Background: Donohue syndrome is a rare congenital syndrome of insulin-resistance and abnormal glucose homeostasis, caused by mutations in the insulin receptor (INSR) gene. It is characterized by specific phenotypic and clinical features and the diagnosis is based on clinical, biochemical and genetic criteria.Case reports: We report two siblings with Donohue syndrome with typical dysmorphic features and multiple clinical and biochemical characteristics. G...

Background: Bartter syndrome represents a rare severe condition, autosomal recessive, corresponding to several genes, characterized by an illness of the renal ascending branch of the handle of Henle. Only 15 cases of BSHPT have been communicated, either in publications or orally, but none presented such severe bone manifestation as ours.Objective and hypotheses: To present bone features of two patients suffering from severe BHSPT, so as the therapeutic a...

Background: There is limited information on the ability of demographic or lifestyle factors to predict short term changes in weight status during childhood.Objective and hypotheses: To study the effect of parental (educational level, BMI status and perception of child’s weight status) and childhood factors (eating habits, sedentary behaviour and physical activity), on 1-year BMI increments by the use of BMI, BMI SDS and BMI SDS conditional gain....

Background: A 6-week-old male was admitted for investigation of prolonged jaundice. The pregnancy was unremarkable with a normal at term delivery. The neonatal screening was unremarkable. The boy was born to consanguineous parents of Turkish descent.Objective and hypotheses: At presentation serum levels of thyrotropin, T4 and T3 were low and prolactin slightly elevated. Venous TSH was undetectable low. Central hypothyroidism was dia...

Background: Hereditary hypophosphatemic rickets (HR) is a group of rare diseases with disordered phosphate metabolism. The Norwegian cohort of HR patients has not previously been described.Objective and hypotheses: The aim of the study was to characterize the genotype, phenotype, and complications to treatment in a national cohort of Norwegian children HR.Method: For assessment of genotype, Sanger sequencing of PHEX, FGF23, DMP...

Background: Transient hypoparathyroidism is a recognised cause of hypocalcaemia during the neonatal period and difficult to differentiate from permanent forms.Objective and hypotheses: We present the challenges of monitoring and managing neonates with hypocalcaemia and inappropriately low PTH.Method: Cases 1 and 2 had congenital heart disease (CHD) but were FISH negative for 22q11 deletion. Both were treated with supplemental doses...

Background: Prolactinomas are relatively rare during childhood, with an incidence of 0.1 per million. Children with hyperprolactinaemia have widely varied presentations depending on age, sex, and tumour size. Whilst adults typically present with galactorrhoea or hypogonadism, children tend to present with pubertal delay and growth issues.Objective and hypotheses: Poorer surgical outcomes have been reported in children with macroprolactinomas compared to ...

Introduction: Primary adrenal insufficiency (PAI) is a potentially life-threatening condition that requires appropriate diagnosis and treatment. The most common cause of PAI is congenital adrenal hyperplasia (CAH), but other well-established aetiologies include metabolic and autoimmune disorders, and physical damage. Mutations in more than 30 genes have now been associated with PAI, with considerable biochemical and phenotypic overlap. It is therefore importan...

Pseudohypoparathyroidism (PHP) and related disorders lead to a wide spectrum of abnormal physical characteristics, neurocognitive and endocrine abnormalities. PHP (including all subtypes), pseudoPHP, acrodysostosis and progressive osseous heteroplasia refer to heterogeneous disorders characterized by physical findings, differently associated in each subtype, including short bones, short stature, stocky build, subcutaneous ectopic ossifications, as well as laboratory abnormalit...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...
