122 cases of the genitourinary tract tumors admitted to the Department of Urology, National Medical Center, during the period, Aug. 1968 to July 1975 and the followings are the results. 1. 122-cases(12.8%) were tumor patient among 954 (male 702, female 252) Total admitted patients during 7 years. 2. Age distribution was from 5 months to 83 years showing the highest incidence in the 7th decade (30.3%) and cases over 41 years of age were 99(81.1%) 3. Sex ratio of male and female was 5.4:1(103:19) 4. In 122 cases, 42 cases{34.4%) were benign, 77 cases(63. 1%) were malignant and remainders were uncertain pathologically. 5. Among 122 cases, 57 cases(46.7%) were vesical, 35 cases(28.7%) prostatic, 19 cases(15.6%) renal, 5 cases(4.1%) penile. 3 cases(2.5%) testicular and 3 cases(2.5%) were urethral tumors. 6. Operations were performed in 114 patients (93.5%).

The application of arthroscopic surgery in wrist is not widely advocated because of technical difficulty. We analysed 11(10 patients) wrists of which were performed arthroscopic synovectomy in wrist from July 1991 to September 1992 in Kyung Hee University Hospital. The age of the patients ranged from 23 to 55 years old. Follow up period was from 12 months to 26 months. The application for the arthroscopic synovectomy in that group of patients were based on such disabling clinical symptoms as severe pain, swelling, limitation of range of motion and roentgenographic type from mild to severe stage. Postoperative diagnosis was histologically confirmed with rheumatoid arthritis in nine wrists (nine patients) and gout in two wrists (one patient). The results were assessed subjectively and objectively with pain, swelling and range of motion. Satisfactory overall results were obtained and there were no complications. Conclusively, arthroscopic synovectomy in the wrist is effective produce to relieve pain of the rheumatoid arthritis and gout but arthroscopic synovectomy of wrist is technically demanded.

The relative merits of cartilage scoring versus suturing in techniques for correcting the prominent ear remains a subject of debate among leading plastic surgeons. We compared a variety of echniques for correcting the prominent ear in 72 rabbit ears using scoring, horizontal mattress sutures, and combination scoring and suturing. The ears were splinted with a right-angle fold for 3 postoperative weeks, and the animals were sacrificed after 8 weeks. Suturing techniques in combination with scoring maintained an angulation significantly closer to the desired 90 degrees than cartilage scoring or cartilage suturing only(p<0.05). Histological analysis demonstrated a significant increase in cartilage hyperplasia by suturing alone, whereas the other techniques achieved only mild to moderate increases. We recommend cartilage scoring and suturing through skin incision on severe degrees of prominent ear, and cartilage needle scoring and buried suturing through slit incision on mile-to-moderate degrees of prominent ear.

We have experienced a case of neurofibromatosis with unusual giant pigmentation, which presents itself as a 28 cm x 40 cm sized, serrated bordered light brownish patch speckled with small dark hyperpigmented macules on his back. Histopathologic examinations of light brown patch and speckles showed only an increase in basal melanin pigmentation.

This study was performed to investigate the factors related to tooth wear. For this study, 78 patients with temporomandibular disorders and 76 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the normal group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, head and shoulder posture wee observed clinically. Electromyographic activity of anterior temporalis and masseter muscle were recorded with BioEMG and occlusal status were recorded with T-Scan . Wear facet area of each tooth was measured from working model of upper arch corresponding to the occlusal status from T-Scan, Wear facet area were measured with planimeter in mm2. Total area were divided into incisal, canine, posterior tooth area. Anterior wearfacet area was incisor area plus canine area, and unilateral area was anterior area plus posterior area. The data collected were analyzed by SAS statistical program and the results of this study were as follows: 1. There was no significant difference between the two groups in total werafacet area, and male subjects showed tendency to have larger area in the normal group but female subjects showed tendency vice versa. 2. There was no significant difference related to preferred chewing side and Angle's classification, however, some difference was observed by lateral guidance pattern. Anterior wear facet area in subjects of canine guidance was the largest in the three subgroups. 3. Subjects with head tilting to right side had larger posterior and total area, and subjects with higher shoulder in right side had larger canine and anterior area than any other subgrous. 4. Electromyographic activity of masseter muscle was more correlated with wear facet area than anterior temporalis muscle, and tooth contact number and force were significantly correlated with wear facet area, but the most important factor affecting tooth attrition was age.
