RESUMEN
Different studies showed fat intake in childhood and adolescence has long term effects on health, increasing the risk of non communicable disease in adulthood. In Iran the prevalence of cardiovascular risk factors is increasing, while the age of incidence has decreased. The aim of this study is evaluate the prevalence of dyslipidemia in adolescents, aged 10-19 years, in Ahvaz. This descriptive analytic cross sectional study was conducted in the Ahvaz health center, using multistage cluster sampling. After giving complete information to participants about the research, written informed consent was obtained from each participant or their parents and questionnaires were completed for all participants. Blood sampleing, and demographic information including waist, height and weight were measured by standard methods. In this study, 2239 adolecents, aged 10-19 years were enrolled; 1117[49.9%] boys and 1122[50.1%] girls. The prevalence of hyperlipidemia according to AAP was 29.9% [boys 32.8%, 27.1% girls]. Compared to boys, mean total cholesterol and LDL were higher in girls, aged between 10-14 years. Lipid factors were more prevalent in 14-15 year old girls and in 16-17 year old boys. Prevalence of hyperlipidemia increased with increase in BMI. Dyslipidemia has a significant prevalence among adolescents in Ahvaz, necessitating special attention be paid to educating people on diet and exercise to prevalence condition
RESUMEN
Although some studies show that Chromium picolinate supplementation can improve glycemic control in type 2, diabetic patients, information available in this regard is conflicting. The aim of this study is to determine the effect of chromium picolinate on glycemic control in subjects with type 2 diabetes. In this the randomized, double blind placebo controlled clinical trial, 40 patients with type 2 diabetes were investigated. They were divided into two groups [n=20 each], the randomized and placebo groups, the former receiving 200 microgram chromium as chromium picolinate [n=20] for 3 months. Body composition, lipid profile, and glycemic control were determined at baseline and at the end of study. Subjects randomized to chromium picolinate, as compared to the placebo group, had a significant decrease in HbA[1C] [-41%, P=0.007vs. 0.12%, P = 0.054] and FBS levels [-22.05%, P = .001 vs. -1.35%, P= .859]. There was no improvement in body composition and lipid profiles of subjects randomized to chromium picolinate, compared to controls. Results of this study suggest that chromium picolinate supplementation in subjects with type 2 diabetes can improve glucose control but it has no effect on body composition and lipid profiles.
RESUMEN
Osteoporosis is a major health problem for postmenopatisal women and use of dual x-ray absorptiometry [DXA] is standard diagnostic method. But due to the cost, it is not economical to use for screening of all postmenopausal women, thus, the aim of this study was to evaluate performance of Osteoporosis Risk Assessment Instrument [ORAI] as a tool for screening of Osteoporosis among Iranian postmenopausal women. In this study data was collected from a bone densitometry centre. The Osteoporosis risk was evaluated for 341 postmenopausal women [age > 45 years] without consider secondary cause of Osteoporosis. The results were compared with their bone mineral density. From 341 postmenopausal women, 20.8% were showed osteoporotic and 39.6% had low bone mineral density in one or both studied area by DXA. To assess Osteoporosis of low bone mass, ORAI was shown a sensitivity of 70.9% and specificity of 66.9% respectively. The ORAI was adequate sensitivity to evaluate Iranian postmenopausal women. This test could be used as screen test to determinate low bone mineral density to referral of women
RESUMEN
Brown tumor or Osteitis Fibrosa Cystica [OFC] is a rare clinical entity complicating hyperparathyroidism. It may occur in the head and neck, with the mandible being the most frequent site. Primary hyperparathyroidism is usually associated with hypercalcemia. We report a 35 years old female with mandibular brown tumor secondary to primary hyperparathyroidism. In this case in spite of primary hyperparathyroidism and the bony lesion the serum calcium level was within normal limit. This case demonstrates that in osteolytic bony lesions a hyperparathyroidism complication can be expected even with normal serum calcium level. The presence of normocalcemia in hyperparathyroidism should prompt the physician to measurement of ionized calcium and look for vitamin D deficiency, magnesium deficiency, impaired renal function, use of interacting drugs and associated disorders. If there weren't these factors, normocalcemic primary hyperparathyroidism should be considered
