Asplenia and sickle cell disease

Complement deficiency

Alcoholism, IV drug use

HIV infection — immunocompromised; opportunistic pathogens

Recent infection

Crowding

Recent head trauma
Immunosuppression, diabetes mellitus, renal or adrenal insufficiency, cystic fibrosis, glucocorticoid excess

Recent travel to areas with endemic meningococcal disease such as sub-Saharan Africa

44
Q

N. Meninigitidis MC

A

Labs- ESR/CRP, CBC, CMP, Blood Cx.

lance that and obtain a wound cx

plain film and ultimately MRI

CT guided bx

46
