New Cervicography and HPV-DNA test, a adjunctive Pap Smear test, are an innovative cervical cancer surveillance system. The purpose of this study was to investigate the role of HPV-DNA test and cervicography as a pap smear in early detection of cervical cancer. Pap smear, cervicography, and HPV-DNA test data were obtained from 161 patients who visited the Department of Obstetrics and Gynecology, Chunan Hospital, Soonchunhyang University from November 1997 to April 1998. Histologic specimens were obtained from patients in whom abnormalities were detected by either pap smear or cervicogram, and by naked eye. Specimens were taken either by colposcopically directed biopsy or large loop excision of the transformation zone. Results were as follows: 1. Pap smear results were normal in 40 cases (24.8%), RCC (reactive cellular change) or ASCUS (atypical squamous cells of undetermined significance) in 74 cases (46%), and abnormal (above low grade squamous intraepithelial lesion) in 47 cases (29.2%). 2. New Cervicographic findings were negative in 93 cases (57.8%), benign or suspicious atypical in 14 cases (8.7%), and positive in 54 cases (33.5%). 3. The sensitivity (94.6% vs 67.7%, p<0.01), and the false positive rate (19.8% vs 14.6%, p<0.01) of cervicography were significantly higher than for pap smear. The specificity (83.0% vs 86.2%, p<0.01), and the false negative rate (5.4% vs 32.3%, p<0.01) of cervicography were significantly lower than for pap smear. 4. When New Cervicography and Pap smear were used together, the sensitivity was higher than for pap smear in New Cervicography used alone (p<0.01) and the specificity was lower than for pap smear or cervicography used alone (p<0.01). 5. When cervicography and pap smear and HPV-DNA test were used concurrently, the sensitivity was higher than for cervicography and pap smear used together (p<0.01), and the specificity was lower than for cervicography and pap smear used together (p<0.01). The three screening test combination is a useful interval screening method to detect cervical cancer. The detection rate of cervical cancer will be increased. Thus, we believe that cervicography and HPV testing can be important adjuntive tests for cervical cytology, final tool in precancerous cervical lesions prevention. Combination of these three tests is sensitive enough to institute "interval screening" into society.

Recent study showed that peripheral inflammation induced an increased expression of brain-derived neurotrophic factor (BDNF) mRNA which was mediated by nerve growth factor in the dorsal root ganglion (DRG). Therefore, it is conceivable that peripheral inflammation may induce an increase in BDNF synthesis in DRG and consequently enhance the level of BDNF in the spinal cord and that gene expression of trkB mRNA may be altered. In the present study, we evaluated changes in BDNF-immunoreactivity and trkB mRNA in the DRG and spinal cord by means of immunohis-tochemistry and RT-PCR, respectively, following peripheral tissue inflammation produced by intraplantar injection of Freund's adjuvant into rat paws. In addition, coexistence of BDNF and preprotachykinin (PTT) mRNAs, BDNF and CGRP mRNAs or BDNF and trkB mRNAs in the DRG following inflammation was observed by means of in situ hybridization. The results obtained were as follows; 1. Inflammation induced a significant increase of the number of BDNF-immunoreactive (IR) neurons in the ipsilateral DRGs. The increase was observed 1 and 3 days after injection of adjuvant, and the levels had returned to normal by 7 days. In the spinal cord, inflammation also induced an elevation in the expression of BDNF-IR terminals in the medial superficial layers of the ipsilateral dorsal horn and in lamina V 1 and 3 days after injection. 2. There was significant increase of truncated trkB (t-trkB) mRNA in the ipsilateral DRG 3 days following inflammation. Changes in the expression of trkB mRNA in the DRG or trkB and t-trkB mRNAs in the spinal cord were not observed. 3. Many neurons showed increased coexistence of BDNF and PTT mRNAs or BDNF and CGRP mRNAs in the DRG following inflammation. 4. Few neurons showed coexistence of BDNF and trkB mRNAs in the DRG following inflammation. The results suggest a paracrine function for BDNF within the DRG in addition to an important role related with nociception following peripheral inflammation.

BACKGROUND: Bile examination is believed to be the most precise method for detecting Clonorchis sinensis (CS) eggs. We carried out bile examination to evaluate infestation state of CS in patients with pancreatobiliary diseases in Ulsan, known as an endemic area of CS infestation. METHODS: We examined CS eggs in bile in three hundreds and nine patients with pancreatobiliary diseases. The bile was obtained from endoscopic nasobiliary or percutaneous transhepatic biliary drainage tubes. RESULTS: The overall egg positive rate was 27.5% (35.3% in male, 17.6% in female). The egg positive rate was not significantly different according to the age group: 20.0% in thirties, 26.7% in forties, 24.2% in fifties, 29.9% in sixties, 36.2% in seventies and 16.7% in eighties or more. The egg positive rate according to the disease, except CS cholangitis, was not also statistically different: 32.6% in bile duct cancer, 38.5% in gallbladder cancer, 11.1% in ampulla of Vater cancer, 24.0% in pancreatic cancer, 26.4% in gallstone diseases and 12.5% in the reminder. The location of gallstone and whether CS related diseases or CS unrelated diseases did not affect the egg positive rates. The egg positive rate in patients with normal radiological findings including cholangiography was 17.0%. CONCLUSION: This result shows that regardless of age, sex, and sorts of diseases, the infestation rate of CS was very high. On the basis of our results, it is therefore presumes that clonorchiasis is still endemic disease in Korea.

PURPOSE: Hepatolithiasis has been regarded as having a potential of to invoke cholangiocarcinogenesis. The aim of this study was to examine the expression of survivin in hepatolithiasis and cholangiocarcinoma, and to try to predict whether hepatolithiasis plays a role in the carcinogenesis of cholangiocarcinoma. We also investigated the expression of survivin according to subcellular sites (cytoplasmic and nuclear) in the cholangiocarcinoma specimens and to correlation this with the clinical outcome. METHODS: Thirty-four surgically resected hepatolithiasis specimens and ten stone-containing cholangiocarcinoma specimens were the focus of this study. Immunohistochemical staining was done to check the expression of survivin in the hepatolithiasis and cholangiocarcinoma specimens. We classified the survivin positive group according to the subcellular sites in the cholangiocarcinoma specimens. RESULTS: The expression rate of survivin was 5.9% in the hyperplasia specimens, 47.1% in the dysplasia specimens and 90% in the adenocarcinoma specimens (p < 0.01), respectively. The over expression of nuclear and cytoplasmic survivin was seen in 3 specimens and 6 specimens, respectively, among the survivin positive specimens (9 total specimens) of the cholangiocarcinoma specimens. The median survival time of the nuclear and cytoplasmic expression groups of patients was 1.5 months and 10 months, respectively. CONCLUSION: We conclude that the overexpression of survivin in hepatolithiasis could be associated with cholangiocarcinoma based on the sequentially increased survivin expression. We purpose that the nuclear survivin expression predicts aggressive clinical behavior of cholangiocarcninoma.

Endoscopy has been the method of choice for the initial diagnosis and treatment of gastrointestinal bleeding. However, in the case of difficult localization or endoscopic failure, angiographic or surgical alternative may be recommended. The role of angiography has been emphasized recently to control upper GI bleeding. We experienced a case with deep ulcer displaying exposed vessel along the duodenal bulb, which imposed serious rebleeding risk. Although, active bleeding was controlled by the epinephrine injections in that patient, rebleeding risk was still high. So the patient underwent emergency angiography with embolization of the pancreaticoduodenal artery and gastroduodenal artery using multiple microcoils. Follow-up endoscopic examinations showed a coil protruding into the lumen from the ulcer bed, and the exposed coil at the ulcer base was completely by the regenerated epithelium three months later. Here in, we describe the rare case of a endodcopically exposed coil after embolization for bleeding duodenal ulcer which is the first case ever reported in Korea.

Background/Aims:
Bleeding events after percutaneous coronary intervention (PCI) have important prognostic implications. Data on the influence of an abnormal ankle-brachial index (ABI) on both ischemic and bleeding events in patients undergoing PCI are limited.
Methods:
We included patients who underwent PCI with available ABI data (abnormal ABI, ≤ 0.9 or > 1.4). The primary endpoint was the composite of all-cause death, myocardial infarction (MI), stroke, and major bleeding.
Results:
Among 4,747 patients, an abnormal ABI was observed in 610 patients (12.9%). During follow-up (median, 31 months), the 5-year cumulative incidence of adverse clinical events was higher in the abnormal ABI group than in the normal ABI group: primary endpoint (36.0% vs. 14.5%, log-rank test, p < 0.001); all-cause death (19.4% vs. 5.1%, log-rank test, p < 0.001); MI (6.3% vs. 4.1%, log-rank test, p = 0.013); stroke (6.2% vs. 2.7%, log-rank test, p = 0.001); and major bleeding (8.9% vs. 3.7%, log-rank test, p < 0.001). An abnormal ABI was an independent risk factor for all-cause death (hazard ratio [HR], 3.05; p < 0.001), stroke (HR, 1.79; p = 0.042), and major bleeding (HR, 1.61; p = 0.034).
Conclusions
An abnormal ABI is a risk factor for both ischemic and bleeding events after PCI. Our study findings may be helpful in determining the optimal method for secondary prevention after PCI.
