AIM: To evaluate the safety and efficacy of the permanent high interventricular septal pacing in a long term follow up, as alternative to right ventricular apical pacing. METHODS: We retrospectively evaluated:(1) 244 patients(74 ± 8 years; 169 men, 75 women) implanted with a single(132 pts) or dual chamber(112 pts) pacemaker(PM) with ventricular screw-in lead placed at the right ventricular high septal parahisian site(SEPTAL pacing);(2) 22 patients with permanent pacemaker and low percentage of pacing( 80%) right ventricular apical pacing(RVA). All patients had a narrow spontaneous QRS(101 ± 14 ms). We evaluated New York Heart Association(NYHA) class, quality of life(Qo L), 6 min walking test(6MWT) and left ventricular function(end-diastolic volume, LV-EDV; end-systolic volume, LVESV; ejection fraction, LV-EF) with 2D-echocardiography. RESULTS: Pacing parameters were stable duringfollow up(21 mo/patient). In SEPTAL pacing group we observed an improvement in NYHA class, Qo L score and 6MWT. While LV-EDV didn't significantly increase(104 ± 40 m L vs 100 ± 37 m L; P = 0.35), LV-ESV slightly increased(55 ± 31 m L vs 49 ± 27 m L; P = 0.05) and LV-EF slightly decreased(49% ± 11% vs 53% ± 11%; P = 0.001) but never falling < 45%. In the RVA pacing control group we observed a worsening of NYHA class and an important reduction of LV-EF(from 56% ± 6% to 43% ± 9%, P < 0.0001).CONCLUSION: Right ventricular permanent high septal pacing is safe and effective in a long term follow up evaluation; it could be a good alternative to the conventional RVA pacing in order to avoid its deleterious effects.

AIM:To clarify whether the vasoconstrictory response is impaired and to study vascular function in patients with migraine during the headache ***:We studied vascular reactivity in the resistance arteries by using the forearm perfusion technique associated with *** measuredforearm blood flow by strain-gauge plethysmography during intra-brachial infusion of acetylcholine,sodium nitroprusside or norepinephrine in 11 controls and 13patients with migraine,11 of them(M) in the interval between the migraine attacks and 4 during a headache attack(MH).Written informed consent was obtained from patients and healthy controls,and the study was approved by the Ethics Committee of the University Federico Ⅱ.RESULTS:Compared to healthy control subjects,in patients with migraine studied during the interictal period,the vasodilating effect of acetylcholine,that acts through the stimulation of endothelial cells and the release of nitric oxide,was markedly reduced,but became normal during the headache attack(P0.05).CONCLUSION:In migrainers,the impaired relaxation of VSMCs is restored during the headache *** vasoconstrictory response is impaired and remains unchanged during the migraine attack.

背景与目的通过意大利放射治疗和临床肿瘤学学会(Italian Association of Radiotherapy and Clinical Oncology, AIRO)的一项多中心回顾性研究,明确免疫疗法(immunotherapy, IT)和立体定向放疗(stereotactic radiotherapy,SRT)包括放射外科治疗(radiosurgery, RS)或大分割立体定向放疗(hypofractionated stereotactic radiotherapy, HFSRT)治疗非小细胞肺癌(non-small cell lung cancer, NSCLC)脑转移的疗效和毒性。方法对来自19个意大利中心接受SRT+IT的NSCLC伴脑转移患者进行分析,并与单独接受SRT的对照组患者进行比较。结果共纳入SRT+IT组100例和单独SRT组50例。接受SRT+IT的患者有更长的颅内局部无进展生存期(intracranial local progression-free survival, i LPFS)(经倾向性评分调整后,P=0.007)。在诊断为脑转移时接受IT合并有颅外进展的患者中(n=24),接受SRT后再进行IT与较好的总生存期(overall survival, OS)相关(P=0.037)。多因素分析显示组织学类型为非腺癌、卡氏体能状态(Karnofsky performance status,KPS)评分=70分以及接受HFSRT与显著减少的生存期相关(P值分别为0.019、0.017和0.007)。与SRT和IT治疗间隔>7天(n=10)相比,治疗间隔≤7天(n=90)与更长的OS相关(经倾向性评分调整后,P=0.008)。联合治疗耐受性良好。在放射性坏死方面,接受SRT+IT的患者与单独SRT的患者无显著差异。SRT和IT的治疗间隔对毒性发生率无影响。结论 SRT+IT是一种安全的联合治疗方法,与单独SRT相比,具有更长的i LPFS。
