Unexplained Fever : Seven Year Experience

SummaryA retrospective analysis was made of the cases of unexplained fever observed at a University Hospital during the period of time between 1965 and 1972. Of 165 charts reviewed, 80 satisfied the criteria set for admission in this study group. A definitive diagnosis was reached in 60 (75 %) These diagnoses are presented in table form. Tuberculosis was found in 7 cases (8.7 %). The importance of considering a therapeutic trial with tuberculostatic drugs in stressed. In connection with this study, a group of 36 patients with “low grade fever” was analysed. This group consisted mainly of younger females. A diagnosis, which remained tentative at best in a fair proportion of cases, could only be reached in 48 % of this group. It is suggested that hormonal contraception may represent a cause of “low grade fever”, to be considered in times to come.
