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: GH deficiency (GHD) occurs in one in 4000–one in 10 000 children, but can also be diagnosed in adults.1 GHD therapy typically requires injections over a period of years.2 Adherence to long-term GHT presents a challenge.Objective and hypotheses: This study describes the rates of adherence to GHT among patients with GHD.Method: Members who were continuously enrolled 6 months pre- and 12 months p...

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...

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...

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...

Background: The most common single nucleotide polymorphism in the IGFBP3 promoter region occurs at position -202. This polymorphic variation occurs frequently and may influence GH responsiveness and somatic growth.Objective and hypotheses: This study aimed to assess the effects of IGFBP3 promoter polymorphism on growth in children.Method: Restriction fragment length polymorphism (RFLP)-based genotyping of the -202 single nucleotide...

We report and discuss a case of a girl who at birth underwent surgery for Hirschsprung Disease (HD). To closely investigate her condition, we used a Next Generation Sequencing (NGS) panel to carry out a study of some of the genes known as being associated with congenital megacolon (PHOX-2B, RET, EDN3, GDNF, ASCL1 and BDNF). This analysis showed a maternally inherited heterozygous variant in the RET protooncogene (c.734T>A, p.Val245Glu), which is not described in the scienti...

Background: Studies examining vitamin D levels in association with childhood obesity usually do not concurrently measure levels of vitamin D-binding protein and do not calculate the unbound, bioavailable vitamin D, that is considered the fraction of 25-hydroxyvitamin D able to exert biological activity.Objective and hypotheses: To evaluate in a group of children for the most part obese i) the concentrations of both total 25-hydroxyvitamin D and of the bi...

We report on a 17-year-old female patient with cramps in hands and legs since 6 months. She showed hypokalemia with high need of potassium substitution (128mmol K= 1.3 mmol/kg/d), arterial hypertension (mean 154.5/92 mmHg), polydipsia and polyuria without nocturia or salt craving. Her PMH revealed neuroblastoma stage III with high-dose chemotherapy, stem cell transplantation and obesity (36.8 kg/m2). Further investigation showed aldosterone 77.5 ng/dl (norm values: 2-10ng/dl),...
