Comparative StudyPsychological characteristics of reflex sympathetic dystrophy versus myofascial pain syndromes.
Reflex sympathetic dystrophy (RSD) has sometimes been hypothesized to derive from a unique psychological predisposition because of its enigmatic features, as well as the profound behavioral and emotional characteristics manifested by some patients. This study compares the psychological characteristics of RSD and myofascial pain syndrome (MPS) patients to discern the extent of any aspects unique to RSD. ⋯ With only a few exceptions, RSD and MPS patients appear comparable with respect to a wide range of demographic, clinical, and psychological functioning indices. A specific psychological profile, uniquely neurotic or otherwise, has yet to be demonstrated in terms of any etiologic or maintenance factors in RSD.

The regional anesthesia "learning curve". What is the minimum number of epidural and spinal blocks to reach consistency?
Wide variability exists in the amount of regional anesthesia practice to which residents are exposed during training. The number of attempts at various blocks before a trainee becomes proficient at performing these regional anesthetic techniques is not known. This study addresses the question: What is the minimum number of blocks a resident must perform to reach consistency during training in these techniques? ⋯ Approximately 20-25 procedures each are necessary before improvement in the techniques of spinal and epidural anesthesia is demonstrated by residents in training. If a 90% success rate is desired, 45 and 60 attempts at spinal and epidural anesthesia, respectively, may be necessary.
