Background: Persistent Müllerian duct syndrome (PMDS) is a Disorder of Sex Development (DSD) caused by mutations in genes encoding anti-Müllerian hormone (AMH) or its type II receptor (AMHR2) with autosomal recessive transmission. Objective: To report a case of transverse testicular ectopia (TTE), associated with PMDS, initially presented as an obstructed inguinal hernia.Case presentation: An 18- days- old male infant, wi...

Introduction: The metabolically healthy obese phenotype (MHOF) defines obese patients who have preserved insulin sensitivity and who do not have metabolic complications: lower risk of cardiovascular disease and type 2 diabetes in adulthood. Recent studies indicate that TMI (kg/m3) estimates the percentage of body fat more accurately than the BMI and it has been proposed to substitute the use of the BMI z-score values by those of the TMI. TMI values ...

Background: Subcutaneous calcification is a rare clinical symptom in infancy. Progressive evolution and association with brachydactyly could be indicators of Albright hereditary osteodystrophy (AHO). In clinical practice, AHO is difficult to diagnose because of clinical heterogeneity. Typical features of AHO without any evidence of hormone resistance are termed pseudopseudohypoparathyroidism (PPHP; OMIM 612463).Case report: Male patient referred to study...

Introduction: Leydig cell tumors are rare (3% of testicular neoplasms). 80% of cases occurs in adult population, although a quarter is described in prepubertal patients older than four years. The clinic differs according to the patient's age. Activating mutations, acquired and limited to the tumor tissue, are described in exon 11 of the LH receptor gene. And in mixed Sertoli-Leydig tumors activating mutations of the Gs-alpha subunit of the stimulat...

Background: To evaluate the efficacy of thyroidectomy, it is necessary to know its complications; however, there is a great discrepancy in the literature regarding its incidence. A greater surgical aggressiveness achieves better control of the disease, but may be accompanied by more complications. Hypocalcemia is the most frequent potential complication after thyroidectomy, but its persistence can lead to serious systemic effects. The objective of this study i...

Objective: To study how basal metabolism influences the somatometric evolution of the child and adolescent population with obesity in a pediatric endocrinology clinic; multichannel impedance study, TANITA BF 430.Results: 100 randomly selected patients from a database with 1400 records were studied. Most of the patients who come to these consultations for obesity are girls, between 8 and 11 years old. The group of boys at...

X-linked hypophosphatemic rickets (XLH) is the most common form of hereditary rickets. It is caused by inactivating mutations in the PHEX gene (phosphate-regulating-endopeptidase-analog, X-linked), leading to increased fibroblastic growth (FGF-23) levels, responsible for the renal phosphate wasting. This results in hyperphosphaturia and hypophosphatemia, and altered bone mineralization, in the absence of vitamin D deficiency. Classical treatment consists on oral supplementatio...

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, ...

Introduction: Variegated mosaic aneuploidy syndrome (MVA) is a rare autosomal recessive disease characterized by a variable percentage of chromosomal gains and losses, resulting in multiple mosaic aneuploidies, which explains a great phenotypic variety and may predispose to the development of cancer. Bi-allelic mutations in CEP57 are the cause of MVA2. CEP57 encodes a centrosome protein involved in microtubule stabilization and is crucial for maintaining prope...

Background: Psychosocial factors and health events are important for patients with chronic diseases such type 1 diabetes (TD1).Objective and hypotheses: The aim was to explore the psychosocial factors, health events and comorbidity found at diagnosis and during the follow up of children and adolescents with type 1 diabetes. Also to analyze the association between socioeconomic status and glycaemic control.Method: Medical charts of ...
