谈医疗设备漏电对人体的电击

医疗设备可以为临床工作提供大量诊断信息和治疗手段，而医疗设备的漏电也会使病人电击灼伤以至危及生命。国务院发布《医疗事故处理条例》以后引起了医疗界高度重视，临床诊疗活动中如何安全使用医疗设备也是预防医疗事故的重要方面。本文着重介绍了电击的种类、对人体的危害及防护措施。     

Intermittent claudication associated with persistent sciatic artery: Report of two cases

Two elderly women complaining of intermittent claudication complicated with persistent sciatic artery are herein reported. A direct femoral arteriogram showed hypoplasty of the superficial femoral artery and an unnatural anatomical relationship between the distal superficial femoral artery and the proximal popliteal artery, thus suggesting the presence of persistent sciatic artery. The diagnosis of persistent sciatic artery was finally made based on the aortography findings including the iliac arterial system and computed tomography (CT) scan. Magnetic resonance imaging (MRI) was helpful to demonstrate the entire image of this anomaly in cases with non-thrombolized sciatic artery. These diagnostic methods were useful in designing the optimal surgical strategy. The first case with a gluteal pulsating mass underwent exclusion of the persistent sciatic artery including the aneurysm through a retroperitoneal approach with a combination of femorotibial bypass, while the second case with thrombosed persistent sciatic artery only underwent femoropopliteal bypass. To recognize such a rare lesion, awareness of the differential diagnosis is important, and to provide appropriate treatment, an accurate whole image including adequate angiography, a CT scan, and magnetic resonance imaging is necessary.

In vivo activity and metabolic fate of 2-(2,3,3-triiodoallyl)tetrazole (ME1401), a novel antifungal agent

2-(2,3,3-Triiodoallyl)tetrazole (ME1401), a novel antifungal agent, showed therapeutic effectiveness in topical treatment of experimental dermal infections with Trichophyton mentagrophytes and Candida albicans in guinea-pigs. Addition of diethyl sebacate to the ME1401 preparations increased its in vivo antifungal activity and its penetration into the skin. When the estimation of efficacy of treatment with active formulations was made on the basis of skin lesion and the rate of negative skin cultures in comparison with those for infected, untreated or placebo-treated controls, the in vivo activity of 0.5% ethanol tincture or gel of ME1401 was comparable to that of reference antimycotic drugs such as clotrimazole, haloprogin and others. Pharmacokinetic studies in the experimental animals demonstrated that ME1401 was unstable in vivo, being readily converted to an active metabolite 2-(3-iodopropargyl)tetrazole (CN144) first and then to 2-propargyltetrazole (CN151). CN144 showed potent in vitro and in vivo antifungal activities, while the in vitro activity of CN151 was negligible.     

人参茎叶总皂甙对实验性小鼠生殖细胞遗传物质损伤的影响

本文采用小鼠精原细胞姐妹染色单体互换（ＳＣＥ）实验方法，研究了人参茎叶总皂甙（ＧＮＳ）对丝裂霉素Ｃ（ＭＭＣ）引起的小鼠精原细胞遗传物质损伤的影响。结果表明，ＧＮＳ不能诱发小鼠精原细胞ＳＣＥ，而且在腹腔注射ＭＭＣ的同时给予ＧＮＳ，可使ＭＭＣ诱发的小鼠精原细胞ＳＣＥ频率明显降低。为此，我们认为ＧＮＳ对小鼠生殖细胞遗传物质具有保护作用。     

Diastematomyelia presenting as progressive weakness in an adult after spinal fusion for adolescent idiopathic scoliosis.

BACKGROUND CONTEXT: Diastematomyelia is uncommon and rarely presents in adulthood. This report draws attention to the fact that patients who underwent spinal fusion for deformity before the widespread use of computed tomography (CT) and magnetic resonance imaging (MRI) may have unrecognized spinal cord abnormalities. This should be considered if revision surgery is contemplated. PURPOSE: This case report focuses on the late presentation of lower-extremity weakness in a 44-year-old woman with a split cord malformation (diplomyelia), diastematomyelia and tethered cord syndrome. STUDY DESIGN/SETTING: METHODS: The patient underwent instrumented posterior spinal fusion with a Harrington rod as a child for progressive thoracolumbar scoliosis. As an adult, she developed paraparesis after a traumatic event.The patient underwent decompressive laminectomy, subtotal resection of the old fusion mass and resection of the osseous septum. Postoperatively, an anterior spinal fluid leak in the lower thoracic region required repeated fascial grafting, resection of a pseudomeningocele and reverse left latissimus dorsi flap transfer. The leak was controlled, and the patient had near complete resolution of her paraparesis 1 year after her surgery. RESULTS: The case described herein is unusual in that patients with diplomyelia and diastematomyelia rarely are symptomatic in adulthood. However, trauma may precipitate the onset of neurologic symptoms. This patient underwent spinal surgeries to address deformity, pain and progressive lower-extremity weakness. Preoperative CT and MRI studies showed a split cord malformation and diastematomyelia at L1-L2 with spinal stenosis and tethering of both hemicords. CONCLUSIONS: Progressive weakness without any previous neurologic deficit or neurocutaneous stigmas of an underlying spinal cord abnormality may develop in the adult with unrecognized diastemotomyelia. This case demonstrates that a thorough preoperative workup of patients with complex spinal deformities is imperative.
