Randomized Controlled Trial Comparative Study
Percutaneous Cervical Nucleoplasty Versus Pulsed Radio Frequency of the Dorsal Root Ganglion in Patients with Contained Cervical Disc Herniation; A Prospective, Randomized Controlled Trial.
Cervical neck pain is often caused by cervical disk pathology and may cause severe symptoms and disability. Surgeons and patients are increasingly aware of postsurgery-related complications. This stimulated the clinical usage of minimally invasive treatments such as percutaneous nucleoplasty (PCN) and pulsed radio frequency (PRF). However, scientific evidence on both treatments is limited. ⋯ Within 3 months, both PCN and PRF show significant pain improvement in patients with contained cervical disk herniation, but none is superior to the other. Both treatment options appear to be effective and safe in regular clinical practice.

This analysis compared the therapeutic response of pregabalin in patients with neuropathic pain (NeP) who had been previously treated with gabapentin to the therapeutic response in patients who had not received gabapentin previously. ⋯ The findings presented here support the idea that pregabalin may be used successfully to treat patients with NeP who may be refractory, respond inadequately, or are intolerant to gabapentin. These findings highlight the importance of tailoring treatment of NeP based on individual patient response to different treatments, including the trial of multiple agents within the same mechanistic class.

Dexmedetomidine is an upcoming agent with sedative, anxiolytic, and analgesic properties. This review summarizes empirical evidence for the efficacy of dexmedetomidine as a sole sedative agent, and its effectiveness for small diagnostic and therapeutic procedure, in comparison with other frequently used sedatives. All randomized controlled trials on the effect of dexmedetomidine were reviewed. ⋯ In the adult studies, dexmedetomidine yielded significantly lower pain levels compared to the other sedatives (in 31.25% of the included studies) and significantly more patient satisfaction (68.2%). In studies on children, more favorable results concerning respiratory safety and the level of adequate sedation were found compared to the control sedatives. Implications for future studies are discussed.

Computerized pneumatic cuff pressure algometry (CPA) using the DoloCuff is a new method for pain assessment. Intra- and inter-rater reliabilities have not yet been established. Our aim was to examine the inter- and intrarater reliabilities of DoloCuff measures in healthy subjects. ⋯ Inter-rater reliability was excellent for PT, PTol, and TSI. Similarly, the intrarater reliability for PT and PTol was excellent, while borderline excellent/good for TSI. Therefore, the DoloCuff can be used to obtain reliable measures of pressure pain parameters in healthy subjects.

Randomized Controlled Trial Multicenter Study
Randomized, Double-Blind Trial of Oral Methylnaltrexone for the Treatment of Opioid-Induced Constipation in Patients with Chronic Noncancer Pain.
Subcutaneous methylnaltrexone, a peripherally acting μ-opioid receptor antagonist, improves opioid-induced constipation (OIC) in patients with chronic noncancer pain. An oral methylnaltrexone formulation has been developed. ⋯ Oral methylnaltrexone was efficacious and well tolerated for OIC in patients with chronic noncancer pain, particularly the 450-mg dose.
