Cyclooxygenase-2 inhibitors (coxibs) are associated with less upper gastrointestinal bleeding (UGIB) than traditional nonsteroidal anti-inflammatory drugs (tNSAIDs). However, they also increase the risk of UGIB in high-risk patients. We aimed to identify the risk factors of UGIB in coxibs users. ⋯ Among coxibs users, H. pylori infection and history of PUB were especially important risk factors for UGIB. Further studies are needed to determine whether proton pump inhibitors might play a protective role in these at-risk patients.

Despite the widespread use of opioids for the treatment of cancer pain, results from several surveys consistently show that pain is still prevalent in some patients with malignant diseases. The purinergic P2Y12 receptor is a primary site leading to microglial activation and hyperalgesic pain behaviors and is considered a key regulator in the prevention of the aggravation of clinical pain conditions. Genetic variability in the P2RY12 gene may contribute to individual differences in pain and opioid sensitivity. ⋯ Polymorphisms of the P2RY12 gene may predict individual differences in both cancer and postoperative pain severity; this might be caused by functional alteration of nociceptive neurons through neuron-glia interaction.

Interventional pain management procedures have an important role in the management of chronic pain. The present study seeks to identify the proportion of patients who experience severe pain during pain procedures either with or without sedation. There is then an attempt to identify any association of high pain levels with factors such as age, gender, ethnicity, preprocedure pain level, procedure type, tobacco use, and baseline pharmaceuticals taken for both pain and/or mood disorder management. ⋯ The majority of patients who undergo nonsedated interventional pain management procedures do not experience severe pain. There is a small but appreciable group of subjects who seem to experience severe pain that cannot be correlated to any particular clinical characteristic in a standard patient evaluation. Even with standard conscious sedation, there is no clear best method to ensure patient comfort for this high-pain level group.

This project was designed to test the feasibility and effectiveness of acupuncture therapy given in a group setting for chronic pain. ⋯ Acupuncture therapy offered in the group setting was effective in reducing pain severity, pain interference, and depression in patients with chronic neck, back, or shoulder pain or osteoarthritis. Benefit persisted through the 24-week measure despite no additional treatment. This finding has potentially important implications for improving access to effective acupuncture treatment for patients with limited financial resources.
