A Papanicolaou (Pap) test result of atypical squamous cells of undetermined significance (ASCUS) presents a clinical challenge. Only 5% to 10% of women with ASCUS harbor serious cervical disease, but more than one third of the high-grade squamous intraepithelial lesions (HSILs) in screening populations are identified from ASCUS Pap test results. ⋯ For women with ASCUS Pap tests, HPV DNA testing of residual specimens collected for routine cervical cytology can help identify those who have underlying HSIL. By testing the specimen collected at initial screening, the majority of high-risk cases can be identified and referred for colposcopy based on a single screening.

Liver transplantation is among the most costly of medical services, yet few studies have addressed the relationship between the resources utilized for this procedure and specific patient characteristics and clinical practices. ⋯ Clinical, economic, and ethical dilemmas in liver transplantation are highlighted by these findings. Recipients who were older, had alcoholic liver disease, or were severely ill were the most expensive to treat; this suggests that organ allocation criteria may affect transplant costs. Clinical practices and resource utilization varied considerably among transplant centers; methods to reduce variation in practice patterns, such as clinical guidelines, might lower costs while maintaining quality of care.
