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, ...

Introduction: Barakat Syndrome (HDR Syndrome) is characterized by hypoparathyroidism (H), sensorineural deafness (D) and renal disease (R) caused by an autosomal dominant inheritance, being mostly associated to deletions in chromosome 10p14 or mutations in GATA3 gene.Case Report: A 9 years old male was admitted at an emergency complaining of upper and lower limbs pain and contractures that progressed with periodic tetany...

Introduction: Complications are frequently reported post hypospadias repair and there is a need to understand the factors that influence their occurrence.Aim: The aim of this study was to identify the occurrence of complications in boys with hypospadias that are in the I-DSD Registry.Methods: Data from boys born with hypospadias between 2010-2020 were obtained from the I-DSD regist...

Newer studies have indicated that vitamin D has more widespread effects than the classical effects on bone and calcium-phosphate homeostasis. The presence of the vitamin D receptor (VDR) in the testis and male reproductive tract indicates a role for vitamin D in male reproduction. Indeed, vitamin D deficiency and global knock out models of VDR or CYP27B1 in rodents have shown that vitamin D and calcium are important regulators of male reproductive function. Several groups have...

Introduction: Aromatase excess syndrome (AEXS) is a rare, autosomal dominant disorder, characterized by enhanced extraglandular aromatization of androgens and estrogen excess. Genomic rearrangements in chromosome 15q21 are found to result in overexpression of the aromatase gene CYP19A1. In males it is characterized by pre- or peripubertal gynecomastia, hypogonadotropic hypogonadism, advanced bone age and short adult height. Only a few female patients have been...

Progeria syndromes are rare in children and include several diseases which lead to premature ageing already in children. Therefore, the pediatrician may be confronted with diseases which are normally seen only in persons with advanced age. We report about two children with progeria, in whom diabetes type 2 become manifest early and with a fulminant course in one patient. The first boy was known with Cockayne syndrome, which belongs to the progeria syndromes. He suffered from l...

Background: The BoneXpert method for automated determination of bone age from hand X-rays has always included a determination of the Bone Health Index (BHI) from the cortical thicknesses in the metacarpals.Objective and hypotheses: The aim was to extend this so-called digital X-ray radiogrammetry method into adults, and present reference curves for BHI and three other indices: the metacarpal index, the Exton-Smith index and the volume-per-area (proportio...

Background: The BoneXpert method for automated determination of bone age (BA) from hand X-rays was introduced in 2009, covering the Greulich-Pyle BA range up to 17 years for boys and 15 years for girls.Objective and hypotheses: To present an extension of the BA range of the automated method up to 19 years for boys and 18 years for girls and to validate it against manual rating.Method: The extension was developed based on images fro...

Background: In adults, autonomously functioning thyroid nodule (AFTN) rarely require cytologic evaluation and hyperthyroidism is often treated with radiojod (131J). In children and adolescents with AFTNs thyroid carcinoma was identified in about 10%.Results: An 17-year-old adolescent presented with symptoms of hyperthyroidsm. She suffered from agitation and headache. Thyroid function tests revaled a suppressed TSH (0.10 mIU/ml (reference range 0.51–...

Background: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease which occurs in the setting of insulin resistance and increased adiposity. It has rapidly evolved into the most common liver disease seen in the pediatric population. NAFLD can be divided into non-alcoholic fatty liver (NAFL), which denotes bland steatosis, and non-alcoholic steatohepatitis (NASH), which is marked by steatosis and lobular inflammation and hepatoce...
