1. Subglottic stenosis : Diagnostics, endoscopic treatment and follow-up
Sammanfattning : Subglottic stenosis (SGS) is a rare condition of upper airway obstruction transforming tracheal mucosa below the vocal folds into scar tissue. It is primarily caused by laryngotracheal trauma and infrequent autoimmune conditions ofsystemic inflammation. LÄS MER
2. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia
Sammanfattning : In idiopathic achalasia, degeneration of the inhibitory innervation of the esophageal smooth muscle results in absence of primary peristalsis and in incomplete relaxation of the lower esophageal sphincter (LES). All treatments for achalasia aim at reducing the pressure gradient across the LES, thus facilitating esophageal emptying by gravity. LÄS MER
3. Aspects on the Diagnosis and Treatment of Patients with Achalasia
Sammanfattning : .... LÄS MER
4. Instruction at heart. Activity-theoretical studies of learning and development in coronary clinical work
Sammanfattning : The aim of the thesis is to study the role of instruction in the interconnection of instruction-learning-development. The thesis consists of six empirical papers and a summing-up and perspectivizing introductory paper. LÄS MER
5. Ion channels and electrical activity in vascular smooth muscle: Effects of calcium store depletion, cholesterol and cholesterol-lowering drugs
Sammanfattning : Smooth muscle cells (SMCs) in the vessel wall contract to regulate blood flow and pressure, a function essential for normal circulation through tissues. On the other hand, migration and proliferation of SMCs are important factors in vascular disease, such as atherosclerosis and restenosis following surgical dilatation. LÄS MER
