Background: Newborns admitted to the intensive care unit (ICU) are exposed to multiple painful and stressful procedures. It is postulated that high pain exposure in the first weeks of life can have a long-lasting impact on the hypothalamic-pituitary-adrenal (HPA) axis. Assessment of the salivary cortisol (SC) is a useful method for non-invasive monitoring of baseline activity and stress response of HPA axis.Objective: An...

Background: Basal 17OHP levels to indicate an ACTH-stimulation test and post-ACTH 17OHP cut-off levels diagnosing NC-CAH vary among different guidelines.Objective: To establish the performance of basal and post-ACTH 17OHP concentrations for the NC-CAH diagnosis in children with precocious pubarche (PP).Methods: Clinical, biochemical, and molecular analysis from 202 PP patients subm...

The SRD5A2 gene (MIM607306) codes for the type 2 5α-reductase enzyme that catalyzes the conversion of testosterone to its active metabolite, dihydrotestosterone (DHT), essential for the development of the male external genitalia. Pathogenic variants in homozygosis or compound heterozygosis may be responsible for a 46XY Disorder of Sex Development.Case: A 5-year-old girl who was referred to us after the mother noticed lumps on both ...

Introduction: Skeletal dysplasias associated with short stature are caused by inherited cartilage/bone development defects and are often associated with disproportionate short stature. We will present a case of heterozygous NPR2 variants in a patient with ISS.Case Report: A 8 years 3 months aged girl with normal perinatal and neonatal periods came for short stature evaluation. The clinical exam showed: 115.5 cm (-2.45 SD...

Drugs can interfere with immunoassays causing false measurements. Trientine (triethylene tetramine dihydrochloride) is a chelator of copper and is used in the treatment of patients with Wilson's disease as alternative for penicillamine. Trientine mainly increases urinary copper excretion leading to a negative copper balance. Serum concentrations of trientine reached under treatment are not known. This is the first report of an interference of trientine with two chemilumine...

Therapeutic interventions in obesity in addition to the weight loss, seek to improve the profile of cytokines. It is believed that physical activity, even in the absence of significant weight loss, may favorably increase the concentration of irisin and decrease the concentration of chemerin. The aim of the study was to compare the impact of a standard lifestyle intervention (SI) with an intense intervention (II) including controlled increase of daily physical ...

Background and aims: A novel bioactive peptide, mitochondrial-derived peptide (MOTS-c), has recently attracted attention as a potential prevention or therapeutic option for obesity and type 2 diabetes mellitus (T2DM). MOTS-c profiles have not yet been reported in human obesity and T2DM. We aimed to determine circulating MOTS-c levels in obesity and explore the association between MOTS-c levels and various metabolic parameters. Methods: In this case-control study, 40 obese chil...

Background: 17 hydroxylase deficiency is a rare form of congenital adrenal hyperplasia resulting from loss-of-function mutations involving the CYP17 gene. It is characterized by decreased production of glucocorticoids and sex steroids and increased synthesis of mineralocorticoid precursors.Objective and hypotheses: We aimed to identify genetic cause of lack of puberty in a girl and the cause of ambiguous genitalia in her sibling. Fourteen-year-o...

Background: Polycystic ovarian syndrome (PCOS) is the most common cause of oligomenorrhea and hyperandrogenism. Diagnostic criteria for PCOS includes ovarian dysfunction and clinical or biochemical evidence of hyperandrogenism. The differential diagnosis includes congenital adrenal hyperplasia as well as steroid producing tumors.Case presentation: 18-years-old female presented to establish care with a history of PCOS diagnosed at the age of 11 years. She...

Background: In addition to its function in circadian rhythm Melatonin plays an important role in energy metabolism and body weight regulation. In animals pinealectomy induces insulin resistance and administration of melatonin to diabetes prone rats ameliorates their glucose metabolism. Furthermore loss-of-function mutations of the melatonin receptor gene are associated with insulin resistance and DM II in humans.Objective and hypotheses: So far the effec...
