Abstract
Background: Nowadays, the COVID-19 pandemic has become a global problem that new methods must be used to prevent it. The virus is highly contagious and is mainly transmitted through the air. Ozone is a powerful oxidant that can be used to inactivate a wide range of viruses that may be resistant to other disinfectants. The purpose of this study was to review the use and effect of ozone in inactivating indoor viruses.
Methods: To conduct this review study, the keywords such as ozone, virus and air were used to search the PubMed and Scopus databases. Articles were searched from 2010 to 2020. As a result of the search, 57 articles in this field were selected and their content and results were used in this review study. 
Results: This review study showed that ozone has been successfully used to prevent several viral diseases such as COVED-19. In addition, some viruses, such as coronaviruses, contain sulfhydryl functional groups containing cysteine and tryptophan that react better with ozone gas. The infected person's sneezing may result in the formation of 40,000 droplets in the air. The droplets can be transferred to the nearest surface up to approximately 2 meters before falling and also may remain in the air for 30 hours.
Conclusion: The use of ozone gas has many potential applications in inactivating viruses in enclosed spaces. Given the importance of virus-containing aerosols in the transmission of COVED-19, ozone can be a promising way to prevent the disease. The degree of inactivation of viruses by ozone gas depends on the gas concentration, contact time, temperature, humidity and type of virus. In general, studies in this field have shown the use of ozone gas in preventing the spread of viral diseases such as COVED-19. Necessary safety measures and precautions are also recommended in using this gas.

Abstract
Background: Psychosocial improvements of successful strabismus surgery have been reported in previous studies. But the effect of strabismus surgery on the emotional intelligence of patients is unclear. The aim of this study was to evaluate the effect of strabismus surgery on emotional quotient in patients referring to Imam Khomeini Hospital, Ahvaz.
Methods: This prospective interventional study conducted on patients underwent strabismus surgery in Imam Khomeini Hospital, Ahvaz during May 2021 to March 2022. A total of 38 patients between 8-37 years were included. Patients with previous surgery were excluded. All subjects were evaluated before and three months after successful strabismus surgery. Three months post-surgery the improvement of emotional quotient, self-esteem, body image, social anxiety and social avoidance were evaluated and compared with previous surgery. All data were analyzed by SPSS (V25). P-Value less than 0.05 was considered as significant level.
Results: 38 subjects including 18 males (47.4%) and 20 females (52.6%) were included. The mean age of patients was 18.11±9.33 years old. Our results showed that compared with before surgery, significant improvements were noted after surgery, within the emotional quotient subscales including self-awareness (P=0.016), self-regulation (P<0.0001), self-motivation (P<0.0001), empathy (P<0.0001), social skills (P<0.0001) and emotional quotient total score (P<0.0001). Further analysis revealed statistically significant improvements in body image (P<0.0001), social anxiety (P=0.004) and social avoidance (P=0.002). The result showed that the improvement of emotional quotient after strabismus surgery was significantly higher in the age group of less than 12 years (P<0.0001). No significant difference was fund between two  genders for emotional quotient subscales (P>0.05).
Conclusion: The results of this study showed a significant improvement in the psychosocial factors including emotional quotient, body image, social anxiety and social avoidance after strabismus surgery. This result suggests that beyond functional and cosmetic improvements, successful strabismus surgery can result in improved emotional quotient and social anxiety, with the greatest effect noted in younger patients.

Abstract
Background: Rhinoplasty is a challenging and complex surgery because it is designed to meet the unique needs of the patient. In rhinoplasty surgery, many factors contribute to achieving the desired result. These factors include the surgeon's care and observation, analysis of the existing anatomy, choice of surgical technique, degree of soft tissue and cartilage trauma, amount of bleeding, quality of surgical instruments and anesthesia, and anything that helps reduce bleeding.
Methods: This double-blind study was conducted on 50 patients aged 18 to 45 years undergoing septorhinoplasty surgery referred to Motahari Hospital in Jahrom city in 2022. Patients were randomly divided into dexmedetomidine and control groups. The degree of sedation, bleeding and surgeon satisfaction were evaluated and recorded. Data analysis was performed using SPSS software, version 21 (IBM SPSS, Armonk, NY, USA) and descriptive statistics (mean, standard deviation, percentage, number, frequency) and inferential statistical tests (Mann-Whitney U test, Kruskal-Wallis, t-test, chi-square test). The significance level in all tests was considered P<0.05.
Results: The majority of patients in the study groups were female and the mean age of patients in the dexmedetomidine group was 34.36±7.33 years and in the control group was 36.60±9.59 years. The study groups were similar in terms of age and body mass index (P<0.05). The frequency of patient sedation in the dexmedetomidine group was lower than the control group, but it was not statistically significant (P<0.05). The results showed that at the beginning of the operation and 90 minutes later, the satisfaction level of the patient surgeon in the dexmedetomidine group was significantly better than the control group (P<0.001). In the dexmedetomidine group, the field of view of the surgeon was relatively clear and completely clear. The amount of bleeding in the dexmedetomidine group was lower than the control group, but it was not statistically significant (P<0.05).
Conclusion: Dexmedetomidine increased the surgeon's satisfaction by reducing bleeding and improving the surgeon's visual field. Therefore, this drug can be used as an anesthetic aid in surgery.

Abstract
Background: Hemodynamic instability is a significant perioperative complication that can threaten surgical outcome through various mechanisms: exacerbating intraoperative bleeding, compromising visibility of the surgical field, and elevating immediate and delayed postoperative complication risks. In septorhinoplasty, a procedure with challenging hemodynamic control due to the nasal anatomy's complexity of vessels, these effects are particularly relevant. This study examines the modulation of important hemodynamic parameters (SBP, DBP, MAP, HR, and SpO₂) by intravenous dexmedetomidine while ensuring cardiovascular stability and dose-dependent effects and optimal timing of administration at different phases of surgery. The findings aim to offer evidence-based recommendations for hemodynamic control in rhinoplasty surgery, which can reduce rates of complications and improve recovery profiles.
Methods: A randomized, double-blind clinical trial was conducted involving 50 eligible patients (aged 18-45 years) scheduled for septorhinoplasty at Ostad Motahari Hospital, Jahrom, during May-September 2023. Participants were randomly allocated to either a dexmedetomidine or control group. Collected data encompassed demographic characteristics (age, gender, BMI=Body mass index) and hemodynamic parameters (systolic/diastolic blood pressure, mean arterial pressure, heart rate, and oxygen saturation). The data were analyzed using SPSS software, version 21 (SPSS Inc., Chicago, IL, USA). Descriptive statistics (mean, standard deviation, percentage, count, and frequency) and inferential statistical tests (Mann-Whitney U test and independent t-test) were applied. A significance level of P < 0.05 was considered for all statistical analyses.
Results: The dexmedetomidine group demonstrated statistically significant variations in hemodynamic parameters (SBP, DBP, MAP, HR) from pre-induction through post-recovery phases (p<0.001). Significant between-group differences in blood pressure metrics were observed at all measured intervals following induction (1, 5, 15, 30, 60 minutes) and during recovery periods (p<0.05), with the dexmedetomidine group consistently showing lower values. Comparison between the intervention and control groups revealed no statistically significant differences in heart rate and oxygen saturation (O₂ sat) levels (except during recovery time).
Conclusion: The results of this study indicate that dexmedetomidine administration had a significant effect on reducing systolic blood pressure, diastolic blood pressure, and MAP compared to the control group, with this reduction being evident at all measured time points from post-induction to post-recovery. These findings suggest that dexmedetomidine can be effectively used as a blood pressure-lowering agent during surgery without significantly affecting heart rate or the patient's blood oxygen levels.
