Since many cancers could not be visualized buy ketoconazole cream 15gm fast delivery, and their locations not be exactly predicted cheap 15 gm ketoconazole cream, the phenomenon appeared stochastic: that is, assuming random distribution of prostate cancers, the more biop- sies were done the more likely cancer was to be found. This observation could call into question the necessity for performing TRUS during biopsy at all; indeed, at least one publication suggested that the performance of multiple segmental biopsies in a systematic pattern was more important than the method used to guide the biopsy needle (43). Nevertheless, many authors continue to feel that visualization of the prostate by TRUS during biopsy leads to an increased yield. Several studies have shown that if, in addition to systematic biopsies, foci of ultrasound abnormality are also biopsied, an increased number of carcinomas are detected (44–46). These papers tend not to be controlled for the possibility that the extra biopsies might yield an increased number of prostate cancers simply because they involved a greater number of needle passes (the sto- chastic model) rather than because specific areas were biopsied. But there appears to be evidence that TRUS really can maximize the number of prostate cancers detected. First of all, since most carcinomas appear in the peripheral zone of the prostate, and since the peripheral zone can more accurately be localized with TRUS, using TRUS to biopsy the peripheral zone has led to an increased yield of carcinoma (39). In addition, statisti- cal analysis of the likelihood of finding tumor with any given needle track has found that a sample from a region seen to be abnormal by TRUS is more likely to contain tumor than a sample obtained elsewhere. The use of power Doppler ultrasound to assess the level of local tissue blood flow has shown that biopsies from sites of high blood flow are more likely to contain carcinoma than are biopsies from other sites (47). Newhouse of flow permitted by simultaneous use of Doppler ultrasound and the intravenous infusion of an ultrasound contrast agent has also led to an increased yield (48). In summary, the initial hopes that TRUS-guided biopsy of regions in the prostate that demonstrate focal ultrasound abnormality would be a tech- nique of high sensitivity and specificity and that might permit a small number of biopsies have not been supported; to fail to biopsy systemati- cally the various parts of the prostate leads to an unacceptable number of false-negative biopsy sessions. Nevertheless, TRUS still appears to be useful: its ability to guide systematic biopsies into the peripheral zone and the increase in diagnostic yield if focal abnormalities (especially those demonstrated by flow-sensitive techniques) are biopsied justify its contin- ued use as a biopsy guide. Summary of Evidence: Magnetic resonance imaging (MRI) is the most accu- rate of the imaging techniques in local staging, but its relative expense and persistent false-positive and false-negative rates for locally invasive disease suggest that it should be interpreted along with all additional avail- able data, and reserved for patients in whom other data leave treatment choices ambiguous.

CHAPTER 16 Treating Couples with Sexual Abuse Issues Michele Harway and Ellen Faulk ARIA ELENA (35) AND Jose (37) have been married for 10 years and have two children, Rob (9) and Sylvia (7). Maria Elena is an ele- Mmentary school teacher and Jose is a state government employee in a managerial position. Jose complains that Maria Elena has not enjoyed sex during the entire time they have been married. Maria Elena says she is always busy with her work and the children and sex just is not that important to her. During an early session, Jose admits that lately he has been having problems with pre- mature ejaculation, commenting that before marriage "I could go all night. If you are the therapist who is treating Maria Elena and Jose, what is your initial assessment of the presenting problem?
