Introduction: Neonatal diabetes, defined as the onset of diabetes within the first six months of life, is very rare disease. Several genetic factors caused to neonatal disease have been identified to date. PTF1A (pancreatic transcription factor 1a) play a key role in early pancreas development and cerebellar neurogenesis. Biallelic mutations in PTF1A have been reported in patients with pancreatic and cerebellar agenesis, whereas mutations loc...

Introduction: X-linked adrenoleukodystrophy (X-ALD) is a rare autosomal recessive neurodegenerative disease caused by a mutation in the ABCD1 gene. Although its clinical presentation varies, X-ALD is generally characterized by progressive demyelination of the central nervous system, primer adrenal insufficiency, and elevated plasma very long-chain fatty acid (VLCFA) levels. Herein, we aimed to present a case of X-ALD with normal VLCFA caused by a path...

Introduction: Proopiomelanocortin (POMC) deficiency is a rare disease characterized by central adrenal insufficiency, early-onset obesity, red hair, and impaired skin pigmentation. This disease is caused by mutations of POMC that is localized in 2p23.3. Here, we aimed to present a case with central adrenal insufficiency, red hair, and rapid weight gain and who was detected frameshift mutation in the POMC.Case</s...

Introduction: Testicular regression syndrome (TRS) is a rare disease characterized by testicular dysfunction that causes varying degrees of virilization defect according to the emergence period in fetal life. The majority of cases present with normal male external genitalia. However, ambigious genitalia or, more rarely, female external genitalia can be found depending on the extent and timing of the intrauterine accident. Here, we present a case of TRS with no...

Introduction: In the last 10 years, blue light (BL) sources such as tablets and phones has increased in every age group. Especially due to the Covid-19 pandemic, screen exposure has also increased in childhood. However, the effects of BL exposure in the puberty process aren’t clear. We aimed to examine the effect of BL exposure and exposure time on pubertyMethods: Immature eighteen 21-day-old female Sprague Dawley ...

Giant prolactinomas are rare tumours, with a prevalence of 0.5–4.4% among all pituitary tumours. In the literature, relatively few series describing their management and outcomes are available; moreover, only individual case reports of giant prolactinomas in children have been documented. We report a 10-year-old boy presented with painless progressive vision loss, insidious in onset, and bitemporal headache of six mounths duration. On physical examination; height: 134.2 ...

Glutamic acid decarboxylase (GAD) is the enzyme that catalyzes the conversion of L-glutamat into GABA, one of the classical neurotransmitters with neuroinhibitory function. GAD is present in GABAergic neurons and in pancreatic beta cells. It is remarkable that Anti-GAD antibody(Anti-GADab) can have different disease manifestations, i.e., Type 1 diabetes mellitus (T1DM), Stiff-Person Syndrome, limbic encephalitis (LE), epilepsy. Cooccurence of T1DM and LE is reported in the lit...

Introduction: Prohormone convertase (PC) is a calcium-dependent serine endoprotease. PC 1/3 is responsible for converting hormones and neuropeptitids which has role on energy homeostasis, food intake,glucose metabolism (a-MSH, CART, NPY, AgRP, Orexin, Hypocretin, Ghrelin, insulin, cholecystokinin, GLP-1, GHRH, GnRH, ACTH, TRH) from proforms to active form. PC 1/3 deficiency’s clinical signs are diarrhea that started in the newborn period, obesity, hypoglycemia, multiple ...
