Marcella D Walker, John P Bilezikian
PURPOSE OF REVIEW: The purpose of this review is to describe recent advances and changes in the evaluation and management of primary hyperparathyroidism (PHPT). RECENT FINDINGS: Although it has long been recognized that asymptomatic PHPT is associated with bone loss, particularly at cortical skeletal sites when evaluated with dual-energy X-ray absorptiometry, new imaging techniques suggest that trabecular skeletal deterioration as well as clinically silent vertebral fractures and nephrolithiasis are common...

Inconsistent positioning of patients and region of interest (ROI) is known to influence the precision of bone mineral density (BMD) measurements in the spine and hip. However, it is unknown whether minor shifts in the positioning of the ROI along the shaft of the radius affect the measurement of forearm BMD and its subregions. The ultradistal (UD-), mid-, one-third, and total radius BMDs of 50 consecutive clinical densitometry patients were acquired. At baseline the distal end of the ROI was placed at the tip of the ulnar styloid as usual, and then the forearm was reanalyzed 10 more times, each time shifting the ROI 1 mm proximally...

REVIEW
Laurence Vico, Alan Hargens
Space sojourns are challenging for life. The ability of the human body to adapt to these extreme conditions has been noted since the beginning of human space travel. Skeletal alterations that occur during spaceflight are now better understood owing to tools such as dual-energy X-ray densitometry and high-resolution peripheral quantitative CT, and murine models help researchers to understand cellular and matrix changes that occur in bone and that are difficult to measure in humans. However, questions remain with regard to bone adaptation and osteocyte fate, as well as to interactions of the skeleton with fluid shifts towards the head and with the vascular system...

BACKGROUND: Cytokines are mediators of inflammatory processes in the course of inflammatory bowel disease (IBD) and participate in the bone metabolism. Interleukin 6 (IL-6) initiates osteoclastogenesis by modulating the activity of soluble receptor activator of nuclear factor kappa B ligand (sRANKL) and osteoprotegerin. OBJECTIVES: The aim of the study was to evaluate bone mineral density (BMD) by densitometry and the concentration of interleukin 6, osteoprotegerin (OPG) and sRANKL protein (sRANKL) by ELISA in patients with IBD in relation to the control group; to assess the relationship between IL-6, OPG, sRANKL and BMD; and to assess the impact of disease duration and number hospitalization on BMD...

We report the case of a 50-year-old woman with anorexigen-induced pulmonary arterial hypertension treated with epoprostenol, who presented with Trousseau's sign, leading to the diagnosis of severe hypocalcemia for which substitution was started (initially orally, followed by intravenous substitution). After further analysis, we assume that epoprostenol-induced diarrhea caused malabsorption (as other reasons were excluded), leading to nutritional osteomalacia with secondary hyperparathyroidism. We discovered that even more severe hypocalcemia was induced by the treatment with the anti-osteoporotic drug denosumab, which was started after the diagnosis of osteoporosis on bone densitometry...

Many neuromuscular diseases (NMD) result in muscle weakness, immobility and greater fracture risk. The objective of this study is to determine the fracture risk of adult patients at a multidisciplinary NMD clinic. Fracture risk was calculated using the Fracture Risk Assessment Tool, the presence of osteoporosis was quantified using bone densitometry and contributing co-morbidities were screened through serum markers. Of the 36 patients studied, 47% were found to be of moderate and high fracture risk. Two thirds of these patients had not been previously screened or treated for osteoporosis...

Osteoporosis is a serious medical and socioeconomic problem of the 21st century. Mechanical load is a key regulator which controls bone formation and remodelling, with participation of osteocytes. Sclerostin is produced and released by mature osteocytes into bone surface, where it inhibits the conveyance of osteoblast proliferation and differentiation activating signals from mesenchymal cells, thus suppressing new bone formation. The goal of the study was an evaluation of the effects of a 12-week physical training programme on the levels of bone turnover markers [Sclerostin, Osteocalcin (OC), C-terminal telopeptide of type I collagen (β-CTX)] in blood serum of women with osteopenia...
