Context: Nutritional vitamin D deficiency is rare in the high income countries; its manifestations are usually associated with the combination of accompanying risk factors, as malnutrition, chronic illness, dark skin or restricted exposure to sunlight due to cultural practices.Objective: The aim of this case report is to increase the awareness to severe vitamin D deficiency as a result of extreme indoor isolation due to ...

Aim: Case report of an 18-month-old child with a background of vitamin D dependent rickets type 1(VDDR1)], due to a mutation of CYP27B1 (c.1319_1325dup and c.335C>T: compound heterozygote).Methods: Presentation of the case and the management of hypocalcemia as well as the complications of follow-up.Results: The patient presented at the A&Es of the 2nd Department of Pediatric...

Background: Decreased serum 25-hydroxyvitamin D (25-OHD) level has frequently been reported in obesity, a condition which is associated with insulin resistance. Insulin resistance was negatively associated with serum 25-OHD. Puberty is the period with altered insulin sensitivity. Previous studies showed conflicting results of the variation of serum 25-OHD levels across pubertal stages. However, data on serum 25-OHD levels across pubertal stages in obese childr...

Abnormal DNA methylation contributes to tumor progression and is emerging as a prognostic marker in several types of cancers. To investigate whether DNA methylation is associated with pediatric adrenocortical tumor (pACT) presentation and patient prognosis, we analyzed the methylation profile of 57 tumors (MethylationEPIC BeadChip Array-Illumina) and patients’ clinicopathological features and outcome. The study comprehended 40 girls and 17 boys, with median age at diagnos...

Background: Generally, diabetic nephropathy onsets and progresses within 5–10 years after DM onset resulting in chronic kidney disease (CKD) causing death in every 4–5th patient with type I DM. Molecular-genetic studies of endogenous/genetic CKD risk factors are of high relevance in understanding of pathogenetic mechanisms underlying formation of nephrosclerosis, and in improvement of interventions.Objective and hypotheses: To assess renal func...

Background: Adipose tissue (AT) in obesity is characterized by low grade inflammation. The apoptosis inhibitor of macrophages (AIM; also called CD5L) is incorporated into adipocytes leading to increased lipolysis. Excess AIM-dependent lipolysis induces adipose tissue macrophage recruitment. M1 (proinflammatory) macrophage infiltration, with surface marker CD40, correlates with metabolic complications.Objective and hypotheses: To study serum levels and AT...

Background: Type 1 diabetes mellitus (T1DM) is an autoimmune and inflammatory process and vitamin D (VD) is thought to reduce inflammation and prevent autoimmune destruction. Studies have shown that VD has an effect on insulin secretion and sensitivity in rats. And it has been shown that adult T2DM with normal levels of VD have decreased insulin requirements. Two prior studies in Turkey looked at the relationship between VD levels and daily insulin requirement in paediatric pa...

Objective and hypotheses: The work was initiated to assess functional condition of the kidneys and to study interrelation between ACE gene I/D polymorphism and stage of chronic kidney disease in children and adolescents with type 1 diabetes mellitus (DM) in compliance with K/DOQI recommendations (2002).Method: We examined 120 children and adolescents with type 1 DM, 53 (44.2%) males and 67 (55.8%) females among them (mean age 13.8±0.24 years. GFR wa...

Background: PHP is a rare heterogeneous genetic disorder causing parathyroid hormone (PTH) resistance. This condition is caused by deficiency of the α subunit of the protein Gs, encoded by GNAS gene. Clinical classification is based on presence or absence of Albright hereditary osteodystrophy (AHO) and multiple or single hormone resistance, to PHP1a/1c and PHP1b respectively.Objective: To describe the clinical and practical management of a case of P...

Background: Congenital hyperinsulinism (CHI) is a chronic and complex rare endocrinopathy with dysregulated insulin secretion causing severe and recurrent hypoglycemia resulting in adverse neurologic and developmental sequelae in children. Current treatment options are limited and often inadequate to treat CHI. Dasiglucagon (DASI), a glucagon analog administered by subcutaneous continuous infusion, has demonstrated reduction in glucose infusion rate (GIR) in P...
