Background: Neonatal diabetes (ND) is a rare condition (1:160.000-260.000 live births) associated with diabetes onset within the first 6 months of life. It can be permanent (PNDM) or transient (TNDM), and several genes can be implicated in both, namely KCNJ11. Clinical phenotypes usually correlate to the causal gene. KCNJ11 mutations are usually associated with PNDM whilst the most frequent cause of TNDM is disordered imprinting in the 6q24 locus.Objecti...

Background: Mixed gonadal dysgenesis is most commonly associated with 45,XO/46,XY karyotype.Objective and hypotheses: We report three cases that illustrate the genotype and phenotype variability of mixed gonadal dysgenesis.Methods: Data was extracted from Pediatric Endocrinology charts in a tertiary care centre after consenting the parents.Results: i) A 13 year old patient, 45,XO/46,X, isodicentric Y chromoso...

Background: Ovotesticular disorders of sexual development (DSD) are a rare form of DSD with co-existence of both ovarian and testicular tissue in one or both gonads.Case report: A term infant (weight +1.38 SDS) presented at birth with severe penoscrotal hypospadias, a small phallus and a right hemiscrotum with descended gonad (external masculinization score 1.5). Pelvic ultrasound revealed no Mullerian structures, a small right gonad with probable epidid...

Background: Secondary pseudohypoaldosteronism presents with hyponatremia and hyperkalemia due to a transient aldosterone resistance.Objective and hypotheses: We recommend a check of urea and electrolytes in all infants with urinary tract infection, dehydration and failure to thrive.Method: A 5 month old presented with a day’s history of poor feeding and two episodes of vomiting. He was afebrile with normal observations. His ur...

Background: We presented 20-year follow-up of two patients with 11β- hydroxylase deficiency, one of them has novel mutation.Case 1: The male patient was diagnosed at the age of 9-months. He presented with penil growth and pubic hair. At diagnosis blood pressure was normal, his hormonal profile was distinctive of 11β-OHD, with elevated serum levels of 11-deoxycortisol (DOC 134 ng/ml, N: 0–1.18). Hydrocortisone was introduced immediately aft...

Background: Diabetes mellitus is not characteristic of Beckwith Wiedeman Syndrome (BWS). If anything, BWS is associated with hypoglycaemia secondary to hyperinsulinaemia. A case of permanent neonatal diabetes mellitus and BWS have never been reported from our setting.Objective and hypotheses: To report on a 17 years old boy with BWS diagnosed with permanent neonatal diabetes mellitus at 4 months of age and to determine the molecular genetics study which ...

Background: Disorders of sex development (DSD) can be caused by many hormonal and genetic defects. One rare condition is a mutation of the SRY-gene disturbing normal sex differentiation. Identical twins with this disorder of varying degree are presented to learn how difficult social sex assignment may be in such a case.Case presentation: Identical 46, XY twins were born in 1985 from non consanguineous, healthy parents of German origin. T...

Introduction: McCune–Albright syndrome (MAS) is a rare disease defined by café-au-lait spots, gonadotropin-precocious puberty and fibrous dysplasia. It could be associated with others endocrinopathies: thyroid involvement as a common feature. The prevalence is very low, being outstanding the neonatal diagnosis, especially in males.Case presentation: A male term newborn with a café-au-lait extensive spot involving the back, arms, legs and s...

Background: Congenital combined pituitary hormone deficiency (CPHD) may be associated with pituitary/extra pituitary abnormalities. Well-known causes are mutations in pituitary transcription factor genes. Agenesis of internal carotid artery (ICA) is a rare vascular anomaly that has been associated with CPHD.Case presentation: The patient is a 2-year old male, born at term to non-consanguineous parents, birth wt 3.2 kg, length 47 cm, no gestational or per...

Background: Pre-pubertal gynecomastia is characterized by the presence of palpable breast tissue in boys in the absence of signs of sexual maturation. Gynecomastia is common in normal males in the neonatal period, at early puberty, and with increasing age and pre-pubertal gynecomastia is a rare condition and can be associated with excessive aromatase activity or oestrogen-producing adrenal or testicular tumours.Case Presentation: A 3-year-old presented w...
