The clinical and laboratory findings in a patient with uncontrolled gastrointestinal bleeding secondary to combined hemostatic defects (von Willebrand's disease and hemorrhagic telangiectasia) are described. Evidence for von Willebrand's disease was found in five family members, but no other affected relative was found to have hemorrhagic telangiectasia.(More)
Epinephrine infusion causes variable increases in the components of the Factor VIII (antihemophilic factor) complex in patients with von Willebrand's disease. The increase in antihemophilic factor procoagulant activity was greater than that of Factor VIII-related antigen and von Willebrand factor activity in two patients with von Willebrand's disease.(More)
The administration of mithramycin to patients with testicular tumors has been accompanied by a hemorrhagic diasthesis, often in the absence of thrombocytopenia. Bleeding time, platelet aggregation, platelet adenine nucleotide levels, and coagulation factor assays were studied in three patients receiving mithramycin for embryonal testicular carcinomas.

Patients at high risk of having thromboses can be identified not only on the basis of clinical criteria but also on the basis of laboratory studies. With use of a condensed coagulation profile consisting of six laboratory tests, the clinical impression of hypercoagulability can be confirmed in approximately 90 per cent of cases.
