A 32-year-old woman presented with progressive myalgia, bone pain, fatigue, insufficiency hip fractures, high urine phosphate, and low serum phosphate and vitamin D levels. These findings were suggestive of oncogenic osteomalacia. A whole-body Tc-octreotide scintigraphy with SPECT/CT showed uptake on a sclerotic intramedullary lesion in the left medial tibia plateau. MRI depicted a solid lesion. The lesion was surgically removed; the patient became asymptomatic, and follow-up laboratory results normalized. Histopathologic examination revealed a vascular hemangiopericytoma-like tumor, positive for somatostatin receptor (SSR-2). Whole-body Tc-octreotide scintigraphy with SPECT/CT may detect occult oncogenic osteomalacia tumors.

A 43-year-old man, previously submitted to right hepatectomy, right hepatic artery chemoembolization, and surgical resection of liver lesions, with well-differentiated and moderately differentiated hepatocellular carcinoma (HCC) confirmed by histopathology, underwent cholescintigraphy with Tc diisopropyliminodiacetic acid (Tc-DISIDA) due to recurrent cholangitis. The scintigraphic images and the coregistered CT images showed radiotracer uptake in an area of biliary ectasia near the hepatic surface (which may be associated with recurrent cholangitis), in a hepatic nodule, and in multiple pulmonary metastases.

CONTEXTO E OBJETIVO: A anemia ferropriva é um importante problema de saúde pública no Brasil. No município de Embu, estudo populacional realizado em 1996 verificou prevalência de anemia de 68,5% em crianças de um a dois anos. A partir desses resultados, o uso de sulfato ferroso profilático foi introduzido em 1998 no Programa de Saúde da Criança para as crianças a partir do desmame até os dois anos de idade. Após cinco anos de intervenção, avaliou-se a prevalência de anemia e os fatores associados, em crianças de 12 a 18 meses de idade que receberam orientação para uso profilático de sulfato ferroso. TIPO DE ESTUDO E LOCAL: Estudo transversal analítico realizado no período de 10/2003 a 06/2004 em Unidade Básica de Saúde, Embu. MÉTODO: Amostra aleatória de crianças entre 12 a 18 meses que receberam orientação do uso de ferro profilático. Mensuração de hemoglobina em sangue capilar através do aparelho portátil HemoCue®. Hemoglobina < 11 g/100 dl foi considerada anemia. RESULTADOS: A amostra foi composta por 118 crianças. A prevalência de anemia foi de 41,5%. Não foi observada associação estatisticamente significativa entre a anemia e as variáveis: sexo, peso ao nascer, intercorrências neonatais, doenças crônicas, internação anterior, aleitamento materno, uso de suplementação de ferro, estado nutricional. Verificou-se associação estatisticamente significante (p = 0,03) entre a presença de anemia e renda per capita, em que a maior renda associou-se a menor prevalência de anemia. CONCLUSÃO: O programa de profilaxia da anemia ferropriva não alcançou os resultados esperados. Novas estratégias devem ser consideradas frente à magnitude do problema. CONTEXT AND OBJECTIVE: Iron deficiency anemia is an important public health problem in Brazil. In the municipality of Embu, a population study in 1996 found anemia prevalence of 68.5% among children aged one to two years. From these data, prescription of prophylactic ferrous sulfate was instituted in 1998 for children under two years old followed up within the children's healthcare program. After five years of intervention, the prevalence of anemia and associated factors were investigated among children aged 12 to 18 months to whom guidance for prophylactic ferrous sulfate use had been given. DESIGN AND SETTING: Cross-sectional study covering October 2003 to June 2004 at a primary healthcare unit in Embu. METHODS: A randomized sample of children aged 12 to 18 months to whom guidance for prophylactic ferrous sulfate use had been given was obtained. Hemoglobin was measured in capillary blood, using HemoCue® apparatus. Hemoglobin < 11 g/100 dl was taken to indicate anemia. RESULTS: The sample comprised 118 children and anemia was found in 41.5%. There was no statistically significant association between anemia presence and the variables of sex, birth weight, neonatal intercurrences, chronic diseases, breastfeeding or iron supplementation use. There was a statistically significant association (p = 0.03) between anemia presence and per capita income, such that the higher the income was, the lower the prevalence of anemia was. CONCLUSION: The prophylaxis program against iron deficiency anemia did not achieve the expected results. New strategies must be considered in the light of the magnitude of the problem.
