  1. 1. Evaluation and treatment of pelvic organ prolapse : clinical, radiological and histopathological aspects

    Författare :Daniel Altman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bowel function; Cystodefecoperitoneography; Histology; Pelvic organ prolapse. Rectal prolapse; Rectocele; Safety; Xenograft;

    Sammanfattning : Objective: To assess the use of cystodefecoperitoneography (CDP) in clinical and radiological diagnosis of cystocele; to study the correlation between clinical and radiological findings at CDP and to evaluate if anatomical topography and structural abnormality corresponds to symptomatic presentation when assessing posterior vaginal wall prolapse; to evaluate if xenograft used at rectocele repair was associated with adverse clinical and histological inflammatory reactions; to prospectively examine if rectocele repair using xenograft is a safe method providing satisfactory clinical and symptomatical outcome; and to investigate the prevalence and risk factors of genital prolapse and urinary incontinence in female patients operated for rectal prolapse. Methods: The following methods were used: The Pelvic organ prolapse quantification system (POPQ), CDP, bowel function questionnaires, pelvic floor surveys, histological, histopathological and clinical inflammatory quantification.

  3. 2. Moderately preterm infants : studies on length of hospital stay and neonatal outcome

    Författare :Maria Altman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Objective: Moderately preterm infants account for a large proportion of admissions and bed-days in neonatal units. Determinants of length of hospital stay, contemporary measures of morbidity by gestational week and risk factors predicting neonatal morbidity have been poorly studied. LÄS MER

  4. 3. Multi-species systems in optical lattices : From orbital physics in excited bands to effects of disorder

    Författare :Fernanda Pinheiro; Jonas Larsson; Jani-Petri Martikainen; Ehud Altman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : In this thesis we explore different aspects of the physics of multi-species atomic systems in optical lattices. In the first part we will study cold gases in the first and second excited bands of optical lattices - the p and d bands. LÄS MER

  5. 4. A Segmented Silicon Strip Detector for Photon-Counting Spectral Computed Tomography

    Författare :Cheng Xu; Hans Bornefalk; Mats Danielsson; Ami Altman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photon counting; spectral computed tomography; silicon strip detector; ASIC; energy resolution; cadmium telluride; charge sharing; Monte Carlo simulation; synchrotron;

    Sammanfattning : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.
