Objective: According to the most recent guidelines, the recommended imaging approaches forthe diagnosis of pneumonia are chest X-ray (CXR) and computed tomography (CT) scan. However,there are limitations to these approaches. Lung ultrasound (LUS) has attracted a lot of attentionin intensive care units (ICUs) and emergency departments. Considering the importance of thetimely diagnosis and proper treatment of pneumonia, this study aimed to determine the diagnosticvalue of bedside LUS in comparison to chest CT scans in patients with suspected pneumonia orunspecified CXR findings in the emergency department.Methods: This prospective descriptive-analytic study was conducted in the emergency departmentof Imam Reza hospital. Patients aged 3 years and older with early diagnosis of pneumonia orany unspecified CXR findings with an indication of CT scan were included in the study. LUS wasperformed with a deep curved and linear surface probe. The results obtained from the chestultrasound were compared with the results obtained by CT scan as the diagnostic gold standard.Results: A total of 175 patients were included in this study. According to the results, the sensitivityand specificity of LUS in the diagnosis of subpleural consolidation were 94.1% and 100%,respectively, and the positive predictive value and the negative predictive value were 100% and33.3%, respectively. The sensitivity and specificity of LUS in diagnosing pleural effusion were69.2% and 100%, respectively, and the positive predictive value and the negative predictive valuewere 100% and 90.7%, respectively. Furthermore, the sensitivity of LUS in diagnosing dynamic airbronchogram was 98%.Conclusion: According to the findings of the present study, in patients suspected of pneumonia,LUS is more sensitive and specific in the diagnosis of pneumonia and is less time-intensive andcostly. Additionally, the ultrasound device is easily portable and accessible. It can be widely used anddoes not have the secondary side effects of ionizing radiation in patients. However, the technician’sskill in performing ultrasound is a matter of importance.

Objective: In recent years, there has been a great attention concerning red blood cell distribution width (RDW) in clinical decisions as well as determining the severity of diseases. This study was conducted to evaluate the primary level of RDW to predict hospital mortality in pancreatitis.
Methods: This was a descriptive analytical study performed on 100 patients with acute pancreatitis in the emergency department of Imam Reza hospital of Tabriz University of Medical Sciences. In this study, the primary level of RDW in patients with acute pancreatitis presenting to the emergency ward was collected and after patients’ admission we followed them. Also, the admission outcome (mortality or discharge) of patients was registered, and finally we evaluated the predictive value of RDW in determining the patient’s outcome in hospital.
Results: In our study, 47 patients were male, and 53 patients were female. Mean RDW in patients was 13.82 ± 1.69. Five patients died during the study. Mean RDW in dead patients and other patients was 16.44 ± 4.22 and 13.68 ± 1.37, respectively (P < 0.001). The cut-off point of 14.55 for RDW with 80% sensitivity and 85% specificity was determined for predicting mortality in patients.
Conclusion: Based on our study results, the initial RDW level is an independent factor for predicting in-hospital mortality in pancreatitis but not for determining the need for surgery or admission to the intensive care unit (ICU).
