RESUMO

BACKGROUND: Oropharyngeal dysphagia (OD) is common among older adults. Some studies have evaluated the efficacy of a texture-modified diet on mortality but with short-term follow-up. We aimed to evaluate the effect of a texture-modified diet and controlled bolus volume on all-cause mortality after 12 months in older persons with OD. METHODS: This secondary analysis of a randomized clinical trial included patients aged ≥60 years with a diagnosis of OD. They were concurrently and randomly assigned to receive either a texture-modified food diet and controlled bolus volume (intervention group) or standard treatment (control group) with 12 months of follow-up. Secondary outcomes were oral intake, weight, handgrip strength, phase angle, and aspiration pneumonia. Kaplan-Meier analysis and the Cox proportional hazards model were used for mortality analysis. RESULTS: A total of 127 participants (intervention group: 64 and control group: 63) were recruited, with a mean age of 76 years. The probability of all-cause mortality was significantly lower in the intervention group (n = 8, 12%) than in the control group (n = 18, 29%) (hazard ratio = 0.36 [95% CI = 0.16-0.86]; P = 0.01). There were 5 (7.9%) and 10 (16.1%) aspiration pneumonia events in the intervention and control groups, respectively (not significant) in 12 months of follow-up. Changes were observed in protein consumption (P = 0.01), body weight (P = 0.04), body mass index (P = 0.004), handgrip strength (P = 0.02), and phase angle (P = 0.04) between the treatment groups. CONCLUSION: Compared with the standard treatment, the dietary intervention improved efficacy by limiting nutrition complications, aspiration pneumonia, and all-cause mortality.

RESUMO

The association between impairments in swallowing safety detected via fiberoptic endoscopic evaluation of swallowing (FEES) and dysphagia complications has been evaluated in small studies that have not allowed obtaining precise estimates of the presence of such an association. The objective of this study was to evaluate the risk of dysphagia complications associated with the detection of premature spillage, residue, penetration, and aspiration via FEES. A systematic review and meta-analysis of the literature were carried out. A search strategy was established using terms of controlled and free vocabulary (free text) in the PubMed, Lilacs, Embase, Medline, and Cochrane databases. The initial search in the databases identified 3545 articles, of which 321 were excluded due to duplication, 3224 were selected for review of titles and abstracts, 45 were selected for full-text review, 37 were excluded for not meeting the selection criteria, and 8 were included for the final analysis, with a total population of 1168 patients. Aspiration increased the risk of pneumonia (OR 2.97, 95% CI 1.52-5.80, P = 0.001). The number of studies that have evaluated the relationship of other FEES findings with dysphagia complications was limited (≤ 3). One study found a higher risk of mortality in patients with aspiration (OR 4.08, 95% CI 1.60-10.27, P = 0.003). Another study that evaluated the risk of mortality in a combined group of penetration and aspiration found no higher risk of mortality. Penetration, residue, and premature spillage were not found to be associated with an increased risk of pneumonia, mortality, or other outcomes. Aspiration demonstrated via FEES was associated with an increased risk of pneumonia and mortality. There is insufficient evidence for the capacity of premature spillage, penetration, and residue to predict dysphagia complications.

RESUMO

Background: Laryngeal paralysis is a disorder that affects the movement of the arytenoid cartilages, creating an obstacle to the passage of air during inspiration. The disease is progressive and clinical signs are associated with upper airway obstruction. Diagnosis occurs through observation of laryngeal movements, and it is important to rule out concomitant diseases. In severely affected animals, surgery is recommended to alleviate clinical signs and improve quality of life. The aim of this report is to report a case of idiopathic laryngeal paralysis in a dog submitted to arytenoid unilateralization to clear the upper airways and evaluate the effectiveness of the technique. Case: A 5-year-old male Great Dane dog was referred to the Hospital de Clínicas Veterinárias (HCV) of the Federal University of Rio Grande do Sul (UFRGS) with severe respiratory distress and respiratory stridor. The animal was taken directly to the emergency room, where it was promptly submitted to oxygen therapy with the aid of a mask, was medicated with nalbuphine hydrochloride 0.3 mg/kg intramuscularly and venous access was performed. After stabilization, complete blood count, biochemical profile, blood gas analysis and chest X-ray were requested. In the anamnesis, the tutor reported that the dog showed signs of fatigue with exercise intolerance, coughing similar to choking, breathing difficulties and noisy breathing, especially on hotter days and in situations of exertion, stress or euphoria. He mentioned that the signs were progressive, having started 2 months ago and that they were more frequent and lasting. The patient was diagnosed with laryngeal paralysis through transoral laryngoscopy and referred to surgery. The improvement in the breathing pattern and the absence of post-surgical complications resulted in the patient being discharged 6 days after hospitalization. Discussion: When the origin of laryngeal paralysis (LP) is undefined, the acquired form may be a consequence of generalized polyneuropathy, polymyopathy, neoplasia, endocrinopathy, iatrogenic or idiopathic injury. The patient under study did not present clinical signs or history of disease, therefore, the case was classified as idiopathic in origin. Laryngeal paralysis of unknown cause is the most common and affects mainly middle-aged to elderly males, large or giant breeds. The disease is often described in Labrador Retriever dogs, but it can affect other breeds such as Great Dane. This information corroborates the profile of the patient in this study. Although oral laryngoscopy is the recommended method for confirming the diagnosis in dogs with characteristic signs of LP, the diagnosis can also be obtained by transnasal laryngoscopy or echolaryngography, however, previous studies have shown that the sensitivity and specificity of diagnosis through echoaryngography is inferior to transnasal laryngoscopy, suggesting that direct visualization of the larynx is better to indirect visualization. Dogs with signs of moderate to severe respiratory distress or whose quality of life is affected as a result of LP are candidates for surgical treatment, as in this case, in which the patient had exercise intolerance and severe respiratory distress. The arytenoid unilateralization procedure proved to be effective in improving the quality of life of the patient under study, achieving excellent postoperative results and approval by the tutor. In this case, transoral laryngoscopy was essential to determine the diagnosis and establish the treatment. Although the goal of improving quality of life has been achieved without major complications, the animal must receive long-term follow-up due to a possible correlation with generalized polyneuropathy and long-term complications.

RESUMO

Early detection of dysphagia and specifically aspiration is essential to prevent and reduce complications of hospitalized patients in rehabilitation centers. Bedside screening test are often used to evaluate swallowing disorders, but their results may be questionable due to insufficient and inconsistent sensitivity and specificity. To compare the sensitivity and specificity of various bedside screening tests for detecting aspiration in hospitalized rehabilitation patients. A prospective observational study was performed in 150 consecutive patients of a tertiary rehabilitation hospital. Patients were evaluated regarding clinical predictors for aspiration, maximum phonation time (MPT), Eating Assessment Tool 10 (EAT-10) questionnaire, tongue strength and endurance (Iowa Oral Performance Instrument [IOPI]) and a swallowing test (Volume-Viscosity Swallow Test [V-VST]). Flexible Endoscopic Evaluation of Swallowing (FEES) was the reference test. Of the 144 patients included, 22% aspirated on FEES. Previous history of pneumonia, dysarthria, wet voice, and abnormal cough reflex were significantly associated with aspiration. The sensitivity, specificity and accuracy for V-VST (83.3%, 72.6%, 74.8%, respectively) and EAT-10 (82.8%, 57.7%, 62.8%, respectively) to detect aspiration were superior than those of other methods. Maximum tongue strength on IOPI and MPT presented high sensitivity but low specificity to detect aspiration. Clinical predictors of aspiration (previous history of pneumonia, dysarthria, wet voice, and abnormal cough reflex) associated with either V-VST or EAT-10 may be good screening methods to detect aspiration in patients hospitalized in a rehabilitation center.

RESUMO

La neumonía lipoidea es una enfermedad respiratoria poco conocida que resulta de la acumulación de lípidos de origen endógeno o exógeno a nivel del alveolo pulmonar. Suele ser subdiagnosticada ya que la presentación clínica es inespecífica, por lo que suele confundirse con otras patologías broncopulmonares. Se presentó el caso de un paciente de 18 años antecedentes de aspiración accidental de combustible que seis horas después comenzó con fiebre, hemoptisis, tos y disnea. Se realizó radiografía de tórax donde se observó una neumonía en base derecha que unido al interrogatorio y a la realización de la broncoscopía confirmaron el diagnóstico de neumonía lipoidea. El paciente evolucionó favorablemente con el tratamiento(AU)

Lipoid pneumonia is a little known respiratory disease that results from the accumulation of lipids of endogenous or exogenous origin in the pulmonary alveolus. It is usually underdiagnosed since the clinical presentation is nonspecific, which is why it is often confused with other bronchopulmonary pathologies. We report the case of an 18-year-old patient with a history of accidental fuel aspiration, who ran fever six hours later, together with hemoptysis, cough, and dyspnea. Chest X-rays showed a right base pneumonia. The questioning and the performance of the bronchoscopy confirmed the diagnosis of lipoid pneumonia. The patient evolved favorably with the treatment(AU)

RESUMO

RESUMEN: ¿Por qué es importante la salud oral en la prevención de enfermedades respiratorias en tiempos de pandemia? La razón es simple, cualquier enfermedad respiratoria en la persona mayor, podría eventualmente activar alarma de COVID-19 positivo, pudiendo ser esta ocasionada por otro motivo, sin mencionar el riesgo aumentado de tener una enfermedad previa de tipo respiratoria en tiempos de pandemia, sobre todo, en una población de riesgo como las personas mayores institucionalizadas. Por esta razón, la prevención en higiene oral de personas mayores mediante un Protocolo que proponga lineamientos a seguir en Establecimientos de Larga Estadía para Adultos Mayores, es fundamental en la prevención de Neumonía por aspiración. Cabe mencionar, que desde antes de surgir el COVID-19, ya la Neumonía se considera la principal causa de muerte por enfermedades infecciosas en la población chilena, y la primera causa específica de muerte en los mayores de 80 años.

ABSTRACT: Why is oral health important in the prevention of respiratory diseases in times of pandemic? The reason is simple, any respiratory disease in the elderly could eventually trigger a positive COVID-19 alarm, and this could be caused by another reason, not to mention the increased risk of having a previous respiratory-type illness in times of pandemic, over everything, in a population of risk like the institutionalized older people. For this reason, the prevention of oral hygiene in older people through a Protocol that proposes guidelines to be followed in long-stay establishments for older adults, is essential in the prevention of aspiration Pneumonia. It is worth mentioning that, before the emergence of COVID-19, Pneumonia was considered the main cause of death from infectious diseases in the Chilean population and the first specific cause of death in those over 80 years of age.

RESUMO

ABSTRACT Purpose: to identify associated factors and preventive measures for aspiration pneumonia in hospitalized elderly patients. Methods: the PPOT (population, predictor, outcome, and type of study) was the strategy used to define the eligibility criteria: (1) Population: people over 60 years of age; (2) predictor: hospitalized patients (3) Outcomes: associated factors and measures to prevent aspiration pneumonia; (4) Type of study: Observational Studies (transversal and case-control). We performed the data collection in the PubMed, Lilacs, Scielo, Google Scholar, Science Direct, and Web of Science databases. Observational studies on factors associated with aspiration pneumonia and preventive measures in the elderly, without language restriction and available in full, were included. Data on authors/year/country, objective, methodology, sample, and results, were collected. The risk of bias was assessed, according to the JBI Critical Appraisal Checklist. Results: a case-control and two cross-sectional studies were analyzed. One paper presented a smaller sample with 86 patients, and another presented a larger sample comprising 443 patients. The median age was 77 years old. Conclusion: factors such as severe stroke, dysphagia, advanced age, male gender, coronary heart disease, lower Glasgow coma scale score, use of mechanical ventilation for more than 48 hours, and aspiration of colonized gastric juice were associated with aspiration pneumonia.

RESUMO

Abstract Background and objectives: Pregnant women are considered patients at risk for pulmonary aspiration of gastric contents. The study aim was to evaluate the gastric antral cross-sectional area using ultrasound. Method: In this prospective study, 85 scheduled term pregnant women underwent gastric ultrasound. The outcomes were the measurement of the gastric antral cross-sectional area (main outcome), the estimated gastric volume, the incidence of pregnant women at risk for pulmonary aspiration, and the association between gastric antral cross-sectional area and clinical-demographic characteristics. Gastric antral cross-sectional area and gastric volume were compared according to body mass index <30 or ≥30. Results: The median (IIQ) for gastric antral cross-sectional area was 4 cm2 (2.8-6.3), for the estimated gastric volume it was 49.8 mL (33.7-87.2), and for the gastric volume estimated in mL.kg-1 it was 0.62 mL.kg-1 (0.39-0.95). The 95th percentile [95% confidence interval (CI)] of the gastric antral cross-sectional area and the estimated gastric volume were ≤10.3 cm2 (95% CI: 7.6-15.6) and 1.42 mL.kg-1 (95% CI: 1.20-2.64), respectively. The incidence of pregnant women at risk for pulmonary aspiration was 3.5% (CI: 3.5 (1.2-9.8)). There was a positive correlation between gastric antral cross-sectional area and weight, p < 0.001 and body mass index <0.001. Patients with a body mass index ≥30 had a gastric antral cross-sectional area and an estimated gastric volume greater than those with a body mass index <30, respectively, p < 0.01 and p < 0.02. Conclusion: Measuring the gastric antral cross-sectional area of pregnant women is feasible and easy. There was positive correlation between gastric antral cross-sectional area, body weight and body mass index. The estimation of gastric volume by measuring the gastric antral cross-sectional area can identify patients at risk for pulmonary aspiration. Obese patients had a gastric antral cross-sectional area and an estimated gastric volume greater than non-obese patients.

RESUMO

OBJECTIVES: To evaluate the sensitivity and specificity of the modified Evans blue dye test compared to the fibre-optic endoscopic evaluation of swallowing to detect aspiration in tracheostomised patients. METHODS: This observational accuracy study included 17 patients hospitalised for respiratory complications, subjected to prolonged intubation, and for this reason, tracheostomised. RESULTS: Mean patient age was 60.2 ± 21.0 years. Aspiration was identified in 10 patients when assessed by fibre-optic endoscopic evaluation of swallowing; of these, 1 had aspiration when evaluated by modified Evans blue dye test. The dye test had a sensitivity of 10.0 per cent and specificity of 100.0 per cent for detecting aspiration. Fibre-optic endoscopic evaluation of swallowing revealed no statistically significant associations between aspiration presence and: speech and language therapy duration, intubation time, or tracheostomy plus mechanical ventilation duration. CONCLUSION: The modified Evans blue dye test is simple and inexpensive, and does not require prior knowledge in endoscopy; it may be used as an initial screening test in all tracheostomised patients for evaluating aspiration. However, fibre-optic endoscopic evaluation of swallowing should be used for a more comprehensive diagnosis of tracheostomy patients, especially for those at high risk for aspiration.

RESUMO

Introdução: Pacientes hospitalizados em Unidade de Terapia Intensiva (UTI) geralmente mostram má higiene bucal, o que contribui significativamente para o agravamento da contaminação local, com a presença de patógenos respiratórios potenciais. Objetivo: Caracterizar qualitativamente o perfil da microbiota bucal durante permanência na UTI, além da identificação de alterações bucais e salivares. Materiais e métodos: Foi realizado um estudo prospectivo em pacientes internados na UTI de um hospital oncológico, os quais foram avaliados clínica e microbiologicamente após 24 (T1), 72 (T2) e 120 (T3) horas consecutivas à admissão na UTI. Foram identificados os principais patógenos em cada momento e o perfil da microbiota oral foi comparado. Resultados: A amostra final foi de 30 pacientes, 23 homens e 7 mulheres, com idade média de 61 anos. Em T1, 96,67% dos pacientes apresentaram crescimento de microorganismos patogênicos, sendo identificados 14 tipos diferentes. Em T2 18 tipos de patógenos diferentes e em T3, 21 tipos, dos quais os mais prevalentes nas três coletas foram Staphylococcus não produtor de coagulase e Candida albicans. Clinicamente foram observados presença e progressão do biofilme visível (61%), cálculo (36,89%), condição periodontal deficiente (33,11%). Em relação à condição salivar verificou-se saburra lingual (92,11%), ressecamento labial (86,67%), hipossalivação (36,67%), assialia (52%) e escoamento salivar (8,89%). Conclusão: O biofilme do dorso de língua de pacientes em UTI pode representar um nicho considerável de patógenos respiratórios potenciais, uma vez que microorganismos etiológicos relacionados à pneumonia nosocomial foram isolados já no primeiro dia de internação, com a colonização subsequente por uma variedade de microorganismos predominantemente gram-negativos(AU)

Introduction: Hospitalized patients receiving treatment at Intensive Care Units (ICU) usually show poor oral hygiene, and may have the mouth and oropharingeal region colonized by pathogens involved in nosocomial pneumonia. The presence of these pathogens may increase the risk for respiratory diseases. OBJECTIVES: The aim of this study was to qualitatively characterize the oral microbiota profile of critical patients during ICU stay, besides the identification of oral and salivary alterations. Materials and Methods: A prospective study was carried out on patients admitted to the ICU from a cancer hospital, who were evaluated clinically and microbiologically (tongue-to-mouth swabs) after 24h (T1), 72h (T2) and within 120 consecutive hours (T3) after ICU admission to the ICU. The main pathogens were identified at each moment and the oral microbiota profile was compared. In addition, the major oral and salivary changes were identified. Results: The final sample consisted of 30 patients, 23 men and 7 women, with a mean age of 61 years. The reasons for hospitalization were 30% postoperative of oncological surgeries and 70% of medical emergencies. In T1, 96.67% of the patients presented growth of pathogenic microorganisms, being identified 14 different types. In T2, 18 different pathogen types were identified, and in T3, 21 pathogens, of which the most prevalent Coagulase negative staphylococcus and Candida albicans were the most prevalent in the three collections. It was observed the presence and progression of visible biofilm (61%), calculus (36.89%), poor periodontal condition (33.11%), partial teeth presence (26.67%), total edentulism (23.33%), cavities (10%), presence of residual root (20%). In relation to the salivary condition, there was accumulation of lingual (92.11%), labial dryness (86.67%), hyposalivation (36.67%), asialia (52%) and salivary flow (8.89%). Conclusion: The tongue dorsum biofilm of ICU patients may represent a considerable niche of potential respiratory pathogens, since etiological microorganisms related to nosocomial pneumonia were isolated on the first day of hospitalization, with subsequent colonization by a variety of microorganisms predominantly gram-negatives. The introduction of professional care directed to oral health and biofilm control in this group of patients could represent a significant contribution to the reduction of diseases to the health of the patient in the ICU(AU)

Introducción: Pacientes hospitalizados en UTI generalmente muestran mala higiene bucal, lo que contribuye significativamente al agravamiento de la contaminación local, con la presencia de patógenos respiratorios potenciales. Objetivo: Caracterizar cualitativamente el perfil de la microbiota bucal durante permanencia en la UTI, además de la identificación de alteraciones bucales y salivares. Materiales y métodos: Se realizó un estudio prospectivo en pacientes internados en la UTI de un hospital oncológico, los cuales fueron evaluados clínica y microbiológicamente después de 24 (T1), 72 (T2) y 120 (T3) horas consecutivas a la admisión en la UTI. Se identificaron los principales patógenos en cada momento y el perfil de la microbiota oral fue comparado. Resultados: La muestra final fue de 30 pacientes, 23 hombres y 7 mujeres, con edad media de 61 años. En T1, el 96,67% de los pacientes presentaron crecimiento de microorganismos patógenos, siendo identificados 14 tipos diferentes. En T2 18 tipos de patógenos diferentes y en T3, 21 tipos, de los cuales los más prevalentes en las tres colectas fueron Staphylococcus no productor de coagulasa y Candida albicans. Se observó la presencia y progresión del biofilme visible (61%), cálculo (36,89%), condición periodontal deficiente (33,11%). En cuanto a la condición salivar se verificó saburra lingual (92,11%), resecamiento labial (86,67%), hiposalivación (36,67%), asialia (52%) y flujo salivar (8,89%). Conclusión: El biofilm del dorso de lengua de pacientes en UTI puede representar un nicho considerable de patógenos respiratorios potenciales, ya que microorganismos etiológicos relacionados a la neumonía nosocomial se aislaron ya en el primer día de internación, con la colonización subsecuente por una variedad de microorganismos predominantemente gram-negativa(AU)

RESUMO

RESUMEN Las hendiduras laríngeas posteriores son anomalías congénitas de la laringe de baja incidencia que comprometen la región interaritenoidea o la lámina cricoidea. En caso de extenderse hasta la tráquea son denominados clefts laringo-tráqueo-esofágicos. Su clínica es inespecífica y debe sospecharse en todo niño con trastorno de deglución y neumonía aspirativa a repetición. A continuación, presentamos un caso de un cleft laríngeo tipo 2 tratado endoscópicamente.

ABSTRACT The posterior laryngeal clefts are congenital anomalies of the larynx of low incidence that comprise the interaritenoid region or the cricoid lamina. In case of extending to the trachea they are called laryngo-tracheo-esophagic clefts. Its clinic is non-specific and should be suspected in any child with swallowing disorder and aspiration pneumonia. We present a case of an endoscopically treated laryngeal cleft type 2.

RESUMO

Aspiration pulmonary disease is the condition in which there is a passage of gastric or oral content to the airways; the extent of aspiration is conditioned by the amount and frequency with which it occurs. The diagnostic approach of this pathology begins with an adequate clinical history with special emphasis on pathologies that generate poor swallowing mechanics such as neurological diseases, esophageal atresia and patients with a history of gastroesophageal reflux. The studies used for the diagnosis of this syndrome are chest X-ray, swallowing mechanics evaluation with barium, Ph-metry, scintigraphy with Tc99 for gastroesophageal reflux, delayed pulmonary scanning, endoscopic study of the digestive tract and bronchoscopy in search of lesions in the respiratory mucosa and bronchial lavage to detect lipid-laden alveolar macrophages which have been linked to the presence of aspiration syndromes in several publications

La neumopatía por aspiración es la condición en la que existe un paso de contenido gástrico a la vía aérea. La magnitud de la aspiración depende de la cantidad y la frecuencia con la que se presenta. El abordaje diagnóstico de esta patología se inicia con una historia clínica adecuada con especial énfasis en patologías que generen una mala mecánica de deglución como pueden ser enfermedades neurológicas, atresia esofágica y pacientes con antecedentes de reflujo gastroesofágico. Los estudios que se requieren para el diagnóstico de esta enfermedad constan de radiografía de tórax, estudio de deglución, Ph-metria, gamagrama para reflujo, estudio endoscópico de vía digestiva y broncoscopia en búsqueda de lesiones en la mucosa respiratoria y realización de lavado bronquial para macrófagos alveolares cargados de lípidos

RESUMO

La aspiración de hidrocarburos puede causar un daño significativo a los pulmones al inducir una respuesta inflamatoria, alveolitis exudativa hemorrágica y pérdida de la función del tensioactivo pulmonar. El efecto secundario más grave de la aspiración de hidrocarburos es la neumonía por aspiración. Anteriormente se han notificado casos de neumotórax, neumatocele, síndrome de dificultad respiratoria aguda (SDRA), absceso pulmonar, fístula broncopleural, derrame pleural bilateral hemorrágico y pioneumotórax. En este artículo presentamos el caso de un paciente hospitalizado debido a neumonía por aspiración que desarrolló pleuritis y neumotórax después de ingerir disolvente para pintura. Se presenta este caso ya que raramente se ha informado en niños como causa de complicaciones pulmonares diferentes. Es necesario evaluar integralmente a los pacientes con complicaciones asociadas a la intoxicación por hidrocarburos. Debe evitarse el alta hospitalaria temprana de los pacientes, quienes deben ser controlados durante, al menos, 48 horas, aunque no tengan síntomas respiratorios. Debe considerarse que los pacientes con neumonía química pueden tener complicaciones pulmonares graves.

Hydrocarbon aspiration (HA) can cause significant lung disease by inducing an inflammatory response, hemorrhagic exudative alveolitis, and loss of surfactant function. The most serious side effect of HA is aspiration pneumonia. Pneumothorax, pneumatocele, acute respiratory distress syndrome (ARDS), pulmonary abscess, bronchopleural fistula, bilateral hemorrhagic pleural effusion and pyopneumothorax were previously reported. Hereby we report a patient hospitalized due to aspiration pneumonia who developed pleurisy and pneumothorax after drinking paint thinner. It is presented as it was seldom reported in children to cause distinct pulmonary complications. Patients with complaints associated withhydrocarbon poisoning must be fully evaluated. They must not be discharged from the hospital early and must be followed for at least 48 hours even if they don't have respiratory symptoms. It should be kept in mind that severe pulmonary complications can develop in patients with chemical pneumonia.

RESUMO

Abstract Introduction Dysphagia is a common symptom in children with cerebral palsy, either in oral or pharyngeal phases. Children who face such difficulties tend to show health problems such as food aspiration, malnutrition and respiratory infections. Videofluoroscopic swallowing study is the most recommended for these cases, as it reveals the real situation during swallowing. Objective The study aimed to verify the occurrence of aspiration pneumonia in children with cerebral palsy after videofluoroscopy. Methods The population for this prospective cross-sectional study involved 103 children with cerebral palsy, referred for videofluoroscopic who had returned for medical examination after a week to search for signs and symptoms of pneumonia. Results The study involved 46 girls (44.66%) and 57 boys (55.34%), aged between 0 and 14 years of age. Of the total, 84 (81.5%) had dysphagia, of which 24 (23.3%) were severe, 8 (7.7%) were moderate and 52 (50.4%) were mild dysphagia. None of the children presented aspiration pneumonia or infectious complications during the course of videofluoroscopy or after the procedure. Conclusion In the population studied, the authors found no cases of aspiration pneumonia, even with tracheal aspiration present in 32 (31.07%) cases.

RESUMO

The objective of this study was to systematically review the available literature, evaluating if periodontal disease is a risk factor for the development of aspiration pneumonia. The data sources were publications available between 01/01/1980 and 01/15/2011, on the following databases: MEDLINE, LILACS, Evidence Portal, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Academics. Inclusion criteria included randomized clinical trials, case-control and cohort studies, as well as cross sectional studies, in Portuguese and English. Teams of reviewers, independently and in duplicate, screened titles and abstracts of full text articles to determine eligibility. The selected articles were read in full and the variables evaluated independently and described in predetermined forms according to clinical outcomes. As a result, five studies out of 653 publications were included: three case-control studies and two cohort studies. Although these studies indicate a positive association between the presence of periodontal disease and the occurrence of aspiration pneumonia, the results must be interpreted with caution. They should not be taken as definitive conclusions due to variations in methodology and limitations, such as sample size, inadequate control of potential confounding variables, lack of calibration of periodontal measurements and inconsistent criteria for the establishment of aspiration pneumonia. There is little evidence to affirm that periodontal disease is a risk condition factor for aspiration pneumonia. Future studies are necessary to elucidate this association, as well as to establish the potential benefit of periodontal treatment with the goal of reducing the risk of developing aspiration pneumonia.

O Objetivo do estudo foi revisar sistematicamente a literatura disponível, avaliar se a doença periodontal é um fator de risco para o desenvolvimento de pneumonia por aspiração. As fontes de dados foram publicações disponíveis entre 01/01/1980 e 15/01/2011, nas seguintes bases de dados: Medline, Lilacs, Evidence Portal, Cochrane Central Register de Ensaios Controlados (CENTRAL) e Google Academics. Os estudos de seleção foram ensaios clínicos randomizados, estudos de caso-controle e coorte, assim como estudos transversais, em Português e Inglês. Equipes de revisores, independente e em duplicado fez os títulos de telas e resumos e do texto completo para determinar a elegibilidade. Os artigos selecionados foram lidos na íntegra e as variáveis avaliadas de forma independente e descrito em formas pré-determinadas de acordo com os resultados clínicos. Como resultado, cinco estudos de 653 publicações foram incluídos: três estudos de caso-controle, um estudo de coorte e um estudo prospectivo, com análise retrospectiva de dados. Embora esses estudos indicam uma associação positiva entre a presença de doença periodontal e a ocorrência de pneumonia aspirativa, os resultados devem ser interpretados com cautela. Eles não devem ser tomados como conclusões definitivas devido a variações nas metodologias e limitações, tais como tamanho da amostra, controle inadequado de potenciais variáveis de confusão, a falta de calibração das medições periodontais e sem critérios consistentes para o estabelecimento de pneumonia por aspiração. Há pouca evidência para afirmar que a doença periodontal é um fator condição de risco para pneumonia aspirativa. Futuros estudos são necessários para elucidar essa associação, bem como para estabelecer o potencial benefício do tratamento periodontal com o objetivo de reduzir o risco de desenvolver pneumonia por aspiração.
