The Page kidney is a recognized cause of hypertension. A massive subcapsular hematoma caused by a lumbar sympathetic nerve block resulted in a Page kidney. To our knowledge, this sequence has not been reported. Small hematomas may be treated conservatively, but massive subcapsular hematomas should be decompressed when the patient is clinically stable.(More)
Twenty patients with chronic low back pain received 12 lumbar sympathetic injections, in a series of 6 with bupivacaine and a series of 6 with saline. Changes in subjective pain intensity, EMG from paravertebral muscles, joint ranges of mobility, and daily activity levels were measured at multiple intervals throughout treatment and at 3 monthly follow-up(More)
A group of 61 patients with problems of chronic pain were managed though a rehabilitation program based on the principles of operant conditioning. Of these patients, 35 were receiving compensation for work-related accidents, and 26 were receiving no financial compensation for their chronic pain. Of the patients not receiving compensation, 69% (18) made(More)
A double-blind, parallel study was conducted to evaluate the analgesic effect and safety of a single 25 mg oral dose of picenadol, a centrally acting analgesic, and to compare it with a 60 mg dose of codeine and a placebo in patients with postoperative pain. Two sites using similar protocols enrolled a total of 178 inpatients with postoperative pain. Pain(More)
Thirteen patients with interstitial cystitis (IC), whose predominant symptom was pelvic or urethral pain, were treated with a series of lumbar epidural local anaesthetic blocks over an 18-month period. Response was evaluated by interview and with voiding diaries and visual analogue scales (VAS) for pain. Of the 55 injections given, immediate pain relief(More)
The purposes of this study were to evaluate the effect of age on the vascular absorption of local anesthetics during epidural anesthesia and to corroborate the clinical observations of other investigators with respect to age. Using the arbitrary definition of significance (P less than 0.05), the maximum serum levels of lidocaine (Csmax) did not differ(More)
