Background: Newborn screening for CAH is effective in identifying the severe cases; however, the high rate of false-positive (FPR) results remains an important issue. Therefore, positive neonatal results must be confirmed by serum 17OHP levels, which present a great overlap among all forms.Objective and hypotheses: To evaluate the utility of molecular analysis to improve CAH diagnosis in NBS program.Method: Between 1999 and 2014, 8...

Background: Main concerns of Congenital Adrenal Hyperplasia Newborn Screening (CAH-NBS) are the high false-positive results (FPR) rate, low positive predictive value (PPV) and heterogeneity of confirmatory tests. Considering the CAH-NBS implementation in our country, our.Objectives: Objectives are to optimize the Neonatal 17OH-Progesterone (N17OHP) cutoffs and to evaluate the best serum confirmatory test.Methods: 473 983 newborns w...

The high rate of false-positive (FP) results in congenital adrenal hyperplasia newborn screening (CAH-NBS) worldwide challenges NBS-programs and reinforces the need of high specificity subsequent tests. Few studies assessed the efficacy of different serum steroids by the available methodologies. Serum 21-deoxycortisol-21DF demonstrated a high diagnostic accuracy in CAH children/adults but was not evaluated in the NBS context. Objective: to evaluate the efficacy of confirmatory...

Background: Most congenital adrenal hyperplasia (CAH) patients carry mutations derived from conversion events involving the pseudogene, and the remaining carry new mutations varying according to ethnicity. A good genotype-phenotype correlation is observed, allowing the use of molecular analysis in clinical practice.Objective and hypotheses: To review the molecular diagnosis in a large cohort of CAH patients in order to create a diagnostic panel in our po...

Background: Few studies have focused on the quality of life (QoL) of patients with disorders of sex development (DSD).Objective and hypotheses: Our aim was to evaluate QoL in DSD patients with defined diagnoses followed until adulthood in a single tertiary centre.Method: Subjects: adult DSD patients (56 patients with 46,XX DSD – 49 with female social sex and seven with male social sex as well as 88 patients with 46,XY DSD &#15...

Background: Isolated Growth Hormone Deficiency (IGHD) is usually associated with a delayed bone age. A genetic cause for IGHD is more frequently found in patients with familial cases and/or consanguineous parents.Objective and hypotheses: To diagnose the genetic cause of IGHD and clarify the unusual clinical presentation of advanced bone age in one patient born to consanguineous parents.Method: Sanger sequencing of GH1, <e...

Introduction: DSD patients present varied degrees of atypical genitalia. The social sex assignment and the surgery decisions must be proceeded by a multidisciplinary team approach with the family. Surgeries should be only performed by experienced surgeons. The current trend is the early correction, but some patients and non-governmental entities argue that the surgeries should be delayed until the patient’s consent.Objective...

Context: Differences in sex development (DSD) represent a broad spectrum of conditions that can present at different ages to various healthcare professionals with different backgrounds.Design: This is a retrospective, observational cohort that includes all DSD subjects referred to a multi-professional DSD team over a period of 41 years (from 1980 to 2021).Participants: A total of 6...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

Introduction: Although the safety and effectiveness of recombinant human growth hormone therapy (rhGH) has been reported for several years, the level of consensus on the outcomes that should be reported is unclear. The aim of this systematic review is to study the frequency of reporting of these outcomes in children with GH deficiency (GHD).Methods: A systematic review was performed in Medline, Embase, Cochrane Central R...
