BACKGROUND: Brother of the regulator of imprinted sites (BORIS) is a putative new oncogene that is classified as a cancer germline gene; however, its role in the development of cancer is unclear. This study investigated the expression of BORIS in lung cancer and its clinical implications. METHODS: The expression of BORIS messenger ribonucleic acid (mRNA) in the sputum of 100 patients with lung cancer (50 with squamous cell carcinoma, 36 with adenocarcinoma, and 14 with small-cell carcinoma) was evaluated by reverse transcription polymerase chain reaction. RESULTS: The overall expression rate of BORIS in patients with lung cancer was 36.0%: 19 of 50 squamous cell carcinomas (38.0%), 13 of 36 adenocarcinomas (36.1%), and 4 of 14 (28.6%) small-cell carcinomas. There was no significant difference in the BORIS expression according to age, gender, or histologic type. However, the mRNA expression of BORIS was significantly related to the pathologic cancer stage (p=0.004) and lymph node metastasis (p=0.001). The expression of the melanoma antigen gene family A1-6 was not associated with the expression of BORIS. CONCLUSION: Our results suggest that the expression of BORIS might be a negative prognostic factor in lung cancers and implicate BORIS as a molecular target for immunotherapy.

PURPOSE: We analyzed the frequency and characteristics of atherosclerotic plaques in the patients without coronary artery calcification (CAC) by the use of multidetector row CT (MDCT). In addition, we analyzed patients with negative CAC to guarantee the absence of coronary artery disease (CAD). MATERIALS AND METHODS: One hundred-ten patients with a suspicion of CAD and no CAC as detected on 16-slice and 64-slice MDCT were enrolled in this retrospective study. We analyzed the frequency of atherosclerotic plaques. For characterizing the atherosclerotic plaques, location, attenuation, volume, the degree of stenosis, and the remodeling index (RI) were analyzed. RESULTS: Atherosclerotic plaques were detected in 8 patients (7.3%). The plaques were located in the right coronary artery (n=3), left anterior descending artery (n=3), and left main coronary artery (n=2). Attenuation, volume, stenosis and RI were 41.4+/-16.6 HU (range, 20.2 - 69.9 HU), 55+/-55 mm3 (range, 15-179 mm3), 40.7+/-16.3% (range,16.0-68.0%) and 1.35+/-0.13 (range, 1.16-1.50). Lipid rich plaque and significant stenosis were detected in 6 patients and in 2 patients, respectively. CONCLUSION: Despite negative CAC as detected on MDCT, atherosclerotic plaque might have significant stenosis or lipid rich plaque. Therefore, negative CAC does not seem to guarantee the absence of CAD. Coronary CT angiography was recommended for patients with negative CAC.

OBJECTIVE: The purpose of this study was to examine smoking status and the relates factors in the rural elderly. METHODS: This study was conducted with 2,421 elderly people(male 1,273 and female 1,148) residing in the selected 25 villages, and face-to-face interviews with the subjects were made from January 1 through March 30, 2002. RESULTS: The average age of the male subjects was 72.7 and that of the female subjects 72.8. The investigation of smoking states showed that for male subjects, smokers accounted for 49.4%, nonsmokers 26.9%, and abstainers from smoking 23.7% and that for female subjects, smokers accounted for 18.3%, nonsmokers 75.4%, and abstainers from smoking 6.3%. The level of 'low ADL' was significantly higher in abstainers. In men, smoking rate had higher in alone, non-job, queerstreet, 'high ADL'. In women, smoking rate had higher in younger age, queerstreet, unhealthy, 'high ADL'. CONCLUSIONS: The smoking rate of the elderly was relatively high, especially at abstainers. The smoking status of elderly was correlated with age, family type, job, economic status by self-assessment, Self-recognition of health status, ADL level.

A 29-year-old woman in her 8th week of pregnancy was referred to our hospital for swelling in the lower extremities, rapid onset of dyspnea (1 hr) and pre-syncope. Severe right ventricular dysfunction and moderate pulmonary hypertension were detected using 2-dimentional Doppler echocardiography. In addition, left calf vein and proximal thromboses were detected by venous compression ultrasound imaging. After successful thrombolytic treatment, the patient quickly recovered and was discharged from hospital on subcutaneous low-molecular-weight heparin. She delivered a normal, healthy infant at full-term (40 weeks).

Since Inoue et al introduced a specially designed balloon catheter for percutaneous mitral valvuloplasty (PMV) in 1984, the Inoue balloon catheter has been a popular device for the management of mitral stenosis. During the procedure several fatal complications, such as cardiac tamponade, perforation of a cardiac chamber, atrial septal defect, thromboembolism, mitral regurgitation and death have all been reported in the literature. There have also been several international reports regarding deformities of the Inoue balloon, but few reports in Korea. We recently experienced a case of an inflation failure of the distal portion of the Inoue balloon during a percutaneous mitral valvuloplasty in a 34 year old female patient with a tight mitral stenosis. To the best of our knowledge, a similar deformity of an Inoue balloon has never been reported in Korea.

Since the Inoue balloon was first introduced for percutaneous mitral valvuloplasty (PMV) in 1984, this procedure has come into widespread use because of its effectiveness, simplicity, and reduced exposure to X-ray radiation. It's the procedure's complications include cardiac tamponade, atrial septal defect, thromboembolism, ventricular perforation, mitral regurgitation, and rarely balloon rupture. We report a case of Inoue balloon deformity during PMV in 62-year old woman with rheumatic mitral stenosis. Echocardiography revealed severe rheumatic mitral stenosis with a valvular area of 0.95 cm2 (by pressure half-time method), and an Echo score of 10 points. The PMV with Inoue balloon 28 mm was performed. We inflated the balloon to 28 mm in diameter first, and to 29 mm second. A bulging deformity with asymmetrical overinflation of one side of both proximal and distal balloon was recognized. A bulging deformity at the proximal part of Inoue balloon after second inflation. Balloon was not ruptured. Following completion of the procedure, the mitral valve area increased to 1.8 cm2. Moderate mitral regurgitation (grade II) was newly developed. This may be the first case of asymmetrical one side inflation and focal bulging deformity reported in Korea.

BACKGROUND AND OBJECTIVES: The clinical pattern of infective endocarditis is constantly changing. Diagnosis and treatment of infective endocarditis were developed by recent diagnostic strategy (Duke criteria) and introduction of transesophageal echocardiography. The aim of this study was to compare the clinical character-istics of infective endocarditis in Sejong hospital to the previous report and was to investigate risk factor of heart failure, embolism and death. MATERIAL AND METHODS: All episodes hospitalized of infective endocarditis from January of 1990 to October of 1999 in Sejong hospital were reviewed retrospectively. The total cases of infective endocarditis was 80 cases in 78 patients. RESULTS: The male to female ratio was 1:1.05 (39 male, 41 female). The mean age was 42 years. Rheumatic heart disease was the most common predisposing heart disease in 28.8%, followed by prosthetic valve endocarditis. Streptococci were the most commonly isolated micro-organisms in 18 cases (45.0%), followed by staphylococci in 11 cases. Transesophageal echocardiography has a higher sensitivity than transthoracic echocardiography for detection of vegetation, abscess and paravalvular complication in endocarditis. In patients with echocardiographic vegetation and involvement of aortic valve, there was a statistically significant increase in the risk of heart failure. The factor that was associated with a statistically significant increase in the overall risk of embolization was not exist. Ten patients died (12.5%). Risk factor for death was left ventricular dysfunction. The incidence of death was more higher in patients with abscess and non-streptococcal endocarditis. CONCLUSION: Compared to the 1980's report, we observed increased mean age of patients, the decreasing trend of rheumatic heart disease as a predisposing heart disease and the decreasing incidence of streptococci as causative microorganism. Risk factors for congestive heart failure were aortic valve endocarditis and endocarditis with vegetation. Risk factor for death was left ventricular dysfunction.

The scimitar syndrome, a rare complex anomaly, is defined as an anomalous right pulmonary venous drainage, partial or complete, to the inferior versa cava. The shape of the Turkish curved sword (scimitar) huts provided the name of this syndrome. Additional characteristics of this syndrome such as hypoplasia of the right lung and of the right pulmonary arterial tree, anomalous arterial supply of the right lung from the aorta, dextrocardia and bronchial anomalies are common. Recently we experienced a case of scimitar syndrome (adult form) in a 19-year-old woman patient, so we report the case with a brief review of the literature.

BACKGROUND: This study was designed to investigate the correlation between pain and non-pain sensation of the cutaneous nociceptors in healthy adults use 250 Hz and 5 Hz evoking neuroselective sinusoidal current to A delta and C-fiber separately. METHODS: Fifty healthy adult volunteers who have no history of neurological illness were examined. Twenty-five of them were male, and twenty-five were female. Their ages ranged from 20 to 46 years, with a mean equal to 29.5 years old. The thresholds for both current perception and nociceptive perception were measured bilaterally in volar aspect of wrist using a Neurometer CPT/C (Quantitative Sensory Nerve Testing Device). The manual mode for current perception threshold and the staircase method for nociceptive current perception threshold was performed individually. RESULTS: The mean values of the threshold for perception evoked by 250 Hz were 0.30 mA in left and 0.31 mA in right, 0.17 mA in left and 0.14 mA in right at 5 Hz respectively. The mean values of the nociception threshold were 0.52 mA in both site at 250 Hz and from 0.35 mA to 0.32 mA at 5 Hz (Table 1). There were no differences between left and right wrist (Fig. 1). Also a significant positive correlation between current perception and nociception thresholds was found (p<0.05) (Fig. 2, 3). There appeared to be different between genders in perception threshold evoked by 250 Hz and nociception threshold evoked by 5 Hz in left (p<0.05) (Table 2). CONCLUSIONS: There exists a meaningful correlation between both sensations of non-pain and pain perception thresholds obtained from all subjects. The measurement of the current perception threshold is considered to be a unique and valuable resource in evaluation of patient with neurologic condition, as well as in serial evaluation of patient to assess the outcome of therapeutic intervention.
