Increased risk of paclitaxel-induced peripheral neuropathy in patients using clopidogrel: a retrospective pilot study.
Paclitaxel-induced peripheral neuropathy (PIPN) is one of the serious adverse events associated with paclitaxel-based cancer treatments. A recent case study showed that the antiplatelet agent clopidogrel inhibits paclitaxel metabolism via cytochrome P450 (CYP) 2C8, resulting in severe PIPN. The aim of this study was to determine the impact of clopidogrel as a risk factor for the development of PIPN, using a retrospective cohort study. ⋯ No patients in the aspirin group presented with severe neuropathy. These pilot data suggest that concomitant treatment with clopidogrel leads to a greater risk of PIPN. The avoidance of concomitant clopidogrel use may be effective in reducing clopidogrel-associated PIPN.

Randomized Controlled Trial Comparative StudyComparison of the coracoid and retroclavicular approaches for ultrasound-guided infraclavicular brachial plexus block.
This prospective randomized study compared the coracoid and retroclavicular approaches to ultrasound-guided infraclavicular brachial plexus block (IBPB) in terms of needle tip and shaft visibility and quality of block. We hypothesized that the retroclavicular approach would increase needle tip and shaft visibility and decrease the number of needle passes compared to the coracoid approach. ⋯ The retroclavicular approach is associated with better needle tip and shaft visibility, reduced performance time and anesthesia-related time, less paresthesia during block performance, and fewer needle passes than the coracoid approach.

Review Meta AnalysisAdjuncts to local anaesthetics in tonsillectomy: a systematic review and meta-analysis.
The infiltration of local anaesthetic agents has been shown to reduce post-tonsillectomy pain. A number of recent studies have shown that the addition of agents such as clonidine and dexamethasone improve the efficacy of nerve blocks and spinal anaesthesia. The aim of this review was to determine whether additives to local anaesthetic agents improve post-tonsillectomy outcomes. ⋯ There is limited evidence that pethidine and tramadol have a similar effect on pain and analgesia requirement. The studies in this pooled analysis are sufficiently strong to make a level one recommendation that the addition of magnesium to local anaesthetics reduces the incidence of laryngospasm, a potentially lethal post-operative complication. Review level of evidence: 1.

Feasibility, reliability, and validity of the Japanese version of the 12-item World Health Organization Disability Assessment Schedule-2 in preoperative patients.
The avoidance of postoperative functional disability is one of the most important concerns of patients facing surgery, but methods to evaluate disability have not been definitively established. The aim of our study was to evaluate the feasibility, reliability, and validity of the Japanese version of the 12-item World Health Organization Disability Assessment Schedule-2 (WHODAS 2.0-J) in preoperative patients. ⋯ The WHODAS 2.0-J is a feasible, reliable, and valid instrument for evaluating preoperative functional disability in surgical patients.
