Q: Which of the following is not used for postcoital contraception?

Danazol. ***Danazol*** - **Danazol** is an androgen derivative primarily used to treat conditions like **endometriosis** and **fibrocystic breast disease** due to its ability to suppress gonadotropin secretion. - It is **not effective** as a postcoital contraceptive as it does not reliably prevent ovulation, fertilization, or implantation when taken after unprotected intercourse. *CuT* - The **copper-T intrauterine device (CuT IUD)** can be inserted within **5 days** of unprotected intercourse as an effective form of emergency contraception. - Its mechanism involves releasing **copper ions** that are toxic to sperm and eggs, inhibiting fertilization and implantation. *Ru 486* - **Mifepristone (RU 486)** is an **anti-progestin** that can be used for emergency contraception (often referred to as the morning-after pill). - It works by delaying or inhibiting ovulation and preventing implantation by altering the **endometrium**. *High dose estrogen* - High doses of **estrogen**, often in combination with progestin (**Yuzpe regimen**), can be used as emergency contraception. - This method primarily works by **disrupting ovulation** and altering the endometrium to prevent implantation.

Q: A 7 weeks pregnant lady has 1 accidental exposure to x-ray. Which of the following should be done?

Continue the pregnancy with monitoring. ***Continue the pregnancy with monitoring*** - The risk of **fetal malformation** and **intellectual disability** from a single diagnostic X-ray exposure is generally considered very low, often below the threshold for clinical concern. - Current guidelines typically recommend continuing pregnancy with routine monitoring unless the estimated fetal dose exceeds a certain threshold (e.g., 50-100 mGy), which is unlikely with a single accidental exposure. *Perform chromosome analysis if needed* - **Chromosome analysis** is generally reserved for cases with suspected genetic anomalies or significant fetal exposure to radiation at doses known to induce chromosomal damage. - A single, accidental X-ray exposure is unlikely to cause clinically significant chromosomal aberrations requiring such invasive testing. *Conduct pre-invasive diagnostic testing if indicated* - **Pre-invasive diagnostic testing**, such as nuchal translucency scans or maternal serum screening, assesses risks for common aneuploidies and neural tube defects, not typically direct radiation effects. - While these tests are part of routine prenatal care, a single X-ray exposure does not, by itself, create a specific indication for additional pre-invasive testing beyond standard recommendations. *Consider termination of pregnancy* - **Termination of pregnancy** is usually considered only in cases of significant, confirmed fetal harm or very high radiation doses that unequivocally increase the risk of severe birth defects or intellectual disability. - A single accidental X-ray exposure almost certainly does not meet this threshold, as the associated risks to the fetus are minimal.

Q: Given the following partogram data, identify the most likely diagnosis: Cervical dilation curve shows a prolonged labor with the cervical dilation falling to the right of the alert line.

Cephalopelvic Disproportion (CPD). ***Cephalopelvic Disproportion (CPD)*** - A cervical dilation curve that crosses the **alert line** and approaches or crosses the **action line** on a partogram indicates **prolonged labor** or **arrest of labor**. This pattern is highly suggestive of CPD, where the fetal head is too large to pass through the maternal pelvis. - While other factors can cause prolonged labor, CPD is a common cause of **protracted active phase disorders** and **labor arrest**, characterized by a cervix that fails to dilate adequately despite sufficient contractions. *Inadequate uterine contractions* - While inadequate uterine contractions (hypotonic contractions) can lead to **prolonged labor**, the partogram does not provide direct information about the frequency or intensity of contractions to conclusively make this diagnosis. - If contractions were primarily the issue, augmenting labor with oxytocin would be expected to improve the dilation curve, which is not indicated as the primary problem here. *Rupture of the uterus during labor* - Uterine rupture is a catastrophic event typically presenting with sudden **severe pain**, **vaginal bleeding**, **fetal heart rate abnormalities**, and potentially **maternal shock**. - While it can lead to cessation of labor progress, the partogram pattern of a slowly deviating dilation curve over time is not characteristic of an acute uterine rupture. *Maternal exhaustion* - Maternal exhaustion is a common consequence of **prolonged labor** but is not a primary cause of labor arrest or a specific diagnosis reflected by the cervical dilation curve alone. - It often accompanies other underlying issues like CPD or inefficient uterine contractions, rather than being the sole etiology for the observed partogram.

Q: Which of the following is not considered an absolute contraindication for the use of an Intra Uterine Contraceptive Device (IUD)?

Uterine malformation. ***Uterine malformation*** - While a uterine malformation can make IUD insertion more difficult or reduce its effectiveness, it is often considered a **relative contraindication**, depending on the specific anomaly and the patient's desire for contraception. - In certain cases, an IUD might still be a viable option, but it requires careful consideration and specialized insertion techniques. *Pregnancy* - The presence of an existing pregnancy is an **absolute contraindication** for IUD insertion, as it can lead to complications such as miscarriage or ectopic pregnancy. - An IUD is a contraceptive device, and inserting it when a woman is already pregnant directly contradicts its purpose and poses significant risks. *Undiagnosed vaginal bleeding* - This is an **absolute contraindication** because it could be a symptom of a serious underlying condition, such as cervical cancer, endometrial cancer, or ectopic pregnancy. - Inserting an IUD before diagnosing the cause of the bleeding could delay treatment of a potentially life-threatening condition and exacerbate the bleeding. *Pelvic inflammatory disease* - Current or recent (within the last 3 months) **pelvic inflammatory disease (PID)** is an **absolute contraindication** due to the increased risk of worsening infection. - IUD insertion can introduce bacteria from the vagina into the uterus, potentially exacerbating an existing infection or causing a new one.

Q: A mother brought her 16-year-old daughter to Gynaecology OPD with a complaint of not attaining menarche. She gives a history of cyclic abdominal pain. On further examination, a midline abdominal swelling is seen. Per rectal examination reveals a bulging mass in the vagina. Which of the following conditions is most likely responsible for these findings?

Imperforate hymen. ***Imperforate hymen*** - An **imperforate hymen** obstructs the outflow of menstrual blood, leading to its accumulation in the vagina (**hematocolpos**) and uterus (**hematometra**), causing **cyclic abdominal pain** and a bulging mass (due to accumulated blood) in the vagina. - The patient presents with **primary amenorrhea** (not having attained menarche) and cyclical abdominal pain caused by the inability of menstrual blood to exit the body. *Transverse vaginal septum* - A **transverse vaginal septum** can also cause primary amenorrhea and cyclic abdominal pain due to obstruction of menstrual flow. However, it is a less common cause than an imperforate hymen. - While it can lead to hematocolpos, the characteristic bulging mass on per rectal examination is more strongly associated with an imperforate hymen presenting at the vaginal introitus. *Vaginal agenesis* - **Vaginal agenesis** (complete absence of the vagina) would present with primary amenorrhea, but there would be no cyclic abdominal pain if the uterus is also absent or rudimentary. If a uterus is present, there would be no accumulation of blood in the vagina or a bulging mass per rectum as there is no vaginal canal. - This condition is typically associated with a rudimentary or absent uterus, leading to an inability to menstruate rather than obstructed flow. *Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome* - **MRKH syndrome** is characterized by congenital aplasia of the uterus and the upper two-thirds of the vagina, with normal ovaries and external genitalia. - Patients present with **primary amenorrhea** but typically do not experience **cyclic abdominal pain** or a bulging vaginal mass because there is no functional uterus to produce menstrual blood or a vaginal canal for blood accumulation.

Q: A 24-year-old woman who had a home delivery 2 weeks ago now presents with a complete perineal tear. What is the next line of management?

Repair after 3 months. ***Repair after 3 months*** - Delayed repair, typically after **3 to 6 months**, allows for resolution of **inflammation**, re-epithelialization of the wound edges, and softening of the scar tissue. - This timing optimizes conditions for successful surgical reconstruction by minimizing the risk of **infection** and promoting better tissue healing. *Repair after 3 weeks* - Repairing a complete perineal tear at this stage is too early as the tissue is still highly **inflamed** and prone to **infection** and **dehiscence**. - The wound bed would not have sufficiently healed or softened, making surgical repair more challenging and increasing the likelihood of poor outcomes. *Repair after 6 months* - Waiting for 6 months to repair a complete perineal tear is generally considered too long, as the tissues may become excessively **fibrotic** and less amenable to successful reconstruction. - While sometimes necessary in complex cases, waiting this long can lead to prolonged discomfort and functional issues for the patient. *Repair immediately* - Immediate repair of a complete perineal tear that was missed or inadequately repaired at the time of delivery is typically not recommended several weeks postpartum due to significant **edema**, **inflammation**, and potential for **infection**. - Immediate repair is usually performed **at the time of delivery** if the tear is recognized, not two weeks later.

Q: A woman with 18 weeks gestation presented to the OPD. On abdominal examination, the uterine size was 16 weeks. On USG, oligohydramnios was found, which of the following is suspected?

Renal agenesis. ***Renal agenesis*** - **Oligohydramnios** (low amniotic fluid) and a **smaller-than-expected uterine size** at 18 weeks gestation are strong indicators of fetal renal agenesis. - Fetal kidneys are crucial for producing amniotic fluid through urine excretion, so their absence or severe malfunction leads to insufficient fluid. *Jaundice* - Not directly associated with **oligohydramnios** or a smaller uterine size. - While it can occur in utero, it doesn't cause a reduction in amniotic fluid volume. *Fetal anemia* - Often associated with **hydrops fetalis** and **polyhydramnios** (excess amniotic fluid), due to increased cardiac output and fluid retention, rather than oligohydramnios. - Doesn't typically present with a uterus smaller than expected for gestational age. *Anencephaly* - A neural tube defect characterized by the absence of a major portion of the brain and skull. - It is usually associated with **polyhydramnios** (excess amniotic fluid) due to impaired fetal swallowing, making it inconsistent with the given findings.

Q: 35 yr old primigravida conceived after IVF cycle attends obstetrics clinic with 38 weeks gestation. Her obstetric details reveal DiCho-DiAmn twins with 1st twin as breech. Her BP was 140/90 mmHg on 2 occasions with proteinuria +1. How will you manage this case?

Plan a cesarean for termination. ***Plan a cesarean for termination*** - This patient presents with **preeclampsia** (BP 140/90 mmHg on two occasions with proteinuria +1) at **38 weeks gestation**, making delivery appropriate. - The presence of **DiCho-DiAmn twins** with the **first twin in breech presentation** is a strong indication for **cesarean section** to ensure safe delivery and reduce complications. *Induction of labour* - While induction might be considered for preeclampsia, the **breech presentation of the first twin** in a twin pregnancy significantly increases the risks associated with vaginal delivery, making it less safe than a cesarean. - Given the combined risk factors, **cesarean delivery** is the more appropriate choice for optimizing maternal and fetal outcomes. *Watch for BP and induce for normal delivery on Expected Date of delivery* - Preeclampsia necessitates **delivery when the mother reaches 37 weeks or beyond**, not necessarily waiting until the Expected Date of Delivery, especially with other complicating factors. - Furthermore, attempting a **normal vaginal delivery** with a **breech presenting twin 1** carries high risks for both twins and is generally contraindicated. *Watch for BP and terminate (vaginal/ Cesarean) only when BP is normal.* - Delaying termination until blood pressure normalizes is not appropriate management for **preeclampsia** at term; delivery is the definitive treatment. - A persistent **breech presentation of twin 1** also makes vaginal delivery problematic, regardless of blood pressure status.

Q: 35 yr old lady attends gynaec OPD with excessive bleeding since 6 months, not controlled with non hormonal drugs. USG and clinical examination reveals no abnormality. Next step is?

Endometrial sampling. ***Endometrial sampling*** - In a 35-year-old with **excessive uterine bleeding** not controlled by non-hormonal drugs and with normal imaging/clinical exam, endometrial sampling is crucial to **rule out endometrial hyperplasia or malignancy**. - This diagnostic step is essential before considering definitive treatments, as it provides a **histological diagnosis** of the endometrial lining. *Hysterectomy* - Hysterectomy is a **definitive surgical treatment** for excessive bleeding, but it is typically reserved for cases where conservative or less invasive treatments have failed, or if there's a serious underlying pathology like malignancy. - It involves removing the uterus and is a **major surgery** with potential complications, thus not usually the first step given an otherwise normal examination and imaging. *Endometrial ablation* - Endometrial ablation is a procedure to destroy the lining of the uterus, aiming to **reduce or stop menstrual bleeding**. - It is a treatment option for **abnormal uterine bleeding (AUB)**, but it's typically performed after other diagnostic steps (like endometrial sampling) have ruled out malignancy or high-risk hyperplasia, and when conservative medical management has failed. *Hormonal therapy* - Hormonal therapy (e.g., combined oral contraceptives, progestin-only pills, levonorgestrel-releasing intrauterine device) is often a **first-line medical treatment** for excessive uterine bleeding. - However, the question states that non-hormonal drugs have already failed, and without a clear diagnosis, initiating new hormonal therapy without **evaluating the endometrium** is not the next best step for persistent bleeding.

Q: A female undergoing treatment for infertility with IVF was given Inj. HCG, presented with a history of vomiting, nausea, and headache. The USG is shown as below, what is the diagnosis?

Ovarian Hyperstimulation Syndrome. ***Ovarian Hyperstimulation Syndrome*** - The patient's history of **IVF treatment** with **HCG administration**, combined with symptoms like **nausea**, **vomiting**, and **headache**, strongly suggests **Ovarian Hyperstimulation Syndrome (OHSS)**. - The USG image would likely show enlarged, multicystic ovaries, which is characteristic of OHSS due to an exaggerated response to ovarian stimulation. *Theca lutein Cysts* - While **theca lutein cysts** can be associated with high HCG levels (e.g., in molar pregnancy or multiple gestations), they are usually benign and often asymptomatic, or present with milder symptoms than described. - Unlike OHSS, theca lutein cysts typically do not involve the systemic symptoms of fluid shifts and inflammation seen in this case. *Granulosa cell Tumor* - A **granulosa cell tumor** is a type of ovarian cancer, and while it may present with symptoms related to hormone production (e.g., estrogen), it is not directly caused by IVF treatment or HCG administration. - The clinical presentation of sudden onset symptoms following IVF is not typical for an ovarian neoplasm. *PCOS* - **Polycystic Ovary Syndrome (PCOS)** is a common cause of infertility, but it is a chronic condition characterized by hormonal imbalances, anovulation, and polycystic ovaries. - While patients with PCOS may undergo IVF, the acute symptoms of vomiting, nausea, and headache following HCG administration are not direct manifestations of PCOS itself, but rather a complication of the treatment for infertility.
