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...

Background: Since the late 1960’s, pubertal breast staging has been based on Tanner’s classification. Appearance of glandular breast tissue may be difficult to distinguish by palpation from the surrounding subcutaneous fat tissue, especially in obese girls. To our knowledge, validation of the clinical assessment of pubertal stages by MRI quantification of glandular breast tissue has never been performed.Objective and hypotheses: i) To report no...

Background: Sexual maturation is closely linked to growth, suggesting common pathways between the reproductive development and the growth hormone/insulin-like growth factor-I (GH/IGF-I) axis. IGF-I bioavailability is regulated by Pregnancy associated plasma protein-A (PAPP-A), Pregnancy associated plasma protein-A2 (PAPP-A2) and Stanniocalcin 2 (STC2). A large genome-wide association study (GWAS) identified PAPP-A, PAPP-A2 and STC2 to represent loci strongly a...

Introduction: Klinefelter syndrome (KS) is most common sex chromosomal aneuploidy in males. The typical clinical features are tall stature with long extremities, small testis, and learning disabilities. Three M syndrome is an extremely rare genetic disorder characterized by short stature, craniofacial abnormality and skeletal malformations. We report a unique case of short stature in KS due to three M syndrome.Case: A 9-...

Background: Children conceived after assisted reproductive technology (ART) with frozen embryo transfer (FET) are more often born large-for-gestational age (LGA) while children born after fresh embryo transfer (fresh-ET) are at risk of being small-for-gestational age (SGA). LGA or SGA children are at increased risk of obesity, diabetes and cardiovascular disease later in life. The long-term cardio-metabolic health of children born after ART is scarcely explore...

Background: Obesity in childhood is defined by age- and sex-specific BMI cut-off values. However, BMI does not disclose the distribution of fat mass. Increased abdominal adipose tissue is associated with a higher risk of cardio-metabolic disease in adulthood. Thus, precise measurements of abdominal adipose tissue in children may enable early prevention of disease.Objective and hypotheses: To validate measurements of abdominal adipose tissue by anthropome...

Objective: To accumulate the information in the long-term studies of the variation of the limb segments length and proportion in the process of growth and development of children, we have measured and summarized the average level of limb segments length for the children and adolescents in the main urban area of Chongqing, calculated the ratios of limb segments length to height and extremities-trunk ratio, body proportions, and analyze their age trends.Me...

Background: Primary ovarian insufficiency (POI) is genetically mediated in up to 30% of cases. Many genes associated with POI have roles in early ovary developmental processes, including meiosis.Objectives: We investigated the genetic mechanism underlying early-onset POI in three young women presenting with absent puberty: two sisters from a consanguineous pedigree and a third unrelated proband.<st...

Introduction: PMM2-CDG is the most common congenital disorder of glycosylation (CDG). Since glycoproteins are involved in every endocrine axis, PMM2-CDG patients have a high risk of developing endocrinopathies.Case report: We describe two 12 years-old female PMM2-CDG patients with severe short stature and no clinical sign of puberty. One patient showed low serum levels of insulin-like growth factor-1 (IGF-1) and IGF bind...

Introduction: High doses of biotin are reported to cause incorrect results in various immunoassays in some patients. However, there is no systematic study regarding biotin interference in childhood.Aim: To assess thyroid function with different methods in subjects with biotinidase deficiency, to determine the factors causing interference, and to investigate the efficiency of the methods for overcoming interference.Method: The study...
