Mimics and chameleons in stroke.

Ischaemic stroke is a treatable medical emergency. In an era of time-dependent reperfusion techniques, it is crucial that an accurate and prompt diagnosis is made. Approximately 30% of patients admitted to hyperacute stroke units are subsequently found not to have a final diagnosis of acute stroke although some of these patients do have incidental or previously symptomatic cerebrovascular disease.

Junior doctors' understanding of alcohol units remains poor.

A survey of 586 trainee doctors in Yorkshire was undertaken to ascertain current junior doctors' knowledge and understanding of alcohol units. Approximately 18% of trainees had no knowledge of alcohol units despite the fact that 82% believed they had a good knowledge. Once again, those who did not drink alcohol knew less about alcohol units than those who did.

Adequacy of endobronchial ultrasound transbronchial needle aspiration samples in the subtyping of non-small cell lung cancer.

Introduction: The histological subtyping of non small cell lung cancer (NSCLC) is important in the selection of the optimal treatment for patients with advanced disease. There are now important differences in the chemotherapy regimens used for squamous and non-squamous cancers. Non-squamous cancers (particularly adenocarcinomas) are also suitable for targeted therapy if the epidermal growth factor receptor (EGFR) genetic mutation is present.

Impact of prescribed medications on patient safety in older people.

Appropriate prescribing for older adults presents unique challenges to the prescriber. An understanding of the scale of the problems and contributing factors is essential when designing interventions to improve patient safety. The altered pharmacology of ageing, the existence of multiple medical conditions and the exclusion of elderly patients from many trials render this subgroup of the population particularly vulnerable to underprescribing and overprescribing.
