Randomized Controlled Trial
Reduction in Migraine and Headache Frequency and Intensity with Combined Antioxidant Prophylaxis (N-acetylcysteine, Vitamin E and Vitamin C: NEC): A Randomized Sham-Controlled Pilot Study.
To investigate the preventive effects of a combined antioxidant drug (N-acetylcysteine, vitamin E, and vitamin C [NEC]) on migraine outcomes. Migraine is characterized by increased oxidative stress and neurogenic inflammation in the brain; therefore, antioxidants may have a migraine preventive effect. ⋯ This is the first randomized controlled trial to find that combined antioxidant therapy with NEC reduces headaches and migraines in adult migraineurs. Given the limitations of this pilot study, an adequately powered randomized controlled trial is planned to further investigate antioxidant prophylaxis in migraine.

Numerous mechanical and pathologic variables contribute to sacroiliac joint (SIJ) pain. The oncologic population has additional considerations, including tumor burden causing fracture, nerve compression, joint instability, and periosteal inflammation. Post-treatment changes may also restrict joint mobility, causing transitional pain. Currently, fluoroscopically guided SIJ injections, aimed at the inferior one third of the SIJ, are the gold standard for treatment but have only been described in the nononcologic population. Ultrasound (US) guidance may confer several benefits, including positioning, ease of procedure, lower costs, and, importantly, guidance to avoid neovascularization, metastatic disease, and other soft tissue structures. ⋯ We propose a decision framework for inferior vs. superior approach US-guided SIJ injections in the oncologic population with SIJ pain from metastases to the pelvis or sacrum. Having multiple techniques to approach the SIJ is important in the oncologic population, in whom metastatic tumor burden poses a technical challenge to performing these injections.
