		 History
		
 This child presented at the age of three months with a one-week history of irritability 
and crying. A lumbar puncture grew S. pneumoniae; there was no response to therapy and the 
child died three days after admission. The child suffered Down's syndrome and at autopsy 
congenital atrial septal defect was demonstrated. Histological examination of tissues showed 
evidence of a terminal disseminated intravascular coagulation.
