The purpose of this study is to review epidemiological and clinical characteristics of diverticular disease of the colan in Korea and to discuss the difference of the findings from those in other countries. Reviewing all thebarium enema films taken at the Seoul National University Hospital retrospectively for the last 8 years. that is, from January 1, 1980 to December 31, 1987, we observed the annual and overall incidence of the disease, the number and location of the diverticula, and the presenting symptoms of the cases. The results are summarized as follows: 1) Out of the patients examined, 237 cases had one or more diverticula in the colon, the overall incidence being 1.32%, 2) The annual incidence increased progressively for the last 8 years, from 0.25% in 1980 to 2.53% in 1987. 3) The mean age of the patients at the time of diagnosis was 51 years. The male to female ratio was 2.5. 4) The diverticula were located on the right side in 81.0% of the cases, on the left side in 10.6%, and on both sides in 8.4%. 5) In 82 cases (34.6%) single diverticulum was found, whereas 34 cases (14.3%) had more than 10 diverticula. 6) The most frequent symptoms for taking barium enema were abdominal discomfort and pain (34. 2%) and changes in bowel habits (33.8%}, whereas 45 casea (19.0%) had the examination just for a routine health check. In conclusiion, the diverticular disease of the colon is still uncommon in Korea as compared with in western countries, and the right colon type is far more freqtaent than the left colon type. However in recent years the incidence increases quite rapidly and the left colon type is getting more common.

OBJECTIVE: The aim of this study was to evaluate Topotecan-, Cisplatin- and Taxol-induced apoptosis in five human ovarian cell lines as a measure of chemosensitiviy and relationship between apoptosis and p53 and bcl-2 gene expression. METHODS: In this study, the author is presenting data on apoptosis induced by Topotecan, Cisplatin and Taxol in five ovarian cancer cell lines, and represent different levels of sensitivities to Topotecan, Cisplatin and Taxol. This study also includes the interaction of these chemotherapeutic agents on ovarian cancer cell lines with respect to the apoptosis and cytotoxicity assay as a quantitative measure of the efficiency of killing. Presence of the p53 and bcl-2 gene product were examined by western blotting. RESULTS: The five cell lines represent various sensitivities to Topotecan, Cisplatin, Taxol (LD50 range of Topotecan, 30~1000 ng/ml; Cisplatin, 3~10 microgram/ml, Taxol 5~1000 nm). SKOV-3 represent a resistant cell line which was 2~30 times resistant to Topotecan, 3 times resistant to Cisplatin, and 2~200 times resistant to Taxol when compared to others. Demonstration of apoptosis correlated with the sensitivity of the cell lines to Topotecan, Cisplatin and Taxol for SNU-840 and OVCAR-3. DNA fragmentation of OVCAR-3 was uniformly present when treated with Topotecan, Cisplatin and Taxol, 24 or 48 hours. When sequencing experimetns were performed with correlated with cytotoxicity assays, except in SNU-251 cells where no signigicant difference was observed in different interactions of Topotecan, Cisplatin and Taxol. Pretreatment with Topotecan, Cisplatin at a 24 hour interval resulted in enhanced cytotoxicity. Quantitation of the fragmented DNA correlated with that seen on gel electrophoresis. CONCLUSION: The study indicate that the ability to achieve significant cytotoxicity by Topotecan, Cisplatin and Taxol may be related to the induction of apoptosis rather than necrosis. However, outcome of these treatments depend on cellular and genetic characheristics.

The present study was designed to establish comparatively the inhibitory effects of cilnidipine (CNP), nifedipine (NIF), and omega-conotoxin GVIA (CTX) on the release of CA evoked by cholinergic stimulation and membrane depolarization from the isolated perfused model of the rat adrenal medulla. CNP (3 micrometer), NIF (3 micrometer), and CTX (3 micrometer) perfused into an adrenal vein for 60 min produced greatly inhibition in CA secretory responses evoked by ACh (5.32 x 10(-3) M), DMPP (10(-4) M for 2 min), McN-A-343 (10(-4) M for 2 min), high K+ (5.6 x 10(-2) M), Bay-K-8644 (10(-5) M), and cyclopiazonic acid (10(-5) M), respectively. For the CA release evoked by ACh and Bay-K-8644, the following rank order of potency was obtained: CNP > NIF > CTX. The rank order for the CA release evoked by McN-A-343 and cyclopiazonic acid was CNP > NIF > CTX. Also, the rank orders for high K+ and for DMPP were NIF > CTX > CNP and NIF > CNP > CTX, respectively. Taken together, these results demonstrate that all voltage-dependent Ca2+ channels (VDCCs) blockers of cilnidipine, nifedipine, and omega-conotoxin GVIA inhibit greatly the CA release evoked by stimulation of cholinergic (both nicotinic and muscarinic) receptors and the membrane depolarization without affecting the basal release from the isolated perfused rat adrenal gland. It seems likely that the inhibitory effects of cilnidipine, nifedipine, and omega-conotoxin GVIA are mediated by the blockade of both L- and N-type, L-type only, and N-type only VDCCs located on the rat adrenomedullary chromaffin cells, respectively, which are relevant to Ca2+ mobilization. It is also suggested that N-type VDCCs play an important role in the rat adrenomedullary CA secretion, in addition to L-type VDCCs.

OBJECTIVE: To compare the safety and efficacy of intravaginal misoprostol versus oral dinoprostone for labor induction at term. METHODS: One hundred of patients at term were randomized to receive either 50microgram of misoprostol vaginally every 4 hours or dinoprostone 0.5mg orally every 1 hour for the maximum of six doses. Intravenous infusion of oxytocin was administered under such circumferences as the patient did not go into active labor after maximum dose, SROM was developed without an adequate contraction pattern, or the patient had arrest of dilatation(no change in cervical dilatation for 2 hours). We compared the frequency of oxytocin augmentation, administration to delivery interval, vaginal delivery rate within 12 hours and 24 hours, intrapartum complications, induction failure, mode of delivery, neonatal outcomes, and maternal complications between two groups. RESULTS: The average interval from administration to delivery was shorter in the misoprostol group(739.4+/-372.4min vs 1087.7+/-765.1min, p<0.05), but the interval from administration to vaginal delivery of each group was similar(724.3+/-375.4min vs 800.3+/-697.0min). Regarding the frequency of vaginal delivery within 24 hours, however, misoprostol group was higher than dinoprostone group(88% vs 56%, p<0.001). And oxytocin augmentation of labor occurred less commonly in misoprostol group than in dinoprostone group(20% vs 76%, p<0.05). Any statistically significant difference in intrapartum complications, mode of delivery, and neonatal or maternal adverse outcome was not appeared between these two group. CONCLUSION: Vaginal misoprostol is as effective and safe as oral dinoprostone for cervical ripening and induction of labor at term. In addition, vaginal misoprostol contributes the curtailment of labor induction expenditure due to its moderate price; misoprostol costs 100 won per 50microgram.

BACKGROUND/AIMS: Viral breakthrough has been considered a major limitation of lamivudine in the treatment of hepatitis B virus related chronic liver disease. Its clinical meaning has not been thoroughly assessed. METHODS: 64 patients who showed viral breakthrough during lamivudine treatment were retrospectively reviewed. We evaluated the rate of HBeAg seroconversion and hepatic decompensation after viral breakthrough. RESULTS: After viral breakthrough, serum alanine transaminase (ALT) elevation more than 1.2X upper limit of normal (ULN) was noticed in 40 patients (62.5%). Acute flare (serum ALT elevation >X5 ULN, or serum bilirubin >3 mg/dL) occured in 15 patients (23.4%). During the period of follow up (15.0 +/- 9.7 months; range, 0-31 months) since viral breakthrough, decreased serum HBV-DNA level to below the detection limit and serum ALT normalization was seen in 15 patients (23.4%). HBeAg seroconversion was noticed in 7 (13.7%) of a total of 51 HBeAg positive patients at base line; in 4 (15.4%) of 26 patients with non-hepatic failure (chronic hepatitis or Child-Pugh class A liver cirrhosis) at base line; and in 2 (40.0%) of 5 patients with non-hepatic failure at base line and acute flare after viral breakthrough. During this period, terminal hepatic decompensation (Child-Pugh class C) or death was noticed in 9 (90.0%) of 10 patients who had hepatic decompensation (Child-Pugh class B or C) at baseline and acute flare after viral breakthrough. CONCLUSIONS: Acute flare after viral breakthrough seemed to continue during HBeAg seroconversion and rarely developed into terminal hepatic decompensation or death in patients with non-hepatic decompensation at baseline. Its incidence is not only high but lethal to most patients with hepatic decompensation at baseline.

Acute vertebrobasilar artery occlusion is a fatal event, even after intra-arterial thrombectomy and thrombolysis. We are reporting a case of acute vertebral artery (VA) occlusion. A 37-year-old man was admitted with mild dizziness, but cardiopulmonary arrest suddenly developed after eleven hours. We performed cardiopulmonary resuscitation immediately and his mental and vital state was recovered. Thus we performed intra-arterial thrombectomy, thrombolysis and balloon angioplasty for left vertebral artery occlusion. But pre-existing stenosis of VA was revealed during intervention so we inserted a stent to the stenotic area. Conclusively, we obtained the good angiographical and clinical outcomes.

The aim of this study was to evaluate the clinical effect of a continuous infusion of urokinase in cerebral stoke patients who were late admitted over 6 hours after onset. From January to December in 2008, acute cerebral stroke patients (n=143) treated with intravenous urokinase infusion (Group I, n=93) or not (Group II, n=50) after 6 hours and within 72 hours of stroke onset were reviewed. Continuous intravenous infusion of urokinase was done for 5 days. The clinical outcome for each patient was evaluated by using the modified National Institutes of Health Stroke Scale (NIHSS) on admission and on the day of discharge. The NIHSS score was decreased at discharge compared with admission in the urokinase treatment group (Group I; from 4.8+/-2.2 to 3.8+/-1.9; p=0.002). There was an improvement in the patients who initiated urokinase treatment within 24 hours from stroke onset in Group I (from 5.1+/-1.9 to 3.9+/-1.5; p=0.04). In patients with initiated urokinase treatment within 24 hours from stroke onset, intravenous urokinase infusion could be an effective modality in acute ischemic stroke patients admitted later than 6 hours after onset.

Background/Objectives:
To analyze the clinical characteristics of differentiated thyroid cancer (DTC) in children and adolescents.Materials & Methods: Medical records of 31 DTC cases that were diagnosed and treated at Korea Cancer Center Hospital between 2002 and 2018 were retrospectively reviewed.
Results:
Most cases were papillary carcinoma (n=26), with female predominance (n=25). Median age was 16.4 years (range, 11.9-18.6 years). Extrathyroidal extension was present in 24 cases. Twenty cases had tumor involvement at cervical lymph nodes and three had lung metastasis. Twenty-two patients received radioactive iodide treatment with a median cumulative dose of 300 mCi (range, 100-920 mCi). During a median follow-up of 68.2 months (range, 2.3-191.4 months), serum thyroglobulin level was elevated in 15 patients. Among them, two cases had remnant thyroid tissue, 4 had recurrence at cervical lymph nodes, and the remaining 9 did not have any detectable lesion. All were alive, and 5-year event-free survival (EFS) was 45.2±10.1%. Age £15 years, tumor size, lymph node status (N1b), and distant metastasis had negative effects on EFS. On multivariate analysis, age and tumor size had prognostic significance.
Conclusion
For DTC of children and adolescents (£18 years old), age ≤15 years and tumor size were prognostic factor. Therefore, patients in this age group need meticulous follow-up. Further studies are necessary to answer the potential influence of age on the incidence and behavior of DTC.
