    Title Loop Electrosurgical Excision Procedure and Risk of Preterm Birth.
    Date March 2010
    Journal Obstetrics and Gynecology

    To examine whether preterm birth is related to the loop electrosurgical excision procedure (LEEP) itself or intrinsic to the women undergoing the procedure.

    Title Comparison of Human Papilloma Virus Testing and Spectroscopy Combined with Cervical Cytology for the Detection of High-grade Cervical Neoplasia.
    Date May 2007
    Journal Journal of Lower Genital Tract Disease

    OBJECTIVE: This study compared the performance of cervical cytology plus human papilloma virus testing (Pap + HPV) or cervical spectroscopy (Pap + CS) for identifying high-grade cervical neoplasia in a high-risk population of women referred for colposcopy. MATERIALS AND METHODS: Each of 113 subjects underwent spectroscopy, thin-layer cytology, HPV testing, colposcopy, biopsy when indicated, and/or endocervical curettage. Evaluable data for analysis were collected for 102 of the subjects. Sensitivity and specificity were calculated for both strategies. RESULTS: Pap + HPV and Pap + CS achieved equivalent sensitivities (95%) for high-grade lesions, with both detecting 17 of 18 histology confirmed cervical intraepithelial neoplasia (CIN) 2+ lesions. Pap + HPV had a specificity of only 27.4% compared with 65.5% for Pap + CS (p < .0001). CONCLUSIONS: Spectroscopic interrogation of the cervix is equally sensitive and 2-fold more specific than HPV testing when combined with cervical cytology for identifying high-grade cervical neoplasia.

    Title A Case-control Study of Methylenetetrahydrofolate Reductase Polymorphisms in Cervical Carcinogenesis.
    Date June 2006
    Journal Gynecologic Oncology

    OBJECTIVES: Polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene are thought to be associated with a varying risk of cervical dysplasia. The purpose of this trial was to study the role of the two common functional MHTFR polymorphisms in a large multiracial population at risk for cervical dysplasia and cancer. METHODS: This is a nested case-control study of 376 subjects obtained from cohorts enrolled in an ongoing prospective cervical carcinogenesis protocol. Cases included invasive cancers (n = 51), and high (n = 50) and low (n = 50) grade dysplasia. There were 225 normal controls. Functional MTHFR 677C-->T and 1298A-->C genotypes were identified. Follow-up cytology data were reviewed for the control subjects from the time of study entry until August 2004. RESULTS: There is a significant racial difference in allele frequency of the 677C-->T polymorphism (P < 0.005). African-American women had an extremely low prevalence of the 677T allele (8%). There was no significant difference in the frequency of the 677T allele between cases and controls. There is no racial difference in allele frequency of the 1298A-->C polymorphism. Also, no significant difference was found between cases and controls. Of the 51 cancers, no case was homozygous for both aberrant polymorphisms (677T, 1298C), and only 3 cases were heterozygous for both. Follow-up data were available for 129 of 225 control subjects (57%). Only 15 (12%) have had a subsequent abnormal pap, and there was no association with the 677C-->T polymorphism. CONCLUSIONS: We confirm a significant difference in the 677T allele frequencies among racial groups. However, there is no association of either the 677C-->T or 1298A-->C polymorphisms in cervical carcinogenesis. There is no role of the combined polymorphism effect in cervical cancer or evidence of prediction for future Pap abnormalities.

    Title Vaginal Speculum Lubrication and Its Effects on Cervical Cytology and Microbiology.
    Date November 2005
    Journal Contraception

    The prevailing approach to Papanicolaou (Pap) and endocervical Gen-Probe(R) screening is to use an unlubricated vaginal speculum because of concerns that gel lubricant interferes with Pap smear adequacy and cervical microbiology. This study tests the hypothesis that lubrication of metal specula with a bacteriostatic gel does not increase unsatisfactory cervical cytology or decrease detection rates of endocervical Chlamydia trachomatis or Neisseria gonorrhoeae. At a publicly funded family planning clinic site, each of eight consecutive months was randomly designated by computer as an exclusively gel-lubricated or water-moistened specula use month. The assigned vaginal speculum intervention was used on all patients receiving a Pap smear and/or combination DNA probe assay for endocervical C. trachomatis and N. gonorrhoeae. From July 2003 through February 2004, 3460 Pap smears and 5535 combination probe assays for C. trachomatis and N. gonorrhoeae were collected from 6538 patients. During the 4 months of gel lubricant use, the rate of unsatisfactory cytology was 1.1% compared to 1.5% during the 4 months of water lubrication [odds ratio (OR) 0.74; 95% confidence interval (CI) 0.41-1.35]. During the 4 months of gel lubricant use, the detection rate for endocervical C. trachomatis was 1.5% compared to 1.5% (OR 1.05; 95% CI 0.67-1.62) in water lubricant months. The study population N. gonorrhoeae infection rate was too low to statistically analyze. The use of a small amount of gel lubricant on metal vaginal specula did not increase unsatisfactory cytology or decrease endocervical C. trachomatis detection rates when compared to water lubricant.

    Title Sexual Assault: a Report on Human Immunodeficiency Virus Postexposure Prophylaxis.
    Journal Obstetrics and Gynecology International

    The objective of this report is to describe an urban county hospital human immunodeficiency virus (HIV) infection prevention protocol offering prophylactic combination antiretroviral medications to female victims of sexual assault. A retrospective chart review was conducted from June, 2007 through June, 2008 of 151 women who were prescribed antiretroviral prophylaxis by protocol. All women receiving HIV prophylaxis initially screened HIV seronegative. Of the 58 women who reported taking any HIV prophylaxis, 36 (62%) were HIV screened at 12 and/or 24 weeks and none had HIV seroconverted. Although the initiation of an HIV post exposure prophylaxis protocol for sexual assault in a county hospital population is feasible, patient follow-up for counseling and HIV serostatus evaluation is an identified barrier.
