This study was designed to evaluate the results of anterior cruciate ligament(ACL) reconstructions with ligament augmentation device(Kennedy LAD; 3M Co., St. Paul, MN, USA) in chronic injury. Eighteen patients with chronic ACL insufficiency were treated by ACL reconstruction using bone- patellar tendon-bone/LAD composite graft. The patients were followed up more than 5 years and the lat- est follow-up results are presented here. Evaluations were based on the Lysholm functional score, Lachman test and pivot-shift test. Data were analysed using the SPSS software. There were 9 patients(50%) with a Lysholm score more than 84(excellent or good) at latest follow-up. This postoperative improvement of Lysholm score was sta- tistically significant, P=0.001. There was no serious perioperative complications. Rehabilitation was not prolonged. This study demonstrated that a synthetic graft augmentation may improve results. However, no significant advantages have been observed with the use of LAD to augment patellar tendon. The com- parison study of ACL reconstruction with and without Kennedy LAD is recommended to assess the possi- ble effects of the addition of the LAD. And routine use of LAD should not be advocated in uncomplicated reconstruction of ACL using biological graft.

BACKGROUND: Noninvasive estimation of pulmonary artery pressure is an important component of echocardiographic studies. A number of methods are available for estimation of pulmenary pressure, each with varying degrees of reported accuracy. To assess accuracy and difficulties, noninvasive pulmonary artery pressure estimates were performed in infants and children with congenital heart diseases. METHODS: Noninvasive estimates from 8 methods were compared with catheterization measurements. Systolic pressure was estimated by the Burstin method and from perak tricuspid regurgitation velocity, and also from systolic pressure gradients through the VSD(ventricular septal defect) and PDA(patent ductus arteriosus). Mean pressure was estimated by acceleration time divided by ejection time measured from Koppler spectrum obtained at the right ventricular out flow tract. Diastolic pressure was estimated from pulmonary regurgitation velocity spentrum at end-diastolic, and also from diastolic pressure gradient through the patent ductus arteriosus. RESULTS: IN systolic pressure, Burstin and tricuspid regurgitation velocities estimates correlated significantly(r=0.92, 0.90 respectively), whereas VSD and PDA estimates correlated less well with catheterization estimates(r=0.83, 0.65 respectively). The mean pressure, measured from RVOT(right ventricular outflow tract) Doppler spectrum corresponded well with catheterization pressure(r=0.89), whereas those obtained from the main pulmonary artery correlated less well(r=0.74). The diastolic pressure estimates from pulmonary regurgitation velocity spectrum, revealed good correlation(r=0.79), but those from diastolic Doppler spectrum at PDA correlated less well with catheterization estimates(r=0.63). CONCLUSION: All of eight Doppler echocardiographic methods seemed to be easily performable for estimation of pulmonary artery pressure. But, the degree of accuracy was variable. Because a pressure estimante from only a single method may be in error, care should be taken in combining use of other(one or two) methods.

PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.

OBJECTIVES: The purpose of this study is to examine the psychosocial and obstetric factors associated with postpartum depressive symptoms in Korea. METHODS: At the 1-week and 4-week postpartum visit, 61 postpartum women completed Edinburgh Postnatal Depression Scale (EPDS), Beck Depression Inventory (BDI), Stait-Trait Anxiety Inventory (STAI), and Symptom Check List-90-Revised (SCL-90-R). Data related to psychiatric and obstetric characteristics, pregnancy and delivery related events were collected from standard medical records. 42 women without a history of pregnancy or delivery within 6 months were recruited as a control group. The postpartum group were divided into depressive and non-depressive groups according to the EPDS and BDI results of 4-week postpartum. RESULTS: Compared to the normal control group, the mean scores of EPDS and BDI at 1-week postpartum were significantly higher (p<.05 and p<.01, respectively) in the postpartum group. The postpartum group also scored significantly higher in the somatization, psychoticism, and global severity index profiles according to the SCL-90-R results (p<.05). The mean score of BDI at 4-week postpartum was significantly higher (p<.01) in the postpartum group. There were significant correlations (p<.01) between the EPDS and BDI reports at 1- and 4-week postpartum. The rates of having experienced severe emotional stress during pregnancy and of smokers and drinkers before pregnancy were significantly higher (p<.05) in the postpartum depressive group (EPDS > or =10 and BDI > or =10) compared to the postpartum non-depressive group. The rate of having experienced depressive symptoms at 1-week postpartum was also significantly higher in the postpartum group. The depressive symptomatology at 1-week postpartum was identified as a significant risk factor for the depressive symptoms of 4-week postpartum when multiple logistic regression analysis was performed after controlling for age and education level. CONCLUSION: These findings suggest that postpartum women in Korea have many psychiatric problems such as depressive mood and somatization which necessitate proper care and assessment during the early postpartum period. Stress management during pregnancy may be helpful as a measure of preventing postpartum depression.

PURPOSE: This study was aimed to determine the relationship between osteopontin(OPN) and osteoclast, especially focused on whether ostecolast could produce osteopontin or not. MATERIALS AND METHODS: Osteoclasts were isolated from the giant cell tumor of proximal tibia and seeded on the 13 mm round cover slip resided in 24 multi-well plates for culture. After 2 days, osteclasts on the cover slip were fixed with cold acetone for 3 minutes and immunocytochemistry was done with rabbit osteopontin antibody. For in situ RT-PCR, osteoclasts on the cover-slips were fixed with 4% paraformaldehyde for 4 hours and were treated to pepsin. PR-PCR was done and the PCR producst were stained with anti-digoxigenin-AP. RESULTS: Osteopontins were found on the surface of the osteoclast by immunocytochemistry, and intense osteopontin mRNAs were found by in situ RT-PCR. CONCLUSION: We have identified that osteoclast could synthesize the osteopontin, and confirmed that in situ RT-PCR was a very useful method in expressing small amount of mRNA in case of mixed cell culture. Further study was needed to identify the action of the osteopontin produced by the osteoclast.
