RESUMO

The aim of this study was to investigate sexual aggressors' perceptions of effectiveness of strategies to cope with high-risk situations and their reasons for not using the adaptive coping strategies they learned in treatment. A total of 32 sexual aggressors, incarcerated in a maximum security psychiatric institution, filled out the Coping Strategy Report daily for 2 months. A lack of will, ignorance, and an emotional disturbance were the most frequently reported reasons for not using adaptive coping strategies to deal with a negative mood, whereas anticipation of failure and emotional disturbance were most frequently reported with interpersonal conflicts. For deviant sexual fantasies, child molesters most frequently reported a lack of will and an anticipation of failure as justification for not using adaptive coping strategies, whereas sexual aggressors of women most frequently reported a lack of will and emotional disturbance. For negative moods and interpersonal conflicts, behavioral strategies, such as social skills, were reported to be the most effective. Cognitive strategies, such as covert sensitization, were reported to be most effective for coping with deviant sexual fantasies. Theoretical and clinical implications of these results are discussed.

RESUMO

Primary graft failure, secondary to either host-vs.-graft reaction or delayed engraftment, and graft-vs.-host disease (GVHD) are among the most difficult clinical problems to manage in the field of allogeneic bone marrow transplantation (BMT). Early diagnosis of both conditions would greatly improve their outcome. Using fluorescence in situ hybridization (FISH) with an X- and Y-probe mixture, we sequentially monitored chimerism of neutrophils and lymphoid cells from day 1 to 100 in 28 consecutive recipients of sex-mismatched unmanipulated bone marrow grafts. The objective was to quantitatively assess the evolution of chimerism during this crucial time interval and to determine whether chimerism patterns would be predictive of engraftment and GVHD. In recipients with primary graft failure (n=7), the presence of donor-type neutrophils and NK cells as well as the predominance of donor-type T cells distinguished patients who responded to G-CSF (n=5) from nonresponders (n=2). Furthermore, the clearance of host CD3+CD56- cells during days 5-10 posttransplantation was significantly hastened in patients who subsequently developed acute (delta=80%) or chronic (delta=81%) GVHD compared with patients without GVHD (delta=17%). Thus, our data suggest that molecular monitoring of the fate of host/donor hematopoietic cells in the early posttransplantation period could be useful in differentiating patients with delayed engraftment from those with irreversible rejection and in predicting the occurrence of GVHD as soon as day 10. This investigational approach may provide an appropriate basis on which to select adequate treatment for primary graft failure and high-risk candidates that could benefit from novel preemptive therapies for GVHD.

RESUMO

Using in situ hybridization with an X and Y chromosome probe mixture, we have sequentially studied peripheral blood samples from 10 patients (four males/six females) in an HLA-matched allogeneic setting in order to monitor the kinetics of early hematopoietic reconstitution. Interphase cells from smears consisting of purified granulocytic and lymphocytic populations respectively were studied in three patients at 24, 48, 72 and 96 h post-transplant. This period was arbitrarily defined as the immediate post-transplant period. These three patients plus seven others were studied sequentially at days 5, 10, 15, 20, 25 and 50 post-transplant, defined as the intermediate post-transplant period. The X and Y probes were indirectly labelled with rhodamine and fluoresceine isothiocyanate, respectively. Donor neutrophils were detected as early as 24 h post marrow infusion followed by a significant expansion at 48 h. At 96 h post-transplant, the median percentage of donor neutrophils was > 90%. In the immediate post-transplant period, most of the lymphocytes were of recipient origin. However, we have documented a significant expansion in donor lymphocytes, starting at day 5 post-transplant in most patients. Almost complete chimerism for the myeloid and lymphoid lineages was established at days 10 and 25 post-transplant, respectively. All patients engrafted normally according to standard clinical criteria. Follow-up data for those surviving > or = 100 days (eight patients), showed persistence of this pattern of hematopoietic reconstitution in all but one patient. Molecular monitoring of early engraftment has enabled us to unravel a distinct biphasic pattern of myeloid and lymphoid engraftment.

RESUMO

Refractory anemia (RA) is the only myelodysplastic syndrome (MDS) devoid of quantitative marrow diagnostic criteria. The diagnosis rests mainly on the subjective identification of qualitative abnormalities according to the French-American-British criteria (FAB) involving one or more bone marrow hematopoietic cell lineages. The occurrence of nonrandom chromosome abnormalities remains the hallmark of the disease and the only means of investigation which confirms the disease objectively. With the purpose in mind to further characterize RA among MDS, we have undertaken a prospective high resolution banding chromosome analyses of bone marrow cells in patients with primary refractory anemia (PRA) with the aim of defining a cytogenetic phenotype and of assessing the clinical relevance of clonal abnormalities at initial diagnosis. Of 39 patients consecutively referred for chromosome analyses with a diagnosis of RA according to the FAB criteria, 27 patients had PRA and fulfilled our criteria for adequate chromosome analyses. Median age was 68 years. Fourteen of 27 patients (52%) had clonal chromosomal abnormalities at diagnosis. None of the patients showed a complex karyotype; 9/14 (64%) had a mixture of normal and abnormal cells. Interstitial or terminal deletions, involving chromosomes 5, 6, 7, 9, 11, 12, and 20, were found in 11/14 (79%) of the patients. Comparison of survival between patients with and without abnormalities showed no difference. The presence of clonal abnormalities did not predict transformation to acute myeloblastic leukemia (AML) nor was it associated with poor survival. In this study, patients with PRA were found to have a predominant pseudodiploid karyotypic pattern characterized by interstitial and/or terminal deletions as opposed to derivatives, specific and non-specific balanced translocations, or other structural and numerical abnormalities. We were unable to reveal any prognostic significance to the presence of these clonal abnormalities at initial diagnosis.

RESUMO

Chromosome banding studies carried out on bone marrow cells from a 57-year-old white caucasian male with an M1 acute non-lymphocytic leukemia (ANLL) revealed an unbalanced translocation involving chromosomes 1 and 5 [der(5)t(1;5)(q23;q33)] as part of complex abnormalities in 76% of the cells analyzed. This chromosomal abnormality is the first to be reported in an adult patient with acute non-lymphocytic leukemia. A review of previous reports on translocations involving the juxtaposition of the 1q23----qter DNA segment to other chromosomes suggests that this new translocation may be specifically involved with abnormal myeloid proliferation.

RESUMO

Chromosome analyses were carried out on bone marrow cells from 43 consecutive patients with primary myelodysplastic syndromes (MDS), classified according to the French-American-British (FAB) cooperative group criteria. The objective was to evaluate the prognostic value of clonal chromosomal abnormalities and of an excess of blasts for early death from acute nonlymphocytic leukemia (ANLL) and/or bone marrow failure (BMF). Patients were subdivided into two main groups: (1) refractory anemia without an excess of blasts (RAWEB), grouping patients with refractory anemia (RA) and refractory anemia with ringed sideroblasts (RARS), and (2) refractory anemia with an excess of blasts (RAEB), grouping patients with refractory anemia with an excess of blasts (RAEB) and refractory anemia with an excess of blasts in transformation (RAEBt). There were 29 patients with RAWEB and 14 with RAEB. The median time of observation was 26 months for RAWEB and 12 months for RAEB. Ten RAWEB patients (34%) and 11 RAEB patients (78%) had clonal chromosomal abnormalities. Among the ten RAWEB patients with clonal abnormalities, one (10%) died from ANLL, while of 19 RAWEB patients with a normal karyotype, two (10%) died from ANLL or BMF. The median survival for patients with RAWEB and an abnormal karyotype was not reached. In contrast, eight of the 11 RAEB patients with clonal chromosomal abnormalities (74%) died from ANLL or BMF. The median survival in this sub-group was 7 months. By using a Cox proportional hazard regression analysis, it was determined that a karyotype abnormality was not a significant predictory of survival once the contribution of the RAWEB/RAEB variable was taken into account. Being in the RAEB group was associated with a relative risk of 10.6 of dying from ANLL or BMF (beta = 2.36, standard error (SE) = 0.68, P = .0001). We conclude that classifying patients according to an excess of blasts will lead to a better prediction of survival than determining karyotype abnormality.

RESUMO

From January 1983 to January 1985, we have found a deletion of the long arm of chromosome 5 (5q-) in the bone marrow cells of 8 patients; they represent consecutive patients referred to our institution for investigation and treatment of the following hematological disorders in whom the 5q- abnormality was found: acute nonlymphocytic leukemia (ANLL) (3), refractory anemia with excess blasts (RAEB) (2), preleukemia (PL) (1), sideroblastic anemia (SA) (1), refractory anemia (RA) (1). The deletion proved to be interstitial in all patients, with 3 different breakpoint patterns emerging: q13q33, q11.2q21, q11.2q33. Proximal breakpoint q11.2 was found only in patients with an initial diagnosis of ANLL. The common region deleted in all patients was comprised between bands q13q21. The clinical relevance and biological meaning of the heterogeneity of proximal and distal breakpoints found in this study are discussed.
