Risk factors for wound infection following caesarean section.
A prospective study was performed between April 1, 1991 and April 30, 1992 to determine factors involved in the development of post-Caesarean section wound infection. During this period there were 4,857 deliveries, 428 by Caesarean section (8.8%). Complete data were available on 328 (76.6%) patients. Wound infection occurred in 25.3% of women and was confirmed by positive bacteriology in 77.1%; 36% of wound infections were diagnosed following the patients' discharge from hospital. A negative correlation was found between maternal age and development of wound infection up to age 40 (p = 0.03). Maternal weight was a highly significant indicator of subsequent wound infection development (p = 0.0001), the relationship between increasing maternal weight and infection appearing linear. Antibiotic prophylaxis was found to be the most significant protective factor (p = 0.0007) in the reduction of postoperative wound infection. This relationship was independent of maternal weight.
Feasibility of otoacoustic emission detection followed by ABR as a universal neonatal screening test for hearing impairment.
The feasibility of attempting a two-stage universal screening test for auditory impairment was assessed at a large district maternity hospital. The first stage was measurement of otoacoustic emissions using the Programmable Otoacoustic Emission Measurement System. Those failing the first stage proceeded to automated analysis of auditory brainsteam responses. A single tester working for 6 h on 6 days per week attempted to test all babies born between the hours of midday and midnight for 2 weeks and then all babies born between midnight and midday for a further 2 weeks. Of 217 babies born during the study periods, one infant died and three were still receiving intensive care at the end of the study. Of the remaining 213 infants, auditory testing was undertaken in 201 infants (94%). Eight infants (4%) who failed the first stage of the screening test did not undergo the second stage. Of those 193 infants completing the screen, one (0.5%) failed the screen unilaterally. There were no bilateral failures. Three testers, working two and a half whole-time equivalents, should be adequate to achieve a coverage of 90% and a specificity of 99% for this screen in this clinical setting.

Hyperphosphataemia after enemas in childhood: prevention and treatment.
The case of a child with severe hyperphosphataemia and symptomatic hypocalcaemia secondary to retention of phosphate administered through an antegrade continence enema is reported. Caution should be exercised with the use of phosphate enemas and prompt action taken to remedy retention. The use of glucose with insulin in the emergency management of acute hyperphosphataemia is discussed.
