ABSTRACT
It has been noted that the downtime of medical informatics systems is often long. Many systems encounter downtimes of hours or even days, which can have a critical effect on daily operations. Such systems remain especially weak in the areas of database and medical imaging data. The scheme design shows the three-layer architecture of the system: application, database, and storage layers. The application layer uses the DICOM protocol (Digital Imaging and Communication in Medicine) and HTTP (Hyper Text Transport Protocol) with AJAX (Asynchronous JavaScript+XML). The database is designed to decentralize in parallel using cluster technology. Consequently, restoration of the database can be done not only with ease but also with improved retrieval speed. In the storage layer, a network RAID (Redundant Array of Independent Disks) system, it is possible to construct exabyte-scale parallel file systems that exploit storage spread. Development and evaluation of the test-bed has been successful in medical information data backup and recovery in a network environment. This paper presents a schematic design of the new medical informatics system that can be accommodated from a recovery and the dynamic Web application for medical imaging distribution using AJAX.

CASE REPORT: We report three cases of diffuse large B-cell lymphoma of the mandible and a review of the literature. All 3 of our patients had stage I AE disease and had complete remission for more than 2 years after 42-46 Gy of irradiation to the primary tumor with regional lymph nodes and 3 courses of chemotherapy consisting of cyclophosphamide, adriamycin, vincristine, and predonisolone (CHOP). Literature analysis, although biased toward published data, indicated that the 3-year disease-specific survival rates for non-Hodgkin's lymphoma (NHL) of the mandible were 90.5% and 47.6% for stages I and II, respectively. The treatment results for NHL of the mandible may be similar to general primary bone NHL and to other extranodal NHL's. CONCLUSION: Radiotherapy alone is not sufficient for tumor control for stage I+II, disease, and combination chemotherapy may be needed.
