Percutaneous radiofrequency neurotomy has been used in the treatment of pain from the cervical zygapophysial joints, but the results have been modest and not compelling. Several factors might account for its apparent poor success rate, including inadequate patient selection, inaccurate surgical anatomy, and technical errors. In an effort to overcome these confounders, we used comparative local anesthetic blocks to preoperatively, definitively diagnose cervical zygapophysial joint pain and developed an amended operative technique based on formal anatomical studies. ⋯ After procedures at all levels, a brief period of postoperative pain was experienced by the patients and ataxia was a side effect of third occipital neurotomy. There were no cases of postoperative infection or anesthesia dolorosa. Given the high technical failure rate of third occipital neurotomy, we recommend that this procedure be abandoned until the technical problems can be overcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment of occipital neuralgia by partial posterior rhizotomy at C1-3.
To minimize the sensory loss associated with intradural posterior rhizotomy for medically refractory occipital neuralgia, partial sectioning of the upper cervical posterior rootlets was performed in 11 patients. The ventrolateral aspect of each posterior rootlet from C-1 to the upper portion of C-3 was divided at the root entry zone. In three patients with bilateral neuralgia, the procedure was performed on both sides, for a total of 14 partial rhizotomy procedures in the 11 patients. ⋯ The other four procedures alleviated pain in the territory of the greater occipital nerve, but the results were marred by persistent periorbital or temporal pain. Two patients subsequently underwent complete C1-3 posterior rhizotomy without further improvement. Although partial posterior rhizotomy at C1-3 did not always relieve pain in the periorbital and temporal regions, this procedure did provide consistent long-term relief of severe occipital pain with minimal risk of postoperative vertigo, scalp anesthesia, or deafferentation syndrome.

Adjuvant analgesics are drugs that are not primarily used as analgesics but can produce analgesia in certain types of pain. Adjuvant analgesics can be administered together with non-opioid and opioid analgesics on each step of the WHO analgesic ladder. They should be given when an additional or specific indication exists, but should not be used as a substitute for a thorough treatment with opioids and nonopioids. ⋯ Biphosphonates (etidronate, clodronate, pamidronate derivates) also produce analgesic effects in patients with bone metastases. However, differences among the various compounds have not been clearly evaluated yet. Potent and specific radioisotopes are still under development and the use of calcitonin in bone pain is considered controversial.

Comparative Study
Patients' experiences of herpes zoster and postherpetic neuralgia.
The purpose of the study was to investigate retrospectively whether patients (n = 73) who had suffered another disease and/or experienced psychosocial stress at the time of the onset of herpes zoster had experienced a more severe clinical course of herpes zoster, and were more subject to the development of postherpetic neuralgia than other patients (n = 45) with herpes zoster. The interview questionnaire included questions about changes in the patients' daily lives due to neuralgia, and their current living circumstances. ⋯ More of these patients reported that their habits and activities had been negatively affected and they also experienced their current situation as unsatisfactory. These results must, however, be interpreted with caution as the patients' recollection of other diseases and/or psychosocial stress and the patients' current mood due to postherpetic neuralgia at the time of the interview may have influenced the memory and the answers.
