There was delayed introduction of complementary feeding in 63% of patients. 69% patients had severe vitamin B12 deficiency and 21% had moderate vitamin B12 deficiency.Conclusion: ITS, is commonly seen among male children belonging to lower socio-economic group among age group of 6 months to 24 months, presents with coarse tremors with moderate to severe anemia with moderate to severe acute malnutrition and is associated with deficiency of vitamin B12.
