From January 1986 to December 1991, 87 men who underwent single-layer microscopic vasovasotomy were evaluated and also 61 men were followed postoperatively. There was 90.2 (55/ 61 ) per cent return of sperm and 50.8 (31/61) per cent pregnancy using this technique. A 78.4 (24/ 31 ) per cent pregnancy rate was achieved within 8 months postoperatively. In this study there is no difference between the single-layer microscopic vasovasostomy and other microscopic vasectomy reversal in per cent of postoperatively obtaining normal sperm count and pregnancy. Since the single-layer microscopic vasovasostomy is easier, simpler, and time saving, this technique deserves further evaluation and performance.

PURPOSE: To investigate the risk factors related to the location of visual field defects in normal tension glaucoma. METHODS: Eighty-one eyes diagnosed as normal tension glaucoma in patients with early glaucomatous visual field defects were divided into central visual field defects and peripheral visual field defects. The difference between the 2 groups based on the intra-individual comparison were assessed with several ocular risk factors such as sex, age, hypertension, diabetes mellitus, smoking, laterality, intraocular pressure, central corneal thickness, cup-disc ratio, peripapillary atrophy, mean deviation, pattern standard deviation, best corrected visual acuity, and refractive errors. RESULTS: The incidence of hypertension in the central visual field defects group (60.6%) was higher than in the peripheral visual field defects group (22.9%, p = 0.001). The central corneal thickness in the central group (533.1 +/- 18.2 microm) was thinner than in the peripheral group (545.0 +/- 30.0 microm, p = 0.003). Hypertension was the only risk factors for central visual field defects (p = 0.001). In both the central group and peripheral group, upper visual field defects were more common than lower defects. CONCLUSIONS: Hypertension in patients with normal tension glaucoma was a factor involved in central visual field defects. Additionally, numerous visual field defects were mainly found the superior portion.

There were 105 patients with multiple rib fracture or flail chest who had underwent surgical rib fixation using Judet's strut from Aug. 1989 to Aug. 1995. They were 86 men and 19 women, and the age distribution was from 17 to 77(mean 48+/-12). The most common cause of accident was a traffic accident(81%). The mean number of rib fracture was 5.5 and the distribution of patient were flail chest(72, 64.7%), severe displaced rib Fracture(18, 17.1%), traumatic chest wall deformity(10, 95%) and others(5, 4.7%). The operative mortality was 1 patient(0.96%) and the incidence of postoperative complication were 13 patients(12.3%). The duration of perioperative artificial ventilator therapy was 90.5+/-22.6 hours. Our method allowed shorter duration of an artificial ventilation and decreased a functional sequelae. We find this technique to be better than previously published methods, since it provides better stabilization and immobilization of the ribs and thus obviates the need for artificial ventilation and prevents post-traumatic chest deformity.

The analysis of regional myocardial function is important for the evaluation of myocardial performance. We evaluated whether the motion images of the coronary bifurcation points can be used for computation of the regional deformation and the regional wall stress. In 5 mongrel dogs, 4 to 7 lead markers were implanted adjacent to the bifurcarion points of coronary artery. Left ventricular pressure curve was obtained, and left ventriculography was performed to measure the major and minor axes of the left ventricle. Afterthen, biplane coronary arteriography was performed. The motion images of the lead markers and the corresponding coronary bifurcation points were used as landmarkers for the kinetic analysis of the regional wall deformation and wall stress. The results of the analysis using two kinds of landmarkers were well correlated(P<0.001). Analysis of the diagnosis biplane coronary cineangiograms of each patient group demonstrated that quite difference wave forms between the normally perfused segment and the underperfused segments. In group I there was no coronary arterial narrowings and no regional wall motion abnormalities. Their mean and peak wall thicking were 10.10+/-9.28% and 47.99+/-20.70%. And their peak and mean values of circumferential and longitudinal wall stresses are as follows; 2.70+/-0.74x10(5)dyn/cm2, 2.34+/-0.71x10(5)dyn/cm2, 0.84+/-0.21x10(5)dyn/cm2, 2.34+/-0.71x10(5)dyn/cm2, 0.84+/-0.21x10(5)dyn/cm2 and 0.64+/-0.13x10(5)dyn/cm2. Of 5 male patients having coronary arterial disease with regional wall motion abnotmalities(Group III), 2patients have single vessel disease, 2 paitents have 2 vessel disease. In subgroup b of group III, there was a significant decrease of regional wall thickening(mean and peak value; 0.54+/-9.91%.14.87+/-12.055; P<0.001 vs. group I), and increasing tendency of regional wall stresses. Using biplane coronary cineangiogram, which is routine diagnostic procedure in coronary artery disease, this method can valuate regional myocardial function. And this method can evaluate regional myocardial function. And this method will be especially useful, when serial coronary cineangiograms are needed for serial evaluation of patients, such as before and after percutaneous transluminal coronary angioplasty, coronary arterial bypass graft surgery, etc.

Before and after conducting the health promotion program by group occupational health service during 5 years, we surveyed knowledge, attitude and practice about general health(30 items) and occupational health (30 items) among 25 small and medium scale industry workers (before : 355 workers, after : 279 workers) for evaluation of effectiveness. The scores of knowledge for smoking, drinking, cholesterol, mental stress, management of hypertension, and risks in younger or women workers were significantly increased after conducting group occupational health service. The scorers of attitude for controlling of fatty food consumption and cleaning workplace and bathing for health and that of practice for taking the periodic health examination and choking blood pressure were significantly increased but most of items in attitude and practice didn't be changed after services. According to sex, the scorers of men were significantly increased in knowledge of general health, but there were not significant differences in age, job status and work duration group. In conclusion, through the group occupational health service during 5 years, only the scores of knowledge in general health were increased. It suggested that the effective program which can change workers' attitude and practice for health promotion, should be developed and conducted in small and medium scale industry workers.

PURPOSE: To compare the surgical outcomes of functional equator-considering and Parks' methods in infantile esotropia and partially accommodative esotropia. METHODS: The medical records of 96 patients with infantile esotropia and partially accommodative esotropia who underwent bilateral medial rectus muscle recession by functional equator-considering and Parks' methods were reviewed retrospectively. The surgery success rate at 1 month, 3 months, 6 months and 12 months was compared by the deviation angle measurement. RESULTS: Overall success rates were not statistically different between the 2 groups. Additionally, there were no differences in surgical success rate of functional equator-considering and Parks' methods in infantile esotropia and partially accommodative esotropia. When the patients were divided into 2 groups based on 40 PD, no significant difference in success rate between the 2 groups was observed. When patients were divided into 2 groups based on 22 mm of axial length, there was no statistical difference observed. Postoperative overcorrection was 2 (4%) in the functional equator group and 3 (6.5%) in Parks' method group and postoperative undercorrection was 9 (18%, 19.6%) in each group. The incidence of undercorrection in the Parks' method group was significantly higher in the greater than 22 mm axial length group (7, 35.0%) than in the less than 22 mm group (2, 7.7%) (p = 0.029). CONCLUSIONS: There was no statistically significant difference in surgical success rate between the functional equator and Parks' methods in infantile esotropia and partially accommodative esotropia.
