The objective was to present new visual sensorimotor findings in a patient with complex regional pain syndrome type I, formerly known as reflex sympathetic dystrophy. ⋯ The patient manifested signs and symptoms of complex regional pain syndrome type I per the prior neurologic diagnosis, as well as the newly diagnosed accommodative infacility, accommodative insufficiency, convergence insufficiency, and deficits of saccades and pursuits, which were severely debilitating. The findings neither support nor refute the conventional notion of abnormal sympathetic mediation as a mechanism of fatigue and pain. However, the diagnoses of accommodative infacility and insufficiency suggest abnormal parasympathetic activation. Further investigation is needed to characterize the array of visual dysfunctions in a large sample of such patients, which may help elucidate the precise underlying neurologic causes of the sensorimotor deficits in these patients.

To determine the long-term efficacy of gabapentin as a treatment of pain after spinal cord injury. ⋯ Gabapentin may be an effective treatment of pain after spinal cord injury among those able to tolerate initial and long-term side effects.

Many juveniles with chronic pain of no known organic cause recover. Because adolescents whose pain persists may have chronic pain as adults, a subsample of 42 adolescents from a prevalence study in which continuation of their pain was observed throughout the study period was investigated quantitatively and qualitatively. All mothers (n = 42) completed a questionnaire on the impact of the adolescent's pain on the family. The authors tested the hypothesis that pain parameters, pain-related quality of life, and impact of pain on the family would deteriorate over time. ⋯ For adolescents with persistent pain with no known organic cause, intensity and frequency of pain, quality of life, and impact of pain on the family did not change. Generally, they seemed to cope quite well with their pain. In view of these results, further studies should involve follow-up of adolescents with persistent pain into adulthood to establish the determinants of their pain and to find out whether they maintain their adaptive ways of living with their pain.

The objective was to examine the evidence to determine the optimal management of phantom limb pain in the preoperative and postoperative phase of amputations. ⋯ Although up to 70% of patients have phantom limb pain after amputation, there is little evidence from randomized trials to guide clinicians with treatment. Evidence on preemptive epidurals, early regional nerve blocks, and mechanical vibratory stimulation provides inconsistent support for these treatments. There is currently a gap between research and practice in the area of phantom limb pain.

The case here presented adequately reflects the difficulties involved in the treatment of pain in patients where the neuropathic component of pain predominates, and shows the different therapeutic steps that may be taken-from surgery and radiotherapy, to the administration of different drugs via the spinal route, to, finally, the presently little-used option of a direct intraventricular access. ⋯ Spinal tumors are infrequent, but pose great difficulties for the management and control of the pain they cause. The utility of the spinal route as an early approach for the provision of adequate analgesia seems clear. However, it also appears to lose efficacy with time, and dose incrementing and/or the addition of drugs that enhance the analgesic action of morphine are not always effective. In such selected cases, the intraventricular route may constitute a useful alternative, allowing improved symptoms control with lower morphine doses, and the use of the system previously implanted for intrathecal spinal infusion.
