PURPOSE: To evaluate tlne significance of vaginal air seen on CT scan in preoperative staging of uterine cervical carcinoma. METHODS AND MATERIALS: A comparison was made between CT findings of vaginal air and true vaginal involvement status in 85 patients with uterine cervical carcinoma. CT findings were analyzed in terms of the presence or absence of vaginal air, number of CT slices in which vaginal air was seen, shape of vaginal air, and relation of vaginal airto cervical mass. RESULTS: Vaginal air was present in 35 patients and was absent in 50. Although the mere presence of vaginal air or multiplicity of CT slices showing vaginal air did not signify the presence of vaginal involvement, vaginal air with irregular margin or vaginal air adjacent to uterine cervical mass was suggestive of vaginal involvement. CONCELUSION: These observation of vaginal air in interpreting CT may be helpful in the preoperative staging of uterine cervical carcinoma.

BACKGROUND: A fully automated enzyme-immunoassay (EIA) analyzer, Enzymun System, ES-300 (Boehringer Mannheim, Germany) uses streptavidin technology and performs single test or panels of up to 12 tests per run. We evaluated the results of ES-300 for anti-HCV by comparing the results with microplate-EIA, radioimmunoassay (RIA), and confirmatory test. METHODS: Total 79 sera (51 positive, 24 negative, 4 indeterminate results confirmed by Lucky HCD Confirm) were analysed. ES-300 with Enzymun-Test(R) Anti-HCV (Boehringer Mannheim, Germany) and microplate-EIA (Green Cross Center Innotest HCV 3.0(R)) were used. Fifty one sera were examined additionally by 2nd-generation RIA method, NANBDINE 125C(General Biologicals Corp., R.O.C.). And all results were compared to the results of Lucky HCD Confirm. RESULTS: The overall concordance rate of ES-300 and Innotest(R) was 72/79 (91.1%). The results of Lucky HCD Confirm on seven discrepant samples were five negative and two indeterminate. The results of ES-300 and NANBDINE 125C showed concordance rate of 90.2%. The sensitivity and specificity of ES-300 with regard to Lucky HCD Confirm were 94.5%, and 87.5%, respectively, and that of Innotest(R) were 98.2% and 66.7%, respectively. Clear distinction of positive and negative results by signal/cut off ratio was available in both EIAs. The positive predictive values of ES-300 and Innotest(R) were 94.5%, and 87.1%, respectively. CONCLUSIONS: ES-300 showed relatively good results in sensitivity and positive predictive value with regard to confirmatory test. In EIA-positive persons, however, follow-up study would be necessary for reliable evaluation of HCV infection.

Transcatheter arterial embolization was applied in 7 cases of hepatic disease including hemobilia of various causes and malignant tumors at Department of Radiology, Seoul National University Hospital during recent several years. The embolic materials were autologous blood clot and Gelfoam particle. Successful control of bleeding or devascularization of tumor vessel was made in 6 of the 7 patients. There was no serious complications; however, post embolization syndrome was found including pain, fever, nausea and vomiting in all cases and subsided after a few days. Transcatheter hepatic arterial embolization is suggested to be a safe and effective treatment in control of hemobilia and devascularization of malignant hepatic tumors.

The frequency of stab wounds is gradually increasing and patients with stab wounds visit the hospital through the emergency room. Management options for patients with stab wound include mandatory exploration and selective observation, but recently many authors have emphasized the importance of selective conservation with development of diagnostic procedure and controversy still exists concerning the management of patients with stab wounds. We retrospectively analysed the clinical data of 78 patients with stab wounds who visited the emergency room of St. Paul's Hospital over 5 years from January 1 1992 to December 31 1996. The following results were obtained. 1) The most prevalent age group were the twenties & the thirties(58.9% of patient) and then most patients were of young age. The male to female ratio was 2.9: 1. 2) Most injuries occurred at night between 8p.m. and 4a.m.(61.5%) and during September injuries were most frequent. 3) The most common causes of stab wound were fighting(55.1%) followed by suicide (21.8%), then accidents including traffic accidents(16.7%) and robbery(6.4%). 4) The instruments most commonly used were knives(53.8%) and broken glass(28.2%). 5) Half of patients were drunk from alcohol and in 3 cases from an antipsychotic drug. 6) In 11 cases(14.1%), there were multiple wound sites and in 8 cases(10.3%) superficial wounds into subcutaneous fatty tissue. 7) According to stab wound sites, the extremities were wounded in 36 cases(46.2%), chest in 21 cases(26.9%), abdomen in 15 cases(19.2%) and neck in 7 cases(9.0%). 8) Emergency explorations were performed in 43 cases(55.1%) under general or regional anesthesia, which included neck in 4 cases(9.3%), chest in 3 cases(7.0%), abdomen in 11 cases(25.6%) and extremity in 25 cases(58.1%). In exploratory laparotomy, negative exploration rate was 18.2%. 9) Death occurred in 2 cases(2.6%). One died due to sepsis with multiple colon perforation and the other due to hypovolemic shock with Superior Vena Cava injury.

OBJECTIVES: This study was conducted in order to evaluate the effects of inhalants on color vision impairment. METHODS: The inhalation group consisted of 81 neurotoxic chemical substance abusers at Bugok National Hospital and Institute of Forensic Psychiatry, Ministry of Justice. The control group consisted of 41 employees of Bugok National Hospital. The Lanthony D-15 desaturated hue test was administered to both groups. For the qualitative analysis, we classified the results by the morphological characteristics of color vision impairment. For the quantitative analysis, we calculated the total color distance score (TCDS) and the color confusion index (CCI) and determined that the individual was abnormal if the TCDS was over 65.0 or the CCI was over 1.25. RESULTS: The TCDS of the inhalation group was 75.58+/-21.07 and the CCI was 1.34+/-0.37 in the right eye, and 75.47+/-23.63 and 1.34+/-0.42, respectively in the left eye. These results are higher than those found for the control group. In regards to the TCDS, 50 (61.8%) of the abusers in the inhalation group had color vision impairment in the right eye and 48 (59.2%) had impairment in the left eye. 11 (26.8%) of the employees in the control group had color vision impairment in the right eye and 13 (31.7%) had impairment in the left eye. In regards to the CCI, 38 (46.9%) of the abusers in the inhalation group had color vision impairment in the right eye and 35 (43.2%) had impairment in the left eye. 4 (9.8%) of the employees in the control group had color vision impairment in the right eye and 7 (17.0%) had impairment in the left eye. The results of multiple logistic regression analysis for acquired color vision impairment showed that the inhalation period (OR=1.20, 95% CI: 1.03~1.40) was the significant variable. CONCLUSIONS: These findings indicate that the inhalation of neurotoxic substances may impair the color vision, and the period inhaled with neurotoxic substances is significant variable affecting on the acquired color vision impairment.

A 56 year old female patient was found to have a lung mass in the right upper lobe lobe during evaluation for cough and sputum. The mass had grown slightly over the past 6 months when she was admitted for an operation. Preoperative studies revealed the benign nature of the tumor, and a thoracoscopic right upper lobectomy was performed. Postoperatively, the diagnosis was histologically proven to be pulmonary leiomyoma which is a rare type of benign lung tumor.

Though intravenous digital subtraction angiography (IV DSA) has several advantages over conventionalangiography in diagnosis and follow up of various vascular disease, it also has several undesirable problems suchas large volume of the contrast medium and inferior image quality compared to conventional angiography. Sorecently intraarterial digital subtraction angiography (IA DSA) was introduced for better image quality usingsmall amount of contrast medium. The authours had good clinical results IA DSA which were made in 20 patients withour own system, SRM-II, developed by cooperation of Departements of Radiology and Medical engineering, Seoul.National University Hospital. Intraarterial digital substraction angiography was found to have several advantagesover conventional angiography: (a) small amount of contrast medium, (b) reduced need for selective arterialcatheterization,(c) lower film cost, (d) shortened examination time, (e) ability to obtain a “road map”, and (f)easier detection of contrast medium. Also IA DSA has several advantages over IV DSA : (a) less dependency oncardiac output, (b) far less vessel overlapping, (c) reduction in patient motion through less painful procedure byreduced volume of contrast media and shorter imaging time.

The lung nodule is one of the pleuropulmonary menifestations in rheumatoid arthritis. We report here a case exhibiting hydropneumothorax due to a bronchoplerual fistula resulting from a ruptured rheumatoid lung nodule complicated with a aspergilloma in it. A 39 year-old man with rheumatoid arthritis was admitted because of cough for one month. Multiple subcutaneous nodules were noted and multiple lung nodules were seen on chest X-ray, Peripheral white cells were 9,600/mm3 with 1896 of eosinophils. The percutaneous needle aspiration biopsy of the largest lung nodule of right upper lobe showed massive necrosis without acid fast bacillus, fungus, or malignant cell. Three months after discharge, air-meniscus sign was seen on the biopsied lung nodule on X-ray. Five months later, the patient was readmitted due to dyspnea and chest pain and simple chest X-ray showed hydropneumothorax on the right side. The pneumothorax was not healed after closed thoracotomy and tube drainage, and high fever developed. The pleural fluid culture revealed Pseudomonas aeroginosa and Aspergillus fumigatus. Seventy days after admission, exploratory thoracotomy was done. Aspergilloma was found in the cavitated lung nodule which was ruptured into the pleural cavity through bronchopleural fistula.

When performing septoplasty in patients with a high deviation of the nasal septum, effective correction is difficult and postoperative complications such as a saddle nose may result if the bone or cartilage is removed inordinately. Although several surgical techniques have been introduced, some are difficult to apply easily. Furthermore, the deviation may persist despite the application of surgical techniques due to the rebound memory of the remaining cartilage. This study aimed to describe a simple and safe surgical technique for crooked nasal septa with a high deviation. This method using horizontal dorsal septal incision allows easy separation of the highly deviated portion from the upper lateral cartilage. Furthermore, it is less traumatic than other methods, and predictably preserves the keystone area.

BACKGROUND AND OBJECTIVES: Heat shock proteins (HSPs) are group of evolutionary conserved proteins whose synthesis are greatly enhanced in cells following exposure to various stressors and play an important role in cellular protection and survival. The purpose of this study was to determine whether olfactory stimulation induces the synthesis of HSP72 in olfactory system of the rat. MATERIALS AND METHODS: Animals were exposed to odorant stimuli using 2% propionic acid odorant stimuli and expression pattern of HSP72 in the olfactory system were detected by immunohistochemistry using anti-HSP72 antibody according to time course and by Western blotting. RESULTS: HSP72 immunopositive cells were expressed in the olfactory epithelium and in the olfactory bulb neurons and a 72 kD band was detected by Western blotting. CONCLUSION: These results suggest that expression of HSP72 in olfactory system of the rat following exposure to odor may serve as a marker for cellular stress and potential damage and may be involved in cellular protection against injuries.
