[Repeat prostate biopsy in patients with previous negative biopsies].

We retrospectively analyzed the results of 104 patients who underwent a second prostate needle biopsy. Between January 1993 and September 2000, 654 needle biopsies were performed and cancer was found in 239 patients. Among the other 415 patients, 104 patients underwent a second biopsy. The average prostate specific antigen (PSA) value was 9.6 ng/ml (2.0-30.9) (Tandem R conversion value). Cancer was detected in 16 out of 104 cases (15%) at the second biopsy, 4 out of 39 (10%) at the third biopsy, and 3 out of 10 (30%) at the fourth biopsy. The age, PSA value, digital examination, echography, and magnetic resonance imaging (MRI) were not helpful in distinguishing the patients with prostate cancer and atypical histological findings at the previous biopsy were the most important information. Among the 9 patients who showed atypical findings at the previous biopsy, 6 (67%) had cancer.

Laparoscopic adrenalectomy for primary and secondary malignant adrenal tumors.

Laparoscopic adrenalectomy is unanimously recognized as the gold standard for the treatment of adrenal tumors, but it is not indicated for tumors of any size when invasion of the surrounding tissues is clearly detected by preoperative imaging. Although laparoscopic adrenalectomy for metastatic adrenal malignancy is a feasible procedure, in the case of primary adrenal malignancy, it should be done very carefully. When laparoscopic surgery is performed for adrenal tumors >6 cm or for tumors that are considered potentially malignant after preoperative imaging or endocrine studies, the operation should be performed only by a highly skilled laparoscopic surgeon. It is also important to inform the patient and family that the tumors may be malignant and that conversion to open surgery could be necessary. The surgeon must create a sufficiently wide working space, remove the tumor and surrounding fat en bloc, and never grasp the tumor or adrenal tissue. The ultrasonically activated scalpel or ultrasonic endoaspirator should be carefully handled so that it does not touch the tumor surface because this will create a risk of tumor-cell dissemination. It also is essential not to persist unreasonably with laparoscopic procedures but to switch immediately to open surgery when laparoscopic surgery becomes difficult.

Regional differences in incidence rates, outcome predictors and survival of stroke.

The aim of our study was to compare subtype-specific incidence rates, case-fatality rates and outcome predictors in different geographical areas, and decide what drives the variations. Analyzing standardized, prospective stroke registers in the Akita Prefecture, Japan, and in Hungary with catchment areas of more than 1.2 and 1.5 million during the same 18 months, we assumed population and ethnic variations in subtype-specific incidence rates, indicating higher risk of ischemic stroke in Hungary and higher risk of hemorrhagic stroke in Japan. The determinants of 28-day case-fatality rates, at least in part, also varied in different populations. However, survival from stroke was mainly influenced by stroke management.
