PURPOSE: In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. MATERIALS AND METHODS: Patients with narrow range of age (21-25. mean 22.8+/-1.3, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon tear, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed 21.2+/-7.3wks after trauma. RESULTS: According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight bearing patterns - increased contralateral sole at P and B - were revealed in 7(58.3%). CONCLUSION: Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.

A 38 year old woman presented with two week history of cough, progressive dyspnea, orthopnea and pedal edema. She had previously been in excellent health with the exception of surgery five years ago for tumor of the right thigh. The histopatihologic diagnosis was chondrosarcoma. Her clinical course was characterized by rapid aggrevation of dyspnea and eddema unresponsive to conventional managements for congestiove heart failure. Transesophageal echocardiogram showed dleft atrial mass growing from pulmonic vein. To our knowledge, cardiac metastasis from chondrosarcoma is rare and we report this is the first case of chondrosarcoma metastatic to the heart in Korea.

The coronary arteriovenous fistula (CAVF) is a rare congenital anomaly but constitutes the most common hemodynamically significant coronary artery anomaly. Transcatheter embolization is as an effective alternative to surgery even though procedure may be complicated by migration of the coil into peripheral vessels or pulmonary arteries. To our knowledge, the association of CAVF with Turner syndrome was not reported. We report a case of successful coil embolization of CAVF using a complex, helical-fibered platinum coil in patient with Turner phenotype with 46,XX.

BACKGROUND: The purpose of this study is to evaluate the immediate survival, complication and follow-up results of aortic dissection and to analyze the risk factors that determine the prognosis after aortic dissection. METHODS: 29 patients(M : 12, Age : 59.0+/-11 yrs) with aortic dissection were reviewed retrospectively. Any dissection involving the ascending aorta was classified as proximal dissection and the dissection was considered to be acute if time from clinical onset of the dissection to admission was less than 2 weeks. The immediate survival rate and follow-up results of aortic dissection was compared by type, onset and mode of treatment. RESULTS: 1) The studied patient were 29(Acute onset : 24, Proximal type : 14) and 17 patients(Proximal type : 14) were surgically treated. 2) Five of 10 patients with proximal dissection and 4 of 12 patients with distal dissection, who were managed by medical treatment, died, and 1 of 4 patients with proximal dissection and none of 3 patients with distal dissection, who were managed by surgical treatment, died at hospital. There was no significant statistical difference in mortality according to type, onset and mode of treatment. 3) Nine of 14 patients with proximal dissection and 8 of 15 patients with distal dissection had one or more complications. 4) The cause of death could be established in 10 patients. The most frequent cause of death was aortic rupture including cardiac tamponade(4 of 6 patients for proximal dissection, 2 of 3 patients for distal dissection). 5) The most of death, 8 of 10 deaths occurred within 2 weeks of onset of disease. there was a good life expectancy for the discharged patient regardless of type, onset and mode of treatment. CONCLUSION: These data showed that there was equivalent outcomes in patients with aortic dissection regardless of type, onset and mode of treatment. But these data would not be applied to general population with aortic dissection because of limited number of the study.

BACKGROUND: Transluminal balloon coronary angioplasty is one of the most widely used therapeutic procedures in the treatment of patients with coronary artery disease. However, restenosis remains a major limitation of percutaneous coronary angioplasty despite extensive efforts to prevent recurrence. We examined the immediate and long-term results of 516 patients (617 lesions) who underwent coronary angioplasty to evaluate the initial success rate, complications, restenosis rate, and the factors affecting initial success and restenosis. METHODS: The coronary angioplasty of 516 patients(M/F : 388/128, mean age : 57 years), 671 lesions was done with conventional technique and follow-up coronary angiogram was obtained 4 to 6 months after angioplasty in 168 patients. The angiographic restenosis was defined as >50% luminal narrowing in a previously dilated lesion, and the clinical restenosis defined as the recurrence of typical angina and/or positive tests of treadmill test, or thallium scintigraphy during follow-up period. RESULTS: 1) The coronary angioplasty was successful in 459 of 516 patients(89%), 604 of 671 lesions(90%). The success rate was significantly lower in subgroups with type C lesion(52.2%, p<0.001), right coronary artery (83.7%, p<0.05) and <3.0mm of size of lesion(81.4%, p<0.001). 2) The procedural complications were as follows : intimal dissection in 143 lesions(21.3%) including acute closure in 9 lesions(1.3%), emergency bypass surgery in 6 patients(1.2%), myocardial infarction in 9 patients(1.7%), rupture of coronary artery in 2 patients, air embolism in 1 patient, and death in 1 patient(0.19%). 3) The causes of the procedural failure(n=57 patients) included guidewire passage failure in 27, balloon passage failure in 4, catheter engagement failure in 1, acute closure in 7, coronary artery rupture in 2, and suboptimal result in 16 patients. 4) Clinical follow-up was obtained in 455 patients for a mean follow-up duration of 13.2months and clinical restenosis rate was 31%(141/455). The repeat coronary angiogram was performed in 168 patients(209 lesions) for a mean follow up duration 5.4month and demonstrated 48%(100/209) angiographically restenosis rate. The clinical restenosis rate was significantly lower in subgroups with <10% of residual stenosis(18.9%, p<0.05), left circumflex coronary artery(18.5%, p<0.05). 5) The restenosis following angioplasty(n=100 lesions) was treated with repeated PTCA in 57, Stent(Palmaz-Schatz) in 6, DCA in 3, elective CABG in 9, and medication in 25. 6) During the clinical follow-up, there were nonfatal myocardial infarction in 4 patients. CONCLUSION: 1) The coronary angioplasty is an effective treatment for revascularization that has a high success rate, low incidence of complications and excellent long-term survival. 2) The restenosis rate was affected by residual stenosis which suggests that the implication of minimal residual stenosis is the most important determining factor to reduce the restenosis rate after angioplasty.

OBJECTIVES: To examine whether the nursing practice environment at the hospital-level affects the job satisfaction and turnover intention of hospital nurses. METHODS: Among the 11 731 nurses who participated in the Korea Health and Medical Workers' Union's educational program, 5654 responded to our survey. Data from 3096 nurses working in 185 general inpatient wards at 60 hospitals were analyzed using multilevel logistic regression modeling. RESULTS: Having a standardized nursing process (odds ratio [OR], 4.21; p<0.001), adequate nurse staffing (OR, 4.21; p<0.01), and good doctor-nurse relationship (OR, 4.15; p<0.01), which are hospital-level variables based on the Korean General Inpatients Unit Nursing Work Index (KGU-NWI), were significantly related to nurses' job satisfaction. However, no hospital-level variable from the KGU-NWI was significantly related to nurses' turnover intention. CONCLUSIONS: Favorable nursing practice environments are associated with job satisfaction among nurses. In particular, having a standardized nursing process, adequate nurse staffing, and good doctor-nurse relationship were found to positively influence nurses' job satisfaction. However, the nursing practice environment was not related to nurses' turnover intention.

BACKGROUND: A clinical trial was done to evaluate the antihypertensive efficacy and side effects of amlodipine, a new long-acting calcium antagonist, in patients with mild to moderate essential hypertension. METHODS AND RESULTS: 1) The study patients consisted of 18 men and 12 women, and the mean age was 49 years. Amlodipine monotherapy (5-10mg) was continued for 12 weeks. 2) Blood pressure dropped significantly in 4 weeks and in 8 weeks, and well maintained throughout the study period. The mean-pressure drop was 32.9/20.8mmHg after 12 weeks. 3) Heart rate did not change significantly with amlodipine therapy. 4) Optimal dose for effective pressure-drop was 10mg in 57% of patients. Overall good antihypertensive effect was achieved in 83% of patients. 5) All of the laboratory parameters including blood chemistry, glucose, lipid and electrolytes did not change significantly after 12 weeks. 6) Side effects were mild in nature(gastrointestinal discomfort in 3, dry mouth in 1, weakness in 1, dizziness in 1 and headache in 1 patient). CONCLUSION: Amlodipine monotherapy with 5 to 10mg once a day regimen is effective and well tolerated in the patients with mild to moderate essential hypertension.

BACKGROUND: Follow-up angiographic study was performed in patients who underwent successful coronary artery stenting(Palmaz-Schatz) to native coronary arteries, to evaluate the restenosis rate and angiographic features. METHOD: Follow-up angiography was done in 6 months after coronary arteries stenting in 16 of 22 patients(follow-up rate : 73%) regardless of symptom recurrence or the result of exercise treadmill test. RESULTS: 1) Total 26 Palmaz-Schatz stents were implanted in 26 patients with coronary stenosis : primary, elective stenting in 19, bail-out procedure in 4 and restenosis after prior coronary angioplasty(PTCA) in 4 patients. The morphological characteristic of the leisons were type A in 1, type B in 20 and type C in 5. 2) Coronary stenting was successful in all patients and no significant procedure-related cardiac event occurred. Subacute closure in the stent and bleeding complication developed in minority of patients. 3) The overall restenosis rate in six months was 31%. 4) The diameter stenosis of the lesion in the patients without restenosis was 94% before stenting, 6% immediately after stenting and 26% in 6 months. CONCLUSION: Coronary artery stenting is a safe and useful interventional procedure which can be done with low risk even in the complicated leison. The restenosis rate is comparable to conventional PTCA. The long-term outcome of coronary stenting might be more favorable and promising with more selective and strict application of this procedure.
