Early postoperative bone scintigraphy in the evaluation of microvascular bone grafts in head and neck reconstruction.

Background: Bone scintigraphy was performed to monitor anastomotic patency and bone viability.

Methods: In this retrospective study, bone scans were carried out during the first three postoperative days in a series of 60 patients who underwent microvascular bone grafting for reconstruction of the mandible or maxilla.

Results: In our series, early bone scans detected a compromised vascular supply to the bone with high accuracy (p < 10-6) and a sensitivity that was superior to the sensitivity of clinical monitoring (92% and 75% respectively).

Early antiviral antibody response after immunization with viral oncolysate: a powerful prognostic marker for acute myelogenous leukemia remission patients.

Twenty-four acute myelogenous leukemia (AML) patients in first clinical remission received, as a part of their maintenance therapy, repeated injections of viral oncolysate (i.e., avian influenza virus-infected, formalin-inactivated, allogeneic leukemia cells).

Inverse correlation of antiviral antibody titers and the remission length in patients treated with viral oncolysate: a possible new prognostic sign in acute myelogenous leukemia.

In a study conducted since August 1974 by the Swiss Group for Clinical Cancer Research, 57 of 107 patients suffering from acute myelogenous leukemia achieved a complete remission. Thirty of these 57 patients were randomly selected to receive maintenance chemotherapy alone; the other 27 patients received, in addition to the same chemotherapy, monthly injections of viral oncolysate (i.e.
