16. Persistent geotropic nystagmus : a different kind of cupula pathology
Sammanfattning : In patients with positional vertigo a persistent positional direction-changing nystagmus (PDCN) of apogeotropic direction (a-PDCN) in the supine yaw plane has been described earlier 1-5. It has been suggested that the cupula in the lateral semicircular canal has a higher specific weight than the surrounding endolymph making the cupula sensitive to gravity. LÄS MER
17. Aspects of lung mechanics during mechanical ventilation
Sammanfattning : Background: One of the most common diagnoses in the intensive care unit is acute respiratory failure. In its most severe form it is called acute respiratory distress syndrome and often requires mechanical ventilation. LÄS MER
18. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern
Sammanfattning : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

19. Posture and brain function in dementia. A study with special reference to orthostatic hypotension
Sammanfattning : Orthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. LÄS MER
20. Low rectal cancer : aspects of surgical techniques and treatment results
Sammanfattning : Rectal cancer is the 7th most common form of cancer in Sweden, both for men and women. About one third of all patients diagnosed with rectal cancer have a low tumour (i.e. 0-5 cm from the anal verge). LÄS MER
