    High incidence of fracture events in patients with Long-Gap Esophageal Atresia (LGEA): A retrospective review prompting implementation of standardized protocol☆
    (Elsevier, 2015) Bairdain, Sigrid; Dodson, Brenda; Zurakowski, David; Rhein, Lawrence; Snyder, Brian; Putman, Melissa; Jennings, Russell
    Purpose To identify factors associated with an increased risk of fractures in Long-Gap Esophageal Atresia (LGEA) patients. Following implementation of a risk-stratified program, we hypothesized a reduction in fracture incidence within this potentially high-risk population. Methods: A retrospective review of LGEA-patients admitted between 2005 and 2014 was conducted. Symptomatic fractures with radiographic confirmation were defined as events. Univariate and multivariable analysis evaluated factors including admission weight-for-age z-score, primary versus secondary Foker process (FP), weight at Foker Stage I, days and episodes of paralysis, number of parenteral nutrition (PN) days, cumulative dose of loop diuretics adjusted for body weight and days exposed, and exposure to non-loop diuretics. A fracture-prevention protocol was initiated in 2012; incidence was evaluated pre and post-intervention. Results: Fifty-nine patients met inclusion criteria. Twenty-three (39%) patients in the entire cohort incurred at least one fracture during their hospitalization utilizing the Foker process. Given this high percentage, a targeted fracture-prevention protocol was initiated in 2012. Fracture incidence decreased from 48% prior to the protocol to 21% following the protocol (P = 0.046). Several variables that were associated with an increased risk of fractures on univariate analysis included prior esophageal anastomosis attempt (P = 0.008), number of separate episodes of paralysis (P = 0.002), exposure to non-loop diuretics (P = 0.006), cumulative loop diuretic dose (P < 0.001), as well as cumulative loop diuretic over days exposed (P < 0.001). Intensive care unit (ICU) stay (P = 0.002) and total length of hospitalization (P < 0.001) were also significantly longer among patients with a fracture. Number of separate episodes of paralysis was the only independent risk factor for the development of a fracture; patients having more than 3 episodes of paralysis had an estimated risk of fracture 15 times higher than those patients paralyzed only once or twice (O.R. 15.87, 95% C.I.: 1.47–171.23, P = 0.008). Conclusion: Episodes of paralysis appeared to be the most significant risk factor for fractures in patients with LGEA who underwent the Foker procedure. The incidence of symptomatic fractures decreased significantly following implementation of a standardized protocol in this series of LGEA patients with continued prospective evaluation.

    Cystic Fibrosis Related Bone Disease
    (2015-05-20) Putman, Melissa; Finkelstein, Joel S.; Bouxsein, Mary L.; Yu, Elaine W.; Conlin, Paul
    Over the past several decades, life expectancy for patients with cystic fibrosis (CF) has increased significantly. As patients live longer, other nonpulmonary co-morbidities related to CF have become increasingly prevalent, including CF-related bone disease. Because CF related bone disease has only recently emerged as a clinical problem, and the underlying bone alterations and pathogenesis of this condition have not been established. This thesis explores the underlying bone micro-architecture and strength alterations found in adults with CF using state-of-the-art bone imaging techniques and explores whether improvements in the treatment of patients with CF over the past 15 years has led to similar improvements in bone health.
