RESUMEN
Pseudoacalasia se manifesta de forma semelhante à acalasia do esfíncter esofágico inferior (EEI). Corresponde a 2,4 a 4% dos casos que simulam acalasia 1 . Estima-se que cerca de 50% dos casos de pseudoacalasia correspondam a malignidade primária do esôfago e da junção gastroesofágica e 18% a malignidades secundárias como doença metastática 1,2 . Etiologias benignas também estão descritas. No presente trabalho apresentamos um caso de pseudoacalasia com ênfase nos aspectos radiológicos. Revisamos também aspectos clínicos e radiológicos que podem auxiliar no diagnóstico diferencial entre acalasia e pseudoacalasia. (AU)
Pseudoachalasia is a condition that mimics idiopathic achalasia of the lower esophageal sphincter. It accounts for 2.4 to 4% of patients presenting with achalasia-like symptoms. It is estimated that about 50% of cases of pseudoachalasia correspond to primary malignancies of the esophagus and the esophagogastric junction and 18% to secondary malignancies such as metastases 1,2 . Benign causes are also described. In this report we emphasize radiological findings of a case of pseudoachalasia. We also review clinical and radiological aspects that might be auxiliary in the differential diagnosis between achalasia and pseudoachalasia. (AU)

Introdução: Realizar as medidas radiográficas do comprimento da face de amostra de crianças brasileiras do nascimento até um ano de vida para determinação de parâmetros radiográficos de normalidade. Materiais e Métodos: Foi realizada análise retrospectiva de radiografias simples de crânio para mensuração da face de crianças de até 12 meses em um hospital do sul do Brasil. Os exames foram realizados entre os anos de 2013 e 2018. Foram incluídas no estudo 170 radiografias cranianas de 85 crianças menores de um ano. Definidos parâmetros de mensuração, executados por três avaliadores e posteriormente comparados utilizando-se o coeficiente de correlação intraclasse e o teste ANOVA. Resultados: O coeficiente de correlação intraclasse foi alto, demonstrando a concordância dos examinadores e a reprodutibilidade das mensurações. Houve pequeno desvio padrão entre as medidas obtidas dos diferentes períodos etários. No geral, ocorreu crescimento da face estatisticamente significativo do primeiro ao terceiro trimestre. O crescimento foi menor e sem diferença estatisticamente significativa do terceiro para o quarto trimestre. Conclusão: Observou-se um aumento progressivo das dimensões dos ossos da face com o crescimento no primeiro ano de vida, especialmente nos primeiros 9 meses. A obtenção destes dados pode auxiliar na avaliação da normalidade para este período etário. (AU)
Introduction: To perform face length measurements on radiographs of Brazilian children from birth to one year of age in order to determine radiographic parameters of normality. Materials and Methods: We performed a retrospective analysis of simple skull radiographs for face measurement of children up to 12 months of age taken in a southern Brazilian hospital between 2013 and 2018. In total, 170 skull radiographs of 85 children under one year of age were included in the study. Measurement parameters were defined, then performed by three evaluators, and later compared using intraclass correlation coefficient and analysis of variance. Results: The intraclass correlation coefficient was high, demonstrating interexaminer agreement and reproducibility of the measurements. There was a small standard deviation between the measurements obtained from the different age groups. In general, there was a statistically significant growth of the face from the first to the third trimester. The growth was smaller and with no statistically significant difference from the third to the fourth trimester. Conclusion: We observed a progressive increase in the dimensions of the facial bones with growth in the first year of life, especially in the first 9 months. Obtaining these data will assist in the assessment of normality for this age group. (AU)

We report a case of Plummer-Vinson syndrome (PVS) and lower esophageal ring with a small sliding hiatal hernia. PVS is a rare entity formed by the combination of dysphagia, cervical esophageal web and iron deficiency anemia. It occurs mainly in middle-aged women1,2,3. A lower esophageal ring and a small sliding hiatal hernia were also observed in this case. We documented clinical manifestations of iron deficiency anemia through images and esophageal abnormalities through barium esophagogram. (AU)

The purpose of this article is to review the most frequent conditions associated with esophageal strictures on esophagogram. The most common causes include caustic ingestion, radiation therapy, malignancy, extrinsic compression, gastroesophageal reflux disease, infectious esophagitis, systemic diseases and membranes and rings. Adequate characterization of the stricture is necessary for formulation of the best diagnostic hypothesis and can be used to distinguish between malignant and non-malignant conditions. (AU)

PURPOSE: Verify whether voice modification after swallowing is associated with videofluoroscopic examination data. METHODS: 27 patients with oropharyngeal dysphagia underwent recording of sustained phonation of vowel /a/ before and after swallowing during videofluoroscopy. The GRBAS scale and the wet voice parameter were used to evaluate the data. Videofluoroscopy results showed stasis of food in the valleculae and piriform recesses, laryngeal penetration, tracheal aspiration, and degree of dysphagia. RESULTS: Decreased dysphonia grade and asthenia and increased strain were observed after swallowing, with no difference for the wet voice parameter. Sensitivity and specificity of ± 50% were observed for food stasis in the valleculae and piriform recesses. Sensitivity values of 80 and 66-75% were observed for detection of laryngeal penetration and tracheal aspiration and modification of vocal strain, respectively. Negative predictive values of 77-91% were found for the three assessment parameters with no correlation with the degree of oropharyngeal dysphagia. CONCLUSION: Modification of the GRBAS scale parameters after swallowing showed good compatibility with videofluoroscopy findings.
OBJETIVO: Verificar se a modificação da voz após a deglutição relaciona-se com os dados do exame de videofluoroscopia. MÉTODO: 27 indivíduos com disfagia orofaríngea realizaram a gravação da vogal sustentada /a/ antes e após a deglutição durante exame de videofluoroscopia. Utilizou-se a escala GRBAS e acrescentou-se o aspecto voz molhada para avaliação dos dados. Em relação ao exame, verificou-se estase de alimento em valéculas e recessos piriformes, penetração laríngea, aspiração traqueal e grau de disfagia. RESULTADOS: Houve diminuição do grau de alteração e astenia e aumento da tensão fonatória após a deglutição, sem diferença para o parâmetro voz molhada. Obteve-se sensibilidade e especificidade de ±50% para estase em recessos piriformes e valéculas; porém, sensibilidade de 80% para detecção de penetração e de 66-75% para aspiração e modificação da tensão fonatória, com 77-91% de valores preditivos negativos para os três parâmetros de avaliação, sem correlação com o grau de disfagia. CONCLUSÃO: A modificação dos parâmetros da escala GRBAS após a deglutição apresentou boa compatibilidade com achados da videofluoroscopia.

OBJECTIVE: To investigate the accuracy of clinical evaluation of swallowing in a sample of children with laryngomalacia or glossoptosis and describe the prevalence of dysphagia in each of these diseases, as well as characterize the swallow response to speech and language therapy interventions. STUDY DESIGN: Children aged 1 month to 11 years receiving care at the Department of Otolaryngology, Hospital de Clínicas de Porto Alegre, Brazil, were evaluated in a cross-sectional design. Evaluation of swallowing was performed at two time points by two blinded speech-language pathologists, one responsible for clinical evaluation and the other for videofluoroscopic study. The protocols employed were based on the instruments proposed by DeMatteo et al. (DeMatteo C, Matovich D, Hjartarson A. Comparison of clinical and videofluoroscopic evaluation of children with feeding and swallowing difficulties. Dev Med Child Neurol 2005;47:149-157.). RESULTS: The study sample consisted of 29 patients: 10 patients with laryngomalacia and 19 patients with glossoptosis. The sensitivity of clinical evaluation did not exceed 50% in any of the evaluations, but specificity reached 100% in some cases, using thickened liquids. The prevalence of dysphagia was 100%, and the use of thickened liquids significantly reduced tracheal aspiration. CONCLUSIONS: Dysphagia was highly prevalent in this sample. The sensitivity of clinical evaluation to detect laryngeal penetration and tracheal aspiration was low, as the majority of aspiration events were silent. The videofluoroscopic study is important in order to determine a safest method to feed the patient. Pediatr Pulmonol. 2017;52:41-47. © 2016 Wiley Periodicals, Inc.

Introduction Voice modification after swallowing may indicate changes in the transit of the bolus. Objective The aim of this study is to verify the use of perceptual voice analysis to detect oropharyngeal dysphagia. Study Design Case series. Methods Twenty-seven patients with dysphagia as diagnosed by videofluoroscopy and 25 without were evaluated. The sustained vowel /a/ was recorded before this exam and after swallowing different consistencies (pasty, liquid and solid). For the voice evaluation, the GRBAS scale (grade, roughness, breathiness, asthenia and strain) and the parameter "wet voice" were used. Three judges blinded to study group and time of emission performed voice analysis. Results Individuals with dysphagia showed significant decrease in grade of voice and asthenia and increase in strain after swallowing pasty substances, differing from individuals without dysphagia who showed no modification of the parameters after swallowing. The wet voice parameter showed no difference after swallowing in both study groups. Conclusion The decrease in grade and asthenia and increased strain are indicative of a swallowing disorder, indicating increased vocal strain to clean the vocal tract of food. The modification of vocal production after swallowing proved to be a trusted resource for detection of swallowing disorders.

CONTEXT: Videofluoroscopic swallowing study is a dynamic exam and allows the evaluation of the complete swallowing process. However, most published studies have only reported alterations in the oropharynx and pharyngoesophageal transition, leaving the analysis of the esophagus as a secondary goal. OBJECTIVES: The goal of this study was to investigate the prevalence of alterations in the esophageal phase thorough videofluoroscopic swallowing study in patients with dysphagia. METHODS: Consecutive patients with dysphagia who underwent videofluoroscopic swallowing study including esophageal analysis between May 2010 and May 2012 had their exams retrospectively reviewed. Patients were classified into two groups: Group I - without a pre-established etiological diagnosis and Group II - with neurological disease. During the exam, the patients ingested three different consistencies of food (liquid, pasty and solid) contrasted with barium sulfate and 19 items were analyzed according to a protocol. The esophageal phase was considered abnormal when one of the evaluated items was compromised. RESULTS: Three hundred and thirty-three (n = 333) consecutive patients were studied - 213 (64%) in Group I and 120 (36%) in Group II. Esophageal alterations were found in 104 (31%) patients, with a higher prevalence in Group I (36.2%), especially on the items esophageal clearance (16.9%) and tertiary contractions (16.4%). It was observed that 12% of individuals in Group I only presented alterations on the esophageal phase. CONCLUSION: Evaluation of the esophageal phase of swallowing during videofluoroscopic swallowing study detects abnormalities in patients with cervical dysphagia, especially in the group without pre-established etiological diagnosis.

Contexto A videofluoroscopia da deglutição é um exame dinâmico e permite a avaliação de todo o processo da deglutição, entretanto, a maioria dos estudos publicados relata apenas alterações na orofaringe e transição faringoesofágica, não considerando como importante as alterações esofágicas. Objetivos O objetivo da presente pesquisa foi verificar a prevalência de alterações na fase esofágica à videofluoroscopia da deglutição em pacientes com disfagia. Métodos Pacientes com queixa de disfagia submetidos à videofluoroscopia da deglutição incluindo estudo esofágico entre maio de 2010 e maio de 2012 tiveram seus exames revisados retrospectivamente. Os pacientes foram classificados em dois grupos: Grupo I - sem diagnóstico etiológico pré-estabelecido e Grupo II - com diagnóstico de doença neurológica. Durante o exame os pacientes ingeriram três consistências de alimento (líquido, pastoso e sólido) contrastadas com sulfato de bário e 19 itens foram analisados segundo protocolo. A fase esofágica foi considerada alterada quando um dos itens avaliados estivesse comprometido. Resultados Trezentos e trinta e três (n = 333) pacientes consecutivos foram estudados com 213 (64%) no Grupo I e 120 (36%) no Grupo II. Alterações esofágicas foram identificadas em 104 (31%) pacientes, sendo a prevalência maior no Grupo I (36,2%), principalmente, nos itens clareamento esofágico (16,9%) e contrações terciárias (16,4%). Pudemos observar que 12% dos indivíduos do Grupo I apresentaram somente alteração em fase esofágica.

RESUMEN
CONTEXT: Upper gastrointestinal bleeding associated to esophageal varices is the most dramatic complication of cirrhosis. It is recommended screening every cirrhotic for esophageal varices with endoscopy. OBJECTIVES: To evaluate the capacity of the platelet count/spleen diameter ratio in non-invasively predicting esophageal varices in a population of cirrhotics originated in an independent center from the one in which it was developed. METHODS: The study included patients from the ambulatory care clinic of cirrhosis of a Brazilian hospital and studied platelet count, spleen diameter and presence of esophageal varices, as well as Child and MELD scores. It used a cutoff value of 909 for the platelet count/spleen diameter ratio, as previously published. A sample of 139 patients was needed to grant results a 95% confidence level. RESULTS: The study included 164 cirrhotics, 56.7% male, with a mean age of 56.6 ± 11.6 years. In the univariate analysis, platelet count, spleen diameter, presence of ascites, Child and MELD scores and the platelet count/spleen diameter ratio were related to esophageal varices (P<0.05). The platelet count/spleen diameter ratio had sensitivity of 77.5% (95% CI = 0.700-0.850), specificity of 45.5% (95% CI = 0.307-0.602), positive predictive value of 79.5% (95% CI = 0.722-0.868), negative predictive value of 42.6% (95% CI = 0.284-0.567) and accuracy of 68.9% (95% CI = 0.618-0.760). In the multivariate analysis, platelet count was the only variable which related to esophageal varices (P<0.05). CONCLUSION: Platelet count/ spleen diameter ratio is not adequate to predict esophageal varices in cirrhotics.
