Refers to viral meningitis, it is commoner than it is realised. It might be preceded by gastrointestinal complaints. On the other hand, it is possibly connected with a macular rash.
The features of viral meningitis are often less abrupt and milder than with urgent purulent meningitis. In order to make the distinction, it is very necessary for cerebrospinal fluid examination and culture. Seral viral titres, rectal swabs and nasopharyngeal have the possibility to recognise the virus.
In each case of aseptic encephalitis or meningitis, tuberculous meningitis must be thought. It follows the rupture of a tubercle into the cerebrospinal fluid and evolves as the resulting arteritis grows and inflammatory reaction. More attention should be paid that the cerebrospinal fluid examination is not usually diagnostic in early cases.
In seventy-five per cent, a tuberculin skin test is positive. On the other hand, in eight per cent , a chest X-ray indicates a suggestive lesion.Treatment is dealt with in the section dealing with tuberculosis. Moreover, as the diagnosis is just identified as any delay can be critical, treatment have to be began.
Neonatal meningitis is a very urgent illness. Group B haemolytic streptococci and Gram negative bacilli result in neonatal meningitis. It occurs one in every four thousand babies. Furthermore it has a high mortality. Most of survivors have many neurological sequelae.
Systemic treatment must be accompanied with medicines, for instance, cefotaxime or chloramphenicol, which are well-known to yield good concentrations in ventricular CSF. Therapy must be directed towards the ventriculitis which is always connected.
