1. 1. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

   Författare :Ulf Havelius; Oftalmologi (Malmö); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

   Sammanfattning : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.

3. 2. Characterisation and treatment of patients with port wine stains with special reference to the emotional impact

   Författare :Agneta Troilius; Dermatologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; capillary malformation; PWS; pulsed dye laser; laser doppler imager; ultrasound; psychosocial impact; depth; reflectance spectrophotometry; Dermatologi; venereologi; venereology; Dermatology;

   Sammanfattning : This thesis covers 12 years of experience in treating patients with congenital capillary malformations, so called port wine stains (PWS). The wide variation in treatment response to laser therapy has developed a profound need for the development of objective devises to measure treatment outcome, so that the maximum effectiveness of therapy can be achieved without unnecessary treatments.

4. 3. Negative Pressure Wound Therapy. Therapy Settings and Biological Effects in Peripheral Wounds

   Författare :Ola Borgquist; Lund Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Negative pressure wound therapy; vacuum-assisted closure; wound healing;

   Sammanfattning : Negative pressure wound therapy (NPWT) promotes wound healing through several mechanisms, e.g., altered periwound blood flow, mechanical deformation of the wound edge tissue, and drainage of excess fluid and debris. LÄS MER

5. 4. Skin fibrosis, internal organ involvement and auto antibodies in systemic sclerosis: longitudinal development and impact on survival

   Författare :Roger Hesselstrand; Reumatologi och molekylär skelettbiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; Skeleton; proteoglycan; pulmonary hypertension; organ involvement; auto antibodies; survival; systemic sclerosis; prognosis;

   Sammanfattning : Systemic sclerosis (SSc) is a connective tissue disease with a highly variable prognosis. Since new treatment strategies are emerging, there is a need for prognostic markers in order to help allocate patients to the optimal treatment. LÄS MER

7. 5. Negative Pressure Wound Therapy - Mechanisms of Action and Protecting Exposed Blood Vessels in the Wound Bed

   Författare :Erik Anesäter; Thoraxkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Negative pressure wound therapy; wounds; complications; experimental surgery; blood flow;

   Sammanfattning : NPWT has recently been associated with severe complications and bleeding when used in wounds with exposed blood vessels. The aims of this work were to investigate the mechanisms of action of NPWT and to explore the possibility of using thin plastic discs to protect exposed blood vessels in the wound bed during NPWT.
