Review Meta Analysis
Influence of greater occipital nerve block on pain severity in migraine patients: A systematic review and meta-analysis.
Greater occipital nerve (GON) block may be a promising approach to treat migraine. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the efficacy of GON block in migraine patients. ⋯ Compared to control intervention, GON block intervention can significantly alleviate pain, reduce the number of headache days and medication consumption, but have no significant influence on the duration of headache per four weeks for migraine patients.

Case Reports
Transient vocal cord paralysis following central venous hemodialysis catheter insertion.
In this article, we present a case of recurrent laryngeal nerve palsy not caused by nerve injury but due to local anesthetic infiltration that was applied prior to central venous catheterization. A 47-year-old female patient was admitted to emergency room with fatigue and nausea and was diagnosed with acute renal failure. Right jugular venous catheterization was performed for emergency hemodialysis with Seldinger technique using middle approach. ⋯ We think temporary vocal cord palsy in our case was due to local anesthetic infiltration rather than nerve injury, since it resolved spontaneously within only hours. Expectant treatment is a good choice ensuring the patient's airway is safe. Emergency physicians should be aware of this rare complication and its right management.
