An 85-year-old, never-smoking man presented with exertional dyspnea. He had been exposed to silica dust in the work place. Chest computed tomography revealed bronchial wall thickening without emphysema. A pulmonary function test showed airflow obstruction without impaired gas transfer. Airway hyperresponsiveness and reversibility were not evident. A transbronchial lung biopsy showed findings suggestive of mineral dust exposure, such as fibrosis and slight pigmentation of bronchioles. He was diagnosed with non-smoking chronic obstructive pulmonary disease (COPD) due to occupational exposure to silica dust...

Bronchiolitis is a common condition in children less than 2 years of age and is a leading cause of infant hospitalization. Acute bronchiolitis is characterized by acute wheezing in infants or children and is associated with signs or symptoms of respiratory infection; the most common etiologic agent is respiratory syncytial virus. There is a lack of consensus regarding the clinical definition of acute viral bronchiolitis in children and hence the management varies across the globe. Usually it does not require investigation, treatment is merely supportive and a conservative approach seems adequate in the majority of children, especially for the youngest ones...

BACKGROUND AND OBJECTIVES: Adoption of clinical respiratory scoring as a quality improvement (QI) tool in bronchiolitis has been temporally associated with decreased bronchodilator usage. We sought to determine whether documented use of a clinical respiratory score at the patient level was associated with a decrease in either the physician prescription of any dose of bronchodilator or the number of doses, if prescribed, in a multisite QI collaborative. METHODS: We performed a secondary analysis of data from a QI collaborative involving 22 hospitals...

Bronchiolitis is the leading cause of infant hospitalizations in the United States. Despite clinical practice guidelines discouraging the utilization of non-evidence-based therapies, there continues to be wide variation in care and resource utilization. A pre-post physician focused educational intervention was conducted with the aims to reduce the use of non-evidence-based medical therapies, including bronchodilators, among patients admitted for bronchiolitis. Among patients meeting inclusion criteria (pre: n = 45; post: n = 47), bronchodilator use decreased by 50% ( P < ...

Hydrogen sulfide (H2S) is a gasotransmitter employed for intra- and inter-cellular communication in almost all organ systems. This study investigates the role of endogenous H2S in nerve-evoked relaxation of pig terminal bronchioles with 260 μm medium internal lumen diameter. High expression of the H2S synthesis enzyme cystathionine γ-lyase (CSE) in the bronchiolar muscle layer and strong CSE-immunoreactivity within nerve fibers distributed along smooth muscle bundles were observed. Further, endogenous H2S generated in bronchiolar membranes was reduced by CSE inhibition...

Viral bronchiolitis is a common clinical syndrome affecting infants and young children. Concern about its associated morbidity and cost has led to a large body of research that has been summarised in systematic reviews and integrated into clinical practice guidelines in several countries. The evidence and guideline recommendations consistently support a clinical diagnosis with the limited role for diagnostic testing for children presenting with the typical clinical syndrome of viral upper respiratory infection progressing to the lower respiratory tract...

AIM: The united airway disease (UAD) hypothesis suggests that allergic rhinitis and asthma develop together. We evaluated the evidence for and against the UAD hypothesis at five to seven years of age after hospitalisation for bronchiolitis at less than six months. METHODS: This study used prospective follow-up data for 102 children hospitalised for bronchiolitis under the age of six months. We included the presence of previous and current asthma, prolonged rhinitis and skin prick tests (SPT) to common inhaled allergens and lung function by impulse oscillometry (IOS) at five to seven years of age...

OBJECTIVE: Unnecessary care is well established as a quality problem affecting acute viral bronchiolitis, one of the most common pediatric illnesses. Although there is an extensive quality improvement literature on the disease, published work primarily reflects the experience of freestanding children's hospitals. We sought to better understand the specific barriers and drivers for successful quality improvement in community and nonfreestanding children's facilities. METHODS: We undertook a mixed methods study to identify correlates of success in a bronchiolitis quality improvement collaborative of community hospitals and children's hospitals within adult hospitals...

Post-infectious bronchiolitis obliterans (PIBO) is a small airways disease characterized by fixed airflow limitation. Therefore, inhaled bronchodilators and corticosteroids are not recommended as maintenance therapy options. The management of PIBO currently consists only of close monitoring of affected patients, aimed at the prevention and early treatment of pulmonary infections. In recent years, there has been an increase in the incidence of PIBO in the pediatric population. Patients with PIBO are characterized by a progressive decline in lung function, accompanied by a decrease in overall functional capacity...

OBJECTIVE: Post-infectious bronchiolitis obliterans (PIBO) is a clinical entity that has been classified as constrictive, fixed obstruction of the lumen by fibrotic tissue. However, recent studies using impulse oscillometry have reported bronchodilator responses in PIBO patients. The objective of this study was to evaluate bronchodilator responses in pediatric PIBO patients, comparing different criteria to define the response. METHODS: We evaluated pediatric patients diagnosed with PIBO and treated at one of two pediatric pulmonology outpatient clinics in the city of Porto Alegre, Brazil...

Management of acute viral bronchiolitis is largely supportive. There is currently no proven effective therapy other than oxygen for hypoxic children. The evidence indicates that there is no routine benefit from inhaled, rapid short-acting bronchodilators, adrenaline or ipratropium bromide for children with acute viral bronchiolitis. Likewise, there is no demonstrated benefit from routine use of inhaled or oral corticosteroids, inhaled hypertonic saline nebulisation, montelukast or antibiotics. The last should be reserved for children with severe disease, when bacterial co-infection is suspected...
