Introduction: The ideal TSH filter value (TSHf) in the neonatal screening tests for Congenital hypothyroidism (CH) is worldwide controversial. Local cutoff point of TSHf was 9.0 mIU/L until recently. OBJECTIVE: To evaluate the clinical and laboratory characteristics of newborns with CH (confirmatory serum TSH > 10 mIU/L) after a lower TSH cutoff. METHODS: Cross-sectional study using data from Neonatal Screening Reference Center of State Rio Grande do Sul, ...

Background: Most reports on gonadotoxicity associated with chemotherapy of acute lymphoblastic leukemia (ALL) comes from studies in adults, and they are mainly focused on the sensitivity of testicular germ cells. Little attention has been placed on Sertoli cells in prepubertal patients, even though Sertoli cell function is essential for adult spermatogenesis.Objective: To evaluate Sertoli cell function in prepubertal boys who receive chemotherapy for ALL...

Background: 2015 ATA Guidelines for management of medullary thyroid cancer (MTC) include C634 RET codon mutation in ‘High risk’ group, recomendating prophylactic thryroidectomy before 5 years old based on serum basal calcitonin levels (SBCt).Objective and hypotheses: We present 14 pediatric patients with C634 RET codon mutation, who underwent prophylactic thyroidectomy in our center, their clinical and analytical features and anatomopathologica...

Background: HABP2 is an extra-cellular matrix protein involved in cell proliferation. Recently, HABP2 was proposed as responsible for the familial clustering of Differentiated Thyroid Carcinoma (FDTC). However, its involvement was questioned by subsequent studies revealing high prevalence HAPB2 polymorphisms (SNPs) in the general population, leaving its pathogenic role uncertain.Objective and hypotheses: To identify genetic HABP2</e...

Background: FGF21 is a metabolic and growth regulator.Aim: To investigate the role of FGF21 during growth in infancy.Methods: Cohort of 40 term (T) and 40 preterm (PT) newborns whose length and weight were evaluated prospectively at birth, 6 months, and 12 months. Blood samples for FGF21, IGF1, leptin, insulin and glucose were collected at 6 and 12 months. In addition, FGF21, I GF-I, leptin, and insulin were measured in cord blood ...

Background: The most common form of congenital adrenal hyperplasia (CAH) is 21-hydroxylase deficiency, which in its severe form can cause genital ambiguity in females. This can be ameliorated by administering dexamethasone to the mother.Case: This is a family whose index case is a first son diagnosed by Madrid Newborn Screening Program of CAH with salt-wasting form due to 21-hydroxylase deficiency. Mutation analysis revealed: ‘hybrid deletion’ ...

Background: There are limited data available on the efficacy and safety of GH treatment in very young (<30 months) short children, born small for gestational age (SGA).Objectives: To determine the effect of 24 months of GH treatment on body height, BMI, and head growth as well as overall psychomotor development (using the Bayley Scale of Infant Development (BSID-II)) and demonstrate its safety in young (aged between 19 and 29 months) short SGA childr...

Background: Controversial data exist on the possibility that inhaled glucocorticoids (IGs) affect growth in children with mild-to-moderate asthma. The majority of these studies are short-term reports lacking long-term assessment until the achievement of final height (FH).Objectives: To assess whether IGs affect growth and FH in asthmatic children compared to controls.Methods: 113 asthmatic (57/56 (males/females)) were compared to 6...

Background: Nutritional rickets (NR) is the most common growing bone disease, and vitamin D deficiency (VDD) may predispose to other diseases (diabetes mellitus, cancer, and multiple sclerosis). Maternal VDD and exclusive breastfeeding without supplementation are the most frecuent causes of NR in the neonate. VDD is still a problem in Europe. There are few reports of maternal hypovitaminosis D and rickets in bottle-fed infants during early infancy. We report a case of Nutritio...

Background: The administration of GH on paediatric patients to optimize the longitudinal growth, can modify some cardiovascular risk factors due to their effects on metabolism.Objective and hypotheses: Evaluation of the effect of GH on total cholesterol blood levels (TCBL), fasting blood glucose concentration (FBGC), blood pressure (BP) and BMI, comparing these variables before starting treatment, after a year and at the end. And it also assesses whether...
