Background and Aim: Achondroplasia is the most common skeletal dysplasia and is associated with serious complications such as foramen magnum stenosis (FMS). Current guidelines in Germany recommend polysomnography at 2-3 months and cranial imaging at 6-9 months of life in achondroplasia, whereas American Academy of Pediatrics recommends to evaluate every infant with achondroplasia for cranio-cervical junction risks via neurologic examination, polysomnography an...

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: Neurokinin B and kisspeptin appear to play main roles in puberty.Aims and objectives: The aim of the present study was to investigate the diagnostic role of kisspeptin and neurokinin B in central precocious puberty (CPP) and premature thelarche (PT).Methods: The girls who presented with breast development (between 5 and 8 years) were included in the study. All cases underwent bone age (BA) assesment. Basal serum FSH, LH...

Background: False-negative results can occur an extremely high level of substrate at the assay system. This is called the ‘high-dose hook effect’.Case presentation: 14 year-old female patient was referred with short stature, amenorea and hirsutism. Height, weight and blood pressure were 140.5 cm (SDS:−3.5), 43.4 kg (SDS:−1.6) and 120/80 mmHg. She had stage 1 Tanner breast, stage 5 pubic hair and hirsutism (mFG scale: 28) with androi...

Background: Spexin (SPX)and kisspeptin (KISS) are peptides involved in the regulation of body weight, metabolism and reproduction.Aim: To assess expression levels ofSPX andKISS in serum, ovarian tissue and white adipose tissue (WAT) of female albino Wistar rats as related to pubertal status and metabolic surrogates of puberty.Materials and Methods: Twenty-six female albino Wistar r...

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...
