Usefulness of prostate-specific antigen density as a diagnostic test of prostate cancer.

To evaluate the diagnostic usefulness of prostate-specific antigen density (PSAD) in prostate cancer (PC) prostate-specific antigen (PSA) concentrations were measured in 175 patients with benign prostatic hypertrophy (BPH) and 50 patients with PC. Patients with BPH were classified according to the presence of complications of the disease: urinary infection or the presence of a bladder catheter. PSAD levels were observed to be greater than 0.

[Treatment of tumor osteopathy in cancer of the prostate].

Some 40% of patients with prostate cancer present with disseminated disease at the time of diagnosis and up to 80% of the total will develop bone dissemination during the disease. The aging of the population and the elevated incidence of prostate cancer (13% of malignancies in males) bring the figure of prostate cancer diagnosed in Europe to 85,000 new cases every year. To begin with, a comment on the overall aspects of bone metastasis from prostate cancer such as incidence, development mechanisms, distribution, prognosis and clinical outcome is made placing special emphasis on the grading and the evaluation of major therapeutical regimes for this kind of patients.

Seminal vesicle abscess: two case reports and a review of the literature.

Two new cases of seminal vesicle abscess diagnosed by computerized tomography and treated with percutaneous drainage are reported. A review of the 8 cases published so far is also presented.

[Prostatic adenocarcinoma presenting as retrovesical cystic formation. Report of a case].

Presentation of one case of prostate adenocarcinoma with a peculiar evolution towards a large cystic formation at the expense of the left prostate lobe, clinically revealed as a picture of poor performance status and impaired consciousness secondary to obstructive renal failure. The benign evolution of the case, even though the patient received no specific therapy, is emphasized.
