Parental Perception and Barriers Regarding COVID-19 Vaccination in Technology Dependent Children.

Introduction: Children who use chronic home mechanical ventilation are at high risk for respiratory infections and mortality. They are also at increased risk for developing severe COVID-19 infection. The primary goal of this study was to evaluate the parental perception of the COVID-19 vaccine in pediatric patients with technology dependence.

Diagnosis of EVALI in Adolescents During the COVID-19 Pandemic: A Case Series.

Objective: Electronic-cigarette or vaping use-associated lung injury (EVALI) is an illness that requires further awareness for appropriate diagnosis and management. This series is a retrospective chart review of EVALI cases admitted from June to December 2020 at a large academic children's hospital in New York.

Methods: Notably during this time, the coronavirus disease 2019 (COVID-19) global pandemic rendered the world under strict quarantine mandates.

Asthma and COVID-19: An early inpatient and outpatient experience at a US children's hospital.

Background: Initially, persistent asthma was deemed a risk factor for severe COVID-19 disease. However, data suggests that asthmatics do not have an increased risk of COVID-19 infection or disease. There is a paucity of data describing pediatric asthmatics with COVID-19.

American Thoracic Society 2019 Pediatric Core Curriculum.

The American Thoracic Society Pediatric Core Curriculum updates clinicians annually in pediatric pulmonary disease in a 3 to 4 year recurring cycle of topics. The 2019 course was presented in May during the Annual International Conference. An American Board of Pediatrics Maintenance of Certification module and a continuing medical education exercise covering the contents of the Core Curriculum can be accessed online at www.

On the nature of pleural involvement in necrotizing pneumonia: a report of two cases of life threatening late complications.

Suppurative complications of pneumonia such as empyema, lung abscess, pyopneumothorax, and necrotizing pneumonia (NP) are uncommon in children. Over the last decade an increasing incidence of NP has been reported. Streptococcus pneumoniae continues to be the predominant causative organism of NP, and while sporadic cases were reported prior to routine administration of heptavalent pneumococcal vaccine, a marked increase in NP appears to relate to replacement pneumococcal strains.

Probiotic administration in early life, atopy, and asthma: a meta-analysis of clinical trials.

Background And Objective: Probiotics may reduce the risk of atopy and asthma in children. However, results from clinical trials have been conflicting, and several of them may have been underpowered. We performed a meta-analysis of randomized, placebo-controlled trials to assess the effects of probiotic supplementation on atopic sensitization and asthma/wheeze prevention in children.

Obliterative lower airway lesions in childhood: bronchoscopic diagnosis and clinical spectrum.

Previous reports have described structural airway abnormalities in children with non-cystic fibrosis chronic supportive lung disease as well as obliterative membranes in the major bronchi of cystic fibrosis patients. The putative paradigm proposed in the evolution of these membranes invokes intense inflammation resulting in granulation tissue and neovascularization with the formation of pyogenic granuloma and eventually fibrosis. Our series of four cases widens the spectrum of conditions that may be conducive to large airway obliteration to include non-suppurative chronic infections and possibly immunosuppression.

Treatment of disorders characterized by reversible airway obstruction in childhood: are anti-cholinergic agents the answer?

Release of acetylcholine from parasympathetic nerves in the airways activates postjunctional muscarinic receptors present on smooth muscle, submucosal glands and blood vessels. This triggers bronchoconstriction, muscle hypertrophy, mucus secretion, and vasodilatation, respectively. The release of acetylcholine from parasympathetic nerves in lungs is induced by a variety of stimuli and downregulated by the inhibitory activity of neuronal M2 muscarinic receptors via a feedback mechanism.

Special considerations in pediatric asthma.

Asthma is the most common chronic illness in childhood with challenges that revolve around interventions that can potentially alter the course of the disease and concerns regarding the safety of regular use of controller medications. Recent studies suggest that the use of inhaled corticosteroids in very young children with frequent wheezing episodes and at high risk for asthma, while effective, does not alter the eventual progression to asthma. As a controller medication, the safety of inhaled corticosteroids as regards efficacy and risk are reviewed.
