Abstract
BACKGROUND Hematopoietic stem cell transplantation, despite being a curative treatment for various pediatric disorders, is associated with significant acute and chronic complications. METHODS This retrospective review of 196 hematopoietic stem cell transplantation episodes (144 allogeneic, 52 autologous) performed in a tertiary pediatric unit focused on neurological symptoms and complications occurred from the start of conditioning to within 3 years of transplantation. Indications for transplantation included both benign and malignant diseases. For episodes involving allogeneic transplantation, 42% of donors were matched-unrelated, 19% were matched-sibling, and 12% were haploidentical. RESULTS: Neurological complications developed in 17% of all hematopoietic stem cell transplantation episodes. Tumors of central nervous system and leukemia or lymphoma were two indications reported to have higher incidence of 42% and 21%, respectively. The occurrence of neurological complications was significantly associated with primary diagnosis (p = 0.01), central nervous system involvement by underlying disease (p = 0.001), and radiation-based conditioning (p = 0.018). Upon multivariate analysis, central nervous system involvement by underlying disease remained to be the only significant factor (p = 0.019), while radiation-based containing conditioning (p = 0.029) is revealed to be associated when considering allogeneic transplantation alone. Pre-transplant central nervous system-directed treatment, allogeneic versus autologous donor, stem cell source, donor type, busulfan use, and cyclosporin use were not significantly associated with neurological complications. Patients with neurological complications were also found to have an inferior 2-year overall survival (53.9% ± 8.8% versus 63.8% ± 4.2%; p = 0.016). CONCLUSION Neurological complications were common in pediatric hematopoietic stem cell transplantation and were associated with adverse outcome; non-radiation containing conditioning regimens might be beneficial in mitigating the risk of such complications.

Abstract
HSCT is an established treatment option for some children with life-threatening diseases, but complications remain a major cause of morbidity and mortality. This retrospective data analysis addresses the surgical issues of children with HSCT-related complications. Between 2002 and 2008, HSCT was performed in 240 children for leukemias/lymphomas (n=135), solid tumors (n=59), immunodeficiencies (n=20), lipid storage diseases (n=10), autoimmune diseases (n=9), and others (n=7). HSCT-related complications requiring surgery occurred in 24 cases (10%) and most often in the leukemias/lymphomas group (18/24 cases): HC (cystoscopic irrigation, n=7), pulmonary aspergilloses (resection, n=7), bone necroses (core decompression, n=3), GvHD bowel (colostomy/PEG, n=2), ICH (drainage, n=2), bilateral kidney abscess (nephrectomies/renal transplantation, n=1), aspergillosis of the maxillary sinus (decompression, n=1), and post-traumatic wound healing disorder (meshed skin transplantation, n=1). Survival was 50% in the group with surgery and 62% in the group without (p=0.275). Even though this difference was not statistically significant, surgical intervention should be encouraged in all cases to achieve favorable results.

Abstract
Hematopoietic stem cell transplantation (HSCT) is used to treat an expanding array of malignant and non-malignant disorders. Pulmonary complications represent a significant source of morbidity and mortality in HSCT recipients. Young children, whose lungs are still developing and growing, may be especially susceptible to the insults of irradiation, drug toxicities, and recurrent infections associated with immunosuppression. Late pulmonary complications, those occurring more than three months after transplantation, are often noninfectious and present with nonspecific symptomatology. Pulmonary function testing (PFT) is a mainstay of monitoring pulmonary health in HSCT recipients. The pulmonologist should be familiar with common patterns seen on PFT in recipients of HSCT during childhood. In this review, we describe the findings in studies which have examined lung function over time in patients who underwent HSCT during childhood. We discuss patterns of PFT abnormalities, associated noninfectious syndromes and their clinical implications, as well as directions for future research.
