Chairside decontamination of endodontic files.

Chairside decontamination. of files and reamers is attempted during root canal treatment. The purpose of this study was to evaluate some techniques for reducing the number of microorganisms of artificially contaminated endodontic files. Endodontic files were artificially contaminated with about 10,000 colony-forming units of either B. subtilis spores or S. mitis. The files containing the bacteria were then subjected to various decontamination procedures. Although sterilization was not achieved with any procedure, the bead sterilizer was found to be the most effective decontamination method tested. All gauze wipings showed reductions greater than 90 per cent. It was concluded that wiping with 2 by 2 inch gauze is a highly efficient and practical method of chairside decontamination

Canal Master files: scanning electron microscopic evaluation of new instruments and their wear with clinical usage.

Canal Master instruments have a short, fluted cutting area and a small flexible shaft; they may be predisposed to rapid wear and breakage. This study examined new and used files as to tip, flute, and shaft design when new and with increasing time of canal preparation. One hundred files prepared 140 curved canals. Sizes #20, #40, and #60 files were examined unused and after 1, 3, 5, and 7 min of use. Evaluation was for uniformity when new and for deterioration and breakage with usage. The smaller sizes (#20 and #40) had some inconsistencies when new and were most predisposed to wear and breakage with time. Findings suggest that smaller files could have had improved quality control by the manufacturer. Also, they should be used with caution and discarded after short times of use in small, curved canals. This should minimize instrument separation and maximize cutting efficiency.

The optimal design of MUMPS global file.

This paper presents the basic consideration of global file design on MUMPS language. The major goal of global design is to reduce the number of disc accesses made over the long-term use of a file. To attain this goal, the procedure for finding the global file which minimizes the average number of disc blocks accessed to obtain a data node is proposed. Furthermore, the total number of blocks in use with file design are demonstrated by simple examples.

Powder data file as a tool for identification of dental gold alloys.

In order to obtain data for a prospective powder data file for dental gold alloys X-ray diffraction photograms of 75 different gold alloys were taken using a Guinier-Hägg camera and CuKalpha1 radiation. Before the X-ray photograms were taken the alloys had been heat treated at 700 degrees C, 800 degrees C or 900 degrees C depending on the solidus temperatures of the alloys. The lattice parameters of the samples were determined from the X-ray photograms. These data were supplemented by a specification of the interplanar spacings of the three strongest lines on the diffraction patterns and also by the relative intensities and Miller indices of these lines. An extensive library of reference films is to be collected and this and other details of the file are discussed. It is not intended that the file be used to identify a particular alloy but merely to identify the type of alloy. Thus it can serve as a guide to facilitate the proper selection of gold alloys within practical clinical dentistry.

Computer printing and filing of microbiology reports. 1. Description of the system.

From March 1974 all reports from this microbiology department have been computer printed and filed. The system was designed to include every medically important microorganism and test. Technicians at the laboratory bench made their results computer-readable using Port-a-punch cards, and specimen details were recorded on paper-tape, allowing the full description of each specimen to appear on the report. A summary form of each microbiology phrase enabled copies of reports to be printed on wide paper with 12 to 18 reports per sheet; such copies, in alphabetical order for one day, and cumulatively for one week were used by staff answering enquiries to the office. This format could also be used for printing allthe reports for one patient. Retrieval of results from the files was easily performed and was useful to medical and laboratory staff and for control-of-infection purposes. The system was written in COBOL and was designed to be as cost-effective as possible without sacrificing accuracy; the cost of a report and its filing was 17-97 pence.

Microfiling and automatic filing of radiographs.

When advantage is taken of the newest qualities of microfilms and copy films and when using their special developers and developing machines, it seems today that the microfilming of radiographs on 35 mm film is successful. Equipment in the price range of 67 000 DM is available. It includes automated filming and developing, but slipping microfilms onto the punch card jackets is semi-automatic. The advantage of the equipment is its low price, its small size compared to the Delcomat system, and thus its smaller filing space need. Also, the automation of filing is possible with this system. The system seems to be quite suitable for at least creating and maintenance of teaching files.

A filing system for transparencies.

A system has been developed to facilitate filing of 2 inches X 2 inches Kodachrome slides. This is coordinated with a diagnostic and therapeutic index that allows for easy retrieval. Compact metal filing cabinets are used, eliminating the need for subsequent rearrangement of slides. The system also provides a method for recall of patients. Preoperative photographs are maintained in plastic folders and checked periodically until the postoperative photographs have been taken.

A patient and family number assignment and chart filing system for family physicians.

The Department of Family Medicine and Practice at the University of Wisconsin-Madison has devised and implemented an alpha-numeric system of identifying patient records together with a system of chart filing based on a variation of terminal digit filing. The system provides each patient with a unique identification number. This permanently assigned number is used as part of the medical record (chart) information, as the basis for assigning an account number, as the basis for determining the storage location of the chart in the record room, and as the basis for a family identification number. The number defines the patient's sex and position within the family, and its permanency ensures a capability for conducting both short- and long-term ambulatory care research in the family context.

Oral diagnostic reporting and synchronized image filing using magneto-optical disks.

An experimental radiologic reporting system has been developed and tested. The rewritable and compact magneto-optical disk (MOD) is applied to storing medical images with oral diagnostic reports of these radiologic images. The disk is 5.25 inches in diameter, has 600 MB memory capacity, is erasable, light and compact. Advantages are simultaneous recording of radiologic images and their oral reports by radiologists, and application to circulation of media inside the hospital as well as to filing of medical images. The MOD has a multimedia function of communication and filing. When medical images are taken and stored, oral interpretation by radiologists can be simultaneously added. Physicians can get information of the images and their reports by oral speech at the same time in front of computer workstation. Furthermore, integration of a voice recognition capability is now being undertaken.

The large data base file structure dilemma.

This paper first presents a brief tutorial on the principal random file organization methods for handling two major applications--Transaction oriented systems and information storage and retrieval systems. It then addresses a particular large data base dilemma, not satisfactorily resolved by any of these methods, and which is currently under active investigation. Two approaches to a solution are described. One is called the hybrid inverted list; the other is based upon an old technique called super-imposed coding. The former has been implemented and has recently been installed in an operational system. Some statistics related to file characteristics in this application are provided, but operational cost and performance statistics are not yet available.

[Logetronic micro-film in radiological diagnosis with an integrated system of filming and filing(author's transl)].

The results of one year's routine use of primary microfilm in a large diagnostic radiological institute is reviewed. Positive views were treated by electronic contrast enhancement in an integrated system of immediate filming and filing. The resulting changes and improvements in running the department are described. This involves a fundamental reorganisation of the department, as well as equipment which is not yet commercially available. The latter had therefore to be improvised and is described. Similar procedures introduced elsewhere are critically evaluated. The advantages of immediate filming are stressed and a comparison with conventional large film filing demonstrates its financial advantages. Logical application of the method results in saving in personnel and material, but implies that the radiologist must be prepared to change to positive films in routine diagnosis. By using microfilm positives with a resolution of 4.0 pairs of lines per mm., the results equal those from large film negatives.

QPL-enabled HTSlib library: accelerating sequence file compression using Intel IAA.

SUMMARY: Sequence analysis workflows require the accessibility of large datasets, which require state-of-the-art compression tools. These compression tools, such as Samtools, often rely on HTSlib as a GZip implementation, but are still limited by throughput on time-intensive compression. QPL-HTSLib offers order of magnitude speedups for the compression and decompression of the SAM and BAM file formats commonly used in genomics workflows at the cost of a slightly larger compressed file, and is a drop-in replacement for HTSlib on Intel systems. AVAILABILITY AND IMPLEMENTATION: QPL-HTSLib is freely available on Github as an open-source software project.
