The use of oral mexiletine for the treatment of pain after peripheral nerve injury.

Neuropathic pain is often a difficult condition to treat. Clinical and laboratory studies using intravenously administered local anesthetics or antiarrhythmic agents support the use of these drugs for the treatment of neuropathic pain. The availability of the oral antiarrhythmic medication, mexiletine, has made it possible to study the effects of an orally administered medication on chronic neuropathic pain. The study used a double-blind placebo-controlled design to examine 11 subjects in whom treatment with conventional pain medications had been unsuccessful. Subjects had a history of peripheral nerve injury or dysfunction, and all complained of symptoms consistent with neuropathic pain. After baseline pain measurements, mexiletine or placebo was given in gradually increasing doses to a maximum daily dose of 750 mg mexiletine. After 1 month at steady state, the subject received the alternative medication. Mexiletine was found to produce a statistically significant reduction in reported pain when compared to baseline or placebo. Pain scores were rated on a scale from 0 (no pain) to 10 (unbearable pain). Median pain scores prior to mexiletine were 7, after placebo treatment 7, and while receiving mexiletine (750 mg/day) 4. Side effects were mild and well-tolerated. Mexiletine may be effective in reducing neuropathic pain for patients in whom alternative pain medications have been unsatisfactory.

Diagnostic imaging of heterotopic ossification with coexistent deep-venous thrombosis in flaccid paraplegia.

Heterotopic ossification and deep-venous thrombosis can coexist. This raises potential problems because diagnosis depends heavily on imaging studies, and an ideal imaging study which will cost-effectively and noninvasively diagnose both conditions simultaneously is not readily available. A case of coexistent heterotopic ossification and deep-venous thrombosis in flaccid paraplegia is presented. In this case, deep-venous thrombosis and pulmonary embolus were diagnosed and treatment was begun without knowledge of the coexistent heterotopic ossification. Alternative imaging and laboratory diagnostic strategies are discussed. It was concluded that, at this time, clinical acumen and judicious use of traditional diagnostic alternatives is the best means of selecting appropriate treatment. Awareness of the coexistence of the two conditions are careful attention to the patient's clinical course can minimize treatment delays and resultant morbidity.

Diagnostic ultrasound: its value in acute urinary tract infection in spinal cord injury.

Two cases of acute urinary tract infection in patients with spinal cord injury highlight the complications of calculus and perinephric abscess. Rather than waiting the customary 48 hours to assess response to antibiotics before evaluation for secondary complications, diagnostic ultrasound is advocated upon diagnosis of pyelonephritis. The potential benefits of early imaging seem to far outweigh the negligible risk and expense.
