This pathogen is one of the most important opportunistic pathogen agents of nosocomial infections, such as pneumonia, urinary tract infections, invasive infections, and surgical site infections. This study aimed to investigate the biofilm producer strains among different clinical isolates of Klebsiella pneumoniae. Materials and Methods: This observational study was conducted on 230 clinical samples with bacterial infection. The selective culture media and biochemical tests were used for the identification of Klebsiella pneumoniae isolates. Crystal Violet assay and PCR were also used to characterize biofilm strains. Results: Out of 230 samples collected from different specimens, 100 isolates (43.47%) of Klebsiella pneumoniae were identified by biochemical tests. Of these, 58 (58%) and 42 isolates (42%) were isolated from the male and female individuals, respectively. The phenotypic method showed 2, 27, 41, and 30 isolates as strong biofilm producers, medium biofilm producers, weak biofilm producers, and non-biofilm producers, respectively. The frequency of genes were reported as wzm (47%), markA (69%), pgaAa (65%), and wbbm (47%), respectively. Conclusion: The markA gene plays an important role in biofilm formation and can identify different biofilms in Klebsiella pneumoniae strains. It is also possible to identify bacteria with weak, moderate, and strong biofilms.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45121433","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 purpose of this study was to measure this proportion in the assessment of damage through interventions in patients with non-emergency angioplasty. Materials and Methods: A prospective cohort study was performed on 122 patients referring to Hamadan Farshchian Heart Center, Hamadan, Iran, during 2017 for selected angioplasty. Patients were divided into two groups according to the ratio of neutrophil/ lymphocyte. Data were collected through a checklist and blood test results, including neutrophil/lymphocyte ratio, erythrocyte sedimentation rate (ESR), C-reactive Protein (CRP), Creatine kinase-MB (CKMB), and troponin before angioplasty, as well as 6 and 12 h after angioplasty. The Chi-square test and independent t-test were performed using Stata software (version 14). Results: There was no significant difference between the ESR levels in the two groups before the angioplasty (P=0.431). However, there were significant differences between the two groups 6 h (P=0.001) and 12 h after the angioplasty (P=0.011). There was no significant difference between the blood level of troponin in both groups before (P=0.310) and 6 h after (P=0.186). However, there was a significant difference between the two groups 12 h after the angioplasty (P=0.042). Conclusion: The results showed that an increase in the level of troponin elevated neutrophil/lymphocyte ratio and ESR.

The nickel-titanium rotary files result in fewer errors during the preparation of curved canals. This study aimed to compare the transportation of Neolix and Reciproc rotary systems in curved canals using cone beam computed tomography (CBCT). Materials and Methods: In this experimental study, 70 extracted curved premolar teeth from patients referred to dentistry faculty were assigned into two groups (n=35). The preparation of the canals was performed by the Neolix and Reciproc rotary systems. Remaining dentin thickness, transportation, and canal-centering ratio were evaluated and compared using CBCT images before and after the instrumentation. The data were analyzed in SPSS software (version.19) through ANOVA, independent t-test, and paired t-test. Results: There was a significant difference in terms of remaining dentin thickness in three sections of 3, 5, and 7 mm from the apex, before and after the instrumentation regarding the level of mesiodistal and buccolingual. However, no significant difference was observed in terms of the transportation in three sections of 3, 5, and 7 mm from the apex in both Neolix and Reciproc systems. Conclusion: According to the results, both Neolix and Reciproc rotary systems showed high efficacy in root canal shaping. The amount of transportation in these systems during preparation of curved canals was very low leading to the protection of canal-centering ratio.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49583286","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}

Due to ultrasonic changes in the corneal structure caused by keratoconus disease, its rigidity and biomechanical properties are subject to some changes. In this regard, the present study was conducted to determine the correlation of biomechanical features of keratoconus patients with the severity of the disease. Materials and Methods: The case group was selected from the patients with keratoconus who referred to the Corneal Clinic of Nikookari Hospital in Tabriz and the controls had no eye diseases. Corneal biomechanics, corneal hysteresis, and corneal resistance factor were evaluated in all the samples using an ocular response analyzer device. Results: The present study was carried out on 213 keratoconus eyes and 179 normal eyes. The mean scores of corneal hysteresis were obtained at 13.49±1.34 and 7.67±1.01 mmHg for normal and keratoconus eyes, respectively, which were significantly different between the two groups. The differences between the corneal hysteresis of mild (8.86 mm Hg), moderate (8.30 mm Hg), and severe (7.10 mm Hg) keratoconus eyes were also significant. The mean scores of the corneal resistance factor were reported as 12.68±1.15 and 7.36±1.07 mmHg for normal and keratoconus eyes, respectively, which were significantly different between the two groups. The differences between the corneal resistance factor of mild (8.55 mm Hg), moderate (8.05 mm Hg), and severe (6.76 mm Hg) keratoconus eyes were also significant.

In spite of the low prevalence of these conditions, they are of utmost significance due to their catastrophic complications and mortality. The SJS and TEN are mostly caused by a reaction to a drug; however, in some cases, they result from infections. The aim of this study was to investigate the epidemiologic, etiologic, and clinical characteristics of the patients admitted to Sina Hospital in Hamadan, Iran, due to SJS and TEN during a 16-year period. Materials and Methods: This cross-sectional descriptive study was conducted on the patients with SJS and TEN admitted to Sina Hospital during the last 16 years (i.e., 2002-2018). The data analyzed in the present study included age, gender, causative drug, length of hospital stay, received treatment, and complications. Results: A total of 47 patients, consisting of 21 males and 26 females, were investigated in this study. Out of the 47 patients, 34, 9, and 4 cases were diagnosed with SJS, TEN, and SJS/TEN overlap, respectively. Regarding the etiology of these conditions, 45 cases (95.7%) were drug-related, while the remaining 2 cases were caused by reasons other than drugs. The most common causative drugs were antimicrobials (36.1%), followed by antiepileptics (27.6%) and nonsteroidal anti-inflammatory drug (17 %). Furthermore, there one case caused by reaction to allopurinol, and another case resulted from reactions to rabies vaccine. The remaining cases were either non-drug related or multi-drug related. The most common complications were infections (21.2%), followed by ocular problems (19.1%) and gastrointestinal bleeding (2.1%). Conclusion: As the findings indicated, antimicrobials were the most common causative drugs of SJS and TEN. The physicians should be aware of the clinical manifestations of SJS and TEN with regard to the severe complications of these conditions, including ocular damages, and their risk of mortality. Moreover, it is required to enhance public awareness regarding the avoidance of self-medication with antimicrobial drugs.","PeriodicalId":52678,"journal":{"name":"pzshkhy blyny bn syn","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49430593","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}
