Abstract
Background: Recognizing the symptoms of acute coronary syndrome, as a leading cause of death among the elderly, is important for performing a successful intervention .This study aimed to predict the acute coronary syndrome based on the typical and atypical symptoms reported in the patients above and below 65 years. Materials and Methods: In this cross-sectional study, 446 patients with acute coronary syndrome were randomly selected among the cardiac intensive care units of 8 hospitals in Tehran. Data were collected using a checklist consisting of the symptoms of acute coronary syndrome. Results: Results showed that there was a statistically significant difference in the typical symptoms between the two age groups (above and below 65 years). The most typical symptom reported in patients above 65 years was dyspnea and the least one jaw or neck pain. Moreover, the most atypical symptom in patients over 65 years was palpitation and the least symptoms in the right side of the chest and indigestion, respectively. Logistic regression analysis showed that after the inclusion of both typical and atypical symptoms and age variable in the model, the incidence of chest symptoms, arm pain, dyspnea and neck or jaw pain can be predicted in the two age groups. Conclusion: The results of this study reveal that age, as a variable, can predict the most typical symptoms of acute coronary syndrome.

Abstract
Background: Infectious diarrheal diseases are a major cause of death in community, especially in children. Enteropathogenic Escherichia coli (EPEC) are considered as a major cause of children's diarrhea in developing countries. The aim of this study was to evaluate the prevalence of both typical Enteropathogenic (tEPEC) and atypical Enteropathogenic (aEPEC) E. coli isolated from patients admitted to the children's hospital in Tehran by the PCR method.
Materials and Methods: In this cross-sectional study, a total of 157 children diarrheal samples were collected from February 2016 to August 2017 and were sent to the microbiology department in the School of Public Health in Tehran University of Medical Sciences for testing. The identification of isolates was performed by conventional biochemical tests. The typical and atypical E. coli isolates were identified for the presence of eae, sxt1, sxt2 genes, and bfp A by the PCR method. The drug resistance patterns of isolated EPEC were tested by the agar disk diffusion method. The antibiotics used were amoxicillin-clavulanic, ampicillin, gentamicin, trimethoprim- sulfamethoxazole, ciprofloxacin, cefepim, Nitrofurantoin and imipenem.
Results: Out of 101 E. coli isolates, 7 were identified as EPEC. All the isolated strains carried eae but not stx1, stx2, and bfp A genes. Also, 100% of the isolates were resistant to amoxicillin-clavulanic and ampicillin.
Conclusion: A high prevalence of EPEC in children can be considered as a threat to the children's health. In this study, all the isolates were aEPEC.
