    Background Lymphopenia and tumor-associated macrophages are negative prognostic factors for survival in classical Hodgkin’s lymphoma. We, therefore, studied whether the peripheral blood absolute lymphocyte count/absolute monocyte count ratio at diagnosis affects survival in classical Hodgkin’s lymphoma. Design and Methods We studied 476 consecutive patients with classical Hodgkin’s lymphoma followed at the Mayo Clinic from 1974 to 2010. Receiver operating characteristic curves and area under the curve were used to determine cut-off values for the absolute lymphocyte count/absolute monocyte count ratio at diagnosis, while proportional hazards models were used to compare survival based on the absolute lymphocyte count/absolute monocyte count ratio at diagnosis. Results The median follow-up period was 5.6 years (range, 0.1–33.7 years). An absolute lymphocyte count/absolute monocyte count ratio at diagnosis of 1.1 or more was the best cut-off value for survival with an area under the curve of 0.91 (95% confidence interval, 0.86 to 0.96), a sensitivity of 90% (95% confidence interval, 85% to 96%) and specificity of 79% (95% confidence interval, 73% to 88%). Absolute lymphocyte count/absolute monocyte count ratio at diagnosis was an independent prognostic factor for overall survival (hazard ratio, 0.18; 95% confidence interval, 0.08 to 0.38, P<0.0001); lymphoma-specific survival (hazard ratio, 0.10; 95% confidence interval, 0.04 to 0.25, P<0.0001); progression-free survival (hazard ratio, 0.35; 95% confidence interval, 0.18 to 0.66, P<0.002) and time to progression (hazard ratio, 0.27; 95% confidence interval, 0.17 to 0.57, P<0.0006). Conclusions The ratio of absolute lymphocyte count/absolute monocyte count at diagnosis is an independent prognostic factor for survival and provides a single biomarker to predict clinical outcomes in patients with classical Hodgkin’s lymphoma.

    Immune evasion plays a central role in the pathophysiology of classical Hodgkin lymphoma (cHL). As mutations of the CD58 gene contribute to immune evasion of diffuse large B cell lymphoma tumor cells, we studied whether alterations of the CD58 gene also occur in Hodgkin and Reed/Sternberg (HRS) cells of cHL. Single nucleotide polymorphism chip analysis revealed homozygous deletions within the CD58 gene in two cHL cell lines (SUP-HD1 and U-HO1). Sequencing of the CD58 gene in seven cHL cell lines disclosed in addition a homozygous splice site mutation in cell line KM-H2. None of the three mutated lines expressed CD58 protein on their surface. Thus, three of seven cHL cell lines analyzed harbor destructive CD58 mutations. Molecular analysis of isolated HRS cells from 10 primary cases of cHL; however, did not reveal any case with a CD58 mutation. A FICTION study indicated heterozygous deletions of CD58 in 3 of 13 cHL analyzed. Overall, we report frequent inactivating mutations of CD58 in cHL cell lines, but their rare occurrence in primary HRS cells. As the three cHL cell lines with CD58 mutations were all established from HRS cells located in pleural effusions, i.e., outside the normal lymph node microenvironment, in end-stages of the disease, CD58 inactivation in cHL might be predominantly prevalent to such situations.

    Lymphocyte-depleted classical Hodgkin lymphoma (LDCHL) is the rarest entity among the classical Hodgkin lymphoma (CHL) subtypes, accounting for <1% of CHL cases in Western countries. Similarly, primary splenic Hodgkin lymphoma is a rare diagnosis among all cases of lymphomatous involvement of spleen. Representing a combination of these two rare entities is the primary splenic LDCHL, with only one case reported in the literature. Here, we report second case of primary splenic LDCHL with a unique presentation. The patient was a 60-year-old Caucasian HIV-negative woman with a history of extranodal pleuropulmonary marginal zone lymphoma (MZL) treated with rituximab who presented with new-onset splenomegaly. Splenectomy revealed large number of Hodgkin/Reed-Sternberg cells (CD15+, CD30+, PAX5+ and EBER+) with the background consisting of histiocytes and smaller number of lymphocytes and eosinophils. There was no evidence of nodal or other extranodal site involvement. Thus, in addition to being a very rare entity, this case also provides an additional point of interest: the disease arose in the backdrop of previous diagnosis of extranodal pleuropulmonary MZL successfully treated with rituximab. We discuss the potential implications. PMID:26193900

    The hierarchy of classical Chinese poetry has been broadly acknowledged by a number of studies in Chinese literature. However, quantitative investigations about the evolution of classical Chinese poetry are limited. The primary goal of this study is to provide quantitative evidence of the evolutionary linkages, with emphasis on word usage, among different period genres for classical Chinese poetry. Specifically, various statistical analyses were performed to find and compare the patterns of word usage in the poems of nine period genres, including shi jing, chu ci, Han shi , Jin shi, Tang shi, Song shi, Yuan shi, Ming shi, and Qing shi. The result of analysis indicates that each of nine period genres has unique patterns of word usage, with some Chinese characters being preferably used by the poems of a particular period genre. The analysis on the general pattern of word preference implies a decreasing trend in the use of ancient Chinese characters along the timeline of dynastic types of classical Chinese poetr...

    2011-01-01

    Classical Hodgkin lymphoma (CHL) is a relatively uncommon B cell-derived neoplasm that presents with rare malignant cells in an abundant reactive background. The diagnosis of CHL currently relies on a combination of morphologic findings and immunohistochemical stains. With the exception of rare cases with dramatically increased malignant populations, isolation of pure viable tumor cells has not been historically possible. Recently, a reliable flow cytometric assay for direct detection and isolation of the malignant cells in this disease has been developed. This assay has proven useful diagnostically and has been clinically validated to have a very high sensitivity and nearly absolute specificity for the diagnosis of CHL in routine clinical samples. This paper describes the methodology for the flow cytometric detection of CHL in clinical samples as well as current state of evaluation of background lymphocytes as an adjunct diagnostic test. Also discussed are exciting research applications of the direct isolation of viable tumor cells in CHL. The current state of flow cytometric evaluation of nodular lymphocyte predominant Hodgkin lymphoma and T cell-rich large B cell lymphoma is also briefly discussed. PMID:21127714

    Classical Hodgkin lymphoma (CHL) and nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) are considered separate entities with different prognosis and treatment. However, morphologic features can be similar and immunohistochemical studies are essential in the distinction; thus, determination of additional biomarkers is of utmost importance. LRF/Pokemon is a proto-oncogene, an interacting partner co-expressed with BCL6 in germinal centers and highly expressed in diffuse large B-cell lymphoma and follicular lymphoma. Conversely, loss of the LRF gene in mouse hematopoietic stem cells results in complete block of early B cell development with concomitant Notch de-repression, indicating its critical role in B versus T cell fate decision at the hematopoietic stem cell stage. For the first time, we show that LRF/Pokemon is predominantly expressed in NLPHL cases as is BCL6 with low to absent NOTCH1 protein expression; while Hodgkin Reed-Sternberg (HRS) cells in CHL show low to absent BCL6 and LRF/Pokemon expression with higher NOTCH1 expression. We illustrate a potential functional interaction between LRF and BCL6 in NLPHL pathogenesis, and differential expression of LRF/Pokemon and NOTCH1 proteins in CHL thus showing differential expression, making for an additional diagnostic marker and therapeutic target.

    Hodgkin’s disease (HD) is a lymphoproliferative disease of predominantly B-cell origin. However, the reasons for the incomplete development of the B-cell phenotype and lack of immunoglobulin expression in classical HD (cHD) have not been fully explained. We examined the expression of PU.1 in HD, an Ets-family transcription factor, which regulates the expression of immunoglobulin and other genes that are important for B-cell development. Immunohistochemistry for PU.1 was performed on 35 cases of cHD and 15 cases of lymphocyte predominance HD as well as 67 non-Hodgkin’s lymphomas (NHL). Expression of PU.1 was studied by Western blotting in four cHD-derived cell lines and in five NHL cell lines. We also studied the expression of two additional B-cell transcription factors, B-cell-specific activator protein and Oct-2. Our results show a striking lack of PU.1 expression by neoplastic cells in cHD but not in lymphocyte predominance HD. Our study also confirmed that B-cell-specific activator protein but not Oct-2 is not expressed by cHD. Western blotting showed no PU.1 protein expression in the cHD-derived cell lines, with the exception of one cell line of putative monocyte/histiocyte origin. The lack of PU.1 protein expression in cHD likely contributes to the lack of immunoglobulin expression and incomplete B-cell phenotype characteristic of the Reed-Sternberg cells in cHD.

    The current study aimed to assess the economic burden of progressive disease among patients with Hodgkin lymphoma (HL) receiving second- or third-line therapy in a large US network of community-based practices. This retrospective, observational cohort analysis used electronic health records to examine adult patients with classical HL who received chemotherapy between 2007 and 2011. Of 291 observations, 112 had non-progressive disease (received only one line of therapy; LOT1), 114 received second-line therapy (LOT2), and 65 received third-line therapy (LOT3). In LOT2, 49 patients (43%) underwent transplant. In LOT3, 13 patients (20%) underwent transplant. The mean total cost per line of therapy was $21 956 in LOT1, $77 219 in LOT2, and $59 442 in LOT3. When transplant was required, the mean total cost per line of therapy increased 7- to 8-fold when compared with the cost of LOT1 (approximately $154 000 for LOT2 and $193 000 for LOT3). Future therapies that intervene as early as possible in the treatment algorithm to prevent or significantly delay relapse will likely result in significant cost savings. PMID:25860233

    Ferritin levels might correlate with disease activity in classical Hodgkin lymphoma (cHL). We analyzed the prognostic significance of the ferritin value at diagnosis in 173 cHL patients treated with ABVD between 2003 and 2013. The 5-year overall survival (OS) and progression-free survival (PFS) probabilities were 80% and 64%, respectively. Patients with ferritin ? 350 ?g/l [high ferritin group (HF), n = 62] were more likely to have advanced stage disease, B-symptoms and higher International Prognostic Score (IPS) compared with patients with ferritin < 350 ?g/l [low ferritin group (LF), n = 111]. The complete remission (CR) rate and 5-year PFS and OS probabilities were lower in HF vs. LF patients (69% vs. 89%, p = 0.025; 40% vs. 78%, p < 0.001; 61% vs. 90%, p = 0.001; respectively). Multivariate analysis revealed that advanced stage (p = 0.001) and ferritin levels ? 350 ?g/l (p = 0.002) were independent predictors for PFS. In conclusion, the ferritin level at diagnosis is a useful prognostic marker for cHL. PMID:25860241

    Background The inflammatory infiltrate plays a pivotal role in classical Hodgkin lymphoma (cHL). Here, we focussed on the role of macrophages (M?) and dendritic cells (DC). Methods M? and DC infiltration was investigated in 106 cHL specimens using immunohistochemistry and cytokine expression was analyzed in a subset by real-time PCR. Human peripheral blood-derived monocytes, DC, M? stimulated with GM-CSF (M?GM-CSF, pro-inflammatory M?-1-model) or M-CSF (M?M-CSF, immunomodulatory M?-2-model) were incubated with cHL cell line (L1236, HDLM2) supernatants (SN). DC maturation or M? polarization were investigated by flow cytometry. Furthermore, the impact of DC or M? on cHL cell proliferation was analyzed by BrdU/CFSE assay. Results In cHL tissues mature myeloid (m)DC and M? predominated. High numbers of CD83+ mDC and low numbers of CD163+ M? were associated with improved disease specific survival. In numerous cHL specimens increased levels of both pro- and anti-inflammatory cytokines and of IL13 and GM-CSF were observed compared to reactive lymphadenopathies. Maturation of DC and induction and maintenance of an immunomodulatory M? phenotype were promoted by SN derived from cHL cell lines. TNF? neutralization in SN resulted in a significant inhibition of mDC maturation. DC and pro-inflammatory M? inhibited the proliferation of cHL cells. Conclusion Adopting an immunomodulatory phenotype is a potential mechanism for how M? promote immune evasion in cHL. Mature DC, in contrast, might participate in antitumoral immunity. PMID:25470820

    Epstein-Barr virus (EBV) is detected in the tumor cells of some but not all Hodgkin lymphoma (HL) patients, and evidence indicates that EBV-positive and –negative HL are distinct entities. Racial/ethnic variation in EBV-positive HL in international comparisons suggests etiologic roles for environmental and genetic factors, but these studies used clinical series and evaluated EBV presence by differing protocols. Therefore, we evaluated EBV presence in the tumors of a large (n=1,032), racially and sociodemographically diverse series of California incident classical HL cases with uniform pathology re-review and EBV detection methods. Tumor EBV-positivity was associated with Hispanic and Asian/Pacific Islander (API) but not black race/ethnicity, irrespective of demographic and clinical factors. Complex race-specific associations were observed between EBV-positive HL and age, sex, histology, stage, neighborhood socioeconomic status (SES), and birth place. In Hispanics, EBV-positive HL was associated not only with young and older age, male sex, and mixed cellularity histology, but also with foreign birth and lower SES in females, suggesting immune function responses to correlates of early childhood experience and later environmental exposures, respectively, as well as of pregnancy. For APIs, a lack of association with birth place may reflect the higher SES of API than Hispanic immigrants. In blacks, EBV-positive HL was associated with later-stage disease, consistent with racial/ethnic variation in certain cytokine polymorphisms. The racial/ethnic variation in our findings suggests that EBV-positive HL results from an intricate interplay of early- and later-life environmental, hormonal, and genetic factors leading to depressed immune function and poorly controlled EBV infection.

    According to the data of the recent archaeological excavations, the history of traditional Chinese medicine begins in the neolithic period (10,000-4,000 years ago). The fundamental principles of the traditional Chinese medicine may be interpreted on the basis of two classic theories of Chinese thought: the Yin-Yang theory and the five phases theory. The former stated that our reality is the product of the continuous interaction and transformation of the Yin and Yang principles. The latter recognise the existence of five emblematic groups in which everything regarding humankind and nature may be classified. The five phases interact in two different ways: the cycle of production (Sheng) and the cycle of control (Ke). Theoretical basis of traditional Chinese medicine are described on the Huangdi Neijing (The Book of Yellow Emperor's: a classic of internal medicine) written during the period 475-225 b.C. as a dialogue between the mythical Emperor Huangdi and his physician Qibo. The book is divided into two parts: the Suwen (Questions about living matter) and Lingshu (The vital axe). Each part is composed of 81 sections. In this book are set correspondences between phases and organs, viscera, feelings, body fluids, flavours, foods, colours, and so on. We can also find the description of blood (Xue) and energy (Qi) circulation and the pathways of main, collateral and curious vessels. The origins of disease are also reported on the Huangdi Neijing. As regards the psychological point of view, special attention is dedicated to dreams and their possible causes and to the description of various kind of mental illness. The unknown Authors underline the five defects and the four mistakes of the physician, pointing out the importance to avoid them. Finally, it must be mentioned their special care to the principles of preventive medicine. PMID:9446158

    BCL-6 is essential for germinal center formation and thus for affinity maturation of immunoglobulin (Ig) genes by somatic mutations. The 5'-noncoding region of the BCL-6 gene is even a target for the mutation machinery. Translocations of the BCL-6 gene to heterologous promoters and mutations of its 5'-noncoding regulatory region were reported to be potential mechanisms for deregulating BCL-6 expression and for playing a role in the genesis of non-Hodgkin lymphoma. In line with this hypothesis is the observation that B-cell lymphoma with somatic mutations, such as diffuse large B-cell lymphoma and follicular lymphoma, also carry BCL-6 mutations, some of which are recurrently detectable. Classic Hodgkin disease (cHD) is also derived from B cells with high loads of somatic mutations and thus a further candidate for BCL-6 mutations. To determine the presence and potential role of BCL-6 mutations in cHD, the 5'-noncoding BCL-6 proportion of single Hodgkin and Reed-Sternberg (HRS) cells from 6 cases of cHD and 6 cases of HD-derived cell lines was analyzed. All B-cell-derived HD cases and cell lines harbored BCL-6 mutations. In contrast, both T-cell-derived HD cases and cell lines were devoid of BCL-6 mutations. With only one exception, there were no lymphoma-specific recurrent BCL-6 mutations detected, and BCL-6 protein was absent from the HRS cells of most cases. In conclusion, (1) somatic BCL-6 mutations are restricted to cHD cases of B-cell origin, and (2) the BCL-6 mutations represent mostly irrelevant somatic base substitutions without consequences for BCL-6 protein expression and the pathogenesis of cHD.

    2015-03-12

    Treatment of Hodgkin lymphoma is associated with 2 major types of risk: that the treatment may fail to cure the disease or that the treatment will prove unacceptably toxic. Careful assessment of the amount of the lymphoma (tumor burden), its behavior (extent of invasion or specific organ compromise), and host related factors (age; coincident systemic infection; and organ dysfunction, especially hematopoietic, cardiac, or pulmonary) is essential to optimize outcome. Elaborately assembled prognostic scoring systems, such as the International Prognostic Factors Project score, have lost their accuracy and value as increasingly effective chemotherapy and supportive care have been developed. Identification of specific biomarkers derived from sophisticated exploration of Hodgkin lymphoma biology is bringing promise of further improvement in targeted therapy in which effectiveness is increased at the same time off-target toxicity is diminished. Parallel developments in functional imaging are providing additional potential to evaluate the efficacy of treatment while it is being delivered, allowing dynamic assessment of risk during chemotherapy and adaptation of the therapy in real time. Risk assessment in Hodgkin lymphoma is continuously evolving, promising ever greater precision and clinical relevance. This article explores the past usefulness and the emerging potential of risk assessment for this imminently curable malignancy. PMID:25575542

    Deregulated transcription factor (TF) activities are commonly observed in hematopoietic malignancies. Understanding tumorigenesis therefore requires determining the function and hierarchical role of individual TFs. To identify TFs central to lymphomagenesis, we identified lymphoma type-specific accessible chromatin by global mapping of DNaseI hypersensitive sites and analyzed enriched TF-binding motifs in these regions. Applying this unbiased approach to classical Hodgkin lymphoma (HL), a common B-cell–derived lymphoma with a complex pattern of deregulated TFs, we discovered interferon regulatory factor (IRF) sites among the top enriched motifs. High-level expression of the proinflammatory TF IRF5 was specific to HL cells and crucial for their survival. Furthermore, IRF5 initiated a regulatory cascade in human non-Hodgkin B-cell lines and primary murine B cells by inducing the TF AP-1 and cooperating with NF-?B to activate essential characteristic features of HL. Our strategy efficiently identified a lymphoma type-specific key regulator and uncovered a tumor promoting role of IRF5. PMID:25288773

    The outcome of classical Hodgkin lymphoma (cHL) patients may be related to the tumor microenvironment, which in turn may be influenced by Epstein-Barr virus (EBV) infection. To characterize the cHL microenvironment, a set of 63 cHL tissue samples was profiled using DNA microarrays. Their gene expression profile differed from that of histiocyte T cell-rich B-cell lymphoma (H/TCRBCL) samples that were used as controls, mainly due to high expression of PDCD1/PD-1 in H/TCRBCL. EBV(+) cHL tissues could be distinguished from EBV(-) samples by a gene signature characteristic of Th1 and antiviral responses. Samples from cHL patients with favorable outcome overexpressed genes specific for B cells and genes involved in apoptotic pathways. An independent set of 146 cHL samples was analyzed using immunohistochemistry. It showed a significant adverse value in case of high percentage of either TIA-1(+)-reactive cells or topoisomerase-2(+) tumor cells, whereas high numbers of BCL11A(+), FOXP3(+), or CD20(+) reactive cells had a favorable influence. Our results suggest an antitumoral role for B cells in the cHL microenvironment and a stronger stromal influence of the PD1 pathway in H/TCRBCL than cHL. The observation of Th1/ antiviral response in EBV(+) cHL tissues provides a basis for novel treatment strategies. PMID:19096012

    We studied by immunohistochemistry the background CD20 + cells in 131 cases of classical Hodgkin lymphoma (cHL). High CD20 + dispersed cells (CD20BG) showed a significant correlation with longer overall survival (OS) and a trend toward improved progression-free survival (PFS). At multivariate analysis high CD20BG was also an independent prognostic factor of improved PFS and OS. The prognostic role of CD20BG seems to be opposite with respect to tumor associated macrophages (TAMs) we studied previously in most cases of the series. We scored patients on the basis of the respective CD20BG and TAM count and found that the combination of low CD20BG and high TAMs was related to a significantly reduced PFS and OS at univariate and multivariate analysis. Microenvironment CD20 + cells seem to play a favorable prognostic role in cHL. Depletion of CD20 + cells together with an increase of TAMs identifies a group of patients with high-risk disease.

The maturation and differentiation of tissue macrophages depends upon interactions between colony-stimulating factor 1 receptor (CSF1R) and its ligands. There remains, however, a lack of consistent information on CSF1R expression in TAMs. A new monoclonal antibody, FER216, was generated to investigate CSF1R protein distribution in formalin fixed tissue samples from 24 reactive lymphoid tissues and 187 different lymphoma types. We also analysed the distribution of CSF1R+, CD68+ and CD163+ macrophages by double immunostaining, and studied the relationship between CSF1R expression and survival in an independent series of 249 cHL patients. CSF1R+ TAMs were less frequent in B-cell lymphocytic leukaemia and lymphoblastic B-cell lymphoma than in diffuse large B-cell lymphoma, peripheral T-cell lymphoma, angioimmunoblastic T-cell lymphoma and cHL. HRS cells in cHL and, with the exception of three cases of anaplastic large cell lymphoma, the neoplastic cells in NHLs, lacked detectable CSF1R protein. A CSF1R+ enriched microenvironment in cHL was associated with shorter survival in an independent series of 249 cHL patients. CSF1R pathway activation was evident in the cHL and inactivation of this pathway could be a potential therapeutic target in cHL cases. PMID:26066800

    Thymus and activation-regulated chemokine (TARC) has been identified as a lymphocyte-directed CC chemokine that attracts activated T-helper type 2 (Th2) cells in humans. Recent studies showed that the T cells surrounding Reed-Sternberg cells in Hodgkin's lymphomas (HL) are Th2 type. Anaplastic large cell lymphomas (ALCL), T-cell-rich B-cell lymphoma (TCRBCL) can mimic HL in some instances. This study aimed to establish the pattern of TARC expression in these diseases. Immunohistochemical stain using a polyclonal goat anti-human antibody to TARC was performed on 119 cases of confirmed HL; 99 were classical type (43 mixed cellularity, 43 nodular sclerosis, 5 lymphocyte depleted, 4 lymphocyte rich, 4 unclassifiable) and 20 lymphocyte predominant HL. Additional 27 ALCL (9 T-, 18 null-cell phenotype), 16 T-cell and 8 B-cell non-Hodgkin's lymphoma (NHL) were studied. A total of 85.8% of the classical HL, one case of ALCL, and one case of large cell B-cell lymphoma with anaplastic morphology showed positive TARC expression in the tumor cells. The expression was paranuclear and/or diffuse in the cell cytoplasm. The tumor cells in all cases of lymphocyte predominant HL, TCRBCL, null ALCL, and T-NHL did not express TARC. The high frequency of TARC expression in the Reed-Sternberg cells of classical HL may explain the characteristic T-cell infiltrate in this disease. The absence in other types that may be morphologically similar indicates that staining for TARC may aid in differential diagnosis. PMID:11420464

    Macrophages have been implicated in the pathogenesis of classical Hodgkin lymphoma (cHL) and have been suggested to have a negative impact on outcome. Most studies addressing the role of macrophages in cHL have relied on identification of macrophages by generic macrophage antigens, e.g., CD68. We have therefore conducted an in situ analysis of macrophage polarization in a series of 100 pediatric cHL (pcHL) cases using double staining immunohistochemistry, combining CD68 or CD163 with pSTAT1 (M1-like) or CMAF (M2-like). M1- or M2-polarised microenvironment was defined by an excess of one population over the other (>1.5). Expression of STAT1 and LYZ genes was also evaluated by RT-qPCR. Patients <14 years and EBV+ cases displayed higher numbers of CD68+pSTAT1+ cells than older children and EBV- cases, respectively (P=0.01 and P=0.02). A cytotoxic tumor microenvironment, defined by a CD8+/FOXP3+ ratio >1.5 was associated with higher numbers of CD68+pSTAT1+ (P=0.025) and CD163+pSTAT1+ macrophages (P<0.0005). Levels of STAT1 and LYZ expression were associated with the numbers of CD68+pSTAT1+ macrophages. EBV+ cHL cases disclosed a predominant M1 polarized microenvironment similar to Th1 mediated inflammatory disorders, while EBV- cHL showed a predominant M2 polarized microenvironment closer to Th2 mediated inflammatory diseases. Better overall-survival (OS) was observed in cases with higher numbers of CD163+pSTAT1+ macrophages (P=0.02) while larger numbers of CD163+CMAF+ macrophages were associated with worse progression-free survival (PFS) (P=0.02). Predominant M1-like polarization as disclosed by CD163+pSTAT1+/CD163+CMAF+ ratio > 1.5 was associated with better OS (P= 0.037). In conclusion, macrophage polarization in pcHL correlates with prevalent local T cell response and may be influenced by the EBV-status of neoplastic cells. Besides, M1-like and M2-like macrophages displayed differential effects on outcome in pcHL. PMID:25978381

    Classical Chinese Poetry (CCP) is a valuable but almost locked treasure chest of human wisdom and civilization since 2000 years. With the advent of the Web 2.0 a renaissance of CCP is possible even outside Chinese-speaking communities world-wide. With mobile technologies and educational games we can address new learning communities for CCP and open the chest again. In this paper, we introduce a Web 2.0 personal learning environment for CCP. We have developed a generic and interoperable data model for CCP we utilize not only for mobile learning scenarios but also for educational gaming with different levels of difficulty. Learners are empowered to learn Chinese poetry, language, history, and culture. This research work shows how modern information technologies assist users to diffuse knowledge across the borderlines of communities and societies.

    Background: Hodgkin Reed-Sternberg (HRS) cells may promote differentiation of CD4+ naïve T cells toward both FoxP3+ T regulatory (Treg) cells and TIA-1+ cytotoxic T lymphocytes (CTL). Previous studies suggest that an overabundance of cytotoxic TIA-1+ cells in relation to FoxP3+ T reg cells portends unfavorable outcomes in classical Hodgkin lymphoma (cHL), raising the possibility that its pathogenesis may be related to immune dysregulation. Sirt1 deacetylates FoxP3 and leads to decreased Treg functionality. Our objective was to compare Sirt1 and FoxP3 expressions in Hodgkin lymphoma infiltrating lymphocytes (HLIL) and confirm Sirt1 expression in HRS cells. Design: Immunohistochemical staining of paraffin-embedded tissue with antibodies to Sirt1, FoxP3, TIA-1, and CD8 was performed. Expression of Sirt1was assessed in both the HRS cells and in the HLILs in twenty-four cases. Adequate tissue was available in 13 cHL cases to permit the enumeration of FoxP3, TIA-1 and CD8 by giving their percent staining of HLILs. Results: In HLILs, nuclear expression of Sirt1 was 32-88% (mean 67%); FoxP3 expression was 9-40% (mean 23.9%); TIA-1 expression was 15-87% (mean 32%); and CD8 expression was 10-45% (mean = 31%). Sirt1 to FoxP3 ratio was 0.96-5.5 (mean 3.2). TIA-1 to FoxP3 ratio was 0.6-5.1 (mean 1.6). CD8 to FoxP3 ratio was 0.43-3.7 (mean 1.5). There was a difference of Sirt1 to FoxP3 ratios between remission and recurrence groups, being significantly higher in the recurrence group (P = 0.005). Sirt1 demonstrated high nuclear expression in the HRS cells of 21 out of 24 (88%) cases analyzed. Conclusion: The relative overexpression of Sirt1 to FoxP3 in HLILs may be considered possible targets for immune modulation. Histone deacetylase inhibitors may increase the efficacy of existing treatment regimens by downregulating SIRT1 gene mRNA/Sirt1 protein function and together with rapamycin could expand the T regulatory/FoxP3 population and functionality and improve prognosis for remission in cHL. Targeting Sirt1 in the HRS cells may facilitate their ability to promote naïve T cell differentiation toward Treg cells over CTL. PMID:26722524

    Prospective studies conducted in Western populations have suggested that alterations in soluble CD27 (sCD27) and soluble CD30 (sCD30), two markers indicative of B-cell activation, are associated with risk of non-Hodgkin lymphoma (NHL). Given that the characteristics of NHL in East Asia differ from the West and mechanistic commonalities between these populations with respect to the role of intermediate endpoint biomarkers in lymphomagenesis have not been explored, we conducted a pooled nested case-control study from three prospective studies of Chinese men and women including 218 NHL cases and 218 individually matched controls. Compared with the lowest quartile, ORs (95% CIs) for the second, third and fourth quartiles of sCD27 were 1.60 (0.83-3.09), 1.94 (0.98-3.83) and 4.45 (2.25-8.81), respectively (p(trend) = 0.000005). The corresponding ORs for sCD30 were 1.74 (0.85-3.58), 1.86 (0.94-3.67) and 5.15 (2.62-10.12; p(trend) = 0.0000002). These associations remained statistically significant in individuals diagnosed with NHL 10 or more years after blood draw. Notably, the magnitude of the associations with NHL risk was very similar to those in Western populations in previous studies. These findings of the similar association between sCD27 or sCD30 and NHL risk across different populations support an important underlying mechanism of B-cell activation in lymphomagenesis.

    2014-01-01

    Hodgkin’s lymphoma is a lymphoid tumour that represents about 1% of all de novo neoplasms occurring every year worldwide. Its diagnosis is based on the identification of characteristic neoplastic cells within an inflammatory milieu. Molecular studies have shown that most, if not all cases, belong to the same clonal population, which is derived from peripheral B-cells. The relevance of Epstein-Barr virus infection at least in a proportion of patients was also demonstrated. The REAL/WHO classification recognizes a basic distinction between nodular lymphocyte predominance HL (NLPHL) and classic HL (CHL), reflecting the differences in clinical presentation, behavior, morphology, phenotype, molecular features as well as in the composition of their cellular background. CHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, mixed cellularity and lymphocyte depleted. Despite its well known histological and clinical features, Hodgkin’s lymphoma (HL) has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics and possible mechanisms of lymphomagenesis.

    Text mining and other literature-based investigations can assist in identifying natural products for experimental and clinical research. This article details a method for systematically analyzing data derived from the classical Chinese medical literature. We present the results of electronic searches of Zhong Hua Yi Dian ("Encyclopaedia of Traditional Chinese Medicine"), a CD of 1000 premodern (before 1950) medical books, for single herbs, and other natural products used for dementia, memory disorders, and memory improvement. This review explores how the terminology for these disorders has changed over time and which herbs have been used more or less frequently, and compares the results from the premodern literature with the herbs indexed for memory disorders in a modern pharmacopoeia. The searches located 731 citations deriving from 127 different books written between ca. 188 ad and ca. 1920. Of the 110 different natural products identified, those most frequently cited for forgetfulness were yuan zhi (Polygala tenuifolia), fu shen (Poria cocos), and chang pu (Acorus spp.), all of which have been cited repeatedly over the past 1800 years and appear among the 31 herbs indexed in a modern pharmacopoeia. By providing a complete, hierarchically organized list of herbs for a specific disorder, this approach can assist researchers in selecting herbs for research. PMID:23433049

    Background An inefficient immune response against Epstein-Barr virus (EBV) infection is related to the pathogenesis of a subgroup of classical Hodgkin lymphomas (cHL). Some EBV immune-evasion mechanisms target HLA presentation, including the non-classical HLA-E molecule. HLA-E can be recognized by T cells via the TCR, and it also regulates natural killer (NK) cell signaling through the inhibitory CD94/NKG2A receptor. Some evidences indicate that EBV-infected B-cells promote the proliferation of NK subsets bearing CD94/NKG2A, suggesting a relevant function of these cells in EBV control. Variations in CD94/NKG2A-HLA-E interactions could affect NK cell-mediated immunity and, consequently, play a role in EBV-driven transformation and lymphomagenesis. The two most common HLA-E alleles, E*01:01 and E*01:03, differ by a single amino acid change that modifies the molecule function. We hypothesized that the functional differences in these variants might participate in the pathogenicity of EBV. Aim We studied two series of cHL patients, both with EBV-positive and-negative cases, and a cohort of unrelated controls, to assess the impact of HLA-E variants on EBV-related cHL susceptibility. Results We found that the genotypes with at least one copy of E*01:01 (i.e., E*01:01 homozygous and heterozygous) were underrepresented among cHL patients from both series compared to controls (72.6% and 71.6% vs 83%, p = 0.001). After stratification by EBV status, we found low rates of E*01:01-carriers mainly among EBV-positive cases (67.6%). These reduced frequencies are seen independently of other factors such as age, gender, HLA-A*01 and HLA-A*02, HLA alleles positively and negatively associated with the disease (adjusted OR = 0.4, p = 0.001). Furthermore, alleles from both HLA loci exert a cumulative effect on EBV-associated cHL susceptibility. Conclusions These results indicate that E*01:01 is a novel protective genetic factor in EBV-associated cHL and support a role for HLA-E recognition on the control of EBV infection and lymphomagenesis.

    Gray zone lymphoma (GZL) with features between classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL) is a recently recognized entity reported to present primarily with mediastinal disease (MGZL). We examined detailed clinical features, outcomes, and prognostic factors among 112 GZL patients recently treated across 19 North American centers. Forty-three percent of patients presented with MGZL, whereas 57% had non-MGZL (NMGZL). NMGZL patients were older (50 versus 37 years, P?=?0.0001); more often had bone marrow involvement (19% versus 0%, P?=?0.001); >1 extranodal site (27% versus 8%, P?=?0.014); and advanced stage disease (81% versus 13%, P?=?0.0001); but they had less bulk (8% versus 44%, P?=?0.0001), compared with MGZL patients. Common frontline treatments were cyclophosphamide-doxorubicin-vincristine-prednisone +/- rituximab (CHOP+/-R) 46%, doxorubicin-bleomycin-vinblastine-dacarbazine +/- rituximab (ABVD+/-R) 30%, and dose-adjusted etoposide-doxorubicin-cyclophosphamide-vincristine-prednisone-rituximab (DA-EPOCH-R) 10%. Overall and complete response rates for all patients were 71% and 59%, respectively; 33% had primary refractory disease. At 31-month median follow-up, 2-year progression-free survival (PFS) and overall survival rates were 40% and 88%, respectively. Interestingly, outcomes in MGZL patients seemed similar compared with that of NMGZL patients. On multivariable analyses, performance status and stage were highly prognostic for survival for all patients. Additionally, patients treated with ABVD+/-R had markedly inferior 2-year PFS (22% versus 52%, P?=?0.03) compared with DLBCL-directed therapy (CHOP+/-R and DA-EPOCH-R), which persisted on Cox regression (hazard ratio, 1.88; 95% confidence interval, 1.03-3.83; P?=?0.04). Furthermore, rituximab was associated with improved PFS on multivariable analyses (hazard ratio, 0.35; 95% confidence interval, 0.18-0.69; P?=?0.002). Collectively, GZL is a heterogeneous and likely more common entity and often with nonmediastinal presentation, whereas outcomes seem superior when treated with a rituximab-based, DLBCL-specific regimen.

    According to the WHO classification, Hodgkin's lymphoma (HL) is subdivided into a classical variant and a nodular lymphocyte predominant variant which are characterized by the presence of Hodgkin's and Reed-Sternberg (H-RS) cells or lymphocytic and histiocytic (L&H) cells, respectively. This article reviews genetic characteristics and transcriptional changes of H-RS and L&H cells, including recent knowledge about transforming mechanisms and signaling pathways that contribute to the antiapoptotic phenotype displayed by H-RS and L&H cells. We also discuss major cellular and molecular mediators contributing to the establishment and maintenance of a reactive background in HL-affected tissues. We believe that an in-depth understanding of the pathogenesis of HL will eventually lead to the development of novel biologically based therapeutic strategies in the near future. PMID:16155023

    Despite its well-known histological and clinical features, Hodgkin's lymphoma (HL) has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics, histogenesis, and possible mechanisms of lymphomagenesis. There is complete consensus on the B-cell derivation of the tumor in most cases, and on the relevance of Epstein-Barr virus infection and defective cytokinesis in at least a proportion of patients. The REAL/WHO classification recognizes a basic distinction between lymphocyte predominance HL (LP-HL) and classic HL (cHL), reflecting the differences in clinical presentation and behavior, morphology, phenotype, and molecular features. cHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, with mixed cellularity, and lymphocyte depleted. The borders between cHL and anaplastic large-cell lymphoma have become sharper, whereas those between LP-HL and T-cell-rich B-cell lymphoma remain ill defined. Treatments adjusted to the pathobiological characteristics of the tumor in at-risk patients have been proposed and are on the way to being applied. PMID:21253495

Higher-grade non-Hodgkin lymphoma (NHL) and therapy-related myelodysplasia/acute leukemia (t-MDS/AML) have been reported in patients with WM/LPL in previous studies. However, only two cases with WM/LPL were reported to develop to Hodgkin lymphoma (HL). Here, we report the first case of WM/LPL who developed classical HL simultaneously 3 years after initial nucleoside analog-based chemotherapy. PMID:26273017

    A unique feature of the germinal center B cell-derived Hodgkin and Reed/Sternberg cells of classical Hodgkin lymphoma is their lost B cell phenotype and the aberrant expression of factors of other hematopoietic cell types, including ID2 and NOTCH1. As cellular dedifferentiation and upregulation of ID2 and NOTCH1 are typical consequences of a hypoxic response, we wondered whether hypoxia may impose an HRS cell-like phenotype in B cells. Culturing normal B cells or cell lines of germinal center-type diffuse large B-cell lymphoma under hypoxic conditions caused partial downregulation of several B cell markers, ID2 upregulation, and increased NOTCH1 activity. The hypoxic cells acquired further features of Hodgkin and Reed/Sternberg cells, including increased JUN expression, and enhanced NF?B activity. The Hodgkin and Reed/Sternberg cell-expressed epigenetic regulators KDM4C and PCGF2, as well as the phosphatase DUSP1 were partially induced in hypoxic B cells. Inhibition of DUSP1 was toxic for classical Hodgkin lymphoma cell lines. Thus, hypoxia induces key Hodgkin and Reed/Sternberg cell characteristics in mature B cells. We speculate that hypoxic conditions in the germinal center may impose phenotypic changes in germinal center B cells, promoting their survival and initiating their differentiation towards a Hodgkin and Reed/Sternberg cell-like phenotype. These may then be stabilized by transforming events in the Hodgkin and Reed/Sternberg precursor cells. PMID:26160878

    2000-04-01

    Thomas Hodgkin's discovery of a lymph gland disorder is merely one event in a life of unusually varied public activities in the social reform and humanitarian movements of the mid-19th century. He wrote pamphlets on medical care for the working-class poor, public health, housing, sanitation, and the relief of cold, hunger, and unemployment. Hodgkin wrote about the problems arising from urban renewal and suburban development. His contributions to geographic explorations, anthropology, ethnology, and foreign affairs are virtually unknown today. Hodgkin's opposition to slavery and the slave trade involved him in the development of settlements in Africa for freed slaves and disputes with the abolitionists in America. He fought for social justice and human rights for native populations being oppressed by British foreign policy in South Africa and New Zealand. His criticism of the exploitation of Indians by the Hudson's Bay Company's fur trade contributed to a professional conflict in the highly politicized environment of Guy's Hospital and blocked advancement of his medical career. Closer to home he advocated reform of medical education and practice and sponsored adult education programs. As a member of its Senate, he helped in establishing London University, the first nonsectarian institution of higher learning in England. He lectured to working people on the means of preserving and promoting health and advocated prepaid medical care for the working poor. Concerned about unequal distribution of medical care, he opposed medical contracts to the lowest bidder and price-determined government plans for health care. He consistently maintained that the basic problems of the poor were not medical but socioeconomic. Since charity leaves nothing behind in exchange, Hodgkin was certain that greater benefits would result if charitable money was used to provide jobs. He denounced the evils of tobacco, practices of trade unions, and barbarous prize fights. On a trip to Jerusalem with Sir Moses Montefiore in 1866, Hodgkin contracted dysentery and died. He is buried in a protestant cemetery in Jaffa. His epitaph is fitting: "Nothing human was alien to him." PMID:10760325

    Knowledge Discovery in Databases is gaining attention and raising new hopes for traditional Chinese medicine (TCM) researchers. It is a useful tool in understanding and deciphering TCM theories. Aiming for a better understanding of Chinese herbal property theory (CHPT), this paper performed an improved association rule learning to analyze semistructured text in the book entitled Shennong's Classic of Materia Medica. The text was firstly annotated and transformed to well-structured multidimensional data. Subsequently, an Apriori algorithm was employed for producing association rules after the sensitivity analysis of parameters. From the confirmed 120 resulting rules that described the intrinsic relationships between herbal property (qi, flavor and their combinations) and herbal efficacy, two novel fundamental principles underlying CHPT were acquired and further elucidated: (1) the many-to-one mapping of herbal efficacy to herbal property; (2) the nonrandom overlap between the related efficacy of qi and flavor. This work provided an innovative knowledge about CHPT, which would be helpful for its modern research. PMID:24063783

    Despite its well known histological and clinical features, Hodgkin's lymphoma (HL) has recently been the object of intense research activity, leading to a better understanding of its phenotype, molecular characteristics, histogenesis, and possible mechanisms of lymphomagenesis. There is complete consensus on the B cell derivation of the tumour in most cases, and on the relevance of Epstein-Barr virus infection and defective cytokinesis in at least a proportion of patients. The REAL/WHO classification recognises a basic distinction between lymphocyte predominance HL (LP-HL) and classic HL (CHL), reflecting the differences in clinical presentation and behaviour, morphology, phenotype, and molecular features. CHL has been classified into four subtypes: lymphocyte rich, nodular sclerosing, with mixed cellularity, and lymphocyte depleted. The borders between CHL and anaplastic large cell lymphoma have become sharper, whereas those between LP-HL and T cell rich B cell lymphoma remain ill defined. Treatments adjusted to the pathobiological characteristics of the tumour in at risk patients have been proposed and are on the way to being applied. PMID:11896065

    Despite advances in immunohistochemistry and molecular biology, the distinction between classical Hodgkin's lymphoma and related diseases such as nodular lymphocyte-predominant Hodgkin's disease, T-cell rich large B-cell lymphoma or anaplastic large cell lymphoma has remained difficult in rare cases. Lack of clear-cut diagnostic criteria represents a problem for both the pathologist and the clinician. To delineate this 'grey zone' between classical Hodgkin's lymphoma and non-Hodgkin's lymphoma (NHL) and to develop criteria for classification of such cases, 12 expert hematopathologists each submitted one to five borderline cases to a workshop. Cases were reviewed and classified at a multiheaded microscope and criteria were established for the diagnosis of questionable cases. Well established entities such as classical Hodgkin's lymphoma, anaplastic large-cell lymphoma and TCRBCL were defined more strictly and cases with unusual morphology or antigen expression could be identified. A distinctive subset of cases representing mediastinal large B-cell lymphomas with features of Hodgkin's lymphoma was identified. PMID:9926235

    Alopecia areata (AA) has been classically associated with several autoimmune disorders. However, AA as a paraneoplastic syndrome of Hodgkin’s lymphoma (HL) remains a rare entity and our understanding of this phenomenon is limited to a few case reports. This is the case report of a 46-year-old male patient who was diagnosed with AA several months prior to the onset of B symptoms and the diagnosis of stage IVB classical HL. The patient was subsequently treated with 6 cycles of adriamycin, bleomycin, vinblastine and dacarbazine and experienced a complete response and resolution of his AA. In our case, the onset of AA preceded the onset of systemic manifestations and diagnosis of HL, whereas in other cases AA was shown to occur concurrently with the clinical manifestations of HL. In all the cases, however, treatment of the HL subsequently led to resolution of the AA. The present case report highlights the significance of AA as a herald of underlying malignancy, although AA in classical HL remains poorly characterized in the literature. PMID:24940502

    Hodgkin lymphoma (HL) is one of the most curable pediatric and adult cancers, with long-term survival rates now exceeding 90% after treatment with chemotherapy alone or combined with radiotherapy (RT). Of note, global collaboration in clinical trials within cooperative pediatric HL study groups has resulted in continued progress; however, survivors of pediatric HL are at high risk of potentially life-limiting second cancers and treatment-associated cardiovascular disease. Over the last three decades, all major pediatric and several adult HL study groups have followed the paradigm of response-based treatment adaptation and toxicity sparing through the reduction or elimination of RT and tailoring of chemotherapy. High treatment efficacy is achieved using dose-dense chemotherapy. Refinement and reduction of RT have been implemented on the basis of results from collaborative group studies, such that radiation has been completely eliminated for certain subgroups of patients. Because pediatric staging and response criteria are not uniform, comparing the results of trial series among different pediatric and adult study groups remains difficult; thus, initiatives to harmonize criteria are desperately needed. A dynamic harmonization process is of utmost importance to standardize therapeutic risk stratification and response definitions as well as improve the care of children with HL in resource-restricted environments.

    Curcumin, a phytochemical isolated from curcuma plants which are used as coloring ingredient for the preparation of curry powder, has several activities which suggest that it might be an interesting drug for the treatment or prevention of cancer. Curcumin targets different pathways which are involved in the malignant phenotype of tumor cells, including the nuclear factor kappa B (NFKB) pathway. This pathway is deregulated in multiple tumor entities, including Hodgkin’s lymphoma (HL). Indeed, curcumin can inhibit growth of HL cell lines and increases the sensitivity of these cells for cisplatin. In this review we summarize curcumin activities with special focus on possible activities against HL cells. PMID:24665206

    Background: Hodgkin’s lymphoma (HL) is a B cell lymphoma characterized by the presence of Reed-Sternberg cells. HL comprises 1% of all cancer cases and 14% of all lymphoma cases. Aims: We designed a retrospective study to investigate the clinical features and prognostic factors of HL patients diagnosed at an experienced oncology centre. Study Design: Retrospective study. Methods: Demographic characteristics, histopathological and clinical features, treatment modalities and response to treatment were obtained from hospital records. Dates of initial diagnosis, remission and relapse, last visit and death were recorded for survival analyses. Results: We analysed data of 391 HL patients (61% male, 39% female; mean age 35.7±15.1 years). The most common classical HL histological subtype was nodular sclerosing HL (NSHL) (42.7%). The most common stage was II 50.4%. The most common chemotherapy regimen was doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) (70.6%). Five and 10-year survival rates were 90% and 84%, respectively. Early-stage patients with good prognostic factors had better overall and relapse-free survival rates. The presence of “B” symptoms, albumin level, Eastern Cooperative Oncology Group (ECOG) performance score, and LDH were prognostic factors that affect the survival in both univariate and multivariate analyses. Conclusion: This is the first study that demonstrates the demographic, clinical and prognostic features of HL patients in Turkey, and provides a general picture of the HL patients in our country.

    The authors report 3 cases of Hodgkin's disease with intracranial involvement. The patients were 4, 12, and 15 years old (male/female=1/2). Initially, they were treated with ABVD or COPP chemotherapies and low-dose involved field radiotherapy. Intracranial recurrences occurred 27, 40, and 42 months after initial diagnosis, respectively. Two patients experienced convulsions and the other complained of diplopia. The metastatic lesions were located supratentorially with CT or MRI. Despite initial response achieved following systemic chemotherapy and external irradiation to cranial lesions, all patients died with disseminated disease. In patients with intracranial involvement of Hodgkin's disease, prolonged disease-free survival may be achieved by combined modality treatment. PMID:16166052

  13. EXPONENTIAL TIME DIFFERENCING FOR HODGKIN-HUXLEY-LIKE ODES.

    PubMed

    Börgers, Christoph; Nectow, Alexander R

    2013-01-01

    Several authors have proposed the use of exponential time differencing (ETD) for Hodgkin-Huxley-like partial and ordinary differential equations (PDEs and ODEs). For Hodgkin-Huxley-like PDEs, ETD is attractive because it can deal effectively with the stiffness issues that diffusion gives rise to. However, large neuronal networks are often simulated assuming "space-clamped" neurons, i.e., using the Hodgkin-Huxley ODEs, in which there are no diffusion terms. Our goal is to clarify whether ETD is a good idea even in that case. We present a numerical comparison of first- and second-order ETD with standard explicit time-stepping schemes (Euler's method, the midpoint method, and the classical fourth-order Runge-Kutta method). We find that in the standard schemes, the stable computation of the very rapid rising phase of the action potential often forces time steps of a small fraction of a millisecond. This can result in an expensive calculation yielding greater overall accuracy than needed. Although it is tempting at first to try to address this issue with adaptive or fully implicit time-stepping, we argue that neither is effective here. The main advantage of ETD for Hodgkin-Huxley-like systems of ODEs is that it allows underresolution of the rising phase of the action potential without causing instability, using time steps on the order of one millisecond. When high quantitative accuracy is not necessary and perhaps, because of modeling inaccuracies, not even useful, ETD allows much faster simulations than standard explicit time-stepping schemes. The second-order ETD scheme is found to be substantially more accurate than the first-order one even for large values of ?t. PMID:24058276

    2008-01-01

    Background CD30, a 120 kDa surface phosphorylated protein is a member of tumour necrosis/nerve growth factor receptor (TNF/NGFR) family and constitutively expressed by Hodgkin and Reed-Sternberg (HRS) cells of Hodgkin lymphoma (HL) and the neoplastic cells of Anaplastic Large Cell Lymphoma (ALCL). A disease-specific protein marker is yet to be identified in Hodgkin lymphoma cells. In order to define HL-specific biomarkers, novel murine monoclonal antibodies were developed in our laboratory. Results Murine monoclonal antibodies (mabs) were raised against the B3 sub clone of HL-derived cell line KM-H2. Two of these mabs (clone R23.1 mab and clone R24.1 mab) are IgG1 class antibodies that recognize a 21 kDa protein present at the cell membrane and in the cytoplasm in HL-derived cell lines. Clone R24.1 mab recognizes a formalin-resistant epitope and labels HRS cells in tissue samples from patients with HL of the classical type, ALCL, and subsets of T and B cell aggressive Non-Hodgkin Lymphomas (NHL). The antigen recognized by the clone R23.1 mab and clone R24.1 mab does not share epitopes with CD30 cluster regions A, B, or C, and, unlike CD30, is not expressed by phytohemagglutinin (PHA) activated T cells. Conclusion The 21 kDa protein detected by clone R23.1 and clone R24.1 mabs is a novel membrane-associated protein that may be a potential marker for the diagnosis and targeted therapy of HL and aggressive T and B cell NHL.

    2007-10-01

    The authors report a peculiar form of Hodgkin's disease that is associated with Epstein-Barr virus infection. A 16-year-old patient was admitted for an autoimmune haemolytic anaemia associated with IgG auto-immune antibodies, linked to general clinical complications, cervical adenopathies and splenomegalia. The patient underwent hemicavectomy that was not histologically investigated. The ganglionar exeresis helped to establish the histological diagnosis of Hodgkin's disease, classic form with nodular sclerosis. Tumour cells were CD30 CD15 positive and neighbouring lymphoid cells were CD3 and CD20 positive. In situ hybridation allowed the detection of Epstein-Barr virus in tumour cells. Under ABVD chemotherapy supplemented with acyclovir and initial corticotherapy, mid-treatment evolution appears to be favourable. This observation is consistent with the hypothesis that tumour cells are of B cell origin during Hodgkin's disease, together with the involvement of Epstein-Barr virus in lymphomagenesis.

    The growth fraction of tumor cells was studied in 45 cases of Hodgkin's disease by means of a recently developed double immunostaining technique using monoclonal antibody Ki-1, which reacts selectively with Hodgkin and Reed-Sternberg cells in tissues affected by Hodgkin's disease, and antibody Ki-67, which recognizes a cell proliferation-associated nuclear antigen. The medians of the growth fractions of the tumor cells in all histologic subtypes of Hodgkin's disease varied between 78% and 83%. In none of the cases investigated did we find a growth fraction below 50%. Furthermore, mononucleated Hodgkin cells as well as multi-nucleated Reed-Sternberg cells showed a similar Ki-67 labeling index, indicating that both tumor cell types belong to the proliferating pool of this malignancy.

    The creation of a complex telemedical system oriented towards childhood Hodgkin's disease has been undertaken at the Department of Bioinformatics and Telemedicine of the Jagiellonian University Medical College in cooperation with the Department of Oncology and Pediatric Hematology of the Polish-American Institute of Pediatrics, JU MC. Data collecting, data processing and data transmission is aimed to aid and/or supervise surgical and drug treatment. The Tele-Database of Childhood Hodgkin's Disease (TDCHD) is not a simple Internet database project. A few hundred data items are presented in each patient's record, covering the complete medical treatment period. Efficient management and proper data protection are necessary for a medical database. Therefore, the interface for entering data has been divided into several parts. Each part is subjected to separate editing and transfer. A double-layer debugging system has been applied in the program: the first pass occurs on the client side (programmed in JavaScript and XML), the second - on the server side (programmed in PHP). Strict authorization is requested for all participants. Clinical data collected according to management standards and information governance (data quality, security and confidentiality) is organized in a way that facilitates practical and scientific use.

    Because nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) express CD20, rituximab may be used as a nonmutagenic treatment option to avoid late toxicities in this rather indolent entity. Between 1999 and 2004, the German Hodgkin Study Group (GHSG) investigated the activity of rituximab (375 mg/m(2) in 4 doses) in a phase 2 trial in 21 relapsed or refractory NLPHL patients. The initial diagnosis of NLPHL was confirmed in 15 of the 21 enrolled patients by reference pathology. The remaining cases were reclassified as Hodgkin lymphoma transformed to T-cell rich B-cell lymphoma (TCRBCL; n = 2) or CD20(+) classical Hodgkin lymphoma (cHL; n = 4). In NLPHL patients the overall response rate was 94%, including 8 complete remission (CR) and 6 partial remission (PR). With a median follow-up of 63 months (range, 3-84), the median time to progression was 33 months, with the median overall survival (OS) not reached. Thus, rituximab is highly effective in relapsed and refractory NLPHL. This study is registered at http://www.klinisches-studienzentrum.de/trial/285. PMID:17938252

    Nodular lymphocyte predominant Hodgkin lymphoma represents a distinct entity from classical Hodgkin lymphoma. We conducted a retrospective study to investigate the management of patients with nodular lymphocyte predominant Hodgkin lymphoma. Clinical characteristics, treatment and outcome of adult patients with nodular lymphocyte predominant Hodgkin lymphoma were collected in Lymphoma Study Association centers. Progression-free survival (PFS) and overall survival (OS) were analyzed, and the competing risks formulation of a Cox regression model was used to control the effect of risk factors on relapse or death as competing events. Among 314 evaluable patients, 82.5% had early stage nodular lymphocyte predominant Hodgkin lymphoma. Initial management consisted in watchful waiting (36.3%), radiotherapy (20.1%), rituximab (8.9%), chemotherapy or immuno-chemotherapy (21.7%), combined modality treatment (12.7%), or radiotherapy plus rituximab (0.3%). With a median follow-up of 55.8 months, the 10-year PFS and OS estimates were 44.2% and 94.9%, respectively. The 4-year PFS estimates were 79.6% after radiotherapy, 77.0% after rituximab alone, 78.8% after chemotherapy or immuno-chemotherapy, and 93.9% after combined modality treatment. For the whole population, early treatment with chemotherapy or radiotherapy, but not rituximab alone (Hazard ratio 0.695 [0.320–1.512], P=0.3593) significantly reduced the risk of progression compared to watchful waiting (HR 0.388 [0.234–0.643], P=0.0002). Early treatment appears more beneficial compared to watchful waiting in terms of progression-free survival, but has no impact on overall survival. Radiotherapy in selected early stage nodular lymphocyte predominant Hodgkin lymphoma, and combined modality treatment, chemotherapy or immuno-chemotherapy for other patients, are the main options to treat adult patients with a curative intent.

    Introduction. Hodgkin lymphoma shows a well-known geographic pattern, but temporal changes have been found recently as well. Patients and Methods. 439 Hodgkin lymphoma patients' clinicopathological and treatment data were processed in calendar periods of approximately ten years. The patients were treated at our department from 1980 until the end of 2008. Results. The first period (1980–89) contained 177 patients, the second (1990–99) 147, and the third (2000–08) 115 Hodgkin lymphoma patients. The mean age of the patients was 40.1, 35.9, and 36.8 years in order. The male/female ratio: 1.42, 1.45, 1.05 in order. Contrary-wise a unimodal age group pattern could have been seen with an incidence peak between 30 and 39 in the past decades. The incidence of classical mixed cellularity histological subtype is decreasing (43.7%, 58.23%, 42.6%, P = 0.0098 (it is only significant in the second period)); classical nodular sclerosis shows an increasing tendency (25%, 27.32%, 34.78%, P = 0.1734). The first incidence peak is predominantly created by classical nodular sclerosis, meanwhile the second peak by classical mixed cellularity. The number of early-stage patients (59.12%) is beyond the advanced stage (40%) in the last decade. Meanwhile, the number of second-stage patients was increasing (25.8%, 26.35%, 49.56%??P < 0.0001) and of patients in third stage was decreasing (53.4 %, 50.67%, 20%??P < 0.0001). The 5- and 10-year overall survival data were progressing: 59.7 %, 77.4 %, and 90.5 % and 44.1 %, 70.6 % and 90.5 % (expected survival) in the last decade. Conclusions. Changes can be explained by the altered nature of Hodgkin lymphoma, the changes in socioeconomic status and the development of diagnostic and therapy methods. PMID:22195285

    From a pedagogical point of view, the memristor is defined in this tutorial as any 2-terminal device obeying a state-dependent Ohm’s law. This tutorial also shows that from an experimental point of view, the memristor can be defined as any 2-terminal device that exhibits the fingerprints of ‘pinched’ hysteresis loops in the v-i plane. It also shows that memristors endowed with a continuum of equilibrium states can be used as non-volatile analog memories. This tutorial shows that memristors span a much broader vista of complex phenomena and potential applications in many fields, including neurobiology. In particular, this tutorial presents toy memristors that can mimic the classic habituation and LTP learning phenomena. It also shows that sodium and potassium ion-channel memristors are the key to generating the action potential in the Hodgkin-Huxley equations, and that they are the key to resolving several unresolved anomalies associated with the Hodgkin-Huxley equations. This tutorial ends with an amazing new result derived from the new principle of local activity, which uncovers a minuscule life-enabling ‘Goldilocks zone’, dubbed the edge of chaos, where complex phenomena, including creativity and intelligence, may emerge. From an information processing perspective, this tutorial shows that synapses are locally-passive memristors, and that neurons are made of locally-active memristors.

    Classical Hodgkin lymphoma (cHL) is a malignancy with complex pathogenesis. The hallmark of the disease is the presence of large mononucleated Hodgkin and bi- or multinucleated Reed/Sternberg (H/RS) cells. The origin of HRS cells in cHL is controversial as these cells show the coexpression of markers of several lineages. Using a proteomic approach, we compared the protein expression profile of cHL models of T- and B-cell derivation to find proteins differentially expressed in these cell lines. A total of 67 proteins were found differentially expressed between the two cell lines including metabolic proteins and proteins involved in the regulation of the cytoskeleton and/or cell migration, which were further validated by western blotting. Additionally, the expression of selected B- and T-cell antigens was also assessed by flow cytometry to reveal significant differences in the expression of different surface markers. Bioinformatics analysis was then applied to our dataset to find enriched pathways and networks, and to identify possible key regulators. In the present study, a proteomic approach was used to compare the protein expression profiles of two cHL cell lines. The identified proteins and/or networks, many of which not previously related to cHL, may be important to better define the pathogenesis of the disease, to identify novel diagnostic markers, and to design new therapeutic strategies.

    Meridian theory is one of the core components of the theory of traditional Chinese medicine (TCM). It gives an integral explanation for how human life works, how a disease forms, and how a therapy acts to treat a disease. If we do not understand the meridians, it is hard to understand the TCM. People in China and abroad had been working hard for 50 years, trying to understand the meridians; then 15 years ago a breakthrough idea appeared when we realized that they are low resistance fluid channels where various chemical and physical transports take place. The channel is called low hydraulic resistance channel (LHRC) and the chemical transport is named volume transmission (VT). This review aims to give a full understanding of the essence of meridian and its works on the therapies of TCM. PMID:25821487

    Hodgkin's lymphoma is characterized by the combination of Reed-Sternberg (R-S) cells and a prominent inflammatory cell infiltrate. One of the intriguing questions regarding this disease is what is causing the influx of T lymphocytes into the involved tissues. We applied the serial analysis of gene expression (SAGE) technique on the Hodgkin's lymphoma-derived cell line L428 and on an Epstein-Barr virus (EBV)-transformed lymphoblastoid B-cell line. A frequently expressed tag in L428 corresponded to the T-cell-directed CC chemokine TARC. Reverse transcription polymerase chain reaction analyses demonstrated expression of TARC in nodular sclerosis (NS) and mixed cellularity (MC) classical Hodgkin's lymphomas but not in NLP Hodgkin's lymphoma, anaplastic large-cell lymphomas, and large-B-cell lymphomas with CD30 positivity. Two of five cases of T-cell-rich B-cell lymphoma (TCRBCL) were TARC positive. RNA in situ hybridization (ISH) showed a strong signal for TARC in the cytoplasm of R-S cells, and immunohistochemical staining confirmed the presence of the TARC protein in the R-S cells of NS and MC Hodgkin's lymphomas. The lymphocytic and histiocytic (L&H)-type cells of nodular lymphocyte predominance Hodgkin's lymphoma and the neoplastic cells of non-Hodgkin's lymphomas with the exception of two cases of TCRBCL did not stain for TARC. TARC is known to bind to the CCR4 receptor, which is expressed on activated Th2 lymphocytes. The immunophenotype of lymphocytes surrounding R-S cells is indeed Th2-like, and by RNA ISH these lymphocytes showed a positive signal for the chemokine receptor CCR4. The findings suggest that production of TARC by the R-S cells may explain the characteristic T-cell infiltrate in classical Hodgkin's lymphoma. PMID:10362793

    In France, adolescents (15-20 years) with non Hodgkin's lymphoma (NHL) are referred either to paediatric or to adult onco-haematological departments. According to data obtained from regional tumour registries (covering about 10% of France), their 5 year survival rate was 59% whereas it was 87% for children (< or =14 years) treated for NHL during a similar period of time. We reviewed the management of NHL either by the paediatricians or the onco-hematologists for adults. The categories of NHL that are reviewed and whose clinical and biological characteristics are presented are: Burkitt, lymphoblastic and large cell, either B or anaplastic. This review shows that, in most series, outcome was better in children than in adults. This raises the reasons of this difference: is it due to the different therapeutic approaches, to different tolerance of chemotherapy, to different biology within the same histological type ? Further studies specific to the adolescents are needed to better know the biology of their lymphoma and to determine the best therapeutic approach. PMID:17449436

    In the past several decades, Hodgkin's disease has been transformed from a uniformly fatal illness to one that can be treated with the expectation of long-term remission or cure in the majority of patients. Because patients now survive for long periods after curative intervention, various complications have been identified. The spectrum of complications following curative therapy is quite diverse and includes immunologic, cardiovascular, pulmonary, thyroid, and gonadal dysfunction. In addition, second malignant neoplasms in the form of acute leukemia as well as secondary solid tumors have now been documented to occur with increased frequency in patients cured of Hodgkin's disease. 80 references.

    2015-01-01

    There has been a recent emergence of novel targeted agents for treatment of Hodgkin and non-Hodgkin lymphoma. In particular, antibodies and antibody-drug conjugates directed against surface antigens, agents that block immune checkpoint pathways, and small molecule inhibitors directed against cell signaling pathways have shown significant promise in patients with relapsed and refractory disease and in the frontline setting. With the development of these new therapies, cytotoxic chemotherapy may be avoided entirely in some clinical settings. This review will present the latest information on these novel treatments in Hodgkin and non-Hodgkin lymphoma and will discuss both recently approved agents as well as drugs currently being studied in clinical trials.

    Classical swine fever (CSF), or hog cholera, is a highly contagious disease that emerged in the first half of the nineteenth century. To fight against the disease and protect pigs, different vaccines were developed, including early generation of lapinized Rovac strain and the later development of the “Chinese” strain (C-strain). However, details of the development of these vaccines are lost in history. In order to investigate the phylogenetic relationship between the Rovac and other lapinized vaccines, this study determined the genome sequence of the Rovac, which comprised 12,304 nucleotides, notably with the 3?untranslated region (3?UTR) containing a 13-nucleotide insertion. The near-complete genome of Russian vaccine strain LK-VNIVViM was determined by next-generation sequencing on Illumina MiSeq platform. Whole genome phylogenetic analysis revealed a closer relationship of the Rovac strain with the Russian LK-VNIVViM, CS strain and its derivative RUCSFPLUM (genotype 1.2), rather than with the C-strain (genotype 1.1). In addition, it demonstrated an ancestry role of the LK-VNIVViM in relation to the CS strain and RUCSFPLUM. The study suggested that the Rovac vaccine is the possible ancestor of the Russian vaccine strains but not the C-strain vaccine. PMID:25306909

    Thirty-four patients with Hodgkin's disease and non-Hodgkin's lymphoma underwent therapeutic splenectomies to improve hematologic tolerance for chemotherapy. The mean age was 40 years; there were 16 males and 18 females. Fourteen had Hodgkin's disease, 19 had non-Hodgkin's lymphoma, and 1 had malignant histocytosis. Nineteen had palpable splenomegaly, 19 had marrow involvement and 20 had splenic involvement by lymphoma. The following data were analyzed before and after splenectomy: mean white blood cell count (WBC) and platelet count on planned first day of cycle, delay ratio of chemotherapy delivery and percent maximal dose rate. Thirteen patients had non-Hodgkin's lymphoma, splenomegaly and positive bone marrow and showed significant benefit in all of the aforementioned parameters. Of the patients with prior irradiation, only those who completed their radiation greater than six months prior to splenectomy showed benefit. Ten patients had Hodgkin's disease, negative bone marrow and no splenomegaly. This group showed significant improvement in mean platelet count but more limited benefit in delay ratio and percent maximal dose rate. Thus, selected patients with lymphoma who are experiencing delays in chemotherapy because of poor count tolerance may benefit from splenectomy.

    Induction of genetic damage in germ cells of young patients receiving chemo- or radiotherapy for cancers with probable cure, such as Hodgkin`s disease, is cause for concern. These young patients may someday desire children, and germ cell alterations presenting as numerical chromosomal abnormalities in sperm may place their future offspring at risk. To address this concern, we measured aneuploidy in sperm from eight young Hodgkin`s disease patients: four pre-treatment, four during treatment, and three over a 45 month period following treatment with NOVP (Novantrone, Oncovin, Vinblastine and Prednisone). Patients ranged in stage of disease from IA-IIEB and none had received prior radiation or chemotherapy. Using multi-chromosome sperm FISH with repetitive sequence probes specific for chromosomes X, Y and 8, we found a significant 2-4 fold increase in particular numerical chromosomal abnormalities during treatment which were limited in persistence post-treatment. Additionally, pre-treatment Hodgkin`s disease patients showed elevations in some numerical chromosomal abnormalities when compared to a healthy reference group. In several men, the fraction of aneuploid sperm did not return to healthy reference group levels even after completion of therapy. These results show that elevated sperm aneuploidy occurs in germ cells of young cancer patients during chemotherapy and suggest caution to prevent conceptions during this period. The elevated sperm aneuploidy appears transient, but in some cases never returns to healthy reference group levels.

    Pixantrone (BBR-2778) is a novel aza-anthracenedione anthracycline derivative developed by Cell Therapeutics Incorporated, WA, USA. Pixantrone is similar in structure to the anthracenedione mitoxantrone but lacks the 5, 8-dihydroxy substitution groups implicated in mitoxantrone-induced cardiotoxicity. The PIX301 phase III single-agent trial of pixantrone for patients with relapsed or refractory aggressive non-Hodgkin's lymphoma randomized patients to receive either pixantrone or another single agent of the investigators' choice. The rate of confirmed and unconfirmed remissions in patients treated with pixantrone was significantly higher than in those receiving other agents, as was the overall response rate and progression-free survival. There is evidence that pixantrone is well tolerated when substituted for anthracyclines in combination regimens for aggressive non-Hodgkin's lymphoma with comparable rates of complete remission. Pixantrone has also been used for the treatment of indolent non-Hodgkin's lymphomas and the combination of pixantrone and rituximab has been shown to be superior to rituximab alone in relapsed or refractory disease in the phase III PIX302 study. On the basis of these data, the United States Food and Drug Administration is considering pixantrone for use in adult patients with relapsed or refractory aggressive and indolent non-Hodgkin's lymphoma on a fast-track basis.

    Porcine reproductive and respiratory syndrome (PRRS) is a leading disease in pig industry worldwide and can result in serious economic losses each year. The PRRS epidemic situation in China has been very complicated since the unprecedented large-scale highly pathogenic PRRS (HP-PRRS) outbreaks in 2006. And now the HP-PRRS virus (HP-PRRSV) and classical North American type PRRSV strains have coexisted in China. Rapid differential detection of the two strains of PRRSV is very important for effective PRRS control. The real-time RT-PCR for simultaneous detection and differentiation of HP-PRRSV and PRRSV by using both SYBR Green and TaqMan probes was developed and validated. Both assays can be used for rapid detection and strain-specific identification of HP-PRRSV and PRRSV. However, the TaqMan probe method had the highest detection rate whereas the conventional RT-PCR was the lowest. The real-time RT-PCR developed based on SYBR Green and TaqMan probe could be used for simultaneous detection and differentiation of HP-PRRSV and PRRSV in China, which will benefit much the PRRS control and research.

    Multinucleated Reed–Sternberg (RS) cells are pathognomonic for classical Hodgkin lymphoma (HL), and their presence is essential for diagnosis. How these giant tumor cells develop is controversial, however. It has been postulated that RS cells arise from mononucleated Hodgkin cells via endomitosis. Conversely, continuous single-cell tracking of HL cell lines by long-term time-lapse microscopy has identified cell fusion as the main route of RS cell formation. In contrast to growth-induced formation of giant Hodgkin cells, fusion of small mononuclear cells followed by a size increase gives rise to giant RS cells. Of note, fusion of cells originating from the same ancestor, termed re-fusion, is seen nearly exclusively. In the majority of cases, re-fusion of daughter cells is preceded by incomplete cytokinesis, as demonstrated by microtubule bonds among the cells. We confirm at the level of individual tracked cells that giant Hodgkin and RS cells have little proliferative capacity, further supporting small mononuclear Hodgkin cells as the proliferative compartment of the HL tumor clone. In addition, sister cells show a shared propensity for re-fusion, providing evidence of early RS cell fate commitment. Thus, RS cell generation is related neither to cell fusion of unrelated Hodgkin cells nor to endomitosis, but rather is mediated by re-fusion of daughter cells that underwent mitosis. This surprising finding supports the existence of a unique mechanism for the generation of multinuclear RS cells that may have implications beyond HL, given that RS-like cells are frequently observed in several other lymphoproliferative diseases as well.

    A case-control study was conducted to assess the effect of occupational exposures on the risk of non-Hodgkin's lymphoma. Interviews were conducted with 303 persons with non-Hodgkin's lymphoma newly diagnosed from January 1, 1980, to May 31, 1982, among residents of the Boston, MA, metropolitan area and 303 age and gender matched controls. The study found an increased risk of disease among persons employed in the agriculture, forestry, and fishing industry [relative risk (RR) = 3.0]; the construction industry [RR = 2.1]; and the leather industry [RR = 2.1]. The particular job groupings at increased risk were plant farmers and gardeners (RR unbounded); painters and plasterers (RR = 6.0); and carpenters, brick and stone masons, plumbers, and roofers (RR = 12.0). Although other exposures may have led to these increased risks, the findings in this study are consistent with an increased risk of non-Hodgkin's lymphoma for workers who may be exposed to chlorophenols or phenoxyacetic acids.

    Introduction. The aim of this retrospective, unicentric study over 5 years is to describe the epidemiologic, pathologic, clinic and therapeutic aspects of children treated for Hodgkin lymphoma in our paediatric oncology unit. Patients and Methods. From January 2005 to December 2009, all children under 18 years of age, with Hodgkin lymphoma were included in this study. The treatment protocol was the GFAOP (Groupe Franco—Africain d'Oncologie Pédiatrique) Hodgkin lymphoma treatment protocol. Results. During the study period, 217 cancer cases were diagnosed in our centre. Of these cases, 7 were Hodgkin Lymphoma (LH) (0.04%). The mean age was 11.7 years. The sex-ratio was 6/1. 4% (5/7) of patients were stage IIB and 28.6% (2/7) stage IIIB of Ann-Arbor classification. There were 3 cases (42.8%) of sclero-nodular subtype, 2 cases (28.6%) of lymphocyte-rich classical HL subtype, 1 case (14.3%) of mixed cellularity and 1 case (14.3%) of lymphocyte depleted subtype. With a median followup of 37 months, 5 patients (71.4%) are alive, and 2 patients (28.6%) died. Conclusion. Broader multicentric studies are needed for more accurate data on this malignancy.

    Lymphomas are malignant neoplasms arising from lymphocytes B cell or T cell that affects mainly lymph nodes, spleen and other non hematopoietic tissues. They are classified as Hodgkin’s lymphoma (HL) and non-Hodgkin’s lymphoma (NHL). Diffuse large B-cell lymphoma (DLBL) is the most common variant of non-Hodgkin’s lymphomas and frequently involves extranodal sites. In the oral soft tissues lesions can occur as hard and diffuse tumors involving oral vestibule, gums and posterior region of the hard palate. Most lymphomas, including DLBL arise from B cells are characterized by diffuse population of large cells with cleaved or non cleaved oval nuclei. Both histopathlogical and immunohistochemical (IHC) analysis were strongly advisable for proper management and prognosis. We hereby report a rare case of Diffuse large B-cell variant of non-Hodgkin’s lymphoma in a male patient of age 50yrs in left upper buccal vestibule. PMID:25302245

    Adrenal masses are described in seven cases of non-Hodgkin lymphoma in a series of 173 patients. In all seven patients the lymphoma was diffuse rather than nodular. Three patients had adrenal masses at the time of presentation, whereas in four cases the adrenal gland was a site of tumor recurrence after therapy. Three patients had simultaneous bilateral adrenal involvement by tumor. No characteristic features were recognized that might have distinguished these tumors from other adrenal masses. Appropriate therapy successfully resolved the adrenal masses in all but one case. The latter patient was the only one with evidence of adrenal insufficiency.

    2010-01-01

    Background A 24-year-old female patient was diagnosed with classic Hodgkin's lymphoma in clinical stage II, and combination chemotherapy followed by radiotherapy was initiated. During the following 5 years, the disease progressed despite several standard therapeutic approaches, including autologous and allogeneic stem cell transplantation. Methods Lenalidomide (25 mg daily) treatment was then initiated in a continuous dosing schedule. Positron emission tomography scans were performed before and during lenalidomide treatment. Hematologic and laboratory values, as well as physical condition were also assessed before and during lenalidomide treatment. Results Four months after continuous lenalidomide treatment, tumor load was significantly reduced, B symptoms had resolved, and the patient's physical condition had improved, allowing her to resume normal daily-living activities. Evaluations after 15 months of lenalidomide treatment indicated limited disease progression. Nevertheless, the patient was feeling well and maintaining a normal active life. Treatment was well tolerated, allowing the patient to remain on continuous dosing, which has now been maintained for 18 months. Conclusion Daily, long-term lenalidomide treatment provided clinical benefit and was well tolerated in a patient with relapsed, advanced classic Hodgkin's lymphoma. PMID:20509896

    2002-09-01

    Every patient in every part of the world has the right to expect the best possible quality of care from health care providers. Non-Hodgkin's lymphomas (NHL) are an extremely heterogeneous group of conditions which require important decisions to be taken at many points along the treatment pathway. To get this right every time requires that high-quality standards are instituted and adhered to, so that the best possible outcome is achieved. In the past this has not always been the case because of the failure of clinicians sometimes to adhere to an optimal management plan. In 1995, the UK government commissioned an inquiry into the running of cancer services in the United Kingdom, which culminated in a series of recommendations to improve them. Subsequently, these recommendations were implemented as objectives of the NHS Cancer Plan which is the framework by which the UK government wishes to improve cancer services. Concurrently another general concept has emerged which is designed to ensure that the highest quality standards may be achieved for all patients across the whole National Health Service (NHS). This concept, termed 'clinical governance', brings together a corporate responsibility of all health care workers to deliver high quality standards, in the hope that this will translate into better long-term survival of patients with malignant disease. This chapter focuses on the issues surrounding clinical governance and how the principles of this concept relate to non-Hodgkin's lymphomas. PMID:12468407

    We report on a patient with recurrent T-cell-rich B-cell lymphoma (TCRBCL), initially misdiagnosed as a lymphocyte-rich Hodgkin's disease. This case exemplifies the diagnostic problems of TCRBCL and the need for immunophenotypic analysis to differentiate TCRBCL from Hodgkin's disease, nodular paragranuloma and peripheral T-cell lymphoma. A rather unusual aspect is the long disease-free interval between the excision of the node in and the late relapse in 1996. The significance of the abundant T-cell infiltration in this B-cell neoplasm will be discussed and the concepts concerning antitumor response will be reviewed. Based on epidemiological data and the clinical behaviour TCRBCL does not seem to represent a distinctive pathological entity. PMID:10221522

    The incidence of non-Hodgkin's lymphomas continues to rise and the number of deaths attributable to these malignancies currently rank in the top five causes of cancer-related deaths in the United States. Recent insights into the pathogenesis and molecular characterization of these disorders have led to improvements in a clinicopathologically relevant classification system, as well as in the ability to accurately diagnose specific entities. Several new treatment modalities have been developed which may improve the outcome for selected patients. A better understanding of the biology of non-Hodgkin's lymphomas will hopefully translate into different therapies with improved outcomes. This article describes a new system for classifying the non-Hodgkin's lymphomas, highlights key aspects of the pathogenesis of non-Hodgkin's lymphomas and briefly reviews clinical and therapeutic approaches to the most common of these lymphomas.

    Systematic studies of the patterns of anatomic distribution, pathways of probable spread, and prognosis of the malignant lymphomas have been greatly aided by the development of new histopathologic classifications and the introduction of more sophisticated and precise diagnostic techniques, such as lymphangiography and laparotomy with splenectomy and retroperitoneal node biopsy. Concomitantly, megavoltage radiotherapy apparatus has made total-lymphoid radiotherapy feasible and practical, and the availability of a widening spectrum of chemotherapeutic agents has ushered in a new era of combination chemotherapy. Collectively, these diagnostic and therapeutic advances have already begun to yield a dramatic improvement in the prognosis of Hodgkin's disease and the other malignant lymphomas.

    Hodgkin and Huxley (HH) discovered that voltages control ionic currents in nerve membranes. This led them to describe electrical activity in a neuronal membrane patch in terms of an electronic circuit whose characteristics were determined using empirical data. Due to the complexity of this model, a variety of heuristics, including relaxation oscillator circuits and integrate-and-fire models, have been used to investigate activity in neurons, and these simpler models have been successful in suggesting experiments and explaining observations. Connections between most of the simpler models had not been made clear until recently. Shown here are connections between these heuristics and the full HH model. In particular, we study a new model (Type III circuit): It includes the van der Pol-based models; it can be approximated by a simple integrate-and-fire model; and it creates voltages and currents that correspond, respectively, to the h and V components of the HH system.

    Gene expression profiling studies based on DNA microarrays have demonstrated their ability to define the interaction pathways between neoplastic and nonmalignant stromal cells in cancer tissues. During the past ten years, a number of approaches including microdissection have tried to resolve the variability in DNA microarray measurements stemming from cancer tissue sample heterogeneity. Another approach, designated as virtual or in silico microdissection, avoids the laborious and time-consuming step of anatomic microdissection. It consists of confronting the gene expression profiles of complex tissue samples to those of cell lines representative of different cell lineages, different differentiation stages, or different signaling pathways. This strategy has been used in recent studies aiming to analyze microenvironment alterations using gene expression profiling of nonmicrodissected classical Hodgkin lymphoma tissues in order to generate new prognostic factors. These recent contributions are detailed and discussed in the present paper. PMID:21197104

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare entity that accounts for less than 5% of the cases of Hodgkin lymphoma (HL) with morphological, immunophenotypical, genetic and clinical behavior traits different from the classic HL. In a minority of patients, the NLPHL course is complicated by a transformation to a non-Hodgkin diffuse large B-cell lymphoma (NHDLBCL) with prognostic and therapeutic implications. Early metabolic changes observed by (18)F-FDG PET in patients with HL and NHL, after 1-3 cycles of chemotherapy, predict the final response to treatment and progression-free survival. In the case we are presenting herein, whether NLPHL is transformed to NHDLBCL or the two types of lymphoma co-exist in the same patient, the (18)F-FDG PET/CT scan was crucial for the identification of tumor resistance to first line chemotherapy and to guide a second biopsy decision and therefore modify the chemotherapy regimen.

    The thyroid gland is commonly included in the field of radiation therapy for patients with malignant lymphoma and with head and neck tumors. The radiation dose for malignant diseases varies considerably depending on the purpose of treatment and the institutional policies. A substantial number of these patients are developing subclinical and clinical hypothyroidism. The risk of developing hypothyroidism after a moderate radiation dose of 2000 to 4500 rads has been reported to be 10 to 20 percent. In addition, subclinical hypothyroidism is induced further in one third of the patients. There are also suggestions that external irradiation of the thyroid gland in patients with malignant lymphomas, as well as internal irradiation with radioiodine of the normal and hyperthyroid human thyroid glands, would induce elevations of serum antithyroid autoantibody titers. However, only a few cases of Graves disease following irradiation to the thyroid gland have been reported. We encountered a young woman who received radiation therapy to the mantle field for her Hodgkin's disease and developed hypothyroxinemia without overt signs and symptoms of hypothyroidism, followed by appearance of nodular goiter and then full-blown Graves disease.

    The management of pregnant women with active Hodgkin's disease (H.D.) should be individualized depending on the stage, the presence of infradiaphragmatic involvement, and age of gestation. Seventeen women aged 16-31 years with coexisting H.D. and pregnancy were followed between 1969 and 1982. H.D. was diagnosed during pregnancy in 15 patients and two became pregnant while on treatment. Seven women whose pregnancies were allowed to proceed uninterrupted were irradiated to supradiaphragmatic sites to doses of 1500-2000 rad during the second or third trimester; all had full term spontaneous normal deliveries and normal infants. Fetal doses ranged from 2-50 rad. Two patients treated with Vinblastine throughout three pregnancies delivered normal full term infants. Pregnancy was interrupted in six patients at 6-20 weeks of gestation for various reasons. In spite of several months delay in initiation of definitive therapy, the outcome of H.D. was not adversely affected in the majority of uninterrupted pregnancies as evidenced by long term disease-free survivals of 6-11 years in four of seven patients who were irradiated; the children now aged 6-11 years are also alive and reported normal.

    The middle of the 20th century hailed the realization that patients with Hodgkin disease could be cured. Through the groundbreaking work of Vera Peters, patients with a localized form of the disorder, previously thought to be incurable, were shown to be cured by extended-field radiotherapy. This important observation, although not immediately accepted, opened the minds of physicians to take more positive investigative and therapeutic approaches. Peters also introduced and championed the concept of tumour staging in Hodgkin disease and the use of prognostic factors in clinical decision-making. This novel approach led to high cure rates with radiotherapy in localized disease and provided a scientific basis for the subsequent use of chemotherapy in disseminated disease, resulting in a very high cure rate in patients with all stages of Hodgkin disease.

    The probability of maintaining ovarian function, becoming pregnant, and delivering a normal child is important to young women anticipating successful therapy for Hodgkin's disease. In this study, reproductive function was retrospectively examined in 103 women 40 years old or younger who had undergone treatment for Hodgkin's disease with total-lymphoid irradiation (TLI) alone, combination chemotherapy, or combined TLI and chemotherapy. Infertility was directly related to gonadal exposure to therapy and to age at treatment. Twenty women became pregnant after receiving total-nodal irradiation or combination chemotherapy or both. No fetal wastage occurred, and no birth defects were seen in the 24 infants born to these women. Even after intensive treatment programs, women successfully treated for Hodgkin's disease have become pregnant and delivered phenotypically normal children.

    Fulminant hepatic failure (FHF) is a relatively rare manifestation of Hodgkin's lymphoma. Clinical features, laboratory findings, and imaging of the liver are usually inconclusive, and liver biopsy may be required for confirmation. We present a case of an FHF in a woman 1 week after the diagnosis of Hodgkin's lymphoma. Chemotherapy could not be instituted due to hepatic encephalopathy and other complications. Autopsy revealed diffuse infiltration of the liver parenchyma. This case illustrates the importance of early diagnosis and institution of chemotherapy, which may reverse the liver failure.

    Purpose: To quantify the incidence of thyroid cancer after Hodgkin lymphoma (HL) and determine disease characteristics, risk factors, and treatment outcomes. Methods and Materials: Thyroid cancer cases were retrospectively identified from a multi-institutional database of 1981 HL patients treated between 1969 and 2008. Thyroid cancer risk factors were evaluated by a Poisson regression model. Results: With a median follow-up duration of 14.3 years (range, 0-41.2 years), 28 patients (1.4%) developed a thyroid malignancy. The overall incidence rate (expressed as the number of cases per 10,000 person-years) and 10-year cumulative incidence of thyroid cancer were 9.6 and 0.26%, respectively. There were no observed cases of thyroid malignancy in patients who received neck irradiation for HL after age 35 years. Age <20 years at HL diagnosis and female sex were significantly associated with thyroid cancer. The incidence rates of females aged <20 at HL diagnosis in the first 10 years, ?10 years, ?15 years, and ?20 years after treatment were 5, 31, 61, and 75 cases per 10,000 person-years of follow-up, respectively. At a median follow-up of 3.5 years after the thyroid cancer diagnosis, 26 patients (93%) were alive without disease, 1 (4%) was alive with metastatic disease, and 1 (4%) died of metastatic disease, at 6 and 3.6 years after the thyroid cancer diagnosis, respectively. Conclusions: Although HL survivors have an increased risk for thyroid cancer, the overall incidence is low. Routine thyroid cancer screening may benefit females treated at a young age and ?10 years from HL treatment owing to their higher risk, which increases over time.

    As a heterogeneous kind of malignances, Non-Hodgkin lymphoma (NHL) is the most common hematologic cancer worldwide with the significantly increased morbidity in China. Accumulated evidences demonstrated that oncoprotein MDM4 plays a crucial role in the TP53 tumor suppressor signaling pathway. An rs4245739 A>C polymorphism locating in the MDM4 3?-untranslated region creates a miR-191 target site and results in allele-specific MDM4 expression. In this study, we examined the association between this polymorphism as well as the TP53 Arg72Pro (rs1042522 G>C) genetic variant and Non-Hodgkin Lymphoma (NHL) risk in a Chinese Han population. Genotypes were determined in 200 NHL cases and 400 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by logistic regression. We found significantly increased NHL risk among carriers of the TP53 72Pro allele compared with those with the 72Arg allele (P?=?0.002 for the Pro/Pro genotype). We also observed a significantly decreased NHL risks among carriers of the MDM4 rs4245739 C allele compared with those with the A allele in Chinese (P?=?0.014 for the AC genotype). Stratified analyses revealed the associations between these SNPs and NHL risk are especially noteworthy in young or male individuals. Additionally, the associations are much pronounced in NHL patients with B-cell lymphomas or grade 3 or 4 disease. Our results indicate that the TP53 Arg72Pro and the MDM4 rs4245739 polymorphisms contribute to NHL susceptibility and support the hypothesis that genetic variants in the TP53 pathway genes can act as important modifiers of NHL risk.

    Hodgkin’s lymphoma (HL) is one of the most curable malignant diseases in adults. However, HL patients have a higher risk of developing second malignancies compared with the general population. The population of adult cancer survivors is growing, thus, the long-term effects of cancer treatment, including secondary cancer development, have become an increasingly important concern in the field of oncology. The current study presents the case of a female HL survivor who developed two secondary malignancies within 29 years of follow-up. Furthermore, a review of the literature was conducted, which focused on secondary breast and gastrointestinal cancers in HL survivors. PMID:25621073

    Hodgkin’s lymphoma (HL) originates from clonal B cells and is the most common malignancy in the second decade of life. Liver involvement is uncommon at presentation in patients with HL and there is a paucity of data for treatment of patients with severely impaired liver function. We present an unusual case of HL with severe hepatic impairment, splenomegaly and multiple chromosomal abnormalities that was treated initially with gemcitabine and steroids. Once liver function tests improved, six cycles of Adriamycin, bleomycin, vinblastine, and dacarbazine were administered. The patient remains in remission at 3.5 years of follow-up. PMID:25848330

    Hodgkin lymphoma (HL) is an uncommon monoclonal lymphoid malignancy consisting of 2 main entities: classical HL and nodular lymphocyte predominant. Hodgkin lymphoma usually presents with peripheral lymphadenopathies, while extranodal involvement is rare. Prevalent osseous presentation is rare and still misdiagnosed, despite improvements in diagnostic techniques. Here we report the case of a 30-year-old man with multifocal HL bone involvement initially misdiagnosed as chronic recurrent osteomyelitis. This case emphasizes the difficulties in the diagnosis of HL presenting with bone pain and with radiologic skeletal findings not specific for lymphoma. These patients often have diagnostic delays and misdiagnosis. Repeated investigations and clinical suspicion of unusual presentations may be helpful in order to establish a correct diagnosis and start an effective treatment in this highly curable disease.

    Non-Hodgkin lymphoma (NHL) includes a group of more than 20 different malignant lymphoproliferative diseases that originate from lymphocytes. Rates of NHL have increased dramatically over the past few decades, although the rate of increase has recently slowed. It is now the sixth most common cancer in Australia. Globally, it is somewhat more common in men than in women, and rates are highest in North America and Australia. The causes of the increase in NHL rates are largely unknown. The best described risk factor for NHL is immune deficiency; rates of NHL are greatly increased, with relative risks of 10-100 or more, in people with immune deficiency associated with immune suppressive therapy after transplantation, HIV/AIDS, and congenital conditions. In addition, some NHL subtypes are associated with specific infections. These include immune-deficiency-associated central nervous system NHL (Epstein-Barr virus); gastric mucosa-associated lymphoid tissue NHL (Helicobacter pylori); adult T-cell leukemia/lymphoma (human T-lymphotrophic virus type 1) and body cavity-based lymphoma (human herpesvirus 8). However, these specific infections account for a very small proportion of total NHL incidence. In addition to immune deficiency and infection, other immune-related conditions are increasingly being recognised as related to NHL risk. Specific autoimmune conditions, including rheumatoid arthritis, systemic lupus erythema, Sjogren's syndrome, psoriasis and coeliac disease are associated with moderately increased risk of NHL. On the other hand, allergic and atopic conditions and their correlates such as early birth order, appear to be associated with a decreased risk of NHL.A variety of other exposures are less strongly related to NHL risk. These include occupational exposures, including some pesticides, herbicides, and solvents. Recently, two studies have reported that sun exposure is associated with a decreased risk of NHL. Smoking appears to be weakly positively associated with risk of follicular NHL, and alcohol intake is associated with a decreased risk of NHL. The pooled analysis of several case-control studies of NHL risk that are currently in the field promises to help clarify which of these risk factors are real, and will contribute to the elucidation of the mechanisms of how disorders of the immune system, and other factors, are related to NHL risk.

    BACKGROUND: Non-Hodgkin lymphoma has increased in frequency over the past 30 years, and is a common cancer in HIV-1-infected patients. Although no definite risk factors have emerged, a viral cause has been postulated. Polyomaviruses are known to infect human beings and to induce tumours in laboratory animals. We aimed to identify which one of the three polyomaviruses able to infect human beings (simian virus 40 [SV40], JC virus, and BK virus) was associated with non-Hodgkin lymphoma. METHODS: We analysed systemic non-Hodgkin lymphoma from 76 HIV-1-infected and 78 HIV-1-uninfected patients, and non-malignant lymphoid samples from 79 HIV-1-positive and 107 HIV-1-negative patients without tumours; 54 colon and breast carcinoma samples served as cancer controls. We used PCR followed by Southern blot hybridisation and DNA sequence analysis to detect DNAs of polyomaviruses and herpesviruses. FINDINGS: Polyomavirus T antigen sequences, all of which were SV40-specific, were detected in 64 (42%) of 154 non-Hodgkin lymphomas, none of 186 non-malignant lymphoid samples, and none of 54 control cancers. This difference was similar for HIV-1-infected patients and HIV-1-uninfected patients alike. Few tumours were positive for both SV40 and Epstein-Barr virus. Human herpesvirus type 8 was not detected. SV40 sequences were found most frequently in diffuse large B-cell and follicular-type lymphomas. INTERPRETATION: SV40 is significantly associated with some types of non-Hodgkin lymphoma. These results add lymphomas to the types of human cancers associated with SV40.

    A generalization of non-Abelian gauge theories of compact Lie groups is developed by gauging the noncompact group of volume-preserving diffeomorphisms of a D-dimensional space R{sup D}. This group is represented on the space of fields defined on M{sup 4}xR{sup D}. As usual the gauging requires the introduction of a covariant derivative, a gauge field, and a field strength operator. An invariant and minimal gauge field Lagrangian is derived. The classical field dynamics and the conservation laws of the new gauge theory are developed. Finally, the theory's Hamiltonian in the axial gauge and its Hamiltonian field dynamics are derived.

    Tissue specimens from 198 cases of Hodgkin's disease and 151 non-Hodgkin lymphomas, as well as 34 nonmalignant lymph node biopsies were examined for the presence of Epstein-Barr virus (EBV) DNA by polymerase chain reaction. Epstein-Barr virus-specific DNA sequences were detected in DNA extracts from frozen and/or paraffin-embedded tissues of 58% of Hodgkin's disease cases. High and low grade non-Hodgkin lymphomas as well as chronic lymphocytic leukemia biopsies contained EBV DNA in 26%, 14%, and 7% of the cases, respectively. Ten percent of the control lymph nodes with normal histology were EBV positive. In Hodgkin's disease biopsies, subsequent in situ hybridization revealed an exclusive localization of the viral DNA in the tumor cells. These findings suggest an involvement of EBV in the pathogenesis of Hodgkin's disease in a substantial proportion of cases. Images Figure 1 Figure 2 PMID:2164775

    Aims—To analyse the latent membrane protein-1 (LMP-1) gene in a series of patients with Epstein-Barr virus (EBV) positive LMP expressing ordinary and HIV associated Hodgkin's disease to detect possible genetic alterations and particularly the existence of deletions near the 3? end of the gene. Methods—Expression of the EBV LMP-1 was assessed using immunohistochemistry in 186 cases of Hodgkin's disease and 31 cases of HIV associated Hodgkin's disease. Genomic DNA was extracted from frozen lymph node biopsy specimens from 25 cases of Hodgkin's disease and 11 of HIV associated Hodgkin's disease, all of whom expressed the LMP-1 protein within diagnostic Hodgkin and Reed-Sternberg (HRS) cells, and amplified by polymerase chain reaction (PCR) using primers specific for the different LMP-1 regions. Results—LMP-1 expression was observed in 106 of 186 Hodgkin's disease cases and in all 31 HIV associated Hodgkin's disease cases. Molecular analysis of the LMP-1 gene showed a high degree of genetic heterogeneity in the carboxy-terminal domain compared with the prototype B95-8 EBV strain, specially in the patients with HIV associated Hodgkin's disease. Variation in the size of the repeated region was found in 17 of 25 Hodgkin's disease and nine of 11 HIV associated Hodgkin's disease cases. Deletions of 30 base pairs near the 3? end of the gene were detected in all cases of HIV associated Hodgkin's disease and in six Hodgkin's disease. In one case of Hodgkin's disease a larger deletion was observed. In all patients with LMP-1 deletion mutants, 50-90% of the diagnostic HRS cells expressed the LMP-1 protein. Conclusions—The presence of the 30 base pair deletion in all cases of HIV associated Hodgkin's disease supports previous studies that reported aggressive histological and clinical behaviour in tumours harbouring this deletion. This deletion may prolong the half-life of the protein which would explain the high levels of LMP-1 expressing HRS cells in those cases carrying LMP-1 deletions. That the 30 base pair deletion was present in all of the HIV associated Hodgkin's disease specimens suggests that impairment of immune function is a stringent requirement for the expansion of malignant cells infected by EBV strains containing the deleted LMP-1 gene.

    Although Hodgkin's lymphoma is considered a highly curable cancer, a substantial portion of patients will be refractory or will relapse after first-line therapies and even after subsequent autologous stem cell transplantation. With the absence of effective salvage therapies, these patients carry a poor prognosis with dismal survival. In this therapeutic void, the antibody-drug conjugate brentuximab vedotin was introduced and has since yielded impressive and durable response with minimal and reversible toxicity. Such efficacy in the relapse-refractory setting has led to new hypotheses and dramatic changes in our treatment strategies of Hodgkin's lymphoma. Numerous clinical trials evaluating brentuximab in the frontline and various other treatment settings are forthcoming and will demonstrate the full extent of the drug's impact. PMID:25967932

    Brentuximab vedotin has emerged as a useful treatment option for relapsed or refractory Hodgkin's lymphoma; however, uncommon cases of anaphylactic reactions may require its permanent discontinuation. We report a 29-yr-old woman with refractory Hodgkin's lymphoma, who developed an anaphylactic reaction during the second dose of brentuximab vedotin. A 12-step desensitization protocol was followed; after premedicating with antihistaminic agents, methylprednisolone and montelukast, a total dose of 156 mg of brentuximab vedotin (1.8 mg/kg) was given as three infusions with increasing rate and concentration. Such desensitization protocol can allow safe administration of brentuximab vedotin and may have a broader applicability in managing hypersensitivity reactions with other monoclonal antibodies.

    Pediatric nephrotic syndrome (NS) is most often idiopathic or primary but in rare cases, it can be secondary to neoplasia. We report on a case of steroid-resistant NS revealing as a paraneoplastic syndrome of Hodgkin disease (HD) in a 12-year-old boy. The onset of the NS can be earlier, later, or simultaneous to the HD. Treatment of the lymphoma allows the disappearance of the NS. In the case we observed, the diagnosis of HD was delayed because HD presented with an isolated, hilar adenopathy in the absence of retroperitoneal or peripheral locations. In children aged 10 years or more presenting with NS, steroid-resistant or otherwise, a possible paraneoplastic origin such as Hodgkin lymphoma should always be taken into consideration and eventually eliminated.

    It is commonly believed that cytodiagnosis of Hodgkin's lymphoma (HL) is much easier than that of non-Hodgkin lymphoma (NHL). However, recognition of certain NHL subtypes with Reed-Sternberg (R-S)-like cells and results of immunohistochemical studies point to the contrary. To study the limitations of cytology in diagnosis of HL, fine-needle aspiration (FNA) smears of 130 lymphoma or suspected lymphoma cases were reviewed. Initial and reviewed cytodiagnoses were compared with histopathology in 89 cases. Immunocytochemical and immunohistochemical studies were performed in 56 and 59 cases, respectively. Among histologically diagnosed HL cases, definitive cytodiagnosis of HL (initial as well as reviewed) was significantly less frequent than cytodiagnosis of NHL among histologically diagnosed NHL cases (P = 0.0328 and = 0.0001, respectively). On the other hand, cytologically diagnosed HL/NHL cases were significantly more frequent in the former group (P = 0.0001 and = 0.0018, respectively). ALCL and TCRBCL were the two NHL subtypes which created confusion with HL in FNA smears. Twenty-one cytohistological concordant HL cases and equal number of discordant cases were compared. When compared with discordant group, the patients in concordant group were significantly younger (P = 0.045). Hodgkin/Hodgkin-like cells and typical R-S cells were significantly more frequent in FNA smears of the concordant group (P = 0.0478 and = 0.0431, respectively). Immunocytochemical and immunohistochemical studies showed good correlation with histological diagnosis of HL. It is suggested that proper interpretation of cytologic features, together with use of immunocytochemical parameters can help in reducing the margin of error in cytodiagnosis of HL. PMID:19373880

    Findings of CT of the spleen were compared with those of histologic examination in 35 patients who had Hodgkin disease. CT provides a simple way to calculate splenic size. This index is also of value in the assessment of the histologic state of the spleen. An accuracy rate of 91%, specificity of 94%, and a sensitivity of 89% in diagnosing splenic localization of lymphoma was found in this study.

We have since evaluated splenic size and function in 25 patients who had received splenic irradiation 5 to 16 years previously either for Hodgkin's disease (n = 19) or non-Hodgkin's lymphoma (n = 6). Mean maximum splenic diameter as measured on a /sup 99//sup m/Tc-sulfur colloid liver-spleen scan was 6.2 cm in the irradiated group and 9.7 cm in a control group (p < 0.001). The mean percentage of erythrocytes containing pits when observed with interference phase microscopy was 13.0% in the irradiated group, which was significantly different (p < 0.001) from the levels found in each of the control groups: normal subjects, 0.9%; unstaged and untreated lymphoma patients, 0.6%; and patients after splenectomy, 33.7%. Patients who have had splenic irradiation should be considered at risk of developing overwhelming pneumococcal sepsis.

    Introduction In addition to their important role in fighting infection, natural killer cells are cytotoxic to cancer cells. Studies demonstrated that some KIR genes were responsible for the reduction of the risk of Hodgkin's lymphoma (HL) while others were associated with an increased risk of HL. Aim The aim of this study is to assess KIR genotypic distribution in Lebanese patients with Hodgkin's lymphoma. Methods KIR genotype was analyzed in 41 HL patients and 120 healthy Lebanese individuals using the KIR Genotyping SSP kit. Results No significant association between HL and any KIR gene was found. Among HL patients, the AA, AB, and BB genotype frequencies were, respectively, 41.46%, 43.9% and 14.63% with an A:B ratio of 1.73:1. As for the controls, the AA, AB, and BB genotype frequencies were, respectively, 39.17%, 50%, and 10.83% with an A:B ratio of 1.79:1. Conclusion In this first study from the Mediterranean region, KIR genotype does not seem to be associated with Hodgkin's lymphoma. Further clinical and translational research is needed to rule out the protective or predisposing role of KIR genes in this important clinical entity. PMID:25853061

  13. Action potential initiation in the hodgkin-huxley model.

    A recent paper of B. Naundorf et al. described an intriguing negative correlation between variability of the onset potential at which an action potential occurs (the onset span) and the rapidity of action potential initiation (the onset rapidity). This correlation was demonstrated in numerical simulations of the Hodgkin-Huxley model. Due to this antagonism, it is argued that Hodgkin-Huxley-type models are unable to explain action potential initiation observed in cortical neurons in vivo or in vitro. Here we apply a method from theoretical physics to derive an analytical characterization of this problem. We analytically compute the probability distribution of onset potentials and analytically derive the inverse relationship between onset span and onset rapidity. We find that the relationship between onset span and onset rapidity depends on the level of synaptic background activity. Hence we are able to elucidate the regions of parameter space for which the Hodgkin-Huxley model is able to accurately describe the behavior of this system. PMID:19148265

    Cardiac tumors are rare entities in clinical practice, with an incidence of 0.05%. Approximately 75% are benign and 25% malignant. Among these, Lymphomas are uncommon, representing about 0.25%. The non-Hodgkin lymphomas can occur in extranodal tissues in 20% of the cases and 80% of these non-Hodgkin lymphomas are composed of diffuse B cells. The extranodal presentation is most frequent in young adults, with a high degree of malignancy and rapid growth. It can present with primary infiltration of various organs; cardiac involvement occurs in 20 to 28% of cases, usually located in the right chambers and with nonspecific symptoms, depending on the location and extent of the tumor. The diagnostic test in these cases is undoubtedly the biopsy of the lymph node or the affected tissue. We present the case of non-Hodgkin disease of diffuse large cells, with right intra-atrial involvement in a 23-year-old-female patient, who presented with progressive dyspnea. A transesophageal echocardiography was performed and an intra-atrial tumor mass was detected. A biopsy was performed, by femoral venous catheterization, allowing the establishment of the histopathological diagnosis and treatment. At a one year follow up, the patient shows complete remission.

    Stage I lymphocyte-predominant Hodgkin's disease was diagnosed in a 44-month-old girl. Although immune deficiency was suspected and IgA deficiency demonstrated, the diagnosis of an ataxia-telangiectasia (AT)-like syndrome was not confirmed until eight weeks later when results of studies on the radiosensitivity of cultured skin fibroblasts were available. The child had none of the usual physical stigmata of AT. Severe acute radiation damage followed the treatment of this child with standard doses of radiation therapy. Clinical, pathologic, and radiobiologic correlations are drawn. The diagnosis of a malignant lymphoma disorder in children under the age of five should alert clinicians to the possibility of immune deficiency and, even in the absence of classical physical signs, to AT in particular. Suggestions for the management of future similar cases are put forward.

    Niels Bohr famously insisted on the indispensability of what he termed "classical concepts." In the context of the decoherence program, on the other hand, it has become fashionable to talk about the "dynamical emergence of classicality" from the quantum formalism alone. Does this mean that decoherence challenges Bohr's dictum—for example, that classical concepts do not need to be assumed but can be derived? In this paper we'll try to shed some light down the murky waters where formalism and philosophy cohabitate. To begin, we'll clarify the notion of classicality in the decoherence description. We'll then discuss Bohr's and Heisenberg's take on the quantum—classical problem and reflect on different meanings of the terms "classicality" and "classical concepts" in the writings of Bohr and his followers. This analysis will allow us to put forward some tentative suggestions for how we may better understand the relation between decoherence-induced classicality and Bohr's classical concepts.

    In this article we try to answer the question how and why did Chinese ancient astronomy came into being and how did one lonesome and original calendar system on the very end of the world develop. At the beginning, Chinese people distinguished time of the year by the annual cycles of plants and animals, but soon began to determine seasons by observing celestial bodies. Early successful measuring of tropical year and synodic month made possible for Chinese people to issue first calendars very early. Spring and Autumn (Chunqiu) period (770 - 476 BC) brought forward first official calendars. Further improvement of calendars is due to the development of new astronomical instruments. Chinese calendars also originate from the metaphysical concepts of Qi, Yin-Yang and 5 elements. 5 elements were connected with Chinese 5 seasons of the year and this was the first form of solar calendar. Later, it developed into solar calendar with 10 months. In the next phase, Chinese calendar turned into lunisolar calendar which also has its evolution. Chinese people invented Calendar "with division by four" (the name of this calendar). They also added 24 solar terms to make calendar harmonize with natural cycles. Li Chunfeng rearranged intercalations and used month without main solar term and divided months into short and long months. Sexagesimal system of time measuring refers to the system of Chinese 10 Heavenly Stems and 12 Earthly Branches. Its purpose is to measure time and define years, months, days and hours.

    The dynamics of a spiking neuron approaching threshold is investigated in the framework of Markov-chain models describing the random state-transitions of the underlying ion-channel proteins. We characterize subthreshold channel-noise-induced transmembrane potential fluctuations in both type-I (integrator) and type-II (resonator) parametrizations of the classic conductance-based Hodgkin-Huxley equations. As each neuron approaches spiking threshold from below, numerical simulations of stochastic trajectories demonstrate pronounced growth in amplitude simultaneous with decay in frequency of membrane voltage fluctuations induced by ion-channel state transitions. To explore this progression of fluctuation statistics, we approximate the exact Markov treatment with a 12-variable channel-based stochastic differential equation (SDE) and its Ornstein-Uhlenbeck (OU) linearization and show excellent agreement between Markov and SDE numerical simulations. Predictions of the OU theory with respect to membrane potential fluctuation variance, autocorrelation, correlation time, and spectral density are also in agreement and illustrate the close connection between the eigenvalue structure of the associated deterministic bifurcations and the observed behavior of the noisy Markov traces on close approach to threshold for both integrator and resonator point-neuron varieties.

    An altered anti–Epstein-Barr virus (EBV) serologic profile preceding diagnosis is associated with an increased risk of Hodgkin lymphoma. It is unknown whether this atypical pattern predicts Hodgkin lymphoma risk further subdivided by determination of EBV in tumor cells. A nested case-control study of 128 incident Hodgkin lymphoma cases and 368 matched controls from active-duty military personnel with archived serum in the US Department of Defense Serum Repository was conducted to determine whether a panel of anti-EBV antibody titers differed in EBV+ and EBV? Hodgkin lymphoma. Among 40 EBV+ Hodgkin lymphoma cases and matched controls, statistically significant increased risks were associated with elevated anti-EBV VCA IgG antibody titers (relative risk = 3.1; 95% confidence interval [CI], 1.1-8.7), and an anti–EBNA-1/anti–EBNA-2 antibody ratio ? 1.0 versus > 1.0 (relative risk = 4.7; 95% CI, 1.6-13.8). In contrast, no significant associations were found among 88 EBV? Hodgkin lymphoma cases relative to their matched controls. In case-case analysis, EBV+ disease was significantly associated with a low anti–EBNA-1/anti–EBNA-2 antibody ratio. This distinc-tive serologic response to EBV latent antigens, indicative of immune dysfunction in other clinical settings, is associated with an increased risk of developing EBV+ but not EBV? Hodgkin lymphoma. PMID:22972983

    Plant sources of some traditional Chinese herbs may have changed over time. History records of herbal toxicity should be viewed critically when different plants might have been used under the same name in earlier eras. The current main source of the Chinese herb Mu Tong is Aristolochia manshuriensis. Examination of classical Chinese herbal literature revealed that until the mid 17th century the original source plants of Mu Tong had been several Akebia species. From the 17th century until the early 20th century Clematis species were the main source of Mu Tong. A manshuriensis has only been widely used since the 1950s. Renal failure due to ingestion of large doses of A. manshuriensis has been reported in China and other countries while no such toxicity has been recorded in traditional Chinese herbal texts. Documentation of traditional Chinese herbal literature should help to ensure the safe use of Chinese herbs. PMID:12503251

    The mdm-2 protein is a 90-kD protein that forms a complex with the p53 protein, enabling cells from some human neoplasms to overcome the growth-suppressing activity of p53. Most non-Hodgkin's lymphomas lack p53 mutations, and the mechanism of inactivation of tumor suppressive function remains obscure. To assess the role of mdm-2 in lymphomagenesis, 22 cases were evaluated for mdm-2 gene amplification or rearrangement in Southern blots. Localization of the mdm-2 protein was performed on cryostat sections and compared with expression of the p53 gene product. No case exhibited mdm-2 gene amplification or rearrangement, but overexpression of nuclear mdm-2 gene protein product was found in three of six diffuse large cell (B-cell immunoblastic) lymphomas (30-70% of the tumor cells stained). The mdm-2 protein was absent from low- and intermediate-grade lymphomas with the exception of a few cells (5% or less) in four cases. The mdm-2-positive cases stained negative for p53. Southern blot analysis showed that samples overexpressing mdm-2 did not have amplification or rearrangement of the gene. In summary, amplification of the mdm-2 gene does not appear to play a prominent role in the pathogenesis of non-Hodgkin's lymphomas, although overexpression of the protein gene product occurs, particularly in high-grade neoplasms.

    The lifespan of AIDS patients has increased as a result of aggressive antiretroviral therapy, and the incidences of the AIDS-defining cancers, Hodgkin's lymphoma and Kaposi sarcoma, are declining, Still, the increased longevity of AIDS patients is now associated with increased incidence of other cancers, including Hodgkin's lymphoma (HL). In order to determine if we could identify biomarkers for the early detection of HL, we undertook an accurate mass and elution time tag proteomics analysis of individual plasma samples from AIDS patients without HL (n=14) and with HL (n=22). This analysis identified 33 proteins, included C-reactive protein and three serum amyloid proteins, that were statistically (p<0.05) altered by at least 1.5-fold between the two groups. At least three of these proteins have previously been reported to be altered in the blood of HL patients. Ingenuity Pathway Analysis software identified 'inflammatory response' and 'cancer' as the top two, biological functions commonly associated with these proteins. The clear association of these proteins with cancer and inflammation suggests that they are truly associated with HL and that they would be useful in the detection of this disease.

  16. Leu 7 (CD57) reactivity distinguishes nodular lymphocyte predominance Hodgkin's disease from nodular sclerosing Hodgkin's disease, T-cell-rich B-cell lymphoma and follicular lymphoma.

    Several recent reports have suggested that nodular lymphocyte predominance Hodgkin's disease (NLPHD) may be distinct from other forms of Hodgkin's disease and may be more closely related to B-cell non-Hodgkin's lymphoma. This is primarily based on immunophenotypic studies that have shown that the L & H cells in NLPHD demonstrate a B-cell phenotype. In 1989, Poppema reported that the T cells in NLPHD differ from T cells in other forms of Hodgkin's disease in that they demonstrate reactivity for Leu 7 (CD57). In this study we tested the hypothesis that Leu 7 (CD57) reactivity of small lymphocytes in NLPHD is an immunophenotypic feature that distinguishes NLPHD from nodular sclerosing Hodgkin's disease and from certain B-cell lymphomas that may histologically simulate NLPHD, namely T-cell-rich B-cell lymphoma and follicular lymphoma. Using an image analysis method, we found Leu 7 (CD57) reactivity in an average of 18.9% of the small lymphocytes in the nodules of NLPHD compared with 3.9% in nodular sclerosing Hodgkin's disease, 4.3% in T-cell-rich B-cell lymphoma, and 2.1% in follicular lymphoma. Moreover, Leu 7 (CD57)-reactive small lymphocytes often showed a distinctive pattern in NLPHD, forming a ring of cells around the large L & H cells. While scattered Leu 7 (CD57)-reactive lymphocytes were found in the other disorders, the percentage of reactive cells and the pattern of reactivity were significantly different in NLPHD. These results suggest that Leu 7 (CD57) reactivity may be used as an additional immunophenotypic criterion in distinguishing NLPHD from nodular sclerosing Hodgkin's disease, T-cell-rich B-cell lymphoma, and follicular lymphoma. The clinical and biological significance of Leu 7 (CD57) reactivity of small lymphocytes in NLPHD merits further investigation. Images Figure 1 Figure 2 PMID:7679553

    Accurate clinical staging is crucial for adequate risk-adapted treatment in Hodgkin lymphoma (HL) to prevent patients from under- or over-treatment. Within the latest German Hodgkin Study Group trial generation, diagnostic findings such as histopathology, computerized tomography imaging and clinical risk factors were re-evaluated by expert panels. Here, we retrospectively analysed 5965 patients and identified 399 in who major discordant findings changed their first-line treatment allocation. Histopathology review did not confirm the initial diagnosis of HL in 87 patients. Treatment allocation was revised in 312 of the remaining 5878 patients: 176 were assigned to a higher and 128 to a lower risk group, respectively; the correct treatment group remained unclear in 8 patients. Cases of revised treatment allocation accounted for 9·8%, 6·0%, 0·8%, and 14·8% of patients initially assigned to the HD13, HD14, HD15 trials and stage IA lymphocyte-predominant HL project, respectively. Most revisions were due to wrong application of clinical stage (20·5% of 312 patients with revised treatment group), histological subtype (9·0%) or the risk factors ?3 involved areas (46·8%) or large mediastinal mass (9·3%). In conclusion, centralized review by experienced experts changed risk-adapted first-line treatment in a relevant proportion of HL patients. Quality control measures clearly improve the accuracy of treatment and should be implemented in clinical practice. PMID:26310520

  1. Chinese Tallow: Invading the Southeastern Coastal Plain

    Chinese tallow is an ornamental tree with colorful autumn foliage that can survive full sunlight and shade, flooding, drought, and in some cases fire. To horticulturists this kind of tree sounds like a dream, but to ecologists, land managers, and land owners this kind of tree can be a nightmare, especially when it invades an area and takes over native vegetation. Chinese tallow (Triadica sebifera), a nonnative tree from China, is currently transforming the southeastern Coastal Plain. Over the last 30 years, Chinese tallow has become a common tree in old fields and bottomland swamps of coastal Louisiana. Several studies at the U.S. Geological Survey's National Wetlands Research Center (NWRC), Lafayette, Louisiana, are aimed at understanding the factors that contribute to Chinese tallow growth, spread, and management. When tallow invades, it eventually monopolizes an area, creating a forest without native animal or plant species. This tree exhibits classic traits of most nonnative invaders: it is attractive so people want to distribute it, it has incredible resiliency, it grows quickly and in a variety of soils, and it is resistant to pests. In the coastal prairie of Louisiana and Texas, Chinese tallow can grow up to 30 feet and shade out native sun-loving prairie species. The disappearing of prairie species is troublesome because less than 1% of original coastal prairie remains, and in Louisiana, less than 500 of the original 2.2 million acres still exist. Tallow reproduces and grows quickly and can cause large-scale ecosystem modification (fig. 1). For example, when it completely replaces native vegetation, it has a negative effect on birds by degrading the habitat. Besides shading out grasses that cattle like to eat, it can also be potentially harmful to humans and animals because of its berries (fig. 2) and plant sap that contain toxins. There is some concern its leaves may shed toxins that change the soil chemistry and make it difficult for other plants to grow.

    A 30-year-old white man with Stage IV B Hodgkin's disease, mixed cellularity type, developed leptomeningeal involvement shortly after relapsing on nitrogen mustard, Oncovin (vincristine), procarbazine, and prednisone (MOPP), and while receiving Adriamycin (doxorubicin), bleomycin, Velban (vinblastine), and dacarbazine (ABVD). Whole brain irradiation and intrathecal methotrexate were successfully incorporated into his treatment program. The patient has now been in complete remission for more than 40 months. A review of this rare complication of Hodgkin's disease is presented.

    The generation of spikes by neurons is energetically a costly process and the evaluation of the metabolic energy required to maintain the signalling activity of neurons a challenge of practical interest. Neuron models are frequently used to represent the dynamics of real neurons but hardly ever to evaluate the electrochemical energy required to maintain that dynamics. This paper discusses the interpretation of a Hodgkin-Huxley circuit as an energy model for real biological neurons and uses it to evaluate the consumption of metabolic energy in the transmission of information between neurons coupled by electrical synapses, i.e. gap junctions. We show that for a single postsynaptic neuron maximum energy efficiency, measured in bits of mutual information per ATP molecule consumed, requires maximum energy consumption. On the contrary, for groups of parallel postsynaptic neurons we determine values of the synaptic conductance at which the energy efficiency of the transmission presents clear maxima at relatively ver...

    Epidemiological studies suggest unique occurrence patterns of Hodgkin lymphoma (HL) worldwide. In most Western countries there is a clear bimodal age distribution with an early peak in young adults followed by a second peak in older adults, particularly among males. In the Middle East and Asia, HL is more common in early childhood. There also are marked racial differences in the presentations of HL and HL subtypes, and particular single nucleotide polymorphisms (SNPs) have been identified as etiological factors suggesting that gene-gene and gene-environment interactions are involved. Personal health choices such as exercise and smoking may modify an individual's chances of developing HL. Numerous studies highlight the impact that exposure to Epstein-Barr virus and other environmental factors have on HL risk. Understanding the relative importance of each of these findings and their links to HL development and survival will help clinical researchers expand curative therapies and create preventative strategies for HL.

    Immunological indices have been reassessed in 27 patients in remission from Hodgkin's disease for 5 years after treatment and the findings correlated with initial treatment and splenectomy status. Neutrophil counts were lower and lymphocyte and monocyte counts higher at 5 years' remission than at presentation; the increases in lymphocyte count were mainly a feature of the splenectomized patients. Neutrophil function (nitro-blue tetrazolium) was unchanged in remission but cellular immunity (leucocyte migration inhibition and lymphocyte transformation) was depressed at 5 years and progressive falls in serum immunoglobulins were noted. Low values of IgG and IgM were particularly found in patients who had splenectomy and chemotherapy; there was however no excess of infections in this small group. PMID:7138765

    We utilize the original Hodgkin-Huxley (HH) model to consider the effects of defective ion channels to the temporal response of neurons. Statistics of firing rate and inter-spike interval (ISI) reveal that production of action potentials (APs) in neurons is not sensitive to changes in membrane conductance for sodium and potassium ions, as well as to the reversal potential for sodium ions, as long as the relevant parameters do not exceed 13% from their normal levels. We also found that blockage of a critical fraction of either sodium or potassium channels (dependent on constant input current) respectively limits the firing activity or increases spontaneous spiking activity of neurons. Our model may be used to guide experiment designs related to ion channel control drug development.

    The thyroid function of 64 patients with Hodgkin's disease who received mantle irradiation during the period 1966 to 1976 was studied. More than two-thirds (44 to 64) had some thyroid dysfunction. Twenty had mild dysfunction manifested by an abnormal thyroid-stimulating hormone response to thyrotropin-releasing hormone. Twenty had what could be termed compensated hypothyroidism while four were overtly hypothyroid. The severity of dysfunction was not related to age, sex, or chemotherapy. We found, however, that decreased thyroid function was inversely proportional to the length of time between a diagnostic lymphangiogram and the radiation therapy. These results are consistent with the hypothesis that the iodine load of the lymphangiogram renders the thyroid gland more radiosensitive. Thyroxine suppression of the thyroid gland during the period from the lymphangiogram through the termination of radiation therapy is suggested as a means of avoiding thyroid injury.

    We are presenting a rare case of bilateral adrenal non-Hodgkin's lymphoma (NHL) that presented as a primary malignancy. An 83-year-old man presented with newly discovered bilateral adrenal incidentalomas, fatigue, and 30 pound weight loss. Of the 116 cases of primary adrenal NHL reported, over half have presented bilaterally and occur with adrenal insufficiency. Therefore, the finding of bilateral adrenal masses requires an urgent work-up of the functional status of the adrenal gland as well as a thorough analysis of the imaging characteristics seen on noncontrast computed tomography (CT) in order to maximize patient survival. Adrenal function testing was normal. Repeat CT imaging revealed rapidly growing lesions with high attenuations; both masses >10 HU. Histological examination of core biopsies discovered malignant lymphoma with no known past history of lymphoma. Our case coincides with the literature, which states that a mass with attenuation >10 HU in the adrenal glands has a high risk of malignancy. PMID:25837497

    Primary bone lymphoma (PBL) is a relatively uncommon entity. It represents approximately 5% of all non-Hodgkin lymphomas (NHLs) and 3% of all bone malignancies. The femur, tibia, and pelvis are the most common skeletal sites involved. It can occur at any age, with a peak incidence in the fourth and fifth decades.The most common grade identified is intermediate, followed by low-grade lesions. It can mimic other disease processes, especially infection. So, thorough and prompt investigatory workup is essential for adequate treatment. Localized disease responds well to combined modality treatment with chemotherapy and radiotherapy and is associated with good prognosis. We discuss the clinical findings, diagnosis, and treatment in a case of PBL involving the talus. This is an unique clinical presentation owing to its unusual site. PMID:26458619

    In the present study, the case of a patient with nodular sclerosing Hodgkin's lymphoma (NSHL) presenting with diffuse fibrosis of the bone marrow (BM) was reported. A 30-year-old male complained of fever for 1 year, as well as lumbago, lymph node swelling and night sweats for 3 months. A biopsy of the lymph nodes established a diagnosis of NSHL. Aspiration of BM was a dry tap, and the BM biopsy demonstrated marked myelofibrosis with increased proliferation of reticulin fiber. Multiple skeletal lesions were detected in the patient's vertebra, pelvis, sternum and bilateral femur by magnetic resonance imaging and computed tomography. Following numerous courses of chemotherapy and radiotherapy, remission of the lymphoma was achieved. Subsequently, the BM aspiration became possible, and BM biopsy demonstrated a reduction in fibrosis. PMID:26622707

    Pediatric patients with newly diagnosed, non-Hodgkin Lymphoma (NHL) have an excellent overall survival. However, therapy regimens are associated with acute toxicity and late effects. Furthermore, patients with relapsed or refractory disease have relatively few options with proven clinical benefit. Both histologic and molecular differences exist between adult and pediatric NHL preventing simple translation of adult NHL successes into improvements in pediatric NHL treatment. This review summarizes the introduction of targeted therapies into frontline treatments for patients with anaplastic large-cell lymphoma and CD20-positive tumors, with the goal of improving overall survival while limiting both short- and long-term toxicities. In addition, newer approaches that have limited data in children but may have a significant role in how we treat pediatric NHL in the future are reviewed, which include CD19 directed therapy, Notch inhibition, the tri-functional antibody, FBTA05, and EZH2 inhibition.

    Bronchiolitis obliterans organizing pneumonia (BOOP) represents a kaleidoscope of concepts and morphologies, often being confused with a series of conditions, among which the most feared are Hodgkin's lymphoma and bronchioloalveolar carcinoma. We shall present the case of a 56-year-old patient, diagnosed in August 2013 with a pulmonary tumour of the right upper lobe, which was CTstaged - T4N0M0 (IIIA), who underwent a video-assisted thoracotomy for histopathological confirmation. A mediastino-pulmonary formation had been detected intraoperatively and multiple biopsies had been collected. The information brought by the histopathological examination suggested the presence of 2 synchronous pathologies, namely: the mediastinal biopsy showed an advanced degree of dense, compact fibrosis and the pulmonary biopsy highlighted the presence of granulation tissue and Masson bodies in the distal airspace with destruction of vascular and alveolar structures, an aspect which was compatible with organizing pneumonia (BOOP). Once a diagnosis was established, an oral corticosteroid therapy was initiated (Prednisone 30 mg/day) over a period of one month, but the symptomatology of the patient worsened. A new thoracic CT carried out in November 2013 highlighted the progression and extension of the paramediastinal tumoral formation, exhibiting central necrosis and invading the mediastinal vessels, causing their compression (superior vena cava syndrome) associated with multiple mediastinal and hilar adenopathies. The non-favorable evolution and the extensive array of conditions that may mimic the BOOP histopathological pattern have been the key elements, which were the basis of our persistence in getting a real diagnosis. Therefore, in this respect, the biopsy parts performed by thoracotomy were sent for immunohistochemical testing. The CD30 and CD15 positive markers distinctive for Reed-Sternberg cells allowed the diagnosis of Hodgkin's lymphoma. PMID:26016055

    The purpose of this preliminary study was to determine the incidence of second malignancies after combined-modality therapy for adults with Hodgkin disease and relate it to the details of initial treatment. We retrospectively studied 286 patients ranging in age from 16 to 88 years with stage I or II Hodgkin disease who were treated between 1980 and 1995 with chemotherapy followed 3 to 4 weeks later by radiotherapy. Patients received a median of three cycles of induction chemotherapy. Mitoxantrone, vincristine, vinblastine, and prednisone was used in 161 cases, mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) in 67 cases, Adriamycin, bleomycin, vinblastine, and dacarbazine in 19 cases, lomustine, vinblastine, procarbazine, and prednisone/doxorubicin, bleomycin, dacarbazine, and lomustine in 18 cases, and other chemotherapeutic regimens in the remaining 21 cases. The median radiotherapy dose was 40 Gy given in 20 daily 2-Gy fractions. Median follow-up of surviving patients was 7.4 years. There were 2,230 person-years of observation. Significantly increased relative risks (RR) were observed for acute myeloid leukemia (RR, 69.3; 95% CI, 14.3-202.6) and melanoma (RR, 7.3; 95% CI, 1.5-21.3). The 5-, 10-, and 15-year actuarial risks of acute myeloid leukemia were 0.8%, 1.3%, and 1.3%, respectively. Patients treated with MOPP had the highest 15-year actuarial risk of leukemia (1.6%). The 5-, 10-, and 15-year actuarial risks of solid tumors were 1.9%, 9.3%, and 16.8%, respectively. Consolidative radiotherapy to both sides of the diaphragm resulted in a trend toward an increased risk of solid tumors relative to radiotherapy to only one side of the diaphragm (p = 0.08). In an effort to reduce the risk of second malignancies, we have stopped using the alkylating agents nitrogen mustard and procarbazine and elective paraaortic and splenic radiotherapy after chemotherapy.

    Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) has traditionally been recognized as having two morphologic patterns, nodular and diffuse, and the current WHO definition of NLPHL requires at least a partial nodular pattern. Variant patterns have not been well documented. We analyzed retrospectively the morphologic and immunophenotypic patterns of NLPHL from 118 patients (total of 137 biopsy samples). Histology plus antibodies directed against CD20, CD3, and CD21 were used to evaluate the immunoarchitecture. We identified six distinct immunoarchitectural patterns in our cases of NLPHL: "classic" (B-cell-rich) nodular, serpiginous/interconnected nodular, nodular with prominent extranodular L&H cells, T-cell-rich nodular, diffuse with a T-cell-rich background (T-cell-rich B-cell lymphoma [TCRBCL]-like), and a (diffuse) B-cell-rich pattern. Small germinal centers within neoplastic nodules were found in approximately 15% of cases, a finding not previously emphasized in NLPHL. Prominent sclerosis was identified in approximately 20% of cases and was frequently seen in recurrent disease. Clinical follow-up was obtained on 56 patients, including 26 patients who had not had recurrence of disease and 30 patients who had recurrence. The follow-up period was 5 months to 16 years (median 2.5 years). The presence of a diffuse (TCRBCL-like) pattern was significantly more common in patients with recurrent disease than those without recurrence. Furthermore, the presence of a diffuse pattern (TCRBCL-like) was shown to be an independent predictor of recurrent disease (P = 0.00324). In addition, there is a tendency for progression to an increasingly more diffuse pattern over time. Analysis of sequential biopsies from patients with recurrent disease suggests that the presence of prominent extranodular L&H cells might represent early evolution to a diffuse (TCRBCL-like) pattern. We also report three patients who presented initially with diffuse large B-cell lymphoma and later developed NLPHL. PMID:14508396

    Classic Hodgkin lymphoma (cHL) has few known modifiable risk factors, and the relationship between diet and cHL risk is unclear. We performed the first investigation of an association between dietary pattern and cHL risk in 435 cHL cases and 563 population-based controls from Massachusetts and Connecticut (1997-2000) who completed baseline diet questionnaires. We identified 4 major dietary patterns ("vegetable," "high meat," "fruit/low-fat dairy," "desserts/sweets") using principal components analysis. We computed multivariable odds ratios and 95% confidence intervals for associations of dietary pattern score (quartiles) with younger-adult (age <50 years), older-adult (age ?50 years), and overall cHL risk. Secondary analyses examined associations by histological subtype and tumor Epstein-Barr virus (EBV) status. A diet high in desserts/sweets was associated with younger-adult (odds ratio(quartile 4 vs. quartile 1) = 1.60, 95% confidence interval: 1.05, 2.45; Ptrend = 0.008) and EBV-negative, younger-adult (odds ratio = 2.11, 95% confidence interval: 1.31, 3.41; Ptrend = 0.007) cHL risk. A high meat diet was associated with older-adult (odds ratio = 3.34, 95% confidence interval: 1.02, 10.91; Ptrend = 0.04) and EBV-negative, older-adult (odds ratio = 4.64, 95% confidence interval: 1.03, 20.86; Ptrend = 0.04) cHL risk. Other dietary patterns were not clearly associated with cHL. We report the first evidence for a role of dietary pattern in cHL etiology. Diets featuring high intake of meat or desserts and sweets may increase cHL risk. PMID:26182945

    The non-Hodgkin lymphoma (NHL) is one of the most common shoulder neoplasms, especially the diffuse large B cell lymphoma (DLBCL). We report a rare case of shoulder pain in a 80-year-old man presenting with a six-month history of continuous severe pain to the right shoulder. Routine laboratory studies were normal. Shoulder MRI showed an in-growing inhomogeneous lesion in the anteromedial aspect of the right humeral head extended within the cortical bone of the humerus (osteolitic lesion), next to the surrounding soft tissues. He also underwent shoulder arthroscopy: the intra-articular involvement of the shoulder was therefore excluded. A percutaneous bone biopsy performed on the same day was diagnostic for lymphoma. Three days later, the patient underwent surgical excision of the mass; a reverse shoulder prosthesis was then implanted (Aequalis reversed prosthesis). The patient started chemiotherapy according with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) regimen, but did not tolerate it because of the sudden onset of herpes zoster. At 9-month follow-up, the patient is doing well, with fair range of motion, due to the delay of rehabilitation, but no shoulder pain and no evidence of local or systemic recurrence. A painful shoulder may be due to lymphoma even in the absence of classical symptoms. In suspected patients, plain radiographs should be followed by magnetic resonance imaging and bone biopsy. Tumor removal and shoulder arthroplasty can be an effective therapy. Given the devastating side effects of adjuvant chemotherapy, we do not recommend it in elderly patients. PMID:24367786

    Hodgkin/Reed-Sternberg lymphoma (HL) is a clonal B-cell-related malignancy. Although many patients with HL can be cured by the current regimen of high-dose multi-agent chemotherapy, the treatment causes high risks of later pathologies including secondary malignancies. This fact highlights the demand to develop rational treatment for HL. Survival and growth of HL cells are largely dependent on their microenvironment. In this study, using the HL cell lines L1236 and KM-H2 as model systems, we investigated the role of IL-4/IL-13 signaling in regulation of drug sensitivity and resistance in HL. We show that specific blocking of IL-4 and IL-13-mediated STAT6 activation by either an IL-4-binding fusion protein APG598 or an IL-4R antagonist APG201 (R121D/Y124D) renders HL cells more prone to apoptotic killing by chemotherapeutic drugs such as Mitomycin C, 5-Fluorouracil, Etopside, Doxorubicin and Paclitaxel. This effect is due to inhibition of STAT6-mediated elevation of expression of the anti-apoptotic Bcl-2 family protein Bcl-xL. Employing ChIP analysis in combination with APG201 or STAT6-specific siRNA we identified a defined STAT6-binding site in the Bcl-xL promoter region from -1967 to -1957 of the transcription start site. Our data demonstrate that the IL-4/IL-13-STAT6-Bcl-xL axis may be an important target for HL treatment. This study also suggests that combination of classical chemotherapeutic drugs with the IL-4/IL-13 antagonists may enhance efficacy and reduce risks of toxicity from high dose of drugs in HL treatment.

    The purpose of this work was to modernize recommendations for evaluation, staging, and response assessment of patients with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL). A workshop was held at the 11th International Conference on Malignant Lymphoma in Lugano, Switzerland, in June 2011, that included leading hematologists, oncologists, radiation oncologists, pathologists, radiologists, and nuclear medicine physicians, representing major international lymphoma clinical trials groups and cancer centers. Clinical and imaging subcommittees presented their conclusions at a subsequent workshop at the 12th International Conference on Malignant Lymphoma, leading to revised criteria for staging and of the International Working Group Guidelines of 2007 for response. As a result, fluorodeoxyglucose (FDG) positron emission tomography (PET)–computed tomography (CT) was formally incorporated into standard staging for FDG-avid lymphomas. A modification of the Ann Arbor descriptive terminology will be used for anatomic distribution of disease extent, but the suffixes A or B for symptoms will only be included for HL. A bone marrow biopsy is no longer indicated for the routine staging of HL and most diffuse large B-cell lymphomas. However, regardless of stage, general practice is to treat patients based on limited (stages I and II, nonbulky) or advanced (stage III or IV) disease, with stage II bulky disease considered as limited or advanced disease based on histology and a number of prognostic factors. PET-CT will be used to assess response in FDG-avid histologies using the 5-point scale. The product of the perpendicular diameters of a single node can be used to identify progressive disease. Routine surveillance scans are discouraged. These recommendations should improve evaluation of patients with lymphoma and enhance the ability to compare outcomes of clinical trials. PMID:25113753

    2016-02-01

    Chinese character structure has often been described as representing a kind of grammar, but the notion of character grammar has hardly been explored. Patterns in character element reduplication are particularly grammar-like, displaying discrete combinatoriality, binarity, phonology-like final prominence, and potentially the need for symbolic rules (X?XX). To test knowledge of these patterns, Chinese readers were asked to judge the acceptability of fake characters varying both in grammaticality (obeying or violating reduplication constraints) and in lexicality (of the reduplicative configurations). While lexical knowledge was important (lexicality improved acceptability and grammatical configurations were accepted more quickly when also lexical), grammatical knowledge was important as well, with grammaticality improving acceptability equally for lexical and nonlexical configurations. Acceptability was also higher for more frequent reduplicative elements, suggesting that the reduplicative configurations were decomposed. Chinese characters present an as-yet untapped resource for exploring fundamental questions about the nature of the human capacity for grammar. PMID:26684059

    Fractional classical mechanics has been introduced and developed as a classical counterpart of the fractional quantum mechanics. Lagrange, Hamilton and Hamilton-Jacobi frameworks have been implemented for the fractional classical mechanics. The Lagrangian of fractional classical mechanics has been introduced, and equation of motion has been obtained. Fractional oscillator model has been launched and solved in 1D case. A new equation for the period of oscillations of fractional classical oscillator has been found. The interplay between the energy dependency of the period of classical oscillations and the non-equidistant distribution of the energy levels for fractional quantum oscillator has been discussed. We discuss as well, the relationships between new equations of fractional classical mechanics and the well-known fundamental equations of classical mechanics.

    Purpose: To determine the diagnostic performance of three-dimensional (3D) texture analysis (TA) of contrast-enhanced computed tomography (CE-CT) images for treatment response assessment in patients with Hodgkin lymphoma (HL), compared with F-18-fludeoxyglucose (FDG) positron emission tomography/CT. Methods: 3D TA of 48 lymph nodes in 29 patients was performed on venous-phase CE-CT images before and after chemotherapy. All lymph nodes showed pathologically elevated FDG uptake at baseline. A stepwise logistic regression with forward selection was performed to identify classic CT parameters and texture features (TF) that enable the separation of complete response (CR) and persistent disease. Results: The TF fraction of image in runs, calculated for the 45° direction, was able to correctly identify CR with an accuracy of 75%, a sensitivity of 79.3%, and a specificity of 68.4%. Classical CT features achieved an accuracy of 75%, a sensitivity of 86.2%, and a specificity of 57.9%, whereas the combination of TF and CT imaging achieved an accuracy of 83.3%, a sensitivity of 86.2%, and a specificity of 78.9%. Conclusions: 3D TA of CE-CT images is potentially useful to identify nodal residual disease in HL, with a performance comparable to that of classical CT parameters. Best results are achieved when TA and classical CT features are combined.

    Tumor cells with tumorigenic potential are limited to a small cell population known as cancer stem cells (CSCs). CSCs yield both CSCs and non-CSCs, whereas non-CSCs do not yield CSCs. CSCs have not been identified in any malignant lymphomas. Hodgkin lymphoma (HL) is a mostly B-cell neoplasm that can be diagnosed by the presence of multinucleated (Reed-Sternberg; RS) cells admixed with Hodgkin cells with distinct nucleoli and various inflammatory cells. Here, the tumorigenic potential of cells with a single nucleus (S) and cells with multiple nuclei (M), which may be equivalent to Hodgkin and RS cells, respectively, was examined in HL cell lines L1236 and L428. Cultures of single S cells yielded both S and M cells, whereas M cell cultures yielded only M cells. When either cultured in methylcellulose or inoculated into NOD/SCID mice, the colony number and tumor size were both larger in S than in M cells. Concentrations of intracellular reactive oxygen species (ROS) were at low levels in a portion of S cells that abundantly expressed FoxO3a, a transcription factor that regulates ROS-degrading enzymes. In clinical samples of HL, FoxO3a was expressed in mononuclear Hodgkin cells but not in multinucleated RS cells. These findings suggest that smaller cells or Hodgkin cells that show low-ROS concentrations and high FoxO3a expression levels might be candidates for HL CSCs. PMID:20952592

    Cystic odontoma is a rare entity, which is characterized by the association of a cyst with complex/compound odontoma. The aim of this study was to report the case of a 5-year-old male patient diagnosed previously with Hodgkin's lymphoma and treated successfully with chemotherapy and radiotherapy, who developed a mandibular odontogenic lesion. Physical examination revealed a swelling on the right side of the mandible. Radiographically, a well-defined radiolucent area surrounded by radiopaque material was observed. An incisional biopsy was performed and microscopic analysis showed a cystic lesion consisting of an atrophic epithelium comprising 2-3 cell layers and the absence of inflammation in the cystic capsule. The cyst was decompressed and the lesion was removed after 3 months of follow-up. Microscopic analysis of the surgical specimen showed a cystic hyperplastic epithelium surrounded by an intense chronic inflammatory cell infiltrate, which was in close contact with mineralized tissue resembling dentin and cementum. The final diagnosis was cystic odontoma. Since chemotherapy can affect the growth and development of infant teeth, a relationship between chemotherapy-associated adverse events and cystic odontoma is suggested in the present case.

    Thyroid function was measured in 119 children, 16 years of age or less, after radiotherapy (XRT) for Hodgkin's disease. Thyroid abnormalities developed in 4 of 24 children (17%) who received 2600 rad or less, and in 74 of 95 children (78%) who received greater than 2600 rad to the cervical area, including the thyroid. The abnormality in all but three (one with hyperthyroidism and two with thyroid nodules) included the development of elevated levels of thyroid stimulating hormone (TSH). Age, sex, and administration of chemotherapy were not significant factors in the development of thyroid dysfunction. All children had lymphangiograms (LAG) and no time relationship was noted between thyroid dysfunction and LAG-XRT interval. The mean interval from radiotherapy to documented thyroid dysfunction was 18 months in the low-dose group and 31 months in the high-dose group, with most patients becoming abnormal within 3 to 5 years. Of interest was a spontaneous return of TSH to within normal limits in 20 children and substantial improvement in another 7. This study confirms the occurrence of dose-related occult hypothyroidism in children following external irradiation of the neck.

    The generation of spikes by neurons is energetically a costly process and the evaluation of the metabolic energy required to maintain the signalling activity of neurons a challenge of practical interest. Neuron models are frequently used to represent the dynamics of real neurons but hardly ever to evaluate the electrochemical energy required to maintain that dynamics. This paper discusses the interpretation of a Hodgkin-Huxley circuit as an energy model for real biological neurons and uses it to evaluate the consumption of metabolic energy in the transmission of information between neurons coupled by electrical synapses, i.e. gap junctions. We show that for a single postsynaptic neuron maximum energy efficiency, measured in bits of mutual information per ATP molecule consumed, requires maximum energy consumption. On the contrary, for groups of parallel postsynaptic neurons we determine values of the synaptic conductance at which the energy efficiency of the transmission presents clear maxima at relatively very low values of metabolic energy consumption. Contrary to what it could be expected best performance occurs at low energy cost.

    Recent studies have reported that regions of homozygosity (ROH) in the genome are detectable in outbred populations and can be associated with an increased risk of malignancy. To examine whether homozygosity is associated with an increased risk of developing Hodgkin lymphoma (HL) we analysed 589 HL cases and 5,199 controls genotyped for 484,072 tag single nucleotide polymorphisms (SNPs). Across the genome the cumulative distribution of ROH was not significantly different between cases and controls. Seven ROH at 4q22.3, 4q32.2, 7p12.3–14.1, 7p22.2, 10p11.22–23, 19q13.12-2 and 19p13.2 were associated with HL risk at P?

    In Hodgkin lymphoma (HL) we recently identified deregulated expression of homeobox genes MSX1 and OTX2 which are physiologically involved in development of the embryonal neural plate border region. Here, we examined in HL homeobox gene SIX1 an additional regulator of this embryonal region mediating differentiation of placodal precursors. SIX1 was aberrantly activated in 12 % of HL patient samples in silico, indicating a pathological role in a subset of this B-cell malignancy. In addition, SIX1 expression was detected in HL cell lines which were used as models to reveal upstream factors and target genes of this basic developmental regulator. We detected increased copy numbers of the SIX1 locus at chromosome 14q23 correlating with enhanced expression while chromosomal translocations were absent. Moreover, comparative expression profiling data and pertinent gene modulation experiments indicated that the WNT-signalling pathway and transcription factor MEF2C regulate SIX1 expression. Genes encoding the transcription factors GATA2, GATA3, MSX1 and SPIB - all basic lymphoid regulators - were identified as targets of SIX1 in HL. In addition, cofactors EYA1 and TLE4, respectively, contrastingly mediated activation and suppression of SIX1 target gene expression. Thus, the protein domain interfaces may represent therapeutic targets in SIX1-positive HL subsets. Collectively, our data reveal a gene regulatory network with SIX1 centrally deregulating lymphoid differentiation and support concordance of lymphopoiesis/lymphomagenesis and developmental processes in the neural plate border region.

    2015-12-01

    Hodgkin lymphoma (HL) incidence varies with migration and nativity, suggesting an influence of acculturation on risk. In population-based California data including 1483 Hispanic and 348 Asian/Pacific Islander (API) HL cases, we examined HL rates in residential neighborhoods classified by ethnic enclave status (measuring degree of acculturation) and socioeconomic status (SES). Rates were inversely associated with enclave intensity, although associations varied by gender and race. In females, the enclave effect was stronger in low-SES settings, but rates were higher in less-ethnic/high-SES than more-ethnic/low-SES neighborhoods - diminishing enclave intensity affected rates more than higher SES. In Hispanics, associations were modest, and only females experienced SES modification of rates; in APIs, the enclave effect was much stronger. Thus, acculturation measured by residence in ethnic enclaves affects HL rates independently of neighborhood SES but in complex patterns. Living in less-ethnic neighborhoods may increase HL rates by facilitating social isolation and other gender-specific exposures implicated in risk. PMID:25899402

    Hodgkin lymphoma (HL) is a highly curable form of childhood cancer, with estimated 5 year survival rates exceeding 98%. However, the establishment of a "standard of care" approach to its management is complicated by the recognition that long-term overall survival declines in part from delayed effects of therapy and that there continue to be subgroups of patients at risk for relapse for which prognostic criteria cannot adequately define. This challenge has resulted in the development of various strategies aimed at identifying the optimal balance between maintaining overall survival and avoidance of long-term morbidity of therapy, often representing strategies quite different from those used for adults with HL. More precise risk stratification and methods for assessing the chemosensitivity of HL through imaging studies and biomarkers are in evolution. Recent advances in the understanding of the biology of HL have led to the introduction of targeted therapies in both the frontline and relapsed settings. However, significant barriers exist in the development of new combination therapies, necessitating collaborative studies across pediatric HL research consortia and in conjunction with adult groups for the adolescent and young adult (AYA) population with HL.

    Purpose: To compare the health practice of Hodgkin's lymphoma (HL) survivors and their siblings, and to assess the impact of socioeconomic status and disease history on health practice of HL survivors. Methods and Materials: We conducted a questionnaire study on long-term HL survivors and their siblings on health care utilization, health habits, and screening behavior. Results: A total of 511 HL survivors (response rate of 50%, including survivors lost to contact) and 224 siblings (response rate, 58%) participated. Median time from HL diagnosis was 15 years. Significantly more survivors than siblings had a physical examination in the past year (63% vs. 49%, p = 0.0001). Male survivors were significantly more likely than siblings to perform monthly self-testicular examinations (19% vs. 9%, p = 0.02). Among survivors, higher household income (p = 0.01) independently predicted for having had a physical examination in the past year. Lower educational level (p = 0.0004) and history of relapsed HL (p = 0.03) were independent predictors for smoking, moderate/heavy alcohol use, and/or physical inactivity. Conclusions: Compared with siblings, long-term HL survivors have a higher level of health care utilization and better screening practice. Survivors from lower socioeconomic background had lower adherence to routine health care and greater report of unhealthy habits. Survivors with history of relapsed HL were also more likely to engage in unhealthy habits.

    The incidence of Non-Hodgkin's lymphomas (NHL) is rising worldwide and if not adequately treated carries a high mortality rate. The pattern and frequency of NHL vary in different populations and geographical regions. It has considerable biologic and clinical heterogeneity and a definitive diagnosis can be made only after histopathogical examination. The histology and the extent of the lymphoma are the major determinants of optimal therapeutic regimen and treatment outcome. Additionally, the overall treatment strategies should be tailored according to medical status and preference of the patient. A holistic approach provided by a multi-disciplinary team of health care professionals is the cornerstone of ensuring successful treatment outcome. Importantly, therapy should be expedited and where possible performed in experienced centers. Patients achieving remission would require long-term monitoring for disease recurrence and late effects of cytotoxic chemotherapy and radiotherapy. Hence, clinicians should have a fundamental understanding in the biology and the principles of treatment of NHL. This review provides an evidence-based and systematic approach in designing therapeutic strategies for individual patients with newly diagnosed and relapsed NHL focusing on the common types of NHL with particular reference to the current practice within the local settings. The role of standard and novel therapeutic modalities in treatment will be summarized. PMID:20954564

    Background. Although patients with Hodgkin's lymphoma (HL) achieve prolonged survival, long-term complications are a major cause of morbidity and mortality among long-term survivors of HL. Methods. We retrospectively evaluated long-term complications in 336 HL survivors treated between January 1990 and January 2006 at the Department of Medical Oncology of the Hacettepe University Institute of Oncology who were >16 years old at presentation. All patients were regularly followed up every 3 months for the first 2 years after complete response, biannually for 3 years, and annually after 5 years. Results. Median follow-up was 8.5 years. The mean age (±SD) of the patients at the time of diagnosis was 35.7 ± 13.1 years. The male to female ratio was 61%/39%. During follow-up, 29 second malignancies (8.6%) were diagnosed in 28 patients with HL; 22 were solid tumors and 7 were hematological malignancies. Forty-seven (14.0%) of all patients with HL were found to have thyroid abnormalities. During follow-up, 54 (16.1%) patients developed cardiovascular complications. Overall, 29 (8.6%) patients developed late pulmonary toxicities. The cumulative number of chronic viral infections was 13 (3.9%). Conclusions. Long-term survivors of HL need to be properly followed up not only for disease control but also for evaluation of possible late morbidities to minimize the consequences. PMID:23235755

  16. Fibroblast growth factor-2 (FGF2) and syndecan-1 (SDC1) are potential biomarkers for putative circulating CD15+/CD30+ cells in poor outcome Hodgkin lymphoma patients

    PubMed Central

    2013-01-01

    Background High risk, unfavorable classical Hodgkin lymphoma (cHL) includes those patients with primary refractory or early relapse, and progressive disease. To improve the availability of biomarkers for this group of patients, we investigated both tumor biopsies and peripheral blood leukocytes (PBL) of untreated (chemo-naïve, CN) Nodular Sclerosis Classic Hodgkin Lymphoma (NS-cHL) patients for consistent biomarkers that can predict the outcome prior to frontline treatment. Methods and materials Bioinformatics data mining was used to generate 151 candidate biomarkers, which were screened against a library of 10 HL cell lines. Expression of FGF2 and SDC1 by CD30+ cells from HL patient samples representing good and poor outcomes were analyzed by qRT-PCR, immunohistochemical (IHC), and immunofluorescence analyses. Results To identify predictive HL-specific biomarkers, potential marker genes selected using bioinformatics approaches were screened against HL cell lines and HL patient samples. Fibroblast Growth Factor-2 (FGF2) and Syndecan-1 (SDC1) were overexpressed in all HL cell lines, and the overexpression was HL-specific when compared to 116 non-Hodgkin lymphoma tissues. In the analysis of stratified NS-cHL patient samples, expression of FGF2 and SDC1 were 245 fold and 91 fold higher, respectively, in the poor outcome (PO) group than in the good outcome (GO) group. The PO group exhibited higher expression of the HL marker CD30, the macrophage marker CD68, and metastatic markers TGF?1 and MMP9 compared to the GO group. This expression signature was confirmed by qualitative immunohistochemical and immunofluorescent data. A Kaplan-Meier analysis indicated that samples in which the CD30+ cells carried an FGF2+/SDC1+ immunophenotype showed shortened survival. Analysis of chemo-naive HL blood samples suggested that in the PO group a subset of CD30+ HL cells had entered the circulation. These cells significantly overexpressed FGF2 and SDC1 compared to the GO group. The PO group showed significant down-regulation of markers for monocytes, T-cells, and B-cells. These expression signatures were eliminated in heavily pretreated patients. Conclusion The results suggest that small subsets of circulating CD30+/CD15+ cells expressing FGF2 and SDC1 represent biomarkers that identify NS-cHL patients who will experience a poor outcome (primary refractory and early relapsing).

    We construct the equation of a state of the classical QGP valid for all values of Gamma=V/K, the ratio of the mean Coulomb to kinetic energy. By enforcing the Gibbs relations, we derive the pertinent pressure and entropy densities for all Gamma. For the case of an SU(2) classical gluonic plasma our results compare well with lattice simulations. We show that the strongly coupled component of the classical QGP contributes significantly to the bulk thermodynamics across T_c.

    2015-01-01

    ABSTRACT Background: Despite multiple published studies reporting result of salvage regimens for relapsed and refractory Hodgkin's lymphoma, there are no comparisons of different combinations. Patients and methods: A Total of 44 patients identified with refractory or relapsed Hodgkin's Lymphoma were considered eligible for this study. The Patients were randomly divided into two groups of 22, one of which were treated with GDP regimen (gemcitabine, dexamethasone and cisplatin) and the other with EHSAP regimen (etoposide, methyl prednisolone, cisplatin and cytarabine) in a prospective manner. The results of each group were compared. Results: There were 27.3% complete response, 31.8% more than 50% response, and 40.9% no response with GDP. ESHAP results were 29.5%, 24% and 45.5%, respectively. Conclusion: There is no significant difference in response rate between GDP and ESHAP regimens as salvage chemotherapy in refractory or relapsed Hodgkin's Lymphoma. PMID:25802695

    Objective To report two cases of concomitant choroidal melanoma and intraocular non-Hodgkin lymphoma in two patients. Design Case report. Participants Two patients with yellow creamy infiltrates in fundo. Intervention Both patients had a complete ophthalmologic evaluation and histology was obtained after enucleation of the affected eye. Main Outcome Measures Histology findings of the enucleated eyes. Results One patient showed a choroidal melanoma with a primary non-Hodgkin lymphoma located solely in the affected eye. The other patient showed a systemic non-Hodgkin lymphoma with ocular manifestations concomitant with a choroidal melanoma. Conclusions In the presence of yellow creamy infiltrates one should include a choroidal lymphoma in the differential diagnosis even if there is another clear pathologic condition. Furthermore in those cases systemic disease should be excluded. PMID:22807909

    Quantum discord is the quantitative difference between two alternative expressions for bipartite mutual information, given respectively in terms of two distinct definitions for the conditional entropy. By constructing a stochastic model of shared states, classical discord can be similarly defined, quantifying the presence of some stochasticity in the measurement process. Therefore, discord can generally be understood as a quantification of the system's state disturbance due to local measurements, be it quantum or classical. We establish an operational meaning of classical discord in the context of state merging with noisy measurement and thereby show the quantum-classical separation in terms of a negative conditional entropy.

  2. Dynamics from Seconds to Hours in Hodgkin-Huxley Model with Time-Dependent Ion Concentrations and Buffer Reservoirs

    Hübel, Niklas; Dahlem, Markus A.

    2014-01-01

    The classical Hodgkin-Huxley (HH) model neglects the time-dependence of ion concentrations in spiking dynamics. The dynamics is therefore limited to a time scale of milliseconds, which is determined by the membrane capacitance multiplied by the resistance of the ion channels, and by the gating time constants. We study slow dynamics in an extended HH framework that includes time-dependent ion concentrations, pumps, and buffers. Fluxes across the neuronal membrane change intra- and extracellular ion concentrations, whereby the latter can also change through contact to reservoirs in the surroundings. Ion gain and loss of the system is identified as a bifurcation parameter whose essential importance was not realized in earlier studies. Our systematic study of the bifurcation structure and thus the phase space structure helps to understand activation and inhibition of a new excitability in ion homeostasis which emerges in such extended models. Also modulatory mechanisms that regulate the spiking rate can be explained by bifurcations. The dynamics on three distinct slow times scales is determined by the cell volume-to-surface-area ratio and the membrane permeability (seconds), the buffer time constants (tens of seconds), and the slower backward buffering (minutes to hours). The modulatory dynamics and the newly emerging excitable dynamics corresponds to pathological conditions observed in epileptiform burst activity, and spreading depression in migraine aura and stroke, respectively.

    HLA genotyping and genome wide association studies provide strong evidence for associations between Human Leukocyte Antigen (HLA) alleles and classical Hodgkin lymphoma (cHL). Analysis of these associations is complicated by the extensive linkage disequilibrium within the major histocompatibility region and recent data suggesting that associations with EBV-positive and EBV-negative cHL are largely distinct. To distinguish independent and therefore potentially causal associations from associations confounded by linkage disequilibrium, we applied a variable selection regression modeling procedure to directly typed HLA class I and II genes and selected SNPs from EBV-stratified patient subgroups. In final models, HLA-A*01:01 and B*37:01 were associated with an increased risk of EBV-positive cHL whereas DRB1*15:01 and DPB1*01:01 were associated with decreased risk. Effects were independent of a prior history of infectious mononucleosis. For EBV-negative cHL the class II SNP rs6903608 remained the strongest predictor of disease risk after adjusting for the effects of common HLA alleles. Associations with "all cHL" and differences by case EBV status reflected the subgroup analysis. In conclusion, this study extends previous findings by identifying novel HLA associations with EBV-stratified subgroups of cHL, highlighting those alleles likely to be biologically relevant and strengthening evidence implicating genetic variation associated with the SNP rs6903608.

    The prevalence of myopia in Chinese children has been rising each year. Research has shown that orthokeratology is a good method for controlling the progression of myopia. In this article, we review the current prevalence of myopia, the development and management of orthokeratology, and the myopia control methods used in China. A physical and health survey release indicated that the ratio of poor vision in every range of ages is still high in China. During the past 17 years, Chinese doctors have developed a standard fitting procedure and medical management of orthokeratology patients. This article also reviews the clinical studies in China for Ortho-K lenses, such as myopia control, effects and safety, corneal change, and lens design and fitting. Finally, we review the development of the International Academy of Orthokeratology Asia in China. PMID:26704137

    TNFAIP2 is a protein upregulated in response to TNF signaling but its cellular expression and function in normal and neoplastic tissues remains largely unknown. Here we use standard immunohistochemical techniques to demonstrate that TNFAIP2 is normally expressed by follicular dendritic cells, interdigitating dendritic cells, and macrophages but not by lymphoid cells in secondary lymphoid tissues. Consistent with this expression pattern, we found strong TNFAIP2 staining of tumor cells in 4/4 cases (100%) of follicular dendritic cell sarcoma and in 3/3 cases (100%) of histiocytic sarcoma. Although TNFAIP2 is not expressed by the small and intermediate-size neoplastic B-cells comprising follicular lymphoma, small lymphocytic lymphoma, mantle cell lymphoma, or marginal zone lymphoma, we observed strong TNFAIP2 staining of the large, neoplastic cells, in 31/31 cases (100%) of classical Hodgkin lymphoma, 12/12 cases (100%) of nodular lymphocyte predominant Hodgkin lymphoma, and 27/31 cases (87%) of primary mediastinal (thymic) large B cell lymphoma. In contrast, TNFAIP2 was expressed by the malignant cells in only 2/45 cases (4%) of diffuse large B cell lymphoma, not otherwise specified, 2/18 cases (11%) of Burkitt lymphoma, and 1/19 cases (5%) of anaplastic large cell lymphoma. Further analysis indicates that TNFAIP2, as a single diagnostic marker, is more sensitive (sensitivity= 87%) and specific (specificity= 96%) than TRAF1, nuclear cRel, or CD23 for distinguishing the malignant B-cells of primary mediastinal (thymic) large B cell lymphoma from those of its morphologic and immunophenotypic mimic, diffuse large B cell lymphoma, not otherwise specified. Thus, TNFAIP2 may serve as a useful new marker of dendritic and histiocytic sarcomas whose aberrant expression in the malignant cells of classical Hodgkin lymphoma and primary mediastinal (thymic) large B cell lymphoma serves to distinguish these tumors from other large cell lymphomas in routine clinical practice.

  10. Scope processing in Chinese.

    The standard view maintains that quantifier scope interpretation results from an interaction between different modules: the syntax, the semantics as well as the pragmatics. Thus, by examining the mechanism of quantifier scope interpretation, we will certainly gain some insight into how these different modules interact with one another. To observe it, two experiments, an offline judgment task and an eye-tracking experiment, were conducted to investigate the interpretation of doubly quantified sentences in Chinese, like Mei-ge qiangdao dou qiang-le yi-ge yinhang (Every robber robbed a bank). According to current literature, doubly quantified sentences in Chinese like the above are unambiguous, which can only be interpreted as "for every robber x, there is a bank y, such that x robbed y"(surface scope reading), contrary to their ambiguous English counterparts, which also allow the interpretation that "there is a bank y, such that for every robber x, x robbed y"(inverse scope reading). Specifically, three questions were examined, that is, (i) What is the initial reading of doubly quantified sentences in Chinese? (ii) Whether inverse scope interpretation can be available if appropriate contexts are provided? (iii) What are the processing time courses engaged in quantifier scope interpretation? The results showed that (i) Initially, the language processor computes the surface scope representation and the inverse scope representation in parallel, thus, doubly quantified sentences in Chinese are ambiguous; (ii) The discourse information is not employed in initial processing of relative scope, it serves to evaluate the two representations in reanalysis; (iii) The lexical information of verbs affects their scope-taking patterns. We suggest that these findings provide evidence for the Modular Model, one of the major contenders in the literature on sentence processing. PMID:18521750

    According to the 4th National Nutrition and Health Survey in 2002, the prevalence of hypertension in China was 18.8%. Although there are no recent updated nationwide data, it is believed that the prevalence of hypertension has increased substantially in the past decade up to more than 200 million hypertensive patients in the populous country of China. To fight against the growing risk of hypertension, three Chinese hypertension guidelines were compiled in the past two decades, in 1999, 2005, and 2011. The current guidance document for the management of hypertension was named ‘2010 Chinese hypertension guideline’, but it was actually published in 2011. In this guideline, all five classes of antihypertensive drugs were recommended as possible initial and maintenance therapy. The goal of treatment was a systolic/diastolic blood pressure below 140/90 mm Hg in general, 130/80 mm Hg in various groups of high-risk patients, and 150/90 mm Hg in the elderly (?65 years). With the recent publication of several national and international hypertension guidelines, the Chinese guideline is now under discussion for updating.

    The SPS product, Classic-Ada, is a software tool that supports object-oriented Ada programming with powerful inheritance and dynamic binding. Object Oriented Design (OOD) is an easy, natural development paradigm, but it is not supported by Ada. Following the DOD Ada mandate, SPS developed Classic-Ada to provide a tool which supports OOD and implements code in Ada. It consists of a design language, a code generator and a toolset. As a design language, Classic-Ada supports the object-oriented principles of information hiding, data abstraction, dynamic binding, and inheritance. It also supports natural reuse and incremental development through inheritance, code factoring, and Ada, Classic-Ada, dynamic binding and static binding in the same program. Only nine new constructs were added to Ada to provide object-oriented design capabilities. The Classic-Ada code generator translates user application code into fully compliant, ready-to-run, standard Ada. The Classic-Ada toolset is fully supported by SPS and consists of an object generator, a builder, a dictionary manager, and a reporter. Demonstrations of Classic-Ada and the Classic-Ada Browser were given at the workshop.

    Purpose Treatment-related stomach cancer is an important cause of morbidity and mortality among the growing number of Hodgkin lymphoma (HL) survivors, but risks associated with specific HL treatments are unclear. Patients and Methods We conducted an international case-control study of stomach cancer nested in a cohort of 19,882 HL survivors diagnosed from 1953 to 2003, including 89 cases and 190 matched controls. For each patient, we quantified cumulative doses of specific alkylating agents (AAs) and reconstructed radiation dose to the stomach tumor location. Results Stomach cancer risk increased with increasing radiation dose to the stomach (Ptrend < .001) and with increasing number of AA-containing chemotherapy cycles (Ptrend = .02). Patients who received both radiation to the stomach ? 25 Gy and high-dose procarbazine (? 5,600 mg/m2) had strikingly elevated stomach cancer risk (25 cases, two controls; odds ratio [OR], 77.5; 95% CI, 14.7 to 1452) compared with those who received radiation < 25 Gy and procarbazine < 5,600 mg/m2 (Pinteraction < .001). Risk was also elevated (OR, 2.8; 95% CI, 1.3 to 6.4) among patients who received radiation to the stomach ? 25 Gy but procarbazine < 5,600 mg/m2; however, no procarbazine-related risk was evident with radiation < 25 Gy. Treatment with dacarbazine also increased stomach cancer risk (12 cases, nine controls; OR, 8.8; 95% CI, 2.1 to 46.6), after adjustment for radiation and procarbazine doses. Conclusion Patients with HL who received subdiaphragmatic radiotherapy had dose-dependent increased risk of stomach cancer, with marked risks for patients who also received chemotherapy containing high-dose procarbazine. For current patients, risks and benefits of exposure to both procarbazine and subdiaphragmatic radiotherapy should be weighed carefully. For patients treated previously, GI symptoms should be evaluated promptly. PMID:23980092

    Background: Hodgkin lymphoma (HL) survivors are at increased risk for developing valvular heart disease (VHD). We evaluated the determinants of the risk and the radiation dose-response. Methods: A case-control study was nested in a cohort of 1852 five-year HL survivors diagnosed at ages 15 to 41 years and treated between 1965 and 1995. Case patients had VHD of at least moderate severity as their first cardiovascular diagnosis following HL treatment. Control patients were matched to case patients for age, gender, and HL diagnosis date. Treatment and follow-up data were abstracted from medical records. Radiation doses to heart valves were estimated by reconstruction of individual treatments on representative computed tomography datasets. All statistical tests were two-sided. Results: Eighty-nine case patients with VHD were identified (66 severe or life-threatening) and 200 control patients. Aortic (n = 63) and mitral valves (n = 42) were most frequently affected. Risks increased more than linearly with radiation dose. For doses to the affected valve(s) of less than or equal to 30, 31–35, 36–40, and more than 40 Gy, VHD rates increased by factors of 1.4, 3.1, 5.4, and 11.8, respectively (P trend < .001). Approximate 30-year cumulative risks were 3.0%, 6.4%, 9.3%, and 12.4% for the same dose categories. VHD rate increased with splenectomy by a factor of 2.3 (P = .02). Conclusions: Radiation dose to the heart valves can increase the risk for clinically significant VHD, especially at doses above 30 Gy. However, for patients with mediastinal involvement treated today with 20 or 30 Gy, the 30-year risk will be increased by only about 1.4%. These findings may be useful for patients and doctors both before treatment and during follow-up. PMID:25713164

  16. Lymphocyte predominance Hodgkin's disease: the use of bcl-6 and CD57 in diagnosis and differential diagnosis.

    Distinction of lymphocyte predominance Hodgkin's disease (LPHD) from other forms of lymphoma often requires immunohistochemistry (IHC). Most previously published recommended panels include markers to define the large neoplastic cells (for example, CD20, J chain, CD45) as well as the non-neoplastic background cells (CD21, CD45RO, CD57, TiA 1). In the present study we examine the practical use of a double IHC method designed to look simultaneously at two germinal center specific cell types: bcl6+ cells and [bc16+, CD57+] co-positive cells. All 10 nodular LPHD had bcl6+ large cells and numerous CD57+ small background cells, including [bcl6+CD57+] cells in rosettes. One case of LPHD with large cell transformation contained numerous bcl6+ large cells both singly (in areas of typical LPHD) and in sheets (in foci of large cell transformation), many CD57+ small cells but few [bcl6+CD57+] co-positive cells and no rosettes. In none of the five cases of florid progressive transformation of germinal centers were true rosettes seen, although all contained variable numbers of bcl6+ large cells and CD57+ cells. Lymphocyte-rich classic Hodgkin's disease LRCHD cases were notable for bcl6 reactivity in Reed-Sternberg cells in all cases, numerous background small bcl6+ lymphocytes, and rare CD57+ cells. Two phenotypic profiles were associated with the 10 cases of T cell-rich B cell large cell lymphoma (TCRBCL). In the first, group "A," six of six cases had bc16- large cells and few CD57+ small cells, and none had significant numbers of [bcl6+, CD57+] co-positive cells. In the second, group "B," four of four cases had bcl6+ large cells with numerous CD57+ and [bcl6+, CD57+] co-positive cells. These findings not only show that LPHD can be distinguished from its morphologic mimics through identification of specific germinal center cell types, but also identifies a second group of TCRBCL (group "B") whose phenotype suggests it might be an architectural variant of nodular LPHD.

    Objective To study the main clinical and histopathological features of 12 patients with Hodgkin’s lymphoma (HL) diagnosed primarily from bone marrow (BM) involvement. Methods We included 12 acquired immunodeficiency syndrome (AIDS) patients with HL assisted in the F. J. Muñiz Infectious Diseases Hospital since January 2002 to December 2013. The diagnosis of HL with primary BM involvement in patients was confirmed by clinical, histopathological, and immunohistochemical findings. Results All patients presented “B” symptoms and pancytopenia. All of them had stage IV neoplasm disease because of BM infiltration. The median of CD4+ T-cell counts was 114 cells/?L, and mixed cellularity (MC) was the most frequent histopathological subtype of 92% cases. Conclusion When other causes are excluded, BM biopsy should be performed in AIDS patients with “B” symptoms and pancytopenia to evaluate BM infiltration by atypical lymphocytes. PMID:25859410

    MOPP-chemistry includes potent mutagens which induce chromosomal abnormalities in human somatic and rodent germ cells. Sperm samples five pre- and four rodent germ cells. Sperm samples (five pre- and four post-treatment) from 8 Hodgkin`s patients were analyzed using fluorescence in situ hybridization (FISH) to detect 3 categories of chromosomal defects in sperm: (1) terminal duplications of deletions in chr. 1p, (2) aneuploidy involving chr. 1 or 8, and (3) diploidy. In 3 pre-treatment and 2 post-treatment samples, each from a different donor, the levels of chromosomal damage were comparable to those of healthy controls. For one patient significantly higher proportions of sperm carrying structural chromosome aberrations were detected in a 15 years post-treatment sample, compared to his pre-treatment sample and pre-treatment samples of other patients. This patient also showed significantly elevated levels of hyperploid and diploid sperm in both his pre- and post-treatment samples. Elevated levels of diploid sperm were also observed in a pre-treatment sample of a second patient. In a 23 years post-treatment sample of another patient the fraction of sperm carrying chromosome aberrations was also significantly higher than in pre-treatment samples. To conclude, elevated frequencies of sperm with structural chromosome damage were observed in at least one patient, suggesting clonal outgrowth of chromosomal aberrant stem cells due to MOPP treatment. Although MOPP does not seem to increase numerical aberrations in sperm significant inter-individual differences were present among the Hodgkin`s patient.

    Acoustic characteristics of classical opera singing differ considerably between the Western and the Chinese cultures. Singers in the classical Peking opera tradition specialize on one out of a limited number of standard roles. Audio and electroglottograph signals were recorded for four performers of the Old Man role and three performers of the Colorful Face role. Recordings were made of the singers' speech and when they sang recitatives and songs from their roles. Sound pressure level, fundamental frequency, and spectrum characteristics were analyzed. Histograms showing the distribution of fundamental frequency showed marked peaks for the songs, suggesting a scale tone structure. Some of the intervals between these peaks were similar to those used in Western music. Vibrato rate was about 3.5Hz, that is, considerably slower than in Western classical singing. Spectra of vibrato-free tones contained unbroken series of harmonic partials sometimes reaching up to 17 000Hz. Long-term-average spectrum (LTAS) curves showed no trace of a singer's formant cluster. However, the Colorful Face role singers' LTAS showed a marked peak near 3300Hz, somewhat similar to that found in Western pop music singers. The mean LTAS spectrum slope between 700 and 6000Hz decreased by about 0.2dB/octave per dB of equivalent sound level. PMID:21621380

    Cryostat sections from lymph nodes of 47 Hodgkin disease patients were examined by immunohistology for the Epstein-Barr virus (EBV)-encoded latent membrane protein (LMP), nuclear antigen 2, and late viral glycoprotein gp350/250. A distinct LMP-specific membrane and cytoplasmic staining was detected exclusively in Hodgkin and Reed-Sternberg cells in 18 patients (38%); EBV nuclear antigen 2 and gp350/250 immunoreactivity was absent in all instances. Thirty-two of 47 (68%) cases contained EBV-specific DNA sequences as detected by PCR, all LMP-positive cases being in this category. Our results confirm previous studies establishing the presence of EBV genomes in Hodgkin and Reed-Sternberg cells by demonstrating expression of an EBV-encoded protein in the tumor-cell population. The finding of LMP expression in the absence of EBV nuclear antigen 2 suggests a pattern of EBV gene expression different from that of B-lymphoblastoid cell lines and Burkitt lymphoma, whereas this finding shows similarities with that seen in undifferentiated nasopharyngeal carcinoma. Because the LMP gene has transforming potential, our findings support the concept of a pathoetiological role of EBV in many cases of Hodgkin disease. Images PMID:1647016

  6. Distribution of abdominal and pelvic Hodgkin disease: implications for CT scanning

    Computed tomography of the abdomen and pelvis is frequently performed for the staging of abdominal and pelvic lymphoma. Certain limited CT protocols have been nearly as accurate as more complete examinations at defining the extent of lymphadenopathy and the response to therapy, with the advantages of decreased scanning time and patient radiation dose. The authors reviewed abdominal and pelvic CT scans and reports of 58 patients with Hodgkin disease to determine whether the entire abdomen and pelvis must always be scanned in such patients. Pelvic adenopathy without concurrent abdominal adenopathy was present in only one of 58 patients, and that patient presented clinically with inguinal adenopathy. These findings are supported by larger pathologic studies showing that Hodgkin disease always spreads contiguously. Patients with Hodgkin disease presenting above the diaphragm should undergo abdominal CT for staging; if the abdomen is normal, the pelvis need not be scanned. For Hodgkin patients with clinical or CT evidence of disease below the diaphragm, both abdomen and pelvis should be scanned.

    Infections were examined as possible risk factors for non-Hodgkin lymphoma in a population-based case-control study in New South Wales and the Australian Capital Territory, Australia. Incident cases (n = 694) had no history of HIV infection or transplantation. Controls (n = 694) were randomly selected from electoral rolls and frequency matched to cases by age, sex, and area of residence. A postal questionnaire and telephone interview measured history of specific infections, occupational exposures, and behavioral and other risk factors for infection. Blood samples were tested for antibodies to human T-lymphotrophic virus type I and hepatitis C virus. Logistic regression models included the three matching variables and ethnicity. There was no association between risk of non-Hodgkin lymphoma and any of the variables analyzed, including sexually transmitted infections, sexual behavior, blood transfusions, influenza, acne, and either occupational or domestic exposure to zoonotic infections. Non-Hodgkin lymphoma risk was nonsignificantly elevated (odds ratio, 2.99; 95% confidence interval, 0.78-11.51) for those with a history of injecting drug use. Three cases and two controls (odds ratio, 1.32; 95% confidence interval, 0.22-7.98) tested positive to hepatitis C virus infection and none tested positive to human T-lymphotrophic virus type I/II infection. This study provides consistent evidence that sexually transmitted infections and zoonoses are not risk factors for non-Hodgkin lymphoma. PMID:16775166

    Approximately 5% of all malignant lesions are diagnosed as malignant lymphomas, of which 2-3% are localized in the head and neck region. After the squamous cell carcinoma and neoplasms of the salivary glands, malignant lymphomas represent the third most frequent malignant lesion in that region. Malignant lymphomas can be grouped into Hodgkin- and non- Hodgkin lymphomas (NHL) and subdivided into nodal (lymph nodes) and extranodal lymphomas. We present the case of an extranodal non-Hodgkin lymphoma in the left mandible of a 47-year-old woman, who was referred to our department with an unclear swelling, which was supposed to be infectious. After clinical and radiological examination, a biopsy was taken and a CD20 and BCL-6 protein positive non-Hodgkin lymphoma of the large B-cell type (DLBCL) was diagnosed. The patient was treated primarily with immunochemotherapy (R-CHOP protocol) and refused to undergo a subsequent radiotherapy. The 18 months follow-up showed a complete remission of the lymphoma. In this paper, the NHL in the oral and maxillofacial region is presented as a cause of unclear swelling. Important differential diagnostic conditions are discussed. PMID:21656387

    A population-based case-control study evaluated the relationship between soft tissue sarcoma and non-Hodgkin's lymphoma and past exposure to phenoxy herbicides and chlorophenols in western Washington state. A major purpose of the study was to determine if the risk of cancer was elevated in relation to chemicals potentially contaminated with 2,3,7,8-tetra-chlorodibenzo-p-dioxin (TCDD). A total of 160 men with soft tissue sarcoma and 581 men with non-Hodgkin's lymphoma were group-matched with 694 randomly selected controls and were interviewed in person. Among the general population, no increased risks for either cancer were seen in relation to intensity or duration of past exposure to phenoxy herbicides or chlorophenols. Preliminary risk estimates for specific occupations that involve phenoxy herbicide or chlorophenol exposure included: farmer, herbicide formulator, applicator, forest sprayer, farmland sprayer, work in sprayed area, and work with or manufacture chlorophenyls. In addition, the risks of both soft tissue sarcoma and non-Hodgkin's lymphoma were elevated among men with past exposure to various insecticides, organic solvents and metals, and among those with preexisting compromise of the immune system. Multivariate studies are in progress to ascertain the contribution of diverse factors to the risks of soft tissue sarcoma or non-Hodgkin's lymphoma in association with phenoxy herbicides, chlorophenols, and/or TCDD.

    Purpose Vitamin D insufficiency is common in the United States, with low levels linked in some studies to higher cancer incidence, including non-Hodgkin's lymphoma (NHL). Recent data also suggest that vitamin D insufficiency is related to inferior prognosis in some cancers, although there are no data for NHL. Patients and Methods We tested the hypothesis that circulating 25-hydroxyvitamin D [25(OH)D] levels are predictive of event-free survival (EFS) and overall survival (OS) in a prospective cohort of 983 newly diagnosed patients with NHL. 25(OH)D and 1,25-dihydroxyvitamin D [1,25(OH)2D] levels were measured by liquid chromatography-tandem mass spectrometry. Results Mean age at diagnosis was 62 years (range, 19 to 94 years); 44% of patients had insufficient 25(OH)D levels (< 25 ng/mL) within 120 days of diagnosis. Median follow-up was 34.8 months; 404 events and 193 deaths (168 from lymphoma) occurred. After adjusting for known prognostic factors and treatment, 25(OH)D insufficient patients with diffuse large B-cell lymphoma (DLBCL) had inferior EFS (hazard ratio [HR], 1.41; 95% CI, 0.98 to 2.04) and OS (HR, 1.99; 95% CI, 1.27 to 3.13); 25(OH)D insufficient patients with T-cell lymphoma also had inferior EFS (HR, 1.94; 95% CI, 1.04 to 3.61) and OS (HR, 2.38; 95% CI, 1.04 to 5.41). There were no associations with EFS for the other NHL subtypes. Among patients with DLBCL and T-cell lymphoma, higher 1,25(OH)2D levels were associated with better EFS and OS, suggesting that any putative tumor 1-?-hydroxylase activity did not explain the 25(OH)D associations. Conclusion 25(OH)D insufficiency was associated with inferior EFS and OS in DLBCL and T-cell lymphoma. Whether normalizing vitamin D levels in these patients improves outcomes will require testing in future trials. PMID:20713849

  4. Chinese Armillary Spheres

    NASA Astrophysics Data System (ADS)

    Sun, Xiaochun

    The armillary sphere was perhaps the most important type of astronomical instrument in ancient China. It was first invented by Luoxia Hong in the first century BC. After Han times, the structure of the armillary sphere became increasingly sophisticated by including more and more rings representing various celestial movements as recognized by the Chinese astronomers. By the eighth century, the Chinese armillary sphere consisted of three concentric sets of rings revolving on the south-north polar axis. The relative position of the rings could be adjusted to reflect the precession of the equinoxes and the regression of the Moon's nodes along the ecliptic. To counterbalance the defect caused by too many rings, Guo Shoujing from the late thirteenth century constructed the Simplified Instruments which reorganized the rings of the armillary sphere into separate instruments for measuring equatorial coordinates and horizontal coordinates. The armillary sphere was still preserved because it was a good illustration of celestial movements. A fifteenth-century replica of Guo Shoujing's armillary sphere still exists today.

    Hong Kong last month opened the Hong Kong Institute of Biotechnology (HKIB), a nonprofit R and D center. By combining Chinese expertise in medicinal compounds and cell culturing with Western technical and marketing skills, the institute hopes to develop products that could be licensed to Hong Kong or Western films. The institute is also developing experimental cell lines and making genetically engineered versions of promising compounds, taking advantage of the cell-culturing and cloning skills that are highly developed on the mainland. The Shanghai contingent is already involved in one of the institute's projects, an effort to transfer human genes into mouse fibroblasts to create cell lines for research on the molecular mechanisms of learning and memory. Other Chinese researchers are taking part in HKIB's joint venture with Syntex, which was signed last April. The mainland researchers extract candidate medicinal compounds from plants and microorganisms. In Hong Kong, the compounds are tested for their effects on neurotransmitter receptors, while Syntex scientists in Palo Alto study how the same compounds affect enzyme activity and whole cells.

    We propose describing a large kind of cooperation-competition networks by bipartite graphs and their unipartite projections. In the graphs the topological structure describe the cooperation-competition configuration of the basic elements, and the vertex weight describe their different roles in cooperation or results of competition. This complex network description may be helpful for finding and understanding common properties of cooperation-competition systems. In order to show an example, we performed an empirical investigation on the movie cooperation-competition network within recent 80 years in the Chinese mainland. In the net the movies are defined as nodes, and two nodes are connected by a link if a common main movie actor performs in them. The edge represents the competition relationship between two movies for more audience among a special audience colony. We obtained the statistical properties, such as the degree distribution, act degree distribution, act size distribution, and distribution of the total node weight, and explored the influence factors of Chinese mainland movie competition intensity.

    Objective To demonstrate a correlation of C-reactive protein levels with disease stage and response to treatment in Hodgkin's lymphoma patients of the Hematology Service of Santa Casa de São Paulo. Methods A retrospective study based on review of medical records was carried out of 38 patients diagnosed with Hodgkin's lymphoma between October 2010 and December 2012. Three patients met the exclusion criteria, giving a final sample of 35 patients for analysis. C-reactive protein levels >1 mg/dL were considered positive. Results Among the patients analyzed, median age was 29 years, 65% were male and 85% had the classical nodular sclerosis subtype. Twenty-nine (82%) were in the advanced stage and 28% had bulky mass at diagnosis. Seventeen percent had bone marrow invasion by lymphoma. Baseline C-reactive protein levels were associated with both stage (p-value = 0.0035) and presence or absence of B symptoms (p-value = 0.008). The highest C-reactive protein levels were detected in patients with advanced disease while no patients with localized disease had C-reactive protein >5 mg/dL (p-value = 0.02). After the first treatment cycle, C-reactive protein fell to near-normal levels and no direct association with response pattern was found. As the mean follow-up was only 14 months, it was not possible to determine whether relapse was accompanied by a further increase in C-reactive protein. Conclusion Baseline C-reactive protein levels directly correlated with stage and presence or absence of B symptoms, but the degree of improvement with treatment did not correlate with response pattern. After a longer follow-up, it may be possible to assess whether relapse correlates with a further increase in C-reactive protein levels. PMID:26190427

    In countries with ancient civilization of both Eastern world and Western world, after the accumulation of clinical experiences of "empirical medicine" to a sufficient amount; in accordance of their primitive philosophical thoughts, classical medical theories were established to play an important role in guiding the clinical practice of "empirical medicine". Because of the similarity of philosophical thoughts all over the ancient world, their medical theories were also very similar to each other. After the scientific evaluation and improvement, Greek classical medical theories were inherited, refined or abandoned, and then eventually finished their historical mission. Chinese classical medical theories also need the similar scientific identification and improvement for flowing into the authorized main stream of modern medical theory systems to continuously apply their guiding roles in clinical practice. Scholars would better consider the developmental principles of cultures and sciences with a historical viewpoint and an open mind to avoid making mistakes from haughty and prejudice. PMID:23596779

    The experience of social anxiety has largely been investigated among Western populations; much less is known about social anxiety in other cultures. Unlike the Western culture, the Chinese emphasize interdependence and harmony with social others. In addition, it is unclear if Western constructed instruments adequately capture culturally conditioned conceptualizations and manifestations of social anxiety that might be specific to the Chinese. The present study employed a sequence of qualitative and quantitative approaches to examine the assessment of social anxiety among the Chinese people. Interviews and focus group discussions with Chinese participants revealed that some items containing the experience of social anxiety among the Chinese are not present in existing Western measures. Factor analysis was employed to examine the factor structure of the more comprehensive scale. This approach revealed an “other concerned anxiety” factor that appears to be specific to the Chinese. Subsequent analysis found that the new factor—other concerned anxiety—functioned the same as other social anxiety factors in their association with risk factors of social anxiety, such as attachment, parenting, behavioral inhibition/activation, and attitude toward group. The implications of these findings for a more culturally sensitive assessment tool of social anxiety among the Chinese were discussed. PMID:26380367

    Background Non-Hodgkin lymphoma (NHL) comprises biologically and clinically heterogeneous subtypes. Previously, study size has limited the ability to compare and contrast the risk factor profiles among these heterogeneous subtypes. Methods We pooled individual-level data from 17 471 NHL cases and 23 096 controls in 20 case–control studies from the International Lymphoma Epidemiology Consortium (InterLymph). We estimated the associations, measured as odds ratios, between each of 11 NHL subtypes and self-reported medical history, family history of hematologic malignancy, lifestyle factors, and occupation. We then assessed the heterogeneity of associations by evaluating the variability (Q value) of the estimated odds ratios for a given exposure among subtypes. Finally, we organized the subtypes into a hierarchical tree to identify groups that had similar risk factor profiles. Statistical significance of tree partitions was estimated by permutation-based P values (P NODE). Results Risks differed statistically significantly among NHL subtypes for medical history factors (autoimmune diseases, hepatitis C virus seropositivity, eczema, and blood transfusion), family history of leukemia and multiple myeloma, alcohol consumption, cigarette smoking, and certain occupations, whereas generally homogeneous risks among subtypes were observed for family history of NHL, recreational sun exposure, hay fever, allergy, and socioeconomic status. Overall, the greatest difference in risk factors occurred between T-cell and B-cell lymphomas (P NODE < 1.0×10?4), with increased risks generally restricted to T-cell lymphomas for eczema, T-cell-activating autoimmune diseases, family history of multiple myeloma, and occupation as a painter. We further observed substantial heterogeneity among B-cell lymphomas (P NODE < 1.0×10?4). Increased risks for B-cell-activating autoimmune disease and hepatitis C virus seropositivity and decreased risks for alcohol consumption and occupation as a teacher generally were restricted to marginal zone lymphoma, Burkitt/Burkitt-like lymphoma/leukemia, diffuse large B-cell lymphoma, and/or lymphoplasmacytic lymphoma/Waldenström macroglobulinemia. Conclusions Using a novel approach to investigate etiologic heterogeneity among NHL subtypes, we identified risk factors that were common among subtypes as well as risk factors that appeared to be distinct among individual or a few subtypes, suggesting both subtype-specific and shared underlying mechanisms. Further research is needed to test putative mechanisms, investigate other risk factors (eg, other infections, environmental exposures, and diet), and evaluate potential joint effects with genetic susceptibility.

  14. Classical Diamagnetism Revisited

    NASA Astrophysics Data System (ADS)

    Saha, Arnab; Lahiri, Sourabh; Jayannavar, A. M.

    The well-known Bohr-van Leeuwen Theorem states that the orbital diamagnetism of classical charged particles is identically zero in equilibrium. However, results based on real space-time approach using the classical Langevin equation predicts non-zero diamagnetism for classical unbounded (finite or infinite) systems. Here we show that the recently discovered Fluctuation Theorems, namely, the Jarzynski Equality or the Crooks Fluctuation Theorem surprisingly predicts a free energy that depends on magnetic field as well as on the friction coefficient, in outright contradiction to the canonical equilibrium results. However, in the cases where the Langevin approach is consistent with the equilibrium results, the Fluctuation Theorems lead to results in conformity with equilibrium statistical mechanics. The latter is demonstrated analytically through a simple example that has been discussed recently.

    We consider classical models of the kicked rotor type, with piecewise linear kicking potentials designed so that momentum changes only by multiples of a given constant. Their dynamics display quasilocalization of momentum, or quadratic growth of energy, depending on the arithmetic nature of the constant. Such purely classical features mimic paradigmatic features of the quantum kicked rotor, notably dynamical localization in momentum, or quantum resonances. We present a heuristic explanation, based on a classical phase space generalization of a well-known argument, that maps the quantum kicked rotor on a tight-binding model with disorder. Such results suggest reconsideration of generally accepted views that dynamical localization and quantum resonances are a pure result of quantum coherence.

    Investments in the extension of health insurance coverage, the strengthening of public health services, as well as primary care and better hospitals, highlights the emerging role of healthcare as part of China’s new growth regime, based on an expansion of services, and redistributive policies. Such investments, apart from their central role in terms of relief for low-income people, serve to rebalance the Chinese economy away from export-led growth toward the domestic market, particularly in megacity-regions as Shanghai and the Pearl River Delta, which confront the challenge of integrating migrant workers. Based on the paper by Gusmano and colleagues, one would expect improvements in population health for permanent residents of China’s cities. The challenge ahead, however, is how to address the growth of inequalities in income, wealth and the social wage. PMID:25774379

    Three hundred and six coal samples were taken from main coal mines of twenty-six provinces, autonomous regions, and municipalities in China, according to the resource distribution and coal-forming periods as well as the coal ranks and coal yields. Nitrogen was determined by using the Kjeldahl method at U. S. Geological Survey (USGS), which exhibit a normal frequency distribution. The nitrogen contents of over 90% Chinese coal vary from 0.52% to 1.41% and the average nitrogen content is recommended to be 0.98%. Nitrogen in coal exists primarily in organic form. There is a slight positive relationship between nitrogen content and coal ranking. ?? 2011 Science Press, Institute of Geochemistry, CAS and Springer Berlin Heidelberg.

    2010-08-18

    We show how to enlarge the covariance group of any classical field theory in such a way that the resulting "covariantized" theory is 'essentially equivalent' to the original. In particular, our technique will render any classical field theory generally covariant, that is, the covariantized theory will be spacetime diffeomorphism-covariant and free of absolute objects. Our results thus generalize the well-known parametrization technique of Dirac and Kucha\\v{r}. Our constructions apply equally well to internal covariance groups, in which context they produce natural derivations of both the Utiyama minimal coupling and St\\"uckelberg tricks.

    Sun, Xiaochun

    Star observations can be traced back to as early as the twenty-third century BC in ancient China. By the fifth century BC, the Chinese had named the 28 asterisms that formed the basic reference points for the Chinese equatorial coordinate system. By the first century BC, the Chinese had developed a unique system of constellations that reflected Chinese cosmological ideas with the central theme of the correlation between Heaven and Man. Star charts have been discovered on tomb ceilings dating back to Han times. But most of them are illustrative in their presentation of stars. The Dunhuang star maps from the ninth century, the star maps in the Xin yixiang fa yao of the eleventh century, and the Suzhou Astronomical Planisphere of the thirteenth century are examples of precise star maps from ancient China.

    Coale has suggested that cultural factors exert a significant influence on fertility reduction; countries in the "Chinese cultural circle" would be the first to show fertility decline. In China, the view was that traditional Chinese culture contributed to increased population. This paper examines the nature of the relationship between Chinese culture and fertility. Attention was directed to a comparison of fertility rates of developing countries with strong Chinese cultural influence and of fertility within different regions of China. Discussion was followed by an explanation of the theoretical impact of Chinese culture on fertility and direct and indirect beliefs and practices that might either enhance or hinder fertility decline. Emigration to neighboring countries occurred after the Qing dynasty. Fertility after the 1950s declined markedly in Japan, Singapore, Hong Kong, South Korea, Taiwan, and mainland China: all countries within the Chinese cultural circle. Other countries within the Chinese circle which have higher fertility, yet lower fertility than other non-Chinese cultural countries, are Malaysia, Thailand, and Indonesia. Within China, regions with similar fertility patterns are identified as coastal regions, central plains, and mountainous and plateau regions. The Han ethnic group has lower fertility than that of ethnic minorities; regions with large Han populations have lower fertility. Overseas Chinese in East Asian countries also tend to have lower fertility than their host populations. Chinese culture consisted of the assimilation of other cultures over 5000 years. Fertility decline was dependent on the population's desire to limit reproduction, favorable social mechanisms, and availability of contraception: all factors related to economic development. Chinese culture affects fertility reduction by affecting reproductive views and social mechanisms directly, and indirectly through economics. Confucianism emphasizes collectivism, self-reliance, education and cultivation of moral character, and atheism. Confucian beliefs that interfere with fertility decline are the advocacy of self-sufficient livelihood, the emphasis on family and lineage, autocracy, patriarchy and feudal rule, the 5 constant virtues, contempt for labor and working people, science and technology, and a closed-door policy. Socialism hindered fertility decline by promoting population growth as a symbol of the superiority of socialism and by lack of recognition of population or environmental problems in socialist countries. The goal is to accept Westernization, reduce obstacles, develop economically, and use cultural influence positive to fertility decline. PMID:12317926

    Background: Chemotherapy for lymph nodes cancer is often composed of several drugs that are used in a treatment program. Objectives: The aim of this study was to perform a cost-utility analysis of IEV regimen (ifosfamide, epirubicin and etoposide) versus ESHAP regimen (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin) in patients with lymphoma in the south of Iran. Patients and Methods: This was a cost-utility analysis done as a cross-sectional study in the south of Iran. Using decision tree, expected costs, quality -adjusted life years (QALYs) and the incremental cost-effectiveness ratio (ICER) were estimated. In addition, the robustness of results was examined by sensitivity analysis. Results: The results of this study indicated that the total lymphoma patients were about 65 people that 27 patients received IEV regimen and 38 patients ESHAP (43 patients with Hodgkin’s and 22 with non-Hodgkin lymphoma). The results of decision tree showed that in the IEV arm, the expected cost was $20952.93 and the expected QALYs was 3.89 and in the ESHAP arm, the expected cost was $31691.74 and the expected QALYs was 3.86. Based on the results of the study, IEV regimen was cost-effective alternative to the ESHAP regimen. Conclusions: According to the results of this study, it is recommended that oncologists use IEV instead of ESHAP in the treatment of patients with lymphoma and because of high costs of IEV drug costs, it is suggested that IEV drugs should be covered by insurance.

    Purpose: Hodgkin lymphoma (HL) survivors are at an increased risk of stroke because of carotid artery irradiation. However, for early-stage HL involved node radiation therapy (INRT) reduces the volume of normal tissue exposed to high doses. Here, we evaluate 3-dimensional conformal radiation therapy (3D-CRT), volumetric-modulated arc therapy (VMAT), and proton therapy (PT) delivered as INRT along with the extensive mantle field (MF) by comparing doses to the carotid arteries and corresponding risk estimates. Methods and Materials: We included a cohort of 46 supradiaphragmatic stage I-II classical HL patients. All patients were initially treated with chemotherapy and INRT delivered as 3D-CRT (30 Gy). For each patient, we simulated MF (36 Gy) and INRT plans using VMAT and PT (30 Gy). Linear dose-response curves for the 20-, 25-, and 30-year risk of stroke were derived from published HL data. Risks of stroke with each technique were calculated for all patients. Statistical analyses were performed with repeated measures analysis of variance. Results: The mean doses to the right and left common carotid artery were significantly lower with modern treatment compared with MF, with substantial patient variability. The estimated excess risk of stroke after 20, 25, and 30 years was 0.6%, 0.86%, and 1.3% for 3D-CRT; 0.67%, 0.96%, and 1.47% for VMAT; 0.61%, 0.96%, and 1.33% for PT; and 1.3%, 1.72%, and 2.61% for MF. Conclusions: INRT reduces the dose delivered to the carotid arteries and corresponding estimated risk of stroke for HL survivors. Even for the subset of patients with lymphoma close to the carotid arteries, the estimated risk is low.

    Chinese journals in epidemiology, preventive medicine and public health contain much that is of potential international interest. However, few non-Chinese speakers are acquainted with this literature. This article therefore provides an overview of the contemporary scene in Chinese biomedical journal publication, Chinese bibliographic databases and Chinese journals in epidemiology, preventive medicine and public health. The challenge of switching to English as the medium of publication, the development of publishing bibliometric data from Chinese databases, the prospect of an Open Access publication model in China, the issue of language bias in literature reviews and the quality of Chinese journals are discussed. Epidemiologists are encouraged to search the Chinese bibliographic databases for Chinese journal articles. PMID:18826604

  7. Quantum particles from classical statistics

    Quantum particles and classical particles are described in a common setting of classical statistical physics. The property of a particle being "classical" or "quantum" ceases to be a basic conceptual difference. The dynamics differs, however, between quantum and classical particles. We describe position, motion and correlations of a quantum particle in terms of observables in a classical statistical ensemble. On the other side, we also construct explicitly the quantum formalism with wave function and Hamiltonian for classical particles. For a suitable time evolution of the classical probabilities and a suitable choice of observables all features of a quantum particle in a potential can be derived from classical statistics, including interference and tunneling. Besides conceptual advances, the treatment of classical and quantum particles in a common formalism could lead to interesting cross-fertilization between classical statistics and quantum physics.

  17. The role of pixantrone in the treatment of non-Hodgkin's lymphoma.

    PubMed

    Borchmann, Peter; Schnell, Roland

    2005-08-01

    Pixantrone is an anthraquinone-based inhibitor of topoisomerase II. It is similar to both the anthracycline doxorubicin and the anthracenedione mitoxantrone, but lacks the 5,8-dihydroxy substitution pattern of mitoxantrone, and has a tricyclic system unlike the tetracyclic structure seen with anthracyclines. Anthracyclines are the most active drugs in lymphoma therapy, but their use is limited by their cumulative and irreversible cardiotoxicity. Pixantrone was developed to improve the toxicity profile of the current anthracyclines and anthracenediones while maintaining their activity. Interestingly, pixantrone showed no measurable cardiotoxicity compared with its parent compound mitoxantrone or other anthracyclines at equi-effective doses in several animal models. Together with its superior cytotoxic activity in leukaemia and lymphoma models, these features render the drug a promising candidate for clinical development in indolent and aggressive non-Hodgkin's lymphoma. In this review, the latest results of the use of pixantrone in indolen-t and aggressive non-Hodgkin's lymphomas are summarised. PMID:16050797

    Molecular typing of HLA class II loci has been performed on a sample of 196 patients with Hodgkin lymphoma. Division of patients into histological categories - nodular sclerosing Hodgkin disease versus all other types - shows significant overall association of the nodular sclerosing group with the HLA class II region. Haplotypes and alleles defined for the four loci typed - DRB1, DQA1, DQB1, and DPB1 - were present in both excess and deficit in the nodular sclerosing sample. Some of the effects are attributable to particular DRB1 and DQB1 alleles, while other effects are best explained by haplotypes marking the entire class II region or to particular combinations of alleles from two or more loci. These data also explain why earlier studies showed HLA linkage but not association, and they substantiate the specific involvement of the immune system in certain neoplastic diseases. 38 refs., 6 tabs.

    The authors retrospectively assessed with sonography the prevalence of thyroid gland abnormalities in 30 patients who underwent radiation therapy for Hodgkin disease between 1962 and 1984. Doses ranged from 3,000 to 4,500 rad (3,000-4,500 cGy). Abnormalities were found in the sonograms of 24 patients and included unilateral (n = 6) or bilateral (n = 2) atrophy; multiple hypoechoic lesions smaller than 0.75 cm (n = 18); and dominant cystic (n = 2), solid (n = 3), or complex lesions (n = 4) larger than 0.75 cm. The risk of development of an abnormality increased as the time from irradiation increased and was comparable between patients who did and did not receive chemotherapy as part of the treatment regimen. Although the pathologic correlates of the various abnormalities seen on sonograms may differ, the findings indicate a need for long-term follow-up of patients who underwent cervical irradiation for Hodgkin disease.

    Eighty-four evaluable patients with advanced Hodgkin's disease (Stages IIB, IIIA age > 35 or mixed cellularity or lymphocyte depletion histology, IIIB, IVA, and IVB) were treated with alternating monthly MOPP and Adriamycin, bleomycin, dacarbazine, and vinblastine (ABDV). Radiation therapy (RT), 2000 rads in two weeks, was given to areas of initial bulky disease in untreated patients. Complete remission (CR) rates were 80% for previously untreated, 65% for prior RT or minimal chemotherapy treated, and 50% for heavily pretreated patients. Among 49 previously untreated patients there were no primary treatment failures. The estimated two-year relapse rate for the CR group was 9%. The therapeutic effectiveness of this program may have been due to either or both of the following elements: (1) two non-cross-resistant drug combinations; (2) low dose adjuvant RT to initial sites of bulky disease. These early results are among the best reported for the treatment of advanced Hodgkin's disease.

  1. Acute myocardial infarction after heart irradiation in young patients with Hodgkin's disease

    Forty-seven patients younger than 40 years at the time of the diagnosis, and irradiated to the mediastinum for Hodgkin's disease at Turku University Central Hospital from 1977 to 1982, were regularly followed for 56 to 127 months after therapy. Two patients developed an acute myocardial infarction ten and 50 months after cardiac irradiation at the age of only 28 and 24 years, respectively. None of the patients died from lymphoma within five years from the diagnosis, but one of the infarctions was eventually fatal. Since acute myocardial infarction is rare in this age group, the result suggests strongly that prior cardiac irradiation is a risk factor for acute myocardial infarction. The possibility of radiation-induced myocardial infarction should be taken into account both in treatment planning and follow-up of patients with Hodgkin's disease.

    The non-Hodgkin lymphoma is a neoplastic entity that presents in extranodal form in 20 % of cases, usually occurs as solitary or generalized lymphadenopathy. There may be misdiagnosis if it manifests as primary extranodal disease because the primary infiltration may occur with different organs, despite the difficulty of diagnosis of primary extranodal location of non-Hodgkin lymphoma, histological and immunohistochemical studies are effective in preventing misdiagnosis. The presentation of this case is to describe this condition in its extranodal variety with cardiac infiltration in a 23 year-old woman with progressive dyspnea. Tumor mass was detected in right-atrial, venous catheterization biopsy was performed, this enabled the histopathological diagnosis and establish treatment. We present experiences from the attention of the case and review of the literature with special reference to diagnosis and treatment. PMID:25760753

    A 20-year-old man contracted Hodgkin's disease and was treated with mantle radiotherapy. Heart block developed 11 years later. Electrocardiograms revealed predominant atrioventricular (AV) block and occasional AV conduction. Intracardiac electrograms demonstrated that the site of AV block was above the level of the His bundle. A permanent transvenous pacemaker was implanted. Seven months later the patient died of complications from cryptococcal meningitis. Pathological study of the heart revealed marked arteriosclerosis with fibrosis of the epicardium, myocardium, and endocardium. Examination of the conduction system revealed extensive arteriolosclerosis of the sinoatrial node and its approaches. In addition, there was marked fibrosis of the approaches to the AV node, the AV bundle, and both bundle branches. There was no evidence of Hodgkin's disease. This case documents the rare occurrence of AV block due to tissue destruction by radiotherapy. There was a good correlation between block proximal to the His bundle recording site and fibrosis of the approaches to the AV node.

    Advances in chemotherapy and radiation therapy have allowed the vast majority of patients with Hodgkin lymphoma to be cured, but some of these patients develop treatment-related complications, including second malignancies, cardiovascular disease, and thyroid disease. Efforts to decrease exposure of patients to more chemotherapy or radiation therapy than is necessary to cure their disease have led to a trend toward shortened treatment regimens in patients with low-risk disease. Predicting which patients will relapse, and therefore might benefit from a more intense treatment regimen, has been a clinical challenge. PET has emerged as a useful modality in the diagnosis and management of Hodgkin lymphoma, and has been studied as a potential tool to help the oncologist to utilize the optimal chemotherapy and radiation therapy regimen for each patient.

    Corroborating evidence related to the role of aberrations on one-carbon metabolism (OCM) genes has been inconsistent. We evaluated the association between polymorphisms in 12 single nucleotide polymorphisms (SNPs) in 8 OCM genes (CBS, FPGS, FTHFD, MTRR, SHMT1, SLC19A1, TCN1, and TYMS), and non-Hodgkin lymphoma (NHL) risk in a multi-ethnic population which includes Malay, Chinese and Indian ethnic subgroups. Cases (N?=?372) and controls (N?=?722) were genotyped using the Sequenom MassARRAY platform. Our results of the pooled subjects showed a significantly enhanced NHL risk for CBS Ex9?+?33C?>?T (T versus C: OR 1.55, 95% CI 1.22-1.96, P?=?0.0003), CBS Ex18-319G?>?A (A versus G: OR 1.15, 95% CI 1.14-1.83; P?=?0.002), SHMT1 Ex12?+?236 T?>?C (T versus C: OR 1.44, 95% CI 1.15-1.81, P?=?0.002), and TYMS Ex8?+?157C?>?T (T versus C: OR 1.29, 95% CI 1.06-1.57, P?=?0.01). Haplotype analysis for CBS SNPs showed a significantly decreased risk of NHL in subjects with haplotype CG (OR 0.69, 95% CI 0.56-0.86, P?=?<0.001). The GG haplotype for the FTHFD SNPs showed a significant increased risk of NHL (OR 1.40, 95% CI 1.12-1.76, P?=?0.002). For the TYMS gene, haplotype CAT at TYMS (OR 0.67, 95% CI 0.49-0.90, P?=?0.007) was associated with decreased risk of NHL, while haplotype TAC (OR 1.29, 95% CI 1.05-1.58, P?=?0.01) was found to confer increased risk of NHL. Our study suggests that variation in several OCM genes (CBS, FTHFD, SHMT1, TCN1, and TYMS) may influence susceptibility to NHL. PMID:25384508

    Purpose: The recognition of the true prevalence of cardiac toxicity after mediastinal radiotherapy requires very long follow-up and a precise diagnostic procedure. Cardiac magnetic resonance imaging (MRI) permits excellent quantification of cardiac function and identification of localized myocardial defects and has now been applied to a group of 20-year Hodgkin's disease survivors. Methods and materials: Of 143 patients treated with anterior mediastinal radiotherapy (cobalt-60, median prescribed dose 40 Gy) for Hodgkin's disease between 1978 and 1985, all 53 survivors were invited for cardiac MRI. Of those, 36 patients (68%) presented for MRI, and in 31 patients (58%) MRI could be performed 20-28 years (median, 24) after radiotherapy. The following sequences were acquired on a 1.5-T MRI: transversal T1-weighted TSE and T2-weighted half-fourier acquisition single-shot turbo-spin-echo sequences, a steady-state free precession (SSFP) cine sequence in the short heart axis and in the four-chamber view, SSFP perfusion sequences under rest and adenosine stress, and a SSFP inversion recovery sequence for late enhancement. The MRI findings were correlated with previously reconstructed doses to cardiac structures. Results: Clinical characteristics and reconstructed doses were not significantly different between survivors undergoing and not undergoing MRI. Pathologic findings were reduced left ventricular function (ejection fraction <55%) in 7 (23%) patients, hemodynamically relevant valvular dysfunction in 13 (42%), late myocardial enhancement in 9 (29%), and any perfusion deficit in 21 (68%). An association of regional pathologic changes and reconstructed dose to cardiac structures could not be established. Conclusions: In 20-year survivors of Hodgkin's disease, cardiac MRI detects pathologic findings in approximately 70% of patients. Cardiac MRI has a potential role in cardiac imaging of Hodgkin's disease patients after mediastinal radiotherapy.

These classifications are based on the discoveries of modern immunology and are relying on the marking techniques for the identification of the T, B and U lymphocytes. Arguments are presented why these modern nomenclatures should progressively replace the Rappaport classification which preceded the major developments of modern immunology. The Kiel nomenclature is briefly described. PMID:309837

    BACKGROUND Multicolour fluorescent in situ hybridization was utilized to detect sperm aneuploidy for chromosomes 13, 21, X and Y in testicular cancer and Hodgkin's lymphoma chemotherapy patients. METHODS Aneuploidy was assessed before, and 6, 12 and/or 18-24 months after, the initiation of chemotherapy, and compared with age matched controls. 635 396 sperm were scored blindly with 5000 sperm/patient/chromosome/ time point, where sperm was available. (First two phrases have been reversed). RESULTS Comparing testicular cancer and Hodgkin's lymphoma patients to each other and with controls, cancer-specific differences were identified. Hodgkin's lymphoma patients, particularly, exhibited significantly increased aneuploidy frequencies for all chromosomes throughout treatment. At 6 months, all cancer patients showed significantly increased frequencies of XY disomy and nullisomy for chromosomes 13 and 21. In general, aneuploidy frequencies declined to pretreatment levels 18 months after treatment initiation, but increased aneuploidy frequencies persisted in some chromosomes for up to 24 months. CONCLUSIONS Because of elevated aneuploidy frequencies prior to and up to 24 months from the start of chemotherapy, patients should receive genetic counselling about the potentially increased risk of an aneuploid conceptus from sperm cryopreserved prior to chemotherapy, and for conceptions up to 2 years after the initiation of treatment.

    The malignant Hodgkin and Reed-Sternberg cells of Hodgkin's lymphoma (HL) and HL-derived B cell lines were previously shown to be resistant to different apoptotic stimuli. We show here that cytochrome c fails to stimulate caspases-9 and -3 activation in cytosolic extracts of HL-derived B cells, which is due to high level expression of X-linked inhibitor of apoptosis (XIAP). Coimmunoprecipitation studies revealed that XIAP, apoptosis protease-activating factor–1, and caspase-3 are complexed in HL-derived B cell lysates. Even after stimulation with exogenous cytochrome c and dATP, XIAP impairs the proteolytic processing and activation of caspase-3. In cytosolic extracts, inhibition of XIAP by the second mitochondria-derived activator of caspases (Smac)/DIABLO, or immunodepletion of XIAP restores cytochrome c–triggered processing and activation of caspase-3. Smac or a Smac-derived agonistic peptide also sensitized intact HL-derived B cells for the apoptotic action of staurosporine. Finally, Hodgkin and Reed-Sternberg cells of primary tumor HL tissues also constitutively and abundantly express XIAP. The results of this paper suggest that high level XIAP expression is a hallmark of HL, which may play a crucial role in resistance to apoptosis. PMID:12874265

    Patients with early-staged Hodgkin's disease have had a higher relapse rate following radiotherapy alone if they have B symptoms, large mediastinal masses, hilar involvement, or stage III disease. From June 1988 to December 1989, 27 previously untreated patients with early-staged Hodgkin's disease with adverse features for disease-free survival received combined-modality therapy. Seventeen patients had stage I or II disease, 10 had stage III, 5 had B symptoms, 13 had large mediastinal masses, and 6 had peripheral masses measuring 10 cm or more in diameter. All patients initially received three cycles of a novel chemotherapeutic regimen combining Novantrone (mitoxantrone, American Cyanamid Company), vincristine, vinblastine, and prednisone (NOVP). Twenty-four patients with clinically staged I or II disease with adverse features or stage III disease did not undergo laparotomy; three patients had favorable stage I or II disease and at laparotomy had stage III disease. Radiotherapy-treatment fields depended on the extent of nodal involvement. Twenty-six patients completed all therapy as planned to complete remission (CR) and one of these has had progression; she is in second CR following additional radiotherapy. With a median follow-up of 12 months, all patients are alive. Tolerance to treatment was excellent with only grade 1 or 2 nausea, alopecia and myalgias, and brief myelosuppression. NOVP is an effective adjuvant chemotherapy regimen for inducing responses, with minimal toxicity, prior to definitive radiotherapy for patients with early-staged Hodgkin's disease.

    In recent years, Chinese service industry is developing rapidly. Compared with developed countries, service quality should be the bottleneck for Chinese service industry. On the background of three major telecommunications service providers in China, the functions of customer perceived utilities are established. With the goal of consumer's perceived utility maximization, the classic Nash equilibrium solution and quantum equilibrium solution are obtained. Then a numerical example is studied and the changing trend of service quality and customer perceived utility is further analyzed by the influence of the entanglement operator. Finally, it is proved that quantum game solution is better than Nash equilibrium solution.

    A unitary interaction coupling two parties enables quantum communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff between the achievable rates of specific types of forward and backward communication. Our first result shows that for any bipartite unitary gate, coherent classical communication is no more difficult than classical communication -- they have the same achievable rate regions. Previously this result was known only for the unidirectional capacities (i.e., the boundaries of the tradeoff). We then relate the tradeoff curve for two-way coherent communication to the tradeoff for two-way quantum communication and the tradeoff for coherent communiation in one direction and quantum communication in the other.

    We investigate how isospin affects the geometrical shape and energy of classical soliton solutions of topological charges $B=1-4,8$ in the Skyrme model. The novel approach in our work is that we study classically isospinning Skyrmions beyond the rigid-body approximation; that is, we explicitly allow the soliton solutions to deform and to break the symmetries of the static configurations. Our fully three-dimensional relaxation calculations reveal that the symmetries of isospinning Skyrme solitons can differ significantly from the ones of the static configurations. In particular, isospinning Skyrmion solutions can break up into lower-charge Skyrmions, can deform into new solution types that do not exist at vanishing angular frequency $\\omega$ or energy degeneracy can be removed. These types of deformations have been largely ignored in previous work on modeling nuclei by quantized Skyrmion solutions.

    We consider the possibility that classical dynamical systems display motion in their lowest energy state, forming a time analogue of crystalline spatial order. Challenges facing that idea are identified and overcome. We display arbitrary orbits of an angular variable as lowest-energy trajectories for nonsingular Lagrangian systems. Dynamics within orbits of broken symmetry provide a natural arena for formation of time crystals. We exhibit models of that kind, including a model with traveling density waves.

    Background Hypercholesterolemia is an important key contributory factor for ischemic heart disease and is associated with age, high blood pressure, a family history of hypercholesterolemia, and diabetes. Chinese herbal medicines have been used for a long time as lipid-lowering agents. Objectives To assess the effects of Chinese herbal medicines on hypercholesterolemia. Search strategy We searched the following databases: The Cochrane Library (issue 8, 2010), MEDLINE (until July 2010), EMBASE (until July 2010), Chinese BioMedical Database (until July 2010), Traditional Chinese Medical Literature Analysis and Retrieval System (until July 2010), China National Knowledge Infrastructure (until July 2010), Chinese VIP Information (until July 2010), Chinese Academic Conference Papers Database and Chinese Dissertation Database (until July 2010), and Allied and Complementary Medicine Database (until July 2010). Selection criteria We considered randomized controlled clinical trials in hypercholesterolemic participants comparing Chinese herbal medicines with placebo, no treatment, and pharmacological or non-pharmacological interventions. Data collection and analysis Two review authors independently extracted data and assessed the risk of bias. We resolved any disagreements with this assessment through discussion and a decision was achieved based by consensus. We assessed trials for the risk of bias against key criteria: random sequence generation, allocation concealment, blinding of participants, incomplete outcome data, selective outcome reporting and other sources of bias. Main results We included 22 randomized trials (2130 participants). The mean treatment duration was 2.3 ± 1.3 months (ranging from one to six months). Twenty trials were conducted in China and 18 trials were published in Chinese. Overall, the risk of bias of included trials was high or unclear. Five different herbal medicines were evaluated in the included trials, which compared herbs with conventional medicine in six comparisons (20 trials), or placebo (two trials). There were no outcome data in any of the trials on cardiovascular events and death from any cause. One trial each reported well-being (no significant differences) and economic costs. No serious adverse events were observed. Xuezhikang was the most commonly used herbal formula investigated. A significant effect on total cholesterol (two trial, 254 participants) was shown in favor of Xuezhikang when compared with inositol nicotinate (mean difference (MD) ?0.90 mmol/L, 95% confidence interval (CI) ?1.13 to ?0.68) . Authors’ conclusions Some herbal medicines may have cholesterol-lowering effects. Our findings have to be interpreted with caution due to high or unclear risk of bias of the included trials.

    The phenolic methyl ether 3,5-dimethoxytoluene (DMT) is a major scent compound of many modern rose varieties, and its fragrance participates in the characteristic “tea scent” that gave their name to Tea and Hybrid Tea roses. Among wild roses, phenolic methyl ether (PME) biosynthesis is restricted to Chinese rose species, but the progenitors of modern roses included both European and Chinese species (e.g., Rosa chinensis cv Old Blush), so this trait was transmitted to their hybrid progeny. The last steps of the biosynthetic pathways leading to DMT involve two methylation reactions catalyzed by the highly similar orcinol O-methyltransferases (OOMT) 1 and 2. OOMT1 and OOMT2 enzymes exhibit different substrate specificities that are consistent with their operating sequentially in DMT biosynthesis. Here, we show that these different substrate specificities are mostly due to a single amino acid polymorphism in the phenolic substrate binding site of OOMTs. An analysis of the OOMT gene family in 18 species representing the diversity of the genus Rosa indicated that only Chinese roses possess both the OOMT2 and the OOMT1 genes. In addition, we provide evidence that the Chinese-rose-specific OOMT1 genes most probably evolved from an OOMT2-like gene that has homologues in the genomes of all extant roses. We propose that the emergence of the OOMT1 gene may have been a critical step in the evolution of scent production in Chinese roses. PMID:18413608

    Genome instability is a hallmark of cancer. Diffuse large B-cell lymphoma (DLBCL) is the most common form of non-Hodgkin lymphoma with high levels of chromosomal aberrations. The purpose of this study was to characterize chromosomal aberrations in Chinese DLBCL patients and to compare chromosomal abnormalities between germinal centre B-cell-like (GCB) and non-GCB subgroups. Fluorescence in situ hybridization, G-band cytogenetics and immunohistochemistry were performed in 231 cases of de novo DLBCL. We demonstrated that the rate of abnormal and complex karyotypes was 89.1% (139/156) and 92.8% (129/139), respectively. We found a total of 490 structural chromosomal aberrations, including 96 frequent and recurring structural alterations. Most importantly, we identified several rare or novel chromosomal alterations: eight gains (5, 13, 14q, 17, 19p, 20, 21p, Y), one loss (21) and three recurrent translocations [t(7;15)(q22;q22), t(3;20)(p24;q13.1), t(2;3)(q21;q25)]. Moreover, the frequent recurrent genomic imbalance between GCB and non-GCB subgroups was different. Finally, we discovered two cases of concurrent IGH-BCL6 and MYC rearrangements. The rate of abnormal karyotypes in DLBCL patients of Chinese descent was similar to that of Western countries, but some common karyotypes were different, as were the abnormal karyotypes of GCB and non-GCB subgroups. Our discovery of rare and novel abnormal karyotypes may represent unique chromosomal alterations in Chinese DLBCL patients. PMID:23135954

    Lymphomas constitute approximately 0.15% of malignant mammary neoplasms. Less than 0.5% of all malignant lymphomas involve the breast primarily. Primary non-Hodgkin breast lymphoma is usually right sided. The combined therapy approach, with chemotherapy and radiotherapy, is the most successful treatment. Mastectomy offers no benefit in the treatment of primary non-Hodgkin breast lymphoma. To the author's knowledge, this is the first published case of primary non-Hodgkin breast lymphoma reported with conventional ultrasonography, elastography (both freehand and acoustic radiation force impulse imaging), digital mammography, contrast-enhanced digital mammography, and pathology findings. A 45-year-old woman presented with a lump in the right breast for 2 months. There was no evidence of systemic lymphoma or leukemia when the breast lesion was detected. Imaging findings were negative for lymphoma. Ipsilateral lymph nodes were not palpable. The mass was resected, and histopathology findings were diagnostic of non-Hodgkin lymphoma. Immunohistochemistry was confirmatory of non-Hodgkin lymphoma, diffuse large cell type of B-cell lineage. Although primary and secondary lymphomas of the breast are rare entities, they should be considered in the differential diagnosis of breast malignancies. PMID:25831151

    The study aims to comprehensively assess the profiles of myositis-specific autoantibodies (MSAs) in Chinese patients with polymyositis (PM)/dermatomyositis (DM) and compare them with a Japanese cohort. One hundred forty-five Chinese patients (68 classic DM, 25 clinically amyopathic DM [CADM], and 52 PM) and 165 Japanese patients (56 classic DM, 52 CADM, and 57 PM) were recruited. MSAs were measured with immunoprecipitation, enzyme-linked immunosorbent assay, or immunoprecipitation-immunoblotting. MSA frequencies were compared. The overall frequency of anti-melanoma differentiation-associated gene 5 (MDA5) antibodies was significantly higher in the Chinese patients than in the Japanese cohort (36.6 % [53/145] versus 15.8 % [26/165], respectively, P?Chinese patients were observed in the classic DM subset (14.7 % [10/68] versus 46.4 % [26/56], respectively, P?Chinese patients with PM/DM was established. The differences in MSA frequencies in the Chinese cohort and Japanese cohort suggest underlying genetic and/or environmental differences between these two populations. Key Messages • A significantly higher frequency of anti-melanoma differentiation-associated gene 5 (MDA5) antibodies was observed in Chinese patients with polymyositis/dermatomyositis (PM/DM) than in Japanese patients. • Our findings suggest that distinct genetic and/or local environmental factors affect Chinese and Japanese patients with PM/DM, who have been considered a "homogeneous" population in previous studies.

    Cell lines derived from Hodgkin's disease may provide a clue to the nature of Sternberg-Reed cells. In the current study, the establishment of an Epstein-Barr-virus-negative lymphoblastoid cell line, derived from the pleural fluid of a patient with the nodular sclerosis type of Hodgkin's disease, is described. The morphologic and immunologic cell marker findings indicate that this cell line is derived from Sternberg-Reed cells. The immunologic findings and a chromosomal analysis are in agreement with a B-lymphocyte origin of these cultured cells. Extrapolation of the results to Hodgkin's disease in vivo would indicate that Hodgkin's disease, like most non-Hodgkin's lymphomas, is the result of B-cell proliferation. PMID:3881158

    2001-06-01

    We consider the classical evolution of a particle on a graph by using a time-continuous Frobenius-Perron operator that generalizes previous propositions. In this way, the relaxation rates as well as the chaotic properties can be defined for the time-continuous classical dynamics on graphs. These properties are given as the zeros of some periodic-orbit zeta functions. We consider in detail the case of infinite periodic graphs where the particle undergoes a diffusion process. The infinite spatial extension is taken into account by Fourier transforms that decompose the observables and probability densities into sectors corresponding to different values of the wave number. The hydrodynamic modes of diffusion are studied by an eigenvalue problem of a Frobenius-Perron operator corresponding to a given sector. The diffusion coefficient is obtained from the hydrodynamic modes of diffusion and has the Green-Kubo form. Moreover, we study finite but large open graphs that converge to the infinite periodic graph when their size goes to infinity. The lifetime of the particle on the open graph is shown to correspond to the lifetime of a system that undergoes a diffusion process before it escapes.

    Quantum statistical methods that are commonly used for the derivation of classical thermodynamic properties are extended to classical mechanical properties. The usual assumption that every real motion of a classical mechanical system is represented by a sharp trajectory is not testable and is replaced by a class of fuzzy models, the so-called maximum entropy (ME) packets. The fuzzier are the compared classical and quantum ME packets, the better seems to be the match between their dynamical trajectories. Classical and quantum models of a stiff rod will be constructed to illustrate the resulting unified quantum theory of thermodynamic and mechanical properties.

    2015-09-01

    In a quantum theory of gravity spacetime behaves classically when quantum probabilities are high for histories of geometry and field that are correlated in time by the Einstein equation. Probabilities follow from the quantum state. This quantum perspective on classicality has important implications. (a) Classical histories are generally available only in limited patches of the configuration space on which the state lives. (b) In a given patch, states generally predict relative probabilities for an ensemble of possible classical histories. (c) In between patches classical predictability breaks down and is replaced by quantum evolution connecting classical histories in different patches. (d) Classical predictability can break down on scales well below the Planck scale, and with no breakdown in the classical equations of motion. We support and illustrate (a)-(d) by calculating the quantum transition across the de Sitter-like throat connecting asymptotically classical, inflating histories in the no-boundary quantum state. This supplies probabilities for how a classical history on one side transitions and branches into a range of classical histories on the opposite side. We also comment on the implications of (a)-(d) for the dynamics of black holes and eternal inflation.

    The widespread use of Chinese herbal medicine (CHM) and the associated adverse reactions has attracted the attention of researchers and physicians. Reports have shown that several types of CHM can cause liver injury, with increasing numbers of cases reported every year. The difficulty in characterizing CHM-induced liver injury stems from clinical manifestations, diagnosis and pathogenesis. The clinical manifestations are varied, but gastrointestinal symptoms are the majority. The Council for International Organizations of Medical Sciences scale is currently the most commonly used method for assessing causality in cases of medicine-induced liver injury with excellent sensitivity, specificity and predictive validity. However, the pathogenesis of CHM-induced liver injury is not well understood. The classic view encompasses a contribution from “toxic metabolites” that either elicit an immune response or directly affect cellular biochemical processes or functions. In addition, poor quality and inappropriate clinical use of CHMs contribute to safety concerns. To ensure the safe use of CHMs and decrease the number of hepatotoxic cases, clinicians, researchers and pharmaceutical companies should share responsibility by regulating clinical use, strengthening basic toxicology research and establishing a strict quality control system.

  3. Quantum Logic as Classical Logic

    E-print Network

    2015-04-27

    We propose a semantic representation of the standard quantum logic QL within a classical, normal modal logic, and this via a lattice-embedding of orthomodular lattices into Boolean algebras with one modal operator. Thus our classical logic is a completion of the quantum logic QL. In other words, we refute Birkhoff and von Neumann's classic thesis that the logic (the formal character) of Quantum Mechanics would be non-classical as well as Putnam's thesis that quantum logic (of his kind) would be the correct logic for propositional inference in general. The propositional logic of Quantum Mechanics is modal but classical, and the correct logic for propositional inference need not have an extroverted quantum character. One normal necessity modality suffices to capture the subjectivity of observation in quantum experiments, and this thanks to its failure to distribute over classical disjunction. The key to our result is the translation of quantum negation as classical negation of observability.

    Background Development of novel therapeutic drugs and regimens for cancer treatment has led to improvements in patient long-term survival. This success has, however, been accompanied by the increased occurrence of second primary cancers. Indeed, patients who received regional radiotherapy for Hodgkin’s Lymphoma (HL) or breast cancer may develop, many years later, a solid metachronous tumor in the irradiated field. Despite extensive epidemiological studies, little information is available on the genetic changes involved in the pathogenesis of these solid therapy-related neoplasms. Methods Using microsatellite markers located in 7 chromosomal regions frequently deleted in sporadic esophageal cancer, we investigated loss of heterozygosity (LOH) and microsatellite instability (MSI) in 46 paired (normal and tumor) samples. Twenty samples were of esophageal carcinoma developed in HL or breast cancer long-term survivors: 14 squamous cell carcinomas (ESCC) and 6 adenocarcinomas (EADC), while 26 samples, used as control, were of sporadic esophageal cancer (15 ESCC and 11 EADC). Results We found that, though the overall LOH frequency at the studied chromosomal regions was similar among metachronous and sporadic tumors, the latter exhibited a statistically different higher LOH frequency at 17q21.31 (p = 0.018). By stratifying for tumor histotype we observed that LOH at 3p24.1, 5q11.2 and 9p21.3 were more frequent in ESCC than in EADC suggesting a different role of the genetic determinants located nearby these regions in the development of the two esophageal cancer histotypes. Conclusions Altogether, our results strengthen the genetic diversity among ESCC and EADC whether they occurred spontaneously or after therapeutic treatments. The presence of histotype-specific alterations in esophageal carcinoma arisen in HL or breast cancer long-term survivors suggests that their transformation process, though the putative different etiological origin, may retrace sporadic ESCC and EADC carcinogenesis.

  5. Hodgkin’s lymphoma emerging radiation treatment techniques: trade-offs between late radio-induced toxicities and secondary malignant neoplasms

    2013-01-01

    Background Purpose of this study is to explore the trade-offs between radio-induced toxicities and second malignant neoplasm (SMN) induction risk of different emerging radiotherapy techniques for Hodgkin’s lymphoma (HL) through a comprehensive dosimetric analysis on a representative clinical model. Methods Three different planning target volume (PTVi) scenarios of a female patient with supradiaphragmatic HL were used as models for the purpose of this study. Five treatment radiation techniques were simulated: an anterior-posterior parallel-opposed (AP-PA), a forward intensity modulated (FIMRT), an inverse intensity modulated (IMRT), a Tomotherapy (TOMO), a proton (PRO) technique. A radiation dose of 30 Gy or CGE was prescribed. Dose-volume histograms of PTVs and organs-at-risk (OARs) were calculated and related to available dose-volume constraints. SMN risk for breasts, thyroid, and lungs was estimated through the Organ Equivalent Dose model considering cell repopulation and inhomogeneous organ doses. Results With similar level of PTVi coverage, IMRT, TOMO and PRO plans generally reduced the OARs’ dose and accordingly the related radio-induced toxicities. However, only TOMO and PRO plans were compliant with all constraints in all scenarios. For the IMRT and TOMO plans an increased risk of development of breast, and lung SMN compared with AP-PA and FIMRT techniques was estimated. Only PRO plans seemed to reduce the risk of predicted SMN compared with AP-PA technique. Conclusions Our model–based study supports the use of advanced RT techniques to successfully spare OARs and to reduce the risk of radio-induced toxicities in HL patients. However, the estimated increase of SMNs’ risk inherent to TOMO and IMRT techniques should be carefully considered in the evaluation of a risk-adapted therapeutic strategy. PMID:23360559

  9. Chinese English Learners' Strategic Competence.

    2015-12-01

    The present study aims to investigate Chinese English learners' ability to use communication strategies (CSs). The subjects are put in a relatively real English referential communication setting and the analyses of the research data show that Chinese English learners, when encountering problems in foreign language (FL) communication, are characterized by the frequent use of substitution, approximation, circumlocution, literal translation, exemplification, word-coinage, repetition, and the infrequent use of cultural-knowledge and paralinguistic CSs. The rare use of paralinguistic strategies is found to be typical of Chinese English learners. The high frequency of literal translation, one first language (L1)-based strategy in our study sample, suggests that FL learners' use of L1-based CSs may depend more upon the developmental stage of their target language than the typology distance between L1 and the target language. The frequency of repetition reveals one fact that the Chinese English learners lack variety and flexibility in their use of CSs. Based on these findings, it was indicated that learners' use of CSs is influenced by a variety of factors, among which the development stage of their interlanguage and their cultural background are identified as two important factors. Some implications are finally suggested for the English foreign language teaching practice in China. PMID:25134668

    1995-06-01

    T-cell-rich B-cell lymphoma (TCRBCL) is a recently described variant of non-Hodgkin's lymphoma. It may arise de novo or secondary to follicular lymphoma and large B-cell lymphoma. We present here seven cases of TCRBCL to emphasize a peculiar relationship to lymphocyte-predominant Hodgkin's disease. Morphologically, the neoplastic populations of all TCRBCLs, in addition to centroblast-like and immunoblast-like cells, comprised a few L+H-like elements. These neoplastic cells were all regularly scattered in a majority of reactive small T-lymphocytes as well as histiocytes. Moreover, tumour cells of TCRBCL, including the L+H-like elements of TCRBCL, expressed LCA and L26 but did not stain for Leu-M1 and BerH2, as is the case with the Reed-Sternberg cell L+H variant of lymphocyte-predominant Hodgkin's disease. Furthermore, the L26 immunoreaction in one of the cases, which otherwise presented as typical TCRBCL, disclosed a small subcapsular area resembling nodular paragranuloma because some few foci consisting of mature B lymphocytes with occasional L+H-like elements were seen. This also holds true for a second of the TCRBCLs presented that obviously coexisted with recurrent Hodgkin's paragranuloma 10 years after the primary manifestation. These findings indicate a close connection between TCRBCL and lymphocyte-rich Hodgkin's disease, and it may even be speculated as to whether TCRBCL represents merely a phenotypically different manifestation of this Hodgkin's subtype. Although the data presented here will not provide sufficient proof of this hypothesis, it seems clear that the nosology of TCRBCL in the context of current lymphoma classifications requires further elucidation.

    OBJECTIVE--To examine the relation between the risk of childhood leukaemia and non-Hodgkin's lymphoma and proximity of residence to nuclear installations in England and Wales. DESIGN--Observed and expected numbers of cases were calculated and analysed by standard methods based on ratios of observed to expected counts and by a new statistical test, the linear risk score test, based on ranks and designed to be sensitive to excess incidence in close proximity to a putative source of risk. SETTING--Electoral wards within 25 km of 23 nuclear installations and six control sites that had been investigated for suitability for generating stations but never used. SUBJECTS--Children below age 15 in England and Wales, 1966-87. MAIN OUTCOME MEASURE--Registration of any leukaemia or non-Hodgkin's lymphoma. RESULTS--In none of the 25 km circles around the installations was the incidence ratio significantly greater than 1.0. The only significant results for the linear risk score test were for Sellafield (P = 0.00002) and Burghfield (P = 0.031). The circles for Aldermaston and Burghfield overlap; the incidence ratio was 1.10 in each. One of the control sites gave a significant linear risk score test result (P = 0.020). All the tests carried out were one sided with P values estimated by simulation. CONCLUSION--There is no evidence of a general increase of childhood leukaemia or non-Hodgkin's lymphoma around nuclear installations. Apart from Sellafield, the evidence for distance related risk is very weak. PMID:8086902

    Leptomeningeal infiltration of the brain or spinal cord by neoplastic cells may occur as complication of solid or hematopoietic tumors such as non-Hodgkin lymphoma. Previously rare, this event is becoming increasingly common as newer therapies can prolong survival but may not achieve therapeutic concentration in the central nervous system. Although prognosis is poor, early diagnosis and aggressive treatment may lead to prolonged survival and/or improvement of quality of life. We report a case of a 69-year-old man with leptomeningeal infiltration by non-Hodgkin lymphoma revealed by F-FDG-PET/CT and confirmed by subsequent spinal MRI and cerebrospinal fluid cytology.

    2014-08-01

    Tasked with the challenge to build better and better computers, quantum computing and classical computing face the same conundrum: the success of classical computing systems. Small quantum computing systems have been demonstrated, and intermediate-scale systems are on the horizon, capable of calculating numeric results or simulating physical systems far beyond what humans can do by hand. However, to be commercially viable, they must surpass what our wildly successful, highly advanced classical computers can already do. At the same time, those classical computers continue to advance, but those advances are now constrained by thermodynamics, and will soon be limited by the discrete nature of atomic matter and ultimately quantum effects. Technological advances benefit both quantum and classical machinery, altering the competitive landscape. Can we build quantum computing systems that out-compute classical systems capable of some logic gates per month? This article will discuss the interplay in these competing and cooperating technological trends.

    In a recent Nature article, Morin et al. uncovered a novel role for chromatin modification in driving the progression of two non-Hodgkin lymphomas (NHLs), follicular lymphoma and diffuse large B-cell lymphoma. Through DNA and RNA sequencing of 117 tumor samples and 10 assorted cell lines, the authors identified and validated 109 genes with multiple mutations in these B-cell NHLs. Of the 109 genes, several genes not previously linked to lymphoma demonstrated positive selection for mutation including two genes involved in histone modification, MLL2 and MEF2B.

    Febrile cholestatic liver disease is an extremely unusual presentation of Hodgkin lymphoma (HL). The liver biopsy of a 40-year-old man with febrile episodes and cholestatic laboratory pattern disclosed an uncommon subtype of HL, a nodular lymphocyte-predominant HL (NLPHL). Liver involvement in the early stage of the usually indolent NLPHL’s clinical course suggests an aggressiveness and unfavorable outcome. Emphasizing a liver biopsy early in the diagnostic algorithm enables accurate diagnosis and appropriate treatment. Although rare, HL should be considered in the differential diagnosis of cholestasis.

    The role of angiogenesis in the growth of lymphomas and survival of patients with leukemias and other hematological malignancies has become evident since 1994. Angiogenic factors, such as vascular endothelial growth factor and its receptors together with other tumor microenvironment components, including myelo-monocytic cell, mast cells, endothelial progenitor cells, and circulating endothelial cells, have been shown to be important in the progression and maintenance of lymphoproliferative disorders. In this review article, we present an overview of the literature focusing on the relationship between angiogenesis and disease progression and the recent advantages in the antiangiogenic treatment in human non-Hodgkin lymphomas.

Selective splenic imaging was accomplished with /sup 99m/Tc-labeled heat-treated red blood cells, an LFOV gamma camera, a 30/sup 0/ bilateral rotating slant hole collimator, and bilateral slant hole tomographic software. Relative splenic volumes were plotted over time, and correlated with clinical and histologic data. Eight patients with Hodgkin disease and other lymphomas were examined. Volume response to epinephrine appears to be significantly less in abnormal spleens, and may serve to identify patients with unequivocally normal spleens prior to treatment.

    One hundred twenty-one patients with newly diagnosed, previously untreated Hodgkin disease underwent abdominal and pelvic computed tomographic (CT) scanning and bipedal lymphography. These studies were followed by staging laparotomy, which included biopsy of the liver, retroperitoneal and mesenteric lymph nodes, and splenectomy. Correlation of the results of the imaging studies with the histopathologic diagnoses revealed a small - but significant - increased accuracy of lymphography compared with CT in assessing the retroperitoneal lymph nodes. The theoretical advantages of CT scanning in detecting lymphomatous deposits in lymph nodes about the celiac axis and the mesentery, or in the liver and spleen, were not confirmed.

    Lymphomas are the most common non-epithelial tumors of the head and neck and its incidence has increased in recent decades. Around 10% are extranodal lymphomas, and in more than half of the cases are located in Waldeyer's lymphatic ring. The most common presenting symptoms are odynophagia and dysphagia (68%), and symptoms suggestive of oropharyngeal cancer such as cough, hoarseness, earache, feeling of occupation in the back of the mouth, throat or neck. In non-Hodgkin lymphomas in this location, B symptoms (weight loss, fever and sweating) are rare (5%). The histological subtype of each individual lymphoma affects the evaluation, therapy and prognosis. PMID:24034764

    Background: There are a few published studies about prognostic markers of Epstein-B virus (EBV) related to outcomes in pediatric Hodgkin Lymphoma (HL). Objectives: We aimed to investigate the prognostic value and effect of EBV on survival by using biopsy materials in children and adolescents diagnosed with HL. Patients and Methods: EBV LMP-1 expression was examined using immunohistochemical methods in 58 tumor samples. Clinical features, overall survival (OS) and failure free survival time (FFS) were compared between EBV LMP-1 positive and negative patients. Results: In 20 (35%) patients tumors were LMP-1 positive. When compared with patients above 10 years old, EBV LMP-1 was often positive in patients under 10 years old (30% vs. 70%, P = 0.02). In our most cases having B symptoms and advanced stage, EBV positiveness in Hodgkin Reed-Stenberg cells (H-RS) was not a significant determinant for survival (P = 0.78). Half of the past clinical trials in childhood HL reported longer survival rates in EBV LMP-1 positive patients. In some trials similar to our results there was no significant relationship between EBV and prognosis. Conclusions: The reason of diminished EBV positiviness may be related to technical methods such as not using immunohistochemical and in situ hybridization for EBER antigen but in laboratory conditions painting of control tissues with EBV impair this probability. In addition, cases enrolled to our study were living in Istanbul where social and economical factors are improved rather than generally. PMID:26635935

    Pixantrone (BBR-2778) is a novel mitoxantrone-like drug, which lacks the 5,8-dihyroxy substitution groups thought to be responsible for the cardiac toxicity associated with mitoxantrone. In Phase I/II single-agent pixantrone clinical trials, neutropenia was the dose-limiting toxicity and the maximum tolerated dose was 150 mg/m(2)/week for 3 weeks every 4 weeks. In relapsed aggressive non-Hodgkin's lymphomas, weekly single-agent pixantrone 85 mg/m(2) for 3 weeks every 4 weeks was associated with a 27% overall response and a 15% complete response. When intensively pretreated patients with relapsed aggressive non-Hodgkin's lymphoma were treated with a cyclophosphamide, pixantrone, vincristine and prednisolone regimen (pixantrone substituted for doxorubicin in standard regimen [cyclophosphamide, doxorubicin, vincristine and prednisolone regimen (CHOP)]), the overall response was 74% and complete response 57%. In the BBR-2778, methylprednisolone, cisplatin and cytosine arabinoside (BSHAP) regimen, 58% overall response and 37% complete response were achieved. A number of randomised studies of pixantrone (BBR-2778) in patients with relapsed indolent or aggressive lymphomas are ongoing. PMID:17922631

    Nineteen children treated for Wilms' tumor (thirteen cases) or Hodgkin's disease (six cases) with cytostatic agents and/or radiotherapy were studied cytogenetically on lymphocytes cultivated from blood samples drawn after at least 1 year of complete remission after end of therapy. A reference group of children was matched for age, sex, and residence. The frequencies of sister chromatid exchange (5.4 versus 5.6 SCE/cell), and chromosome damage type gaps (6.6 versus 7.1%) and breaks (1.9 versus 1.9%) were not different in the two groups, but exchange type aberrations were more frequent in the patients (0.9 versus 0.06%). Fifty karyotypes were analyzed in all but two cases of Hodgkin's disease. The overall frequency of stable (3.1 versus 3.8%) and unstable (1.7 versus 1.4%) structural chromosome changes such as translocations, deletions, chromatid exchanges, and dicentrics were not different in the patient and the control groups. If the chromosome data reflect a general cancer risk, this risk cannot be considerably higher among the cancer-treated children.

    Introduction Burkitt's lymphoma accounts for approximately 25% of lymphomas diagnosed in children of developmental age. The tumor is localized mainly in the intestine (usually in the ileocecal region), mesenteric lymph nodes and extraperitoneal space. The clinical symptoms are non-specific and include: abdominal pain, vomiting, gastrointestinal bleeding, and acute abdomen suggesting appendicitis or intestinal intussusception. On ultrasound examination, Burkitt's lymphoma may manifest itself in various ways, depending on the origin of the lesion. Aim The aim of this paper was to review the ultrasound manifestation of abdominal Burkitt's lymphoma in children. Material and methods The analysis included 15 pediatric patients with Burkitt's non-Hodgkin lymphoma in the abdominal cavity. The mean age of the patients was 9.5. Abdominal and gastrointestinal ultrasound examinations were conducted using a Siemens scanner with a convex transducer of 3.5–5 MHz and linear array transducer of L4 – 7.5 MHz. Results Ultrasound examinations conducted in the group of 15 patients revealed pathological masses localized in the gastric wall in 3 patients (20%), in the ileocecal region in 10 patients (67%) and a disseminated process in 2 patients (13%). In 12 patients with a diagnosed Burkitt's non-Hodgkin lymphoma in an extragastric localization, differences in the morphology of the lesions were observed. Conclusions The clinical and ultrasound picture of abdominal Burkitt's lymphoma in children is variable. A careful ultrasound assessment of all abdominal organs conducted with the use of convex and linear probes increases the chances of establishing an adequate diagnosis. PMID:26672593

    Quantum polyhedra constructed from angular momentum operators are the building blocks of space in its quantum description as advocated by Loop Quantum Gravity. Here we extend previous results on the semiclassical properties of quantum polyhedra. Regarding tetrahedra, we compare the results from a canonical quantization of the classical system with a recent wave function based approach to the large-volume sector of the quantum system. Both methods agree in the leading order of the resulting effective operator (given by an harmonic oscillator), while minor differences occur in higher corrections. Perturbative inclusion of such corrections improves the approximation to the eigenstates. Moreover, the comparison of both methods leads also to a full wave function description of the eigenstates of the (square of the) volume operator at negative eigenvalues of large modulus. For the case of general quantum polyhedra described by discrete angular momentum quantum numbers we formulate a set of quantum operators fulfilling in the semiclassical regime the standard commutation relations between momentum and position. Differently from previous formulations, the position variable here is chosen to have dimension of (Planck) length squared which facilitates the identification of quantum corrections. Finally, we provide expressions for the pentahedral volume in terms of Kapovich-Millson variables.

    Complete mitochondrial D-loop sequences of 231 samples were used to explore the origin and genetic diversity of Chinese cattle. Phylogenetical analysis of these sequences revealed both Bos taurus and Bos indicus mitochondrial types in Chinese cattle. Four of the previously identified mitochondrial DNA lineages (T1-T4) were identified in the Bos taurus type, including lineage T1, which was found for the first time in Chinese cattle. Two lineages (I1 and I2) were identified in the Bos indicus type. Our results support the suggestion that the Yunnan-Guizhou Plateau is the domestication site of Chinese zebu. We also found evidence that Tibetan cattle originated from taurine and zebu cattle. The distribution pattern of Chinese cattle breeds was closely related to the geographical and climatic background. It was possible to divide Chinese cattle in this study into two major groups: northern and southern cattle. PMID:17121603

    Chinese medicine is a historic cultural legacy of China. It has made a significant contribution to medicine and healthcare for generations. The development of Chinese herbal medicine analysis is emphasized by the Chinese pharmaceutical industry. This study has carried out the experimental analysis of ten kinds of Chinese herbal powder including Fritillaria powder, etc., based on the photoacoustic spectroscopy (PAS) method. First, a photoacoustic spectroscopy system was designed and constructed, especially a highly sensitive solid photoacoustic cell was established. Second, the experimental setup was verified through the characteristic emission spectrum of the light source, obtained by using carbon as a sample in the photoacoustic cell. Finally, as the photoacoustic spectroscopy analysis of Fritillaria, etc., was completed, the specificity of the Chinese herb medicine analysis was verified. This study shows that the PAS can provide a valid, highly sensitive analytical method for the specificity of Chinese herb medicine without preparing and damaging samples.

    Background The past 3 decades have witnessed a boost in science development in China; in parallel, more and more Chinese scientific journals are indexed by the Journal Citation Reports issued by Thomson Reuters (SCI). Evaluation of the performance of these Chinese SCI journals is necessary and helpful to improve their quality. This study aimed to evaluate these journals by calculating various journal self-citation rates, which are important parameters influencing a journal impact factor. Methodology/Principal Findings We defined three journal self-citation rates, and studied these rates for 99 Chinese scientific journals, almost exhausting all Chinese SCI journals currently available. Likewise, we selected 99 non-Chinese international (abbreviated as ‘world’) journals, with each being in the same JCR subject category and having similar impact factors as their Chinese counterparts. Generally, Chinese journals tended to be higher in all the three self-citation rates than world journal counterparts. Particularly, a few Chinese scientific journals had much higher self-citation rates. Conclusions/Significance Our results show that generally Chinese scientific journals have higher self-citation rates than those of world journals. Consequently, Chinese scientific journals tend to have lower visibility and are more isolated in the relevant fields. Considering the fact that sciences are rapidly developing in China and so are Chinese scientific journals, we expect that the differences of journal self-citation rates between Chinese and world scientific journals will gradually disappear in the future. Some suggestions to solve the problems are presented. PMID:23173041

    Purpose: Cure rates of early Hodgkin lymphoma (HL) are high, and avoidance of late complications and second malignancies have become increasingly important. This comparative treatment planning study analyzes to what extent target volume reduction to involved-node (IN) and intensity-modulated (IM) radiotherapy (RT), compared with involved-field (IF) and three-dimensional (3D) RT, can reduce doses to organs at risk (OAR). Methods and Materials: Based on 20 computed tomography (CT) datasets of patients with early unfavorable mediastinal HL, we created treatment plans for 3D-RT and IMRT for both the IF and IN according to the guidelines of the German Hodgkin Study Group (GHSG). As OAR, we defined heart, lung, breasts, and spinal cord. Dose-volume histograms (DVHs) were evaluated for planning target volumes (PTVs) and OAR. Results: Average IF-PTV and IN-PTV were 1705 cm{sup 3} and 1015 cm{sup 3}, respectively. Mean doses to the PTVs were almost identical for all plans. For IF-PTV/IN-PTV, conformity was better with IMRT and homogeneity was better with 3D-RT. Mean doses to the heart (17.94/9.19 Gy for 3D-RT and 13.76/7.42 Gy for IMRT) and spinal cord (23.93/13.78 Gy for 3D-RT and 19.16/11.55 Gy for IMRT) were reduced by IMRT, whereas mean doses to lung (10.62/8.57 Gy for 3D-RT and 12.77/9.64 Gy for IMRT) and breasts (left 4.37/3.42 Gy for 3D-RT and 6.04/4.59 Gy for IMRT, and right 2.30/1.63 Gy for 3D-RT and 5.37/3.53 Gy for IMRT) were increased. Volume exposed to high doses was smaller for IMRT, whereas volume exposed to low doses was smaller for 3D-RT. Pronounced benefits of IMRT were observed for patients with lymph nodes anterior to the heart. IN-RT achieved substantially better values than IF-RT for almost all OAR parameters, i.e., dose reduction of 20% to 50%, regardless of radiation technique. Conclusions: Reduction of target volume to IN most effectively improves OAR sparing, but is still considered investigational. For the time being, IMRT should be considered for large PTVs especially when the anterior mediastinum is involved.

    2007-01-01

    M51, whose name comes from being the 51st entry in Charles Messier's catalog, is considered to be one of the classic examples of a spiral galaxy. At a distance of about 30 million light-years from Earth, it is also one of the brightest spirals in the night sky. A composite image of M51, also known as the Whirlpool Galaxy, shows the majesty of its structure in a dramatic new way through several of NASA's orbiting observatories. X-ray data from NASA's Chandra X-ray Observatory reveals point-like sources (purple) that are black holes and neutron stars in binary star systems. Chandra also detects a diffuse glow of hot gas that permeates the space between the stars. Optical data from the Hubble Space Telescope (green) and infrared emission from the Spitzer Space Telescope (red) both highlight long lanes in the spiral arms that consist of stars and gas laced with dust. A view of M51 with the Galaxy Evolution Explorer telescope shows hot, young stars that produce lots of ultraviolet energy (blue).

    The textbook spiral structure is thought be the result of an interaction M51 is experiencing with its close galactic neighbor, NGC 5195, which is seen just above. Some simulations suggest M51's sharp spiral shape was partially caused when NGC 5195 passed through its main disk about 500 million years ago. This gravitational tug of war may also have triggered an increased level of star formation in M51. The companion galaxy's pull would be inducing extra starbirth by compressing gas, jump-starting the process by which stars form.

    Patients with Hodgkin's Disease (HD) occasionally develop monomorphic lymphomas in which mononuclear cells, usually large in size, grow in sheets, and in which there are few reacting cells or classic Reed-Sternberg (RS) cells. Twelve patients of this type were reviewed to determine the nature of the monomorphic growth. Paraffin-embedded tissue sections from the original diagnostic HD and the monomorphic growths were stained for Leu-M1 (CD15), leukocyte common antigen (LCA, CD45), pan B-cell markers LN1, LN2, and L26, and pan T-cell marker UCHL1 (CD45R) reactive in paraffin-embedded tissues. Cases were included only if the original diagnostic material had the classic histopathologic features of HD, if there was a separate monomorphic growth (in place or time), and if sufficient materials from both phases were available for study. Original diagnoses of HD included nodular sclerosing (NS; 8 cases); lymphocyte predominant (LP; 2 cases); mixed cellularity (MC; 1 case); and lymphocyte depleted (LD: 1 case) types. RS cells in the eight cases of NS HD and one case of MC HD were generally Leu-M1 and LN2 positive, and L26, LN1, UCHL1, and LCA negative. RS cells in one case of NS HD were LCA positive in addition to Leu-M1, LN1, and LN2. Two cases of NS HD showed L26 positive RS cells. Conversely, RS cells and lymphocytic-histiocytic (L and H) variants in the cases of LP HD were Leu-M1 and LN2 negative, and LCA and LN1 positive. The one case of LD HD possessed RS cells that were negative for Leu-M1, but positive for LCA, L26, LN1, and LN2. In seven cases (4 NS, 2 LP, 1 LD) the monomorphic growths possessed a B-cell phenotype (LCA, L26, and LN1 positive; Leu-M1 and UCHL1 negative). In the remaining cases (4 NS, 1 MC), the monomorphic growths were Leu-M1 positive, and displayed phenotypes similar to the RS cells of the original NS HD. Southern blot analysis was performed on the monomorphic components of five cases and showed some form of immunoglobulin gene rearrangement in each (4 cases: rearranged heavy chain-joining region gene; 1 case: rearranged Mu chain-constant region gene). Two of these cases expressed L26 and LN1 in the monomorphic phases. Despite apparent immunoglobulin gene rearrangement, one case expressed T-cell antigens Leu-4 (CD3) and Leu-1 (CD5), in addition to Leu-M1 (CD15).(ABSTRACT TRUNCATED AT 400 WORDS) Images Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 PMID:2297052

  9. [Aristolochic acid nephropathy ("Chinese herb nephropathy")].

    Aristolochic acid nephropathy is a renal disease of toxic origin characterized by a progressive interstitial fibrosis and frequently associated with urinary tract cancer. It was initially reported in Belgium after the intake of slimming pills containing root extracts of a Chinese herb, Aristolochia fangchi. In the following decades, numerous cases have been reported worldwide, particularly in Asian countries. Several experimental models of aristolochic acid nephropathy (AAN) have been designed. They confirm the causal link between AA exposure and the onset of acute and chronic renal toxicity, as well as urinary tract cancer. These experimental models offer the opportunity to study the mechanisms of renal interstitial fibrosis and carcinogenesis. In terms of public health, the history of this nephropathy demonstrates that it is mandatory to submit all "natural medicinal products" to the same controls of efficacy, toxicity and conformity applied to the classical drugs derived from the pharmaceutical producers. Any unusual observation of renal failure and/or cancer of the urinary tract should lead to a questioning about any prior exposure to AA. The confirmation of the ingestion of AA containing compounds by phytochemical analysis is not always feasible. However, the renal biopsy remains a crucial diagnostic point through the demonstration of a hypocellular interstitial fibrosis with a decreasing corticomedullary gradient, mostly in advanced cases of kidney disease. Moreover, the detection of AA-related DNA adducts within a renal or urothelial tissue sample could confirm the prior AA exposure. The persistence of these specific DNA adducts in renal tissue is very long (up to 20 years). Finally, considering the highly carcinogenic properties of AA, a systematic endo-urological screening is absolutely necessary. PMID:26515658

    The distribution of non-Hodgkin lymphoma (NHL) subtypes varies around the world, but a systematic study of South-eastern Europe (SEEU) has never been done. Therefore, we evaluated the relative frequencies of NHL subtypes in three SEEU countries - Croatia, Romania and Macedonia. Five expert haematopathologists reviewed 632 consecutive cases of newly diagnosed NHL from the three SEEU countries using the World Health Organization classification. The results were compared to 399 cases from North America (NA) and 580 cases from Western Europe (WEU). The proportions of B- and T-cell NHL and the sex distribution in SEEU were similar to WEU and NA. However, the median ages of patients with low- and high-grade B-NHL in SEEU (60 and 59 years, respectively) were significantly lower than in NA (64 and 68 years, respectively; P < 0·05). SEEU had a significantly lower proportion of low-grade B-NHL (46·6%) and higher proportion of high-grade B-NHL (44·5%) compared to both WEU (54·5% and 36·4%, respectively) and NA (56·1% and 34·3%, respectively). There were no significant differences in the relative frequencies of T-NHL subtypes. This study provides new insights into differences in the relative frequencies of NHL subtypes in different geographic regions. Epidemiological studies are needed to better characterize and explain these differences. PMID:26213902

    We define "coherent communication" in terms of a simple primitive, show it is equivalent to the ability to send a classical message with a unitary or isometric operation, and use it to relate other resources in quantum information theory. Using coherent communication, we are able to generalize super-dense coding to prepare arbitrary quantum states instead of only classical messages. We also derive single-letter formulae for the classical and quantum capacities of a bipartite unitary gate assisted by an arbitrary fixed amount of entanglement per use.

  5. Auspicious birth dates among Chinese in California.

    The number eight is considered lucky in Chinese culture, e.g. the Beijing Olympics began at 8:08 pm on 8/8/2008. Given the potential for discretion in selecting particular dates of labor induction or scheduled Cesarean section (C-section), we consider whether Chinese-American births in California occur disproportionately on the 8th, 18th, or 28th day of the month. We find 2.3% "too many" Chinese births on these auspicious birth dates, whereas Whites show no corresponding increase. The increase in Chinese births is driven by higher parity C-sections: the number of repeat C-sections is 6% "too high" on auspicious birth dates. Sons born to Chinese parents account for the entire increase; daughter deliveries do not seem to be timed to achieve "lucky" birth dates. We also find avoidance of repeat C-section deliveries on the 4th, 14th, and 24th of the month, considered unlucky in Chinese culture. Finally, we replicate earlier work finding that Friday the 13th delivery dates are avoided and document a particularly large decrease among Chinese. For Whites and Chinese in California, mothers with higher levels of education are particularly likely to avoid delivering on the 13th. PMID:26160600
