      Objective: In our study we wanted to showed the safety, feasibility, efficacy and way how to solve the problems of endovascular repair for aortic dissection with insufficient proximal Landing Zone. Methods: The clinical data of all the patients with insufficient proximal Landing Zone (PLZ) for endovascular repair for aortic aneurism and dissection Stanford type B for the period from October 2013 to June 2014 was prospectively reviewed. According to the classification proposed by Mitchell et al, aortic Zone 0 was involved in 3 cases, Zone 1 in 1 case, Zone 2 in 9 cases and Zone 3 in 6 cases (19 patients in total). A hybrid surgical procedure of supraortic debranching and revascularization, with direct anastomosed truncus brachiocephalicus and left common carotid artery, were performed to obtain an adequate aortic PLZ. Revascularization of the left subclavian artery was carried out on the patient with dissection Stanford type B and short PLZ 2. Results: There was no significant difference of risk factors between Zone 0, Zone 1, and Zone 2 (Table1.), but the length of the PLZ significantly differed between groups (p

      Introduction: Ischaemic, traumatic or neoplasmic damage to the optic chiasm, optic tract or lateral geniculate nucleus affects the retinal ganglion cell (RGC) axons, detected as reduced retinal nerve fiber layer (RNFL) thickness around the optic nerve head. We report a case of vision loss and reduced RNFL thickness after internal carotid artery (ICA) occlusion and middle cerebral artery (MCA) infarction. Case report: A 33-year-old woman with a 3-month history of vision loss in right eye and left hemiplegia. The best corrected visual acuity was 1.0 in left eye and there was no light perception in the right eye. Ocular motility, intra-ocular pressure, anterior segments were normal in the both eyes. Her fundus examinations were normal except optic atrophy in the right eye. Visual field test was not performed because of cooperation difficulties. Magnetic resonance imaging (MRI) revealed an infarction of the right MCA. Computed tomographic angiography showed right ICA occlusion. Optical coherence tomography (OCT) demonstrated 6 clock hours of RNFL thinning in the right eye. Average RNFL thickness of the right and left eyes were 53μm, 96 μm respectively. Conclusions: Our findings show that a relatively short period of ICA occlusion and MCA infarction can cause vision loss and thinning of the RNFL.

      Introduction: The muscle atrophy is one of the most important and frequent problems observed in patients in Intensive Care Units. The term describes the disorder in the structure and in the function of the muscle while incidence rates range from 25-90 % in patients with prolonged hospitalization. Purpose: This is a review containing all data related to the issue of muscle atrophy and is especially referred to its causes and risk factors. The importance of early diagnosis and early mobilization are also highlighted in the study. Material and methods: a literature review was performed on valid databases such as Scopus, PubMed, Cinhal for the period 2000-2013 in English language. The following keywords were used: loss of muscle mass, ICU patients, immobilization, bed rest. Results: From the review is concluded that bed rest and immobilization in order to reduce total energy costs, are the main causes for the appearance of the problem. The results of the reduction of the muscle mass mainly affect the musculoskeletal, cardiovascular and respiratory system. The administration of the cortisone, the immobility, the sepsis and hyperglycemia are included in the risk factors. The prevention is the primary therapeutic agent and this is achieved due to the early mobilization of the patients, the use of neuromuscular electrical stimulation and the avoidance of exposure to risk factors. Conclusions: The prevention of muscle atrophy is a primary goal of treatment for the patients in the ICU, because it reduces the incidence of the disease, reduces the time spent in ICU and finally improves the quality of patients’ life.

      Introduction: Given the large volume of data generated in hospitals, in order to efficiently management them; using hospital information system (HIS) is critical. User participation is one of the major factors in the success of HIS that in turn leads Information needs and processes to be correctly predicted and also their commitment to the development of HIS to be augmented. The purpose of this study is to investigate the participation rate of users in different stages of HIS development as well as to identify the factors affecting it. Method and materials: This is a descriptive–cross sectional study which was inducted in 2014.The study population consists of 140 HIS users (from different types of job including physicians, nurses, laboratory, radiology and HIM staffs) from Teaching Hospitals Affiliated to Urmia University of Medical Sciences. Data were collected using a self-structured questionnaire which was estimated as both reliable and valid.The data were analyzed by SPSS software descriptive statistics and analytical statistics (t-test and chi-square). Results: The highest participation rate of users in the four-stage development of the HIS was related to the implementation phase (2.88) and the lowest participation rate was related to analysis (1.23).The test results showed that the rate of user participation was not satisfactory in none of the stages of development (P< 0.05).The most important factors in increasing user participation include established teamwork from end-users and the support of top managers from HIS development. Conclusion: According to the results obtained from the study, it seems that health care administrators must have a detailed plan for user participation prior to the development and purchase of HIS so that they identify the real needs as well as increase their commitment and motivations to develop, maintain and upgrade the system, and in this way, the success of the system will be assured.

      The real-time ECG signal processing system based on mobile phones is very effective in identifying continuous ambulatory patients. It could monitor cardiovascular patients in their daily life and warns them in case of cardiac arrhythmia. An ECG signal of a patient is processed by a mobile phone with this proposed algorithm. An IIR low-pass filter is used to remove the noise and it has the 55 Hz cutoff frequency and order 3. The obtained SNR showed a desirable noise removal and it helps physicians in their diagnosis. In this paper, Hilbert transform was used and the R peaks are important component to differ normal beats from abnormal ones. The results of sensitivity and positive predictivity of algorithm are 96.97% and 95.63% respectively. If an arrhythmia occurred, 4 seconds of this signal is displayed on the mobile phone then it will be sent to a remote medical center by TCP/IP protocol.

      Introduction: Awareness of the latest scientific research and publishing articles in top journals is one of the major concerns of health researchers. In this study, we first introduced top journals of obstetrics and gynecology field based on their Impact Factor (IF), Eigenfactor Score (ES) and SCImago Journal Rank (SJR) indicator indexed in Scopus databases and then the scientometric features of longitudinal changes of SJR in this field were presented. Method and material: In our analytical and bibiliometric study, we included all the journals of obstetrics and gynecology field which were indexed by Scopus from 1999 to 2013. The scientometric features in Scopus were derived from SCImago Institute and IF and ES were obtained from Journal Citation Report through the Institute for Scientific Information. Generalized Estimating Equation was used to assess the scientometric features affecting SJR. Result: From 256 journals reviewed, 54.2% and 41.8% were indexed in the Pubmed and the Web of Sciences, respectively. Human Reproduction Update based on the IF (5.924±2.542) and SJR (2.682±1.185), and American Journal of obstetrics and gynecology based on the ES (0.05685±0.00633) obtained the first rank among the other journals. Time, Index in Pubmed, H_index, Citable per Document, Cites per Document, and IF affected changes of SJR in the period of study. Discussion: Our study showed a significant association between SJR and scientometric features in obstetrics and gynecology journals. According to this relationship, SJR may be an appropriate index for assessing journal quality.

      Introduction: Pedobarography as a new diagnostic tool enables measuring the pressure between the foot and the floor during dynamic loading. Dynamic analysis of the foot shows advantage over static analysis due to its capabilities for detecting high load points in certain diseases and in certain phases of walking. Pedobarography as a new method in the context of rehabilitation include wide range of clinical entities. Goal: To show the advantages of pedobarography as new diagnostic and rehabilitation method in prevention programs. Material and methods: A prospective study included 100 patients with diabetes mellitus type 2. Research was conducted in the Primary Health Care Center of the Sarajevo Canton and the Center for Physical Medicine and Rehabilitation. The test parameters were: Test of balance–symmetric load for the test, the number of comorbidity, clinical examination of foot deformity, test with 10 g monofilament, HbA1c. From the total sample 45 patients (Group I) were selected, aged 50-65 years, which underwent pedobarography (on the appliance Novel Inc., Munich with EMEDTM platform) and robotic fabrication of individual orthopedic insoles, followed by control pedobarography. Plantar pressure was determined using standard pedobarography, computer recorded parameters: peak pressure (kPa), force (Ns), area (cm). Results: The average age of the respondents was 59.4±11.38 years; altered results on the balance test were present in 34% of patients; 61% of respondents have ≤2 comorbidity. In the total sample, the average number of foot deformity was 2.84. Flat feet have 66% of respondents, and valgus position 57%. The average HbA1c values were 7.783±1.58% (min.5–max.15.0). All subjects (45) after the first, and after the second measurement of peak pressure, have values above 200 kPa, or are in the designated zone of peak pressure that needs to be corrected. In a study was determined the correlation between the number of deformities and peak pressure, the number of deformities and the area upon which plantar pressure act, test with 10g monofilament and peak pressure. Conclusion: Within the framework of prevention programs early diagnosis, detection of sensitivity disorders, adequate treatment and taking load from the feet with the help of pedobarography, are of great importance for the patient suffering from diabetes

      Aim: To evaluate the effect of laparoscopic treatment of unilateral ovarian endometrioma on ovarian reserve using ultrasonographic markers, ovarian volume and antral follicle count (AFC), and two biochemical markers, serum levels of Follicle-stimulating hormone (FSH) and Estradiol (E2). Material and methods: This prospective study included 40 patients in their reproductive age, between 18 and 40 years old. They were treated laparoscopically for unilateral ovarian endometrioma. Markers of ovarian reserve were investigated before and three months after surgery. Transvaginal ultrasound examination was used for measurement of ovarian volume and AFC. Biochemical markers (FSH and E2 levels) were determined by chemiluminescent tests. Results: Ovarian volume was significantly reduced after surgery. There was significant increase of AFC and non-significant increase of E2 levels in treated patients after three months. Conclusions: Laparoscopic cystectomy of unilateral ovarian endometrioma decreased ovarian reserve immediately after surgery with decrease of ovarian volume. But ovarian reserve was increased after three months with increase of AFC and estradiol levels.

      Objective: According to the ‘‘vascular’’ theory, arterial overflow in the superior hemorrhoidal arteries would lead to dilatation of the hemorrhoidal venous plexus. Hemorrhoid laser procedure (LHP) is a new laser procedure for outpatient treatment of hemorrhoids in which hemorrhoidal arterial flow feeding the hemorrhoidal plexus is stopped by laser coagulation. Aim: Our aim was to compare the hemorrhoid laser procedure with open surgical procedure for outpatient treatment of symptomatic hemorrhoids. Material and method: A comparison trial between hemorrhoid laser procedure or open surgical hemorrhoidectomy was made. This study was conducted at Aloka hospital in Kosovo. Patients with symptomatic grade III or grade IV hemorrhoids with minimal or complete mucosal prolapse were eligible for the study: 20 patients treated with the laser hemorrhoidoplasty, and 20 patients–with open surgery hemorrhoidectomy. Operative time and postoperative pain with visual analog scale, were evaluated. Results: A total number of 40 patients (23 men and 17 women, mean age, 46 years) entered the trial. Significant differences between laser hemorrhoidoplasty and open surgical procedure were observed in operative time and early postoperative pain. There was a statistically significant difference between the two groups regarding the early postoperative period: 1 week, 2 weeks, 3 weeks and 1 month after respective procedure (p

      Introduction: Metabolic Syndrome (MetS) is basically a cluster of cardiovascular risks that involve changes in metabolic and hemodynamic indicators; various organizations have defined it with small differences. Metabolic syndrome is a lethal endocrinopathy starting with insulin resistance and inviting a chain of systemic disorders such as abdominal obesity, glucose intolerance or diabetes mellitus (DM), dyslipidemia, hypertension (HT) and coronary artery disease (CAD). Material and methods: This prospective and descriptive study was conducted at the Cardiology Clinic of a Private Hospital in Osmaniye between January 2014 and May 2014. The study population included all patients who were administered a CA procedure at the Cardiology Clinic of Private New Life Hospital in Osmaniye in 2014. Results: The majority of the patients were male (63.3%), the mean age was 59.09±10.98, vast majority of them had social security (98.5%), 32.8% of them smoked, 7.2% had peripheral arterial disease (PAD), 52.5% were diagnosed with DM, 24.8% with HT, percutaneous transluminal coronary angioplasty (PTCA) or stent was administered to 40.3% of the patients who underwent CA and coronary artery bypass grafting (CABG) was decided for 15.5% of them. 41.8% of the patients met the MetS diagnosis criteria. The mean BMI was found to be 28.61±4.68, the mean FBS to be 143.20±74.83, the mean triglyceride value to be 168.73±96.94 and the mean HDL value to be 37.04±9.20. Although male gender came first among the patients who underwent CA, the prevalence of MetS did not show a statistically significant correlation with gender, mean age or smoking. The prevalence of HT, PAD and DM was significantly higher in the patients who met the MetS criteria. The mean values of FBS, HDL, CK-MB, triglyceride and cholesterol were also significantly higher in the patients who met the MetS criteria. As BMI increased, the rate at which MetS criteria are met also increased. Conclusion: The objective is to prevent diabetes and cardiovascular diseases. Weight loss achieved with proper nutrition and an exercise program will have a reversing effect on all the disorders seen in metabolic syndrome.

      Technological diseases are diseases of the modern era. Some are caused by occupational exposures, and are marked with direct professional relation, or the action of harmful effects in the workplace. Due to the increasing incidence of these diseases on specific workplaces which may be caused by one or more causal factors present in the workplace today, these diseases are considered as professional diseases. Severity of technological disease usually responds to the level and duration of exposure, and usually occurs after many years of exposure to harmful factor. Technological diseases occur due to excessive work at the computer, or excessive use of keyboards and computer mice, especially the non-ergonomic ones. This paper deals with the diseases of the neck, shoulder, elbow and wrist (cervical radiculopathy, mouse shoulder and carpal tunnel syndrome), as is currently the most common diseases of technology in our country and abroad. These three diseases can be caused by long-term load and physical effort, and are tied to specific occupations, such as occupations associated with prolonged sitting, working at the computer and work related to the fixed telephone communication, as well as certain types of sports (tennis, golf and others).

      Kunal S. Patel, Narayan Kulkarni, Varun Pratap Singh, Kartik Parikh.
      Background: Cephalometrically the position of maxilla is usually assessed by point A, which is one of the most common cephalometric landmarks used for spatial analysis of maxilla, however in certain scenarios we require a alternative landmark. Aims: In this study a nearest alternative maxillary apical base landmark was identified for Point A substitutions given by different authors. Methods and Material: A cross sectional study was conducted on thirty (30) good quality lateral cephalograms. Only those lateral cephalograms were selected where Point A was easily identified. Landmarks: Sella (S), Nasion (N), Point A and three substitution points Y, L, X were traced. Angles formed by SN with Point A (Angle SNA) and three substitution points (Angle SNY, SNX, SNL) were measured. Correlation of angle SNA with angles SNY, SNX and SNL were derived. Statistical analysis used: Results: Mean and standard deviation for Angles SNA, SNY, SNL and SNX were calculated individually for males and females. ‘T’ Test was applied to determine statistical significance for all the parameters i.e Age, Angles SNA, SNY, SNL and SNX respectively. Karl Pearson correlation coefficient was carried out to determine the statistical significant correlation for Angle SNA with SNY, SNL and SNX. Results: A mean value of 82.80 ±1.90, 83.10 ±1.80, 78.30 ±2.90 and 78.70 ±2.70 for Angle’s SNA, SNY, SNL and SNX respectively was observed. A statistically significant correlation was observed between angles SNA & SNY, SNL, SNX & strong positive correlation was observed with angle SNY. Conclusions: We conclude that Point Y is the most nearing maxillary apical base landmark to Point A. Hence maxillary apical base landmark can be substituted by Point Y where identification of point A is not obvious.

      Suad Jaganjac, L. Schefe, Edin Avdagi&#;, Hajrudin Spahovi&#;, Mustafa Hiros.
      Introduction: Preoperative kidney tumor embolization is standard procedure for therapy in advanced kidney cancer. Preoperative embolization has a goal to reduce intraoperative bleeding and also to shorten the time of surgery. Materials and methods: We retrospectively observed 50 patients between 2000-2011, in which the preoperative embolization was performed. Mean age of patients was 64 years. All patients with preoperative embolization were compared with the group of 51 patients from Urology Sarajevo, who underwent nephrectomy without preoperative embolization. Results: Symptoms that are dominating among patients were haematuria and pain. Analysis of mean size of tumors based on CT evaluation showed statistically significance in between the biggest size of tumors in group from Hamburg( 9.11±3cm) and the smallest size of tumors in Sarajevo group (4.94±1.6cm) p=0.0001. Reason for this is difference in selection of patients for treatment in Hamburg from Sarajevo. Conclusion: Kidney as functional finishing organ is extremely suitable for transcatheter therapeutic procedures. The gold standard in the treatment of advanced and metastatic tumor is the nephrectomy. As preparation for nephrectomy in metastatic cancer total capillary embolization is performed. After embolization, surgery is shorter, procedure can be done 24-48 hours after embolization or delayed nephrectomy done 2-3 weeks after the intervention.

      Zalika Klemenc-Ketis,, Helena Vrecko.
      Introduction: Professionalism is essential for the development of mature physicians but not much education is devoted to that theme. Aim: We aimed to determine the views of undergraduate medical students on medical professionalism. Methods: This was a qualitative study, based on focus groups of the first and fifth-year undergraduate medical students. Transcripts of the focus groups were independently evaluated by two researches. Segments of transcripts, identified as important, were marked as verbatims. A grounded theory method with open coding was applied. A list of codes was developed and reviewed by both researchers until the consensus was reached. Then, the codes were reviewed and put into the categories and dimensions. Results: Students recognized 10 main medical professionalism dimensions (empathy, respect, responsibility, autonomy, trust, communication, difference between professional and private life, team work, partnership) and two dimensions associated with it (physician’s characteristics, external factors). Slight change of the attitudes towards a more self-centred future physicians’ figure was observed in the fifth-year medical students. Conclusion: The students have an appropriate picture of the physicians’ figure even at the beginning of their medical studies but still needs an education in professionalism. It seems that the fifth-year students perceive physicians as more self-centred when compared to their first-year colleagues.

      Critical thinking is defined as the mental process of actively and skillfully perception, analysis, synthesis and evaluation of collected information through observation, experience and communication that leads to a decision for action. In nursing education there is frequent reference to critical thinking and to the significance that it has in daily clinical nursing practice. Nursing clinical instructors know that students face difficulties in making decisions related to clinical practice. The main critical thinking skills in which nursing students should be exercised during their studies are critical analysis, introductory and concluding justification, valid conclusion, distinguish of facts and opinions, evaluation the credibility of information sources, clarification of concepts and recognition of conditions. Specific behaviors are essentials for enhancing critical thinking. Nursing students in order to learn and apply critical thinking should develop independence of thought, fairness, perspicacity in personal and social level, humility, spiritual courage, integrity, perseverance, self-confidence, interest for research and curiosity. Critical thinking is an essential process for the safe, efficient and skillful nursing practice. The nursing education programs should adopt attitudes that promote critical thinking and mobilize the skills of critical reasoning.

      Telemedicine itself is not the medical profession, it is not a medical specialty, but the way in which the medical profession conduct its activity. Therefore we are talking about tele otorhinolaryngology, tele cardiology or tele pathology. In the definition of a multitude of telemedicine that can be found in the literature is the following: Telemedicine is a system that supports the process of health care by providing ways and means for more efficient exchange of information that allows multitude of activities related to health care, including health care and health personnel, including education, administration and treatment. Telemedicine applications include: tele diagnosis, tele consultation, tele monitoring, tele-care, tele consultations and remote access to information contained in one or more databases. It turned out that telemedicine is an important factor in technological, professional, financial and organizational uniformity of development of the health system. Telemedicine, although a new area, to a large extent already changed the ways of providing health care, and even more influence on the ways of designing the future of medicine.

      Maryam Jahanbakhsh, Mohammed Sharifi, Masar Ayat.
      Background: The area of e-Health is broad and has an excellent growth potential. An increasing number of experts believe that e-Health will fuel the next breakthroughs in health system improvements throughout the world, but there is frequent evidence of unsustainable use of e-Health systems in medical centres, particularly hospitals, for different reasons in different countries. Iran is also a developing country which is presently adopting this promising technology for its traditional healthcare delivery but there is not much information about the use of e-Health systems in its hospitals, and the weakness and opportunities of utilization of such Hospital Information Systems (HIS). Methods: For this research, a number of Hospitals from Isfahan, Iran, are selected using convenient sampling. E-health research professionals went there to observe their HIS and collect required data as a qualitative survey. The design of interview questions was based on the researchers’ experiences and knowledge in this area along with elementary interviews with experts on HIS utilization in hospitals. Results: Efficient administration of e-health implementation improves the quality of healthcare, reduces costs and medical errors, makes healthcare resources available to rural areas, etc. However, there are numerous issues affecting the successful utilization of e-health in Hospitals, such as a lack of a perfect HIS implementation plan and well-defined strategy, inadequate IT-security for the protection of e-health-related data, improper training and educational issues, legal challenges, privacy concerns, improper documentation of lessons learned, resistance to the application of new technologies, and finally a lack of recovery plan and disaster management. These results along with some informative stories are extracted from interview sessions to uncover associated challenges of HIS utilization in Iranian hospitals. Conclusion: The utilization of e-health in Iranian hospitals, particularly those in Isfahan, is subject to several challenges and there is no proper long-term strategy plans for HIS initiation, development, and improvement in Iranian hospitals. In order to address these problems, six recommendations are provided. Hence, human resource and e-health professionals from third party consultancy companies along with medical university scholars have to assist such hospitals to undertake the proposed solutions in order to provide proper plans to overcome future challenges and have a mature HIS in accordance with expected HIS utilization from hospitals and medical universities.

      Background and Purpose: h-index has been always reviewed as one of the most useful criteria for evaluating the scientific outputs of researchers by the sciencometric experts. In this study, the h-index of 40 Iranian researchers accompanied with its relationship to assessment criteria of scientific outputs such as the number of articles, scientific age, number of citations and self-citation were reviewed. Materials and Methods: The first part of this study was related to the literature review. But the information of 40 Iranian researchers’ Citation Reports was observational extracted from WOS database and the Pearson correlation coefficient test was used to answer the research hypotheses. Results: Citation analysis showed that 40 selected researchers published 877 articles in web of science up to 9 January 2013. These articles have been cited 3858 time. The average of their h-index was estimated 38.5 ±12.12 Correlation coefficient test showed that there was a significant and direct relationship between the h-index and the number of papers, the number of citations and self-citation (Sig>0.05) but there was no significant relationship between scientific age and h-index (Sig> 0.05). Conclusions: Analysis of the data showed that the quantitative and qualitative indicators of the researchers with the same h-index had considerable differences. Therefore, only the h-index should not be a criterion for scientific ranking of the researchers and other complementary indexes such as M parameter and G index along with h-index must be used to be able to more accurately determine the degree of scientific influence of the researchers with the same h.

      Replicative Helicase DnaB interacts with DnaA, DnaC, DnaG, and DNA polymerase III to commence replication, increase the movement rate of the replication fork, and to assemble part of the primosome. The formation of the replication fork is limited by the ability to load DnaB to the DNA, thus DnaB has shown to be vital to a large extent. In the absence of DnaB, the replication fork is not maintained and in a state of inactivity the replication fork degrades and collapses. To further understand importance of this enzyme from an evolutionary perspective, a genomic analysis DnaB protein sequences, chosen from five Proteobacteria subclasses was performed. Our analysis indicates that, DnaB replicative helicases of Alphaproteobacteria and Epsilonproteobacteria have diverged at an earlier stage from Betaproteobacteria, Deltaproteobacteria and Gammaproteobacteria as well as from one another. Our results were further supported, when we reanalyzed and reconstructed the phylogenetic tree after the inclusion of sequences from Actinobacteria and Firmicute phylum. In addition, Betaproteobacteria, Deltaproteobacteria, and Gammaproteobacteria appear to share a closer common ancestor than from the other two subclasses. The Dot-plot analysis indicated that, the region between amino acid residues 320 to 400 was strongly conserved among all five subclasses.

    • Abstract: Publication year: 2014
      Source:Acta Informatica Medica
      Vahid Majidnezhad.
      Introduction: In recent years a number of methods based on acoustic analysis were developed for vocal fold pathology detection. These methods can be categorized in two categories: a) detection based on the phonemes b) detection based on the continuous speeches. While there are many researches which belong to the first category, there are few efforts for detecting vocal fold pathology based on the continuous speeches (second category). Methods: In this work, a method based on the Hidden Markov model Toolkit (HTK) for detecting vocal fold pathology in the Russian digits is developed which belongs to the second category. It employs a three state HMM for modeling each phoneme. Results: According to the results of the experiments, the proposed method achieves the 90% of detection accuracy. Conclusion: The proposed method is one of the first works for detecting vocal fold pathology based on the Russian digits (from 1 to 10) for Belorussian people. The reported accuracy is rather good and therefore it is recommended to use it as an auxiliary tool in medical centers.

      Introduction: An abfraction lesion is a type of a non-carious cervical lesion (NCCL) that represents a sharp defect on the cervical part of tooth, caused by occlusal biomechanical forces. The largest prevalence of the NCCL is found on the mandibular first premolar. The goal of the study is, by means of a numerical method – the finite element method (FEM), in an appropriate computer program, conduct a stress analysis of the mandibular premolar under various static loads, with a special reference to the biomechanics of cervical tooth region. Material and methods: A three-dimensional model of the mandibular premolar is gained from a µCT x-ray image. By using the FEM, straining of the enamel, dentin, peridontal ligament and alveolar bone under axial and paraxial forces of 200 [N] is analyzed. The following software were used in the analysis: CT images processing–CTAn program and FEM analysis–AnsysWorkbench 14.0. Results: According to results obtained through the FEM method, the calculated stress is higher with eccentric forces within all tested tooth tissue. The occlusal load leads to a significant stress in the cervical tooth area, especially in the sub-superficial layer of the enamel (over 50 MPa). The measured stress in the peridontal ligament is approximately three times higher under paraxial load with regard to the axial load, while stress calculated in the alveolar bone under paraxial load is almost ten times higher with regard to the axial load. The highest stress values were calculated in the cervical part of the alveoli, where bone resorption is most commonly seen. Conclusion: Action of occlusal forces, especially paraxial ones, leads to significant stress in the cervical part of tooth. The stress values in the cervical sub-superficial enamel layer are almost 5 times higher in relation to the superficial enamel, which additionally confirms complexity of biomechanical processes in the creation of abfraction lesions.

      Goal: the purpose of the current study was to estimate the predictive values of optical coherence tomography parameters in early, developed perimetric and terminal glaucoma. Methods: 180 eyes of 120 consecutive patients were evaluated in this retrospective cross sectional pilot study. Copernicus Spectral –domain optical coherence tomography with resolution of 3 mm obtained throught the optic nerve head were included. All examined eyes were divided to four groups (healthy,early, developed perimetric glaucoma and terminal glaucoma). The values of the thicknes of the retinal nerve fibre layer, the size of the disk, the volume of the cup, the E/D parameter and the size of the RIM were compared in four study groups. Results:The sensitivity of RNFL was 90,0%, specificity 82,0 %, positive predictability 83,3 % and negative predictability was 89,1 %. The total accuracy was 86,0 % and area under curve (AUC) was 0,878 for RNFL indeks compering early to developed glaucoma. The sensitivity for CUP was 78%, the specificity was 80,8 %, the positive predictability 81,2% and the negative predictability was 77,5 %. The total accuracy was 79,3 % and area under curve (AUC) was 0,86 compering early to developed glaucoma. The sensitivity for E/D was 82,0%, the specificity was 82,9 % the positive predictability 83,7 % and the negative predictability was 81,3 %. The total accuracy was 82,5 % and area under curve (AUC) for E/D was 0,89 compering eearly to developed glaucoma.The sensitivity for RIM was 78,0%, the specificity was 76,6 %, the positive predictability was 84,7 and the negative predictability was 67,7 %. The total accuracy was 77,5 % and area under curve (AUC) for the RIM compering the developed to terminal glaucoma was 0,792. The sensitivity of RNFL was 88,0 %, the specificity was 66,7 %, the positive predictability was 81,5% and the negative predictability was 76,9%. The total accuracy was 80,0% and the area under curve (AUC) for RNFL compering developed to terminal glaucoma was 0,815. The incrreasing 0,1 unit RNFL decreases the risk of developing glaucoma from early to another developed stage of glaucoma for 6,95%. The increasing of E/D for only one unit increases the risk to develop another stage of glaucoma for 18,75 times. The increasing of RNFL for only one unit decreases the risk of performing developed glaucoma from initial stage for 7,8%. The increasing for only one unit of CUP increases the risk to develop terminal glaucoma for 8,47 times and increasing for 0,1 unit of the value of RIM decreases the risk developing terminal glaucoma for 9,27%. The increasing for 0,01 unit of the E/D index increases the risk for terminal glaucoma for 23,23 times. The increasing for one unit of RNFL decreasing the risk developing terminal glaucoma for 5,7%.

      Smart phones are being increasingly used among health professionals. Ophthalmological applications are widely available and can turn smart phones into sophisticated medical devices. Smart phones can be useful instruments for the practice of evidence-based medicine, professional education, mobile clinical communication, patient education, disease self-management, remote patient monitoring or as powerful administrative tools. Several applications are available for different ophthalmological examinations that can assess visual acuity, color vision, astigmatism, pupil size, Amsler grid test and more. Smart phones can be useful ophthalmic devices for taking images of anterior and posterior eye segment. Professional literature and educational material for patients are easily available with use of smart phones. Smart phones can store great amount of informations and are useful for long term monitoring with caution for patient confidentiality. The use of smart phones especially as diagnostic tools is not standardized and results should be carefully considered. Innovative role of smartphone technology and its use in research, education and information sharing makes smart phones a future of ophthalmology and medicine.

      A group of 7 subjects underwent an experimental procedure which studied the potential changes in the maximal strength of the non-dominant arm elbow flexors. The programme duration was limited to 6 weeks during which the subjects practiced exercises 3 times a week, 3 series, on a Scott bench. Individual approach was applied to the external load and it was designed so that the weight being lifted would increase if the number of lifts in one series would exceed 3. The subjects were monitored through the one-repetition maximum 1 RM motor test and the isokinetic tests performed on biodex system, tested in 3 time periods (at the beginning, after 3 weeks, and after the 6th week). Of the 6 isokinetic tests, only the test for the maximum torque and the time for achieving the maximum torque have shown statistically important changes in terms of reduction in values, which was not expected. The one-repetition maximum test, unlike the isokinetic tests, has shown statistically important increase of the maximal muscle strength of 32.1% after the third week of exercising, and 46.8% after the six weeks of exercising. The statistical test for the correlation between the two variables has shown low correlation between these two tests. The values of the data of the two test types have not shown any correspondence among the subjects possibly due to the type of performance of the maximal muscle load during exercises, performed in conditions identical to the one-repetition maximum test, with similar and yet different conditions in the case of isokinetic tests. Most probably, due to the conditions in which the exercises and the tests took place, there is difference in the obtained results.

      Mehrdad Farzandipour, Zahra Meidani.
      Background: Websites as one of the initial steps towards an e-government adoption do facilitate delivery of online and customer-oriented services. In this study we intended to investigate the role of the websites of medical universities in providing educational and research services following the E-government maturity model in the Iranian universities. Methods: This descriptive and cross- sectional study was conducted through content analysis and benchmarking the websites in 2012. The research population included the entire medical university website (37). Delivery of educational and research services through these university websites including information, interaction, transaction, and Integration were investigated using a checklist. The data were then analyzed by means of descriptive statistics and using SPSS software. Results: Level of educational and research services by websites of the medical universities type I and II was evaluated medium as 1.99 and 1.89, respectively. All the universities gained a mean score of 1 out of 3 in terms of integration of educational and research services. Conclusions: Results of the study indicated that Iranian universities have passed information and interaction stages, but they have not made much progress in transaction and integration stages. Failure to adapt to e-government in Iranian medical universities in which limiting factors such as users’ e-literacy, access to the internet and ICT infrastructure are not so crucial as in other organizations, suggest that e-government realization goes beyond technical challenges.

      Leila Shahrzadi, Shahin Mojiri, Sima Janatian, Behjat Taheri, Hasan Ashrafi-rizi, Zeinab Shahrzadi, Razieh Zahedi.
      Introduction: Nowadays, anyone with any level of Internet knowledge can act as producer and distributor of information. It differs from most traditional media of information transmission, lack of information control and lack of quality management to contents. This leads to quality of health information on the internet is doubtful. The object of this study is guidance patients to select valid mental disorders and determine the quality of Persian mental disorders websites. Methods: The sample of this study comprised 29 Persian mental disorders websites that were chosen by searching the Google, Yahoo and AltaVista search engines for the Persian equivalents of the three concepts “depression,” “anxiety,” and “obsession”. website was created by individuals or organizations. Data collection was performed with the WebMedQual checklist. Websites was assessed based on indicators as content, authority of source, design, accessibility and availability, links, user support, and confidentiality and privacy (Maximum score for any website was 83, mean score 41.5 and minimum score was 0). Collected data analyzed by one sample T- test in SPSS 20. Findings presented by Mean score and optimal score. Results: Based on the WebMedQual scale the mean score of Persian mental disorders websites in sex constructs including “content” (7.02±2.10), “authority of source” (4.71±1.96),“accessibility and availability” (2.19±0.47), “links” (1.45±0.97), “user support” (4.28±1.33), and“confidentiality and privacy” (2.81±2.81) are poor and below average, but the score for the “design” (9.17± 1.59) is above average. The best website of mental disorders was that of the “IranianPsychological Association”. Conclusions: According to the results, only one website obtained the average score, so the quality of Persian mental disorders websites is low. Therefore, it is essential for users to criticize websites’ content and not trust them before evaluating them. It is better to use the ranked list websites or search on the internet by help information experts.

      Background and purpose: The user’s satisfaction with information system in fact denotes the extent the user is satisfied with the system’s achievement in fulfilling his/her information requirements. This study tries to explore the users’ satisfaction with hospital information systems (HISs) based on DeLone and McLean’s model focusing on the medical-teaching hospitals of Isfahan city. Methodology: This study which was applied and descriptive-analytical in nature was carried out in the medical-teaching hospitals of Isfahan city in 2009. Research population consisted of the system users from which a sample was selected using random sampling method. The size of the sample was 228. Data collection instrument was a self-developed questionnaire produced based on the satisfaction criterion in the DeLone and McLean’s model. Its content validity was assessed based on the opinions given by the computer sciences professionals with its estimated Cronbach’s alpha found to be 92.2%. The data were analyzed using SPSS software. Findings: As the findings of the study showed, the differences among the mean scores obtained for the satisfaction with different kinds of HISs in use in the hospitals were statistically significant (p value≤0.05). Generally, Kowsar System (old version) and Pouya Samaneh Diva system gained the highest and lowest mean scores for the criterion in question, respectively. The overall mean score for the satisfaction was 54.6% for different types of systems and 55.6% among the hospitals. Conclusion: Given the findings of the study, it can be argued that based on the used model, the level of users’ satisfaction with the systems in question was relatively good. However, to achieve the total optimum condition, when designing the system, the factors affecting the enhancement of the users’ satisfaction and the type of hospital activity and specialty must be given special consideration.
