A survey of the use of micro-computers in general dental practice in Scotland.

The aim of the study was to determine current and future use of micro-computers in general dental practice. A piloted questionnaire was sent to 736 general dental practitioners in Scotland, with the intention of contacting one principal from every dental practice known to the Scottish Dental Estimates Board. A total of 390 (53%) of the questionnaires were returned. If it is assumed that those dentists who did not reply have a low interest in computers then the results of the survey are not likely to lead to an overestimation of trends. Six per cent of the 736 practices that were contacted are using a micro-computer, mainly for practice management and particularly for word processing. In addition, 25% of the replies showed some interest in introducing micro-computers in the future. Thirty-four per cent of current users and 19% of prospective users indicated a high degree of interest in direct data transmission between the practice and the Scottish Dental Estimates Board.

Apple II computer software for DNA and protein sequence data.

In our attempt to make the aid of a computer for the molecular biology laboratory available on a low-cost basis, we have improved the programs that we published recently. We have experienced in our laboratory, and have learned from others, that the average lab has an increasing demand to use a time-sharing-independent computer for the bulk of data handling. A microcomputer can give this independence. At the same time, a microcomputer can serve as a terminal for the few computer jobs, such as data communication or extensive search programs, which have to be conducted on a time-sharing basis. In this paper, we describe the programs which can be executed on a Apple II microcomputer using the Apple Language System. This system gives the researcher the opportunity to learn to handle sequence data, and it also includes a word processing system useful in writing letters and manuscripts and storing text.

A dBASE III surgical pathology reporting and encoding microcomputer system.

The authors have developed a menu-driven dBASE III system for surgical pathology reporting and encoding in Systematized Nomenclature of Medicine (SNOMED). The system requires no knowledge of dBASE and is readily installed on any IBM-standard personal computer equipped with a fixed disk. The use of dBASE memo fields provides the integration of word processing and database functions. Preliminary gross examination reports are automatically accompanied by data from former cases on the same patient. Patient demographics, SNOMED codes, and final diagnoses are stored on the fixed disk; complete reports are saved on floppy diskettes. Cases can be retrieved by patient name, surgical number, or SNOMED codes. Daily work lists, frozen section-final diagnosis correlations, turnaround time reports, and listings of incomplete cases are easily obtained. Cytologic results can also be entered, allowing automatic correlation with surgical cases.

Sample size calculation, power analysis and randomization: research project design in Windows.

Single estimates of sample size for a study may be easily obtained by use of a hand calculator or from published tables. In contrast, performing multiple calculations is a tedious and time-consuming task, which is greatly simplified by a computer program. The computer program presented here assists the investigator in calculating sample size estimates, determining statistical power and creating randomization tables for a study. The program is designed primarily for clinical trials and thus includes some features not found in other software packages performing similar tasks. Sample size calculation and power analysis are performed for dichotomous, continuous (parametric and non-parametric tests) and time-to-failure (exponential distribution and log-rank test) response variables, and for correlation coefficients. Sample size estimates and significance levels may be adjusted for multiple participating centers, non-compliance, interim analyses and.multiple testing. The randomization subroutine generates tables for studies with up to nine treatment arms and with any valid block size. As a Windows application, the program runs in a multitasking environment, allowing switching between programs and easy pasting of results into word-processing documents and other applications. It is very simple to use, with a completely menudriven interface and sufficient built-in help to obviate the use of a manual.

Brain activity during reading. The effects of exposure duration and task.

Brain activity during reading tasks was investigated using PET. The aim was to account for differences in the results of two previous studies [those of Petersen et al. (Science 1990; 249: 1041-4) and Howard et al. (Brain 1992; 115: 1769-82)] by systematically varying the type of reading task and the exposure duration of the word stimuli. Both variables strongly influenced patterns of brain activity. There were three types of task: (i) reading aloud; (ii) reading silently; and (iii) lexical decision on visually presented words and pseudowords. Reading aloud and reading silently engaged the left middle and superior temporal regions, confirming the important role of these areas in visual word processing. The areas principally engaged during lexical decision were the left inferior and middle frontal cortices and the supplementary motor area; activity in these areas suggests that the subjects were using a phonological strategy to perform the task. There was also a significant effect of exposure duration, with activity being greater for short (150 ms) exposure durations than for long (1000 ms or 981 ms) exposure durations. We conclude that until we understand how subtle variations in experimental design influence brain activity during reading tasks, the association of specific processing functions with individual anatomical areas activated during reading is premature.

Assembly of overlapping DNA sequences by a program written in BASIC for 64K CP/M and MS-DOS IBM-compatible microcomputers.

The SEQALIGN programs1 described in this report aid in the assembly of up to 100 individual overlapping DNA sequences generated by M-13 subcloning and sequencing methods. The program produces a printout of the aligned sequences presented in register. Use of the program will be facilitated because 1) it is written with the Microsoft BASIC interpreter, 2) sequence data may be entered and edited using WORDSTAR or similar word processing programs, and 3) hardware requirements for execution of the program on CP/M or MS-DOS (IBM-PC compatible) systems are minimal.

A DNA sequence analysis program for the Apple Macintosh.

This paper describes a new set of programs for analyzing DNA sequences using the Apple Macintosh computer, a computer ideally suited for this kind of analysis. Because of the Macintosh interface and the availability of high quality software-only speech synthesis, these programs are truly easy to use. Instead of typing in commands, the user directs the program by making selections with the mouse, thereby eliminating most typographical and syntax errors. Output options are selected by "pressing buttons" and then clicking "OK" with the mouse. DNA sequences are confirmed by having the program speak them. The high resolution graphics on the Macintosh not only allow for explanatory diagrams to be used to aid in deciding on input parameters, but can be used to produce slides for presentations and figures for papers. Because of the clipboard and the ability of the Macintosh to readily share data among different applications, data can be saved for use directly in word processing documents (e.g. manuscripts).

Apple Macintosh programs for nucleic and protein sequence analyses.

This paper describes a package of programs for handling and analyzing nucleic acid and protein sequences using the Apple Macintosh microcomputer. There are three important features of these programs: first, because of the now classical Macintosh interface the programs can be easily used by persons with little or no computer experience. Second, it is possible to save all the data, written in an editable scrolling text window or drawn in a graphic window, as files that can be directly used either as word processing documents or as picture documents. Third, sequences can be easily exchanged with any other computer. The package is composed of thirteen programs, written in Pascal programming language.

Computer use and education in radiology residency programs.

Computers play an increasingly important role in radiology education and research. We surveyed all U.S. residency programs to assess computer availability, education, and use by residents. Out of 210 questionnaires sent, 132 were returned (63% response). Areas of inquiry included computer equipment and software as well as resident use of facilities. Opinions were also solicited concerning the importance of computer literacy and education. Sixty-nine percent of the respondents have computer facilities (61% within the department). Predominant uses include scientific papers, slides/audiovisual presentations and resume preparation. Popular software includes word processing, spreadsheets, databases and graphics. Of those training programs with computers, 85% provided computer education, and most (70%) felt computer training was very important. Forty-seven percent expected their residents to have at least passing acquaintance with computers. However, in 60% of programs with computers, the computers are used by less than half the residents. Of those programs without a computer, 61% provided no computer training, and only 44% felt computer education was very important. A sizable minority of radiology residency programs are still without computer facilities. Those programs that have computers tend to place a greater emphasis on computer education and literacy for radiology residents. However, even in programs that have computers, it seems they are often underutilized by residents.

A more cost-effective method of preoperative computerized imaging.

Stimulated by the explosive expansion of the computerized desk top publishing industry during the past few years, microcomputer hardware and software are evolving at a staggering rate. Memory is rapidly increasing, and prices are declining. I have found that with the hardware and software described in this paper, I was able to obtain, in a much more cost-effective manner, as useful preoperative information for my practice as I could obtain with more expensive "turnkey" (only one use) computerized imaging systems. This type of microcomputer, of course, is not limited to just the imaging system, but can be used for a variety of other programs as well, such as word processing, slide labeling and production, spreadsheet functions, billing and filing, and numerous business and other applications. The ease of use with readily available 35-mm slides of my patients has greatly enhanced the appeal of this system. Computerized imaging, when used as an educational tool, can be very helpful in preoperative planning, resident teaching, and for illustration and discussion of a patient's proposed surgery. The electronic imaging disclaimer compiled by the American Society of Plastic and Reconstructive Surgeons has been extremely helpful in clarifying the limits of computerized imaging and reducing any false expectations that my patients might have. All of us are experiencing the dawn of a very exciting evolution.

A microcomputer-based information storage and retrieval system for the maintenance of records for a culture collection.

A microcomputer-based system for the storage and retrieval of information on strains in a culture collection is described. The system was designed around commercially available software packages written for microcomputers. Two additional programs were written using the BASIC language to allow a catalogue of the culture collection to be printed in a specific format. The details of each strain in the collection were stored on a floppy disc. Details of new strains were added to this database and information relating to existing cultures was modified or, where necessary, deleted from the collection. The database can be searched to supply details of a particular culture or to identify those cultures which possess certain attributes. The records for the whole collection were sorted alphabetically by species name, and numerically by accession number, and a word-processing package was used to print a catalogue of the culture collection.

Design and preparation of a formulary--guide to the prescribing of medicines.

In recent years there has been a renewed interest in the use of local hospital 'formularies'. The development and preparation at The London Hospital (Whitechapel) of a guide of prescribing which embraces and extends the concept of a formulary is described. A method of involving staff in the preparation of text was developed to ensure the rapid production of a reasonably comprehensive guide which would command respect and a high degree of compliance. The use of word-processing techniques and graphic design expertise are described. The guide has been carefully introduced together with plans for monitoring compliance and its influence on drug expenditure. These are discussed in the light of one year's experience with the guide.

Sentence imitation by adolescents and young adults with Down's syndrome and other intellectual disabilities.

Sentence imitation performance was evaluated longitudinally in 26 adolescents and young adults with Down's syndrome (DS), and 26 age- and IQ-matched non-DS individuals with other causes of intellectual disability (ID). In each of three annual assessments, the DS group began sentence repetitions more slowly and imitated sentences less accurately than the ID group. DS sentence repetition accuracy was equivalent to the ID group only for two-word sentences and was poorer for every other sentence length. Comparisons of sentence imitation and auditory digit span scores suggested that only ID subjects benefitted from the additional meaning and structure provided by sentences. Correlational analyses performed between each year's sentence imitation score and a set of language, memory and hearing measures revealed that sentence imitation was related to grammatical comprehension, auditory short-term memory and IQ in both groups, and to expressive language ability, speed of spoken word processing, speech discrimination and acoustic reflexes in the DS group only. A significant relationship between sentence imitation and middle-ear functioning was further supported by a categorical analysis in which DS subjects with bilateral abnormal tympanograms tended to perform more poorly on sentence imitation tasks than DS subjects with at least one normal tympanogram. It was concluded that sentence imitation is a task that is sensitive to the auditory-perceptual, cognitive and expressive difficulties evidenced by individuals with DS.

Microcomputers and microprocessors in urology: present and future.

Urology departments have a heavy outpatient workload requiring efficient secretarial, appointments and records services. Microcomputers are relatively inexpensive and can facilitate efficient routine clinical and research work. Unlike mainframe computers, formal training is not usually required, a simple introduction being sufficient for the enthusiast. An Apple computer is used in this department for word processing incorporating standard letters, paragraphs and phrases. With more sophisticated programs urological screening by computer interrogation could be linked to an appointments system to coordinate investigations, minimising hospital visits. Microprocessors can facilitate a wide variety of measurement recording and data handling. Urodynamic measurements can be computed and graphs superimposed to facilitate interpretation.
