-soft chancre, ulcus molles—-
-haemophylus ducreyi (Gram-streptobacilus)
-multiple painful purulent vulvar papule and ulcers
-lymphadenopathy with abscess formation
-healing by fibrotisation
-they cause purulent inflammation of the LNs and Lymphatic vessels of vulva, so they have similar manifestations
₋ healed by fibrotisation and deform vulva and destroy the lymphal drainage–>
lymphostenosis
₋ so better treated in early stages
16
Q

mucous gland
bartholinitis is purulent inflammation
if not surgically treated, the blocked duct
(postinflammation stenosis) will keep the mucous
accumulated and form a cys

28
part of uterus
exocervic:
-part of cervix exposed to vagina
-stratified SQUAMOS epi
endocervix
-single layer tall COLUMNAr/GLANDULAR mucus secreting
- channel inside cervix
squamos columnar junctuin: junctional mucosa
29
what happens with vaginal epi durinng growing
glandular epi extend to surface of cervical channel=ectopy
next that happens is it meet acidic enviroment and will undergo squamos metaplasia =squamos epi
so the cells are changed into the squamous
epithelium again, which block the duct of the glands
mucous accumulate in the duct and becomes cyst=NABOTHIAN CYSTS
30
chronic cervicitis
-common
-asymp
- all STD, inf disorder form lower genital sys
Complications
1.ascendant spread-->PID-pelvic inflammatory disease
- bacteria spred up to endometrium, ovary, fallopian tube
2. tumorigenesis
3. development of endocervical polyps
4. pregnancy:a bortion, premature delievru
5. chorioamnitis. stillbirth
6. neonatal pneumonia/seoticaemi
7.postpartum endometritis
31
HOV of uteri

- signs: acanthosis(thick squamos epi)+papillomatosis(prolif of epi and intrude into dermis)+mitotic activity(+kilocytosis(nuclear enlargment, irr membrane, darker, clear area around(bc acc of glycogen) nucleus, (nuclei wdeformated:wrinkled, dense and small liker aisin)
=cytopathic effect
32
precancerosis of uterus cervic: cervical intraepo neoplasia-CIN
development of CIN I CIN II CIN III CIS-carcinoma in situ
caharcteristic for all grades:
dysplastic nucleo w irr outline, denser chromatin, distinct nucleoli, ^mitotic activity
grade 1:eneste LOW GRADE
- 1:3 third of lower squamos
-only base of epi is dyspalstic
mild lesion, not severe
grade 2:
-moderate
-in lower 2/3
-
grade 3:

33
risk factors of precancerosis of cervic uteri(CIN)
factors increasing the risk of HPV infection- early sexual life, multiple partners, promiscuity
of partners
long-term oral contraceptives- early first pregnancy, high parity- low socioeconomic status- other sexually transmitted disorders- smoking, diet, poor hygiene
34

39
layers of uterus
inner: endo
middle: myo-muscular wall
external: parametrium
40
metrorrhagia
- irr, frquent bleeding
- not assiated with menstrual cycle
-m
41
menorrhagia/hypermenorrhagia
excessive(prolonged menstruatuion
menoorhagia: prolonged menstruation
hyper: menstrual blededing is stornger and more intense
42
1st etiology for functional disorders are disturbances of
ovulation cycle
anovulatory cycle: Graafian follicle doesn’t rupture and release egg, but still produce estrogen (hyperplasia of endometrium)(no progesterone produced)
inadequate luteal phase: Graafian follicle ruptures, but the corpus leuteum is small and weak, not strong enough to produce adequate amount of progesterone
hypoprogesteronism, so again the problem of mucosal development and cause bleeding
irregular endometrium, in the patient at one time, we can see different stages (early, middle, late) of proliferative phase, or of secretory phase
mix endometrium: combination of proliferative +
secretive endometrium
43

3 ways of inflammation development in follapian tube
1. ascendant
-form lower genital sys
-microflora of vagina destroyed-->cervical channel dilated-->spread thorug
2. hematogenous
- TB
3. parametrial vv
- infection spread form vivinty by LN or blood
consequence of this spred is acut of chronic infla of fallopian tube=salpingitis
66
salpingitis-acute and chronci
acute:
-ascendant bacterial spreading-->PID
chrinic:
-from acute
-adhesions-sterility, extrauterine growth): fibrotization-->adhesions-->impermapble for eggg thorugh fallopian-->infertility and extrauterine gravidity
-
67
salpingitis -complications
1. Pyosalpinx:
- filled with pus
- plugging-->acite infla--clear fluod remain
3. tubo-ovarian abcess
- ovarian tube or ovary
- prevent spreaf of bacteria to abd cavity (Salpinc opens into abd)-->tube attach to surface of obary-->fusion--
68
acute salpingitis-micro

steps
1. dysreg of CNS:
-disturbance f prod of FSH
-^Lh ->dysreg of normal androgen secretion to ovary->^intraovarian androgen sti instead of estroegn->foliccular atresia, atrophy and hyperandrogenesia=> masculinsm of women(hair, alopecia, acne, hirsutism) or androgens chnages into estorgen(both hyperandrogen and estorgen
Bilaterally enlarged and cystic ovaries – excessive production of androgens, low levels of female hormons
