Malignant leptomeningeal metastases involving both internal auditory canals (IACs) are rare and can mimic neurofibromatosis type 2 (NF2). Rapid progression of symptoms and involvement of facial nerve are characteristic clinical courses in contrast to the slow progression of symptoms in NF2. We report a rare case suspected to be metastatic tumor involving bilateral IACs, and presenting sudden bilateral hearing loss in a patient who was previously treated for adenocarcinoma of lung.

Obstructive jaundice by vascular compression is rare. The causative arteries were identified as the right hepatic artery, gastroduodenal artery, cystic artery, proper hepatic artery, and an unspecified branch of the common hepatic artery. Also the venous system, such as enlarging collateral veins in cases of portal hypertension was a causative vessel. Herein, we describe a case of a proximal choledocholithiasis due to compression of the common bile duct by right hepatic artery originated from gastroduodenal artery. Final diagnosis and treatment were achieved through an operation.

BACKGROUND/AIMS: Propofol is usually used for anesthesia in the case of day surgery. We studied the effects of propofol plus fentanyl for sedation and the effect of oxygenation during gastroscopy. METHODS: 154 patients who asked conscious sedation during gastroscopy were randomly divided into three groups. The first group (PF-O group, 50 patients) and the second group (PF group, 48 patients) were received an initial bolus dose of propofol (40 mg) plus fentanyl (50 microgram) intravenously, followed by additional doses of propofol at one minute interval until conscious sedation. PF-O group was received preoxygenation (3 L/min) via nasal canula, and PF group was not. The third group (56 patients) received an initial bolus dose of midazolam (3 mg) intravenously, followed by additional doses of midazolam at two minutes interval (M group). RESULTS: In PF-O group, time to achieve sedation, regain orientation, and recover walking ability were 118.0 85.2 sec, 67.5 91.2 sec and 11.1 5.3 min. Gag reflex during the procedure was absent or nearly absent in 96% of patients. Despite the changes of blood pressure and heart rate compared to the values taken prior to the procedures were observed, all values were not clinically significant. In PF-O group, transient oxygen desaturation (SaO2<90%) was observed in four (8.0%) patients. CONCLUSIONS: Propofol plus fentanyl with oxygenation seems to be more acceptable and suitable method for sedation during outpatient gastroscopic examination.

Microinvasive carcinoma of the uterine cervix(FIGO stage IA) has been reported as highly curable disease even with conservative surgery such as conization and simple hysterectomy. Nevertheless, the surgical management for microinvasive carcinomas has been proposed varying from conservative surgery to radical hysterectomy with pelvic nodes dissection according to different diagnostic criterias for microinvasive carcinoma. We reviewed 512 patients who had been diagnosed as microinvasive carcinoma of the uterine cervix at the Department of Obstetrics and Gynecology, Samsung Cheil Hospital and Women's Healthcare Center from Jan. 1988 to Dec. 1995. Among them, 376 patients were included in this study satisfying guided criterias such as proper management and follow up more than at least one year, and they were analyzed retrospectively based on the clinicopathologic characteristics, pattern of surgical management and postoperative status.

OBJECTIVES: This study was performed to analyze the factors that affect the decision to approve workers compensation claims for cerebrovascular and cardiovascular diseases and to analyze the worker characteristics. METHODS: Three hundred, sixty-nine cases were collected based on the workers compensation records of three Seoul and Incheon Regional centers of the Labor Welfare Corporation between 1998 and 1999. They contained the general characteristics, injury information and past medical histories. The x2-test and logistic regression were performed to investigate the factors affecting the approvals. Seventy-two survivors were surveyed by telephone for job stress. Job stress was surveyed in three parts: job demands, decision latitude and personal free time. RESULTS: Of the cases, 167 obtained approval from the Corporation; the others did not. Regardless of approval, 62% of all subjects had more than one of the cerebral and cardiovascular risk factors. Especially, 53.9% of subjects had hypertension. According to the logistic regression, the fatal cases had a higher approval rate (OR=26.4, CI=9.13-76.22). The cases with working condition change (OR=6.5, CI=3.45-12.07), accidents on worksite (OR=4.9, CI=2.39-10.07), female (OR=4.0, CI=1.21-13.3), accidents at night duty (OR=2.9, CI=.156-5.39), cases occurring on duty (OR=.25, CI=1.34-4.72) and cases without past disease history (OR=1.8, CI=1.02-3.36) also had higher approval rates. Telephone survey found that the approval rate increased with decreasing freedom of personal time schedule. However, the logistic regression revealed that job stress didnt affect the approvals. CONCLUSION: To prevent cerebrovascular and cardiovascular diseases, the most important aspect is to control hypertension which is the most common risk factor among the victims. Moreover, job stress and over working should be considered in the just approval of the workers compensation claims.

BACKGROUND AND OBJECTIVES: This study was done to evaluate the safety of Gore-Tex as a nasal implant. Materials and METHOD: A retrospective multicenter study was carried out on 15 surgeons from 11 general hospitals and 4 private practice clinics regarding the safety of the Gore-Tex as a nasal implant. The study involved 853 patients, of whom 656 received primary surgery and 197 revision surgery. Gore-Tex was mainly used as a dorsal implant in a form of sheet or as a reinforced nasal implant. RESULTS: The overall complication rate associated with Gore-Tex was 2.5% (21 cases). Infection was the most common complication (18 cases ; 2.1%) followed by 2 cases of seroma and 1 case of persistent nasal swelling. In 19 out of 21 complication cases, the graft needed removal to control the infection or seroma (91% removal rate). Nine cases of infection developed in both primary cases (1.37%) and in revision cases (4.57%), which suggests a higher association rate between infection and revision cases (p=0.0062). Infection developed within 1 month in 5 cases while 9 cases developed infection after 6 months of operation. Other complications such as aesthetic problems (malpositioning of the implant or dorsal irregularities) were found in 15 cases (1.8%) and hematoma in 1 case. CONCLUSION: The infection rate of Gore-Tex used in rhinoplasty was about 2% and it rose significantly in the revision cases. If infected, almost all of the implanted Gore-Tex needs removal; therefore, we suggest judicious use of Gore-Tex in rhinoplasty.
