Stoeva Iva , Mihova Kalina , Koleva Reni , Zheliaskov Mitko , Stoilov Boris , Kaneva Radka

Of the several genetic defects responsible for thyroid dyshormonogenesis, mutations in TPO gene are the most prevalent causes of inherited defects in CH. Prevalent mutations are in exons 8-11 (catalytic site).Case presentation: Girl, born at 16d after term, before the introduction of the neonatal screening, with asphyxia, BL 55 cm, BW 4 kg. Because of insufficient weight gain, feeding difficulties, prolonged jaundice she was referred to a pediatric endoc...

Vitamin D Deficiency in Children

Dobrescu Andreea , Chirita-Emandi Adela , Papa Maria , Puiu Maria

Background: Vitamin D deficiency has a high prevalence in children. It is produced by the skin from exposure to sunlight but its synthesis is influenced by many external and internal factors.Objective and hypotheses: The study aims to evaluate vitamin D in children with different pathology and highlights the influencing factors of it.Method: We evaluate 25-hydroxyvitamin D levels in 84 patients, sex ratio 1.15:1, aged between 3 mon...

Vitamin D, OPG in Obese Children

Mikhno Hanna , Solntsava Anzhalika

Objective: Determination of changes in metabolic status and vitamin D concentrations in obese children.Methods: We examined 210 children in the University Hospital (Minsk) from 2021 to 2022 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of vitamin D, OPG, insulin were determined. All children were divided into 2 groups: group 1 children with morbid obesity (MO) ...

Objective: determination of changes in metabolic status and vitamin D concentrations in obese children.Methods: We examined 221 children in the University Hospital (Minsk) from 2019 to 2021 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of vitamin D, insulin were determined.

Maternal, rather than fetal, genetic variation in vitamin D metabolism is associated with umbilical cord blood 25-hydroxyvitamin D in pregnancies supplemented with cholecalciferol: findings from the MAVIDOS randomized controlled trial

Background: Neonatal vitamin D deficiency (VDD) can result in symptomatic hypocalcemia, seizures and cardiomyopathy and has been associated with reduced bone mineralization in childhood, but is potentially preventable with antenatal cholecalciferol supplementation. Single nucleotide polymorphisms (SNP) in the vitamin D metabolism pathway are associated with serum 25-hydroxyvitamin D [25(OH)D] in adulthood. We assessed whether maternal and/or offspring SNPs in ...

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: Vitamin D, mainly important in calcium phosphate homeostasis and bone health, has been recently suggested as an important factor in pathogenesis of numerous chronic conditions such as type 2 diabetes, metabolic syndrome and polycystic ovarian syndrome (PCOS).Objective and hypotheses: The aim of this study is to investigate the relation between PCOS and premature adrenarche (PA), suggested as predictor of PCOS.Method: A ...

The effects of vitamin D supplementation on infant bone mass and body composition

Weiler Hope A.

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...

ABCC8 MODY in an Obese Adolescent Misdiagnosed with Type 2 Diabetes

Filibeli Berna Eroglu , Çatli Gönül , Manyas Hayrullah , Ayranci Ilkay , Kaya Özge Özer , Dündar Bumin

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...

The Effect of Stimulatory G Proteins on Differentiation within the Growth Plate

Bastepe Murat

Endochondral bone formation regulates bone growth both during embryonic development and after birth. Several different autocrine/paracrine or hormonal mechanisms govern the regulation of endochondral bone formation. Among those is the pathway involving stimulatory G protein, which primarily mediates the actions of parathyroid hormone-related peptide (PTHrP) in the growth plate. PTHrP is synthesized in the perichondrial cells and chondrocytes at the end of bones. In the growing...
