Dynamic cardiomyoplasty is a recently introduced surgical method to improve myocardial performance. It consists of a placement of a skeletal muscle flap around the heart and stimulation of the flap in synchrony with ventricular contraction. We experienced a case of cardiomyoplasty in a 25 year old male patient with congestive heart failure. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. The operation was performed for 8hrs without cardiopulmonary bypass and the patient was transferred to the intensive care unit. He was mechanically ventilated electively overnight and extubation was done 18hrs postoperatively. The patient was discharged home on the 40days after operation and improved in exercise tolerance. We report the anesthetic management and hemodynamic changes in a patient who underwent dynamic cardiomyoplasty.

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.

Jehovah,s Witnesses who require operation represent a challenge to the physician because of the patient,s refusal to accept blood transfusion. An orthotopic heart transplantation was succesfully performed in a 40-year old Jehovah,s Witness without use of any blood product. During the operation, cell saver was used for shed blood and aprotinin was administered intravenously. The use of blood conserving methods, meticulous operative technique and brisk postoperative diuresis has added to the efficacy of heart transplantation in this patient. Total postoperative drainage was 860 ml and the lowest hemoglobin level was 11.8 g%. The patient recovered uneventfully and discharged on the 60th postoperative day.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

Objective:
Recently, the lipid profile of atherogenic dyslipidemia has become important in cerebrovascular diseases. Atherogenic index of plasma (AIP), an index that reflects this lipid profile as a single number, has been proposed, but there are still few related studies in cerebrovascular disease. In this study, we evaluated the relationship between AIP and cerebral small vessel disease (cSVD) in health check-up participants.
Methods:
We assessed consecutive health check-ups participants between 2006 and 2013. cSVD was measured including the following three subtypes: white matter hyperintensity (WMH), lacuens, and cerebral microbleeds (CMBs). WMH quantitatively measured the volume, and lacunes and CMBs qualitatively evaluated the presence. AIP was calculated according to the following formula based on blood test results: AIP=log [triglyceride (mg/ dL)/high-density lipoprotein cholesterol (mg/dL)].
Results:
A total of 3,170 participants were evaluated (mean age: 56.5 years, male sex: 53.8%). In multivariable linear regression analysis, AIP (β=0.129, 95% confidence interval [CI]=0.003–0.255) was associated with WMH. Age, hypertension, diabetes, lipid-lowering agents, and intracranial atherosclerosis were also associated with WMH volume. In multivariable logistic regression analysis, AIP (adjusted odds ratio=1.72 1.79, 95% CI=1.03– 2.90) showed close association with lacunes. Age and intracranial atherosclerosis were also related to lacunes. CMBs did not show a statistically significant association with AIP.
Conclusion
High AIP was associated with cSVD in health check-up participants. Since this close relationship was only seen in WMH and lacunes, these subtypes may have arisen from a more atherosclerosis-related pathology.

PURPOSE: Optic disc harmatoma is usually seen in tuberous sclerosis patients, but, it may be seen in otherwise normal people. Visual acuity is usually not affected by this lesion. METHODS: We experienced a 40-year-old woman with optic disc hamartoma who presented with acute visual defect. With oral triamcinolone 48mg/day, her visions recovered to normal in 2 weeks. RESULTS: Her age, symptom, and course of disease supported the diagnosis of optic neuritis. CONCLUSION: We report this patient as a case of optic disc hamartoma combined with optic neuritis.

Platelet-rich plasma (PRP) has been known to increase the rate and degree of bone formation by virtue of growth factors in concentrated platelets. Although its great healing effect on bone defect or pre-implantation site preparation in conjunction with bone substitute has been reported, the effect associated with implant is unknown. The purpose of this study was to investigate the effect of PRP on rapid osseointegration of endosseous dental implants in the rabbit tibiae. Twenty two adult female New Zealand white rabbits, weighing approximately 2.7-3.3kg, were used for this study. Twelve of the 22 animals were used for histomorphometric analysis and ten of the 22 were for removal torque test. Each animal received two implants in each tibia (two treated with PRP and two as control) and was given fluorochrome intramuscularly. For histomorphometric analysis, rabbits were divided into four groups according to the healing period. At 1 week, 2 weeks, 4 weeks and 8 weeks postoperatively, each three animals were sacrificed serially and the amount and rate of bone formation around dental implant were examined on the undecalcified sections under fluorescent microscope, polarized microscope and light microscope connected to a personal computer equipped with image analysis system. For removal torque test, rabbits were divided into two groups and removal torque tests were performed at 4 weeks, 10 weeks after implant placement. In total, 88 screw shaped, commercially pure titanium implants (Neoplant, Neobiotech, Seoul, Korea) were used in this study. Labeling pattern reflected differences of two groups in bone formation rate at each period. Histomorphometrically, PRP group showed significantly higher bone volume within threads compared to control group at 2 weeks (70.30+/-4.96% vs. 50.68+/-6.33%; P<.01) and 4 weeks (82.59+/-5.94% vs. 72.94+/-4.57%; P<.05). PRP group at 1, 2 and 4 weeks revealed similar degree of bone volume formation comparable to control group at 2, 4 and 8 weeks, respectively. On the other hand, while PRP group showed higher bone-implant contact (47.37+/-8.09%) than control group (33.16+/-13.47%) at 2 weeks, there were no significant differences between PRP group and control group for any experimental period. Removal torque values also showed no significant differences between PRP group and control group at any experimental period (P>.05). These findings imply that PRP could induce rapid, more bone formation around implant during early healing period and get faster secondary stability for reducing healing period, though it has not induced bone maturation enough to resist functional loading.
