[Blood picture changes in patients hospitalized in an internal medical department]
One quarter, i.e. 810 of 3621 patients admitted to a medical department showed quantitative abnormalities of the blood picture even when leukocytosis is excluded. In contrast, only in 113 cases were hematological diseases the main diagnoses on the hospital charts. 18% of the patients hospitalized for the first time had anemia. On analysis of blood changes according to their causes, 28% were found to be of either iatrogenic or toxic origin, the two causes exhibiting roughly the same frequency. The incidence of iatrogenic and toxic blood changes was equal to that of blood abnormalities due to malignant disease including hemoblastoses. Alcohol and phenacetin were the most frequent exogenous toxins, while anticoagulant, immunosuppressant and ulcerogenic drugs were the most frequent iatrogenic causes of abnormalities.
