Mpox outbreak among men who have sex with men in Kraków, Poland; June 2022-November 2022.
Mpox is a zoonotic disease caused by mpox virus. Sporadic cases reported before 2022 were almost universally linked to a direct contact with animals or travel to endemic regions of Africa. However, in 2022, a significant shift occurred in human‑to‑human transmission, leading to a global outbreak in 117 countries. In Poland, 217 cases of mpox were reported. ⋯ The 2022 mpox outbreak in Kraków primarily affected MSM and was transmitted through sexual contact. Health care professionals should be aware of emerging STIs. Educational initiatives should emphasize the importance of vaccinations, safe sexual practices, and regular testing.

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.
