Introduction: Diagnostic X-ray is one of the ionizing radiations, the level of radiation dose received by the patient during medical examination is essential to prevent cancer risks. The aim of this study is to calculate entrance surface dose (ESD) and effective dose (ED) were estimated during chest, and lumber spine for adult patients in three hospitals in Erbil, using NOMEX MULTIMETER and PCXMC software. Material and Methods: The study was conducted in three public hospitals, in Erbil on (250) adult patients, whose ages between (18-70) years, based on the results study, ESD and ED were calculated for chest (PA, lateral), and lumbar spine (AP, lateral) examinations. NOMEX MULTIMETER (PTW, Freiburg), used in measurement of tube voltage, dose, dose rate, time product current, and total filtration automatically during examination. ED was calculated by using PCXMC software (version 2.5). Results: The results of this work are compared with published international literatures. The mean entrance skin dose for examinations of chest (PA, Lat), and lumber spine (AP, Lat) 1.02, 1.06, 2.61 and 3.92 mGy respectively. ED value was from 0.08, 0.19, 0.32, and 0.33 mSv, for chest (PA, Lat), and lumber spine (AP, Lat), respectively. Conclusion: The ESD, and ED were calculated in this work were found to be agreement with the published reference values for chest, and lumber spine set by international levels. ALARA principle should be considered by radiographer, to reduce absorbed dose of adults’ patient undergoing imaging radiography.

Introduction: So far, a lot of attempts have been carried out to find antimicrobial compounds. In this study, it was also tried to investigate the antibacterial effects of Achillea millefolium on standard Klebsiella, S. pyogenes, and oral bacterias strain. Material and Methods: The aerial parts of Achillea millefolium were used and the aqueous, ethanolic, methanolic, acetone and hydroethanolic extracts were prepared. After the preparation of standard strains of Klebsiella, S. pyogenes, and oral bacterias and sterilization of extracts by the Millipore filter, the antibacterial effects of these extracts on the mentioned microorganisms were assessed by minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and well diffusion at the concentration 50 mg/ml. The test was repeated three times for each bacterium. Results: It was exposed that aqueous extract of Achillea millefolium had the most distinguished antimicrobial effects against all studied strains and methanolic extract had antimicrobial effects only on S. pyogenes. MIC and MBC of effective extracts were the basic concentration (50mg/ml), and non-growth zone was not observed in other serial dilution in case of all bacteria. Conclusion: The Achillea millefolium can be admitted as an antibacterial medicinal herb. Thus, it can be concluded that after evaluating their effects in vitro, Achillea millefolium can be utilized as an alternative to the routine chemical drugs.

Introduction: Understanding the pattern of infections in the intensive care unit and the correct pattern of antibiotic use is vital in reducing mortality. Identification of risk factors for nosocomial infection and preventive approaches can be effective in reducing the incidence. This study aimed to evaluate the intensive care unit (ICU) acquired infection. Material and Methods: This cross-sectional study was performed on patients admitted to the ICU of Sayyad Shirazi Hospital during 2016-18. All patients' information recorded and analyzed by SPSS version 16. Results: In this study, the nosocomial infection rate was 3.5%, mostly in individuals over 60 years old. Most of the positive cultures were from two sources of urine and then blood. The organisms observed in nosocomial infections were Escherichia coli (16.9%), Staphylococcus epidermis (11.5%), Enterococci, and Enterobacter. The most commonly used antibiotics were vancomycin and then meropenem. Antibiogram results indicated the highest antibiotic resistance (100%) to cefazolin, piperacillin and clindamycin, and 96.8% to ceftriaxone. Vancomycin and amikacin had the lowest resistance. Conclusion: According to the results of this study, the incidence of nosocomial infection is unavoidable, and its control is the most important health goals of medical centers. Proper treatment interventions are needed to reduce the impact of nosocomial infection.

Introduction: Recently, a new strain of coronaviruses, which originated from Wuhan City, Hubei Province, China has been identified. According to the high prevalence of new coronavirus, further investigation on the clinical and paraclinical features of this disease seems essential. Hence, we carried out this systematic review and meta-analysis to figure out the unknown features. Methods: This study was performed using databases of Web of Science, Scopus and PubMed. We considered English cross-sectional and case-series papers which reported clinical, radiological, and laboratory characteristics of patients with COVID-19. We used STATA v.11 and random effect model for data analysis. Results: In the present meta-analysis, 32 papers including 49504 COVID-19 patients were studied. The most common clinical symptoms were fever (84%), cough (65%) and fatigue (42%), respectively. The most common radiological and paraclinical features were bilateral pneumonia (61%), ground-glass opacity (50%), thrombocytopenia (36%) and lymphocytopenia (34%). The study also showed that the frequency of comorbidities and early symptoms was higher in critically severe patients. Moreover, we found the overall mortality rate of three percent. Conclusion: According to that there are many cases without Computed Tomography Scan findings or clear clinical symptoms, it is recommended to use other confirming methods such RNA sequencing in order to identification of suspicious undiagnosed patients. Moreover, while there is no access to clinical and paraclinical facilities in in public places such as airports and border crossings, it is recommended to consider factors such as fever, cough, sputum and fatigue.
导语:近日，一株原产于中国湖北省武汉市的新型冠状病毒被发现。鉴于新型冠状病毒的高流行率，有必要进一步研究该病的临床和临床外特征。因此，我们进行了这项系统综述和荟萃分析，以找出未知的特征。方法:本研究采用Web of Science、Scopus和PubMed数据库。我们参考了报道COVID-19患者临床、放射学和实验室特征的英文横断面和病例系列论文。我们使用STATA v.11和随机效应模型进行数据分析。结果:本meta分析共纳入32篇论文，49504例COVID-19患者。最常见的临床症状分别是发热(84%)、咳嗽(65%)和疲劳(42%)。最常见的放射学和临床旁特征是双侧肺炎(61%)、毛玻璃混浊(50%)、血小板减少(36%)和淋巴细胞减少(34%)。研究还表明，危重患者出现合并症和早期症状的频率更高。此外，我们发现总体死亡率为3%。结论:鉴于有很多病例没有ct扫描结果或临床症状不明显，建议采用RNA测序等其他确认方法，以识别可疑的未确诊患者。此外，虽然机场和过境点等公共场所无法使用临床和临床辅助设施，但建议考虑发烧、咳嗽、痰和疲劳等因素。
