Alcoholism in Tuberculous Patients

The incidence of alcoholism among patients suffering from tuberculosis in the Tuberculosis Hospital in Winnipeg was determined, and attention is drawn to the need to treat tuberculosis and alcoholism concurrently. In all, 306 patients with tuberculosis were studied and 32 alcoholics were discovered among them. This frequency is five times that estimated in the adult population of Canada. Ninety-two per cent of these alcoholics were addicted before the tuberculous disease was discovered. No direct causative factor was discovered linking alcoholism and tuberculosis. Poor socioeconomic status appears to be a common etiological factor.     

Poikilocytosis in Cancer Patients

The incidence of poikilocytosis in 100 patients with cancer of various organ systems was found to be 12 per cent. Poikilocytosis was more frequently seen in patients with adenocarcinoma of the gastrointestinal tract and with inoperable metastatic carcinoma than in patients with other malignant lesions. Anemia was associated in three cases, but in nine instances the patient was not significantly anemic at admission. Two of these patients may have been dehydrated. Uremia was not a factor in any of the cases.Fifty per cent of the patients exhibiting poikilocytosis died or were in a terminal condition within one month after the observation was made, as compared with 21 per cent of the patients who did not have evidence of poikilocytosis. These findings show that poikilocytosis may occur in cancer patients without anemia or uremia; and they indicate that its presence is an unfavorable prognosis sign.

Determination of Nitrogen in Living Patients

THE technique of in vivo activation analysis has been used in the sequential study of whole-body calcium¹. Neutrons are produced by bombarding a lithium target with 10 MeV protons from the 1.5 m Nuffield cyclotron. The patients, after being irradiated to a dose of about 1.5 rem, are transferred to a whole-body counter in which the activities induced in calcium, sodium and chlorine are monitored. We briefly describe here a new technique for making in vivo measurements on line by counting during the period of irradiation. In particular we have examined the feasibility of measuring the whole-body nitrogen content and of detecting trace amounts of the toxic element cadmium. Liquid phantoms simulating the conditions in the human body are used for these studies.     

Lung Cancer in Younger Patients

Carcinoma of the lung is rare in younger patients, but occasional reports of this condition have appeared in the literature. This article reviews the clinical and pathological patterns of bronchogenic carcinoma in 96 patients, 40 years old or younger seen at UCLA (University of California, Los Angeles) Hospital between 1956 and 1976. This review confirms the finding in other reports of a higher proportion of women among younger patients with lung cancer as well as a relatively low incidence of squamous cell carcinoma. Using comparative data from the UCLA and California tumor registries, we could find no significant difference in survival of the younger patients when compared with the general population of patients with lung cancer.
