Background: Short stature is defined as a height more than two standard deviations below the mean for age and sex. Pathologic causes of short stature include growth hormone deficiency, hypothyroidism, celiac disease, inflammatory bowel disease or other chronic diseases, hormonal abnormalities, and genetic disorders, such as Turner syndrome. Moreover, among other variants of short stature, scholarship also described familial short stature, constitutional delay ...

Introduction: BIPSS before and after desmopressin stimulation has been shown to be a useful tool for diagnosis of ACTH-dependent CD and negative magnetic resonance imaging (MRI)or positive MRI but inconsistent biochemical data, in adult patients. However, little is known about its usefulness in pediatric population.Objective: To evaluate the prevalence of negative MRI, the sensitivity of BIPSS before and after desmopress...

Background: Transsexuality during childhood/adolescence is a complex condition usually ending in dysphoria (GD). The prevalence of transgenderism is increasing in Pediatrics. In the process of sexual reassignment, a correct pharmacological treatment and the knowledge of possible consequences are necessary.Objetive: The objective of this study is to present the evolution of the physical and analytical characteristics and side effects in Transgender childr...

Background: Congenital growth hormone deficiency may be isolated (IGHD) or multiple pituitary hormone deficiency (MPHD). The Sonic Hedgehog signalling (SHH) pathway has an important role in the pituitary development and growth, acting early in ventral forebrain. The SHH signalling mediates its effects through three zinc fingers proteins (Gli1, Gli2 and Gli3), which lead to activation or repression of target genes. Several heterozygous GLI2 mutations have been reported in patie...

Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Background: Maternal autoimmune hypothyroidism can have negative consequences on the fetus: on the one hand, maternal hypothyrosinemia might affect the fetal brain development in the early stages of pregnancy; on the other, thyroid inhibiting antibodies can pass through the placenta. It is currently unclear if these antibodies may affect the newborn’s thyroid function. Consequently, there are no certain indications regarding the management of newborns bor...

Background: To evaluate the efficacy of thyroidectomy, it is necessary to know its complications; however, there is a great discrepancy in the literature regarding its incidence. A greater surgical aggressiveness achieves better control of the disease, but may be accompanied by more complications. Hypocalcemia is the most frequent potential complication after thyroidectomy, but its persistence can lead to serious systemic effects. The objective of this study i...

Introduction: Testicular adrenal rest tumor (TART) is the most important cause of infertility in male with congenital adrenal hyperplasia (CAH). TART is a benign tumor, mainly bilateral (75-80%), usually diagnosed in under-treated CAH male with hypercorticotropinemia, which generally regresses after glucocorticoids therapy adjustment. However, it may determine an irreversible damage by compression and toxic-paracrine effects on the surrounding testicular t...

Short stature is a frequent reason for referral to pediatric endocrinologists and this phenotype has been associated with a large number of gene variations during the last decades, highlighting its complex and heterogeneous etiology. We evaluated the detection rate of the analysis of a selected gene panel in a cohort of patients with short stature defined as height below -2 standard deviations (SD). Overall, 134 patients were included in the study: 73 with GH deficiency (GHD),...

Introduction: Several studies showing a high prevalence of vitamin D deficiency in pregnant women have been published in recent years. Vitamin D deficiency during pregnancy has been related to adverse events both in mother and child. Plasma 25-OH vitamin D (25(OH)D) levels in the newborn are dependent on maternal deposits and show a close correlation with maternal levels; thus, neonates of vitamin D-deficient mothers present a greater risk of hypocalcaemia, rickets and a highe...
