Abstract
Pediatric lung transplantation is a highly specialized treatment option at a select few hospitals caring for children. Advancements in surgical and medical approaches in the care of these children have improved their care with only minimal improvement in outcomes which remain the lowest of all solid organ transplants. A crucial time period in the management of these children is in the perioperative period after performance of the lung transplant. Supporting allograft function, preventing infection, maintaining fluid balance, achieving pain control, and providing optimal respiratory support are all key factors required for this highly complex pediatric patient population. We review commonly encountered complications that these patients often experience and provide strategies for management.

Abstract
In a retrospective, single-center cohort study, outcomes of infants and toddlers undergoing lung transplant at St. Louis Children's Hospital between 1990 and 2004 were compared to older children. Patients with cystic fibrosis (exclusively older children) and those who underwent heart-lung, liver-lung, single lung or a second transplantation were excluded from comparisons. One hundred nine lung transplants were compared. Thirty-six were in infants <1 year old, 26 in toddlers 1-3 years old and 47 in children >3 years old. Graft survival was similar for infants and toddlers (p = 0.35 and p = 0.3, respectively) compared to children over 3 years old at 1 and 3 years after transplant. Significantly more infants (p < 0.0001 and p = 0.003) and toddlers (p = 0.002 and p = 0.03) were free from acute rejection and bronchiolitis obliterans compared to older patients. While most infants and toddlers had only minimal lung function impairment, and achieved normal to mildly delayed developmental scores, somatic growth remained depressed 5 years after transplant. Lung transplantation in infants and young children carries similar survival rates to older children and adults. Further insights into the unique immunologic aspects of this group of patients may elucidate strategies to prevent acute and chronic rejection in all age groups.

Abstract
OBJECTIVE To describe the results of lung transplantation (LTx) in adolescents at a hospital for adults. DESIGN AND SETTING Prospective cohort study set in an LTx unit at an adult tertiary referral hospital from 1991 to 2006. PATIENTS 37 consecutive adolescent lung transplant recipients including 13 males and 24 females (mean age, 16.7+/-2.0 [SD] years; range 12-19 years) who received heart-lung (six patients) or bilateral LTx (31 patients) for cystic fibrosis (29), congenital heart disease (four), acute respiratory failure (two), or another disorder (two). Two patients were transplanted after invasive ventilation, five after non-invasive ventilation and two after extracorporeal membrane oxygenation. MAIN OUTCOME MEASURES Overall survival compared with an adult cohort; survival free of bronchiolitis obliterans syndrome (BOS); overall and BOS-free survival in those transplanted before and after January 2000. RESULTS Mean waiting time was 273 days (range, 5-964 days; median, 163 days), mean donor age was 28 years (range, 9-53 years). Median inpatient stay was 11 days (range, 7-94 days). Mean follow-up was 1540+/-1357 days (range, 35-5163 days). The 5-year survival rate for the 16 patients transplanted before January 2000 was 38%, versus 74% for the 21 transplanted since January 2000 (P=0.05; Mantel-Cox). Overall, 18 of 35 evaluable patients developed BOS. Only BOS was associated with an increased mortality risk (P<0.01). CONCLUSION LTx may be performed successfully in adolescents at a hospital for adults.

Abstract
BACKGROUND Although new approaches to the treatment of patients with cystic fibrosis (CF) are significantly prolonging their lives, most patients will eventually develop respiratory failure due to progressive bronchiectasis caused by chronic lung infection and inflammation and die from to respiratory failure. We examined our center's (University of Wisconsin Hospital and Clinics) experience with lung transplantation for patients with CF and reviewed the literature to examine current and evolving approaches to transplantation for this indication. METHODS We reviewed all published literature pertaining to lung transplantation for CF through 2006, and we reviewed all aspects of transplantation for patients with CF at our institution from 1994 to 2005. RESULTS Major complications following lung transplantation include acute rejection, bacterial infection, and bronchiolitis obliterans. Five-year survival at UWHC (Kaplan-Meier) is 67%, and survival was not adversely affected by transplanting patients receiving mechanical ventilation. The major cause of death for transplant recipients was bronchiolitis obliterans syndrome (BOS). CONCLUSIONS Lung transplantation for CF is associated with acceptable survival rates and can improve quality of life. Lung transplant should be offered to all patients with advanced CF lung disease if they meet currently accepted inclusion and exclusion criteria.

Abstract
Solid organ transplantation is accepted as a standard lifesaving therapy for end-stage organ failure in children. This article reviews trends in pediatric transplantation from 1996 to 2005 using OPTN data analyzed by the Scientific Registry of Transplant Recipients. Over this period, children have contributed significantly to the donor pool, and although the number of pediatric donors has fallen from 1062 to 900, this still accounts for 12% of all deceased donors. In 2005, 2% of 89,884 candidates listed for transplantation were less than 18 years old; in 2005, 1955 children, or 7% of 28,105 recipients, received a transplant. Improvement in waiting list mortality is documented for most organs, but pretransplant mortality, especially among the youngest children, remains a concern. Posttransplant survival for both patients and allografts similarly has shown improvement throughout the period; in most cases, survival is as good as or better than that seen in adults. Examination of immunosuppressive practices shows an increasing tendency across organs toward tacrolimus-based regimens. In addition, use of induction immunotherapy in the form of anti-lymphocyte antibody preparations, especially the interleukin-2 receptor antagonists, has increased steadily. Despite documented advances in care and outcomes for children undergoing transplantation, several considerations remain that require attention as we attempt to optimize transplant management.

Abstract
Bilevel positive airway pressure ventilation (BIPAP) has been used in cystic fibrosis (CF) patients as a bridge to transplantation. Our aim was to evaluate the effect of BIPAP use before transplantation on post-transplantation morbidity and mortality. We performed a retrospective study at a tertiary care center. Twelve CF patients (9 males; mean age = 26 years) were assessed. Group 1 consisted of eight patients that did not use BIPAP before lung transplantation. Group 2 comprised four patients who used BIPAP for 3-15 months while awaiting transplantation. Patients were evaluated before and two to ten years after transplantation. All eight patients who did not use BIPAP died two months to ten years after transplantation. All four BIPAP users are alive with no evidence of bronchiolitis obliterans two to eight years after lung transplantation. We demonstrated a significant improvement in acid-base balance (p < 0.01) and body mass index (p < 0.05) and a tendency toward improvement in the work of breathing and number of hospitalizations. We conclude that improvement in nutritional status and respiratory muscle strength before lung transplantation in BIPAP users may prevent post lung transplantation infection and acute rejection rate, which in turn may reduce chronic rejection (bronchiolitis obliterans) and improve long-term survival after lung transplantation.

Abstract
The pulmonary surfactant is a mixture of phospholipids and proteins synthesized, packaged, and secreted by alveolar type II cells that lowers surface tension and prevents atelectasis at end-expiration. A tightly regulated, complex metabolic cycle involves all components of the pulmonary surfactant. Disorders of surfactant metabolism that have a genetic basis are rare, but causes of respiratory dysfunction in infants and children emerge. Recessive loss of function mutations in surfactant protein-B (SP-B) gene lead to respiratory failure that is lethal in the newborn period while single allelic mutations in the surfactant protein-C (SP-C) gene cause interstitial lung disease of varying severity and age of onset. The genetic basis, mechanisms, clinical presentation and outcome, diagnostic approach and limited therapeutic options for disease due to mutations the SP-B and SP-C genes will be described in detail in this article. These disorders provide insights into some of the distinct mechanisms that disrupt the surfactant metabolic cycle and cause respiratory disease in infants and children.

Abstract
OBJECTIVE To determine if the outcomes of lung transplantation for infants with surfactant protein-B (SP-B) deficiency are unique. STUDY DESIGN From a prospective analysis to identify infants with genetic causes of surfactant deficiency, we identified 33 SP-B-deficient infants from 1993 to 2005, and, among those undergoing lung transplantation (n = 13), compared their survival, pulmonary function, and developmental progress with infants who underwent transplantation at <1 year of age for parenchymal lung disease (n = 13) or pulmonary vascular disease (n = 11). RESULTS Five-year survival rates ( approximately 50%, P = .3) and causes of death were similar for all three groups once the infants underwent transplantation. However, significant pretransplantation mortality decreased 5-year survival from listing to approximately 30% (P = .17). Pulmonary function, development of bronchiolitis obliterans, and school readiness were similar among the three groups. We detected anti SP-B antibody in serum of 3 of 7 SP-B-deficient infants and none of 7 SP-B-sufficient infants but could not identify any associated adverse outcomes. CONCLUSIONS Long-term outcomes after infant lung transplantation for SP-B-deficient infants are similar to those of infants transplanted for other indications. These outcomes are important considerations in deciding to pursue lung transplantation for infants with disorders of alveolar homeostasis.

Abstract
Since the original description of deficiency of the pulmonary surfactant in premature newborn infants by Avery and Mead in 1959, respiratory distress syndrome has most commonly been attributed to developmental immaturity of surfactant production. Studies of different ethnic groups, gender, targeted gene ablation in murine lineages, and recent clinical reports of monogenic causes of neonatal respiratory distress syndrome have demonstrated that genetic defects disrupt pulmonary surfactant metabolism and cause respiratory distress syndrome, especially in term or near-term infants and in older infants, children, and adults. In contrast to developmental causes of respiratory distress, which may improve as infants and children mature, genetic causes result in both acute and chronic (and potentially irreversible) respiratory failure.

Abstract
During the past two decades, several advances have resulted in marked improvement in medium-term survival for infants and children undergoing heart transplantation. Unfortunately, progress has been less dramatic in the field of lung and heart-lung transplantation, where there is little evidence of improved outcomes. The procedures remain palliative and all transplant recipients are at risk for the adverse effects of non-specific immunosuppression, including infections, lymphoproliferative disorders, and non-lymphoid malignancies. In addition, current immunosuppressive agents have narrow therapeutic windows and exhibit a wide array of organ toxicities, posing special challenges for the young patient who must endure life-long immunosuppression. New immunosuppressive regimens have lowered the rates of acute rejection but appear to have had relatively little impact on the incidence of chronic rejection, the principal cause of late graft loss. The ultimate goal is to induce a state of donor-specific tolerance, wherein the recipient will accept the allograft indefinitely without the need for long-term immunosuppression. This quest is currently being realised in animal models of solid organ transplantation, and offers great hope for children undergoing heart and lung transplantation in the future.

Abstract
Critical care medicine developed out of other subspecialties' need to provide care for their most critically ill patients. Advanced technologies, the understanding of the pathophysiology of critical illness, and the development of the multidisciplinary team have made this care possible. Pediatric critical care medicine emerged in the 1960s and has expanded dramatically since then. The field has made major advances in the areas of lung injury, sepsis, traumatic brain injury, and postoperative care. We review here the evolution of modern pediatric critical care medicine from its roots in general pediatric and cardiac surgery, adult respiratory care medicine, neonatology, and pediatric anesthesiology to its current state as a unique discipline.

Abstract
Solid organ transplantation has become accepted therapy for the treatment of end-stage organ dysfunction in children. As early management of the pediatric transplant recipient has improved, important age-related differences in long-term patient outcomes have become apparent. Late morbidity and mortality can, in most cases, be attributed to the consequences of long-term immunosuppression: graft loss from under-immunosuppression or an increased incidence of cancer, hypertension, renal failure or diabetes from over-immunosuppression. Age-related differences in both biological and psychological factors play an important role in the optimization of therapy in the transplanted child. Important age-related differences have been demonstrated in all phases of pharmacokinetics: absorption, distribution, metabolism and elimination. Information regarding specific age-related pharmacokinetic differences is lacking for many immunosuppressive medications. Further study using physiologically based pharmacokinetic (PBPK) models will lead to more specific recommendations for age-based immunosuppression protocols. Non-adherence is common among solid organ transplant recipients of all ages and the consequences of non-adherence include increased rejection, late graft loss and death. The biological and psychological developmental changes that occur during adolescence place the transplanted adolescent at an even higher risk of non-adherence and poor outcome than other age groups. Further studies to elucidate the importance of both age-related pharmacokinetic and behavioral factors are needed to formulate therapeutic interventions that would improve adherence and patient outcomes.

Abstract
Interstitial lung disease includes a group of chronic diseases characterized by alterations in alveolar walls and loss of functional alveolar-capillary units. These are rare diseases in children, mostly with an unknown cause and associated with a high morbidity and mortality due to insufficient therapeutic effectiveness. The authors report a case of a previously healthy 3 years old child who presented with wheezing and severe respiratory insufficiency following a respiratory infection. The investigation performed led to the diagnosis of chronic interstitial pneumonitis. Several treatments have been tried (corticosteroids, hydroxychloroquine, N-acetylcysteine) without any obvious improvement.
