Anaphylaxis management: knowledge of Brazilian pediatricians.

Objective: To verify the level of knowledge of Brazilian pediatricians about anaphylaxis, identifying sociodemographic and educational characteristics of the professional which contribute to the adequate management of this clinical disorder.

Methods: A survey was carried out on the management of anaphylaxis using a questionnaire prepared and distributed by email to pediatricians in different states in Brazil. The level of knowledge about anaphylaxis was classified as: satisfactory; unsatisfactory; more than satisfactory; ideal, according to evaluation criteria adopted for the statements of clinical cases that addressed the drug of choice, route of administration, positioning of the patient with anaphylaxis and recognition of the clinical case with differential diagnosis.

Avoidance of Inhaled Pollutants and Irritants in Asthma from a Salutogenic Perspective.

Much is known about the role of aeroallergens in asthma, but little is described about the damage caused by inhaled pollutants and irritants to the respiratory epithelium. In this context, the most frequent pollutants and irritants inhaled in the home environment were identified, describing the possible repercussions that may occur in the respiratory tract of the pediatric population with asthma and highlighting the role of the caregiver in environmental control through a salutogenic perspective. Searches were carried out in the MEDLINE/PubMed, Web of Science, Lilacs and Scopus databases for articles considered relevant for the theoretical foundation of this integrative review, in which interactions between exposure to pollutants and inhaled irritants and lung involvement.

Heart rate variability in school-age children born moderate-to-late preterm.

Background: Prematurity is associated with reduced cardiac autonomic function. This study aimed to investigate the heart rate variability (HRV) in school-age children born moderately to late preterm (MLPT).

Methods: This cross-sectional study investigated school-age children, aged 5 to 10 years, born moderate-to-late preterm.

Respiratory allergy symptoms and cytokine profiles in the presence of anti-Ascaris antibody in Giardia lamblia-infected children.

Anti-Ascaris lumbricoides (Asc) IgE and IgG can immunomodulate the allergy; however, the influence of these isotypes has not been investigated in the giardiasis and allergy. Therefore, the frequency of respiratory allergy (RA) symptoms in Giardia lamblia-infected children, with or without anti-Asc IgE, IgG1, or IgG4 and Th1, Th2/Treg, and Th17 cytokine production, was evaluated. We performed a case-control study with children aged 2-10 years old selected by questionnaire and stool exams to form the groups: infected or uninfected with RA (G-RA, n = 55; nG-RA, n = 43); infected and uninfected without RA (G-nRA, n = 59; nG-nRA, n = 54).
