Histo-Epidemiological Profile of Endometrial Cancer in the Oran Region

Objective: The aim of the present study is to describe the epidemiological, histopathological and therapeutic profile of endometrial cancers in the region of Oran. Methods: We conducted a retrospective study by exploring the medical files of 25 female patients diagnosed of endometrial cancer and treated at the level of the EHU November 1, 1954’s medical oncology department in Oran during the period from January 2015 to December 2019. For data collection, we used a structured exploitation sheet to obtain necessary information. Variables were analyzed using SPSS Software Version 20.0. Results: The median age of patients was 59 years with extremes ranging from 42 to 83 years. More than 56% of our patients were over 50 years old, 40% of the patients were nulliparous and 80% postmenopausal. The average age of menarche was 14.09 ± 1.44 years with extremes ranging from 12 to 17 years. The indication for anatomopathological examination was dominated by metrorrhagia (80%). Histopathologically, endometrioid adenocarcinoma was the most common at 75% of cases. We also note that 62.5% were classified in stage I and 37.5% in stage II. Myometrium infiltration was observed in 66.67% of cases. The basic treatment for endometrial cancer remains surgical. Conclusion: At the end of this work, we concluded that this pathology remains essentially that of postmenopausal women. Endometrioid adenocarcinoma was the most common histologic type. This study also revealed many risk factors for endometrial cancer, such as advanced age, hypertension and nulliparity. Keywords: Cancer, Endometrium, Epidemiology, Anathomopathology, Risk factors

Etat des connaissances et conservation de flore endemique dans la region d’Oran (Algerie occidentale)

ResumeCette étude est une première exploration régionale visant la recherche des plantes endémiques de la région d›Oran en vue d›une éventuelle évaluation de leur état de conservation. Les recherches se sont basées essentiellement sur les 124 relevés phytoecologiques réalisés à travers les secteurs O1 et O2 ainsi que certains sorties ciblant les stations de présence des espèces endémiques signalées pour la région d›Oran dans la littérature. Ces recherches de terrain ont conduit à l›identification de 17 taxons endémiques dont certains sont très rares comme Brassic aspinescens et Helianthemum maritimum. D’autres espèces ayant été ciblées par les recherches n’ont pas été retrouvées ce qui renforce l’hypothèse de disparition de certaines d’entre elles. En plus de cette première liste des endémiques réellement observés dans la région depuis l’indépendance du pays, les données sur leurs aspects chorologiques, écologiques et biogéographiques sont exposées et discutés. Mots clés: Endémique, flore, chorologie, conservation, inventaire, Oran, rare. AbstractThis study is a first regional exploration for plants research of the Oran region for a possible evaluation for their conditions of conservation. The research were basically based on 124 phytoecological records carried out across the sectors O1 and O2 as well as some data targeting endemic species presence stations reported for the region of Oran in the literature. This field searches led to the identification of 17 endemic taxa some of which are very rare like Brassica spinescens and Helianthemum maritimum. Other targeted species were not found, which reinforces the hypothesis of the disappearance of some of them. In addition to this first list of endemics actually observed in the region since the independence of the country, the data on their chorological, ecological and phytobiogeographical aspects are exposed and discussed. Key words: Endemics, flora, chorology, conservation, inventory, Oran, rare.

Climate change and water resources management of Oran region

Our work aims to contribute to the literature on the prospective study of the water balance in the Oran region, a major southern Mediterranean metropolis, by considering the socioeconomic dimension of this region and the dynamic of its climate change through 2011–2030. These two dimensions are important for the analysis of future changes in water stress in the region because they affect both the demand and the supply of the water resources. Unlike other studies, our methodological approach is based on an explicit modeling of the socioeconomic evolution in the region as well as of the dynamic of climate change. For this, we used a time-series modeling framework to predict the effects of change in climate. In addition to the assessment of the effects of the socioeconomic and climate changes on the water balance of the region. Our results, based on simulations using the Water Evaluation and Planning (WEAP) software, show that the current decoupling between the drinking sector from that of irrigation in the Oran region is not sustainable. Climate change will exacerbate this vulnerability. Only by integrating these two sectors, through a reuse of wastewater, can we consider the irrigation issue from a perspective of long-term sustainability in the region.
