RESUMO
The meaning of the time from origin to first peak and from peak to peak of the derivative of the regional cerebral functions recorded after intravenous administration of a non-diffusible tracer is analyzed. Data obtained by cerebral and cardiac monitoring and evaluation of both times in patients with carotid thrombosis, indicates that the time from origin to first peak may be a better estimate of regional cerebral mode transit time than the time from peak to peak.

Thrombotic disease is one of the most relevant clinical problems for morbility and mortality. We can differentiate congenital and acquired forms. In this short communication we describe 1 case observed by us that seems interesting for the association of a congenital and acquired form [Protein S deficiency and inflammatory bowel disease (IBD)] and for the dramatic events suffered before receiving a complete diagnosis and therapy, indicating the importance of recollection of information from the patients, starting from anamnestic data.

Authors report about a case of Strongyloides stercoralis infestation. The patient, a 65-year old man, presented with a clinical history of eosinophilia but without symptomatology. Several stool specimen showed the presence of rhabditiform larvae of S. stercoralis and after therapy the patient had a normalization of the white blood ceIls count. The authors wish to point out the importance of the diagnosis because a change in immune status may convert a previously asymptomatic infection to hyperinfection.
