Abstract
Caseous lymphadenitis (CL) is a chronic contagious disease that affects small ruminants and is characterized by the formation of pyogranulomas in lymph nodes and other organs. However, the pathogenesis of this disease and the response of the host genome to infection are not yet fully understood. This study aimed to investigate the whole blood transcriptome and evaluate differential gene expression during the later stages of CL in naturally infected ewes. The study included diseased, serologically positive (EP), exposed, serologically negative (EN) ewes from the same infected flock and healthy ewes (CN) from a different flock. RNA sequencing was performed using the Illumina NextSeq system, and differential gene expression was estimated using DESeq2 and Edge R approaches. The analysis identified 191 annotated differentially expressed genes (DEGs) in the EP group (102 upregulated and 89 downregulated) and 256 DEGs in the EN group (106 upregulated and 150 downregulated) compared to the CN group. Numerous immunoregulatory interactions between lymphoid and nonlymphoid cells were influenced in both EP and EN ewes. Immune DEGs were preferentially assigned to antigen presentation through the MHC complex, T lymphocyte-mediated immunity, and extracellular matrix interactions. Furthermore, the EP group showed altered regulation of cytokine and chemokine signaling and activation and recombination of B-cell receptors. Conversely, NF-kappa B signaling, apoptosis, and stress response were the main processes influenced in the EN group. In addition, statistically significant enrichment of the essential immune pathways of binding and uptake of ligands by scavenger receptors in EP and p53 signaling in the EN group was found. In conclusion, this study provides new insights into the disease course and host-pathogen interaction in naturally CL-infected sheep by investigating the blood transcriptome.

Abstract
Bats may carry various viruses and bacteria which can be harmful to humans, but little is known about their role as a parasitic source with zoonotic potential. The aim of this study was to test wild bats for the presence of selected parasites: Toxoplasma gondii, Neospora caninum and microsporidia Encephalitozoon spp. In total, brain and small intestine tissues of 100 bats (52 Myotis myotis, 43 Nyctalus noctula and 5 Vespertilio murinus) were used for the DNA isolation and PCR detection of the abovementioned agents. Toxoplasma gondii DNA was detected by real-time PCR in 1% of bats (in one male of M. myotis), while all bats were negative for N. caninum DNA. Encephalitozoon spp. DNA was detected by nested PCR in 25% of bats, including three species (twenty-two M. myotis, two N. noctula and one V. murinus). Positive samples were sequenced and showed homology with the genotypes Encephalitozoon cuniculi II and Encephalitozoon hellem 2C. This is the first study on wild vespertilionid bats from Central Europe and worldwide, with a relatively high positivity of Encephalitozoon spp. detected in bats.

Abstract
The aim of this study was to determine the seroprevalence of antibodies to B. burgdorferi s.l. in wild small mammals in the Czech Republic and compare sensitivity of PCR and cultivaton. Wild small mammals (n = 691) were trapped in years 2010-2014 in three localities of the Czech Republic. Heart rinses (n = 340) and sera (n = 351) were examined by modified indirect ELISA. Seventy animals were randomly selected for comparison of results of cultivation and PCR. Mean annual antiborelian positivity was 12% with statistical difference (p < 0.05) between Bank Vole (Clethrionomys glareolus) and other six animal species, while there was no statistical difference (p > 0.05) between rodentia and insectivora, gender and localities. The cultivation revealed one positive sample (1.4%), negative in both PCR and ELISA. Method PCR revealed seven positive samples (10%); two of them were simultaneously dubious in ELISA. Eleven animals, negative in cultivation and PCR, had antibodies in ELISA. Method of PCR compared to cultivation seems to be more sensitive for detection of Borrelia.

Abstract
High-dose chemotherapy with autologous stem cell transplantation remains the current standard of treatment for young patients with Hodgkin lymphoma in first relapse or in those who are refractory to first-line treatment. The most important prognostic factors in relapses are clinical stage IV, poor performance status, bulky mass, and less than partial remission after salvage chemotherapy. Standard salvage chemotherapy in relapse before autologous transplantation has not been defined; however, DHAP and ICE are most frequently used in this setting. A standard conditioning regimen before autologous transplantation is BEAM. Tandem autologous transplantation has been investigated in high-risk patients. Brentuximab vedotin is recommended as a consolidation treatment in patients with a high risk of relapse after autologous transplantation. Brentuximab vedotin is the standard of treatment for relapse after autologous transplantation, and subsequent allogeneic stem cell transplantation should be considered in young patients. Bretuximab vedotin in combination with bendamustine, nivolumab, and pembrolizumab, and combinations thereof with other drugs, were investigated in clinical trials in relapsed or refractory patients with Hodgkin lymphoma.Key words: Hodgkin lymphoma - autologous stem cell transplantation - brentuximab vedotin - nivolumabThis work was supported by grant awarded by AZV 16-29857, Ministry of Health in Czech Republic, Research project P 27/2012 awarded by Charles University in Prague, 3rd Faculty of Medicine, Prague.The authors declare they have no potential confl icts of interest concerning drugs, products, or services used in the study.The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.Submitted: 7. 6. 2016Accepted: 24. 8. 2016.

Abstract
BACKGROUND Cognitive impairment (impairment of memory, attention, or concentration) is documented in 17-75% of patients with various malignancies treated with chemotherapeutic agents that worsen quality of life. CRCI affects patients of all ages. The impairment of cognitive function in connection with chemotherapy is usually mild, but an event. relationship with dementia remains to be confirmed. Chemotherapy in combination with radiotherapy in Hodgkin lymphoma can cure 80-90% of patients. AIM This review summarizes the most frequently observed changes in cognitive function in patients suffering from CRCI. The article further describes the possible pathophysiological mechanisms behind these changes and the risk factors that can increase the likelihood of cognitive functional impairment after chemotherapy of malignant tumors. Special attention is given to how this relates to Hodgkins lymphoma. We also discuss the neuroprotective factors involved in chemotherapy-related cognitive impairment and its treatment options. CONCLUSION Changes occur mainly in the ability to learn and remember, in the speed of reactions, and in attention and executive functions. Although CRCI pathophysiological mechanisms are complex and not yet fully understood, the involvement of neurotoxicity, such as that induced by treatment, anemia, higher levels of oxidative stress and inflammatory responses, genetic factors, and reduced brain connectivity is discussed. CRCI is further modified by comorbidities and patient age. Pharmacological and nonpharmacological treatment options for CRCI are outlined.Key words: Hodgkin lymphoma - chemotherapy - cognitive impairment - risk factors The project was supported by the grant of the Agency for the Czech Republic Health Research of the Ministry of Health of the Czech Republic 16-29857A and by the project Sustainability for the National Institute of Mental Health No. LO1611 with a financial support of the Ministry of Education, Youth and Sports of the Czech Republic in the frame of the National Sustainability Programme I.

Abstract
INTRODUCTION AND OBJECTIVES Encephalitozoon cuniculi is an obligate intracellular parasite infecting especially domestic rabbits; however, spontaneous infections have been documented in other mammalian species such as dogs, cats, rabbits, horses, cows and sheep all over the world. Encephalitozoonosis is a chronic and latent disease leading to renal failure, encephalitis, disorders of brain and urinary tract, and may lead to death. There are limited reports on encephalitozoonosis in wildlife, which is why the aim of this study was to detect the prevalence of antibodies to E. cuniculi in European hares. MATERIALS AND METHODS Samples of blood sera from 701 wild hares from the Czech Republic (n = 245), the Slovak Republic (n = 211) and Austria (n = 245) were examined by indirect immunofluorescence antibody test (IFAT); samples with titer ≥ 40 were marked as positive. RESULTS The total seroprevalence of E. cuniculi antibodies was 1.42% with titres in the range 40-640. Antibodies to E. cuniculi were detected in 2.9% (7/245), 0.8% (2/245) and 0.47% (1/211) hares from the Czech Republic, Austria and the Slovak Republic, respectively. CONCLUSIONS This is the first detection of antibodies to E. cuniculi in hares from Europe showing that hares could be exposed to E. cuniculi infection, however with a low rate.

Abstract
BACKGROUND Indication of radiotherapy in lymphoma treatment is an important strategic decision requiring comprehensive expertise. It also calls for a better definition of the position of radiotherapy in clinical practice. DESIGN This position paper represents a consensus between hematooncologists and radiation oncologists on the role of RT in treatment of different histological types and stages of malignant lymphomas. The discussion was underway within professional societies of both specializations (Czech Lymphoma Study Group for the hematooncologists and the Society of Radiation Oncology, Biology and Physics for the radiation oncologists). RESULTS The consensus presented here was reached in early 2012 and draws on evidence-based medicine and clinical practice. Besides defining the role of radiotherapy in lymphoma treatment, this paper also gives specific recommendations on total doses of radiotherapy in lymphoma treatment. CONCLUSION These recommendations will supplement 7th edition of "Diagnostic and treatment guidelines in patients with malignant lymphoma" scheduled for publication in 2013.

Abstract
BACKGROUNDS This retrospective study evaluated treatment outcomes in patients undergoing autologous stem cell transplantation (ASCT) for relapsed/refractory Hodgkin lymphoma (HL). PATIENTS AND METHODS Overall, 194 HL patients treated with ASCT between 2000 and 2009 were analyzed. Survival was calculated using Kaplan-Meier method and differences in survival between subgroups with log-rank test. RESULTS Best responses observed after ASCT: 124 complete and 35 partial remissions, 2 patients with stable disease and 33 relapses/progressions. During a median follow-up of 44 months, seventy patients after ASCT progressed/relapsed. Thirty-seven patients received salvage chemotherapy only with or without radiotherapy, 25 underwent allogeneic stem cell transplantation (SCT), 4 the second ASCT and 4 refused treatment. 5-year overall survival after ASCT was 71% and progression-free survival 54%. Median survival of the 70 patients relapsing after ASCT was 16.9 months. Median survival in patients after allogeneic SCT was 31.8 months and 12.4 months in patients treated with other modalities (p = 0.21). Overall mortality was 26.3% (51/194 patients): 13.4% progressions/relapses of HL and 12.9% non-relapse mortality. CONCLUSION Efficacy of ASCT was confirmed in 54% progression-free survivors. Median survival after ASCT failure is relatively short. There is a slightly longer overall survival after allogeneic SCT, although not statistically significant when compared to other approaches.

Abstract
A review of diagnosis of acute promyelocytic leukemia (APL) is presented. There are still many patients with progressive disease with leukocytosis at presentation. These are at greater risk of early death due to bleeding (often intracranial), or, less frequently, due to thrombotic complications. In Czechia, we have, in some instances, noted an unacceptably long time from the first symptoms to diagnosis and to administration of the highly specific differentiation therapy with tretinoin (ATRA) along with anthracycline chemotherapy. This combination is highly efficient--cures are seen in some 70% of patients. Therefore, we present a diagnostic minimum for each and every internist, and even better for every general practician, to get acquainted with. All cases of pancytopenia and consumption coagulopathy should be suspected of APL and referred to a specialized hematologist without any delay. In the following more detailed review of diagnostic measures, much attention is given to APL morphology, which is the first clue leading to diagnosis. The finding of the typical hypergranular FAB M3 morphology and of cells with bundles of Auer rods ("faggot cells"), along with the HLA-DR, CD33+ immunophenotype, is highly (but not absolutely) specific for APL. In cases of the micro-/hypo-granular variant FAB M3v Form, and whenever APL cannot be ruled out with certainty, a test to prove the presence of the PML/RARalpha fusion gene is indicated, using either RT-PCR or, eventually, immunological demonstration of the specific distribution of the PML protein in the cell nucleus. Given that morphology of APL cases, as defined according to WHO criteria (95% of which carry the PML/RARalpha fusion gene), admits extremely divergent morphological pictures ofthe variant forms, we recommend these investigations to be performed in every case of de novo acute myeloid leukemia. A review of the less frequent morphological, as well as genetic variants is given, and the principles of immunophenotypic, cytogenetic and molecular diagnostics are also reviewed.

Abstract
We have retrospectively evaluated a cohort of 144 patients (including 17 pediatric ones) with de novo acute promyelocytic leukemia registered in databases of institutions cooperating within the CELL group (The Czech Leukemia Study Group for Life). The patients were diagnosed according to WHO criteria from 1989 until 2006. The aim was to check how well fared the patients, the majority of whom was not included into clinical trials, in real life. Of 140 evaluable patients, 97 (69.3%) attained complete remission (CR). The projected overall survival (OS) 4 years after diagnosis was 58.9%, and 55.3% at 6 years. In 8 patients (6.0%), no antileukemic therapy at all was given (either they died shortly after admission to the ward or therapy was not feasible due to their clinical status). Of 125 patients with documented commencement of some kind of therapy, 96 (76.8%) achieved CR. Of 102 patients with induction treatment with a combination of anthracycline and tretinoin (ATRA), 84 individuals (82.4%) attained CR (typically, this cohort might have been subjected to clinical trials). This result was better than that of patients treated by chemotherapy only (n = 15; CR 46.7%; P = 0.003) or by ATRA monotherapy (n = 13; CR 62.5%; P = 0.17). Another parameter with a significant impact on attaining CR was the leukocyte (WBC) count at diagnosis: its median values in patients achieving and not achieving CR were 2.1 and 24.0 x 10(9)/l, respectively (P < 0.0001). The WBC counts affected OS as well (P = 0.0001). However, when only patients after attaining CR were evaluated, the initial WBC counts no longer affected OS (P = 0.18). Achieving CR was also influenced by the performance status (PS) 0-1 (P = 0.005), which was in turn closely correlated to WBC counts (P = 0.0006). Additional factors (most likely connected with leukocytosis) influenced attaining CR with borderline statistical significance: e.g. FAB M3v morphology, LDH serum level, fibrinogen level, presence of internal tandem duplication (ITD) of the FLT3 gene (which was strongly associated with leukocytosis and also with the short PML/RARalpha transcript resulting from the bcr3 break in the PML gene). It may be speculated that FLT3-ITD is just one of the possible factors that lead to leukocytosis. The platelet counts at diagnosis had no impact on entering CR. Thus, we have not validated the current PETHEMA risk stratification in distinguishing intertermediate and low risk patients. Our study points to a significant difference of the results obtained in real life and of the results that could be achieved in patients who were fit to enter clinical trials. Among the prognostic factors, the most important one was the WBC count, the PS (which is highly affected by the WBC count), and feasibility of administration of the most potent induction therapy with anthracyclines and ATRA.

Abstract
Resistance to chemotherapy is one of the major obstacles to effective treatment in acute myeloid leukemia (AML). The most extensively studied protein involved in multidrug resistance (MDR) is the transmembrane glycoprotein P (P-gp), the product of the multidrug resistance gene 1 (MDR1). MDR1/P-gp overexpression is frequently observed in hematological malignancies, especially in acute leukemia, and has been reported to correlate with poor prognosis in acute myeloid leukemia (AML). The aim of this study was to evaluate the level of MDR1 gene expression in bone marrow and/or peripheral blood samples in 92 AML patients in relation to their prognosis. The analyzed group was stratified according to presence or absence of prognostically favorable aberrations (PFAs), such as t(15;17) with PML/RARalpha fusion gene, t(8;21) with AML1/ETO fusion gene or inv(16)/ t(16;16) with CBFbeta/MYH11 fusion gene. These prognostically favorable aberrations were detected by RT-PCR and/or standard cytogenetic techniques. MDR1 expression was detected by semiquantitative comparative RT-PCR using software-based evaluation. The levels of MDR1 expression in the bone marrow predicted induction of complete remission in the whole group of analyzed patients (P = 0.032). They were significantly lower in PFA negative patients who achieved complete remission compared to those who failed to achieve complete remission (P = 0.008). In PFA negative patients, MDR1 expression was higher when compared to PFA positive patients (P = 0.055). No such difference was found when analyzing peripheral blood samples. Our experiments showed no impact of MDR1 expression in bone marrow or peripheral blood cells on overall survival (P = 1.000 and P = 0.903 respectively). In summary, the present study shows the prognostic impact of MDR1 expression on induction of complete remission in AML patients. We confirmed that MDR1 overexpression is an unfavorable prognostic factor in AML, which may help to stratify the risk rate of PFA negative patients. In future studies, quantitative detection of MDR1 expression might be a valuable tool to predict prognosis in this patient subset.

Abstract
Morphological examination is the routine first step in the diagnosis of hematological malignancies, including chronic lymphocytic leukemia (CLL). Atypical cell morphology according to the FAB criteria is known to herald disease progression. Several years ago, it was proposed that FAB morphology at diagnosis had a considerable prognostic impact. However, this proposal has not been widely adopted in practice. Thus we questioned the prognostic value of the morphological examination, which was performed retrospectively in 88 patients out of our 110 institutional registry patients (70 males and 40 females, median age 57 yrs) with CLL at diagnosis. We related the results to the more modern prognostic markers. Atypical FAB morphology was shown to correlate with IgVH gene mutation status, trisomy of chromosome 12 and deletion of 17p detected either by conventional G-banding or by fluorescence in situ hybridization (FISH) analysis. The correlation of FAB morphology with CD38 antigen expression or with the histopathological pattern of bone marrow infiltration was not significant. Overall survival (OS) data were available for 84 morphologically examined patients. The patients with atypical morphology (64 patients) had a significantly shorter OS (103 months) than the 20 patients presenting with typical CLL morphology (237 months; p=0.03). Only the mutation status of IgVH genes correlated more closely with OS (p=0.002). Of note, there was no leukemia-related death within "unmutated" cases who had typical FAB morphology (p=0.14), and vice versa, the mutation status had a significant prognostic impact within the morphologically atypical cases (p=0.01). Thus FAB morphology and the mutation status may yield complementary prognostic information. OS was affected both by the presence of cytogenetic aberrations (p=0.03) - most adversely by deletions of 17p and 11q, and by CD38 expression (p=0.003). We conclude that careful examination of peripheral blood smears according to FAB is a simple, cheap and valuable tool in the first-line assessment of prognosis of CLL patients and should not be overlooked even in 3rd millennium when more sophisticated prognostic markers are at hand. This ought to be confirmed in larger prospective studies with multivariate analysis of data.

Abstract
BACKGROUND Despite a considerable effort, the majority of acute myeloid leukaemia (AML) patients do not have a suitable specific molecular marker for monitoring minimal residual disease (MRD). The results of some studies suggest the Wilms tumour gene (WT1) as a possible molecular marker of MRD. METHODS AND RESULTS We measured the expression of WT1 at diagnosis and during treatment of the acute myeloid leukaemia (AML) patients. The expression of WT1 was measured by the quantitative real-time RT-PCR in peripheral leukocytes from 56 AML at diagnosis and 7 patients with AML transformed from myelodysplastic syndromes (MDS). The WT1 expression was significantly elevated (up to 3 orders of magnitude) in peripheral blood samples (PB) of AML patients at diagnosis compared to PB samples of healthy donors (P < 0.0001). The level of WT1 expression depends particularly on FAB AML subtype, with the highest being found in AML patients with subtypes M4, M1, M3 and AML transformed from MDS. Conversely, AML patients with M2 and with the presence of AML1/ET0 at presentation showed a significantly lower expression of the WT1 gene compared to the remaining AML patients at presentation (P = 0,005). Further, sequence samples of 12 AML patients under long-term surveillance were tested for the WT1 expression in parallel with the expression of specific MRD markers--fusion genes: AMLI/ETO, PML/RARalpha and CBFB/MYH11. The levels of WT1 gene expression and the above specific fusion genes significantly correlated. Moreover, 14 patients without the specific MRD marker were tested for the WT1 expression. The results show that haematological relapses were associated with the rise of expression of the specific fusion genes and with the WT1 gene expression. The rise of WT1 expression above the level seen in leucocytes from peripheral blood and/or bone marrow of healthy donors--in four patients under long-term surveillance the "molecular relapse" predicted ongoing haematological relapses as early as 2 months in advance. CONCLUSIONS Our results, in accordance with some of the previously published ones, show that WT1 expression seems to be a suitable marker of minimal residual disease in AML patients.

Abstract
PURPOSE To assess the incidence and prognostic significance of osseous Hodgkin's lymphoma. METHODS AND MATERIALS The authors retrospectively analyzed 85 patients treated at their institutions between 1995-2001. They assessed the incidence of bone involvement, involved localities and basic characteristics of the subgroup (age, gender, stage, histology). All patients were treated according to the protocols of the German Hodgkin Study Group (GHSG). Treatment response, disease free- and overall survival were evaluated with special attention to predictive and prognostic significance of bone involvement. RESULTS From the total of 85 eligible patients 10 cases of bone involvement were recorded of who seven were diagnosed primarily and three at relapse. Most frequently involved were lumbar vertebrae. Diagnosis was based on CT and bone scan, biopsy was performed only in one case. In the evaluated subgroup, there was apparently higher incidence of advanced stage disease, other parameters did not differ from the control group. Of the 10 patients, six achieved complete remission, two uncertain complete remission and two progressed primarily. At present, eight patients are alive in complete remission, one is being treated with salvage chemotherapy and high dose therapy with autologous stem cell transplantation. One patient expired due to progressive disease. Median overall survival is 12 months. CONCLUSION Bone involvement is not an adverse predictive factor for treatment response in Hodgkin's lymphoma. Because of short follow-up period seems preliminary to evaluate its prognostic power for disease free- and overall survival.

Abstract
BACKGROUND Positron emission tomography with fluorodeoxyglucose offers the possibility to differentiate between lymphoma and nonmalignant tissue. The aim of this retrospective study was a comparison between PET and conventional imaging methods before and after therapy--during the follow-up of Hodgkin's lymphoma. METHODS AND RESULTS The group of 94 patients with HL underwent 180 PET examinations. PET was performed in 53 patients during initial staging of lymphoma. 119 PET studies were undertaken after therapy during the follow-up. Eight patients underwent PET examination for suspected relapse or progression of HL. Findings were verified by a follow-up in all patients and by histology in selected cases. PET and conventional imaging methods were positive in 42 of 53 (79%) patients in initial stages. The stage of the disease was changed in 7 patients (13.2%) according to PET. False negative findings were recorded in three cases and false positive in one case. Sensitivity of PET was higher compared to conventional imaging methods (92% vs 87%) in initial staging. PET and conventional imaging methods were identical in 94.9% of cases during the follow-up (77.3% negative and 17.6% positive findings). Sensitivity of PET during the follow-up after therapy was higher compared to conventional imaging methods (99.1% vs 95.7%). PET was positive in all eight cases in relapse/progression of HL and conventional imaging methods were positive in only seven of eight cases. CONCLUSIONS PET is a more sensitive method in initial staging, during follow-up and in suspected progression/relapse of HL than conventional imaging methods and it should be included into routine examination methods of HL.

Abstract
Echocardiography is a sensitive method for detecting wall motion abnormalities, as well as for monitoring cardiotoxicity during treatment with anthracyclines. Using echocardiography, this study investigated possible acute cardiotoxicty associated with primary treatment of Hodgkin's disease according to German Hodgkin's Lymphoma Study Group (GHSG) clinical trial protocols for adults. A group of 88 patients (48 men) was registered in the prospective, randomized clinical trial involving the treatment of Hodgkin's disease using third and fourth generation GHSG protocols. These patients were monitored by echocardiography. The average age was 34 years (range, 18-65; median, 32). The average anthracycline dose was 174 mg/m2 (median 200 mg/m2), and the average mediastinum irradiation dose was 21 Gy (median 30 Gy). Left ventricle end-systolic diameter (ESD) and left ventricle end-diastolic diameter (EDD), as well as fractional shortening (FS) and ejection fraction (EF) (M-mode calculation) were evaluated, as was the presence of pericardial effusion and wall motion abnormalities. The examinations were conducted before and at the end of therapy (up to 2 months). Results show that all evaluated parameters changed from one follow-up examination to the other, but these changes did not reach statistical significance. ESD increased from 30 +/- 4 to 31 +/- 4 mm. EDD increased from 49 +/- 4 to 49 +/- 5 mm. Ejection fraction changed from 69 +/- 7 to 66 +/- 7% and fractional shortening was unchanged (from 38 +/- 7 to 38 +/- 7%). In seven patients (8%), we observed new wall motion abnormalities characterized by hypokinesis without decrease of left ventricular function. Significant changes in the amount of pericardial effusion were not observed. In four patients (5%), there was progression of Hodgkin's disease. In conclusion, treatment according to third and fourth generation clinical trial protocols of the GHSG leads only to minimal wall motion changes, without concomitant reduction of left ventricular function, thus not meeting the criteria, acute cardiotoxicity.

Abstract
Most patients with Hodgkin's disease (especially early stage disease) are successfully treated using modern treatment modalities. Disease relapse usually occurs within the first three years after initial therapy. Late relapses of Hodgkin's disease, occurring after 10 years or even later, are rare (0.6% of cases only). Their biological behaviour is different from that of early relapses, resembling primary disease. The question whether very late relapses represent a second primary disease in patients with a genetic predisposition to Hodgkin's disease rather than a relapse of the original disease remains the subject of much discussion. We report here two cases of very late relapses of Hodgkin's disease, occurring twenty years after initial treatment. Both patients were now treated by intensified chemotherapy, escalated BEACOPP. In one case, this was followed by radiotherapy of the residual tumor (40 Gy). Both patients are in complete remission.

Abstract
Locoregional chemotherapy is one of the possible ways of treatment of inoperable metastatic affection of the liver by colorectal carcinoma. The advantage of regional administration of the cytostatic is the possibility to achieve a higher local concentration of the cytostatic associated with a higher percentage of therapeutic responses. In our department we preferred combined locoregional intraarterial chemotherapy (5-fluorouracil/Mitmycin C/Doxorubicin) combined with systemic intravenous chemotherapy (5-fluorouracil/leukovirin). Locoregional cghemotherapy was administered in the majority as chemotherapy of series 2 or 3 with a very good tolerance. In 2/19 patients we observed marked diminution of liver metastases and subsequent operability and with a duration of complete response for 13 and 18 months. In 7/19 patients a partial therapeutic response was achieved. The total therapeutic response (complete and partial) was 47%. Locoregional chemotherapy attains a higher therapeutic response as compared with systemic chemotherapy and is associated with an acceptable toxicity.

Abstract
UNLABELLED The article present an evaluation (02/1999) of the study of primary treatment of Hodgkin's disease (HD) according to the third generation of the German Hodgkin's Disease Study Group (GHSG), and our experience with this treatment strategy. HD7 study of early stages HD showed better results (fewer relapses) for combined chemo and radiotherapy than for radiotherapy alone (2x ABVD + extended field radiotherapy compared to extended field radiotherapy alone). HD8 study of intermediate stage HD did not show any difference between chemotherapy 2x (COPP + ABVD) combined with radiotherapy extended field, or involved field. Due to the long-term consequences (especially secondary neoplasm), in the current (fourth) generation protocol extended field radiotherapy in early and intermediate stage HD has been replaced by a combination of lesser toxic chemotherapy and involved field radiotherapy. HD9 study of advanced HD. The standard treatment at present of COPP/ABVD (A) was compared with the new chemotherapeutic regimen, BEACOPP baseline (B) and escalated (C). The first evaluation of this study (1996) showed better results in the case of BEACOPP. The latest evaluation showed significantly better results for the escalated version. This is best illustrated by the low percentage of disease progression (C 2%, B 8%, A 12%, p < 0.05). Therefore, DHSG is considered to be the new standard for treatment of advanced stage HD. OUR RESULTS Between 1995-1998, 54 patients with primary HD were treated at the FN Královaké Vinohrady, Prague according to the third generation GHSG protocol. Of these, 5 patients (9%) according to HD7, 14 (26%) according to HD8 and 35 patients (65%) according to HD9. Our results correspond to those of the whole GHSG, but they can not be statistically evaluated because of the small number of patients involved.

Abstract
A 62-year-old woman presented with loss of memory and a mild hemiparesis. Neuroradiology demonstrated a left frontoparietal tumour. Biopsy specimens of this lesion revealed intracerebral Hodgkin's lymphoma, a diagnosis supported by immunohistochemical reactions of the tumour cells for the CD30 antigen. Additional cell cycle studies revealed a high proliferative activity of the tumour cells in association with absence of apoptosis. There was no evidence that overexpression of bcl-2 or Epstein-Barr virus infection was involved in the pathogenesis of this neoplasm. Lymphomas in the lung were detected 3 months later. Following neurosurgical excision, radiotherapy, and chemotherapy, the patient had no evidence of Hodgkin's disease after 13 months of follow-up.

Abstract
In clinical practice doctors are frequently faced with the necessity of rapidly influencing a prolonged prothrombin time (Quick's test) in a patient who will have a surgical operation or invasive examination. After establishment of the cause of the prolonged prothrombin time the doctor has the following possibilities: if a planned operation is involved, anticoagulation treatment can be discontinued or vitamin K administered by the oral route, in urgent conditions virus-inactivated vitamin K concentrate dependent coagulation factors can be administered. Every transfusion is associated with the risk of transmissions of disease (hepatitis, HIV and others). Therefore it is better to use these concentrates rather than fresh frozen plasma-FFP.

Abstract
Anomalies of vertebrobasilar vessels arise as early embryonal developmental deteriorations. The majority of them concerns the position, origin and shape of the vertebral and/or basilar arteries. In three patients, reported here, the aberrations were found occasionally and contributed in no way to the clinical symptomatology. In the first patient, a fenestration of A. basilaris was found with a fork-like division on its periphery. In the second patient we noted a doubled proximal origin of the vertebral artery. One artery arose from A. subclavia sinistra, the second one from the aortic arch. Both joined thereafter the common vertebral stem at the level of C4. In the third patient, A. vertebralis originated from the aortal arch, and, at the level of the thyroid, A. thyreoidea inferior originated from it. Attention is drawn to the practical importance of such variations as a possible source of diagnostic errors during cerebral arteriography.

Abstract
Terguride is an ergoline derivative with mixed agonistic/antagonistic dopaminergic activity. This led to a paradoxical suggestion that it is effective in the treatment of both schizophrenia and parkinsonism. A total of 65 in- or outpatients with parkinsonism mostly of vascular or idiopathic etiology were included in a 4-week, open, multicenter trial. Terguride was administered under an increasing dose schedule which was leveled off according to the clinical response. Mostly because of nausea, vomiting, and lack of improvement 25% of inpatients and 61% of outpatients were removed from the study. The average daily dose at the end of the trial was 4.2 mg, ranging from 1.0 to 5.5 mg. The average Simpson and Angus scale total score and performance in the Spiral Drawing Task improved significantly during the trial by 20% and 38% respectively. The following adverse effects were noted most frequently throughout the study (including those who withdrew): constipation (occurred in 42% of all ratings performed during the trial) drowsiness and nausea (16% each). Adverse circulatory effects were negligible. Psychotic symptoms, including depression, confusion, hallucinations, and paranoid syndrome, each occurred in 1 patient, i.e., at a lower rate than with other dopaminergic drugs. Scotopic electroretinograms in a subsample of 7 patients showed a significant transitory decrease in the B-wave amplitude at the end of the 1st week and a subsequent return to pretreatment values.
