The aim of our study was to prospectively evaluate bone density in adolescents females with JIA, and to correlate the results with puberty. Lumbar spine (L2–L4) areal bone mineral density (aBMD) (assessed by Dual X-ray Absorbiometry, DXA) was monitored every 6–12 months in a group of 38 girls with JIA. The evaluated bone density accrual during the peripubertal time as well as absolute and relat...

ObjectiveTo evaluate bone mineral mass in adolescents with failure to thrive in relation to body composition.MethodsA case control study involving 126 adolescents (15 to 19 years), in final puberty maturation being 76 eutrophic and 50 with failure to thrive (genetic or constitutional delay of growth), of matching ages, gender and pubertal maturation. The weight, height and calculated Z score fo...

The regulation of bone metabolism mediated by leptin is a complex process that is not clearly understood. Recent studies suggest that CART (cocaine-amphetamine related transcript) is a significant neuronal co-factor when combined with leptin. CART deficiency is thought to result in low trabecular bone mass, but since leptin exerts contrasting effects on trabecular and cortical bone it is possib...

Context: The hormonal factors involved in the regulation of peak bone mass in men have not been fully investigated. Aside from gonadal steroids and somatotropic hormones, thyroid hormones are known to affect bone maturation and homeostasis, and are additional candidate determinants of adult bone mass. Objective: We aimed to investigate between-subject physiological variation in free and total t...

adenocarcinoma of the stomach was the leading cause of cancer-related death worldwide through most of the 20th century. usual presentations of gastric cancer include anorexia, epigastric pain or discomfort and weakness. rarely, patients present with unusual clinical manifestations. in this article, we report two cases with uncommon presentations of gastric adenocarcinoma. the first patient was ...

We investigated several factors which affect the stability of cortical screws in osteoporotic bone using 18 femora from cadavers of women aged between 45 and 96 years (mean 76). We performed bone densitometry to measure the bone mineral density of the cortical and cancellous bone of the shaft and head of the femur, respectively. The thickness and overall bone mass of the cortical layer of the s...

Fracturing after liver transplantation (OLT) occurs due to the combination of preexisting low bone mineral density (BMD) and early posttransplant bone loss, the risk factors for which are poorly defined. The prevalence and predictive factors for hepatic osteopenia and osteoporosis, posttransplant bone loss, and subsequent bone gain were studied by the long-term posttransplant follow-up of 360 c...
