Background: Lower-extremity fractures (LEFs) account for >30% of all skeletal injuries, contributing to the global health and economic burden. Fracture epidemiology in the Middle East and North Africa (MENA) region has been studied little. Health factors and disease epidemiology differ greatly among populations in MENA despite cultural, political, and economic similarities among the region’s countries. This study examined the epidemiology of LEFs and the need for rehabilitation in MENA from 1990 to 2019. Methods: We examined the epidemiology of fractures of the pelvis, hip, femur, patella, tibia, fibula, ankle, and foot bones using Global Burden of Disease (GBD) data. Fracture incidence, counts, and rates were measured for males and females across age groups in the 21 MENA countries as identified by the GBD data set. Associations between years of healthy life lost due to disability (YLD) resulting from fracture and the Socio-demographic Index (SDI) were analyzed. Results: In contrast to the global trend, the age-standardized incidence rate (ASIR) of LEFs in the MENA region increased by 4.57% from 1990 to 2019. In 2019, the highest ASIR among fractures was attributed to fractures of the patella, fibula, tibia, or ankle (434.36 per 100,000), most frequently occurring among those 20 to 24 years of age. In 2019, the highest ASIR of all fractures was noted in Saudi Arabia (2,010.56 per 100,000) and the lowest, in Sudan (523.29 per 100,000). The greatest increases from 1990 to 2019 in the ASIR of LEFs were noted in Yemen (132.39%), Syria (107.27%), and Afghanistan (94.47%), while the largest decreases were found in Kuwait (−62.72%), Sudan (−48.72%), and Iran (−45.37%). In 2019, the YLD rate of LEFs had increased to 277.65 per 100,000, up from 235.55 per 100,000 in 1990. Conclusions: Between 1990 and 2019, LEFs increased in the MENA region. Violence, war, and road traffic accidents increased, leading to a high rate of fractures, especially among youth. Low bone-mineral density related to vitamin D deficiency has also been reported as a risk factor for fracture in the region. Regional health authorities should be informed of fracture patterns by this study. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

We aimed to assess the Iranian people’s attitude and confidence in the COVID-19 vaccine, their concerns about the safety of vaccines, and their reasons for accepting or rejecting the COVID-19 vaccine. We conducted a web-based cross-sectional study with a mixed qualitative–quantitative approach from December 2020 to February 2021. Our questionnaire consisted of a COVID-19 vaccine attitude questionnaire, a COVID-19 vaccine confidence inventory, a modified vaccine safety scale, and questions about participants’ decision to accept or refuse the COVID-19 vaccine, and their explanations for their decisions. The research included 1928 people with an average age of 34.88 years with 1236 (64.1%) being female. A total of 1330 participants desired to have the COVID-19 vaccine (69%). Female gender, lower educational levels, following COVID-19 news through sources other than websites and social media, not following COVID-19 news, and loss of a first-degree relative due to COVID-19 were all associated with a more negative attitude toward the COVID-19 vaccine (p < 0.01). To conclude, the acceptance rate of the COVID-19 vaccine among Iranians is comparable to the international average; however, it is still unfavorable. There are serious challenges to the vaccination program in Iran, such as older adults’ lower intention to undergo the COVID-19 vaccine and misinformation.

Background: Upper-extremity fractures (UEFs) account for a large proportion of bone fractures and are costly to both health and the economy. The fracture burden in the Middle East and North Africa (MENA) is influenced by the region’s diverse cultural, economic, and political status. This study examined UEF epidemiology and causes across the MENA region and within the 21 MENA countries as categorized by the Global Burden of Disease (GBD) data set. Methods: On the basis of GBD data, this study evaluated the epidemiology of UEFs from 1990 to 2019. The causes of injuries, incidence, number of years of healthy life lost due to disability (YLD), and their association with the Socio-demographic Index (SDI) were obtained and calculated for males and females in all age groups. Results: From 1990 to 2019, the age-standardized incidence rate (ASIR) of UEFs in the MENA region increased by 2.33%, to 1,086.39 per 100,000 people, and the YLD rate increased 15.69%, to 9.17 per 100,000, opposing the global decreasing trends. Fractures of the radius and/or ulna had the highest ASIR (505.32 per 100,000) of all UEF types in 2019. The clavicle, scapula, and humerus had the highest increasing trend among the fracture sites. In 2019, Saudi Arabia had the highest ASIR of UEFs (2,296.93 per 100,000). Afghanistan had the highest age-standardized YLD rate due to UEFs (19.6 per 100,000) in 2019, with Syria (153.32%) and Iran (37.04%) experiencing the greatest increase and decrease, respectively, from 1990 to 2019. Falling was the leading cause of UEFs, accounting for 45.05% of incidence and 41.19% of YLD overall. Conclusions: Contrary to global trends, UEFs increased in the MENA region during the study period. Countries with higher fracture incidence and YLD should consider preventive and rehabilitation strategies.

Primary intradural extramedullary Ewing sarcoma (IEES) is the rarest type of Ewing sarcoma. Extreme caution is required for the diagnosis of IEES because benign intradural spinal tumors can be mistaken for IEES in the early stages of imaging and clinical evaluation. IEES tumors have no standardized treatment guidelines because of the lack of research on the therapeutic aspects of these tumors. Herein, we present a case of primary IEES in a male adolescent with a fast progression of the disease. Diagnosis of IEES was suspected with imaging (computed tomography scan and lumbosacral magnetic resonance imaging) and was confirmed with histology and immunohistochemistry (positive reactivity for CD99 and FLI1). He was successfully treated with surgical intervention with no radiotherapy or chemotherapy. Imaging studies are helpful in making the initial diagnosis of intradural extramedullary Ewing sarcoma. Surgery is considered to be a successful method of treatment for this condition.
