Abstract
BACKGROUND Diabetes insipidus due to leukemic involvement of the central nervous system has been described previously in several patients. Although the timing of the diabetes insipidus onset in relation to the leukemia is variable, it has not been described previously as the first manifestation of leukemia relapse. METHODS Two cases of leukemia relapse presenting as central diabetes insipidus are described and the literature is reviewed. RESULTS Clinical data of 29 of the 39 reported cases were available. The median age was 46 years, with no gender predominance. Seventy-three percent had acute nonlymphocytic leukemia, and deletion of chromosome 7 or monosomy 7 was the predominant cytogenetic abnormality. No temporal relation between the onset of diabetes insipidus and the leukemia was found. In none of the previously reported cases was diabetes insipidus the first manifestation of the leukemia recurrence. CONCLUSIONS The temporal relationship between diabetes insipidus and leukemia is inconsistent. The former may precede, follow, or present concomitantly with the latter. Two cases of diabetes insipidus as the presenting sign of leukemia relapse are reported.

Abstract
The distribution of three immunoglobulin heavy chain variable region gene subgroups (VH1, 3 and 5) was investigated, using the polymerase chain reaction technique, in 53 patients with chronic lymphocytic leukemia. Thirty-seven patients displayed rearrangements of one of the above three gene segments. Over-representation of the VH5 subgroup was observed relative to its small size.

Abstract
We describe two kindreds of Arab ancestry characterized by multiple cases of acute lymphoblastic leukemia. Consanguinity and intermarriages were prevalent in the two families. Age, mode of presentation, characteristics of the leukemic cells, response to treatment and prognosis were remarkably similar among the patients. A short review of the literature on familial leukemia is given.

Abstract
Immunocytologic analyses of bone marrow can provide clinically useful prognostic information in neuroblastoma. While analyzing the bone marrow with a panel of monoclonal antibodies, which detect neuroblasts and other defining B-, T-, and myloid lineage, we identified two infants with stage IV-S neuroblastoma whose bone marrow contained a large population of common acute lymphoblastic leukemia (ALL)-like cells. This population expressed HLA-DR, CD19(B1), CD10(CALLA), and occasionally CD20(B1). Since 1988, 17 additional patients with advanced neuroblastoma (IV-S, III, and IV) were studied by us. In 10 of the 19 patients, the bone marrow revealed an expanded CD10 population (20-70%). It appears that this group of patients has a better prognosis. Out of 9 patients who did not have an expanded CD10 population, 8 died within 9 months from diagnosis, whereas out of 10 patients with an expanded CD10 population only one died and the others are alive, 6-30 months from diagnosis (P < 0.001). An expanded CD10 population in the bone marrow of disseminated neuroblastoma patients may therefore serve as a prognostic factor. Apart from the prognostic value of this particular population in the single patient, its presence may shed light on the interrelationship between the immune system and the neuroendocrine compartment.

Abstract
In the last 4 years, 24 cases of neuroblastoma were treated in the Pediatric Hematology-Oncology Unit at the Chaim Sheba Medical Center, 8 of whom were under 1 year of age. Four of them were the product of a pregnancy-induced or preserved by gonadotropins, clomiphene citrate, or progestational hormones. These drugs are known to produce a higher than normal level of estradiol or progesterone in the early stages of pregnancy. Our observation led to the hypothesis that high levels of progestational hormones given during pregnancy are a risk factor for neuroblastoma in infancy.

Abstract
Chronic lymphocytic leukaemia (CLL) is known to be a stable monoclonal neoplasm. In contrast to early studies demonstrating no more than two hybridizing immunoglobulin heavy chain bands corresponding to the two expected alleles, we have demonstrated an unexpected multiband pattern when the HindIII-digested DNA samples from 38 CLL patients were analysed by Southern blot hybridization using JH and C mu gene probes. In order to characterize the genetic basis for the multiband pattern, we molecularly cloned the immunoglobulin heavy chain genes of one of the patients whose leukaemic DNA sample demonstrated three hybridizing JH bands and a loss of the germline band. The cloned rearranged immunoglobulin genes could be divided, based on the restriction mapping and the hybridization with the various probes, into two basic patterns representing two alleles. In one of the cloned rearranged immunoglobulin genes a secondary rearrangement occurred that resulted in the addition of 300 base-pair long sequence into the switch region, and the creation of a HindIII restriction site. The results of the study suggest that clonal evolution occurs in some CLL, and that many of these neoplasms are indeed oligoclonal due to the accumulation of secondary genetic changes.

Abstract
The disease manifestations, response to therapy, and follow-up course of 35 patients with essential thrombocythemia seen in a single center were evaluated. The median age was 53 years (range 17-81). Twelve patients were asymptomatic on presentation and the diagnosis was incidental. Twenty-three patients presented with thrombocytosis-related symptoms, most commonly neurological, microcirculatory, or thromboembolic. In no patient did hemorrhage occur as a presenting symptom. The mean platelet count (+/- SD) at diagnosis was 858 +/- 223 x 10(9)/l and the mean maximal count during the follow-up period was 989 +/- 269 x 10(9)/l. The median follow-up of the entire group was 54 months (range 12-172). Ten of the 12 patients who were asymptomatic on presentation remained so during the observation period, while 10 patients who presented with thrombocytosis-related symptoms became asymptomatic following a single course of treatment with no recurrence of symptoms. Thirty of the 35 patients were treated with busulfan or hydroxyurea or both. Response to cytoreductive therapy was prompt and continuous in most patients. Essential thrombocythemia might be a disease of grave consequence but it seems that in general its course under treatment is more benign than previously thought.

Abstract
Monoclonal gammopathies are disorders in which a clone of lymphocytes arising from a common ancestor cell proliferates and secretes a monoclonal antibody. Electrophoresis of plasma proteins is used as a diagnostic test for these disorders. It produces a narrow peak within the zone of gammaglobulins, corresponding to the monoclonal antibody. On rare occasions electrophoresis produces 2 narrow peaks simultaneously, suggesting the existence of 2 monoclonal antibodies, establishing a biclonal gammopathy. We present 4 such patients with biclonal gammopathy. The prevalence of mono- and biclonal gammopathies in the general population ranges between 1-3%, but only 1% of these are biclonal. Patients with biclonal gammopathy do not differ clinically from those with monoclonal gammopathy. Theoretically, pathogenesis of biclonal gammopathies might involve true biclonicity: 2 separate transformations in 2 precursor cells. Alternatively, the 2 transformed clones might have originated from a common ancestor cell early in differentiation, prior to immunoglobulin gene rearrangement; in this case pseudobiclonicity could be implied. The question of true biclonicity versus pseudobiclonicity has been examined by others using statistical analysis of isotypic combination distributions of heavy and light chains. The incidence of identity of the light chain isotype in both monoclonal antibodies (44%) was higher than would be expected in a random distribution (27%). In a study of the 2 monoclonal immunoglobulins, the identity of the amino acid sequences of the variable site was demonstrated, suggesting a common ancestor. In another research, anti-idiotypic antibodies suggested a common idiotype in the 2 proteins. Immunofluorescent labeling of bone marrow cells produced conflicting evidence of biclonicity in several studies.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Bladder involvement by extramedullary plasmacytoma is a rare condition. A 46-year-old woman with known IgA-lambda multiple myeloma who developed this condition is described. The patient suffered from massive hematuria, which led to hypovolemic shock. Prompt supportive treatment by blood transfusions, fulguration of the bleeding mucosa and continuous bladder irrigation stopped the bleeding. Subsequent bladder irradiation lead only to partial response of the tumor.

Abstract
We describe 4 male children infected by the human immunodeficiency virus (HIV) who developed Burkitt's lymphoma during their disease. The clinical picture was characterized by an insidious appearance of symptoms. All the children suffered for several months from abdominal discomfort and a gradual elevation of their blood lactic dehydrogenase (LDH) level prior to diagnosis. Bone marrow involvement was found in 2 of the patients and jaw involvement in the other 2. After confirming the diagnosis of Burkitt's lymphoma, they were treated according to conventional protocols, with no need to reduce the dose intensity. They all went into complete remission and did not suffer from major opportunistic infections during chemotherapy. None of them relapsed. Two patients died from opportunistic infections 1 and 3 years after diagnosis. The other 2 are alive, 7 years and 6 months after diagnosis. The various characteristics of this unique pediatric group are described and the comparison of the clinical picture in adults is made, together with a review of the relevant literature.

Abstract
Immunophenotyping of bone marrow mononuclear cells of 2 infants with stage IV-S neuroblastoma revealed the presence of many lymphoblasts and immature lymphocytes. Immunophenotyping showed that a high percentage of bone marrow cells were positive for the HLA-DR, CD19, CD20 and CD10 phenotype, similar to common acute lymphoblastic leukemia cells. Within 6 months of follow-up, without any treatment, complete regression of the tumors was observed. The coexistence of these two unusual populations will be discussed.

Abstract
We studied the clinical efficacy and safety of the antifibrinolytic drug tranexamic acid (TA) in patients undergoing chemotherapy for acute leukemia. 54 newley diagnosed AML patients were treated with 1 g of TA every 6 hours until the platelet count rose to above 20 x 10(9)/l. Platelet transfusions were given, irrespective of the count, only when oral, mucosal or significant skin bleeding manifestations were observed. During induction, the average number of days with thrombocytopenia below 20 x 10(9)/l was 14.4 +/- 7.4 and 4.6 +/- 4.1 transfusions were given in each course. During consolidation, the average number of thrombocytopenic days was 8.4 +/- 8.5 and only 1.7 +/- 1.8 transfusions were administered. In 11.5% of the induction and 32.1% of the consolidation courses, no platelet support was required. TA was tolerated very well and no side effects or thromboembolic complications were observed. Only in 6 of the 78 induction courses did a major bleeding event occur and there were none in any of the 53 consolidation courses. Thus it seems that TA therapy allowed a significant reduction in the use of platelet transfusions without submitting the patients to greater bleeding risks.

Abstract
Since 1984, 47 patients with untreated acute myeloid leukemia (AML) were hospitalized in a special hematology unit for aggressive chemotherapy. Complete remission was obtained in 68%, 15% died of complications of treatment (infections and bleeding) and 15% had refractory leukemia. The actuarial survival after 3 years for patients in remission was 43%. No patients with refractory leukemia lived more than 1 year. The actuarial remission at 3 years of 21 patients who received additional courses of aggressive chemotherapy (consolidation treatment) was 42%, as opposed to 11% in 11 patients who received maintenance treatment. The 47 patients received 108 courses of aggressive chemotherapy including 47 for induction of remission. During 86 courses (80%) the patients developed fever and in 33 blood cultures were positive; during 16 courses a fungal infection developed. The most common bacterial infection was by E. coli. During the first induction treatment 5 patients died of sepsis and 1 of cerebral hemorrhage. None died during consolidation therapy. During the year preceding the opening of the unit, 12 AML patients were treated on regular medical wards, and five (42%) achieved a complete remission, while 6 died of complications during the first course of induction chemotherapy. Our findings are in line with those of similar units, which indicates the importance of special nursing units for the treatment of acute leukemia.
