Typhoid fever and viral hepatitis.

Feco-oral route is the most common mode of transmission for both enteric fever and hepatitis A and E, and thus infection by these agents may occur concurrently especially in tropical endemic areas like India. In this scenario, there occurs a diagnostic dilemma with respect to differentiation from 'typhoid hepatitis', the hepatic manifestations of typhoid fever. We herein present such a case and discuss pertinent issues.

Comparison of axillary temperature with rectal or oral temperature and determination of optimum placement time in children.

The present study was done to compare axillary temperature (AT) with rectal temperature (RT) in 100 infants and with oral temperature (OT) in 100 children agd 6 to 12 years and also to find out the optimum placement time of the mercury thermometer at the above sites. Simultaneous AT and RT recording was done in infants while sequential AT and OT recording was done in older children by different investigators using calibrated Hick thermometers. The placement time recorded was when 3 consecutive readings at one minute interval remained unchanged. Significant correlation was observed between RT and AT (r=0.95, p <0.01) and between OT & AT (r = 0.97, p 0 <0.01). Equations were derived to calculate RT & AT from AT. The mean placement time for RT, AT and OT was 2.3 minutes, 4.8 minutes and 3.1 minutes respectively. The study showed a high degree of correlation between OT or RT and AT.

Reliability of perception of fever by touch.

OBJECTIVE: To assess the reliability of touch to predict fever in children. METHODS: 200 children who reported with fever formed the study material. Group I consisted of 100 children between 0-1 year of age and Group II consisted of 100 children between 6-12 years of age. Preterm, neonates under warming device, tachypnoeic and hypothermic were excluded from the study. The caregiver (CG) and the medical staffs (MS) response regarding presence or absence of fever by touch was noted in each child. Both were blinded to each other's response. Immediately temperature was recorded by calibrated rectal thermometer in Group I and calibrated axillary thermometer in Group II. RESULTS: The CG's touch had a sensitivity of 70.5% specificity of 40.9%, PPV of 38% NPV of 72.9%, PLR was 1.16 and NLR was 0.75. The MS's touch had a sensitivity of 78.0%, specificity of 63.6%, PPV of 38.0% NPV 84.8%, PLR of 2.08 and NLR of 0.36. There is over and under diagnosis of fever by both, the former being more by the CG reflecting the parental anxiety. The MS's touch is better to affirm or negative fever as compared to CG. The best site to palpate for presence of fever was abdomen, neck and forehead. CONCLUSION: Touch is not a valid screening test for fever. It is recommended that a thermometer must always be used by the MS to record fever and CG must be motivated for the same.
