Pancreatic Pathology Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Pancreatic Pathology. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Pancreatic Pathology Indian Medical PG Question 1: A 25-year-old obese woman who denies any history of alcohol abuse presents with severe abdominal pain radiating to the back. Laboratory results indicate an increase in serum amylase and lipase, with a marked decrease in calcium. Which of the following likely has caused this condition?
- A. Abetalipoproteinemia
- B. Cholelithiasis (Correct Answer)
- C. Cystic fibrosis
- D. Alcohol
Pancreatic Pathology Explanation: **Cholelithiasis**
- **Obesity** is a significant risk factor for gallstone formation [2], which can obstruct the pancreatic duct and lead to **pancreatitis** [1].
- The classic presentation of severe abdominal pain radiating to the back, elevated **amylase** and **lipase**, and **hypocalcemia** (due to fat saponification in severe pancreatitis) is highly consistent with pancreatitis secondary to gallstones [1].
*Abetalipoproteinemia*
- This is a rare genetic disorder characterized by the inability to synthesize apolipoprotein B, leading to severe **malabsorption** and **neurological deficits**, not pancreatitis.
- While it involves lipid abnormalities, it typically presents with steatorrhea, growth failure, and ataxia, not acute abdominal pain.
*Cystic fibrosis*
- Individuals with **cystic fibrosis** can develop pancreatic insufficiency and chronic pancreatitis due to thick secretions blocking pancreatic ducts, but **acute severe pancreatitis with hypocalcemia** is less typical as an initial presentation in a 25-year-old without a prior diagnosis.
- Features like **recurrent respiratory infections** and **failure to thrive** would usually precede or accompany pancreatic issues.
*Alcohol*
- Although **alcohol abuse** is a very common cause of pancreatitis, the patient explicitly **denies any history of alcohol abuse**, making this etiology less likely in this specific case.
- Clinically, alcohol-induced pancreatitis presents similarly, but the absence of positive history rules it out as the primary cause.
Pancreatic Pathology Indian Medical PG Question 2: Which of the following is included in Ranson scoring system to predict the severity of acute pancreatitis at the time of admission?
A. WBC count > 15 x 10^3/L
B. Blood glucose > 200 mg/dL
C. LDH > 350 units/L
D. AST > 250 units/L
- A. LDH > 350 units/L
- B. Blood glucose > 200 mg/dL
- C. AST > 250 units/L
- D. WBC count > 15,000/mm³ (Correct Answer)
Pancreatic Pathology Explanation: ***WBC count > 15,000/mm³***
- A **high white blood cell count** upon admission is one of the initial criteria in the Ranson scoring system indicating more severe inflammation [1].
- This parameter helps to assess the systemic inflammatory response in acute pancreatitis.
*LDH > 350 units/L*
- The Ranson criteria specify an **LDH level greater than 350 units/L** as a predictor of severity for acute pancreatitis, but it is assessed **at 48 hours after admission**, not at admission.
- This value reflects ongoing tissue damage and enzyme release.
*Blood glucose > 200 mg/dL*
- A blood glucose level > 200 mg/dL is a criterion for the Ranson score, but it is assessed **at 48 hours after admission**, not at the time of admission.
- This can indicate significant pancreatic damage impacting insulin production.
*AST > 250 units/L*
- While an elevated AST level can be present in acute pancreatitis, the specific Ranson criterion for AST is **> 250 units/L**, and it is assessed **at 48 hours after admission**, not upon admission.
- This elevation can suggest hepatobiliary involvement or severe pancreatic necrosis.
Pancreatic Pathology Indian Medical PG Question 3: Which of the following scoring systems are PRIMARILY designed for assessing the severity of acute pancreatitis?
- A. 2. APACHE score
- B. 3. MELD score
- C. 1. Ranson and Glasgow score (Correct Answer)
- D. 4. Modified Marshall score
Pancreatic Pathology Explanation: ***Ranson and Glasgow score***
- The **Ranson criteria** and the **Glasgow Coma Scale** (also known as the Imrie score) are classical scoring systems specifically developed and widely used to assess the **severity of acute pancreatitis** [1].
- Both scores incorporate multiple clinical and laboratory parameters evaluated at admission and within the first 48 hours to predict the likelihood of complications and mortality in acute pancreatitis.
*APACHE score*
- The **Acute Physiology, Age, Chronic Health Evaluation (APACHE) score** (e.g., APACHE II, APACHE III) is a general severity-of-illness classification system for critically ill patients and is not specific to acute pancreatitis.
- While it can be applied to patients with acute pancreatitis in the ICU, it's designed for a **broader range of critical illnesses** rather than primarily for pancreatitis.
*MELD score*
- The **Model for End-Stage Liver Disease (MELD) score** is used to assess the severity of **chronic liver disease** and predict prognosis, particularly for patients awaiting liver transplantation.
- It is **not designed for acute pancreatitis** and is irrelevant in this context.
*Modified Marshall score*
- The **Modified Marshall scoring system** is primarily used to assess **organ dysfunction** in acute pancreatitis, especially in clinical trials or for defining severe acute pancreatitis.
- While relevant to pancreatitis severity, it is more focused on **specific organ systems' failure** rather than providing a global predictive score for overall severity and mortality in the same way Ranson or Glasgow scores do.
Pancreatic Pathology Indian Medical PG Question 4: Consider the following findings with reference to a diagnostic peritoneal lavage (DPL) in a case of abdominal trauma :
1. 10 ml of gross blood on aspiration
2. W.B.C. count more than 500/cu mm
3. Amylase level more than 175 IU/dL
4. R.B.C. count more than 100,000/cu mm The criteria for a positive DPL are :
- A. 1 and 2 only
- B. 3 and 4 only
- C. 1, 2 and 3 only
- D. 1, 2, 3 and 4 (Correct Answer)
Pancreatic Pathology Explanation: ***1, 2, 3 and 4***
- A **positive DPL** is indicated by any of these findings: gross blood on aspiration (≥10 mL), WBC count >500/mm³, amylase level >175 IU/dL, or RBC count >100,000/mm³.
- All four criteria listed are standard indicators for a positive DPL, suggesting significant intra-abdominal injury requiring further intervention.
*1 and 2 only*
- While **gross blood aspiration** and an **elevated WBC count** are indeed criteria for a positive DPL, this option is incomplete as it omits other critical indicators.
- A **high amylase level** and **RBC count >100,000/mm³** are also definitive signs of a positive DPL.
*3 and 4 only*
- Although an **elevated amylase level** and a **high RBC count** are valid criteria, this option is insufficient because it excludes the important findings of gross blood aspiration and an elevated WBC count.
- A comprehensive assessment requires considering **all definitive indicators** for a positive DPL.
*1, 2 and 3 only*
- This option includes gross blood aspiration, elevated WBC count, and elevated amylase level, which are all positive indicators.
- However, it incorrectly excludes an **RBC count >100,000/mm³**, which is a crucial and widely accepted criterion for a positive DPL.
Pancreatic Pathology Indian Medical PG Question 5: Marker for pancreatic non-functional neuro-endocrine tumor is
- A. CEA
- B. PSA
- C. CD100
- D. Chromogranin-A (Correct Answer)
Pancreatic Pathology Explanation: ***Chromogranin-A***
- **Chromogranin-A** is a glycoprotein found in the neurosecretory granules of various neuroendocrine cells, making it a reliable **general neuroendocrine tumor marker** [1].
- Elevated levels are particularly useful for detecting and monitoring **pancreatic non-functional neuroendocrine tumors**, which often lack specific hormonal symptoms.
*CEA*
- **Carcinoembryonic antigen (CEA)** is primarily used as a tumor marker for **colorectal cancer**, and less commonly for other adenocarcinomas like pancreatic adenocarcinoma.
- It is generally **not a specific marker** for neuroendocrine tumors.
*PSA*
- **Prostate-specific antigen (PSA)** is a specific marker for **prostate cancer**, used for screening, diagnosis, and monitoring of this particular malignancy.
- It has **no relevance** in the diagnosis or monitoring of pancreatic neuroendocrine tumors.
*CD100*
- **CD100** (also known as semaphorin-4D) is a membrane glycoprotein involved in immune cell regulation and has been implicated in certain cancers, such as those of **hematopoietic origin**.
- It is **not used as a marker** for pancreatic non-functional neuroendocrine tumors.
