Usefulness of cerebral NIRS in detecting the effects of pediatric sleep apnea.
Children with sleep apnea have increased morbidity if the sleep apnea is untreated. Polysomnography (PSG) is used to detect sleep apnea, but in children, there are technical difficulties that make the diagnosis more difficult. Cerebral near infrared spectroscopy (NIRS) has the ability to detect tissue hypoxia by measuring regional oxygen saturation (rSO2 ). We hypothesized that when used as an adjunct to PSG testing, cerebral NIRS would better detect the effects of sleep apnea in children than arterial pulse oximetry (SpO2 ). Specifically, we aimed to show that the apnea/hypopnea index (AHI) calculated with rSO2 from the NIRS would be greater than that calculated with SpO2 . ⋯ Consistent with the ability of NIRS to detect tissue hypoxia, we found that the AHI calculated with rSO2 was greater than that using SpO2 . We conclude that NIRS has potential as a valuable adjunct to PSG in evaluating patients for sleep apnea and warrants further investigation for this purpose.

Comparative StudyComparison of two aspiration techniques of bronchoalveolar lavage in children.
Although bronchoalveolar lavage (BAL) via flexible bronchoscopy is an essential diagnostic tool, its technique is not standardized in children. Our objective was to compare two different aspiration techniques of BAL in children (continuous wall suction vs. handheld syringe suction) in regards to the percentage of fluid recovered and the odds of performing a technically acceptable procedure (i.e., >40% of volume return). ⋯ Our results suggest that handheld syringe suction offers a higher percentage of volume return from BAL and increases the odds of performing a technically acceptable procedure in children when compared to continuous wall suction.

Obesity negatively impacts lung function in children and adolescents.
To investigate the relationship between weight status (body mass index [BMI] percentile and BMI z-score) and lung volumes in healthy children and adolescents. ⋯ Our results show that increasing weight status in children and adolescents is associated with a general reduction in lung volume measurements, which may reflect impaired lung function, increased respiratory symptoms, and decreased functional status.

Randomized Controlled TrialSeven percent hypertonic saline--0.1% hyaluronic acid in infants with mild-to-moderate bronchiolitis.
Our study was aimed to evaluate the efficacy of 7% hypertonic saline and 0.1% hyaluronic acid (7% HS-HA) given by inhalation, in infants hospitalized for mild-to-moderate bronchiolitis. ⋯ 7% HS-HA is a safe and effective therapy in treating infants hospitalized for mild-to-moderate bronchiolitis.
