Randomized Controlled Trial
Short-Term Supraorbital Nerve Stimulation and Pain Relief for Acute and Subacute Ophthalmic Herpetic Neuralgia: A Randomized Controlled Crossover Trial.
Herpes zoster ophthalmicus (HZO) is a kind of refractory disease, and treating it is important for preventing postherpetic neuralgia (PHN). But the evidence surrounding the current treatment options for these conditions is controversial, so exploring reasonable clinical treatment strategies for HZO is necessary. Neuromodulation is an excellent modality for the treatment of various neuropathic pain conditions. This trial was designed to evaluate the effectiveness of short-term supraorbital nerve stimulation (SNS) and the supraorbital nerve block (SNB) for HZO. ⋯ Short-term SNS is effective for controlling acute or subacute ophthalmic herpetic neuralgia. Combining SNS with SNB yields no additional benefits.

Randomized Controlled TrialVolumetric effect of shunt adjustments in normal pressure hydrocephalus: a randomized, double-blind trial.
MRI volumetry could be used as an alternative to invasive tests of shunt function. In this study, the authors aimed to assess the difference in ventricular volume (VV) before and after surgery and at different performance levels (PLs) of the shunt. ⋯ The consistent decrease in VV after shunt surgery and between PL 2.5 and 1.0 supports the idea that MRI volumetry could be a noninvasive method for evaluating shunt function in iNPH, preventing unnecessary shunt revisions. However, further studies on retest variability of VV as well as verification against advanced testing of shunt function are needed before a clinical implementation of this method can be performed. Clinical trial registration no.: NCT04599153 (ClinicalTrials.gov).

Randomized Controlled Trial
Effects of high-frequency hyperthermia on the elastic modulus of the lumbar muscle in female athletes with low back pain: A randomized crossover trial.
To investigate the effects of capacitive and resistive monopolar radiofrequency (CRMF) on the shear elastic modulus of the multifidus and erector spinae muscles in female athletes with low back pain (LBP) and a history of LBP. ⋯ CRMF can be used to reduce the shear elastic modulus of the multifidus muscle in the short term. Further studies are warranted to determine how to provide longer effects.

Randomized Controlled TrialEffect of a vapor barrier in combination with active external rewarming for cold-stressed patients in a prehospital setting: a randomized, crossover field study.
Use of a vapor barrier in the prehospital care of cold-stressed or hypothermic patients aims to reduce evaporative heat loss and accelerate rewarming. The application of a vapor barrier is recommended in various guidelines, along with both insulating and wind/waterproof layers and an active external rewarming device; however, evidence of its effect is limited. This study aimed to investigate the effect of using a vapor barrier as the inner layer in the recommended "burrito" model for wrapping hypothermic patients in the field. ⋯ The use of a vapor barrier as the innermost layer in combination with an active external heat source leads to higher mean skin rewarming rates in patients wearing wet clothing who are at risk of accidental hypothermia.

The past 20 years have seen a dramatic shift in our understanding of the role of the immune system in initiating and maintaining pain. Myeloid cells, including macrophages, dendritic cells, Langerhans cells, and mast cells, are increasingly implicated in bidirectional interactions with nerve fibres in rodent pain models. However, our understanding of the human setting is still poor. ⋯ The directionality of results between studies was inconsistent, although the clearest pattern was an increase in macrophage frequency across conditions, phases, and tissues. Myeloid cell definitions were often outdated and lacked correspondence with the stated cell types of interest; overreliance on morphology and traditional structural markers gave limited insight into the functional characteristics of investigated cells. We therefore critically reappraise the existing literature considering contemporary myeloid cell biology and advocate for the application of established and emerging high-dimensional proteomic and transcriptomic single-cell technologies to clarify the role of specific neuroimmune interactions in chronic pain.
