Úlcera eosinofílica lingual: un reto diagnóstico de patogénesis controvertida
2013
ResumenLa úlcera eosinofílica, también conocida como granuloma ulcerativo traumático con eosinofilia estromal, es una infrecuente y benigna lesión ulcerativa de la mucosa oral que presenta una evolución persistente, planteando a menudo diferentes diagnósticos clínicos diferenciales. Su diagnóstico se establece solo a partir del estudio histopatológico, si bien su morfología presenta a menudo características que pueden sugerir al patólogo la existencia de un proceso linfoproliferativo, traduciendo una patogénesis lesional controvertida todavía no bien aclarada.Comunicamos una observación clínico-patológica de úlcera eosinofílica afectando a una mujer de 76 años de edad. La lesión, de 2,5cm d…
The Increased Mortality Rate with Lower Incidence of Traumatic Brain Injury during the COVID-19 Pandemic: A National Study
2022
Background: the COVID-19 pandemic with the following lockdown strategies have affected virtually all aspects of everyday life. Health services all over the world faced the crisis on an unprecedented scale, hampering timely care delivery. The present study was designed to assess the impact of the COVID-19 outbreak on the incidence and treatment of traumatic brain injuries in Poland. Methods: the data on hospital admissions with traumatic brain injuries as the primary diagnosis were extracted from the National Health Fund of Poland. For the purpose of this study, the search was limited to four relevant diagnosis-related groups. The overall in-house mortality was calculated. Results: there wer…

Correction to: Depletion of regulatory T cells increases T cell brain infiltration, reactive astrogliosis, and interferon-γ gene expression in acute …
2019
Traumatic brain injury (TBI) is a major cause of death and disability. T cells were shown to infiltrate the brain during the first days after injury and to exacerbate tissue damage. The objective of this study was to investigate the hitherto unresolved role of immunosuppressive, regulatory T cells (Tregs) in experimental TBI."Depletion of regulatory T cell" (DEREG) and wild type (WT) C57Bl/6 mice, treated with diphtheria toxin (DTx) to deplete Tregs or to serve as control, were subjected to the controlled cortical impact (CCI) model of TBI. Neurological and motor deficits were examined until 5 days post-injury (dpi). At the 5 dpi endpoint, (immuno-) histological, protein, and gene expressio…
Pathophysiology of traumatic brain injury.
2007
The knowledge of the pathophysiology after traumatic head injury is necessary for adequate and patient-oriented treatment. As the primary insult, which represents the direct mechanical damage, cannot be therapeutically influenced, target of the treatment is the limitation of the secondary damage (delayed non-mechanical damage). It is influenced by changes in cerebral blood flow (hypo- and hyperperfusion), impairment of cerebrovascular autoregulation, cerebral metabolic dysfunction and inadequate cerebral oxygenation. Furthermore, excitotoxic cell damage and inflammation may lead to apoptotic and necrotic cell death. Understanding the multidimensional cascade of secondary brain injury offers…
Ex post-facto study of long-term stress in a sample of adoptees
2015
In this work we study the impact of relinquishment and the adoption process in posttraumatic symptoms and stressful life events in a group of 55 adults that were adopted as children after the Spanish Civil War (1936-1939). The effects of institutionalization, maltreatment and traumatic revelation of the adopted status have also been studied. No significant differences were found between institutionalized and non-institutionalized adoptees in posttraumatic symptomatology and stressful life events frequency. However, maltreated adoptees scored significantly higher in intrusion, arousal and stressful life events frequency than non-maltreated. Similar differences were found in the comparison be…
Extubation in neurocritical care patients: the ENIO international prospective study
2022
Purpose: Neurocritical care patients receive prolonged invasive mechanical ventilation (IMV), but there is poor specific information in this high-risk population about the liberation strategies of invasive mechanical ventilation. Methods: ENIO (NCT03400904) is an international, prospective observational study, in 73 intensive care units (ICUs) in 18 countries from 2018 to 2020. Neurocritical care patients with a Glasgow Coma Score (GCS) ≤ 12, receiving IMV ≥ 24 h, undergoing extubation attempt or tracheostomy were included. The primary endpoint was extubation failure by day 5. An extubation success prediction score was created, with 2/3 of patients randomly allocated to the training cohort …
The aftermath of resilience in the global world.
2018
Just as there is an aftermath of trauma, there is reason to think of an aftermath of resilience, different from the resilience capacities developed after a trauma. The aftermath of resilience reflects the ability to activate resilient memory in response to traumatic memory in order to rebuild oneself. This is a major challenge for the global mental health of our fragile societies. The challenge is significant for France, Europe and the world. Beyond the overuse of the word resilience in scientific literature and the media, it contributes to the methodology, epistemology and politics of resilience.
Overview of Positive Psychology in Latin-American Countries
2014
This chapter aims to outline the dissemination of Positive Psychology (PP) in Latin America and provides an overview of the present book. In the past decade, PP was introduced in Argentina by Maria Martina Casullo. Since 2006, Positive Psychology Ibero-American Meetings have been held annually, involving the majority of Latin American countries, especially from South America. Abstract books of these meetings and Latin-American indexed journals were the basis to identify the impact of PP in the southern region. Four basic trends were found: (1) the most frequently studied topics were psychological well-being, interpersonal relationships and psychotherapeutic interventions; (2) there was a la…
<title>Noninvasive detection of intracerebral hemorrhage using near-infrared spectroscopy (NIRS)</title>
1998
Intracerebral Hemorrhage (IH) is an important cause of secondary brain injury in neurosurgical patients. Early identification and treatment improve neurologic outcome. We have tested Near Infrared Spectroscopy (NIRS) as an alternative noninvasive diagnostic tool compared to CT-Scans to detect IH. We prospectively studied 212 patients with neurologic symptoms associated with intracranial pathology before performing a CT-scan. NIRS signals indicated pathologies in 181 cases (sensitivity 0.96; specificity 0.29). In a subgroup of subdural hematomas NIRS detected 45 of 46 hematomas (sensitivity 0.96; specificity 0.79). Identification of intracerebral hemorrhage using NIRS has the potential to al…
