Question 961: Caput succedaneum indicates that the fetus was alive until which point?
- A. Immediately after birth (Correct Answer)
- B. Till 2-3 days after birth
- C. 2-3 weeks after birth
- D. 2-3 months after birth
Explanation: ***Immediately after birth*** - **Caput succedaneum** is a benign condition characterized by a **diffuse, edematous swelling** of the fetal scalp, crossing suture lines. - It results from pressure on the fetal head during vertex delivery, causing **extravasation of fluid** into the subcutaneous tissue, indicating the fetus was alive and circulating blood until birth. *Till 2-3 days after birth* - This option is incorrect because **caput succedaneum** is a direct consequence of the **birthing process** itself, forming during labor and delivery. - The presence of this scalp swelling signifies that the baby was alive and experienced the forces of birth, not that it survived for several days afterward. *2-3 weeks after birth* - This option is incorrect as **caput succedaneum** typically resolves within a few days of birth. - Its presence is a temporary finding related to the immediate perinatal period and does not indicate survival for several weeks. *2-3 months after birth* - This option is incorrect because **caput succedaneum** is a transient condition appearing at birth and usually disappearing within a few days. - It has no implication for the baby's survival beyond the immediate postnatal period, let alone for several months.
Question 962: What is the treatment of choice for Bartholin's cyst?
- A. Excision
- B. Antibiotic therapy
- C. Marsupialization (Correct Answer)
- D. Cyst drainage
Explanation: ***Marsupialization*** - This procedure involves incising the cyst, draining its contents, and then everting and suturing the edges of the cyst wall to the surrounding skin, creating a permanent-draining pouch. - **Marsupialization** is the treatment of choice because it prevents recurrence by allowing continuous drainage of mucus, unlike simple incision and drainage. *Excision* - Complete surgical excision of the Bartholin's gland or cyst is a more invasive procedure and is typically reserved for cases of **recurrent cysts** after marsupialization or suspected malignancy. - It carries a higher risk of bleeding and infection compared to marsupialization, and can lead to **vaginal dryness** due to loss of glandular secretions. *Antibiotic therapy* - Antibiotics are primarily used if the Bartholin's gland becomes **infected**, leading to an **abscess**, or if there is surrounding cellulitis. - They do not address the underlying blockage of the duct and will not resolve a Bartholin's cyst, which is a collection of mucus due to duct obstruction. *Cyst drainage* - Simple incision and drainage (I&D) provides temporary relief by emptying the cyst contents but has a **high recurrence rate** because the duct often re-occludes. - While it may be used as an initial temporizing measure, it is not the definitive treatment for preventing future episodes of Bartholin's cysts.
Question 963: Gold standard technique for diagnosis of endometriosis?
- A. Ca 125 level
- B. Ultrasound
- C. MRI
- D. Laparoscopy (Correct Answer)
Explanation: ***Laparoscopy*** - **Laparoscopy** allows for direct visualization of endometrial implants and enables **biopsy confirmation**, making it the gold standard. - This minimally invasive surgical procedure is crucial for diagnosing, staging, and often treating endometriosis simultaneously. *Ca 125 level* - **CA-125** is a serum marker that can be elevated in endometriosis, but it is **not specific** and can be raised in other conditions like ovarian cancer or physiologic states. - It is primarily used for monitoring treatment response or recurrence, rather than as a primary diagnostic tool. *Ultrasound* - **Transvaginal ultrasound (TVS)** can identify endometriomas (chocolate cysts) and deep infiltrating endometriosis, but it cannot reliably visualize small peritoneal implants. - While it's a good initial imaging modality, its sensitivity for diagnosing all forms of endometriosis is **limited**. *MRI* - **MRI** offers better soft tissue contrast than ultrasound and can identify deep infiltrating endometriosis and some peritoneal implants, especially those involving the bowel or bladder. - However, MRI is **more expensive** and less accessible, and it still cannot definitively rule out all small, superficial endometrial lesions without direct visualization.
Question 964: Which of the following statements about Asherman's syndrome is true?
- A. May be secondary to TB
- B. Progesterone challenge test is positive
- C. Characterized by intrauterine adhesions (Correct Answer)
- D. Not associated with menstrual irregularities
Explanation: ***Characterized by intrauterine adhesions*** - **Asherman's syndrome** is fundamentally defined by the presence of **intrauterine adhesions** or scarring of the uterine cavity. - These adhesions develop following trauma to the basal layer of the endometrium, often from gynecological procedures like **dilation and curettage (D&C)**. - This is the **pathognomonic feature** that defines the syndrome. *Progesterone challenge test is positive* - The **progesterone challenge test** assesses the presence of an intact endometrium and adequate estrogen priming. - In Asherman's syndrome, due to the scarred endometrium, the response to progesterone is typically **absent or minimal**, leading to a **negative** result. - A negative progesterone challenge test indicates outflow obstruction or endometrial non-responsiveness. *May be secondary to TB* - While **genital tuberculosis** can cause intrauterine adhesions and is a recognized etiology, it represents a **small minority** of cases. - The primary etiology of Asherman's syndrome is usually **iatrogenic**, following uterine instrumentation such as D&C, particularly post-partum or post-abortion. - TB-related adhesions may have additional features like caseating granulomas. *Not associated with menstrual irregularities* - This is **false** - Asherman's syndrome is classically associated with **menstrual irregularities**. - Common presentations include **hypomenorrhea** (scanty periods), **amenorrhea** (absent periods), or oligomenorrhea. - These menstrual changes result from the reduced functional endometrium available for cyclical shedding due to intrauterine adhesions.
Question 965: What is the investigation of choice in postmenopausal bleeding?
- A. PAP smear
- B. Laparoscopy
- C. Fractional curettage
- D. Ultrasound (Correct Answer)
Explanation: ***Ultrasound*** - An initial **transvaginal ultrasound** is the investigation of choice to assess the endometrial thickness in postmenopausal bleeding. An endometrial thickness of >4-5mm often warrants further investigation. - It helps in **ruling out endometrial pathologies** like hyperplasia, polyps, or carcinoma. *PAP smear* - A **PAP smear** is a screening test for cervical cancer, not typically used to investigate postmenopausal bleeding originating from the uterus. - While it can detect some endometrial cells, it is **not sensitive** or specific enough to diagnose the cause of postmenopausal bleeding. *Laparoscopy* - **Laparoscopy** is a surgical procedure used to visualize pelvic organs and is generally employed for diagnosing and treating conditions like endometriosis, ovarian cysts, or ectopic pregnancies. - It is **not the initial investigation** for postmenopausal bleeding and is too invasive for primary diagnosis unless other methods have failed or a specific pathology is suspected. *Fractional curettage* - **Fractional curettage** involves scraping the lining of the cervix and uterus to obtain tissue samples for histological examination. - While it can be diagnostic for endometrial pathology, it is typically performed **after an initial ultrasound** has identified increased endometrial thickness or other suspicious findings, and less commonly as a standalone initial investigation.
Question 966: Which IUD is preferred for menorrhagia?
- A. NOVA T
- B. Cu IUD
- C. Mirena (Correct Answer)
- D. Gynefix
Explanation: ***Mirena*** - The **Mirena** IUD contains **levonorgestrel**, a progestin, which significantly reduces menstrual blood loss by causing endometrial atrophy. - It is FDA-approved for the treatment of **menorrhagia** and is highly effective in reducing heavy menstrual bleeding. *NOVA T* - **NOVA T** is a **copper IUD**, which can actually *increase* menstrual blood loss and dysmenorrhea, making it unsuitable for menorrhagia. - Copper IUDs work primarily by inducing a **local inflammatory reaction** in the uterus that is spermicidal and prevents fertilization. *Cu IUD* - Like NOVA T, **copper IUDs (Cu IUDs)** are known to exacerbate **heavy menstrual bleeding** and cramping. - They are used for contraception but are generally contraindicated in women with pre-existing menorrhagia. *Gynefix* - **Gynefix** is a frameless copper IUD designed to reduce the side effects of traditional T-shaped copper IUDs. - While it may cause less cramping than other copper IUDs, it still contains copper and can **increase menstrual flow**, making it a poor choice for menorrhagia.
Question 967: What is the typical pH of the vagina in a pregnant woman?
- A. 4.0 (Correct Answer)
- B. 4.5
- C. 5
- D. >5
Explanation: ***4.0*** - The typical vaginal pH in a pregnant woman is **acidic**, generally ranging from 3.5 to 4.5, with **4.0 being the most commonly cited average value** during pregnancy. - This **acidic environment** is crucial for maintaining a healthy vaginal flora, primarily dominated by **Lactobacillus species**, which produce lactic acid from glycogen deposits in vaginal epithelium. - The increased estrogen levels during pregnancy promote glycogen deposition, supporting lactobacilli growth and maintaining this acidic pH. *4.5* - While 4.5 is **also within the normal range** (3.5-4.5) for pregnant women, it represents the **upper limit** of normal vaginal pH during pregnancy. - Although still physiologic, **4.0 is more commonly referenced** as the typical value in obstetric literature, making it the best answer for "typical" pH. - A pH consistently at 4.5 or trending upward may warrant monitoring, though it is not necessarily pathological. *5* - A pH of 5 is considered **elevated** and is typically associated with conditions like **bacterial vaginosis** (BV) or **trichomoniasis**, which increase the risk of preterm labor and other complications. - A pH of 5 in pregnancy would raise suspicion and warrant further investigation, as it indicates a **less acidic** environment and disruption of normal lactobacilli-dominated flora. - This elevated pH suggests loss of the protective acidic environment. *>5* - A pH greater than 5 is **abnormal** for a pregnant woman and strongly suggests the presence of a **vaginal infection**, such as bacterial vaginosis, trichomoniasis, or aerobic vaginitis. - This **alkaline shift** favors the growth of pathogenic bacteria over beneficial lactobacilli, significantly increasing the risk of adverse pregnancy outcomes including preterm birth and chorioamnionitis. - Requires prompt evaluation and treatment.
Question 968: Vaginal pH before puberty is?
- A. Approximately 6
- B. Approximately 4.5
- C. Approximately 5
- D. Neutral (around 7) (Correct Answer)
Explanation: ***Neutral (around 7)*** - Before puberty, the vagina lacks the influence of **estrogen**, which is essential for the colonization of **Lactobacillus** bacteria. - Without Lactobacillus, there is no significant production of lactic acid, resulting in a **neutral pH** environment. *Approximately 6* - A pH of approximately 6 is still slightly acidic but less so than a mature vagina. - This value is not typical for the prepubertal stage, which generally represents an environment without significant acidic production. *Approximately 4.5* - A pH of approximately 4.5 is characteristic of a **healthy, estrogenized adult vagina** where **Lactobacillus** bacteria produce lactic acid. - This acidic environment is crucial for protecting against pathogenic infections and is not found in prepubertal individuals. *Approximately 5* - A pH of approximately 5 is acidic, though less so than the optimal adult vaginal pH. - This value indicates some lactic acid production, which is minimal or absent before the onset of puberty.
Orthopaedics
1 questionsWhat is the primary reason for early stabilization of a femur shaft fracture?
NEET-PG 2012 - Orthopaedics NEET-PG Practice Questions and MCQs
Question 961: What is the primary reason for early stabilization of a femur shaft fracture?
- A. To prevent significant blood loss.
- B. To reduce pain and discomfort.
- C. To facilitate quicker healing.
- D. To prevent fat embolism syndrome and systemic complications (Correct Answer)
Explanation: ***To prevent fat embolism syndrome and systemic complications*** - Early stabilization of femur shaft fractures significantly **reduces the incidence of fat embolism syndrome (FES)**. Fat emboli released from the bone marrow can travel to the lungs and brain, causing severe respiratory distress and neurological deficits. - By stabilizing the fracture, the **release of fat globules is minimized**, thereby preventing FES and associated systemic complications such as acute respiratory distress syndrome (ARDS) and adult respiratory distress syndrome (ADRS). *To prevent significant blood loss.* - While femur fractures can cause significant blood loss, the primary reason for early stabilization is not solely to prevent it but to reduce complications. **Blood loss is a direct consequence**, but FES poses a greater immediate threat to life. - Furthermore, **blood loss can often be managed initially by other means**, such as fluid resuscitation and direct pressure, while FES requires prompt reduction of fracture movement. *To reduce pain and discomfort.* - Reducing pain and discomfort is an important benefit of stabilization, but it is **not the primary life-saving reason** for early intervention. Analgesics and proper splinting can also address pain. - The focus on early stabilization goes beyond symptomatic relief to actively prevent **potentially fatal systemic complications**. *To facilitate quicker healing.* - While stability is crucial for proper healing, **early stabilization primarily addresses acute, life-threatening complications** rather than long-term healing rates. Optimal healing depends on many factors, including blood supply and infection control, not solely on initial stabilization. - **Quicker healing is a secondary benefit**; the immediate priority is to prevent acute morbidity and mortality associated with the fracture.
Pathology
1 questionsIn which condition is pannus formation typically observed?
NEET-PG 2012 - Pathology NEET-PG Practice Questions and MCQs
Question 961: In which condition is pannus formation typically observed?
- A. RA (Correct Answer)
- B. Osteoarthritis (OA)
- C. Gout (Gouty Arthritis)
- D. Psoriatic Arthritis (PsA)
Explanation: ***RA*** - **Pannus** is a characteristic feature of **rheumatoid arthritis**, representing an aggressive, hyperplastic synovial tissue that invades and destroys cartilage and bone [1], [2]. - This destructive granulation tissue primarily consists of fibroblasts, macrophages, and inflammatory cells, contributing to joint erosion [1]. *Osteoarthritis (OA)* - While **osteophytes** (bone spurs) and **cartilage degradation** are hallmarks of OA, **pannus formation** is not seen. - OA involves breakdown of articular cartilage due to mechanical stress and biochemical changes, not synovial invasion. *Gout (Gouty Arthritis)* - Gout is characterized by the deposition of **monosodium urate crystals** in joints, leading to acute inflammation [4]. - The formation of **tophi** (urate crystal deposits) is typical, but not **pannus** [4]. *Psoriatic Arthritis (PsA)* - PsA can cause joint inflammation and erosion similar to RA but does not typically involve the extensive **pannus formation** characteristic of RA [3]. - Specific features of PsA include **enthesitis**, dactylitis and involvement of **DIP joints** [3]. **References:** [1] Cross SS.
