Postoperative pain following total hip arthroplasty (THA) impacts patients' rehabilitation and quality of life. Although gabapentin has been widely used for pain control, its effectiveness in hip arthroplasty is not well established. The aim of our systematic review is to evaluate the effect of gabapentin on postoperative pain after THA.

A systematic search was conducted in three databases: MEDLINE, PsycINFO, and Embase, through OVID, using the keywords gabapentin, pain, and hip arthroplasty, with no restrictions on language or publication date. To evaluate the quality of the articles, the Cochrane Collaboration tool was used.

Five studies, including 728 patients, were included in our systematic review. Gabapentin 600 mg was used in three and 1200 mg in two studies. The results of these studies showed that gabapentin had no significant effect on pain or morphine consumption after THA. Besides, gabapentin use was associated with side effects such as rash, nausea, headache, vomiting, and pruritus.

Gabapentin does not decrease pain or morphine consumption after THA. However, future studies with a larger sample size and longer follow-up period are required.

Tourism will soon become the largest service industry in the world with the help of IT. Social networking platforms, which have become prevalent via mobile data, are valuable tools that contribute to the information and telecommunication technology (ICT). These platforms, which provide interactions and exchanges of various contents among the users, have developed new lifestyles and behavioral models among the tourists. Marketers must enjoy the online social networks and e-tourism to increase their competitiveness, market share, and the generated profit by providing the tourists with some services tailored to their demands. Upon reviewing 100 relevant qualitative and quantitative studies, we used an interpretive structural modeling (ISM) approach to present a model with five primary themes, in order of priority: a major environment, managerial factors, individual factors, group factors, and marketing factors. Through these factors, social networks affected tourists’ behaviors. The model was then tested on Iranian tourists’ behaviors using qualitative and quantitative statistical methods. Results could be used by virtually all marketers and activists in the tourism industry.
 

Using the tools such as information and communication technology is essential for the growth of the tourism industry, and it is not possible for this the industry to operate and survive in a competitive market without the effective use of such tools. As one of the most effective tools for marketing and influencing the tourists’ behavior, virtual social networks can ensure an appropriate share of the tourism market as well as other benefits such as economic, cultural, employment, sustainable development, and so on in case of effective use and correct response to the tourists’ demands. The present research aimed to identify and formulate a comprehensive model of the main factors by which, social networks affect the tourists’ behavior in decision making, selection and purchase of tourism services. For this purpose, after reviewing about one hundred related researches with qualitative and published results in valid journals, at first the main components by which, social networks affect the tourists’ behavior were identified among 400 initial approved sources and interviewing the experts and using Meta Synthesis method and extraction of 1400 open and 45 content codes, and then, the final model was developed for leveling the variables using structural-interpretive modeling. The final research model consists of five main themes or variables in three levels by priority and influence including macro environment (level three), marketing (level two) and management, individual, group factors (level one) which can be used by all tourism activists to improve marketing, value creation and profit making processes.

Weaver-Dunn technique is one the prevalent methods for treating acute acromioclavicular joint (ACJ) dislocation. Until now, several modifications of this technique have been introduced. Regarding the drawbacks of the previous modifications and the importance of presence of an intact coracoacromial ligament (CAL), we introduced a new modification of Weaver-Dunn technique and investigated the preliminary results.
There were 15 patients with acute ACJ enrolled in current study. In the modified surgical technique, the medial half of the CAL is dissected from the bone and passed through a hole made in the clavicle bone and tied on itself. Before the operation and at the last visit, CC distance was measured on both sides. At the last visit, Constant score and UCLA score were completed. The pain intensity was measured using visual analogue scale (VAS). The patients were followed for 4.2±2.6 years.
Preoperatively, CC distance of injured side was significantly greater than the other side (19.5±1.6 mm Vs 7.1±0.5 mm; p Treatment of acute ACJ dislocations using the modified technique was associated with favorable outcomes. Utilizing this method, the joint stability and function are preserved.

The role of a mobile-bearing knee arthroplasty is still not clear. This study was designed to compare the mobile and fixed-bearing prosthesis.

In 30 knees a fixed-bearing and in 38 knees a mobile-bearing prosthesis was used. The results were compared using the "Knee Society Scoring System".

The mobile-bearing group of patients had an average age of 65 and 34 months average follow-up. The fixed-bearing group had an average age of 69 years and a mean follow-up of 30 months. The average knee score functional score and overall score in the mobile-bearing group rose from 29 45 73 to 64 67 128; and in the fixed-bearing group from 31.7 34 65.9 to 68 57 125 prospectively. The difference between two groups was not significant statistically.

Although in both groups the average knee scores increased after the operation there were however no significant difference between knee scores in the two types in short-term and no preference between two types of prosthesis.

In recent decades there has been a boom in medical publication all across the world. There are numerous medical journals whose articles tend to form the basis of the art and science of medicine. Along with this widespread upward trend ethics of conducting and publishing medical research have undergone natural evolution. This article intends to review some of the existing publication related to the standards of medical and scientific research and publishing articles in medical journals. Paying meticulous attention to these standards guarantees credibility and originality of medical articles and the publishing journals.
