To overcome the magnesium’s high corrosion rate issue, triple polyvinylalcohol (PVA) coatings containinghydroxyapatite (HA) and 8-hydroxyquinoline (8-HQ) were prepared by two different methods of electrospinningand immersion. The formation of HA and Mg(8-HQ)2 layers during exposure to a corrosive mediumwas indicated by X-ray diffraction (XRD) and fluorescent images, respectively. Results showed thatthe electrospinning coating containing HA and 8-HQ, revealed a significant anti-corrosion performance(Rct = 7891, and 12,680 ohm cm2 in NaCl 3.5 wt.%, and simulated body fluid (SBF), respectively) comparedto the same composition immersion samples (Rct = 3231, and 3727 ohm cm2). The increment in anticorrosionperformance is caused by the release of HA and 8-HQ from the nanofibers. The problem of bacterialinfections in magnesium implants has been improved (reduction in bacterial-growth percentage= 90% in coating prepared by electrospinning method) by cleverly designing the triple coatingcontaining 8-HQ as an anti-bacterial compound.

Patient dissatisfaction following rhinoplasty: a 10-year experience in Iran
Farhad Ghorbani,Hanie Ahmadi,Ghazal Davar 대한악안면성형재건외과학회 2023 Maxillofacial Plastic Reconstructive Surgery Vol.45 No.-
Background The nose is one of the most prominent parts of the face and plays a significant role in peoples’ selfsatisfaction as well as quality of life. Rhinoplasty is considered as one of the most numerous and delicate cosmetic surgeries all around the world that can be performed for functional issues, esthetic issues, or both. In this study, we aimed to evaluate the dissatisfaction of patients who had undergone rhinoplasty surgery and inform the surgeons to improve the surgical techniques to prevent probable future complaints. Method This retrospective cross-sectional study was conducted to report various aspects of dissatisfaction of patients following rhinoplasty. All available files in the Fars Forensic Medicine Department between 2011 and 2020 were reviewed, and the required information was extracted. Results Out of 117 patients, 68.4% were females and 31.6% were males. Most of the patients were in the age range of 30–34 years. In terms of educational attainment, the highest frequency is associated with academically educated patients and the lowest with a diploma. The majority of cases filed for litigation less than 6 months after their rhinoplasty. The first rank among the factors of dissatisfaction with surgeries belonged to “respiratory problems” (36.8%) followed by “dissatisfaction with the general shape of the nose” (34.2%). Conclusion Our study shows that middle-aged female patients may be more difficult to satisfy. In general, at younger ages, patients complain about esthetics, and with aging, most patients feel dissatisfied with nasal function.

Analysis of hard tissue facial symmetry after unilateral mandibular reconstruction
Mohamad Saleh Khaghaninejad,Leila Khojastepour,Hanie Ahmadi,Saeid Tavanafar,Alireza Ebrahimi,Mohammad Mahjoori-Ghasrodashti 대한악안면성형재건외과학회 2021 Maxillofacial Plastic Reconstructive Surgery Vol.43 No.-
BackgroundThis study aimed to determine how successful reconstruction of the mandible can recover the symmetry. Materials and methodsAll patients who underwent surgical treatment for unilateral mandibular reconstruction in 4 years were retrospectively examined. Bilateral differences of gonion (GO) positions were measured in 3 dimensions based on immediate postoperative computed tomography. The data collected was analyzed in 3 ways: First, the comparison of bilateral differences of GO in 3 dimensions. Second, the mean Asymmetry Index in control subjects was used to divide all cases into three groups: “Symmetry,” “Asymmetry,” and “Marked asymmetry.” Third, “maximum normal asymmetry” was calculated, and all cases were categorized as below and above maximum normal asymmetry. The difference between two gonial angles was used to determine the amount of asymmetry. ResultsForty-seven patients and 47 normal adults were enrolled. The mean bilateral GO difference in the control group was higher than in the study group patients, but it was not statistically significant. The mean Asymmetry Index for the control group was not also significantly higher than the study cases. The study group was “Symmetric” in 78.7% of the cases whereas the control group in 91.4%, 19.1% of the study group and 8.5% of controls were “Asymmetric,” and 2.1% of study cases and 0% of controls were “Markedly Asymmetric.” Maximum normal asymmetry was 82.9% in the study group and 97.8% in the control group. The mean differences between the right and left gonial angles were higher in the study group, but it was not significant (P = 0.1). ConclusionsOur study’s results showed that bilateral symmetry in mandibular reconstruction patients was satisfactory and similar to the normal individuals.

Global Prostate Cancer Incidence and Mortality Rates According to the Human Development Index
Khazaei, Salman,Rezaeian, Shahab,Ayubi, Erfan,Gholamaliee, Behzad,Pishkuhi, Mahin Ahmadi,Khazaei, Somayeh,Mansori, Kamyar,Nematollahi, Shahrzad,Sani, Mohadeseh,Hanis, Shiva Mansouri Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.8
Background: Prostate cancer (PC) is one of the leading causes of death, especially in developed countries. The human development index (HDI) and its dimensions seem correlated with incidence and mortality rates of PC. This study aimed to assess the association of the specific components of HDI (life expectancy at birth, education, gross national income per 1000 capita, health, and living standards) with burden indicators of PC worldwide. Materials and Methods: Information of the incidence and mortality rates of PC was obtained from the GLOBOCAN cancer project in year 2012 and data about the HDI 2013 were obtained from the World Bank database. The correlation between incidence, mortality rates, and the HDI parameters were assessed using STATA software. Results: A significant inequality of PC incidence rates was observed according to concentration indexes=0.25 with 95% CI (0.22, 0.34) and a negative mortality concentration index of -0.04 with 95% CI (-0.09, 0.01) was observed. Conclusions: A positive significant correlation was detected between the incidence rates of PC and the HDI and its dimensions including life expectancy at birth, education, income, urbanization level and obesity. However, there was a negative significant correlation between the standardized mortality rates and the life expectancy, income and HDI.
