Although percutaneous kyphoplasty (PKP) could achieve rapid pain relief for the elderly with osteoporotic vertebral compression fracture (OVCF), some patients still had risks of suffering vertebrae delayed union which led to persisting pain and vertebral collapse. Preventing the delayed vertebral union could reduce the further morbidities and medical costs for patients with OVCF after PKP. ⋯ Preoperative BMD, intravertebral cleft, and restoration rate of vertebral height could be factors independently associated with delayed union of vertebrae after PKP in patients with OVCF.Key words: Percutaneous kyphoplasty, delayed union, osteoporotic vertebral compression fracture.

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.

Spinal cord stimulation (SCS) is a well-established treatment for chronic neuropathic pain in the lower limbs. However, some patients have pain in distributions that are difficult to target specifically and consistently with SCS. This often involves pain in the groin or upper limbs, or pain limited to a specific dermatome. We hypothesized that dorsal nerve root stimulation (DNRS) would provide similar pain relief for these patients, compared to our results using SCS. ⋯ In our study, DNRS provided excellent pain reduction, quality of life improvement, and opioid medication use decreases. We conclude that it is an effective long-term treatment for chronic neuropathic pain.Key words: Spinal cord stimulation, dorsal nerve root stimulation, lumbar, thoracic, cervical, neuropathic pain, neuromodulation, clinical effectiveness, chronic pain, visual analogue scale.

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.
