Hepatic disorders in the acquired immune deficiency syndrome: a clinical and pathological study.

We reviewed the clinical data, hepatic histology, and microbiological features of 21 patients with previously documented acquired immune deficiency syndrome who had liver biopsies. Diagnoses of specific infections were made on liver biopsy in 11/21 patients (57%). Granulomas were found in 10/21 patients (48%) and were most often a manifestation of infection with Mycobacterium avium-intracellulare. Elevated levels of serum alkaline phosphatase and longer duration of diagnosed illness were significantly associated with the presence of granulomatous disease.

Local area networks and the hospital.

Hospital information systems are characterized by their complexity of individual functions, heterogeneity of functions, and dependence upon integration. A distributed computerized information system is well suited to meeting the needs of hospitals. A local area communications network (LACN) removes a major impediment to the use of distributed systems. An advanced microprocessor-based LACN using fiberoptic communications has been developed by the Applied Physics Laboratory of The Johns Hopkins University and has been implemented at the University of California, San Francisco Hospital.

A prototype generalized network technology for hospitals: initial implementation.

A demonstration implementation of a distributed data-processing hospital information system using an intelligent local area communications network (LACN) technology is described. This system is operational at the UCSF Medical Center and integrates four heterogeneous, stand-alone minicomputers. The applications systems are PID/Registration, Outpatient Pharmacy, Clinical Laboratory, and Radiology/Medical Records. Functional autonomy of these systems has been maintained, and no operating system changes have been required. The LACN uses a fiber-optic communications medium and provides extensive communications protocol support within the network, based on the ISO/OSI Model. The architecture is reconfigurable and expandable. This paper describes system architectural issues, the applications environment, and the local area network.
