Diagnostic challenges in CFTR-related metabolic syndrome: Where the guidelines fall short.

Newborn screening (NBS) for cystic fibrosis (CF) has enabled earlier diagnosis and has improved nutritional and growth-related outcomes in children with CF. For those with a positive NBS for CF that do not meet the diagnostic criteria for CF, the clinical entity called CFTR-Related Metabolic Syndrome (CRMS) or CF Screen- Positive, Inconclusive Diagnosis (CFSPID) is used. Although most children with CRMS remain relatively asymptomatic, studies have shown that between 11% and 48% of these patients may eventually progress to a diagnosis of CF over time.

Outpatient Utilization of the RAM Cannula for Nasal Noninvasive Ventilation in Children.

Background: The RAM cannula consists of nasal prongs that can be used to administer oxygen, continuous, and bilevel positive airway pressure therapies. Studies have reported the efficacy and utility of the RAM cannula in inpatients requiring noninvasive ventilation (NIV); however, there is limited literature on the use of the RAM cannula to provide NIV in the outpatient setting.

Objectives: This study aimed to describe the clinical features and outcomes of children who used NIV via RAM cannula in the outpatient setting.

Bronchoscopic interventions for plastic bronchitis in children without structural heart disease.

Plastic bronchitis (PB) is a rare and life-threatening complication encountered in several disease states that leads to airway obstruction by branching casts. PB is most often reported in children with cyanotic congenital heart disease where recurrence is common, and mortality is high. There is limited data on optimal management strategies or recurrence of non-structural heart disease-related PB in children.
