62. Diseases of vulva and vagina Flashcards

(48 cards)

Q

what is the normal physiology of and microbiology of the vagina?

A

THE NEWBORN`S VAGINAL EPITHELIUM IS STRONGLY ESTROGENIZED AND RICH IN GLYCOGEN, OF LACTIC ACID-PRODUCING LACTOBACILLI. THIS RESULTS IN A LOW PH (≤ 4.7), WHICH PROMOTES FURTHER GROWTH OF ACIDOPHILIC- PROTECTIVE MICROFLORA.

WITHIN DAYS OF BIRTH, ESTROGEN DECREASES, AND THE VAGINAL EPITHELIUM BECOMES THIN, ATROPHIC, AND LARGELY DEVOID OF GLYCOGEN. IN THIS ENVIRONMENT, THE PH RISES. AS A CONSEQUENCE, THE PREDOMINANT VAGINAL MICROFLORA BECOMES DIVERSE GRAM-POSITIVE COCCI AND BACILLI

THE ONSET OF PUBERTY AND OVARIAN STEROIDOGENESIS, THE VAGINA AGAIN BECOMES ESTROGENIZED, AND THE GLYCOGEN CONTENT INCREASES. LACTIC ACID-AND HYDROGEN PEROXIDE (H2O2) – PRODUCING LACTOBACILLI AGAIN PREDOMINATE, RESULTING IN SELF-SUSTAINING VAGINAL PH OF BETWEEN 3.8 AND 4.5.

Q

what can alter the protective vaginal flora

A

ANTIBIOTICS

spraying WITH WATER OR NONBUFFERED SOLUTIONS MAY TRANSIENTLY ALTER THE PH

SEXUAL INTERCOURSE WITH INTRODUCTION OF SEMEN RAISES THE PH TO 7.2 FOR 6 TO 8 HOURS, MAKING THE VAGINA RECEPTIVE TO STI PATHOGENS

THE PRESENCE OF A FOREIGN BODY (FORGOTTEN DIAPHRAGM OR TAMPON IN ADULTS OR VARIOUS SMALL OBJECTS IN CHILDREN) DRAMATICALLY DISRUPTS NORMAL VAGINAL CLEANSING MECHANISMS AND MAY LEAD TO SECONDARY INFECTION

Q

how do we diagnose bacterial vaginosis ?

A

a profuse , milky , discharge
amine or fishy odour after alkalisation with a drop of KOH (positive whiff test)

ph of the vagina goes more alkaline going over 4.5

vaginal wall normal

wet mound microscopy
clue cells - epithelia cells with bacteria attached to them - they are found from the vaginal discharge and sodium chloride is added and put under microscope

25
what is the diagnosis of atrophic vaginitis ?
indication lower estrogen levels: little pubic hair, loss of the labial fat pad, thinning and resorption of the labia minora, narrowing of the vaginal opening. Pale, smooth or shiny vaginal epithelium; loss of elasticity or turgor of skin; internal exam will reveal the presence of low vaginal muscle tone, the lining of the vagina appears smooth, shiny, pale with loss of folds. the ph is higher than 4.5 serum oestrogen levels cytological examinations of vaginal smear / papanicolaou of vagina immature basal cells and increased proportion of parabasal cells replacicing superficial epithelial cells which are diminishing
26
what is the treatment for atrophic vaginitis ?
topical estrogen | vaginal moisturisers
27
what is the cause of foreign body vaginitis ?
sexual abuse forgotten or lost tampons condoms
28
how is genital herpes transmitted ?
genital herpes - HSV 2 sexually
29
what is the complication of genital herpes in pregnancy ? and no in pregnancy ?
high risk at first trim increase fetal mortality- miscarriage PROM cause microcephaly , microopthalmia , if occurs in second trim - not bad ? go into labour less than 6 weeks after a first episode of genital herpes, your immune system won’t have had time to produce antibodies to protect your baby. There is thus a high chance of passing the virus to your baby if you have a vaginal CNS disease Meningoencephalitis (manifesting with fever, lethargy, irritability) Skin, eye, and mouth disease Vesicular skin lesions trouble breathing -grunting, blue appearance (cyanosis), rapid breathing short periods of no breathing dessimentaed - sepsis jaundice ========= there is reoccurrence as it resides in the nerve ganglion until it is triggered again
30
what is the signs and symptoms of genital herpes simplex?
can appear on the vulva, perineum, buttocks, anal area, cervix, and inside of the vagin Most patients are asymptomatic multiple , bilateral , painful red bumps or white vesicles the vesicles can burst to ulcerate unusual vaginal discharge pruritus Painful lymphadenopathy in the groin area fever myalgia Recurrence is common.
31
diagnosis of genital herpes simplex ?
Light microscopy findings on a Tzanck smear does not differentiate from hsv1 and 2 and vriella zzoter virus PCR viral culture specific serum antibodies
32
what is the treatment for genital herpes ?
there is no cure but symptomatic treatment and prevention of reoccurrence with acyclovir
33
what are the symptoms of HPV16 and 18 (31/33)?
90 parent of cases no symtoms and resolves spontaneously but in some HPV persists and presents as warts (mostly vulva , cervix and anus) precancerous lesions but transmission to fetus is rare
34
nearly all cervical cancer is caused by ?
HPV16 and 18
35
what is the prevention of HPV 16 and 18 ?
gardasil - HPV like particle vaccine
36
what is the treatment of HPV ?
should not be used in pregnancy : doctor applied medication - podophylin resin patient applied medication -podofilox cryotherapy , surgical , laser ablation excision
37
what is is vulvitis ?
inflammation of the vulva including - labio maoris and minors ,introits
38
different vulval diseases ?
``` PYOGENIC all caused by staph areas pyogenic - vulval cellulitis folliculitis ``` ====== viral genital herpes Condylomata accuminata ===== bartholinitis - Escherichia coli, Staphylococcus, Streptococcus bartholin cyst
39
describe the clinical manifestation of the pyogenic vulva infection
vulval cellulitis - limited, in majority, upto the labiocrural fold. The vulva is swollen, red, and tender. purulent discharge dysuria pruitis
40
treatmnet of pyogenic vulval infections ?
vulval cellulitis- systemic antibiotics local hot compress analgesics folliculitis / furunculosis -furunculosis -bath containing potassium permanganate loca and systemic antibiotics
41
clinical feature of bartholinitits
local pain and discomfort even to the extent of difficulty in walking or sitting. tenderness and induration of the posterior half of the labia when palpated between thumb outside and the index finger inside the vagina purulent secretion from duct pain during intercourse The infection may resolute completely or an abscess is formed. In others, the infection subsides only to recur in future. In such cases, the gland becomes fibrotic. Too often, the duct lumen heals by fibrosis with closure of the orifice → pent up secretion of the gland → formation of bartholin cyst
42
treatment for bartholinitis ?
Hot compress area and analgesics to relieve pain are instituted. Systemic antibiotic like ampicillin if abcess -Abscess should be drained at the earliest opportunity
43
treatment for bartholin cyst ?
Marsupialization is the An incision is made on the inner aspect of the labium minus just outside the hymenal ring includes the vaginal wall and the cyst wall. The cut margins of the either side are to be trimmed off to make the opening an elliptical shape The edges of the vaginal and cyst wall are sutured by interrupted catgut - free drainage
44
what causes genital warts or condyloma acuminate ?
Human Papilloma Virus (HPV) usually type 6 and 11 sexually transmitted

clinical signs and symptoms of condyloma accuminata
multiple papillary lesion grow in clusters along a narrow stalk giving it a cauliflower appearance anogenital HPV infection is: Cervix 70%, Vulva 25%, Vagina 10%
46
treatment of condyloma accuminata
local cytostatic treatment (e.g., 5-FU, trichloroacetic acid, podophyllin, or immune response modifiers (e.g., imiquimod, interferon alpha) Cryotherapy: freezing external warts with CO2, N2O, or N2 In case of numerous warts: curettage, laser surgery, or electrocoagulation ``` preventive HPV vaccine (Types 6 and 11) can prevent ```
47
treatment of bacterial vaginosis ?
internal gel that regulates the vaginal ph back to normal | metronidazole gel / clindamycin cream
48
vulvovaginal candiasis ?
