RESUMO
OBJECTIVE: To evaluate the efficacy of continuous intravesical irrigation with saline plus amikacin as adjuvant therapy and to evaluate the computed tomography (CT) scan in supine and prone positions (CystoCT scan) as an alternative diagnostic and evaluation method of intramural gas in emphysematous cystitis (EC) before and after treatment. METHODS: Consecutive patients with a diagnosis of EC who were hospitalized between March 2006 and January 2011 were investigated. The diagnosis was made by CystoCT scan. Treatment consisted of intravenous antibiotics, control of concomitant diseases, and placement of a 3-way urinary catheter for continuous irrigation of 500 mg of amikacin diluted in 1 l of saline given on days 0, 3, and 7. Treatment was considered successful when there was an absence of gas in the bladder wall, the urine culture was negative, there was clinical improvement, and there was an absence of toxicity. RESULTS: Eleven patients were hospitalized with a diagnosis of EC during the study period. Four were excluded from the study, 2 due to the lack of confirmation of the diagnosis with the CystoCT scan. Treatment was successful in all patients; for 6 (86%) this was achieved in 3 days and for 1 (14%) in 7 days. No toxicity was reported. CONCLUSIONS: Continuous intravesical irrigation with saline plus amikacin as adjuvant treatment of EC is an inexpensive, effective, and safe tool that might help conventional treatment and provide a rapid recovery. The CystoCT scan is an alternative method to diagnose and evaluate intramural gas in EC patients. These findings should be challenged in a randomized, multi-centre, placebo-controlled clinical trial.

BACKGROUND: Several viruses with known oncogenic potential infect prostate tissue, among these are the polyomaviruses BKV, JCV, and SV40; human papillomaviruses (HPVs), and human cytomegalovirus (HCMV) infections. Recently, the Xenotropic Murine Leukemia Virus-related gammaretrovirus (XMRV) was identified in prostate tissue with a high prevalence observed in prostate cancer (PC) patients homozygous for the glutamine variant of the RNASEL protein (462Q/Q). Association studies with the R462Q allele and non-XMRV viruses have not been reported. We assessed associations between prostate cancer, prostate viral infections, and the RNASEL 462Q allele in Mexican cancer patients and controls. METHODS: 130 subjects (55 prostate cancer cases and 75 controls) were enrolled in the study. DNA and RNA isolated from prostate tissues were screened for the presence of viral genomes. Genotyping of the RNASEL R462Q variant was performed by Taqman method. RESULTS: R/R, R/Q, and Q/Q frequencies for R462Q were 0.62, 0.38, and 0.0 for PC cases and 0.69, 0.24, and 0.07 for controls, respectively. HPV sequences were detected in 11 (20.0%) cases and 4 (5.3%) controls. XMRV and HCMV infections were detected in one and six control samples, respectively. The risk of PC was significantly increased (Odds Ratio = 3.98; 95% CI: 1.17-13.56, p = 0.027) by infection of the prostatic tissue with HPV. BKV, JCV, and SV40 sequences were not detected in any of the tissue samples examined. CONCLUSIONS: We report a positive association between PC and HPV infection. The 462Q/Q RNASEL genotype was not represented in our PC cases; thus, its interaction with prostate viral infections and cancer could not be evaluated.

UNLABELLED: SUMMAR OBJECTIVES: To find the detection rate of prostate cancer (PCa) in our population with PSA values between 2.6 and 4 ng/ml. METHODS: We included 33 consecutive patients with a median age of 66 years, that had a Transrectal Ultrasound (TRUS) guided biopsy with PSA between 2.6-4 ng/ml. Patients were divided into 2 groups. Group 1: patients with normal Digital Rectal Examination (DRE) and Group 2: Patients with DRE with asymmetry not definitive of PCa. EXCLUSION CRITERIA: known history of PCa, intraepithelial neoplasia or Positive DRE. Statistical analysis/ Chi square, t-student and Fischer exact test. RESULTS: Twenty eight percent of the patients had positive biopsy for PCa. Fifty six percent were Gleason 6 and 44% Gleason 7. Group 1 had 59%(20) and Group 2 41% (13) in. In Group 1 16% had positive biopsy for PCa vs 46% in group 2 (p 0.04) RR 3.07. CONCLUSIONS: There are traces that the detection rate in our population could be lower in comparison with what has been reported in the literature. DRE is crucial in the initial evaluation; asymmetry could increase 3 fold the risk of having PCa.

BACKGROUND: Prostate Cancer (PCa) is the second most frequent neoplasia in men worldwide. Previous reports suggest that the prevalence of PCa in Hispanic males is lower than in Africans (including communities with African ancestry) and Caucasians, but higher than in Asians. Despite these antecedents, there are few reports of open population screenings for PCa in Latin American communities. This article describes the results of three consecutive screenings in the urban population of Monterrey, Mexico. METHODS: After receiving approval from our University Hospital's Internal Review Board (IRB), the screening was announced by radio, television, and press, and it was addressed to male subjects over 40 years old in general. Subjects who consented to participate were evaluated at the primary care clinics of the University Health Program at UANL, in the Metropolitan area of Monterrey. Blood samples were taken from each subject for prostate specific antigen (PSA) determination; they underwent a digital rectal examination (DRE), and were subsequently interviewed to obtain demographic and urologic data. Based on the PSA (>4.0 ng/ml) and DRE results, subjects were appointed for transrectal biopsy (TRB). RESULTS: A total of 973 subjects were screened. Prostate biopsy was recommended to 125 men based on PSA values and DRE results, but it was performed in only 55 of them. 15 of these biopsied men were diagnosed with PCa, mostly with Gleason scores > or = 7. CONCLUSION: Our results reflect a low prevalence of PCa in general, but a high occurrence of high grade lesions (Gleason > or = 7) among patients that resulted positive for PCa. This observation remarks the importance of the PCa screening programs in our Mexican community and the need for strict follow-up campaigns.

OBJECTIVE: To evaluate sexual satisfaction on women who have experienced sexual intercourse with the same partner on non-circumcised and circumcised states. MATERIAL AND METHODS: A total of 19 women between 19 and 53 y/o, median age 30, in which their sexual partner was programmed for circumcision were included in this study. The survey was a validated version on the Changes on Sexual Functioning Questionnaire (CSFQ). General sexual satisfaction, pain during vaginal penetration, desire, vaginal orgasm, vaginal lubrication, sexual frequency changes in oral and/or anal sexual activities and esthetical perception on circumcised penis were surveyed before the procedure and 2 months after. RESULTS: Changes on Vaginal lubrication during intercourse were significant (p = 0.004), it diminished from 78% to 63%. There were no statistically significant differences on general sexual satisfaction, pain during vaginal penetration, desire, vaginal orgasm. CONCLUSIONS: Circumcision has either negative or positive effect on female's partner perception of sexual satisfaction.
