Nonconvulsive status epilepticus (NCSE) is an unusual complication in patients treated with cefepime. An 82-year-old woman on maintenance hemodialysis was given cefepime for pneumonia. Her level of consciousness decreased since the administration of cefepime, and she was diagnosed with NCSE based on electroencephalography (EEG) findings. After discontinuation of cefepime, improvement was seen both in the level of consciousness and EEG findings. Clinicians should be aware of cefepime-induced NCSE, particularly in patients with renal failure.

The purpose of this study was to explore the relationship between burden and burnout of the family care-givers for caring of terminal patients with cancer. A total of 99 convenience sample was recruited form hospitals. The data were collected by a direct interview with Questionnaire about family burden and burnout. The mean score of burnout of main care-givers was 2.98, and the mean score of burden was 3.03. The care-givers' burnout was significantly different by age, sex, job, duration of treatment, level of acceptance on the stage of death, and ability of daily living activities. The family care-givers' burden was significantly different by the jobs, complication of patients, level of acceptance on the stage of death, and ability of daily living activities. In conclusions, the burnout of family care-givers was highly and positively correlated with the burden.

The common carotid artery generally bifurcates into the internal and external carotid arteries at the level of C3-4. Injury to the common carotid artery during anterior cervical discectomy is a complication that is very much feared but encountered rarely. Knowing the anatomic variations of the common carotid artery and using an operating microscope during the anterior cervical approach for cases with low-lying bifurcation of the common carotid artery would prevent injuries to this artery. We present a 42-year-old female who has successfully undergone anterior cervical discectomy at the level of C5-6 and C6-7. She had a low-lying bifurcation of the common carotid artery.

Spontaneous cerebrospinal fluid (CSF) leak is a recognized cause of spontaneous intracranial hypotension (SIH). Subdural hematoma (SDH) is a serious but rare complication of SIH. An autologous epidural blood patch at the CSF-leak site can effectively relieve SIH. We report a case of bilateral SDH with SIH caused by a CSF leak originating at the C1-2 level. A 55-year-old male complained of orthostatic headache without neurological signs. His symptoms did not respond to conservative treatments including bed rest, hydration and analgesics. Magnetic resonance imaging showed a subdural hematoma in the bilateral fronto-parietal region, and computed tomography (CT) myelography showed a CSF leak originating at the C1-2 level. The patient underwent successful treatment with a CT-guided epidural blood patch at the CSF-leak site after trephination for bilateral SDH.

Purpose: Congenital factor VII (FVII) deficiency is a rare bleeding disorder and surgery can cause excessive bleeding due to an extrinsic pathway problem. It can be diagnosed by increased PT and decreased FVII level in coagulation test. Symptom varies according to the level of FVII, but it is essential to prevent intraoperative excessive bleeding. Methods: In this report, we described the orthognatic surgery experience in a mandibular prognathism patient with congenital FVII deficiency, in which recombinant activated factor VII (rFVIIa) was used to manage the bleeding. Rsults: We could get a successful result without any complication and there was minimal intraoperative bleeding. Conclusion: The orthognathic surgery could therefore be safely performed in patients with congenital factor VII deficiency using rFVIIa.

The purpose of this case report is to describe a rare case of a cervicothoracic spinal epidural hematoma (SEH) after anterior cervical spine surgery. A 60-year-old man complained of severe neck and arm pain 4 hours after anterior cervical discectomy and fusion at the C5-6 level. Magnetic resonance imaging revealed a postoperative SEH extending from C1 to T4. Direct hemostasis and drainage of loculated hematoma at the C5-6 level completely improved the patient's condition. When a patient complains of severe neck and/or arm pain after anterior cervical spinal surgery, though rare, the possibility of a postoperative SEH extending to non-decompressed, adjacent levels should be considered as with our case.

A 22 year old soldier was discovered on routine study for discharge to have a mass in the posterior mediastinum He was admitted due to high fever and improved by antibiotic treatment for 2 weeks. Chest PA, apicogram, myelogram and CT scan demonstrated enlargement of the neural foramen at the T1 level with erosion of the posterior aspect of the vertebral body and the pedicle contiguous with the intrathoracic mass, A myelogram showed a large extradural defect at the T1 level on the left. There were no clinical signs of cord compression. A standard posterolateral thoracotomy incision was made with extension to high thoracic vertebra. The 3rd rib was resected and the angles of the posterior portion of 1st and 2nd ribs were cut and rib heads were removed. Extrapleural neurilemmoma 6x6 cm was resected intrathoracically. And after removal of the pedicle and the lamina, intraspinal extradural mass 3 X 2 cm was resected carefully with trivial tearing of the dura which was sealed with gel-foam and pleura. There was ma postoperative neurological complication.

Purpose: The purpose of the study was to investigate the level of smoking, process of smoking cessation, and nicotine dependency, and urine nicotine among adults with diabetes which are smokers and to examine the relationship among those variables. Method: The subjects consisted of 62 adult men smokers with diabetes mellitus. FTQ and NicCheck 1 were used to measure the level of nicotine dependence. The amount of cigarette smoking was measured by the number of cigarette packs use per week. The stage of smoking cessation was measured by the Prochaska's method. Results: The Subjects smoked cigarettes with a mean of 5.97 packages per week. Seventy-seven percent of the subjects had a nicotine dependency. Fifty-two percent had a high level of nicotine dependency in urine nicotine. Nineteen percent were in the precontemplation stage. The level of cigarette consumption was related to nicotine dependence and urine nicotine. Also, nicotine dependency was related to urine nicotine. Conclusion: A tailored smoking cessation program is needed to prevent the chronic complication for diabetes smokers. Self-reported smoking and nicotine dependency seemed to do equally well as NicCheck 1 in assessing nicotine intake.

Even though, tanks are used at the many industry plants, it is very difficult to control the tank level without any overflow and shortage; moreover, cause of its complication of dynamics and nonlinearity, it's impossible to realize the accurate control using the mathematical model which can be applied to the various operation modes. However, the sliding mode controller(SMC) is known as having the robust variable structures for the nonlinear control systems with the parametric perturbations and with the sudden disturbances. It's difficult to find SMC's parameters, and SMC is bring chattering which injures actuator and increases error. In this paper, Genetic Aloglism based Fuzzy Sliding Mode Controller(GA-FSMC) for the precise control of the coupled tank level was proposed. Genetic Algolism and Fuzzy logic are adapted to find SMC's parameters and reduce the chattering. The simulation result is shown that the tank level could be satisfactorily controlled with less overshoot and steady-state error by the proposed GA-FSMC.

Perforation of maxillary sinus is a common complication of implant placement in posterior maxilla. The purpose of this study was to evaluate the prognosis of sinus perforated implants placed in partially edentulous maxillae. Eighteen sinus perforated implants in 15 patients were examined for cumulative survival rate, radiographic preoperative bone level, and radiographic marginal bone level change. Twenty-two non-perforated implants in the same patients served as control. The results were as follows; 1. There was no statistically significant difference in cumulative survival rate between sinus perforated implants and non-perforated implants (P>0.05). 2. There was no statistically significant difference in the marginal bone level between sinus perforated implants and non-perforated implants (P>0.05). 3. There was no statistically significant difference in cumulative survival rate according to the preoperative bone level (P>0.05). These results suggests that perforation of maxillary sinus may not affect implant success in posterior maxillae.
