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&#...

Introduction: Primary hyperparathyroidism (PHPT), often caused by a single adenoma (80%–85%) or hyperplasia or adenomas involving multiple glands, is the major cause of hypercalcemia. PHPT is common and occurs in individuals of all ages, but its prevalence is lower in young adults. Parathyroid tumors and PHPT can be caused by germline (hereditary PHPT) or somatic mutations of tumor suppressor genes (e.g., multiple endocrine neoplasia type 1 and CDC73) and...

IMNEPD is a mitochondrial disease caused by homozygous mutations in the PTRH2 gene, a nuclear gene coding for a primary mitochondrial protein. IMNEPD was first described in 2014. So far only 3 other case reports have been published, reporting on a total of 15 patients. We report on two affected siblings of whom the girl developed an antibody negative diabetes at 13 years of age with typical symptoms (polyuria, polydipsia, weight loss of 1,5 kg), and without diabetic k...

The incidence of TIDM varies greatly between different countries and regions. In Navarre, located in the north of Spain, at the western end of the Pyrenees, there has been a clear increase in the incidence of TIDM, from 13,5 cases per 100000 in the decade 1990-2000 to 20,1 cases per 100000 between 2006-2011. We wonder if this upward trend has continued in recent years. Our hospital is a reference center for Pediatric Endocrinology in Navarre.Obje...

Background: Carbohydrate counting is essential in diabetes management to match insulin doses to carbohydrate intake. Though recommendations concerning macronutritient composition exist (ISPAD Clinical Practice Consensus Guidelines 2022: Nutritional management in children and adolescents with diabetes), fat and protein intake is usually not calculated. Therefore, little is known if these recommendations are followed. Lower carbohydrate intake is reported to be ...

Aim: to assess and follow-up neck circumference and its relationship with a metabolic score in patients with abdominal obesity after a lifestyle intervention.Patients, Material and Methods: 122 children and adolescents with abdominal obesity, aged 7 to 16 years, were included in a control randomized intervention study (NCT031472). Abdominal obesity was diagnosed using the waist circumference. The intervention included an...

Background: GH deficiency remains the main indication for GH therapy in children. GH therapy has subsequently been approved in the USA and Europe for other conditions resulting in short stature, including Turner Syndrome, being born small for gestational age with failure to attain normal growth, Prader-Willi Syndrome, chronic renal insufficiency, short stature homeobox-containing gene deficiency, and in the USA exclusively Noonan Syndrome and idiopathic short ...
