The Pituitary


Book Description

The pituitary, albeit a small gland, is known as the "master gland" of the endocrine system and contributes to a wide spectrum of disorders, diseases, and syndromes. Since the publication of the second edition of The Pituitary, in 2002, there have been major advances in the molecular biology research of pituitary hormone production and action and there is now a better understanding of the pathogenesis of pituitary tumors and clinical syndromes resulting in perturbation of pituitary function. There have also been major advances in the clinical management of pituitary disorders. Medical researchers and practitioners now better understand the morbidity and mortality associated with pituitary hormone hyposecretion and hypersecretion. Newly developed drugs, and improved methods of delivering established drugs, are allowing better medical management of acromegaly and prolactinoma. These developments have improved the worldwide consensus around the definition of a "cure" for pituitary disease, especially hormone hypersecretion, and hence will improve the success or lack of success of various forms of therapy. It is therefore time for a new edition of The Pituitary. The third edition will continue to be divided into sections that summarize normal hypothalamic-pituitary development and function, hypothalamic-pituitary failure, and pituitary tumors; additional sections will describe pituitary disease in systemic disorders and diagnostic procedures, including imaging, assessment of the eyes, and biochemical testing. The first chapter will be completely new – placing a much greater emphasis on physiology and pathogenesis. Two new chapters will be added on the Radiation and Non-surgical Management of the Pituitary and Other Pituitary Lesions. Other chapters will be completely updated and many new author teams will be invited. The second edition published in 2002 and there have been incredible changes in both the research and clinical aspects of the pituitary over the past 8 years – from new advances in growth hormones to pituitary tumor therapy. - Presents a comprehensive, translational source of information about the pituitary in one reference work - Pituitary experts (from all areas of research and practice) take readers from the bench research (cellular and molecular mechanism), through genomic and proteomic analysis, all the way to clinical analysis (histopathology and imaging) and new therapeutic approaches - Clear presentation by endocrine researchers of the cellular and molecular mechanisms underlying pituitary hormones and growth factors as well as new techniques used in detecting lesions (within the organ) and other systemic disorders - Clear presentation by endocrinologists and neuroendocrine surgeons of how imaging, assessment of the eyes, and biochemical testing can lead to new therapeutic approaches




Clinical Neuroendocrinology


Book Description

A concise and innovative account of clinical neuroendocrine disorders and the key principles underlying their diagnosis and management.




Pituitary Tumors in Pregnancy


Book Description

Pituitary adenomas account for 10-15% of all intracranial tumors and they frequently impair fertility. The development of medical and surgical therapy for such tumors has turned pregnancy into a reality for women harboring pituitary adenomas. However, gestation risks for both mother and fetus are still of concern for endocrinologists, gynecologists and pediatricians. This book intends to update knowledge on this topic, mainly regarding fertility restoration as well as gestational and post gestational management of patients with pituitary tumors.

Prolactin


Book Description

Hormonal Proteins and Peptides: Prolactin, Volume VIII focuses on the broad spectrum of biological activities of prolactin among the vertebrates. This book discusses the function of prolactin in stimulating crop milk formation in birds as well as in inducing incubation behavior in the ring dove. Organized into five chapters, this volume starts with an overview of the chemistry of prolactin and its role on normal mammary gland growth and function. This text then explores the prolactin effects in tumor induction and growth. Other chapters review the status of the evolutionary biology and comparative endocrinology of prolactin. This book discusses as well the nature of prolactin cells, the control of prolactin secretion, and the nature of the prolactins from various vertebrate sources. The final chapter considers the significant advances in gonadotropins, including prolactin, follitropin, relaxin, and lutropin. This book is a valuable resource for biologists, endocrinologists, zoologists, embryologists, physicians, and medical health professionals.




Prolactin


Book Description

It is an authentic privilege to have the opportunity to assemble and edit a new volume on "Prolactin," the first in several decades to be devoted to this fascinating hormone in all its aspects. The obvious clinical rationale for understanding prolactin (PRL) is the frequent occurrence of prolactinomas, the most common type of pituitary tumor. Fortunately, medical management of prolactinomas can be based on our under standing of the physiology of hypothalamic control of the lactotroph. Armed with this knowledge, therapies for proiactinomas are highly successful and well tolerated. Be cause of the historical and practical importance of knowledge regarding the hypothala mus-Iactotroph axis, the first chapters of this volume are dedicated to reviewing the physiology, development, and cell biology of lactotroph regulation. Chapters focusing on prolactinomas and related clinical issues follow these. PRL is the primary hormone that is responsible for "parental care" in many verte brate species. This reproductive strategy is not unique to mammals, but it has devel oped through evolution to be the central distinguishing feature of the mammalian life cycle. Among the mammals, mice have become the most effective research species in recent years. This can be traced to the development of a wide range of methods for manipulating mouse genetics, and thereby influencing development, physiology and behavior. Mice also provide a profound illustration of the physiological challenges faced in maternity. Female mice undergo a post-partum estrous, and often are both pregnant and lactating simultaneously.




MRI of the Pituitary Gland


Book Description

This clinically oriented book will familiarize the reader with all aspects of the diagnosis of tumors and other disorders of the pituitary gland by means of magnetic resonance imaging (MRI). The coverage includes acromegaly, Cushing’s disease, Rathke cleft cysts, prolactinomas, incidentalomas, nonsecreting adenomas, other lesions of the sellar area, hypophysitis, and central diabetes insipidus. Normal radiologic anatomy and the numerous normal variants are described, and guidance is also provided on difficulties, artifacts, and other pitfalls. The book combines concise text and high-quality images with a question and answer format geared toward the needs of the practitioner. MRI is today considered the cornerstone in the diagnosis of diseases of the hypophyseal-hypothalamic region but the relatively small size of the pituitary gland, its deep location, the many normal anatomic variants, and the often tiny size of lesions can hinder precise evaluation of the anatomic structures and particularly the pituitary gland itself. Radiologists and endocrinologists will find MRI of the Pituitary Gland to be full of helpful information on this essential examination, and the book will also be of interest to internists and neurosurgeons.




Prolactin


Book Description

Lactogenic hormone activity was first observed in bovine pituitary extracts by Stricker and Griiter in 1928, working in Bouin's laboratory in Strasbourg. Since that time prolactin has been shown to exist in anterior pituitary extracts of almost all vertebrate species investigated. Although its biology was extensively studied in many mammalian species, the existence of prolactin in the human was generally doubted, despite the positive evidence produced by such researchers as Pasteels. This can partly be explained by the fact that human growth hormone isolated in 1961, is itself a potent lactogen, in contrast to nonprimate growth hormones, and is present in the normal human pituitary in much greater amounts than prolactin. As a result there was a lag of nearly 10 years until prolactin was unanimously accepted as a hormone of the human pituitary, separate from human growth hormone. In 1970 new bioassay techniques permitted the demonstration of prolactin bioactivity in the serum of postpartum women and galactorrhea patients, and chromatographic methods led to the isolation and purification of human prolactin allowing the establishment of a specific radioimmunoassay for this hormone. This opened the road to the understanding of prolactin physiology and pathophysiology in the human, which has revolutionized clinical neuroendocrinology and reproductive endocrinology. Particularly hyperprolactinemia has turned out to be one of the most common endocrine syndromes.
