Seizure is a foreseeable risk in patients with brain lesion. However, seizure during treating non-brain lesion is not a familiar situation to neurosurgeon. Posterior reversible encephalopathy syndrome (PRES) is a relatively common situation after systemic chemotherapy. The aim of this study is to make neurosurgeons aware of this potential medical problem. A 52-year-old woman with advanced gastric cancer, presented with low back pain due to spinal metastasis at the 4th lumbar vertebra. Ten cycles of chemotherapy with FOLFOX (5-Fluoruracil/Oxaliplatin) had been completed 23 days ago. Two days before the planned operation, a generalized tonic clonic seizure occurred. She did not have a history of hypertension or seizure. The seizure was stopped with lorazepam 4mg. The brain magnetic resonance (MR) imaging showed high signal changes in both parieto-occipital lobes on the T2-weighted images, and these were partially enhanced, suggesting PRES. The surgery was preceded by treatment with an antiepileptic drug. The MR images, taken 1.5 months after the seizure, showed that the lesion was no longer present. At 3 month follow-up, no additional seizure attack occurred without any seizure medication. The possibility of a seizure attack should be considered if the patient has a history of chemotherapy.

Extra-anatomic bypass was proposed by Freeman in 1952 and has been used for patient with lower extremity arterial occlusion who had very high operative risk, especially elderly or severly illed patient.We had performed 14 cases of extra-anatomic bypasses from Jan. 1991 till July 1993 and having been following up them. Their results were summarized as follow. Among total 14 patients, 13 was male. Their mean age was 64.8 years old, ranged from 48 to 80. The most common complaint was pain on lower limb and they visited hospital 6.1 months in average after onset of symptom. Frequently, they were associated with systemic diseases such as generalized atherosclersis, hypertension, diabetes mellius, etc. Axillary artery was used as donor artery in 8 cases and crossover femoro-femoral or femoro-popliteal bypass was performed in 6 cases. Postoperative complications were notedd in 8 cases so their morbidity rate was 42.8%. Except for two contraindicated cases, one or more anticoagulants were used routinely . Among them, combined use of aspirin and persantine was most commonly applied.After bypass graft, nine cases were occluded beteween 10 and 53 months. So their average duration of freedom from reocclusion was 35.7 months and 3-year patency rate was 63%.

Background: A physical therapy is required to restore motor function of stroke patients, especially gait function improvement is very important to them. Design: Systemic review. Methods: The purpose of this study is to provide objective evidence for the effectiveness of the treadmill training method applied to stroke patients. The literature search for a systematic review was performed on domestic data published from 2010 to 2020 at KISS, RISS, and DBpia. Results: 40 papers meeting the inclusion/exclusion criteria were finally selected. Data analysis was performed according to the research type, intervention method and process, measurement variables, and the risk of bias assessment was conducted as quality evaluation. Conclusion: Various training methods have been suggested and proved that treadmill intervention is an effective method for improving gait and balance. As the goal of rehabilitation for stroke patients is to improve walking and balance, we expect continuous clinical research to continue to establish a more systematic training program and present a new paradigm.

Objectives The objective of this study is to assess the effectiveness of electroacupuncture for patients with hip arthroplasty. Methods According to participants, intervention, comparison, outcome, study design, we searched for clinical studies that conducted electroacupuncture for patients with hip arthroplasty. Results Finally 11 randomized controlled trials were chosen for systemic review and meta-analysis. The frequently used evaluation tools were Incidence of postoperative cognitive dysfunction (POCD), heart rate, blood pressure. Almost studies showed electroacupuncture has effects for patients with hip arthroplasty. Through meta analysis, Electoacupuncture showed statistically significant effect of reducing the anesthetic dosage and incidence of postoperative psychonosema and adverse reactions in intra-operation period, reducing the incidence of POCD in peri-operation period, incidence of deep venous thrombosis in post-operation period. Conclusion 11 studies reported that electroacupuncture has significant effects on hip arthroplasty. But, many studies were assessed in a probable high risk of bias. And all studies published in one overseas country. So, it requires attention to comprehend this study. To make up for this limitaion, more well designed clinical research are needed.

We report the case of a 43-year-old male with both giant left atrial appendage (LAA) aneurysm and drug-refractory atrial fibrillation (AF). The patient was treated with percutaneous electrical isolation of cardiac arrhythmogenic substrate, and has been free of AF symptom over one year. Although the surgical resection of giant LAA aneurysm is mostly used to prevent systemic thromboembolism, we have performed follow-up of the giant LAA aneurysm using cardiac magnetic resonance (CMR) imaging and transesophageal echocardiography (TEE) after the successful catheter ablation of refractory AF. At one-year follow-up CMR, the giant LAA aneurysm showed remarkable enlargement as well as decreased contractility. Additionally, one-year follow-up TEE showed spontaneous echo contrast as an indicator of blood stasis in the giant LAA aneurysm. Those findings of giant LAA aneurysm suggest that the risk of thromboembolism may be high despite termination of AF.

As a public transportation possible to convey a large quantity, the railway is safe and keeps time, but it has hazards to cause a disaster if the accidents such as collision, derailment, and fire occur. So advanced countries carry out System Safety Plan with various program activities which have connected orders to maintain or improve safety level by finding hazards, evaluation, taking measures and practice, and improving problems. Especially they systematically manage hazards to cause railway accidents and the factors which possibly threat safety, using national classification of risk and causes with analysis of the related data such as establishing accident/incident data and safety regulations/standards. As executing railway safety regulations, domestic railway is currently trying to improve railway safety management system. The research of classification system of accidents/incidents is one thing to make railway safety management systems better. In this research, we reviewed hazardous factors of railway systems and classification of the causes as the beginning of system safety management, and we conducted study on development of railway accident classification based on findings of this research. The results are able to be used in identifying hazards and activities of systemic safety management at the step of railway accident report and investigation.

Since the first description of bisphosphonate related osteonecrosis of the jaw (BRONJ) in 2002, the number of report on the disease has rapidly been increasing. Now, BRONJ is considered as a new entity, which is emerging problem in oral and maxillofacial surgery. Bisphosphonates (BPs) can be categorized into 2 groups: nitrogen-containing and non-nitrogen containing, and nitrogen-containing BPs are considered to have more efficacy and toxicity possibly. It is unusual for osteonecrosis to occur in the maxilla but BRONJ is found in both the mandible and the maxilla, which is one of the special features of BRONJ compared with common infectious osteomyelitis of the jaws. Intravenous BPs are usually more likely to cause BRONJ than oral BPs which are frequently prescribed for osteoporosis and osteopenia. Nonetheless, the use of intravenous BPs cannot be prevented because of systemic condition of the patients. Although it is rare that oral BPs cause BRONJ in osteoporosis/osteopenia patients, we should be aware of BRONJ since the population of the patients is exceedingly increasing with the prolonging of life expectancy. So, we'd like to enlighten upon the problems and solutions of BRONJ.

Vertebroplasty and kyphoplasty are well-known, useful techniques for the treatment of painful vertebral compression fractures. Although the risk associated with these procedures is low, serious complications can occur. Of these complications, infection is even rarer, however, when it does occur, it is difficult to manage and can become life-threatening. We describe here a case of infectious spondylitis with epidural inflammation that occurred after performing kyphoplasty in a patient who had a thoracic vertebra compression fracture. We reviewed other case and literatures. Extreme asepsis of the operating theater, screening and treatment for systemic infection prior to the procedure, as well as the use of appropriate antibiotic prophylaxis are strongly recommended when conducting kyphoplasty to prevent infection.
