The management of bicipital tendonitis can be challenging to the clinician. Traditionally, blind injections near the bicipital groove have been performed by clinicians with risk of bicipital tendon rupture or atrophy. Because of the inaccuracy and risk associated with blind bicipital tendon steroid injections, we sought to ascertain whether a fluoroscopically guided steroid injection into the region of the origin of the long head of the bicipital tendon (supraglenoid tubercle) was efficacious. ⋯ A fluoroscopically guided block injected into the supraglenoid tubercle may be effective in the management of bicipital tendonitis.

With few exceptions, anesthesiologists have not received training in the use of immune modulating drugs (IMDs); but recent evidence suggests that such drugs may be effective in reducing chronic pain. We therefore wished to learn how anesthesiologists working in pain medicine might envisage the treatment of their patients with IMDs in the future. We expected that anesthesiologists would want to refer patients for treatment with IMDs to medical colleagues, such as oncologists or rheumatologists, with prior experience in using these drugs, rather than treat these patients within their own practice. ⋯ Contrary to what we had expected, we found that a majority of the respondents would administer IMDs within their own practice, after appropriate training. The overall response rates were 30% and 23%, respectively; therefore, no firm conclusions can be drawn as to the views of the majority of practicing pain specialists. Our findings may have implications for the planning of both health service delivery and training in pain medicine.

Comparative Study Clinical Trial
An open-label comparison of nabilone and gabapentin as adjuvant therapy or monotherapy in the management of neuropathic pain in patients with peripheral neuropathy.
Neuropathic pain (NeP) is prevalent in patients with peripheral neuropathy (PN), regardless of etiology. We sought to compare the efficacy of the cannabinoid nabilone as either monotherapy or adjuvant therapy with a first-line medication for NeP, gabapentin, in a patient population with PN-NeP. Patients diagnosed with PN-NeP were permitted to initiate monotherapy (nabilone or gabapentin) or add one of these two medications (adjuvant therapy) to their existing NeP treatment regimen in a non-randomized open-label nature. ⋯ Sleep adequacy and the sleep problems index within the MOSSS improved in nabilone monotherapy patients in particular. The benefits of monotherapy or adjuvant therapy with nabilone appear comparable to gabapentin for management of NeP. We advocate for head-to-head randomized, double-blind studies for current therapies for NeP in order to determine potential advantages beneficial in this patient population.

Patients taking more than one drug metabolized through the cytochrome P450 (CYP450) enzyme system experience a drug-drug exposure (DDE), which puts them at risk for a potential pharmacokinetic drug-drug interaction (DDI), defined as two or more drugs interacting in such a way that the effectiveness and/or toxicity of one or all drugs are changed. Any patient subjected to a DDE is at risk for a potentially serious DDI, the epidemiology of which has not been thoroughly studied. Many drugs are metabolized primarily via the CYP450 enzyme system, including certain opioids used to manage moderate to severe chronic pain. ⋯ The risk of DDE during the study period was threefold greater for patients with one medication in the 90-day period before index date compared with similar patients with no prescriptions in that same period before the index date. DDEs are more common than may be generally believed in patients with osteoarthritis, regardless of age, and can occur even in patients taking few medications. When selecting an opioid analgesic to treat osteoarthritis, physicians should consider the potential for exposure of these patients to drugs that could interact unfavorably.
