RESUMOSelecionamos mulheres pré-menopausadas com redução da DMO encaminhadas ao ambulatório de Metabolismo Ósseo do Hospital de Clínicas da UFPR, com o objetivo de definirmos o perfil destas pacientes em relação aos fatores de risco e prováveis causas secundárias de osteoporose. Trinta e quatro mulheres foram estudadas (19-48 anos). Em 29 pacientes (85,3%) a coluna lombar estava acometida, 8 (23,5%) apresentaram Z-score < -2,5 e 21 (61,8%) Z-score entre -1,0 e -2,5. Vinte pacientes (58,8%) apresentaram redução da DMO em fêmur, 2 (6,2%) com Z-score < -2,5 e 18 (56,2%) com Z-score entre -1,0 e -2,5. Causa secundária foi identificada em 26 pacientes (76,5%). Este estudo demonstra que a realização de densitometria óssea é importante em mulheres na pré-menopausa com fatores de risco para redução da massa óssea, uma vez que permite o início precoce do tratamento e a prevenção das complicações relacionadas. ABSTRACT Main Causes of Low Bone Mass in Premenopausal Women Referred to a Metabolic Bone Clinic of Curitiba.We conducted a chart review of premenopausal women with low bone mineral density referred to the Metabolic Bone Clinic of Federal University of Paraná, to determine the outline of these patients regarding their risk factors and secondary causes of osteoporosis. Thirty-four women (19-48 years old) were evaluated. Twenty nine (85.3%) patients presented a low bone mineral density (BMD) in lumbar spine, 8 (23.5%) had Zscore < -2.5 and 21 (61.8%) had Z-score between -1.0 and -2.5. Twenty patients (58.8%) had a low bone mass in total femur, 2 (6.2%) with Z-score < -2.5 and 18 (56.2%) with Z-score between -1.0 and -2.5. A secondary cause could be identified in 26 patients (76.5%). This study shows that DMO is important in premenopausal women with risk factors of low BMD because it leads to the best treatment option and follow-up.

Objective: The objective of this study was to determine the prevalence of celiac disease (CD) in adults with autoimmune thyroid disease (ATD) from the endocrinology outpatient setting in a university hospital in Southern Brazil. Subjects and methods: From the years 2007 to 2011, 254 patients with ATD were enrolled consecutively, Grave's disease was diagnosed in 143 (56.3%) and Hashimoto's thyroiditis in 111 (43.7%) of them. All patients answered a questionnaire related to symptoms that could be associated with CD and serum samples to screen for IgA anti-endomysial (EmA-IgA) were collected. EmA-IgA-positive patients were offered upper gastrointestinal endoscopy and biopsy of duodenum. Results: A total of 254 patients were included; 222 (87.4%) female, mean age 45.4 ± 13.43 years (18 to 79 years). EmA-IgA was positive in seven patients (2.7%) and five done endoscopy with biopsy. Of these, three diagnosis of CD was confirmed (1.2%). All the three patients with CD had higher EmA-IgA titration, were female and had Hashimoto's thyroiditis. Like other patients with ATD, CD patients had nonspecific gastrointestinal symptoms, such as heartburn and gastric distention. In our study, one in each 85 patients confirmed the diagnosis of CD. Conclusion: We found a prevalence of 1.2% (1:85) of confirmed CD among Brazilian patients with ATD. Although some IgA-EmA positive patients had Graves' disease and one was male, all three patients with confirmed CD were female and had Hashimoto's thyroiditis.

The intravenous pamidronate in a group of postmenopausal women with predominant high risk of fracture promoted an isolated gain in the spine BMD, even though, clinical randomized trials are needed to confirm its anti-fracture efficacy.
