A anemia ferropriva possui diversas etiologias, como nutricional, absortivas, metabólicas ou distributivas, sangramento e aumento das necessidades fisiológicas. Apesar do impacto epidemiológico e clínico, a anemia ainda permanece incerta quanto à epidemiologia, principalmente pela falta de dados consistentes em nossa região. O objetivo deste estudo foi determinar o perfil epidemiológico dos pacientes atendidos pelo serviço de hematologia de um hospital público do estado de São Paulo no período de 2005 a 2010, com diagnóstico de anemia ferropriva. Trata-se de um estudo transversal que utilizou o prontuário dos pacientes, sendo avaliados: sexo, idade, exames laboratoriais e etiologia. A associação entre faixa etária, grupo populacional e sexo com as origens etiológicas da anemia ferropriva foi estudada com o teste de Qui-quadrado de Pearson e as estimativas das razões de chances (Odds-ratio) por ponto e por intervalos com 95% de confiança. Foram incluídos 188 pacientes com diagnóstico de anemia ferropriva. Destes, 128 (68%) eram do sexo feminino e 60 (32%) do sexo masculino, a média etária geral foi de 52 anos e as etiologias mais prevalentes foram: perda sanguínea por via urogenital 71 (37,70%), gastrointestinal alta (34,57%) e baixa (23,94%). O perfil dos pacientes com anemia ferropriva que procuraram o serviço de hematologia, mostrou que a menorragia constitui a principal etiologia para mulheres em idade reprodutiva, representando cerca de 1/3 dos casos. As perdas gastrointestinais alta e baixa, representam mais da metade dos casos e o risco de chances, para ambas é maior para homens e idosos independente do sexo.

Introduction: The inclusion of new methodologies and assessments in the medical education area has indicated the need to understand teachers’ perception of their own ability to use them adequately. Objective: Thus, the present study aimed to investigate possible associations between teacher self-efficacy and the use of OSCE. Method: The Teacher Self-efficacy Scale and Self-Efficacy Sources Scale and a characterization questionnaire were used. Forty-seven medical teachers from a private university, of both genders, aged between 31 and 78 years, participated in the study. Results: The results indicated that the factors Social Persuasion and Vicarious Learning were the most endorsed, suggesting that these sources are the ones that interfere the most in the formation of the participants’ beliefs. There was only one positive and statistically significant correlation, with a weak magnitude, established between the Intentionality of Action Efficacy and Vicarious Learning. The other identified correlations were statistically negative and of moderate magnitude. Conclusions: The teachers who agreed with some important characteristics about the OSCE method also showed higher levels of self-efficacy. Therefore, professionals with greater perseverance, resilience and confidence, have also been more committed to teaching, research and student assistance.

Agranulocytosis is characterized by a reduction of neutrophils in peripheral blood, and about two thirds of cases occur due to adverse reactions to drugs. We report a case of a Caucasian man that in prolonged use of oxacillin due a septic spondylodiscytis developed agranulocytosis. Male patient, 70 years-old, was admitted to the emergency room complaining of pain in the lumbar region for 30 days. Diagnosed with septic spondylodiscytis on plateaus vertebral level L5-S1. He was treated empirically with oxacillin. Antibiotic therapy continued until the twenty-ninth day. Blood count presented: leukocyte counts of 0.870/mm³ (without differential count). After suspension of oxacillin, white blood cell count was not reestablished, was administered granulocyte colony-stimulating factor Filgastrima at a dose of 0.5MU/Kg day (5g/Kg/day) for three days. This report aims to highlight that the use of intravenous oxacillin for prolonged periods may induce agranulocytosis, and to emphasize that even asymptomatic patient monitoring should be performed.
