Concerns have been raised with regard to similarity of the article entitled "Diagnostic efficacy of adenosine deaminase levels in cerebrospinal fluid in patients of Tubercular meningitis: A comparison with PCR for Mycobacterium tuberculosis" with another article entitled "To compare CSF adenosine deaminase levels and CSF-PCR for tuberculous meningitis". The submitting and corresponding authors have been contacted and an investigation into these concerns is ongoing. Annals of Neurosciences will provide additional information as it becomes available.
