How far does a doctor's 'duty of care' go?

It is a long-standing tradition in medicine that doctors have an ethical duty to care for all patients who fall within the scope of their skill base. This duty reflects the value system of many doctors and the type of typical dedication to their craft that has long been expected and given. The modern doctor, however, may have other additional roles -- such as those of parent, researcher, business person and many others. What about the duties that accompany these other activities and what if these duties come into conflict with the duty to care for patients? How does a doctor decide how far the duty to care for patients extends? This article explores this question of duty and discusses how the notion of the traditional doctor's duty to care may need to be amended in light of the kinds of lives that doctors now lead.

The pathology of human and murine pulmonary infection with Cryptococcus neoformans var. gattii.

Human infection by Cryptococcus neoformans var. neoformans is well characterised and usually occurs in immunocompromised patients. Less is known about infection by Cryptococcus neoformans var. gattii, which usually produces disease in previously normal individuals. In two cases of human pulmonary infection by Cryptococcus neoformans var. gattii, we observed a mixed inflammatory pattern, including granulomas associated with numerous T lymphocytes and a lymphocytic interstitial pneumonitis with B lymphocytes and formation of follicles. We also established a murine model of pulmonary infection by Cryptococcus neoformans var. gattii, which reproduced most of these features. This model is likely to prove useful in studies of the pathogenesis of this infection.

Toxoplasmosis. Are cats really the source?

BACKGROUND: Toxoplasmosis is a zoonotic infection caused by the parasite Toxoplasma gondii. It would appear to be one of the commonest human infections, but is usually asymptomatic. It is only problematic if the patient is pregnant or immunosuppressed. OBJECTIVE: To discuss the epidemiology, clinical features, diagnosis, treatment and prevention of toxoplasmosis. DISCUSSION: Cats have long been blamed for playing a major role as the reservoir of this infection. To some extent, this is true, although contact with infected raw meat is probably a more important cause of human infection in many countries. Direct contact with pet cats is also a less common risk factor for infection than ingestion of the oocyst from faecally contaminated hands (often via soil).
