Question

(a) Define 'pre-eclampsia'. Enumerate the risk factors which may lead to this condition. What are its clinical signs and what are its alarming symptoms ? Outline in brief its management. 3+5+6+6=20

(b) Describe clinical features, diagnosis and management of ileo-caecal tuberculosis. 5+5+5=15

(c) (i) What are the objectives of investigating an epidemic ?
(ii) Briefly state the various steps you would undertake while investigating an epidemic. 5+10=15

UPSC Answer Check · Accepted Answer

The directive 'describe' demands comprehensive, structured coverage of clinical entities and processes across all four sub-parts. Allocate approximately 40% of time/words to part (a) given its 20 marks, 30% to part (b) for 15 marks, and 30% combined to (c)(i) and (c)(ii) for 15 marks. Structure as: (a) definition → risk factors → clinical signs → alarming symptoms → management; (b) clinical features → diagnosis → management; (c) objectives → systematic investigation steps. Use Indian epidemiological data (e.g., NFHS-5 for maternal health, RNTCP for TB, IDSP for outbreak investigation) throughout.
- Part (a): Precise definition of pre-eclampsia (new-onset hypertension + proteinuria after 20 weeks); risk factors include nulliparity, chronic hypertension, multiple gestation, renal disease; clinical signs (BP ≥140/90, proteinuria, edema); alarming symptoms (headache, visual disturbances, epigastric pain, hyperreflexia); management per FIGO/WHO guidelines with antihypertensives, magnesium sulfate, delivery timing
- Part (b): Ileo-caecal TB features (abdominal pain, mass, obstruction, alternating constipation-diarrhea); diagnosis via colonoscopy with biopsy (caseating granulomas), CT/MRI showing 'comb sign', ascitic fluid ADA, GeneXpert MTB/RIF; ATT regimen per RNTCP (2HRZE/4HRE) with surgery for complications
- Part (c)(i): Epidemic investigation objectives: verify diagnosis, determine extent, identify source/mode of transmission, implement control, formulate hypotheses, train personnel
- Part (c)(ii): Systematic steps: prepare for field work, establish existence of epidemic, verify diagnosis, define and count cases, orient data by person/place/time, formulate/test hypotheses, implement control measures, communicate findings (reference IDSP outbreak response protocol)
- Integration: Application of Indian public health frameworks (RNTCP, IDSP, MCP) and recent epidemiological data (e.g., rising TB-DM comorbidity, maternal mortality trends)

Dimension	Weight	Max marks	Excellent	Average	Poor
Concept correctness	20%	10	For (a): Accurate ISHHP/ACOG definition distinguishing pre-eclampsia from gestational hypertension; for (b): Correct pathophysiology of ileo-caecal TB as intestinal form with ulcerative/hypertrophic types; for (c): Precise epidemiological terminology (attack rate, case fatality, epidemic threshold) per IDSP manual	Basic definitions correct but misses nuanced distinctions (e.g., pre-eclampsia vs eclampsia timing, primary vs secondary intestinal TB); some epidemiological terms used imprecisely	Fundamental errors in definition (e.g., pre-eclampsia before 20 weeks), confuses ileo-caecal TB with Crohn's pathophysiology, or misstates epidemic investigation purpose
Clinical correlation	20%	10	For (a): Links HELLP syndrome, eclampsia progression; for (b): Correlates ileo-caecal TB presentation with malabsorption, fistula formation; for (c): Connects investigation steps to real Indian outbreaks (e.g., Nipah in Kerala, AES in Bihar) with demographic risk profiling	Mentions complications superficially without mechanistic explanation; generic outbreak examples without Indian context; limited integration of clinical findings	No clinical correlation shown; lists facts without disease progression understanding; fails to mention any Indian epidemiological context
Diagram / pathway	15%	7.5	Includes labeled diagram of placental vasculature in pre-eclampsia (shallow trophoblast invasion) OR epidemic curve (histogram) for part (c); flowchart for management algorithm; clear visual representation of investigation steps	Mentions need for diagrams but execution poor or absent; rough sketch without labels; text description substitutes for visual	No diagrams despite clear visual potential; completely text-based answer where figures would significantly aid explanation
Differential / staging	20%	10	For (a): Distinguishes pre-eclampsia from chronic hypertension, gestational hypertension, renal disease; severity staging (mild vs severe); for (b): Differentiates from Crohn's disease, lymphoma, carcinoma, ameboma; for (c): Classifies outbreak types (common source vs propagated vs mixed)	Lists differentials without distinguishing features; mentions severity but no clear criteria; basic outbreak classification without application	No differential diagnosis attempted; confuses conditions entirely; misses critical distinctions affecting management
Management / public-health angle	25%	12.5	For (a): Evidence-based management (labetalol, nifedipine, magnesium sulfate prophylaxis, delivery timing per severity); for (b): RNTCP Category I/III regimen, surgery indications (obstruction, perforation); for (c): IDSP protocol implementation, notification, vaccination response, health education—demonstrates field applicability	Generic management without specific drug dosages or guidelines; mentions ATT without regimen details; basic outbreak control without systematic approach	Outdated or dangerous management suggestions; no public health perspective; ignores national program frameworks (RNTCP, IDSP, MCP)
