The Severity of Congenital Hypothyroidism With Gland-In-Situ Predicts Molecular Yield by Targeted Next-Generation Sequencing.

Introduction: Congenital hypothyroidism with gland-in-situ (CH-GIS) is usually attributed to mutations in the genes involved in thyroid hormone production. The diagnostic yield of targeted next-generation sequencing (NGS) varied widely between studies. We hypothesized that the molecular yield of targeted NGS would depend on the severity of CH.

Bariatric surgery in adolescents with severe obesity: Review and state of the art in France.

Severe obesity (body mass index>120% of BMI IOTF-30 cut off) and morbid obesity (BMI>140% of BMI IOTF-30 cut off) affect 5 to 10% of obese adolescents in France. Organic complications can be found in about 50% of these patients, and depressive symptoms in one-third of them. Finally, over 70% will suffer from adult morbid obesity associated with a marked increase in morbidity and mortality.

How to investigate a child with excessive growth?

The diagnostic approach to tall stature in children is based on collecting birth data (macrosomia), sizes and family puberty, a family history of constitutional or pathological tall stature, search for a delay of development, dysmorphia, disproportion, analysis of the growth velocity (normal or accelerated), general examination and assessment of puberty, and bone age. When there is a history of psychomotor retardation, a family history of pathological tall stature, or a disproportion in the clinical examination, the genetic causes of tall stature will be mentioned. The most frequent causes are Marfan syndrome and similar, Sotos syndrome, Beckwith-Wiedemann syndrome, Klinefelter syndrome, and MEN2B.

Birth Weight Is Associated With the IGF-1 Response to GH in Children: Programming of the Anabolic Action of GH?

Context: Intrauterine programming of the somatotropic axis has been hypothesized in cases of intrauterine growth retardation.

Objective: The objective of the study was to study the effects of birth weight and body composition on GH sensitivity.

Design: This was a cross-sectional study with a single GH administration to assess GH sensitivity.

Diagnosis and management of congenital hypothyroidism associated with pseudohypoparathyroidism.

Unlabelled: Hypothyroidism is a particular condition observed in pseudohypoparathyroidism (PHP), a rare disorder characterized by parathyroid (PTH) resistance leading to hypocalcemia and hyperphosphatemia associated with a GNAS (guanine nucleotide-binding protein α-subunit) mutation (PHP1A) or epimutation (PHP1B). To determine the presence of hypothyroidism at birth we conducted a retrospective study in our cohort of patients presenting with either PHP1A (n = 116) or PHP1B (n = 99). We also investigated patients presenting at birth with congenital hypothyroidism (CH) and a eutopic thyroid gland for phosphocalcium abnormalities suggesting PTH resistance and PHP.
