Autoimmune polyglandular syndrome (APS), on the other hand, is a cluster of endocrine disorders resulting from immune dysregulation, often accompanied by damage to non-endocrine organs. There are 2 types of APS: type 1 and type 2 (APS-1 and APS-2). Type 2 APS is characterized by the development of organ- and tissue-specific antibodies. In those with Addison's disease, antibodies to the 21-hydroxylase enzyme found in the adrenal cortex are present in more than 90% of patie...

A defect in one of the 5 enzymes related to the cortisol biosynthesis pathway (cholesterol side chain degradation enzyme, 3-beta-hydroxysteroid dehydrogenase, 17-hydroxylase, 21-hydroxylase and 11-hydroxylase) is responsible for the formation of KAH. Congenital Adrenal Hyperplasia (CAH) is seen in newborn babies with a frequency of 1/10,000-16,000. The most common 21 hydroxylase enzyme deficiency. 3-β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of ...

Aim: The pathophysiology of developing hypophosphatemia in children with diabetic ketoacidosis (DKA) has not been sufficiently elucidated. Fibroblast Growth Factor 23 (FGF23) is a hormone that causes phosphate excretion from the kidneys. The increase of FGF23 in children with DKA may explain the pathophysiology of hypophosphatemia in these children. The aim of our study was to investigate the effect of serum FGF23 on serum phosphorus level in children with DKA...

Background: Thyroid nodules are less common in childhood but it has higher risk of malignancy. In this study, we aimed to evaluate children and adolescents with thyroid nodules, clinically, radiologically and histopathologically to determine etiologic distrubution.Method: Seventy-one patients (46 females) with the mean age of 10.41±5.03 (0.04–21) years with thyroid nodules were involved in this study. Patients were evaluated by their complaints...

Background: Wolcott–Rallison syndrome (WRS) is an autosomal recessive, multi-system disorder with early onset diabetes in infancy. It is associated with clinical features that show variability between WRS cases. Clinical data are still scarce.Patient data: A 9 year old girl followed-up due to diabetes and growth failure since 2 months of age from another centre presented with ketoacidosis and multi-organ failure. After resolution of her decompansate...

Background: Although it is known that hypoglycaemia could cause severe negative effects on brain development and also infantile spasm, it has not been reported that transient hyperinsulinaemic hypoglycaemia, which spontaneously improves over a short time, may cause infantile spasms. Infantile spasm is a disorder of early childhood typically seen in first year of life characterized by the occurrence of sudden, brief, generally bilateral and symetric motor spasms of muscles of t...

Spondyloocular syndrome (OMIM 605822) is an autosomal recessive disorder characterized by skeletal complaints (osteoporosis, platyspondyly, multiple bone fractures), hearing loss and ocular symptoms (cataracts, retinal detachment). XYLT2 gene (OMIM 608125) mutation encoding xylosyltransferase II enzyme which is responsible from the first step of proteoglycan assembly is responsible for the pathogenesis. Phenotypical variability is associated with varying genetic expre...

Background: Adrenal hypoplasia congenital associated with DAX-1 (NROB1) gene mutations is a rare cause of primary adrenal insufficiency in male. It can be presented as a part of Xp21 contiguous gene deletion syndrome which characterized by complex glycerol kinase deficiency (GK), adrenal hypoplasia congenital (NROB1), intellectual disability (IL1RAPL1) and/or Duchenne muscular dystrophy (DMD).Case report: We report a 6-month-old male infant, which presen...

Background: GnRH agonists, leuprolide acetate (LA) and triptorelin acetate (TA), have been widely used in the treatment of central precocious puberty (CPP). But, a comparative data on the effectiveness of these two drugs for CPP treatment is very scarce.Objective: To compare the efficacies of TA and LA treatments in girls with idiopathic CPP.Patients and Methods: Sixty girls with rapidly progressive CPP treated with LA (n=...

Background: The familial type of isolated GH deficiency (IGHD) is characterized by a variable degree of growth restriction, low but detectable GH serum concentrations. The recessive type 1A and 1B, the autosomal-dominant type 2, and X-linked recessive type 3. Phenotype-genotype correlations are notoriously difficult to be established.Objective and hypotheses: Herein, we described the variable clinical status of a family with a novel GH1 mutation which is...
