Continuous positive airway pressure (CPAP) has been used in infants with bronchiolitis for decades. Recently, high flow nasal cannula (HFNC) therapy was introduced We conducted a retrospective study of treatment with CPAP vs. HFNC between 2013 and 2015, comparing the development in respiratory rate, fraction of inspired oxygen (FiO2) and heart rate, treatment failure, duration of treatment, and length of hospital stay. A sample size of 49 children were included. Median age was 1.9 months. Median baseline pCO₂ was 7...

The use of gold nanoparticles as drug delivery system represents a promising issue for diseases without effective pharmacological treatment due to insufficient local drug accumulation and excessive systemic toxicity. Bronchiolitis obliterans syndrome (BOS) represents about 70% of cases of chronic lung allograft dysfunction, the main challenge to long term lung transplantation. It is believed that due to repeated insults to epithelial bronchiolar cells local inflammatory response creates a milieu that favours epithelial mesenchymal transition and activation of local mesenchymal cells leading to airway fibro-obliteration...

As a modern phenomenon, there is currently limited understanding of the possible toxic effects and broader implications of electronic nicotine delivery systems (ENDS). Large volumes of aerosolized particles are inhaled during "vaping" and there are now an increasing number of case reports demonstrating toxic effects of ENDS, as well as human studies demonstrating impaired lung function in users. This article presents a case of respiratory bronchiolitis interstitial lung disease (RB-ILD) precipitated by vaping in a 33-year-old male with 10 pack years of traditional cigarette and prior treatment for mixed germ cell tumour...

Bronchiolitis obliterans with organizing pneumonia is an inflammatory reaction that can occur as a consequence of various pulmonary affections. Radiotherapy is not the sole and systematic cause of bronchiolitis obliterans with organizing pneumonia. Radiation-induced should not be confused with post-radiation, dose-dependent, inflammatory pulmonary fibrosis, which is non-immunological and located within the irradiation field. The role of immunity, local inflammation and individual radiosensitivity in bronchiolitis obliterans with organizing pneumonia is not well defined...

In this analysis of a prospective, multicenter study of children hospitalized with bronchiolitis, 925 had RSV-A and 649 had RSV-B. Overall, bronchiolitis severity did not differ by RSV subtype. However, among children with RSV-only bronchiolitis, those children with RSV-A had higher risk of intensive care treatment (OR, 1.31; 95%CI, 1.00-1.71; P=0.048) when compared with those having RSV-B.

While a high quality discharge from a Pediatric Emergency Department helps caregivers feel informed and prepared to care for their sick child at home, poor adherence to discharge instructions leads to unnecessary return visits, negative health outcomes, and decreased patient satisfaction. Nurses at the Inova Loudoun Pediatric ED utilized the Johns Hopkins Model of Evidence Based Practice to answer the following question: Among caregivers who have children discharged from the ED, does the addition of video discharge instructions (VDI) to standard written/verbal discharge instructions (SDI) result in improved knowledge about the child's diagnosis, treatment, illness duration, and when to seek further medical care? METHODS: A multidisciplinary team reviewed available evidence and created VDI for three common pediatric diagnoses: gastroenteritis, bronchiolitis, and fever...

Respiratory diseases account for about 25% of all pediatric consultations, and 10% of these are for asthma. The other main pediatric respiratory diseases, in terms of incidence, are bronchiolitis, acute bronchitis and respiratory infections. Oral corticosteroids, in particular prednisolone, are often used to treat acute respiratory diseases given their anti-inflammatory effects. However, the efficacy of treatment with oral corticosteroids differs among the various types of pediatric respiratory diseases. Notably, also the adverse effects of corticosteroid treatment can differ depending on dosage, duration of treatment and type of corticosteroid administered - a case in point being growth retardation in long-course treatment...

Graft failure represents a leading cause of mortality following organ transplantation. Acute late-onset graft failure has not been widely reported. This paper describes the demographics, CT imaging pathology findings and treatment of patients presenting with the latter. A retrospective review of lung transplant recipients at 2 large-volume centres was performed. Acute late-onset graft failure was defined as sudden onset of bilateral infiltrates with an oxygenation index <200 without identifiable cause or concurrent extra-pulmonary organ failure...

The human respiratory syncytial virus (hRSV) is the causative agent for high rates of hospitalizations due to viral bronchiolitis and pneumonia worldwide. Such a disease is characterized by an infection of epithelial cells of the distal airways that leads to inflammation and subsequently to respiratory failure. Upon infection, different pattern recognition receptors recognize the virus and trigger the innate immune response against the hRSV. Further, T cell immunity plays an important role for virus clearance...

Cystic lung disease (CLD) is a group of lung disorders characterized by the presence of multiple cysts, defined as air-filled lucencies or low-attenuating areas, bordered by a thin wall (usually < 2 mm). The recognition of CLDs has increased with the widespread use of computed tomography. This article addresses the mechanisms of cyst formation and the diagnostic approaches to CLDs. A number of assessment methods that can be used to confirm CLDs are discussed, including high-resolution computed tomography, pathologic approaches, and genetic/ serologic markers, together with treatment modalities, including new therapeutic drugs currently being evaluated...

Severe viral lower respiratory infections are a major cause of infant morbidity. In developing countries, respiratory syncytial virus (RSV)-bronchiolitis induces significant mortality, whereas in developed nations the disease represents a major risk factor for subsequent asthma. Susceptibility to severe RSV-bronchiolitis is governed by gene-environmental interactions that affect the host response to RSV infection. Emerging evidence suggests that the excessive inflammatory response and ensuing immunopathology, typically as a consequence of insufficient immunoregulation, leads to long-term changes in immune cells and structural cells that render the host susceptible to subsequent environmental incursions...

Allogeneic hematopoietic stem cell transplantation is hampered by chronic graft-versus-host disease (cGVHD) resulting in multi-organ fibrosis and diminished function. Fibrosis in lung and skin leads to progressive bronchiolitis obliterans (BO) and scleroderma, respectively, for which new treatments are needed. We evaluated pirfenidone, a FDA approved drug for idiopathic pulmonary fibrosis, for its therapeutic effect in cGVHD mouse models with distinct pathophysiology. In a full MHC-mismatched, multi-organ system model with BO, donor T cell responses that support pathogenic antibody production are required for cGVHD development...

PURPOSE OF REVIEW: This review summarizes the current knowledge regarding the role of Enterovirus D68 (EV-D68) in community-acquired pneumonia (CAP) in children. RECENT FINDINGS: EV-D68 is an emergent viral pathogen. Since its first isolation in 1962 in California in four children suffering from CAP and bronchiolitis, EV-D68 has been rarely detected from respiratory specimens. However, recently, EV-D68 infection has raised concerns in the international community because of outbreaks in 2014 in the USA and the increased number of children with EV-D68-associated severe respiratory illnesses, including pneumonia, that have been reported in many other countries around the world...

BACKGROUND: Bronchiolitis is a common cause of hospitalization among infants. The limited effectiveness of conventional medication has prompted the use of complementary and alternative medicine (CAM) as alternative or adjunctive therapy for the management of bronchiolitis. AIMS: To determine the effectiveness and safety of CAM for the treatment of bronchiolitis in infants aged less than 2 years. METHODS: A systematic electronic search was performed in Medline, Embase, CINAHL, AMED, and Cochrane Central Register of Controlled Trials (CENTRAL) from their respective inception to June 30, 2016 for studies evaluating CAM as an intervention to treat bronchiolitis in infants (1 month to 2 years of age)...

Chronic lung transplant rejection (termed chronic lung allograft dysfunction [CLAD]) is the main impediment to long-term survival after lung transplantation. Bone marrow-derived mesenchymal stromal cells (MSCs) represent an attractive cell therapy in inflammatory diseases, including organ rejection, given their relative immune privilege and immunosuppressive and tolerogenic properties. Preclinical studies in models of obliterative bronchiolitis and human trials in graft versus host disease and renal transplantation suggest potential efficacy in CLAD...
