Filter by:The study will be done retrospectively.The aim of this study is to retrospectively examine the spinal pathologies of patients with a prediagnosis of spinal deformity and for whom spinal radiography is requested and to evaluate the clinical features of these patients.
Patients, ages between 18-70 years, who require central venous catheter will be enrolled for the study. Central venous catheter will be inserted using patient's height formula by Seldinger technique. Anterioposterior chest radiography will be used to assess the correct tip position. Catheters that are below the carina more than 1 cm, will be pulled back for repositioning. Catheters that are above the carina more than 1 cm, will be changed by another catheter. The investigators aim to evaluate the formula for correct tip positioning for central venous catheters
This study assesses the performance of radiographers in detecting radiological anomalies of the appendicular skeleton in emergency department. This is a retrospective study comparing the radiographers' diagnostic performance before and after dedicated training, assisted or not by artificial intelligence software. All performances will be evaluated and compared.
In this work, the investigators study the application of artificial intelligence systems on dental panoramic images for dental findings. An artificial intelligence system will be learned on an publicly available panoramic image dataset, and test against the investigators' local patient cohort as external test data. The investigators hypothesize the performance would be similar, if not identical to on the public data, and that the investigators' AI system is generalizable.
Knee osteoarthritis is a common disease that causes pain and loss of function. Total Knee Arthroplasty (TKA) is a frequently used surgical method in the treatment of severe knee osteoarthritis. The aim of this study was to investigate the effect of TKA on IL-6, TNF-α and IL-1β cytokine levels, pain intensity at rest and walking, knee joint valgity angle,malaligment, functional status and knee joint position sense.
Two diagnostic tools for TB screening in high risk groups need additional assessment: the AeoNose™, an 'electronic nose device' for breath sampling, and digital chest X-ray (CXR) with computer aided detection with CAD4TB® software. This study will systematically screen prisoners and its' employees for TB, test the diagnostic performance of AeoNose™ and CAD4TB (both individually and together) as a TB screening tool and and establish Mycobacterium tuberculosis epidemiology in Paraguayan prisons.
Children with cerebral palsy have an increased risk of hip dislocation, which is a painful and severe complication of cerebral palsy. The 20-years evaluation of the Swedish surveillance programme shows that hip dislocation in children with cerebral palsy can be prevented with regular clinical and radiographic examination and early intervention. We would like to determine the individual risk for hip displacement for Danish children with CP in The Danish Cerebral Palsy Follow-up Program. This could be a valuable clinical tool in deciding on further follow-up and treatment.
The aim is to describe the characteristics of children with cerebral palsy in Denmark. Furthermore, we want to focus on status of the children's hips.
The primary aim of the current study is to examine the accuracy of the C-distance or surface landmarks in determining the length of central venous catheter (CVC) that is required to place the catheter tip at the mid-superior vena cava (SCV) as confirmed by transesophageal echocardiography (TEE). A secondary aim is to derive an equation or formula to calculate the depth of the CVC that is required in order to have the catheter tip placed at the mid-SVC.
In patients under general anesthesia, the prevention of intraoperative hypotension to maintain blood pressure (BP) close to the initial blood pressure, i.e. before anesthesia, is essential to reduce the risk of death and improve surgical outcomes. Vasoactive agents are commonly used to correct this hypotension (Phenylephrine Ephedrine Noradrenaline). These three vasoconstrictors have specific effects on the afterload of the heart and can impair its function. The analysis of the left ventricular pressure-volume curve (PV Loop) allows continuous information on the post-charge state of the left ventricle and the changes induced by the vasoconstrictors to be observed. However, the investigators currently have no way of monitoring these effects. In clinical practice if these loops are obtained non-invasively they can be used in the evaluation of cardiac function of at-risk patients in perioperative and also in intensive care to allow therapeutic adaptation.
