Acknowledgements This study received no specific funding. The study involved the analysis of data collected routinely as part of the national AAA screening programme in Scotland.

Why do children have chronic abdominal pain, and what happens to them when they grow up? Population based cohort study

Objective: To test the hypotheses that children with abdominal pain have anxious parents and come from families with high rates of physical illness and that they grow up to suffer from high rates of medically unexplained symptoms and psychiatric disorders.

Long term relative survival after surgery for abdominal aortic aneurysm in Western Australia: population based study

Objective: To determine the long term relative survival of all patients who had surgery for abdominal aortic aneurysm in Western Australia during 1985-94.

Automatic Abdominal Aortic Aneurysm segmentation in MR images

Abdominal Aortic Aneurism is a disease related to a weakening in the aortic wall that can cause a break in the aorta and the death. The detection of an unusual dilatation of a section of the aorta is an indicative of this disease. However, it is difficult to diagnose because it is necessary image diagnosis using computed tomography or magnetic resonance. An automatic diagnosis system would allow to analyze abdominal magnetic resonance images and to warn doctors if any anomaly is detected. We focus our research in magnetic resonance images because of the absence of ionizing radiation. Although there are proposals to identify this disease in magnetic resonance images, they need an intervention from clinicians to be precise and some of them are computationally hard. In this paper we develop a novel approach to analyze magnetic resonance abdominal images and detect the lumen and the aortic wall. The method combines different algorithms in two stages to improve the detection and the segmentation so it can be applied to similar problems with other type of images or structures. In a first stage, we use a spatial fuzzy C-means algorithm with morphological image analysis to detect and segment the lumen; and subsequently, in a second stage, we apply a graph cut algorithm to segment the aortic wall. The obtained results in the analyzed images are pretty successful obtaining an average of 79% of overlapping between the automatic segmentation provided by our method and the aortic wall identified by a medical specialist. The main impact of the proposed method is that it works in a completely automatic way with a low computational cost, which is of great significance for any expert and intelligent system.

Hipotermia terapêutica no traumatismo crânio-encefálico

Enquadramento – A hipotermia terapêutica consiste na redução controlada da temperatura central dos doentes com objetivos terapêuticos pré-definidos, assumindo-se actualmente como uma mais-valia no tratamento clínico de vítimas com TCE. Objetivos – Avaliar a eficácia da HT intra-hospitalar na redução da morbilidade e mortalidade do adulto vítima de TCE. Métodos – Foi realizada uma revisão sistemática da literatura sobre a eficácia da HT intrahospitalar na redução da morbilidade e mortalidade do adulto vítima de TCE. Efetuou-se uma pesquisa na PUBMED, The Cochrane Library, Scielo e Google Académico de estudos publicados entre 1 de janeiro de 2012 a 31 de agosto de 2014. Partindo dos critérios de inclusão previamente definidos, os estudos selecionados foram posteriormente avaliados. Dois revisores avaliaram a qualidade dos estudos a incluir, utilizando a grelha para a avaliação crítica de um estudo de Ascenção et al. (2008). Resultados – Quatro artigos preencheram os critérios de inclusão, tendo-se constituído como corpus amostral. Como metasíntese e seleção da análise dos artigos, inferiu-se que os potenciais benefícios neuroprotetores da hipotermia terapêutica, sem efeitos colaterais negativos, deve ser implementada como parte do quotidiano de tratamento e controlo das vítimas de TCE e não como terapia de resgate. Contudo, a validação das implicações práticas da HT carece de mais estudos, cuja indução seja fator neuroprotetor, independentemente do valor da PIC, individualizando a duração da indução da hipotermia. Conclusão – Os benefícios da HT em adultos vítimas de TCE são ainda alvo de debate, requerendo a realização de mais metanálises e ensaios clínicos, visando a atualização das suas recomendações.
