Bacterial Meningitis — The Importance of Cerebro-Spinal Fluid Examination

The role of lumbar puncture in bacterial meningitis has been debated in recent years, especially in the presence of worsening headache, alteration of conscious level, focal neurological signs, papilloedema or a haemorrhagic rash.
