Mosaic variegated aneuploidy (MVA) syndrome represents a rare autosomal recessive disease characterized by aneuploidies with gain and loss of multiple chromosomes. We describe case of two Moroccan brothers with MVA2, due to CEP57 mutations. Patients are 17 and 13-year-old male siblings of a Moroccan healthy consanguineous couple. Oldest brother was delivered at 35 gestational weeks after IGR diagnosis, small for gestational age (SGA, 1300 grams, -3 SDS). Younger patient’...

Six-year-old female, diagnosed with GH deficiency at another Center (H: -3.13SDS; H peak with clonidine 5.7ng/mL, with insulin 1.2ng/mL). Brain MRI at diagnosis: small pituitary gland, ectopic neurohypophysis, normal stalk, right internal carotid artery aplasia. At 10 years onset of polyuria-polydipsia syndrome (PPS) (4L/day–154ml/kg/die); mood disorders and ADHD diagnosis were also reported. A fluid deprivation test was performed, lasting 22 hours (pre: S-Osm 275mOsm/L,...

We investigated the efficacy of bariatric surgery in two patients with craniopharyngioma-related hypothalamic obesity during 18 months of follow-up. Patient n1, diagnosed with craniopharyngioma and treated with complete surgical excision ...

A 5-years-old boy was admitted because of polydipsia and polyuria. His family history was unremarkable. After water deprivation test (10h), laboratory test showed high levels of serum sodium (150.1 mmol/L), low urine osmolarity (88 mOsm/kg) and high serum osmolarity (301 mOsm/kg) consistent with the diagnosis of central diabetes insipidus (CDI). He started therapy with oral desmopressin with clinical improvement. Brain MRI revealed pituitary stalk thickening (3 mm), no hyperin...
