The nutritional status of 11 patients with severe mitral valve disease was investigated pre-operatively and 3 months post-operatively. It was shown that they were malnourished pre-operatively, and that this appeared to be related mainly to anorexia.

Gastric ulceration is frequently reported to occur in tumour-bearing animals and man, even when such tumours are not associated with organs of digestion. That central and peripheral dopamine (DA) containing neurones may be relevant to this phenomenon, is supported by the fact that the DA receptor antagonists domperidone (0.1 and 0.05 mg/kg) and pimozide (0.1 mg/kg) were observed to prevent gastric ulceration commonly reported in rats bearing the Walker 256 carcinosarcoma. Daily administration of these drugs prevented the formation of ulcers similar to those observed in vehicle-treated animals. These results demonstrate that DA neurone function is important in the formation of gastric ulcers in tumour-bearing animals and suggest that such compounds may be useful in cancer management.

More than thirty years ago, as a corollary of the experimental analysis of the systemic hypersensitivity reaction, it was postulated that the general symptoms of tuberculous patients may be due to the action of the specific antigen upon the sensitized host. The same hypothesis can be extrapolated in order to interpret some hitherto unexplained findings that are observed in cancer hosts, as well as organ transplant recipients.
