We present a unique case of a 62-year-old patient with bilateral osteonecrosis of the femoral heads secondary to corticosteroid use. She presented with an occult right femoral neck fracture and was treated with percutaneous pinning of the right femoral neck and a left-sided percutaneous drilling. Despite apparent appropriate technique, the patient sustained a left sub-trochanteric hip fracture while shifting in bed in the postoperative care unit and was taken back for cephalo-medullary nail fixation. Femoral head osteonecrosis may be an under-reported risk factor for development of pathological neck fractures...

Introduction: The bisphosphonate-related osteonecrosis of the jaw was first referred to in 2003. Bisphosphonates action is focused on the osteoclasts. The drastic inhibition of the osteoclastic function is harmful for the jaws which are the only bones of the human skeleton in relative contact with the external environment. The adverse effects of the bisphosphonate-related therapy include the pathology for which they are prescribed, the atypical fractures in pathological bone. Method: The aim of this research was to analyze the risk factors and the treatment methods in case of osteonecrosis of the jaws...

Necrotizing autoimmune myopathy is characterized by predominant muscle fiber necrosis and regeneration with little or no inflammation. We describe a 58-year-old woman with previous breast cancer and statin use who complained of rapidly progressive weakness of lower limbs without pain, making walking, running and climbing stairs difficult. The creatine kinase level was 2,843 U/L, and muscle biopsy showed a dystrophic pattern. The genetic test for muscular dystrophies was negative and for anti-3-hydroxy-3-methylglutaryl coenzyme A reductase was positive...

BACKGROUND: Vitamin D (vitD) deficiency is prevalent among childhood hematopoietic stem cell transplantation (HSCT) recipients and associated with inferior transplant survival at 100 days after transplantation. Achieving and maintaining therapeutic vitD levels in HSCT recipients is extremely challenging in the first 3-6 months after transplant due to poor compliance in the setting of mucositis, and concomitant use of critical transplant drugs that interfere with vitD absorption. We sought to evaluate the safety and efficacy of a single, ultra-high dose of vitD given prior to childhood HSCT to maintain levels in a therapeutic range during the peri-transplantation period...

Bone is a complex endocrine organ that facilitates structural support, protection to vital organs, sites for hematopoiesis, and calcium homeostasis. The bone marrow microenvironment is a heterogeneous niche consisting of multipotent musculoskeletal and hematopoietic progenitors and their derivative terminal cell types. Amongst these progenitors, bone marrow mesenchymal stem/stromal cells (BMSCs) may differentiate into osteogenic, adipogenic, myogenic, and chondrogenic lineages to support musculoskeletal development as well as tissue homeostasis, regeneration and repair during adulthood...

Calciprotein particles (CPPs) are a new biological marker of chronic kidney disease-mineral and bone disorder (CKD-MBD). CPPs consist of phosphate, calcium, and some proteins, with phosphate being the major contributor to the level and biological activity of CPPs. Recent studies have shown the physiological and pathological significance of CPPs, including contributions to bone and mineral metabolism, and to tissue and organ impairments such as cardiovascular damage and inflammatory responses. These actions are well known as important aspects of CKD-MBD...

There is not enough evidence in the literature to support the use of any classification system for distal radius fractures (DRF) in adults. However, there is a need for identification of more homogeneous groups of patients with DRF so that the extent of preoperative workup and sophistication of treatment would best match the needs of the patient. The authors propose an innovative method to analyse and stratify acute DRF in adults. A one-page chart includes criteria related to the patient (P), the energy of the accident (A) and the pathology of the fracture (F)...

Multiple myeloma is the second most frequent hematological malignancy in the western world and remains incurable, predominantly due to acquired drug resistance and disease relapse. The highly conserved Wnt signal transduction pathway, which plays a key role in regulating cellular processes of proliferation, differentiation, migration, and stem cell self-renewal, is associated with multiple aspects of disease. Bone homeostasis is severely disturbed by Wnt antagonists that are secreted by the malignant plasma cells in the bone marrow...

INTRODUCTION: Bone defect reconstruction in orbital wall fractures with absorbable alloplastic such as the unsintered hydroxyapatite and poly L-lactide composite (u-HA/PLLA) system is gaining popularity. The u-HA/PLLA material has osteoconductive and osteosynthetic properties. However, quantitative, long-term outcome data after the use of u-HA/PLLA for orbital wall fractures are lacking. PATIENTS AND METHODS: We retrospectively analyzed 115 patients who underwent surgical repair of orbital wall fractures with a u-HA/PLLA sheet from 2011 to 2016...

Background and study aims  Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is widely performed to obtain pathological evidence from several parts of the body. Major complications of EUS-FNA are bleeding, pancreatitis, and abdominal pain. Needle fracture is a rare complication of EUS-FNA and only a few relevant reports are available. Here, we report a case of needle fracture during EUS-FNA using a needle with a side hole. A 61-year-old man underwent EUS-FNA of the uncinate process of the pancreas to confirm malignancy...
