Introduction: Van Wyk Grumbach Syndrome (VWGS) is characterized by untreated severe hypothyroidism, isosexual precocious puberty, multiple ovarian cysts and delayed bone age. The disorder is most likely due to complex interactions of the hormonal axis; (1) excess TSH stimulates the FSH-receptor, (2) pituitary enlargement and hyperstimulation, (3) secondary ovarian hyperstimulation. Although it is extremely rare, it is important to recognize before the unnecess...

Dysosteosclerosis (DOS) is a rare form of dense bone disease and, short stature, recurrent fractures, optic atrophy, cranial nerve palsy, developmental delay, flattened fingernails, skin related complications, and failure of tooth eruption are the characteristic features of the disease (MIM %224300). Irregular osteosclerosis, flattened diffusely dense vertebral bodies, sclerotic skull, radiolucent sub-metaphyseal portions of the long tubular bones with sclerotic diaphysis are ...

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...

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...

Backgrounds/Aims: Studies related to changes in thyroid hormone metabolism in the course of chronic liver diseases have been conducted mostly in adults. In this study, we aimed to investigate the thyroid dysfunction in childhood chronic liver diseases.Methods: Between 2005 and 2018, 960 chronic liver disease patient file that followed in our gastroenterology department are reviewed. Among all study subjects, 107 (53 fema...

Introduction: The most common causes of hyperthyroidism in the pediatric age group are autoimmune conditions (Graves' disease or Hashitoxicosis). Hyperfunctioning thyroid carcinomas are rarely reported. In this case report, we present a 17-year-old girl who was diagnosed with papillary thyroid carcinoma upon testing for hyperthyroidism.Case: A 17-year-old girl had presented to another center with a 1-month history of...

Introduction: Mutations in FGFR1, which is involved in formation and migration of neurons responsible for the production of gonadotropin-releasing hormones, may either cause isolated hypogonadotropic hypogonadism (HH) or Kallmann syndrome (KS). In addition, FGFR1mutations were reported in 2.7% of the cases with multiple pituitary hormone deficiency.Case: A 16-year-old male was referred to our clinic...
