To determine the effectiveness of cervical medial branch thermal radiofrequency neurotomy in the treatment of neck pain or cervicogenic headache based on different selection criteria. ⋯ Higher degrees of relief from cervical medial branch thermal radiofrequency neurotomy are more often achieved, to a statistically significant extent, if patients are selected on the basis of complete relief of index pain following comparative diagnostic blocks. If selected based on lesser degrees of relief, patients are less likely to obtain complete relief.

Observational Study
Evaluation of Using the Sphygmomanometer Test to Assess Pain Sensitivity in Chronic Pain Patients vs Normal Controls.
Objectively measuring pain sensitivity has not been easy in primary care clinics. A sphygmomanometer test (a sensory test that measures an individual's nociceptive response to pressure using a standard blood pressure cuff) has recently been established to test pain sensitivity. Here, we examined the feasibility of using the sphygmomanometer test with chronic pain patients. ⋯ Our results indicate the unique characteristics of the sphygmomanometer test as a pain sensitivity test, particularly when utilized for individuals with chronic pain. Multiple pain sensitivity tests that assess various sensory modalities are needed to evaluate pain sensitivities in chronic pain patients.

Randomized Controlled Trial
Analgesic Effect of Intrathecal Fentanyl vs Dexmedetomidine as Adjuvants to Bupivacaine Following Abdominal Surgery for Cancer in Children, a Randomized Trial.
Intrathecal fentanyl in spinal anesthesia improves intra- and postoperative analgesia. Dexmedetomidine is a fascinating adjuvant with regards to neuraxial anesthesia in children experiencing surgery for abdominal malignancy. ⋯ Adding dexmedetomidine and fentanyl to intrathecal bupivacaine improved postoperative analgesia following abdominal surgery for cancer in children, with better overall analgesia of dexmedetomidine compared with fentanyl.
