Background: Neonatal screening strategies revealed an increase in hypothyroidism associated with an in-situ thyroid gland due to TSH receptor (TSHR) mutations. While there are many genetic and functional studies regarding TSHR mutations, few are found concerning the clinical course and long-term outcome of TSH resistance involving the pediatric population.Objective and hypotheses: To determine the impact of TSHR mutations on clinical course, biochemical ...

Background: At present, literature regarding postnatal growth in small for gestational age (SGA) subjects and itsÂ’ correlation with growth factor levels is still controversial. A relation between IGF1 and IGFBP3 levels at birth and weight and length catch up growth has been demonstrated. In the first months of life a rapid weight catch-up growth has also been associated to an increase of leptin, basal insulin and insulin resistance.Objective and hyp...

Background: Peutz-Jeghers syndrome (PJS) is a rare autosomal-dominant disorder frequently caused by the serine-threonine-kinase-11(STK11) gene mutation and characterized by hamartomatous polyps throughout the gastrointestinal tract, mucocutaneous hyperpigmentation and predisposition to several malignancies. Rarely, PJS may be associated to an oestrogen producing large cell calcifying Sertoli cell tumour that may result in gynecomastia and increased growth velocity (GV).<p ...
