Randomized Controlled Trial Multicenter Study
A Randomized, Placebo-Controlled Trial of Ibuprofen Plus Metaxalone, Tizanidine, or Baclofen for Acute Low Back Pain.
Patients with low back pain are often treated with nonsteroidal anti-inflammatory drugs and skeletal muscle relaxants. We compare functional outcomes and pain among patients with acute low back pain who were randomized to a 1-week course of ibuprofen plus placebo versus ibuprofen plus 1 of 3 skeletal muscle relaxants: baclofen, metaxalone, and tizanidine. ⋯ Adding baclofen, metaxalone, or tizanidine to ibuprofen does not appear to improve functioning or pain any more than placebo plus ibuprofen by 1 week after an ED visit for acute low back pain.

Multicenter Study Observational Study
Clinical Subtypes of Medication Overuse Headache - Findings From a Large Cohort.
The International Classification of Headache Disorders lists different subtypes of medication overuse headache (MOH), according to the medication overused. The aim of this study is to evaluate whether the different subtypes correspond to clinically distinguishable phenotypes in a large population. ⋯ In this study on a large and very well characterized population of MOH, we describe the distinctive clinical characteristics of MOH subtypes. These findings contribute to more clearly define the clinical picture of a poorly delineated headache disorder. They also provide some insights in the possible trajectories leading to this highly disabling chronic headache, that is classified as a secondary form, but whose occurrence is entirely dependent on an underlying primary headache.

Multicenter Study Observational Study
Incidence and risk factors for epidural morphine induced pruritus in parturients receiving cesarean section: A prospective multicenter observational study.
This study is designed to clarify the incidence of epidural morphine induced pruritus (EMIP) in Chinese Han and Tibetan parturients after cesarean section (CS) and to identify the correlated risk factors. This is a prospective multicenter observational study. Follow-up evaluations were performed at 3 hours, 6 hours, 12 hours, 24 hours, and 48 hours after morphine administration. ⋯ In conclusion, EMIP incidence in our study was 18.6%. Positive medical history of allergy and not using serotonin receptor antagonist were potential risk factors of EMIP development. Trial registration: ChiCTR-OPC-17012345.

Randomized Controlled Trial Multicenter Study
Onset of action of naldemedine in the treatment of opioid-induced constipation in patients with chronic noncancer pain: results from 2 randomized, placebocontrolled, phase 3 trials.
Opioid-induced constipation (OIC) is a common side effect of chronic opioid therapy. Previously, naldemedine, a peripherally acting μ-opioid receptor antagonist demonstrated efficacy in the treatment of OIC. In this exploratory analysis, the onset of action of naldemedine was evaluated in 2 identically designed phase 3, randomized, placebo-controlled trials. ⋯ Treatment-emergent adverse events were reported most frequently on day 1, followed by a decrease from days 2 to 7. Naldemedine had a timely onset of effect, and gastrointestinal adverse events largely resolved within the first week. These findings should assist clinicians counseling patients with chronic noncancer pain on expectations when initiating naldemedine for OIC.

Randomized Controlled Trial Multicenter StudyEfficacy and Safety of an Intravenous Acetaminophen/Ibuprofen Fixed-dose Combination After Bunionectomy: a Randomized, Double-blind, Factorial, Placebo-controlled Trial.
Multimodal analgesia with acetaminophen and/or nonsteroidal anti-inflammatory drugs is recommended for the treatment of postoperative pain. Although oral fixed-dose combinations (FDCs) are available, parenteral administration may be clinically justified. The goal of this study was to investigate the clinical efficacy and safety of an intravenous FDC of ibuprofen and acetaminophen after bunionectomy. ⋯ The study found that repeated administration of an intravenous FDC of ibuprofen and acetaminophen provided statistically significant improvement in SPID48 over comparable doses of either monotherapy without an increase in adverse events. ClinicalTrials.gov identifier: NCT02689063.
