The ultrasonographic features in 26 cases of blunt testicular trauma were reviewed. Ultrasonography diagnosed correctly in 11 surgically proven cases of testicular rupture. There were three false-positive cases, two with a large scrotal hematocele and one with epididymis rupture. there were no false-negative cases. The sensitivity and specificity of ultrasonographic diagnosis were 100% and 80% respectively. The positive and negative predictive values were 78. 6% and 100% respectively. Therefore, the negative diagnosis by ultrasonography can warrant conservative therapy.

Pelvic fistulas may result from obstetric complications, inflammatory bowel disease, pelvic malignancy, pelvic radiation therapy, pelvic surgery, or other traumatic causes, and their symptoms may be distressing. In our experience, various types of pelvic fistulas are identified after pelvic disease or pelvic surgery. Because of its close proximity, the majority of such fistulas occur in the pelvic cavity and include the vesicovaginal, vesicouterine, vesicoenteric, ureterovaginal, ureteroenteric and enterovaginal type. The purpose of this article is to illustrate the spectrum of imaging features of pelvic fistulas.

PURPOSE: Our purpose in this study is to evaluate the effectiveness of bronchial and nonbronchial systemic arteries for the control of hemoptysis. MATERIALS AND METHODS: Seventy patients with massive or recurrent hemoptysis underwent percutaneous transcatheter embolotherapy between 1991 and 1993. Retrospectively we reviewed 77 cases of bronchial artery embotization and 32 cases of nonbronchial systemic artery embolization in the 70 patients. RESULTS: Immdiate control of hemoptysis was achieved in 33 of 39 patients with massive hemoptysis(84.6%) and 20 of 24 patients with recurrent hemopt ysis(83.3%). In 32 cases, nonbronchial systemic arteries contributed significantly to areas of pathologic pulmonary tissue and frequently were the major arterial supply. CONCLUSION: Bronchial artery embolization is an effective and life saving procedure in non-surgical candidates. Recognition and occlusion of nonbronchial systemic arteries that feed to hypervascular pulmonary lesions is essential for successful percutaneous embolotherapy of hemoptysis.

PURPOSE: The extent of ESWL(Extracorporeal Shock Wave Lithotripsy), a treatment for urinary calculus, shows gradual development and the treatment has become generally known as a noninvasive, safe, and efficacious method. Although the testicular effects are not within the vicinity of shock waves in carrying ESWL as a treatment for urinary calculus, research was initiated to examine effects which shock waves might cause on the testis. MATERIALS AND METHODS: After applying shock waves at intensity 4 for 1,000 times to the testis of Sprague Dawley immature rat, the histopathologic changes within the tissue of testis were observed after 1, 7, 14, 28 days, respectively. RESULTS: In the case of the experimental group having shock waves on the testis, destruction of seminiferous tubules, necrosis, and hemorrhage were found out a%or a day. One week later the atrophy of seminiferous tubules, interstitial fibrosis, and a small portion of chronic inflammatory cell appeared The capillary proliferation near the testis capsule also appeared. Two weeks later somewhat atrophied seminiferous tubules and proliferation of Leydig cells appeared. Diversely atrophied seminiferous tubules, diffusion of Leydig cell proliferation, calcified tubules, and foreignbody reaction were discovered after 4 weeks. As times went on, the tendency of recovery appeared. CONCLUSIONS: Noxious influences such as testicular atrophy and disturbance of spermatogenesis occurred in inflicting immediate shock wave on the testis. Therefore the need of more researches concerning long-term sequelae and the influences on the human body should be taken into consideration.

To assess the correlation between the remaining serum testosterone and bone mineral density(BMD), and to determine the effect of exogenous testosterone on BMD in subjects with male hypogonadism, we evaluated the serum testosterone levels and BMDs of the femur neck, Ward's triangle and the spine(L1-4) in 20 subjects with Klinefelter's syndrome and 7 with hypogonadotropic hypogonadism before and after testosterone replacement. BMDs of the femur neck, Ward's triangle and the spine were below the age-matched normal mean at 77.8%(21/20), 74.1%(20/27) and 88.9%(24/27), respectively. There were significant differences in serum testosterone levels and the spinal BMD between the two groups and the BMD of the spine closely correlated with the serum testosterone level (R = 0.63, p < 0.001). Following a mean 11.8 +/- 4.9 months of testosterone replacement, the BMD at all sites increased significantly and the pretreatment difference in spinal BMD between the two groups disappeared. We conclude that, although testosterone may increases the bone density, it has a site-specific effect of maintaining and increasing the bone mass especially at the spine in male hypogonadism.

8.Control of Astigmatism Following Extracapsular Cataract Extraction with Posterior Chamber Lens Implantation by Selective Suture Cutting.
Journal of the Korean Ophthalmological Society 1989;30(2):203-210
We evaluated the ability of selective suture cutting to reduce postoperative astigmatism due to tight corneo-scleral(C-S) suture in 65 eyes undergone posterior chamber lens implantation. Under operating microscope, two-planned beveled C-S incision was made from 10:00 position to 2:00 position. At the end of operation. C-S wound was sutured at 11:20 position and 12:40 position with 8-0 Vicryl(R), 'X'-shaped suture at 10:40 position. 12-o'clock, and 1:20 position with 10-0 nylon. We cut the C-S suture with 26G disposable needle under slit lamp after local anesthetics(Alkaine(R)) instillation. Keratometric and refractive measurements were obtained before and at selective intervals(group A:4-6 weeks, group B:7-9 weeks, Group C:10-12 weeks) after surgery. Our analysis demonstrated the followings: 1. Remained astigmatism below 1.5 Diopter at 4th week after selective suture cutting were 87.5% in group A, 86.5% in group B, 83.8% in group C. 2. complications due to suture cutting were C-S wonnd disruption(cutting at 5th week after surgery), mild anterior chamber reaction(cutting at 8th week after surgery), and aganinst-the-rule astigmatism(average 1.25D iopter, Group A:18.8%, Group B:13.5%, Group C:16.7%). 3. Selective suture cutting at postoperative 7-9th weeks can correct the postoperative astigmatism.

The authors studied anxiety, using Zung's SelfRating Anxiety Scale (SAS), in the subjects of 3,893 male and 1,976 female college students of Yeungnam University. The authors collected the reports of SAS during the periods from October to November, 1984, and applied ANOVA and ttest on the anxiety scores in order to compare them between various psychosocial factors, and sexes. The results could be summarized as follows: There was significant difference in the mean averages of total anxiety scores between male and female students; male students scored 36.92±7.07, female students scored 39.63±7.51, p<0.001. The anxiety scores relating to the items of sweating, apprehension, restlessness, insomnia, dyspnea were relatively higher in both groups. The anxiety scores in the items of paresthesias, mental disintegration, tremors, faintness, dizziness were lower in both groups. Two hundred and one male students (5.2%) showed seriously high anxiety scores of 50 or higher, while 201 female students (10.2%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but females showed more various symptoms and higher level of anxiety than males. In a comparison between male students in different school grades, freshmen showed the highest level of anxiety scores and as the grades of the students became higher, the levels of anxiety scores were lower. The female students who resided in dormitory or other residences, and whose educational fees were paid by brothers or sisters, showed higher level of anxiety scores. There was s strong tendency toward higher anxiety scores in the students who were dissatisfied with their colleges or departments, and who had pessimistic views of self-image in the past, present, or future, in both groups.
