Randomized Controlled Trial
Randomized pragmatic pilot trial comparing perpendicular thin electrodes versus parallel thick electrodes approaches for lumbar medial branch neurotomy in facetogenic low back pain.
Although there are different ways of performing medial branch neurotomy on facetogenic low back pain, few studies have compared clinical outcomes of a parallel technique over the medial branch vs. a perpendicular technique. We investigated differences in pain outcome with both techniques. ⋯ There were differences at 6 months in the categorical analysis of the evolution of pain, Oswestry Disability Index score, Roland Morris Questionnaire score, and some functional Likert scale scores, all in favor of the parallel group.

Randomized Controlled Trial
Local Administration of Methylcobalamin for Subacute Ophthalmic Herpetic Neuralgia: A Randomized, Phase III Clinical Trial.
The ophthalmic branch of the trigeminal nerve is one of the most frequently involved sites of postherpetic neuralgia. A single-center randomized controlled study was conducted to evaluate the efficacy of local methylcobalamin injection for subacute ophthalmic herpetic neuralgia (SOHN). ⋯ This study indicates that local injection of methylcobalamin produces significant pain relief from SOHN and is superior to systemic administration.
