Case ReportsTargeted etanercept for discogenic neck pain: uncontrolled, open-label results in two adults.
Etanercept, a recombinant biologic anti-tumor necrosis factor (TNF)-alpha therapeutic, is approved for the treatment of certain autoimmune arthritides by subcutaneous (SC) injection. TNF-alpha has been suggested to play a central role in neuropathic pain and neuronal damage associated with intervertebral disc herniation. Directed local administration of etanercept, in anatomic proximity to the site of disc and neuronal abnormality, may result in an enhanced therapeutic response. ⋯ Etanercept, delivered by targeted SC injection, may be of benefit for selected patients with resistant pain associated with cervical disc disease. Further study of this new treatment modality is warranted.

Randomized Controlled Trial Clinical TrialInhibition of leukotriene biosynthesis by a novel dietary fatty acid formulation in patients with atopic asthma: a randomized, placebo-controlled, parallel-group, prospective trial.
Leukotriene inhibitors and leukotriene-receptor antagonists are effective in the treatment of inflammatory diseases such as asthma. A search of the entirety of MEDLINE using the terms diet plus leukotrienes identified numerous studies that have explored dietary-management strategies to reduce leukotriene levels through supplementation with polyunsaturated fatty acids such as gamma-linolenic acid (GLA) and eicosapentaenoic acid (EPA). However, the search found no studies on the use of combinations of these fatty acids in patients with asthma. ⋯ Daily consumption of dietary GLA and EPA in a novel emulsion formulation inhibited leukotriene biosynthesis in this population of patients with atopic asthma and was well tolerated.

Traditional nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac, ibuprofen, naproxen, and related agents are nonselective inhibitors of both cyclooxygenase-1 (COX-1) and COX-2, which catalyze prostaglandin synthesis. This inhibition accounts not only for the analgesic, anti-inflammatory, and antipyretic effects of these agents, but also for side effects such as gastric mucosal damage and renal toxicity. Substantial evidence suggests that sparing COX-1 is advantageous for gastric safety. ⋯ In clinical trials, valdecoxib was effective for the treatment of osteoarthritis, rheumatoid arthritis, and moderate to severe pain associated with primary dysmenorrhea. As with the other COX-2-selective inhibitors (celecoxib and rofecoxib), valdecoxib appears to produce less gastrointestinal toxicity than conventional nonselective NSAIDs, although some of the relevant clinical studies have been published only as abstracts. Use of valdecoxib should be reserved for patients at risk for NSAID-induced gastrointestinal problems.

ReviewThe use of gabapentin for the treatment of postherpetic neuralgia.
Varicella-zoster virus causes chickenpox and can reemerge later in life to cause herpes zoster or shingles. One of the most common and disabling complications of herpes zoster is postherpetic neuralgia (PHN). ⋯ Gabapentin appears to be effective and well tolerated for the short-term treatment of PHN. However, future controlled studies are needed to determine whether the effectiveness of gabapentin for PHN is maintained for > 2 months, to establish the optimal dose of gabapentin for PHN, and to compare the efficacy of gabapentin with that of other pharmacologic agents used for the treatment of PHN.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA multicenter, randomized, double-blind, double-dummy, placebo- and active-controlled, parallel-group comparison of diclofenac-K and ibuprofen for the treatment of adults with influenza-like symptoms.
The alleviation of influenza-like symptoms, such as fever, headache, and muscle/joint aches and pains, is important so that sufferers can return to their normal daily activities. A flexible dosing regimen is proposed, starting with an initial dose of 2 tablets (2 x 12.5 mg), followed by 1 to 2 tablets every 4 to 6 hours as needed, to a maximum daily dose of 75 mg for up to 3 days for fever and 5 days for pain. This flexible dosing regimen matches the existing over-the-counter dosing regimen of ibuprofen, which allows the patient to adjust the treatment according to the type, duration, and severity of symptoms. ⋯ In this 3-day study, diclofenac-K 12.5 mg taken in a flexible dosing regimen was more effective than placebo in relieving influenza-like symptoms, with comparable tolerability Efficacy and tolerability of diclofenac-K were similar to those of ibuprofen 200 mg.
