Background: The diagnostic use of IGF-1 in children suspected of GHD is based on the assumption that a single determination of this parameter reflects the integrated 24-h GH secretion. IGF-1 levels are low in GHD, but a study found a significantly lower sensitivity in children with organic lesions in the brain.Objective: The aim of this study was to check if there is a statistically significant relation between IGF-1 values in children with GHD with and ...

Background: GH deficiency (GHD) diagnosis includes clinical manifestations, laboratory tests and imaging. There are controversies about the validity of the GH stimulation test. A variety of stimulation tests are used in clinical practice. The biochemical definition of GHD has generally been considered to be a peak stimulated GH concentration <10 ng/ml.Objective: The aim of this study was to check if there is a statistically significant relation betwe...

Background: The Fanconi syndrome (FS) and GH deficiency (GHD) is a rare association. The FS is a dysfunction in the proximal tubule that can be idiopathic or primary. This dysfunction leads to renal loss of bicarbonate, phosphate, glucose, potassium and amino acids. One of the clinical feature is a delay in body growth. The correction of acidosis can protect the loss of growth. According to the prevalence of idiopathic GHD, it would be expected that 1 in 4 000 patients and, wi...

Background: GH deficiency (GHD) occurs due to different aetiologies, morphological abnormalities in pituitary, or mutations leading the individual to lose the genetic growth potential. The pituitary dysfunction can be as GHD alone or associated with other hormones deficiencies. Patients with abnormalities in pituitary may present a greater height loss than others and couldn’t reach the target height (TH) according to final height (FH).Objectives: To...

Hypophosphatasia (HPP) is a rare, inherited, systemic disease caused by mutation(s) of the ALPL gene encoding tissue-nonspecific alkaline phosphatase (ALP), resulting in deficient ALP activity. Asfotase alfa is an enzyme replacement therapy approved for treatment of patients with pediatric-onset HPP. The global HPP Registry is an observational, prospective, multinational study (NCT02306720; EUPAS13514) established to collect real world clinical data from patients of a...

Background: Androgen Insensitivity Syndrome is a common form of 46,XY DSD. In the literature, 85–90% of patients with complete form of Androgen Insensitivity (CAIS) and 30% of patients with parcial form (PAIS) have the AR gene mutation identified, In most cases are found a missense mutation with aminoacid change. Mutations without aminoacid changes (silent mutations) are rarely related to human diseases and have never been identified in patients with CAIS.<p class="ab...

Background: A virus initially considered benign in this age group, SARS-COV-2 has recently been associated with Pediatric Multisystemic Inflammatory Syndrome (PIMS), temporarily associated with COVID-19, a syndrome whose diagnostic determination has a vital relevance since it imposes unfavorable outcomes. This study aims to describe the sociodemographic characteristics of PIMS in Brazil and the factors associated with death by this syndrome.<p class="abste...

Background: Working as a physician is accompanied by emotional and physical stress.Objective and hypotheses: Our study aimed to investigate the effect of working day and night in a children’s hospital on catecholamine excretion as a marker for acute stress and to work out possible gender differences.Methods: 22 paediatricians (ten females, 12 males) aged 27–41 years collected four 12-h urine samples: two during a 24 h-shi...

Background: Familiar isolated pituitary adenomas (FIPA) encompasses the familiar occurrence of isolated pituitary adenomas outside the setting of syndromic conditions such as MEN1 and Carney’s complex, and comprise about 2–3% of pituitary adenomas. About 20% of FIPA have mutations in the aryl hydrocarbon receptor interacting protein gene (AIP), usually associated with a worse outcome.Objective and hypotheses: Evaluate the presence of AIP gene m...

Background: The role of retinol binding protein 4 (RBP4) in the insulin resistance associated with obesity is still unclear and various studies have analyzed the role of its gene polymorphisms as a potential key to understanding the mechanisms involved.Aim: The current study aimed to analyze the relationship between RBP4 levels, the distribution of two SNP (rs3758539 and rs10882280) and the metabolic, anthropometric para...
