Case ReportsFentanyl tolerance in the treatment of cancer pain: a case of successful opioid switching from fentanyl to oxycodone at a reduced equivalent dose.
Opioids are not generally deemed to have an analgesic ceiling effect on cancer pain. However, there have been occasional reports of tolerance to opioid development induced by multiple doses of fentanyl. The authors report a case of suspected tolerance to the analgesic effect of opioid, in which an increasing dose of fentanyl failed to relieve the patient's cancer pain symptoms, but opioid switching to oxycodone injections enabled a dose reduction to below the equivalent dose conversion ratio. ⋯ Despite the total daily dose of fentanyl reaching 5.6 mg (equivalent to 560 mg oral morphine), the analgesic effect was inadequate; thus, an urgent adjustment was necessary. Due to the moderate dose of fentanyl, the switch to oxycodone injection was done incrementally at a daily dose equivalent to 25% of the fentanyl injection. The total dose of oxycodone was replaced approximately 53.5% of the dose of fentanyl prior to opioid switching.

Case ReportsImprovement in chronic low back pain in an obese patient with topiramate use.
The objective of this study was to demonstrate efficacy, benefit, and potential use of topiramate in treating obese patients with chronic low back pain. This is a case report from an outpatient academic pain multidisciplinary clinical center. ⋯ Over a period of a 12-week topiramate therapy, the patient experienced clinically meaningful and significant weight loss as well as improvement in her chronic low back pain and functionality. With more substantial evidence, pain physicians may start considering using topiramate in the multimodal management of obesity-related chronic low back pain based on their thoughtful consideration of the drug's efficacy and side effects and the patient's comorbidities and preferences.

Editor's Note The journal is delighted to introduce a new feature in this issue that focuses on the complex and multifaceted issue of managing pain and related symptoms while responsibly attending to minimizing substance abuse. How should the seemingly disparate disciplines of drug abuse and symptom control interact? Should these be two separate fields or should practitioners/investigators in one also be qualified in the other? Is that even feasible? We are honored to have two leading, academically based clinician scientists coordinating this new feature. Peggy Compton is Professor and Associate Dean for Academic Affairs at the School of Nursing & Health Studies, Georgetown University in Washington, DC. ⋯ Lipman, Editor ABSTRACT Abusers of prescription opioids represent two distinct populations: those who develop addiction via opioids prescribed for pain, and those for whom prescription opioids represent a primary drug of abuse. Regardless of the pathway to abuse, outcomes for patients with untreated opioid addiction are poor, and consideration of the contextual factors surrounding their problematic use is critical to effective treatment. Reviewed are patterns of prescription opioid abuse among particularly vulnerable populations in underserved rural communities, and in an effort to prevent problematic use, principles of responsible opioid prescription for chronic pain are outlined so as to decrease the risk for developing addiction.

Observational StudyA pilot evaluation of a hydromorphone dose substitution policy and the effects on patient safety and pain management.
Hydromorphone is a potent opioid analgesic commonly utilized in the hospital setting for the management of acute pain. Initial dose recommendations range from 0.1 to 2 mg of hydromorphone for opioid-naïve patients. This creates a challenge to optimally dose hydromorphone in opioid-naïve patients with the goals of avoiding opioid toxicities while also providing adequate pain management. ⋯ The primary outcome of the study was the incidence of opioid toxicity. The secondary outcome of the study was adequate pain management. The results of this study showed no difference in opioid toxicity; however, patients required less per day hydromorphone and other opioids while still adequately managing patients' pain.

Case ReportsTrigeminal neuralgia: unilateral episodic facial pain.
Trigeminal neuralgia is a rare cause of episodic unilateral facial pain and often in the initial presentation dental causes need to be eliminated, as it frequently presents in the lower trigeminal divisions. The pain description is characteristic of electric shock-like pain that is light-touch provoked, paroxysmal, and occurring daily; the condition can go into remission for weeks or months, however. The first-line drug is either carbamazepine or oxcarbazepine and has to be started in low doses. ⋯ Patients need to be given information about all treatment options so they can make a decision about treatment.
