Asymptomatic Esophageal Eosinophilia in an 11-Year-Old with Severe Persistent Asthma.

Asymptomatic esophageal eosinophilia (aEE) is a rare presentation, where patients have increased eosinophils in esophageal mucosa but lack any esophagus-related symptoms. Cases of aEE have only been documented in adults, and little is known about its clinical significance and whether treatment is warranted. We report a case of an 11-year-old patient with uncontrolled severe persistent asthma who underwent flexible bronchoscopy and upper endoscopy as a part of complete aerodigestive evaluation.

Seizure-Induced Hemoptysis in a Pediatric Patient.

Hemoptysis can complicate seizures, albeit rarely. This unfamiliar presentation, reported infrequently in adults, can also affect children. This remains a rare clinical entity in pediatrics and we report one such case and its association with sterol carrier protein (SCP) gene mutation.

Spirometric Changes After Initiation of Hydroxyurea in Children With Sickle Cell Anemia.

Individuals with sickle cell disease (SCD) develop a decline in lung function over time. Hydroxyurea (HU) is the most common disease-modifying therapy used in SCD. We hypothesized that children with SCD treated with HU will have a slower decline in pulmonary function.

Peak Cough Flow in Children with Neuromuscular Disorders.

Purpose: Patients with neuromuscular disease (NMD) experience weakened cough due to progressive respiratory muscle weakness. Peak cough flow (PCF) measurements derived from adult populations are used to recommend initiation of assisted cough therapies. The objective of this study was to characterize PCF values among pediatric patients with NMD.

Clinical definition of respiratory viral infections in young children and potential bronchiolitis misclassification.

Viral respiratory infections are often grouped as a single respiratory syndrome named 'viral bronchiolitis', independently of the viral etiology or individual risk factors. Clinical trials and guidelines have used a more stringent definition of viral bronchiolitis, including only the first episode of wheezing in children less than 12 months of age without concomitant respiratory comorbidities. There is increasing evidence suggesting that this definition is not being followed by pediatric care providers, but it is unclear to what extent viral respiratory infections are currently misclassified as viral bronchiolitis using standard definitions.
