The Effectiveness of Psychological Interventions for the Treatment of Erectile Dysfunction: Systematic Review and Meta-Analysis, Including Comparisons to Sildenafil Treatment, Intracavernosal Injection, and Vacuum Devices

THE JOURNAL OF SEXUAL MEDICINE, Issue 11 2008
Tamara Melnik PhD
ABSTRACT Introduction., In contrast to the impressive advances in somatic research of erectile dysfunction (ED), scientific literature shows contradictory reports on the results of psychotherapy for the treatment of ED. Aim., Authors conducted a meta-analysis to evaluate the effectiveness of psychological interventions for the treatment of ED compared to oral drugs, local injection, vacuum devices, or other psychological intervention. Method., Distinct sources of randomized controlled trials (RCTs) were searched: electronic databases (between 1966 and 2007), cross checking of references, and contact with scientific societies. Main Outcome Measures., For dichotomous outcomes the pooled relative risks were calculated and for continuous outcomes mean differences between interventions. Statistical heterogeneity was addressed. Results., Eleven RCTs involving 398 men met the inclusion criteria. Conclusions., There is evidence that group therapy improves ED. Focused sex group therapy showed greater efficacy than control group. Men randomized to receive psychotherapy plus sildenafil showed significant improvement of ED and were less likely than those receiving only sildenafil to drop out. Regarding to the effectiveness of psychological interventions for the treatment of ED compared to local injection and vacuum devices no difference was found. Melnik T, Soares BGO, and Nasello AG.

ORIGINAL RESEARCH,ED PHARMACOTHERAPY: Post-Radical Prostatectomy Pharmacological Penile Rehabilitation: Practice Patterns Among the International Society for Sexual Medicine Practitioners

THE JOURNAL OF SEXUAL MEDICINE, Issue 7 2009
Patrick Teloken MD
ABSTRACT Introduction., Despite the fact that there is minimal evidence-based data supporting it, the concept of pharmacological penile rehabilitation following radical prostatectomy (RP) is receiving great attention. Aim., To define attitudes and practice patterns of clinicians who were members of the International Society for Sexual Medicine (ISSM) and/or its affiliated societies. Methods., Members of the ISSM and its regional affiliates were invited to participate in a web-based survey. Main Outcome Measures., Demographic factors, current practice status, and opinions regarding post-RP erectile dysfunction and penile rehabilitation. The statistical methods used included chi-square, Student's t -tests, and logistic regression analysis. Results., Three hundred-one physicians from 41 countries completed the questionnaire (82% were urologists). Sixty-five percent of the responders had formal sexual medicine specialty training, 44% had uro-oncology specialty training, and 60% performed RPs. Eighty-seven percent performed some form of rehabilitation. As part of the primary rehabilitation strategy, 95% used phosphodiesterase type 5 inhibitors (PDE5), 30% used vacuum device, 75% used intracavernosal injections, and 9.9% used intraurethral prostaglandin. Fifty-four percent commenced rehabilitation immediately/just after urethral catheter removal, and 37% within the first 4 months after RP. Neither the number of years in medical practice, clinician age, nor country/region of practice differed between rehabilitation performers and nonperformers. With regard to the primary reason for avoiding rehabilitation: 50% responded said it is the cost; 25% said the fact that it is not evidence-based; and 25% said they were not familiar with the concept. Performing rehabilitation was positively associated with urologic oncology training (P = 0.03), performing RP (P < 0.001), and seeing over 50 post-RP patients per year (P = 0.011). Conclusions., Among ISSM members post-RP penile rehabilitation is widely practiced, commenced early, and based predominantly on PDE5 inhibitors and intracavernosal injections. Clinicians who perform RP or see over 50 such patients per year are the most likely to perform rehabilitation. Cost represents the most common reason for rehabilitation neglect.

A randomised controlled trial of two instruments for vacuum-assisted delivery (Vacca Re-Usable OmniCup and the Bird anterior and posterior cups) to compare failure rates, safety and use effectiveness

Background:, Most previous trials of vacuum-assisted delivery have been in settings with high rates of instrumental vaginal delivery (8,12%) and high rates of failure to deliver with the intended instrument (20,30%). Over the past 20 years, vacuum-assisted delivery rates at the Port Moresby General Hospital have been 3,4% with failure rates of <3%. Objective:, The objective is to compare the failure rates of two vacuum extractor instruments, the Vacca Re-Usable Omnicup and the Bird Vacuum delivery system (anterior and posterior cups). Setting:, Port Moresby General national referral and teaching Hospital (PMGH), Papua New Guinea. Population:, Two hundred consecutive women requiring assisted delivery, June,December, 2007. Methods:, When a woman required an assisted delivery, she was randomised into either the Vacca Re-Usable Omnicup (Clinical Innovations Inc.) or Bird anterior or posterior metal cup (depending upon the position of the vertex). One hundred women were randomised to each vacuum device. Statistical analysis was on ,an intention-to-treat' basis. Main outcome measures:, The main outcome measure was the successful completion of the delivery with the allocated instrument. Secondary outcomes were maternal trauma (episiotomy and trauma to the maternal genital tract), significant scalp trauma (sub-galeal haemorrhage or serious abrasion) and fetal and neonatal outcomes (Apgar score less than seven at 5 minutes, days spent in the Special Care Nursery and neonatal death). Results:, Failure rates for both Omnicup (2/100) and Bird metal cups (6/100) were not statistically different (RR 1.05, 95% CI 0.99,1.12; P = 0.17). Rates of maternal trauma and fetal scalp trauma were similar in both groups. Conclusion:, Both the Vacca re-useable Omnicup and the Bird metal cups are very effective instruments to achieve successful assisted delivery and equally so. Failures and problems were associated with not applying the vacuum cup to the flexion point on the fetal scalp and the mechanical faults with vacuum equipment devices. [source]

Generation of Equally Sized Particle Plaques Using Solid-Liquid Suspensions

BIOTECHNOLOGY PROGRESS, Issue 3 2006
Tim Herrmann
A device is presented for the generation of equally sized plaques of sensitive particles in a 96-well format. The resulting particle plaques can be used for the measurement of adsorption isotherms and uptake kinetics in protein chromatography or for immobilization reactions. The particle plaques are formed from suspensions with a vacuum device that is designed as a reusable sandwich module. The particles are retained by a mesh while the solvent is removed by the vacuum. As most particles used for protein chromatography are sensitive to mechanical stress and dehydration, the vacuum device is gentle enough to allow the use of these particles, thus eliminating the uncertainty of slurry preparation and pipetting. Apparatus characteristics and preparation procedures are described precisely. The physical intactness of the particles after the preparation procedure is proved by microscopic analysis. Data on the uniformity of the obtained resin plaques with respect to the reproducibility of their adsorption performance is given. Finally, adsorption isothermal and kinetic data of BSA on an ordinary HIC system obtained by high-throughput measurements are shown as an application example. [source]

A vacuum device for penile elongation: fact or fiction?

BJU INTERNATIONAL, Issue 4 2006
MOHAMMAD KAZEM AGHAMIR
OBJECTIVE To assess the efficacy of a vacuum device as a noninvasive method for penile elongation. PATIENTS AND METHODS Between September 2003 and November 2004, 37 sexually active men with a stretched penis length of <10 cm were given vacuum treatment three times a week, for 20 min on each occasion, for 6 months. RESULTS After 6 months, the mean penile length had increased from 7.6 cm to 7.9 cm (no significant difference). The efficacy of vacuum treatment was ,,10%, and the patient satisfaction rate was 30%. There was one case of haematoma of the penis and one of glans numbness, both resolved spontaneously without any intervention. CONCLUSION Vacuum treatment of the penis is not an effective method for penile elongation, but provides psychological satisfaction for some men. [source]
