Meningococcal meningitis (MM) and invasive meningococcal disease remain a major public health problem that generates enormous public alarm. It is caused by Neisseria meningitidis, a Gram-negative diplococcus with an enormous capacity for acute and rapidly progressive disease, both episodic and epidemic in nature, with early diagnosis and treatment playing a major role. It occurs at any age, but is most common in children under 5 years of age followed by adolescents. Although most cases occur in healthy people, the incidence is higher in certain risk groups. Despite advances in reducing the incidence, it is estimated that in 2017 there were around 5 million new cases of MM worldwide, causing approximately 290,000 deaths and a cumulative loss of about 20,000,000 years of healthy life. In Spain, in the 2021/22 season, 108 microbiologically confirmed cases of MM were reported, corresponding to an incidence rate of 0.23 cases per 100,000 inhabitants. This is a curable and, above all, vaccine-preventable disease, for which the World Health Organisation has drawn up a roadmap with the aim of reducing mortality and sequelae by 2030. For all these reasons, the Illustrious Official College of Physicians of Madrid (ICOMEM) and the Medical Associations of 8 other provinces of Spain, have prepared this opinion document on the situation of MM in Spain and the resources and preparation for the fight against it in our country. The COVID-19 and Emerging Pathogens Committee of ICOMEM has invited experts in the field to participate in the elaboration of this document., (©The Author 2024.

Hypertransaminasemia is a frequent finding in pediatrics, which could reflect potentially treatable serious disease. The aim of this document is to establish, by reviewing the available evidence, a consensus for an adequate management of hypertransaminasemia, from its detection until the study is complete. To this end, a working group was formed with the participation of members of the Society of Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP), the Spanish Association of Primary Care Pediatrics (AEPap) and the Spanish Society of Primary Care Pediatrics (SEPEAP). Twenty-one recommendations are established with a marked practical component that will be useful in hospital clinical practice and primary care., (Copyright © 2022 Asociación Española de Pediatría.

Non-IgE-mediated cow's milk allergy is a frequent disorder in paediatrics. As patients might be seen by professionals from different specialties and levels of expertise, a great variability in diagnostic procedures and disease monitoring is commonly observed. Therefore, four scientific societies involved in its management have developed a consensus document providing specific recommendations related to its prevention, diagnosis, treatment and follow up., (Copyright © 2019 Asociación Española de Pediatría.

Introduction: the recent economic and financial crisis has affected most Western countries, especially families of low socioeconomic classes. We speculate that worsening of socioeconomic condition associated with the crisis would increase obesity, mainly in disadvantaged families., Material and Methods: cross-sectional study of the 290,111 children aged three to 12 years old attending public school during the term 2014-2015 in Madrid City, by means of a stratified weighted sample randomly chosen, taking into account age (grade), city district and schools. The questionnaire included weight and height (auto-reported), dietary report (weekly frequency of intake), as well as socioeconomic variables., Results: 1,208 questionnaires were evaluated from 64 classes. Half of participants were boys; 42% were younger than five years old, 35% werebetween six and eight years old, and 23% older than eight. Undernutrition was present in 5.0%, and excess of weight (overweight + obesity) in 36.7%. Undernutrition was higher in children under the age of six (9.1%). No relationship was found between undernutrition and the characteristics of the families but was slightly higher in families where both parents were unemployed. Excess of weight was higher in children of non-Spaniard parents (44% vs 32%, p < 0.0001), as well as in those families with economic problems (41% vs 31%, p = 0.0005). Only for meat, grains and dairy, the weekly intake was close to the recommendations., Conclusions: children from lower income households were at a higher risk of being overweight compared with their peers. Participation in a school-based food aid program may reduce food insecurity for children and their families.

Objective: Recent studies in adults have shown that hemorrheological alterations are predictive of early cardiovascular disease, but it is unknown if they are related to hyperlipemia or are secondary to an established atherosclerotic process and if they appear during childhood., Patients and Methods: Several rheological parameters have been studied in 36 patients with familial hypercholesterolemia (FH). These patients were between 2 and 16 years of age and 12 of them were being treated with cholestyramine. Thirty-five controls (CG) were individually matched for age and sex., Results: The FH patients treated with cholestyramine did not show significant differences in any of the six rheological parameters that were studied when compared to the other patients. Therefore, the results of the FH group were analyzed as a whole when they were compared with the CG. The following significant differences were found: Index of erythrocyte aggregation at stasis 5.0 +/- 1.2 vs 3.6 +/- 1.0 (p < 0.001), index of erythrocyte aggregation at low rate of blood shears 8.1 +/- 1.7 vs 6.9 +/- 1.4 (p < 0.001) and plasma viscosity 1.19 +/- 0.11 vs 1.16 +/- 0.04 mPA/s (p < 0.01). There were no significant differences in the plasma fibrinogen nor in the blood viscosity at shear rats of 230/s and 23/s. Carotic echo-doppler was taken in the HF patients which was normal, indicative of the absence of atherosclerosis lesions in the fibrous plaque phase., Conclusions: These results indicate that there are hemorrheological alterations in absences of established atherosclerotic lesions, which are associated with hypercholesterolemia and that emerge in the pediatric population. Therefore, research in FH patients offers new data to evaluate the atherogenic risk and its complications.
