1. 6. Incidentally detected adrenal lesions - radiological aspects

   Författare :Lilian Hammarstedt; Göteborgs universitet; []
   Nyckelord :Incidental finding; Adrenal incidentaloma; Adrenal Gland Neoplasm; Computed Tomography; Magnetic Resonance Imaging; Follow-up Studies; Oncology; Observer variation; Phantom Studies;

   Sammanfattning : Incidentally detected adrenal lesions (“adrenal incidentalomas”) have become a growing clinical problem due to increased and refined radiology methods. Autopsy studies show frequencies as high as 7-8% in the elderly. A large part of such lesions give no health problems but some can be related to hormone overproduction or malignant disease. LÄS MER

3. 7. Radiological evaluation of esophageal function in dysphagia with special emphasis on achalasia

   Författare :Mats Andersson; Göteborgs universitet; []
   Nyckelord :Achalasia; Dysphagia; Radiography; Barium esophagogram; Reproducibility of findings; Observer variation; Laparoscopic myotomy; Balloon dilatation; Esophageal neoplasms;

   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

4. 8. Low Back Pain : With Special Reference to Prevalence, Diagnosis, Treatment and Prognosis

   Sammanfattning : Objectives. Ascertain if there has been a secular trend in 3-months prevalence of casually reported back pain. Evaluate if such back pain predicts concurrent health as well as future sick leave, disability pension, hospitalization and survival. Study differences in diagnostic assessment and labelling between physicians. LÄS MER

5. 9. Ultrasound in the management of women with post-menopausal bleeding

   Sammanfattning : The aim of this thesis was to investigate how ultrasound can be used in the diagnostic work-up of women with post-menopausal bleeding (PMB) to optimise and individualise their management. The thesis is based on six studies comprising post-menopausal women with (Study I-VI) and without (Study VI) abnormal bleeding. LÄS MER
