It is generally accepted that the integrity of posterior cruciate ligament plays a major role in knee stability. The rotatory movement is around a point to the back of center of joint where the posterior cruciate ligament lies, and it is a structure which is just as important as the other ligaments. Methods of reconstruction have been described, using semitendinosus tendon, gracilis tendon, popliteus tendon, patellar tendon, iliotibial band, and medial meniscus. We have successfully used the semitendinosus tendon in two patients who sustained neglected rupture of posterior cruciate ligament.

OBJECTIVE: This study was done to evaluate the risk factors and prevalence of symptom-giving pelvic girdle relaxation in pregnant women. METHODS: Three hundreds thirty-two postpartum women were asked to fill out a questionnaire within one week after their parturition. The diagnostic criteria of this lesion were adopted from the Norwegian Medical Association's and Larsen's criteria. The questionnaire were included age, parity, BMI(kg/cm2), weight gain during the pregnancy, history of symptom giving pelvic girdle relaxation in previous pregnancy, level of exercise and vocational status during and before the pregnancy and baby's birth weight. The answers were evaluated to determine the risk factors. The correlation was tested by student t-test and logistic regression. RESULTS: The prevalence of symptom-giving pelvic girdle relaxation during pregnancy was 18.9%. The history of symptom-giving pelvic girdle relaxation in previous pregnancy, multiparity and the absence of regular exercise before and during pregnancy showed correlation with symptom-giving pelvic girdle relaxation in pregnancy (p<0.05). CONCLUSION: It is suggested that women who experienced symptom-giving pelvic girdle relaxation in previous pregnancy should be checked for this lesion before pregnancy. Regular exercise is required to lower the incidence and lessen the severity of this lesion in pregnancy.

Authors report the radiologic findings of two cases of multiple bile-duct hamartoma in the liver. Ultrasonography and computed tomography of the liver were performed in two female patients. In one patient, ERCP was performed. Ultrasonography and computed tomography showed scattered multiple hypoechoic and low attenuated lesions, measuring up to 2cm in both lobe and ERCP showed communication of these lesions with the biliary system. Multiple bile-duct hamartoma should be included in the differential diagnosis of multiple small cystic lesions in the liver.

BACKGROUND: Osteoporosis is a skeletal condition that is characterized by reduction in bone volume and an increased vulnerability to fracture, practically of the proximal femur and vertebrae. But the etiology of osteoporosis in most men without history of alcohol abuse, or glucocorticoid excess is unknown. Several studies revealed that bone density in aged men was associated with serum sex steroids or sex hormone binding globulin (SHBG). METHODS: We have analyzed bone density and sex steroids, and SHBG of healthy 100 middle aged men who visited one university hospital located in Taejon city from Jan. 1997 to Nov. 1997. Aim of this study was to determine whether bone density in middle aged men was associated with serum sex steroids or SHBG. RESULTS AND CONCLUSION: Body mass index was significantly associated with serum FEI. BMI also associated negatively with SHBG. Bone density at lumbar spine was significantly positively associated with FEI (Free Estradiol Index) (r=0.359, P<0.001). SHBG was negatively associated (r=-0.273, P<0.01) with lumbar bone mineral density. After controlling for age, FEI and SHBG were still associated with BMD of lumbar spine. Because of these associations, multiple stepwise regression models were constructed, and accounted for 12-17% of the variability in bone density. Also, these results showed consistent, significant positive associations between bone density and FEI, BMI in middle aged men. Therefore, our data suggest that FEI and BMI may play an important role in the maintenance of the male skeleton.

OBJECTIVE: To report the prevalence of lupus anticoagulants and anticardiolipin antibodies in patients with recurrent spontaneous abortion and infertility. MATERIAL AND METHOD: Lupus anticoagulants and anticardiolipin antibodies were analyzed by Diluted Russell's Viper Venom Test (DRVVT) and solid phase enzyme immunoassay, respectively. RESULTS: In 200 patients with infertility, there were 6 cases (3%) with positive lupus anticoagulants or anticardiolipin antibodies. Of these, 3 patients (1.5%) showed positive lupus anticoagulants and anticardiolipin antibodies, respectively. In 120 patients with recurrent spontaneous abortion, there were 13 cases (10.8%) of positive lupus anticoagulants or anticardiolipin antibodies. Of these, one patient (1%) showed lupus anticoagulants and 12 patients (10%) showed anticardiolipin antibodies. But in two groups, there was no cases with positive lupus anticoagulants and anticardiolipin antibodies. CONCLUSION: Lupus anticoagulants and anticardiolipin antibodies are definite cause of recurrent spontaneous abortion. There has been a speculation that they might be associated with infertility and repeated IVF failures. But it was found that the role of lupus anticoagulants and anticardiolipin antibodies in these cases are not clear.

Rhabdomyosarcoma are reportedly the most common soft tissue sarcoma occuring in childhood, but the biliary tree is a rare site of origin for this tumor. Recently we experienced a case of embryonal rhabdomyosarcoma of the biliary tree in a 30-month-old child. UItrasonography showed hypoechoic mass filling the dilated left. intrahepatic & extrahepatic bile ducts, and CT showed hypodense mass with heterogeneous enhancement after contrast infusion. Intraoperative cholangiography showed filling defects within the dilated left. intrahepatic & extrahepatic bile ducts. Postoperative MRI showed residual mass within the left. intrahepatic duct which was hypointense on T1WI and hyperintense on T2WI.
