Use of instruments of absolute modernity, with the better price/services ratio, with an important consequence for the cultural aspect and research, represents a stadium of a expanding system to attain different objects: the first informative systems for Pathological Anatomy were set the problem to integrate data and texts to produce the reports and the file, today the technology allows a global management of data, texts, images.
Three characteristics that qualify this plan take on a remarkable scientific interest in the field of the Pathological Anatomy and of the Medical Informatics:
1. Codification of the diagnosis according to the standard SNOMED 3.
To obtain the greatest efficacy from the nomenclature of the medicine, it is necessary a method of codification helped by a Windows based interface and an evolved software will furnish the optimal environment for advanced user and not.
2. Quality controls, flow controls, operational controls through the management of the codified informations; management of epidemical codified data, particularly in oncological field and in post-mortem pathology. The codified data will facilitate the preventive screening management of tumors.
3. Images: unified management of images, texts and data, both with end of diagnostic consultation and for medical didactics.
General notes of the informative system of the department
Managerial specific application: standardized files format (FoxPro/xBase)
Hardware platform: personal computer, local area network (Ethernet)
Operating System: multitasking with graphic interface (Windows)
General characteristics: application with Windows interface, compatible with all the other software products of the above-related net, that can manage
cythological, histological tests and autopsies, up to her complete editing of the report.
Integration or availability of a separate form for the informatics management of all the phases of the screening of prevention of the cancer of the uterine cervix.
Data base management
with a coding system of the evolved diagnoses (SNOMED 3) with effective helps to the input of the data (semi-automatic codify/abbreviations/ mnemonic codes) and in the searches of the codes.
In particular will be possible to manage and interrogate the data base with relatively simple instruments, also external to downright management system and through standard software application (for example FoxPro/xBase).
Report with modifiable lay-out
Management of the personal data with individual code calculated on the furnished data.
Opportunity of identification assisted through magnetic badge and/or with bar code labels.
Management of the pathological precedents of each patient.
Management of the authorizations of access to the files diversified for sector or for qualification.
Opportunity of comparison between the data of the Hospital Service (register acceptance shelters) and the town register (for the screening) through ASCII file transfer.
Opportunity of following integration for the straight connection with protocol to fix for inquiry through individual code/surname-name-date -place of birth.
Opportunity to connect the data of the tests with memorized images in digital format.
The Ethernet protocol is, at the moment, the spreaddest and the most flexible standard of data's communication in networks of personal computers. Network cable should be installed, it may cross the department with deviations for the dispensing devices (hub) to which stations will be connected by coaxial/BNC cables or telephonic/ RJ45 ones in order to realize a local star connection, that permits, in case of breakdown, to isolate the individual stations. In accordance with extension and stations' number that will become operating, some relays could be introduced in network.
On workstations, the Microsoft Windows operating system, is suggested to select in the more complete version Windows NT Workstation or Windows 95 versions. Today Windows represents an excellent instrument for an easily managing interface also by side of little expert users.
For file server, Windows NT Server integrates all Netware functions maintaining the same graphic interface of the workstations. Use of this N.O.S. brings to a drastic reduction of learning's times both for ordinary users and for Netware's operators.
Even if potentially all work stations (WS) will develop whatever operation, strategic position of some WS could affect the use of them: it's necessary a different stations' sizing in relation to the principal use. Minimum level of WS' equipment will be: Microcomputer with central process unity (CPU) Intel Pentium, bus PCI (included controller HD and graphic file card), memory cache 256 KB, memory RAM 32 MB, one printer port (two for WS Laboratory for printing labels and work sheets for printer connection, two RS232, hard disk (HD) 1 GB IDE or SCSI (Small computer System Interface), driver for removable floppy disks 3.5", Ethernet card for network connection with 16 bit AT minimum speed of transfer 10/100 MB/sec, accelerating graphic file card SVGA PCI with resolution 1024x768 lines,16 Ml colors, RAM 2 MB and color monitor 15/17" SVGA (preferably no interlaced) pitch 0.28, standard keyboard with 102 Keys, Microsoft or compatible mouse.
A so structured computer will be indicated like WS Base and it will be operative with Windows NT Workstation or Windows 95. Modifications, additional machineries or particular software will be indicated in the following relation, which is relative to each WS, identified according to the main function.
The computer, which should be used as Netware general services, will have named server. Main point: It is not necessary a particular hardware's brand, but all equipments and accessories should be included in the Hardware Compatibility List of MS Windows NT or however guaranteed compatible. Absence of a driver or of a compatibility will prevent the proper use of personal computers.
Function: it should contain the central file, the common programs' and the data line. It's the most important Personal Computer of network, it should be protected from power supply falls by a UPS and it should be installed in a secluded and isolated environment.
Hardware: 1 PC Pentium, bus PCI, at least 3 slot PCI, cache 512 KB, RAM 64 o128 MB, FD. (3"1/2), network Ethernet adapter PCI (10/100 MB/ sec), graphic card SVGA/1024, color monitor SVGA 15", driver SCSI with two high quality hard disks 2 GB SCSI (to manage in mirroring in order to guarantee data's security); driver for optical disk and removable with at least 640 MB SCSI.
Disks and Ethernet adapters (and if necessary also other accessories not standard) should be included in Hardware Compatibility List of Windows NT.
Group of continuity, 600 Watt, no break.
Software network: operating system Windows NT Server with licenses for at least x connections.
WS doctors' studies:
Function: consultation of all kinds of filed data. Execution scientific searches and external consultations. Station for microscopic images' memorization and didactic material's preparation.

Optical scanner for reading bar codes.
Laser printer 8 ppm or ink-jet color printer.
Software: management of images' memorization, visualization and consultation. Database of images linked to service's data.
WS administrative offices and server for printing:
Function: additing tests' answers and data' codification, reports' printing, flux's control on tests in exit, production of services' summarizing tables. Station for backup on tape.
Hardware: WS base; optical scanner for reading bar codes. High velocity of laser printer (at least 10 ppm, 300x300 dpi), RAM 2 MB. Printers should be formatted as network printers on not dedicated server: possible re-configurations could be valued afterward. In one station 1 streaming tape (unity to tape for backup) with at least 1 GB, with interface SCSI included.
Software: office automation's programs, Word for Windows (Microsoft), Excel for Windows (Microsoft). Backup management for Windows NT.
WS lab macro/withdrawals:
