1.Pathophysiologic Mechanism of the Cardiac Failure in the Subacute Diffuse Myocarditis associated with Granulomatous Myocarditis.
Korean Journal of Legal Medicine 1997;21(1):87-96
The heart, 500g in weight, with subacute myocarditis associated with granulomatous myocarditis may be a good model for the study on the pathophysiologic mechanism of cardiac failure. Furthermore, the clinical data of this case is enough to clarify his all clinical course from admission to death due to cardiac failure. So, we analyzed the clinical data, histologic findings, and morphometric pattern of histologically intact myocardial cells and inflammatory reaction to investigate the pathophysiologic mechanism of the cardiac failure. The results were summarized as follows. 1. Clinically, the heart showed cardiac failure of diastolic phase and abnormal conduction system related to sudden cardiac death. However, it might be adapted to the relatively stable wital signs due to pericardial positive pressure by slowlyprogressed pericardial effusion. 2. The distribution pattern of area of intact myocardial cell area and inflammtion reaction showed relatively even spread of inflammatory reaction and extremely decreased area of myocardial cells to about 21% of total heart. So, its contractility might be decreased below to the 21% of the normal cardiac contractility. 3. The mechanism of the cardiac failure in myocarditis may be sudden inflammatory involvement of conduction system and/or extremely decreased myocardial cell volume due to inflammatory destruction. 4. Morphometric analysis may be a useful objective method to grading the severity of old and recent form of myocarditis. From the above results, the cardiac failure of myocarditis is influenced by the adaptability at the inflammatory abnormality of the conduction system, contractility of injured myocardial cells, and compensation activity of pericardial effusion.

Coronary artery calcification(CAC) is found frequently in the atheromatous plaques CAC is known to have increased frequency above 40 years. CAC without evidence of atherosclerosis in young adults is quite rare, however, CAC combined with aneurysms in young adults have been infrequently reported in patients with a past history of a Kawasaki disease in child. We report an autopsy case showing CAC and aneurysm in the absence of macroscopically identified atherosclerotic lesions in a healthy 23-year-old man. The autopsy examination revealed aneurysmal dilatation of the right coronary artery which was connected with calcified lesion. A calcified lesion of the left anterior descending coronary artery was aslo noted. Microscopically, aneurysmal wall was non-specific except for hyalinized wall and foci of calcification. A striking histologic finding of calcified mass was ring calcification along the wall of the coronary artery. Antecedent Kawasaki disease in the past was suggestive as other reports.

Korean Journal of Legal Medicine 1997;21(1):97-104
Aortic dissection may be considered the result of a discrepancy between the strength of the aortic wall and the intramural pressure. And factors that predispose to aortic dissection may include systemic hypertension, cystic medial necrosis, Marfan's syndrome, atherosclerosis, disease of aortic valve, pregnancy, giant cell arteritis, hyperthyrosis, disease of aortic valve, pregnancy, giant cell arteritis, hyperthyroidism, and blunt chest trauma. A few of aortic dissection may extend retrograde toward the aortic valve and involve the coronary arteries. Coronary artery occlusions due to mural dissection are an uncommon but well documented cause of myocardial infarction. Although rare, extramural hematoma compressing the coronary artery is another cause of myocardial infarction. At autopsy of 43 years old male who had no critical external wound, pericardial sac was distended and contained 400ml of dark red and clotted blood. Examination of the aorta revealed only minute atherosclerosis, intact aortic valve, and patent coronary ostia. 0.5cm sized aortic rupture was noted at the 3.5cm distal to the aortic valve. DeBakey type II aortic dissection was found to involve the ascending aorta and brachiocephalic trunk. Three intimal tears were 1.5cm, 8cm. 11.5cm distal to the aortic valve and two false lumens which had intact area between them extended 3.5cm distal to the third intimal tear and proximally in a retrograde fashion to the aortic root. Microscopically, sections of aorta showed relatively intact arrangement of smooth muscle and elastic fibers, except mild vascular ectasia and scattered several foci of the small sized aggregation of foamy histiocytes, and there was no evidence of cystic medial degeneration in aorta. Sections of both coronary arteries did not show mural dissection or atherosclerosis. Sections of right atrium and sinus node showed inflammatory reaction, extensive replacement of myocardium by active fibrous tissue consistent with infarction. There was no histologic evidence of myocardial infarction in the walls of other chambers or septum of the heart. We believe that extramural compression of the artery to sinus m\node by the dissecting hematoma was the cause of myocardial infarction involving the right atrium and the sinus node.

Hypertrophic cardiomyopathy (HCMP) is characterized myofiber hypertrophy and structural remodeling with changes in the proportion of the muscular, vascular, and interstitial compartments. A study was done to determine the structural remodeling patterns and the role of microvasculature of hearts in HCMP. Forty-two postmortem hearts were analyzed including 14 from patients who died of HCMP (group 1), 8 patients with HCMP but who died from extracardiac causes (group 2), 10 patients with ischemic heart disease (group 3), and 10 normal adult hearts (group 4). Macro- and microscopic examination, immunohistochemical study using CD34 antibody, and morphometric studies using image analyzer were performed. Mean cardiac weight and wall thickness were significantly higher in the HCMP group. Myocardial hypertrophy, and a variety of myocardial disarray and fibrosis involved the whole area of the left ventricles with HCMP. The percentage areas of microvessels were 6.40 0.7 in group 1, 5.90 0.6 in group 2, 4.98 0.3 in group 3, 4.85 0.4 in group 4, respectively, and the numbers of microvessels were 198.0 20.7 in group 1, 230.0 22.3 in group 2, 211.7 11.2 in group 3, and 236.4 11.4 in group 4, respectively (mean SE). The percentage area of microvessels was significantly higher in group 1 than in other groups. However, the number of microvessels in that group was lower than in the other groups, although it was statistically insignificant. Since flow-dependent vasodilation is preserved in HCMP, we considered flow-dependent vasodilation the cause of the discrepancy between the area and the number of microvessels. Ischemic changes observed in chronic HCMP and related heart failure were considesed to be due to the relative deficiency of the coronary flow compared to the increasing cardiac mass.

5.Nontraumatic Injuries of Lung.
Korean Journal of Legal Medicine 1997;21(2):76-83
Injury is generally defined as morphological changes due to physical or chemical stress, inflammatory or repair process, or secondary events of the other disease. In the nontraumatic injuries of the lung, direct physical effects to the lung such as contusion or rupture of the lung must be excluded. So, the types of nontraumatic injuries of lung are all pathologic changes of lung except for congenital anomalies; infectious of inflammatory disease, aspiration induced injuries, environmental or occupational lung disease, postoperative pulmonary changes, poison or drug induced toxic injuries, radiation injury, etc...

6.Analysis of the Significance in the Forensic Application of the STR CSF1PO, STR TPOX, STR TH01 Loci.
Korean Journal of Legal Medicine 1998;22(1):40-49
Alleles and genotype frequencies and its distribution pattern for three STR loci; CSF1PO, TPOX, and TH01 were analyzed for the evaluation of the useful-ness of STR loci in the individual identification. STR CSF1PO locus showed 7 allele types and 18 genotypes. However, 3 of 7 allele types are related to 84.3% of population and 4 of 18 genotypes are related to 67.6% of population. Heterozygosity is 70.6%. STR TPOX locus showed 5 allele types and 12 genotypes. However, 2 of 5 llele types are related to 81.92% of population and 3 of 12 genotypes are related to 78.4% of population. Heterozygosity is 65.7%. STR TP01 locus showed 5 allele types and 13 genotypes. However, 2 of 5 llele types are related to 78.9% of population and 3 of 13 genotypes are re-lated to 71.6% of population. Heterozygosity is 68.6%. From the above results, CSF1PO, TPOX, and TH01 loci have small numbers of allele types and genotypes. Many population is included into the specific allele types and genotypes. So, statistical analysis of allele and genotype frequency may have risks of misinterpretation of negative results to positive results. To remove the statistical errors, more than three STR loci have to be used in individual identification and the distribution pattern of the frequency of allele types and genotypes have to be analyzed in the STR loci.

Among 334 thoracolumbar spinal injury patients who were admitted to this hospital from June 1972 to June, 1982, 66 patients with fracture and fracture dislocation of thoraco-lumbar spine which were defined as unstable clinically and radiologically were treated with surgical measures. The ratio between male and female was 7.3:1, the majority was found in third and fourth decade (46 cases, 69%), and the most common cause of injury was falling from a height (38 cases, 58%). The most common site of the injury was lumbar spine (29 cases, 44%) and the most common mechanism of injury was flexion-rotation (29 cases, 44%). Our surgical measures were Harrington rod instrumentation with either anterior or posterior fusion (25 cases, 38%), posterior wiring and fusion (14 cases, 21%), anterior decompression and anterior fusion (14 cases, 21%), posterior fusion (4 cases, 6%), anterior fusion and posterior fusion (3 cases, 5%) and etc. The average correction of displacement was 65% and the average correction of kyphotic deformity was 50%. The most remarkable correction was found at the cases of Harrington rod instrumentation (71%, 74%). Neurological deficit had already developed in 43 cases(65%) prior to operation, and the recovery was observed in 18 cases(42%). Most excellent recovery of neural deficit was found also at the cases of Harrington rod instrumentation (11 cases, 52%). We have analysed the results of these treatment and obtained following conclusions. 1. For the unstable fracture and fracture-dislocation of thoraco-lumbar spine with or without neural involvement, immediate surgical treatments were valuable to expect restoration of anatomical reduction and promotion of every possible recovery of neural function with spinal stability and fewest complication. 2. Fixation with Harrington rod instrumentation appears to provide better reduction and stability with neural improvement than other methods, and therefore early undertaking of rehabilitation activities is possible. 3. For the patients who are seriously compromised or require anterior decompression, immediate posterior reduction and fixation with Harrington rod instrumentation followed anterior decompression and anterior fusion of the involved segments at the eariest feasible time, we feel, is the treatment of choice.

There was increasing tendency to stabilize unstable cervical spine injuries surgically with the benefit of good stability of the spine, easy nursing care, early mobilization and therefore early rehabilitation. A clinical study was performed on 47 patients with fractures and dislocations of the cervical spine treated at the department of orthopedic surgery, Inje Medical College, Paik Hospital from Jan. 1975 to Dec. 1981. Following is the summery of the our findings. 1. The prevalent age distribution was between 3rd and 6th decade and the ratio between males and females was 10:1. The most common cause of injuries was automobile accident (70%). 2. The most common site of the injuries was C5-6 (34%) and the most frequent mechanism of injury was flexion-rotation type (47%). 3. In overall patients, neurologic damage was found at first examination in 73% and among these, complete paralysis below the injured level in 26%, incomplete paralysis in 11% and nerve root injury in 35%. 4. Among 47 patients, conervative treatment was performed on 9 patients, anterior spinal fusion on 8 patients, anterior spinal fusion with Halo application on 4 patients, posterior wiring with posterior spinal fusion on 16 patients and posterior wiring with anterior spinal fusion on 8 patients. 5. In the several methods of treatment, the posterior wiring with anterior spinal fusion revealed the best results, the correction rate of displacement was 92%, the correction rate of angular deformity 98% and neural recovery rate 72%. 6. The posterior wiring with posterior spinal fusion revealed good results in correction of displacement and angular deformity but required rigid external support for a long time. The anterior spinal fusion revealed poor results in correction of displacement(67%) and angular deformity(38%) and required rigid external support for a long time and had increasing tendency of kyphotic angle after operation. 7. In the treatment of unstable cervical spine injury, we thoughy that early posterior reduction with posterior wiring and followed anterior spinal fusion was ideal for accurate reduction, rigid stability and early mobilization with simple external support.

Atlanto-axial instability is an important condition that may threaten the integrity of spinal cord, leading to tetraplegia or sudden death. Many of these require operative stability, and several different operations have been advocated. Among these methods, Brooks and Jenkins posterior fusion for eleven cases of atlanto-axial instability (fresh fracture of odontoid process in nine, nonunion of odentoid fracture in one, Cl-2 rotary subluxation in one) was performed in Baik Hospital from July 1978 to June 1987, and the following results were obtained. l. Accurate reduction and immediate rigid stability were obtained with Brooks and Jenkins posterior fusion, so early ambulation with simple external support was begun within 2 weeks after operation. 2. Radiological fusion of atlanto-axial instability were seen in average 12 weeks after operation. Therefore posterior atlanto-axial fusion by Brooks and Jenkins method is an excellent method for operative treatment of atlanto-axial instability.

42 knees with degenerative arthritis underwent arthroscopic lavage and 7 knees underwent arthroscopic lavage combined with multiple bone drilling in between 1994 and 1995 and followed average 12 months. Clinical evaluation using the hospita1 for specia] surgery knee scores (HSS scores) was done at last follow up and classified into 4 groups: excellent (90-99), good (80-89), fair (70-79) and poor (less than 70). The results were as follows: l. Of the 42 knees of the lavage group, 6 knees (16%) was excellent, 14 knees (33%) good, ]7 knees (40%) fair and 5 (11%) knees poor. Success group (Excellent & Good) were achived in 20 knees (49%). 2. Of 17 knees treated with arthroscopic lavage comhined with multiple bone drillig resulted in excellent in 9 knees (53%), good in 4 knees (23%), fair in 2 knees (12%) and poor in 2 knees (12%). Success group were achived in 13 knees (76%). 1n conclusion, we helieve that multiple bone drilling in conjunction with arthroscopic lavage has more favorable effect on the pain relief for degenerative osteoarthritis of the knee than arthroscopic lavage only.
