This report describes a case of portal hypertension caused by periportal tuberculous lymphadenitis. There were a few reports of portal hypertension associated with tuberculosis. A 27-year-old man was admitted to the hospital because of recurrent hematemesis for 7 days. There was a history of mediastinal tuberculous lymphadenitis 3 years earlier that was treated with isoniazide, rifampin, ethambutol, and pyrazinamide for 2 years. Clinical evaluation revealed esophageal variceal bleeding and main portal vein obstruction by enlarged periportal lymph nodes. The patient underwent distal splenorenal shunt. Pathologic examination of the excised periportal lymph node revealed chronic granulomatous inflammation with central caseous necrosis. Thereafter the patient took antituberculous medication for 12 months. The patient has not re-bled 3 years since the shunt operation.

BACKGROUND AND OBJECTIVES: Electrical dyssynchronicity (Dsyn) appears to be prognostic of survival in congestive heart failure (CHF). Recent study has shown some discrepancy between the electrical Dsyn and the Doppler tissue image (DTI) assessed mechanical Dsyn. The aim of our study was to evaluate the relationship between the QRS duration and DTI assessed Dsyn. SUBJCETS AND METHODS: One hundred and forty patients, with CHF and left ventricular ejection fractions < or =40%, were enrolled. DTI was performed on 5-basal and 5-mid segments to assess the time from the R-wave to the peak systolic velocity (RS time). A QRS duration >130 msec, standard deviation (SD) of the RS time >40 msec, or a difference in the maximal and minimal RS times (RS time-diff) >100 msec were indicators of'Dsyn'. RESULTS: The prevalence of myocardial Dsyn, by QRS duration, SD of the RS time and the RS time-diff were 19, 43 and 47%, respectively. The SD of the RS time (49.8+/-23.6 vs. 36.6+/-20.7, p<0.01) and the RS time-diff (139.2+/-63.2 vs. 98.0+/-54.3, p<0.01) were prolonged in the wide (>130 msec) compared with the narrow QRS group. There was also a weak positive correlation between the QRS duration and the SD of the RS time (R=0.34, p<0.001) and the RS time-diff (R=0.38, p<0.001). However, from a cross-tabulation analysis, more than one third of patients had a discrepancy between QRS duration and DTI assessed mechanical Dsyn. From a multivariate analysis, a major determinant of the SD of the RS time was the QRS duration. CONCLUSION: Although a major determinant of the DTI assessed Dsyn was the QRS duration, more than one-third of patients had a discrepancy between electrical and mechanical Dsyn. Therefore, not only the QRS duration, but the DTI assessed Dsyn, should be measured when considering cardiac resynchronization therapy.

BACKGROUND AND OBJECTIVES: Several echocardiographic methods, such as ejection fraction, fractional shortening, and Doppler tissue imaging (DTI), have been developed to quantify systolic function but all had several important limitations. The purpose of this study was to quantify the regional wall motion abnormality, using strain, in an acute myocardial infarction, compared with a visual estimation. SUBJECTS AND MEHTODS: Forty-five patients, with acute anterior (n=28) and inferior myocardial (n=17) infarctions, who underwent color DTI, were examined using longitudinal strain and standard echocardiography, and the results were compared with 54 normal controls. A total of 594 segments [3 segments (apical, mid and basal portion) of septum and inferior wallx99 patients] were evaluated. RESULTS: In the normal control group, the strain was uniformly distributed in all segments (-20%~-23%). In the infarction groups, the strain was negatively related with the wall motion score. The strain of the apical segments and mid-septum was decreased in the anterior wall infarctions, and the strain of basal septum and mid to basal inferior wall was decreased in the inferior wall infarctions. The dyskinetic segments showed positive strain. CONCLUSION: This study validates strain as a superior method for the quantification of the regional wall motion abnormality in an acute myocardial infarction than visual estimation.

BACKGROUND AND OBJECTIVES: Recent studies have implicated inflammation in the pathogenesis of coronary artery disease. The aim of this study was to determine whether C-reactive protein (CRP) levels are predictive of major adverse cardiac events (MACE) following stenting. SUBJECTS AND METHODS: The study comprised 193 patients (90 men, 152 unstable angina, mean age 63 years) between October 1999 and March 2001. The patients were classified into 2 groups according to their MACE, [group A; MACE (+), n=46 and group B; MACE (-), n=147]. RESULTS: During clinical follow-up at a mean duration of 15 months, there was 1death, 7 myocardial infarctions, 25 cases of revascularization therapy, and 13 recurrent anginas. At 24 hours after stenting, the CRP levels were significantly higher in group A compared to group B (5.4, 0.6-15.2 vs. 3.1, 0.1-9.8 mg/L, respectively, p<0.01), with the elevation of the CRP level ( >8.0 mg/L) occurring more commonly in group A than group B (24% vs. 9%, p<0.05). The differences in the CRP levels between the baseline and 24 hours following stenting (CRP 24h-base ) were also significantly higher in group A than in group B. After adjustment for age, sex, and cardiovascular risk factor, multi-variate analysis using logistic regression revealed the CRP levels 24 hours after stenting were predictive of MACE, with an odd ratio of 1.6 (95% CI 1.1-2.2, p=0.01). CONCLUSION: CRP levels, 24 hours following intervention, are powerful predictor of cardiac events in patients with stable or unstable angina undergoing coronary stenting. These results suggest that the inflammatory responsiveness to coronary intervention can plays an important role in predicting cardiac events.

BACKGROUND AND OBJECTIVES: The recovery of the left ventricular ejection fraction (LVEF) appeared to be prognostic of survival in congestive heart failure (CHF). The aim of our study was to evaluate the parameters that appear to predict the LVEF recovery in CHF. SUBJECTS AND METHODS: Forty-nine patients, with CHF and a LVEF< 35%, were enrolled. Doppler myocardial imaging was performed on 5-basal and 5-mid segments in order to assess the systolic duration, the time from the R-wave to the peak systolic velocity (RS time) and the time from the R-wave to the peak early diastolic velocity (RE time). The standard deviation (SD) of the RS time was an indicator of the 'systolic synchronicity'. After at least 3 months of full medical therapy, a follow-up echocardiography was performed. According to the changes in the LVEF, the patients were divided into groups I (< 5%, n=29) and II (> or =5%, n=20). RESULTS: The baseline clinical and echocardiographic parameters were similar in both groups. In group II, the LV end-systolic and end-diastolic volumes were decreased, but the LVEF was increased by up to 44% at the follow-up. The right ventricular annulus velocity (group I: 6.7+/-2.1 vs. group II: 8.0+/-2.0 cm/sec, p< 0.05), the use of beta-blocker (69 vs. 100%, p< 0.05) and the SD of the RS time (46+/-21 vs. 21+/-12, p< 0.01) were significantly different between the two groups. However, the systolic duration and the SD of the RE time were similar in the two groups. From a multivariate analysis, only the SD of the RS time was an independent predictor of the LVEF recovery. CONCLUSION: Myocardial systolic synchronicity is an important predictor of the LVEF recovery.

BACKGROUND: Inflammation plays a key role in the pathogenesis of an in-stent restenosis because it promotes neointimal proliferation. This study was performed to determine responses of the C-reactive protein (CRP) in unstable angina patients with an in-stent restenosis undergoing repeated percutaneous transluminal coronary angioplasty (re-PTCA). METHODS: The study subjects (unstable angina) were classified into 2 groups:Group A (n=30, 15 men, mean age 62 years) had a re-PTCA for an in-stent restenosis lesion and Group B (n=60, 33 men, mean age 63 years) underwent a stent implantation for a de novo lesion. RESULTS: The baseline CRP levels in group A were significantly lower than in group B, as well as 6 and 24 hours after intervention. Twenty four hours after intervention, the CRP levels increased (>4 mg/L) in 3 out of 30 patients (10%) of group A but increased in 32 out of 60 patients (53%) in group B (p<0.001). The differences in the CRP levels between the baseline and 24 hours after intervention were significantly lower in group A than in group B (0.8 and 2.15 mg/L, respectively, p<0.001). In group B, the serum CRP levels 24 hours after intervention were significantly higher than the baseline levels (p<0.05), but not in group A. CONCLUSION: The CRP expression level is significantly lower in unstable angina patients undergoing a re-PTCA for an in-stent restenosis than those undergoing a stent implantation for a de novo lesion.

Anisakiasis is an infection in humans caused by larval nematodes of the family Anisakidae and is encountered in people who eat inadequately prepared raw, salt-water fish or "sashimi". This clinical syndrome is characterized by severe cramping abdominal pain, nausea, and vomiting. Because Koreans like to eat raw fish, anisakiasis of the stomach has been reported occasionally, but the incidences of upper gastrointestinal bleeding caused by anisakiasis has been very rare. The present case is a 30 year-old male Admitted with an episode of hematemesis. A gastrofibroscopy revealed a mucosal laceration and the larva of Anisakis on the esophagogastric junction. We report one case of Mallory-Weiss Syndrome due to gastric Anisakis larva, confirmed by an endoscopy.

Spindle cell carcinoma of the esophagus containing both carcinomatous and sarcomatous elements is rare, accounting for approximately 1- 2% of all esophageal neoplasms. Terms used to describe this lesion include carcinosarcoma, pseudosarcoma, polypoid carcinoma, pseudosarcomatous squamous cell carcinoma and spindle cell variant of squamous cell carcinoma. Spindle cell carcinomas were originally classified as carcinosarcomas or pseu- dosarcomas, depending on the morphology and bilologic behavior of the particular lesian. However, pseudosarcoma and carcinosarcoma appear to be the same pathologic entity with varying degrees of anaplastic spindle cell metaplasia of the carcinomatous portion of the tumor. Thus, these lesions have been clsssified together as spindle cell carcinomas. A 59 year-old man who experienced weight loss for 4 months was hospitalized as a result of suffering from dysphagia for 2 months. A diffuse bulky protruding mass with superficial ulceration and easy friability on 25 to 35 cm from the incisors, which invaded the right intermediate bronchus and involved the right paratracheal and subcarnial lymph nodes, were obsetved in esophagogram, endoscopy and chest CT. Pathologic finding, including immunoreactivity to cytokeratin and vimentin, was consistent with spindle cell carcinoma. We report a case of spindle cell carcinoma of the esophagus.

The mechanistic functions of 3-deoxysappanchalcone (3-DSC), a chalcone compound known to have many pharmacological effects on lung cancer, have not yet been elucidated. In this study, we identified the comprehensive anti-cancer mechanism of 3-DSC, which targets EGFR and MET kinase in drug-resistant lung cancer cells. 3-DSC directly targets both EGFR and MET, thereby inhibiting the growth of drug-resistant lung cancer cells. Mechanistically, 3-DSC induced cell cycle arrest by modulating cell cycle regulatory proteins, including cyclin B1, cdc2, and p27. In addition, concomitant EGFR downstream signaling proteins such as MET, AKT, and ERK were affected by 3-DSC and contributed to the inhibition of cancer cell growth. Furthermore, our results show that 3-DSC increased redox homeostasis disruption, ER stress, mitochondrial depolarization, and caspase activation in gefitinib-resistant lung cancer cells, thereby abrogating cancer cell growth. 3-DSC induced apoptotic cell death which is regulated by Mcl-1, Bax, Apaf-1, and PARP in gefitinib-resistant lung cancer cells. 3-DSC also initiated the activation of caspases, and the pan-caspase inhibitor, Z-VAD-FMK, abrogated 3-DSC induced-apoptosis in lung cancer cells. These data imply that 3-DSC mainly increased mitochondria-associated intrinsic apoptosis in lung cancer cells to reduce lung cancer cell growth. Overall, 3-DSC inhibited the growth of drug-resistant lung cancer cells by simultaneously targeting EGFR and MET, which exerted anti-cancer effects through cell cycle arrest, mitochondrial homeostasis collapse, and increased ROS generation, eventually triggering anticancer mechanisms. 3-DSC could potentially be used as an effective anti-cancer strategy to overcome EGFR and MET target drug-resistant lung cancer.
