Prosthetic valve endocarditis due to candida albicans treated successfully with medical treatment alone

Prosthetic valve endocarditis (PVE) caused by Candida species is associated with high morbidity and mortality. A combination of surgical resection and antifungal drug therapy is the golden standard for treatment, yet surgical intervention is not possible in all cases of Candida PVE. We report a case of PVE due to Candida albicans cured by medical treatment alone. This case suggests that, in some instances, Candida PVE can be managed medically with antifungal therapy. Such a conservative approach should be applied with caution and necessitates very close follow-up on a long-term basis.     

Treatment of acute lymphoblastic leukemia in adults by the modified protocol of L-10M (Sloan-Kettering)

We have treated 20 adult patients with acute lymphoblastic leukemia (ALL) and 2 patients with lymphoblastic lymphoma with a protocol modified from L-10M of the Memorial Sloan Kettering Cancer Center. Eighteen patients (81.8%) entered complete remission (CR). Eight of them eventually relapsed (only 1 patient had a meningeal relapse) and died. Median CR duration was 19 months (median overall follow-up of 35 months and 50% remission duration was not yet determined. Median overall survival was 19 months. Three patients died of sepsis during remission induction, but all of other deaths were due to resistant or relapsed leukemia. The four patients who completed 3.5 year's modified L-10M protocol were free from relapse for 6-11 months (mean 8.7). Although further follow-up is necessary, we suggest that modified L-10M protocol is effective for adult ALL and long-term survival may be available.     

Frequency of eosinophilia in adult T-cell leukemia/lymphoma.

Cases of adult T-cell leukemia/lymphoma (ATLL) display several peculiar clinical features, including skin rash, hypercalcemia, and an increase in the absolute neutrophil count. The patients rarely have pronounced eosinophilia. In this study, the eosinophilia observed in lymphoproliferative disorders of 62 patients with ATLL, 27 with T-cell lymphoma (TL), and 19 with B-cell lymphoma (BL) was investigated. The incidence of eosinophilia (greater than or equal to 570/microliters) was higher in patients with ATLL than in patients with TL or BL. Thirteen patients with ATLL (21.0%), 3 with TL (11.1%), and 2 with BL (10.5%) had eosinophilia. Of these patients, three with ATLL and one with TL who had a pathologic diagnosis of immunoblastic lymphadenopathy (IBL) showed pronounced eosinophilia up to 10,934/microliters. Because the number of eosinophils in the peripheral blood of these patients correlated both with the number of ATLL cells and the degree of lymphadenopathy and because this fluctuated with chemotherapy, it seems likely that the secretion of some lymphokines by the lymphoma cells is responsible for the eosinophilia.     

Chromosome 1 abnormalities at band 1p32 in two atomic bomb survivors with myelodysplastic syndrome

We reported on 2 atomic bomb survivors(a 60-year-old man and 63-year-old woman)suffering myelodysplastic syndrome(MDS) associated with 1p32 chromosomal abnormalities. They were exposed to atomic bomb radiation at distances of 1.2 and 1.1 km, respectively, and were given a diagnosis of MDS 44 and 46 years after the bombing, respectively. The male patient had refractory anemia(RA) and a bone marrow cell karyotype of 46, XY, del(1)(p22p32), t(8;11)(p11;p15). The female patient had RA with excess of blasts (RAEB) and a karyotype of 45, X, -X, t(1;11)(p32;q23), +del(1)(p32), inv(3) (p21q27), del(5)(q15), -6, -9, -19, +mar 1, +mar 2. Multi-separated nuclear megakaryocytes were observed in both patients. These findings suggested that they had been exposed to radiation near the atomic explosion despite the fact that their symptoms of MDS developed more than 40 years after the bombing. 1p32 is known to be the locus of the TAL1 gene. However, Southern blot analysis did not reveal rearrangement of the TAL1 gene in the male patient.
