Introduction: X-linked adrenal hypoplasia congenita (AHC) is caused by mutations of the NR0B1 gene encoding DAX1 on chromosome Xp21. AHC also occurs as part of a contiguous gene deletion syndrome together with Duchenne muscular dystrophy, glycerol kinase deficiency (GKD), mental retardation, or a combination of these conditions. Here, we report a male 5 years old with AHC who presented with adrenal insufficiency, GKD, and duchenne muscular dystrophy due to a mutation in the DA...

Background: X-linked dominant hypophosphatemic rickets (XLHR) is a rare hereditary metabolic bone disorder. Calcitriol and phosphates are used for the treatment and hyperparathyroidism rarely occurs as a complication. We report a case of XLHR who developed autonomous parathyroid hyperfunction during treatment and underwent surgery for that.Case: A male patient was presented with short stature and bone deformities at age 11 months and diagnosed with XLHR ...

Background: Klinefelter syndrome, also known as 47, XXY, is a disorder characterized by tall stature, hypogonadism and mental retardation which is caused by nondisjunction events during meiosis and occurs in 500–1 000 live male birth. Here we report a patient with Klinefelter syndrome who presented with short stature, in contrast to common tall stature presentation and was diagnosed with GH deficiency.Case: A 7-year-old male presented with short sta...

Background: Monocarboxylate transporter 8 (MCT8) is a specific transporter of triiodothyronine (T3). MCT8 gene mutations cause a rare X-linked disorder known as Allan–Herndon–Dudley syndrome, characterized by thyroid dysfunction (high T3, low T4, and normal/high TSH) and psychomotor retardation.Case report: A 4-year- and 9-month-old boy, who was already having L-T4 treatment fo...

Introduction: Hyperparathyroidism is a disorder usually seen in adults and rarely in childhood.Case: A 14 years and 7 months old girl complaining of constipation applied to pediatric gastroenterology department was consultant to pediatric endocrinology department due to increased plasma calcium levels. She was healthy previously and had no vitamin D usage. In her physical exam; body weight: 53.8kg (-0.12 SD), height: 153,5cm (-1.32 SD), ...

Introduction: Craniopharyngiomas can lead to pituitary insufficiency and long-term endocrine complications due to the location, invasive character and risk of recurrence, besides they known as histologically benign.Aim: In this study, we aimed to evaluate the demographic, clinical features, endocrinological problems and follow-up findings in patient with craniopharyngioma in childhood.Metho...

Introduction: 5-Hydroxymethylfurfural (HMF) is formed when sugars like glucose and fructose are heated in the presence of amino acids. HMF is naturally present in many foods and we are exposed to HMF in daily life. There are conflicting data on potential genotoxic, mutagenic, carcinogenic, DNA-damaging, organotoxic and enzyme inhibitory effects of HMF and its metabolites. We aimed to investigate toxic effects of HMF on reproductive system in peripubertal rats....

Introduction: A rare cause of diabetes mellitus is Wolfram Syndrome, which arises from mutations in wolframin gene found on chromosome 4. Optic nerve atrophy, diabetes insipidus, sensorineural deafness, psychiatric problems can accompany diabetes mellitus, so it can be also named as DIDMOAD syndrome. Hypergonadotrophic hypogonadism can be rarely observed in Wolfram syndrome. A case of novel homozygous mutation in the wolframin gene has been reported because of concomitant rare...

Introduction: The most common type of diabetes in childhood is type-1 diabetes. The group of diabetes called MODY (maturity-onset diabetes of the young) is rarer. Mutations that occur in glucokinase gene cause disruption in the perception of the resultant glucose level and, consequently, impaired insulin release, leading to the development of MODY-2. In this case, resulting hyperglycemia is usually at a mild, non-progressive level and does not require insulin therapy. For this...

Neonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes presenting in the first 6 months of life. NEUROD1 is a transcriptional factor involved in the development of endocrine pancreas. A few patients with maturity onset diabetes of the young (MODY) due to heterozygous NEUROD1 mutations and only two cases with permanent NDM (PNDM) associated to neurological disorders and cerebellar hypoplasia due to homozygous mutations in the NEUROD1 gene have been reported.<...
