Introduction: Neuroendocrine carcinoma is an aggressive neoplasm with a high recurrence potential. Its location in the Sino nasal tract is considered a rare disease. CT and MR imaging features of these tumors are nonspecific. Paranasal sinus neuroendocrine carcinomas showed expansion and destruction of the sinus. Endoscopic examination is complementary to imaging and mandatory in order to reveal early stage tumour and its extension. Treatment recommendations for this entity vary considerably due largely to a lack of consensus and variable pathological classification.

A cross-sectional survey design utilizing an ex-post factor design was adopted to validate the Gaming Addiction Scale (GAS) using Nigerian secondary school adolescents. A purposive sampling technique was used to select the 338 (mean age and SD13.60 ±1.867) participants made up of 149 males and 189 females from several randomly selected secondary schools in a Local Government Area of Edo State, Nigeria.

This paper examines CP levels and performance outcomes of four community-based tourism projects in the Coastal region of Kenya that has been witnessing a steadily increasing number of tourists. The attraction of visitors to this region has been due to its relatively well developed first class establishment that are juxtaposed in close proximity to pristine glistering tropical sandy beaches and world renowned wildlife attractions. The region is thus a major popular destination for international visitors, especially Europeans, North Americans, and in the recent past the Oriental Asians.

Background: An outbreak of novel coronavirus disease (COVID-19) in China has influenced every aspect of life. Healthcare professionals, especially dentists, are exposed to a higher risk of getting infected due to close contact with infected patients. Despite having a high standard of knowledge and practice, dental practitioners around the globe are in a state of anxiety and fear while working in their respective fields due to the COVID-19 pandemic impact on humanity.

Cygb is an O2 carrier protein expressed by fibroblasts. In fibrosis, hypoxia occurs as characterized by stabilization of hypoxia-inducible factor-1α (HIF-1α), which later form the HIF-1, a transcription factor for the expression of adaptation proteins (including Cygb). The purpose of this study was to obtain information about Cygb role in fibrosis hypoxia using keloid tissue as a model. This was an observational descriptive study using keloid tissue samples, and the preputium as control. Measurement of Cygb and HIF-1α mRNA expression by real-time RT–PCR.

During the last years there has been a growing interest to care quality in developed countries and certain developing countries as well since patients have become active partners in medical care nowadays. The purpose of this work is to assess the satisfaction of the hospitalized patients at eleven (11) MCO departments of the University Hospital Center of ORAN (UHC). Materials and Methods: We have carried out a prospective study during 15 days of two samples (groups) of eleven (11) hospital depts. Picked at random during the periods of October-November 2017 and December-January 2018.

Sheehan's syndrome (SS) or postpartum hypopituitarism is a rare condition due to the necrosis of the pituitary gland. More often, this is caused by acute hypotension or hypovolemia related to excessive haemorrhage with or after delivery. The following article sheds light on the evolution of pituitary changes and also tackles the differential diagnosis involving Sheehan syndrome by means of MR imaging in a female patient after caesarean delivery.

Background: In this era of digital innovation, mobile health (mHealth) has emerged as a novel concept in the health care industry. Mobile Health is defined as using mobile communications for health interventions and information, and involves the use of portable devices that are capable of creating, storing, retrieving, and transmitting data to improve the safety, quality of care, and health of end users. However, the efficacy of these apps in improving healthcare delivery to Muslim pilgrims arriving in Saudi Arabia each year is yet to be determined.

Background: The JAK2 V617F mutation has been noted in a majority of cases of polycythemia Vera, essential thrombocythemia, and primary myelofibrosis patients but occurs less frequently in myelodysplastic syndrome (MDS) about 5% of the cases; In Morocco, the Incidence of MDS will increase significantly in our country, MDS will be the disease of national public health. The aim of the current study was to determine prevalence of JAK2V617F mutation in Moroccan patients with MDS, and to compare characteristics of JAK2 mutation group to JAK2 wild type group.

Despite having advances in treatment, prognosis for patients with oral cancer remains poor. Early diagnosis and treatment remains key to improved patient survival. Traditional methods of screening oral malignancies involve a conventional oral examination with digital palpation. A number of optical aids have been developed to assist the clinician to detect abnormalities and in early diagnosis of oral cancer.
