Chondromalacia patella is a symptom complex characterized by aching pain behind the knee cap, retropatella tenderness that is aggravated by the stair climbing. Malalignment is an important factor causing chondromalacia patella. And to recognize it, is important in the diagnosis and treatment. We studied 3 parameters in the chondromalacic knee and nonchondromalacic knee and the following results was obtained. l. In nonchondromalacic knee, the sulcus angle is 141° 7′ and the congruence angle is −5° 1′ 2. In chonduomalacic knee the sulcus sagle is 139° 2′ and the congruence angle is +5° 3′ 3. In the group with abnormal congruence angle, there was much degenerative changes in the patellofemaral joint. So, it can be inferred that chondromalacia is a precursor of the osteoarthritis and the patient with abnormal congruence angle should be treated actively at the early stage if the conservative treatment had failed.

OBJECTIVES: Objective: Cellular immortality is believed to be a critical step in tumorigenesis. As an important component of the telomere maintenance mechanism, the activation of the enzyme telomerase is tightly associated with cellular immortality and cancer. However, little is known about the status of telomerase during human cervical cancer development. To assess the role of telomerase in the development of malignant transformation of the uterine cervix, this investigation was performed. PATIENTS AND METHODS: Telomerase activity was measured by telomeric repeat amplification protocol(TRAP) assay in 8 cervical intraepithelial neoplasia(CIN) and 24 cervical cancers. The tissue adjacent to the lesions from the same patients was also examined for the presence of telomerase activity. RESULTS: Thirty one of the 32(96.9%) lesions were positive for telomerase activity. In the CIN patients, four of the 8(50.0%) lesions showed moderately to strongly positive activities. In the cervical cancer Ia lesions, five of the 9(55.6%), and beyond the stage Ib lesions, fourteen of the 15(93.3%) showed moderately to strongly positive activities. There was a positive correlation between the grade of the lesion and the telomerase activity(P=0.023). Patient's gravida and telomerase activity also had a positive correlation(P=0.022). CONCLUSION: Relatively weak telomerase activity was detected in the low grade cervical lesion and strong activity was detected in the high grade lesion. There was a progressive increase of telomerase activity in association with an increased degree of cervical lesion. Patient's gravida also had an association with telomerase activity. These results suggest that the expression of telomerase activity may play a crucial role in cervical carcinogenesis.

PURPOSE: To evaluate and compare the difference of predictive post-operative refraction preoperatively and real post-operative refraction among five types of intraocular lens. METHODS: We reviewed retrospectively 567 cataractous eyes that had undergone phacoemulsification or ECCE with posterior chamber intraocular lens (IOL) implantation by the same surgeon. Applied IOLs were AMO(R) Phacoflex(R) II SI40NB, Acrysof(R) MA60BM, Sensar(TM) AR40e, CeeOn(TM) 811B and CeeOn(TM) 720A. Prediction of post-operative refraction (predictive refraction) was calculated by the SRK/T formula with manufactured A constant. Post-operative manifest refraction (real refraction) was done at least 2 months postoperatively. We compared the difference between the predictive refraction and the real refraction by paired t-test. RESULTS: Total studied eyes were 390 eyes. In all groups, more myopic shift were observed than predicted. In AMO(R) Phacoflex(R) II SI40NB group, statistically significant difference was seen in postoperative manifest refraction over the predictive refraction as much as mean 0.46 diopter myopically (p<0.05, paired t-test), but others were not. In the AR40e implanted group, the error of predictive refraction was the smallest among groups. CONCLUSIONS: Prediction of postoperative refractive state was influenced by various clinical factors. Using a revised A constant, predictive error would be decreased. We recommend that every cataract surgeon had better have one's original A constant over each IOL and A constant may be revised when major surgical or biomedical measurement settings were changed.

Since the first report by Tansini in 1896, the latissimus dorsi muscle free flap has been widely used for various types of soft tissue defect due to reliable anatomy with a sufficient diameter of neurovascular pedicle and a sizable muscle. However, for relatively small soft tissue defect, latissimus dorsi free flap offers several distinct disadvantages of donor site including loss of the posterior axillary fold and flattening of the posterolateral chest wall, weakness of upper arm strength in extension, adduction and internal rotation. We treated three patients having various types of soft tissue defect using segmental latissimus dorsi muscular free flap depending on its descending branch of thoracodorsal neurovascular pedicles. There were no serious complications during 18 months of mean follow-up. We concluded that this method has some advantages such as no weakness of strength of the upper arm including walking on crutches, preserving the posterior axillary fold, preventing winging of the scapula and increased chance of using a flow-through technique. Here we present our cases of reconstruction of soft tissue defect using segmental latissimus dorsi free flap with a review of the literature.

Supracondylar fracture of the femur is not as common as the shaft fracture. There is wide range of potential complication in the treatment of these fractures and the method of the treament and the evaluation of it's result is variable and remains controversial. Until 1960, we believed conservative treatment supirior to the operative treatment of the supracondylar fracture of the femur. But recently, anatomical reduction and internal fixation with early joint motion showed satisfactory results and is the trend of treatment of these fracture. The authors of this thesis performed treatment of supracondylar fracture of femur by utilizing Ender nails and screws in 13 cases during the period from October 1987 to November 1988 and it was found that operation was relatively simple, bleeding was little and early exercise of knee was allowed and even for patients of old age internal fixation could be maintained easily.

The mechanical derangement, developmental anomaly, infection amd tumor should be considered as a cause of low back pain in adolescents. Disc herniation in adolescents is very rare and some of that are due to fracture of the epiphyseal ring. We report a case of fracture of the first sacral epiphyseal ring simulating disc rupture.
