PURPOSE: This study was done to determine how a hospital life guidance movie enhanced the understanding of hospital life by elderly in-patients. METHOD: A non-equivalent control group post-test design was used for the study. The experimental group watched a movie on guidance for hospital life while an in-patient control group read corresponding guidance booklets. The understanding and satisfaction from the respective programs for the two groups were surveyed with a questionnaire. The data were analyzed using SPSS. RESULTS: The group which watched the movie had a better understanding of hospital life than the group which read the booklets. The patients who watched the movie also expressed more satisfaction with their guide program than the patients who only read the booklets. Understanding of hospital life had relevance to satisfaction with the given program. CONCLUSION: The results of this study suggests that a movie on hospital life provides better guidance which helps the prospective patients understand and adapt better to their hospital life. Therefore, this type of movie is considered to be an effective medium to provide guidance to elderly in-patients.

In patients disabled by severe rheumatoid and degenerative arthritis of both knees, bilateral total knee arthroplasty(TKA) afforded much functional improvement in pain relief and function. Postoperative results of bilateral TKA was described as being similiar to those observed among patients with single joint replacement. The purpose of this study is to evaluate the etiology and postoperative result of bilateral TKA performed on 32 knees in 16 patients at Department of Orthopedic Surgery, Seoul National University Hospital from Mar. 1985 to Oct. 1988. In our series, there were 15 females and only 1 male, their mean age was 53 years. Duration of follow up was ranged from 1 to 4 years and 5 months being average 1 year and 6 months. The results were as follow. 1. Cheif complaints were pain in 18 cases(100%) and difficulty in walking in 15 cases(82%). 2. Preoperative etiology was rheumatoid arthritis in 11 cases and degenerative arthritis in 7 cases. 3. Knee joint function by HSS(Hospital for Special Surgery) knee rating score was increased from 44.6 points preoperatively to 81.2 points postoperatively. 4. The tibiofemoral angle was changed from 1.4 degree varus to 4 degree valgus. 5. The prothesis type used were PFG(Press Fit Condylar) in 22 knees, Miller-Galante in 8 knees, AMK in 3 knees, PCA in 2 knees and unicompartmental type in 1 knee. 6. Complication were 1 case of knee fusion due to concomittant tuberculous arthritis and mild joint effusion in 6 knees. 7. Bilateral one-stage arthroplasty may be considered as an alternative procedure.

Rheumatoid arthritis is a chronic inflammatory systemic disease of young or middle aged adults, characterized by destructive and proliferative changes in the synovial membrane, periarticular structures, skeletal muscle and perineural sheath. Eventually, the joints are destroyed, ankylosed and deformed. Therfore, the aim of treatment is to keep the inflammatory process at a minimum, thereby preserving the joint motion, maintaining the health of muscle supplying motor power about the joint and preventing secondary joint stiffness and deformity. Surgical treatment in rheumatoid arthritis has progressed and there have been advances in the relief of pain and increase in the range of motion. Among them the results of total knee arthroplasty (TKA) have improved steadily during the past decade due to refinements in design, fixation, and surgical technique. At orthopedic department of seoul national university hospital, we performed 31 total knee replacement in 18 patients who had suffered from rheumatoid arthritis during the period from Aug. 1982 to Dec. 1988. Following results were obtained. 1. Knee score increased from 37.8 to 76.9. 2. Tibio-femoral angle was corrected from 0.9° valgus to 5.3° valgus. 3. Conplications were peroneal nerve palsy in 3 knees, instability in 1 knee, tuberculous arthritis in 1 knee. 4. In 25 out of 31 knees, good functional results were obtained.

To develop an animal model of nephrolithiasis similar to the pattern of human renal stone disease, we adopted a protocol of administration of stone substrates along with induction of renal tubular injuries. Male Wister rats fed with 3% ammonium oxalate containing chows with or without additional 40 mg/kg/day of gentamicin for 8 days were compared with those fed with normal chows. On dissecting microscopic examination, rats receiving oxalate and gentamicin showed more crystals and plaques than rats receiving oxalate only, both in 15 days and 22 days after feeding, and most of the crystals were located at renal papilla. Average score of crystal abundance was 0.4, 1.15, respectively in rats receiving oxalate only and oxalate plus gentamicin after 15 days of feeding, and 0.9 and 1.55, respectively after 22 days. Little crystals were found in rats fed with normal chow with or without gentamicin. Urinary excretion of tubular epithelial brush border enzyme, gamma-glutamyl transpeptidase(GGT), was increased by gentamicin administration whereas creatinine clearance rate was not changed. Urinary excretion of oxalate was unchanged, but calcium and uric acid was markedly decreased in rats fed with oxalate and formed crystals, and citrate and magnesium excretion was also decreased. These results indicate that administration of oxalate along with inducing renal tubular damages by subcutaneous injection of gentamicin seems to form crystals and plaques in the kidney more rapidly and abundantly than feeding with oxalate alone.

The purpose of this in vitro study was to compare the effects of root canal debridement following rotary Ni-Ti instruments with positive versus negative rake angle. Seventy sound, extracted human anterior teeth & premolars were randomly divided into four groups. The used rotary instruments were Ni-Ti HERO 642(Micro-Mega in France, 20 specimen), Ni-Ti ProFile(Maillefer, Ballaigues, Switzerland, 20 specimen), stainless steel engine reamer(Mani, Matsutani Seisakusho Co.,Japan, 20 specimen) and negative control group(10 specimen) was only extirpated with barbed broach(Mani, Matsutani Seisakusho Co.,Japan) Group 1 & 2 teeth were prepared to a #40 at the apex followed by 1 mm using crown-down technique. Group 3 teeth were instrumented from a #15 to a #40 in sequential order. After preparation and final irrigation, the roots split longitudinally into a bucco-lingual direction. Root halves were cross-sectioned in apical third portion again. all root specimens were prepared for SEM investigation & photographed. Separate evaluations were undertaken for smear layer on prepared walls with a five score-index for each using reference photograph in root halves. the penetration depth of smear layer into dentinal tubules was also estimated in the other halves. the following results were obtained : 1. Smear layer was observed on all the prepared walls with three experimental groups except negative control group 2. Smear layer characteristics 1) HERO 642 groups showed snowy & dusty appearance & were observed only few some dentinal tubuli open on the prepared walls, and the penetration depth of it into dentinal tubules may be 1-2 microm thick. 2) ProFile groups showed shiny & burnished appearance & complete root canal wall covered by a homogenous smear layer with no open dentinal tubuli and penetration depth of it into dentinal tubules may be 1-2 microm thick. 3) Engine reamer groups showed obviously file's passed tracks on the prepared walls & were observed complete root canal wall covered by a homogenous smear layer with no open dentinal tubuli. The results revealed that a completely clean root canal could not be achieved regardless of positive & negative rake angle, which is in accordance with the majority of studies on root canal cleanliness. In conclusion, throughout irrigation with antibacterial solutions or chelating agents is recommended to remove the smear layer on prepared canal walls.

The Nuss procedure has good cosmetic effects, but it could be cause of bleeding and organ injury during dissection of the anterior mediastinum. We have made an effort to overcome the defects of the traditional method through the anterior mediastinum, thus we developed a transilluminated introducer that made it safer and simpler to operate within a 1 cm incision only. A total of 67 patients underwent the Nuss procedure using the transilluminated introducer. Thirty-six patients underwent the procedure with the transilluminated introducer only (age<14 years). Thirty-one patients had an additional thoracoscopy (age> or =14 years). There were no major complications, such as massive bleeding or organ injury in the thoracic cavity during or after the Nuss procedure. Our findings demonstrated that the anterior mediastium could be dissected simply and safely by the use of a transilluminated introducer during the Nuss procedure without fatal major complications, such as bleeding and organ injury.

We performed microscopic sperm aspiration and IVF in 2 cases of distal vas obstruction. 4 cases or epididymal obstruction, 3 cases of congenital vas aplasia. The results were as follows ; 1. The fertilization was successful in 2 cases of distal vas obstruction(100%). 1 case of epididymal obstruction(25%). 1 case of congenital vas. aplasia(33.3%). 2. In 4 cases with Sertoli cell failure. the count and quality of aspirated sperm was lower than in 5 cases with normal hormonal study. The fertilization was successful in 1 case with Sertoli cell failure(25%) and 3 cases with normal hormonal study(60%). In conclusion. microscopic sperm aspiration and IVF proved helpful in treatment of patients with distal vas obstructin, congenital vas aplasia. but the vasoepididymostomy proved more helpful in treatment of patients with epididymal obstruction then microscopic sperm aspiration and IVF until now. When microscopic sperm aspiration and IVF is performed, it seems that in Sertoli cell failure group. there will be lesser fertilization success cases than in normal hormonal study group.

PURPOSE: We evaluated the therapeutic efficacy of finasteride in the treatment of hemospermia, especially in prostatitis-related hemospermia. MATERIALS AND METHODS: Among the patients who visited our urologic department due to hemospermia from Jan 2000 to Oct 2003, 46 patients enrolled in the study. Semen analysis, expressed prostatic secretion, and transrectal ultrasonography were performed for all patients, and we determined whether or not the hemospermia was caused by inflammatory chronic non-bacterial prostatitis. We sorted all the subjects into 2 groups by the use of finasteride or not. We sub-divided the 2 groups by the presence or absence of prostatitis. In each of the 4 groups, the results were compared. Results were also recalculated after excluding sonographically abnormal cases. RESULTS: In the 35 finasteride-treated patients, the prostatitis group showed a 75% (12/16) success rate whereas the non-prostatitis group showed 31.6% (6/19) success. This difference was statistically significant (p=0.01). In the 11 non-finasteride patients, there was no difference in success rate between the prostatitis group (57.1%) and non-prostatitis group (50.0%). After excluding 15 sonographically abnormal patients, the finasteride-prostatitis group showed an 80% (8/10) success rate whereas the non-prostatitis group showed a 25% (3/12) success rate. CONCLUSIONS: Finasteride treatment in hemospermia was more successful in prostatitis than non-prostatitis patients. Efficacy was more prominent after excluding sonographically abnormal cases. Finasteride could be an useful agent in the treatment of prostatitis-related hemospermia. More extensive study is needed.

Kasabach-Merritt phenomenon does not occur with common hemangioma, rather it is associated with the more aggressive Kaposiform hemangioendothelioma and rarely with other vascular neoplasm. We report the case of an adult who was diagnosed as Kaposiform hemangioendothelioma complicated by Kasabach-Memtt phenomenon. This is the first report in Korea of an adult with Kasabach-Merritt phenomenon who has osteolytic changes of femur, pelvic bone, and lumbar spine.
