Antibiotics were reported to be able to alter bacterial surface properties in subinhibitory concentrations (sub-MICs). The effects of sub-MICs of certain antibiotics on a bacterial surface property such as hemagglutination, as well as on the cell morphology were studied using Streptococcus gordonii and Staphylococcus aureus. The effect of sub-M1Cs of antibiotics on the binding of these bacteria to immobilized fibrinogen were also investigated. The MICs of antibiotics were determined by culturing S. gordonii and S. aureus in media supplemented with serially diluted drug solutions, and one-half the MIC was used as the sub-MIC of the drugs, unless stated otherwise. Sub-MICs of antibiotics did not affect bacterial agglutination of erythrocytes. Microscopic observation of S. gordonii grown at sub-MIC concentration of 0.02 ug/ml of amoxicillin revealed cell enlargement of 1.6 times those grown without the drug. When grown in the sub-MIC amount of 0.08 ug/ml of cefazolin, most S. gordonii cells were enlarged and elongated into rod-shape, resulting in 3 times the size of the cells grown without the antibiotic. The data from the fibrinogen-binding experiments showed that the binding of S. gordonii to immobilized fibrinogen was increased with all the B-lactam drugs tested; the binding of S. aureus to immobilized fibrinogen, on the other hand, was decreased with the same drugs. The results show that low concentrations of certain B-lactam antibiotics are able to cause alterations in cellular morphology of S. gordonii and affect the binding of S. gordonii and S. aureus to immobilized fibrinogen.

After aseptic or septic meningitis, some neurologic complications such as convulsions, delirium, rigidity, cerebral infarctions and cerebral hemorrhage can be developed. The cerebral infarction after meningitis is caused by arterial or venous occlusions. Involvement of small perforating arteries leads to ganglionic infarcts while severe sapsm of major vessels may lead to massive infarctions in the distribution of middle and/or anterior cerebral arteries. Cortical venous and/or dural thrombosis (especially in the superior sagittal sinus) produces typical features, including multiple areas of white matter hemorrhagic infarction. These neurologic complications are common in bacterial meningitis and very rare in aseptic meningitis. We experienced a case of cerebral infarction in MCA/ACA territory and subdural hemorrhage in occipital lobe after aseptic meningitis in 10 month-old-boy. We report a case with a brief review of related literature.

5.Factors Influencing Problem and Pathological Gambling in Participants of Horse Race Gambling.
Journal of Korean Academy of Nursing 2012;42(4):589-598
PURPOSE: The purpose of this study was to examine risk factors for pathological gambling of horse race participants. METHODS: The participants, 508 horse race gamblers, completed the DSM-IV criteria of pathological gambling, Alcohol Use Disorders Identification Test (AUDIT-K) and Symptom Checklist-47-Revision (SCL-47-R). Data were analyzed using t-test, chi2-test, Fisher's exact test, and logistic regression analyses. Behaviors related to horse racing, alcohol abuse, and mental health were analyzed between problem or pathological gamblers compared to recreational gamblers. RESULTS: The prevalence rates of recreational, problem, and pathological gambling were 36.6%, 39.4%, and 24.0%, respectively. Frequency of gambling (> or =4/day), frequency of racetrack visiting (> or =3/month), accompaniment (alone), and mental health (SCL-47-R scores) were all associated with increased risks of problem and pathological gambling. Expenditure on betting (> or =200,000 won/day) and alcohol abuse (AUDIT-K 8-20 scores) group members had higher levels of gambling pathology than recreational gamblers. CONCLUSION: Problem and pathological gambling are highly associated with alcohol abuse and mental health disorders, suggesting that clinicians should carefully evaluate this population.

The extract from Smilax china root has been used as medicinal remedy and reported to retain antimicrobial and antimutagenic acitivities. In this study, a possible presence of antioxidant activity of Smilax china root extract was investigated. Methanol extract (Me) revealed the presence of high 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity (IC50 7.4 microg/ml) and protective property of cell's viability. Further fractionation with various solvent extraction and assay showed high levels of DPPH free radical scavenging activity in the ethyl acetate, butanol and water extracted fractions. In addition, V79-4 cells treated with Me of Smilax china root induced an increase of superoxide dismutase, catalase and glutathione peroxidase activities in a dose-dependent manner between 4-100 microg/ml. These results suggest that the medicinal component of the root of Smilax china extracts also contains antioxidant activity.

PURPOSE: The staging of bladder carcinoma is a major determinant of operative management. CT of bladder carcinoma has been widely used to diagnose external extension (pT3b and over), but tumors confined to the bladder wall (from pT1 to pT3a) are poorly delineated. The authors describe CT findings of the superficial bladder carcinoma (below T1, stage A) in thin section CT with air insufflation technique (air insufflation-CT) to facilitate early detection and to aid correct staging of the superficial bladder carcinoma. MATERIALS AND METHODS: The materials consisted of proved 24 cases (1'9 patients, single tumor: 16 patients, multiple tumors :3 patients) of stage A bladder carcinomas. Air insufflation-CT was performed by the infusion of approximately 200 mL of air into the bladder via a Foley catheter. After the routine pelvic CT, bladder tumors were re-scanned with 1.5 to 5 mm thickness and intervals. RESULTS: The superficial bladder carcinomas were detected as nodular(5 cases, 20.8%), papillary(15 cases, 62.5%), pyramidal(2 cases, 8.3%), and domed(2 cases, 8.3%) forms on air insufflation CT. These tumors were classified into three types according to the size of the tumoral neck:type I(pedundulated polypold tumor:4 cases, 16.6%), type II(polypid tumor with short neck :13 cases, 54.2%), and type Ill(sessile tumor :7 cases, 29. 2%). The mean size(tumoral width x height x base o, neck/stalk) of the tumors was 22 x 20 x 16mm. The average tumoral sizes according to each type of the superficial tumors were type 1:22 x 25 x 6mm, type 11:23 x 22 x 18mm, and type III :18 x 15 x 18mm. The mean width of the type I--II tumoral necks was 15mm. The mean length of the type I tumoral neck(pedicle) was 2.5mm. Papillary fronds of the tumors were seen in 10 cases(41.7%) of 24 superficial tumors. Outer margin of the involved bladder wall was smooth in all cases. CONCLUSION: Thin-sectin CT with air insufflation technique for bladder carcinoma was useful in tumoral demonstration, and characteristics of the superficial bladder carcinomas were small polypold tumors had a short neck mostly and smooth outer wall of the involved bladder wall.

PURPOSE: The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS: The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10degrees of mesial angulation to the center analog. Four types of impression coping were prepared with different combinations of types (transfer, pick-up) and lengths (long, short) of the coping. The impressions were made using vinyl polysiloxane (one step, heavy + light body) with an individual tray, and 10 impressions were made for each group. Eventually, 40 experimental casts were produced. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. The analysis of variance was performed using the SPSS (v 12.0) program (alpha = .05), and the statistical significance was set at P < .05. RESULTS: The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. However, no significant difference was observed with respect to the length of the impression coping. Additionally, no significant difference was observed between the parallel and mesial angulated groups. CONCLUSION: Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. The accuracy of the implant master cast did not differ for different lengths of impression coping of at least 11 mm. Additionally, the accuracy of the implant cast was not different for the parallel and 10degrees mesial angulated groups.

BACKGROUNDS/AIMS: Pancreaticoduodenctomy (PD) is associated with high rates of postoperative morbidity and mortality. Although many studies have shown that early postoperative enteral nutrition improves postoperative outcomes, limited clinical information is available on postoperative early oral feeding (EOF) after PD. The aim of this study was to evaluate the clinical feasibility, safety, and nutritional effects of EOF after PD. METHODS: Clinical outcomes were investigated in 131 patients who underwent PD between 2003 and 2013, including 81 whose oral feeding was commenced within 48 hours (EOF group) and 50 whose oral feeding was commenced after resumption of bowel movements (traditional oral feeding [TOF] group). Postoperative complications, energy intake, and length of stay (LOS) were reviewed. RESULTS: Demographic factors were similar in the two groups. The EOF group had a significantly shorter LOS (25.9+/-8.5 days vs. 32.3+/-16.3 days; p=0.01) than the TOF group. The rates of anastomotic leak (1.2% vs. 16%, p=0.00) and reoperation (3.7% vs. 20%, p=0.01) were significantly lower in the EOF group. In the clinically acute phase from postoperative day 1 to day 5, the mean daily calorie intake (847.0 kcal vs. 745.6 kcal; p=0.04) and mean daily protein intake (42.2 g vs. 31.9 g; p=0.00) in the EOF group were significantly higher than that in the TOF group. CONCLUSIONS: Postoperative EOF is a clinically safe, feasible, and effective method of nutritional support after PD.
