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。     

特发性肺纤维化急性加重期证候与血清生物标志物的相关性研究＊

目的 通过分析特发性肺纤维化急性加重期（AE-IPF）患者证候与血清生物标志物的关系，为中医辨证治疗提供参考。方法 采用观察性研究设计，收集2019年3月至2019年11月三个中心的AE-IPF患者76例，其中痰热壅肺证26例、痰浊阻肺证50例，并纳入健康志愿者10例作为对照。采用ELISA测定患者血清CCL18、HMGB1、KL-6、MMP-7、SP-A和SP-D水平，分析与中医证候的相关性。结果 AE-IPF患者血清CCL18、HMGB1、KL-6、MMP-7、SP-A和SP-D水平均显著高于健康对照组。血清CCL18、HMGB1、KL-6、MMP-7和SP-D水平在痰热壅肺证和痰浊阻肺证患者间无显著性差异（P＞0.05），而血清SP-A水平存在显著性差异（P＜0.05）。结论 血清SP-A与AE-IPF证候存在一定的相关性，血清SP-A的浓度升高，与痰热壅肺证关系越密切，反之，血清SP-A浓度降低，则与痰浊阻肺证关系越密切。AE-IPF痰热壅肺证患者的预后可能较痰浊阻肺证患者更差。     

郭军教授治疗特发性男性不育症的经验

男性不育症中,精液分析多种参数异常且无法找到明确病因的称为特发性男性不育症,其发病率不断提高,给国内甚至全球范围内家庭带来精神及经济负担。由于病因不明确,目前现代医学尚无有效治疗方法。传统中医药通过辨证论治在治疗特发性男性不育症时具有优势,郭军教授认为该病以肾脾两虚为本,为体内湿热形成奠定基础,患者久病无子嗣,肝气不畅则郁结,气血津液运行不通则夹血瘀湿热等有形实邪,另外怪病多痰。故对于特发性男性不育症,治法注重补泻兼施,扶正祛邪,补益脾肾为主,对于湿热、痰湿、瘀血则清热祛湿化痰,活血化瘀等,并举验案1例。     

Comparative study of the substantia nigra echogenicity and 123I-Ioflupane SPECT in patients with synucleinopathies with and without REM sleep behavior disorder

ObjectivesHyperechogenicity of the substantia nigra (SN) and abnormal dopamine transporter-single-photon emission computed tomography (DAT-SPECT) are biomarkers commonly used in the assessment of prodromal synucleinopathy. Our goals were as follows: (1) to compare echogenicity of SN in idiopathic rapid eye movement (REM) behavior disorder (iRBD), Parkinson's disease (PD) without RBD (PD-noRBD), PD with RBD (PD + RBD), and control subjects; and (2) to examine association between SN degeneration assessed by DAT-SPECT and SN echogenicity.Patients/methodsA total of 61 subjects with confirmed iRBD were examined using Movement Disorders Society-unified PD rating scale (MDS-UPDRS), TCS (transcranial sonography) and DAT-SPECT. The results were compared with 44 patients with PD (25% PD + RBD) and with 120 age-matched healthy subjects.Results and conclusionThe abnormal SN area was found in 75.5% PD, 23% iRBD and 7.3% controls. Median SN echogenicity area in PD (0.27 ± 0.22 cm²) was higher compared to iRBD (0.07 ± 0.07 cm²; p < 0.0001) and controls (0.05 ± 0.03 cm²; p < 0.0001). SN echogenicity in PD + RBD was not significantly different from PD-noRBD (0.30 vs. 0.22, p = 0.15).Abnormal DAT-SPECT was found in 16 iRBD (25.4%) and 44 PD subjects (100%). No correlation between the larger SN area and corresponding putaminal binding index was found in iRBD (r = −0.13, p = 0.29), nor in PD (r = −0.19, p = 0.22).The results of our study showed that: (1) SN echogenicity area in iRBD was higher compared to controls, but the hyperechogenicity was present only in a minority of iRBD patients; (2) SN echogenicity and DAT-SPECT binding index did not correlate in either group; and (3) SN echogenicity does not differ between PD with/without RBD.     

Efficacy of percutaneous and transcutaneous tibial nerve stimulation in women with idiopathic overactive bladder: A prospective randomised controlled trial

BackgroundDifferent studies have reported the efficacy of percutaneous tibial nerve stimulation (PTNS) and transcutaneous tibial nerve stimulation (TTNS) in treating idiopathic overactive bladder (OAB). However, no study has compared the effectiveness of PTNS and TTNS added to bladder training (BT) in idiopathic OAB.ObjectiveTo compare the efficacy of PTNS and TTNS added to BT in women with idiopathic OAB.MethodsWe randomised 60 women with idiopathic OAB into 3 groups. Group 1 (n = 19) received BT, Group 2 (n = 19) received PTNS in addition to BT, and Group 3 (n = 20) received TTNS in addition to BT. PTNS and TTNS were performed 2 days a week, for 30 min a day, for a total of 12 sessions for 6 weeks. Patients were evaluated by incontinence severity (pad test), a 3-day voiding diary (frequency of voiding, incontinence episodes, nocturia and number of pads used), symptom severity, quality of life, treatment success (positive response rate), treatment satisfaction (Likert scale), discomfort level and preparation time for stimulation (sec).ResultsAt the end of treatment; severity of incontinence, frequency of voiding, incontinence episodes, nocturia, number of pads used, symptom severity and quality of life were significantly improved in Groups 2 and 3 versus Group 1 (P < 0.0167). Treatment success and treatment satisfaction were higher in Groups 2 and 3 than Group 1 (P < 0.001 and P < 0.0167, respectively). Level of discomfort was lower, treatment satisfaction was higher and preparation time for stimulation was shorter in Group 3 than Group 2 (P < 0.05).ConclusionBoth the PTNS plus BT and TTNS plus BT were more effective than BT alone in women with idiopathic OAB. These 2 tibial nerve stimulation methods had similar clinical efficacy but with slight differences: TTNS had shorter preparation time, less discomfort level and higher patient satisfaction than PTNS.

Eficacia de la terapia con señales electromagnéticas pulsadas y transmitidas de manera dieléctrica monopolar en procesos dolorosos asociados a esclerosis múltiple. Estudio piloto

IntroductionPain is highly prevalent in patients with multiple sclerosis (MS); it is chronic in 50% of cases and is classified as nociceptive, neuropathic, or mixed-type. Pain affects quality of life, sleep, and the activities of daily living. Electrotherapy is an interesting alternative or complementary treatment in the management of pain in MS, with new innovations constantly appearing.Material and methodsThis study evaluates the effectiveness of treatment with monopolar dielectric transmission of pulsed electromagnetic fields (PEMF) for pain associated with MS. We performed a randomised, placebo-controlled clinical trial including 24 patients, who were assessed with the Brief Pain Inventory, the Multiple Sclerosis International Quality of Life questionnaire, the Beck Depression Inventory, and the Modified Fatigue Impact Scale.ResultsStatistically significant improvements were observed in maximum and mean pain scores, as well as in the impact of pain on work, personal relationships, and sleep and rest. Not significant differences were found between the treatment and placebo groups.ConclusionsTreatment with PEMF may be effective in reducing pain in patients with MS, although further research is necessary to confirm its effectiveness over placebo and to differentiate which type of pain may be more susceptible to this treatment.     

Tratamiento empírico de la oligoastenoteratozoospermia idiopática

Male infertility accounts for 50% of the causes of infertile couples, being more than 30% of unknown etiology. In these cases, empiric treatment can be an option prior to the application of assisted reproduction techniques. Empiric treatment can be categorized as hormonal, such as gonadotropins, antiestrogens and aromatase inhibitors, and antioxidant, with vitamins, trace elements and carnitine, among others. Although scientifically acceptable evidence is limited due to the absence of large randomized and controlled clinical trials, recent systematic reviews and meta-analyses show that treatment with gonadotropins, antiestrogens and antioxidants increases pregnancy and live birth rates and improves seminal parameters. Empiric medical treatment for idiopathic infertility can be considered in specific cases in order to improve semen quality and spontaneous fertility.
