Wound infection after elective carotid thrombendarterectomy is extremely uncommon. A review of the literature fails to document a previous case report. A potentially common mechanism for postoperative wound infection in vascular surgical procedures in which prosthetic conduits are not utilized is discussed and emphasized by the presentation of a case report.
Nurse educators, searching for the best use of technology to facilitate the development and administration of tests, are confronted with a wide variety of computerized test development programs from which to choose. This article provides a comparative review of seven commercially available computerized test development programs: A+ Test Manager and Test Taker, AUTOGENT, CATSoftware System, LXR*TEST, MicroCAT, Question Designer for Windows, and Test Construction Set. Criteria for evaluating these programs including ease of use, psychometric properties, security, and system requirements are discussed. Issues associated with the implementation of computerized test development and computerized test administration are considered. It is imperative that nurse educators understand their goals for computerized test development and administration in the context of their own setting before purchasing a program.
The cytogenetic findings in pleuropulmonary blastoma (PPB) have not been widely studied and reported and are of interest in view of the implications that PPB has for additional tumors in the patient and the patient's relatives. Using standard tumor cytogenetic methodology, we investigated three cases of PPB encountered in our institution over a 5-year period. Trisomy 8 was the only karyotypic abnormality in a localized type 2 PPB and was present with other abnormalities in another type 2 PPB and a massive type 3 PPB. Review of the literature yielded three additional karyotyped PPBs; all had trisomy 8 as part of the abnormalities detected. Trisomy 8 appears to be a characteristic of PPB and may be related to the development of PPB and related tumors.
