Roach's mathematical equations in predicting pathological stage in men with clinically localized prostate cancer.

AIMS AND BACKGROUND: The therapeutic choice in patients with clinically localized prostate cancer depends on preoperative clinical stage. Diagnostic instruments currently available for such an evaluation--considered separately--have not shown enough efficacy. Roach has recently introduced three simple mathematical equations that--on the basis of prostate-specific antigen and the biopsy Gleason score--are aimed at calculating the definitive pathological stage. We retrospectively analyzed our radical prostatectomy data base to assess the accuracy of the equations in predicting the final stage in patients with clinically localized prostate cancer. METHODS STUDY DESIGN: The study included 173 patients who had undergone radical retropubic prostatectomy at our Institution. Patients were divided into 25 groups, depending on preoperative PSA and the biopsy Gleason score. The risk of extracapsular neoplastic growth, seminal vesicle involvement and lymph node involvement was calculated for each group by means of Roach's equations. On the basis of definitive histological examinations, we compared the expected risk to the observed risk. RESULTS: The observed risk fell within the interval of expected risk in 16 of 17 groups (94%) regarding the evaluation of extracapsular growth, in 15 of 17 (88%) regarding the analysis of seminal vesicle involvement, and in 14 of 17 (82%) regarding the evaluation of lymph node involvement. Therefore, the observed event was in agreement with the expected event in 45 of 51 groups (88%). CONCLUSIONS: The equations represent a practical and effective instrument for preoperative clinical staging in patients with localized prostate cancer. By means of these mathematical formulas, one can assess the correct prognosis and--above all--plan the best therapeutic approach.

[Abdomino-scrotal hydrocele]. / L'idrocele inguino-funicolo-vaginale.

In this paper two cases of abdomino-scrotal hydrocele are described. One of these cases resulted really singular due to its rare dimensions as well as to its secondary renal obstruction. After a careful description of the cases a detailed review of the literature as well as of the etiopathogenetic theories of this rare pathology are reported.

[Atypical presentation of angiomiolypoma in a patient with peritoneal metastases from ovarian cancer: a case report]. / Presentazione atipica di un angiomiolipoma renale in paziente affetta da metastasi peritoneali da adenocarcinoma papillifero ovarico: considerazioni su un caso clinico.

A renal mass with not typical instrumental characteristic in patient in follow-up for ovarian neoplasia sets to the surgeon serious doubts about proper surgical strategy. Achieve of the conservative renal surgery assisted by the intraoperative use of the radiofrequency energy has allowed to preserve the renal function and the diagnosis of unknown angiomyolipoma.

Hyperhidrosis treatment with bornaprine in the acute phase of spinal cord-injured patients.

STUDY DESIGN: Original article. OBJECTIVE: To test the use of bornaprine in the hyperhidrosis treatment in the acute phase of spinal cord-injured patients. SETTING: Patients with acute spinal cord lesions in the Spinal Unit of Pietra Ligure, Savona, Italy. METHOD: In 4 years, 12 patients have been treated, for a maximum period of 75 days, with dosages ranging from 2 to 4 mg day(-1). RESULTS: All of them reported long-lasting subjective benefits, without side effects, even after the interruption of the therapy. CONCLUSION: The bornaprine treatment, at 2 or 4 mg day(-1) dosage, has been effective and safe to contrast hyperhidrosis, in the acute phase of spinal cord-injured patients. This positive experience would require additional trials and a larger number of cases to gain a more solid support.
