Background: Infantile tremor syndrome (ITS) is a clinical syndrome of acute or gradual onset of mental and psychomotor changes, pigmentary disturbances of hair and skin, pallor, and tremors in malnourished children aged between 5 months and 3 years. It is a well-known entity, but the exact etiopathogenesis is still not known.
Setting and design: Prospective observational study carried out in the Department of Pediatrics at Dr RPGMC Tanda, Kangra in Himachal Pradesh.
Materials and methods: Demographic, clinical, and laboratory profile of 25 children with the diagnosis of preinfantile and ITS was collected who were admitted from May 2014 to June 2015.
Statistical analysis: Descriptive analysis was performed using SPSS 17 trial version.
Results: These children accounted for 0.5% of total pediatric admissions. Median, standard deviation age was 10, 3.1 months. Male to female ratio was 1.27:1. Cases were present throughout the year with two peaks observed in the months of May and November. This disease was found to be more common in higher birth order (68%). Complementary feeding, that too improper, was initiated in only 4 cases (16%). Ninety-six percent cases presented with comorbid illnesses. Respiratory tract infection was the most common association, followed by urinary tract infection. There was moderate anemia with dimorphic picture (40%). Thirteen (52%) had vitamin B12 levels below normal. Magnesium levels, though statistically insignificant (P = 0.8) were lower in patients with tremors.
Conclusion: This is a disease of multi-micronutrient deficiency, which can be present either alone or in association. Educating women about proper nutrition during pregnancy and timely administration of complementary feeding is of utmost importance.
