Randomized Controlled Trial Multicenter Study Comparative Study
Duloxetine Compared with Pregabalin for Diabetic Peripheral Neuropathic Pain Management in Patients with Suboptimal Pain Response to Gabapentin and Treated with or without Antidepressants: A Post Hoc Analysis.
To examine the efficacy of duloxetine vs. pregabalin in the treatment for diabetic peripheral neuropathic pain (DPNP), comparing patient subgroups with and without concomitant antidepressant use. ⋯ In patients with DPNP inadequately treated with gabapentin without the concomitant use of antidepressants, switching to duloxetine instead of pregabalin may provide better pain reduction. Conversely, in nonresponders to gabapentin who are concomitantly using an antidepressant, switching to duloxetine or pregabalin may provide similar pain reductions.

The Effects of Exercise Therapy for the Improvement of Jaw Movement and Psychological Intervention to Reduce Parafunctional Activities on Chronic Pain in the Craniocervical Region.
Apparent organic abnormalities are sometimes not identified among patients suffering from chronic pain in the craniocervical region. In some cases, parafunctional activities (PAs) are recognized. PAs are nonfunctional oromandibular activities that include jaw clenching and bruxism, but are considered as factors that contribute to craniomandibular disorders (CMDs). It is now recognized that PAs and CMDs influence musculoskeletal conditions of the upper quarter. Exercise therapy (ET) to improve jaw movement and psychological intervention (PI) to reduce PAs are useful for PAs and CMDs. We hypothesized that ET and PI would be effective for craniocervical pain without organic abnormalities. ⋯ A combination of jaw exercise and psychological intervention to reduce parafunctional activities is more effective than jaw exercise alone for the improvement of craniocervical pain without apparent organic abnormalities.

Efficacy and Safety of Low Dose Subcutaneous Diclofenac in the Management of Acute Pain: A Randomized Double-Blind Trial.
Diclofenac is an effective and well-tolerated nonsteroidal anti-inflammatory drug (NSAID) frequently used in the treatment of acute pain. Marketed formulations for parenteral administration usually contain 75 mg/3 mL of diclofenac sodium, which provide limited dosing flexibility, and are usually given intramuscularly. ⋯ Single SC doses of diclofenac HPβCD of 25 and 50 mg are effective and well tolerated for relieving pain compared with placebo.

Efficacy and Safety of Carisbamate in Patients with Diabetic Neuropathy or Postherpetic Neuralgia: Results from 3 Randomized, Double-Blind Placebo-Controlled Trials.
The results of 3 proof-of-concept studies to evaluate carisbamate's efficacy and safety in treating neuropathic pain are presented. In studies 1 (postherpetic neuralgia, n = 91) and 2 (diabetic neuropathy, n = 137), patients received carisbamate 400 mg/day or placebo for 4 weeks and then crossed over to the other treatment for 4 weeks. In study 3 (diabetic neuropathy, higher carisbamate doses), patients (n = 386) were randomized (1:1:1:1) to receive either carisbamate 800 mg/day, 1200 mg/day, pregabalin 300 mg/day or placebo for 15 weeks. ⋯ Neither carisbamate (all 3 studies) nor pregabalin (study 3) significantly differed from placebo, although multiple secondary end points showed significant improvement in efficacy with carisbamate in studies 1 and 2. Dizziness was the only treatment-emergent adverse event occurring at ≥10% difference in carisbamate groups versus placebo (study 1: 12% vs. 1%; study 3: 14% vs. 4%; study 2: 1% vs. 2%). Carisbamate, although well tolerated, did not demonstrate efficacy in neuropathic pain across these studies, nor did the active comparator pregabalin (study 3).

Effects of Intra-Operative Ketamine Administration on Postoperative Catheter-Related Bladder Discomfort: A Double-Blind Clinical Trial.
Urinary catheterization during surgery frequently leads to unfavorable signs and symptoms (ie urgency, discomfort, frequency) during recovery. These signs and symptoms are collectively called catheter-related bladder discomfort (CRBD). We hypothesized that preemptive IV ketamine administration prior to intra-operative catheterization would reduce the incidence of CRBD in the postoperative period when compared to placebo. ⋯ Preemptive administration of IV ketamine (0.5 mg/kg) can reduce incidence and severity of CRBD in the early postoperative period.
