“Evaluation of a mathematical model proposed to predict the diagnosis of tuberculosis in children with cervical lymph node enlargement”.

The differential diagnosis between TB and NTB lymphadenitis is still a clinical challenge because a definitive cultural diagnosis is not always achievable. Moreover, microbiological analyses still requires a long time for definitive results, and a delayed diagnosis is associated with an increased risk of disseminated disease. Indeed, the proposed model still deserve attention due to its possible ability in suggesting a hard diagnosis in a easy, rapid, noninvasive and non-expensive way, but it needs to be improved by multicentric studies based on national scale.
