Neuropathic pain (NP) is often accompanied by psychiatric comorbidities and currently lacks effective treatment. Prior research has shown that HDAC6 plays a crucial role in pain sensitization, but the specific mechanisms remain unclear. HDAC6 inhibitors have been found to alleviate mechanical allodynia caused by inflammation and peripheral nerve damage. ⋯ ACY-1215 also inhibited neuron activation and suppressed CCI-induced pyroptosis and neuroinflammatory responses. In summary, our results suggest that HDAC6 contributes to the development and maintenance of NP through neuronal activation and neuroinflammation. HDAC6 may be a promising target for treating NP.

Case ReportsChallenging Pain Management in a Patient with Trigeminal Neuralgia Secondary to Multiple Sclerosis.
Patients suffering from multiple sclerosis (MS) often develop neuropathic pain. Trigeminal neuralgia (TN) is the most common type in these patients. The pain is characterised by recurrent, unilateral, brief, electric shock-like episodes, abrupt in onset and termination, and limited to the distribution of one or more divisions of the trigeminal nerve, which is difficult to treat when compared to classical TN. ⋯ However, due to severe side effects she had to quit its use. The patient was then successfully treated with an intravenous infusion of lidocaine and remained pain-free without any other pain medications. Key Words: Trigeminal neuralgia, Multiple sclerosis, Lidocaine.

Neuropathic pain (NP) is a type of chronic pain usually caused by damage to the somatosensory system. Bioactive antioxidant compounds, such as curcumin and ginger, are widely preferred in the treatment of NP. However, the ingredient-based mechanism that underlies their pain-relieving activity remains unknown. The aim of this study was to investigate the therapeutic effects of trans-[6]-Shogaol and [6]-Gingerol active ingredients of the Zingiber officinale Roscoe extract on the spinal cord and cortex in the neuroinflammatory pathway in rats with experimental sciatic nerve injury. ⋯ In this study, ginger treatment was shown to have a therapeutic effect on neuroinflammation against sciatic nerve damage.

In the early phase of the COVID pandemic 2020, we demonstrated how patients with painful polyneuropathy, against our expectations, did not experience a deterioration of their neuropathic pain. We hypothesized that our assessed measures, that is, pain intensity and characteristics, emotional wellbeing, and everyday life, would deteriorate in the further course of the pandemic according to the phases of disaster management. Thus, the aim of our study was to investigate patients repeatedly under varying pandemic conditions from March until December 2020. ⋯ The perception of pain intensity was dependent on pandemic severity. Sleep, mood, and quality of life did not change significantly in validated measures. Continued medical care seems decisive to prevent worsening of pain and quality of life.

Randomized Controlled Trial
Randomized active-controlled study of a single preoperative administration of duloxetine to treat postoperative pain and numbness after posterior lumbar interbody fusion surgery.
This prospective, randomized, double-blinded, active controlled trial assessed whether a single preoperative administration of 40 mg of duloxetine could decrease postoperative pain and numbness after posterior lumbar interbody fusion surgery (PLIF). ⋯ A single preoperative 40-mg dose of duloxetine did not improve postoperative pain after PLIF, but did improve lower limb numbness. Duloxetine may suppress neuropathic pain-like symptoms after PLIF surgery.
