OBJECTIVE: To evaluate whether the dimensions of the cones removed during large loop excision of the transformation zone have decreased over time. Secondly, whether these changes were associated with a lower risk of obstetrical harms on a subsequent pregnancy. STUDY DESIGN: A retrospective matched cohort study was performed in a tertiary referral unit in Belgium. A total of 97 women were identified from a database of women who underwent excisional treatment for cervical precancer between January 1st, 2004 and December 31st, 2012, and delivered before December 31st, 2014...

OBJECTIVE: A paucity of effective interventions exists for the prevention of preterm birth (PTB). Renewed interest has focused on cervical pessaries, which have the benefits of being inexpensive, nonsurgical, and easily inserted and removed. In this study, we aim to describe our experience with this device in a Canadian tertiary care centre. Primary outcomes were rates of spontaneous or iatrogenic PTB before 37, 34, and 28 weeks gestation in pregnancies complicated by short cervix treated with cervical pessary...

REVIEW
Dinesh Dadarwal, Colin Palmer, Philip Griebel
In this review, mucosal immune defense mechanisms used to control infections in the bovine genital tract (vestibule, vagina, cervix, uterus and oviduct) during the postpartum period are reviewed. Knowledge gaps are highlighted to emphasize the need for further investigations. Physical barriers to the entry of microbes include vulvar sealing, vestibule-vaginal constriction, a narrow cervical opening and the mucosal epithelium along with the overlying mucus layer. Genital tract mucosal epithelial cells recognize damage-associated molecular patterns and pathogen-associated molecular patterns and respond by secreting antimicrobial peptides and cytokines to recruit and activate immune cells...

Progesterone helps maintain cervical structure during pregnancy via the progesterone receptor (PR). Two PR isoforms exist, PR-A and PR-B, which have overlapping as well as isoform-specific target genes. During late gestation, leukocytes infiltrate the cervical stroma accompanied by increased cervical cytokine levels, resembling an inflammatory process. We examined interleukin (IL)-1β regulation of the expression of PR-A, PR-B, and genes governing prostaglandin synthesis in human cervical fibroblasts (HCFs)...

Monitoring cervical structure and composition during pregnancy has high potential for prediction of preterm birth (PTB), a problem affecting 15 million newborns annually. We use in vivo Raman spectroscopy, a label-free, light-based method that provides a molecular fingerprint to non-invasively investigate normal and impaired cervical remodeling. Prostaglandins stimulate uterine contractions and are clinically used for cervical ripening during pregnancy. Deletion of cyclooxygenase-1 (Cox-1), an enzyme involved in production of these prostaglandins, results in delayed parturition in mice...

BACKGROUND: Advances in cervical cancer management for childbearing women have led to less radical approaches. Use of fertility-sparing treatment to treat small cell neuroendocrine carcinoma (SCNEC) is challenging owing to the aggressive nature of the disease, even in early stage disease. CASE PRESENTATION: A 25-year-old nulligravida woman presented with malodorous vaginal discharge and was diagnosed to have an exophytic cervical SCNEC. A magnetic resonance image scan showed no evidence of parametrial invasion or distant metastasis...
