Meningitis

Meningitis — is inflammationmembranes of the brain or spinal cord with a consequent change of cerebrospinal fluid (CSF). Depending on the pathogen isolated meningitis:

  • serous (CSF transparent, with a large number of lymphocytes);
  • purulent (CSF is cloudy, with a large number of white blood cells).

The causes of serous meningitis most often the arenaviruses (cause of so-called lymphocytic choriomeningitis Armstrong), enteroviruses Coxsackie and ECHO, as well as agents of tuberculosis, brucellosis, syphilis, mumps (mumps) and influenza.

Purulent meningitis often becomes the result of meningococcal infection, as it may cause a negative staphylococci, streptococci, pneumococci, E. coli, Salmonella, Shigella, Proteus, listerelly.

Exciter can enter the body airborne or the fecal-oral way. Nemeningokokkovy purulent meningitis most often develops as a complication of inflammation of the ear or sinuses.

What is shown?

The manifestations of meningitis depends on the type of pathogen, but there are some common symptoms. They are:

  • fever;
  • headache;
  • seizures;
  • psychomotor agitation;
  • muscle tension spine (because of He, for example, you can not press your chin to the chest);
  • sometimes nausea and vomiting, blurred vision, photophobia.

Diagnostics

The diagnosis of meningitis puts infectious disease or a neurologist on the basis of relevant symptoms. Crucial to the study of the cerebrospinal fluid and the detection of the pathogen in it.

In some cases use PCR diagnostics (if other methods fail to identify the causative agent) Magnetic resonance tomography (if necessary to determine the location and nature of damage to the meninges).

Treatment

Treatment is directed from one side to the destruction of the pathogen (for this use antibiotics and other drugs) toother hand — to reduce toxicity and inflammation, reducing intracranial pressure.

If meningitis was a complication of ear infections or sinus, treatment is initiated with the removal of the primary purulent focus.
