Even though serious efforts have been undertaken by different medical societies to reduce opioid use for treating chronic benign pain, many Americans continue to seek pain relief through opioid consumption. Assuring compliance of these patients may be a difficult aspect of proper management even with regular behavioral monitoring. ⋯ Our results showed that repeated UDT can improve compliance of patients on opioid medications and can improve overall pain management. We believe UDT testing should be used as an important adjunctive tool to help guide clinical decision-making regarding opioid therapy, potentially increasing future quality of care.Key words: Urine toxicology analysis, chronic pain, opioids, compliance, pain management, urine drug testing, urine drug screening.

The association of paroxysmal hemicrania with trigeminal neuralgia (TN) has been described and called paroxysmal hemicrania-tic syndrome (PH-tic). We report the case of a patient diagnosed as having chronic PH-tic (CPH-tic) syndrome as a clinically isolated syndrome of the central nervous system (CNS) (CIS). A forty year old woman was admitted to our hospital suffering from right facial pain for the last 2 years. ⋯ When dealing with symptomatic cases, like the one described here, when causal therapy is not possible due to the nature of the primary pathological process, a therapeutic approach, although symptomatic, can be fully effective in controlling this painful syndrome. The case report could be a contribution to the pathophysiological and clinical understanding of the association of CPH and TN. Key words: Paroxysmal hemicrania, trigeminal neuralgia, clinically isolated syndrome.

Nonmedical use of opioid medications constitutes a serious health threat as the rates of addiction, overdoses, and deaths have risen in recent years. Increasingly, inappropriate and excessively liberal prescribing of opioids by physicians is understood to be a central part of the crisis. Public health officials, hospital systems, and legislators are developing programs and regulations to address the problem in sustained and systematic ways that both insures effective treatment of pain and appropriate limits on the availability of opioids. ⋯ Academic detailing has successfully affected the management of health conditions, such as atrial fibrillation, chronic obstructive pulmonary disease, and recently, has targeted physicians who prescribe opioids. This article discusses the approach as a potentially effective preventative intervention to address the epidemic of opioid overuse. Key words: Opioid abuse, opioid misuse, academic detailing, health policy, interactive education,prevention.

Enzyme immunoassays (EIA) have notable limitations for monitoring therapeutic compliance in pain management. Chromatography coupled with mass spectrometry provides definitive results and superior sensitivity and specificity over traditional EIA testing. ⋯ Mass spectrometry is a more robust and reliable method for detection of drugs used in the pain management setting. Due to the extent of undisclosed use and abuse of medications and illicit drugs, LC-MS/MS testing is necessary for adequate and accurate drug detection. In addition, LC-MS/MS methods are superior in terms of sensitivity and number of compounds that can be screened, making this a better method for use in pain management. Key words: Pain management, enzyme immunoassays, mass spectrometry, urine drug testing, prescription status, compliance.

Pulsed radiofrequency (PRF) has been widely employed for ameliorating clinical neuropathic pain. How PRF alters electrophysiological transmission and modulates biomolecular functions in neural tissues has yet to be clarified. We previously demonstrated that an early application of low-voltage bipolar PRF adjacent to the dorsal root ganglion (DRG) reduced acute neuropathic pain in animals. By contrast, the present study investigated how PRF alters postsynaptic sensitization to produce early and delayed effects on neuropathic pain. ⋯ Low-voltage bipolar PRF produces LTD through selective suppression on the C-component, but not on the A-component. It also inhibits ERK activation within neurons and astrocytes in SDHs. The findings suggest that PRF alleviates long-lasting neuropathic pain by selectively and persistently modulating C-fiber-mediated spinal nociceptive hypersensitivity.Key words: Pulsed radiofrequency (PRF), dorsal root ganglion (DRG), neuropathic pain, ERK activation, evoked field potential, ATF-3, long-term depression (LTD), spinal nerve ligation (SNL).
