A prolactinoma is the most common pituitary adenoma, but a pituitary adenoma is rarely diagnosed in children. Corticotropinomas and somatotropinomas are observed, whereas clinically non-functioning pituitary adenomas, TSH-adenomas and gonadotroph adenomas are very rare in children; a minor percentage of pituitary tumours are aggressive. Genetic cause and syndromic disease are more often seen in children and adolescents with a pituitary adenoma compared to adults, and it is nec...

Clinical Case Description: Patient, 14 years 6 months old, complained of irregular menstrual cycle. On clinical examination, sexual development was Tanner 4, Me at 13 years old, the girl had 3 menses, with a last delay up to 8 months. Single terminal hairs along the white line of the abdomen, areola. The patient had epicanthus and narrowed eye slits of different sizes. She was operated on for congenital blepharophimosis in infancy. No one has similar problem...

Background: Newborn screening for congenital adrenal hyperplasia (CAH) has been shown to reduce time to diagnosis, and thus morbidity and mortality. Internationally, newborn screening for CAH continues to expand and screening techniques have improved, with the implementation of second-tier testing and use of gestational age stratification. The aim of this study was to examine the incidence and spectrum of early clinical presentations of CAH in an unscreened po...

Objective: Hereditary hypophosphatemic rickets is a rare renal phosphate wasting disorder causing burden on pediatric patients despite conventional treatment of phosphate and calcitriol. The aim of this study is to analyze genetic and clinical variability of children with X-linked hypophosphatemic rickets (XLHR), focusing on short term, long term and pubertal impact of conventional treatment. Design: Retrospective cohort studyMet...

Autosomal dominant pseudohypoparathyroidism type-Ib is characterized by renal parathyroid hormone resistance, with resultant hypocalcemia and hyperphosphatemia. This disorder is associated with an isolated loss of methylation at GNAS exon A/B and most patients carry maternal microdeletions in the neighboring STX16 gene. The shortest deletion overlap is a 1.2-kb region spanning STX16 exon 4 and thought to harbor a cis-acting element regulating GNAS A/B methylation. However, abl...

Introduction: Congenital Hyperinsulism (CHI) is a common cause of recurrent and persistent hypoglycemia in the neonatal period. Diazoxide is the first line medication used for the management of CHI. We report the clinical profile and the management outcome of a large cohort of patients with diazoxide responsive CHI.Methodology: A retrospective data collection including antenatal, perinatal and postnatal clinical parameters, laboratory di...

Background: Turner syndrome (TS) predisposes to obesity and related metabolic disorders and presents a high risk of congenital heart defects. Growth hormone (GH) treatment used in TS girls also affects the parameters of carbohydrate-lipid metabolism. Thus, the search for new markers that could be early predictors of metabolic disorders seems to be justified.Objective and Method: The assessment and comparison of MMP-1, MMP-2, MMP-9 (matri...

Loss of function mutations in SGPL1 (sphingosine-1-phosphate lyase) give rise to a multisystemic syndrome with predominating features of primary adrenal insufficiency (PAI) and steroid resistant nephrotic syndrome. Retrospective analysis of our patient cohort and the wider literature also demonstrated primary gonadal insufficiency in a third of male patients with microphallus and bilateral cryptorchidism (all with concomitant adrenal disease and high mortality in infa...

Background: Postnatal linear growth is characterized by a steady decline of growth velocity in healthy individuals, with the exception of sex-steroid induced pubertal growth. Pharmacologic interventions in growth disorders are limited to systemic application of growth factors such as growth hormone, and CNP analogues in conditions with FGFR3 overactivation. Tyrosine kinase receptor inhibitors (TKI) represent a heterogenous group of drugs, mostly used for oncol...

Background: Human milk is considered the most advantageous source of nourishment for infants. Although there is a growing body of evidence showing that human milk feeding fosters early neurodevelopment, the underlying process is still not completely known. Indeed, clinical and animal research has linked human milk to enhanced myelination in the infant's central nervous system, however, access to human oligodendrocytes and neurons in the early stages of develop...
