We sought to determine the efficacy of remaking initially unsatisfactory cervicovaginal ThinPrep (Cytyc, Boxborough, MA) specimens with and without the addition of glacial acetic acid (GAA) and the effect on human papilloma virus (HPV) Hybrid Capture II (HC2; Digene, Gaithersburg, MD) testing. A total of 583 initially unsatisfactory ThinPrep slide preparations were identified, and remakes were made with the residual in the PreservCyt (Cytyc) vials with (n = 455) or without (n = 128) GAA. Clinical follow-up information was obtained. The addition of GAA resulted in a 56.5% reduction in unsatisfactory cases, compared with a 26.6% reduction without GAA. Neoplasia and atypia were detected in the reprocessed specimens. The addition of GAA resulted in false-positive HC2 test results in 10 of 10 cases. Neutralization of the specimen may reverse this effect. Reprocessing unsatisfactory ThinPrep specimens with GAA can substantially reduce the overall unsatisfactory rate and result in the detection of significant lesions. However, the addition of GAA can result in false-positive results on HC2 HPV tests.
Interpreting biliary brush cytology (BBC) findings in primary sclerosing cholangitis (PSC) is problematic. In our study, BBC findings and CA19-9 serum levels were evaluated for their effectiveness in diagnosing cholangiocarcinoma in patients with PSC. We reviewed 107 biliary brushings from 51 patients with PSC and concurrent CA19-9 levels between January 1995 and March 2004 at the University of Washington Medical Center, Seattle. A portion of the brushings were evaluated and scored according to specific cytologic criteria; statistical analysis showed which criteria were most predictive in diagnosing malignancy: nuclear/cytoplasmic ratio, prominent nucleoli, nuclear membrane irregularities, and discohesion were significant predictive features. Sensitivity and specificity of BBC were 62.5% and 100%, respectively. Sensitivity and specificity of CA19-9 at a cutoff of 186 IU/mL were 100% and 94%, respectively. BBC is a specific and relatively sensitive method of detecting cholangiocarcinoma, even in patients with PSC, especially when certain cytomorphologic features are identified. Combining biliary cytology and CA19-9 levels might have an important diagnostic role in PSC.
To determine the effect of human immunodeficiency virus type 1 (HIV-1) infection upon pelvic inflammatory disease (PID), a laparoscopic study of acute PID was conducted in Nairobi, Kenya. Subjects underwent diagnostic laparoscopy, HIV-1 serology, and testing for sexually transmitted diseases. Of the 133 women with laparoscopically verified salpingitis, 52 (39%) were HIV-1-seropositive. Tubo-ovarian abscesses (TOA) were found in 33% of HIV-1-infected and 15% of HIV-1-uninfected women (odds ratio [OR], 2.8; 95% confidence interval [CI], 1.2-6.5). Among seropositive women, TOA was found in 55% of those with CD4 cell percent <14% vs. 28% with CD4 cell percent>14% (OR 3.1, 95% CI 0.6-15.3). Neisseria gonorrhoeae was detected in 37 women (28%) and Chlamydia trachomatis in 12 (9%); neither was significantly related to HIV-1 seropositivity. Length of hospitalization was not affected by HIV-1 serostatus overall but was prolonged among HIV-1-infected women with CD4 cell percent <14%. Among patients with acute salpingitis, likelihood of TOA was related to HIV-1 infection and advanced immunosuppression. In general, HIV-1-seropositive women with acute salpingitis responded well to treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
