C-G translocation in acute myelocytic leukemia with low neutrophil alkaline phosphatase activity.

A consistent chromosome abnormality of C-G translocation, t(8;21)(q22;q22), was found in 15 acute myelocytic leukemia (AML) patients with low neutrophil alkaline phosphatase (N-AP) activity. Granulocytes of these patients also had specific morphologic abnormalities. The bone marrow showed a tendency to relatively good maturation of leukemic cells for the disease AML. Clinical courses of the patients were mild and median survival was longer than that of patients with normal or high N-AP activity (p = 0.065, suggestive difference). Three out of six male patients with these type of AML had missing Y chromosome in addition to C-G translocation. The results suggest that specific cytogenetic abnormality of C-G translocation would be significantly associated with AML. Contrasting with low N-AP activity and the Philadelphia chromosome in chronic myelocytic leukemia, the findings in AML may offer additional evidence towards the possible relations between alkaline phosphatase activity and C or G chromosome.

Malignant lymphoma initiated with malabsorption syndrome due to Isospora belli infection and lymphocytosis.

A 47-year-old man had diarrhea in 1965. Four years later, malabsorption syndrome was diagnosed and the patient was found to have mild lymphocytosis. Abdominal lymphoma was suspected, but exploratory laparotomy was normal except for partial villous atrophy of small intestine and slightly enlarged mesenteric lymphnodes which were normal microscopically. In vitro lymphocyte blastformation with phytohemagglutinin was depressed markedly throughout the course and the result predicted the developement of malignancy of the lymphocytic system. Infection of Isospora belli was found thereafter, and sulfamethoxazole was quite effective for diarrhea. In August, 1974, he noticed cervical lymphadenopathy for the first time and it was diagnosed as undifferentiated type of malignant lymphoma. He died in December, 1974. In this case diarrhea was most probably caused by the intestinal infection of Isospora belli without obvious lymphoma. The symptom was swept away by peroral sulfamethoxazole. In this patient coccidiosis was presumably induced and prolonged by suppression of cellular immunity which might have already begun to progress at the onset of diarrhea.

Treatment of chronic osteomyelitis by transplantation of autogenous omentum with microvascular anastomosis. A preliminary report.

Free omental transplantation with vascular anastomosis was attempted in three clinical cases as a new method of treatment for chronic osteomyelitis. The bone cavity produced by debridement was completely eliminated by the transplanted omentum. Furthermore, the omentum, because of its biological characteristics, formed good vascular anastomoses with the adjacent bone tissue. Although sufficient time has not yet elapsed to prove the existence of healthy bone regeneration and therefore, further evaluation for a longer period is necessary, this therapeutic method would seem to have considerable potential in the treatment of chronic osteomyelitis.

Treatment of multiple myeloma and macroglobulinemai Waldenström: A long-term follow-up study.

Fifteen cases of multiple myeloma and 6 cases of macroglobulin emia Waldenstrom were followed up from 1957 to 1974. As for administration of drugs a low continuous dose regimen was mainly employed instead of a high intermittent dose regimen. 50% survival time from the onset of the disease was 18 months for multiple myeloma and 25 months for macroglobulinemia Waldenstrom. 3 cases of multiple myeloma are still living 44 months after the onset of symptoms. Cyclophosphamide and melphalan seem to have contributed much to the prolonged survival of these patients as well as improved supportive care.
