TNM Supplement: A Commentary on Uniform Use (UICC)
by Christian Wittekind James D. Brierley Anne Lee Elisabeth Van EyckenThe Union for International Cancer Control's (UICC) TNM classification system is the most widely used cancer classification and staging system in the world. It is used to describe the anatomical extent of disease and it is essential to patient care, research and cancer control. This fifth edition of the TNM Supplement: A Commentary of Uniform Use offers practitioners a wealth of material intended to complement the system's day-to-day use. The volume features: Updated definitions of terms used in cancer staging. New sections on carcinomas of the thymus, sarcomas of the spine and pelvis and soft tissue sarcomas of the head and neck, and comprehensive updates to the head and neck carcinomas, carcinomas of the lung and neuroendocrine tumours sections. Frequently asked questions from the UICC helpdesk. The Supplement may be treated as a companion text to the recent eighth edition of the TNM Classification of Malignant Tumours (978-1-119-26357-9), supporting the correct and uniform application of the TNM classification system. The TNM Supplement can also be utilised as a standalone book, providing explanations and examples to answer many questions that arise during the daily use of the TNM cancer classification and staging system, particularly in unusual cases.

TNM Supplement 1993: A Commentary on Uniform Use (UICC International Union Against Cancer)
by P. Hermanek, D. E. Henson, R.V.P. Hutter and L.H. SobinThe fourth edition of the TNM Classification was published in 1987,1 and a revision in 1992.2 It was the result of efforts by all national TNM Committees towards a worldwide uniform classification. The classifica tion criteria are identical with the fourth edition of the Manual for 3 Staging of Cancer of the American Joint Committee on Cancer (AJCC). Although the classification has found wide acceptance, some workers have pointed out that individual definitions and rules for staging are not sufficiently detailed. This can lead to inconsistent application of the clas sification. the antithesis of standardization. This source of differences in interpretation applies not only to the classification of individual organs but also to the general rules of the system, especially to the definitions of the requirements for the pathological classification (pT, pN). These are specified only for carcinoma of the breast; for other sites, reference must be made back to the general rules. which can lead to variable interpreta tions. The TNM Project Committee of the UICC has addressed this prob lem and collected and considered the criticisms and suggestions from the national TNM Committees as well as from cancer registries, oncolo gical associations and individual users. The result was the decision to complement the 4th edition of the TN M Classification 1.2. 3 with the publi cation of a TNM Supplement containing recommendations for the uni form use of TNM.

To Cast Out Disease: A History of the International Health Division of Rockefeller Foundation (1913-1951)
by John FarleyThough one of the most important public health agencies of the 20th century and the most powerful and richest branch of the Rockefeller Foundation, the International Health Division's history (1913-1951) has never been told before. This original work is based on a vast multitude of letters, reports and photographs the author uncovered in the Rockefeller Archives. Farley describes the internal struggles and the conflicts with foreign and US governments of the "medical barons" who ran the organization as they set its goals and tried to eradicate some of the world's most serious diseases. He also describes the first testing of DDT and the preparation for the US army of a yellow fever vaccine that turned out to be contaminated. He takes the reader into the often byzantine world where the organization endowed schools of public health and nursing in such diverse places as London, Toronto, fascist Rome, militaristic Tokyo, and Calcutta in the dying days of the British Raj. Farley enlivens the book with sketches of the personalities and prejudices of those who worked in the Division and of the scandals that rocked it from time to time. He shows that in the continuing debate between those who believe that disease is the root cause of ill health and poverty and those who see poverty as the primary cause, the Division remained firmly in the former position. He also shows that after it closed, former members exerted considerable influence on the development of the World Health Organization. Opposing some recent historians, Farley argues against the view that the Health Division served as an advance guard for American capitalism. His lively book will be welcomed by all who are interested in the history of public health, tropical disease, and medical institutions.

To Comfort Always: A history of palliative medicine since the nineteenth century (Oxford Medical Histories)
by David ClarkPalliative medicine was first recognised as a specialist field in 1987. One hundred years earlier, London based doctor William Munk published a treatise on 'easeful death' that mapped out the principles of practical, spiritual, and medical support at the end of life. In the intervening years a major process of development took place which led to innovative services, new approaches to the study and relief of pain and other symptoms, a growing interest in 'holistic' care, and a desire to gain more recognition for care at the end of life. This book traces the history of palliative medicine, from its nineteenth-century origins, to its modern practice around the world. It takes in the changing meaning of 'euthanasia', assesses the role of religious and philanthropic organisations in the creation of homes for the dying, and explores how twentieth-century doctors created a special focus on end of life care. To Comfort Always traces the rise of clinical studies, academic programmes and international collaborations to promote palliative care. It examines the continuing need to support development with evidence, and assesses the dilemmas of unequal access to services and pain relieving drugs, as well as the periodic accusations of creeping medicalization within the field. This is the first history of its kind, and the breadth of information it encompasses makes it an essential resource for those interested in the long-term achievements of palliative medicine as well as the challenges that remain.

To End a Plague: America's Fight to Defeat AIDS in Africa
by Emily Bass&“Randy Shilts and Laurie Garrett told the story of the HIV/AIDS epidemic through the late 1980s and the early 1990s, respectively. Now journalist-historian-activist Emily Bass tells the story of US engagement in HIV/AIDS control in sub-Saharan Africa. There is far to go on the path, but Bass tells us how far we&’ve come.&” —Sten H. Vermund, professor and dean, Yale School of Public Health With his 2003 announcement of a program known as PEPFAR, George W. Bush launched an astonishingly successful American war against a global pandemic. PEPFAR played a key role in slashing HIV cases and AIDS deaths in sub-Saharan Africa, leading to the brink of epidemic control. Resilient in the face of flatlined funding and political headwinds, PEPFAR is America&’s singular example of how to fight long-term plague—and win. To End a Plague is not merely the definitive history of this extraordinary program; it traces the lives of the activists who first impelled President Bush to take action, and later sought to prevent AIDS deaths at the whims of American politics. Moving from raucous street protests to the marbled halls of Washington and the clinics and homes where Ugandan people living with HIV fight to survive, it reveals an America that was once capable of real and meaningful change—and illuminates imperatives for future pandemic wars. Exhaustively researched and vividly written, this is the true story of an American moonshot.

To Heal Humankind: The Right to Health in History
by Adam GaffneyThe "human right to healthcare" has had a remarkable rise. It is found in numerous international treaties and national constitutions, it is litigated in courtrooms across the globe, it is increasingly the subject of study by scholars across a range of disciplines, and—perhaps most importantly—it serves as an inspiring rallying cry for health justice activists throughout the world. However, though increasingly accepted as a principle, the historical roots of this right remain largely unexplored. To Heal Humankind: The Right to Health in History fills that gap, combining a sweeping historical scope and interdisciplinary synthesis. Beginning with the Age of Antiquity and extending to the Age of Trump, it analyzes how healthcare has been conceived and provided as both a right and a commodity over time and space, examining the key historical and political junctures when the right to healthcare was widened or diminished in nations around the globe. To Heal Humankind will prove indispensable for all those interested in human rights, the history of public health, and the future of healthcare.

To Hell and Back: Personal Experiences of Trauma and How We Recover and Move on
by John MarzillierDespite how rare one-off traumatic events may seem, the statistics show that the majority of us are likely to experience such trauma at some point in our lives. In this innovative and engaging book, Marzillier combines first-hand accounts from trauma sufferers with over forty years of clinical practice to provide an honest, human description of how trauma affects us at the time and also after the event. Whether discussing accounts of terrorist bombings, natural disasters, road accidents or physical attacks, he looks at what these experiences do to us and offers practical and consoling advice - for both sufferers and their loved ones - on coping with the experience and developing resilience for the future.

To Live and To Die: When, Why, and How
by Robert H. WilliamsIn the 1960's marked changes occurred throughout the world in philosophies and policies related to man's role in life. These changes, prompted predominantly by extensive increases in knowledge and popula tion density, have produced increased pleasures as well as problems. The rising number of people and improved methods of communication and transportation have caused more relationships among people, with their pleasures, competitions, jealousies, conflicts of interest, oppressions, and crimes. Large assortments of drugs have been developed and are easily obtained. There are drugs to speed us up, slow us down, make us sleep, change our perspectives on life, promote propagation of life or prevent it, prolong life or terminate it, and modify the course of life in many ways. Also, numerous mechanical devices have been developed that influence the propagation of life, the termination of life, and the manner in which we live. Many people have changed their overall goals in life, and in par ticular have experienced major changes in attitudes and policies applying to sexual activity, marriage, birth control, abortion, welfare, children, old people, criminals, economics, social status, careers, education, euthanasia, and suicide. There also has been marked enlightenment concerning the effect of the chemical and physical status of the brain upon normal and abnormal thinking and behavior.
