RESUMO
A strain of mycoplasma not previously described has been isolated from the chorion, decidua, and amnion of a patient who sustained a spontaneous abortion during the middle trimester. The fetal membranes exhibited an inflammatory reaction, but no evidence of other infectious agents, bacterial or viral, was noted. The T strain identified is not a classical mycoplasma; it differs in growth and nutritional requirements from the T strains previously characterized.

A patient developed secondary acute myelogenous leukemia with a 20q- marker chromosome abnormality six years following chemotherapy and radiation for Hodgkins disease (HD). Routine cytogenetics on the bone marrow which had been harvested and cryopreserved immediately following completion of initial therapy for HD showed no cytogenetic abnormality. However, a 20q- clonal marker was detected after culturing bone marrow with hematopoietic growth factors (HGF). The marrow was used successfully for an autotransplant. Post-transplant, the 20q- marker was again detected in HGF cultured samples. The patient relapsed at 165 days post-transplant with the 20q- marker and trisomy 21. These data suggest that standard cytogenetic assays may not detect abnormal clones which can cause leukemia post-transplant.
