The effect of vasectomy on the sexual life of couples.

INTRODUCTION: There are several contraceptive methods to prevent pregnancy, reversible as well as nonreversible ones. The sexual satisfaction of couples is affected by many types of contraceptives used. AIM: The aim of this study was to evaluate prospectively the effect of vasectomy on the sexual life and satisfaction of couples. METHODS: Seventy-six couples took part in this evaluation and filled out respective questionnaires before and after vasectomy. All the questionnaires were evaluated statistically for differences in the respective sexual domain scores. MAIN OUTCOME MEASURES: Standardized questionnaires were used. The International Index of Erectile Function (IIEF) as well as postoperative pain score were completed by men. Female Sexual Function Index (FSFI) was completed by the female partner. For statistical analysis, the T-Square Test was used. RESULTS: The average age of couples, who chose the vasectomy procedure, was 37 years for women and 39 years for men. The contraception method most frequently used prior to the vasectomy was the birth control pill. For the male partner, the IIEF showed no significant change in the respective domains. Out of the 76 couples, 93% of the males and 96% of their female partners would recommend and do vasectomy again. The postoperative pain score was 3.5 on 0-10 scale, and there were no postoperative complications reported. The best improvement of the sexual function was noticed for the female partners. The FSFI showed a significant improvement in the domains desire (P < 0.05), arousal (P < 0.05), orgasm (P < 0.05), lubrication (P < 0.05), and satisfaction (P < 0.05). CONCLUSION: This is the first report to our very best knowledge that showed the positive impact of vasectomy on sexual satisfaction of couples. Vasectomy is a safe operation with minimal complication rates.

Development of a 5'-nuclease real-time PCR assay targeting fliP for the rapid identification of Burkholderia mallei in clinical samples.

BACKGROUND: Burkholderia mallei is a potential biological agent that causes glanders or farcy in solipeds, a disease notifiable to the Office International des Epizooties (OIE). The number of reported outbreaks has increased steadily during the last decade, but diagnosis is hampered by the low bacterial load in infected tissues and excretions. METHODS: We developed a B. mallei-specific 5'-nuclease real-time PCR assay that targets the fliP gene of B. mallei and includes an internal amplification control. Specificity was assessed with 19 B. mallei strains, 27 Burkholderia pseudomallei strains, other Burkholderia strains of 29 species, and clinically relevant non-Burkholderia organisms. RESULTS: Amplification products were observed in all B. mallei strains but in no other bacteria. The linear range of the B. mallei real-time PCR covered concentrations from 240 pg to 70 fg of bacterial DNA/reaction. The detection limit was 60 fg of B. mallei DNA. The clinical applicability of the assay was demonstrated by use of organ samples from diseased horses of a recent outbreak that was reported to the OIE by the United Arab Emirates in 2004. CONCLUSIONS: Compared with conventional PCR, our rapid 5'-nuclease real-time PCR assay for the specific identification of B. mallei has a lower risk of carryover contamination and eliminates the need for post-PCR manipulations. This real-time PCR assay also shortens the turnaround time for results and has the potential for automation.

Antimicrobial susceptibilities of Austrian Francisella tularensis holarctica biovar II strains.

The antibiotic susceptibilities of 50 Francisella tularensis subsp. holarctica biovar II strains isolated from hares and human patients from the eastern part of Austria were examined. Minimum inhibitory concentrations (MICs) of 24 antimicrobial agents were determined using Eteststrade mark on cysteine heart agar plates supplemented with 10% sheep blood. All isolates were sensitive to tetracyclines, aminoglycosides, quinolones, chloramphenicol and rifampicin. Resistance was observed in all isolates against macrolides, penicillins and aztreonam. Bacteria were resistant to cephalosporins and carbapenems, except for 8% of strains investigated that were susceptible or intermediately susceptible. Our in vitro susceptibility data can be applied for the detection and comparison of resistance development and to provide in vitro data for the guidance of therapy.

Uroflow nomogram for male adolescents.

PURPOSE: Uroflowmetry is well established for investigating lower urinary tract symptoms. Current nomograms are based on sample sizes limited to 8 men of the same age. We generated percentile curves for the maximum urinary flow rate (Qmax) in relation to voided volume in male adolescents in a large homogenous healthy group. MATERIALS AND METHODS: A total of 348 males who were 18 years old were investigated, excluding probands with a urological history. Only samples with a voided volume of 150 cc or more were included. One micturition was obtained per proband to determine Qmax, the average urinary flow rate, time to Qmax and volume. Resulting curves were compared with nomograms for children and adults. RESULTS: Average voided volume +/- SD was 262 +/- 91.9 cc (range 151 to 664). Qmax was 28.4 +/- 9.7 cc per second (range 11.4 to 76) with an average urinary flow rate of 18.6 +/- 5.5 cc per second (range 4 to 44), a micturition time of 16.9 +/- 6.8 seconds (range 7 to 48) and a mean time to Qmax of 7.8 +/- 4.1 seconds (range 1 to 25). A total of 341 probands had a Qmax of more than 15 cc per second, while only 7 showed a Qmax of less than 15 cc per second. At up to 350 cc Qmax increased with volume, followed by a plateau phase at 350 to 550 cc and a Qmax decrease at higher volumes. CONCLUSIONS: Voiding volumes in a large homogenous adolescent group demonstrated optimal Qmax at voiding volumes between 350 and 550 cc with a decrease at higher volumes. Therefore, uroflow studies in adolescent males should be interpreted with caution at volumes less than 350 and more than 550 cc.

Development of 5' nuclease real-time PCR assays for the rapid identification of the burkholderia mallei//burkholderia pseudomallei complex.

Burkholderia pseudomallei is the causative agent of melioidosis and was classified as a biologic agent by the Centers for Disease Control and Prevention (Atlanta, GA). Acute melioidosis has a case fatality rate of >40%, and septicemia is fatal in up to 90%. The aim of the study was to design 5'-nuclease real-time PCR assays for the rapid and reliable identification of the B. mallei/B. pseudomallei complex. Real-time PCR assays using TaqMan probes targeting the 16S rDNA and fliC were developed on an ABI Prism 7000 sequence detection system (Applied Biosystems, Foster City, CA). Specificity was assessed with 64 B. pseudomallei, nine B. mallei, 126 other Burkholderia strains of 29 species, and 45 clinically relevant non-Burkholderia organisms. Sensitivity, specificity, and positive and negative predictive value of the assays were 100%. Discrimination between B. pseudomallei and B. mallei, an organism which can be regarded as a clone of B. pseudomallei, could not be achieved. A probit analysis revealed that 7.5 and 52 genome equivalents (GE) of B. pseudomallei could be detected using the fliC and the 16S rDNA assays (P = .05), respectively. In spiked blood samples, the detection limit was approximately 300 and 3.000 GE for fliC and the 16S rDNA, respectively. In conclusion, we recommend the simultaneous use of the 16S rDNA and fliC real-time PCR assays for the rapid and specific identification of the B. mallei/B. pseudomallei complex in positive blood cultures or from suspicious bacterial colonies allowing the early onset of appropriate antibiotic therapy.
