Management of Post-Stroke Cold Sensations: A Case Study on Sympathetic Nerve Ablation.

BACKGROUND Stroke is a leading cause of mortality worldwide and often results in complex sequelae. Peripheral circulation disorders in paralyzed limbs are particularly challenging, presenting as persistent cold sensations and cold-induced pain that severely impair patients' quality of life. This report presents an innovative approach to managing refractory post-stroke limb coldness and pain using computed tomography (CT)-guided sympathetic nerve radiofrequency ablation.

Single-cell immune profiling and validation of PBMCs in the onset of and recovery from herpes zoster.

To gain deeper insights into pathogenesis of herpes zoster, the peripheral blood mononuclear cells (PBMCs) from male patients mostly were subjected to single-cell RNA-seq (scRNA-seq) and ATAC-seq analysis. Here we show a detailed immune cell profile in the onset of and recovery from herpes zoster, revealing proportion alterations of the subpopulations, which were validated by flow cytometric analysis and comparison of blood routine data. The integrative analysis of the transcriptomes and epigenomes provided a comprehensive description and validation of the key changes in peripheral blood.

Risk Factors Affecting the Outcomes of CT-Guided Radiofrequency Thermocoagulation of the T3 Sympathetic Nerve in the Treatment of Craniofacial Hyperhidrosis.

Background: Current studies mostly suggest that hyperhidrosis is caused by relative sympathetic hyperactivity. Sympathetic radiofrequency thermocoagulation is widely used in clinics. Previous studies have demonstrated that surgery at T3 is effective and safe compared with higher levels, so craniofacial hyperhidrosis in our hospital is selected to be treated at T3.

Technique of Awake Computed Tomography-guided Percutaneous Balloon Compression of the Gasserian Ganglion for Trigeminal Neuralgia.

Background: The classic percutaneous balloon compression (PBC) technique is used to complete an operation under the guidance of C-arm radiography under general anesthesia, making communication with patients during the operation impossible. It is not accurate or objective to predict the classic technique's curative effect solely by determining whether the projection of the x-ray lateral image of the filled balloon is pear-shaped.

Objectives: This study aimed to upgrade classic PBC to awake computed tomography (CT)-guided PBC technology under conscious local anesthesia and analgesia monitoring.

Milk Fat Globule-EGF Factor 8 (MFGE8) Mitigates Cognitive Impairment in Rats with Sepsis-Associated Encephalopathy: An fMRI Study.

Background: Sepsis-associated encephalopathy (SAE) impairs hippocampal microglial efferocytosis, causing cognitive deficits. Previous research found that milk fat globule epidermal growth factor 8 protein (MFGE8) stimulates efferocytosis, reducing hippocampal inflammation in SAE rats. In this study, we explore MFGE8's role in alleviating cognitive impairment and its impact on neural activity using functional magnetic resonance imaging (fMRI).

Central post-stroke pain (CPSP) is a neuropathic pain syndrome that frequently occurs following cerebral stroke. The pathogenesis of CPSP is mainly due to thalamic injury caused by ischemia and hemorrhage. However, its underlying mechanism is far from clear.

Efficacy of Patient-Controlled Intravenous Analgesia with Esketamine for Herpes Zoster Associated with Breakthrough Pain.

Background: Some patients with herpes zoster (HZ) experience an intermittent spontaneous, short-lived and severe pain, which is called breakthrough pain (BTP). The effect of analgesic drugs and invasive procedures is not significant. Therefore, treatment of HZ associated with BTP is challenging.

Early Diagnosis of Herpes Zoster Neuralgia: A Narrative Review.

Background: Early intervention reduces the incidence of postherpetic neuralgia (PHN). Typical shingles are easy to diagnose; however, there is no clear diagnostic method for neuralgia symptoms manifested before the onset of the rash, which can easily cause misdiagnosis. This not only increases the patient's pain, medical expenses, and mental burden, but more importantly, delays the valuable time for early treatment of shingles, and increases the probability of complications and PHN.

Analysis of Risk Factors and Prediction Model for Recurrence of Hemifacial Spasm After Radiofrequency Ablation.

Background: Computed tomography (CT)-guided percutaneous stylomastoid foramen puncture radiofrequency ablation for the treatment of hemifacial spasm has a significant clinical effect; however, related risk factors for recurrence have not been studied.

Objective: To investigate the risk factors for the recurrence of hemifacial spasm after radiofrequency ablation and construct a model for predicting recurrence.

Study Design: This is a single-center retrospective observational study.

Effect of Repeated High-voltage Long-duration Pulsed Radiofrequency on Herpetic Neuralgia.

Background: Pulsed radiofrequency (PRF) is a commonly used, minimally invasive method to treat herpes zoster neuralgia, but the intensity of standard voltage PRF is limited, resulting in patients not getting a lasting therapeutic effect. The therapeutic effect of repeated high-voltage long-duration PRF on acute herpes zoster neuralgia has not been studied.

Objective: How to effectively reduce the incidence of postherpetic neuralgia is a serious challenge for clinicians.

Electroacupuncture Attenuates Cancer-Induced Bone Pain via NF-κB/CXCL12 Signaling in Midbrain Periaqueductal Gray.

Electroacupuncture (EA) is effective in various chronic pains. NF-κB and CXCL12 modulate the formation of chronic pain. Herein, we hypothesized that EA alleviates cancer-induced bone pain (CIBP) through NF-κB/CXCL12 axis in midbrain periaqueductal gray (PAG), which participates in "top-down" pain modulatory circuits.

Liquiritin Alleviates Pain Through Inhibiting CXCL1/CXCR2 Signaling Pathway in Bone Cancer Pain Rat.

Bone cancer pain (BCP) is an intractable clinical problem, and lacked effective drugs for treating it. Recent research showed that several chemokines in the spinal cord are involved in the pathogenesis of BCP. In this study, the antinociceptive effects of liquiritin, which is an active component extracted from Glycyrrhizae Radix, were tested and the underlying mechanisms targeting spinal dorsal horn (SDH) were investigated.

Samples from forty patients with herpes zoster neuralgia (HZN) (Group H), 40 patients with nonherpes zoster neuralgia (Group N), and 20 cases of health check-up were collected. Patients were divided into PHN group (Group A) and non-PHN group (Group B) according to the occurrence of PHN in Group H.

Personalized needle modification for CT-guided percutaneous infrazygomatic radiofrequency ablation of the maxillary nerve through the foramen rotundum in order to treat V2 trigeminal neuralgia.

The computed tomography (CT)-guided radiofrequency ablation (RFA) of the maxillary nerve (V2) via foramen rotundum (FR) approach has been reported to offer the highest rates of pain relief in V2 trigeminal neuralgia (TN). However, the access to FR may be obstructed by the greater wing of the sphenoid bone. We report on an optimized CT-guided percutaneous infrazygomatic of maxillary nerve through the foramen rotundum (FR) to treat V2 trigeminal neuralgia (TN) using personalized RFA needles based on patient's individual CT-image parameters.
