Therefore, this study aimed to evaluate the role of endothelin-1 and its A receptor in dental lamina in different stages of tooth development. Materials and Methods: This cross-sectional study included 33 fetal samples that were divided into three groups regarding gestational age. All samples were then stained by immunohistochemistry. Subsequently, the analysis was conducted in SPSS software (version 20) through the two-way ANOVA and Tukey's tests to examine the differences between the variables. A p-value less than 0.05 was considered statistically significant. Results: There was a significant difference between the gestational age and the expression level of endothelin-1 in dental lamina (P<0.001). In addition, a significant relationship was observed between age and anatomic area (P<0.001). There was also a significant difference between the gestational age and the expression level of endothelin-1 receptor (ETAR) in dental lamina (P<0.001). A significant association was found between gestational age and anatomic area (P<0.001). Conclusion: The expression levels of endothelin-1 and its receptor (ETAR) in each jaw were higher in anterior dental lamina, compared to posterior dental lamina. These results may confirm the role of endothelin-1 and its receptor in cell proliferation, differentiation of dental lamina, and calcium ion transport during tooth development.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43018398","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}

The present study aimed to evaluate the serum levels of vitamin D, ferritin, and hemoglobin in patients with attempted suicide referring to hospitals and compare them with the control group. Materials and Methods: A comparison was made between the serum levels of vitamin D, ferritin, and hemoglobin of 60 suicidal patients referring to Ali ibn Abitaleb hospital of Rafsanjan from March to september 2020 and those of 60 relatives of selected patients with no history of suicide. The control group completed the Beck Suicide Thought Questionnaire (BSTQ). Chisquare, ANOVA, independent t-test, Mann-Whitney U test, and KruskalWallis statistical tests were used to analyze the data. Results: The serum level of vitamin D in Patient with attempted suicide was lower, compared to that in controls (P=0.025). Among the age group of 1535 years, serum levels of vitamin D were lower than those in the control group (P=0.039). Moreover, serum ferritin level in the attempted suicide group was lower than that in the control group (P=0.003). Serum ferritin level was significantly lower among the suidide attempters aged 15-15 years (P= 0.003), men with attempted suicide (P= 0.003) and suicidal women (P= 0.045), as compared to the control group. Conclusion: As demonstratedd by the results of the present study, vitamin D deficiency and anemia can be two major risk factors for suicide. Therefore, it is necessary to identify and treat these deficiencies in people with psychological disorders, such as depression.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43204676","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}

Although the exact role of vitamin D in this disease is still not clearly understood, some studies have shown lower serum levels of vitamin D in seborrheic dermatitis patients. This study aimed to investigate the correlation between vitamin D deficiency and seborrheic dermatitis. Materials and Methods: This cross-sectional case-control study was conducted in Sina Hospital, Hamadan, Iran. The study sample included 39 seborrheic dermatitis patients (case group) and 39 healthy individuals (control group) who were matched in terms of gender and age. The groups were then compared regarding serum vitamin D level. Statistical analysis was performed in SPSS software (version 16.0; SPSS Inc.Chicago, IL). Results: There were no significant differences between the two groups in terms of age, gender, educational level, place of residence, and occupational status. The mean serum levels of vitamin D in the case and control groups were 11.82±5.56 and 21.38±6.79ng/ml, respectively (P=0.001). Furthermore, in the case and control groups, 18 (46.2%) and 1 (2.6%) individuals had vitamin D deficiency; 20 (51.3%) and 34 (87.2%) cases had inadequate vitamin D levels; and 1(2.6%) and 4 (10.3%) subjects had adequate levels of vitamin D, respectively. Therefore, the serum level of vitamin D was significantly lower in the case group, compared to the control group (P=0.001). Moreover, the serum level of vitamin D did not correlate with the duration and severity of seborrheic dermatitis disease (P>0.05). Conclusion: According to the findings of this study, patients with seborrheic dermatitis had lower serum vitamin D levels, compared to the general population, which may be related to the pathogenicity of the disease.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45769415","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}

The present study aimed to histopathologically determine the types of gynecological cancers in patients admitted to Baqiyatallah Hospital over a nine-year period. Materials and Methods: This retrospective study was conducted based on hospital data of patients who were admitted to Baqiyatallah Hospital and underwent any procedure, treatment, and diagnosis of gynecologic cancers during 2011-2019. Patients' information was extracted from hospital integrated archiving system. Results: A total of 404 patients were diagnosed with gynecological cancers between 2011 and 2019. Among these cancers, ovarian cancer with 212 (52.5%) patients was the most common gynecological cancer. Among patients with ovarian cancer, Serous Adenocarcinoma and Endometrioid Adenocarcinoma with 137 (64.6%) and 29 (13.7%) cases had the highest frequency of pathology, respectively. The mean (standard deviation) age of the patients with gynecological cancer was 55.88 (11.51) years. During the study period, there was a relatively increasing trend for ovarian cancer during 2011-19. Conclusion: ovarian cancer with Serous Adenocarcinoma was the most common cancer diagnosed in patients admitted to Baqiyatallah Hospital during 2011-19. The relatively increasing trend of this type of female genital cancers during this 9-year period and the observed age pattern highlight the importance of implementing timely screening and treatment programs.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46017223","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}

Severe preeclampsia has many maternal and neonatal complications that are more prevalent in early-onset preeclampsia. The present study aimed to determine the prevalence of maternal and neonatal outcomes of expectant management of severe preeclampsia before 34 weeks of gestation. Materials and Methods: In this retrospective descriptive study, the medical records of 55 mothers who had severe preeclampsia before 34 weeks of gestation and underwent expectant management and those of their neonates within 2014-2019 in Kashan, Iran, were reviewed. The information extracted from the medical records included maternal and neonatal demographic variables and outcomes. All data were analyzed in SPSS software (version 16) using descriptive and inferential statistics. The p-values of less than 0.05 were considered significant. Results: In this study, the rates of seizure, post-partum hemorrhage, intensive care unit admission, and platelet decline were 5.5%, 1.8%, 3.6%, and 7.3%, respectively. Moreover, 10.9% of mothers had renal failure, and therefore, elevated liver enzymes and hemolysis. Among the neonates, 44.7% and 12.7% of the cases had respiratory distress syndrome (RDS) and low Apgar scores, respectively. It was also revealed that 6.4% of the neonates had convulsions and pneumothorax (PTX), and neonatal mortality was observed in 6.4% of them. No significant relationship was observed between maternal outcomes and gestational age and between neonatal outcomes and the number of deliveries (P>0.05). However, renal failure outcomes had a significant relationship with the number of deliveries (P=0.023), meaning that all mothers with renal failure were nulliparous. It was found that gestational age had a significant relationship with the outcomes of neonatal death, low 5-minute Apgar score, low birth weight, RDS, and PTX (P<0.05); in other words, lower gestational age led to higher mentioned neonatal outcomes.
