- Idiopathic thrombocytopenia purpura
- Meningococcemia
- Rocky mountain spotted fever

- Syphillis
- Systemic lupus erythematosus
Diagnosis
Physical examination
Heart
- New murmer may suggest infective endocarditis
Laboratory Findings
- Labs include:
- ANA
- anti-dsDNA
- anti-SM antibodies
- Biopsy of lesions
- Blood cultures
- CBC
- Coagulation studies
- Peripheral smear
Chest X Ray
- X-ray for septic emboli
Echocardiography or Ultrasound
- Echo for endocarditis and valvular disorders
Treatment
Acute Pharmacotherapies
- Meningococcemia - IV antibiotics, antibiotic prophylaxis
Chronic Pharmacotherapies
