Preliminary observations of a novel topical oil with analgesic properties for treatment of acute and chronic pain syndromes.
Essential oxygen oil (OxyRub from CreoMed Inc., Naples, FL, U.S.A.) is a novel topical analgesic currently commercially available in Europe and now available in the U.S.A. It represents an important alternative to other treatments (nonsteroidal anti-inflammatory drugs, acetaminophen, menthol, camphor) for managing mild to moderate acute and chronic pain. Several clinical trials of this oil will be reviewed. ⋯ Based on studies completed, essential oxygen oil has shown itself to be safe, has demonstrated positive analgesic effects for the treatment of acute and chronic pain, and has improved oxygen content in the skin as well as other dermatological parameters.

The role of glia and the immune system in the development and maintenance of neuropathic pain.
Neuropathic pain refers to a variety of chronic pain conditions with differing underlying pathophysiologic mechanisms and origins. Recent studies indicate a communication between the immune system and the nervous system. A common underlying mechanism of neuropathic pain is the presence of inflammation at the site of the damaged or affected nerve(s). ⋯ Following peripheral nociceptive activation via nerve injury, microglia become activated and release pro-inflammatory cytokines such as tumor necrosis factor-alpha, interleukin-1beta, and interleukin-6, thereby initiating the pain process. Microglia propagate the neuroinflammation by recruiting other microglia and eventually activating nearby astrocytes, which prolongs the inflammatory state and leads to a chronic neuropathic pain condition. Our review focuses on the role of glia and the immune system in the development and maintenance of neuropathic pain.

More than 50% of patients presenting to a pain clinic with neck pain may suffer from facet-related pain. The most common symptom is unilateral pain without radiation to the arm. Rotation and retroflexion are frequently painful or limited. ⋯ Therapeutic repetitive medial branch blocks, with or without corticosteroid added to the local anesthetic, result in a comparable short-term pain relief (2 B+). Radiofrequency treatment of the ramus medialis of the cervical ramus dorsalis (facet) may be considered. The evidence to support its use in the management of degenerative cervical facet joint pain is derived from observational studies (2 C+).

The objectives of this study are (1) to describe Lithuanian cancer patients' barriers to pain management as well as pain management outcomes, (2) to check the reliability and validity of the questionnaires used in Lithuanian for the first time, and (3) to formulate patient-centered recommendations for better cancer pain management. ⋯ The authors believe, that to improve cancer pain management in Lithuania (1) more attention should be paid to psychological status of patients, (2) patients should be more educated about the need and consequences of opioid use for cancer pain, and (3) adherence to pain management regimens should be improved.
