A rare case of malakoplakia of the uterine cervix and the pelvis occurring in an elderly woman who also had xanthogranulomatous pyelonephritis is described and compared with the 15 reported cases of malakoplakia of the female genital tract.
Revolutionary changes in the computer industry brought about in part by the introduction of personal computers are now reaching into clinical laboratories everywhere. Although the true justification for any computer tool may be an intangible one such as improvement in service, such tools can typically be cost justified by increases in productivity alone. A broad spectrum of applications software useful in the medical laboratory is now available in any scale required to meet the needs of any size of laboratory. Perhaps one of the most dramatic changes in this field in the last several years has been the introduction of small-scale integrated laboratory systems that are true small-scale laboratory information systems. As a result, smaller laboratories can now acquire laboratory information systems appropriately scaled to their workload for a fraction of the cost of the large systems. These small laboratory information systems are typically more easily cost justified than larger ones. Achieving productivity gains using computer tools in the laboratory is a management-intensive process requiring careful analysis and thorough planning. Laboratory managers who eschew computer tools are now an anachronism; extinction of this species is imminent.
An analysis of the intralaboratory economic effects of installation of a dedicated laboratory computer system in a 450-bed acute care general hospital laboratory is presented using data accumulated during an eight-year period. Data collection and analytic conventions used included: (1) an inflation factor derived from the CPI to adjust costs; (2) semilogarithmic plotting; (3) patient procedure counts tallied as the raw count for patient specimens according to the CAP Workload Recording Method; and (4) total workload (including patient standard and control items) recorded according to the CAP WRM. The authors conclude that computerization has produced: (1) a decrease in inflation adjusted labor costs per unit of work; (2) a decrease in inflation adjusted direct cost per unit of work; (3) A decline in the ratio of clerical to technical labor force; and (4) An increase in overall productivity of approximately 7%.

This paper reports a case of angiosarcoma of the terminal ileum in a 66-year-old female. This angiosarcoma developed 8 years after postoperative irradiation for ovarian carcinoma. This case appears to be the sixth case of angiosarcoma arising at the site of therapeutic irradiation thus far reported in the literature. The fact that the angiosarcomas in these cases developed in anatomic sites, which are unusual for angiosarcomas in general, suggests that there is a cause-and-effect relationship between irradiation and angiosarcoma. Apart from the direct carcinogenic effect of irradiation, prolonged stimulation for tissue repair resulting from tissue damage secondary to irradiation-induced vascular changes may also play an etiologic role in the development of angiosarcomas in these cases.
