Background: The approach to investigating a newborn with a suspected DSD is likely to vary between centres and may be influenced by local availability.Method: To explore the current diagnostic practice and needs, an international survey of 124 paediatric endocrinologists, identified through DSDnet and the I-DSD Registry, was performed in 2014.Results: A total of 77/124 (62%) clinicians, in 74 centres, from 38/42 (91%) countries res...

Introduction: Indonesia, an archipelago with approximately 17,000 islands and 34 provinces has around 4.8 million babies born annually, yet only 2-3% undergo newborn screening (NBS) resulting in high preventable disease burdens. Currently, the country only has 1 newborn screening project which will be relaunched and aimed to cover 30-40% of babies. Health policy plays a huge role in determining the day-to-day lives of children, families, and health professiona...

Introduction: Early identification of classic 21OH-Congenital Adrenal Hyperplasia (21OH-CAH) through newborn screening (NBS) is crucial to prevent adrenal crises, especially in males. Today 21 OH-CAH NBS is performed in 5/21 regions of Italy. This study aims to report the results of 21OH-CAH NBS in Italy from 2006 to 2019.Methods: All patients underwent a dried blood spot (DBS) test for 17OH-progesterone (17OHP) within t...

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: 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: 17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) deficiency is a rare cause of 46,XY sex reversal due to a defect in conversion of androstenedione to testosterone. It is autosomal recessively inherited and caused by mutations in 17HSD3.Objective and hypotheses: To define clinical and laboratory characteristics of 17β-HSD3 deficiency during neonatal period.Method: An 8-day-old newborn with female externa...

Background: 17β-Hydroxysteroid dehyrogenase type 3 (17βHSD-3) deficiency is an autosomal recessive form of 46,XY disorder of sex development (DSD). 17βHSD-3 is present almost exclusively in the testes and converts androstenedione to testosterone. The diagnosis can be easily missed in early childhood as the clinical presentation may be subtle. The most frequent presentation of 17βHSD-3 deficiency is a 46,XY individual with female external genitalia, labial f...

Background: Brain abnormalities like cerebral midline malformations (CMM) can be detected by fetal sonography. CMM with neonatal hypopituitarism may cause severe hypoglycemia.Case presentation: We report about three cases of term eutrophic newborns, which all presented with severe neonatal hypoglycemia despite prenatally diagnosed CMM. All three patients were born vaginally and were immediately breastfed after normal postnatal adaptation. In the first ca...

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare pediatric disorder. The classic form occurs in 1:15,000 births worldwide. Osteogenesis imperfecta is a rare bone disease occurring in 1 in 15,000 to 20,000 births. Cow’s milk allergy (CMA) is of the commonest food allergies in early life. Our case presents the co existence of the abovementioned entities in a patient.Case report:</str...

Introduction: Although there are several studies on the incidence of congenital hypothyroidism (CH), there are few data showing incidence and evolution of CH detected by the second newborn screening (NBS).Objectives: To assess the incidence of CH in Lombardia region and the percentage of patients identified by the 2ndNBS. To describe the clinical features and evolution of CH patients detected by the 2nd</...
