Use of [F]fluorocholine PET/CT in the detection of primary hyperparathyroidism in paediatrics: a case report.

Objectives: The most common cause of primary hyperparathyroidism (PPH) in children is a parathyroid adenoma. Among this population, PPH exhibits higher levels of morbidity, severity and target organ involvement compared to adults. When there is suspicion of PPH, cervical ultrasound and Tc-sestamibi SPECT/CT are the imaging test traditionally indicated.

Mutations in PMM2 gene in four unrelated Spanish families with polycystic kidney disease and hyperinsulinemic hypoglycemia.

Objectives Hyperinsulinemic hypoglucemia (HH) is characterized by a dysregulation of insulin secretion from pancreatic β cells. Congenital hyperinsulinism has been associated with specific genes in monogenic forms and also with other diseases with a yet unknown genetic cause. In 2017, Rubio Cabezas et al.

A de novo CACNA1D missense mutation in a patient with congenital hyperinsulinism, primary hyperaldosteronism and hypotonia.

Congenital hyperinsulinemic hypoglycemia is the most frequent cause of persistent and recurrent hypoglycemia in the first years of life and in many patients rare genetic variants can be identified. Recently a case of congenital hyperinsulinemic hypoglycemia and a severe neurodevelopmental syndrome due to a mutation in the voltage-gated Cav1.3 Ca channel gene has been reported which required long-term treatment with diazoxide.

Endocrinological late effects of oncologic treatment on survivors of medulloblastoma.

Introduction: Radiation therapy, chemotherapy, and surgery used to treat brain tumors have effects on the hy pothalamic-pituitary-adrenal axis and can result in endocrine dysfunction in up to 96% of cases.

Patients And Method: Retrospective and descriptive study in patients diagnosed with medulloblasto ma who underwent treatment with chemo and radiotherapy in the last 20 years in a tertiary hospital. The variables analyzed were age, sex, weight, height, body mass index (BMI) at the end of follow-up, sexual maturity stage, serum levels of TSH and free T4, ACTH/cortisol and IGF-1, FSH, LH, estradiol, testosterone, lipid profile (total cholesterol), and growth hormone dynamic function test.

A Novel Mutation of in a Patient with Schaaf-Yang Syndrome and Hypopituitarism.

Introduction: Schaaf-Yang syndrome (SYS) is caused by truncating point mutations of the paternal allele of , an imprinted gene located in the critical region of Prader-Willi syndrome (PWS). These patients present a phenotype with neurodevelopmental delay, hypotonia, joint contractures, and a particularly high prevalence of autism (up to 75% in affected individuals). The loss of function of is suggested to contribute to endocrine hypothalamic dysfunction in individuals with PWS.
