RESUMEN
Drug hypersensitivity reactions (DHR) in children have a significant impact on clinical practice and public health. Both under-diagnosis (due to under-reporting) and over-diagnosis (due to the overuse of the term "allergy") are potential issues. The aim of this narrative review is to describe the most recent findings of DHR in children/adolescents and gaps regarding epidemiology, antibiotic allergy, antiepileptic hypersensitivity, vaccine allergy, and severe cutaneous adverse reactions (SCAR) in this age group.
RESUMEN
Biological particles, along with inorganic gaseous and particulate pollutants, constitute an ever-present component of the atmosphere and surfaces. Among these particles are fungal species colonizing almost all ecosystems, including the human body. Although inoffensive to most people, fungi can be responsible for several health problems, such as allergic fungal diseases and fungal infections. Worldwide fungal disease incidence is increasing, with new emerging fungal diseases appearing yearly. Reasons for this increase are the expansion of life expectancy, the number of immunocompromised patients (immunosuppressive treatments for transplantation, autoimmune diseases, and immunodeficiency diseases), the number of uncontrolled underlying conditions (e.g., diabetes mellitus), and the misusage of medication (e.g., corticosteroids and broad-spectrum antibiotics). Managing fungal diseases is challenging; only four classes of antifungal drugs are available, resistance to these drugs is increasing, and no vaccines have been approved. The present work reviews the implications of fungal particles in human health from allergic diseases (i.e., allergic bronchopulmonary aspergillosis, severe asthma with fungal sensitization, thunderstorm asthma, allergic fungal rhinosinusitis, and occupational lung diseases) to infections (i.e., superficial, subcutaneous, and systemic infections). Topics such as the etiological agent, risk factors, clinical manifestations, diagnosis, and treatment will be revised to improve the knowledge of this growing health concern.
RESUMEN
Nas últimas décadas tem se observado um aumento expressivo na prevalência de alergia alimentar (AA), com frequência estimada em adultos de 3% a 8%, sendo ainda mais relevante quando se avalia a AA autodeclarada (variação de 3% a 35%). Entretanto, são poucos os dados publicados sobre a prevalência de AA em idosos, e no Brasil tais dados são inexistentes. O objetivo principal deste protocolo de estudo é conhecer a prevalência de AA autodeclarada em idosos (≥ 60 anos) brasileiros. Trata-se de estudo epidemiológico transversal que utiliza questionário padronizado e validado para a língua portuguesa. Entre os vários aspectos investigados, serão avaliados quais alimentos e sintomas são os mais relacionados à AA nestes indivíduos. Os dados obtidos serão transcritos a planilha Excel para realização da análise estatística. A obtenção dessas informações permitirá compará-las às existentes, assim como estabelecer planos de abordagem destes pacientes.
In recent decades, there has been a significant increase in the prevalence of food allergies, reaching an estimated frequency of 3% to 8% in adults and even higher in self-reports (from 3% to 35%). However, published data on the prevalence of food allergies among older adults are scarce, and in Brazil they are non-existent. The main objective of this study was to investigate the prevalence of self-reported food allergy among older Brazilians (≥ 60 years). This cross-sectional epidemiological study protocol involves a questionnaire that was developed, standardized, and validated in Portuguese. The investigated aspects will include the foods and symptoms most commonly associated with food allergy in this population. The data will be input into an Excel spreadsheet for statistical analysis. Obtaining this data will allow comparison of the results with previous data and help establish treatment plans for these patients.

INTRODUCTION: Although the prevalence of allergic diseases, including food allergies, has increased over recent decades, relevant information on this topic is still lacking, particularly in younger children living in small cities. OBJECTIVE: To investigate the prevalence of reported food allergies in preschoolers in Limoeiro/Pernambuco, Brazil. METHODS: This was a cross-sectional study with preschoolers. Parents/guardians of all preschoolers enrolled at municipal schools between March and June 2019 (total of 619) were invited to complete a screening questionnaire (total of 619). Another 151 questionnaires were applied on the streets of the town. For positive responses, a second, more detailed and validated questionnaire was completed. RESULTS: A total of 412 questionnaires were returned, of which, 47 presented a positive response to food allergies and only 29 (7.04%) identified a particular food. The most frequently reported food items were shrimp, mollusks, pork, fruit and milk. Of the 29 who identified foods, 22 responded to the detailed questionnaire, resulting in only 4 (0.97%) positive responses. Of these, two were later discarded through clinical examinations and an open oral provocation test, resulting in a final prevalence of 0.48% of confirmed food allergies. CONCLUSION: The prevalence of reported food allergies was lower than that described in previous studies. The most commonly mentioned foods were shrimp, mollusks and pork, with more reports of multiple food allergies, even in children who had never been previously exposed to these possible allergens, which highlights the relevance of perception in reported food allergy studies.

Asthma is the most frequent chronic condition in childhood and a current concern exists about asthma in the pediatric population and its risk for severe SARS-CoV-2 infection. Although all ages can be affected, SARS-CoV-2 infection has lower clinical impact on children and adolescents than on adults. Fever, cough and shortness of breath are the most common symptoms and signs in children; wheezing has not been frequently reported. Published studies suggest that children with asthma do not appear to be disproportionately more affected by COVID-19. This hypothesis raises two issues: is asthma (and/or atopy) an independent protective factor for COVID-19? If yes, why? Explanations for this could include the lower IFN-α production, protective role of eosinophils in the airway, and antiviral and immunomodulatory proprieties of inhaled steroids. Additionally, recent evidence supports that allergic sensitization is inversely related to ACE2 expression. Obesity is a known risk factor for COVID-19 in adults. However, in the childhood asthma-obesity phenotype, the classic atopic Th2 pattern seems to predominate, which could hypothetically be a protective factor for severe SARS-CoV-2 infection in children with both conditions. Finally, the return to school activities raises concerns, as asymptomatic children could act as vectors for the spread of the disease. Although this is still a controversial topic, the identification and management of asymptomatic children is an important approach during the SARS-CoV-2 epidemic. Focus on asthma control, risk stratification, and medication adherence will be essential to allow children with asthma to return safely to school.

INTRODUCTION: Prevalence of diseases associated with ageing is rising; among these are the rhinologic problems. Chronic rhinitis appears as one of the most common worrisome nasal disorders in this age group. At the same time, the allergic form diminishes because of the immunosenescence. OBJECTIVE: This study aimed to evaluate the effect of a corticosteroid nasal spray (mometasone furoate) over nasal patency and the severity of rhinitis and its impacts on quality of life as compared with the saline nasal spray. METHODS: This open label-trial randomized subjects ≥60y with chronic rhinitis (allergic and nonallergic rhinitis) with mometasone spray 100mcg/d and isotonic saline nasal spray or saline alone for two weeks. The primary endpoint was the improvement in nasal patency evaluated by the peak nasal inspiratory flow (PNIF). Secondary outcomes included the severity of symptoms and the quality of life assessed by a visual analogic scale (VAS) and the sinonasal outcome test (SNOT-22), respectively. RESULTS: Forty patients underwent randomization, in equal number in each group of treatment, either with allergic (AR) and nonallergic rhinitis (NAR). At week 2, the mean PNIF score was 79.5 in the corticosteroid (CE) plus saline group and 82.0 in the saline group (p = 0.37). Also, SNOT-22 and VAS were not improved with the addition of mometasone furoate. CONCLUSIONS: Treatment with mometasone furoate nasal spray plus isotonic saline is not superior to saline alone in elderly patients with rhinitis in respect of improving nasal patency, quality of life, and reducing the intensity of symptoms. TRIAL REGISTRATION: The trial is registered at the Brazilian Clinical Trials Registry (ReBEC) #RBR-498bnq. Registered 05 July 2017.
RESUMEN
OBJECTIVES: An increasing number of complaints related to time spent in artificially ventilated buildings have been progressively reported and attributed, at least in part, to physical and chemical exposures in the office environment. The objective of this research was to investigate the association between the prevalence of work-related symptoms and the indoor air quality, comparing a sealed office building with a naturally ventilated one, considering, specially, the indoor concentration of TPM, TVOCs and the main individual VOCs. METHODS: A cross-sectional study was performed to compare the prevalence of sick building syndrome (SBS) symptoms among 1736 office workers of a sealed office building and 950 of a non-sealed one, both in Rio de Janeiro's downtown. The prevalence of symptoms was obtained by a SBS standardized questionnaire. The IAQ of the buildings was evaluated through specific methods, to determine the temperature, humidity, particulate matter and volatile organic compound (VOC) concentrations. RESULTS: Upper airways and ophthalmic symptoms, tiredness and headache were highly prevalent in both buildings. Some symptoms were more prevalent in the sealed building: "eye dryness" 33.3% and 27.1% (p: 0.01); "runny nose" 37.3% and 31.3% (p: 0.03); "dry throat" 42% and 36% (p: 0.02); and "lethargy" 58.5% and 50.5% (p: 0.03) respectively. However, relative humidity and indoor total particulate matter (TPM) concentration as well as total volatile organic compounds (TVOCs) were paradoxically greater in the non-sealed building, in which aromatic compounds had higher concentration, especially benzene. The analysis between measured exposure levels and resulting symptoms showed no association among its prevalence and TPM, TVOCs, benzene or toluene concentration in none of the buildings. CONCLUSIONS: Other disregarded factors, like undetected VOCs, mites, molds and endotoxin concentrations, may be associated to the greater prevalence of symptoms in the sealed building.

INTRODUÇAO: A asma é considerada a doença crônica mais comum na infância. Entretanto, há poucos estudos sobre sua prevalência em nosso meio. OBJETIVO: Avaliar prevalência e gravidade de sintomas de asma em escolares e adolescentes de Duque de Caxias (RJ). MÉTODO: Estudo transversal utilizando o questionário do International Study of Asthma and Allergies in Childhood. A amostra foi composta por alunos de 6, 7, 13 e 14 anos. RESULTADOS: Foram avaliados 4.040 alunos de 13 e 14 anos e 2.334 de 6 e 7 anos. A freqüência de sibilos nos últimos doze meses foi de 27,7 por cento entre os mais jovens e de 19 por cento entre os adolescentes (p < 0,0001). No primeiro grupo houve predomínio do sexo masculino (29,9 por cento vs 25,6 por cento, p = 0,01) e no segundo do feminino (21,9 por cento vs 15,8 por cento, p < 0,0001). Não existiram diferenças entre as faixas etárias relacionadas ao diagnóstico prévio de asma (cerca de 10 por cento). Sibilância aos exercícios físicos foi mais prevalente entre os adolescentes (21,4 por cento vs 7,8 por cento, p < 0,0001). A gravidade dos sintomas foi maior entre as adolescentes (asma grave: 6,6 por cento vs 4,4 por cento, p = 0,001), não havendo diferenças entre gêneros aos 6 e 7 anos. CONCLUSAO: A prevalência de asma em Duque de Caxias é alta, comparável à de outros municípios brasileiros e latino-americanos. Os valores são superiores aos 6 e 7 anos, quando os sintomas predominam no sexo masculino. Entre os adolescentes, a prevalência e a gravidade dos sintomas são maiores no gênero feminino, fato de observação recente e que parece representar novo comportamento epidemiológico da asma.

BACKGROUND: Air pollutants have been associated with the exacerbation of respiratory diseases. They may intensify the inflammatory allergic response and airways reactivity to inhaled allergens. However, it is still not clear if air pollution contributes to the increased prevalence of asthma. OBJECTIVE: To investigate if different levels of air pollution exposure can be related to differences in the prevalence of asthma. METHODS: The International Study of Asthma and Allergies in Childhood (ISAAC) protocol was used to determine and compare the prevalence of asthma among schoolchildren in 2 cities of the metropolitan region of Rio de Janeiro, Brazil, Duque de Caxias (DC) and Seropédica (SR), which have different levels of atmospheric pollution. The research involved 4,064 students aged 13 to 14 years from 49 schools in DC and 1,129 from 17 schools in SR. Air pollution was evaluated by the concentration of inhalable particulate matter (PM10). RESULTS: ISAAC's written questionnaire was answered by 4,040 students aged 13 to 14 years in DC and 1,080 in SR. Between 1998 and 2000, the PM10 annual arithmetic mean was 124 microg/m3 in DC and 35 microg/m3 in SR (acceptable level is up to 50 microg/m3). The prevalence of wheezing ever was 35.1% in DC and 29.9% in SR (P = .001), and the prevalence of wheezing in the last 12 months was 19.0% in DC and 15.0% in SR (P = .002). In DC, 14.5% of the adolescents presented 1 to 3 crises of wheezing in the last year, whereas in SR only 11.0% presented 1 to 3 crises (P = .003). CONCLUSIONS: In this study, the prevalence of asthma in adolescents was directly related to atmospheric pollution.
