There have been major advances in new therapies, diagnostic tools, and strategies for treatment and prevention of fungal infections. Despite these encouraging developments, large numbers of patients are at risk for infectious diseases, and the epidemiology of invasive mycoses continues to emerge. The diagnosis of these infections remains difficult, and treatment outcomes in highly immunosuppressed patients remain poor. Thus, this issue is devoted to state-of-the-art updates on fungal infections by internationally recognized authorities in this field. Some topics covered are Antifungal agents; State-of-the-art culture, identification, and resistance testing of fungal pathogens; Non-culture diagnostics in fungal disease; Contemporary strategies in the prevention and management of fungal infections; Invasive candidiasis; Invasive aspergillosis; Mucormycoses; and Cryptococcosis to name a few.

In this issue, guest editors bring their considerable expertise to this important topic.Provides in-depth reviews on the latest updates in the field, providing actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create these timely topic-based reviews.

Children in developing countries continue to be susceptible to infectious and non-infectious disorders that lead to growth retardation, cognitive impairment and high infant and childhood mortality. Clinical, epidemiologic and pathogenetic studies are providing opportunities to intervene against these disorders as never before. In this issue, international experts in child health offer their perspectives on the problems of greatest import to the health of children growing up in impoverished environments. Opportunities for research and intervention are particularly emphasized. Articles are specifically devoted to the following topics: Child Health and Survival in a Changing World; Childhood Nutrition and Growth; Children with Disabilities in the Developing Nations; The Burden of Enteropathy and Subclinical Infections; Malaria in Children; The Unholy Trinity: Nematode Infections in Developing Countries; The Burden and Etiology of Diarrheal Illness in Developing Countries; Intestinal Protozoal Infections; Pneumonia and Respiratory Infections; Primary Bacteremia and Meningitis in Developing Countries; Neonatal and Perinatal Infections; HIV in Developing Countries; and Tuberculosis in Children.

For many years, physicians and the public assumed that the discovery of new antimicrobial agents would outpace the ability of bacteria to mutate and develop drug resistance. Yet the development of new antibiotics has not kept up with bacterial evolution, especially since the late 1990’s. At that time a multitude of pharmaceutical companies abandoned antibiotic research because of strong economic disincentives. For example, it is challenging for these companies to recuperate the investment (typically in the hundreds of millions of dollars) made in developing a new antibiotic, which is typically prescribed for a few days, compared to drugs that treat chronic conditions like heart disease or mental illness. This situation has led the U.S. federal government to take a more active lead in addressing antibiotic resistance. Recently, the White House announced an action plan that includes improving surveillance, developing better diagnostic tools, accelerating drug development, and improving global coordination of antibiotic resistance issues. Equally important is the $1.2 billion dollars that has been pledged to fund these efforts. While we await the implementation of new policies, this issue of Infectious Disease Clinics of North America brings together leading authorities in the field of antibiotic resistance who discuss current issues including antibiotic stewardship, the changing role of the microbiology laboratory in determining antibiotic resistance in gram-negative pathogens, the continuing spread of metallo-ß-lactamases, ESBLs and KPCs, antibiotic options for treating resistant gram-negative infections such as colistin and tigecycline, resistance mechanisms and new treatment options for Mycobacterium tuberculosis, emerging resistance mechanisms in aminoglycosides, issues with antibiotic resistance in immunocompromised patients, new ß-lactamase inhibitors in the clinic, and resistance in VRE and Staphylococcus aureus. Additionally, combination therapy for resistant gram-negative infections has been advocated by some authorities and the advantages and disadvantages of this strategy will be reviewed.

This second part of a 2-part issue of Infectious Disease Clinics, edited by Michael S. Saag, MD and Henry Masur, MD, is devoted to HIV/AIDS. This issue will address the prevention of HIV/AIDS with topics such as: Mother to Child Transmission; Treatment as Prevention; Barrier and Microbicides; Prevention of HIV/AIDS: Pre-exposure Prophylaxis; Post-Exposure Prophylaxis; HIV Vaccine, and a final article addressing the cure of HIV/AIDS.
