In order to observe the arrhythmia which occured in early convalescent phase of acute myocardial infarction, a 24 hour ambulartory ECG monitiring was performed in 15 patients who is admitted at dept of Int Medicine, Ewha Womans University hospital from Aug. 1985 to Sept. 1986. during 7.5+/-3.4 days after admission. In all cases one or more of the following arrhythmias were observed;atrial premature beat, ventricular premature beat(VPB), transient paroxysmal ventricular thchycardia, atrial fibrillation, sinus arrest and junctional beat. Of 15 cases, 11(77.3%) had VPB's:Simple VPB's in 4 cases(26.7%) and complex VPB's(6.52+/-2.52)(P<0.05). But there were no difference of premature and abberancy index between complex VPB's and simple VPB's(P>0.1). In addition, we compaired the arrhythmias in CCU with those of early convalescent phase of acute myocardial infarction. But there was no correlation between them.

5.Cancer Vaccines Targeting HER2/neu for Early Breast Cancer.
Journal of Breast Cancer 2010;13(1):5-13
Recent studies of immune responses to pathogens have identified pathogen-associated molecular patterns recognized by the innate immune system through specialized receptors called toll-like receptors (TLRs). Signaling through these receptors initiates robust immune responses. By exploiting TLR signaling pathways, immunity to tumor-associated antigens may be generated. Many tumor-associated antigens are involved in the regulation of tumor phenotype or carcinogenesis. Immune targeting of these antigens may either alter the tumor phenotype, yielding a more treatable tumor, or eradicate early tumor stem cells preventing tumor formation. The oncoprotein HER2/neu, which is often overexpressed in ductal carcinoma in situ (DCIS), may provide such a target. Immune responses directed against HER2/neu may eliminate the disease, make tumors more amenable to anti-estrogen therapy, or prevent escape of hormone-resistant tumor phenotypes. Effective breast cancer prevention in preclinical studies utilizing murine HER2/neu transgenic models has stimulated interest in, and optimism regarding, protective breast cancer vaccines in humans. Induction of anti-HER2 neu T cell (CD4+ and CD8+) and B cell responses has been demonstrated in an ongoing clinical study targeting HER2/neu using a TLR agonist-primed dendritic cell vaccine. Moreover, these vaccinations lead to reductions in both HER2/neu expression and extent of DCIS. HER2/neu expression and aromatase activity have recently been linked through the intermediary cyclooxygenase 2 (COX-2). This convergence between growth factor and hormone mediated pathways provides additional support for the notion that a significant number of breast cancers may be prevented through effective immune targeting of HER2/neu. As progress is made towards the development of vaccines for breast cancer prevention, the contributions of immune-mediated effecter and inhibitory mechanisms to the pathogenesis of HER2/neu overexpressing breast cancer will need to be better understood.

6.The Various Reconstruction with Hydroxyapatite Powder(Bonesource(R)).
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2004;31(5):649-654
Necessity of more biocompatible bone graft material had brought due to the problems of autologous bone graft & synthetic bone substitute materials. Bonesource(R) is a new biomaterial which can be replaced by natural bone when it is implanted. We reviewed our experience with Bonesource(in various reconstruction of bone defect for wide application. From March 2000 to March 2002 at Seoul National University Hospital, we performed various 7 cases of operation with Bonesource(R). These cases were bony depression after mass excision, alveolar cleft, frontal and supraorbital rim fracture, orbital deformity, facial asymmetry, bone defect after cranioplasty, depressive scar. In all cases, results were satisfactory without migration, extrusion, resorption during the follow up period (average 14 months). In 1 case, wound healing was delayed due to redissolution of Bonesource(R) by seroma. This was resolved by drainage without significant loss of volume. Its biocompatibility, excellent bony adhesion(osseointegration) and tendency to be replaced by natural bone(osteoconduction) may make it widely used in plastic surgery. The result of long term follow up and practical technique handling this material effectively are needed to evaluate it further.

OBJECTIVE: Anterior cervical corpectomy with fusion (ACF) or laminoplasty may be associated with substantial number of complications for treating multilevel cervical ossification of the posterior longitudinal ligament (OPLL) with significant cord compression. For more safe decompression and stabilization in multilevel cervical OPLL with prominent cord compression, we propose circumferential cervical surgery (selective ACF and laminoplasty) based on our favorable experience. METHODS: Twelve patients with cervical myelopathy underwent circumferential cervical surgery and all patients showed multilevel OPLL with signal change of the spinal cord on magnetic resonance imaging (MRI). A retrospective review of clinical, radiological, and surgical data was conducted. RESULTS: There were 9 men and 3 women with mean age of 56.7 years and a mean follow up period of 15.6 months. The average corpectomy level was 1.16 and laminoplasty level was 4.58. The average Japanese Orthopedic Association score for recovery was 5.1 points and good clinical results were obtained in 11 patients (92%) (p < 0.05). The average space available for the cord improved from 58.2% to 87.9% and the average Cobb's angle changed from 7.63 to 12.27 at 6 months after operation without failure of fusion (p < 0.05). Average operation time was 8.36 hours, with an estimated blood loss of 760 mL and duration of bed rest of 2.0 days. There were no incidences of significant surgical complications, including wound infection. CONCLUSION: Although the current study examined a small sample with relatively short-term follow-up periods, our study results demonstrate that circumferential cervical surgery is considered favorable for safety and effectiveness in multilevel OPLL with prominent cord compression.

OBJECTIVE: The purpose of this study is to examine radiological adjacent segment degeneration (ASD) and clinical results after two levels percutaneous pedicle screw fixation. METHODS: From 2007 to 2009, 34 patients who underwent percutaneous pedicle screw fixation on L3-4-5 or L4-5-S1 for lumbar degenerative disorders were selected. According to the presence of radiological ASD, ASD group and non-ASD group were compared for clinical results and radiologic results such as total lordotic angle (TLA), segmental lordotic angle (SLA) via lumbar X-rays during follow up periods. Furthermore, we compared pre-operative degree of disc degeneration at adjacent segment between two groups via MRI. RESULTS: The mean follow-up period and mean age were 27.38+/-9.45 months and 59.21+/-12.73 years. ASD group were 7 patients, and non-ASD group were 27 patients. The mean age of the ASD group (67.40+/-4.81) was significantly older than that of the non-ASD group (57.46+/-13.18). Pre-operative disc degeneration of cranial adjacent segment in ASD group were 6 patients (25.9%), whereas that in non-ASD group were 4 patients (14.8%), showing that preoperative disc degeneration was significantly more severe in the ASD group. CONCLUSION: Percutaneous pedicle screw fixation is favorable technique to prevent ASD for two levels fusion, however, when the patient is old or the preoperative disc degeneration of the adjacent segment is severe, there is the risk of postoperative ASD, and thus special attention should be paid during the follow-up period.

Journal of Korean Neurosurgical Society 2013;53(2):83-88
OBJECTIVE: The authors reviewed their experiences of combined surgery (open door laminoplasty with unilateral screw fixation) for unstable multi-level cervical stenosis, to clarify the situation regarding the surgical approach most appropriate for the treatment of diffuse unstable multi-level cervical stenosis. METHODS: From January 2011 to January 2012, combined surgery was performed for unstable multi-level cervical stenosis by one surgeon at our institution. The subjects of this study were 6 men of mean age 53.7 years (range, 48-71) with a mean follow-up of 9.3 (range, 3-14) months. All imaging studies showed severe multi-level cervical stenosis with spinal cord signal change, and instability or kyphotic deformity. A retrospective review of clinical, radiological, and surgical data was conducted. RESULTS: Average laminoplasty level was 4.8 and the average screw fixation level was 5.0. Japanese Orthopedic Association score improved from an average of 5.2 to 11.2 points. According to Nurick's grades and Odom's criteria, symptom improvement was statistically significant. On the other hand, Cobb's angle changes were not significant. Average operation time was 5.86 hours with an average blood loss of 460 mL. No significant surgical complication was encountered. CONCLUSION: Despite the small cohort and the short follow-up duration, the present study demonstrates that laminoplasty with unilateral screw fixation is a safe and effective treatment for unstable multi-level cervical stenosis.

Journal of Korean Neurosurgical Society 2014;56(3):211-217
OBJECTIVE: In Korea, early vertebroplasty (EVP) or delayed vertebroplasty (DVP, which is performed at least 2 weeks after diagnosis) were performed for the treatment of acute osteoporotic compression fracture (OCF) of the spine. The present study compared the outcomes of two surgical strategies for the treatment of single-level acute OCF in the thoracolumbar junction (T12-L2). METHODS: From 2004 to 2010, 23 patients were allocated to the EVP group (EVPG) and 27 patients to the DVP group (DVPG). Overall mean age was 68.3+/-7.9 and minimum follow-up period was 1.0 year. Retrospective study of clinical and radiological results was conducted. RESULTS: No significant differences in baseline characteristics were observed between the two groups. As expected, mean duration from onset to vertebroplasty and mean duration of hospital stay were significantly longer in the DVPG (17.1+/-2.1 and 17.5+/-4.2) than in the EVPG (3.8+/-3.3 and 10.8+/-5.1, p=0.001). Final clinical outcome including visual analogue scale (VAS), Oswestry Disability Index, and Odom's criteria did not differ between the two groups. However, immediate improvement of the VAS after vertebroplasty was greater in the EVPG (5.1+/-1.3) than in the DVPG (4.0+/-1.0, p=0.002). The proportion of cement leakage was lower in the EVPG (30.4%) than in the DVPG (59.3%, p=0.039). In addition, semiquantitative grade of cement interdigitation was significantly more favorable in the EVPG than in the DVPG (p=0.003). Final vertebral body collapse and segmental kyphosis did not differ significantly between the two groups. CONCLUSION: Our findings suggest that EVP achieves a better immediate surgical effect with more favorable cost-effectiveness.
