Background: This study was designed to investigate the process of bone formation caused by implantation of octacalcium phosphate (OCP) in rat tibiae.Methods: We used 25 young male Sprague–Dawley rats. A full thickness standardized trephine defect, 3-mm in diameter, was surgically created on the superior end of right and left tibia. Amount of 6-μg synthetic octacalcium phosphate was implanted into a bony defect on the right tibia as an experimen...

The aim of the research was to determine the efficacy of alfacalcidol (Alpha D3 Teva) in the treatment of women with postmenopausal osteoporosis and vitamin D deficiency.Methods: 20 women with systemic postmenopausal osteoporosis were examined. All patients had vitamin D deficiency (the average level of 25(OH)D in blood serum was (37.16 (24.9, 45.1)) nmol/l). Alfacalcidol was prescribed for 12 month in doses 1 μg. duration of observation was 12 mont...

Background: High doses of zoledronic acid (ZOL), one of the most potent inhibitors of bone resorption; is currently evaluated in a phase III clinical trial in Europe for the treatment of malignant pediatric primary bone tumors. The impact of such an intensive treatment on the craniofacial skeleton is a critical question in the context of patients with actively growing skeleton; in particular in the light of our previous studies evidencing that endochondral bone formation was t...

Receptor activator of nuclear factor kappa B ligand (RANKL)-induced activation of NF-κB and MAPKs signaling pathways is critical to osteoclastogenesis. Glossogyne tenuifolia has been used as an antipyretic, detoxication, and anti-inflammatory herb tea in Penghu Island, Taiwan. This study investigated the effects of G. tenuifolia ethanolic extract (GTE) on the formation of RANKL-activating osteoclasts and expression of signaling pathways using a RAW264.7 ...

Objective: To assess the prevalence of post-operative medical and surgical complications among fracture neck of femur patients.Method: Study design: retrospective cohort study.Setting: District General Hospital in UK.Study subject: a total of 75 patients with fracture neck of femur from 2012 to 2013 were ascertained for any post-operative complications by case note study.Results: Out of...

Alendronate is one of the most popular anti-resorptive drugs and widely used to treat osteoporotic patients in the world. In Japan, alendronate oral jelly (ALN-J) as a new formulation was launched in 2013. Dissolution test and bioequivalence study were performed between ALN-J and alendronate oral weekly tablet (ALN-T), and bioequivalence of both drugs was approved. Dosage and administration of ALN-J is the same as ALN-T. Moreover, ALN-J has special features of easy swallowing ...

Long-term bisphosphonate (BP) therapy can be complicated by atypical femoral fracture (AFF). A positive effect of teriparatide (TPTD) has been suggested.A woman (A, 81) with densitometric OP was put on alendronate (ALN) from 1997 until 2006, substituted by ibandronate (IBA), with an increase in FN-BMD of 6.6%. In August 2010, a fall from her standing height provoked a right transverse femoral fracture, which was operated. She was weaned from BP therapy. ...

: Rickets can occur due to vitamin D deficiency or defects in its metabolism. Mutations in the CYP27B1 gene, which encodes vitamin D 1α-hydroxylase, are the genetic basis of vitamin D-dependent rickets type 1A (VDDR1A, OMIM 264700). Vitamin D dependent rickets type 1 is inherited in an autosomal recessive pattern. We report here a new mutation in CYP27B1, which lead to vitamin D dependent rickets type 1. Two boy siblings from a consanguineous Turkish family presented to e...

Background: Calcinosis cutis, the deposition of insoluble calcium salts in the cutaneous and subcutaneous tissue, is rare during infancy. Calcifications are most frequently reported after subcutaneous fat necrosis, hypothermia in neonates or following extravasation of calcium gluconate.Presenting problem: The patient was born at term by caesarean section because of fetal distress; the birth weight was 2426 g. At age 4 weeks, he was admitted to the hospit...
