Book Description
Responding to a renewed interest in the growing problem of iodine deficiency worldwide, Drs. Charles Oxnard and Peter Obendorf, along with experienced translator and anatomist John Dennison, take a fresh look at the classic text, Der endemische Kretinismus, published in 1936 by Springer. Translated here for the first time into English, this landmark text will be a welcome resource for researchers confronting the problem of iodine deficiency. Oxnard and Obendorf point out that there is very little detailed knowledge or numerical data on cretinism available in the English-speaking world. In addition, highly-renowned Professor Basil S. Hetzel, recently-retired World Health Organization Chairman of the International Council for Control of Iodine Deficiency Disorders, published in 2009 with Dr Chen Zu-pei on the resurgence of iodine deficiency in China. Indeed, throughout the entire developing world there may be as many as two billion people at risk to iodine deficiency; perhaps three quarters of a billion have goiter, and ten million may be cretins. Even in developed countries, iodine deficiency is re-emerging (as in New South Wales in 19% of children) with the result of significantly reduced numbers of gifted children (though this is not cretinism per se). Certain to be of significant interest to a wide range of researchers, health providers and professionals, including government health administrators, this English translation of Endemic Cretinism is a major contribution to the literature.

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
When the Medicare program was established in 1965, it was viewed as a form of financial protection for the elderly against catastrophic medical expenses, primarily those related to hospitalization for unexpected illnesses. The first expansions to the program increased the eligible population from the retired to the disabled and to persons receiving chronic renal dialysis. It was not until 1980 that an expansion of services beyond those required "for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member" was included in Medicare. These services, known as preventive services, are intended either to prevent disease (by vaccination) or to detect disease (by diagnostic test) before the symptoms of illness appear. A Committee was formed "to conduct a study on the addition of coverage of routine thyroid screening using a thyroid stimulating hormone test as a preventive benefit provided to Medicare beneficiaries under Title XVIII of the Social Security Act for some or all Medicare beneficiaries."

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
How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Book Description
Over two billion people worldwide are at risk for the spectrum of disorders known as "The Iodine Deficiency Disorders." 1-10% will suffer cretinism; 5-30% will have some sort of brain damage or neurological impairment and 30-70% will be hypothyroid. The causes of iodine deficiencies can be considered from both simplistic and more complex perspectives: From the leaching of iodine from soil resulting in crops with low iodine content to malnutrition resulting in impaired iodine absorption. Poor dietary diversification and impoverished socio-economic development can also lead to iodine deficiencies. Although it is possible to diagnose and treat deficiencies, there is still an ongoing dialogue regarding the detailed molecular pathology of iodine homeostatis, how hypothyroidism impacts the body tissues, and efficient diagnosis and treatment of the Iodine Deficiency Disorders. This Handbook provides a resource of information on the various pathways and processes based on different countries or diseases. Because there is a constant flow of new information on iodine and related disorders, the goal of this Handbook is to provide a base of scientific information upon which additional knowledge can be applied. - Provides important information on one of the most common micro-nutrient deficiencies in the world, the most important "single nutrient-multiple consequences" paradigm today - Includes information on iodine-related diseases, including those that are common, preventable and treatable - Provides insight from a broad perspective of viewpoints -- from subcellular transports to economic impact

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
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. ​
