Background: Vitamin D has a key physiological role in many metabolic process and neuromuscular activities. The peak bone mass accrual occurred during adolescence, where about 51% of bone mass is gained during puberty and about 37% of the bone mineral density (BMD) of adults is reached. Vitamin D deficiency has long-term negative implications including increased risk of osteomalacia and osteoporosis. Severe hypovitaminosis D appears to be most common in the Mid...

Background: Down syndrome (DS) is the most common genetic (chromosomal) mental retardation syndrome. In these patients, several environmental and hormonal factors contribute to low bone mineral density (BMD), among these factors, vitamin D may play a significant role in the health of patients with DS. However, poor studies have evaluated 25-hydroxy cholecalciferol (25(OH)D) levels in DS.Objective and hypotheses: The purpose of this study was to assess se...

Background: 28 days old baby girl presented to ER with seizure like activity for the last two weeks, breast feeding well and thriving. Past history full term normal delivery, no neonatal complications and no maternal history apart from iron deficiency anemia. Case presentation summary: Examination unremarkable, vitals and sugar were stable intermittent jerky movements of the limbs with no stiffness. Investigations: calcium 7.4 mg/dL, Magnesuim (Mg) 0.52 mg/dL, phosphate 8.3 mg...

Background: Hashimoto thyroiditis (HT) is the most common autoimmune disorder. There are few studies that analysed the relationship between HT and serum vitamin D.Objective and hypotheses: It has been suggested that vitamin D acts as an immunomodulator in autoimmune diseases such as HT Therefore we planned to investigate vitamin D status in euthyroid girls with HT.Method: The study group consisted of 66 euthyroid pubertal girls rec...

Background: The recent articles showed a kind of associations of the serum vitamin D levels and chronic diseases, for example, autoimmune diseases, vascular disorders, as well as malignancies. Also vitamin D deficiency impacts normal growth and maximal bone mineral accretion in puberty. Of pediatric population in Korea, the prevalence of cases of vitamin D deficiency and precocious puberty were continuously increasing nowadays.Objective and hypotheses: W...

Hypocalcemia is a common metabolic problem and a recognized cause of seizures in neonates and infancy. Breastfed infants born to mothers who are vitamin D and or calcium deficient are at risk of developing vitamin D deficiency and hypocalcemia.Case report: We present two infants (two weeks old boy and a 9-month-old girl) with hypocalcemia caused by vitamin D deficiency admitted to our pediatric emergency department for seizures and tetan...

Background: According to the latest studies vitamin D has an effect on the production and/or secretion of IGF1 in the liver, but the exact mechanism regulating these relationships has not been thoroughly explained.Objective and hypotheses: Evaluation of the relationship between 25(OH)D and IGF1 levels in the serum of children with GH deficiency (GHD).Method: The study group consisted of 76 GH deficient children qualified for GH the...

Background: Diabetes mellitus type 1 (T1DM) is the most common chronic diseases in children. Studies show that the prevalence of vitamin D deficiency is higher in this group of patients.Objective and hypotheses: The aim of this study was evaluation HbA1C and IGF-1 levels in children with T1DM that receiving vitamin D supplement.Method: A total of 30 diabetic children 5–15 years with 25(OH) D levels lower than 74 nmol/l (29 ng/...

Background: Low vitamin D levels have been linked to stunted growth and lower bone mineral density. Vitamin D insufficiency is a recognised condition in children in the UK. However, optimal levels of vitamin D are not adequately defined and guidance regarding supplementation is also limited.Aim: To identify vitamin D levels in a select cohort of Caucasian children aged 0–16 years, and describe how preterm birth, obesity, age and malabsorptive condit...

Introduction: The physiological process by which vitamin D regulates calcium and phosphorus metabolism, the major mineral constituents of bone tissue, is by far very well understood. However, the clinical implementation of vitamin D deficiency on bone fragility in childhood remains controversial.Objective: The aim of this case-control study is to investigate the prevalence of vitamin D deficiency among Lebanese children who experienced a ‘low-energy...
