PURPOSE: To assess the erectile response to intracavernous injection of prostaglandin E1 (PGE 1) or papaverine in the impotence patients with diabetes mellitus (DM), and to determine the factors which would predict good response to either drug. MATERIALS AND METHODS: We injected papaverine (10~60 mg) or PGE1 (10~20 mg) into cavernosal tissues of 305 impotence patients with DM (mean age; 56.1 years). Erectile response was classified into poor, moderate, or good, and was comparatively analyzed according to kinds of vasoactive agents, patients` age, duration of DM and impotence, and treatment modality of DM. RESULTS: The frequency of good response to PGE1 was significantly higher than to papaverine (61.5% vs. 42.8%; p<0.05). However, no association between erectile response and patients` age, duration of impotence and DM, and treatment modality of DM was noted. CONCLUSIONS: Prostaglandin E1 seems to be more effective substance than papaverine for intracavernous injection therapy in impotence patients with DM.

PURPOSE: To evaluate the usefulness of magnetic resonance imaging(MRI) and ultrasonography(US) for thediagnosis of jumper's knee in high school basketball players. MATERIALS AND METHODS: In order to detect clinicalcases of jumper's knee, 40 sites of patellar tendon in 20 knees of ten basketball players were assessed by anevaluation of personal history and physical examination. US and MRI were used for detecting compatible findings ofthis condition ; the diagnostic criteria were hypoechoic focus with focal thickening as seen on US, and increasedsignal intensity with focal thickening as seen on MRI. As an early finding of jumper's knee a new sonographiccriterion of focal hypoechoic focus with or without focal thickening, was also applied. RESULTS: At 19 of 40sites(48%), clinical jumper's knee was diagnosed. For the detection of this condition according to known cliteria,sensitivity and specificity were, respectively, 63% and 100%(US) and 32% and 90%(MRI). Using the new criterion,the sensitivity and specificity of US were 84% and 76%, respectively. CONCLUSION: On the basis of known US andMRI criteria for jumper's knee, the sensitivity and specificity of US were higher than those of MRI. We suggestthat hypoechoic focus without focal thickening oas seen on US, is an early finding of jumper's knee.

Neurological complications occur frequently in patients undergoing liver transplantation. We report a case of multi-ple neurologic complications including central pontine and extrapontine myelinolysis, seizure, and mutism after liver transplantation. Though the cause would be obscure and multifactorial, the hyponatremia with its rapid correction dur-ing operation and the side effects of the immunosuppressant would be the most probable causes in this case.

We analysed a perceiving pain at each step (8 step: traction suture, wound incision, anterior capsulotomy, phacoemulsification, irrigation and aspiration, intraocular lens (IOL) implantation, wound suture, subtenon's injection) of cataract surgery by using visual analogue scale (0-10), prospectively. One hundred cases of cataract surgery were performed from November 1995 to March 1996 at Chonnam national university hospital and topical or retrobulbar anesthesia prior to cataract surgery was applied to each 50 patients. There was no difference of age, sex, running time for surgery, and incision method between topical and retrobulbar anesthesia. Pain scores at phacoemulsi fication. irrigation and aspiration, and subtenon's injection were higher than those at other steps in both types of anesthesia. However, a major range of pain scores at each step except of subtenon's injection was mild (1-3). In topical anesthesia, pain score was higher than retrobulbar anesthesia, but there was no statistically significant difference except a step of subtenon's injection. In conclusion, topical anesthesia might be an adequate anesthetic method for cataract surgery.

PURPOSE: We aimed to know the prevalence of abnormal meniscal signal on MR imaging in asymptomatic soccer players and its radiologic significance. MATERIALS AND METHODS: Using T1 and gradient echo T2* weighted sagittal and coronal MR image, 48 knees in twenty-four full time soccer players were evaluated for the meniscal abnormalities, the status of ligament and existance of joint effusion. Meniscal abnormalities were interpretated using grading system of Lotysch. By using Chi-square method, We analyzed the existance of joint effusion could divide the healing state and healed state of the meniscus. RESULTS: The prevalence of Grade 2 and more and Grade 3 were 42% and 39% of asymptomatic knees. In the 24 knees with meniscus tear, nine of the 14 asymptomatic knee showed effusion while eight of the 10 symptomatic knee did. Of 24 knees with meniscal tear, only eleven knees were related to previous history of major knee trauma. CONCLUSIONS: The prevalence of meniscal abnormalities on MR imaging in asymptomatic soccer players was higher(grade 3:39%) than we expected. The joint effusion was not helpful to divide the healing state and healed state of the meniscus. So we suggest baseline MR imaging in the athletes who have been using the knee vigorously could give decisive information for the interpretation of subsequent MRI that may be performed when the players wounded.

BACKGROUND: To examine the influencing factors on patients' satisfaction in the emergency department(ED) far quality assurance. METHODS: Patients who visited to the ED were prospectively investigated from November 1 to December 31,1997. Authors developed questionnaire to investigate influencing factors on patients' satisfaction.4 Chi-square test and 115-REL 7.0 were applied far statistical analysis. RESULTS: Patients' satisfaction was significantly related to physical environment variables, accessibility variables, kindness of hospital personnel variables, and patient's trust for doctors variables. In path analysis, willingness for revisit was influenced by patients' satisfaction, accessibility, physical environment, patients' trust for doctors in order, and willingness for recommendation was influenced by accessibility, patients' satisfaction, and kindness of hospital personnel in order. CONCLUSIONS : The influencing factors on patients' satisfaction are physical environment, accessibility, kindness of hospital personnel, and patient's trust far doctors. Willingness far revisit and willingness far recommendation are influenced by patients' satisfaction. In spite of some limitations, the results of this study can be used as a baseline information for exploring the influencing factors on patients' satisfaction. Further comprehensive research efforts should be made on the study of patients' satisfaction in the ED.

To evaluate the implication of vascular factor in normal tension glaucoma, authors performed color doppler imaging[CDI] for ophthalmic artery, central retinal artery and posterior ciliary artery in 21 eyes of 12 patients in normal tension glaucoma and 16 eyes of 11 patients in normal control group. We compared peak-systolic velocity[PSV], end-diastolic velocity[EDV], mean velocity[MV], resistance index[RI] and pulsatile index[PI] between the two groups. We evaluate the difference in parameters according to age, sex, systolic and diastolic blood pressure, past history of diabetes and hypertension, cup-disc ratio and visual field change. In normal tension glaucoma group, PSV, EDV and MV of ophthalmic artery and central retinal artery were significantly decreased and pulsatile index was significantly increased compared to those of normal group. Resistance index was also increased in normal tension glaucoma group, but statistically not significant. All parameters of posterior ciliary artery had no significant difference between the two groups. Age was related positively to pulsatile index and resistance index of central retianl artery and diastolic blood pressure was related positively to resistance index of ophthalmic artery. Cup-disc ratio was related negatively to PSV and EDV of ophthalmic artery. Above results imply that blood flow velocity decreased by increasing resistance factor in normal tension glaucoma, therefore local vascular factor might be related to the development of the normal tension glaucoma and affected by age, blood pressure and cup-disc ratio change.

OBJECTIVES: Patients with chronic renal failure have increased hemorrhagic tendency due to an uremic platelet dysfunction and complications from anticoagulants used in hemodialysis. They are also prone to have thrombotic complications in the cerebral vessels, coronary arteries and A-V fistula, due to hypercoagulability from changes in various factors. Recently, deficiencies in plasma protein C and S, which are physiological anticoagulants, have been reported to cause thrombosis. In chronic renal failure, plasma protein C and S activities are known to be decreased. METHODS: In the present study, activities and antigen concentrations of plasma protein C and S, as well as AT-III activities were investigated in three groups; the normal control group, the predialysis group of chronic renal failure patients treated conservatively, and the hemodialysis group. The findings were analyzed for their relationship to hypercoagulability. RESULTS: 1) The activities of plasma protein C, S and antithrombin-III were significantly lower in the predialysis chronic renal failure group as compared to the control. Antithrombin-III concentrations in the hemodialysis group assayed immediately prior to dialysis were significantly lower than those of the control group. But, protein C antigen concentrations in the hemodialysis group assayed immediately prior to dialysis were significantly higher than those of the control group. There was no significant difference between these groups in plasma protein C activities, and plasma protein S activities and antigen concentrations. 2) In the hemodialysis group, antithrombin-III activities, antigen concentration and activities of plasma protein C were significantly higher than after dialysis as compared to those before the dialysis. 3) There were no significant difference in plasma protein C, S and antithrombin-III activities and plasma protein C and S antigen concentrations in hemodialysis patients between with and without thrombosis at arterio-venous fistula site. However, plasma protein C and antithrombin-III activities were significantly lower in those with thrombosis as compared to those of the normal control group. There were no significant difference in plasma protein C and S activities and antigen concentrations in those without thrombosis as compared to those of the normal control group. 4) There were no significant diffrences in plasma protein C, protein S and antithrombin-III activities and antigen concentrations in dialysis patients with and without recombinant erythropoietin treatment. 5) There were no significant correlations between serum creatinine and creatinine clearance, and plasma antithrombin-III, protein C and protein S activities and antigen concentrations in predialysis group. CONCLUSION: These results suggest that the decrease in plasma antithrombin-III, protein C and S could be the factors causing hypercoagulability in chronic renal failure patients, and the decreased activities of these factors may return to normal by dialysis. In the hemodialysis group, there were no significant diffrences in plasma protein C and S and antithrombin-III activities and antigen concentrations between the group which showed clinical thrombosis and the group which did not. However, in those who had thrombosis, plasma protein C and antithrombin-III activities are significantly lower than the control group. Administration of recombinant human erythropoietin does not appear to affect the activities of plasma protein C and S and antithrombin-III. In predialysis chronic renal failure patients, there was no significant relationship between renal function and plasma protein C and S and antithrombin-III.
