Uncommon stimulation refers to the use of peripheral nerve and spinal cord stimulation for nontraditional applications. There has been much interest recently with subcutaneous suboccipital stimulation for occipital neuralgia, sacral stimulation for pelvic pain, trigeminal stimulation for trigeminal neuralgia, and spinal cord stimulation for angina and peripheral ischemia. The indications and techniques used for accomplishing each method are discussed.

Sex-related differences in the experience of both clinical and experimentally induced pain have been widely reported. Specifically, females are at greater risk for developing several chronic pain disorders, and women exhibit greater sensitivity to noxious stimuli in the laboratory compared with men. Several mechanisms have been proposed to account for these sex differences. ⋯ Sex hormones are also known to affect pain responses, which may mediate the sex differences. Although the magnitude of these effects has not been well characterized, there are potentially important practical implications of sex differences in pain responses. These implications are discussed, and directions for future research are delineated.

Comparative Study Clinical Trial Controlled Clinical TrialThe diagnostic validity and therapeutic value of lumbar facet joint nerve blocks with or without adjuvant agents.
Facet joints have been described as an important source of low back pain. The value of medial branch blocks in the diagnosis of facet joint mediated pain is considered important. However, the therapeutic value of medial branch blocks has not been determined. ⋯ Group I was treated with local anesthetic only, Group II with the addition of Sarapin, and Group III with the addition of Depo-medrol along with Sarapin. The prevalence of facet joint pain in chronic low back pain was determined as 36%, with a false-positive rate of 25%. Comparison of duration of relief in days with each block in the three groups showed that the relief was significantly superior in Group III compared with Group I and Group II, whereas Group II was superior to Group I.

Pain is one of the cardinal presenting symptoms in cancer patients and often seems to progress in the natural history of the disease. In light of the past neglect of this problem, it is becoming crucial for clinicians and researchers in the fields of oncology, pain management, and others dealing with this patient population to have a thorough understanding of the often complex pain syndromes that are relevant to managing cancer. In this article we briefly review the important topics related to cancer pain syndromes with some emphasis on those that typically generate localized pain.

Postherpetic neuralgia (PHN) is the most common complication of herpes zoster, and as such has been an area of extensive medical research for the past three decades. The patients at highest risk for PHN include those older than 50 years, those with severe acute cases of zoster, and those with shingles in a trigeminal distribution. As persons with malignancy are at a high risk for developing zoster itself, PHN is a complication that will be faced by many of these patients and their caregivers. This article reviews the available treatments and preventative measures for this debilitating condition.
