The use of intravacular catheterization for both diagnostic and therapeutic purposes increased the incidence of iatrogenic foreign bodies, which might cause many complications such as cardiac arrythmias, perforation of cardiac chamber or blood vessels, sepsis and thromboembolism. The authors experienced 5 cases of successful retrieval of intravascular iatrogenic foreign bodies: three cases of subclavian catheter wire and two cases of subclavian catheter. Subclavian catheter was introduced into right subclavian venous route for hyperalimentation or central venous pressure monitoring. The foreign bodies were located in superior vena cava and inferior vena in four cases and in left main pulmonary artery in the other case. We have successufully removed the foreign bodies by interventional procedures. The loop-snare technique is a safe and effective method for retrieval of iatrogenic foreign bodies in great vessels.

Chest CT is the most useful modality in the diagnosis of primary lung cancer, particularly in patients with recurrent pneumonia which are resistant to antibiotic therapy and in high risk age groups for cancer, The purpose of this examination is to assess the usefulness of CT in pneumonia types of lung cancer. The authors retrospectively analyzed 15 histologically proven cases of pneumonic type lung cancer, which had no evidence of primary lung mass, mediastinal lymphadenopathy or other metastatic lesion on piain chest radiography. On CT scan, a primary lung mass was identified in 13 patients(87%, bronchial obstruction was identified in 12 patients(80%), and metastatic foci was found in the bone(one patient), liver(one patient), and spleen(one patients). In Conclusion, CT scan is a useful method to detect the mediastinal lymphadenopathy or pulmonary mass and also should be the initial radiolographic procedure for diagnosis of lung cancer in patients with recurrent pneumonia on simple chest radiography.

Intraspinal neurenteric cysts are rare congenital lesions that results from abnormal separation of germ layers in the third week of embryonic development, which may cause spinal compression. Although, the diagnosis of neurenteric cyst was very difficult prior to operation, MRI has proven to be a useful imaging modality in detection, localization and characterization of intraspinal neurenteric cysts. We recently experienced intraspinal neurenteric cyst in two patients who presented with progerssive quadriparesis. Myelography, CT myelography and MRI were taken and complete excision was performed. The MRI findings are presented and the literature is reviewed.

PURPOSE: The purpose of this study is to describe Magnetic Resonance(MR) findings of two epidural cavernous malformations of the spine. MATERIALS AND METHODS: MR imaging was performed in 2 patients(29-year-old man and 54-year-old woman). Sagittal T1 -, T2-weighted images and Gadolinium (Gd)-enhanced axial and sagittal images were acquired. Two patients had surgery and MR findings were compared with surgical and histopathological findings. RESULTS: MR imaging showed high- and low-signal intensity components of these lesions that were characteristic of an epidural cavernous malformation in one case. The other case showed a high signal intensity on T2- and strong enhancement on Gd-enhanced T1 -weighted images. We think that the former may be due to mixed subacute and chronic hemorrhage and the latter may be due to blood within the endotheliumlined sinusolds without hemorrhage. CONCLUSION: These findings were well correlated with the surgical and histo-pathological findings of cavernous malformation.

In an outpatient setting, 107 patients were evaluated using a single 24-hour specimen with StoneRisk Diagnostic Profile on a random diet before medication and treatment and updated the classification of nephrolithiasis. For specific subclassification of hypercalciuric calcium(Ca) nephrolithiasis, calcium and sodium restricted diet and sodium cellulose phosphate screening test were underwent. Abnormal urinary biochemistry was classified into one or more of 20 etiologic categories. A single diagnosis was documented in 37(34.6%) patients and the remaining 65.4% had more than one diagnosis. Hypercalciuric Ca nephrolithiasis occurred in 41 (38.3%) patients and specific subclassification of 6 variants was performed. In this study, hypercalciuric Ca nephrolithiasis occurred less frequently in comparison to the incidence of U.S.A. reported by Dr. Pak. Hyperuricosuric Ca nephrolithiasis (HUCN) and gouty diathesis(GD) accounted for 47(43.9%) and 8(7.4%) patients, respectively. Hyperoxaluric Ca nephrolithiasis was in 25(23.4%) patients and all were dietary origin following an oxalate-restricted diet. Hypocitraturic Ca nephrolithiasis was seen in 51(47.6%) patients in idiopathic variant. Hypocitraturia due to RTA and chronic diarrheal syndrome occurred in 1(0.9%) and 2(1.8%) patients. Hypomagnesiuric Ca nephrolithiasis and acquired problem of low urine volume(<1 L/d) were accounted in 3(2.8%) and 13(12.2%) patients, respectively. Infection stones or cystinuria were not detected. No metabolic abnormality was found in 12(11.2%) patients. High sodium take was detected in 60(56.1%) patients, reflecting that Koreans take high sodium containing foods. We think that StoneRisk Diagnostic Profile using a single 24-hour urine specimen is very useful in detecting stone-forming risk factors and providing specific therapeutic guidelines. Additionally, recurrence associated with high cost of medical care can be reduced through adequate diagnostic evaluation as part of the treatment regimen.

CTDs have been a growing problems for US and European industries with higher incidence rate every year. In our country, we have just Started to recognize and to work on the problems in industry. In this respect, this would be the first ergonomic-based CTD study with medical data. Two automobile part plants were ergonomically and clinically surveyed for this study. Specifically,' 25 jobs from A industry and 51 jobs from B industry were matched with the clinical data. Two types of analysis were conducted. First, ergonomic job evaluation using CTD checklist was done for both industries to figure out the relative risks for each jobs. Second, comprehensive analysis for risk factors regarding CTDs was conducted. It produced mainly two results. First, multiple regression analysis of both worker and work-related factors on total scores based on the results of the'physical examination showed that there was no statistically significant relationships between total scores based on physical examinations and either worker or work-related risk factors. Second, logistic analyses for both factors were done. An user-friendly logistic program was developed for this analysis and for the future analysis of CTD study in the long-run. The program would have even non-expert in statistical package easily manipulate logistic analysis. Based on the logistic analysis, there was no significant relationships between worker related risk factors and all CTD types except marital status. However, there was some significant results in terms of work-related factors. Lateral pinch and ulnar deviations had significant relationship with both all CTD types and CTS. Power grip was associated with all types of CTDs, Tendinitis and Carpal Tunnel Syndrome. The cycle time had significant effects only on Carpal Tunnel Syndrome. In conclusion, the first ergonomic-based CTD study has been initiated in Korea. However, it was realized that good overall situation for CTD study in Korea has been before the right time yet. Therefore, futher research on the basis of the framework of this study is strongly suggested to have a complete CTD guidelines in the near future.

Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/non- neoplastic lesions in fifty-three cases and failed in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion, diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.
