Hyperinsulinism is a common cause of severe and persistent hypoglycaemia during the neonatal period. Eleven genes have been identified that lead to unregulated insulin secretion and hyperinsulinemic hypoglycaemia (HH). Inactivating mutations in UCP2 gene have been described in a very small number of patients with HH. UCP2 protein is an inner mitochondrial carrier protein and its loss of function causes enhanced glucose oxidation and increased intracellular ATP synthes...

Hyperinsulinemic hypoglycaemia (HH) is a common cause of severe and persistent hypoglycaemia during the neonatal period. Risk factors for neonatal transient hyperinsulinism are small-for-gestational age (SGA), perinatal asphyxia and maternal diabetes mellitus. This state of hyperinsulinism in SGA newborns could persist from weeks to years, resulting in an important comorbidity; its pathogenesis remains unknown.Objective: To describe the clinical-genetic ...

Background: Pheochromocytoma is an uncommon tumor, producer of Catecholamines and causing hypertension in childhood. It is associated to genetic alterations, generally related with RET gene disorders.Method: We present the case of a unilateral familial isolated pheochromocytoma, present in father and son, carriers of a heterozygous mutation in the VHL gene (c.235C > G; p.R79G).Case: Male, 9 years-old with history of fever, prof...

Background: Permanent neonatal diabetes (PND)with heterozygous mutations of KCNJ11, respond to treatment with sulphonylureas. We report a case of PND in a baby, and mother previously mis-diagnosed with Type 1 DM. Both were switched from insulin to oral sulphonylureas. We evaluate the response and evolution.Case report: A male newborn at 37 weeks’ gestation, with a birthweight 2750 g (40thC) and length 48 cm (40thC), was admitte...

Background: Fatty liver disease is diagnosed increasingly in obese children, which pathophysiology remains unexplained. Risk factors as insulin resistance, evolution of steatosis and hypertriglyceridemia, should be taken into consideration in its development.Objective and hypotheses: To analyse the prevalence of hepatic steatosis identified by ultrasound, as well as features and anthropometric data in our population divided into 2 groups: with steatosis ...

Background: Hepatic steatosis is common in obese children. The pathophysiology remains unexplained but it is known that insulin resistance and hypertrilycerdemia are involved in its development.Objective and hypotheses: To analyse the prevalence of hepatic steatosis identified by ultrasound, as well as features and anthropometric data in our population divided into two groups: (with steatosis and without steatosis) to assess the risk factors.<p class...

Introduction: Pilocytic astrocytoma is the most common type of CNS astrocytoma in children. Clinical manifestations depend on its location and size and initial symptoms are usually related to neurological deficits or signs and symptoms of intracranial hypertension. Involvement of the hypothalamic area, pituitary infundibulum and leptomeningeal spread are exceptional. The case of a patient with central precocious puberty in whom the initial neuroimaging study oriented the diagn...

Background: Gene SHOX haploinsufficiency due to deletions or mutations in heterozygosis causes a wide spectrum of phenotypes ranging from very severe disharmonic short stature (S. Léri-Weil, S. Turner) to very mild forms with the appearance of idiopathic short stature (IST) of difficult clinical recognition. Auxological study directed at evaluating body disproportions such as the sitting height/height (SH/H) ratio in patients with IST has been postulated as usefu...

Background: Hypochondroplasia is an osteochondrodysplasia inherited in an autosomal dominant pattern that results in a disproportionately short stature, characteristic facial features and skeletal alterations such as lordosis and genu valgum. Haploinsufficiency of the fibroblast growth factor receptor 3 gene (FGFR3) is responsible for 50–70% of the cases, but a negative result doesn’t rule it out.Case presentation: We report a...

Introduction: Pituitary gigantism is caused by a somatotroph pituitary tumor that occurs before epiphyseal closure and is associated with increased morbidity due to the systemic effects of chronic hormonal excess. It is an extremely rare disease, with an estimated incidence of 8 per million person-years. Therapeutic modalities for pituitary gigantism are the same as those for acromegaly and include surgery, medication and radiation. Medical treatment plays an ...
