Clinical Trial
Accuracy of the initial history and physical examination to establish the etiology of erectile dysfunction.
Because of its implications for possible therapy, the ability to establish a diagnosis of erectile dysfunction (ED) solely on the basis of history and physical examination has been a matter of controversy. The determination of the etiology of ED based on history and physical examination is evaluated in this present study. ⋯ A multifaceted comprehensive approach is required to evaluate fully and to diagnose ED.

Comparative Study
Radiation therapy for T1 and T2 prostate cancer: prostate-specific antigen and disease outcome.
To evaluate disease outcome using serum prostate-specific antigen (PSA) as an outcome measure in patients with T1 or T2 prostate cancer treated with radiation therapy in the PSA era. ⋯ Radiation therapy is an acceptable modality for treating T1 or T2 disease and produces results comparable to those following radical prostatectomy when patients are stratified according to their pretreatment PSA value. The rapid PSA doubling times observed in patients with relapsing disease are more consistent with a "selective" rather than an "aggravation" mechanism.
