Abstract

This study aims to determine the diagnostic values of visual inspection with acetic acid (VIA) and Pap smear in a cervical cancer screening program at a community level in Vietnam. A cross-sectional analysis was obtained, including 1034 women of reproductive age from Thua Thien Hue Province, Vietnam from 09/2012 to 09/2013. Samples were taken from cervixes for Pap smear testing, followed by visual inspection with acetic acid. Subjects with abnormal VIA and/or positive cytology results were invited for colposcopy and biopsy. Histologic confirmed cervical intraepithelial neoplasia (CIN2+) served as gold standards for diagnostic values analysis. Abnormal VIA results were recorded in 87 cases (7.7%). The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of VIA for CIN2+ were 88.8%, 43.8%, 63.4%, 51.2% and 83.3%, respectively. Diagnostic values of Pap smear were 58.0%, 85.2%, 69.9%, 83.3% and 61.3% for its sensitivity, specificity, accuracy, PPV and NPV, respectively. VIA yielded high sensitivity but its accuracy is still limited in pre-cancerous lesions during cervical cancer screening. The Pap smear has acceptable sensitivity and specificity, but its false-negative rate is still high. We recommend a combination of different tests to increase the efficiency of screening in our community., Highlights • VIA has high sensitivity in pre-cancerous lesions and cervical cancer screening. • The sensitivity and specificity of Pap smear are acceptable. • Pap smear for triage after VIA(+) could increase the efficiency.

Abstract

Pteropine orthoreovirus, potentially of bat origin, has been reported to cause respiratory tract infections among human beings in Southeast Asia. Twelve IgG ELISA-positive cases with antibodies against Pteropine orthoreovirus were detected among 272 human serum samples collected between March and June 2014 from in and around Hue City, Central Vietnam. These 12 cases were IgM ELISA negative. Neutralizing antibodies were also detected among six of these cases with the highest titer of 1:1,280 in 2 cases (both female, 32 and 68 years old, respectively). This is the first report of human infection with Pteropine orthoreovirus in Central Vietnam. These findings indicate the need for surveillance on Pteropine orthoreovirus infections in Southeast Asia to enable prevention and control strategies to be developed should a change in virulence occur.

Abstract

Objective:To determine the relationship between a Chlamydia trachomatisPCR positive diagnosis from cervical canal swabs and the presence of tubal diseases among infertile women in Vietnam.Methods:In this cross-sectional descriptive study, women who sought infertility treatment at the Center for Reproductive Endocrinology & Infertility, Hue University Hospital, Vietnam, from June 2016 to June 2017 were enrolled. All study participants were interviewed, and PCR tests were then performed to diagnose Chlamydiafrom cervical canal swabs. Hysterosalpingogram (HSG) was carried out to examine the uterine cavity and fallopian tubes.Results:Among 568 women whose mean age was 32.0 ± 5.1 years, the prevalence of C. trachomatisinfection as detected by PCR was 5.8%. Eighty-one percent (460/568) of infertile women had normal HSG results, and abnormal HSG results were more frequent in women over 35 years old, in women with secondary infertility, and in those with a history of miscarriage or genital tract infection. However, there was no relationship between C. trachomatisPCR positivity and HSG results in infertile women.Conclusions:The diagnosis of C. trachomatisinfection using the cervical swabs is the useful but not an effective method for routine practice for predicting tubal obstruction in infertile women.
