Glycemic control and FEV recovery during pulmonary exacerbations in pediatric cystic fibrosis-related diabetes.

Rationale: Whether short-term glucose control in cystic fibrosis-related diabetes (CFRD) is associated with FEV recovery during acute pulmonary exacerbations is unclear.

Methods: Data from all patients with CFRD ages 6-21 years hospitalized in 2010-2016 for pulmonary exacerbations at our CF Center were analyzed, including CFRD status at each encounter, all FEV recorded during each exacerbation, and relevant clinical covariates. Glucose control was analyzed using meter blood glucose area under the curve (AUC) indices.

The effects of high-frequency chest compression on end-tidal CO.

Introduction: High-frequency chest compression (HFCC) is used for airway clearance, but may have other effects. We sought to determine if HFCC provides augmented ventilation.

Methods: During treatment, capnometry was measured with the HFCC vest set to 6-20 Hz.

Subjective and Objective Assessments of Flow-Volume Curve Configuration in Children and Young Adults.

Rationale: Analysis of maximal expiratory flow-volume curves (MEFVCs) allows for determination of airway obstruction, but quantitative methods to describe these curves are not commonly used.

Objectives: We sought to determine the variability in MEFVC concavity assessment by pulmonary physicians, whether objective indices of concavity can be substituted for subjective expert impression, and whether MEFVC concavity correlates with clinical outcomes.

Methods: A survey of 37 MEFVCs (plus 3 duplicates) was sent to pulmonologists for quantitative assessment of MEFVC concavity.

Effects of load and indicator type upon occlusal contact markings.

Statement Of Problem: Clinicians use occlusal indicators to identify tooth contacts. However, the reliability of these indicators has been questioned. At times occlusal contacts are not identified or false positive occlusal contacts are observed.

Long-term effects of storage and thermal cycling on the marginal adaptation of provisional resin crowns: a pilot study.

Statement Of Problem: Provisional resin crowns may be used for an extended period while complex treatments are completed. The crowns function intraorally; therefore, moisture absorption and thermal cycling may affect the physical properties of acrylic resin, causing a change in marginal gap size.

Purpose: The purpose of this pilot study was to examine the effect of long-term water absorption and thermal cycling on marginal gap size of polymethyl methacrylate copolymer and bis-acrylic composite resin crowns.
