Central poststroke pain (CPSP) is a neuropathic pain secondary to cerebrovascular accidents. This is characterized by pain and other sensory abnormalities, which correspond with the area of the injured brain. ⋯ We present 5 patients with CPSP, who were refractory to pharmacotherapy and were successfully managed with stellate ganglion blocks. A significant decrease in pain scores and improvement in functional disabilities were noted in all patients following the intervention.

Pain-depression comorbidity has become a great burden to individuals and society. Nevertheless, the mechanisms underlying comorbid diseases have still not been fully revealed. Ultrasound-guided pulsed radiofrequency (PRF) on peripheral nerves, which produces remarkable analgesia via high-frequency electromagnetic energy, has become a main, minimally invasive treatment for chronic neuropathic pain. ⋯ These findings suggest that ultrasound-guided PRF on sciatic nerve could alleviate pain-induced depression. The mechanisms of this treatment may be involved in the downregulated spinal IRF8 and the increased BDNF in PFC.

We aimed at investigating whether functional and morphometric tests assessing small-fibre damage, ie quantitative sensory testing, Sudoscan and skin biopsy, reliably reflect neuropathic pain and autonomic symptoms in patients with late-onset hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN). ⋯ Our findings indicate that functional test parameters reliably reflect neuropathic pain and autonomic symptoms related to small-fibre damage. These findings might help to identify clinically useful biomarkers to assess patient follow-up.

We investigated the efficacy and safety of twice-daily bilayer sustained-release tramadol hydrochloride tablets (35% immediate-release; 65% sustained-release) in patients with postherpetic neuralgia. ⋯ Sustained-release tramadol tablets with an immediate-release component are effective and well tolerated for managing postherpetic neuralgia.
