Repositório Comum (40.785 recursos)

É um repositório para instituições de ensino e investigação produtoras de literatura científica cuja dimensão ainda não justifica a criação de um repositório próprio. Permite integrar instituições, grupos ou indivíduos na infra-estrutura do projecto, nomeadamente através das pesquisas do Portal RCAAP e da B-On.

  1. Stevens-Johnson syndrome/toxic epidermal necrolysis and erythema multiforme drug-related hospitalisations in a national administrative database

    Sousa-Pinto, B; Araújo, L; Freitas, A; Correia, O; Delgado, L
    BACKGROUND: Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) and erythema multiforme (EM) are immunologically-mediated dermatological disorders commonly triggered by drug exposure and/or other external agents. We aimed to characterise SJS/TEN- and EM-drug-related hospitalisations in a nationwide administrative database, focusing on demographic and clinical characteristics, and in the most frequently implicated drug classes. METHODS: We analysed all drug-related hospitalisations with associated diagnosis of SJS/TEN or EM in Portuguese hospitals between 2009 and 2014. We compared gender, age, comorbidities, length of stay, and in-hospital mortality and estimated the number of episodes per million packages sold of drug classes. Predictors of in-hospital mortality were investigated in both conditions...

  2. Nail psoriasis: clinical features, pathogenesis, differential diagnoses, and management

    Haneke, E
    Psoriasis is the skin disease that most frequently affects the nails. Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia. The more extensive the involvement, the more severe is the nail destruction. Pustular psoriasis may be...

  3. 3D echoendoscopy and miniprobes for rectal cancer staging

    Castro-Poças, F; Dinis-Ribeiro, M; Rocha, A; Araújo, T; Pedroto, I
    BACKGROUND: Rectal cancer staging using rigid probes or echoendoscopes has some limitations. The aim of the study was to compare rectal cancer preoperative staging using conventional endoluminal ultrasonography with three-dimensional endoscopic ultrasonography and miniprobes. MATERIALS AND METHODS: Sixty patients were included and evaluated with: a) a conventional echoendoscope (7.5 and 12 MHz); b) miniprobes (12 MHz); and c) the Easy 3D Freescan software for three-dimensional endoscopic ultrasonography. The reference or gold standard was conventional endoluminal ultrasonography in all cases and pathological assessment for those without preoperative therapy. The differences in T and N staging accuracy in both longitudinal and circumferential extension were evaluated. RESULTS: With...

  5. Neuropathic pain after breast cancer treatment and its impact on sleep quality one year after cancer diagnosis

    Fontes, F; Gonçalves, M; Pereira, S; Lunet, N
    OBJECTIVES: Data regarding the impact of breast cancer treatment-related neuropathic pain (NP) on sleep quality are scarce. Therefore, we aimed to assess the impact of breast cancer treatment-related NP on patients' sleep quality, during the first year after cancer diagnosis. MATERIALS AND METHODS: A total of 501 breast cancer patients were followed prospectively. Incident NP was identified through systematic evaluations after treatments and one year after enrolment. NP severity was quantified using the Brief Pain Inventory severity subscale and sleep quality was evaluated through the Pittsburgh Sleep Quality Index (PSQI), at baseline and after one year. Adjusted regression coefficients (β) and 95% confidence...

  8. The Portuguese long version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II) - a validation study

    Rosário, S; Azevedo, LF; Fonseca, JA; Nienhaus, A; Nübling, M; da Costa, JT
    BACKGROUND: Psychosocial risks are now widely recognised as one of the biggest challenges for occupational safety and health (OSH) and a major public health concern. The aim of this paper is to investigate the Portuguese long version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II), in order to analyse the psychometric properties of the instrument and to validate it. METHODS: The Portuguese COPSOQ II was issued to a total of 745 Portuguese employees from both private and public organisations across several economic sectors at a baseline and then 2 weeks later. Methodological quality appraisal was based on COnsensus-based Standards for the selection of...

  9. Follicular Fluid redox involvement for ovarian follicle growth

    Freitas, C; Neto, AC; Matos, L; Silva, E; Ribeiro, Â; Silva-Carvalho, JL; Almeida, H
    As the human ovarian follicle enlarges in the course of a regular cycle or following controlled ovarian stimulation, the changes in its structure reveal the oocyte environment composed of cumulus oophorus cells and the follicular fluid (FF).In contrast to the dynamic nature of cells, the fluid compartment appears as a reservoir rich in biomolecules. In some aspects, it is similar to the plasma, but it also exhibits differences that likely relate to its specific localization around the oocyte. The chemical composition indicates that the follicular fluid is able to detect and buffer excessive amounts of reactive oxygen species, employing a...

  10. International core curriculum for capsule endoscopy training courses

    Fernandez-Urien, I; Panter, S; Carretero, C; Davison, C; Dray, X; Fedorov, E; Makins, R; Mascarenhas, M; McAlindon, M; McNamara, D; Palmer, H; Rey, JF; Saurin, JC; Seitz, U; Spada, C; Toth, E; Wiedbrauck, F; Keuchel, M
    Capsule endoscopy (CE) has become a first-line noninvasive tool for visualisation of the small bowel (SB) and is being increasingly used for investigation of the colon. The European Society of Gastrointestinal Endoscopy (ESGE) guidelines have specified requirements for the clinical applications of CE. However, there are no standardized recommendations yet for CE training courses in Europe. The following suggestions in this curriculum are based on the experience of European CE training courses directors. It is suggested that 12 hours be dedicated for either a small bowel capsule endoscopy (SBCE) or a colon capsule endoscopy (CCE) course with 4 hours for...

  11. Titration with automatic continuous positive airway pressure in obstructive sleep apnea

    Dias, C; Sousa, L; Batata, L; Reis, R; Teixeira, F; Moita, J; Moutinho Dos Santos, J
    Background and objective Autotitrating positive airway pressure (APAP) is an accepted titration method to determine the optimal positive airway pressure (PAP), for the treatment of obstructive sleep apnea (OSA). The required duration of APAP monitoring to determine a fixed continuous positive airway pressure level still remains to be established. We aimed to evaluate the variation in PAP level, delivered by APAP devices, at different periods of treatment, to determine the APAP treatment duration required to reach an effective and stable PAP level. Methods A cross-sectional study of 62 patients newly diagnosed with OSA were evaluated after 3 months of APAP therapy. APAP data...
