Pediatric Neuropsychology Case Studies: From the Exceptional to the Commonplace

by Jennifer Niskala Apps Robert F. Newby Laura Weiss Roberts

In the recent literature, the most influential case study books in neuropsychology are in the adult realm. Pediatric neuropsychology is a rapidly developing field with increasingly greater influence in the assessment, diagnosis, early identification, and treatment of childhood illnesses. This book will provide the first centralized, comprehensive resource for case studies in pediatric neuropsychology. Not only will this supply a valuable compilation for the growing numbers of professionals in this field, but will also serve as an innovative and appealing resource for therapists, teachers, and others interested in child development. This book will be structured in such a way that readers can easily access individual cases of interest, as well as related areas of dysfunction. Section breakdowns will be provided in order to highlight the combined focus of case presentations in acquired neuropsychological dysfunction as well as developmental disorders. Each section will begin with an introductory chapter, highlighting the salient feature of the concept and providing brief, up to date reviews of the current research and theories. Within each global section, individual case studies will serve as stand-alone chapters. Contributing authors will be provided extensive guidance and coaching with regards to the standard format and information to be included in each chapter. The first section of this book will present cases involving neurological disorders. The intention of this section is to provide not only “classic” examples of neurological dysfunction in children, but also to provide interesting cases of unique or remarkable presentations. The second section will present an accumulation of cases representing both common and progressive conceptualizations of developmental disabilities. Section three has been designed to highlight cases which often present complex issues to neuropsychologists. The case examples in this section will highlight the use of alternative treatments, pathologies that are often a source of inquiry, and situations that lack the more rigorous scientific data often utilized in other diagnostic procedures. Additionally, this section may include chapters on common differential diagnosis dilemmas in clinical practice. Often multifaceted and even contradictory evidence can arise during evaluations, resulting in complex or problematic situations for the clinician. Such examples are difficult, by their nature, to forecast, but rather would be added during the book’s development, as they occur.

Forest Ecosystems, Forest Management and the Global Carbon Cycle (Nato ASI Subseries I: #40)

by Michael J. Apps David T. Price

Globally, forest vegetation and soils are both major stores of terrestrial organic carbon, and major contributors to the annual cycling of carbon between the atmosphere and the biosphere. Forests are also a renewable resource, vital to the everyday existence of millions of people, since they provide food, shelter, fuel, raw materials and many other benefits. The combined effects of an expanding global population and increasing consumption of resources, however, may be seriously endangering both the extent and future sustainability of the world's forests. About thirty chapters cover four main themes: the role of forests in the global carbon cycle; effects of past, present and future changes in forest land use; the role of forest management, products and biomass on carbon cycling, and socio-economic impacts.

Imaging in Pediatric Dental Practice: A Guide to Equipment, Techniques and Clinical Considerations

by Johan Aps

This book is a comprehensive guide to dentomaxillofacial imaging in paediatric dentistry and is an excellent resource for both general dental practitioners and paediatric dentists. Radiation protection, radiation doses and potential risks of ionising radiation are discussed, to provide dentists with appropriate information when they are asked about these important issues in their practice. Technical information about X-ray machines, ranging from the intraoral machine to the medical computed tomography machine, as well as the differences between digital image detectors, are explained to the extend a (pediatric) dentist should know. The latter is important to understand why certain exposure settings are used and what the advantages or disadvantages are of the machines and the image detectors. Non-ionising radiation techniques, magnetic resonance imaging and ultrasonography, are also explained, as well are their applications in the field of dentomaxillofacial radiology. Knowing which imaging technique will provide the best diagnostic images possible, is key to every clinical case a dentist is faced with. A wide range of clinical examples are displayed in this book, ranging from incidental findings to malignant pathology. All are illustrated with radiographic material and explained, in order to give the reader a good sense of what to look for when assessing radiographs in the dentomaxillofacial field

MHC Class I Antigens In Malignant Cells: Immune Escape And Response To Immunotherapy (SpringerBriefs in Cancer Research #1)

by Natalia Aptsiauri Angel Miguel Garcia-Lora Teresa Cabrera

Abnormal expression of MHC class I molecules in malignant cells is a frequent occurrence that ranges from total loss of all class I antigens to partial loss of MHC specific haplotypes or alleles. Different mechanisms are described to be responsible for these alterations, requiring different therapeutic approaches. A complete characterization of these molecular defects is important for improvement of the strategies for the selection and follow-up of patients undergoing T-cell based cancer immunotherapy. Precise identification of the mechanism leading to MHC class I defects will help to develop new personalized patient-tailored treatment protocols. There is significant new research on the prevalence of various patterns of MHC class I defects and the underlying molecular mechanisms in different types of cancer. In contrast, few data is available on the changes in MHC class I expression during the course of cancer immunotherapy, but the authors have recently made discoveries that show the progression or regression of a tumor lesion in cancer patients undergoing immunotherapy depends on the molecular mechanism responsible for the MHC class I alteration and not on the type of immunotherapy used. According to this notion, the nature of the preexisting MHC class I lesion in the cancer cell has a crucial impact on determining the final outcome of cancer immunotherapy. This SpringerBrief will present how MHC class 1 is expressed, explain its role in tumor progression, and its role in resistance to immunotherapy. ​

Social Recognition in Invertebrates: The Knowns and the Unknowns

by Laura Aquiloni Elena Tricarico

This book uses a wide range of case studies from different invertebrate taxa to describe the numerous forms of social recognition occurring in this large group of animals and traces the evolution of this cognitive ability. The authors provide several examples of direct (i.e. the target of recognition is a conspecific) and indirect recognition (i.e. recognition of a reliable proxy rather than an individual, such as a den or a substrate) and discuss cases of familiar recognition (i.e. an animal remembers a conspecific but cannot tell what class it comes from or recognize its identity). Class-level recognition (i.e. an animal assigns a conspecific to an appropriate class of animals), and true individual recognition (i.e. an animal both identifies and recognizes a conspecific on an individual basis) are also addressed.

Representing Electrons: A Biographical Approach to Theoretical Entities

by Theodore Arabatzis

Both a history and a metahistory, Representing Electrons focuses on the development of various theoretical representations of electrons from the late 1890s to 1925 and the methodological problems associated with writing about unobservable scientific entities. Using the electron—or rather its representation—as a historical actor, Theodore Arabatzis illustrates the emergence and gradual consolidation of its representation in physics, its career throughout old quantum theory, and its appropriation and reinterpretation by chemists. As Arabatzis develops this novel biographical approach, he portrays scientific representations as partly autonomous agents with lives of their own. Furthermore, he argues that the considerable variance in the representation of the electron does not undermine its stable identity or existence. Raising philosophical issues of contentious debate in the history and philosophy of science—namely, scientific realism and meaning change—Arabatzis addresses the history of the electron across disciplines, integrating historical narrative with philosophical analysis in a book that will be a touchstone for historians and philosophers of science and scientists alike.
