Awareness of Hail Region Population about Facial Nerve Palsy (Seventh Cranial Nerve Palsy)

引用

Neuroscience & Medicine 2022年第3期13卷 111-119页

作者： Ghorashy Eltayeb Yousif Turki Saud alshammari hamoud Abdelkarim Almarshadi College of Medicine University of Ha’il Ha’il Saudi Arabia Department of Pathology and Microbiology University of Kordofan El-Obeid Sudan

Background: Facial nerve palsy (seventh cranial nerve palsy) is a common neurological problem. The etiology is not fully understood but it is thought to be due to injury or compression throughout the seventh cranial nerve course. The study aimed to evaluate the awareness of the Hail region population about facial nerve palsy, its risk factors, methods of treatment, and prognosis. Methodology: This cross-sectional descriptive study was conducted in the Hail region from March to June 2022. The study involved 224 participants in the age group 18 - 65 years and data was collected through Google self-administered questionnaire. Results: 65.2% of the participants were 18 - 25 years, 20.1% were 26 - 35 years and 14.7 were above 35 years. 91.9% think that exposure to cold air is the leading cause followed by viral infections (30.4%), stroke (27.6%), and genetic factors (13.8%). diabetes (8.5%), evil eye (7.1%), magic (4%), pregnancy (0.4%) and vitamins deficiency (0.4%). 92% of participants think that facial nerve palsy is not contagious and 8% have no clear idea. 89.7% think that facial nerve palsy is curable, 83.9% think that physiotherapy is the treatment of choice, 94.6% agree that early medical assessment is essential for good outcomes and 92.9 believe that avoidance of cold air is the best method of prevention. Conclusion and Recommendations: The majority of participants show poor awareness regarding the etiology and the preferable treatment of facial nerve palsy. Public medical education and further wider studies are highly recommended.

Combinations of metal and lanthanide oxides have been done through casted films for potential medical applications. In this regard, samarium(Ⅲ) oxide/chromium(Ⅲ) oxide/graphene oxide(GO)/polycaprolactone(PCL) based films nano-composites(NCs) were fabricated, pointing their utilization as a biological scaffold for wound dressing purposes. Also, samarium(Ⅲ) oxide and chromium(Ⅲ) oxide have been merged as promising optical constituents due to their unique optical behavior. The structural and compositional examination of the studied NCs was executed by X-ray diffraction(XRD), Raman, and field emission scanning electron microscopy(FESEM). The Sm_(2)O_(3)/Cr_(2)O_(3)/GO/PCL NC exhibits a surface with a lower roughness degree owing to the presence of GO. Cr_(2)O_(3)shows size reduction upon GO insertion to reach 1.2 μm as the average grain size, whilst Sm_(2)O_(3)records an average grain size of less than 1 μm. As well, the polymeric nano-compositions exhibit variation in contact angle values that hit 29.76°± 3.52°for Sm_(2)O_(3)/PCL, and 48.62°± 1.37°for Sm_(2)O_(3)/Cr_(2)O_(3)/GO/PCL as the second lowest contact angle. The optical behavior contributes to absorption edge relocation along the x-axis from 1.7 eV for pure PCL, to 2.65 eV for Sm_(2)O_(3)/Cr_(2)O_(3)/GO/PCL. Regarding biological responses, the cell exposed to 2.5 μg/m L of Sm_(2)O_(3)/Cr_(2)O_(3)/GO/PCL shows cell viability of 119.31%, while 5 μg/m L hits 99.6%. Additionally, the resulting cell attachment micrographs show layers of fibroblast tissue, besides the proliferation and growth of cultivated cells. Thus, the Sm_(2)O_(3)/Cr_(2)O_(3)/GO/PCL scaffold provides 3D proliferation of fibroblast cells endorsing the wound healing process.
