Introduction: McCune Albright Syndrome consists of at least 2 of the following 3 features: (1) polyostotic fibrous dysplasia (PFD), (2) Café au lait macules and (3) autonomous endocrine hyperfunction (eg, gonadotropin-independent precocious puberty). Other endocrine syndromes include hyperthyroidism, acromegaly, and Cushing syndrome.Case: 2 year old girl presented with severe hip pain, inability to walk and progressive deformity of right lower limb....

Background/Aims: 46,XY gonadal dysgenesis (GD) is classified as complete (CGD) or partial (PGD) depending on gonadal morphology and function. In contrast to the typical female external genitalia in CGD, the phenotype of PGD is variable depending on androgen production. A diagnosis of PGD is based on clinical/biochemical features, gonadal histology and genetic findings. The aim of this study is to characterise these features, particularly histological, in a lar...

Background: overexpression of the oncogene Yes-associated protein 1 (YAP1), a Hippo pathway target, associates with increased cell proliferation in some human cancers. There is not data on adrenocortical tumors (ACT). YAP1 is a potential target of Wnt/β-catenin pathway, which plays an important role in ACTs.Objective and hypotheses: to evaluate the role of YAP1 and its interaction with the Wnt/β-catenin pathway in ACT.Met...

Background: There is limited data supporting concerns that systemic corticosteroids, prescribed in pregnancy for maternal health reasons, can suppress the neonatal Hypothalamic-Pituitary-Adrenal (HPA) axis. Our study aimed to determine if neonates born to mothers on long-term or high dose steroids are at risk of adrenal suppression.Methodology: Neonates who underwent assessment of adrenal function over a seven-year perio...

Introduction: Following the onset of the COVID-19 pandemic in spring 2020, the European Registries For Rare Endocrine Conditions (EuRRECa), which is a collaboration between Endo-ERN, ESPE and ESE provided the possibility for registration of cases. Obesity is a risk factor for severe COVID-19 disease course in adults. In children and adolescents, COVID-19 disease course is much milder, but has also been identified as risk factor. As rare genetic obesity disorde...

Background: To update the ongoing debate about the use of universal strict vs (local) national intrauterine growth charts, we compared the prevalence of small and large-for-gestational-age (SGA/LGA) infants according to international charts and national growth data.Methods: We classified singleton births from 33 to 42 weeks of gestation in 2016 and 2019 from Qatar (n = 92431), SGA (birthweight <10th percentil...

Introduction: Infants whose weight is > the 90th percentile for gestational age are classified as large for gestational age (LGA). Catch-up and catch-down growth can be defined as an increase or decrease in WAZ by > 0.67 SD respectively during the infantile period. It was suggested that in LGA rapid catch-up and/or no catch-down during infancy may be associated with the development of overweight (OW) and obesity (OB) during childhood.<p class="abstex...

Introduction: Large for date (LGA) infants may have a higher tendency to become obese and tall. Catch-up and/or catch-down in linear growth, defined as an increase or decrease in length for age Z score (LAZ) by > 0.67 SD during the infantile period, may affect this tendency. Additionally, head circumference is well correlated with brain growth.Aim: We evaluated the prevalence of tall stature (LAZ > 1 and> 2) and...

Introduction: Urinary gonadotrophins measurement is a noninvasive method for evaluation of pubertal development and may have utility in population studies.Objectives: To investigate the utility of urinary gonadotrophins as a noninvasive biomarker of puberty in boys and girls.Methods: School-based adolescent cohort study with two time points for collecting school time urine samples ...

Introduction: Congenital lipoid adrenal hyperplasia (lipoid CAH), is a rare subtypes of adrenal hyperplasia yet the most fatal form, which seriously disrupts adrenal and gonadal steroidogenesis by a defect in the conversion of cholesterol to pregnenolone. Affected patients show salt loss from impaired mineralocorticoid and glucocorticoid synthesis. The defect in lipoid CAH is mainly in the steroidogenic acute regulatory protein (StAR), which promotes entry of ...
