Prophylactic inhaled corticosteroids for the management of recurrent croup.

OBJECTIVES: Croup is characterized by a barky cough, inspiratory stridor, hoarseness and varying degrees of respiratory distress. Acute croup episodes are often treated with oral, inhaled, or intravenous corticosteroids. Recurrent croup, defined as more than 2-3 episodes of acute croup in the same patient, can mimic asthma. We hypothesized that inhaled corticosteroids (ICS) given at the first sign of a respiratory viral prodrome can be a safe treatment to reduce the frequency of recurrent croup episodes in children without fixed airway lesions. METHODS: A retrospective chart review of patients being treated over an 18-month period was performed at a large tertiary care pediatric hospital following Institutional Review Board (IRB) approval. Patients under 21 years old referred to Pediatric Pulmonology, Otolaryngology, or Gastroenterology for recurrent croup were analyzed for their demographics, medical history, evaluation, treatment and clinical improvement. A Fisher's two-tailed exact test was used to compare the number of croup episodes before and after interventions. RESULTS: 124 patients were included in our analysis: 87 male and 34 female with a mean age of 54 months. Of these, 78 had >5 episodes of croup, 45 had 3-5, and 3 had 2 episodes prior to their first visit for recurrent croup. Operative direct laryngoscopy/bronchoscopy was performed in 35 patients (27.8%), with 60% showing a normal exam without fixed lesions. Ninety-two patients (74.2%) were treated with ICS, 24 were lost to follow up. Of the remaining 68 treated patients, 59 (86.7%) saw improvement with reduced severity and overall number of episodes of croup. Additionally, patients with >5 episodes of croup (47) as compared to <5 (12) were more likely to improve with ICS, (p = 0.003). There were no adverse reactions reported with ICS treatment. CONCLUSION: The novel initiation of ICS at the earliest sign of a viral upper respiratory infection shows promise as a safe preventative treatment to mitigate the frequency of recurrent croup episodes.

Asthma in Children: A Brief Review for Primary Care Providers.

Pediatric asthma is a common chronic condition with wide-ranging implications for children's health, their families, and the health care system. The diagnosis may be relatively straightforward for the child with characteristic symptoms, triggers, and response to therapy, but there are other less common presentations that can make the diagnosis challenging. Diagnosing asthma in a toddler with recurrent wheezing can be particularly difficult. Treating asthma in a step-wise fashion usually reduces symptom frequency and improves asthma control. Asthma exacerbations and poor outcomes from acute exacerbations remain an area in which we have room for improvement. This article provides an overview of the diagnosis and management of childhood asthma for the primary care provider. [Pediatr Ann. 2019;48(3):e103-e109.].

Marijuana medusa: The many pulmonary faces of marijuana inhalation in adolescent males.

Marijuana use has risen dramatically over the past decade. Over this same time period, pediatric hospitals have seen an increase in presentation of adolescents with acute respiratory symptoms after recent marijuana inhalation. We report a case series of three adolescent males with significant findings of bilateral pulmonary nodules and ground glass opacities on chest imaging associated with recent marijuana inhalation. Lung biopsies in two of the three patients confirmed silica-induced pneumoconiosis. The third patient was diagnosed with acute hypersensitivity pneumonitis without lung biopsy. Improvement in clinical symptoms and lung function testing were noted in two of three patients after marijuana inhalation cessation. This case series highlights the variety of severe pulmonary presentations in adolescents following recent marijuana inhalation. Future studies are required to assess whether these presenting pulmonary complications are from direct marijuana exposure or indirect associations with marijuana inhalation injuries.

The use of light's criteria in hospitalized children with a pleural effusion of unknown etiology.

OBJECTIVE: Pleural effusions are common in pediatrics. When the etiology of a pleural effusion remains unknown, adult literature recommends the use of Light's criteria to differentiate a transudate from an exudate. Pediatricians may rely on adult literature for the diagnostic management of pleural effusions as Light's criteria has not been validated in children. The purpose of this study was to review the use of Light's criteria in hospitalized children with a pleural effusion of unknown etiology. METHODS: Retrospective review was performed on children hospitalized with a pleural effusion requiring chest tube placement or thoracentesis between January 1, 2016 to January 1, 2017 at Children's Hospital Colorado. Charts were reviewed for primary team, use of Light's criteria, pleural effusion diagnosis, and 30-day recurrence of repeat intervention or fluid analysis. RESULTS: Sixty-eight patients were hospitalized with a pleural effusion of unknown etiology requiring intervention. Only 16 pleural effusions (24%) were classified using Light's criteria. In those patients for whom Light's criteria was used, a diagnosis or change in management occurred in 10 of 16 patients (63%). Pleural effusions were most common on the cardiology service (26/68). Use of Light's criteria was most frequent on the oncology service (7/8). Thirty-day need for repeat intervention was lower in those with Light's criteria (13%) compared to those without (27%). CONCLUSIONS: Light's criteria were utilized infrequently in hospitalized children with a pleural effusion of unknown etiology at a single institution. There was considerable practice variation among provider teams. When utilized, Light's criteria assisted in making a diagnosis or changing management in many patients, and may lead to a reduction in 30-day recurrence requiring repeat intervention.

Uremic pleuritis: A case report and review of recurrent exudative pleural effusions in children.

Despite similar mechanisms driving pleural fluid accumulation, the causes of pleural effusions in children differ significantly from that of adults. When a pleural effusion re-occurs in an adult, literature recommends early thoracentesis, and consideration for pleuroscopy with biopsy to guide the diagnostic evaluation. In children, there is a paucity of literature for guiding management of recurrent exudative pleural effusion. We present an unusual pediatric case of uremic pleuritis with recurrent pericardial and exudative pleural effusions.

Measuring Pediatric Bronchoscopy Outcomes Using an Electronic Medical Record.

RATIONALE: Bronchoscopy procedures should be tracked for safety, quality improvement, and federal regulations. OBJECTIVE: The aim of this study was to develop and test a method for evaluating flexible bronchoscopy use and outcomes using the electronic medical record (EMR) system in current clinical use at a large children's hospital. METHODS: We created a custom bronchoscopy procedure note for our EMR system (Epic Systems Corporation) to track demographics, bronchoscopist, coordinated procedures, and outcome. Unplanned outcomes in children were defined as a disposition (admission to the hospital or elevation of care) after flexible bronchoscopy that differed from the preoperative plan. Readmissions to the hospital and emergency visits within our hospital system were also tracked electronically. Unplanned outcomes and readmissions were evaluated by a bronchoscopy quality team. MEASUREMENTS AND MAIN RESULTS: Over 2.5 years, we tracked 1,297 bronchoscopic procedures performed on 1,161 patients (60% male, 78% American Society of Anesthesiologists class 2 or 3, mean age 5.5 yr [range, 0.02-40 yr]). Overall, 27 unplanned outcomes occurred (2.1%). The risk of unplanned outcomes did not appear to be different between procedures performed by a trainee with faculty oversight and those performed by a faculty member alone. Patients with multiple same-day procedures were more likely to have unplanned outcomes (21 of 27 [78%], P = 0.004) than were patients who had flexible bronchoscopy alone. The relative risk (RR) of having an unplanned outcome was not different from flexible bronchoscopy alone in the subset of patients with multiple procedures coordinated through our multidisciplinary aerodigestive clinic (RR 0.7; 95% CI, 0.1-3.4). The risk of unplanned events was significantly elevated in children with coordinated procedures scheduled outside the aerodigestive group (RR, 5.8; 95% CI, 2.4-14.5). Ten patients (<1%) were readmitted or seen urgently within 1 week; three of these unplanned outcomes were attributed to complications of the bronchoscopy. CONCLUSIONS: An EMR system may be used to track procedural outcomes. Unplanned outcomes after flexible bronchoscopy were infrequent at our institution. Children who underwent multiple procedures had unplanned outcomes more often; however, the subset of children who underwent coordinated procedures through our multidisciplinary aerodigestive clinic did not demonstrate this increased risk.

Primary Ciliary Dyskinesia in Children: A Review for Pediatricians, Allergists, and Pediatric Pulmonologists.

Primary ciliary dyskinesia (PCD) is a rare genetic condition that causes impaired mucociliary clearance due to poorly functioning cilia. PCD is one disease manifestation of the many recently recognized associations with ciliary malfunction, referred to as "ciliopathies." Manifestations of PCD commonly begin in the neonatal period with cough, pneumonia, and chronic ear infections or effusions. Approximately half of the affected individuals have situs inversus totalis. The diagnosis is often made in later childhood or early adulthood, because symptoms mimic more common childhood illnesses and because the definitive diagnosis of PCD can be challenging. Treatment recommendations are largely based on therapies used for other conditions with impaired mucociliary clearance in the absence of evidence-based research specific for PCD. Early recognition and initiation of both otolaryngologic and pulmonary management might reduce potential long-term morbidities. The purpose of this article is to update primary care providers, allergists, and pediatric pulmonologists on recent advances in this interesting condition.
