Q

what is the diagnosis for meningitis?

A
  • Initial diagnosis of meningitis can be made by clinical examination followed by a lumbar puncture.
  • The diagnosis is supported or confirmed by growing the bacteria from specimens of cerebrospinal fluid or blood,
  • usually cannot be safely cared for at home.

Q

what are the main objectives of surveillance for meningitis?

A
  • detect and confirm outbreaks;
  • monitor the incidence trends, including the distribution and evolution of serogroups and serotypes;
  • estimate the disease burden;
  • monitor the antibiotic resistance profile;
  • monitor the circulation, distribution, and evolution of specific strains (clones)
  • estimate the impact of meningitis control strategies, particularly preventive vaccination programmes.

Q

what are the tests for CSF leaks?

A

CT scan, MRI scan, cisternogram
Can see where the radioactive substance is leaking out= cisternogram

17
Q

what are the causes of CSF leaks?

A

90% due to injury, 10% spontaneous (Ehlers Danlos and Marfan
syndromes)
* Problems with connective tissue that stretch and tear causing a leak
* Genetic influence may lead to leaks

18
Q

what is the prevention for CSF leaks?

A

Non-preventable and unpredictable
Cant determine whether the leaks are going to occur

19
Q

what is the treatment for CSF leaks?

A

Mostly non-direct conservative treatment of rest and time. In some cases, surgery and ‘blood patches.
* Can live with it but need to lie down a lot to alleviate the headaches immediately- soon as stand up may start again.
