Backgrounds: The understanding of the efects and role of vitamin D and its analogues in the functioning of body tissues, systems and organs has improved substantially over the last decade. The potential extra-skeletal role of vitamin D has been a rich area of interest and research over the last decade. Vitamin D deficiency has been implicated in a variety of chronic diseases, including bone mineral disease, autoimmunity, cancer, and diabetes. Many epidemiologi...

Background: Nutritional rickets is a disorder of defective chondrocyte differentiation and mineralization of the growth plate and osteoid due to vitamin D deficiency with or without low calcium intake in growing children. Maternal Vitamin D deficiency and exclusive breastfeeding without supplementation are the most frequent causes of rickets in the infancy. Vitamin D deficiency is still a problem in Sri Lanka in spite of sun shine throughout the year. We present a case series ...

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...

Background: The serum 25-hydroxyvitamin D (25OHD) levels are known to be lower in obese children, probably due to sequestration of vitamin D in the adipose tissue. However, there is no consensus on the dose adjustment for vitamin D supplementation in obese children with vitamin D deficiency (VDD).Aims: To compare the response to vitamin D replacement in normal weight vs overweight children with VDD, and to investigate the determinant for increment of 25O...

Background and Aim: Vitamin D plays a crucial role in skeletal and extra-skeletal physiology. It is essential for growth, development and health. It works as a paracrine and autocrine signaling molecule that affects nearly all systems in the body. Vitamin D deficiency (VDD) is prevalent in many countries in all age groups, and may be overlooked due to the variable clinical presentations according to age. This study was conducted to assess vitamin D status amon...

Vitamin D supplementation is recommended for breastfed infants as primary prevention of vitamin D deficiency and nutritional rickets. Globally, the most commonly recommended dosage of vitamin D is 400 IU/day for healthy breastfed infants. Whether there are benefits of higher dosages of vitamin D to infant bone mass and body composition has been investigated. The objective of this presentation is to review the evidence from randomized controlled trials conducted in healthy term...

Aım: İn this prospective planned study, it was aimed to study relationship between vitamin D level and vitamin D receptor gene polimorphism in patients with type l DM aged 0–18 years old.Methods and materials: We enrolled total 165 children in which 101 new and old diagnosed to WHO criterias TIDM patients from 0–18 years old and 64 chıldren as control group who were matched with gender and age. İn all cases serum Ca, P, PT...

Objective: To evaluate the level of 25 (OH) D – vitamin in obese adolescents living in the South of Russia.Materials and method: We examined 20 obese adolescents with varying degrees of severity, aged 15.5±0.3 years, ten girls and boys. The comparison group consisted of ten healthy adolescents matched for age and sex. Obesity was calculated by BMI. Level of 25-(OH) D – vitamin was studied in the laboratory by ELISA (nmol/l). Furthermore, t...

Introduction: The circadian rhythmicity of the hypothalamic–pituitary–adrenal (HPA) axis depends on the synchronization of the clock molecular systems in the suprachiasmatic nucleus and in the adrenals. When and how this process occurs in the adrenal is unknown.Objective: To assess the ontogeny of daily variation of the expression of the adrenal clock genes (Clock, Arntl, Per1, Per2, Per3, Cry1, Cry2, Rora, and Nr1d1), steroid...

Case presentation: A 2-year-boy was referred tour hospital for the rickets. He was the first son between non-consanguineous parents and fed with breast milk. But after weaning, he was avoided from taking egg, dairy products including cow’s milk. He was also suffered from developmental delay and had strong food preference. He could take only two kinds of foods, steamed rice and soy bean product, tofu. X-ray findings showed typical rachitic change on long bone metaphysis. L...
