Introduction: Travel medicine is devoted to the health of travelers who visit foreign countries. It is an interdisciplinary specialty concerned not only with prevention of infectious diseases during travel but also with the personal safety of travelers and the avoidance of environmental risks. Methods: This review examines 15 appropriate papers by PRISMA from 28 papers searched in PubMed via the NCBI Entrez system. Results: A traveler's health and safety depends on a practitioner's level of expertise in providing pretravel counseling and vaccinations, if required. Conclusion: The standards of medical care given to travelers before, during and after travel should be as high as those practiced in every other field of medicine.
Aims: Epilepsy is one of the most common children diseases, and MRI is a method to understand its etiology. Since there was no MRI in many medical centers, the aim of this study was to compare the findings of CT scan and MRI without contrast in epileptic children. Instrument & Methods: In this descriptive-analytic study, 1-month to 14-year old epileptic children (n=160) referred to Pediatric Neurology Clinic of Yazd Shahid Sadoughi Medical University were studied in September 2012. Data was recorded in a questionnaire via interviews with the parents, biography, physical exams, and investigating the findings of CT scan and MRI. Data was analyzed in SPSS 15 software using Chi-square test. Findings: There were normal and abnormal CT scans in 121 (75.6%) and 39 (24.4%) children, respectively. There were normal and abnormal MRI findings in 84 (52.5%) and 76 (47.5%) children, respectively. The results of CT scan and MRI were consistent in 119 (73.4%) children (p=0.001). There were more prevalent abnormal CT scans in less than 6 months children, developmental delayed children, abnormal physical exam, and epileptic abnormal electroencephalography. There were more prevalent abnormal MRI cases in 2-14 years children, developmental delayed children, abnormal physical exam, focal seizure, and non-specific abnormal electroencephalography. Conclusion: To investigate 2-14 years old epileptic children, focal seizure, and non-specific abnormal electroencephalography, MRI is preferable than CT scan. The latter is useful in less than 6 months children, developmental delayed children, abnormal physical exam, and epileptic abnormal electroencephalography.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
