Abstract We report a case of successful external cephalic version after preterm premature rupture of membranes. Transcervical amnioinfusion was used to facilitate the procedure due to minimal amniotic fluid, and the patient subsequently delivered vaginally. A femoral fracture was later identified in the neonate.

ABSTRACT The results for a real-time PCR assay, using the LightCycler Strep B analyte-specific reagents (Roche Diagnostics Corporation, Indianapolis, Ind.), were compared to a direct plate method combined with a broth enrichment culture method for detection of group B streptococcus colonization in pregnant women. Two separate evaluations were conducted using two different automated nucleic extraction instruments, the MagNA Pure LC instrument (Roche Diagnostics Corporation) and the lower-capacity MagNA Pure Compact instrument (Roche Diagnostics Corporation). The sensitivities, specificities, and positive and negative predictive values for the different evaluation methods were as follow: for the LightCycler Strep B assay with MagNA Pure LC, 100, 97, 90, and 100%, respectively; for the LightCycler Strep B assay with MagNA Pure Compact, 92.5, 99, 97, and 97.5%, respectively. The LightCycler Strep B assay combined with either MagNA Pure LC or MagNA Pure Compact extraction is a suitable method for detecting group B streptococcus colonization in pregnant women. An advantage of the LightCycler assay over culture is the considerably reduced turnaround time for results.
