The emergence level of the musculocutaneous nerve from the brachial plexus: implications for infraclavicular nerve blocks.
In this cadaveric study we assessed the level of the emergence of the musculocutanous nerve (MCN) relative to needle insertion site during infraclavicular block. ⋯ This anatomical study suggests that MCN may be one of the factors explaining MCN block failure for the single-injection technique of infraclavicular block using lateral needle trajectory.

A survey of anesthesiologists' views of operating room recycling.
Operating rooms contribute significantly to the increasing volumes and costs of hospital waste. Little is known, however, about doctors' views of hospital waste recycling despite their potential influence in improving recycling programs. We surveyed the waste recycling views held by anesthesiologists in Australia, New Zealand, and England in regional or metropolitan and public or private practice. We asked the following: (1) What proportion of anesthesiologists consider recycling operating room waste to be important? (2) What do respondents consider to be identifiable barriers preventing operating room recycling? ⋯ Most responding anesthesiologists supported greater operating room waste recycling but thought that there were identifiable barriers. Anesthesiologists could take a leadership role and work with other hospital employees to improve operating room recycling. We suggest studies of the effect of improving operating room recycling facilities, education, and staff attitudes.

Members of the Society for Pediatric Anesthesia (SPA) perceive the 47% rain rate has burdened its national meetings more than would be expected. We compared weather conditions on the first day of each national SPA meeting since 1987 with historical data using the day, month, and location of each meeting. Using a generalized estimating equations model, the odds ratio of rain comparing meeting and nonmeeting days was 2.63 (P value 0.006, 95% confidence interval 1.32-5.22). These results confirm a significantly higher frequency of rain at national SPA meetings than would be anticipated.

Prevention of paclitaxel-induced neuropathy through activation of the central cannabinoid type 2 receptor system.
Peripheral neuropathy is a major dose-limiting toxicity of chemotherapy, especially after multiple courses of paclitaxel. The development of paclitaxel-induced neuropathy is associated with the activation of microglia followed by the activation and proliferation of astrocytes, and the expression and release of proinflammatory cytokines in the spinal dorsal horn. Cannabinoid type 2 (CB(2)) receptors are expressed in the microglia in neurodegenerative disease models. ⋯ Our findings suggest an innovative therapeutic approach to prevent chemotherapy-induced neuropathy and may permit more aggressive use of active chemotherapeutic regimens with reduced long-term sequelae.
