Evaluation of a rapid optical immunoassay-based test for group B streptococcus colonization in intrapartum patients

Objective.?To investigate the association between cleft lip and/or palate and perinatal mortality.

Methods.?A retrospective review was performed of cases of cleft lip/palate born to West Midlands residents from 1995 to 1997. Perinatal mortality for identified cases was compared with all births from 1995 to 1997.

Results.?347 cases of cleft lip and/or cleft palate were delivered from 1995 to 1997. Thirty-six pregnancies were terminated due to parental wishes - 2 were registerable births. There were 310 spontaneous registerable births (stillbirths/livebirths) with cleft lip and/or palate and 1 further late fetal loss. In 220 (70.5%), the lesion was isolated. Of these, there were 7 perinatal deaths, 5 had post mortems and no additional anomalies were identified. In 92 (29.5%) cases other abnormalities were identified. The overall perinatal mortality rate (PNMR) in the West Midlands, was 10.0/1000 total births. The overall PNMR for babies with facial clefts was 89.7/1000 total births. The PNMR for those with associated anomalies was 228.3/1000 live/still births. The PNMR for isolated facial clefts was 31.8/1000 live/still births, significantly higher than the background population (OR 3.3, 95% CI: 1.5–7.0).

Conclusion.?Consideration should be given to screening the fetus at 20–24 weeks for facial deformity. This has implications for detection both of fetal anomalies and of a population at risk for adverse outcome.
