Hepatic changes in eight cases of systemic lupus erythematosus(SLE), were studied to evaluate the nature of hepatic injury of SLE and its relation to lupoid hepatitis. Common histologic changes of the liver in SLE included intralobular necro-inflammatory activities, fatty change, canalicular bile stasis and mild perivenular and Disse space fibrosis. The fatty change and intralobular fibrosis were thought not to be due to SLE itself but associated with steroid administration or chronic alcoholic consumption. The necro-inflammatory changes were usually mild and features of chronic active hepatitis with periportal destruction occured in one case. Symptoms related to the involvement of many other organs than the liver appeared much frequently in patients with SLE than lupoid hepatitis, suggesting that the SLE involving liver and the lupoid hepatitis are different diseases.

Dermatomyositis is a disease of unknown etiology characterized by inflammation and degeneration of skeletal muscles and cutaneous abnormalities. Cardiac involvement in dermatomyositis-polymyositis is thought to be rare. In recent year, however, there has been an increasing number of reports on cardiac abnormalities in adult dermatomyositis and polymyositis due to development of noninvasive diagnostic techniques. Categorically, these abnormalities have included electrocardiographic changes, cardiac arrhythmias, congestive heart failure, coronary artery disease, and pericarditis. A 56-year-old woman was admittied to the Ewha womans University Hospital with dyspnea and palpitation. She was diagnosed as having dermatomyositis and followed up our department of Dermatology. Electrocardiogram showed a paroxysmal supraventricular tachycardia at as rate of 195/min. The patient was treated with 240mg/day verapamil p.o, 60mg/day prednisone p.o, there was marked improvement of symptoms. Systematic study of cardiac function utilizing echocardiography, Holter monitoring, thallium-201-scan, and gated blood pool studies were conducted in five newly diagnosed patients with dematomyositis-polymyositis. A significant elevation of serum CPK-MB is indicative of cardiac involvement. Cardiac involvement is a serious prognostic sign. We report a case with the review of the literature.

BACKGROUND: Congenital aortic stenosis in children is characterized by "excessive" left ventricular hypertrophy with reduced left ventricular systolic wall stress that allows for supernormal ejection performance. We hypothesized that left ventricular wall stress was decreased immediately after surgical correction of pure congenital aortic stenosis. Also measuring postoperative left ventricular wall stress was a useful noninvasive measurement that allowed direct assessment for oxygen consumption of myocardium than measuring the peak systolic pressure gradient between ascending aorta and left ventricle for the assessment of surgical results. MATERIAL AND METHOD: Between September 1993 and August 1999, 8 patients with isolated congenital aortic stenosis who underwent surgical correction at Yonsei cardiovascular center were evaluated. There were 6 male and 2 female patients ranging in age from 2 to 11 years(mean age, 10 years). Combined Hemodynamic-Ultrasonic method was used for studying left ventricular wall stress. We compared the wall stress peak systolic pressure gradient and ejection fraction preoperatively and postoperatively. RESULT: After surgical correction peak aortic gradient fell from 58.4+/-17.6, to 23.7+/-17.7 mmHg(p=0.018) and left ventricular ejection fraction decreased but it is not statistically significant. In the consideration of some factors that influence left ventricular end-systolic wall stress excluding one patient who underwent reoperation for restenosis of left ventricular outflow tract left ventricular end-systolic pressure and left ventricular end-systolic dimension were fell from 170.6+/-24.3 to 143.7+/-27.1 mmHg and from 1.78+/-0.4 to 1.76+/-0.4 cm respectively and left ventricular posterior wall thickness was increased from 1.10+/-0.2, to 1.27+/-0.3cm but it was not statistically singificant whereas left ventricular end-systolic wall stress fell from 79.2+/-24.9 to 57.1+/-27.6 kdynes/cm2(p=0.018) in 7 patients. For one patient who underwent reoperation peak aortic gradient fell from 83.0 to 59.7 mmHg whereas left ventricular end-systolic wall stress increased from 67.2 to 97.0 kdynes/cm2 The intervals did not change significnatly. CONCLUSION: We believe that probably some factors that are related to left ventricular geometry influenced the decreased left ventricular wall stress immediately after surgical correction of isolated congenital aortic stenosis. Left ventricular wall stress is a noninvasive measurement and can allow for more direct assesment than measuring peak aortic gradient particularly in consideration of the stress and oxygen consumption of the myocardium therefore we can conclude it is a useful measurement for postoperative assessment of congenital aortic stenosis.

Background: Bone grafts can provide an optimal environment for permanent tooth to erupt and enhance the stability of the alveolar maxilla. Although autologous bone is an optimal source for osteogenesis, its inevitable donor site morbidity has led to active research on bone substitutes. This study was designed to evaluate the safety and feasibility of using biphasic calcium phosphate (BCP; Osteon) as a bone substitute in dogs. Methods: Bilateral third and fourth premolars of four 15-week-old mongrel dogs were used. All teeth were extracted except the third premolar of the right mandible, which was used as a control. After extraction of the premolars, each dog was administered BCP (Osteon), demineralized bone matrix (DBM; DBX), and no graft in the hollow sockets of the right fourth premolar, left fourth premolar, and left third premolar, respectively. Radiographs were taken at 2-week intervals to check for tooth eruption. After 8 weeks, each dog was sacrificed, and tooth and bone biopsies were performed to check for the presence of tooth and bone substitute particle remnants. Results: Four weeks after the operation, permanent tooth eruptions had started at all the extraction sites in each dog. Eight weeks after the operation, all teeth had normally erupted, and histological examination revealed BCP particles at the right fourth premolar. Conclusion: In all four dogs, no delay in the eruption of the teeth or shape disfigurement of permanent teeth was observed on gross inspection and radiologic evaluation. On histological examination, most of the BCP and DBM were replaced by new bone. Bone substitutes can be used as graft materials in patients with alveolar clefts.

We clinically reviewed four patients who were suffering from aseptic meningitis combined with polio-like paralysis and performed radiological. neurological and virological studies on them. Three patients were admitted to the department of Pediatrics. Asan Medical Center from March to August 1990, and one patient was admitted to the department of Pediatrics. Kangnam General Hospital. The results were as follows; 1) During the period of study, 18 patients (10.1%)out of 178 aseptic meningitis patients also suffered from hand, foot and mouth disease, and three patients (1.69%) out of 178 patients also suffered from polio-like paralysis. 2) The age of the patients who also suffered from polio-like paralysis were eight months, 22 months, 23 months and four years old respectively. Three patients were male and one patient was female. 3) Paralysis developed three to five days after aseptic meningitis infection. 4) In two cases, Magnetic Resonance Imaging (MR) showed two small cavitary lesions that means anterior horn cell necrosis in concordant with residual paralysis. Axial T1-weighted image showed decreased signal intensity and axial T2-weighted image showed increased signal intensity. In another case 20 days after onset of illness MR was performed, the transverse myelitis showed mild swelling of cornus medullaris. Follow up MR in 2 months revealed atropic change in lower thoracic spinal cord. 5) The electromyography and nerve conduction velocity test revealed acute polyradiculoneuropathy. 6) Serologic virus study were carried out in three cases for Coxsackievirus A16 and Enterovirus 71. The Enterovirus 71 antibody titer were 1:128 in two cases and 1:64 in one case. The Coxsackievirus A16 antibody titer were less than 1:4. This study showed that the causative agents for polio-like paralysis during this period seemed to be the Enterovirus 71 infection.
