Reduced stroke risk in patients with compromised cerebral blood flow reactivity treated with superficial temporal artery to distal middle cerebral artery bypass surgery.
Extracranial-to-intracranial (EC-IC) bypass surgery for the prevention of stroke in patients with symptomatic carotid artery occlusion has nearly ended after a randomized trial showed no benefit of the procedure. Although an EC-IC bypass might benefit patients with compromised cerebrovascular hemodynamics, the randomized trial did not differentiate patients with hemodynamic from embolic etiologies. However, subsequent investigators have identified a subgroup of patients at increased stroke risk from hemodynamic compromise. ⋯ STA-MCA bypass surgery can restore cerebrovascular reserve in high-risk patients with symptomatic internal carotid artery occlusion. This was achieved with minimal perioperative complications, resulting in a subsequent reduction of stroke frequency. We suggest that the efficacy of STA-MCA bypass surgery for symptomatic carotid occlusion be re-examined prospectively using hemodynamic selection criteria.

Randomized Controlled Trial Clinical TrialEffective analgesia after bilateral tubal ligation.
Postpartum bilateral tubal ligation is a brief surgical procedure with minimal tissue injury, yet postoperative recovery times and analgesia requirements are often disproportionately large. To evaluate the analgesic efficacy of local anesthetic infiltration, 20 parturients scheduled for elective minilaparotomy and bilateral tubal ligation with either spinal or epidural anesthesia participated in this prospective, randomized, controlled, double-blind trial. All patients received IV metoclopramide 10 mg and ketorolac 60 mg intraoperatively, as well as preincisional infiltration of the infraumbilical skin incision with 0.5% bupivacaine. Infiltration of bilateral uterine tubes and mesosalpinx was performed with either 0.5% bupivacaine (n = 10) or isotonic sodium chloride solution (saline) (n = 10). IV meperidine (25 mg every 3 min as needed) was given to treat pain in the postanesthesia care unit (PACU). The total amount of meperidine administered in the PACU was significantly larger in the saline group than in the bupivacaine group. Pain scores at 30, 45, 60, 75, and 90 min postoperatively and on the seventh postoperative day were significantly lower in the bupivacaine group than in the saline group. During tubal ligation, infiltration of uterine tubes and mesosalpinx with 0.5% bupivacaine significantly enhanced analgesia both in the immediate postoperative setting and on the seventh postoperative day compared with infiltration with sodium chloride. ⋯ During bilateral tubal ligation with either spinal or epidural anesthesia, preemptive analgesia using IV ketorolac, IV metoclopramide, and infiltration of the incised skin and uterine tubes with 0.5% bupivacaine allowed 9 of 10 patients to recover with no pain, nausea, vomiting, or cramping and to maintain good analgesia for 7 days postoperatively.

[Cesarean sections in Senegal: coverage of needs and quality of services].
A prospective longitudinal study was carried out of all women undergoing Cesarean section in the surgical maternity hospitals of Senegal between January 1 and December 31 1996. The epidemiology and quality of Cesarean sections were investigated. For each case, the following data were recorded: marital status, prenatal monitoring, conditions of hospitalization, indications for and outcome of surgery, maternal and neonatal follow-up one month after the operation. 2,436 Cesarean sections were performed. ⋯ Maternal morbidity occurred in 10% of cases, mainly due to postoperative infection. The rate of perinatal stress was 25%, most deaths being caused by neonatal distress (33%) or infection (18%). Thus, overall, both the availability and quality of Cesarean section in Senegal are poor.

Although trends in the marketplace demand for neurosurgeons should be of interest to neurosurgeons and prospective neurosurgeons, little data are available that accurately document these trends. A recent report published in the general medical journal Journal of the American Medical Association (JAMA) used the Conference Board help-wanted index to evaluate trends in physician marketplace demand. ⋯ The authors' data suggest that the conclusion of the JAMA study of steep declines in the demand for specialist physicians does not accurately reflect the job market for neurosurgeons, which in fact appears to be relatively stable. The present study attempts to document the stability of the neurosurgery market and outline the steps necessary to protect this market from existing threats.
