    A subset of patients with advanced classical Hodgkin’s lymphoma is refractory to standard therapies. Therefore, it is relevant to identify new biologically-based prognostic markers. Recently, tumor associated macrophages have been proposed as a factor that predicts survival, although contradictory results have also been reported. Here we analyzed four macrophage markers (CD68, CD163, LYZ, and STAT1) using immunohistochemistry and automated quantification, in two independent series of advanced classical Hodgkin’s lymphoma (n=266 and 103 patients, respectively). Our results did not confirm that specific macrophage immunohistochemical markers could be used as surrogates for gene expression profiling studies. Survival analyses did not show correlation between CD163, LYZ or STAT1 and either failure-free or disease-specific survival. There was an association between CD68 and disease-specific survival, but it was not consistent in both series. In conclusion, individual tumor associated macrophage markers cannot be used to predict outcome before technical standardization and prospective validation in independent series of patients with comparable stages and treatments.

    Chromosomal breakpoints affecting immunoglobulin (IG) loci are recurrent in many subtypes of B-cell lymphomas. However, despite the predominant B-cell origin of the Hodgkin and Reed-Sternberg (HRS) cells in classical Hodgkin lymphoma (cHL), the presence of chromosomal translocations in IG loci has not yet been systematically explored. Therefore, we have investigated a series of cHL for chromosomal breakpoints in the IGH

    Lymphomas associated with Warthin's tumor (WT) are extremely rare. Here, we report the simultaneous occurrence of lymphocyte-rich classical Hodgkin's lymphoma (LRCHL) and WT in a 78-year-old patient whose symptoms included an enlargement of the left parotid gland. Upon parotidectomy, the tissue specimen showed a WT with extensive replacement of the lymphoid stroma by small lymphocytes and some scattered Reed-Sternberg cells; however, the oncocytic epithelium was preserved. Further investigation revealed mediastinal and abdominal lymphadenopathy, consistent with stage IVB disease. To our knowledge, this is the first case report of LRCHL associated with WT. The lymphoid stroma in WT is part of the systemic lymphoid tissue and thus may be involved in the dissemination of the lymphoma. This case serves as a reminder that a careful evaluation of the histomorphological and immunohistological features of the lymphoid tissue is required for a WT biopsy. PMID:23849380

    Background Mediastinal gray zone lymphoma is a newly recognized entity with transitional morphological and immunophenotypic features between the nodular sclerosis subtype of Hodgkin’s lymphoma and primary mediastinal large B-cell lymphoma. Diagnostic criteria for mediastinal gray zone lymphoma are still challenging, and the optimal therapy is as yet undetermined. Epigenetic changes have been implicated in the loss of the B-cell program in classical Hodgkin’s lymphoma, and might provide a basis for the immunophenotypic alterations seen in mediastinal gray zone lymphoma. Design and Methods We performed a large-scale DNA methylation analysis of microdissected tumor cells to investigate the biological underpinnings of mediastinal gray zone lymphoma and its association with the related entities classical Hodgkin’s lymphoma and primary mediastinal large B-cell lymphoma, making comparisons with the presumptively less related diffuse large B-cell lymphoma. Results Principal component analysis demonstrated that mediastinal gray zone lymphoma has a distinct epigenetic profile intermediate between classical Hodgkin’s lymphoma and primary mediastinal large B-cell lymphoma but remarkably different from that of diffuse large B-cell lymphoma. Analysis of common hypo- and hypermethylated CpG targets in mediastinal gray zone lymphoma, classical Hodgkin’s lymphoma, primary mediastinal large B-cell lymphoma and diffuse large B-cell lymphoma was performed and confirmed the findings of the principal component analysis. Based on the epigenetic profiles we were able to establish class prediction models utilizing genes such as HOXA5, MMP9, EPHA7 and DAPK1 which could distinguish between mediastinal gray zone lymphoma, classical Hodgkin’s lymphoma and primary mediastinal large B-cell lymphoma with a final combined prediction of 100%. Conclusions Our data confirm a close relationship between mediastinal gray zone lymphoma and both classical Hodgkin’s lymphoma and primary mediastinal large B-cell lymphoma. However, important differences were observed as well, allowing a clear distinction from both parent entities. Thus, mediastinal gray zone lymphoma cannot be assigned to either classical Hodgkin’s lymphoma or primary mediastinal large B-cell lymphoma, validating the decision to create an intermediate category in the World Health Organization classification.

    Purpose: While the International Prognostic Score (IPS) is the gold standard for risk-stratifying patients with classical Hodgkin lymphoma (cHL), these criteria do not accurately predict outcome. As cytokines are critically involved in driving cHL, we tested whether pretreatment serum cytokine levels could provide additional prognostic information. Experimental Design: Thirty cytokines were measured in pretreatment serum from 140 cHL patients and compared with 50 non-lymphoma controls. Patients were followed for event-free and overall survival, and Cox proportional hazards regression models were used to assess the association of individual cytokines and the cytokine profiles with outcome via unadjusted and IPS-adjusted hazard ratios (HR). Results: Twelve cytokines (EGF, FGFb, GCSF, HGF, IL-6, IL-8, IL-12, IL-2R, IP-10, MIG, TNFa and VEGF) were significantly (p<0.05) higher in cHL patients than controls; elevated levels of HGF, IL-6, IL-2R, IP-10 and MIG were all associated with poorer event-free survival (EFS). Only IL-2R (p=0.002) and IL-6 (p<0.001) were independently prognostic. Patients with increased IL-6 and IL-2R had a significantly higher risk of early relapse and death, a finding that remained significant even after IPS-based risk stratification. While elevated IL-6 and IL-2R correlated with the IPS, sCD30 and TARC levels, the 2-cytokine model remained independently predictive of prognosis. Conclusions: Elevated pretreatment serum cytokines are associated with increased disease relapse and inferior survival in cHL. Thus, the pretreatment cytokine profile, particularly serum levels of IL-6 and IL-2R, may be used to identify cHL patients at high risk for early disease relapse. PMID:24141626

    Aberrant somatic hypermutation (SHM) has been identified as a mechanism for genomewide instability in diffuse large B-cell lymphoma (DLBCL). To assess whether aberrant SHM plays a role in the molecular pathogenesis of Hodgkin lym- phoma (HL), we investigated microdis- sected neoplastic cells of nodular lympho- cyte-predominant HL(NLPHL; n 10) and classic HL (cHL; n 9) for the presence of mutations

    The diagnosis of nodular sclerosing classical Hodgkin lymphoma (NSCHL) by fine-needle aspiration (FNA) biopsy has historically been a diagnostic challenge due to the usual paucicellularity of the specimen. This case report, and other previously published reports, suggests that there is another facet to the potentially challenging diagnosis of this particular variant of Hodgkin lymphoma (HL): the presence of suppurative-necrotizing changes mimicking an infectious etiology. The patient presented here underwent FNA biopsy of an acutely enlarged supraclavicular lymph node and cytologic smears showed marked acute inflammation in a background of necrosis. A diagnosis of infectious suppurative lymphadenitis was made at that time. After a negative infectious work-up with infectious disease consultation, an excisional biopsy was performed and the patient was definitively diagnosed with NSCHL. The presence of neoplastic Hodgkin and Reed-Sternberg cells in the purulent exudate was minimal and only appropriately identified after retrospective review. This particular subtype of classical HL represents a potential pitfall in FNA biopsy cytology. Consequently, the cytopathologist and surgeon should always consider this entity in the differential diagnosis of a suppurative, lymphadenitis-like aspirate, and pursue repeat FNA or an excisional biopsy if there is any clinical index of suspicion.

    The Hodgkin’s Lymphoma Committee of the Lymphoma Study Association (LYSA) gathered in 2012 to prepare guidelines on the management of transplant-eligible patients with relapsing or refractory Hodgkin’s lymphoma. The working group is made up of a multidisciplinary panel of experts with a significant background in Hodgkin’s lymphoma. Each member of the panel of experts provided an interpretation of the evidence and a systematic approach to obtain consensus was used. Grades of recommendation were not required since levels of evidence are mainly based on phase II trials or standard practice. Data arising from randomized trials are emphasized. The final version was endorsed by the scientific council of the LYSA. The expert panel recommends a risk-adapted strategy (conventional treatment, or single/double transplantation and/or radiotherapy) based on three risk factors at progression (primary refractory disease, remission duration < 1 year, stage III/IV), and an early evaluation of salvage chemosensitivity, including 18fluorodeoxy glucose-positron emission tomography interpreted according to the Deauville scoring system. Most relapsed or refractory Hodgkin’s lymphoma patients chemosensitive to salvage should receive high-dose therapy and autologous stem-cell transplantation as standard. Efforts should be made to increase the proportion of chemosensitive patients by alternating non-cross-resistant chemotherapy lines or exploring the role of novel drugs. PMID:23904236

    The infused autograft lymphocyte to monocyte ratio (A-LMR) as a surrogate marker of host immunity (ie, absolute lymphocyte count) and CD14+ HLA-DRlow/neg immunosuppressive monocytes (ie, absolute monocyte count) is a prognostic factor for patients with diffuse large B-cell lymphoma after autologous peripheral hematopoietic stem cell transplantation (APHSCT). Thus, we set out to investigate if A-LMR can also affect survival post-APHSCT in classical Hodgkin lymphoma. From 1994 to 2012, 183 patients with classical Hodgkin lymphoma who underwent APHSCT were studied. The patients were randomly divided into a training set (n=122) and a validation set (n=61). The receiver operating characteristic and area under the curve identified an A-LMR ?1 as the best cut-off value and validated by the k-fold cross-validation in the training set. Multivariate analysis showed A-LMR to be an independent prognostic factor for survival in the training set. Patients with an A-LMR ?1.0 experienced a superior overall survival (OS) versus patients with an A-LMR <1.0 (median OS not reached versus 40.4 months, 5-year OS rates of 86% [95% CI 72–93] versus 43% [95% CI 28–58], P<0.0001, respectively) in the training set. In the validation set, an A-LMR ?1 showed a median OS of not reached versus 41.4 months for an A-LMR <1, 5-year OS rates of 90% (95% CI 73–97) versus 48% (95% CI 28–68; P<0.0001). A-LMR provides a platform to engineer an autograft versus tumor effect to improve clinical outcomes in patients with classical Hodgkin lymphoma undergoing APHSCT. PMID:25674021

  16. The response of a classical Hodgkin–Huxley neuron to an inhibitory input pulse

    2010-01-01

    A population of uncoupled neurons can often be brought close to synchrony by a single strong inhibitory input pulse affecting all neurons equally. This mechanism is thought to underlie some brain rhythms, in particular gamma frequency (30–80 Hz) oscillations in the hippocampus and neocortex. Here we show that synchronization by an inhibitory input pulse often fails for populations of classical Hodgkin–Huxley neurons. Our reasoning suggests that in general, synchronization by inhibitory input pulses can fail when the transition of the target neurons from rest to spiking involves a Hopf bifurcation, especially when inhibition is shunting, not hyperpolarizing. Surprisingly, synchronization is more likely to fail when the inhibitory pulse is stronger or longer-lasting. These findings have potential implications for the question which neurons participate in brain rhythms, in particular in gamma oscillations. PMID:20387110

    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.

    Although specific microRNA (miRNA) signatures in classical Hodgkin lymphoma (cHL) have been proposed, their relationship with clinical outcome remains unclear. Despite treatment advances, a substantial subset of patients with advanced cHL are refractory to standard therapies based on adriamycin and its variants. Global miRNA expression data of 29 advanced cHL patients and five cHL-derived cell lines were used to identify profiles from Hodgkin-Reed-Sternberg (HRS) cells and their non-tumoural microenvironment. A cHL-miRNA signature was identified with 234 miRNAs differentially expressed. A subset of these miRNAs was associated with outcome and selected for study in an independent set of 168 cHL samples using quantitative reverse transcription polymerase chain reaction. Multivariate Cox regression analyses including cross-validation with failure-free survival (FFS) as clinical endpoint revealed a miRNA signature with MIR21, MIR30E, MIR30D and MIR92B* that identified two risk-groups with significant differences in 5-year FFS (81% vs. 35.7%; P < 0.001). Additionally, functional silencing of MIR21 and MIR30D in L428 cells showed increased sensitivity to doxorubicin-induced apoptosis, pointing towards abnormalities of mitochondrial intrinsic and TP53-CDKN1A pathways as related to miRNA deregulation in cHL. These results suggest that clinical outcome in cHL is associated with a specific miRNA signature. Moreover, functional analyses suggest a role for MIR21 and MIR30D in cHL pathogenesis and therapeutic resistance. PMID:23725219

    We present a case of classical Hodgkin's lymphoma (HL) co-occurring with histological features of Castleman's disease (CD). A 25-year-old man presented with left supraclavicular and axillary lymph node swelling and mediastinal mass. Using an initial biopsy specimen from left axillary lymph node, a tentative diagnosis of multicentric CD of plasma cell type was made. The serum level of interleukin-6 (IL-6) was elevated. The patient was treated with immunosuppressive therapy containing tocilizumab (TCZ). Shrinkage of mediastinal mass and axillary lymph nodes was seen; however, swelling of his left axillary lymph nodes reemerged, even after therapy with TCZ. A second left axillary lymph node biopsy was performed and a diagnosis of nodular sclerosis of classical HL without histologic features of CD was made. The initial biopsy specimen was re-examined, and scattered CD30+ Hodgkin/Reed-Sternberg cells were found in the interfollicular area. Interestingly, Hodgkin/Reed-Sternberg cells and surrounding reactive cells in both lymph nodes were stained with anti-IL-6 antibody. We emphasize that biopsy specimens with HL involvement may also have histologic features reminiscent of those seen in CD. To our knowledge, this is the first report to provide a detailed description of this pathology, including a survey of IL-6 and clinical course upon treatment with TCZ. PMID:23359301

    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

    Interleukin-7 (IL-7) is a pleiotropic cytokine acting mainly on cells of the hematolymphoid system. In vitro studies have shown enhanced proliferation of acute lymphoblastic leukemia cells in response to IL-7. On the other hand, tumor cell lines transfected with a functioning IL-7 gene and subsequently transplanted into mice resulted in a prominent inflammatory infiltrate and reduced tumorigeneicity. These data suggest an important role of this cytokine in the pathophysiology of lymphoid neoplasms. Because little is known about the in vivo expression of this cytokine in various neoplastic and nonneoplastic lesions of the lymphoid system, we examined frozen and paraffin-embedded tissue samples of normal, reactive, and malignant lymphoid lesions using in situ hybridization with a 35S-labeled RNA probe specific for IL-7. Tumor cells of nodular sclerosing and mixed cellularity type of Hodgkin's disease displayed IL-7-specific signals in 24 of 31 cases. Among reactive lesions, only thymic tissue showed labeling within both cortex and medulla (4 of 7 cases), whereas in tonsils clear-cut IL-7-specific signals could not be found. Tissues infiltrated by B-type chronic lymphocytic leukemia or T- or B-type lymphoblastic lymphoma showed cytokine-specific signals in only one case of lymphoblastic lymphoma in rare reactive cells. In conjunction with the finding of elevated levels of IL-7 in the serum of many patients with Hodgkin's disease, our data suggest an important role of this cytokine in the pathogenesis of Hodgkin's disease. The prominent reactive infiltrate observed in most cases of Hodgkin's disease could be a consequence of elevated local levels of this cytokine as similar infiltrates are also observed in tumors in mice resulting from injection of tumor cell lines transfected with a functioning IL-7 gene.

    A recent study observed that numerical chromosome abnormalities in Hodgkin's disease (HD) are detected not only in morphologically abnormal Hodgkin/Reed-Sternberg cells, but also in a fraction of morphologically normal cells. However, the phenotypic constitution of these genetically abnormal, morphologically normal cells and their relationship to the malignant Hodgkin/Reed-Sternberg cells could not be established in the earlier cases studied, because of the low frequency of these cells. The present study investigated two cases of classical Hodgkin's disease containing a relatively large population of such apparently normal cells with aberrant chromosome copy numbers. The phenotype and their position within the developmental route of the malignant compartment were examined by a combined in situ hybridization and immunocytochemistry approach. Numerical abnormalities for chromosome 1 in one case and for chromosomes X, Y, and 1 in the other case were observed not only in CD30-positive Hodgkin/Reed-Sternberg cells, but also in CD30-negative, morphologically normal cells. It was shown that these genetically aberrant cells expressed the B-cell antigen CD19, thus confirming their B-cell nature. These studies indicate a relationship between the genome aberrations in these genetically abnormal, morphologically normal B-cells and the Hodgkin/Reed-Sternberg cells, suggesting that they are progenitor cells of the malignant cell fraction.

    In Western countries, the age distribution of Hodgkin lymphoma (HL) follows a characteristic bimodal curve showing an early and a late peak at approximately 35 and 70 yr, respectively. Furthermore, the presence of latent Epstein-Barr virus (EBV) genome in the Hodgkin Reed-Sternberg cells, the tumour cell population of classical HL (cHL), has been found to have adverse prognostic impact in elderly, but not in younger cHL patients. We have characterised the protein expression in tumour tissue samples from younger (?55 yr) and elderly (>55 yr) cHL patients and correlated the findings with EBV status. Differentially expressed proteins according to patients' age as well as tumoural EBV status belonged to different biological functional domains, such as apoptosis, cytoskeletal organisation, response to oxygen levels and regulation of catabolic/metabolic processes. The differential expression of selected proteins, cytosolic aminopeptidase, heterogeneous nuclear ribonucleoprotein K, serotransferrin and alpha-1-antitrypsin was further validated by Western blot analysis. Discovery-based proteomics characterising biological features distinctive for subsets of cHL patients may be useful for the identification of novel biomarkers with potential therapeutic relevance. An evaluation of the prognostic impact of protein expression pattern in general and individually expressed proteins in particular is warranted. PMID:25307790

    We applied a highly sensitive next-generation sequencing method to identify lymphoma-specific immunoglobulin gene segments in classical Hodgkin lymphoma (CHL) at initial diagnosis or recurrence, and assessed the ability of detecting such lymphoma-specific sequences in peripheral blood (PB). Seventeen CHL cases were tested and lymphoma-specific sequences were identified in 12 of the primary tumour biopsies. In 11 of these patients whose paired PB samples were available, tumour-specific clonotypes were detected in PB in eight patients. This data demonstrates the feasibility of detecting circulating tumour-specific sequences, creating an unprecedented opportunity to optimize the future treatment and monitoring strategies for patients with CHL.

    Rituximab is a patient-paid effective monoclonal-antibody drug for non-Hodgkin lymphoma (NHL). Little is known in China, a country with unequal distribution of wealth and medical insurance systems, about the impact of socioeconomic status (SES) on selecting rituximab therapy in NHL patients. A total of 328 NHL inpatients in 2 public hospitals in Hangzhou were recruited and divided into 2 equal groups: with rituximab therapy and with no rituximab therapy group. Selection and frequency of rituximab therapy increased with duration of education and in urban citizens (P < .01). Officers and businessmen were more likely to use rituximab therapy compared with farmers (P < .01). Patients covered by Urban Employee Basic Medical Insurance were more likely to select rituximab therapy than those insured with Urban-Rural Residents Basic Medical Insurance (P < .01). There was an inequality in provision of rituximab therapy among Chinese NHL patients, and this was associated with differences in SES status. Effective measures are suggested to ameliorate the inequality issue. PMID:23162009

    At present, approximately 20% of Hodgkin lymphomas (HL) are relapsed and refractory, and therapeutic methods including chemotherapy, radiotherapy, and even stem cell transplantation are unsatisfactory. Brentuximab vedotin, composed of CD30 antibody and a chemotherapeutic agent, is a new targeted drug that eradicates tumor cells by binding to the CD30 antigen on their surface. In clinical trials, the response rate and complete remission rate of this drug were 73% and 40%, respectively, for relapsed and refractory HL. Here we report a case of CD30-positive relapsed and refractory HL that was treated with brentuximab. Before the treatment with brentuximab, the patient underwent chemotherapy, radiotherapy, and autologous stem cell transplantation. However, the disease continued to progress, affecting multiple organs and prompting symptoms such as persistent fever. After the treatment with brentuximab, the patient's condition improved. Body temperature returned to normal after 4 days. Lung nodules were reduced in size and number after a single course of treatment, and PET/CT showed partial remission and complete remission after 3 and 6 courses of treatment, respectively. The entire treatment process progressed smoothly, though the patient experienced some symptoms due to chemotherapy, including peripheral neuritis of the limbs, irritating dry cough, and mild increase in aminotransferase. No serious adverse effects were observed. The current general condition of the patient is good; the continuous complete remission has amounted to 6 months. PMID:23544448

    Tumour-associated macrophages (TAMs) have been associated with survival in classic Hodgkin lymphoma (cHL) and other lymphoma types. 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

    Formalin-fixed paraffin-embedded (FFPE) tissues are invaluable sources of biological material for research and diagnostic purposes. In this study, we aimed to identify biological and technical variability in RT-qPCR TaqMan® assays performed with FFPE-RNA from lymph nodes of classical Hodgkin lymphoma samples. An ANOVA-nested 6-level design was employed to evaluate BCL2, CASP3, IRF4, LYZ and STAT1 gene expression. The most variable genes were CASP3 (low expression) and LYZ (high expression). Total variability decreased after normalization for all genes, except by LYZ. Genes with moderate and low expression were identified and suffered more the effects of the technical manipulation than high-expression genes. Pre-amplification was shown to introduce significant technical variability, which was partially alleviated by lowering to a half the amount of input RNA. Ct and Cy0 quantification methods, based on cycle-threshold and the kinetic of amplification curves, respectively, were compared. Cy0 method resulted in higher quantification values, leading to the decrease of total variability in CASP3 and LYZ genes. The mean individual noise was 0.45 (0.31 to 0.61 SD), indicating a variation of gene expression over ~1.5 folds from one case to another. We showed that total variability in RT-qPCR from FFPE-RNA is not higher than that reported for fresh complex tissues, and identified gene-, and expression level-sources of biological and technical variability, which can allow better strategies for designing RT-qPCR assays from highly degraded and inhibited samples.

    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

    The Hodgkin's Lymphoma Committee of the Lymphoma Study Association (LYSA) gathered in 2012 to prepare guidelines on the management of transplant-eligible patients with relapsing or refractory Hodgkin's lymphoma. The working group is made up of a multidisciplinary panel of experts with a significant background in Hodgkin's lymphoma. Each member of the panel of experts provided an interpretation of the evidence and a systematic approach to obtain consensus was used. Grades of recommendation were not required since levels of evidence are mainly based on phase II trials or standard practice. Data arising from randomized trials are emphasized. The final version was endorsed by the scientific council of the LYSA. The expert panel recommends a risk-adapted strategy (conventional treatment, or single/double transplantation and/or radiotherapy) based on three risk factors at progression (primary refractory disease, remission duration < 1 year, stage III/IV), and an early evaluation of salvage chemosensitivity, including (18)fluorodeoxy glucose-positron emission tomography interpreted according to the Deauville scoring system. Most relapsed or refractory Hodgkin's lymphoma patients chemosensitive to salvage should receive high-dose therapy and autologous stem-cell transplantation as standard. Efforts should be made to increase the proportion of chemosensitive patients by alternating non-cross-resistant chemotherapy lines or exploring the role of novel drugs. PMID:23904236

    Classic Hodgkin lymphoma (cHL), a germinal-center related B cell neoplasm in almost all cases, is characterized by scarcity of the neoplastic Hodgkin/Reed-Sternberg (H/RS) cells. Epstein-Barr virus (EBV) has been shown to affect cell cycle and regulation of apoptosis. In total, 95 cases of cHL were studied. Five-micrometer sections were prepared and stained with hematoxylin and eosin and immunohistochemical streptavidin-biotin methods for EBV-LMP-1, COX-2, p53, p16, ki-67 and cleaved caspase-3. In-situ hybridization for EBV encoded RNA was used to confirm the detection of EBV in H/RS. There were 49 nodular sclerosis, 32 mixed cellularity, 8 lymphocyte-rich, and 6 lymphocyte-depleted subtypes in this series of cases. EBV, COX-2, p16INK4A and p53 were detected in 55% (52/95), 64% (61/95), 62% (59/95), and 65% (62/95) of the cases respectively. EBV was detected in 62% (38/61), 70% (41/59), and 69% (43/62) of COX2, p16 and p53 positive cases respectively. On the other hand, EBV-non-infected cases of cHL are associated with 59% (20/34), 69% (25/36), and 73% (24/33) of COX2, p16 and p53 negative cases respectively. In conclusion, EBV infection is associated with the expression of COX-2, p16INK4A and p53. EBV might be the dominant factor in determining the expression of these three proteins. PMID:24294363

    Genes of the major histocompatibility complex (MHC) are valuable makers of adaptive genetic variation in evolutionary ecology research, yet the non-classical MHC genes remain largely unstudied in wild vertebrates. In this study, we have characterized the non-classical MHC class II gene, Egeu-DAB4, in the vulnerable Chinese egret (Ciconiiformes, Ardeidae, Egretta eulophotes). Gene expression analyses showed that Egeu-DAB4 gene had a restricted tissue expression pattern, being expressed in seven examined tissues including the liver, heart, kidney, esophagus, stomach, gallbladder, and intestine, but not in muscle. With respect to polymorphism, only one allele of exon 2 was obtained from Egeu-DAB4 using asymmetric PCR, indicating that Egeu-DAB4 is genetically monomorphic in exon 2. Comparative analyses showed that Egeu-DAB4 had an unusual sequence, with amino acid differences suggesting that its function may differ from those of classical MHC genes. Egeu-DAB4 gene was only found in 30.56-36.56 % of examined Chinese egret individuals. Phylogenetic analysis showed a closer relationship between Egeu-DAB4 and the DAB2 genes in nine other ardeid species. These new findings provide a foundation for further studies to clarify the immunogenetics of non-classical MHC class II gene in the vulnerable Chinese egret and other ciconiiform birds.

    Hodgkin lymphoma (HL) is a curable malignancy which shows a bimodal curve in incidence in economically developed countries; there is a putative association with Epstein-Barr virus. The WHO 2008 classification schema recognises two histological types of HL: the nodular lymphocyte predominant and the "classic" HL. The latter encompasses four entities: nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich. Most patients with HL present with asymptomatic superficial lymphadenopathy. The commonest sites of disease are the cervical, supraclavicular and mediastinal lymph nodes, while sub-diaphragmatic presentations and bone marrow and hepatic involvement are less common. Splenic involvement is usually concomitant with hepatic disease and systemic symptoms; extranodal presentations are quite rare. Systemic symptoms are present in ?35% of cases. The stage of disease is defined according to the Ann Arbor staging system or its Cotswolds variant, and staging work-up includes physical examination, chest X-rays, chest and abdominal CT scan, and bone marrow biopsy. (18)FDG-PET ((18)fluordeoxyglucose positron emission tomography) plays a central role in staging, response assessment and prognosis definition. Classic HL usually spreads by contiguity within the lymphatic tissue network, with a late extension to adjacent and distant viscera. Mortality from HL has been progressively decreasing, as confirmed by the most recent 5-year survival figure of 81%. The list of putative prognostic factors in HL has been increasing, but most factors still require prospective validation. Some of these variables are used to stratify early-stage disease into "favourable" and "unfavourable" categories, with "unfavourable early-stage" being intermediate between "favourable early-stage" and "advanced-stage". ABVD (adriamycin(doxorubicin), bleomycin, vinblastine, dacarbazine) combination chemotherapy followed by involved-field irradiation is the standard treatment for patients with early-stage HL, with a 5-year OS >95%. Several trials assessing less intensive approaches for patients with favourable early-stage HL are ongoing. More intensified combinations, such as the BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine (Oncovin), procarbazine, prednisone) regimen, are being investigated, usually in patients with unfavourable early-stage HL and interim PET+. ABVD is the standard chemotherapy treatment also for patients with advanced disease. Although some evidence suggests that more intensive combinations provide better disease control, the inevitable increased risk of relevant late toxicity worries investigators. Consequently, there has been a shift towards investigating the innovative strategy of a more aggressive schedule for patients with (18)FDG-PET positive results after the first 2 courses of ABVD. High-dose chemotherapy supported by ASCT (autologous stem cell transplantation) is considered the standard of care in patients with HL which has relapsed after, or is refractory to conventional chemoradiotherapy, while allogeneic transplant is a suitable tool for patients with chemorefractory disease and patients failed after ASCT.

    This lymphoma was recognized by Thomas Hodgkin in 1832. In 1865, Samuel Wilks named it Hodgkin disease. Now, the term Hodgkin lymphoma (HL) is acceptable over Hodgkin disease. Since the neoplastic cells of the disease is well-recognized to be a lymphoid cell, especially B lymphocyte. In WHO classification published in 2008, HLs are divided into two entities: Classical HL and nodular lymphocyte predominat HL. The former is composed of four different subtypes: nodular sclerosis (NS), mixed cellularity (MC), lymphocyte rich (LR), and lymphocyte depletion (LD). HL is characterized by the morphological feature comprising a minority of neoplastic cells, Hodgkin/Reed-Sternberg cells and popcorn (LP) cells and a majority of non-neoplastic reactive cells. Antigen receptor gene analyses by prevailing molecular methods and flow cytometry are not appropriate method for the diagnosis of HL, because of small number of neoplastic cells. They are, however, very useful in the differential diagnosis to rule out other lymphomas. Even the present when science progressed, pathological (morphological and immunohistochemical) examination is very worth for diagnosis of HL. PMID:24724402

    In the last few years, there has been a greater understanding of the spectrum and biology of Hodgkin lymphoma. In standard texts, Hodgkin lymphoma is classified as two distinct entities, namely nodular lymphocyte predominant Hodgkin lymphoma and classical Hodgkin lymphoma. However, recent evidence suggests that classical Hodgkin lymphoma is not a single disease. While the mixed cellularity and lymphocyte depleted subtypes may be part of a biologic continuum, the nodular sclerosis subtype has a distinct epidemiology, clinical presentation and histology. Nodular sclerosis Hodgkin lymphoma may also be related to primary mediastinal B-cell lymphoma and mediastinal grey zone lymphomas. We present an update on the pathobiology of Hodgkin lymphoma and discuss these biologic and clinical differences in this review. PMID:19525189

    Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is an uncommon variant of classical Hodgkin lymphoma. It is characterized histologically by presence of lymphohistiocytic cells which have B-cell phenotype, are positive for CD19, CD20, CD45, CD79a, BOB.1, Oct.2, and negative for CD15 and CD30. Patients often present with early stage of disease and do not have classical B symptoms. The clinical behavior appears to mimic that of an indolent non-Hodgkin lymphoma more than that of classical Hodgkin disease. The purpose of the present report is to define the biology of NLPHL, review its clinical presentation, and summarize the available clinical data regarding treatment. PMID:24650975

    Non-Hodgkin's lymphomas are a group of neoplasms that originate from the cells of the lymphoreticular system. Forty percent of non-Hodgkin's lymphomas arise from extra nodal sites. Non-Hodgkin's lymphomas detected primarily in the bone are quite rare, but among jaw lesions, they are more frequently present in the maxilla than in the mandible. There are no classical characteristic clinical features of lymphomas involving the jaw bones. Swelling, ulcer or discomfort may be present in the region of the lymphoma, or it may mimic a periapical pathology or a benign condition. Extranodal non-Hodgkins lymphoma of the maxilla could present as one of the early manifestation of detrimental diseases. Clinically these types of lymphoma can mimic an inflammatory endo-periodontal lesion with symptoms of pain and local discomfort. The greater the delay in diagnosis subsequently worsens the prognosis. A case of maxillary non-Hodgkin's lymphoma with an unusual presentation is discussed. PMID:22639517

    After a median observation time of 4,5 years, 440 patients with Hodgkin's lymphoma stage I-IV to the Ann Arbor classification were treated with radiotherapy (2200 lymph areas) and ABVD (n=204) or BEACOPP (n=117) or CEA/ABVD (lomustine, etoposide, adriamycine, bleomycine, vinblastine and dacarbacine; n=119) regimens in 1995-2012. Correct allocation of groups with "CR or PR ?80%" and "PR: 0-79%", after first-line chemotherapy, is extremely important for following RT planning. Adaptation of patients with Hodgkin's lymphoma can take place only after successful treatment, the probability of relapse and fear of repeated courses strongly interfere with this process, especially in the first years after its closure. Duration of remission period, especially in young people, is no less important than the criteria for overall survival. It is impossible to build recommendations for treatment for Hodgkin's lymphoma, based only on long-term survival rates. Importance of radiotherapy in reducing the number of relapses is undeniable, so the idea that the development of the role of chemotherapy in the treatment of the ray method Hodgkin's lymphoma gradually becomes secondary is in serious doubt. Our findings suggest the importance of both maintaining a high disease-free survival and reducing long-term complications in designing treatments of Hodgkin's lymphoma. PMID:26016145

    Although it is difficult in fully clarifying its mechanisms and effects, Deqi still can be considered as an instant “sign” of acupuncture response of the patient and acupuncturist, which has a significant value in clinic and research. This paper aims to take a history trace to the development of Deqi theory, understand the connotation of Deqi based on Chinese medicine theory, and establish an evaluation methodology accordingly. We believe that Deqi is not only the needling sensation, but also the perception of changes of qi? flowing of the patient elicited by needling on acupoints. The signs of Deqi include the patient's subjective perception (needling sensation), the objective physiological changes (common referred to the skin redness around the acupoints and the response of brain), and the acupuncturists' perception. Although Deqi is essential for attaining the effect, it may not be the necessary sign of the ideal efficacy. It is found that the characteristics of Deqi sensations, Deqi's intensity, time duration, and the propagation will all affect the efficacy. Thus, acupuncturists should pay attention to elicit and control Deqi state, which is also the key point in modern research on the therapeutic implications of Deqi. PMID:24302968

The revised lymph node histopathological examination revealed nodular sclerosis classical Hodgkin's lymphoma associated with abundant tuberculosis-mimicking granulomatous reaction. The diagnosis may be difficult due to similarities in clinical course, laboratory tests and imaging. The morphology of Hodgkin-Reed-Sternberg cells and the immunohistochemical profile are the most helpful in differential diagnosis. In cases where granulomas coexist with negative acid-fast staining, pathologists should always recommend evaluation of further and broader diagnostic procedures to exclude Mycobacterium tuberculosis infection.

    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

    Chinese herbalism dates back to 2852 B.C. More than 2,600 herbs and thousands of herbal formulae are used to treat illness. Classical theories of Chinese medicine are integrated with the Taoist philosophy, whereby the universe is composed of two basic forces: a positive one called yang, and a negative one called yin. Illness is thought to occur when there is too much yang (tonification) or too much yin (sedation) in the body and herbal medicines are therefore intended either to tonify or to sedate the body so that balance is restored. Since 1954, some Chinese herbal remedies have been scientifically analyzed and tested. Several have been proven effective in treating a variety of diseases and conditions. PMID:21283498

    A one-step real-time RT-PCR assay using a minor groove binding probe was developed for the specific detection of Chinese wild-type classical swine fever virus (CSFV). The assay detected wild-type CSFV strains representing different genotypes, but did not amplify viral RNA from the Hog Cholera Lipinized Virus (HCLV) vaccine-strain and other porcine viruses. The assay had a detection limit of 10 copies/reaction or 3.0 median tissue culture infective dose/reaction. In comparison to the sequencing nested RT-PCR assay, the sensitivity and specificity of the assay were 98.3% and 94.3%, respectively, when testing 515 veterinary samples. Wild-type CSFV RNA was detected in nasal swabs 2-4 days before detection in serum samples from pigs exposed to infection by contact, and 2-4 days prior to the onset of clinical disease. HCLV RNA remained undetectable in nasal swabs and serum samples from vaccinated pigs. In conclusion, the novel assay described in this study provides a rapid and sensitive method for differentiating between wild-type and the HCLV-strain of CSFV. It could be used for monitoring in CSF outbreak areas or as a screening method for CSFV eradication strategies. PMID:21723883

    Alismatis Rhizoma Decoction (ARD) is a classical Traditional Chinese Medicine (TCM) formula for treatment of vertigo with its long history of successful clinical effect. Since vertigo is a symptom of hyperlipidemia, this study aimed at evaluating the hypolipidemic effect of ARD in hyperlipidemic mice induced by high fat diet (HFD) and investigated the rationality of formula combination of Alismatis Rhizoma (AR) and Atractylodis Macrocephalae Rhizoma (AMR). Compared with control group, hyperlipidemic mice in AR and ARD groups displayed a reduction of the following parameters: body weight, liver and serum total cholesterol, triglyceride concentration, liver and spleen coefficients, activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT); whereas the serum HDL-cholesterol levels were significantly elevated in both AR and ARD groups. AR and ARD treatments significantly down regulated the expressions of 3-hydroxy-3-methylglutharyl-coenzyme A reductase (HMG-CoA reductase) and sterol regulatory element binding factor-2 (SREBF-2). These findings clearly provided evidences that the suppression on biosynthesis of cholesterol in liver may in part contribute to the hypolipidemic effects of ARD and AR. Since no significantly hypolipidemic effect of AMR was observed, the more prominent effect of ARD than that of AR indicated synergistic effects of AR and AMR, and confirmed the rationality of ARD formula.

    Bruton's tyrosine kinase (Btk) is a member of the Tec family of protein tyrosine kinases involved in B cell development and proliferation in neoplastic human lymphoid tissues. We used immunohistochemistry to evaluate a polyclonal anti-Btk antibody on formalin-fixed paraffin-embedded tissue blocks. The tested samples included normal lymphoid tissues, tissue samples of 395 different lymphomas and 14 malignant lymphoid cell lines. Btk was expressed more often in B cell lymphomas than in T cell lymphomas. This correlated well with the results obtained on B cell lymphoma cell lines, which strongly expressed Btk, in contrast to T cell lymphoma cell lines. More than 60% of myelomas expressed Btk. Among Hodgkin lymphomas, the nodular lymphocyte predominant variant was more often positive (14/16) than the classical variant (6/27). Only one out of three Hodgkin lymphoma-derived cell lines showed a few atypical large cells expressing Btk. Btk represents a useful marker to identify B cell non-Hodgkin lymphomas. Furthermore, Btk might help to distinguish the nodular lymphocyte predominant variant of Hodgkin lymphomas from the classical form. Finally, in view of the recently discovered therapeutic potential of Btk inhibitors in lymphoma, we report the pattern of expression of Btk in a large collection of different types of lymphoma.

    The histopathological and fine-needle aspiration (FNA) cytologic diagnosis of Hodgkin lymphoma (HL) is based on demonstration of pathognomonic mononucleated Hodgkin and bi- to multinucleated Reed-Sternberg (HRS) cells among reactive cellular components composed of lymphocytes, benign histiocytes, neutrophils and eosinophils. In the WHO classification, Hodgkins lymphoma is classified as nodular lymphocytic predominant HL (NLPHL) and classical HL which is in turn sub-classified into lymphocyte-rich (LR), mixed cellular (MC), lymphocytic depleted (MC) and nodular sclerosis (NS) types. The sub-classification of classical HL into LR, MC, and LD depends on relative proportions of neoplastic HRS cells and reactive cellular components. Whereas in HL-NS shows a special type of R-S cells called lacunar cells, NLPHL is characterized by popcorn cells. CHL-MC to some extent and other HL subtypes to a large extent may pose diagnostic challenges in the cytologic material. Reed-Sternberg-like cells have been reported in benign lympho-proliferative conditions like reactive hyperplasia and infectious mononucleosis, and certain of non-Hodgkin lymphoma subtypes as well as non-lymphoid malignancies like metastatic carcinoma, melanoma, sarcomas and germ cell tumors. Non-Hodgkin lymphoma subtypes, e.g., anaplastic large cell lymphoma, T-cell-histiocytic-rich B-cell lymphoma, and pleomorphic peripheral T-cell lymphoma, which can be misdiagnosed as Hodgkin lymphoma, need immunohistochemical studies to be differentiated.

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

    Non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) represent a heterogeneous group of malignant lymphoid tumors, which have distinct histological and/or biological characteristics with preferential nodal involvement. However, none of the previous studies have assessed the prevalence of common NHL and HL subtypes at each nodal site of involvement.The aim of our study was to determine the prevalence of HL and NHL subtypes depending on their nodal sites of involvement.We conducted a single-center retrospective study of 938 lymphoma cases diagnosed in the Pathology Department of Toulouse Purpan Hospital in France between 2001 and 2008, taking into account the site that corresponded to the diagnostic biopsy.The most frequent sites were cervical lymph nodes (36.8% of all cases), inguinal lymph nodes (16.4%), axillary lymph nodes (11.9%), and supraclavicular lymph nodes (11%). We found an unexpected association between intraparotid nodes and nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and between inguinal nodes and follicular lymphoma. The risk of having classical Hodgkin lymphoma (CHL) was 15 times greater in patients with mediastinal lymphoma compared to those with other sites of involvement. Regarding HL, nodal and extranodal mediastinal sites and supraclavicular nodes were more likely to be involved by nodular sclerosis Hodgkin lymphoma (NSCHL). In addition, intra-abdominal lymph nodes were more frequently involved by lymphocyte depleted Hodgkin lymphoma compared to inguinal nodes where NLPHL predominated.Our study shows that some lymph node sites have a disproportionate prevalence of specific subtypes of lymphoma. Identifying these sites may aid to diagnose and better elucidate the pathogenesis of these tumors. PMID:26107683

    During 2012 and 2013, several border disease virus (BDV) strains were identified from Chinese goat and sheep herds. At the same time, pigs from the same areas were found to be seropositive to BDV by ELISA, without showing clinical signs (unpublished data). To examine the susceptibility of pigs to the Chinese BDV strains, BDV isolate JSLS12-01, isolated from naturally infected sheep, was used to infect pigs. Antibody responses, viremia, clinical signs and pathological changes of the infected animals were examined. It confirmed that the current BDV strain could infect the domestic pigs, the animals showed viremia during 4 to 14 days post infection (dpi) and sero-conversion from 14dpi; no clinical and pathological changes were observed. In addition, CSFV maternal antibody did not influence BDV infection. Subsequently, pigs were infected with the BDV isolate and vaccinated with Hog cholera lapinized virus (HCLV) 21 days later to determine the effect of BDV infection on antibody induction of CSFV vaccination. The specific CSFV antibody and neutralizing antibody titers of the BDV infected group remained negative after the primary vaccination. Even after the boost vaccination, they were still significantly lower than those of the uninfected groups (p<0.05). These results indicated that BDV infection could down-regulate the antibody responses of CSFV C-strain vaccination. It should be paid attention that BDV prevalence in pig herds and in live vaccines might hamper the vaccination of CSF. PMID:26117151

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).

    Hodgkin’s lymphoma (HL) is a lymphoid neoplasm characterized by Hodgkin’s and Reed-Sternberg (H/RS) cells, which is regulated by CD99. We previously reported that CD99 downregulation led to the transformation of murine B lymphoma cells (A20) into cells with an H/RS phenotype, while CD99 upregulation induced differentiation of classical Hodgkin’s lymphoma (cHL) cells (L428) into terminal B-cells. However, the molecular mechanism remains unclear. In this study, using fluorescence two-dimensional differential in-gel electrophoresis and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS), we have analyzed the alteration of protein expression following CD99 upregulation in L428 cells as well as downregulation of mouse CD99 antigen-like 2 (mCD99L2) in A20 cells. Bioinformatics analysis showed that SEPTIN2 and STATHMIN, which are cytoskeleton proteins, were significantly differentially expressed, and chosen for further validation and functional analysis. Differential expression of SEPTIN2 was found in both models and was inversely correlated with CD99 expression. STATHMIN was identified in the A20 cell line model and its expression was positively correlated with that of CD99. Importantly, silencing of SEPTIN2 with siRNA substantially altered the cellular cytoskeleton in L428 cells. The downregulation of STATHMIN by siRNA promoted the differentiation of H/RS cells toward terminal B-cells. These results suggest that SEPTIN2-mediated cytoskeletal rearrangement and STATHMIN-mediated differentiation may contribute to changes in cell morphology and differentiation of H/RS cells with CD99 upregulation in HL.

    Hodgkin's disease (HD) shows rare neoplastic Hodgkin and Reed-Sternberg cells embedded in an abundant reactive infiltrate containing, among other cell types, neutrophilic granulocytes. Interleukin (IL)-8 is chemotactic for neutrophils. The expression of IL-8 was tested by in situ hybridization with 35S-labeled IL-8-specific RNA probes on 38 cases of HD. Reactive lesions, non-Hodgkin's lymphomas of B and T phenotype, and Langerhans cell histiocytosis served as controls. IL-8 expression was observed in Hodgkin and Reed-Sternberg cells in 3 of 33 cases of classical HD and in reactive cells in 20 of 33 HD cases as evidenced by combined isotopic in situ hybridization and immunohistology for the demonstration of cell-type-characteristic antigens or enzyme histochemistry for chloroacetate esterase. IL-8-positive cells were more numerous in cases of nodular sclerosing HD as compared with the mixed cellularity histotype (P = 0.01). The number of IL-8-positive cells and the density of neutrophils were positively correlated (P < 0. 01). In 5 cases of lymphocyte-predominant HD, IL-8 expression was not displayed. Non-Hodgkin's lymphoma cases contained IL-8 transcripts only in 1 of 23 cases in sparse reactive cells. In 4 of 7 cases of Langerhans cell histiocytosis, IL-8-specific signals were displayed in S100-negative cells. In conclusion, IL-8 expression in HD is largely confined to reactive cells and associated with infiltration by neutrophils. Elaboration of other cytokines by Hodgkin and Reed-Sternberg cells and reactive cells may explain the frequent expression of this cytokine in HD, particularly in the nodular sclerosing type.

    Hodgkin Lymphoma HL can be cured in the large majority of younger patients, but prognosis for older patients, especially those with advanced-stage disease, has not improved substantially. The percentage of HL patients aged over 60 ranges between 15% and 35%. A minority of them is enrolled into clinical trials. HL in the elderly have some specificities: more frequent male sex, B-symptoms, advanced stage, sub diaphragmatic presentation, higher percentage of mixed cellularity, up to 50% of advanced cases associated to EBV. Very old age (>70) and comorbidities are factor of further worsening prognosis. Like in younger patients, ABVD is the most used protocol, but treatment outcome remains much inferior with more frequent, severe and sometimes specific toxicities. Few prospective studies with specific protocols are available. The main data have been published by the Italian Lymphoma Group with the VEPEMB schedule and the German Hodgkin Study Group with the PVAG regimen. Recently, the Scotland and Newcastle Lymphoma Study Group published the SHIELD program associating a prospective phase 2 trial with VEPEMB and a prospective registration of others patients. Patients over 60y with early-stage disease received three cycles plus radiotherapy and had 81% of 3-year overall survival (OS). Those with advanced-stage disease received six cycles, with 3-year OS of 66%. The role of geriatric and comorbidity assessment in the treatment’s choice for HL in the elderly is a major challenge. The combination of loss of activities of daily living combined with the age stratification more or less 70y has been shown as a simple and effective survival model. Hopes come from promising new agents like brentuximab-vedotin (BV) a novel antibody-drug conjugate. The use of TEP to adapt the combination of chemotherapy and radiotherapy according to the metabolic response could also be way for prospective studies. PMID:25045458

    Hypotension is an extremely rare manifestation of Hodgkin lymphoma. We report the case of a patient who presented with new onset hypotension and was diagnosed with urosepsis and septic shock requiring pressor support for maintaining his blood pressure. computed tomography (CT) scan of abdomen showed liver lesions, which were new on comparison with a CT abdomen done 3 weeks back. Biopsy of the liver lesions and subsequently a bone marrow biopsy showed large atypical Reed-Sternberg cells, positive for CD15 and CD 30 and negative for CD45, CD3 and CD20 on immuno-histochemical staining, hence establishing the diagnosis of Hodgkin lymphoma. The mechanism involved in Hodgkin lymphoma causing hypotension remains anecdotal, but since it is mostly seen in patients with advanced Hodgkin lymphoma, it is hypothetically related to a complex interaction between cytokines and mediators of vasodilatation. Here we review relevant literature pertaining to presentation and pathogenesis of this elusive and rare association. PMID:25317321

    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. PMID:23999613

    Cytomegalovirus infection related changes frequently remain masked by local symptoms of tumor invasion or therapeutic side effects in cancer patients. The spectrum of cytomegalovirus manifestations, however, can be highly varied and may contribute to the failure of different organs with fatal outcome. The case of a 29-year-old female patient is presented who obtained polychemotherapy and allogenic stem cell transplantation following the diagnosis of classical Hodgkin's disease. Despite intensified treatment, only partial response could be achieved and the outcome of the disease was death. Postmortem examination revealed regressive lymph node infiltration as well as nodular liver and spleen manifestations of classical Hodgkin's disease. In addition, parenchymal tissues (lung, kidneys, small intestine, liver, pancreas and ovaries) showed the classical morphology of widespread cytomegalovirus infection. Bilateral enlargement of the ovaries was caused by a partially necrotic giant cell proliferation in the subepithelial cortex. CD30-negativity and cytomegalovirus antigen positivity of the large atypical cell infiltrate supported the diagnosis of cytomegalia oophoritis with morphological overlap between cytomegalovirus-infected giant cells and residual Hodgkin-Reed-Sternberg cells. Further to the cytopathic effect in multiple organs, significant hemophagocytosis was also observed in the spleen, liver and bone marrow. In summary, active cytomegalovirus infection may be a major cause of multi-organ failure in the immunosuppressed oncohematological patient. Careful postmortem analysis demonstrated both the activity of the viral infection and the efficacy of the anti-viral treatment, when applied. PMID:22564287

    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

    Alzheimer's disease (AD) is the most common form of dementia and lacks disease-altering treatments. Fumanjian (FMJ), a famous classic Chinese herbal prescription for dementia, was first recorded in the Complete Works of Jingyue during the Ming Dynasty. This study aimed to investigate whether FMJ could prevent cognitive deficit and take neuroprotective effects in A?1–40-induced rat model through apoptotic signaling pathway. AD model was established by bilateral injection of A?1–40 into hippocampus in rat. All rats were tested for their capabilities of spatial navigation and memorization by Morris water maze. Apoptosis was tested using TUNEL staining in hippocampus neuronal cells; RT-PCR tested expression of Bcl-2 and Bax mRNA; western blotting tested protein level of cleaved caspase-3. After 14 days of treatment, FMJ significantly improved the escape latency and enhanced platform-cross number compared with the A?1–40-injected group (P < 0.05 or P < 0.01). FMJ also significantly decreased number of TUNEL-positive neuronal apoptosis and the expressions of Bax and cleaved Caspase-3 and increased the expression of Bcl-2 (P < 0.01) compared with AD model group. In conclusion, FMJ exerts a protective effect against A?1–40-induced learning and memory deficits and neuronal apoptosis, suggesting that FMJ could be used as a potential therapeutic formula for AD.

    Importance of the field The treatment of Hodgkin lymphoma (HL) with the use of radiotherapy and systemic chemotherapy has been one of the success stories of modern oncology. HL therapy has been the paradigm for the systematic evaluation of different curative modalities resulting in cure for the majority of patients. The current focus is on designing initial therapeutic strategies which retain efficacy and minimize long-term toxicity. Appropriate use of pathologic, clinical, biologic and radiologic prognostic factors in identification of aggressive HL is paramount in designing a successful therapeutic strategy. Areas covered in this review This review addresses the current and future use of prognostic tools, including PET scanning and other biomarkers, in identifying patients with aggressive HL with reference to publications from the last two decades. The current standard approaches with the use of combined modality therapy and systemic chemotherapy as well as the promising role of future response-adapted strategies is reviewed. What the reader will gain The reader will obtain a comprehensive review of risk assessment strategies as well as current and investigational therapeutic approaches in the management of HL. Take home message In HL, appropriate utilization of risk assessment strategies is required to maximize therapeutic outcomes while minimizing toxicity, especially long-term toxicity. Response-adapted therapy utilizing PET has the potential to profoundly improve the therapeutic landscape in HL. PMID:21050034

    Paraneoplastic neurological syndromes (PNSs) rarely associate with Hodgkin lymphoma (HL) and non-HLs (NHLs). Except for paraneoplastic cerebellar degeneration (PCD) in HL and dermato/ polymyositis in both HL and NHL, other PNSs are uncommon and have only been reported as isolated case reports or short series. There are several important differences in PNSs when occurring in association with HL and NHL compared with those associated with solid tumors. First, some PNSs such as sensory neuronopathy or Lambert-Eaton myasthenic syndrome rarely occur in lymphomas, whereas others, such as granulomatous angiitis, are only described in HL. Second, onconeural antibodies are absent in most PNSs associated with lymphomas with the exceptions of Tr (?/notch-like epidermal growth factor-related receptor) in PCD and mGluR5 in limbic encephalitis (LE). The antigens recognized by these antibodies are not expressed in lymphoma cells, suggesting the tumor itself does not trigger the PNS. Third, unlike patients with solid tumors in patients with lymphoma, the PNSs often develops at advanced stages of the disease. Furthermore, the type and frequency of PNSs are different between HL and NHL; whereas LE and PCD occur almost exclusively in patients with HL, sensorimotor neuropathies and dermatomyositis are more frequent in NHL.

Except for paraneoplastic cerebellar degeneration (PCD) in HL and dermato/ polymyositis in both HL and NHL, other PNSs are uncommon and have only been reported as isolated case reports or short series. There are several important differences in PNSs when occurring in association with HL and NHL compared with those associated with solid tumors. First, some PNSs such as sensory neuronopathy or Lambert-Eaton myasthenic syndrome rarely occur in lymphomas, whereas others, such as granulomatous angiitis, are only described in HL. Second, onconeural antibodies are absent in most PNSs associated with lymphomas with the exceptions of Tr (?/notch-like epidermal growth factor-related receptor) in PCD and mGluR5 in limbic encephalitis (LE). The antigens recognized by these antibodies are not expressed in lymphoma cells, suggesting the tumor itself does not trigger the PNS. Third, unlike patients with solid tumors in patients with lymphoma, the PNSs often develops at advanced stages of the disease. Furthermore, the type and frequency of PNSs are different between HL and NHL; whereas LE and PCD occur almost exclusively in patients with HL, sensorimotor neuropathies and dermatomyositis are more frequent in NHL.

    Hodgkin and Reed-Sternberg cells are considered to represent the malignant fraction in Hodgkin's disease. Several studies have shown that the Hodgkin and Reed-Sternberg cells are chromosomally abnormal, but genetic data about the morphologically normal cell population in Hodgkin's disease are very limited. This latter cell population has therefore been examined for chromosomal aberrations, using the in situ hybridization (ISH) procedure, making use of DNA probes for chromosomes 1, 7, 8, 9, 11, 12, 15, 17, and 18. Nuclei were isolated from freshly frozen (10 cases) and paraffin-embedded (16 cases) biopsy samples and 1000 nuclei per case were evaluated. The cases of Hodgkin's disease were compared with reactive lymph nodes, which show aberrant chromosome copy numbers in less than 1 per cent of the cells. Using strict scoring criteria, nuclei in the tumour were found to show an abnormal genotype, in the range of 1-12 per cent, with trisomies occurring most frequently. No characteristic numerical chromosome abnormality was observed. ISH on 4 microns thick paraffin sections of six cases of Hodgkin's disease revealed numerical aberrations for chromosome 1 in cells which appeared to be morphologically normal. The genomically abnormal nuclei did not differ in morphology or size from the nuclei of morphologically normal cells, but differed considerably in size when compared with the nuclei of Hodgkin/Reed-Sternberg cells after the ISH procedure. Three of these six cases revealed a population of apparently normal cells with an aberrant copy number which differed notably from the fraction observed in reactive lymph nodes. It is concluded, therefore, that a subset of morphologically normal cells, next to the Hodgkin/Reed-Sternberg cells, are chromosomally aberrant and may participate in the malignant cell fraction of Hodgkin's disease.

    Children with Hodgkin Lymphoma (HL) routinely undergo surveillance computed tomography (CT) imaging for up to 5 years post-therapy (Rx), resulting in increased cost and radiation exposure without clear benefit. A number of recent studies have demonstrated that routine surveillance imaging, by CT, positron emission tomography (PET)/CT, as well as other imaging techniques, may be over-utilized for routine surveillance of patients with Hodgkin Lymphoma, and-in addition to contributing to increased cost and radiation exposure-show no clear survival benefit. The purpose of this review is to summarize recent data evaluating routine surveillance imaging and its role in detecting disease relapse in patients with Hodgkin Lymphoma. PMID:23832681

    The serum ferritin concentration is increased in both acute myeloblastic leukaemia and Hodgkin's disease. In acute leukaemia the mean concentration is about ten times the normal level and is associated with a high concentration of transferrin-bound iron. In Hodgkin's disease abnormal ferritinaemia is associated with a low concentration of transferrin-bound iron and appears to result from a block of reticuloendothelial iron release. Increased concentrations of circulating ferritin have also been observed in a few cases of chronic leukaemia and myelomatosis. PMID:4511989

    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.

    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.

    Background: Most Hodgkin lymphoma (HL) patients present with disease in nodal regions. However, in a small subset, disease develops extranodal sites primarily, such as lung and liver. This study aims to identify the characteristics and outcomes of patients with primary extranodal HL. Methods: A retrospective analysis of patients with HL from 1998 to 2012 was enrolled. We selected 26 HL patients with primary extranodal involvement from 251 previously untreated HL patients. All data analyses were performed with SPSS software version 17.0 and GraphPad Prism 5. Results: We identified 26 patients with primary extranodal HL. Results in the series of young patients, male predominated. Pathologically, the major pathologic types were nodular sclerosis classical HL (NSCHL, 46.2%) and mixed cellularity classical HL (MCCHL, 38.5%). Thirteen patients had early stage (I or II stage). The most commonly primarily extranodal sites were the lung and the stomach and intestine, followed by the liver and bones. Fifteen of 26 received chemotherapy alone and 11 received combination therapy. Finally, primary extranodal HLs in our study have a favorable survival. Furthermore, there was no significant association between the international prognostic score (IPS) and survival in patients with extranodal HL. Conclusion: Our retrospective data in part reflect clinical characteristics of primary extranodal HL in China, and form the basis for further concerning researches. PMID:25197377

    Hodgkin lymphoma (HL) is an uncommon B-cell lymphoid malignancy composed of two distinct disease entities; the more commonly diagnosed classical HL and the rare nodular lymphocyte predominant HL. Nodular sclerosis, mixed cellularity, lymphocyte depletion, and lymphocyte-rich HL are subgroups under the designation of classical HL. An accurate assessment of the stage of disease in patients with HL is critical for the selection of appropriate therapy. Prognostic models that identify patients at low or high risk for recurrence are used to optimize therapy for patients with limited or advanced stage disease and predict their outcomes while reducing the toxicities. Initial therapy for HL patients is based on the histology, anatomical stage and the presence of poor prognostic features. Management of localized HL has shifted from radiation alone to combined modality strategies with brief courses of combination chemotherapy followed by involved-field radiation therapy. Patients with advanced stage disease receive a longer course of chemotherapy commonly without radiation therapy. Clinical trials are being conducted using the early interim response or response at the end of therapy as measured by PET scan to determine treatment. PMID:23769695

    Purpose: Malignant cells from Hodgkin’s disease have been reported to be defective in regulation of NF-?B activity. Ionizing radiation is known to activate NF-?B, and it has been suggested that this pathway may protect cells from apoptosis following exposure to radiation and other therapeutic agents. Defective NF-?B regulation in Hodgkin cells could therefore dictate the response of this disease to

    Hodgkin's lymphoma complicating chronic ulcerative colitis is extremely rare. We report a case of extranodal Hodgkin's lymphoma involving rectosigmoid in a patient of chronic ulcerative colitis on long-term azathioprine. A 67-year-old man presented with extensive ulcerative colitis, on follow-up since September 2005. He received long-term steroids, mesalamine and azathioprine. Serial surveillance colonoscopic examinations and colonic biopsies were performed. Surveillance colonoscopy performed 8?years after the onset of disease showed multiple deep ulcers and nodular masses involving the rectum and sigmoid colon. Histological examination of rectosigmoid biopsies showed classic Hodgkin's disease. Azathioprine was withdrawn. He received mechlorethamine, vincristine, procarbazine and prednisone (MOPP) chemotherapy protocol and was planned for total colectomy in follow-up. We believe patients with ulcerative colitis on long-term azathioprine should be on vigil for development of lymphomas by protocol surveillance colonoscopic examinations and biopsies. The risk of lymphoma in such patients is small and outweighs the benefits of long-term azathioprine therapy. PMID:24849639

    A 71-year-old woman was admitted because of persistent fever for 2?weeks. A diagnosis of haemophagocytic lymphohistiocytosis (HLH) was made on the basis of persistent high fever, pancytopoenia, hyperferritinaemia, increased soluble interleukin-2 receptor (sIL-2R) levels and histiocytosis and hemophagocytosis in the bone marrow. CT showed neither infection nor lymphadenopathy. After administration of prednisolone, haematological findings improved and the fever resolved; however, the patient developed persistent fever after 6?months. In addition, levels of lactate dehydrogenase and sIL-2R increased again. CT scans revealed diffuse lymphadenopathy, and Hodgkin's lymphoma was diagnosed by lymph node biopsy. Progression of pancytopenia was observed, and bone marrow examination showed a relapse of HLH. After six courses of chemotherapy were given for Hodgkin's lymphoma, complete remission was achieved with no evidence of pancytopenia. Hodgkin's lymphoma may be the underlying cause in HLH cases of unknown aetiology. Hence, the clinical course should be carefully monitored even in the absence of lymphadenopathy. PMID:23761512

    PURPOSE We aimed to evaluate the role of fluorine-18 fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) involving care-dose unenhanced CT to detect extranodal involvement in patients with non-Hodgkin and Hodgkin lymphoma. MATERIALS AND METHODS Lymphoma patients (35 Hodgkin lymphoma, 75 non-Hodgkin lymphoma) who were referred for 18F-FDG PET-CT imaging, following a diagnostic contrast-enhanced CT (CE-CT) performed within the last month, were included in our study. A total of 129 PET-CT images, and all radiologic, clinical, and pathological records of these patients were retrospectively reviewed. RESULTS In total, 137 hypermetabolic extranodal infiltration sites were detected by 18F-FDG PET-CT in 62 of 110 patients. There were no positive findings by CE-CT that reflected organ involvement in 40 of 137 18F-FDG-positive sites. The ? statistics revealed fair agreement between PET-CT and CE-CT for the detection of extranodal involvement (?=0.60). The organs showing a disagreement between the two modalities were the spleen, bone marrow, bone, and thyroid and prostate glands. In all lesions that were negative at CE-CT, there was a diffuse 18F-FDG uptake pattern in the PET-CT images. The frequency of extranodal involvement was 51% and 58% in Hodgkin and non-Hodgkin lymphoma patients, respectively. There was a high positive correlation between the maximum standardized uptake values of the highest 18F-FDG-accumulating lymph nodes and extranodal sites (r=0.67) in patients with nodal and extranodal involvement. CONCLUSION 18F-FDG PET-CT is a more effective technique than CE-CT for the evaluation of extranodal involvement in Hodgkin and non-Hodgkin lymphoma patients. PET-CT has a significant advantage for the diagnosis of diffusely infiltrating organs without mass lesions or contrast enhancement compared to CE-CT. PMID:24412817

    Primary isolated bone marrow disease as a presenting feature of lymphoma is very rare. We describe the case of a Chinese with isolated bone marrow small B-cell lymphoma as a first manifestation. A 55-year old woman was admitted to our hospital with fever. Her peripheral blood smear and laboratory findings were suggestive of bicytopenia. Bone marrow specimen showed diffusely distributed small-sized lymphocytes. Combined with immunophenotypic and chromosomal analysis, a diagnosis of primary bone marrow B-cell non-Hodgkin's lymphoma was made. The patient was treated with R-CHOP (rituximab and cyclophosphamide, epirubicin, vindesine, and prednisone) regimen for six cycles. She had complete remission and is still alive without relapse. We concluded that primary bone marrow mature small B-cell lymphoma is a rare but distinctive subtype of lymphoma. The prognosis for this entity is poor but rituximab-based treatment is promising for improving its outcomes. PMID:24171336

    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

    Aims: The epidemiological and pathological features of Hodgkin lymphoma (HL) are complex. The Epstein-Barr virus (EBV) is consistently associated with a proportion of cases, and these cases are thought to represent a distinct aetiological subgroup of HL. The aim of the present analysis was to determine the age and sex specific incidence of EBV associated and non-associated HL, analysed separately, using data derived from a population based study–the Scotland and Newcastle epidemiological study of Hodgkin’s disease (SNEHD). This study also provided a unique opportunity to evaluate accuracy in the current diagnosis and classification of HL. Methods: SNEHD analysed consecutive cases of HL diagnosed in the study area between 1993 and 1997. Diagnostic biopsy material was retrieved, EBV status of tumours was determined, and histological review was performed. Results: In total, 622 cases were eligible for the study, and EBV studies and histopathological review were performed on biopsy material from 537 and 549 cases, respectively. Accuracy in the overall diagnosis of HL and classification of nodular sclerosis HL was good, but diagnosis of HL in the elderly and classification of other subtypes was less reliable. One third of classic HL cases were EBV associated, and age specific incidence curves for EBV associated and non-associated cases were distinct. Conclusions: Comparison of age specific incidence curves for EBV associated and non-associated HL supports the hypothesis that these are two distinct aetiological entities. Accuracy in the diagnosis of HL is generally good, but certain subgroups of cases continue to present diagnostic difficulties. PMID:14600123

    Post-transplant lymphoproliferative disorder (PTLD) occurs in 1.2% of pediatric renal transplant patients, and is frequently Epstein-Barr Virus mediated. Hodgkin Lymphoma PTLD is the rarest of the 4 types of PTLDs recognized by the World Health Organization, with an incidence of <4% of all PTLD patients. It has a distinct clinical course and treatment from all other types of PTLD. This is a case of a 16-year-old girl who had a renal transplant in 2000 due to Moya Moya disease. Her first F-18 FDG PET/CT done in 2006 showed mildly FDG-avid mediastinal adenopathy (histologically nonspecific reactive nodes), however in 2009, after presenting with fevers, a repeat PET/CT showed extensive intensely FDG-avid disease. Biopsy of a supraclavicular node identified Hodgkin Lymphoma PTLD. The patient was treated with chemotherapy and reimaged, showing excellent response to therapy. In contrast, classic PTLD is treated by withdrawal of immunosuppression and administration of Rituximab. F-18 FDG PET/CT is known to be very useful in the staging and monitoring of response to therapy in the setting of classic PTLD. In this case, serial F-18 FDG PET/CT scans proved very useful in the evaluation and follow-up of the rare and distinct Hodgkin Lymphoma PTLD subtype. PMID:20706047

    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.

    Non-Hodgkin Lymphoma (NHL) occurs worldwide although there is notable geographical variation in incidence and subtype distribution. These differences are due to a combination of demographic, environmental and other unidentified factors. A dramatic increase in NHL incidence was seen starting around 1970, with subsequent stabilization 10 years ago. Despite this plateau, the number of new cases in many countries will increase significantly in coming years due primarily to aging populations. In the majority of cases, strong risk factors are not identifiable. There is significant epidemiological heterogeneity between NHL subtypes, yet cancer registries have tended to consider NHL as a single entity. This is one of several epidemiological obstacles discussed. PMID:23958141

    Hodgkin lymphoma (HL) associated with Warthin tumor (WT) is extremely rare, accounting for only 3 cases of classical HLs. Here, we report for the first time the occurrence of a nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) involving the lymphoid stroma of a WT of the parotid gland. Pathogenesis of WT is controversial, with both a nodal and a parenchymal possible origin. On the other hand, extranodal involvement by HLs is uncommon. In our case, the coexistence of a WT and of a NLPHL within its stroma and in cervical lymph node emphasizes the importance of a careful evaluation of the lymphoid tissue in WT in order to exclude the possibility of an associated lymphoid malignancy.

  18. Paraneoplastic pruritus presenting with Hodgkin’s lymphoma: a case report

    PubMed Central

    2014-01-01

    Introduction Paraneoplastic pruritus is defined as pruritus that occurs before or during the natural evolution of a hematologic disease. The reported prevalence is 30% in patients with Hodgkin’s lymphoma. The severity of this pruritus has a very negative impact on patients’ quality of life. Very few studies have been made to examine the efficacy of pharmacological treatments for this type of pruritus. One drug that appears to be effective in this respect is off-label aprepitant, a neurokinin 1 receptor antagonist. Case presentation A 20-year-old Caucasian woman presented with lateral neck nodes, sweating, and pruritus and was diagnosed with stage IIB nodular sclerosis Hodgkin’s lymphoma. Throughout this period during the disease the pruritus was ever-present. Improvement was achieved with some of the chemotherapy treatments, but the symptom returned when the various treatments were withdrawn due to disease progression or poor tolerance. In the middle of the seventh year, she was admitted to our hospital with uncontrolled pruritus that resulted in severe lesions due to scratching. In response, aprepitant (off-label) 80mg/day was added to the chemotherapic treatment of the pruritus, after studying the various treatment options. She reported a score of 9 on a visual analogue scale for the pruritus, and a score of 3 on the Eastern Cooperative Oncology Group performance status scale of performance status. After two weeks of treatment with aprepitant, she reported a score of 5 on the visual analogue scale for the pruritus, and this improved to a score of 4 in a month, which allowed her to lead a better quality of life, with an Eastern Cooperative Oncology Group performance status score between 1 and 2. Conclusions Several cases and case series have been reported on the use of aprepitant for paraneoplastic pruritus, but none have referred to its use for Hodgkin’s lymphoma. A prospective study was carried out to evaluate the efficacy of this drug in refractory pruritus secondary to Sezary syndrome, and other authors have studied the effectiveness of aprepitant against pruritus, secondary to biological therapy with erlotinib. In our case report, treatment was started with daily doses of aprepitant 80mg. Pruritus improvement appeared to be attributable exclusively to the administration of aprepitant. PMID:25200537

    The therapeutic approach to relapses in aggressive non-Hodgkin's lymphoma has been changed by high dose chemotherapy and autologous bone marrow graft. In the absence of dramatic improvement following the conditioning regimen, such a procedure should be reserved for patients still sensitive to salvage therapy. Up to 40%-50% of these selected cases can expect prolonged disease-free survival. Autologous bone marrow graft in first remission should only be considered in poor prognosis patients in a carefully randomized study. In Hodgkin's disease, relapses and patients in partial remission after MOPP and ABVD treatment are potential candidates for autologous bone marrow graft. Preliminary results indicate a disease-free survival up to 50%. PMID:2455276

    Four cases of thyroidectomy for suspected thyroid carcinoma after previous irradiation for Hodgkin's or non-Hodgkin's lymphoma are reviewed. The patients ranged in age from 18 to 33 years at the time of thyroid surgery with an average latency period of 12 years (range, 8-20 years) from radiation therapy to thyroidectomy. All patients had a clinically palpable thyroid nodule, and pathologically showed a pattern of multiple adenomatous nodules with cytologic atypia. The microscopic changes were sufficiently striking to cause the primary pathologist to request consultation to rule out thyroid carcinoma in each case. Fine-needle aspiration was performed in one case and suggested a thyroid neoplasm. The pathologic findings are reviewed and distinction of this lesion from thyroid carcinoma is discussed.

    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.

    6 years ago a 60-year-old man had been suffering from chronic diarrhea, weight loss and epigastric pain. Some years before he had developed joint pain, symmetric at both hands and feet. Duodenal biopsy and PCR reaction revealed Whipple's disease. Treatment with Co-trimoxazole for more than 21 months achieved remission. 6 years after diagnosis of Whipple's disease the patient presented with multilocal lymphadenopathy. Malignant Non-Hodgkin-Lymphoma (Centrocytom) stage PS IV b was diagnosed. COP-chemotherapy (Vincristine, Cyclophosphamide, Prednisone) achieved partial remission up to now. Whether the appearance of the malignant lymphoma is a consequence of Whipple's disease or a second neoplastic disease remains to be answered by further epidemiological studies. PMID:11367979

    Classical Hodgkin lymphoma (cHL) is characterized by sparsely distributed Hodgkin and Reed-Sternberg (HRS) cells amid reactive host background, complicating the acquisition of neoplastic DNA without extensive background contamination. We overcame this limitation by using flow-sorted HRS and intratumor T cells and optimized low-input exome sequencing of 10 patient samples to reveal alterations in genes involved in antigen presentation, chromosome integrity, transcriptional regulation, and ubiquitination. ?-2-microglobulin (B2M) is the most commonly altered gene in HRS cells, with 7 of 10 cases having inactivating mutations that lead to loss of major histocompatibility complex class I (MHC-I) expression. Enforced wild-type B2M expression in a cHL cell line restored MHC-I expression. In an extended cohort of 145 patients, the absence of B2M protein in the HRS cells was associated with lower stage of disease, younger age at diagnosis, and better overall and progression-free survival. B2M-deficient cases encompassed most of the nodular sclerosis subtype cases and only a minority of mixed cellularity cases, suggesting that B2M deficiency determines the tumor microenvironment and may define a major subset of cHL that has more uniform clinical and morphologic features. In addition, we report previously unknown genetic alterations that may render selected patients sensitive to specific targeted therapies. PMID:25488972

    Although many studies have revealed the association between cyclooxygenase-2 (COX-2) and carcinogenesis, the association between COX-2 and Hodgkin's lymphoma (HL) remains unknown. We examined the immunohistochemical expression of COX-2, p53, bcl-2, and Ki-67 in 33 patients with HL, and counted microvessels stained with CD34. Hodgkin and Reed - Sternberg (HRS) cells with COX-2 expression were scored as 0 = no staining; 1 = <25% of cells staining; 2 = 25-49%; 3 = 50-75%; and 4 = > or =75%. COX-2 expression was observed in 15 cases of classical HL. Nevertheless, neither accumulation of p53 nor bcl-2 expression was associated with COX-2 expression. The percentage of Ki-67 positive-HRS cells and microvessel density in COX-2 score groups 2-4 were significantly higher than those in score group 0, respectively. We show that COX-2 expression is associated with cell proliferation and angiogenesis in HL. These findings suggest that COX-2 may be a target for therapy in HL. PMID:17064999

    A three-year-old boy presented with an enlarging neck mass. Biopsy demonstrated IgD-positive nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL), which was staged as IIa. The patient received cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with rituximab and had excellent results. NLPHL is a relatively rare disease that is biologically distinct from classic Hodgkin lymphoma (cHL). NLPHL is a B-cell malignancy likely of germinal center origin that has an overall good prognosis and favorable response to treatment. Unlike cHL, NLPHL is ubiquitously CD20-positive. Recent evidence supports the efficacy of targeted anti-CD20 therapy in NLPHL, though prospective data is limited. This case demonstrates several unique features of NLPHL and further supports the use of rituximab in front-line therapy. The clinical characteristics among patients at various ages are discussed with a special focus on the IgD-positive subtype. A thorough literature search demonstrates this to be the youngest patient with NLPHL yet described. PMID:25878913

    Hodgkin lymphoma is caused by a minority population of malignant Hodgkin and Reed-Sternberg (HRS) cells that recruit an abundance of inflammatory cells. The long-term survival of HRS cells among the vast majority of immune cells indicates that they have developed potent immune escape mechanisms. We report that the TNF receptor family member CD137 (TNFRSF9) is expressed on HRS cells, while normal B cells, from which HRS cells are most often derived, do not express CD137. In 48 of 53 cases of classical Hodgkin lymphoma, CD137 was detected on HRS cells. Ectopically expressed CD137 transferred by trogocytosis from HRS cells to neighboring HRS and antigen-presenting cells, which constitutively express the CD137 ligand (CD137L and TNFSF9), became associated with CD137L and the CD137-CD137L complex was internalized. Disappearance of CD137L from the surface of HRS and antigen-presenting cells led to reduced costimulation of T cells through CD137, reducing IFN-? release and proliferation. Our results reveal a new regulatory mechanism for CD137L expression that mediates immune escape by HRS cells, and they identify CD137 as a candidate target for immunotherapy of Hodgkin lymphoma.

    Hodgkin lymphomas (HLs) are neoplasms of large B cells. Two types are recognized: nodular lymphocyte predominant HL (NLPHL) and classical HL (CHL). In both types, there may be morphological and possibly biological overlap with large B-cell lymphomas (LBCLs) of non-HL types. These include nodular sclerosis CHL and primary mediastinal large B-cell lymphoma; CHL rich in lymphocytes and NLPHL; and NLPHL and T-cell/histiocyte-rich LBCL.

    Background The role of dietary factors in the epidemiology of Non-Hodgkin's lymphoma (NHL) remains largely undefined. Dietary habits may play a role in the etiology of NHL by influencing the immune system. Methods Dietary patterns and the risk of NHL were analyzed in a case control study; including 170 NHL cases and 190 controls. All subjects completed a validated food-frequency questionnaire. The dietary pattern was investigated separately and in nine nutritional groups. Crosstab tables were used to estimate the odds ratios (OR), and Ptrend. Results Consumption of highest versus lowest quartile of proteins (OR, 8.088 Ptrend=0.000), fats (OR, 6.17 Ptrend=0.000) and sweets (OR, 8.806 Ptrend=0.000) were associated with a significantly increased NHL risk. The inverse association was found for fresh fruits (OR, 0.117 Ptrend=0.000) and vegetables (OR, 0.461 Ptrend=0.010). Conclusion An association between dietary intake and the risk of NHL is biologically plausible due to immunosuppressive effects of fat and animal proteins, and antioxidant properties of vegetables and fruits.

    Cancer is a life-threatening condition. We describe the case of a 22-yr-old world-class endurance athlete who presented with mild local lymphadenopathy but without any systemic complaints or impaired performance. He was subsequently diagnosed with stage III A (S) Hodgkin's lymphoma. A complete physiological workup before the diagnosis revealed high aerobic capacity. Immediately after six courses of escalated BEACOPP chemotherapy in an identical test setting, aerobic capacity was markedly reduced (-42%), mainly because of a decrease in total hemoglobin mass (-37%), despite maintaining a certain amount of endurance training. Other potentially performance-limiting systems such as heart, lung, or aerobic metabolism did not show any signs of impairment. Two months after chemotherapy, the athlete had recovered his hemoglobin mass, and his aerobic performance was almost back to pretherapy levels. This case illustrates that advanced malignancies can be present in elite athletes without affecting performance, and that aerobic capacity can be regained within a short time after systemic chemotherapy.

    The improved survival rates among patients with Hodgkin's lymphoma over the past few decades have come with increased incidence of second malignancies. One of the major concerns among female survivors is the significantly elevated risk of breast cancer that appears with extended follow-up. In this review, we include the published literature regarding the risk of breast cancer after irradiation for Hodgkin's lymphoma. We also present the possible long-term surveillance strategies and the optimal time to start screening these women. This could potentially help in early detection of secondary breast cancers and consequently improve outcomes. Furthermore, because of prior radiotherapy, the management of the breast cancer among this unique population has been controversial. We discuss the characteristics of breast cancer that occurs after Hodgkin's lymphoma and also treatment options that could be implemented.

    The RAND Corporation has recently added selections from the writings of Albert Wohlstetter to its well known RAND Classics site. Wohlstetter "was a mathematical logician and senior staff member at RAND in the 1950s and 1960s.... His studies led to the 'second-strike' and 'Fail-Safe' concepts for deterring nuclear war. These and other methods reduced the probability of accidental war." At present, 24 selections are available, ranging from 1952 to 1970. More are forthcoming. In addition to Wohlstetter's writings, RAND Classics contains eleven of Paul Baran et al's twelve volume On Distributed Communications (1968), RAND's A Million Random Digits with 100,000 Normal Deviates (1955), and Toward an Ethics and Etiquette for Electronic Mail (1985), by Norman Z.

    The clinical course and biopsy specimens from 515 consecutive non-Hodgkin's lymphoma patients was evaluated retrospectively in an attempt to determine the clinical importance of documented changes in histology over time. Two-hundred and five of these patients has an initial diagnosis of nodular lymphoma and were reviewed for this anaysis. Sixty-three underwent a repeat biopsy greater than 6 mo after initial diagnosis. In 23 patients, these repeat biopsies revealed a change in histology to a diffuse pattern and/or a change to a larger ''histiocytic'' cell type, while repeat biopsies for the other 40 (63%) disclosd persistence of a nodular pattern and no clear change in basic cell type. Progression from nodular lymphoma to diffuse histiocytic, mixed, or undifferentiated types of lymphomas of Rappaport was found in repeate biopsies obtained from 19 patients (30%). Prognosis for survival following a biopsy that demonstrated histologic change was related to the histology demonstrated at the most recent biopsy and to the response to subsequent drug treatment. Survival following repeat biopsy for these 19 patients was significantly shorter than for the 40 patients whose histology remained nodular (p < 0.001). However, attainment of a complete remission with intensive combination chemotherapy was associated with prolonged survival in eight patients and prolonged disease-free survival in one patient. Since prior treatment may compromise the ability to achieve a complete response to chemotherapy in patients with nodular lymphoma who develop an aggressive diffuse histology, the likelihood of histologic progression must be considered in the design of future clinical trials in nodular lymphoma. Histologic progression does not preclude attainment of a complete response to intensive chemotherapy.

    Non Hodgkin's lymphomas (NHL) constitute a heterogeneous group of neoplasm of the lymphoid system. There are many histological subtype of NHL based on WHO classification of hematopoietic and lymphoid neoplasm. This cross-sectional study was carried out in the department of Pathology, Dhaka Medical College, Dhaka from January 2009 to December 2010 to observe the different subtypes of NHL using immunohistochemistry (IHC) with CD3. A total of 50 microscopically diagnosed case of NHL irrespective of age and sex were included in the study. The diagnostic morphologic criteria of each lymphoma subcategory were compiled and diagnosis was made. Mean age of the study subjects were 42.0±19.7 years with range 3-75 years and male female ratio was 1.8:1. Nodal NHL was 66% and extranodal cases were 34%. Maximum number of histolgic subtypes belonged to diffuse large B-cell lymphoma (DLBCL) and male was predominant in all histological subtypes, except peripheral T-cell lymphoma (PTCL). DLBCL was predominant in all B-cell NHL whereas PTCL was predominant in all T-cell NHL. The most childhood patients belonged to lymphoblastic lymphoma. Regarding cell lineage B-cell NHL was more common than T-cell NHL (88% vs. 12%), but high grade pattern was more predominant in T-cell type (83.3% vs. 65.9%). Among 50 study subjects histological (H & E) diagnosis reveals 46 cases as B-cell NHL and 4 as T-cell NHL but IHC confirms 6 cases as T-cell NHL. PMID:25725676

    Rationale Patients with Hodgkin’s Lymphoma (HL) relapsing after hematopoietic stem cell transplant (HSCT) have limited options for long-term cure. We have shown that infused cytotoxic T cells (CTL) targeting Epstein Barr virus (EBV)-derived proteins induced complete remissions in EBV+ HL patients. A limitation of this approach is that up to 70% of relapsed HL tumors are EBV-negative. For these patients an alternative is to target the cancer/testis antigen MAGE-A4 present in EBV antigen-negative HL tumors. Furthermore, epigenetic modification by clinically available demethylating agents can enhance MAGE-A4 expression in previously MAGE-negative tumors. Experimental Design We explored the feasibility of combining adoptive T cell therapy with epigenetic modification of tumor antigen expression. We further characterized MAGE-A4-specific T cell phenotype and function, and examined the effects of the epigenetic-modifying drug decitabine on these T cells. Results Cytotoxic T cells were generated specifically recognizing MAGE-A4 expressed by autologous HL targets and tumor cell lines. Decitabine – previously shown to increase tumor antigen expression in Hodgkin’s Lymphoma – did not compromise MAGE-A4 specific T cell phenotype and function. In patients treated with decitabine, expanded MAGE-A4 specific T cells had a broader anti tumor T cell repertoire consistent with increased antigen stimulation in vivo. Conclusions Adoptive transfer of MAGE-A4 specific T cells, combined with epigenetic-modifying drugs to increase expression of the protein may improve treatment of relapsed Hodgkin’s Lymphoma.

    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

    Primary adrenal lymphoma is rare and constitutes for 3% of extranodal lymphoma cases. Approximately 70% of patients present with bilateral disease and have adrenal insufficiency. Prognosis of primary adrenal lymphoma (PAL) is poor, most of patient die within one year of diagnosis. Moreover, there are no standard treatment protocols on such cases. Patients are generally treated with regimens similar to other nonhodgkin lymphoma which includes surgery, combination chemotherapy and or radiotherapy. We are presenting a successfully treated case of primary diffuse large B cell non Hodgkin lymphoma of adrenal gland in a 57-year-old patient. The patient had unilateral adrenal involvement (left adrenal gland), without adrenal insufficiency and normal Serum lactate dehyrogenase level. The patient was treated with left adrenalectomy followed by combination chemotherapy. Two years after diagnosis and treatment the patient is disease free on clinical and imaging studies.

    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.

    Infectious etiologies have been hypothesized for Hodgkin and non-Hodgkin lymphoma (HL and NHL) in early life, but findings to date for specific lymphomas and periods of susceptibility are conflicting. We conducted the first national cohort study to examine whether season of birth, a proxy for infectious exposures in the first few months of life, is associated with HL or NHL in childhood through young adulthood. A total of 3,571,574 persons born in Sweden in 1973-2008 were followed up through 2009 to examine the association between season of birth and incidence of HL (943 cases) or NHL (936 cases). We found a sinusoidal pattern in NHL risk by season of birth (p?=?0.04), with peak risk occurring among birthdates in April. Relative to persons born in fall (September-November), odds ratios for NHL by season of birth were 1.25 [95% confidence interval (CI), 1.04-1.50; p?=?0.02] for spring (March-May), 1.22 (95% CI, 1.01-1.48; p?=?0.04) for summer (June-August) and 1.11 (95% CI, 0.91-1.35; p?=?0.29) for winter (December-February). These findings did not vary by sex, age at diagnosis or major subtypes. In contrast, there was no seasonal association between birthdate and risk of HL (p?=?0.78). In this large cohort study, birth in spring or summer was associated with increased risk of NHL (but not HL) in childhood through young adulthood, possibly related to immunologic effects of delayed infectious exposures compared with fall or winter birth. These findings suggest that immunologic responses in early infancy may play an important role in the development of NHL. PMID:24752499

    Periodic solutions of the current clamped Hodgkin-Huxley equations (Hodgkin & Huxley, 1952 J. Physiol. 117, 500) that arise by degenerate Hopf bifurcation were studied recently by Labouriau (1985 SIAM J. Math. Anal. 16, 1121, 1987 Degenerate Hopf Bifurcation and Nerve Impulse (Part II), in press). Two parameters, temperature T and sodium conductance gNa were varied from the original values obtained by Hodgkin & Huxley. Labouriau's work proved the existence of small amplitude periodic solution branches that do not connect locally to the stationary solution branch, and had not been previously computed. In this paper we compute these solution branches globally. We find families of isolas of periodic solutions (i.e. branches not connected to the stationary branch). For values of gNa in the range measured by Hodgkin & Huxley, and for physically reasonable temperatures, there are isolas containing orbitally asymptotically stable solutions. The presence of isolas of periodic solutions suggests that in certain current space clamped membrane experiments, action potentials could be observed even though the stationary state is stable for all current stimuli. Once produced, such action potentials will disappear suddenly if the current stimulus is either increased or decreased past certain values. Under some conditions, "jumping" between action potentials of different amplitudes might be observed. PMID:2811393

    2015-01-01

    Background and objectives: Numerous studies have focused on the role of survivin in non-Hodgkin’s lymphomas (NHLs), but evidence regarding the prognostic value of survivin with respect to overall survival (OS) in NHL remains controversial. The aim of this study is to gain a better insight about the direct relationship between survivin expression and patients’ survival statuses. Materials and methods: Relevant publications addressing the association between survivin expression and OS in NHL patients were selected from PubMed, Embase, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database and the Cochrane library. Studies were pooled and summary hazard ratios (HR) were calculated. Sensitivity analyses and publication bias were also conducted. Statistical analysis was performed by STATA 12.0 software. Results: 12 studies met the inclusion criteria. Combined HRs suggested that survivin overexpression had an unfavorable impact on NHL patients’ survival (HR=1.55, 95% CI=1.12-2.13, P=0.008). Subgroup analyses according to the studies categorized by histological type, ethnicity, cutoff scores and follow-up period were also conducted, and all the above analyses supported the stability of the prognostic role of survivin. Conclusion: Our findings suggest that survivin high expression might be a poor prognostic factor for patients with NHL. However, further large scale studies are needed to confirm these findings.

    AIM: To evaluate the morphofunctional characteristics of lymph node cells from patients with Hodgkin's disease by measuring silver stained nucleolar organiser regions (AgNORs). METHODS: Nucleoli in Hodgkin's and Reed-Sternberg (HRS) cells, lymphocytes and prolymphocytes were investigated in cytological smears and histological sections of lymph nodes from 32 patients with Hodgkin's disease, and from 34 patients with reactive lymphadenopathy. According to the Rye histological classification of Hodgkin's disease, three cases were the lymphocyte predominant (LP) type, 14 the nodular sclerosing (NS) type, and 15 the mixed cellularity (MC) type. The investigation was done before treatment, by means of a one step silver staining method. In each case, 50 to 100 HRS cells, lymphocytes, and prolymphocytes were evaluated to determine the mean numbers of nucleoli and AgNORs per nucleus. The nonparametric Wilcoxon Mann-Whitney test was used to compare the groups. RESULTS: The mean numbers of nucleoli and AgNORs were higher in lymphocytes and prolymphocytes compared with those from reactive lymph nodes used as controls. Numbers of nucleoli and AgNORs were higher (not significant) in the NS type of Hodgkin's disease than in the MC type. There was a significant increase in numbers of nucleoli in HRS cells, and their AgNOR counts were increased. The greatest number of nucleoli in HRS cells was found in the NS type. Furthermore, the nucleolar activity of HRS cells was greater in the NS type compared with the MC type (50.2 (SEM 3.9) v 37.7 (2.9) AgNORs per nucleus (p = 0.025)). Comparative analysis of cytological and histological samples showed that the AgNOR score was significantly higher in touch imprints than in tissue sections with tumours of the same histological type. CONCLUSIONS: Assessment of cell activity in Hodgkin's disease patients by silver staining is more convenient and informative in lymph node imprints than in histological sections. The highest expression of interphase ribosomal RNA cistrons found in NS HRS cells is probably explained by their high proliferative activity and elevated production of transforming growth factor 1 which is known to be the most potent cytokine present in the NS subtype of Hodgkin's disease.

    The classical cable equation, in which membrane conductance is considered constant, is modified by including the linearized effect of membrane potential on sodium and potassium ionic currents, as formulated in the Hodgkin-Huxley equations for the squid giant axon. The resulting partial differential equation is solved by numerical inversion of the Laplace transform of the voltage response to current and voltage inputs. The voltage response is computed for voltage step, current step, and current pulse inputs, and the effect of temperature on the response to a current step input is also calculated.The validity of the linearized approximation is examined by comparing the linearized response to a current step input with the solution of the nonlinear partial differential cable equation for various subthreshold current step inputs.All the computed responses for the squid giant axon show oscillatory behavior and depart significantly from what is predicted on the basis of the classical cable equation. The linearization procedure, coupled with numerical inversion of the Laplace transform, proves to be a convenient approach which predicts at least qualitatively the subthreshold behavior of the nonlinear system.

    Background Women treated for Hodgkin’s lymphoma (HL) have an elevated risk of developing second breast cancer (SBC) compared with the general population. We planned this meta-analysis to quantify the long-term risk of SBC and analyze the contributing risk factors among HL survivors. Methods According to predefined selection criteria, literature search identified 34 studies that were included in the analyses. Results After eliminating overlapping or duplicate data, 957 incidences of SBC were encountered in 24,505 females with HL over a median follow-up of 14.9?years. The medians: age at the diagnosis of HL, age at diagnosis of SBC, and latency since HL treatment to the development of SBC were 23.7, 35.0, and 17.7?years, respectively. The pooled relative risk (RR) of SBC was 8.23 (95% CI, 5.43-12.47, I2?=?96%), with a median absolute excess rate of 22.9 per 10,000 person-years. The RR was found inversely related to age at diagnosis of HL with the highest rate (68.7; [95%CI, 28.08-168.11], I2?=?79%), occurred in young patients (? 15?years old), where the RR in older women (? 40?years old) was not significant (0.55; [95% CI, 0.09-3.52]). Analysis of RR by 5-year increments since the treatment of HL showed that the risk was highest after 15–19?years of latency (13.87; [95% CI, 7.91-24.30], I2?=?89%). Analysis of the effect of treatment modalities showed that the RR rates were (4.70; [95% CI, 3.28-6.75], I2?=?74%), (5.65; [95%CI, 2.94-10.88], I2?=?91%), and (1.19; [95% CI, 0.50-2.82], I2?=?65%), for radiotherapy (RT) only, combined RT and chemotherapy (CT), and CT only, respectively. To investigate the demonstrated heterogeneity, meta-regression analysis was performed when feasible. In most such analyses, the natural logarithm of RR was inversely associated with age at HL diagnosis. Conclusions We conclude that, the current meta-analysis provided the most recent comprehensive estimate of the risk of SBC in a broad-range of HL survivors. Younger age at diagnosis proved to be a dominant risk factor. The obtained results would serve providing breast cancer screening recommendations for HL survivors. PMID:22639888

  17. The Chinese Calendars

    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.

    Background—In vitro the Epstein-Barr virus (EBV) encoded latent membrane protein 1 (LMP-1) has been shown to upregulate expression of matrix metalloproteinase 9 (MMP-9), a member of a family of zinc dependent endopeptidases that is believed to facilitate tumour invasion and metastasis by degradation of the extracellular matrix. Aim—To test whether the expression of MMP-9 in Hodgkin's disease correlates with EBV status and survival and to investigate whether LMP-1 expression affects MMP-9 concentrations in the Hodgkin's disease cell line, L428. Methods—MMP-9 expression was measured by means of immunohistochemistry in a series of Hodgkin's disease tumours and this expression was correlated with EBV status and survival. The influence of LMP-1 on MMP-9 expression was also investigated in the Hodgkin's disease cell line, L428. Results—MMP-9 expression was demonstrated in the malignant Hodgkin and Reed-Sternberg cells of all (n = 86) formalin fixed, paraffin wax embedded Hodgkin's disease tumours examined. Although the intensity of MMP-9 immunostaining varied between cases, there was no correlation between MMP-9 expression and EBV status or survival. MMP-9 expression was also detected in a variety of non-malignant cells, including fibroblasts. MMP-9 was detected by zymography in the L428 and KMH2 Hodgkin's disease cell lines, whereas low or undetectable amounts of MMP-9 were found in the L591 Hodgkin's disease cell line. Induction of LMP-1 expression in the Hodgkin's disease cell line L428 did not result in a detectable increase in the values of MMP-9 as measured by zymography. Conclusions—These results demonstrate that MMP-9 is consistently expressed by the Hodgkin and Reed-Sternberg cells of Hodgkin's disease tumours and by the Hodgkin's disease cell lines, L428 and KMH2. However, this expression does not appear to be related either to LMP-1 values or to survival. PMID:10897334

    Sideroblastic anemia after treatment for Hodgkin's disease was seen in two patients 3 years after completion of radiation therapy and chemotherapy. This was followed in both by the development of myelomonoblastic leukemia. No evidence of recurrent Hodgkin's disease was present in either patient. Our observation suggests that development of sideroblastic anemia in patients previously treated for Hodgkin's disease is probably secondary to the treatment and is a preleukemic event.

    The incidence of Hodgkin lymphoma has increased among adolescents and young adults in recent decades, but the relevant risk factors in early life are still unknown. A national cohort study was conducted of 3,571,574 individuals born in Sweden in 1973–2008 and followed up for Hodgkin lymphoma incidence through 2009, to examine perinatal and family risk factors for Hodgkin lymphoma in childhood through young adulthood (ages 0–37 years). There were 943 Hodgkin lymphoma cases identified in 66.3 million person-years of follow-up. High fetal growth was associated with an increased risk of Hodgkin lymphoma after adjustment for gestational age at birth and other potential confounders (Ptrend = 0.005). Family history of Hodgkin lymphoma in a sibling or parent also was strongly associated with an increased risk, with adjusted hazard ratios = 8.83 (95% confidence interval: 3.67, 21.30) and 7.19 (95% confidence interval: 3.58, 14.44), respectively. No association was found between gestational age at birth, birth order, twinning, parental age, or parental education and Hodgkin lymphoma. These findings did not vary by age at Hodgkin lymphoma diagnosis. Similar associations were found for nodular sclerosis and mixed cellularity subtypes. These findings suggest that perinatal factors including possible growth factor pathways may contribute to the risk of Hodgkin lymphoma in childhood through young adulthood. PMID:23171883

    Hodgkin's disease, the syndrome of enlarged lymph nodes associated with enlarged spleen, was described in 1832 on the basis of the gross appearance of the affected parts. The eponym entered the medical literature after repeated attempts by Dr. Samuel Wilks to credit Thomas Hodgkin with the priority of discovery. Today, this malady, also known by many other names, is recognized by microscopic examination of histological features. Hodgkin also described retroversion of the aortic valves with insufficiency in 1827 but Dr. Dominic Corrigan, whose report appeared in 1832, was credited with the eponym, despite efforts again by Wilks on behalf of Hodgkin.

    Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) has clinicopathologic, immunophenotypic, and molecular features that are distinct from classical Hodgkin lymphoma (cHL). Distinguishing these entities is usually straightforward, but unusual variants of NLPHL have been described that can be problematic diagnostically and potentially have clinical significance. We describe a case of NLPHL showing a variant histologic pattern characterized by small and large clusters of lymphocyte predominance cells within nodules defined by follicular dendritic cell meshworks, associated with numerous neutrophils and areas of internodular fibrosis. Focally, the neoplastic cells had lacunar cell-like cytologic features. The resulting combination, not previously reported, closely mimicked the syncytial variant of nodular sclerosis cHL. After chemotherapy the patient was free of disease 14 years later. In our review of the literature we identified rare cases of NLPHL that had similar histologic features, but lacked the neutrophilic infiltration. Recognition of this rare variant, facilitated by immunohistochemical studies in this case, further expands the morphologic spectrum of NLPHL. PMID:19730363

  6. Tree Biomass Estimation of Chinese fir (Cunninghamia lanceolata) Based on Bayesian Method

    Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) is the most important conifer species for timber production with huge distribution area in southern China. Accurate estimation of biomass is required for accounting and monitoring Chinese forest carbon stocking. In the study, allometric equation was used to analyze tree biomass of Chinese fir. The common methods for estimating allometric model have taken the classical approach based on the frequency interpretation of probability. However, many different biotic and abiotic factors introduce variability in Chinese fir biomass model, suggesting that parameters of biomass model are better represented by probability distributions rather than fixed values as classical method. To deal with the problem, Bayesian method was used for estimating Chinese fir biomass model. In the Bayesian framework, two priors were introduced: non-informative priors and informative priors. For informative priors, 32 biomass equations of Chinese fir were collected from published literature in the paper. The parameter distributions from published literature were regarded as prior distributions in Bayesian model for estimating Chinese fir biomass. Therefore, the Bayesian method with informative priors was better than non-informative priors and classical method, which provides a reasonable method for estimating Chinese fir biomass.

    An analysis of complications of therapy requires long-term and frequent followup. Reported here is a review of 179 consecutive children with Hodgkin's disease from Stanford University Medical Center who were seen, treated, and followed over a 20-year period. Complications of treatment are related to the extent of disease and the aggressiveness of therapy. Severe complications from radiotherapy are associated with high-dose, extended-field treatment in preadolescent children. Severe chemotherapy-associated complications include immunosuppression, sterility, and secondary oncogenesis. As cure rates are increasingly optimistic among children with Hodgkin's disease, successful treatment with minimal morbidity remains our greatest challenge. Therapy programs require continual refinement utilizing assessment of short- and long-term side effects of treatment.

    Mantle irradiation is often part of the treatment for Hodgkin's disease. Localized pneumonitis and fibrosis are well-known sequelae of this treatment. We report nine patients with unusual thoracic radiographic findings following treatment for Hodgkin's disease. All nine had mediastinal widening. Seven of these patients received combined modality therapy in which prednisone was given with their MOPP. In these seven patients, an increase in mediastinal width developed at the same time as the radiographic changes of radiation pneumonitis. Two patients developed bilateral infiltrates extending beyond the field of radiation to the lung periphery. In one of these patients, a spontaneous pneumomediastinum developed. One patient underwent mediastinal biopsy that revealed inflammatory changes similar to those seen in radiation pneumonitis. All patients either responded to steroids or had spontaneous regression of radiographic abnormalities supporting the presumed diagnosis of treatment related changes. Recognition of these unusual sequelae of mantle irradiation will aid in differentiating them from infection or tumor and lead to prompt, appropriate treatment.

    Hodgkin's lymphoma has been traditionally defined as a hematopoietic neoplasm composed of diagnostic Reed-Sternberg cells. More than 70% of the cases involve cervical or supraclavicular lymph nodes. Isolated sub-diaphragmatic lymphadenopathy or organ involvement is rare. We present the case of Hodgkin's lymphoma in a 51 years old female, who presented with obstructive jaundice and lymphadenopathy, empirically treated previously as a case of tuberculosis. Chemotherapy with modified ABVD protocol was given with dose modification according to LFT's. Her liver functions returned to normal levels after the first cycle. The main purpose of reporting the case is to stress definitive diagnosis of the disease before initiating treatment and the modified chemotherapy regimen used in this infrequent presentation of the disease.

    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

    The question of thyroid neoplasia following high-dose radiation treatment to the neck and mediastinum for malignant neoplasms such as Hodgkin's lymphoma in children and young adults has been raised recently. Five patients, 19 to 39 years old, were operated on for thyroid neoplasms that developed following cervical and mediastinal radiation therapy for Hodgkin's lymphoma. Three patients had papillary carcinomas and two had follicular adenomas. The latency period between radiation exposure and the diagnosis of thyroid neoplasm ranged from eight to 16 years. This limited series provided strong support for the recommendation that children and young adults who are to receive high-dose radiation therapy to the head, neck, and mediastinum should receive suppressive doses of thyroxine prior to radiation therapy in order to suppress thyrotropin (thyroid-stimulating hormone) and then be maintained on a regimen of suppression permanently.

    The number of patients achieving long-term survival following neck irradiation for Hodgkin's disease and other malignancies is increasing. Paralleling this increase in survivors is the development of late complications of the therapy itself. Eleven patients have previously been reported who developed Graves ophthalmopathy 18 months to seven years after receiving neck radiotherapy for nonthyroidal malignancies. The seven patients who had HLA typing were all HLA-B8 negative, despite the reported association of the HLA-B8 antigen with Graves disease. A patient who is HLA-B8 positive who developed Graves ophthalmopathy and hyperthyroidism nine years after receiving mantle radiotherapy for Hodgkin's disease is reported. It is recommended that Graves disease be included among the thyroid diseases that receive consideration during follow-up of patients who have received mantle radiotherapy.

    Retinoblastoma (Rb) tumour-suppressor protein plays a critical role in cell cycle control. Rb inactivation is a frequent phenomenon in tumours of different cell lineages, in which the absence of Rb protein has been considered to be a marker of Rb disregulation. We used modern immunohistochemical techniques to study the expression of Rb protein in a large series of 130 patients with Hodgkin's disease. Simultaneously, Western blot was used to analyse a more restricted group (12 patients) to confirm the immunohistochemical results and to clarify the phosphorylation status of Rb protein. As the level of Rb expression varied according to cell cycle stage, we also performed immunostaining for Ki67, a protein present in proliferating cells. To make comparison possible, we first characterised the amount and phosphorylation status of Rb protein in reactive lymphoid tissue and phytohaemagglutinin (PHA)-stimulated lymphocytes. The presence of p53 in Sternberg-Reed cells was also included in the study, as both proteins (p53 and Rb) have been found to be closely associated in cell cycle control. PHA-stimulated peripheral blood lymphocytes showed a parallel increase in Rb and cell cycle progression, together with progressive Rb phosphorylation. In reactive lymphoid tissue there was also a clear correlation between Rb expression and the Ki67 proliferation index (R = 0.96, P = 0.038). When analysing Hodgkin's disease samples, a clear difference emerges between cases of nodular lymphocyte predominance, which preserve the relationship between Rb and Ki67 expression (r = 0.8727, P = 0.000), and classical forms of Hodgkin's disease (nodular sclerosis and mixed cellularity), which display a strong deviation from this pattern. Two main anomalies were found: (1) One group of 21/130 cases with partial or total loss of Rb protein expression, which could reflect the existence of genetic alterations, or an altered transcriptional or translational regulation of Rb gene. (2) Another group with an abnormally high Rb/Ki67 ratio, which could support conflicting interpretations: (i) excess Rb protein for controlling cell cycle progression; or (ii) adhesion of Rb protein to other cellular or viral proteins, such as p53 and MDM2. The results of this study indicate an anomalous pattern of expression of Rb in classical forms of Hodgkin's disease, and suggest the possibility of undertaking functional studies (E1A adhesion, p16 expression) with the aim of better characterising the status of Rb protein, and correlating these findings with clinical course in Hodgkin's disease patients.

    AIMS--To assess the effect of microwave heating on immunohistochemical staining of CD15 and CD30 antigens in Hodgkin's disease tissue samples. METHODS--Formalin fixed, paraffin wax embedded sections from 20 cases of Hodgkin's disease (six mixed cellularity, 14 nodular sclerosis) were immunostained for CD15, using two antibodies (DAKO-M1 and Leu-M1) and for CD30 using the antibody Ber-H2. The staining was carried out by conventional techniques which included pretreatment of sections with trypsin and on untreated sections following heating with microwaves. With antibody Leu-M1 an additional method, using a specific antimouse IgM bridge both with and without microwave heating, was also included. The results for each method were compared by counting positively stained Reed-Sternberg cells and estimating the staining intensity. RESULTS--Microwave heating resulted in a substantial increase in the number of cells stained with antibodies to CD15 and also in the staining intensity. The best results were obtained using Leu-M1 with specific rabbit anti-mouse IgM bridge and microwave heating. Dramatic enhancement of the staining of Reed-Sternberg cells for CD30 was achieved following microwave heating, together with disappearance of the non-specific staining of plasma cells. CONCLUSION--Microwave heating is strongly recommended for the immunohistochemical staining of CD15 and CD30 expressed by Reed-Sternberg cells in Hodgkin's disease. Images PMID:7904271

    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.

  16. 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.

    Richter’s transformation (RT) represents the development of high grade lymphoma, most commonly diffuse large B-cell lymphoma, in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL). CLL/SLL may convert also to Hodgkin’s lymphoma, the so-called Hodgkin’s variant of Richter transformation. Histopathological proof is needed to confirm a definitive diagnosis. Patients with RT generally have a poor prognosis, with prompt recognition optimise clinical management. Whole-body PET scan with 18F-FDG can be used for detection of RT of CLL/SLL. We describe the case of 64-year-old woman with CLL/SLL who developed Hodgkin lymphoma detected with PET/CT. PMID:24963449

    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.

    Background Dioxin emissions from municipal solid waste incinerators are one of the major sources of dioxins and therefore are an exposure source of public concern. There is growing epidemiologic evidence of an increased risk for non-Hodgkin's lymphoma (NHL) in the vicinity of some municipal solid waste incinerators with high dioxin emission levels. The purpose of this study was to examine this association on a larger population scale. Methods The study area consisted of four French administrative departments, comprising a total of 2270 block groups. NHL cases that had been diagnosed during the period 1990–1999, and were aged 15 years and over, were considered. Each case was assigned a block group by residential address geocoding. Atmospheric Dispersion Model System software was used to estimate immissions in the surroundings of 13 incinerators which operated in the study area. Then, cumulative ground-level dioxin concentrations were calculated for each block group. Poisson multiple regression models, incorporating penalized regression splines to control for covariates and dealing with Poisson overdispersion, were used. Five confounding factors were considered: population density, urbanisation, socio-economic level, airborne traffic pollution, and industrial pollution. Results A total of 3974 NHL incident cases was observed (2147 among males, and 1827 among females) during the 1990–1999 time period. A statistically significant relationship was found at the block group level between risk for NHL and dioxin exposure, with a relative risk (RR) of 1.120 (95% confidence interval [CI] 1.002 – 1.251) for persons living in highly exposed census blocks compared to those living in slightly exposed block groups. Population density appeared positively linked both to risk for NHL and dioxin exposure. Subgroup multivariate analyses per gender yielded a significant RR for females only (RR = 1.178, 95% CI 1.013 – 1.369). Conclusion This study, in line with previous results obtained in the vicinity of the incinerator located in Besançon (France), adds further evidence to the link between NHL incidence and exposure to dioxins emitted by municipal solid waste incinerators. However, the findings of this study cannot be extrapolated to current incinerators, which emit lower amounts of pollutants. PMID:18959776

    Introduction Hodgkin’s disease is highly curable by radiotherapy and/or chemotherapy, but refractory disease or early relapses are rarely cured by conventional salvage therapy. Case presentation We report a case of a 20-year-old Caucasian man, with a biopsy-proven intrapulmonary relapse of Hodgkin’s disease, for whom salvage chemotherapy was administered. During salvage chemotherapy intense increased F18-fluorodeoxyglucose uptake was noticed in multiple lymph nodes and diffuse increased splenic uptake, suggesting chemotherapy-refractory disease. However, additional information obtained from the patient revealed he recently had met his first girlfriend. An asymptomatic primary Epstein–Barr virus infection was considered proven. Conclusions Interim F18-fluorodeoxyglucose-positron emission tomography/computed tomography is a strong prognostic factor for advanced Hodgkin’s and may better identify those patients needing intensified chemotherapy. Related to the nonspecificity of F18-fluorodeoxyglucose, clinical awareness of the potential interference of intercurrent asymptomatic viral infections with treatment and remission status monitoring continues to be important in the interpretation of equivocal medical imaging results.

    Intrahepatic cholestasis in the form of paraneoplastic phenomena is an uncommon presentation of Hodgkin's lymphoma (HL). Herein we report the diagnosis of mixed type HL-related idiopathic intrahepatic cholestasis in a 73-year-old man presenting with jaundice, after the inguinal lymph node biopsy indicative of mixed cellular type HL and liver biopsy consistent with intrahepatic cholestasis, following several diagnostic interventions including surgery for suspected extrahepatic obstructive cholestasis. Our findings emphasize the value of early liver biopsy in the diagnostic algorithm along with consideration of HL-related idiopathic intrahepatic cholestasis as a diagnosis of exclusion in cholestatic jaundice of obscure origin.

    A FT-IR microspectroscopy study on reactive lymph nodes and non-Hodgkin lymphomas is reported. Mid infrared absorption spectra collected at diffraction limit spatial resolution from reactive and neoplastic lymph nodes resulted sufficiently different once analysed by multivariate pattern recognition analysis to distinguish tumoral from non tumoral samples. The potential of infrared spectroscopy as a post-operative screening is gained by the use of a multielement Focal Plane Array detector. Spectral differences between normal and malignant spectra were mainly in the methyl stretching and in the low frequency region.

Their development of gnomon & ruler, sundial, and water clock apparatuses enabled Chinese astronomers to measure the annual solar orbit and solar day more precisely than their contemporaries. I have built one of each of these devices to use in collecting data from Olympia, Washington. I will measure the solar day in the Pacific Northwest following the methodology of the ancient Chinese. I will compare with my data, the available historical Chinese astronomical records and current records from the United States Naval Observatory Master Clock. I seek to understand how ancient Chinese investigations into solar patterns enabled them to make accurate predictions about the movement of the celestial sphere and planets, and to develop analytic tests of their theories.

  11. On Classical Teleportation and Classical Nonlocality

    An interesting protocol for classical teleportation of an unknown classical state was recently suggested by Cohen, and by Gour and Meyer. In that protocol, Bob can sample from a probability distribution P that is given to Alice, even if Alice has absolutely no knowledge about P. Pursuing a similar line of thought, we suggest here a limited form of nonlocality - "classical nonlocality". Our nonlocality is the (somewhat limited) classical analogue of the Hughston-Jozsa-Wootters (HJW) quantum nonlocality. The HJW nonlocality tells us how, for a given density matrix rho, Alice can generate any rho-ensemble on the North Star. This is done using surprisingly few resources - one shared entangled state (prepared in advance), one generalized quantum measurement, and no communication. Similarly, our classical nonlocality presents how, for a given probability distribution P, Alice can generate any P-ensemble on the North Star, using only one correlated state (prepared in advance), one (generalized) classical measurement, and no communication. It is important to clarify that while the classical teleportation and the classical non-locality protocols are probably rather insignificant from a classical information processing point of view, they significantly contribute to our understanding of what exactly is quantum in their well established and highly famous quantum analogues.

    An imbalance in folate metabolism can adversely affect DNA synthesis and methylation systems which can lead to susceptibility to non-Hodgkin lymphoma (NHL). Whether single nucleotide polymorphisms (SNPs) and their haplotypes in the methylenetetrahydrofolate reductase (MTHFR) are associated with NHL, remain inconclusive. We investigated the association between MTHFR C677T and A1298C SNPs and NHL risk in a population which is made up of Malay, Chinese and Indian ethnic subgroups. A total of 372 NHL patients and 722 controls were genotyped using the Sequenom MassARRAY platform. Our results of the pooled subjects failed to demonstrate significant association between the MTHFR C677T and A1298C SNPs with NHL and its subtypes. The results were in agreement with the previous meta-analyses. In the Indian ethnic subgroup however, single locus analysis of MTHFR A1298C appears to confer risk to NHL (Odds ratio (OR) 1.91, 95% confidence interval (95% CI) 1.22-3.00, P=0.006). The risk is almost doubled in homozygous carrier of MTHFR 1298CC (OR 4.03, 95% CI 1.56-10.43, P=0.004). Haplotype analysis revealed higher frequency of CC in the Indian NHL patients compared with controls (OR 1.86, 95% CI 1.18-2.93, P=0.007). There is lack of evidence to suggest an association between MTHFR C677T and A1298C with the risk of NHL in the Malays and Chinese. In the Indians however, the MTHFR A1298C confers risk to NHL. This study suggests ethnicity modifies the relationship between polymorphisms in the folate-metabolizing gene and NHL. PMID:24646728

  19. A Multi-Component Model of Hodgkin's Lymphoma.

    PubMed

    Staege, Martin S

    2015-01-01

    Hodgkin's lymphoma is an example for a tumor with an extremely tight interaction of tumor cells with cells from the tumor micro-environment. These so-called bystander cells are not inert but interact actively with the tumor cells. Some of these cells support tumor growth by delivery of co-stimulating and anti-apoptotic signals ("helper cells"). Other cells ("killer cells") are involved in the anti-tumor immune response which is obviously not efficient enough for tumor elimination. The activity of both helper cells and killer cells is regulated by additional cells in the stroma ("regulatory cells"). The dynamic behavior of such multi-component systems is difficult to predict. In the present paper we propose a model that can be used for simulation of essential features of this system. In this model, tumor growth depends on (i) presence of few cancer stem cells, (ii) co-stimulation of cancer cells by the tumor stroma, (iii) activity of regulatory cells that suppress killer cells without suppression of helper cells. The success of cytotoxic/cytostatic therapy in this model varies depending on the therapy-related toxicity for each of the cell populations. The model also allows the analysis of immunotherapeutic interventions. Under certain conditions, paradox enhancement of tumor growth can occur after therapeutic intervention. The model might be useful for the design of new treatment strategies for Hodgkin's lymphoma and other tumors with prominent tumor-stroma interaction. PMID:25915037

    Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) often present with systemic symptoms such as fatigue, shortness of breath and night sweats, mimicking pregnancy-related features which may result in delayed disease diagnosis. Furthermore, the wish to avoid investigational imaging, aiming to protect the fetus from radiation exposure, may lead to a further delay, which does not often result in significant changes in HL clinical nature and patient outcome. In contrast, a more aggressive behavior (i.e., advanced disease stage and reproductive organ involvement) of most NHL types diagnosed in pregnancy may require urgent therapeutic intervention to prevent disease progression. Current management of pregnancy-associated NHL depends on histological subtype of the disease, gestational stage at diagnosis and the urgency of treatment for a specific patient. Patients diagnosed with indolent lymphoma may often be just followed, whereas those presenting with aggressive or highly aggressive disease need to be urgently treated with chemoimmunotherapy, either after undergoing an elective pregnancy termination if diagnosed at an early gestational stage, or with pregnancy preservation, if diagnosed later. Supportive care of NHL is also important; however, granulocyte colony stimulating factor (G-CSF) which is commonly used outside of pregnancy, should be cautiously employed, considering its established teratogenicity in animals, though this is less proven in humans. In conclusion, given the paucity of studies prospectively evaluating the outcome of pregnant women with NHL, international efforts are warranted to elucidate critical issues and develop guidelines for the management of such patients.

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.

    Primary gastrointestinal lymphoma is the most common extranodal presentation of non-Hodgkin's lymphoma. In this retrospective study, all cases of primary gastrointestinal lymphoma registered at Kuwait Cancer Control Center between January 1992 and December 2001 were reviewed. Patients were diagnosed through an endoscopic biopsy or exploratory laparotomy. Staging procedures included computed axial tomography scan, bone marrow biopsy, barium and follow-through study, as well as routine chemistry (including lactate dehydrogenase) and hemography. There were 46 patients (30 men and 16 women); ages ranged from 16 to 82 years (median age, 43.6 years). The most common site of involvement was the stomach (70%), and the most common histology was large B cell. At least 50% of cases underwent primary radical surgery, and the majority of patients received subsequent chemotherapy and/or local radiation therapy. Chemotherapy consisted of the CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) regimen for large B-cell histology and CVP (cyclophosphamide/vincristine/prednisone) or oral alkylating agents for low-grade histology. Of this cohort, only 12 cases (26%) have had local or distant relapse. Disease-free survival rates for low-grade and high-grade non-Hodgkin's lymphoma were 64% and 81%, respectively. Primary gastrointestinal lymphoma is a potentially curable malignancy. PMID:14556681

    Hodgkin lymphomas are malignant hemato-lymphoid neoplasms involving lymph nodes and extra-nodal sites. Bone marrow infiltration at diagnosis is uncommon, occurring in approximately 10 % cases. Such infiltration, when present, is usually focal and often associated with extensive disease, systemic symptoms, cytopenias and unfavorable histology. In the unusual event of the absence of significant peripheral lymphadenopathy, these lymphoma-related B-symptoms may easily masquerade as an infectious illness. A 30-year-old male was initially administered inappropriate anti-tubercular chemotherapy in a primary care setting for a presumptive impression of pulmonary tuberculosis. On re-evaluation due to unresponsiveness to the drugs, bulky mediastinal lymphadenopathy was detected. However, his axillary lymph node aspirate revealed epithelioid cell granulomas further confounding the picture. The correct diagnosis of Hodgkin lymphoma was finally established when a bone marrow biopsy (for fever and pancytopenia) revealed the typical neoplastic Reed Sternberg cells that were confirmed immunohistochemically. The case highlights the necessity of an early bone marrow examination in patients with unexplained fever and peripheral blood cytopenias. Physicians in tropical third-world countries with resource constraints and high disease burdens need to strike a fine balance between maintaining a high index of suspicion for tuberculosis yet being wary of the risk of missing lymphoma in such patients.

    Purpose: Standards for the reporting of radiotherapy details in randomized controlled trials (RCTs) are lacking. Although radiotherapy (RT) is an important component of curative therapy for Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL), we postulated that RT reporting may be inadequate in Phase III HL and NHL trials. Methods and Materials: We searched PubMed and the Cochrane registry for reports of RCTs involving RT and either HL or NHL published between 1998 and 2007. We screened 133 titles and abstracts to identify relevant studies. We included a total of 61 reports. We assessed these reports for the presence of six quality measures: target volume, radiation dose, fractionation, radiation prescription, quality assurance (QA) process use, and adherence to QA (i.e., reporting of major or minor deviations). Results: Of 61 reports, 23 (38%) described the target volume. Of the 42 reports involving involved-field RT alone, only 8 (19%) adequately described the target volume. The radiation dose and fractionation was described in most reports (54 reports [89%] and 39 reports [64%], respectively). Thirteen reports specified the RT prescription point (21%). Only 12 reports (20%) described using a RT QA process, and 7 reports (11%) described adherence to the QA process. Conclusion: Reporting of RT in HL and NHL RCTs is deficient. Because the interpretation, replication, and application of RCT results depend on adequate description and QA of therapeutic interventions, consensus standards for RT reporting should be developed and integrated into the peer-review process.

  7. Aspiration in Chinese

    NASA Astrophysics Data System (ADS)

    Chao, Huey-Ju.

    This dissertation studies aspiration in Chinese in these four areas: the temporal relationships between aspiration and the vowel of the syllable, the perception of aspiration, the correlation between pitch and aspiration, and the role of aspiration in a historical change in Chinese. Data based on 144 words with aspiration contrasts were derived from the experiments which involved production and perception by a total of 28 Chinese speakers. On the basis of the measurements of acoustical characteristics of the voice onset time and the lengths of the syllable, a constant ratio model has been proposed to describe the timing relationships among the elements within a syllable. The perceptual experiment tested the cues of aspiration by deleting the portion of the voice onset time from the syllable on the front, back, middle and both ends. The results are reported and discussed. The effects of aspiration on intrinsic tone heights in Mandarin were measured and the significance calculated. Finally some attempts are made to solve the development of aspiration from voiced obstruents under the condition of different tones from Middle Chinese to modern dialects.

    Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) and classical Hodgkin lymphoma (CHL) are classified separately because of their distinct clinical and pathological features. While EBV is detected in the neoplastic cells of 25-70% of CHL, NLPHL is generally considered to be EBV-negative. We assessed EBV status in 302 pediatric and adult cases of NLPHL. A total of 145 pediatric (age ?18) and 157 adult cases of NLPHL were retrieved from 3 North American centers and tested for EBV by in situ hybridization (EBER). Clinical and pathological features were analyzed. Five (3.4%) pediatric and 7 (4.5%) adult NLPHL cases contained EBV-positive LP cells. While all 12 cases met criteria for the diagnosis of NLPHL, atypical features were present, including capsular fibrosis, atrophic germinal centers and pleomorphic or atypical lymphocyte predominant (LP) cells. Both CD20 and OCT-2 expression were strong and diffuse in all except one case. However, PAX5 and CD79a were weak and/or variable in 7/8 and 6/6 cases tested, respectively. EBV-positive cases were more likely to be CD30-positive (75%) than EBV-negative cases (25%) (p=0.0007); CD15 was negative in all cases. Our results show that EBV-positive LP cells may occur in NLPHL. Distinguishing EBV+ NLPHL from CHL can be challenging, since EBV+ NLPHL can have partial expression of CD30 and weak PAX5 staining as well as pleomorphic-appearing LP cells. However, the overall appearance and maintenance of B-cell phenotype, with strong and diffuse CD20 and OCT-2 expression, support the diagnosis of NLPHL in these cases. PMID:24525501

    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.

    Aggressive non Hodgkin lymphoma (NHL) occurs frequently in the elderly and because of drug related toxicity treatment remains controversial. Seventy-two patients over 65 years (68-83 y, median 73 y) with intermediate and high grade NHL were retrospectively studied. We found 22 cases of high grade NHL and diffuse large cell the most frequent type encountered (54%). Seven patients had stage I, 8 stage II, 14 stage III, and 43 stage IV disease. Treatment for localized disease was radiotherapy or chlorambucil, and disseminated stage patients were treated by three different chemotherapy regimens, group I: classic dose chemotherapy without Adriamycin (15 pts), group II: same type of regimen with Adriamycin (45 mg/m2) (42 pts), group III: high dose chemotherapy with Adriamycin (75 mg/m2) (8 pts). Overall complete response (CR) rate was 53% without significant differences between treatment groups. Median duration of survival was 38 months and estimated 5 year survival at 40%. Following complete remission, 15 patients (40%) relapsed. Thirty-seven patients have died, 6 from toxic deaths (5 toxic deaths in group II and III), 28 from NHL, and 3 from other diseases. Toxicity was greater among patients treated with Adriamycin. In a multivariate analysis, the attainment of complete remission was the only factor influencing survival. Our data shows that classical dose chemotherapy leads to the same CR rate and survival as more intensive regimens. PMID:2377447

    Tsukamurella spp. infection is a rare but important cause of bacteremia in immunocompromised patients. The organism is an aerobic, Gram-positive, weakly acid-fast bacillus that is difficult to differentiate from other aerobic Actinomycetales by standard laboratory methods. Here, we report on the case of a 14-year-old patient with Hodgkin's lymphoma who, after intensive chemotherapy, developed Tsukamurella inchonensis bacteremia, which was identified on the peripherally inserted central venous catheter (PICC) using 16S rRNA sequencing analysis. The bacteremia was successfully controlled with antimicrobial therapy and subsequent removal of the PICC. This is the first report of bacteremia by Tsukamurella inchonensis in immunocompromised children. Careful observation and prompt analysis of opportunistic infection, including Tsukamurella spp., is very important in immunocompromised children. PMID:25711272

    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...

    Non-Hodgkin's lymphomas (NHL) are a heterogeneous group of lymphoproliferative disorders originating in B lymphocytes, T lymphocytes, or natural killer cells. Mantle cell lymphoma (MCL) accounts for approximately 6% of all newly diagnosed NHL cases. Radiation therapy with or without systemic therapy is a reasonable approach for the few patients who present with early-stage disease. Rituximab-based chemoimmunotherapy followed by high-dose therapy and autologous stem cell rescue (HDT/ASCR) is recommended for patients presenting with advanced-stage disease. Induction therapy followed by rituximab maintenance may provide extended disease control for those who are not candidates for HDT/ASCR. Ibrutinib, a Bruton tyrosine kinase inhibitor, was recently approved for the treatment of relapsed or refractory disease. This manuscript discusses the recommendations outlined in the NCCN Guidelines for NHL regarding the diagnosis and management of patients with MCL. PMID:25190696

    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

    Idelalisib is a novel, highly selective, small-molecule, tyrosine kinase inhibitor with potent activity against phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit delta isoform (PI3K?). Given the highly selective inhibition of this compound, studies have shown that idelalisib is able to achieve significantly increased apoptotic activity in B-cell acute lymphoblastic leukemia (B-ALL) and chronic lymphocytic leukemia (CLL) cell lines, without significant increase in apoptosis among normal T and natural killer cells. Recent studies have suggested potential clinical benefit with idelalisib as either a single agent or in combination with established chemotherapeutic compounds including bendamustine and rituximab in relapsed/refractory CLL. This review will focus on the preclinical pharmacology, pharmacokinetics and clinical utility of idelalisib in the treatment of various indolent forms of non-Hodgkin's lymphoma. PMID:24619588

    Non-Hodgkin lymphomas(NHL) encompass various types of lymphoid neoplasms with different biological behavior. Comprehensive genomic analysis identifies novel mutation and signaling pathways in various tumors, which leads to rational approaches in cancer therapy. Molecular target therapy is a new approach focusing on specific protein or signaling pathways. Molecules of signaling pathways of B-cell receptor, PI3K/Akt/mTOR and NF-kappaB are rational target, and many new drugs targeting the pathways are developing in various subtypes of lymphoma. Monoclonal and novel conjugated antibodies for cell surface proteins, epigenetic modulators and immunomodulatory agents also show promising clinical activities. This review will focus on the new molecular target drugs and their activity in NHL. PMID:25016812

    Non-Hodgkin’s lymphoma (NHL) is among the haematological malignancies with high prevalence worldwide, causing estimated 355?900 new cases and 191?400 deaths in 2008. High prevalence of NHL is documented in economically more developed areas while low prevalence is observed in less developed areas of the globe. A wide array of environmental factors have been reported to be either directly involved or in modifying the risk of NHL development. In addition to these factors, a number of infectious agents, chiefly viruses have also been implicated in the development of NHL. This article reviews the available literature to discuss the role of hepatitis viruses in NHL development, possible mechanisms of lymphomagenesis and also identify the areas in which further research is required to better understand this disease. A brief discussion on the clinical aspects such as classification, staging, treatment approaches have also been included in this article. PMID:24175222

    Langerhans cell histiocytosis (LCH) is a rare neoplasm defined as the proliferation of bone marrow langerhans cells, which is a kind of dendritic cells. The major pathological features of LCH are expression of CD1a and S100 as well as Birbeck granules. Its presentation can differ from a mild bone lesion to a multi-systemic evolved malignant neoplasm; however, the latter outcome is almost rare. Thus, LCH is mostly known as a benign neoplasm. In this study, we present a case of LCH followed by Hodgkin lymphoma (HL). Accompaniment of this disease with malignant lymphoma is rare and considered as case report. Several cases in which malignant lymphoma occurred prior to LCH are reported; however, few cases can be found with LCH followed by malignant lymphomas. PMID:25999631

In ambulatory event telemetry, she reported nocturnal chest pain with transient ST elevation characteristic for acute cardiac ischemia. Urgent coronary angiography with intravascular ultrasound and virtual histology visualization revealed 70% fibrotic stenosis in the proximal segment of the left anterior descending artery successfully treated with a drug-eluting stent implantation. This case is especially noteworthy because of the short period from initial therapy to the symptomatic coronary artery disease that is entirely unlike the reported mean latency period of several years.

    The activity of radio-immuno conjugate in Non-Hodgkin Lymphoma (NHL) has resulted in FDA approval of two antibodies, Y90 Ibritumomab tiuxetan and I131 tositumomab. Both these agents target CD20, a receptor widely expressed in B-Cell NHL. These immunoconjugates deliver their radioactive payload to the malignant clone in the bone marrow and lymph node. Their use has been associated with modest improvement in survival end points among several lymphoma histologies. The promising effect on disease control as well as their efficacy in disease relapse is encouraging in low grade lymphoma. Radioimmunotherapy (RIT) is increasingly being explored in the setting of consolidation as well as conditioning regimens prior to stem cell transplantation. Here, we summarize the clinical use, complications and future applications of RIT in NHL. PMID:22762027

    This immunohistochemical study was carried out to evaluate the role of vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 and -9 (MMP-2 and MMP-9), their inhibitor (tissue inhibitor of metalloproteinase-1, TIMP-1), and microvessel density (MVD) in the clinicopathologic behavior of childhood Hodgkin's lymphoma (HL). Paraffin-embedded histologic sections from 15 children with HL were immunohistochemically stained with MMP-2, MMP-9, TIMP-1, VEGF, and CD31 antibodies to investigate the correlation between the expression of these markers and the clinicopathologic characteristics of HL. Expression of MMP-2 and VEGF in Hodgkin and Reed-Sternberg cells (HRS) was more frequent in nodular sclerosis than in other subtypes (p=0.07 and 0.08, respectively). None of the study parameters in HRS cell were associated with age, sex, disease stage, extranodal disease, and the occurrence of bulky tumor. There was a trend toward advanced stage in negative TIMP-1 staining in HRS cells (p=0.06). In reactive lymphocytes, MMP-2 expression was correlated with MVD (r=0.68, p=0.005), and MMP-9 expression was correlated with B symptoms (p=0.003). Also, low TIMP-1 expression in reactive lymphocytes was frequently found in patients with advanced stage (p=0.048). There was a positive correlation with the ratio of MMP-2 expression in reactive lymphocytes and MVD (r=0.68, p=0.005). Expression of MMP-9 in reactive lymphocytes was correlated with MVD without statistical significance (r=0.487, p=0.06). Our results suggest that, as in many solid tumors, angiogenesis and angiogenic factors may play an important role in childhood HL. Larger series of patients are needed to determine the prognostic value of angiogenesis in childhood HL. PMID:18207652

    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 aim of the present meta-analysis was to examine comprehensively the association between smoking and lymphoma [Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL)] in adults. Eligible studies were identified, and pooled-effect estimates (odds ratios and relative risks) were calculated for ever, current and former smoking, separately by lymphoma subtype and gender. Metaregression analysis with percentage of male patients, mean age, duration (years of smoking), intensity (pack-years and cigarettes per day) and years since quitting was carried out. Out of the 50 eligible articles, 41 used a case-control design (20 143 NHL cases, 4340 HL cases and 61 517 controls), whereas nine used a cohort design (5748 incident NHL cases, 334 HL cases, total cohort size comprising 1 530 833 smokers). Ever smoking was associated with increased risk for NHL [pooled-effect estimate=1.05, 95% confidence interval (CI): 1.00-1.09] mainly because of the association with T-NHL (pooled-effect estimate=1.23, 95% CI: 1.09-1.38). Ever smoking was also associated with increased risk for HL (pooled-effect estimate=1.15, 95% CI: 1.02-1.30); sizeable associations were observed regarding both nodular sclerosis and mixed cellularity subtypes. Although male study arms pointed to predominantly increased risk for HL, metaregression did not confirm the male preponderance. Dose-response patterns were particularly evident for HL. Cigarette smoking seems to be associated with increased lymphoma risk, especially HL and T-NHL. Further well-designed studies seem to be needed so as to investigate the risk thoroughly, especially for T-NHL subentities, and the extent to which confounding may interfere with gender-related disparities.

    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

    This paper studies the statistical characteristics of Chinese surnames, first names and full names based on a credible sample. The distribution of Chinese surnames, unlike that in any other countries, shows an exponential pattern in the top part and a power-law pattern in the tail part. The distributions of Chinese first names and full names have the characteristics of a power law with different exponents. Finally, the interrelation of the first name and the surname is demonstrated by using a computer simulation and an exhibition of the name network. Chinese people take the surname into account when they choose a first name for somebody.

    Purpose To examine ovarian reserve following chemotherapy in women with Hodgkin’s disease. Methods The study included nine patients who underwent ovarian tissue cryopreservation (OTCP) prior to chemotherapy consisting of the ABVD regimen (Adriamycin, bleomycin, vinblastine, and dacarbazine) and co-treatment with gonadotropin-releasing hormone agonist (GnRH-a) (Group A), and 13 patients treated by the ABVD protocol only without GnRH-a (Group B). The average age was 25.2?±?2.7 years for the women in Group A and 31.8?±?6.8 years for those in Group B. Results Six months following the end of chemotherapy, the menstrual cycle resumed in all Group A patients and in four Group B patients who had amenorrhea. Eight Group B patients had regular menses during and after chemotherapy. None of the patients suffered from ovarian failure. Two Group A patients conceived in the first year after completing chemotherapy. Conclusions Co-treatment with GnRH-a has little effect on ovarian protection in women with Hodgkin’s disease.

    The aim of this study was to identify regional structural differences in the brains of native speakers of a tonal language (Chinese) compared to nontonal (European) language speakers. Our expectation was that there would be differences in regions implicated in pitch perception and production. We therefore compared structural brain images in three groups of participants: 31 who were native Chinese speakers; 7 who were native English speakers who had learnt Chinese in adulthood; and 21 European multilinguals who did not speak Chinese. The results identified two brain regions in the vicinity of the right anterior temporal lobe and the left insula where speakers of Chinese had significantly greater gray and white matter density compared with those who did not speak Chinese. Importantly, the effects were found in both native Chinese speakers and European subjects who learnt Chinese as a non-native language, illustrating that they were language related and not ethnicity effects. On the basis of prior studies, we suggest that the locations of these gray and white matter changes in speakers of a tonal language are consistent with a role in linking the pitch of words to their meaning.

    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.

  3. Obesity, Diet and Risk of Non-Hodgkin Lymphoma

    PubMed Central

    Skibola, Christine F.

    2010-01-01

    Non-Hodgkin lymphoma (NHL) represents a group of heterogeneous diseases that significantly vary in their causes, molecular profiles, and natural progression. In 2006, there will be ~59,000 newly diagnosed NHL cases in the U.S. and over 300,000 cases worldwide. While new therapeutic regimens are minimizing the number of deaths related to NHL, causes for the majority of lymphomas remain undetermined. Recent studies suggest that dietary factors may contribute to the rising rates of NHL. This review will summarize epidemiological reports that have studied the relationship between obesity, physical activity, diet and risk of NHL. Based on a number of case-control and prospective cohort studies, overweight/obesity likely increases the risk of NHL; whereas, moderate physical activity may reduce risk. Several studies support an inverse association between intakes of vegetables and NHL risk, particularly for the consumption of cruciferous vegetables. This may relate to the induction of apoptosis and growth arrest in pre-neoplastic and neoplastic cells, two important actions of isothiocyanates found in cruciferous vegetables. Studies also suggest that fish intake may be inversely associated with risk of NHL, though findings have not been entirely consistent. This may relate to the high organochlorine content in some fish that could override a protective effect. High consumption of fats, meat and dairy products also may increase lymphoma risk. The accumulated scientific evidence concerning the associations between obesity, diet, and NHL suggests several identified modifiable risk factors that might be recommended to decrease lymphoma risk.

  4. Loss of synchronization in partially coupled Hodgkin-Huxley equations.

    Labouriau, Isabel S; Alves-Pinto, Carla

    2004-05-01

    We study the loss of synchronization of two partially coupled space-clamped Hodgkin-Huxley equations, with symmetric coupling. This models the coupling of two cells through an electrical synapse. For strong enough coupling it is known that all solutions of the equations approach a state where the two cells are perfectly synchronized, having the same behaviour at each moment. We describe the local bifurcations that arise when the coupling strength is reduced, using a mixture of analytical and numerical methods. We find that perfect synchrony is retained for very small positive values of the coupling strength, for almost all initial conditions. Although perfect synchrony is lost for negative values of the coupling constant, the system always retains some degree of synchronization until it becomes totally unstable. This happens in two ways: in many cases for almost all initial conditions the solutions still approach a perfectly synchronized state. Even when this is not true, the attracting solutions are still synchronized, with a half-period phase shift. PMID:15006448

  5. Threshold stimulation and accommodation of the Hodgkin-Huxley axon.

    1992-02-01

    The charge-duration and strength-duration relations for just threshold rectangular stimuli were numerically investigated for the Hodgkin-Huxley axons of different lengths and different membrane capacitances under normal conditions and blockage of the development of accommodative processes. Two linear portions could be distinguished on the charge-duration curve. One of them followed the Weiss law. The other one represented a portion of a straight line passing through the zero point of the coordinates. The slope of the second portion was determined by the charge for very short stimuli (Q0), the slope of the first portion, and the maximum time to excitation (tau max). The rheobase reflected the slope of the second portion. Upon varying the fibre length the slope of the first and the second linear portions and the rheobase changed. The membrane capacitance substantially affected both the value of Q0 (as in the case of myelinated fibres) and the rheobase. The accommodative processes affected the Q0, the slope of the first line, tau max, and, consequently, the rheobase. The effect of potassium activation was stronger than that of sodium inactivation. The slope of the first line, tau max, and the rheobase might be considered more comprehensive indicators of the accommodative processes than the usually used indicators. PMID:1499981

    Moujahid, A; d'Anjou, A; Torrealdea, F J; Torrealdea, F

    2011-03-01

    The generation of spikes by neurons is energetically a costly process and the evaluation of the metabolic energy required to maintain the signaling 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 molecule of adenosine triphosphate (ATP) consumed, requires maximum energy consumption. 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 could be expected, the best performance occurs at a low energy cost. PMID:21517530

    A spiking neuron "computes" by transforming a complex dynamical input into a train of action potentials, or spikes. The computation performed by the neuron can be formulated as dimensional reduction, or feature detection, followed by a nonlinear decision function over the low-dimensional space. Generalizations of the reverse correlation technique with white noise input provide a numerical strategy for extracting the relevant low-dimensional features from experimental data, and information theory can be used to evaluate the quality of the low-dimensional approximation. We apply these methods to analyze the simplest biophysically realistic model neuron, the Hodgkin-Huxley (HH) model, using this system to illustrate the general methodological issues. We focus on the features in the stimulus that trigger a spike, explicitly eliminating the effects of interactions between spikes. One can approximate this triggering "feature space" as a two-dimensional linear subspace in the high-dimensional space of input histories, capturing in this way a substantial fraction of the mutual information between inputs and spike time. We find that an even better approximation, however, is to describe the relevant subspace as two dimensional but curved; in this way, we can capture 90% of the mutual information even at high time resolution. Our analysis provides a new understanding of the computational properties of the HH model. While it is common to approximate neural behavior as "integrate and fire," the HH model is not an integrator nor is it well described by a single threshold. PMID:14511510

    Pruritus is a common manifestation of Hodgkin lymphoma (HL), and given its high frequency, inclusion of itching as a B symptom of HL has been proposed. We present a 16-year-old adolescent boy with treatment-refractory eczema of 2 years' duration. Physical examination revealed a thin adolescent boy with widespread excoriations, but no eczematous or primary cutaneous lesions were identifiable. Lymph node examination revealed palpably enlarged nodes in the cervical and supraclavicular regions. Laboratory studies revealed leukocytosis and an elevated lactate dehydrogenase level. Diffuse lymphadenopathy was detected on a chest radiograph, and excisional lymph node biopsy revealed HL (nodular sclerosing subtype). The patient was classified as HL stage IIIB (Ann Arbor staging classification) after further evaluation. Chemotherapy was initiated followed by radiation therapy. The patient's pruritus markedly improved within 2 cycles of chemotherapy; however, his HL relapsed and additional salvage combination chemotherapy followed by high-dose chemotherapy and autologous stem cell transplant were required. This case underscores the need for a complete history as well as a careful skin and systemic evaluation in patients presenting with long-term pruritus, including children and adolescents.

    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.

    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.

    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.

    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

    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.

    From 1969 to 1982, 183 patients with previously untreated stages IIIB and IV Hodgkin's disease and relapsing Hodgkin's disease after radiation therapy were treated with combination chemotherapy plus low-dose irradiation (CRT). One hundred fifty patients who achieved a complete response (CR) were analyzed for risk of developing a second neoplasm. Median follow-up has been 8.3 years. Actuarial survival of all patients is 74% at 10 years with a relapse-free survival of 68%. An additional 24 patients with stage IIIA disease were also treated with CRT. There were 22 CRs at risk who were analyzed. Median follow-up has been 3+ years with an actuarial survival of 90% at five years and a relapse-free survival of 83%. Second neoplasms have developed in 14 of 172 patients at risk: acute nonlymphocytic leukemia (ANLL; five patients); aggressive histology non-Hodgkin's lymphoma (NHL; three patients); and a variety of solid neoplasms (six patients). Time to second neoplasm diagnosis after initial treatment ranged from 12 to 141 months. Five patients were older than 40 years. At the time of diagnosis of the second malignancy, 11 patients were free of Hodgkin's disease (for 36 to 141 months) and three were receiving therapy for recurrent Hodgkin's disease. The 10-year actuarial risk (%) of developing ANLL was 5.9 +/- 2.8; for NHL, the risk was 3.5 +/- 2.4, and for solid neoplasms, 5.8 +/- 3.0. Our results suggest that combination chemotherapy plus low-dose irradiation does not appear to significantly increase the risk of developing second neoplasms above that already reported for combination chemotherapy when administered as either initial or salvage treatment of Hodgkin's disease.

    2004-05-01

    The spinor formulation of classical dynamics, which arises naturally in Clifford algebra approaches, describes particle dynamics in terms of spinor amplitudes and gives quantum mechanical, spin-1/2 form to many classical expressions for particles whose dynamics can be represented by single spinor fields. Here we use tensor products of the algebra of physical space (APS)[1] to explore the quantum/classical interface and provide insight into quantum properties and, in particular, entanglement in multiparticle spin-1/2 systems. Entanglement in mixed-state systems is seen as spinor (Â"quantumÂ") correlation beyond the maximum possible with classical frequencies or probabilities. The relevance to systems of qubits in a quantum computer is elaborated. [1] W. E.

    Coherent control of a quantum mechanical two-level system is at the heart of magnetic resonance imaging, quantum information processing, and quantum optics. Among the most prominent phenomena in quantum coherent control are Rabi oscillations, Ramsey fringes, and Hahn echoes. We demonstrate that these phenomena can be derived classically by use of a simple coupled-harmonic-oscillator model. The classical problem can be cast in a form that is formally equivalent to the quantum mechanical Bloch equations with the exception that the longitudinal and the transverse relaxation times (T1 and T2) are equal. The classical analysis is intuitive and well suited for familiarizing students with the basic concepts of quantum coherent control, while at the same time highlighting the fundamental differences between classical and quantum theories.

    A 47-yr-old man developed dysphagia 4 yr after mediastinal radiotherapy for Hodgkin's disease. X-ray series, fiberoptic endoscopy, and computerized transverse tomography showed mucosal bridges in the upper esophagus. Histologically, these bridges were constituted from normal epithelium overlying a chronic inflammatory lamina propria, without evidence of Hodgkin's disease recurrence or of squamous cell carcinoma. Swallowing was improved by endoscopic electrocoagulation and Eder-Puestow dilatations. Several arguments favor the hypothesis that these mucosal bridges were the late sequelae of radiation esophagitis.

    This study examines the immunohistologic profiles of a large series of histologically proven benign and malignant lymphoproliferative processes in order to define immunophenotypic criteria useful in the diagnosis of non-Hodgkin's lymphoma. Using a method of analysis relying solely on immunoarchitectural features of a given case, the authors were able to define immunologic criteria capable of differentiating benign from malignant lymphoid processes independent from conventional morphologic analysis. In general, these criteria involved identification of abnormal expression or loss of antigens in B- and T-lineage populations. Among B-lineage populations the following features were associated with malignant histology: 1) light-chain-restricted B lineage, 2) light chain -B lineage, 3) Leu-1+ B lineage, 4) L60+ B lineage, 5) 41H+, Ki-67+ B lineage, 6) loss of pan-B antigens, and 7) LFA-1-B lineage. Among T-cell populations outside the thymus, phenotypes associated with malignancy included 1) loss of pan-T antigens (including loss of the beta chain of the T-cell antigen receptor), 2) coexpression or loss of T-subset antigens, 3) Leu-6+ T-lineage, and 4) MB-1+ T lineage. Application of these criteria to a series of nearly 500 cases of lymphoma indicated that over 90% of B-lineage and about 80% of T-lineage neoplasms manifested immunophenotypic abnormalities that could distinguish them from benign, reactive lymphoid processes. It is concluded that immunophenotypic analysis of lymphoproliferative lesions is sufficiently sensitive and specific to confirm the histologic diagnosis of lymphoma in the vast majority of cases seen in clinical practice. Furthermore, in difficult cases or those with limited material or poor histology, immunophenotypic analysis may be the only means of making a definitive diagnosis.

    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

  11. Pituitary infiltration by non-Hodgkin's lymphoma: a case report

    PubMed Central

    2009-01-01

    Introduction Pituitary adenomas represent the most frequently observed type of sellar masses; however, the presence of a rapidly growing sellar tumor, diabetes insipidus, ophthalmoplegia and headaches in an older patient strongly suggests metastasis to the pituitary. Since the anterior pituitary has a great reserve capacity, metastasis to the pituitary and pituitary involvement in lymphoma are usually asymptomatic. Whereas diabetes insipidus is the most frequent symptom, patients can present with headaches, ophthalmoplegia and bilateral hemianopsia. Case presentation A 70-year-old woman with no previous history of malignancy presented with headaches, right oculomotor nerve palsy and diabetes insipidus. As magnetic resonance imaging revealed a sellar mass involving the pituitary gland and infundibular stalk, which also extended into the right cavernous sinus and sphenoid sinus, the patient underwent an immediate transsphenoidal decompression surgery. Her prolactin was 102.4 ng/ml, whereas her gonadotropic hormone levels were low. A low level of urine osmolality after overnight water deprivation, along with normal plasma osmolality suggested diabetes insipidus. Histological examination revealed that the mass had been the infiltration of a high grade B-cell non-Hodgkin's lymphoma involving respiratory system epithelial cells. Paranasal sinus computed tomography scanning and magnetic resonance imaging of the thorax and abdomen were performed. Since magnetic resonance imaging did not reveal any abnormality, after paranasal sinus computed tomography was performed, we concluded that the primary lymphoma originated from the sphenoid sinus and infiltrated the pituitary. Chemotherapy and radiotherapy to the sellar area were planned, but the patient died and her family did not permit an autopsy. Conclusion Lymphoma infiltration to the pituitary is difficult to differentiate from pituitary adenoma, meningioma and other sellar lesions. To plan the treatment of lymphoma infiltration of the pituitary gland, it must be differentiated from other sellar lesions. PMID:20062782

  12. Chinese Constellations and Star Maps

    NASA Astrophysics Data System (ADS)

    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.

    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

    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.

    Although mediastinal involvement by Hodgkin's disease is frequent, the initial presentation of the lymphoma by an endobronchial lesion is rare. Therefore, the question of whether patients with Hodgkin's disease should undergo fibreoptic bronchoscopy as a staging procedure remains unresolved. In a series of 469 patients with newly diagnosed Hodgkin's disease during a 10 year period, we reviewed the clinical features of nine patients who presented with an endobronchial tumour. They were compared to 34 previously published cases. The major presenting symptoms were cough, wheezing and haemoptysis. Bulky mediastinum was seen in six cases. The three other patients presented respiratory symptoms evocative of endoluminal invasion. All but one of the patients received combined modality therapy, as currently accepted for patients with poor prognostic factors. The overall actuarial survival was 74% after 4 yrs of follow-up. A selective subgroup of patients with stage I-II supradiaphragmatic and endobronchial Hodgkin's disease may, thus, present without poor prognostic factors (but generally with respiratory symptoms), and might be undertreated if this localization is not recognized. We propose that these patients should undergo fibreoptic bronchoscopy. PMID:7828696

    Hodgkin-Reed Sternberg cells are derived from germinal centre B-cells in most cases. Somatic mutations affecting their rearranged immunoglobulin genes were detected, rendering potential functional rearrangements non-functional. Under physiological conditions such cells would be designated to undergo apoptosis within the germinal centre. In search for the specific transforming event that prevents Hodgkin-Reed Sternberg cells from programmed cell death, cytogenetic analyses were broadly performed but did not reveal specific chromosomal aberrations. Analysis of these cells on the molecular level is difficult to perform due to the scarcity of the cells in the lymphoma tissue and the given limitations of in situ studies. To overcome these limitations, the cell line L1236, known to be derived from Hodgkin-Reed Sternberg cells in situ, was chosen for allelotype analysis. Using a panel of microsatellite loci assigned to nearly all chromosomal arms, regions of loss of heterozygosity were detected on chromosomal arms 6p, 9q and 17p. The size of lost segments was estimated by amplification of additional microsatellite loci mapped to the respective regions. Further analyses of single Hodgkin-Reed Sternberg cells will reveal whether LOH affecting these regions is a recurrent event in HD and to which extent the smallest commonly affected region can be estimated. © 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11161403

    Introduction Primary central nervous system (CNS) involvement of Hodgkin's lymphoma is very uncommon. There are only a few previous reports of Hodgkin's lymphoma of nodular lymphocyte predominant histology involving the CNS concurrently with systemic disease. Case presentation A 12-year-old boy with a history of painless left inguinal swelling and acute diplopia. There was an intensely enhancing lesion in the right midbrain on magnetic resonance imaging. The patient was diagnosed with stage IV Hodgkin's lymphoma of nodular lymphocyte predominance type by routine microscopy and immunohistochemistry of left inguinal lymph node biopsy with computed tomography-assisted staging. It was planned to treat him with six cycles of chemotherapy with intrathecal methotrexate, followed by radiotherapy to the CNS lesions. After two cycles of chemotherapy, the patient entered complete remission of all lesions including the CNS lesion documented by the positron emission tomography scan. Conclusion We are describing the course of this rare presentation of Hodgkin's lymphoma of nodular lymphocyte predominant histology involving the CNS and clinical challenge in its diagnosis and management of this case.

    The recent WHO classification of non-Hodgkin's lymphoma is based on the morphology and immunohistochemical expression of the lymphoma cells and to a lesser extent, on the molecular and cytogenetic findings. Fifty-three cases of non-Hodgkin's lymphoma were included in the study. Of these, seven cases were primary extra nodal lymphomas. Twenty two patients had peripheral blood and/or bone marrow involvement. A detailed morphological assessment was done and classified using the International working formulation. The two most common types encountered were diffuse large cell lymphoma and small lymphocytic lymphoma. Immunohistochemistry was done using labeled streptavidin-biotin peroxidase complex with CD3, CD20, CD15, CD30, CD 45 (leukocyte common antigen), Cyclin D1, EMA (epithelial membrane antigen). 38 cases (72%) showed B cell expression and 12 cases (22.5%) showed T cell expression. Three cases did not express either marker. B-cell diffuse large cell lymphoma (26%) was found to be the predominant B cell non-Hodgkin's lymphoma. The commonest T-cell lymphoma was T lymphoblastic lymphoma (67%) followed by peripheral T cell angioimmunoblastic lymphoma (25%). Immunohistochemistry is a useful and necessary diagnostic modality and helps subdivide prognostically different types of non-Hodgkin's lymphoma. PMID:16933715

    Higher mortality rates are reported because of cardiovascular diseases in individuals living in industrialized areas of the World. In cancer patients, cardiotoxic chemotherapeutic agents and/or mediastinal radiotherapy are additional risk factors for the development of coronary artery disease. An improved survival rate for patients with Hodgkin lymphoma was reported in recent decades. Determining and handling the long-term effects of cancer treatment have become more important nowadays, parallel to the good results reached in survival rates. Mediastinal radiotherapy and cardiotoxic chemotherapeutic agents are routinely used to treat Hodgkin lymphoma but are commonly associated with a variety of cardiovascular complications. Drugs used in cancer treatment and radiotherapy may cause deleterious effects on contractile capacity and conduction system of the heart. Approximately ten years after the completion of all therapies, the cardiovascular disease risk peaks in patients who survived from Hodgkin lymphoma. The value of coronary computed tomography angiography as a diagnostic tool in determining coronary artery disease as early as possible is underlined in this review, in patients who are in remission and carry the risk of coronary artery disease probably because of chemo/radiotherapy used in their treatment. Survivors of Hodgkin lymphoma especially treated with combined chemoradiotherapy at younger ages are candidates for coronary computed tomography angiography. PMID:25068016

    The multicolor and multiplexing capabilities of semiconductor quantum dots (QDs) are most promising for improving the sensitivity and specificity of in vitro molecular and cellular diagnostics. Here, we report the use of multiplexed QDs and wavelength-resolved imaging to detect and characterize a class of low-abundant tumor cells in Hodgkin's lymphoma. Known as the Hodgkin's and Reed-Sternberg (HRS) cells, this class of malignant cells is a pathological hallmark in clinical diagnosis, but it comprises only about 1% of the heterogeneous infiltrating cells in lymph node tissues. To overcome this cellular heterogeneity and rarity problem, we have developed multicolor QD-antibody conjugates to simultaneously detect a panel of four protein biomarkers (CD15, CD30, CD45, and Pax5) directly on human tissue biopsies. This multiplexing approach allows rapid detection and differentiation of rare HRS cells from infiltrating immune cells such as T and B lymphocytes. We have also carried out clinical translation studies involving six confirmed Hodgkin's lymphoma patients, two suspicious lymphoma cases, and two patients with reactive lymph nodes (but not lymphoma). The results indicate that a distinct QD staining pattern (CD15 positive, CD30 positive, CD45 negative, and Pax5 positive) can be used to not only detect Hodgkin's lymphoma but also differentiate it from benign lymphoid hyperplasia.

  14. 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.

    We seek an analogy of the mathematical form of the alternative form of Einstein's field equations for Lovelock's field equations. We find that the price for this analogy is to accept the existence of the trace anomaly of the energy-momentum tensor even in classical treatments. As an example, we take this analogy to any generic second order Lagrangian and exactly derive the trace anomaly relation suggested by Duff. This indicates that an intrinsic reason for the existence of such a relation should perhaps be, classically, somehow related to the covariance of the form of Einstein's equations.

    Background The efficacy of autologous stem-cell transplantation during the first remission in patients with diffuse, aggressive non-Hodgkin's lymphoma classified as high-intermediate risk or high risk on the International Prognostic Index remains controversial and is untested in the rituximab era. Methods We treated 397 patients who had disease with an age-adjusted classification of high risk or high-intermediate risk with five cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP plus rituximab. Patients with a response were randomly assigned to receive three additional cycles of induction chemotherapy (control group) or one additional cycle of induction chemotherapy followed by autologous stem-cell transplantation (transplantation group). The primary efficacy end points were 2-year progression-free survival and overall survival. Results Of 370 induction-eligible patients, 253 were randomly assigned to the transplantation group (125) or the control group (128). Forty-six patients in the transplantation group and 68 in the control group had disease progression or died, with 2-year progression-free survival rates of 69 and 55%, respectively (hazard ratio in the control group vs. the transplantation group, 1.72; 95% confidence interval [CI], 1.18 to 2.51; P = 0.005). Thirty-seven patients in the transplantation group and 47 in the control group died, with 2-year overall survival rates of 74 and 71%, respectively (hazard ratio, 1.26; 95% CI, 0.82 to 1.94; P = 0.30). Exploratory analyses showed a differential treatment effect according to risk level for both progression-free survival (P = 0.04 for interaction) and overall survival (P = 0.01 for interaction). Among high-risk patients, the 2-year overall survival rate was 82% in the transplantation group and 64% in the control group. Conclusions Early autologous stem-cell transplantation improved progression-free survival among patients with high-intermediate-risk or high-risk disease who had a response to induction therapy. Overall survival after transplantation was not improved, probably because of the effectiveness of salvage transplantation. PMID:24171516

    2011-01-01

    Conductance-based equations for electrically active cells form one of the most widely studied mathematical frameworks in computational biology. This framework, as expressed through a set of differential equations by Hodgkin and Huxley, synthesizes the impact of ionic currents on a cell's voltage—and the highly nonlinear impact of that voltage back on the currents themselves—into the rapid push and pull of the action potential. Later studies confirmed that these cellular dynamics are orchestrated by individual ion channels, whose conformational changes regulate the conductance of each ionic current. Thus, kinetic equations familiar from physical chemistry are the natural setting for describing conductances; for small-to-moderate numbers of channels, these will predict fluctuations in conductances and stochasticity in the resulting action potentials. At first glance, the kinetic equations provide a far more complex (and higher-dimensional) description than the original Hodgkin-Huxley equations or their counterparts. This has prompted more than a decade of efforts to capture channel fluctuations with noise terms added to the equations of Hodgkin-Huxley type. Many of these approaches, while intuitively appealing, produce quantitative errors when compared to kinetic equations; others, as only very recently demonstrated, are both accurate and relatively simple. We review what works, what doesn't, and why, seeking to build a bridge to well-established results for the deterministic equations of Hodgkin-Huxley type as well as to more modern models of ion channel dynamics. As such, we hope that this review will speed emerging studies of how channel noise modulates electrophysiological dynamics and function. We supply user-friendly MATLAB simulation code of these stochastic versions of the Hodgkin-Huxley equations on the ModelDB website (accession number 138950) and http://www.amath.washington.edu/~etsb/tutorials.html.

    Classical galactosaemia (McKusick 230400) is an: autosomal recessive disorder of galactose metabolism, caused by a deficiency of the enzyme galactose-1-phosphate uridyltransferase (GALT; EC 2.7.712). Most patients present in the neonatal period, after ingestion of galactose, with jaundice, hepatosplenomegaly, hepatocellular insufficiency, food intolerance, hypoglycaemia, renal tubular dysfunction, muscle hypotonia, sepsis and cataract. The gold standard for diagnosis of classical galactosaemia is measurement of GALT activity in erythrocytes. Gas-chromatographic determination of urinary sugars and sugar alcohols demonstrates elevated concentrations of galactose and galactitol. The only therapy for patients with classical galactosaemia is a galactose-restricted diet, and initially all galactose must be removed from the diet as soon as the diagnosis is suspected. After the neonatal period, a lactose-free diet is advised in most countries, without restriction of galactose-containing fruit and vegetables. In spite of the strict diet, long-term complications such as retarded mental development, verbal dyspraxia, motor abnormalities and hypergonadotrophic hypogonadism are frequently seen in patients with classical galactosaemia. It has been suggested that these complications may result from endogenous galactose synthesis or from abnormal galactosylation. Novel therapeutic strategies, aiming at the prevention of galactose 1-phosphate production, should be developed. In the meantime, the follow-up protocol for patients with GALT deficiency should focus on early detection, evaluation and, if possible, early intervention in problems of motor, speech and cognitive development.

    CD99 is a 32-kDa transmembrane glycoprotein that is encoded by the MIC2 gene. Our study was carried out to examine the role of CD99 in tumor progression of classical Hodgkin lymphoma (cHL). Here, we showed that lowly expressed CD99 protein in cHL cell lines and primary cHL cases correlates with the deficient expression of the positive regulatory domain 1 (PRDM1/BLIMP1). In addition, cHL cell lines showed high levels of miR-9 expression. We determined that the upregulation of CD99 induced expression of transcription factor PRDM1, a master regulator of plasma-cell differentiation, which is also a target for miR-9-mediated downregulation. Indeed, inhibition of miR-9 also triggered upregulation of PRDM1 expression. Furthermore, overexpression of CD99 resulted in changed growth features and reorganization of actin cytoskeleton. As upregulation of CD99 led to a decrease in cHL diagnosis marker CD30 and CD15 and an increase in plasma-cell differentiation marker CD38 and the restoration of B-cell makers PAX5, CD79? and CD19, we suggest that downregulated CD99 leads to the prevention of plasma-cell differentiation in Hodgkin/Reed-Sternberg (H/RS) cells. Furthermore, these data indicate that CD99 may control miR-9 expression, which directly targets PRDM1. Altogether, these results reveal a CD99-miR-9-PRDM1 molecule axis in lymphomagenesis of cHL and suggest that upregulation of CD99 in H/RS cells induces terminal B-cell differentiation, which may provide a novel therapeutic strategies for cHL.

  8. Quantum particles from classical statistics

    2010-02-11

    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.

    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

    Large B-cell non-Hodgkin lymphoma involving the prostate accounts for 0.09% and 0.1% of non-Hodgkin lymphoma. We report a case of prostatic large B-cell non-Hodgkin lymphoma in a 77-year-old male with symptoms of urinary retention most probably due to benign prostate hyperplasia. He underwent multiple needle core biopsies through transrectal ultrasound of the prostate. Histopathological examination of the core biopsies revealed diffuse infiltration by atypical lymphoid cells in the prostatic stroma, which was strongly positive for leukocyte common antigen and CD20. CD3, CK, PSA, BCL2, k-light chain, Cyclin D1 and synaptophysin were negative. Histopathology and immunohistochemical profile in the case was consistent with the diagnosis of diffuse large B-cell non-Hodgkin lymphoma of the prostate. PMID:25657557

    A small percentage of patients treated for Hodgkin's disease are at risk of developing a second malignancy. The appearance of secondary malignancies such as leukemia, carcinoma or non-Hodgkin's lymphomas may be attributed to the mutagenic effects of chemotherapy and/or radiotherapy. Most secondary non-Hodgkin's lymphomas are of the B-cell type, but isolated cases were reportedly of a T-cell lineage. A review of the literature pertaining to the development of secondary peripheral T-cell lymphomas is presented along with the description of an additional case. The latter developed in the tonsil and was diagnosed as a Lennert's lymphoma (lymphoepithelioid T cell lymphoma)on histological and immunological grounds.

    This study analysed HLA class 1 and 2 allele associations in Singaporean Chinese patients with RA. Seventy patients (ARA definite or classical) and 80 controls were typed for HLA class 1 alleles by serology and class 2 alleles by serology and the PCR/SSO method. RA patients had higher frequencies of DRB1*0405 (40 vs 12.5%; corrected probability value (PC) < 0.02, relative risk (RR) = 4.7, 95% confidence limit (CL) 2.1-10.6), DRB1*1001 (14.3 vs 1.3%; PC = 0.06, RR = 13.2, 95% CL 1.6-105.7), DQB1*0401 (38.6 vs 12.5%; P = 0.006, RR = 4.4, 95% CL 1.9-10.0) and DQB1*0501 (20 vs 5%; PC = 0.048, RR = 4.8, 95% CL 1.5-15.2). It is concluded that Chinese RA is associated primarily with HLA DRB1*0405 and DRB1*1001 which share common amino acid sequences in the third hypervariable region of the DR beta chains shown to be associated with RA in other ethnic groups. Patients without DRB1*0405 and *1001 had a higher frequency of DRB1*0901, which is in linkage disequilibrium with HLA B46 in the Chinese. PMID:8055196

    ABVD regimen (doxorubicin, bleomycin, vinblastine and dacarbazine) remains the most commonly used front-line therapy for Hodgkin lymphoma. However, atypical and extranodal presentations present challenges to initial therapy, especially in the presence of renal and liver failure. We hereby present two cases of young male patients with atypical presentation of Hodgkin lymphoma with severe abnormal liver function. Patients showed excellent response to cyclophosphamide, etoposide, procarbazine and prednisone (CEPP regimen). PMID:24991411

    Following the line of the history, if by one side the electromagnetic theory was consolidated on the 19th century, the emergence of the special and the general relativity theories on the 20th century opened possibilities of further developments, with the search for the unification of the gravitation and the electromagnetism on a single unified theory. Some attempts to the geometrization of the electromagnetism emerged in this context, where these first models resided strictly on a classical basis. Posteriorly, they were followed by more complete and embracing quantum field theories. The present work reconsiders the classical viewpoint, with the purpose of showing that in a first order of approximation the electromagnetism constitutes a geometric structure aside other phenomena as gravitation. Even though being limited, the model is consistent and offers the possibility of an experimental test of validity.

  20. Classical Language Instruction Project

    NSDL National Science Digital Library

    Developed by Christian Wildberg at Princeton University, the Classical Language Instruction Project is designed to function as a resource for college undergraduates hoping to gain some insight into the pronunciation and elocution of ancient Greek and Latin. As the rationale for the Project states on the site: "There may be considerable debate among scholars about the most 'authentic' way to pronounce Greek or Latin; yet it is certain that the texts from the ancient world reflect a vivid and complex spoken language, not a lifeless code." With that in mind, the site features different classical scholars reading passages by a number of writers, including Homer, Plato, Virgil, Horace, Ovid, and Seneca. As the scholars read, students can follow along, view the passage in English, and pause the recording in order to develop an understanding of the text and its pronunciation. Finally, the site also includes a brief essay on rhythm and meter in Greek and Latin.

  1. Origin of Classical Singularities

    We briefly review some results concerning the problem of classical singularities in general relativity, obtained with the help of the theory of differential spaces. In this theory one studies a given space in terms of functional algebras defined on it. Then we present a generalization of this method consisting in changing from functional (commutative) algebras to noncommutative algebras. By representing such an algebra as a space of operators on a Hilbert space we study the existence and properties of various kinds of singular space-times. The obtained results suggest that in the noncommutative regime, supposedly reigning in the pre-Planck era, there is no distinction between singular and non-singular states of the universe, and that classical singularities are produced in the transition process from noncommutative geometry to the standard space-time physics.

    A number of neoplastic disorders are characterized by recurrent chromosome aberrations. One of these is the translocation t(2;5), which is found in a considerable percentage of large-cell anaplastic lymphomas. This translocation results in the fusion of two genes, alk and npm. The recent discovery of alk/npm mRNA in 11 of 13 cases of Hodgkin's disease has caused a controversial discussion concerning the question of whether t(2;5) is also present in Hodgkin and Reed-Sternberg cells. We tackled this problem on the molecular cytogenetic level by combined CD30 immunophenotyping and interphase cytogenetics. Using a pair of DNA probes flanking both sides of the npm gene breakpoint at 5q35 we were able to prove, at least in 12 of 13 cases of Hodgkin's disease, that all CD30-positive Hodgkin and Reed-Sternberg cells lacked the translocation t(2;5). Fifteen to forty-five Hodgkin/Reed-Sternberg cells were analyzed per case (mean, 27). Our findings indicate that this translocation is not a primary event in the development of Hodgkin's disease.

    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

    Tumor cells of classical Hodgkin lymphoma (cHL) are characterized by a general loss of B cell phenotype, whereas antigen presenting properties are commonly retained. HLA class I is expressed in most EBV+ cHL cases, with an even enhanced expression in a proportion of the cases. Promyelocytic leukemia protein (PML) and special AT-rich region binding protein 1 (SATB1) are two global chromatin organizing proteins that have been shown to regulate HLA class I expression in Jurkat cells. We analyzed HLA class I, number of PML nuclear bodies (NBs) and SATB1 expression in tumor cells of 54 EBV+ cHL cases and used 27 EBV? cHL cases as controls. There was a significant difference in presence of HLA class I staining between EBV+ and EBV? cases (p<0.0001). We observed normal HLA class I expression in 35% of the EBV+ and in 19% of the EBV? cases. A stronger than normal HLA class I expression was observed in approximately 40% of EBV+ cHL and not in EBV? cHL cases. 36 EBV+ cHL cases contained less than 10 PML-NBs per tumor cell, whereas 16 cases contained more than 10 PML-NBs. The number of PML-NBs was positively correlated to the level of HLA class I expression (p<0.01). The percentage of SATB1 positive cells varied between 0% to 100% in tumor cells and was inversely correlated with the level of HLA class I expression, but only between normal and strong expression (p<0.05). Multivariable analysis indicated that the number of PML-NBs and the percentage of SATB1+ tumor cells are independent factors affecting HLA class I expression in EBV+ cHL. In conclusion, both PML and SATB1 are correlated to HLA class I expression levels in EBV+ cHL. PMID:24009715

    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.

    This his article reports the findings of a study conducted to investigate the personality types of Chinese dental school applicants. The Chinese version of the Myers-Briggs Type Indicator (MBTI) (Form G) was used to assess the personality styles of 332 dental school applicants from the mainland of China. The results of the MBTI for Chinese dental school applicants were compared with a previous study of applicants from the U.K. A higher percentage of this group of Chinese applicants scored higher for Introversion (I) than Extroversion (E); both Chinese and English applicants preferred Judging (J) to Perceiving (P). The dominant personality types in Chinese applicants were ISTJ, ESTJ, and ISFP. The findings suggest that the personality types of Chinese dental students may be somewhat different from the personality profiles exhibited by dental students from other nations. The findings may be of value to individuals who desire to investigate personality type differences among dental students with different cultural backgrounds. PMID:18096885

    Some herbal drugs commonly used in Chinese medicine have been studied chemically in correlation with their biological activities. In many cases it has been recognized that some characteristic chemical constituents could represent the therapeutical actions of the drugs. It is noted that elucidation of their chemical structures in view of the structure-activity relationship provides scientific evidence for the beneficial uses of traditional drugs in health care and, furthermore, promotes the discovering of new therapeutics from them. The principles of Chinese drugs are distributed widely among almost all the chemical groups of natural products, for example, simple phenolics, lignan, flavonoid, quinonoid, lower terpenes, triterpenoid, steroid, true alkaloid, protoalkaloid or amines and simple and polymolecular carbohydrates. In the present article, the chemical principles of some important Chinese drugs currently used are discussed mainly on the basis of our own investigations, and we refer to other works for a general understanding of the present status on the chemical approach to studies of Chinese drugs and medicine.

    Although the adrenal glands are frequently the site of tumor metastases, adrenal insufficiency is exceedingly rare. We report on a patient with high-grade B-cell centroblastic lymphoma who initially presented with right axillary lymphadenopathy and bilateral adrenal masses. Four months after axillary lymphadenectomy the patient developed overt signs of Addison's disease. He recovered promptly after initiation of hormone replacement therapy and bilateral adrenalectomy. At present, 16 months after additional chemo- and radiation therapy the patient is considered free of tumor. To our knowledge this is the first report on a patient who presented with adrenal insufficiency in the course of non-Hodgkin's lymphoma and who was successfully treated. Demonstrating this case, we would also like to stress that the development of adrenal insufficiency does not necessarily indicate widespread tumor manifestation in patients with non-Hodgkin's lymphoma.

    Primary nonHodgkin's lymphoma of the testis is a localized disease in 50 per cent of the cases. Clinical records and pathological material from 9 stage IE cancer patients treated at our institutions were reviewed. All but 1 patient had B cell type lymphomas of intermediate (6) or high (3) grade according to the Working Formulation. Mean survival was 49 months and actuarial survival was 74 per cent at 5 years. Chemotherapy differed with time and frequently was associated with subdiaphragmatic involved field and prophylactic contralateral testis radiotherapy. In view of the good prognosis of patients receiving doxorubicin-based chemotherapy and recent reports on low stage nonHodgkin's lymphoma we recommend an aggressive brief therapy for stage IE lymphoma of the testis after orchiectomy.

    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.

    Immune thrombocytopenia complicates the course and impacts the outcome of non-Hodgkin lymphoma (NHL-ITP, non-Hodgkin lymphoma-immune thrombocytopenic purpura). The response to corticosteroids and/or intravenous immune globulins is usually short lasting, but NHL-ITP usually responds to anti-lymphoma chemotherapy. It is not clear if this success is due to the elimination of the lymphomatous tissue or to the immunosuppressor/immunomodulator effect of chemotherapy. Myelosuppressive anti-lymphoma chemotherapy carries the risk of severe thrombocytopenia that may not respond adequately to platelet transfusion support. We report on a patient with recurrent diffuse large B-cell lymphoma that coincided with immune thrombocytopenia. Both diseases completely responded to involved field radiation therapy. This supports the hypothesis that at least in some cases of NHL-ITP, the lymphomatous clone secretes the anti-platelet antibodies. This supports the therapeutic decision making for these patients.

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a subtype of Hodgkin lymphoma (HL), and is a rare disease manifestation in the adrenal gland, which is difficult to be diagnosed and treated. In the present study, we report a case of primary adrenal NLPHL in a 36-year-old male patient. The patient was without specific clinical signs and the definitive diagnosis was achieved by histological study. The patient underwent a laparoscopic left adrenalectomy and chemotherapy regimen of doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD). There is no standard treatment for adrenal NLPHL and therefore, treatment is based on that for other types of NLPHL, which includes radiotherapy and ABVD chemotherapy. Given the rarity of this disease, there are limited experiences with regard to its diagnosis and treatment. This study is useful for the differential diagnosis and treatment of adrenal masses.

  7. The what and where of adding channel noise to the Hodgkin-Huxley equations

    E-print Network

    2011-01-01

    One of the most celebrated successes in computational biology is the Hodgkin-Huxley framework for modeling electrically active cells. This framework, expressed through a set of differential equations, synthesizes the impact of ionic currents on a cell's voltage -- and the highly nonlinear impact of that voltage back on the currents themselves -- into the rapid push and pull of the action potential. Latter studies confirmed that these cellular dynamics are orchestrated by individual ion channels, whose conformational changes regulate the conductance of each ionic current. Thus, kinetic equations familiar from physical chemistry are the natural setting for describing conductances; for small-to-moderate numbers of channels, these will predict fluctuations in conductances and stochasticity in the resulting action potentials. At first glance, the kinetic equations provide a far more complex (and higher-dimensional) description than the original Hodgkin-Huxley equations. This has prompted more than a decade of effo...

    A cluster of Hodgkin's disease (HD) cases occurred in a small rural town of 1250 people. Ten cases of HD and three cases of non-Hodgkin's lymphoma were identified within or linked to this town since 1954. This town therefore had an average annual incidence and mortality for HD of 29.3 and 16.7 cases per 100,000 population, respectively. Most cases of HD demonstrated case-contact associations, and a distinct geographic distribution. The data suggested that there was an environmental agent responsible for the elevated rates of HD. One unique aspect of this cluster is that this town has only one industry, a large grain elevator. The cases closely surrounded this elevator. We postulate that residents of the town are subject to chronic immune stimulation from mitogenic substances in this environment. These agents may alter immunity in the residents of this community and predispose them to acquiring HD. PMID:685972

    Castleman disease (CD) is a benign heterogenous lymphoproliferative disorder presenting with varied clinical manifestations. Histomorphologically, two distinct variants are known, hyaline vascular type and plasma cell type. CD is reported to be associated with lymphomas. Though Non Hodgkin lymphoma is more commonly associated with CD, its association with Hodgkin lymphoma (HL) is also well known and documented. Many a times, CD obscures or masks the underlying lymphomas thus delaying the diagnosis. There are also reports of HL showing Castleman like features. We report a case of HL with Castleman like features which posed diagnostic difficulty owing to the fragmented nature and tiny size of the initial lymph node biopsy. Striking peripheral blood rouleaux formation which was seen in our case along with bone marrow plasmacytosis has not been described in the previously diagnosed cases. PMID:25332627

    Primary bilateral non-Hodgkin's lymphoma (NHL) of the adrenal gland is a very rare entity. Indeed less than 60 cases have been reported in the literature. Hence, we report a case of high-grade lymphoma of both adrenal glands that was found in a young patient of 32 years of age. The patient was admitted in the emergency department of our hospital with a profile of hemorrhagic shock. After stabilization, the imaging investigations demonstrated large bilateral adrenal masses. The CT-scan guided biopsy of both adrenal glands allowed the diagnosis of primary bilateral adrenal NHL. The patient died after the first chemotherapy session. The presence of bilateral adrenal masses associated with a rapid increase of volume should raise the diagnosis of primary adrenal non-Hodgkin's lymphoma. PMID:23304624

    Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine. In the face of poor diagnoses devices in most of the Mexican hospitals, we recommend the present diagnose stratification, and treatment guidelines for non-Hodgkin lymphoma, based on evidence. They include the latest and most innovative therapeutic approaches, as well as specific recommendations for hospitals with limited framework and therapy resources. PMID:24459777

    In this nested case-control study we examined the relationship between non-Hodgkin's lymphoma (NHL) and organochlorine pesticide exposure. We used a data set originally collected between 1969 and 1983 in the U.S. Environmental Protection Agency National Human Adipose Tissue Survey. Adipose samples were randomly collected from cadavers and surgical patients, and levels of organochlorine pesticide residues were determined. From the original

    A 22-year-old woman with Hodgkin lymphoma underwent a staging 18F-FDG PET/CT scan, which showed an intense uptake in the right proximal femur, in addition to FDG-avid mediastinal and cervical lymph nodes. The patient thus was diagnosed with stage IV lymphoma with bone marrow involvement. Postchemotherapy restaging scan showed complete resolution of nodal uptake but persistent activity in the right femur. Radiography and biopsy confirmed liposclerosing myxofibrous tumor.

    The pattern of adolescent\\/young adult Hodgkin lymphoma (YAHL) suggests cau- sation by a relatively late infection with a common childhood virus, but no causal virus has been found. Susceptibility is heritable and linked to lower interleukin 12 (IL12) levels, which can also result from fewer fecal-oral microbial ex- posures early in life. We studied twin pairs discordant for YAHL to
