We analysed a group of 390 patients, diagnosed with chronic lymphocytic leukaemia (CLL). Cases were subclassified as morphologically typical and atypical CLL according to the criteria of the FAB proposal. Typical CLL cases were mostly diagnosed at a low-risk stage (Binet A/Rai 0), required no immediate treatment and expected a long survival; atypical CLL cases mostly presented at a more advanced risk stage (Binet B/Rai I–II), usually required immediate treatment and their survival was shorter. Moreover, clinical staging was of prognostic significance in typical but not in atypical cases. In typical CLL, del(11q) was the most common chromosomal abnormality (21%) whereas in atypical CLL trisomy 12 was found in about 65% of the cases documented with an abnormal karyotype. Although chromosomal abnormalities were associated with a poor survival in typical CLL, they are of no prognostic significance in atypical CLL. Based on these data, we conclude that subtyping CLL by morphology enables the identification of two groups of cases, each characterized by a specific clinical presentation, different cytogenetic abnormalities and prognostic parameters. We speculate that these two groups may represent two related, but different, diseases with different prognostic parameters and a different survival. 相似文献

The clinical features, morphology and immunophenotype of 20 cases of B non Hodgkin's lymphoma (B-NHL) with chromosome abnormalities involving 11q13-14 were studied, to determine if this abnormality was closely associated with a specific sub-type of B-NHL. A t(11;14)(q13;q32) was found in 11 cases of intermediately differentiated lymphocytic lymphoma (IDLL). A breakpoint in the major translocation cluster of the BCL-1 locus was found in six of these cases. These patients were male with lymphomatous involvement of the bone marrow, marked splenomegaly and frequently had mucosa associated lymphoid tissue involvement. One patient with IDLL had a t(8;11)(p21;q13) and a rearranged BCL-1 locus, suggesting that this may be a variant of t(11;14)(q13;q32). Diagnoses of IDLL, chronic lymphocytic leukaemia, lymphoplasmacytic lymphoma and monocytoid B cell lymphoma were made in all but one of the remaining cases. These cases had either a translocation involving 11q13-14 and various partner chromosomes or an 11q13 deletion. This study demonstrates that 11q abnormalities occur mainly in a group of low-grade B-NHL of non follicle centre cell lineage. 相似文献

In Belgium, and in other OECD countries, there is a growing awareness about the importance of informal home care for the elderly’s well-being. Informal care is considered as an intrinsically valuable social phenomenon. Public authorities in Belgium have been advocating an active policy of support for informal carers. In 2007, an extensive survey was carried out in the Belgian municipality of Kruibeke in order to establish a better picture of the various needs of the elderly in their home situation, but also to better understand the way in which informal care is provided and perceived by care receivers and care givers. The study points to the need for support for the difficult burden of informal care and highlights the need for a coordinated and integrated approach to elderly care. 相似文献

Summary A voluntary insurance scheme for hospital care was launched in 1986 in the Bwamanda district in North West Zaire. The paper briefly reviews the rationale, design and implementation of the scheme and discusses its results and performance over time. The scheme succeeded in generating stable revenue for the hospital in a context where government intervention was virtually absent and external subsidies were most uncertain. Hospital data indicate that hospital services were used by a significantly higher proportion of insured patients than uninsured people. The features of the environment in which the insurance scheme thrived are discussed and the conditions that facilitated its development reviewed. These conditions comprise organizational-managerial, economic-financial, social and political factors. The Bwamanda case study illustrates the feasibility of health insurance — at least for hospital-based inpatient care - at rural district level in sub-Saharan Africa, but also exemplifies the managerial and social complexity of such financing mechanisms. 相似文献

A 13-year-old girl with chronic anaemia showed features of congenital dyserythropoietic anaemia (CDA) type II. The main clinical and haematological findings were splenomegaly, a mild microcytic anaemia, and numerous bizarre and binucleate normoblasts in the bone marrow. The acidified serum lysis test (Ham's test) performed with 5 normal sera was positive. The patient's red blood cells showed a markedly increased expression of the i red blood cell antigen. 相似文献

Influence of calcium, magnesium, sodium, potassium and pH on copper toxicity to barley (Hordeum vulgare) 总被引:1,自引:0,他引:1

The extent to which Ca(2+), Mg(2+), Na(+), K(+) ions and pH independently influence copper toxicity to barley (Hordeum vulgare) was assessed by measuring root growth in nutrient solutions. Increased Ca(2+) activity resulted in a sixfold decrease in [EC50(cu2+)] values, while a positive relationship between the cation activity and the EC50 was expected. Increased Mg(2+) activity resulted in a twofold increase in [EC50(cu2+)] values. Na(+), K(+) and H(+) activities did not significantly affect Cu(2+) toxicity. The obtained results indicated that competition for binding sites between Cu(2+) and cations such as Ca(2+), Mg(2+), Na(+), K(+) and H(+) is not an important factor in determining Cu(2+) toxicity to H. vulgare. However, the EC50s could, with one exception, be predicted within a factor three based on the free Cu(2+) activity, indicating that the free Cu(2+) activity cannot only be used to predict metal toxicity to aquatic, but also to terrestrial organisms. 相似文献

Improving access to hospital care for the poor: comparative analysis of four health equity funds in Cambodia 总被引:3,自引:0,他引:3

There is a large body of evidence that user fees in the health sector create exclusion. Health equity funds attempt to improve access to health care services for the poorest by paying the provider on their behalf. This paper reviews four hospital-based health equity funds in Cambodia and draws lessons for future operations. It investigates the practical questions of 'who should do what and how'. It presents, in a comparative framework, similarities and differences in objectives, the actors involved, design aspects and functional modalities between the health equity funds. The results of this review are presented along the lines of identification, hospitalization rates and relative costs. The four schemes had a positive impact on the volume of utilization of hospital services by the poorest patients. They now account for 7 to 52% of total hospital use. The utilization of hospitals by paying patients has remained constant in the same period. The comparative review shows that a range of operational arrangements may be adopted to achieve the health equity fund objectives. Our study identifies essential design aspects, and leaves different options open for others. 相似文献
