Vitamin D deficiency in pediatric population and influence on PTH levels

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...

Abdominal fat measured with nutritional ultrasound as a risk screening for non-alcoholic hepatic steatosis (NASH) in obese children

Diez-Lopez Ignacio , Sarasua-Miranda Ainhoa , Maeso Mendez Sandra , Garcia Casares Zuriñe , Erika Calvo Saez A

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...

Big data as a strategy in the development of population auxological studies

Diez-Lopez Ignacio , Maeso Mendez Sandra , Casado Tellechea Ioar , Lozano JA , Pérez Aritz

To date, knowledge of population dynamics and its repercussions on health required complex, long and expensive field studies. Big data tools are nowadays postulated as a tool of first magnitude for weighted population changes observed in real time if reliable sources of collection and adequate mathematical and computer tools for their assessment are available.Main Objective: Carry out a methodological approach to the use of big data appl...

Big data tools for assessing the nutritional situation of a pediatric population: did the prevalence of obesity change pre- and post-pandemic?

Diez-Lopez Ignacio , Maeso Mendez Sandra , A Lozano Jose , Casado Tellechea Ioar , Pérez Aritz

To date, knowledge of population dynamics and its repercussions on health required complex, long and expensive field studies. Big data tools are nowadays postulated as a tool of first magnitude for weighted population changes observed in real time if reliable sources of collection and adequate mathematical and computer tools for their assessment are available.Main Objective: To evaluate, using big data tools, whether there have been sign...

Influence of the Bacillus Calmette-Guérin vaccine on the incidence of cases of type 1 diabetes mellitus in children and adolescents in the Basque Country (last CCAA to withdraw vaccination in Spain)

Diez-Lopez Ignacio , Maeso Mendez Sandra , Gago Martin Ruth , Angel Ogueta Lana Miguel

Type 1 diabetes mellitus is a chronic disease of autoimmune etiology that is highly prevalent in childhood. In the last decade, the possibility of using the Bacillus Calmette-Guérin vaccine for the treatment of this disease has been studied thanks to its immunomodulatory action. These authors published a few years ago an inconclusive work on the influence of the use of BCG on the number of cases observed in the CCAA in a smaller cohort (Bol S Vasco- Nav Pediatrician 202...

Regulated sports activity is a greater protective factor for obesity than lunch at school, even in a pandemic.

Diez-Lopez Ignacio , Maeso Mendez Sandra , Rodriguez Quintana Arrate , Colaborativo Colegio San Prudencio Grupo

These authors published (Bol. S Vasco- Nav Pediatr 2016; 48: 12-16) the situation of this cohort is well characterized in relation to weight, regular school exercise and/or going to the school cafeteria. It was shown that, although the population was of a medium-high socioeconomic level, the overweight situation was lower among children with regular school exercise, with no evident influence between those exposed or not to the school cafeteria.Go...

Value of antimullerian hormone (AMH) in the diagnosis of precocious puberty: revaluation of the covid-19 post-pandemic cohort

Diez-Lopez Ignacio , Aurora Vilella San Martín Leyre , Sarasua Miranda Ainhoa , San Martin Orayen Amaia , Maeso Mendez Sandra

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)</...

Detection of risk of non-alcoholic hepatic steatosis (nash) in obese children's population through rapid ultrasound measurement of preperitoneral abdominal fat “at the bed side”. a new strategy

Diez-Lopez Ignacio , Maeso Mendez Sandra , Garcia Casares Zuriñe , Calvo Saez Erika , Santos Corraliza Erika , Gamarra Cabrerizo Ainara

NASH is an increasingly relevant finding in the pediatric population affected by obesity. In adults, the evolution of this steatosis towards fibrosis and correlation with metabolic syndrome is increasingly significant. The existence of a rapid and validated in-office screening tool would be very useful.Main Objective: To evaluate whether the measurement of intraperitoneal fat measured through nutritional ultrasound allows for the diagnos...
