Objective: To access how individuals with and without bipolar disorder differ in the use of Facebook, using the Mood Disorder Questionnaire (MDQ) as a screening instrument for Bipolar Disorder (BD). The bipolar spectrum group will be analyzed in another paper. Method: One questionnaire containing 54 questions about social and demographic variables, aspects of Facebook usage and the MDQ was applied. The sample consisted of 672 Facebook users. Participants were classified into three groups: 1-individuals with BD (n=73); 2-individuals without BD (n=402); 3-bipolar spectrum (subjects whose scores were not enough to fulfill the complete criteria for BD) (n=197). Data analysis was performed using the chi-square test (χ²) among the three groups. When this result was statistically significant, pairwise comparisons were performed using ANOVA (with Sheffé correction) tests. Bonferroni test was used to reduce type I error of multiple comparisons. This paper present differences between individuals with without BD. Results: Individuals with BD presented higher percentage than individuals without BD in the following aspects related to the use of Facebook: a) the amount of friends (more than 1,000 friends: 1=20.5%; 2=10.0%); b) the number of people excluded (excluded more than 30 friends: 1=24.7%; 2=14.4%) or blocked from their contacts (blocked more than 30: 1=5.5%; 2=1.7%); c) increased privacy exposure online (excessive exposure on the internet: 1=6.8%; 2=3.2%); d) problems in private life (1=52.1%; 2=19.4%); e) influences of emotional status on online behavior (1=65.8%; 2=41.5%); f) use when worried/anxious (1=49.3%; 2=29,4%). Conclusions: Individuals with BD are more sensitive, excluding and blocking more frequently and use the internet more often when they are more emotional.
Objetivos: Relatar o caso de um adolescente que apresenta, simultaneamente e na mesma topografia, lesões de vitiligo e alopecia areata, sem lesões em outras áreas. Metodologia: Relato de caso elaborado a partir de anamnese, exame físico e exame histopatológico, complementado por revisão da literatura, respeitando todos os aspectos éticos exigidos pelo Comitê de Ética em Pesquisa e com aprovação do mesmo (parecer número 4.279.302). Resultados: Paciente do sexo masculino, 13 anos, iniciou aos 12 anos quadro de alopecia no couro cabeludo sobre áreas de acromia. O paciente não apresentava comorbidades e não foram evidenciadas lesões semelhantes em outras regiões do corpo. Conclusão: Vitiligo e alopecia areata são doenças de etiologia autoimune, cuja associação é bem conhecida. Há, porém, poucos casos descritos da ocorrência simultânea de lesões dessas doenças na mesma área anatômica.
Objetivo: relatar o caso de uma paciente, sexo feminino, apresentando lesões clinicamente e histopatologicamente compatíveis com acne agminata, localizadas na face e nas axilas bilateralmente, e sua evolução com a terapia com doxiciclina. Metodologia: foram utilizados como ferramentas de pesquisa o PubMed e Scielo para revisão bibliográfica, definição terapêutica e escrita deste relato. Realizado biópsia cutânea incisional para comprovação diagnóstica. Como tratamento, foi prescrito doxiciclina em monoterapia, com dose inicial de 200mg/dia durante o primeiro mês, seguido de 100 mg/dia por 3 meses. Foram realizadas reavaliações mensais, com documentações fotográficas. Resultados: após 30 dias de terapia, houve melhora do eritema, do prurido e da infiltração nas lesões. Após 120 dias, havia poucas lesões em atividade, sendo a maior parte residual. Conclusão: a acne agminata ou lupus miliaris disseminatus faciei é uma doença cutânea inflamatória granulomatosa de etiologia rara e incerta, de caráter benigno e autolimitado, com duração media de 18 meses. São descritos várias modalidades terapêuticas, com resultados controversos na literatura. A paciente do relato teve boa resposta a doxiciclina, evitando as sequelas cicatriciais puntiformes e inestéticas.
Introduction: The knowledge of the relationship between Visceral Leishmaniosis and climatic aspects is already well established in the literature of other countries, but lack data of this relationship in Brazil. Objective: This study aimed to describe the seasonal distribution of hospitalizations for Visceral Leishmaniosis (VL) in a referral hospital for infectious diseases located in an endemic area of the semiarid in the Northeast of Brazil. Methods: The number of monthly hospitalizations between 2003 and 2012 was recorded retrospectively and was correlated with climate variables. Results: During this period 1,302 patients were hospitalized. We observed an inverse relationship with the monthly amount of precipitation (r = - 0.725; p = 0.008), the number of days per month with precipitation (r = - 0.683; p = 0.0144) and relative humidity (r = - 0.746; p = 0.005) when compared with the monthly number of hospitalizations due to VL. Inversely, there was a direct relationship with the maximum monthly mean temperature and the number of hospitalizations due to VL (r = 0.643; p = 0.024). Conclusions: The rainy season, characterized by more rainfall and higher humidity, was correlated with fewer hospitalizations for VL. Conversely, in months with higher temperatures the number of hospitalizations for VL was higher.
