Randomized Controlled Trial
Modulation of mRNA expression of IL-6andmTORC1 and efficacy and feasibility of an integrated approach encompassing cognitive behavioral therapy along with Pregabalin for management of neuropathic pain in Postherpetic Neuralgia: A Pilot Study.
This study was designed to explore the efficacy and feasibility of cognitive behavioral therapy (CBT) along with pregabalin and compare it with pregabalin monotherapy for the management of neuropathic pain in post-herpetic neuralgia (PHN) patients and to explore the modulation of messenger RNA (mRNA) expression of interleukin (IL)-6 and mammalian target of rapamycin-1 (mTORC1) genes in these patients. ⋯ A significant downregulation of mRNA expression of IL-6 was observed; however, no significant correlation was observed between NRS pain score and ΔCt values of mRNA expression of both mTORC1 gene and IL-6 gene at baseline and at the end of 12th week. In addition, we note a significant decrease in pain intensity, depressive symptoms, and pain-related catastrophizing while improving QOL was observed with the use of CBT as a clinical adjunct along with pregabalin in PHN patients.

Randomized Controlled Trial
Efficacy and safety of EMA401 in peripheral neuropathic pain: results of two randomised, double-blind, phase 2 studies in patients with postherpetic neuralgia and painful diabetic neuropathy.
The analgesic efficacy and safety of 2 phase 2b studies of EMA401 (a highly selective angiotensin II type 2 receptor antagonist) in patients with postherpetic neuralgia (EMPHENE) and painful diabetic neuropathy (EMPADINE) were reported. These were multicentre, randomised, double-blind treatment studies conducted in participants with postherpetic neuralgia or type I/II diabetes mellitus with painful distal symmetrical sensorimotor neuropathy. Participants were randomised 1:1:1 to either placebo, EMA401 25 mg, or 100 mg twice daily (b.i.d) in the EMPHENE and 1:1 to placebo or EMA401 100 mg b.i.d. in the EMPADINE. ⋯ Out of the planned participants, a total of 129/360 (EMPHENE) and 137/400 (EMPADINE) participants were enrolled. The least square mean reduction in numeric rating scale pain score was numerically in favour of EMA401 100 mg arm in both EMPHENE (treatment difference: -0.5 [95% confidence interval: -1.6 to 0.6; P value: 0.35]) and EMPADINE (treatment difference: -0.6 [95% confidence interval: -1.4 to 0.1; P value: 0.10]) at the end of week 12. However, as the studies were terminated prematurely, no firm conclusion could be drawn but the consistent clinical improvement in pain intensity reduction across these 2 studies in 2 different populations is worth noting.

Since 2017, the diagnosis of patients with orofacial pain at the University Center for Dental Medicine Basel has been supplemented by using standardized image graphics (Dolografie® [Affolter/Rüfenacht, Bern, Switzerland]). For this purpose, patients select from a set of 34 cards those that visually best match their pain and then explain the reason for their choice. ⋯ The use of standardized image cards as a "visual communication tool" has proven to be a time-efficient procedure in the context of history taking, which helps to obtain clinically relevant information not previously expressed by the patient.

This study aimed to investigate the effects of popliteal sciatic nerve block (PSNB) in the treatment of postinjection sciatic neuropathy (PISN) resistant to conservative treatments. ⋯ The outcome of this research proved the effectiveness of PSNB with methylprednisolone in the management of PISN, especially in patients whose pain was located below the knee. EPSs findings and loss of muscle strength indicated the severity of the nerve damage affect the success of PSNB in pain management, but the length of time that elapsed after the nerve injury did not.
