Randomized Controlled Trial
Can predictors of response to NSAIDs be identified in patients with acute low back pain?
The aim of this study was to determine whether certain patient characteristics could identify people with acute low back pain who were more likely to respond to nonsteroidal anti-inflammatory drugs (NSAIDs), when administered in combination with paracetamol. ⋯ This study did not find any baseline patient characteristics, which consistently identified patients with acute low back pain who respond best to NSAIDs when provided in addition to paracetamol and advice. A patient's sex and level of fear avoidance may be weak predictors and warrant further prospective investigation.

Randomized Controlled Trial
A randomized, controlled, dose-ranging study investigating single doses of GW406381, naproxen sodium, or placebo in patients with acute pain after third molar tooth extraction.
To evaluate the efficacy and tolerability of 4 doses of GW406381, a cyclooxygenase-2 inhibitor, compared with placebo in a standard model of acute inflammatory pain. ⋯ GW406381 50 and 70 mg demonstrated clinically meaningful analgesia in this acute pain setting, although the onset of analgesia was greater than 1 hour.

Randomized Controlled Trial
Plasma vitamin C is lower in postherpetic neuralgia patients and administration of vitamin C reduces spontaneous pain but not brush-evoked pain.
Plasma vitamin C concentrations have been suggested to be related to pain modulation in postherpetic neuralgia (PHN), an intractable neuropathic pain syndrome. In this study, we first compared plasma concentrations of vitamin C between healthy volunteers and PHN patients and then designed a symptom-based and mechanism-based approach to assess the analgesic effect of intravenous vitamin C on spontaneous and brush-evoked pain. ⋯ Plasma vitamin C status plays a role in PHN, and intravenous ascorbate helps relieve spontaneous pain in PHN.

Randomized Controlled Trial
A single point acupuncture treatment at large intestine meridian: a randomized controlled trial in acute tonsillitis and pharyngitis.
One out of 4 patients visiting a general practitioner reports of a sore throat associated with pain on swallowing. This study was established to examine the immediate pain alleviating effect of a single point acupuncture treatment applied to the large intestine meridian of patients with sore throat. ⋯ A single acupuncture treatment applied to a selected area of the large intestine meridian was no more effective in the alleviation of pain associated with clinical sore throat than sham laser acupuncture applied to the same area. Hence, clinically relevant improvement could be achieved. Pain alleviation might partly be due to the intense palpation of the large intestine meridian. The benefit of a comprehensive acupuncture treatment protocol in this condition should be subject to further trials.

Randomized Controlled Trial Comparative Study Clinical Trial
Opioid-sparing effects of ketorolac and its correlation with the recovery of postoperative bowel function in colorectal surgery patients: a prospective randomized double-blinded study.
Postoperative ileus (PI) is one of many common complications in major abdominal surgery. PI results in patient discomfort, increased gastrointestinal leakage, prolonged hospital stay, and increased medical expenses. In this study, we have investigated the morphine-sparing effects of ketorolac and its correlation with the duration of PI in patients with colorectal surgeries. ⋯ The addition of ketorolac to IVPCA morphine has demonstrated a clear opioid-sparing effect and benefits in regards to the shortening of the duration of bowel immobility. We suggest that adding ketorolac to morphine IVPCA be included in the multimodal postoperative rehabilitation program for the early restoration of normal bowel function.
