The symptom severity of back pain/leg pain is not correlated with the severity of degenerative changes and canal stenosis in lumbar stenosis. Considering the individual pain sensitivity might play an important role in pain perception, this discordance between the radiologic findings and clinical symptoms in degenerative lumbar stenosis might originate from the individual difference of pain sensitivity for back pain and/or leg pain. ⋯ The current study suggests that the pain sensitivity could be a determining factor for symptom severity in the degenerative spinal disease.

Clinical Trial
Intravesical botulinum toxin a injections do not benefit patients with ulcer type interstitial cystitis.
Ulcer type and non-ulcer type interstitial cystitis/bladder pain syndromes (IC/BPS) are considered different disease entities. Thus, intravesical botulinum toxin A (BoNT-A) treatment outcomes could differ for each entity. ⋯ Repeated intravesical BoNT-A injections provided effective treatment outcomes at the end-point in half of the patients with non-ulcer IC/BPS, but did not benefit any patient with ulcer type IC/BPS. Ulcer type IC/BPS should be treated as a different disease than non-ulcer IC/BPS. INSTITUTIONAL REVIEW: This study was approved by the Institutional Review Board of the Tzu-chi General Hospital (TCGH 100-06).

Pancreatic cancer pain is often severe and refractory to conservative therapies. Several interventional techniques have been described for the management of end-stage pancreatic cancer pain, with variable results and complications. ⋯ Radiofrequency thermocoagulation of both splanchnic nerves may offer a safe and effective technique for pain management and quality of life improvement in patients with end-stage pancreatic cancer towards the end of life.

Placement of an intrathecal drug delivery system (IDDS) may provide substantial benefit to certain patients. However, placement of these devices is not without complications, and minimal data exist describing the rates of these complications. Specifically, there is a paucity of data describing the incidence of post dural puncture headache (PDPH) following IDDS placement. ⋯ Though the development of PDPH after IDDS implantation was found to be fairly common (23% incidence), the majority of these patients had self-limited symptoms that resolved with conservative medical management. Epidural blood patch or application of epidural fibrin glue was therapeutically successful for the remainder of PDPH patients who were refractory to conservative measures.

Pain is influenced by weather changes under certain circumstances, and inflammatory pain in animal models is ameliorated by pressure, but the underlying mechanism of atmospheric pressure has not been clearly elucidated. ⋯ Exposure to elevated pressures appears to relieve arthritic pain for extended periods by reducing the inflammatory process and should be considered as a possible alternative pain-reducing therapy.
