A 26-year-old patient with acute lymphatic leukemic conceived while on systemic chemotherapy. This patient experienced relapse during the second trimester, and a second complete hematologic remission was achieved with doxorubicin hydrochloride, vincristine, and prednisone. A 2400-gram, but otherwise normal, male infant was delivered by Caesarean section(More)
This report describes a patient with carcinoid metastatic to the liver in whom a hepatic artery catheter was placed for infusion therapy. This resulted in a previously unreported complication of a hepatic artery-biliary fistula. The clinical presentation of this complication and mode of management are described. The etiologic factors responsible for this(More)
Two patients with aplastic anemia evolving from cellular bone marrows with severely diminished megakaryocytes are reported. During this evolution a plasma inhibitor of in vitro granulocyte-macrophage colony formation was demonstrated associated with non-A, non-B hepatitis in one patient. The second patient had abnormal liver function that corrected after(More)
Two patients with multiple myeloma with large retroperitoneal myelomatous masses are discussed. This extraosseous extension of disease caused obstructive uropathy in both patients. This complication has not been previously recognized in multiple myeloma and must be added to the potential casues of renal failure in this disease.
Forty-two patients with Stage IV carcinoma of the breast were treated with an oral program of combination chemotherapy consisting of three drugs: methotrexate, 5-fluorouracil, and cyclophosphamide (substituting 1, 3-bis (2-chloroethyl)-1-nitrosourea in cases with central nervous system involvement). Sixty-four percent of the patients responded to the(More)
We examine opportunistic evolution, a variation of master-slave distributed evaluation designed for deployment of evolutionary computation to very large grid computing architectures with limited communications, severe evaluation overhead, and wide variance in evaluation node speed. In opportunistic evolution, slaves receive some N individuals at a time,(More)
