Diez-Lopez Ignacio , Sarasua Miranda Ainhoa , Maeso Mendez Sandra

Transversal study. Patients from 0 to 17 years of age who had undergone an analytical determination of 25OHD during the year 2021 in our hospital were collected. The following were contrasted: 25OHD, PTH, total calcium, age, sex, reason for requesting analysis, time of year and country of origin. 25OHD ranges: normal >30 ng/mL, suboptimal 20-30 ng/mL and deficit <20 ng/mL; and normal PTH: 9-60 pg/mL.Results: 1. Prevalence of vitami...

NASH is an increasingly relevant finding in the pediatric population affected by obesity. In adults, its evolution from this steatosis to fibrosis and its correlation with metabolic syndrome is increasingly significant. The existence of a rapid and validated screening tool in consultation would be very useful.Main objective: To evaluate if the measurement of intraperitoneal fat measured through nutritional ultrasound, allows the diagnosi...

During the pandemic, an increase in the cases of premature thelarche consultations was observed. Our group published a series in 2021 of 75 cases. This effect could have been caused by an increase in body fat mass in girls, suggesting a “trigger effect” in the activation of the gonadal axis, causing an increase in the number of cases of early puberty (SEEP Oviedo 2022). AMH has been correlated as a predictor of the moment of menarche (doi: 10.1515/jpem-2014-0521)</...
