Eosinophilic ulcer tongue: a diagnostic challenge controversial pathogenesis
2013
La 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 2,5 cm de diá…
Do Androids Have Nightmares About Electric Sheep? Science Fiction Portrayals of Trauma Manifestations in the Posthuman Subject in Frankenstein, Do An…
2018
This essay draws upon the contention that posthuman subjects, such as androids, clones, and robots, can experience psychological trauma. The aim of the paper is to examine this notion in three science fiction texts: Mary Shelley’s Frankenstein , Philip K. Dick’s Do Androids Dream of Electric Sheep? , and Ursula Le Guin’s short story ‘Nine Lives’. What these narratives illustrate is that trauma manifestations contribute to a disruption of ontological frameworks that regard categories such as ‘human’ and ‘non-human’ as permanent and distinct. As a result, it might be argued that these texts undermine anthropocentrism and invite a reconceptualising around the term ‘human’, but also around trau…
Questioning the Images of Atrocity: An Introduction
2015
The images of atrocity, either analog or digital, are always the trace of an encounter between the gaze of a photographer or a cameraman and a human being suffering from the painful effects of man-made violence. The archive images resulting from such an encounter raise some inevitable questions: who took them and for what purpose? Is it possible to retrace the process that led to these shots? What do they hide behind what the eye can see? Owing to their defective nature and the changes they have endured throughout history, these images strongly contribute to shape collective memory by becoming real sites of memory for ethnic or national communities. Therefore, the archive of human pain, enc…
Tūjas ķieģeļu fabrika sociālajā atmiņā: Tūjas iedzīvotāju atmiņstāstu un preses publikāciju analīze
2017
Bakalaura darba tēma ir Fabrika sociālajā atmiņā: Tūjas iedzīvotāju atmiņstāstu un preses publikāciju analīze. Tūjas ķieģeļu fabrikas darbinieku un tā laika līdzgaitnieku atmiņas veido viņu kopīgo sociālo atmiņu. Grupas locekļi papildina viens otra sacīto, tādējādi veidojot daudzpusīgāku kopīgo sociālo atmiņu. Darba mērķis ir izpētīt, kāda ir Tūjas iedzīvotāju sociālā atmiņa, atminoties fabriku, laiku, kad tā darbojās, dzīvi pēckara laikā. Kā arī izpētīt pieejamās preses publikācijas par Tūjas ķieģeļu fabriku un rūpniecību Padomju laikā. Darba teorētiskajā daļā detalizēti un daudzpusīgi raksturota "sociālās atmiņas", "ikdienas dzīves" un "traumas" koncepti. Pētījumā noskaidrots, kas veidoja…
The outcomes of Ilizarov treatment in aseptic nonunions of the tibia stratified by treatment strategies and surgical techniques.
2020
Abstract INTRODUCTIONNonunions of the tibia, particularly those located in the distal third of the bone, are relatively common in clinical practice. There is no gold standard for the treatment of nonunions of the tibia. The purpose of our study was to assess the results of treatment with the Ilizarov method in patients with aseptic nonunions of the tibia, depending on the employed treatment strategies and surgical techniques.MATERIALS AND METHODSA total of 75patients with Ilizarov treatment of aseptic nonunions of the tibia were evaluated in the study. The patients’s mean age at the beginning of treatment was 46years.The mean follow-up period was 10years and 11months.The evaluated patients …
Effect of bone loss on the fracture resistance of narrow dental implants after implantoplasty. An in vitro study
2021
Background Implantoplasty (IP) involves polishing of the exposed surface of implants affected by peri-implantitis (PI). A study was made to determine whether the degree of bone loss influences the fracture resistance of implants with or without IP. Material and Methods An in vitro study was carried out on 32 narrow (3.5 mm) dental implants with a rough surface and external hexagonal connection. Implantoplasty was performed in half of the implants of the sample. Both the IP and control implants were divided into two subgroups according to the amount of bone loss (3 mm or 7.5 mm). Standardized radiographic assessment of implant width was performed using specific software. The main outcome var…
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…
Methylprednisolone neutralizes the beneficial effects of erythropoietin in experimental spinal cord injury
2005
Inflammation plays a major pathological role in spinal cord injury (SCI). Although antiinflammatory treatment using the glucocorticoid methyprednisolone sodium succinate (MPSS) improved outcomes in several multicenter clinical trials, additional clinical experience suggests that MPSS is only modestly beneficial in SCI and poses a risk for serious complications. Recent work has shown that erythropoietin (EPO) moderates CNS tissue injury, in part by reducing inflammation, limiting neuronal apoptosis, and restoring vascular autoregulation. We determined whether EPO and MPSS act synergistically in SCI. Using a rat model of contusive SCI, we compared the effects of EPO [500-5,000 units/kg of bod…
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…
