Objectives: This study described the clinical and surgical characteristics of chronic otitis media patients with acquired middle ear cholesteatoma. Methods: Among 1790 patients with chronic otitis media detected during almost 10 years, 449 suffered from cholesteatoma. The clinical features and surgical data were investigated. Results: Among the chronic otitis media patients, 449 (25.0%) cases had cholesteatoma with a mean age of 32.2 ± 16.1 SD years, and 62.8% were male. The most common symptom was otorrhoea (53%), followed by hearing impairment (37.9%). Erosion of the facial nerve canal was observed in 33.1% of patients, dural plate erosion in 4.8% of cases, and labyrinthine fistula in 10.3% of patients. Moreover, ossicular chain erosion was observed with the highest frequency in incus (40%), followed by malleus (33%) and stapes (26%). Amongst the surgically treated patients, 59.3% underwent mastoidectomy with canal wall preservation, 29.7% underwent modified radical mastoidectomy, and radical mastoidectomy was performed in 11% of patients. Conclusions: Cholesteatoma was seen in about a quarter of patients with chronic otitis media. Based on our findings, cholesteatoma can be associated with serious complications such as facial nerve canal erosion (33.1%), dural plate erosion (4.8%), and labyrinthine fistula (10.3%). Regarding the functional importance of the hearing system and the high prevalence of disease complications, middle ear cholesteatoma needs long-term follow-up.","PeriodicalId":39157,"journal":{"name":"Shiraz E Medical Journal","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84621402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The present study evaluated the academic performance of the Tabriz Faculty of Management and Medical Informatics postgraduate students, an Iranian Center of Excellence in Health Management based on the Tennessee Academic Audit Model. Methods: This descriptive-cross sectional study was conducted in 2019 with the participation of educational managers and faculty members of the same faculties in two phases consisting of self-assessment and external evaluation. After contextualization, the Tennessee comprehensive higher education audit checklist was used. Data were studied descriptively, and the results were reported as frequency (percentage) and mean ± standard deviation. Analysis of variance (ANOVA) and Tukey’s post hoc tests were used to evaluate the significance of the difference in academic performance between the educational groups. t-test was also used to evaluate the difference in performance scores in self-assessment and external evaluation phases. A P-value < 0.05 was considered significant. Results: The participants’ performance in the self-assessment phase was moderate (total score: 5.32), and their performance in the external evaluation phase was weak (total score: 2.75). The best and the worst self-assessment scores were in the dimensions of “overall assessment” and “follow-up of previous academic audits,” respectively. In the external evaluation, the dimensions of “contributions to the program and university goals” and “follow-up of previous academic audits” had the best and worst performance scores, respectively.

Diabetes mellitus (DM) is associated with adverse clinical outcomes and high mortality in patients with COVID-19. Objectives: This study examined the frequency of BM, newly diagnosed hyperglycemia, and their impacts on hospitalized patients with COVID-19. Methods: This retrospective study examined 810 medical records of PCR-confirmed COVID-19 patients admitted to Razi Hospital, Ahvaz, Iran. The clinical presentations, severity, and impacts of COVID-19 were compared between patients with and without DM. Disease severity was determined based on the NEWS2 scoring system. Results: This study included 810 medical records of COVID-19 patients, of whom 326 had pre-existing DM, and 484 were non-DM. The rates of diabetes and newly diagnosed hyperglycemia were 40.2% and 11.2%, respectively. The most common underlying diseases were hypertension (35.3%), ischemic heart disease (17.9%), and chronic kidney disease (11.9%), which were higher in people with diabetes than non-diabetics. The rate of acute kidney injury was higher in patients with diabetes than in non-diabetics (30.7% vs. 19.2%; P < 0.001) and in patients with severe COVID-19 than in those whose disease was not severe (27.8% vs. 21.5%; P = 0.04).

However, dilation and curettage have been associated with hazards such as uterine rupture, heavy bleeding, and infection. Therefore, in recent decades, pharmacological therapies have become more widely accepted. Objectives: This research compared the medical abortion success rates of misoprostol/letrozole versus misoprostol/placebo. Methods: This randomized clinical study was conducted at Mashhad University of Medical Sciences hospitals between 2018 and 2019, involving pregnant women who were candidates for medical abortion. The study population was divided into two groups based on whether they had undergone cesarean section (CS). Each group was randomly assigned to either a control or an intervention group. In the CS group, there were 52 patients in the intervention group and 52 in the control group. The control group received a regimen of misoprostol and placebo, while the intervention group received a combination of misoprostol and letrozole. Results: There was no statistically significant difference in age (31.59 ± 5.6 vs. 31.06 ± 4.6, P value = 0.605), gestational age by ultrasound (11.20 ± 3.3 vs. 10.29 ± 2.6, P value = 0.135), or blood pressure between the control and intervention groups. However, the analysis showed a statistically significant difference in the rate of complete abortion (12 (23.5%) vs. 28 (54.9%), P value = 0.001) between the two groups. In the non-CS group, there was a significant difference in age between the control and intervention groups. The study analyses also revealed a significant difference in the rate of complete abortion between the two groups (24 (46.2%) vs. 36 (72.0%), P value = 0.008). Conclusions: Letrozole is recommended in combination with misoprostol for medical abortions because it increases the likelihood of complete abortion and reduces the duration of the abortion process.","PeriodicalId":39157,"journal":{"name":"Shiraz E Medical Journal","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82355615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This descriptive-analytical study was conducted from 2015 to 2017, based on the data from patients with definitive diagnoses of BCC in two university hospitals in Birjand. In this study, 85 patients with BCC were selected based on pre-defined inclusion criteria and then divided into two groups, including single and subsequent asynchronous lesions in another anatomic area. In this study, the information was collected by census method from diagnosed patients two years after surgery. The subsequent lesions in other anatomical areas were investigated, then tumor risk factors were compared in the two groups. Results: The mean age of the patients was 67.83 ± 12.29, and the youngest and the oldest patients were 38 and 92 years old, respectively. Among the studied patients, 75.3% had a history of sun exposure. The most common occupations of the patients were farmer, rancher, and housekeeper. Head and neck regions were involved in 96.5%. The patients with subsequent asynchronous BCC in another facial skin region were 10.6% (CI95: 4.06 - 17.14). These patients have been subject to several simultaneous risk factors in their medical history; most of them were farmers older than 65 years. Two patients experienced three lesions in three different anatomical regions at different times. There was no statically significant difference between the two groups regarding mean age (P = 0.47), gender (P = 0.73), pathologic subtype (P = 0.06), and other risk factors (P > 0.05).
