  1. 1. Exploring small airways using breath analyses

    Författare :Emilia Viklund; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exhaled particles; small airways; alveolar nitric oxide; SARS-CoV-2; birch pollen; smoking; lining fluid;

    Sammanfattning : Background: Airway irritants such as allergens, tobacco smoke and viruses may cause damage in the small airways, usually undetected with routine diagnostic methods. Analyses of endogenously produced nitric oxide (NO) and endogenously produced small droplets (i.e. LÄS MER

  3. 2. Towards Improved Diagnostics and Monitoring in Childhood Asthma : Methodological and Clinical Aspects of Exhaled NO and Forced Oscillation Technique

    Författare :Charlotte Heijkenskjöld Rentzhog; Malinovschi Andrei; Lennart Nordvall; Kjell Alving; Lauri Lehtimäki; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; children; exhaled NO; forced oscillation technique; airway inflammation; small airways; asthma diagnostics; Pediatrik; Pediatrics; Lungmedicin; Lung Medicine;

    Sammanfattning : Background: Asthma is a heterogeneous disease. Diagnosis relies on symptom evaluation and lung function tests using spirometry. Symptoms can be vague. Spirometry is effort-dependent and does not reliably evaluate small airways. LÄS MER

  4. 3. The asthmatic airway response – effects on physiology and biomarkers

    Författare :Henning Stenberg; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :Asthma; Exhaled breath temperature; Exercise; Allergen challenge; Small airways; Airway provocations; Spirometry; Impulse oscillometry; Inert gas washout; Body plethysmography; Club cell protein CC16 ;

    Sammanfattning : Asthma is a common airway inflammatory disease, associated with a variable degree of airway obstruction. It is a heterogeneous condition with large variations in severity and clinical presentation. Moreover, disease activity can vary from time to time. Taken together, these factors make the diagnosis, monitoring and treatment of asthma challenging. LÄS MER

  5. 4. Nasal polyps. A clinical study of endoscopic score systems and epidemiology

    Författare :Leif Johansson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nasal polyps; score system; endoscope; epidemiology; airways; HRQL;

    Sammanfattning : Introduction: Nasal polyps are a common disease, the etiology and pathogenesis of which are still unclear. For diagnosis, a nasal endoscope is essential, while for follow-up treatment, a reliable score system is necessary. The existing score systems consist of few score steps and measure only large changes in polyp size. LÄS MER

  7. 5. Vasodilator actions of EDHF and anandamide

    Författare :David Andersson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vanilloid receptors; afferent neurons; anandamide; cannabinoids; potassium channels; hyperpolarization; vasodilation; Vascular endothelium; arteries; airways; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Sammanfattning : Vasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. LÄS MER
