    Notes: A combination of pulsed echo and continuous wave Doppler ultrasound was used to obtain blood flow velocity signals from the umbilical arteries of 10 patients during uncomplicated spontaneous labour. Audio frequency analysis of these signals yielded fetal blood velocity waveforms. Analysis of these waveforms demonstrated that placental vascular resistance to feto-placental blood flow is not altered by uterine contractions, artificial rupture of the membranes, the infusion of oxytocin nor the administration of analgesia during uncomplicated labour.

    Notes: A combination of pulsed echo and continuous wave Doppler ultrasound was used to obtain blood flow velocity signals from the umbilical arteries of 18 normal patients from the 16th until the 40th week of pregnancy. Audio frequency analysis of these signals yielded fetal blood velocity waveforms. Analysis of these waveforms demonstrated that the placenta is an organ of low vascular resistance and that placental resistance to blood flow declines with advancing gestational age in normal pregnancy.

    Notes: Background There is a lack of good data about patient satisfaction with teledermatology and about its potential interaction with quality-of-life factors. Objectives To assess the association between perceived skin-related quality of life and patient satisfaction with a nurse-led teledermatology service. Methods In a mobile nurse-led teledermatology clinic located in four inner city general practices in Manchester, the teledermatology service used digital cameras to capture and store images of skin conditions for remote diagnosis by dermatologists. One hundred and twenty-three adult patients, non-urgent dermatology referrals from primary care, completed the Dermatology Life Quality Index (DLQI) and a 15-item patient satisfaction questionnaire. Results In common with other studies of patient satisfaction, subjects reported highly favourable views of ‘hotel’ aspects of the service (93%) and found it ‘convenient’ (86%). However, 40% of patients would have preferred to have had a conventional face-to-face consultation with a dermatologist, and 17% felt unable to speak freely about their condition. Patient satisfaction with the service was related to quality of life. Patients reporting lower quality of life as measured by the DLQI were more likely to prefer a face-to-face encounter with a dermatologist (r = 0·216, P 〈 0·05), and to evince anxiety about being photographed (r = 0·223, P 〈 0·05). Conclusions Patient acceptance and satisfaction with telemedicine services is complicated by patients' subjective health status. Telehealthcare providers need to recognize that patients with poor quality of life may want and benefit from face-to-face interaction with expert clinicians.

    Notes: Previous work (Brock, Lancet, 2, 197, 1972) has established that Alpha-fetoprotein (AFP) is elevated in amniotic fluid from open neuro-tubular defective pregnancies. This report describes a simple quantitative immunonephelometric method for measurement of AFP in amniotic fluid.Immunonephelometry measures the amount of light scattered by soluble antigen-antibody complexes. Complex formation is proportional to the antigen concentration, resulting in a proportional increase in light scattered. A modified Kallestad nephelometer was used for this study. It consists of a tungsten light source with a filter at 610 nm and two photodetector cells at 90° with respect to light source.The assay procedure requires mixing a 100 μl sample of amniotic fluid with 2 ml of goat anti-AFP (dilution 1:50) in 4% PEG-saline. The assay requires a 60 minute incubation at room temperature. The standard curve covers the range 773 to 21,775 I.U./ml, with a minimum detectable dose of 120 I.U./ml. Precision is good, with an interassay coefficient of variation of 〈 4% using low, medium, and high controls. Recovery of AFP added varied from 92 to 100%. The method correlates well with radioimmunoassay (r = 0.97, n = 37) and the slope is not significantly different from one (p〈0.001).In summary, our nephelometric procedure is rapid, reproducible and sensitive, offering advantages over currently employed methods.

    Notes: Otolith analyses were used to back-calculate young-of-the-year (YOY) yellow perch Perca flavescens hatch-date estimates to interpret broad length distributions observed within a small Great Lake, Lake St. Clair, and a small inland lake, Lake Opinicon, during 1998. For the Great Lake, the earliest observed hatch date occurred 2 weeks after suitable water temperatures and latest hatch dates occurred the same week temperatures were considered too warm for spawning. For the inland lake, the earliest hatch date occurred 4 weeks after suitable water temperatures and the latest hatch dates occurred 2 weeks after the water temperatures were considered too warm for spawning. It is inferred that spawning in each lake had a duration of 〉9 weeks. This suggests that natural perch populations can protract their spawning season opportunistically under the appropriate environmental cues. During 1998, these cues involved a shortened winter, earlier spring, and slow warming to typical summer temperatures, caused by the El Niño-Southern Oscillation. Time of YOY hatch determined the absolute opportunity for growth and resulted in a match or mismatch with optimal foraging conditions and contributed to the development of the observed YOY length distributions.

    Notes: Trained sensory panel scores and Warner-Bratzler shear values (WBS) of emu meat cooked to three end-point temperatures (60, 66, and 75°C), obtained from two bird types (breeder quality, BQ; and nonbreeder quality, NBQ), and from five carcass locations were determined and compared in three studies. NBQ birds had obvious conformational defects. Full rumps and inside drums broiled to 60°C were more tender and juicy than those broiled to 66 or 75°C (P〈0.05). Cooking temperature did not affect meat-flavor intensity (p〉0.05). BQ vs NBQ sources had no effect on tenderness or juiciness (p〉0.05). Differences in tenderness, juiciness, meat-flavor intensity and WBS were found among the five meat cuts (P〈0.05).
