Background: Congenital hypothyroidism (CH) is a common endocrine disorder with a prevalence ranging from 1:2000 to 1:4000 newborns. The majority of CH cases were reported to be associated with mutations in several genes, which including the TSH receptor gene (TSHR).Objective and hypotheses: The aim of this study is to examine the frequency of TSHR gene mutations among CH patients in the Guangxi Zhuang Autonomous Region of China and to discover correlatio...

Introduction: Primary Congenital Hypothyroidism (CH) is an abnormal function of the thyroid gland present at birth. Anomalies of thyroid function are usually classified between thyroid dysgenesis, corresponding to an abnormal embryological development of the thyroid, and CH with gland-in-situ (GIS), resulting from mutations in genes involved in thyroid hormone synthesis. We report 105 patients with CH with GIS that have been referred to Angers University Hospi...

Introduction: The underlying genetic causes of congenital hypothyroidism with gland in-situ (CH GIS) and hyperthyrotropinemia (HT) remain largely a mystery. Thanks to NGS, genetic screening is now finding many novel variants. The challenge is to correctly identify which genes and which variants lead to CH and which cause only a transient HT.Objectives: Our objectives were to evaluate the presence of variants in 14 candid...

Background: Congenital hypothyroidism (CH) is an important and preventable cause of growth retardation and neurological deficit. Early treatment is crucial to minimize long term effects and today regimens tend to be more aggressive targeting hormonal control.Objective: To correlate CH severity at diagnosis with levothyroxine (LT) dosage and time needed to control TSH levels.Methods: Retrospective study including children with CH at...

Background: Central hypothyroidism (CH) is caused by TSH and/or TRH deficiency leading to hypothyroxinemia with low, normal or mildly elevated TSH levels. Differentiation of CH with mildly elevated TSH levels from primary hypothyroidism (PH) can be difficult. However, this differentiation has important clinical implications (i.e. cortisol replacement before L-thyroxine).Objective and hypotheses: In this study, we constructed a nomogram all...

Background: An increased prevalence of extra-thyroidal congenital malformations in infants with congenital hypothyroidism (CH) is well established. However, accurate estimation of prevalence figures requires careful distinction between permanent and transient CH. Moreover, the mechanisms resulting in congenital malformations are not well understood.Study aim: To estimate the prevalence of cardiac, extra-cardiac and/or sy...

Introduction: Carbohydrate restriction (CH-R) in adolescents with obesity results in faster BMI reduction and glucose metabolism improvement than diets with normal carbohydrate proportion, without a higher weight regain in the short term. However, data on weight and metabolic trajectories of these patients after a more prolonged follow-up are sparse.Objectives: To evaluate metabolic and body composition evolution during ...

Congenital hypothyroidism (CH) occurs in approximately 1:2,000 to 1:4,000 newborns, in Algeria newborn screening programs do not exist, untreated CH remains a significant health and societal challenge. We report the case of a girl of 12 years old reffered for a failure to thrive, speech deficit and persistant vomiting, On clinical examination her height was –3 SDs with a very delayed bone age and a BMI of 35kg/m2 associated with severe musculoskeletal deformities and cog...

Background: Identification of Congenital Hypothyroidism (CH) is an essential part of Newborn Bloodspot Screening (NBS) in the UK. NBS for CH relies on Blood Spot (BS) Thyroid Stimulating Hormone (TSH) measurement in newborns on day 5 of life. Diagnostic confirmation of a screen positive result requires measurement of plasma/serum free thyroxine (fT4) and TSH but technetium thyroid scanning is not mandatory. Technetium-99m scintigraphy can be used to define siz...

Background: Dietary carbohydrate restriction in the treatment of obese adolescents could cause a substantial shift in the substrates used as an energy source, inducing changes on body composition and metabolism, but experience in this age range is limited.Objective: We assessed the influence of 6 months of dietary carbohydrate restriction on body composition and lipid and carbohydrate metabolism in obese adolescents.Method: Thirty-...
