Unlabelled: Despite early detection programs, many patients with prostate cancer present with intermediate- or high-risk disease. We prospectively investigated whether (11)C-acetate PET/CT predicts lymph node (LN) metastasis and treatment failure in men for whom radical prostatectomy is planned.

Methods: 107 men with intermediate- or high-risk localized prostate cancer and negative conventional imaging findings underwent PET/CT with (11)C-acetate.

In 19 patients with major depressive disorder, effective treatment with selective serotonin reuptake inhibitors (SSRIs) or amesergide (AMSG) was associated with increased cerebral perfusion in anterior cingulate cortex (SSRI and AMSG) and in medial prefrontal cortex (AMSG). Both selective serotonin reuptake inhibitors and AMSG exert antidepressant action through the serotonin (5-HT) system as reuptake inhibitors. Amesergide differs from SSRIs in that it is also a highly selective 5-HT antagonist, which may in part account for differences in cerebral blood flow response to treatment.

Unlabelled: Patients with rising prostate-specific antigen (PSA) levels after definitive local therapy of prostate carcinoma present a diagnostic dilemma. A local recurrence would be amenable to additional local therapy with curative intent, whereas metastatic disease would require palliative androgen ablation therapy. In this study, we evaluated the effectiveness of PET with (11)C-acetate (AC PET) for evaluation of patients with rising PSA after radical prostatectomy or radiation therapy.

Transmyocardial laser revascularization (TMR) reduces anginal class and is indicated for severely symptomatic patients who are not candidates for conventional revascularization. This report describes a 72-year-old man who presented 4 years following initially successful TMR with recurrent angina refractory to maximal medical management. Reoperative TMR was performed with substantial improvement in angina and functional class.
