The management of thoracic outlet syndrome induced by bilateral cervical ribs in young, female athlete - a case report.

Introduction: The presence of additional cervical ribs is a rare and relatively unknown pathology. The brachial plexus is most often compressed. Thoracic Outlet Syndrome (TOS) is the one of discussed of mixed compression syndromes, due to diagnostic difficulties and the lack of evidence to resolve the effectiveness of surgical treatment over conservative treatment.

DoD-NCCAM/NIH workshop on acupuncture for treatment of acute pain.

The Department of Defense (DoD) and the National Center for Complementary and Alternative Medicine (NCCAM) at the National Institutes of Health (NIH) cosponsored a workshop that explored the possible benefits of acupuncture treatment for acute pain. One goal of the workshop was to establish a roadmap to building an evidence base on that would indicate whether acupuncture is helpful for treating active-duty military personnel experiencing acute pain. The workshop highlighted brief presentations on the most current research on acupuncture and acute pain mechanisms.

Effect of patient positioning on intra-abdominal pressure monitoring.

Background: Intra-abdominal hypertension affects multiple organ systems. Current measurement standard requires supine positioning, which jeopardizes patient safety by increasing the risk for ventilator-associated pneumonia. This study evaluated the relationship between intra-abdominal pressure (IAP) and head-of-bed (HOB) positioning in critically ill intubated patients.

Pharmacological profile of the alpha4beta2 nicotinic acetylcholine receptor partial agonist varenicline, an effective smoking cessation aid.

The preclinical pharmacology of the alpha4beta2 nicotinic acetylcholine receptor (nAChR) partial agonist varenicline, a novel smoking cessation agent is described. Varenicline binds with subnanomolar affinity only to alpha4beta2 nAChRs and in vitro functional patch clamp studies in HEK cells expressing nAChRs show that varenicline is a partial agonist with 45% of nicotine's maximal efficacy at alpha4beta2 nAChRs. In neurochemical models varenicline has significantly lower (40-60%) efficacy than nicotine in stimulating [(3)H]-dopamine release from rat brain slices in vitro and in increasing dopamine release from rat nucleus accumbens in vivo, while it is more potent than nicotine.

Strain differences in the acquisition of nicotine-induced conditioned taste aversion.

Lewis (LEW) and Fischer (F344) rat strains differ on a variety of physiological and behavioral endpoints, including reactivity to drugs of abuse. Although they differ in drug reactivity, such assessments are generally limited to morphine and cocaine. To determine if these differences generalize to other drugs, the present study examined these strains for their reactivity to the affective properties of nicotine, specifically their sensitivity to nicotine in the conditioned taste aversion preparation.
