Acute meningitis is clinically defined as a syndrome characterized by the appearance of meningeal signs. Meningeal symptoms include:
Fever, altered mental status, and neck stiffness
Fever, headache, and neck stiffness
Fever, headache, and altered mental status
Headache, altered mental status, and neck stiffness
Headache, nausea, vomiting, and seizures
Encephalitis is an inflammatory process involving the brain parenchyma accompanied by clinical neurological symptoms or abnormal neurological laboratory findings. The so-called encephalitis syndrome triad is:
Fever, altered mental status, and neck stiffness
Fever, headache, and neck stiffness
Fever, headache, and altered mental status
Headache, altered mental status, and neck stiffness
Headache, nausea, vomiting, and seizures
Encephalopathy is a generalized cerebral dysfunction without inflammation of the brain tissue. Causes of encephalopathy are NOT:
Alcohol poisoning
Hepatic failure
Severe hyperglycemia
Severe electrolyte disturbances
Bacterial infection.
A brain abscess is a focal intracerebral infection that begins as a localized area of cerebritis and progresses to a collection of pus surrounded by a capsule. The bacteria that most commonly cause brain abscesses are:
Streptococcus
Staphylococcus aureus
Pseudomonas
Mycobacterium tuberculosis
Escherichia coli
Cerebrospinal fluid (CSF) obtained from a lumbar puncture (LP) is required for various examinations. Because LP is an invasive and risky procedure, CSF specimens are usually collected only once for various examinations. Common routine examinations performed on CSF specimens to aid in the diagnosis of central nervous system infections include:
Leukocyte count, erythrocyte count, glucose level, protein level, Gram stain, bacterial culture
Leukocyte count, erythrocyte count, glucose level, protein level, Gram stain, viral PCR
Leukocyte count, India stain (negative stain), glucose level, protein level, Gram stain, bacterial culture
Leukocyte count, India stain (negative stain), glucose level, protein level, Gram stain, fungal culture
Leukocyte count, glucose level, protein level, Gram stain, bacterial culture, fungal culture
In the case of a central nervous system infection caused by BACTERIA, the most likely CSF laboratory test results are (normal CSF levels: cell count <5/mm3, protein=15-45 mg/dL, glucose 50-75 mg/dL):
Leukocyte count 100/mm3, mostly mononuclear cells, protein 90 mg/dL, glucose 60 mg/dL.
Leukocyte count 200/mm3, mostly mononuclear cells, protein 300 mg/dL, glucose 20 mg/dL.
Leukocyte count 2000/mm3, mostly polymorphonuclear cells, protein 90 mg/dL, glucose 60 mg/dL.
The leukocyte count is 2000/mm3, mostly polymorphonuclear cells, protein 200 mg/dL, glucose 20 mg/dL.
The leukocyte count is 2000/mm3, mostly mononuclear cells, protein 200 mg/dL, glucose 60 mg/dL.
In the case of a central nervous system infection caused by a VIRUS, the most likely laboratory test results for cerebrospinal fluid are:
Leukocyte count 100/mm3, predominantly mononuclear cells, protein 90 mg/dL, glucose 60 mg/dL.
Leukocyte count 200/mm3, predominantly mononuclear cells, protein 300 mg/dL, glucose 20 mg/dL.
Leukocyte count 2000/mm3, predominantly polymorphonuclear cells, protein 90 mg/dL, glucose 60 mg/dL.
Leukocyte count 2000/mm3, predominantly polymorphonuclear cells, protein 200 mg/dL, glucose 20 mg/dL.
The number of leukocytes is 2000/mm3, most of which are mononuclear cells, protein 200 mg/dL, glucose 60 mg/dL.
In the case of a central nervous system infection caused by FUNGUS, the most likely CSF laboratory test results are (normal CSF levels: cell count <5/mm3, protein=15-45 mg/dL, glucose 50-75 mg/dL):
Leukocyte count 100/mm3, predominantly mononuclear cells, protein 90 mg/dL, glucose 60 mg/dL.
Leukocyte count 200/mm3, predominantly mononuclear cells, protein 300 mg/dL, glucose 20 mg/dL.
Leukocyte count 2000/mm3, predominantly polymorphonuclear cells, protein 90 mg/dL, glucose 60 mg/dL.
The leukocyte count is 2000/mm3, mostly polymorphonuclear cells, protein 200 mg/dL, glucose 20 mg/dL.
The leukocyte count is 2000/mm3, mostly mononuclear cells, protein 200 mg/dL, glucose 60 mg/dL.
