Q: Which of the following is the correct definition of postpartum pyrexia?

After 24 hours, temperature > 100.4 degrees Fahrenheit. ***After 24 hours, temperature > 100.4 degrees Fahrenheit***- The standard definition of **postpartum pyrexia** (puerperal fever) requires a temperature of **100.4°F (38.0°C)** or higher, recorded on any two of the first 10 postpartum days.- Importantly, this definition **excludes the first 24 hours** post-delivery, as transient fever during this period is common and often non-infectious (**dehydration** or **trauma**).*After 6 hours, temperature > 100.4 degrees Fahrenheit*- This time threshold is too early; transient, often benign, fever spikes are common in the immediate six hours following delivery due to physiological changes or **epidural use**.- Using this timeframe would lead to over-diagnosis of **puerperal morbidity** or infection.*After 3 hours, temperature > 100.4 degrees Fahrenheit*- Fever occurring this early is usually reflective of labor-related issues like **chorioamnionitis** present before delivery or non-infectious causes related to the immediate **postpartum stress**.- The standard definition purposefully excludes the initial period to distinguish between immediate physiological responses and actual **puerperal infection**.*After 12 hours, temperature > 100.4 degrees Fahrenheit*- While closer to the standard definition, 12 hours is still too soon, as the standard clinical parameter for defining significant infection requires symptoms to persist starting **after the first 24 hours**.- This window still often includes temporary fevers that resolve spontaneously and are not indicative of true **postpartum infection**.

Q: A 32-year-old woman presents with intermenstrual bleeding following the insertion of an intrauterine device (IUD). She reports no other complications. What is the most appropriate initial management step?

Reassure the patient and observe. **Reassure the patient and observe (Correct)** - Irregular bleeding (spotting or intermenstrual bleeding) is a very common and expected side effect, especially during the first **3 to 6 months** after IUD insertion (both copper and hormonal). - In the absence of signs of infection (fever, purulent discharge, pelvic pain), IUD expulsion, or pregnancy, the initial management is typically **reassurance** that symptoms often resolve spontaneously. *Remove the IUD (Incorrect)* - IUD removal is generally reserved for failure of medical management, **IUD expulsion**, severe complications (e.g., **perforation**), or persistent, unacceptable side effects after the initial adaptation period. - Removing the IUD prematurely for expected spotting unnecessarily terminates a highly effective form of **contraception**. *Perform a pelvic ultrasound (Incorrect)* - Imaging is usually indicated if there is suspicion of **IUD malposition** (e.g., missing strings, pain, suspected expulsion) or to rule out other causes of bleeding like **pregnancy** or structural uterine abnormalities (fibroids, polyps). - Since the bleeding is expected and transient in the immediate post-insertion phase, an ultrasound is generally not mandatory as the *initial* step in an otherwise asymptomatic patient. *Prescribe hormonal therapy (Incorrect)* - While treatments like low-dose **estrogen** or **NSAIDs** can sometimes manage persistent, heavy bleeding, simple spotting is typically managed conservatively first. - Adding hormonal therapy might mask important underlying issues or add unnecessary risk/side effects for a symptom that is likely to resolve spontaneously.

Q: A 27-year-old pregnant female in her first trimester presents to the OPD for a regular antenatal checkup. During blood type screening, potential ABO incompatibility is discussed. The healthcare provider explains that certain antibody types are less concerning than others during pregnancy. ABO incompatibility does not occur due to which antibody in her case?

IgM. ***IgM***- The predominant natural antibodies against **ABO antigens** (anti-A and anti-B) are of the **IgM class**, which are large pentameric molecules. These **IgM antibodies** generally cannot cross the placenta due to their size, meaning they do not reach the fetal circulation and cause significant hemolytic disease of the newborn (HDN). *IgA*- IgA is predominantly found in secretions (mucous membranes, breast milk) and is not generally involved in causing **hemolytic disease of the newborn (HDN)**, as it does not cross the placenta in significant amounts. This antibody class is not the primary mechanism of incompatibility, as the most common non-transmissible antibodies are IgM. *IgG*- **IgG is the only class** of immunoglobulin that efficiently crosses the placenta into the fetal circulation, meaning that any present **IgG anti-A or anti-B antibodies** are the ones responsible for causing **fetal red cell hemolysis** in ABO incompatibility. Though ABO HDN is usually less severe than Rh HDN, the pathology depends entirely on the presence of IgG. *IgD*- IgD antibodies are primarily expressed on the surface of naïve **B lymphocytes** and are involved in B cell activation and signaling. They are not involved in **red blood cell agglutination** or placental transfer relevant to ABO incompatibility. [Practice more Obstetrics and Gynecology PYQs on OnCourse]

Q: Identify the option with the least risk of TOLAC (trial of labor after cesarean)?

Low-segment transverse incision. ***Low-segment transverse incision*** - This type of uterine incision is preferred during a Cesarean section as it is made in the least active segment, carrying the **lowest risk** of **uterine rupture** (approximately 0.5% to 0.9%) during a subsequent trial of labor. - It is generally considered the standard requirement for safely proceeding with a **VBAC** (Vaginal Birth After Cesarean) attempt. *Classical C section* - A **classical C-section** involves a vertical incision in the contractile upper segment (**uterine fundus**), which has the highest risk of **uterine rupture** (4% to 9%) during labor. - A history of a classical incision is generally considered an absolute **contraindication** to TOLAC. *Pre-eclampsia* - The presence of **pre-eclampsia** increases the risk of adverse outcomes to both mother and fetus, such as **placental abruption** and **intrauterine growth restriction**. - While not an absolute contraindication, it complicates management and often necessitates induction or delivery, placing it at a higher risk level compared to an uncomplicated TOLAC attempt. *Breech presentation* - **Breech presentation** is itself a risk factor for difficult vaginal delivery in nulliparous women, and combining it with a prior Cesarean scar (TOLAC) elevates the overall obstetric risk. - Many practitioners consider **breech presentation** in the current pregnancy a relative contraindication to TOLAC, favoring a planned repeat Cesarean delivery due to increased risk of complications.

Q: Identify the gynecological instrument shown in the image below:

Cusco vaginal speculum. ***Cusco vaginal speculum*** - In the given image, the instrument shows the characteristic **bivalve design** with two curved blades that can be opened and closed using a **screw mechanism** visible at the handle, which is the defining feature of a Cusco speculum. - The **self-retaining mechanism** and **smooth, curved blades** designed for routine gynecological examinations like **Pap smears** are clearly visible, distinguishing it from other speculums. *Graves vaginal speculum* - The Graves speculum has **wider, more angled blades** that contour to the vaginal fornices, which is not seen in the image. - It typically has a **different handle configuration** and blade curvature compared to what's shown in the instrument. *Auvard speculum* - This is a **weighted speculum** with a distinctly different design featuring a **heavy posterior blade** for retraction during procedures like **D&C**. - The instrument in the image lacks the characteristic **weighted design** and **single posterior blade** typical of an Auvard speculum. *Sims speculum* - The Sims speculum is **non-self-retaining** and has a **double-ended, curved design** that requires manual holding or assistance. - Unlike the instrument shown, it lacks a **screw mechanism** and has a completely different **curved, hook-like shape**.
