Background: Disorders of sex development (DSD) are a heterogeneous group of disorders related to sex determination and differentiation. Although several genetic abnormalities have been discovered through genetic analyses, the underlying genetic causes of 30–40% of the 46,XY DSD cases are not yet known.Aim: To identify genetic defects in patients with 46,XY DSD.Material and methods: Seventy-six patients with 46,XY DSD were stud...

Background: Graves disease is the most common cause of hyperthyroidism in children. The frequency of the disease increases with age, peaking during adolescence.Thyroid storm is a rare but critical, ilness that can lead to multiorgan failure and carries a high death rate. Antithyroid drugs are usually recommended as the initial treatment and are generally well tolerated. Although current treatment options include radioactive iodine, but long term complications of thyroid irradi...

Background: Type 1 diabetes (T1D) is characterized by chronic hyperglycemia and microvascular complications like retinopathy, nephropathy, and neuropathy in long term. Nailfold video capillaroscopy (NVC) is a non-invasive method used to examine the microcirculation in the skin. In this study, we aimed to evaluate the microvascular structure in T1D with NVC, observe capillaroscopic alterations, and reveal the relationship of capillaroscopic abnormalities with g...

The melanocortin-4 receptor (MC4R) pathway is critical for the regulation of hunger, energy balance, and weight regulation. Individuals who carry variants in MC4R pathway genes may present with early-onset severe obesity and hyperphagia. Historically, genetic testing in individuals with severe obesity has been limited. The Rare Obesity Advanced Diagnosis™ genetic testing program aims to enhance access to genetic testing for European individuals with suspected rare geneti...

Key words: Dysgerminoma, gonadoblastoma, virilizationIntroduction: Gonadoblastoma is a rare ovarian tumor composed of sex cord cells and primitive germ cells. Although it is frequently seen in patients with 46,XY gonadal dysgenesis, it is also rarely seen in patients with a 46,XX karyotype. Here, we report a girl with a 46,XX karyotype presenting due to an uncommon cause of virilization, which was caused by bilateral gon...

Thyroid Function in Children with Prader-Willi Syndrome, the First 12 Months of GH Therapy

Musthaffa Yassmin M , Hughes Ian P , Harris Mark , Leong Gary

Background: Normal thyroid function is necessary for the optimal growth promoting effects of GH. Changes in the hypothalamic-pituitary-thyroid (HPT) axis following GH have been reported in subjects initially thought to be euthyroid. A specific group of patients, children with Prader-Willi syndrome (PWS), are thought to have a ‘vulnerable’ HPT axis.Objective and hypotheses: To evaluate the impact of paediatric GH therapy on thyroid hormone statu...

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 ...

Background: Pancreas transcription factor-1 alpha (PTF1A), encoded by the PTF1A gene, is a beta helix loop(bHLH) protein which involved in the development of the pancreas and cerebellar neurogenesis. Although mutations of PTF1A cause permanent neonatal diabetes(PNDM), pancreas agenesis and cerebellar agenesis, PTF1A enhancer mutations reported causing PNDM and isolated pancreas agenesis. In the present study, we evaluate the phenotyp...
