NEET-PG 2013 Practice Questions

Q: A patient presents with bilateral ovarian carcinoma, capsule involvement, ascites, and paraaortic lymphadenopathy. What is the appropriate stage of the disease?

Stage 3C. ***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.

Q: Which of the following statements about radical hysterectomy in stage Ib cervical cancer compared to radiotherapy is false?

It is less complicated than radiotherapy.. ***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.

Q: Red degeneration of fibroid is seen in which of the following?

Mid pregnancy. ***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.

Q: Bonney's test is used to determine which of the following?

Urinary incontinence due to stress. ***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.

Q: Which of the following is NOT a cause of metrorrhagia?

Intramural fibroid. ***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.

Q: What is meant by 'Battledore insertion of placenta'?

Umbilical cord attached to the margin of the placenta. ***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.

Q: Hematuria in previous LSCS patient indicates -

Urinary tract infection. ***Urinary tract infection*** - Hematuria in a patient with a previous **LSCS** (Lower Segment Caesarean Section) is a common symptom of a **urinary tract infection (UTI)**, as pregnancy itself, and sometimes a previous C-section, can increase UTI risk. - While a previous LSCS might alter pelvic anatomy, a UTI is a more direct and common cause of hematuria in this scenario than other obstetrical complications. *Placenta previa* - **Placenta previa** primarily causes **painless vaginal bleeding** in the second or third trimester due to the placenta covering the cervical os, not hematuria directly from the urinary tract. - While bleeding might be significant, it originates from the uterus, not the bladder, and is typically bright red vaginal bleeding. *No significant findings* - **Hematuria** is a significant finding that warrants investigation, as it indicates blood in the urine and is never considered "no significant finding." - It could be a sign of various underlying conditions, ranging from benign to serious, necessitating evaluation. *Rupture uterus* - **Uterine rupture** is a catastrophic event in pregnancy, often presenting with **severe abdominal pain**, fetal distress, and significant **vaginal bleeding**, not isolated hematuria. - While it's a serious complication, the blood would primarily be from the uterus or internal hemorrhage, not directly in the urine.

Q: What is the standard radiation dose to point A in the cervix for brachytherapy in the treatment of cervical cancer?

8000 rad. ***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.

Q: Investigation with least radiation dose in the diagnosis of Meckel's diverticulum is -

Technetium -99m scanning. ***Technetium-99m scanning*** - **Technetium-99m pertechnetate scan** (Meckel's scan) is the **gold standard investigation** for diagnosing Meckel's diverticulum with ectopic gastric mucosa - Among the investigations that can actually **diagnose Meckel's diverticulum**, it has the **lowest radiation dose** (approximately 1-2 mSv) - The radioisotope is specifically taken up by ectopic gastric mucosa, providing both diagnostic utility and relatively low radiation exposure - **Sensitivity: 85-95%** for detecting ectopic gastric mucosa in Meckel's diverticulum - The radiation dose is comparable to a few months of natural background radiation and significantly lower than CT or contrast studies *MRI* - While **MRI uses no ionizing radiation**, it is **not a standard or practical investigation** for diagnosing Meckel's diverticulum - MRI cannot identify ectopic gastric mucosa specifically - It is rarely used in clinical practice for this indication - The question asks about investigation "in the diagnosis" of Meckel's diverticulum, implying a test that is actually used diagnostically *CT* - **Computed Tomography (CT)** delivers a **high radiation dose** (typically 5-10 mSv or more) - While it can identify structural abnormalities, it is not specific for Meckel's diverticulum - Not the first-line investigation for this condition *Contrast radiography* - **Contrast studies** (barium studies) use **moderate ionizing radiation** (3-5 mSv) - Limited utility in diagnosing Meckel's diverticulum as it primarily assesses luminal patency - Cannot identify ectopic gastric mucosa - Lower sensitivity compared to Tc-99m scanning
