de la deglución, los cuales representan todas las alteraciones del proceso fisiológico encargado de llevar el alimento desde la boca al esófago y después al estómago, salvaguardando siempre la protección de las vías respiratorias. OBJETIVO. Definir el manejo óptimo, de la disfagia en pacientes con antecedente de infección severa por COVID-19. METODOLOGÍA. Se realizó una revisión de la literatura científica en las bases de datos PubMed y Elsevier que relacionan el manejo de la disfagia y pacientes con antecedente de infección severa por SARS-CoV-2. Se obtuvo un universo de 134 artículos que cumplieron los criterios de búsqueda. Se seleccionaron 24 documentos, para ser considerados en este estudio. RESULTADOS. La incidencia de disfagia posterior a infección severa por SARS-CoV-2 fue del 23,14%, siendo la disfagia leve la más frecuente 48,0%. Los tratamientos clínicos más empleados en el manejo de la disfagia fueron rehabilitación oral y cambio de textura en la dieta en el 77,23% de los casos, mientras que el único tratamiento quirúrgico empleado fue la traqueotomía 37,31%. Un 12,68% de pacientes recuperó su función deglutoria sin un tratamiento específico. La eficacia de los tratamientos clínicos y quirúrgicos en los pacientes sobrevivientes de la infección severa por SARS-CoV-2 fue del 80,68%, con una media en el tiempo de resolución de 58 días. CONCLUSIÓN. La anamnesis es clave para el diagnóstico de disfagia post COVID-19. El tratamiento puede variar, desde un manejo conservador como cambios en la textura de la dieta hasta tratamientos más invasivos como traqueotomía para mejorar la función deglutoria.

INTRODUCTION. The difficulty to swallow or dysphagia is included within the problems of swallowing, which represent all the alterations of the physiological process in charge of carrying the food from the mouth to the esophagus, and then to the stomach, always taking into account the protection of the airways. OBJECTIVE. To define the optimal management, both clinical and surgical, for the adequate treatment of dysphagia produced as a consequence of severe SARS-CoV-2 infection. METHODOLOGY. A review of the scientific literature was carried out using both PubMed and Elsevier databases, which relate the management of dysphagia and patients with a history of severe SARS-CoV-2 infection. RESULTS. The incidence of dysphagia following severe SARS-CoV-2 infection was of 23,14%, with mild dysphagia being the most frequent 48,00%. The most frequently used clinical treatments for dysphagia management were oral rehabilitation and change in dietary texture in 77,23% of cases, while tracheotomy was the only surgical treatment used 37,31%. A total of 12,68% of patients recovered their swallowing function without specific treatment. The efficacy of clinical and surgical treatments in survivors of severe SARS-CoV-2 infection was 80,68%, with a mean resolution time of 58 days. CONCLUSION. An adequate medical history is key to the diagnosis of post-COVID-19 dysphagia. Treatment can range from conservative management such as changes in diet texture to more invasive treatments such as tracheotomy to improve swallowing function.

Prevalencia y factores de riesgo del comportamiento anormal estereotipado aerofagia en el caballo criollo colombiano / Prevalence and Risk Factors of Abnormal Stereotyped Crib-Biting Behavior in the Colombian Creole Horse

RESUMEN La aerofagia es la estereotipia clásica más común en los equinos, con una etiología poca entendida; sin embargo, se reconoce por ser de naturaleza multifactorial. Además, se ha asociado con efectos negativos sobre la salud de los equinos portadores. El objetivo de este estudio fue describir los factores de riesgo y la frecuencia de presentación de la aerofagia en una población de caballos criollos colombianos (CCC). Fueron encuesta-dos 42 criaderos, entre los que se presentó un total de 1063 CCC (488 machos y 575 hembras). De esta población, el 5,27% (56 animales) fue plenamente identificado con aerofagia. Esta prevalencia fue superior a la mayoría de otros reportes de Sur América. La aerofagia, posiblemente obedeció tanto a factores inherentes al animal como a factores externos relacionados con el manejo; sin embargo, se requiere el diseño de estudios longitudinales sobre prácticas de manejo y de líneas dentro de la raza para cuantificar y validar la información relacionada con la posible predisposición genética o racial a la aerofagia y a otras estereotipias y comportamientos anormales observados en estos animales.

ABSTRACT Crib-biting is the most common classic stereotype in equines, with a poorly understood etiology; however, it is recognized for being multifactorial in nature. Furthermore, it has been associated with negative effects on the health of horses. The objective of this study was to describe the risk factors and the frequency of presentation of crib-biting in a population of Colombian Creole Horses (CCC by its Spanish acronym). We surveyed Forty-two properties, which meant a total of 1063 CCC (488 males and 575 females). Of this population, 5,27% (56 animals) were fully identified with crib-biting. This prevalence was higher than most other reports in South America. Crib-biting is possibly due to both inherent of the animal and external factors related to management; however, the design of longitudinal studies on management practices and genetic lines within the breed is required to quantify and validate the information related to the possible genetic or racial predisposition for this and other stereotypes and abnormal behaviors observed in horses.

A single-center retrospective analysis of 46 children with aerophagia / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features of aerophagia in children.@*MEYJODS@#A retrospective analysis was performed on the medical data of 46 children with aerophagia who were diagnosed and treated in Children's Hospital Affiliated to Nanjing Medical University from October 2011 to September 2019.@*RESULTS@#Among these 46 children, 15 (33%) had Tourette syndrome. Abdominal distension was the most common symptom and was observed in 45 children (98%). The 24-hour esophageal multichannel intraluminal impedance monitoring showed a mean number of 341 times of air swallowing and a mean number of 212 times of gas reflux, and 95% of gas refluxes occurred in the upright body position. Compared with those without Tourette syndrome, the children with Tourette syndrome had a significantly higher incidence rate of air swallowing symptoms (67% vs 6%, P<0.001), but there were no significant differences in other symptoms and the results of 24-hour esophageal impedance. Dietary adjustment, psycho-behavioral therapy, and drug intervention significantly improved the scores of clinical symptoms and quality of life, among which psycho-behavioral therapy was an important intervention measure.@*CONCLUSIONS@#Some children with aerophagia may have Tourette syndrome, and such children are more likely to have air swallowing symptoms. Psycho-behavioral therapy is one of the most important treatment methods, and children with aerophagia tend to have a good prognosis after treatment.

Encarceramento do intestino delgado em forame epiploico em equinos com hábito de aerofagia: relato de caso / Entrapment of the small intestine in the epiploic foramen in crib-biting horses: case report

São relatados quatro casos de encarceramento de forame epiploico (EFE), entre os casos: três machos e uma fêmea; dois da raça Quarto de Milha, um SRD e um Brasileiro de Hipismo; idade média de 11 anos; altura média de cernelha de 160,5cm; massa corporal média de 465kg. Todos os animais possuíam o hábito de aerofagia. A presença de refluxo enterogástrico e intestino delgado distendido à palpação transretal foi variável na dependência do segmento intestinal aprisionado. À laparotomia exploratória constataram-se: dois casos de aprisionamento jejunoileal; um de jejuno; e o outro de íleo. Todos os animais apresentaram EFE da esquerda para a direita, representando o sentido horário. Apenas o animal que apresentava o íleo aprisionado sobreviveu; os demais foram submetidos à eutanásia no período transoperatório devido à extensa isquemia intestinal e às lesões vasculares decorrentes da manobra de redução. A aerofagia é o fator de risco que apresenta maior correlação positiva com o EFE, fato corroborado pelos casos apresentados. Apesar de ser descrito um bom prognóstico para o EFE na literatura, foi obtido um desfecho ruim entre os casos atendidos, e salienta-se que a extensão da lesão e o sangramento da veia porta no transoperatório contribuíram para esse resultado.(AU)

Four cases of epiploic foramen entrapment (EFE) are reported. Among the cases, three males and one female, two Quarter Horses, one mixed breed and one Brazilian Equestrian, aged between 3 to 20 years, mean 11 years. The average height was 160.5cm and 465kg. All horses had a previous record of crib-biting habit. The presence of enterogastric reflux and small intestine distended loops in transrectal palpation was variable in dependence of the trapped segment. In surgical exploration were identified two cases of jejunum and ileum entrapped, one of the ileum and one of jejunum. All animals showed EFE from left to right. The horse that had trapped the ileum has survived. The others were euthanized due to the extent of injury or rupture of large vessels during surgical reduction. Although there are many notes of possible risk factors for EFE occurrence, cribbing is the risk factor that has the highest positive correlation with EFE. This appointment was confirmed by the cases presented. Despite being described a good prognosis for the EFE, a bad outcome was achieved among the cases, and stresses that the extent of the injury and bleeding from the portal vein contributed to this outcome.(AU)

EFFECT OF GUM CHEWING ON AIR SWALLOWING, SALIVA SWALLOWING AND BELCHING / Efeito da goma de mascar na deglutição de ar, deglutição de saliva e na eructação

BackgroundEructation is a physiologic event which allows gastric venting of swallowed air and most of the time is not perceived as a symptom. This is called gastric belching. Supragastric belching occurs when swallowed air does not reach the stomach and returns by mouth a short time after swallowing. This situation may cause discomfort, life limitations and problems in daily life.ObjectiveOur objective in this investigation was to evaluate if gum chewing increases the frequency of gastric and/or supragastric belches.MethodsEsophageal transit of liquid and gas was evaluated by impedance measurement in 16 patients with complaint of troublesome belching and in 15 controls. The Rome III criteria were used in the diagnosis of troublesome belching. The esophageal transit of liquid and gas was measured at 5 cm, 10 cm, 15 cm and 20 cm from the lower esophageal sphincter. The subjects were evaluated for 1 hour which was divided into three 20-minute periods: (1) while sitting for a 20-minute base period; (2) after the ingestion of yogurt (200 mL, 190 kcal), in which the subjects were evaluated while chewing or not chewing gum; (3) final 20-minute period in which the subjects then inverted the task of chewing or not chewing gum. In gastric belch, the air flowed from the stomach through the esophagus in oral direction and in supragastric belch the air entered the esophagus rapidly from proximal and was expulsed almost immediately in oral direction. Air swallows were characterized by an increase of at least 50% of basal impedance and saliva swallow by a decrease of at least 50% of basal impedance, that progress from proximal to distal esophagus.ResultsIn base period, air swallowing was more frequent in patients than in controls and saliva swallowing was more frequent in controls than in patients. There was no difference between the medians of controls and patients in the number of gastric belches and supragastric belches. In six patients, supragastric belches were seen at least once during the 20-minute base period. None of the controls had supragastric belches. In the control group, the ingestion of yogurt caused no significant alteration in the number of air swallows, saliva swallows, gastric belches and supragastric belches. In the patient group, there was an increase in the number of air swallows. If the subjects were chewing gum during this 20-minute period, there was an increase in the number of saliva swallows in both groups, without alterations of the number of air swallow, gastric belches and supragastric belches. There was no alteration in the number of the saliva swallows, air swallows, gastric belches and supragastric belches in both groups for subjects who did not chew gum in the 20-40 minute period after yogurt ingestion. When the subjects were chewing the gum, there was an increase in saliva swallows in the control and patients groups and in air swallows in the patients group.ConclusionGum chewing causes an increase in saliva swallowing in both patients with excessive belching and in controls, and an increase in air swallowing in patients with excessive belching 20 minutes after yogurt ingestion. Gum chewing did not increase or decrease the frequency of gastric or supragastric belches.

ContextoEructação é um evento fisiológico que permite a eliminação de gás presente no estômago, geralmente não percebida como sintoma, situação identificada como eructação gástrica. Eructação supragástrica ocorre quando o ar deglutido não vai ao estômago, mas retorna do esôfago imediatamente após ser deglutido; situação que causa desconforto e limitações ao paciente.ObjetivoO objetivo desta investigação foi avaliar se goma de mascar aumenta a frequência de eructação gástrica e/ou supragástrica.MétodosO trânsito de líquido e gás foi avaliado por impedância in 16 pacientes com queixas de eructação excessiva e 15 controles. O diagnóstico de eructação excessiva foi feito tendo em consideração os critérios descritos no Roma III. O trânsito pelo esôfago foi medido por sensores de impedância localizados a 5 cm, 10 cm, 15 cm e 20 cm do esfíncter inferior do esôfago. Os indivíduos foram avaliados sentados em uma cadeira durante um período basal de 20 minutos, outro período de 20 minutos após a ingestão de iogurte (200 mL, 190 kcal), mastigando ou não goma de mascar, e em outro período por mais 20 minutos no qual invertiam o fato de mastigarem ou não goma de mascar. Na eructação gástrica o ar vinha do estômago em direção proximal, e na eructação supragástrica o ar entrou no esôfago e foi imediatamente eliminado em direção proximal. A deglutição de ar foi caracterizada pelo aumento em pelo menos 50% do valor da impedância e a deglutição de saliva pela diminuição em pelo menos 50% do valor da impedância, que progredia da parte proximal do esôfago para a parte distal.ResultadosNo período basal a deglutição de ar foi mais frequente nos pacientes do que nos controles, e a deglutição de saliva mais frequente nos controles do que nos pacientes. Não houve diferenças na mediana entre os resultados de controles e pacientes no número de eructações gástricas e supragástricas. Em seis pacientes ocorreram eructações supragástricas, o que não aconteceu em nenhum controle. Entre os controles a ingestão de iogurte não alterou a frequência de deglutição de ar, deglutição de saliva, eructações gástricas e eructações supragástricas. No grupo de pacientes houve aumento da deglutição de ar. Mastigar a goma durante este período causou aumento da deglutição de saliva, nos dois grupos, sem alterações na frequência de deglutição de ar, eructação gástrica e eructação supragástrica. No período entre 20 e 40 minutos após a ingestão do iogurte, se a pessoa não mascava a goma, não havia mudança na frequência de deglutição de saliva, deglutição de ar, eructações gástricas e eructações supragástricas. Quando a pessoa mascava a goma, houve aumento da deglutição de saliva nos dois grupos e de deglutição de ar no grupo de pacientes.ConclusãoGoma de mascar causa aumento da deglutição de saliva em pacientes com eructações excessivas e controles, e aumento da deglutição de ar em pacientes 20 minutos após a ingestão de iogurte. Goma de mascar não aumenta ou diminui a frequência de eructação gástrica ou eructação supragástrica.

Aerofagia patológica: uma causa rara de distensão abdominal crônica / Pathologic aerophagia: a rare cause of chronic abdominal distension

Objetivo:Descrever o caso de uma adolescente com aerofagia patológica, uma doença rara causada pela deglutição excessiva e inapropriada de ar, e revisar o tratamento e os diagnósticos diferenciais.Descrição do caso:Menina de 11 anos portadora de retardo mental e cegueira, apresentava problemas comportamentais associados a retardo do desenvolvimento, foi consultada por distensão abdominal persistente por oito meses. Sua história pregressa incluía uma fundoplicatura à Nissen. Tomografia e radiografias abdominais mostravam distensão difusa do trato digestivo por ar, incluindo cólon e delgado. Doença de Hirschsprung foi excluída. A distensão persistiu mesmo após o controle da constipação e era mínima de manhã e máxima à noite. Ruídos audíveis e repetitivos de deglutição de ar foram observados e auscultados. A criança foi tratada farmacologicamente com o diagnóstico de aerofagia patológica associado a distúrbio obsessivo compulsivo, sem sucesso. A paciente foi submetida a gastrostomia descompressiva endoscopia e manteve nutrição oral.Comentários:A aerofagia patológica é uma doença rara e autolimitada em crianças, mas pode ser um problema grave e persistente naquelas com problemas neuropsiquiátricos, nas quais pode causar complicações sérias. Os tratamentos comportamentais e farmacológicos têm pouco sucesso nesse grupo. Casos graves podem precisar de tratamento cirúrgico, principalmente gastrostomia descompressiva.

Objective:To describe an adolescent with pathologic aerophagia, a rare condition caused by excessive and inappropriate swallowing of air and to review its treatment and differential diagnoses.Case description:An 11-year-old mentally impaired blind girl presenting serious behavior problems and severe developmental delay with abdominal distension from the last 8 months. Her past history included a Nissen fundoplication. Abdominal CT and abdominal radiographs showed diffuse gas distension of the small bowel and colon. Hirschsprung's disease was excluded. The distention was minimal at the moment the child awoke and maximal at evening, and persisted after control of constipation. Audible repetitive and frequent movements of air swallowing were observed. The diagnosis of pathologic aerophagia associated to obsessive-compulsive disorder and developmental delay was made, but pharmacological treatment was unsuccessful. The patient was submitted to an endoscopic gastrostomy, permanently opened and elevated relative to the stomach. The distention was resolved, while maintaining oral nutrition.Comments:Pathologic aerophagia is a rare self-limiting condition in normal children exposed to high levels of stress and may be a persisting problem in children with psychiatric or neurologic disease. In this last group, the disease may cause serious complications. Pharmacological and behavioral treatments are ill-defined. Severe cases may demand surgical strategies, mainly decompressive gastrostomy.

A Case of Aerophagia Diagnosed by Multichannel Intraluminal Impedance Monitoring / 대한소화기학회지

Aerophagia is a disorder caused by abnormal accumulation of air in the gastrointestinal tract as a result of repetitive and frequent inflow of air through the mouth. For the diagnosis of this condition, it is difficult to objectively measure the air swallowing. However, multichannel intraluminal impedance monitoring facilitates the differential diagnosis between normal air swallowing and pathologic aerophagia, and can aid in the determination of the frequency and amount of air swallowed. In this report, in addition to a literature review, we describe a case of 36-year-old man with abdominal distension who was diagnosed with aerophagia using esophageal impedance monitoring and was treated with clonazepam.

Clonazepam Treatment of Pathologic Aerophagia in Children with Mental Retardation / 대한소아소화기영양학회지

PURPOSE: Pathologic aerophagia (PA) may lead to bowel perforation or volvulus in mentally retarded patients. The authors investigated the effects of clonazepam on the management of PA in children with severe to profound mental retardation (MR). METHODS: This study was undertaken as a retrospective case analysis of 21 PA patients with MR who were followed for over 12 months and diagnosed as having PA. Patients were assigned to two management groups, that is, to a clonazepam randomized open-labeled, treatment group or a reassurance group. The following were recorded and analyzed; age, response, remission rate to clonazepam treatment, and the side effect of clonazepam. It was defined positive response (response+) as being symptom-free for a whole week within 1 month of commencing treatment and remission(+) as being symptom-free for a whole month within 6 months of treatment. RESULTS: The average age of the 21 PA children with MR was 10 years and 13 patients were female. Symptom duration before diagnosis of PA was 7 months. Clinical features of the clonazepam-trial group (n=11) and the reassurance group (n=10) were non-significantly different. Response(+) was achieved by 2 patients (18.2%) in the clonazepam-trial group and by no patient in the reassurance group. Remission(+) was achieved by 6 patients (54.5%) in the clonazepam-trial group and by one patient (10%) in the reassurance group (p=0.040). CONCLUSION: When PA children with MR with severe bowel distention are considered for surgical treatment to prevent acute abdomen, a trial of clonazepam could be recommended.

Belching (Eructation) / 대한소화기학회지

Belching is a normal physiological function that may occur when ingested air accumulated in the stomach is expelled or when food containing air and gas produced in the gastrointestinal tract is expelled. Excessive belching can cause patients to complain of abdominal discomfort, disturbed daily life activities, decreased quality of life and may be related to various gastrointestinal disorders such as gastroesophageal reflux disease, functional dyspepsia, aerophagia and rumination syndrome. Belching disorders can be classified into aerophagia and unspecified belching disorder according to the Rome III criteria. Since the introduction of multichannel intraluminal impedance monitoring, efforts are being made to elucidate the types and pathogenic mechanisms of belching disorders. Treatment modalities such as behavioral therapy, speech therapy, baclofen, tranquilizers and proton pump inhibitors can be attempted, but further investigations on the effective treatment of belching disorders are warranted.

Aerofagia em equinos: revisão de literatura / Aerofagia en equinos: revisión de literatura / Windsucking in horses: a literature review

São observados em diversos cavalos, alojados em baias, tendência a executarem uma variedade de atividades aparentemente sem função e comportamentos repetitivos, denominados estereotipias. Destes, a aerofagia é um vício geralmente adquirido, relativamente comum em equinos, sem distinção de raça e sexo, no qual o animal, apoiando os dentes incisivos em um objeto fixo, realiza um movimento de arqueamento e flexão do pescoço, conseguindo engolir certa quantidade de ar. Na aerofagia com o tempo ocorre desgaste excessivo dos dentes incisivos, perda de peso, hipertrofia dos músculos ventrais do pescoço, especialmente do músculo esternocefálico, cólicas por ulceração gástrica, encarceiramento do forame epiplóico e meteorismos ocasionais além da desvalorização do animal. Projetar adequadamente as baias optando por evitar superfícies de apoio, uso de eletrochoque, utilização de colar eletrônico para adestramento de cães, uso de colar de pescoço para evitar o movimento de deglutição, colocar o animal em companhia de outros em piquetes, aumentar o número de exercícios e fornecer maior quantidade de feno ou gramíneas verdes, são métodos que ajudam na prevenção dos episódios. Diante do insucesso de técnicas conservativas, três procedimentos cirúrgicos são descritos para o controle da aerofagia. São descritas também diversas modalidades terapêuticas, que podem reduzir a incidência dos episódios, embora melhores resultados resultem de cuidados profiláticos, antes dos vícios se estabelecerem.(AU)

In several horses housed in stalls, a tendency to perform a variety of apparently functionless activities and repetitive behaviors called stereotypies can be observed. Among these, windsucking is an addiction usually acquired that is relatively common in horses, regardless of breed or gender, in which the animal, holding its incisor teeth onto a fixed object, performs the movement of bending and flexing the neck, managing to swallow a certain amount of air. With time, windsucking causes excessive wear of the incisor teeth, weight loss, hypertrophy of the ventral neck muscles, especially the esternocephalic muscle, cramps due to gastric ulceration, trapping of the epiploic foramen and occasional meteorisms, as well as devaluating the animal. Properly designing the stalls, opting to avoid supporting surfaces, the use of electroshock, the use of electronic collar for dog training, the use of neck collar to prevent swallowing movements, placing the animal with others in paddocks, increasing the number of exercises and providing greater amount of hay or green grass are methods that help preventing these episodes. Given the failure of conservative techniques, three surgical procedures are described for the control of windsucking. Several therapeutic modalities are also described, which can reduce the incidence of the episodes, although better results arise from prophylactic care, before these addictions are established.(AU)

Dado el fracaso de las técnicas conservadoras, tres procedimientos quirúrgicos se describen para el control de aerofagia. También se describen varias modalidades terapéuticas que pueden reducir la incidencia de episodios, aunque los mejores resultados surgen de la atención profiláctica y antes que se establezcan los vicios.(AU)

Sinais e sintomas da disfunção autônoma em indivíduos disfônicos / Signs and symptoms of autonomic dysfunction in dysphonic individuals

OBJETIVO: Verificar a ocorrência de sinais e sintomas da disfunção do sistema nervoso autônomo em indivíduos com disfonia comportamental e compará-la com resultados obtidos por indivíduos sem queixa vocal. MÉTODOS: Participaram 128 indivíduos adultos, com idades entre 14 e 74 anos, que foram divididos em dois grupos: disfonia comportamental (61 sujeitos) e sem queixa vocal (67 sujeitos). Foi aplicado o Protocolo de Disfunção Autônoma contendo 46 questões, sendo 22 relacionadas ao sistema nervoso autônomo e sem relação direta com a voz, 16 relacionadas tanto ao sistema nervoso autônomo quanto à voz, seis questões não-relevantes e duas questões de confiabilidade. RESULTADOS: Nas questões relacionadas à voz, como pigarros constantes, necessidade de engolir frequentemente, cansaço ao falar e dor de garganta, houve maior ocorrência de alterações neurovegetativas no grupo com disfonia comportamental. Nas questões sem relação direta com a voz, os indivíduos disfônicos apresentaram maior ocorrência de três dos 22 sintomas: gases, zumbido e engole ar enquanto fala. Os dois grupos apresentaram resultados semelhantes nas questões consideradas não relevantes ao sistema nervoso autônomo. As questões de confiabilidade necessitaram de reformulação. CONCLUSÃO: Indivíduos com disfonia comportamental apresentam maior ocorrência de sintomas neurovegetativos, principalmente daqueles que possuem relação direta com a voz. Tais resultados indicam maior labilidade do sistema nervoso autônomo nesses indivíduos.

PURPOSE: To verify the occurrence of signs and symptoms of autonomic nervous system dysfunction in individuals with behavioral dysphonia, and to compare it with the results obtained by individuals without vocal complaints. METHODS: Participants were 128 adult individuals with ages between 14 and 74 years, divided into two groups: behavioral dysphonia (61 subjects) and without vocal complaints (67 subjects). It was administered the Protocol of Autonomic Dysfunction, containing 46 questions: 22 related to the autonomic nervous system and had no direct relationship with voice, 16 related to both autonomic nervous system and voice, six non-relevant questions, and two reliability questions. RESULTS: There was a higher occurrence of reported neurovegetative signs in the group with behavioral dysphonia, in questions related to voice, such as frequent throat clearing, frequent swallowing need, fatigability when speaking, and sore throat. In questions not directly related to voice, dysphonic individuals presented greater occurrence of three out of 22 symptoms: gas, tinnitus and aerophagia. Both groups presented similar results in questions non-relevant to the autonomic nervous system. Reliability questions needed reformulation. CONCLUSION: Individuals with behavioral dysphonia present higher occurrence of neurovegetative signs and symptoms, particularly those with direct relationship with voice, indicating greater lability of the autonomic nervous system in these subjects.

44 años de avances en Etiopatogenia, Diagnóstico y Tratamiento del Síndrome Flatulencia / Forty-four years of advances in pathogenesis, diagnosis and treatment of Flatulence Syndrome

En el presente artículo, el autor recuerda trabajos de investigación realizados, desde hace cuarenticuatro años, para aclarar la etiopatogenia y mejorar el diagnóstico y tratamiento del síndrome flatulencia.

In the present paper, the author reminds investigations performed, since forty-four years ago, to clarify the ethiopathogenesis and to improve the diagnosis and treatment of the flatulence syndrome.

Clonazepam Treatment of Pathologic Childhood Aerophagia with Psychological Stresses

The treatment of pathologic aerophagia has rarely been discussed in the literature. In this retrospective study, the authors investigated the effects of clonazepam on the management of pathologic childhood aerophagia (PCA) with psychological stresses (PS), but not with mental retardation. Data from 22 consecutive PCA patients with PS (aged 2 to 10 yr), who had been followed up for over 1 yr, were reviewed. On the basis of videolaryngoscopic views, the authors observed that the pathology of aerophagia was the result of reflex-induced swallowing with paroxysmal openings of the upper esophageal sphincter due to unknown factors and also observed that these reflex-induced openings were subsided after intravenous low dose benzodiazepine administration. Hence, clonazepam was administered to treat paroxysmal openings in these PCA patients with PS. Remission positivity was defined as symptom-free for a consecutive 1 month within 6 months of treatment. The results of treatment in 22 PCA patients with PS were analyzed. A remission positive state was documented in 14.3% of PCA patients managed by reassurance, and in 66.7% of PCA patients treated with clonazepam (p=0.032). Thus, clonazepam may produce positive results in PCA with PS. Future studies by randomized and placebo-controlled trials are needed to confirm the favorable effect of clonazepam in PCA.

Gastric perforation in neonates: Analysis of five cases

Neonatal gastric perforation has always been a mysterious entity regarding its cause. Although some have definite causes e.g. TOP causing severe dilatation of the stomach, iatrogenic secondary to the introduction of a hard nasogastric tube but the majority have no obvious reasons. Many theories have been advocated such as gastric ischemia or aerophagia due to excessive crying. The common feature in the five cases seen at Maadi Military hospital over a period of 5 years was marked abdominal distension causing dyspnea, fortunately, all of them survived. This good survival rate in our opinion was due to the good pre and postoperative care as well as the lack of sepsis oftenly encountered with gastric juice leakage

Coração e distensão abdominal gasosa / Heart and abdominal gaseous distension

Os autores revisam suas publicações sobre a distensão abdominal gasosa em relação ao aparelho cardiovascular. Discutem os trabalhos perante a literatura, constatam que quatro grupos de pacientes podem ser estabelecidos em relação ao tema: a) pacientes híigidos, podem apresentar a pseudoangina aerofágica; b) pacientes com determinadas doenças digestivas, pioram com a distensão gasosa; c) pacientes com insuficiência coronariana, podem ter agravados os sintomas e exames com a distensão; d) pacientes com determinadas doenças digestivas e insuficiência coronariana, ainda mais padecem com a distensão abdominal. Discutem os mecanismos implicados, a importância da ansiedade no aparecimento da distensão gástrica, criando-se verdadeiro círculo vicioso se medidas terapêuticas não são estabelecidas. Concluem mostrando que o assunto merece novos estudos

A Case of Pathologic Aerophagia with Mental Retardation Managed by Percutaneous Endoscopic Gastrostomy / 대한소아소화기영양학회지

We experienced a case of pathologic aerophagia in a 10-year-old girl who has mental retardation. It was observed that the abdomen was non-distended in the morning and became maximally distended in the evening. Increased passage of flatus, but normal eructation, was noted. Roentgenographic examination showed 'esophageal air sign', abnormal air shadow on proximal esophagus adjacent to the trachea, in simple chest X-ray and visible air swallowing fluoroscopically. We tried a percutaneous endoscopic gastrostomy (PEG) to decompress swallowed air in stomach. We suggest that placement of a PEG catheter in early life, especially in mentally retarded patients, that can be used as desufflator, can prevent the complications of aerophagia.
