    Notes: Objective To evaluate the accuracy of the OMRON-MIT inflationary oscillometric device for blood pressure measurement in pregnancy and pre-eclampsia.Design Prospective observational study, using validation methods recommended by the British Hypertension Society (BHS) and the Association for the Advancement of Medical Instrumentation (AAMI).Settings Antenatal clinics and ward, Guy's Hospital, London.Population Normotensive pregnant women and those diagnosed with pre-eclampsia according to the definition of the International Society for the Study of Hypertension in Pregnancy.Methods Validation according to BHS protocol.Main outcome measures Proportion of readings within 5, 10 and 15 mmHg (absolute differences) between the automated device and two trained, blinded observers, according to the BHS and AAMI criteria.Results The OMRON-MIT achieved an overall BHS grade B for systolic and grade A for diastolic blood pressure measurement in both pregnancy and pre-eclampsia. The mean (SD) differences between the standard and the test device were −5 (7) mmHg for systolic and 2 (6) mmHg for diastolic blood pressure in pregnancy and −4 (6) mmHg for systolic and 2 (7) mmHg for diastolic blood pressure in pre-eclampsia. This device therefore fulfils the AAMI criteria.Conclusion The OMRON-MIT is the only automated oscillometric device that has proven to be accurate for blood pressure measurement in pre-eclampsia according to the BHS protocol in pregnancy. Inflationary oscillometry may correct the error associated with oscillometric devices in pre-eclampsia.

    Notes: Objective To determine the indications for singleton caesarean sections in Scotland in 1994.Design Prospective survey of singleton caesarean sections using information provided by clinicians entering data onto a computer in labour wards.Setting Twenty-three consultant-led obstetric units in Scotland.Population Women undergoing caesarean section in participating Scottish maternity units during 1994.Results Using routinely collected data it was found that the caesarean section rate varied by maternal age, parity, gestation, history of previous section and hospital of delivery, but there was no difference by area of deprivation. 87.4% (8369/9573) of Scottish caesarean sections were included in the survey of which 8098 were in women with singleton pregnancies. Most singleton caesarean sections were undertaken in primiparae (50.5%), 31.2% were in women with a history of previous section and 18.3% were in multiparous women who had not had a previous section; 38.9% of the operations were elective, 13.9% were emergencies before labour and 47.2% were emergencies during labour. Four main indications—elective section for breech presentation (10.7% of all sections); emergency Caesarean section before labour because of fetal problems (2.8%); emergency caesarean section during labour for fetal distress and/or failure to progress (30.3%); repeat section for reasons other than above (16.2%) accounted for 60% of all Caesarean sections in women with no other recorded complications. 7.7% of all singleton caesarean sections (19.8% of elective operations) were associated with maternal request for the operation.Discussion The survey has identified why caesarean sections are performed by Scottish obstetricians and highlighted some areas where there would be scope to increase the vaginal delivery rate. Before this can be attempted, agreement must be reached by clinicians about effective management of particular problems. Women also need to have ready access to evidenced-based information about caesarean section.

    Notes: [Auszug] The DM locus has been characterized both genetically6"8 and physically9"11 and recent efforts have concentrated on constructing a long-range restriction map12'13 of the critical region. The distance between the genetic markers ERCC1 and D19S51 is -600kilobases (kb)12. Several HTF islands14 ...
