At Orthopedic Department of Kyung Hee University Hospital, we performed 20 total knee replacements in 12 patients who had rheumatoid arthritis and 18 total knee replacements in 13 patients who had osteoarthritis during the period from August 1982 to May 1986. All patients were female. Comparative analysis was done between the two groups with a follow-up period ranging from 1 year to 4 years 8 months, average being 2 years and 3 months. The average age of rheumatoid arthritis patients was 10 years younger than osteoarthritis patients. The improvement of range of knee motion after total knee replacement was greater in rheumatoid arthritis comparing to osteoarthritis. Preoperative flexion contracture was more severe in rheumatoid arthritis than osteoarthritis, but after total knee replacement the average degree of flexion conrcacture was no significant difference between two groups. The average of preoperative Hospital Surgery Knee Rating Scale was low in rheumatoid arthritis group than in osteoarthritis group, but postoperative Knee Rating Scale was similar in both groups. It seems that the problem of wound was more frequent in rheumatoid arthritis than in osteoarthritis.

At Orthopaedic Department of Kyung Hee University Hospital, we performed 50 total knee replacement in 32 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1987. We studied these cases and compared the results of total knee replacement surgery in preoperative ambulatory patients(group I ) with those in preoperative non-ambulatory patients(group II ). 1. Preoperatively, 19 patients were able to walk, and 13 patients were unable to walk. 2. 7 patients of bilateral TKR(36.8%) were included in group I, and 11 patients (86.9%) in group II. 3. The improvement of range of motion after TKR was greater in group II (34 degrees) and in group I, average postoperative range of motion was similar to the average preoperative ROM. 4. Flexion contracture was more markedly improved in group II. 5. In group I, the average preoperative knee rating score by Hospital for Special Surgery rating system was 38.8 and improved to 93.4 postoperatively. In group II, the average preoperative knee rating score was 27.4 and improved to 85.7 postoperatively. 6. Postoperatively most of the patients were able to walk without support except one cases of infection(group I ) and the other who had severe rheumatoid involvements in other joints (group II ). 7. Preoperative evaluation for involvements of cervical spine and surrounding soft tissue structure was necessary endotracheal anesthesia. 8. There was 2 cases of complications in group I, and 4 cases in group II.

Twelve cases with paralytic elbow due to a traumatic lesion of the brachial plexus (eleven cases) and to poliomyelitis (one case) were treated by elbow flexorplasty from April, 1978 to February, 1984 Seven cases with available muscle for transfer were treated by muscle transfer, three cases withwhole arm type brachial plexus injury were treated by gracilis muscle transplantation, and two relatively fresh cases by neurotization. The three operated groups were assessed in range of active elbow motion, muscle power testing, and electromyography at final follow-up. In eight cases, the elbow flexorplasty were augmented by shoulder arthrodesis. The mean length of follow-up was twenty two months. The mean arc of restored active elbow motion was 93 degrees following muscle transfer, 100 degrees following gracilis muscle transplatation, and 35 degrees following neurotization. The overall mean arc of active elbow motion was 77.5 degrees. In the muscle testing, the mean scores of the elbow flexor power were 3+, 4−, and 3− following muscle transfer, grcilis muscle transplantation, and neurotization respectively. The overall mean score of restored elbow flexor power was 3− . The electromyographic findings also revealed corresponding restoration of the action potential in the flexor muscle in the three groups. One case of the transfer group failed after sternocleidomastiod muscle transfer, who subsequently received gracilis muscle transplantation with satisfactory result.

Cyclins are proteins that activate different cyclin-dependent kinases(CDKs) and promote the cell cycles. Their correlations with several human cancers have been identified. Cyclin E, as one of G1 cylins, produces DNA replication through the progression of cell cycle G1 --> S phase. In contrast, cyclin-dependent kinase inhibitors(CDKI) bound with cyclin E-cdk2 complex control the cell cycle and inhibit the cell proliferation. P21(WAF1) proteins, which are CDKIs, are transcripted by a p53 gene and participate in the cell cycle inhibition. Variant p53 proteins produced by a mutated p53 gene lose the ability to control of the cell cycle resulting in cell proliferation. This study is aimed to reveal the expressions of cyclin E, p21(WAF1) protein, p53 variant protein in colorectal adenomas and carcinomas, and also reveal their correlations in the process of carcinogenesis. Twenty-one colorectal adenomas or adenomatous polyps, and thirty colorectal carcinoma tissues were obtained by operative resections or endoscopic polypectomies. Immuno histochemical stains of the above-mentioned three proteins and a statistical analysis of their correlations were made. The results were as follows: 1. P21 proteins were expressed in the upper-one third layer of all normal colonic mucosa, but cyclin E and variant p53 protein were not identified. 2. Cyclin E was expressed in 23.8% of adenomas and 76.7% of carcinomas. Variant p53 protein was expressed in 71.4% of adenomas and 83.3% in carcinomas. The degree of positivity of variant p53 expression was correlated with cancer staging. P21 protein was expressed in all adenomas, similar to normal mucosa, but was not expressed in 43.3% of carcinomas. 3. Expression of cyclin E was increased as to the positivity of variant p53 proteins but the correlations of p21 proteins and cyclin E, and p21 proteins and variant p53 proteins were not identified. Cancer staging was not correlated with the expressions of the three proteins. In conclusion, it can be thought that the overexpression of cyclin E and variant p53 proteins, and the loss of p21 proteins are related with the colorectal carcinogenesis. We can also identify the relationship of cyclin E and variant p53 proteins.

6.Experience of Extracorporeal Shock Wave Lithotripsy (ESWL) with EDAP-LT01: A Report of 660 Cases.
Korean Journal of Urology 2001;42(5):483-488
PURPOSE: Since ESWL had been developed, many experiences of the treatments to urinary stones with various type of lithotriptors were reported. We evaluated the efficacy of EDAP-LT01 piezoelectric lithotriptor according to the size, location of the stone, number of the treatment session, adjuvant therapy and cause of failure. MATERIALS AND METHODS: We retrospectively analyzed the data of 660 cases who had been treated with ESWL. Among the patients, the renal stones were 122, the ureteral stones were 452, and combined with renal and ureteral stones were 43 cases. The mean size of stones was 13mm (range: 4-38mm). ESWL was performed to all the patients with urinary stones except complete staghorn calculi. No anesthesia was performed except in one child (5 years old). RESULTS: Overall success rate was 94.7%, and there were close correlations between the success rate and the size. The mean number of sessions was 2.4. There was no significant complication, but 35 cases were failed by ESWL monotherapy, and auxiliary procedures were done in 21 cases. Efficiency quotient was 0.59. CONCLUSIONS: The ESWL with EDAP-LT01 seems to be effective and safe to treat the urinary stones of various location and size, even compared to the lithotriptors of other type. We also propose that ESWL monotherapy with this machine is efficient for the treatment of the partial staghorn calculi and stones larger than 30mm.

The latissimus dorsi muscle or musculocutaneous flap is one of the most useful flaps in reconstructive surgery. This flap has many advantages, such as its reliable anatomy, long pedicle with large caliber vessels, minimal functional deficit of the donor site, and low incidence of donor site complications. However, the bulkiness of the flap has been considered a disadvantage, so various modifications of technique have been devised. The cutaneous portion of the flap can be safely elevated based on the cutaneous perforating branch of the thoracodorsal vessel. From March 1997 to February 1998, 10 patients underwent reconstructive procedures with thoracodorsal perforator-based free flaps. The composition of the flaps varied in accordance with the nature of the defect. The variances in the flaps were as follows; 3 were cutaneous, 6 musculocutaneous, and 1 osteomusculocutaneous including the rib. All flaps survived with good contour. We concluded that this thin and reliable flap was useful for reconstruction of various defects, and that the composition of the flap, such as subcutaneous, muscle and bone, gave it considerable flexibility as needed.

PURPOSE: The purpose of this study is to evaluate surgical outcomes of canalicular trephination with lacrimal trephine and endoscopic dacryocystorhinostomy in patiens with common canalicular or canalicular obstruction. METHODS: 35 patients (38 eyes) diagnosed as common canalicular or canalicular obstruction undergoing surgery between December 1999 and August 2003. Patients have been followed up more than 5 months after surgery. RESULTS: The average age of patients was 57.3 years old and the average follow-up period was 7.1 months. The overall success rate was 92.1%. With obstructions within lower canaliculus, the success rate was 75.0%. The success rate of the cases with obstructions within upper canaliculus and upper and lower canaliculus was 100%, and the success rate of the cases with obstructions within common canaliculus was 95.2%. CONCLUSIONS: The surgical success rate of canalicular trephination with lacrimal trephine and endonasal dacryocystorhinostomy was better than canaliculodacryocystorhinostomy and this seems to be adequate as an primary procedure before Jones tube bypass surgery.

Familial adenomatous polyposis (FAP) is an hereditary autosomal dominant disease characterized by development of hundreds to thousands of adenomatous polyps in the colon and rectum. The common symptoms are bloody stool, diarrhea, and abdominal pain. The average age at onset of symptoms is 33 years. Because of inevitable progression to malignancy, it is necessary to remove the entire colonic and rectal mucosa. Current surgical options are total proctocolectomy with permanent ileostomy, trans-abdominal colectomy with ileorectal anastomosis (IRA), and restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Recently IPAA can give optimum control of colorectal polyposis in FAP patients with an acceptable incidence of postoperative complications and satisfactory functional results. We experienced one case of FAP who had malignacy in the remained rectum after subtotal colectomy. IPAA was done and the result was satisfactory.
