The Guest Editors have assembled an international list of top experts to present the most current information to pediatricians about patient safety. The issue has a primarily clinical focus with a few articles addressing the business and practice of patient safety. Articles are devoted to the following topics: Developing performance standards and expectations for safety; The role of CPOE in patient safety; The role of smart infusion pumps on patient safety; Abstracted detection of adverse events in children; The role of effective communication (including handoffs) in patient safety; Reducing mortality resulting from adverse events; Optimizing standardization of case reviews (morbidity and mortality rounds) to promote patient safety; Impact of (resident) duty work hours on patient safety; Role of simulation in safety; The role of diagnostic errors in patient safety; The role of collaborative efforts to reduce hospital acquired conditions; Patient safety in ambulatory care; Role of FDA and pediatric safety; and Patient safety through the eyes of a parent.

The need for safe and effective use of medicines in children and WHO's initiative "Make Medicines Child Size" have boosted research and educational activities in the area of pediatric clinical drug research. This issue focuses on both general and specific aspects of neonatal and pediatric clinical pharmacology including ethics, pharmacogenomics, metabolomics, adverse drug reactions, pain medication, pulmonary hypertension and several other hot topics. The editors have been able to find outstanding authors for the different parts on neonatal and pediatric pharmacology.

Dr. Coppes and his co-Editors have created a comprehensive table of contents that addresses the full spectrum of food allergies in children. Articles are presented to be most useful to pediatricians, as the issue begins with the clinical presentation and epidemiology of food allergy, and then progresses to the diagnostic testing and pahthophysiology. Articles are also included that are devoted to specific types of food allergy, dairy, soy, egg, peanut, and tree nut. Finally, articles are also devoted to living with food allergies, management of allergies in schools and camps, and therapies for food allergies.

The subject of Pediatric Bone Marrow Transplantation is reviewed in this issue of Pediatric Clinics. Guest Editors Drs. Max Coppes, Terry Fry, and Crystal Mackall have assembled a panel of experts who offer reviews on topics including Allogeneic BMT for leukemia, GVL in pediatric leukemia, Stem cell source and outcome following BMT in children, Acute GVHD in children, Chronic GVHD in children, BMT for Hemoglobinopathies, BMT for immunodeficiency, BMT for rheumatologic disorders and other benign diseases, Autologous and Allogeneic BMT for solid tumors, Late effects following BMT, Cell therapies/vaccines for malignancy and infections, BMT for metabolic disorders, BMT for bone marrow failure syndromes, and Immunotherapy in the context of SCT.

This issue highlights some of the exciting new developments in pediatric oncology and hematology. Three articles are devoted to pediatric leukemia, which remains the most common form of pediatric cancer. Specifically, articles address ALL, AML, and leukemia in patients with Down syndrome. Other articles that address pediatric oncology include CNS tumors and neuroblastoma as well as advances in cancer immunotherapy. A very interesting article addresses the challenges experienced by adults who survived a childhood cancer. The hematology articles in this issue cover aspects that most clinicians see on a regular basis-sickle cell disease, thalassemia, and hemophilia, and ITP.
