Background: Patients with Turner Syndrome (TS) are at high risk for congenital heart disease (CHD), aortic dilatation and dissection with increased mortality and morbidity. Thoracic gadolinium-enhanced MRI angiography allows clear imaging of all great vessels and revealed a spectrum of silent vascular anomalies (VA), both venous and arterial, undetected at Echocardiography.The aim of this study is to retrospectively evaluate the prevalen...

Background: Studies on the follow-up of 46,XY partial gonadal dysgenesis (PGD) patients till adulthood are scarce and it is important to provide information to parents on the prognosis of gonadal dysgenesis.Objective and hypotheses: To analyze the long term outcomes of 46XY PGD patients in both social sexes regarding testosterone production, social sex adaption and genotype.Method: Retrospective longitudinal study conducted at Hosp...

Background: A high risk of congenital hypothyroidism (CH) has been documented in multiple pregnancies. Over the years special screening procedures for preterm and twin babies (re-screening at 2–4 weeks of life) have been adopted by many screening laboratories worldwide. However, no extensive studies have been performed to verify how many co-twins with negative test at first screening (3–5 days of life) become positive at re-screening, and the utility of a long-term f...

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...

Background: Patients with 46, XY DSD present conflicts and issues related to gender identity (GI) and change to male social sex in patients registered in the female social sex is not rare. The HTP test is a projective psychological test, which assesses aspects related to sexual identification. GI in this test is defined as female (F), male (M) or ambiguous.Objective and hypotheses: To evaluate GI in patients with 46, XY DSD by the HTP test and compare th...

Background: Craniosynostosis, defined as the premature fusion of the cranial sutures, presents many challenges in aetiology. One known form associated to steroid biosynthesis impairment is the Antley-Bixler Syndrome (ABS). ABS-phenotype and normal steroidogenesis have FGFR mutations, whereas those with ambiguous genitalia and altered steroidogenes should be recognized as possibly having P450 oxidoreductase deficiency, with mild do moderate 17 OH progesterone (17HOP) elevation ...

Introduction: Individuals with ovotesticular disorders of sexual development (OT-DSD) have both seminiferous tubules and ovarian follicles. The combination of gonads could be separated (ovary-testis), unilateral (ovotestis-ovary or ovotestis-testis), or bilateral (ovotestis-ovotestis). The last one is the rarest variant (24.5%). In 60% of cases, the karyotype is 46, XX.Case Report: 15-year-old, monochorionic-monoamniotic...

Background: Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition which leads to glucocorticoid deficiency. During childhood, the main aims of treatment are to prevent adrenal crisis and to achieve normal stature, optimal adult height and to undergo normal puberty. In adults, the aims of treatment are to prevent adrenal crisis, ensure normal fertility and to avoid long-term consequences of glucocorticoid use. Current treatment regimens for CAH with glucocort...

Background: Severe primary deficiency of insulin-like growth factor-1 (IGFD) being characterized by growth failure and short stature in children, constitutes an indication to recombinant human IGF-1 (mecasermin) treatment. It is defined by serum insulin-like-growth factor-1 (IGF-1) levels less than or equal to 2.5 th percentile, height less than or equal to −3 S.D.S., normal growth hormone (GH) secretion and exlusion of secondary causes of IGFD.<p clas...

Background: SHOX encodes a transcription factor implicated in skeletal development. Approximately 70% and ~2.5% of Leri-Weill dyschondrosteosis (LWD) and idiopathic short stature (ISS) patients, respectively, have a defect in SHOX or its regulatory regions.Objective and hypotheses: i) To perform SHOX mutation screening in a cohort of 585 patients referred with a clinical suspicion of LWD or ISS. ii) To determine which is the <e...
