短时程脊髓电刺激治疗爆发痛合并触诱发痛的急性期带状疱疹的临床研究

目的探讨短时程脊髓电刺激(temporary spinal cord stimulation, tSCS)治疗爆发痛合并触诱发痛的急性期带状疱疹的临床疗效。方法回顾性地分析同济大学附属第十人民医院疼痛科2020年1月—2020年12月收治的52例接受tSCS治疗的爆发痛合并触诱发痛的急性期带状疱疹患者的临床资料，评估在治疗前、治疗后3d、7d、14d、3个月、6个月的总体疼痛情况(numerical rating scale, NRS)评分、(simple McGill scores, McGill)评分、爆发痛情况(发生率、NRS评分、次数以及持续时间)、触诱发痛情况(发生率、分级)、术后不良反应等；评估在治疗前、治疗后7d、3个月、6个月的睡眠时长、睡眠中醒来次数、疼痛障碍指数(pain disorder index, PDI)、功能状态评分(Karnofsky score, KPS)、抑郁症筛查量表(patient health questionnaire depression module scale, PHQ-9)和焦虑症筛查量表(generalized anxiety disorder-7 scale, GAD-7)等。结果与治疗前相比，治疗后3d、7d、14d、3个月、6个月的总体疼痛NRS评分、总体疼痛MCGILL评分、静息痛NRS评分明显降低(均P<0.001)；与治疗前相比，治疗后3d、7d、14d、3个月、6个月的的爆发痛NRS评分明显降低(均P<0.05)，治疗后14d、3个月、6个月时的爆发痛次数以及持续时间都明显降低(均P<0.05)；与治疗前比较，患者治疗后7d、14d、3个月、6个月时的触诱发痛的分级都明显降低，差异均有统计学意义(均P<0.05)；与治疗前相比，治疗后14d、3个月、6个月的PDI评分明显降低(P<0.05)；与治疗前相比，治疗后14d、3个月、6个月的PHQ-9评分和GAD-7评分都明显减少(P<0.05)，与术前的药物使用情况相比，治疗后各镇痛药使用人数普遍呈下降趋势；术中及整个随访期间未观察到严重不良事件。结论短时程脊髓电刺激对爆发痛合并触诱发痛的急性期带状疱疹具有较好的临床疗效。     

Higher Preimplantation Opioid Doses Associated With Long‐Term Spinal Cord Stimulation Failure in 211 Patients With Failed Back Surgery Syndrome

ObjectiveSpinal cord stimulation (SCS) is an effective treatment in failed back surgery syndrome (FBSS). We studied the effect of preimplantation opioid use on SCS outcome and the effect of SCS on opioid use during a two-year follow-up period.Materials and methodsThe study cohort included 211 consecutive FBSS patients who underwent an SCS trial from January 1997 to March 2014. Participants were divided into groups, which were as follows: 1) SCS trial only (n = 47), 2) successful SCS (implanted and in use throughout the two-year follow-up period, n = 131), and 3) unsuccessful SCS (implanted but later explanted or revised due to inadequate pain relief, n = 29). Patients who underwent explantation for other reasons (n = 4) were excluded. Opioid purchase data from January 1995 to March 2016 were retrieved from national registries.ResultsHigher preimplantation opioid doses associated with unsuccessful SCS (ROC: AUC = 0.66, p = 0.009), with 35 morphine milligram equivalents (MME)/day as the optimal cutoff value. All opioids were discontinued in 23% of patients with successful SCS, but in none of the patients with unsuccessful SCS (p = 0.004). Strong opioids were discontinued in 39% of patients with successful SCS, but in none of the patients with unsuccessful SCS (p = 0.04). Mean opioid dose escalated from 18 ± 4 MME/day to 36 ± 6 MME/day with successful SCS and from 22 ± 8 MME/day to 82 ± 21 MME/day with unsuccessful SCS (p < 0.001).ConclusionsHigher preimplantation opioid doses were associated with SCS failure, suggesting the need for opioid tapering before implantation. With continuous SCS therapy and no explantation or revision due to inadequate pain relief, 39% of FBSS patients discontinued strong opioids, and 23% discontinued all opioids. This indicates that SCS should be considered before detrimental dose escalation.

目的 探讨脊柱后路内固定术后硬膜外血肿的预防与护理体会。方法 遵照回顾性分析法选择我院2013年2 月～2018 年2 月纳入的60 例脊柱后路内固定术患者，依照不同理疗方式进行分组。其中30 例给予常规药物治疗作为对照组，另30 例除了常规治疗之外实施综合护理作为研究组，记录两组硬膜外血肿、腰椎术后血肿及颈椎术后血肿发生率，分别在干预前后进行生活质量评分（QOL）调查，出院时发放满意度调查问卷表，对比两组干预结果。结果 研究组血肿发生率为6.67%，明显低于对照组的20.00%（P＜0.05）。干预前两组的食欲、精神、睡眠、疼痛及日常生活评分相比差异无统计学意义（P＞0.05），干预后研究组的各项评分均高于对照组（P＜0.05）。研究组对干预效果的满意度为90.00%，明显高于对照组的76.67%（P＜0.05）。结论 护理干预运用于脊柱后路内固定中效果显著，能够有效减少硬膜外血肿的发生率，提升生活质量，促进病情稳定，患者满意度较高，可维持良好医患关系。     

CyclinA1 Promoter Methylation in Self-Sampling Test

Background: Self sampled HPV testing is a cervical cancer screening method . However, cytology in self-sampled specimen cannot be used as a triage test.  Therefore, other methods for triage should be considered. CyclinA1 (CCNA1) promoter methylation has strong association with cervical precancerous and cancerous lesion. The objective of this study was to compare the diagnostic value of CCNA1 and self-sampled specimen for detecting high-grade cervical intraepithelial lesions or worse (CIN2+). Materials and Methods: A cross sectional study was conducted. Women with abnormal cytology or positive for high risk HPV (hrHPV) indicated for colposcopic examination were enrolled.  Self-collected sampling for hrHPV DNA (SS-HPV) and CCNA1 were performed. hrHPV DNA testing was done by Cobas 4800 method. CCNA1 promoter methylation was detected by CCNA1 duplex methylation specific PCR. Histopathologic result as CIN2+ obtaining from colposcopic directed biopsy or excisional procedure  was considered as positive a gold standard. The results of hrHPV and CCNA1 were reported as positive or negative. Sensitivity specificity, positive predictive value, and negative predictive value of SS-HPV and CCNA1 were calculated by comparing the results with the gold standard. Results: Two hundreds and eighty women were recruited. High-grade cervical lesions and cervical cancer (CIN2+) were diagnosed in 21.8% (61 cases) of the patients. The most common type of hrHPV was non 16, 18 subtype, followed by HPV16 and 18. CCNA1 was positive in 13 patients out of whom, twelve were CIN2+. Sensitivity of CCNA1 was 19.7 % and its  specificity and accuracy were 99.5% and 82.14%, respectively.  The sensitivity of SS-HPV was 70.5%, and its  specificity and accuracy were 39.2% and 43.3%, respectively. Conclusion:  Due to high specificity and positive predictive value of CCNA1, it can be used as alarming sign of having high-grade cervical intraepithelial lesions, especially in patient who has positive hrHPV DNA test based on self-collected sampling.     

Five‐year efficacy of finasteride in 801 Japanese men with androgenetic alopecia

Finasteride is standard medical treatment for androgenetic alopecia; however, no large studies with 5 years or more of follow up have been performed in Japan. The authors followed Japanese men with androgenetic alopecia treated with finasteride for 5 years to evaluate long‐term treatment efficacy. Of 903 men treated with finasteride (1 mg/day), 801 patients were evaluated over 5 years by modified global photographic assessment. Although the proportion of improvement was high (99.4%), modified global photographic assessment scores after 5 years of treatment were lower in patients with more advanced disease as measured by the modified Norwood–Hamilton scale. After separating patients into “sufficient” and “insufficient” efficacy groups according to the modified global photographic assessment score after 5 years (scores ≥6 and <6, respectively), multivariate analysis showed that independent risk factors of insufficient efficacy were age at start of treatment of 40 years or more (P = 0.021) and classification on the modified Norwood–Hamilton scale (P < 0.001), whereas presence of stress at start of treatment was a negative predictor (P = 0.025). In conclusion, continuous finasteride treatment for 5 years improved androgenetic alopecia with sustained effect among Japanese. Younger age and less advanced disease at start of treatment were the key predictors of higher finasteride efficacy.

宫颈癌对妇女健康构成严重威胁,人乳头瘤病毒感染与宫颈病变及宫颈癌的发生密切相关。关于宫颈癌发生发展的机制仍在研究中。近年研究发现一种多功能核蛋白,即死亡结构域相关蛋白(death domain associated protein,Daxx),其与细胞内蛋白或病毒蛋白相互作用,参与调节细胞凋亡、转录调控、抗病毒等细胞活动,在不同途径中发挥不同的生理或病理作用。通过对Daxx功能及其作用机制的研究有助于进一步阐明宫颈癌发生发展的机制,有助于发现新的预防和治疗方法。综述Daxx的一般特性和研究现况及其在宫颈病变的研究进展。     

Nerve ultrasound reference data in children from two to seven years

ObjectiveWe examined selected peripheral and spinal nerves of children aged between two and seven years.MethodHigh resolution ultrasound was performed in 116 children (2–7 years of age) at 19 predefined landmarks of median, ulnar, tibial, fibular, sural and radial nerves, the vagus as well as cervical spinal nerve 5 and 6. Further, side-to-side measuring and grey-scale analysis was done at selected nerve sites.ResultsNerves of children were on average smaller than those of adults. Nerve growth correlates significantly with age in all nerves, the mean values were similar in the age of two to four years and five to seven years. Body mass index (BMI) and gender showed moderate effect at some nerve sites, however not uniformly in all. A side-to-side difference of up to 30% in median, and up to 20% in tibial nerve can occur in healthy individuals. Grey-scale analysis for echointensity has been performed in median, ulnar and tibial nerves.ConclusionNerve size increases with age, BMI and gender have moderate effect. A side-to-side-difference of up to 30% can exist.SignificanceReference values of nerve cross-sectional area, side-to-side-difference and echo intensity are necessary to detect nerve pathology in children as well as in adults.
