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.

Experienced neurosurgeons at eight spinal cord stimulation centers in the United States, Canada, and Europe participated in a study from 1997 to 2000 investigating the safety, performance, and efficacy of a Transverse Tripolar Stimulation (TTS) system invented at the University of Twente, the Netherlands. This device was proposed to improve the ability of spinal cord stimulation to adequately overlap paresthesia to perceived areas of pain. Fifty-six patients with chronic, intractable neuropathic pain of the trunk and/or limbs more than three months' duration (average 105 months) were enrolled with follow-up periods at 4, 12, 26, and 52 weeks. ⋯ The most common complication was lead migration. While the transverse stimulation system produced acceptable outcomes for overall pain relief, an analysis of individual pain patterns suggests that it behaves like spinal cord stimulation in general with the best control of extremity neuropathic pain. This transverse tripole lead and driving system introduced the concept of electrical field steering by selective recruitment of axonal nerve fiber tracts in the dorsal columns.

Complex off-pump coronary artery bypass surgery can be safely taught to cardiothoracic trainees.
Off-pump coronary revascularisation is demanding technically as the surgeon is faced with a beating heart and not a bloodless field. The potential clinical advantages of off-pump coronary revascularisation have made this procedure an essential part of a cardiothoracic training program. The aim of this study is to investigate the impact of teaching trainees complex off-pump coronary artery surgery (arterial grafting, 'Y' grafts, sequential grafting and minimally invasive direct coronary artery bypass) on clinical outcomes. ⋯ The results of this study suggest that trainees under supervision perform complex off-pump coronary artery surgery safely with low rate of mortality and complications. These findings are in agreement with previous literature reports. Trainees should be allowed to operate on sufficient number of patients undergoing off-pump surgery according to their skills and abilities. Patients should be reassured that safety is not compromised by the presence of a trainee as a primary surgeon.
