New insights into regional anesthesia in children: new techniques and new indications.
The applications and indications for pediatric regional anesthesia continue to increase. Several recent advances have occurred in the understanding of this technology in children, including improved techniques, alternative drug combinations, as well as prospective investigations to understand the nature and incidence of adverse effects associated with these techniques when used in pediatric patients. The following article will review recent information from the literature concerning various regional anesthetic techniques in children, including caudal epidural block, lumbar and thoracic epidural anesthesia, and peripheral nerve blockade.

According to the fear avoidance model, prolonged disability among patients with chronic nonmalignant pain is due, in part, to an exaggerated fear of pain. At issue in the present study was an attempt to refine the fear-avoidance hypothesis by eliciting estimates of anticipated pain as well as anticipated injury. Along with scores on the Fear Avoidance Beliefs Questionnaire-Work (FABQ-W), a validated measure of fear avoidance, pain and injury expectancies were used as predictors of work disability in a hierarchical regression model. ⋯ After controlling for pain duration, depression, somatization, and current pain severity, pain expectancy alone accounted for 16% of the variance in patients in the chronic group (P < .001) and 33% of the variance in patients in the acute group (P < .001). Both pain and injury expectancies were associated equally with work disability for patients in the acute group (P < .001), but only pain expectancy accounted for variance in the chronic group (P < .001). Fear-avoidance beliefs, in the form of cognitive expectancies, may have as much influence on the duration of disability in patients with acute pain as they do in patients with chronic pain.

Visceral pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain independent of its etiology. Five major pathways by which pelvic pain is transmitted can be identified. ⋯ Long-lasting pain relief with this procedure has been achieved in patients with pelvic cancer pain. However, there is a discrepancy between diagnostic and therapeutic blockade in patients with nonmalignant pain. Because a diagnostic blockade can give significant pain relief in a large variety of patients, it is worthwhile to investigate new methods that provide lasting neural blockade of the superior hypogastric plexus and long-lasting relief of this devastating condition.

La ventilation non invasive est probablement un des progrès majeurs des dix dernières années dans le traitement de l'insuffisance respiratoire aiguë aux soins intensifs. Son efficacité a été démontrée dans plusieurs indications. ⋯ Comme il demeure toujours possible d'intuber le patient en cas d'échec, la VNI peut être tentée dans plusieurs situations cliniques. Finalement, les succès de la VNI dépendent de l'intérêt et de l'expérience de l'équipe soignante.

Comparative Study
Patient attitudes toward physician financial incentives.
Despite concern about the impact of financial incentives on physician behavior, little is known about patients' attitudes toward these incentives. ⋯ Most patients were uncomfortable with 1 or more of the 3 common methods used to pay physicians. Discomfort was highest with capitation and was more likely among wealthier, well-educated, white patients. With capitation increasing nationally, patients' concerns should be considered in the design of compensation agreements.
