Chronic hematuria and localized bladder damage following combined cyclophosphamide and local radiotherapy.

A 13-year-old white male had Ewing sarcoma of the right pubic and ischial bones. Initial therapy consisted of 5,400 rads in seven weeks to the right side of the pelvis and 14 intravenous injections of cyclophosphamide (Cytoxan, CTX) at 500 mg/m2; BCNU and Adriamycin maintenance therapy continued for a total of two years. He has now been disease-free for five years. Three months following the completion of the right pelvic radiotherapy (RT), while on intravenous CTX, severe hematuria appeared, which subsided, but at present he has continuous microscopic hematuria, as well as periodic episodes of gross hematuria. Serial cystocopies initially revealed thickening and hemorrhagic and edematous changes on the right (irradiated) side of the bladder, and recent multiple telangiectatic patches have been demonstrated as a late "healing" phase. This case demonstrates the additive toxicity to the bladder of CTX and RT, illustrating that the hemorrhagic cystitis can be extremely protracted lasting five years.

Antibodies to Epstein-Barr viral capsid and early antigens associated with Burkitt's lymphoma and lymphoblastic lymphosarcoma in Israel.

Before and/or after chemotherapy was administered to patients with Burkitt's lymphoma (BL) or lymphoblastic lymphosarcoma (LLS), their sera and those of matched controls were tested for antibodies to Epstein-Barr virus (EBV) capsid antigen (VCA) and early antigen by the indirect immunofluorescence method. Ten of the 16 BL patients were Arab children and 8 of the 11 LLS patients were Jews of Asian-African origin. Although half the BL patients did not have elevated antibody titers when their disease was diagnosed, significantly higher ones were detected in the BL group as compared with the LLS patients and their matched controls; Arab patients had the highest titers. IgM antibodies specific for VCA were found in 2 patients concurrently with elevated titers. We found no correlation between the clinical course of BL and the patients' antibody titers to EBV.

A family with red cell pyrimidine 5'-nucleotidase deficiency.

Congenital hemolytic anemia associated with pyrimidine 5'-nucleotidase deficiency is reported in two siblings. Both have had moderate chronic hemolytic anemia, splenomegaly, and jaundice since early infancy. The peripheral blood smear is characterized by striking red cell basophilic stippling. As this feature has been found in all previously reported cases, it should be the clue to the diagnosis.

Prophylactic central nervous system therapy in childhood acute lymphatic leukemia. Effect of poor-risk patients on the results.

The results of treatment in a group of 50 children with acute lymphatic leukemia are summarized. A comparison was made between those who received prophylactic central nervous systen (CNS) therapy on attaining complete remission and those who did not. Although none of the prophylactically treated children developed CNS leukemia, the expected prolongation of median complete remission time was not achieved. It was found that there was a high percentage of poor-risk patients in the CNS-treated group, and these patients relapsed early in the course of the disease. The prevention of CNS leukemia, a late complication of the disease, did not change the natural course of the disease in poor-risk patients. A need exists for new treatment protocols aimed at better control of the disease in these poor-risk cases.

Antibodies to Epstein-Barr virus in patients with Hodgkin's disease and leukemia.

Sera from 67 Hodgkin's disease patients, 71 leukemia patients, and 186 healthy subjects were tested for antibodies to Epstein-Barr (EB) viral antigens by immunofluorescence methods. In both disease categories, in particular Hodgkin's disease patients, levels of antibodies to the viral capsid antigen (EBV-VCA) and MGT were higher than in the healthy controls. Significantly higher titers were found in Jewish patients of Asian-African origin, as compared to Jews of European origin, with Arab patients as intermediates. The effect of ethnic origin was independant of age and histopathologic type. Sex had no effect on titer. Inconsistent differences in titer were found between age groups in the various ethnic-histopathologic type groups. Some of the leukemia patients had no detectable antibodies to EBV, while all Hodgkin's disease patients showed previous contact with EB virus. Antibodies to the early antigen (EBV-EA) were found in 27% of Hodgkin's and 37% of leukemia patients, and in none of the healthy controls tested.

A second Dr(a-) proposita with anti-Dra and a family with the Dr(a-) phenotype in two generations.

An Israeli Jewish woman who originated from the Uzbekskaya SSR in the south of the Soviet Union, had anti-Dra in her serum and her red cells were Dr(a-) as were those of three of her four children. All Dr(a-) red cells had weakened expression of their Cra, Tca, Esa, IFC, and other Cromer-related antigens. It is suggested that the Dr(a-) phenotype may result from inheritance of a dominant inhibitor gene, although a relatively common recessive allele of Dra was not excluded. Anti-Dra was inhibited by serums from the Dr(a+), but not the Dr(a-), members of the family.
