Background: Several studies have investigated the effects of GH replacement therapy (GHRT) on thyroid function in children with GH deficiency (GHD) leading to contrasting results. Indeed, GHRT has been reported to affect the peripheral metabolism of thyroid hormones, to alter TSH secretion by pituitary and to unmask secondary hypothyroidism.Objective and hypotheses: To evaluate long-term effects of GHRT on thyroid function in a large cohort of GHD childr...

Background: Hypoglycaemia is the most common and threatening complication in diabetic children. Nocturnal hypoglycaemia is mostly unrecognised and asymptomatic, but recurrent mild hypoglycaemia at night can lead to hypoglycaemia unawareness and reduced performance at daytime.Aims: To evaluate frequency and duration of nocturnal hypoglycaemia in type 1 diabetic children and to identify risk factors for such events.Patients/methods: ...

Background: Klinefelter syndrome is the most common sex chromosome disorder (prevalence: 1/600 newborn males), characterized by at least one extra X chromosome. If the diagnosis is not made prenatally, the disorder can remain unknown until pubertal or adult age. Kabuki syndrome, instead, is a rare, dysmorphic syndrome (1:32 000 newborn) characterized by distinctive facial features, multiple anomalies, and mental retardation. About 50–80% of cases are due to de novo</e...

Background: Pituicytoma is a very low-grade glioma that originate in the neurohypophisis and infundibulum.Objective and hypotheses: Describe diagnosis and treatment of associated pituicytoma and ACTH-secreting adenoma in a 6-year-old girl.Method: Case report and literature review.Results: We report the case of a 6-year-old presented with growth failure and associated weight gain, premature pubarche, and hyper...

Background: The incidence of childhood T1DM is rising worldwide. The incidence varies based upon geography, age, gender, genetic susceptibility, ethnicity, environmental risk factors or differences in features and quality registers, ranging from 0.1 to 65 per 100 000 children younger than the age of 15 years. In Spain, the incidence is high (20.6) but fluctuates among Autonomous Communities.Objective and hypotheses: Study the epidemiological data in pati...

Background: Patients who had undergone hematopoietic stem cell transplantation (HSCT) during childhood have been reported to have a higher risk of early metabolic syndrome (MS) and diabetes mellitus (DM) with a consequent increased risk of cardiovascular disease. Previous studies reported a cumulative incidence of abnormal glucose tolerance of 11.6% at 5 years from HSCT and of 69.3% at 10 years and a prevalence of MS of 32% at 4 years from HSCT.Objective...

Background: An association between type 1 diabetes mellitus (T1DM) and idiopathic generalized epilepsy is reported. Some authors suggest an autoimmune mechanism mediated by antibodies to glutamic-acid-decarboxylase (GAD), that is an enzyme involved in the synthesis of the neurotransmitter GABA. Dravet syndrome (DS) is a rare, severe epilepsy disorder characterized by febrile hemiclonic seizures or generalized status epilepticus starting at 6 months of age. In classical DS, a d...

Background: Noonan syndrome (NS) is an autosomal dominant disorder characterized by specific features including short stature, distinctive facial dysmorphic features, congenital heart defects, hypertrophic cardiomyopathy, skeletal anomalies and webbing of the neck. Molecular screening has shown that the majority of individuals with NS have a mutation in the PTPN11 gene. Noonan syndrome children may show an impaired GH/IGF axis. Moreover, recombinant human GH (rhGH) has been sh...

Background: Thyroid disorders (subclinical hypothyroidism and structural abnormalities) are common in Williams syndrome (WS) patients.Objective and hypotheses: Central hypothyroidism and GH deficiency (GHD) in a WS patient are discussed.Method: Case report and literature review.Results: A 5-month-old male was admitted to our hospital because of growth failure since the 3rd month, mild dysmorphisms, micropenis...

Background: Turner syndrome (TS) involves a partial or complete loss of an X chromosome. TS patients have an increased susceptibility to various disorders.Objective and hypotheses: To describe the clinical presentation, genotype and follow-up of TS patients controlled in the Pediatric endocrinology department of our hospital.Method: Retrospective study of patients diagnosed with TS at the ‘Navarra Hospital’ between 1980&#...
