    Notes: Summary. Placental bed biopsies were obtained at caesarean section from 34 women. Their plasma urate was directly related to maximum mean arterial pressure and inversely to adjusted birthweight; but it was related most closely to the histological appearances of the spiral arteries in the placental bed. Nine women had physiological changes in the spiral arteries: their mean urate (233, SD 28·9 μmol/l) was significantly (P 〈0·00l) lower than the mean urate in those who did not have adequate physiological changes (339, SD 90·3 μmo1/l) or that in the nine women who had atherosis (397, SD 153·2 μmol/l). Raised plasma urate appears to be better related to maternal vascular pathology than to the clinical condition or infant birthweight.

    Notes: Summary. Biopsy of the placental bed was attempted at caesarean section in 109 patients: 77 consecutive and 32 selected because of the maternal or fetal condition. Forty-seven (44%) of these biopsies were from the placental bed and contained spiral arteries suitable for comment. Histological examination separated the patients into four groups: comprising 11 whose vessels showed normal physiological changes, 20 who showed inadequate physiological change, 12 with acute atherosis, and four with a mixed pattern. There was no relation between these changes and maternal age, parity, race or smoking habit, but no physiological change and atherosis were more common in association with maternal hypertension. Mean adjusted birthweight was greatest in those with physiological changes, less in those without physiological changes or the mixed pattern, and least in those with atherosis. The four patients in the mixed group did not have any unifying clinical characteristics.

    Notes: Summary. Whole body radiographs were made in a consecutive series of 488 infants who were either stillborn or died within the first month of life; autopsies were done in 378. The radiographs were considered to have been useful, or diagnostic in 16% overall, in 100% of infants with dwarfism, in 40% where there were external malformations; and in 9% where there were no external malformations.

    Notes: Background and aims : Considerable difficulties persist amongst pathologists in agreeing on the presence and severity of gastric atrophy. An international group of pathologists pursued the following aims: (i) to generate an acceptable definition and a simple reproducible classification of gastric atrophy; and (ii) to develop guidelines for the recognition of atrophy useful for increasing agreement among observers.Methods : After redefining atrophy as the ‘loss of appropriate glands’ and examining histological samples from different gastric compartments, three categories were identified: (i) negative; (ii) indefinite; (iii) atrophy, with and without intestinalization. Atrophy was graded on a three-level scale. Interobserver reproducibility of the classification was tested by κ statistics (general and weighted) in a series of 48 cases.Results : The medians of the general agreement and weighted κ values were 0.78 and 0.73, respectively. The weighted κ coefficients, obtained by cross-tabulating the evaluation of each pathologist against all others, were, with only one exception, 〉 0.4 (moderate to excellent agreement).Conclusions : By using the definition of atrophy as the loss of appropriate glands and distinguishing the two main morphological entities of metaplastic and non-metaplastic types, a high level of agreement was achieved by a group of gastrointestinal pathologists trained in different cultural contexts.

    Notes: Northumbrian Water Limited has thirty-four bathing waters and a substantial investment programme to ensure that these waters meet EC standards by 1995. One project within this overall programme is the Seaton Carew Sewerage Scheme. Seaton Carew lies on the southern edge of Hartlepool which has a population of 95000. The scheme will combine existing flows into new foul and storm-sewage outfalls. The headworks will incorporate screening, grit removal and pumping stations with substantial measures for odour control. Hydraulic operating regimes using active pump control and passive flume control have been investigated to ensure efficient treatment for a wide range of flows. The onerous design, manufacture and construction programme has required the development of new approaches to procuring the work, whilst maintaining a substantial element of competition. The various programmes have been substantially overlapped to ensure that the scheme is completed by April 1993.
