Background: Polyuria and polydipsia syndrome (PPS) workup is not straightforward, especially in children. Basal investigations are often not reliable in distinguishing among diabetes insipidus (DI), central (CDI) or nephrogenic (NDI), and primary polydipsia (PP). Water deprivation test (WDT) is often essential, although uncomfortable and not always reliable enough to recognize partial DI. Plasma AVP investigation is not routinely used in the diagnostic pathway...

Introduction: The National Registry of Civil Status through circular 33 of February 24, 2015 instructed the guidelines for the allocation of a sex through an inscription on the Civil Registry of Birth for intersexual minors.Objective: To create clinical and medical awareness on the importance of making an accurate diagnosis of Congenital Adrenal Hyperplasia CAH in order to avoid adverse effects due the omission of the due diligence by violating of the pr...

Delayed puberty (DP) is defined as a retardation of sexual maturation beyond the expected age, which conventionally is between 8 and 13 years in females. Since DP due to hypogonadism requires a specific treatment, it is crucial to promptly define the underlying pathogenesis and identify a tailored program of care. Hormonal therapy is essential to promote the development of secondary sexual characteristics, bone, muscle, and social, sexual, and psychologic skills. Despite the o...

Cause: The Colombian Society of Urology published in May 1993; A Modern Approach to Sexual Ambiguity Syndromes which discuses sexual differentiation and sexual disorders associated with sexual development to determine a binary gender with surgical reconstruction.Objective: Gather the members of ACEP (Colombian Association for Pediatric Endocrinology) to clarify, update and create an approach of human sexuality from a biosociocultural pe...

Background: Response to rhGH treatment is variable among GH deficiency (GHD), GH insensitivity and several intermediate conditions.Aims and objectives: To compare baseline parameters and response to rhGH treatment in eight diagnostic categories of patients with short stature.Methods: We selected 125 prepubertal children presenting at least 2 years of rhGH treatment (mean 5.29 years, range 2–15.6 years), hormonal and clinic par...

Introduction: Homozygous loss-of-function mutations of the growth hormone receptor (GHR) gene result in GH insensitivity due to a dysfunctional receptor protein. Heterozygous mutations may result in a variable clinical spectrum ranging from normal height to severe short stature. Gain-of-function variants have been reported rarely.Case Report: We hereby report the case of a Russian boy who was referred to our endocrine o...

Background: However, no study has considered the effect of a supernumerary X chromosome on bone mineral status and bone metabolism.Objective and hypotheses: To evaluate bone mineral status and metabolism in a cohort of patients with nonmosaic triple X syndrome.Method: Nineteen girls (median age 10.9, range 7.7–15.9 years) with nonmosaic triple X syndrome were cross-sectionally studied and compared to an age- and body-size-matc...

Background: Newborn screening for congenital adrenal hyperplasia (CAH) is based on the determination of 17-hydroxyprogesterone (17OHP) on blood and its need is confirmed by the most recent guidelines on the subject. In Italy this screening is not mandatory, and its application is on a regional basis. Among its disadvantages, it is well known the high frequency of false-positives, in particular in premature babies and those born small for gestational age. Howev...

Background: Neonatal hypocalcemia is a common disorder, occurring more often in premature, low birth weight and asphyxiated infants, as in infants born to mothers with diabetes. Nevertheless its aetiology is heterogeneous ranging from iatrogenic, idiopathic and inherited metabolic abnormalities. Among these, Autosomal Dominant Hypocalcemia (ADH) is a rare syndrome characterized by the presence of inappropriately low concentration of circulating parathyroid hor...

Introduction: Cryptorchidism has usually been managed using a surgical approach, with little attention to the underlying pathophysiology.Objectives: To assess gonadal function before treatment in prepubertal boys with cryptorchidism.Methods: In a cross-sectional study we reviewed all clinical charts of patients encoded with the diagnosis of cryptorchidism in the database of a paediatric tertiary hospital, between 2000 and 2017. Inc...
