Q fever endocarditis in the United States.

A patient with Q fever endocarditis, which is almost unknown in the United States, was followed for a total of 32 months; the study was begun 3 1/2 months before aortic valve replacement. Diagnosis was confirmed by serology, visualization of Coxiella burnetii in excised aortic valve tissue by direct and immunofluorescence staining, and isolation of C. burnetii from aortic valve tissue. Serum antibodies against phase I and phase II antigens of C. burnetii were identified. Almost all phase I and phase II antibodies were IgG. These findings are compared with those in an uncomplicated case of acute Q fever. New findings on the immune response to chronic Q fever are presented.

Patient-controlled analgesia for postcholecystectomy pain: a pilot study.

Patient-controlled analgesia (PCA) is designed to avoid both excessive and inadequate analgesia in postoperative pain by allowing the patient self-administration of intravenous narcotics within a range of parameters established by the physician. Of 24 patients undergoing elective cholecystectomy referred to our study over a 12-month period, 11 were assigned to PCA and eight successfully completed the study. Most of them had good analgesia, were satisfied with PCA, and had no evidence of confusion, psychic distress, or visual-motor impairment. Serum morphine concentrations of 10-30 ng/mL were sufficient to obtain good analgesia in six of eight patients. Complications included severe respiratory depression and abdominal cramps.
