Background Several osteotomies are required for orthognathic surgery to reposition the jaws correctly. This study aimed to evaluate whether Kinesiotaping can reduce swelling, pain, and trismus following orthognathic surgery of the facial skull. Materials and methods The present study consists of two phases. In the split-mouth phase, 16 skeletal class III patients underwent Bimax Orthognathic surgery, and Kinesiological tape (KT) was applied on one half of the face. In the prospective case–control phase, 30 patients were divided into two groups. Kinesio tape was applied on both sides of the face of the Kinesio group, and pressure dressing and ice therapy were used for the second group. The tape was parallel to the lower border of the mandible along its entire length, tangent to the labial commissure area on the studied side. The tape was placed in place for 5 days. Edema was evaluated by measuring the distance from the menton to the lower edge of the tragus. The maximum mouth-opening trismus was evaluated, and the VAS index was used to evaluate pain. Results There was evidence of swelling reduction after KT; within the same study, differences between the left and right sides as well as for the same side were statistically significant (p < 0.001). As a result of tapping lymphatic Kinesio tape on the affected area, tension was reduced, and lymphatic circulation was restored. Blood and lymph microcirculation was improved, enabling the body to heal itself. Conclusion Kinesio tape reduced swelling after orthognathic surgery in a positive way. As a simple, non-traumatic, economical method, Kinesio taping seems promising.
Background and aim: A wide range of therapeutic properties, including anti-cancer properties, are attributed to propolis, a resinous product obtained from several plants that possess a variety of medicinal properties. A study on honeybee-produced propolis showed that in mice, it showed a significant reduction in the progression of squamous cell carcinoma in the head and neck, but in humans, its role in HNSCC remains unclear. Method and materials: Propolis was sampled from two types of Iranian. Extraction was done using ethanolic extracts of propolis. The cll viability was evaluated by MTT assay. Cancer cell lines were assessed for gene expression, such as mmp-2, mmp-9, bax, and bcl-2. Results: Increased sample concentrations reduced cell viability but did not cause significant cytotoxicity. A RT-PCR indicated that the Khalkhal sample produced more effects among the two samples, and the level of bax mRNA gene expression in the Khalkhal sample was increased. With an increasing concentration of Khalkhal samples, the expression increased. Increasing Khalkhal sample concentration also reduced mRNA levels of bcl-2, mmp-2, and mmp-9. Conclusion: Khalkhal’s propolis can be considered a suitable sample for the study of antiapoptotic and proapoptotic gene expression. Additionally, it can be used as a potential candidate for inhibiting the proliferation and spread of oral cancer cells.
BACKGROUND: Renal cell carcinoma is one of the most common tumors of the kidney. Glucose transporters, transport glucose, and increased expression of these transporters have been reported in various tumor types. Glucose transporter 1 (GLUT1), the best-known glucose transporter, has an important role at several stages in cancer progression. The overexpression of GLUT1 in the tumor cells indicates an increased proliferation and invasive behavior of the tumor. AIM: This study aims to investigate the expression of GLUT1 in renal cell carcinoma and its subtypes. METHODS: This study is a descriptive cross-sectional study that was performed on patients with renal cell carcinoma. Seventy reports of formalin fixed; paraffin-embedded blocks of renal cell carcinoma were selected from pathology archives. The samples included: clear cell type renal cell carcinoma, RCC clear cell type with sarcomatoid feature, papillary renal cell carcinoma, and chromophobe renal cell carcinoma. RESULTS: In this study, 50 male and 20 female samples (71.4% and 28.6%) with the mean age of 57.9 ± 13.1 years were studied. Forty-three samples (61.4%) were positive for GLUT1 and 27 (38.9%) were negative for it. For the GLUT1 expression being positive or negative between the two groups, was not significantly affected by the age, sex, and the grade of the tumor, </AQ17>while the difference between the two groups was statistically significant in terms of stage and type of tumor (p < 0/001, p = 0.039). CONCLUSION: Renal cell carcinoma of ccRCC type is associated with increased GLUT1 expression. Therefore, the GLUT1 immunohistochemistry marker can be a useful marker for diagnosis of RCC, specifically ccRCC type.
BACKGROUND: Educating dental students in practical skills are a difficult task that has become increasingly demanding since the outbreak of COVID-19. Today, the use of digital media plays an essential role in teaching practical skills. AIM: This study investigated the effect of educational videos on oral and maxillofacial surgery basics on dental student’s satisfaction. METHODS: Six subjects were chosen from the principles of oral and maxillofacial surgery, and according to the necessary standards, educational videos were made based on the needs assessment of students. Fellow attending evaluated and approved each video. Students were shown videos in six 2-h sessions. Students were given a researcher-created questionnaire with proven validity and reliability. Students filled out questionnaires to evaluate the impact of educational videos as well as the structure of educational videos. RESULTS: Two hundred and three students participated in this study in their 4th−6th years. In this study, 203 students in their 4th to the 6th year participated. Most students were satisfied with the structure of educational videos (73.9%); in general, 84.7% of students expressed their satisfaction with this method. Half of the students preferred video training over face-to-face training in oral and maxillofacial surgery (50.4%). Many students suggested that these videos be included in the curriculum (80.7%). CONCLUSION: Students’ overall satisfaction with the structure and impact of educational videos indicates that educational videos made and evaluated by dental professors can help teach practical topics as a part of the curriculum.
