Young children combine sensory cues with learned information in a statistically efficient manner: But task complexity matters.

Human adults are adept at mitigating the influence of sensory uncertainty on task performance by integrating sensory cues with learned prior information, in a Bayes-optimal fashion. Previous research has shown that young children and infants are sensitive to environmental regularities, and that the ability to learn and use such regularities is involved in the development of several cognitive abilities. However, it has also been reported that children younger than 8 do not combine simultaneously available sensory cues in a Bayes-optimal fashion.

Erectile dysfunction and cardiovascular disease.

Erectile dysfunction (ED) is often a comorbid condition commonly associated with cardiovascular disease (CVD). It is important for physicians to understand that the relationship between ED and CVD is not a coincidence but rather a warning signal. The fact that the symptoms of ED normally arise before the symptoms of a cardiovascular event gives physicians the unique opportunity to see the possible future of their patients' cardiovascular health.

Prostaglandin E1 versus sex therapy in the management of psychogenic erectile dysfunction.

The treatment for psychogenic erectile dysfunction has been previously managed by non-medical methods consisting of counseling with a psychiatrist, psychologist or sex therapist. The success rate for treatment with counseling has not been uniformly successful. This paper compares the treatment of psychogenic erectile dysfunction using standard sex therapy and self-injection therapy using low-dose PGE1.

Prostate-specific antigen testing for prostate cancer. Practical interpretation of values.

The mere mention of prostate cancer strikes fear in the hearts of men. Fortunately, prostate-specific antigen (PSA) is now a recognized tumor marker that can indicate but not exclude the presence of this potentially fatal disease. In this article, Drs Randrup and Baum explain the nature of PSA and the practical application of serum PSA determination.

Clinical experience with 180 inflatable penile prostheses.

I present my experience with 180 inflatable penile prostheses inserted in 167 patients with organic sexual impotence of 4 months to 30 years in duration. Mean age was 59.3 years.

Clinical experience with Mentor Alpha I inflatable penile prosthesis. Report on 333 cases.

Penile prostheses are a well-established form of therapy for erectile dysfunction. We report our experience with 333 cases using the Mentor Alpha I inflatable penile prosthesis. With a follow-up period of 15.

Standardization of penile blood flow parameters in normal men using intracavernous prostaglandin E1 and visual sexual stimulation.

The evaluation of vasculogenic impotence by color flow Doppler ultrasound after injection of intracavernous vasoactive agents allows for simultaneous visualization in real time of arterial and venous blood flow. Normal arterial blood flow parameters after prostaglandin E1 injection have yet to be standardized. Our study was initiated to evaluate blood flow parameters in a normal control population after prostaglandin E1 and visual stimulation.

Congenital giant hydronephrosis with unsuspected transitional cell carcinoma.

A case report of a giant congenital hydronephrosis with multiple foci of transitional cell carcinoma is presented.

Condyloma acuminatum in children.

A case of extensive venereal warts in a nine-year-old female patient is presented. Transmission, pathology, and therapy are discussed.

Critical evaluation of 1-stage cystectomy--reducing morbidity and mortality.

Although it is a major surgical effort removal of the bladder can be done with reasonable safety. In our opinion cystectomy and urinary diversion by an ileal conduit can be performed as a conjoined procedure without need for staging to reduce risks. Mortality up to 3 months postoperatively was 3.

Treatment of condylomata acuminata with carbon dioxide laser.

Ten patients with condyloma acuminatum were treated successfully with carbon dioxide laser photocoagulation. There are no side effects, damage to the surrounding tissue is minimal, and, in our experience, the lesions have not recurred. It is particularly useful for lesions which are recalcitrant to other types of therapy.
