Besides respiratory symptoms, coronavirus disease 2019 , like the severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV), has neurological signs. Symptoms like myalgia, headaches, dizziness, anosmia, ageusia and disorder of consciousness confirms that the nervous system is involved in COVID-19 infection. Guillain barre syndrome (GBS) is a neurological disorder that usually follows a viral infection, it is possible that COVID-19 infection and GBS are closely related. In this case report, we try to elucidate the relation between SARS-CoV-2 and GBS.

Pneumonia due to SARS-CoV-2 has caused considerable morbidity and mortalityworldwide particularly amongst those with comorbidities. The most frequent comorbidities are hypertension, diabetes and cardiovascular disease. until now, few associations between obstructive sleep apnea syndrome (OSAS) and COVID-19 have been reported. So, through the column of this article, Given the limited number of clinical cases reported about obstructive sleep apnea and COVID-19, we would like to report a case and share some experiences.

A new family type of coronavirus (SARS-CoV-2) was first seen in Wuhan, China name coronavirus disease 2019 (COVID-19). COVID-19 primarily attacks the respiratory system, but several studies have shown that infection with SARS-COV-2 can cause thrombosis and have therefore considered COVID-19 to be a prothrombotic disease. Behçet's disease (MB) is a systemic vasculitis. Its ethiopathogeny is still poorly understood. Blood vessels of any caliber can be affected. Arterial involvement, such as thrombosis and / or aneurysm, is possible. This article reports the case of SARS-COV-2 infection in a patient with behcet's disease.

Abstract. During the last years, Morocco’s Environmental, Social and Touristic perspectives has improved significantly, but it remains one of the biggest challenges for Mohammedia city. The purpose of this study is to locate an optimal site for the construction of a new Waste Water Treatment Plant (WWTP) in order to help the environment, to select an appropriate site for the construction of a new School that will benefit the social needs of the city and to create a suitable tour plan of touristic sites for tourism. It was carried out by using Geographic Information System (GIS), Remote Sensing (RS), Global Positioning System (GPS) devices, Digital cameras and Multi- criteria Decision Analysis (MCDA).Throughout the process, the used data for both WWTP and School selection include the remote sensing data of multi spectral satellite imageries and the digital elevation model combined with vector data of land use (LU) layers, and for Tour creation the used data include collected photographs and GPS data from the site. According to MCDA, the results presents an optimal site with an area of 48283,02 m2 for a new WWTP, a suitable area with an area of 3200 m² for a new School and a city tour for tourists with a distance of 27 km.
