Background: Newborn (NB) screening programs show a wide variation in congenital hypothyroidism (CH) incidence along the years.Objective and hypotheses: To describe CH incidence, etiology, associated malformations and Down Syndrome (DS) in children detected by our NB Screening Program. To search differences between permanent CH (PCH) and transient forms (TCH).Method: We analyzed NB with positive screening results referred between A...

Introduction: In children with classical congenital adrenal hyperplasia(CCAH) linear growth allows monitoring metabolic control. Precocious puberty could compromise their growth. There are few studies in patients with CCAH diagnosed by neonatal screening(NS) about this subject.Aims: To analyze linear growth and precocious puberty in children with CCAH detected by NS.Method: Thirty-...

Introduction: Hyperthyroidism (HT) is a condition characterized by inappropriately high thyroid hormone (TH) activity at receptor level, due to high synthesis and secretion of TH by thyroid gland. Antithyroid drugs as methimazole (MMI) are used as the first-line therapy in children. However, the optimal treatment duration and the predictive remission factors are still controversial.Objective: To investigate outcome of MM...

Introduction: Autoimmune thyroid diseases (ATD) are the most common autoimmune disorders associated with type 1 diabetes (T1D). Most patients present hypothyroidism. Although hyperthyroidism is less frequent, severe forms of thyrotoxicosis coexisting with diabetic ketoacidosis (DK) have been described in children with either preexisting diabetes, thyroid disease, or both. Celiac disease (CD) incidence is higher and ranges from 0.6-16.4%....

Mandatory lockdown during COVID 19 pandemic obstaculized access to medical attention. Newborn screening (NBS) for congenital hypothyroidism (CH) in Buenos Aires province has been obligatory since 1995 and performed sustainedly. CH causes mental delay if not diagnosed and treated early.Objectives: The aim of this study was to determine if mandatory lockdown changed time of established NBS diagnosis steps.Mat...

Background: Pelvic ultrasonography (PUS) of the uterus and ovaries allows the diagnosis of changes in sexual development. However, the reference values used in Spain originate from old studies conducted in other countries.Objective: To determine reference uterine and ovarian measurements by PUS and according to pubertal status and bone age in a Spanish population of healthy girls aged between 6 and 12 years.<p class=...

Introduction: Hashimoto's thyroiditis (HT) and Graves' disease (GD) become increasingly common in children's population. Pathogenesis of autoimmune thyroid diseases (AITD) bases on coexistence of genetic predisposition and environmental triggers which finally drive to breakdown of immune tolerance. Many mechanisms in human body moderate process of inflammation. While some of them answer for up-regulation, some agents like B regulatory lymphocytes (...

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...

Background: Hypospadias is one of the most common congenital abnormalities in male. Nowadays, hypospadias surgical repair has become highly demanding and deeply investigated with more than 300 corrective procedures. Its success is assessed by the "reoperation rate" that occurs short after the surgery within a brief follow-up (6-12 months). However, short-term outcomes may not reflect the long-term ones, as hypospadias repair may influence adolescence a...

Papillary thyroid cancer (PTC) is the most common thyroid tumor in childhood and adolescence. Most of these patients are referred with locally advanced and/or distant disease at the moment of diagnosis. Whenever is possible, these patients should be offered a total thyroidectomy and radioiodine remnant ablation. However, this approach is not always possible to perform, becoming these tumors as unresectable. These critical cases could benefit from the neoadjuvant treatment with...
