Coronary artery bypass grafting (CABG) without extracorporeal circulation (ECC) is now an accepted technique of myocardial revascularization in selective cases of coronary arterial occlusive disease. We experienced a case of CABG without ECC in a 20 year old female patient with complete occlusion of the right coronary artery. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. Nitroglycerine and dopamine were given to stabilize the hemodynamics during intra- and post-operative periods. And esmolol was administered with a loading dose of 30 mg over 1 min, followed by a continuous infusion of 50~100 g/kg/min to maintain the heart rate (50~60 beats/min) and systolic blood pressure (60~80 mmHg) during distal anastomosis. The patient was recovered uneventfully and discharged on the 8th postoperative day.

Tracheopathia osteoplastica is a rare, benign pathologic condition chahacterized the occurrence of numerous cartilage and bony nodules within the tissue of mucosa. We report a case of tracheopathia osteoplastica that involved both larynx and trachea. The patient was 73 years old male and had hoarseness. The neck CT showed thickened and irregular wall of the trachea extending to the level of the carina with multiple calcified nodules and plaques of bony density projecting into the lumen.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

The purpose of this study was to compare microleakage and marginal hybrid layer in class V restorations using two one-bottle adhesives and one self-etching adhesive. Class V cavity preparations with occlusal margins in enamel and gingival margins in dentin were prepared on buccal and lingual surfaces of 30 extracted human molar teeth. Prepared teeth were randomly divided into three treatment groups (n=30) and restored with three adhesives and composites: Single Bond/Filtek Z-250 (Group 1), Prime&BondNT/Esthet.X (Group 2), UniFil Bond/UniFil F (Group 3). For microleakage, samples were stored in room temperature water for 24 hours, thermocycled, stained with 2% methylene blue dye, sectioned into halves, scored and analysed using Mann-whitney test and Wilcoxon signed rank sum test. For marginal hybrid layer, samples were sectioned into halves, treated with 10% phosphoric acid for 5 seconds, stored in 5% NaOCL solution for 24 hours, dried and gold coated. Occlusal and gingival margins of each sample were inspected under SEM. The results of this study were as follows; 1. Microleakage at the occlusal margins was not evident in group 1 and group 2, but it showed in group 3 (p<0.05). 2. Microleakage in group 1 and group 3 was significantly lower than in group 2 at gingival margins (p<0.05). 3. Microleakage at gingival margins was greater than at occlusal margins in group 1 and group 2, but microleakage at occlusal margins was greater than at gingival margins in group 3 (p<0.05). 4. In group 1 and group 2, no gaps at occlusal margins showed. But gaps showed in group 3. Occlusal margins were free from a hybrid layer in all groups. 5. The thickness of the marginal hybrid layers was 2.5~5 microm thick in group 5 microm thick in group 2 and 1.5 microm thick in group 3. 6. There was no corelation between microleakage and thickness of marginal hybrid layer. In coclusion, the effect of dentin adhesives on microleakge in class V composite restorations was excellent when one-bottle adhesives were applied on enamel margin, and it was good when a self-etching adhesive was applied on dentinal margin. There was no corelation between microleakage and thickness of marginal hybrid layer.

Disseminated Fusarium infection has rarely been encountered in neutropenic cancer patients. The clinical features include fever, positive blood cultures, severe myalgias, disseminated ecthyma gangrenosum-like skin lesions, ocular symptoms and multi-organ-system involvement. The mortality rate reported so far exceeded 70% despite antifungal treatments. We report here the first two cases of disseminated fusarial infections in Korea. The first patient contracted pneumonia during severe neutropenic period following consolidation chemotherapy for acute myelogenous leukemia(AML). Fusarium oxyshrum was cultured from bronchoalveolar lavage fluid. The patient remains free of fungemia after successful antifungal treatment of high-dose amphotericin B and terbinafine. The second patient had relapsed AML and suffered from disseminated fusarial infection involving lungs with characteristic skin lesions. The patient succumbed to refractory leukemia and the fungal infection. A brief review of the literature ensues with the case report.

The extraaxial presentation of medulloblastoma is a rare phenomenon. This article describes the case of 19-year old woman who presented with mild headache and nausea and was diagnosed with medulloblastoma. The tumor arose from the right cerebellar cortex, and it was misdiagnosed meningioma on the basis of radiological examination. We review the literature and discuss the such atypical presentation of medulloblastoma.

The purpose of this study was to compare the effect of exponential curing method with conventional curing and soft start curing method on polymerization shrinkage of composite resins. Three brands of composite resins (Synergy Duo Shade, Z250, Filtek Supreme) and three brands of light curing units (Spectrum 800, Elipar Highlight, Elipar Trilight) were used. 40 seconds curing time was given. The shrinkage was measured using linometer for 90 seconds. The effect of time on polymerization shrinkage was analysed by one-way ANOVA and the effect of curing modes and materials on polymerization shrinkage at the time of 90s were analysed by two-way ANOVA. The shrinkage ratios at the time of 20s to 90s were taken and analysed the same way. The results were as follows: 1. All the groups except Supreme shrank almost within 20s. Supreme cured by soft start and exponential curing had no further shrinkage after 30s (p < 0.05). 2. Statistical analysis revealed that polymerization shrinkage varied among materials (p = 0.000) and curing modes (p = 0.003). There was no significant interaction between material and curing mode. 3. The groups cured by exponential curing showed the statistically lower polymerization shrinkage at 90s than the groups cured by conventional curing and soft start curing (p < 0.05). 4. The initial shrinkage ratios of soft start and exponential curing were statistically lower than conventional curing (p < 0.05). From this study, the use of low initial light intensities may reduce the polymerization rate and, as a result, reduce the stress of polymerization shrinkage.
