Palatal atypical histiocytic granuloma
2009
In this report, we examine a clinical entity called atypical histiocytic granuloma (AHG), which is characterized by ulceroproliferative lesions that clinically simulate a squamous cell carcinoma or specific granulomatous lesions. AHG histologically shows a histiocytic proliferation and is characterized by specific mitotic activity, which has the potential to be confused with malignant processes of a lymphoid origin. There are few cases reported in the literature, and an adequateknowledge of the process is required in order to avoid a misdiagnosis, especially as regards malignant processes. To our knowledge, a case of this type of lesion in the palate has not yet been described. We present a…
Transforming Experience: The Potential of Augmented Reality and Virtual Reality for Enhancing Personal and Clinical Change
2016
During life, many personal changes occur. These include changing house, school, work, and even friends and partners. However, the daily experience shows clearly that, in some situations, subjects are unable to change even if they want to. The recent advances in psychology and neuroscience are now providing a better view of personal change, the change affecting our assumptive world: (a) the focus of personal change is reducing the distance between self and reality (conflict); (b) this reduction is achieved through (1) an intense focus on the particular experience creating the conflict or (2) an internal or external reorganization of this experience; (c) personal change requires a progression…
A case of meningitis due to Achromobacter xylosoxidans denitrificans 60 years after a cranial trauma
2011
Import JabRef | WosArea Research and Experimental Medicine; International audience; Background: Achromobacter xylosoxidans (AX) is a non-fermentative aerobic Gram-negative bacillus. It is an opportunistic pathogen and the causative agent of various infections. We report an original case of late posttraumatic meningitis due to AX denitrificans. Case Report: An 83-year-old man was hospitalized for acute headache, nausea and vomiting. The emergency brain computer tomography (CT) scan did not reveal any anomaly. In his medical history, there was an auditory injury due to a cranial trauma incurred in a skiing accident 60 years earlier. Cytobiochemical analysis of the cerebrospinal fluid (CSF) re…
Factors affecting peak impact force during soccer headers and implications for the mitigation of head injuries
2020
It has been documented that up to 22% of all soccer injuries are concussions. This is in part due to players purposely using their head to direct the ball during play. To provide a more complete understanding of head trauma in soccer athletes, this study characterized the effects of four soccer ball characteristics (size, inflation pressure, mass, velocity) on the resulting peak impact force as it relates to the potential for incurring neurophysiological changes. A total of six hundred trials were performed on size 4 and 5 soccer balls as well as a novel lightweight soccer ball. Impact force was measured with a force plate and ball velocity was determined using motion capture. These data we…
Protocol for Low-level laser therapy in traumatic ulcer after troncular anesthesia: Case report in pediatric dentistry
2020
The aim of this study was to report a protocol of use for low-level laser therapy (LLLT) in traumatic ulcer in the lower lip after inferior alveolar nerve block anesthesia (IANBA). A 3-year-old patient, male, undergoing treatment of carious lesions was submitted to an indirect pulp capping in tooth 74 under IANBA. The procedure was completed without intercurrences, but on next day, the child presented extensive traumatic ulcer in the left lower lip, with complaint of pain. Two sequential applications with LLLT were applied in punctual mode under pressure around the lesion. After 1 week, the mother reported significant improvement. After 30 days, the lesion was fully healed. In conclusion, L…
Caspase-dependent cell death involved in brain damage after acute subdural hematoma in rats
2006
Abstract Traumatic brain injury is associated with acute subdural hematoma (ASDH) that worsens outcome. Although early removal of blood can reduce mortality, patients still die or remain disabled after surgery and additional treatments are needed. The blood mass and extravasated blood induce pathomechanisms such as high intracranial pressure (ICP), ischemia, apoptosis and inflammation which lead to acute as well as delayed cell death. Only little is known about the basis of delayed cell death in this type of injury. Thus, the purpose of the study was to investigate to which extent caspase-dependent intracellular processes are involved in the lesion development after ASDH in rats. A volume o…
The Impact of the COVID-19 Emergency on the Quality of Life of the General Population
2022
COVID-19 is a pandemic that has forced many states to declare restrictive measures in order to prevent its wider spread. These measures are necessary to protect the health of adults, children, and people with disabilities. Long quarantine periods could cause an increase in anxiety crises, fear of contagion, and post-traumatic stress disorder (frustration, boredom, isolation, fear, insomnia, difficulty concentrating). Post-traumatic stress disorder (PTSD) is a condition that can develop in subjects who have been or have witnessed a traumatic, catastrophic, or violent event, or who have become aware of a traumatic experience that happened to a loved one. In fact, from current cases, it emerge…
Worsening of Preexisting Psychiatric Conditions During the COVID-19 Pandemic
2020
Objectives: To ascertain factors associated with worsening of psychiatric conditions during the coronavirus disease 2019 (COVID-19) pandemic. Methods: This study anonymously examined 2,734 psychiatric patients worldwide for worsening of their preexisting psychiatric conditions during the COVID-19 pandemic. An independent clinical investigation of 318 psychiatric patients from United States was used for verification. Results: Valid responses mainly from 12 featured countries indicated self-reported worsening of psychiatric conditions in two-thirds of the patients assessed that was through their significantly higher scores on scales for general psychological disturbance, posttraumatic stress …
Plasma Hyperosmolality Prolongs QTc Interval and Increases Risk for Atrial Fibrillation in Traumatic Brain Injury Patients
2020
Introduction: Hyperosmotic therapy with mannitol is frequently used for treatment cerebral edema, and 320 mOsm/kg H2O has been recommended as a high limit for therapeutic plasma osmolality. However, plasma hyperosmolality may impair cardiac function, increasing the risk of cardiac events. The aim of this study was to analyze the relation between changes in plasma osmolality and electrocardiographic variables and cardiac arrhythmia in patients treated for isolated traumatic brain injury (iTBI). Methods: Adult iTBI patients requiring mannitol infusion following cerebral edema, and with a Glasgow Coma Score below 8, were included. Plasma osmolality was measured with Osmometr 800 CLG. Spatial Q…
