Background and Objective: The role of biofilm formation by bacteria has been considered as an important stage in the pathogenesis of Klebsiella pneumoniae. 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.

Background and Objective: The high ratio of neutrophils to lymphocytes is a predictor of the risk of myocardial infarction in people who have coronary artery angiography. 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. However, there was no significant difference in CRP and CKMB levels, although there were significant changes in clinical status.
背景与目的:中性粒细胞与淋巴细胞的高比值是冠状动脉造影患者心肌梗死风险的一个预测指标。本研究的目的是在评估非紧急血管成形术患者通过干预造成的损害时测量这一比例。材料和方法:一项前瞻性队列研究对2017年在伊朗Hamadan Farshchian心脏中心就诊的122例患者进行了选择性血管成形术。根据中性粒细胞/淋巴细胞比例将患者分为两组。通过检查表和血液检查结果收集数据,包括血管成形术前以及血管成形术后6和12小时的中性粒细胞/淋巴细胞比率、红细胞沉降率(ESR)、c反应蛋白(CRP)、肌酸激酶- mb (CKMB)和肌钙蛋白。采用Stata软件(版本14)进行卡方检验和独立t检验。结果:两组血管成形术前ESR水平比较,差异无统计学意义(P=0.431)。然而,两组在血管成形术后6 h (P=0.001)和12 h (P=0.011)有显著差异。两组治疗前(P=0.310)与治疗后6 h (P=0.186)血钙蛋白水平比较,差异无统计学意义。但两组在血管成形术后12 h差异有统计学意义(P=0.042)。结论:肌钙蛋白水平升高可提高中性粒细胞/淋巴细胞比值和ESR。然而,尽管临床状态有明显变化,但CRP和CKMB水平无显著差异。

Background and Objective: Lung cancer is one of the most common types of cancer and the main reason of cancer-caused mortality in Iran. The awareness of cancer epidemiologic and pathologic characteristics helps to prevent the prevalence and incidence of cancer. Materials and Methods: This comparative descriptive study was conducted on patients with lung cancer referring to Ekbatan and Shahid Beheshti Hospitals during 2001-2016. Risk factors as well as clinical and demographic data were collected from medical records. Results: The mean age of the patients was 61.11 ±12.23 years and 166 patients (83%) were male. A total number of 120 (66.7%) patients lived in urban areas. The frequency of patients who had a positive history for consumption of opioid, industrial drugs, cigarette, and hookah were 2%, 0%, 42.2%, and 1%, respectively. The most common symptoms were cough and dyspnea. The time interval between the appearance of clinical signs and diagnosis was 5.32 months. The most common paraneoplastic symptom was bone pain (45.5%), and the most frequent pathologic form was squamous cell carcinoma (33.5%). The right upper lobe (27.5%) and left upper lobe (23.5%) were the most common lobes. Conclusion: Since the time interval between clinical signs and diagnosis was long and squamous cell carcinoma was the most common type of cancer, it is important to control risk factors, specifically smoking, to prevent cancer.

Background and Objective: The preparation of the root canal (i.e., cleaning and shaping) is the main step in the endodontic treatment. 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.
背景与目的:根管预备(即清洁和塑形)是根管治疗的主要步骤。镍钛旋转锉在弯曲管的制备过程中误差较小。本研究旨在使用锥形束计算机断层扫描(CBCT)比较Neolix和往复式旋转系统在弯曲管中的传输。材料和方法:在本实验研究中,将70颗从牙科教师那里拔出的弯曲前臼齿分为两组(n=35)。运河的准备工作由Neolix和往复式旋转系统完成。使用CBCT图像评估和比较器械前后的剩余牙本质厚度、运输和管中心比率。数据在SPSS软件(19版)中通过方差分析、独立t检验和配对t检验进行分析。结果:在距离根尖3、5和7mm的三个切片中,在器械前后,就近中、颊舌水平而言,剩余牙本质厚度存在显著差异。然而,在Neolix和往复式系统中,在距离顶点3、5和7mm的三个部分的运输方面没有观察到显著差异。结论:根据结果,Neolix和往复式旋转系统在根管成形方面均显示出较高的疗效。在弯曲运河的准备过程中,这些系统中的运输量非常低,这导致了对运河中心比的保护。

Background and Objective: Keratoconus is a disorder in cornea characterized by constant thinning and prominence that can result in vision defect. 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. Conclusion: The obtained results of the present study showed that corneal hysteresis and corneal resistance factor were lower in keratoconus eyes, compared to those in normal eyes and decreased with the severity of the disease.

Background and Objective: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe and potentially life-threatening reactions. 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.
背景与目的:史蒂文斯-约翰逊综合征(SJS)和中毒性表皮坏死松解症(TEN)是一种严重且可能危及生命的反应。尽管这些疾病的发病率很低,但由于其灾难性的并发症和死亡率,它们具有极其重要的意义。SJS和TEN主要是由对药物的反应引起的;然而,在某些情况下,它们是由感染引起的。本研究的目的是调查伊朗哈马丹Sina医院16年来因SJS和TEN而入院的患者的流行病学、病因和临床特征。材料和方法:本横断面描述性研究对新浪医院过去16年(即2002-2018年)收治的SJS和TEN患者进行了研究。本研究分析的数据包括年龄、性别、致病药物、住院时间、接受的治疗和并发症。结果:本研究共调查了47名患者,包括21名男性和26名女性。在47例患者中,34例、9例和4例分别被诊断为SJS、TEN和SJS/TEN重叠。关于这些疾病的病因,45例(95.7%)与药物有关,其余2例由药物以外的原因引起。最常见的致病药物是抗菌药物(36.1%),其次是抗癫痫药物(27.6%)和非甾体抗炎药物(17%)。此外,有一例由别嘌呤醇反应引起,另一例由狂犬病疫苗反应引起。其余病例要么与药物无关,要么与多种药物有关。最常见的并发症是感染(21.2%),其次是眼部问题(19.1%)和胃肠道出血(2.1%)。医生应了解SJS和TEN的临床表现以及这些疾病的严重并发症,包括眼部损伤及其死亡风险。此外,还需要提高公众对避免使用抗微生物药物自行用药的认识。

Background and Objective: Chronic obstructive pulmonary disease (COPD) is a worldwide health problem with increasing prevalence. It is often associated with negative health outcomes, including depression. Therefore, the aim of this study was to determine the prevalence of depression in patients with COPD. Materials and Methods: This cross-sectional study with a descriptiveanalytic design was conducted on 103 patients referring to the respiratory disease clinic and admitted to the pulmonary disease department of Shahid Beheshti teaching Hospital, Hamadan, Iran from April to September 2018. The inclusion criteria were the diagnosis of severe and very severe COPD according to the medical history, physical examination, and standard spirometric methods. The patients with lack of bereavement, trauma, and the use of antidepressant drugs were excluded from the study. Depression levels were measured using 21-items Beck II depression questionnaire. Results: The results of the study showed that 57 patients (55.3%) were males and 46 cases (44.7%) were females. The majority of the subjects (33%) were in the age group of 50-59 years old. According to the results, the prevalence of depression in the study population was 66%. There was a significant relationship between spirometric parameters of forced expiratory flow at 2575% of the pulmonary volume, forced expiratory volume at 1 second and COPD severity (P=0.024, P=0.003). Conclusion: With regard to the high prevalence of depression among people with severe and very severe COPD, it is necessary to consider psychological counseling for patients.
背景与目的:慢性阻塞性肺疾病(COPD)是一种世界性的健康问题,发病率越来越高。它通常与负面的健康结果有关,包括抑郁症。因此,本研究的目的是确定COPD患者抑郁的患病率。材料与方法:本横断面研究采用描述性分析设计,对2018年4月至9月在伊朗哈马丹Shahid Beheshti教学医院肺病科就诊的103例呼吸疾病门诊患者进行研究。纳入标准为根据病史、体格检查和标准肺活量测定方法诊断为重度和极重度COPD。无丧亲之痛、创伤和使用抗抑郁药物的患者被排除在研究之外。采用21项贝克抑郁问卷测量抑郁水平。结果:男性57例(55.3%),女性46例(44.7%)。大多数受试者(33%)年龄在50-59岁之间。结果显示,研究人群中抑郁症的患病率为66%。2575%肺容积时用力呼气流量、1 s用力呼气容积与COPD严重程度有显著相关性(P=0.024, P=0.003)。结论:针对重度及极重度COPD患者抑郁患病率高的情况,有必要考虑对患者进行心理疏导。
