Our objective is to study the relationship between armed conflict injuries and pain and the treatments that have been applied to Ukrainian injured soldiers in our hospital. ⋯ The study of injuries caused in current armed conflicts can help us anticipate complications and understand and treat pain early to improve the independence of patients, especially of amputee patients.

Focal nerve injuries are often associated with neuropathic pain. Preclinical research suggests altered neuroimmune signalling underlies such neuropathic pain; however, its cause remains poorly understood in humans. In this multicentre cohort study, we describe the local cellular and molecular signature of neuropathic pain at the lesion site, using Morton's neuroma as a human model system of neuropathic pain (n = 22; 18 women) compared with nerves from participants without nerve injury (n = 11; 4 women). ⋯ Targeted immunofluorescent analyses confirmed higher densities of intraneural CD163+MARCO+ macrophage subsets in Morton's neuroma. Our findings provide detailed insight into the local molecular signature in the context of human focal nerve injury. There is clear evidence for an ongoing role of the immune system in chronic peripheral neuropathic pain in humans, with macrophages and specifically the M(GC) MARCO+ subset implicated.

Postmastectomy pain syndrome (PMPS) is a chronic condition that significantly impacts breast cancer survivors, marked by persistent neuropathic pain that is often unresponsive to conventional therapies. Spinal cord stimulation (SCS) has emerged as a promising intervention for managing this type of pain. This study aimed to assess the clinical efficacy of SCS in managing PMPS and identify patient-specific factors impacting treatment outcomes. ⋯ SCS is an effective treatment for PMPS, with age, BMI, psychologic treatments, and prior radiotherapy being significant predictors of outcomes. Tailoring treatment plans to these factors can potentially enhance pain management for patients with PMPS.

Neuropathic pain involves neuroinflammation and upregulation of glycolysis in the central nervous system. Unfortunately, few effective treatments are available for managing this type of pain. The overactivation of lactate dehydrogenase A (LDHA), an essential enzyme in glycolysis, can cause neuroinflammation and nociception. This study investigated the spinal role of LDHA in neuropathic pain. ⋯ In conclusion, LDHA may be a potential therapeutic target for treating neuropathic pain by regulating neuroinflammation and angiogenesis.
