Gynecological Disorders Practice Questions

Q: Regarding bacterial vaginosis, all are true except?

Presence of WBCs in 50% of cases. **Explanation:** Bacterial Vaginosis (BV) is a clinical syndrome resulting from the replacement of normal hydrogen peroxide-producing *Lactobacillus* species with high concentrations of anaerobic bacteria (e.g., *Gardnerella vaginalis*, *Mobiluncus*, and *Atopobium vaginae*). **Why Option C is the Correct Answer (The False Statement):** Bacterial Vaginosis is characterized by a **lack of vaginal inflammation**. Therefore, the presence of White Blood Cells (WBCs/pus cells) on a saline wet mount is notably **absent**. If significant numbers of WBCs are seen, a co-infection (like Trichomoniasis or Cervicitis) should be suspected. **Analysis of Other Options:** * **Option A:** In BV, the loss of Lactobacilli leads to a rise in vaginal pH. A **pH > 4.5** (typically 5.0–6.0) is a diagnostic criterion. The discharge is characteristically thin, white, and homogeneous. * **Option B:** The **Whiff Test** is positive when 10% KOH is added to the discharge, releasing volatile amines (putrescine and cadaverine) that produce a "fishy" odor. * **Option D:** While BV is polymicrobial, ***Gardnerella vaginalis*** is the most common organism isolated and plays a central role in biofilm formation. **High-Yield Clinical Pearls for NEET-PG:** * **Amsel’s Criteria (3 out of 4 required):** 1. Homogeneous thin white discharge. 2. Vaginal pH > 4.5. 3. Positive Whiff test. 4. **Clue Cells** on microscopy (most specific finding). * **Nugent Scoring:** The "Gold Standard" for diagnosis (based on Gram stain morphotypes). * **Treatment:** Drug of choice is **Metronidazole** (500 mg BID for 7 days). Treatment of the male partner is **not** recommended.

Q: What is the treatment of choice for extragenital endometriosis?

Complete excision. **Explanation:** **Extragenital endometriosis** refers to the presence of endometrial-like tissue outside the pelvic cavity (e.g., in the lungs, bowel, bladder, or surgical scars). The treatment of choice is **Complete Excision (Option A)**. Unlike pelvic endometriosis, which often responds to hormonal suppression, extragenital implants are frequently fibrotic and less responsive to medical therapy. Surgical removal is the only definitive way to eliminate the ectopic tissue, confirm the diagnosis histologically, and prevent recurrence or complications (such as bowel obstruction or catamenial pneumothorax). **Why other options are incorrect:** * **Medical treatment only (Option B):** Hormonal therapy (GnRH agonists, OCPs, or Progestins) may provide temporary symptomatic relief by inducing atrophy of the implants, but it is rarely curative. Once the medication is stopped, symptoms typically recur. * **Medical plus surgical treatment (Option C):** While sometimes used for extensive pelvic disease, surgery remains the primary modality for extragenital sites. Medical therapy is generally considered secondary or adjuvant. * **Steroids (Option D):** Steroids have no role in the management of endometriosis; they do not address the underlying hormonal dependency of the tissue. **High-Yield Clinical Pearls for NEET-PG:** * **Most common site of extragenital endometriosis:** The **Bowel** (specifically the rectosigmoid), followed by the bladder. * **Scar Endometriosis:** Most commonly occurs after a **Cesarean section**; presents as a painful, palpable lump that increases in size and pain during menstruation. * **Catamenial Pneumothorax:** Recurrent lung collapse occurring within 72 hours of menstruation; it is the most common presentation of thoracic endometriosis. * **Gold Standard Diagnosis:** Laparoscopy with biopsy (Visual confirmation + Histopathology).

Q: All of the following are features of müllerian agenesis except?

Ovarian agenesis. **Müllerian Agenesis**, also known as **Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome**, is a congenital anomaly characterized by the failure of the Müllerian ducts to develop. This results in the absence or hypoplasia of the uterus, fallopian tubes, and the upper two-thirds of the vagina. ### Explanation of Options: * **Ovarian agenesis (Correct Answer):** In MRKH syndrome, the ovaries develop from the **primitive germ cells** (not the Müllerian ducts). Therefore, ovarian function is entirely normal. Patients have normal estrogen levels, leading to normal secondary sexual characteristics. * **46, XX karyotype:** These patients are genotypically and phenotypically female. A 46, XX karyotype distinguishes MRKH from Androgen Insensitivity Syndrome (46, XY). * **Normal breast development:** Since the ovaries are functional and produce estrogen, the hypothalamic-pituitary-ovarian axis is intact. This leads to normal breast development (Thelarche) and pubic hair growth (Adrenarche). * **Absent vagina:** The Müllerian ducts form the upper 2/3rd of the vagina. Their failure to develop results in a "vaginal dimple" or a shortened, blind-ending vaginal pouch. ### High-Yield Clinical Pearls for NEET-PG: * **Presentation:** Most common cause of **primary amenorrhea** with normal secondary sexual characteristics (second only to Turner Syndrome). * **Associated Anomalies:** 30-40% of cases have **Renal anomalies** (e.g., renal agenesis, ectopic kidney) and 10-15% have **Skeletal anomalies** (e.g., Klippel-Feil syndrome). * **Diagnosis:** Gold standard is **MRI** to visualize pelvic structures; Ultrasound is the initial screening tool. * **Treatment:** Non-surgical vaginal dilation (Frank’s method) is the first-line treatment to create a functional vagina. Surgical options include McIndoe vaginoplasty.

Q: Colposcopy can visualize all structures EXCEPT:

Endometrium. **Explanation:** The correct answer is **Endometrium**. **Why Endometrium is the Correct Answer:** Colposcopy is a diagnostic procedure that uses a specialized binocular microscope (colposcope) to provide a magnified view of the **lower genital tract epithelium**. The colposcope is an external instrument; it does not enter the uterine cavity. Since the endometrium is the internal lining of the uterine corpus, it remains inaccessible to the colposcope. Visualization of the endometrium requires **Hysteroscopy**, which involves inserting an endoscope through the cervical canal into the uterine cavity. **Why the Other Options are Incorrect:** * **Cervix:** This is the primary indication for colposcopy. It is used to evaluate the Transformation Zone (TZ) and identify abnormal vascular patterns or acetowhite changes suggestive of CIN (Cervical Intraepithelial Neoplasia). * **Vagina:** When the vagina is examined under magnification, the procedure is specifically termed **Vaginoscopy**. It is used to detect VAIN (Vaginal Intraepithelial Neoplasia). * **Vulva:** Magnified examination of the vulvar skin is termed **Vulvoscopy**, used to identify areas of VIN (Vulvar Intraepithelial Neoplasia) or lichen sclerosus that require biopsy. **High-Yield Clinical Pearls for NEET-PG:** * **Magnification:** A colposcope typically provides 6x to 40x magnification. * **Key Solutions:** 3–5% **Acetic Acid** (causes reversible protein coagulation in dysplastic cells, appearing as "acetowhite" areas) and **Lugol’s Iodine** (Schiller’s test; normal cells turn mahogany brown, while abnormal cells remain pale/yellow). * **Green Filter:** Used to enhance the visualization of abnormal vascular patterns like **punctations, mosaicism, and atypical vessels** (suggestive of malignancy). * **Indication:** The most common indication is an abnormal Pap smear (e.g., LSIL, HSIL).

Q: Which of the following is a contraindication for dilatation and curettage?

Acute pelvic inflammatory disease. **Explanation:** **Dilatation and Curettage (D&C)** is a common gynecological procedure used for both diagnostic and therapeutic purposes. However, it is strictly contraindicated in certain clinical scenarios to prevent severe complications. **Why Acute Pelvic Inflammatory Disease (PID) is the correct answer:** In the presence of **Acute PID**, the pelvic organs are highly inflamed, friable, and often harbor virulent pathogens. Performing a D&C during the acute phase can lead to the **dissemination of infection** into the peritoneal cavity or the bloodstream, potentially causing generalized peritonitis, pelvic abscess formation, or septicemia. Furthermore, the risk of uterine perforation is significantly increased due to the softened, inflamed myometrium. **Analysis of Incorrect Options:** * **Tuberculous Endometrium:** D&C is actually a **diagnostic tool** here. Histopathological examination of the endometrium (looking for granulomas) is essential for confirming genital tuberculosis. * **Post-menopausal Bleeding:** This is a **primary indication** for D&C. It is mandatory to rule out endometrial hyperplasia or malignancy in any patient presenting with bleeding after menopause. * **Endometrial Carcinoma:** While fractional curettage is being replaced by office biopsies (like Pipelle), D&C remains a standard method for obtaining tissue for **diagnosis and staging** of endometrial cancer. **High-Yield Clinical Pearls for NEET-PG:** * **Absolute Contraindications for D&C:** Acute PID and viable intrauterine pregnancy (unless performing an MTP). * **Fractional Curettage:** This is the specific technique used when malignancy is suspected; the endocervical canal is sampled *before* the uterine cavity to determine the extent of the disease. * **Complications:** The most common immediate complication of D&C is **uterine perforation**, while the most common late complication is **Asherman Syndrome** (intrauterine adhesions).

Q: All of the following are reasons for the sudden onset of pain in an asymptomatic case of uterine fibroid, EXCEPT?

Hyaline degeneration. **Explanation:** Uterine fibroids (leiomyomas) are typically asymptomatic or present with chronic symptoms like menorrhagia. Sudden, acute pain in a fibroid indicates a complication. **Why Hyaline Degeneration is the Correct Answer:** Hyaline degeneration is the **most common** type of fibroid degeneration (occurring in ~65% of cases). It is a **chronic, slow process** where smooth muscle is replaced by homogenous hyaline tissue due to a gradual decrease in blood supply. Because it is a slow, progressive replacement rather than an acute event, it does **not** cause sudden pain. **Why the other options are incorrect (Reasons for Acute Pain):** * **Torsion:** Occurs in pedunculated subserous fibroids. The twisting of the pedicle leads to acute ischemia and venous congestion, causing sudden, severe abdominal pain (an emergency). * **Infection:** Usually occurs post-delivery or post-abortion (especially in submucous fibroids). It leads to acute inflammation, fever, and sharp pain. * **Red Degeneration (Necrobiosis):** Most common during the **second trimester of pregnancy**. It is caused by rapid growth leading to venous obstruction and infarction. It presents with sudden, localized pain, tenderness, and low-grade fever. **Clinical Pearls for NEET-PG:** * **Most common degeneration overall:** Hyaline degeneration. * **Most common degeneration in pregnancy:** Red degeneration. * **Degeneration with highest malignant potential:** None (Cystic/Calcareous are benign), but **Sarcomatous transformation** (<0.5%) is the malignant change (usually post-menopausal). * **Calcific (Calcareous) degeneration:** Most common in post-menopausal women (womb stone).

Q: Which of the following factors is not an important risk factor for tubal ectopic pregnancy?

Intrauterine device (IUD) use. **Explanation:** The correct answer is **B. Intrauterine device (IUD) use.** While it is a common misconception that IUDs cause ectopic pregnancies, they are actually highly effective contraceptives that significantly reduce the **absolute risk** of any pregnancy, including ectopic ones. However, if a woman *does* become pregnant with an IUD in situ, the **relative risk** (proportion) of that pregnancy being ectopic is higher. Because the question asks for an "important risk factor," IUD use is the outlier; it is a protective factor against pregnancy in general. **Analysis of other options:** * **A. History of tubal surgery:** This is the **strongest risk factor** for ectopic pregnancy (highest Odds Ratio). Procedures like tubal ligation or re-anastomosis cause structural damage and scarring, hindering the transport of the fertilized ovum. * **C. In utero DES exposure:** Diethylstilbestrol exposure in utero is associated with structural uterine anomalies (T-shaped uterus) and fallopian tube abnormalities (ciliary dysfunction), which significantly increase ectopic risk. * **D. History of Pelvic Inflammatory Disease (PID):** PID (often due to *Chlamydia trachomatis*) causes salpingitis, leading to the loss of endosalpingeal cilia and the formation of intratubal adhesions (plicae), which trap the embryo. **High-Yield Clinical Pearls for NEET-PG:** * **Most common site of ectopic pregnancy:** Ampulla of the Fallopian tube (70-80%). * **Most common site of rupture:** Isthmus (occurs early, around 6-8 weeks). * **Classic Triad:** Amenorrhea, abdominal pain, and vaginal bleeding (present in only 50% of cases). * **Arias-Stella Reaction:** Hypersecretory endometrium seen on biopsy; it is suggestive of pregnancy but not specific to ectopic pregnancy.

Q: Which of the following is NOT true about genital infection in bacterial vaginosis?

Pruritus is seen. **Explanation:** Bacterial Vaginosis (BV) is a clinical syndrome characterized by a shift in the vaginal flora from dominant *Lactobacillus* species to an overgrowth of anaerobic bacteria (e.g., *Gardnerella vaginalis*, *Mobiluncus*, and *Prevotella*). **Why "Pruritus is seen" is the correct answer (NOT true):** Pruritus (itching) and vaginal inflammation are typically **absent** in Bacterial Vaginosis. BV is a non-inflammatory condition (hence "vaginosis" rather than "vaginitis"). If a patient presents with significant pruritus and erythema, clinicians should suspect *Candidiasis* or *Trichomoniasis* instead. **Analysis of other options:** * **Clue cells are present:** These are vaginal epithelial cells coated with coccobacilli, giving them a "stippled" or "shaggy" appearance. They are the most specific diagnostic criterion for BV. * **Gardnerella is the causative agent:** While BV is polymicrobial, *Gardnerella vaginalis* is the hallmark organism associated with the condition. * **Grey and foul-smelling discharge:** A thin, homogenous, milky-white or grey discharge with a "fishy" odor (due to the release of amines) is a classic clinical feature. **NEET-PG High-Yield Pearls (Amsel’s Criteria):** To diagnose BV, 3 out of 4 of the following must be present: 1. **Homogenous discharge** (thin, white/grey). 2. **Vaginal pH > 4.5** (Most sensitive). 3. **Positive Whiff Test:** Fishy odor on adding 10% KOH. 4. **Clue Cells** on wet mount (Most specific). * **Gold Standard Diagnosis:** Nugent Scoring (Gram stain). * **Treatment of Choice:** Oral or topical Metronidazole (safe in pregnancy).
