Virus infection in patients with histiocytic necrotizing lymphadenitis in Taiwan. Detection of Epstein-Barr virus, type I human T-cell lymphotropic virus, and parvovirus B19.
The relationship of Epstein-Barr virus (EBV), type I human T-cell lymphotropic virus (HTLV-I), and parvovirus B19 to histiocytic necrotizing lymphadenitis was studied prospectively in 10 Taiwanese patients using materials obtained by fine-needle aspiration and lymph node biopsy. The presence of EBV was detected by in situ hybridization for EBV-encoded RNA expression. Immunocytochemistry was used to detect virus-encoded protein for EBV and parvovirus B19. ⋯ Expressions of EBV-encoded RNA and Fas ligand were detected in all cases. Expression of EBV-encoded protein was identified in only 1 case. Neither HTLV-I nor parvovirus B19 was detected in any case.

Operating theater blood transaction system. A "virtual" blood transfusion service that brings the blood bank to the operating table.
We describe an operating theater blood transaction system (OTBTS) that is a novel computer software system incorporating electronic crossmatch and the concept of a "self-service" blood banking system in the operating theater. Through this system, the surgeons and the anesthetists can issue blood units for intraoperative transfusion for the patients with a negative antibody screen without the need for a porter service or pneumatic tube system. Since implementation of the OTBTS, the time for obtaining compatible blood for intraoperative transfusion has been reduced from 20 to 30 minutes to around 1 minute. ⋯ The 23% of patients who required extra blood units (i.e., more than originally anticipated) during surgery further benefited from the system. The blood stock reserved for patients undergoing surgery was reduced by 20%. Therefore, the OTBTS is a system that can greatly enhance the efficiency and safety of intraoperative transfusion and can also save workforce resources.

Case ReportsOmental endosalpingiosis with endometrial-type stroma in a woman with extensive hemorrhagic pelvic endometriosis.
A 38-year-old woman with extensive hemorrhagic endometriosis causing back pain, pelvic masses, and hydronephrosis also had a palpable omental mass composed of abundant endometrial-type stroma in which the epithelial component was entirely tubal type glandular cells; the stroma in this area did not bleed. This difference in bleeding behavior supports the concept that patterns of differentiation of heterotopic müllerian tissues may depend in part on the influence of local factors and that endometrial epithelium may produce a local trophic or paracrine factor that is absent in tubal epithelium.
