A case of trigeminal neuralgia caused by a contralateral acoustic neurinoma is presented. After removal of the tumor, the neuralgic pain has completely disappeared. The pathophysiology of this entity is briefly reviewed. The neuralgic pain may be caused by the compression of the contralateral trigeminal nerve by the mass effect in this case.

The changes of total ascorbic acid level in the spinal cord tissues following experimental spinal cord injury were observed in the 20cats. Three small areas (2×1.5㎝ sized) in the thoracic cord following laminectomy were made and the specimens were removed in one control and the other two areas after 5 & 30minutes following impact injury respectively in each cat. The significant decrease of the total ascorbic acid level after 5 & 30 minutes following experimental spinal cord injury was found.

Twelve patients with recurrent malignant glioma were treated with combination chemotherapy, consisting of procarbazlne(60㎎/㎡, 8th-21th day), CCNU(110㎎/㎡. 1st day), and vincristine(1.4㎎/㎡. 8th and 29th day) every 6 weeks. Most patients had undergone initial resection of primary tumor, postoperative radiotherapy, and another form of chemotherapy. Response or progression was defined as improvement or deterioration in MRI scan. Assessment of response followed evaluation of MRI obtained after the completion of each two cycles of chemotherapy, if possible. Partial(more than 50% reduction of tumor mass) response at 15+ to 47+ weeks after chemotherapy was noted in three(60%) of the five patients with recurrent oligodendrogliomas. But in patients with recurrent anaplastic astrocytoma or glioblastoma, partial response at 8+ weeks after chemotherapy was noted in one(14%) of the seven patients. It is suggested that PCV chemotherapy is more effective for patients with recurrent oligodendrogliomas than other recurrent gliomas.

Fracture involving the sella turcica is a rare complication of head injury but draws attention of neurosurgeon because it can result in serious neurological, vascular and endocrine complications. Anatomically the sella being located central within the extensive basal dural attachments to the cranial vault, shearing force is transmitted directly to this structure and results in isolated compications. We recently experienced a case of fractured dorsum sellae complicated with cranial nerve palsy and report here with some references,

Direct exposure to toxic and hazardous gases has always been considered as the most pervasive problem worldwide, leading to a gradual increase in the number of asthma patients due to NOx/SOx gases inhaling and exposure to 50 ppm formaldehyde gases. Therefore, the development of accurate gas sensors is a key issue for resolving these problems. To address such issues, the development of membranes for selective filtering of target molecules as well as nanocatalyst for enhancing the sensing selectivity is highly crucial. In this review, the research progress for porous membrane materials (e.g. MOFs, and graphene) and nanocatalyst technology for the development of selective and accurate gas sensors will be discussed.

Purpose: This prospective study evaluated the effects of continuous sedation using midazolam, with or without remifentanil, on postoperative nausea and vomiting (PONV) in patients undergoing myringoplasty. Materials and Methods: Sixty patients undergoing myringoplasty were sedated with midazolam in the presence of remifentanil (group MR), or after saline injection instead of remifentanil (group M). Results: Three patients (10%) in group M complained of nausea; two vomited. Four patients (13%) in group MR complained of nausea and vomited within 24 h after surgery. Rescue drugs were given to the six patients who vomited. No significant difference was detected between the two groups regarding the incidence or severity of nausea, incidence of vomiting, or need for rescue drugs. Conclusion: Midazolam-based continuous sedation can reduce PONV after myringoplasty. Compared with midazolam alone, midazolam with remifentanil produced no difference in the incidence or severity of nausea, incidence of vomiting, or need for rescue drugs.

As operations that were only conducted in physical space in the past change to operations that include cyberspace, it is necessary to analyze how cyber attacks affect weapon systems using cyber systems. For this purpose, it would be meaningful to analyze a tool that analyzes the effects of physical weapon systems in connection with cyber. The ROK military has secured and is operating the US JMEM, which contains the results of analyzing the effects of physical weapon systems. JMEM is applied only to conventional weapon systems, so it is impossible to analyze the impact of cyber weapon systems. In this study, based on the previously conducted cyber attack damage assessment framework, a framework for analyzing the impact of cyber attacks on physical missions was presented. To this end, based on the MOE and MOP of physical warfare, a cyber index for the analysis of cyber weapon system effectiveness was calculated. In addition, in conjunction with JMEM, which is used as a weapon system effect manual in physical operations, a framework was designed and tested to determine the mission impact by comparing and analyzing the results of the battle in cyberspace with the effects of physical operations. In order to prove the proposed framework, we analyzed and designed operational scenarios through domestic and foreign military manuals and previous studies, defined assets, and conducted experiments. As a result of the experiment, the larger the decrease in the cyber mission effect value, the greater the effect on physical operations. It can be used to predict the impact of physical operations caused by cyber attacks in various operations, and it will help the battlefield commander to make quick decisions.

Objective:The authors describe four patients in whom we performed a single stage, pedicle subtraction and extension wedge osteotomy for the correction of sagittal imbalance by creating lumbar lordosis. Methods:One patient presented with congenital hemivertebra, one with post-laminectomy kyphosis, and two with lumbar degenerative kyphosis. All patients suffered from back pain and were unable to walk due to forward stooping of the trunk. We performed a single stage, pedicle subtraction and extension wedge osteotomy for the correction of sagittal imbalance. Results:The angles of correction were 37, 44, 45, and 49 degrees. No case had any neurologic complication. All patients reported complete relief of back pain and were able to upright standing. Conclusion:Single-level wedge osteotomy and reduction provide excellent sagittal correction of rigid kyphotic deformities in the lumbar lesion without neurologic compromise. Key words:Fixed kyphotic deformity;Pedicle subtraction and extension wedge osteotomy.
