Sleep macrostructure is commonly disturbed after surgery. Postoperative pain control remains challenging. Given the bidirectional interaction between sleep and pain, understanding the role of modulation of sleep during the perioperative period on postoperative pain is needed. ⋯ Perioperative addition of a sleep-promoting pharmacological agent may improve pain control, but underlying evidence is weak and results are inconsistent. Only 5 of the 14 studies objectively evaluated changes in sleep (polysomnography, 2 zolpidem studies; actigraphy, 3 melatonin studies), which complicates conclusions regarding links between perioperative sleep and pain.

Dizziness is frequently reported in patients with migraine. However, its assessment is often neglected in clinical practice. We investigated the dizziness handicap experienced by patients with migraine and its contributing factors. ⋯ The data suggest that patients with migraine, especially those with chronic-type migraine, experience physical, emotional, and functional handicaps due to dizziness. Dizziness handicap is related to headache impact, anxiety, and depression. Targeted management of such factors is required to reduce the severity of subjective discomfort.

Review
Efficacy of Botulinum Toxin in Tension-Type Headaches: A Systematic Review of the Literature.
Botulinum toxin is approved to treat chronic migraine and has been shown to confer significant benefit in refractory cases. Due to its effect on pain by sensory modulation, there may also be efficacy in its use in chronic tension-type headache (CTTH). ⋯ This systematic review demonstrates variable study designs contributing to the low quality of evidence available regarding botulinum toxin in TTH, but some data suggest efficacy. There does not appear to be irrefutable evidence of a lack of efficacy of botulinum toxin in TTH. Using the paradigm for botulinum toxin in chronic migraine may prove fruitful in treating CTTH. Further studies are warranted to evaluate the utility of botulinum toxin in this common debilitating condition.

Randomized Controlled Trial
Ultrasound-Guided Cervical Nerve Root Block for the Treatment of Acute Cervical Herpes Zoster: A Randomized Controlled Clinical Study.
To evaluate the efficacy and safety of ultrasound-guided cervical nerve root block (CRB) on acute pain and its preventive effects on post-herpetic neuralgia (PHN) in patients with cervical herpes zoster (HZ). ⋯ Ultrasound-guided CRB represented an early intervention and preventive strategy to reduce the BOI due to acute HZ in the cervical dermatome region, and might be feasible to reduce the incidence of PHN.
