RESUMEN

Since we published the "IV Brazilian Consensus on Rhinitis", in2017, several advances have been achieved and have enabled a further understanding of the different aspects of "Rhinitis". This new guideline, developed jointly by ASBAI, SBP and SBORL, represents a relevant milestone in the updated and integrated management of the different forms of the disease, and it aims to unify evidence-based approaches to improve the diagnosis and treatment of this common and often underestimated condition. The document covers a wide range of topics, including clear definitions of the different phenotypes and endotypes of rhinitis, risk factors, updated diagnostic criteria, and recommended methods for clinical and laboratory investigation. We stress the importance of detailed clinical history and objective assessment, as well as tools for control and assessing severity tools an accurate diagnostic approach to the disease. Regarding treatment, it emphasizes the treatment customization, considering the severity of symptoms, the presence of comorbidities and the impact on the patient's quality of life. We discuss different drug treatment, in addition to non-pharmacological measures, such as environmental control and specific immunotherapy; and the possible role of immunobiological agents. Furthermore, the consensus addresses issues related to patient education, prevention and management of special situations, such as rhinitis in children, in pregnant women and in the elderly. In short, the "V Brazilian Consensus on Rhinitis" represents a comprehensive and updated guide for healthcare professionals involved in the diagnosis and management of rhinitis, aiming to improve patients' quality of life through an integrated and evidence-based approach.

RESUMEN

Background: Newborn screening (NBS) for the early detection of inborn errors of immunity (IEI) has been implemented in a few countries. The objective of this study was to verify the situation and define obstacles to the implementation of NBS worldwide. Methods: A questionnaire was developed by the Inborn Errors of Immunity Committee of the World Allergy Organization (WAO) with 17 questions regarding NBS for IEI in the physician's workplace, NBS test type, problems hindering NBS implementation, reimbursement for IEI therapy, presence of a national IEI registry, referral centers, molecular diagnosis, hematopoietic stem cell transplantation centers, gene therapy, and immunoglobulin replacement therapy. The survey was sent by email once a week to doctors and others associated with WAO and the main immunology societies worldwide as a Google Form™ to be completed during September and October 2021. Results: Two hundred twenty-nine questionnaires were completed, of which 216 (94.3%) were completed by physicians. One hundred seventy-six (76.8%) physicians were both allergists and immunologists. The agreement between allergists/immunologists and non-allergists/non-immunologists for the question "Is there NBS for IEI in the country you work in?" was good (κ = 0,64: 95% CI 0.55-0.69). Ninety-eight (42.8%) participants were from Latin America, 35 (15.3%) from North America, 29 (12.6%) from Europe, 18 (7.9%) from Africa, 44 (19.2%) from Asia, and 5 (2.2%) from Oceania. More than half the participants (n = 124, 54.2%) regularly treated patients with IEI, followed by occasional treatment (n = 77, 33.6%), or never (n = 28, 12.2%). Of the respondents, 14.8% reported that their countries performed NBS for IEI, whereas 42.2% reported their countries did not. T-cell receptor excision circles was the most widely used technique in some countries, with 75 (59.9%) for the diagnosis of NBS for IEI, followed by combined use with kappa deleting-recombination excision circles. Only 13 participants (10.3%) underwent neonatal exon screening in their respective countries. Financial and technical issues were among the major obstacles to the implementation of NBS for IEI. Conclusions: This pilot study showed that few countries have implemented NBS for IEI, despite the presence of immunology referral centers and the availability of hematopoietic stem cell transplantation and intravenous immunoglobulin replacement therapy. The findings highlight the difficulties, mainly financial and technical, hindering wide application of NBS. Sharing experiences, technologies, and resources at the international level can help overcome these difficulties.

RESUMEN

Ataxia-telangiectasia (AT) is a rare genetic disorder leading to neurological defects, telangiectasias, and immunodeficiency. We aimed to study the clinical and immunological features of Latin American patients with AT and analyze factors associated with mortality. Referral centers from 9 Latin American countries participated in this retrospective cohort study, and 218 patients were included. Median (IQR) ages at symptom onset and diagnosis were 1.0 (1.0-2.0)  and 5.0 (3.0-8.0) years, respectively. Most patients presented recurrent airway infections, which was significantly associated with IgA deficiency. IgA deficiency was observed in 60.8% of patients and IgG deficiency in 28.6%. T- and B-lymphopenias were also present in most cases. Mean survival was 24.2 years, and Kaplan-Meier 20-year-survival rate was 52.6%, with higher mortality associated with female gender and low IgG levels. These findings suggest that immunologic status should be investigated in all patients with AT.

RESUMEN

PURPOSE: The prevalence of ocular allergy varies according to the population and location of the study. Severe forms of ocular allergy are associated with compromised quality of life. In this study, we aimed to evaluate the application of the Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire to children and adolescents with different subtypes of allergic conjunctivitis. METHOD: A total of 48 patients (aged 5-12 years) with allergic conjunctivitis were included in this study. They were enrolled and monitored at a specialized center. After the clinical appointment, the children responded to the questionnaire on two occasions at an interval of 30 days. Individual scores (ranging from 0 to 3) of the 16 items were added. RESULTS: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire demonstrated good translation, adaptation, and intellectual properties, with substantial internal consistency (Cronbach's α coefficient = 0.702). There was no significant difference between the responses of the two interviews, revealing good reproducibility. The moderate/severe forms of allergic conjunctivitis had significantly higher quality of life scores (indicating a poorer quality of life) than the mild forms. CONCLUSIONS: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis proved to be quick, reliable, and reproducible for assessing the quality of life in children with allergic conjunctivitis. However, its ability to detect changes resulting from symptom aggravation or treatment needs to be further evaluated.

RESUMEN

Objetivo: Identificar possíveis fatores sociodemográficos, econômicos, de saúde, ambientais e de hábitos de vida associados a efeitos adversos sobre a saúde de moradores em três cidades brasileiras. Método: Estudo transversal com abordagem quantitativa realizado nas cidades de Imperatriz (Maranhão), Palmas (Tocantins) e Salvador (Bahia). Participaram 975 pacientes (18 a 75 anos) atendidos em unidades básicas de saúde no período de junho de 2021 a junho de 2022. Esses indivíduos foram selecionados aleatoriamente (amostra de conveniência). Foi aplicado o questionário padronizado sobre fatores sociodemográficos e exposição a fatores ambientais, assim como o de hábitos de vida. Empregou-se a situação de saúde (excelente/boa x regular/ má/péssima) como desfecho, foi realizada análise multivariada seguida por regressão logística respeitando-se cada município individualmente e o seu coletivo. Os dados foram apresentados como odds ratio (OR) e intervalos de confiança de 95% (IC95%). Resultados: Em todas as cidades houve predomínio de pacientes do sexo feminino: 58,3% em Imperatriz, 67,5% em Tocantins e 65,4% em Salvador. A prevalência de tabagismo (presente e/ou passado) foi significantemente mais elevada em Salvador, assim como a de consumo de álcool. Houve maior referência de saúde regular/má/péssima entre os moradores de Imperatriz, apesar de em Salvador haver o maior relato de comorbidades. Os fatores ambientais associados à condição precária de saúde, em ambos os modelos de análise, foram: ter sido exposto durante a infância a fogão a lenha/carvão/querosene/outro; passar mais de duas horas na cozinha, com fogão em funcionamento; e residir próximo a uma fonte poluidora. Morar em Imperatriz revelou chance 1,8 vezes maior de ter saúde debilitada quando comparado aos moradores de Salvador, e de 1,7 vezes para os de Palmas. Conclusões: Profissionais de saúde deverão orientar a população quanto as questões socioambientais que interferem nos índices de saúde. Os dados demográficos, ambientais e econômicos podem interferir nas condições de saúde.

Objective: To identify potential sociodemographic, socioeconomic, health, environmental, and lifestyle factors associated with adverse health effects in residents of 3 Brazilian cities. Methods: This cross-sectional study with a quantitative approach was conducted in the cities of Imperatriz (Maranhão), Palmas (Tocantins), and Salvador (Bahia). A total of 975 patients aged 18 to 75 years treated at primary health care units from June 2021 to June 2022 were selected via convenience sampling. A standardized questionnaire on sociodemographic characteristics, exposure to environmental factors, and lifestyle habits was administered. The outcome measured was health status (excellent/good vs fair/bad/very poor). Multivariate analysis was performed using logistic regression, respecting each municipality individually and collectively. Data were presented as odds ratios (OR) and 95%CIs. Results: Women predominated in all cities: 58.3% in Imperatriz, 67.5% in Tocantins, and 65.4% in Salvador. The prevalence of smoking (present and/or past) was significantly higher in Salvador, as was the prevalence of alcohol consumption. Despite Salvador having the highest rate of comorbidities, residents of Imperatriz reported more instances of fair/poor/very poor health. Environmental factors significantly associated with poor health conditions in both analysis models included exposure to wood/ coal/kerosene/other stoves during childhood, spending more than 2 hours in the kitchen with a working stove, and living close to a pollution source. Residents of Imperatriz were 1.8 times and 1.7 times more likely to have poor health compared with residents of Salvador (a more developed center with more health resources) and Palmas, respectively. Conclusions: Health professionals should guide the population regarding socio-environmental issues affecting health indices. Demographic, environmental, and economic data can impact health conditions.

RESUMEN

O Relatório Lancet Countdown tem feito importantes contribuições ao denunciar os principais agravos à saúde ambiental, graças à ação antropogênica, cada vez mais intensa. O desflorestamento, os incêndios florestais, cada vez mais incontroláveis, a seca, o consumo de combustíveis fósseis, o uso de energia não renovável, propiciam o aparecimento de alterações climáticas caracterizadas por ondas de calor, tempestades cada vez mais intensas, inundações e o consequente comprometimento da saúde dos humanos. A versão Lancet Countdown South America apresenta de forma clara e chocante as alterações no continente e faz chamamento para que essas alterações sejam bloqueadas, pois ainda há tempo.

The Lancet Countdown Report has made significant contributions by exposing the main impacts on environmental health caused primarily by increasingly intense anthropogenic action. Deforestation, increasingly uncontrollable forest fires, drought, fossil fuels, and nonrenewable energy contribute to the onset of climate change. This change is characterized by heat waves, increasingly intense storms, and floods that, consequently, compromise human health. The South America report of The Lancet Countdown highlights the alarming changes occurring in the continent and urges action to stop these changes while there is still time.

RESUMEN

INTRODUÇÃO: A anafilaxia é uma reação alérgica multissistêmica grave, de início agudo e potencialmente fatal. Poucos são os dados sobre sua epidemiologia no Brasil. O Registro Brasileiro de Anafilaxia da Associação Brasileira de Alergia e Imunologia (RBAASBAI) teve como objetivo ampliar o conhecimento sobre anafilaxia em indivíduos brasileiros. MÉTODOS: Estudo observacional transversal com questionário online sobre dados demográficos, desencadeantes suspeitos, manifestações clínicas, atendimento durante a reação, investigação diagnóstica e aconselhamento após a reação de pacientes que experimentaram uma reação anafilática. RESULTADOS: Entre junho/2021 e abril/2023, foram incluídos 237 pacientes (131 femininos): 99 crianças/adolescentes; 127 adultos e 11 idosos. Houve predomínio de meninos entre crianças/adolescentes (55,5%), e de mulheres entre os adultos (64,5%), e mediana de idade de 22 anos (< 1 a 77 anos). As manifestações cutâneas (92,8%) foram as mais frequentes, seguidas pelas respiratórias (70,1%), gastrointestinais (52,3%), neurológicas (36,3%) e cardiovasculares (35,3%). Os principais desencadeantes foram: alimentos (43,0%), medicamentos (26,2%), himenópteros (21,6%) e látex (2,5%); os alimentos entre crianças (leite, ovo, amendoim/castanhas), e os fármacos (anti-inflamatórios e antibióticos) entre os adultos. Quanto ao tratamento, 61,1% recebeu adrenalina (52,7% por profissional e 8,4% via autoinjetor de adrenalina -AIA). Uma adolescente (12 anos) faleceu após picada de abelha. A maioria recebeu plano escrito de emergência (78,1%) e foi ensinada a usar o AIA (70%). CONCLUSÃO: Os alimentos foram os desencadeantes mais comuns entre crianças/adolescentes, e os fármacos entre adultos brasileiros. A adrenalina continua sendo subutilizada, reforçando a necessidade de maior disseminação do tratamento adequado da anafilaxia.

INTRODUCTION: Anaphylaxis is a life-threatening, acute, severe multisystem allergic reaction.There is little data on its epidemiology in Brazil. The Brazilian Anaphylaxis Registry of the Brazilian Association of Allergy and Immunology (RBA-ASBAI) was devised to expand knowledge about anaphylaxis in Brazilian individuals. METHODS: Cross-sectional observational study using an online questionnaire to collect data on demographics, suspected triggers, clinical manifestations, treatment during the reaction, diagnostic workup, and post-reaction counseling in patients who have experienced an anaphylactic reaction. RESULTS: Between June 2021 and April 2023, 237 patients were included (131 female): 99 children/adolescents (<18yo), 127 adults (18-64yo), and 11 older adults (65-77yo). There was a male predominance in the pediatric group (55.5%), while females were predominant among adults (64.5%). The median age was 22 years (range, <1 to 77). The most frequent clinical manifestations were cutaneous (92.8%), followed by respiratory (70.1%), gastrointestinal (52.3%), neurological (36.3%), and cardiovascular (35.3%). The most common triggers were foods (43.0%), drugs (26.2%), venoms (21.6%), and latex (2.5%). Foods (milk, egg, peanuts/tree nuts) predominated among children, versus drugs (mostly nonsteroidal anti-inflammatory drugs and antibiotics) among adults. Regarding treatment, 61.1% received epinephrine (52.7% by a healthcare professional and 8.4% via epinephrine auto-injector [EAI]). One teenager (12yo) died due to a bee sting. Most patients received a written emergency plan (78.1%) and were taught how to use the EAI (70%). CONCLUSION: Foods were the most common triggers of anaphylaxis among Brazilian children and adolescents, while drugs predominated among adults. Epinephrine continues to be underused, highlighting the need for greater awareness of proper treatment of anaphylaxis.

RESUMEN

OBJETIVO: A relação entre exposição ambiental e risco à saúde é amplamente reconhecida e a avaliamos em cinco países da América Latina com condições culturais distintas, mas com Índices de Desenvolvimento Humano semelhantes. MÉTODOS: Estudo transversal envolvendo 3.016 indivíduos (18 a 75 anos) oriundos de: Argentina (n = 878), Brasil (n = 1.030), México (n = 272), Paraguai (n = 508) e Peru (n = 328). A seleção foi aleatória e todos responderam questionário padronizado (fatores sociodemográficos, fatores ambientais e hábitos de vida) derivado do Clinical Screening Tool for Air Pollution Risk. Segundo o estado atual de saúde, foram categorizados em: saúde regular/má/péssima ou excelente/boa. Tendo-a como desfecho, realizou-se análise multivariada.Os dados foram apresentados como razão de verossimilhança (RV) e intervalos de confiança de 95% (IC 95%), tendo-se 5% o nível de significância. RESULTADOS: Foram significantemente associados a pior percepção de situação de saúde: morar em qualquer um dos países, ter umidade na residência (OR = 1,68; IC 95%: 1,33-2,12), dirigir automóvel com janelas abertas (OR = 1,31; IC 95%: 1,03-1,65), ter baixa renda familiar (OR = 1,59; IC 95%: 1,26-2,01), nível educacional incompleto (OR = 1,54; IC 95%: 1,22-1,94), histórico pessoal/familiar de hipertensão arterial (OR = 2,25; IC 95%: 01,64-3,09), doença pulmonar obstrutiva crônica/asma (OR = 1,74; IC 95%: 1,28-2,36), diabete melito (OR = 3,74; IC 95%: 2,23-6,29), obesidade (OR = 1,84; IC 95%: 1,84-3,19) ou comorbidades oftalmológicas (OR = 1,89; IC 95%: 1,55-2,30); realizar exercícios ao ar livre (OR = 1,60; IC 95%: 1,31-1,96). CONCLUSÕES: Apesar das diferentes exposições a que foram submetidos, alguns fatores permanecem muito significativos, e ter baixa renda familiar, expor-se à poluição e ter antecedentes de doenças crônicas foram associados à percepção de condição ruim de saúde.

OBJECTIVE: The relationship between environmental exposure and health outcomes is well known.We investigated this relationship in five Latin American countries with different cultural backgrounds but similar Human Development Indexes. METHODS: This was a cross-sectional study involving 3,016 individuals (18 to 75 years old) from Argentina (n=878), Brazil (n=1030), Mexico (n=272), Paraguay (n=508), and Peru (n=328). Participants were randomly selected and responded to a standardized questionnaire (including sociodemographic and environmental factors and lifestyle habits) derived from a clinical screening tool for air pollution risk. Based on their current health status, participants were categorized as having regular/bad/very bad or excellent/good health. Multivariate analysis was conducted, and data were presented as likelihood ratios and 95% confidence intervals (95%CI).The significance level was set at 5%. RESULTS: Living in any of the study countries; indoor humidity (OR=1.68; 95%CI: 1.33-2.12); driving with the windows open (OR=1.31; 95%CI: 1.03-1.65); low family income (OR=1.59; 95%CI: 1.26-2.01); incomplete education (OR=1.54; 95%CI: 1.22-1.94); personal/family history of hypertension (OR=2.25; 95%CI: 01.643.09), chronic obstructive pulmonary disease/asthma (OR=1.74; 95%:CI: 1.28-2.36), diabetes (OR=3.74; 95%CI:2.23-6.29), obesity (OR=1.84; 95%CI: 1.84-3.19), or ocular comorbidities (OR=1.89; 95%CI: 1.55-2.30); and exercising outdoors (OR=1.60; 95%CI: 1.31-1.96) were significantly associated with a worse perceived health status. CONCLUSIONS: Despite the different exposures to which participants were subjected, some factors remain very significant. Low family income, exposure to pollution, and a history of chronic diseases were associated with the perception of a poor health condition.

RESUMEN

ABSTRACT Purpose: To determine normal corneal tomographic parameters in children and adolescents without corneal disease or atopy diagnosis. Methods: This descriptive cross-sectional study evaluated patients aged 8-16 years who underwent a complete slit-lamp biomicroscopic examination and tomographic corneal evaluation by a dual Scheimpflug analyzer, excluding those with ocular disease (including allergic conjunctivitis) or a positive prick test for systemic atopies. Results: A total of 170 patients were evaluated, and 34 patients (68 eyes) were analyzed once the exclusion criteria were applied. The sample's mean age was 10.76 ± 2.31 years; with 19 (55.9%) men and 15 (44.1%) women. The mean keratometry in the flat meridian (Kflat), steep meridian (Ksteep), and maximum (Kmax) were 42.37 ± 1.63D, 43.53 ± 1.65D, and 43.90 ± 1.73D, respectively. The mean values for corneal asphericity (ε2) and thinnest point were 0.28 ± 0.11 and 550.20 ± 37.90 μm, respectively. The inferior-superior asymmetry ratio (I-S) and coma were 0.74 ±0.59D and 0.28 ± 0.12D, respectively. Conclusion: The knowledge of normal corneal tomographic parameters and their variation in children and adolescents without corneal disease or atopy may be useful for diagnosing keratoconus and initiating early disease treatment.

RESUMO Objetivo: Identificar parâmetros tomográficos de normalidade em córneas de crianças e adolescentes sem a presença de atopias sistêmicas e alergias oculares. Métodos: Este estudo descritivo transversal avaliou pacientes com idade entre 8 e 16 anos que foram submetidos a exame biomicroscópico completo por lâmpada de fenda e avaliação tomográfica da córnea por tomógrafo dual Scheimpflug, excluindo pacientes com doença ocular (incluindo conjuntivite alérgica) ou prick test positivo para atopias sistêmicas. Resultados: Cento e setenta pacientes foram avaliados e após cumpridos os critérios de exclusão, 34 (68 olhos) foram analisados. A média etária da amostra foi 10,76 ± 2,31 anos; 19 (55,9%) eram meninos e 15 (44,1%) meninas. A média da ceratometria em dioptrias (D) no meridiano mais plano (Kflat), mais curvo (Ksteep) e máxima (Kmax) foram 42,37 ± 1,63D, 43,53 ± 1,65D e 43,90 ± 1,73D, respectivamente. Os valores médios da asfericidade corneana (ε2) e do ponto mais fino da córnea foram 0,28 ± 0,11 e 550,20 ± 37,90 micras (μm). A assimetria corneana inferior-superior (I-S) e coma foi em média 0,74 ± 0,59D e 0,28 ± 0,12D, respectivamente. Conclusão: O conhecimento dos valores médios e sua variação de parâmetros tomográficos da córnea em crianças e adolescentes sem atopias sistêmicas ou alergias oculares pode ser útil para o diagnóstico precoce do ceratocone e o seu tratamento em estágio inicial.

RESUMEN

ABSTRACT Purpose: The prevalence of ocular allergy varies according to the population and location of the study. Severe forms of ocular allergy are associated with compromised quality of life. In this study, we aimed to evaluate the application of the Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire to children and adolescents with different subtypes of allergic conjunctivitis. Method: A total of 48 patients (aged 5-12 years) with allergic conjunctivitis were included in this study. They were enrolled and monitored at a specialized center. After the clinical appointment, the children responded to the questionnaire on two occasions at an interval of 30 days. Individual scores (ranging from 0 to 3) of the 16 items were added. Results: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis questionnaire demonstrated good translation, adaptation, and intellectual properties, with substantial internal consistency (Cronbach's α coefficient = 0.702). There was no significant difference between the responses of the two interviews, revealing good reproducibility. The moderate/severe forms of allergic conjunctivitis had significantly higher quality of life scores (indicating a poorer quality of life) than the mild forms. Conclusions: The Brazilian-Portuguese version of the Quality of Life in Children with Keratoconjunctivitis proved to be quick, reliable, and reproducible for assessing the quality of life in children with allergic conjunctivitis. However, its ability to detect changes resulting from symptom aggravation or treatment needs to be further evaluated.

RESUMEN

Exposure to radon can impact human health. This is a nonsystematic review of articles written in English, Spanish, French, or Portuguese published in the last decade (2013-2023), using databases such as PubMed, Google Scholar, EMBASE, and SciELO. Search terms selected were radon, human health, respiratory diseases, children, and adults. After analyzing the titles and abstracts, the researchers initially identified 47 studies, which were subsequently reduced to 40 after excluding reviews, dissertations, theses, and case-control studies. The studies have shown that enclosed environments such as residences and workplaces have higher levels of radon than those outdoors. Moreover, radon is one of the leading causes of lung cancer, especially in nonsmokers. An association between exposure to radon and development of other lung diseases, such as asthma and COPD, was also observed. It is crucial to increase public awareness and implement governmental control measures to reduce radon exposure. It is essential to quantify radon levels in all types of buildings and train professionals to conduct such measurements according to proven efficacy standards. Health care professionals should also be informed about this threat and receive adequate training to deal with the effects of radon on human health.

RESUMEN

OBJECTIVE: To assess the impact of microplastics (MPs) on human health. DATA SOURCE: The authors conducted a non-systematic review of articles published in English, Portuguese, French, and Spanish in the last decade in the following databases: PubMed, Google Scholar, EMBASE, and SciELO. The keywords used were: microplastics OR nanoplastics OR marine litter OR toxicology OR additives AND human health OR children OR adults. DATA SUMMARY: MPs are a group of emerging contaminants that have attracted scientific interest and societal attention in the last decade due to their ubiquitous detection in all environments. Humans can primarily be exposed to MPs and nanoplastics via oral and inhalation routes, but dermal contact cannot be overlooked, especially in young children. The possible toxic effects of plastic particles are due to their potential toxicity, often combined with that of leachable additives and adsorbed contaminants. CONCLUSIONS: Unless the plastic value chain is transformed over the next two decades, the risks to species, marine ecosystems, climate, health, economy, and communities will be unmanageable. However, along with these risks are the unique opportunities to help transition to a more sustainable world.

RESUMEN

Background: Hereditary angioedema (HAE) is an autosomal dominant disease characterized by recurrent episodes of subcutaneous or mucosal edema caused by excess bradykinin. The aim of the present study was to assess the knowledge of pediatricians about hereditary angioedema. Methods: An online survey with 12 HAE-related and 14 demographics-related questions was e-mailed to all pediatricians who were members of the Brazilian Society of Pediatrics (n = 17 145) once a week during the months of June and July 2021. The electronic questionnaire assessed clinical manifestations, diagnosis, and treatment of hereditary angioedema in children and adolescents. Results: Four hundred and fifty-five pediatricians responded to the questionnaire (2.6%), of whom 55 (12.1%) were board certified in Allergy and Immunology (A/I), while 400 (87.9%) were not (N-A/I). Three hundred and sixty-eight (80.9%) were female, 289 (55.7%) were under 50 years of age, 286 (62.9%) graduated from Medical School more than 10 years previously, 83 (18.2%) held an MSc/PhD degree, and 253 (55.6%) were living in the Southeast Region of Brazil. The median number of correct answers to the questions related to HAE among A/I was 7 out of 12 (58.3%), with median ranging from 4.5 to 8 correct answers, while for N-A/I it was 3 (25%), with median ranging from 2.5 to 4 correct answers (p < 0.001). Conclusion: Knowledge about HAE among Brazilian pediatricians, whether board certified in Allergy and Immunology or not, was unsatisfactory. HAE is a rare disease, largely unknown among physicians; therefore, increasing awareness may lead to improvement in diagnosis and treatment.

RESUMEN

Introducción. La salud ambiental infantil es la rama de la pediatría que estudia la influencia del medioambiente en la salud y la enfermedad de los niños. Las exposiciones ambientales globales representan una seria amenaza para la salud, lo que justifica una mayor investigación y acción. Objetivo. Evaluar la salud ambiental de una muestra de niños que viven en áreas urbanas y rurales de la ciudad de Uruguaiana, Brasil. Población y métodos. Se incluyeron padres/tutores (n = 714) de niños atendidos en el Policlínico Infantil de la Ciudad de Uruguaiana de enero a octubre de 2021, que respondieron la anamnesis ambiental en pediatría (Sociedad Brasileña de Pediatría). Los datos obtenidos se analizaron según la residencia en zona urbana o rural, o el ingreso familiar. Resultados. Al comparar los habitantes de la zona urbana (n = 660) con los de la zona rural (n = 54), verificamos que entre los de la zona rural fue significativamente mayor la actividad con productos químicos (15 % vs. 32,7 %; p = 0,004), vivir cerca de plantación (7,5 % vs. 74,5 %; p <0,001) o con fuente de contaminación (4,8 % vs. 32,7 %; p <0,001), tener perro (62 % vs. 87,3 %; p <0,001), usar plaguicidas (0,6 % vs. 32,7 %; p <0,001) y exposición a contaminación química (2,6 % vs. 18,2 %; p <0,001). En el área urbana predominó la exposición al tránsito de vehículos cerca de la vivienda (85 % vs. 48,1 %; p <0,001), renta media inferior a 3 salarios mínimos (90 %) y baja escolaridad. Conclusión. Realizar la anamnesis ambiental es fundamental para la detección de amenazas ambientales presentes en los lugares donde los niños y adolescentes viven, aprenden, juegan y estudian.

Introduction. Children's environmental health studies the influence of the environment on health and disease in children. Global environmental exposures pose a serious threat to health, warranting further research and action. Objective. To assess the environmental health of a sample of children living in urban and rural areas in Uruguaiana, Brazil. Population and methods. We included parents/legal guardians (n = 714) of children seen at Policlinica Infantil de Uruguaiana between January and October 2021, who completed the environmental history- taking in pediatrics (Brazilian Society of Pediatrics). Collected data were analyzed based on place of residence (urban or rural) or household income. Results. The comparison between inhabitants of the urban area (n = 660) and the rural area (n = 54) established that, among those living in the rural area, activity with chemical substances (15% versus 32.7%; p = 0.004), living near a plantation (7.5% versus 74.5%; p < 0.001) or near a source of contamination (4.8% versus 32.7%; p < 0.001), having a dog (62% versus 87.3%; p < 0.001), using pesticides (0.6% versus 32.7%; p < 0.001), and exposure to chemical contamination (2.6% versus 18.2%; p < 0.001) were significantly higher. In the urban area, exposure to vehicle traffic near the house (85% versus 48.1%; p < 0.001), an average income below 3 minimum wages (90%), and a low level of education predominated. Conclusion. Environmental history-taking is critical for the detection of environmental threats present in the areas where children and adolescents live, learn, play, and study

RESUMEN

Hereditary angioedema (HAE) is a rare disorder that causes unpredictable and debilitating cutaneous and submucosal edema and can lead to death. HAE can impair patients' ability to perform daily activities, proportional to pain severity, with patients reporting lower productivity, missed time from work or school and potentially resulting in missed career and educational opportunities. Many patients with HAE experience a significant psychological burden, including anxiety and depression. Available treatment aims to prevent and/or treat HAE attacks as they occur, to reduce morbidity and mortality and, finally, to improve health-related quality of life. Two different validated specific angioedema instruments are available to assess patients' quality of life. The Angioedema Quality of Life Questionnaire (AE-QoL) examines diagnosed patients' quality of life but is not specific for HAE. The disease-specific questionnaire is the Hereditary Angioedema Quality of Life (HAE-QoL), and the first used for hereditary angioedema with C1 inhibitors (C1-INH) deficiency. These quality-of-life instruments are helpful to the HAE patients' assessment and to the development of better therapeutic strategies as clinical tools, as defined by international guidelines. Considering this context, this review was conducted to compare the effects of acute vs. long-term prophylaxis on HAE patients' health-related quality of life. In addition, the prevalence of anxiety and depression among these individuals was also reviewed.

RESUMEN

OBJECTIVE: To determine the prevalence of allergic rhinitis and associated factors in adolescents and in their parents/guardians. METHODS: A cross-sectional study, applying a standardized and validated written questionnaire. Adolescents (13-14 years old; n=1,058) and their parents/guardians (mean age=42.1 years old; n=896) living in the city of Uruguaiana, southern Brazil, responded to the Global Asthma Network standard questionnaires. RESULTS: The prevalence of allergic rhinitis in adolescents was 28.0%, allergic rhinoconjunctivitis, 21.3%, and severe forms of allergic rhinitis, 7.8%. In the adults, the prevalence of allergic rhinitis was 31.7%. Some associated factors with allergic rhinitis in adolescents include low physical exercise (OR 2.16; 95%CI 1.15-4.05), having only one older sibling (OR 1.94; 95CI 1.01-3.72) and daily meat consumption (OR 7.43; 95% CI 1.53-36.11). In contrast, consuming sugar (OR 0.34; 95%CI 0.12-0.93) or olive oil (OR 0.33; 95%CI 0.13-0 .81) once or twice a week, and eating vegetables daily (OR 0.39; 95%CI 0.15-0.99) were considered factors negatively associated. In adults, exposure to fungi at home (OR 5.25; 95%CI 1.01-27.22) and consumption of meat once or twice a week (OR 46.45; 95CI 2.12-1020.71) were factors associated with the medical diagnosis of allergic rhinitis, while low education (OR 0.25; 95%CI 0.07-0.92) was found to be a factor negatively associated. CONCLUSIONS: The prevalence of allergic rhinitis in adolescents is high, as well as its medical diagnosis in adults living in Uruguaiana. Environmental factors, especially food habits, were associated with findings in both groups.

RESUMEN

Este trabalho tem como objetivo investigar a associação entreo o uso dos cigarros eletrônicos e doenças pulmonares em adolescentes. Foi realizada uma revisão sistemática na base de dados PubMed. Os termos Mesh incluídos na busca foram "Electronic Nicotine Delivery Systems" e "Lung Diseases" e sinônimos no título e abstract, com o filtro de idade "child: birth - 18 years", para buscar artigos relacionados ao uso de cigarros eletrônicos e doenças pulmonares em adolescentes. Os critérios de elegibilidade consistiram em: usuários adolescentes, exposição ao cigarro eletrônico e doença pulmonar como desfecho. Os artigos foram selecionados por uma revisão pareada de maneira independente, primeiramente com a leitura dos títulos e resumos, seguida da leitura integral dos artigos selecionados, os quais foram analisados pela ferramenta New Castle-Ottawa quanto sua qualidade, e receberam entre 5 e 7 estrelas. Os dados encontrados foram extraídos para a realização da metanálise. Inicialmente foram encontrados 61 artigos, sendo seis considerados elegíveis, todos transversais e com aplicação de questionários. Na metanálise foi encontrada uma associação significativa entre o uso de cigarro eletrônico e exacerbação de asma (OR ajustado 1,44; IC 95% 1,17­1,76). Não foram encontrados estudos que avaliassem a associação do cigarro eletrônico e outras doenças pulmonares, incluindo EVALI (E-cigarette or Vaping product use-Associated Lung Injury), em adolescentes. Na metanálise foi encontrada uma associação significativa entre exacerbações de asma e uso de cigarros eletrônicos em adolescentes com asma crônica e nos previamente hígidos.

This study aims to investigate the association between electronic cigarette use and lung disease in adolescents. A systematic review was conducted in PubMed. We used the MeSH terms "Electronic Nicotine Delivery Systems" and "Lung Diseases" as well as synonyms in the title and abstract, with the age filter "child: birth - 18 years" to search for articles related to electronic cigarette use and lung disease in adolescents. The eligibility criteria consisted of adolescent users and exposure to e-cigarettes that resulted in lung disease. The articles were selected by independent assessment, reading first the titles and abstracts, then the full text of the selected articles. The Newcastle-Ottawa Scale was used to assess study quality, and the included studies received between 5 and 7 stars. Finally, the data were extracted for meta-analysis. Initially, 61 articles were found and 6 were considered eligible, all of which were cross-sectional and applied questionnaires. The meta-analysis found a significant association between electronic cigarette use and asthma exacerbation (adjusted OR 1.44 95% CI 1.17 - 1.76). However, no studies evaluated the association with other lung diseases, including electronic cigarette or vaping product use-associated lung injury in adolescents. The metaanalysis revealed a significant association between e-cigarette use and asthma exacerbation among adolescents with chronic asthma, as well as among their previously healthy peers.

RESUMEN

Climate change is a huge and present threat to human health. This article aims to deepen the knowledge about the environmental impact of inhaler devices on their carbon footprint for patients and health professionals, providing information that allows a better choice of the type of device to be prescribed for the treatment of asthma and COPD. This narrative and nonsystematic review was carried out by searching databases (PubMed, Google Scholar, SciELO, and EMBASE) for articles published between 2017 and 2022, written in Portuguese or in English, using the search words "inhalation device" OR "environmental." The review showed that global warming cannot be addressed by focusing only on inhaler devices. However, the devices that we use to treat respiratory diseases such as asthma and COPD, which are diseases that are aggravated by climate change, are also causing that change. Therefore, health professionals, patient organizations, and industries should take a lead in health policies to offer affordable alternatives to inhalers containing hydrofluoroalkane.

RESUMEN

Introduction. Children's environmental health studies the influence of the environment on health and disease in children. Global environmental exposures pose a serious threat to health, warranting further research and action. Objective. To assess the environmental health of a sample of children living in urban and rural areas in Uruguaiana, Brazil. Population and methods. We included parents/legal guardians (n = 714) of children seen at Policlinica Infantil de Uruguaiana between January and October 2021, who completed the environmental historytaking in pediatrics (Brazilian Society of Pediatrics). Collected data were analyzed based on place of residence (urban or rural) or household income. Results. The comparison between inhabitants of the urban area (n = 660) and the rural area (n = 54) established that, among those living in the rural area, activity with chemical substances (15% versus 32.7%; p = 0.004), living near a plantation (7.5% versus 74.5%; p < 0.001) or near a source of contamination (4.8% versus 32.7%; p < 0.001), having a dog (62% versus 87.3%; p < 0.001), using pesticides (0.6% versus 32.7%; p < 0.001), and exposure to chemical contamination (2.6% versus 18.2%; p < 0.001) were significantly higher. In the urban area, exposure to vehicle traffic near the house (85% versus 48.1%; p < 0.001), an average income below 3 minimum wages (90%), and a low level of education predominated. Conclusion. Environmental history-taking is critical for the detection of environmental threats present in the areas where children and adolescents live, learn, play, and study.

Introducción. La salud ambiental infantil es la rama de la pediatría que estudia la influencia del medioambiente en la salud y la enfermedad de los niños. Las exposiciones ambientales globales representan una seria amenaza para la salud, lo que justifica una mayor investigación y acción. Objetivo. Evaluar la salud ambiental de una muestra de niños que viven en áreas urbanas y rurales de la ciudad de Uruguaiana, Brasil. Población y métodos. Se incluyeron padres/tutores (n = 714) de niños atendidos en el Policlínico Infantil de la Ciudad de Uruguaiana de enero a octubre de 2021, que respondieron la anamnesis ambiental en pediatría (Sociedad Brasileña de Pediatría). Los datos obtenidos se analizaron según la residencia en zona urbana o rural, o el ingreso familiar. Resultados. Al comparar los habitantes de la zona urbana (n = 660) con los de la zona rural (n = 54), verificamos que entre los de la zona rural fue significativamente mayor la actividad con productos químicos (15 % vs. 32,7 %; p = 0,004), vivir cerca de plantación (7,5 % vs. 74,5 %; p <0,001) o con fuente de contaminación (4,8 % vs. 32,7 %; p <0,001), tener perro (62 % vs. 87,3 %; p <0,001), usar plaguicidas (0,6 % vs. 32,7 %; p <0,001) y exposición a contaminación química (2,6 % vs. 18,2 %; p <0,001). En el área urbana predominó la exposición al tránsito de vehículos cerca de la vivienda (85 % vs. 48,1 %; p <0,001), renta media inferior a 3 salarios mínimos (90 %) y baja escolaridad. Conclusión. Realizar la anamnesis ambiental es fundamental para la detección de amenazas ambientales presentes en los lugares donde los niños y adolescentes viven, aprenden, juegan y estudian.
