Study Design. A retrospective design comparing three matched groups was used to evaluate the application of a multidimensional approach to outcomes analysis using a variety of disease-specific and generic outcome measures to assess three treatments for failed back surgery syndrome. Objective. The objective of this study was to explore the use of a multidimensional analysis of outcomes to compare and contrast the effects of three different treatments: 1) intrathecal therapy using an implantable drug administration system (DAS), 2) standard medical therapy emphasizing the use of oral opioids (OO), and 3) residential pain and rehabilitation program (RPRP) for the treatment of chronic low back pain. Summary of Background Data. The incidence of low back pain in patients with prior back surgery remains significant. ⋯ No one treatment emerged as the most effective across all of the disease-specific and generic measures. However, patients in the DAS group tended to report greater improvement. Overall, although generally "satisfied" with treatment, they were generally "satisfied" with treatment despite continuing to report significant levels of pain, disability, and impaired QoL.

Objective. To use a meta-analysis on all reported cases of deep brain stimulation (DBS) for dystonia to determine which factors significantly influence outcome. The Burke-Fahn-Marsden (BFM) movement scale, the most reported measure, was chosen as the primary outcome measure for this analysis. Methods. A MEDLINE search identified 137 patients who underwent DBS for dystonia in 24 studies that had individual BFM scores. ⋯ Longer duration of dystonia symptoms correlated negatively with surgical outcome. A regression model using the three variables-stimulation site, etiology of dystonia, and duration of dystonia symptoms-explained 51% of the variance in outcomes. Conclusion. Deep brain stimulation of the GPi provides significant improvement in BFM scores in a variety of dystonic conditions.

While inadvertent perioperative hypothermia has received serious attention in many surgical specialties, few discussions of hypothermia have been published in the plastic surgery literature. This article reviews the physiology of thermoregulation, describes how both general and regional anesthesia alter the normal thermoregulatory mechanisms, indicates risk factors particularly associated with hypothermia, and discusses the most effective current methods for maintaining normothermia. Hypothermia is typically defined as a core body temperature of /=36.5 degrees C is maintained. ⋯ None of these measures can be adequately employed unless a patient's core body temperature is monitored throughout the perioperative period. Prevention of perioperative hypothermia is neither difficult nor expensive. Proper preventive measures can reduce the risk of complications and adverse outcomes, and eliminate hours of needless pain and misery for our patients.

CommentConsidering the use of induced hypothermia in a pediatric patient with traumatic brain injury: a critical appraisal of two meta-analyses.
To review whether induced hypothermia after traumatic brain injury affects morbidity and mortality based on the results of two meta-analyses. ⋯ The discrepancies in the results of these contemporaneous meta-analyses may stem, in part, from differences in their trial selection strategies as well as from sources of trial heterogeneity. Nevertheless, McIntyre et al. uncovered the equivalent of a dose-dependent reduction in the risk of death with induced hypothermia, supporting further study of this neuroprotective strategy. Although these meta-analyses included trials containing adult patients, a phase II trial of induced hypothermia in pediatric traumatic brain injury has established its feasibility and safety in infants and children. As in adult patients, induced hypothermia for traumatic brain injury in children can be considered an optional therapy for refractory intracranial hypertension but should not be regarded as standard of care.
