Despite more than a century of existence as a clinical entity, the true origin of ulcerative colitis still remains elusive. Several factors probably contribute to the development of this condition. Recently discovered technologies have clarified the role of bacterial species, which may account for intestinal dysbiosis, as a factor triggering ulcerative colitis. ⋯ Although the genetic background has been more clearly recognised in patients with Crohn's disease than in those with ulcerative colitis, some candidate loci associated with ulcerative colitis have also been intensively studied. Additionally, environmental factors may interfere with inherent predispositions to ulcerative colitis, and either suppress or reinforce them. Whatever the origin, the search for the aetiology of ulcerative colitis must have the same goal: the improvement of treatment and the quality of life in patients with ulcerative colitis.

Daily in the UK, frontline medical and paramedical staff are required to manage patients with "collapse ?cause". This universal colloquialism refers to patients who have had an abrupt loss of postural tone. Some of these patients would have had a "blackout" or a transient loss of consciousness (T-LOC). ⋯ This fact is not well appreciated and often leads to misdiagnosis. This article deals with the clinical features of the three main causes of blackouts, the value of investigations in arriving at a diagnosis and the problem of misdiagnosis. Pathways for managing patients presenting with blackouts are suggested.

Coronary heart disease is the most common cause of death in Western countries, with a rising incidence in developing countries. It is part of the spectrum of cardiovascular diseases that have common end points of myocardial infarction, stroke and death. ⋯ Besides the known traditional risk factors, direct imaging of the calcified plaque as a marker for atherosclerotic disease has been extensively studied with electron beam computed tomography and now with multislice computed tomography. This review discusses the role of computed tomography in assessment of cardiovascular risk in both people with or without symptoms.

Twenty four hour ambulatory blood pressure monitoring (24-H ABPM) plays an important part in the management of subjects with suspected and confirmed disorders of blood pressure regulation. This article reviews the prognostic significance of various aspects of the 24-H ABPM and describes the authors experience in Chesterfield. ⋯ Fifty two (4.38%) of the subjects had all of the seven features associated with an adverse prognosis. Only 82 (6.90%) subjects had none of the seven adverse prognostic features with the remainder having one or more adverse prognostic features.
