The Ovotesticular Disorder of Sexual Development (OT DSD) is a rare condition characterized by histologic demonstration of both ovarian and testicular tissue in the same individual. Descriptions in literature usually have small samples and do not include patient evolution data. The aim of this study is to describe clinical, biochemical and histological findings, as well as long-term outcomes (including onset and progression of puberty) in patients with OT DSD, accompanied betw...

Background: Obstructive sleep apnea syndrome (OSAS) in children is a common medical disorder, often associated with adenoid and tonsil hypertrophy. The prevalence of OSAS has been increasing due to alarming rates of obesity in childhood. This is a very concerning subject since there is a higher risk of cardiovascular outcomes in patients with elevated BMI and OSAS.Objective and hypotheses: The aim of this study is to report a hazardous case regarding chi...

The high rate of false-positive (FP) results in congenital adrenal hyperplasia newborn screening (CAH-NBS) worldwide challenges NBS-programs and reinforces the need of high specificity subsequent tests. Few studies assessed the efficacy of different serum steroids by the available methodologies. Serum 21-deoxycortisol-21DF demonstrated a high diagnostic accuracy in CAH children/adults but was not evaluated in the NBS context. Objective: to evaluate the efficacy of confirmatory...

Background: The exaggerated adrenarche is an extreme variant of the maturation of the adrenal cortex, often associated with hyperinsulinemia and obesity. Hyperandrogenism by congenital adrenal hyperplasia (CAH) and adrenal neoplasms are differential diagnoses.Case report: Male, 8 years and 3 months, who came from another service with diagnosis of Precocious Puberty and Obesity, already being treated with Leuprolide acetate for 1 year and half. His compla...

Background: Mixed gonadal dysgenesis (MGD) is a heterogeneous group of gonadal, chromosomal and phenotypic abnormalities. The diagnosis is based on the presence of testicular tissue and streak.Objective and hypotheses: Casuistics description of patients with MGD in our hospital.Method: A retrospective analysis of medical records.Results: We studied 15 patients. The age at first visit ranged from two weeks to ...

Background: Childhood obesity is one of the most prevalent and challenging health care concerns. In this context, insulin resistance (IR) is an important disorder with strong association with metabolic (type 2 diabetes, hypercholesterolemia) and cardiovascular (hypertension, atherosclerosis) outcomes. Clinical trials have been showing Metformin as an effective drug on reducing the IR and BMI. However, there is little data on use of metformin in children....

Introduction: Down syndrome (DS) is a common condition and its association with disorders of sex development (DSD) is quite rare.Case report: We report four DS patients with DSD. Patient 1: 22 days old, undefined sex. 2.5 cm phallus, non-palpable gonads, and perineal urethra. Testosterone=332 ng/dl (at 1 mo), uterus on ultrasound, 47,XY +21 karyotype. A gonadoblastoma on the left gonad and a streak on the right. Dx – DSD Mixed Gonadal Dysgenesis. Pa...

Introduction: McCune–Albright syndrome (MAS) is a genetic disorder characterized by constitutive activation of Gsα, resulting in excessive activity of multiple hormones. The most known clinical characteristics are the presence of polyostotic fibrous dysplasia (FD), hyperpigmented skin spots, and gonadotropin-independent precocious puberty (PP). However, other endocrine manifestations can be found like hypophosphatemic rickets due to FGF-23-induced renal phosphate was...

Introduction: Central diabetes insipidus (CDI) is a condition in which large volumes of diluted urine are excreted due to vasopressin deficiency. In most patients, DI is caused by the destruction of neurons in the hypothalamus and the known causes include local inflammation or autoimmune aggression, vascular and infiltrative diseases, as well as compressive masses, trauma or midline cranial malformations. CDI caused by cytomegalovirus (CMV) infection is a very rare condition.<...

Introduction: The Insulin Autoimmune Syndrome (IAS or Hirata Disease) is rare among children. Non-ketotic hyperinsulinaemic hypoglycemia and the presence of insulin auto-antibody (IAA) are the conditions to diagnose the syndrome. The occurrence of hypoglycemia is due to the binding of the antibody to the insulin molecule at the immediate postprandial, followed by this binomial dissociation, which releases free insulin on serum and triggers symptomatic hypoglycaemia.<p clas...
