Objective: To evaluate the accuracy of cervical effacement reported as a percentage by digital cervical exams using cervical length determined by transvaginal ultrasonography as a standard. Methods: Records of pregnant women who had a digital cervical exam and subsequent transvaginal ultrasound scan for cervical length between January 2005 and December 2008 were reviewed. Digital cervical exams were performed by different examiners. Transvaginal ultrasound was performed by one examiner who did not perform any of the digital exams. Cervical effacements were recorded as a percentage and cervical lengths were measured in centimeters. Results: A total of 173 women met the study criteria. Average cervical length for 0% effacement was 3.3 ± 1.1 cm (0.8 - 5.0 cm);20% effacement, 1.6 ± 1.0 cm (0.9 - 3.0 cm);25% effacement, 2.2 ± 0.2 cm (2.0 - 2.3 cm);30% effacement, 2.6 ± 0.4 cm (2.1 - 3.0 cm);40% effacement, 3.0 ± 0.4 cm (2.6 - 3.4 cm);50% effacement, 2.4 ± 1.1 cm (0.6 - 4.6 cm);60% effacement, 2.3 ± 1.4 cm (0.7 - 4.3 cm);70% effacement, 2.2 ± 0.8 cm (1.1 - 3.3 cm);75% effacement, 1.7 ± 1.4 cm (0.7 - 2.7 cm);80% effacement, 2.0 ± 0.9 cm (0.6 - 4.4 cm);90% effacement, 0.7 ± 0.4 cm (0.4 - 0.9 cm);100% effacement, 1.2 ± 1.5 cm (0.3 - 3.0 cm). The coefficient of variation ranges from 10% - 124%. Conclusion: The traditional method of reporting cervical effacement as a percentage is unacceptably inaccurate compared to the actual cervical length determined by vaginal probe ultrasound.

<i>Citrobacter rodentium</i>, a Gut Pathogen: The Yin and the Yang of Its Pathophysiology, Immunity and Clinical Manifestation in Mice

Pathogenic strains of E. coli including enteropathogenic E. coli (EPEC), enterohemorrhagic E. coli (EHEC), enterotoxigenic E. coli (ETEC) are principle causes for diarrhoea in many parts of the globe. Citrobacter rodentium (C. rodentium), a gram negative bacterium, is a murine pathogen that also utilizes type III secretion system and similar virulence factors to EPEC and EHEC and forms comparable attaching/effacing lesions in the intestines as EPEC and EHEC. The infection caused by C. rodentium in mice is usually self-limiting and results in only minor systemic effects with higher mortality in some susceptible mouse strains. All these characteristics have made the bacteria a commonly used model to study host immune responses to pathogenic E. coli infection. In this review, we focus on the impact of virulence factors of the pathogen;different immune components involved in the immune response and summarize their role during C. rodentium infection.
