    Notes: Summary. A total of 145 pregnancies clinically suspected of being small-for-dates was studied at presentation with a single measurement of the fetal abdominal circumference and Doppler studies of the umbilical and arcuate arteries. The abdominal circumference measurement gave the best prediction of the small-for-gestational-age (SGA) baby (sensitivity 73%, umbilical artery sensitivity 47%, arcuate artery sensitivity 29%). The umbilical artery measurement gave the best prediction of antenatal fetal compromise; the performance of the tests was compared for a fixed sensitivity of 100% (i. e. all cases of antenatal compromise would be detected), the specificity of the umbilical artery measurement was 77%, abdominal circumference measurement 12% and arcuate artery measurement 2%. In our data, umbilical artery studies were not a sensitive predictor of the SGA baby but they did give an accurate prediction of the potentially compromised SGA fetus.

    Prenatal ultrasound diagnosis: a review of fetal outcome (1993)

    Notes: Abstract Prenatal ultrasound is a very useful investigation to alert the clinician and parents to a potential fetal anomaly and permit appropriate management. In this retrospective series 196 fetal anomalies were identified by ultrasound. In 100 cases the diagnosis was confirmed and complete; in 37 the diagnosis was confirmed but there were additional significant pathological features; in 19 the diagnosis was confirmed but there were additional pathological features of academic interest only; in 16 there were transient prenatal ultrasound features but the baby was normal at birth; and in 21 the anomaly was not confirmed by pathological examination or records of live births were incomplete. Overall, the commonest anomalies were those affecting the central nervous system (35%), genitourinary system (18%), and gastro-intestinal tract (12%). Prior knowledge of anomalies both influenced surgical management and enabled the mother to be appropriately counselled.

    Real time ultrasound scanning of the head in neonates and infants, including a correlation between ultrasound and computed tomography (1985)

    Notes: Abstract The results of ultrasound (US) head scans performed in a children's hospital over a 6 month period have been reviewed and correlated with the results of computed tomography (CT). Two hundred and twenty-four scans were performed on 141 children ranging in age from a few days to 18 months. The clinical indications with which these children were referred were: abnormal neurological symptoms or signs, screening for hydrocephalus in neural tube defects (NTD), enlarging heads, suspected intra-cranial haemorrhage (ICH) and its sequelae, suspected complications of meningitis, investigations of suspected syndromes and following trauma. Twenty-nine of these children also had CT scans. There was good correlation between the two examinations and in only one case (a subdural collection) was a serious abnormality missed by US. US head scanning has been found to be a very reliable technique. It is the initial investigation of choice for imaging the brain of neonates and infants and in many instances it is the only investigation necessary.

    Nucleic acid and protein synthesis in discs cut from mature leaves of Nicotiana tabacum L. and cultured on nutrient agar with and without kinetin (1977)

    Notes: Abstract The effect of kinetin on aspects of the metabolism of discs cut from mature leaves of Nicotiana tabacum and cultured in the light on agar containing mineral salts and sucrose was studied. In the first few days of culture there was a rapid decline in chlorophyll content. Discs treated with kinetin in the light began to resynthesise chlorophyll after 3–4 days and this was correlated with chloroplast replication. Kinetin promoted chloroplast replication but was not always essential. An increase in fresh weight also occurred, due mainly to cell expansion. Nitrate reductase activity increased rapidly during the first few hours after placing discs on the culture medium but kinetin had no effect on this reponse. Subsequently there were dramatic increases in RNA and protein content which were largely independent of kinetin. Gel electrophoresis showed that cytoplasmic and chloroplast ribosomal RNA and a large amount of soluble RNA were synthesised during culture of the discs. These results are discussed in relation to the role of kinetin in delaying leaf sensescence.
