Book Description
The exponential increases in neurodevelopmental disorders implicate both genetic causes and environmental factors. Flame-retardants, pesticides, plasticizers, and other every-day products contain chemicals shown to affect thyroid hormone signaling, which if disrupted can result in significant impairment to IQ. Across entire populations, such effects spell large-scale social and economic consequences. In this book Barbara Demeneix suggests what can and must be done to halt and reverse this disturbing trend.

Book Description
Thyroid hormone plays an important role in development and functional maintenance in the central nervous system. Deficiency of thyroid hormone during fetal and early postnatal life induces abnormal development known as cretinism in humans. However, the molecular mechanism of thyroid hormone action has not yet been fully understood. Thyroid hormone action in the brain may be disrupted under various pathological conditions. In addition, environmental factors including endocrine-disrupting chemicals and bacterial endotoxins may disrupt thyroid hormone action in brain, causing abnormal brain development and functional disruption. This is a first book to comprehensively describe the effect of thyroid hormone disruption in the central nervous system. The first section deals with the disruption of thyroid hormone action at the molecular level. First the authors provide a summary of the possible molecular mechanisms of thyroid hormone action in the brain, then they discuss several factors that may disrupt thyroid hormone action. In the second section, animal models to study thyroid hormone action will be introduced. An interesting character of thyroid hormone deficiency is that, without thyroid hormone, the thyroid hormone receptor may act as a “repressor” of gene expression, causing more severe consequence than those of thyroid hormone receptor knockout animals. Thus, several different kind of animal models may be used to clarify the role of thyroid hormone and its receptor in the brain. In the third section, human studies on thyroid disease and neurodevelopment will be introduced. Although endemic cretinism induced by iodine deficiency and sporadic cretinism by various thyroid mutation are well known, the pathophysiological mechanisms that create each abnormal phenotype are not fully understood. ​

Book Description
In recent years, several scientific papers have highlighted the role of the thyroid system in cardioprotection, and several clinical studies – including multicenter studies – have identified the role of thyroid hormones (TH) in the development and progression of cardiovascular disease, making an update of TH and heart relationship both necessary and timely. This second edition of Thyroid and Heart failure provides a careful and updated review of the experimental, clinical and epidemiological results in the field of TH and heart failure, with a particular focus on the translational - bench to bedside - significance of the obtained results. It discusses topics such as the molecular, structural, functional, cellular and histological cardiac changes; the reversibility of these changes with TH replacement therapy; the systemic effects – kidney, hormonal pathways systems, brain, muscle, etc – of altered TH metabolism in HF, as well as the clinical and prognostic implications. The section devoted to the potential therapeutic treatments has been expanded. Thanks to its translational approach to this highly complex subject, the book will be of interest to a broad readership, including cardiologists, endocrinologists and internists.

Book Description
This volume contains the proceedings of a conference held at the National Institutes of Health in Bethesda on March 21-23. 1988. jointly sponsored by the International Council for Control of Iodine Deficiency Disorders (ICCIDD) and the Fogarty International Center of the National Institutes of Health. Several themes converged to make this meeting timely. The first is an increasing awareness of iodine deficiency disorders as a world-wide problem of public health and a preventable cause of mental deficiency. and as a subject of scientific effort. Increased interest in these problems owes a great deal to accessibility to remote and under developed areas of the world where iodine deficiency persists. As with any subject. greater scrutiny yields unexpected complexity and interest. It is true that provision of iodine. typically as iodized salt, is the necessary and sufficient preventative for iodine deficiency disorders. without including endemic cretinism. This provision is a governmental, economic and social problem. Apart from this, however, the scientific and medical problem of iodine deficiency and its effect on brain development and function is one of great interest and importance for developmental neurology and psychology. Even though the specific preventative agent is known, we do not totally understand the neurobiological questions raised.

Book Description
This book provides concise and cutting-edge studies on threats resulting from exposure to environmental chemicals that can affect human health and development, with a particular emphasis on the DOHaD concept. The book is divided into five main parts, the first of which includes an introduction to the impacts of developmental exposure to environmental chemicals and historical perspectives, while the second focuses on how environmental chemicals can affect human organs, including neurodevelopment, immune functions, etc. In turn, the third part addresses the characteristics of specific chemicals and their effects on human health and development, while the fourth part provides a basis for future studies by highlighting the latest innovations in toxicology, remaining challenges, and promising strategies in children’s environmental health research, as well as ideas on how to bridge the gap between research evidence and practical policymaking. The fifth and last part outlines further research directions and related policymaking aspects. Health Impacts of Developmental Exposure to Environmental Chemicals will appeal to young and veteran researchers, students, and physicians (especially gynecologists and pediatricians) who are seeking comprehensive information on how children’s health can be affected by harmful chemicals and other environmental toxicants.

Book Description
As is the case in all fields of medicine, developmental endocrinology is now being studied at the molecular level. In this volume world-class researchers review the advances of the past decade in the study of normal and abnormal organogenesis of the thyroid gland and of the ontogeny of its function. They describe human thyroid development and its defects with the help of genetic studies in mouse models. Genetic defects of thyroid hormone synthesis are covered and their clinical relevance debated. The important field of thyroid cancer in the context of spontaneous occurrence and as part of familial neoplasia syndromes is described in detail. Finally, the important problem of environmental iodine deficiency which has emerged as a global public health concern is addressed. For the first time, a decade of work is presented in a concise and highly readable form. Offering valuable insight both for senior clinicians and graduate students, this publication will be of central interest to basic scientists involved in developmental biology as well as to pediatricians and endocrinologists dealing with patients with congenital disorders of thyroid function.

Book Description
Behavioral toxicology is a young discipline in the United States; so young, in fact, that this is one of its first books. Behavioral questions are bound to play a major role in future scientific work and governmental decisions involving the health effects of environmental contaminants and other chemicals. This role springs from two key problems that face scientists and public agencies required to set acceptable exposure standards or to determine criteria for the toxicity of therapeutic chemicals: How do you evaluate effects that may show up only as subtle functional disturbances? And how do you de tect toxic effects early enough so that they may still be reversible, before they produce major damage? The contributions in this book come from a collection of scientists whose interests span a wide variety of problem areas. The focus is largely on me thodological issues because they represent the most immediate concern of the discipline. We expect that this collection of papers will represent a useful source book for behavioral toxicology for some time. For the past few years, the University of Rochester's Department of Radiation Biology and Biophysics has sponsored a series of international conferences on chemical toxicity, partly as a response to concern over the con sequences to health of the rich chemical soup in which we live. This book is based upon presentations made to the fifth of the series. Held in June, 1972, it was the first formal meeting devoted to behavioral toxicology in this country.

Book Description
This book is an up-to-date and comprehensive guide to all the common thyroid disorders that may be seen by internists, endocrinologists, nuclear medicine physicians, and endocrine surgeons. While the fundamentals of thyroid hormone function and regulation in health and disease are well covered, the primary focus is on the clinical approach to thyroid disease, with detailed coverage of both initial diagnosis and management and the role of imaging. Because most endocrine diseases are chronic and lifelong, special emphasis is placed on long-term management and the common pitfalls that may be encountered by the clinician. The editors are internationally acknowledged leaders in the field of thyroid disease and have gathered an outstanding team of authors, all of whom are also highly expert in their respective areas, but who, equally importantly, write in a clear and lucid style. The numerous isotope scan and ultrasonographic images ensure that the book will serve as a valuable reference atlas to which the physician will return again and again.
