Comparative Study
Musculoskeletal Ultrasonography in CRPS: Assessment of Muscles Before and After Motor Function Recovery with Dry Needling as the Sole Treatment.
Motor impairment is an important criterion in the Clinical Diagnostic Criteria (CDC) of Complex Regional Pain Syndrome type-1 (CRPS-1) as defined by International Association for Study of Pain (IASP). ⋯ Myofascial pathology of co-contraction appears to cause CDC of CRPS and probable ischemic loss of myoarchitecture. Relief of co-contraction with USGDN allowed resolution of tenosynovitis causing the CDC and return of normal myoarchitecture.

Observational Study
The Extent of Tissue Damage in the Epidural Space by Ho / YAG Laser During Epiduroscopic Laser Neural Decompression.
Lasers have recently become very useful for epiduroscopy. As the use of lasers increases, the potential for unwanted complications with direct application of laser energy to nerve tissue has also increased. Even using the lowest laser power to test for nerve stimulation, there are still risks of laser ablation. However, there are no studies investigating tissue damage from laser procedures in the epidural space. ⋯ Even with low power and short duration, a laser can destroy tissue if the laser beam makes direct contact with the tissue.

Multicenter Study
Subjective Cognitive Symptoms During a Migraine Attack: A Prospective Study of a Clinic-Based Sample.
A migraine attack aggregates a range of different symptoms, besides pain, that contribute to attack-related disability. Cognitive dysfunction is an unacknowledged part of the migraine attack. ⋯ This study detailed the frequency and characteristics of migraine attack-related subjective cognitive symptoms and found its frequency to be similar to reports of other migraine defining symptoms (ex. nausea, photophobia) in recent clinical series. Patients' reports were consistent and dominated by complaints of attention difficulties, diminished cognitive efficiency, and processing speed impairment.

Meta Analysis
Effects of Intravenous and Oral Magnesium on Reducing Migraine: A Meta-analysis of Randomized Controlled Trials.
Migraine attack has been associated with magnesium deficiency. Previous studies investigating the effect of intravenous and oral magnesium on acute migraine attacks and the prevention of migraine have produced equivocal findings. ⋯ Intravenous magnesium reduces acute migraine attacks within 15 - 45 minutes, 120 minutes, and 24 hours after the initial infusion and oral magnesium alleviates the frequency and intensity of migraine. Intravenous and oral magnesium should be adapted as parts of multimodal approach to reduce migraine.

Randomized Controlled Trial
Minimum Effective Concentration of Bupivacaine in Ultrasound-Guided Femoral Nerve Block after Arthroscopic Knee Meniscectomy: A Randomized, Double-Blind, Controlled Trial.
Adequate analgesia is important for early hospital discharge after meniscectomy. A femoral nerve block may reduce the need for systemic analgesics, with fewer side effects; however, motor block can occur. Ultrasound-guided femoral nerve block may reduce the required local anesthetic concentration, preventing motor block. ⋯ Bupivacaine EC50 for ultrasound-guided femoral nerve block was 0.160 (95% CI: 0.150 - 0.189), and EC90 was 0.271 (95% CI: 0.196 - 0.300).
