ABSTRACT
Background: Typhoid fever still continues to be a major public health problem in Nepal. A clinical spectrum of typhoid varies widely. It causes significant complication as well as mortality. A simple, reliable, affordable and rapid diagnostic test has been a long felt need of the clinicians to prescribe specific medication, adopt prevention of the emergence of antibiotics resistance and overall reduce the disease burden in the community.Methods: The prospective descriptive study was performed in 125 children between 2 years to 15 years of age admitted to the Pediatrics Department from September 2017 to September 2018. Blood culture, Typhidot rapid IgM were performed. MEDCALC software was used to calculate 95% confidence interval for sensitivity, specificity, predictive value positive, predictive value negative and accuracy. Kappa test was used to determine the agreement between Typhidot IgM and blood culture methods.Results: The study consisted of 125 children with acute febrile illness for more than 3 days with clinical symptomatology, consistent with typhoid fever. The reliability of Typhidot IgM in relation with blood culture and the study lighten that sensitivity 92.3% (95% CI: 63.9, 99.8), specificity 49.1% (95% CI: 39.5, 58.7), PPV 17.4% (95% CI: 14.2, 21.1), NPV 98.2% (95% CI: 89.2, 99.7) and accuracy 53.6% (95% CI: 44.5, 62.6). The two methods i.e. Typhoid IgM and blood culture shows significant agreement with p value 0.004.Conclusions: The present study demonstrates that Typhidot IgM has all the attributes of an ideal screening test.
ABSTRACT
Background: Urine analysis by dipstick is a useful tool to identify children with asymptomatic renal diseases. Dipstick urinalysis screening was conducted in asymptomatic school children to detect prevalence of renal disease.Methods: A cross sectional study was carried out in 862 children of age 6 to 15 years studying in different schools of Birgunj, Nepal between January 2019 to June 2019. First morning mid-stream urine samples were obtained from students and tested by dipstick method. Children with abnormal findings were re-tested after fifteen days.Results: Ninety-six (11.13%) children had urinary abnormalities at the first screening; 8 children had specific urinary abnormalities after second screening. 4 children had urinary tract infection, followed by glomerulonephritis, type 1 diabetes, hydronephrosis and nephrotic syndrome. Urinary abnormalities were more common in females than in males.Conclusions: Asymptomatic urinary abnormalities are detected by urine screening program at school age. Further work-up reveals the specific diagnosis and effective interventions help reduce the renal disease in future.
