Background: Atypical squamous cells of undetermined significance (ASCUS) remain the center of diagnostic controversy and patients’ stress despite recent advances in cervical cancer screening and the introduction of human papilloma virus (HPV) testing. The role of infectious agents in the induction of such changes is not well understood. Aim: We aim at reviewing the effect of the different infectious organisms in Papanicolaou (PAP) smears on the ASCUS diagnosis. Material: 133 ASCUS cases associated with variable infectious organisms (ASCUS-infection group) with secondary HPV testing and appropriate follow-up studies were reviewed. A control group of 310 ASCUS cases without any organisms (ASCUS-only group) was selected for comparison. Results: The ASCUS-infection group had a significantly higher proportion of HPV-positive tests than the ASCUS-only group (p = 0.0027). There was no significant difference on follow-up PAPs and biopsies between the two groups (p = 0.4272). They showed an overall mean of 75% negative, 20% low-grade lesions, and 5% high-grade lesions/carcinoma in situ on follow-up. Conclusion: Our study demonstrates no significant effect of infections on the cytological changes diagnostic of ASCUS. The cytologist should make this diagnosis neglecting any background infections even when predominant.
The purpose of the present study was to assess the findings in cervical smears associated with intramuscular depot medroxyprogesterone acetate (Depo-Provera) contraception. Seventy-four cervical smears of reproductive-age patients on Depo-Provera were reviewed for cytologic abnormalities, predominant cell type, and intermediate cell glycogenation (extensive (EGly) ϭ navicular cells / glycogenation in 10 or more high-powered fields (hpf); moderate (MGly) ϭ 5-10 hpf; and focal (FGly) ϭ less than 5 hpf). A control group of 38 nonpregnant patients without hormonal therapy was reviewed. Study group patients' (SGP) age ranged from 16 -44 years (average 28.1); control group patients (CGP) from 17-42 years (average 29.4). Time since last menstrual period (LMP) for the SGP was 16.9 months (range 1-96); LMP for CGP was 18.2 days (range 5-33). Four (5.4%) SGP had squamous intraepithelial lesions (SIL), four (5.4%) atypical squamous cells of undetermined significance (ASCUS), and one (1.4%) atypical repair. No CGP had SIL or ASCUS. Seventy-three (98.6%) SGP had intermediate cell (IC) predominance; one had parabasal cell predominance. Of the CGP, 28 (73.7%) had IC predominance, nine (23.7%) superficial cell (SC) predominance and one (2.6%) had near equal IC and SC. EGly was seen in 22 (29.7%) SGP; two (5.3%) in CGP (chi-square 7.53; 0.95 ϭ 3.84). MGly was seen in 29 (39.2%) SGP; 10 (26.3%) in CG. FGly was seen in 17 (22.9%) SGP; 14 (36.8%) in CGP. No glycogenation was seen in six (8.1%) SGP; 12 (31.6%) in CGP. Time since LMP was inversely proportional to glycogenation in SGP: EGly-LMP 11.6 months; MGly-LMP 14.9 months; FGly-LMP 15.0 months; and no glycogenation-LMP 22.5 months. Glycogenation of IC appears inversely proportional to Depo-Provera effect. EGly due to recent Depo-Provera administration mimics changes associated with pregnancy.
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.
