Model answer
Written by UPSC Answer Check against this question's marking rubric, to the expected length. UPSC does not publish answers for Mains — this is one way to score well, not an official key.
EPTB diagnosis. Diagnosis is multimodal because no single test is uniformly confirmatory. Under NTEP, CBNAAT/GeneXpert MTB/RIF is performed on tissue, pleural fluid, CSF, lymph-node aspirate or urine where available, giving rapid detection and rifampicin resistance; CBNAAT is preferred for paucibacillary EPTB, while culture remains reference but slow. Line probe assay is used on smear-positive specimens or culture isolates, not directly on most tissue biopsies, to detect rifampicin and fluoroquinolone resistance. Histopathology showing caseating granulomas supports TB; AFB smear/culture may support the diagnosis but has low sensitivity and is not a confirmatory standard for most EPTB. ADA levels in pleural or CSF fluid aid diagnosis. Imaging is essential: MRI for Pott’s spine and spinal cord compression, CT for abdominal, lymph-node and genitourinary TB; FNAC/cytology is used for lymph-node and soft-tissue disease.
Malabsorption syndrome. It is described by chronic fat-soluble and nutrient malabsorption: steatorrhea, weight loss, anaemia from iron, B12 or folate deficiency, and oedema from hypoproteinaemia. Bloating, flatulence, fatigue, and neuropathy or osteomalacia may accompany the core features. Celiac disease may show dermatitis herpetiformis, anti-tTG positivity and duodenal villous atrophy; tropical sprue occurs after tropical exposure with folate/B12 deficiency and responds to antibiotics; Whipple’s disease gives PAS-positive macrophages, arthralgia and chronic diarrhoea.
BFHI 2018 Ten Steps. The revised framework is: 1. Have a written breastfeeding policy, compliant with the International Code, to routine staff, mothers, and families; 1a. The policy is communicated to all healthcare staff; 1b. The policy is communicated to mothers and families; 1c. Establish ongoing monitoring and data-management systems. 2. Train all healthcare workforce to support the policy. 3. Ensure women pregnant, in labour, and after birth know and understand key aspects of breastfeeding. 4. Help mothers initiate breastfeeding within one hour of birth, with skin-to-skin contact. 5. Show mothers how to breastfeed and how to maintain lactation if separated from infants. 6. No feeding of breastfed newborns any food or liquid other than breast milk unless medically indicated; no pacifiers or artificial teats, ensuring exclusive breastfeeding. 7. Enable mothers and babies to stay together 24 hours a day (rooming-in). 8. Encourage mothers to breastfeed on demand. 9. Advise mothers on feeding and use of expressed breast milk when separated. 10. When discharging mothers and babies, refer to care providers and support groups consistent with the policy. The steps are ordered from policy to discharge.
Advantages of breast-feeding. Breast milk gives optimal nutrition, immunoglobulins and lactoferrin, reduces NEC in preterms, promotes bonding, protects mothers from breast/ovarian cancer, and LAM can be used as temporary contraception.
Vitiligo. The diagnosis is vitiligo. Associated findings include Koebner phenomenon, leukotrichia, bright blue-white fluorescence under Wood’s lamp, and segmental versus non-segmental patterns; lesions are smooth, non-scaly and non-atrophic, and Wood’s lamp enhances contrast. Autoimmune associations such as thyroid disease, type 1 diabetes, alopecia areata, and occasional ocular/auditory involvement may be seen, with ocular associations including uveitis or retinal pigment changes and auditory association possibly sensorineural hearing loss. A distribution diagram would show periorificial and facial patches in non-segmental disease, unilateral dermatomal patches in segmental disease, acral spots, mucosal involvement, and diffuse universal depigmentation. Classification includes focal, segmental, mucosal, acrofacial, vulgaris and universal forms; non-segmental includes focal, acrofacial, vulgaris and mucosal, segmental is unilateral, and universal is extensive. Activity is scored with VASI and VETF. The course is progressive, stable, or spontaneously repigmenting, often from hair follicles; the progressive phase has new lesions, the stable phase has no spread, and repigmentation may be centripetal. Psychological impact is common, and better prognosis is linked to early age, facial lesions and recent onset. Thus, vitiligo is best described as an acquired depigmentation with variable distribution, activity, and prognosis.
What "Describe" is asking you to do
Give a full, ordered account of the thing named — its parts, stages or mechanism — in the sequence in which it actually exists or occurs. Most describe questions come from the science optionals, where the marks sit in correct technical detail and, where the stem says so, a labelled diagram.
Structure that answers it
One-line identification of the subject → the parts or stages in their real order, each with its defining detail → labelled diagram where the subject is structural → closing line on function or significance
Where marks are lost
Loose general prose where the examiner is ticking named parts, correct terminology and their sequence; and in the General Studies papers, turning to evaluation before the description is finished.
