Background-Many studies have shown that emotional factors play a part in asthma, but few have compared patients with differing severities of asthma. It was our impression that patients with "brittle" asthma (BA; more than 40% diurnal variation in peak flow on 15 or more days a month over a period of at least six months, and persistent symptoms despite multiple drug treatment) had greater psychosocial morbidity than asthmatic patients with less variable asthma.

People with dementia have worse outcomes associated with hospital admission, are more likely to have interventions and are less likely to be offered palliative care than people without dementia. Advance care planning for care home residents has been shown to reduce hospital admissions without increasing mortality. Studies have shown that staff confidence in managing delirium, a common reason for admission, improves with training. A service combining education for care home staff and advance care planning for care home residents with dementia was introduced to care homes in Boston, UK. There were improvements in staff confidence in recognition, prevention, management and knowledge of factors associated with delirium and dysphagia. 92% of carers rated the service >9/10. Admissions fell by 37% from baseline in the first year and 55% in the second and third years. All but one resident died in the preferred place of care.

Physical disease is more prevalent in people with mental disorder than in the general population. It is important for psychiatrists to maintain skills in physical examination to ensure that physical illness is diagnosed and treated appropriately. A sound knowledge of medical illness ensures that examination is targeted at the relevant diseases. Mental health units should provide adequate facilities and equipment. All detailed examinations should be undertaken in the presence of a chaperone. Opportunities for psychiatrists to refresh their knowledge and skill are suggested.

A 13-year-old girl was referred because of sexual identity problems. There was no mental illness or neurological abnormalities. As her twin sister had no sexual identity problems, it appears that transsexualism is not transmitted by a simple genetic mechanism.
