A systematic approach to medical decision-making of uncommon clinical pictures: A case of ulcerative skin lesions by palm tree thorn injury and a one…
2005
In clinical practice, the clinician is challenged with symptoms and/or signs at times apparently insoluble by diagnostic and/ or therapeutic means. We propose that in these cases, we have to use an EBM approach in which evidence may be looked up in every available clinical report and bibliographic databases are used for searching that evidence. We report on a case of ulcerative skin lesions apparently insoluble by expert dermatologists following a conventional diagnostic and therapeutic process. We use this case report for illustrating a systematic approach to resolve diagnostic and therapeutic questions using a bibliographic database search (like MEDLINE and EMBASE). Both a systematic appr…
A Randomized-Controlled Study of Intrathecal Versus Epidural Thoracic Analgesia in Patients Undergoing Abdominal Cancer Surgery
2008
Background. We sought to determine the effectiveness of continuous intrathecal thoracic analgesia (ITA) in comparison with continuous epidural thoracic analgesia (ETA) for the management of postoperative pain after abdominal cancer surgery in a randomised controlled study. Materials and methods. Catheters were inserted at T8-10 level for both techniques. Sixty patients were randomized to receive ITA providing levobupivacaine 0.25%, at 0.5-0-7 ml/h, associated with a single bolus of morphine 0.15 mg, or ETA with levobupivacaine 0.25% 4-6 ml/h and a single bolus of epidural morphine 2-3 mg. Data were collected before discharging from recovery room to the surgical ward, 1, 2, 3, 8, 12, 24 h, a…
Recognition of root canal orifices at a distance – a preliminary study of teledentistry
2011
The remote recognition of root canal orifices was tested on 50 images of endodontically accessed teeth acquired with an intra-oral camera. The images were stored on a laptop computer and were presented to 20 observers who marked the visible canal orifices using software which stored the canal locations in standard files. The marked positions were verified on histological slices. In 87% of the cases, the canal locations were marked correctly. Inter-observer reliability depended on the location of the reviewed root canal (kappa = 0.44–0.77). The detection rate was related to the professional experience of the observers. The maximum proportion of accurate detections was found for the observer…
Validation of the Comprehensive Feeding Practices Questionnaire with parents of 10-to-12-year-olds
2011
Abstract Background There is a lack of validated instruments for quantifying feeding behavior among parents of older children and adolescents. The Comprehensive Feeding Practices Questionnaire (CFPQ) is a self-report measure to assess multiple parental feeding practices. The CFPQ is originally designed for use with parents of children ranging in age from about 2 to 8 years. It is previously validated with American and French parents of children within this age range. The aim of the present study was to adapt and test the validity of this measure with parents of older children (10-to-12-year-olds) in a Norwegian setting. Methods A sample of 963 parents of 10-to-12-year-olds completed a Norwe…
A study protocol for applying the co-creating knowledge translation framework to a population health study
2013
Background: Population health research can generate significant outcomes for communities, while Knowledge Translation (KT) aims to expressly maximize the outcomes of knowledge producing activity. Yet the two approaches are seldom explicitly combined as part of the research process. A population health study in Port Lincoln, South Australia offered the opportunity to develop and apply the co-KT Framework to the entire research process. This is a new framework to facilitate knowledge formation collaboratively between researchers and communities throughout a research to intervention implementation process. Design: This study employs a five step framework (the co-KT Framework) that is formulate…
Mixed predictability and cross-validation to assess non-linear Granger causality in short cardiovascular variability series
2006
A method to evaluate the direction and strength of causal interactions in bivariate cardiovascular and cardiorespiratory series is presented. The method is based on quantifying self and mixed predictability of the two series using nearest-neighbour local linear approximation. It returns two causal coupling indexes measuring the relative improvement in predictability along direct and reverse directions, and a directionality index indicating the preferential direction of interaction. The method was implemented through a cross-validation approach that allowed quantification of directionality without constraining the embedding of the series, and fully exploited the available data to maximise th…

Use of health care services among Syrian refugees migrating to Norway: a prospective longitudinal study
2021
Abstract Background Understanding the differential utilization of healthcare services is essential to address the public health challenges. Through the migration process, refugees move from one set of health risk factors to another and can face multiple healthcare challenges along their journey. Yet how these changing risk factors influence refugees’ use of health care services is poorly understood. Methods A longitudinal survey assessing health care utilization of 353 adult Syrian refugees was conducted; first in a transit setting in Lebanon and after one year of resettlement in Norway. The main outcomes are the utilization of general practitioner services, emergency care, outpatient and/o…
A classification study of kinematic gait trajectories in hip osteoarthritis
2014
The clinical evaluation of patients in hip osteoarthritis is often done using patient questionnaires. While this provides important information it is also necessary to continue developing objective measures. In this work we further investigate the studies concerning the use of 3D gait analysis to attain this goal. The gait analysis was associated with machine learning methods in order to provide a direct measure of patient control gait discrimination. The applied machine learning method was the support vector machine (SVM). Applying the SVM on all the measured kinematic trajectories, we were able to classify individual patient and control gait cycles with a mean success rate of 88%. With th…
Elements of Significance Testing with Equivalence Problems
1991
AbstractThe paper outlines an approach to the general methodological problem of equivalence assessment which is based on the classical theory of testing statistical hypotheses. Within this frame of reference it is natural to search for decision rules satisfying the same criteria of optimality which are customarily applied in deriving solutions to one- and two-sided testing problems. For three standard situations very frequently encountered in medical applications of statistics, a concise account of such an optimal test for equivalence is presented. It is pointed out that tests based on the well-known principle of confidence interval inclusion are valid in the sense 1 of guaranteeing the pre…
