Three men, aged 53 to 77 years, had carcinomas of the urinary bladder characterized by foci with a deceptively benign histological appearance. In two cases, this feature led to a significant delay in establishing the correct diagnosis. The diagnostic difficulty in these cases resulted from the resemblance of foci of infiltrating carcinoma to von Brunn's(More)
We report the histological findings seen in the lymph nodes draining the sites of large joint prostheses. Two patients underwent multiple prosthetic joint replacements. In one patient, the regional lymph nodes were enlarged during the revision of a total hip prosthesis, and a representative lymph node was resected. The other patient had undergone a pelvic(More)
Examination of glass slides is of paramount importance in pathology training. Until the introduction of digitized whole slide images that could be accessed through computer networks, the sharing of pathology slides was a major logistic issue in pathology education and practice. With the help of whole slide images, our department has developed several online(More)
The Department of Defense (DOD) has an extensive family of models used to simulate the mission level interaction of weapon systems. Interoperability and reuse of the underlying data files used to create simulation scenarios pose great challenges in this regard. Unlike traditional data integration methods common to federated database research, the emerging(More)
CONTEXT The Q-Tracks program, created in 1999, is a quality monitoring subscription service offered by the College of American Pathologists. OBJECTIVE To establish benchmarks in quality metrics, monitor changes in performance over time, and identify practice characteristics associated with better performance. DESIGN The Q-Tracks program provides ongoing(More)
The Department of Defense (DOD) has an extensive family of models used to digitally simulate the mission level interactions of weapon systems. Interoperability and reuse of the underlying data files used to create simulation scenarios are of particular interest to the modeling community. We develop an architecture to support simulation interoperability by(More)
Professionalism issues are common in residency training and can be very difficult to recognize and manage. Almost one-third of the milestones for pathology recently instituted by the Accreditation Council for Graduate Medical Education encompass aspects of professionalism. Program directors are often unsure of how and when to remediate residents for(More)
CONTEXT The Joint Commission (JC) established new medical staff privileging requirements effective January 2008. The new requirements include the development of ongoing professional practice evaluation (OPPE) and focused professional practice evaluation (FPPE) processes and incorporate the general competencies of patient care, medical knowledge,(More)
