Objective: To evaluate awareness of medical and dental students of Kerman University of medical science about the infection and vaccination of the human papilloma virus. Material and Methods: This descriptive cross-sectional study was conducted on 290 medical and dental students. The data were collected using a questionnaire, which consisted of demographic data, and awareness-raising questions whose validity and reliability were confirmed. Mann-Whitney U and linear regression test were used for statistical analysis, and significance level of 0.05% was measured. Results: From 290 participants, 44.5% were male, 69.7% were single, 51.7% were medical students and 92.4% of individuals had awareness about HPV. The most common source of information (83.7%) was textbook. 39.9% of respondents were not familiar with the HPV vaccine and 62.1% tended to be vaccinated. Most of individuals (69.4%) were willing to pay a vaccination fee of less than $10. Most of respondents were not aware of HPV vaccination in Iran (68.3%). The mean score of knowledge was 6.1 ± 2.4. There was a statistically significant relationship between gender, field of study and marital status with mean score of knowledge (p<0.05). Conclusion: The students' knowledge was moderate. The awareness of men and women about HPV was poor. Further studies are recommended on other community groups, especially young people. Risk groups should be identified and referred to the relevant organs for vaccination.
Background:It has been demonstrated that HER3 plays an important role in some human cancers and the HER3 expression is associated with worse survival in solid tumors.Objectives:This study was conducted to compare HER3 expression in epithelial lining of radicular cysts (RCs), dentigerous cysts (DCs) and odontogenic keratocysts (OKCs).Materials and Methods:This was a descriptive-analytical study, which assessed all 57 paraffin blocks of RCs, DCs and OKCs (21 RCs, 16 DCs, 20 OKC) from pathological archive of Dentistry College of Zahedan, Iran. The HER3 expression in cytoplasm and membrane was examined by immunohistochemical method. The data collected was analyzed using SPSS16 by ANOVA and Chi-square. P < 0.05 was considered as statistically significant.Results:The HER3 expression had positive results in 52.4% of OKC, 50% of DC and only 20% of RC samples. There was a significant difference between HER3 expression in OKCs and RCs.Conclusions:The HER3 expression in developmental odontogenic cysts was higher than that in inflammatory odontogenic cysts. The higher rate of HER3 expression in OKC may justify inherent growth potential, stimulation-independent proliferation capability, invasive growth and high recurrence rate of the cyst accepted today as a tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
