ABSTRACT
El consumo de probióticos, prebióticos y posbióticos, o su combinación, puede contribuir a mantener una microbiota intestinal saludable ya que permite la regulación de su disbiosis en el caso de algunas enfermedades o trastornos, principalmente en los trastornos gastrointestinales funcionales (TGIF). El microbioma intestinal es protagonista esencial en la fisiopatología de los TGIF a través de sus funciones metabólicas y nutricionales, el mantenimiento de la integridad de la mucosa intestinal y la regulación de la respuesta inmunitaria. Las investigaciones realizadas hasta la fecha indican que los probióticos, prebióticos y posbióticos pueden tener efectos inmunomoduladores directos y clínicamente relevantes. Existen pruebas del uso de esta familia de bióticos en individuos sanos para mejorar la salud general y aliviar los síntomas en una serie de enfermedades como los cólicos infantiles. La colonización y establecimiento de la microbiota comienza en el momento del nacimiento; los primeros 2-3 años de vida son fundamentales para el desarrollo de una comunidad microbiana abundante y diversa. Diversos estudios científicos realizados mediante técnicas tradicionales dependientes de cultivo y más recientemente por técnicas moleculares han observado diferencias en las poblaciones bacterianas de bebés sanos y aquellos que sufren TGIF, estos últimos caracterizados por un aumento de especies patógenas y una menor población de bifidobacterias y lactobacilos, en comparación con los primeros. En tal contexto, se considera que la microbiota intestinal como protagonista en el desarrollo de esos trastornos, entre ellos los cólicos infantiles, a través de sus funciones metabólicas, nutricionales, de mantenimiento de la integridad de la mucosa intestinal y regulación de la respuesta inmunitaria. Esto ha abierto la puerta al estudio de la utilización de prebióticos, probióticos y posbióticos en el tratamiento y/o prevención de los TGIF infantiles. El parto vaginal y de término así como la lactancia son fundamentales en la constitución de una microbiota saludable. Como herramientas de apoyo, existen estudios de eficacia que sustentan la administración de esta familia de bióticos, principalmente en los casos en que la lactancia no sea posible o esté limitada.

The consumption of probiotics, prebiotics, and postbiotics, or a combination of them, can contribute to maintaining a healthy intestinal microbiota as it allows the regulation of its dysbiosis in the case of some diseases or disorders, mainly in functional gastrointestinal disorders (FGIDs). The gut microbiome is an essential player in the pathophysiology of FGIDs through its metabolic and nutritional functions, the maintenance of intestinal mucosal integrity, and the regulation of the immune response. Research results thus far indicate that probiotics, prebiotics, and postbiotics may have direct and clinically relevant immunomodulatory effects. There is evidence regarding the prescription of this family of biotics in healthy individuals to improve overall health and alleviate symptoms in many conditions like infantile colic. The colonization and microbiota establishment begins at birth; the first 2-3 years of life are critical for developing an abundant and diverse microbial community. Several scientific studies performed by traditional culture-dependent techniques and more recently by molecular techniques have observed differences in the bacterial populations of healthy infants and those suffering from FGIDs, the latter characterized by an increase in pathogenic species and a lower population of bifidobacteria and lactobacilli, compared to the former. In this context, the intestinal microbiota plays a leading role in the onset of these disorders, including infantile colic, through its metabolic and nutritional functions, maintenance of the integrity of the intestinal mucosa, and regulation of the immune response. That has opened the door to the study of prebiotics, probiotics, and postbiotics usage in the treatment and or prevention of infantile FGIDs. Vaginal and term delivery and breastfeeding are fundamental in the constitution of a healthy microbiota. As supportive tools, there are efficacy studies that support the administration of this family of biotics, mainly in cases where lactation is not possible or is limited.

Resumen: SARS-CoV-2 es un virus de alta estabilidad ambiental. Es principalmente un patógeno respiratorio que también afecta el tracto gastrointestinal. El receptor ACE2 es el principal receptor de SARS- CoV-2, hay evidencia de su elevada presencia en intestino, colon y colangiocitos; igualmente se en cuentra expresado en hepatocitos pero en menor proporción. SARS-CoV-2 tiene un tropismo gas trointestinal que explica los síntomas digestivos y la diseminación viral en deposiciones. Las caracte rísticas de SARS-CoV-2 incluyen a la proteína S (Spike o Espícula) que se une de forma muy estable al receptor ACE2. La infección por SARS-CoV-2 produce disbiosis y alteraciones en el eje pulmón- intestino. A nivel intestinal y hepático produce una respuesta Linfocitos T evidente y una respuesta de citocinas que producirían daño intestinal inflamatorio. Las manifestaciones a nivel intestinal en orden de frecuencia son pérdida de apetito, diarrea, náuseas, vómitos y dolor abdominal. Éste último podría ser un marcador de gravedad. En niños la diarrea es habitualmente leve y autolimitada. A nivel hepático la hipertransaminasemia ocurre en 40-60% de los pacientes graves. SARS-CoV-2 puede per manecer en deposiciones un tiempo más prolongado que en secreciones respiratorias, este hallazgo influiría en la diseminación de enfermedad. En esta revisión se destaca la importancia de efectuar un reconocimiento precoz de las manifestaciones gastrointestinales y hepáticas, aumentar el índice de sospecha, efectuar un diagnóstico oportuno y reconocer eventuales complicaciones de la enferme dad. La potencial transmisión fecal oral puede influir en la diseminación de enfermedad. Reconocer este hallazgo es importante para definir aislamiento.
Abstract: SARS-CoV-2 is a high environmental stable virus. It is predominantly a respiratory pathogen that also affects the gastrointestinal tract. The ACE 2 receptor is the main receptor of SARS-CoV-2, with evidence of its high presence in the intestine, colon and cholangiocytes, and, in smaller proportion, in hepatocytes. SARS-CoV-2 has a gastrointestinal tropism that explains digestive symptoms and viral spread in stools. The characteristics of this virus include the S (Spike) protein that binds very stably to the ACE-2 receptor and, at the same time, SARS-CoV-2 produces dysbiosis and alterations in the gut-lung axis. It produces a clear T-cell response and a cytokines storm in the intestine and liver that would produce inflammatory bowel damage. Intestinal manifestations by order of frequency are loss of appetite, diarrhea, nausea and vomiting, and abdominal pain, where the latter could be a severity marker. In children, diarrhea is the most frequent symptom, usually mild and self-limiting. In the liver, hypertransaminasemia occurs in severe patients ranging from 40 to 60%. SARS-CoV-2 can re main in stools longer than in respiratory secretions, which would influence the spread of disease. This article highlights the importance of an early diagnosis of gastrointestinal and hepatic manifestations, increase the index of suspicion, make a timely diagnosis, and recognize eventual complications of the disease. The potential oral-fecal route of transmission may influence the disease spread. Recognizing this finding is important to define isolation.

Autism spectrum disorders (ASDs) are characterized by deficits in the individual’s ability to socialize, communicate, and use the imagination, in addition to stereotyped behaviors. These disorders have a heterogenous phenotype, both in relation to symptoms and regarding severity. Organic problems related to the gastrointestinal tract are often associated with ASD, including dysbiosis, inflammatory bowel disease, exocrine pancreatic insufficiency, celiac disease, indigestion, malabsorption, food intolerance, and food allergies, leading to vitamin deficiencies and malnutrition. In an attempt to explain the pathophysiology involved in autism, a theory founded on opioid excess has been the focus of various investigations, since it partially explains the symptomatology of the disorder. Another hypothesis has been put forward whereby the probable triggers of ASDs would be related to the presence of bacteria in the bowel, oxidative stress, and intestinal permeability. The present update reviews these hypotheses.

ABSTRACT Objective: To analyze the development and prevalence of gastrointestinal signs and symptoms associated with the development of the digestive tract, and to assess the measures aimed to reduce their negative impacts. Source of data: Considering the scope and comprehensiveness of the subject, a systematic review of the literature was not carried out. The Medline database was used to identify references that would allow the analysis of the study topics. Synthesis of results: Infants frequently show several gastrointestinal signs and symptoms. These clinical manifestations can be part of gastrointestinal functional disorders such as infantile colic, infant regurgitation, and functional constipation. Allergy to cow's milk protein and gastroesophageal reflux disease are also causes of these clinical manifestations and represent an important and difficult differential diagnosis. The diseases that course with gastrointestinal signs and symptoms can have an impact on family dynamics and maternal emotional status, and may be associated with future problems in the child's life. Comprehensive pediatric care is essential for diagnosis and treatment. Maternal breastfeeding should always be maintained. Some special formulas can contribute to the control of clinical manifestations depending on the established diagnosis. Conclusion: During the normal development of the digestive tract, several gastrointestinal signs and symptoms may occur, usually resulting from functional gastrointestinal disorders, gastroesophageal reflux disease, and allergy to cow's milk protein. Breastfeeding should always be maintained.
RESUMO Objetivo: Analisar o desenvolvimento e a prevalência de sinais e sintomas gastrintestinais associados com o desenvolvimento do tubo digestivo e as medidas que visam a diminuir suas repercussões negativas. Fontes dos dados: Considerando a abrangência e amplitude do tema, não foi feita revisão sistemática da literatura. Usou-se a base de dados do Medline para a identificação de referências bibliográficas que permitissem contemplar os temas de estudo. Síntese dos resultados: O lactente apresenta com elevada frequência sinais e sintomas gastrintestinais. Essas manifestações clínicas podem fazer parte de distúrbios funcionais gastrintestinais, como cólica, regurgitação e constipação intestinal funcional. A alergia à proteína do leite de vaca e a doença do refluxo gastroesofágico também são causas dessas manifestações clínicas e representam um importante e difícil diagnóstico diferencial. As doenças que cursam com sintomas e sinais gastrintestinais podem ter consequências na dinâmica familiar e no estado emocional das mães. Podem se associar com problemas na vida futura da criança. A atenção pediátrica completa é fundamental para o diagnóstico e o tratamento. O aleitamento natural deve sempre ser mantido. Algumas fórmulas especiais podem contribuir para o controle das manifestações clínicas na dependência do diagnóstico estabelecido. Conclusão: Durante o desenvolvimento normal do tubo digestivo podem ocorrer sinais e sintomas gastrintestinais em geral decorrentes dos distúrbios gastrintestinais funcionais, da doença do refluxo gastroesofágico e da alergia à proteína do leite de vaca. Aleitamento natural deve sempre ser mantido.

El empacho, el mal de ojo, los aires, el susto o espanto, son las principales y más reconocidas enfermedades populares latinoamericanas. Sobre el empacho la información médica, histórica y etnográfica es extensa y profunda, pues existen documentos que la registran desde el siglo XVI hasta tiempos recientes (2014), y para el caso chileno lo encontramos desde 1674. Para esta revisión fueron consultadas 109 fuentes documentales procedentes de las principales bibliotecas del país e incluso foráneas. Se encontró que la enfermedad es conocida en todo el territorio. Se trata de un trastorno de vías digestivas ocasionado por excesos alimentarios y la ingesta de productos poco o nada digeribles que provocan alteraciones del tránsito gastrointestinal. Los datos clínicos sobresalientes son gastralgia, diarrea o estreñimiento, vómitos, fiebre y otros malestares. La enfermedad es tratada a nivel doméstico, y en caso necesario se emplean especialistas populares, con excepcional visita al médico académico. Los tratamientos son múltiples, complejos y combinados; abarcan desde productos herbolarios hasta elementos rituales, sin faltar la denominada «quebradura del empacho¼. Esta somera revisión del empacho en Chile permitirá al médico pediatra adentrarse al mundo de los saberes y prácticas populares con la finalidad de mejorar su atención a los pacientes infantes y sus acompañantes familiares, pero también inducir al estudio serio y sistemático sobre esta entidad nosológica que seguirá existiendo a través del tiempo.
«Empacho¼ (abdominal pain and bloating), «mal de ojo¼ (evil eye), «los aires¼ (illnesses said to be caught by catching draughts), «el susto¼ or «espanto¼ (fright or panic), are the principal and most well-known popular Latin American illnesses. As regards empacho, the medical, historical and ethnographic information is extensive and detailed, since there documents recording it from the 16th century until recent times (2014), and in the case of Chile since 1674. For this review, 109 source documents from libraries in Chile, including some foreign ones, were consulted. It was found that the illness is known all over the country. It is a digestive system disorder caused by over-eating and the ingestion of products difficult to digest or indigestible, which cause problems in gastrointestinal transit. The most significant clinical data are gastralgia, diarrhoea or constipation, vomiting, fever, and other discomforts. The illness is treated at home, and if necessary, popular specialists are employed, with a visit to a qualified doctor being exceptional. There are many complex and combined treatments, which go from herbal products to ritual elements, not forgetting the so-called «quebradura del empacho¼. This review summary of empacho in Chile should enable the paediatrician to enter the world of popular knowledge and practices with the aim of improving the care of child patients and their families. It should also lead to the serious and systematic study of this nosological condition that will continue to exist in the future.

Etmologicamente, a palavra dispepsia (do grego dis = difícil e pepse = digestão) significa digestão difícil. Sob o ponto de vista clínico, corresponde a uma série de sintomas de origem gastroduodenal, como dor, queimação ou desconforto epigástrico, plenitude pós-prandial ou saciedade precoce associadas ou não a náusea, vômitos e distensão em andar superior do abdome. Traduz, pois, um distúrbio funcional ou orgânico, de localização epigástrica e origem gastroduodenal...
Etymologically, the greek word dis means hard and pepse means digestion. Therefore, dyspepsia is a poor digestion. From the clinical point of view, dyspepsia corresponds to a range of symptoms originated from gastroduodenal, like pain, heartburn or epigastric discomfort, postprandial fullness or early fullness related or not to nausea, vomiting, upper abdominal distension. So, this explain that a functional or organic decline situated at the epigastric area and it is originated from gastroduodenal...

Opioids are widely used for the treatment of malignant and non-malignant pains. These medications are accompanied by adverse effects, in particular gastrointestinal symptoms known as opioid bowel dysfunction [OBD]. The most common symptom of OBD is refractory constipation that is usually stable regardless of the use of laxatives. Narcotic bowel syndrome [NBS] is a subset of OBD described as ambiguous chronic pain aggravated by continual or increased opioid use for pain relief. Pathophysiology of these disorders are not definitely disentangled. Some challenging hypothesis have been posed leading to specific management in order to mitigate the adverse effects. This article is a review of the literature on the prevalence, pathophysiology and management of OBD and NBS.

OBJETIVOS: Abordar as peculiaridades do controle neuronal digestório e descrever as principais manifestações digestórias na paralisia cerebral, atentando-se à importância do diagnóstico precoce para intervenção interdisciplinar eficaz. FONTES DOS DADOS: Revisão sistemática de 1997 a 2012 das bases de dados MEDLINE, LILACS, SciELO e Cochrane Library. Incluem-se 70 artigos, como revisões relevantes, estudos observacionais, ensaios clínicos e estudos de prevalência. Excluíram-se pesquisas qualitativas. Os termos pesquisados foram: paralisia cerebral, disfagia, doença do refluxo gastroesofágico, constipação intestinal, infecção respiratória e gastrostomia. SÍNTESE DOS DADOS: O controle adequado do trato digestório depende do funcionamento e integridade do sistema nervoso. Como indivíduos portadores de paralisia cerebral possuem anormalidades estruturais evidentes no sistema nervoso central e periférico, estão mais propensos a desenvolver distúrbios do trato digestório, com repercussões nutricionais. As alterações vão desde imaturidade neurológica até interferência do estado de humor e capacitação dos cuidadores. Trata-se, portanto, de etiologia multifatorial. As desordens digestórias mais prevalentes são disfagia, doença do refluxo gastroesofágico e constipação intestinal, com consequentes quadros de infecções respiratórias de repetição e repercussão deletéria no estado nutricional. CONCLUSÕES: Indivíduos com paralisia cerebral apresentam alterações neurológicas do controle do sistema digestório, portanto manifestações digestórias são frequentes. As questões abordadas são fundamentais para profissionais das equipes interdisciplinares que atendem indivíduos com paralisia cerebral acerca da importância da anamnese ampla, exame clínico e complementar detalhado que incluam investigação das desordens gastrointestinais associadas e suas consequências. A detecção precoce dessas alterações digestórias pode respaldar medidas de reabilitação mais eficientes no sentido de melhoria da qualidade de vida desses indivíduos.
OBJECTIVES: To examine the neural control of digestive tract and describe the main gastrointestinal disorders in cerebral palsy (CP), with attention to the importance of early diagnosis to an efficient interdisciplinary treatment. SOURCES: Systematic review of literature from 1997 to 2012 from Medline, Lilacs, Scielo, and Cochrane Library databases. The study included 70 papers, such as relevant reviews, observational studies, controlled trials, and prevalence studies. Qualitative studies were excluded. The keywords used were: cerebral palsy, dysphagia, gastroesophageal reflux disease, constipation, recurrent respiratory infections, and gastrostomy. SUMMARY OF THE FINDINGS: The appropriate control of the digestive system depends on the healthy functioning and integrity of the neural system. Since CP patients have structural abnormalities of the central and peripheral nervous system, they are more likely to develop eating disorders. These range from neurological immaturity to interference in the mood and capacity of caregivers. The disease has, therefore, a multifactorial etiology. The most prevalent digestive tract disorders are dysphagia, gastroesophageal reflux disease, and constipation, with consequent recurrent respiratory infections and deleterious impact on nutritional status. CONCLUSIONS: Patients with CP can have neurological abnormalities of digestive system control; therefore, digestive problems are common. The issues raised in the present study are essential for professionals within the interdisciplinary teams that treat patients with CP, concerning the importance of comprehensive anamnesis and clinical examination, such as detailed investigation of gastrointestinal disorders. Early detection of these digestive problems may lead to more efficient rehabilitation measures in order to improve patients' quality of life.

OBJETIVOS: Apresentar a frequência, os principais fatores causadores dos sintomas gastrointestinais em pacientes portadores do diabetes melito e controvérsias quanto à sua ocorrência em crianças e adolescentes. FONTES DOS DADOS: Revisão não sistemática nas bases de dados MEDLINE/PubMed e SciELO (1983-2011), além de capítulos de livros relevantes. Foram selecionados os artigos mais atuais e representativos do tema. SÍNTESE DOS DADOS: A prevalência do diabetes melito vem aumentando ao longo dos anos em vários países do mundo. No sistema digestório, é conhecida a ocorrência de complicações do diabetes melito, entre elas os sintomas gastrointestinais (náuseas, vômitos, dor abdominal, azia, disfagia, constipação, diarreia e incontinência fecal). A patogênese das alterações das funções gastrointestinais no diabetes melito está ainda sob investigação, e o papel do sistema nervoso entérico e seus neurotransmissores tem ganhado significância. Em decorrência do comprometimento do sistema digestório, com danos ao sistema nervoso entérico, portadores do diabetes melito podem apresentar quadros específicos de distúrbios de motilidade, alguns de grande relevância clínica, como gastroparesia diabética, constipação e diarreia. A disfunção deste sistema contribui para aumentar a morbidade desta doença e piora a qualidade de vida de seus portadores. CONCLUSÕES: O diabetes melito, ao longo dos anos, afeta o sistema digestório. Por ser uma condição que piora a qualidade de vida dos portadores e também pode indicar complicação da doença, deve ser valorizada no acompanhamento e tratamento do paciente com diabetes melito. Na infância e na adolescência, ainda existem poucos estudos que abordam o problema.
OBJECTIVES: To present the main mechanisms that cause gastrointestinal symptoms in patients with diabetes mellitus, their frequency, and controversies as to their occurrence in children and adolescents. SOURCES: Non-systematic review of the literature conducted in the MEDLINE/PubMed and SciELO databases (1983-2011), as well as relevant book chapters. The most relevant and up-to-date articles on the topic were selected. SUMMARY OF THE FINDINGS: Prevalence of diabetes mellitus has been increasing over the years in many countries. The complications caused by this disease in the digestive system, such as gastrointestinal symptoms (nausea, vomiting, abdominal pain, heartburn, dysphagia, constipation, diarrhea, and fecal incontinence) are well known. The pathogenesis of changes in the gastrointestinal functions in patients with diabetes mellitus is still being investigated at the same time as the role of the enteric nervous system and its neurotransmitters has gained significance. As a consequence of the complications in the digestive system, which damage the enteric nervous system, patients with diabetes mellitus may have specific gastrointestinal motility disorders, some of which may be of great relevance, such as diabetic gastroparesis, constipation, and diarrhea. Gastrointestinal dysfunction increases the morbidity of diabetes mellitus and worsens the quality of life of diabetic individuals. CONCLUSIONS: There are few studies addressing these problems in childhood and adolescence. Diabetes mellitus affects the digestive system over the years. Because this condition worsens the quality of life of diabetic individuals and leads to complications, attention must be paid to gastrointestinal symptoms when treating patients with diabetes mellitus.

The migrating motor complex (MMC) occurs in most mammals and birds and is organized during the fetal life. In some species, like ruminants and other herbivores, it is not abolished by feeding but its character and controlling mechanisms do not vary considerably from other animal species. However, the mechanisms controlling the MMC are complex and incompletely recognized. The central nervous system exerts rather modulatory effects upon the MMC and the role of the enteric nervous system in the initiation and propagation of the MMC is crucial. The hormones appear mainly to disrupt and convert the MMC cycle into the fed pattern. Several types of the disturbances of the MMC cycle and its phases have been described in various pathophysiological conditions. However, it can be more suitable to identify and describe the given MMC abnormality than to establish the rules of the MMC behavior in the course of the gastrointestinal diseases.

O acometimento patológico do sistema nervoso no diabetes melito é muito amplo e, freqüentemente, bastante grave. A prevalência de neuropatia diabética atinge níveis elevados com a evolução temporal do diabetes, chegando, geralmente, a freqüências acima de 50 por cento de lesão neurológica em diferentes grupos de pacientes analisados em nosso meio e no exterior. A lesão neurológica nesta situação patológica é extensa no organismo humano diabético, envolvendo amplamente todo o sistema nervoso periférico nos seus componentes sensitivo-motor e autonômico: com clínica característica e concordante com as hipóteses patogênicas de natureza metabólica e/ou microvascular. O sistema nervoso autonômico é o elemento fundamental na regulação da função da maior parte dos sistemas ou órgãos no organismo, portanto, a sua lesão pode trazer importantes alterações para as funções cardiovascular, respiratória, digestiva, urinária e genital, podendo influir na função vital de alguns desses órgãos ou sistemas. Este artigo aborda as alterações decorrentes da lesão do sistema nervoso autonômico, especialmente nos pacientes diabéticos tipo 1, procurando dimensionar o risco de morbimortalidade.
The pathological alteration of the nervous system in diabetic patients is extensive and frequently severe. The prevalence of the diabetic neuropathy reach high levels with the evolution of the diabetes, often showing frequencies higher than 50 percent in several groups of patients. The neurological lesion in this pathological situation is extensive in the diabetic patient, including widely the peripheral nervous system with its components sensory, motor and autonomic: with typical symptoms and in accordance with the pathogenesis of metabolic origin and/or microvascular disease. The autonomic nervous system is a main regulator of many systems in the human body. Then its lesion can promote significant alterations in the function of the cardiovascular, respiratory, gastrointestinal, urogenital system, that can be related to increased motality. This review anlyses the abnormalities related to lesion of the autonomic nervous system, particularly in type 1 diabetic patients, trying to characterize the risk of morbidity and mortality.

La infección por Helicobacter pylori es una de las infecciones de mayor prevalencia a nivel mundial, la mayoría de los infectados son asintomáticos, llegando a presentar síntomas gastrointestinales sólo una pequeña proporción. Su mecanismo fisopatogénico es múltiple, involucrando factores de virulencia y la producción de ciertas proteínas, enzimas, citotoxinas y hemolisinas. El método diagnóstico con mayor sensibilidad y especificidad en nuestro medio es el histológico; no obstante recientemente se han desarrollado métodos no invasivos igualmente sensibles. El tratamiento de H. pylori se lleva a cabo con antibióticos y medicamentos bloqueadores del ácido gástrico. Se emplean asociaciones de fármacos a distintas dosis y durante diferentes períodos de tiempo, con variaciones en el porcentaje de eficacia. En este artículo se revisan los aspectos generales de la infección por H: pylori, así como su diagnóstico y terapéutica
