Pediatric L-HLTx recipients are at risk for developing PTLD with the lung being a primary site of disease. We hypothesized that BALF is a better sample than peripheral blood for measuring EBV DNA load in this high-risk population. Archived BALF specimens from pediatric L-HLTx recipients with and without PTLD were assayed for EBV DNA load using a quantitative real time TaqMan PCR assay.

Experimental traumatic brain injury (TBI) results in marked neurochemical and metabolic changes. Research has demonstrated that after the initial insult the brain undergoes an immediate state of hypermetabolism followed by a sustained period of hypometabolism. The altered extra- and intracellular environment can compromise neuronal performance and limit functional recovery.

Increased use of serial EBV-PCR monitoring after pediatric transplantation has led to the identification of asymptomatic patients who carry very high viral loads over prolonged periods. The significance of this high-load state is unknown. We speculated that this state may identify patients at high risk for development of late PTLD/lymphoma.

Vaccine-preventable diseases remain a major source of morbidity and mortality in transplant recipients. Since the publication of the American Society of Transplantation's guidelines for vaccination of solid organ transplant recipients in 2004 (1), several new vaccines have been licensed. Transplant clinicians have been inundated by questions from patients and colleagues regarding the utility and safety of these vaccines in transplant candidates and recipients.

Lung transplant candidates and recipients are at high risk of infections from vaccine-preventable diseases. However, well-established guidelines neither exist for pre- and post-transplant vaccination nor do monitoring guidelines for pediatric lung transplant recipients. To ascertain the current vaccination and monitoring practices of pediatric lung transplant centers, a self-administered questionnaire was distributed to the 18 pediatric lung transplant centers within the International Pediatric Lung Transplant Collaborative in April 2006.

Congenital cytomegalovirus (CMV) is the most common congenital infection in the USA, affecting approximately 1% of all live births. While the majority of infants will remain asymptomatic, approximately 10% will be symptomatic at birth and another 10-15% will go on to develop problems during the first 6 years of life. Congenital CMV is now the most common cause of nonhereditary sensorineural hearing loss in children.

Background: The cardiovascular safety of mixed amphetamine salts extended release (MAS XR) was evaluated in 2968 children 6-12 years of age with attention-deficit/hyperactivity disorder (ADHD).

Methods: In this prospective, open-label, noncomparative, community-based study, subjects whose symptoms of ADHD were well controlled with stimulant medication maintained their established treatment regimens for 2 weeks before enrollment into the current study. Subjects' regimens were then converted to an approximately equivalent once-daily dose of MAS XR 10, 20, or 30 mg/d according to a medication-conversion algorithm, which could be adjusted to 40 mg/d for optimal efficacy and tolerability.

Despite the progress made in graft and patient survival in recent years, infectious complications remain a major source of morbidity and mortality in pediatric solid organ transplant recipients. The risk of infection after transplant is determined by the interaction of several factors, including age, type of organ transplanted, type and intensity of immunosuppression, environmental exposures, and the consequences of invasive procedures. Compared with adult transplant recipients, children are at higher risk of developing primary infection with various organisms after transplantation, as they often lack previous immunity from natural exposure to many microbes and often have not completed their primary immunization series at the time of transplantation.

Objective: Since the primary hematological complication in both pediatric HIV-1 and malaria is anemia, co-infection with these pathogens may promote life-threatening severe malarial anemia (SMA). The primary objective of the study was to determine if HIV-1 exposure [HIV-1(exp)] and/or HIV-1 infection [HIV-1(+)] increased the prevalence of SMA in children with acute malaria.

Design: The effect of HIV-1 exposure and HIV-1 infection on the prevalence of SMA (hemoglobin < 6.

To study central tolerance to the major product of ongoing apoptosis in the thymus, we made new lines of transgenic (Tg) mice expressing TCR of a pathogenic autoantibody-inducing Th cell that was specific for nucleosomes and its histone peptide H4(71-94). In the lupus-prone (SWR x NZB)F1 (SNF1) thymus, introduction of the lupus TCR transgene caused no deletion, but marked down-regulation of the Tg TCR and up-regulation of endogenous TCRs. Paradoxically, autoimmune disease was suppressed in the alphabetaTCR Tg SNF1 mice with induction of highly potent regulatory T cells in the periphery.

In response to the need for linguistically and culturally appropriate cancer survivorship materials for Latinos, the Office of Education and Special Initiatives and the Office of Cancer Survivorship at the National Cancer Institute (NCI) set out to test, adapt, and refine a Spanish translation of an English-language booklet for adult cancer survivors titled Facing Forward: Life After Cancer Treatment (Siga adelante: la vida después del tratamiento del cáncer). The authors used a process called "transcreation," which involves translating existing English-language materials into Spanish and then adapting them for Latino audiences. The Spanish version of the booklet was reviewed by nine Spanish-speaking reviewers who were cancer survivors.
