Background: Adrenocortical carcinoma (ADCC) is a rare cancer in children and differs significantly in epidemiology, clinical characteristics, and biologic features from their counterparts in adults. Germline mutations of the TP53 tumor suppressor gene are associated with cancer predisposition in families with the Li-Fraumeni syndrome.Aim: To report a young girl with family a history of ADCC who presented with severe virilisation secondary to ADC...

Allgrove’s or ‘4A syndrome’ is a rare autosomal recessive multisystem disorder characterised by adrenocorticotropin hormone resistant adrenal insufficiency,alacrima ,achalasia and neurological abnormalities. The disease-causing gene (AAAS) encodes a protein of 546 amino acids called ‘aladin’ (for alacrima-achalasia-adrenal insufficiency-neurologic disorder). We report two siblings and three cousins suffering from Allgrove syndrome in a Turkish family. ...

Background: 3β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of congenital adrenal hyperplasia (CAH) and caused by loss of function mutations in the HSD3B2 gene. In classic form, affected patients have salt wasting early in infancy and may have ambiguous genitalia in both sexes. Herein we report a nonvirilized female patient with classic form of 3βHSD deficiency due to homozygous S218P mutation in the HSD3B2 gene and classic phenylketonuria....

Background: It has been reported that there is a relationship between circulating leptin and sex steroid hormones and leptin is able to stimulate estrogen secretion by increasing aromatase activity in adipose stromal cells and breast tissue. Leptin receptors have been also shown in mammary epitheleal cells and it has been suggested that leptin is involved in the control of the proliferation of both normal and malignant breast cells.Objective and hypothes...

Background: Patients with vitD resistant rickets (VDRR) due to vitD receptor (VDR) mutations have extreme rickets along with alopesia, severe hypocalcemia, hypophosfatemia secondary to hyperparathroidism and elevated 1,25(OH)2vitD. Although there is no standard therapy for this patients, long-term or intermittanat i.v. or high dose oral calcium suplementations are recommended to correct the hypocalcemia and secondary hyperparathyroidism. ...

Introduction: Growth hormone (hGH) and/or growth factors are thought to play a role in the pathogenesis of diabetic retinopathy. Increased treatment of human growth hormone (hGH) in children rise questions concerning the safety of GH replacement therapy on ophtalmic changes. Adverse effects of hGH treatment (pseudotumor cerebri, papilloedema, retinal changes mimicking diabetic retinopathy, neovascularization) have been reported in some papers. In this study, i...

Introduction: Congenital adrenal hyperplasia is an autosomal recessive disorder characterized by enzyme deficiencies in the adrenal steroidogenesis pathway. The most common type is 21 hydroxylase deficiency and is divided into two groups as classical and nonclassical type. 75% of the classical type of cases is salt-losing type, and cortisol and aldosterone deficiency symptoms occur in patients. Female cases presented with ambiguus genitalia due to hyperand...

Introduction: Graves' disease is the most common cause of hyperthyroidism in children with autoimmune thyroid disease. Clinically, goiter, tachycardia, restlessness, craniosinostosis, hyperactivity, growth retardation, diarrhea may occur.Graves' disease is rare under 4 years of age. Treatment options include antithyroid therapy, surgery, and radioiodine therapy. The most commonly used antithyroid therapy is methimazole and has serious side effects such...

Background: DEND syndrome is characterized by developmental delay, epilepsy, and neonatal diabetes mellitus (NDM) due to mutations in KCNJ11 and ABCC8 genes. Intermediate DEND (iDEND) syndrome is a rare mild form with mild motor, speech or cognitive delay and an absence of epilepsy. Improvement in glycemic control and neurologic symptoms has been reported in three cases with iDEND syndrome.Objective and hypotheses: To present the result...

Objective: The aim of this study was to evaluate demographic characteristics; clinical, laboratory, imaging features; and response to treatment of boys who were followed up and treated with the diagnosis of central precocious puberty (CPP) in Turkiye.Materials and Methods: The study was planned as a multicenter, retrospective study. Cases with a diagnosis of CPP, whose follow-up data were available were included. Patient...
