1 Female Genital System infection
2017/4/24

2 Natural defenses of genital tract
Vulva Inherent resistance to infection Fungicidal Proper apposition of introitus by of labia Vagina Close apposition of vaginal wall Well developed stratified squamous epithelium Vaginal flora Vaginal acidity

3 Contd.. Cervix Uterus Tubes Functional closure of cervix
Thick mucus plug Immune –abundance of plasma cell in sub epithelial layer and high concentration of cytotoxic T cell Uterus Periodic shedding of surface endometrium during menses Tubes Peristalsis movement

4 Contents Vulvovaginal infection Cervicitis
Pelvic inflammatory disease (PID) 2017/4/24

5 Section 1 Vulvovaginal infection
Vulvitis Bartholinitis/Bartholin’s cyst Trichomonas vaginitis Candidiasis Bacterial vaginosis Atrophic vaginitis 2017/4/24

6 Self-cleaning Thicken vaginal epithelium Resistance↑
Result in large quantities of glycogen in epithelial cells Kill or inhibit pathogens Lactobacilli Produce H2O2 Lactic acid production↑ Acid environment ( ) Promote growth of normal vaginal flora 2017/4/24

7 Bartholinitis/Bartholin’s cyst
2017/4/24

8 Anatomy of Bartholin’s glands
Position: the base of each bulb Opening Secretion: viscid, clear and stringy 2017/4/24

9 2017/4/24

10 Etiology Infection Congenital narrowing of duct
Obstruction of main duct of bartholin Retention of secretions and cystic dilatation 2017/4/24

11 Clinical findings Bartholinitis Bartholin’s cyst Pain Tenderness
Dyspareunia Surrounding tissues become edematous and inflamed Fluctuant, tender mass Bartholin’s cyst No system Fluctuant mass can be palpable 2017/4/24

12 Clinical findings 2017/4/24

13 Treatment Drain the abscess
Marsupialization for preservation of the gland function Antibiotics (Ampicillin) in the early stage Excision for recurrent cases or postmenopausal patient 2017/4/24

14 Trichomonas vaginitis
2017/4/24

15 Etiology Trichomonad A flagellate protozoan Best living environment
Moist Anaerobic pH: 2017/4/24

16 Pathogenesis The trichomonad lives on glycogen and iron of the host cell Direct contact and damage of the target cell Arose immune reaction resulting in inflammation 2017/4/24

17 Transmission Sexual contact (70% male infection, asymptomatic carrier)
Nonsexual transmission Iatrogenic Contact-soap 2017/4/24

18 Clinical findings latent period: 4-28 days Asymptomatic: 25-50%
Symptoms Main: Profuse vaginal discharge thin,creamy orslightly green in colour irritating and frothy.and pruritus ,inflamation of vulva. Occasional: odor, pain, dyspareunia, dysuria, infertility. Signs Multiple small putate Strawberry spot on vagina and cervix. Tiny, punctuate hemorrhages on the mucosa 2017/4/24

19 Characteristics of the vaginal discharge 
Profuse Purulent Gray to yellow color Malodorous Frothy Anaerobic glycolysis 2017/4/24

20 2017/4/24

21 Diagnosis Microscopic identification of trichomonad (60%-70%)
Precautions for the examination Avoid Intercourse 1-2 days before examination Washing and medication Lubricant Heat preservation Culture for suspected cases Refractory case 2017/4/24

22 Treatment Systemic therapy : Oral metronidazole
2g single dose 400mg, twice or 3 times a day, for 7 days Side effect Topical application (≤50%) Effervescent tablets of metronidazole 200mg/day, 7-10 days Acidify vagina with 1% lactic acid or 0.5% acetic acid 2017/4/24

23 Treatment Criterion for cure: Negative finding in postmenstrual examination of vaginal discharge for three times Failure rate: 5%-10% Poor compliance Repeated infection To avoid repeated infection Sterilize underwear, towels, etc Treat the sexual partner Metronidazole 2017/4/24

24 Candidiasis 2017/4/24

25 Etiology Very common The etiologic agent is Candida
About 1/3 of vaginitis cases are caused by fungal infection About 75% of women develop candidiasis at least once in life The etiologic agent is Candida Candida albicans is responsible for 80-90% of VVC. 2017/4/24

26 Etiology Candida albicans is an opportunistic pathogen
Suitable environment: acid (<4.5), warm, and moist Can be isolated from 10-20% Nonpregnant and 30% pregnant women (asymptomatic) Treatment is not indicated unless symptoms are present 2017/4/24

27 Pathogenesis Yeast spores (Asymptomatic parasitism)
Two phases of candida albicans Proper environment Pseudohypha (Pathogenic) Penetrate vaginal epithelium for nutrients Release proteolytic enzymes and toxins etc Result in inflammatory reaction 2017/4/24

28 Predisposing factors Pregnancy DM Immunosuppressant
Broad-spectrum antibiotics: suppress the vaginal normal flora (esp. lactobacillus) Others Restrictive synthetic underwear Obesity Contraceptive medication 2017/4/24

29 Transmission Endogenous infection (most often) Sexual contact
Vagina, oral cavity, intestinal tract Sexual contact Contact fomites 2017/4/24

30 Clinical findings Vulvovaginal pruritus (main) Vaginal discharge↑
Usually intense, coincident with menses or intercourse Vaginal discharge↑ white, thick, curd-like discharge, forming patches adhere to vaginal walls Vulvar erythema Systems may worse just prior to menses 2017/4/24

31 Diagnosis Microscopic identification of candida albicans
Saline: 30-50% 10% KOH: 70-80% Gram’s stain: 80% Culture: higher sensitivity and drug test Measurement of pH value pH<4.5 simple infection pH>4.5 combined infection 2017/4/24

32 Treatment Only for symptomatic patients.
Eliminate predisposing factors Control DM Discontinue complicating medications Long-term, regular, multiple topical therapy Treatment of sexual partner Asymptomatic: No treatment 15% should be treated 2017/4/24

33 Treatment Topical application of antifungal agents Miconazole
200mg/day for 7days 400mg/day for 3 days Clotrimazole ( cream) 150mg/day for 7 days 150mg, twice a day for 3 days 500mg single dose Nystatin: 500,000 units/day for days 2017/4/24

34 Treatment Fluconazole: 150mg, single use. Itraconazole
Systemic medication: for cases who can’t be treated with topical application of antifungal drugs Fluconazole: 150mg, single use. Itraconazole 200mg/day for 3-5 days 400mg for 1 day divided in two doses Ketoconazole: 200mg, once or twice/day until culture result is negative 2017/4/24

35 Points of note for treating VVC
Treatment should be followed-up with a premenstrual examination of vaginal discharge Approximately 10% of cases will not respond to initial therapy→prolong treatment up to 14 days Identify and eliminate predisposing factors RVVC (5%)should be treated with oral therapy followed by prophylactic doses 2017/4/24

36 Bacterial Vaginosis 2017/4/24

37 Etiology Imbalance of normal vaginal flora
Lactobacilli is decreased Other bacteria are increased (anaerobic bacteria—Gardnerella) Causative factors of the imbalance are unknown Vaginal douching Frequent sexual relationship 2017/4/24

38 Clinical findings Signs Systems
Asymptomatic: 10-40% Mild pruritus or burning sensation Increased vaginal discharge and fishy odor Signs Discharge: fishy, gray-white, homogenous, but not sticky No inflammation 2017/4/24

39 Diagnosis Identification of clue cells *together with 2 of the following 3 items Vaginal discharge: homogenous, thin and white pH>4.5: in virtually all cases ( ) Positive Whiff test (with 10% KOH) 2017/4/24

40 Clinical pictures Clue cells: Desquamated epithelial cells covered with clumps of coccobacili especially Gardnerella vaginalis→ gives the cells a speckled appearance 2017/4/24

41 Treatment Antibiotics Systemic therapy (oral) Topical therapy
Metronidazole: 400mg, 2-3 times a day for 7d Clindamycin : 300mg, twice a day for 7d Topical therapy Effervescent tablets of metronidazole: 200mg/day, for 7-10 days 2% Clindamycin cream, once a day for 7 days 2017/4/24

42 Criteria for cure Absence of clue cells with at least 1 of the following items Normal vaginal discharge pH≤4.5 Whiff test 2017/4/24

43 Points of note for treating BV
Systemic or topical treatment has the same cure rate (80%). Patients who are asymptomatic, but scheduled to have a gynecologic surgical procedure should be treated. Patients who are pregnant can be treated with oral metronidazole. Follow-up examination should be given after the treatment (postmenstrual) 2017/4/24

44 Differential diagnosis of vaginitis
Trichomonias Candidiasis BV Complaints discharge↑ mild pruritus severe pruritus burning Vaginal discharge thin , purulent frothy white curd-like White, fishy homogenous Vaginal epithelium punctuated hemorrhage edema erythematic normal Vaginal pH >5 ( ) <4.5 >4.5 ( ) Whiff test - + Microscopic examination Trichomonad WBC many Candida WBC some Clue cells WBC rare 2017/4/24

45 Atrophic vaginitis 2017/4/24

46 Etiology Ovarian function decreaseE Vaginal mucosa is thin
PH of vagina is abnormal high → Normally acidogenic flora are replaced by mixed flora Vaginal epithelium is more susceptible to infection and trauma 2017/4/24

47 Clinical findings Symptoms Signs Vaginal discharge↑ Vulvar itching
Dyspareunia Signs Vaginal mucosa is thin ,vaginal folds are few or absent Spotting hemorrhage 2017/4/24

48 Treatment Intravaginal application of E cream Intravaginal antibiotics
1/3 of vaginal E is systemically absorbed Contraindication: women with a history of breast or endometrial cancer E tablet intravaginally daily for two weeks twice per week for at least 3-6 months Intravaginal antibiotics 2017/4/24

49 Cervicitis Section2 2017/4/24
