Blood Science is a relatively new discipline which merges biochemistry, haematology, immunology, transfusion science and genetics. This bringing together of traditional disciplines requires a corresponding change in education and training for healthcare scientists and Blood Science: Principles and Pathology is written in response to this emerging need. An introduction to the subject and an overview of the techniques used in blood science are followed by a series of chapters based on groups of analytes investigated in blood - red blood cells, white blood cells and platelets, followed by the constituents of plasma, including waste products, electrolytes, glucose, lipids, enzymes, hormones, nutrients, drugs, poisons and others. Each chapter is supported by learning objectives, summaries and further information, and a focus is given to chapter specific case studies with interpretation to demonstrate how laboratory data in conjunction with clinical details is utilised when investigating patients with actual or suspected disease. Finally, a separate chapter offers more detailed case reports that integrate the different aspects of blood science. Undergraduate students taking blood science modules as part of their BSc programmes in Biomedical and Healthcare Sciences will appreciate the level of integration between clinical biochemistry and haematology. In addition, this book will provide suitable initial reading for those students embarking on blood science modules on MSc programmes and will be of value to new graduates entering the profession and starting their career in blood science departments by supplementing practice-based training with the required theoretical underpinning. This book is approved by the Institute of Biomedical Science and written by its expert writers, many of whom work on the Institute s advisory panels.

Blood has long been viewed as a conduit for therapy, stemming from the ancient days of phlebotomy to remove evil humors to the development of successful blood transfusions to replace missing blood components. The identification and characterization of hematopoietic stem cells by Drs. Till and McCulloch revolutionized the field and soon after, non-hematopoietic stem and progenitor cells were characterized from the blood and bone marrow. Some of these cell types and various blood-derived cell lineages are involved in the repair of various types of tissue damage that span the spectrum of medical disorders. The goal of this book is to provide an up-to-date review of the various types of blood-derived cells with regenerative capacity, identify opportunities for intervention by examining specific clinical applications, and recognize the regulatory environment that will encompass future therapies in regenerative medicine.

The aim of Hematologic Malignancies: Methods and Techniques is to review those methods most useful for the diagnosis and subsequent mana- ment of hematologic malignancies. The scope of coverage is intentionally broad, ranging from routine procedures to highly sophisticated methods not currently offered by most clinical laboratories. The latter methods were selected especially to bring into focus recent advances in molecular biology that, since they provide us with strong tools for assessing the outcome of upcoming therapeutic modalities intent on disease eradication, are expected to impact the future diagnosis and management of these diseases. Thus, the c- mon thread among all chapters is clinical relevance, whether sanctioned by past experience or by the expectation that seemingly esoteric research techniques of today will prove clinically valuable in the future. Hematologic Malignancies: Methods and Techniques is primarily a compilation of methods presented in sufficient detail-by authors with extensive expertise in their field-to serve not only as a reference for seasoned research and clinical laboratory pers- nel, but also as a guide for the less experienced. Moreover, the contributing authors also discuss the pathophysiologic bases and the diagnostic usefulness that underscore each method's clinical relevance. Thus, this volume should be also valuable to clinicians-especially hematologists, oncologists, and path- ogists-often bewildered by an ever increasing flow of new scientific inf- mation, the practical application of which is often either not clearly disclosed or difficult to discern.

This volume is the first of its kind to emphasize the visual approach in the diagnosis of cutaneous lymphoid infiltrates. Written and designed in an accessible yet highly detailed format by an expert in the field, this book bridges the knowledge gaps so often found when dealing with skin lymphomas. Complete with more than two hundred high quality images and illustrations, Diagnosis of Cutaneous Lymphoid Infiltrates offers pearls and pitfalls as well as differential diagnoses. Additionally, images are explained and decoded with the use of illustrations and analogies, proving to be an invaluable resource for pathologists, dermatologists, dermatopathologists, hematopathologists, and residents and fellows in these fields.

The sixth meeting on the use of resealed annealed red blood cells was held in Irsee, Germany by the International Society for the Use of Resealed Erythrocytes (ISURE) on July 25-28, 1996. Although earlier meetings focused on the technology toward develop ment of methods and standardization for efficient, consistent encapsulation, most of the present studies now are directed toward the application use of these carrier blood cells. Basic studies now have been directed toward exploration of commercial applications. In deed, clinical trials were initiated to evaluate the dose-response curves employing L asparagenase in human patients. Also, studies have shown the use of thrombolytic agent in erythrocyte carriers with the use of human red blood cells to provide a new conceptual ap proach in thrombolytic therapy to prevent thrombosis in individuals with higher risk fac tors. For example, with the use of carrier red blood cells, the thrombolytic agents will have a greater potential of acting on clot formation without systemic activation and thus lower the risk of hemorrhage, which is always prevalent in the thrombolytic therapy."

The author examines hemostasis in animals from all seven major vertebrate classes.

This monograph is a valuable reference for students, researchers, and teachers of biology, zoology, veterinary science, and human medicine.

This is an essential guide to the data, basic science, outcome studies and decision-making processes involved in blood and marrow stem cell transplantation. Organized according to disease types and procedures, it contains more than 100 tables, figures and algorithms that reflect up-to-date research and give guidance on the choices between different types of chemotherapy, autologous vs. allogeneic transplantation, peripheral blood vs. bone marrow stem cells, and standard vs. experimental treatments. This new edition summarizes the research of the last four years and gives mature data for all established indications, such as acute myeloid leukemia, myelodysplastic syndrome and Hodgkin and non-Hodgkin lymphomas. New chapters discuss global trends in stem cell transplantation, cellular therapies including donor lymphocytes, and pediatric neurologic and metabolic disorders. With an expanded complications section, links to electronic databases and discussion of new drugs and alternative stem cell sources, this text belongs in every transplant unit.

Analysis of blood gas can be a daunting task. However, it is still one of the most useful laboratory tests in managing respiratory and metabolic disorders. Busy medical students have struggled ineffectively with Hasselbach's modification of the Henderson equation, been torn between the Copenhagen and the Boston schools of thought; and lately, been confronted with the radically different strong-ion approach. In modern medical practice, the health provider's time is precious: it is crucial to retain focus on those aspects of clinical medicine that are of key importance. Adoption of an algorithm-based approach in the study of topics that are hard to understand (particularly those that are rooted in clinical physiology) can be extremely advantageous. Handbook of Blood Gas/Acid-Base Interpretation, 2nd edition, is organized in a logical sequence of flow charts that introduce concepts and gradually build upon them. This approach facilitates understanding and retention of the subject matter. Medical students, residents, nurses, and practitioners of respiratory and intensive care will find it possible to quickly grasp the principles underlying respiratory and acid-base physiology, and apply them effectively in clinical decision making.

In Chronic Leukemias and Lymphomas: Clinical Management, a panel of recognized experts in hematological oncology describe the unique biological features of indolent hematologic neoplasms, providing powerful insight into their clinical manifestation, highlighting potential targets for novel therapies, and distinguishing these disorders from aggressive lymphoma and Hodgkin's disease. In their integrated surveys of these chronic myeloproliferative and lymphoproliferative disorders, the authors emphasize such unique entities as prolymphocytic leukemias and cutaneous lymphomas. Special emphasis is given to the mechanisms of disease progression with authoritative insights into the promising new era of antineoplastic pharmacology.

Relapse of leukemia following successful remission-induction therapy remains a major obstacle in the treatment of patients with acute leukemia. Leukemia recurs most frequently in patients with acute myeloblastic leukemia (AML) and high risk acute lymphoblastic leukemia (ALL) following chemotherapy and less often in patients with low risk ALL and particularly in patient groups> submitted to allogeneic marrow transplantation. ' It is likely that the great majority of these recurrences originate from residual leukemic cells that survive initial remission-induction chemotherapy. Today, several research groups throughout the world place emphasis on studies concerned with the detection and treatment of 'minimal residual disease' (MRD). These investigations are conducted with the common objective to tackle the remaining cells. 'Minimal Residual Disease in Acute Leukemia: 1986' summarizes the fast advancements in this area. Several disciplines are concerned with the analysis of leukemic cells. The perspectives of cytogenetic and molecular genetic approaches for applica tion in the detection of MRD are reviewed. In this respect, modern cyto genetics provide highly specific tumor markers. The resolution of cyto genetic methods can be particularly improved when combined with other techniques which select relevant subpopulations of cells. Characterization of oncogenes and gene rearrangements, including those of immunoglobulin and T-cell receptor genes, and the measurement of gene products, have been established. Techniques based on these approaches offer interesting tools for the detection of MRD. New possibilities of employing monoclonal anti bodies are also presented.

The task the editors have set themselves is to survey the field of clinical hemorheology from basic principles to up-to-date research. It is only in a new science like this that it is possible to span the whole field in a book of this size. Hemorheology, as a new approach to the study and management of a wide range of circulatory diseases, is now beginning to appear with increasing frequency in general as well as specialized medical journals. Hemorheology is also just beginning to creep into the undergraduate medical curriculum. Therefore, the majority of graduate doctors are unequipped to assess the place of hemorheology in the overall framework of circulatory physiology and pathology or to assess its relevance to their everyday practice. It is hoped that this book will fill this gap. The approach of the book is interdisciplinary. The first part deals with basic principles of blood flow, circulation and hemorheology. It has been written with the general doctor in mind, who has no special knowledge of hemodynamics and rheological concepts, terminology or methodology. To maintain the emphasis on practical clinical applications, all the chapters in the second part of the book have been written by clinical specialists practicing in the individual areas of disease. The book is so designed that clinicians may be able to read the relevant chapters in the second part of the book in isolation, using the basic science aspects contained in the first part of the book as reference chapters.

This succinct resource provides an ideal balance of the biology and practical therapeutic strategies for classic and non-classic BCR-ABL-negative myeloproliferative neoplasms. Utilizing current World Health Organization nomenclature, classification, and diagnostic criteria, international experts have assembled to convey the most up-to-date knowledge in this rapidly evolving field. The opening chapters cover the diagnosis and classification, genetics, cytogenetic findings, and prognostic factors of MPNs. Further chapters explore therapies specific to the different disease entities, including polycythemia vera, essential thrombocytopenia, myelofibrosis, and eosinophilic disorders, and mastocytosis. Unique areas of discussion include JAK2 inhibitor therapy, hematopoietic stem cell transplantation, and blastic transformation. A valuable reference for practicing hematologists, this forefront book enriches our understanding of recent discoveries and their impact on conventional and investigational treatments.

Authoritative experts in transfusion medicine describe in critical detail the most important procedures for obtaining, selecting, and transfusing red blood cells to patients. The topics covered include such key issues as transfusion problems in the immunocompromised, the complications of autoantibodies, transfusion of infants with hemolytic disease, difficulties arising from solid organ transplantation, stem cell transfusions, and the challenges of massive transfusion. Also discussed are the use, limitations, and alternatives to autogeneic cells; long-term red cell transfusion; the management of adverse reactions to red cell transfusions; and the question of blood group antigens and their association with disease and differential diagnosis. The book offers transfusion specialists fresh insights and information to maximize and extend their current knowledge.

Hematopathology: Genomic Mechanisms of Neoplastic Diseases will keep physicians abreast of the rapid and complex changes in genomic medicine, as exemplified by the molecular pathology of hematologic malignancies. This timely volume will update physicians on the complexities of genomic lesions, as well as offer an integrated framework encompassing molecular diagnosis, the new WHO classification of hematologic neoplasms with focus on molecular pathology, prognostic value of molecular tests, and molecular monitoring of response to gene-targeted therapy. As such, it will be of great value to hematologists, oncologists, pathologists, internal medicine and pediatric specialists, as well as bioscientific staff and laboratorians in private hospitals and academic institutions.

Exciting new "biologic" therapies for treating leukemia are appearing so rapidly that clinicians often find it difficult to make informed decisions about their use when making patient treatment decisions. Biologic Therapy of Leukemia summarizes and reviews all the available data concerning these cutting-edge biologic therapies so that practicing clinicians can make the correct patient-care choices. Here the busy physician will find in one convenient place crucial information on the uses and limitations of the major biologic therapies for leukemia, the different biologic strategies for its treatment, the management of patients being treated with such biologic agents, and the current and future role of emerging biologic agents.

Multiple myeloma is the second most common hematologic malignancy and c- rently affects approximately 50,000 people in the United States. Each year about 20,000 people are diagnosed with myeloma. Although new treatments have been developed, which signi?cantly prolong the survival of patients, myeloma bone d- ease still remains a major cause of severe morbidity and increased mortality in patients with myeloma. Myeloma bone disease is characterized by "punched out" lytic lesions caused by increased osteoclastic bone destruction accompanied by suppressed or even absent osteoblast activity. Advances in our understanding of both the pathophysiology of myeloma bone disease and the development of novel agents that target speci?c pathways involved in both the increased osteoclast f- mation and the suppressed osteoblast activity in myeloma provide new hope for these patients. The treatment of myeloma bone disease was revolutionized by cl- ical trials that demonstrated the signi?cant bene?t of intravenous bisphosphonate therapy in patients with myeloma bone disease. With the identi?cation of many of the cytokines and chemokines involved in myeloma bone disease, novel th- apies such as denosumab that blocks RANKL activity, anti-DKK1, which targets the inhibition of osteoblast activity by blocking Wnt signaling inhibition, and the potential anabolic effects of agents such as bortezomib and activin have greatly improved our potential to block the progression or reverse myeloma bone disease.

Examination of the bone marrow has always been, and to-date techniques whose application will undoubtedly to a large extent still is, within the domain of the haema increase in the future. tologist. This is because smears of bone marrow aspirates After lengthy discussions and enquiries, the conclusion together with peripheral blood films and results of other was reached that the magnifications of most of the tests and investigations provided the information on which illustrations could be omitted without detracting from the usefulness of the Atlas. The magnifications used are the clinical diagnosis was based. Recently, the widespread availability of both improved indicated in Fig. 1.25. In addition, not every detail specif biopsy needles and techniques for processing has greatly ically indicated in a figure or its legend is necessarily increased the number of routinely taken bone biopsies mentioned in the text; and often a range of observations and placed the examination of bone marrow biopsy is illustrated and in these cases the legends are self sectiors also in the field of histopathology - so that explanatory. this Atlas is one of the Current Histopathology series. This Atlas is directed to haematologists and to histo Therefore, the haematologist and the histopathologist pathologists and to anyone interested in the investigation now complement each other in the interpretation of bone and understanding of the human bone marrow. marrow smears, imprints and sections, thus utilizing all available information and expertise to arrive at a diagnosis.

Inspite of considerable progress in prevention, diagnosis, and treatment, pulmonary embolism has remained a threat to the patient and a challenge for the physician both in conservative, as well as in operative disciplines. Pulmonary embolism is according to pathology observations still the most frequently overlooked clinical diagnosis. In 1-5 per 100 autopsies, clinically unexpected pulmonary emboli are found. In addition, the sequelae of recurrent pulmonary emboli, the syndrome of pulmonary hypertension with or without right heart failure, continues to present a therapeutic dilemma - and no progress is in sight. In intensive care medicine pulmonary embolism, either acute, massive, and/or recur- rent, continues to be both a therapeutic as well as a preventive challenge mobilizing pharmacotherapeutic, catheter-interventional, and operative resources. Diagnostic, therapeutic, and preventive strategies are currently in use. Their basis, however, seems surprisingly thin, as far as our knowledge on the natural course of this chameleon-like illness with and without fibrinolytic, anticoagulative, catheter or opera- tive treatment is concerned. A large European multicenter register has been initiated by Professors Kasper and Geibel with the help of Boehringer Ingelheim Pharmaceutics, in order to better describe the natural course of pulmonary embolism under current treat- ment modalities. Furthermore, recently the clinical significance of the valve patent foramen ovale as a source of paradoxical emboli is beginning to be better understood. Many concepts therefore require revision.

The rates of acute leukemia cure have gradually improved over the last decade. Clinical study results reflect the impact of chemotherapy intensity and duration, the role of prolonged maintenance, intensified consolidation or very early intensification. Further progress has also been achieved in bone marrow trans plantation, and recent prospective studies and meta-analyses have contributed comparisons of the high antileukemic efficacy of bone marrow transplantation to that of improved chemotherapy. This allows a more successful combining of the two forms of treatment. New prognostic factors have emerged from both cytogenetic and molecular genetic research. Thus, the Philadelphia chromosome translocation and the bcr/abl gene rearrangement have proven to be the dominating risk factor in acute lymphoblastic leukemia. Since the frequency increases with age, differences in prognosis between children and adults can be explained. Evaluation of molecular and immunologic leukemia cell markers has provided a better understanding of residual leukemia in clinical remission, as a prognostic factor and in monitoring the effectiveness of the antileukemic strategy. Recent work on leukemic cell biology has resulted in novel therapeutic approaches such as terminal differentiation by all-trans-retinoic acid, modulation of chemotherapy by hematopoietic growth factors such as GM-CSF and enhancement of immunologic control by cytokines such as interleukin 2. New antimicrobial drugs and the application of mostly empiric anti-infectious strategies have helped reducing the therapeutic risk. Thus, a number of recent achievements have provided us with new options in the management of patients with acute leukemias."

J. DE GROOTE One of the most ominous and troublesome complications of the liver disease is the appearance of hemorrhagic phenomena. Many careful clini- cal observations about the relationship of liver function and of bilia- ry tree pathology have been published. A vast amount of research work has been devoted to the subject. The severity of the hemorrhagic disor- der is usually in relation to the liver disease. In mild chronic hepa- titis or short lasting obstruction slight subcutaneous or mucosal blee- ding may (lraw the attention of the patient and the doctor, but they are as such far from dangerous. However in acute hepatic insufficiency, in biliary cirrhosis the bleeding tendency is to be considered as a life threatening complication in about half of the cases. Moreover coagulation disturbances aggravate bleeding not only from ruptured oesophageal or gastric varices but also from gastritis or peptic ulcer. 11enometrorrhagia, epistaxis and gingival bleeding may be very trouble- some in these conditions. The use of diagnostic procedures sucl. as liver puncture biopsy and peritoneoscopy are often impossible when platelets and prothrombine time are too low. In order to overcome this difficul- ty a procedure has been worked out taking a biopsy through a trans- jugular catheter placed in the hepatic vein. If a bleeding from the liver occurs it will be in the circulatory system and not cause any trouble.
