A spontaneous rupture into the sigmoid colon and peritoneal cavity is a most unusual complication for a mature cystic teratoma of the ovary. A 38-year-old woman with acute lower abdominal pain, presenting as peritonitis, visited our hospital. Physical examination revealed tenderness, rebound tenderness, and vague palpable mass in the right lower quadrant of the abdomen. A pelvic computed tomographic scan demonstrated a right ovarian cystic mass with bone and fat tissue, which had ruptured into the sigmiod colon, and peritoneal fluid collection. During a laparotomy, the ovary tumor was found to be densely adherent to the rectosigmoid junctional wall; also a solid element of the ovary tumor containg hair and skin tissue seemed to be in continuity with colonic lumen, and the ovarian wall was ruptured with spillage of purulent exudate into the peritoneal cavity. En bloc resection of the tumor-bearing segment of the sigmoid colon, together with the adherent right ovary and salpinx was carrried out. The diagnosis of a mature teratoma of the ovary was made by histologic examination of a surgical specimen; the tumor had perforated the sigmoid colon wall, had protruded into the bowel lumen, and had ruptured the intraperitoneal cavity due to inflammation its wall.

PURPOSE: Gastric emptying after a gastric resection has been studied in early gastric cancer. Most reports are retrospective and show that gastric emptying after gastroduodenal reconstruction is faster than normal. This study was designed to evaluate the gastric-emptying pattern after a gastroduodenal reconstruction with preservation of the truncal vagus nerve had been performed on a patient whose preoperative gastric-emptying time had been normal. METHODS: From July 1996 to February 1998, we performed a distal gastrectomy with gastroduodenal reconstruction with preservation of the truncal vagus nerve in 11 patients (9 patients with early gastric cancer, 1 patient with advanced gastric cancer, and 1 patient with high-grade dysplasia) whose preoperative gastric-emptying times was normal. To evaluate the gastric emptying after the gastrectomy and gastroduodenal reconstruction, we analyzed the lag time (when 10% of food is delivered to the duodenum), T1/2 (when 50% of food is delivered to the duodenum), and the residual food in the stomach after 100 minutes (%) by means of radionuclide scintigraphy using a single-head gamma camera after ingestion of an 99mTc-tin-colloid steamed egg. We defined the delayed gastric emptying as T1/2 longer than the mean of the preoperative value by 2 standard deviation. RESULTS: Among the 11 patients with gastroduodenal reconstruction, gastric emptying was normal in 4 patients and delayed in 7 patients; only one of the delayed cases has GI symptoms such as early satiety. There were no rapid gastric emptying cases. CONCLUSION: Rapid gastric emptying after gastroduodenal recon struction with preservation of the truncal vagus nerve was rare.

PURPOSE: Invariant natural killer T (iNKT) cells play a critical role in the pathogenesis of asthma. We previously reported the association between circulating Th2-like iNKT cells and lung function in asthma patients and the suppressive effect of Toll-like receptor 5 ligand flagellin B (FlaB) on asthmatic in a mouse model. Thus, we investigated whether FlaB modulates the function of circulating iNKT cells in asthmatic patients. METHODS: Peripheral blood mononuclear cells (PBMCs) were treated with FlaB, and the secreted and intracellular cytokines of iNKT cells were evaluated by using ELISA and flow cytometry, respectively, following stimulation with alpha-galactosylceramide. Foxp3+ iNKT cells were also measured. To determine the effect of FlaB-treated dendritic cells (DCs) on iNKT cells, we co-cultured CD14+ monocyte-derived DCs and T cells from patients with house dust mite-sensitive asthma and analyzed intracellular cytokines in iNKT cells. RESULTS: A reduction of IL-4 and IL-17 production by iNKT cells in PBMCs after FlaB treatment was alleviated following blocking of IL-10 signaling. A decrease in the frequencies of IL-4+ and IL-17+ iNKT cells by FlaB-treated DCs was reversed after blocking of IL-10 signaling. Simultaneously, an increase in Foxp3+ iNKT cells induced by FlaB treatment disappeared after blocking of IL-10. CONCLUSIONS: FlaB may inhibit Th2- and Th17-like iNKT cells and induce Foxp3+ iNKT cells by DCs via an IL-10-dependent mechanism in asthmatic patients. In patients with a specific asthma phenotype associated with iNKT cells, FlaB may be an effective immunomodulator for iNKT cell-targeted immunotherapy.

PURPOSE: Intussusception is one of the most common causes of intestinal obstruction in children under the age of 2 years, especially in male. In this study, we compared the results of pressure reductions for various treatment methods and identified the factors related to reduction failure. METHODS: From Jan. 1996 to Dec. 1997, 87 barium reductions and 127 air reductions were performed for childhood in tussusception. Success rates of these non-operative managements and factors affecting those rates were analyzed. RESULTS: 1) When only ileocolic intussusceptions were considered in order to exclude the effect of different type of intussusceptions, the success rate for air reduction (AR) was 83.5%, which was significantly higher than 71.8% in barium reduction (BR). 2) Factors affecting reduction failure were history of preceding upper respiratory infection, fever (> or =38oC) and symptom duration in BR, and abdominal distension, leukocytosis (> or =10,000/mm3), and symptom duration in AR. 3) Bowel perforations were occurred in 3 cases of AR, but all of these cases showed bowel wall infarction requiring bowel resection, and complications due to perforations were minimal. There were no BR-related complications in BR. 4) Intussuception recurred in 7.4% of all cases; 4.9% after BR, 9.3% after AR. The mean intervals between previous reduction and recurrence were 37.0 (range 1-88) days in BR and 64.3 (range 2-283) days in AR. Recurrences occurred within 48 hours after reduction in 2 cases of BR and in 3 cases of AR. CONCLUSION: Compared with conventional barium reduction, air reduction had a relatively higher success rate in managing childhood intussusception, in spite of a slightly higher risk of bowel perforation. However, perforation did not significantly affect the clinical course. Therefore, air reduction is one of the good alternative of conventional barium reduction for managing childhood intussusception.

PURPOSE: This study evaluated the usefulness of a new scoring system in diagnosing acute appendicitis which expresses the patient's symptoms, physical examination, and laboratory findings more clearly and objectively. METHODS: A prospective study was conducted with 314 patients who were hospitalized with suspicion of acute appendicitis. After analyzing the symptoms, physical examination, and laboratory findings, 10 meaningful variables were selected, each of which were scored separately. The diagnostic value of the new scoring system was evaluated, and analyzed in comparison to the preexisting Alvarado score. RESULTS: Ten variables including vomiting, migration pain, fever, Dunphy's sign, Rovsing's sign, tenderness, rebound tenderness, increased white blood cell counts, increased neutrophil proportion, and increased CRP levels were associated with acute appendicitis. The new scoring system is developed by applying 1 point for each variable, with a total score of 10 points. In the new scoring system, a score above 5 points had sensitivity of 0.75, specificity of 0.73, positive predictive value of 0.92, and diagnostic accuracy of 0.71. The area under the receiver operating characteristic curve was 0.80, which is larger than 0.72 of the preexisting Alvarado score, and thus has a higher diagnostic accuracy. As acute appendicitis progresses, the average score tends to become significantly higher (P=0.001). CONCLUSION: The new scoring system, which objectively reflects the clinical variables of the patient's symptoms, physical examination and laboratory findings, will be useful in accurately diagnosing acute appendicitis and in quickly deciding a therapeutic policy in patients with right lower abdominal pain.

Alverine citrate is one of the most commonly used antispasmodic drugs for patients with irritable bowel syndrome. Alverine-citrate-induced hepatotoxicity is extremely rare, with only a few cases having been reported worldwide. We present a case of a 75-year-old female patient who experienced complicated jaundice and abdominal discomfort after taking alverine citrate. Other causes of hepatitis were ruled out and the results of the liver function test returned to normal after ceasing the drug. This is the first case report in Korea of alverine-citrate-induced hepatotoxicity.

Despite the major advances in diagnostic technology and improvements in antimicrobial selection and monitoring accompanied by parallel advances in surgical techniques, the morbidity and mortality of infective endocarditis(IE) still remain high. Because of this high mortality rate, it is worthy of investigating the clinical features of IE and it's complications thoroughly. The main causes of mortality in IE are congestive heart failure and septic embolization. In 9% of active IE, acute myocardial infarction(AMI) developed. AMI caused by coronary artery obliteration by occlusion or embolization is a rare but recognized complication of aortic valve endocarditis with annular abscess. We reported a case of aortic valve endocarditis with aortic root abscess which was complicated by AMI and death.

Gastric metastasis of malignant tumors is relatively rare but has been reported in cases of malignant melanoma, lung cancer, breast cancer and squamous cell carcinoma of the esophagus. Primary small cell carcinoma of the esophagus is very rare and is an extremely aggressive tumor. Regional lymph node involvement, and distant metastasis to other organs including liver, bone, skin, lung, bone marrow, and brain are common at the time of initial diagnosis. To date, there has been no case reported of gastric metastasis from primary esophageal small cell carcinoma. A 72-year-old man presented with dysphagia for 2 months. An esophagogastroduodenoscopy revealed esophageal carcinoma with a submucosal tumor in the upper body of the stomach. Pathologic examination revealed an esophageal small cell carcinoma, and gastric submucosal infiltration of the small cell carcinoma was noted. We report a case of primary esophageal small cell carcinoma with submucosal tumor like gastric metastasis.

The coronary artery-left ventricular microfistula is an extremely rare congenital anomaly. Little is known about their epidemiologic and clinical features. Moreover, to our knowledge, only two cases of coronary artery-left ventricular microfistulae demonstrated by transthoracic doppler echocardiography have been reported in the literature. Recently we experienced a case of coronary artery-left ventricular microfistulae demonstrated by transthoracic doppler echocardiography, who was a 63 year old woman and visited for evaluation of chest pain. Herein, along with a review of the pertinent literature regarding this disorder, we report a case of coronary artery-left ventricular microfistulae demonstrated by transthoracic doppler echocardiography.

Infective endocarditis is a life-threatening condition caused by microbial infection of the heart's endocardial surface. This condition can also be associated with bacterial infections of other organs. We experienced an unusual case of recurrent infective endocarditis associated with pyogenic spondylodiskitis. A 70-year-old man presented with persistent fever and lower back pain visited our hospital. The patient had a past history of recurrent infective endocarditis. He was diagnosed with infective endocarditis again based on clinical symptoms and echocardiographic findings. Magnetic resonance imaging was used to evaluate lower back pain, which showed acute spondylodiskitis on L3 and L4 vertebrae. The patient completely recovered following four weeks of antibiotic therapy.
