To verify the accuracy and reproducibility of corneal thickness measurements obtained with Orbscan (Orbtek, Inc., Salt Lake City, USA), the measurements were compared with those taken with an ultrasound pachymeter (Omega Compuscan, Storz). Central corneal thickness was measured by each method in 100 eyes of 50healthy subjects. The averages by the two methods were compared. One examiner took the measurements twice by each method in 20 eyes of 10 subjects, and intraexaminer reproducibility was evaluated. Two examiners measured the thickness in 20 eyes of 10 subjects and interexaminer reproducibility was assessed. The average corneal thickness was 550.27+/-3.56 micrometer in the Orbscan measurements and 526.62+/-3.70 micrometer in the ultrasound pachymetry: There was a statistically significant difference between the two methods. Significant difference was noticed but this showed a constant corresponding correlation with the Orbscan showing a 4.4%lower average. The intraexaminer and interexaminer reproducibility showed high reliability(Guttman split-half point<0.99). The Orbscan pachymetry is a highly reliable method and may be widely used in clinical practice.

We studied the ultrastructural alteration of glomerular anionic sites in 6 patients with minimal change nephrotic syndrome, 5 patients with membranous glomerulonephritis, 4 patients with focal segmental glomerulosclerosis, and 4 patients with IgA nephropathy by staining with polyethyleneimine (PEI) as a cationic probe. The control study was examined by using a nephrectomy specimen of non-glomerular disease which had no proteinuria. This method seems to selectively stain heparan sulphate in the basement membranes and has been widely used to evaluate changes in basement membrane charge in various human diseases as well as in experimental studies. The anionic sites in the lamina rara interna and lamina densa of normal glomerular basement membrane were always less numerous and less regularly distributed than those in the lamina rara externa. Characteristic common findings in these glomeruli showed a marked decrease of glomerular anionic sites in the regions with immune-complex deposits and normal distribution in the regions with focally those being absorbed and newly forming glomerular basement membrane. They were not detected in the gap of the basement membrane and on the area of the detached overlying epithelium using the PEI method. But the foot process fusion of epithelial cells seems not to influence the loss of anionic sites on the glomerular basement membrane.

Pulmonary embolism is a serious complication, which is well known in patients undergoing total hip or total knee arthroplasty or lower extremity fracture surgery. But, there are few literatures concerning pulmonary embolism after upper extremity surgery. Pulmonary embolism after minor upper extremity fracture surgery is extremely rare. We report a case of 66-year-old female patient that developed pulmonary embolism after percutaneous cannulated screw fixation for a greater tubercle fracture of the proximal humerus with literature review.

OBJECTIVES: There have been several studies documenting the changing level of the conus throughout infancy and childhood, but there is only a little detailed study that documents the range of conus positions in a living adult population, especially in Korean, without spinal deformity. METHODS: we made a sequential study of magnetic resonance images of the lumbar spine to determine the variation in position of the conus medullaris in 650 living korean adults population without spinal deformity who checked MRI to identify the cause of low back pain. The study population consisted of patients over the age of 16 years. A T1-weighted, midline, sagittal image was reviewed for identifying the postion of conus. This location was recorded in relation to the upper, middle, or lower third of the adjacent vertebral body or the adjacent intervertebral disc. RESULTS: The study group consisted of 305 men(47%) and 345 women(53%) with a mean age 45.9 years(range, 16-79 years). The conus existed commonly at the middle third of L1(131cases, 20.2%), at the L1-2 intervertebral space(129cases, 19.8%), and the lower third of L1(123cases, 18.9%). The mean position of conus was the lower third of L1(range, middle third of T12 to middle third of L3). Conclusions:The mean position of conus was at the lower third of L1(range, middle third of T12 to middle third of L3). This results was same as that of foreign study. Our results of living korean adult population could allow for safe clinical procedures such as lumbar puncture, spinal anesthesia, and help to explain the differences among observed neurologic injuries from fracture-dislocation at the thoracolumbar junction.

To evaluate the reproducibility in measuring the velocities of perifoveal hyperfluorescent dots, we analyzed fluorescein angiographs of 24 eyes[24 patients]which had central serous retinopathy. Fluorescein angiography was performed with a scanning laser ophthalmoscope[SLO, Rodenstock, Mnchen, Germany]Distances between 5 moving hyperfluorescent dots in a perifoveal capillary were measured at each consecutive frame[interval 1/30 sec]. And then velocities of 5 fluorescent dots were measured with image analysis program by converting the distances to real retinal size using the Littmann's curve in 20 eyes. In the other 4 eyes, the velocities between 5 fluorescent dots of each 2 to 4 capillaries were measured. Perifoveal capillary mean blood flow velocity and standard deviation were 2.08 +/-0.36 mm/sec, and mean coefficient of variation of the velocities measured in a vessel of one patient was 12.58%. However, reliability of the velocities of 2 to 4 capillaries on the 4 eyes was relatively low. In conclusion, the measurement of velocities between perifoveal fluorescent dots with scanning laser ophthalmoscope may be a reproducible method for a perifoveal capillary. However, reliability of measuring velocities was not sufficient enough to use the velocity of one perifoveal capillary as macular blood flow.

BACKGROUND: The goal of this study is to identify the factors that predict mortality in elderly trauma patients. METHOD: We reviewed retrospectively the medical record of 144 cases of geriatric trauma admitted to Kyungpook National University Hospital firm January 1998 to December 1998. We evaluated the general characteristics, mechanisms of injury, Revised Trauma Score(RTS), Injury Severity Score(ISS), Probability of survival(Ps) by TRISS(Trauma and Injury Severity Score) method, amount of blood transfused, preexisting disease, complications, length of stay, and mortality. RESULTS: 1. The mean age was 75.39+/-7.89 years old, and male to female ratio was 0.89 : 1. 2. The mechanisms of injury were primarily frills(56.3%) followed by bicycle or motorcycle(13.9%), and pedestrian injuries(13.2%) and motor vehicle accidents(6.9%). 3. The mean Glasgow Coma Scale(GCS), RTS and ISS ate 13.3+/-3.5, 7.2+/-1.4 and 14.2 +/-11.6 respectively. 4. The actual mortality rate was 18.1% (26/144). But by TRISS method, predicted mortality rate was 9.3%(12.5/144), excess mortality rate was 108% and Z score was 3.99 indicating that actual number of death exceed predicted number of death. 5. Between the survivors and nonsurvivors, the insults were significantly different as follows ; systolic blood pressure(141.9+/-28.3 vs. 116.8+/-48.7 mmHg), GCS(14.3+/-2.0 vs. 9.0 +/-5.1), RTS(7.8+/-0.7 vs 5.4+/-2.3), ISS(11.3+/-5.6 vs 27.2+/-20.2), Ps by TRISS(0.97+/-0.06 vs 0.65+/-0.37), preexisting diseases(50.8 vs 69.8%). CONCLUSION: Geriatric patients are more likely to die after trauma than other age groups. The cause of higher actual mortality rate compared to predicted mortality rate was considered as the higher incidence of delayed death due to sepsis or multiple organ failure. In order to reduce the mortality, even with relatively stable initial vile sign, invasive hemodynamic monitoring and intensive treatment are recommended and also, prevention and treatment of nosocomial infection are very important.

BACKGROUND: The in-hospital 'Utstein style' is international recommended guidelines for reporting outcome data from in-hospital resuscitation events. This study was designed to evaluate the current status of in-hospital cardiopulmonary resuscitation(CPR), and to provide basic data far the unified reporting guideline of resuscitation in Korea. METHODS: The patients who had received CPR in a university hospital were searched during one year period from March 1997. The variables according to the Utstein style were evaluated with review of the medical records. RESULTS: During the period, 428 patients had received CPR. Excluding the patients of out-of-hospital arrest and less than 8 years, 242 were enrolled. Their initial ECG rhythms were 55 of asystole, 148 of pulseless electrical activity, and 39 of ventricular fibrillation, The spontaneous circulation was returned in 118(49%, and 48(20% were maintained more than 24 hours. Twenty-two patients(9%) were discharged with spontaneous respiration. Among the survivors, 17 had the Cerebral Performance Category of 1. CONCLUSION: We recommend the Utstein style to report the outcome of in-hospital CPR.
