Objectives: This cross-sectional study was done in order to assess the prevalence and determinants of vitamin D deficiency in children taking in account the following parameters: children’s age, season, geographic region and ethnicity.Methods: A cross-sectional prospective study was conducted in Israeli children aged 0–18 from Meuhedet Health Services during the year of 2016 in primary care pediatric clinics throughout all different geographic ...

Methimazol is an antithyroid drug for treatment of hyperthyroidism. Methimazol inhibits the enzyme thyroperoxidase participating in thyroid hormone synthesis and reduces triiodothyronine (T3) and thyroxine (T4) blood concentrations. The study was performed to determine effects of 90-day long oral administration with methimazol on femur properties isolated from male Wistar rats. The first group (n=6) consisted of control rats. The experimental rat...

There is increasing evidence for the key role of osteocytes in the regulation of bone remodeling. One of the main products of these cells, sclerostin, inhibits bone formation and may also stimulate bone resorption. To our knowledge, there are few data in prostate cancer (PC) patients especially in patients with hypogonadism related to androgen deprivation therapy (ADT). The aim of this study was to compare serum levels of sclerostin in ADT-treated and untreated PC patients wit...

Introduction: The utility of the determination of bone turnover markers in the evaluation of fracture risk at the patient level is not well-established. In type 2 diabetes (T2DM) there is an increased risk of fractures despite of higher bone mineral density. A recent study shows that a femoral neck T-score of −2.1 in males and −1.9 in females with T2DM present the same fracture risk than subjects without diabetes with a T-score −2.5 (Schwart...

FGFR3 activating mutations are responsible for achondroplasia (ACH), the most common form of dwarfism. ACH clinical features include short stature, midface hypoplasia, frontal bossing and prognathism and both endochondral and membranous ossifications are disturbed. It is unknown if abnormal mandibles are present in ACH. To date, it is believed that primary (Meckel’s) and secondary (angular and condylar) cartilages play important roles in determining the final shape and po...

Recent studies have demonstrated the role of osteocalcin in energy metabolism regulation having a connection between this and bone metabolism. According to this, anti-osteoporotic drugs may exert different effects on energy metabolism. Thereby, our aim is to evaluate the effects of antiresorptive (Denosumab) and osteoanabolic (Teriparatide) drugs that reduce or increase respectively osteocalcin levels, on energy and bone metabolism by assessing of undercarboxilated osteocalcin...

Objectives: Vitamin D deficiency is of current interest especially in high risk patients for reduced bone mineral density as in pediatric hematologic oncologic patients.Methods: During a 4 year period 194 pediatric hematologic oncologic patients were screened for serological vitamin D deficiency (defined as 25 (OH)D levels <30 ng/ml and accordingly <75 nmol/l). 61 patients were in the prospective group 1 defined as screening at time of diagnosis,...
