PURPOSE: To evaluate the effects of prostaglandin analogues on the corneal thickness of patients with primary open-angle glaucoma (POAG) or normal tension glaucoma (NTG). METHODS: This study included 130 eyes of 65 patients who were diagnosed with POAG or NTG. All patients were divided into two groups; one group received prostaglandin analogues, while the other group received alternative ocular hypotensive eyedrops. Corneal thickness, best corrected visual acuity, and flare in the anterior chamber were measured and compared before treatment and at least 24 months (mean: 27 months) after treatment. RESULTS: The mean decrease in corneal thickness was statistically significant in the group using prostaglandin analogues, but not in the control group. Among the various prostaglandin analogues used, travoprost and latanoprost decreased mean corneal thickness, but bimatoprost had no effect. Best corrected visual acuity, refraction power, and flare in the anterior chamber did not change significantly in either group of patients when ocular hypotensive eyedrops were used. CONCLUSIONS: Prostaglandin analogues lower intraocular pressure and decrease corneal thickness if used over a 24 months.

Forty-Five cases of Shigellosis were treated with Ampicillin, TMP/SMX and Rifampin from April 1980. to November 1980. Of the 18 strains of shigellae, in-vitro sensitivity test was performed against twelve antimicrobial agents. The percentage of resistant strains was 77.8% in Ampicillin and 100% in TMP/SMX. Inhibition zone diameter by Rifampin disc was 8~10mm in all cases and clinical improvement with treatment was noted in nearly all cases, therefore we regarded inhibition zone diameter above 8mm sensitive to Rifampin. In clinical evaluation, the percentage of effectiveness by antibiotics was as follows; Ampicillin-60%, TMP/SMX-70% and Rifampin-93.3%. Rifampin appears to be the best, available drug bacteriologically and clinically for the treatment of Shilgellosis.

OBJECTIVES: To determine the occurrence and antimicrobial resistance of pathogenic vibrios from green mussel, Perna viridis in bacoor bay cavite.

METHODS: Vibrios were isolated using TCBS agar and confirmed using API Identification kit. The relationship between the density of vibrios and environment parameters such as months, harvest sites and other physico-chemical parameters of water was determined. The isolated vibrios were subjected to antibiotic resistance testing to determine the resistance patterns.

RESULTS: Pathogenic vibrios were isolated in all of the 90 mussel samples. Of the 183 vibrio isolates, 75 strains were V. alginolyticus and 53 strains belonged to V. cholerae wherein 18 (34%) of these were V. cholerae serotype O1. Forty nine (49) strains belonged to V. parahaemolyticus and six were V. vulnificus. Using the regression analysis, salinity, water temperature and ph have significant correlation on the density of vibrios (p=0.0309), with regression model, total vibrios = -16990763 + 145858 Salinity + 186808 Temperature + 1037886 pH. In the antimicrobial resistance assay,ampicillin had the highest drug resistance (37.8%) followed by nalidixic acid (10.4%), tetracycline (10.4%) and co-trimoxazole (9.3%).

CONCLUSION: Pathogenic vibrios were isolated in mussel of Bacoor, Cavite and can be predicted using salinity, temperature and pH of the water. Thirty six percent (36%) of Vibrio isolates were resistance to ampicillin.

BACKGROUND: The purpose of this study is to recommend the initial therapeutic regimen for adult patients with acute pyelonephritis (APN) according to the changes of antimicrobial susceptibility patterns of causative microorganisms isolated from patients with APN. METHODS: We reviewed medical charts of 229 APN patients, who had been treated at Korea University Guro Hospital from 1st of January, 1999 to 31st of December, 2001. We investigated the demographic data, clinical findings, durations of hospital treatment, antimicrobial susceptibility patterns of the causative microorganisms and initial antibiotic regimens in patients with APN. RESULTS: In this study, 229 adult patients with APN were classified into simple APN patients (118 patients, 51.5%) and complicated APN patients (111 patients, 48.4%). Mean age of patients with simple APN was 38.2+/-14.1 years old and that of patients with complicated APN was 56.1+/-14.9 years old. Mean age of patients with complicated APN was significantly higher than that of simple APN patients (P<0.0001). Escherichia coli was the most common microorganism both in simple APN (96.7%) group and in complicated APN (90.6%) group. Antimicrobial susceptibility of E. coli was at the low level of ampicillin (31%/20%) and trimethoprim-sulfamethoxazole (42.6%/34.2%) in each group. In contrast, ciprofloxacin (11.5%/22.7%), gentamicin (16.4%/22%) and cefotaxime (0%/8.2%) resistance remained at relatively lower level. In comparison of simple APN with complicated APN, ciprofloxacin and gentamicin resistances were higher in complicted APN group. Average duration of hospitalization (5.9+/-2.3 days/8.2+/-4.6 days) and duration of antibiotic use (12.1+/-3.9 days/15.3+/-10.0 days) were significantly longer in complicated APN. CONCLUSIONS: The results of this study suggests that 3rd cephalosporin, aminoglycoside or quinolone antibiotic would considered as one of the initial therapeutic regimen for patients with simple APN in southwestern Seoul.

PURPOSE: Recently, enterococcus spp. have become one of the most common nosocomial pathogens with increasing rates of multi-drug resistance. However, study on enterococcal urinary tract infections (UTIs) in children is very limited, especially community acquired UTIs. We studied the clinical characteristics of enterococcus spp. in community acquired UTIs and antibiotic resistance within our urban area. METHODS: All children with first episode of community acquired UTIs due to enterococcus spp. and Echerichia coli who were admitted in Pusan National University Children's Hospital between January 2010 and January 2013 were included in our study. We retrospectively reviewed their medical records. RESULTS: During the study period, 201 patients were identified to have first episode of community acquired UTIs. 154 cases were E.coli UTIs (76.6%) and 11 cases were enterococcal UTIs (5.5%) and all enterococcus spp. were Enterococcus feacalis. In enterococcal UTI group, voiding cystourethrogram(VCUG) was performed in 7/11 patients and demonstrated 4 vesicoureteral refluxes (VURs) with renal scar and 3 patients underwent corrective surgery. In E.coli UTI group, VCUG was performed in 121/154 patients and demonstrated 23 VURs and 11 patients underwent corrective surgery. Enterococcal group had significant high rate of underlying urinary abnormalities and surgical corrections compared with E. coli group. All enterococcus spp. were susceptible to ampicillin, vancomycin and linezolid, but all were resistant to tetracycline. They also showed 71.4% resistance to trimethoprim-sulfamethoxazole and 20% resistance to ciprofloxacin. CONCLUSION: Community acquired enterococcal UTIs in children were rare within our urban area. However, they could be indicative of severe underlying urinary tract abnormalities.

A large outbreak of Shigella sonnei gastrointestinal infections occurred at Cheju Island in Korea from May to August 2000. We selected 54 strains which were isolated from the primary treatment failure cases in the outbreak, and characterized the resistance-determining region of the R-plasmid. The 54 strains showed same antimicrobial resistance patterns; resistance against ampicillin, streptomycin, tetracycline, and trimethoprim-sulfamethoxazole. The resistance to ampicillin, streptomycin, and tetracycline were mediated by a conjugable plasmid of about 80 kb size, but the trimethoprim- sulfamethoxazole resistance was not transferred by this plasmid. The R-determining region of the plasmid was cloned and characterized. The 8,384 bp sequences contained resistance genes in the following order:strA, strB, tetR, tetA, and sul1. Fifty four isolates harbored the same sized plasmid and showed same ribotyping patterns, which suggested the clonal spread of S. sonnei in the outbreak.

BACKGROUND: We studied the antibiotic sensitivities to the causative microorganisms of acute simple urinary tract infection for recent 3 years. METHODS: We analyzed 112 microorganisms and their antibiotic sensitivities of the 104 patients who were admitted to or visited the Department of Urology, Catholic University St. Marys Hospital and had more than 10cfu/mL on urine culture from June 1996 to January 1999 retrospectively. RESULTS: The chance of gram negative and positive as causative microorganisms was 72.3% and 27.7% respectively. The most common pathogenic microorganisms were Escherichia coli (67.0%) followed by a-hemolytic streptococci, Entercoccus. In gram negative acute UTI, imipenem, sulperanzone showed relatively higher sensitivity, while cotrimoxazole, ampicillin showed relatively lower sensitivity. In gram positive, vancomycin, penicillin showed relatively higher sensitivity, while ampicillin, imipenem showed relatively lower sensitivity. CONCLUSIONS: We consider that gram negative microorganisms, especially E. coli, is the main cause of acute simple UTI. But, we should be concerned about the increase of gram positive organisms and other gram negative organisms besides E. coli. Regarding to the choice of adequate drug in the treatment of UTI, it is necessary to consider the change of pathologic microorganisms.
