Comparative Effect of rhPTH(1-84) on Bone Mineral Density and Trabecular Bone Score in Hypoparathyroidism and Postmenopausal Osteoporosis.

Parathyroid hormone (PTH) (1-84) improves lumbar spine (LS) areal bone mineral density (aBMD) and trabecular bone score (TBS) in hypoparathyroidism over a 2-year treatment period. Studies in osteoporosis have shown that with PTH(1-34) there is a significant increase in LS aBMD and TBS. In this article, we provide new data comparing the effects of the same form of PTH, namely recombinant human PTH, rhPTH(1-84), on aBMD and TBS in hypoparathyroid and osteoporotic patients over an 18-month treatment period.

Algorithmic treatment of Busch-Hoffa distal femur fractures: A technical note based on a modified Letenneur classification.

Treatment of distal femur fractures in the coronal plane can be challenging. Depending on fracture line orientation, topography and associated comminution, decision-making regarding approach and fixation is not straightforward and can result in complications. Therefore, treatment of coronal plane distal femur fractures (Busch-Hoffa fractures) should be approached in a systematic manner, leading to efficient planning and operative execution.

Subtrochanteric and Distal Femur Fractures in a Patient with Femoral Shaft Fracture Malunion and Knee Disarticulation: A Rare and Challenging Case Report.

This study aims to describe a rare and challenging case of a patient who presented ipsilateral subtrochanteric and distal femur fractures due to low-energy trauma. The peculiarity of this case is the presence of femoral shaft fracture malunion and knee disarticulation in the same limb resulting from an accident suffered 30 years ago. The patient underwent femoral diaphyseal osteotomy and fixation of the subtrochanteric and distal femur fractures with a long cephalomedullary nail and distal femur locking plate, respectively.

Ultrastructural deposits appearing as "zebra bodies" in renal biopsy: Fabry disease?- comparative case reports.

Background: Fabry Disease (FD) is a genetic disorder caused by alpha-galactosidase A deficiency. Certain drugs, such as hydroxychloroquine, can produce renal deposits that mimic morphological findings seen in FD, characterizing a type of drug-induced renal phospholipidosis.

Case Presentation: Case 1: A 28-year-old female patient with systemic lupus erythematosus who had been using hydroxychloroquine for 14 months presented subnephrotic proteinuria.

Validation of a new classification system for interprosthetic femoral fractures.

Interprosthetic femoral fracture (IFF) incidence is gradually increasing as the population is progressively ageing. However, treatment remains challenging due to several contributing factors, such as poor bone quality, patient comorbidities, small interprosthetic fragment, and prostheses instability. An effective and specific classification system is essential to optimize treatment management, therefore diminishing complication rates.

Bone imaging in hypoparathyroidism.

Hypoparathyroidism (HypoPT) is an uncommon endocrine disorder characterized by chronic deficiency or absence of parathyroid hormone (PTH), which leads to a profound reduction in bone remodeling. Subjects with HypoPT typically have bone mineral densities (BMDs) by dual-energy X-ray absorptiometry (DXA) above average at all skeletal sites, with greatest scores observed at the lumbar spine. Trabecular bone score (TBS), an indirect measure of bone microarchitecture, also appears to be normal in HypoPT.

Interleukin-1β plasma levels are associated with depression in temporal lobe epilepsy.

Inflammatory mediators such as cytokines are likely to contribute to the pathophysiology of epilepsy. Proinflammatory cytokines are also associated with mood disorders, such as major depression. As people with temporal lobe epilepsy (TLE) are at an increased risk of mood disorders, we attempted to evaluate peripheral levels of IL-1β in people with TLE with depression and people with TLE without depression and in healthy controls.

Fracture Risk Prediction by Non-BMD DXA Measures: the 2015 ISCD Official Positions Part 2: Trabecular Bone Score.

Bone mineral density (BMD) as measured by dual-energy X-ray absorptiometry (DXA) is the gold standard for the diagnosis and management of osteoporosis. However, BMD explains only 60%-80% of bone strength, and a number of skeletal features other than BMD contribute to bone strength and fracture risk. Advanced imaging modalities can assess some of these skeletal features, but compared to standard DXA, these techniques have higher costs and limited accessibility.

Parathyroid hormone: anabolic and catabolic actions on the skeleton.

Parathyroid hormone (PTH) is essential for the maintenance of calcium homeostasis through, in part, its actions to regulate bone remodeling. While PTH stimulates both bone formation and bone resorption, the duration and periodicity of exposure to PTH governs the net effect on bone mass, that is whether it is catabolic or anabolic. PTH receptor signaling in osteoblasts and osteocytes can increase the RANKL/OPG ratio, increasing both osteoclast recruitment and osteoclast activity, and thereby stimulating bone resorption.
