Historical Article[Sperm stains in legal medicine. An historical review of forensic authentication methods].
Furnishing proof of human seminal stains is part of daily forensic work in investigations of sexual crimes. In the last two centuries different methods have been described for confirming putative sperm traces. These methods ranged from identification of the smell and appearance of the stain, to simple chemical reactions such as precipitation of crystals and enzymatic proof of acid phosphatase, which are now enhanced by analytic methods of modern molecular biology. This discourse gives a review of the development of different forensic methods for detection of sperm traces, illustrated with historical case studies.

Urosepsis is defined as sepsis caused by urinary tract infection. This occurs in 25% of all sepsis cases. ⋯ Depending on severity, early reconstitution of adequate oxygen delivery has parallel priority, therefore necessitating intensive care unit treatment within the first hours. Therapy should consist of eliminating the infectious focus, antimicrobial treatment, supportive therapy, and special sepsis therapy.

Review[New techniques in computed tomography. Significance for urology].
Computed tomographic (CT) imaging has become the modality of choice for the assessment of patients with urological malignancies. Recently, multi-slice CT imaging was introduced, providing faster acquisition times and higher resolution leading to improved image quality. Several studies show that thin-slice, high-resolution acquisition strategies lead to an improved accuracy for T-staging, especially of renal cell carcinomas. ⋯ In the USA unenhanced CT imaging has almost replaced conventional urography, as no contrast agent is administered and the examination time is shorter. PET/CT examinations provide information on the morphology and function of tumors in one examination. However, there are only few data available for the assessment of urologic tumors.
