OBJECTIVE To characterize the medical history, disease progression, and treatment of current-era patients with the rare diseases Fontan-associated protein-losing enteropathy (PLE) and plastic bronchitis. STUDY DESIGN A novel survey that queried demographics, medical details, and treatment information was piloted and placed online via a Facebook portal,(More)
Pediatric pharmacotherapy is often challenging due to the paucity of available clinical data on the safety and efficacy of drugs that are commonly used in children. This quandary is even more prevalent in children with rare diseases. Although extrapolations for dosing and administration are often made from available adult data with similar disease states,(More)
Plastic bronchitis (PB) is a rare disease that often occurs in patients with congenital heart disease (CHD) who have undergone staged single-ventricle palliation. It is characterized by the formation of rubbery “casts” in the airways. PB treatment frequently includes inhaled tissue plasminogen activator (tPA). However, the efficacy of tPA to reduce cast(More)
For pediatric rare diseases, the number of patients available to support traditional research methods is often inadequate. However, patients who have similar diseases cluster "virtually" online via social media. This study aimed to (1) determine whether patients who have the rare diseases Fontan-associated protein losing enteropathy (PLE) and plastic(More)
PURPOSE In an effort to minimize barriers to compliance and adherence and to improve the accuracy of dosage measurement, sugar-containing and sugar-free sodium phenylbutyrate suspensions were formulated, and the stability of these products over a 90-day period was determined. METHODS An oral suspension of sodium phenylbutyrate 200 mg/mL was prepared by(More)
Plastic bronchitis (PB) is a poorly understood disease that can complicate any underlying pulmonary disease. However, it appears to most often occur in patients with surgically palliated congenital heart disease, particularly after the Fontan procedure. Few data exist about the prevalence and etiology of PB in this population. In an effort to establish data(More)
PURPOSE The stability of an extemporaneously prepared tadalafil oral suspension was studied. METHODS An oral suspension of tadalafil 5 mg/mL was prepared by thoroughly grinding 15 20-mg tadalafil tablets in a glass mortar. Thirty milliliters of Ora-Plus and 30 mL of Ora-Sweet were mixed and added to the powder to make a final volume of 60 mL. Three(More)
PURPOSE The stability of an extemporaneously prepared clopidogrel oral suspension was studied. Methods Clopidogrel oral suspension (5 mg/mL) was prepared using clopidogrel bisulfate tablets, Ora-Plus, and Ora-Sweet. Six 2-oz samples were prepared; three were stored at room temperature and three under refrigeration. One milliliter was withdrawn from each(More)
Inhaled nitric oxide (iNO) is considered standard therapy for pediatric postcardiac surgical pulmonary hypertension (PH). Limited data suggest that inhaled iloprost (inIlo), an aerosolized prostacyclin, may be a feasible and more affordable therapeutic alternative. The goal of this study was to determine if significant hemodynamic change or adverse events(More)
