Analysis of brazilian pediatricians’ knowledge of cow's milk protein allergy

To analyze the knowledge of Brazilian pediatricians about cow's milk protein allergy (CMPA) using a validated questionnaire. Quantitative study with a cross-sectional design in which an online questionnaire on CMPA knowledge was applied. The sample calculation indicated 1024 participants. The online form was divided into two blocks, the first comprising questions on the identification of pediatricians, and the second comprising the validated questionnaire, built from the Brazilian Consensus on Food Allergy (2018). The general evaluation of the questionnaire showed a percentage of agreement of 91% and a Content Validity Index of 0.95. The results of the applied questionnaires were presented in absolute and relative frequencies, mean, median, standard deviation, and percentiles. The level of significance was set at 5% (p

Are pediatricians familiar with hereditary angioedema?

BackgroundHereditary 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. MethodsAn 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. ResultsFour 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). ConclusionKnowledge 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.

Reference intervals for serum immunoglobulin A levels in Brazilian children aged 1 to 10 years: a population-based study

ObjectiveTo determine reference intervals (RI) for serum immunoglobulin A (IgA) levels in healthy children aged 1 to 1 0 years residing in the central region of Brazil. MethodsThis cross-sectional study was conducted on 1,743 healthy children randomly selected from kindergartens and public schools in Cuiabá, MT, Brazil. The IgA RIs were defined using the statistical methods postulated by the guidelines of the United States Clinical and Laboratory Standards Institute, the nonparametric bootstrap method, and Horn's robust method after the correction of discrepancies by Tukey's, Dixon's, and Horn's methods, respectively. The results were defined based on the values contained between the 2.5th and 97.5th percentiles and their respective 95% confidence intervals. ResultsPartition by sex was not necessary to determine the IgA RI of the studied children. Homogeneous subgroups were identified among children aged 1–<2, 2–<5, and 5–<11 years, whose IgA-specific RIs were determined. ConclusionThe serum IgA RIs were established for three groups of Brazilian children aged 1–11 years, which differed from those currently applied in Brazilian pediatric practice and from those defined by international studies. This definition will help Brazilian pediatricians formulate an accurate diagnosis and facilitate decision-making.

Brazilian pediatricians' adherence to food allergy guidelines-A cross-sectional study.

Food allergy is an emerging clinical condition in pediatrics, so recommendations on its management have been widely published. Studying pediatricians’ adherence to these clinical practice guidelines (CPG) and understanding the reasons for their non-compliance can help to promote better management of this condition. A cross-sectional study was conducted by a survey among Brazilian pediatricians, randomly selected during the 38th Brazilian Congress of Pediatrics, which took place in October, 2017. A validated questionnaire with 16 questions addressing knowledge and practice on food allergy, as well as self-reported adherence to international guidelines was applied. Of the total of 415 pediatricians from all regions of the country who were surveyed, only 69 (16.7%) had a satisfactory adherence rate (≥80%). Adequate adherence to the guidelines was associated with the variables: ‘evaluating more than 10 children with suspected cow’s milk allergy (CMA) per month'; 'having read the Brazilian consensus'; or 'being aware of any international food allergy guideline'. In 8 of the 10 questions that assessed conscious adherence, a minority of those surveyed (20.3–42.3% variation) stated that they knew that their response was in line with the guidelines. This finding was statistically significant (p<0.05) in 7 of these 8 questions. The self-reported adherence of Brazilian pediatricians to international food allergy guidelines was low. Pediatricians who evaluated a higher number of children with suspected CMA or who were aware of the recommendations, had a higher rate of adherence. The results of the survey found that lack of resource was the major reported barrier to guideline adherence but lack of awareness must be a relevant non perceived barrier. This study shows the pediatricians´ self-reported adherence to food allergy guidelines in a widely overview for the first time in Brazil. More studies are necessary to investigate adherence to guidelines by pediatricians in other countries and to develop strategies to improve adherence.

Survey on the Adherence to the 2009 NASPGHAN-ESPGHAN Gastroesophageal Reflux Guidelines by Brazilian Paediatricians.

The aim of the study was to evaluate the management of gastroesophageal reflux in children among Brazilian pediatricians and adherence to the 2009 North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN), and European Society of Gastroenterology, Hepatology, and Nutrition (ESPGHAN) Guideline in Brazil. An observational cross-sectional study was conducted, applying a standard questionnaire with 12 questions about gastroesophageal reflux (GER) and gastroesophageal reflux disease (GERD) management in infants, children, and adolescents to the pediatricians during the 37th Brazilian Pediatrics Congress in October, 2015. Adherence to the 2009 NASPGHAN-ESPGHAN Guideline was verified through analyses of interviewees' answers. Pediatricians' demographic and professional characteristics were screened. A total of 390 Brazilian pediatricians answered the questionnaire. None showed complete adherence to Guideline recommendations. GERD diagnosis by history alone was reported by 67%, irrespective of the child's age. The mean score for diagnostic adherence to the guidelines was 0.94 ± 0.86 (range 0-4). Working in public health services (P = 0.026) was the only variable retained as a significant predictor of poor adherence for GER/GERD diagnosis after multivariate logistic regression analysis. No significant statistical differences were found between Brazilian regions on total score (P = 0.774). Proton pump inhibitors were prescribed by 28.4% of the pediatricians independent of child's age, and 59% use proton pump inhibitors to treat babies with unexplained crying and/or distressed behavior. 2009 NASPGHAN-ESPGHAN Guideline recommendations had poor adherence by Brazilian pediatricians. Studies evaluating the reasons for the poor adherence to NASPGHAN/ESPGHAN guidelines are urgently needed.

The uptake of safe infant sleep practices by Brazilian pediatricians: a nationwide cross-sectional survey

ObjectiveSudden infant death syndrome (SIDS) is a major cause of death among children aged <1 year. Campaigns to educate physicians have been effective to reduce its incidence. We assessed the knowledge of Brazilian pediatricians' regarding risk factors for SIDS, their familiarity with the first Brazilian SIDS campaign launched in 2009, and self-reported changes in practices following this campaign. MethodsActive members of the Brazilian Society for Pediatrics who had been in practice for at least two years at the time of the campaign were invited. Pediatricians answered an online survey including eight multiple-choice questions and one open-ended question. Invitees were chosen by chance draw to reflect the geographic distribution of pediatricians in the five regions of the country. ResultsThe survey was answered by 1654 pediatricians (mean [SD] age: 46 [11.5] years; mean [SD] professional practice time: 20.2 [11.52] years). Bedding items (77.7%), prone sleeping position (72.9%), bed sharing (66.3%), and smoking (59.2%) were recognized as risk factors for SIDS. Most pediatricians (88.2%) were familiar with the campaign, and 84.7% were aware of the current recommendation of supine sleeping position to prevent SIDS. The effectiveness of the first Brazilian SIDS campaign could be measured by a change in practice; before the campaign, 67.5% recommended lateral position and 23.1% the supine, and after the campaign, 76.2% recommended supine and 10.4% lateral. However, 12.8% still recommend prone position. ConclusionsThe majority of pediatricians changed their advice to parents after the educational campaign and became familiar with risk factors for SIDS. Continuous educational campaigns focusing on physicians resistant to changing practices should be provided.

Knowledge and practice of Brazilian pediatricians on gastroesophageal reflux disease in infants

ObjectiveTo assess the knowledge and practice of pediatricians about infants with physiological reflux and gastroesophageal reflux disease. Methods140 pediatricians were interviewed during two scientific events in 2009 and 2010. The questions referred to two clinical cases of infants. One with symptoms of infant regurgitation (physiological reflux) and another with gastroesophageal reflux disease. ResultsAmong 140 pediatricians, 11.4% (n=16) and 62.1% (n=87) would require investigation tests, respectively for infant regurgitation (physiological reflux) and gastroesophageal reflux disease. A series of upper gastrointestinal exams would be the first requested with a higher frequency. Medication would be prescribed by 18.6% (n=6) in the case of physiological reflux and 87.1% (n=122) in the case of gastroesophageal reflux disease. Prokinetic drugs would be prescribed more frequently than gastric acid secretion inhibitors. Sleeping position would be recommended by 94.2% (n=132) and 92.9% (n=130) of the respondents, respectively for the case of physiological reflux and gastroesophageal reflux disease; however, about half of the respondents would recommend the prone position. Only 10 (7.1%) of the pediatricians would exclude the cow's milk protein from the infants' diet. ConclusionsApproaches different from the international guidelines are often considered appropriate, especially when recommending a different position other than the supine and prescription of medication. In turn, the interviews enable us to infer the right capacity of the pediatricians to distinguish physiologic reflux and gastroesophageal reflux disease correctly.

What Do Brazilian Pediatricians Know About Celiac Disease?

Celiac disease (CD) is a common illness, affecting 0.5-1% of the population. Its classic presentation consists of gastrointestinal symptoms, however, many extra-intestinal symptoms and some associated diseases have been studied. Pediatricians should know the typical and atypical presentations of CD and how to diagnosis and treat its complications. The aim of this study was describe what pediatricians in Brazil know about CD. A descriptive, cross-sectional study with pediatricians who participated in the Nestlé Pediatrics Course, in the city of Natal, Brazil, in 2008. They were asked to complete a self-applicable questionnaire covering aspects concerning the prevalence, diagnosis, and treatment of CD and the conditions associated with this disease. A total of 632 pediatricians completed the questionnaire. The majority of respondents (82.9%) were female. All the geographical regions of Brazil were represented. More than 65% of respondents had undergone specialist training in pediatrics, and 40% of respondents had worked as pediatricians for more than 25 years. Only 22% replied that celiac disease may be asymptomatic, 57% stated that antigliadin antibody measurement represents the best screening tool for the disease, and two-thirds replied that bowel biopsy would be the most indicated method. The pathologies and conditions associated with celiac disease were identified by fewer than 50% of respondents. Exclusion of gluten from the patient's diet was mentioned as the treatment for celiac disease by 86.4% of the pediatricians. We conclude that pediatricians have superficial information about CD. The need for relevant information on celiac disease is fundamental and is recognized by the pediatricians themselves.

O conhecimento de pediatras sobre alergia alimentar: estudo piloto

OBJETIVO: Avaliar o conhecimento de pediatras sobre alergia alimentar. MÉTODOS: Dados obtidos de questionário padronizado, postado e respondido por pediatras filiados à Sociedade Brasileira de Pediatria (SBP). Digitação dos dados em planilha Excel e análise de freqüência de respostas afirmativas em porcentagem. RESULTADOS: Foram analisados 895 questionários preenchidos por pediatras de todo o país, com predomínio da região Sudeste (61,6%). Segundo os pediatras entrevistados, as manifestações diagnósticas de alergia alimentar são: respiratórias, cutâneas e sistêmicas, em iguais proporções. Ainda segundo estes pediatras, leite de vaca (98,9%), clara de ovo (58,7%) e amendoim (50,9%) são os principais alimentos associados a essas manifestações. Embora 74,8% dos respondedores tivessem identificados os corantes e aditivos alimentares como responsáveis pela alergia alimentar, apenas 19,4% conheciam o código de identificação da tartrazina. CONCLUSÕES: Os dados apresentados reforçam a necessidade de ampliação dos conhecimentos dos profissionais de saúde sobre o diagnóstico e tratamento da alergia alimentar, com o objetivo de garantir o uso de critérios diagnósticos e terapêuticos mais adequados.

The Internet—current trends and future expectations among Brazilian pediatricians and otolaryngologists with a special interest in pediatric otolaryngology

Objective: To assess Internet use among a group of Brazilian pediatricians and otolaryngologists and to inquire about possible Web based medical resources. Methods: Questionnaires were distributed among attendees of a 2001 Pediatric Otolaryngology meeting in Brazil. Multiple choice or yes/no questions related to the use of the Internet among physicians were presented. Results: All of the 99 respondents of an estimated 900 attendees, had Internet access (high-speed 18%, conventional 77%); 52% at home, 42% in the office and 6% at both sites. Eighty-one percent of those responding regularly used the Internet for medical updating. Sharing a pediatric otolayngology medical association Web site with patients was desired by 73%; an interest in personal Web based medical information and updates was demonstrated by 97%. Five percent of respondents already had established personal practice Web sites and 54% agreed with potential benefits for improving medical practice. Conclusion: The potential role of electronic communication and a desire to establish a pediatric otolaryngology Web site that would maximize inclusiveness is appreciated by this group of Brazilian otolaryngologists and pediatricians.

Dengue

OBJECTIVE: To review the literature about epidemiological, clinical and preventive aspects of hemorrhagic dengue fever in children, and to provide Brazilian pediatricians with an update on dengue METHODS: We reviewed MEDLINE and classic texts.RESULTS: Dengue is an arbovirus disease, transmitted by Aedes aegypti, a mosquito that feeds indoors and is disseminated in Brazil. Its clinical presentation ranges from asymptomatic forms to acute disease with fever, myalgia, headache and rash. Evolution with hemorrhage, hemoconcentration, decreased platelets and shock is characteristic of dengue shock syndrome. Mortality rate is high, chiefly in children, if not treated earlier. There is no specific antiviral treatment, but a polyvalent vaccine is presently being evaluated.CONCLUSION: Among the prevalent acute infectious diseases in our setting, dengue is one of the most frequent, and may be highly lethal if associated with shock. Vector control is still the most effective prophylactic measure.
