Genital Tract Infections

If you want to give your Obstetrics and Gynaecology preparation a quick boost, then read this blog post on Genital Tract Infections! 

The burden of untreated infections is especially high for women because sometimes these infections are asymptomatic or in other cases the symptoms are not recognizable. But not anymore because we have outlined everything you need to know in the paragraphs below!

Let’s learn more about Genital Tract Infections, a critical topic for your OBGYN preparation.

Asherman Syndrome 

Etiology

• Overzealous Curettage done For
  • AUB (Abnormal Uterine bleeding),
  • MTP
  • Secondary PPH [d/t retained bits of Placenta]
  • Such curettage injures basal lamina causing scarring & Fibrosis of endometrium [no further gland development]. This then leads to secondary amenorrhea.
• Endometrial TB also causes Asherman Syndrome

Treatment

• Hysteroscopic Adhesiolysis
• Followed with High dose Estrogens & Progesterone: for cyclical withdrawal

Tubercular PID

• Incidence → 20-25% of women in India

Pathogenesis

• Endometritis Menorrhagia [Initially]
  ↓
  Endometrial destruction
  ↓
  Asherman Syndrome→ Oligomenorrhea
  Hypomenorrhea 
  Amenorrhea [mc]
• Fallopian Tube
  • Calcific, beaded, rigid tube
  • Hydrosalpinx: Tobacco Pouch Hydrosalpinx
  • Retort Shaped Hydrosalpinx

Treatment

• 4 Drugs for 2 months & 3 Drugs for 4 months
• Do not stop the Rx in 1^st trimester

Pelvic Inflammatory Disease 

Causes

• Chamydia: Most prevalent; Indolent
• Gonorrhea: Most common in OPD
• Mycoplasma
• TB
• Ureaplasma
• Bacteroids
• Pepto streptococcus
• Bacterial vaginosis [important cause]
• Streptococcus

Clinical Features 

Symptoms

• Pain abdomen
• Congestive dysmenorrhea
• Dysparunia
• Fever 

Signs

• Fever
  • Admit IF
    • Temp > 38°C/ 100.4°F
    • Severe Symptoms
    • Suspicious Pelvic Abscess
    • Unreliable/ Non Compliant Patient
    • Uncertain Diagnosis
• ↑ CRP
• Leucocytosis
• On P/v
  • cervical motion tenderness
  • Uterine tenderness
  • Adnexal tenderness

Additional Criteria

• Culture & Sensitivity Of
  • Endometrial Biopsy
  • Vaginal swab
  • Cervical Swab
  • Culture Medias For
    • Gonorrhea: Thayer martin media
    • Chlamydia: Mc coy cell lines [PCR Preferred]
• ↑ ESR/ CRP
• ↑ TLC
• Fever > 100.4°F [38°C]

Elaborate Criteria

• Diagnostic Laparoscopy
  • Gives direct evidence
  • Laparoscopy “IF DONE” is the best way to diagnose PID
• USG: Documents pelvic/tuboovarian abscess

Discharge Criteria: Temperature < 99.5°F

Treatment

• Centre for disease control of atlanta In patient regimes
  • Out patient regimes
• Broad Spectrum Antibiotics

OPD Regime

• Cefoxitine 2gm iv or Cefotaxime 1gm iv
• Doxycycline 100 gm BD x 14 Days: For chlamydia
• Metronidazole 500 mg BD x 14 Days
  • For anaerobes
  • For bacterial vaginosis
• Azithromycin can be given instead of Doxycycline
• Clindamycin can be given instead of Metronidazole

Vaginitis

• Ph of Vagina
• Candidiasis → can occur in acidic ph of 4.5
• Bacterial vaginosis can occur in Alkaline PH
• Trichomoniasis Alkalinity Shift also predisposes [5.5 or 6...]

Amsel’s Criteria

• Useful in Dx of Bacterial vaginosis
• ≥ 3 out of 4 are required
  • Creamy discharge
  • Whiff Test ⊕
  • Fishy odour
  • Clue Cells

Bacterial Vaginosis can cause

• PID
• Relapse of PID
• Chorioamnionitis [PID in pregnancy]
  • Abortion
  • IU Death
  • Puerperal sepsis
• Vault cellulitis
• Whiff test can also be positive in trichomoniasis
  • As both Bacterial vaginosis & Trichomoniasis CO-Exists
  • Classical For Bacterial vaginosis
• Rx the male partner also in Trichomoniasis
• Rx the male partner also in candidiasis
• Rx only women in B Vaginosis (as not STTD)

Q. Which of the following is the drug of choice for bacterial vaginosis in pregnancy? 

• Metronidazole
• Clindamycin

• 100
• 80
• 60
• 50

Q. 18 year old girl comes to gynae OPD presenting with 6 months of amenorrhea, with h/o low grade fever, weight loss, pain abdomen, generalized weakness. On examination pelvic mass felt on left side with features of ascites. Diagnosis? 

• TB pelvis with tubo ovarian mass
• Ectopic pregnancy
• Granulosa cell tumour
• Fibroid degeneration
