    ESTIMATION OF FETAL WEIGHT FROM ULTRASONIC MEASUREMENT OF TRUNK CIRCUMFERENCE (1975)

    Notes: A new method of estimating fetal weight from the circumference of the fetal trunk, measured by ultrasound, is described. Comparison of weights estimated in this way with the actual birth weights of 50 fetuses, delivered not more than 48 hours later, shows a mean error in prediction of only 75 g, and in 94 per cent the error was less than 145 g. With such accuracy, the method is of clinical value, particularly in anticipating difficult delivery and in monitoring growth of the fetus at risk.

    Notes: A 3.3-cm period Nd-Fe-B hybrid undulator has been designed and successfully operated in the Cornell Electron Storage Ring (CESR). This 2-m-long, 123-pole insertion device is a prototype of one of the undulators planned for the Advanced Photon Source. In dedicated operation, the undulator produced the expected brightness at 5.437 GeV with the fundamental x-ray energy ranging from 4.3 to 7.9 keV corresponding to a change in gap from 1.5 to 2.8 cm.

    Notes: Six undulators have been designed and built by STI since 1980 for synchrotron and FEL applications. Several design concepts, producing successively higher fields, have been developed during this period. A wedged-pole hybrid design has been demonstrated to yield the highest field to date for a given gap-to-wavelength ratio. A simple method of reducing field errors has been demonstrated on the wedged-pole hybrid, and it may lead to significant cost reduction through relaxation of mechanical and magnet tolerances.

    Recognition of internal derangements (2004)

    Notes: summary  One of the most common symptoms of temporomandibular disorders is an internal derangement (ID). The aim of this study was to test the inter-observer reliability of the recognition of IDs by means of auscultation, palpation or both. To that end, 120 women and 100 men were screened by two trained examiners for the presence of IDs. Anterior disc displacement was diagnosed in 14% of the cases and hypermobility in 12%. In 4% of the cases, the ID was classified as ‘other’. The inter-rater reliability (Cohen's kappa) was moderate for the presence of an ID for all techniques, while for the classification into type, an almost perfect reliability was found for the combined technique. It was concluded that the type of ID can best be established with the combination of auscultation and palpation; for the establishment of an ID as such, any of the three techniques would suffice.

    Solving inequities in provider distribution: loan repayment (2002)
    Oxford, UK : Blackwell Science Ltd
    Health & social care in the community 10 (2002), S. 0

    Notes: The distribution of primary health care professionals in England and Wales is inequitable, with relatively lower concentrations of professionals in deprived areas. The objective of the present study was to determine whether graduate health professionals would be willing to work in under-served areas in return for educational loan repayment. The study group consisted of a convenience sample of 50 newly qualified and trainee general practitioners, and 50 newly qualified community nurses and health visitors in mid- and west Wales. At interview, the subjects were presented with descriptions of general practices and asked to indicate their preferred practice. Practice descriptions varied systematically in terms of location (i.e. urban, suburban and rural), population deprivation (i.e. deprived or mixed affluent/deprived) and availability of loan repayment (i.e. none or loans paid off over a period of between one and 4 years). The main outcome was the probability that a practice with loan repayment was chosen. Compared with a suburban practice, a one-year loan repayment option made the rural and urban deprived practices 1.6 times and 1.2 times more likely to be chosen, respectively. Nurses were generally more willing than doctors to work in a deprived area in return for loan repayment. The findings suggest that loan repayment may offset health professionals’ aversion to working in deprived areas. Such a scheme needs to be piloted to see whether it does offer value for money in recruiting health professionals to under-served areas.

    The clinical assessment of TMJ sounds by means of auscultation, palpation or both (2002)

    Notes: Anterior disc displacements are an important diagnostic subgroup (Group II) of TM disorders according to the Research Diagnostic Criteria (RDC; Dworkin & LeResche, 1992). Although the RDC yields clear-cut criteria for the diagnosis of a disc displacement, the interobserver reliability for the clinical recognition of joint sounds is highly variable. This high variance may be caused by the fact that the clinical assessment of joint sounds is difficult. In many previous studies, auscultation with a stethoscope was used. This technique is often claimed to be the most reliable one. However, it is unclear whether in these studies, auscultation was performed without simultaneous palpation of the contralateral joint. Therefore, the aim of the present study was to test the interobserver reliability of the clinical assessment of TMJ sounds by means of auscultation, palpation or both. A total of 220 undergraduate students (100 men; 120 women; mean age 21·9 ± 3·6 years) was examined independently by two calibrated dentists for the presence, probable presence or absence of sounds caused by anterior disc displacement, hypermobility, or another cause. The 79 students underwent auscultation only (i.e. without contralateral manual palpation); 87 students underwent bilateral palpation; the remainder (54 students) was subjected to both auscultation and palpation. The results show that the combination technique yields the highest reliability (Cohen's κ=0·53). For other techniques, κ-values of 0·46 (auscultation) and 0·48 (palpation) were found. It was concluded that the combination of auscultation and palpation yields the highest interobserver reliability for the recognition of TMJ sounds, although the differences with other techniques were small.

    Variation in masticatory muscle activity during subsequent, submaximal clenching efforts (2002)

    Notes: In previous studies to the relative contribution of the jaw closing muscles to the maintenance of submaximal clenching levels, a considerable variation in the electromyography (EMG) activities of these muscles during subsequent efforts was found. In this study, it was examined to what extent this variation could be explained by coincidental variations in mandibular positioning. From seven healthy individuals, a total of 90 EMG sweeps was recorded: three conditions (intercuspal position and two types of stabilization appliances) × three clenching levels (10, 30 and 50% of maximum voluntary contraction level) × 10 repetitions. Mandibular position was monitored with a six degrees of freedom opto-electronic jaw movement recording system. Variations in mandibular positioning during subsequent, submaximal clenching efforts explained up to 25% of the variance in the indices that quantify the relative contribution of the jaw closing muscles to the total clenching effort (P=0·000; ANOVA). Only a weak dependency of positioning upon clenching condition was found whereas during higher clenching levels, the positioning effect tended to be smaller than during lower levels. In conclusion small, coincidental variations in mandibular positioning during subsequent clenching efforts partly explain the variance in EMG activity of jaw closing muscles, especially at lower clenching levels.
