Pediatric Hyperthyroidism in the Time of COVID-19: An Updated Presentation Analysis

Sol Ventura Paula , Gonzalez Alba , Valls Aina , Murillo Marta

Abstract: The SARS-CoV-2 virus uses ACE2 combined with the transmembrane-protease TMPRSS2 to enter and infect thyroid follicular cells. Studies have reported a higher incidence of hyperthyroidism cases during the COVID-19 pandemic compared to pre-pandemic periods. Studies have also been reported cases of thyroid dysfunction early after mass covid vaccinations. However, there are insufficient data to confirm these associations in children.<p class="abstext"...

Evaluation of new cutt-off points of the LHRH stimulation test in the diagnosis of central precocious puberty

Valls Llussà Aina , Murillo Vallés Marta , Martinez Couselo Silvia , Sol Ventura Paula

Introduction: Central precocious puberty (PPC) is defined by the appearance of sexual characters at a chronological age lower than -2.5DS of the average for the reference population. Diagnostic is clinical but the hormonal assessment is essential. Basal gonadotropin values are not enough for the diagnosis. Gonadotropin-releasing hormone (GnRH) stimulation tests evidence the activation of the hypothalamic-pituitary-gonadal axis, however there is controversy abo...

The diagnosis of early thelarche is common in Pediatric Endocrinology consultations, with many cases lacking an organic cause. It can either spontaneously resolve, remain stable, or progress to precocious puberty. Early exposure to endocrine-disrupting environmental pollutants (EDs) with estrogenic and/or anti-androgenic effects during pregnancy or childhood may affect the timing of thelarche onset and/or puberty in girls. Further research is needed to better understand the in...
