Oral and maxillofacial lesions in older individuals and associated factors: A retrospective analysis of cases retrieved in two different services.
2019
Background Studies on the oral and maxillofacial lesions (OMLs) in older people usually assess data of laboratory services and data from oral medicine clinic have been poorly described. The aim of this study was to describe and to compare OMLs in older individuals considering two data sources, besides to assess associated factors with the three most frequent lesions. Material and Methods A retrospective study was conducted with individuals aged 60 years or older. Data of individuals and lesions reported in both services were collected. Univariate analysis was used to test the association between the occurrence of the lesion and the independent variables. The level of significance was set at…
The Assessment of Diffuse Disease
2016
A significant drop in pressure can be observed also in the absence of focal lesions. The presence of hemodynamically relevant, diffuse atherosclerosis is actually very frequent and it may affect as many as 50 % of those patients who have at least one focal lesion in another vessel. FFR in this setting may clarify the possible reason for residual angina after successful stenting.
Vertigo, Masseter Paresis or Masseter Reflex Abnormality, and Impaired Caloric Response
1993
Symptoms and signs of acute peripheral-type vestibular abnormalities occasionally occur in patients with multiple sclerosis and brain-stem ischemia. Such patients may show reduced excitability of the lateral semicircular canal. From this observation, the question arises as to the location of the causative lesion.
Vaskulärer Schwindel
2002
Ischemia,hemorrhages, and other vascular disorders can result in various central or peripheral vestibular syndromes with vertigo, oculomotor/balance disturbances, and nausea. The vascular vertigo syndromes listed in Table 1 can however be brought about by other causes such as demyelitizing focuses in multiple sclerosis or space-occupying lesions, so that not only localization of the damaged structure but also the various etiologies are decisive for the choice of therapy. Occasionally, combined functional disturbances of the peripheral and central vestibular system appear, such as an infarction of the inferior anterior cerebellar artery, which supplies the labyrinth and parts of the brainste…
Posterior insular cortex - a site of vestibular-somatosensory interaction?
2013
Background In previous imaging studies the insular cortex (IC) has been identified as an essential part of the processing of a wide spectrum of perception and sensorimotor integration. Yet, there are no systematic lesion studies in a sufficient number of patients examining whether processing of vestibular and the interaction of somatosensory and vestibular signals take place in the IC. Methods We investigated acute stroke patients with lesions affecting the IC in order to fill this gap. In detail, we explored signs of a vestibular tone imbalance such as the deviation of the subjective visual vertical (SVV). We applied voxel-lesion behaviour mapping analysis in 27 patients with acute unilate…
Virtual bronchoscopy in patients with central endobronchial stenosing lesions. Technique optimisation with single slice spiral CT.
2004
PURPOSE: To describe an original protocol for single slice spiral Computed Tomography (CT) virtual bronchoscopy in the evaluation of patients with central airway stenoses and compare the results with fibreoptic bronchoscopy. MATERIALS AND METHODS: Ten patients (4 female and 6 male; age range 22-60 years; mean age 44 years) with endobronchial disease diagnosed by fibreoptic bronchoscopy (8 malignant tumours, 1 benign tumour and 1 fibroid stenosis) underwent virtual bronchoscopy with single slice spiral CT. A panoramic spiral CT scan of the whole chest was first obtained. Once the area of interest had been identified, a new contrast enhanced scan was performed, from bottom to top, with the fo…
Weakness and focal sensory deficits in the postictal state.
2010
Postictal motor deficits may occur in patients following partial and generalized tonic-clonic seizures. Frequency is unclear, epidemiology being hampered by heterogeneous populations and variable methods of detection. Postictal paresis may affect any body part, may be bilateral, and may occur more frequently in seizures involving the sensorimotor cortex. Duration varies depending on the precise mode of testing from a few minutes to 36 hours. Sensory deficits following seizures have been rarely reported but may be missed if not specifically tested for. The lateralizing value of postical paresis is high (>90%), pointing to a seizure origin in the opposite frontal lobe. Postictal paresis often…
Comparación de las lesiones por accidente de trabajo en trabajadores extranjeros y españoles por actividad económica y comunidad autónoma (España, 20…
2008
Fundamento: Aunque el colectivo de personas inmigrantes en nuestro país se ha incrementado notablemente en los últimos años, poco se sabe de sus condiciones de trabajo y de los efectos de éstas en términos de lesiones por accidentes de trabajo. El objetivo de este trabajo fue comparar, para el año 2005, la incidencia de lesiones mortales y no mortales de las personas extranjeras con las de las españolas por actividad económica y comunidad autónoma. Métodos: Los datos de lesiones por accidentes de trabajo (LAT) procedieron del Registro de Accidentes de Trabajo del Ministerio de Trabajo y Asuntos Sociales y los denominadores se obtuvieron de las estadísticas disponibles sobre afiliación a la …
A novel homologous model for noninvasive monitoring of endometriosis progression.
2017
To date, several groups have generated homologous models of endometriosis through the implantation of endometrial tissue fluorescently labeled by green fluorescent protein (GFP) or tissue from luciferase-expressing transgenic mice into recipient animals, enabling noninvasive monitoring of lesion signal. These models present an advantage over endpoint models, but some limitations persist; use of transgenic mice is laborious and expensive, and GFP presents poor tissue penetration due to the relatively short emission wavelength. For this reason, a homologous mouse model of endometriosis that allows in vivo monitoring of generated lesions over time and mimics human lesions in recipient mice wou…
