Abstract

Normal 0 false false false EN-GB X-NONE AR-SA MicrosoftInternetExplorer4 Background: Coronary Artery Disease (CAD) is a major cause of death worldwide including Iran.  The risk of developing disease in patients without symptoms is assessed in part by factors that are associated with disease. Among these factors family history points to the significance of genetic component in the risk of CAD. The identification of the genetic variants that confer risk for CAD is essential for detecting high-risk individuals, so preventative life style and therapeutic action can be taken before overt disease develops. So far more than 100 genes have been reported with possible role in developing risk for CAD. Matrix- Gla Protein (MGP) is one of these genes that association of its single nucleotide polymorphism (SNP) with CAD has been reported.  Among the polymorphisms, there are two promoter SNPs at position -7 & -138 that their association with CAD has been reported before. Here we investigated the association of these SNPs with CAD in Iranian population.
Methods: 150 cases and 150 controls were selected on the basis of their clinical assessments and angiographic reports. DNA was extracted from blood samples. The genotypes for both SNPs were determined using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method with size fractionation on Polyacrylamide gel.
Results: The comparison of allele & genotype frequencies between patients and controls showed that there is an excess of A allele at position -7 and T allele at position -138 among patients, although these differences were not significant (p<0.2, and p<0.5 respectively).
Conclusions: This study suggests no association of these SNPs with CAD in Iranian population. Confirmation of this finding needs independent repeat of similar studies.

Normal 0 false false false EN-GB X-NONE AR-SA MicrosoftInternetExplorer4 !mso]> ject classid="clsid:38481807-CA0E-42D2-BF39-B33AF135CC4D" id=ieooui> Background: Duplex Doppler ultrasonography (US) has newly suggested, being an important diagnostic technique in the non-invasive evaluation of hepatic vasculature and some hepatic parenchymal diseases. New findings suggest that diffuse fatty infiltration of liver can alter normal hepatic vein and artery doppler indices. The following study has been performed to evaluate the effect of fatty infiltration on hepatic artery resistance index and hepatic vein waveform patterns.
Methods: Sixty patients with various degrees of fatty infiltration on liver biopsy and twenty normal subjects without any sign of hepatic fat infiltration in ultrasonography examined using standard colour and spectral doppler sonography. The waveforms of Hepatic Vein were classified into three groups: regular triphasic waveform, biphasic waveform without a reverse flow, and monophasic or flat waveform. The hepatic artery resistance index was calculated as the mean of three different measurements.
Results: The mean BMI in Nonalcoholic fatty liver disease group and normal subjects was 26.9(SD=3.3) and 22.4(SD=1.7) Kg/m2, respectively with a range of 22 up to 44 Kg/m2. Abnormal Hepatic Vein waveforms (biphasic and monophasic) were found more frequently in doppler sonography (p<0.001) in patients with Nonalcoholic fatty liver disease (12 biphasic and 17 monophasic) compared to normal subjects. Hepatic artery resistance index was significantly lower in Nonalcoholic fatty liver disease patients [0.7(SD=0.1)] compared to normal ones [0.8(SD=0.0)] (p<0.001).
Conclusions: The incidence of abnormal hepatic vein waveforms is significantly higher in patients with fatty infiltration compared to those who had no abnormality in liver ultrasonography and these patients had a significant lower hepatic artery resistance index. supportFields]> ADDIN EN.CITE  ADDIN EN.CITE.DATA l>

Abstract
Background: Brucellosis is a systemic infection caused by gram-negative coccobacilli and facultative intracellular bacteria of the genus brucella. Brucellosis is a bacterial disease common to humans and livestock. Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. The humoral and cellular immunity plays an important role in brucellosis. The effect of phagocytosis and cellular immunity has been demonstrated in brucellosis. The effect of cupping as a therapeutic method on bacterial diseases has been demonstrated. By considering this fact that cupping is an effective method on host immune system functions and has potential effect to regulate the inflammatory reactions.
Methods: This experimental study was carried out on 48 rats in 6 groups (48 rats were divided into 6 groups) during the first 6 months from January 2015 to July 2016 in the laboratory of microbiology and animal of Hamedan University of Medical Sciences. The rats were infected through the injection of Brucella melitensis with plenty 5×105 (cfu/ml) of bacteria. After a week, in order to approve the accuracy of the infection in the studied rats inoculated with coombos Brucella melitensis, Wright test, 2-Mercaptoethanol test and Coombs' Wright test were used. The rats were then treated with cupping method in their sacral area. IFN-γ was measured using enzyme-linked immunosorbent assay. And the study of tissues using hematoxylin and eosin (H&E) Staining.
Results: The results of this study showed that cupping leads to an increase in the mean serum level of interferon-gamma. The histopathological study of liver tissue showed that the radial arrangement was not observed in the infected group with brucellosis and the cells were acidophilus. While, the radial arrangement was observed in treated rats with cupping, but it was not complete. The number of enlarged sinusoids were reduced. But, cell infiltration was observed.
Conclusion: This study showed that cupping can increase serum level of IFN-γ, and thus help to the clearance of disease and improvement of injury in the brucellosis animals lab.

Abstract
Background: Infective endocarditis occurs due to the presence of microorganisms in the endocardium or the heart valves. Nowadays, infective endocarditis is still a major cause of death with an incidence rate of 5 to 7.9 per 100,000 populations. The aim of the study was to determine antibiotic resistance pattern of bacterial agents isolated from blood culture of patients with infective endocarditis.
Methods: In this retrospective study, infective endocarditis patients who were admitted to Sina and Ekbatan hospitals in Hamadan City, Iran, from March 2005 to February 2014, were enrolled. All demographic data, clinical manifestations, physical examinations and echocardiography reports of the patients were recorded in a check list. For all patients, blood cultures in Mueller Hinton agar and antimicrobial susceptibility testing for ceftriaxone, ceftazidime, oxacillin, cefazolin, vancomycin, imipenem, clindamycin, etc. were done by disk diffusion method. All data analyzed by SPSS statistical software, version 16 (IBM, Armonk, NY, USA).
Results: A total of 61 patients with definitive infective endocarditis were included in the study, 50 of them (82%) were males and 11 patients (18%) were females. The mean age of the patients was 37.45±14.79 (range 17-74) years and 37 (60.7%) of the patients lived in urban areas. The mean duration of admission was 20±13.59 days. In addition, 38 patients (62.3%) were injection drug users (IDUs) and 23 (37.7%) non-IDU. Meanwhile, 54 (88.5%) of them had normal valve endocarditis and 7 cases (11.5%) had a prosthetic valve endocarditis. Moreover, the most common underlying disease in the natural valve endocarditis was rheumatoid fever (6.6%). Blood cultures were positive in 44.3% of the patients. The most common isolated organism was staphylococcus aureus in 15 cases (55.55%), which had the highest resistance to oxacillin. Most patients were managed by antibiotic therapy, but 15 cases (24.6%) underwent cardiac surgery. In follow up patients between 3 months to 9 years, 19.7% of the patients had complete recovery and 8.2% of them died.
Conclusion: According to the findings, antibiotic resistance pattern of bacterial agents isolated from blood culture of patients with infective endocarditis was changed.

Abstract
Background: Otitis is the most common infectious disease of the ear with internal and external cranial complications. If the infection is in the middle ear, it causes otitis media. If the infection is in the external ear, it’s along with otitis externa (OE). Different types of otitis media include acute otitis media (AOM), chronic otitis media (COM) and Otitis media with effusion (OME). This study aimed to investigate the different types of otitis and its symptoms.
Methods: This cross-sectional study was conducted from March 2019 to February 2020 for 200 patients who have been referred to the ENT center of Shafa hospital, Kerman, Iran. Sampling was conducted with ease and no need for specified sampling distribution. The type of otitis was written in a questionnaire by the physician after the examination. The present research investigated types of otitis along with its symptoms. Also, their demographic information was determined.
Results: This study was done among 200 patients. 106(53%) participants were diagnosed with external otitis and the most common symptoms include discharge from the ear, inflammation and pain of the ear. 53 patients (26.5%) had acute otitis media with the most common symptoms of tympanic membrane color change and otalgia. 22 patients (11%) were diagnosed with chronic otitis media. So, perforation of the tympanic membrane and otorrhea were considered as the most common symptoms for these patients. 9(9.5%) of participants had otitis media with effusion that aural fullness and reduction of hearing were the most common signs. In this research, most of the patients were between the age of 11 to 30.57% of patients in this study were men and 43% were women. Most of the patients were between the age of 30-40 and the least number of patients were over the age of 70. Among the 200 patients, most of them lived in cities and provinces rather than villages. 67.5% of patients didn’t have an academic certificate.
Conclusion: Considering the high prevalence of otitis among patients with ENT disorder, it was recommended that otitis should be recognized and cured.

Abstract
Background: Urinary tract infections are among the most common diseases in different communities and occur in all age groups. Failure to diagnose the disease correctly and promptly can cause complications such as damage to the urinary tract and kidney parenchyma, increased blood pressure, uremia. Also, in pregnant female patients It may lead to premature birth and even abortion. Therefore, correct and timely administration of antibiotics is very important in the treatment of patients. This study aimed to compare the results of antibiogram testing of patients with suspected urinary tract infections by both rapid and classical methods.
Methods: This cross-sectional study was performed from the beginning of March to the beginning of September 2019, on patients with urinary tract infection Who had been referred to Sina Hospital of Hamedan, Iran. Urine samples were collected 20 cc from patients. The test was performed directly at the same time with urine culture to determine antibiotic susceptibility. The agreement between the two methods was considered as a huge error, major error and minor error. Finally, the data were statistically analyzed with SPSS software version 16.
Results: 92 patients, 23 men (25%) and 69 women (75%) with a mean age of 53.18±18.49 years were included in the study. Direct testing had a significant agreement with the standard test in 90.8% of the results (P<0.001). 9.2% of the antibiogram tests did not match, of which 0.3% were huge errors, 4.7% were major errors and 4.2% were minor errors. The highest number of microorganisms found were Escherichia coli (n=66), Klebsiella pneumoniae (n=13), Pseudomonas aeruginosa (n=6), Acinetobacter (n=1), Enterococcus (n=2), Alcaligenes (n=1), Streptococcus (n=1), Staphylococcus haemolyticus (n=1) and Moraxella (n=1) respectively. The highest rates of urinary tract infections were with Escherichia coli, third-generation cephalosporin antibiotics, and broad-spectrum antibiotics.
Conclusion: The agreement between the direct and standard antibiogram method was acceptable, and the direct antibiogram method can be cited by doctors in many cases.
