RESUMEN

Objetivo: Analisar a relação entre o desmame precoce e o desenvolvimento de alergias alimentares por meio de uma revisão integrativa. Método:Revisão integrativa da literatura realizada através das bases de dados Pubmed, Mesh e Scielo.Resultados:Através da busca pelos descritores determinados, foram selecionados 25 estudos científicos que atenderam aos critérios de inclusão. Devido sua grande composição, o leite humano é responsável pela promoção do crescimento das bactérias com efeito bifidogênico, estando em quantidades superiores nos lactentes em AME. Conclusão: Apesar de alguns dos estudos não mostrarem resultados significativos em relação ao leite materno ser um fator protetor contra as alergias alimentares, nenhum deles deixoude incentivar o AM ou mostrar os seus benefícios já cientificamente comprovados.


Objective: To analyze the relationship between early weaning and the development of food allergies through an integrative review. Method: Integrative literature review performed through the Pubmed, Mesh and Scielo databases. Results: Through the search for the descriptors determined, 25 scientific studies that met the inclusion criteria were selected. Due to its large composition, human milk is responsible for promoting the growth of bacteria with bifidogenic effect, being in higher amounts in infants in EBF. Conclusion: Although some of the studies did not show significant results regarding breast milk being a protective factor against food allergies, none of them failed to encourage BF or show its scientifically proven benefits.


Objetivo: Analizar la relación entre el destete precoz y el desarrollo de alergias alimentarias a través de una revisión integradora. Metodo:Revisión integradora de la literatura realizada a través de las bases de datos Pubmed, Mesh y Scielo. Resultados: A través de la búsqueda de los descriptores determinados, se seleccionaron 25 estudios científicos que cumplieron con los criterios de inclusión. Debido a su gran composición, la leche humana es responsable de promover el crecimiento de bacterias con efecto bifidogénico, estando en mayores cantidades en bebés en LME. Conclusión:Aunque algunos de los estudios no mostraron resultados significativos con respecto a que la leche materna sea un factor protector contra las alergias alimentarias, ninguno de ellos falló en fomentar la BF o mostrar sus beneficios científicamente probados.

RESUMEN

As alergias alimentares são condições muito frequentes dentre as queixas pediátricas, sendo a alergia às proteínas do leite de vaca (APLV) o tipo mais comum na infância. Apesar de sua prevalência, há controvérsias na literatura sobre o diagnóstico e o tratamento convencional. A Homeopatia oferece uma opção valiosa para a abordagem dessas patologias, uma vez que age conforme a totalidade sintomática característica de cada caso, isto é, de forma individualizada. O presente relato é sobre uma criança, do sexo masculino, com diagnóstico prévio de APLV, apresentando crises respiratórias frequentes e uso recorrente de antibióticos, além de estar submetido a uma dieta restrita. A mãe buscou tratamento homeopático como alternativa à terapêutica vigente, uma vez que os resultados obtidos até então eram pouco satisfatórios. O caso foi conduzido segundo os preceitos da homeopatia clássica hahnemanniana, com obtenção de um medicamento único segundo o método de repertorização. Optou-se pelo tratamento com o medicamento Lycopodium clavatum, considerado o mais semelhante segundo a individualidade do paciente. A criança foi acompanhada por pouco mais de um ano, observando-se melhora clínica importante da queixa inicial, além de mais qualidade de vida à criança e à família.


Food allergies are very common conditions amongst pediatric complaints, and cow's milk protein allergy (CMPA) is the most common kind in childhood. Despite its prevalence, there are controversies in the literature about diagnosis and conventional treatments. Homeopathy offers a valuable option for approaching these pathologies, since it acts according to the characteristic symptomatic totality of each case, that is, in an individualized way. This report is about a child, male, with a previous diagnosis of CMPA, with frequent respiratory crises and recurrent use of antibiotics, in addition to being submitted to a restricted diet. His mother looked for homeopathic treatment as an alternative to current therapy, since the results obtained so far were unsatisfactory. The case was conducted according to the precepts of classical Hahnemannian homeopathy, obtaining a single medicine according to the repertorization method. We opted for treatment with Lycopodium clavatum, considered the most similar according to the individuality of the patient. The child was followed up for a little over a year, and significant clinical improvement of the initial complaint was observed, in addition to better quality of life for the child and family.

RESUMEN

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.

RESUMEN

En las últimas décadas, la introducción temprana de alimentos en la dieta de los lactantes se ha descrito como un factor de riesgo para el desarrollo de ciertas patologías, entre las que destacan las alergias alimentarias. Debido a la creciente prevalencia de las alergias alimentarias, tanto en países en vías de desarrollo como en países desarrollados, resulta necesario identificar el momento óptimo de introducción de alimentos para la prevención de alergias en lactantes de alto riesgo. La evidencia más reciente, ha demostrado que las estrategias propuestas hasta el momento de retrasar la exposición a los alimentos alergénicos, no ha reducido el riesgo de desarrollar alergias. Esto ha producido un cambio de paradigma que ha derivado en la publicación de nuevas guías que recomiendan no retrasar la introducción de alimentos sólidos después de los 4-6 meses de edad, tanto en lactantes de bajo como de alto riesgo, para prevenir la alergia alimentaria. En la presente revisión, se describe la evidencia científica actual sobre la relación entre el momento de la introducción de alimentos alergénicos (maní, huevos, leche, cereales y pescado) en la dieta de los lactantes y el desarrollo de alergias alimentarias(AU)


In recent decades, the early introduction of foods in infants' diet has been described as a risk factor for developing specific pathologies, among which food allergies stand out. Due to the increasing prevalence of food allergies, both in developing and developed countries, it is necessary to identify the optimal time to introduce foods to prevent allergies in high-risk infants. The most recent evidence has shown that the strategies proposed to delay exposure to allergenic foods have not reduced the risk of developing allergies. Therefore, a paradigm shift has led to the publication of new guidelines that recommend not delaying the introduction of solid foods after 4-6 months of age, both in low-risk and high-risk infants, to prevent food allergy. In this review, we describe the current scientific evidence on the relationship between the timing of the introduction of allergenic foods (peanuts, eggs, milk, cereals, and fish) into infants' diet and the development of food allergies(AU)

RESUMEN

INTRODUCTION: Allergic diseases have become an increasingly common reality in the last years, extending beyond the family context. OBJECTIVE: Assessing the level of knowledge on asthma, food allergies and anaphylaxis of asthmatic children's parents/caregivers (PC), elementary school teachers (EST) and university students (US) in Uruguaiana, RS, Brazil. METHOD: 577 individuals (PC - N=111; EST - N=177; US - N=299) took part in the study, answering the Newcastle Asthma Knowledge Questionnaire (validated for Portuguese) and another questionnaire on Food Allergy (FA) and anaphylaxis. RESULTS: Although PC have asthmatic children, their asthma knowledge level was average, slightly above that of EST and EU. The lack of knowledge on passive smoking, use of medications and their side effects should be highlighted. US have shown to be better informed about FA and anaphylaxis. However, even though a significant proportion of respondents know the most common symptoms of FA and anaphylaxis, few named subcutaneous adrenaline as the drug of choice for treating anaphylaxis. Although a significant number of respondents know about the possibility of anaphylactic reactions happening at school or in activities outside the school, we were surprised by the absence of conditions in schools to provide emergency care to such students. CONCLUSION: Despite the high prevalence of allergic diseases in childhood, asthmatic children's parents/caregivers, elementary school teachers and university students have inadequate levels of knowledge to monitor these patients.

RESUMEN

BACKGROUND: Neuroendocrine tumors (NETs) are heterogeneous neoplasms that originate from cells with a secretory function. Small bowel NETs (SB-NETs) are related to serotonin hypersecretion which causes: flushing, diarrhea, abdominal pain, bronchoconstriction and heart involvement, also known as carcinoid syndrome (CS). CS can be confused with an allergic reaction and thus should be considered as a differential diagnosis in the allergy consult. We present the case of a pediatric patient initially referred under the suspicion of food allergies. CASE PRESENTATION: We present the case of a 17-year-old male with evanescent non-pruriginous erythematous lesions- flushing that appeared with food consumption, associated with conjunctival injection, warmth and diaphoresis after the lesions disappeared. He denied abdominal pain, diarrhea, cough or wheezing. The 24-h urinary 5-hydroxyindoleacetic acid (5-HIAA) excretion was elevated. The CT scan showed thickening of the distal ileum and multiple lesions on both hepatic lobules and the colonoscopy revealed a tumor in the ileocecal valve. Hepatic and intestinal biopsies reported a well-differentiated NET of the ileocecal valve with hepatic metastasis. He was started on octreotide and underwent a wide hepatectomy and right hemicolectomy with improvement of symptoms. CONCLUSIONS: NETs can present as carcinoid syndrome (flushing, diarrhea, abdominal pain, wheezing), which constitutes vague symptomatology and represents a challenging diagnosis for physicians. They can be confused with an allergic reaction and the allergist should consider it as a differential diagnosis. Accurate diagnostic tests will help to diagnose NETs earlier and potentially prevent carcinoid heart disease, bowel obstruction, and improve quality of life and mortality in these patients.

RESUMEN

El término alergia alimentaria se refiere a los eventos adversos a alimentos originados por mecanismo inmunológico. La alergia alimentaria puede aparecer en cualquier etapa de la vida. Es un padecimiento que, en general, se manifiesta en el lactante por llanto excesivo, cólicos, vómitos, diarreas, acompañadas de sangre y eccema en la piel. El objetivo de la investigación es demostrar la sensibilización del lactante a los alérgenos alimentarios que recibió en el útero de la madre y a través de la lactancia materna exclusiva. La metodología fue reporte de un caso al que se le suspendió la lactancia materna exclusiva y se introdujo leche en polvo hipoalergénica Puramino. La IgE total fue de 1.136 kU/l y los valores de IgE alérgeno específico para leche, el huevo y el maní mayores de 100 kU/l y para el trigo 24,4 kU/l. Se concluye así que la leche de vaca, el huevo, el maní y el trigo pueden sensibilizar al niño durante el embarazo y a través del seno materno. El uso de una dieta hipoalergénica durante el período de lactante puede revertir el proceso.(AU)


The term food allergy refers to adverse events caused by immunologic mechanism. Food allergy may appear at any stage of life, it is a condition that generally manifests itself in the baby's excessive crying, colic, vomiting, diarrhea accompanied by blood and skin eczema. The objective of the research is to demonstrate awareness infant to food allergens received in the mother's womb and through the exclusive breastfeeding. The methodology was a case report that was suspended exclusive breastfeeding and milk powder was introduced into hypoallergenic Puramino. The total IgE was 1.136 kU/L and allergen specific IgE values for milk, egg and peanut higher than 100 kU/L and wheat: 24. 4 kU/L. It is concluded that cow's milk, egg, peanuts and wheat can sensitize the child during pregnancy and through the womb. The use of a hypoallergenic diet during the infant can reverse the process.(AU)

RESUMEN

Introducción: La Gastroenteritis eosinofilica, se refiere a la eosinofilia en cualquiera de las capas de la pared del tracto gastrointestinal, es una patología rara, con incidencia no reportada y de patogenia desconocida, asociada a antecedentes de atopias y alergias alimentarias. Se requiere para su diagnóstico la evidencia histológica de eosinofilia, la ausencia de ésta en órganos extraintestinales y sin presencia de infección parasitaria. Caso clínico: Se reporta el caso de una paciente femenina de 39 años de edad, con clínica de 4 meses que inició posterior a intoxicación alimentaria y caracterizada por dolor abdominal difuso con predominio de epigástrico, opresivo, de fuerte intensidad, que mejoraba con uso de antiespasmódicos y se intensificaba con la ingestión de alimentos, acompañado de náuseas y vómitos. Se planteó el diagnóstico por imágenes de litiasis vesicular, siendo sometida a colecistectomía laparoscópica. Por persistencia de la sintomatología se realizó endoscopia digestiva superior con hallazgos sugestivos de: gastroduodenitis parasitaria y la biopsia reportó: gastroduodenitis crónica severa eosinofilica. Se indicó tratamiento a base de prednisona, obteniendo resolución completa del cuadro clínico.


Background: eosinophilic gastroenteritis, refers to eosino- philia in any of the layers of the wall of the gastrointestinal tract, it is a rare condition, with no reported incidence and unknown pathogenesis associated with a history of atopy and food allergies. It required for diagnosis histologic evidence of eosinophilia, its absence in intestinal organs without presence of parasitic infection. Case report: The case of a female patient of 39 years old, with clinical started 4 months after food poisoning, characterized by a predominance of diffuse abdominal pain epigastric, oppressive, strong intensity, which improved with use is reported antispasmodics and intensified with food intake, with nausea and vomiting. The imaging of gallstones was raised, undergoing laparoscopic cholecystec- tomy. Persistence of symptoms upper endoscopy is performed with suggestive findings: parasitic gastroduodenitis and biop- sy reported: severe chronic eosinophilic gastroduodenitis. Treatment with prednisone was indicated, obtaining complete resolution of symptoms.

RESUMEN

The most common presentation of cow's milk protein allergy (CMP) in infants is known as eosinophilic colitis (EC). The aim of this study is to evaluate EC characteristics in infants evaluated with colonoscopy due to the presence of rectorrhagia. Patients and Methods: A retrospective case-control study. Left-sided colonoscopy records of infants with persistent rectal bleeding, conducted between January 2006 and March 2011, were reviewed. The cases corresponded to infants with rectal biopsy compatible with EC and controls with negative biopsy. Telephone questionnaires to parents were conducted, evaluating personal and family history. Results: Complete records were obtained in 61 (79%) of the 77 procedures. 33 (54%) of them were males. Examination average age was 6.3 ± 5.9 months. 25 (41%) patients had EC on their histology. Between cases and controls, no significant difference in gestational age, birth weight and gender, only regarding age at the time of rectal bleeding, were observed. There was also no difference in personal history regarding obstructive bronchitis, allergic rhinitis, family history of asthma, allergic rhinitis or other food allergies. Those who received artificial feeding did not presented greater risk of EC. The most common symptoms in the cases did not differ significantly from the controls. Conclusions: The prevalence of EC in the children studied was 40.9%. Our results show that there are groups of patients with persistent rectal bleeding in which there is no personal or family history that helps diagnosing EC. An endoscopic study could be considered in these patients to establish a correct diagnosis of this condition, avoid unnecessary diets and not to delay the detection of other diseases.


En lactantes, la forma de presentación más común de la alergia a la proteína de la leche de vaca (PLV) es la colitis eosinofílica (CE). El objetivo de este trabajo es evaluar características clínicas asociadas a CE en lactantes evaluados con colonoscopía por la presencia de rectorragia. Pacientes y Método: Estudio caso-control, retrospectivo. Se revisaron registros de colonoscopía izquierda de lactantes con rectorragia persistente, realizadas entre Enero 2006 y Marzo 2011. Casos fueron lactantes con rectorragia y biopsia compatible con CE y controles aquellos con biopsia negativa. Se realizó un cuestionario vía telefónica a los padres, evaluándose antecedentes personales y familiares. Resultados: En 61 (79%) de 77 procedimientos se obtuvo registros completos. 33 (54%) eran hombres. Edad promedio del examen fue 6,3 ± 5,9 meses. 25 (41%) pacientes presentaron CE en la histología. Sin diferencia significativa en edad gestacional, peso de nacimiento ni sexo, pero si en edad de presentación de la rectorragia, entre casos y controles. Tampoco hubo diferencia en antecedentes personales de bronquitis obstructivas, rinitis alérgica, ni antecedentes familiares de asma, rinitis alérgica u otras alergias alimentarias. Quienes recibieron lactancia artificial no tuvieron mayor riesgo de CE. Los síntomas más frecuentes en los casos no se diferenciaron significativamente de los controles. Conclusión: La prevalencia de CE en los niños estudiados fue de 40,9%. Nuestros resultados muestran que hay grupos de pacientes con rectorragia persistente en los cuales no existen antecedentes de la historia familiar ni personal que permitan establecer el diagnóstico de CE. Es en estos pacientes en los cuales podría considerarse el estudio endoscópico para establecer un correcto diagnóstico de esta patología, evitar dietas innecesarias y no retrasar la detección de otras enfermedades.

RESUMEN

Las enfermedades alérgicas y el trastorno por déficit de atención son entidades frecuentes enla niñez. Alguno autores han sugerido una asociación entre estas.Objetivos: Establecer la prevalencia de alergias en niños con déficit de atención y sus características clínicasy socio-demográficas en la consulta de neurología hecha por los autores.Materiales y Métodos: Estudio descriptivo, prospectivo, de corte transversal, con muestreo no aleatorio yselección de los casos de forma consecutiva. Se entrevistaron 113 niños que cumplían los criterios de inclusión,entre junio y diciembre de 2012. La información fue consignada en un formulario que contenía variables sociodemográficasy clínicas relacionadas con el déficit de atención y con los diferentes tipos de alergias.Resultados: Entre los pacientes entrevistados, la enfermedad alérgica mas frecuente fue la rinitis alérgica conel 37.2%, seguida por el asma, con 31.9%. Sin embargo, solo el asma presentó mayor prevalencia en pacientescon trastorno de déficit de atención e hiperactividad que en la población general. La dermatitis atópica se presentóen 8.8% y alergia alimentaria en 2.7%. En el análisis exploratorio, los niños con dermatitis atópica fueronlos únicos que presentaron una asociación significativa con insomnio (OR 4.23; IC 95%, 1.06-16; p=0.02).Conclusiones: La prevalencia de asma fue mayor en los pacientes estudiados con trastorno de déficit deatención e hiperactividad que la reportada en estudios poblacionales.

RESUMEN

La incidencia de alergias alimentarias en los países desarrollados se estima que puede ser de un 3-4% en adultos y de un 6-8% en niños y sigue aumentando rápidamente. Los alérgenos alimentarios son principalmente proteínas que causan una respuesta inmune mediada por IgE, pero el mecanismo de esta respuesta todavía no es claro. La alergia al huevo es una causa frecuente de hipersensibilidad durante la niñez. La resistencia a la digestión es un criterio usado en los ensayos de alergenicidad de una proteína. En adición, es necesario tener en cuenta el efecto sobre las proteínas de los tratamientos comúnmente aplicados a los alimentos. Estos tratamientos pueden modificar la estructura de la proteína, cambiando su digestibilidad y alterando su alergenicidad.


The incidence of food allergy in developed countries is estimated to be 3-4% in adults and up to 6-8% in children, and it seems to be rising rapidly. Food allergens are mainly proteins that cause an IgE-mediated immune response, but the mechanism for this response still remains unclear. Egg allergy is a common cause of hypersensitivity in children. The resistance to digestion is one of the criteria used to assess the allergenicity of a protein. In addition, it is necessary to take into account the effect on proteins of the treatments that are commonly applied to foods. These treatments can modify the protein structure, changing the digestibility of the protein and thus altering its allergenicity.

Além disso, é preciso ter em conta o efeito sobre as proteínas dos tratamentos normalmente aplicados aos alimentos. Estes tratamentos podem modificar a estrutura da proteína, alterando a sua digestibilidade e modificando a sua alergenicidade.

RESUMEN

El dolor abdominal constituye un motivo frecuente de consulta de niños y adolescentes. Éste puede ser de origen orgánico o funcional. En menores las causas son predominantemente orgánicas, y en los mayores de 5 años sólo el de 33 por ciento tiene este origen, y el 67 por ciento es funcional. Mediante una anamnesis acuciosa y un examen físico completo, el clínico podrá hacer una aproximación diagnóstica y orientar la solicitud de exámenes de manera dirigida. El objetivo de este artículo es entregar las herramientas semiológicas para lograr este objetivo.


Abdominal pain is a frequent complain of children and adolescents. This may have an organic or functional origin. In preschool children the causes are predominantly organic, and in those older than 5 years only percent have this origin, and 67 per cent are functional. Through a diligent history and physical examination, the clinician may make a proper approach to diagnosis and ask for complementary tests, if neccesary, in a target manner The aim of this article is to provide the semiologic tools to achieve this goal.

RESUMEN

Esta comunicação apresenta o cenário da doença celíaca e suas implicações em hábitos, práticas alimentares e qualidade de vida de indivíduos intolerantes ao glúten. Apresenta dados importantes sobre a questão que, mundialmente, é considerada problema de saúde pública. Por ser uma doença cujo tratamento é fundamentalmente dietético, a terapia durante a transição alimentar deve ser bem conduzida pelo nutricionista para melhor adesão do paciente à dieta, considerando que a inclusão de novas práticas alimentares pode significar uma ruptura com a identidade individual e cultural: a alimentação de cada cidadão não pode ser deslocada da sociedade. Nesse contexto, a melhoria da qualidade de vida passa a ser um dos resultados esperados tanto das práticas assistenciais quanto das políticas públicas para o setor nos campos da promoção da saúde e da prevenção de doenças. A vigilância sanitária contempla as ações capazes de eliminar, diminuir ou prevenir riscos à saúde e de intervir nos problemas sanitários decorrentes do meio ambiente, da produção e circulação de bens e da prestação de serviços de interesse da saúde. O conhecimento do cenário da doença celíaca no País se justifica pela necessidade de fundamentar as ações da política de alimentação e nutrição ancoradas no conceito de alimentação saudável com ênfase na dieta isenta de glúten. Os artigos pesquisados foram selecionados nas bases de dados MedLine e SciELO, considerando o período de 1995 a 2006.


This study presents information on celiac disease and its implications on the eating habits and practices, as well as on the quality of life, of gluten-intolerant patients. Papers published from 1995 to 2006 were searched in the MedLine and SciELO databases. This paper includes important data about this disease, which is considered a public health problem throughout the world. Since it is a disease whose treatment is essentially dietary, therapy during food transition must be well conducted by the dietician in order to improve the patient's adherence to the diet since the introduction of new food practices may mean a rupture with the individual's culture and identity: the diet of each citizen cannot be disconnected from the society in which he or she lives in. In this context, quality of life is included, as quality of life is expected to improve both because of the care provided and because of the public policies for the sector in the areas of health promotion and prevention of diseases. Sanitary surveillance contemplates the activities that are capable of eliminating, reducing or preventing health risks and intervene in the sanitation problems that are secondary to the environment, production and circulation of goods and provision of health-related services. Knowledge about celiac disease in the country is justified because of the need to base food and nutrition policies on the concept of healthy eating, emphasizing a gluten-free diet.
