ABSTRACT
Introduction: Celiac disease is an autoimmune disease related to gluten that affects the small intestine. Dyspepsia is a set of symptoms of the upper abdomen that includes epigastric burning, postprandial fullness and early satiety and has a prevalence of 10-45% of the population with different etiological possibilities, including celiac disease. Objectives: To evaluate the prevalence of celiac disease in patients with a clinical diagnosis of dyspeptic syndrome and to study the sample regarding epidemiology, symptoms, endoscopic, histological and serological findings. Method: Observational research, based on a review of medical records of patients treated for uninvestigated dyspepsia. Patients over 18 years of age, with this dyspepsia and who had endoscopy, total immunoglobulin A and IgA antitransglutaminase were included. Those with diarrhea, constipation, malabsorption, refractory lactose intolerance or who presented extraintestinal signs or symptoms suggestive of celiac disease were excluded. Results: The initial sample was 1802 records and the final 200 patients. Of these, 100 had endoscopy, histology and antibody measurement, and the remaining 100 had endoscopy and antibody measurement, but not histology. Considering the total sample, the average age was 45.13 years and the female sex was predominant. Symptoms associated with gluten were reported in 6%. The antitransglutaminase antibody was positive in 1.5%. Considering the sample of 100 patients, the diagnosis of celiac disease had a prevalence of 3%. Conclusion: The prevalence of celiac disease in patients with a clinical diagnosis of dyspeptic syndrome was 3%.
Introdução: A doença celíaca é doença autoimune relacionada ao glúten que acomete o intestino delgado. A dispepsia é um conjunto de sintomas do abdome superior que inclui queimação epigástrica, plenitude pós-prandial e saciedade precoce e apresenta prevalência de 10-45% da população cursando com diversas possibilidades etiológicas, incluindo a doença celíaca. Objetivos: Avaliar a prevalência de doença celíaca em pacientes com diagnóstico clínico de síndrome dispéptica e estudar a amostra quanto à epidemiologia, sintomas, achados endoscópicos, histológicos e sorológicos. Método: Estudo observacional, baseado na revisão de prontuários de pacientes atendidos por dispepsia não investigada. Foram incluídos pacientes acima de 18 anos, com essa dispepsia e que possuíssem endoscopia, imunoglobulina A total e antitransglutaminase IgA. Foram excluídos os com quadro diarreico, constipação, má-absorção, intolerância à lactose refratária ou que apresentassem sinais ou sintomas extraintestinais sugestivos de doença celíaca. Resultados: A amostra inicial foi de 1802 registros e a final de 200 pacientes. Destes, 100 apresentavam endoscopia, histologia e dosagem de anticorpos, e os 100 restantes, endoscopia e dosagem de anticorpos, mas não histologia. Considerando o total da amostra a idade média foi de 45,13 anos e o sexo feminino foi predominante. Os sintomas associados ao glúten foram relatados em 6%. O anticorpo antitransglutaminase foi positivo em 1,5%. Considerando a amostra de 100 pacientes, o diagnóstico de doença celíaca teve prevalência de 3%. Conclusão: A prevalência de doença celíaca em pacientes com diagnóstico clínico de síndrome dispéptica foi de 3%.
ABSTRACT
BACKGROUND: Colorectal cancer (CRC) is one of the most common types of cancer in the world. Over time, intestinal epithelial cells undergo mutations that may lead to proliferative advantage and the emergence of cancer. Mutations in the beta-catenin pathway are amongst those described in the development of CRC. AIM: To verify the existence of a relation between the presence of Wnt3, beta-catenin and CDX2 in colorectal cancer samples and clinical outcomes such as disease progression or death. METHOD: Wnt3a, beta-catenin and CDX2 immunohistochemistry was performed on CRC tissue microarray samples (n=122), and analysis regarding the relation between biomarker expression and disease progression or death was performed. RESULTS: No significant difference was found between the presence or absence of CDX2, beta-catenin or Wnt3a expression and clinical stage, tumor grade, disease progression or death. CONCLUSION: CDX2, beta-catenin and Wnt3a are not useful to predict prognosis in patients with CRC.

RESUMO Racional: O câncer colorretal (CCR) é um dos tipos mais comuns no mundo. As células epiteliais intestinais podem sofrer mutações que ocasionam vantagem proliferativa e culminam com o surgimento do câncer. Mutações da via da beta-catenina foram descritas entre as que podem ocasioná-lo. Objetivo: Verificar a existência de relação entre a expressão de Wnt3, beta-catenina e CDX2 em amostras de câncer colorretal com os eventos clínicos progressão de doença e óbito. Método: Foi realizada análise imunoistoquímica de Wnt3a, beta-catenina e CDX2 em blocos multiamostrais de CRC (n=122), e avaliada a relação entre a expressão dos biomarcadores e os desfechos progressão de doença e óbito. Resultados: Não foram encontradas diferenças significativas entre a expressão ou ausência de CDX2, beta-catenina ou Wnt3a e estádio clínico, grau de diferenciação tumoral, presença de progressão de doença ou evolução ao óbito. Conclusão: Os marcadores CDX2, beta-catenina e Wnt3a não são úteis para predizer prognóstico em pacientes com CCR.

O objetivo do presente trabalho foi avaliar as caracteriÌsticas de morbidade dos pacientes de uma unidade de emergência referenciada, atraveÌs de um questionaÌrio que conteÌm o iÌndice de comorbidades de Charlson (ICC), o escore Hospital (EH) e a escala ECOG (EE), além de verificar se os idosos pontuam mais que os demais. Trata-se de um estudo observacional, transversal e descritivo, em que foram avaliados 73 pacientes. A média de idade dos participantes foi de 53,6 anos e os idosos totalizaram 46,6% dos pacientes. A média global de pontos do ICC foi de 4,3, a do EH foi de 4,8, e a da EE foi de 1,1. No grupo dos não idosos, a média do ICC foi de 2,7, enquanto no grupo dos idosos foi de 6,1, com significância estatística. Os resultados obtidos sugerem que a maior parte dos atendimentos de urgência e emergência são de idosos com alta prevalência de comorbidades.
This study aimed to evaluate morbidity information of patients from a referral emergency service, through a questionnaire containing Charlson Comorbidity Index (CCI), Hospital Score (HS) and ECOG performance status (PS), besides verifying if the elderly got higher scores than the others. It is an observational, cross-section and descriptive study, which evaluated 73 patients. The average age of the participants was 53.6 years and 46.6% of them were elderly. The global score average of CCI, HS and PS were, respectively: 4.3, 4.8 and 1.1. The average score of CCI was 1.83 for the non-elderly group, while, for the elderly group, it was 7.72. This was statistically significant. The granted data suggests that the majority of the emergency services is provided to elderly with high prevalence of comorbidities.
