Herpes zoster (HZ) is caused by the reactivation of varicella zoster virus. The incidence of herpes zoster and associated problems increases with age. With a life-long prevalence of 30%, every second 85-year-old person experiences HZ once in his lifetime. ⋯ HZ vaccination represents a substantial improvement in terms of prevention of herpes zoster and reduction of long-term complications, such as PHN. The permanent vaccination commission of the Robert Koch Institute recommends vaccination with dead virus for all persons over the age of 60 years. Risk groups like immunosuppressed patients are advised to be vaccinated starting at the age of 50 years.

Neuropathic pain, a type of chronic pain as a result of direct central or peripheral nerve damage, is associated with significant quality of life and functional impairment. Its underlying mechanisms remain unclear. We investigated whether ROR2, a member of the receptor tyrosine kinase-like orphan receptor (ROR) family, participates in modulation of neuropathic pain. ⋯ ROR2 in the spinal cord regulates neuropathic pain via phosphorylation of GluN2B, suggesting a potential target for prevention and relief of neuropathic pain.

Neuropathic pain (NeP) is often under-recognized, resulting in poor pain management. Therefore, a Taiwan version of the 10-item Douleur Neuropathique 4 (DN4-T) questionnaire was developed to identify patients with NeP from a mixed population of patients with pain. ⋯ The DN4-T questionnaire has been reliably translated into Mandarin Chinese and can be used as a diagnostic tool for NeP in conjunction with clinical evaluation.

The chronic neuropathic pain-associated psychiatric disorders have seriously disturbed the quality of patients' life, such as depression and anxiety. Neuroinflammation in the hippocampus plays an important role in the neuropathic pain-associated depressive and anxiety disorders, but the underlying mechanism has not been thoroughly elucidated to date. The Nod-like receptor protein (NLRP)-1 inflammasome, which controls the production of pro-inflammatory cytokines, was broadly involved in the neuroinflammation-related diseases. ⋯ Functional inhibition of PKR suppressed the NLRP1 inflammasome activation and effectively attenuated the CCI-induced depression-like behaviors. These results indicate that the hippocampal PKR/NLRP1 inflammasome pathway play an important role in the development of the depressive behaviors after chronic neuropathic pain. Thus, interrupting this pathway might provide a novel therapeutic strategy for neuropathic pain-associated depressive disorders.
