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.

PURPOSE: The voiding difficulty in aged people is usually caused by prostate tumor and these tumors are influenced by the androgen. The purpose of this research was to study the prostatic genetic change caused by changes of hormonal mileu and evaluate the pattern of the changes of p57 and bcl-2 mRNA in human and rat prostate at different biological condition. MATERIALS AND METHODS: This study was performed in two ways, with animal model and human prostate. As animal model, the rats were castrated surgically or chemically(5-alpha reductase inhibitor) and their prostates were collected according to the schedule. Pattern of expression changes in p57 and bcl-2 mRNA was observed. In human prostate, three normal prostates from young 30th, five benign hyperplastic prostates and five cancerous prostates were collected for evaluation of p57 mRNA expression. The evaluation of the expression of those genes was done by in situ hybridization. RESULTS: The expression of the p57 mRNA was observed at the cytoplasm in all three types of the prostate tissues. The expressions of mRNA message were increased from the post-orchiectomy three days group up to postorchiectomy two weeks. After two weeks, there were little change in expression of the p57 mRNA. Compared with normal prostate group, the expressions of p57 mRNA were reduced in BPH and prostate cancer groups without treatment. The expression of bcl-2 was increased in expression upto postorchiectomy 4th week and reduced. In BPH and prostate cancer, the expression of the bcl-2 mRNA was increased in comparison with normal prostate. CONCLUSIONS: With above experiment, the expression patterns of p57 and bcl-2 mRNAs reversed and the prostate cancer showed reduced expression. This result suggests that p57 and bcl-2 may play important roles in differentiation of BPH and prostatic cancer. The differentiation of BPH and prostate cancer by p57 and bcl-2 were impossible.

Pseudomonas scleral abscess is characterized by acute onset and rapid progression to scleral perforation, and has a subsequent risk of endophthalmitis. After control of infection with appropriate antibiotics, graft surgery should be performed for reinforcing the defected sclera. We performed a scleral homograft on the eye with large necrotic sclera caused by Pseudomonas aeruginosa infection after pterygium excisIon. And the results were remarkably good.
