Rare cause of fever in a patient with ulcerative colitis

Environmental factors: a systematic review of instruments and content analysis ...

Purpose: This study aims to describe and compare the content of instruments that assess environmental factors (EF) using the International Classification of Functioning, Disability and Health (ICF). Relevance: Assessing the impact of EF on patients' functioning is an important part of the rehabilitation process. Physiotherapists need to know which instruments assess EF, which EF these instruments assess and whi...

Mucormicose Naso-Sinusal - Casos Clínicos e Revisão da Literatura

A mucormicose e uma infecção fúngica potencialmente grave,causada por fungo saprófita. Pode tornar-se patogénico, em condições específicas, com evolução frequentemente fatal, particularmente em indivíduos imunocomprometidos. A doença inicia-se com a inalação do fungo para os seios perinasais. 0 fungo pode invadir o palato, os seios perinasais, o seio cavernoso, as órbitas e cavidade craniana. A chave para uma t...

External validation of a classification for methylene blue magnification chromo...

BACKGROUND: Conventional endoscopy has low sensitivity, specificity, and interobserver agreement for the diagnosis of gastric atrophy, intestinal metaplasia, and dysplasia. Magnification chromoendoscopy (ME) may optimize the evaluation of premalignant gastric lesions. OBJECTIVE AND DESIGN: As part of a multicenter trial, we aimed at validating a previously proposed classification for gastric methylene blue ME a...

Host- and microbe-related risk factors for and pathophysiology of fatal Rickett...

BACKGROUND: The pathophysiologic mechanisms that determine the severity of Mediterranean spotted fever (MSF) and the host-related and microbe-related risk factors for a fatal outcome are incompletely understood. METHODS: This prospective study used univariate and multivariate analyses to determine the risk factors for a fatal outcome for 140 patients with Rickettsia conorii infection admitted to 13 Portuguese h...

Study of the ferrofluid drying process for morphological and nanostructutal cha...

A drying method suitable for the study of the morphological and structural properties of colloidal magnetic systems, including a contrast agent used in Magnetic Resonance Imaging (MRI) is described. We tested three alternative ferrofluid drying methods: drying at 70 70ºCC in nitrogen atmosphere; drying in air at 70 70ºCC; and drying by liophylization using an MRI marker in the form of a colloidal suspension (En...

PACEM: a new concept for high avalanche-ion blocking

We present the Photon-Assisted Cascaded Electron Multiplier (PACEM) as a potential alternative for ion back-flow suppression in gaseous cascade electron multipliers. Using a Micro Hole and Strip Plate-Gas Electron Multiplier (MHSP-GEM) configuration, the number of ions flowing back to the scintillation region is about 1.5 ions per primary electron at an optical gain of 6.5 and a drift field of 0.1 kV/cm, and ab...

Intralesional expression of mRNA of interferon- gamma, tumor necrosis factor- a...

BACKGROUND: The mechanisms of immunity to Rickettsia conorii that have been elucidated in mouse models have not been evaluated in human tissues. METHODS: In this study, quantitative real-time polymerase chain reaction was used to determine the levels of expression of inflammatory and immune mediators in skin-biopsy samples collected from 23 untreated patients with Mediterranean spotted fever (MSF). RESULTS: In ...
