Randomized Controlled Trial
A randomized, double-blind, active-control trial of the effectiveness of lumbar interlaminar epidural injections in disc herniation.
Among the multiple nonsurgical modalities, epidural injections are one of the most commonly utilized treatment modalities in managing chronic low back and lower extremity pain due to disc herniation and radiculitis. There is a paucity of randomized trials from contemporary interventional pain management settings utilizing fluoroscopy with long-term follow-up. ⋯ Lumbar interlaminar epidural injections of local anesthetic with or without steroids is an effective modality, in patients with chronic function limiting low back and lower extremity pain secondary to disc herniation after failure of conservative modalities.

Randomized clinical trials assessing the efficacy and tolerability of tonabersat compared with placebo as prophylaxis for migraine were systematically reviewed in this study. By analyzing all available data, we aimed to establish an overall estimate of any association in order to more accurately inform clinicians and care-givers about how to prevent migraines. ⋯ There is fair evidence for migraine prophylaxis, but a lack of available evidence for tonabersat for migraine prophylaxis. Although tonabersat failed to demonstrate a significantly greater reduction of migraine headache days than placebo, it was well tolerated. Future work should further investigate the utility of tonabersat in the preventive management of migraine.

Quantitative sensory testing (QST), with thermal threshold determinations, is a routine part of the comprehensive clinical workup of patients suffering from chronic pain, especially those with Complex Regional Pain Syndrome seen at our outpatient pain clinic. This is done to quantitatively assess each patient's small fiber and sensory function in a controlled manner. Most patients have normal sensory detection thresholds, but there are large differences in thermal pain thresholds. Some patients display no thermal hyperalgesia, while other patients display severe thermal hyperalgesia when tested in all 4 limbs. ⋯ Thermal QST provides useful information about the sensory phenotype of individual patients. Subgrouping based on thermal hyperalgesia may be useful for future studies regarding prognosis, treatment selection, and efficacy.

Despite hints about the high incidence of pain patients misreporting their pain medication use, there are only a few non-controlled studies on the topic that focus solely on opioids. ⋯ NCT01625065; Medi-3889-10.

Prescription drug abuse is the fastest growing drug problem in the United States, and the increase in unintentional drug overdose deaths has been driven by the increase in opioid analgesic use. Given the epidemic of non-medical prescription pain reliever use and the current medico-legal climate, it is increasingly important for the prescriber to monitor for medication compliance. ⋯ The limitations include the study was performed in a single academic center in an urban community. Also, there is a paucity of literature regarding windows of detection for OF analysis compared to urine.
