Chronic low back pain (CLBP) has become a worldwide health concern, and emotional distress is an important issue for CLBP management. However, it remains poorly understood how emotional distress happens and develops. This study aimed to systematically explore the correlates of emotional distress in patients with CLBP. ⋯ This study aimed to explored the correlates of emotional distress of patients with chronic low back pain (CLBP) by hierarchical linear regression analysis. The study found that patients' demographic factors, psycho-behavioral factors, and social support were associated with their emotional distress, uniquely explaining 16.5%, 18.4%, and 6.2% of the variance, respectively. Pain intensity, passive coping, active coping, self-efficacy, and social support were detected as significant correlates.

A better understanding of gender differences can assist clinicians in further developing therapeutic programs in tension type headache (TTH). ⋯ This study described gender differences in the presence of TrPs in TTH. Women with TTH showed lower PPTs than men. The association between TrPs, anxiety levels, and pressure pain hyperalgesia seems to be more pronounced in women than in men with TTH.

There have been no community-based studies investigating the association between sleep duration and postherpetic neuralgia (PHN) development. The aim of the current study was to examine the association of sleep with herpes zoster (HZ) incidence and PHN. ⋯ Sleep shortage was associated with increased risk for PHN, and hyperesthesia and acute pain intensity appeared to mediate this association. Sleep shortage may be a novel risk factor for PHN.

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.

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.
