As gastroduodenoscopy performed more frequently, case reports of human echinostomiasis are increasing in Korea. A Korean woman presented at a local clinic with complaints of abdominal pain and discomfort that had persisted for 2 weeks. Under gastroduodenoscopy, two motile flukes were found attached on the duodenal bulb, and retrieved with endoscopic forceps. She had history of eating raw frog meat. The two flukes were identified as Echinostoma hortense by egg morphology, 27 collar spines with 4 end-group spines, and surface ultrastructural characters. This report may prove frogs to be a source of human echinostome infections.

Congenital origin intestinal obstruction are important disease due to required emergency operation. So accurate and rapid diagnosis needed for decreased mortality and morbidity. Radiologic must defect to accurate obstruction site and also associated other congenital anomalies. And also embryological basis are very important role to the diagnosis of these diseases. We were analyzed radiologically and clinically 25 cases with congenital origin intestinal obstruction with review of literature. 1. Hypertrophic pyloric stenosis 6 cases, midgut malrotation 4 cases, congenital megacolon 8 cases, imperforated anus 5 cases, ileal atresia 1 case and duodenal atresia 1 case. 2. Male and female radio was 16:9. Especially on hypertrophic pyloric stenosis, 5 cases were male infants. 3. All cases of hypertrophic pyloric stenosis represented string sign and also pyloric beak sign, shoulder sign on UGI. 4. 1 case duodenal atresia showed double bubble sign on simple abdomen x-ray and ileal atresia showed mechanical small bowel obstruction sign with microcolon. 5. On midgut malrotaton, cecum was located in right upper abdomen on 4 cases. And 2 cases were associated with Ladd's band, 1 case with volvulus and 1 case with mesenteric defect. 6. Involved site of all congenital megacolon were localized to rectosigmoid colon. 7. On 5 cases imperforated anus, 3 cases were low type and 2 case high type. Rectoperitoneal and rectourogenital fistula were demonstrated on 4 cases.

The abdominal tumors in children are different from those of adult. These tumors are the third most common one, preceded by leukemia and brain tumors, in children under 15 years. X-ray examination is the most important method among diagnostic approaches. The role of diagnostic imaging is to identify the precise anatomic location and extent of pathologic process with the minimal number of imaging procedures. 23 cases of abdominal tumors were reviewed in respect of age incidence, site of origin, radiologic findings. The results are briefly summarized as follows: 1. Neuroblastoma was the most common (6 cases) and wilm's tumor (5 cases), choledocal cyst (4 cases), ovarian mass (3 cases), hydronephrosis (2 cases), were descending order in frequency. 2. The most common site was retroperitoneum (60%) Kidney was the single most common site of origin. 3. Radiologic findings. The most common findings of plain radiography was ill defined soft tissue mass and this method was helpful in the presence of calcification especially in neuroblastoma. Ultrasonographic pattern was anechoic (cystic), echoic or mixed pattern, but this method provide less precise anatomical details, nevertheless Ultrasonography was particularly useful imaging modality for the pediatric abdominal tumors. IVP findings were renal displacement, caliceopelvic system distortion or nonvisualization of kidney, these information was helpful in determining the location of tumors. CT scan showed homogenous or inhomogeneous, cystic or solid, mass with their anatomic location. 4. Ultrasonography was the most widely used specific diagnostic method, but had limited value in detecting the anatomic location of tumors. CT scan was superior to ultrasound for determining the extent of tumors.

Swallowing is a rare cause of syncope. In swallowing syncope, loss of consciousness occurs during or immediately after a swallow. It is mediated via an esophagocardiac vagal reflex arc. The efferent impulse originates in the esophageal sensory endings of the vagus nerve and from the dorsal vagal nucleus an efferent vagus nerve to the heart cause bradycardia or varying degrees of heart block. Bradycardia or heart block in response to swallowing produces decreased cardiac output and results in cerebral hypoperfusion and loss of consciousness. It is occasionally associated with the esophageal or heart disease. The esophageal or heart disease may exaggerate the reflex. We report a patient who had loss of consciousness during swallowig and had a esoophageal submucosal tumor. In EKG monitoring a swallowing induced sinoatrial black was found.

We studied to evaluate CT characteristics of bronchogenic cysts. We retrospectively evaluated CT of 11 patients with pathologically proved bronchogenic cyst. Precontrast and postcontrast CT scan was performed in all. We analyzed CT with viewpoints of location, size, attenuation on pre- and postcontrast scan, and calcification. Three of 11 bronchogenic cysts were intrapulmonary in location and eight were located in the mediastinum. Two of 3 intrapulmonary bronchogenic cysts were located in the right lower lobe, and the remaining one was left lower lobe. Intrapulmonary bronchogenic cysts ranged from 6cm to 12cm in diameter (average, 9.7 cm). On Cr, intrapulmonary bronchogenic cysts appeared as thin-wall air cyst, homogenous water attenuation and soft tissue attenuation with air bubble respectively. Mediastinal bronchogenic cysts were located in posterior mediastinum(n=5), superior mediastinum(n=2), middle mediastinum(n=1) respectively. These cysts ranged in size from 3cm to 8cm in diameter (average, 5.0 cm). On CT, five showed homogenous water attenuation, two soft tissue attenuation similar to that of muscle, one air-fluid level. Calcification or contrast enhancement was not detected in any cases. On operative findings, all of intrapulmonary bronchogenic cysts contained dirty pus-like material and all of mediastinal bronchogenic cysts contained whitish or yellowish mucus material. Bronchogenic cysts showed homogenous water density in many cases, homogenous soft tissue density, air-fluid level and air-filled cyst. The constellation of CT findings may be helpful in the diagnosis and

PURPOSE: p53 mutations are one of the most common genetic alterations in human lung cancer. Although the prognostic value of mutant p53 is still debated, it is widely accepted as a relatively early genetic event in the development and progression of lung cancer. Moreover, there are growing reports about an association between smoking and p53 mutation, suggesting that the p53 gene could be a target of the smoking associated carcino- genesis in the lung cancer. MATERIALS AND METHODS: Surgically resected 89 primary non-small cell lung cancers were obtained from May of 1995 to May of 1997. p53 expression and Ki-67 expression were measured by immunohistochemistry, and each p53 expression and smoking amount were compared with Ki-67 expression and other clinical prognostic factors. RESULTS: Positive p53 expressions were found in 52 (58%) specimens, including 38 (69%) squamous cell carcinomas, 11 (39%) adenocarcinomas, and 3 (50%) large cell carcinomas, and closely associated with male and squamous cell carcinoma. Also close correlation was observed between smoking amount and p53 expression by the regression analysis. But p53 and Ki-67 expression showed no associations in pathologic stage and survival, and there was no association between p53 expression and survival after adjuvant radiotherapy. CONCLUSION: Smoking seems to affect p53 mutations in non-small cell lung cancer, and additional efforts are needed to evaluate the carcinogesis of lung cancer.

PURPOSE: The purpose of this study is to investigate the effects of aging and various risk factors on the oral environment and to analyze them in 3-dimensions. MATERIALS AND METHODS: A total of 800 patients were enrolled in this study, and subjects were divided into 4 groups by age-under 55, 56 – 65, 66 – 75, and over 76. Based on their most recent visit, the number of crowns, bridges, implants, and the remaining natural teeth were recorded. Smoking habits, along with presence of diabetes and hypertension, were surveyed, as risk factors were also set as a variable. Comparisons among the groups or within the groups were performed by independent t-test, and one-way and two-way ANOVA. Kruskal-Wallis test and Mann-Whitney U test were used for analysis. It was assumed to be statistically significant when P value is below .05. RESULTS: Changes in the number of crowns, bridges, implants, and the remaining natural teeth by age were statistically significant. When we examined the effect of risk factors on the change of variables with age, hypertension was found to affect the number of bridges. Diabetes and smoking were found to affect the number of the remaining natural teeth. The other variables were not statistically significant. CONCLUSION: Aging is considered to be an important variable affecting the change of oral environment. Among the risk factors, the presence of smoking habit and diabetes is thought to have a great influence on the change of the number of the remaining natural teeth.

In malignant bone and soft tissue tumors, lung is the most predilection site of metastasis and multiple pulmonary metastases is a poor prognostic factor. Aggressive treatment of pulmonary metastases may offer a chance of long term survival in selected patients whose primary tumors were controlled. We wanted to know the feasibility of pulmonary metastasectomy, whether it can prolong the survival. From Apr. 1989 to Dec. 1993, pulmonary metastasectomies were carried out for 20 patients, and followed up to Sept. 1994, with average follow-up period of 18.7(2-65) months. The primary malignant tumors were 8 in bone and 12 in soft tissues. Mean age was 27.5(12-70) years. Fifteen cases showed late metastasis after control of primary tumor(late metastasis group), and 5 cases showed pulmonary metastasis at first visit(initial stage III group). As a control we analyzed the survival of 24 cases of no treatment after pulmonary metastasis from bone or soft tissue sarcoma, during the same period of investigation. At final follow-up, in late metastasis group, 4 cases were in no evidence of disease (NED), 4 alive with disease (AWD) and 7 dead of disease (DOD). Tumor free interval (TFI) of NED and AWD was averaged 30 months, and for DOD 9.8 months. Five among 11 cases (45%) of multiple lung metastases and 3 among 4 cases (75%) of single metastasis were alive. In initial stage III group, 1 case was in NED, 1 AWD and 3 DOD. For late metastasis group, Kaplan-Meier's 5-year estimated survival rate from the first metastasectomy was 37.4%. The median survival period of 15 cases was 44 months. For initial stage III group, Kaplan-Meier's 9 months estimated survival rate was 40%. Median survival period was 8 months. Twenty four cases of no treatment cases died within 14 months from diagnosis of pulmonary metastasis. Their median survival period was 6 months. Pulmonary metastasectomy appears to prolong survival and occupies an important mode of treatment for late pulmonary metastases in malignant bone and soft tissue tumor patients. In the cases of initial stage III, more cases and follow up period are needed to have a conclusion.
