The isolated coronary ostial stenosis is a lesion of the aortic wall that encroaches on the orifice of the left main coronary artery, atherosclerosis is belived to be a common cause and premenopausal female patients are most commonly affected. Stenosis of the left coronary ostium is a critical lesion which requires urgent myocardial revascularization including a surgical intervention because this lesion jeopardizes such a large volume of left ventricular myocardium. We report the case of a patient in whom percutaneous transluminal coronary angioplasty (PTCA) was performed successfully for the stenotic lesion of distal anastomotic site after surgical ostioplasty with autologous pericardium.

A retrospective morphological study was conducted on 1677 lymph nodes which were removed surgically under the diagnosis of gastric carcinoma, breast carcinoma, colonic carcinoma, chronic gastric ulcer, and superficial lymph nodes nuder the diagnosis of reactive follicular hyperplasia at Chosun University Hospital during a period of 5 years from 1980 to 1984. The hematoxylin and eosin stained sections were examined to evaluate for any vascular changes. In selected cases further levels were prepared from the paraffin blocks for Gomori's reticulin stain. The vascular abnormalities were divided into 3 groups, such as hemangiomatoid, pan-nodal vasodilatation and miscellaneous types. The miscellaneous type included the proliferation of smooth muscle which encircled numerous small hilar arteries and veins. The results obtained were as follows: 1) The hemangiomatoid lesions were localized lesions which appeared to be associated with local malignancy, but infrequent in incidence. 2) A more frequent vascular abnormality was pan-nodal vasodilatation, which tend to affect many nodes in a single group and is relatively associated with chronic gastric ulcer. 3) Miscellaneous lesion was nonspecific and appeared both local malignancy and chronic inflammation. 4) All three vascular reactions were somewhat more frequent in female than male.

BACKGROUND: Although surgical angioplasty for isolated coronary ostial stenosis is assumend as an alternative approach to CABG, the clinical features of isolated coronary ostial stenosis, postoperative complications and follow-up angiographic results would have not been well studied. METHODS: We retrospectively studied 24 patients (female : male = 20 : 4, mean age 50.0 +/- 12.3 yr) who underwent surgical angioplasty for isolated coronary ostial stenosis using patch ( 22 fresh autologous pericardium, 2 saphenous vein) during the period of March 1990 through February 1998. Repeat coronary angiography (16 patients) and echocardiography (24 patients) were performed. Aortic regurgitation was evaluated semiquantitatively (Grade I - Grade IV). RESULTS: There were 3 deaths after surgical angioplasty. One death was due to acute coronary dissection perioperatively, the second due to low cardiac output syndrome 2 weeks post-surgery, and the third due to traumatic panperitonitis 10 months post-procedure. Angina recurred in 4 patients and the remaning 18 patients were symptom-free. Repeat angiography (19.3 +/- 20.7 Mo) showed widely patent ostium with excellent run-off except 2 patients (1 distal patch stenosis, 1 ostial restenosis in Takayasu's arteritis). The third symptomatic patient was proven to have coronary spasm by ergonovine test. AR increased in the fourth patient (Grade II -> III) with patent ostium. CONCLUSION: Surgical angioplasty may be feasible and alternative operative method to CABG for isolated coronary ostial stenosis. It should however be noted that postop AR can develop and/or increase. Further investigation is needed to evaluate the clinical significance of the AR.

BACKGROUND: Ross procedure is the pulmonary valve autograft in the aortic valve disease, and its use trends to increase after introduced by Ross in 1967, firstly. The most important point is that it is a permanent valve replacement. It is to be ideal method to the young patient because the graft is a viable tissue to be able to grow, and hemodynamically, most similar to the normal aortic valve, and doesn't need to do anticoagulation therapy due to not having the thromboembolism, but not popular because it has a lot of technical problem and doesn't have the long-term follow-up METHODS: The patients were 8 admitted between October 1997 and October 1998, the age from 15 to 39 ; 6 males and 2 females. The causes of disease were 4 patients of rheumatic disease, 1 of a infective endocarditis with the aortic annular abscess,1 of recurred severe aortic insufficiency 2 years after replacement. Two patients used the homograft and 6 patients switched a diseased aortic valve with the pulmonary autograft. RESULTS: There were no death and the preoperative dyspnea nearly disappeared (NYHA FC III-IV -> I-II). The diastolic diameter of left ventricle decreased significantly when we compared to the previous echocardiography 1 month after the operation, and we observed the mild aortic valve insufficiency in 3 patients, severe in 4, mild pulmonary valve insufficiency in 4, severe in 1, and mild pulmonary valve stenosis in 4. CONCLUSION: The operative death rate of Ross procedure in the aortic valve disease was not higher than the artificial valve replacement. Therefore, if we find the appropriate indication of operation, we can expect better results and think that we should have the long-term follow-up furthermore.

OBJECTIVES: This study examined job satisfaction, empowerment, job stress, and burnout among tuberculosis management nurses and physicians in public healthcare institutions. METHODS: This was a cross-sectional study analyzing survey data collected from 249 nurses and 57 physicians in 105 public health centers, three public tuberculosis hospitals, and one tertiary hospital. The survey questionnaire comprised general characteristics, work-related characteristics, and four index scales (job satisfaction, empowerment, job stress, and burnout). The two-sample t-test was used to estimate the mean differences in the four index scales. Multiple regression analysis was used to determine whether general and work-related characteristics affected the four index scales. RESULTS: The job satisfaction and empowerment scores of the nurses were lower than those of the physicians. Except for the tuberculosis-specialized hospitals alone, the average job satisfaction scores of nurses were higher than those of physicians. Moreover, the nurses reported more job stress and burnout than did the physicians in tuberculosis departments in public healthcare institutions in Korea; in particular, the burnout reported by nurses was significantly higher than that reported by physicians at the National Medical Center. Marital status, nursing position, number of coworkers, the average number of days of overtime work per month, self-rated health, and hospital type were associated with the four index scales. CONCLUSIONS: Overall, nurses were more vulnerable to job stress and burnout than physicians. Reducing the workload of nurses by ensuring the presence of sufficient nursing staff and equipment, as well as by equipping facilities to prevent tuberculosis infections, should be considered priorities.
