Trigeminal herpes zoster, which comprises 10% to 20% of cases of herpes zoster, often leads to severe pain in the ophthalmic branches. Current treatments, including drug therapy and minimally invasive interventions, have limitations; accordingly, there is a need to explore alternative approaches. This study aimed to evaluate the efficacy and safety of computerized tomography (CT)-guided pulsed radiofrequency of the sphenopalatine ganglion in patients with intractable trigeminal herpetic pain. ⋯ Our findings indicated that CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion was a safe and effective intervention for pain in patients with trigeminal ophthalmic zoster neuralgia, suggesting that it may be a therapeutic option if other treatments fail.

In males but not in females, brain derived neurotrophic factor (BDNF) plays an obligatory role in the onset and maintenance of neuropathic pain. Afferent terminals of injured peripheral nerves release colony stimulating factor (CSF-1) and other mediators into the dorsal horn. These transform the phenotype of dorsal horn microglia such that they express P2X4 purinoceptors. ⋯ Possible mechanisms promoting the preferential release of BDNF in pain signaling structures are discussed. In females, invading T-lymphocytes increase dorsal horn excitability but it remains to be determined whether similar processes operate in supra-spinal structures. Despite its ubiquitous role in pain aetiology neither BDNF nor TrkB receptors represent potential therapeutic targets.

Randomized Controlled Trial
Thoracic paravertebral nerve block combined with acupuncture for the treatment of postherpetic neuralgia in the chest and abdomen: A prospective randomized controlled trial.
Postherpetic neuralgia (PHN) is the most common complication of varicella-zoster infection and tends to occur in older people. All patients treated with a single regimen have not achieved consistent success across all current study protocols, and multimodal combination regimens still need to be explored. ⋯ Based on drug treatment combined with thoracic paravertebral nerve block and acupuncture, the treatment of PHN in the elderly can quickly and effectively relieve pain, improve the quality of life of patients, and improve the quality of sleep.

Observational Study
The long-term incidence of chronic post-surgical pain after coronary artery bypass surgery - A prospective observational study.
Chronic post-surgical pain (CPSP) represents a significant issue for many patients following surgery; however, the long-term incidence and impact have not been well described following cardiac surgery. Our aim was to characterize CPSP at least 5 years following coronary artery bypass grafting (CABG) surgery. ⋯ This study highlights the impact of CPSP 7 years following cardiac surgery and highlights the effect of surgical site, neuropathic pain and the importance of including pain assessment and management in the long-term follow-up of cardiac surgical patients. Strategies to address and prevent chronic pain following cardiac surgery should be further explored.

Association between smoking and central sensitization pain: a web-based cross-sectional study.
This study aimed to investigate whether smoking is an independent risk factor for central sensitization syndrome (CSS) in individuals with pain as measured by the Central Sensitization Inventory (CSI). ⋯ Smoking is an independent risk factor for CSS. This indicates that smoking may be an important factor in the management of central pain disorders.
