Epidemic of louse-borne relapsing fever in Ethiopia.

During summer 1991 an outbreak of louse-borne relapsing fever occurred simultaneously in two transit camps established for prisoners of war being returned from Eritrea at the end of the Ethiopian civil war. Only antibiotic treatment was given at the Bahr Dar camp where the frequency of cases increased for 20 days. Vector control by delousing in addition to antibiotics was given at Mekele camp where the frequency of cases fell over a similar period. This difference was significant (p < 0.001). Furthermore, there was a significant correlation between the decreasing proportion of camp inhabitants that had not been deloused at Mekele camp each day and the numbers of patients with fever (r = 0.89, p < 0.001). Taken together, these results confirm that effective control of an epidemic of louse-borne relapsing fever is dependent on efficient vector control in addition to antibiotic treatment.

An unusual complication of lithotripsy.

The case described illustrates a most unusual course of events due to a perforation in the wall of the bladder during transurethral lithotripsy. Irrigation fluid forced its way retroperitoneally to the mediastinum. The differential diagnostic problems encountered are discussed.

Spinal analgesia with hyperbaric bupivacaine: effects of volume of solution.

The effects of 0.5% bupivacaine 1.5, 2 and 3 ml in 8% glucose was compared in a double-blind study involving 30 patients undergoing spinal analgesia. The time to the onset of maximum segmental spread of analgesia was approximately 15 min for all three volumes. Cephalad spread of analgesia was related to the volume used: 1.5 ml reached T10, 2 ml T8 and 3 ml T7. The duration of analgesia increased with increasing volume, 3 ml producing analgesia in T8-T12 for 1.5-2 h, and in the lumbar region for 2.5-3 h. Increasing the volume increased the extent of motor blockade and speeded up its onset. Significant decreases in arterial pressure were observed in the 2- and 3-ml groups. The changes in heart rate were moderate and not correlated with the amount of drug. Spinal headache occurred in two patients.
