Trauma remains the leading cause of death under the age of 35 years. England and Wales lost 252,000 working years from accidental deaths, including poison, in 1992. In this country, preventable deaths from trauma are inappropriately high. ⋯ Even if the recommendation is made to establish such centres, it is unlikely that many will be set up. Consequently most hospitals will have to rely on their own resources to set up and run a trauma team. This type of trauma care system is the subject of this article.

Cough is one of the commonest symptoms of lung disease and is a frequent problem encountered in general practice as well as in hospital practice. A wide range of disease processes may present with cough and definitive treatment depends on making an accurate diagnosis of the cause. A diagnostic work-up for patients with persistent dry cough is presented. ⋯ An increased sensitivity of the cough reflex can be observed in patients with persistent dry cough. Symptomatic relief must be considered when the cough interferes with the patient's health and sleep but the most effective antitussive opiates cause sedation and may be addictive. Treatment of persistent dry cough remains a challenge in some patients and there is still scope for improvement in its diagnosis and effective therapy.

Nitric oxide has been determined to be a potential mediator of the haemodynamic changes associated with sepsis. The haemodynamic eects of nitric oxide can be partially antagonised by methylene blue, through inhibition of the enzyme, guanylate cyclase. The case report presented here demonstrates a beneficial haemodynamic eect of continuous infusion of methylene blue during sepsis. These findings could be extrapolated to other patients or prompt additional research.
