INTRODUCTION: Sleep has numerous important physiological and cognitive functions that may be particularly important to elite athletes. Sleep deprivation can have significant effects on athletic performance. However, there are few published data related to the amount of sleep obtained by elite athletes. We investigated sleep patterns of Korean women golfers using sleep-related questionnaires. METHODS: For this study, 98 Korean university women golfers and 46 age- and sex-matched controls were recruited. All subjects were asked to complete the self-administered sleep questionnaire consisting of questions about habitual sleep patterns (sleep onset time, sleep latency, awakening time in the morning, day time napping time), exercise habits, Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISS), Pittsburgh Sleep Quality Index (PSQI), validation of the Perceived Stress Scale (PSS), and Beck Anxiety Inventory (BAI). RESULTS: The sleep onset time was significantly earlier (pm 23 : 05 +/- 00 : 52 and 00 : 14 +/- 00 : 51 ; t = 5.287, p < 0.001), the waking time was later (am 07 : 21 +/- 01 : 09 and 6 : 35 +/- 00 : 32; t = -2.715, p = 0.008), the weekday total sleep time was greater (417.77 +/- 78.18 minute and 351.52 +/- 77.83 minute ; t = 4.406, p = 0.001), and the daytime nap time was greater (77.73 +/- 41.28 minute and 20.22 +/- 33.03 minute ; t = 7.623, p < 0.001) in the golf athletes compared to the controls. The PSQI scores were significantly lower, but estimated sleep latency and ESS, ISS, PSS, and BAI scores were not different among the two groups. CONCLUSION: This study suggests that Korean university women golfers have good sleep patterns resulting in no difference in sleep-related stress compared to age- and sex-matched control students.

Achilles tendon is the most powerful and the biggest tendon of the body and its rupture is frequently sports-related. Many authors reported the effects of mobilization, electricity, ultrasound and various drugs as factors influencing the injured tendon. We studied the effects of early passive mobilization after firm suture using plantaris tendon as tension suture material and reinforcing membrane on the repair of a ruptured Achilles tendon. From March 1992 to December 1995, twenty-two operations on the Achilles tendon were carried out in our hospital. 1. Fourteen patients were male and eight patients were female. The mean patient age was 38 years, ranging from 13 to 68 years. Average follow-up periods was 2 years and 7 months, ranging from 12 months to 3 years and 8 months. 2. The rupture site was 4.7cm proximal to the tendon insertion into the calcaneus on average. 3. We performed the operations with end to end suture technique. After approximation of the ruptured ends of the tendon with a No. 5 Ethibond tension suture using a modified Kessler stitch, placed plantaris tendon in a fascial needle and pass it circumferentially and distal plantaris tendon is fanned out and tacked over the repair. 4. Postoperative treatment was done as following protocol Short leg cast was done with equinus position for initial 3 weeks, and then cast was removed, hydrotherapy and passive exercises was employed. About 6 weeks after operation when the foot can be brought to right angle, a reverse 90degrees ankle stop short leg brace was applied for additional 6 weeks and partial weight bearing was aUowed. 5. Follow-up results were classified according to the Arner-Lindholm scale. We had 16 excellent results and 6 satisfactory results. After rigid suture it may be possible to introduce a regimen of progressive isometric stimulation and protected loading and streching combined with removable orthosis. Such early exercises are likely to improve the rate of rehabilitation over plaster immobilization.

Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection (prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricture, impacted stone, Cunningham clamp or condom catheter) and trauma (instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors, 1) a ureteral or bladder calculus that is lodged in the urethra 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum combined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

The elbow is the most frequent area of complaint in children and adolescent baseball players. The physical stresses associated with repetitive throwing create extra-ordinary forces, which may affect the normal osteochondral and soft tissue developmental process and are the important factors causing the decrease of competitive power and shortening of life as a baseball player in adolescents. We surveyed the 114 baseball players of middle & high school in Taegu in order to evaluate the prevalance of symptoms and radiologic findings of the elbow and correlation of these findings to career & position of the baseball game. The results were as follows. 1. Of 114 players, 83 were non-pitchers and 31 were pitchers. The mean career was 3.8 years (7 months to 6 years). 2. The 77 players (67.7%) had the pain on their elbow during or after daily exercise. Other clinical symptoms were locking (30.7%), limitation of motion (18.4%), swelling (16.6%) and clicks on motion (10.5%). 3. On the radiogram of the elbow, hypertrophy or separation of medial epicondyle were seen in 34% of players, loose bodies in 17%, hypertrophy of the humerus in 12% and cystic change of the capitellum in 11%. 4. The mean career of symptomatic players was 4.4 years but non-symptomatics was 2.7 years. The mean career of players who had abnormal radiologic findings was 5.1 years but 3.1 years in players who had no abnormal radiologic fingings. 5. Symptoms and pathologic changes were more common in the elbow of pitcher' s group due to throwing frequency & pitching style. 6. Among the 77 players who had any kinds of problem of the elbow, 49 players of them had no experience of visiting hospital. 7. To prevent these injuries of the elbow, the following recommendations were made. First, restrict the number of innings pitched per game. Second, avoid throwing the curve ball in this age group. Third, ensue an adequate warm up period before exercise or rest after games. Fourth, inform parents and coaches of possible harmful nature of excessive throwing.

We developed Extor pins for Extor external fixator, it made of stainless steel and applied it clinically to manage open fractures and chronic osteomyelitis from December, 1993 to January, 1995. The main aim of present study is to compare the mechanical strength and biocompatibillity between Extor pins and AO Schanz pins, and to determine the safety and possibility of clinical use. We performed the biomechanical test for bending, tension, and shearing of pin itself using universal testing machine (LR5OK) and pullout test in cadeveric cortical femur to determine the bone holding power. There was no significant difference between Extor and AO Schanz pin (p>0.05). Clinically, the incidence of pin site infection, pin lossening, radiological rarefaction, and pathological change were not different significantly (p>0.05). Although Extor pins are somewhat different from AO Shanz pins in material and design characteristics, we can find the safety and possibility of clinical use of Extor pins made in Korea.

The trend in chemotherapy of bladder carcinoma has evolved from the single agent to the combination chemotherapy. In 1985 Sternberg et al. reported 71 per cent of significant tumor regression and 50 per cent of complete clinical remission with M-VAC(methotrexate, vinblastine, adriamycin and cisplatin) combination chemotherapy of treatment for advanced urothelial transitional cell carcinomas. Therefore, the effects of neoadjuvant systemic M-VAC chemotherapy in 23 patients with bladder carcinoma at the Department of Urology, Chonnam University Hospital from January 1987 to June 1989 were evaluated. The following results were obtained. 1. The average number of cycle were 2.1 and the cycle length varied from 28 days to 52 days (average: 32.8 days). 2. Clinical complete and partial remission rate were obtained in 11 patients( 47.8 per cent), while 6 patients( 26.1 per cent) had a minor response, 4 patients( 17.4 per cent) stabilization and 2 patients (8.7 per cent) progression. 3. After chemotherapy, 13 patients underwent operation (radical cystectomy 8, partial cystectomy and lymph node dissection 4, transurethral resection of bladder tumor 1) and there were no lymphatic metastasis except only one advanced case. 4. Toxicity included leukopenia in 21 patients and all patients had experienced alopecia, nausea, vomiting and general weakness. It was suggested that neoadjuvant M-VAC chemotherapy may be effective as treatment for patients with invasive bladder carcinoma and we need to define further and extend the potential roles of neoadjuvant chemotherapy for carcinoma.
