1. Cardiac involvement in familial amyloidosis with polyneuropathy
Sammanfattning : Familial amyloidosis with polyneuropathy (FAP) is a neuropathic form of heredofamilial systemic amyloidosis. Clusters of patients have been reported predominantly from Portugal, Japan and Sweden. The present study examines the involvement of the heart in individuals with the Swedish variety of FAP. LÄS MER
2. Deposition and absorption of inhaled drugs
Sammanfattning : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.

3. Artificial neural networks classify myocardial perfusion images
Sammanfattning : In the studies of this thesis, a method for automated classification of myocardial perfusion images was successfully developed and evaluated. The results show that the method, based on artificial neural networks, was equally good, or even better than human experts. LÄS MER
4. Early parathyroidectomy in mild primary hyperparathyroidism: Effects on heart and bones
Sammanfattning : There is an ongoing controversy regarding how to take care of patients with mild primary hyperparathyroidism (PHPT). Some recommend surgical treatment at diagnosis, others just follow-up as long as there is no evidence of disease progression. LÄS MER
5. Secundum atrial septal defect in the adult. Clinical, haemodynamic and electrophysiological aspects
Sammanfattning : Atrial septal defect (ASD) is the most common congenital heart malformation diagnosed in adult life. In this thesis important clinical, haemodynamic and electrophysiological aspects of ASD in the adult are explored. LÄS MER
