Hanedan Onan Sertac , Demirbilek Huseyin , Aldudak Bedri , Bilici Meki , Demir Fikri , Muhtar Yilmazer Murat

Background: Acute rheumatic fever (ARF) is a non-suppurative complication of Group A beta-hemolytic streptococcus pharyngitis. The underlying mechanisms have not been fully elucidated. A series of autoimmune processes are thought to be involved in pathogenesis. Low vitamin D levels have been reported in various autoimmune diseases.Objective and hypotheses: The aim of the present study is to evaluate the association of vitamin D levels and its impact on t...

Does Vitamin D Affect Mean Platelet Volume Values or Not

Bulan Keziban , Dogan Murat , Kaba Sultan , Aslan Oktay

Objective: Platelets play a key role in the development and progression of cardiovascular disease. The degree of platelet activation may be assessed by platelet indices such as platelet count, mean platelet volume (MPV) and platelet distribution width (PDW). In addition, both epidemiological and in-vitro studies have linked vitamin D deficiency to enigmatic disease including cardiovascular disease however a clear mechanistic link remains missing. In present study, we ...

Vitamin D Levels in Short Prepubertal Children Born Small for Gestational Age

Korpal-Szczyrska Maria

Background: Adequate vitamin D level is essential for optimal child’s growth. Small for Gestational Age (SGA) is a common cause of short stature in childhood. Being born SGA is associated with a risk of developing insulin resistance.Objective and hypotheses: The aim of the study was to evaluate serum vitamin D levels in short children born SGA and appropriate for gestational age (AGA) and to assess their relationship with insulin sensitivity.<p ...

Neonatal Seizures Neonatal due to Hypocalcemia Secondary to Maternal Vitamin D Deficiency

Campos-Martorell Ariadna , Narvaez Karla , Clemente Maria , Yeste Diego , Mogas Eduard , Gerones Laura , Carrascosa Antonio

Background: Vitamin D is an essential hormone in the homeostasis of calcium. Its main source is sun exposure. Changes in lifestyle and migratory movements have favored the reappearance of vitamin deficiency in our country.Method: We present three cases of newborn with hypocalcemic seizures, secondary to maternal vitamin D deficiency. Mother’s origin was North Africa.Results: Case 1: 7 days old male brought for several episodes...

Does Vitamin D Influence Energy Metabolism in Children and Adolescents?

Wedrychowicz Anna , Sztefko Krystyna , Starzyk Jerzy

Background: Recent years bring a lot of data of the important role of vitamin D in different physiological processes, including a prevention from pathological states.Objective and hypotheses: The aim of the study was to analyze associations between serum level of vitamin D and some markers of glucose and lipid metabolism but also as well bone-related molecules as adipokines and in children and adolescents.Method: 57 patients, 40 wi...

Mutations in MAGEL2 and L1CAM are Associated with Congenital Hypopituitarism and Arthrogryposis

Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...

The association between physical activity and 25-OH vitamin D levels

Zeynep Altun Ekin , Bilir Pelin , Torel Ergur Ayca

In children and adolescents, vitamin D deficiency negatively affects muscle physiology, exposing them to increased muscle damage and pain, stress fractures, and tendon structures. In addition, free radicals released when the body is exposed to oxidative stress after exercise can cause DNA damage. Vitamin D plays an important role in removing these radicals. The purpose of this study is to investigate the relationship between physical activity and 25- OH vitamin D in obese chil...

A Rare Form of Vitamin D Receptors Dysfunction (vitamin D-dependent Rickets Type II) with Alopecia. A Case Report

Ahmed Shayma , Soliman Ashraf , Elawwa Ahmed , Hamed Noor , Alaaraj Nada

Introduction: VDDR II is an autosomal recessive disorder caused by a defect in the vitamin D receptor gene located on chromosome 12q12–q14. Thus far, 13 mutations have been identified. It is characterized by hypocalcemia, secondary hyperparathyroidism, and early onset severe rickets. Here we report a case of a severe form of rickets associated with alopecia.The Case: This 23-month-old boy was born at term to consang...

The relationship between acanthosis nigricans and vitamin D in obese children and adolescents

Zeynep Altun Ekin , Ergur Ayca Torel , Bilir Pelin ,

Studies show that vitamin D deficiency can have negative effects on glucose homeostasis, although the mechanism for this is still unclear. The possible mechanism may be related to the presence of vitamin D receptors and their metabolizing enzymes in insulin-sensitive cell types, such as pancreatic cells and adipocytes. The aim of this study is to compare how serum 25- OH D level and HOMA-IR index are related to acanthosis nigricans (AN) and which of them is a better marker for...
