    Full Text Available Fever is the principle sign of infection in neutropenic patient and frequently may be the only evidence of infection. The pattern of fever in neutropenia is non-specific and not pathognomonic of any type of infections or non-infectious process and can be suppressed by the antipyretic effects of drugs such as corticosteroids. Neutropenia, resulting from cytotoxic chemotherapy is the most common risk factor for severe infections in hematological malignancies. The duration of neutropenia also contributes significantly to the risk of serious infections. This risk is significantly greater a lower neutrophil counts, such that 100% patients with ANC < 100 cells/µl lasting 3 weeks or more develop documented infections. The prompt initiation of empirical antibiotics in febrile neutropenia has been the most important advance in the management of the immunocompromised host. The initial empirical antibiotic regimen started at presentation of the febrile episode frequently requires modifications especially in high-risk febrile neutropenia. Neutropenic patients who remain febrile despite 4-7 days of broad spectrum antibacterial therapy are at a high risk of invasive fungal infection. Empirical antifungal therapy with Amphotericin B in persistently febrile neutropenic patients and other high risk patients has shown to reduce the risk of invasive fungal infection by 50-80% and the risk of fungal infection related mortality by 23-45% in 1980′s. The IDSA has recommended that amphotericin B at 0.5-0.7 mg/kg/day be administered till marrow recovery. This approach is limited however by the adverse effects caused by drug infusion (fever, chills, myalgias, nausea, hypotension and bronchospasm. Lipid formulations which improve the therapeutic ratio of the traditional formulation are available. The safety and efficacy of these formulations is well established. These formulations have comparable efficacy and are less nephrotoxic than conventional amphotericin B

    Malignant neoplasms of the lymphoid or myeloid cell lines including lymphoma, leukaemia and myeloma are referred to as haematological malignancies. Complementary and alternative treatment options such as meditation practice or yoga are becoming popular by treating all aspects of the disease including physical and psychological symptoms. However, there is still unclear evidence about meditation's effectiveness, and how its practice affects the lives of haematologically-diseased patients. This review aims to assess the benefits and harms of meditation practice as an additional treatment to standard care for adults with haematological malignancies. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 8, 2015), MEDLINE (1950 to August 2015), databases of ongoing trials, the metaRegister of Controlled Trials (mRCT) (http://www.controlled-trials.com/mrct/), conference proceedings of annual meetings of: the American Society of Hematology; American Society of Clinical Oncology; European Hematology Association; European Congress for Integrative Medicine; and Global Advances in Health and Medicine (2010 to 2015). We included randomised controlled trials (RCTs) using meditation practice for adult patients with haematological malignancies. Two review authors independently extracted data from eligible studies and assessed the risk of bias according to predefined criteria. We evaluated quality of life and depression. The other outcomes of overall survival, anxiety, fatigue, quality of sleep and adverse events could not be evaluated, because they were not assessed in the included trial. We included only one small trial published as an abstract article. The included study investigated the effects of meditation practice on patients newly hospitalised with acute leukaemia. Ninety-one participants enrolled in the study, but only 42 participants remained in the trial throughout the six-month follow-up period and were eligible for analysis. There was no

    BACKGROUND: Overall survival in paediatric cancer has improved significantly over the past 20 years. Treatment strategies have been intensified, and supportive care has made substantial advances. Historically, paediatric oncology patients admitted to an intensive care unit (ICU) have had extremely poor outcomes. METHODS: We conducted a retrospective cohort study over a 3-year period in a single centre to evaluate the outcomes for this particularly vulnerable group of patients admitted to a paediatric ICU. RESULTS: Fifty-five patients were admitted a total of 66 times to the ICU during the study period. The mortality rate of this group was 23% compared with an overall ICU mortality rate of 5%. 11\\/15 patients who died had an underlying haematological malignancy. Twenty-eight percent of children with organism-identified sepsis died. CONCLUSIONS: While mortality rates for paediatric oncology patients admitted to a ICU have improved, they are still substantial. Those with a haematological malignancy or admitted with sepsis are most at risk.

Thirty-five of these were neutropenic patients with haematological malignancy and 247 were patients with a normal or raised total white blood cell...... in the two groups of strains. The haematological patients more often than the non-haematological patients had an unknown focus of infection, recurrent bacteraemia, shorter intervals between recurrences and recurrences caused by identical strains. Despite a well-defined focus, six of eight non......-haematological patients had recurrences with a strain different from the strain isolated in a previous episode. A possible connection between shorter intervals and recurrence with identical strains is discussed. We suggest that strains from recurrent E. coli bacteraemia are sent to a reference laboratory for serotyping...

  8. Clostridium difficile Infections amongst Patients with Haematological Malignancies: A Data Linkage Study.

    Full Text Available Identify risk factors for Clostridium difficile infection (CDI and assess CDI outcomes among Australian patients with a haematological malignancy.A retrospective cohort study involving all patients admitted to hospitals in Western Australia with a haematological malignancy from July 2011 to June 2012. Hospital admission data were linked with all hospital investigated CDI case data. Potential risk factors were assessed by logistic regression. The risk of death within 60 and 90 days of CDI was assessed by Cox Proportional Hazards regression.There were 2085 patients of whom 65 had at least one CDI. Twenty percent of CDI cases were either community-acquired, indeterminate source or had only single-day admissions in the 28 days prior to CDI. Using logistic regression, having acute lymphocytic leukaemia, neutropenia and having had bacterial pneumonia or another bacterial infection were associated with CDI. CDI was associated with an increased risk of death within 60 and 90 days post CDI, but only two deaths had CDI recorded as an antecedent factor. Ribotyping information was available for 33 of the 65 CDIs. There were 19 different ribotypes identified.Neutropenia was strongly associated with CDI. While having CDI is a risk factor for death, in many cases it may not be a direct contributor to death but may reflect patients having higher morbidity. A wide variety of C. difficile ribotypes were found and community-acquired infection may be under-estimated in these patients.

    The spleen functions as a filter of the circulating blood, removing aging or abnormal red blood cells, intraerythrocyte inclusions as well as foreign particals. As the spleen is composed of lymphocytic tissue, circulatory elements and mononuclear phagocytic cells it plays an important role in the nonspecific as well as the specific immune response. Additionally, the spleen serves as a reservoir for circulating blood cells, especially platelet sequestration by the spleen is well do cumented. The spleen produces blood cells during fetal development and in certain haematological disorders such as myelofibrosis. The destruction of red blood cells within the splenic cords releases iron in the circulation, which is recycled and used to manufacture new erythrocytes in the bone marrow. In several non-malignant haematological disorders antibody-coated cells are cleared from the circulation by phagocytic cells of the spleen. This involves erythrocytes in autoimmunhaemolytic anaemias, platelets in immunthrombocytopenia and neutrophils in Felty syndrome. In hereditary spherocytosis the spleen destroys the resulting defective, spherical red cells. In pyruvate kinase deficiency impaired production of adenosine triphosphate leads to destruction of red blood cells in the spleen or in the liver. In sickle cell anaemia the defective erythrocytes cause sludging and thrombosis in small vessels with infarcts for instance in the spleen, which over time can result in autosplenectomy. In thalassaemia major abnormal haemoglobin forms protein precipitates in the red cells with development of a severe hypochromic anaemia with haemolysis and intramedullary inef fective erythropoiesis. Therapeutic splenectomy can be an option in all of these mentioned non-malignant haematological disorders. The rationale and the pathophysiology of its role in thrombotic thrombocytopenic purpura is probably at least well understood. The use of new and effective drugs such as the monoclonal antibody rituximab or

    The platelet refractoriness is a complication of transfusion treatments potentially dramatic in onco-haematology. Chemo-treatment of haematological malignancies or packs of allogeneic bone marrow transplants require iterative platelet transfusion requirements. The discovery of a platelet refractoriness along with its support should be the most reactive as possible but also adapted to the cause. In the case of allo-immunization, it may be expected. The purpose of this presentation is to recall the different etiologies and perform a feedback on the support transfusion platelet of onco-haematology adult patients at Institut Paoli-Calmettes (IPC) in partnership with the EFSAM.

    Pneumocystis jirovecii can cause life-threatening pneumonia following treatment for haematological malignancies or after HSCT. The mortality rate of P. jirovecii pneumonia (PCP) in these patients is 30%-60%, especially after HSCT. The clinical presentation of PCP in haematology differs from that associated with HIV infection, with the disease being acute and more often severe, having a lower fungal burden and being more frequently linked to treatment with corticosteroids. Most cases occur in patients not receiving adequate prophylaxis. The development of new therapies, including targeted treatments and monoclonal antibodies in various haematological diseases, justifies constant vigilance in order to identify new at-risk populations and give prophylaxis accordingly. The fifth and sixth European Conferences on Infections in Leukaemia (ECIL-5 and ECIL-6) aimed to review risk factors for PCP in haematology patients and to establish evidence-based recommendations for PCP diagnosis, prophylaxis and treatment. This article focuses on the magnitude of the problem, the main differences in clinical presentation between haematology patients and other immunocompromised populations, especially HIV-infected patients, and the main risk factors.

  13. KIR Genes and Patterns Given by the A Priori Algorithm: Immunity for Haematological Malignancies

    Directory of Open Access Journals (Sweden)

    J. Gilberto Rodríguez-Escobedo

    2015-01-01

    Full Text Available Killer-cell immunoglobulin-like receptors (KIRs are membrane proteins expressed by cells of innate and adaptive immunity. The KIR system consists of 17 genes and 614 alleles arranged into different haplotypes. KIR genes modulate susceptibility to haematological malignancies, viral infections, and autoimmune diseases. Molecular epidemiology studies rely on traditional statistical methods to identify associations between KIR genes and disease. We have previously described our results by applying support vector machines to identify associations between KIR genes and disease. However, rules specifying which haplotypes are associated with greater susceptibility to malignancies are lacking. Here we present the results of our investigation into the rules governing haematological malignancy susceptibility. We have studied the different haplotypic combinations of 17 KIR genes in 300 healthy individuals and 43 patients with haematological malignancies (25 with leukaemia and 18 with lymphomas. We compare two machine learning algorithms against traditional statistical analysis and show that the “a priori” algorithm is capable of discovering patterns unrevealed by previous algorithms and statistical approaches.

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Objective: To survey the role of protein tyrosine kinases (PTKs) in the pathogenesis of several hematopoietic malignancies. Methods: By reviewing the published laboratory and clinical studies on PTK-related oncoproteins and their causative role in some leukemias and lymphomas. Results: Protein tyrosine kinases are key participants in signal transduction pathways that regulate cellular growth, activation and differentiations. Aberrant PTK activity resulting from gene mutation (often accompanying chromosome translocation) plays an etiologic role in several clonal hematopoietic malignancies. For example, the PTK product of the BCR-ABL fusion gene resulting from the t (9; 22) translocation exhibits several fold higher tyrosine kinase activity than the product of the ABL gene. Evidence suggests that the BCR-ABL oncoprotein alone is sufficient to case chronic myelogenous leukemia (CML) and other Ph positive acute leukemia. PTK over-activity resulting from chromosomal translocations creating TEL-ABL, TEL-JAK2 and TEL-PDGFR( fusion proteins plays an important role in the pathogenesis of other types of leukemia. Another example occurs in anaplastic large cell lymphoma (ALCL). Experimental and clinical evidences indicate that translocations involving ALK gene on chromosome 2p23, most commonly resulting in an NPM-ALK fusion oncogene, result in constitutive activation of ALK and cause ALCL. This group of lymphomas is now named ALK positive lymphoma or ALKoma. Conclusion: Genetic lesions creating aberrant fusion proteins that result in excessive PTK activity are increasingly being recognized as central to the pathogenesis of hemotopoietic malignancies. These chimeric PTK molecules represent attractive disease-specific targets against which new classes therapeutic agents are being developed.

    Haematological malignancies are a diverse group of cancers that affect the blood, bone marrow and lymphatic systems. Laboratory diagnosis of haematological malignancies is dependent on combining several technologies, including morphology, immunophenotyping, cytogenetics and molecular genetics correlated clinical details and classification according to the current WHO guidelines. The concept of the Specialised Integrated Haematological Malignancy Diagnostic Services (SIHMDS) has evolved since the UK National Institute for Health and Care Excellence (NICE) Improving Outcomes Guidance (IOG) in 2003 and subsequently various models of delivery have been established. As part of the 2016 update to the NICE IOG, these models were systematically evaluated and recommendations produced to form the basis for quality standards for future development of SIHMDS. We provide a summary of the systematic review and recommendations. Although the recommendations pertain to the UK National Health Service (NHS), they have relevance to the modern delivery of diagnostic services internationally.

    Invasive mould sinusitis (IMS) is a severe infection in patients with haematological malignancies. Because of a paucity of contemporaneous data about IMS, we sought to evaluate clinical aspects and outcome of IMS in these patients. The records of adult haematological malignancy patients with proven or probable IMS over a 10 year period were reviewed retrospectively. We identified 44 patients with IMS. Mucorales were isolated in 13 (35.1%) patients and Fusarium and Aspergillus were isolated in 9 (24.3%) patients each. Patients with IMS owing to Mucorales were more likely to have a history of diabetes mellitus (P = 0.003) and high-dose corticosteroid use (P = 0.03). Thirty-five (80%) patients received antifungal combinations and 36 (82%) underwent surgical debridement. The 12 week IMS-attributable mortality was 36.4% (16 patients). A relapsed and/or refractory haematological malignancy was an independent risk factor for 6 week IMS-attributable (P = 0.038), 12 week all-cause (P = 0.005) and 12 week IMS-attributable (P = 0.0015) mortality. Neutrophil count <100/µL and lymphocyte count <200/µL were associated with increased 12 week IMS-attributable and 6 week all-cause mortality, respectively (P = 0.044 and 0.013). IMS due to Aspergillus was an independent risk factor for both 12 week all-cause (P = 0.011) and IMS-attributable (P = 0.026) mortality. Initial antifungal therapy with a triazole-containing regimen was associated with decreased 6 week all-cause (P = 0.032) and IMS-attributable (P = 0.038) mortality. Surgery was not an independent factor for improved outcome. Despite combined medical and surgical therapy, IMS had high mortality. Mortality risk factors were relapsed and/or refractory malignancy, cytopenia and Aspergillus infection in this study. © The Author 2015.

    Between April 2000 and May 2005, 350 bacteraemic episodes occurred among patients treated in our haematology unit. Two hundred and twenty-eight of these episodes were caused by Gram-positive pathogens, most commonly coagulase-negative staphylococci and Staphylococcus aureus. One hundred and twenty-two episodes were due to Gram-negative pathogens, with a predominance of Escherichia coli, Acinetobacter baumannii and Pseudomonas aeruginosa. Bacillus bacteraemias constituted 12 of these episodes occurring in 12 patients, and accounted for 3.4% of all bacteraemic episodes. Of the 12 strains evaluated, seven were Bacillus licheniformis, three were Bacillus cereus and two were Bacillus pumilus. Seven episodes presented with bloodstream infection, three with pneumonia, one with severe abdominal pain and deterioration of liver function, and one with a catheter-related bloodstream infection. B. licheniformis was isolated from five patients who had been hospitalized at the same time. This outbreak was related to non-sterile cotton wool used during skin disinfection. B. cereus and B. licheniformis isolates were susceptible to cefepime, carbapenems, aminoglycosides and vancomycin, but B. pumilus isolates were resistant to all antibiotics except for quinolones and vancomycin. Two deaths were observed. In conclusion, Bacillus spp. may cause serious infections, diagnostic and therapeutic dilemmas, and high morbidity and mortality in patients with haematological malignancies. Both B. cereus and B. licheniformis may be among the 'new' Gram-positive pathogens to cause serious infection in patients with neutropenia.

    The primary objective of this study was to determine the volume of distribution (Vd) (L/kg) of intravenous aminoglycosides (AGs) in critically ill haematological malignancy patients. Secondary objectives were to determine the body weight (actual, ideal, adjusted or lean) that yields the most precise estimate of Vd when normalised in L/kg as well as the frequency that current first-dose strategies result in post-distributional peak concentrations (C(peak)) within the target range (tobramycin 16-24 mg/L; amikacin 32-48 mg/L). In total, 58 AG doses were included (tobramycin, n = 34; amikacin, n = 24). Median Vd was 0.38 L/kg normalised per the most precise dose weight, which was actual body weight (ABW). The median dose was 445 mg (5.8 mg/kg ABW) for tobramycin and 1200 mg (13.8 mg/kg ABW) for amikacin. Target C(peak) (tobramycin 20mg/L; amikacin 40 mg/L) was achieved in only 25% of all AG episodes, with 4% exceeding the target and 71% falling below the target. Twenty-four organisms were isolated in the study sample; target C(peak) achievement (tobramycin 20 mg/L; amikacin 40 mg/L) would yield a peak:minimum inhibitory concentration of 10 in 75% and 52% of organisms, respectively. In conclusion, an increased Vd of AGs was identified in this critically ill haematological malignancy patient sample, and current dosing yielded a suboptimal C(peak) in the majority of patients.

    Standard treatment regimens for haematological malignancies include myeloablative chemoradiotherapy and subsequent rescue by stem cell transplantation. However, these treatment regimens have significant associated mortality and morbidity, and disease recurrence remains a problem. One alternative approach is the targeted delivery of radiotherapy to the marrow using a bone-seeking agent labelled with an appropriate radioisotope, with the aim of delivering a potentially ablative radiation dose to marrow while minimising non-haematological toxicity. Pharmacokinetics and radiation dosimetry for a commercial preparation of samarium-153 ethylene diamine tetramethylene phosphonate (EDTMP; Quadramet) were evaluated in 43 tracer (average dose 740 MBq) studies of 42 patients with haematological malignancies. Measurements of 24-h retention were also available following infusion of 18-48 GBq in 15 patients. Quadramet cleared rapidly from the tissue, with a median biological half-life of 1.4 h. Activity taken up by the skeleton was firmly bound, with activity decreasing according to physical half-life at 24 h in 29 of the 43 cases. The percentage activity retained in the skeleton at 24 h with tracer doses was high (62%{+-}13%), although this decreased to approximately 30% with therapy infusions. Because of this decrease in retention, the maximum feasible therapy activity for this formulation of Quadramet is 35 GBq. Median absorbed marrow radiation dose was 0.78 Gy/GBq in tracer studies: the decreased retention at high activities means that this corresponds to a median dose of 12 Gy for 35 GBq administered activity. It is possible to use 24-h retention as a rough guide to marrow dose in individual patients. In tracer studies, median bladder radiation dose was 0.22 Gy/GBq and radiation dose to the liver was very conservatively estimated at 0.2 Gy/GBq. After therapy infusions of up to 50 GBq in 37 patients, non-haematopoietic toxicity was not seen in any patient. In addition

Measurements of 24-h retention were also available following infusion of 18-48 GBq in 15 patients. Quadramet cleared rapidly from the tissue, with a median biological half-life of 1.4 h. Activity taken up by the skeleton was firmly bound, with activity decreasing according to physical half-life at 24 h in 29 of the 43 cases. The percentage activity retained in the skeleton at 24 h with tracer doses was high (62%+/-13%), although this decreased to approximately 30% with therapy infusions. Because of this decrease in retention, the maximum feasible therapy activity for this formulation of Quadramet is 35 GBq. Median absorbed marrow radiation dose was 0.78 Gy/GBq in tracer studies: the decreased retention at high activities means that this corresponds to a median dose of 12 Gy for 35 GBq administered activity. It is possible to use 24-h retention as a rough guide to marrow dose in individual patients. In tracer studies, median bladder radiation dose was 0.22 Gy/GBq and radiation dose to the liver was very conservatively estimated at 0.2 Gy/GBq. After therapy infusions of up to 50 GBq in 37 patients, non-haematopoietic toxicity was not seen in any patient. In addition

    Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is an established treatment option for many malignant and non-malignant disorders. In the past two decades, peripheral blood stem cells replaced bone marrow as stem cell source due to faster engraftment and practicability. Previous meta-analyses analysed patients treated from 1990 to 2002 and demonstrated no impact of the stem cell source on overall survival, but a greater risk for graft-versus-host disease (GvHD) in peripheral blood transplants. As transplant indications and conditioning regimens continue to change, whether the choice of the stem cell source has an impact on transplant outcomes remains to be determined. To assess the effect of bone marrow versus peripheral blood stem cell transplantation in adult patients with haematological malignancies with regard to overall survival, incidence of relapse and non-relapse mortality, disease-free survival, transplant-related mortality, incidence of GvHD and time to engraftment. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 1), MEDLINE (from 1948 to February 2014), trial registries and conference proceedings. The search was conducted in October 2011 and was last updated in February 2014. We did not apply any language restrictions. We included randomised controlled trials (RCTs) comparing bone marrow and peripheral blood allogeneic stem cell transplantation in adults with haematological malignancies. Two review authors screened abstracts and extracted and analysed data independently. We contacted study authors for additional information. We used the standard methodological procedures expected by The Cochrane Collaboration. We included nine RCTs that met the pre-defined selection criteria, involving a total of 1521 participants. Quality of data reporting was heterogeneous among the studies. Overall, the risk of bias in the included studies was low.For the primary outcome overall survival, our

    Few data are available on whether adjusting the dose of posaconazole syrup is effective in patients receiving anti-cancer chemotherapy. The aim of this prospective study was to analyse the impact of increasing the frequency of posaconazole administration on optimal plasma concentrations in adult patients with haematological malignancy. A total of 133 adult patients receiving chemotherapy for acute myeloid leukaemia or myelodysplastic syndrome who received posaconazole syrup 200 mg three times daily for fungal prophylaxis were enrolled in this study. Drug trough levels were measured by liquid chromatography-tandem mass spectrometry. In 20.2% of patients (23/114) the steady-state concentration of posaconazole was suboptimal (posaconazole administration was increased to 200 mg four times daily. On Day 15, the median posaconazole concentration was significantly increased from 368 ng/mL [interquartile range (IQR), 247-403 ng/mL] to 548 ng/mL (IQR, 424-887 ng/mL) (P = 0.0003). The median increase in posaconazole concentration was 251 ng/mL (IQR, 93-517 ng/mL). Among the patients with initially suboptimal levels, 79% achieved the optimal level unless the steady-state level was posaconazole syrup is effective for achieving optimal levels in patients with haematological malignancy undergoing chemotherapy.

    Differences in regulatory actions between Japan, the European Union (EU) and the United States (US) regarding the approval date and primary endpoints of pivotal trials have never been analysed comprehensively. This study aimed to examine such differences in haematological malignancy indications not only in applications for new molecular entity agents but also in supplemental applications for additional indications. A total of 101 haematological malignancy indications were examined for 58 drugs. Only 30 indications were approved by the regulatory agencies of all three regions with 25, 9 and 67 indications being first approved in Japan, the EU and the US, respectively. Regarding the 18 indications approved only in the US, 13 were approved based on results of single-arm trials. The approval of all nine indications approved first in the EU was based on results of comparative trials. The primary endpoints were different between the EU and the US in 4 of 49 indications approved by both regulatory agencies, all of which were approved earlier in the US than in the EU. This analysis shows that the US Food and Drug Administration has taken the most active attitude to acceptance of surrogate endpoints in single-arm trials. Therefore, not only shorter review time but also this attitude may lead to earlier approval in US. © 2016 John Wiley & Sons Ltd.

    For patients with haematological malignancies, information on disease, prognosis, treatment and impact on quality of life is of the utmost importance. To gain insight into the perceived need for information in relation to sociodemographic and clinical parameters, comorbidity, quality of life (QoL) and information satisfaction, we compiled a questionnaire based on existing validated questionnaires. A total of 458 patients diagnosed with a haematological malignancy participated. The perceived need for information was moderate to high (40-70%). Multivariate regression analyses showed that a higher need for information was related to younger age, worse QoL, being member of a patient society and moderate comorbidity. The need for disease and treatment-related information was higher than the need for psychosocial information. A higher need for disease and treatment-related information was associated to being diagnosed with multiple myeloma. A higher need for psychosocial information was related to a lower educational level. The information provision could be improved according to 41% of the patients. Higher satisfaction with provided information was associated with better QoL. Most patients (62%) reported that they wanted to be fully informed about their illness and actively involved in treatment decision-making. The results contribute to improving patient-tailored information provision and shared decision-making in clinical practice. Copyright © 2014 John Wiley & Sons, Ltd.

    The aim of this study was to determine the effect of art therapy on post-traumatic growth in patients with haematological malignancies in a non-randomised trial (n = 36, intervention group; n = 129, control group). Art therapy was administered over a period of 22 weeks in small groups. Post-traumatic growth was measured with the Stress-Related Growth Scale. After controlling for the effect of potential confounders, no difference in post-traumatic growth was observed between the intervention and control groups after 22 weeks. There was no evidence for an effect of weekly group sessions with art therapy on post-traumatic growth in patients with haematological malignancies.

    In parallel to development of individualised antineoplastic treatment, scientific interest in patients' subjective theories of illness (STOI) has emerged in the oncological community. STOI depend decisively on patients' information about their disease. Coping with illness is dependent from the individual situation and context, and it is generally modulated by patients' STOI. The purpose is fivefold: (1) to provide a thorough literature review about coping and about STOI in adult haematological patients, (2) to survey through which indicators the topics were operationalized in studies, (3) to clarify the kind of coherence between these two topics, (4) to explicate the interaction between STOI and other variables, and (5) to verify the clinical relevance of both topics. We searched 19 electronic databanks for English biomedical literature manuscripts (1995-2008) on this subject. Twenty-six studies met our criteria and varied in haematological entity, treatment concept, sample size and methodological design. We conclude that a subjective-individual regulation of patient's mental stability during a cytotoxic chemotherapy is important. Successful coping strategies develop not only based on objective, but also subjective evaluation mechanisms. We deduce consequences for doctor-patient communication and psychosocial care in haematology. The newly developed process model of subjective regulation in cancer patients, in general, views the oncological treatment process as a procedural mental evaluation.

    Full Text Available Several severe complications may be associated with the use of central venous catheters (CVC. We retrospectively evaluated on a large cohort of patients the incidence of CVC-related early and late complications. From 7/99 to 12/2005, 1102 CVC have been implanted at our Institution in 881 patients with haematological malignancies (142,202 total day number of implanted CVC. Early mechanic complications were 79 (7.2% - 0.55/1,000 days/CVC. Thirty-nine episodes of early infective complications (<1 week from CVC implant occurred (3.5% - 0.3/1000 days/CVC: furthermore, 187 episodes of CVC-related sepsis (17% - 1.3/1000 days/CVC were recorded. There were 29 episodes (2.6% of symptomatic CVC-related thrombotic complications, with a median interval from CVC implant of 60 days (range 7 – 395. The rate of CVC withdrawal due to CVC-related complications was 26%. The incidence of CVC-related complications in our series is in the range reported in the literature, notwithstanding cytopenia often coexisting in haematological patients.

    Haematological malignancies (HM) represent over 6% of the total cancer incidence in Europe and affect all ages, ranging between 45% of all cancers in children and 7% in the elderly. Thirty per cent of childhood cancer deaths are due to HM, 8% in the elderly. Their registration presents specific challenges, mainly because HM may transform or progress in the course of the disease into other types of HM. In the context of cancer registration decisions have to be made about classifying subsequent notifications on the same patient as the same tumour (progression), a transformation or a new tumour registration. Allocation of incidence date and method of diagnosis must also be standardised. We developed European Network of Cancer Registries (ENCR) recommendations providing specific advice for cancer registries to use haematology and molecular laboratories as data sources, conserve the original date of incidence in case of change of diagnosis, make provision for recording both the original as well as transformed tumour and to apply precise rules for recording and counting multiple diagnoses. A reference table advising on codes which reflect a potential transformation or a new tumour is included. This work will help to improve comparability of data produced by population-based cancer registries, which are indispensable for aetiological research, health care planning and clinical research, an increasing important area with the application of targeted therapies.

    There is paucity of information from eastern India with regard to observed dominant micro-organisms causing febrile neutropenia (FN) in patients with haematological malignancies. To identify the prevalence of pathogenic microorganisms associated with FN. A total number of 268 episodes of FN were analysed from September'2010 to October'2013. The blood samples were inoculated into brain heart infusion broth, glucose broth, Hicombi dual performance media (Himedia, LQ-12) at 37° C for 168 h and Bactec method was also performed for these samples. Blood agar, chocolate agar, MacConkey's agar and cystine lactose electrolyte deficient agar were used for isolation of the microorganisms. A total number of 78 (29.10 %) episodes revealed positive growths. Gram negative bacilli and Gram positive cocci were isolated in 61.53 and 34.61 % cases respectively. The eight commonest isolates were Pseudomonas aeruginosa (14.10 %), methicillin resistant Staphylococcus aureus (MRSA-12.82 %), Acinetobacter sps (11.53 %), coagulase negative Staphylococcus (10.25 %), Klebsiella pneumoniae (8.97 %), Escherichia coli (8.97 %), ESBL E. coli (6.41 %), methicillin sensitive S. aureus (MSSA-6.41 %). Amongst other less common isolates were Citrobacter kosseri (3.84 %), Citrobacter freundii (2.56 %), Ralstonia paucula (2.56 %), Cedecia neteri (1.28 %), methicillin resistant coagulase negative Staphylococcus (2.56 %). Candida spp. including two cases of Candida non-albicans was isolated in 3.84 % of cases. P. aeruginosa was the commonest pathogenic isolates in FN patients associated with haematological malignancies in this study. Gram negative bacteria were the commonest isolates in FN including significant numbers of rare opportunistic micro-organisms.

    Invasive aspergillosis (IA) is a life-threatening infection in severely immunocompromised haematological malignancy patients. In this study, the efficacy and safety of caspofungin, voriconazole or the combination as primary and salvage therapy in patients with IA were compared. The study included 181 patients with haematological malignancies and IA who received primary or salvage therapy with caspofungin, voriconazole or the combination. In total, 138 patients who received treatment for ≥7 days were analysed; 86 underwent primary antifungal therapy (15 with caspofungin, 38 with voriconazole and 33 with both). Among the salvage therapy patients, 17 received caspofungin, 24 received voriconazole and 35 received both. In the primary therapy group, no difference in therapy response was found, but caspofungin was associated with higher IA mortality rates. A multivariate competing risk analysis of primary antifungal therapy revealed that voriconazole was independently associated with lower IA-associated mortality rates than caspofungin (hazard ratio=0.2, 95% confidence interval 0.06-0.96; P=0.04). In the salvage therapy group, the three treatment groups had similar responses and IA-associated mortality rates. The combination of voriconazole and caspofungin did not result in better outcomes compared with voriconazole alone, as primary or salvage therapy, in haematological malignancy patients. However, voriconazole was associated with a lower Aspergillus-associated mortality rate compared with caspofungin monotherapy.

    The Haematological Malignancy Research Network (HMRN) was established in 2004 to provide robust generalizable data to inform clinical practice and research. It comprises an ongoing population-based cohort of patients newly diagnosed by a single integrated haematopathology laboratory in two adjacent UK Cancer Networks (population 3.6 million). With an emphasis on primary-source data, prognostic factors, sequential treatment/response history, and socio-demographic details are recorded to clinical trial standards. Data on 8131 patients diagnosed over the 4 years 2004-08 are examined here using the latest World Health Organization classification. HMRN captures all diagnoses (adult and paediatric) and the diagnostic age ranged from 4 weeks to 99 years (median 70.4 years). In line with published estimates, first-line clinical trial entry varied widely by disease subtype and age, falling from 59.5% in those aged <15 years to 1.9% in those aged over 75 years - underscoring the need for contextual population-based treatment and response data of the type collected by HMRN. The critical importance of incorporating molecular and prognostic markers into comparative survival analyses is illustrated with reference to diffuse-large B-cell lymphoma, acute myeloid leukaemia and myeloma. With respect to aetiology, several descriptive factors are highlighted and discussed, including the unexplained male predominance evident for most subtypes across all ages.

    Combination of mannan antigen and anti-mannan antibody (Mn/A-Mn) testing has been reported a useful and specific strategy for diagnosis of invasive Candida infections (ICIs). We evaluated Mn/A-Mn as a screening tool in patients with haematological malignancies. This clinical prospective study was performed at the Division of Hematology, Medical University Graz, Austria between July and December 2012. Patients at risk for fungal infection were included into the study and twice weekly screened by Mn/A-Mn testing, yielding 650 samples. Of overall 67 patients 66 had no evidence for ICI. From those, 153/640 serum samples (23.9%) were positive for mannan Ab, and nine (1.4%) for Ag. Most false positive Ab results were observed among 375 samples from patients without haematopoietic stem cell transplantation (34.9% resulted positive). Combined specificity of Mn/A-Mn was 74.8%. Of 10 samples obtained in the single patient with candidemia, five were positive for mannan Ag (from the day of diagnosis up to 40 days after detection of candidemia) and none for Ab. In conclusion, mannan Ab screening yielded a high number of false positive results. While mannan Ag was found to be highly specific and may have potential for diagnostic driven testing, mannan Ab testing cannot be recommended based on our study results. © 2016 Blackwell Verlag GmbH.

Detecting β-d-glucan in serum can contribute to the diagnosis but not the follow-up of PCP ( A-II: ). A negative serum β-d-glucan result can exclude PCP in a patient at risk ( A-II: ), whereas a positive test result may indicate other fungal infections. Genotyping using multilocus sequence markers can be used to investigate suspected outbreaks ( A-II: ). The routine detection of dihydropteroate synthase mutations in cases of treatment failure is not recommended ( B-II: ) since these mutations do not affect response to high-dose co-trimoxazole. The clinical utility of these diagnostic tests for the early management of PCP should be further assessed in prospective, randomized interventional studies.

    Several publications have focused on the cardiotoxicity of specific classes of hematological therapeutic agents such as antracyclines and cyclofosfamide. Cardiotoxicity of cancer chemotherapeutics is a problem for patients of all ages, but it increases with age. Toxicity can also develop months after the last chemotherapy dose, and late reactions can be seen years later when they present as new-onset cardiomyopathy. No data are available about the cardiotoxicity of non-chemotherapy agents currently used as preferred therapy for hematological malignancy in elderly. In this review we have provided a summary of the cardiovascular toxic effects produced by different drugs and therapeutic agents. Early identification of patients who are at risk for cardiotoxicity should be a primary goal for hematologists in the development of personalized antineoplastic therapeutic strategies or interventions. Thus, the discovery of new biomarkers to identify patients at a high risk for the development of these complications is a high priority. Although targeted therapies such as imatinib and anti-CD20 antibody such rituximab are considered less toxic and better tolerated by patients compared with classic chemotherapy drugs, certain cardiological complications can be very serious and as these agents have been in use for a limited period of time.

    Full Text Available Abstract Background Hand-held dynamometry is a portable and inexpensive method to quantify muscle strength. To determine if muscle strength has changed, an examiner must know what part of the difference between a patient's pre-treatment and post-treatment measurements is attributable to real change, and what part is due to measurement error. This study aimed to determine the relative and absolute reliability of intra and inter-observer strength measurements with a hand-held dynamometer (HHD. Methods Two observers performed maximum voluntary peak torque measurements (MVPT for isometric knee extension in 24 patients with haematological malignancies. For each patient, the measurements were carried out on the same day. The main outcome measures were the intraclass correlation coefficient (ICC ± 95%CI, the standard error of measurement (SEM, the smallest detectable difference (SDD, the relative values as % of the grand mean of the SEM and SDD, and the limits of agreement for the intra- and inter-observer '3 repetition average' and the 'highest value of 3 MVPT' knee extension strength measures. Results The intra-observer ICCs were 0.94 for the average of 3 MVPT (95%CI: 0.86–0.97 and 0.86 for the highest value of 3 MVPT (95%CI: 0.71–0.94. The ICCs for the inter-observer measurements were 0.89 for the average of 3 MVPT (95%CI: 0.75–0.95 and 0.77 for the highest value of 3 MVPT (95%CI: 0.54–0.90. The SEMs for the intra-observer measurements were 6.22 Nm (3.98% of the grand mean (GM and 9.83 Nm (5.88% of GM. For the inter-observer measurements, the SEMs were 9.65 Nm (6.65% of GM and 11.41 Nm (6.73% of GM. The SDDs for the generated parameters varied from 17.23 Nm (11.04% of GM to 27.26 Nm (17.09% of GM for intra-observer measurements, and 26.76 Nm (16.77% of GM to 31.62 Nm (18.66% of GM for inter-observer measurements, with similar results for the limits of agreement. Conclusion The results indicate that there is acceptable relative reliability

    INTRODUCTION: Nowadays Enterococcus faecium has become one of the most emerging and challenging nosocomial pathogens. The aim of this study was to determine risk factors in haematology patients who are at risk of an Enterococcus faecium bloodstream infection (BSI) and should be considered for pre-em

    Myeloablative allogeneic haematopoietic stem cell transplantation (allo-HSCT) is a major procedure usually accompanied by multifactorial malnutrition, prompting the recommendation of systematic artificial nutritional support. Parenteral nutrition (PN) is usually administered during allo-HSCT, essentially for practical reasons. Recently published data suggest that enteral nutrition (EN), given as systematic artificial nutrition support, could decrease grade III-IV graft-versus-host disease (GVHD) and infectious events, which are associated with early toxicity after allo-HSCT and then have an impact on early transplant-related mortality (D100 mortality). We report on the NEPHA trial: an open-label, prospective, randomised, multi-centre study on two parallel groups, which has been designed to evaluate the effect of EN compared to PN on early toxicity after an allo-HSCT procedure. Two hundred forty patients treated with allo-HSCT for a haematological malignancy will be randomly assigned to two groups to receive either EN or PN. The primary endpoint will assess the effect of EN on D100 mortality. Secondary endpoints will compare EN and PN with regards to the main haematological, infectious and nutritional outcomes. The impacts of nutritional support should exceed the limits of nutritional status improvement: EN may directly reduce immunological and infectious events, as well as decrease early transplant-related morbidity and mortality. EN and PN need to be prospectively compared in order to assess their impacts and to provide treatment guidelines. (Clinical trials gov number: NCT01955772; registration: July 19th, 2013).

    Fusions of dendritic cells (DCs) and tumour cells have been shown to induce protective immunity to tumour challenge in animal models, and to represent a promising approach to cancer immunotherapy. The broader clinical application of this approach, however, is potentially constrained by the lack of replicative capacity and limited standardisation of fusion cell preparations. We show here that fusion of ex vivo tumour cells isolated from patients with a range of haematological malignancies with the human B-lymphoblastoid cell line (LCL), HMy2, followed by chemical selection of the hybridomas, generated stable, self-replicating human hybrid cell lines that grew continuously in tissue culture, and survived freeze/thawing cycles. The hybrid cell lines expressed HLA class I and class II molecules, and the major T-cell costimulatory molecules, CD80 and CD86. All but two of 14 hybrid cell lines generated expressed tumour-associated antigens that were not expressed by HMy2 cells, and were therefore derived from the parent tumour cells. The hybrid cell lines stimulated allogeneic T-cell proliferative responses and interferon-gamma release in vitro to a considerably greater degree than their respective parent tumour cells. The enhanced T-cell stimulation was inhibited by CTLA4-Ig fusion protein, and by blocking antibodies to MHC class I and class II molecules. Finally, all of five LCL/tumour hybrid cell lines tested induced tumour antigen-specific cytotoxic T-cell responses in vitro in PBL from healthy, HLA-A2+ individuals, as detected by HLA-A2-peptide pentamer staining and cellular cytotoxicity. These data show that stable hybrid cell lines, with enhanced immunostimulatory properties and potential for therapeutic vaccination, can be generated by in vitro fusion and chemical selection of B-LCL and ex vivo haematological tumour cells.

    The 5th European Conference on Infections in Leukaemia (ECIL-5) meeting aimed to establish evidence-based recommendations for the prophylaxis of Pneumocystis jirovecii pneumonia (PCP) in non-HIV-infected patients with an underlying haematological condition, including allogeneic HSCT recipients. Recommendations were based on the grading system of the IDSA. Trimethoprim/sulfamethoxazole given 2-3 times weekly is the drug of choice for the primary prophylaxis of PCP in adults ( A-II: ) and children ( A-I: ) and should be given during the entire period at risk. Recent data indicate that children may benefit equally from a once-weekly regimen ( B-II: ). All other drugs, including pentamidine, atovaquone and dapsone, are considered second-line alternatives when trimethoprim/sulfamethoxazole is poorly tolerated or contraindicated. The main indications of PCP prophylaxis are ALL, allogeneic HSCT, treatment with alemtuzumab, fludarabine/cyclophosphamide/rituximab combinations, >4 weeks of treatment with corticosteroids and well-defined primary immune deficiencies in children. Additional indications are proposed depending on the treatment regimen.

    Accumulating evidence suggests that cancer can be envisioned as a "signaling disease", in which alterations in the cellular genome affect the expression and/or function of oncogenes and tumour suppressor genes. This ultimately disrupts the physiologic transmission of biochemical signals that normally regulate cell growth, differentiation and programmed cell death (apoptosis). From a clinical standpoint, signal transduction inhibition as a therapeutic strategy for human malignancies has recently achieved remarkable success. However, as additional drugs move forward into the clinical arena, intrinsic and acquired resistance to "targeted" agents becomes an issue for their clinical utility. One way to overcome resistance to targeted agents is to identify genetic and epigenetic aberrations underlying sensitivity/resistance, thus enabling the selection of patients that will most likely benefit from a specific therapy. Since resistance often ensues as a result of the concomitant activation of multiple, often overlapping, signaling pathways, another possibility is to interfere with multiple, cross-talking pathways involved in growth and survival control in a rational, mechanism-based, fashion. These concepts may be usefully applied, among others, to agents that target two major signal transduction pathways: the one initiated by epidermal growth factor receptor (EGFR) signaling and the one converging on mitogen-activated protein kinase (MAPK) activation. Here, we review the molecular mechanisms of sensitivity/resistance to EGFR inhibitors, as well as the rationale for combining them with other targeted agents, in an attempt to overcome resistance. In the second part of the paper, we review MAPK-targeted agents, focusing on their therapeutic potential in haematologic malignancies, and examine the prospects for combinations of MAPK inhibitors with cytotoxic agents or other signal transduction-targeted agents to obtain synergistic anti-tumour effects.

    In view of the poor outcomes associated with mucormycosis in patients with haematologic malignancies (HM) and haematopoietic cell transplant recipients, antifungal combinations are frequently used, yet the value of such strategy remains unclear. We reviewed the records of HM patients treated for mucormycosis from 1994 to 2014. The primary outcome was 6-week mortality after treatment initiation. Of the 106 patients identified, 44% received monotherapy and 56% received combination treatment as initial therapy. Six-week mortality was associated with disseminated mucormycosis (p 0.018), active malignancy (p mucormycosis (p mucormycosis was associated with better outcome (OR, 0.06; 95% CI, 0.01-0.6; p 0.019). Initial combination treatment had no impact on mortality, even after propensity score adjustment (OR, 0.8; 95% CI, 0.3-2.4; p 0.69). A weighted mortality risk score was then calculated for each patient based on the factors independently associated with mortality and baseline APACHE II score. In the low-risk group (n = 49), 13% of monotherapy versus 15% of combination therapy patients died within 6 weeks (p >0.99). In the high-risk group (n = 57), 71% of monotherapy versus 61% of combination therapy patients died within 6 weeks (p 0.42). With the current status of mucormycosis diagnosis, there was no difference in mortality in HM patients, whether they received monotherapy or combination treatment as initial therapy. Earlier diagnosis and immune reconstitution are unmet needs to affect outcomes.

    The aim of this study was to predict the probability of central venous catheter-related bloodstream infections (CRBSIs) in patients with haematologic malignancies using a modified version of the Infection Probability Score (mIPS). In order to perform a prospective, mono-centric surveillance of complications in clinical routine due to short-term central venous catheters (CVCs) in consecutive patients receiving chemotherapy from March 2013 to September 2014, IPS was calculated at CVC insertion and removal (mIPSin and mIPSex, respectively). We used the 2012 Infectious Diseases Working Party of the German Society of Haematology and Medical Oncology (AGIHO/DGHO) criteria to define CRBSI. In total, 143 patients (mean 59.5 years, 61.4 % male) with 267 triple-lumen CVCs (4044 CVC days; mean 15.1 days, range 1-60 days) were analysed. CVCs were inserted for therapy of acute leukaemia (53.2 %), multiple myeloma (24.3 %) or lymphoma (11.2 %), and 93.6 % were inserted in the jugular vein. A total of 66 CRBSI cases (24.7 %) were documented (12 definite/13 probable/41 possible). The incidence was 16.3/1000 CVC days (2.9/3.1/10.1 per 1000 CVC days for definite/probable/possible CRBSI, respectively). In CRBSI cases, the mIPSex was higher as compared to cases without CRBSI (13.1 vs. 7.1; p < 0.001). The best mIPSex cutoff for CRBSI prediction was 8 points (area under the curve (AUC) = 0.77; sensitivity = 84.9 %, specificity = 60.7 %, negative predictive value = 92.4 %). For patients with an mIPSex ≥8, the risk for a CRBSI was high (odds ratio [OR] = 5.9; p < 0.001) and even increased if, additionally, CVC had been in use for about 10 days (OR = 9.8; p < 0.001). In case other causes of infection are excluded, a mIPSex ≥8 and duration of CVC use of about 10 days predict a very high risk of CRBSI. Patients with a mIPSex <8 have a low risk of CRBSI of 8 %.

    Full Text Available In the last decades, the global epidemiological impact of invasive candidiasis (IC in patients with hematologic malignancies (HM and in hematopoietic stem cell transplant (HSCT recipients has decreased and the incidence of invasive aspergillosis  exceeded that of Candida infections. The use of prevention strategies, first of all antifungal prophylaxis with triazoles,  contributed to the reduction of IC in these populations as demonstrated by several  epidemiological studies. However, relatively little is known about the current epidemiological patterns of IC in HM and HSCT populations, because recent epidemiological data almost exclusively derive from retrospective experiences and few prospective data are available. Several prospective, controlled studies in the prophylaxis of invasive fungal diseases have been conducted in both the HM and HSCT setting. On the contrary, most of the prospective controlled trials that demonstrated the efficacy of the antifungal drugs echinocandins and voriconazole in the treatment of candidemia and invasive candidiasis mainly involved  patients with underlying conditions other than HM or  HSCT.  For these reasons, international guidelines provided specific indications for the prophylaxis strategies in HM and HSCT patients, whereas the  recommendations on therapy of documented Candida infections are based on the results observed in the general population and should be considered with caution.

    Between 30 and 50% of febrile neutropenic episodes are accounted for by infection. C-reactive protein (CRP) is a nonspecific parameter for infection and inflammation but might be employed as a trigger for diagnosis. The aim of the study was to evaluate whether {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT can be used to detect inflammatory foci in neutropenic patients with elevated CRP and whether it helps to direct treatment. Twenty-eight consecutive patients with neutropenia as a result of intensive chemotherapy for haematological malignancies or myeloablative therapy for haematopoietic stem cell transplantation were prospectively included. {sup 18}F-FDG PET/CT was added to the regular diagnostic workup once the CRP level rose above 50 mg/l. Pathological FDG uptake was found in 26 of 28 cases despite peripheral neutrophil counts less than 0.1 x 10{sup -9}/l in 26 patients: in the digestive tract in 18 cases, around the tract of the central venous catheter (CVC) in 9 and in the lungs in 7 cases. FDG uptake in the CVC tract was associated with coagulase-negative staphylococcal bacteraemia (p < 0.001) and deep venous thrombosis (p = 0.002). The number of patients having Streptococcus mitis bacteraemia appeared to be higher in patients with grade 3 oesophageal FDG uptake (p = 0.08). Pulmonary FDG uptake was associated with the presence of invasive fungal disease (p = 0.04). {sup 18}F-FDG PET/CT scanning during chemotherapy-induced febrile neutropenia and increased CRP is able to detect localized foci of infection and inflammation despite the absence of circulating neutrophils. Besides its potential role in detecting CVC-related infection during febrile neutropenia, the high negative predictive value of {sup 18}F-FDG PET/CT is important for avoiding unnecessary diagnostic tests and therapy.

    Roentgen treatment for painful benign conditions in the locomotor system as arthrosis and spondylosis was in Sweden very common up to the beginning of the 1960s. The mode of treatment differed from the British ankylosing spondylitis series as smaller parts of the red bone marrow were exposed and smaller doses were applied. A cohort of 20024 such patients treated 1950-1964 at two hospitals in northern Sweden was analysed with regard to the risk of haematological malignancies. Average factors for conversion of prescribed skin doses to mean absorbed red bone marrow doses were estimated on random samples of the different treatment sites and then applied on the cohort in its whole. The standard incidence ratio (SIR) for leukaemia was 1.18 (95% CI: 0.98-1.42) and the standard mortality ratio (SMR) 1.25 (0.99-1.45). In the highest dose group (mean absorbed red bone marrow dose > 0.5 Gy) the corresponding values were 1.40 (1.00-1.92) and 1.50 (1.08-2.04). In the mortality analysis also a slightly increased myeloma risk was noted with SMR = 1.20 (0.99-1.56). Extension of the cohort and nested case-control studies are under progress. (orig.).

    Although there is evidence that liposomal amphotericin B (AmBisome) is non-inferior to amphotericin B (AmB) in terms of in vivo efficacy, in vitro data regarding the activity of AmBisome against clinical isolates of Aspergillus are rare. In this study, the susceptibilities to AmB and AmBisome of 103 Aspergillus complex isolates (48 Aspergillus flavus, 33 Aspergillus fumigatus, 13 Aspergillus terreus and 9 Aspergillus niger) recovered from haematological patients with invasive infection were compared. Minimum inhibitory concentrations (MICs) were determined by the broth microdilution (BMD) method according to the Clinical and Laboratory Standards Institute (CLSI), whilst AmB susceptibility was also determined by Etest. Using a susceptible/resistant MIC cut-off of 1mg/L, all A. fumigatus and A. niger complexes isolates were susceptible to both AmB and AmBisome. In contrast, 38.5% and 30.8% of the A. terreus complex isolates were resistant to AmB and AmBisome, respectively, with good agreement between BMD and Etest methods. With respect to A. flavus complex isolates, 43.7% and 16.7% were resistant by the BMD method to AmBisome and AmB, respectively. For isolates with discrepant results, AmB MICs obtained by Etest were higher than those obtained for AmB by the BMD method and they were closer to those obtained for AmBisome by BMD. Aspergillus flavus AmB MICs ranged from 0.5 mg/L to 2 mg/L by the BMD method and from 1 mg/L to >16 mg/L by the Etest method, and AmBisome MICs ranged from 0.06 mg/L to >16 mg/L by the BMD method. Etest appears to be superior to the CLSI BMD method using AmB in detecting AmB resistance of Aspergillus spp., although the CLSI BMD method might be a suitable procedure if AmBisome is used as the test drug.

Among 56 episodes of positive-blood cultures for B. cereus, 21 were considered significant. Median age was 54 years (range 23–82 years. Ten patients (48% had a haematologic malignancy; all were neutropenic at the time of B. cereus bacteraemia. Nonhaematologic patients were either intravenous drug users (n=3, 14%, polytraumatized (n=3, 14% or had multiple chronic comorbidities (n=5, 24%. Most episodes were hospital acquired (15, 71%. Sources of bacteraemia were intravascular catheter (n=11, 52%, digestive tract (n=6, 29%, drug injection (n=3, 14% and wound (n=1, 5%. Adequate antibiotic therapy was provided to 18 patients (86% during a median of 17 days (range 2–253 days. The intravascular catheter was removed in eight cases (42%. Three haematologic patients had a complicated course with neurologic complications (meningoencephalitis and cerebral abscesses. Complications appeared to be associated with catheter infection (100% of complicated cases vs. 29% of noncomplicated cases. In conclusion, B. cereus bacteraemia can have a complicated course in a subset of patients, mainly those with haematologic malignancy. Catheter infection may be associated with a worse outcome with frequent neurologic complications.

    Plasmapheresis also known as a therapeutic plasma exchange (TPE) is a procedure of plasma removal with it's ineligible plasma's component. Usually it is a supportive measure used simultaneously with the treatment, but in a few diseases, e.g. in trombotictrombocytopenic purpura (TTP), it is a first-choice treatment. During the plasmapheresis plasma is mostly replaced by 20% solution of albumin or combination of 20% solution of albumin and 0.9% solution of NaCl, however in some diseases fresh frozen plasma (FFP) is used. Plasmaphereses have found a wide application in different branches of medicine: hematology, neurology, nephrology, reumatology. Plasmapheresis is an invasive procedure, but when performed by qualified staff it is rather safe and serious complications are very rare.The most common complications of plasmapheresis are mild, usually caused by electrolyte disturbances (hypokalemia, hypokalcemia) or anticoagulation. More serious complication can be associated with FFP transfusion, extracorporeal circulation or presence of intravenous catheter. The latter one is usually necessary to perform the plasmapheresis. In haematology the most common indication for plasmapheresis is the supportive treatment of multiple myeloma. The procedure is performed in patients with high protein levels endangered with hyperviscosity syndrome. Less frequent indications to plasmapheresis in haematology are: Waldenström's macroblobulynaemia, idiopathic thrombocytopenic purpura (ITP), pure red cell aplasia (PRCA), polyneuropaties connected with haematological disorders. Supportive treatment of haemofagocytic syndrome (HLH--hemophagocytic lymphohistiocytosis) is one of the new indications. Plasmaphereses are used in treatment of about 150 different diseases and more and more new needs for this method are identified.

    2012-02-01

    Hypercalcaemia is a common metabolic complication of malignant disease often requiring emergency intervention. Although it is more frequently associated with solid tumours, malignancy-associated hypercalcaemia (MAH) is seen in a significant number of patients with blood diseases. Its association with myeloma and adult T-cell leukaemia\\/lymphoma is well recognized but the incidence of hypercalcaemia in other haematological neoplasms, affecting adults and children, is less clearly defined. Haematologists need to be familiar with the clinical manifestations of, the differential diagnosis to be considered and the most effective management strategies that are currently available for MAH. The key components of management of MAH include aggressive rehydration, specific therapy to inhibit bone resorption and, crucially, treatment of the underlying malignancy. Bisphosphonates have revolutionized the management of MAH over the last 20 years, however the elucidation of molecular pathways implicated in MAH is facilitating the development of more targeted approaches to treatment.

    Full Text Available BACKGROUND Neonates are uniquely susceptible to overwhelming bacterial infections. It is very essential to diagnose the sepsis in early phase and it is also important to rule out sepsis to prevent irrational use of antibiotics. Though blood culture is considered as gold standard, it is time consuming with limitation in preterm and has high false negative rates. For the same reason, several rapid haematological tests are done as part of sepsis screen for early diagnosis of neonatal sepsis. OBJECTIVE The study was done to establish the role of haematological parameters like Total Leucocyte Count (TLC, Absolute Neutrophil Count (ANC, Immature to Total Neutrophil ratio (I/T ratio, Platelet count, C – Reactive Protein (CRP, Micro-Erythrocyte Sedimentation Rate (m-ESR, either alone or in combination as reliable indicators of septicaemia in clinically suspected neonates. METHODS A prospective study of 100 neonates clinically suspected as having sepsis, who were admitted to NICU, Navodaya Medical College, Hospital and Research Centre, Raichur were included. The above haematological parameters were evaluated and statistically analysed. RESULTS Among 100 neonates, only 42 cases were positive for blood culture and were considered true positives. Haematological parameters like TLC, I/T ratio, CRP showed high sensitivity, specificity, positive predictive value and negative predictive value as individually or in combination. ANC and micro-ESR showed low sensitivity but high specificity. Results were promising when tests were done in combination using haematological scoring system. CONCLUSION Irrespective of blood culture-positivity, evaluation of haematological parameters aid in early diagnosis and provide a rational basis for therapy and management of neonatal sepsis.

    Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely. Glucocorticoids are used as first-line therapy in patients with SLE with AIHA, but there is no conclusive evidence to guide second-line therapy. Rituximab is promising in refractory and non-responding AIHA. TTP is not recognised as a criteria for classification of SLE, but there is a considerable overlap between the presenting features of TTP and SLE, and a few patients with SLE have concurrent

    Objective To investigate the predictive power of infection probability score (IPS) for clostridium difficile-associated diarrhea (CDAD) in patients with haematological malignancies. Methods From January 2009 to January 2011,95 patients with haematological malignancies in the hospital were included. The receiver operating characteristic(ROC) curve was used to assess the predictive power of IPS for CDAD. Results The mean score of the participants' IPS was 11. 8 ± 6. 5. The incidence rate of CDAD was 10. 5%. Compared with the patients' score without CDAD, the score of patients with CDAD was significantly higher(14. 2 ± 7. 9 vs 10. 3 ± 5. 2,t=1. 782,P = 0. 031). The best cutoff value of IPS for the prediction of CDAD was 16 with a sensitivity of 75. 5%, a specificity of 80. 3%, AUC of 0. 76, a positive predictive value of 66. 1% and a negative predictive value of 89. 7%. Conclusion IPS is regarded as a valued screen tool for CDAD in patients with haematological malignancies. It is important to carry out predictive nursing and improve nursing quality.%目的 探讨感染可能性评分(infection probability score,IPS)预测血液肿瘤患者发生难辨梭状芽孢杆菌相关性腹泻(clostridium difficile associated diarrhea,CDAD)的可行性.方法 采用便利抽样法选择2009年1月至2011年1月入住温州医学院附属第二医院血液内科的恶性肿瘤患者95例为研究对象,利用受试者工作特征(receiver operating characteristic,ROC)曲线评价IPS诊断CDAD的能力.结果 IPS评分平均为(11.8±6.5)分,CDAD的发生率为10.5%.发生CDAD患者的IPS评分[(14.2±7.9)分]明显高于未发生CDAD者[(10.3±5.2)分],差异有统计学意义(t=1.782,P=0.031).IPS评分系统诊断CDAD的最佳预测值为16,灵敏度为75.5%,特异度为80.3%,曲线下面积为0.76,阳性预测值为66.1%,阴性预测值为89.7%.结论 IPS可作为一个筛选CDAD的有价值的工具,对于开展预见性护理、提高护理质量具有重要意义.

    Full Text Available BACKGROUND Indications for transfusion include symptomatic anaemia, haemolytic anaemia, haematological malignancy, acute sickle cell crisis, and acute blood loss of more than 30 percent of blood volume, sepsis, etc. Fresh frozen plasma infusion can be used for reversal of anticoagulant effects. Platelet transfusion is indicated to prevent haemorrhage in patients with thrombocytopenia or platelet function defects. Cryoprecipitate is used in cases of hyperfibrinogenaemia, which most often occurs in the setting of massive haemorrhage or consumptive coagulopathy, factor VIII deficiency and Von Willebrand disease as an alternate to specific component therapy. Transfusion-related infections are less common than non-infectious complications. All non-infectious complications of transfusion are classified as non-infectious serious hazards of transfusion. Acute complications occur within minutes to 24 hours of the transfusion, whereas delayed complications may develop days, months or even years later. Blood transfusion can be a lifesaving procedure, but it has risks, including infectious and non-infectious complications. There is debate in the medical literature concerning the appropriate use of blood and blood products. Clinical trials investigating their use suggest that waiting to transfuse at lower haemoglobin levels is beneficial. This study will consider the indications for transfusion of blood and blood products, and will discuss common non-infectious complications associated with transfusion. Requirement of blood and blood component transfusions in children admitted in a tertiary care hospital and its related complications. OBJECTIVE To evaluate the pattern of transfusion requirement in children admitted in a tertiary care hospital and the frequency of transfusion related complications. METHODS Children of various age groups presenting with clinical profile like symptomatic anaemia, haemolytic anaemia, haematological malignancy, acute sickle cell

    Antimicrobial Stewardship Programs (ASPs) have appeared as very useful tools in order to improve the use of antimicrobial agents. The objective of this study is to assess the impact of an ASP on haematological patients hospitalized in an Intensive Care Unit (ICU). A quasi-experimental pre-post intervention study, which included haematological patients admitted to an ICU and assessed by the ASP program during 3 years. The impact of the program on patient evolution was assessed by comparison between the previous period and the intervention period in terms of mortality, mean stay, number of re-hospitalizations, and duration of mechanical ventilation for intubated patients. The ASP team assessed 324 antimicrobial agents in 169 patients; they recommended 121 modifications, including 55 treatment discontinuations. Compared with the pre-intervention period, there were no significant differences in the variables assessed. No variation was observed in colonization by multi-resistant bacteria. The implementation of an APS on critical haematological patients will lead to a relevant number of treatment modifications, without any impact on the clinical evolution of patients.

    Non-communicable diseases are increasing worldwide due to rapidly changing lifestyles and socio-economic status. It is contributing significantly to the global burden of diseases. To determine the pattern of non-communicable diseases in children admitted into the Paediatrics ward in a tertiary health centre in Enugu. A review of admissions into the Paediatrics ward of the University of Nigeria Teaching Hospital Enugu, between January 1999 and December 2008 was done using the registry of admission and discharge. The age range of patients admitted during the period was 2 months to 18 years (mean 5.27 ± 5.42 years). There were 1173 (59.6%) males and 796 (40.4%) females. Disorders of the haematological system accounted for 514 (23.3%) of the non-communicable diseases among the admissions, malignancies accounted for 424 (19.2%) among the admissions, whereas the renal, central nervous, and cardiovascular systems were involved in 282 (12.8%), 274 (12.4%), and 241 (10.9%) patients, respectively. There were 274 (12.4%) deaths and 1667 (75.5%) discharges while 38 (1.7%) were discharged against medical advice. Data on 221(10.2%) of the patients were reported missing. Malignancies contributed to 75 (27.3%) of the deaths, haematological disorders accounted for 44 (16%) whereas renal disorders and nutritional disorders contributed to 43 (15.7%) and 41 (15%) of the deaths, respectively. Non-communicable diseases affect children in our environment and contribute to morbidity and mortality in children. Strategies to prevent these diseases should be encouraged in order to avert the challenges of double burden of the diseases in children.

    2011-03-01

    Full Text Available Zygomycoses are rare emerging diseases with a high fatality rate.  The most important risk factors include neutropenia or functional neutropenia, diabetic ketoacidosis, iron overload, major trauma, prolonged use of corticosteroids, illicit intravenous drug use, neonatal prematurity, malnourishment, and pre-exposure to antifungal agents with no activity against zygomycetes, such as voriconazole and caspofungin. A high index of suspicion is crucial for the diagnosis, as prompt and appropriate management can considerably reduce morbidity and mortality. Suspicion index can be increased through recognition of the differential patterns of clinical presentation. In the non- haematological immunocompromised patients, zygomycosis can manifest in various clinical forms, depending on the underlying condition: mostly as rhino-orbital or rhino-cerebral in diabetes patients, pulmonary infection in patients with malignancy or solid organ transplantation, disseminated infection in iron overloaded or deferoxamine treated patients, cerebral - with no sinus involvement - in ID users, gastrointestinal in premature infants or malnourishment, and cutaneous after direct inoculation in immunocompetent individuals with trauma or burns. Treating a patient’s underlying medical condition and reducing immunosuppression are essential to therapy. Rapid correction of metabolic abnormalities is mandatory in cases such as uncontrolled diabetes and corticosteroids or other immunosuppressive drugs should be discontinued where feasible. AmphotericinB or its newer and less toxic lipid formulations are the drugs of choice regarding antifungal chemotherapy, while extensive surgical debridemend is essential to reduce infected and necrotic tissue. A high number of cases could be prevented through measures including diabetes control programmes and proper pre- and post-surgical hygiene.

    Many patients with haematological malignancies experience barriers in clinical communication. Reaching effective communication is of great importance as it has been linked to a range of improved patient outcomes such as satisfaction, compliance to treatment, perceived quality of life and physical and mental health. To get a better understanding how communication in haematological consultations can be improved, the current study focussed on patients' preferences and perceived performances regarding the communicative behaviour of their health care professional. Secondly, the mediation of an online communication tool for patients was analysed. Within a controlled pre- post-test design, 78 datasets of clinical consultations could be analysed. Patients considered both affective and instrumental communication aspects important. The affective communication behaviour of the health care professional met the patients' pre-visit preferences well. In the information exchange, more variability and discrepancies were found. Overall, the online intervention did not seem to influence the patients' perceived communication performance of their health care professional much. To further improve the communication during clinical consultations, health care professionals should inquire about patients' expectations, especially during the exchange of information and advices. At the same time, patients should be supported to express their preferences at the start of the consultation. The study was registered in the Netherlands Trial Register, number 3779.

    Typhoid fever can involve various organs, leading to a wide range of presentations: from uncomplicated to complicated typhoid fever. The haematological changes are common in typhoid fever and include anaemia, leucopaenia, thrombocytopaenia and bleeding diathesis. This study was undertaken in order to determine the clinical and haematological presentation of typhoid fever in children. In this study, records of children and adolescents with typhoid fever aged under or equal to 16 years, admitted to Yuzuncu Yil University Hospital between 2010 and 2014, were analysed retrospectively. The cases (56%) were admitted to our hospital in July and October. Major symptoms of patients were abdominal pain (24%), arthralgia (21%) and fever (11%). In our study, decreased mean platelet volume (31%), eosinopaenia 20%), abnormal platelet count (19%), anaemia (16%), leucocytosis (16%) and eosinophilia (12%) were the most common haematological findings in the children. Typhoid fever is predominant in children at school age with a slight male predominance. Decreased mean platelet volume and abdominal pain might be useful as early diagnostic clues.

    ADMIT (ALMA Data Mining Toolkit) is a toolkit for the creation and analysis of new science products from ALMA data. ADMIT is an ALMA Development Project written purely in Python. While specifically targeted for ALMA science and production use after the ALMA pipeline, it is designed to be generally applicable to radio-astronomical data. ADMIT quickly provides users with a detailed overview of their science products: line identifications, line 'cutout' cubes, moment maps, emission type analysis (e.g., feature detection), etc. Users can download the small ADMIT pipeline product (<20MB), analyze the results, then fine-tune and re-run the ADMIT pipeline (or any part thereof) on their own machines and interactively inspect the results. ADMIT will have both a GUI and command line interface available for this purpose. By analyzing multiple data cubes simultaneously, data mining between many astronomical sources and line transitions will be possible. Users will also be able to enhance the capabilities of ADMIT by creating customized ADMIT tasks satisfying any special processing needs. Future implementations of ADMIT may include EVLA and other instruments.

    The role of interleukin-6 (IL-6) in tumorigenesis and in particular in haematological malignancies is crucial. On the basis of the favourable results obtained in the subset of multicentric Castleman disease (MCD), Siltuximab, a chimeric, human-murine, immunoglobulin (Ig) Gk monoclonal antibody directed against human IL-6 has been evaluated in haematological malignancies such as multiple myeloma, myelodisplastic syndromes and non Hodgkin lymphomas. Areas covered: This review discusses available data related to the role of IL-6 as a therapeutic target, the characteristics of Siltuximab in term pharmacokinetics and pharmacodynamics properties and a detailed analysis of the studies involving haematological malignancies with a peculiar focus on non Hodgkin lymphoma. Expert opinion: The results obtained with Siltuximab in haematological malignancies and in particular with non Hodgkin lymphoma are inferior to those obtained in MCD. The complex interaction between malignant clones, inflammatory background and host response could justify this difference. New interesting areas of study are the role of Siltuximab in early phase of multiple myeloma (smoldering multiple myeloma) and if there may be a possible future application in the treatment of Waldenström macroglobulinemia.

In the non- haematological immunocompromised patients, zygomycosis can manifest in various clinical forms, depending on the underlying condition: mostly as rhino-orbital or rhino-cerebral in diabetes patients, pulmonary infection in patients with malignancy or solid organ transplantation, disseminated infection in iron overloaded or deferoxamine

    Full Text Available Three cases of rheumatoid arthritis (RA, presenting with refractory anaemia, thrombocytopenia and peripheral lymphocytosis respectively, were observed. In all the cases haematological manifestations were unrelated to disease activity or drug toxicity. These patients were detected to have pure red cell aplasia (PRCA (normocytic normochromic anaemia, reticulocytopenia and absence of erythroid precursors in the bone marrow, immune thrombocytopenia (IT (absence of splenomegaly and presence of increased megakaryocytes in the bone marrow and multiple myeloma (MM (lytic lesions on skull, paraproteinaemia and bone marrow plasmacytosis respectively. PRCA and IT responded to glucocorticoids. Association with these three haematological alterations has rarely been reported. Our report highlights the need to regularly monitor blood counts in patients with RA.

    Full Text Available Some haematological alterations due to active cases of tuberculosis caused by Mycobacterium tuberculosis were investigated in Enugu Urban of South East, Nigeria. The results revealed thrombocythaemia, leucocytosis and elevated Erythrocyte sedimentation rates (p and lt;0.05. There was oligocythaemia, as well as reduced haematocrit and haemoglobin concentrations (p and lt;0.05. The significant oligocythaemia, anaemia, reduced packed cell volume found in active TB positive persons are all attributed to invasion of haematopoietic organs by any of the Mycobacteria tuberculosis complex (MTBC namely: M tuberculosis, M. bovis, M africanum, M. canetti, M. microti, and M. leprae, which reduced substantially the rate of erythropoiesis. The invasion of lymphoid organs such as lymph nodes, thymus and tonsils by MTBC stimulated the synthesis of leucocytes leading to leucocytosis (p and lt;0.05. This could be an inflammatory response which prepared the victim to defend itself against any of the MTBC that invaded the lungs and might even invade other extrapulmonary organs. Thrombocythaemia in active TB is attributed to haemoptysis, since the latter occurs whenever there is a wound or a threat to tissue injury or damage. When these changes in haematological parameters are used in combination with other tests, microscopic and clinical methods, TB diagnosis and treatment could be well improved.

    The aim of this work is to list the different conditioning used these last twenty years, in pediatrics for malignant hemopathy, then to evaluate the efficiency and the toxicity of these different conditioning by calculating and comparing the T.R.M. ( treatment related mortality), the D.F.S. (disease free survival) and the global survival. This work suggests a behavior liking homogeneous and adapted. In this study none of the 2 conditionings (T.A.M. or T.B.i.-E.D.X.) seems superior than we consider all the population of the malignant pediatric hemopathy or the only L.A.L.. The T.A.M. is more toxic but limits relapses. The global survival is similar. The adoption of homogeneous practices at the French level even European is a desirable objective. (N.C.)

  19. Gaucher disease: haematological presentations and complications.

    Science.gov (United States)

    Thomas, Alison S; Mehta, Atul; Hughes, Derralynn A

    2014-05-01

    Gaucher disease (GD) is an autosomal recessive lysosomal storage disease, caused by deficiency of the enzyme glucocerebrosidase, required for the degradation of glycosphingolipids. Clinical manifestations include hepatosplenomegaly, thrombocytopenia, bone disease and a bleeding diathesis, frequently resulting in presentation to haematologists. Historically managed by splenectomy, transfusions and orthopaedic surgery, the development of specific therapy in the form of intravenous enzyme replacement therapy in the 1990s has resulted in dramatic improvements in haematological and visceral disease. Recognition of complications, including multiple myeloma and Parkinson disease, has challenged the traditional macrophage-centric view of the pathophysiology of this disorder. The pathways by which enzyme deficiency results in the clinical manifestations of this disorder are poorly understood; altered inflammatory cytokine profiles, bioactive sphingolipid derivatives and alterations in the bone marrow microenvironment have been implicated. Further elucidating these pathways will serve to advance our understanding not only of GD, but of associated disorders.

    This study was conducted to evaluate the frequency and pattern of haematological abnormalities (HA) in SLE patients at the time of diagnosis and last follow-up, and their relationship with organ involvement. This retrospective study included patients who were diagnosed and treated for SLE from 1982 to 2008 at King Khalid University hospital, Riyadh. Demographic and haematological parameters at diagnosis and the last follow-up, disease manifestations, organ involvement and clinical hematological complications were recorded. Association of HA with organ involvement was explored by multivariate analysis. A total of 624 patients (90.7% females, mean age 34.3±11.9 years) were studied. HA were present in 516 (82.7 %) patients at the time of diagnosis. Anemia was the most frequent HA in 63.0% patients followed by lymphopenia in 40.3%, leukopenia in 30.0%, thrombocytopenia in 10.9% and autoimmune hemolytic anemia (AIHA) in 4.6% patients. Deep vein thrombosis and pulmonary embolism were diagnosed in 7.4% and 2.6% patients respectively. After a mean follow-up of 9.3±5.3 years, 329/491 (67%) patients still had some HA present. Anemia remained the most common abnormality (51.7% patients) followed by lymphopenia in 33.1%, and thrombocytopenia in 4.8% patients. Leucopenia was associated with oral ulcers (p=0.021) and alopecia (p=0.031), anemia with renal disease (p=0.017), AIHA with neurological involvement (p=0.003), elevated IgG with malar rash (p=0.027), and low C3 with serositis (p=0.026). HA are very common at the time of diagnosis and during follow-up in SLE, and some of these abnormalities are associated with organ damage. This information may help in better management planning of SLE patients.

  1. Charged gravastars admitting conformal motion

    Usmani, A A; Ray, Saibal; Nandi, K K; Kuhfittig, Peter K F; Rakib, Sk A; Hasan, Z

    2010-01-01

    We propose a new model of a {\\it gravastar} admitting conformal motion. While retaining the framework of the Mazur-Mottola model, the gravastar is assumed to be internally charged, with an exterior defined by a Reissner-Nordstr{\\"o}m rather than a Schwarzschild line element. The solutions obtained involve (i) the interior region, (ii) the shell, and (iii) the exterior region of the sphere. Of these three cases the first case is of primary interest since the total gravitational mass vanishes for vanishing charge and turns the total gravitational mass into an {\\it electromagnetic mass} under certain conditions. This suggests that the interior de Sitter vacuum of a charged gravastar is essentially an electromagnetic mass model that must generate the gravitational mass. We have also analyzed various other aspects such as the stress energy tensor in the thin shell and the entropy of the system.

    The recent 58th Annual American Society of Haematology (ASH) meeting held in San Diego shed light on the usual mixture of groundbreaking basic and translational science and the recent practice-changing clinical trials. Recurrent themes this year were the use of recent next-generation sequencing (NGS) techniques to perfect prognostic stratification and disease monitoring. Newer prospects on the role of metabolism in normal and malignant haemopoiesis and mature data on long-awaited trials on immunotherapy and CAR-T cells in lymphoid neoplasms were also discussed.

    Severe forms of acute respiratory distress syndrome in patients with haematological diseases expose clinicians to specific medical and ethical considerations. We prospectively followed 143 patients with haematological malignancies, and whose lungs were mechanically ventilated for more than 24 h, over a 5-y period. We sought to identify prognostic factors of long-term outcome, and in particular to evaluate the impact of the severity of acute respiratory distress syndrome in these patients. A secondary objective was to identify the early (first 48 h from ICU admission) predictive factors for acute respiratory distress syndrome severity. An evolutive haematological disease (HR 1.71; 95% CI 1.13-2.58), moderate to severe acute respiratory distress syndrome (HR 1.81; 95% CI 1.13-2.69) and need for renal replacement therapy (HR 2.24; 95% CI 1.52-3.31) were associated with long-term mortality. Resolution of neutropaenia during ICU stay (HR 0.63; 95% CI 0.42-0.94) and early microbiological documentation (HR 0.62; 95% CI 0.42-0.91) were associated with survival. The extent of pulmonary infiltration observed on the first chest X-ray and the diagnosis of invasive fungal infection were the most relevant early predictive factors of the severity of acute respiratory distress syndrome. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

    Full Text Available Aim: The present investigation screened eighteen clinical cases of canine enteritis for haematological and biochemical analyses. Materials and Methods: Eighteen dogs suffering from enteritis were selected and detailed clinical manifestations were noted. Hematological and biochemical parameters were estimated by using various kits. Blood was also collected from twelve healthy dogs for establishing control values and data obtained were subjected to statistical analysis. Results: The affected dogs showed anorexia, diarrhoea, depression, varying degree of dehydration and tachycardia. There were significant changes in packed cell volume, neutrophils, lymphocytes and mean corpuscular haemoglobin concentration. Biochemical investigation revealed significant decrease in plasma glucose, total plasma protein, albumin and albumin:globulin ratio (A:G ratio. The level of potassium and chloride was markedly decreased. Significant increase in alanine aminotransferase (ALT and blood urea nitrogen (BUN was observed. Conclusion: Packed Cell Volume (PCV and Total Erythrocyte Count (TEC remained almost similar between healthy dogs and dogs affected with diarrhoea. Mean Total Leukocyte Count (TLC value was significantly higher as compared to the control group. Hypoglycemia, hypoproteinemia, hypokalemia, hypochloremia and increase in blood urea nitrogen was observed in dogs suffering from enteritis. [Vet World 2013; 6(7.000: 380-383

    2010-07-01

    Pleural malignancies, primary or metastatic, portend a grim prognosis. In addition to the serious oncologic implications of a pleural malignancy, these tumors can be highly symptomatic. A malignant pleural effusion can cause dyspnea, secondary to lung compression, or even tension physiology from a hydrothorax under pressure. The need to palliate these effusions is a seemingly straightforward clinical scenario, but with nuances that can result in disastrous complications for the patient if not attended to appropriately. Solid pleural malignancies can cause great pain from chest wall invasion or can cause a myriad of morbid symptoms because of the invasion of thoracic structures, such as the heart, lungs, or esophagus. This article reviews pleural malignancies, the purely palliative treatments, and the treatments that are performed with definitive (curative) intent.

    The initiation of systemic antimicrobial treatment of Pneumocystis jirovecii pneumonia (PCP) is triggered by clinical signs and symptoms, typical radiological and occasionally laboratory findings in patients at risk of this infection. Diagnostic proof by bronchoalveolar lavage should not delay...... and secondary anti-PCP prophylaxis is indicated in all patients thereafter. In patients with critical respiratory failure, non-invasive ventilation is not significantly superior to intubation and mechanical ventilation. The administration of glucocorticoids must be decided on a case-by-case basis....... the start of treatment. Most patients with haematological malignancies present with a severe PCP; therefore, antimicrobial therapy should be started intravenously. High-dose trimethoprim/sulfamethoxazole is the treatment of choice. In patients with documented intolerance to this regimen, the preferred...

    2014-01-01

    The 55th annual ASH meeting was held in pleasant New Orleans and was the largest in its history, with 22,495 participants coming from 113 nations. A 'bench-to-bedside and back' attitude characterises haematology probably more than any other discipline in medicine and, as usual, this was reflected in the extremely wide breadth of the topics covered, including the last results from clinical trials and cutting-edge advancements in basic science. This year, the balance was arguably skewed: few truly clinical practice-changing results were presented. On the other hand, a great number of basic and translational studies significantly increased our understanding of the biology of numerous malignancies and heralded the coming of age of disruptive technologies. Namely, above all, next generation sequencing and T cell engineering-based cell therapy.

    Malignant hyperthermia susceptibility remains the commonest cause of death owing to general anaesthesia. This is despite the availability of presymptomatic testing, admittedly by a highly invasive method, and a recognised treatment for implementation immediately a patient shows signs of developing a crisis. Recently the finding of linkage to markers from chromosome 19q13.1-13.2 and the identification of mutations in a candidate gene held out hope of genetic diagnosis being available. However,...

    Haematology research in India is relatively recent in origin. However the pioneers in the field not only did exemplary work when compared to advanced western countries, they also made it a point to develop centres of excellence and human resources for future of haematology work in this country. In this brief overview an effort has been made to give a taste of quality and expanse of haematology research in this country. This review does not claim to have described every bit of haematology research in this country. Our pioneers worked under extremely difficult and trying circumstances on a subject which was limited to funding available from Indian Council of Medical Research. Now the times have changed, several funding agencies in the country are able to provide substantial fund for research. Modern state of the art basic research institutions are tying up with medical colleges for good quality research and the seeds which our pioneers had planted have grown into a mighty tree. It would not be an exaggeration to say we are on the threshold of the golden era of haematology research in this country.

  12. Haematological reference intervals in a multiethnic population.

    Directory of Open Access Journals (Sweden)

    Angeli Ambayya

    Full Text Available INTRODUCTION: Similar to other populations, full blood count reference (FBC intervals in Malaysia are generally derived from non-Malaysian subjects. However, numerous studies have shown significant differences between and within populations supporting the need for population specific intervals. METHODS: Two thousand seven hundred twenty five apparently healthy adults comprising all ages, both genders and three principal races were recruited through voluntary participation. FBC was performed on two analysers, Sysmex XE-5000 and Unicel DxH 800, in addition to blood smears and haemoglobin analysis. Serum ferritin, soluble transferrin receptor and C-reactive protein assays were performed in selected subjects. All parameters of qualified subjects were tested for normality followed by determination of reference intervals, measures of central tendency and dispersion along with point estimates for each subgroup. RESULTS: Complete data was available in 2440 subjects of whom 56% (907 women and 469 men were included in reference interval calculation. Compared to other populations there were significant differences for haemoglobin, red blood cell count, platelet count and haematocrit in Malaysians. There were differences between men and women, and between younger and older men; unlike in other populations, haemoglobin was similar in younger and older women. However ethnicity and smoking had little impact. 70% of anemia in premenopausal women, 24% in postmenopausal women and 20% of males is attributable to iron deficiency. There was excellent correlation between Sysmex XE-5000 and Unicel DxH 800. CONCLUSION: Our data confirms the importance of population specific haematological parameters and supports the need for local guidelines rather than adoption of generalised reference intervals and cut-offs.

    Whether secondary thrombocytosis is a distinguishing clinical biomarker of various diseases, and whether it is an independent predictor of short-term outcome of admitted medical patients is unknown and has never been examined. A cohort of all 138 patients with secondary thrombocytosis (platelets count ≥ 5 x 105/μL) admitted to the department of medicine during the last 2 years was analyzed. Epidemiological and clinical data, and the final diagnosis and outcome were recorded and compared with a cohort of 684 consecutive admitted patients without thrombocytosis. Thrombocytosis was not a non-specific marker of inflammation, because uncomplicated infections and most admission causes were not associated with thrombocytosis, except for inflammatory rheumatic diseases (6% versus 1%), along with anemia (9.4% versus 2.5%) and tumor comorbidity (25% versus 14%). In contrast, thrombocytosis was a distinguishing biomarker for severe pyogenic infections, especially empyema (5% vs. 0%), any abscesses (14% versus 3%), and soft tissue infections (7% versus 3%). Moreover, the thrombocytosis group had significantly more admission days, infections (45% versus 33%), sepsis (21% versus 6%), in-hospital major complications (15% versus 3%) and mortality (19% versus 5%). Finally, thrombocytosis was found to be an independent predictor of mortality, in a multivariate regression analysis. Thrombocytosis is not a simple marker of inflammation. Its presence warrants thorough investigation for the presence of severe underlying disease, mostly complicated pyogenic infections, inflammatory rheumatic diseases and malignancy. Moreover, thrombocytosis is a marker for major complications and is an independent predictor of mortality in admitted medical patients.

    Fall blood counts on 56 clinically normal cranes of nine different species have provided reference values for the interpretation of haematological changes in 13 cranes presenting with abnormal clinical signs. Hypochromic anaemia, heterophilia and lymphocytosis were found in birds with probable Mycobacterium avium infection and heterophilia and lymphocytosis in birds with bumblefoot, arthritis, nephrosis and cardiac myopathy. In several of the cases with heterophilia and lymphocytosis the fibrinogen level was also raised. A senile bird with thickened heart valves showed macrocytosis. The potential diagnostic value of clinical haematology in cranes is discussed.

  19. Blood composition of the reindeer. I. Haematology

    1981-05-01

    Full Text Available The semi-domestic reindeer is a ruminant which exhibits a highly advanced adaptation to the marked seasonality of the northern environment. Since the reindeer has an economic importance and previous information about its blood composition is scanty in respect to age, season, calving and nutrition, the haematology of 578 reindeer were studied. The blood samples were taken from the jugular vein mainly in connection with the marking of calves during summer and at reindeer round-ups in autumn and winter at 10 reindeer rearing subunits in Northern Finland in various seasons in 1973-79. The red blood cell count (8xl012/l, haemoglobin (108 g/1, packed cell volume (35%, white blood cell count (6x109/l and serum iron (26 micromol/1 were low in newborn calves and reached their adult levels in autumn at the age of 5 months (average 11 x 1012/1, 182 g/1, 51%, 9x109/l, 44 micromol/1, respectively. The total serum bilirubin was relatively stable and vitamin B12 high in the first days after birth. The stable serum bilirubin indicates a relatively small breakdown of foetal erythrocytes. E-MCV of adult females was about 49 fl and the diameter of round erythrocytes about 5.5 microm and their thickness about 1.5 microm. No sickling was observed. The red cell osmotic fragility had a initial and final haemolysis points of 0.71 and 0.37% NaCl solution. The relative proportions of neutrophil, eosinophil and basophil granulocytes and agranular lymphocytes and monocytes were 52, 5, 2, 42 and 2 %, respectively. The calving of the reindeer occurs without visible haemorrhage. The body weight, red blood cell count, haemoglobin, packed cell volume and serum iron of pregnant hinds dropped, however, during the early lactation period, and a relative anaemia developed is partly due to iron deficiency and, perhaps, also breakdown of foetal erythrocytes. The means of body weight (range 50-70 kg, red blood cell count (8-11 x 1012/l, haemoglobin (118-185 g/1, packed cell volume (42

    Full Text Available Catatonia is a syndrome characterized by mutism, immobility, negativism, stereotypy, mannerisms, echophenomena, perseveration and passive obedience. The underlying causes can be psychiatric or may be associated with general medical status or neurological diseases. Additionally catatonia has two subtypes as malignant and nonmalignant catatonia. Main symptoms of malignant catatonia are hyperthermia and autonomic symptoms such as tachycardia, tachypnea and hyperhidrosis. It is important to make the diagnosis as early as possible for an appropriate medical treatment. Clinicians should be aware of the fatal outcome of the disease.

    Full Text Available Malignant hyperthermia is a rare metabolic crisis triggered by volatile anesthetics and/or succinylcholine. It is important to remember that hyperthermia is not always present and may even present late in the course. Early recognition of the most common signs and symptoms is critical to diagnosis and treatment. Malignant hyperthermia was associated with a high mortality rate, but this has decreased with the use of dantrolene.  Although this is frequently reported in the anesthesia and surgical literature, it is important that critical care units that use succinylcholine as part of their intubation sequence be prepared to identify and treat this serious syndrome.

    Full Text Available The aim of this review is to discuss current knowledge about pathophysiology and clinical, therapeutic and prophylactic approaches for malignant glaucoma. This type of glaucoma can occur after different surgical procedures. It can also occur in aphakic, phakic and pseudophakic eyes and develop spontaneously in individuals with no ocular surgical history, or associated with topical miotics. Currently, the ultrasound biomicroscopy has provided many interesting and useful findings for diagnosis and monitoring the treatment of malignant glaucoma. It occurs more often in short eyes in which pre operative measurements of the anterior chamber depth and axial length are extremely important for its prophylaxis and diagnosis.

    Full Text Available BACKGROUND The bone marrow examination is an essential investigation for the diagnosis of disorders of the blood and bone marrow. This simple and relatively safe procedure is important, particularly in resource poor centres since access to adjuvant diagnostic techniques are often lacking or absent. MATERIALS AND METHODS 189 patients of all age groups were studied for haematological and non-haematological disorders by bone marrow aspiration in the Department of Pathology, MGM Medical College during the period of 2014 to 2016. RESULTS Majority of the patients who had bone marrow aspiration were aged 0-15 years. The male-to-female ratio was 1:1.03. Most (97% of the marrow aspirate examined had definitive pathologic features, while 14 (7% were normal marrow elements. Out of 189 cases of bone marrow aspiration, acute leukaemia was the most common haematological disease diagnosed using this procedure. Acute lymphoblastic leukaemia was more common than acute myeloid leukaemia. Aplastic anaemia was seen in 16% cases. Megaloblastic anaemia occurred more commonly than other anaemias. Megaloblastic anaemia was seen in 13 cases (7% and microcytic anaemia was seen in 5 cases (3%. There were 10 cases (5% of Idiopathic Thrombocypenic Purpura. Myelodysplastic syndrome and multiple myeloma was seen in 7% and 2% cases respectively. Storage disorder was seen in 3 cases (2%, out of this 02 cases were Gaucher’s disease and one case was Niemann-Pick’s disease. CONCLUSION Bone marrow examination is an important step to arrive at the confirmatory diagnosis of many haematological disorders. This procedure remains a veritable tool in the diagnosis and management of a wide range of haematological diseases, especially in a resource poor centre.

    Invasive mould infections (IMI) are a persistent problem with high morbidity and mortality rates among patients receiving chemotherapy for hematological malignancies and hematopoietic stem cell transplant recipients. Management of IMI in this setting has become increasingly complex with the advent of new antifungal agents and diagnostic tests, which have resulted in different therapeutic strategies (prophylactic, empirical, pre-emptive, and directed). A proper assessment of the individual risk for IMI appears to be critical in order to use the best prophylactic and therapeutic approach and increase the survival rates. Among the available antifungal drugs, the most frequently used in the hematologic patient are fluconazole, mould-active azoles (itraconazole, posaconazole and voriconazole), candins (anidulafungin, caspofungin and micafungin), and lipid formulations of amphotericin B. Specific recommendations for their use, and criteria for selecting the antifungal agents are discussed in this paper. Copyright © 2014. Published by Elsevier Espana.

    2016-01-01

    Objective Well-established cancer registries that routinely link to death registrations can estimate prevalence directly by counting patients alive at a particular point in time (observed prevalence). Such direct methods can only provide prevalence for the years over which the registry has been operational. Time-defined estimates, including 5- and 10-year prevalence, may however underestimate the total cancer burden, and compared with other cancers, there is a lack of accurate information on ...

    Full Text Available Abstract Background Genetic as well as epigenetic alterations are a hallmark of both epithelial and haematological malignancies. High throughput screens are required to identify epigenetic markers that can be useful for diagnostic and prognostic purposes across malignancies. Results Here we report for the first time the use of the MIRA assay (methylated CpG island recovery assay in combination with genome-wide CpG island arrays to identify epigenetic molecular markers in childhood acute lymphoblastic leukemia (ALL on a genome-wide scale. We identified 30 genes demonstrating methylation frequencies of ≥25% in childhood ALL, nine genes showed significantly different methylation frequencies in B vs T-ALL. For majority of the genes expression could be restored in methylated leukemia lines after treatment with 5-azaDC. Forty-four percent of the genes represent targets of the polycomb complex. In chronic myeloid leukemia (CML two of the genes, (TFAP2A and EBF2, demonstrated increased methylation in blast crisis compared to chronic phase (P ATG16L2 was associated with poorer prognosis in terms of molecular response to Imatinib treatment. Lastly we demonstrated that ten of these genes were also frequently methylated in common epithelial cancers. Conclusion In summary we have identified a large number of genes showing frequent methylation in childhood ALL, methylation status of two of these genes is associated with advanced disease in CML and methylation status of another gene is associated with prognosis. In addition a subset of these genes may act as epigenetic markers across hematological malignancies as well as common epithelial cancers.

  12. Children's Motives for Admitting to Prosocial Behavior.

    2016-01-01

    There has been extensive research on children's moral evaluation of lying in prosocial situations. Current knowledge regarding the concept of lying has been derived from studies showing that cultural differences exist, whereby non-Western children tend to rate lie telling more positively than Western children do. These findings suggest that there are different views about whether children should publicize their prosocial behaviors and that children have universal motives when they admit to engaging in prosocial behavior. A gender difference has also been found in relation to prosocial behavior. However, previous studies did not investigate in detail children's motives for admission or non-admission to prosocial behavior, and if there is a gender difference. Therefore, this study examined the diversity in and development of motives for admitting or not admitting to engaging in prosocial behavior, with the aim of clarifying these behaviors as a function of children's grade level in school, and how such motives differ with age and gender. Questionnaires from 1345 elementary and junior high school students in Japan were analyzed. Results showed that children's communication tendency with regard to prosocial behavior reports peaked in the fourth grade of elementary school and gradually decreased thereafter. From the third grade of elementary school onwards, children reported that they refrained from admitting prosocial behaviors. Younger children more likely cited honesty as a crucial motive for admitting to prosocial behaviors. Girls were more likely to endorse honesty as a motive than boys were. Moreover, among younger children, girls feared others' negative evaluation and wanted to comply with modesty norms when not admitting. Further research is needed to examine the developmental process for motives behind prosocial behaviors.

    Pulmonary mucormycosis (PM) is a life-threatening opportunistic mycosis with a variable clinical evolution and few prognostic markers for outcome assessment. Several clinical risk factors for poor outcome present at the diagnosis of PM were analyzed in 75 consecutive hematology patients from 2000-2012. Significant variables (P 22 was associated with 8-fold high rates of mortality (P < 0.0001) within 28 days of diagnosis and median survival of 7 days versus ≥28 days in patients with risk scores ≤22. We found that APACHE II score, severe lymphocytopenia and high LDH levels at the time of PM diagnosis were independent markers for rapid disease progression and death.

    Full Text Available Aim: The aim of the study was to find out alteration in physiological and haematological parameters in bitches affected with pyometra. Materials and methods: Physiological and haematological parameters were studied in twenty eight bitches affected with pyometra. Results: Evaluation of physiological parameters revealed that rectal temperature and respiration rate were increased in the bitches affected with pyometra where as heart rate did not reveal any significant change. In haematological parameters, haemoglobin, packed cell volume (PCV, total erythrocyte count (TEC and lymphocyte count were decreased in the bitches affected with pyometra. The total leucocyte count (TLC, neutrophil count and monocyte count were increased in pyometra. Erythrocytic indices like mean corpuscular volume (MCV, mean corpuscular haemoglobin (MCH and mean corpuscular haemoglobin concentration (MCHC did not show any significant changes in the bitches. Conclusion: Normocytic and normochromic anaemia, leucocytosis, a predominant absolute neutrophilia, lymphopenia and monocytosis were the most common findings in all the bitches affected with pyometra.

    Neuroleptic malignant syndrome (NMS) is a rare idiosyncratic reaction associated with the use of neuroleptics that has an incidence of 0.02 to 3% among patients taking these drugs. This is a very serious complication with a mortality rate that reaches 10-20%. It is therefore very important to have high clinical suspicion and use appropriate criteria to objectify this clinical picture early, stopping the medication causing the picture and to avoid the subsequent complications as much as possible that would be responsible for both its mortality and sequels. We present that case of an 81-year old woman who was admitted to the Psychiatric Hospitalization Unit (PHU) for a depressive episode with psychotic symptoms who developed a neuroleptic malignant syndrome (NMS) when Haloperidol was introduced. After its suspension and subsequent clinical recovery, antipsychotic treatment with Risperidone was reintroduced and she suffered a recurrence of NMS. Finally, significant improvement was achieved with several sessions of electroshock therapy (EST).

    2015-09-01

    ADMIT (ALMA Data Mining ToolkiT), a toolkit for the creation of new science products from ALMA data, is being developed as an ALMA Development Project. It is written in Python and, while specifically targeted for a uniform analysis of the ALMA science products that come out of the ALMA pipeline, it is designed to be generally applicable to (radio) astronomical data. It first provides users with a detailed view of their science products created by ADMIT inside the ALMA pipeline: line identifications, line ‘cutout' cubes, moment maps, emission type analysis (e.g., feature detection). Using descriptor vectors the ALMA data archive is enriched with useful information to make archive data mining possible. Users can also opt to download the (small) ADMIT pipeline product, then fine-tune and re-run the pipeline and inspect their hopefully improved data. By running many projects in a parallel fashion, data mining between many astronomical sources and line transitions will also be possible. Future implementations of ADMIT may include EVLA and other instruments.

    The aim of this study was to further elucidate the activity of the hypothalamo-pituitary-adrenal (HPA) axis in patients with malignancy and to correlate this with the size of the adrenal glands. Fourteen patients with a variety of malignancies were studied prior to receiving cytotoxic chemotherapy. During routine staging computerized tomographic (CT) scans, the size of the body, medial and lateral limbs of the adrenal glands were measured and compared with those of a normal group of patients studied previously. Measurements of 09:00 h serum cortisol and plasma adrenocorticotropic hormone (ACTH) levels were made before and after the administration of dexamethasone (0.5 mg 6-hourly for 48 h) in addition to the peak cortisol response to i.v corticotropin releasing hormone (CRH). Overall, patients with malignancy had significantly larger adrenal glands than patients without malignancy; those with non-haematological malignancies had larger glands than patients with haematological malignancies. Following dexamethasone to suppress circulating cortisol levels, nine patients (64%) demonstrated abnormal resistance with cortisol levels > 50 nmol l(-1): mean value 294 nmol l(-1) (range 67-1147). Those patients who failed to suppress after dexamethasone had significantly larger adrenal glands than those that did suppress and tended to have non-haematological malignancies. ACTH levels were undetectable or low in three patients in whom it was measured and who did not suppress with dexamethasone. Following CRH, the cortisol levels were highest (823 and 853 nmol l(-1)) in two of these patients. Malignancy is associated with diffuse enlargement of the adrenal glands and resistance to dexamethasone-induced suppression of the HPA axis, which is not due to ectopic ACTH secretion. This disturbance of the normal control of the HPA axis is unexplained and its functional significance remains uncertain.

  20. Malignancy in scleroderma patients from south west England: a population-based cohort study.

    2010-01-08

    The pathophysiological relationship between scleroderma and malignancy remains poorly understood. Although some previous studies have demonstrated an increased malignancy risk in patients with scleroderma, others have been inconclusive. We aimed to determine if patients with scleroderma had an increased risk of malignancy compared to an age- and sex-matched local South West England population, and if there were any important differences between scleroderma patients with and without malignancy. Methods of this study are as follows. Notes were obtained on all local scleroderma patients (n = 68) locally, and those diagnosed with malignancy verified by contacting each patient\\'s general practitioner. Expected malignancy figures were obtained from age- and sex-stratified regional prevalence data provided by the South West Cancer Intelligence Service registry. Among the patients, 22.1% with scleroderma were identified with concurrent malignancy. Affected sites were of the breast (n = 5), haematological system (n = 5), skin (n = 4), and unknown primary (n = 1). Overall, malignancy risk was found to be increased in scleroderma (RR = 3.15, 95% CI 1.77-5.20, p = 0.01). In particular, this risk was the highest for haematological malignancies (RR = 18.5, 95% CI 6-43, p = 0.03), especially for non-Hodgkin\\'s lymphoma (RR = 25.8, 95% CI 5-75, p = 0.10). The majority of patients (86.7%) developed malignancy after the onset of scleroderma (mean = 6.9 years). Age of >70 and patients with limited scleroderma were significant risk factors for a patient with scleroderma to have a concurrent malignancy; however, no increased risk was found in patients with any particular pattern of organ involvement, cytotoxic usage or serology. To conclude, in this small patient cohort, we have found that scleroderma is associated with an increased risk of malignancy. This risk is statistically significant in patients with limited scleroderma. Patients who are elderly and those with limited disease

    We address the problem of finding static and spherically symmetric anisotropic compact stars in general relativity that admit conformal motions. The study is framed in the language of f( R) gravity theory in order to expose opportunity for further study in the more general theory. Exact solutions of compact stars are found under the assumption that spherically symmetric spacetimes admit conformal motion with anisotropic matter distribution in nature. In this work, two cases have been studied for the existence of such solutions: first, we consider the model given by f(R)=R and then f(R)=aR+b . Finally, specific characteristics and physical properties have been explored analytically along with graphical representations for conformally symmetric compact stars in f( R) gravity.

    2010-06-01

    Haematological parameters, such as erythrocyte and leucocyte count, erythrocyte indices and thrombocyte number vis-a-vis coagulation of blood has been considered bioindicators of toxicosis in fish following exposure to organochlorine, organophosphate, carbamate and pyrethroid insecticides. This review deals with the effects of insecticides on the morphology of red blood cells, total erythrocyte count, haemoglobin content, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, erythrocyte sedimentation rate, total and differential leucocyte counts, thrombocyte count and clotting time in the peripheral blood of a number of teleosts. The review also takes stock of knowledge of the subject and explores prospects of additional research in the related area.

    The haematological indices in 26 workers who came in contact with radioactive and toxic wastes dumped in Koko village, Nigeria, were compared with those in 26 workers at a port 1 km away from the dump site and with those in 26 controls derived from Port Harcourt, which is about 200 km from the dump site. The site workers showed a macrocytic anaemia and a leucopenia that affected the minority components rather than the neutrophils or lymphocytes. Radiation injury was the likely cause of the findings in the site workers.

    Full Text Available Introduction. Flow cytometry markers have been proposed as useful predictors for the occurrence of posttraumatic inflammatory complications. However, currently the need for a dedicated laboratory and the labour-intensive analytical procedures make these markers less suitable for clinical practice. We tested an approach to overcome these limitations. Material and Methods. Neutrophils of healthy donors were incubated with antibodies commonly used in trauma research: CD11b (MAC-1, L-selectin (CD62L, FcγRIII (CD16, and FcγRII (CD32 in active form (MoPhab A27. Flow cytometric analysis was performed both on a FACSCalibur, a standard flow cytometer, and on a Cell-Dyn Sapphire, a routine haematology analyser. Results. There was a high level of agreement between the two types of analysers, with 41% for FcγRIII, 80% for L-selectin, 98% for CD11b, and even a 100% agreement for active FcγRII. Moreover, analysis on the routine haematology analyser was possible in less than a quarter of the time in comparison to the flow cytometer. Conclusion. Analysis of neutrophil phenotype on the Cell-Dyn Sapphire leads to the same conclusion compared to a standard flow cytometer. The markedly reduced time necessary for analysis and reduced labour intensity constitutes a step forward in implementation of this type of analysis in clinical diagnostics in trauma research.

    Full Text Available Excessive use of oestrogen or ethinyl oestradiol (EO, a semisynthetic 17b-oestradiol as highly potent oestrogen can cause many detrimental effects, including cancer in humans as well as in animals. On the other hand, many herbal drugs are beneficial for the treatment of toxicity and cancer. Likewise, ProImmu and its plant-ingredients have been reported to possess immunomodulatory effect and restore the normal histoarchitecture of the damaged tissues. In the present study, the beneficial effects of ProImmu, and its two ingredients, viz., Tinospora cordifolia and Withania somnifera have been observed against EO altered haematological profiles in the female albino rats. The haematological study showed that EO (@ 250 μg/kg, orally, thrice a week altered levels of haemoglobin (Hb, total leucocyte count (TLC and differential leucocyte count (DLC- lymphocyte, monocyte, neutrophil and eosinophil could be significantly normalized by ProImmu (@ 150 mg/kg, orally, daily for 8 weeks; however, the normalization of these parameters brought up by T. cordifolia (@ 250 mg/kg, orally, daily for 8 weeks and W. somnifera (@ 250 mg/kg, orally, daily for 8 weeks was found to be of lesser degree. ProImmu (@150 mg/kg, orally, daily for 12 weeks, T. cordifolia (@250 mg/kg, orally, daily for 12 weeks and W. somnifera (@ 250 mg/kg, orally, daily for 12 weeks also caused the normalcy of these parameters, but to less extent than observed on the 8 weeks.

    Objective: To assess the haematological and lipid profile assays in asthmatics. Methods: Eighty asthmatic subjects were prospectively studied in a major referral centre serving the Niger Delta region of Nigeria for 12 months (2006-2007). Clinico-haematological and serum lipid total cholesterol (TC), triglyceride (TG), and lipoproteins concentration were analyzed after adjusting for age, cigarette smoking, alcohol ingestion, hypertension and diabetes mellitus. Results: Eighty patients (34 males and 46 females) were seen with female predominating in the various age groups (M∶ F ratio, 0.7∶ 1). Total cholesterol and low density lipoproteins-cholesterol for the asthmatics was significantly higher than the controls (P2.3mmol/L) and a significant hypercholesterolemia (HC, >5.2mmol/L) according to the Adult Treatment Panel III definition in asthmatics thereby putting them at increased risk for the development of cardiovascular disease as well as other disorders related to excess lipids. There was a significant thrombocytopenia (P<0.000 1) which may accompany allergen exposure and this persists for 24 h; that asthmatics of African descent showed a significantly increased total leucocyte count (P=0.001) similar to other studies in the Western countries. Conclusion: Hyperlipidaemia is a prevalent medical problem among asthmatics; hence screening for fasting serum lipid levels to identify those who need early intervention is recommended.

  7. Catatonic Symptoms Appearing before Autonomic Symptoms Help Distinguish Neuroleptic Malignant Syndrome from Malignant Catatonia.

    Komatsu, Takayuki; Nomura, Tomohisa; Takami, Hiroki; Sakamoto, So; Mizuno, Keiko; Sekii, Hajime; Hatta, Kotaro; Sugita, Manabu

    A 42-year-old Japanese woman with a 10-year history of schizophrenia was admitted due to a disturbance in consciousness that met the diagnostic criteria for both neuroleptic malignant syndrome (NMS) and malignant catatonia. Despite systemic supportive treatments, the catatonic symptoms preceding autonomic symptoms persisted. The symptoms improved after lorazepam administration, leading to a retrospective diagnosis of malignant catatonia. Catatonia is thought to be caused by a dysfunction of ganmma-aminobutyric acid type A receptors in the cortico-cortical networks of the frontal lobes, which causes hypoactivity of the dopaminergic transmission in the subcortical areas. Identifying the catatonic symptoms preceding autonomic symptoms could aid in distinguishing malignant catatonia from NMS.

  8. Malignant hyperthermia

    Full Text Available Abstract Malignant hyperthermia (MH is a pharmacogenetic disorder of skeletal muscle that presents as a hypermetabolic response to potent volatile anesthetic gases such as halothane, sevoflurane, desflurane and the depolarizing muscle relaxant succinylcholine, and rarely, in humans, to stresses such as vigorous exercise and heat. The incidence of MH reactions ranges from 1:5,000 to 1:50,000–100,000 anesthesias. However, the prevalence of the genetic abnormalities may be as great as one in 3,000 individuals. MH affects humans, certain pig breeds, dogs, horses, and probably other animals. The classic signs of MH include hyperthermia to marked degree, tachycardia, tachypnea, increased carbon dioxide production, increased oxygen consumption, acidosis, muscle rigidity, and rhabdomyolysis, all related to a hypermetabolic response. The syndrome is likely to be fatal if untreated. Early recognition of the signs of MH, specifically elevation of end-expired carbon dioxide, provides the clinical diagnostic clues. In humans the syndrome is inherited in autosomal dominant pattern, while in pigs in autosomal recessive. The pathophysiologic changes of MH are due to uncontrolled rise of myoplasmic calcium, which activates biochemical processes related to muscle activation. Due to ATP depletion, the muscle membrane integrity is compromised leading to hyperkalemia and rhabdomyolysis. In most cases, the syndrome is caused by a defect in the ryanodine receptor. Over 90 mutations have been identified in the RYR-1 gene located on chromosome 19q13.1, and at least 25 are causal for MH. Diagnostic testing relies on assessing the in vitro contracture response of biopsied muscle to halothane, caffeine, and other drugs. Elucidation of the genetic changes has led to the introduction, on a limited basis so far, of genetic testing for susceptibility to MH. As the sensitivity of genetic testing increases, molecular genetics will be used for identifying those at risk with

    This case report describes a 54-year-old man with bipolar I disorder who was treated with aripiprazole (ARP) and lithium. The patient was admitted to our hospital because of aggravation of depressive symptoms, and treatment with lamotrigine (LTG) was initiated. Two weeks after admission, we discontinued administration of ARP after the appearance of a tremor. Three weeks after discontinuing ARP, the patient developed a high fever, rigidity of the arms, diarrhea, dysphagia, and diaphoresis. We suspected these symptoms were consistent with neuroleptic malignant syndrome and therefore removed the application of LTG. After 2 days, most of the patient's symptoms and blood results had improved, leading us to conclude that the LTG treatment had induced neuroleptic malignant syndrome. Thus, the purpose of this case report was to warn psychiatrists against therapy with LTG, as it may be conducive to neuroleptic malignant syndrome.

  10. Exit and the duty to admit

    2015-10-01

    Full Text Available Conventionally, it is presumed that while citizens have the right to exit the state in which they are located, no particular state (except a citizen's home state is required to admit them. Yet, this convention has produced, and continues to produce, injustice; to understand why, I focus on defining and protecting a right to exit, as distinct from the right to move in general. This analysis leads me to propose that whereas the political theoretic literature appears to have converged on a commitment to decisive asymmetry (in favor of accepting a state's right to exclude, I propose that only a weak asymmetry is justified. I argue that receiving states are duty-bound to act in ways that enable migrants to exercise their right to exit. In particular, I argue that receiving states have a perfect duty to collectivize the process by which needy migrants can exercise the right to exit.

  11. Effects of Exercise Training on Haematology and Maximal Cardiac Output

    DEFF Research Database (Denmark)

    Bonne, Thomas Christian

    Qmax may increase within a few weeks of exercise and the underlying mechanisms leading to this are likely to be multi-factorial. Plasma volume is generally thought to rapidly increase in response to exercise training driving an increase in Qmax and hence VO2max. Structural and functional changes...... to the heart ultra structure possibly also play a role for improving Qmax. Other mechanisms that can improve exercise capacity include hypoxia. It is universally accepted that hypoxia is a main stimulant of erythropoiesis and altitude training is considered a possibility to increase red blood cell volume...... and hence exercise performance in elite athletes. However, the efficacy of altitude training for sea level performance is still debated and the literature is divergent on this matter. Even if the haematological changes following altitude training may be inadequate to substantially improve performance...

    Kawasaki disease is a multisystemic vasculitis that can result in coronary artery lesions. It predominantly affects young children and is characterized by prolonged fever, diffuse mucosal inflammation, indurative oedema of the hands and feet, a polymorphous skin rash and non-suppurative lymphadenopathy. Coronary artery involvement is the most important complication of Kawasaki disease and may cause significant coronary stenosis resulting in ischemic heart disease. The introduction of intravenous immunoglobulin decreases the incidence of coronary artery lesions to less than 5%. The etiopathogenesis of this disease remains unclear. Several lines of evidence suggest that an interplay between a microbial infection and a genetic predisposition could take place in the development of the disease. In this review, we summarize the state of the art of pathogenetic mechanisms of Kawasaki disease underscoring the relevance of haematological features as a novel field of investigation.

    William Hewson has been called the father of haematology. Initially working alongside the Hunter brothers in London in the mid-18th century, he advanced our knowledge of red and white cells (but mistakenly thought some red cells started as white cells and could not recognise different varieties of white corpuscles), showed that it was fibrinogen and not the cells that led to coagulation, greatly advanced our knowledge of the lymphatic system in humans, fishes and amphibians, explored the functions of the thymus and spleen and, investigated pneumothorax and surgical emphysema. His life, cut short at 35 years, was often intertwined with those of the Hunters, Alexander Monro secundus and Benjamin Franklin. This paper reviews his work, his relationships and his impact on a nascent science.

  15. Effects of Exercise Training on Haematology and Maximal Cardiac Output

    Bonne, Thomas Christian

    Qmax may increase within a few weeks of exercise and the underlying mechanisms leading to this are likely to be multi-factorial. Plasma volume is generally thought to rapidly increase in response to exercise training driving an increase in Qmax and hence VO2max. Structural and functional changes...... to the heart ultra structure possibly also play a role for improving Qmax. Other mechanisms that can improve exercise capacity include hypoxia. It is universally accepted that hypoxia is a main stimulant of erythropoiesis and altitude training is considered a possibility to increase red blood cell volume...... and hence exercise performance in elite athletes. However, the efficacy of altitude training for sea level performance is still debated and the literature is divergent on this matter. Even if the haematological changes following altitude training may be inadequate to substantially improve performance...

    To assess the gaps in the diagnosis and management of dengue fever cases. The retrospective descriptive analytical study was done with a case record analysis of patients with dengue fever admitted from January to December 2010 at five tertiary care hospitals in different Pakistani cities. Using a questionnaire, information was gathered on demography, haematological profile, management, use of blood and platelet transfusions and the outcome. For comparison, data of serologically-confirmed dengue patients from a private laboratory in Islamabad was collected to see the age, gender and month-wise distribution of cases tested over the same period. SPSS 16 was used for statistical analysis. Out of the 841 confirmed dengue cases, 514 (79%) were males and 139 (21%) females. The overall mean age was 31.3 +/- 14.0 years. Dengue fever was seen in 653 (78%) and dengue haemorrhagic fever (DHF) in 188 (22%) patients. Most cases were between 20 and 49 years of age. A gradual increase in dengue fever and dengue haemorrhagic fever was seen from August, with a peak in October/November. Tourniquet test was done only in 20 (2.3%) cases, out of which 11 (55%) were positive and 9 (45%) were negative. Serial haematocrit was not done in any case. Total deaths were 5 (0.6%). Most cases were seen in October/November with the majority being in the 20-39 age group. Tourniquet test and serial haematocrit were infrequently used. No standard national guidelines were employed.

    A recent framework of quantum theory with no global causal order predicts the existence of ‘causally nonseparable’ processes. Some of these processes produce correlations incompatible with any causal order (they violate so-called ‘causal inequalities’ analogous to Bell inequalities) while others do not (they admit a ‘causal model’ analogous to a local model). Here we show for the first time that bipartite causally nonseparable processes with a causal model exist, and give evidence that they have no clear physical interpretation. We also provide an algorithm to generate processes of this kind and show that they have nonzero measure in the set of all processes. We demonstrate the existence of processes which stop violating causal inequalities but are still causally nonseparable when mixed with a certain amount of ‘white noise’. This is reminiscent of the behavior of Werner states in the context of entanglement and nonlocality. Finally, we provide numerical evidence for the existence of causally nonseparable processes which have a causal model even when extended with an entangled state shared among the parties.

    Full Text Available Abstract Background Delirium is a neuropsychiatric syndrome frequently observed in elderly hospitalised patients and can be found in any medical condition. Due to the severe consequences, early recognition of delirium is important in order to start treatment in time. Despite the high incidence rate, the occurrence of delirium is not always identified as such. Knowledge of potential risk factors is important. The aim of the current study is to determine factors associated with the occurrence of a prevalent delirium among elderly patients acutely admitted to an internal medicine ward. Methods All consecutive patients of 65 years and over acutely admitted to the Department of Internal Medicine of the Academic Medical Centre, Amsterdam, a university hospital, were asked to participate. The presence of delirium was determined within 48 hrs after admission by an experienced geriatrician. Results In total, 126 patients were included, 29% had a prevalent delirium after acute admission. Compared to patients without delirium, patients with delirium were older, more often were cognitively and physically impaired, more often were admitted due to water and electrolyte disturbances, and were less often admitted due to malignancy or gastrointestinal bleeding. Independent risk factors for having a prevalent delirium after acute admission were premorbid cognitive impairment, functional impairment, an elevated urea nitrogen level, and the number of leucocytes. Conclusions In this study, the most important independent risk factors for a prevalent delirium after acute admission were cognitive and physical impairment, and a high serum urea nitrogen concentration. These observations might contribute to an earlier identification and treatment of delirium in acutely admitted elderly patients.

    Full Text Available Haematological traits are important traits that show associations with immune and metabolic status, as well as diseases in humans and animals. Mapping genome regions that affect the blood cell traits can contribute to the identification of genomic features useable as biomarkers for immune, disease and metabolic status. A genome-wide association study (GWAS was conducted using PorcineSNP60 BeadChips. Single-marker and Bayesian multi-marker approaches were integrated to identify genomic regions and corresponding genes overlapping for both methods. GWAS was performed for haematological traits of 591 German Landrace pig. Heritability estimates for haematological traits were medium to high. In total 252 single SNPs associated with 12 haematological traits were identified (NegLog10 of p-value > 5. The Bayesian multi-marker approach revealed 102 QTL regions across the genome, indicated by 1-Mb windows with contribution to additive genetic variance above 0.5%. The integration of both methods resulted in 24 overlapping QTL regions. This study identified overlapping QTL regions from single- and multi-marker approaches for haematological traits. Identifying candidate genes that affect blood cell traits provides the first step towards the understanding of the molecular basis of haematological phenotypes.

    Full Text Available Objective. Vaccinations are the most important tool to prevent infectious diseases. Chemotherapy-induced immune depression may impact the efficacy of vaccinations in children. Patients and Methods. A panel of experts of the supportive care working group of the Italian Association Paediatric Haematology Oncology (AIEOP addressed this issue by guidelines on vaccinations in paediatric cancer patients. The literature published between 1980 and 2013 was reviewed. Results and Conclusion. During intensive chemotherapy, vaccination turned out to be effective for hepatitis A and B, whilst vaccinations with toxoid, protein subunits, or bacterial antigens should be postponed to the less intensive phases, to achieve an adequate immune response. Apart from varicella, the administration of live-attenuated-virus vaccines is not recommended during this phase. Family members should remain on recommended vaccination schedules, including toxoid, inactivated vaccine (also poliomyelitis, and live-attenuated vaccines (varicella, measles, mumps, and rubella. By the time of completion of chemotherapy, insufficient serum antibody levels for vaccine-preventable diseases have been reported, while immunological memory appears to be preserved. Once immunological recovery is completed, usually after 6 months, response to booster or vaccination is generally good and allows patients to be protected and also to contribute to herd immunity.

    A detailed audiological study combined with certain haematological investigations which were never previously done was undertaken on Todas, a small vanishing tribe of Nilgiris, South India. Ten per cent of the Todas studied exhibited otosclerosis which, though lower than that of a previous study, is still a very high percentage when compared to the general population. The incidence of chronic suppurative otitis media in Todas is markedly low (1-6 per cent) and 13-3 per cent of Todas had sensorineural hearing loss. Evaluation of hearing thresholds at various frequencies in the different age groups did not show much variation from that of the general population. The incidence of presbyacusis is not found to be low as reported earlier. Blood pressure recordings did not show any age-related increase. The majority of Todas studied belonged to the blood group 'B' (63 per cent) and 16-6 per cent belonged to the 'AB' group, which is distinctly different from the distribution pattern seen in the general Indian population. There was no significant variation in the serum cholesterol level in Todas.

    Peromyscus leucopus mice share physical similarities with laboratory mice Mus musculus (MM) but have higher agility and longer lifespan. We compared domesticated P. leucopus linville (PLL) and M. musculus C57BL/6 (MMB6) mice for cellular composition of peripheral blood (PB), bone marrow (BM) and spleen. PLL mice had significantly fewer platelets and significantly more monocytes in the blood, and notably fewer megakaryocytes in the BM. Spleens of PLL mice were significantly smaller, with 50% fewer cells and reduced 'red pulp'. There was no obvious haematological change in PLL mice between 2-8 and 16-26 months of age, except for a significant increase in blood monocytes. Cellular reactive oxygen species (ROS) content showed no change with age but differed significantly between different cell types. Treating two to eight month-old PLL mice with antioxidant N-acetylcysteine in drinking water for three months did not affect cellular ROS content, but increased blood leucocytes especially the concentration of monocytes. The low platelets, low megakaryocytes, high monocytes and low splenic erythropoiesis in PLL mice resemble human measurements better than the values seen in MMB6.

    A common trend in higher education is the "flipped" classroom, which facilitates active learning during class. The flipped approach to teaching was instituted in a haematology `major' class and the students' attitudes and preferences for the teaching materials were surveyed. The curriculum design was explicit and involved four major components (1) the preparation of the students; (2) the weekly pre-class work; (3) the in-class active learning strategies and (4) closing the learning loop using formative quizzes. Each of these components is discussed in detail and was informed by sound pedagogical strategies. Several different sources of information and several freely available software tools to engage the students are discussed. Two iterations are reported here, with improved pass rate for the final examination from 47 to 48 % in the traditional class to 56-65 % in the flipped classroom approach. The majority of students (93 and 89 %) came to the class prepared, after viewing the screencasts and engaged fully with the activities within the face-to-face time. The students perceived that solving case studies (93 %) was the most beneficial activity for their learning and this was closely followed by the production of essay plans (71 %). The majority of students recommended that this approach be repeated the following year (69 and 75 %).

The aim of this study is to evaluate hematological parameters for captive harpy eagles maintained at the wild animals breeding center of Itaipu Binacional, Paraná State, Brazil. Fourteen blood samples from nine harpy eagles were collected from animals of both sexes, of different ages and with no clinical signs of disease. Significant variations were found in haematological values of hematocrit, hemoglobin, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC, leukocyte, a relative number of heterophils, absolute and relative number of lymphocytes, monocytes, eosinophils, basophils and plasma protein between groups of young (less than six months old and adult birds. Comparing males and females there was variation in the values of erythrocytes, hemoglobin, mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH on heterophils, absolute and relative number of lymphocytes, eosinophils and basophils. There was also variation in the values of red blood cells, hematocrit, hemoglobin, mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC, leukocyte count, absolute number of lymphocytes, eosinophils and basophils among birds that study compared to another reference birds. Due to the limited information available on harpy eagle hematology, this study will be useful to the clinical assessment of birds maintained in captivity.

    The German Society for Paediatric Oncology and Haematology (GPOH) runs nation-wide multicentre clinical trials to improve the treatment of children suffering from malignant diseases. We want to provide methods and tools to support the centres of these trials in developing trial specific modules for the computer-based DOcumentation System for Paediatric Oncology (DOSPO). For this we carried out an object-oriented business process analysis for the Cooperative Soft Tissue Sarcoma Trial at the Olgahospital Stuttgart for Child and Adolescent Medicine. The result is a comprehensive business process model consisting of UML-diagrams and use case specifications. We recommend the object-oriented business process analysis as a method for the definition of requirements in information processing projects in the field of clinical trials in general. For this our model can serve as basis because it slightly can be adjusted to each type of clinical trial.

    To evaluate various haematological parameters, individually and in combination, to formulate a haematological scoring system (HSS, defined by Rodwell et al.), which can then be used to screen for sepsis in neonates who are clinically suspected of infection.1 The study cohort consisted of 150 neonates (from birth to 3 days old) with clinically suspected infection. Blood was collected by peripheral venepuncture in all neonates. A complete blood count, differential leucocyte count, total leucocyte count (TLC), total neutrophil count (TNC), immature neutrophil count, band form count and platelet count were performed. Immature total neutrophil count (I/T) and immature/mature neutrophil count (I/M) ratios were then obtained. C-reactive protein (CRP) was measured semiquantitatively and blood culture and antibiotic sensitivity were performed in each case. The haematological parameters were compared individually and in combination (by HSS) with CRP. Twenty-one (14%) neonates had blood culture proven sepsis. On evaluation of various haematological parameters, TLC 0.25, I/T > 0.14, band count > 15% and platelet count or = 3 had a sensitivity of 86% and NPV of 96%. C-reactive protein as a single test had a sensitivity of 76% and NPV of 96%. A combination of CRP with haematological parameters decreased the sensitivity and NPV of the HSS. A haematological score can be obtained by a complete blood count and examination of peripheral blood smear, thus permitting an objective assessment of haematological changes that occur in a neonate suspected of sepsis. C-reactive protein does not have any advantage over HSS, either as a single test or in combination.

    Nowadays, the number of cases in which malignant colorectal polyps are removed is increasing due to colorectal cancer screening programmes. Cancerous polyps are classified into non-invasive high grade neoplasia (NHGN), when the cancer has not reached the muscularis mucosa, and malignant polyps, classed as T1, when they have invaded the submucosa. NHGN is considered cured with polypectomy, while the prognosis for malignant polyps depends on various morphological and histological factors. The prognostic facto...

    Dehydration can be extremely damaging to the performance and welfare of indigenous chickens. The effect of water restriction on haematological and biochemical parameters was compared in Naked Neck (NNK) and Ovambo (OVB) chickens. A total of 54 8-week-old pullets each of NNK and OVB chickens with an initial average weight of 641 ± 10 g/bird were randomly assigned to three water intake treatments with three replications, each having six birds. The water restriction treatments were ad libitum, 70% and 40% of ad libitum intake. Nine experimental pens with a floor space of 3.3 m2 per strain were used. Feed was provided ad libitum. Packed cell volume (PCV), erythrocyte count (RBC), mean corpuscular volume (MCV) and total leucocyte count (WBC), and biochemical parameters (uric acid (UA)), creatinine (CREAT), total protein (TP), albumin (ALB), globulin (GLOB), triglyceride (TGA), total cholesterol (TC), high- (HDLC) and low- (LDLC) density lipoprotein cholesterol and activity of alanine transaminase (ALT), alkaline phosphatase (ALP) and aspartate transaminase (AST) were determined from blood collected after 60 days of water restriction. PCV was higher (P chickens offered water ad libitum, but similar in birds offered 70% and 40% of ad libitum. There were no differences in RBC and MCV values between strains, but MCV was higher in birds on 40% than 70% of ad libitum water intake, irrespective of strain. Naked neck chickens had higher (P chickens. The opposite was observed for UA. ALT activity indicated that liver function was not affected by water restriction. It was concluded that the two strains can withstand up to 40% of ad libitum water restriction, but NNK tolerated water stress better than OVB chickens.

    Paragangliomas are rare, typically benign neuroendocrine tumors that represent a small portion of head and neck tumors. A small percentage of these are known to have malignant potential. They arise from the carotid body, jugular bulb or vagus nerves. There is limited literature discussing the management of malignant vagal paragangliomas. We present a case of a 25 year old female with a left malignant vagal paraganglioma. The following case presentation will describe the presentation, classic radiologic findings, and management of a malignant vagal paraganglioma along with a review of the literature.

    The characteristic pathological muscular findings of polymyositis (PM) and dermatomyositis (DM) have been shown to reflect their different pathogeneses. Here, we characterized the muscle biopsy findings of PM and DM patients with or without malignancy. We evaluated the muscle biopsy findings of 215 consecutive PM and DM patients admitted to our hospital between 1970 and 2009. Pathology of the lesion biopsy sections was classified into 3 types: endomysial infiltration-type, perivascular infiltration-type, and rare-infiltrative-type. There was no difference between the muscle pathology of PM patients with and without malignancy. However, the incidence of rare-infiltrative type muscle pathology in DM patients with malignancy was significantly higher than in those without such tumors (p=0.0345). The incidence of rare-infiltrative type muscle pathology may be a predictive marker of DM with malignancy. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available The aim of the study was to determine the values of selected haematological indices of the Polbar breed of chickens by gender and age. There was a significant WBC difference in cocks and hens with age. In each of the periods, cocks were characterized by a lower than hens number of LY. LY and NE declined with increasing age. Most values showed significant (P ≤ 0.05 differences for birds at different ages. These results of the haematological indices from consolidated Polbar breed can be used for comparisons with other breeds of poultry. The study deepens and organizes the knowledge within the possibilities of using and interpreting levels of haematological indicators for monitoring health of hens. In this paper, we managed to obtain information on the level of indicators rarely determined in chickens.

They were adult patients who had been diagnosed of various malignancies, consisting of Breast cancer 36 patients (45%), Non-Hodgkin's iymphoma 8 (10%), Hodgkin's lymphoma 13 (16.25%), Colorectal carcinoma 6 (7.5%), Multiple myeloma 7 (8.75%), Cervical carcinoma 1 (1.25%) and other malignancies 9 (11.25%). Haematological indices evaluated include: packed cell volume, haemoglobin concentration; total white blood cell count, platelet count and erythrocyte sedimentation rate. The socio demographic data of the patients were assessed from a questionnaire. There were 27 males (33.75%) and 53 females (66.25%). The age of the patients ranged from 18-80 years with a median of 45 years. Haematological parameters which were found to be significantly reduced include: haemoglobin concentration, packed cell volume and total white cell count.

    Characteristics associated with familial compared with nonfamilial malignant melanoma were assessed. These data were obtained from consecutive prospectively completed questionnaires on 1169 cases of cutaneous malignant melanoma. Of these, 69 patients indicated a positive family history for this cancer. Among the various clinical and histological variables compared, those that significantly correlated with the familial occurrence of malignant melanoma include younger age at first diagnosis, smaller diameter of the lesion, lower Clark level, decreased frequency of nonmelanoma skin cancer, and reduced prevalence of noncutaneous cancer. Increased awareness of malignant melanoma among family members could account for some of these observations. Identification of the familial variety of malignant melanoma has practical implications concerning early detection and prompt intervention.

  7. Giving AXL the axe: targeting AXL in human malignancy

    Science.gov (United States)

    Gay, Carl M; Balaji, Kavitha; Byers, Lauren Averett

    2017-01-01

    The receptor tyrosine kinase AXL, activated by a complex interaction between its ligand growth arrest-specific protein 6 and phosphatidylserine, regulates various vital cellular processes, including proliferation, survival, motility, and immunologic response. Although not implicated as an oncogenic driver itself, AXL, a member of the TYRO3, AXL, and MERTK family of receptor tyrosine kinases, is overexpressed in several haematologic and solid malignancies, including acute myeloid leukaemia, non-small cell lung cancer, gastric and colorectal adenocarcinomas, and breast and prostate cancers. In the context of malignancy, evidence suggests that AXL overexpression drives wide-ranging processes, including epithelial to mesenchymal transition, tumour angiogenesis, resistance to chemotherapeutic and targeted agents, and decreased antitumor immune response. As a result, AXL is an attractive candidate not only as a prognostic biomarker in malignancy but also as a target for anticancer therapies. Several AXL inhibitors are currently in preclinical and clinical development. This article reviews the structure, regulation, and function of AXL; the role of AXL in the tumour microenvironment; the development of AXL as a therapeutic target; and areas of ongoing and future investigation.

    Malignant mesothelioma (mesothelioma) is rare. We conducted the first systematic study of the epidemiology of mesothelioma in Hong Kong from 1988 to May 2002 by reviewing medical records. Mesothelioma patients were identified from the database of 12 out of 20 hospitals that would have admitted mesothelioma patients territory-wide. These 12 hospitals served 73% of the total hospital bed-years of the 20 hospitals. We identified 67 mesothelioma patients. The estimated annual incidence was one per million, which was similar to the background incidence of one to two per million among Caucasians. Occupational history was available in 43 subjects. Three quarters of mesothelioma patients with available occupational history had occupational asbestos exposure. Restricting analysis to 48 patients with accessible medical records and using 67 occupational asbestosis patients for comparison, the epidemiology of mesothelioma in Hong Kong shares similarities with the literature: mean age of 63 years upon diagnosis, mean latency of 46 years, median survival of 9.5 months, male predominance, selective presentation among women, high prevalence among workers in ships and dockyards, predominantly epithelioid type, lower prevalence of asbestos bodies, and negative association with pleural plaques. Asbestos consumption in Hong Kong rose in the 1970s and peaked in early 1980s and late 1990s. Hong Kong may encounter an epidemic of mesothelioma in the 2010s if effective occupational asbestos control measures are not in place.

    We report a case of malignant catatonia initially diagnosed as neuroleptic malignant syndrome (NMS) that responded successfully to diazepam administration. A 29-year-old man with mental retardation was admitted to our hospital because of high fever, muscle pain, and consciousness disturbance. Fifteen days before admission, he had developed muscle pain and weakness in his legs. He presented with fever, tachycardia, tachypnea, elevated blood pressure, excessive sweating, and neurological findings of lethargy and severe muscle rigidity in the neck and extremities. Laboratory findings included elevated serum creatine phosphokinase (CPK) level. His clinical features and the laboratory test results fulfilled the diagnostic criteria for NMS. He was treated for NMS with dantrolene sodium and bromocriptine mesylate for 2 weeks; however, there was no improvement. Therefore, treatment was changed to diazepam administration because of suspected malignant catatonia. One week after initiation of diazepam administration, his symptoms gradually improved, and the serum CPK level normalized. The diagnosis of malignant catatonia was confirmed because treatment with diazepam was dramatically effective, whereas the initial treatment for NMS was not beneficial. The clinical presentation of malignant catatonia is similar to that of NMS. Indeed, some authors have described NMS as a variant of malignant catatonia. If treatment is refractory in cases of NMS, malignant catatonia may be suspected, and changing treatment to diazepam administration may be useful.

    Full Text Available Aim: To evaluate the important haematological values of the retrospective clinical cases of buffaloes presented to the Teaching Veterinary Hospital of the College of Veterinary Science, Guru Angad Dev Veterinary and Animal Science University, Ludhiana over a period of 4 years from January 2007 to December 2010. Materials and methods: The blood was collected from jugular vein in EDTA containing vials. Statistical analysis of haematological values with different case history/clinical signs was performed using SPSS 16.0 version by applying one way ANOVA at P<0.05. Clinical pathology of these cases was monitored by comparing hemogram values with the reference range. Results: The most common disorders found in water buffaloes were digestive disorders followed by fever and respiratory disorders. Haematological values viz. TLC, DLC (neutrophil, lymphocyte and eosinophil counts showed significant differences depending upon the case history/clinical signs while haemoglobin count was found to be statistically nonsignificant. Conclusion: TLC and DLC are found to be the important indicators of health status of water buffaloes in general which are more related to clinical history/clinical signs of this species than other the haematological parameters viz. haemoglobin count.

    In the long-term biomonitoring of wild populations inhabiting polluted areas, the use of non-destructive biomarkers as markers of condition is very important. We examined the possible effects of metal pollution on the haematological status of adult great tits (Parus major) along a well-established pollution gradient near a non-ferrous smelter in Belgium. We measured blood and feather metal concentrations and assessed the haematological status (amount of red blood cells, haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin) of adult great tits during winter at four study sites. Metal concentrations in blood and feathers indicated that cadmium and lead were the most important metals in the pollution gradient under study. Measurements of haematological parameters revealed that haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin were lower in great tits from the more polluted sites. These parameters were significantly negatively correlated with blood lead concentration. The amount of red blood cells, however, did not significantly differ among study sites. Our results indicate that the haematological status of great tits is negatively affected by metal pollution and may therefore be used as a successful biomarker for monitoring the negative impact of metal exposure in the wild.

    Full Text Available Haematological analyses has been routinely used in determining the physiological state of animals and known to be affected by different environmental factors, the present study was therefore designed to assess the effect of 24 hours of light (00D: 24L, 24 hours of darkness (24D: 00L and 12 hour light / 12 hours darkness (12D: 12L photoperiod on the haematological parameters of the African Catfish. At the end of the six weeks experiment, it was observed that some haematological parameters such as Mean Corpuscular Haemoglobin Concentration (MCHC, the Mean White Blood Cells (WBC, Mean Red Blood Cells (RBC, Haemoglobin content (HGB, Platelet count (PLT showed significant difference (P0.05. However MCHC and MCH were noticed to increase as the light period increased while the other parameters reduced as the light period increased. The findings indicate that exposure of the African Catfish to continuous light for six weeks duration elicits response in the haematological profile of the fish.

Although no serious side effects have been reported, there is no information available about the effects of the medicine on haematological parameters. For the first time clinical and ultrasonographic features and haematological profiles were evaluated in rabbits treated with aglepristone 15 and 16 days after mating. Ten healthy 10–14 month-old New Zealand White female rabbits were mated with fertile bucks and pregnancies were confirmed by ultrasound 15 days later. Of these, 5 does were treated with aglepristone (test group, n = 5 whilst the remaining five (control group, n = 5 were treated with a saline solution (0.9% NaCl. The treatment dose was 10 mg⁄kg body weight, administered subcutaneously once daily on two consecutive days (day 15 and 16 post mating. Ultrasonographic, clinical and haematological assessments were performed daily. Aglepristone treatment induced embryonic fluid resorptions without foetal death in mid-gestation terminations. Following ultrasonographic and haematological examinations, it was established that aglepristone is a safe abortifacient in rabbits.

    Full Text Available Malignancy is the second most common cause of mortality in the reproductive period and it complicates up to one out of every 1000 pregnancies. When cancer is diagnosed during pregnancy, the management approach must take into consideration both the mother and her fetus. Hematologic cancers diagnosed in pregnancy are not common, resulting in paucity of randomized controlled trials. Diagnosis of such malignancies may be missed or delayed, as their symptoms are similar to those encountered during normal pregnancy. Also, many imaging studies may be hazardous during pregnancy. Management of these malignancies during pregnancy induces many treatment-related risks for mother and baby and should consider patient’s preferences for pregnancy continuation. In this article, hematologic malignancies diagnosed in pregnant patients including acute leukemias, chronic myeloid leukemia, lymphomas, multiple myeloma and myeloproliferative neoplasms, will be reviewed, including diagnostic and management strategies and their impact on the pregnant patient and the developing fetus.

    investigations were done: Blood counts, IgM Dengue. Clinically, patients were monitored and platelet count, haematocrit, Hess test were repeated daily. DATA ANALYSIS Data collected will be analysed by frequency, percentage and mean. Dengue-IgM Capture ELISA Detection of dengue virus specific IgM Antibodies in serum. RESULTS Male to female ratio was 1.5:1. Majority of the cases having dengue infection belong to the age group of 21-30 years, wherein 48% belong to 21-30 years’ group and 24% belong to 31-40 years’ group. All the cases had fever (100%. Other common signs and symptoms included are myalgia (85%, headache (80%, joint pains (76%, vomiting (60%, pain abdomen (54%, rash (46%, hepatomegaly (25%, bleeding (21% and shock (5%. Signs suggestive of plasma leakage such as pedal oedema (12%, ascites (20%, pleural effusion (26% were present. Hess test was positive in 20% of the patients. Thrombocytopenia was found in 76% patients. Bradycardia was found in 41 %. CONCLUSIONS The present study had an objective of studying clinical manifestations and haematological profile associated with dengue fever. A positive Hess test should prompt close observation and early hospital referral, but a negative test does not exclude dengue infection. Bleeding tendencies should be closely watched for. When features of plasma leakage such as pedal oedema, pleural effusion, ascites are present, the patient should be closely watched for and should be immediately managed. The treatment of dengue is mainly supportive. However, appropriate fluid management plays a major role in outcome of the disease. Dengue sero-surveillance studies may give some idea about advent, intensity, transmission season, seasonal incidence, waxing and waning, and impending epidemic of dengue and DHF. A large-scale active longitudinal sero-survey along with the study of vector capacity and vector competence would provide more correct information.

    Fungal infections are recognized in an increasing number of patients with immunological deficits and are associated with high rates of mortality (Brown et al., 2012a). In this pilot-study, a rapid Real time PCR (fuPCR) was designed for the detection and differentiation of fungal pathogens in clinical specimens of haematological patients. The fuPCR, targeting the internal transcribed spacer region 2 (ITS2) of rDNA region, is comprised of seven multiplex reactions, which were shown to be specific and sensitive for a comprehensive spectrum of clinically relevant fungal species. This was validated by testing respective fungal DNAs in each fuPCR reaction and 28 respiratory samples of fungal pneumonia-proven patients. Clinical sample sets of throat swab, EDTA-blood and blood sera from 50 patients with severe haematological malignancies, including haematopoietic stem cell transfer (HSCT), and samples from 30 healthy individuals were then analysed. In a first step, 198 samples of immunosuppressed patients were solely examined by fuPCR; and 50.8% (33/65) respiratory swabs, 4.8% (3/63) EDTA blood samples and 1.4% (1/70) blood serum samples were tested positive. In a second step, 56 respiratory samples of immunosuppressed patients and 30 of healthy individuals were simultaneously analysed by fuPCR and standard cultivation techniques. By both methods 30.4% (17/56) swabs of the immunocompromised patients were tested positive, 37.5% (21/56) were tested negative and 32.1% (18/56) were tested fuPCR positive and culture negative. In analysing the blood samples of the immunocompromised patients 5.4% (3/56) EDTA blood samples and 16.1% (9/56) sera samples were tested fuPCR-positive, whereas all samples of 30 healthy individuals with no signs of immunological deficits were tested negative by fuPCR. 38.9% (14/36) of the fungi detected in respiratory samples of the immunosuppressed patients, belonged to Candida spp., 47.2% (17/36) to Saccharomyces spp., 5.6% (2/36) to Cladosporium spp

    Full Text Available An affine hypersurface M is said to admit a pointwise symmetry, if there exists a subgroup G of Aut(T_pM for all p in M, which preserves (pointwise the affine metric h, the difference tensor K and the affine shape operator S. Here, we consider 3-dimensional indefinite affine hyperspheres, i.e. S = HId (and thus S is trivially preserved. In Part 1 we found the possible symmetry groups G and gave for each G a canonical form of K. We started a classification by showing that hyperspheres admitting a pointwise Z_2 × Z_2 resp. R-symmetry are well-known, they have constant sectional curvature and Pick invariant J < 0 resp. J = 0. Here, we continue with affine hyperspheres admitting a pointwise Z_3- or SO(2-symmetry. They turn out to be warped products of affine spheres (Z_3 or quadrics (SO(2 with a curve.

    2008-01-01

    Destructive bone lesions occurring in patients who have previously had a malignancy are generally assumed to be a metastasis from that malignancy. We reviewed 60 patients with a previous history of malignancy, who presented with a solitary bone lesion that was subsequently found to be a new and different primary sarcoma of bone. These second malignancies occurred in three distinct groups of patients: (1) patients with original tumours well known to be associated with second malignancies (5%); (2) patients whose second malignancies were likely to be due to the previous treatment of their primary malignancy (40%); (3) patients in whom there was no clearly defined association between malignancies (55%). The purpose of this study is to emphasise the necessity for caution in assuming the diagnosis of a metastasis when a solitary bone lesion is identified following a prior malignancy. Inappropriate biopsy and treatment of primary bone sarcomas compromises limb salvage surgery and can affect patient mortality. PMID:18414590

The purpose of this study is to emphasise the necessity for caution in assuming the diagnosis of a metastasis when a solitary bone lesion is identified following a prior malignancy. Inappropriate biopsy and treatment of primary bone sarcomas compromises limb salvage surgery and can affect patient mortality.

    To determine the effect of delayed umbilical cord clamping on Hb (haemoglobin) and bilirubin levels of neonates and to identify newborn babies with anaemia and refer them for treatment. This Randomized Controlled Trial was conducted in the Department of Obstetrics and Gynaecology, Unit V, Dow Medical College and Lyari General Hospital and Department of Pathology, Lyari General Hospital, between 1st November, 2006 and 15th July, 2007. Patients admitted to labour ward were selected according to inclusion criteria of the study. They were randomly allocated to 2 groups. Group A included women in whom umbilical cord was clamped immediately after birth. In Group B, clamping was delayed until cessation of pulsations in the cord. After cutting the cord, sample of blood was collected from the cut end of cord of the newborn for Hb and bilirubin. After 6 hours of birth, another sample of blood was drawn from antecubital vein for serum bilirubin. Samples were sent to laboratory for analysis. All data were entered and analyzed using SPSS version 11. Two hundred women were studied, 100 in each of the 2 groups. Mean maternal Hb was 9.75 g/dl in Group A and 9.95 g/dl in Group B. The average neonatal Hb was 14.1 g/dl in Group A and 15.2 g/dl in Group B (p = 0.008). In all 49% neonates in Group A and 37% in Group B had Hb umbilical cord clamping at birth seems to be safe and can be expected to reduce the prevalence of anaemic newborn babies in our community.

    The most frequent malignant salivary gland tumours are the mucoepidermoid tumour, adenoid cystic carcinoma and adenocarcinoma. The major salivary glands and the minor glands of the mouth and upper respiratory tract may potentially develop any of these malignant lesions. Malignant lesions most frequently present as a palpable mass and tend to enlarge more rapidly than benign neoplasms. Pain, paresthesia, muscle paralysis and fixation to surrounding tissue are all ominous signs and symptoms. The only reliable means of differential diagnosis of these lesions is biopsy and histologic analysis. Therapy involves surgery or a combination of surgery and radiation therapy. The ultimate prognosis is governed by the intrinsic biologic behaviour of the neoplasms, the extent of disease and adequate clinical therapy.

    Gastrointestinal (GI) malignancies are notorious for frequently progressing to advanced stages even in the absence of serious symptoms,thus leading to delayed diagnoses and dismal prognoses.Secondary prevention of GI malignancies through early detection and treatment of cancer-precursor/premalignant lesions,therefore,is recognized as an effective cancer prevention strategy.In order to efficiently detect these lesions,systemic application of screening tests (surveillance) is needed.However,most of the currently used non-invasive screening tests for GI malignancies (for example,serum markers such as alpha-fetoprotein for hepatocellular carcinoma,and fecal occult blood test,for colon cancer) are only modestly effective necessitating the use of highly invasive endoscopy-based procedures,such as esophagogastroduodenoscopy and colonoscopy for screening purposes.Even for hepatocellular carcinoma where non-invasive imaging (ultrasonography) has become a standard screening tool,the need for repeated liver biopsies of suspicious liver nodules for histopathological confirmation can't be avoided.The invasive nature and high-cost associated with these screening tools hinders implementation of GI cancer screening programs.Moreover,only a small fraction of general population is truly predisposed to developing GI malignancies,and indeed needs surveillance.To spare the average-risk individuals from superfluous invasive procedures and achieve an economically viable model of cancer prevention,it's important to identify cohorts in general population that are at substantially high risk of developing GI malignancies (riskstratification),and select suitable screening tests for surveillance in these cohorts.We herein provide a brief overview of such high-risk cohorts for different GI malignancies,and the screening strategies that have commonly been employed for surveillance purpose in them.

    Objective: To investigate the haematology and biochemistry values of apparently healthy captive sand cats kept in Al Ain Wildlife Park and Resort, United Arab Emirates, with a view to establishing baseline values.Methods:Blood was collected from the femoral vein using aseptic techniques, kept in a cool box and sent to laboratory for analysis. The blood was analysed for haematological and biochemical values using veterinary hematology and chemistry analysers (ABX ABC Vet, Horiba ABX SAS Montpellier, France). Results: Haematological values were within the normal ranges recorded in domestic cats and there was no statistical difference between values found in males and females. Aspartate aminotransferase values were higher (P0.05) between males and females values.Conclusions:Our results present reference ranges for haematology and biochemistry parameters in captive sand cats. These values will be important for diagnosis of various diseases and monitoring of treatments.

    We report a patient with neuroleptic malignant syndrome (NMS) who developed acute renal failure and was successfully treated by hemodialysis. A 60-year-old man with a 26-year history of schizophrenia had been treated with thioridazine and sulpiride. He was admitted to our hospital for muscular rigidity and oliguria. After the diagnosis of NMS with acute renal failure was established, thioridazine and sulpiride were discontinued and hemodialysis was instituted. Renal function gradually improved and hemodialysis was discontinued after 17th treatment. We also reviewed 57 cases of NMS with acute renal failure reported in the literature. To our knowledge, 26 years is the longest latency between initiation of neuroleptic drug treatment and onset of NMS. Our review of reported NMS cases with acute renal failure identified those risks for poor prognosis as high level of BUN, age and female gender.

    Full Text Available Most cancer patients are treated with some combination of surgery, radiation, and chemotherapy. Despite recent advances in local therapy with curative intent, chemotherapeutic treatments for metastatic disease often remain unsatisfying due to severe side effects and incomplete long-term remission. Therefore, the evaluation of novel therapeutic options is of great interest. Conventional, along with newer treatment strategies target the immune system that suppresses genitourinary (GU malignancies. Metastatic renal cell carcinoma and non-muscle-invasive bladder caner represent the most immune-responsive types of all human cancer. This review examines the rationale and emerging evidence supporting the anticancer activity of immunotherapy, against GU malignancies.

    Full Text Available Purpose: Trauma is one of the most common reason of admissions to emergency departments. In this study, it was aimed to determine the demographic characteristics, etiology, morbidity and mortality rates and prognosis of adult trauma patients admitted to our emergency department (ED. Materials and Methods: Patients over the age of 18 years, who admitted to ED between 01 March 2011 and 31 August 2011 were included in this retrospective study. Patient examination cards, hospitalization files and records entered with ICD 10 codes to hospital automation system were analyzed. Patients with inaccessible data were excluded from the study. Results: During the study period, total number of 110495 patients admitted to ED, and 13585 (12,29% of them admitted with trauma. Simple extremity injuries (38,28% and falls (31,7% were most common etiological factors. Glasgow coma scales of 99,71% of the patients were between 13 and 15. Of the patients with trauma, 9,6% had a Computed Tomography (CT scan, and 84,5% of CT scans were evaluated as normal, and cranial CT was the most requested one. Only 6% of the patients were hospitalized, and 0,9% of the trauma patients died. Falls from height in females and traffic accidents in males were the leading causes of death. Conclusion: Most of the patients with simple traumas admitted to ED can be discharged from the hospital with a complete history and careful examination. The rate of unnecessary medical tests, loss of time and waste money should be reduced, and the time and labor allocated to severe patients can be increased by this way.

    To identify the factors associated with prolonged length of hospital stay in patients admitted for acute heart failure. Multipurpose observational cohort study including patients from the EAHFE registry admitted for acute heart failure in 25 Spanish hospitals. Data were collected on demographic and clinical variables and on the day and place of admission. The primary outcome was length of hospital stay longer than the median. We included 2,400 patients with a mean age of 79.5 (9.9) years; of these, 1,334 (55.6%) were women. Five hundred and ninety (24.6%) were admitted to the short stay unit (SSU), 606 (25.2%) to cardiology, and 1,204 (50.2%) to internal medicine or gerontology. The mean length of hospital stay was 7.0 (RIC 4-11) days. Fifty-eight (2.4%) patients died and 562 (23.9%) were readmitted within 30 days after discharge. The factors associated with prolonged length of hospital stay were chronic pulmonary disease; being a device carrier; having an unknown or uncommon triggering factor; the presence of renal insufficiency, hyponatremia and anaemia in the emergency department; not being admitted to an SSU or the lack of this facility in the hospital; and being admitted on Monday, Tuesday or Wednesday. The factors associated with length of hospital stay≤7days were hypertension, having a hypertensive episode, or a lack of treatment adherence. The area under the curve of the mixed model adjusted to the center was 0.78 (95% CI: 0.76-0.80; p<0.001). A series of factors is associated with prolonged length of hospital stay and should be taken into account in the management of acute heart failure. Copyright © 2016 SESPAS.

    The effects of the Ginseng extract on various biochemical and haematological parameters in male Wistar rats subjected to a treadmill exercise protocol were studied for 12 weeks. The results showed increases in the haematological parameters, these increases being greatest for the animals treated with the extract during the third month of the study. The exercise also led to increases in these parameters, while the combination of both exercise and extract produced smaller increases. This study shows a clear physiological response due to the ginseng extract administration that reproduces many of the effects obtained after long-term exercise. The combination of exercise and treatments seems to support the theory that there is no clear synergic effect when the advantages associated with the ingestion of ginseng are compared with the performance of exercise.

    Wild Nile crocodiles (Crocodylus niloticus) of various size classes were captured in the Okavango Delta, Botswana. Blood was collected from the post occipital sinus and used for the determination of a wide range of haematological and biochemical parameters. These values were compared between the sexes and between 3 size classes. The values were also compared with the limited data available from farmed Nile crocodiles, as well as from other wild Nile crocodiles. The Okavango crocodiles were comparatively anaemic, and had comparatively low total protein and blood glucose levels. There was a high prevalence of Hepatozoon pettiti infection, however, there was no significant difference in haematological values between the infected and uninfected crocodiles. The values reported here will be useful in diagnostic investigations in both zoo and farmed Nile crocodiles.

    AIDS associated malignancies (ARL) is a major complication associated with AIDS patients upon immunosuppression.Chronically immunocompromised patients have a markedly increased risk of developing lymphoproliferative disease. In the era of potent antiretrovirals therapy (ARV), the malignant complications due to HIV- 1 infection have decreased in developed nations where ARV is administered, but still poses a major problem in developing countries where HIV- 1incidence is high and ARV is still not yet widely available. Even in ARV treated individuals there is a concern that the prolonged survival of many HIV- 1 carriers is likely to eventually result in an increased number of malignancies diagnosed.Malignancies that were found to have high incidence in HIV-infected individuals are Kaposi's sarcoma (KS), Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). The incidence of NHL has increased nearly 200 fold in HIV-positive patients, and accounts for a greater percentage of AIDS defining illness in the US and Europe since the advent of HAART therapy. These AIDS related lymphomas are distinct from their counterparts seen in HIV- 1 seronegative patients.For example nearly half of all cases of ARL are associated with the presence of a gamma herpesvirus, Epstein Barr virus (EBV) or human herpesvirus-8 (HHV-8)/Kaposi's sarcoma associated herpesvirus (KSHV). The pathogenesis of ARLs is complex. B-cell proliferation driven by chronic antigenemia resulting in the induction of polyclonal and ultimately monoclonal lymphoproliferation may occur in the setting of severe immunosuppression.

    Full Text Available Malignant gliomas (MG are the most common type of primary malignant brain tumor. Most patients diagnosed with glioblastoma (GBM, the most common and malignant glial tumor, die within 12-15 months. Moreover, conventional treatment, which includes surgery followed by radiation and chemotherapy, can be highly toxic by causing nonspecific damage to healthy brain and other tissues. The shortcomings of standard-of-care have thus created a stimulus for the development of novel therapies that can target central nervous system (CNS-based tumors specifically and efficiently, while minimizing off-target collateral damage to normal brain. Immunotherapy represents an investigational avenue with the promise of meeting this need, already having demonstrated its potential against B-cell malignancy and solid tumors in clinical trials. T-cell engineering with tumor-specific chimeric antigen receptors (CARs is one proven approach that aims to redirect autologous patient T-cells to sites of tumor. This platform has evolved dramatically over the past two decades to include an improved construct design, and these modern CARs have only recently been translated into the clinic for brain tumors. We review here emerging immunotherapeutic platforms for the treatment of MG, focusing on the development and application of a CAR-based strategy against GBM.

    Full Text Available Based on a review of the literature, reference intervals for water buffalo (Bubalus bubalis serum biochemistry and haematology have not previously been published. The current study was done to establish reference intervals for water buffalo heifers. The International Federation of Clinical Chemistry stated that at least 120 values are necessary to obtain reliable estimates for reference intervals. A total number of 127 clinically healthy buffalo heifers (1–2 years old were included in the study. Animals were examined at buffalo farms that belong to Assiut Governorate, Egypt. Three types of samples were collected: serum samples for biochemical analysis, whole blood samples for haematological analysis and faecal samples for parasitological examination. Animals that fitted the inclusion criteria were included in the study. Biochemical analysis included serum total proteins, albumin, total globulins, alpha, beta and gamma globulin levels, and aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase, creatine phosphokinase and lactate dehydrogenase activity. In addition to the above, serum creatinine, urea, total bilirubin, direct bilirubin, indirect bilirubin, sodium, potassium, chloride, magnesium, calcium, phosphorus, copper, zinc, iron, triglycerides, high density lipoprotein, low density lipoprotein, very low density lipoprotein, glucose levels and 20 haematological variables were measured. The 95.0% reference intervals were calculated by removing the upper and lower 2.5% of the interval for each serum biochemical constituent to give the 2.5 and 97.5 percentiles. Confidence intervals were calculated for each reference limit. Reference intervals from the current study were compared with established values for cows. The current study is as far as could be determined the first that establishes reference intervals for the serum biochemical and haematological parameters in water buffalo heifers.

    This study investigated the factors associated with utilization of fertility preservation and the differences in treatments and outcomes by prior chemotherapy exposure in patients with haematological diseases. This study included all 67 women with haematological diseases seen for fertility preservation consultation at two university hospitals between 2006 and 2011. Of the total, 49% had lymphoma, 33% had leukaemia, 7% had myelodysplastic syndrome and 4% had aplastic anaemia; 46% had prior chemotherapy; and 33% were planning for bone marrow transplantation, 33% pursued ovarian stimulation and 7% used ovarian tissue banking; and 48% of patients did not pursue fertility preservation treatment. All five cycle cancellations were in the post-chemotherapy group: three patients with leukaemia and two with lymphoma. Patients with prior chemotherapy had lower baseline antral follicle count (10 versus 22) and received more gonadotrophins to achieve similar peak oestradiol concentrations, with no difference in oocyte yield (10.5 versus 10) after adjustment for age. Embryo yield was similar between those who had prior chemotherapy and those who had not. Half of the patients with haematological diseases who present for fertility preservation have been exposed to chemotherapy. While ovarian reserve is likely impaired in this group, oocyte yield may be acceptable.

    Full Text Available BACKGROUND Chronic kidney disease (CKD is a major public health problem causing significant morbidity and mortality worldwide. Diabetes mellitus (DM and hypertension are common causes and anaemia is a common complication. It is important to identify the cause and complication, to treat it and prevent its progression to end-stage renal disease (ESRD. AIM To identify the haematological pattern in chronic kidney disease patients and to study the clinical presentation. MATERIALS AND METHODS 72 cases of CKD were studied for a period of 6 months and thorough assessment of clinical features and haematological examinations were done. RESULTS CKD is observed in all age groups and predominantly in older age group greater than 50 yrs., with male preponderance. DM and hypertension are common causes. 89% of the patients presented with anaemia and 4 cases of sickle cell anaemia were observed. Neutrophilic leucocytosis was seen in 29.2% and thrombocytopenia in 8.3% of cases. CONCLUSION CKD is seen in all age groups with a male predominance, common in older age group, anaemia being the most common and important haematological complication. Few cases of sickle cell anaemia (SCA were seen presenting with CKD. Knowledge and treatment of these conditions has proved to improve the quality of life.

    In recent ecotoxicological research, there is an increasing concern about alkylphenolic industrial chemicals, such as nonylphenol (NP), because of their estrogenic properties. Data on the general fish toxicity of these wide spread aquatic pollutants are scarce. In order to evaluate sublethal toxic effects of environmentally relevant concentrations of NP, juvenile Common carp (Cyprinus carpio) were exposed to NP concentrations ranging from 1 to 15 microg NP/l over a 70-day period. Classical toxicological endpoints, such as various haematological parameters and histopathological alterations were investigated. In a comprehensive protocol, besides NP-induced effects also alterations due to a treatment with the synthetic estrogen ethinylestradiol (EE2) were evaluated. After both the NP-exposure as well as the EE2-treatment, the predominant haematological finding was a severe anaemia. Histopathological alterations in the kidney, the liver and the spleen occurred exclusively after treatment with EE2, whereas NP-exposed fish did not show any tissue lesions. Depending on the haematological parameter examined, a NOEC between 1 and 5 microg NP/l could be established. From the present findings, it is assumed, that under field conditions, the NP-induced, general toxic effects, might outbalance the relatively weak estrogenic effects of this compound and possibly might disturb ecologically relevant processes such as fish reproduction.

    Objective: To find out if Gasoline vapour has some effects on haematological indices when inhaled by experimental rats. Methods: The standard method for laboratory operating procedure recommended by World Health Organization was used in all the analysis done. Forty two albino Wistar rats comprising twenty one males (160–220 g) and twenty one females (140–190 g) were sampled into six groups consisting of four test groups and two control groups. The test groups were exposed to gasoline vapour for twenty one days. Test group one were exposed to gasoline for 30 min while test group two were exposed to gasoline vapour for 1 h daily. At the end of twenty one days of exposure, blood samples were collected from the rats and their haematological parameters were estimated. Statistical analysis was done using windows SPSS version 16. Results: The results showed a significant decrease (P Conclusions: The results obtained suggest that inhalation exposure to gasoline may result in pancytopaenia and a significant fluctuation in the red blood cell-dependent haematological indices.

    There are few publications on the clinical haematology and biochemistry of African penguins (Spheniscus demersus) and these are based on captive populations. Baseline haematology and serum biochemistry parameters were analysed from 108 blood samples from wild, adult African penguins. Samples were collected from the breeding range of the African penguin in South Africa and the results were compared between breeding region and sex. The haematological parameters that were measured were: haematocrit, haemoglobin, red cell count and white cell count. The biochemical parameters that were measured were: sodium, potassium, chloride, calcium, inorganic phosphate, creatinine, cholesterol, serum glucose, uric acid, bile acid, total serum protein, albumin, aspartate transaminase and creatine kinase. All samples were serologically negative for selected avian diseases and no blood parasites were detected. No haemolysis was present in any of the analysed samples. Male African penguins were larger and heavier than females, with higher haematocrit, haemoglobin and red cell count values, but lower calcium and phosphate values. African penguins in the Eastern Cape were heavier than those in the Western Cape, with lower white cell count and globulin values and a higher albumin/globulin ratio, possibly indicating that birds are in a poorer condition in the Western Cape. Results were also compared between multiple penguin species and with African penguins in captivity. These values for healthy, wild, adult penguins can be used for future health and disease assessments.

    Full Text Available In the present study, 20 buffaloes suffering from genital prolapse and 10 normal pregnant (control group buffaloes were used to investigate clinical and haematological changes and serum macro mineral contents. Blood samples of all animals were collected aseptically in two portions i.e. with and without anticoagulant. Haematological parameters were determined from samples containing anticoagulant. Serum was separated from the other portion for determination of calcium, phosphorus and magnesium concentrations with spectrophotmetric kits. The results showed that there was a drastic decrease in serum calcium (6.42 ± 1.05 v 10.96 ± 0.95 mg/dl, phosphorus (2.90 ± 0.85 v 5.50 ± 1.61 mg/dl and magnesium (1.50 ± 0.53 v 2.40 ± 0.53 mg/dl levels in prolapsed animals as compared to the controls (P<0.01. There was also a significant decrease in PCV, Hb concentration, lymphocytes and monocytes, while an increase in ESR, WBC counts and neutrophils was observed in prolapsed animals as compared to controls. However, there was no difference in haematological and serum macro mineral contents between vaginal prolapsed and uterine prolapsed buffaloes. It was concluded that deficiency of calcium, phosphorus or magnesium might be possible causes of genital prolapse in these buffaloes.

    Full Text Available There are few publications on the clinical haematology and biochemistry of African penguins (Spheniscus demersus and these are based on captive populations. Baseline haematology and serum biochemistry parameters were analysed from 108 blood samples from wild, adult African penguins. Samples were collected from the breeding range of the African penguin in South Africa and the results were compared between breeding region and sex. The haematological parameters that were measured were: haematocrit, haemoglobin, red cell count and white cell count. The biochemical parameters that were measured were: sodium, potassium, chloride, calcium, inorganic phosphate, creatinine, cholesterol, serum glucose, uric acid, bile acid, total serum protein, albumin, aspartate transaminase and creatine kinase. All samples were serologically negative for selected avian diseases and no blood parasites were detected. No haemolysis was present in any of the analysed samples. Male African penguins were larger and heavier than females, with higher haematocrit, haemoglobin and red cell count values, but lower calcium and phosphate values. African penguins in the Eastern Cape were heavier than those in the Western Cape, with lower white cell count and globulin values and a higher albumin/globulin ratio, possibly indicating that birds are in a poorer condition in the Western Cape. Results were also compared between multiple penguin species and with African penguins in captivity. These values for healthy, wild, adult penguins can be used for future health and disease assessments.

    Full Text Available The development of selected haematological and biochemical parameters during the laying period was monitored in common pheasant hens housed in an enhanced cage system. The cages were enhanced by the addition of two perches and a shelter formed by strips of cloth hanging in the corner of the cage. The results showed significant changes in the haematological and biochemical parameters monitored during egg laying. At the time when laying capacity approached a maximum, a decrease was observed (P<0.05 in haematocrit, erythrocytes, and haemoglobin values, whereas monocytes, eosinophils, the heterophil/lymphocyte ratio, phosphorus, and calcium exhibited an increase (P<0.05. At the end of the laying period, an increase (P<0.05 was recorded in the count of leukocytes, heterophils, lymphocytes and basophils, the heterophil to lymphocyte ratio, and the concentrations of aspartate aminotransferase, cholesterol, phosphorus, and calcium, whereas lower values (P<0.05 were recorded for haematocrit and plasma total protein in comparison with the values of the indicators at the beginning of the laying period. The results provide new information about dynamic changes in selected haematological and biochemical parameters in clinically healthy common pheasant hens during the laying period.

    Full Text Available Paediatric patients with cancer are a high-risk patient population for medication misadventures. This study aimed to document and evaluate the role of pharmacists’ interventions during dispensing-related activities in minimising the occurrence of medication misadventure in haematology-oncology patients. The primary investigator observed and documented all clinical interventions during dispensing-related activities performed by clinical pharmacists in a haematology-oncology pharmacy during 33-day. A total of 359 interventions were performed for 1028 patients. The rates of intervention were 20.04 per 100 medication orders and 34.92 per 100 patients. Provision of drug information was the most common interventions constituting more than three quarters of all interventions. According to therapeutic groups, cytotoxic antineoplastics made up more than half of all interventions. Of all interventions, 22 involved recommendations leading to changes in patients’ treatment (active interventions, and all recommendations were accepted. The top three medication errors were due to inappropriate dosing, labelling error, and unfulfilled indication. Clinical pharmacists’ intervention during dispensing in a paediatric haematology-oncology pharmacy improved medication safety and patient care by minimising the incidence of medication misadventures.

    Trichlorfon is among the most commonly used products to treat fish parasites in aquaculture. We investigated the effectiveness of propolis in alleviating the toxicity of trichlorfon on haematological and oxidant/antioxidant parameters in carp Cyprinus carpio. Fish were exposed to sublethal concentrations (11 and 22 mg l-1) of trichlorfon, and propolis (10 mg kg-1 of fish weight) was simultaneously administered. At the end of 14 d administration, blood and tissue (liver, kidney, gill) samples were collected. Haematological changes (red and white blood cell count, haemoglobin concentration, haematocrit level and erythrocyte indices: mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration) were determined in the blood samples, while antioxidant parameters (malondialdehyde and reduced glutathione levels and superoxide dismutase, catalase and glutathione peroxidase activities) were evaluated in the liver, kidney and gill samples. Trichlorfon led to negative alterations in the haematological and antioxidant parameters investigated. The administration of propolis alleviated this effect and suggests that fish treated with trichlorfon improve their physiological status when fed a propolis-supplemented diet.

    Full Text Available The course and outcome of a disease process is dependent upon factors such as the disease-causing agent and its cell tropism, defense mechanisms of the host, genetic resistance of the species or breed affected, as well as the age, nutritional status and hormonal levels of the affected animal. When haematology, clinical biochemistry and cytology test results are combined with other laboratory procedures, complete physical examination and also with the history of the patient, a veterinarian is well armed to arrive at a definitive diagnosis, make a certain prognosis (good, poor or guarded and can also make a concluding statement on the efficacy of the instituted therapy. In clinical biochemistry, demonstration of specific enzyme activity and concentration of analytes in serum/plasma facilitates the disease diagnosis. Also, evaluation of haematology, clinical biochemistry and diagnostic cytology tests can help establish the presence or absence of diseases of internal organs, and by serial performance of these tests, may help to determine whether a disease process remains static, progressive or regressive. This review therefore provides the haematological, serum biochemical and cytological characteristics of diseases caused by the main bacteria, viruses, fungi, protozoa, helminths, arthropods, nutritional deficiencies, endocrine disturbances, neoplasm, allergy, toxins (phytoxins and zootoxins and inorganic poisons in horses.

    Full Text Available Munchausen syndrome are characterized by physical or psychological symptoms that are intentionally produced or feigned in order to assume the sick role. The judgment that a particular symptom is intentionally produced is made both by direct evidence and by excluding other causes of the symptom. This disorder frequently cooccurs with significant personality or relational disorders. Primal motivation of these patients is to get hospitalized and this is almost a life style for them. Hematologic complaints are very common among who admit to hospitals.In this report a patient who admitted to Baskent University, Adana Teaching and Medical Research Center, hematology outpatient clinic and diagnosed as Munchausen syndrome is reported.

    In this article, we study the possibility of sustaining static and spherically symmetric traversable wormhole geometries admitting conformal motion in Einstein gravity, which presents a more systematic approach to search a relation between matter and geometry. In wormhole physics, the presence of exotic matter is a fundamental ingredient and we show that this exotic source can be dark energy type which support the existence of wormhole spacetimes. In this work we model a wormhole supported by dark energy which admits conformal motion. We also discuss the possibility of the detection of wormholes in the outer regions of galactic halos by means of gravitational lensing. Studies of the total gravitational energy for the exotic matter inside a static wormhole configuration are also performed.

    Albuquerque, Helena; Barreiro, Elisabete; Calderón Martín, Antonio J.; Sánchez Delgado, José M.

    2016-12-01

    In the literature, most of the descriptions of different classes of Leibniz superalgebras (L =L0bar ⊕L1bar , [ ṡ , ṡ ]) have been made by giving the multiplication table on the elements of a graded basis B ={vk } k ∈ K of L, in such a way that for any i , j ∈ K we have [vi ,vj ] =λi,j [vj ,vi ] ∈ Fvk for some k ∈ K, where F denotes the base field and λi,j ∈ F. In order to give a unifying viewpoint of all these classes of algebras we introduce the category of Leibniz superalgebras admitting a multiplicative basis and study its structure. We show that if a Leibniz superalgebra L =L0bar ⊕L1bar admits a multiplicative basis then it is the direct sum L =⨁αIα with any Iα =I α , 0 bar ⊕I α , 1 bar being a well described ideal of L admitting a multiplicative basis inherited from B. Also the B-simplicity of L is characterized in terms of J-connections.

    Hyaluronan, a major macropolysaccharide in the extracellular matrix of connective tissues, is intimately involved in the biology of cancer. Hyaluronan accumulates into the stroma of various human tumors and modulates intracellular signaling pathways, cell proliferation, motility and invasive properties of malignant cells. Experimental and clinicopathological evidence highlights the importance of hyaluronan in tumor growth and metastasis. A high stromal hyaluronan content is associated with poorly differentiated tumors and aggressive clinical behavior in human adenocarcinomas. Instead, the squamous cell carcinomas and malignant melanomas tend to have a reduced hyaluronan content. In addition to the stroma-cancer cell interaction, hyaluronan can influence stromal cell recruitment, tumor angiogenesis and epithelial-mesenchymal transition. Hyaluronan receptors, hyaluronan synthases and hyaluronan degrading enzymes, hyaluronidases, are involved in the modulation of cancer progression, depending on the tumor type. Furthermore, intracellular signaling and angiogenesis are affected by the degradation products of hyaluronan. Hyaluronan has also therapeutic implications since it is involved in multidrug resistance.

    The management of recurrent, symptomatic malignant ascites can be problematic for physicians and patients. The most common, low-risk method is large-volume paracentesis. Patient disease progression often leads to rapid reaccumulation of ascites, which requires frequent return visits to the hospital for symptom management. Other techniques have been developed to achieve palliation of symptoms, including tunneled external drainage catheters, peritoneal ports, and peritoneovenous

    Full Text Available Malignant catatonia is an unusual and highly fatal neuropsychiatric condition which can present with clinical and biochemical manifestations similar to those of pheochromocytoma. Differentiating between the two diseases is essential as management options greatly diverge. We describe a case of malignant catatonia in a 20-year-old male who presented with concurrent psychotic symptoms and autonomic instability, with markedly increased 24-hour urinary levels of norepinephrine at 1752 nmol/day (normal, 89–470 nmol/day, epinephrine at 1045 nmol/day (normal, <160 nmol/day, and dopamine at 7.9 μmol/day (normal, 0.4–3.3 μmol/day. The patient was treated with multiple sessions of electroconvulsive therapy, which led to complete clinical resolution. Repeat urine collections within weeks of this presenting event revealed normalization or near normalization of his catecholamine and metanephrine levels. Malignant catatonia should be considered in the differential diagnosis of the hypercatecholamine state, particularly in a patient who also exhibits concurrent catatonic features.

    Twenty gastrointestinal lipomata in 18 patients are reviewed: 15 located in the colon, 3 in the distal ileum, one in the duodenum, and one in the stomach. They were found most frequently in European-born, elderly women and presented with variable abdominal symptomatology. Four lipomata were removed during endoscopy, the remainder at laparotomy, partial colectomy being performed in 10 cases. All, except 2 subserosal types, were located in the submucosa, and their average size was 2.7 cm diameter. Microscopically, none showed true encapsulation, and all were composed of mature fat cells without cellular atypia. In spite of nonspecific changes at endoscopy, one-half of the cases showed, on microscopic examination, atrophy of the overlying glands and a prominent eosinophilic and/or lymphoplasmocytic infiltration of the lamina propria. Two large subserosal lipomata were associated with Crohn's disease. In addition, in 39% of cases, malignant tumours, either single or double, were present in the gastrointestinal tract or elsewhere. Gastrointestinal "lipomata" are located in the sites of normal fatty infiltration in the elderly; these growths could be a local aging or reactive process of the intestinal wall rather than true neoplasms without any potential malignancy. However, coexistent malignancies should be carefully searched for in elderly patients with colonic lipoma.

    Full Text Available Neuroleptic malignant syndrome (NMS is a rare but potentially fatal disease characterized by fever, muscle rigidity, delirium and autonomic instability. Here we report a child, with NMS due to the risperidone misdiagnosed as status epilepticus. Nine year old boy, who had been under high dose risperidone treatment for 8 weeks, admitted to the emergency room because of the contractions (evaluated as status epilepticus persisting for 7 hours. Since there was neuroleptic treatment in the past medical history and, unconsciousness, muscular rigidity, diaphoresis, hypertermi and, hypotension in physical examination, leucocytosis and elevated creatininphosphokinase levels in laboratory tests, the patient was evaluated as NMS and discharged without any complications. We reported this case to point out that; NMS may be misdiagnosed as status epilepticus in children when EEG monitoring is unavailable. When a child admitted to the emergency room because of suspicious convulsion neuroleptic drug use must surely be asked.

    Assessment of the prognostic indicators of wildlife casualties is critical in wildlife rehabilitation practice, to optimize the use of economical resources, and to protect animal welfare. Few studies have been conducted in this field. To identify the prognostic indicators associated with raptor mortality during the first week of hospitalization. Complete medical records of 1722 wild raptor cases admitted to a wildlife rehabilitation centre from 1995 to 2007 were used. Regression models were created to determine mortality-related factors for different variables (order, sex, body condition (BC), clinical signs, and available haematological and biochemical parameters). In the bivariate analysis, the presence of nervous (OR = 11.9, 95%CI:5.1-27.6) or musculoskeletal (OR = 12.1, 95%CI:5.8-25.3) signs, a poor BC (OR = 32.9, 95%CI:19-81.2), and low values of packed cell volume (PCV), haemoglobin or total solids (TS), were all associated with early mortality. After adjusting variables in the multivariate model, BC was excluded due to co-linearity with other variables, and alteration of the nervous system was the only significant risk factor (OR = 4.0; 95%CI:1.9-8.8). In species specific analysis, poor prognosis was related to neurological signs in Athene noctua, poor BC in Strix aluco, trauma in Acciptiter nisus and Tyto alba, low PCV in Buteo buteo and Falco tinnunculus and low TS in Falco tinnunculus. Raptors with a poor BC, low values of PCV and those presenting with neurological signs, had the highest risk of dying in the first days of admittance. Thus, either medical care or humane euthanasia for poor prognosis should be performed to address animal welfare.

    The posaconazole extended release tablet formulation was developed to improve bioavailability relative to the oral suspension. Therapeutic drug monitoring has been used to optimise posaconazole dosing to achieve a target trough level ≥0.7 μg ml(-1). We retrospectively evaluated 28 patients with haematological malignancies who received posaconazole tablets for antifungal prophylaxis. Posaconazole serum trough levels were obtained 5 days after initiation of therapy. Mean trough level was 1.19 ± 0.63 μg ml(-1), and 71% achieved a trough level ≥0.7 μg ml(-1). Diarrhoea was associated with lower mean trough levels (0.65 ± 0.08 μg ml(-1) vs. 1.31 ± 0.13 μg ml(-1)), P = 0.002. Mean trough levels were lower in patients ≥90 kg (0.74 ± 0.09 μg ml(-1)) vs. Posaconazole delayed release tablets attain appropriate trough levels in most patients, but patients with a higher weight and those experiencing diarrhoea are more likely to have lower levels.

    of 9156 first admitted schizophrenic patients. Suicide accounted for 50% of deaths in men and 35% of deaths in women. Suicide risk was particularly increased during the first year of follow-up. Death from natural causes, with the exception of cancer and cerebrovascular diseases, was increased. Suicide...... risk during the first year of follow-up increased by 56%, with a 50% reduction on psychiatric in-patient facilities. The study confirms that mortality in schizophrenia is still markedly elevated, and the finding of an increasing suicide risk may be an indicator of some adverse effects...

    Full Text Available A 60-year-old man with a history of bipolar disorder on risperidone, bupropion, and escitalopram was admitted for community acquired streptococcal pneumonia. Four days later, he developed persistent hyperthermia, dysautonomia, rigidity, hyporeflexia, and marked elevation of serum creatine phosphokinase. He was diagnosed with neuroleptic malignant syndrome (NMS and improved with dantrolene, bromocriptine, and supportive therapy. This case emphasizes the importance of considering a broad differential diagnosis for fever in the ICU, carefully reviewing the medication list for all patients, and considering NMS in patients with fever and rigidity.

    Full Text Available Although it is generally accepted that a malignant transient pleural transudate may appear during the early stages of lymphatic obstruction, cases demonstrating such probability are rare in literature. A 67-year-old woman was admitted to hospital because a lymphangitic carcinomatosis and a transudative infrapulmonary pleural effusion with a cytology positive for adenocarcinoma. One month later the effusion keeps being positive for adenocarcinoma but exudative in character. Lymphatic obstruction appears as the cause of the initial transudative characteristics of the pleural effusion.

    Full Text Available Malignant otitis externa (MOE is a severe infection of external auditory canal and skull base. A 17-year-old diabetic girl was admitted with diabetic ketoacidosis. Cellulitis of her right ear occurred on the second day of hospitalization and a black necrotic scar in the same region appeared on the next day. The lesion rapidly invaded to right side of neck and surrounding tissue of the patient. Therefore, antimycotic therapy was started. Unfortunately the patient died on seventh day of hospitalization because of probably extensive fungal invasion. Physicians should suspect MOE connected to mucormycosis especially in patients with cutaneous lesions of ear unresponsive to antibiotic therapy.

    A 37-year-old man was admitted to our hospital for an evaluation of renal dysfunction and hypertension. The C-reactive protein level was 6.0 mg/dL, and the serum renin activity was extremely high. A renal biopsy showed malignant nephrosclerosis-like lesions with an onion skin pattern. He had a history of recurrent abdominal pain associated with periodic fevers above 38 degrees that resolved within three days. A MEditerranean FeVer (MEFV) gene analysis revealed that he was homozygous for the E148Q polymorphism (exon 2) and heterozygous for the L110P polymorphism (exon 2). The present case demonstrates that persistent subclinical inflammation can lead to malignant nephrosclerosis in familial Mediterranean fever patients with this genotype.

    Malignant adnexal carcinomas of the skin are rare but associated with high propensity for local recurrence, and for some of the distinct subgroups they are known to metastasize regionally or distant. Biopsy is necessary for correct diagnosis, as the lesions cannot be separated from other tumour...... types entirely on their clinical appearance. The histologic diagnosis is troublesome, and the lesions are often mistaken for their benign counterpart, basal cell carcinoma or squamous cell carcinoma. The lesions are treated with surgery.

    Full Text Available The ceruloplasmin concentration was determined in 145 cancer patients prior to and after treatment with different radiotherapeutic and chemotherapeutic regimes. The ceruloplasmin concentration was observed to be higher in patients with malignancies than in healthy controls. There was a positive correlation of the values with the clinical condition of the patients. The ceruloplasmin concentration was noted to stop increasing and subsequently fall in patients who responded to therapy, and, in contrast, to remain high or become higher in those who did not respond to therapy. The diagnostic and prognostic value of ceruloplasmin determination is discussed.

    We investigated whether 12 months of chronic endurance training would affect haematology, CD4(+) lymphocyte transferrin receptor (CD71) expression, CD4(+) intracellular iron and the incidence of upper respiratory tract illnesses (URTI) in Ironman triathletes compared with untrained men. Resting venous blood samples were taken from 15 Ironman triathletes (TR 30 ± 5 year) and 12 untrained men (UT 30 ± 6 year) every 4 weeks for 12 months. Erythrocyte, leukocyte and platelet concentration, haematocrit, haemoglobin (Hb) and mean corpuscular haemoglobin (MCHC) were measured with a full blood count. CD4(+) lymphocytes were analysed for changes in transferrin receptor (CD71) expression (CD4(+)CD71(+)), and intracellular iron (Fe(3+)), by flow cytometry. The TR group had significantly lower Hb, MCHC, and platelets for 10, 9 and 11 months, respectively; lower CD4(+)CD71(+) (3 months) and Fe(3+) (1 month), respectively; higher CD4(+)CD71(+) (1 month); a higher lymphocyte count for 4 months. There were no between-group differences in other variables. In both groups haematology and lymphocytes increased during spring, early summer and winter and decreased during late summer/late winter, with an inverse relationship between CD4(+)CD71(+) and Fe(3+). The TR group reported significantly fewer URTI than the UT. Low Hb and MCHC suggest an iron deficiency which may affect triathlete performance. Monthly changes in lymphocytes, CD4(+)CD71(+) and Fe(3+) suggested that spring, summer and late autumn are associated with CD4(+) proliferation. There may be seasonal relationships between haematology and lymphocyte function, independent of endurance training, possibly affecting performance but not the incidence of URTI.

    Full Text Available The effect of dietary feed additives on haematological and serum biochemical parameters of broiler chickens was evaluated. 180 day-old Arbor acre broiler chicks were weighed and randomly allotted to five dietary treatments with 3 replicates of 12 birds each. Broiler starter diet (2855.7 kcal/kg ME; 23.01% and finisher diet (2911 kcal/kg; 20.71% CP were formulated. Dietary treatments were control diet (basal diet without additives, OXYT diet (basal diet with oxytetracycline at 600 ppm as antibiotic, GRO-UP diet (basal diet with probiotic at 500 ppm, MOS-500 diet (basal diet with mannan oligosaccharide at 500 ppm and MOS-1000 diet (basal diet with mannan oligosaccharide at 1000 ppm. Feed and water were supplied ad libitum. At the end of weeks 4 and 8, blood samples were collected and analyzed. The haematological and serum biochemical parameters of broiler chickens fed diets containing feed additives at the starter phase were not statistically significant (P> 0.05. At the finisher phase, there were no significant (P> 0.05 differences in all the parameters measured except in the heterophils and eosinophils where birds fed the control diets had the lowest value among all treatments. Serum globulin values were significantly (P< 0.05 different as birds fed diets containing OXYT (antibiotics recorded the lowest value among all treatments. The inclusion of prebiotics and probiotics in the diets of broiler chickens elicited no adverse effect on haematological and serum biochemical parameters, thus, they can be used as replacement for antibiotics.

    Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. Sufficient calcium intake has been reported to support bone growth and prevent bone loss during the ageing process. To determine the effect of Lactobacillus helveticus MTCC 5463 probiotic dietary intervention on serum calcium & haematological parameters in geriatric population. Healthy volunteers with age ranging from 64-74 years were recruited from the nearby residential areas in and around Anand, Gujarat. Study duration was from 2012 to 2015. Of the 112 subjects initially enrolled in the trial, 36 withdrew before the intervention because of not matching with criterias. Of the 76 participants, 5 subjects (4%) under test group and 12 subjects (11%) under placebo left the study. We had 59 subjects who successfully completed a double blind cross over trial. Probiotic fermented milk products (in form of "Lassi") was prepared by supplementing toned milk with honey and fermenting with probiotic Lactobacillus helveticus MTCC 5463 and Streptococcus thermophilus MTCC 5460. The final product had at least 10(8) CFU/ml of viable Lactobacillus helveticus MTCC 5463 at the time of feeding. During feeding period, 200 ml of fermented product containing the test strain to one group and a similar product but without the test strain as placebo were fed regularly at the time of breakfast in morning for 4 weeks. Subjects of each group were given a washout period of 4 weeks before they were crossed over and included to the other group. The study was approved by institutional ethics committee. The socio-demographic and clinical profiles were similar at baseline. The mean (SD) calcium level improved significantly in test {9.36 (0.45) vs 8.45 (0.61), p<0.001}. No significant effect was observed with respect to haemoglobin & haematological parameters. The well-documented probiotic Lactobacillus helveticus MTCC 5463 confirmed increase in serum calcium level but no effect on

    Selenium depletion has been reported in critical illness correlates with an increase in mortality and morbidity. In this study, we aimed to access the selenium plasma levels of septic patients early at the Intensive Care Unit (ICU) admission in order to compare with reference range. We conducted a cross-sectional study in a university affiliated hospital aiming to assess the early plasma level of selenium in ICU admitted patients. eighty patients diagnoses with sepsis were included and considered for characteristic evaluation, monitoring criteria assessment and also blood sampling. All blood sampling was performed during 48 hours of the ICU admission in order to determined the plasma Selenium level by atomic absorption method. The mean plasma levels of selenium in male and female was 98.14 ± 23.52 and 78.1 ± 24.46 μ/L, respectively. Although selenium plasma levels was higher in the ICU male patients significantly, both had near normal range (80 μ/L). In this study we found that in early admitted Iranian ICU patients in Tehran, selenium deficiency has not routinely seen but probably will happen during ICU hospitalization.

    This study was conducted in 16 healthy immature dromedary camels weighing 120-150 kg to evaluate and compare the effects of epidural and intramuscular injections of xylazine administered at 0.1 mg/kg and 0.2 mg/kg. Haematological parameters included haemoglobin, packed cell volume, total erythrocyte count and total leukocyte count. Biochemical parameters included alkaline phosphates, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and glucose. Parameters were measured at different intervals before (baseline) and after the administration of drugs. Our study showed that the effect of xylazine on haematological and biochemical parameters is dose-dependant and is also related to the route of administration. The low dose of xylazine administered using both intramuscular and epidural methods showed minimal effects, whereas high doses of the drug, especially when injected intramuscularly, caused greater changes in haematological and biochemical parameters.

    This experiment was conducted to determine the effect of aqueous extract of Telfairia occidentalis (Fluted Pumpkin) leaf on the performance and haematological indices of starter broilers. A total of 200, 8-day-old broiler chicks were randomly allotted to five (5) treatments, each with 4 replicate groups containing 10 chicks and fed with standard starter broiler diets. Telfaria occidentalis leaves extract (FPLE) was added at 0, 40, 80, 120, and 160 mL/litre of drinking water. Growth performance and haematological indices were evaluated. Results showed that there was significant (P 0.05) variations in the feed and water intakes of the birds. Results also show no significant (P > 0.05) difference in haematological indices of birds among the treatments. The results of this study indicate that, for enhanced weight gain and feed conversion efficiency, birds should be fed 80 mL FPLE/litre of water. PMID:23738128

    Introduction. Uterine leiomyoma is the most common benign pathology in women and lipoleiomyoma is an extremely rare and specific type of leiomyoma. Here, we report an unusual case of giant pedunculated subserous lipoleiomyoma misdiagnosed preoperatively as leiomyosarcoma. Case. A 45-year-old woman admitted to our gynecology outpatient clinic for complaints of abdominal distention, tiredness, and pelvic pain for the last 6 months. Sonography and abdominal magnetic resonance imaging (MRI) showed a giant semisolid mass that filled whole abdominal cavity from pelvis to subdiaphragmatic area. A primary diagnosis of uterine sarcoma or ovarian malignancy was made. On operation, total abdominal hysterectomy with a pedunculated mass of size 30 × 23 × 12 cm and weighing 5.4 kg and bilateral salpingo-oophorectomy were performed. The histopathology revealed a lipoleiomyoma with extensive cystic and fatty degeneration without any malignancy. Discussion. The diagnosis of leiomyoma is done usually with pelvic ultrasound but sometimes it is difficult to reach a correct diagnosis especially in cases of giant and pedunculated lipoleiomyoma that included fatty tissue which may mimick malignancy. Conclusion. Subserous pedunculated giant lipoleiomyoma should be kept in mind in the differential diagnosis of leiomyosarcoma or ovarian malignancy.

    Full Text Available Malignant mesothelioma is a disease that originates from mesenchymal cells. It is related to the occupational or environmental exposure to asbestos. The treatment remains controversial because it is commonly diagnosed at a very late stage, and the prognosis is very poor. In this report, we present a 37-year-old female patient who was admitted with shortness of breath, palpitation and inability to sleep on her back for the previous 10 days. A large pericardial effusion was detected on echocardiography. Pericardiocentesis was performed and the patient’s symptoms were alleviated. However, approximately 7 months later, she was readmitted to the clinic with complaints of a mass at the incision site. Pathological examination of the mass yielded a diagnosis of pericardial malignant mesothelioma. Malignant mesothelioma is a rare occurrence, and to our knowledge, there are no reports in the English literature of pericardial malignant mesothelioma local invasion to an incision site.

The median ­survival of newly diagnosed GBM patients was between 9 to 12 months prior to treatment with ­temozolomide being introduced. Primary resection that is as complete as possible is recommended for malignant glioma. Conventional fractionated irradiation 55 to 60 gy with concomitant temozolomide followed by standard temozolomide 6 cycles (5/28 (EORTC/NCIC-regime published by R Stupp in 2005 is the standard of care for newly diagnosed GBM after surgery, independent of the methylation status of the MGM-T gene promoter. Age is no ­contraindication for treatment with temozolomide, although comorbidity and performance status have to be ­considered. For temozolomide naive GBM and astrocytoma grade III patients with disease progression, temozolomide is still the treatment of choice outside of clinical studies. A ­general consensus regarding the schedule of choice has not yet been achieved; so far the 5 out of 28 days regimen (5/28 is the standard of care in most countries. Patients with disease progression after standard temozolomide (5/28 are candidates for clinical studies. Outside of clinical ­studies, dose-dense (7/7, prolonged (21/28, or metronomic (28/28 temozolomide, or alternatively a nitrosourea-based regimen can be an option. The excellent toxicity profile of ­temozolomide allows for various combinations with antitumor agents. None of these ­combinations, however, have been demonstrated to be statistically significantly superior compared to temozolomide alone. The role of lower dosed, dose-dense, or continuous regimen with or without drug combination and the role of temozolomide for newly diagnosed astrocytoma grade III and low grade glioma still has to be determined.Keywords: glioblastoma

    Full Text Available Abstract Background Haematological traits, which consist of mainly three components: leukocyte traits, erythrocyte traits and platelet traits, play extremely important role in animal immune function and disease resistance. But knowledge of the genetic background controlling variability of these traits is very limited, especially in swine. Results In the present study, 18 haematological traits (7 leukocyte traits, 7 erythrocyte traits and 4 platelet traits were measured in a pig resource population consisting of 368 purebred piglets of three breeds (Landrace, Large White and Songliao Black Pig, after inoculation with the swine fever vaccine when the pigs were 21 days old. A whole-genome scan of QTL for these traits was performed using 206 microsatellite markers covering all 18 autosomes and the X chromosome. Using variance component analysis based on a linear mixed model and the false discovery rate (FDR test, 35 QTL with FDR FDR FDR Conclusions Very few QTL were previously identified for hematological traits of pigs and never in purebred populations. Most of the QTL detected here, in particular the QTL for the platelet traits, have not been reported before. Our results lay important foundation for identifying the causal genes underlying the hematological trait variations in pigs.

    Full Text Available This prospective longitudinal study investigated the progression of haematological changes in 32 transfused and 54 non-transfused dogs naturally infected with Babesia rossi over the 1st 6 days following diagnosis and treatment. The effect of patient age on the results of complete blood counts was determined. Haematology data were analysed at presentation and at 24 hours, 3 days and 6 days after presentation. Dogs were treated with diminazene aceturate at diagnosis and a blood transfusion was given if deemed clinically required. Mildly to moderately regenerative normocytic normochromic anaemia was observed in all dogs throughout the study period. Transfused dogs more often had an inflammatory leukogram at presentation and at 24 hours, than dogs that were not transfused. In dogs with a left shift, a concurrent normal or decreased segmented neutrophil count was found more commonly than neutrophilia. Severe thrombocytopenia that resolved within a week was common. Blood transfusion alleviated the anaemia, but had no significant effect on white blood cell or platelet responses. Blood cell responses were not significantly influenced by age. In conclusion, the red blood cell and white blood cell responses were less than expected in dogs with babesiosis, given the degree of anaemia and inflammation present. The magnitude of thrombocytopenia and rapid return of the platelet count to normal suggested a possible immune-mediated mechanism for the thrombocytopenia.

    Examinations for heartworm (Dirofilaria immitis) were performed on 175 impounded dogs from a hyperendemic area of the Po Valley (Italy). Each blood sample was used with five haematological diagnostic methods (filtration, direct smear, modified Knott, clotted blood and capillary tube) and three commercial ELISA kits (PetChek, Diasystems, Uni-Tec). The results were compared with the true infection status obtained from post-mortem examination of the heart, pulmonary arteries, thoracic venae cavae and lungs. The prevalence of the infection by adult worms at necropsy was 63%. The sensitivity of the tests ranged from 60% (capillary tube) to 81% (Diasystems) and the specificity from 88% (filtration) to 98% (PetChek). The results of all the tests differed significantly (p < 0.01) from those obtained at necropsy. The sensitivity of the tests was also assessed with respect to the differing numbers of worms in the hosts. A positive correlation between the worm burden and the sensitivity was observed in all the tests. It is apparent that the ELISA methods were better able to detect cases with a low number of worms than the haematological tests.

    Full Text Available Background.\tWhile there is evidence that HIV affects the course and outcome of pregnancy, reports on the effects of pregnancy on HIV infection remain conflicting, especially in low-resource settings. Methodology. A prospective study of two demographically similar cohorts of HIV-seropositive women, 154 pregnant and 151 non-pregnant, was conducted in a hospital setting in Nigeria. Results. Cases and controls were matched for age, but parity in controls was significantly higher than in cases (p<0.0001. The time between diagnosis and treatment commencement was greater in controls compared with cases (p<0.0001. Electrolyte, urea and creatinine levels were within normal limits, with mean serum urea and potassium higher in controls compared with cases (p=0.002 and p=0.023. Aspartate aminotransferase (AAT/serum glutamic oxaloacetic acid transaminase (SGOT, alanine aminotransferase (ALT/serum glutamic-pyruvic transaminase (SGPT and amylase levels were higher in controls compared with cases (p=0.001, p=0.0001 and p=0.05, but the mean CD4 count was higher in cases compared with controls (p=0.001. The haematological parameters were within normal limits and comparable in cases and controls. A comparison of CD4 count, total white blood cell count and packed cell volume across the three trimesters in the cases did not reveal any statistically significant differences in these parameters. Conclusion. Pregnancy did not affect biochemical and haematological parameters in HIV-infected Nigerian women.

    Full Text Available Thirty-two adult riverine buffaloes (Buhalis bubalus in their last trimester of pregnancy were selected and randomly divided into four groups. The buffaloes of group I served as control. Animals in group II, III and IV were treated twice (7 days apart with levamisole hydrochloride (0.5mg/kg b. w. orally, Etosol (Vit E+Se, 10ml, I/m and Bacilli Calmette Guerine (BCG (0.5 ml/animal, s/c, respectively. Blood samples were collected at weekly intervals starting day 0 untill parturition. Total erythrocytic count and packed cell volume values were higher (P<0.05 in levamisole and vit E+Se treated group of buffaloes. Haemoglobin concentration was higher (P<0.05 inVit E+Se treated group. MCV, MCH and MCHC remained unchanged among all the experimental groups. Total leukocyte count was higher (P<0.05 in levamisole treated group of buffaloes. Differential leukocyte counts (relative revealed moderate lymphocytosis in all immunomodulated groups with significantly higher counts in Vit E+Se treated buffaloes. It was inferred that levamisole and vit E-se altered some haematological values, whereas BCG did not affect the haematological parameters.

    Haematological (WBC, RBC, Hgb and Hct) and genotoxicity (MNT) parameters, hepatic enzymatic activities (GST, GPx and GR), and a histopathological evaluation of liver, kidneys and gonads were assessed as general biomarkers of metal pollution in the shrew Crocidura russula inhabiting a pyrite mining area. Specimens exposed to metals presented a few significant alterations when compared with reference animals: GST activity decreased; micronuclei increased; and evident liver alterations related to metal exposure were observed. On the basis of all the parameters studied, age was an important factor that partly explained the observed variation, whereas sex was the least important factor. Significant correlations were also found between heavy metal concentrations and biomarkers evaluated, demonstrating the great influence of these metals in the metabolic alterations. To the best of our knowledge, these data constitute the first measurements of a battery of biomarkers in shrews from a mine site and are among the few available for insectivorous mammals. - Metals from an abandoned pyrite mine produce alterations in haematological parameters, GST, MNT, and histopathology in shrews.

    Full Text Available Introduction: Though nutrition is a key input to blood formation, little is known about the extent maternal dietary quality contributes to the haematological status of pregnant women in Northern Region of Ghana. Objective: The aim of this study was to assess the independent contribution of dietary diversity to haematological status of pregnant women whilst controlling for potential confounding factors including malarial infection. Methods: A cross-sectional study design was used on a sample of 307 pregnant women in their third trimester. A structured questionnaire was used to collect socio-demographic characteristics, obstetric and dietary data related to anaemia. Overall dietary quality was assessed using the dietary diversity score. Haemoglobin concentration (Hb was measured using portable HemoCueR Hb 301 system. Predictors of anaemia were estimated using multiple linear regression analysis. Results: The mean Hb was 10.8±1.4 g/dl and prevalence of anaemia (Hb < 11.0 g/dl was 46.3 %. High dietary diversity score [Beta coefficient (β, = 0.141 p < 0.001], multi-gravidity (β=0.205 and high composite score for ANC content (β= 0.201 were associated with a decreased risk of anaemia in the third trimester of pregnancy. Conclusion: The findings suggest the need to strengthen interventions that focus on improving the consumption of diversified foods particularly during pregnancy.

    The guideline group was selected to be representative of UK-based medical experts. Ovid MEDLINE, EMBASE and NCBI Pubmed were searched systematically for publications in English from 1980 to 2012 using the MeSH subheading 'lymphoma, CNS', 'lymphoma, central nervous system', 'lymphoma, high grade', 'lymphoma, Burkitt's', 'lymphoma, lymphoblastic' and 'lymphoma, diffuse large B cell' as keywords, as well as all subheadings. The writing group produced the draft guideline, which was subsequently revised by consensus by members of the Haemato-oncology Task Force of the British Committee for Standards in Haematology (BCSH). The guideline was then reviewed by a sounding board of ~50 UK haematologists, the BCSH and the British Society for Haematology (BSH) Committee and comments incorporated where appropriate. The 'GRADE' system was used to quote levels and grades of evidence, details of which can be found in Appendix I. The objective of this guideline is to provide healthcare professionals with clear guidance on the optimal prevention of secondary central nervous system (CNS) lymphoma. The guidance may not be appropriate to patients of all lymphoma sub-types and in all cases individual patient circumstances may dictate an alternative approach.

    Full Text Available The haematological alterations produced on exposure of the African snakehead, Parachanna africans to the sublethal concentration (0.0, 0.1, 1.0 and 10.0 mg/L of cadmium (Cd2+ for 21 days have been studied. Red blood cell (RBC count, haemoglobin (Hb concentration, haematocrit (Hct, the mean corpuscular haemoglobin (MCH and the mean corpuscular volume (MCV levels were decreased with an increase in exposure concentration, but the level of the mean corpuscular haemoglobin concentration (MCHC was increased. These alterations could be attributed to haemolysis and impairment of haemoglobin synthesis, resulting in a hypochromic microcytic anaemia, induced by exposure to cadmium. Cadmium exposure also caused significant decreases in white blood cell (WBC count. The primary consequence of the observed changes in total and differential leucocyte counts in stressed fish was attributed to suppression of the immune system and increased susceptibility to disease. Plasma glucose and total plasma protein concentrations were significantly decreased; showing that cadmium affects the fish energy metabolism. The present study thus confirmed that haematological parameters are very sensitive indicators of fish organism response to chemicals in this case cadmium.

    Full Text Available Abstract Background Malaria is the commonest cause of childhood morbidity in Western Kenya with varied heamatological consequences. The t study sought to elucidate the haemotological changes in children infected with malaria and their impact on improved diagnosis and therapy of childhood malaria. Methods Haematological parameters in 961 children, including 523 malaria-infected and 438 non-malaria infected, living in Kisumu West District, an area of malaria holoendemic transmission in Western Kenya were evaluated. Results The following parameters were significantly lower in malaria-infected children; platelets, lymphocytes, eosinophils, red blood cell count and haemoglobin (Hb, while absolute monocyte and neutrophil counts, and mean platelet volume (MPV were higher in comparison to non-malaria infected children. Children with platelet counts of Conclusion Children infected with Plasmodium falciparum malaria exhibited important changes in some haematological parameters with low platelet count and haemoglobin concentration being the two most important predictors of malaria infection in children in our study area. When used in combination with other clinical and microscopy, these parameters could improve malaria diagnosis in sub-patent cases.

    Couples' ability to cope with cancer is significantly associated with how satisfied they are with their relationship. However, little evidence specific to haemato-oncological patients exists. The objective of this study was to examine how dyadic coping (DC) affects relationship satisfaction among couples facing haematological cancer. Furthermore, we tested complex interactions between distress, disease-related and socio-demographic factors. In a multicentre study, 327 patients (haemato-oncological cancer; mean age: 57 years, 63% male) and their partners responded to surveys examining their relationship satisfaction, DC and distress. The Actor-Partner-Interdependence-Model (APIM) and moderator analyses were used to assess interactions between these concepts. In the APIM, positive DC was significantly related to greater levels of relationship satisfaction, and negative DC was related to lower levels of relationship satisfaction (all p relationship satisfaction of the partners (p relationship duration had significant moderating effects on the association between DC and relationship satisfaction (p relationship. They imply that strengthening positive DC in a couple facing haematological cancer can contribute to them having a well-functioning and sustaining relationship. © 2016 John Wiley & Sons Ltd.

    Full Text Available Twenty four Anatolian Black cows with primary ketosis (PK and 10 clinically healthy cows (considered as control were used in the study. The clinical, haematological, serum biochemical and cytogenetical parameters of all the animals were measured. Primary clinical signs included diminished appetite, decreased milk production, loss of weight, firm faeces and depression. Although no significant differences were seen with regard to haematological findings between PK and the control groups, significance increases (P<0.05 in aspartate aminotransferase (AST, gamma-glutamyl transpeptidase (GGT and urea concen- trations were observed in PK group compared to the control group. Glucose concentration was significantly low and reversely correlated to ketone bodies in urine in the PK group, but it was within normal limits in the control group. GTL- banded karyotypes of the animals were obtained using the standard karyotype of Bos taurus. Chromosomal complements were 2n = 60 in Anatolian Black cattle of normal and diseased groups. In the light of these molecular cytogenetic data, it was detected that all the autosomal chromosomes were acrocentric and gonosomal chromosomes were submetacentric. The results of the study showed that no morphological differences occurred in chromosomes in cattle suffering from PK.

    Haematological and genetic observations have been made on 71 SS Eti-Turk patients and their relatives from Cukurova (southern Turkey) and of immigrant families in The Netherlands. Similar data were collected for 25 Black patients and their relatives from Surinam, Netherlands Antilles, and Kenya. Haematological and clinical results were the same for both groups; the haemolytic anaemia in the Turkish patients was as severe as in the others. Haplotyping, involving nine restriction sites, identified haplotype 19 (Antonarakis et al, 1984) as the major type among the Eti-Turks; this chromosome has previously primarily been observed among SS patients from West Africa. The suggestion that the beta S-chromosome among Eti-Turks originates from that area is supported by a relatively high incidence of alpha-thalassaemia-2 (the 3.7 kb deletion), also frequently present in the Black population of West Africa, and by the absence of other major haplotypes, such as types 20 and 3, characteristic for the beta S-chromosome in the population of Central Africa and Kenya, and in Senegal, respectively. The Saudi Arabian type of beta S chromosome in association with the haplotype 19 beta S chromosome was present in only one Eti-Turk patient; this 30-year-old female was mildly affected and exhibited a high level of fetal haemoglobin.

    The aim of this retrospective study was to assess prevalence, risk factors, clinical presentation and outcome of phenobarbitone induced haematological abnormalities (PBIHA) in dogs. The medical records of two veterinary referral institutions were searched for dogs diagnosed with idiopathic epilepsy and treated with PB as monotherapy or polytherapy between March 2003 and September 2010. Sixteen dogs had PBIHA; the median age at diagnosis was 69.5 months. Phenobarbitone was administered at a median dose of 3 mg/kg twice a day for a median period of 100.5 days and the median serum phenobarbitone level was 19 μg/ml. Two dogs had neutropenia, three had anaemia and thrombocytopenia, two had anaemia and neutropenia; the remaining nine had pancytopenia. All dogs were referred for non-specific clinical signs. Phenobarbitone was discontinued after diagnosis, and the median time to resolution of PBIHA was 17 days. The prevalence and risk factors for PBIHA were evaluated from a questionnaire survey of referring practices to obtain more detailed follow-up on cases diagnosed with idiopathic epilepsy. The prevalence rate of PBIHA was 4.2%, and the condition occurred in dogs treated with standard therapeutic doses often within the first three months after starting treatment. Serial haematological evaluations should be therefore considered from the beginning of phenobarbitone therapy to allow early diagnosis and treatment of PBIHA.

    In this study we aimed to compare the reporting unit size used by Australian laboratories for routine chemistry and haematology tests to the unit size used by learned authorities and in standard laboratory textbooks and to the justified unit size based on measurement uncertainty (MU) estimates from quality assurance program data. MU was determined from Royal College of Pathologists of Australasia (RCPA) - Australasian Association of Clinical Biochemists (AACB) and RCPA Haematology Quality Assurance Program survey reports. The reporting unit size implicitly suggested in authoritative textbooks, the RCPA Manual, and the General Serum Chemistry program itself was noted. We also used published data on Australian laboratory practices.The best performing laboratories could justify their chemistry unit size for 55% of analytes while comparable figures for the 50% and 90% laboratories were 14% and 8%, respectively. Reporting unit size was justifiable for all laboratories for red cell count, >50% for haemoglobin but only the top 10% for haematocrit. Few, if any, could justify their mean cell volume (MCV) and mean cell haemoglobin concentration (MCHC) reporting unit sizes.The reporting unit size used by many laboratories is not justified by present analytical performance. Using MU estimates to determine the reporting interval for quantitative laboratory results ensures reporting practices match local analytical performance and recognises the inherent error of the measurement process.

    Full Text Available These studies were conducted to determine the effects of two varieties of sorghum, Samsorg 17 and ICSV 400 on the haematological and serum biochemical parameters of local turkey breeds, reared in Nigeria. Two hundred and sixteen poults were divided into 9 treatment groups of 24 each, which were further replicated thrice and fed starter diets containing Samsorg 17 and ICSV 400. Similar (P > 0.05 RBC and PCV values were obtained with the two diets. Samsorg 17 fed poults produced lower, though not significantly (P > 0.05 serum albumin, glucose, urea, creatinine, sodium, chloride, ALP, SGPT and SGOT values than those on ICSV 400 diet. Higher RBC, MCHC, MCH, MCV and PCV values were observed with Samsorg 17 fed turkeys than those on ICSV 400 diets. Serum glucose and creatinine decreased and SGOT increased with dietary sorghum. Similar (p > 0.05 Hb, WBC, MCHC, MCV and PCV values were obtained in all groups. Values of serum biochemical indices assayed except urea, calcium, potassium and chloride showed no significant (p > 0.05 differences among the treatment groups. It was therefore concluded that Samsorg 17 and ICSV 400 sorghum varieties could sustain local turkey production without any on toward effects on their haematological and serum biochemical indices.

    The Sysmex XS-1000i is a compact new, fully automated haematology analyser, designed to generate complete blood counts with five-part leucocyte differential. In our study, a Sysmex XS-1000i instrument was evaluated according to Clinical Laboratory Standards Institute (CLSI) and International Council for Standardization in Haematology (ICSH) guidelines. Precision, carry-over and linearity were determined. Using a total of 700 patient samples, results from the Sysmex XS-1000i were compared with those from a Sysmex XE-2100, an Abbott Cell Dyn 4000 and the manual reference leucocyte differential. Using quality control material, total and within-run imprecision was less than 3% except for platelets. The system demonstrated good linearity over the entire reporting range and no carry-over (XS-1000i showed good correlation with XE-2100, CD-4000 and the manual reference leucocyte differential. Overall flagging sensitivity and specificity were 91% and 48%, respectively. In conclusion, the Sysmex XS-1000i demonstrated good analytical performance, is able to generate a complete blood count with five-part differential on low blood volumes and has considerable back-up capacity.

    Full Text Available 10 hybrid ISA Brown hens, 50 weeks old, hold single in cages and fed with combined granulated forage, were monitored for a period of 3 weeks. They were divided into 4 groups depending on the stages of the egg formation. When 53 weeks old, the the blood samples were prevailed and thereafter prepared to determine the haematological parameters and the calcemia and phosphoremia.. The values of haematological parameters (the eritrocytes sedimentation rate, the haemoglobine content, the haematocrit and the leukocitar formula are within the normal limits and that no variations appear depending on the egg position in the oviduct. The calcemia values are within the normal limits (20-35 mg% for hens during their laying period, The mean value is 34.19±0.96 mg %. The statistical processing of the data does not reveal significant differences (p>0.05 among the calcemia values, irrespective of the egg formation stage. The phosphoremia values show significant modifications during the 24-25 hours necessary for the egg formation: at 30 minutes postoviposition the mean value of the phosphoremia represented 4.86±0.14 mg%, and at 22-23 hours postoviposition the level of the blood phosphorous represented 4.64±0.10 mg%, while at 10-12 hours postoviposition the registered mean value was 6.79±0.07 mg% phosphrous.

    Full Text Available The study was conducted to determine and compare the resting values of haematological and biochemical blood indices in clinically healthy horses competing in show jumping and used for leisure activities. The experiment included twenty adult horses of Polish half-bred andWielkopolska breed which were subjected to a daily training programme typical of their type of use. Blood samples were collected at rest before feeding from the jugular external vein. Show jumpers had higher (P<0.05 red blood cell count, haematocrit value and haemoglobin concentration as well as the serum level of total protein, albumin, α2- and γ-globulin, HDL and iron. The level of β- globulin, magnesium and activity of creatine kinase were significantly higher in recreationally used horses. There were no differences in the values of red blood cell parameters (MCV, MCH, MCHC, number of leucocytes and the percentage of their respective kinds, platelets, concentration of urea, creatinine, glucose, triglycerides, total cholesterol, LDL, activity of AST, ALT, LDH and in the content of Na, K, Cl, P, Ca between the tested groups. The results of the present study indicate that the type of training influences some of the resting haematological and biochemical indices in adult horses. Horses used for show jumping have higher aerobic capacity and show a more beneficial lipid profile compared to horses used for recreation.

    The objective of this observational study is to describe clinical, haematological and serum biochemical findings of horses affected with alfalfa dodder (Cuscuta campestris) toxicity. Twenty horses naturally exposed to alfalfa dodder toxicity were examined and information was collected on history and clinical signs. Physical examination was done on horses in the premises (n=20), and venous blood samples of 12 horses were submitted for haematology and serum biochemical examination for each horse. Abnormal clinical signs started around 36 hours after horses were fed the contaminated alfalfa. Abnormal signs were seen in 11 horses and those included diarrhoea (n=8), decreased appetite (n=7), neurological signs (n=4) and abdominal pain (n=1). Some horses had multiple clinical signs of the above. The results of complete blood cell count revealed leukocytopenia, neutropenia and thrombocytopenia. Serum biochemical analysis revealed decreased ALP, AST and CPK levels and increased direct bilirubin level. The used alfalfa was stopped immediately and a different alfalfa from a new container that did not contain any weeds was fed. Horses on the premises were observed closely, and the abnormal clinical signs resolved within three days. No treatment was implemented. Knowledge about toxicity of horses by Cuscuta species is scarce in the English veterinary literature and very limited.

    Full Text Available Munchausen syndrome by Proxy is a severe form of child abuse. Disease symptoms and signs are fabricated or imitated by parents or caregivers The child is usually presented to doctors, persistently. A delay in diagnosis may cause severe negative impact on spiritual, physical, mental and social development of the cases and even death. Symptoms usually disappear in the absence of the perpetrators. The diagnosis is extremely difficult. A 21-month-old boy who had applied to many centers due to bleeding from various parts of the body for last six months, and whose symptoms could not be explained with any physical reason after tests were conducted. Finally he was admitted to our center with bloody urine and stools, and diagnosed Munchausen syndrome by proxy. In cases with recurrent hospital admission in whom no apparent disease is diagnosed, Munchausen syndrome by Proxy should be among the differential diagnosis.

    It has been argued that wormholes are as good a prediction of Einstein's theory as black holes but the theoretical construction requires a reverse strategy, specifying the desired geometric properties of the wormhole and leaving open the determination of the stress-energy tensor. We begin by confirming an earlier result by the author showing that a complete wormhole solution can be obtained by adopting the equation of state $p=\\omega\\rho$ and assuming that the wormhole admits a one-parameter group of conformal motions. The main purpose of this paper is to use the assumption of conformal symmetry to show that the wormhole is stable to linearized radial perturbations whenever $-1.5<\\omega <-1$.

We begin by confirming an earlier result by the author showing that a complete wormhole solution can be obtained by adopting the equation of state p = ωρ and assuming that the wormhole admits a one-parameter group of conformal motions. The main purpose of this paper is to use the assumption of conformal symmetry to show that the wormhole is stable to linearized radial perturbations whenever ‑ 1.5 < ω < ‑1.

    Full Text Available Introduction Suicide is considered as a public health problem. Approximately 0.9% of all deaths worldwide are due to suicide. This study was performed to identify risk factors of suicide attempts among patients who admitted in a medical toxicology centre during three months. Materials and Methods: A cross sectional study was carried out; all admitted patients in our medical toxicology centre due to suicidal attempt who completed consent form were included from December to March 2013. A researcher designed questionnaire was prepared and its validity and reliability was confirmed; it was fulfilled by a psychologist via clinical interview. Data were analyzed by SPSS software 11.5 and results were discussed. Results:198 participants included; of whom 67.2% were female and 94.9% were less than 45 year old. Among the patients, approximately 48% of the patients were married; 27.77% were employed. More than 96% suffered from severe depression, 3.53% of the patients had psychotic symptoms. Personality disorders, previous suicidal attempt, unemployment, full stressed family, family history of suicidal attempt, moderate to severe depression and a history of dependence on antipsychotic drugs and lack of family support were identified as risk factors for suicide. Conclusion: Attention to personality trait  and family environment can be mainly effective in long-term prevention of suicide, treatment of physical illness in patients with chronic health conditions, evaluation and treatment of psychiatric issues in addition to family and social problems, and organizing educational courses  to families with suicide history can be helpful.

  20. Hotel NHS and the acute abdomen - admit first, investigate later.

    To determine the financial consequences of a policy of admission first, followed by definitive investigation for patients with an admission diagnosis of suspected acute abdomen. Over a 1-month period, 122 patients were admitted with a suspected surgical diagnosis of acute abdomen (55 men, 67 women); age range 16-95 years (median: 56.5). Based on surgical operation required (n = 36), death after admission (n = 6, three postoperative deaths) and/or severe surgical illness (n = 17), 56 required surgical inpatient admission, while 66 did not. The patients who did not require admission spent significantly shorter time in hospital than those who required admission (median: 5 days vs. 8.5 days; p = 0.0000). Total hospital hotel and investigation cost (not including ITU or theatre costs) for all 122 patients was 330,468 pounds. Overall, 205,468 pounds was consumed by these 56 patients who required admission, while 125,000 pounds was spent on 66 patients whose clinical course did not justify admission; 92% of which was spent on hospital hotel costs and 8% on the cost of imaging and/or endoscopy. On a national basis, emergency General Surgery admissions account for 1000 Finished Consultant Episodes per 100,000 population. The findings of this study suggest that this equates to a national NHS spend of 650 million pounds each year, for the hotel costs of patients that could arguably avoid surgical admission altogether. Continuing to admit patients with a suspected acute abdomen first and then requesting definitive investigation makes neither clinical nor economic sense.

  1. Children’s motives for admitting to prosocial behavior

    Full Text Available There has been extensive research on children’s moral evaluation of lying in prosocial situations. Current knowledge regarding the concept of lying has been derived from studies showing that cultural differences exist, whereby non-Western children tend to rate lie-telling more positively than Western children do. These findings suggest that there are different views about whether children should publicize their prosocial behaviors and that children have universal motivations when they admit to engaging in prosocial behavior. A gender difference has also been found in relation to prosocial behavior. However, previous studies did not investigate in detail children’s motivation for admission or non-admission to prosocial behavior, and if there is a gender difference. Therefore, this study examined the diversity in and development of motivations for admitting to engaging in prosocial behavior, with the aim of clarifying whether disclosing good deeds to teachers varies as function of children’s grade level in school, and how such motivations differ with age and gender. Questionnaires from 1,345 elementary and junior high school students in Japan were analyzed. Results showed that children’s communication tendency with regard to prosocial behavior reports peaked in the fourth grade of elementary school and gradually decreased thereafter. From the third grade of elementary school onwards, children reported that they refrained from this type of communication because they feared others’ negative evaluation and wanted to comply with modesty norms. Girls were more likely than boys were to believe that it is better to tell the truth about engaging in prosocial behavior, but boys and girls had largely the same motives for not owning up to performing a desirable deed.

Minimum community based-incidence rates (MCBIRs complement hospital data, describing the malaria burden in the community. Methods A retrospective analysis of all admitted malaria cases to a Mozambican rural hospital between June 2003 and May 2005 was conducted. Prevalence and case fatality rates (CFR for each sign and symptom were calculated. Logistic regression was used to identify variables which were independent risk factors for death. MCBIRs for malaria and severe malaria were calculated using data from the Demographic Surveillance System. Results Almost half of the 8,311 patients admitted during the study period had malaria and 13,2% had severe malaria. Children under two years accounted for almost 60% of all malaria cases. CFR for malaria was 1.6% and for severe malaria 4.4%. Almost 19% of all paediatric hospital deaths were due to malaria. Prostration (55.0%, respiratory distress (41.1% and severe anaemia (17.3% were the most prevalent signs among severe malaria cases. Severe anaemia and inability to look for mother's breast were independent risk factors for death in infants younger than eight months.

    Full Text Available Background and Design: The purpose of this study was to evaluate the drug reactions observed in patients who applied to Dermatology Department and to determine which drugs caused these reactions, the type of the reactions and their frequency.Materials and Methods: A total of 193 patients admitted to the Dermatology Department with the diagnosis of drug reaction between January 2008 and December 2009 were retrospectively evaluated. Age, sex, symptoms, laboratory tests, diagnosis and treatment information were obtained by examining the patient record forms. Results: During the period of twenty-four months, 193 patients were admitted to the Dermatology Department. 107 (55.4% of them were female and 86 (44.6% were male. The patients were aged between 8 month and 80 years with a mean age of 37.00±2.5 years. The duration from drug intake to the development of lesions ranged from 15 minutes to 1 year. The most common drug reaction was urticaria (72 patients and the other reactions were maculopapular drug eruptions (31 patients, fixed drug eruption (24 patients, and pruritus (14 patients. The most common drugs held responsible were antibiotics (63 patients, 32.6% followed by analgesics (37 patients, 19.2 %, and antihypertensive drugs (19 patients, 9.8%. Twenty-nine patients (15.0% were diagnosed histopathologically. Nineteen patients had mild transaminase elevation, while no complications were detected in the other systems. The drug reactions were accompanied by atopy in 26 patients. Conclusion: Based on the results of the present study, the most common drug reactions are urticaria-angioedema, maculopapular eruption, and fixed drug eruption and the most frequent causative agents are antibiotics, analgesics, and anti-hypertensive drugs.

    Full Text Available Neuroleptic malignant syndrome (NMS is a potentially fatal adverse event associated with the use of antipsychotics (AP. The objective of this study was to investigate the profile of cases of NMS and to compare our findings with those published in similar settings. A series of 18 consecutive patients with an established diagnosis of NMS was analyzed, gathering data on demography, symptoms and signs. Two thirds of all cases involved woman with a past medical history of psychiatric disorder receiving relatively high doses of AP. The signs and symptoms of NMS episodes were similar to those reported in other series and only one case had a fatal outcome, the remaining presenting complete recovery. As expected, more than two thirds of our cases were using classic AP (68%, however the clinical profile of these in comparison with those taking newer agent was similar. Newer AP also carry the potential for NMS.

    Full Text Available Malignant peritoneal mesothelioma (MPM is rare. It is difficult to diagnose early and responds poorly to treatment. There is no optimal and effective treating consensus so far. We report three patients of MPM treated at Mackay Memorial Hospital in recent 3 years. They were two men and one woman without asbestos exposure related to their occupations. Due to failure in early diagnosis of MPM, none of them survived for more than 5 months. We make a brief review from the previous literature. These three cases were compared with the reviewing data in many aspects including the risk factor, clinical presentation, diagnostic options, and management. Besides, some latest clinical trials are introduced in this report.

    Full Text Available A 50-year-old lady presented with complaints of chest pain and cough for the past one month. Right supraclavicular lymphadenopathy, bilateral pleural effusion were present. Fine needle aspiration cytology (FNAC from the lymph node showed brownish-black pigment laden tumour cells. Review of history subsequently revealed that she had undergone a surgical procedure over the sole of her left foot three years ago of which no records were available. Reexamination of sole of left foot showed a pigmented infiltraling lesion. Pleural biopsy revealed pigmented tumour deposits. The patient was diagnosed to have fulminant metastatic malignant melanoma of left foot with metastasis to cervical lymph nodes and pleura. This case report re-emphasizes the importance of combined approach to ascertain diagnosis early.

    Peritoneal mesotheliomas are unusual entities with diverse origins and outcomes. Both benign and malignant variants exist. Benign multicystic peritoneal mesotheliomas (BMPMs), also known as multiple or multilocular peritoneal inclusion cysts, are extremely rare tumours arising from the peritoneal mesothelium covering the abdominal serous cavity. Even though these entities are considered benign tumours, BMPMs tend to recur after surgical resection, and in two cases have been reported to undergo malignant transformation. In contrast, diffuse malignant peritoneal mesotheliomas, while also quite rare, are the second most common form of malignant mesothelioma after the pleural variety with extremely high mortality and poor response to many treatments to date. We present a rare case of diffuse malignant peritoneal mesothelioma within a large component of a BMPM in a young man admitted to our service.

    Full Text Available Haematological and cytokine alterations in malaria are a broad and controversial subject in the literature. However, few studies have simultaneously evaluated various cytokines in a single patient group during the acute and convalescent phases of infection. The aim of this study was to sequentially characterise alterations in haematological patters and circulating plasma cytokine and chemokine levels in patients infected with Plasmodium vivax or Plasmodium falciparum from a Brazilian endemic area during the acute and convalescent phases of infection. During the acute phase, thrombocytopaenia, eosinopaenia, lymphopaenia and an increased number of band cells were observed in the majority of the patients. During the convalescent phase, the haematologic parameters returned to normal. During the acute phase, P. vivax and P. falciparum patients had significantly higher interleukin (IL-6, IL-8, IL-17, interferon-γ, tumour necrosis factor (TNF-α, macrophage inflammatory protein-1β and granulocyte-colony stimulating factor levels than controls and maintained high levels during the convalescent phase. IL-10 was detected at high concentrations during the acute phase, but returned to normal levels during the convalescent phase. Plasma IL-10 concentration was positively correlated with parasitaemia in P. vivax and P. falciparum-infected patients. The same was true for the TNF-α concentration in P. falciparum-infected patients. Finally, the haematological and cytokine profiles were similar between uncomplicated P. falciparum and P. vivax infections.

    Retrospective studies have documented a significant association between linezolid (LNZ) plasma concentrations and drug-related haematological toxicity. However, the safe upper threshold level for LNZ plasma trough concentrations (Cmin values) has not been defined with certainty. A prospective observational study was performed aimed at comparing LNZ Cmin values in patients developing drug-related side effects with those measured in patients not experiencing LNZ toxicity. LNZ Cmin values were measured from the first week after starting therapy and were repeated periodically up to the end of treatment. Fifty patients, for a total of 210 LNZ Cmin evaluations, were considered. All patients (n=9) who developed drug-related haematological toxicity also had significantly higher plasma LNZ Cmin values during the first week of therapy (9.0±6.4 mg/L vs. 4.9±3.7 mg/L; P<0.01) and thereafter (9.3±5.4 mg/L vs. 4.4±3.4 mg/L; P<0.01). The significant association between LNZ plasma concentrations and haematological toxicity was also confirmed by multivariate logistic regression analysis including age, serum creatinine and concomitant medications as independent variables. A causal relationship between LNZ concentrations and the risk of developing drug-related haematological toxicity was observed. Accordingly, application of therapeutic drug monitoring may improve the safety outcome of patients receiving LNZ therapy.

    Following the accompanying ADMIT (the ALMA Data Mining Toolkit) paper by Teuben et al. (2013), we explore the power of the ADMIT schema. ADMIT could be used to data mine across multiple ALMA datasets, projects, or sources, adding value to the ALMA archive. ADMIT will be capable of defining a set of sources in a local virtual project. This project could have the ADMIT analyses recomputed in a common fashion, or to a common level, and add new data products. The sources in the virtual project could also be grouped based on similarities, either by the user or due to decisions made by ADMIT, and have their data abstracted for further analysis and visualization inside or outside of ADMIT in a native Python environment. In this paper we describe the design and techniques of this capability.

    From October 1986 to June 1989, 79 patients with malignant tumors were treated by radiation therapy combined with hyperthermia at National Medical Center Hospital. Seventy two patients (male: 48, female: 23) were evaluable. Average age was 62.4 years old (ranged 20-81 years old). Irradiation was delivered twice to fifth weekly in tumor doses of 50 to 60 Gy (TDF 82-122). We used 3 types of hyperthermic equipment, Thermotron RF8, BSD 1000 System and Endoradiotherm 100A. Hyperthermia was initiated within 30 minutes following irradiation, most of the patients being treated with adequate equipment, 41-44degC, for 60-70 minutes every 72 hours. Fifteen of 71 patients (20.8%) showed a complete response and 36 patients (50%) showed a partial response, so effective rate was 70.8% of all. In superficial tumors, 4 of 21 patients (21.5%) showed a complete response and 8 of 21 patients showed a partial response, effective rate was 63.2% of all. In deep seated tumor, 10 of 46 patients (21.7%) showed a complete response and 25 of all patients showed a partial response, so effective rate was 76.1% of all. Five patients were heated following only intra-tumor injection of OK-432 and its effective rate was 75%. We think that this modality of therapy will be effective in cases which heating area had been irradiated over tolerable doses. CR rate of superficial tumors according to intra-tumor center temperature tends to higher in the cases of higher tumor temperature. In deep seated tumor, 11 patients (23.9%) had reached over 43degC, 29 patients (63.0%) heated 41-43degC, 6 patients (13.0%) heated under 41degC and CR rate of each group were 36.4%, 17.2%, 16.7%, respectively. We think that thermotherapy with irradiation is an effective therapy in the treatment of malignancies but the improvement of heating equipment will be expected. (author).

    Neuroleptic Malignant Syndrome (NMS) is an idiosyncratic and potentially life-threatening reaction to neuroleptic drugs. Lithium is a first-line mood stabilizer used in the treatment and prophylaxis of bipolar disorder. There are several case reports of lithium-associated NMS, but only when it was given in combination with antipsychotics. Therefore, the possibility of NMS being secondary to the antipsychotics could not be ruled out in those cases. Here we present a case of lithium-induced NMS in a patient who was not being treated concomitantly with any other agent known to cause NMS. The patient, a 74-year-old female with a 30-year history of bipolar affective disorder, was admitted to the emergency room of the All India Institute of Medical Sciences, New Delhi, with history of high fever and generalized weakness for 10 days before the admission. NMS was established based the presence of three cardinal symptoms. She was started on intravenous fluids to correct her sodium levels slowly and requested to follow-up at the psychiatry clinic.

The limit dose test of Up and Down procedure as revised by Dixon was employed to determine the acute oral toxicity of the plant.  The result revealed that the Median lethal dose of the plant is greater than 3000mg/kg body weight. The repeated administration of graded doses of  the extract showed a  significant (P<0.05 dose dependent increase in the packed cell volume (PCV and red blood cells count on 21st and 28th day post extract treatment. However, there were no significant (P>0.05 difference in the total white blood cells and differential leukocyte count in all the treated groups of rats compared to there respective day zero and control group. These results show that the aqueous stem extract of Anisopus mannii is relatively safe following oral administration and have possible stimulatory effect on red blood cell production.   Industrial relevance: Blood is a good indicator to determine the physiological and pathological status of man and animal. The parameters measured include packed cell volume, haemoglobin, white blood cell count and platelets count. The normal ranges of these parameters can be altered by the ingestion of some toxic plants. The plant Anisopus mannii (Family Asclepiadaceae, is known as ‘Sakayau’ or ‘Kashe zaki’( meaning sweet killer among the Hausas of the northern Nigeria, where a cold decoction of the stem is traditionally used as remedy for hyperglycaemia. Despite the widespread use of this plant in this environment, there is little literature on the scientific evaluation of its haematological effect thus screening of plants for toxicity aiming at ascertaining their safety seems to be promising, as toxicity following overdose or the active principles present in the plant could pose as limitation to their potential usefulness and may even lead to death.

    Increased incidence of cancer at various sites is observed in patients with end-stage renal disease (ESRD). Certain malignant diseases, such as lymphomas and carcinomas of the kidney, prostate, liver and uterus, show an enhanced prevalence compared with the general population. In particular, renal cell carcinoma (RCC) shows an excess incidence in ESRD patients. A multitude of factors, directly or indirectly associated with the renal disease and the treatment regimens, may contribute to the increased tumor formation in these patients. Patients undergoing renal replacement therapy (RRT) are prone to develop acquired cystic kidney disease (ACKD), which may subsequently lead to the development of RCC. In pre-dialysis patients with coexistent renal disease, as in dialysis and transplant patients, the presence of ACKD may predispose to RCC. Previous use of cytotoxic drugs (eg, cyclophosphamide) or a history of analgesic abuse, are additional risk factors for malignancy. Malignancy following renal transplantation is an important medical problem during the follow-up. The most common malignancies are lymphoproliferative disorders (early after transplantation) and skin carcinomas (late after transplantation). Another important confounder for risk of malignancy after renal transplantation is the type of immunosuppression. The type of malignancy is different in various countries and dependent on genetic and environmental factors. Finally, previous cancer treatment in a uremic patient on the transplant waiting list is of great importance in relation to waiting time and post-malignancy screening.

    Full Text Available BACKGROUND: Internal malignancies are accompanied by various skin changes which may be specific infiltrates or non-specific changes. This study is aimed at determining the frequency of such changes in malignant disease treatment center attendees in India. METHODS: A study of 300 confirmed cases of internal malignancy at a malignant disease treatment center was undertaken to evaluate these skin changes. Specific infiltrates were confirmed by histopathology. Statistical methods were employed to calculate significance in non-specific lesions by comparing with 300 controls not suffering from internal malignancy. RESULTS: Skin changes were present in 82 (27.3%. Cutaneous metastases were found in 19 (6.3%; non-contiguous in 5 (1.6%; contiguous in 14 (4.3%. Non-specific skin lesions numbered 74 (11.6% in 52 patients. Statistically significant non-specific skin changes were acquired ichthyosis, herpes zoster and generalized pruritus. CONCLUSION: Metastases usually occurred late in internal malignancy (17, 5.6% except in a case each of histiocytic lymphoma and non-Hodgkin′s lymphoma (2, 0.7% where the lesions preceded malignancy by 3 months and 1 month respectively. Contiguous nodules were a marker of relapse after surgery in 3 (1%.

  10. Refining a relativistic, hydrodynamic solver: Admitting ultra-relativistic flows

    Bernstein, J. P.; Hughes, P. A.

    2009-09-01

    We have undertaken the simulation of hydrodynamic flows with bulk Lorentz factors in the range 102-106. We discuss the application of an existing relativistic, hydrodynamic primitive variable recovery algorithm to a study of pulsar winds, and, in particular, the refinement made to admit such ultra-relativistic flows. We show that an iterative quartic root finder breaks down for Lorentz factors above 102 and employ an analytic root finder as a solution. We find that the former, which is known to be robust for Lorentz factors up to at least 50, offers a 24% speed advantage. We demonstrate the existence of a simple diagnostic allowing for a hybrid primitives recovery algorithm that includes an automatic, real-time toggle between the iterative and analytical methods. We further determine the accuracy of the iterative and hybrid algorithms for a comprehensive selection of input parameters and demonstrate the latter’s capability to elucidate the internal structure of ultra-relativistic plasmas. In particular, we discuss simulations showing that the interaction of a light, ultra-relativistic pulsar wind with a slow, dense ambient medium can give rise to asymmetry reminiscent of the Guitar nebula leading to the formation of a relativistic backflow harboring a series of internal shockwaves. The shockwaves provide thermalized energy that is available for the continued inflation of the PWN bubble. In turn, the bubble enhances the asymmetry, thereby providing positive feedback to the backflow.

    2012-10-01

    Meningitis is a common admission diagnosis. No case series or descriptive studies on meningitis have recently been published. Additionally, no recent data exist on meningitis in the U.S. Military Health System. We reviewed charts of adult patients admitted to Naval Medical Center San Diego between January 2004 and December 2008 with an admission diagnosis of meningitis. Charts were excluded if they did not meet our case definition of meningitis, if missing data, or if meningitis was nosocomial or iatrogenic. We reviewed results of cerebrospinal fluid cultures during this period. We compared rates and characteristics, and outcomes of bacterial and aseptic meningitis. Two hundred twenty-one cases met our criteria. Of these, 208 were aseptic. Cerebrospinal fluid polymerase chain reaction testing was positive for enteroviruses and herpes simplex viruses in 42 (20.2%) and 17 (8.2%) cases, respectively. Of culture/polymerase chain reaction/serologically positive cases, the pathogens were Neisseria meningitidis (3), Streptococcus pneumoniae (3), viridans streptococci (2), Cryptococcus neoformans (2), Coccidioides immitis (2), and Mycobacterium tuberculosis (1). Three patients had poor outcomes: one died from S. pneumoniae and two had long-term neurologic deficits. Meningitis is a common admission diagnosis, but serious virulent pathogens are uncommon and adverse outcomes are rare.

    AIM To determine the true prevalence of thrombocytosis in children less than 2 years of age with bronchiolitis, its association with risk factors, disease severity and thromboembolic complications. METHODS A retrospective observational medical chart review of 305 infants aged two years or less hospitalized for bronchiolitis. Clinical outcomes included disease severity, duration of hospital stay, admission to pediatric intensive care unit, or death. They also included complications of thrombocytosis, including thromboembolic complications such as cerebrovascular accident, acute coronary syndrome, deep venous thrombosis, pulmonary embolus, mesenteric thrombosis and arterial thrombosis and also hemorrhagic complications such as bleeding (spontaneous hemorrhage in the skin, mucous membranes, gastrointestinal, respiratory, or genitourinary tracts). RESULTS The median age was 4.7 mo and 179 were males (59%). Respiratory syncytial virus was isolated in 268 (84%), adenovirus in 23 (7%) and influenza virus A or B in 13 (4%). Thrombocytosis (platelet count > 500 × 109/L) occurred in 88 (29%; 95%CI: 24%-34%), more commonly in younger infants with the platelet count declining with age. There was no significant association with the duration of illness, temperature on admission, white blood cell count, serum C-reactive protein concentration, length of hospital stay or admission to the intensive care unit. No death, thrombotic or hemorrhagic events occurred. CONCLUSION Thrombocytosis is common in children under two years of age admitted with bronchiolitis. It is not associated with disease severity or thromboembolic complications. PMID:28540196

    Full Text Available Renal malignancies are common in children. While the majority of malignant renal masses are secondary to Wilms tumor, it can be challenging to distinguish from more aggressive renal masses. For suspicious renal lesions, it is crucial to ensure prompt diagnosis in order to select the appropriate surgical procedure and treatment. This review article will discuss the common differential diagnosis that can be encountered when evaluating a suspicious renal mass in the pediatric population. This includes clear cell sarcoma of the kidney, malignant rhabdoid tumor, renal medullary carcinoma and lymphoma.

    Full Text Available Ewing's sarcoma (ES is a rare tumor that is most common in children and young adults. Late effects of ES therapy include second cancers, a tragic outcome for survivors of such a young age. This paper will explore the frequencies and types of malignancies that occur after ES. Additionally, it will review how second malignancies have changed with the shift in treatment from high-dose radiation to chemotherapy regimens including alkylators and epipodophyllotoxins. The risk of additional cancers in ES survivors will also be compared to survivors of other childhood cancers. Finally, the possible genetic contribution to ES and second malignancies will be discussed.

    Some biochemical and haematological variables were measured in piglets during the first 48 hours after birth. The piglets were reared either by the sow, or bottle-fed with colostrum (either natural or sterilised by irradiation), or a commercial milk replacer. Mean haemoglobin concentrations, packed cell volumes and erythrocyte counts decreased by approximately 45 per cent in all the groups between birth and 48 hours, but leucocyte counts increased more markedly in the colostrum-fed groups. All the colostrum-fed groups showed rapid increases in serum total protein concentrations which were almost entirely due to increases in gamma globulin concentrations. There was no difference in this respect between natural colostrum and colostrum sterilised by irradiation with 500 Krad of gamma rays. Colostrum sterilised by irradiation can protect piglets against infectious agents and simplify the rearing of piglets under specific pathogen free conditions.

    Prenatal Ultrasound (US) is commonly used as a routine procedure on pregnant women. It is generally perceived as a safe procedure due to the use of non-ionizing radiation. However, the neurotoxicity of diagnostic prenatal US was detected to have a correlation with high susceptibility to early developing fetus. This research involved in vivo experimental model by using 3(rd) trimester pregnant Oryctolagus cuniculus and exposing them to US exposures for 30, 60, and 90 minutes at their gestational day (GD) 28-29. The output power and intensities, spatial peak temporal average intensity (ISPTA) of US were varied from 0.4 to 0.7 W and 0.13 to 0.19 W/cm(2) respectively were tested initially in free-field, water. Haematological analysis was carried out to detect any changes in blood constituents. Statistically significant differences were detected in red blood cell (RBC) count (Pheating in causing defects on studied animal.

    Cyprinus carpio communis Linnaeus, Carassius carassius Linnaeus, Schizothorax curvifrons Heckel and Triplophysa marmorata species of fishes were captured from Anchar Lake and river Jhelum of Kashmir Himalaya for hematological and parasitological analysis. During the investigation haemoflagellates from the genus Babesiosoma and Trypanosoma were recorded in the blood smears. Trypanosomes were present in all the species except C. carpio, whereas Babesiosoma were only found in T. marmorata. Haematological analysis revealed a significant (p<0.01) reduction in red blood cell count in the fishes infected with Babesiosoma and Trypanosoma. A significant decrease (p<0.05) was recorded in haemoglobin value and packed cell volume in the infected fishes in comparison to the non-infected fishes. PMID:26623319

    To obtain more information on the effects of long-lasting endurance and strength training on the constituents of the blood, several haematological and iron-related parameters were measured at rest in 39 male athletes from the Polish team who participated in the Olympics in Seoul in 1988. The athletes were divided into two groups: endurance-trained subjects (group E, cyclists, canoeists and rowers; n = 22) and strength-trained subjects (group S, wrestlers and judo; n = 17). The control group was composed of untrained male subjects (n = 48). Blood samples were taken from an antecubital vein with the subject at rest for determinations of haemoglobin concentration ([Hb]), packed cell volume (PCV), erythrocyte (RBC) and reticulocyte count, plasma free haemoglobin concentration, haptoglobin concentration, serum iron, transferrin concentration and ferritin concentrations ([Ferr]); red blood cells were used for estimation of glutamato-oxalate transaminase (GOT) activity and free erythrocyte protoporphyrin concentration ([FEP]). The mean [Hb], PVC, RBC measured in the E athletes were significantly lower than in the control group but were comparable to those obtained in the S atheletes. There were no significantly differences in the haematological indices [mean corpuscular volume (MCV), mean copuscular haemoglobin and mean corpuscular haemoglobin concentration] between the groups of atheletes and the control group. A significant increase in reticulocytosis and GOT activity was observed in the endurance-trained athletes. No impairment of erythropoiesis was observed as indicated by several sensitive markers of haemoglobin formation (FEP, MCV and inspection of blood smears) in the athletes.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Haematology parameters (N = 24 and serum biochemistry parameters (N = 35 were determined for wild Eurasian beavers (Castor fiber, between 6 months - 12 years old. Of the population tested in this study, N = 18 Eurasian beavers were from Norway and N = 17 originating from Bavaria but now living extensively in a reserve in England. All blood samples were collected from beavers via the ventral tail vein. All beavers were chemically restrained using inhalant isoflurane in 100% oxygen prior to blood sampling. Results were determined for haematological and serum biochemical parameters for the species and were compared between the two different populations with differences in means estimated and significant differences being noted. Standard blood parameters for the Eurasian beaver were determined and their ranges characterised using percentiles. Whilst the majority of blood parameters between the two populations showed no significant variation, haemoglobin, packed cell volume, mean cell haemoglobin and white blood cell counts showed significantly greater values (p<0.01 in the Bavarian origin population than the Norwegian; neutrophil counts, alpha 2 globulins, cholesterol, sodium: potassium ratios and phosphorus levels showed significantly (p<0.05 greater values in Bavarian versus Norwegian; and potassium, bile acids, gamma globulins, urea, creatinine and total calcium values levels showed significantly (p<0.05 greater values in Norwegian versus Bavarian relict populations. No significant differences were noted between male and female beavers or between sexually immature (<3 years old and sexually mature (≥3 years old beavers in the animals sampled. With Eurasian beaver reintroduction encouraged by legislation throughout Europe, knowledge of baseline blood values for the species and any variations therein is essential when assessing their health and welfare and the success or failure of any reintroduction program.

    Scuba diving represents a combination of exercise and changes in environmental conditions. This study aimed to evaluate changes in haematological parameters after recreational scuba diving in order to identify clinically significant changes. The study included males, 17 recreational divers, median age (range) 41 (30-52) years. Blood samples were taken before diving, immediately after diving to 30 meters for 30 minutes, 3 hours and 6 hours after diving. Complete blood counts were analyzed on the Cell Dyn Ruby haematology analyzer. Statistical significance between successive measurements was tested using Friedman test. The difference between the two measurements was judged against desirable bias (DSB) derived from biological variation and calculated reference change values (RCV). The difference higher than RCV was considered clinically significant. A statistically significant increase and difference judging against DSB was observed: for neutrophils immediately, 3 and 6 hours after diving (18%, 34% and 36%, respectively), for white blood cells (WBCs) 3 and 6 hours after diving (20% and 25%, respectively), for lymphocytes (20%) and monocytes (23%) 6 hours after diving. A statistically significant decrease and difference judging against DSB was found: immediately after diving for monocytes (- 15%), 3 and 6 hours after diving for red blood cells (RBCs) (- 2.6% and -2.9%, respectively), haemoglobin (- 2.1% and - 2.8%, respectively) and haematocrit (- 2.4% and - 3.2%, respectively). A clinically significant change was not found for any of the test parameters when compared to RCV. Observed statistically significant changes after recreational scuba diving; WBCs, neutrophils, lymphocytes, monocytes increase and RBCs, haemoglobin, haematocrit decrease, probably will not affect clinical decision.

    Full Text Available Use of current models of Automated Haematology Analysers help in calculating the haemoglobin contents of the mature Red cells, Reticulocytes and percentages of Microcytic and hypochromic Red cells. This has helped the clinician in reaching early diagnosis and management of Different haemopoietic disorders like Iron Deficiency Anaemia, Thalassaemia and anaemia of chronic diseases. AIM This study is conducted using an Automated Haematology Analyser to evaluate anaemia using the Red Cell and Reticulocyte parameters. Three types of anaemia were evaluated; iron deficiency anaemia, anaemia of long duration and anaemia associated with chronic disease and Iron deficiency. MATERIALS AND METHODS The blood samples were collected from 287 adult patients with anaemia differentiated depending upon their iron status, haemoglobinopathies and inflammatory activity. Iron deficiency anaemia (n=132, anaemia of long duration (ACD, (n=97 and anaemia associated with chronic disease with iron deficiency (ACD Combi, (n=58. Microcytic Red cells, hypochromic red cells percentage and levels of haemoglobin in reticulocytes and matured RBCs were calculated. The accuracy of the parameters was analysed using receiver operating characteristic analyser to differentiate between the types of anaemia. OBSERVATIONS AND RESULTS There was no difference in parameters between the iron deficiency group or anaemia associated with chronic disease and iron deficiency. The hypochromic red cells percentage was the best parameter in differentiating anaemia of chronic disease with or without absolute iron deficiency with a sensitivity of 72.7% and a specificity of 70.4%. CONCLUSIONS The parameters of red cells and reticulocytes were of reasonably good indicators in differentiating the absolute iron deficiency anaemia with chronic disease.

    β-Thalassaemia is widely found in Southwestern China. Characterisation of β-thalassaemia can improve screening and prenatal diagnosis for at-risk populations. A retrospective study. In this study, the levels of haemoglobin alpha 2 (HbA2) and haemoglobin alpha (HbA) were analysed by gender for a total of 15 067 subjects screened by capillary electrophoresis. The cut-off value with the highest accuracy was established to identify β-thalassaemia in 723 patients suspected to have this disease. Haematological and electrophoretic characterisation of eight common types of β-thalassaemia were analysed in 486 β-thalassaemia subjects. HbA levels were significantly higher in men than in women, but there was no significant difference on HbA2 levels. A new cut-off value for the diagnosis of β-thalassaemia (HbA2≥4.0%) with the highest accuracy was proposed for the studied populations. Haemoglobin (Hb) was significantly higher in men compared with women (pG) (HBB (β-globin):c.-78A>C) had significantly higher HbA2 values compared with other β-thalassaemia. Ethnic groups have diversified β-globin gene mutations and considerable haematological variations. Our study will lay the foundation for screening programmes and clinical management of thalassaemia in Southwestern China. Published by the BMJ Publishing Group Limited.

    Full Text Available Outbreak of disease is an important limiting factor in aquaculture. Incorporation of herbal immunostimulants in diet is one of the widely followed methods to improve the general resistance in fish. The present experiment was carried out to evaluate the Immunostimulatory potential of the medicinal herb Phyllanthus amarus in fish. The experiment was carried out in two sets. In experiment-I, one group of Labeo rohita was fed with control diet (‘C’ diet and the other group was fed with Phyllanthus amarus incorporated diet (‘P’ diet for 14 days and the haematological parameters were analysed on 1st, 3rd, 7th and 14th day of the experiment. Significant increase in Total Erythrocyte Count (TEC, Haemoglobin (Hb g%, Total Leucocyte Count (TLC, lymphocytes, monocytes and neutrophils were observed in ‘P’ diet fed fishes with increase in the duration of the experiment. As there is positive response in the first experiment hence experiment-II was carried out. In experiment-II, One group of Labeo rohita were fed with ‘C’ diet and other group received ‘P’ diet for 14 days, post-infected with Aeromonas hydrophila and haematological parameters were analyzed on 1st, 3rd, 7th & 14th days after infection. Significant increase in TEC, Hb, TLC, lymphocytes and a steady population of monocytes and neutrophils were observed in ‘P’ diet fed fishes. On the other hand basophils and eosinophil count exhibited a fluctuating trend. Thus dietary incorporation of Phyllanthus amarus helps to improve the general health and resistance of the fish.

    Full Text Available Background: Referral of samples for the work-up of haematological disorders from remote laboratories can result in a delay in analysis.Objective: The stability of the full blood count (FBC, differential count (DIFF, reticulocyte and peripheral blood smear (PBS morphology during extended storage was evaluated.Methods: Forty blood samples stored in ethylenediaminetetraacetic acid (EDTA were analysed on an ADVIA® 120 haematology analyser. The samples (25% abnormal; 75% normal were stored at room temperature (RT and at 4 °C – 8 °C. Analysis of samples stored at RT was performed every 12 hours for two days. Analysis of samples stored at 4 °C – 8 °C was performed at 12 hours and subsequently every 24 hours for seven days.Results: FBC parameters (red cell count, haemoglobin and DIFF parameters (percentages of basophils, lymphocytes and monocytes were stable for at least 48 hours when stored at RT. Platelets were only stable for 12 hours and the white cell count was stable for 36 hours when stored at RT. Storing samples at 4 °C – 8 °C significantly increased the stability of most parameters, in particular, mean cell volume and percentage of reticulocytes. However, DIFF parameters were associated with lower stability at 4 °C – 8 °C. PBS morphology was compromised prior to 12 hours whether stored at RT or at 4 °C – 8 °C.Conclusion: This study provides evidence that blood samples stored in EDTA at 4 °C – 8 °C for seven days are suitable for testing on the ADVIA® 120 analyser for the FBC and percentage of reticulocyte parameters. However, storage at 4 °C – 8 °C is not a solution for samples referred for DIFF and PBS morphology review.

    Rapid regression of all symptoms was obtained after moderate chemotherapy in two women aged 69 and 77 years respectively with malignant non-Hodgkin's lymphomas. Cervico-facial locations of these tumors are discussed in relation to definition, etiology, geographic factors, genetic markers, and associated immunologic disorders. Diagnosis requires a series of explorations including, obviously as a last resort, exploratory cervicotomy. Other regions may be involved and must be investigated, but lesions not affecting lymph nodes occur in only approximately 2 p. cent of patients with cervico-facial malignant non-Hodgkin's lymphoma (approximately 10 p. cent of all malignant non-Hodgkin's lymphomas). Other localizations include the hard palate, gums, sinuses, and salivary glands. Burkitt's lymphoma represents, on the contrary, 30 p. cent of malignant non-Hodgkin's lymphoma seen in European children. The different therapeutic modalities available are discussed.

    Rationale: The aging population may strain intensive care unit (ICU) capacity and adversely affect patient outcomes. Existing fluctuations in demand for ICU care offer an opportunity to explore such relationships. Objectives: To determine whether transient increases in ICU strain influence patient mortality, and to identify characteristics of ICUs that are resilient to surges in capacity strain. Methods: Retrospective cohort study of 264,401 patients admitted to 155 U.S. ICUs from 2001 to 2008. We used logistic regression to examine relationships of measures of ICU strain (census, average acuity, and proportion of new admissions) near the time of ICU admission with mortality. Measurements and Main Results: A total of 36,465 (14%) patients died in the hospital. ICU census on the day of a patient’s admission was associated with increased mortality (odds ratio [OR], 1.02 per standardized unit increase; 95% confidence interval [CI]: 1.00, 1.03). This effect was greater among ICUs employing closed (OR, 1.07; 95% CI: 1.02, 1.12) versus open (OR, 1.01; 95% CI: 0.99, 1.03) physician staffing models (interaction P value = 0.02). The relationship between census and mortality was stronger when the census was composed of higher acuity patients (interaction P value < 0.01). Averaging strain over the first 3 days of patients’ ICU stays yielded similar results except that the proportion of new admissions was now also associated with mortality (OR, 1.04 for each 10% increase; 95% CI: 1.02, 1.06). Conclusions: Several sources of ICU strain are associated with small but potentially important increases in patient mortality, particularly in ICUs employing closed staffing models. Although closed ICUs may promote favorable outcomes under static conditions, they are susceptible to being overwhelmed by patient influxes. PMID:23992449

    Objective: To collect data on the consultation frequency and demographic profile of victims of violence attending an emergency department (ED) in Switzerland. Methods: We undertook screening of all admitted adult patients (>16 years) in the ED of the CHUV, Lausanne, Switzerland, over a 1 month period, using a modified version of the Partner Violence Screen questionnaire. Exclusionary criteria were: life threatening injury (National Advisory Committee on Aeronautics score ⩾4), or inability to understand or speak French, to give oral informed consent, or to be questioned without a family member or accompanying person being present. Data were collected on history of physical and/or psychological violence during the previous 12 months, the type of violence experienced by the patient, and if violence was the reason for the current consultation. Sociodemographic data were obtained from the registration documents. Results: The final sample consisted of 1602 patients (participation rate of 77.2%), with a refusal rate of 1.1%. Violence during the past 12 months was reported by 11.4% of patients. Of the total sample, 25% stated that violence was the reason for the current consultation; of these, 95% of patients were confirmed as victims of violence by the ED physicians. Patients reporting violence were more likely to be young and separated from their partner. Men were more likely to be victims of public violence and women more commonly victims of domestic violence. Conclusions: Based on this monthly prevalence rate, we estimate that over 3000 adults affected by violence consult our ED per annum. This underlines the importance of the problem and the need to address it. Health services organisations should establish measures to improve quality of care for victims. Guidelines and educational programmes for nurses and physicians should be developed in order to enhance providers' skills and basic knowledge of all types of violence, how to recognise and interact appropriately

    We conducted a systematic review and meta-analysis of anonymous surveys asking scientists whether they ever committed various forms of plagiarism. From May to December 2011 we searched 35 bibliographic databases, five grey literature databases and hand searched nine journals for potentially relevant studies. We included surveys that asked scientists if, in a given recall period, they had committed or knew of a colleague who committed plagiarism, and from each survey extracted the proportion of those who reported at least one case. Studies that focused on academic (i.e. student) plagiarism were excluded. Literature searches returned 12,460 titles from which 17 relevant survey studies were identified. Meta-analysis of studies reporting committed (N = 7) and witnessed (N = 11) plagiarism yielded a pooled estimate of, respectively, 1.7% (95% CI 1.2-2.4) and 30% (95% CI 17-46). Basic methodological factors, including sample size, year of survey, delivery method and whether survey questions were explicit rather than indirect made a significant difference on survey results. Even after controlling for these methodological factors, between-study differences in admission rates were significantly above those expected by sampling error alone and remained largely unexplained. Despite several limitations of the data and of this meta-analysis, we draw three robust conclusions: (1) The rate at which scientists report knowing a colleague who committed plagiarism is higher than for data fabrication and falsification; (2) The rate at which scientists report knowing a colleague who committed plagiarism is correlated to that of fabrication and falsification; (3) The rate at which scientists admit having committed either form of misconduct (i.e. fabrication, falsification and plagiarism) in surveys has declined over time.

    To assess the clinical and demographic profile of Systemic Inflammatory Response Syndrome (SIRS) and sepsis, among newly admitted children in different age groups in a hospital in North India. This prospective study was conducted at a referral care centre in Northern India. All children, age group 0 to SIRS) and sepsis and to gain clinical and demographic data. The criteria laid at International consensus conference, 2002, were used to define patients as SIRS, Sepsis, Severe sepsis and Septic shock. During the study period, a total of 865 patients were screened for SIRS. Prevalence of SIRS amongst hospitalised children was 23 % (n = 201). Seventy nine percent (n = 159) of patients had infection associated SIRS and 21 % (42) had non-infective SIRS. Sixty four percent (n = 129) SIRS patients had uncomplicated sepsis, 15 % (n = 30) patients fulfilled criteria for severe sepsis. Out of the latter 30, 19 had septic shock. Organ dysfunction in SIRS was noted in 25 % (n = 51). 37.25 % (n = 19) had multiple organ dysfunction syndrome (MODS). The most common organism isolated was Staphylococcus aureus (n = 9). Focus of infection in majority was pulmonary (44 %). Mean duration of antibiotic therapy and hospital stay in the SIRS group were 6.4 and 6.5 d respectively. In the group without SIRS, mean duration were 2.44 d and 3.07 d respectively The differences were statistically significant. In conclusion, the proportion of sepsis contributing to SIRS is high in a tertiary care hospital. Therefore rapid recognition of SIRS is essential. Goal directed treatment of sepsis is also important so that high mortality associated with severe sepsis and septic shock are prevented.

    Full Text Available Telomerase expression and telomere maintenance are critical for cell proliferation and survival, and they play important roles in development and cancer, including hematological malignancies. Transcriptional regulation of the rate-limiting subunit of human telomerase reverse transcriptase gen (hTERT is a complex process, and unveiling the mechanisms behind its reactivation is an important step for the development of diagnostic and therapeutic applications. Here, we review the main mechanisms of telomerase activation and the associated hematologic malignancies.

    The Waitemata Hypertension Clinic Database 2009-2012 (Auckland, New Zealand) was searched for patients meeting the definition of Malignant Hypertension. Eighteen of 565 patients met the criteria. All patients had essential hypertension which was either undiagnosed, untreated or undertreated. Most cases responded satisfactorily to standard drug therapy, but a number were left with significant chronic kidney disease. Malignant hypertension is a life-threatening disease which should be entirely preventable with regular blood pressure checks in primary care.

    Full Text Available Background: Tetanus remains one of the major public health hazards of the developing world. Mortality is much lower in the developed world because of the availability of facilities, unlike in most developing countries' Objectives: This study was aimed to determine the outcome of tetanus patients admitted in infectious disease unit of Rangpur Medical College Hospital. Methods: A total of 91 cases of tetanus patients were seen in the 18 month period with a mean of 5 cases per month; they are diagnosed and managed for tetanus in the medical wards from January 2011 to June 2012. The data were retrieved from their case records and analyzed. Results: There were thirty one deaths, accounting for an overall mortality of 34.16o.Total fifty six patients were cured among which sixteen (17.67% were cured with complication and four (4.4% patient were absconded. Mortality was high 45.84% (11 patients out of 24 ≥40 years age, whereas low 29.85 (20 patient out of 87 in <40 yea15 age (45.84% vs 29.85%. Mortality rate was also higher among female than male patients (34.66% vs 33.85%. Farmers experienced more death than non-farmer (4l.l8% vs 29-82%, P<0.05. Mortality was higher in patients who had not received any medical treatment for their wound than in patients who had received it for their wound (52.78% vs 21.81%, p<0.05. Patients with short incubation period of less than one week had higher mortality in comparison with those who had incubation period more than one week (53.33% vs 23.25%, P<0'05. Of the 91 patients, fifty six (64.34% were alive, though four remained in a persistent vegetative state due to tetanus toxin-induced brain damage and another two required a below knee amputation of the left leg. Hence, 40 were discharged well and 16 were discharged with permanent disabilities. Conclusion: The case fatality rate of tetanus has remained consistently high in the medical college. Factors that were significantly associated with high mortality included

    Full Text Available OBJECTIVE: Determine the effect that increased medical surgical (med/surg bed occupancy has on the time interval from admission order to arrival in the bed for the patients admitted from the emergency department (ED.METHODS: This retrospective observational study compares the total hospital bed occupancy rate and the medical surgical inpatient bed occupancy rate to daily averages for the time interval from admission order (patient posting for admission to the patient's arrival in the inpatient bed. Medical surgical inpatient bed occupancy of 92% was chosen because beyond that rate we observed more frequent extended daily transfer times. The data is from a single large tertiary care institute with 590 beds and an annual ED census of 80,000.RESULTS: Group 1 includes 38 days with (med/surg inpatient bed occupancy rate of less than 92%, with an average ED daily wait of 2.5 hrs (95% confidence interval 2.23-2.96 for transfer from the ED to the appropriate hospital bed.

Minimum daily average for the two groups was 1.2 hrs and 1.3 hrs, respectively. The maximum average was 5.6 hrs for group 1 and 8.6 hrs for group 2. Comparison of group 1 to 2 for wait time to hospital bed yielded p <0.01. Total reported hospital occupied capacity shows a correlation coefficient of 0.16 to transfer time interval, which indicates a weak relationship between total occupancy and transfer time into the hospital. Med/surg occupancy, the beds typically used by ED patients, has a 0.62 correlation coefficient for a moderately strong relationship.CONCLUSIONS: Med/surg bed occupancy has a better correlation to extended transfer times, and occupancy over 92% at 5 AM in our institution corresponds to an increased frequency of extended transfer times from the ED.

    Full Text Available Malignant pheochromocytoma (PCC is a rare condition. Although the liver is the second most frequent site of metastasis in malignant PCC, no definite treatments have been established. Herein, we report a case of liver metastasis of PCC that was successfully treated by transcatheter arterial chemoembolization (TACE. A 69-year-old man was admitted to the Department of Gastroenterology for evaluation of an incidental hepatic mass in August 2013. He had undergone right adrenalectomy in May 2005 and PCC had been confirmed on the basis of histopathological findings. Liver biopsy was performed, and metastatic PCC was diagnosed. The lesion appeared inoperable because of invasion of the portal vein and metastases in the lymph nodes along the hepatoduodenal ligament. Thus, TACE was performed instead. After TACE, symptoms including dizziness and cold sweating improved, and the patient's serum catecholamine levels decreased. On the basis of this case, we believe that TACE may be a useful treatment for liver metastasis in malignant PCC.

    Full Text Available The hematologic malignancies during pregnancy are rare and there is often a delay in diagnosis because of the similarity of symptoms to those of pregnancy. Therefore the management of disease necessitates many medical, psychological, social, and ethical problems for the patient and physician to deal with and a multidisciplinary approach of a medical team consisting of hematologist, obstetrician and pediatrician. Here, we present three cases of hematologic malignancies during pregnancy; acute myeloid leukemia, acute lymphoblastic leukemia, and B-cell non-Hodgkin’s lymphoma that were admitted to our clinic with different clinical presentation. There is a need for measures to increase the awareness of health workers related to hematologic malignancies during antenatal care.

    Serratia marcescens is a saprophytic gram-negative bacillus capable of causing a wide range of infections. A 57-year-old female was admitted to our hospital for four weeks with community acquired pneumonia. A chest x-ray, six weeks after discharge, demonstrated multiple, bilateral 'cannon ball'-like opacities and mediastinal lymphadenopathy which were highly suspicious of disseminated malignancy or tuberculosis. The only symptom that this patient had was a productive cough. She had multiple commodities, but no specific immunodeficiency disorder. Interestingly, her sputum and bronchial washing samples grew S. marcescens. The computed tomography-guided lung biopsy demonstrated necrotic granulomatous changes. There was no pathological evidence of tuberculosis or fungal infection, malignancy or vasculitis. There are only a handful of reported cases of Serratia granulomas. Thus, we are reporting a rare instance of pulmonary Serratia marcescens granuloma radiologically mimicking metastatic malignancy and tuberculosis infection.

    2012-06-01

    Full Text Available Abstract Background The tumorous infiltration or carcinosis of the pericardium could cause pericardial effusion in up to one-third of cases of malignancy, thus potentially interfere with the otherwise desirable oncological treatment. The existing surgical methods for the management of pericardial fluid are well-established but are not without limitations in the symptomatic relief of malignant pericardial effusion (MPE. The recurrence rate ranges between 43 and 69% after pericardiocentesis and 9 to 16% after pericardial drainage. The desire to overcome relative limitations of the existing methods led us to explore an alternative approach. Methods The standard armamentarium of the Carlens collar mediastinoscopy procedure was utilized in a Chamberlain parasternal approach of the pericardial sac. The laterality of approach was decided based upon the pleural involvement, as tumor-free pericardiopleural reflection is required. A pericardio-pleural window at least 3 cm in diameter was created. From January 2000 to December 2009, 22 cases were operated on with mediastinoscope-controlled parasternal fenestration (MCPF. Considering the type of the primary tumor, there were 11 lung cancer, 6 breast cancers, 2 haematologic malignancies and in 3 patients the origin of malignancy could not be verified. Results There were no operative deaths. We lost one patient (4.5% in the postoperative hospital period. All of the surviving patients had a minimum of 2 months of symptom-free survival. We detected transient recurrence of MPE in one patient (4.5% 14 days after the MCPF, which disappeared spontaneously after 24 hours. Conclusion The MCPF offers a real alternative in certain cases of pericardial effusion. We recommend this method especially for the definitive surgical palliation of MPE.

    Haemoglobinopathies constitute the commonest recessive monogenic disorders worldwide, and the treatment of affected individuals presents a substantial global disease burden. Carrier identification and prenatal diagnosis represent valuable procedures that identify couples at risk for having affected children, so that they can be offered options to have healthy offspring. Molecular diagnosis facilitates prenatal diagnosis and definitive diagnosis of carriers and patients (especially 'atypical' cases who often have complex genotype interactions). However, the haemoglobin disorders are unique among all genetic diseases in that identification of carriers is preferable by haematological (biochemical) tests rather than DNA analysis. These Best Practice guidelines offer an overview of recommended strategies and methods for carrier identification and prenatal diagnosis of haemoglobinopathies, and emphasize the importance of appropriately applying and interpreting haematological tests in supporting the optimum application and evaluation of globin gene DNA analysis.

    Cytology and cell biology are two separate fields that share a focus on cancer. Cancer is still diagnosed based on morphology, and surprisingly little is known about the molecular basis of the defining structural features. Cytology uses the smallest possible biopsy for diagnosis by reducing morphologic "criteria of malignancy" to the smallest scale. To begin to develop common ground, members of the American Society of Cytopathology Cell Biology Liaison Working Group classify some of the "criteria of malignancy" and review their relation to current cell biology concepts. The criteria of malignancy are extremely varied, apparently reflecting many different pathophysiologies in specific microenvironments. Criteria in Group 1 comprise tissue-level alterations that appear to relate to resistance to anoikis, alterations in cell adhesion molecules, and loss of apical-basal polarity. Criteria in Group 2 reflect genetic instability, including chromosomal and possibly epigenetic instability. Criteria in Groups 3 are subcellular structural changes involving cytoplasmic components, nuclear lamina, chromatin and nucleoli that cannot be accounted for by genetic instability. Some distinct criteria in Group 3 are known to be induced by cancer genes, but their precise structural basis remains obscure. The criteria of malignancy are not closely related to the histogenetic classification of cancers, and they appear to provide an alternative, biologically relevant framework for establishing common ground between cytologists and cell biologists. To understand the criteria of malignancy at a molecular level would improve diagnosis, and likely point to novel cell physiologies that are not encompassed by current cell biology concepts.

    Natural killer (NK) cells recognize and eliminate transformed or infected cells that have downregulated MHC class-I and express specific activating ligands. Recent evidence indicates that allogeneic NK cells are useful to eliminate haematological cancer cells independently of MHC-I expression. However, it is unclear if transformed cells expressing mutations that confer anti-apoptotic properties and chemoresistance will be susceptible to NK cells. Allogeneic primary human NK cells were activated using different protocols and prospectively tested for their ability to eliminate diverse mutant haematological and apoptotic-resistant cancer cell lines as well as patient-derived B-cell chronic lymphocytic leukemia cells with chemotherapy multiresistance. Here, we show that human NK cells from healthy donors activated in vitro with Epstein Barr virus positive (EBV+)-lymphoblastoid cells display an enhanced cytotoxic and proliferative potential in comparison to other protocols of activation such a K562 cells plus interleukin (IL)2. This enhancement enables them to kill more efficiently a variety of haematological cancer cell lines, including a panel of transfectants that mimic natural mutations leading to oncogenic transformation and chemoresistance (e.g., overexpression of Bcl-2, Bcl-XL and Mcl-1 or downregulation of p53, Bak/Bax or caspase activity). The effect was also observed against blasts from B-cell chronic lymphocytic leukemia patients showing multi-resistance to chemotherapy. Our findings demonstrate that particular in vitro activated NK cells may overcome anti-apoptotic mechanisms and oncogenic alterations frequently occurring in transformed cells, pointing toward the use of EBV+-lymphoblastoid cells as a desirable strategy to activate NK cells in vitro for the purpose of treating haematological neoplasia with poor prognosis.

    Background Knowledge of epidemiological data on skin diseases is important in planning preventive strategies in healthcare services. Objective To assess data from patients admitted to a triage dermatology clinic. Methods A retrospective study was performed of patients admitted over a one-year period to the Triage Dermatology Clinic at the Hospital das Clínicas of the University of São Paulo Medical School. Data were obtained from record books. The variables analyzed were: patient age, gender, dermatologic disease (initial diagnosis), origin (from where the patient was referred) and destination (where the patient was referred to). Results A total of 16,399 patients and 17,454 diseases were identified for analysis. The most frequent skin disorders were eczema (18%), cutaneous infections (13.1%), erythematous squamous diseases (6.8%) and malignant cutaneous neoplasms (6.1%). Atopic dermatitis was the most common disease in children. Acne was more common among children and adults, as were viral warts. Basal cell carcinoma and squamous cell carcinoma were more common in the elderly. Contact dermatitis and acne predominated in women. The most frequent origins were: the primary/secondary health system (26.6%), other outpatient specialties (25.5%), emergency care (14.9%); while the destinations were: discharged (27.5%), follow-up in our Dermatology Division (24.1%), return (14.1%) and the primary/secondary health system (20.7%). Conclusion Understanding the incidence of skin diseases is fundamental in making decisions regarding resource allocation for clinical care and research. Thus, we believe our findings can contribute to improving public health policies. PMID:27438199

    Full Text Available Analyses of haematological and biochemical constituents were carried out on the Norwegian subspecies of free-ranging red deer (Cervus elaphus atlanticus. All animals were captured from January to March by using a mixture of xylazine and tiletamin-zolazepam. Immobilisation was performed with plastic projectile syringes fired from a dart gun. Fourteen haematological parameters were analysed. There were no differences in the values between hinds and stags and between adults and calves (P > 0.01. Of the 22 biochemical compounds investigated there was a significant difference (P < 0.01 between calves and adults for lactate dehydrogenase (LD, globulin, beta globulin, gamma globulin, and the minerals Na, K, Mg, Zn, Ca, and P. Differences (P < 0.01 between hinds and stags were found in cholesterol, gamma glutamyl transferase (GGT, alpha-1 globulin, alpha-2 globulin and Cu. The blood values determined in this study can be used as reference values for this red deer subspecies immobilised with a mixture of xylazine-tiletamin-zolazepam for health control and diagnosis of diseases.Abstract in Norwegian /Sammendrag:Hematologiske og biokjemiske parametere er analysert på norsk frittlevende hjort (Cervus elaphus atlanticus.

    The outcome of mechanically ventilated patients initially denied admission to an intensive care unit (ICU) and subsequently admitted is unclear. We compared outcomes of patients denied ICU admission and subsequently admitted, to those of patients admitted to the ICU and to patients refused ICU admission. The medical records of all the patients who were subjected to mechanical ventilation for at least 24h over a 4year period (2010-2014) were reviewed. Of 707 patients (757 admissions), 124 (18%) were initially denied ICU admission and subsequently admitted. Multivariate stepwise logistic regression analysis showed significant association with death of: age, length of stay, nursing home residency, duration of mechanical ventilation, previous admission with mechanical ventilation, cause for mechanical ventilation, rate of failed extubations, associated morbidity (previous cerebrovascular accident, dementia, chronic renal failure), and occurrence of nosocomial bacteremia. The odds for death among patients denied ICU admission and subsequently transferred to the ICU compared to patients admitted directly to the ICU was 3.6 (95% CI: 1.9-6.7) (Padmission compared to those who were initially denied and subsequently admitted were not statistically significant (OR=1.7, 95% CI: 0.8-3.8). In conclusion, patients denied ICU admission and subsequently admitted face a considerable risk of morbidity and mortality. Their odds of death are nearly three times those admitted directly to the ICU. Late admission to the ICU does not appear to provide benefit compared to patients who remain in general medicine wards.

    2007-02-01

    In 2005, 13.5% of clinic-admitted raptors in northern Colorado tested positive for West Nile virus (WNV). Clinic-admitted-raptor surveillance detected WNV activity nearly 14 weeks earlier than other surveillance systems. WNV surveillance using live raptor admissions to rehabilitation clinics may offer a novel surveillance method and should be considered along with other techniques already in use.

    2017-10-01

    Bornaviruses are considered to be the causative agent of proventricular dilatation disease (PDD) in psittacine birds. In order to detect haematological and blood chemistry changes during the development of PDD and a possible correlation with clinical signs and the virological status, six African grey parrots (Psittacus erithacus) were experimentally infected with parrot bornavirus 4 (PaBV-4) by subcutaneous route. All six parrots developed clinical signs of varying extent and successful infection was confirmed in all the birds by seroconversion or detection of RNA of the PaBV-4 infection strain. Based on population-based and intra-individual reference ranges established during 12 months prior to experimental infection, only minor haematological changes were detected in individual birds after infection. Changes in blood chemistry were restricted to aspartate aminotransferase, creatine kinase, total protein, glucose and uric acid. Plasma protein electrophoresis revealed marked changes starting 10 weeks post infection characterized by an increase in the γ-globulin fraction and a gradual decrease to normal values during weeks 22-34. Indications of an acute-phase reaction at the initial stages of infection were not detected. While three birds suffered from clinical signs of PDD, which included weight loss and neurological disorders and died before development of haematological and plasma protein changes, recovery of clinical disease was paralleled in the remaining birds by an increase in γ-globulins and bornavirus-specific antibody titres.

    Full Text Available It is established that haematological and biochemical parameters provide important data to assess the physiological condition and health status of wild birds. To undertake conservation physiology or ecophysiology work, it is therefore essential to establish baseline physiological parameters and how these parameters change with age and life history events. In this work, we determined and compared baseline haematology and serum biochemistry between adults and chicks of three Antarctic penguin species of the genus Pygoscelis: gentoo (P. papua, Adélie (P. adeliae and chinstrap (P. antarcticus. Differences in adults among species were observed in haemoglobin and biochemical parameters such as total proteins, glucose and alkaline phosphatase activity. In addition, differences between adults and chicks in haematocrit, haemoglobin, total proteins and glucose concentration were determined. Moreover, we evaluated the electrophoretic protein profiles between adults and chicks of the genus Pygoscelis, and a conserved protein pattern was observed among species and ages in the genus. Altogether, the results suggest that biochemical and haematological differences among pygoscelids may be related to the nutritional status and energetic expenditure during breeding as well as their feeding habits and development stage.

    Full Text Available Aim : To study the influence of housing system and dietary supplementation of probiotics and enzymes on haematological parameters of rabbits. Materials and Methods: A total of 144 weaned rabbits were divided into 2 groups of 72 in each group and housed under conventional cage system and backyard system. The rabbits in each housing system were divided into 4 groups of 18 in each group and the diets were supplemented with probiotics, enzymes and both. Results: The housing system and supplementation of probiotics and enzymes did not exert significant influence on any of the haematological parameters studied. However, there was slight positive influence of probiotic and enzyme supplementation on the health status of rabbits as revealed by haematological parameters. The overall mean Total erythrocyte count, total leucocyte count, lymphocytes, neutrophils, eosinophils, monocytes, haemoglobin and packed cell volume were 7.52, 6.29 (103/mm3, 60.27%, 35.71%, 1.35%, 1.92%, 10.67 g/dl and 34.25%, respectively. Conclusion: Rabbits can be reared on low input backyard system without any adverse effect on health and supplementation of probiotics and enzymes had a positive influence on health status of rabbits.

    Pregnancy is a physiological phenomenon. However, some women develop problems during pregnancy period, which puts both the mother's and the foetus health at risk. Hypertensive disorders of pregnancy are the type of the maternal diseases that can cause the most detrimental effects to the mother and foetus. To determine the haematological parameters in neonates born to preeclamptic mothers. It was a prospective case control study carried out on neonates born to preeclamptic mothers in our institute from March 2016 to November 2016. All the haematological parameters of the neonates were recorded and analyzed using SPSS 22.0 version software. Mean, Standard deviation, minimum and maximum values were calculated for continuous variables. The difference between the two groups was compared using independent student 't' test. The p-value out of which 60 were of study group and 60 of control group. Mean hemoglobin, PCV, red cell count, Mean Corpuscular Volume (MCV), reticulocyte count and nRBC were significantly increased pborn to preeclamptic mothers. No difference was found between the two groups in the Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) value p(>0.05). The babies born to preeclamptic mothers are more prone for development of prematurity, low birth weight, Intrauterine Growth Retardation (IUGR), sepsis, neutropenia, leucopenia, thrombocytopenia, increased RBC count, nRBC and reticulocyte count. Early haematological screening helps to decrease morbidity, improve growth, development and survival of the baby.

    The study was conducted to investigate the effects of feeding different levels of dried cassava leaves at 0%, 20%, 40% and 60%, respectively, using guinea grass as basal feed, on the haematological and serum biochemical parameters of West African Dwarf (WAD) goats. The study lasted for 116 days during which haematological and serum biochemical parameters were monitored in 40 male goats before and after, using a completely randomized design. At the start of the experiment, packed cell volume (PCV) ranged from 21.5% to 25.5% while haemoglobin concentration (Hb) and RBC significantly (P diets. At the end of the trial, there was a slight increase in the values of PCV and Hb in the diets (P > 0.05). Lymphocyte reduced significantly (P diets. Neutrophils, however, increased (P > 0.05) at the 0% to 40% levels and reduced at the 60% level of dried cassava leaves inclusion. At the start of the experiment, values for glucose significantly (P diets. The study revealed that inclusion of dried cassava leaves in the diets of West African Dwarf goats had no deleterious effects on the haematological and serum biochemical parameters of WAD goats and could therefore be included in ruminant diets up to 60%.

    Two cases of XYY male with refractory anemia with excess of blasts are reported, and previous reported XYY males with hematologic malignancy are reviewed. Altogether 26 cases were collected for analysis: acute myeloid leukemia (10), acute lymphocytic leukemia (seven), acute leukemia (two), chronic myelocytic leukemia (three), myelodysplastic syndrome (three), and essential thrombocythemia (one). The age at the time of diagnosis ranged in age from 7.5 to 81 years. In three of six XYY/XY mosaicism cases, XYY clone was associated with malignancy. However, in two cases XYY clone was not involved. The evidence presented here suggests that the event of an XYY male with hematologic malignancy is incidental rather than a genetic etiology.

    We report a very rare and successful surgery for primary malignant tumor of the sternum. A 73-year-old male, previously healthy, was admitted to our hospital because a chest computed tomography scan detected an abnormal shadow that suggested a sternal tumor destroying part of the sternum body. Aspiration needle biopsy demonstrated a primary sternal chondrosarcoma measuring 3 x 4 cm in diameter. The sternum below the second intercostal space was resected along with a 1-cm width of cartilage below the third rib on each side. Sternal reconstruction was performed with Composix mesh, titanium mesh, and Marlex mesh, using a right pectoralis major muscle flap translation. The patient was extubated just after surgery, and the postoperative course was uneventful. This procedure may be useful for repairing the detect after wide sternotomy.

    With surgery for hepatic malignancy, there are poor options for chemotherapy; many patients are deemed unresectable because of vascular involvement or location of tumors. Over the past few decades, advances in surgical technique have allowed resection of these tumors with vascular reconstruction to achieve negative margins and improve chances for survival. This article reviews those reconstruction techniques and outcomes in detail, including in situ perfusion and ex vivo liver surgery, and provides a discussion of implications and operative planning for patients with hepatic malignancy in order to provide surgeons with better understanding of these complicated operations.

    2015-01-01

    Full Text Available Deciduosis classically occurs in the context of known endometriosis in the pelvis, most commonly in the ovaries, but also in the peritoneum. However, ovarian deciduosis outside the context of endometriosis is rare and makes diagnosis difficult, especially as the sonographic appearance suggests a malignant process. We report a case of decidualized ovarian mass in a patient without prior history of endometriosis that mimicked an ovarian malignancy. MRI may be a useful imaging modality to monitor these lesions and guide management. Consultation with a multidisciplinary team accustomed to such conditions will help to tailor the management to each individual.

    2007-01-01

    Full Text Available Introduction Suicide is a conscious and intentional destruction of one’s own life, which occurs as a result of mutual influence of a person’s disposition and motives (facts inspiring the commitment of suicide. It is well known that various diseases, including malignancies, could be important and in some cases the only motive for committing suicide. Objective The purpose of the study was to analyze in detail suicides of persons whose only motive was an established malignant disease. Method The analysis was performed using the autopsy material of the Institute of Forensic Medicine, School of Medicine, University of Belgrade, during the period from 1990 to 2004. The reports on performed medico-legal autopsies were used, as well as history data obtained from the family members of suicidal persons, investigation reports and the available medical documents. Results In 1931 cases there was established suicidal nature of a violent death. Neoplasms were the suicidal motive in 37 persons (1.9%. The basic characteristics of the analyzed sample were predominance of males (26:11, ratio 2.4:1, the age of over 70 years and the highest incidence of malignant lung and breast tumors. Almost all cases were the persons who underwent treatment for malignant neoplasms over a longer period of time. During 19 autopsies (51.3% out of 37, a progressive phase of malignancy was established, i.e. metastases. The data on prior oral announcement of suicide intention were obtained for 70.3% (26 cases, and on previous suicidal attempts only for 13.5% (5 cases. In the majority of cases (78.4% the place of committed suicide was the person’s home. In 16 cases (43.2% the suicide was committed with a firearm. Hanging as a manner of destroying one’s own life was chosen by 12 persons (32.4%, while other ways were less frequently used. Conclusion Although malignancies were not present with high incidence as a suicidal motive in our analyzed sample, such cases require particular

    Full Text Available The aim of the study was to investigate the effect of Ascophyllum nodosum, an edible brown macroalga, on some haematologic parameters of dairy cows. Nineteen clinically healthy Holstein cows, an average 4.3 years old, were divided into two groups for 49 days. Ten cows received control diet (roughages and concentrate while the concentrate of 9 cows was additionally supplemented with 80 g A. nodosum/cow/day. Average daily milk production (controls 39.6 kg/cow; A. nodosum 40.2 kg/cow, milk protein and fat were not affected by the alga supplementation. Glucose, sorbitol dehydrogenase, haemoglobin, haematocrit and white/red blood cells were evaluated in weekly blood samples. It was seen that A. nodosum increased blood glucose and decreased sorbitol dehydrogenase compared to controls, without any adverse effects on the other examined parameters. Consequently, A. nodosum may be suggested as a functional ingredient in dairy cow nutrition, improving energy utilization and expressing hepatoprotective effect.

    The objective is to determine any possible differences between haematological, biochemical and bone mineral density in vegetarians (vegans and lacto-ovovegetarians) and non-vegeterians. The examined group consisted of 100 individuals: 50 non-vegetarians and 50 vegetarians. The vegetarian group was further divided in 2 subgroups: 20 vegans and 30 lacto-ovovegetarians. In all participants, plasma levels of erythrocytes, haemoglobin, haematocrit, iron, low density lipoprotein, (LDL), high density lipoprotein (HDL) total cholesterol, triglycerides and glucose were measured. Quantitative ultrasound parameters of the right calcaneus were determined in all participants. The results showed that lacto-ovovegetarians had statistically significantly higher red blood cell counts and haematocrit values than non-vegetarians. Vegans also had higher haematocrit values than non-vegetarians. Statistically significant differences were found between iron plasma levels in the examined groups. Iron levels were lower in non-vegetarians than in vegans and lacto-ovovegetarians. Non-vegetarians had much higher levels of cholesterol, triglycerides and LDL than the other two groups, but there were no differences found between same values in vegans and lacto-ovovegetarians. A well planned and balanced vegetarian diet, with avoidance of risk factors, does not result in abnormalities in laboratory tests and bone status parameters.

  16. Life-threatening haematological complication occurring in a cat after chronic carbimazole administration

    2016-09-01

    Full Text Available Case summary An 11-year-old spayed female domestic shorthair cat with a history of hyperthyroidism treated with carbimazole for 7 months was presented for a check-up after a few episodes of vomiting. The cat had been receiving prednisolone at 0.5 mg/kg PO q12h for recent pancreatitis and concurrent inflammation of liver and small intestines confirmed by biopsies. Clinical examination revealed pale mucous membranes with a capillary refill time of 120 s and fibrinogen serum concentration (3.5 g/l. Morphological changes of thrombocytes in the absence of thrombocytopenia were also noted. In-saline agglutination test was positive. Abdominal radiographic and ultrasonographic examinations excluded the presence of organ abnormalities and peritoneal effusion. Blood biochemistry was unremarkable. Feline leukaemia virus and feline immunodeficiency virus tests were negative. On the basis of these findings, immune-mediated anaemia secondary to chronic carbimazole administration was suspected. Prednisolone was increased to 2 mg/kg PO q24h and carbimazole tablets were stopped. Despite close monitoring and intensive care, the cat died the same evening of admission to the hospital. Relevance and novel information This report suggests that severe haemotoxicity may occur as a sequel of chronic carbimazole administration in cats. Routine bloodwork and accurate follow-up of cats under treatment with thyrotoxic therapy may be advisable, in order to detect haematological changes before lethal complications occur.

    The Atlas of Genetics and Cytogenetics in Oncology and Haematology (http://AtlasGeneticsOncology.org) is a peer-reviewed internet journal/encyclopaedia/database focused on genes implicated in cancer, cytogenetics and clinical entities in cancer and cancer-prone hereditary diseases. The main goal of the Atlas is to provide review articles that describe complementary topics, namely, genes, genetic abnormalities, histopathology, clinical diagnoses and a large iconography. This description, which was historically based on karyotypic abnormalities and in situ hybridization (fluorescence in situ hybridization) techniques, now benefits from comparative genomic hybridization and massive sequencing, uncovering a tremendous amount of genetic rearrangements. As the Atlas combines different types of information (genes, genetic abnormalities, histopathology, clinical diagnoses and external links), its content is currently unique. The Atlas is a cognitive tool for fundamental and clinical research and has developed into an encyclopaedic work. In clinical practice, it contributes to the cytogenetic diagnosis and may guide treatment decision making, particularly regarding rare diseases (because they are numerous and are frequently encountered). Readers as well as the authors of the Atlas are researchers and/or clinicians.

    In the international literature, the most commonly recommended intervention for managing oral mucositis is good oral care, assuming that nurses have sufficient knowledge and skills to perform oral care correctly. The aim of the present study was to investigate if knowledge and skills about oral care improve when education in oral care is provided to nurses in charge of patients who are at risk of oral mucositis. This intervention study consists of a baseline test on the knowledge and skills of nurses of the haematology wards of two different hospitals. Oral care education sessions were given in one hospital and follow-up tests were performed in both hospitals. Nursing records were examined and observations of nurses performing oral care were made at baseline as well as at follow-up. The results show significant differences in the scores for knowledge and skills before and after the education, whereas there was no difference in scores at the two points in time for the comparison hospital, where no education had taken place. The records test showed no differences at baseline or follow-up for the two groups. Observations showed that nurses who followed the education session implemented the oral care protocol considerably better than those who did not attended. Education in oral care has a positive influence on the knowledge and skills of nurses who care for patient at risk of oral mucositis, but not on the quality of oral care documentation.

    Oxidative stress has been correlated with pathologies that impair the performance of athlete horses. The aim of this study was to assess the effects of supplementation with a mixture of polyunsaturated oil and vitamin E on the antioxidant and haematological biomarkers of horses. Horses under maintenance care (n = 6) and horses in training (n = 10) received 100 and 300 ml of the oil mixture respectively. Supplementation was provided for a period of 8 weeks, together with isocaloric inclusion. Blood samples were collected at three time periods (pretest, after 4 weeks and after 8 weeks) to analyse the following: the red blood cell count (RBCc); haemoglobin (Hb); haematocrit (HT); leucocytes; lymphocytes; platelets; the mean corpuscular volume (MCV); the mean corpuscular haemoglobin concentration (MCHC); the standard deviation of the red blood cell distribution width (RDW-SD); the coefficient of variation of the red blood cell distribution width (RDW-CV); glutathione peroxidase (GPx); superoxide dismutase (SOD); uric acid (UrAc); total plasma proteins (TPP); and creatine kinase (CK). After the 8 weeks of supplementation, animals under maintenance care exhibited significant increases in SOD, UrAc, the white blood cell count (WBCc), the RDW-SD and the RDW-CV (p supplementation with polyunsaturated oil and vitamin E increases blood antioxidants among animals under maintenance and in training, with different trends, while contributing to the fight against oxidative stress in each group analysed.

    Pharmaceuticals are used extensively in human and veterinary medicine to eradicate or prevent diseases. The residues of these drugs have been detected in aquatic ecosystem; nevertheless, their toxicological effects on Clarias gariepinus have not been critically investigated. In this study, the toxic effects of diclofenac (DCF), a non-steroid anti-inflammatory drug, were studied in C. gariepinus by acute and chronic static renewable bioassay. The 96 h LC50 of DCF to C. gariepinus was 25.12 mg/L. Exposure to acute toxicity resulted in abnormal behavior and mortality of some fish. Compared with the control, chronic exposure of the fish to concentration (1.57, 3.14 and 6.28 mg/L) showed significantly higher mean corpuscular haemoglobin concentration (MCHC), mean corpuscular volume (MCV) and white blood cell (WBC), with significantly lower haemoglobin (Hb), haematocrit, red blood cell (RBC) and mean corpuscular haemoglobin (MCH) with increase in the concentration of the drug. Furthermore, the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and glucose values significantly increased while protein levels were reduced (p < 0.05) in serum and gills throughout the 42-day exposure period. The study reports that DCF-induced enzymatic and haematological changes in the fish and recommends that these parameters be used as potential biomarkers for assessing residual pharmaceuticals available in aquatic ecosystem.

    Full Text Available This study investigated the effect of chloroacetic acid on growth performance and heamatological parameters of weanling pigs. Thirty-six cross-bred weanling pigs (Landrace × Duroc were allotted randomly to four treatment groups, with three replicates of three weanling pigs in each group. Control (T1 weanling pigs were given a standard basal diet; Treatment 2, 3 and 4 were diets of 0.3, 0.6 and 0.9 percents levels of inclusion of chloroacetic acid respectively. After six weeks, blood and intestinal samples were collected from one animal per replicate. Data on feed intake and weight gain were collected daily. Results showed that chloroacetic acid did improve the animal growth performance. There was a decrease in pH. There was significant differences (P<0.05 on white blood cell and mean corpuscular haemoglobin across the treatment. There was no significant difference (P<0.05 across the treatments on pack cell volume and red blood cell count. This study showed that chloroacetic acid influenced some haematological parameters, decreased the pH of the gastro-intestinal tract of the animals. Further studies will be needed to better understand the mechanisms underlying the effects observed when chloroacetic acid is fed to weanling pigs.

    To investigate the effects ofMoringa oleifera leaf meal (MOLM) on the performance and haematology of broiler finisher using 120 Cobb chicks of 4 weeks old broiler chicks. The birds were assigned randomly into four dietary treatments containing MOLM at 0, 6%, 8%, and 10% (treatments 1, 2, 3 and 4) inclusion levels, respectively, in a complete randomized design experiment. The effect of the dietary treatments on the growth performance and blood parameters of the broiler finisher was determined. MOLM at a rate of 6% (T2), 8% (T3), and 10% (T4) of the diets (as fed basis) to replace 3.2%, 5.6% and 8.6% of the crude protein (CP) of the control diet. The daily feed, dry matter and CP intake of the chicks fed MOLM diets were higher (p0.05) among treatments. The results indicated that at 10% in the diets of broiler finisher chick, MOLM could be substituted with expensive conventional protein sources without any deleterious effects on performance and blood parameters of broiler finisher chicken.

    Full Text Available Broiler is consumed by human population in large quantities. Its brooding conditions are very important due to their linkage with the financial impacts involved in poultry industry. These brooding conditions are not only vital due to economic reasons but also extremely important due to health impacts on chickens and human population being terminal consumers. As (III presence in the drinking water is resulted in bio-accumulation in chicks being brooded under otherwise similar conditions except drinking water. This bio-accumulation disturbs the eco-physiological and blood parameters. Haematological studies of anti-coagulated and serum blood samples core parameters reveals that As (III contamination in drinking water is the significant source of adverse disturbance of blood parameters of red blood cell, white blood cell, hemoglobin, packed cell volume, sodium, calcium, potassium ions, albumin, urea, creatinine and cholesterol, with a highly significant p value of less than 0.01 after 14th brooding day with bio-accumulation of 25.8 µg/L of As (III in blood samples

    Full Text Available Parachanna obscura popularly called snakehead, a fresh water teleost belonging to the family channidae, is highly predatory no wonder it is adopted in Tilapia population. Its high quality flesh together with its good taste made it high priced fish in the local markets and hence improved its commercial and aquacultural potentials. Previous studies on the biology of the fish were concentrated on its food and feeding habits as well as age and growth. Information on its haematological characteristics is non-existent. The blood characteristics determined were leucocytes and erythrocytes count heamoglobin concentration and packed cell volume. Blood indices which include Mean Cell Heamoglobin Concentration (MCHC, Mean Corpuscular Haemoglobin (MCH, Mean Corpuscular Volume (MCV and Erythrocyte Sedimentation Rate (ESR were determined. There was no positive correlation between the physical parameters of length and weight, the leucocytes and erythrocyte counts. However significant and positive correlation existed among the haemoglobin concentration and the packed cell volume. The influence of stress due to capture, transportation, sampling age and sex on the heamatological characteristics of the fish were discussed establishment of the heamatological characteristics of P. obscura will help to determine the health status and provide basic information and data for comparative heamatological studies with other fish species as well as disease, toxicological and parasitological investigations.

    Peptide receptor radionuclide therapy (PRRT) has become an important treatment option in the management of advanced neuroendocrine tumours. Long-lasting responses are reported for a majority of treated patients, with good tolerability and a favourable impact on quality of life. The treatment is usually limited by the cumulative absorbed dose to the kidneys, where the radiopharmaceutical is reabsorbed and retained, or by evident haematological toxicity. The aim of this study was to evaluate how renal function affects (1) absorbed dose to the kidneys, and (2) the development of haematological toxicity during PRRT treatment. The study included 51 patients with an advanced neuroendocrine tumour who received {sup 177}Lu-DOTATATE treatment during 2006 - 2011 at Sahlgrenska University Hospital in Gothenburg. An average activity of 7.5 GBq (3.5 - 8.2 GBq) was given at intervals of 6 - 8 weeks on one to five occasions. Patient baseline characteristics according to renal and bone marrow function, tumour burden and medical history including prior treatment were recorded. Renal and bone marrow function were then monitored during treatment. Renal dosimetry was performed according to the conjugate view method, and the residence time for the radiopharmaceutical in the whole body was calculated. A significant correlation between inferior renal function before treatment and higher received renal absorbed dose per administered activity was found (p < 0.01). Patients with inferior renal function also experienced a higher grade of haematological toxicity during treatment (p = 0.01). The residence time of {sup 177}Lu in the whole body (range 0.89 - 3.0 days) was correlated with grade of haematological toxicity (p = 0.04) but not with renal absorbed dose (p = 0.53). Patients with inferior renal function were exposed to higher renal absorbed dose per administered activity and developed a higher grade of haematological toxicity during {sup 177}Lu-DOTATATE treatment. The study confirms the

    Full Text Available Background: Pleural fluid cytology for malignant cells is the easiest way to diagnose malignant pleural effusion with good sensitivity and specificity. With the introduction of medical thoracoscopy, the use of closed pleural biopsy for the diagnosis of cytology negative malignant pleural effusion is gradually decreasing. However use of thoracoscopy is limited due to its high cost and procedure related complications. Aims: The aim was to assess the usefulness of closed pleural biopsy in the diagnosis of malignant pleural effusion. Materials and Methods: Sixty-six patients of pleural effusion associated with malignancy were selected from the patients admitted in the chest ward of a tertiary care hospital over a period of 1 year. Pleural fluid aspiration for cytology and closed pleural biopsy were done in all the patients. Results: Out of 66 patients, 46 (69% patients showed malignant cells in pleural fluid cytology examination. Cytology was positive in 35 (52%, 10 (15%, and 1 (1.5% patients in the first, second, and third samples respectively. Closed pleural biopsy was positive in 32 (48% patients. Among them, 22 also had positive cytology. Additional 10 cytology negative patients were diagnosed by pleural biopsy. Cytology-histology concordance was seen in 12 patients. Definite histological diagnosis could be achieved in five patients with indeterminate cytology. Pleural biopsy was not associated with any major postoperative complication. Conclusion: Closed pleural biopsy can improve the diagnostic ability in cytology negative malignant pleural effusion. Closed pleural biopsy has still a place in evaluation of malignant pleural effusion especially in a resource-limited country like India.

    An important, but not well characterized, population receiving intermediate care is that of medical patients admitted directly from the emergency department. To characterize emergency medical patients and their outcomes when admitted to an intermediate care unit with clearly defined admission guidelines. Demographic data, admitting diagnoses, illness severity, comorbid conditions, lengths of stay, and hospital mortality were characterized for all emergency medical patients admitted directly to an intermediate care unit from July through December 2012. A total of 317 unique patients were admitted (mean age, 54 [SD, 16] years). Most patients were admitted with respiratory (26.5%) or cardiac (17.0%) syndromes. The mean (SD) Acute Physiology and Chronic Health Evaluation score version II, Simplified Acute Physiology Score version II, and Charlson Comorbidity Index were 15.6 (6.5), 20.7 (11.8), and 2.7 (2.3), respectively. Severity of illness and length of stay were significantly different for patients who required intensive care within 24 hours of admission (n = 16) or later (n = 25), patients who continued with inter mediate care for more than 24 hours (n = 247), and patients who were downgraded or discharged in less than 24 hours (n = 29). Overall hospital mortality was 4.4% (14 deaths). Emergency medical patients with moderate severity of illness and comorbidity can be admitted to an intermediate level of care with relatively infrequent transfer to intensive care and relatively low mortality. ©2016 American Association of Critical-Care Nurses.

    We report 2 cases of pulmonary sarcomatoid carcinoma mimicking malignant mesothelioma. Case 1: A 69 year-old man presented, complaining of right chest pain. The chest X ray film and CT showed tumors in the right chest wall and pleura. Histological findings of specimens obtained from a percutaneous biopsy revealed spindle tumor cells, and the immunohistochemistry showed that the tumor cells were positive for CK-7, AE1/AE3, and vimentin and negative for calretinin, D2-40, and WT-1. We diagnosed pulmonary sarcomatoid carcinoma and started chemotherapy with carboplatin and paclitaxel, but it was ineffective. Case 2: A 68 year-old man was admitted complaining of general malaise. The chest X ray film and CT revealed tumors in the right chest wall. Histological findings showed necrosis and spindle tumor cells which were positive for AE1/AE3 and vimentin, and negative for calretinin, D2-40, and WT-1. We diagnosed pulmonary sarcomatoid carcinoma and started chemotherapy with carboplatin and paclitaxel. However the disease continued to progress and he died 2 months after admission. The pulmonary sarcomatoid carcinoma was reported to have spred to the pleural and chest wall. The present two cases showed prominent chest wall and pleural tumors with obscure primary lung tumors. Therefore, we needed to differentiate sarcomatoid carcinoma from malignant pleural mesothelioma.

    Full Text Available Phyllodes tumors (PTs account for <3% of fibroepithelial breast lesions and for 0.3% to 1.0% of primary breast tumors. They occur predominantly in middle-aged women (mean age range, 40–50 years. PTs can be categorized into benign, borderline, and malignant; the first 2 categories are distinguished only by degree of cellular atypia and mitotic activity. Malignant PTs are more frequent among persons of Hispanic ethnicity, especially those born in Central America or South America. Heterologous sarcomatous elements may be present in malignant PTs, predominantly liposarcoma and rarely fibrosarcoma, rhabdomyosarcoma, leiomyosarcoma, osteosarcoma, and chondrosarcoma. Breast angiosarcoma (BA is a rare heterologous, sarcomatous element that may arise secondary to malignant PT. We report a 47-year-old woman with no history of previous surgery or radiation therapy who presented to the emergency department with a painful right breast mass. She admittedly noticed the right breast mass for many years; however, recently it increased in size. Mammography and ultrasonography identified a partially cystic mass. Core needle biopsy showed dense hyalinized fibrous tissue with old blood clots, suggestive of infarcted fibroadenoma. The patient received antibiotics and analgesics; however, she reported intractable pain and a worsening skin rash of her right breast. Chest computed tomography and magnetic resonance imaging showed a doubling in mass size, with pectoralis major muscle involvement. Incisional biopsy showed malignant PT with heterologous high-grade angiosarcoma. The diagnosis of angiosarcoma was confirmed through immunoreactivity for CD31, FLI1, and ERG immunostains.

Patients was diagnosed as malignant ascites with multicentric hepatoma with abdominal lymphodenopathy, lung, liver and vertebral body metastasis and left portal vein thrombosis. Patient was managed with temporary external paracentesis (pigtail catheter and oral furosemide 40 mg daily and spironolactone 100 mg daily. Although abdominal paracentesis, diuretics and peritoneovenous shunting are commonly used procedures in management of malignant ascites, there are no randomized controlled trials evaluating the efficacy and safety of these therapies.

    Full Text Available Malignant mesothelioma is a rare malignancy of the body cavities with dismal prognosis. It has been a diagnostic dilemma for years with many clinical and pathological mimics. Discovery of a reliable tumour marker will definitely be of value in screening individuals with a history of asbestos exposure, diagnosis, treatment and follow up of malignant mesothelioma. Many tumour markers have been studied and speculatively associated with the malignant mesothelioma, but much still needs to be proven.

    Full Text Available The use of simple and economic tests to rule out diseases of sufficient clinical severity is appealing in emergency department (ED, since it would be effective for contrasting ED overcrowding and decreasing healthcare costs. The aim of this study was to assess the diagnostic performance of simple and economic haematological testing in a large sample of adult patients presenting at the ED of the Academic Hospital of Parma during the year 2010 with the five most frequent acute pathologies (i.e., acute myocardial infarction, renal colic, pneumonia, trauma and pancreatitis. Both leukocyte count and hemoglobin showed a good diagnostic performance (Area Under the Curve [AUC] of 0.85 for leukocyte count and 0.76 for hemoglobin; both p < 0.01. Although the platelet count was significantly increased in all patients groups except pancreatitis, the diagnostic performance did not achieve statistical significance (AUC 0.53; p = 0.07. We also observed an increased RDW in all groups, except in those with trauma and the diagnostic performance was acceptable (AUC 0.705; p < 0.01. The mean platelet volume (MPV was consistently lower in all patients groups and also characterized by an efficient diagnostic performance (AUC 0.76; p < 0.01. This evidence led us to design an arbitrary formula, whereby MPV and hemoglobin were multiplied, and further divided by the leukocyte count, obtaining a remarkable AUC (0.91; p < 0.01. We conclude that simple, rapid and cheap hematological tests might provide relevant clinical information for decision making to busy emergency physicians, and the their combination into an arbitrary formula might further increase the specific diagnostic potential of each of them.

    The tolerance and effects of nitrite on ion balance and haematology were investigated in the striped snakehead, Channa striata Bloch 1793, which is an air-breathing fish with reduced gills of importance for aquaculture in South East Asia. C. striata was nitrite tolerant with a 96 h LC50 of 4.7 mM. Effects of sub-lethal exposures to nitrite (0mM, 1.4mM, and 3.0mM) were determined during a 7-day exposure period. Plasma nitrite increased, but the internal concentration remained well below ambient levels. Extracellular nitrate rose by several mM, indicating that a large proportion of the nitrite taken up was converted to nitrate. Nitrite reacted with erythrocyte haemoglobin (Hb) causing methaemoglobin (metHb) to increase to 30% and nitrosylhaemoglobin (HbNO) to increase to 10% of total Hb. Both metHb and HbNO stabilised after 4 days, and functional Hb levels accordingly never fell below 60% of total Hb. Haematocrit and total Hb were unaffected by nitrite. Although the effects of nitrite exposure seemed minor in terms of plasma nitrite and metHb increases, ion balance was strongly affected. In the high exposure group, total osmolality decreased from 320 mOsm to 260 mOsm, and plasma sodium from 150 mM to 120 mM, while plasma chloride fell from 105 mM to 60mM and plasma bicarbonate rose from 12 mM in controls to 20mM in exposed fish. The extreme changes in ion balance in C. striata are different from the response reported in other fish, and further studies are needed to investigate the mechanism behind the observed changes in regulation.

    It is still controversial, whether moderately high haematocrit (Ht) and haemoglobin (Hb) values are risk factors for coronary heart disease. Using the computerized data-system of the Periodical Medical Examination (PME) of Phillips' International Electrical Company, a case-control study was carried out. Cases were male workers (n = 104, from 50 to 60 years of age) who had suffered a first, non-fatal myocardial infarction, and who had had a PME prior (on the average 16 months) to the occurrence of infarction. For each case two age-matched healthy controls were selected from the PME-attendancy list (= 208). For each subject information was abstracted from the PME-records about haematologic parameters and covariates (smoking, cholesterol, blood pressure, pulse-rate, weight, height, FEV5, consumption of antihypertensive agents). After dichotomizing the haematocrit and haemoglobin values at their whole sample means (0.46 l/l and 9.7 mmol/l respectively) in "low" (lower than or equal to the mean) and "high" (greater than the mean), crude odds-ratio's of 2.7 (95% CI: 1.6-4.6) and 2.1 (95% CI: 1.2-3.6) were found for Ht and Hb respectively, when comparing "high" with "low" levels. The associations between Ht and Hb, and the occurrence of myocardial infarction were still present after controlling for covariates using multiple logistic regression models, entering the continuous variables with their exact values. After adjustment, mean corpuscular volume (MCV) also appeared to be correlated with infarction. Our results confirm the hypothesis that moderately high haematocrit and--to a lesser extent--haemoglobin and MCV-values are risk factors for the occurrence of myocardial infarction.

    Full Text Available Aim and Objectives: To determine the value of routine pre-operative haematologic investigations in children undergoing orofacial cleft repair. Background: Although routine pre-operative laboratory screening tests are carried out traditionally, some studies suggest that they are not absolutely necessary in the management of elective surgical patients. Materials and Methods: This is a prospective cohort study carried out at a tertiary health facility located in Nigeria. A review of the laboratory investigations in 116 paediatric orofacial cleft patients undergoing surgery during a 6-year period was undertaken. Pre-operative laboratory investigations and peri-operative transfusion records were analysed for the frequency and impact of abnormal results on treatment plan and outcome using the Statistical Packages for the Social Scientists 16.0. Results: All the children had pre-operative packed cell volume (PCV check on admission for surgery. The PCV ranged from 23% to 43%, mean was 32.9 (±3.7%. Twenty-two children (18.6% had sub-optimal PCV (<30%. Patients with the lowest PCV values (23% and 26% were transfused pre-operatively. The lowest post-operative PCV was 23%, mean 30.8 (±3.3%. There was no occasion of post-operative blood transfusion. Eighty-six patients (72.9% had full or partial serum electrolyte and urea analysis. Screening for sickle-cell disease was rarely done. Fourteen intra- and post-operative complications were recorded. None of these were predictable by the results of pre-operative screening tests carried out. All the children were discharged home in satisfactory condition. Conclusions: Routine laboratory testing has minimal impact on management and outcome of orofacial cleft surgeries. However, haematocrit screening may be appropriate, particularly in clinically pale patients.

    We report the case of a 60-year-old man presenting bilateral progressive proptosis with diplopia, weight loss, tachycardia, nervosity, and stomach pain. These signs seemed at first to favor a diagnosis of Graves'ophthalmopathy. Thyroid tests were negative and the initial orbital CT scan was considered normal. A new radiological investigation 4 months later in our hospital revealed typical hypertrophy of the extraocular muscles compatible with orbital metastasis. The systemic investigations demonstrated a pulmonary tumor, multiple hepatic lesions, and several pigmented nodules of gastric mucosa. The pathology of pulmonary and gastric specimens confirmed the diagnosis of malignant melanoma. The primary lesion remains unknown. The authors discuss the differential diagnoses of orbital metastasis and the radiological characteristics of orbital metastasis in malignant melanoma.

    Constitutively activated oncogenic signaling via genetic mutations such as in the EGFR/PI3K/Akt and Ras/RAF/MEK pathways has been recognized as a major driver for tumorigenesis in most cancers. Recent insights into tumor metabolism have further revealed that oncogenic signaling pathways directly promote metabolic reprogramming to upregulate biosynthesis of lipids, carbohydrates, protein, DNA and RNA, leading to enhanced growth of human tumors. Therefore, targeting cell metabolism has become a novel direction for drug development in oncology. In malignant gliomas, metabolism pathways of glucose, glutamine and lipid are significantly reprogrammed. Moreover, molecular mechanisms causing these metabolic changes are just starting to be unraveled. In this review, we will summarize recent studies revealing critical gene alterations that lead to metabolic changes in malignant gliomas, and also discuss promising therapeutic strategies via targeting the key players in metabolic regulation.

    Endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are breast, renal and colorectal carcinomas. In this study, we aimed to evaluate the clinical, radiographic and bronchoscopic aspects of patients with EBM who were diagnosed between 1992 and 2002. Data about patients' clinical conditions, symptoms, radiographic and endoscopic findings, and histopathological examination results were investigated. EBM was defined as bronchoscopically visible lesions histopathologically identical to the primary tumor in patients with extrapulmonary malignancies. We found 15 cases with EBM. Primary tumors included breast (3), colorectal (3), and renal (2) carcinomas; Malignant Melanoma (2); synovial sarcoma (1), ampulla of Vater adenocarcinoma (1), pheochromocytoma (1), hypernephroma (1), and Hodgkin's Disease (1). The most common symptoms were dyspnea (80%), cough (66.6%) and hemoptysis (33.3%). Multiple (40%) or single (13.3%) pulmonary nodules, mediastinal or hilar lymphadenopathy (40%), and effusion (40%) were the most common radiographic findings. The mean interval from initial diagnosis to diagnosis of EBM was 32.8 months (range, 0-96 months) and median survival time was 18 months (range, 4-84). As a conclusion, various extrapulmonary tumors can metastasize to the bronchus. Symptoms and radiographic findings are similar with those in primary lung cancer. Therefore, EBM should be discriminated from primary lung cancer histopathologically. Although mean survival time is usually short, long-term survivors were reported. Consequently, treatment must be planned according to the histology of the primary tumor, evidence of metastasis to other sites and medical status of the patient.

    The very rare benign chondroblastoma occasionally invades soft tissues and may grow beyond the epiphysis into the metaphysis. In the present case such a tumour did not show the typical radiological appearances, but presented malignant features both on plain films and on the angiogram. The importance of biopsy of tumours which cannot be identified with certainty must be stressed before radical surgery is carried out.

    Malignant fibroous histiocytoma (MFH) is an aggressive soft tissue sarcoma, that most frequently occurs in the muscles of the extremities and in abdominal or in retroperitoneal space of young adults. It is seldom confined to the skin and subcutaneous tissue. It is rarely diagnosed before excision and pathological exam, and has an unfavorable prognostic in some cases. This work reports the case of a 94 years old patient with originally cutaneous MFH stressing the importance of the early diagnosis.

    Irvine, David A; Copland, Mhairi

    2012-03-08

    The Hedgehog pathway is a critical mediator of embryonic patterning and organ development, including hematopoiesis. It influences stem cell fate, differentiation, proliferation, and apoptosis in responsive tissues. In adult organisms, hedgehog pathway activity is required for aspects of tissue maintenance and regeneration; however, there is increasing awareness that abnormal hedgehog signaling is associated with malignancy. Hedgehog signaling is critical for early hematopoietic development, but there is controversy over its role in normal hematopoiesis in adult organisms where it may be dispensable. Conversely, hedgehog signaling appears to be an important survival and proliferation signal for a spectrum of hematologic malignancies. Furthermore, hedgehog signaling may be critical for the maintenance and expansion of leukemic stem cells and therefore provides a possible mechanism to selectively target these primitive cell subpopulations, which are resistant to conventional chemotherapy. Indeed, phase 1 clinical trials of hedgehog pathway inhibitors are currently underway to test this hypothesis in myeloid leukemias. This review covers: (1) the hedgehog pathway and its role in normal and malignant hematopoiesis, (2) the recent development of clinical grade small molecule inhibitors of the pathway, and (3) the potential utility of hedgehog pathway inhibition as a therapeutic strategy in hemato-oncology.

    Full Text Available ABSTRACT INTRODUCTION: Carcinomatous degeneration is a rare and late complication developing decades after the diagnosis of chronic osteomyelitis. OBJECTIVES: To present the results from a retrospective study of six cases of squamous cell carcinoma arising from chronic osteomyelitis. METHODS: Six cases of chronic osteomyelitis related to cutaneous squamous cell carcinoma were identified. The cause and characteristics of the osteomyelitis were analyzed, as well as time up to malignancy, the suspicion signs for malignancy, the localization and histological type of the cancer, and the type and result of the treatment. RESULTS: The mean time between osteomyelitis onset and the diagnosis of malignant degeneration was 49.17 years (range: 32-65. The carcinoma resulted from tibia osteomyelitis in five cases and from femur osteomyelitis in one. The pathological examination indicated cutaneous squamous cell carcinoma in all cases. All the patients were staged as N0M0, except for one, whose lomboaortic lymph nodes were affected. The treatment consisted of amputation proximal to the tumor in all patients. No patient presented signs of local recurrence and only one had carcinoma metastasis. CONCLUSION: Early diagnosis and proximal amputation are essential for prognosis and final results in carcinomatous degeneration secondary to chronic osteomyelitis.

    Feeding experiment was accomplished at the Aquaculture unit (Close system), Grdarasha station, Agriculture College, University of Salahaddin, Erbil, Kurdistan Region, to investigate different levels of Aquagrow E (AGEY) brewer's yeast cell Saccharomyces cerevisiae on the haematological and water quality of common carp fingerlings Cyprinus carpio. The basal diet was formulated to contain 34% protein and 10% lipid and the dietary treatments were supplemented with 0.5%, 1% and 1.5% of AGEY diet. A total of 180 Common carp (10.30 ± 0.27 g) fed on experimental diets for 10 weeks. Water quality assessment for well water and pond water for rearing Cyprinus carpio in cage system conducted weekly, while some parameters including pH, EC, water temperature and DO were monitored daily during the entire periods of study. Values of total hardness, alkalinity, ammonia and nitrate for studied water samples were within normal ranges for rearing Cyprinus carpio. Mean concentration of GPT, GOT and Glucose were 104 to 170 U/L, 1371 to 3308 U/L and 34 to 63mg/dl respectively, moreover, highest levels were observed in treatments with higher concentrations of yeast in its food except for blood sugar. Slight variation in lipase enzyme were found between control and treatment groups, while levels of amylase enzyme were increased toward cages with higher levels of yeast until T1 and then decreased toward T3. Total protein levels were increased to toward higher levels of yeast in food of Cyprinus carpio fish. Haematological results showed highest levels of WBC and platelets in treatments cages than control group. Levels of RBCs and hemoglobin were highest in treatment group 1 with 0.5%of yeast than treatments higher yeast concentrations. Significant correlation was found in haematological parameters between control and treatments.

In this study, we investigate how the presence of the sickle cell trait affects the haematological profile of AS persons with malaria, in comparison with similarly infected persons with HbAA. This study is based on the hypothesis that the sickle cell trait plays a protective role against malaria. Children from an endemic malaria transmission area in Yemen were enrolled in this study. Hematological parameters were estimated using manual methods, the percentage of parasite density on stained thin smear was calculated, haemoglobin genotypes were determined on paper electrophoresis, ferritin was measured using enzyme-linked immunosorbent assay, serum iron and TIBC were assayed using spectrophotometer, transferrin saturation index was calculated by dividing serum iron by TIBC and expressing the result as a percentage. Haematological parameters were compared in HbAA- and HbAS-infected children. Falciparum malaria parasitaemia was confirmed in the blood smears of 62 children, 44 (55.7%) of AA and 18 (37.5%) AS, so there was higher prevalence in HbAA children (P = 0.047). Parasite density was lower in HbAS- than HbAA-infected children (P = 0.003). Anaemia was prominent in malaria-infected children, with high proportions of moderate and severe forms in HbAA (P = 0.001). The mean levels of haemoglobin, packed cell volume, reticulocyte count, platelets count, lymphocytes, eosinophils, and serum iron were significantly lower while total leukocytes, immature granulocytes, monocytes, erythrocyte sedimentation rate, transferrin saturation, and serum ferritin were significantly higher in HbAA-infected children than HbAS-infected children. Infection with Plasmodium falciparum malaria caused more significant haematological alterations of HbAA children than HbAS. This study supports the observation that sickle cell trait

    To investigate the frequency and the spectrum of major opportunistic infections (OIs), evaluate the major clinical factors associated with each specific OI, and identify the risk factors for in-hospital death among HIV patients in East China.A retrospective cohort study was made including all the HIV-infected patients who were admitted for the first time to the Shanghai Public Health Clinical Center during June 1, 2013 to June 1, 2015. The demographic and clinical data were collected. Comparison of continuous variables was analyzed by one-way ANOVA and rank sum test. Person χ test and Fisher exact test were applied to analyze the categorical variables. A Cox proportional hazards regression model was used to determine the risk for the occurrence of in-hospital death.In total, 920 patients were enrolled with age of 41.59 ± 13.36 years and 91% male. Median CD4 was 34 (IQR, 13-94) cells/μL. Among these patients, 94.7% acquired OIs while the rest developed malignancies. Pneumocystis pneumonia and bacterial coinfection (42.1%) was found to be the most common OIs, followed by tuberculosis (31.4%), CMV (20.9%), Cryptococcosis (9.0%), and MAC infection (5.2%). Of the above 5 major OIs, CMV-infected patients had the lowest median CD4 cell count 22.50 (IQR, 7.50-82.00) while the patients with tuberculosis infection had the highest count 61.00 (IQR, 27.00-176.00). In-hospital death rate was 4.2 per 100 person-years among these patients. Of note, admitted patients with 2 types of OIs (2.20, 95% CI 1.39-3.48) and those patients who were 40-year old or older (1.75, 95% CI 1.10-2.78) had a higher risk of such death.Pneumocystis pneumonia and tuberculosis were still the leading causes for the admission of HIV-infected patients in East China, and these patients tended to have very low CD4 cell counts. It is believed that expanding the HIV screening test and pushing the infected ones get ART earlier is required for generating a more successful HIV management strategy.

    The evaluation of hormonal responses to stress in reptiles relies on acquisition of baseline corticosterone concentrations; however, the stress associated with the restraint needed to collect the blood samples can affect the results. The purpose of this study was to determine a time limit for the collection of blood samples to evaluate baseline corticosterone, haematological and biochemical results in nesting (n = 11) and rehabilitating (n = 16) loggerhead sea turtles (Caretta caretta). Blood samples were collected from the dorsal cervical sinus of each turtle immediately after touching the animal (t 0; 0-3 min) and 3 (t 3; 3-6 min), 6 (t 6; 6-9 min; nesting turtles only), 10 (t 10; 10-13 min) and 30 min (t 30; rehabilitating turtles only) after the initial hands-on time. Consistent between the rehabilitating and nesting turtles, there was a subtle yet significant increase in white blood cell counts over time. Despite the fact that white blood cell counts increased during the sampling period, there was no direct correlation between white blood cell count and corticosterone in the sampled turtles. In the nesting turtles, significant elevations in corticosterone were noted between t 0 and t 3 (P = 0.014) and between t 0 and t 6 (P = 0.022). Values at t 10 were not significantly different from those at t 0 (P = 0.102); however, there was a trend for the corticosterone values to continue to increase. These results suggest that sampling of nesting loggerhead sea turtles within 3 min of handling will provide baseline corticosterone concentrations in their natural environment. Significant elevations in corticosterone were also noted in the rehabilitating loggerhead sea turtles between t 0 and t 10 (P = 0.02) and between t 0 and t 30 of sampling (P = 0.0001). These results suggest that sampling of loggerhead sea turtles within 6 min of handling should provide baseline corticosterone concentrations in a rehabilitation setting. The

    Background Membranous nephropathy (MN) can be associated with malignancy. However, the relative risk for malignancy remains unclear. It has been reported that higher numbers of inflammatory cells seen in the glomeruli at biopsy correlate with the occurrence of malignancy in patients with MN and might be used to direct screening. Methods We examined the occurrence of malignancy in 201 MN patients in Auckland, New Zealand. We also examined the pathology of renal biopsies from 17 MN patients with malignancies and compared the number of inflammatory cells per glomerulus with matched control patients with MN but no malignancy. Results 40 malignancies were identified in 37 patients, 28 of which occurred after the MN diagnosis. The standardized incidence ratio (SIR) was 2.1 (95% CI, 1.3–2.85) which was similar between patients ≥ 60 years and those <60 years. The median number of inflammatory cells per glomerulus did not differ between MN patients with and without malignancy at 1.86 (IQR, 1.17–2.7) and 2.07 (IQR, 1.17–3.65), respectively (p value 0.56). Conclusions The relative risk of malignancy in MN patients was similar across different age groups. The number of inflammatory cells per glomerulus did not differentiate between MN patients with and without malignancies. PMID:28791182

    We present an incarcerated Morgagni hernia in an octogenarian with incidental right-sided colonic malignancy who was admitted to clinic due to abdominal pain and symptoms of intestinal obstruction. An 85-old male patient had a history of constipation, abdominal distension, pain, vomiting, nausea and radiographic features of bowel obstruction and mediastinal mass in right lower chest. Under suspicion of acute intestinal obstruction due to transverse colon herniation in thorax through Morgagni foramen, emergent laparotomy was performed. Morgagni foramen was located on the right-sided anterior diaphragm and Morgagni hernia which contained of incarcerated transverse colon, greater omentum and 70 cm small bowel after releasing the adhesions was gently reduced. In the same time right-sided colon malignancy was found. Morgagni foramen measuring 7 cm in diameter was sutured first and decompressive bypass ileocolic anastomosis was created. The role of emergent surgery, even in advanced age, is emphasized.

    A 62-year-old man with pain in his hip joints and back was admitted to our hospital. His chest radiograph and CT showed a huge mass extending from the left upper pericardium to the left hilum, but no pleural effusion or other lesions. A contrast-enhanced abdominal CT showed multiple metastases to bones and both kidneys. Bronchoscopy revealed obstruction of the left B3 by a visible tumor. The biopsy specimens of the initial immunohistochemical staining were slightly positive for calretinin. However, we diagnosed the condition as sarcomatoid carcinoma of the lung on the basis of the clinical evaluation. Although radiotherapy was administered, his condition rapidly deteriorated and he died due to progression of the disease. Autopsy revealed extensive invasion, suggesting mesothelioma. Therefore, immunohistochemical staining was performed; the findings revealed sarcomatoid malignant mesothelioma. In conclusion, we encountered a rare case of sarcomatoid malignant mesothelioma (stage IV).

    Full Text Available Abstract Background Malignant schwannoma of the upper mediastinum originating from the vagus nerve is extremely rare. Case presentation A 46-year-old female was admitted for a left cervical mass which was associated with both hoarseness and Horner's syndrome. Chest computed tomography showed a mass extending from the left upper mediastinum to the left supraclavicular area. A fine needle aspiration cytological examination suggested primary lung cancer stage IIIB large cell carcinoma. After administering induction chemo-radiotherapy, a complete surgical resection was performed. The tumor was found to involve both the left vagus nerve and the left sympathetic nerve. Histological examination of the resected specimen revealed the tumor to be malignant schwannoma. Conclusion Despite incorrect preoperative diagnosis, the multimodality treatment administered in this case, including induction chemo-radiotherapy and surgery, proved to be effective.

    Full Text Available Malignant mixed Mullerian tumors are composed of a mixture of sarcoma and carcinoma. The carcinomatous element is usually glandular, whereas the sarcomatous element may resemble normal endometrial stroma (homologous or so-called carcinosarcoma. Here, we present a homologous type of malignant mixed Mullerian tumor of the uterus that presented as a cervical mass. We describe a 55-year-old patient who had a cervical mass arising from the uterus. We performed total abdominal hysterectomy and bilateral salpingo-oophorectomy and surgical staging (including (peritoneal washings, suspicious areas or peritoneal surfaces sampled, infracolic omental sampling, pelvic and paraaortic lymph node sampling, and appendectomy. Carcinosarcomas of the uterine cervix are extremely rare, and when a post-menopausal woman with a cervical mass is admitted to the gynecology clinic, the physician should keep in mind that the mass might be a carcinosarcoma.

    Forty-five life insurance companies responded to a questionnaire on insurance industry attitudes towards patients with a history of malignancy other than skin carcinoma. Although the criteria for acceptance, provisions of the policy, and philosophy about adjuvant treatment varied, all companies would underwrite such patients provided that at application there was no evidence of persistent or recurrent disease or severe complications of therapy. The concept of excess mortality (observed death rates versus standard expected death rates) is used with other factors in calculating premiums. Legal and ethical responsibilities of physicians associated with insurance applications are briefly discussed.

    Clinical practice in haematological oncology often involves difficult diagnostic and treatment decisions. In this context, understanding patients' information needs and the functions that information serves for them is particularly important. We systematically reviewed qualitative and quantitative evidence on haematological oncology patients' information needs to inform how these needs can best be addressed in clinical practice. PsycINFO, Medline and CINAHL Plus electronic databases were searched for relevant empirical papers published from January 2003 to July 2016. Synthesis of the findings drew on meta-ethnography and meta-study. Most quantitative studies used a survey design and indicated that patients are largely content with the information they receive from physicians, however much or little they actually receive, although a minority of patients are not content with information. Qualitative studies suggest that a sense of being in a caring relationship with a physician allows patients to feel content with the information they have been given, whereas patients who lack such a relationship want more information. The qualitative evidence can help explain the lack of association between the amount of information received and contentment with it in the quantitative research. Trusting relationships are integral to helping patients feel that their information needs have been met. © 2017 John Wiley & Sons Ltd.

    Invasive fungal infection (IFI) caused by filamentous fungi remains a very severe infectious complication in patients with onco-haematological diseases. Last advances in the diagnostic and therapeutic fields, today we know that their contributions are limited. Something similar can be said of clinical trials especially in relation to some changes in the characteristics of the host. The development of promising diagnostic techniques and the relative expansion in the number of antifungal agents has been associated with diversification of therapeutic strategies (prophylaxis with extended-spectrum azoles and preemptive antifungal treatment). However, the low sensitivity of AGA testing in some circumstances, and the potential delay in starting treatment due to logistic reasons, has been reflected by a greater mortality in certain type of patients and a significant increase in the days of treatment. All these circumstances has once again focus attention to the empirical approach as a central strategy in high-risk patients. The objective of this article is to review the clinical experience in the treatment of IFI in onco-haematological patients according to data published in the literature in the last decade and to present a set of recommendations.

    Two mid-range haematology analysers (Abbott CELL-DYN Ruby and Sysmex XT-2000i) were evaluated to determine their analytical performance and workflow efficiency in the haematology laboratory. In total 418 samples were processed for determining equivalence of complete blood count (CBC) measurements, and 100 for reticulocyte comparison. Blood smears served for assessing the agreement of the differential counts. Inter-instrument agreement for most parameters was good although small numbers of discrepancies were observed. Systematic biases were found for mean cell volume, reticulocytes, platelets and mean platelet volume. CELL-DYN Ruby WBC differentials were obtained with all samples while the XT-2000i suppressed differentials partially or completely in 13 samples (3.1%). WBC subpopulation counts were otherwise in good agreement with no major outliers. Following first-pass CBC/differential analysis, 88 (21%) of XT-2000i samples required further analyser processing compared to 18 (4.3%) for the CELL-DYN Ruby. Smear referrals for suspected WBC/nucleated red blood cells and platelet abnormalities were indicated for 106 (25.4%) and 95 (22.7%) of the XT-2000i and CELL-DYN Ruby samples respectively. Flagging efficiencies for both analysers were found to be similar. The Sysmex XT-2000i and Abbott CELL-DYN Ruby analysers have broadly comparable analytical performance, but the CELL-DYN Ruby showed superior first-pass efficiency. © 2010 Blackwell Publishing Ltd.

    The effects of vaccination on avian blood parameters are poorly understood. The present study was designed to evaluate whether different strains (Ulster 2C, B1, live LaSota and inactivated LaSota) of Newcastle disease vaccines had an effect on the haematological profile of female turkeys. Seventy-five female turkeys were allocated to treatment groups according to vaccination strain. All the birds, except those in the control group, were vaccinated at 32 weeks of age and revaccinated at 40 and 48 weeks of age. Blood samples were obtained for haematological analyses and serum samples for the haemagglutination inhibition test. Haemoglobin concentration was significantly lower (p < 0.05) in vaccinated female turkeys than in the control birds 28 days after vaccination. Monocytes were significantly higher (p < 0.05) in 44-week-old female turkeys vaccinated with inactivated LaSota strain compared with the other groups. Turkeys vaccinated with the B1 strain showed significantly higher (p < 0.05) total white blood cell counts compared with the other groups vaccinated with various commercial strains of the Newcastle disease virus. In conclusion, female turkeys showed significant differences in haemoglobin concentrations, monocytes and white blood cell counts when vaccinated against Newcastle disease.

The aim of the current study was to determine selected haematological changes that occur in Clarias gariepinus (Burchell, 1822. infected with trypanosomes. Blood films were prepared according to standard techniques to confirm trypanosome infections and whole blood was collected, the serum and plasma separated, and prepared for albumin and total protein concentration analysis. Plasma albumin levels were significantly higher in infected wild caught fish than in uninfected wild caught fish and uninfected breeding stock. Serum albumin levels were significantly lower in infected wild caught fish when compared to uninfected breeding stock. The total plasma and serum protein levels were within the normal range for C. gariepinus, that is, 3 g – 6 g/100 mL. The total plasma protein levels varied significantly between the three groups. However, the total serum protein levels were only significantly different between uninfected breeding stock and uninfected wild caught fish, as well as uninfected breeding stock and infected wild caught fish. The total protein levels were significantly higher in infected wild caught fish than in the other groups, a possible indication of an infection or inflammatory host response.

    Biochemical and haematological reference intervals (RIs) have been reported for sea turtles, but their value for ante-mortem disease diagnosis may be limited due to small sample sizes and outdated statistical analyses. In the present study, 290 green sea turtles (Chelonia mydas) were captured, clinically assessed and blood sampled. Of these, 211 were classified as 'clinically healthy' and 25 as 'clinically unhealthy'. RIs were estimated using data from the healthy turtles and compared with blood values from the unhealthy animals. All of the unhealthy animals had plasma biochemical and haematological values outside one or more RIs (albumin, 48% of unhealthy animals; alkaline phosphatase, 35%; aspartate transaminase, 13%; creatinine, 30%; globulin, 3%; glucose, 34%; lactic dehydrogenase, 26%; phosphorus, 22%; sodium, 13%; thrombocytes, 57%; and monocytes, 5%). Among small immature turtles, those with Chelonibia testudinaria plastron barnacle counts 20 were three times more likely to be unhealthy than those with no barnacles. In addition, small immature and mature turtles were more likely to be unhealthy than large immature turtles.

    Haematological profile-haemoglobin concentration (Hb), total erythrocytes count (TEC), packed cell volume (PCV), erythrocyte indices-mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were studied in crossbred dairy cattle (Holstein Friesian x Sahiwal) under various physiological states: non-pregnant heifers (NPH), pregnant heifers (PH), empty dry cows (EDC), pregnant lactating cows (PLC), medium yield early lactating cows (MYELC) and high yield early lactating cows (HYELC) during summer and winter seasons at 1700 metres altitude from mean sea level in the Central Himalayas. On comparison of annual means, the highest values of Hb and PCV were recorded in PH and of TEC in NPH, whereas the lowest values of these parameters were found in EDC. The Hb and TEC tended to decrease with increasing milk yield. Comparison of annual means of erythrocyte indices revealed the highest MCV and MCH in EDC, which simultaneously showed the lowest MCHC. Significant seasonal variations in haematological profile were recorded. The overall group mean (OGM) of Hb, MCV, MCH and MCHC was found to be significantly higher (P OGM (P < 0.01) during the winter season.

    Full Text Available Turkeys are of considerable economic and social significance to the traditional life of Nigerians but its production has been hampered by high cost of feedstuff. This study was carried out to determine the haematological parameters and serum chemistry of local grower turkeys fed Samsorg 17 and ICSV 400 sorghum varieties as replacement for higher cost maize in their diet. One hundred six weeks old grower turkeys were divided into nine groups of three replicates each on sex and weight equalization basis. The groups were randomly assigned to nine experimental turkey grower diets containing 0, 25, 50, 75 and 100% replacement level of maize with each of samsorg17 and ICSV400 varieties of sorghum. The feeding trial lasted 42 days. Six turkeys were randomly selected on trial day 38, blood samples were collected for haematological and serum biochemical analysis. RBC, HB, WBC and PCV were determined while MCHC, MCH AND MCV were calculated using appropriate formulae. Serum protein (albumin and globulin, sugar, cholesterol, urea, minerals and enzymes were also determined. The result indicated that only WBC count was higher and the serum sugar and creatinine was lower than normal range. The ALP level declined while SGPT increased with increasing dietary sorghum but SGOT followed no pattern. There was no observed adverse effect on the blood parameters of experimental grower turkeys fed these sorghum varieties and is therefore recommended as replacement for maize in their diets.

    We investigated the iron-related haematological parameters in both male and female athletes participating in different sporting disciplines necessitating different metabolic energy demands. A total of 873 athletes (514 males, mean age: 22.08 ± 4.95 years and 359 females, mean age: 21.38 ± 3.88 years) were divided according to gender and to the predominant energy system required for participation in sport (aerobic, anaerobic or mixed) and haematological and iron-related parameters were measured. For both male and female athletes, significant differences related to the predominant energy system were found at a general level: male (Wilks' λ = 0.798, F = 3.047, p iron and sTfR significantly differed in all three groups of male and female athletes (p athletes was significantly higher only in those who required an anaerobic energy source (p athletes. According to the ferritin cutoff value of 22 μg/L, in females, whole body iron, sTfR and hypochromic erythrocytes were significantly higher in all three groups of athletes than those below the aforementioned cutoff value (p iron proved to be reliable parameters for monitoring the dynamics of iron metabolism and could contribute to successful iron-deficiency prevention.

  17. From Benign to Malign in a Case of Cervical Adenopathy in a 17-Year-Old Adolescent: Diagnostic Traps

    Full Text Available Distinguishing between benign and malign adenopathies remains a challenge and could represent a source of error in a diagnosis. We report a case of right laterocervical adenopathy in a 17-year-old teenager admitted to hospital with an episode of fever associated with dysphagia, congested pharynx, and pultaceous deposits. Initially the adenopathy was considered to be secondary to a coinfection with Streptococcus B-hemolytic and Epstein-Barr virus, as suggested by the positive bacteriological and serological tests. The onset of the adenopathy before the episode and the ultrasound modifications raised the suspicion of a malignancy, later confirmed by the histopathologic examination of the lymph node excision. The final diagnosis was nodal metastasis of an undifferentiated lymphoepithelial carcinoma with an ENT starting point. Currently, the adolescent is hospitalised in the ENT ward, where the pharynx carcinoma with nodal metastasis was confirmed. Sometimes the infectious context can mask or unmask a malign chronic disease with insidious evolution.

    The purpose of the study is to compare demographics, intensive care unit (ICU) admission characteristics, and ICU outcomes among adults with childhood-onset chronic conditions (COCCs) admitted to US pediatric and adult ICUs. Retrospective cross-sectional analyses of 6088 adults aged 19 to 40 years admitted in 2008 to 70 pediatric ICUs that participated in the Virtual Pediatric Intensive Care Unit Performance Systems and 50 adult ICUs that participated in Project IMPACT. Childhood-onset chronic conditions were present in 53% of young adults admitted to pediatric units, compared with 9% of those in adult units. The most common COCC in both groups were congenital cardiac abnormalities, cerebral palsy, and chromosomal abnormalities. Adults with COCC admitted to pediatric units were significantly more likely to be younger, have lower functional status, and be nontrauma patients than those in adult units. The median ICU length of stay was 2 days, and the intensive care unit mortality rate was 5% for all COCC patients with no statistical difference between pediatric or adult units. There are marked differences in characteristics between young adults with COCC admitted to pediatric ICUs and adult ICUs. Barriers to accommodating these young adults may be reasons why many such adults have not transitioned from pediatric to adult critical care. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Full three-dimensional unsteady numerical investigation on an axial air turbine in 50% partial admission is conducted. The partial admission turbines are under different unsteady loading and unloading process, as well as flow parameters, respectively. The loss coefficient and static pressure distributions at the key position are presented in detail to analyze the nonuniformity originated from partial admission. The results show that the nonuniformity decreases along flow direction and the efficiency of control stage also decreases but with the uniformity improved downstream of the rotors with increasing admitting numbers in equal partial admission degree. The reasons for efficiency decreasing are reasonably explained with windage and sector end losses presented by static entropy distributions. The periodic changes of unsteady forces in amplitude and direction are also compared and transformed in the frequency domain by FFT method. The largest circumferential exciting force factor which is remarkably larger than the corresponding axial exciting force factor decreases by 13.2% with the increase of admitting arc number. Compared with the common distribution of two symmetric admitting arcs, the maximum exciting force factor of triangle admitting arc distribution drops 11.3% with the mere efficiency decrease of 1.32%. The multiple admitting arc turbines are more conducive to be applied to submarines which concerns more about exciting force other than efficiency. Efficiency and unsteady forces are both worth being taken into consideration in the practical applications.

    Full Text Available Hematological malignancies such as leukemias, lymphomas, multiple myeloma (MM, and the myelodysplastic syndromes (MDSs primarily affect adults and are difficult to treat. For high-risk disease, hematopoietic stem cell transplant (HCT can be used. However, in the setting of autologous HCT, relapse due to contamination of the autograft with cancer cells remains a major challenge. Ex vivo manipulations of the autograft to purge cancer cells using chemotherapies and toxins have been attempted. Because these past strategies lack specificity for malignant cells and often impair the normal hematopoietic stem and progenitor cells, prior efforts to ex vivo purge autografts have resulted in prolonged cytopenias and graft failure. The ideal ex vivo purging agent would selectively target the contaminating cancer cells while spare normal stem and progenitor cells and would be applied quickly without toxicities to the recipient. One agent which meets these criteria is oncolytic viruses. This paper details experimental progress with reovirus, myxoma virus, measles virus, vesicular stomatitis virus, coxsackievirus, and vaccinia virus as well as requirements for translation of these results to the clinic.
