Recently, the frequency of meniscal injury of knee has been increasing due to increase of sports activities. It has been known that bucket handle tear is the most common type of the entire injuries of the meniscus. We found 127 cases of meniscal tears and experienced 42 cases of bucket handle tears in the arthroscopic findings from Jan. 1991 to April 1994 in our hospital. We analysed 31 cases which were followed up for at least 1 year. The purpose of this study is to analyse the locking history and frequency, to discuss the several types of bucket handle tear in arthroscopic view, to introduce three portal techniques using posteormedial or posterolateral portal to resect the meniscus, and to analyse our clinical results. So we concluded as follows. 1. Among the 31 cases, 23 cases(74%) had an episode of locking. 2. We found many different types of bucket handle tears in arthroscopic view and the most common type was complete tear in a classic type(11 cases). 3. We were able to resect the meniscal fragment very easily using posteromedial or posterolateral portal. 4. We obtained satisfactory results in 24 cases(77%).

To determine the optimal therapeutic approach for lower ureteral calculi at the hospitals which have not possessed ESWL, we reviewed 85 cases initially treated with expectancy for more than 7 days. Of 85 cases, 37 were treated with expectancy only and the remaining 48 cases received the endourologic manipulations such as stone basket and ureteroscopic removal. A total cumulative spontaneous passage rate at 3 weeks was about 52.9% and the possibility of spontaneous passage of remained stones at 3 weeks was not significant. The spontaneous passage rate was higher in the cases with the stones of small size (less than 6mm), smooth-round shape and without urinary tract obstruction than the other cases. 26 cases were treated with the stone basket and stone extraction rate was only 42.3%. The stone extraction rate was higher in the cases with the stones of smaller size (less than 4mm), irregular-speculated shape and with short duration of previous expectancy than the other cases. A total of 32 cases received the ureteroscopic manipulation and the success rate was 87.5%. Thus, we recommend initial expectancy for up to 3 weeks in the lower ureteral calculi smaller than 10 mm. And after this period, the positive and selective endourological manipulation considering the stone size, shape and expectant duration may be desirable in respect of treatment efficacy.

Fifteen cases of genital warts were examined for the presence of human papillomavirus (HPV) using polymerise chain reaction (PCR). HPV6/11 DNA were found in all cases of genital warts. The PCR based methods described here provide a sensitive, accurate means of detecting genital HPVs.

Iron deficiency remains the most common cause of anemia in infants and chidren despite increasing availability of iron-fortified foods. We screened out anemia in 9-month old infants in well baby clinic to know the prevalence of anemia and the weaning status. The results were as follows: 1) Among 345 infants screened, 24 infants (7%) were found to have anemia. 2) The kind of anemia was microcytosis and 7 infants (2.2%) revealed hypochromia. 3) Among the remaining 311 non-anemic infants, 6 infants (1.9%) revealed microcytosis and 7 infants (2.2%) revealed hypochromia. 4) In anemic group the mean hemoglobin concentration was 8.75+/-1.03gm/dl, hematocrit was 27. 73+/-3.11%, MCV was 65.84+/-8.21 fL, MCHwas 20.95+/-2.93 pg and MCHC was 31.34+/-1.89 gm/dl. 5) In 9 anemic infants, weaning was delayed until 9 months of age.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

PURPOSE: To evaluate the findings and the role of contrast enhanced magnetic resonance imaging in avascular necrosis of femoral head. MATERIALS AND METHODS: Sixteen patients with avascular necrosis of femoral head were examined with MRI. Tl-weighted and T2-weighted images and contrast-enhanced Tl-weighted images were obtained. Enhancing characteristics of the necrotic area and synovium were determined. Also a change of the disease extent after enhancement was assessed. RESULTS: Twenty seven avascular necrosis of the femoral head including 11 cases of bilateral lesion were detected. Fifteen cases revealed collapse of the femoral head. The portions of the lesion with low signal intensity on Tl-weighted images and high signal intensity on T2-weighted images showed contrast enhancement in 15 cases. However, the portions with low signal intensities both on T1 and T2-weighted images showed enhancement in one case. There was no significant change of the disease extent after enhancement. Synovium showed enhancement in 18 cases, and joint effusion was detected in 23 cases. CONCLUSION: Contrast enhanced MR images may be helpful in predicting histopathologic findings of avascular necrosis of the femoral head, but not useful for evaluating the extent of disease.
