Technical comparison of Abbott's UroVysion and Biocare's CytoFISH urine fluorescence in situ hybridization (FISH) assays.

Background: This study aims to compare the technical performance of Abbott's UroVysion and Biocare's CytoFISH urine cytology probe panel and position the CytoFISH probe panel as an alternative to UroVysion. The CytoFISH probe panel was developed based on clinically sensitive chromosomes found to be amplified in bladder cancers, as well as a locus-specific probe also seen to be amplified in bladder tumors. After extensive testing comparing CytoFISH to UroVysion, we present here our findings for the two assays.

Liesegang rings developing within intraperitoneal endometriotic implants. A case report.

Liesegang rings are acellular, laminated structures that have been reported to accompany a variety of necrotizing and hemorrhagic tissue processes. Although most frequently seen in the kidneys and synovium, they can be present in other tissues. Liesegang rings are of importance because they are frequently confused by pathologists with helminth ova and nematodes, which they resemble.

Injury of the superficial peroneal nerve.

Peripheral nerve injuries may be caused by traction, friction, or compression. The patient's history is helpful in the differential diagnosis of traumatic injury from other causes of peripheral nerve pathology. The authors present and discuss the case history of a patient with a severe plantarflexion and inversion injury.
