Background: Vitamin D adequate concentration is essential for growth, development and health during vital cycle. Hypovitaminosis D pandemic is associated with a wide range of pathologies.Objective and hypotheses: The objectives of the present study were to characterize vitamin D status in children and adolescents residing in Galicia (Northwest of Spain, latitude 43°N) and to determine if serum 25-hydroxy-vitamin D (25(OH)D) concentration is related ...

Introduction: Obesity is the most common nutritional disorder in the paediatric age. Decreased physical activity and increased inactivity are important factors that are involved in this pandemic. The highest prevalence of obesity in Europe is in the South.Objective: To study the relationship between the practice of a regulated sport and lipid profile in overweight children and adolescents.Material and methods: 318 overweight childr...

Introduction: The identification of obese patients with increased susceptibility and risk for glucose intolerance and type 2 diabetes requires an oral glucose tolerance test (OGTT). Reference values for Body mass index (BMI) and Tri-Ponderal mass index (TMI) according to age and sex of healthy children in Spain without malnutrition or obesity have recently been published (*). TMI values remain very uniform in both boys and girls from the age of 8 to 18 years, ...

Turner Syndrome (TS) is a relatively common chromosomopathy and according to epidemiological studies the prevalence of Autoimmune thyroiditis (AIT) in TS fluctuates from 10% to 21% versus 1.3% in the general population.Objective: – to retrospectively evaluate thyroid autoimmune disorders and thyroid function in a group of 93 TS patients.– to compare the prevalence of AIT and thyroid dysfunction in subgroups of TS accordin...

Background: Gonadotropin-releasing hormone analog (GnRHa) is the gold standard treatment for central precocious puberty (CPP). In recent years, increased prevalence of polycystic ovary syndrome (PCOS) has been reported in girls treated with GnRHa for CPP. Attributes of PCOS overlap normal pubertal changes, making the diagnosis of PCOS during adolescence controversial.Aim: To assess the metabolic profile, the prevalence of PCOS and describe its phenotypes...

Background: Rasopathies are a heterogeneous group of diseases that share phenotypic characteristics such as facial dysmorphism, congenital heart disease and short stature.Objective and hypotheses: Evaluation of growth and study of the GH–IGF1 axis. Molecular Study of the PTPN11, SOS1, RAF, KRAS, NRAS, MAP2K1 and MAP2K2 genes. Evaluation of growth and study of the GH–IGF1 axis.Method: Descriptive retrospective study in pat...

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: The 12q14.3q15 microdeletion syndrome is a rare entity of which only 16 new cases have been described to date. The syndrome consists of the association of severe pre- and postnatal growth retardation, proportional short stature, psychomotor retardation and osteopoikilosis. The phenotypic appearance of these patients poses a differential diagnosis with Silver-Russell syndrome, among other entities.Clinical description: A 10-month-old boy was r...

Background: Patients with Klinefelter syndrome (SK) have a 47, XXY karyotype and tall stature as a result of overexpression of the SHOX gene. The case of a patient with peculiar phenotype, microcephaly, proportional short stature and 47, XXY karyotype with a deletion in band p11.3 of one X chromosome is presented.Clinical description: A 2-year, 4 month-old boy was referred for study of growth retardation. The product of a first gestation of 39 weeks of h...

Introduction: Kabuki Syndrome (KS) is a rare genetic disorder characterised by dysmorphic facies, poor developmental growth, hypotonia, skeletal abnormalities, intellectual disability, as well as systemic malformations. The pathogenic or likely pathogenic variants of the KMT2D or KDM6A genes are responsible for about 70% of the cases, while the rest are diagnosed based on clinical features consistent with KS. This paper reviews the clinical features, genetic t...
