BACKGROUND & OBJECTIVE: Recent studies suggest that anticoagulation, or antiplatelet therapy is safe and effective for the prevention of cardiogenic embolic stroke. However it has not been studied in Korea how the patients with cardioembolic source were managed in practice for the prevention of stroke. This study was done to assess the current status of primary and secondary prevention of cardioembolic stroke. METHODS: Retrospective study was undertaken in 124 patients with cardiogenic embolic stroke, following items were examined, previous anticoagulation or antiplatelet therapy, previous stroke, Insight of the heart disease, and International Normalize Ratio(INR) value on arrival at the hospital. RESULTS: In 124 patients cardioembolic sources were constituted of non-valvular atrial fibrillation (NVAF) in 54, rheumatic heart disease In 40, prosthetic cardiac valve In 14, dilated cardiomyopathy(D-CMP) in 6, left ventricular akinetic segment in 7(including 3 cases of LV thrombi), recent myocardial infarction in 3. In 93 patients with no previous stroke, 44 patients had regular medical follow-up because of his/her cardiac problems and primary prevention of stroke was made only in 12 (27%) patients (8 on anticoagulation and 4 on antiplatelet therapy). The rate of primary prevention varied according to the type of cardioembolic source; 100% with mechanical prosthetic valve, 33.3% with valvular atrial fibrillation, 6.7% with NVAF, and none with D-CMP and bioprosthetic valve. Previous stroke was found in 31 patients, among whom 24 had been followed regularly. Twenty patients(83%) were under secondary prevention of cardioembolic stroke (anticoagulation in 11 and antiplatelet agents in 9). Among 19 patients who developed stroke in spite of anticoagulation, INR values were lower than 1.5 in 12(63%), between 1.5 and 2.0 in 5(26%), and above 2.0 in 2(11%). CONCLUSION: Our results suggest that cardioembolic strokes have not been prevented properly. Many physicians seem to be reluctant to anticoagulate their patients with cardioembolic source, and even with anticoaguation the dosage is frequently insufficient to prevent stroke.

The Mainz classification for renal cell tumors was introduced in 1986 and it's utility has been reported in several histogenetic and genetic studies of renal cell tumors. We present a study of 127 cases of renal cell tumors with clinicopathologic correlation, DNA content analysis, and histogenesis studied by histochemical and immunohistochemical staining. The 127 renal cell tumors classified by the Mainz classification were 87 clear cell, 17 chromophilic, 13 chromophobe and 3 sarcomatoid renal cell carcinomas, 5 oncocytomas and 2 adenomas. These subtypes showed significant correlation not with age, sex, Robson's stage, DNA ploidy or tumor recurrence but with nuclear grade (p=0.001) and tumor size (p=0.001). Hall's colloidal iron (p=0.002) and carbonic anhydrase II (p=0.013) stains, representing the origin of distal nephron especially of collecting duct, were significantly correlated with specific subtypes of renal cell tumors, especially chromophobe cell renal carcinoma. This study demonstrates that the Mainz classification suggests several morphologically different subtypes and variants of renal cell tumors and that some of them may have originated from the distal nephron, particularly from the collecting duct.

Listeria monocytogenes is a gram-positive rod which can be isolated from soil, vegetation, and many animal reservoirs. Human disease due to Listeria monocytogenes is uncommon but occurs most frequently in the neonatal period, during pregnancy and in elderly or immuno-suppressed patients. Listeriosis in pregnant women may cause spontaneous abortion, fetal distress, preterm labor, fetal death, or neonatal septicemia/meningitis. Maternal infection alone may occur without infection of the infant, especially at the end of pregnancy. One case of septicemia with Listeria monocytogenes in pregnant women at the 35th weeks of pregnancy with fetal distress is presented.

A 41-year-old female was admitted to our hospital for self-audible wheezing sound and dyspnea. On past history, she has been suffered from chest discomfort, and treated recurrently by other hospitals. But, there was no symptomatic improvement. A stridor and mixed wheezing sound was auscultated on whole lung field. PFT revealed fixed type or variable intra- & extra-thoracic air way obstructive pattern. By bronchoscopy & bronchogram, we found web-like structure on the distal trachea. A bronchoplasty was performed and the post-operative PFT showed slight improvement & she had no more complaints.

PURPOSE: The aim of this study was to observe clinical course including remission rate during antithyroid medication for Graves' disease in children and adolescents, and to evaluate factors related to remission. METHODS: This is a retrospective study of 42 patients (8 males), who were diagnosed at pediatric endocrine clinic in Chungbuk National University Hospital from January 1994 to December 2009. They were treated with antithyroid drugs only and were followed for at least 2 years. Their average age at diagnosis was 11.5 +/- 3.4 years, and average follow-up period was 4.5 +/- 2.2 years. RESULTS: At diagnosis, 64.3% of the subjects were in puberty, 87.8% showed goiter which was significantly prevalent in females (P < 0.05), and 38.9% manifested exophthalmos. Thyrotropin receptor antibody was positive in all the patients, whereas anti-microsomal antibody was positive in 88.1% and anti-thyroglobulin antibody in 81.0%. Twenty two (52.4%) patients remitted with 4.3 +/- 2.5 years' medication, and the others were continuously medicated at the last follow-up of 4.8 +/- 1.8 years. By quartile estimate for the remission time, 25 percentile was remitted at 3.7 years, 50 percentile at 7.1 years, and 75 percentile at 9.2 years. Among the factors for the remission, initial thyroid stimulating hormone level was significantly lower in non-remission group compared to remission group (P < 0.05). CONCLUSION: In pediatric Graves' disease treated only antithyroid drugs, the time required for remission is so long that it is necessary to establish fixed medication period and to choose definitive treatment modality as in adult Graves' disease through multicenter clinical study.

A 49-year-old man was admitted to Baptist Hospital on September 1, 1990. For mitral valve replacement due to mitral regurgitation. He has been treated by implantation of artificial pacemaker due to complete heart block for 1 year ago. We have experienced anesthetic management above patient who was scheduled of MVR. The patient with a cardiac pacemaker (VVI type) could give anesthesiologist many associated problems during the operation and anesthesia. During anesthesia an anesthesiologist should be able to manage the problems which might occur because of a cardiac pacemaker by various origins. Authors report this case with evaluation of references.

PURPOSE: The definition of continence after radical prostatectomy has not been established. We examined the continence rate and changes in voiding and storage symptoms after laparoscopic radical prostatectomy(LRP). MATERIALS AND METHODS: Fifty-seven patients were enrolled and followed for more than 12 months after a LRP. Postoperative evaluation of urinary incontinence was performed by interview, and was classified as completely dry, intermittent(occasional dribbling only), using only 1 pad/day, using more than 1 pad/day, and no control. Pre- and post-operative International Prostate Symptom Scores(IPSS) were compared(Total, each criterion, and quality of life, voiding, and storage symptom subscores). RESULTS: Sixty seven percent of patients were completely dry and 17% of patients were classified as intermittent. Those using 1 pad/day, more than 1 pad/day, or no control accounted for 2%, 9%, and 5%, respectively. Pre- and post-operative total IPSS and quality of life scores were not different, but urgency and nocturia scores increased(p<0.05). The voiding subscore decreased and the storage subscore increased after LRP(p<0.05), suggesting aggravation of storage symptoms after LRP. CONCLUSIONS: We need to determine which definition of continence is most clinically useful. It is important to assess lower urinary tract symptoms, especially storage symptoms, as well as urinary incontinence after LRP.

Pre-surgical and post-surgical change in adult clef lip and palate patient following Le Fort I advancement osteotomy combined with bone graft was evaluated clinically and cephalometically. We obtained a successful function and esthetic improvement. The bone graft of alveolo-palatal clefts provides a stable bone support to the adjacent teeth of the cleft area, and well union of adjacent bone tissue, the closure of oronasal fistula and improvement of speech problem. Le Fort I osteotomy following the ostectomy of nasal septum for advancement of the maxilla was obtained relative improvement of esthetics and functional occlusion. 1. The orthodontic correction was required before and after surgery. 2. In this case, there was a limited range of anterior advancement of the Premaxillary-segment due to the scar tissue. 3. After 8 months of operation, we could show the new bone deposition on the cleft sites in dental radiograph and then the prosthetic treatment to the missing teeth was done.

We report 13 chromophobe renal cell carcinomas (10.8%) observed among 120 renal cell carcinomas in adults. The average age was 53 (range: 34-72) years old, and 6 were males and 7 females. The mean tumor size was 10 (range: 5-17) cm, mean nuclear grade 2.4, and mean Robson's stage was 1.9. There were two distinct histologic variants; typical variant (n=9) and eosinophilic variant (n=4). Both of them showed typical light microscopic features and positive reaction with Hale's colloidal iron and carbonic anhydrase II, a marker protein of intercalated cells of renal collecting ducts. A strong positive immunoreactivity for epithelial membrane antigen was noted in the cytoplasm in 12 of 13 tumors. Numerous microvesicles, 180~440 nm in diameter, were identified ultrastructurally. DNA aneuploidy was found in 3 out of 10 cases. Neither local recurrence nor metastasis have been identified during the following period of 4~144 (mean 48) months.
