Abstract
Background: Rotator cuff injuries are one of the most common causes of shoulder pain.
There are different therapeutic approaches in this disease. The evidence of the positive effect of exercise therapy in this pathology is inconclusive. This study aimed to investigate the effect of a complete exercise protocol on improvement of the patients with rotator cuff injuries.
Methods: The patients with shoulder pain received the 12-week exercise protocol in 4 phases if they had confirmed rotator cuff injuries in clinical examination and shoulder MRI.
Pain was measured by visual analog scale (VAS) and function was measured by two questionnaires; disabilities of the arm, shoulder and hand (DASH) and western Ontario rotator cuff index (WORC). Range of shoulder joint motion (ROM) was measured in five directions by goniometry. All of the outcomes were evaluated before intervention and in 6, 12, 24 weeks after starting the intervention.
Ethic: This study was registered in Iranian Registry of Clinical Trials (IRCT20100718004409N13). A written consent was taken from All participants before the study.
Results: In this study Twenty-four patients with rotator cuff tendinopathy and tear were analyzed finally in terms of effectiveness of exercise therapy. The average of their age was 51.7 years old. 14 patients (53.8%) with Supraspinatus tendinopathy, 6 patients (23%) with Supraspinatus tear, 3 patients (12.5%) with Supraspinatus plus biceps tendinopathy, and one patient (4.16%) with Subscapularis plus Biceps tendinopathy were assessed. The pain score (Visual Analog Scale) decreased at all fallow-ups specially after 24 weeks (3±0.1) versus before intervention (8±0.1) (P value < 0.001). Shoulder range of motions by goniometer and also the patients function based on WORC and DASH Questionnaires were improved after 24 weeks versus before intervention that was significant statistically and clinically (P value < 0.001).
Conclusion: A 12- week exercise protocol including strengthening, stretching, PNF and dynamic stabilizer exercises was effective on pain reduction and improvement of function and shoulder joint range of motion improvement in the patients with shoulder rotator cuff tendinopathy and partial tear. The improvement of the variables lasted 6 months.

Abstract
Background and Aim: Different implant angulation, which is unavoidable in clinical situations, can affect the accuracy of impression. The aim of this study was to investigate the effect of fixture position on the accuracy of connecting impression coping to implants with internal hex.
Materials and Methods: A gypsum model with 4 implants with internal hex connection was prepared. The implants were installed in different mesiodistal angles of 0, 15, 25 and 35 degrees to the longitudinal axis in the gypsum model. To simulate the gums, a gingival mask was injected around the implants to a height of 2 mm. After a training session for senior dental students on how to close the impression coping, forty students were asked to close the impression copings on four implants. The correctness of the impression coping was evaluated by an expert prosthodontist. Data were statistically analyzed using Cochran Q test. Significance level was considered 0.05.
Ethical Considerations: this article is approved by ethics committee of Arak University of Medical Sciences.
Findings: The correct performance of students in connecting the impression coping to the implant at angles of 0, 15, 25 and 35 degrees was equal to 85%, 72%, 52%, 35%, respectively. With the exception of 0 and 15 degree groups, a statistically significant difference was observed between different study groups.
Conclusion: The fixture position has a significant effect on the accuracy of connecting impression coping to the implants with the internal hex and by increasing the implant angulation, the accurate connection the impression coping to the implant decreases.

Abstract
Background: and Aim Acinetobacter baumannii causes various nosocomial infections and has a high antibiotic resistance. Probiotics can produce metabolites with antimicrobial properties. This study aims to evaluate the antimicrobial ability of probiotics against nosocomial pathogens by inhibiting the ompA gene expression effective in biofilm formation in Acinetobacter baumannii.
Methods & Materials: The antimicrobial properties of probiotics against nosocomial pathogens were evaluated phenotypically. The polymerase chain reaction (PCR) technique was used to identify the ompA gene in Acinetobacter baumannii. After treatment with Bacillus licheniformis supernatant, the ompA gene expression was compared before and after treatment with real-time PCR technique.
Ethical Considerations This study was approved by the ethics committee of Islamic Azad University, Qom branch (Code: IR.IAU.QOM.REC.1398.004).
Results: Among the study probiotics, Bacillus licheniformis supernatant had the best antimicrobial properties against nosocomial isolates of Acinetobacter baumannii A52, Acinetobacter baumannii ATCC19606, Kelebsiella pneumonia ATCC70063, and Pseudomonas aeruginosa PAO1. Bacillus licheniformis supernatant also significantly reduced the biofilm formation and ompA gene expression in Acinetobacter baumannii.
Conclusion: Bacillus licheniformis can produce substances with antimicrobial and antibiofilm properties. It can be used for controlling the causative agents of nosocomial infections.

Abstract
Background and Aim This study aimed to investigate the clinical and laboratory characteristics of hydatid cyst disease in patients admitted to Imam Reza, Imam Hossein, and Bisotoon hospitals in Kermanshah City, Iran, from 2014 to 2018.
Methods & Materials In this descriptive study, we studied and analyzed the medical records of 350 patients with hydatid cysts who were hospitalized and underwent surgical treatment in Kermanshah hospitals from 2014 to 2018. Also, the demographic characteristics of patients, including gender, age, occupation, place of residence, and affected organs, were extracted and recorded.
Ethical Considerations The Ethics Committee of Kermanshah University of Medical Sciences approved this study (Code: IR.KUMS.REC.1398.366).
Results In total, 350 patients with a Mean±SD age of 43.2±19.7 in women and 43.3±20.7 in men were admitted with a diagnosis of hydatid cyst. The highest and lowest prevalence of hydatid cysts were in the age groups of 41-50 (16.5%) years and 1-10 (4.8%) years, respectively. The prevalence was 181 (51.7%) in women and 169 (48.2%) in men. The organs mostly infected with hydatid cysts were the liver, lung, and brain, with 241 cases (68.8%), 55 (15.7%), and 24 (6.8%), respectively.
Conclusion This study shows that hydatid cyst disease is an important disease, especially in rural areas of Kermanshah Province, Iran.
