Article Synopsis
- The study looked at poisoning cases in kids under 16 in Mexico from 2016 to 2020.
- There were 459 cases of poisoning, mostly from venomous animals and medications, and most incidents were accidental.
- Younger kids were mainly poisoned by household products, while older kids were more affected by stimulant drugs.
Introduction: It is unknown whether late adolescents represent a particular risk group for the development of red meat hypersensitivity (RMH) and alpha-gal syndrome (AGS). This age group's physiological changes and eating habits could play a determining role. This study aimed to estimate the self-reported prevalence of RMH and probable AGS among late adolescents.

Methods: A cross-sectional analysis of the epidemiological surveillance system dataset for respiratory diseases in Mexico carried on. From 27 February to 5 November 2020, a total of 1,048,576 subjects were screened for SARS-CoV2 infection, of which 35,899 were children under 18 years of age.
Objective: To determine the prevalence of cow´s milk allergy and lactose intolerance in a sample of late adolescents.
Methods: Through a population-based study, data corresponding to students with aged 15 to 18 years were analyzed.
Results: A total of 1992 adolescents was analized.
Article Synopsis
- The study focuses on how comorbidities affect the risk of symptomatic SARS-CoV-2 infection and Pediatric Inflammatory Multisystemic Syndrome (PIMS) in children.
- Out of 375 pediatric patients analyzed, nearly 48% had comorbidities, with obesity being a significant risk factor for infection, while cancer patients were less likely to develop PIMS.
- The results suggest that underlying health conditions can change the likelihood of severe outcomes from COVID-19 in children.
The main expected result of a vaccine against viruses is the ability to produce neutralizing antibodies. Currently, several vaccines against SARS-CoV-2 are being applied to prevent mortal complications, being Pfizer-BioNTech (BNT162b2) one of the first to be authorized in the USA and Mexico (11 December 2020). This study evaluated the efficacy of this vaccine on antibody production with neutralizing capacity and its side effects in healthcare workers with and without prior SARS-CoV-2 infection and in a group of unvaccinated individuals with prior COVID-19.

Background: It has recently been argued that asthma does not increase the risk of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. If so, the prevalence of asthma in subjects diagnosed with COVID-19 should be lower than in the general population.
Objective: To determine the prevalence of asthma in Mexican children and adults with SARS-CoV-2 infection.
Background: The relationship between birth by cesarean section (CS) and allergic diseases' prevalence continues to be controversial. We aimed to investigate if being born by CS is associated with the prevalence of allergic diseases and their symptoms in schoolchildren.
Methods: This study included children between 6 and 7 years of age, selected by population-based sampling.
Article Synopsis
- The study categorize oral allergy syndrome (OAS) into two phenotypes: phenotype I caused by plant-derived foods and phenotype II caused by both plant and animal foods.
- A cross-sectional analysis of 1,992 teenagers aged 15-18 revealed an overall OAS prevalence of 1.7%, with both phenotypes appearing at a frequency of 0.85%.
- Symptoms varied by phenotype, with gastrointestinal issues like diarrhea more common in phenotype II, while the onset of symptoms showed some association with the phenotype type.
Background: In Mexico, there are very few studies aimed at establishing the prevalence of allergic rhinitis (AR) and atopic dermatitis (AD) in late adolescents.
Objective: To determine the prevalence of allergic rhinitis and atopic dermatitis in late adolescents and compare it according to their gender.
Methods: A cross-sectional study that included 1992 15 to 18 year old adolescents who were recruited through a stratified and randomized probabilistic sample by clusters.
Introduction: The association regarding the exposure to pets, especially cats and dogs, and the prevalence of allergic diseases is inconsistent.
Objective: We analyzed the role played by early exposure to dogs or cats in the prevalence of allergic diseases amongst school-aged children.
Method: Through a cross-sectional study, we examined 756 children, aged 6-7; these candidates were selected through cluster sampling.
Introduction: The commonly held notion that a rural environment decreases the frequency of allergic diseases has proven to be inconsistent amongst children.
Objective: Our objective was to contrast the prevalence of bronchial asthma (BA), allergic rhinitis (AR), and atopic dermatitis (AD) between children that live in a rural environment and those that live in urban areas.
Methods: We carried out a cross-sectional study amongst children aged six to seven; they were selected through probabilistic, stratified and conglomerated sampling.
