Inflammatory bowel diseases: time of diagnosis, environmental factors, clinical course, and management - a follow-up study in a private inflammatory bowel disease center (2003-2017).

BACKGROUND: The governmental program of Brazilian Unified National Health System has already published studies on the incidence of inflammatory bowel diseases (IBD), but up until now, there have been no epidemiological studies in private centers in Brazil. However, these diseases tend to affect people from a higher socioeconomic class, mainly in the capital of MS state that has the third highest GDP in Brazil. OBJECTIVES: The aim was to analyze an observational, descriptive study of an IBD database in a private center including: the side, behavior of the disease and medical management, the association of extra-intestinal manifestations, and the main clinical symptoms which led to the investigation and diagnosis of IBD. PATIENTS AND METHODS: A cohort study was developed in which data of all patients with IBD were analyzed with SPSS software in a constructed electronic database. RESULTS: Of 329 patients, 212 (64.4%) had Crohn's disease (CD) and 117 (35.6%) had ulcerative colitis (UC). Average age at diagnosis of CD was 36.19 (±14.33) and of UC was 41.61 (±15.37). An amount of 50.05% of the patients with CD and 72.7% (P<0.001) with UC were female. We have observed that concerning the first symptoms, diahrrea and blood feces corresponded to 70% in UC while in CD 50% of the patients presented diahrrea with blood feces, loss of weight corresponded to 50% and only diahrrea 25%. (P<0.001). Anti-TNFs corresponded to 56.2% being more frequent in CD 0.001%. CD patients used biologic therapy and antibiotics more frequently than those with UC. In conclusion, IBD is also frequent in private health care centers in Brazil; women are most affected. Symptoms such as diarrhea and bleeding, as well as diarrhea and weight loss, must be taken as warning signs to investigate for inflammatory disease. The use of biologic therapies is frequent in referral centers when patients have severe disease.

Classificação endoscópica do megaesôfago / Endoscopic CLassification of megaesophagus

Apesar de apresentar diminuição em sua incidência, a doença de Chagas aina é a terceira doença tropical mais frequente. A endoscopia digestiva alta (EDA) cresce em importância como metódo auxiliar para eses pacientes, principalmente na avaliação da mucosa e diagnóstico de neoplasias. Até o presente momento, não se encontra na literatura uma classificação para padronizar a descrição das alterações endoscópicas nos pacientes com megaesôfago. Tal classisficação que tivesse boa correlação radiológica, poderia facilitar o tratamento desses pacientes, reduzindo o número de exames. Objetivos: Apresentar uma proposta de classificação endoscópica para pacientes com megaesôfago. Material e Método: Sessenta e cinco pacientes consecutivos com megaesôfago foram avaliados por dois endoscopistas experientes, cegos entre si, durante um único exame. A análise estatistica realizada pelo teste de Kappa, comparando os resultados obtidos com os achados radiológicos pela classificação de Rezende, além de análise da variaçãointerobservador. resultados: Os endoscopistas apresentaram indice de concordância excelenmte (K= 0,90) quando comparados entre si e concordâancia forte (K=0,67) quando comparados com a classificação radiológica. Conclusões: Esta classificação pode ser útil, já que parece haver boa concordância com os achados radiológicos e ser facilmente reproduzida. Novos estudos são necessários para comprovar os benefícios de sua utilização na prática clínica.

[Colonoscopy or sigmoidoscopy: risk of isolated right colon lesions]. / Colonoscopia ou sigmoidoscopia: risco de lesões isoladas no cólon direito.

BACKGROUND: Colorectal cancer is an important cause of death in western countries. Screening methods are based on flexible sigmoidoscopy, a cheap, effective, and less painful procedure, but some important lesions on the right colon can be missed. AIM: Evaluate how many important lesions would be missed if colonoscopy indicated only for patients with distal lesions identified during flexible sigmoidoscopy. MATERIAL AND METHODS: All consecutive colonoscopy performed in the Endoscopy Unit of the Gastroenterology Division of Federal University of São Paulo, SP, Brazil, with polyps and cancer suspicious lesions were reviewed. Patients with a second procedure, inflammatory bowel disease or colonic surgery were excluded. RESULTS: We reviewed 101 patients with 38 possible cancer lesions and 70 polyps. The mean age was 62 years (SD 13.7 years) and 45 were male. Forty five lesions were in the right colon, namely 23 adenomas, 10 adenocarcinomas, 1 lymphoma and 11 benign lesion. Among such lesions, 28 were isolated in the right colon (16 adenomas and 7 adenocarcinomas). CONCLUSION: In our study 23 patients (22.77%) had adenomas or adenocarcinomas isolated in the right colon, that would be missed if flexible sigmoidoscopy was used alone.
