In several cases we also detected an osteitis, especially of the bodies of the vertebræ. One was of the cervical vertebræ and the other of the dorsal. The first died after intense suffering. An autopsy was not obtained. The other had a plaster cast applied as in Pott’s disease, and improved sufficiently to leave the hospital in comfort. One hesitates under the circumstances to attribute these bone lesions definitely to the same infecting micro-organism which was responsible for the epidemic of influenza, as it might easily have happened that a coincident quiescent tuberculous lesion was present and relighted during the epidemic. However, in one case from the service of Dr. J. O. Wallace the possibility of the bone lesions being due to the Pfeiffer bacillus was demonstrated. This was a child of 16 months with an epiphysitis of the upper end of the tibia. The inflamed area was incised and pus was found. A smear at the time showed the B. influenzæ, which was grown in pure culture. A most interesting complication noted in a few of our cases was a transient glycosuria. The first case brought to our attention was a middle-aged female, who complained of failure of vision. Upon making an ophthalmoscopic examination a papillitis of a mild type was noticed. This led to a careful study of the urine, and sugar was found in a small amount for a short period of three days, although the glycosuria readily disappeared by cutting down the carbohydrate intake, the vision came back to normal more slowly. In fact, it was almost one month before the symptoms and signs of the retinal change had entirely disappeared. It is interesting in this connection to recall similar cases referred to in Allbutt’s System of Medicine, vol. vi, on influenza, following the epidemic of 1890 in England. Other transient glycosurias showed no visual changes. We do not consider these to be true cases of diabetes mellitus. In all a transient hyperglycæmia was also noted. _Pregnancy_ A condition which can scarcely be considered as a complication of influenza, but which, however, was a large factor in increasing the mortality among women, was pregnancy. Among the cases included in this study were five pregnant women, who came to the hospital and were referred to the medical service. As soon as a complication relative to the existing pregnancy arose they were referred to the Obstetrical Department. On account of the great amount of work in caring for the influenzal patients, and on account of the scarcity of physicians and nurses, we were unable to follow these cases closely enough to give any such definite data as we wish. Three miscarried or went into premature labor. Happily only one of them died. The two which did not miscarry recovered and left the hospital well.
