Study Overview
Brief Summary
The use of local anaesthesia efficiently reduces pain due to needle puncture. However, when tuberculin skin test is performed it is the skin reaction to tuberculin injection that is studied. It is a quantitative skin reaction measured in millimiters. From the study of literature it is not known whether local anaesthetic modify skin reaction to tuberculin. Therefore, before recommending the use local anaesthesia for tuberculin intradermal injection we have to rule out a potential effect of local anaesthetic on the result of the test. This is particularly important in children, since there are more sensitive to pain than adults

Outcomes
Primary Outcomes
Measurement of tuberculin skin tests reaction performed with and without
local anaesthesia, in a child (intra subject reproducibility)
Secondary Outcomes
- influence of local anaesthesia use, on tuberculin skin test interpretation
- between observer reproducibility
- pain evaluation in child over 5 years of age between tuberculin skin tests performed with and without local anaesthesia
- relationship between local anaesthesia use and failure to perform a correct intradermal injection
- local tolerance to lidocaine / prilocaine
