar no siempre se traduce en cambios en el comportamiento. Esto es particularmente alarmante en pacientes de alto riesgo. Objetivos: a) Evaluar el impacto del diagnóstico de melanoma en los conocimientos, actitudes y hábitos sobre fotoprotección, y b) analizar qué factores pueden influir en el cambio de hábitos de fotoprotección. Métodos: Usando un cuestionario anónimo y codificado que recogía datos clinicodemográficos, 195 pacientes con reciente diagnóstico de melanoma fueron interrogados sobre los conocimientos, hábitos y actitudes sobre fotoprotección antes y después del diagnóstico y sobre los sentimientos de angustia y culpabilidad tras el mismo. Resultados: El 66% de los pacientes optimizó su conducta tras el diagnóstico. Un 15% mantuvo conductas deficientes, a pesar de que el 98% de los sujetos refería haber recibido consejos de fotoprotección tras el diagnóstico. Las mujeres optimizaron su conducta 4 veces más que los hombres. El subgrupo de pacientes que mejoró presentaba conductas más deficientes que el subgrupo que no mejoró. Aquellos que experimentaron sentimientos de angustia y culpa tras el diagnóstico presentaron mayor probabilidad de optimizar su conducta. La edad, la localización tumoral, la agresividad terapéutica y la creencia de que el bronceado es saludable no tuvieron influencia significativa en la modificación de la conducta. Conclusión: El diagnóstico de melanoma lleva consigo un aumento en los conocimientos y un cambio favorable en los hábitos de fotoprotección. A pesar de ello, las medidas de fotoprotección no son lo suficientemente adecuadas. La evaluación de las barreras hacia la fotoprotección óptima puede ser la clave para diseñar programas educacionales específicos (AU)
