Abstract

Methods: This study was conducted in Paediatric Department Bacha Khan Medical College Mardan, from1st April 2010 to 31st March 2011. All patients presenting with fever having positive Widal test and/or positive culture for Salmonella were included. In total 36 consecutive patients were included and divided into two age groups, <5 years and >5years. The laboratory results of the two groups were compared. Recovery period and any complication in the two groups was also observed.

Results: Mean age of presentation was 5- (5.0±3.0) years. Male to female ratio was 2:1. Common laboratory features were Anemia (88%), elevated liver enzymes (85%), and elevated ESR (80%). Leucocytosis was more common in <5 years group while gallbladder sludge on USG was seen in 4 patients and all were >5 years (p=0.04). Complications were seen in 18.18% patients; of which 33.33% had serositis, 1 (16.67%) each had osteomylitis, synovitis, splenic abscess and shock. Majority (93.9%) recovered. 1 died and 1 was lost to follow up.
