Background: Disorders of sex development (DSD) comprises a heterogeneous group of conditions involving interference with normal sex differentiation and hormonal production in the embryo. Imaging is a very useful tool in assessing the patient’s phenotypic sex through identifying the internal genital anatomy and the adrenal glands. Ultrasonography is a cheap and readily available tool. MRI has disadvantage of being expensive with long waiting lists especially in developin...

Background: Gonadotropin independent precocious puberty (GIPP) is caused by a heterogenous group of disorders. With the exception of congenital adrenal hyperplasia (CAH), disorders causing GIPP are uncommon, and there are no studies evaluating the etiologic distribution of GIPP in a large cohort.Objective and hypotheses: To find out the relative frequencies of each etiological group in patients with non-CAH GIPP and also to evaluate the clinical and labo...

Background: Severe primary insulin-growth factor-1 (IGF-1) deficiency (SPIGF1D) is a rare cause of growth retardation. Diagnostic criteria include age- and sex-dependent low basal IGF-1 levels (<2.5th percentile), height ≤ -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: Description of pubertal onset and growth spurt, data on adult or near-adult-he...

Background: Turner syndrome (TS) can manifest with various clinical features depending on the karyotype and the genetic background of affected subjects.Objective and hypotheses: The aim of this study was to evaluate growth parameters from birth to adulthood in girls with TS in a cross-sectional study.Method: A total of 842 patients, with an age of diagnosis ranging from birth to 18 years followed-up between 1984 and 2014, from 35 d...

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: Melanocortin 4 receptor (MC4R) deficiency is the commonest monogenic form of non-syndromic obesity. MC4R is a seven transmembrane G-protein coupled receptor implicated in central regulation of body weight. The loss-of-function mutations in MC4R gene will contribute to early-onset obesity associated with hyperinsulinemia, hyperphagia and “binge eating”. We aim to determine the prevalence of MC4R variants in a Pediatrics...

Background: Transient hypothyroxinaemia of prematurity (THOP), defined as low levels of FT4 without the expected TSH surge, may concern up to 50% of infants born <30 weeks’ gestational age. Most studies showed a link between THOP and impaired neurodevelopment, as shown in the review of Eerdekens. Data about the benefit of supplementation are scarce, with few randomised trials and inconclusive results. To date, there are no clear recommendations regard...

Aim: Increased clinical attention toward less severe cases of congenital adrenal hyperplasia (CAH) may affect both incidence and prevalence. In this nationwide population-based cohort study, we estimate incidence, prevalence, and age at diagnosis of CAH according to subtype and sex.Patients and Methods: Individuals registered with a diagnosis of CAH during 1977 to 2018 were identified in the Danish National Patient Regis...

Craniopharyngioma is a rare, embryonic malformation of the sellar/parasellar region with low histological grade. In childhood-onset craniopharyngioma (CoCR), endocrine dysfunctions, severe obesity and metabolic syndrome (MetS), neurological impairment and reduced quality of life have been described as consequences of both localization and treatment. To characterize a population with CoCR and to correlate endocrine/metabolic sequelae with different surgery approach we performed...

Background: Disorder of sex development (DSD) includes a wide spectrum of clinical disorders affecting gonadal and genital development. Many causative gene mutations are involved in these disorders. One of these genes is nuclear receptor subfamily 5 group A member 1 (NR5A1) encoding Steroidogenic factor-1 (SF-1) located on chr 9q33.3. This gene is expressed in many tissues such as Sertoli cell and Leydig cell in testes, ovaries, placenta, adrenal cortex, hypot...
