Disorders/differences in sex development (DSD) are defined as congenital conditions in which development of chromosomal, gonadal or anatomical sex is atypical. 46,XY DSD include defects in androgen synthesis or action or complete (CGD)/partial (PGD) gonadal dysgenesis. The aim of this study was to characterize the molecular genetic diagnosis of individuals with 46,XY DSD followed at Garrahan Pediatric Hospital.Medical records of 140 patients (P) followed...

Sex chromosome disorders, including sex chromosome mosaicism, result in a large clinical spectrum. There is scarce information about the histological pattern of these gonads.Aim: to characterize the histology and cell markers pattern in gonads of patients with chromosomal mosaicism.Gonadal biopsies from thirteen patients with chromosomal mosaicism, including chromosome Y were studied. Six were rearing as male and s...

Background: Aromatase deficiency is a rare autosomal recessive disorder produced by CYP19 gene mutations. 46XX affected patients presented with ambiguous genitalia leading to early identification. Most 46XY affected patients presented normal external genitalia and the condition often remains undiagnosed until late puberty. Information on pubertal development in affected boys is scarce since to the present date only two patients, younger than 4 years of age, without lo...

Background: During the 1st months of postnatal life serum luteinizing hormone (LH) levels in girls are lower than in boys. The mechanism of this sex difference is not known. It has been proposed that foetal or perinatal androgenic steroids have an effect on the control of LH secretion.Objective and hypotheses: To study the possible influence of high levels of androgens on serum gonadotropins during the 1st months of life in a cohort of nine 46,XX testicu...

Background: National and international guidelines recommend thyrotropin (TSH) determination as the most sensitive test for detecting primary congenital hypothyroidism (CH) in newborn screening programs. A strategy of a second screening at 2 weeks of age, or 2 weeks after the first screening was carried out, is also recommended in preterm, LBW and VLBW neonates, twins, neonates admitted in NICU, and babies with specimen collection within the first 24 hours of life [1–3]. H...

Background and Aims: The treatment of type 1 diabetes (T1D) requires a great involvement of the patient to achieve optimal blood glucose levels. Technological devices have been developed for individualized treatment, fewer interventions of the patient, and evidence of improved metabolic control. The aim of the study is to know data on metabolic control in a group of pediatric patients with T1D treated with new technologies, compared to patients treated with mu...

Introduction: Achieving metabolic control in children with type 1 diabetes (T1DM) is not an easy task. Despite the new profiles of insulins and therapies with continuous infusion, hypoglycemia continue to be the most important barrier that prevents us from correctly controlling these patients.Close control of capillary glycaemia is important for treatment adjustment. This self-control provides us with static information about capillary g...

Introduction: To optimal glycemic control without hypoglycemia must be the aim of insulin treatment for all patients with type 1 diabetes (T1DM). Despite the advantages of the basal-bolus insulin regimens with MDI, hypoglycemia presents a major barrier in achieving desirable blood glucose levels. Degludec is a new basal insulin analog with longer half-life and lower variability.Objetive: To investigate the differences between long-acting insulins glargin...

Background: Permanent neonatal diabetes (PND)with heterozygous mutations of KCNJ11, respond to treatment with sulphonylureas. We report a case of PND in a baby, and mother previously mis-diagnosed with Type 1 DM. Both were switched from insulin to oral sulphonylureas. We evaluate the response and evolution.Case report: A male newborn at 37 weeks’ gestation, with a birthweight 2750 g (40thC) and length 48 cm (40thC), was admitte...

Background: Hepatic steatosis is common in obese children. The pathophysiology remains unexplained but it is known that insulin resistance and hypertrilycerdemia are involved in its development.Objective and hypotheses: To analyse the prevalence of hepatic steatosis identified by ultrasound, as well as features and anthropometric data in our population divided into two groups: (with steatosis and without steatosis) to assess the risk factors.<p class...
