OBJECTIVES: The aim of this study was to evaluate the psychological characteristics of the patients with bruxism by Minnesota Multiphase Personality Inventory(MMPI). METHODS: MMPI was administered to 87 patients(46 bruxism group and 41 control group) who had visited a local dental clinic from January to August 1998. RESULTS: The bruxism group had a higher score than control group in Masculinity-Femininity(Mf) scale. There were no differences between bruxism group and control group on the distribution of Depression(D), Psychopatic Deviate(Pd), Paranoia(Pa), Psychasthenia(Pt) scales. The bruxism group with the family history showed higher score than the bruxism group without family history in Pd scale. Male bruxism group had a higher score than female bruxism group in Defensiveness(K) scale and female bruxism group had higher score than male bruxism group in Pa scale. The bruxism group of clenching type had higher score than the bruxism group of mixed type in Social Introversion(Si) scale. There were no differences in MMPI score between those who had and did not have symptoms such as masticatory musle pain, neck pain and headache. CONCLUSION: It is concluded that individualized approach may be effective to the evaluation of psychological disturbances which might be related to sex, family history and, type of bruxism, while we did not find significant differences in personality charateristics between the bruxism and control groups.

PURPOSE: The purpose of this study was to evaluate the safety, feasibility and effectiveness of an endoluminally-placed bifurcated stent-graft (Vanguard) for the treatment of infrarenal abdominal aortic aneurysm (AAA). METHODS: Transluminal endovascular stent-graft placements were attempted in 29 patients (28 male, mean age 69+/-7 years) with AAAs involving the common iliac arteries from Aug. 1997 to Jan. 1999. Endovascular therapy was performed in the cardiac catheterization laboratory with epidural anesthesia. One side of the femoral artery was opened by surgical cutdown for the bifurcated stent-graft entry and the other side was punctured percutaneously for the straight stent-graft. Computed tomography and/or intraarterial angiography were performed during an average follow-up of 10 months (2-18 months). RESULTS: Primary success rate was 75.9% (22 of 29 patients) and the overall success rate was 79.3% with successful correction of one perigraft leak. Twenty patients (69.0%) had significant coronary artery disease. There were two technical failure cases, the one was tortuous iliac vessel with spasm, the other was disconnection of the stent-graft connecting portion. Complications related to procedure occurred in 13.8% of patients (4 of 29 patients) and two of these four patients had procedure-related mortality because of acute renal failure following contrast overdose and sepsis after operation. CONCLUSIONS: Endovascular treatment of infrarenal AAA with bifurcated stent-graft (Vanguard<0A397>) is effective, feasible and relatively safe. However, further investigation for the outcome, complication and long-term follow-up are needed.

BACKGROUND: Hospital-wide surveillance showed an up to 9% increase in the incidence rate of the nasal transmission of methicillin-resistant Staphylococcus aureus (MRSA) among health care workers (HCWs) in a tertiary care hospital where MRSA is endemic. The purpose of this study was to investigate the knowledge of and attitude towards nasal transmission of MRSA and hand-washing practice among HCWs and determine the behavioral factors associated with the nasal transmission of MRSA. METHODS: In a 750-bed tertiary care hospital, nasal swabs from HCWs were obtained, and questionnaires with 25 questions were distributed to HCWs who were divided into 2 different groups: MRSA carriers and non-carriers. The questionnaires focused on the HCWs' knowledge about the mode of MRSA transmission and precautions against MRSA infection and their self-reported compliance for hand hygiene. RESULTS: The total number of respondents for the surveillance culture and survey were 253 (51 MRSA carriers and 202 non-carriers). There was significant difference between the 2 groups on the knowledge of precautionary measures used for the MRSA patients in the hospital (P=0.026). Compared to the MRSA carriers, the non-carriers washed their hands significantly more frequently after ventilator care (P=0.004) and used more alcohol sanitizers (P=0.023). However, no significant difference was observed in hand-washing practices of both the groups before the medical procedures, their knowledge about the mode of transmission of MRSA, and the duration of hand washing. CONCLUSION: Non-carriers replied more accurately to the questions on knowledge about the management and treatment of MRSA, and they considered interventions such as surveillance cultures and questionnaires to be an effective method in lowering the incidence of nosocomial infections. Compared to the MRSA carriers, the non-carriers showed higher hand-washing compliance.

BACKGROUND: Total occlusion of the infrarenal abdominal aorta is a very rare disease in clinical practice. The clinical outcome may be poor unless management is attempted promptly. Surgical bypass has been recommended as the treatment of choice for these lesions. However, there was relatively high surgical mortality and morbidity associad with aorto-bifemoral bypass graft in patients with other systemic disease, especially coronary artery disease. As a result, the use of, thrombolysis with percutaneous transluminal angioplasty (PTA) has recently been extended to this disease as an alternative method to surgery. PTA is technically simpler with less morbidity and mortality than surgery.We report our experience with thrombolysis and balloon angioplasty of total aortic occlusion in 14 patients between March 1991 and December 1996. METHODS: Fourteen patients, whose mean age was 59+/-13 years (11 male, 3 female), serve as the study's patients. Aortography was introduced via transbrachial artery. The end hole multipurpose catheter with guidewire was introduced into the thrombotic portion of the total occlusion. Urokinase was infused into the thrombus through the catheter if there were no contraindications. in sysremic thrombolysis. Thrombolytic therapy was continued until the thrombi was resolved and flow was restored. Balloon dilatation was followed in residual stenotic lesions. Stents were implanted in case of suboptimal results after ballooning. RESULTS: Clinical findings were resting leg pain in 6 patients, gangrene in 5 patients, and claudication in 3 patients. The causes of aortic occlusion were thromboembolism in 4 patients and thrombosis of an atherosclerotic aorta in 10 patients. Location of obstruction was below the renal artery in all cases. The clinical outcome of interventional therapy was successful in all cases except one patients. Operative treatment was undertaken in 2 cases because they could not received thrombolytic therapy due to contraindication and complication of thrombolytic therapy (gastrointestinal bleeding). Near normal revascularization was achieved in 3 patients by thrombolytic therapy only. PTA was performed at the stenotic after thrombolytic therapy in 4 patients. Stenting were performed at the stenotic sites after balloon dilatation in another 4 patients. There was bleeding complication in one case. CONCLUSIONS: Interventional therapy such as thrombolytic therapy with PTA is an effective and safe treatment modality for abdominal aortic total occlusion in selected cases. These techniques were very useful in some high risk patients who received surgical bypass procedures.

The management of LcP disease is dependent on the prognosis yet. This may be difficult to predict for the individual child, particularly at the onset of the disease when radiological sign may be minimal. But some form of conservative treatment is generally commenced before the prognosis become apparent. The purpose of this study was to determine the validity of Catterall's grouping and value of other radiological and clinical factors in predictiong prognisis and also the correlation between the clinical and radiological results at the conclusion of the pathological precess in LCP disease. Between the clinical and radiological results at the conclusion of the pathological process in LCP disease. Between June 1986 and July 1995, 64 childrens with LCP disease were tearted in Kyungpook University Hospital, 44 hips of 40 childrens who had adequate clinical and radiological data were reviewed. The average follow-up period was 5.4 years. The results obtained were followings: 1.The mean age at first visit or diagnosis was 6.7 years. 2. Of 40 childrens, 4 childrens had bilateral involvement. Boys were more predominat. 3. The degree of uncovering of femoral head and medial joint space at the presentation seemed to be prognostic factor for the end results. 4. Catterall & lateral pillar classification seemed to be difficult at presentation of the disease but also an important guide to determine the prognosis.

A accidental spills of phenol(100%) to the river Nakdong with subsequent contamination of the tap water for about two million consumers in Taegu city of Korea were occurred in March 1991. A historical cohort study of 6,913 individuals was undertaken to determine the associated with illness. Population subjects were divided into two groups of exposed and unexposed. Exposed subjects were reported to be phenol associated symptoms significantly higher than those in a nearby unexposed area(39.6% vs 9.4%, p<0.01). Especially, in the related symptoms, highly significant differences were noted in the number of subjects reporting gastrointestinal illness such as nausea, vomiting, diarrhea, or abdominal pain. During the accident, study subjects who experienced peculiar taste or odor in the tap water were significantly higher in the exposed areas(92% vs 34.3%). Chlorophenols formed from chlorination of water may have aggravated the problem.

Patients with aortic root disease, frequently seen in Marfan syndrome have progressive dilatation of the aortic sinuses and dilatation and distortion of the aortic annulus, leading to aortic incompetence. They are currently treated with composite graft replacement of the ascending aorta and aortic valve and reimplantation of the coronary arteries. Recently, we experienced an aortic root replacement with aortic valve preservation in a patient with annuloaortic ectasia. The ascending aorta and sinus was excised except the aortic annulus and aortic valve. The aortic valve was reimplanted inside of a collagen-impregnated tubular Dacron graft. The coronary arteries were also reimplanted. The patient was followed up for six months and reevaluated with the echocardiography. Postoperative Doppler echocardiography revealed normal aortic valve function. With this technique, it is possible to preserve the native aortic valve if the aortic leaflets are anatomically normal.

A 41-year-old female was admitted to our hospital for self-audible wheezing sound and dyspnea. On past history, she has been suffered from chest discomfort, and treated recurrently by other hospitals. But, there was no symptomatic improvement. A stridor and mixed wheezing sound was auscultated on whole lung field. PFT revealed fixed type or variable intra- & extra-thoracic air way obstructive pattern. By bronchoscopy & bronchogram, we found web-like structure on the distal trachea. A bronchoplasty was performed and the post-operative PFT showed slight improvement & she had no more complaints.
