Background: Transcranial Ultrasound Stimulation (tUS) is an emerging technique that uses ultrasonic waves to noninvasively modulate brain activity. As with other forms of non-invasive brain stimulation (NIBS), tUS may be useful for altering cortical excitability and neuroplasticity for a variety of research and clinical applications. The effects of tUS on cortical excitability are still unclear, and further complications arise from the wide parameter space offered by various types of devices, transducer arrangements, and stimulation protocols...

Tongue is one of the most common subsites involved by oral cancer. Improved surgical care and adjuvant therapy, along with better rehabilitation has significantly improved long-term survival and quality of life in patients with oral cancer. Primary surgical treatment is the preferred modality of treatment in cancers of the oral tongue. Although the surgical techniques have remained unchanged, various devices have been used to aid primary tumour resection, with a view to reduce bleeding and scarring. The purpose of this study is to compare resection of oral tongue tumours using ultrasonic coagulation device with conventional electrodiathermy...

INTRODUCTION AND HYPOTHESIS: No measurements are available for diagnosing the extent of obstetric lacerations. The primary aim of this study was to evaluate the relation between the anovaginal distance (AVD) measured with transperineal ultrasound immediately after delivery and external anal sphincter injury. A secondary aim was to assess whether the palpated perineal thickness was associated with the AVD. METHODS: A prospective observational study of 150 primiparous women at the University Hospital, Linköping, Sweden...

BACKGROUND: Primary prevention of cardiovascular disease often fails because of poor adherence among practitioners and individuals to prevention guidelines. We aimed to investigate whether ultrasound-based pictorial information about subclinical carotid atherosclerosis, targeting both primary care physicians and individuals, improves prevention. METHODS: Visualization of asymptomatic atherosclerotic disease for optimum cardiovascular prevention (VIPVIZA) is a pragmatic, open-label, randomised controlled trial that was integrated within the Västerbotten Intervention Programme, an ongoing population-based cardiovascular disease prevention programme in northern Sweden...

BACKGROUND: Imaging tests are one of the most sophisticated types of diagnostic tools used in health care, yet there are concerns that imaging is overused. Currently, tests are typically evaluated and implemented based on their accuracy, and there is limited knowledge about the range of patient-centered outcomes (PCOs) that imaging tests may lead to. This study explores patients' experiences and subsequent outcomes of imaging tests most notable to patients. METHODS: Adult patients from four primary care clinics who had an x-ray, CT, MRI, or ultrasound in the 12 months before recruitment participated in a single semistructured interview to recount their imaging experience...

OBJECTIVES: Ultrasound guided peripheral intravenous catheters (USPIV) are frequently utilized in the Emergency Department (ED) and lead to reduced central venous catheter (CVC) placements. USPIVs, however, are reported to have high failure rates. Our primary objective was to determine the proportion of patients that required CVC after USPIV. Our secondary objective was to determine if classic risk factors for difficult vascular access were predictive of future CVC placement. METHODS: We performed a retrospective review for patients treated at a large academic hospital...

BACKGROUND: Right iliac fossa abdominal pain is a common reason for emergency ward admissions, its etiology is difficult to diagnose. It can be facilitated by an imaging examination, such as a Computerized Tomography scan which exposes the patient to ionizing radiation and implies delays. A bedside ultrasound performed by emergency physicians could avoid these issues. The aim of our study was to assess the performance of ultrasound carried out at the patient's bedside by an emergency physician compared with a clinical-laboratory examination for the diagnosis of a surgical pathology in right iliac fossa pain...

Previous studies have suggested a decline in positivity of stress cardiac imaging based on regional wall motion abnormalities (RWMA). To assess the rate of RWMA positivity of stress echocardiography (SE) over 3 decades in the same primary care SE lab. We retrospectively assessed the rate of SE positivity in 7626 SE tests (dipyridamole in 5053, dobutamine in 2496, exercise in 77) in consecutive patients with known or suspected coronary artery disease and /or heart failure who performed SE in a primary care referral center from April 1991 to May 2018...

PURPOSE: Ultrasound can be used to non-invasively and rapidly examine airway conditions, but vocal cord visualization with the traditional approaches is poor. Our aim was to compare the accuracies of front-side transverse-axis ultrasound (FTU), lateral-side longitudinal-axis ultrasound (LLU), and the combination of both approaches for vocal cord movement disorder diagnoses (e.g., vocal cord paralysis or arytenoid cartilage dislocation). METHODS: We compared FTU, LLU, and the combination of both methods for patients in the intensive care unit (ICU)...

Orofacial pain can often be the chief complaint of many systemic disorders. Cysticercosis involving the lateral pterygoids may cause limitation of mouth opening and may mimic clinical symptoms of a temporomandibular disorder. A 37-year-old female presented with 1-month-old complaint of limited mandibular range of motion. She reported a similar episode a year earlier and was diagnosed with a temporomandibular joint disorder by her primary dentist. Comprehensive intra- and extra-oral examinations were performed, which revealed a limitation of mouth opening accompanied by mild limitation of contralateral excursion...

BACKGROUND: Medical treatment for acute heart failure (AHF) has not changed substantially over the last four decades. Emergency department (ED)-based evidence for treatment is limited. Outcomes remain poor, with a 25% mortality or re-admission rate within 30 days post discharge. Targeting pulmonary congestion, which can be objectively assessed using lung ultrasound (LUS), may be associated with improved outcomes. METHODS: BLUSHED-AHF is a multicenter, randomized, pilot trial designed to test whether a strategy of care that utilizes a LUS-driven treatment protocol outperforms usual care for reducing pulmonary congestion in the ED...

INTRODUCTION: Invasive respiratory support is a cornerstone of Critical Care Medicine, however, protocols for withdrawal of mechanical ventilation are still far from perfect. Failure to extubation occurs in up to 20% of patients, despite a successful spontaneous breathing trial (SBT). METHODS: We prospectively included ventilated patients admitted to medical and surgical intensive care unit in a university hospital in northern Mexico. At the end of a successful SBT, we measured diaphragmatic shortening fraction (DSF) by the formula: diaphragmatic thickness at the end of inspiration - diaphragmatic thickness at the end of expiration/diaphragmatic thickness at the end of expiration×100, and the presence of B-lines in five regions of the right and left lung...
