Differences in cervical cytologic and histologic findings between women using depot-medroxyprogesterone acetate and oral contraceptives.
Summary of "Differences in cervical cytologic and histologic findings between women using depot-medroxyprogesterone acetate and oral contraceptives."
OBJECTIVE.: This study aimed to compare cervical cytologic and histologic findings between women using depot-medroxyprogesterone acetate (DMPA) and oral contraceptives (OCs) referred for colposcopy and to determine whether there were differences in the occurrence of false-positive cytologic finding between the 2 contraceptive groups. MATERIALS AND METHODS.: Retrospective cohort of 1,569 premenopausal women using either DMPA or OC who were evaluated for abnormal cervical cytologic findings. Cytologic and histologic data were collected in conjunction with routine gynecologic examinations or follow-up colposcopic evaluations. χ tests were used to determine differences in cervical cytologic and histologic findings and the proportion of false-positive results across contraceptive groups. Nominal logistic regression was used to evaluate the association between contraceptive use, cervical, and histologic abnormalities while controlling or age and smoking status. RESULTS.: The mean age of all participants was 23.5 years, with no significant difference between OC (n = 1194) and DMPA (n = 375) users. Although there were no differences in the proportion of false-positive cytologic results (21.8% overall), DMPA users were more likely to smoke (p < .001), have atypical glandular cell (AGC) on referral cytology (p < .001), and have histologic confirmation of cervical intraepithelial neoplasia 2, 3 (p = .004). Users of DMPA remained more likely to have AGC cytology after considering smoking status; however, cervical intraepithelial neoplasia 2, 3 was found to be associated with smoking status and not use of DMPA. CONCLUSIONS.: We found no difference in the proportion of false-positive cytologic results between DMPA and OC users referred for evaluation of abnormal cytology. Users of DMPA were more likely to have AGC, which necessitates a more comprehensive evaluation.

Medical and Biotech [MESH] Definitions
The technique of using FIXATIVES in the preparation of cytologic, histologic, or pathologic specimens for the purpose of maintaining the existing form and structure of all the constituent elements.
A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.
Cervical Length Measurement
A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.
The first cervical vertebra.

Large cell neuroendocrine carcinoma (LCNEC) of the uterine cervix is a rare tumor. Moreover, there are only three reports to date that have focused on the cytologic findings of cervical LCNEC. We repo...
PURPOSE: Diagnosis of cervical neoplasia hinges upon microscopic inspection of cervical samples. This has inherent operator-dependent variability. Testing for high-risk human papilloma virus (HPV) may...
Background: Ectopic cervical thymomas are rare and there are few descriptions of the cytologic findings based on fine needle aspiration. Their appearances can be misinterpreted as either benign or mal...

OBJECTIVE: To investigate the natural course of low-grade squamous intraepithelial lesions (LSILs) that cannot be histologically confirmed by colposcopy-directed biopsy. METHODS: In a multicenter, pro...
