Buprenorphine Patches in Diabetic Peripheral Neuropathy

Transdermal buprenorphine may be an effective therapy for diabetic peripheral neuropathic pain (DPNP). However the treatment was associated with a high rate of adverse events, mostly nausea and/or vomiting. The findings come from a newly published multi-center, randomized, double-blind, placebo-controlled, parallel-group trial. Ninety-three patients with type 1 or 2 diabetes were enrolled and received either buprenorphine (5μg/h) or placebo patches. All the patients had been experiencing moderate to severe DPNP for a minimum of 6 months on maximal tolerated conventional therapy. The dose was titrated to effect to a maximum of 40μg/h for the study. Results showed that of those…

Sacral Neuromodulation for Sacrectomy Patients

Chronic Pain Conditions, Spinal Cord Stimulation, Therapies & Treatmentsneuromodulation, sacral neuromodulation, sacrectomy, sacrum

Sacral chordoma is a rare malignant tumor arising from remnants of the notochord. Due to its propensity for recurrence, the treatment of choice is surgical resection. Orthopedic and neurosurgical literature describe bladder dysfunction as prevalent in these patients, specifically urinary incontinence, however urologic literature is lacking in the exact nature of this dysfunction. Thus far, Sacral Nerve Stimulation (SNS) has not been described as a treatment option for these patients. We describe a 36-year-old female who underwent midsacral resection (S3 and below) for a sacrococcygeal chordoma. She suffered from postoperative urinary incontinence and incomplete emptying requiring intermittent catheterization. Urodynamic evaluation…

Tarantula toxin untangles pain pathways

A toxin isolated from the Togo starburst tarantula provides new insights into pain mechanisms and could lead to new treatments for irritable bowel syndrome. With their large, hairy bodies and long legs, tarantulas are an arachnophobe’s worst nightmare. For pain researchers, however, these outsized spiders are a dream come true: Their venom contains a cocktail of toxins, each of which activates pain-sensing nerve fibers in different ways, and researchers in the United States have now identified one such toxin that will help them to better understand pain, and could also lead to treatments for the chronic pain associated with irritable…
