Introduction: Metabolic control (MC) of patients with type 1 diabetes (DM1) is linked with complications in short and long term follow up. Adolescence is a critical period in the treatment of DM1, making it difficult to achieve good MC. Few studies, all conducted in the United States, have shown an association between mother´s depressive symptoms with poorer MC of their adolescent.Objective: To evaluate the associat...

Introduction: Non-classical congenital adrenal hyperplasia is the most common pathological cause of early pubarche in prepubertal patients. However, this may also be the first manifestation of central precocious puberty or an androgen producing suprarrenal or ovarian tumor.Objective: To present a clinical case initially misdiagnosed as Congenital Adrenal Hyperplasia that turned out to be an Ovarian Tumor of Leydig Cells.Clinical ca...

Background: Fetal growth is partly regulated by epigenetic factors, such as DNA methylation. Altered methylation status in placental genes relates to gestational diabetes, preeclampsia and prematurity. However, the epigenetic mechanisms underlying fetal growth restraint in uncomplicated pregnancies remain unknown.Objective and hypotheses: We aimed at identifying new candidate genes related to fetal growth, by assessing DNA methylation profiling in placen...

Background: 17α-Hydroxylase/17,20-lyase deficiency is a rare form of congenital adrenal hyperplasia caused by mutations in CYP17A1, characterized by reduction of androgens, estrogens and cortisol production and mineralocorticoid excess.Objective and hypotheses: To describe the clinical and molecular characteristics of two sisters with 17α-hydroxylase/17, 20-lyase deficiency.Method: Two sisters, phenotypic females...

Background: Pituitary function in children with optic chiasm glioma may be impaired.Objective and hypotheses: We aim to describe the frequency of endocrine abnormalities at diagnosis of the tumor and over the follow-up period in a group of children with chiasmatic glioma and its relation with different variables.Method: Retrospective study using the records of patients under 14 years old followed for optic chiasm glioma. Sex, age a...

Background: The progress made in the treatment of childhood cancer has resulted in better long-term survival rates. Therefore sequelae of treatment have become more important.Objective and hypotheses: To investigate the prevalence of early endocrine disorders in survivors of a childhood tumour within the 1st years after diagnosis.Method: We performed a retrospective medical record review of survivors followed at the endocrine clini...

Background: In paediatric CNS tumours, germ cell neoplasms usually produce endocrine disorders helping an early diagnosis.Objective and hypotheses: To describe presenting symptoms in paediatric CNS germ cell tumours and endocrine abnormalities on follow-up.Methods: We reviewed the records of children and adolescents aged under 14 who were followed in our unit presenting a CNS germ cell tumour. Endocrine abnormalities at diagnosis a...

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

Background: Hypophosphatasia (HPP) is inherited in an autosomal recessive fashion, although symptoms in heterozygous carriers are described. Age at symptom onset determines six clinical forms with different severity and prognosis, but showing phenotypic overlapping.Objective: We aimed to show this genetic and clinical variability by analyzing two cases.Case 1: Male, born at 38+5 weeks with 2250 g (−2.22 SDS) and 45 cm (&#8722...

Background: Central precocious puberty (CPP) is a common condition in girls and has been associated with deterioration of final height (FH). Height prognosis (HP) is critical for the decision of treatment in CPP. There are several methods for predicting FH in CPP but none is completely reliable. Most methods consider bone age (BA), which is very imprecise, but there is no consensus on which method is the best to estimate FH.Objective: To compare the accu...
