BACKGROUND: Despite improvement of mortality in acute myocardial infarcrtion, high mortality rate associated with cardiogenic shock remains essentially unchanged. We have reviewed our result of coronary intervention in 15 patients and found relative survival advantage. METHODS: Between Sep. 1992 and Aug. 1995, 15 consecutive patients(M. 10, F. 5) with cardiogenic shock in acute myocardial infarction were treated with coronary intervention using ballon PTCA. IABP was inserted in all patients prior to PTCA. RESULTS: 1) Most commonly found infarct related artery was left anterior descending artery(11) followed by right coronary artery(3) and left main coronary artery(1). 2) Successful reperfusion rate was 86.7%(13/15), and in-hospital mortality rate was 26.7%(4/15). 3) In-hospital mortality was higher in elderly patients compared with less than 70yaer old patients(0%(0/11)vs. 75.0%(3/4)(P < 0.05). 4) Mortality rate was lower in single vessel disease than multivessel disease(11.1%(1/9) vs. 50%(3/6) p<0.05). CONCLUSION: Although this study is uncontrolled, the date suggest that urgent coronary intervention for improving coronary perfusion may reduce mortality of acute myocardial infarction complicated by cardiogenic shock, particularly with single vessel disease and young age group.

Pheochromocytoma is a hazardous and dramatic cause of hypertension. This potentially lethal neoplasm originates in most cases in the adrenal medulla and less frequently in the cells of the extraadrenal paraganglion system which are disseminated along the paravertebral axis from the pelvis to the base of the skull. The organ of Zuckerkandl is paraganglia lying the abdominal aorta with highest incidence in the region of the inferior mesenteric artery and usually degenerate shortly after birth. In the literature, and additional one case of pheochromocytoma arising from the organ of Zuckerkandl associated with intracerebral hemorrhage which was treated recently in the Kyung Hee University Hospital is presented in this report.

OBJECTIVES: To identify the importance of preventing tuberculosis for HIV (Human Immunodeficiency Virus) infectees and to monitor their management of health, we investigated the proportion of HIV-TB (Tuberculosis) deaths among the HIV deaths and its related factors. METHODS: Data for HIV deaths from 2002 to 2010 was acquired from Statistics Korea, after which the HIV deaths were reclassified into HIV-TB deaths or other deaths according to the KCD (Korean Classification of Diseases). We analyzed the proportion of HIV-TB deaths among HIV disease deaths and the relationship between HIV-TB deaths and related variables such as sex, age, educational level, marital status, etc. RESULTS: There were 774 HIV deaths in South Korea between 2002 and 2010. TB was the main cause of death in 10.1% of all HIV deaths. The total proportion of HIV-TB deaths was 10.1% but its proportion reached 16.3% between 2005-2007 and then decreased to 4% in 2010. Also, the proportion of HIV-TB deaths was significantly high in the young age groups, but its proportion was significantly low in married groups and well educated groups (p<0.05). CONCLUSIONS: The result implies that the policy that takes care of HIV infectee regarding TB prevention has been getting systemized on a national scale. Also, HIV-TB deaths have been affected by social factors such as education and marriage status.

The change of venous capacitance has an influence on venous return to the heart and cardiac output, and causes the alteration of preload, cardiac filling pressure and myocardial wall tension. Venous capacitance is assesed by measuring the mean circulatory filling pressure (MCFP), and MCFP is measured during brief periods of circulatory arrest produced by inflating an indwelling balloon in the right atrium It is important to know the effects of vasodilator and anesthetic drugs on venous capacitance. Therefore, this study was performed to know the effects of nitroglycerin and diltiazem on venous capacitance in rats. Rats were anesthetized with ketamine 125 mg/kg given intraperitoneally and added 10 mg/kg every 30 minutes. Their mean arterial pressure (MAP) was lowered to 60 mmHg by intravenous injection of 0.82+/-0.36 mg/kg nitroglycerin and/or 6.7+/-1.5 mg/kg diltiazem. Hemodynamic parameters such as MAP, heart rate, central venous pressure and MCFP were measured before and after drug-injection. Hemodynamic values measured before drug-injection in two groups were little differences statistically. However, the MCFP of nitroglycerin was significantly decreased (p<0.01) from 7.3+/-0.61 mmHg to 5.4+/-0.58 mmHg after drug-injection, and that of diltiazem was not significantly changed from 7.1+/-0.54 mmHg to 6.9+/-0.63 mmHg. The results suggested that nitroglycerin was predominantly a venous dilator in terms of MCFP but diltiazem had little effect of venodilation.

PURPOSE: The aim of this study was to assess the feasibility and safety of laparoscopic multivisceral resection of colorectal cancer adherent to adjacent organs. METHODS: We reviewed retrospectively 32 patients undergoing elective laparoscopic multivisceral resection for colorectal cancer adherent to adjacent organs between June 2003 and May 2009. Survival curves were generated by Kaplan-Meier method. RESULTS: The median age of 32 patients was 73 years. In 10 of 17 rectal cancer patients (59%), neoadjuvant chemoradiation was performed. All the surgeries were completed laparoscopically. The postoperative complications occurred in 21.9% and there was no operative mortality. The median length of hospital stay was 15.5 days. In 23 of 32 patients (72%), the resection was considered curative. Median follow-up period of all patients and curatively resected patients was 22 (range, 2~65) months, 34 (range, 4~65) months respectively. Local recurrence rate, the 3-year overall survival rate and the 3-year disease free survival rate of 23 curatively resected patients was 4.3%, 92.9% and 84.4%, respectively. CONCLUSION: Laparoscopic multivisceral resection is feasible and safe in highly selected patients with colorectal cancer adherent to adjacent organs. Further validation is needed.

A 72-year-old diabetic male patient with high grade fever, right upper quadrant abdominal pain and Klebsiella pneumoniae septicemia is reported. He suffered from high fever and abdominal pain in spite of aspiration of liver abscess and antibiotic treatment. A few days later, we found a palpable pulsating abdominal mass on physical examination. Computed tomography and angiography revealed infected abdominal aortic aneurysm associated with pyogenic liver abscess. He was treated by antibiotics and Endovascular stent without surgical resection. He improved without complications and has been followed-up after discharge with excellent condition. To our knowledge, this is the first case of infected abdominal aortic aneurysm as a septic metastatic lesion secondary to liver abscess.

STATEMENT OF PROBLEM: In the partially edentulous patients, removable partial dentures have been working as a important treatment modality. Clasps, a kind of direct retainers, received some amount of stresses during the insertion and removal of partial denture on the abutment tooth. PURPOSE: The study is to investigate stresses of the different clasps. MATERIAL AND METHODS: In order to investigate the degree of stresses, maxillary partial edentulism (Kennedy Class II, modification 1) was assumed and removable partial dentures were designed on it with three kinds of metallic materials; cobalt-chromium alloy, type IV gold alloy and commercially pure (c.p.) titanium. Aker's clasp was applied on the left second molar, RPA (mesial rest-proximal plate-Aker's) clasp was on the left first premolar and wrought wire clasp was on the right first premolar. Three dimensional, non-linear, dynamic finite element analysis method was run to solve this process. RESULTS: 1. Cobalt-chromium alloy had the highest von Mises stress value and c.p. titanium had the lowest one irrespective of the types of clasps. 2. In the Aker's clasps, stress on the retentive tips was shown shortly after the appearance of stresses of the middle and minor connector areas. These time lag was much shorter in the RPA clasps than in the Aker's clasp. 3. In general, retentive tips of wrought wire clasps had much less amount of stress than other clasps. CONCLUSION: The amount of stress was the highest in the RPA clasp and the lowest in the wrought wire clasp, in general.

PURPOSE: The purpose of this study is to assess the periopertive morbidity and mortality rates in relation to the principal variables in aged patients who undergo laparoscopic colorectal resection. METHODS: From March 2001 to March 2006, the prospective laparoscopic colorectal resection database was used to identify 233 patients. Among them, 132 were 70 years of age or older and they were classified as the aged group. 101 were younger than 70 years of age and they were classified as the younger group. RESULTS: Comorbidity was more common in the aged group than in the younger group (67.4% and 53.5%, respectively) (P=0.030). There were higher ASA scores in the aged group (I: 2.3% II: 68.2% III: 29.5%) than in the younger group (I: 27.7% II: 56.4% III: 15.8%) (P<0.0001). There was a higher postoperative complication rate for the aged group than for the younger group (25.0% and 8.9%, respectively) (P=0.002). Only one case of mortality (0.8%) was found in the aged group. The period of the postoperative hospital stay was longer for the aged group than that for the younger group (21.9+/-3/416.3 days and 16.3+/-3/48.1days, respectively) (P= 0.002). For the aged group, univariate analysis revealed that the operative procedure, disease, the T stage and the operation time were significant variables for the postoperative complications, and multivariate analysis identified the operation time as an independent variable faor the postoperative complications. CONCLUSION: More prudent care is needed to prevent postoperative complications for the aged patients who undergo laparoscopic colorectal resection, and particularly for those who can be expected to have a longer operation time.
