    Full Text Available Splenectomy, while often necessary in otherwise healthy patients after major trauma, find its primary indication for patients with an underlying malignant or nonmalignant hematologic diseases. Indications of splenectomy for hematologic diseases have been reducing in the last few years, due to improved diagnostic and therapeutic tools. In high-income countries, there is a clear decrease over calendar time in the incidence of all indication splenectomy except nonmalignant hematologic diseases. However, splenectomy, even if with different modalities including laparoscopic splenectomy and partial splenectomy, continue to be a current surgical practice both in nonmalignant hematologic diseases, such as Immune Thrombocytopenic Purpura (ITP, Autoimmune Hemolytic Anemia (AIHA, Congenital Hemolytic Anemia such as Spherocytosis, Sickle Cell Anemia and Thalassemia and Malignant Hematological Disease, such as lymphoma. Today millions of people in the world are splenectomized. Splenectomy, independently of its cause, induces an early and late increase in the incidence of venous thromboembolism and infections. Infections remain the most dangerous complication of splenectomy. After splenectomy, the levels of antibody are preserved but there is a loss of memory B cells against pneumococcus and tetanus, and the loss of marginal zone monocytes deputed to immunological defense from capsulated bacteria. Commonly, the infections strictly correlated to the absence of the spleen or a decreased or absent splenic function are due to encapsulated bacteria that are the most virulent pathogens in this set of patients. Vaccination with polysaccharide and conjugate vaccines again Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis should be performed before the splenectomy. This practice reduces but does not eliminate the occurrence of overwhelming infections due to capsulated bacteria. At present, most of infection found in splenectomized patients

    Formalin-fixed, paraffin-embedded lungs exhibiting a variety of nonmalignant disorders were studied by immunoperoxidase staining using antibodies specific for surfactant apoprotein, IgG, IgM, IgA, albumin, fibrinogen, and lysozyme. Normal Type II pneumocytes showed staining for surfactant apoprotein in the perinuclear region only. The extent and intensity of staining for apoprotein was markedly increased in reactive Type II pneumocytes. This increase appeared to be a nonspecific reaction to lung injury. The intra-alveolar material in pulmonary alveolar proteinosis stained intensely for surfactant apoprotein, indicating that the accumulated proteinaceous material contained pulmonary surfactant. Type II pneumocytes in pulmonary alveolar proteinosis exhibited hyperplasia as well as hypertrophy. The few macrophages in lung affected by pulmonary alveolar proteinosis stained intensely for lysozyme. The excessive intraalveolar accumulation of proteinaceous material in pulmonary alveolar proteinosis may be the result of both an over-production as well as a deficient removal of pulmonary surfactant.

    Pulmonary hypertension (PH), a serious disorder with a high morbidity and mortality rate, is known to occur in a number of unrelated systemic diseases. Several hematological disorders such as sickle cell disease, thalassemia and myeloproliferative diseases develop PH which worsens the prognosis. Associated oxidant injury and vascular inflammation cause endothelial damage and dysfunction. Pulmonary vascular endothelial damage/dysfunction is an early event in PH resulting in the loss of vascular reactivity, activation of proliferative and antiapoptotic pathways leading to vascular remodeling, elevated pulmonary artery pressure, right ventricular hypertrophy and premature death. Hemolysis observed in hematological disorders leads to free hemoglobin which rapidly scavenges nitric oxide (NO), limiting its bioavailability, and leading to endothelial dysfunction. In addition, hemolysis releases arginase into the circulation which converts L-arginine to ornithine, thus bypassing NO production. Furthermore, treatments for hematological disorders such as immunosuppressive therapy, splenectomy, bone marrow transplantation, and radiation have been shown to contribute to the development of PH. Recent studies have shown deregulated iron homeostasis in patients with cardiopulmonary diseases including pulmonary arterial hypertension (PAH). Several studies have reported low iron levels in patients with idiopathic PAH, and iron deficiency is an important risk factor. This article reviews PH associated with hematological disorders and its mechanism; and iron homeostasis and its relevance to PH. PMID:28070238

    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

    2015-01-01

    Synopsis A finding of eosinophilia in the peripheral blood can be the manifestation of a large number of different medical conditions, including benign or malignant disorders. From a diagnostic standpoint eosinophilia can be divided into reactive (secondary) or clonal (primary). There are three main types of WHO-defined eosinophilia-associated myeloid neoplasms (MN-eos): 1) myeloid and lymphoid neoplasms associated with rearrangements of PDGFRA, PDGFRB or FGFR1; 2) chronic eosinophilic leukemia, not otherwise specified (CEL-NOS); and 3) idiopathic hypereosinophilic syndrome (HES). Imatinib mesylate, a PDGFRA and PDGFRB inhibitor, has revolutionized the treatment of molecularly defined MN-eos. Second generation molecules are available for patients who fail imatinib. Novel agents, such as the anti-IL5 antibody mepolizumab, have been successfully used for the treatment of HES. The discovery of new, recurrent molecular alterations in patients with MN-eos may improve the diagnosis and therapy of this group of patients. This review focuses on the hematologist’s approach to a patient with eosinophilia as well as treatment options for patients with eosinophilic myeloid neoplasms. PMID:26209894

    Human T-lymphotropic virus type 1 (HTLV-1) was the first retrovirus identified in human. The current evidence is quite scarce regarding the potential role of HTLV-1 in pathogenesis of hematologic disorders and non-hematologic malignancies. The aim of this study is to evaluate the prevalence of HTLV-1 infection in patients with hematologic disorders and non-hematologic malignancies. This cross-sectional study was conducted on 505 cases of definite diagnosis of hematologic disorders including malignancies as well as non-malignant disorders such as polycythemia and myelofibrosis and non-hematologic malignancies referred to the hematology and medical oncology ward at Army Hospital 501 from January 2015 to January 2016. A 3-mL blood specimen was collected from each patient and tested for the presence of anti-HTLV-1 antibodies using enzyme-linked immunosorbent assay (ELISA). Data were analyzed using SPSS software package version 19 (IBM, New York, USA). Data are presented as mean ± SD if normally distributed and otherwise as median (range). Totally, 242 (48%) males and 263 (52%) females with a mean ± SD age of 52.09 ± 16.24 were enrolled in this study. In total, there were 9 (1.78%) cases positive for HTLV-1 infection including 4 males and 5 females. Seven out of 287 (2.4%) patients with hematologic disorders were infected by HTLV-1. In non-hematologic malignancies, 2 out of 211 cases were positive (0.9%). There was no HTLV-1 positive case in 7 patients with both hematologic and non-hematologic disorders. The difference in HTLV-1 infection prevalence between patients with hematologic disorders and non-hematologic malignancies was not statistically significant different (P = 0.31). There was no association between sex and transfusion history with HTLV-1 infection in this population (P = 0.9 and 0.7, respectively). Our study revealed that the prevalence of HTLV-1 in hematologic disorders is higher than the general population. Further larger prospective studies are

    At onset mitochondrial disorders (MID) frequently manifest as a mono-organic problem but turn into multisystem disease during the disease course in most of the cases. Organs/tissues most frequently affected in MID are the cerebrum, peripheral nerves, and the skeletal muscle. Additionally, most of the inner organs may be affected alone or in combination. Hematological manifestations of MID include aplastic, megaloblastic, or sideroblastic anemia, leukopenia, neutropenia, thrombocytopenia, or pancytopenia. In single cases either permanent or recurrent eosinophilia has been observed. Hematological abnormalities may occur together with syndromic or nonsyndromic MIDs. Syndromic MIDs, in which hematological manifestations predominate, are the Pearson syndrome (pancytopenia), Kearns-Sayre syndrome (anemia), Barth syndrome (neutropenia), and the autosomal recessive mitochondrial myopathy, lactic acidosis and sideroblastic anemia syndrome. In single cases with Leigh's syndrome, MERRF (myoclonic epilepsy and ragged-red fiber) syndrome, Leber's hereditary optic neuropathy, and Friedreich's ataxia anemia has been described. Anemia, leukopenia, thrombocytopenia, eosinophilia, or pancytopenia can frequently also be found in nonsyndromic MIDs with or without involvement of other tissues. Therapy of blood cell involvement in MID comprises application of antioxidants, vitamins, iron, bone marrow-stimulating factors, or substitution of cells.

    Full Text Available The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases, with particular reference to anemias and disorders of hemostasis. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases, with emphasis on anemia. Mesh phrases used in the search were: oral diseases AND anaemia; orofacial diseases AND anaemia; orofacial lesions AND anaemia; orofacial manifestations AND disorders of haemostasis. The Boolean operator "AND" was used to combine and narrow the searches. Anemic disorders associated with orofacial signs and symptoms include iron deficiency anemia, Plummer-Vinson syndrome, megaloblastic anemia, sickle cell anemia, thalassaemia and aplastic anemia. The manifestations include conjunctiva and facial pallor, atrophic glossitis, angular stomatitis, dysphagia, magenta tongue, midfacial overgrowth, osteoclerosis, osteomyelitis and paraesthesia/anesthesia of the mental nerve. Orofacial petechiae, conjunctivae hemorrhage, nose-bleeding, spontaneous and post-traumatic gingival hemorrhage and prolonged post-extraction bleeding are common orofacial manifestations of inherited hemostatic disorders such as von Willebrand′s disease and hemophilia. A wide array of anemic and hemostatic disorders encountered in internal medicine has manifestations in the oral cavity and the facial region. Most of these manifestations are non-specific, but should alert the hematologist and the dental surgeon to the possibilities of a concurrent disease of hemopoiesis or hemostasis or a latent one that may subsequently manifest itself.

    Full Text Available Parvovirus-B19 (PV-B19 is a member of Parvoviridae, which is one of the smallest DNA viruses. PV-B19-associated diseases usually serve as a good representation of the balance of virus, host response and the immune system. The diseases manifested with PV-B19 are erythema infectiosum, which is common in children, hydrops fetalis, transient pure red cell aplasia in patients with chronic hemolytic anemia, arthralgia - mostly observed in women, and chronic pure red cell aplasia in immunocompromised individuals. Cytopenia (bicytopenia, monocytopenia or pancytopenia may also accompany the diseases mentioned above. On the other hand, there are many diseases, including neurologic, vasculitic, hepatic, rheumatoid, nephritic, autoimmune, myocardial, and others in which the mechanisms of the diseases are not clear, which may be associated with PV-B19. The virus may manifest with unexpected and unexplained clinical pictures and lead to misdiagnosis. Therefore, hematologic disorders in any unestablished clinical diagnosis should be investigated for PV-B19 infection. However, serologic examination for PV-B19 diagnosis is not sufficient in immunocompromised status. The virus can be determined with polymerase chain reaction (PCR in the serum or tissue samples. Supportive therapy, blood transfusion and immunoglobulin are the conventional therapeutic interventions for PV-B19 today. Vaccination studies are under examination.

    Erythrocytes undergo ineffective erythropoesis, hemolysis, and premature eryptosis in sickle cell disease and thalassemia. Abnormal hemoglobin variants associated with hemoglobinopathy lead to vesiculation, membrane instability, and loss of membrane asymmetry with exposal of phosphatidylserine. This potentiates thrombin generation resulting in activation of the coagulation cascade responsible for subclinical phenotypes. Platelet activation also results in the release of microparticles, which express and transfer functional receptors from platelet membrane, playing key roles in vascular reactivity and activation of intracellular signaling pathways. Over the last decade, proteomics had proven to be an important field of research in studies of blood and blood diseases. Blood cells and its fluidic components have been proven to be easy systems for studying differential expressions of proteins in hematological diseases encompassing hemoglobinopathies, different types of anemias, myeloproliferative disorders, and coagulopathies. Proteomic studies of erythrocytes and platelets reported from several groups have highlighted various factors that intersect the signaling networks in these anucleate systems. In this review, we have elaborated on the current scenario of anucleate blood cell proteomes in normal and diseased individuals and the cross-talk between the two major constituent cell types of circulating blood.

    Full Text Available Published data on Japanese leukemia patients with a preleukemic hematological disorder were assessed. The reexamined cases were from the "Japona Centra Revuo Medicina" reported during the period from 1952 to 1971. Among preleukemic hematological disorders, hypoplastic anemia was the most frequently reported (41 of 62 cases. These "hypoplastic preleukemia" patients were rather elderly and terminated mostly in atypical myelocytic leukemia. The chief hematological feature of the hypoplastic preleukemia cases was the coexistence of a relative erythroid hyperplasia and a slight increase of myeloblasts in the bone marrow that was unusual in hypoplastic anemia. The presence of pancytopenia and hypocellular marrow with a relative erythroid hyperplasia combined with a slight increase of myeloblasts probably indicates hypoplastic preleukemia that terminates later in acute leukemia.

    Radiation therapy (RT) is an established and effective treatment modality in the management of a large variety of hyperproliferative disorders and benign neoplasms. Objective of this article is to summarize the updated DEGRO consensus S2e guideline recommendations. This report comprises an overview of the relevant aspects of the updated guidelines with regard to treatment decision, dose prescription, and RT technique for a selected group of disorders including Morbus Dupuytren (MD)/Morbus Ledderhose (ML), keloids, Peyronie's disease (induratio penis plastica, IPP), desmoid tumors, pigmented villonodular synovitis (PVNS), symptomatic vertebral hemangiomas (sVH), and Gorham-Stout syndrome (GSS). On the basis of results in the literature, we attempted to classify the level of evidence (LoE) and the grade of recommendation (GR) according to the Oxford criteria. There is comprehensive evidence in the literature that RT is a reasonable and effective treatment modality for the treatment of all the above-mentioned disorders. The LoE varies from 2c to 4, and GR varies from A to C. The use of RT can be recommended for the interdisciplinary management of most of the reported disorders. It can be used in the primary treatment approach and as an effective adjunct to other treatment modalities or in some indications as a valuable alternative treatment option. We hope that the updated DEGRO S2e consensus guideline recommendations are a helpful tool for radiation oncologists in the clinical decision-making process. (orig.)

    To summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign symptomatic functional disorders with low-dose radiotherapy. This overview reports on the role of low-dose radiotherapy in the treatment of functional disorders in cases of heterotopic ossification (HO) and Graves orbitopathy (GO). The most relevant aspects of the DEGRO S2e Consensus Guideline ''Radiation Therapy of Benign Diseases 2014'' regarding diagnostics, treatment decision, dose prescription, as well as performance of radiotherapy and results are summarized. For both indications (HO, GO), retrospective and some prospective analyses have shown remarkable effects in terms of symptom relief. Nevertheless, the level of evidence (LoE) and the grade of recommendation (GR) vary: LoE 1-2 and GR A-B (HO), LoE 2 and GR B (GO). Low-dose radiotherapy for benign symptomatic functional disorders has proven to be effective, according to different authors, for 25-100 % of the patients studied and therefore it may be a reasonable prophylactic and therapeutic option if noninvasive or invasive methods have been used without persistent success. For HO, a single-fraction dose of 7-8 Gy or fractionated radiation with five fractions of 3.5 Gy is recommended. For GO, single-fraction doses of 0.3-2.0 Gy, and total doses of 2.4-20 Gy/series, applied in one daily fraction are recommended. (orig.)

    The purpose of this article is to summarize the updated DEGRO consensus S2e guideline recommendations for the treatment of benign painful degenerative skeletal disorders with low-dose radiotherapy. This overview reports on the role of low-dose radiotherapy in the treatment of enthesiopathies (shoulder syndrome, trochanteric bursitis, plantar fasciitis, and elbow syndrome) and painful arthrosis (knee, hip, hand, and finger joints). The most relevant aspects of the DEGRO S2e Consensus Guideline Radiation Therapy of Benign Diseases 2014 regarding diagnostics, treatment decision, dose prescription as well as performance of radiotherapy and results are summarized. For all indications mentioned above, retrospective and some prospective analyses have shown remarkable effects in terms of pain relief. Nevertheless, the Level of Evidence (LoE) and the Grade of Recommendation (GR) vary: LoE 1b-4 and GR A-C. Low-dose radiotherapy for painful degenerative skeletal disorders is effective in the majority of the patients and therefore it may be a reasonable therapeutic alternative when simple and non-invasive methods have been used without persistent success. For all discussed entities, single fraction doses of 0.5-1.0 Gy and total doses of 3.0-6.0 Gy/series applied with 2-3 fractions per week are recommended. (orig.)

    Full Text Available Abstract Ribosomes are essential components of the protein translation machinery and are composed of more than 80 unique large and small ribosomal proteins. Recent studies show that in addition to their roles in protein translation, ribosomal proteins are also involved in extra-ribosomal functions of DNA repair, apoptosis and cellular homeostasis. Consequently, alterations in the synthesis or functioning of ribosomal proteins can lead to various hematologic disorders. These include congenital anemias such as Diamond Blackfan anemia and Shwachman Diamond syndrome; both of which are associated with mutations in various ribosomal genes. Acquired uniallelic deletion of RPS14 gene has also been shown to lead to the 5q syndrome, a distinct subset of MDS associated with macrocytic anemia. Recent evidence shows that specific ribosomal proteins are overexpressed in liver, colon, prostate and other tumors. Ribosomal protein overexpression can promote tumorigenesis by interactions with the p53 tumor suppressor pathway and also by direct effects on various oncogenes. These data point to a broad role of ribosome protein alterations in hematologic and oncologic diseases.

    Full Text Available Objective: Fungal infection is a significant problem, causing of infective deaths of leukemic patients. The situation in developing countries is not well documented. The purpose of this study was characterizing IFD by analyzing data retrospectively to determine the incidence, predisposing factors, diagnostic methods, efficacy of treatment, and the outcome in pediatric patients with hematological disorders. Materials and Methods: There were 160 children with leukemia (22 AML, 129 ALL and 9 with aplastic anemia (AA. The diagnostic criteria for IFD were defined according to the EORTC/MSG, 2008. IFD was classified as proven or probable. Empiric antifungal treatment with L-AmB was commenced by day 5-7 of persistent fever. Patients with invasive aspergillosis (IA who were refractory to primary treatment were commenced on voriconazole (VCZ. Salvage therapy as combination of VCZ and caspofungin was given to those with progressive infection. Results: The incidence of IFD was found 23 (14.3%. 19 with leukemia (14 ALL, 5 AML and 4 with aplastic anemia were diagnosed as IFD. IA was the dominant cause of infection (n=17 and the rest (n: 6 had candidiasis. Ten children had “proven” infection and 13 children were defined as “probable”. The most frequent site of infection was lungs. In our series, the most frequently used diagnostic methods were clinical findings (100% and radiologic methods (84%. The success rate of treatment for candidiasis and IA were found 60%, 71% respectively. IFD related death rate was found 30%.Conclusion: IFD is still a major morbidity and mortality reason in children with hematologic disorders. However, the availability of new antifungal treatments and diagnostic tests will improve the survival rates in these children.

    Full Text Available Objective: Posterior reversible leukoencephalopathy syndrome (PRES is characterized by headache, altered mental status, cortical blindness, and seizures associated with neuroradiological findings. It involves predominantly white matter of the parieto-occipital lobes. Several medications and disorders play a role in the etiology of PRES. In this study, we aimed to show how the prognosis of PRES in hematological diseases of childhood might be according to the etiological factors.Materials and Methods: Here, we report PRES in six patients, aged 4 to 14 years, with diagnoses of leukemia and aplastic anemia. Results: Suggested causes in our patients were chemotherapeutics, hypertension, infection and antimicrobial drug administration, tumor lysis syndrome, acute renal failure and hemodialysis, immunosuppressive drug administration, and hypomagnesemia. One of the patients died of sepsis, renal failure and pulmonary hemorrhage and another died of relapse after total recovery from PRES. The other four patients are under follow-up without problems. Conclusion: We suggest that PRES can recover fully with early diagnosis and treatment whereas it can show poor prognosis depending on the etiology.

    Studies of the association between seronegative or occult (OCI) hepatitis C virus (HCV) infection, and hematological disorders have yielded controversial results. The aim of this study was to investigate seronegative and OCI HCV infections in among patients with different hematological disorders. This study included 90 anti-HCV-negative patients with either benign or malignant hematological disorders (group I), along with 20 age- and sex-matched apparently healthy subjects, who served as controls (group II). We tested for HCV RNA in sera and PBMCs by RT-nested PCR and for liver enzyme activity. Seronegativity and OCI were detected in 66.7 % and 20 % respectively, of the studied cases (group I). OCI was more evident in Hodgkin lymphoma and thalassemia. A significant increase in AST activity was observed in the seronegative and OCI groups and in ALT and AST in HCV-seronegative or OCI and negative HCV patients (p ≤ 0.05). Seronegativity and OCI are a significant clinical problem in patients with hematological disorders, warranting wider use of molecular tests combined with periodic evaluations of liver functions for diagnostic purposes.

    Prevalence of pulmonary arterial hypertension (PAH) was studied by Echocardiography and Doppler in 43 splenectomised patients with various disorders 1-20 years after splenectomy. PAH was detected only in thalassemia major, intermedia, hereditary sphereocytosis and myelofibrosis groups comprising a total of 21 patients. Six patients out of 21 was found to have PAH with mean pulmonary arterial pressure of 46.28 ± 28.17 mmHg. Twenty one controls having similar duration and type of disease also were assessed for PAH in this case control study 3/21 had PAH in this control group. The difference in number of patients showing pulmonary hypertension between case and control was not statistically significant (chi-square test p = 0.29-though the difference in pulmonary arterial pressure between case and control were significantly different (t-test psideroblastic anemia, extra hepatic portal hypertension, autoimmune hemolytic anemia did not show PAH after splenectomy even years after the procedure PAH following splenectomy is common after certain disorders and control patients with these diseases have tendency to develop PAH even without splenectomy. Pulmonary thromboembolism may be an important pathophysiological mechanism leading to this condition. Patients having hemolytic anemia and myelofibrosis should have regular evaluation of pulmonary arterial pressure whether he/she has been splenectomised or not. This is particularly important as availability of phosphodiesterase inhibitors like sildenafil allows one to manage these cases.

    Background There has been continuous debate as to whether Y chromosome loss is an age related phenomenon or a cytogenetic marker indicating a malignant change. This study aimed to investigate the frequency of Y chromosome loss in the specific patients in order to determine whether it is an age related phenomena or a cytogenetic marker indicating a malignant change.Methods Five hundred and ninety-two male patients with a median age of 59 years old (22-95 years) were included in this study. These patients were divided into two groups: the study group, including 237 patients who had hematological disorders included myeloproliferative disorder (MPD), myelodysplastic syndrome (MDS), acute myeloid leukemia (AML),chronic myeloid leukemia (CML), multiple myeloma (MM), and lymphoma and the control group including 355 patients with no evidence of hematological disease. Both conventional cytogenetics and fluorescence in situ hybridization using DNA probes specific for the centromere of chromosomes X or Y were performed according to our standard laboratory protocols.Results Twenty-four out of 237 patients with hematological disorders (10.1%) had Y chromosome loss. Of these 24patients, 2 patients had AML (5.0% of all AML patients), 2 patients had CML (5.7% of all CML patients), 2 patients had MPD (8.0% of all MPD patients), 3 patients had MM (10.0% of all MM patients), 5 patients had lymphoma (10.6% of all lymphoma patients) and 10 patients had MDS (16.7% of all MDS patients). Twenty-one out of these 24 patients had a loss of Y chromosome as the sole anomaly and the remaining three had a loss of Y chromosome accompanied with otherstructural changes detected by conventional cytogenetic analysis. Fluorescence in situ hybridization (FISH) analysis confirmed the routine cytogenetic results. All 24 patients had a loss of Y chromosome with a range of 17.5%-98.5% of cells. Two of the patients, one with AML and another with CML, had karyotype and FISH testing done both at the initial

    Synopsis of the introductory paragraph of the DEGRO consensus S2e-guideline recommendations for the radiotherapy of benign disorders, including physical principles, radiobiological mechanisms, and radiogenic risk. This work is based on the S2e-guideline recommendations published November 14, 2013. The basic principles of radiation physics and treatment delivery, evaluation of putative underlying radiobiological mechanisms, and the assessment of genetic and cancer risk following low-dose irradiation will be presented. Radiation therapy of benign diseases is performed according to similar physical principles as those governing treatment of malignant diseases in radiation oncology, using the same techniques and workflows. These methods comprise usage of orthovoltage X-ray units, gamma irradiation facilities, linear accelerators (LINACs), and brachytherapy. Experimental in vitro and in vivo models recently confirmed the clinically observed anti-inflammatory effect of low-dose X-irradiation, and implicated a multitude of radiobiological mechanisms. These include modulation of different immunological pathways, as well as the activities of endothelial cells, mono- and polymorphonuclear leukocytes, and macrophages. The use of effective dose for radiogenic risk assessment and the corresponding tumor incidence rate of 5.5 %/Sv are currently controversially discussed. Some authors argue that the risk of radiation-induced cancers should be estimated on the basis of epidemiological data. However, such data are rarely available at present and associated with high variability. Current radiobiological studies clearly demonstrate a therapeutic effectiveness of radiation therapy used to treat benign diseases and implicate various molecular mechanisms. Radiogenic risks should be taken into account when applying radiation treatment for benign diseases. (orig.)

    2013-01-01

    Full Text Available Obesity and the associated metabolic syndrome are among the most common and detrimental metabolic diseases of the modern era, affecting over 50% of the adult population in the United States. Surgeries designed to promote weight loss, known as bariatric surgery, typically involve a gastric bypass procedure and have shown high success rates for treating morbid obesity. However, following gastric bypass surgery, many patients develop chronic anemia, most commonly due to iron deficiency. Deficiencies of vitamins B1, B12, folate, A, K, D, and E and copper have also been reported after surgery. Copper deficiency can cause hematological abnormalities with or without neurological complications. Despite oral supplementation and normal serum concentrations of iron, copper, folate, and vitamin B12, some patients present with persistent anemia after surgery. The evaluation of hematologic disorders after gastric bypass surgery must take into account issues unique to the postsurgery setting that influence the development of anemia and other cytopenias. In this paper, the clinical characteristics and differential diagnosis of the hematological disorders associated with gastric bypass surgery are reviewed, and the underlying molecular mechanisms are discussed.

    The translocation t(8;21), leading to a fusion between the RUNX1 gene and the RUNX1T1 locus, was the first chromosomal translocation identified in cancer. Since the first description of this balanced rearrangement in a patient with acute myeloid leukemia (AML) in 1973, RUNX1 translocations and point mutations have been found in various myeloid and lymphoid neoplasms. In this chapter, we summarize the currently available data on the clinical relevance of core binding factor gene alterations in hematological disorders. In the first section, we discuss the prognostic implications of the core binding factor translocations RUNX1-RUNX1T1 and CBFB-MYH11 in AML patients. We provide an overview of the cooperating genetic events in patients with CBF-rearranged AML and their clinical implications, and review current treatment approaches for CBF AML and the utility of minimal residual disease monitoring. In the next sections, we summarize the available data on rare RUNX1 rearrangements in various hematologic neoplasms and the role of RUNX1 translocations in therapy-related myeloid neoplasia. The final three sections of the chapter cover the spectrum and clinical significance of RUNX1 point mutations in AML and myelodysplastic syndromes, in familial platelet disorder with associated myeloid malignancy, and in acute lymphoblastic leukemia.

    Recently defined consensus criteria for the diagnosis of neuromyelitis optica spectrum disorders (NMOSD) allow establishing the diagnosis in patients without elevated AQP4-Ab and optic nerve involvement. According to the new extended definition, NMOSD is closely associated with extensive spinal cord inflammation occurring in the course of systemic autoimmune diseases as sarcoidosis or lupus erythematodes. NMOSD occurring in the course of hematological disease have not yet been reported in the literature. A 38 year old male subsequently developed thrombocytopenia, hemolytic anemia and agranulocytosis over a 23 month period. Three months after an episode of agranulocytosis, he noticed ascending sensory disturbances and progressive weakness of his legs. Within two days, symptoms worsened to give almost complete paraplegia and loss of sensation below a midthoracic level. MRI revealed signal hyperintensity and edema in T2-weighted sequences reaching from the 2nd cervical to the 9th thoracic vertebral body. Two years later, he developed a second episode with lesions in the spinal cord and periventricular areas of brain stem and thalamus. The relapsing time course and the topographical pattern of central nervous system lesions restricted to axial brain structures and the spinal cord fulfill the criteria that have recently been defined for AQP4-Ab-negative NMO-spectrum disease. Systematic studies on the association of hematological autoimmune phenomena and spinal cord disease are needed to clarify whether this coincidence is just a casual phenomenon or whether it points to a yet undiscovered but perhaps therapeutically interesting link of immunological mechanisms affecting both organ systems.

    The purpose of this study was to examine the late adverse effects of childhood hematological disorders treated with chemotherapy and radiotherapy including whole cranial irradiation at Sapporo Medical University Hospital. Twenty-eight patients were treated with chemotherapy and 18-24 Gy of prophylactic cranial irradiation (PCI) for acute lymphoblastic leukemia (ALL), and 14 patients were treated with 3-12.8 Gy of total body irradiation (TBI) and bone marrow transplantation (BMT) for ALL, acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), myelodysplastic syndrome (MDS), malignant lymphoma, and aplastic anemia (AA). Age at diagnosis ranged from 2 to 15 years old, and 28 were males and 14 were females. All patients were disease-free more than 2 years after diagnosis. Of 42 patients, 4 patients had decreased height (less than -2 S.D.), 3 patients required hormone replacement therapy, 2 patients had mental retardation, 3 patients had leukoencephalopathy, and 1 patient had a second malignancy. Except for the cases of decreased height, 3 of 7 late adverse effects were occurred in patients who had relapse of disease, and the risk of the adverse effects seemed to be higher for those patients whose doses of PCI were 22 Gy or more, or who received an additional craniospinal irradiation due to relapse of disease, and 18 Gy of PCI did not increase the risk of adverse effects.

    Full Text Available Background/AimsPortal-vein thrombosis (PVT develops in 10-25% of cirrhotic patients and may aggravate portal hypertension. There are few data regarding the effects of anticoagulation on nonmalignant PVT in liver cirrhosis. The aim of this study was to elucidate the safety, efficacy, and predictors of response to anticoagulation therapy in cirrhotic patients.MethodsPatients with liver cirrhosis and nonmalignant PVT were identified by a hospital electronic medical record system (called BESTCARE. Patients with malignant PVT, Budd-Chiari syndrome, underlying primary hematologic disorders, or preexisting extrahepatic thrombosis were excluded from the analysis. Patients were divided into two groups (treatment and nontreatment, and propensity score matching analysis was performed to identify control patients. The sizes of the thrombus and spleen were evaluated using multidetector computed tomography.ResultsTwenty-eight patients were enrolled in this study between 2003 and 2014: 14 patients who received warfarin for nonmalignant PVT and 14 patients who received no anticoagulation. After 112 days of treatment, 11 patients exhibited significantly higher response rates (complete in 6 and partial in 5 compared to the control patients, with decreases in thrombus size of >30%. Compared to nonresponders, the 11 responders were older, and had a thinner spleen and fewer episodes of previous endoscopic variceal ligations, whereas pretreatment liver function and changes in prothrombin time after anticoagulation did not differ significantly between the two groups. Two patients died after warfarin therapy, but the causes of death were not related to anticoagulation.ConclusionsWarfarin can be safely administered to cirrhotic patients with nonmalignant PVT. The presence of preexisting portal hypertension is a predictor of nonresponse to anticoagulation.

    Accessory spleens of 1.5 cm in size were preoperatively identified by the combined use of computerized tomography and splenic scintigraphy in two patients with hematologic diseases. After the accessory spleen had been removed from the first patient, who had persistent hereditary spherocytosis and had undergone a splenectomy 15 months before, a postoperative decrease in hyperbilirubinemia was noted. In the other patient who had idiopathic thrombocytopenic purpura, a successful accessory splenectomy was done at the same time as her splenectomy, and was followed by 6 months' complete remission. These events indicate that preoperative investigations using computerized tomography and scintigraphy are indispensable for ruling out an accessory spleen in those patients for whom splenectomy needs to be done in order to alleviate hematologic disorders.

    Full Text Available Positive psychological constructs have been given increasing attention in research on the coping resources of cancer-related distresses. However, little research is available on posttraumatic stress disorder (PTSD in patients with hematological malignancies. The purposes of this study were to assess the prevalence of PTSD symptoms and to explore the associations of perceived social support (PSS, hope, optimism and resilience with PTSD symptoms among Chinese patients with hematological malignancies.A cross-sectional study was conducted during the period from July 2013 through April 2014. A total of 225 inpatients with hematological malignancies, which were eligible for the study, completed the Post-traumatic Stress Checklist-Civilian Version, Multidimensional Scale of Perceived Social Support, Adult Hope Scale, Life Orientation Scale-Revised, and Resilience Scale. Hierarchical regression analysis was performed to explore the correlates of PTSD symptoms.Overall, the prevalence of PTSD symptoms was 10.7%. Initially, PSS was negatively associated with PTSD symptoms (β = -0.248, P < 0.01. However, when positive psychological variables were added, optimism was negatively associated with PTSD symptoms (β = -0.452, P < 0.01, and gender had a significant effect on PTSD symptoms. Women were more vulnerable to these symptoms than men (β = 0.123, P < 0.05. When the analysis was performed separately by gender, only optimism showed a significantly negative association with PTSD symptoms in both men (β = -0.389, P < 0.01 and women (β = -0.493, P < 0.01.Some patients with hematological malignancies suffer from PTSD symptoms. The positive effects of PSS and optimism on PTSD symptoms suggest that an integrated approach to psychosocial intervention from both external and internal perspectives could have practical significance. Gender difference should be considered in developing potential interventions in reducing cancer-related PTSD symptoms.

    Many antiepileptic drugs (AEDs) are associated with hematological disorders that range from mild thrombocytopenia or neutropenia to anemia, red cell aplasia, until bone marrow failure. Fortunately, potentially fatal hematological disorders such as aplastic anemia are very rare. This review investigates hematological effects associated with classic and newer AEDs: a PubMed search indexed for MEDLINE was undertaken to identify studies in adults, children and animals using the name of all anticonvulsant drugs combined with the terms "hematological disease" and "hematological abnormalities" as key words. The most common hematological alterations occur with older AEDs than newer. Indeed, careful hematological monitoring is needed especially using carbamazepine, phenytoin and valproic acid. The pathogenetic mechanisms are still unknown: they seem to be related to an immunological mechanism, but drugs pharmacokinetics and pharmacodynamics interactions may also play an important role. Further research is needed to assess the real pathogenetic mechanism at the basis of hematological complications caused by AEDs.

    It is well known that Helicobacter pylori infection is associated with many nonmalignant disorders such as gastritis, peptic ulcer, gastroesophageal reflux disease (GERD), gastric polyp, nonsteroidal anti-inflammatory drug (NSAID)/aspirin-induced gastric injury, and functional dyspepsia. In 2008, interesting articles on the association of H. pylori infection with these disorders were presented, some of which intended to reveal the mechanisms of inter-individual differences in response to H. pylori infection, and have demonstrated that genetic differences in host and bacterial factors as well as environmental factors account for these differences. A decline in the occurrence of peptic ulcer related to H. pylori was confirmed. An inverse relationship between H. pylori infection and GERD was also confirmed but the impact of gastric atrophy on the prevention of GERD remained debatable. For NSAID-induced gastric injury, eradication of H. pylori infection has been recommended. During this year, eradication of H. pylori infection was recommended for patients treated with antiplatelet therapy as well as aspirin and NSAID. It was also reported that for patients with functional dyspepsia, eradication of H. pylori offers a modest but significant benefit.

    In 19 cases of secondary hematologic disorders in patients previously treated for Hodgkin's disease, chromosome aberrations were analyzed in relation to the type of previous chemo- and/or radiotherapy, age of the patients, histopathologic features of the Hodgkin's disease at diagnosis, time interval between the treatment and the occurrence of the secondary disorder, and survival. The karyotype was of significant prognostic value when three cytogenetic groups were considered: patients with normal karyotypes; patients with aberrations of chromosome 7 as the sole anomaly; and patients with complex rearrangements and translocations. The last group showed the lowest rate of survival. Bone marrow transplantation was successful in two patients with a normal karyotype.

    Full Text Available Objective: The present work was undertaken in order to investigate the effects of right-unilateral lesion of substantia nigra neurons by means of 6- hydroxydopamine (6-OHDA, a dopaminergic-selective neurotoxin, on hematological parameters in rats. The primary reason for the using of rat model of Parkinson’s disease was the interest regarding the role of the central dopaminergic system in hematopoiesis regulation because some neurological diseases like Parkinson’s disease are well-correlated with anemia associated with autonomic dysfunction in rats.Material and Methods: Thirty male Wistar rats weighing 200 ± 50 g at the start of the experiment were used. The substantia nigra was right-unilateral lesioned by stereotaxic microinjections of 8 micrograms (free base 6-OHDA, dissolved in 4 µl physiological saline containing 0.1% ascorbic acid, administered through the Hamilton microsyringe over 4.50 minutes. 7 days after neurosurgery, we assessed the total number of white blood cells (WBC, the total number of red blood cells (RBC, hemoglobin level and the erythrocyte indexes (mean cell volume, MCV and mean cell hemoglobin, MCH.Hematological parameters were assayed by a COULTER® Ac◊T 5diff CP-precision instruments for hematology research.Results: 6-OHDA treatment induced a significantly decrease of white blood cells (p<0.03, red blood cells (p<0.01, hemoglobin level (p<0.02 comparative with sham-operated rats. By contrast, in the 6-OHDA-lesioned rats the erythrocyte indexes (mean cell volume, MCV (p<0.04; mean cell hemoglobin, MCH (p<0.01 were significantly enhanced comparative with sham-operated rats.Conclusion: On the whole, the obtained data indicate the important role of the central dopaminergic system in the regulation of erythrocyte dynamics.

    Anemia and macrocytosis are well-defined expected hematologic findings of vitamin B12 and folate deficiency; however, some previous studies did not show a significant association of subnormal B12 with anemia and macrocytosis. We retrospectively analyzed 17 713 laboratory patient records to evaluate vitamin B12 and folate levels in relation to anemia and macrocytosis. In an age- and sex-adjusted logistic regression model, low B12 status but not marginal B12 status was significantly associated with anemia [ORs respectively, 1.291 (95% CI, 1.182-1.410), 1.022 (95% CI, 0.943-1.108)] and macrocytosis [ORs, respectively, 3.853 (95% CI, 3.121-4.756), 1.031 (95% CI, 0.770-1.381)]. Also low folate status but not marginal folate status was significantly associated with anemia [adjusted ORs, respectively, 1.819 (95% CI, 1.372-2.411), 1.101 (95% CI, 0.931-1.301)] and macrocytosis [adjusted ORs, respectively, 2.945 (95% CI, 1.747-4.965), 1.228 (95% CI, 0.795-1.898)]. Our results show that increased anemia and macrocytosis are observed at values below commonly used B12 lower-reference thresholds. Determining a hematologic cutoff value may help physicians in clinical practice. © 2013 John Wiley & Sons Ltd.

    Full Text Available In recent years, the surprising progress made in other areas of hematology (advances in the understanding of leukemogenesis, improved transplant techniques has been conspicuously absent in the management of hematologic emergencies. And yet, every step toward greater knowledge, every new treatment option will be of little value unless we are able to manage the acute complications of hematologic diseases. These complications are better defined as hematologic emergencies, and they are characterized by a high rate of mortality. This review is based on a search of the literature that was initially confined to articles published in the journal Hematology from 2000 to 2009. The search was then extended to the Cochrane Library and to Pub Med in February 2010 with the following Keywords emergencies; urgencies; hematology. The same key words were employed in a search of the archives of Blood and the New England Journal of Medicine from 2000 to 2010. The results confirm that hematologic emergencies can be caused by hematologic malignancies as well as by non-neoplastic hematologic diseases. Within the former category; this review examines the causes; manifestations; treatment and prevention of disseminated intravascular coagulation; superior vena caval syndrome; spinal cord compression; tumor lysis syndrome; hyperleukocytosis; and hypercalcemia. We also review emergency situations associated with non-neoplatic haematological diseases; such as thrombotic thrombocytopenic purpura; drug-induced hemolytic anemia; and acute sickle-cell crisis.

    The aim of this study was to assess the blood profiles in female camels affected with common reproductive disorders. Estradiol-17beta (E(2)), progesterone (P(4)), thyroxin (T(4)), zinc (Zn), copper (Cu), calcium (Ca), phosphorus (P), magnesium (Mg), cholesterol, glucose, triglycerides, total protein, albumin, globulin, hematocrite, and total and differential white blood cell counts (WBC) were determined in blood of female camels affected with endometritis (n=15), vaginal adhesions (n=15), and ovarian cysts (n=15). Normal cyclic animals were used as controls (n=15). Diagnosis of reproductive disorders was based on transrectal palpation, ultrasonographic examination, and exploration of the vagina. Increased WBC counts (P=0.03) and a tendency for neutrophelia (P=0.05) were noted in female camels with vaginal adhesions. These animals were also characterized by having higher concentration of serum P(4) (P=0.0001), T(4) (P=0.001) and total protein (P=0.007), in comparison with female camels with endometritis, ovarian cysts, or controls. Animals having ovarian cysts with thin walls and homogenous hypoechogenic contents had greater serum E(2) (P=0.001) and P(4) (P=0.0001) than those having ovarian cysts with thick walls and non-homogenous echogenic contents. Animals with endometritis, vaginal adhesions, and ovarian cysts revealed lower serum Zn concentration than that of control group (P=0.003). Other blood parameters did not differ significantly compared to controls. In conclusion, this is the first report characterizing blood constituents in female camels with various reproductive disorders. These profiles may be valuable in clarifying the etio-pathogenesis of these disorders.

    Objective. Drugs can induce almost the entire spectrum of hematologic disorders, affecting white cells, red cells, platelets, and the coagulation system. This paper aims to emphasize the broad range of drug-induced hematological syndromes and to highlight some of the newer drugs and syndromes. Methods. Medline literature on drug-induced hematologic syndromes was reviewed. Most reports and reviews focus on individual drugs or cytopenias. Results. Drug-induced syndromes include hemolytic anemias, methemoglobinemia, red cell aplasia, sideroblastic anemia, megaloblastic anemia, polycythemia, aplastic anemia, leukocytosis, neutropenia, eosinophilia, immune thrombocytopenia, microangiopathic syndromes, hypercoagulability, hypoprothrombinemia, circulating anticoagulants, myelodysplasia, and acute leukemia. Some of the classic drugs known to cause hematologic abnormalities have been replaced by newer drugs, including biologics, accompanied by their own syndromes and unintended side effects. Conclusions. Drugs can induce toxicities spanning many hematologic syndromes, mediated by a variety of mechanisms. Physicians need to be alert to the potential for iatrogenic drug-induced hematologic complications. PMID:19960059

    2012-04-01

    Full Text Available Medical Genetics over the past few decades have emerged as an important and powerful medical specialty with increasing appreciation of its role and function in the biomedical sciences. This emergence is related to a great extent to the progress in the Human Genome Project, which promises wide-ranging applications in the diagnosis, treatment and prevention of human diseases. Nevertheless, the discussion on the role of genetics as the preventive medicine and public health care also lead to ethical, legal and social concerns about general applicability of genetic testing in the ethnic communities. The interpretation of prevention in the context of genetic diseases leads to the unavoidable discussions of genetic engineering, stem cell transplantation, prenatal diagnosis and selective termination of pregnancy, as well as broader concerns about discrimination in health care coverage, gender bias, employment and insurance in the society. In Indian communities where consanguineous marriage is widely practiced, recessive/x-linked genetic disorders such as sickle cell disease and beta-thalassemia, will continue to gain greater prominence in the overall spectrum of ill health. Developing an understanding of these changes will require a wide-ranging and multidisciplinary investigative approach for which public health genetics is ideally suited to conditions in Odisha.

  13. The importance of studying inherited hematological disorders in ancient Anatolian populations

    Full Text Available Before analysis of DNA from ancient remains was possible, anthropologists studied evolution and migration patterns using data obtained from population genetic studies on modern populations combined with data obtained from morphological evaluations of ancient remains. Currently, DNA analysis of ancient populations is making a valuable contribution to these efforts. Researchers that perform ancient DNA analysis prefer to study polymorphisms on the Y chromosome or mitochondrial DNA because the results are easier to statistically evaluate. To evaluate polymorphisms on diploid genomes, which are more informative, only mutations that have been extensively examined in modern populations should be chosen. The most extensively evaluated mutations are those related to prevalent inherited disorders. As such, beta-thalassemia, sickle cell anemia, FVL mutation of globin and the factor V genes are good candidates for DNA studies in ancient populations. These mutations are common in Anatolia, host to many civilizations since the Paleolithic period. This history makes Anatolia a good place for conducting research that could enhance our understanding of human evolution and migration patterns.

  14. Hematologic Complications of Pregnancy

    Townsley, Danielle M.

    2013-01-01

    Pregnancy induces a number of physiologic changes that affect the hematologic indices, either directly or indirectly. Recognizing and treating hematologic disorders that occur during pregnancy is difficult owing to the paucity of evidence available to guide consultants. This paper specifically reviews the diagnosis and management of benign hematologic disorders occurring during pregnancy. Anemia secondary to iron deficiency is the most frequent hematologic complication and is easily treated with oral iron formulations,; however care must be taken not to miss other causes of anemia, such as sickle cell disease. Thrombocytopenia is also a common reason for consulting the hematologist and distinguishing gestational thrombocytopenia from immune thrombocytopenia (ITP), preeclampsia, HELLP syndrome, or thrombotic thrombocytopenic purpura (TTP) is essential since the treatment differs widely. Occasionally the management of mother and infant involves the expeditious recognition of neonatal alloimmune thrombocytopenia (NAIT), a condition that is responsible for severe life-threatening bleeding of the newborn. Additionally, inherited and acquired bleeding disorders affect pregnant women disproportionately and often require careful monitoring of coagulation parameters in order to prevent bleeding in the puerperium. Finally, venous thromboembolism (VTE) during pregnancy is still largely responsible for mortality during pregnancy and the diagnosis, treatment options and guidelines for prevention of VTE during pregnancy are explored.

    Helicobacter pylori is responsible for most peptic ulcers, plays a role in functional dyspepsia and is thought by some to influence the course of gastroesophageal reflux disease. This article addresses recent studies that have been published in connection with these diseases. H. pylori-associated peptic ulcer is declining in prevalence but the incidence of perforation and bleeding remains high especially in the elderly. All H. pylori associated peptic ulcers should be treated by eradication of the infection. Dyspepsia is a common disorder that affects up to 25% of the population. About 8% of cases that are infected with H. pylori will respond to treatment of the infection. The association between H. pylori and gastroesophageal reflux disease continues to be debated, a number of studies have shown that there is a negative association between H. pylori infection and Gastroesophageal reflux disease but treatment of H. pylori has not been shown to induce reflux or to affect the response to medication. Gastric atrophy is known to extend when acid suppression is used in infected patients implying that H. pylori treatment should be used in infected patients who are to undergo long-term Proton Pump Inhibitor therapy.

  19. Hematological disorders detected in dogs infected by Hepatozoon canis in a municipality in Mato Grosso do Sul State, Brazil

    L.M. Paiz

    Full Text Available ABSTRACT A retrospective review of hematological reports of nine dogs detected with Hepatozoon canis infection by microscopic examination of blood smears in a laboratory in the municipality of Dourados, Mato Grosso do Sul, Brazil was conducted. This study aimed to evaluate the hematological profile of these infected dogs, in addition to the occurrence of coinfections with other agents that infect blood cells, since studies concerning canine hepatozoonosis in Brazil are scarce and there are some divergences regarding H. canis infection that still require a resolution. The nine cases of H. canis infection were identified among all dogs examined at the studied laboratory in 2009 and 2010, with an occurrence of 7/1,192 (0.59%; 95% CI 0.15 - 1.02% positive dogs in the first year and 2/1,313 (0.15%; 95% CI 0.02 - 0.55% cases in 2010. The analysis of the hematological reports showed an occurrence of coinfection between H. canis and other agents in two (2/9; 22.22%; 95% CI 2.81 - 60.00% dogs, one with E. canis and another with Babesia spp. (1/9; 11.11%; 95% CI 0.28 - 48.24%. Only the blood test of one dog had no alterations, based on reference values. Anemia was the most frequent hematological alteration (6/9; 66.67%; 95% CI 29.93 - 92.51%. Although the occurrence of H. canis infection was low, significative hematological alterations were observed in most infected dogs. Coinfection with Babesia spp. and E. canis was detected in two dogs and the hematological alterations cannot be attributed exclusively to H. canis in these animals. Longitudinal studies would be of fundamental importance to determine the causality of these alterations. These results highlight the importance of differential diagnosis in dogs when there is clinical suspicion of infection by hemoparasites, since the hematological changes in dogs infected by H. canis are quite variable.

  20. Opioid Therapy for Chronic Nonmalignant Pain

    Directory of Open Access Journals (Sweden)

    Russell K Portenoy

    1996-01-01

    Full Text Available Long term administration of an opioid drug for chronic nonmalignant pain continues to be controversial, but is no longer uniformly rejected by pain specialists. This is true despite concerns that the regulatory agencies that oversee physician prescribing of opioid drugs continue to stigmatize the practice. The changing clinical perspective has been driven, in part, by widespread acknowledgement of the remarkably favourable outcomes achieved during opioid treatment of cancer pain. These outcomes contrast starkly with popular teaching about chronic opioid therapy and affirm the potential for prolonged efficacy, tolerable side effects, enhanced function associated with improved comfort and minimal risk of aberrant drug-related behaviours consistent with addiction. A large anecdotal experience in populations with nonmalignant pain suggests that these patients are more heterogeneous and that opioid therapy will greatly benefit some and will contribute to negative outcomes for others. The few controlled clinical trials that have been performed support the safety and efficacy of opioid therapy, but have been too limited to ensure generalization to the clinical setting. A critical review of the medical literature pertaining to chronic pain, opioid pharmacology and addiction medicine can clarify misconceptions about opioid therapy and provide a foundation for patient selection and drug administration. The available data support the view that opioids are no panacea for chronic pain, but should be considered in carefully selected patients using clinically derived guidelines that stress a structured approach and ongoing monitoring of efficacy, adverse effects, functional outcomes and the occurrence of aberrant drug-related behaviours.

    Avian veterinarians often rely heavily on the results of various diagnostic tests, including hematology results. As such, cellular identification and evaluation of the cellular response are invaluable tools that help veterinarians understand the health or condition of their patient, as well as to monitor severity and clinical progression of disease and response to treatment. Therefore, it is important to thoroughly understand how to identify and evaluate changes in the avian erythron and leukon, as well as to interpret normal and abnormal results.

    Full Text Available Chronic non malignant pain is always a therapeutic challenge of great significance because a inappropriate and insufficient treatment is able to reduce the life’s quality of the patients. Many therapeutic strategies were used to solve these issues, no one exhaustive. In the treatment of cancer pain, opiates use is common, is not the same for the chronic non-malignant pain. The fear of possible side effects (addiction, tolerance, respiratory depression restrain the therapist to apply this remedy. The aim of our work is to demonstrate how a correct application of the opiates in patients with chronic benign pain is not only possible but also desirable to relieving the pain and improving the quality of life.

    Bone marrow examination is an indispensable diagnostic tool to evaluate neoplastic and non neoplastic hematological diseases. To compare bone marrow aspirate with trephine biopsy in hematological disorders. To determine the optimum trephine preprocessing length in lymphoma infiltration. Diagnostic comparison was done between simultaneous bone marrow aspirates and trephine biopsies in 449 patients. Biopsies were fixed in formalin, decalcified in 5.5% EDTA and routinely processed. Concordance rates and validity parameters for aspirate were calculated. Three deeper sections of trephine biopsy, cut at 0.1-0.2 mm intervals, were assessed for lymphoma involvement. Proportion of biopsies showing marrow infiltration by lymphoma cells was plotted against trephine length and correlation was assessed. Aspirate had a high sensitivity for acute leukemia (89.4%) and multiple myeloma (88.5%), moderate for NHL (67.6%) and nonhematopoietic metastases (58.3%) and low for aplastic anemia (38.5%) and Hodgkin lymphoma (5%). Aspirate has no role in granulomatous myelitis and myelofibrosis. Lymphoma positivity increased with trephine length, with maximum positivity (68.9%) seen in 17-20 mm group and no further gain beyond 20 mm. (lymphoma positivity ≤16mm=40.3% and ≥17mm=66.1%, p=0.0011). Aspirate has a high specificity; its sensitivity depends upon the type of disease. Apart from few conditions, in which aspirate alone is sufficient, biopsy is mandatory in most. Preprocessing trephine length of 17-20 mm examined at multiple deeper levels was found optimal for assessing lymphoma positivity.

    2010-10-01

    Full Text Available Abstract Introduction Intracranial or spinal compressive lesions due to extramedullary hematopoiesis have been reported in the medical literature. Most of the reported cases are extradural lesions or, on rare occasions, foci within another neoplasm such as hemangioblastoma, meningioma or pilocytic astrocytoma. Often these cases occur in patients with an underlying hematological disorder such as acute myelogenic leukemia, myelofibrosis, or other myelodysplastic syndromes. Such lesions have also been reported in thalassemia major. Case presentation We report the case of a 43-year-old Iranian woman in whom extramedullary hematopoiesis presented as a compressive cord lesion and then later as an intracranial lesion. Conclusions To the best of our knowledge, we document the first reported case of sacral, lumbar, thoracic and cranial involvement in the same patient with extramedullary hematopoiesis, which seems both rare and remarkable.

  7. 5. Nonmalignant diseases after the Chernobyl catastrophe.

    Science.gov (United States)

    Yablokov, Alexey V

    2009-11-01

    This section describes the spectrum and the scale of the nonmalignant diseases that have been found among exposed populations. Adverse effects as a result of Chernobyl irradiation have been found in every group that has been studied. Brain damage has been found in individuals directly exposed--liquidators and those living in the contaminated territories, as well as in their offspring. Premature cataracts; tooth and mouth abnormalities; and blood, lymphatic, heart, lung, gastrointestinal, urologic, bone, and skin diseases afflict and impair people, young and old alike. Endocrine dysfunction, particularly thyroid disease, is far more common than might be expected, with some 1,000 cases of thyroid dysfunction for every case of thyroid cancer, a marked increase after the catastrophe. There are genetic damage and birth defects especially in children of liquidators and in children born in areas with high levels of radioisotope contamination. Immunological abnormalities and increases in viral, bacterial, and parasitic diseases are rife among individuals in the heavily contaminated areas. For more than 20 years, overall morbidity has remained high in those exposed to the irradiation released by Chernobyl. One cannot give credence to the explanation that these numbers are due solely to socioeconomic factors. The negative health consequences of the catastrophe are amply documented in this chapter and concern millions of people.

    Full Text Available Respiratory viruses are a cause of upper respiratory tract infections (URTI, but can be associated with severe lower respiratory tract infections (LRTI in immunocompromised patients. The objective of this study was to investigate the genetic variability of influenza virus, parainfluenza virus and respiratory syncytial virus (RSV and the duration of viral shedding in hematological patients. Nasopharyngeal swabs from hematological patients were screened for influenza, parainfluenza and RSV on admission as well as on development of respiratory symptoms. Consecutive swabs were collected until viral clearance. Out of 672 tested patients, a total of 111 patients (17% were infected with one of the investigated viral agents: 40 with influenza, 13 with parainfluenza and 64 with RSV; six patients had influenza/RSV or parainfluenza/RSV co-infections. The majority of infected patients (n = 75/111 underwent stem cell transplantation (42 autologous, 48 allogeneic, 15 autologous and allogeneic. LRTI was observed in 48 patients, of whom 15 patients developed severe LRTI, and 13 patients with respiratory tract infection died. Phylogenetic analysis revealed a variety of influenza A(H1N1pdm09, A(H3N2, influenza B, parainfluenza 3 and RSV A, B viruses. RSV A was detected in 54 patients, RSV B in ten patients. The newly emerging RSV A genotype ON1 predominated in the study cohort and was found in 48 (75% of 64 RSV-infected patients. Furthermore, two distinct clusters were detected for RSV A genotype ON1, identical RSV G gene sequences in these patients are consistent with nosocomial transmission. Long-term viral shedding for more than 30 days was significantly associated with prior allogeneic transplantation (p = 0.01 and was most pronounced in patients with RSV infection (n = 16 with a median duration of viral shedding for 80 days (range 35-334 days. Long-term shedding of respiratory viruses might be a catalyzer of nosocomial transmission and must be considered for

    Hematological disorder is a subject that is highly specialized. The teaching for hematological disorder is facing many difficulties. Comprehensive application of a variety of teaching method, such as problem oriented teaching method, participatory teaching method, simulation teaching method and other teaching methods was put forward in this paper. Students can adapt to internship in a relatively short time by means of it. In addition, both basic and advanced knowledge were delivered to students at the same time during the clinic practice. On one side, students can be familiar with both clinical symptoms plus signs and differential diagnosis of blood disorders. On the other side, students can be familiar with latest developments. Bilingual teaching should be paid more attention in clinical practice. Finally, the medical ethics and the doctor-patient communication skills education is the basis for students to successfully complete the internship and to be qualified clinicians.%血液病学是一门专科性很强的临床学科,临床实习面临很多困难。面对困难,本文提出了问题为导向的教学方法、参与式教学方法、模拟教学法等多种教学方法综合应用,使同学在较短时间内适应并融入临床实践。本文还提出了实习中基础及前沿兼顾的方法,既让同学熟悉血液病的临床症状及体征,又讲授鉴别诊断,使同学深刻理解疾病本质;另外,根据同学掌握情况,适当介绍最新进展,进一步提高学生临床技能。在实习中,必须重视双语教学,为学生以后掌握最新进展奠定基础。最后,本文强调了医德及医患沟通教育是学生顺利完成实习及成为合格临床医师的前提。

    With the introduction of genomic technologies, more hereditary cancer syndromes with hematologic malignancies are being described. Up to 10% of hematologic malignancies in children and adults may be the result of an underlying inherited genetic risk. Managing these patients with hereditary hematologic malignancies, including familial leukemia, remains a clinical challenge because there is little information about these relatively rare disorders. This article covers some of the issues related to the diagnosis and interpretation of variants associated with hereditary hematologic malignancies, including the importance of an accurate family history in interpreting genetic variants associated with disease. The challenges of screening other family members and offering the most appropriate early malignancy detection is also discussed. We now have a good opportunity to better define hereditary cancer syndromes with associated hematologic malignancies and contribute to clinically effective guidelines.

    The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at €23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap.The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders.The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

    We analyzed the incidence, clinicopathological features, risk factors and prognosis of patients with EBV-associated post-transplant lymphoproliferative disorder (EBV-PTLD) in 288 adults undergoing umbilical cord blood transplantation (UCBT) at a single institution. Twelve patients developed proven EBV-PTLD at a median time of 73 days (range, 36-812). Three-year cumulative incidence (CI) of EBV-PTLD was 4.3% (95% CI: 1.9-6.7). All patients presented with extranodal involvement. Most frequently affected sites were the liver, spleen, central nervous system (CNS), Waldeyer's ring and BM in 7, 6, 4, 3 and 3 patients, respectively. One patient had polymorphic and 11 had monomorphic EBV-PTLD (7 diffuse large B-cell lymphomas not otherwise specified, 4 plasmablastic lymphomas). We confirmed donor origin and EBV infection in all histological samples. EBV-PTLD was the cause of death in 11 patients at a median time of 23 days (range, 1-84). The 3-year CI of EBV-PTLD was 12.9% (95% CI: 3.2-22.5) and 2.6% (95% CI: 0.5-4.7) for patients receiving reduced-intensity conditioning (RIC) and myeloablative conditioning, respectively (P<0.0001). In conclusion, adults with EBV-PTLD after UCBT showed frequent visceral and CNS involvement. The prognosis was poor despite routine viral monitoring and early intervention. An increased risk of EBV-PTLD was noted among recipients of RIC regimens.

  15. Nonnarcotic analgesics and tricyclic antidepressants for the treatment of chronic nonmalignant pain.

    Richlin, D M

    Chronic nonmalignant pain is often characterized by multiple treatment failures, a pattern of maladaptive behavior, and depression. Often there is a history of inappropriate and excessive use of medications for pain. Prior and ongoing use of narcotics and sedatives acts to compound and aggravate the chronic pain syndrome. A first step in treatment is controlled withdrawal of these agents. Nonnarcotic analgesics, NSAIDs, and tricyclic antidepressants are commonly employed in patients with chronic pain. Effective use of these agents requires understanding of their pharmacokinetic and pharmacodynamic properties. Use of a fixed-time schedule is necessary to achieve an effective, sustained therapeutic response. Careful patient education and monitoring for side effects and toxicity are necessary, particularly in the elderly and patients with coexisting medical disorders. Incidence of side effects and toxicity may be reduced by choice of drug and modification of dosing regimen. Nonnarcotic analgesics, TCAs, and NSAIDs are seldom effective by themselves in resolving the pain and distress of patients with chronic nonmalignant pain. This is particularly true when maladaptive behavior coexists. A comprehensive multimodal pain management program encompassing additional pain-relieving strategies and behavior-modifying techniques should be considered and utilized in conjunction with medication.

    Autoimmune hematological diseases (AHDs) may occur after allogeneic hematopoietic stem cell transplantation (HSCT), but reports on these complications in large cohorts of pediatric patients are lacking. Between 1998 and 2011, 1574 consecutive children underwent allogeneic HSCT in 9 Italian centers. Thirty-three children (2.1%) developed AHDs: 15 autoimmune hemolytic anemia (45%), 10 immune thrombocytopenia (30%), 5 Evans' syndrome (15%), 2 pure red cell aplasia (6%), and 1 immune neutropenia (3%). The 10-year cumulative incidence of AHDs was 2.5% (95% confidence interval, 1.7 to 3.6). In a multivariate analysis, the use of alternative donor and nonmalignant disease was statistically associated with AHDs. Most patients with AHDs (64%) did not respond to steroids. Sustained complete remission was achieved in 87% of cases with the anti-CD20 monoclonal antibody (rituximab). Four patients (9%) (1 autoimmune hemolytic anemia, 1 Evans' syndrome, 2 immune thrombocytopenia) died at a median of 87 days after AHD diagnosis as a direct or indirect consequence of their disorder. Our data suggest that AHDs are a relatively rare complication occurring after HSCT that usually respond to treatment with rituximab.

    Oncology nurses working in ambulatory care often encounter patients with nonmalignant hematologic disorders because the specialties of hematology and oncology are closely entwined. A variety of nonmalignant hematologic disorders can evolve into blood malignancies; therefore, close surveillance of nonmalignant hematologic disorders in an oncology/hematology clinic is important for early detection of malignancy. Monoclonal gammopathy of undetermined significance (MGUS) is one nonmalignant, hematologic disorder that is usually aproblematic; however, it can evolve into a blood malignancy such as multiple myeloma or be associated with other chronic conditions. This article provides an overview of MGUS with a focus on implications for the oncology nurse and patient education.

    ObjectiveTo analyze the characteristics of hematological disorders in patients with systemic lupus erythematosus (SLE) and its clinical signiifcance.Method150 cases of diagnosed SLE patients in our hospital from January 2011 to June 2014 were enrolled into the study to investigate their characteristics of hematological disorders. All patients were divided into control group (without hematological disorders) and observation group (hematological disorders). The activity of the disease, the positive rate of anti-extractable unclear antigen (ENA) antibodies and concentrations of immunological factors were detected and compared.ResultAmong the 150 SLE patients, 116 cases (77.3%) had hematological disorders. And anemia in 91 cases (60.7%), leukopenia 49 cases (32.7%), thrombocytopenia 58 cases (38.7%). Compared with control group, cases with no activity were statistically less and cases with mild activity, moderate activity, severe activity were statistically more in observation group (P0.05). As to immunological factors, concentration of IL-2, IL-6 and TNF-α in observation group were statistically higher than that in control group respectively (P<0.05).ConclusionHematological disorders are common in SLE patients, of which anemia is the most common ifnding. At the same time, SLE patients with hematological disorders show a higher degree of severity of the activity, higher positive rates of associated antibodies and higher concentrations of immunological factors, which threatens patients’ health and life more.%目的:分析系统性红斑狼疮(systemic lupus erythematosus,SLE)患者血液系统损害的特点,并探讨其临床意义。方法回顾性分析2011年1月至2014年6月本院确诊的150例SLE患者的临床资料,总结其血液系统损害特点。将患者分为对照组(无血液系统损害)和观察组(血液系统损害),比较两组患者疾病活动情况、可提取性核抗原(ENA)抗体阳性率及免

    Although a complete blood count is part of the evaluation before the use of electroconvulsive therapy (ECT), there are no known hematological contraindications for the procedure. A preliminary study was done on 31 randomly selected psychiatric patients (chronic schizophrenia, n=10; acute depression, n=8; acute mania, n=6; acute psychosis, n=6; delusional disorder, n=1) receiving ECT to study its hematological effects. Blood samples were drawn just before and 0, 1 and 2 h after ECT. Hemoglobin (Hb%), total and differential leukocyte count (TLC and DLC), red blood cell (RBC) count, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and platelet count were measured on a fully automated hematology analyzer (Sysmex K-1000). Significant changes were found in TLC, percentage of polymorphs and lymphocytes, and Hb%. Changes in other parameters were not statistically significant. More such studies are needed to substantiate these observations and to understand the mechanism and implication of these effects.

    Full Text Available Introduction. Long term exposure to trace amounts of anesthetic vapors and gases may produce hematologic and hepatic disorders in human. Since operating room (OR staffs are exposed to these agents, we decided to study their hematopoietic and hepatic systems in comparison with ordinary ward staffs. Methods. Seventy staffs from OR were compared with a matched similar number of ward staffs about their hematologic and hepatic laboratory findings in a historical cohort study. Findings. Mean of leukocyte and platelet counts were significantly lower in OR staffs, but in normal range. Mean of monocyte count was significantly higher in OR staffs. No significant differences were found between two groups for other hepatic and hematologic tests. Fatigue and headache were reported in OR staffs more than others. Conclusion. These findings may warn a risk to OR staffs but, it is not clear and requires further controlled studies.

    Full Text Available Background: Presently, the graphical data of blood cells (histograms and cytograms or/ scattergrams that they are usually available in all modern automated hematology analyzers are an integral a part of automated complete blood count (CBC. To find incorrect results from automated hematology analyzer and establish the samples that require additional analysis, Laboratory employees will use those data for quality control of obtaining results, to assist identification of complex and troublesome cases. Methods: During this descriptive analytic study, in addition to erythrocyte graphs from variety of patients, referring from March 2013 to Feb 2014 to our clinical laboratory, Zagros Hospital, Kermanshah, Iran, are given, the papers published in relevant literature as well as available published manuals of automatic blood cell counters were used. articles related to the key words of erythrocyte graphs and relevant literature as well as available published manuals of automatic blood cell counters were searched from valid databases such as Springer Link, google scholar, Pubmed and Sciencedirect. Then, the articles related to erythrogram, erythrocyte histogram and hematology analyzer graphs are involved in diagnosis of hematological disorder were searched and selected for this study. Results: Histograms and different automated CBC parameter become abnormal in various pathologic conditions, and can present important clues for diagnosis and treatment of hematologic and non-hematologic disorders. In several instances, these histograms have characteristic appearances in an exceedingly wide range of pathological conditions. In some hematologic disorders like iron deficiency or megaloblastic anemia, a sequential histogram can clearly show the progressive treatment and management. Conclusion: These graphical data are often accompanied by other automated CBC parameter and microscopic examination of peripheral blood smears (PBS, and can help in monitoring and

    Full Text Available Hematology is a comprehensive discipline covering all oncological and non-oncological aspects of diseases of the blood or related organs. Hematological researchers have been pivotal in the progress which has been made in molecular diagnostics, targeted therapies, and hence personalized medicine. Besides the rapid scientific and clinical developments political and strategic issues have to be addressed: Education of medical personnel needs harmonization throughout Europe; patients all over Europe should have equal access to treatment, and further scientific progress has to be secured through funding on a national, European and international level despite economic restraints. The European Hematology Association (EHA pursues these issues with and for all European hematologists and patients.

    que mejores resultados presentó en las tres subescalas analizadas: valoración subjetiva del COS, subescala objetiva del insomnio y los que menor cantidad de fármacos consumían para dormir. También encontramos diferencia en la incidencia de ansiedad/depresión, significativamente estadística, en función del tipo de opioide, siendo de nuevo el grupo tratado con hidromorfona el que menor incidencia de afectación psíquica presentaba. No encontramos diferencias significativas en los trastornos del sueño y en la prevalencia de ansiedad-depresión en función de las otras varables: tipo de dolor, o sexo. Conclusiones: en nuestro estudio los pacientes que consumían hidromorfona presentaron mejor calidad del sueño, menor consumo de hipnóticos y un menor índice de padecer un cuadro ansioso-depresivo. Cierto es que, quizá, para corroborar estos resultados y evitar elementos que distorsionen los resultados, habrá, en próximos trabajos, que valorar la presencia de otras variables.Introduction: accompanying pain, other biologically important functions are present which are not always well recognized and which are usually called "co morbidities". One of them is sleep, although it has also been shown some correlation between the state of mood and nociception, being both states the most studied and considered as relevant in relation to chronic pain, anxiety and depression. Objective: the main objective is to evaluate the quality of sleep in patients with chronic nonmalignant pain (CNMP treated with potent opioids. As secondary objectives: To analyze the incidence of anxiety and depression in these patients and to compare the quality of sleep and incidence of anxiety-depression with different variables: type of opioid, gender, sex and type of pain. Material and methods: we considered the study universe CNMP patients treated with the same strong opioid for at least three months and were seen at the Pain Management Unit between September 2009 and march 2010.

    The hematologic evaluation of reptiles is an indispensable diagnostic tool in exotic veterinary practice. The diversity of reptile species, their characteristic physiologic features, and effects of intrinsic and extrinsic factors present unique challenges for accurate interpretation of the hemogram. Combining the clinical presentation with hematologic findings provides valuable information in the diagnosis and monitoring of disease and helps guide the clinician toward therapy and further diagnostic testing. This article outlines the normal and pathologic morphology of blood cells of reptile species. The specific comparative aspects of reptiles are emphasized, and structural and functional abnormalities in the reptilian hemogram are described.

    Hematologists have traditionally studied blood and its components by simplifying it into its components and functions. A variety of new techniques have generated large and complex datasets. Coupled to an appreciation of blood as a dynamic system, a new approach in systems hematology is needed. Systems hematology embraces the multi-scale complexity with a combination of mathematical, engineering, and computational tools for constructing and validating models of biological phenomena. The validity of mathematical modeling in hematopoiesis was established early by the pioneering work of Till and McCulloch. This volume seeks to introduce to the various scientists and physicians to the multi-faceted field of hematology by highlighting recent works in systems biology. Deterministic, stochastic, statistical, and network-based models have been used to better understand a range of topics in hematopoiesis, including blood cell production, the periodicity of cyclical neutropenia, stem cell production in response to cytokine administration, and the emergence of drug resistance. Future advances require technological improvements in computing power, imaging, and proteomics as well as greater collaboration between experimentalists and modelers. Altogether, systems hematology will improve our understanding of normal and abnormal hematopoiesis, better define stem cells and their daughter cells, and potentially lead to more effective therapies.

    Many cell types release extracellular vesicles (EVs), including exosomes, microvesicles (MVs), and apoptotic bodies, which play a role in physiology and diseases. Presence and phenotype of circulating EVs in hematological malignancies (HMs) remain largely unexplored.The aim of this study was to characterize EVs in peripheral blood of HM patients compared to healthy subjects (controls). We isolated serum EVs from patients with chronic lymphocytic leukemia (CLL), non-Hodgkin's lymphoma (NHL), Waldenstrom's macroglobulinemia (WM), Hodgkin's lymphoma (HL), multiple myeloma (MM), acute myeloid leukemia (AML), myeloproliferative neoplasms (MPNs), myelodysplastic syndromes (MDS), and controls. EVs were isolated from serum of peripheral blood by ultracentrifuge steps and analyzed by flow cytometry to define count, size, and immunophenotype. MV levels were significantly elevated in WM, HL, MM, AML, and some MPNs and, though at a lesser degree, in CLL and NHL as compared to healthy controls. HL, MM, and MPNs generated a population of MVs characterized by lower size (below 0.3 μm) when compared to controls. MVs from patients specifically expressed tumor-related antigens, such as CD19 in B cell neoplasms, CD38 in MM, CD13 in myeloid tumors, and CD30 in HL. Both total and antigen-specific count of MVs significantly correlated with different HM clinical features such as Rai stage in CLL, International Prognostic Scoring System in WM, International Staging System in MM, and clinical stage in HL. MVs may represent a novel biomarker in HMs.

    The principles of hematological dosimetry after acute or protracted whole-body irradiation are reviewed. In both cases, over-exposure is never homogeneous and the clinical consequences, viz medullary aplasia, are directly associated with the mean absorbed dose and the seriousness and location of the overexposure. The main hematological data required to assess the seriousness of exposure are the following: repeated blood analysis, blood precursor cultures, as indicators of whole-body exposure; bone marrow puncture, medullary precursor cultures and medullary scintigraphy as indicators of the importance of a local over-exposure and capacity for spontaneous repair. These paraclinical investigations, which are essential for diagnosis and dosimetry, are also used for surveillance and for the main therapeutic issues.

    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.

    2017-04-13

    RUNX1 is a member of the core-binding factor family of transcription factors and is indispensable for the establishment of definitive hematopoiesis in vertebrates. RUNX1 is one of the most frequently mutated genes in a variety of hematological malignancies. Germ line mutations in RUNX1 cause familial platelet disorder with associated myeloid malignancies. Somatic mutations and chromosomal rearrangements involving RUNX1 are frequently observed in myelodysplastic syndrome and leukemias of myeloid and lymphoid lineages, that is, acute myeloid leukemia, acute lymphoblastic leukemia, and chronic myelomonocytic leukemia. More recent studies suggest that the wild-type RUNX1 is required for growth and survival of certain types of leukemia cells. The purpose of this review is to discuss the current status of our understanding about the role of RUNX1 in hematological malignancies.

    2017-02-15

    Babesiosis, a zoonotic parasitic infection transmitted by the Ixodes tick, has become an emerging health problem in humans that is attracting attention worldwide. Most cases of human babesiosis are reported in the United States and Europe. The disease is caused by the protozoa of the genus Babesia, which invade human erythrocytes and lyse them causing a febrile hemolytic anemia. The infection is usually asymptomatic or self-limited in the immunocompetent host, or follows a persistent, relapsing, and/or life threatening course with multi-organ failure, mainly in the splenectomized or immunosuppressed patients. Hematologic manifestations of the disease are common. They can range from mild anemia, to severe pancytopenia, splenic rupture, disseminated intravascular coagulopathy (DIC), or even hemophagocytic lymphohistiocytosis (HLH). A 70 year old immunocompetent female patient living in New York City presented with a persistent fever, night sweats, and fatigue of 5 days duration. Full evaluation showed a febrile hemolytic anemia along with neutropenia and thrombocytopenia. Blood smear revealed intraerythrocytic Babesia, which was confirmed by PCR. Bone marrow biopsy was remarkable for dyserythropoiesis, suggesting possible HLH, supported by other blood workup meeting HLH-2004 trial criteria. Human babesiosis is an increasing healthcare problem in the United States that is being diagnosed more often nowadays. We presented a case of HLH triggered by Babesia microti that was treated successfully. Also, we presented the hematologic manifestations of this disease along with their pathophysiologies.

    To investigate the value of dual-energy spectral computed tomography (DESCT) for differentiating malignant vertebral tumours from non-malignancies during venous phase. This study was institutional review board-approved, and written informed consent was obtained from all patients. Thirty-seven patients were examined by DESCT during venous phase. Twenty patients had malignant vertebral tumours, 17 had non-malignant vertebral tumours. The iodine/water densities for the lesion, the lesion-to-muscle ratio, and lesion-to-artery ratio for iodine density measurements were calculated and compared between the two groups with the two-tailed Student t test. A p-value < 0.05 was considered statistically significant. Sensitivity and specificity were compared between the qualitative and quantitative studies. The iodine density, lesion-to-muscle ratio, and lesion-to-artery ratio of the iodine density measurement for malignant vertebral tumours were significantly different from the respective values for non-malignancies (all p < 0.05). Using 0.52 as the threshold value for the lesion-to-artery iodine density ratio, one could obtain sensitivity of 85 % and specificity of 100 % for differentiating malignant vertebral tumours from non-malignancies, significantly higher than the qualitative diagnosis. DESCT imaging enables analysis of a number of additional quantitative CT parameters to improve the accuracy for differentiating malignant vertebral tumours from non-malignancies during venous phase.

    2005-10-01

    Artificial intelligence (AI) is a computer based science which aims to simulate human brain faculties using a computational system. A brief history of this new science goes from the creation of the first artificial neuron in 1943 to the first artificial neural network application to genetic algorithms. The potential for a similar technology in medicine has immediately been identified by scientists and researchers. The possibility to store and process all medical knowledge has made this technology very attractive to assist or even surpass clinicians in reaching a diagnosis. Applications of AI in medicine include devices applied to clinical diagnosis in neurology and cardiopulmonary diseases, as well as the use of expert or knowledge-based systems in routine clinical use for diagnosis, therapeutic management and for prognostic evaluation. Biological applications include genome sequencing or DNA gene expression microarrays, modeling gene networks, analysis and clustering of gene expression data, pattern recognition in DNA and proteins, protein structure prediction. In the field of hematology the first devices based on AI have been applied to the routine laboratory data management. New tools concern the differential diagnosis in specific diseases such as anemias, thalassemias and leukemias, based on neural networks trained with data from peripheral blood analysis. A revolution in cancer diagnosis, including the diagnosis of hematological malignancies, has been the introduction of the first microarray based and bioinformatic approach for molecular diagnosis: a systematic approach based on the monitoring of simultaneous expression of thousands of genes using DNA microarray, independently of previous biological knowledge, analysed using AI devices. Using gene profiling, the traditional diagnostic pathways move from clinical to molecular based diagnostic systems.

    2004-01-01

    A survey of the medical directors of multidisciplinary pain clinics and multidisciplinary pain centers listed in the American Pain Society Pain Facilities Directory was conducted to define those pain specialists' beliefs about the role of opioid analgesia in 14 types of chronic nonmalignant pain. Respondents also reported their perceptions of barriers to their prescribing opioids for chronic nonmalignant pain and what they perceived as barriers to opioid prescribing for chronic nonmalignant pain by other, non-pain specialist clinicians in their communities. The respondents are characterized by demographics, disciplines, specialties, and time in practice. The percentage of time that a pharmacist was available in the pain programs also is reported. There is increasing acceptance of opioids for most of the listed types of chronic nonmalignant pain, but the acceptance varies by types of pain syndromes. Opioids were most consistently accepted for sickle cell disease pain and least commonly endorsed for headaches, myofascial pain, and fibromyalgia. Factors that may influence clinicians' perceptions about opioids are discussed.

    Full Text Available Objective. Cytokines and chemokines are widely involved in cancer cell progression and thus represent promising candidate factors for new biomarkers. Methods. Four renal cell cancer (RCC cell lines (Caki-1, 786-O, RCC4, and A498 and a nonmalignant renal cell line (RC-124 were examined with respect to their proliferation. The cytokine and chemokine expression pattern was examined by a DNA array (Human Cytokines & Chemokines RT2 Profiler PCR Array; Qiagen, Hilden, Germany, and expression profiles were compared. Results. Caki-1 and 786-O cells exhibited significantly increased proliferation rates, whereas RCC4 and A498 cells demonstrated attenuated proliferation, compared to nonmalignant RC-124 cells. Expression analysis revealed 52 cytokines and chemokines primarily involved in proliferation and inflammation and differentially expressed not only in malignant and nonmalignant renal cells but also in the four RCC cell lines. Conclusion. This is the first study examining the expression of 84 cytokines and chemokines in four RCC cell lines compared to that in a nonmalignant renal cell line. VEGFA, NODAL, and BMP6 correlated with RCC cell line proliferation and, thus, may represent putative clinical biomarkers for RCC progression as well as for RCC diagnosis and prognosis.

    Europe's firs Hemalog D was installed in the Hematology Laboratory of the Franco-Musulman Hospital at Bobigny, just outside Paris, in March 1975. The authors' experience with the apparatus since that date has enabled them to analyze the significance of "alarms", "high peroxidase", "large unstained cells", "remainder" and "low rate" in patients with and without hematologic disorders. On the basis of these results it has been possible to define the fate of the various blood cells in the Hemalog D, the role of the apparatus in the ivestigation of hematologic disorders and the type of "cooperation" between the hematologist and the Hemalog D.

This study tests the following hypotheses: (1 there is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective; and (2 the main problem associated with the safety of such treatment – assessment of the risk of addiction – has been neglected. Methods: Scientometric analysis of the articles representing clinical research in this area was performed to assess (1 the quality of presented evidence (type of study; and (2 the duration of the treatment phase. The sufficiency of representation of addiction was assessed by counting the number of articles that represent (1 editorials; (2 articles in the top specialty journals; and (3 articles with titles clearly indicating that the addiction-related safety is involved (topic-in-title articles. Results: Not a single randomized controlled trial with opioid treatment lasting >3 months was found. All studies with a duration of opioid treatment ≥6 months (n = 16 were conducted without a proper control group. Such studies cannot provide the consistent good-quality evidence necessary for a strong clinical recommendation. There were profound differences in the number of addiction articles related specifically to chronic nonmalignant pain patients and to opioid addiction in general. An inadequate number of chronic pain-related publications were observed with all three types of counted articles: editorials, articles in the top specialty journals, and topic-in-title articles. Conclusion: There is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective. The above identified signs indicating neglect of addiction associated with the

    2016-11-01

    Existing literature shows mixed conclusions regarding the impact of ABO incompatibility on outcomes after hematopoietic stem cell transplantation. Because the future for umbilical cord blood (UCB) expansion technologies is bright, we assessed whether this typically overlooked graft characteristic impacted various outcomes after UCB transplantation (UCBT) for nonmalignant disorders (NMDs). A prospectively maintained institutional blood and marrow transplant program database was queried for all patients undergoing first UCBT for NMDs. UCB and recipient ABO compatibility was considered as matched, major mismatched, minor mismatched, or bidirectional mismatched. The impact of ABO incompatibility was assessed on overall survival, graft failure, acute and chronic graft-versus-host disease (GVHD), time to neutrophil and platelet recovery, day 0 to day 100 RBC transfusion burden, and donor hematopoietic chimerism. Through December 2014, 270 patients have undergone first UCBT for various NMDs. In both univariable and multivariable analyses, ABO compatibility status did not appear to impact any outcomes assessed, although a trend toward increased grades III to IV acute GVHD was seen in recipients of major mismatched units. When considering UCBT for treatment of NMDs, ABO compatibility between the donor unit and intended recipient does not appear to be an important consideration in the UCB unit choice.

  13. Effectiveness of Massage Therapy for Chronic, Non-Malignant Pain: A Review

    Directory of Open Access Journals (Sweden)

    Jennie C. I. Tsao

    2007-01-01

    Full Text Available Previous reviews of massage therapy for chronic, non-malignant pain have focused on discrete pain conditions. This article aims to provide a broad overview of the literature on the effectiveness of massage for a variety of chronic, non-malignant pain complaints to identify gaps in the research and to inform future clinical trials. Computerized databases were searched for relevant studies including prior reviews and primary trials of massage therapy for chronic, non-malignant pain. Existing research provides fairly robust support for the analgesic effects of massage for non-specific low back pain, but only moderate support for such effects on shoulder pain and headache pain. There is only modest, preliminary support for massage in the treatment of fibromyalgia, mixed chronic pain conditions, neck pain and carpal tunnel syndrome. Thus, research to date provides varying levels of evidence for the benefits of massage therapy for different chronic pain conditions. Future studies should employ rigorous study designs and include follow-up assessments for additional quantification of the longer-term effects of massage on chronic pain.

    Fluorescence-guided diagnosis of tumor tissue is in many cases insufficient, because false positive results interfere with the outcome. Improvement through observation of cell metabolism might offer the solution, but needs a detailed understanding of the origin of autofluorescence. With respect to this, spectrally resolved multiphoton fluorescence lifetime imaging was investigated to analyze cell metabolism in metabolic phenotypes of malignant and nonmalignant oral mucosa cells. The time-resolved fluorescence characteristics of NADH were measured in cells of different origins. The fluorescence lifetime of bound and free NADH was calculated from biexponential fitting of the fluorescence intensity decay within different spectral regions. The mean lifetime was increased from nonmalignant oral mucosa cells to different squamous carcinoma cells, where the most aggressive cells showed the longest lifetime. In correlation with reports in the literature, the total amount of NADH seemed to be less for the carcinoma cells and the ratio of free/bound NADH was decreased from nonmalignant to squamous carcinoma cells. Moreover for squamous carcinoma cells a high concentration of bound NADH was found in cytoplasmic organelles (mainly mitochondria). This all together indicates that oxidative phosphorylation and a high redox potential play an important role in the energy metabolism of these cells.

    Central venous catheters (CVC), used for the management of children with hemato-oncological disorders, are burdened by a significant incidence of mechanical, infective, or thrombotic complications. These complications favor an increasing risk in prolongation of hospitalization, extra costs of care, and sometimes severe life-threatening events. No guidelines for the management of CVC-related occlusion and CVC-related thrombosis are available for children. To this aim, members of the coagulation defects working group and the supportive therapy working group of the Italian Association of Pediatric Hematology and Oncology (AIEOP) reviewed the pediatric and adult literature to propose the first recommendations for the management of CVC-related occlusion and CVC-related thrombosis in children with hemato-oncological disorders.

    Objective To explore the treatment and mechanism of platelet transfusion refractoriness in pediatric hema-tological disorders.Methods Retrospective analyses were performed from 4 children diagnosed with platelet transfusion refractoriness between 2013 and 2014 in Children's Hospital of Soochow University. Clinical manifestation, laboratory tests, and the effect of plasma exchange were evaluated on pediatric platelet refractoriness.Results Two males and two females with age ranged from 2 years to 11 years and 9 months met the criteria of platelet refractoriness. Three cases were diagnosed as AML-M5 (M5), and one case was diagnosed as severe aplastic anemia (SAA). Platelet refractoriness occurred in one case of M5 after induction chemotherapy, and two cases in the stage of hematopoietic stem cell transplantation (HSCT). The SAA patient showed platelet refractoriness on her admission. The screening for HLA antibodies with the method of Immune Luminex beads streaming technology (Luminex) revealed that HLA-I antibody reaction were positive in three patients. All four patients showed a good response to the treatment of plasma exchange.Conclusions HLA-I class antibodies are closely associated with platelet refracto-riness, the plasma exchange treatment is effective and safe for platelet refractoriness in children.%目的 探讨儿童血液肿瘤患者血小板无效输注的分子学机制及治疗.方法回顾性分析2013年至2014年收治的4例血小板无效输注患儿的临床特征及实验室检查资料,评估血浆置换对儿童血小板无效输注的疗效.结果 4例患儿中男2例、女2例,年龄2岁~11岁9个月,其中3例为急性单核细胞白血病(M5),1例为重型再生障碍性贫血(SAA).1例M5患儿首次化疗后、2例M5患儿造血干细胞移植后发生血小板无效输注,1例SAA患儿入院时即表现为血小板无效输注.免疫磁珠流式液相芯片技术(Luminex)检测,3例患儿HLA-I类抗体阳性,1例患者HLA-I类阴性.

    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.

    Full Text Available Zygomycosis are invasive mould infections, rarely diagnosed in hematologic patients. Most of the cases published are in patients with prolonged neutropenia, along with other risk factors such as the use of prior broad-spectrum antibiotics (including new antifungal agents, such as voriconazole, diabetes mellitus (with or without ketoacidosis, malnutrition, iron overload (with or without the use of deferoxamine. These infections have poor prognosis due to the involvement of vital anatomic structures and late diagnosis. Until recent years, the treatment was based on high doses of amphotericin B plus surgical debridement. Here we present two patients with hematologic diseases (one with leukemia, the second with aplastic anemia with an impaired immune system and the diagnosis of zygomycosis. The survival of one of them was mainly due to early diagnosis and surgical debridement; unfortunately the second was misdiagnosed as an extensive ecchymosis due to thrombocytopenia and died with CNS involvement.

    2014-09-01

    Full Text Available Background: Exposure of biological subjects to electromagnetic fields with a high frequency is associated with temperature elevation. In our recent studies, we reported that non-invasive radiofrequency (RF treatment at 13.56 MHz with the field ranging from 1 KeV to 20 KeV/m2 inhibits tumor progression in animals with abdominal tumor xenografts and enhances the anticancer effect of chemotherapy. The RF treatment was followed by temperature elevation in tumors to approximately 46 °C during 10 min of exposure. In contrast, the temperature of normal tissues remained within a normal range at approximately 37 °C. Whether all biological effects of RF treatment are limited to its hyperthermic property remains unclear. Here, we compared how RF and hyperthermia (HT treatments change the proliferation rate, oxygen consumption and autophagy in malignant and nonmalignant cells. Methods: In the current study, cancer and nonmalignant cells of pancreatic origin were exposed to the RF field or to conventional HT at 46 °C, which was chosen based on our previous in vivo studies of the tumor-specific RF-induced hyperthermia. Results: Only RF treatment caused declines in cancer cell viability and proliferation. RF treatment also affected mitochondrial function in cancer cells more than HT treatment did and, unlike HT treatment, was followed by the elevation of autophagosomes in the cytoplasm of cancer cells. Importantly, the effects of RF treatment were negligible in nonmalignant cells. Conclusion: The obtained data indicate that the effects of RF treatment are specific to cancer cells and are not limited to its hyperthermic property.

    The establishment of an optimal noninvasive method for diagnosing invasive aspergillosis (IA) is needed to improve the management of this life-threatening infection in patients with hematological disorders, and a number of noninvasive tests for IA that target different fungal components, including galactomannan, (1→3)-β-d-glucan (BDG), and Aspergillus DNA, have been developed. In this study, we prospectively evaluated the diagnostic potential of three noninvasive tests for IA that were used in a weekly screening strategy: the double-sandwich enzyme-linked immunosorbent assay (ELISA) for galactomannan (Platelia Aspergillus), a real-time PCR assay for Aspergillus DNA (GeniQ-Asper), and an assay for BDG (β-glucan Wako). We analyzed 149 consecutive treatment episodes in 96 patients with hematological disorders who were at high risk for IA and diagnosed 9 proven IA cases, 2 probable IA cases, and 13 possible invasive fugal infections. In a receiver-operating characteristic (ROC) analysis, the area under the ROC curve was greatest for ELISA, using two consecutive positive results (0.97; P = 0.036 for ELISA versus PCR, P = 0.055 for ELISA versus BDG). Based on the ROC curve, the cutoff for the ELISA could be reduced to an optical density index (O.D.I.) of 0.6. With the use of this cutoff for ELISA and cutoffs for PCR and BDG that give a comparable level of specificity, the sensitivity/specificity/positive predictive value/negative predictive value of the ELISA and the PCR and BDG tests were 1.00/0.93/0.55/1.00, 0.55/0.93/0.40/0.96, and 0.55/0.93/0.40/0.96, respectively. In conclusion, among these weekly screening tests for IA, the double-sandwich ELISA test was the most sensitive at predicting the diagnosis of IA in high-risk patients with hematological disorders, using a reduced cutoff of 0.6 O.D.I.

    The purpose of this paper was to examine published qualitative studies that explored the beliefs, values, and behaviors of patients with nonmalignant chronic pain during their interactions with the healthcare system. The findings were used as "cultural cues" to create patient-centered care. A literature review of primary qualitative studies that focused on beliefs, values, or behaviors of patients with chronic nonmalignant pain in the formal healthcare setting was conducted. CINAHL, Medline, Pubmed, PsychInfo, Sociology Abstracts, Cochrane Library Database, Proquest Dissertation and Thesis, and EmBase served as the database for the research. The findings from the studies fell into two categories: beliefs and expectations about appropriate treatment and the behaviors patients may exhibit if they perceive they are not receiving appropriate treatment. Qualitative findings showed that the beliefs, values, and behaviors of patients with nonmalignant chronic pain exhibited during their interactions with the healthcare system created a set of "cultural cues" for providers.

    Evidence indicates sorghum may be protective against colon cancer; however, the mechanisms are unknown. Estrogen is believed to protect against colon cancer development by inducing apoptosis in damaged nonmalignant colonocytes. Three sorghum extracts (white, red, and black) were screened for estrogenic activity using cell models expressing estrogen receptor α (ER-α; MCF-7 breast cancer cells) and β [ER-β; nonmalignant young adult mouse colonocytes (YAMC)]. Black and white sorghum extracts had significant estrogenic activity mediated through both estrogen receptors at 1-5 and 5-10 μg/mL, respectively; but red sorghum did not. Activation of ER-β in YAMC reduced cell growth via induction of apoptosis. Only the black and red sorghums contained 3-deoxyanthocyanins; however, these compounds were non-estrogenic. Flavones with estrogenic properties, luteolin (0.41-2.12 mg/g) and apigenin (1.1-1.4 mg/g), and their O-methyl derivatives (0.70-0.95 mg/g) were detected in white and black sorghums, but not in the red sorghum. On the other hand, naringenin, a flavanone known to interfere with transcriptional activities of estrogen, was only detected in the red sorghum extract (as its 7-O-glycoside) at relatively high concentration (11.8 mg/g). Sorghum flavonoid composition has important implications on possible modes of chemoprotection by sorghum against colon carcinogenesis.

    2007-06-01

    The objective was to develop an integrated review of quantitative and qualitative research regarding the influence of patients' beliefs and attitudes toward pain medication prescribed for the treatment of nonmalignant chronic pain on use of the pain medication. Studies involving patients at least 18 years old with nonmalignant chronic pain were included. Studies of patients with acquired immune deficiency syndrome, cancer, and acute pain were excluded. Medline, CINAHL, PsychInfo, and Cochrane databases from 1985 to 2005 were searched. Reference lists were screened for relevant articles. Abstracts were screened for compliance with the study criteria, and the articles were obtained for those that met criteria. By using a systematic process, each article was subjected to repeated review and data abstracted to the collection sheets. Evidence tables were created to assist with data review. High levels of concern positively correlate with nonadherence, preconceived ideas about when the drug should start working can cause the patient to discontinue it before it begins to work, and patients may perceive that if medication is taken on a regular basis to control pain it may not be effective in the future if the pain increases. Research also showed that if patients perceived the benefits of taking the pain medication to be high, they were willing to risk the side effects.

    Treosulfan (treo) is an alkylating agent with a low acute toxicity profile that is increasingly used in hematopoietic stem cell transplantation, predominantly in non-malignant diseases. Treosulfan is usually combined with additional agents, but there is scant evidence to allow comparison between different conditioning protocols using treosulfan. We present the experience of three pediatric transplantation centers in Israel using different treosulfan-based conditioning regimens. Data were collected retrospectively on 44 children who underwent 45 hematopoietic stem cell transplantations using treosulfan in combination with either fludarabine (flu) and thiotepa (tt) (n = 20), cyclophosphamide (cy) (n = 6) or fludarabine alone (n = 19). Overall survival (OS) was 70.5%. Disease free survival (DFS) was 54.6%. There was no statistically significant difference between treatment groups in either OS or DFS. Overall survival in patients younger than one year was higher (88.2%). There were significantly more patients with 100% donor chimerism transplanted with flu/treo/tt compared with flu/treo or treo/cy (94.7% compared to 66.7% and 16.7%, respectively). Further prospective studies are required to determine the optimal treosulfan-based preparative regimen for children with non-malignant diseases.

    2013-06-01

    Full Text Available Vitamin D is a steroid hormone with a broad range of biological effects ranging from the classical role as a mediator of calcium and phosphate balance to cellular differentiation and immune modulation. These effects impact normal and dysfunctional hematopoietic and immune function, which may allow an avenue for improved treatment and support of patients suffering from hematologic disorders. In this review, we will summarize the role of vitamin D in normal hematopoiesis, discuss ways in which vitamin D may improve outcomes, and discuss a potential role of vitamin D for treating hematologic disorders and modulating the immune system to improve the outcome of allogeneic stem cell transplant.

In the presence of molecule oxygen, the light illumination of photosensitizer can lead to a series of photochemical reactions and consequently generate a variety of cytotoxic species.The nature, location and quantity of PDT-induced cytotoxic species and the sensitivity of the target cells determine the outcome of a PDT treatment.Since the first government approval of photosensitizer Photofrin was granted, for the treatment of bladder cancer in Canada in 1993,1 the utilization of PDT in the treatment of malignant and non-malignant diseases has increased significantly due to the improvement in photosensitizers and light applicators. Several similar photosensitizers have been developed and utilization in China since the 1980s.2

    2010-01-01

    This paper reviews the literature on associations between dry wood dust exposure and non-malignant respiratory diseases. Criteria for inclusion are epidemiological studies in English language journals with an internal or external control group describing relationships between dry wood dust exposure and respiratory diseases or symptoms. Papers took into consideration smoking and when dealing with lung function age. A total of 37 papers forms the basis of this review. The results support an association between dry wood dust exposure and asthma, asthma symptoms, coughing, bronchitis, and acute and chronic impairment of lung function. In addition, an association between wood dust exposure and rhino-conjunctivitis is seen across the studies. Apart from plicatic acid in western red cedar wood, no causal agent has consistently been disclosed. Type 1 allergy is not suspected to be a major cause of wood dust induced asthma.

    Background Arsenic from drinking water has been associated with malignant and nonmalignant respiratory illnesses. The association with nonmalignant respiratory illnesses has not been well established because the assessments of respiratory symptoms may be influenced by recall bias or interviewer bias because participants had visible skin lesions. Objectives We examined the relationship of the serum level of Clara cell protein CC16—a novel biomarker for respiratory illnesses—with well As, total urinary As, and urinary As methylation indices. Methods We conducted a cross-sectional study in nonsmoking individuals (n = 241) selected from a large cohort with a wide range of As exposure (0.1–761 μg/L) from drinking water in Bangladesh. Total urinary As, urinary As metabolites, and serum CC16 were measured in urine and serum samples collected at baseline of the parent cohort study. Results We observed an inverse association between urinary As and serum CC16 among persons with skin lesions (β = −0.13, p = 0.01). We also observed a positive association between secondary methylation index in urinary As and CC16 levels (β = 0.12, p = 0.05) in the overall study population; the association was stronger among people without skin lesions (β = 0.18, p = 0.04), indicating that increased methylation capability may be protective against As-induced respiratory damage. In a subsample of study participants undergoing spirometric measures (n = 31), we observed inverse associations between urinary As and predictive FEV1 (forced expiratory volume measured in 1 sec) (r = −0.37; FEV1/forced vital capacity ratio and primary methylation index (r = −0.42, p = 0.01). Conclusions The findings suggest that serum CC16 may be a useful biomarker of epithelial lung damage in individuals with arsenical skin lesions. Also, we observed the deleterious respiratory effects of As exposure at concentrations lower than reported in earlier studies. PMID:18288317

  3. Cytogenetically unrelated clones in hematological neoplasms.

    We have reviewed literature data on 6,306 cases of hematological neoplasia--acute and chronic lymphatic and myeloid leukemias (CML excepted), myelodysplastic and chronic lymphoproliferative and myeloproliferative disorders, and malignant lymphomas--with the goal of quantitatively ascertaining how often cytogenetically unrelated clones occur in these diseases. Unexpectedly wide variations were found: in ANLL, unrelated clones were present in 1.1% of the 2,506 known cases with chromosome abnormalities characterized with banding technique; in the various myelodysplastic (MDS) and chronic myeloproliferative (CMD) disorders (total number of cases 1,299) the frequency was 4.3% and in lymphatic malignancies 1.3% (total case number 2,501). In the latter group the proportions varied between 0.4% and 0.6% in ALL and malignant lymphoma (ML) to as much as 6.2% in CLD and 7.3% in CLL. Some karyotypic abnormalities were encountered more often than would be expected from their general frequency in the various diseases. This discrepancy was particularly evident in MDS and CMD, where 5q- was found in slightly less and +8 in somewhat more than half of the 56 cases. Furthermore, these two aberrations were found as the only changes in the two coexisting clones in one-fourth of the material. Although if viewed in isolation these data would undoubtedly be best explained by assuming a multicellular origin of the neoplasm, it is entirely possible that what are cytogenetically perceived as unrelated clones could be subclones with some invisible aberration in common. If so, this interpretation indicates that changes like +8 and 5q-, both of which are common rearrangements in bone marrow neoplasms, are actually secondary changes that develop during tumor progression.

  6. Thermal effects on bluegill hematology. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Murray, S.A.

    1983-03-01

    Temperature effects on hematological responses of adult bluegill were examined for constant vs fluctuating temperature regimes, for ambient vs high temperature, and for intake vs discharge at an operating power plant. Multivariate statistical methods were used to determine temperature effects. An increased erythrocyte fragility was associated with fluctuating temperature regimes as well as with the suboptimal temperature regime. Thrombocytosis with a concomitant leukopenia was observed for the higher fluctuating and higher acclimating temperatures. Reduced erythrocytic sedimentation rates were observed for the higher temperatures. Although hematology may vary depending on fish size, good hematological indicators of potential thermal stress were associated with red blood cell morphology, particularly cell size and/or shape. However, in situ hematological responses of bluegill at an operating power plant were apparently not affected by the associated thermal gradients.

  10. Targeting hedgehog in hematologic malignancy.

    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.

    1972-01-01

    Study of the effects of hypoxia, activity, and G forces on human hematopoiesis in an attempt to elucidate these phenomena more precisely. Eight subjects were exposed to an atmosphere of 100% O2 at 258 mm Hg for 30 days, and thereafter immediately exposed to transverse G forces, simulating the Gemini flights' reentry profile. All subjects displayed a significant continuous decline in red cell mass during the exposure period, as measured by the carbon monoxide-dilution method. The Cr51 method also indicated a decline in red blood corpuscle mass. The decrease in red cell mass was due to suppression of erythropoiesis and to hemolysis. After exposure to hyperoxia, all subjects exhibited elevated plasma hemoglobin levels, decreased reticulocyte counts, and decreased red cell survivals. CO production rates and urine erythropoietin levels were unchanged. Two hours after termination of exposure to hyperoxia, all subjects exhibited increased reticulocyte counts which were sustained for longer than two weeks. The progressive decrease in red cell mass was promptly arrested on return to ground level atmospheres. Within 116 days after exposure to hyperoxia, the hematologic parameters of all eight subjects had returned to control levels.

  12. Oncolytic Virotherapy for Hematological Malignancies

    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.

    The pervasive disease of chronic pain is a common challenge for the clinical rehabilitation professional. Concurrent with physical and emotional symptoms, pain-related cognitive impairment has been reported. Although opioid analgesics are frequently prescribed, concern exists that opioids possess adverse cognitive effects of their own. To review the neuropsychological and neuroanatomical sequelae of chronic non-malignant pain and opioid therapy, to clarify roles and benefits of neuropsychological assessment in a chronic pain population, and to provide recommendations for clinical practice and future research. This non-systematic review sought to provide a comprehensive synthesis of relevant neurobiology, neuroimaging, neuropsychological, and rehabilitation research literatures. We included citations from seminal and current texts as well as relevant original and review articles from 1980-2012 in PubMed and PubMedCentral online research databases. To date, evidence from opioid studies suggests only mild deficits in specific cognitive domains (e.g., memory, attention/concentration) and only under specific conditions (e.g., dose escalations). Additionally, neuroimaging and neuropsychological evidence suggests that pain itself results in cognitive sequelae. Methodological improvements in future research will allow for better delineation of the contributing effects of pain and opioids, with an overall goal of improving evidence-based clinical treatment recommendations.

    Hematopoietic cell transplantation (HCT) is effective in the treatment of patients with nonmalignant diseases and for many is the only known cure. Conventional myeloablative regimens have been associated with unacceptably high early transplant-related mortality (TRM) particularly in patients with co-morbid conditions. This prospective multicenter trial was designed to determine the safety and engraftment efficacy of treosulfan-based conditioning in patients with nonmalignant diseases. Thirty-one patients received HLA-matched related (n=4) or unrelated (n=27) grafts following conditioning with treosulfan (total dose: 42 g/m2), fludarabine (total dose: 150 mg/m2), ± thymoglobulin (6 mg/kg; n=22). Graft-versus-host disease (GVHD) prophylaxis consisted of tacrolimus and methotrexate. All patients engrafted. Day-100 TRM was 0%. With a median follow-up of 2 years, the 2-year survival was 90%. Three patients died of GVHD, recurrent hemophagocytic lymphohistiocytosis, and a surgical complication, respectively. The cumulative incidences of grades II–IV and III–IV acute GVHD at day 100 and chronic GVHD at 2 years were 62%, 10% and 21%, respectively. Patients who received thymoglobulin had a significantly lower incidence of grade III-IV acute GVHD (0% versus 33%; P = 0.005). These results indicate that the combination of treosulfan, fludarabine, and thymoglobulin is effective at establishing donor engraftment with low toxicity and improved survival in patients with nonmalignant diseases, and support the need for future disease-specific clinical trials.

    Chronic pain is a frequent cause of suffering and disability that seriously affects patients' quality of life and imposes a staggering socioeconomic toll on society. Little is known about the impact of patient-physician disagreement (discordance) regarding the assessment of chronic pain on patients' quality of life in primary care settings. This study evaluates the role of discordance and other potentially modifiable factors that affect the quality of life and functional status of chronic pain patients. We evaluated 436 patient-physician encounters at 12 academic medical centers in the United States. We surveyed chronic nonmalignant pain patients to understand their pain perceptions. We concurrently surveyed their physicians about their perceptions of their patient's pain in primary care settings. More than 50% of physicians disagreed with their patient's pain. Thirty-nine percent of primary care physicians underestimated their patient's pain. In the multivariate analysis, this discordance was associated with poor physical functioning and worse bodily pain (P < 0.018 and P < 0.001 respectively). Patients with chronic, nonmalignant pain have reductions in physical function and bodily pain domains of the SF-36 compared to age-matched populations. Depression and obesity represented other associations. Patients with chronic nonmalignant pain have poor physical functioning and worse bodily pain. Discordance, obesity, and depression are other modifiable factors. Prospective studies are needed to design interventions. However, a multifaceted approach appears to represent the best opportunity to reduce the pain and suffering of this challenging population.

    Full Text Available Context: Laparoscopic splenectomy (LS is considered the standard approach for the treatment of children with nonmalignant hematological diseases due to the advances in the minimal invasive surgery over the conventional splenectomy (CS. Different techniques are involved in the operation to secure the hilum. Aim: The use of (Ligasure™ is a safe, effective, less time consuming and with less complications rate. Materials and Methods: Sixty children (33 with thalassemia, 20 with immune thrombocytopenic purpura [ITP] and seven with spherocytosis were operated during the period from June 2007 to December 2014. These children had undergone LS using (Ligasure™. Three ports were used in small-sized spleens while four ports were used in large spleens. Results: There were 60 children (37 girls and 23 boys with a mean age of 10.2 years had LS using Ligasure™ with mean operative time of 85 min for cases of ITP and 120 min for other cases. There was no mortality. Two cases were converted to CS. Conclusions: Use of Ligasure™ alone was safe, less time consuming with less complications rates.

    Lysyl oxidase (LOX) has been shown to both promote and suppress tumor progression, but its role in prostate cancer is largely unknown. LOX immunoreactivity was scored in prostate tumor epithelium, tumor stroma and in the tumor-adjacent non-malignant prostate epithelium and stroma. LOX scores in tumor and non-malignant prostate tissues were then examined for possible associations with clinical characteristics and survival in a historical cohort of men that were diagnosed with prostate cancer at transurethral resection and followed by watchful waiting. Men with a low LOX score in the non-malignant prostate epithelium had significantly longer cancer specific survival than men with a high score. Furthermore, LOX score in non-malignant prostate epithelium remained prognostic in a multivariable analysis including Gleason score. LOX score in prostate tumor epithelium positively correlated to Gleason score and metastases but was not associated with cancer survival. LOX score in tumor and non-malignant prostate stroma appeared unrelated to these tumor characteristics. In radical prostatectomy specimens, LOX immune-staining corresponded to LOX in-situ hybridization and LOX mRNA levels were found to be similar between tumor and adjacent non-malignant areas, but significantly increased in bone metastases samples. LOX levels both in tumors and in the surrounding tumor-bearing organ are apparently related to prostate cancer aggressiveness.

    2014-07-01

    Full Text Available Background: Hematological disorders may present with a number of non-specific orofacial manifestations that must be diagnosed and referred to specialists for treatment. Since the orofacial manifestations can be the first clinical presentation which indicates the presence of an underlying disease, it is important for dentists to be aware of these manifestations. The present study aims to evaluate the orofacial presentations of some hematological diseases in order to familiarize dentists with these manifestations. Methods: This descriptive cross-sectional study evaluated the oral conditions of patients recently hospitalized with histories of blood dyscrasia and bone marrow transplantation in Shiraz Nemazee Hospital during 2010-2011. From 50 patients, there were 33 (66% males and 17 (34% females. The age of participants ranged from 12-77 years of age. Results: Examined patients had the following manifestations: head and neck region lymphadenopathy (42%, hairy tongue, atrophy of the oral mucosa, ulcers, red and white lesions, Candida albicans infection and gingival lesions that included spontaneous gingival bleeding, gingival hypertrophy and ecchymosis, in addition to diffuse herpetic infections on the buccal mucosa and bony lesions. The most common blood dyscrasia in the study patients was acute myeloid leukemia (AML (48%. Our findings determined that lymphadenopathy (42% was the most common orofacial manifestation of hematological diseases. Conclusion:On occasion, dentists maybe the first medical professional to encounter hematological diseases. Since early detection of these disorders can increase patient survival, it is necessary for dentists to become completely familiar with these oral manifestations.

    Full Text Available Abstract Background The aim of the present study was to determine whether stage of invasiveness of bladder cancer cell lines contributes to alterations in glycan pattern of their cadherins. Results Human non-malignant epithelial cell of ureter HCV29, v-raf transfected HCV29 line (BC3726 and transitional cell cancers of urine bladder Hu456 and T24 were grown in cell culture. Equal amounts of protein from each cell extracts were separated by SDS-PAGE electrophoresis and were blotted on an Immobilon P membrane. Cadherins were immunodetected using anti-pan cadherin mAb and lectin blotting assays were performed, in parallel. N-oligosaccharides were analysed by specific reaction with Galanthus nivalis agglutinin (GNA, Sambucus nigra agglutinin (SNA, Maackia amurensis agglutinin (MAA, Datura stramonium agglutinin (DSA, Aleuria aurantia agglutinin (AAA, Phaseolus vulgaris agglutinin (PHA-L and wheat germ agglutinin (WGA. The cadherin from HCV29 cell line possessed bi- and/or 2,4-branched triantennary complex type glycans, some of which were α2,6-sialylated. The cadherin from BC3726 cell line exhibited exclusively high mannose type glycans. Cadherins from Hu456 and T24 cell lines expressed high mannose type glycans as well as β1,6-branched oligosaccharides with poly-N-acetyllactosamine structures and α2,3-linked sialic acid residues. Additionally, the presence of fucose and α2,6-sialic acid residues on the cadherin from T24 cell line was detected. Conclusions These results indicate that N-glycosylation pattern of cadherin from bladder cancer cell line undergoes modification during carcinogenesis.

    2017-08-01

    Background Analgesics are used in the management of chronic non-malignant pain (CNMP), a condition which is highly prevalent among older adults. CNMP may not only be physically distressing but also complicated by psychosocial and economic factors. An individual's perception and use of analgesics may be influenced by a range of factors such as perceptions of risk or benefits, ability to purchase medication or access to non-pharmacological therapies or specialist care. Objective The aim of this study was to describe the perceptions and experiences of analgesics by ageing and elderly individuals with CNMP and identify factors that influence their use. Setting Telephone interviews with 28 members of Chronic Pain Ireland aged ≥50. Method In-depth semi-structured interviews; audio-recorded, transcribed verbatim, and thematically analysed. Main outcome measure Experiences and perceptions of ageing and elderly individuals with CNMP taking analgesics. Results A combination of factors specific to the patient and arising from outside influences informed perceptions and experiences of analgesics. Pain severity, perceived efficacy of analgesics, occurrence of adverse-effects and concerns about addiction/dependence were identified as internal factors influencing medication use. External factors included views of family members, access to specialised care and the individual's interaction with healthcare professionals (HCPs). Conclusion Individuals with CNMP regard analgesics as an important method for managing pain and are relied upon when other interventions are difficult to access. HCPs in primary care, who are the main point of contact for patients, need to take into account the various factors that may influence analgesic use when consulting with this patient group.

  4. In Vitro Leukoagglutination: A Rare Hematological Cause of Spurious Leukopenia

    Full Text Available Leukopenia secondary to leukocytic agglutination is caused by an ethylene diamine tetra acetic acid (EDTA which may appear in both benign and malignant states. Ethylene diamine tetra acetic acid induced platelets clumping in peripheral blood has been well established, but invitro leukocytic aggregation is very rarest hematological finding. Pseudo-leukopenia resulting from leukoagglutinins has been reported in the cirrhotic state, infections, autoimmune disorders, uremia, in immunosuppressed state or in various malignancies. Though the condition seems to be benign but very important to be detected as these artifactual findings lead to unnecessary investigations and remarkably changed the overall management plan. Here we report the case of a young patient with this rare finding who was admitted to our hospital with progressive labor pains. The analysis of ethylene diaminetetraacetic acid (EDTA, anticoagulated blood was done on automated hematology analyzer reveals leukopenia. The peripheral smear examination revealed multiple aggregates of leukocytes. On repeat sampling in citrate anticoagulant, the complete blood count showed total leukocytic count of 16.5x109/L with absolute neutrophilic count of 11.5x109/L. This is a rare case of spurious leukopenia secondary to in-vitro leukocytic agglutination provoked by EDTA anticoagulant.

    The various blood cell counts of neonates must be interpreted in accordance with high-quality reference intervals based on gestational and postnatal age. Using very large sample sizes, we generated neonatal reference intervals for each element of the complete blood count (CBC). Knowledge of whether a patient has CBC values that are too high (above the upper reference interval) or too low (below the lower reference interval) provides important insights into the specific disorder involved and in many instances suggests a treatment plan.

    2014-02-01

    Great advances have been made in the treatment of hematological malignancies, but achieving a definitive cure remains an elusive goal for the majority of patients. Antigen-specific tumor immunotherapy has the potential to improve clinical outcome in patients with such diseases by eradicating chemotherapy-resistant tumor cell clones without damaging normal tissues. Dendritic cells (DCs) serve as an essential link between the innate and the adaptive immune systems, acting as key controllers of antigen-specific T cell responses. Molecular identification of tumor-specific antigens recognized by T lymphocytes and technical advances in ex vivo generation of human DCs has enabled us to develop DC-based tumor immunotherapies (also called "DC vaccines"). To date, a large number of clinical trials of DC vaccines have been conducted for a variety of tumors, including hematological malignancies. Overall, these trials have demonstrated that DC vaccines have excellent safety profiles, moderate immunological activity, and mild clinical efficacy. To establish a role for DC vaccines in the treatment of hematological malignancies, we need both to define patient populations that can obtain clinical benefit from DC vaccines and to develop combination therapies that augment clinical efficacy of DC vaccines. In this review, I will describe current status of DC-based immunotherapy for hematological malignancies, and discuss future perspectives in this field.

  15. Hematological Side Effects of Atypical Antipsychotic Drugs

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Atypical antipsychotics cause less frequently extrapyramidal system symptoms, neuroleptic malignant syndrome and hyperprolactinemia than typical antipsychotics. However hematological side effects such as leukopenia and neutropenia could occur during treatment with atypical antipsychotics. These side effects could lead to life threatening situations and the mortality rate due to drug related agranulocytosis is about 5-10%. There are several hypothesis describing the mechanisms underlying drug induced leukopenia and/or neutropenia such as direct toxic effects of these drugs upon the bone marrow or myeloid precursors, immunologic destruction of the granulocytes or supression of the granulopoiesis. Clozapine is the antipsychotic agent which has been most commonly associated with agranulocytosis. A nitrenium ion which is formed by the bioactivation of clozapine is thought to have an important role in the pathophysiogy of this adverse effect. Aside from clozapine, there are several case reports reporting an association between olanzapine, quetiapine, risperidone, ziprasidone, aripiprazole and leukopenia. We did not find any study or case report presenting amisulpride or sulpride related hematological side effects in our literature search. Patients who had hematological side effects during their previous antipsychotic drug treatments and who had lower baseline blood leukocyte counts, have higher risk to develop leukopenia or neutropenia during their current antipsychotic treatment. Once leukopenia and neutropenia develops, drugs thought to be responsible for this side effect should be discontinued or dosages should be lowered. In some cases iniatition of lithium or G-CSF (granulocyte colony-stimulating factor therapy may be helpful in normalizing blood cell counts. Clinicans should avoid any combination of drugs known to cause hematological side effects. Besides during antipsychotic treatment, infection symptoms such as fever, cough, sore throat or

    1992-11-01

    Automated hematology analyzers are used in all large hospitals and most commercial laboratories, as well as in most smaller hospitals and laboratories, to perform complete blood counts (including white blood cell, red blood cell, and platelet counts; hemoglobin concentration; and RBC indices) and white blood cell differential counts. Our objectives in this study are to provide user guidance for selecting, purchasing, and using an automated hematology analyzer, as well as to present an overview of the technology used in an automated five-part differential unit. Specifications for additional automated units are available in ECRI's Clinical Laboratory Product Comparison System. We evaluated the Miles Technicon H.2 unit and rated it Acceptable. The information in this Single Product Evaluation is also useful for purchasing other models; our criteria will guide users in assessing components, and our findings and discussions on some aspects of automated hematology testing are common to many available systems. We caution readers not to base purchasing decisions on our rating of the Miles unit alone, but on a thorough understanding of the issues surrounding automated hematology analyzers, which can be gained only by reading this report in its entirety. The willingness of manufacturers to cooperate in our studies and the knowledge they gain through participating lead to the development of better products. Readers should refer to the Guidance Section, "Selecting and Purchasing an Automated Hematology Analyzer," where we discuss factors such as standardization, training, human factors, manufacturer support, patient population, and special features that the laboratory must consider before obtaining any automated unit; we also provide an in-depth review of cost issues, including life-cycle cost analyses, acquisition methods and costs of hardware and supplies, and we describe the Hemacost and Hemexmpt cost worksheets for use with our PresValu and PSV Manager CAHDModel software

  17. The Need for Hematology Nurse Education in Low- and Middle-Income Countries: A Community Case Study in Tanzania.

    2017-01-01

    Hematology-related diseases, such as anemia, malaria, sickle cell disease (SCD), and blood cancers, have differing rates of survival between high-income and low- and middle-income countries (LMICs). Nurses in LMICs have an unmet need for specialty training and education to address hematology and hemato-oncology disorders. A gap in the literature exists about hematology nurse education and clinical service demands in LMICs. This community case study documents a collaborative hematology and basic hemato-oncology education program to sustainably strengthen nurse capacity at a national referral hospital and university in Tanzania. The goal of the intervention was to provide culturally competent nurse training in pediatric and adult hematology. A certified pediatric nurse practitioner with hematology and oncology experience provided culturally competent training and staff development to nurses over two weeks to meet this goal. Prior to development of a training schedule, nurses confidentially identified five of their top learning needs. Main hematology and basic oncology educational needs identified by nurses were the management of anemia, safe handling of cytotoxic agents, and treatment of SCD. The format of the education varied from bedside teaching to formal presentations to one-on-one individual discussions. Overall, nurses expressed satisfaction with the education and verbalized appreciation for teaching and training activities tailored to meet their needs. Specialized training in hematology and hemato-oncology has the potential to increase nurses' confidence, respect, and participation in interprofessional team decision-making. Lessons learned from the impact of collaborative nurse education and partnership in Tanzania can be generalized to other LMICs. This community case study highlights the importance of specialty nurse education, interprofessional development, and global partnerships needed to improve patient outcomes.

  18. A mega-ethnography of eleven qualitative evidence syntheses exploring the experience of living with chronic non-malignant pain.

    Each year over five million people develop chronic non-malignant pain and can experience healthcare as an adversarial struggle. The aims of this study were: (1) to bring together qualitative evidence syntheses that explore patients' experience of living with chronic non-malignant pain and develop conceptual understanding of what it is like to live with chronic non-malignant pain for improved healthcare; (2) to undertake the first mega-ethnography of qualitative evidence syntheses using the methods of meta-ethnography. We used the seven stages of meta-ethnography refined for large studies. The innovation of mega-ethnography is to use conceptual findings from qualitative evidence syntheses as primary data. We searched 7 bibliographic databases from inception until February 2016 to identify qualitative evidence syntheses that explored patients' experience of living with chronic non-malignant pain. We identified 82 potential studies from 556 titles, screened 34 full text articles and included 11 qualitative evidence syntheses synthesising a total of 187 qualitative studies reporting more than 5000 international participants living with chronic pain. We abstracted concepts into 7 conceptual categories: (1) my life is impoverished and confined; (2) struggling against my body to be me; (3) the quest for the diagnostic 'holy grail'; (4) lost personal credibility; (5) trying to keep up appearances; (6) need to be treated with dignity; and (7) deciding to end the quest for the grail is not easy. Each conceptual category was supported by at least 7 of the 11 qualitative evidence syntheses. This is the first mega-ethnography, or synthesis of qualitative evidence syntheses using the methods of meta-ethnography. Findings help us to understand that the decision to end the quest for a diagnosis can leave patients feeling vulnerable and this may contribute to the adversarial nature of the clinical encounter. This knowledge demonstrates that treating a patient with a sense that they

    Exposure to asbestos is associated with the development of mesothelioma. In addition to asbestos, other fibers have been identified as risk factors for malignant and non-malignant diseases of the lungs. Among these, fluoro-edenite (FE) was found in patients from Biancavilla (Sicily, Italy) with pleural and lung disease, suggesting its role for tumor expansion. In this context, the identification of early biomarkers useful for the diagnosis of cancer is mandatory. Fibulin-3 represents an important marker for the diagnosis of mesothelioma. However, it remains to be determined whether it is directly associated with exposure to asbestos-like fibers. In the present study, peripheral blood levels of fibulin-3 from 40 asbestos-exposed workers were compared with those detected in 27 street cleaners from Biancavilla. Intriguingly, the results showed that fibulin-3 levels were higher in the group of street cleaners compared with those of the asbestos-exposed workers, suggesting that these workers used the personal protective equipment according to the current regulations. These data suggest that subjects exposed to FE should be monitored for the risk of mesothelioma. FE and volcanic particulates are probably contained within dust inhaled by street cleaners from Biancavilla during their work activities. Based on these criteria, in this study, such fibers were used to treat mesothelial cells (MeT5A) in order to verify whether fibulin-3 levels are affected by these treatments. The results showed that only treatment with FE was associated with fibulin-3 overexpression at both the transcript and protein levels. It was previously demonstrated that mesothelial cells exhibited low levels of p27 following treatment with FE. Notably, p27 downregulation is associated with stathmin upregulation in cancer, conferring an aggressive phenotype of tumor cells. This observation prompted us to perform a computational evaluation demonstrating the activation of stathmin in lung cancer in

    This is an updated version of the original Cochrane review published in Issue 1, 2010, on 'Benzodiazepines for the relief of breathlessness in advanced malignant and non-malignant diseases in adults'. Breathlessness is one of the most common symptoms experienced in the advanced stages of malignant and non-malignant disease. Benzodiazepines are widely used for the relief of breathlessness in advanced diseases and are regularly recommended in the literature. At the time of the previously published Cochrane review, there was no evidence for a beneficial effect of benzodiazepines for the relief of breathlessness in people with advanced cancer and chronic obstructive pulmonary disease (COPD). The primary objective of this review was to determine the efficacy of benzodiazepines for the relief of breathlessness in people with advanced disease. Secondary objectives were to determine the efficacy of different benzodiazepines, different doses of benzodiazepines, different routes of application, adverse effects of benzodiazepines, and the efficacy in different disease groups. This is an update of a review published in 2010. We searched 14 electronic databases up to September 2009 for the original review. We checked the reference lists of all relevant studies, key textbooks, reviews, and websites. For the update, we searched CENTRAL, MEDLINE, and EMBASE and registers of clinical trials for further ongoing or unpublished studies, up to August 2016. We contacted study investigators and experts in the field of palliative care asking for further studies, unpublished data, or study details when necessary. We included randomised controlled trials (RCTs) and controlled clinical trials (CCTs) assessing the effect of benzodiazepines compared with placebo or active control in relieving breathlessness in people with advanced stages of cancer, chronic obstructive pulmonary disease (COPD), chronic heart failure (CHF), motor neurone disease (MND), and idiopathic pulmonary fibrosis (IPF

    Cough associated with cancer or nonmalignant chronic disease is common and distressing. Levodropropizine, a peripherally acting drug, has been used as an alternative antitussive to opioids. The authors aimed to determine the efficacy and safety of levodropropizine in relieving cough associated with cancer or nonmalignant chronic disease. The authors searched five databases and hand searched relevant journals to identify randomized and nonrandomized controlled trials assessing the antitussive effect of levodropropizine for cough associated with cancer, chronic obstructive pulmonary disease (COPD), interstitial lung disease, or chronic heart failure. Study quality was assessed using a modified version of the Centre for Reviews and Dissemination criteria. The search yielded 58 references. Six were checked in more detail, and four studies were included. Two were randomized controlled trials (RCTs) testing levodropropizine against dihydrocodeine and moguisteine, and two were nonrandomized placebo-controlled studies, all with important limitations and high risk of bias. Levodropropizine was significantly more effective than placebo in reducing cough frequency and severity, and equally effective as dihydrocodeine or moguisteine. It was generally well tolerated. The authors conclude that the evidence for the antitussive efficacy of levodropropizine in these patients is scarce, and is further limited by the methodological weaknesses of the primary studies. Further well-designed research is needed to support its use.

    An increasing number of children with non-malignant diseases can be cured by allogeneic haematopoietic stem cell transplantation (HSCT). Treosulfan (L-treitol-1,4-bis-methanesulfonate) is being used more frequently for conditioning, owing to its' lower toxicity profile compared with conventional myeloablative regimens. A retrospective analysis was performed of children registered in the EBMT database, who received treosulfan before HSCT between January 2005 and 2010, to identify possible dose-related toxicity and determine the incidence of engraftment, treatment-related mortality and overall survival (OS). Results from 316 transplants from 11 different countries are presented. Ninety-five (30%) were under 1 year of age at the time of transplant. OS was 83% and event-free survival was 76%; 3-year OS and event-free survival of infants below 1 year were 79% and 73%, respectively. No association was found with age at transplant, dose of treosulfan given, other agents used in combination with treosulfan, donor type, stem cell source, or second or subsequent transplant. In this report of the largest number of children to date receiving treosulfan for non-malignant diseases, treosulfan is shown to be a safe and effective agent even for those under 1 year of age at the time of transplant. Further prospective studies are needed using precisely defined protocols with pharmacokinetic monitoring and detailed chimerism analysis. In addition, long-term studies will be vital to determine long-term effects, for example, on fertility in comparison with other regimens.

    The complement pathway is a cascade of proteases that is involved in immune surveillance and innate immunity, as well as adaptive immunity. Dysfunction of the complement cascade may be mediated by aberrations in the pathways of activation, complement regulatory proteins, or complement deficiencies, and has been linked to a number of hematologic disorders, including paroxysmal noctural hemoglobinuria (PNH), hereditary angioedema (HAE), and atypical hemolytic-uremic syndrome (aHUS). Here, current laboratory tests for disorders of the complement pathway are reviewed, and their utility and limitations in hematologic disorders and systemic diseases are discussed. Current therapeutic advances targeting the complement pathway in treatment of complement-mediated hematologic disorders are also reviewed.

    Full Text Available Introduction: There are few studies that investigated whether Down syndrome (DS interferes with references values for complete blood counts (CBC test in children with the syndrome. Objective: This study aimed to analyze the results of CBC performed in children with DS. Patients and methods: Data from CBC of DS children were included; at the time of examination they were aged between 2 and 10 years and had no clinical signs and/or symptoms of infectious disease. The hematological parameters analyzed were: total number of erythrocytes (RBC, hemoglobin (Hb concentration, hematological indices, platelet count, and total number of leucocytes. Additionally, we compared the collected parameters according to gender and age of the children studied. Results: A total of 203 CBC (100 girls and 103 boys were evaluated. In general, no significant differences were observed in studied parameters between the values found in samples of DS children and the values described in the literature as a reference for children in this age group. No difference in the prevalence of anemia was observed in relation to gender (p = 0.33, 14/103 (13.6% boys, and 11/100 (11% girls had anemia. However, the Hb and hematological indices values found in boys was significantly lower than in girls (p < 0.001. Conclusion: This investigation is the first one in Brazil to present and analyze the CBC results of DS children, reporting that their hematological indices are within the expected range for children without DS. Additionally, it was found that 12.3% of them had anemia.

    Little is known about the prevalence of hematologic abnormalities in adults with severe anorexia nervosa. We report the first major analysis of hematologic dysfunction in such patients. We retrospectively analyzed the charts of 53 men and women with severe anorexia nervosa, admitted between October 2008 and December 2010 for medical stabilization to our center, which has a national referral base. Patients were predominantly female (89 %), with a median age of 28 years (range 17-65), and were hospitalized for a median duration of 15 days (I.Q.R. 9-29). Nadir body mass index during hospitalization was markedly low at 12.4 kg/m(2) (range 8.4-15.7), and the mean discharge BMI was 13.8 kg/m(2) (range 10.2-16.8). 83 % of patients were anemic (hematocrit  400 k/μL) during their hospitalization. Eighty-nine percent of patients had resolved their neutropenia by discharge. Marked hematologic deficiencies are often present in patients with severe anorexia nervosa, generally attributed to starvation-mediated gelatinous marrow transformation which resolves with proper nutritional rehabilitation. Improved provider awareness of this association may reduce unnecessary testing and costly treatment interventions.

    2014-01-01

    Helicobacter pylori (H. pylori) is the most common infection in humans, with a marked disparity between developed and developing countries. Although H. pylori infections are asymptomatic in most infected individuals, they are intimately related to malignant gastric conditions such as gastric cancer and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and to benign diseases such as gastritis and duodenal and gastric peptic ulcers. Since it was learned that bacteria could colonize the gastric mucosa, there have been reports in the medical literature of over 50 extragastric manifestations involving a variety medical areas of specialization. These areas include cardiology, dermatology, endocrinology, gynecology and obstetrics, hematology, pneumology, odontology, ophthalmology, otorhinolaryngology and pediatrics, and they encompass conditions with a range of clear evidence between the H. pylori infection and development of the disease. This literature review covers extragastric manifestations of H. pylori infection in the hematology field. It focuses on conditions that are included in international consensus and management guides for H. pylori infection, specifically iron deficiency, vitamin B12 (cobalamin) deficiency, immune thrombocytopenia, and MALT lymphoma. In addition, there is discussion of other conditions that are not included in international consensus and management guides on H. pylori, including auto-immune neutropenia, antiphospholipid syndrome, plasma cell dyscrasias, and other hematologic diseases.

    2015-01-01

    Full Text Available In recent years the role of tumor microenvironment in the progression of hematological malignancies has been widely recognized. Recent studies have focused on how cancer cells communicate within the microenvironment. Among several factors (cytokines, growth factors, and ECM molecules, a key role has been attributed to extracellular vesicles (EV, released from different cell types. EV (microvesicles and exosomes may affect stroma remodeling, host cell functions, and tumor angiogenesis by inducing gene expression modulation in target cells, thus promoting cancer progression and metastasis. Microvesicles and exosomes can be recovered from the blood and other body fluids of cancer patients and contain and deliver genetic and proteomic contents that reflect the cell of origin, thus constituting a source of new predictive biomarkers involved in cancer development and serving as possible targets for therapies. Moreover, due to their specific cell-tropism and bioavailability, EV can be considered natural vehicles suitable for drug delivery. Here we will discuss the recent advances in the field of EV as actors in hematological cancer progression, pointing out the role of these vesicles in the tumor-host interplay and in their use as biomarkers for hematological malignancies.

    Increasing clinical productivity expectations at academic medical centers and new faculty effort reporting requirements for NIH-supported investigators challenge the tradition of faculty volunteerism for medical student teaching. To better define the structure, content, and financial support of second year medical school hematology courses nationwide, we mailed a survey to the hematology course directors at 85 of the 125 accredited US medical schools. The 58 course directors who returned the survey represent all regions of the US and both public and private medical schools. Median class size was 150 students (range 40-200), and some courses included a substantial proportion (up to 33%) of other types of students. The median number of hours per course was 33 h (range 8 to 74). Approximately 50% of the total teaching time was devoted to lecture (range 5 to 100%). Web-based teaching was used by 62% of course directors. The median number of faculty responsible for teaching the second year hematology course was 12 (range 1-36). The hematology course directors identified a number of obstacles, including difficulty in recruiting teachers, the lack of well-defined content, and the very modest budget (less than $1,500 for most courses). Only three of the course directors indicated that they received salary support for this role. These findings suggest that a national effort to define learning objectives for the hematology courses and to share teaching materials among medical schools is warranted. Little financial support is provided for the hematology course, and these findings compel the identification of resources to pay faculty for teaching medical student required courses.

    2015-01-01

    Introduction Placental mesenchymal dysplasia is a rare vascular disease associated with intrauterine growth restriction, fetal demise as well as Beckwith–Wiedemann syndrome. Some neonates present hematologic abnormalities possibly related to consumptive coagulopathy and hemolytic anemia in the placental circulation. Case report We present a case of placental mesenchymal dysplasia in a fetus with intrauterine growth restriction and cerebellar hemorrhagic injury diagnosed in the 20th week of pregnancy. During 26th week, our patient had an intrauterine fetal demise in the context of gestational hypertension. We have detailed the ultrasound findings that made us suspect the presence of hematologic disorders during 20th week. Discussion We believe that the cerebellar hematoma could be the consequence of thrombocytopenia accompanied by anemia. If hemorrhagic damage during fetal life is found, above all associates with an anomalous placental appearance and with intrauterine growth restriction, PMD should be suspected along other etiologies.

    A significant part of the population suffers from non-malignant chronic pain that is not treated by pain specialists. No successful long-term treatment exists. The patients have to deal with their condition in collaboration with health personnel establishing treatment programmes under uncertain circumstances with few guidelines. Thus, there is a strong need for knowledge on how patients with chronic non-malignant pain manage their condition. The aim of the study was to explore how patients with chronic non-malignant pain deal with their condition. Twenty patients with chronic non-malignant pain (aged 26-63 in year 2006) told in an open-ended interview situation, how they lived with and dealt with their condition. The interviews were analysed within a phenomenological meaning condensation framework. For all patients the pain was as an integrated part of their life that required huge efforts to cope with. Typically, the patients experienced loneliness, fear of stigmatization and despair because of their unpredictable condition, and they wanted to come back to a normalized daily life, first and foremost by getting back to paid work. In general, the patients developed individual strategies that were influenced by their local contexts and life situation as well as the pain itself. This may be interpreted in line with Bourdieu's notions of habitus, strategies and social capital.

    Nonmalignant chronic pain (NMCP) is a public health concern. Among primary care appointments, 22% focus on pain management. The American Academy of Pain Medicine guidelines for NMCP recommend combination medication therapy (including analgesics, nonsteroidal anti-inflammatory drugs [NSAIDs], opioids, antidepressants, and anticonvulsants) as a key component to effective treatment for many chronic pain diagnoses. However, there has been little evidence outlining the costs of pain medications in adult patients with NMCP in the United States, an area that necessitates further consideration as the nation moves toward value-based benefit design. To estimate the cost of pain medication attributable to treating adult patients with NMCP in the United States and to analyze the trend of outpatient pain visits. This cross-sectional study used the National Ambulatory Medical Care Survey (NAMCS) data from 2000-2007. The Division of Health Care Statistics, National Center for Health Statistics, and the Centers for Disease Control and Prevention conducted the survey. The study included patients aged ≥18 years with chronic pain diagnoses (identified by the ICD-9-CM codes: primary, secondary, and tertiary). Patients prescribed at least 1 pain medication were included in the cost analysis. Pain-related prescription medications prescribed during ambulatory care visits were retrieved by using NAMCS drug codes/National Drug Code numbers. National pain prescription frequencies (weighted) were obtained from NAMCS data, using the statistical software STATA. We created pain therapy categories (drug classes) for cost analysis based on national pain guidelines. Drug classes used in this analysis were opioids/opioid-like agents, analgesics/NSAIDs, tricyclic antidepressants, selective serotonin reuptake inhibitors, antirheumatics/immunologics, muscle relaxants, topical products, and corticosteroids. We calculated average prices based on the 3 lowest average wholesale prices reported in the

    Background: Hematologic analysis is an important tool in evaluating the general health status of free-ranging manatees and in the diagnosis and monitoring of rehabilitating animals. Objectives: The purpose of this study was to evaluate diagnostically important hematologic analytes in healthy manatees (Trichechus manatus) and to assess variations with respect to location (free ranging vs captive), age class (small calves, large calves, subadults, and adults), and gender. Methods: Blood was collected from 55 free-ranging and 63 captive healthy manatees. Most analytes were measured using a CELL-DYN 3500R; automated reticulocytes were measured with an ADVIA 120. Standard manual methods were used for differential leukocyte counts, reticulocyte and Heinz body counts, and plasma protein and fibrinogen concentrations. Results: Rouleaux, slight polychromasia, stomatocytosis, and low numbers of schistocytes and nucleated RBCs (NRBCs) were seen often in stained blood films. Manual reticulocyte counts were higher than automated reticulocyte counts. Heinz bodies were present in erythrocytes of most manatees. Compared with free-ranging manatees, captive animals had slightly lower MCV, MCH, and eosinophil counts and slightly higher heterophil and NRBC counts, and fibrinogen concentration. Total leukocyte, heterophil, and monocyte counts tended to be lower in adults than in younger animals. Small calves tended to have higher reticulocyte counts and NRBC counts than older animals. Conclusions: Hematologic findings were generally similar between captive and free-ranging manatees. Higher manual reticulocyte counts suggest the ADVIA detects only reticulocytes containing large amounts of RNA. Higher reticulocyte and NRBC counts in young calves probably reflect an increased rate of erythropoiesis compared with older animals. ?? 2009 American Society for Veterinary Clinical Pathology.

  2. Ionizing radiation predisposes non-malignant human mammaryepithelial cells to undergo TGF beta-induced epithelial to mesenchymaltransition

    Transforming growth factor {beta}1 (TGF{beta}) is a tumor suppressor during the initial stage of tumorigenesis, but it can switch to a tumor promoter during neoplastic progression. Ionizing radiation (IR), both a carcinogen and a therapeutic agent, induces TGF{beta}, activation in vivo. We now show that IR sensitizes human mammary epithelial cells (HMEC) to undergo TGF{beta}-mediated epithelial to mesenchymal transition (EMT). Non-malignant HMEC (MCF10A, HMT3522 S1 and 184v) were irradiated with 2 Gy shortly after attachment in monolayer culture, or treated with a low concentration of TGF{beta} (0.4 ng/ml), or double-treated. All double-treated (IR+TGF{beta}) HMEC underwent a morphological shift from cuboidal to spindle-shaped. This phenotype was accompanied by decreased expression of epithelial markers E-cadherin, {beta}-catenin and ZO-1, remodeling of the actin cytoskeleton, and increased expression of mesenchymal markers N-cadherin, fibronectin and vimentin. Furthermore, double-treatment increased cell motility, promoted invasion and disrupted acinar morphogenesis of cells subsequently plated in Matrigel{trademark}. Neither radiation nor TGF{beta} alone elicited EMT, even though IR increased chronic TGF{beta} signaling and activity. Gene expression profiling revealed that double treated cells exhibit a specific 10-gene signature associated with Erk/MAPK signaling. We hypothesized that IR-induced MAPK activation primes non-malignant HMEC to undergo TGF{beta}-mediated EMT. Consistent with this, Erk phosphorylation were transiently induced by irradiation, persisted in irradiated cells treated with TGF{beta}, and treatment with U0126, a Mek inhibitor, blocked the EMT phenotype. Together, these data demonstrate that the interactions between radiation-induced signaling pathways elicit heritable phenotypes that could contribute to neoplastic progression.

A clinical practice guideline was developed following the guidelines of the Methodological Guide of the Ministry of Social Protection to collect evidence and grade recommendations. De novoliterature researchwas performed. With the use of antipsychotics there isriskofreducción in the leukocyte count and the risk of agranulocytosis,the later associated with the use of clozapine, although it is a rare event(0.8%) can be fatal; this effect occurs most frequently in the first twelve weeks of treatment and the risk is maintained aroundthe first year of it. The recommendations were considered strongin all hematologic related monitoring.A blood count should be taken at the start of pharmacological treatment. If the patient is started on clozapine one shouldbe taken weekly during the first three months, monthly until completing one year and every six months thereafter. If there is a decrease in white blood cell count the patient should be monitored regularly, stopping if is a less than 3,500 cells/mm(3) and consider referral if is less than 2,000 cells/mm(3).

    Full Text Available Hepatitis C is a significant public health problem in Egypt where the highest prevalence (14.7% of hepatitis C virus (HCV exists. HCV prevalence is even higher among clinical populations and groups at risk of exposure to infection. Chronic HCV infection is associated with several hematological complications that may necessitate bone marrow (BM examination. The aim of this study is to estimate HCV prevalence among patients referred for BM examination and to explore hematological and BM findings among HCV positive patients. One hundred adult patients referred for BM examination were included in the study and screened for HCV antibodies. Patients’ clinical, hematological, and BM findings were recorded. The seroprevalence of HCV among patients referred for BM examination was 42%. The most common indication for BM examination among HCV positive patients was peripheral cytopenias (88.1%. The most common cytopenia detected was thrombocytopenia (85.7%. The most common diagnosis among HCV positive patients was hypersplenism (52.4% followed by B-lymphoproliferative disorders (19% and then immune thrombocytopenic purpura (11.9%. In conclusion, HCV prevalence among patients referred for BM examination is higher than that estimated in the general population. Patients with unexplained peripheral cytopenias should be tested for HCV.

    Peripherally inserted central catheters (PICC) have the advantage of limiting the risk of accidents during installation and are easy to remove. Its use in oncology remains debated because of possible infectious complications. We analyzed 52 PICC in patients with hematological tumor from Nice Hospital. An installation failure was noted in 5.8% of cases. After a follow-up of 15 months, the complication rate was 26.9%, mainly mechanical complications: obstruction (13.5%) or accidental removal (9.6%). The organic complications such as infection or thrombophlebitis represented 3.8%. The median duration was 26 days [2-291]. The longest duration was associated with PICC for chemotherapy (median: 58 days). Frequent blood samples (above: 2 week) were associated with lower duration (median: 23 days). In conclusion, PICC represent a simple and effective alternative to intra-venous central devices in onco-hematology. However, physicians have to focus on short-course treatment.

  10. Application of biomarkers in population studies for respiratory non-malignant diseases.

    1995-07-26

    Though the use of biomarkers has been mainly suggested for cancer studies, the possibility of its use in non malignant disease is considered. Markers of internal dose, markers of biologically effective dose and markers of early biologically effect have been typically used in basic research and, more recently, in epidemiology to characterize genotoxic carcinogenic agents. These markers (e.g. adducts to DNA or proteins) may be used mainly in the presence of chronic exposure to toxic agents (e.g. benzene or benzopyrene), additional markers such as carboxyhemoglobin, expired air to measure various VOC and heavy metals in biological fluids are also considered in the paper. Since airway obstructive disease (asthma, chronic bronchitis, emphysema) are the main disorders influenced by environmental factors (including air pollution), markers of individual susceptibility, such as atopy increased responsiveness of airways, initial level of lung function, must be considered for a more precise evaluation of the relationship between environmental exposure and health effects. Currently, the application of the determination of markers of exposure in non malignant disorders is very limited. In fact, the relationships between acute adverse respiratory effects and the exposure to air pollutants appears difficult since markers for common air pollutants are not available, and their detection appears difficult in acute conditions. Characterization of long term exposure may be performed in organ fluids (blood, urine, saliva) however it is important to recognize that concentration at that level may not reflect that observed in the target organ (e.g. lung).

    The most common hematological malignancy in pregnant patients is Hodgkin's lymphoma, but other diseases such as chronic and acute leukemia or non Hodgkin's lymphoma have also been reported. In the last decade, new drugs have changed the prognostic of acute promyelocytic leukemia, chronic myeloid leukemia and non Hodgkin's lymphoma. Herein we present updated information on drugs and treatments, new developments, mechanism of action, clinical application, experience on treatment outcomes, adverse effects and teratogenesis, with the objective of orienting hematologists, oncologists and pediatricians. The medical team should offer the most efficient treatment available in order to achieve cure or remission of the disease, and also inform on possible risks for the mother and the fetus, as well as those derived from the delay in treatment application.

    Full Text Available Hematologic malignancies represent the fourth most frequently diagnosed cancer in economically developed countries. In hematologic malignancies normal hematopoiesis is interrupted by uncontrolled growth of a genetically altered stem or progenitor cell (HSPC that maintains its ability of self-renewal. Cyclin-dependent kinases (CDKs not only regulate the mammalian cell cycle, but also influence other vital cellular processes, such as stem cell renewal, differentiation, transcription, epigenetic regulation, apoptosis, and DNA repair. Chromosomal translocations, amplification, overexpression and altered CDK activities have been described in different types of human cancer, which have made them attractive targets for pharmacological inhibition. Mouse models deficient for one or more CDKs have significantly contributed to our current understanding of the physiological functions of CDKs, as well as their roles in human cancer. The present review focuses on selected cell cycle kinases with recent emerging key functions in hematopoiesis and in hematopoietic malignancies, such as CDK6 and its role in MLL-rearranged leukemia and acute lymphocytic leukemia, CDK1 and its regulator WEE-1 in acute myeloid leukemia, and cyclin C/CDK8/CDK19 complexes in T-cell acute lymphocytic leukemia. The knowledge gained from gene knockout experiments in mice of these kinases is also summarized. An overview of compounds targeting these kinases, which are currently in clinical development in various solid tumors and hematopoietic malignances, is presented. These include the CDK4/CDK6 inhibitors (palbociclib, LEE011, LY2835219, pan-CDK inhibitors that target CDK1 (dinaciclib, flavopiridol, AT7519, TG02, P276-00, terampeprocol and RGB 286638 as well as the WEE-1 kinase inhibitor, MK-1775.

    Full Text Available Abstract Vorinostat (Zolinza®, a histone deacetylase inhibitor, was approved by the US Food and Drug Administration in October 2006 for the treatment of cutaneous manifestations in patients with cutaneous T-cell lymphoma who have progressive, persistent or recurrent disease on or following two systemic therapies. This review summarizes evidence on the use of vorinostat in solid and hematologic malignancies and collated tolerability data from the vorinostat clinical trial program. Pooled vorinostat clinical trial data from 498 patients with solid or hematologic malignancies show that vorinostat was well tolerated as monotherapy or combination therapy. The most commonly reported drug-related adverse events (AEs associated with monotherapy (n = 341 were fatigue (61.9%, nausea (55.7%, diarrhea (49.3%, anorexia (48.1%, and vomiting (32.8%, and Grade 3/4 drug-related AEs included fatigue (12.0%, thrombocytopenia (10.6%, dehydration (7.3%, and decreased platelet count (5.3%. The most common drug-related AEs observed with vorinostat in combination therapy (n = 157, most of whom received vorinostat 400 mg qd for 14 days were nausea (48.4%, diarrhea (40.8%, fatigue (34.4%, vomiting (31.2%, and anorexia (20.4%, with the majority of AEs being Grade 2 or less. In Phase I trials, combinations with vorinostat were generally well tolerated and preliminary evidence of anticancer activity as monotherapy or in combination with other systemic therapies has been observed across a range of malignancies. Ongoing and planned studies will further evaluate the potential of vorinostat in combination therapy, including combinations with radiation, in patients with diverse malignancy types, including non-small-cell lung cancer, glioblastoma multiforme, multiple myeloma, and myelodysplastic syndrome.

    Background and purpose: In HIV infected patients, MRI cannot reliably differentiate between central nervous system (CNS) lymphoma and non-malignant CNS lesions, particularly cerebral toxoplasmosis (CTOX). This study prospectively investigates the utility of FDG PET-CT and magnetic resonance spectroscopy (MRS) in discriminating CNS lymphoma from non-malignant CNS lesions in HIV infected patients, and assesses the ability of FDG PET-CT to guide the use of early brain biopsy. Methods: 10 HIV patients with neurological symptoms and contrast enhancing lesions on MRI were commenced on anti-toxoplasmosis therapy before undergoing FDG PET-CT and MRS. Brain biopsies were sought in those with FDG PET-CT suggestive of CNS lymphoma, and in those with a negative FDG PET-CT scan who failed to respond to therapy. Final diagnosis was based on histology or treatment response. Results: Two patients were confirmed to have CNS lymphoma and FDG PET-CT was consistent with this diagnosis in both. Six patients had cerebral toxoplasmosis in all of whom FDG PET-CT was consistent with non-malignant disease. One patient had progressive multifocal leukoencephalopathy (PML), FDG PET-CT was equivocal. One patient had a haemorrhagic brain metastasis and FDG PET-CT wrongly suggested non-malignant disease. MRS was performed successfully in eight subjects: three results were suggestive of CNS lymphoma (one true positive, two false positive), four suggested CTOX (two false negative, two true negative), one scan was equivocal. Conclusion: FDG PET-CT correctly identified all cases of CNS lymphoma and CTOX, supporting its use in this situation. MRS was unhelpful in our cohort.

    Highlights: • We assumed that some of erythropoietin adverse effects may be mediated by telomerase activity. • EPO administration increased telomerase activity, cells proliferation and migration. • The inhibition of telomerase modestly repressed the proliferative effect of erythropoietin. • Telomere shortening caused by long term inhibition of the enzyme totally abolished that effect. • This effect was mediated via the Lyn–AKT axis and not by the canonical JAK2–STAT pathway. - Abstract: Treatment with erythropoietin (EPO) in several cancers is associated with decreased survival due to cancer progression. Due to the major importance of telomerase in cancer biology we hypothesized that some of these effects may be mediated through EPO effect on telomerase. For this aim we explored the possible effects of EPO on telomerase regulation, cell migration and chemosensitivity in non-erythroid malignant and non-malignant cells. Cell proliferation, telomerase activity (TA) and cell migration increased in response to EPO. EPO had no effect on cancer cells sensitivity to cisplatinum and on the cell cycle status. The inhibition of telomerase modestly repressed the proliferative effect of EPO. Telomere shortening caused by long term inhibition of the enzyme abolished the effect of EPO, suggesting that EPO effects on cancer cells are related to telomere dynamics. TA was correlated with the levels of Epo-R. The increase in TA was mediated post-translationally through the Lyn-Src and not the canonical JAK2 pathway.

    2010-01-01

    This paper reviews associations in literature between exposure to wood dust from fresh wood and non-malignant respiratory diseases. Criteria for inclusion are epidemiological studies in English language journals with an internal or external control group describing relationships between wood dust exposure and respiratory diseases or symptoms. The papers took into account smoking, and when dealing with lung function took age into consideration. A total of 25 papers concerning exposure to fresh wood and mixed wood formed the basis of this review. The results support an association between fresh wood dust exposure and asthma, asthma symptoms, coughing, bronchitis, and acute and chronic impairment of lung function. In addition, an association between fresh wood dust exposure and rhino-conjunctivitis was seen across studies. Apart from plicatic acid in western red cedar wood, no causal agent was consistently disclosed. Type 1 allergy is not suspected of being a major cause of wood dust induced asthma. Concurrent exposure to microorganisms and terpenes probably add to the inherent risk of wood dust exposure in the fresh wood industry.

    Heat shock proteins (HSPs), which are important for a number of different intracellular functions, are occasionally found on the surface of cells. The function of heat shock protein on the cell surface is not understood, although it has been shown to be greater in some tumor cells and some virally infected cells. Surface expression of both glycoprotein 96 (gp96) and Hsp70 occurs on tumor cells, and this expression correlates with natural killer cell killing of the cells. We examined the surface expression of gp96 and Hsp70 on human breast cell lines MCF7, MCF10A, AU565, and HS578, and in primary human mammary epithelial cells by immunofluorescence microscopy and flow cytometry. The nonmalignant cell lines HS578, MCF10A, and HMEC showed no surface expression of gp96, whereas malignant cell lines MCF7 and AU565 were positive for gp96 surface expression. All of the breast cell lines examined showed Hsp70 surface expression. These results also confirm previous studies, demonstrating that Hsp70 is on the plasma membrane of tumor cell lines. Given the involvement of heat shock proteins, gp96 and Hsp70, in innate and adaptive immunity, these observations may be important in the immune response to tumor cells.

    Full Text Available Introduction. Hyperhemolysis is characterized by a life-threatening hemolytic transfusion reaction, with hemoglobin (Hb and hematocrit (Hct dropping markedly lower than before transfusion. This phenomenon, commonly described in sickle cell disease, is a rare occurrence in patients without hemoglobinopathies. Case Report. A 55-year-old male presented to the hospital after a motorcycle crash and received 10 units of cross-matched blood for active bleeding. The patient was blood group O, with a negative antibody screen. Ten days later, he represented complaining of dyspnea and was found to have a hematocrit of 12%. The direct antiglobulin test was positive for anti-immunoglobin G and complement. Indirect antiglobulin test was positive for anti-Jka alloantibodies. The presence of Jka antigen was revealed in one unit of previously transfused blood; patient’s RBCs were negative for the Jka antigen. Laboratory data demonstrated findings consistent with DHTR, as well as reticulopenia and elevated ferritin levels. He continued to show signs of active hemolysis, requiring a total of 4 subsequent units of pRBCs. Each transfusion precipitated a drop in Hb and Hct to levels lower than before transfusion; once transfusions were held, the patient slowly recovered. Discussion. Hyperhemolysis in the setting of a DHTR can occur in patients without hematologic disease.

    Full Text Available Most invasive fungal infections occur in patients with hematologic malignancies and the prevalence has increased steadily in recent years due to intensive cytotoxic chemotherapies, stem cell transplantation, myeloablative radiation therapy, and the use of corticosteroids, cyclosporine or new immunosuppressive agents. Although Candida is the main fungal agent involved in invasive fungal infection (IFI, an increasing number of infections are caused by molds, mostly Aspergillus spp, but in the last 20 years other emerging fungal pathogens such as Zygomycetes causing mucormycosis have appeared with higher mortality rates. The rhinocerebral and pulmonary forms of mucormycosis together with disseminated disease have the highest mortality (78-100%. Zygomycetes characteristically invade blood vessels, causing thrombosis and infarction with necrosis and scarring. Rapid diagnosis of zygomycosis is vital for management and therapy since these infections progress rapidly. Treatment should combine early aggressive surgical excision of the necrotic lesions, restoration of immune function if possible, and amphotericin B at a dose of 1-1.5 mg/kg or a new antifungal such as posaconazole.

    to present main clinical and hematologic features of pediatric leukemias treated at Hematooncologic department of Pediatric Clinic in Sarajevo during last 7 years. In retrospective study we followed up children with leukemia aged 0-15 who were treated during period of 01.01.1997-31.12.2003. at Hematooncologic department on Pediatric Clinic in Sarajevo. A total number of patient with leukemia was 130 of them 112 (83.2%) had acute lymphoblastic leukemia (ALL), 16 (12.3%) of them had acute myeloid leukemia (AML) and 2 (1.5%) patients had chronic myeloid leukemia (CML). There were 84 (64.6%) boys and 46 (35.4%) girls. Median age of newly diagnosed patients was 6 years and 4 months. Dominant clinical signs were: high temperature-72.9%, fatigue and paleness-74.8% and bone pain-87.9%. Most of the children had leucocitosis (51.5%), anemia (56.1%) and trombocitopenia (57.5%). Most frequent signs at the beginning of the illness are general symptoms like fatigue, unclear febrile state and accented bone pains. Those united signs with complete blood picture finding should be enough reason for suspicion under possible leukemia.

    Connective Tissue (CT) is a ubiquitous component of all major tissues and structures of the body (50% of all body protein is CT), including that of the blood, vascular, muscle, tendon, ligament, fascia, bone, joint, IVD's (intervertebral discs) and skin. Because of its ubiquitous nature, CT is an often overlooked component of any essential nutritional program that may address the structure, and/or function of these tissues. The central role of CT in the health of a virtually all cells, tissues, organs, and organ systems, is discussed. General nutritional CT support strategies, as well as specific CT support strategies that focus on blood, vascular, structural system (eg, muscles, tendons, ligaments, fascia, bone, and joints), integument (skin) and inflammatory and immune mediation will be discussed here and will deal with connective tissue dynamics and dysfunction. An overview of the current scientific understanding and possible options for naturally enhancing the structure and function of CT through the application of these concepts will be discussed in this article, with specific attention on the vascular and hematological systems.

    2013-09-01

    Full Text Available Acute intermittent porphyria is the most common acute porphyria caused by a decrease in hepatic porphobilinogen deaminase activity, resulting in an accumulation of delta-aminolevulinic acid and porphobilinogen. This disease shows nonspecific signs and symptoms that can be confused with other diseases, thereby making the diagnosis difficult. We report a case of acute intermittent porphyria, reviewing clinical and laboratory aspects, highlighting the hematological and biochemical parameters during and after the crisis. A female patient, aged 28 years, suffered two crises, both presenting gastrointestinal disorders. The second presented neuropsychiatric symptoms. The analysis of hematological and biochemical parameters during the second crisis showed anemia, leukocytosis, hyponatremia, mild hypokalemia, uremia and elevated C-reactive protein. The initial treatment included glucose infusion, a diet rich in carbohydrates and interruption of porphyrinogenic drugs. Subsequently, treatment was maintained with oral contraceptive use. According to the observed data, signs and symptoms of gastrointestinal, neurological and psychiatric disorders, associated with laboratory results presented in this paper can be applied to screen acute porphyria, contributing to early diagnosis.

    Successful treatment of Cushing syndrome causes transient or permanent adrenal insufficiency deriving from endogenous hypercortisolism-induced hypothalamus-pituitary-adrenal-axis suppression. We analyzed pre-treatment factors potentially affecting the duration of adrenal insufficiency. We conducted a retrospective analysis on patients successfully treated for Cushing disease (15 patients) who underwent transsphenoidal surgery, and nonmalignant primary adrenal Cushing syndrome (31 patients) who underwent unilateral adrenalectomy, divided into patients with overt primary adrenal Cushing syndrome (14 patients) and subclinical primary adrenal Cushing syndrome (17 patients). Epidemiological data, medical history, and hormonal parameters depending on the etiology of hypercortisolism were collected and compared to the duration of adrenal insufficiency. The median duration of follow-up after surgery for Cushing disease and primary adrenal Cushing syndrome was 70 and 48 months, respectively. In the Cushing disease group, the median duration of adrenal insufficiency after transsphenoidal surgery was 15 months: younger age at diagnosis and longer duration of signs and symptoms of hypercortisolism before diagnosis and surgery were associated with longer duration of adrenal insufficiency. The median duration of adrenal insufficiency was 6 months for subclinical primary adrenal Cushing syndrome and 18.5 months for overt primary adrenal Cushing syndrome. The biochemical severity of hypercortisolism, the grade of hypothalamus-pituitary-adrenal-axis suppression, and treatment with ketoconazole before surgery accounted for longer duration of adrenal insufficiency. In patients with Cushing disease, younger age and delayed diagnosis and treatment predict longer need for glucocorticoid replacement therapy after successful transsphenoidal surgery. In patients with primary adrenal Cushing syndrome, the severity of hypercortisolism plays a primary role in influencing the duration of

    A case-control study of hematological malignancies was conducted among Chernobyl liquidators (accident recovery workers) from Belarus, Russia and Baltic countries in order to assess the effect of low-to-medium dose protracted radiation exposures on the relative risk of these diseases. The study was nested within cohorts of liquidators who had worked in 1986–87 around the Chernobyl plant. 117 cases (69 leukemia, 34 non-Hodgkin Lymphoma (NHL) and 14 other malignancies of lymphoid and hematopoietic tissue) and 481 matched controls were included in the study. Individual dose to the bone marrow and uncertainties were estimated for each subject. The main analyses were restricted to 70 cases (40 leukemia, 20 NHL and 10 other) and their 287 matched controls with reliable information on work in the Chernobyl area. Most subjects received very low doses (median 13 mGy). For all diagnoses combined, a significantly elevated OR was seen at doses of 200 mGy and above. The Excess Relative Risk (ERR) per 100 mGy was 0.60 (90% confidence interval (CI): −0.02, 2.35). The corresponding estimate for leukemia excluding chronic lymphoid leukemia (CLL) was 0.50 (90%CI −0.38, 5.7). It is slightly higher than, but statistically compatible with, those estimated from a-bomb survivors and recent low dose-rate studies. Although sensitivity analyses showed generally similar results, we cannot rule out the possibility that biases and uncertainties could have led to over or underestimation of the risk in this study.

    Pediatric hematology and oncology (PHO) is a rapidly expandingfield. It has been our goal to meet the needs and increasing demands for comprehensive medical care of children suffering from chronic blood diseases and malignancies. In the past decade we have been able expand and optimize the PHO services throughout Iran, in general and in respect to their prevalence and clinical importance, by trained pediatric hematologist-oncologists, pediatric surgeons and improved para clinical facilities. Major beta-thalassemics receive blood transfusion and chelation therapy according to the current standards mostly at regional blood banks centers. To curb major beta-thalassemia a premarital screening program has been enacted and abortion has been legitimized if major thalassemia is diagnosed by CVS. Hemophiliacs are supervised and treated as indicated by Iranian Hemophilia Comprehensive Care Centers (IHCCC). Screening for transfusion related complications and transmitted viral diseases (HBV, HCV and HIV) in both cohorts are carried out in regular intervals and necessary management will be then carried out as indicated at respective specialized units. Childhood malignancies are treated according to protocols adopted from accredited institutions in the USA and Europe, with almost comparable results. BMT is available for selected patients with beta-thalassemia or malignancies. By going to public we have been able to rise general awareness about chronic blood diseases and childhood malignancies and have initiated establishment of parents groups and formation of NGOs to support these children and their families. Foundation of Iranian Society of Pediatric Hamatology and Oncology (ISPHO) in the year 2000 has been another step forward to consolidate and coordinate the available manpower and facilities. By evaluation of the country's main problems and shortcomings and conduction of collaborative studies and operation planning one will succeed to get the expected feedback and

    A case-control study of malignant and non-malignant respiratory disease among employees of the Owens-Corning Fiberglas Corporation's Newark, Ohio plant was undertaken. The aim was to determine the extent to which exposures to substances in the Newark plant environment, to non-workplace factors, or to a combination may play a part in the risk of mortality from respiratory disease among workers in this plant. A historical environmental reconstruction of the plant was undertaken to characterise the exposure profile for workers in this plant from its beginnings in 1934 to the end of 1987. The exposure profile provided estimates of cumulative exposure to respirable fibres, fine fibres, asbestos, talc, formaldehyde, silica, and asphalt fumes. Employment histories from Owens-Corning Fiberglas provided information on employment characteristics (duration of employment, year of hire, age at first hire) and an interview survey obtained information on demographic characteristics (birthdate, race, education, marital state, parent's ethnic background, and place of birth), lifetime residence, occupational and smoking histories, hobbies, and personal and family medical history. Matched, unadjusted odds ratios (ORs) were used to assess the association between lung cancer or non-malignant respiratory disease and the cumulative exposure history, demographic characteristics, and employment variables. Only the smoking variables and employment characteristics (year of hire and age at first hire) were statistically significant for lung cancer. For non-malignant respiratory disease, only the smoking variables were statistically significant in the univariate analysis. Of the variables entered into a conditional logistic regression model for lung cancer, only smoking (smoked for six months or more v never smoked: OR = 26.17, 95% confidence interval (95% CI) 3.316-206.5) and age at first hire (35 and over v less than 35: OR = 0.244, 95% CI 0.083-0.717) were statistically significant.

    Although many inflammatory cytokines are prognostic in sepsis, the utility of cytokines in evaluating disease severity in pediatric hematology/oncology patients with septic shock was rarely studied. On the other hand, a single particular cytokine is far from ideal in guiding therapeutic intervention, but combination of multiple biomarkers improves the accuracy. In this prospective observational study, 111 episodes of septic shock in pediatric hematology/oncology patients were enrolled from 2006 through 2012. Blood samples were taken for inflammatory cytokine measurement by cytometric bead array (CBA) technology at the initial onset of septic shock. Interleukin (IL)-6 and IL-10 were significantly elevated in majority of patients, while tumor necrosis factor (TNF)-α and interferon (IFN)-γ were markedly increased in patients with high pediatric index of mortality 2 (PIM2) score and non-survivors. All the four cytokines paralleled the PIM2 score and differentially correlated with hemodynamic disorder and fatal outcomes. The pediatric multiplex cytokine score (PMCS), which integrated the four cytokines into one score system, was related to hemodynamic disorder and mortality as well, but showed more powerful prediction ability than each of the four cytokines. PMCS was an independent predictive factor for fatal outcome, presenting similar discriminative power with PIM2, with accuracy of 0.83 (95% CI, 0.71-0.94). In conclusion, this study develops a cytokine scoring system based on CBA technique, which performs well in disease severity and fatality prediction in pediatric hematology/oncology patients with septic shock.

  14. Influence of Genetic Variants in EGF and Other Genes on Hematological Traits in Korean Populations by a Genome-Wide Approach

    Full Text Available Hematological traits are important health indicators and are used as diagnostic clinical parameters for human disorders. Recently, genome-wide association studies (GWAS identified many genetic loci associated with hematological traits in diverse ethnic groups. However, additional GWAS are necessary to elucidate the breadth of genetic variation and the underlying genetic architecture represented by hematological metrics. To identify additional genetic loci influencing hematological traits (such as hematocrit, hemoglobin concentration, white blood cell count, red blood cell count, and platelet count, we conducted GWAS and meta-analyses on data from 12,509 Korean individuals grouped into population-based cohorts. Of interest is EGF, a factor plays a role in the proliferation and differentiation of hematopoietic progenitor cells. We identified a novel EGF variant, which associated with platelet count in our study (Pcombined=2.44×10-15. Our study also replicated 16 genetic associations related to five hematological traits with genome-wide significance (P<5×10-8 that were previously established in other ethnic groups. Of these, variants influencing platelet count are distributed across several genes and have pleiotropic effects in coronary artery disease and dyslipidemia. Our findings may aid in elucidating molecular mechanisms underlying not only hematopoiesis but also inflammatory and cardiovascular diseases.

    Toxoplasmosis can be a severe opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS), and also among solid organ transplant and allogeneic hematopoietic stem cell transplant (HSCT) patients. Patients with low-grade or chronic hematologic malignancies are treated with increasing immunosuppressive regimens and, therefore, represent an emerging population at risk for opportunistic diseases. We report here two cases of disseminated toxoplasmosis occurring in non-allografted hematologic patients with chronic lymphoproliferations. A review of 44 cases from the literature reveals that toxoplasmosis occurs increasingly in indolent B cell lymphoproliferative disorders. Aggressive lymphoproliferations, adenosine analogs, autologous HSCT, and the absence of chemoprophylaxis are the main risk factors for opportunistic toxoplasmosis. The central nervous system is the main organ involved. Fever is only present in half of all cases. Latent Toxoplasma cysts reactivation (LTCR) is the most common, but primary infection occurs in about 20% of cases. Global mortality is over 50%.

    Therapy-related myelodysplastic syndrome/acute myeloid leukemia (t-MDS/AML) is a feared long-term complication of pediatric cancer. Few osteosarcoma patients develop t-MDS/AML, but the frequency of hematological abnormalities after therapy is unknown. We reviewed biochemistry from osteosarcoma patients up to 3 years posttreatment. All children diagnosed with osteosarcoma at our department from 2006 to 2012 without relapse 1 month posttherapy were included (n=14). Serial blood counts posttherapy were analyzed. The median increase of mean corpuscular volume (MCV) from baseline was 8 fL 6 months posttherapy and remained >5 throughout follow-up. All posttreatment levels of MCV were above 90 fL in 5 patients. Six months posttherapy, the median difference for platelets, white blood count, and absolute neutrophil count had decreased from baseline. They remained under baseline throughout follow-up. Hemoglobin remained stable. Ferritin level was associated with increased MCV. MDS with monosomy 7 was diagnosed in 1 patient. Hypoplastic refractory cytopenia was found in another patient showing spontaneous normalization of hematologic values. More than a third of patients treated for osteosarcoma developed hematological abnormalities mimicking early MDS, but only 1 developed t-MDS/AML. Close hematological monitoring of patients recovering from osteosarcoma is essential and it is worth noting that hematological abnormalities are frequent and may be transitory.

    BACKGROUND: There is a paucity of data regarding hematological abnormalities in adults with Down\\'s syndrome (DS). AIMS: We aimed to characterize hematological abnormalities in adult patients with DS and determine their long-term significance. METHODS: We retrospectively studied a cohort of nine DS patients referred to the adult hematology service in our institution between May 2001 and April 2008. Data collected were: full blood count (FBC), comorbidities, investigations performed, duration of follow-up and outcome to most recent follow-up. RESULTS: Median follow-up was 26 months (9-71). Of the nine patients, two had myelodysplastic syndrome (MDS) at presentation. Of these, one progressed, with increasing marrow failure, and requiring support with transfusions and gCSF. The remaining eight patients, with a variety of hematological abnormalities including leukopenia, macrocytosis, and thrombocytopenia, had persistently abnormal FBCs. However there was no evidence of progression, and no patient has evolved to acute myeloid leukemia (AML). CONCLUSIONS: MDS is a complication of DS and may require supportive therapy. However, minor hematological abnormalities are common in adult DS patients, and may not signify underlying marrow disease.

    Introduction Tuberculosis (TB) is a major global health problem, and anti-tuberculosis drugs can cause severe adverse reactions. The aim of this study was to determine hematological and biochemical changes and associated risk factors in smear positive pulmonary tuberculosis patients undergoing treatment with standard protocols. Methods In a descriptive study, a total of 40 tuberculosis patients aged between 15–60 years were collected from hospitals in Khuzestan Province (Iran) from March 2013 to March 2014. The patients were treated with drugs (isoniazid, rifampicin, ethambutol, and pyrazinamide) during the initial two months, followed by isoniazid and rifampicin for the next four to six months. Activities of liver enzymes (ALT, AST, and ALP) and hematological parameters were recorded before and after treatment. Data were analyzed using paired samples t-test and Wilcoxon test by SPSS 16. Results After using drug treatments, hematological parameters (RBC, Hb, HCT, MCV, MCH, and MCHC), except platelet count, were changed significantly (p ≤ 0.001). Liver enzyme activities (ALT, AST, and ALP) were decreased significantly (p ≤ 0.001) after treatment. Conclusion In this study, changes of hematological and biochemical parameters have been observed in patients with pulmonary tuberculosis. It can be concluded that the anti-tuberculosis treatment is associated with changes of hematological parameters and liver enzymes.

    Objective: To evaluate the febrile neutropenic patients with hematological malignancies hospitalized in hematology clinic with poor hygiene standards. Methods: A total of 124 patients with hematological malignancies (69 male, 55 female) hospitalized in hematology clinic with poor hygiene conditions depending on hospital conditions, between January 2007 and December 2010, were evaluated, retrospectively. Results: In this study, 250 febrile neutropenia episodes developing in 124 hospitalized patients were evaluated. Of the patients, 69 were men (56%) and 55 women (44%). A total of 40 patients (32%) had acute myeloid leukemia, 25 (20%) acute lymphoblastic leukemia, 19 (15%) non-Hodgkin's lymphoma, 10 (8%) multiple myeloma, and 8 (8%) chronic myeloid leukemia. In our study, 56 patients (22%) were diagnosed as pneumonia, 38 (15%) invasive aspergillosis, 38 (15%) sepsis, 16 (6%) typhlitis, 9 (4%) mucormy-cosis, and 4 (2%) urinary tract infection. Gram-positive cocci were isolated from 52%(n = 20), while Gram-negative bacilli 42%(n = 16) and yeasts from 6% (n = 2) of the sepsis patients, respectively. The most frequently isolated Gram-positive bacteria were methicillin-resistant coagulase-negative staphylococci (n=18), while the most frequently isolated Gram-negative bacteria was Escherichia coli (n=10). Conclusions: Febrile neutropenia is still a problem in patients with hematological ma-lignancies. The documentation of the flora and detection of causative agents of infections in each unit would help to decide appropriate empirical therapy. Infection control pro-cedures should be applied for preventing infections and transmissions.

    Clinically effective anti-cancer drugs have to tread a narrow line between selective cytotoxicity on tumor cells and tolerable adverse effects against healthy tissues. This causes the failure of many potential cancer drugs in advanced clinical trials, hence signifying the importance of a comprehensive initial estimate of the cytotoxicity of prospective anti-cancer drugs in preclinical studies. In this study, the cytotoxicity of borrelidin, a macrolide antibiotic with a high cytotoxic selectivity for proliferating endothelial cells and leukemia cells, was tested on malignant and non-malignant breast cells. Highly metastatic breast cancer cell lines (MDA-MB-231 and MDA-MB-435) showed promising results and exhibited good sensitivity to borrelidin at low nanomolar concentrations, but borrelidin was cytotoxic to a non-malignant breast epithelial cell line (MCF10A) as well. Furthermore, although a high sensitivity of endothelial cells (human umbilical vein endothelial cells; HUVEC) and individual leukemia cell lines (Jurkat and IM9) to borrelidin was confirmed in this study, another leukemia cell line (HL60) and an immortalized endothelial cell line (EA.hy926) displayed a significantly decreased sensitivity. Reduced sensitivity to borrelidin was associated with elevated bcl-2 expression in these cell lines. In conclusion, the results presented show that borrelidin displays high and selective cytotoxicity against subgroups of cancer cells and endothelial cells, but, owing to its non-specific toxicity to non-malignant cells, its clinical application might be restricted because of likely adverse effects and limited efficacy in bcl2-overexpressing cancer cells.

  3. Targeting the PI3K/mTOR Pathway in Pediatric Hematologic Malignancies

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available A complex interplay of intracellular signaling networks orchestrates normal cell growth and survival, including translation, transcription, proliferation, and cell cycle progression. Dysregulation of such signals occurs commonly in many malignancies, thereby giving the cancer cell a survival advantage, but also providing possible targets for therapeutic intervention. Activation of the phosphatidylinositol 3-kinase (PI3K/protein kinase B (Akt/mammalian target of rapamycin (mTOR signaling pathway contributes to the proliferative advantage of malignant cells and may confer resistance to chemotherapy in various hematologic malignancies. The initial mTOR inhibitor, sirolimus (also known as rapamycin, was first discovered in 1975 in the soil of Easter Island. Sirolimus was originally developed as an anti-fungal agent given its macrolide properties, but was approved by the Food and Drug Administration (FDA in 1999 as an immunosuppressive agent for renal transplantation patients once its T cell suppression characteristics were recognized. Shortly thereafter, recognition of sirolimus’s ability to inhibit cellular proliferation and cell cycle progression brought sirolimus to the forefront as a possible inhibitor of mTOR. In the subsequent decade, the functional roles of the mTOR protein have been more fully elucidated, and this protein is now known to be a key regulator in a highly complex signaling pathway that controls cell growth, proliferation, metabolism, and apoptosis. This article discusses the dysregulation of PI3K/mTOR signaling in hematologic malignancies, including acute and chronic leukemias, lymphomas, and lymphoproliferative disorders. The current repertoire of PI3K/mTOR pathway inhibitors in development and clinical trials to date are described with emphasis upon pediatric hematologic malignancies (Figure 1. Investigation of small molecule inhibitors of this complex signaling network is an active area of oncology drug development.

  7. Monoamine oxidase inhibitors l-deprenyl and clorgyline protect nonmalignant human cells from ionising radiation and chemotherapy toxicity.

    Seymour, C B

    2003-11-17

    l-Deprenyl (R-(-)-deprenyl, selegiline) is an inhibitor of monoamine oxidase-B (MAO-B) that is known to protect nerve cells from a variety of chemical and physical insults. As apoptosis is a common mechanism of radiation-induced cell death, the effect of l-deprenyl on the survival of cultured cells and tissue explants was studied following exposure to gamma radiation. The results obtained were compared with the effects of the less-selective MAO-B inhibitor pargyline and the MAO-A inhibitor clorgyline. l-Deprenyl at a concentration of 10(-9) M protected the nontumorigenic cell line (HaCaT) and normal human urothelial explants from the effects of cobalt-60 gamma radiation, but did not protect tumorigenic human cell lines HaCaT-ras, HPV-transfected human keratinocytes (HPV-G cells), or PC3. Human bladder carcinoma explants were not protected. Clorgyline showed a smaller protective effect of normal cells, whereas pargyline had no effect. Radiation-induced delayed effects (genomic instability measured as delayed cell death) were prevented in normal cells by l-deprenyl but, interestingly, deprenyl appeared to increase the amount of delayed death in the tumorigenic cell lines. Studies using l-deprenyl prior to the exposure of nonmalignant cells to cisplatin showed that cell death due to this agent was also reduced. Treatment of cultures of nontumorigenic cells with l-deprenyl or clorgyline significantly increased the levels of the protein Bcl-2 following irradiation, but there was no such effect on the already-elevated levels of this protein in the tumour samples. Since the Bcl-2 has been shown to be an inhibitor of apoptosis or programmed cell death, this would imply that the protective effects of l-deprenyl and clorgyline involve activation of antiapoptotic pathways within the normal cell. This hypothesis is supported by data showing reduced levels of apoptosis in HaCAT cells and in normal bladder explant cultures following treatment with l-deprenyl.

    Full Text Available Pregnant impact on hematological parameters in the dogs was award in this study. Blood was collected in the cephalic vein of 32 female animals, clinically healthy, in different physiological condition. Hematological parameters that studied were RBC, WBC and platelets count, Hgb concentration, HCT, differential counting of leukocytes and erythrocyte indicators. The obtained results from the analysis showed that pregnancy can affect the values of hematological parameters. The number of erythrocytes, the level of hematocrit and hemoglobin concentration in pregnant animals resulted lower than in non-pregnant animals. No volatility resulted in the values of MCV, MCH and MCHC. In the pregnant animals group was found the increase of the circulating leucocytes number, of relative value of neutrophils and lymphocytes decrease. The pregnancy condition should be taken in consideration during the results interpretation of laboratory analysis.

    2008-01-01

    There is much interest in the potential use of Cox-2 selective inhibitors in combination with other cancer therapeutics. Malignancies of hematopoietic and non-hematopoietic origin often have increased expression of cyclooxygenase-2 (Cox-2), a key modulator of inflammation. For example, hematological malignancies such as chronic lymphocytic leukemia, chronic myeloid leukemia, Hodgkin's lymphoma, non-Hodgkin's lymphoma and multiple myeloma often highly express Cox-2, which correlates with poor patient prognosis. Expression of Cox-2 enhances survival and proliferation of malignant cells, while negatively influencing anti-tumor immunity. Hematological malignancies expressing elevated levels of Cox-2 potentially avoid immune responses by producing factors that enhance angiogenesis and metastasis. Cellular immune responses regulated by natural killer cells, cytotoxic T lymphocytes, and T regulatory cells are also influenced by Cox-2 expression. Therefore, Cox-2 selective inhibitors have promising therapeutic potential in patients suffering from certain hematological malignancies.

    The survival of patients with hematological malignancies has been significantly improved due to the development of new therapeutic agents. However, relapse remains a major matter for concern. Recently, T cells engineered with chimeric antigen receptor (CAR) were reported to show unprecedented responses in a range of hematological malignancies. The persistence of the CAR-T cell can last for years and tends toward long-term antitumor memory by which relapses can be effectively prevented. The primary side effects that appear in most clinical trials are cytokine release syndrome and neurotoxicity. However, these symptoms can be treated and reversed. In this review, we describe CAR structure and function and summarize recent advances in CAR-T cell therapy in hematological malignancies.

    Caspofungin is an echinocandin with proven efficacy in invasive candidiasis (IC) and invasive aspergillosis (IA). This multicenter, prospective, non-comparative, observational ProCAS study was aimed to assess the effectiveness and safety of caspofungin in adult hematological patients with IC or IA under everyday clinical conditions. Favorable outcomes included complete and partial responses on the last day of caspofungin therapy. Safety was assessed up to 14 days post-caspofungin. A total of 115 patients (69 male) with a median age of 52 years (range, 23-78 years) were analyzed. Underlying disease was acute myeloid leukemia in 45 patients (39%), and 21 (18%) were allogeneic stem cell transplant recipients. Thirty-four (29.5%) patients had a diagnosis of IA and 26 (22.6%) had IC (candidemia). The median duration of caspofungin therapy was 14 days (range, 1-100). The overall favorable response rate was 77% (20/26) for patients with IC (69% first-line) and 79% (27/34) for those with IA. Antifungal therapy with caspofungin was generally well tolerated, only two (1.7%) patients having a non-serious drug-related adverse reaction. These results suggest that caspofungin, either alone or in combination, should be considered an effective and safe option for the treatment of invasive mycoses in patients with severe hematological disorders.

    The bone marrow of 84 patients with hematological disorders was investigated using short inversion time inversion recovery sequence (STIR) on an 1.5 Tesla superconducting MRI system. Double echo times of 20 and 100 msec were applied to research the signal characteristics of the lesion and carry out quantitative analysis of the receiver operating characteristic curve (ROC). The hematological diseases included 19 cases of myelodysplastic syndrome (MDS), 18 of multiple myeloma (MM), 18 of chronic myelocytic leukemia (CML), 9 of aplastic anemia (AA), 8 of acute myelocytic leukemia (AML), 3 of chronic lymphocytic leukemia (CLL), 3 of myelofibrosis, and 3 others. Using STIR with double echo times, bone marrow showed high signal intensity (SI) on short TE and low SI on long TE in MDS and CML; high SI on short and long TE in myelofibrosis and CLL; high SI on short TE and high to moderately high SI on long TE in MM; and low SI on short and long TE in AA. Quantitative analysis of 33 patients showed high sensitivity and specificity in AA (81% and 94%, respectively) and moderate sensitivity and high specificity in MM (61%, 88%). CML and MDS were similar with low sensitivities (40%, 41%) and high specificities (80%, 78%). Differential diagnosis between CML and MDS was difficult using STIR with the double echo time method.

    Cardiovascular and related disorders are one of the most common disease prevailing all over the world. Hyperlipidemic condition have been largely considered in the treatment of cardiovascular diseases. The present study was carried out to investigate the effect of Ambrex on hematological factors in hyperlipidemic rats and untreated hyperlipidemic rats. In this study, eighteen rats were randomly divided into three groups of six animals each. The groups received normal diet (Control Group A) high fat diet (HFD group B) and Ambrex treatment (Group C). After the study period, White Blood Cell (WBC), Red Blood Cell (RBC), hematocrit (HCT), Hemoglobin, platelet (PLT), lymphocytes, monocytes, granulocytes, Mean Corpuscular Hemoglobin Concentration (MCHC), plateletcrit (PCT), Mean Corpuscular Volume (MCV), Platelet Distribution Width (PDW), red cell distribution-standard deviation (RDW-SD), red cell distribution-correlation variance (RDW-CV), micro red blood cell (pRBC), macroRBC were measured using digital cell counter (MS9-3s). Hyperlipidemia increases markedly the PLT count. Administration of Ambrex appeared to significantly increase WBC, Lymphocytes, granulocytes. However, erythrocyte indices does not show statistically significant variations among the test groups and control groups. The findings demonstrated that Ambrex does not cause any significant undesirable alterations in hematological factors in male rats. Ambrex also enhances white blood cell concentration and lymphocytes which probably stimulate the immune defense mechanism.

    2016-01-01

    Leptin is an adipose-derived cytokine that has an important role in bodyweight homeostasis and energy balance. There are a number of studies which have suggested that leptin and its receptors dysregulation play a critical role in the development of malignancies including hematological malignancies, mainly via activation of the JAK/STAT pathway which regulates downstream signaling pathways such as PI3K/AKT signaling and ERK1/2. In this review, current understandings of leptin/leptin receptors mediated pathogenesis in various lymphoid malignancies are described. Blocking of the leptin receptor might be a unique therapeutic approach for many hematological malignancies.

  17. In the sandbox: palliative care and hematologic malignancies.

    2014-02-01

    Palliative care specialists have had little involvement in the care of patients with hematologic malignancies. The reasons for this are not clear, because these patients certainly face a significant symptom burden, and many hematologic malignancies are either incurable or carry poor prognoses. For example, acute myeloid leukemia (AML) in patients over age 60 has a 5-year survival of less than 10%, akin to pancreatic cancer. Although most oncologists would agree with involving palliative care specialists in the case of advanced pancreatic cancer, few seem to consider this in the context of AML. Why should AML be any different?

  18. Effects of Endurance and Circuit Resistance Trainings on Lipid Profile, Heart Rate, and Hematological Parameters in Obese Male Students

    2014-12-01

    Full Text Available Studies have shown that different exercise ways are of the most important factors that affect cardiovascular risk factors and hematological parameters. This present paper aims to study the effects of two methods of endurance and resistance training on lipid profiles, heart rate, and hematological parameters in obese male students. 36 obese students were purposefully selected and randomly divided into three groups of 12 including endurance exercise, resistance exercise, and control. Exercise program was performed 3 times a week for 8 weeks, with a specific duration and intensity in both endurance and resistance exercise groups. Blood sampling was done after 14 fasting before the trial and 48 hours after the last training session. Results showed that both resistance and endurance exercises significantly increased HDL-C, Hct, and Hb and significantly decreased TC, TG, and resting heart rate (P>0.05. Also, Resistance exercise significantly increased the PLT and decreased LDL-C (P>0.05. However, WBC and RBC showed no significant change in the resistance and endurance exercise groups (P>0.05. In addition, no significant difference was observed between endurance and resistance exercise (P>0.05. In general, both endurance and resistance exercises can affect the lipid profile and hematological parameters and also reduce the resting heart rate. Therefore, they can be considered as an appropriate and non-medication approaches to prevent and reduce the incidence of cardiovascular diseases and obesity-related disorders in obese male adolescents.

    The clinical importance of hematologic testing in avian veterinary medicine is reflected in the increasing number of studies for the establishment of hematologic RIs of Strigiformes and other species. Age is an important physiologic factor in birds and the effect on hematology variable should be understood. The objective of this study was to determine baseline data of hematologic variables in 5 species of Iberian Strigiformes in different age classes. Nocturnal birds of prey were sampled at Wildlife Health Centers. Packed cell volume was determined by the microhematocrit centrifugation method, and RBC and WBC counts were determined using the direct hemocytometer count method with Natt and Herrick solution. Hemoglobin concentration was measured spectrophotometrically. The MCV, MCHC, and MHC were calculated using the standard formulas. The differential WBC count was performed by the routine microscopic evaluation of 200 cells on a blood smear manually stained with Wright stain. Thrombocyte blood count estimate was obtained from the blood film. No differences were observed between juveniles and adults for any variable evaluated in Tawny owl, Little owl, Scops owl, Long-eared owl, and Barn owl. In addition, PCV, RBC, and HGB of chicks were statistically significantly lower than in juveniles and adults, and total WBC was significantly higher in Tawny owl, Little owl, Scops owl, and Long-eared owl. Our findings provide evidence that laboratory data from chicks of Strigiformes are different compared to juveniles and adults; therefore, separate RIs were defined. © 2017 American Society for Veterinary Clinical Pathology.

    Full Text Available Hematopoietic stem cell transplantation (HSCT is usedfor various hematologic malignancies seen in childrenand adults. There may be several complications before,during, and after the HSCT. Just one of them is endocrinologiccomplications, since endocrine system (particularlythe pituitary gland, thyroid gland, adrenal glands, andgonads is highly sensitive against various stress. Chemotherapyand/or total body irradiation used as preparativeregimens and immunosuppressive agents (especiallycorticosteroids used for the graft-versus-host diseasecan cause hormonal disorders. Time elapsed after theHSCT, transplantation type (autologous or allogeneic,preparative regimen choice, age, and gender determinesthe complications. A multidisciplinary management containinga specialist of endocrinology for these patients ispreferred. In this report, we reviewed the endocrinologiccomplications that observed after the HSCT in childrenand adults referring to the recent literatures. J Clin ExpInvest 2012; 3(1: 149-156

    2013-12-01

    Pulmonary hypertension (PH) has emerged as a major complication of several hematologic disorders, including hemoglobinopathies, red cell membrane disorders, chronic myeloproliferative disorders, and splenectomy. With the exception of sickle cell disease, there are a limited number of studies systematically evaluating the prevalence of PH using the gold standard right heart catheterization in these disorders. The cause of the PH in patients with hematologic disorders is multifactorial, and a thorough diagnostic evaluation is essential. More importantly, there are virtually no high-quality data on the safety and efficacy of PH-targeted therapy in this patient population.

    Radiologically visible parenchymal changes (small opacities >= 1/0;ILO 1980 classification) were present in 20% of a sample of workers (N=174), employed for 20 years (median) in an asbestos cement plant. Exposure-response relationships were found, after controlling for age and smoking habits. In a sample of asbestos cement workers with symptoms and signs suggestive of pulmonary disease (N=33), increased lung density measured by x-ray computed tomography, and reduced static lung volumes and lung compliance was found. In a cohort of asbestos cement workers (N=1.929) with an estimated median exposure of 1.2 fibres/ml, the mortality from non-malignant respiratory disease was increased in comparison to a regional reference cohort (N=1.233). A two-to three-fold increase of non-malignant respiratory mortality was noted among workers employed for more than a decade in the asbestos cement plant, compared to cement workers (N=1.526), who in their turn did not experience and increased risk compared to the general population. In the cohorts of asbestos cement and cement workers, there was a tow-to three-fold increased incidence of cancer in the right part of the colon, compared to the general population as well as to external reference cohorts of other industrial workers (N=3.965) and fishermen (N=8.092). A causal relation with the exposure to mineral dust and fibres was supported by the findings of higher risk estimated in subgroups with high cumulated asbestos doses or longer duration of cement work. The incidence of cancer in the left part of the colon was not increased. Morbidity data, but not mortality data, disclosed the subsite-specific risk pattern. Both asbestos cement workers and cement workers has an increased incidence of rectal cancer, compared with the general population, and with the fishermen. The risk was, however, of the same magnitude among the other industrial workers. 181 refs.

    Activation of estrogen receptor-β (ERβ) is an important mechanism for colon cancer prevention. Specific sorghum varieties that contain flavones were shown to activate ER in non-malignant colonocytes at low concentrations. This study aimed to determine positive interactions among estrogenic flavonoids most relevant in sorghum. Apigenin and naringenin were tested separately and in combination for their ability to influence ER-mediated cell growth in non-malignant young adult mouse colonocytes (YAMC). Sorghum extracts high in specific flavanones and flavones were also tested. Apigenin reduced ER-mediated YAMC cell growth comparable to physiological levels of estradiol (E₂, 1 nM) at 1 μM; naringenin had similar effect at 10 μM. However, when combined, 0.1 μM apigenin plus 0.05 μM naringenin produced similar effect as 1 nM E₂; these concentrations represented 1/10th and 1/200th, respectively, of the active concentrations of apigenin and naringenin, demonstrating a strong enhanced action. A sorghum extract higher in flavones (apigenin and luteolin) (4.8 mg g(-1)) was more effective (5 μg mL(-1)) at activating ER in YAMC than a higher flavanone (naringenin and eriodictyol) (28.1 mg g(-1)) sorghum extract (10 μg mL(-1)). Enhanced actions observed for apigenin and naringenin were adequate to explain the level of effects produced by the high flavone and flavanone sorghum extracts. Strong positive interactions among sorghum flavonoids may enhance their ability to contribute to colon cancer prevention beyond what can be modeled using target compounds in isolation.

    This randomised, double-blind, double-dummy, parallel-group multicentre study assessed the impact of a total daily dose of 60-80 mg oral oxycodone prolonged-release (PR)/naloxone PR (OXN PR) as fixed-ratio combination for patients with opioid-induced constipation (OIC) having moderate-to-severe, non-malignant pain. During pre-randomisation patients receiving opioids for moderate-to-severe non-malignant pain were converted to oxycodone PR (OXY PR) and titrated to an effective analgesic dose. During randomisation 265 patients on a stable OXY PR dose (60-80 mg/day) and with OIC were included in the full analysis population to receive OXN PR or OXY PR alone. Primary outcome was improvement in symptoms of constipation as measured by the Bowel Function Index (BFI). Secondary/exploratory outcomes examined analgesic efficacy and other bowel function parameters. After 4 weeks of treatment, patients receiving OXN PR showed a significant improvement in bowel function compared with those in the OXY PR group (-14.9; 95% CI: -17.9, -11.9; pPR had a median number of 3.0 complete spontaneous bowel movements (CSBM) per week compared with only 1.0 for OXY PR alone. Laxative intake was lower in the OXN PR than the OXY PR group. Furthermore, improvements in bowel function were achieved without loss of analgesic efficacy; pain intensity scores were comparable between the groups and consistent for duration of the study. Most frequently reported adverse events were consistent with those reported for opioid analgesics; no new or unexpected adverse reactions attributable to OXN PR used in higher doses were observed. This study shows that the fixed-ratio combination of OXN PR is superior to OXY PR alone in terms of bowel function, while providing effective equivalent analgesia.

    leukocyte and granulocytic counts and decreases in lymphocytic counts were found in infected cattle. In contrast, no such hematological anomalies were found in presumably Babesia-infected buffaloes. Frequent occurrence of babesiosis among apparently healthy bovines in Egypt, suggests the need for appropriately designed prevalence studies in this country. Infected bovine, but not buffalo, populations often present hematological disorders compatible with intravascular hemolysis and thrombocytopenia.

    1997-01-01

    Full Text Available Immunocompromised individuals infected with Strongyloides stercoralis may develop severe hyperinfection or disseminated disease with high mortality. Patients with hematological malignancies are at risk because of immunodepression produced either by the disease or its treatment. A prospective study was undertaken at the Hospital de Clínicas de Porto Alegre, from July 1994 to July 1995. Seventy-two (HIV negative, had 3 stool samples collected at different days and had not received recent anti-helmintic therapy. Larvae, isolated in a modified Baermann method, were found in 6 patients, with a resultant prevalence of 8.3%. No complicated strongyloidosis was documented. The positive result for S. stercoralis larvae was significantly associated (p < 0.001 with eosinophilia. Knowledge of prevalence figures and incidence of severe disease is important to adequate guidelines for empirical treatment besides the rigorous search for strongyloidosis in patients with hematological malignancies.

    In this study, we evaluated the efficacy of virtual microscopy as the primary mode of laboratory instruction in undergraduate level clinical hematology teaching. Distance education (DE) has become a popular option for expanding education and optimizing expenses but continues to be controversial. The challenge of delivering an equitable curriculum to distant locations along with the need to preserve our slide collection directed our effort to digitize the slide sets used in our teaching laboratories. Students enrolled at two performance sites were randomly assigned to either traditional microscopy (TM) or virtual microscopy (VM) instruction. The VM group performed significantly better than the TM group. We anticipate that this approach will play a central role in the distributed delivery of hematology through distance education as new programs are initiated to address workforce shortage needs.

  14. The targeting of immunosuppressive mechanisms in hematological malignancies

    The adaptive immune system has the capacity to recognize and kill leukemic cells. However, immune tolerance mechanisms that normally protect healthy tissues from autoimmune effects prevent the development of effective antitumor immunity. Tumors use several different immunosuppressive mechanisms...... to evade otherwise effective T-cell responses. A growing number of immune evasion mechanisms have been characterized mainly in solid tumors. In hematological malignancies, less is known about how different immune escape mechanisms influence tumor immune evasion and the extent of their impact on ongoing...... immune responses. The present review highlights the potential role of three well-defined immunosuppressive mechanisms in hematological malignancies: (i) inhibitory T-cell pathways (especially programmed death ligand 1/programmed death 1 (PD-L1/PD-1)), (ii) regulatory immune cells, and (iii) metabolic...

    The medical research and training enterprise in the United States is complex in both its scope and implementation. Accordingly, adaptations to the associated workforce needs present particular challenges. This is particularly true for maintaining or expanding national needs for physician-scientists where training resource requirements and competitive transitional milestones are substantial. For the individual, these phenomena can produce financial burden, prolong the career trajectory, and significantly influence career pathways. Hence, when national data suggest that future medical research needs in a scientific area may be met in a less than optimal manner, strategies to expand research and training capacity must follow. This article defines such an exigency for research and training in nonneoplastic hematology and presents potential strategies for addressing these critical workforce needs. The considerations presented herein reflect a summary of the discussions presented at 2 workshops cosponsored by the National Heart, Lung, and Blood Institute and the American Society of Hematology.

    The effects of dimethoate on hematological, biochemical parameters, and behavior were investigated in Oncorhynchus mykiss exposed to sublethal concentrations of 0.0735, 0.3675, and 0.7350 mg/l for 5, 15, and 30 days. Significant decrease was determined in erythrocyte and leukocyte counts, hemoglobin, hematocrit, MCV, and MCH, which was pronounced after prolonged exposure indicating the appearance of microcytic hypochromic anemia. There were no prominent changes in thrombocyte and MCHC. The glucose concentration showed an ascending pattern that proved to be positively correlated with duration. The protein concentration declined in higher dimethoate concentrations following 15 and 30 days. Negative and significant correlation was detected between glucose and protein concentrations. The fish showed remarkable behavioral abnormality such as loss of balance, erratic swimming, and convulsion. Present findings revealed that dimethoate exerts its toxic action even in sublethal concentrations and hematological parameters and abnormal behavior may be sensitive indicators to evaluate pesticide intoxication.

    2013-01-01

    Drug 'repurposing', that is, using old drugs for new indications, has been proposed as a more efficient strategy for drug development than the current standard of beginning with novel agents. In this review, we explore the scope of drug repurposing in pediatric hematology oncology and in pediatrics in general. Drugs commonly used in children were identified using the Harriet Lane Handbook (HLH) and searched in PubMed for different uses. Additional drugs were identified by searching PubMed and Google.com for 'drug repurposing' or 'drug repositioning'. Almost 10% of drugs with primary uses in pediatrics have been repurposed in pediatric hematology oncology or pediatrics. The observant clinician, pharmacologist and translational bioinformatician, as well as structural targeting, will have a role in discovering new repurposing opportunities.

    Cancer-related problems are seen frequently by the emergency physician. More difficult presentations are seen with premonitory symptoms, paraneoplastic syndromes, and nonspecific lesions. Dermatologic paraneoplastic syndromes are numerous, nonspecific, and consist of hamartomatous growths, texture changes, new hair growth, or changes in skin color. Alteration of skin color may be of practically any color, localized or diffuse, and of sudden or indolent onset. Hormone production by tumors may lead to acne, hirsutism, gynecomastia, or a cushingoid appearance. Pruritus may herald the onset of leukemia or lymphoma and be intolerable, as with erythroderma. All suspicious presentations require thorough investigation for underlying disease. Metastasis to skin is not common and implies a poor prognosis if seen. Most metastases are seen on the head and neck, anterior chest wall, and abdomen. Basal cell and squamous cell carcinomas commonly occur in sun-exposed areas. Basal cell is locally destructive, whereas squamous cell occasionally metastasizes to local lymph nodes. Malignant melanoma is the leading fatal illness originating in skin, with a dramatic rise in incidence. It is classically described as asymmetric with irregular borders, is elevated, and shows color variegation; however, melanoma may present atypically, particularly in non-whites. Kaposi's sarcoma lesions are well-demarcated, symmetric, smooth nodules that appear purplish-brown, particularly if below the knee (owing to venous stasis). The closely interrelated structures of the eye and orbit are easily disturbed, leading to the presenting symptoms of visual disturbances, exophthalmos, pain, and ocular motility disorders. Primary tumors are not unusual and may include retinoblastoma, rhabdomyosarcoma, and melanoma. Equally common are metastatic lesions, most commonly lung and breast carcinoma. An estimation of the malignancy of bony lesions can be made by assessing the zone of transition, periosteal reaction

    2016-12-01

    A previous study provided information regarding the quality of in-clinic veterinary biochemistry testing. However, no similar studies for in-clinic veterinary hematology testing have been conducted. The objective of this study was to assess the quality of hematology testing in veterinary in-clinic laboratories using results obtained from testing 3 levels of canine EDTA blood samples. Clinicians prepared blood samples to achieve measurand concentrations within, below, and above their RIs and evaluated the samples in triplicate using their in-clinic analyzers. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index, and agreement between in-clinic and reference laboratory instruments. Suitability for statistical quality control was determined using adaptations from the computerized program, EZRules3. Evaluation of 10 veterinary in-clinic hematology analyzers showed that these instruments often fail to meet quality requirements. At least 60% of analyzers reasonably determined RBC, WBC, HCT, and HGB, when assessed by most quality goal criteria; platelets were less reliably measured, with 80% deemed suitable for low platelet counts, but only 30% for high platelet counts, and automated differential leukocyte counts were generally considered unsuitable for clinical use with fewer than 40% of analyzers meeting the least stringent quality goal requirements. Fewer than 50% of analyzers were able to meet requirements for statistical quality control for any measurand. These findings reflect the current status of in-clinic hematology analyzer performance and provide a basis for future evaluations of the quality of veterinary laboratory testing. © 2016 American Society for Veterinary Clinical Pathology.

    Full Text Available Abstract Background Hematological abnormalities are a common complication of HIV infection. These abnormalities increase as the disease advances. Bone marrow abnormalities occur in all stages of HIV infection. Methods Two hundred HIV infected individual were screened for hematological abnormalities from March 2007–March 2008. Absolute CD4 cell count analysis was carried out by flowcytometry. Depending on the results of the primary screening further investigations were performed, like iron studies, hemolytic work up, PNH work up and bone marrow evaluation. Other investigations included coagulation profile, urine analysis, blood culture (bacterial, fungal, mycobacterial, serology for Epstein Barr virus (EBV, Cytomegalovirus (CMV, Hepatitis B and C, and Parvo B19 infection. Results The most common hematological abnormality was anemia, seen in 65.5% (131/200 patients. Iron deficiency anemia was seen in 49.2% (/200 cases while anemia of chronic disease occurred in 50.7% (/200 cases. Bone marrow evaluation was carried out in 14 patients out of which staging marrow was performed in 2 cases of non-Hodgkin's lymphoma (NHL and did not show any bone marrow infiltration. In remaining12 cases bone marrow was done for evaluation of pancytopenia. Among patients with pancytopenia 50% (6/12 showed granulomas (4 were positive for AFB, 2 were positive for fungal cryptococci, 25% (3/12 showed hemophagocytosis. There was a strong negative correlation between anemia and CD4 counts in this study. Thrombocytopenia was seen in 7% (14/200 cases and had no significant correlation with CD4 counts. No patient had absolute neutrophil count (ANC Conclusion Anemia in HIV patients can be a good clinical indicator to predict and access the underlying immune status. Patients should be investigated for hematological manifestations and appropriate steps should be taken to identify and treat the reversible factors.

  5. Using a Hematology Curriculum in a Web Portfolio Environment

    2011-03-01

    Full Text Available In 2005 the European Hematology Association developed the European Hematology Curriculum. This was distributed as a printed booklet and the intention was that junior hematologist could use it for personal competence development. In the EU-funded project H-net this Curriculum has been adapted into the a web environment by using RDF and placed inside a web portfolio system. How this is done is further described in this article. Furthermore, the possibilities of reusing the curriculum in ways that was not initially intended is described, such as describing Learning Resources inside the web-portfolio system with how they relate to different parts of the curriculum. That way a search for learning resources inside the portfolio by using the curriculum is enabled. And, since the medical field of hematology is closely related to other medical fields the design of the web-version of the curriculum was done in a way that builds for possible combination with any other curriculum in another medical field.

Material and Method: Between 2000 and 2013, 1700 adult patients underwent PNL for the treatment of kidney stones in our institution. Four of these patients had a history of HM and considered to be HM group (n=4. Ten elderly (>65 years patients who had no history of operation, HM or any other co-morbide diseases were chosen as the control group (n=10. Surgical parameters, success rates, additional treatments and complications were evaluated. Results: Statistical analyses showed no significant differences between HM and control group according to stone area, operation time, fluoroscopy time, hospitalization time, %u2206Hb, blood transfusion rates and INR values (p>0.05. Statistical analyses revealed no significant differences between HM and control groups according to the success rates (p=0.470. Statistical analyses revealed no significant difference between groups for additional treatment requirements (p=0.882. No major perioperative complication was seen in both of the groups. Discussion: The treatment of kidney stone disease by PNL in patients with hematological malignancy is feasible, safe and effective. However, close cooperation with the Hematology Department before the operation is mandatory.

    The majority of patients with hematological malignancies (HM) may experience troublesome symptoms and complicating clinical syndromes throughout all phases of disease. Therefore, among the current concepts concerning the comprehensive management of hematological patients, palliative care should exert a more ever expanding role, in particular in the advanced phases of disease, as there are special clinical needs (such as blood transfusions and anti-infective treatments), presented by this peculiar category of cancer patients. However, reported experiences on advanced HM patients claimed a too intensive level of medical care during the last week of life for which the needs of future and collaborative researches in order to set a proper allocation of medical resources and the optimal end-of-life care in the hematologic setting are highly awaited. Indeed, the most important aspect of caring for these suffering patients is to ameliorate or restore their quality of life (QoL) though a highly humanized approach, whereas technological and pharmacological measures should be limited enough to control the symptoms burden and the several kinds of sufferance that may complicate the final phase of disease course.

Malarial patient exhibit several divergent values in their blood cell parameter as well as changes in concentration of normal serum ferritin level. The study was intended to observe the concentration of serum ferritin level and estimation of hematological feature among malaria patients in Assam. Materials and Methods: During the period from August 2012 to January 2013, a total of 77 blood samples have been collected from 77 individuals suspected with malaria from different malaria endemic districts of Assam. Results: A total of 36 cases were found to be malaria positive of which 25 were symptomatic and 11 were asymptomatic. Overall the percentage of parasitaemia was found 0.1-15%. Distribution of malaria cases was observed in all age groups and both the sexes. Hematological values among the malaria positive patients revealed that about 89% were having anaemia, 66.67% with Thrombocytopenia and 47% Lymphocytopenia. Iron deficiency anaemia was recorded in 63.87% of the patients. Other haematological status includes 30.56% individual with Granulocytosis and 50.00% subjects with low Mean platelet volume etc. Results also showed that the serum ferritin level in the malaria positive population ranged in from 70 ng/ml to 300 ng/ml, with a mean value of 114 ng/ml. Conclusion: In our study, hematological abnormality and low serum ferritin level is observed as an imperative marker for identification of malaria patients.

    Secondary osteosarcoma arising after the treatment of hematologic malignancies other than Hodgkin's lymphoma is rare. We report two cases of secondary osteosarcoma arising after treatment for childhood hematologic malignancies (non-Hodgkin's lymphoma and lymphoblastic leukemia). A 10-year-old boy, at the age of 3, was diagnosed with non-Hodgkin's lymphoma. He received chemotherapy, radiation, and bone-marrow transplantation and then was in complete remission. At 6 years, he complained of increasing pain of the right thigh and was diagnosed with osteoblastic osteosarcoma. A 26-year-old man, at the age of 6, was diagnosed as having acute lymphoblastic leukemia (ALL). He received chemotherapy, radiation, and peripheral blood stem cell transplantation (PBSCT). At 11 years after PBSCT, he visited with the complaint of left lumbar swelling. He was diagnosed with chondroblastic osteosarcoma. In both cases alkaline phosphatase (ALP) had already increased prior to the onset of the symptom. We should rule out secondary osteosarcoma at the abnormal elevation of ALP during clinical follow-up of patients after treatment of childhood hematologic malignancies. PMID:19961270

    Full Text Available Introduction: Hairy cell leukemia is a rare chronic B-cell disorder that follows an indolent but progressive course. This disorder is characterized by pancytopenia, splenomegaly, bone marrow fibrosis and the presence of atypical lymphoid cells with hairy projections in peripheral blood, bone marrow and spleen. Treatment is mainly with nucleoside analog cladribine, which induces complete remission in up to 85% cases. Materials and Methods: This is a retrospective analysis of Hairy cell Leukemia cases diagnosed and treated in the Department of Hematology, All India Institute of Medical Sciences, New Delhi between 2002 and 2013. Various parameters such as clinical features, laboratory parameters including complete blood cell count, bone marrow findings, cytochemistry, immunophenotyping by flowcytometry or immunohistochemistry, treatment protocol and complications secondary to treatment and relapse were reviewed. Results: A total of 35 cases were diagnosed during this period of 12 years of which 27 received cladribine and went in to remission. Median follow-up duration was 26 months. 5 (18% cases had a relapse and all relapsed cases achieved second remission with cladribine; however, there was no case of second malignancy in our cohort. Conclusion: Cladribine has emerged as the treatment of choice for hairy cell leukemia given that the overwhelming majority of patients achieve long-lasting complete remissions. Upon relapse, these patients could be successfully salvaged with cladribine retreatment.

    Full Text Available Hypomethylating drugs are useful and approved in the management of myelodysplastic syndromes (MDS and Chronic Myelomonocytic Leukemia (CMML. However, phase 2 and 3 studies that assessed these agents in MDS, have included only a small number of CMML, and there are only few specific reports on CMML patients. Azacitidine is actually authorised for the treatment of CMML patients with 10-29% marrow blasts without myeloproliferative disorder who are not eligible for haematopoietic stem cell transplantation. This hypomethylating agent in MDS is known to cause transient cytopenias, most often occurring in the first 2 cycles. Here we report a case of atypical prolonged hematologic toxicity during azacitidine treatment in a CMML patient and we also review the literature regarding the efficacy of the drug and the management of hematologic adverse effects in specific CMML setting.

    Full Text Available Hematological and biochemical values are important for diagnosis of clinical signs, showing how disease processes change. This is the first report to demonstrate hematological and serum biochemical values of white ibis (Threskiornis melanocephalus in Thailand, which are rare species in tropical countries. The study was carried out in ten healthy white ibises (male, n=5; female, n=5, at the age of 4 years from Khow Khoew Open Zoo, Chon Buri province, Thailand. The results revealed the following information: total red blood cell, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cell, percentage of lymphocyte,percentage of heterophil, percentage of monocyte, percentage of eosinophil, percentage of basophil and thrombocyte of white ibis were 2.78±0.70 × 106 cells/µl, 18.75±1.32 g/dl, 46.00±3.59%, 173.51±38.52 fl, 70.73 ±15.42 g/dl, 40.82±1.65 pg, 1.49± 0.66 × 104 cells/µl, 89.70±6.40%, 8.50±6.34%, 0.50±0.97%, 0.90±1.29%, .30±0.95% and 16.2±0.49 × 103 cells/µl, respectively. Serum biochemistry values i.e. serum glucose, serum creatinine, serum glutamic oxaloacetic transaminase, and serum glutamic pyruvic transaminase of white ibis were 12.55±1.90 mmol/dl, 69.95±13.05 mmol/l, 204.82±56.76 IU/L and 30.43±8.66 IU/L, respectively. Hematological and biochemical values between males and females white ibis were not significantly different (P>0.05.

    The rice field frog Hoplobatrachus rugulosus is an important anuran species found in wetlands throughout Thailand. At present, the hematological parameters of wild populations are unknown. Therefore, hematological and morphological characteristics of peripheral blood cells of wild-caught H. rugulosus were examined. Thirty-three adult frogs (17 male and 16 female frogs) were collected from a natural population in Nan Province, northern Thailand during the wet season of 2014. Blood samples were analyzed by packed cell volume (PCV) and blood cell counts from hemocytometer and Giemsa-stained blood smears. The mean PCV of male frogs (30.70% ± 6.07%) was significantly higher than that of the female frogs (25.09% ± 4.85%). The mean number of lymphocytes and neutrophils also showed significant sex-related differences. Moreover, the morphometric analysis of blood cells revealed dimensions as follows:erythrocytes (17.96 ± 1.44 µm length × 11.50 ± 1.09 µm width), immature erythrocytes (14.91 ± 2.20 µm diameter), thrombocytes (13.93 ± 3.14 µm length × 7.05 ± 1.31 µm width), lymphocytes (11.01 ± 2.69 µm diameter), monocytes (12.04 ± 2.40 µm diameter), neutrophils (12.58 ± 2.08 µm diameter), basophils (13.60 ± 2.17 µm diameter) and eosinophils (12.33 ± 2.95 µm diameter). Overall, the hematological parameters obtained in this study could be regarded as the first report and a crucial baseline data of wild H. rugulosus in Thailand that can be used for monitoring the health status of this anuran.

    2015-01-01

    Full Text Available Background: Normal hematological indices has been determined in Nigerian newborns and found to be lower compared to their Caucasian counterparts. This was attributed to genetic factors. Malaria is endemic in Nigeria and is one of the major causes of ill health and death. Anemia is an important manifestation of malaria. Resistance by malaria parasites to antimalarial drug exacerbates the situation by continuous hemolysis. Aim: To determine the hematological indices in febrile newborn with malaria parasitemia. Materials and Methods: One-hundred fifty neonates (0-28 days with fever admitted into the Newborn Unit of University of Calabar Teaching Hospital, over a 6 months period, were recruited consecutively. Blood film for malaria parasites and samples for full blood count were obtained and sent to the laboratory before commencement of the treatment. Data analysis was with SPSS version 14. Results: One-hundred fifty babies were recruited into the study. Most (85.3% of the babies were aged ≤7 days. Six babies (4% had malaria parasitemia. Plasmodium falciparum was the only species identified. All the babies that had parasitemia were anemic (mean hemoglobin [Hb] concentration of 12.6 g/dl even when parasite count was low (average of 30.6/µl though this could not be attributed solely to malaria. None of these neonates was transfused. All the other hematological indices were within the normal range of healthy newborn population irrespective of parasitization. Conclusion: Neonatal malaria does occur in our environment. While it does not affect the white blood indices, it lowers neonatal Hb. It is recommended that Hb concentration be estimated in newborns with malaria to reduce infant morbidity and mortality in our environment.

    Podar, Klaus; Anderson, Kenneth C

    2005-02-15

    Besides its role as an essential regulator of physiologic and pathologic angiogenesis, vascular endothelial growth factor (VEGF) triggers growth, survival, and migration of leukemia and multiple myeloma cells; plays a pivotal role in hematopoiesis; inhibits maturation of dendritic cells; and increases osteoclastic bone-resorbing activity as well as osteoclast chemotaxis. Dysregulation of VEGF expression and signaling pathways therefore plays an important role in the pathogenesis and clinical features of hematologic malignancies, in particular multiple myeloma. Direct and indirect targeting of VEGF and its receptors therefore may provide a potent novel therapeutic approach to overcome resistance to therapies and thereby improve patient outcome.

    The hematologic and immunologic functions of the Skylab 3 astronauts were monitored during the preflight, inflight, and postflight phases of the mission. Plasma protein profiles showed high consistency in all phases. A transient suppression of lymphocyte responsiveness was observed postflight. A reduction in the circulating blood volume due to drops in both the plasma volume and red cell mass was found. The loss of red cell mass is most likely a suppressed erythrypoiesis. The functional integrity of the circulating red cells did not appear to be compromised in the course of flight.

    The increased industrial applications of nanoparticles (NPs) augment the possibility of their deposition into aquatic ecosystems and threatening the aquatic life. So, this study aimed to provide a comparable toxicological effects of nano-CuO and bulk CuO on a common freshwater fish, Oreochromis niloticus. Fish were exposed to two selected doses (1/10 and 1/20 of the LC50/96 h) of both nano-/bulk CuO for 30 days. Based on the studied hematological parameters (RBCs count, hemoglobin content and hematocrit%), the two selected concentrations of CuO in their nano- and bulk sizes were found to induce significant decrease in all studied parameters. But, nano-CuO-treated fish showed the maximum decrease in all recorded parameters among the all studied groups especially at the low concentration of 1/20 LC50/96 h. Hematological status was also confirmed using the calculated blood indices (MCV, MHC and MCHC). In case of bulk CuO-treated groups, the significant decrease in the studied hematological parameters was not followed by any change in MCV and MCH (normocytic anemia), while fish that exposed to NPs showed a significant increase in all calculated blood parameters reflecting erythrocytes swelling which is related to the intracellular osmotic disorders (macrocytic anemia). Regarding metal bioaccumulation factor, the results showed that CuO NPs had more efficiency to internalize fish tissues (liver, kidneys, gills, skin and muscle). The accumulation pattern of Cu metal was ensured by histopathological investigation of liver, kidneys and gills. The histopathological analysis revealed various alterations that varied between adaptation responses and permanent tissue damage.

    The population of old people has increased and nutritional disorders are common among them. The assessment of nutritional status and dietary intakes of this population is necessary in order to improve their nutritional status and reduce risk to infection and mortality. In the present study, data on the nutritional status of healthy elderly and centenarians is provided. Participants were free-living healthy volunteers (39 centenarians; 11 male and 28 female and 44 elderly in their 70s; 13 male and 31 female). Their nutritional status was assessed by anthropometric measurements, hematological and biochemical variables. Activities of daily living (ADL) of 11 items were scored depending upon their activities with a maximum score of 5.0. Dietary survey by food recording was done for 2 days and food models were used to obtain the best estimate of food intake. Energy and nutrient intakes were compared with Japanese recommended dietary allowances (RDAs). The elderly had complete independence of physical activities, good sensory function and cognitive abilities. The physical activities of male centenarians were between the category of completely independent and independent but slow. In female centenarian participants, their physical activities were independent but slow or independent with difficulty. The functions of auditory acuity and eyesight of the centenarians were poor but their cognitive abilities were still good. The elderly subjects had short stature whereas their body weight and body mass index (BMI) were not low, especially among the women, compelling female elderly to reduce their food intake to control the weight. Energy intake of female centenarians was low. The ADL in the female centenarians was positively related to energy, suggesting that the low energy intake of the female centenarians was mainly due to their low ADL. Anthropometric, hematological and biochemical variables of the centenarians were lower or near the lower reference limit except serum lipids

En hematología hay diversas entidades nosológicas y causas que pueden requerir alivio del dolor u otros síntomas molestos para el paciente. Generalmente, se admite que sólo un 5% de los pacientes afectados de enfermedad hematológica maligna presenta cuadros de dolor, mientras que en otros tipos de cáncer (pulmón, próstata y mama que cursan, con frecuencia, con metástasis ósea el porcentaje llega al 70-80% de los pacientes.

    It has long been recognized that there is a relationship between certain personality types and personality disorders (PD) and chronic nonmalignant pain (CP). The relationship, however, is far from understood and the physiological and psychological mechanisms that underlie it are unclear. Those who treat chronic pain face many challenges when dealing with individuals who have personality disorders and they often become frustrated when interacting with these patients. Patients with certain traits and personality disorders may continue to worry and ruminate about their symptoms long after the tissue pathology has resolved. Other individuals may overly rely on the clinician and assume a passive role in their treatment, thereby decreasing the likelihood for a positive outcome. Moreover, patients with personality disorders may be demanding (eg, borderline), self-absorbed (eg, narcissistic), or substance seeking (eg, antisocial, borderline). In an attempt to improve management of such patients, pain specialists have attempted to better understand the complex relationship between personality and chronic pain. In this article, we will review the predominant historical and current theories of pain and personality, discuss aspects of the gate-control theory of pain that may relate to personality, and discuss the diathesis-stress model of personality disorders in pain. Last, we will review studies of personality and personality disorders in chronic pain and their treatment implications. We conclude that, based on the underlying neurochemistry, there may be a direct or indirect link between PD and CP, but further prospective research, both on the biological and psychological relationship, should be conducted.

    A major limitation to current cancer therapies is the development of therapy-related side-effects and dose limiting complications. Moreover, a better understanding of the biology of cancer cells and the mechanisms of resistance to therapy is rapidly developing. The translation of advanced knowledge and discoveries achieved at the molecular level must be supported by advanced diagnostic, therapeutic and delivery technologies to translate these discoveries into useful tools that are essential in achieving progress in the war against cancer. Nanotechnology can play an essential role in this aspect providing a transforming technology that can translate the basic and clinical findings into novel diagnostic, therapeutic and preventive tools useful in different types of cancer. Hematological malignancies represent a specific class of cancer, which attracts special attention in the applications of nanotechnology for cancer diagnosis and treatment. The aim of the present review is to elucidate the emerging applications of nanotechnology in cancer management and describe the potentials of nanotechnology in changing the key fundamental aspects of hematological malignancy diagnosis, treatment and follow-up.

    2017-01-01

    Purpose The Accreditation Council for Graduate Medical Education (ACGME) has established communication as a core competency for physicians in training. However, data suggest that most pediatric residents perceive inadequate training in the delivery of bad news and the majority of former trainees in pediatric oncology received no formal training in the delivery of bad news during fellowship. The study examines communication training in ACGME accredited US pediatric hematology-oncology (PHO) fellowship programs. Methods An online survey was distributed to 315 PHO fellows in training via the American Society of Pediatric Hematology/Oncology (ASPHO) fellow email registry. Each fellow received an initial request to participate and 2 reminders, while participation was encouraged through a random incentive drawing. Results One hundred and ten fellows (35%) responded. Eighty percent of respondents perceived communication training to be important to fellow education, however only 32% reported receiving communication training (other than direct observation). The most common reported teaching method of fellowship communication training was formal lecture (42%). Twenty-three percent of respondents reported neither communication training nor frequent feedback on their communication skills from faculty observation. This same group was the least satisfied with their programs’ approach to teaching communication (P communication training in PHO fellowships despite ACGME requirements and fellows’ interest in this training. Didactic learning remains the most frequently described training method, yet educational theory identifies the limitation of didactic lectures alone. Communication training employing novel teaching methods and emphasizing communication challenges identified by fellows should be developed and evaluated. PMID:24039096

  5. Epigenetic mechanisms in the initiation of hematological malignancies

    Full Text Available Background: Cancer development is not restricted to the genetic changes, but also to epigenetic changes. Epigenetic processes are very important in the development of hematological malignancies. The main epigenetic alterations are aberrations in DNA methylation, post-translational modifications of histones, chromatin remodeling and microRNAs patterns, and these are associated with tumor genesis. All the various cellular pathways contributing to the neoplastic phenotype are affected by epigenetic genes in cancer. These pathways can be explored as biomarkers in clinical use for early detection of disease, malignancy classification and response to treatment with classical chemotherapy agents and epigenetic drugs. Materials and Method: A literature review was performed using PUBMED from 1985 to 2008. Cross referencing of discovered articles was also reviewed.Results: In chronic lymphocytic leukemia, regional hypermethylation of gene promoters leads to gene silencing. Many of these genes have tumor suppressor phenotypes. In myelodysplastic syndrome (MDS, CDKN2B (alias, P15, a cyclin-dependent kinase inhibitor that negatively regulates the cell cycle, has been shown to be hypermethylated in marrow stem (CD34+ cells in patients with MDS. At present both Vidaza and Decitabine (DNA methyltransferase inhibitors are approved for the treatment of MDS.Conclusion: Unlike mutations or deletions, DNA hypermethylation and histone deacetylation are potentially reversible by pharmacological inhibition, therefore those epigenetic changes have been recognized as promising novel therapeutic targets in hematopoietic malignances. In this review, we discussed molecular mechanisms of epigenetics, epigenetic changes in hematological malignancies and epigenetic based treatments

    The phosphoinositide 3-kinase pathway represents an important anticancer target because it has been implicated in cancer cell growth, survival, and motility. Recent studies show that PI3K may also play a role in the development of resistance to currently available therapies. In a broad range of cancers, various components of the phosphoinositide 3-kinase signaling axis are genetically modified, and the pathway can be activated through many different mechanisms. The frequency of genetic alterations in the phosphoinositide 3-kinase pathway, coupled with the impact in oncogenesis and disease progression, make this signaling axis an attractive target in anticancer therapy. A better understanding of the critical function of the phosphoinositide 3-kinase pathway in leukemias and lymphomas has led to the clinical evaluation of novel rationally designed inhibitors in this setting. Three main categories of phosphoinositide 3-kinase inhibitors have been developed so far: agents that target phosphoinositide 3-kinase and mammalian target of rapamycin (dual inhibitors), pan-phosphoinositide 3-kinase inhibitors that target all class I isoforms, and isoform-specific inhibitors that selectively target the α, -β, -γ, or -δ isoforms. Emerging data highlight the promise of phosphoinositide 3-kinase inhibitors in combination with other therapies for the treatment of patients with hematologic malignancies. Further evaluation of phosphoinositide 3-kinase inhibitors in first-line or subsequent regimens may improve clinical outcomes. This article reviews the role of phosphoinositide 3-kinase signaling in hematologic malignancies and the potential clinical utility of inhibitors that target this pathway. PMID:24425689

    The Samsung LABGEO(HC10) Hematology Analyzer (LABGEO(HC10)) is a recently developed automated hematology analyzer that uses impedance technologies. The analyzer provides 18 parameters including 3-part differential at a maximum rate of 80 samples per hour. To evaluate the performance of the LABGEO(HC10). We evaluated precision, linearity, carryover, and relationship for complete blood cell count parameters between the LABGEO(HC10) and the LH780 (Beckman Coulter Inc) in a university hospital in Korea according to the Clinical and Laboratory Standards Institute guidelines. Sample stability and differences due to the anticoagulant used (K₂EDTA versus K₃EDTA) were also evaluated. The LABGEO(HC10) showed linearity over a wide range and minimal carryover ( 0.92) except for mean corpuscular hemoglobin concentration. The bias estimated was acceptable for all parameters investigated except for monocyte count. Most parameters were stable until 24 hours both at room temperature and at 4°C. The difference by anticoagulant type was statistically insignificant for all parameters except for a few red cell parameters. The accurate results achievable and simplicity of operation make the unit recommendable for small to medium-sized laboratories.

    1987-02-01

    Radionuclide imaging studies of the bone marrow were carried out in 164 patients suffering from hematologic systemic disease. One third of 90 patients with Hodgkin lymphoma (HL) or Non Hodgkin lymphoma (NHL) displayed a pathological distribution pattern representing bone marrow expansion. In HL there were 17% accumulation defects caused by metastases in contrast to only 7% in NHL. Among 30 patients with chronic myelocytic leukemia bone marrow expansion was found in 60%, bone marrow displacement and aplasia 10%. Focal bone marrow defects were found in 3 patients. All patients with primary polycythemia rubra vera displayed a pathologic bone marrow distribution pattern as well as splenomegaly. All patients with acute myelocytic leukemia (AML) and one patient with an acute lymphatic leukemia (ALL) had a pathological distribution pattern with bone marrow expansion and displacement. Focal bone marrow defects were not seen. Multiple myeloma with bone marrow expansion was found in 6 of 12 patients and focal accumulation defects were found in 40%, the latter lesions being not visible or equivocal on skeletal imaging studies. Pathological changes in liver and spleen were found in a high percentage of the total collective. The results document the important clinical value of bone marrow scintigraphy among the hematologic diseases studied.

  9. Notch signaling: its roles and therapeutic potential in hematological malignancies.

    2016-05-17

    Notch is a highly conserved signaling system that allows neighboring cells to communicate, thereby controlling their differentiation, proliferation and apoptosis, with the outcome of its activation being highly dependent on signal strength and cell type. As such, there is growing evidence that disturbances in physiological Notch signaling contribute to cancer development and growth through various mechanisms. Notch was first reported to contribute to tumorigenesis in the early 90s, through identification of the involvement of the Notch1 gene in the chromosomal translocation t(7;9)(q34;q34.3), found in a small subset of T-cell acute lymphoblastic leukemia. Since then, Notch mutations and aberrant Notch signaling have been reported in numerous other precursor and mature hematological malignancies, of both myeloid and lymphoid origin, as well as many epithelial tumor types. Of note, Notch has been reported to have both oncogenic and tumor suppressor roles, dependent on the cancer cell type. In this review, we will first give a general description of the Notch signaling pathway, and its physiologic role in hematopoiesis. Next, we will review the role of aberrant Notch signaling in several hematological malignancies. Finally, we will discuss current and potential future therapeutic approaches targeting this pathway.

    Bryostatin-1 (bryo-1), a non-phorbol ester, is known to sensitize mammalian cells against certain chemotherapeutic drugs. We assessed its ability to modify radiation response of mammalian cells using Chinese hamster fibroblasts AA8 cells and human malignant glioma BMG-1 cells. In the malignant glioma BMG-1 cell line, bryo-1 pre-treatment significantly enhanced radiation-induced growth inhibition and cytogenetic damage, and further reduced the clonogenic cell survival as compared to cells irradiated at the clinically relevant dose of 2 Gy. PKCδ expression increased significantly when bryo-1 pre-treated BMG-1 glioma cells were irradiated at 2 Gy and induced prolonged ERK-1/2 activation associated with p21 overexpression. Silencing PKCδ resulted in inhibition of bryo-1-induced radiosensitization. In contrast, bryo-1 failed to alter radiosensitivity (cell survival; growth inhibition; cytogenetic damage) or activate ERK1/2 pathway in the AA8 fibroblasts despite PKCδ phosphorylation at its regulatory (Y155) domain, indicating alternate mechanisms in these non-malignant cells as compared to the glioma cells. This study suggests that bryo-1 may effectively enhance the radiosensitivity of malignant cells and warrants further in-depth investigations to evaluate its radiosensitizing potential in various cell types.

    Full Text Available Background: The most common types of non-malignant prostate diseases are benign prostatic hyperplasia (BPH and chronic prostatitis (CP. The aim of this study was to find out whether thermobalancing therapy with a physiotherapeutic device is effective for BPH and CP. Methods: During a 2.5-year period, 124 men with BPH over the age of 55 were investigated. Clinical parameters were tested twice: via the International Prostate Symptom Score (IPSS and via ultrasound measurement of prostate volume (PV and uroflowmetry maximum flow rate (Qmax, before and after six months of therapy. In 45 men with CP under the age of 55, the dynamics of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI were studied. Results: The results of the investigated index tests in men with BPH confirmed a decrease in IPSS (p < 0.001, a reduction in PV (p < 0.001, an increase in Qmax (p < 0.001, and an improvement of quality of life (QoL (p < 0.001. NIH-CPSI scores in men with CP indicated positive dynamics. Conclusions: The observed positive changes in IPSS, PV, and Qmax in men with BPH and the improvement in NIH-CPSI-QoL in patients with CP after using a physiotherapeutic device for six months as mono-therapy, support the view that thermobalancing therapy with the device can be recommended for these patients. Furthermore, the therapeutic device is free of side effects.

    In order to observe and ascertain the properties of a sub-group of T cells in the lymph node (LN) from seven patients who did not suffer from T cell lymphoproliferative disorders (T-LPDs), the expression levels of several pan-T markers were evaluated by multiparameter flow cytometry (FC) and the clonality of these T-cells was evaluated by both FC analysis and PCR assessment. It turned out that multiple pan-T-cell markers such as CD2, CD5 and CD7 were found to be lost in these T cells. The majority of them were positive for TCRαβ, only a minority of them being positive for TCRγδ. A subset of these T-cells were positive for CD4 or CD8 or dual-negative for CD4 and CD8. Oligoclonality was detected in one case by FC, while clonal TCR rearrangement was detected in three cases. Absence of multiple pan-T-cell markers could be found in benign T cells in LNs.

  19. Battling the hematological malignancies: the 200 years' war.

    The delineation of the hematological malignancies began near the end of the first third of the 19th century with the recognition of the similarity among cases with lymph node tumors and an enlarged spleen (Hodgkin's disease). Descriptions of chronic and acute leukemia and myeloma followed thereafter. In the first years of the 20th century the discovery of x-radiation permitted palliative orthovoltage radiation therapy of Hodgkin's disease. Following World War II, legitimate drug therapy for the hematological malignancies was introduced: nitrogen mustard, adrenocorticotropic hormone and cortisone acetate, and anti-folic acid derivatives, initially aminopterin. Today, about 14 classes of drugs (different mechanisms of action) and >50 individual agents are being used, with others under study. Several examples of agents targeting specific transcription factors or oncoproteins have been introduced. Despite remarkable progress, including the ability to cure acute leukemia in about 70% of children, cure several genetic variants of acute myelogenous leukemia in younger adults, cure some cases of lymphoma in children and younger adults, and induce prolonged remission in many affected persons, the majority of patients face an uncertain outcome and shortened life. Thus, we have much to do in the next several decades. The significant hurdles we must overcome include: the apparent infrequency of an exogenous cause that can be avoided, the exponential increase in incidence rates with age and the dramatic negative effect of aging on the results of treatment, the challenge of one trillion or more disseminated cancer cells among which are a smaller population of cancer stem cells, the profound genetic diversity of the hematological malignancies (apparently hundreds of unique genetic primary lesions), the redundant growth and survival pathways defining the cancer phenotype, the decreasing market for pharmaceutical companies as therapy becomes more specific (fewer target patients

    Genome editing technologies have advanced significantly over the past few years, providing a fast and effective tool to precisely manipulate the genome at specific locations. The three commonly used genome editing technologies are Zinc Finger Nucleases (ZFNs), Transcription Activator-Like Effector Nucleases (TALENs), and the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated Cas9 (CRISPR/Cas9) system. ZFNs and TALENs consist of endonucleases fused to a DNA-binding domain, while the CRISPR/Cas9 system uses guide RNAs to target the bacterial Cas9 endonuclease to the desired genomic location. The double-strand breaks made by these endonucleases are repaired in the cells either by non-homologous end joining, resulting in the introduction of insertions/deletions, or, if a repair template is provided, by homology directed repair. The ZFNs, TALENs and CRISPR/Cas9 systems take advantage of these repair mechanisms for targeted genome modification and have been successfully used to manipulate the genome in human cells. These genome editing tools can be used to investigate gene function, to discover new therapeutic targets, and to develop disease models. Moreover, these genome editing technologies have great potential in gene therapy. Here, we review the latest advances in the application of genome editing technology to the study and treatment of hematological disorders.

    The use of precise, rationally designed gene-editing nucleases allows for targeted genome and transcriptome modification, and at present, four major classes of nucleases are being employed: zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), meganucleases (MNs), and clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9. Each reagent shares the ability to recognize and bind a target sequence of DNA. Depending on the properties of the reagent, the DNA can be cleaved on one or both strands, or epigenetic changes can be mediated. These novel properties can impact hematological disease by allowing for: (1) direct modification of hematopoietic stem/progenitor cells (HSPCs), (2) gene alteration of hematopoietic lineage committed terminal effectors, (3) genome engineering in non-hematopoietic cells with reprogramming to a hematopoietic phenotype, and (4) transcriptome modulation for gene regulation, modeling, and discovery.

    2017-09-18

    Chimeric T cell receptors (CARs) combine extracellular antigen recognition domains and T cell activation components in single molecules. CAR gene transfer thereby allows to generate T cells with engineered specificities. The translational development of CAR-based T cell therapies is most advanced in B cell cancers where CAR-engineered T cells against the B lineage antigen CD19 have generated impressive results in early clinical trials. CARs are now also explored as tools to eliminate autoreactive B cell clones and to engineer T cells with immunosuppressive function for preventing pathological auto- or alloresponses. With ongoing intensive preclinical investigation and the advent of simplified manufacturing techniques, CAR T cells are expected to enter clinical investigation in a broader variety of hematological and solid cancers and in autoimmune diseases in the near future.

    Between 1956 and 1981, 306 splenectomies for hematologic diseases were performed at the UCLA Medical Center. Of these operations, more than 75% were performed for therapeutic reasons to control anemia, thrombocytopenia, neutropenia, or painful symptoms of splenomegaly. Of the 65 patients who had idiopathic thrombocytopenic purpura, 77% showed an excellent response, and of the 39 patients who had hereditary spherocytosis, 90% responded. Other diseases with predictably good response rates were autoimmune hemolytic anemias, Felty's syndrome, and hairy cell leukemia. Forty patients with Hodgkin's disease had splenectomies for diagnostic purposes the last 10 years. The overall morbidity and mortality were 24% and 6%, respectively, the most common complications being pneumonia, wound infections, and local postoperative bleeding, and the most common cause of death being sepsis. The review supports the thesis that in carefully selected patients, therapeutic splenectomy can have desirable palliative effects and that diagnostic splenectomy has a sufficiently low risk to warrant its consideration in patients with Hodgkin's disease.

    Full Text Available Abstract Metallothionein (MT was reported to be a potential negative regulator of apoptosis, and various reports have suggested that it may play roles in carcinogenesis and drug resistance, in at least a portion of cancer cells. The author summarizes the current understanding of the molecular functions of MT for tumor cell growth and drug resistance. These activities are regulated through intracellular metal ion modulation and free radical scavenging. Compared with analyses of solid tumors, few studies have analyzed the roles of MT in hematological malignancies. This review mainly describes the functions of MT in hematopoietic cells. Furthermore, through expression analyses of leukemias and lymphomas, the roles of MT in the biology of these diseases are particularly focused upon.

    Three cases of relapsing fever from southern Israel were diagnosed promptly thanks to vigilance of the hematology laboratory technicians. In this region of Israel, patients presenting with prolonged fever and leukopenia without localizing symptoms are generally suspected of having brucellosis or a rickettsial disease. Pediatric patients with prolonged fever, cytopenias, and negative aforementioned serologies are often hospitalized for further work-up. Because of the policy of performing a manual blood smear when results of the automated blood count demonstrate severe anemia and abnormal platelet and/or white blood cell counts, a diagnosis of tick-borne relapsing fever was confirmed and promptly relayed to the physician. This routine prevented unnecessary examinations and hospitalization days and provided important information to regional epidemiology and public health authorities.

    Full Text Available Myanmar is a country in southeast Asia in political, economic and healthcare transition. There are currently only two pediatric oncology centers serving a population of almost 19 million children. An estimated 85-92% of children with cancer are undiagnosed or not receiving treatment. Abandonment of treatment is as high as 60%. Although a number of chemotherapy agents are available, difficulties remain concerning treatment costs, quality control and the availability of supportive care. Radiotherapy services are also limited and not usually included in pediatric protocols. Healthcare professional training, improved diagnostics, strategies to tackle abandonment of treatment and the development of a parents′ support group are major priorities. Local and international partnerships including a recent partnership with world child cancer are essential in the interim to support the development of pediatric oncology and hematology in Myanmar. A unique opportunity exists to support the development of preventive, diagnostic, curative and palliative care for children′s cancer in Myanmar from the outset.

    Boyiadzis, Michael; Whiteside, Theresa L

    2015-09-01

    Exosomes are small (30-150 mm) vesicles secreted by all cell types and present in all body fluids. They are emerging as vehicles for delivery of membrane-tethered signaling molecules and membrane enclosed genes to target cells. Exosome-mediated information transfer allows for crosstalk of cells within the hematopoietic system and for interactions between hematopoietic cells and local or distant tissue cells. Exosomes carry physiological signals essential for health and participate in pathological processes, including malignant transformation. In hematologic malignancies, exosomes reprogram the bone marrow microenvironment, creating a niche for abnormal cells and favoring their expansion. The molecular and genetic mechanisms exosomes utilize to shuttle information between cells are currently being examined as are the potential roles exosomes play as biomarkers of disease or future therapeutic targets.

    Procedure-induced bleeding is a major complication after endoscopic intervention. The aim of this study was to investigate the risk of endoscopy-related bleeding in patients with chronic hematologic thrombocytopenia. We investigated endoscopy-related bleeding in 175 procedures performed on 108 patients with immune thrombocytopenic purpura or aplastic anemia. The outcomes were compared with those of 350 procedures on age-, sex-, and procedure-matched control subjects. Endoscopic interventions included low-risk procedures such as endoscopic biopsy and high-risk procedures including polypectomy, endoscopic resection, and endoscopic retrograde cholangiopancreatogram with sphincterotomy. Bleeding occurred in 17 (9.7%) procedures among the patients with thrombocytopenia. This rate was significantly higher than that in procedures on controls (3.1%, P = 0.003). About 60% of all bleeding events were observed within 24 h after the endoscopic procedure. Bleeding after endoscopic biopsy developed more frequently in the patient group than in the control group (7.1 vs. 0.7%; P Bleeding occurred after 20% of all high-risk procedures. The incidence of bleeding was significantly elevated in patients with a platelet count less than 50 × 10(3)/μl. Multivariate analysis revealed that high-risk procedures and low platelet count (less than 50 × 10(3)/μl) were significantly related to procedure-related bleeding. All bleeding events stopped spontaneously or were controlled with endoscopic hemostasis. Endoscopic procedure-related bleeding develops frequently in patients with chronic hematologic thrombocytopenia. Post-procedural bleeding should be observed carefully in these patients, especially when the platelet count is less than 50 × 10(3)/μl or high-risk endoscopic procedures are planned.

    To better prepare medical students to care for patients in today's changing health-care environment as they transition to continuing their education as residents, many US medical schools have been reviewing and modifying their curricula and are considering integration of newer adult learning techniques, including team-based learning, flipped classrooms, and other active learning approaches (Assoc Am Med Coll. 2014). Directors of hematology/oncology (H/O) courses requested an assessment of today's H/O education environment to help them respond to the ongoing changes in the education content and environment that will be necessary to meet this goal. Several recommendations for the improvement of cancer education resulted from American Association for Cancer Education's (ACCE's) "Cancer Education Survey II" including a call for medical schools to evaluate the effectiveness of current teaching methods in achieving cancer education objectives (Chamberlain et al. J Cancer Educ 7(2):105-114.2014). To understand the current environment and resources used in medical student preclinical H/O courses, an Internet-based, Survey Monkey®-formatted, questionnaire focusing on nine topic areas was distributed to 130 United States Hematology/Oncology Course Directors (HOCDs). HOCDs represent a diverse group of individuals who work in variably supportive environments and who are variably satisfied with their position. Several aspects of these courses remain relatively unchanged from previous assessments, including a predominance of traditional lectures, small group sessions, and examinations that are either written or computer-based. Newer technology, including web-based reproduction of lectures, virtual microscopes, and availability of additional web-based content has been introduced into these courses. A variety of learner evaluation and course assessment approaches are used. The ultimate effectiveness and impact of these changes needs to be determined.

    2003-11-01

    This study was undertaken to determine the impact of exposure to metal removal fluids (MRFs) on the respiratory health of exposed workers. The outcome measure selected was the rate of hospital admissions for nonmalignant respiratory disease episodes as determined from healthcare insurance claims data. A cohort of MRF-exposed employees was assembled from 11 manufacturing facilities where MRFs were extensively used in the manufacture of automotive engines, transmissions, and other machined parts. The MRF-exposed cohort included 20,434 employees of such facilities who worked at any time from 1993 through 1997. A non-MRF-exposed cohort was assembled from other employees of the same company during the same time period, but working in warehouse operations and other manufacturing facilities that did not use MRFs or any known respiratory sensitizing agents. The non-exposed cohort included 8681 employees. The crude hospital admission rate for the MRF-exposed cohort was 44 percent higher than that of the non-exposed cohort over the 5-year study period (6.67 vs. 4.62 per 1000 person years at risk, p risk of hospital admission increased with the level of MRF exposure in the population working in MRF plants. The industrial hygiene reconstruction found the levels of exposures of both cases and controls to be very low, with the vast majority of study subjects (more than 90%) having exposures of less than 0.5 mg/m(3). The case-control study did not find any association between increased levels of MRF exposure and risk of hospitalization. The study did document an elevated risk of hospitalization among a sizable population employed in manufacturing operations where MRFs are used.

    Full Text Available Abstract Background The lack of sufficient specificity and sensitivity among conventional cancer biomarkers, such as prostate specific antigen (PSA for prostate cancer has been widely recognized after several decades of clinical implications. Autoantibodies (autoAb among others are being extensively investigated as potential substitute markers, but remain elusive. One major obstacle is the lack of a sensitive and multiplex approach for quantifying autoAb against a large panel of clinically relevant tumor-associated antigens (TAA. Methods To circumvent preparation of phage lysates and purification of recombinant proteins, we identified B cell epitopes from a number of previously defined prostate cancer-associated antigens (PCAA. Peptide epitopes from cancer/testis antigen NY-ESO-1, XAGE-1b, SSX-2,4, as well as prostate cancer overexpressed antigen AMACR, p90 autoantigen, and LEDGF were then conjugated with seroMAP microspheres to allow multiplex measurement of autoAb present in serum samples. Moreover, simultaneous quantification of autoAb plus total PSA was achieved in one reaction, and termed the "A+PSA" assay. Results Peptide epitopes from the above 6 PCAA were identified and confirmed that autoAb against these peptide epitopes reacted specifically with the full-length protein. A pilot study was conducted with the A+PSA assay using pre-surgery sera from 131 biopsy-confirmed prostate cancer patients and 121 benign prostatic hyperplasia and/or prostatitis patients. A logistic regression-based A+PSA index was found to enhance sensitivities and specificities over PSA alone in distinguishing prostate cancer from nonmalignant cases. The A+PSA index also reduced false positive rate and improved the area under a receiver operating characteristic curve. Conclusions The A+PSA assay represents a novel platform that integrates autoAb signatures with a conventional cancer biomarker, which may aid in the diagnosis and prognosis of prostate cancer and others.

    Objective This systematic review aims to identify generic prognostic factors for disability and sick leave in subacute pain patients. Setting General practice and other primary care facilities. Participants Adults (>18 years) with a subacute (≤3-month) non-malignant pain condition. Eligibility criteria were cohort studies investigating the prediction of disability or long-term sick leave in adults with a subacute pain condition in a primary care setting. 19 studies were included, referring to a total of 6266 patients suffering from pain in the head, neck, back and shoulders. Primary and secondary outcome measures The primary outcome was long-term disability (>3 months) due to a pain condition. The secondary outcome was sick leave, defined as ‘absence from work’ or ‘return-to-work’. Results PubMed, EMBASE, CINAHL and PEDro databases were searched from 16 January 2003 to 16 January 2014. The quality of evidence was presented according to the GRADE WG recommendations. Several factors were found to be associated with disability at follow-up for at least two different pain symptoms. However, owing to insufficient studies, no generic risk factors for sick leave were identified. Conclusions Multiple site pain, high pain severity, older age, baseline disability and longer pain duration were identified as potential prognostic factors for disability across pain sites. There was limited evidence that anxiety and depression were associated with disability in patients with subacute pain, indicating that these factors may not play as large a role as expected in developing disability due to a pain condition. Quality of evidence was moderate, low or very low, implying that confidence in the results is limited. Large prospective prognostic factor studies are needed with sufficient study populations and transparent reporting of all factors examined. Trial registration number CRD42014008914. PMID:26739716

    Full Text Available Abstract Background Diseases associated with Epstein-Barr virus (EBV infections, such as infectious mononucleosis (IM, EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH and chronic active EBV infection (CAEBV are not rare in Chinese children. The association of type 1 or type 2 EBV and variants of the EBV BZLF1 promoter zone (Zp with these diseases is unclear. Results The objective of this study was to investigate the relationship between EBV genotypes (Zp variants and EBV type 1 and 2 and the clinical phenotypes of EBV-associated diseases in Chinese children. The Zp region was directly sequenced in 206 EBV-positive DNA samples from the blood of patients with IM, EBV-HLH, CAEBV, and healthy controls. Type 1 or type 2 EBV was examined by PCR for EBNA2 and EBNA3C subtypes. Four polymorphic Zp variants were identified: Zp-P, Zp-V3, Zp-P4 and Zp-V1, a new variant. The Zp-V3 variant was significantly associated with CAEBV (P ≤ 0.01. The frequency of co-infection with Zp variants was higher in patients with CAEBV and EBV-HLH, compared with IM and healthy controls, mostly as Zp-P+V3 co-infection. Type 1 EBV was predominant in all categories (81.3-95% and there was no significant difference in the frequency of the EBV types 1 and 2 in different categories (P > 0.05. Conclusions Type 1 EBV and BZLF1 Zp-P of EBV were the predominant genotypes in nonmalignant EBV associated diseases in Chinese children and Zp-V3 variant may correlates with the developing of severe EBV infection diseases, such as CAEBV and EBV-HLH.

    Full Text Available Abstract Background Massage is increasingly used to manage chronic pain but its benefit has not been clearly established. The aim of the study is to determine the effectiveness of a single session of nurse-administered massage for the short term relief of chronic non-malignant pain and anxiety. Methods A randomised controlled trial design was used, in which the patients were assigned to a massage or control group. The massage group received a 15 minute manual massage and the control group a 15 minute visit to talk about their pain. Adult patients attending a pain relief unit with a diagnosis of chronic pain whose pain was described as moderate or severe were eligible for the study. An observer blind to the patients' treatment group carried out assessments immediately before (baseline, after treatment and 1, 2, 3 and 4 hours later. Pain was assessed using 100 mm visual analogue scale and the McGill Pain Questionnaire. Pain Relief was assessed using a five point verbal rating scale. Anxiety was assessed with the Spielberger short form State-Trait Anxiety Inventory. Results 101 patients were randomised and evaluated, 50 in the massage and 51 in the control group. There were no statistically significant differences between the groups at baseline interview. Patients in the massage but not the control group had significantly less pain compared to baseline immediately after and one hour post treatment. 95% confidence interval for the difference in mean pain reduction at one hour post treatment between the massage and control groups is 5.47 mm to 24.70 mm. Patients in the massage but not the control group had a statistically significant reduction in anxiety compared to baseline immediately after and at 1 hour post treatment. Conclusion Massage is effective in the short term for chronic pain of moderate to severe intensity. Trial Registration [ISRCTN98406653

    To report on the post-tonsillectomy bleeding outcomes and factors associated with hemorrhage among children with pre- or post-operatively diagnosed bleeding disorders treated with an institutional protocol. Retrospective cohort study of patients with hematologic disorders who underwent tonsillectomy between 2003 and 2016 and were treated with perioperative desmopressin or factor replacement and/or aminocaproic acid. Postoperative outcomes were compared to controls matched for age, sex, and indication for surgery. Analysis of factors associated with hemorrhage was performed in patients with bleeding disorders using Mann-Whitney U or chi-squared tests. 45 patients with hematologic disorders met inclusion criteria. Platelet dysfunction, including von Willebrand Disease (vWD), was the most common diagnosis (77.8%). Most patients had a preoperative diagnosis of a bleeding disorder and received perioperative hematologic medications (86.7%). Compared to matched controls, patients with hematologic disorders experienced more postoperative bleeding (15.5%; 12 bleeds, 7 patients vs. 1.7%; 1 bleed, 1 patient, p = 0.05) and had longer postoperative stays (1.3 days vs. 0.4 days, p bleed were significantly more likely to have a factor deficiency (e.g. Hemophilia over vWD) and have a postoperative diagnosis (compared to preoperative diagnosis) for which they did not receive perioperative hematologic medication. Of patients with a postoperative bleed, all those diagnosed postoperatively required at least one surgical intervention to control bleeding compared to 33% of patients with a preoperative diagnosis. A history of post-surgical bleeding, male sex, age at surgery, and pharyngitis as surgical indication were not associated with higher hemorrhage rates in this group. This study suggests a clinically important magnitude of increased bleeding risk in patients with hematologic disease. This risk appears to decrease with the use of an institutional protocol consisting of

    Cardiopulmonary bypass (CPB)-induced thrombocytopenia and leukopenia is augmented after heparin reversal of protamine. Platelet-activating factor (PAF) might be implicated in these disorders. To evaluate the effects of PAF on the hematologic disorders and blood loss during and after CPB, patients were pretreated with BN 52021, a PAF receptor antagonist, or a placebo. BN 52021 (120 mg) (n = 13) or placebo (n = 15) were infused intravenously before vascular cannulation and before cross-clamp release. Platelet and leukocyte counts were assessed in venous blood before and after the first dose of BN 52021 or placebo, 2 min after the beginning of CPB (at the entry of the oxygenator), at the end of CPB, 1, 15, and 30 min after protamine infusion, and 6 and 24 h after CPB. The decrease in platelet and leukocyte counts were the same between groups during and after CPB and after protamine infusion. Bleeding times were not modified by the pretreatment of patients with BN 52021. During surgery, blood loss reached 1660 +/- 297 mL in the BN 52021 group and 1599 +/- 283 mL in the placebo group (P > 0.05). Forty-eight hours postoperatively, the chest tube outputs were not different between groups (1460 +/- 418 mL vs 1640 +/- 362 mL in the BN 52021 and placebo groups, respectively). This study shows that BN 52021 infusion did not change the hematologic variables studied. Moreover, a PAF antagonist pretreatment did not protect the patients against CPB- or protamine-induced hematologic changes.

  4. Breed-specific hematological phenotypes in the dog: a natural resource for the genetic dissection of hematological parameters in a mammalian species.

    Jennifer Lawrence

    Full Text Available Remarkably little has been published on hematological phenotypes of the domestic dog, the most polymorphic species on the planet. Information on the signalment and complete blood cell count of all dogs with normal red and white blood cell parameters judged by existing reference intervals was extracted from a veterinary database. Normal hematological profiles were available for 6046 dogs, 5447 of which also had machine platelet concentrations within the reference interval. Seventy-five pure breeds plus a mixed breed control group were represented by 10 or more dogs. All measured parameters except mean corpuscular hemoglobin concentration (MCHC varied with age. Concentrations of white blood cells (WBCs, neutrophils, monocytes, lymphocytes, eosinophils and platelets, but not red blood cell parameters, all varied with sex. Neutering status had an impact on hemoglobin concentration, mean corpuscular hemoglobin (MCH, MCHC, and concentrations of WBCs, neutrophils, monocytes, lymphocytes and platelets. Principal component analysis of hematological data revealed 37 pure breeds with distinctive phenotypes. Furthermore, all hematological parameters except MCHC showed significant differences between specific individual breeds and the mixed breed group. Twenty-nine breeds had distinctive phenotypes when assessed in this way, of which 19 had already been identified by principal component analysis. Tentative breed-specific reference intervals were generated for breeds with a distinctive phenotype identified by comparative analysis. This study represents the first large-scale analysis of hematological phenotypes in the dog and underlines the important potential of this species in the elucidation of genetic determinants of hematological traits, triangulating phenotype, breed and genetic predisposition.

    Baseline values and ranges for 10 hematologic and 32 plasma chemistry parameters were analyzed for 36 free-ranging Sonoran desert tortoises (Gopherus agassizzi) collected in Yavapai and La Paz Counties (Arizona, USA) from 1990 to 1995. Tortoises were radio tagged from 1990 to 1994, and attempts were made to recapture them three times a year. Tortoises were weighed, measured, and chemically immobilized to collect blood for hematology and blood chemistry assessments. Tortoise biochemistry differed (P < 0.01) between sites and sexes and among seasons and years. Normal reference ranges for hematologic and plasma biochemistry parameters were determined. Seasonal and annual differences in hematology and blood chemistry were related to rainfall patterns, forage availability, and physiological condition.

    The risk of melanoma and hematologic cancers in patients with psoriasis is controversial. We sought to assess the risk of melanoma and hematologic cancers in patients with psoriasis, and the association with different treatments. We used case-control and retrospective cohort designs to determine melanoma or hematologic cancer risk in patients with psoriasis. Risk with treatment type was assessed using Fisher exact test. Patients with psoriasis had 1.53 times greater risk of developing a malignancy compared with patients without psoriasis (P psoriasis and malignancy did not have significantly worse survival than patients without psoriasis. It is possible that patients developed malignancy subsequent to the follow-up time included in the study. Patients with psoriasis may experience an elevated risk of melanoma and hematologic cancers, compared with the general population. The risk is not increased by systemic or biologic psoriasis therapies. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    Anemia and other hematological abnormalities are common in patients with Sheehan's syndrome. The response of these abnormalities to replacement of thyroxine and glucocorticoids is not clear. The aim of the present study was to document the profile of hematological abnormalities and response to treatment in patients with Sheehan's syndrome. Forty patients of Sheehan's syndrome and an equal number of age and parity matched healthy controls were studied for prevalence of hematological abnormalities. Hemoglobin concentration, hematocrit, red cell, white cell and platelet count were significantly decreased in patients with Sheehan's syndrome compared to controls. Frequency of anemia, leucopenia, thrombocytopenia and pancytopenia was significantly higher in these patients compared to controls. After achieving euthyroid and eucortisol state, there was a complete recovery of these hematological abnormalities. We conclude that anemia and other cytopenias are common in patients with Sheehan's syndrome and replacement with thyroxine and glucocorticoids results in complete recovery of these abnormalities.

    The acronym WHIM refers to Warts, Hypogammaglobulinemia, Infections, and Myelokathexis. The latter refers to the retention of white cells in the marrow, which becomes hypercellular. We have found approximately 20 examples of WHIM syndrome in the literature under various designations; the first examples are Zuelzer [1964] and Krill et al. [1964]. Chronic noncyclic neutropenia and hypercellular bone marrow represent defective release of marrow cells into the peripheral stream (myelokathexis). The hypermature neutrophils are bizarre in form. Condensed nuclei connected by long, stringy filaments and vacuolated cytoplasm suggest apoptosis. Fever or other stress increases the release of neutrophils. Hypogammaglobulinemia is marked and associated with recurrent upper respiratory infections (sinusitis, tonsillitis, otitis media, pneumonia). Patients have numerous warts, some venereal, with resultant cervical and vulval premalignant dysplasia. We report on a kindred of 6 affected individuals in 3 generations with autosomal dominant WHIM syndrome. The sex ratio among reported patients and in our kindred is 17 female to 8 male. Because there had been no male-to-male transmssion, search of the entire X-chromosome including the pseudoautosomal area was carried out and no linkage was found. Recently, the propositus has had an unaffected daughter, confirming our finding that the gene is not X-linked. A genome-wide search is being carried out. Copyright 2000 Wiley-Liss, Inc.

    Blood eosinophilia (≥0.5 × 10(9) /l) may be an early sign of hematological malignancy. We investigated associations between levels of blood eosinophils and risks of hematological malignancies and mortality in order to provide clinically derived cut-offs for referral to specialist hematology care. From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 356,196 individuals with at least one differential cell count encompassing the eosinophil count during 2000-2007 and matched these laboratory data with Danish nationwide health registers. We used multivariable logistic regression to calculate odds ratios (ORs) for the 4-year incidences of hematological malignancies and mortality between the eosinophil counts and a reference count of 0.16 × 10(9) /l which was the median eosinophil count in our data. Risks of hematological malignancies and mortality increased above the median eosinophil count. At the 99th percentile, corresponding to an eosinophil count of 0.75 × 10(9) /l, risks of hematological malignancies were increased more than twofold with OR (95% C.I.) of 2.39 (1.91-2.99). Interestingly, risks reached a plateau around an eosinophil count of 1.0 × 10(9) /l. Risks also increased when the eosinophil count approached zero. Here, counts associated relatively more with acute myeloid leukemia and myelodysplastic syndromes whereas counts above 0.16 × 10(9) /l associated more with myeloproliferative neoplasms. Eosinophil counts associate with hematological malignancies and mortality even below the definition of eosinophilia. The observed plateau of risks around 1.0 × 10(9) /l is important for physicians encountering patients with eosinophilia since even mild-to-moderate eosinophilia according to traditional definitions confers maximally increased risks of subsequent/subclinical hematological malignancy.

    Delayed diagnosis of hematological malignancies in immunocompetent patients with fever of unknown origin (FUO) remains an exhausting challenge for non-hematologist physicians. This retrospective cohort study aimed to establish a scoring system, "bone marrow (BM) score", to identify FUO patients who require early bone marrow biopsy (BMB) to diagnose hematological disease. Two cohorts, comprising 85 (training) and 20 (validation) eligible immunocompetent patients, with FUOs diagnosed between January 1, 2006 and July 31, 2013, underwent BMBs and were enrolled in the study. Demographic, laboratory, imaging, diagnostic, and outcome data were collected and retrospectively analyzed. Factors associated with hematological etiologies diagnosed using BMBs in the training cohort were identified and scored according to the relative hazards. These were further validated using the validation cohort. For the training cohort, 29 of 85 (34.1%) patients had hematological etiologies diagnosed using BMB. Seven factors significantly predicted the diagnostic yield of hematological diseases in the BM and were scored, with the 6 points for leucoerythroblastic changes in peripheral blood smears, 5.5 for elevated ferritin level (>1000 ng/mL), 4 for splenomegaly, 2 for thrombocytopenia, 1.5 for each of elevated lactate dehydrogenase levels and anemia, and 1 for neutropenia. When the cut-off value of the scoring system was set to 6, its sensitivity and specificity to diagnose hematological diseases in the BM of immunocompetent FUO patients were 93% and 58%, respectively. For the validation cohort, 7 of 20 (35%) patients had hematological disease, and all had BM scores higher than the cut-off, with the sensitivity and specificity at 100% and 77%, respectively. As immunocompetent FUO patients with hematological disease have poor prognoses, the "BM score" is valuable for non-hematologist physicians to identify immunocompetent FUO patients requiring early BMB.

    Full Text Available Abstract Background Escherichia coli (E. coli is a pathogen of great concern in immunosuppressed patients.  While antimicrobial prophylactic therapy has become the standard, the emergence of resistant pathogens has some questioning its use.  This study describes our experience with E.coli as a pathogen in neutropenic patients with a hematologic malignancy, and addresses future directions of treatment for this patient population. Methods A retrospective chart review of 245 E.coli bacteremia patients at Moffitt Cancer Center from 05/18/02 – 05/15/12 was conducted. Patients were identified via microbiology laboratory computerized records. Results The included patients experienced clinically significant E.coli bacteremia resulting in a median hospital stay of 14.7 days.  Several patients developed severe sepsis requiring the use of pressor and ventilator therapy. Conclusions E.coli is a major pathogen in these patient populations resulting in extended hospital stays and specialized treatment to overcome their E.coli bacteremia. The data supports the use of fluoroquinolone prophylactic therapy, however, earlier detection and treatment of neutropenic infection is needed.

    There is large variation in the molecular genetics and clinical features of hemoglobinopathies in Iran. Studying structural variants of hemoglobin demonstrated that the β-chain variants of hemoglobin S and D-Punjab are more prevalent in the Fars (southwestern Iran) and Kermanshah (western Iran) provinces, respectively. Also, α-chain variants of Hb Q-Iran and Hb Setif are prevalent in western Iran. The molecular basis and clinical severity of thalassemias are extremely heterogenous among Iranians due to the presence of multiethnic groups in the country. β-Thalassemia is more prevalent in northern and southern Iran. Among 52 different β-thalassemia mutations that have been identified among Iranian populations, IVSII-1 G:A is the most frequent mutation in most parts of the country. The presence of IVS I-5 G:C mutation with high frequency in southeastern Iran might reflect gene flow from neighboring countries. A wide spectrum of α-thalassemia alleles has been detected among Iranians with -α(3.7 kb) as the most prevalent α-thalassemia mutation. The prevention program of thalassemia birth in Iran has reduced the birth rate of homozygous β-thalassemia since the implementation of the program in 1997. In this review genetic epidemiology, clinical and hematological aspects of hemoglobinopathies, and the prevention programs of β-thalassemia in Iran will be discussed.

    Cancer-related inflammation may play an important role in disease progression and patient outcome, and could be easily monitored through indirect parameters routinely evaluated at diagnosis. Here, we investigated if peripheral blood cells and the ratios of neutrophils to lymphocytes (NLR) and of lymphocytes to monocytes (LMR) as surrogate markers of cancer related inflammation are associated with disease progression and survival of melanoma patients at any stage of the disease. Records of 1,182 melanoma patients included in an Institutional tumor registry in the period 2000-2010, were reviewed. Among them, 584 patients with a cutaneous or unknown primary melanoma and available pre-operative blood tests were analyzed. Survival was estimated with the Kaplan-Meier method, and analyzed using Log-rank test, Cox regression and multivariate Cox proportional hazard models. We found that patients presenting with distant metastases had higher leukocytes, neutrophils and monocytes, and lower lymphocytes compared to Stage I-III patients. Furthermore, at a single-patient level, hematological profiles changed on disease progression from regional to distant metastatic, with significantly increased circulating leukocytes, neutrophils and monocytes, and decreased lymphocytes. Peripheral blood cell counts were not associated with survival of patients with a localized or regionally metastasized melanoma. Instead, in Stage IV patients, leukocytes (p = 0.001), neutrophils (p = 0.0002), monocytes (p = 0.002), NLR (p melanoma. © 2016 UICC.

    Blood samples were obtained from 30 coyotes (Canis latrans) captured in northern Wisconsin in conjunction with radio-telemetry studies. Samples were assayed for seven hematologic values, seven serum chemistries, serum albumin, globulin and total protein. Results are given with respect to sex and age and are compared with available data for captive wild and pen-raised coyotes. Leukocyte counts were greater for males than females and packed cell volumes were greater for adults than young, possibly due to differential response to capture and handling stress. Hemoglobin concentrations and calcium levels suggest differences in nutrition between pen-raised and wild coyotes. Sex and age differences in serum calcium for wild coyotes probably reflect nutritional differences between groups examined. Juvenile coyote serum alkaline phosphatase levels declined curvilinearly with age for coyotes less than one year old, suggesting a possible technique for separating juveniles and yearlings captured in autumn that are released for research purposes. Elevated glucose levels and leukocyte counts in wild coyotes may reflect greater handling stress than for pen-raised and captive coyotes. No significant sex or age effects were found for levels of serum urea nitrogen, total protein, cholesterol, and total bilirubin.

  12. Gab Adapter Proteins as Therapeutic Targets for Hematologic Disease

    Directory of Open Access Journals (Sweden)

    Sheetal Verma

    2012-01-01

    Full Text Available The Grb-2 associated binder (Gab family of scaffolding/adaptor/docking proteins is a group of three molecules with significant roles in cytokine receptor signaling. Gabs possess structural motifs for phosphorylation-dependent receptor recruitment, Grb2 binding, and activation of downstream signaling pathways through p85 and SHP-2. In addition, Gabs participate in hematopoiesis and regulation of immune response which can be aberrantly activated in cancer and inflammation. The multifunctionality of Gab adapters might suggest that they would be too difficult to consider as candidates for “targeted” therapy. However, the one drug/one target approach is giving way to the concept of one drug/multiple target approach since few cancers are addicted to a single signaling molecule for survival and combination drug therapies can be problematic. In this paper, we cover recent findings on Gab multi-functionality, binding partners, and their role in hematological malignancy and examine the concept of Gab-targeted therapy.

    Full Text Available Background: Ramadan fasting is an obligation for many Muslims around the world who abstain from eating and drinking for one month, which has different medical and physiological effects, such as reducing blood pressure, lipid profile, blood glucose, and body weight. It has also been hypothesized that Ramadan fasting may induce some changes in the hematologic parameters. Thus, we aimed to investigate the effect of Ramadan fasting on blood cell count (CBC, and erythrocyte sedimentation rate (ESR. Methods: In the present study, 59 adult healthy individuals, who had completed one month of Ramadan fasting were included. Fasting blood samples were analyzed for ESR, hemoglobin (Hb, hematocrit (Hct, white blood cell (WBC, platelet count (PLT, mean corpuscular Volume (MCV and mean platelet volume (MPV, one day before, on the second and last week of Ramadan and one month after Ramadan (phase I , II, III,  and IV, respectively. Results: 34 men and 25 women with an age range of 15 to 24 years participated in the study. Mean ESR increased significantly (except phase IV, in comparison phase III.

    DNA methylation has pivotal regulatory roles in mammalian development, retrotransposon silencing, genomic imprinting, and X-chromosome inactivation. Cancer cells display highly dysregulated DNA methylation profiles characterized by global hypomethylation in conjunction with hypermethylation of promoter CpG islands that presumably lead to genome instability and aberrant expression of tumor suppressor genes or oncogenes. The recent discovery of ten-eleven-translocation (TET) family dioxygenases that oxidize 5mC to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC) in DNA has led to profound progress in understanding the mechanism underlying DNA demethylation. Among the three TET genes, TET2 recurrently undergoes inactivating mutations in a wide range of myeloid and lymphoid malignancies. TET2 functions as a bona fide tumor suppressor particularly in the pathogenesis of myeloid malignancies resembling chronic myelomonocytic leukemia (CMML) and myelodysplastic syndromes (MDS) in human. Here we review diverse functions of TET proteins and the novel epigenetic marks that they generate in DNA methylation/demethylation dynamics and normal and malignant hematopoietic differentiation. The impact of TET2 inactivation in hematopoiesis and various mechanisms modulating the expression or activity of TET proteins are also discussed. Furthermore, we also present evidence that TET2 and TET3 collaborate to suppress aberrant hematopoiesis and hematopoietic transformation. A detailed understanding of the normal and pathological functions of TET proteins may provide new avenues to develop novel epigenetic therapies for treating hematological malignancies.

    Full Text Available Garlic commonly is consumed as medicine to prevent or heal illness or to maintain someone's health. Many societies prefer garlic (Allium sativum among other herbal remedies for cholesterol treatment. It consists of several types, and one of them is single bulb garlic used to treat hypertension. There has been, however, no published research reporting the toxicological properties of single bulb garlic. The purpose of this study was to determine subchronic toxic effects of single bulb garlic administered to mice using hematological parameters. The experiment parameters were hemoglobin and hematocrit levels, the number of erythrocytes and leukocytes. Male mice (Mus musculus strain Balb-C were treated with single bulb garlic extract for 28 days with dosage levels of 0% (N , 0.25% (P1 , 0.5% (P2 , 1% (P3 , and 2% (P4 . Single bulb garlic showed no effect on hemoglobin and hematocrit levels but increased the number of erythrocyte and leucocyte. We concluded that single bulb garlic did not cause subchronic toxic effects.

    Research published over the past year has documented the continued decline of Helicobacter pylori-related peptic ulcer disease and increased recognition of non-H. pylori, non-steroidal anti-inflammatory drugs ulcer disease--idiopathic ulcers. Despite reduced prevalence of uncomplicated PUD, rates of ulcer complications and associated mortality remain stubbornly high. The role of H. pylori in functional dyspepsia is unclear, with some authors considering H. pylori-associated nonulcer dyspepsia a distinct organic entity. There is increasing acceptance of an inverse relationship between H. pylori and gastroesophageal reflux disease (GERD), but little understanding of how GERD might be more common\\/severe in H. pylori-negative subjects. Research has focused on factors such as different H. pylori phenotypes, weight gain after H. pylori eradication, and effects on hormones such as ghrelin that control appetite.

  17. JAK2V617F drives Mcl-1 expression and sensitizes hematologic cell lines to dual inhibition of JAK2 and Bcl-xL.

    Jun Guo

    Full Text Available Constitutive activation of the Janus kinase (JAK/signal transducer and activator of transcription (STAT axis is fundamental to the molecular pathogenesis of a host of hematological disorders, including acute leukemias and myeloproliferative neoplasms (MPN. We demonstrate here that the major JAK2 mutation observed in these diseases (JAK2V617F enforces Mcl-1 transcription via STAT3 signaling. Targeting this lesion with JAK inhibitor I (JAKi-I attenuates STAT3 binding to the Mcl-1 promoter and suppresses Mcl-1 transcript and protein expression. The neutralization of Mcl-1 in JAK2V617F-harboring myelodyssplastic syndrome cell lines sensitizes them to apoptosis induced by the BH3-mimetic and Bcl-xL/Bcl-2 inhibitor, ABT-263. Moreover, simultaneously targeting JAK and Bcl-xL/-2 is synergistic in the presence of the JAK2V617F mutation. These findings suggest that JAK/Bcl-xL/-2 inhibitor combination therapy may have applicability in a range of hematological disorders characterized by activating JAK2 mutations.

    Full Text Available Background: To investigate the effects of moderate aerobic exercise on the hemoglobin, hematocrit, and red blood cell (RBC mass of women with rheumatoid arthritis (RA. Materials and Methods: This randomized clinical trial was conducted at the Specialized Clinic of Physical Medicine and Rehabilitation, Al-Zahra Hospital of Isfahan, during a 4-month period in 2014. We included patients with RA who did not have any malignancy and hematologic disorder. Two groups - one group receiving aerobic therapy along with medical therapy (N = 16 and the other group receiving medical therapy alone (N = 17 both for a period of 8 weeks. The levels of RBC mass, Hb, and HCT were measured before and after the intervention. The changes in these parameters were compared between the two study groups. Results: There was no significant difference between the two study groups regarding the baseline characteristics. The aerobic exercise resulted in increased RBC mass (P < 0.001, Hb (P < 0.001, and HCT (P < 0.001. However, those who received medical therapy alone did not experience any significant changes in these parameters. We found that the RBC mass (P = 0.581, Hb (P = 0.882, and HCT (P = 0.471 were comparable between the two study groups after 8 weeks of intervention. Conclusion: Although the aerobic exercise results in increased Hb, HCT, and RBC mass in patients with RA, the increase was not significant when compared to that in controls. Thus, the increase in the HB, HCT, and RBC could not be attributable to aerobic exercise.

    Full Text Available Objectives: To evaluate the health effects of benzene exposure among smoking subjects from a prolonged flaring incident that occurred at the British Petroleum (BP refinery in Texas City, USA. Material and Methods: The study included smoking subjects who had been exposed and unexposed to the benzene release. Using medical charts, clinical data including white blood cell (WBC counts, platelet counts, hemoglobin, hematocrit, blood urea nitrogen (BUN, creatinine, alkaline phosphatase (ALP, aspartate aminotransferase (AST, and alanine aminotransferase (ALT in the case of smoking subjects exposed to benzene was reviewed and analyzed. Results: A total of 791 tobacco smoking subjects (benzene-exposed: N = 733, unexposed: N = 58 were included. Benzene-exposed subjects had significantly higher levels of WBC (×103/μl counts (8±2.1 vs. 7.5±1.6, p = 0.003 and platelet (×103/μl counts (263.7±69.7 vs. 222.9±44.3, p = 0.000 as compared with the unexposed subjects. The mean hemoglobin, hematocrit, BUN, and creatinine levels did not differ significantly between the benzene-exposed and -unexposed smoking subjects. Serum levels of ALP (IU/l was significantly elevated in the benzene-exposed subjects compared with the unexposed subjects (84.5±16.9 vs. 73.8±15.9, p = 0.002. Similarly, benzene-exposed subjects had significantly higher levels of AST and ALT as compared with those unexposed subjects. Conclusions: Despite a smoking history, residents exposed to benzene from the prolonged BP flaring incident experienced significant alterations in hematological and hepatic functions indicating their vulnerability to the risk of developing hepatic or blood related disorders.

    Thalassemia is one of the most common hereditary disorders in the Mediterranean region and studies have shown that the prevalence of beta-thalassemia trait is high in the southern part of Turkey. Gaziantep is a city located near this region and, therefore, the authors investigated the prevalence and hematological characteristics of the beta-thalassemia traits in primary school students in Gaziantep. Sixty primary schools were selected from a list of all primary schools using a systematic sampling method. Data were collected by a face-to-face questionnaire. Osmotic fragility testing (OFT) using single-tube 0.36% NaCl solution was used for the screening of beta-thalassemia. Students who were positive in regard to OFT went through a series of testing, including a complete blood count, serum ferritin levels, serum iron, and hemoglobin electroforesis. Chi-square test was used in statistical analysis. Of the 2439 students enrolled to the study from the selected 60 classrooms, 1353 (55.5%) were male and 1086 (44.5%) were female. The OFT was positive in 115 (4.7%) of the participants. CEA and confirmatory HPLC results of the students who were positive OFT indicated that 70 (60.8%) had normal results, 33(28.7%) showed high HbA2 levels, 7 (6.1%) showed high HbA2 and HbF levels, 5(5.2%) showed high HbA2 and Fe-deficiency anemia, and none showed increased HbF levels. The overall prevalence of beta-thalassemia trait was 1.84%. No gender differentials and highest rates among the Kahramanmaras (3.5%) and Sanliurfa (1.7%) born students were the other significant findings of this study. Implementation of a routine carrier-screening program offering genetic counseling, prenatal diagnosis, and selective termination of affected fetuses would be a wise approach to eliminate this disease from the region.

    The three presentations in this session encompass clinical, pathophysiological and therapeutic aspects of hematologic diseases which impact most heavily on developing world countries. Dr. Victor Gordeuk discusses new insights regarding the multi-faceted pathogenesis of anemia in the complicated malaria occurring in Africa. He describes recent investigations indicating the possible contribution of immune dysregulation to this serious complication and the implications of these findings for disease management. Dr. Surapol Issaragrisil and colleagues describe epidemiologic and clinical characteristics of the thalassemic syndromes. In addition to being considered a major health problem in Southeast Asia, the migration throughout the world of people from this region has caused the disease to have global impact. A unique thalassemia variant, Hb Ebeta-thalassemia, with distinctive clinical features, has particular relevance for this demographic issue. Special focus will be reported regarding recent prenatal molecular screening methods in Thailand which have proven useful for early disease detection and disease control strategies. Dr. Raul Ribeiro describes a clinical model for providing effective treatment for a complex malignancy (childhood acute lymphoblastic leukemia) in countries with limited resources. With the multidisciplinary approach in Central American of the joint venture between St. Jude Children's Research Hospital International Outreach Program and indigenous health care personnel, major therapeutic advances for this disease have been achieved. Given the major demographic population shifts occurring worldwide, these illnesses also have important clinical implications globally. These contributions demonstrate that lessons learned within countries of disease prevalence aid our understanding and management of a number of disorders prominently seen in developed countries. They will show how effective partnerships between hematologists in more and less developed

In this study, we aimed to investigate the serum levels of vitamin B12 could represent the real tissue levels with con-sidering some hematological and biochemical parameters. 128 patients whose vitamin B12 levels have been detected to be low and their ages are ranged from 16 to 90, have been investigated. Fifty three of them were females. Complete blood counts, antiparietal antibody(APA, homocysteine levels, peripheral blood smear evaluations and findings of gastroduodenoscopy were assessed. Mean volume of erythrocytes has been found as 107 fl in patient group (group 1, in which vitamin B12 level has been detected lower than 60 pg/mL. Thehigher homocysteine values in 85% cases, neutrophil hyper-segmentation in 82%, atrophic gastritis in 53 % and APA positivity in 47 % of cases have been detected. The average of agehas been detected as 65 in this group. High level of homocysteine has been present in 44 % of cases and MCV has been 91 fl in group 2, in which the vitamin B12 levels are between 61–100 pg/ mL. In group ( group 3, in which vitamin levels are between 101 – 140 pg /mL,elevated homocysteine levels in 27 % cases and MCV as 89 fl have been detected. In group 4, in which vitamin levels are between 141–178 pg/mL, homocysteine elevation in 16 % of cases and MCV as

    Full Text Available In elderly people, anemia occurs with increasing frequency with each advancing decade and can be a harbinger of very serious health conditions, including gastrointestinal bleeding, gastric and duodenal ulcers, and cancer. Therefore, age-dependant changes in hematological parameters deserve special attention. Nonetheless, very few longitudinal studies of aging have focused on possible associations between basic anthropometric characteristics and hematological parameters in older people. Here, we present some evidence that body size can be associated with red blood cell count as well as some other selected hematological parameters in adults aged 45 to 70 years. Longitudinal data on anthropometric and hematological parameters have been obtained from physically healthy residents at the Regional Psychiatric Hospital for People with Mental Disorders in Cibórz, Lubuskie Province, Poland (142 individuals, including 68 men and 74 women. The residents who took psychoactive drugs were excluded from the study. To evaluate the studied relationships, three anthropometric traits were used and three dichotomous divisions of the study sample were made. The medians of body height, body weight, and body mass index at the age of 45 years were used to divide the sample into: shorter and taller, lighter and heavier, and slimmer and stouter individuals, respectively. Student’s t-test, Pearson’s correlation, and regression analysis were employed. The results of the present study suggest that the relationship between body size and red blood cell count is slightly more pronounced in men and its strength depends on age. However, the correlations between body size and red blood cell count proved to be weak in both sexes. With aging, the strength of the relation decreased gradually, which might have been caused by the aging-associated changes in the hematopoietic system, anemia, or was an artifact. Further studies are needed to elucidate the unclear association between

    Acquired uniparental disomy (aUPD) is a common and recurrent molecular event in human cancers that leads to homozygosity for tumor suppressor genes as well as oncogenes, while retaining the diploid chromosomal complement. Because of the lack of copy number change, aUPD is undetectable by comparative genome hybridization, so the magnitude of this genetic change was underappreciated in the past. 9p aUPD was first described in 2002 in patients with polycythemia vera (PV). Since then, systematic application of genomewide single-nucleotide polymorphism arrays has indicated that 9p aUPD is the most common chromosomal aberration in myeloproliferative neoplasms (MPNs), contributing to discovery of the PV-defining mutation JAK2V617F21. It was also found in other myeloid and lymphoid malignancies, though at a relatively lower frequency. By leading to JAK2V617F 23 homozygosity, 9p aUPD plays a causal role in the development of PV and is also associated with less favorable clinical outcomes. It is also possible that new targets other than JAK2V617F 25 are present within 9p aUPD that may contribute to diversity of PV outcome and phenotype. This review summarizes recent discoveries on 9p aUPD in hematologic malignancies and discusses possible underlying mechanisms and potential roles of 9p aUPD in the pathogenesis of PV, the relationship between 9p aUPD and JAK2V617F29, and possible new cancer-related targets within the 9p aUPD region.

  6. Technicon H*1 Hematology System: Optical Design Considerations

    1988-06-01

    The Technicon H*1 systemTM is a clinical laboratory flow cytometer which performs a complete hematology profile, providing quantitative information on the various types of cells in a blood sample. A light-scattering method, using a HeNe laser, determines in a single flow channel the red cell count, platelet count, and the distributions of red cell volume, red cell hemoglobin concentration, and platelet volume. To accomplish this the scattered light from each red cell in the sample is measured in real time at two angular intervals. The cell volume and the hemoglobin concentration within the cell are derived from these two measurements. Severe accuracy and precision specifications are placed on the medically important red cell count (RBC) and the mean red cell volume (MCV). From the point of view of optical system design, the dominant factor is the requirement that RBC and MCV have precision and accuracy of the order of 2%. Signal-to-noise and scattering-angle definition requirements dictated the choice of a HeNe laser light source. The optics includes an illumination system for producing a sharply defined, uniformly illuminated scattering region and a detection system which must accurately define the accepted scattering angles. In previous cytometric methods for determining MCV only a single quantity was measured for each cell. Such methods cannot disentangle the independent effects of cell size and hemoglobin concentration on the measurement, thus compromising MCV accuracy. The present double-angle scattering method overcomes this accuracy problem. The H*1 red cell method, the supporting optical design and data demonstrating that the use of this technique eliminates interference between the observed red cell indices are presented.

    Our purpose was to assess comparative female representation trends for trainees and full-time faculty in the academic radiation oncology and hematology oncology workforce of the United States over 3 decades. Simple linear regression models with year as the independent variable were used to determine changes in female percentage representation per year and associated 95% confidence intervals for trainees and full-time faculty in each specialty. Peak representation was 48.4% (801/1654) in 2013 for hematology oncology trainees, 39.0% (585/1499) in 2014 for hematology oncology full-time faculty, 34.8% (202/581) in 2007 for radiation oncology trainees, and 27.7% (439/1584) in 2015 for radiation oncology full-time faculty. Representation significantly increased for trainees and full-time faculty in both specialties at approximately 1% per year for hematology oncology trainees and full-time faculty and 0.3% per year for radiation oncology trainees and full-time faculty. Compared with radiation oncology, the rates were 3.84 and 2.94 times greater for hematology oncology trainees and full-time faculty, respectively. Despite increased female trainee and full-time faculty representation over time in the academic oncology physician workforce, radiation oncology is lagging behind hematology oncology, with trainees declining in recent years in radiation oncology; this suggests a de facto ceiling in female representation. Whether such issues as delayed or insufficient exposure, inadequate mentorship, or specialty competitiveness disparately affect female representation in radiation oncology compared to hematology oncology are underexplored and require continued investigation to ensure that the future oncologic physician workforce reflects the diversity of the population it serves.

    2014-01-01

    The aging of the U.S. population continues to highlight emerging issues in providing care generally for older adults and specifically for older adults with cancer. The majority of patients with cancer in the U.S. are currently 65 years of age or older; therefore, training and research in geriatrics and geriatric oncology are viewed to be integral in meeting the needs of this vulnerable population. Yet, the ways to develop and integrate best geriatrics training within the context of hematology/oncology fellowship remain unclear. Toward this end, the current study seeks to evaluate the prior and current geriatric experiences and perspectives of hematology/oncology fellows. To gain insight into these experiences, focus groups of hematology/oncology fellows were conducted. Emergent themes included: 1) perceived lack of formal geriatric oncology didactics among fellows; 2) a considerable amount of variability exists in pre-fellowship geriatric experiences; 3) shared desire to participate in a geriatric oncology-based clinic; 4) differences across training levels in confidence in managing older adults with cancer; and 5) identification of specific criteria on how best to approach older adults with cancer in a particular clinical scenario. The present findings will help guide future studies in evaluating geriatrics among hematology/oncology fellows across institutions. They will also have implications in the development of geriatrics curricula and competencies specific to hematology/oncology training. © 2013.

    Data on early biochemical and hematological responses to cobalamin therapy in vitamin B12-deficient patients are scarce. Therefore, we investigated whether cobalamin injections would include prompt biochemical and hematological responses in vitamin B12-deficient patients. Seven female patients (mean age: 69.4 years, range: 61-78) with a mean serum cobalamin level of 104 ± 38 pmol/l mean ± SD and 7 male patients (mean age: 67.0 years, range: 53-78) with a mean serum cobalamin level of 84 ± 40 (±SD) participated in the study. They were administered 1 mg i.m. cyanocobalamin per week for 3 weeks. Blood samples were collected before and 1, 3, 7, 14 and 21 days after cobalamin injection. The concentrations of plasma aminothiols and serum methylmalonic acid (MMA) were measured with high-performance liquid chromatography and gas chromatography/mass spectrometry, respectively, and hematological parameters were determined with a hematological analyzer. Already 1 day after intramuscular Cobalamin injections, the concentrations of serum vitamin B12 and plasma total cysteine were significantly increased while the concentrations of serum folate, plasma total homocysteine and serum MMA were decreased. Mean cell volume was also significantly decreased first after 14 days of therapy. Intramuscular cobalamin administration causes swift and significant changes in plasma aminothiols, whereas the first change in hematological parameters was detected only after 14 days.

    A growing body of literature has begun to underscore the importance of integrating family-based comprehensive psychological screening into standard medical care for children with oncology and hematology conditions. There are no known family-based measures designed to screen for clinically significant emotional and behavioral concerns in pediatric oncology and hematology patients. The aim of this study was to develop and evaluate the Family Symptom Inventory (FSI), a brief screener of patient and family member psychological symptoms. The FSI also screens for common comorbid physical symptoms (pain and sleep disturbance) and is designed for use at any point during treatment and follow-up. A total of 488 caregivers completed the FSI during regular hematology/oncology visits for 193 cancer, 219 sickle cell disease, and 76 hematology pediatric patients. Exploratory factor analysis, confirmatory factor analysis, and tests of reliability and preliminary validity were conducted. Exploratory factor analysis suggested a 34-item, 4-factor solution, which was confirmed in an independent sample using confirmatory factor analysis (factor loadings=0.49 to 0.88). The FSI demonstrated good internal reliability (α's=0.86 to 0.92) and good preliminary validity. Regular psychosocial screening throughout the course of treatment and follow-up may lead to improved quality of care for children with oncology and hematology conditions.

    Because changes in rat and dog hematological parameters according to storage conditions have been poorly documented, we sought to examine such changes. Blood analysis was performed using two hematology analyzers (ADVIA 2120i and Sysmex XN-V) after storage at room temperature and in cold storage for 5, 24, and 48 h, respectively. Interassay coefficients of variation for hematological parameters analyzed with the ADVIA 2120i and the XN-V showed similar. The levels of hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and platelet (PLT) showed significant variations with time in blood samples of rats and dogs. The leukocyte subpopulation showed high variation with storage conditions. The data for leukocyte differential counts obtained using the ADVIA 2120i, XN-V, and a manual differential counting procedure showed good agreement for neutrophils and lymphocyte counts, but monocytes, eosinophils, and basophils showed differences between the procedures. In conclusions, most rat and dog hematological parameters showed minimal changes; however, some showed high variation with storage time and temperature, especially PLT and leukocyte subpopulations. In conclusion, when performing hematological analysis in dogs and rats, it will be exactitude to analyze blood samples in fresh condition and at least within 24 h in the cold storage. PMID:28053618

One of these pathways, and the center of this review, is the phosphatidylinositol-3-kinase (PI3K pathway. The PI3K pathway seems to play an important role in the pathogenesis and survival advantage in hematologic malignancies, such as leukemia, lymphoma, and myeloma. The objectives of the present review, hence, are to describe the current knowledge on the PI3K pathway and its isoforms, and to summarize preclinical and clinical studies using PI3K inhibitors, focusing on the advances made in hematologic malignancies.

    The aim of the study was to relate seasonal hematology changes with the rest of physiological variations suffered by red deer, such as antler and biometrics cycle, and to assess the relationship between hematology and the effort performed in antler development. Blood samples were taken from 21 male red deer every 4 weeks during 18 months. Samples were analyzed for the main hematological parameters. Simultaneously, biometrics measurements were taken, such as antler length, body weight, body condition score, testicular diameter (TD), and thoracic and neck girth. All the blood cell types (erythrocytes, leukocytes, and platelets) showed seasonal variations, increasing as antler cleaning approached, as did hematocrit and hemoglobin. The final size of antlers was negatively related to leukocyte count, nonlymphoid leukocyte count, red cell distribution width, mean corpuscular hemoglobin, mean platelet volume, and TD, whereas it was positively related to body condition during antler growth. Huge seasonal variations in some hematological values have been found to be related to changes in antler and biometrics measurements. Since these variations are even greater than the caused by deer handling, they should be taken into account when evaluating hematology in deer populations.

    Background Reductions in transfusion requirements/improvements in hematologic parameters have been associated with iron chelation therapy in transfusion-dependent patients, including those with myelodysplastic syndromes; data on there reductions/improvements have been limited to case reports and small studies. Design and Methods To explore this observation in a large population of patients, we report a post-hoc analysis evaluating hematologic response to deferasirox in a cohort of iron-overloaded patients with myelodysplastic syndromes enrolled in the Evaluation of Patients’ Iron Chelation with Exjade® (EPIC) study using International Working Group 2006 criteria. Results Two-hundred and forty-seven, 100 and 50 patients without concomitant medication for myelodysplastic syndromes were eligible for analysis of erythroid, platelet and neutrophil responses, respectively. Erythroid, platelet and neutrophil responses were observed in 21.5% (53/247), 13.0% (13/100) and 22.0% (11/50) of the patients after a median of 109, 169 and 226 days, respectively. Median serum ferritin reductions were greater in hematologic responders compared with non-responders at end of study, although these differences were not statistically significant. A reduction in labile plasma iron to less than 0.4 μmol/L was observed from week 12 onwards; this change did not differ between hematologic responders and non-responders. Conclusions This analysis suggests that deferasirox treatment for up to 1 year could lead to improvement in hematologic parameters in some patients with myelodysplastic syndromes. PMID:22419577

    A subset of patients with familial platelet disorder with propensity to myeloid malignancy and germline RUNX1 mutation develops hematological malignancies, often myelodysplastic syndrome/acute myeloid leukemia, currently recognized in the 2016 WHO classification. Patients who develop hematologic malignancies are typically young, respond poorly to conventional therapy, and need allogeneic stem cell transplant from non-familial donors. Understanding the spectrum of bone marrow morphologic and genetic findings in these patients is critical to ensure diagnostic accuracy and develop criteria to recognize the onset of hematologic malignancies, particularly myelodysplastic syndrome. However, bone marrow features remain poorly characterized. To address this knowledge gap, we analyzed the clinicopathologic and genetic findings of 11 patients from 7 pedigrees. Of these, 6 patients did not develop hematologic malignancies over a 22-month follow-up period; 5 patients developed hematologic malignancies (3 acute myeloid leukemia; 2 myelodysplastic syndrome). All patients had thrombocytopenia at initial presentation. All 6 patients who did not develop hematologic malignancies showed baseline bone marrow abnormalities: low-for-age cellularity (n=4), dysmegakaryopoiesis (n=5), megakaryocytic hypoplasia/hyperplasia (n=5), and eosinophilia (n=4). Two patients had multiple immunophenotypic alterations in CD34-positive myeloblasts; 1 patient had clonal hematopoiesis. In contrast, patients who developed hematologic malignancies had additional cytopenia(s) (n=4), abnormal platelet granulation (n=5), bone marrow hypercellularity (n=4), dysplasia in ≥2 lineages including megakaryocytes (n=3) and acquired clonal genetic aberrations (n=5). In conclusion, our study demonstrated that specific bone marrow abnormalities and acquired genetic alterations may be harbingers of progression to hematological malignancies in patients with familial platelet disorder with germline RUNX1 mutation

    The link between the blood count and a systemic inflammatory response (SIR) is indisputable and well described. Pretreatment hematological parameters may predict the overall clinical outcomes in many types of cancer. Thus, this study aims to systematically evaluate the relationship between baseline blood count levels and treatment response in rectal cancer patients treated with neoadjuvant chemoradiotherapy. From 2009-2015, 173 patients with locally advanced rectal cancer were retrospectively enrolled in the study and analyzed. The baseline blood count was recorded in all patients 1 week before chemoradiation. Tumor response was evaluated through pathologic findings. Blood count levels which included RBC (red blood cells), Hb (hemoglobin), PLT (platelet count), neutrophil count, WBC (white blood cells), NLR (neutrophil-to-lymphocyte ratio), and PLR (platelet-to-lymphocyte ratio) were analyzed in relation to tumor downstaging, pCR (pathologic complete response), OS (overall survival), and DFS (disease-free survival). Hb levels were associated with a response in logistic regression analysis: pCR (p = 0.05; OR 1.04, 95 % CI 1.00-1.07); T downstaging (p = 0.006; OR 1.03, 95 % CI 1.01-1.05); N downstaging (p = 0.09; OR 1.02, 95 % CI 1.00-1.04); T or N downstaging (p = 0.007; OR 1.04, 95 % CI 1.01-1.07); T and N downstaging (p = 0.02; OR 1.02, 95 % CI 1.00-1.04); Hb and RBC were the most significant parameters influencing OS; PLT was a negative prognostic factor for OS and DFS (p = 0.008 for OS); an NLR value of 2.8 was associated with the greatest significance for OS (p = 0.03) and primary tumor downstaging (p = 0.02). Knowledge of pretreatment hematological parameters appears to be an important prognostic factor in patients with rectal carcinoma. (orig.)

    Full Text Available Most hematological patients suffer a significant venous damage related to different administrated intravenous therapy, being necessary to place central venous catheters (CVC. CVC is associated with various complications. The most common catheter-related complications are occlusion and infection. To avoid such of them, the development of protocols for insertion and care are needed, as well as recording and following up complications. To this end, we propose a cross-sectional carried out during 13 months whose main goal is to know the incidence of CVC- related complications (mainly occlusion and infection in hematological patients.Population included all the =14 ages patients admitted to different hematological units at Ramon y Cajal and Gregorio Marañón hospitals in Madrid and who signed informed consent. Socio-demographic, clinical characteristics and complications were entered into a log which included a pursuit of care protocol.

    Full Text Available The aim of this study was to examine the effects of resistance training on hematological blood markers in older individuals. Twenty-nine men and women participated to this study. Subjects were randomized in 2 groups: (1 control (n=13 and (2 resistance training (n=16. At baseline and after the intervention, subjects were submitted to a blood sample to determine their hematological profile (red blood cells, hemoglobin, hematocrit, platelets, leukocytes, neutrophils, lymphocytes, monocytes, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red cell distribution width. At baseline, no difference was observed between groups. Moreover, we found no significant difference after the intervention on any of these markers. A 6-month resistance program in healthy older individuals seems to have no beneficial nor deleterious effects on hematological blood parameters. However, resistance training was well tolerated and should be recommended for other health purposes. Further studies are needed to confirm these results in a large population.

    Hematologists/oncologists have a crucial responsibility to effectively communicate with patients. However, they have been criticized for ineffective communication with patients. To develop effective communication behaviors that meet the needs of patients and families, trainees need practice and feedback about their performance. Medical faculties frequently teach communication skills using simulation-based curricula; however, they often include only general communication skills, without tailored approaches for specialties. This study examined Hematology/Oncology trainees' qualitative perceptions about the value of and techniques used for simulations of specialty specific, essential conversations with patients and families, and debriefing sessions. Results demonstrate a highly effective curriculum and positive learner experiences. While most reports on this topic take place within major academic cancer centers, outcomes from a mid-sized Hematology/Oncology training program are unknown. The study confirms feasibility for implementing a simulation-based communications program in a mid-sized Hematology/Oncology program and describes simulation techniques that were effective.

    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.

    Full Text Available The aim of the study was to examine the structure of psychopathology and clinical features of depressive disorders in patients with brain oncopathology. Polymorphic mental disorders of various clinical content and severity in most cases not only are comorbid to oncological pathology of the brain, but most often are the first clinical signs of early tumors. The study was conducted using the following methods: clinical psychiatric, questionnaire Simptom Check List- 90 -Revised-SCL- 90 -R, Luscher test and mathematical processing methods. Sample included 175 patients with brain tumors with non-psychotic level of mental disorders. The peculiarities of mental disorders and psychopathological structure of nonpsychotic depressive disorders have been a clinical option of cancer debut in patients with brain tumors. We found that nonpsychotic depression is characterized by polymorphism and syndromal incompletion; this causes ambiguity of diagnoses interpretation on stages of diagnostic period. Features of depressive symptoms depending on the signs of malignancy / nonmalignancy of brain tumor were defined.

    α(0)-thalassemia is the most severe form of α-thalassemia alleles found among Southeast Asian and Chinese populations and can cause a fatal condition known as hemoglobin Bart's hydrops fetalis and hemoglobin H disease. In order to provide the molecular epidemiological characteristic of α(0)-thalassemia in northeast Thailand, a total of 12,525 blood specimens referred to our center at Khon Kaen University in northeast Thailand during October 2008 to January 2012 were studied. Hematological parameters were recorded and DNA deletions causing α(0)-thalassemia were examined by PCR related techniques. Among 12,525 samples examined, α(0)-thalassemia alleles were identified in 1,873 (15.0%) samples, including 1855 (14.8%) cases with Southeast Asian (--(SEA)) deletion and 18 cases (0.2%) with THAI deletion (--(THAI)). As many as twenty genotypes were encountered. Hb profiles and hematological parameters were comparatively presented. Data on prevalence, molecular features and phenotypic expression of α(0)-thalassemia should prove useful in a carrier screening and a prevention and control program of this common genetic disorder in the region.

    A retrospective study of blood samples from 95 osprey (Pandion haliaetus) nestlings from Scotland and England, collected opportunistically over a 10-yr period, was performed to determine hematologic and plasma biochemistry reference intervals. The age of the sampled nestlings was estimated to be between 4 and 8 wk. Ninety-five percent reference intervals were determined for all hematologic and biochemical variables using parametric and nonparametric methods as appropriate. No blood parasites were detected. This is the first published study providing baseline reference data for osprey nestlings, and it is hoped the data will be of use to wildlife veterinarians and biologists in assessing the health of this species.

    Biochemical and hematological parameters in blood of rainbow trout treated to various concentrations of propolis for 96 h were determined. Total leukocyte count and granulocytes values increased (ppropolis groups. There was a decrease in agranulocytes (ppropolis. MCV and MCH values (ppropolis caused an increase (plactate dehydrogenase, amylase and gamma glutamyltransferase. There was a decrease in the levels of aspartate aminotransferase and alkaline phosphatase. Hematological and biochemical protective effects of 0.01 g/L propolis were investigated. Dose-dependent effects of propolis on blood of fish can be favorable, opening new perspectives of investigation on their biological properties and utilization.

    Sheehan's syndrome presents with panhypopituitarism after childbirth, usually preceded by post partum hemorrhage. Hematological abnormalities like pancytopenia with hypocellular marrow in these patients are reported rarely. Though multiple hormone deficiencies may contribute to Pancytopenia in Sheehan's syndrome, complete recovery is observed after achieving eucortisolemic and euthyroid state. The predominant role of thyroxine or glucocorticoids in reversing pancytopenia in these patients has not been studied. We present the clinical, hormonal, hematological course and response to glucocorticoids in a patient of Sheehan's syndrome presenting with pancytopenia. Complete recovery of pancytopenia was observed after achieving eucortisolemic state thus concluding that gulcocorticoid replacement is sufficient to reverse pancytopenia in these patients.

    Background Myelodysplastic syndrome (MDS), a disorder of clonal hematopoiesis, is an important clinical entity, but most of the studies available are conducted among the Western population. Its etiological factors and clinicohematological profile in the Indian population are quite diverse. The information regarding its prognostic factors and cytogenetics is very scarce. Objectives (1) To assess the clinicohematological profile, cytogenetics, prognostic factors, and outcome of MDS and (2) to study its progression to acute myeloid leukemia (AML) in the selected patients over the study period. Methods A prospective observational study was performed with patients from Department of Medicine and Hematology, Government Medical College, Kozhikode, who were diagnosed with MDS within the study period (from 1 January 2014 to 31 July 2015). Secondary causes of dysplasia were excluded. In possible cases, the international prognostic scoring system was followed. These patients were followed up for an additional 6 months to assess the progression of MDS to AML based on symptoms, signs, hemogram, or repeat peripheral smear/bone marrow studies. Results Of the 60 patients, 73% were aged >60 years. Disease was common in males, with a male:female ratio of 7:3. Thirty-five percent of the patients were working in agricultural and allied fields and had pesticide exposure. Patients with prior radiation exposure had significant association with adverse outcome. Fatigue was the prominent symptom and was reported by 90% of the patients. Blasts were >5% in peripheral smear; bone marrow cytopenia and dysplasia at the time of diagnosis had significant association with risk of transforming to AML. Refractory anemia (RA), observed in 22 patients, was the most common type of MDS. Most of the patients with RA with excess blasts type-1 and RA with excess blasts type-2 transformed to AML, and the association was statistically significant.

    To determine if paraproteinemic keratopathy (PPK) in the setting of monoclonal gammopathy of undetermined significance (MGUS) causes distinct patterns of corneal opacification that can be distinguished from hereditary, immunologic, or inflammatory causes. A retrospective, interventional study of patients showed distinct bilateral opacity patterns of the cornea at the eye clinics of Hanau, Mainz, Helsinki, Marburg, and Berlin between 1993 and 2015. Data on patient characteristics and clinical features on ophthalmic examination were collected, and serum protein profiles were evaluated. A literature review and analysis of all published studies of MGUS with PPK is also presented. The largest group of patients diagnosed with MGUS-induced PPK is analyzed in this study. We studied 22 eyes of 11 patients (6 male, aged 43 to 65, mean age 54; 5 female, aged 49 to 76, mean age 61) with distinct corneal opacities and visual impairment who were first suspected of having hereditary, inflammatory, or immunologic corneal entities. Subsequently, serum protein electrophoresis revealed MGUS to be the cause of the PPK. Literature review revealed 72 patients with bilateral PPK (34 male, mean age 57; 38 female, mean age 58) in 51 studies of MGUS published from 1934 to 2015 and disclosed six additional corneal opacity patterns. This thesis shows that MGUS is not always an asymptomatic disorder, in contrast to the hematologic definition, which has no hint of PPK. The MGUS-induced PPK can mimic many other diseases of the anterior layer of the eye. A new clinical classification for PPK in MGUS is proposed.

    STAT3 protein phosphorylation is a frequent event in various hematologic malignancies and solid tumors. Acquired STAT3 mutations have been recently identified in 40% of patients with T-cell large granular lymphocytic leukemia, a rare T-cell disorder. In this study, we investigated the mutational status of STAT3 in a large series of patients with lymphoid and myeloid diseases. STAT3 mutations were identified in 1.6% (4 of 258) of patients with T-cell neoplasms, in 2.5% (2 of 79) of patients with diffuse large B-cell lymphoma but in no other B-cell lymphoma patients (0 of 104) or patients with myeloid malignancies (0 of 96). Functional in vitro assays indicated that the STAT3Y640F mutation leads to a constitutive phosphorylation of the protein. STA21, a STAT3 small molecule inhibitor, inhibited the proliferation of two distinct STAT3 mutated cell lines. Using a mouse bone marrow transplantation assay, we observed that STAT3Y640F expression leads to the development of myeloproliferative neoplasms with expansion of either myeloid cells or megakaryocytes. Together, these data indicate that the STAT3Y640F mutation leads to constitutive activation of STAT3, induces malignant hematopoiesis in vivo, and may represent a novel therapeutic target in some lymphoid malignancies.

    Full Text Available The knowledge of hematological values is useful in diagnosing various pathological and metabolic disorders, which can adversely affect reproductive performance of cows. The aim of this study was to investigate body condition score (BCS, body weight, calf weight, blood erythrocyte parameters and total and differential leukocyte count changes in dystocia-affected crossbred dairy cows. Values of mean corpuscular volume (MCV and neutrophil count were markedly increased (P<0.001 in the dystocia group compared to normal calving group. The levels of mean corpuscular haemoglobin concentration (MCHC and hematocrit in dystocia-affected cows were significantly lower (P<0.001 than normal control group. However, in cow suffering from dystocia, counts of the white blood cells (WBC, red blood cells (RBC, haemoglobin concentration, mean corpuscular haemoglobin (MCH, eosinophils, basophils, lymphocytes and monocytes were not different from the normal parturient group. In cows with dystocia, BCS, age and parity of dams did not show significant difference compared to normal parturition. However, body weight in cows with difficult calving was lower (P<0.05 than spontaneous calving cows. These results suggest that hematocrit, MCV, MCHC and neutrophil counts were significantly affected due to dystocia in cattle. BCS, age and parity of the cow had no affect on the occurrence of dystocia.

    The aim of the present study is to investigate whether or not pulsed electric field (PEF) affects some hematological parameters in rats. Sixteen healthy male Wistar rats weighting 150-200 g were used and were randomly divided into two groups. Exposure group (n = 8) was exposed to a PEF (10 kV m⁻¹ for 1 h d⁻¹) for 10 consecutive days. The control group rats (n = 8) were not exposed to PEF. The following hematological parameters were measured in both the groups: white blood cells (WBCs), red blood cells (RBCs), hemoglobin (Hb), hematocrit (Ht) and platelets (PLTs). Some of the hematological parameters under investigation were similar in both the groups. Exposure group, exposed for 1 h d⁻¹ during 10 consecutive days, induced a significant increase in the rates of WBC (p < 0.05), RBC (p < 0.05), Hb (p < 0.05), Ht (p < 0.05) and PLTs (p < 0.05) in blood when compared with control. These results suggest that PEFs affect the hematological parameters in rat. Results of the parameters are statistically significant.

    2016-01-01

    Full Text Available Angiogenesis plays an important role in progression of tumor with vascular endothelial growth factor (VEGF being key proangiogenic factor. It was intended to study angiogenesis in different hematological malignancies by quantifying expression of VEGF and MVD in bone marrow biopsy along with serum VEGF levels and observing its change following therapy. The study included 50 cases of hematological malignancies which were followed for one month after initial therapy along with 30 controls. All of them were subjected to immunostaining by anti-VEGF and factor VIII antibodies on bone marrow biopsy along with the measurement of serum VEGF levels. Significantly higher pretreatment VEGF scores, serum VEGF levels, and MVD were observed in cases as compared to controls (p<0.05. The highest VEGF score and serum VEGF were observed in chronic myeloid leukemia and maximum MVD in Non-Hodgkin’s Lymphoma. Significant decrease in serum VEGF levels after treatment was observed in all hematological malignancies except for AML. To conclude angiogenesis plays an important role in pathogenesis of all the hematological malignancies as reflected by increased VEGF expression and MVD in bone marrow biopsy along with increased serum VEGF level. The decrease in serum VEGF level after therapy further supports this view and also lays the importance of anti angiogenic therapy.

    This year we celebrate Blood's 70th year of publication. Created from the partnership of the book publisher Henry M. Stratton and the prominent hematologist Dr William Dameshek of Tufts School of Medicine, Blood has published many papers describing major advances in the science and clinical practice of hematology. Blood's founding antedated that of the American Society of Hematology (ASH) by more than 11 years and Stratton and Dameshek helped galvanize support for the creation of ASH. In this review, I place the birth of Blood in the context of the history of hematology before 1946, emphasizing the American experience from which it emerged, and focusing on research conducted during World War II. I also provide a few milestones along Blood's 70 years of publication, including: the growth in Blood's publications, the evolution of its appearance, the countries of submission of Blood papers, current subscriptions to Blood, and the evolution of topics reported in Blood's papers. The latter provides a snapshot of the evolution of hematology as a scientific and clinical discipline and the introduction of new technology to study blood and bone marrow. Detailed descriptions of the landmark discoveries reported in Blood will appear in later papers celebrating Blood's birthday authored by past Editors-in-Chief.

  7. HEMATOLOGICAL INDICES OF RAT ORGANISMS UNDER CONDITIONS OF OXIDATIVE STRESS AND LIPOSOMAL PREPARATION ACTION

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available The article deals with the results of search of the influence of developed complex liposomal drug on dynamics of hematological parameters of rat organisms under conditions of simulated oxidative stress caused by the use of carbon tetrachloride. Intramuscular injection of 50% tetrachloromethane to rats at a dose of 0.25 ml per 100 g of body weight causes antigenic load on the body and leads to disruption of physiologic level of hematological indices of experimental animal organisms. This indicates the number reduce of red blood cells, hemoglobin content, hemoglobin concentration in erythrocyte, increasing the number of leukocytes, mass of hemoglobin in erythrocyte and increased of color index. To normalize the hematological indices of rat organisms for the development of oxidative stress it is advisable to apply the liposomal drug that incorporates contains butafosfan, interferon, milk thistle and vitamins. When using liposomal drug to rats, under conditions of oxidative stress, the normalization of hematological indices comes in blood, namely on 14th day within physiological variables were indicators of the number of erythrocytes of hemoglobin content, white blood cell count and indices of red blood cells compared to controls, indicating a recovery of hematopoietic function of marrow.

    To study the hematology and serum biochemistry parameters of Indian spectacled cobra (Naja naja) and Indian rat snake (Ptyas mucosa) and to evaluate the differences in the same between captive and wild populations. Animals were categorized into four groups, viz., wild Indian spectacled cobra (n=10), wild Indian rat snakes (n=10), captive Indian spectacled cobra (n=10), and captive Indian rat snake (n=10). The snakes were restrained with restraint tubes, and 2 ml of blood was collected from either heart or ventral coccygeal vein. Hematological examinations were performed manually and serum biochemistry assays were performed on semi-automated clinical chemistry analyzer. The values of total erythrocyte count, packed cell volume, and hemoglobin were slightly low in captive spectacled cobras and captive rat snakes compared to wild ones, whereas total leukocyte count was found to be slightly high in wild spectacled cobras compared to captive ones. All the recorded values of biochemical and electrolyte analytes were found to be well within expected range for snakes except for total protein and chloride levels in both the species which was slightly above the expected range. The hematology and serum biochemistry intervals of the two most common Indian snakes are presented here. The data will be useful in routine health evaluations and aiding in better medical management of the species studied. Since this study is the first to report complete hematologic and blood biochemical ranges for the study species, observations made here can also be used as referral intervals for future use.

    2012-09-20

    We here investigate the occurrence of fluoride intake-associated alterations in patients with hematologic disease on triazol antifungal medication. Clinical, laboratory, and radiology data of overall 43 patients with hematologic malignancies taking voriconazole (n = 20), posaconazole (n = 8), and itraconazole (n = 4), and a hematologic patient control group (n = 11) are described. Bone pain and radiologic evidence of periostitis were exclusively observed in patients receiving long-term voriconazole. Cessation of treatment led to clinical improvement in all cases. In line with clinical evidence, fluoride serum concentration was elevated in patients receiving voriconazole (median, 156.5 μg/L; interquartile range, 96.8 μg/L; normal < 30 μg/L) but not in the other treatment groups (P < .001 for all comparisons vs voriconazole). We conclude that serum fluoride levels were elevated on average 5-fold above normal levels in hematologic patients receiving voriconazole. Clinically relevant skeletal disease was associated with renal insufficiency and above 10-fold elevated fluoride levels, and was reversible on termination of voriconazole treatment.

  14. Hematological Malignancies Escape from NK Cell Innate Immune Surveillance: Mechanisms and Therapeutic Implications

    Directory of Open Access Journals (Sweden)

    Laure Farnault

    2012-01-01

    Full Text Available Hematological malignancies treatment improved over the last years resulting in increased achievement of complete or partial remission, but unfortunately high relapse rates are still observed. Therefore, sustainment of long-term remission is crucial. Immune system has a key role in tumor surveillance. Natural killer (NK cells, at the frontier of innate and adaptive immune system, have a central role in tumor cells surveillance as demonstrated in the setting of allogenic stem cell transplantation. Nevertheless, tumor cells develop various mechanisms to escape from NK cells innate immune pressure. Abnormal NK cytolytic functions have been described in nearly all hematological malignancies. We present here various mechanisms involved in the escape of hematological malignancies from NK cells surveillance: NK cells quantitative deficiency and NK cell qualitative deficiency by increased inhibition signaling or decreased activating stimuli. A challenge of immunotherapy is to restore an efficient antitumor response. A combination of classical therapy plus immune modulation strategies will soon become a standard of care for hematological malignancies.

    We examined weights and hematologic profiles of gray wolf (Canis lupus) pups and the associated wolf density in the east-central Superior National Forest of northeastern Minnesota (USA) during 1970 to 1988. We collected weight and hematologic data from 117 pups (57 females, 60 males) during 1 September to 22 November each year. The wolf density (wolves/800 km2) trend was divided into three phases: high (72 +/- 7), 1970 to 1975; medium (44 +/- 2), 1976 to 1983; and low (27 +/- 2), 1984 to 1988. Wolf numbers declined (P = 0.0001) 39 and 63% from 1970 to 1975 to 1976 to 1983 and from 1970 to 1975 to 1984 to 1988, respectively. Weight was similar between male and female pups and did not vary as wolf density changed. Mean hemoglobin (P = 0.04), red (P = 0.0001) and white blood cells (P = 0.002), mean corpuscular volume, mean corpuscular hemoglobin concentration and mean corpuscular hemoglobin (P = 0.0001) did differ among the multi-annual phases of changing wolf density. Weight and hematologic data also were compared to values from captive wolf pups. The high, but declining wolf density was associated with macrocytic, normochromic anemia in wolf pups, whereas the lowest density coincided with a hypochromic anemia. Although hematologic values show promise for assessing wolf pup condition and wolf population status, they must be used cautiously until data are available from other populations.

    Hematological parameters are appraised routinely to determine overall human health and to diagnose and monitor certain diseases. In GWASs, more than 30 loci carrying common deoxyribonucleic acid (DNA) polymorphisms have been identified related to hematological traits. In this study, we investigated the contribution of ABO rs2073823 along with AQP1 rs1049305 and rs10244884 polymorphisms in hematological traits variation in a cohort of Iranian healthy individuals.Genomic DNA was extracted from peripheral blood of 168 healthy volunteer. Genotyping was performed by ARMS-PCR or PCR-RFLP and confirmed by DNA sequencing. Complete blood analyses were conducted for the participants. Significant association was observed between AQP1 rs1049305 and the hematological traits including hemoglobin, hematocrit, and platelet count (P = 0.012, 0.008, and 0.011, respectively). The AQP1 rs10244884 status was also significantly linked to hemoglobin and hematocrit levels in the study cohort (P = 0.015 and 0.041, respectively). Furthermore, ABO rs2073823 polymorphism was identified as a hemoglobin and hematocrit levels modifier (both with P = 0.004).AQP1 and ABO variants appear to predict hemoglobin and hematocrit levels but not other erythrocyte phenotype parameters including red blood cell counts and red blood cell indices.

    The 'Hariana' breed of cattle has been proved to be highly adaptable to harsh climatic conditions and resistant to common diseases prevalent in India. In this study, the normal reference values of hematological and serum proteins and other blood biochemical parameters were determined in the heifers of Hariana breed maintained at Instructional livestock farm complex, DUVASU, Mathura, India. A total of twenty four animals were used in this study. Blood was taken aseptically from all the animals and transported to laboratory for hematological and biochemical analysis. The hematological parameters (Hemoglobin, total erythrocyte count, total leukocyte count, packed cell volume) and biochemical parameters (Total protein, total albumin, albumin globulin ratio, urea, creatinine, calcium, phosphorous, calcium phosphorous ratio, AST, ALT) values were statistically analyzed, mean and standard deviations were calculated and set as reference values. This study reported hematological and serum biochemical values which could serve as baseline information for comparison in conditions of nutrient deficiency, physiological and health status of Hariana cattle heifers in India.

    Summary Background The purpose of the present study was to report and discuss the hematological and biochemical behavior of elite soccer players, in order to get more insight in the physiological characteristics of these sportsmen and to provide trainers and sports doctors with useful indicators. Methods Nineteen male soccer players volunteered to participate in this study. We followed the young elite soccer players during a competitive half season. Venous blood samples were collected between 9:00 and 10:00 a.m. after an overnight fast (10 h) at baseline, after 45 and 90 days and hematological and biochemical parameters were measured. Results Hemoglobin and hematocrit levels were significantly reduced over the observational period (psoccer training (psoccer players are characterized by significant changes in biochemical and hematological parameters over the half season, which are linked to training workload, as well as adaptation induced by the soccer training. Although the values of the measured parameters fell within the reference range, regular monitoring of the biochemical and hematological parameters is fundamental for the identification of a healthy status and related optimal performances by sport doctors and trainers and selection of a correct workload by trainers.

    Full Text Available Channa punctatus was exposed to four different concentrations of Rutin, Taraxerol and Apigenin. Changes in some hematological parameters of Channa punctatus were assessed to determine the influence of these compounds on test fish. Fish were exposed to sublethal concentrations (80% of LC50 of 24h of these compounds for one week. Control fish were also administered for one week. Thereafter, blood samples were obtained from the control and experimental fish. Blood was assayed for selected hematological parameters (hematocrit, hemoglobin, red blood cell count, white blood cell count total plasma protein and plasma glucose concentration. The derived hematological indices of mean corpuscular hemoglobin concentration (MCHC, mean corpuscular hemoglobin (MCH and mean corpuscular volume (MCV were calculated. Sublethal concentrations of these compounds caused a dose dependent decrease in hemoglobin values coupled with a decrease in hematocrit values and red blood cell counts are an obvious indication of anemia. The total white blood cell counts and the differential white blood cell counts were decreased except for the lymphocytes, where there was a slight increase. Plasma protein and glucose were also lower in exposed fish when compared with control. The hematological indices MCH, MCHC, MCV were also lowered. The result from this study reveals high mortality rate and deleterious consequences on the health of fish subjected to acute exposure of Rutin, Taraxerol and Apigenin and therefore, should not be used directly in aquaculture without having the proper knowledge.

    Many recent publications highlight the large role of the pivotal eukaryotic nuclear export protein exportin-1 (XPO1) in the oncogenesis of several malignancies, and there is emerging evidence that XPO1 inhibition is a key target against cancer. The clinical validation of the pharmacological inhibition of XPO1 was recently achieved with the development of the selective inhibitor of nuclear export compounds, displaying an interesting anti-tumor activity in patients with massive pre-treated hematological malignancies. Recent reports have shown molecular alterations in the gene encoding XPO1 and showed a mutation hotspot (E571K) in the following two hematological malignancies with similar phenotypes and natural histories: primary mediastinal diffuse large B cell lymphoma and classical Hodgkin's lymphoma. Emerging evidence suggests that the mutant XPO1 E571K plays a role in carcinogenesis, and this variant is quantifiable in tumor and plasma cell-free DNA of patients using highly sensitive molecular biology techniques, such as digital PCR and next-generation sequencing. Therefore, it was proposed that the XPO1 E571K variant may serve as a minimal residual disease tool in this setting. To clarify and summarize the recent findings on the role of XPO1 in B cell hematological malignancies, we conducted a literature search to present the major publications establishing the landscape of XPO1 molecular alterations, their impact on the XPO1 protein, their interest as biomarkers, and investigations into the development of new XPO1-targeted therapies in B cell hematological malignancies.

    Myelodysplastic syndromes (MDS) are clonal diseases of hematopoietic cells. The International Prognostic Scoring System (IPSS) is the risk scale most employed in MDS. Cyclosporin A (CsA) has been used in the treatment of cytopenias in MDS. To evaluate hematologic response and identify response predictive factors in adults with MDS treated with CsA. Patients with MDS diagnosed according World Health Organization (WHO) classification were recruited from January 1997 to June 2012. All patients were classified with IPSS, IPSS revised (IPSS-R),WHO Prognostic Scoring System (WPSS), and WPSS revised (WPSS-R) risk scales. Cyclosporin A was administered orally at a dose of 5 mg/kg/day. Hematologic response was evaluated following the International Working Group for MDS (2006 version) criteria. Inclusion criteria were met by 32 patients. Median age was 56.5 years, with a median follow-up of 3.1 years. Hematologic response was 56.2% and erythrocyte independence transfusion was found in 42.9% of patients. Age,hemoglobin level, and WPSS at diagnosis were independent predictive factors for CsA response. Survival was longer in responder than in nonresponder CsA patients (p=0.06). Cyclosporin A induced hematologic response in >50% of patients with MDS aged <57 years, with Hb<8 g/dl and low WPSS at diagnosis.

    Full Text Available Magellanic penguins (Spheniscus magellanicus routinely migrate from their breeding colonies to Southern Brazil often contracting diseases during this migration, notably avian malaria, which has been already reported in Brazil and throughout the world. Detection of Plasmodium spp. in blood smears is the routine diagnostic method of avian malaria, however it has a low sensitivity rate when compared to molecular methods. Considering the negative impact of avian malaria on penguins, the aim of this study was to detect the presence of Plasmodium spp. in Magellanic penguins using Polymerase Chain Reaction (PCR and by verifying clinical, hematological, and biochemical alterations in blood samples as well as to verify the likely prognosis in response to infection. Blood samples were obtained from 75 penguins to determine packed cell volume (PCV, red blood cell (RBC and white blood cell (WBC counts, mean corpuscular volume (MCV, uric acid, total protein, albumin, globulin and aspartate aminotransferase (AST activity levels. Whole blood samples were used for PCR assays. Plasmodium spp. was detected in 32.0% of the specimens using PCR and in 29.3% using microscopic analyses. Anorexia, diarrhea and neurological disorders were more frequent in penguins with malaria and a significant weight difference between infected and non-infected penguins was detected. PCV and MCV rates showed no significant difference. RBC and WBC counts were lower in animals with avian malaria and leukopenia was present in some penguins. Basophil and lymphocyte counts were lower in infected penguins along with high monocyte counts. There was no significant difference in AST activities between infected and non-infected animals. There was a significant increase in uric acid values, however a decrease in albumin values was observed in infected penguins. Based on this study, we concluded that Plasmodium spp. occurs in Magellanic penguins of rehabilitation centers in Southeastern Brazil

    Full Text Available Background: Administering extracorporeal membrane oxygenation (ECMO to critically ill patients with acute respiratory distress syndrome has substantially increased over the last decade, however administering ECMO to patients with hematologic malignancies may carry a particularly high risk. Here, we report the clinical outcomes of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO. Methods: We performed a retrospective review of the medical records of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO at the medical intensive care unit of a tertiary referral hospital between March 2010 and April 2015. Results: A total of 15 patients (9 men; median age 45 years with hematologic malignancies and severe acute respiratory failure received ECMO therapy during the study period. The median values of the Acute Physiology and Chronic Health Evaluation II score, Murray Lung Injury Score, and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score were 29, 3.3, and -2, respectively. Seven patients received venovenous ECMO, whereas 8 patients received venoarterial ECMO. The median ECMO duration was 2 days. Successful weaning of ECMO was achieved in 3 patients. Hemorrhage complications developed in 4 patients (1 pulmonary hemorrhage, 1 intracranial hemorrhage, and 2 cases of gastrointestinal bleeding. The longest period of patient survival was 59 days after ECMO initiation. No significant differences in survival were noted between venovenous and venoarterial ECMO groups (10.0 vs. 10.5 days; p = 0.56. Conclusions: Patients with hematologic malignancies and severe acute respiratory failure demonstrate poor outcomes after ECMO treatment. Careful and appropriate selection of candidates for ECMO in these patients is necessary.

    Hypercholesterolemia is an important risk factor linked to the alteration of blood hematology and clinical chemistry associated with the development and progression of atherosclerosis. Previous studies have demonstrated the safety and potential health benefits of Baccaurea angulata (BA) fruit. We hypothesized that the oral administration of BA fruit juice could ameliorate the alteration in the hematological and biochemical biomarkers of diet-induced hypercholesterolemic rabbits. The aim of this study was to investigate the effects of different doses of BA juice on the hematological and biochemical biomarkers in normo- and hypercholesterolemic rabbits. Thirty-five healthy adult New Zealand White rabbits were assigned to seven different groups for 90days of diet intervention. Four atherogenic groups were fed a 1% cholesterol diet and 0, 0.5, 1.0, and 1.5mL of BA juice per kg of rabbit daily. The other three normal groups were fed a commercial rabbit pellet diet and 0, 0.5, and 1.0mL of BA juice per kg of rabbit daily. Baseline and final blood samples after 90days of repeated administration BA juice were analyzed for hematological parameters while serum, aortic and hepatic lysates were analyzed for lipid profiles and other biochemical biomarkers. The alteration of the hemopoietic system, physiological changes in serum and tissues lipid profiles and other biochemicals resulting from the consumption of a high-cholesterol diet were significantly (Pjuice. Improvements of the biomarkers in rabbits were dose-dependent, markedly enhanced at the highest dose of juice (1.5mL/kg/day). The results suggest potential health benefits of the antioxidant-rich BA fruit juice against hypercholesterolemia-associated hematological and biochemical alterations in the rabbit.

    Standard hematology parameters were determined for 122 sloth bears (Melursus ursinus ursinus) at the Sur Sarovar Bird Sanctuary, Uttar Pradesh, India (27 degrees 0'N; 77 degrees 45'E), and the Bannerghatta Biological Park, Karnataka, India (12 degrees 48'N; 77 degrees 34'E) from March 2003 to July 2006. These two native sloth bear habitats have different climatic conditions and provided an opportunity to examine the effect of climate on the physiologic hematology values of these bears. We primarily analyzed the influence of age, sex, season, and body weight on the different hematology parameters. Several values were significantly different in sloth bear cubs (1 yr). The cubs had a lower erythrocyte count, hemoglobin concentration, packed cell volume (PCV), and mean cell hemoglobin (MCV) values when compared to adult and subadult bears. The cubs also had higher leukocyte counts, due to higher circulating neutrophils, as compared to adult and subadult bears. Within subadult and adult bears, we also identified a sexual dimorphic difference in leukocyte count in adult and subadult bears, wherein female bears had higher counts than males. This difference was the result of a significantly higher number of circulating neutrophils in female bears. Platelet counts were also higher in females as compared to males. On comparing different seasons, leukocyte counts were higher in winter as compared to the summer and monsoon seasons. When compared based on location, erythrocyte counts were higher in subadult and adult bears at Bannerghatta, which was at a higher altitude than Sur Sarovar. Within subadult and adult bears, we did not find any significant influence of age or body weight on the different hematologic parameters. In this study we have obtained mean hematologic values for sloth bears in their native habitat to serve as a reference for this species. This report will be useful to develop and evaluate health profiles of sloth bears under various ecological conditions.

  19. Genomic hallmarks of genes involved in chromosomal translocations in hematological cancer.

    Directory of Open Access Journals (Sweden)

    Mikhail Shugay

    Full Text Available Reciprocal chromosomal translocations (RCTs leading to the formation of fusion genes are important drivers of hematological cancers. Although the general requirements for breakage and fusion are fairly well understood, quantitative support for a general mechanism of RCT formation is still lacking. The aim of this paper is to analyze available high-throughput datasets with computational and robust statistical methods, in order to identify genomic hallmarks of translocation partner genes (TPGs. Our results show that fusion genes are generally overexpressed due to increased promoter activity of 5' TPGs and to more stable 3'-UTR regions of 3' TPGs. Furthermore, expression profiling of 5' TPGs and of interaction partners of 3' TPGs indicates that these features can help to explain tissue specificity of hematological translocations. Analysis of protein domains retained in fusion proteins shows that the co-occurrence of specific domain combinations is non-random and that distinct functional classes of fusion proteins tend to be associated with different components of the gene fusion network. This indicates that the configuration of fusion proteins plays an important role in determining which 5' and 3' TPGs will combine in specific fusion genes. It is generally accepted that chromosomal proximity in the nucleus can explain the specific pairing of 5' and 3' TPGS and the recurrence of hematological translocations. Using recently available data for chromosomal contact probabilities (Hi-C we show that TPGs are preferentially located in early replicated regions and occupy distinct clusters in the nucleus. However, our data suggest that, in general, nuclear position of TPGs in hematological cancers explains neither TPG pairing nor clinical frequency. Taken together, our results support a model in which genomic features related to regulation of expression and replication timing determine the set of candidate genes more likely to be translocated in

    Communication skills are a competency highlighted by the Accreditation Council on Graduate Medical Education; yet, little is known about the frequency with which trainees receive formal training or what programs are willing to invest. We sought to answer this question and designed a program to address identified barriers. We surveyed pediatric fellowship program directors from all disciplines and, separately, pediatric hematology/oncology fellowship program directors to determine current use of formal communication skills training. At our institution, we piloted a standardized patient (SP)-based communication skills training program for pediatric hematology/oncology fellows. Twenty-seven pediatric hematology/oncology program directors and 44 pediatric program directors participated in the survey, of which 56% and 48%, respectively, reported having an established, formal communication skills training course. Multiple barriers to implementation of a communication skills course were identified, most notably time and cost. In the pilot program, 13 pediatric hematology/oncology fellows have participated, and 9 have completed all 3 years of training. Precourse assessment demonstrated fellows had limited comfort in various areas of communication. Following course completion, there was a significant increase in self-reported comfort and/or skill level in such areas of communication, including discussing a new diagnosis (p =.0004), telling a patient they are going to die (p =.005), discussing recurrent disease (p communicating a poor prognosis (p =.002), or responding to anger (p ≤.001). We have designed a concise communication skills training program, which addresses identified barriers and can feasibly be implemented in pediatric hematology/oncology fellowship.

    Myeloproliferative neoplasms are characterized by a common stem cell-derived clonal proliferation, but are phenotypically diverse. JAK2 is mutated (V617F) in more than 90 % of patients with polycythemia vera (PV) and approximately 60 % of patients with essential thrombocythemia (ET) or primary myelofibrosis (PMF). Pulmonary arterial hypertension (PAH) is a major complication of several hematological disorders. Chronic myeloproliferative disorders associated with PAH have been included in group five for which the etiology is unclear and/or multifactorial. The aim of this study is to screen Egyptian Philadelphia negative JAK2 positive myeloproliferative neoplasm patients for the presence of PAH and its correlation with JAK2 allele burden. We also made a review for correlation of JAK2 allele with hematological parameters comparing our results to others. We enrolled 60 patients with Philadelphia negative myeloproliferative neoplasms. All patients enrolled in the study were subjected to laboratory and imaging workup in the form of CBC, liver, kidney profile, bone marrow examination, abdominal ultrasonography, and transthoracic echocardiography. Our results revealed that 7 patients out of 60 (11.67 %) had pulmonary arterial hypertension, 3 patients with PMF, 2 patients with PRV, and 2 patients with ET, and its correlation with JAK2 allele burden was not statistically significant. Correlation analysis between JAK2 V617F allele burden and other parameters revealed: statistical significant correlation with age, HB, HCT, PLT, UA, LDH, and splenic diameter but insignificant correlation with WBCs and PAH. Pulmonary arterial hypertension prevalence in our study was 11.67 % and no significant correlation with JAK 2 allele burden. Our study is the largest one up to our knowledge that studies the association between its prevalence and JAK2 burden.

    Results: Primary bone marrow disorders were the most common cause of macrocytosis (46%. The other causes in decreasing order of frequency were megaloblastic anaemia (38%, hemolytic anemia (6%, drug induced (5%, alcoholism and liver disease (4% and idiopathic thrombocytopenic purpura (1%. There was a significant difference in the mean values of MCV and serum LDH between megaloblastic and non and ndash; megaloblastic macrocytosis. When serum LDH >1345.2 IU/L or MCV>121fl (criterion values of ROC curve with reticulocyte count <2% was taken as criteria, the sensitivity was 92.1% and specificity was 93.5% for diagnosing megaloblastic anemia. Conclusions: Systematic evaluation of macrocytosis will help us to distinguish megaloblastic and non and ndash; megaloblastic macrocytosis. The blood and biochemical parameters especially CBC, RC, and serum LDH along with supporting clinical features help us in diagnosing megaloblastic anemia in a setup where vitamin and metabolite levels are difficult to obtain.

Primary or secondary antifungal prophylaxis is recommended for patients with hematological malignancies to reduce the risk of invasive fungal infection (IFI. This study retrospectively evaluated the efficacy and potential harm of administration of primary and secondary antifungal prophylaxis to patients with hematological malignancies at one hospital.Methods: All patients with hematological malignancies older than 14 years of age who had experienced at least one FN attack during chemotherapy while being treated at one hospital between November 2010 and November 2012 were retrospectively evaluated.Results: A total of 282 FN episodes in 126 consecutive patients were examined during a 2-year study period. The mean patient age was 51.73±14.4 years (range: 17–82 years, and 66 patients were male. Primary prophylaxis with posaconazole was administered to 13 patients and systemic antifungal treatment under induction or consolidation chemotherapy to seven patients. Of 26 patients who received secondary antifungal prophylaxis with either oral voriconazole (n=17 or posaconazole (n=6 during 46 FN episodes, systemic antifungal therapy was administered in 16 of 38 episodes and three of eight episodes, respectively. Secondary antifungal prophylaxis with caspofungin was found effective in treating six FN episodes in three patients who had experienced at least two persistent candidemia attacks. The mortality rates associated with IFI were 9% in the first year, 2% in the second year, and 6% overall. The mortality rates associated with candidemia

    Trimester specific reference ranges of hematological indices were described in several populations; however, comparable reports among Sudanese women with normal pregnancy are lacking. To evaluate trimester pattern of change and reference ranges of hematological profile among Sudanese women with normal pregnancy, we followed 143 women with singleton gestation since early pregnancy until the third trimester in Saad Abu-Alela Hospital, Khartoum, Sudan, during the period of January-December 2015. Obstetrics and medical history was gathered using questionnaire and hematological profile was investigated using hemo-analyser. The first, second and third trimester mean (SD) [5th-95th centile] of hematological profile were as follow: RBC counts 4.30 (0.36) [3.69-4.93], 4.35 (0.36) [3.69-4.93], 4.08 (0.44) [3.44-4.78] ×106/mm3; hemoglobin concentration 10.81 (1.22) [8.92-12.74], 10.62 (0.93) [9.00-12.10], 10.83 (1.13) [8.82-12.60] g/dL; hematocrit 35.38 (3.52) [30.12-40.30], 34.43 (2.51) [30.58-38.23], 35.17 (3.18) 29.66-40.04] %; WBC counts 7.69 (1.96) [4.36-11.20], 8.45 (1.97) [5.48-12.13], 8.36 (2.11) [5.00-11.96] ×103/mm3; platelet counts 278.02 (66.93) [182.6-418.0], 251.96 (64.17) [163.8-381.8], 238.36 (57.10) [150.4-346.2] ×103/mm3. The present study is the first to establish trimester specific, reference range for hematological profile among Sudanese women with normal pregnancy. The trimester reference range of RBC, WBC and platelets and other hematological indices are mostly parallel to international records. PMID:28243426

    Full Text Available O uso de agentes morfínicos para o controle da dor crônica não relacionada a câncer é controverso. Este estudo aferiu o alívio da dor e as mudanças nas atividades de 11 doentes com dor crônica não associada ao câncer, tratados pela infusão intratecal de fármacos morfínicos através de bombas implantáveis. A dor era neuropática em 5 doentes e miofascial em 6. A duração média da queixa álgica foi 5,3 anos. A média da intensidade da dor antes da infusão foi 8,6. Sete doentes apresentavam dor durante 6 ou mais horas por dia. Após o tratamento, a média de intensidade da dor reduziu-se para 3,9. Somente 1 doente manteve dor com duração superior a 6 horas. O tratamento melhorou o desempenho de 36,36% dos aspectos funcionais avaliados. O tempo médio de tratamento foi 19,6 meses. A infusão crônica de agentes morfínicos por via intratecal proporcionou alívio da dor, mas não melhorou a funcionalidade com a mesma magnitude.The use of opioids for treatment of non-malignant pain is controversial. The evaluation of pain relief and of the quality of life of 11 severely incapacitated chronic non-cancer pain patients treated with long term intrathecal infusion of opioids trought implantable pumps was performed. The mean duration of pain complaints was 5.3 years. The mean pain intensity was 8.6. In 7 patients, pain episodes lasted at least 6 hours daily. The mean duration of the therapy was 19.6 months. After the treatment the mean pain score became 3.9. In only 1 patient, the duration of pain episodes was still longer than 6 hours. Quality of life improved in 36.36% of the cases. The long term spinal opioids through implantable pumps for non-malignant pains results in pain relief but not necessarily improves the quality of life.

    Patients with type 1 Gaucher disease (GD1) have increased risk of developing myeloma, other hematological cancers, hepatocellular carcinoma, and other solid tumors. Patient awareness of the GD1-cancer association causes anxiety and fear. Little is known about cancer as a cause of death in GD1, especially in patients never treated with GD1-specific therapies. Consequently, the effect of treatment on cancer mortality in GD1 patients is difficult to evaluate. In this review, starting with a population of 184 GD1 cases never treated, we annotate and analyze the causes of death of 57 GD1 patients who died of cancer. The proportional mortality ratio (PMR) for all malignancies in patients with GD1 is 1.57 (p = 0.0002), but it is much higher for myeloma (PMR = 9.66) and other hematological cancers, hepatocellular carcinoma, and kidney cancer (PMR = ≍4). However, deaths from colorectal and pancreatic cancers were not more frequent than expected, and deaths from lung, breast, gynecological, and prostate cancer occurred less than anticipated. Herein, we discuss whether GD1 is truly a hereditary cancer syndrome and the problem of comorbidities and cancer risk assessment, and we speculate as to whether the variability in death by cancer type might be attributable to biochemical sequelae of tumor cell and macrophage/stromal cell GBA1 mutation affecting signals for metastasis, the process most closely associated with cancer mortality.

    Full Text Available Tempe is a potential source of protein for 250 million people in Indonesia. Indonesian soybean demand reached 2.2 million tons per year, and 1.3 million tons of which are used for tempe production. Approximately 70% of the soybeans are imported from different countries. To improve national food security, it is important to use local soybean as a raw material. Therefore, this study used Grobogan local soybean as raw material. The purpose of this study was to evaluate the impact of the consumption of tempe (from local soybean Grobogan in the long term, ie over a 90-day subchronic test using rats as a model. Parameters measured were serum biochemical profile, hematology, malonaldehyde (MDA, and superoxide dismutase (SOD in liver and kidney organs of rats. This research was conducted using three groups of rats which were fed tempe, boiled soybean, and casein as a source of protein in the ration. Data feed convertion efficiency showed that tempe of Grobogan soybean had a better protein quality than that of boiled soybean and casein. As compared to the groups of rats fed with boiled soybean and casein, the group fed with tempe had a higher HDL cholesterol, however no significant difference was observed in the hematological parameters, MDA and SOD in liver and kidney organs. This suggests consumption of tempe made from Grobogan soybean in the long term does not have a negative impact on health.

    Full Text Available Patients with common variable immunodeficiency (CVID develop autoimmune hematologic manifestations. We report a 14-year-old boy with Evans syndrome, who presented at the age of 11.5 years with autoimmune hemolysis and was successfully managed with corticosteroids. Initially, the serum immunoglobulins were within the low-normal range for age, but two years after presentation he definitely fulfilled the diagnostic criteria for CVID, despite a negative history for serious infections. DNA sequencing by PCR of the TNFSRF13B gene that encodes the TACI receptor disclosed the heterozygous mutation C104R that is found in approximately 10–15% of patients with CVID. Common variable immunodeficiency should be considered in the differential diagnosis of autoimmune hematologic manifestations, since its timely diagnosis may considerably affect clinical management and patient outcome.

    Full Text Available The number of patients with a previously diagnosed malignancy who need cardiac surgery is increasing. Patients with hematological malignancies represent only 0.38% of all patients undergoing cardiac surgery. The literature in this subset of patients is limited to only a few retrospective case series, with limited number of patients undergoing emergency cardiac surgery. We describe three cases with hematological malignancies namely chronic myelogenous leukemia, acute promyelocytic leukemia and chronic lymphocytic leukemia presenting for coronary artery bypass grafting (CABG. Two patients were taken up for emergency CABG in view of ongoing ischemia, one of them was on preoperative intra-aortic balloon pump support. No mortality was observed. Two patients needed transfusion of blood products which was guided by thromboelastography. One patient developed superficial sternal wound infection requiring antibiotic therapy.

    Crocodilians are important keystone species and indicators of environmental health. Much remains unknown, however regarding utility of field-collected crocodilian blood samples for ecologic assessments. Field sampling sites are also often distant to analysis centers, necessitating development of new techniques and panels of assays that will yield environmentally relevant data. Stability and viability of hematological and immunological indices have been of particular interest for linking ecosystem health to biomarkers in resident species. In this study, we investigated the effect of time at analysis post-blood sampling at 4 and 24 hr on a panel of potential biomarkers in alligator blood. Our results suggest alligator blood samples can be reliably evaluated for both hematologic and immunologic profile 24 hr after sampling.

    Baseline reference ranges of serum chemistry and hematology data can be important indicators for the status of both individuals or populations of wild animals that are affected by emerging pathogens, toxicants, or other causes of disease. Frequently, reference ranges for these values are not available for wildlife species or subspecies. We present hematologic and serum chemistry reference ranges for moose (Alces alces) adults, yearlings, and calves in Norway sampled from 1992-2000. Additionally, we demonstrated that both induction time and chase time were correlated with initial rectal temperature, although they were not significantly correlated with cortisol, aspartate aminotransferase, glucose, or creatine kinase. Overall, the reference ranges given here are similar to those given for American moose, with a few differences that can be attributed to environment, testing methodology, or subspecies or species status. This is the first report, to our knowledge, of reference ranges for moose in Norway.

    Full Text Available Leishmaniosis caused by Leishmania infantum is vector-born severe enzootic disease in dogs. It includes a wide spectrum of clinical symptoms, but the most characteristic are alterations in the hematopoetic system and renal failure. Also, infected animals could be asymptomatic, so the manifestation of L. infantum infection depends on many factors, including host’s immunological status. The aim of this survey was to find parameters related with hematopoetic and renal failure (hematology, biochemical parameters – urea, creatinine, serum proteins in symptomatic and asymptomatic dogs seropositive for canine leishmaniosis. Within the hematological parameters, we found signifi cant differences between symptomatic and asymptomatic dogs in the erythrogram and platelet count, but not in the leukogram. Significant differences between the two groups were found also for urea, creatinine, serum albumin and globulin, but not in serum total protein and A/G ratio. These findings indicate individual variability of the host’s response to infection with L. infantum.

    The survival gap between adolescents and young adults (AYAs) with hematological malignancies persists in many countries. To determine to what extent it does in Japan, we investigated survival and treatment regimens in 211 Japanese AYAs (15-29 years) in the Osaka Cancer Registry diagnosed during 2001-2005 with hematological malignancies, and compared adolescents (15-19 years) with young adults (20-29 years). AYAs with acute lymphoblastic leukemia (ALL) had a poor 5-year survival (44%), particularly young adults (29% vs. 64% in adolescents, p = 0.01). Additional investigation for patients with ALL revealed that only 19% of young adults were treated with pediatric treatment regimens compared with 45% of adolescents (p = 0.05). Our data indicate that we need to focus on young adults with ALL and to consider establishing appropriate cancer care system and guidelines for them in Japan.

    2016-01-01

    To date, two kinds of Granulocyte Colony-Stimulating Factors (G-CSF) have been approved for autologous peripheral blood hematopoietic stem cell (PBSCs) mobilization and posttransplant hematologic recovery after high-dose chemotherapy: filgrastim (originator and biosimilar) and lenograstim. Biosimilar filgrastim has been approved on the basis of comparable efficacy and safety in clinical studies where it has been used as chemotherapy-induced febrile neutropenia prophylaxis, but no specific pre-registration studies have been published in the transplant setting. Hence, there is still general skepticism about the role of biosimilar G-CSFs in this setting of patients. This review of biochemical, pre-clinical and clinical data suggests significant comparability of biosimilar filgrastim with both originator filgrastim and lenograstim in autologous PBSCs mobilization and post-autograft hematologic recovery.

    Over the last two decades, since the discovery of Drosophila mutants in 1995, much effort has been made to understand Aurora kinase biology. Three mammalian subtypes have been identified thus far which include the Aurora A, B and C kinases. These regulatory proteins specifically work at the cytoskeleton and chromosomal structures between the kinetochores and have vital functions in the early phases of the mitotic cell cycle. Today, there are multiple phase I and phase II clinical trials as well as numerous preclinical studies taking place looking at Aurora kinase inhibitors in both hematologic and solid malignancies. This review focuses on the preclinical and clinical development of Aurora kinase inhibitors in hematological malignancy and discusses their therapeutic potential. PMID:26622997

    Full Text Available Columnaris disease is one of the main causes of mortality in tilapia rearing and is responsible for large economic losses worldwide. Hematology is a tool that makes it possible to study organisms' physiological responses to pathogens. It may assist in making diagnoses and prognoses on diseases in fish populations. The hematological variables of nile tilapia were studied in specimens with a clinical diagnosis of columnaris disease and in specimens that were disease-free. The total erythrocyte count, hemoglobin rate, hematocrit percentage, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC, mean corpuscular volume (MCV, organic defense blood cell percentages (leukocytes and thrombocytes and hepatosomatic and splenosomatic index were determined. The results showed that there were changes in the erythrocytic series and in organic defense blood cells, in the fish infected with the bacterium, with reductions in erythrocytic variables and significant increases in the numbers of circulating lymphocytes and neutrophils.

    The aim of this study was to compare hematological, some biochemical parameters, and serum trace element concentrations in horses with or without pica. Fifteen horses with pica (group I) and another 15 healthy horses without pica (group II) were used. The hematological parameters were not changed between the two groups. In group I, hemoglobin values were lower than those of group II. However, the difference in hemoglobin values between the two groups was not significant (P > 0.05). Serum iron and copper concentrations and the copper/zinc ratio were lower in group I than those of group II (P  0.05). It was concluded that serum iron and copper deficiency may play an important role for the etiology of pica in horses. Prophylactic use of iron and copper supplements in horses may be beneficial to prevent pica.

    Full Text Available This study investigated the hematological parameters of the tropical estuarine fish Centropomus parallelus and their use as a non-destructive biomarker for aquatic pollution. Individuals were collected, in summer and winter, at two estuaries, Cananéia (CAN and São Vicente (SVE, and blood was extracted by caudal puncture. The evaluated parameters were hematocrit (Ht, red blood cells (RBC, Mean Corpuscular Volume (MCV, and the leukocyte (WBC and thrombocyte counts. Fishes from CAN showed higher values of absolute number of thrombocytes in the summer. The fishes from SVE presented lower values of Ht and MCV in winter. Comparing the hematological parameters of fishes from these two sites, Ht, MCV, WBC and RBC were higher in fishes from SVE in the summer, whereas during the winter, Ht and thrombocytes were higher in animals from SVE. The results allow attributing the changes in the blood of fishes to seasonality and the presence of contaminants.

    Hematological and serum chemical constituents of blood were determined for 12 species, including 7 endangered species, of cranes, geese, raptors, and quail in captivity at the Patuxent Wildlife Research Center. Means, standard deviations, analysis of variance by species and sex, and a series of multiple comparisons of means were derived for each parameter investigated. Differences among some species means were observed in all blood parameters except gamma-glutamyl transpeptidase. Although sampled during the reproductively quiescent period, an influence of sex was noted in red blood cell count, hemoglobin, albumin, glucose, cholesterol, serum glutamic oxaloacetic transaminase, Ca, and P. Our data and values reported in literature indicate that most hematological parameters vary among species and, in some cases, according to methods used to determine them. Therefore, baseline data for captive and wild birds should be established by using standard methods, and should be made available to aid others for use in assessing physiological and pathological conditions of these species.

    Neonatal thrombocytopenia is a common clinical problem and may be a result of maternal and/or fetal conditions. We present a young patient with thrombocytopenia as a result of neonatal lupus, a passively acquired autoimmune disease. The diagnosis was suspected on the basis of the presence of a facial rash. This case highlights the characteristic eruption of neonatal lupus and an underappreciated cause of neonatal thrombocytopenia for the pediatric hematologist. We also review the hematological complications of neonatal lupus.

    Full Text Available Background The risk of getting influenza and pneumococcal disease is higher in cancer patients and serum antibody levels tend to be lower in patients with hematological malignancy. Objective To asses flu and pneumococcal vaccinations efficacy, effectiveness and safety in onco-hematological patients. Methods Two systematic reviews and possible meta-analysis were conducted to summarize the results of all primary study in scientific literature about flu and pneumococcal vaccine in onco-hematological patients. Literature searches were performed using Pub-Med and Scopus databases. StatsDirect 2.8.0 was used for the analysis. Results 23 and 26 studies were collected respectively for flu and pneumococcal vaccinations. Protection rate of booster dose was 30% (95% CI = 6.2- 61% for H1N1. Pooled prevalence protection rate of H3N2 and B was available for meta-analysis only for first dose, 42.6% (95% CI = 23.2 – 63.3 % and 39.6 % (95% CI = 26%- 54.1% for H3N2 and B, respectively. Response rate of booster dose resulted 35% (95% CI = 19.7-51.2% for H1N1, 23% (95% CI = 16.6-31.5% for H3N2, 29% (95% CI = 21.3- 37% for B. Conclusion Despite low rate of response, flu and pneumococcal vaccines are worthwhile for patients with hematological malignancies. Patients undergoing chemotherapy in particular rituximab, splenectomy, transplant recipient had lower and impaired response. No serious adverse events were reported for both vaccines.

    Full Text Available Aim: To study the hematology and serum biochemistry parameters of Indian spectacled cobra (Naja naja and Indian rat snake (Ptyas mucosa and to evaluate the differences in the same between captive and wild populations. Materials and Methods: Animals were categorized into four groups, viz., wild Indian spectacled cobra (n=10, wild Indian rat snakes (n=10, captive Indian spectacled cobra (n=10, and captive Indian rat snake (n=10. The snakes were restrained with restraint tubes, and 2 ml of blood was collected from either heart or ventral coccygeal vein. Hematological examinations were performed manually and serum biochemistry assays were performed on semi-automated clinical chemistry analyzer. Results: The values of total erythrocyte count, packed cell volume, and hemoglobin were slightly low in captive spectacled cobras and captive rat snakes compared to wild ones, whereas total leukocyte count was found to be slightly high in wild spectacled cobras compared to captive ones. All the recorded values of biochemical and electrolyte analytes were found to be well within expected range for snakes except for total protein and chloride levels in both the species which was slightly above the expected range. Conclusion: The hematology and serum biochemistry intervals of the two most common Indian snakes are presented here. The data will be useful in routine health evaluations and aiding in better medical management of the species studied. Since this study is the first to report complete hematologic and blood biochemical ranges for the study species, observations made here can also be used as referral intervals for future use.

A prompt identification of infection and empirical antibiotic therapy can prolong survival. This paper reviews the guidelines about febrile neutropenia in the setting of hematologic malignancies, providing an overview of the definition of fever and neutropenia, and categories of risk assessment, management of infections, and prophylaxis.

  18. Impaired T cell responsiveness to interleukin-6 in hematological patients with invasive aspergillosis.

    Full Text Available Invasive mold infections (IMI are among the most devastating complications following chemotherapy and hematopoietic stem cell transplantation (HSCT, with high mortality rates. Yet, the molecular basis for human susceptibility to invasive aspergillosis (IA and mucormycosis remain poorly understood. Herein, we aimed to characterize the immune profile of individuals with hematological malignancies (n = 18 who developed IMI during the course of chemotherapy or HSCT, and compared it to that of hematological patients who had no evidence of invasive fungal infection (n = 16. First, we measured the expression of the pattern recognition receptors pentraxin 3, dectin-1, and Toll-like receptors (TLR 2 and 4 in peripheral blood of chemotherapy and HSCT recipients with IMI. Compared to hematological controls, individuals with IA and mucormycosis had defective expression of dectin-1; in addition, patients with mucormycosis had decreased TLR2 and increased TLR4 expression. Since fungal recognition via dectin-1 favors T helper 17 responses and the latter are highly dependent on activation of the signal transducer and activator of transcription (STAT 3, we next used phospho-flow cytometry to measure the phosphorylation of the transcription factors STAT1 and STAT3 in response to interferon-gamma (IFN-γ and interleukin (IL-6, respectively. While IFN-γ/STAT1 signaling was similar between groups, naïve T cells from patients with IA, but not those with mucormycosis, exhibited reduced responsiveness to IL-6 as measured by STAT3 phosphorylation. Furthermore, IL-6 increased Aspergillus-induced IL-17 production in culture supernatants from healthy and hematological controls but not in patients with IA. Altogether, these observations suggest an important role for dectin-1 and the IL-6/STAT3 pathway in protective immunity against Aspergillus.
