PAPANICOLAU METHOD (PAP'S SMEAR) Flashcards
______________ is the SECOND BEST CHOICE for routine cytologic examination, AFTER PAPANICOLAU with a greater possibility for immediate microscopic examination used for hormonal evaluation of gynecologic specimen and for cancer detection
PHASE-CONTRASTE MICROSCOPY
APPLICATIONS OF PAPANICOLAU METHOD (PAP’S SMEAR)
- SCREEN CERVICAL CANCER
- To determine the cause of certain infection
- Hormonal cytology
- Medico-legal examination of sexual assault
PAP SMEAR PROCEDURE PREPARATION
- PATIENT SHOULD ABSTAIN FROM COITUS
- Do not douche the vagina for at least a day
- Do not apply intravaginal preparations for at least one week before the examination
- SMEARS SHOULD NOT BE TAKEN DURING MENSTRUAL BLEEDING, because contamination with blood, endometrial and tissue debris can obscure the cells in examination
Pap smear should be done at least _____ days after the last menstrual period
at least 10 DAYS AFTER THE LAST MENSTRUAL PERIOD
STAINS FOR PAP’S SMEAR:
- Harris hematoxylin
- Orange green 6 (OG-6) stain
- Eosin Azure 50 (EA-50) stain
Pap smear stain that stains the NUCLEUS:
Harris hematoxylin
Pap smear stain that stains the CYTOPLASM OF MATURE CELL and stains KERATIN
ORANGE GREEN 6 (OG-6) stain
Pap smear stain that sta8ins the CYTOPLASM OF IMMATURE CELL
EOSIN AZURE 50 (EA-50) stain
COMPONENTS OF EA-50 STAIN:
- Light green SF
- Bismarck brown Y
- Eosin Y
- Phosphotungstic acid
- Lithium carbonate
Stains the CYTOPLASM OF OTHER CELLS, including non-keratinized squamous cells.
LIGHT GREEN SF
STAINS NOTHING and in contemporary formulants it is often omitted
Bismarck Brown Y
Stains the superficial epithelial squamous cells, nucleoli, cilia, and red blood cells
EOSIN Y
This method provides OPTIMUM NUCLEAR DETAIL information, which is important for cytologic evaluation of PAP’s smears, non-gynecological and FNA cytologic specimens
MODIFIED PAPANICOLAU STAIN
In Modified Papanicolau stain, to produce a more distinct color differentiation:
BISMARCK BROWN IS OMOTED from the EA 50 formula
Routine Pap’s procedure staining time
FIRST STAIN:
FIRST STAIN:
Stain in Harri’s hematoxylin, 5 minutes
Routine Pap’s procedure staining time
SECOND STAIN:
SECOND STAIN:
Stain in OG-6, 2 minutes
OG-6 is the FIRST COUNTERSTAIN in PAP’s smear
Routine Pap’s procedure staining time
THIRD STAIN:
THIRD STAIN:
EA-50 is the SECOND COUNTERSTAIN in PAP’s smear
PAP’S SMEAR STAINING REACTION:
Nucleus:
CYTOPLASM, Keratinizing cells:
CYTOPLASM, Non-keratinizing cells:
NUCLEUS: BLUE or BLACK
CYTOPLASM, Keratinizing cells: PINK or ORANGE
CYTOPLASM, Non-keratinizing cells: BLUE or GREEN
For vaginal hormonal cytology, smears are best taken from the __________________________ because it is more accessible and less likely to be contaminated by cellular debris and vaginal discharge
UPPER LATERAL THIRD OF VAGINAL WALL
Estrogen effect:
Progesterone effect:
Estrogen effect: INCREASED SUPERFICIAL CELLS
E—->S
Progesterone effect: INCREASED INTERMEDIATE CELLS
P—->I
In hormonal cytology, slide is checked under the ________________ to assess the quality of the smear and staining; quantitative evaluation is done using the ______
Hormonal cytology:
LPO: Quality
HPO: Quantity
Different cytologic samples:
- Upper lateral third of the vaginal wall
- Ectocervix
- Endocervix
Cytologic sample ideal for vaginal HORMONAL STATUS:
UPPER LATERAL THIRD OF THE VAGINAL WALL
MOST COMMON SITE FOR CANCER SCREENING because this is where malignancies arise
ECTOCERVIX
