RESUMO Objetivo: Avaliar a associação da imagem corporal com o nível de atividade física, composição corporal e o comportamento sedentário de adolescentes do sexo feminino. Métodos: Estudo transversal e exploratório com 120 adolescentes do sexo feminino, de 14 a 19 anos, de Viçosa, MG. A imagem corporal foi avaliada por uma Escala de Silhuetas e pelo Body Shape Questionnaire (BSQ). O peso, a estatura e o perímetro da cintura foram aferidos, avaliando-se a relação cintura estatura e o percentual de gordura corporal. O nível de atividade física (NAF) foi avaliado pelo Recordatório de Atividade Física de 24h (R24h) e o comportamento sedentário, pelo tempo em frente à tela de uma TV, jogando videogame, ao computador e usando tablets e, separadamente, o tempo de tela ao celular. Resultados: A média de idade foi 16,5±1,5 anos, sendo a maioria das participantes eutróficas (77,6%), sedentárias/baixo NAF (84,2%), com tempo de tela (85,2%) e tempo de celular (58,7%) elevados. A insatisfação corporal manifestou-se em 40,6% pelo BSQ e em 45,8% pela Escala de Silhuetas. A distorção corporal manifestou-se em 52,9% das participantes. As medidas de composição corporal, juntamente com o tempo ao celular e o NAF, mostraram associação com a insatisfação corporal, sendo as adolescentes mais ativas as mais insatisfeitas. Conclusões: O estudo mostrou que as adolescentes com maior tempo ao celular tinham maior insatisfação corporal, assim como as fisicamente mais ativas. Todas as medidas de avaliação da composição corporal mostraram-se associadas ao nível de insatisfação, principalmente o índice de massa corporal, perímetro da cintura e relação cintura-estatura.

ABSTRACT Objective: To evaluate the association of body image with physical activity level, body composition, and sedentary behavior (SB) of female adolescents. Methods: Exploratory cross-sectional study conducted with 120 female adolescents aged between 14-19 years, from the city of Viçosa, Minas Gerais, Southeast Brazil. Body image was evaluated with a Body Silhouette Scale (BSS) and a Body Shape Questionnaire (BSQ). Weight, height, and waist circumference values were analyzed, as well as the waist-to-height ratio and body fat percentage. The physical activity level (PAL) was assessed by 24-hour Physical Activity Recall and SB by screen time, that is, time spent in front of a TV, playing video game, on the computer and using tablets, and, separately, the cell phone time. Results: Mean age was 16.5±1.5 years, and most adolescents were eutrophic (77.6%), sedentary/low PAL (84.2%), with high screen time (85.2%) and cell phone time (58.7%). Body dissatisfaction was stated in 40.6% of BSQ and 45.8% of BSS evaluations. Body distortion was identified in 52.9% of participants. All body composition measures, along with cell phone time and PAL, were associated with body dissatisfaction, the more active adolescents presenting higher levels of dissatisfaction. Conclusions: This study concluded that female adolescents with higher cell phone time also present higher body dissatisfaction, as well as the most physically active ones. All body composition measurements were associated with body dissatisfaction, mainly body mass index, waist circumference, and waist-to-height ratio.

Abstract INTRODUCTION: The drugs available for visceral leishmaniasis (VL) treatment in Brazil have specific characteristics in terms of operability, effectiveness, toxicity, and cost. The aim of this study was to estimate the direct costs of therapies recommended by the Ministry of Health (MH) for VL treatment in Brazil. METHODS: The analytical perspective used was that adopted by the Brazilian Public Health System. Three drugs and four regimens were included: 1) N-methyl glucamine antimoniate intramuscularly at 20mg per kg per day for 30 days; 2) N-methyl glucamine antimoniate intravenously at 20mg per kg per day for 30 days; 3) amphotericin B deoxycholate at 1mg per kg per day for 21 days; and 4) liposomal amphotericin B at 3mg per kg per day for a 7 days treatment. RESULTS: The estimated direct costs of treatment for an adult patient using N-methylglucamine antimoniate administered via the intramuscular and intravenous routes were USD 418.52 and USD 669.40, respectively. The estimated cost of treatment with amphotericin B deoxycholate was USD 1,522.70. Finally, the estimated costs of treatment with liposomal amphotericin B were USD 659.79, and USD 11,559.15 using the price adopted by the WHO and the Drug Regulation Board, respectively. CONCLUSIONS: This analysis indicates the economic feasibility of replacing N-methyl glucamine antimoniate with liposomal amphotericin B, which allows a shorter treatment period with less toxicity compared with other treatments, provided that the purchase value used by the WHO and transferred to the MH is maintained.

Abstract We report a case of nevus lipomatosus cutaneous superficialis of Hoffman-Zurhelle (NCLS), with multiple lesions, in a ten-year-old child. The NLCS is considered rare. The classical clinical presentation is characterized by multiple skin-colored or yellowish papules and nodules, which can have a linear distribution. Histologically, it is characterized by the presence of mature ectopic adipocytes in the dermis. The main therapeutic option is surgical excision. The classical Nevus lipomatosus cutaneous superficialis is reported in this case.

Abstract: Dermatofibroma is a frequent benign tumor of easy clinical diagnosis in most cases, but that can mimic other dermatoses. Dermoscopy may help to define the diagnosis and its classical pattern is a central white area, similar to a scar, surrounded by a discrete pigment network. However, dermoscopic findings are not always typical. We describe here a case of dermatofibroma exhibiting ridges, furrows and pseudocomedos, a pattern which is typical of seborrheic keratosis, in dermoscopy.

O líquen plano é uma enfermidade pouco frequente na infância, apenas 2 a 3% dos pacientes acometidos se encontram abaixo dos vinte anos de idade. Essa dermatose pode se apresentar sob várias formas clínicas, as quais variam de acordo com a morfologia e distribuição das lesões. Em menos de 0,2% dos casos de líquen plano, as lesões se distribuem ao longo das linhas de Blaschko, variante denominada de líquen plano linear. Relata-se o caso de uma paciente de dois anos e oito meses de idade apresentando pápulas violáceas de superfície ceratósica acomentendo a região abdominal, região glútea e coxa direita, distribuídas ao longo das linhas de Blaschko, cujo exame histopatológico confirmou o diagnóstico de líquen plano linear.

Lichen planus is an uncommon disease in children, and only 2 to 3% of affected patients are under twenty years of age. This dermatosis may appear in several clinical forms, which vary according to the morphology and distribution of lesions. In less than 0.2% of all lichen planus cases, the lesions are distributed along the lines of Blaschko, and is a variant called linear lichen planus. This is a case report of a patient aged two years and eight months, who presented keratotic violaceous papules, affecting the abdomen, buttocks and right thigh, distributed along the lines of Blaschko. Histopathological examination confirmed a diagnosis of linear lichen planus.

The in vitro leishmanicidal activity of miltefosine® (Zentaris GmbH) was assessed against four medically relevant Leishmania species of Brazil: Leishmania (Leishmania) amazonensis, Leishmania (Viannia) braziliensis, Leishmania (Viannia) guyanensis and Leishmania (Leishmania) chagasi. The activity of miltefosine against these New World species was compared to its activity against the Old World strain, Leishmania (Leishmania) donovani, which is known to be sensitive to the effects of miltefosine. The IC50 and IC90 results suggested the New World species harboured similar in vitro susceptibilities to miltefosine; however, miltefosine was approximately 20 times more active against the Old World L. (L.) donovani than against the New World L. (L.) chagasi species. The selectivity index varied from 17.2-28.9 for the New World Leishmania species and up to 420.0 for L. (L.) donovani. The differences in susceptibility to miltefosine suggest that future clinical trials with this drug should include a laboratory pre-evaluation and a dose-defining step.

The leishmanicidal activity of four batches of meglumine antimoniate, produced in Farmanguinhos-Fiocruz, Brazil (TAMs), was assessed and compared to Glucantime®-Aventis Pharma Ltda. Using the amastigote-like in vitro model, the active concentrations of Sb v varied from 10µg/ml to 300 µg/ml for L. (L.) chagasi and from 50µg/ml to 300µg/ml for L. (L.) amazonensis, with no statistically significant differences among the four batches of TAMs and Glucantime®. The inhibitory concentrations (IC50) determined by the amastigote-infected macrophage model for TAM01/03 and Glucantime® were, respectively: 26.3µg/ml and 127.6µg/ml for L. chagasi, 15.4µg /ml and 22.9µg/ml for L. amazonensis, and 12.1µg/ml and 24.2µg/ml for L. (V.) braziliensis. The activities of the four batches of TAMs were confirmed in an in vivo model by assessing, during eight weeks skin lesions caused by L. braziliensis in hamster that were treated with 20mg Sb v/Kg/day for 30 consecutive days. The meglumine antimoniate produced by Farmanguinhos was as effective as the reference drug, Glucantime®-Aventis, against three species of Leishmania that are of medical importance in Brazil.
