Long-term incidence of chronic postsurgical pain after thoracic surgery for lung cancer: a 10-year single-center retrospective study.
The long-term incidence of chronic postsurgical pain (CPSP) after thoracic surgery has not yet been reported. ⋯ Our study showed a decreasing trend in the incidence of CPSP as well as delayed-onset or recurrent CPSP after thoracic surgery. A better understanding of the progression of CPSP after thoracic surgery may provide important information on its prediction and treatment.

Meta AnalysisSerotonin-norepinephrine reuptake inhibitors for the prevention of migraine and vestibular migraine: a systematic review and meta-analysis.
The role of serotonin-norepinephrine reuptake inhibitors (SNRIs) in migraine prophylaxis has not been completely established. Current treatments for vestibular migraine (VM) are based on scarce evidence. We aimed to perform an updated review focusing on the efficacy and tolerability of SNRIs for migraine and VM prevention. ⋯ SNRIs were clinically safe and effective for migraine and VM prophylaxis, were better than a placebo, and not inferior to other active drugs. SNRIs may be a preferable choice for patients with VM with psychiatric disorders.

Postdural puncture headache in the obstetric population: a new approach?
The gold standard for the treatment of postdural puncture headache (PDPH) is the epidural blood patch (EBP). Regional techniques-sphenopalatine ganglion block (SPGB), greater occipital nerve block (GONB) and trigger point infiltration (TPI)-can also be used for the treatment of PDPH. Our objective was to evaluate the efficacy of these peripheral nerve blocks (PNBs) in the treatment of PDPH. ⋯ SPGB, GONB and TPI can be safe and effective options for treatment of PDPH, but do not completely eliminate the need for EBP. Prospective studies designed to identify factors associated with unsuccessful treatment are required.

Intertruncal approach to the supraclavicular brachial plexus, current controversies and technical update: a daring discourse.
We propose a new approach to local anesthetic injection for the supraclavicular brachial plexus block: an intertruncal approach by which local anesthetic is deposited in the two adipose tissue planes between the upper and middle and the middle and lower trunks. We present sonographic and microscopic images to illustrate the relevant anatomy. ⋯ It also offers an advantage over the 'intracluster' approach as it purposefully avoids intraneural injection respecting the integrity of the epineurium of individual trunks. Comparative studies are required to confirm that these anatomic and technical advantages result in improved outcomes.

Randomized Controlled Trial Comparative StudyComparison of the effectiveness of circumferential versus non-circumferential spread in median and ulnar nerve blocks. A double-blind randomized clinical trial.
Circumferential (C) spread of local anesthetic around the nerve is recommended for a successful nerve block. We tested the hypothesis that C spread produces a more complete block than non-circumferential (NC) spread. ⋯ C spread around the median and ulnar nerves at the level of the antecubital fossa generates more complete sensory and motor blocks compared with NC spread.
