Comparative Study
Selecting an appropriate medication for treating neuropathic pain in patients with diabetes: a study using the U.K. and Germany Mediplus databases.
To evaluate the appropriateness of prescribing select neuropathic pain medications to diabetes patients based on the potential for drug-drug interactions with medications diabetes patients were prescribed continuously for > or =3 months (chronic use). ⋯ Our findings underscore the need for medical vigilance when selecting medications for treating neuropathic pain in diabetes patients.

Recently, ultrasonography has been increasingly used in the field of regional anesthesia to assure reliable blockade of peripheral nerves and to visualize neuroaxial structures. As its popularity is steadily increasing, it may become a standard of care for both intraoperative analgesia and postoperative pain control. ⋯ Nonetheless, numerous articles have been published and some interventionalists have gained experience and started to spread their knowledge through hands-on workshops and medical meetings. It, therefore, seems timely to describe the techniques of ultrasound-guided injections for chronic pain, to review accumulated experience in this field, to reappraise the scientific and clinical value of this method, and to outline potential future developments.

Review
Evidence for the use of botulinum toxin in the chronic pain setting--a review of the literature.
A significant proportion of chronic pain is of musculoskeletal origin. Botulinum toxin (BTX) has been successfully used in the treatment of spasmodic torticollis, limb dystonia, and spasticity. Investigators have, thus, become interested in its potential use in treating many chronic pain conditions. ⋯ There is conflicting evidence relating to the use of BTX in the treatment whiplash, myofascial pain, and myogenous jaw pain. It does appear that BTX is useful in selected patients, and its duration of action may exceed that of conventional treatments. This seems a promising treatment that must be further evaluated.

Spinal cord stimulation is increasingly utilized as a treatment to alleviate low back pain and lumbar radiculopathy, particularly in patients with failed back surgery syndrome. We present an illustrative case of early, rapidly progressive methicillin-resistant Staphylococcus aureus (MRSA) infection after a brief stimulator trial lead implantation. ⋯ Subsequent surgical intervention, however, may nevertheless still be needed. While a variety of bacteria may cause epidural abscess, methicillin sensitive Staphylococcus aureus, and increasingly, MRSA and community-associated MRSA, are the most likely etiologic organisms.

Multicenter Study Clinical Trial
Patient-controlled analgesia in chronic pain patients: experience with a new device designed to be used with implanted programmable pumps.
Intrathecal drug delivery using implantable pumps is an effective method to control stable chronic pain. However, the appropriate alleviation of unpredictable pain fluctuations remains challenging. A possible solution is the use of patient-controlled analgesia (PCA) by means of a specific device--the personal therapy manager (PTM)--designed to be used with implanted programmable pumps. ⋯ Patient-controlled analgesia using a PTM with a programmable, implantable pump system is an effective therapy for the treatment of chronic pain and allows patients to feel that they have more control over unpredictable pain fluctuations.
