Abstract
Background and Aim: Identification of possible animal sources of infection is
applied for preventing the outbreak and progressive epidemics of infection. The
aim of present study is isolation of pathogenic and opportunistic fungi from the
skin of ownership dogs with emphasize on transmission risk of fungal zoonoses in
rural areas of Meshkin Shahr, Ardebil province of Iran.
Materials and Methods: This cross-sectional and descriptive study was
performed in laboratory of Medical Mycology, School of Public Health, Tehran
University of Medical Sciences from April 2011 to November 2012. Hundred and
thirty dogs were studied. Collected scales and hair samples were examined by
direct smear and SC, SCC and DTM culture with the aim of full coverage of whole
fungal growth such as saprophytic and pathogenic fungi for 1-3 weeks.
Results: From 130 examined samples, Alternaria 41 (31.5%) as the most
frequent, Chaetomium 1 (0.9%) and Nattrassia 1 (0.9%) as the least frequent
saprophytic agents, were isolated from the samples.
Conclusion: The dogs in these areas are not the source of infection for
dermatophytosis and had no role in the epidemiology of the disease

Abstract
Background and Aim: Onychomycosis or nail fungus infection has an increasing prevalence with many effects on patients’ social life and mental health dermatophytes, yeasts and non-dermatophyte molds are among the best known agents of fungal infections of nails. The purpose of this study was to determine the prevalence of non-dermatophyte molds using morphological (direct examination and culture) and molecular (PCR) methods in patients referring to Medical Sciences Mycology Laboratory in Tehran, Iran.
Materials and Methods: In this study, samples were taken from 170 patients. For direct microscopic examination (DME), 15% KOH solution was used for the culture of samples, Sabouraud dextrose agar media (S) was applied together with chloramphenicol (SC) and chloramphenicol and cycloheximide (SCC). Meanwhile, differential tests were done for mycological diagnosis (slide culture), and 28SrDNA amplification and sequencing were performed for suspect or unknown samples.
Results: Of the 170 patients, 74 cases (43.5%) had onychomycosis, of which 53 cases (71.62%) were female and 21 cases (28.38%) were male. Also, of the 74 cases of onychomycosis, 40 cases (54.05%) were reported candidiasis, 21 cases (28.37%) non-dermatophyte molds, and 12 cases (16.21 %) dermatophytes.
Conclusion: The prevalence of onychomycosis in this study was 43.5% and the application of polymerase chain reaction (PCR) technique in cases of false positive, false negative and long-term culture was valuable meanwhile, given that all the samples that had positive results in DME with negative cultures were positive in molecular tests, this study reveals the power of molecular techniques compared with culture method.

Abstract
Background and Aim: In medical centers, after obtaining visceral clinical samples in suitable containers under certain circumstances, they are sent to mycology laboratory. Since sometimes it is impossible to test specimens immediately, therefore, they should be kept in the refrigerator. Thus, possibility of keeping samples, the confidently time of samples keeping in a refrigerator and the appropriate guidelines for the maintenance of visceral samples for clinical centers have a particular importance for practical purposes and are the aim of this study.
Materials and Methods: At first, the specimen was examined by KOH direct microscopic examination for detection of fungal elements. After primary culture of visceral samples on the Sabouraud dextrose agar with chloramphenicol (SC) medium, the samples were sequentially placed in a refrigerator at temperature 2-8 ºc for 1, 2, 24 and 48 hs and each sample with the specific mentioned time culturing was performed on the Sabouraud dextrose agar (S) and SC media. Then the results of growth were recorded.
Results: From 100 samples, 79 samples had grown, 20 samples with lack of growth and in 1 sample reduced growth were observed.
Conclusion: After 48 hours of cold temperatures (2-8 ºc) visceral fungal clinical samples are able to grow in culture media. So samples which were not tested immediately, could be stored at temperatures 2-8 ºc in the refrigerator.

Abstract
Background and Aim: Effective educational programs, is one of the most basic methods in prevention of Nosocomial infection. This study aimed to compare the effects of E-learning versus lecture-based education in prevention of Nosocomial infections among hospital staffs.
Materials and Methods: A randomized pre and posttest control group design was conducted on 98 hospital staffs in 2013 after allocating into two groups of "lecture-based education" and "E-learning”. Data were collected by a researcher-made questionnaire which its validity and reliability was confirmed by a pilot study. Wilcoxon, Paired and Independent sample T-test was conducted using SPSS, version18.
Results: There was a significant difference for outcomes before and after education based on two approach of lecture-based (p=0.01) and E-learning (p=0.01).The mean and standard deviation of knowledge in lecture-based education and E-learning group were 12.73± 2.76, 11.50 ± 2.64 respectively. The level of knowledge in the lecture group was significantly higher than that of participants in the E-learning group (p=0.02).
Conclusion: Despite the effectiveness of E-learning in learning and raising awareness of the learners, using of this method among health-related organizations need to empower employees, remove the barriers and suitable infrastructure.

Abstract
Background and Aim: Technical videos and images are of great importance in learning different topics of medical sciences. This study is conducted to determine the effect of videos and images in learning from students’ point of view and also their problems in accessing them.
Materials and Methods: This is a survey study. Data were collected by a self-made questionnaire and the population included postgraduate students of Qazvin University of Medical Sciences in the first semester of 94-95.
Results: More than half of the students stated that images and videos have an average or more-than-average effect on their learning achievements. There is no significant relationship between students’ fields of study and their feeling the need for specialized images and videos. To get advice, they refer more to their professors or classmates than to librarians. A large number of responding students had not heard even the names of specialized image-and-video databases or they had never used them before. Low-speed internet and filtering of sites are the most important factors in students’ failure to access their required images and videos while students themselves have ranked ‘unfamiliarity with specialized databases’ as the fourth important factor.
Conclusion: The students know the importance of images and videos in learning achievements, but since they don’t know the professional databases and don’t have an appropriate interaction with librarians, they resort to general search-engines and, as a result, they face with blocked sites and are deprived from what they really want.

Abstract
Background and Aim: Burn injury are one of the most common traumas worldwide and the sixth leading cause of death in Iran. The challenges related to the survival rate of burn patients, as well as the associated mortality cases, have led to advancements in the identification of risk factors. Early detection and recognition of these risk factors are essential, and the provision of predictive models can be beneficial. This research was conducted with the aim of reviewing the effectiveness of artificial intelligence in predicting survival in burn patients.
Materials and Methods: This study was a systematic review. A comprehensive search of Scopus, PubMed, IEEE, and Web of Science databases was conducted from inception to July 2023 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Keywords and Mesh terms related to burn, artificial intelligence, survival and prediction were used in the search.
Results: Out of 3599 identified studies, only nine were included in the analysis. Based on the articles reviewed, the effective factors in predicting survival or mortality in burn patients were classified into four main categories: demographic, clinical, tests and co-morbidities. Some of the known effective factors in patient survival, which have been examined in over 40% of studies, include age, gender, total body surface area, inhalation injury, and type of burn. The results showed that in the studies reviewed, the volume of the smallest dataset used in the analyses was 92 samples. In contrast, the volume of the largest dataset used was reported to be 66,611 samples. Among these studies, 33% have indicated that artificial neural network algorithms and random forest show the best performance. The criteria used to evaluate the models in the retrieved studies are diverse.
Conclusion: The use of machine learning algorithms in predicting the survival of burn patients is promising. The results obtained from identified influential factors can assist data science researchers in the data understanding phase and can serve as a roadmap in collecting the initial dataset.
