An experimental study of the tensile bonding strength of acrylic bone cement was carried out by using the tubular bones of 12 mongolian dogs. Following observations were made: 1. The later the cementing stage, the weaker was the tensile bonding strength of bone cement. 2. When saline or synovial fluid was interposed between the contact surfaces of the recipient bone and the cement, the tensile bonding strength of bone cement decreased by more than 50% of that when the bonding surface was dry. 3. When the bonded bone was stored in Hartmans solution, the tensile bonding strength of bone cement was reduced to 15–25% of the strength when stored in air.

BACKGROUND AND OBJECTIVES: Idiopathic restrictive cardiomyopathy is a very rare and poorly recognized disease in children. This study is performed to describe the clinical course and to define potential predictors of outcome. MATERIAL AND METHOD: We reviewed the medical records and diagnostic studies of 11 consecutive patients during the period from Jan.1991 to Aug. 2000. RESULTS: The age at diagnosis was 1.2-13 years (median 7 years) and the duration of follow up was 3-90 months (median 3.6 years). All except one were symptomatic (dyspnea in ten, chest pain in four). The chest pain was associated with significant ST depression on both resting and exercise ECG, suggesting myocardial ischemia. Two had complete heart block as either initial or terminal event. Cardiac catheterization was done in nine ( mean pulmonary arterial wedge pressure 23+/-6mmHg, systolic pulmonary arterial pressure 47+/-14mmHg, mean right atrial pressure 11+/-9mmHg). Echocardiographic dimensional ratio of left atrium and aorta (LA/Ao) was 2.41+/-0.58. Mitral E/A inflow ratio was 2.72+/-1.42, E wave deceleration time was 93.6+/-44.2ms. During follow up, six died. The 2 year and 5 year cumulative survival rates were 54.5% and 18.8% respectively. The predictor for nonsurvivor were pulmonary venous congestion and LA/Ao >2.5(p<0.05). Verapamil was tried in 6 cases without favorable effect in all. CONCLUSION: Considerable numbers of restrictive cardiomyopathy have myocardial ischemia associated with ST depression and chest pain. The patients with pulmonary venous congestion and severe left atrial enlargement (LA/Ao>2.5) were at risk for death, requiring prompt definitive treatment such as cardiac transplantation.

To investigate the maternal and child factors associated with early detection of cerebral palsy, 74 mothers of cerebral palsy children who were born since January 1, 1980 and being treated at Taegu Rehabilitation Center for the Handicapped, Rehabilitation Center of Taegu University, St. Paul Children's House and Pusan Welfare Association of Cerebral Palsy Children were interviewed from February to April 1987. There is no association between age of child when parents noticed the child's abnormality and educational level of father but it tend to be detected earlier when education level of mother is college or above compared with high school or under. There is a trend of earlier detection of child's abnormality although statistically not significant in case father is professional or managerial worker, monthly income of father is over 610,000 won, child is first-born, age of the parents is 34 years or under, child is a boy, and child has periodic well-baby check-up. The child's abnormality is detected earlier when mothers had 7 prenatal visits or more compared with those who had 6 visits or less (P<0.05). Parents noticed the child's abnormality first in 85.1% of the case whereas doctors detected it first in 2.7% and this percentage was not different whether the child had periodic well-baby check-up or not. The first physician's diagnosis of the children was cerebral palsy in 36.5% and the rest was normal, need for observation, uncertain, etc. Parents took the child to doctor for diagnosis 2-3 months after they noticed the child's abnormality and after the child was diagnosed as cerebral palsy parents either took no therapeutic measure or brought the child to physiotherapy or acupuncture or gave herb medicine before they started specific rehabilitative therapy. For early detection of the cerebral palsy children, teaching of evaluation method for child development should be reinforced both in medical school and clinical training course and should train the specialist for diagnosis and treatment of crippling conditions. Also, public education needed for the importance of early detection of crippling conditions and currently available methods for diagnosis and treatment.

Pulmonary atresia with major aorto-pulmonart collateral arteries(abbreviated as MAPCA in the following)as a route for pulmonary blood flow presents many problem in diagnosis and management and recently new approach to surgical management (unifocalization)was suggested and few reported it's application. Nineteen cases who had pulmonary with MAPCA, diagnosed at Seoul National University Children's Hospital from October 1987 to May 1989, were studied to lool at the relationship between MAPCA, central pulmonary artery and segmental pulmonary arteries. Also was observed the clinical course and operative management. The average number of MACPA in each patient was 4, two toward right lung and the other two toward left lung. MACPA arose most frequently from descending aorta and innominate artery contralateral to the side of aortic arch. Central pulmonary artery was identified in 86.7%. The number of bronchopulmonary segment connected to central pulmonary artery directly or indrectly was very variable so was the number of bronchopulmonary segment connected to MAPCA only. Three had a total correction and 14 had a various kinds of palliative operation once or twice. Seven had a called "unifocalization"(connection of MAPCA to central pulmonary artery) to correct arborization abnormality but the result was not satisfactory for technical reason.

A total of 322 patients with endobronchial tuberculosis (8.1%) out of 3,982 subjects who had a flexible fiberoptic bronchoscopic examination at the Department of Pulmonary Medicine of Hanyang University Hospital between the beginning of March 1982 and the end of Apr11 1996 were included in this study. The peak incidence occurred in the second decade, and the male to female was 1 : 3.0. The barking cough with variable amounts of sputum was the most common chief complaint in 56.9% of the 313 patients. Other complaints included dyspnea, chest pain, fever, hemoptysis, and generalized weakness. Localized wheeze was heard over the chest in 16.9% of the 313 patients. Infiltration/consolidation was the most common roentgenographic finding of the chest in 64.2%. Bronchoscopically, hypertrophy with luminal narrowing was the most common findings in 32.3% of the 322 patients and left main bronchus was the most frequently involved in 24.0%. Using fiberoptic bronchoscopy allows not only substantial meaningful assessment of endobronchial tuberculosis but also makes a differential diagnosis of lung cancer in older patients. We need further evaluations of standard bronchoscopic classification of endobronchial tuberculosis, diagnostic accuracy of endobronchial tuberculosis by PCR, a large prospective study of effects of corticosteroids in endobronchial tuberculosis patients, and appropriate treatment of atelectasis by endobronchial tuberculosis.
