Principles and Practice of Cancer Infectious Diseases is a comprehensive and insightful work dedicated to elucidating the problem of infections in cancer patients. This essential volume reviews common and less often encountered infections, while establishing the difficulties behind preventing, diagnosing, and treating infectious diseases in cancer patients. Key sections are devoted to the presentation of clinical symptoms and the identification of major etiologic agents. A cadre of leading clinicians provide a detailed assessment of the risk factors for various infections, critical strategies in preventing and managing infections, and study of the interactions between the pathogen and host's immune function and inflammatory response. With its in-depth knowledge and concise treatment of the distinct facets of infections in cancer patients, this volume is an indispensible tool for all infectious disease specialists and clinical oncologists.

Pediatricians in the Unites States and around the World continue to face a myriad of global health threats affecting child and adolescent health including: 1) infectious diseases of poverty [e.g. human immunodeficiency virus (HIV), tuberculosis, malaria, and neglected tropical diseases] in low-and middle-income countries (LMIC), especially in sub Saharan Africa; 2) emerging and reemerging infectious diseases (such as Ebola); 3) rise of non-communicable diseases (e.g. common mental disorders); 4) unintentional injuries; and 5) environmental health hazards (e.g. climate change). Despite the promising news about rapid declines in maternal and child mortality in the era of Millennium Development Goals (MDGs), which originated from the United Nation (UN) Millennium Declaration in 2000, only 20% and 7% of LMIC are currently on track to attain the maternal and child mortality targets. For example, 44% of deaths in children younger than 5 years occur in neonates. Besides discovery of life-saving interventions (e.g. development of new and improved vaccines) for maternal and child health, we also need to do a better job at bridging the knowledge-implementation gap and increase the effectiveness of proven interventions. For example, despite the availability of effective vaccines to prevent pneumococcal pneumonia, rotavirus gastroenteritis, and human papilloma virus-related diseases (e.g. cervical cancer), use of these vaccines remain suboptimal in LMIC. We need to recognize that global health is also local public health. For example, improving access, equity and quality of care for orphans and vulnerable children, immigrant and newly arrived refugee children in the U.S. remains a challenge. Timely access to psychiatric care for children and adolescents with mental illness is a major concern. The explosion of new age technology (such as the internet) also poses a considerable risk to children and adolescents. Pediatricians also need to be aware of diverse socio-cultural determinants of health and ethical issues in global health service and delivery. This issue of Pediatric Clinics of North America aims to address the above crucial global health challenges affecting children and adolescents. As practicing pediatricians, we have the unique opportunity to influence local and global public health. In the post-MDG era (beyond 2015), collaborative partnerships between various disciplines and across research, education and service is vital to reduce health inequities in children worldwide.

With advances in technology and medical science, children with previously untreatable and often fatal conditions, such as congenital heart disease, extreme prematurity and pediatric malignancy, are living longer. While this is a tremendous achievement, pediatric providers are now more commonly facing challenges in these medical complex children both as a consequence of their underlying disease and the delivery of medical care. The term healthcare-associated infections (HAIs) encompass both infections that occur in the hospital and those that occur as a consequence of healthcare exposure and medical complexity in the outpatient setting. HAIs are associated with substantial morbidity and mortality for the individual patient as well as seriously taxing the healthcare system as a whole. In studies from the early 2000s, over 11% of all children in pediatric intensive care units develop HAIs and this figure increases substantially if neonatal intensive care units are considered. While progress has been made in decreasing the rates of HAI in the hospital, these infections remain a major burden on the medical system. In a study published in 2013, the annual estimated costs of the five most common HAIs in the United States totaled $9.8 billion. An estimated 648,000 patients developed HAIs in hospitals within the US in 2011 and children with healthcare-associated bloodstream infection have a greater than three-fold increased risk of death. While a number of texts discuss HAIs in the broader context of infectious diseases or pediatric infectious diseases (such as Mandell’s Principles and Practice of Infectious Diseases or Long and Pickering’s Principles and Practice of Pediatric Infectious Diseases) no single text specifically focuses on the epidemiology, diagnosis and management of HAI in children. Many infectious diseases texts are organized based on the microbiology of infection and from this starting point then discussing the clinical syndromes associated with the organism of interest. For instance, a chapter on Staphylococcus aureus may contain a brief discussion of the role of S. aureus in surgical site infections in the wider context of all staphylococcal disease. For clinicians caring for children at the bedside, however, the clinical syndrome is typically appreciated and intervention necessary prior to organism identification. We propose a text that details both the general principles involved in HAIs and infection prevention but also provides a problem oriented approach. Such a text would be of interest to intensivists, neonatologists, hospitalists, oncologists, infection preventionists and infectious diseases specialists. The proposed text will be divided into three principle sections: 1) Basic Principles of Infection Control and Prevention, 2) Major Infectious Syndromes and 3) Infections in Vulnerable Hosts. Chapters in the Major Infectious Syndromes section will include discussion of the epidemiology, microbiology, clinical features, diagnosis, medical management (or surgical management as appropriate) and prevention of the disease entity of interest. Chapters will seek to be evidenced based as much as possible drawing from the published medical literature as well as from clinical practice guidelines (such as those from the Infectious Diseases Society of America) when applicable. We intend to include tables, figures and algorithms as appropriate to assist clinicians in the evaluation and management of these often complex patients. Finally, we intend to invite authors to participate in this project from across a number of medical specialties including infectious diseases, infection control, critical care, oncology and surgery to provide a multidisciplinary understanding of disease. It is our intent to have many chapters be co-written by individuals in different subspecialties; for instance, a chapter on ventilator-associated pneumonia may be co-written by both infectious disease and critical care medicine specialists. Such a unique text has the potential to provide important guidance for clinicians caring for these often fragile children.

With the fall in mortality from infectious diseases, the· impact of childhood cancer in the Western World has increased to become the second commonest cause of death in the age group 1-14 years, being surpassed only by accidents. However, even in those countries in which paediatric cancer is attracting increasing interest, the disease is relatively uncommon, and the number of cases seen by any one physician, even in a large general hospital, is often limited to one or two a year. The widely held view by parents and even by many doctors that cancer in childhood is usually untreatable and inevitably fatal is no longer tenable. With improvement in the therapeutic response or in the actual survival rates of children with such lesions as Wilms' tumour, brain tumours, rhabdomyosarcomas, Ewing's sarcoma, retinoblastoma, lym phoma and even leukaemia, there is a real hope of achieving a substantial reduction in the mortality of childhood cancer. Paediatric oncology is, in fact, providing a vigorous stimulus to the much wider field of cancer treatment and research, and is demonstrating the advantages of a multi-disciplinary cooperation in the management of this disease.
