Purpose: To define and evaluate the short-term clinical outcomes of the four-flanged technique for scleral fixation of a dislocated four-eyelet intraocular lens (IOL). Methods: Eleven eyes of 11 patients who underwent scleral fixation of dislocated four-eyelet intraocular lenses using a four-flanged technique were studied retrospectively. We measured the best-corrected visual acuity (BCVA), corneal endothelial cell density, intraocular pressure (IOP), spherical equivalent, astigmatism, IOL tilt and decentration, and postoperative complications. Results: The BCVA was 0.25 ± 0.11 logarithm of the minimal angle of resolution (logMAR) before surgery and 0.14 ± 0.12 logMAR 6 months later (p < 0.001). The corneal endothelial cell count was 2,427 ± 384 and 2,367 ± 298/mm2 before and after surgery, respectively (p = 0.285). The spherical equivalent was 6.02 ± 4.90 and 0.11 ± 0.36 before and after surgery, respectively. There was no significant difference in astigmatism before and after surgery. The mean IOL tilt and decentration were 2.44 ± 1.68° and 0.23 ± 0.09 mm, respectively. The refractive difference was 0.11 ± 0.24 diopters (D). Postoperative complications occurred in one eye; one flange lay outside the scleral tunnel, triggering hyperemia and conjunctival inflammation. Conclusions The four-flanged scleral fixation technique for a dislocated four-eyelet IOL improved the BCVA but did not significantly affect corneal endothelial cell loss. The procedure significantly reduced postoperative IOL tilt, decentration, and astigmatism, and may be a useful alternative to scleral fixation of a dislocated four-eyelet IOL.

To Evaluate the clinical characteristics of childhood-onset systemic lupus erythemoatosus (SLE) and analyse the factors related to outcome of renal function in lupus nephritis, we reviewed medical records of 18 cases of SLF diagnosed at the Department of Pediatrics. Pusan National University Hospital from January 1981 to December 1990. The results were as follow: 1)Male to female ratio was 1:2.6. 2) Nephropathy was the most common initial impression, and 8 cases were diagnosed as SLE at first. 3) The clinical menifestation. was ANA (+), malar rash, renal disorder, hematologic disorder in frequency. 4) Diffuse proliferative lupus nephritis was the most common in renal histopathologic studies. 5) Among the follow-up cases, active lupus was 39%, remission was 28%. 6) As factors related to outcome of lupus nephrits were, hypertension and proteinuria were siginificant statistically.

Purpose of this study was to investigate the biomechanical fates of the partial thickness tear of the rotator cuff in rabbit, and try to provide guideline of treatment for the partial thickness tear of the rotator cuff tendon. Infraspinatus tendons of fifty rabbits were used for study. The rabbits were divided into three groups, twenty for one-third resection(superficial partial resection group), twenty for two-thirds resection(deep partial resection group) and ten for control group. Extraarticular portion of the infraspinatus tendons of the rabbits were resected partially with one-third or two-thirds thickness for each experimental group. We sacrificed five rabbits of each experimental group at 3, 6, 9, and 12 weeks after the resections, and five rabbits for the control group at 6 and 12 weeks. Average maximal load per area of the infraspinatus tendons was measured by tension test. There was significant difference between the deep partial resection group, 5.3 and 6.3 N/emat 6 and 12 weeks respectively, and the control group, 13.2 N/mm(P<0.05). There was no difference between the control and superficial partial resection group, 12.8 and 14.1 N/mm at 6 and 12 weeks, respectively. Shallow partial tears might be healed spontaneously. Deep partial tears would not be healed naturally. When surgical treatment is indicated for deep partial tears of the rotator cuff, tendon repair, rather than debridement, would provide more predictable results.

BACKGROUND: Cardiac tamponade is associated with the expiratory increase and the expira-tory decrease in left ventricular filling flow. With Doppler echocardiography, we analyzed the respiratory variations of mitral and tricuspid inflows, and pulmonary and hepatic venous flows in patients with cardiac tamponade. METHODS: Respiratory hemodynamic changes in mitral and tricuspid inflows and pulmonary and hepatic venous flows were evaluated using Doppler echocardiography in 13 patients (6 men and 7 women; mean age 51+/-13 years) with large pericardial effusion and clinical cardiac tamponade, and compared the results with those of 11 control subjects (3 men and 8 women, mean age 53+/-13 years). Doppler examination was repeated after pericardiocentesis in 6 patients. RESULTS: Peak velocity of early diastolic mitral inflow (E velocity) decreased during inspiration compared with expiratory increase; the mean percentage change was 40%. Peak velocity of late diastolic mitral inflow (A velocity) decreased 13% during inspiration. E/A ratio decreased 31% during inspiration. Deceleration time (DT) and isovolumic relaxation time (IVRT) increased by 26% and 44%, respectively, during inspiration. But respiratory variations of tricuspid inflow were opposite to those of mitral inflow. Tricuspid E velocity increased during inspiration and decre-ased during expiration. The mean percentage change was 123%, which was larger than thte 40% of mitral inflow. The most characteristic findings of pulmonary venous flow during respiration were the expiratory increases of peak diastolic velocity (DV) and diastolic time-velocity integral (D-TVI). The mean percentage changes of peak systolic velocity (SV), DV and D-TVI during respiration were 27%, 45% and 53% respectively. In contrast, the SV and DV of hepatic venous flow increased during inspiration and decreased during expiration. The respiratory variations of peak systolic reverse flow velocity (SR) and peak diastolic reverse flow velocity (DR) were opposite to those of SV and DV. DR notably increased during expiration, and the mean percentage change was 61%. The ratio of RFI (Inspiratory reverse flow integral) to FFI (forward flow integral) of the tamponade group was 270%. The mean percentage changes of each parameters decreased after pericardiocentesis. CONCLUSION: Patients with cardiac tamponade showed inspiratory increases of diastolic tri-cuspid filling flow and hepatic forward flow. Expiratory increases included diastolic mitral filling flow, pulmonary venous systolic and diastolic flow, and hepatic venous reverse flow. Such res-piratory variations decreased after pericardiocentesis.

Syphilis was a common cause of progressive or sudden sensorineural hearing loss. After introduction of penicillin, the incidence of syphilis decreased in general population. However, with the prevalence of HIV infection, it's incidence is increasing. Many studies have substantiated the aggressive and rapidly progressive behavior of neurosyphilis, including otosyphilis, in the presence of HIV infection . We report a case of 38-year-old man HIV infected patient with bilateral sensorineural hearing loss and bilateral total vestibular loss caused by otosyphilis which was resistant to treatment.

The corpus callosum is the main interhemispheric connection in human brain. Agenesis of corpus callosum may partial or complete, and it may have not functional abnormalities. Its prenatal sonographic diagnosis is difficult because of fetal head position, especially in a cephalic presentation. We experienced a case of complete agenesis of corpus callosum. The prenatal sonographic findings was disproportionate dilatation of lateral ventricle, which were suggestive finding of agenesis of corpus callosum or hydrocephalus. We could confirm the diagnosis of complete agenesis of corpus callosum by postnatal MRI.
