In this contribution Lepidasthenia loboi sp.

Comparison of the predictive ability of two scoring systems for the diagnosis of tuberculosis in children.

Unlabelled: Diagnosing childhood tuberculosis requires a strong diagnostic suspicion due to its paucibacillary manifestation. Different scoring systems and algorithms have been developed to deal with such challenge skillfully. These include the Keith Edwards diagnostic score and Stegen's criteria modified by Toledo (Stegen-Toledo).
