Compliance with follow up cytology after discharge from the colposcopy clinic.
Cervical cancer represents the second common cancer in women and is a major public health issue in Ireland and worldwide. Despite appropriate treatment of precancerous lesions, women with dysplasia are at relatively increased risk, and require follow up. We aimed to evaluate the compliance rate with follow up cytology advice given to patients discharged from the colposcopy clinic and to identify predictive factors for poor compliance. This is a retrospective cohort study of patients initially managed in our institution in 2001. Patients were evaluated for adherence with the recommendations received at the time of discharge from the clinic. Of the 116 women that were initially contacted, 100 agreed to participate in the study (86% response rate). Sixty women (60%) were entirely compliant. While older patients (\u3e 40 years) were significantly less likely to show complete compliance (OR: 0.12; 950/ Cl: 0.02-0.58; p = 0.009)
The IARC perspective on cervical cancer screening
In May 2018, the World Health Organization (WHO) called for a global initiative to eliminate cervical cancer as a public health problem. To achieve this goal, global scale-up of effective vaccination against the human papillomavirus (HPV) as well as screening for and treatment of cervical cancer are required. Cervical cancer screening was evaluated in 2005 by the International Agency for Research on Cancer (IARC) Handbooks program,1 and a reevaluation was deemed to be timely given the major advances in the field since then. The new handbook provides updated evaluations of the effectiveness of screening methods, which were used as a basis for the update of the WHO Guideline for Screening and Treatment of Cervical Pre-cancer Lesions for Cervical Cancer Prevention.2 We convened an IARC Working Group of 27 scientists from 20 countries to assess the evidence on the current approaches to and technologies used in cervical cancer screening with the use of the newly updated Handbooks Preamble3 (Fig. 1) and Table 1).Fil: Bouvard, Véronique.

WITHDRAWN: Active versus expectant management in the third stage of labour.
BACKGROUND: Expectant management of the third stage of labour involves allowing the placenta to deliver spontaneously or aiding by gravity or nipple stimulation. Active management involves administration of a prophylactic oxytocic before delivery of the placenta, and usually early cord clamping and cutting, and controlled cord traction of the umbilical cord. OBJECTIVES: The objective of this review was to assess the effects of active versus expectant management on blood loss, post partum haemorrhage and other maternal and perinatal complications of the third stage of labour. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group trials register. SELECTION CRITERIA: Randomised trials comparing active and expectant management of the third stage of labour in women who were expecting a vaginal delivery. DATA COLLECTION AND ANALYSIS: Trial quality was assessed and data were extracted independently by the reviewers. MAIN RESULTS: Five studies were included. Four of the trials were of good quality. Compared to expectant management, active management (in the setting of a maternity hospital) was associated with the following reduced risks: maternal blood loss (weighted mean difference -79.33 millilitres, 95% confidence interval -94.29 to -64.37); post partum haemorrhage of more than 500 millilitres (relative risk 0.38, 95% confidence interval 0.32 to 0.46); prolonged third stage of labour (weighted mean difference -9.77 minutes, 95% confidence interval -10.00 to -9.53). Active management was associated with an increased risk of maternal nausea (relative risk 1.83, 95% confidence interval 1.51 to 2.23), vomiting and raised blood pressure (probably due to the use of ergometrine). No advantages or disadvantages were apparent for the baby. AUTHORS' CONCLUSIONS: Routine 'active management' is superior to 'expectant management' in terms of blood loss, post partum haemorrhage and other serious complications of the third stage of labour. Active management is, however, associated with an increased risk of unpleasant side effects (eg nausea and vomiting), and hypertension, where ergometrine is used. Active management should be the routine management of choice for women expecting to deliver a baby by vaginal delivery in a maternity hospital. The implications are less clear for other settings including domiciliary practice (in developing and industrialised countries)
Improved detection of high-grade cervical intra-epithelial neoplasia using Electrical Impedance Spectroscopy with colposcopy
A spectral phenotype of oncogenic human papillomavirus-infected exfoliative cervical cytology distinguishes women based on age
BACKGROUND: Human papillomavirus (HPV) is a sexually-transmitted infection associated with cervical cancer. Of over 100 HPV types identified, 13 are high-risk oncogenic. In unvaccinated women worldwide, the incidence of cervical cancer from HPV16 and HPV18 will remain. Cervical cytology can be graded from normal (atypia-free) to low-grade to high-grade. Infrared (IR) spectroscopy is a non-destructive technique that allows the acquisition of a biochemical-cell fingerprint based on vibrational states of chemical bonds. METHODS: Exfoliative cervical cytology specimens (n=147) were retrieved, graded by a cytologist and HPV-tested/genotyped using hybrid capture 2 and the Roche HPV Linear Array. Additionally, the spectral signatures of cervical cell lines C33A, HeLa and SiHa were examined. After washing, cellular material was transferred to low-E glass slides and interrogated using attenuated total reflection Fourier-transform IR (ATR-FTIR) spectroscopy. Given the complex nature of the dataset consisting of thousands of variables (wavenumbers), we used multivariate analysis for data reduction and information retrieval. Principal component analysis coupled with linear discriminant analysis (PCA-LDA) generated a visual representation of the data (scores plot) and, identification of the wavenumbers and consequent biochemical entities responsible for segregation (loadings plot). RESULTS: Immortalised cell lines were readily distinguishable from each other. It was difficult to segregate categories of cytology associated with HPV infection types. However, in low-grade cytology infected with high-risk oncogenic HPV16 or HPV18, it was possible to segregate women based on whether they were aged 20-29years vs. 30-39years. CONCLUSIONS: Our findings suggest a spectral phenotype in exfoliative cervical cytology associated with transient vs. persistent HPV infection
Clinical performance of the cobas 4800 HPV test
The clinical performance of the cobas human papillomavirus (HPV) test for detection of high-grade disease in a colposcopy-referred population was compared with that of Hybrid Capture 2 (HC2). The overall agreement between the tests was 92.3%. Clinical sensitivity and specificity for detection of cervical intraepithelial neoplasia grade 2 or greater (CIN2+) were 90.0% and 55.5% for cobas and 90.5% and 50.2% for HC2, respectively. In conclusion, both tests showed comparable performance for detection of CIN2+.Health Research BoardIrish Cancer SocietyFriends of the Coomb
