Filter by:The overall purpose of this study is to establish an ultrasound technique to aid in oral and dental examination of soft and hard tissues. Ultrasound is currently not used in Dentistry and associated oral examinations and its usefulness for clinical practice will be explored. This study will investigate the use of ultrasonic imaging for planning and placing dental implants, as well as evaluate the use of ultrasonic imaging for monitoring marginal bone loss around dental implants.
Pulmonary complications are frequent in cardiac surgery, representing an important cause of morbidity, prolongation of hospital stay and need for repeated examinations.Chest X-rays are done routinely and even multiple times to detect such complications.Lung ultrasonography is an alternative test to detect pulmonary complications that can be done easily on bedside. Regularly done Chest X-ray exposes patient to ionizing radiation which can be reduced with ultrasonography. Lung ultrasound is gaining popularity in recent years as a non-invasive,radiation-free tool for the diagnosis of various acute and chronic pulmonary diseases due to its bedside convenience, accuracy, and free of radiation.There is increasing evidence to support the use of Lung ultrasound in acute care setting and post-cardiac surgical patients are also considered critically ill. The purpose of this study is to compare diagnostic performance of lung ultrasound in comparison to chest X-ray to detect pulmonary complication after cardiac surgery in children.
Headache affects the daily quality of life of patients. It has been reported that headaches may be associated with neck muscles, neck movements and trigger points in the neck Drug and non-drug treatments can be used today in the treatment of headaches. Various physical therapies are applied to cranial and cervical regions in non-drug therapies. Therapeutic ultrasound, Transcutaneous Electrical Nerve Stimulation (TENS), Hotpack and manipulation are some of them.This is a randomised placebo- controlled trial to determine the efficacy of the therapeutic ultrasound in the treatment of migraine.
Findings in neuroscientific research show that the environment one lives in has measurable effects on brain morphology and functioning. Human exposure to airborne infra- and ultrasound has been constantly increasing during the last decades. For instance, the European Renewable Energy Directive, established in 2009, lead to an increased use of wind turbines, generating infrasound. The EU Directive states that until 2020 a 20% of the EUs' total energy needs is to be generated with renewables, therefore the current infrasound load in the European environment will increase further. Similarly, ultrasound is ubiquitous in the modern public environment, emitted from public address systems, animal repellents, industrial machines, even toothbrushes. The present study aims to investigate potential long-term effects of exposure to infra- and ultrasound on subjective well-being, cognitive and brain functioning, as well as on brain structure. The study will apply a randomized-(placebo) controlled single-blind approach to investigate this subject.
Percutaneous nephrolithotomy (PNL) is frequently used today for renal stones. percutaneous nephrolithotomy (PNL) procedure has become the treatment of choice for many patients with symptomatic renal stones . Patients undergoing PNL suffer from acute postoperative pain, despite a multimodal analgesic regime. This is a randomised controlled trial efficacy of the anterior Quadratus Lumborum Block (QLB) in terms of analgesic efficacy in patients who undergo percutaneous nephrolithotomy.
This study in part of a larger cohort study (clinical trials ID number: NCT03375333) that examine the use of ultrasound in general practice. In the present study patient experiences, with use of ultrasound in the consultation at the general practitioners office, will be explored through a questionnaire.
This study explores how Point of Care Ultrasound (POC-US) is used in general practice in Denmark and how it affects the diagnostic process and treatment of patients. Twenty general practitioners (GPs) will register information each time they use POC-US during a one month period. The information will include indications and frequencies of the performed POC-US examinations, change in tentative diagnosis, plan, and treatment before and after the use of POC-US in relation to confidence in the tentative diagnosis, findings and quality of the POC-US examination. This is an observational study without any intervention.
Analgesia following tympanomastoid surgery is critical for the prevention of postoperative . There are very few regional anesthesia methods used to achieve this goal.
Point-of-care ultrasound (POCUS) has been found to be useful for aiding in the prediction of fluid responsiveness. It is unknown if trainees can effectively utilize this tool to improve their assessment of fluid responsiveness. In this prospective, observational study, pulmonary and critical care fellows are asked to make 2 assessments of fluid responsiveness in adults with shock: (1) based on clinical exam alone (Clinical) and (2) after performing a POCUS (Clinical + US). The accuracy of their pre- and post-ultrasound assessments are compared using a bioreactance monitor and passive leg raise test as the gold standard of fluid responsiveness in this study.
This preliminary study investigates in patients with possible clinical diagnosis of pneumonia, clues and biomarker assessed at Emergency Department (ED) triage, potentially predicting detection of lung consolidation by Thoracic-ultrasound (TUS) and/or by Chest-X-Rays. Cough and high admission CRP levels will be defined according to the cutoff defined by ROC analysis, will be challenged if independently associated with TUS lung consolidation detection High level of the chosen biomarker, and any of the considered symptoms, in otherwise not extremely critical patients (CURB65≤3), should prompt to immediate confirm by TUS, during the physical examination. This may limit the need of further radiological investigations allowing targeted workup.
