Introduction: Type 1 diabetes mellitus (T1DM) is associated with significantly higher cardiovascular disease mortality compared to the general population, even when glycated hemoglobin (HbA1c) is less than 7.0%. Inadequate body composition may increase the risk.Aim and Methods: To evaluate body composition of a group of pediatric patients with T1DM, from Portuguese Pediatric Endocrinology/Diabetic Clinic, using the bioim...

Background: Central precocious puberty (CPP) is a rare disorder that occurs five times more often in girls. Patients are mostly healthy children whose pubertal maturation begins at an early age: girls <8 years; and boys <9 years. Imaging usually reveals no abnormalities in girls while in boys abnormal MRI findings are more frequent.Objective and hypotheses: We describe three cases of CPP in children with autism, a rarely reported association....

Background: Wolfram syndrome (WS) is an autosomal recessive neurodegenerative disorder characterized by non-autoimmune diabetes mellitus and progressive optic atrophy. WS includes other possible disorders, such as diabetes insipidus, sensorineural deafness, genitourinary tract problems, neurological or psychiatric disorders and others.Case presentation: A 12-years-old boy presented with glicosuria and shortly developed insulin-dependent diabetes mellitus...

Introduction: CHARGE syndrome is a rare constellation of congenital malformations caused by mutations in CHD7 gene. The acronym stands for coloboma, heart defect, choanal atresia, retarded growth and development, genital hypoplasia, ear abnormalities, and/or hearing loss. Endocrine disorders associated with this syndrome include hypogonadotropic hypogonadism, ...

Introduction: Thyroid dysfunction is the most common side effect of amiodarone therapy, ranging from subclinical changes to overt clinical thyrotoxicosis (AIT) and/or hypothyroidism (AIH). Two major types of AIT have been described: type I usually develops in multinodular goiter or in preexisting Graves’ disease where an overload of iodine is responsible for the overproduction of thyroid hormones, and type II presents as a destructive thyroiditis, with release of pre-form...

Background: The excessive consumption of sucrose, primarily used in sweetened beverages, has been considered an important inducer of cardiometabolic diseases. Besides the association between metabolic syndrome and fructose found in animal models, literature is lacking prospective studies in humans, especially in paediatric ages.Objective and hypotheses: We assessed the effect of sugar-sweetened beverages reduction on markers of metabolic syndrome in obes...

Background: Several studies have suggested that vitamin D supplementation in early childhood is successful in decreasing the risk of type 1 diabetes (T1D) through a complex immunomodulatory role. However, Intervening in disease once clinical symptoms have appeared and autoreactive immune responses are active might be more challenging. Controlled trials with vitamin D supplementation in recent-onset T1D have shown mixed results.Objective and hypotheses: T...

Background: Testicular tumours are an unusual cause of prepubertal gynecomastia. However, in boys with Peutz-Jeghers Syndrome (PJS), a rare autosomal dominant disorder caused by mutation in LKB1/STK11 gene, is mandatory to exclude this etiology, given the well-known association between PJS and Large-Cell Calcyfing Sertoli-Cell Tumor (LCCSCT). This mutation promotes aromatase overexpression in neoplastic Sertoli-cells, leading to gynecomastia.Case present...

Background: Endocrine disruptors (ED) are chemicals that can mimic hormones and interfere with their receptors, causing endocrinological abnormalities.Clinical report: We present the case of a previously healthy, melanodermic, two-year-old female, who had a three-month evolution of clitoromegaly and generalized hypertrichosis. Endocrine blood work showed suppressed serum androgens suggesting steroid exogenous contact. Karyotype, bone age...

Background: Endogenous Cushing’s Syndrome (CS) is a rare disease in children, and corticotropin-independent forms are even scarcer. In childhood it carries a significant burden, resulting from both prolonged hypercortisolism long-term effects and treatment-associated morbidity.Case Report: A 23-month-old girl presented with irritability, central obesity with rapid weight gain and arrested linear growth, cushingoid facies with facial...
