Introduction: Electrocardiographic (ECG) corrected QT (QTc) interval and dispersion were used as prognostic variables in adult patients and limited studies showed the relationship between QTc prolongation and dispersion with some clinical situations in newborn babies. Aim: In the present study, we compared the electrocardiographic (ECG) variables such as QTc interval and dispersion of healthy full-term and pre-term neonates with those who suffered from non-cardiac illnesses. Methods: This prospective cohort study involved 127 neonates including four study groups: normal full-term neonates, ill full-term neonates, normal pre-term neonates and ill pre-term neonates. Neonates with fever, apnea, poor feeding, tachypnea, muscle retraction, grunting, reduced neonatal reflexes, positive blood culture or antibiotic therapy > 3 days were considered as ill neonates. QTc interval and dispersion were calculated and compared among the four groups. Results: QTc interval was significantly (p = 0.012) higher in ill pre-term neonates in comparison with normal pre-term ones (418.74± 54.29 ms vs. 386.66± 39.26 ms). QTc dispersion was calculated and showed significantly higher mean values in ill pre-term neonates when compared with normal full-term, ill full-term and normal pre-term ones. QT dispersion and QTc dispersion of dead neonates were significantly (p= 0.0001-0.01) higher than alive ill pre-term neonates at 3, 7 and 28 days after birth. Conclusion: QTc interval and dispersion seem to represent non-invasive, reliable predictors of mortality in pre-term ill neonates, but further investigation is needed to confirm cutoff values for the risk assessment.

Introduction: Cervical spondylotic myelopathy (CSM) is a neck condition that arises when the spinal cord becomes compressed due to the wear-and-tear changes that occur in the spine as we age. Case report: The patient was a 52-year-old male, who complains of neck pain, paranesthesia in upper extremities, lower back pain and bilateral calf pain, muscle weakness in the lower and upper extremities, fatigue and general body pain that started four weeks ago associated with other clinical manifestation. Magnetic Resonance Imaging (MRI) of the cervical spine revealed canal stenosis and increased T2 signal within the spinal cord. CSM is a rare condition there are very few or no cases described in literature when CSM in C3/C4 is associated with a lack of B12 and other pathologies such as and hypoplasia of the mastoid air-cell with system maxillary sinus aplasia. Conclusion: The case described in the present study suggested that the incidence of CSM may be correlated with VB12 deficiency, particularly for cases in which the clinical manifestations and the imaging do not fully match.

Introduction: The technological advancements have transformed the society into a global forum influencing the educational processes and learning environments. Medical education is no exemption with an increasing trend to use the social media and smart phones for teaching and learning. Facebook, WhatsApp, Instagram, YouTube and Edmodo are the platforms promoting collaborative learning, improved communication and knowledge sharing. Aim: This study aims to review the use of smart phones and social media in the context of medical education. It reviews the usage of smart phone and social medical applications including Facebook, WhatsApp and Edmodo for teaching and learning in medical education. Results: The use of personal smartphones for teaching and learning among medical community is highly prevalent and increasing day by day. Medical students use the mobile application for online textbooks (70%), medical podcasts (60%), medical calculator (75%), online lecture (50%) and notes taking (45%). Relevant studies conclude that the majority of students use smart phones for education (62.7%), communication (81.7%) and recreation (82.5%). Social media has a great potential in educational setting and provide students a chance to involve, share and express knowledge and information with each other. Facebook, WhatsApp and Edmodo are the commonly used applications having multiple benefits like collaboration, feedback and engagement but negative aspects including addiction, distraction and maintenance of privacy have also been found. Conclusion: The review article concludes that social media is a powerful instrument for social interactions and is also used as a tool for teaching and learning. The integration of social media with traditional class teaching in medical education has clear advantages but there is a debate about the probable disadvantages as well.

Introduction: Human amnion membrane mesenchymal stem cells (hAMSCs) and human umbilical cord mesenchymal stem cells (hUC-MSCs) are potential, non invasive sources of stem cells used for bone tissue engineering. Phenotyping characterization is an extremely important consideration in the choice of the appropriate passage in order to maximize its osteogenic differentiation potential. Aim: To explore phenotype characteristics and compare osteogenic differentiation potential of hAMSCs and hUC-MSCs. Method: Isolation and culture were performed on hAMSCs and hUC-MSCs from a healthy woman in her 38th weeks of pregnancy. CD90, CD105 and CD73 phenotype characterization was done in passage 4-7. An osteogenic differentiation examination of hAMSCs and hUC-MSCs with Alizarin red staining and RUNX2 expression was performed in the passage that had appropriate expressions of phenotype characteristics. Results: The expression of CD90 hUC-MSCs was higher than that of hAMSCs in all passages. CD105 hUC-MSCs was higher in passage 4-6, while CD105 hAMSCs was equal to that of hUC-MSCs in passage 7. CD73 hUC-MSCs was higher than hAMSCs in passage 4 and 5, while in passage 6 and 7 hAMSCs was higher than hUC-MSCs. There was a decrease in the number of CD90, CD105 and CD73 on hAMSCs and hUC-MSCs in passage 5, then determined as appropriate passage. Alizarin red staining examination showed calcium deposition and revealed no significant difference, but RUNX2 expression of hUC-MSCs was significantly higher than that for hAMSCs. Conclusion: Both hAMSCs and hUC-MSCs had phenotype characteristics of mesenchymal stem cell and showed ostegenic differentiation potential.

Introduction: In Yemen, the largest cholera epidemic of modern times started in late 2016. By March 2018, more than one million cases had been reported. A national electronic Disease Early Warning System (eDEWS) for infectious disease surveillance was established in 2013.
Aim: This study assessed the eDEWS's timelines for reported cholera cases.
Methods: Quantitative data published in eDEWS and the Weekly Epidemiological Bulletin of the Yemen Ministry of Health from March 2013 until March 2018 were analyzed. For assessing the early detection of cholera cases, 262 weekly bulletins were reviewed. The raw data of the immediately generated eDEWS alerts during the first outbreak wave were used to assess response timeliness.
Results: Reported cholera incidence peaked at 1,698 cases (first wave) in 2016 week 49, and then reached 46,667 cases (second wave) in 2017 week 26. The mean time period between reporting and the first response was 2.85 days. Only 31% of the eDEWS alerts were verified within the first 24 hours, and the majority (83%) were verified within one week. There were major differences in the timeliness between the governorates, ranging from 8%-62% for reporting within the first 24 hours.
Conclusion: The eDEWS is able to detect and alert health authorities about cholera cases even under conditions of ongoing war and civil war, however, the timeliness of the response needs improvement.

Introduction: Deep vein thrombosis (DVT) is a common cause of admission to the emergency departments (ED). Doppler ultrasonography of the entire lower limb is the first-line imaging modality. But most EDs do not access to full-time radiologists which can lead to delayed diagnosis. Aim: The aim of this study was to evaluate the diagnostic accuracy of three-point compression ultrasonography performed by emergency medicine resident for diagnosis of DVT. Methods: This prospective diagnostic study was carried out at Imam Khomeini Hospital in Sari from March 2018 to November 2018. For all patients with suspected lower extremity DVT, first bedside 3-point compression ultrasound were performed by a third year emergency medicine resident at ED. Then Doppler ultrasonography were performed by a radiologist in the radiology department, as a reference test. Sensitivity, specificity, and positive predictive value of the three-point compression ultrasound performed by emergency medicine resident was calculated. Results: Of the 72 patients enrolled in our study, 50% of the patients were male, with an average age of 36±19 years. The mean of patient admission time to perform ultrasonography by an emergency medicine resident and radiologist were 14.05±19 and 216±140.1 minutes, respectively. The two groups had a statistically significant difference (P<0.0001). In ultrasonography performed by emergency medicine resident and doper ultrasonography by radiologist, 91.67% and 36.1% of patients were diagnosed with DVT, respectively. Although the ultrasonography performed by emergency medicine resident has a relatively low sensitivity (53.8%), it has a good specificity (85.7%). The positive and negative predictive value was 70 and 75%, respectively. Conclusion: Although the results of this study indicate insufficient sensitivity of bedside three-point compression ultrasound performed by emergency medicine resident in diagnosis of lower limb DVT, the specificity, positive and negative predictive values and positive likelihood ratio were almost appropriate.

Introduction: One attractive research area in the computer science field is soft biometrics. Aim: To Identify a person’s gender from an iris image when such identification is related to security surveillance systems and forensics applications. Methods: In this paper, a robust iris gender-identification method based on a deep convolutional neural network is introduced. The proposed architecture segments the iris from a background image using the graph-cut segmentation technique. The proposed model contains 16 subsequent layers; three are convolutional layers for feature extraction with different convolution window sizes, followed by three fully connected layers for classification. Results: The original dataset consists of 3,000 images, 1,500 images for men and 1,500 images for women. The augmentation techniques adopted in this research overcome the overfitting problem and make the proposed architecture more robust and immune from simply memorizing the training data. In addition, the augmentation process not only increased the number of dataset images to 9,000 images for the training phase, 3,000 images for the testing phase and 3,000 images for the verification phase but also led to a significant improvement in testing accuracy, where the proposed architecture achieved 98.88%. A comparison is presented in which the testing accuracy of the proposed approach was compared with the testing accuracy of other related works using the same dataset. Conclusion: The proposed architecture outperformed the other related works in terms of testing accuracy.

Introduction: In order to improve the level of public administration, the Greek government mandated the use of the electronic system “Clarity”, requiring all public bodies to upload their administrative and financial data on the Internet in an effort to curb corruption, increase control and create a sense of trust between the state and the public. Particular emphasis was placed on the application of the “Clarity” system into the healthcare sector, especially in hospitals. Aim: The goal of this primary quantitative and qualitative research is to investigate the implementation of the “Clarity” in the Greek health system in terms of transparency the administrative and financial activity of the NHS hospitals for both health professionals and users. Methods: Research materials include examination of the AHEPA Hospital (Thessaloniki) archives, which is used as a case study, and qualitative research questionnaires. A study sample has also been provided by all licensed program users (32 participants). Results: According to the findings within a university general hospital, this program helps to promote hospital management and guarantees a controlled and secure sharing of the majority of the administrative acts and decisions adopted. Also “Clarity” consolidates reliability and accountability; it promotes the direct communication of services and contributes towards a better systematization and data collection in order to upgrade the administrative/functional capacity and the control of expenditures. Conclusion: The benefits from the program “Clarity” can be increased through the functional interconnection of other similar electronic networking programs, setting as a prerequisite the creation of appropriate material infrastructure and personnel training.

Introduction: Nowadays, potential patients surf the internet to check the websites of health care organizations to select the most suitable health organization for their needs within the perspective of health tourism. To this effect, dental health tourism as a subset of health tourism is considered to be a developing sector. Aim: The aim of the study was to assess whether websites are effectively used as media tools by dental health care organizations, which serve as currently active as well as promising components of health tourism in Turkey. Methods: In this cross-sectional study, 555 websites of dental health care organizations were examined. Web pages were evaluated by using E-Information Quality Scale of the Health Centre. A low score indicates well-designed websites. Results: Scores related to “contact information” and “website layout” were lower in the private ones (n:146) than the public institutions (n:409)(p=0.000, p=0.011). It was observed that 80.8% (n:122) of the websites with foreign language options (n:151), were private institutions); whereas, public institutions only constitute 19.2% (n:29) of the total. All sub-group scores in the scale were lower in the organizations offering foreign language alternatives in contrast to the ones without foreign language options (p<0.05). Conclusion: In private dental health care organizations,“ contact information” and “website layout” of websites were observed to be the most prominent features in the conduct of public relations activities. Websites with foreign language alternatives were well-designed due to the fact that language options were considered to be an incentive for the health tourists.
