Cervical Disorders (Exam One) Flashcards
What is the area where the cells of the vagina (squamous cells) and the cells of the uterus ( columnar or glandular cells) meet?
Transformation zone
True / False - The SCJ (squamocolumnar junction) is static and remains in the same position from the cervix / vagina throughout the woman’s life
False- the SCJ moves as a result of hormonal and environmental influences (such as pregnancy)
Endocervix is lined with columnar cells and ectocervix are completely lined with squamous epithelium during what ?
Premenarchal sturcture
Post menarche SCJ is generally found where
Ectocervix - with increased eversion during pregnancy
post menopause the SCJ is often found where?
Within the endocervical canal
The naming system that Pap smears utilize
Bethesda System
Naming of cell types with Bethesda system ASC-USASC- HLSILHSIL
ASC-US: Atypical squamous cells of undetermined significanceASC-H- Atypical squamous cells in which High-grade lesions cannot be excludedLSIL- Low-grade squamous intraepithelial lesion(cellular change consistaent with CIN I ) HSIL - High-grade squamous intraepithelial lesion- Includes cellular changes consistent with CIN II and CIN III
How are Biopsied lesions of the cervix classified
with CIN nomenclature
CIN nomenclature Cervical Intraepithelial Neoplasia (CIN) CIN I CIN IICIN III Cancer in situ (CIS)
CIN I - Disordered growth of the lower third of the epithelial lining (mild dysplasia) CIN II- Abnormal maturation of the lower 2/3 of the epithelial thickness( Moderate dysplasia) CIN III- Involves more than 2/3 of the epithelial thickness (severe dysplasia) Cancer In Situ (CIS) - involves full thickness of the epithelium
what layer is broken through by abnormal cells to begin evading other tissue and create what we know as cancer
Basement membrane
Abnormal cells iwth mild changes at the surface
Low-grade changes
What is the Peak prevalence in women of Cervical Dysplasia
25-35 y.o. females
What are the two big factors that are included in Epidemiology of Cervical dysplasia
SES - socioeconomic status and geographic location
What are some risk factors for women for increased Cervical Dysplasia
Smoking, HPVHPV i fond in more than 80% of the CIN lesions Others: Multiple sexual partners, Genital neoplasia, HIV/AIDS, immunosuppression, multiparous, Long term oral contraceptive pill user, High-risk sexual partners, lower genital neoplasia, hx of exposure ot cervical neoplasia
HPV - currently _____ americans are currently infected
79 million
approximately _____ million people will become infected with HPV each year (in America)
14 million
women have what percentage chance of infection of HPV throughout lifetime
50-80% chance
Percentage of immunocompetent women that will resolve HPV infection within ____ years
90% 2 years
there are 130 types of HPV of which 30-40 will infect the ano-genital tissue Types ___, X5 will cause genital warts and low grade lesions
types 6 11424344
Which types (X13) of HPV are linked to CIN II and III and cancer
types16, 18, 31, 33, 39, 45, 51, 56, 58, 59, 68
what percentage is condom usage at decreasing spread of HPV . Why is this still insignificant to protect form HPV
60% effectiveThe condoms do not protect against labial-scrotal transmission
What are the prevention (medicine) tools for HPV
GardasilGardasil-9 and Cervarix
DDX for HPV
CervicitisPelvic Inflammatory DiseaseVaginitis TrichomoniasisHerpes LesionAbnormal Cells on Pap from surrounding tissue
Clinical features of Cervical Dysplasia
Often aysmptomatic visible cervical lesionFriable cervixbleeds easily-post coital bleeding
