OBJECTIVETo investigated the anti-inflammatory and antimicrobial effects of anthocyanins extracted from black soybean on the chronic bacterial prostatitis (CBP) rat model.

METHODSThe Sprague-Dawley rats were divided into 4 groups, including control, ciprofloxacin, anthocyanins and anthocyanins with ciprofloxacin groups (n=8 in each group). Then, drip infusion of bacterial suspension (Escherichia coli Z17 O:K:H) into Sprague-Dawley rats was conducted to induce CBP. In 4 weeks, results of prostate tissue, urine culture, and histological analysis on the prostate were analyzed for each group.

RESULTSThe use of ciprofloxacin, anthocyanins, and anthocyanins with ciprofloxacin showed statistically significant decreases in bacterial growth and improvements in the reduction of prostatic inflammation compared with the control group (P<0.05). The anthocyanins with ciprofloxacin group showed a statistically significant decrease in bacterial growth and improvement in prostatic inflammation compared with the ciprofloxacin group (P<0.05).

CONCLUSIONSThese results suggest that anthocyanins may have anti-inflammatory and antimicrobial effects, as well as a synergistic effect with ciprofloxacin. Therefore, we suggest that the combination of anthocyanins and ciprofloxacin may be effective in treating CBP to obtain a higher rate of treatment success.

PURPOSE: Gastric cancer is the third-leading cause of cancer-related death in Korea. As the Korean population is ageing, the number of extremely old patients with this disease is increasing. This study examined the clinicopathological characteristics of gastric cancer in extremely old (over 85 years) patients who received treatment or conservative observations and compared the treatment outcomes according to the treatment modality. MATERIALS AND METHODS: A total of 170 patients over 85 years of age were diagnosed with gastric cancer. Of these, 81 underwent treatment for gastric cancer and 89 received conservative observations. The clinicopathological characteristics of the treatment and conservative groupswere compared. RESULTS: The mean age of the patients was 86.5 years. The conservative group included significantly more patients with older ages, macroscopically advanced cancer and upper-middle located cancer. The overall survival rate of the treatment group was significantly higher than that of the conservative group. The disease-specific mortality rate was significantly lower in the treatment group than in the conservative group. Multivariate analysis revealed the clinical course, alarm sign, and macroscopic classification to be independent prognosis factors. CONCLUSION: By itself, the chronological age should not be used as a strategy to determine whether treatmentwill be administered for gastric cancer. Patients who have early gastric cancer or lower-risk preexisting comorbidities should not be discouraged from treatment, even if they are older than 85 years.

BACKGROUND/AIMS: Adalimumab is effective for both remission induction and the maintenance of Crohn's disease (CD) in Western countries. We evaluated the efficacy of adalim-umab in the conventional step-up treatment approach for CD in Korea. METHODS: We retrospectively reviewed 62 patients with CD who were treated with adalimumab. Their Crohn's disease activity index (CDAI) was measured at weeks 4, 8, and 52. Clinical remission was defined as a CDAI score <150. Induction and maintenance outcomes were analyzed. RESULTS: Forty-one patients (66.1%) achieved a reduction of 70 CDAI points at week 8. Among them, 28 (45.2%) achieved clinical remission at week 8, 20 (32.3%) maintained remission at week 52. The absence of prior anti-tumor necrosis factor (TNF) therapy and Montreal classification L1 at baseline predicted clinical remission at week 8 in the multivariate logistic regression analysis. In the Cox proportional hazards model, the hazard ratio for the secondary loss of response during maintenance therapy after clinical remission induction was significantly higher in patients who showed initial mild CDAI severity or Montreal classification A3. CONCLUSIONS: In our study, anti-TNF therapy-naive and Montreal classification L1 were associated with adalimumab efficacy as induction therapy in CD. Further studies are warranted to determine the prognostic factors for the long-term response after adalimumab therapy.

OBJECTIVE: This study aimed to investigate whether the supplementation of Verbal Fluency: Animal category test (VF) performance can improve the screening ability of Mini-Mental State Examination (MMSE) for mild cognitive impairment (MCI), dementia and their major subtypes. METHODS: Six hundred fifty-five cognitively normal (CN), 366 MCI [282 amnestic MCI (aMCI); 84 non-amnestic MCI (naMCI)] and 494 dementia [346 Alzheimer's disease (AD); and 148 non-Alzheimer's disease dementia (NAD)] individuals living in the community were included (all aged 50 years and older) in the study. RESULTS: The VF-supplemented MMSE (MMSE+VF) score had a significantly better screening ability for MCI, dementia and overall cognitive impairment (MCI plus dementia) than the MMSE raw score alone. MMSE+VF showed a significantly better ability than MMSE for both MCI subtypes, i.e., aMCI and naMCI. In the case of dementia subtypes, MMSE+VF was better than the MMSE alone for NAD screening, but not for AD screening. CONCLUSION: The results support the usefulness of VF-supplementation to improve the screening performance of MMSE for MCI and NAD.

A 7-year-old boy was diagnosed with a recurrent embryonal rhabdomyosarcoma in the retroperitoneum. After resection of the mass, direct end-to-end anastomosis of the ureter was not possible owing to the length of the resected segment. Accordingly, we performed ureteral substitution by using the appendix to repair the ureteral defect.

PURPOSE: We evaluated adult patients with acute epididymitis to identify the frequency of actual sexual contacts and the causative organism, and compared clinical examinations, degrees of manifested symptoms, and radiological test results. MATERIALS AND METHODS: We reviewed the medical records of 65 patients older than 18 years presenting with acute epididymitis who had been treated between 2002 and 2011. Scrotal ultrasonography, urinalysis, and urine culture were performed to diagnose the acute epididymitis. Patients were divided into negative (n=45) and positive (n=20) urine culture groups. Then the latter groups were subdivided into a sexually transmitted organism (STO) culture group (n=13) and a non-STO (n=7) culture group. Data on any history of sexual contact, scrotal pain and tenderness, symptoms of urethritis (discharge, dysuria, urethral burning, or irritation), and lower urinary tract symptoms (dysuria, frequency, and urgency of urination) were obtained from all of the subjects. RESULTS: Patients in the positive urine culture group were significantly younger than those in the other group (p=0.224) and were more likely to have a history of sexual contact at least two weeks prior to onset of epididymitis (p=0.012). They had also a significantly enlarged epididymal head and significantly more severe complaints of pain or tenderness than those of latter group (p=0.348, p=0.288). However, the difference in these measures between the STO and non-STO group was not significant, except in the case of age (p=0.044). CONCLUSIONS: Patients of the positive urine culture group with acute epididymitis were significantly younger and more sexually active than the others. They also had severe pain or tenderness and an enlarged epididymal head. There was a close association between clinical symptoms, a positive urine culture, and ultrasonographic findings.

BACKGROUND/AIMS: While gastric variceal bleeding (GVB) is not as prevalent as esophageal variceal bleeding, it is reportedly more serious, with high failure rates of the initial hemostasis (>30%), and has a worse prognosis than esophageal variceal bleeding. However, there is limited information regarding hemostasis and the prognosis for GVB. The aim of this study was to determine retrospectively the clinical outcomes of GVB in a multicenter study in Korea. METHODS: The data of 1,308 episodes of GVB (males:females=1062:246, age=55.0+/-11.0 years, mean+/-SD) were collected from 24 referral hospital centers in South Korea between March 2003 and December 2008. The rates of initial hemostasis failure, rebleeding, and mortality within 5 days and 6 weeks of the index bleed were evaluated. RESULTS: The initial hemostasis failed in 6.1% of the patients, and this was associated with the Child-Pugh score [odds ratio (OR)=1.619; P<0.001] and the treatment modality: endoscopic variceal ligation, endoscopic variceal obturation, and balloon-occluded retrograde transvenous obliteration vs. endoscopic sclerotherapy, transjugular intrahepatic portosystemic shunt, and balloon tamponade (OR=0.221, P<0.001). Rebleeding developed in 11.5% of the patients, and was significantly associated with Child-Pugh score (OR=1.159, P<0.001) and treatment modality (OR=0.619, P=0.026). The GVB-associated mortality was 10.3%; mortality in these cases was associated with Child-Pugh score (OR=1.795, P<0.001) and the treatment modality for the initial hemostasis (OR=0.467, P=0.001). CONCLUSIONS: The clinical outcome for GVB was better for the present cohort than in previous reports. Initial hemostasis failure, rebleeding, and mortality due to GVB were universally associated with the severity of liver cirrhosis.

PURPOSE: The aim of this study was to investigate the anti-inflammatory effects of a new herbal formula (WSY-1075) in a nonbacterial prostatitis rat model. MATERIALS AND METHODS: Prostatitis was induced in male Wistar rats (n=32) by treatment with 17 beta-estradiol and dihydrotestosterone for 4 weeks. After the induction of prostatitis, the rats were randomly divided into one of four treatment groups: control (n=8), ciprofloxacin (n=8), WSY-1075 (100 mg/kg) (n=8), and WSY-1075 (400 mg/kg) (n=8). After 4 weeks of treatment, the prostatic proinflammatory cytokine (tumor necrosis factor-alpha, interleukin [IL]-6, and IL-8) levels and histological findings were noted. RESULTS: The ciprofloxacin and WSY-1075 treatment groups showed significantly decreased proinflammatory cytokine levels compared with the control group. Histologically, treatment with ciprofloxacin and WSY-1075 significantly suppressed the severity of prostatitis lesions compared with those in the control group. No differences in the proinflammatory cytokine levels or histologic findings were observed with the dose dependent treatment of WSY-1075. CONCLUSIONS: The new herbal formula, WSY-1075, showed effective anti-inflammatory activities in the prostate and may be useful for the clinical treatment of nonbacterial prostatitis. Our findings suggest that WSY-1075 has a beneficial effect on the prevention and treatment of nonbacterial prostatitis.

This study aimed to investigate whether the demographic variable-adjustment and supplementation of Frontal Assessment Battery (FAB) score can improve the screening ability of Mini-Mental State Examination (MMSE) for dementia and its subtypes. Five hundred forty-one non-demented comparison (NC) and 474 dementia (320 Alzheimer's disease [AD]; 139 non-Alzheimer's disease dementia [NAD]; and 15 mixed AD-NAD dementia) individuals living in the community were included. Education-adjusted MMSE (MMSE-edu) score showed significantly better screening accuracy for overall dementia, AD, and NAD than MMSE raw score. FAB-supplemented MMSE (MMSE-FAB) score had significantly better screening ability for NAD, but not for overall dementia and AD, than MMSE raw score alone. Additional supplementation of FAB to MMSE-edu further increased the ability for overall dementia or NAD screening, but not for AD screening. Further education adjustment of MMSE-FAB also improved its ability for overall dementia, AD, and NAD screening. These results strongly support the usefulness of education-adjustment and supplementation of frontal function assessment to improve screening performance of MMSE for dementia and its subtypes, NAD in particular.

OBJECTIVE: The purpose of this study was to differentiate true progression from pseudoprogression of glioblastomas treated with concurrent chemoradiotherapy (CCRT) with temozolomide (TMZ) by using histogram analysis of apparent diffusion coefficient (ADC) and normalized cerebral blood volume (nCBV) maps. MATERIALS AND METHODS: Twenty patients with histopathologically proven glioblastoma who had received CCRT with TMZ underwent perfusion-weighted imaging and diffusion-weighted imaging (b = 0, 1000 sec/mm2). The corresponding nCBV and ADC maps for the newly visible, entirely enhancing lesions were calculated after the completion of CCRT with TMZ. Two observers independently measured the histogram parameters of the nCBV and ADC maps. The histogram parameters between the true progression group (n = 10) and the pseudoprogression group (n = 10) were compared by use of an unpaired Student's t test and subsequent multivariable stepwise logistic regression analysis to determine the best predictors for the differential diagnosis between the two groups. Receiver operating characteristic analysis was employed to determine the best cutoff values for the histogram parameters that proved to be significant predictors for differentiating true progression from pseudoprogression. Intraclass correlation coefficient was used to determine the level of inter-observer reliability for the histogram parameters. RESULTS: The 5th percentile value (C5) of the cumulative ADC histograms was a significant predictor for the differential diagnosis between true progression and pseudoprogression (p = 0.044 for observer 1; p = 0.011 for observer 2). Optimal cutoff values of 892 x 10-6 mm2/sec for observer 1 and 907 x 10-6 mm2/sec for observer 2 could help differentiate between the two groups with a sensitivity of 90% and 80%, respectively, a specificity of 90% and 80%, respectively, and an area under the curve of 0.880 and 0.840, respectively. There was no other significant differentiating parameter on the nCBV histograms. Inter-observer reliability was excellent or good for all histogram parameters (intraclass correlation coefficient range: 0.70-0.99). CONCLUSION: The C5 of the cumulative ADC histogram can be a promising parameter for the differentiation of true progression from pseudoprogression of newly visible, entirely enhancing lesions after CCRT with TMZ for glioblastomas.
