Transcranial direct current stimulation efficacy in trigeminal neuralgia

Trigeminal neuralgia is a severe,disabling pain and its deafferentation remains a challenge for health providers.Transcranial direct current stimulation is a non-invasive stimulation technique which finds new utility in managing pain.There-fore,the introduction of alternative,non-invasive,safe,and effective methods should be considered in treating patients with trigeminal neuralgia unresponsive to conventional treatment.

Meta-analysis and sequential analysis of acupuncture compared to carbamazepine in the treatment of trigeminal neuralgia

BACKGROUND In this randomized controlled trial(RCT)comparing current acupuncture with carbamazepine for trigeminal neuralgia,meta-and sequential analyses were utilized.AIM To guide clinical decision making regarding the treatment of trigeminal neuralgia with carbamazepine.METHODS The RCT literature on needle comparison was searched in various Chinese biomedical databases including Chinese Biomedical Literature Database,Wanfang Data,VIP Database,as well as international databases such as Excerpt Medica Database,Cochrane Library,PubMed,and Web of Science,along with related clinical registration platforms such as World Health Organization International Clinical Trial Registry Platform,ChiCTR,and Clinical Trials up to 1 April 2020.Risk of bias was evaluated using the Cochrane Collaborative Risk Bias tool,primary outcome measures(pain reduction)were analyzed using STATA metaanalysis,outcome measures were analyzed using trial sequential analysis 0.9.5.10 Beta sequential analysis,GRADE was used to assess the evidence,and adverse reactions were documented.RESULTS This study analyzed 16 RCTs with a total of 1231 participants.The meta-analysis revealed a statistically significant difference in pain reduction between acupuncture and carbamazepine[standardized mean difference(SMD)=1.47;95%confidence interval(CI):0.99-1.95],although the quality of evidence was deemed to be of extremely low quality.Cumulative meta-analysis based on the year of publication indicated that carbamazepine treatment first demonstrated a statistically significant difference in pain reduction in 2014 and remained relatively stable over time[SMD=1.84;95%CI:0.22-3.47].Additionally,the number of adverse events associated with acupuncture was significantly lower compared to carbamazepine.CONCLUSION Acupuncture for trigeminal neuralgia is better than analgesia and safer than carbamazepine;however,firm conclusions still require a high-quality,multicenter,large-sample RCT to confirm these findings.

Laser speckle contrast imaging to predict the effect of temporary spinal cord stimulation in postherpetic neuralgia patients: A prospective observational study

Temporary spinal cord stimulation(tSCS)can effectively reduce the pain and severity of postherpetic neuralgia(PHN).However,there are no effective and objective methods for predicting the effects of tSCS on PHN.Laser speckle contrast imaging(LSCI)is frequently used in neurology to evaluate the effectiveness of treatment.To assess the accuracy of LSCI in predicting the impact of tSCS on PHN,14 adult patients receiving tSCS treatments for spinal nerve-innervated(C6-T2)PHN participated in this observational study.Visual analog scale(VAS)assessments and LSCI bloodflow images of the-ngers were recorded after the tSCS procedure.The results showed that the VAS scores of all patients decreased signi-cantly.Moreover,the bloodflow index(BFI)values were signi-cantly higher than they were before the procedure.Increased bloodflow and pain alleviation were positively correlated.The-ndings indicated that spinal nerve PHN(C6-T2)was signi-cantly reduced by tSCS.Pain alleviation by tSCS was positively correlated with increased bloodflow in the hand.The effect of tSCS on PHN may thus be predicted using an independent and consistent indicator such as LSCI.

Mechanism of Huanglian Detoxification Soup Relieving Postherpetic Neuralgia by Enhancing IL-2 Levels in Rats

[Objectives]To explore the mechanism of Huanglian detoxification soup improving pain behavior by affecting serum IL-2 levels in postherpetic neuralgia(post herpes neuralgia,PHN)model rats.[Methods]20 PHN rats were randomly divided into model group(PHN group)and detoxification decoction group(n=10).In the group,10%Huanglian detoxification soup(0.4 mL/0.1 kg)was given once in the morning and evening for 14 d.The PHN group was filled with an equal volume of 0.9%sodium chloride solution.Tail vein serum inflammatory factor interleukin-2(IL-2),IL-βand IL-6 levels were measured using ELISA kits at 7 and 21 d.[Results]IL-2 increased at 14 and 21 d in IL group,while IL-βand IL-6 decreased compared with the PHN group(P<0.05).[Conclusions]Huanglian detoxification soup may raise IL-2 levels after VZV infection to promote the differentiation of cells of the immune system,so as to relieve the pain caused by IL-βand IL-6 inflammatory factors.

Analysis of the Degree of Psychological Distress of Elderly Patients with Recurrent Trigeminal Neuralgia and Its Influencing Factors

Objective:To analyze the degree of psychological distress among elderly patients with recurrent trigeminal neuralgia and its influencing factors.Methods:A single-center cross-sectional study was conducted on 126 elderly patients with recurrent trigeminal neuralgia who visited the Pain Department of our hospital from March 2022 to April 2024.Logistic regression analysis was employed to evaluate the factors influencing psychological distress,based on general patient data,the Distress Thermometer(DT),the Perceived Social Support from Family Scale(PSS-Fa),and the Pitsburgh Sleep Quality Index(PSQI).Results:Among the 126 elderly patients with recurrent trigeminal neuralgia,those with a DT score≥4(72 patients,57.14%)were more prevalent than those with a DT score<4(54 patients,42.86%).The average DT score for all patients was 4.35±1.72.Patients in the DT score≥4 group were older than those in the DT score<4 group(t=4.207,P=0.000),had lower PSS-Fa scores(t=5.925,P=0.000),and had higher PSQI scores(t=17.858,P=0.000).There were no statistically significant differences in gender,marital status,residence area,education level,disease type,or pain location(all P>0.05).Older age and poor sleep quality were identified as independent risk factors for psychological distress in elderly patients with recurrent trigeminal neuralgia(OR=1.258,OR=1.713,both P<0.05),while higher levels of family support were identified as a protective factor(OR=0.581,P=0.025).Conclusion:Elderly patients with recurrent trigeminal neuralgia experience psychological distress,and the degree of severity depends on age,quality of sleep,and level of family support.

Interpeduncular cistern intrathecal targeted drug delivery for intractable postherpetic neuralgia: A case report

BACKGROUND Intractable postherpetic neuralgia(PHN)can be difficult to manage even with aggressive multimodal therapies.Patients who experience uncontrolled refractory cranial PHN despite conservative treatment may benefit from an intrathecal drug delivery system(IDDS).For craniofacial neuropathic pain,the traditional approach has been to place the intrathecal catheter tip below the level of the cranial nerve root entry zones,which may lead to insufficient analgesia.CASE SUMMARY We describe a 69-year-old man with a 1-year history of PHN after developing a vesicular rash in the ophthalmic division of cranial nerve V(trigeminal nerve)distribution.The pain was rated 7-8 at rest and 9-10 at breakthrough pain(BTP)on a numeric rating scale.Despite receiving aggressive multimodal therapies including large doses of oral analgesics(gabapentin 150 mg q12 h,oxycodone 5 mg/acetaminophen 325 mg q6 h,and lidocaine 5%patch 700 mg q12 h)and sphenopalatine ganglion block,there was no relief of pain.Subsequently,the patient elected to have an implantable IDDS with the catheter tip placed at the interpeduncular cistern.The frequency of BTP episodes decreased.The patient’s continuous daily dose was adjusted to 0.032 mg/d after 3 mo of follow-up and stopped 5 mo later.He did not report pain or other discomfort at outpatient follow-up 6 mo and 1 year after stopping intracisternal hydromorphone.CONCLUSION The use of interpeduncular cistern intrathecal infusion with low-dose hydromorphone by IDDS may be effective for severe craniofacial PHN.

Analgesic effects of different acupuncture therapies on postherpetic neuralgia:a Bayes⁃ian network meta-analysis

OBJECTIVE To assess the effi⁃cacy and safety of acupuncture-related treat⁃ments for postherpetic neuralgia(PHN),identify the most effective acupuncture and related treat⁃ments.METHODS PubMed,Cochrane Central Register of Controlled Trials,Embase,Web of Science,and four Chinese databases,a clinical research registration platform,and grey literature were searched.We evaluated the risk of bias and quality in the included studies and per⁃formed a Bayesian multiple network meta-analysis.RESULTS We included 29 randomized controlled trials comprising 1973 patients,of which approximately 17.24%showed a high risk of bias.According to the Jadad scale,2,16,and 11 studies were high,medium,and low quality,respectively.The pairwise meta-analysis results revealed that the efficacy of all acupuncture-related treatments for pain relief related to PHN showed the difference was statistically significant com⁃pared with that of antiepileptics.The network meta-analysis results showed that pricking and cupping plus antiepileptics were the most effective,followed by electroacupuncture(EA)plus antiepileptics for pain relief in patients with PHN.EA plus antiepileptics ranked the best regarding reduced Pittsburgh Sleep Quality Index and Self-Rating Depression Scale scores in patients with PHN.No results were found regarding total response rate or quality of life among this study.Acupuncture-related treatments showed a lower incidence of adverse events than that of antiepi⁃leptics-related treatments.CONCLUSION Acu⁃puncture-related therapies may be potential treat⁃ment options for PHN and are relatively safe.Pricking and cupping plus antiepileptics are the most effective techniques for pain relief.EA plus antiepileptics is the best approach for improving insomnia and depression symptoms of PHN.

Motor cortex transcranial magnetic stimulation to reduce intractable postherpetic neuralgia with poor response to other threapies:Report of two cases

BACKGROUND Postherpetic neuralgia(PHN)is a typical neuropathic pain condition that appears in the lesioned skin regions following the healing of shingles.The pain condition tends to persist,which is often accompanied by negative emotions(e.g.,anxiety and depression)and substantially reduces the quality of life.In addition to analgesia(e.g.,pregabalin and gabapentin),nerve radiofrequency technology is an effective treatment for intractable PHN.However,there is still a significant portion of patients who do not benefit from this treatment.As a non-invasive form of brain stimulation,repetitive transcranial magnetic stimulation(rTMS)targeting the motor cortex is able to reduce neuropathic pain with grade A evidence.CASE SUMMARY Here we report two cases in which motor cortex rTMS was used to treat intractable PHN that did not respond to initial drug and radiofrequency therapies.Moreover,we specifically investigated rTMS efficacy at 3 mo following treatment.CONCLUSION Motor cortex rTMS can treat intractable PHN that did not respond to initial drug and radiofrequency therapies.

H7N9 avian influenza with first manifestation of occipital neuralgia:A case report

BACKGROUND Most of the first symptoms of avian influenza are respiratory symptoms,and cases with occipital neuralgia as the first manifestation are rarely reported.CASE SUMMARY A middle-aged patient complaining of paroxysmal pain behind the ear was admitted to our hospital.The patient’s condition changed rapidly,and high fever,unexpected respiratory failure,and multiple organ failure developed rapidly.The patient was diagnosed with H7N9 avian influenza based on etiology.CONCLUSION We believe that the etiology of occipital neuralgia is complex and could be the earliest manifestation of severe diseases.The possibility of an infectious disease should be considered when occipital neuralgia is accompanied by fever.Avian influenza is one of these causative agents.

Electroacupuncture alleviates orofacial allodynia and anxiety-like behaviors by regulating synaptic plasticity of the CA1 hippocampal region in a mouse model of trigeminal neuralgia

OBJECTIVE To investigate whether electroacupuncture(EA)ameliorates abnormal trigeminal neuralgia(TN)orofacial pain and anxiety-like behavior by altering synaptic plasticity in the hippocampus CA1.METHODS A mouse infraorbital nerve transection model(pTION)of neuropathic pain was established,and EA or sham EA was used to treat ipsilateral acu⁃puncture points(GV20-Baihui and ST7-Xia⁃guan).Golgi-Cox staining and transmission elec⁃tron microscopy(TEM)were administrated to observe the changes of synaptic plasticity in the hippocampus CA1.RESULTS Stable and persistent orofacial allodynia and anxiety-like behav⁃iors induced by pT-ION were related to changes in hippocampal synaptic plasticity.Golgi stain⁃ings showed a decrease in the density of dendritic spines,especially mushroom-type dendritic spines,in hippocampal CA1 neurons of pT-ION mice.TEM results showed that the density of synapses,membrane thickness of the postsynaptic density,and length of the synaptic active zone were decreased,whereas the width of the synaptic cleft was increased in pTION mice.EA attenu⁃ated pT-ION-induced orofacial allodynia and anx⁃iety-like behaviors and effectively reversed the abnormal changes in dendritic spines and syn⁃apse of the hippocampal CA1 region.CONCLU⁃SION EA modulates synaptic plasticity of hippo⁃campal CA1 neurons,and reduces abnormal oro⁃facial pain and anxiety-like behavior,providing evidence for a TN treatment strategy.

Treatment of postherpetic neuralgia by bone marrow aspirate injection:A case report

BACKGROUND Postherpetic neuralgia(PHN)is the most frequent and a difficult-to-treat complication of herpes zoster(HZ).Its symptoms include allodynia,hyperalgesia,burning,and an electric shock-like sensation stemming from the hyperexcitability of damaged neurons and varicella-zoster virus-mediated inflammatory tissue damage.HZ-related PHN has an incidence of 5%–30%,and in some patients,the pain is intolerable and can lead to insomnia or depression.In many cases,the pain is resistant to pain-relieving drugs,necessitating radical therapy.CASE SUMMARY We present the case of a patient with PHN whose pain was not cured by conventional treatments,such as analgesics,block injections,or Chinese medicines,but by bone marrow aspirate concentrate(BMAC)injection containing bone marrow mesenchymal stem cells.BMAC has already been used for joint pains.However,this is the first report on its use for PHN treatment.CONCLUSION This report reveals that bone marrow extract can be a radical therapy for PHN.

桥小脑角肿瘤继发性三叉神经痛的临床病理特征

目的:桥小脑角(cerebellopontine angle,CPA)肿瘤是继发性三叉神经痛(trigeminal neuralgia,TN)的常见病因,其位置隐蔽,进展缓慢,难以早期发现。本研究旨在探讨CPA肿瘤继发性TN患者的临床病理特征,提高对继发性TN诊治的认识。方法:回顾性分析中南大学湘雅医院2017年1月1日至2022年12月31日收治的116例CPA肿瘤继发TN患者的临床资料和病理结果,分析肿瘤病理类型与临床表现、肿瘤部位、手术方式及疗效的关系。结果:本组病例中95.7%(111/116)为良性肿瘤,3.4%(4/116)为恶性肿瘤,0.9%(1/116)为交界性肿瘤,良性肿瘤以胆脂瘤、脑膜瘤、神经鞘瘤多见。46.6%(54/116)的患者表现为单纯TN,53.4%(62/116)出现其他伴随症状,这取决于不同类型肿瘤的生长部位、生长速度等因素。本组病例手术全切率在90%以上,41.4%(48/116)的患者在切除肿瘤后同期行微血管减压,其中神经鞘瘤占比最高。手术治疗总体有效率达93.9%,神经鞘瘤的有效率高于胆脂瘤、脑膜瘤(均P<0.05);胆脂瘤的复发率显著高于脑膜瘤、神经鞘瘤(均P<0.05)。结论:CPA肿瘤是继发性TN的主要病因,以良性肿瘤多见,恶性肿瘤虽少但容易被漏诊,早期诊治对预后影响很大。不同类型肿瘤在临床症状、手术方式、疗效等方面有所不同,手术策略需兼顾肿瘤切除程度及神经功能保护,必要时行微血管减压术。

带状疱疹后遗神经痛患者治疗前后白介素10水平与疼痛程度和持续时间的相关性分析

目的分析带状疱疹后遗神经痛患者治疗前后白介素10(IL-10)水平与疼痛程度及持续时间的相关性。方法选取2020年6月至2021年12月我院收治的105例带状疱疹后遗神经痛患者,根据患者疼痛程度将患者分为轻中度组及重度组,比较两组患者白细胞、IL-10等实验室指标水平,患者出院后随访1年,记录患者疼痛持续时间,分析IL-10等指标水平与患者疼痛程度及持续时间的相关性。结果在随访期间4例患者失联,按脱落处理,最终纳入患者101例,其中轻中度组75例,重度组26例。两组患者年龄、性别等一般资料及治疗前后白细胞、中性粒细胞百分比水平相比较,差异无统计学意义(均P>0.05)。轻中度组疼痛评分、疼痛持续时间、治疗前超敏C-反应蛋白(Hs-CRP)及IL-10水平均显著低于重度组(t=28.408,23.888,2.726,9.381;均P<0.05);治疗后两组患者各指标均较前好转,但轻中度组患者Hs-CRP及IL-10水平仍显著低于重度组患者(t=4.342,5.966;均P<0.05)。相关性分析显示,治疗前、后IL-10水平与患者疼痛严重程度及持续时间呈显著正相关(r=0.705,0.209,0.739,0.481;均P<0.001);线性回归示,治疗前IL-10及Hs-CRP水平与患者疼痛持续程度显著相关(t=5.240,5.026;均P<0.05)。结论患者治疗前后IL-10水平与患者疼痛严重程度及疼痛持续时间显著相关,可成为患者预后的可靠预测因子,有助于评估患者预后。

神经导航及C臂辅助下经皮三叉神经微球囊压迫术与显微镜下微血管减压术治疗三叉神经痛的有效性及安全性

目的分析神经导航及C臂辅助下经皮三叉神经微球囊压迫术与显微镜下微血管减压术治疗三叉神经痛的有效性及安全性。方法将我院2021年3月至2023年3月收治的84例三叉神经痛患者作为研究对象,以手术方案将其分为球囊组(42例,神经导航及C臂辅助下经皮三叉神经微球囊压迫术)和微血管组(42例,神经导航及C臂辅助经显微镜下微血管减压术)。比较两组的治疗效果。结果两组的治疗总有效率无显著差异(P>0.05)。微血管组术后1年内复发率、并发症总发生率显著低于球囊组(P<0.05)。微血管组的手术时长、总住院时长显著长于球囊组(P<0.05)。术后,微血管组的8-羟基脱氧鸟苷(8-OHdG)、超氧化物歧化酶(SOD)、总抗氧化能力(T-AOC)、去甲肾上腺素(NE)、皮质醇(Cor)、髓过氧化物酶(MPO)水平显著高于球囊组(P<0.05)。结论神经导航及C臂辅助下经皮三叉神经微球囊压迫术与显微镜下微血管减压术治疗三叉神经痛均可取得较佳疗效,但后者较前者的预后效果更佳,而前者较后者的手术应激反应更小,在临床选择中需考虑患者的耐受度与适应证合理进行选择。

三叉神经痛微球囊压迫术后无效或短期内复发机制及处理方法的研究进展

三叉神经痛(TN)是临床常见的疼痛性疾病,而经皮微球囊压迫术(PMC)是TN最有效的治疗方法。但PMC仍存在无效或复发的可能,且复发后病情也更加复杂。同时影响PMC治疗后无效或复发的因素也较多。因此,对于PMC治疗无效或复发的患者,治疗无效或复发的病因、患者的身体状况、治疗的安全性等均是制订PMC治疗无效或复发后干预策略需要考虑的因素。目前关于PMC的治疗尚处于探索阶段,未来深入研究TN经PMC治疗后无效或复发的机制,可以为疾病的治疗提供新思路。
