UPSC Medical Science 2023 — Paper II

The directive 'outline' demands a structured, systematic presentation of facts across five distinct clinical topics without elaborate discussion. Begin with a brief introduction acknowledging the breadth of topics (infectious disease, psychiatry, child health, immunization, dermatology), then address each sub-question in sequence with clear headings, bullet points for clinical features and management steps, and a concise conclusion emphasizing integrated healthcare delivery in the Indian context.

• Dengue: Distinguish DF (fever, myalgia, rash) from DHF (hemorrhagic manifestations, plasma leakage, shock) with WHO 2009 classification criteria
• Schizophrenia: Cover positive symptoms (hallucinations, delusions, disorganized speech/behavior) and negative symptoms (alogia, avolition, affective flattening) per DSM-5/ICD-10
• IMNCI: Full form (Integrated Management of Neonatal and Childhood Illnesses), objectives (reduce mortality, improve care quality), and 4 components (assess, classify, treat, counsel)
• Immunization: Complete UIP schedule including BCG, OPV, Hep-B at birth; Pentavalent, OPV, Rotavirus, IPV, PCV at 6/10/14 weeks; MR/MMR, DPT booster doses; special focus on Mission Indradhanush
• Lichen planus: Diagnosis from classic PPL (pruritic, polygonal, purple, planar papules), oral findings (Wickham striae, erosive lesions), and stepwise management (topical steroids, systemic agents for refractory cases)

The directive 'outline' demands a structured, systematic presentation of diagnostic reasoning, investigations, and management plans. Allocate approximately 40% of effort to part (a) given its 20 marks weightage, with 30% each to parts (b) and (c). Structure each case as: clinical presentation → diagnosis → investigations → management, ensuring crisp bullet points for investigations and tabular formats for CSF differentiation in (a)(iii).

• Part (a): Diagnosis of tubercular meningitis with cranial nerve involvement (CN VI palsy causing diplopia); CSF analysis showing lymphocytic pleocytosis, low glucose, high protein, and ADA levels; differentiation table of pyogenic (neutrophilic, low glucose), tubercular (lymphocytic, low glucose, high protein), and viral (lymphocytic, normal glucose) meningitis
