ABSTRACT BACKGROUND: Maritime transportation is an activity of vital importance for societies. The Mar Grande-Salvador crossing is an intercity waterway transport line in Brazil that transports 3,500 passengers/day, including residents and tourists. In 2017, an accident on this crossing was considered to be the biggest maritime tragedy in Bahia in the last decade. OBJECTIVE: To describe the clinical and epidemiology characteristics of victims of this maritime accident, with analysis on bodily injuries, causes of death and means/instruments that caused the fatal injuries. DESIGN AND SETTING: Case-series study at the Forensic Medical Institute of Bahia, Brazil. METHODS: Reports on 73 victims who were examined for bodily injury or were necropsied by the Forensic Medical Institute were analyzed. This study was approved by the institution’s Research Ethics Committee (protocol 04012218.1.0000.5032). RESULTS: The victims’ mean age was 33.0 years [95% confidence interval, CI, 26.3-47.0]. The mean age of those who died was 43.0 years [95% CI, 30.5-53.5]. Bodily injuries were found in 74% of the victims. The most frequent bodily injuries were ecchymoses among females (69.7%) and abrasions among males (76.2%). Blunt instruments produced most bodily injuries (85.2%). Among the victims who died, 68.4% were female. Mechanical asphyxiation through drowning was the leading cause of death (89.4%). The overall lethality rate was 26%, and this was higher among females (28.2%). CONCLUSION: Women were the main victims of this maritime accident. Bodily injuries occurred more frequently than death, but these injuries proved to be quite significant, thus demonstrating the importance of measures to improve the safety of navigation.

RESUMO Objetivo: Analisar os principais achados endoscópicos nos pacientes com idade inferior a 40 anos e as principais indicações para realização das colonoscopias. Métodos: Estudo retrospectivo, com análise de 362 laudos de pacientes com idade inferior a 40 anos submetidos à colonoscopia, no período de Janeiro de 2014 até Junho de 2017 no serviço de coloproctologia do Hospital Geral Roberto Santos. Foi realizado preparo de cólon com manitol e os pacientes foram submetidos à sedação á critério do anestesista. Resultados: Dos 362 pacientes analisados, 192 (53%) eram do sexo feminino. Em relação à idade: média de 25 anos (25,58 ± 11,95). As indicações mais frequentes foram doença inflamatória intestinal em 24,3% (88) dos pacientes, sangramento digestivo baixo em 24% (87); e diarreia crônica 20,2% (73). Os principais achados colonoscópios foram polipose em 21,3 (77) dos pacientes e alterações inflamatórias em 20,7% (75). Conclusão: Com análise dos dados fornecidos pelos exames colonoscópios e suas indicações foi possível concluir que quando a investigação é adequada e o exame é bem indicado, mesmo abaixo dos 40 anos, a colonoscopia pode auxiliar no diagnóstico e tratamento de diversas patologias, inclusive as que podem aumentar o risco de câncer colorretal.

ABSTRACT Objective: To analyze the main endoscopic findings in patients under 40 years of age and the main indications for colonoscopy in these patients. Methods: A retrospective study with 362 reports of patients under 40 years of age who underwent colonoscopy from January 2014 to June 2017 at the colonoscopy service of the General Hospital Roberto Santos. Colon preparation was performed with mannitol and the patients underwent sedation as the anesthetist criteria. Results: Of the 362 patients analyzed, 192 (53%) were female. The mean age was 25 years (25.58 ± 11.95). The most frequent indications were inflammatory bowel disease in 24.3% (88) of the patients, bleeding in the lower digestive tract in 24% (87), and chronic diarrhea in 20.2% (73). The main colonoscopic findings were polyposis in 21.3% (77) of the patients and inflammatory alterations in 20.7% (75). Conclusion: With the analysis of the data provided by the colonoscopies, it was possible to conclude that, when the investigation is adequate and the examination is well indicated, even under the age of 40, colonoscopy can help in the diagnostic and treatment of several pathologies, including those that may increase the risk of colorectal cancer.

RESUMO Introdução: A colonoscopia mostra-se útil no diagnóstico de diversas patologias. Ao permitir a visualização direta da mucosa, possibilita a tomada de medidas terapêuticas, como a remoção de pólipos, dilatação de estenoses e realização de biopsias. Tal método pode ser empregado também no rastreio do câncer colorretal, que atualmente representa importante causa de mortalidade no mundo. Os indivíduos considerados de médio risco para o desenvolvimento do câncer colorretal, devem iniciar a triagem a partir dos 50 anos de idade, a fim de detectar precocemente a doença. Objetivo: Descrever os principais achados e indicações dos exames daqueles pacientes que realizaram colonoscopia com idade ≥ 50 anos. Método: Estudo descritivo, em série de casos, referente a 1.614 colonoscopias realizadas no período de 2014 a 2017 em hospital de referência em Salvador, BA. Resultados: As principais indicações para realização do exame foram sangramento intestinal (26,5%), rastreio de neoplasia (20,7%) e dor abdominal (10,2%). Os principais resultados encontrados foram doença diverticular (38,9%), pólipos (38,8%) e exame normal (23,2%). Os pacientes com indicação de rastreio de neoplasia tiveram como principal achado, a presença de pólipos (41,3%). Dos pacientes com exame normal; 28,8% apresentaram sangramento intestinal como indicação. Houve 70,0 (4,3%) pacientes com diagnóstico colonoscópico de neoplasia. Conclusão: O presente estudo, ao demonstrar uma maioria de exames com alterações consideráveis, evidencia a utilidade do exame, além de outras vantagens, como uma forma de diagnóstico do câncer colorretal.

ABSTRACT Introduction: Colonoscopy has shown to be useful in the diagnosis of various pathologies. By allowing the direct visualization of the mucosa, colonoscopy allows the adoption of therapeutic methods, such as the removal of polyps, dilation of stenoses, and biopsies. This method can also be applied in the detection of colorectal cancer, which currently represents an important cause of mortality in the world. Individuals considered to be at medium risk for the development of colorectal cancer should start screening at 50 years of age in order to detect early disease. Objective: To describe the main results of the exams for patients at least 50 years old who underwent colonoscopy. Method: Descriptive, case-series study of 1614 colonoscopies performed from 2014 to 2017 at a referral hospital in Salvador, Bahia. Results: The main indications for the study were intestinal bleeding (26.5%), neoplasia screening (20.7%), and abdominal pain (10.2%). The main results were diverticular disease (38.9%), polyps (38.8%), and normal examination (23.2%). Patients with indications for neoplasia screening had the presence of polyps (41.3%) as their main diagnosis. For patients with normal examination, 28.8% presented intestinal bleeding as an indication. There were 70 (4.3%) patients with a colonoscopic diagnosis of neoplasia. Conclusion: The present study, which demonstrated a majority of exams with considerable alterations, shows the usefulness of the examination, besides other advantages, as a form of diagnosis of colorectal cancer.
