Abstract Background and objectives: Ureaplasma urealyticum is one of the most important causes of Nongonococcal urethritis (NGU) and non-specific urethritis (NSU) in men. Also Mycoplasma hominis has a role in causing NGU and NSU. The aim of this study was the detection of Mycoplasma hominis & Ureaplasma urealyticum in men suffering from NGU and NSU by prostatic massage method and first- void Urine samples. Material and Methods: Urethral secretion samples, taken after prostatic massage and first-void urine, of 75 patients referred to department of bacteriology of Tehran University of Medical Sciences were examined for ureaplasma and mycoplasma by culture method in 2004-2005 Results: In prostatic samples, 19 and 11 samples are positive for ureaplasma and Mycoplasma, retrospectively. In first-void urine samples, 17 and 9 samples are positive for ureaplasma and Mycoplasma, retrospectively. Conclusion: The results show that if it is impossible to obtain urethral sample via prostatic massage , we can use first- void urine instead. Key words:Mycoplasma hominis, Ureaplasma urealyticum,Nongonococcal urethritis, Nonspecific urethritis, prostatic massage, first voided Urine

Abstract: Background and Objective: A wide variety of opportunistic pathogens has been detected in hospital surfaces. Among these , Pseudomonas species are one of the leading causes of nosocomial infections, frequently found in hospital environments. The purpose of this study was identification of antimicrobial susceptibility of Pseudomonas spp. isolated from different Section of ShahidRajaeii hospital, Tonekabon. Material and Methods: the samples (460) from different sections of Shahid Rajaeii hospital, Tonekabon were collected between December 2010 and June 2011. The identification of the strains was performed by using biochemical tests and API20NE (Biomerieux) ,and antimicrobial susceptibility of the isolates against different antibiotics was determined by disc diffusion test. Results: of 460, 61(%13/26) strains of Pseudomonas are isolated from all the sources. The highest rate of Pseudomonas spp. is recorded in Surgery and ICU, while the lowest in Dialysis ward. Of 61 strains of Pseudomonas, 52 (85/25%) are belonged to Pseudomonas aeruginosa, six (9/83%) to Pseudomonas stutzeri, two (3/28%) to Pseudomonas putida and one (1/64%) to Pseudomonas fluorescens. Conclusion: the environments of the hospital can be the vehicles of Pseudomonas spp. therefore, both the patients and personnel should have extra attention to their personal hygiene to avoid Pseudomonas infection.

Abstract Background and Objective: This study was aimed to determine the extent of bacterial contamination and drug resistance patterns of isolates colonized in colonoscope and endoscope and in relevant personnel. Material and Methods: A total of 107 samples were obtained from staff of endoscopy and colonoscopy units (SEU and SCU) and gastroenterological imaging equipment. For isolation and identification of the bacteria, swab culture method and biochemical identification test were used, respectively. Antimicrobial resistance profiles, multi-drug resistance (MDR) patterns and phenetic relatedness of these isolates were also analyzed according to standard methods. Results: Most frequent pathogenic bacteria among the SEU and gastroenterological imaging related equipments were included S. aureus (20.8 % and 0 %) Enterococcus spp. (0 % and 5.4%) Pseudomonas spp. (0% and 13.5 %), and Clostridium difficile (0% and 12.5%). Analysis of resistance phenotypes showed a high frequency of MDR phenotypes among the SEU (82.1%), and also in endoscopes, colonoscopes, and other equipments (20%, 50% and 100%, respectively). Phylotyping of S. epidermidis isolates showed the role of staff in transmission of resistance strains to medical equipments and also circulation of strains with identical resistance phenotype among the studied samples. Conclusion: High frequency of pathogenic bacteria in colonoscopes, endoscopes and in the staff of endoscopy & colonoscopy units, and also contamination of these instruments with MDR pathogens emphasize the need for proper disinfection of endoscopes and colonoscopes and also instruction of staff in these units. Key words: Bacterial Contamination Endoscope Colonoscope Antimicrobial Resistance Gastrointestinal Disease.

Abstract Background and Objective: Bacterial colonization in upper respiratory airways is one of the major risk factors for the development of the ventilator–associated pneumonia (VAP), which is the most common and serious hospital-acquired infection in intensive care unit (ICU). The aim of this study was to determine the frequency of oropharyngeal microorganisms of patients with tracheal tube hospitalized in ICU. Material and Methods: Of 39 patients hospitalized in ICU of panje Azar Hospital, the oropharyngeal cultures were taken after admission. The samples were evaluated for growth of Staphylococcus aureus, Pneumococcus, Enterococcus, Pseudomonas, and E-coli. Results: The mean age of the patients (21 men, 18 women) was 43.64±15.01. The culture was positive in 28.2% and the most common isolate was Pseudomonas aeruginosa (10.3%). Conclusion: Pseudomonas, which is the main pathogen for ventilator- associated pneumonia, may be a potential threat for the patients hospitalized in intensive care units.

             Background and objectives: Matrix metalloproteinase-13 (MMP-13) and activin receptor-like kinase 5 (ALK5) are considered as important factors contributing to knee osteoarthritis (OA) pathogenesis. Here, we compared therapeutic effects of mesenchymal stem cells (MSCs), ozone and exercise training alone and combined on expression of MMP-13 and ALK5 in rats with knee OA.
            Methods: Knee OA was induced by a surgical method. Rats with OA were then randomly divided into several groups, including model, MSCs, ozone, exercise, MSCs + ozone, MSCs + exercise, ozone + exercise and MSCs + ozone + exercise groups. Expression of MMP-13 and ALK5 genes was evaluated using RT-PCR. Data were analyzed using SPSS software at significance of 0.05. 
            Results: Expression of MMP-13 and ALK5 differed significantly between the study groups (P<0.0001). Knee OA was significantly associated with overexpression of MMP-13 and ALK5 in the cartilage tissue of rats with knee OA. Combined therapy with MSCs, ozone and exercise significantly decreased the expression of MMP-13 and ALK5 in the cartilage of rats with OA (P<0.001). Although MSCs, ozone and exercise training were effective to mitigate expression of MMP-13 and ALK5 genes, ozone therapy was more effective compared to the other two therapies.
            Conclusion: Although ozone, MSCs and exercise training alone could decrease the expression of MMP-13 and ALK5 genes, combined therapy with MSC, ozone and exercise is more effective.  
            Keywords: Osteoarthritis, O3, MSCs, exercise, MMP-13, ALK5.

Objectives: Although extrapulmonary tuberculosis (EPTB) is a secondary target for national TB control programs, its significance has increased worldwide. In order to study the epidemiology of EPTB in the Northeast of Iran, this survey was conducted.
Methods and Methods: A population-based, retrospective analysis of all cases of EPTB during 2012–2015 reported to the TB Unit of the Golestan was performed. Socioeconomic and environmental variables, sites, admission, mode of diagnosis and outcome status were collected. Data analyzed through SPSS 25.0 by descriptive and analytical statistical methods.
Results: A total of 741 cases of EPTB were included. Patients were mainly female (59.1%), age of 0 to 40 years old (57.6%), less than five years of education (46.7%) and mainly Fars (39.6%). Non-native ethnicities significantly acquired EPTB more than native ethnicities (p<0.001). Mortality rate was 5.1%. Smoking detected more frequently in EPTB patients (p<0.001). HIV status of most EPTB patients (89.3%) were unknown. The most common forms were pleural (30.5%) and lymphadenopathy (22.0%). Cultures and PCR performed in only about 10 percent of EPTB patients in our study.
Conclusions: EPTB was more prevalent in non-native population. Improvement of socioeconomic conditions and screening program may be successful in reducing the problem among immigrant
