Scientific journals are the most major tools in disseminating research findings. With the increasing number and price of scientific journals, libraries need to select journals. Citation analysis is a practical method in identifying the best titles to be subscribed. This study was to identify core journals in the field of dentistry using citation analysis. Two hundered and seventy six documents including dentistry theses (241 titles) and faculty papers (35 titles) indexed in Science Citation Index (SCIE) were selected and their references were extracted and evaluated using citation analysis methods. The distribution frequency of journals confirmed the Bradford’s Law of Scattering representing core dentistry journals. Eleven thousand twenty three references were totally extracted. Average reference per theses and papers was 39/25 and 44/74, respectively. English journals and books were the most frequent referred documents having 95% of total references approximately. The most updated references were in English dated during 2001-2005 and 2006-2010. Using the Bradford’s Law, five journals were introduced as core dentistry journals. Selecting and subscribing core journals leads into cost-effectiveness in libraries and plays an important role in meeting user’s needs. While having many challenges in accessing scientific resources, core journals selection and subscription is an intelligent action resulting in effective use of financial resources.

One of the most important factors to present successful managers is general health. If managers have not highly general health, then they will encounter many problems. Therefore, this research is aimed to induce the general health among Tehran University of Medical Sciences hospitals’ administrators. A cross-sectional, deceptive and analytical study was conducted among 25 Tehran University of Medical Sciences hospitals administrators in Tehran, Iran. The research tool was general health questionnaire developed by Goldberg and Hillier to assess the administrators general health and its demographic details. Data was analyzed by SPSS software and using analytic statistical methods. The results of this study showed that the hospitals administrators had normal range of general health. Also, there was significant correlation between anxiety with physical dysfunctions, and depression with physical dysfunctions, and anxiety with social functions. The rate of general health among TUMS hospitals administrators is higher than the other mangers compared with similar studies in Iran and out of Iran. Therefore, we suggest periodic medical examination, general health training, and consultant services to develop or maintain the general health among healthcare managers.

Complaint is the expression of dissatisfaction that needs a response and investigation. It is an effective tool to improve the quality of services. The aim of this study was the survey of complaints, factors affecting them, and the complaint process in Firoozgar Hospital. This was a retrospective descriptive study. All registered complaints, such as written, verbal and telephone complaints were reviewed in 2012. The data were extracted from the complaint forms of Firoozgar Hospital, which included several parts: personal information, ward name, person complained of, and explanations about the problem. Then, effective factors in complaints were classified and then analyzed by descriptive statistics. The most frequent complaints were related to nurses (192 cases). Complaints about doctors were 171 cases. Inappropriate communication (23.64%) was at the top of patient complaints; and complaints about fees (14.18%) was the next. Among paraclinical and support units, installations unit had the highest number of complaints (52 cases). Since inappropriate communication was the point being complained of more than any other issue, interventions in this area should be considered. Hospitals should identify the root of problems systematically.

Cream is a rich dairy product with the pH close to neutral and limited preservation capability. Cream is suitable and rich for microbial growth. In the past few decades, there was a great concern in contamination of food products. Salmonella and Yersinia species are two important pathogens causing food poisoning and human gastroenteritis. The aim of the present study is to investigate the quality of traditional cream for bacterial contamination. This is a cross-sectional study. In total, 100 unpasteurized cream samples were collected from 5 regions in Tehran. The Salmonella was enriched in Selenite-F broth, and Yersinia in phosphate buffer in two weeks in cold condition according to CDC, and then were inoculated in MacConky and CIN agar for 24 hours. The suspected colonies were examined for phenotype and their identification was confirmed by API-20 E. In general, 29% of tested cream samples were contaminated with at least one kind of bacteria, 3% with Yersinia (1strain Y.enterocolitica, 1 Y.intermedia, 1 frederiksenii), and 2% with Salmonella paratyphi B. The other bacteria like Escheichia coli, Enteobacter, klebsiella, and Citobacter were also isolated. Five samples were contaminated with two kinds of bacteria. The results of this study indicate that more quality control should be applied on the cream produced in the city of Tehran by health control office for food products.

Healthcare processes have caused many dangers to patients, and the increase of medical errors is one of the most important consequences of such processes. The present research is conducted to reduce medical errors through presenting a model to control them. In this mixed (quantitative-qualitative) research, a conceptual model was assembled. Then using the model and an interview, a questionnaire was made. The interview and the researcher-made questionnaire were used to collect data. The statistical population included the related people and the practitioners involved in medical errors in Tehran University of medical Sciences (TUMS) hospitals. The sample consisted of 252 employees who were non-randomly selected from those hospitals. Once the affecting factors were determined, the data were analyzed through factor analysis technique. The gathered data were analyzed using descriptive and inferential statistics. Finally, the research model was presented. The selected individuals pointed out 9 factors controlling the medical errors: culture, factors associated with patients, factors related to providers, factors associated with errors, structural factors, role of disclosure, error registration, individual factors related to reporting, and organizational factors related to reporting. The 9 factors are the subdivisions of three main factors which account for 57/46% of the total variance of data. The most decisive power is related to disclosure 0.737 and the least (0.053) pertains to structure. Discloser of medical errors and their registration are factors which are effective and essential in controlling medical errors in TUMS hospitals.

The applicability of any technology to enter a certain field is determined by defining the advantages and disadvantages of the system in that field. The aim of this study is to show the advantages and limitations of using speech recognition systems in health care and providing practical solutions to improve the acceptability of the system in that field. This is a descriptive research with a review method that employs library resources and online databases such as Proquest, Pubmed, Science Direct, Ovid and Scientific Information databases using key words like speech recognition software, health care, benefits, barriers, and solutions. Speech recognition system has many advantages like increased accuracy of medical documentation, and reduced documentation time. It is a tool for data entry into electronic health records. However, there are several limitations in applying the system in Iran, such as the lack of definition of database system and the high cost of hardware and software. Considering the study results in relation to the benefits and limitations of systems in healthcare area, solutions such as production of a national integrated database for the exchange of health information, improving database to increase the accuracy of word recognition, and training the users of the system can reduce the limitations of the system to some extent. Also, in the country’s movement towards the implementation of electronic health records and the users’ need to enter data into the computer, the software is a good alternative to keyboard and mouse input.

Isoflurane is one of the selective and mostly-used respiratory anesthetic materials in the field of neurosurgery. Studies have shown that temporary rise in the level of liver enzymes may occur after anesthesia by halogenic ethers and hence cause liver lesions. The aim of this study was to investigate the effects of isoflurane on the activity of ALT-AST-ALP-GGT enzymes as an indicator of liver function. This study was performed on a sample of 40 patients who were under neurosurgery without any liver disease in Milad Hospital of Tehran. The patient's blood samples were collected before, 24, and 72 hours after anesthesia. The enzymes activities was assessed by spectrophotometric method. Insignificant changes before and after anesthesia were seen in the activity of ALP, and AST enzymes. The level of ALT enzyme has a significant rise, 72 (P=0/022) and 24 (P=0/014) hours after anesthesia in comparison with before anesthesia. The level of GGT enzyme in comparison to its past has significant rise 72 hours after anesthesia (P=0/002). The level of this enzyme showed a significant difference 24, and 72 hours after anesthesia (P=0/041). The significant changes seen in the levels of ALT, GGT enzymes in three different periods of time might be as a result of possible liver parenchymal and cholestatic damage caused by using Isoflurane or other drugs such as Midazolam which effects liver function. It seems the assessment of the levels of these enzymes can provide useful information for probable subsequent actions.

Managers are always looking for better ways to improve productivity of staff. The aim of this study was to introduce a model based on work and time measurement for Staff Management based on performance in hospital. This descriptive - practical study was conducted in ten steps for a medical documents expert’s in a general hospital. The main activities of employees were determined via interview and direct observation. Then expected time, tolerances, final coefficient and work units for each activity were calculated. Finally, the total working units were calculated. Implementation of introduced model for a medical documents expert’s in a general hospital showed that the total work units which the staff was obliged to do in one month was 918 units and the remaining (1160-918) was the extra units. Using appropriate models for the performance management of hospital staff workloads, can help to improve the hospital productivity and staff satisfaction.
