Abstract
OBJECTIVES The aim of this study was to determine the risk factors and clinical characteristics of community-acquired acute pyelonephritis (CA-APN) caused by extended-spectrum β-lactamase (ESBL)-producing organisms. METHODS From March 2010 to February 2011, patients with CA-APN were recruited in 11 hospitals in South Korea. Clinical and microbiological data were collected prospectively, and the ESBLs and multilocus sequence types of the ESBL-producing Escherichia coli were characterized. Comparison between CA-APN caused by ESBL-producing Enterobacteriaceae and those by non-ESBL-producing organisms was performed. RESULTS A total of 566 patients were recruited. Enterobacteriaceae were detected in 526 patients. Forty-six isolates (46/526, 8.7 %) were positive for ESBLs. Clinical and microbiological failure did not differ between the two groups, despite there being fewer patients with ESBL-positive isolates provided with appropriate antibiotics initially (19.6 vs. 93.8 %, p < 0.001). However, the duration of hospitalization was longer in the ESBL group (10.5 vs. 7.0 days, p = 0.012). In a logistic regression model, Charlson score ≥1 point [odds ratio (OR) 3.4, 95 % confidence interval (CI) 1.6-7.0, p = 0.001], antibiotics usage during the previous year (OR 3.1, 95 % CI 1.4-7.2, p = 0.008), and urinary catheterization during the previous month (OR 4.4, 95 % CI 1.1-17.6, p = 0.035) were associated with the risks of CA-APN by ESBL producers. CTX-M-15 (48 %) and CTX-M-14 (38 %) were the most common ESBLs. ST131 was the most common clone (7/24, 29.1 %), which was more frequently resistant to cefepime, fosfomycin, and temocillin. CONCLUSIONS The risk factors for CA-APN by ESBL producers were Charlson score ≥1 point, antibiotics usage during the previous year, and urinary catheterization during the previous month.

Abstract
To survey healthcare-associated Clostridium difficile infection (HA-CDI) in a 900-bed tertiary-care hospital, we prospectively investigated the epidemiology of CDI and distribution of PCR-ribotypes. From February 2009 through January 2010, all patients with HA-CDI were enrolled. Epidemiological information and prescription records for antibiotics were collected. The C. difficile isolates were characterized using reference strains and were tested for antibiotic susceptibility. During the survey, incidence of HA-CDI was 71.6 per 100 000 patient-days. In total, 140 C. difficile isolates were obtained from 166 patients with HA-CDI. The PCR-ribotyping yielded 38 distinct ribotypes. The three most frequently found ribotypes made up 56.4% of all isolates; they comprised 37 isolates (26.4%) of PCR-ribotype 018, 22 (15.7%) of toxin A-negative PCR-ribotype 017, and 20 (14.3%) of PCR-ribotype 001. Clostridium difficile PCR-ribotype 018 was present in all departments throughout the hospital during the 11 months, whereas ribotype 017 and ribotype 001 appeared mostly in the pulmonary department. Hypervirulent C. difficile PCR-ribotype 027 was detected in 1 month on two wards. The incidence of CDI in each department showed a seven-fold difference, which correlated significantly with the amount of prescribed clindamycin (R = 0.783, p 0.013) or moxifloxacin (R = 0.733, p 0.025) in the departments. The rates of resistance of the three commonest ribotypes to clindamycin and moxifloxacin were significantly higher than those of other strains (92.1% versus 38.2% and 89.5% versus 27.3%, respectively). CDI is an important nosocomially acquired infection and this study emphasizes the importance of implementing country-wide surveillance to detect and control CDI in Korea.

Abstract
Research in India is evolving at a rapid pace. Ergo, we need faster approval processes and review timelines. Improvement in the quality of institutional review boards would also contribute to good research practices. Clinical research should be included as a part of the undergraduate medical and pharmacy curriculum, and leading hospitals and practitioners should openly endorse research.

Abstract
Angiomyomas of the oral cavity are rare benign vascular neoplasms. In particular, the congenital form has not been reported before in the English language literature. We present a congenital angiomyoma of the tongue that was found on the posterior middle of the tongue in an infant. On MRI, the mass showed an isointense signal to muscle on the T₁ weighted image and a slightly hyperintense signal on the T₂ weighted image. Immunohistochemically, tumour cells were positive to desmin and smooth muscle actin, but negative to vimentin and S100. The treatment was surgical excision and no recurrence was found during the 26 month follow-up period.

Abstract
OBJECTIVES To analyze the biochemical and survival outcomes after permanent low-dose-rate prostate brachytherapy in a large, consecutive, population-based cohort of patients. METHODS A total of 1006 consecutive implants were performed from July 20, 1998 to October 23, 2003 for men with low-risk and "low-tier" intermediate-risk prostate cancer. The prescribed minimal peripheral dose was 144 Gy, using 0.33 mCi (125)I sources and a preplan technique with a strong posterior-peripheral dose bias. Most patients (65%) had received 6 months of androgen deprivation therapy. Supplemental external beam radiotherapy was not used. The prognostic features, dose metrics, and follow-up data were prospectively collected. Kaplan-Meier and Cox regression analyses were used to assess the factors associated with freedom from biochemical recurrence and survival. RESULTS The median patient age at treatment was 66 years. The median follow-up was 54 months for biochemical outcomes and 66 months for survival. The actuarial freedom from biochemical recurrence rate was 95.6% +/- 1.6% at 5 years and 94.0% +/- 2.2% at 7 years. On multivariate analysis, the pretreatment prostate-specific antigen level (P = .03) and androgen deprivation therapy use (P = .04) were predictive of the freedom from biochemical recurrence. The actuarial rates of distant metastasis and disease-specific death at 5 years were both <1%. The overall survival rate at 5 years was 95.2% +/- 1.4% and was 93.4% +/- 1.8% at 7 years. On multivariate analysis, only age was predictive of overall survival (P = .011). CONCLUSIONS When consistently planned and delivered, low-dose-rate brachytherapy, without supplemental external beam radiotherapy or intraoperative planning, can produce cancer-specific outcomes for men with low- and "low-tier" intermediate-risk prostate cancer at least equal to that produced by dose-escalated external beam radiotherapy or surgical prostatectomy.

Abstract
BACKGROUND There have been numerous advances in the area of assisted reproduction. Among the various reasons of implantation failure, intrauterine lesions play an important role. OBJECTIVE The aim of the present study is to evaluate the role of hysteroscopy prior to any assisted reproductive technique. MATERIALS AND METHODS It is a retrospective study of 292 women who attended our infertility clinic over a period of 18 months, who had a variable number of failed IVF cycles previously. RESULTS Out of the 292 women studied, in 74 women, that is 25%, intrauterine pathology was detected, which when rectified by hysteroscopy, gave a considerable increase in pregnancy rate. CONCLUSION According to this study it can be concluded that evaluating the uterine cavity is an important step before any assisted reproductive procedures.

Abstract
19604 Background: Radiotherapy (RT) patients present for daily treatment over many weeks, often accompanied by friends and family. This represents a unique opportunity for intensive smoking intervention concurrently with RT in both cancer patients and their companions. Methods: Eligible participants included smoking cancer patients scheduled to receive = 3 weeks of RT and their smoking family/friends. All participants received bupropion and 9 individualized behavioral interventions (BI) in the RT clinic with an addiction professional, followed by 9–12 scheduled intensive relapse prevention encounters (in person or by telephone). The primary endpoint was feasibility determined by accrual and program completion. Other endpoints included carbon-monoxide (CO) confirmed and participant-reported tobacco abstinence. During 4 months of enrollment, smoking and basic eligibility data were prospectively collected on consultations seen in clinic. Results: Over 8 months 20 cancer patients and 3 family members were enrolled. Based on our sampling, this represented greater than 40% of eligible smokers seen in clinic. Six cancer patients withdrew, all on or before the third BI. 13 participants completed all 9 BIs while 4 patients completed 7–8 BIs. 11 participants reported compliance with bupropion therapy. One participant discontinued bupropion citing increased depression. No other possible adverse events to bupropion or BI were discovered. At the completion of BI, 16 participants had exhaled CO concentrations < 10ppm and 14 participants self-reported tobacco abstinence. Of the 17 participants completing 7–9 behavioral interventions, the median number of relapse prevention sessions was 4 (range 0–8). With a median follow-up of 5.85 months, the 3-month crude self-reported abstinence rate was 41% (7/17). Conclusions: Tobacco cessation with bupropion and intensive BI for cancer patients and their companions during RT was feasible. A significant number of eligible smokers enrolled and completed BI during RT. However, few participants completed scheduled prevention encounters following RT. No significant financial relationships to disclose.

Abstract
BACKGROUND Glutamate activates the N-methyl-d-aspartate (NMDA) receptors and this receptor is involved in the proliferation and migration of various tumour cells in vitro. However, the relationship between NMDA receptor expression and clinical parameters in cancer patients is unclear. Therefore, NMDA receptor 1 (NMDAR1) expression along with its clinical significance was examined in patients with oral squamous cell carcinoma (OSCC). METHODS Eighty-one tumour specimens from OSCC patients were used to determine the NMDAR1 expression level by immunohistochemical staining. The control was obtained from a matched normal adjacent mucosa. The cases were considered to be positive if reactivity was displayed in >25% of the cells. RESULTS The NMDAR1 reactivity was positive in 50 of 81 cases, while it was negative in the control. NMDAR1 expression was significantly associated with a lymph node metastasis (P = 0.008), the tumour size (P < 0.001), and the cancer stage (P = 0.034). The patients whose tumours expressed NMDAR1 had a significantly poorer survival than the patients who were NMDAR1-negative (log-rank = 6.45, d.f. = 1, P = 0.011). CONCLUSIONS The NMDAR1 overexpression was significantly associated with the prognosis-related factors. Therefore, it might be one of the prognostic markers of OSCC.
