Background: The benefits of levothyroxine (L-T4) therapy in subjects with mild SH (TSH between 5 and 10 mU/l with normal FT4 values) are controversial. Current recommendations in adults suggest to start on treatment selected groups of subjects with mild SH and evidence of atherosclerotic CV disease. Data in children are lacking.Objective and hypotheses: To investigate the effect of L-T4 treat...

Of the 67 included DSD patients, 33% were HSCs. 68% women and 32% men, with a total concordance between legal sex, current gender and chromosomal sex. Median age: 10.5 years, IQR 8-14. The most frequent clinical form was non-classical (NC) 45.5%, followed by classical with saline loss (CPS) 41%. The distribution of each clinical form according to the karyotype is significant (P = 0.013), the most frequent with XY karyotype is CPS and in NC forms all cases are XX. Med...

Background: Disorders of sex development (DSD) due to mutations in the NR5A1 (SF1) gene result in a highly variable phenotype.Objective: To report the clinical phenotype and the molecular/structural characteristics of the gene-protein product arising from three novel mutations of the NR5A1 (SF1) gene found in patients presenting with 46,XY DSD.Method: Phenotype determined from interrogation of clinical case notes. Interpre...

Background: Experience with nasogastric administration of oral DDAVP [desamino-D-arginine-8-vasopressin] lyophilisate (ODL) for central diabetes insipidus (CDI) in disabled children with swallowing coordination difficulties is limited.Objective: We aimed to assess the safety and efficacy of nasogastric use of ODL in disabled children with CDI.Methods: Clinical, laboratory and neuro...

Introduction: Individuals with Prader-Willi syndrome (PWS) suffer from hyperphagia, hypotonia and hypothalamic dysfunction, leading to a variety of pituitary hormone deficiencies. Central adrenal insufficiency (CAI) has been reported in PWS, while each of these studies used different testing modalities and cut-off values. Therefore, reported prevalence of CAI ranges from 0% to 60%. It has been speculated that CAI might be responsible, at least in part,...

Background: Glucokinase (GCK) acts as the glucose sensor of β-islet cells, regulating insulin secretion in response to changing glucose concentrations. Homozygous GCK mutations are a rare cause of permanent neonatal diabetes. Heterozygous mutations lead to GCK MODY, causing mild hyperglycaemia, not usually requiring treatment.Case: The index case was born to consanguineous parents at 36+2 weeks gestation, weighing 1610 g (0.4th centile). Hy...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...

Background: The concurrence of transverse testicular ectopia (TTE) with persistent müllerian duct syndrome (PMDS) is extremely rare. Here, we report a case of TTE with PMDS in a 7-month-old male infant presenting with inguinal hernia and a novel homozygous mutation in the AMH gene. CASE REPORT: A 7-month-old male infant presented to pediatric surgery department with an inguinal hernia on the left side and bilateral undescended testis. During left herniotomy, tiss...

Background: McCune Albright syndrome (MAS) is defined by the classic triad of precocious puberty, fibrous dysplasia of bone and café au lait skin pigmentation. However, the clinical spectrum is often more variable due to mosaic distribution of the postzygotic GNAS-mutation. Hypercortisolism occurs in a minority (5%) of patients. It is most frequently caused by nodular adrenal hyperplasia and can be life-threatening. Decisions on whether clinical management should be conse...

Background: Mammary duct ectasia is a bening breast condition which affects primarily middle-aged to elderly women. However, it can occurs wherever there is breast ductal epithelium.Case presentation: A 9-years-old boy was referred to the regional paediatric endocrine clinic from the General Practicioner due to gynaecomastia. Pubic hair development started at the age of 8. Personal and family history were unremarkable except for a history of coping with ...
