Randomized Controlled Trial
Effect of early stellate ganglion blockade for facial pain from acute herpes zoster and incidence of postherpetic neuralgia.
The incidence of postherpetic neuralgia (PHN) has been reported to be 25% among those over the age of 50 years treated with antiviral medication. The role of sympathetic block in its prevention remains questionable. ⋯ Early stellate ganglion blockade, in combination with an antiviral agent, is a very effective treatment modality; it dramatically decreases the intensity of acute pain and shortens its duration and reduces the incidence of postherpetic neuralgia.

The effect of Helicobacter pylori eradication on migraine: a randomized, double blind, controlled trial.
Recent studies have shown a positive correlation between Helicobacter pylori (H. pylori)infection and migraine headache. ⋯ H. pylori eradication may have a beneficial role on migraine headache. This shows the significance of H. pylori treatment in the management of migraine headache among Iranian patients.

Randomized Controlled Trial
Central adaptation of pain perception in response to rehabilitation of musculoskeletal pain: randomized controlled trial.
Understanding the mechanisms of long-standing musculoskeletal pain and adaptations in response to physical rehabilitation is important for developing optimal treatment strategies. The influence of central adaptations of pain perception in response to rehabilitation of musculoskeletal pain remains unclear. ⋯ Examiner-blinded, parallel-group randomized controlled trial with allocation concealment.

Randomized Controlled Trial
Results of 2-year follow-up of a randomized, double-blind, controlled trial of fluoroscopic caudal epidural injections in central spinal stenosis.
Lumbar spinal stenosis is one of the most common causes of low back pain among older adults and can cause significant disability. Despite its prevalence, there is a paucity of literature concerning the treatment of spinal stenosis symptoms. Multiple interventions, including surgery and interventional techniques such as epidural injections and adhesiolysis, are commonly utilized in managing pain related to central spinal stenosis. However, there is a paucity of literature from randomized, controlled trials about the effectiveness of epidural injections for lumbar central spinal stenosis. ⋯ Caudal epidural injections of local anesthetic with or without steroids provide relief in a modest proportion of patients undergoing the treatment and may be considered as an effective treatment for a select group of patients who have chronic function-limiting low back and lower extremity pain secondary to central spinal stenosis.

Unreliability of the visual analog scale in experimental pain assessment: a sensitivity and evoked potentials study.
Pain is a universal but subjective experience, making it difficult to obtain objective information about the experiential dimensions of pain. Although the visual analog scale (VAS) is ubiquitously used in pain assessment, its reliability has been questioned. The properties of this rating scale, especially its anchor points likely to be reinterpreted by subjects, may bias the results. ⋯ Taken together, our psychophysical and SEP results suggest that healthy individuals reinterpret the "no pain" anchor on the classical pain-VAS commonly used in the experimental assessment of pain, by rating the intensity of the stimulation rather than pain perception.
