RESUMO
Using a prospective, double blind, double dummy protocol, we compared the efficacy of subacromial injection of 40 mg of triamcinalone acetonide versus oral indomethacin, 100 mg/day, in 40 patients with acute rotator cuff tendinitis. Repeat injection and refill of medication was given after 3 weeks, if necessary. At 6 weeks, there was no significant difference between the 2 groups with respect to the percentage of patients who improved (60 vs 66%) or the magnitude of the change of pain and motion variables. This study suggests that there is essentially no difference in the short term efficacy of oral nonsteroidal therapy compared to local corticosteroid injection(s) in the treatment of rotator cuff tendinitis.

A system is described which allows repeated, noninvasive recording of auditory nerve responses in the cat to transient acoustic stimuli using a closed acoustic system. N1 responses to clicks are recorded from a stainless steel ring electrode at the end of a hollow earbar, the tapered end of which is made of insulating plastic. Acoustic stimuli are generated by a dynamic earphone coupled to the earbar. A calibrated probe microphone is also imcorporated into the earbar to measure sound pressure near the tympanic membrane. This allows better stimulus control than is available with free-field systems. To facilitate insertion of the earbar, meatoplasties were performed on all animals. Responses recorded with this system in anesthetized cats are described and compared with those recorded at the round window. Good repeatability of measurements is described for an animal population of 20 domestic cats over a period of several months. For some of these animals, response amplitude varied from one session to another, but response latency, especially for condensation clicks, was consistent. By comparing statistics of multiple measurement of both N1 amplitude and latency for rarefaction and condensation clicks, it is concluded that the N1 latency vs click-level function for condensation clicks provides the most reliable measure of the cat's auditory nerve function.
