Background: GnRH agonists, leuprolide acetate (LA) and triptorelin acetate (TA), have been widely used in the treatment of central precocious puberty (CPP). But, a comparative data on the effectiveness of these two drugs for CPP treatment is very scarce.Objective: To compare the efficacies of TA and LA treatments in girls with idiopathic CPP.Patients and Methods: Sixty girls with rapidly progressive CPP treated with LA (n=...

Background: The familial type of isolated GH deficiency (IGHD) is characterized by a variable degree of growth restriction, low but detectable GH serum concentrations. The recessive type 1A and 1B, the autosomal-dominant type 2, and X-linked recessive type 3. Phenotype-genotype correlations are notoriously difficult to be established.Objective and hypotheses: Herein, we described the variable clinical status of a family with a novel GH1 mutation which is...

Background: Idiopathic hypogonadotropic hypogonadism may be normosmic (nIHH) or it may be associated with anosmia, which is known as Kallmann syndrome (KS). First mutation GNRH1 was described in 2009 in patients with nIHH. Mutations of the human GNRH1 gene are a very rare cause of nIHH, with only six mutations so far described.Case: The proband is a 11.3-year-old boy who first presented at age 1 with micropenis and cryptorchidism. His p...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Background: The steroidogenic acute regulatory protein (StAR) has been shown to be essential for steroidogenesis by mediating cholesterol transfer into mitochondria. Inactivating StAR mutations cause the typical clinical picture of congenital lipoid adrenal hyperplasia.Objective and hypotheses: We aimed to identify causative mutations in cases presenting with adrenal failure during early infancy.Method: Consecutive cases with adren...

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: Maturity-onset diabetes of the young type 2 (MODY2) is an autosomal dominant inherited disease caused by heterozygous inactivating mutations in the glucokinase (GCK) gene. It mostly presents with mild fasting hyperglycaemia. MODY2 accounts for 2%–5% of all diabetes cases. It is treated with diet only, and complications are extremely rare. We presented here a family with MODY2 caused by a novel heterozygous p.E51*(c.151.G>T) mutation of the GCK gene.<p ...

Introduction: There is a growing interest in the relationship between obesity and renal damage. Chronic kidney disease is accepted as an important complication of obesity in adulthood. However, information on association between childhood obesity and renal functions is limited. In this study, It is aimed to investigate the renal functions in obese children and adolescents.Patients and methods: We enrolled 107 obese children and adolescents as a study gro...

Objective: Transsphenoidal surgery (TSS) is a treatment of choice for Cushing&grave;s disease (CD), whose effectiveness range is from 70 to 90%. Recurrence rate after successful treatment is about 25%. Preoperative predictors of remission and recurrence are still unexplored what leads to further investigations.Aim: Analysis of remission and recurrence rates of CD after radical treatment according to preoperative MRI....

Objective: Somatic mutations in the USP8 gene were discovered as the most common genetic defects in corticotropinomas with a frequency of 30 to 60% in adult patients. With regard to pediatric patients, establishing prevalence of USP8 mutations is still challenging due to the rarity of CD incidence in childhood.Aim: To determine the frequency of somatic genetic drivers of CD in a cohort of pediatric patients.<p class=...
