Elevation of the intracellular free Ca(2+) concentration regulates many functional responses in airway smooth muscle, including contraction, proliferation, adhesion, and cell survival. This increase in calcium can be achieved by a release from internal stores (sarcoplasmic reticulum) and/or entry across the cell membrane from the extracellular environment. The molecular identity of this calcium...

BACKGROUND Bullying among children and adolescents is a public health concern; victimization is associated with psychological and physical health problems. The purpose of this study is to examine temporal trends in bullying victimization among school-aged children in Europe and North America. METHODS Data were obtained from cross-sectional self-report surveys collected as part of the Health B...

Rhinovirus (RV) infections can alter lower airway physiology and inflammation, yet the characteristics of RV replication in lower airway cells are incompletely understood. An RV serotype 16 (RV16)-specific monoclonal antibody was identified. Immunohistochemistry and an infectious center assay were used to quantitate the infectivity of RV16 in primary bronchial and adenoidal epithelial cells. Th...

INTRODUCTION According to guidelines, the diagnosis of COPD should be confirmed by post-bronchodilator (post-BD) airway obstruction on spirometry; however, in clinical practice, this is not always performed. The aim of this population-based study was to compare clinical characteristics and prognosis, assessed as mortality, between subjects with airway obstruction divided into pre- but not post-...

Airway management in critically ill patients involves the identification and management of the potentially difficult airway in order to avoid untoward complications. This focus on difficult airway management has traditionally referred to identifying anatomic characteristics of the patient that make either visualizing the glottic opening or placement of the tracheal tube through the vocal cords ...

Airway management in critically ill patients involves the identi cation and management of the potentially dif cult airway in order to avoid untoward complications. This focus on dif cult airway management has traditionally referred to identifying anatomic characteristics of the patient that make either visualizing the glottic opening or placement of the tracheal tube through the vocal cords dif...

Whether exhaled NO helps to identify a specific phenotype of asthmatic patients remains debated. Our aims were to evaluate whether exhaled NO (FENO(0.05)) is independently associated (1) with underlying pathophysiological characteristics of asthma such as airway tone (bronchodilator response) and airway inflammation (inhaled corticosteroid [ICS]-dependant inflammation), and (2) with clinical ph...

Nontoxic adenomatous multinodular goiter (AMNG) in infants is a rare condition. We discuss an extremely rare case of a nontoxic AMNG in a 3-month-old female presenting with airway obstruction. Surgical resection of the mass was performed to reduce the burden on the airway and for diagnosis. The literature is reviewed, and the clinical characteristics, pathology, and surgical treatment are discu...

OBJECTIVES/HYPOTHESIS To describe the clinical presentation and airway characteristics of infants with airway hemangiomas and concomitant PHACE syndrome and to determine the prevalence of airway hemangiomas in PHACE subjects at our institution. STUDY DESIGN Case series. METHODS Retrospective review including clinical presentation, airway findings, treatment measures, and outcomes. RESULTS...

laryngotracheal and tracheobronchial injuries are uncommon, and their successful diagnosis and management often require a high level of expertise. this paper aimed at retrospective analysis of a thoracic surgeon's experience in the diagnosis and management of traumatic injuries to the larynx, trachea and major bronchi. forty one patients with major airway trauma were managed from march 1994 to ...
