Prevalence of broncopulmonary and otorhinolaryngologic symptoms in children under investigation for gastroesophageal reflux disease: retrospective analysis

A Doença do Refluxo Gastroesofágico (DRGE) é uma afecção comum na infância, aumentando as evidências de que o refluxo gastroesofágico seja um cofator importante que contribui para as desordens de vias aéreas, principalmente na população pediátrica. É muito comum serem observadas manifestações em vias aéreas superiores e inferiores. Nosso objetivo é avaliar a presença de sintomas otorrinolaringológicos em crianças com idade de um a 12 anos e suspeita de doença do refluxo gastroesofágico. MATERIAIS E MÉTODO: Foram avaliados dados de prontuários de pacientes de até 12 anos submetidos à pHmetria de 24 horas de um ou dois canais, locados a 2 e 5 cm do EEI para confirmação de diagnóstico de Doença do Refluxo Gastroesofágico. RESULTADOS: Foram analisados 143 prontuários de crianças que realizaram pHmetria de 24 horas para investigação de DRGE; porém 65 foram incluídas. Os sintomas mais prevalentes nas crianças eram os broncopulmonares, encontrados em 89,2%, de sintomas nasossinusais (72,3%) , otológicos (46,1%) e de infecções de VAS de repetição (44,6%). Quando comparada a presença de cada grupo de sintomas com o resultado da pHmetria, não foi encontrada diferença significativa entre os sintomas e o resultado da pHmetria. CONCLUSÃO: DRGE pode se manifestar de diversas maneiras e os sintomas otorrinolaringológicos são frequentes em crianças.

Gastroesophageal reflux disease and vocal disturbances

CONTEXTO: A doença do refluxo gastroesofágico (DRGE) é uma doença crônica na qual o conteúdo gastroduodenal reflui para o esôfago. O quadro clínico da DRGE é usualmente referido como pirose e regurgitação (manifestações típicas). Manifestações atípicas (distúrbios da voz e asma) podem também ser referidas. OBJETIVO: Analisar os aspectos clínicos, endoscópicos, manométricos e pHmétricos de pacientes portadores da DRGE com distúrbios da voz. MÉTODO: Foram estudados 50 pacientes com a DRGE, sendo 25 com distúrbios da voz (grupo 1 - G1) e 25 sem estes sintomas (controles, grupo 2 - G2). Todos os pacientes foram submetidos a endoscopia, manometria e pHmetria esofágica (dois sensores). Os pacientes do G1 foram submetidos a videolaringoscopia. RESULTADOS: Achados endoscópicos: DRGE não-erosiva foi observada em 95% dos pacientes de G1 e em 88% de G2. Videolaringoscopia: congestão das pregas vocais, assimetria, nódulos e pólipos foram diagnosticados nos pacientes do G1. Manometria esofágica: pressão no esfíncter inferior do esôfago (mm Hg): 11,6 ± 5,2 em G1 e 14,0 ± 6,2 em G2 (P = 0,14); pressão no esfíncter superior do esôfago (mm Hg): 58,4 ± 15,9 em G1 e 69,5 ± 30,7 nos controles. Achados pHmétricos: índice de DeMeester: 34,0 ± 20,9 em G1 e 15,4 ± 9,4 em G2 (P<0,001); número de episódios de refluxo no sensor distal: 43,0 ± 20,4 em G1 e 26, 4 ± 17,2 em G2 (P<0,003); percentagem do tempo com pH esofágico menor que 4 unidades (sensor distal): 9,0% ± 6,4% em G1 e 3,4% ± 2,1% em G2 (P<0,001); número de episódios de refluxo no sensor proximal: 7,5 ± 10,9 em G1 e 5,3 ± 5,7 em G2 (P = 0,38); percentagem de tempo com pH esofágico menor que quatro unidades (sensor proximal): 1,2% ± 2,7% em G1 e 0,5% ± 0,7% em G2 (P = 0,210). CONCLUSÕES: Os aspectos clínicos, endoscópicos e manométricos em pacientes com a DRGE e distúrbios da voz não diferem dos pacientes sem estes sintomas. A intensidade do refluxo gastroesofágico é maior nos pacientes com distúrbios da voz. Os pacientes sem distúrbios da voz podem também apresentar episódios de refluxo gastroesofágico no sensor proximal.

Brazilian consensus on gastroesophageal reflux disease: Proposals for assessment, classification, and management

The Brazilian Consensus on Gastroesophageal Reflux Disease considers gastroesophageal reflux disease to be a chronic disorder related to the retrograde flow of gastroduodenal contents into the esophagus and/or adjacent organs, resulting in a variable spectrum of symptoms, with or without tissue damage. Considering the limitations of classifications currently in use, a new classification is proposed that combines three criteria - clinical, endoscopic, and pH-metric - providing a comprehensive and more complete characterization of the disease. The diagnosis begins with the presence of heartburn, acid regurgitation, and alarm manifestations (dysphagia, odynophagia, weight loss, GI bleeding, nausea and/or vomiting, and family history of cancer). Also, atypical esophageal, pulmonary, otorhinolaryngological, and oral symptoms may occur. Endoscopy is the first approach, particularly in patients over 40 yr of age and in those with alarm symptoms. Other exams are considered in particular cases, such as contrast radiological examination, scyntigraphy, manometry, and prolonged pH measurement. The clinical treatment encompasses behavioral modifications in lifestyle and pharmacological measures. Proton pump inhibitors in manufacturers' recommended doses are indicated, with doubling of the dose in more severe cases of esophagitis. The minimum time of administration is 6 wk. Patients who do not respond to medical treatment, including those with atypical manifestations, should be considered for surgical treatment. Of the complications of gastroesophageal reflux disease, Barrett's esophagus presents a potential development of adenocarcinoma; biopsies should be performed, independent of Barrett's esophagus extent or location. In this regard the designation short Barrett's is not important in terms of management and prognosis. © 2002 by Am. Coll. of Gastroenterology.

Direct restorative treatment of dental erosion caused by gastroesophageal reflux disease associated with bruxism: a case report

Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach acids are chronically regurgitated into the esophagus and oral cavity. Continual exposure of the teeth to these acids can cause severe tooth wear. Dentists are often the first healthcare professionals to diagnose dental erosion in patients with GERD. This article presents a case report of a 27-year-old male smoker with tooth wear and dentin sensitivity caused by GERD associated with bruxism. After diagnosis, a multidisciplinary treatment plan was established. The initial treatment approach consisted of medical follow-up with counseling on dietary and smoking habits, as well as management of the gastric disorders with medication. GERD management and the dental treatment performed for the eroded dentition are described, including diagnosis, treatment planning, and restorative therapy.

Prosthetic rehabilitation of a patient with gastroesophageal reflux disease: 4-year followup

The gastroesophageal reflux disease (GERD) is one of the main causes of dental erosion. The aim of this case presented is to describe the prosthetic rehabilitation of a patient with GERD after 4 years of followup. A 33-year-old male patient complained about tooth sensitivity. The lingual surface of the maxillary anterior teeth and the cusps of the upper and lower posterior teeth presented wear. It was suspected that the feeling of heartburn reported by the patient associated with the intake of sports supplements (isotonics) was causing gastroesophageal changes. The patient was referred to a gastroenterologist and was diagnosed with GERD. Dental treatment was performed with metal-free crowns and porcelain veneers after medical treatment of the disease. With the change in eating habits, the treatment of GERD and lithium disilicate ceramics provided excellent cosmetic results after 4 years and the patient reported satisfaction with the treatment.

Diagnosis and management of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is probably one of the most prevalent diseases in the world that also compromises the quality of life of the affected significantly. Its incidence in Brazil is 12%, corresponding to 20 million individuals. OBJECTIVE: To update the GERD management and the new trends on diagnosis and treatment, reviewing the international and Brazilian experience on it. METHOD: The literature review was based on papers published on Medline/Pubmed, SciELO, Lilacs, Embase and Cochrane crossing the following headings: gastroesophageal reflux disease, diagnosis, clinical treatment, surgery, fundoplication. RESULTS: Various factors are involved on GERD physiopathology, the most important being the transient lower esophageal sphincter relaxation. Clinical manifestations are heartburn, regurgitation (typical symptoms), cough, chest pain, asthma, hoarseness and throat clearing (atypical symptoms), which may be followed or not by typical symptoms. GERD patients may present complications such as peptic stenosis, hemorrhage, and Barrett's esophagus, which is the most important predisposing factor to adenocarcinoma. The GERD diagnosis must be based on the anamnesis and the symptoms must be evaluated in terms of duration, intensity, frequency, triggering and relief factors, pattern of evolution and impact on the patient's quality of life. The diagnosis requires confirmation with different exams. The goal of the clinical treatment is to relieve the symptoms and surgical treatment is indicated for patients who require continued drug use, with intolerance to prolonged clinical treatment and with GERD complications. CONCLUSION: GERD is a major digestive health problem and affect 12% of Brazilian people. The anamnesis is fundamental for the diagnosis of GERD, with special analysis of the typical and atypical symptoms (duration, intensity, frequency, triggering and relief factors, evolution and impact on the life quality). High digestive endoscopy and esophageal pHmetry are the most sensitive diagnosctic methods. The clinical treatment is useful in controlling the symptoms; however, the great problem is keeping the patients asymptomatic over time. Surgical treatment is indicated for patients who required continued drug use, intolerant to the drugs and with complicated forms of GERD.

Laryngeal and voice disorders in patients with gastroesophageal symptoms. Correlation with pH-monitoring

OBJETIVO: Investigar as alterações laríngeas e vocais em pacientes com sintomas de refluxo gastroesofágico e correlacioná-las com o exame de phmetria. MÉTODOS: Estudo prospectivo que incluiu os pacientes atendidos nos ambulatórios de Distúrbios da Voz da Faculdade de Medicina de Botucatu no período de cinco anos com sintomas vocais e gastroesofágicos. Os pacientes foram submetidos à videolaringoscopia, às análises vocais perceptivo-auditivas, a analise vocal acústica computadorizada e ao exame de pHmetria de dois canais com monitorização durante 24 horas. RESULTADOS: Foram incluídos 57 pacientes (entre 21 a 65 anos; 45 mulheres e 12 homens). Desses, 18 apresentavam pHmetria normal (31,6%) e 39 alterada (68,4%). As videolaringoscopias registraram diversas lesões laríngeas tanto nos pacientes com pHmetria normal como alterada, sendo mais relevantes neste último grupo, destacando-se a paquidermia posterior. As avaliações vocais perceptivo-auditivas identificaram alterações vocais de diversas intensidades em ambos os grupos, mais importantes nos pacientes com pHmetria alterada. Todos os parâmetros acústicos, exceto Fo, mostraram-se alterados em ambos os grupos, quando comparados aos controles. CONCLUSÕES: Alterações vocais perceptivas e acústicas, e lesões laríngeas foram registradas tanto nos pacientes com phmetria normal como alterada, sinalizando para a importância da historia clínica e dos achados videolaringoscópicos no diagnóstico das laringites ácidas.

Evaluation of laryngeal mask as an alternative to endotracheal intubation in cats anesthetized under spontaneous or controlled ventilation

Objective To compare the cardiorespiratory effects and incidence of gastroesophageal reflux with the use of a laryngeal mask airway (LMA) or endotracheal tube (ET) in anesthetized cats during spontaneous (SV) or controlled ventilation (CV).Study design Prospective randomized experimental trial.Animals Thirty-two adult crossbred cats, weighing 2.7 +/- 0.4 kg.Methods the cats were sedated with intramuscular (IM) methotrimeprazine (0.5 mg kg(-1)) and buprenorphine (0.005 mg kg(-1)), followed 30 minutes later by induction of anesthesia with intravenous (IV) thiopental (12.5-20 mg kg(-1)). An ET was used in 16 cats and an LMA in the remaining 16 animals. Anesthesia was maintained with 0.5 minimum alveolar concentration (0.6%) of halothane in oxygen using a Mapleson D breathing system. Cats in both groups were further divided into two equal groups (n = 8), undergoing either SV or CV. Neuromuscular blockade with pancuronium (0.06 mg kg(-1)) was used to facilitate CV. Heart and respiratory rates, direct arterial blood pressure, capnometry (PE'CO2) and arterial blood gases were measured. Gastric reflux and possible aspiration was investigated by intragastric administration of 5 mL of radiographic contrast immediately after induction of anesthesia. Cervical and thoracic radiographs were taken at the end of anesthesia. Data were analyzed using ANOVA followed by Student-Newman-Keuls, Kruskal-Wallis or Friedman test where appropriate.Results Values for PaCO2 and PE'CO2 were higher in spontaneously breathing cats with the LMA when compared with other groups. Values of PaO2 and hemoglobin oxygen saturation did not differ between groups. Gastroesophageal reflux occurred in four of eight and two of eight cats undergoing CV with ET or LMA, respectively. There was no tracheal or pulmonary aspiration in any cases.Conclusions and clinical relevance the use of an LMA may be used as an alternative to endotracheal intubation in anesthetized cats. Although aspiration was not observed, gastric reflux may occur in mechanically ventilated animals.

Eletromanometria do esfíncter superior do esôfago antes e após perfusão esofágica com ácido clorídrico 0,1N: estudo experimental no cão

Racional — A resposta do esfíncter esofágico superior ao refluxo gastroesofágico é controvertida. A perfusão esofágica com ácido clorídrico é modelo de estudo da ação do ácido o componente mais agressivo do refluxo sobre o esfíncter. Objetivos - Estudar o efeito da acidificação esofágica sobre o esfíncter esofágico superior através da eletromanometria esofágica. - Material e Métodos - em 30 cães adultos de ambos os sexos foram registrados estudos eletromanométricos do esôfago. A técnica utilizada foi a de puxada intermitente da sonda e perfusão contínua dos cateteres com água destilada. Estes exames permitiram as medidas da amplitude da pressão (mm Hg) e do comprimento (cm) do esfíncter superior do esôfago em condições basais (momento 1). Após esta fase, os animais foram submetidos a perfusão esofágica e divididos em 3 grupos de 10, na dependência da solução utilizada na perfusão e do momento do estudo: Grupo 1: perfusão esofágica com água destilada e estudos eletromanométricos realizados aos 15 minutos (momento 2) e 30 minutos (momento 3) do término da perfusão; Grupo 2: perfusão esofágica com HCl 0,1 N e estudos eletromanométricos realizados 15 minutos após o término da perfusão (momento 2); Grupo 3: perfusão esofágica com HCl 0,1 N e estudos eletromanométricos realizados 30 minutos após o término da perfusão (momento 3). Resultados/Conclusão - Os resultados observados permitiram concluir que a acidificação do esôfago não provocou alterações significativas sobre a amplitude de pressão e comprimento do esfíncter superior do esôfago.

Study on functional cardiorespiratory changes after laparoscopic Nissen fundoplication

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication.METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from 25 to 67 years, with a mean of 44.4 +/- 10.9. Pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (PRE) and in the first (PO1), second (PO2), fifth (PO5) and thirtieth (PO30) postoperative periods.RESULTS: Thirty-two patients were evaluated, of whom 59% were females. Mean age was 44.4 +/- 10.9 years. Lung volumes had significant decrease at PO1 and PO2 and were similar to PRE values at PO5. Respiratory pressures were altered only at PO1. The distance covered in the 6-minute walk test had significant reduction until PO2, and climbing time in the stair-climbing test significantly increased at PO2.CONCLUSION: Patients submitted to LNF surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.

Refluxo gastroesofágico: estudo comparativo da receptividade e sensibilidade entre seriografia e ultrassonografia

OBJETIVO: Estudo comparativo da receptividade (colaboração) e sensibilidade da seriografia do esôfago, estômago e duodeno em relação à ultrassonografia do esôfago intra-abdominal em pacientes com suspeita de refluxo gastroesofágico. MATERIAIS E MÉTODOS: Foram incluídos no estudo 42 pacientes pediátricos (26 masculinos, com idade média de 33,64 ± 34,33 meses, e 16 femininos, com idade média de 31,02 ± 35,56 meses) com suspeita de refluxo gastroesofágico, os quais foram submetidos, inicialmente, a seriografia do esôfago, estômago e duodeno, e posteriormente, a ultrassonografia do esôfago intra-abdominal. RESUL-TADOS: A análise estatística comparativa entre os sexos e as idades sugere não haver evidência de associação com a colaboração, tanto para a seriografia do esôfago, estômago e duodeno como para a ultrassonografia do esôfago intra-abdominal. Entretanto, na classificação quanto ao tipo de colaboração, a técnica de seriografia do esôfago, estômago e duodeno apresentou menos de 50% de colaboração, enquanto 80,49% dos pacientes colaboraram com a ultrassonografia do esôfago intra-abdominal. Quanto à sensibilidade do diagnóstico de refluxo gastroesofágico, a técnica de ultrassonografia do esôfago intra-abdominal (85,7%) foi significativamente superior à de seriografia do esôfago, estômago e duodeno (47,6%). CONCLUSÃO: O presente estudo sugere que se proceda a ultrassonografia do esôfago intra-abdominal, mesmo na ausência de refluxo gastroesofágico na seriografia do esôfago, estômago e duodeno.

Esophageal and gastric biopsies in symptomatic children and adolescents. Should both be performed?

This study investigated the relationship among the histological diagnosis of esophagitis and gastritis in children and adolescents with gastroesophageal reflux disease (GERD) and/or dyspepsia. Records of 366 patients submitted to endoscopic biopsies were reviewed. Two groups were analyzed: G1 n=258 with esophageal and gastric biopsies, G2 n=108 with gastric biopsies only. For total subjects median age (range) was 8.5y (2mo-19.9y). Helicobacter pylori infection was detected in 30.6 %, median age 12.5y for H pylori-infected and 5.5y for uninfected children. Histological esophagitis was found in 216/258 (83.7 %) and gastritis in 95/258 (36.8 %) of G1. Both biopsies were normal for 13.6 % cases. Normal gastric biopsies were associated with esophagitis in 128/ 163 (78.5 %) of G1, but gastritis was associated with normal esophageal biopsies in only 7/95 (7.4 %) (0<.001). Histological gastritis was found in 80/108 (74.1 %) of G2 patients. Therefore, for symptomatic children both biopsies are indicated.
