The impact of national guidance for anomaly screening and invasive testing: unintended consequences

Recent guidance from the UK National Screening Committee (NSC) and the Fetal Anomaly Screening Programme (FASP) has led to important changes in prenatal ultrasound diagnosis and invasive testing. These relate to prenatal ultrasound investigation of what were previously known as 'soft markers' for Down's syndrome at the time of the detailed anomaly scan and as to whether full karyotype or FISH (fluorescent in situ hybridisation)/QFPCR (quantitative fluorescence PCR) testing for trisomies should be carried out when an invasive test is performed. Neither recommendation is directly related to the other but both in combination could have profound implications for the detection of chromosomal abnormalities other than trisomy 21 (Down's syndrome). In the light of two cases recently managed in one regional fetal medicine unit, we retrospectively reviewed cases where, with correct application of the NSC and FASP recommendations, non-lethal and clinically important chromosomal abnormalities would most likely not have been detected.

Cardiac function in early onset small for gestational age and growth restricted fetuses

OBJECTIVE

To examine cardiac function in appropriately grown, small for gestational age and intrauterine growth restricted fetuses and investigate the relationship between cardiac function and fetal arterial and venous Doppler parameters.

STUDY DESIGN

Myocardial performance index, isovolumetric contraction time, isovolumetric relaxation time, ejection time, and umbilical artery, middle cerebral artery and ductus venosus Doppler pulsatility index were measured for women between 24 and 32 weeks with small for gestational age and intrauterine growth restricted fetuses. Forty-eight appropriately grown, 11 small for gestational age and 12 intrauterine growth restricted cases were included. The relationship between cardiovascular parameters and gestation was defined and Doppler values converted to Z-scores in relation to gestational age.

RESULTS

In small for gestational age fetuses and fetuses with intrauterine growth restriction the myocardial performance index was 0.66 (0.63-0.7) and 0.64 (0.60-0.67), respectively, and compared to appropriately grown fetuses, at 0.45 (0.43-0.47), was significantly increased (p=0.001). No relationship was found between the myocardial performance index and arterial and venous Doppler Z-score.

CONCLUSION

Small for gestational age and intrauterine growth restricted fetuses demonstrate altered cardiac function in the late second and early third trimester of pregnancy. Importantly, the myocardial performance index is raised in small for gestational age fetuses before the arterial and venous Doppler abnormalities that characterize hypoxia are evident.

EBCOG Hospital Recognition: where do we stand?

Hospital Recognition for general Ob/Gyn training programmes was started by EBCOG (European Board & College of Obstetrics & Gynaecology) in 1996 and for subspecialty Ob/Gyn training programmes in 2005, the latter jointly with the four European scientific organisations representing the subspecialties. So far, 85 Audits/Visits have been -conducted by EBCOG for general Ob/Gyn training and a good start has been made for subspecialty training, in particular-- Gynaecological Oncology. EBCOG Visits are conducted by two EBCOG representatives and one trainee appointed by ENTOG (European Network for Trainees in Obstetrics & Gynaecology) for general Ob/Gyn training -programmes and by two subspecialty specialists and an EBCOG representative for subspecialty programmes. Each Visit lasts one day. Accredition is granted by the EBCOG Executive Board depending on the Visiting report. Ultimately, EBCOG would like to see the introduction of an auditing and accreditation system for general and subspecialty Ob/Gyn training programmes in each country in Europe.

A software tool for fetal blood flow analysis

Doppler ultrasonography is a widely used technique for determination of the fetal blood flow pattern. Determination of the waveform qualities was done manually, with considerable inter- and intraobserver variations. In order to limit the variations and the time-consuming data entry, a Fetal Blood Flow Analysis software program was developed to facilitate ease of determination of Doppler signals. This article describes the development and unique features of the software program, made specifically to meet the obstetric and gynecology department's needs.
