Objectives: To demographic, socio-economic and social changes in the population of children who debuted in this century with DM type 1aPatients and Methods: Study patients with Type 1 Diabetes Mellitus from January 2000 to the present. Longitudinal study of global epidemiological, social, demographic and clinical variables and by five-year periods, focusing on the latte at Basque CountryRes...

Background: Congenital hyperinsulinism (CHI) is the most common cause of neonatal persistent hypoglycaemia. Current treatment lacks efficiency, and so are methods for differential diagnosis of diffuse and focal histological forms. Novel diagnostic and treatment approaches with the use of another hormone – glucagon-like-peptide-1 (GLP-1) – have been developed. GLP-1 is one of the key factors for maintaining euglycaemia. It stimulates insulin secretion...

Introduction: NR5A1 (nuclear receptor subfamily 5 group A member 1) is a transcriptional regulator of adrenal and gonadal development and function. Heterozygous and homozygous NR5A1 mutations have been described in 46,XY disorders of sex development (DSD). The clinical, endocrine and genetic features of three 46,XY children from two unrelated families (A and B) with NR5A1 genetic variants are reported.P...

Background: Congenital hyperinsulinism (CHI) is a heterogeneous group of disorders, characterized by hypoglycemia due to inappropriate insulin secretion. Despite huge progress in understanding the pathophysiology of CHI, its etiology remains unknown in about 30% of cases.Aim: To perform whole-exome sequencing in patients with CHI.Results: A total of 314 patients with congenital hyp...

Background: Adrenocortical Tumors (ACT) is a rare endocrine malignancy with heterogeneous presentation.Aim: To evaluate the clinical, biochemical and pathologic characteristics of pediatric ACT in a single tertiary center.Subjects and methods: Review of 28 medical records with childhood ACT (chronological age (CA) <18 years (y) treated between 1987 and 2017. Clinical, biochemical, and histological features (Wieneke index), stag...

Background: Sotos syndrome is characterized by overgrowth. The four mayor criteria for diagnosis are: overgrowth (accelerated bone age), macrocephaly, characteristic facial features and developmental delay. They can also present escoliosis, heart or genitourinary disease, seizures, hypotonia, cerebral malformations, feeding difficulties, hearing loss and a greater risk of tumours.Case report: A 10 months old girl was referred for overgrowth. BW and BL wa...

Background: Nail-Patella syndrome (NPS) or hereditary onycho-osteodysplasia (OMIM: 161200) is an autosomal dominant disorder characterized by nail and elbow dysplasia, patellar aplasia or hypoplasia, nephropathy and intra-ocular hypertension. The diagnosis confirmes by pathogenic variant in the LMX1B gene. There are reports of short stature in patients with this syndrome, however, data of the use of somatropin have not been presented. We describe the ...

Introduction: Prader-Willi Syndrome (PWS) is a complex genetic condition associated with feeding difficulties, hypotonia, developmental delay in infancy; hyperphagia leading to extreme obesity, growth failure and behavioral problems in childhood. Coeliac disease (CD), is an autoimmune disease characterized by gluten intolerance and a variety of symptoms most commonly diarrhea or constipation and failure to thrive. In PWS the challenge is to optimize growth while avoiding obesi...

Background: Anti-Müllerian hormone (AMH) inhibits the in utero growth of the Müllerian structures in female fetuses. In neonates with suspected disorders of sexual development (DSDs), the presence of testicular tissues and functioning Sertoli cells can be investigated by testing for serum AMH concentration.Objective: To evaluate the performance of two new AMH assays in a hospital laboratory.Method: The technical performan...

Background: Anti-Müllerian hormone (AMH) is produced by granulosa cells in small follicles prior to gonadotropin dependent growth and serum levels reflect the number of small antral follicles. There are currently no longitudinal data of individual AMH levels from infancy to adolescence.Aim: To evaluate whether AMH in infancy and childhood is associated with AMH levels and ovarian morphology peripubertal and in adole...
