Endogenous and exogenous opioids are substrates of the permeability glycoprotein (P-gp) efflux transporter, which is encoded by the ABCB1 (MDR1) gene. Genetic polymorphisms of ABCB1 may contribute to interindividual differences in pain modulation and analgesic responses. We investigated the relationship between ABCB1 polymorphisms and cold pain sensitivity among healthy males. ⋯ The CGC/CGC diplotype of ABCB1 polymorphisms was associated with variability in cold pain threshold and pain tolerance in healthy males.

Randomized Controlled Trial
Sufentanil Sublingual Tablet 30 mcg for the Management of Pain Following Abdominal Surgery: A Randomized, Placebo-Controlled, Phase-3 Study.
Results from a phase-3, prospective, randomized, double-blind, placebo-controlled trial evaluating sufentanil sublingual tablet 30 mcg (SST) for the management of pain after ambulatory abdominal surgery are presented. ⋯ In patients following abdominal surgery in an ambulatory care setting, SST was an effective opioid analgesic in postoperative pain management. In addition, SST was well tolerated with mild-to-moderate side effects, similar to those found in placebo-treated patients.

Review
Postoperative Pain Control Following Craniotomy: A Systematic Review of Recent Clinical Literature.
Pain intensity after craniotomy is considered to be moderate to severe during the first 2 postoperative days. The ideal pain treatment to facilitate a rapid postoperative recovery and optimize outcome is unknown. ⋯ No definite recommendations can be made based on this systematic review of pharamacological interventions following craniotomy due to significant divergence in the methodology of available studies. Limited evidence on scalp infiltration/block suggests an adequate analgesic effect in the early postoperative period. Analgesic efficacy of dexmedetomidine and multipoint electro-acupuncture needs further evaluation.

Epidural blood patch is the gold standard for the treatment of postdural puncture headache (PDPH) when conservative treatments have failed to provide any relief. However, alternative therapies are lacking when epidural blood patch persistently fails to improve symptoms. Failure to treat PDPH may lead to significant functional impairment of daily living. Alternative therapies should be sought to accelerate recovery from PDPH. ⋯ Percutaneous injection of fibrin glue to seal the dural defect demonstrated promising outcomes for both immediate and long-lasting resolution of persistent PDPH in our patient. In the event of epidural blood patch failure, epidural fibrin glue patch may be a reasonable alternative for the treatment of persistent PDPH.

Randomized Controlled Trial Comparative Study
A Prospective Study Comparing Platelet-Rich Plasma and LA/Corticosteroid in Intra-Articular Injection for the Treatment of Lumbar Facet Joint Syndrome.
To compare the effectiveness and safety between autologous platelet-rich plasma (PRP) and Local Anesthetic (LA)/corticosteroid in intra-articular injection for the treatment of lumbar facet joint syndrome. ⋯ Both autologous PRP and LA/corticosteroid for intra-articular injection are effective, easy, and safe enough in the treatment of lumbar facet joint syndrome. However, autologous PRP is a superior treatment option for longer duration efficacy.
