INTRODUCTION
Dengue is an endemic and epidemic disease of the tropical and subtropical regions. Between September & October 2012, there was an established outbreak of dengue in Hoskote, near Bangalore. Dengue results in serositis, which can be imaged by ultrasonography.
OBJECTIVE To correlate the USG findings with the serological tests in paediatric and adult patients.
MATERIALS AND METHODS 110 patients with clinical suspicion of dengue fever during the above period underwent serological tests-NS1, IgM and IgG and were evaluated with USG of the abdomen and thorax. The USG findings were correlated with serological tests.
RESULTS 67 Patients were seropositive, 43 were seronegative. The USG findings in seropositive paediatric patients (n=32) and adult patients (n=35) respectively were gall bladder (GB) wall edema-27 & 31, hepatomegaly-12 &14, ascites-16 & 12, splenomegaly-15 & 9, right pleural effusion-14 & 13, left and bilateral pleural effusion-7 & 5.
CONCLUSION In our study GB wall edema significantly correlated with seropositivity (p value=0.032). Thus ultrasound is an efficient screening tool in a case of dengue outbreak.
