Radiation effects on light scattering and cataract formation in the lenses of interventional radiologist and cardiologists
2014
Purpose There is little information about exposure to dosages below 500 mSv. This pilot study aimed at investigating the effects of low dose radiation on lens transparency in occupationally exposed interventional cardiologists and radiologists. Methods Physicians who have performed fluoroscopically guided procedures for at least 5 years were recruited in the areas of Cologne-Bonn and Rhine-Main together with their non-exposed colleagues. A questionnaire has been developed to estimate occupational exposure. Exclusion criteria comprised corticosteroid treatment, radiotherapy, chemotherapy and glaucoma. Changes in lens transparency and cataract formation were determined by slit lamp microscopy…
Association of Birth Weight with Central and Peripheral Corneal Thickness in Adulthood-Results from the Population-Based German Gutenberg Health Stud…
2021
Low birth weight (BW) is associated with altered ocular geometry such as a steeper corneal shape in adulthood. However, it is unclear whether low birth weight affects corneal thickness development in the center or periphery in adulthood which may contribute to ocular disease. The purpose of this study was to investigate corneal thickness in former low birth weight individuals in adulthood. Methods: The German Gutenberg Health Study is a prospective, population-based study in which every participant (age range 40–80 years) was measured with Scheimpflug imaging (Pentacam HR, Oculus Optikgeräte GmbH, Wetzlar, Germany). BW was collected by self-reports. The relationship between birth weight and…
Postoperative Lens Position Preoperatively Determined by Scheimpflug Photography
1999
The position of the artificial lens has an important influence on refractive power calculation. We compared the position of the crystalline lens with that of the artificial lens after cataract surgery by means of Scheimpflug photography. A difference in position of approximately 0.8 mm in the anterior direction could be determined.
Objective assessment of cataract: Comparison between the Lens Opacities Classification System III and a Scheimpflug camera
2015
Purpose Develop an automatic system for cataract classification using the Sirius Scheimpflug for both nuclear and cortical cataract. Methods Scheimpflug images were taken using the Sirius system in 50 patients with nuclear and/or cortical cataract (mean age 69 ± 9.2 years). The nuclear opacity (NO) and cortical opacity was graded by an ophthalmologist according to the Lens Opacities Classification System (LOCSIII) by comparing the slit-lamp image with the LOCS's standard nuclear images. A custom-made MATLAB program was used to calculate the pixel intensity value within a region of interest (ROI) of the nucleus and to calculate the percentage of opaque pixels in the cortex. Results Eighty-ni…
Maternal risk factors of urinary incontinence during pregnancy and postpartum: A prospective cohort study
2021
Highlights • Urinary incontinence after delivery affects every fifth woman. • Urinary incontinence before pregnancy is a risk factor of postpartum incontinence. • Primiparous women are at a greater risk of urinary incontinence after birth.
Enhancing memory performance with rTMS in healthy subjects and individuals with Mild Cognitive Impairment: the role of the right dorsolateral prefron…
2012
A debated question in the literature is the degree of anatomical and functional lateralization of the executive control processes subserved by the dorsolateral prefrontal cortex (DLPFC) during recognition memory retrieval. We investigated if transient inhibition and excitation of the left and right DLPFC at retrieval by means of repetitive transcranial magnetic stimulation (rTMS) modulate recognition memory performance in 100 healthy controls (HCs) and in 8 patients with Mild Cognitive Impairment (MCI). Recognition memory tasks of faces, buildings and words were used in different experiments. rTMS-inhibition of the right DLPFC enhanced recognition memory of verbal and non verbal material in…
Medisinsk avstandsoppfølging for pasienter med epilepsi : En kvalitativ studie om pasienter med epilepsi sine opplevelser, erfaringer og tanker om ny…
2020
Master's thesis in Health informatics (HSI500) Background There is an increasing focus on the use of medical distance monitoring to improve the quality of patient care and increase the effectiveness of health care. Digital PRO-based solution is a new service for patients with epilepsy. The digital form the patient fills out is used as the basis for outpatient follow-up. Purpose The purpose of this study is to contribute knowledge to whether patients with epilepsy experience benefits of medical distance monitoring. The problem statement in the study was: "What experiences and thoughts do patients with epilepsy have about the utility of medical distance follow-up?" Selection and methodologyTh…
Fastlegers informasjonsbehov ved medisinsk avstandsoppfølging : En kvalitativ studie
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Bakgrunn:For å møte den fremtidige økningen i forekomsten av ikke-smittsomme kroniske sykdommerhar Norge prøvd utmedisinsk avstandsoppfølging siden2016. Resultatene så langt viser en økt trygghet, samt følelse av oppfølging og kontroll over egen helse hos pasientene. Det understrekes at det å involvere fastleger i tjenestene har vært utfordrende(Helsedirektoratet, 2018a). Videreutprøvingble startet opp i 2018 og er planlagt å fortsette til og med2021. Hensikt:Formålet med denne masteroppgaven er å bidra med kunnskap om hvordan IKT best mulig kan understøtte fastlegenes tiltenkte rolle som koordinator i medisinsk a…
