Introduction: Noonan syndrome (NS) is caused by mutations in RAS/MAPK signaling pathway genes. About 70% of the NS patients have short stature, and human recombinant growth hormone (rhGH) is an established yet not fully standardized treatment.Objective: To assess the first 2 years rhGH treatment effectiveness in NS patients at a single centre.Materials and methods: A total of 20 (16 male) NS patien...

Background: Genetic defects in the insulin receptor (INSR) are rare. Precise prevalence is unknown and significant clinical heterogeneity exists. Over 120 allelic variants have been described to date, spread throughout the receptor, and few geographical founder effects have been described. In this case series we identify a novel missense mutation in the tyrosine kinase domain of the INSR in three independently ascertained Irish families.Objective and Hyp...

Background: rhGH therapy may improve linear growth in children with inflammatory bowel disease (IBD). Poor bone health and abnormal body composition are recognised complications in paediatric IBD.Objective and hypotheses: To investigate the effects of rhGH on bone health and body composition.Method: Sub-analysis of 13 children with IBD (12CD; 1UC) in a randomized controlled trial. Either rhGH (0.067 mg/kg per day) as daily s.c. inj...

Background: In contrast to hypoglycaemia due to congenital hyperinsulinism, there are patients with a similar metabolic profile of hypoketotic hypoglycaemia, but low insulin levels and relatively low glucose requirements to maintain euglycaemia. So far, four patients with activating mutations in the insulin signal-transducing kinase AKT2 have been described, each also showing a syndromic phenotype including hemihypertrophy.Objective and hypotheses: We pr...

Background: Although the clinical presentations of congenital adrenal hyperplasia (CAH) have been studied in Saudi children, the literature review revealed no molecular report of 21-hydroxylase was published.Objective and hypotheses: The aim of this study was to determine the pattern of CYP21A2 gene-mutations of CAH in Saudi children.Method: Between January 2011 and March 2014 at King Fahad Military Complex, Dhahran, Saudi Arabia, ...

From time to time pediatric endocrinologists may be confronted with paradoxical constellations. Here, we report on a 13-year-old boy with type-1 diabetes. He had polyuria and polydipsia for the previous 2 weeks. Three days before presentation, he got increasingly exhausted and developed recurrent vomiting. At presentation his weight was 41,4 kg (P 25-50) and his height was 154 cm (P 25-50). Initial labs were HbA1c 10.2%, glucose 530 mg/dl, pH 7.15, base excess - 21.1 mmol/l, b...

The girl was born full-term vaginally with birth weight 3.380kg. She had stayed in neonatal unit for 3 days for neonatal fever. Physical examination was unremarkable. She had normal-looking female external genitalia. She was discharged after a negative infection screen.She presented again at the age of 11 years with hoarseness of voice. Physical examination revealed normal growth and blood pressure. She had hoarseness of voice with mild laryngeal promine...

Background: GnRHa (gonadotropin releasing hormone analogue) inhibits growth spurt during treatment of precocious puberty. So they have limitation of final height gain.Objective and hypotheses: It is need to study about what factor associated with growth decrement and ideal suppression level of sex steroid during GnRHa treatment.Method: Female Sprague–Dawley rats of 3 weeks of age (Total 15) were divided into three groups; (1) ...

Background: Diabetes mellitus (DM) in childhood was mostly type 1 DM (T1DM), but sometimes it is not easy to classify, especially in the case having both type 2 clinical phenotype and autoantibody positivity. It is named as latent autoimmune diabetes in youth or type 1.5 DM (T1.5DM).Objective and hypotheses: This study was designed to evaluate the clinical characteristics of T1.5DM who had autoantibody positivity with clinical phenotype of T2DM.<p cl...

Purpose: Aetiologies of congenital hypothyroidism (CH) in newborn period are various, and TSH receptor (TSHR) mutation is known as one of them. We evaluated mutational analysis of the gene TSHR and clinical characteristics in the patients with CH or neonatal hyperthyrotropinemia.Method: Mutation analysis was done in 96 children with CH or transient hyperthyrotropinemia who has been managed at the Department of Pediatrics in Dankook University Hospital.
