Randomized Controlled Trial Multicenter Study Comparative Study
Comparison between the Combination of Gabapentin, Ketamine, Lornoxicam, and Local Ropivacaine and Each of these Drugs Alone for Pain after Laparoscopic Cholecystectomy: A Randomized Trial.
The main purpose of the study was to test whether the combination of gabapentin (600 mg 4 hours before surgery, 600 mg after 24 hours), ketamine (0.3 mg/kg before anesthesia), lornoxicam (8 mg before anesthesia and 8 mg/12 hours), and local ropivacaine (5 mL 7.5% at insertion sites) provides superior analgesia to each of these drugs alone in the first 24 hours after laparoscopic cholecystectomy. The secondary purpose was to examine whether this combination has less opioid-related side effects. ⋯ The combination of gabapentin, ketamine, lornoxicam, and local ropivacaine does not provide superior analgesia than gabapentin alone or lornoxicam alone after laparoscopic cholecystectomy. The combination reduces only the frequency of postoperative nausea, but larger studies are needed for safer results.

Randomized Controlled Trial Clinical Trial
The Effect of Methylnaltrexone on the Side Effects of Intrathecal Morphine after Orthopedic Surgery under Spinal Anesthesia.
Methylnaltrexone is a peripheral opioid receptor antagonist that does not cross the blood-brain barrier; so without interference with pain relief, it could reverse the peripheral opioid side effects such as constipation, pruritus, postoperative ileus, and urinary retention. This study has been designed to evaluate the effect of methylnaltrexone on postoperative side effects of intrathecal morphine. In seventy-two 18- to 55-year-old patients scheduled for elective orthopedic operations under spinal anesthesia, neuraxial blockade was achieved using 10 mg 0.5% hyperbaric bupivacaine and 0.1 mg preservative-free morphine sulfate. ⋯ Pain score was significantly lower in group M. Respiratory depression or decreased level of consciousness was not reported in any patient. Subcutaneous administration of methylnaltrexone was not effective in decreasing postoperative urinary retention and pruritus, but lowered the rate of nausea and vomiting and pain score after intrathecal bupivacaine and morphine.

Randomized Controlled Trial
Assessment of Pain and Activity Using an Electronic Pain Diary and Actigraphy Device in a Randomized, Placebo-Controlled Crossover Trial of Celecoxib in Osteoarthritis of the Knee.
The primary goal was to determine whether a composite measure of pain and activity is a more responsive assessment of analgesic effect than pain alone or activity alone in patients with osteoarthritis (OA) of the knee. ⋯ We have identified composite pain-activity measures that are similarly or more responsive than pain-alone measures in patients with OA. Further research is warranted to determine the optimal method for computing these composites.

Randomized Controlled Trial
Can We "Predict" Long-Term Outcome for Ambulatory Transcutaneous Electrical Nerve Stimulation in Patients with Chronic Pain?
Evidence for effectiveness of transcutaneous electrical nerve stimulation (TENS) is still inconclusive. As heterogeneity of chronic pain patients might be an important factor for this lack of efficacy, identifying factors for a successful long-term outcome is of great importance. ⋯ The results showed that factors associated with a successful outcome in the long term are dependent on definition of successful outcome.

Randomized Controlled Trial
Single Paravertebral Injection for Acute Thoracic Herpes Zoster: A Randomized Controlled Trial.
The aim of this study was to evaluate the efficacy of single thoracic paravertebral injection in acute thoracic herpes zoster (HZ) pain, eruptive duration, and the incidence of postherpetic neuralgia (PHN). ⋯ Early single paravertebral blockade in the course of acute thoracic HZ seems to be a safe and effective adjuvant treatment modality.
