Dynamic strategy(DS) is a fast threshold algorithm for the Octopus 101 perimeter. To analyze the efficiency of DS, we compared the results of visual field measurements using DS and conventional normal strategy(NS). Subjects comprised 60 eyes of 30 normal individuals in the 3rd decade who has not experienced perimetry before. Program G2 was performed on all subjects at random and enough intervals between the two tests(more than 1 hour). Mean testing time was 1047.63+/-219.38 seconds in NS and 684.98+/-130.95 seconds in DS. Testing time reduction rate was 32.69+/-14.35% on average. Mean defect(MD) was 2.80+/-1.02dB, 2.15+/-0.94dB in the two strategies, respectively. Corrected loss variance(CLV) was 1.31+/-0.50dB2 and 1.03+/-0.61dB2 in each test. There was significant difference in MD and CLV statistically(P<0.01). Mean short term fluctuation(SF) was 1.38+/-0.49dB and 1.45+/-0.50 dB; mean reliability factor(RF) was 2.05+/-2.73% and 1.98+/-2.80% in the two strategies, respectively. There was no significant difference in SF and RF statistically(P>0.01). It took less time with DS than NS in Octopus 101 perimeter, but further study will be needed for clinical application of DS.

PURPOSE: This study was aimed to evaluate the effect of subconjunctival retention of perfluoropropane gas on the success rates in trabeculectomized rabbits. METHODS: Fifthteen white rabbits were trabeculectomized by fornix-base conjunctival flap, full thickness sclerotomy and iridectomy. The right eye was control and the left eye was injected with 0.2 ml perfluoropropane gas(C3F8) into subconjunctival space through the 30 guage long needle. Each rabbit was examined for bleb morphology under slit-lamp microscope and measured for intraocular pressure by tonopen at preoperative, postoperative 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks. The results were analyzed by Wilcoxon rank sum test in SAS release 6.12 program. RESULTS: Mean gas retention time was 15+/-2 days. Intraocular pressure measured at postoerpative 2 weeks was statistically significantly lower in gas injected group than control group. At postoperative 2 weeks, fibrovascularization was more prominent in control group than gas injected group. Fibroblast proliferation and collagen tissue formation were more prominent in control group than gas injected group at postoperative 6 weeks. CONCLUSIONS: Subconjunctival perfluoropropane gas(C3F8) bubbles, via "spacer" effect, aid the maintenance of filtering blebs in the early postoperative period. This technique may be useful in augmenting or salvaging blebs at high risk of failure.

PURPOSE: The main purpose of this study was to evaluate effects of non-nutritive sucking (NNS) on the oxygen saturation level and behavioral state of preterm infants during tube feeding. METHODS: This study was performed prospectively in the NICU, Chonbuk National University Hopspital from November, 2004 through April, 2005. Preterm infants of gestational age 28 to 37 weeks, who had neither major congenital defects interfering feeding nor respiratory difficulty needing ventilatory support, were included. A total of 64 subjects were divided randomly into the control group (n=32), and the non-nutritive sucking (NNS) group (n=32). The patients in each group were tested for changes in oxygen saturation and behavioral state at 3 different times; 2 minutes before, during, and 2 minutes after feeding. RESULTS: The oxygen saturation of the NNS group increased during feeding and gradually decreased after feeding while the control group decreased during feeding and increased slightly after feeding (P<0.001). During feeding, the "quiet awake" state was observed more frequently in the NNS group and the "crying" state was observed more frequently in the control group. During the post-feeding assessment, the "sleep" state was more frequent in the NNS group and the "crying" state was more frequent in the control group. CONCLUSION: The infants in the NNS group showed significantly higher oxygen saturation level and they were less fussy during tube feeding and slept better after feeding.

BACKGROUND AND OBJECTIVES: Patent ductus arteriosus (PDA) is associated with increased morbidity and mortality in premature infants. Therefore, an early diagnosis and treatment of a hemodynamically significant PDA are very important. A widened pulse pressure is considered to be a well known clinical sign of a PDA in older infants and children; however, whether this is also applicable in the case of preterm infants remains to be confirmed. The aims of this study were to investigate the change in blood pressure (BP) before and after medical treatment of a PDA with indomethacin and to evaluate if the change in the pulse pressure in preterm infants with a medically treated PDA could be used as a reliable clinical predictor of a hemodynamically significant PDA. SUBJECTS AND METHODS: Between January 2005 and June 2009, a retrospective analysis was performed in preterm infants with a hemodynamically significant PDA (PDA group, n=72) and preterm infants without a PDA (control group, n=72) at the Chonnam National University Hospital Neonatal Intensive Care Unit. The PDA was closed by treatment with indomethacin. The BP was compared between the two groups over the seven days after the first dose of indomethacin. RESULTS: In preterm infants with a hemodynamically significant PDA, the mean systolic (55.1+/-6.0 mmHg) and diastolic BPs (31.4+/-6.2 mmHg) were lower than those in the controls (mean systolic BP 58.0+/-6.4 mmHg, mean diastolic BP 34.7+/-6.0 mmHg) before indomethacin treatment. When the ductus arteriosus was successfully closed by indomethacin treatment, there was a gradual increase in both the systolic and diastolic BPs without any change in the pulse pressure. CONCLUSION: The results of this study show that a widened pulse pressure is not a useful clinical sign of a hemodynamically significant PDA in preterm infants. However, low systolic and diastolic BPs may be useful clinical signs of a hemodynamically significant PDA in preterm infants. If the systolic and diastolic BP is low, a PDA should be considered and echocardiography should be performed for early diagnosis and treatment.

PURPOSE: The location of renal cysts is related with the symptoms and signs. Parapelvic cysts are a rare form of simple renal cysts, and they are much more commonly associated with the symptoms of obstruction, pain, infection and stone formation. We evaluated the surgical outcomes of laparoscopic renal cyst marsupialization for treating the peripheral and parapelvic types of renal cysts. MATERIALS AND METHODS: Between November 1993 and April 2007, 87 patients(91 cases) who presented with symptomatic renal cysts underwent laparoscopic renal cyst marsupialization. There were 76 cases in the peripheral cyst group and 15 cases in the parapelvic cyst group. The mean age was 59.2 years(age range: 20-77) for the patients with peripheral renal cysts and 62.9 years(age range: 47-79) for the patients with parapelvic cysts. RESULTS: The mean operative time was 108 minutes(30-280) for the patients with peripheral renal cysts and 144 minutes(80-270) for the patients with parapelvic cysts, and there was a significant difference(p=0.031). However for the other factors, including the time for the first oral intake, the time to remove the drain and the length of the hospital stay, there were no significant differences(p=0.671, 0.088, 0.268, respectively). Complications, including bleeding and leakage, were detected in 11 patients(14.4%) of the peripheral cyst group and in 4 patients(26.6%) of the parapelvic cyst group; there was a statistical difference(p=0.035). Both groups had a high success rate, 98.7% in the peripheral cyst group and 100% in the parapelvic cyst group. CONCLUSIONS: We found that laparoscopic renal cyst marsupialization was a standard treatment with a high success rate and a fast recovery time. However, performing this for parapelvic cysts showed a longer operative time and a higher complication rate as compared with peripheral cysts.

BACKGROUND: There is pressure difference depending on the height of hand position when blood pressure is taken, applying the oscillometric electronic digital BP(blood pressure) monitor. Authors have calculated the degree of BP differences, and evaluated the accuracy and effectiveness of the digital BP monitor comparing with the conventional Mercury Sphygmomanometer. METHOD: Randomized sixty cases consisting of in-patients and hospital workers were subjected for this study. BPs were taken at three different levels-nose level, heart level and knee level-on conventional sitting position applying OMRON Digital Automatic Blood Pressure Monitor and conventional Mercury Sphygmomanometer, and statistical analysis was made. RESULTS: At the nose level, systolic BP and diastolic BP were lower with 23.5mmHg and 18.9mmHg respectively, than at the heart level, while at the knee level, they were higher with 21mmHg and 17.5mmHg respectively, than at the heart level. No actual statistical difference of systolic and diastolic values between OMRON Digital Automatic Blood Pressure Monitoring method at the heart level and conventional Mercury Sphygmomanometeric method. CONCLUSION: Present study demonstrated significant discrepancy of BP values, in systolic and diastolic values, depending on the height of measured finger, when OMRON Digital Automatic Blood Pressure Monitor is applied in taking BP on conventional sitting position. However, no actual discrepancy of BP values was noted between two methods when BP is taken at heart level by OMRON Digital Automatic Blood Pressure Monitor and on brachial artery BP by conventional Mercury Sphygmomanometer. Thus OMRON Digital Automatic Blood Pressure Monitor could take the place of Mercury Sphygmomanometer in taking peripheral BP, which subsequently enable us to estimate central artery BP, which is believed to be better clinical index, through this much more handy electrical oscillometric device in the future.
