Case Report of Malignant Endometrial Polyps

The aims of this retrospective review were to determine the frequency of malignant endometrial polyps diagnosed with ambulatory hysteroscopy in the Obstetrics/Gynaecology Department of HDE, Lisbon, between January 2001 and December 2005 and to characterize these cases according to risk factors, sonographic and endoscopic findings tumoral histology, and tumor stage.We found seven cases of malignant endometrial polyps in a total of 1333 polyps initially diagnosed: an incidence rate of 0. 53%. These seven patients had a mean age of 68 years (55–82 years), and all were postmenopausal, with five having one risk factor each for endometrial cancer. Metrorrhagia was present in six of the seven patients(85.7%). Ultrasonography was abnormal in all seven patients, with a mean endometrial thickness of 26 mm(range: 12–44 mm). The hysteroscopy images suggested malignancy in all cases. All except one patient had a single polyp. The polyps had volumes between 1.5 and 3 cm; two were removed completely and five were biopsed. The histological subtype was: mixed endometrioid/serous papillary or clear cell (2), adenocarcinoma with squamous differentiation (2), carcinosarcoma (2), and clear cell carcinoma (1). Malignancy inside polyps is rare, but diagnostic hysteroscopy with visual guided biopsies can identify these cases in the earlier stages. The risk factors are not different from those of other endometrial carcinomas, but the histological subtype seems to point to more aggressive cancers

Students’ perceptions of assessment: a comparative analysis between Portugal and Sweden

This paper aims at investigating students’ perceptions about assessment, especially the ways in which it is put into practice. Data were collected through questionnaires in different programmes in Portugal and Sweden. In total, 173 students from Portugal and 72 from Sweden participated in the study. Findings showed that students had similar ideas about assessment, such as verification of knowledge and learning, tests and grades. Their experiences of assessment methods used varied in the two countries, which can partly be explained by differences in national education systems. A learner-oriented perspective is prominent in the use of assessment methods, but at the same time student influence on assessment is perceived as low in both countries. Implications of the findings are analysed, namely issues regarding a learner-oriented perspective and the effectiveness, influence, trust, times and methods of assessment.Understanding the assessment process, including the concepts and methods used, is essential to educational practice. In recent years new trends on assessment have emerged from an integrated perspective of the teaching, learning and assessment process (Rust 2007). In contrast to summative assessment, which can be perceived as mainly using assessment to certify student achievement (Boud and Falchikov 2006; Hernández 2012), formative assessment supports and monitors the students’ learning, providing continuous feedback during the process (Yorke 2003; Weurlander et al. 2012), and informing them about their performance (Boud 1990; Brown and Knight 1994; Brew et al. 2009). These trends have introduced new methods of assessment (Brew et al. 2009) and more participatory practices, such as self, peer, and co-assessment (Dochy, Segers and Sluijsmans 1999).National Funds through the FCT (Foundation for Science and Technology) and co-financed by European Regional Development Funds (FEDER) through the Competitiveness and Internationalization Operational Program (POCI) through CIEC (Research Centre on Child Studies, of the University of Minho) with the reference POCI-01-0145-FEDER-007562Strategic Project UID/CED/00317/2013CIEC – Research Centre on Child Studies, IE, UMinho (FCT R&D unit 317), Portugalinfo:eu-repo/semantics/publishedVersio

Myomectomy in Early Pregnancy - A Case Report

Uterine leiomyomas are by far the most common benign tumours of the female genital tract. The true incidence of leiomyomas during pregnancy is, however, unknown. Although leiomyomas usually remain asymptomatic during pregnancy, they may complicate its course. The management of leiomyoma during pregnancy is medical, but, in rare circumstances, surgical intervention and myomectomy may be required. A case of myomectomy in early pregnancy is described

The gathering firestorm in southern Amazonia.

Wildfires, exacerbated by extreme weather events and land use, threaten to change the Amazon from a net carbon sink to a net carbon source. Here, we develop and apply a coupled ecosystem-fire model to quantify how greenhouse gas-driven drying and warming would affect wildfires and associated CO2 emissions in the southern Brazilian Amazon. Regional climate projections suggest that Amazon fire regimes will intensify under both low- and high-emission scenarios. Our results indicate that projected climatic changes will double the area burned by wildfires, affecting up to 16% of the region's forests by 2050. Although these fires could emit as much as 17.0 Pg of CO2 equivalent to the atmosphere, avoiding new deforestation could cut total net fire emissions in half and help prevent fires from escaping into protected areas and indigenous lands. Aggressive efforts to eliminate ignition sources and suppress wildfires will be critical to conserve southern Amazon forests

Efeitos salinos no crescimento e desenvolvimento do arroz: alterações fisiológicas.

Com o objetivo de avaliar os efeitos do NaCl sobre o desenvolvimento vegetativo de plantas de arroz (Oryza sativa L.) (cultivar IAC 25, um experimento foi conduzido em casa de vegetação no Centro de Ciências Agrárias da Universidade Federal do Ceará, em Fortaleza, CE. Sob os potenciais osmóticos de 0,0, -0,4, -0,8 e -1,2 MPa de NaCl, foram avaliados o peso da matéria seca da parte aérea e da raiz, o peso da matéria seca total, a relação raiz/parte aérea, o volume e o comprimento das raízes, o número de perfilhos por planta e transpiração/ planta/dia. O aumento da concentração salina provocou reduções significativas no peso da matéria seca da parte aérea. O comprimento e o volume das raízes foram reduzidos significativamente com o aumento do teor de NaCl na solução nutritiva. O número de perfilhos/planta, mesmo sendo uma característica genética, sofreu redução significativa com o aumento da concentração de NaCl. O aumento do nível salino reduziu o volume de água transpirado, principalmente nos tratamentos com potenciais osmóticos de -0,4 MPa. A salinização do meio de cultivo provocou envelhecimento precoce nas plantas de arroz
