A clinical study was made of 14 cases of distal rectal cancer treated at the Department of Surgery, St. Mary's Hospital, Catholic University Medical College, from January 1995 to April 1996. The patients were treated in a modified Thomas Jefferson program and received high doses of preoperative radiation followed by a sphincter saving procedure. The results are as follows: 1) There were 5 male patients (35.7%) and 9 female patients(64.3%). There was also a large number of patients in their 50s and 60s. 2) The preoperative pathologic type was a moderately differentiated adenocarcinoma. 3) Rectal bleeding was the most common symptom, followed by tenesmus, constipation, anal pain, and a tarry stool. 4) At diagnosis, the Thomas Jefferson (T.J.) system was used for the clinical stage of the patients. The clinical stage of disease showed a preponderance of T.J. stage I (10 patients), T.J stage II, III, and IV occurred in 2, 1, and 1 patient, respectively. 5) The most common site was 0-3 cm above dentate line (8 patients), followed by 4-6 cm (5 patients) and > 7 cm (1 patient) above the dentate line. 6) The complications after preoperative radiation therapy were diarrhea (3 patients) and perianal dermatitis (5 patients). 7) After preoperative radiation therapy, one case showed pathologic complete remission. 8) The procedure was a Transanal Abdominal TransAnal proctosigmoidectomy and coloanal anastomosis (TATA) in 11 patients, a low anterior resection in 1 patient, an abdominal perineal resection in 1 patient, and a colostomy in 1 patient. 9) The pathologic stage showed a preponderance of Duke's B2 and B1; 5 were B2, 4 were B1, 3 were C2, 1 was D, and 1 was O. 10) The postoperative complications after colostomy repair in TATA were frequent defecation, tenesmus, anal pain at defecation, and rectovaginal fistulas which subsided 3 months after colostomy repair.

Pacemaker implantation for patients with mechanical tricuspid valve is quite challengeable because lead insertion through prosthetic tricuspid valve may cause valve dysfunction or lead impingement. Also complications due to interrupt of anticoagulation should be considered. A 65 years old woman received AAI (atrium paced, atrium sensed, inhibited) pacemaker for sick sinus syndrome and mechanical mitral valve replacement for severe mitral steno-insufficiency at the same time 16 years before. She needed to undergo mechanical tricuspid valve replacement (TVR) because of severe tricuspid regurgitation despite of medical therapy. Complete atrioventricular block developed during the TVR operation and it was not recovered even after several days of temporary pacing. We decided left ventricular pacing through coronary sinus because ventricular lead could not pass mechanical tricuspid or mitral valve and also planned to continue oral anticoagulation therapy. We could find a place where high pacing output did not pace phrenic nerve with acceptable sensing, pacing threshold. The patient recovered well without any periprocedural complications. Left ventriclcular pacing lead implantation through coronary sinus without interruption of anticoagulation can be an alternative to epicardial pacing for patients with mechanical tricuspid valve.

OBJECTIVE: The purpose of this study was to define the effect of the changes of left ventricular ejection fraction (LVEF) on long-term major adverse cardiac events (MACEs) in patients with acute myocardial infarction (AMI). METHODS: Clinical analysis was performed on 1,188 AMI patients who completed follow- up 2-dimensional (2D) echocardiography after one year and clinical follow-up for 5 years. These patients were divided into three groups according to the LVEF change ratio: group A [increased LVEF change ratio, N=626], group B [decreased LVEF change ratio<20%, N=414], group C [decreased LVEF change ratio≥20%, N=148]. RESULTS: Initial low LVEF group and normal LVEF group showed no differences in MACEs. The mean initial and follow-up LVEF were 54.4±12.2% and 60.4±12.3% in the group A, 54.6±13.0% and 47.9±12.1% in the group B, and 56.5±12.6% and 39.9±11.6% in the group C (p=0.71). Total MACEs occurred in 62 (9.9%) patients in the group A, 83 (20.0%) patients in the group B, 44 (29.7%) patients in the group C during 5-year clinical follow-up (p=0.01). Initial low EF (<45%) was not a risk factor for long-term MACEs (Odd ratio (OR), 1.686; 95% confidence index (CI), 0.861-2.862, p=0.065), but the LVEF change ratio was a strong risk factor for long-term MACEs (OR, 3.731; 95% CI, 2.039-6.828, p=0.001). MACE-free survivals of patients with initial low LVEF and patients with low LVEF during follow-up period showed no significant differences (p=0.731). CONCLUSION: Initial low LVEF is not a predictor of long-term MACEs, but the decreased LVEF ratio during follow-up period is a strong predictor of long-term MACEs.

BACKGROUND AND OBJECTIVES: Platelet activation and aggregation, with resultant arterial thrombus formation, play pivotal roles in the pathophysiology of acute coronary syndrome (ACS). The efficacy of tirofiban, a specific inhibitor of the platelet glycoprotein IIb/IIIa receptor, combined with heparin, or low molecular heparin (LMWH), in the management of ACS were evaluated. SUBJECTS AND MEHTODS: One hundred seventeen patients (60.8+/-10.9 years, 76 male), with unstable angina or non-ST elevation myocardial infarction, who had ST-T changes and elevated troponin, were divided into 4 groups : Group I (n=30 : heparin alone), Group II (n=28 : LMWH, dalteparin alone), Group III (n=29 : tirofiban combined with heparin) and Group IV (n=30 : tirofiban with LMWH). The major adverse cardiac events (MACE) among the 4 groups, during 6-month clinical follow-ups, were compared. RESULTS: Percutaneous coronary intervention, or a coronary artery bypass graft, was performed in 23, 19, 19 and 22 patients from Groups I, II, III and IV, respectively (p=0.87). A minor bleeding complication developed in 2 (6.7%), 1 (3.6%), 1 (3.4%) and 2 patients (6.7%) in groups I, II, III and IV, respectively (p=0.79). During the six-month follow-up MACE occurred in 7 (30.4%), 6 (31.6%), 3 (15.8%) and 4 patients (18.2%) in groups I, II, III and IV, respectively (p=0.02 : Group I and II vs. Group III and IV). CONCLUSION: Tirofiban combined with LMWH is safe and may improve the long-term prognosis of patients with ACS.

BACKGROUND: Rheumatoid arthritis(RA) is a systemic disease not infrequently involing the heart. It has been known that pericardial effusion, most commonly observed cardiac abnormality in patients with RA, and other cardiac manifestations such as conduction disturbances, valve thickenings, and enlargement of left atrium or aorta are associated with RA. We have determined the nature and extent of cardiac manifestations of RA in comparison with those of control group by echocardiographic examination. METHOD: 27 patients with RA(4 males and 23 females, mean age=47 +/-13 years) and 22 control subjects(3 males and 19 females, mean age+43 +/- 11 years) were randomly selected. Standard two-dimensional, M-mode and doppler echocardiographic examination were done on each group of subjects. RESULTS: 1) Pericardial effusions were more commonly detectd in patients with RA than control group(55.6% vs 22.7%, p<0.01). There were no significant differences in the amount of pericardial effusion according to the duration and the stage of RA. 2) Thickness of each cardiac valve was thicker in patients with RA than control group. But, there were no statistical significance between them. 3) The left ventricular mass index(LVMI) and the diameter of aorta showed a trend to increase in patients with RA(109.5 +/-28.0 g/m(2) vs 94.2 +/-24.6 g/m(2), p=0.054). 4) The diameter of left atrium was more lager in patients with RA(35.1 +/- 4.0mm vs 31.6 +/- 4.5mm, p=o.005). 5) The E/A ratio of mitral valve was statistically significantly lower in patients with RA(RA:control=1.2 +/- 0.5 : 1.7 +/- 0.4, p=0.01). CONCLUSION: The asymptomatic patients with RA more frequently show cardiac abnormalities such as pericardial effusion, valve thickening, decrease of E/A ratio than control group. So two-dimensional echocardiography is necessary for early, noninvasive and accurate evaluation of asymptomatic cardiac abnormalities in patients with RA.

Stress cardiomyopathy (SCMP) is characterized by a transient left ventricular dysfunction associated with apical ballooning and compensatory hyperkinesias of the basal segments after emotional or physical stress, but inverted or mid-ventricular variants of SCMP have also been described. Although catecholamine excess has been suggested as a possible pathophysiologic mechanism of SCMP, the etiology of SCMP is still unknown. Here, we report a case of inverted type of SCMP with clinical presentation mimicking acute coronary syndromes. The cause or precipitating stressor was unclear initially, but pheochromocytoma has been demonstrated as a cause of SCMP during clinical follow-up at out-patient clinic in the present case. Catecholamine-producing tumors should be included in the evaluation or management of SCMP, even though initial clinical manifestations are not suggestive for pheochromocytoma.

PURPOSE: To evaluate changes in quality of life (QoL) in patients with neurogenic bladder treated with clean intermittent catheterization (CIC), who changed from a multiple use catheter (MUC) to single use catheter (SUC). METHODS: The Modified Intermittent Self-Catheterization Questionnaire (mISC-Q) was used to determine potential changes in patients'QoL as a result of switching from MUC to SUC. The mISC-Q consists of questions within four categories: ease of use, convenience, discreetness, and symptomatic benefit. Answers were graded as Strongly agree (+2), Agree (+1), Not sure (0), Disagree (−1), and Strongly disagree (−2). Overall patient QoL, as well as by sex, disease (presence of augmentation cystoplasty), and catheterization route (via urethra or urinary diversion), were analyzed. RESULTS: Thirty-eight patients (21M:17F; mean age: 21.7±5.3 y) submitted questionnaires. For ease of use, SUC was significantly better than MUC (score: 0.364, P=0.002) in all patients. Patients with catheterization via the urethra showed significant favor for SUC in ease of use (score: 0.512, P<0.001) and convenience (score: 0.714, P=0.011), but patients with catheterization via the abdominal stoma of urinary diversion gave negative scores in all categories, though no categories were significant. CONCLUSION: This study suggested that changing from MUC to SUC may lead to improvements in QoL, especially regarding ease of use. This benefit was clearly found in patients with catheterization via urethra rather than abdominal stoma of urinary diversion.
