Question 1361: What is the most common presenting feature of a complete mole?
- A. Vomiting
- B. Hyperemesis gravidarum
- C. Amenorrhoea
- D. Bleeding per vaginum (Correct Answer)
Explanation: ***Bleeding per vaginum (Correct)*** - **Vaginal bleeding** in the first or early second trimester is the **most common presenting symptom** of a complete hydatidiform mole, occurring in approximately 80-90% of cases - This bleeding can vary in amount and color, often described as **prune juice-like** discharge with passage of grape-like vesicles in some cases - Typically presents between **6-16 weeks of gestation** as the most frequent initial clinical sign *Vomiting (Incorrect)* - While nausea and vomiting are common in normal pregnancies, this is **not the most common presenting feature** of a complete mole - Vomiting may occur but is less specific and typically occurs after or in conjunction with vaginal bleeding - When severe, it manifests as hyperemesis gravidarum (a separate entity) *Hyperemesis gravidarum (Incorrect)* - This condition, characterized by **severe, persistent nausea and vomiting**, is more prevalent in molar pregnancies due to **excessively high hCG levels** - Occurs in approximately **25-30% of complete moles**, making it a significant but not the most common presentation - It is a **consequence** of the molar pregnancy, often presenting **after** initial bleeding, and is not the most frequent first clinical sign *Amenorrhoea (Incorrect)* - **Amenorrhoea** (absence of menstruation) is a **universal symptom** of any pregnancy, including a molar pregnancy - While it indicates conception, it does **not differentiate** a molar pregnancy from a normal pregnancy or other causes of amenorrhoea - Therefore, it is not the most specific or common **presenting feature** that would lead to diagnosis of a molar pregnancy
Question 1362: What is the first-line treatment for simple hyperplasia of the endometrium?
- A. Endometrial ablation (surgical procedure)
- B. Estrogen therapy (e.g., Estradiol)
- C. Total abdominal hysterectomy (surgical removal of the uterus)
- D. Progestin therapy (e.g., Medroxyprogesterone acetate) (Correct Answer)
Explanation: ***Progestin therapy (e.g., Medroxyprogesterone acetate)*** - **Progestin therapy** is the first-line treatment for simple endometrial hyperplasia because it counteracts the unopposed estrogen effect causing the hyperplasia. - **Progestins** lead to endometrial atrophy and shedding, helping to reverse the hyperplastic changes and prevent progression to cancer. *Estrogen therapy (e.g., Estradiol)* - **Estrogen therapy** without concomitant progestins would exacerbate endometrial hyperplasia by further stimulating endometrial growth. - This treatment is contraindicated in cases of endometrial hyperplasia unless carefully balanced with progestins. *Endometrial ablation (surgical procedure)* - **Endometrial ablation** is a destructive procedure to remove the endometrial lining and is typically considered for persistent abnormal uterine bleeding, not as a primary treatment for simple hyperplasia. - It is often reserved for patients who have completed childbearing and fail medical management. *Total abdominal hysterectomy (surgical removal of the uterus)* - A **total abdominal hysterectomy** is an invasive surgical procedure that is generally reserved for complex or atypical endometrial hyperplasia, or hyperplasia that is recurrent and unresponsive to medical management. - It is not the first-line treatment for simple hyperplasia, especially in patients who may desire future fertility or wish to avoid major surgery.
Question 1363: Most common presentation of cervical cancer is -
- A. Abnormal vaginal bleeding (Correct Answer)
- B. Pelvic pain
- C. Pain during intercourse
- D. Unusual vaginal discharge
Explanation: ***Abnormal vaginal bleeding*** - **Abnormal vaginal bleeding** is the most frequent presenting symptom of cervical cancer, often manifesting as **postcoital bleeding**, intermenstrual bleeding, or heavier, longer menstrual periods. - This symptom arises as the tumor on the cervix ulcerates and bleeds due to its friable nature and rich vascularization. *Pelvic pain* - **Pelvic pain** is typically a symptom of more **advanced cervical cancer**, indicating tumor invasion into surrounding tissues or nerves. - It is not usually an early or the most common presenting symptom, unlike abnormal bleeding. *Pain during intercourse* - **Pain during intercourse (dyspareunia)** can be a symptom of cervical cancer, particularly with larger lesions or those causing inflammation. - However, it is less common than abnormal bleeding and often occurs concurrently with or after the onset of bleeding symptoms. *Unusual vaginal discharge* - An **unusual vaginal discharge**, which may be watery, foul-smelling, or blood-tinged, can occur with cervical cancer. - While a common symptom, it is generally considered less frequent than abnormal vaginal bleeding as the primary presenting complaint.
Question 1364: A patient presents with bilateral ovarian carcinoma, capsule involvement, ascites, and paraaortic lymphadenopathy. What is the appropriate stage of the disease?
- A. Stage 1C
- B. Stage 3C (Correct Answer)
- C. Stage 2C
- D. Stage 4C
Explanation: ***Stage 3C*** - **Bilateral ovarian carcinoma** with **capsule involvement**, **ascites**, and especially **paraaortic lymph node metastases** are defining features of Stage IIIC ovarian cancer. - Involvement of **retroperitoneal lymph nodes**, including paraaortic nodes, automatically upstages the disease to Stage III, irrespective of other abdominal spread. *Stage 1C* - This stage refers to ovarian cancer confined to **one or both ovaries**, with evidence of rupture, capsule involvement, or malignant cells in ascites/peritoneal washings, but **without lymph node involvement**. - The presence of **paraaortic lymphadenopathy** in this patient immediately excludes Stage 1C. *Stage 2C* - Stage 2 ovarian cancer involves one or both ovaries with **pelvic extension** beyond the ovaries, but still **without lymph node involvement**. - The patient's involvement of **paraaortic lymph nodes** goes beyond pelvic extension and therefore excludes Stage 2C. *Stage 4C* - Stage 4 ovarian carcinoma involves **distant metastasis** beyond the peritoneal cavity or distant lymph nodes (e.g., pleural effusion with positive cytology, parenchymal liver/spleen metastasis). - While paraaortic lymphadenopathy indicates advanced disease, it falls within the criteria for Stage 3 due to its location, not Stage 4.
Question 1365: Which of the following statements about radical hysterectomy in stage Ib cervical cancer compared to radiotherapy is false?
- A. Chance of recurrence is lower with radical hysterectomy.
- B. Ovarian function can be preserved.
- C. Chance of survival is higher with radical hysterectomy.
- D. It is less complicated than radiotherapy. (Correct Answer)
Explanation: ***It is less complicated than radiotherapy.*** - Radical hysterectomy is a **major surgical procedure** with potential complications like **hemorrhage**, infection, **ureteral injury**, and **lymphedema**, which can be significant and life-altering. - Radiotherapy, while having its own set of side effects (e.g., **vaginal stenosis**, bladder/rectal irritation), typically avoids the acute surgical risks and recovery period associated with extensive surgery. *Chance of recurrence is lower with radical hysterectomy.* - For early-stage cervical cancer (Ib1/Ib2), both **radical hysterectomy** and **radiotherapy** provide **comparable outcomes** in terms of recurrence rates. - The choice between therapies often depends on patient factors, surgeon expertise, and pathological findings, but neither consistently demonstrates a significantly lower recurrence rate over the other in large cohorts. *Ovarian function can be preserved.* - In younger patients undergoing **radical hysterectomy**, it is often possible to **preserve the ovaries** by transplanting them or avoiding their removal if not directly involved, thus maintaining **endocrine function**. - **Pelvic radiotherapy**, in contrast, invariably leads to **ovarian radiation** and subsequent **ovarian failure** and menopause. *Chance of survival is higher with radical hysterectomy.* - For early-stage cervical cancer (Ib), **overall survival rates** are generally **equivalent** between radical hysterectomy and primary radiotherapy. - Meta-analyses and large retrospective studies have shown **similar 5-year survival rates** for both treatment modalities when applied appropriately to well-selected patients.
Question 1366: Red degeneration of fibroid is seen in which of the following?
- A. Early pregnancy
- B. Mid pregnancy (Correct Answer)
- C. Nulliparous women
- D. Puerperium
Explanation: ***Mid pregnancy*** - **Red degeneration**, or **carneous degeneration**, is most common during the **second and third trimesters of pregnancy** due to increased metabolic demands of the growing fibroid outstripping its blood supply. - The rapid growth leads to **ischemia**, hemorrhage, and necrosis within the fibroid, causing acute abdominal pain. *Early pregnancy* - While fibroids can grow in early pregnancy, **red degeneration** is less common as the uterine blood supply is generally still adequate to meet the fibroid's metabolic needs. - Other forms of degeneration, like **hyaline degeneration**, are more frequently observed in non-pregnant or early pregnant states. *Puerperium* - In the puerperium, fibroids typically undergo **regression** rather than degeneration, as the hormonal stimulation (estrogen and progesterone) that promoted their growth significantly decreases. - The uterus involutes rapidly, and fibroids often shrink. *Nulliparous women* - Nulliparous women can have fibroids and experience various forms of degeneration, but **red degeneration** specifically is rare outside of pregnancy. - Degeneration in nulliparous women is more commonly **hyaline** or **cystic** degeneration.
Question 1367: Bonney's test is used to determine which of the following?
- A. Urinary incontinence due to stress (Correct Answer)
- B. Uterine prolapse
- C. Vesicovaginal fistula
- D. Ureteric fistula
Explanation: ***Urinary incontinence due to stress*** - **Bonney's test** is specifically designed to assess whether a patient's **stress urinary incontinence** is correctable by elevating the urethrovesical junction. - A positive result, where urine leakage stops with elevation, suggests that surgical correction to support the urethra may be beneficial. *Uterine prolapse* - While related to pelvic floor dysfunction, **uterine prolapse** is assessed by clinical examination for descent of the uterus, not specifically with Bonney's test. - Its presence is determined by visible or palpable protrusion of the cervix or uterus through the vaginal opening. *Vesicovaginal fistula* - A **vesicovaginal fistula** involves an abnormal connection between the bladder and vagina, leading to continuous urine leakage. - This condition is typically diagnosed using dye tests (e.g., tampon test) or cystoscopy, not Bonney's test. *Ureteric fistula* - A **ureteric fistula** is an abnormal connection involving the ureter, often resulting in continuous urine leakage outside the normal urinary tract. - Diagnosis usually involves imaging studies like IV urography or CT urogram, as Bonney's test is not relevant for this condition.
Question 1368: Which of the following is NOT a cause of metrorrhagia?
- A. Polyp
- B. CA endometrium
- C. IUD
- D. Intramural fibroid (Correct Answer)
Explanation: ***Intramural fibroid*** - **Intramural fibroids** are located within the uterine wall and are **primarily associated with menorrhagia** (heavy or prolonged menstrual bleeding during regular periods) rather than metrorrhagia. - Their main effect is to increase the endometrial surface area and impair uterine contractility, leading to **heavy regular menstrual flow**. - While they can occasionally cause irregular bleeding if complicated by degeneration or severe distortion, this is **not their typical presentation**, making them the **least characteristic cause** of metrorrhagia among the given options. *Polyp* - **Endometrial polyps** are **classic causes of metrorrhagia** because their friable surface bleeds irregularly, especially with hormonal fluctuations or minor trauma. - They commonly present with **intermenstrual spotting** and post-coital bleeding, making them a typical cause of irregular bleeding. *CA endometrium* - **Endometrial carcinoma** is a **frequent cause of metrorrhagia**, particularly in postmenopausal women, due to irregular shedding of friable malignant tissue. - The abnormal vascular supply and tissue breakdown in cancer results in **unpredictable, irregular bleeding episodes** characteristic of metrorrhagia. *IUD* - **Intrauterine devices** are **well-known causes of metrorrhagia**, particularly copper IUDs, which cause endometrial irritation and increased prostaglandin release. - Both copper and hormonal IUDs frequently cause **spotting and irregular intermenstrual bleeding**, especially in the first 3-6 months after insertion.
Question 1369: What is meant by 'Battledore insertion of placenta'?
- A. Placenta attached to the margin of the membranes
- B. Placenta attached to the center of the uterus
- C. Umbilical cord attached to the margin of the placenta (Correct Answer)
- D. Umbilical cord attached to the membranes
Explanation: ***Umbilical cord attached to the margin of the placenta*** - In a **Battledore insertion**, the **umbilical cord** inserts into the **edge** or **margin** of the placenta, rather than its center. - This unusual insertion resembles a **battledore**, a type of ancient racket or paddle with a handle at its edge (similar to those used in shuttlecock games). *Placenta attached to the margin of the membranes* - This description is more consistent with a **circumvallate placenta**, where the chorionic plate is smaller than the basal plate, leading to a rolled or folded margin of placental tissue covered by membranes, but it does not describe Battledore insertion. - In circumvallate placenta, the chorionic plate's edge rolls back and is surrounded by a ring of membranes, while Battledore refers specifically to the cord's insertion. *Placenta attached to the center of the uterus* - This simply indicates a **normal location** for the placenta within the uterine cavity and does not describe any abnormal insertion of the umbilical cord or specific characteristics of the placenta itself. - The placenta typically attaches to the uterine wall and can be central, fundal, or anterior/posterior, but this statement doesn't relate to the cord's insertion point. *Umbilical cord attached to the membranes* - This condition is known as **velamentous insertion of the umbilical cord**, where the cord blood vessels fan out within the amniotic membrane before reaching the placental tissue. - Velamentous insertion is a distinct anomaly from Battledore insertion and carries different risks, such as vasa previa and a higher risk of vessel compression or rupture.

Question 1361: What is the standard radiation dose to point A in the cervix for brachytherapy in the treatment of cervical cancer?
- A. 8000 rad (Correct Answer)
- B. 6000 rad
- C. 10000 rad
- D. 4000 rad
Explanation: ***8000 rad*** - The standard **total cumulative radiation dose** to **Point A** in the cervix for the treatment of cervical cancer is approximately **8000 rad (80 Gy)**. - This represents the **combined dose** from external beam radiation therapy (EBRT, typically 45-50 Gy) plus intracavitary brachytherapy (typically 30-40 Gy to Point A). - Point A is a classical reference point defined as **2 cm superior to the external cervical os and 2 cm lateral to the uterine canal**, representing the location where the uterine artery crosses the ureter. - This total dose aims to provide adequate tumor control while minimizing toxicity to surrounding organs like the bladder and rectum. *6000 rad* - A total dose of **6000 rad** is insufficient for definitive local control of cervical cancer. - This dose is below the therapeutic threshold and would result in significantly higher rates of local recurrence and treatment failure. - Adequate doses are essential for curative intent in cervical cancer management. *10000 rad* - A dose of **10000 rad** to Point A would be excessively high and significantly increase the risk of severe acute and late toxicities to surrounding tissues. - Such a high dose could lead to serious complications including **rectovaginal or vesicovaginal fistulas, proctitis, cystitis, bowel strictures, and tissue necrosis**. - The therapeutic window would be exceeded, causing more harm than benefit. *4000 rad* - A dose of **4000 rad** would be substantially lower than the standard therapeutic dose for cervical cancer. - This suboptimal dose would likely result in **inadequate tumor control and increased risk of local recurrence**. - It is far below the dose required for curative treatment of cervical cancer.
