Gynecological Disorders Practice Questions

Q: Which of the following drugs is commonly used in the treatment of endometriosis?

Combined oral contraceptives. ***Combined oral contraceptives*** - **Combined oral contraceptives (COCs)** are the **most commonly used first-line medical treatment** for endometriosis, as they suppress ovulation and reduce estrogen production, thereby reducing endometrial lesion growth. - They help manage **endometriosis-associated pain** by decreasing menstrual flow and uterine contractions. - COCs are widely prescribed due to their efficacy, safety profile, and additional contraceptive benefits. *Letrozole* - **Letrozole** is an aromatase inhibitor that reduces local estrogen production and has shown efficacy in treating endometriosis, particularly in refractory cases. - However, it is **not commonly used as first-line therapy** due to potential side effects (bone density concerns, teratogenicity) and is typically reserved for cases resistant to conventional hormonal therapy. - It may be used in combination with progestins for better outcomes. *Mifepristone* - **Mifepristone** is an antiprogestin primarily used for medical abortion or in the treatment of Cushing's syndrome. - It works by blocking **progesterone receptors** and is not a standard treatment for endometriosis. *None of the above* - This option is incorrect because **combined oral contraceptives** are the most widely accepted and commonly used treatment for endometriosis.

Q: Which of the following ovarian tumors is most prone to undergo torsion during pregnancy?

Dermoid cyst. ***Dermoid cyst*** - **Dermoid cysts**, or mature cystic teratomas, are the **most common ovarian tumors** to undergo torsion, especially during pregnancy due to their mobility and moderate size. - They are often **unilateral** and benign, containing various mature tissues such as hair, teeth, and sebaceous material. *Serous cystadenoma* - While common, **serous cystadenomas** are generally **less mobile** than dermoid cysts and thus have a lower propensity for torsion. - They are typically filled with **clear, watery fluid** and can grow to be quite large. *Mucinous cystadenoma* - **Mucinous cystadenomas** tend to be **larger** than dermoid cysts and are less prone to torsion due to their size and often fixed position within the pelvis. - They are filled with **thick, gelatinous mucin** and can reach massive sizes, sometimes filling the entire abdominal cavity. *Theca lutein cyst* - **Theca lutein cysts** are usually **bilateral** and occur with conditions like **gestational trophoblastic disease** or **ovarian hyperstimulation**. - While they can be large, their often bilateral nature and underlying pathological conditions make them **less likely to independently twist** as a primary event compared to a freely mobile dermoid cyst.

Q: In MRKH syndrome, which of the following structures is typically absent?

Uterus. ***Uterus*** - **Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome** is characterized by congenital aplasia of the **uterus** and upper two-thirds of the vagina. - This is due to abnormal development of the **Müllerian ducts**, which are embryonic structures that form the uterus, fallopian tubes, cervix, and upper vagina. *Breast development* - **Breast development** is typically normal in MRKH syndrome as it is influenced by ovarian hormones, and the **ovaries are usually functional** in these individuals. - Normal breast development indicates that the **estrogen production** from the ovaries is intact. *Pubic hair development* - **Pubic hair development** is also normal in MRKH syndrome, as it is a secondary sexual characteristic driven by **adrenal androgens** and ovarian hormones, which are generally not affected. - The presence of pubic hair indicates **normal adrenal and ovarian androgen production**. *Testes* - **Testes** are male gonads and are therefore not present in individuals with MRKH syndrome, as these patients are **genetically female (46,XX karyotype)**. - The absence of testes is a normal finding in females, and thus not a characteristic feature or absence due to MRKH syndrome itself.

Q: Which of the following is not a standard treatment option for CIN III?

Wertheim's hysterectomy. ***Wertheim's hysterectomy*** - A **Wertheim's hysterectomy**, also known as a **radical hysterectomy**, involves removal of the uterus, cervix, parametrium, and upper vagina, along with pelvic lymph node dissection. This is typically reserved for **invasive cervical cancer**, not CIN III. - While hysterectomy can be a treatment option for CIN III in specific circumstances (e.g., patient preference, coexisting uterine pathology), a Wertheim's hysterectomy is an **overly aggressive procedure** for precancerous lesions due to its significant morbidity. *LLETZ* - **Large Loop Excision of the Transformation Zone (LLETZ)**, also known as LEEP (Loop Electrosurgical Excision Procedure), is a common and effective outpatient treatment for CIN III. - It involves using a heated wire loop to **excise the abnormal tissue** from the cervix, allowing for histological examination. *Conization* - **Cold knife conization** involves excising a cone-shaped piece of tissue from the cervix using a scalpel. This method is highly effective for CIN III. - It provides **excellent pathological specimens** for evaluation of margins, which is crucial for confirming complete removal of the lesion. *Hysterectomy* - **Hysterectomy** (removal of the uterus, usually simple hysterectomy) can be considered a treatment option for CIN III, particularly in women who have completed childbearing and have other indications for hysterectomy, or when repeated excisional procedures have failed. - While effective, it is a more **invasive procedure** than LLETZ or conization and generally reserved for specific cases where conservative management is not suitable or desired.

Q: Which of the following conditions is most commonly associated with malodorous vaginal discharge?

Bacterial vaginosis. ***Bacterial vaginosis*** - This condition is characterized by a "fishy" or **malodorous vaginal discharge**, particularly noticeable after intercourse due to the release of amines. - It results from an imbalance in the vaginal flora, with an overgrowth of anaerobic bacteria and a decrease in protective lactobacilli. *Chlamydia trachomatis* - Often presents with **asymptomatic cervicitis** or mild watery discharge; **malodorous discharge** is not a common or prominent symptom. - While it can cause pelvic pain or dysuria, it's not typically associated with the characteristic smell of bacterial vaginosis. *Trichomonas vaginalis* - Can cause a **frothy, yellow-green discharge** that may be malodorous, but the "fishy" odor is more classically associated with bacterial vaginosis. - Other common symptoms include intense itching, burning, and dyspareunia. *Neisseria gonorrhoeae* - Causes cervicitis, which can lead to a **purulent or mucopurulent vaginal discharge**, but it does not typically produce the distinctive malodor seen in bacterial vaginosis. - Infection can also manifest as dysuria, pelvic pain, or be asymptomatic.

Q: What condition is diagnosed using the Amsel criteria?

Bacterial vaginosis. ***Bacterial vaginosis*** - The **Amsel criteria** are specifically used for the clinical diagnosis of **bacterial vaginosis (BV)**. - The criteria include the presence of at least three of four findings: **homogeneous discharge**, **vaginal pH >4.5**, **positive whiff test**, and **clue cells** on microscopy. *Antiphospholipid antibody syndrome* - This syndrome is diagnosed based on **clinical criteria** (thrombosis, pregnancy morbidity) and the presence of persistent **antiphospholipid antibodies** (lupus anticoagulant, anti-cardiolipin, anti-β2-glycoprotein I antibodies). - It does not involve the use of the Amsel criteria. *Ovarian ectopic pregnancy* - Diagnosed primarily through **ultrasound imaging** showing a gestational sac or fetal heartbeat within the ovary, often accompanied by clinical symptoms like abdominal pain and vaginal bleeding. - This condition is not related to vaginal infections or the Amsel criteria. *HELLP Syndrome* - **HELLP syndrome** (Hemolysis, Elevated Liver enzymes, Low Platelets) is a severe obstetric complication usually occurring in pregnancy, diagnosed by **laboratory findings** of these specific abnormalities. - It is a systemic condition, not a vaginal infection, and does not use the Amsel criteria for diagnosis.

Q: Which of the following precancerous conditions, if treated, has the highest likelihood of not leading to cancer?

Cervical intraepithelial Neoplasia. ***Cervical intraepithelial neoplasia (CIN)*** - CIN has a high success rate with treatment (e.g., **cryotherapy**, **LEEP**), often completely eradicating the dysplastic cells and preventing progression to **invasive cervical cancer**. - The effectiveness of screening via **Pap smears** allows for early detection and intervention, significantly reducing cancer risk. *Ductal carcinoma in situ (DCIS) of breast* - While treatable, DCIS carries a higher risk of recurrence and progression to **invasive breast cancer** in the same or contralateral breast compared to CIN. - Treatment often involves **lumpectomy** with or without radiation, and sometimes **total mastectomy**, reflecting its more serious potential. *Lobular carcinoma in situ (LCIS) of breast* - LCIS is largely considered a **risk indicator** for future invasive cancer in either breast, rather than a direct precursor that inevitably progresses. - Management often involves **close surveillance** or **chemoprevention**, as surgical excision does not prevent cancer development in other areas of the breast. *Vaginal intraepithelial neoplasia (VAIN)* - While treatable, VAIN is less common and often coexists with or follows **cervical or vulvar neoplasia**, indicating a broader field defect due to **HPV**. - Recurrence rates post-treatment can be significant, and patients often require long-term follow-up due to the continued risk of progression.

Q: Most common complication of dermoid cyst is -

Torsion. ***Torsion*** - Ovarian dermoid cysts (mature cystic teratomas) are prone to **torsion** due to their common unilateral, round, and easily mobile nature. - Torsion results from the **twisting of the ovarian pedicle**, which can lead to exquisite pain and potential **ischemic necrosis** of the ovary. - **Most common complication** occurring in **15-20% of dermoid cysts**. *Cyst Rupture* - While rupture can occur, it is a **less common complication** than torsion, occurring in **1-4% of cases**. - Rupture can release sebaceous material and hair into the peritoneal cavity, leading to **chemical peritonitis**. *Malignant degeneration* - **Malignant transformation** within a dermoid cyst is rare, occurring in **less than 1-2% of cases**, making it much less common than torsion. - The most common type of malignancy arising from a dermoid cyst is **squamous cell carcinoma**. *Infection* - **Secondary infection** of dermoid cysts is a rare complication. - Much less common than torsion, and typically presents with fever, pain, and signs of inflammation.
