Introduction: Although the majority of the cases with obesity have a multifactorial etiology, rare monogenic forms of obesity exist. Several genetic disorders have been described that lead to early onset monogenic obesity. Leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), proprotein converting protein subtilisin / kexin-type 1 (PCSK1) and proopiomelanocortin (POMC) are the genetic mutations that have been most frequently shown to cause mono...

Introduction: Galanin is a neuropeptide involved in the regulation of food intake and glucose homeostasis. The objective of this study was to assess the relation of serum galanin levels with anthropometric and metabolic parameters in obese and healthy children.Material and methods: This cross-sectional study consisted of 38 obese children (mean age, 11.9±3.0 years) and 30 healthy children (mean age, 11.4±2.0 years). Clinical and biochemical [gl...

Background: Klinefelter’s syndrome (KS) is the most prevalent chromosomal abnormality and clinically characterized by oligo-azoospermia, hypergonadotropic hypogonadism, gynecomastia and infertility in adults. Genital malformations in KS have rarely been reported.Objective and hypotheses: To investigate the etiology of penoscrotal hypospadias in a 14-month-old boy.Method: The patient was born from a healthy 23-year-old mother a...

Background: Neonatal severe primary hyperparathyroidism (NSHPT, MIM 23900) is a potentially lethal autosomal recessive disorder characterized by severe hypercalcemia, markedly elevated serum PTH levels and skeletal abnormalities that include multiple fractures, demineralization and erosions. It is secondary to biallelic loss of function mutation in the CASR gene that encodes the calcium sensing receptor.Case presentation: We identified a 10-day old baby ...

Introduction: Fanconi-Bickel syndrome (FBS), is a rare autosomal recessive disorder of carbohydrate metabolism (FBS, OMIM 227810), caused by defects in the facilitative glucose transporter glut-2, which transports glucose in and out of hepatocytes, pancreatic β cells and basolateral membranes of intestinal and renal epithelial cells. Characteristic features include growth failure, hepatomegaly, glucose and galactose intolerance, fasting hypoglycemia, and renal tubular nep...

Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...

Background: Laron syndrome is an autosomal recessive disease caused by molecular defect in GH receptor gene. The patients have severe growth retardation and clinical features of GHD with low IGF-1, high basal GH and failed response to IGF-1 stimulation test. The only proved treatment is daily recombinant IGF-1 administration which showed improvement in linear growth.Aim: To describe the largest group of patients with lar...

Objective: We aimed to evaluate the relation between the peak growth hormone (GH) levels on provocative tests and response to recombinant human GH (rhGH) therapy in patients with GH deficiency (GHD).Methods: This was a cross-sectional, single-center, and retrospective study. A total of 518 patients who received rhGH therapy under the age of 16 in the Endocrinology Clinic of Akdeniz University Hospital between 1997 and 20...

Introduction: Congenital adrenal hypoplasia, a rare cause of childhood primer adrenal insufficiency, is caused by defects in transcription factors involved in the development of adrenal gland. One of them is the NROB1 (DAX1) gene, localized in Xp21.2. DAX1 mutations have been identified that cause X-linked adrenal hypoplasia congenita. Infants affected with X-linked adrenal hypoplasia congenita may present with salt-wasting, micropenis or cry...

Background: Low-dose adrenocorticotropic hormone stimulation test (LDST) is commonly used for evaluating the adequacy of hypothalamo-pituitary-adrenal axis functions. However, there is still no standardization between protocols used in different centres.Objective: To contribute to the optimal time of highest cortisol response in the LDST in children.Design: A prospective study of L...
