  • Spinal epidural emphysema is rare and has been described secondary to following medical intervention, such as lumbar puncture and epidural analgesia, pneumothorax or pneumomediastinum, degenerative disk disease, epidural abscess, and trauma. Rarely, it occurs after chest tube placement. We report a case of spinal epidural emphysema incidentally noted on HRCT after chest tube placement.

  • Manual or mechanical compression followed by 4 to 8 hours of bed rest is still the standard technique for accessing site management of the femoral arterial puncture site. But these methods are often uncomfortable and delay hospital discharge. Recently, a number of new devices to achieve hemostasis have been developed. These devices uses collagen to facilitate local hemostasis. But many complications associated with the use these devices have been reported internationally. We present a case of successful treatment of Rt. femoral and Rt. popliteal arteries thrombosis caused by Angioseal.

  • In this study, we discussed the characteristics of breakdown and surface flashover of FRP in L$N_2$ for applying it to spacer of a superconducting power equipment. Fiberglass reinforced plastic(FRP) has high breakdown puncture strength and has high mechanical strength. So the research of its dielectric properties have been conducted in liquid nitrogen($LN_2$). We measured breakdown voltage of FRP and distinguished four types of surface flashover along solid insulator with arrangement of electrodes and measured the surface flashover voltages of each types of electrode arrangement. The type of a electrode set at the back of the insulator showed the worst dielectric property. The property of surface flashover depending on pressure was tested.

  • The NGK suspension insulators are subjected in harsh environments in service above 40 years long time. The long term reliability of the insulators is required for both mechanical and electrical performances. This study describes some electrical performances according to KEPCO-standard. There was fail in electrical and mechanical performance test such as galvanizing, low-frequence wet flashover voltage, puncture and combine mechanical & electrical strength test. The NGK suspension insulators of 1968 were shown lower electrical and mechanical performance than those of 1979.

  • Simultaneous intracranial and spinal subdural hematomas are extremely rare. In most cases, they are attributed to major or minor trauma and iatrogenic causes, such as those resulting from spinal puncture. To the best of the authors' knowledge, there has been only two reports of spontaneous concomitant intracranial and spinal subdural hematomas in a patient receiving anticoagulant therapy who had an absence of evident trauma history. We report on a case of spontaneous concomitant intracranial and spinal subdural hematomas that occurred in association with anticoagulant therapy and present a review of the relevant literature.

  • A lipidomic study on extensive plasma lipids in bacterial peritonitis (cecal ligation and puncture, CLP)-induced sepsis in mice was done at 24 h post-CLP. The effects of administration of lysophosphatidylcholine (LPC) and lysophosphatidic acid (LPA), compounds known to have beneficial effects in CLP, on the sepsis-induced plasma lipid changes were also examined. Among the 147 plasma lipid species from 13 lipid subgroups (fatty acid [FA], LPA, LPC, lysophosphatidylethanolamine [LPE], phosphatidic acid [PA], phosphatidylcholine [PC], phosphatidylethanolamine [PE], phosphatidylinositol [PI], monoacylglyceride [MG], diacylglyceride [DG], triacylglyceride [TG], sphingomyelin [SM], and ceramide [Cer]) analyzed in this study, 40 and 70 species were increased, and decreased, respectively, in the CLP mice. Treatments with LPC and LPA affected 14 species from 7 subgroups, and 25 species from 9 subgroups, respectively. These results could contribute to finding the much needed reliable biomarkers of sepsis.

  • A 9-year-old boy who was confirmed measles by clinical manifestations and serum measles IgM antibody presented with bilateral visual loss 12 days after the onset of maculopapular rash. Complete ophthalmic and neurologic examinations, radiologic studies, and lumbar puncture were performed. Visual acuities were counting fingers in both eyes, with mild bilateral optic disk hyperemia and swelling noted. Neurologic examination was unremarkable, however, a magnetic resonance imaging of the brain showed high signals on basal ganglia, and periventricular white matter. The cerebrospinal fluid was devoid of white cells. Intravenous methylprednisolone and high dose immunoglobulins were administered, and clinical findings resolved completely within 6 months.

  • Implantation of Dual Chamber Pacemakers Which sense in the Atrium and the Ventricle, and sequentially or synchronously trigger impulses in the both chambers, has led us to the near realization of the ideal "Physiologic Pacing". We have experienced two cases of implantation of Dual chamber pacemaker in September and October, 1983. One patient was a 21-year-old male who had postoperative complete heart block since he was taken Total correction of TOF in May, 1983 . We implanted transvenously a dual chamber pacemaker, VDD type, through the left subclavian vein. In the other patient who came to the emergency room for partial obstruction of small bowels with severe abdominal pain, nausea and vomiting, in whom heart block was found, we implanted a DDD type pacemaker through the left subclavian puncture. The pacemakers have been functioning well postoperatively for more than two months, and the conditions of patient were uneventful.

  • We report a patient with spontaneous intracranial hypotension. In addition to the cardinal feature of a postural headache and a low CSF pressure, the patient also had subdural hematoma demonstrated by brain MRI. Radionuclide cisternography revealed a CSF leakage in the intracranium. CSF leakage from spinal meningeal defects may be the most common cause of this syndrome. The headache is a consequence of the low CSF pressure producing displacement of pain-sensitive structures. Methods of treatment are identical to those for post-dural puncture headaches. We experienced a patient with spontaneous intracranial hypotension developed in the intracranium who was successfully managed with a cervical blood patch.

  • Mandibular arteriovenous malformations(AVM) are relatively rare and potentially life threatening lesions. Surgical treatment consists of wide resection of the mandible, which is difficult and potentially hazardous due to significant blood loss during surgery. Therefore, some authors advocate that transvenous embolization may be a safer and more effective method in the treatment of mandibular AVM. We report a treatment case of mandibular AVM in a 9-year-old-girl for episodes of spontaneous bleeding for 6 days using by selective transarterial embolization, direct puncture embolization and microcoil embolization.
