    Notes: A postal questionnaire survey of neurosurgery and spinal injury departments in the UK was conducted to determine how they assessed the cervical spine in unconscious, adult trauma patients, and at what point immobilisation was discontinued. Of the 32 units contacted, 27 responded (response rate, 84%). Most centres had no protocols to guide initial imaging or when immobilisation devices should be removed. Most responding centres performed fewer than three plain radiographs, and most did not use computerised tomography routinely. Routine use of magnetic resonance imaging or dynamic flexion–extension fluoroscopy was rare, and few units regarded the latter as safe in unconscious patients. There was no consensus on when immobilisation of the cervical spine should be discontinued. Most centres that terminated immobilisation immediately after imaging did so on the basis of plain radiographs alone. Unconscious adult trauma patients remain at risk of inadequate assessment of potential cervical spine injuries.

    Notes: The Cardiff paediatric laryngoscope blade is a single blade that has been designed for use in children from birth to adolescence. This open, randomised, crossover study compared the Cardiff blade with the straight, size 1, Miller laryngoscope blade in 39 infants under 1 years of age and the curved, size 2, Macintosh blade in 39 children aged 1–16 years. The same laryngoscopic view was obtained with the Cardiff and Miller blades in 26 patients; the view was better with the Cardiff blade in seven patients and better with the Miller blade in six (median (IQR [range]) grade of laryngoscopy 1 (1–2 [1–3]) vs. 1 (1–2 [1–3]), respectively; p = 0.405). The Cardiff blade was faster at gaining a view than the Miller blade (mean (SD) time 8.5 (2.9) s vs. 10.2 (3.5) s, respectively; 95% CI for difference −2.8 to −0.4; p = 0.009). The Cardiff and Macintosh blades produced the same view in 32 patients; the view was better with the Cardiff blade in seven patients (median (IQR [range]) grade of laryngoscopy 1 (1–1 [1–3]) vs. 1 (1–2 [1–3]), respectively; p = 0.008). There was no difference in time to gain these views: mean (SD) 8.7 (3.0) s vs. 9.3 (2.7) s, respectively (95% CI for difference −1.58 to 0.40; p = 0.237). The Cardiff paediatric laryngoscope blade compares favourably with these two established laryngoscope blades in children.

    Notes: IRAS (infrared reflection absorption spectroscopy) has been employed to study the isotopic mixing reaction: 13C16O(a)+12C18O(a)→13C18O(a)+12C16O(a) on Ni(111) with preadsorbed K adatoms. Under high temperature conditions (T〉450 K) where the isotopically mixed CO is being desorbed, it has been shown that the isotopic exchange reaction cannot be detected by IRAS on the surface among CO molecules strongly interacting with K adatoms. This result implies that dissociation of CO occurs at K-promoted Ni sites followed by surface diffusion of C(a) and O(a) away from the K promoter site. Statistical recombination of C(a)+O(a) occurs with concomitant CO desorption on Ni(111) sites some distance from K centers. The empty K-promoted sites may be refilled by surface diffusion of CO from outside. Thus, alkali metal promotion of C–O bond scission may act via a "feeder-site'' mechanism connecting promoter atoms to external surface sites via surface diffusion of atomic C and O species.

    Notes: We report the successful application of an optically pumped molecular beam laser for efficient and selective population transfer from v″=0 to high lying vibrational levels of Na2 in the electronic ground state. More than 50% of the molecules in a thermally populated rotational level of v″=0 can be transferred to a state v″(very-much-greater-than)1 with typically ≥75% of the molecules excited out of the initial state found in the predetermined end vibrational level and approximately ≤25% distributed over other levels according to the Franck–Condon factors. The applicability of this technique to the study of collision processes involving vibrationally highly excited levels is discussed. This work also contributes in general to a better understanding of optically pumped dimer lasers.

    Notes: The RNA components of two isolates of BaYMV from Streatley and Wiltshire were analysed by agarose gel electrophoresis. Northern blots of extracts of both isolates analysed with random-primed cDNA probes to RNA1 and 2 of the Streatley isolate showed little or no sequence homologies between the two isolates, confirming other evidence that they should be considered as different viruses.

    Notes: Juvenile Cherax destructor (commonly called the yabby) (mean weight 48.3 mg) were cultured intensively (stocking density 360/m2) under controlled conditions for 48 days. The animals were provided with a combination of food (high protein pellets and/or natural feed organisms attached to a conditioned synthetic substrate) and refuge. Fastest growth and highest yield was recorded when both pellets and the conditioned synthetic material were provided. Although the yabbies sheltered in the synthetic substrate, it did not increase survival. Juvenile yabbies (〈 200 mg) were able to graze on small organisms attached to the synthetic material but this ability appeared to decline as the yabbies grew to a larger size. The use of artificial substrates in the intensive nursery phase production of juvenile freshwater crayfish is discussed.

    Notes: Abstract This paper reports an examination of dental caries in the primary dentition of 2–5-yr-oId white children in an industrialized South African city, in 1981 and 1983. There was a decrease in dental caries prevalence over the 2-yr period accompanied by an increase in dental treatment in 3–5-yr-olds. Treatment, however, remains low. Socioeconomic status had a varying effect on the trends, but in general there was a greater reduction in dental caries in the lower socioeconomic areas.

    Notes: Abstract – As part of a series of frequent epidemiological field studies to determine caries prevalences in the primary dentition of young South African children, 1436 children of 1–4 yr of age from five ethnic groups were examined. Using WHO diagnostic criteria decayed, missing, and filled surfaces were determined with mirror and probe and caries free, dmfs, dfs, ds, mfs, and dmft scores were calculated. The investigation has shown that urban coloured and Indian children have the highest caries prevalences and urban white children have the lowest. It is suggested that the percentage of caries-free children should be used to set goals for reduction in caries.
