2. 1. Exercise induced breathing problems in adolescents

   Author : Henrik Johansson; Margareta Emtner; Christer Janson; Kai-Håkon Carlsen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; dyspnoea; bronchoconstriction; laryngeal obstruction; adolescents; HRQoL; physical activity; Lungmedicin; Lung Medicine;

   Abstract : Experiencing respiratory symptoms in conjunction with exercise is common in children and adolescents and can have a negative impact on daily life. The aim of the thesis was to estimate the prevalence of exercise-induced dyspnoea, exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (E-ILO) in a general adolescent population, and to explore factors associated with EIB.

4. 2. Ventilation/Perfusion Matching and its Effect on Volatile Pharmacokinetics

   Author : Moritz Andreas Kretzschmar; Anders Larsson; Jan Jakobsson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; Animal models in research; Mass spectrometry; Gas chromatography; MIGET; Ventilation-perfusion; Desflurane; Isoflurane; Bronchoconstriction; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Abstract : The mismatching of alveolar ventilation and perfusion (VA/Q) is the major determinant of impaired gas exchange. The gold standard for analyzing VA/Q distribution is the multiple inert gas elimination technique (MIGET), conventionally based on gas chromatography (GC), and, although simple in principle, a technically demanding procedure limiting its use.

5. 3. Exercise-induced laryngeal obstruction : Prevalence, laryngeal findings and evaluation of treatment

   Author : Katarina Norlander; Leif Nordang; Malin Svensson; Riitta Möller; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; laryngeal obstruction; bronchoconstriction; CLE-score; EILOMEA;

   Abstract : Exercise-induced laryngeal obstruction (EILO) is one of many different causes for adolescents to experience dyspnoea during exercise. Objective exercise-testing with continuous video laryngoscopy is crucial for a correct diagnosis since it is difficult to differentiate EILO from other exercise related conditions in the airways only on the symptomatology.

6. 4. Studies of exercise-induced bronchoconstriction to define protective mechanisms in asthma

   Author : Johan Bood; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Exercise-induced bronchoconstriction (EIB) occurs in the majority of asthmatics following vigorous exercise. EIB is caused by a loss of water from the airways creating a hyperosmolar environment in the tissue that in turn triggers the release of bronchoconstrictive mediators. READ MORE

7. 5. An experimental study of mediators in allergic bronchoconstriction with focus on eicosanoids

   Author : Ewa Selg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Leukotrienes; prostaglandins; histamine; guinea pig lung; ovalbumin; mast cell; cyclooxygenase; airway smooth muscle; COX inhibitors; NSAIDs;

   Abstract : Mast cells have a central role in the inflammatory response in airways of both atopic and non-atopic asthmatics. The mast cell-derived mediators such as histamine, leukotriene C4 and prostaglandin D2, released upon activation of the cell, produce acute bronchoconstriction that is characteristic of the early asthmatic response (EAR), and contribute to the development of airway inflammation and hyperresponsiveness following the initial reaction.
