Article Synopsis
  • The study investigates whether adding nebulized hypertonic saline (HS) to dornase alfa (DA) treatment improves lung function in cystic fibrosis (CF) patients compared to those receiving DA alone, specifically focusing on F508del homozygous patients.
  • A retrospective analysis of the Cystic Fibrosis Foundation Patient Registry from 2006-2014 included data from 1,241 patients who were treated for 1 to 5 years, analyzing changes in FEV % predicted between the two treatment groups.
  • Results indicated that while patients on DA and HS initially showed lower lung function compared to those on DA only, after adjusting for various factors, their lung function was comparable over time, suggesting that the HS treatment

Introduction: FEV is considered the gold standard spirometric measure for the assessment and management of cystic fibrosis lung disease. Recent evidence suggests that tests at lower lung volumes may be more sensitive.

Objectives: To assess how many other spirometric tests are abnormal in the presence of a normal FEV (≥80%) and which spirometric tests are most sensitive in detecting airway obstruction.

Background: The diagnostic gold standard for neuroendocrine cell hyperplasia of infancy (NEHI) is demonstration of increased numbers of neuroendocrine cells (NECs) amid otherwise near-normal lung histology. Typical clinical and radiographic features often are present. However, NECs are also increased after lung injury and in other disorders, which can complicate biopsy specimen interpretation and diagnosis of suspected NEHI.

This study investigated the efficacy of in-package pasteurization combined with pre-surface application of nisin and/or lysozyme to reduce and prevent the subsequent recovery and growth of Listeria monocytogenes during refrigerated storage on the surface of low-fat turkey bologna. Sterile bologna samples were treated with solutions of nisin (2 mg/ml=5000 AU/ml), lysozyme (10 mg/ml=80 AU/ml) and a mixture of nisin and lysozyme (2 mg nisin+10mg lysozyme/ml) before in-package pasteurization at 65 degrees C for 32s. In-package pasteurization resulted in an immediate 3.

Purpose: Children with cystic fibrosis (CF) have a high prevalence of gastroesophageal reflux disease (GERD). As GERD is associated with chronic respiratory symptoms and feeding problems, fundoplication is often performed in children with CF. Although the outcomes of fundoplication have been described across diverse pediatric groups, there is no published experience with CF.

Cystic fibrosis (CF)-related lung disease is characterized by a broad spectrum of pathologic changes. Most of these changes relate to progressive bronchiectasis and airway destruction due to recurrent infections. Other airway pathologies include but are not limited to nasal polyposis, bronchial hyperactivity, pneumothorax and allergic bronchopulmonary aspergillosis (ABPA).

Rationale: Among young children with cystic fibrosis (CF), Pseudomonas aeruginosa (Pa) airway infection is associated with increased morbidity and mortality. Early intervention strategies include tobramycin solution for inhalation (TSI), which can eradicate lower airway Pa from cultures obtained at the end of 28 days of treatment in young children.

Methods: We conducted an open label, sequential cohort study of TSI in young children with CF to investigate duration of antimicrobial treatment effect.

Barriers to successful outcome for cystic fibrosis (CF) therapies can include distance from a CF care center, co-morbid conditions that require individualized alterations to the prescribed treatment, and patient-provider interactions, among others. We present the case of a 21-month-old female with CF for whom modifications of an efficacious behavioral and nutrition treatment were made due to food allergies and distance from the CF care center. She was classified as at-risk nutritionally.

Early detection and management of pancreatic insufficiency is essential to optimize health and outcomes in cystic fibrosis patients. The gold standard measures for assessment of pancreatic function are direct pancreatic stimulation tests, which have numerous limitations. Estimation of fecal elastase-1 level to determine pancreatic function is an attractive alternative as the test is simple, rapid, cost-effective and easy to perform even in children.
