Transient Unexplained Shock in 30-Year-Old Trauma Patient

Shock as an inadequate tissue perfusion is one of the frequent causes of death in trauma patients. In this context, there are various reasons for hemodynamic instability and shock including hypovolemic (hemorrhagic), obstructive (cardiac tamponade, tension pneumothorax), cardiogenic, neurogenic, and rarely septic. In the present report, a 30-year-old trauma patient with full clinical signs and symptoms of shock referred while had unknown origin; it was finally recognized as anaphylactic shock.

Thoracic Pneumorrhachis in Patient with Lumbar Fractures; a Case Report

Pneumorrhachis as a relatively rare condition may be an indication of substantial intra-spinal column injury. Here we report a 39-year-old man was admitted because of low back pain and dyspenea after locating between motor vehicle and wall three days before admission. On arrival, physical exams and vital signs were normal. Computed tomography (CT) scan showed bilateral pleural effusion, fracture of ribs number 8, 9 and 10 in lower left side of thorax, fracture of vertebra in L2-L4, and air bubbles in upper thoracic spinal canal.

Ubiquitin C-Terminal Hydrolase-L1 (UCH-L1) in Prediction of Computed Tomography Findings in Traumatic Brain Injury; a Meta-Analysis

Introduction: Ubiquitin C-terminal hydrolase-L1 (UCH-L1) is one of the promising candidates, with an acceptable diagnostic value for predicting head computed tomography (CT) scan findings. However, there has been a controversy between studies and still, there is no general overview on this. Therefore, the current systematic review and meta-analysis attempted to estimate the value of UCH-L1 in predicting intracranial lesions in traumatic brain injury.Methods: Two independent reviewers screened records from the search of four databases Medline, Embase, Scopus and Web of Science. The data were analyzed in the STATA 14.0 statistical program and the findings were reported as a standardized mean difference (SMD), summary receiver performance characteristics curve (SROC), sensitivity, specificity, and diagnostic odds ratio with 95% confidence interval (95% CI).Results: Finally, the data of 13 articles were entered into the meta-analysis. The mean serum level of UCH-L1 was significantly higher in patients with CT-positive than in TBI patients with CT negative (SMD = 1.67, 95% CI: 1.12 to 2.23, I2 = 98.1%; p <0.0001). The area under the SROC curve for UCH-L1 in the prediction of intracranial lesions after mild TBI was 0.83 (95% CI: 0.80 to 0.86). Sensitivity, specificity and diagnostic odds ratio of serum UCH-L1 was 0.97 (95% CI: 0.92 to 0.99), 0.40 (95% CI: 0.30 to 0.51) and 19.37 (95% CI: 7.25 to 51.75), respectively. When the analysis was limited to assessing the serum level of UCH-L1 within the first 6 hours after mild TBI, its sensitivity and specificity increased to 0.99 (95% CI: 0.94 to 1.0) and 0.44 (95% CI: 0.38 to 0.052), respectively. In addition, the diagnostic odds ratio of 6-hour serum level of UCH-L1 in the prediction of intracranial lesions was 680.87 (95% CI: 50.50 to 9197.97).Conclusion: Moderate level of evidence suggests that serum/plasma levels of UCH-L1 have good value in prediction of head CT findings. It was also found that evaluation of serum/plasma level of UCH-L1 within the first 6 hours following TBI would increase its predictive value. However, there is a controversy about the best cutoffs of the UCH-L1

A Young Man with Myocardial Infarction due to Trenbolone Acetate; a Case Report

Over the four decades, a significant decrease has been observed in age-related mortality caused by cardiovascular disease. People in developing countries suffer from CAD at a relatively younger age and about half of MI occurs under the age of fifty years. Abuse of anabolic steroids is one of the less common causes of atherosclerosis. In this report, a 23-year-old body builder male referred to emergency department (ED) with myocardial infarction (MI) following chronic Trenbolone acetate consumption. It seems that a comprehensive history of steroid consumption in young patients referred to ED with the chief complaint of chest pain or its equivalents is necessary in adjunct to other cardiac risk factors

Knowledge and Attitude Regarding Organ Donation among Relatives of Patients Referred to the Emergency Department

Introduction: Organ donation is one of the surviving procedures which can increase the life expectancy of end-stage patients. Inappropriate beliefs and attitude of individuals to organ donation, their poor knowledge, and the socio-economic level are one of the most important barriers for organ donation. Therefore, here knowledge and attitude levels among relatives of trauma patients regarding organ donation were evaluated. Methods: This cross-sectional study was done on relatives of trauma patients referred to the emergency department of Sina Hospital, Tabriz, Iran, through 2013 to 2014. The questionnaire included parts of demographic data and socio-economic situations as well as status of knowledge and attitude regarding organ donation. A score between 0-7 was belonged to each person based on his/her level of knowledge. Attitude level had a score between 0-12. Chi- square, Fisher, and Mann–Whitney U test were performed to assess the relation between demographic variables and the level of knowledge and attitude. P<0.05 was considered as a significant level. Results: 79 persons (57.1% male) with the mean age of 31.3±11.3 years were evaluated. 57 (73.1%) of subjects agreed with organ transplant. The main causes of disagreement among relatives regarding organ donation were dissatisfaction of the donor's relatives (25%) and religious issues (15%). 49 (62.02%) studied people had inappropriate attitude and 27 (34.2%) ones had good knowledge. male gender (OR=5.87; 95%CI: 3.32-8.42; p=0.001) and self-employed job (OR=7.78; 95%CI: 4.64-10.92; p=0.001) are independent factors associated with poor knowledge about organ donation. Self-employed job (OR=3.86; 95%CI: 1.41-6.11; p=0.009) and poor knowledge (OR=15.3; 95%CI: 9.03-21.57; p<0.001) were related to inappropriate attitude toward organ donation. Conclusion: The present study showed that 73.1% of participants agreed with organ donation. The major causes of disagreements were dissatisfaction of other relatives and religious beliefs. 62.0% of the studied people had positive view regarding organ donation and 34.2% of them well-informed about. The most important causative factors for poor knowledge in this context were male gender and self-employed occupation. In addition, poor knowledge and self-employed job were two factors associated with inappropriate attitude toward organ donation

Clinical Scoring Systems in Predicting the Outcome of Acute Upper Gastrointestinal Bleeding; a Narrative Review

Prediction of the outcome and severity of acute upper gastrointestinal bleeding (UGIB) has significant importance in patient care, disposition, and determining the need for emergent endoscopy. Recent international recommendations endorse using scoring systems for management of non-variceal UGIB patients. To date, different scoring systems have been developed for predicting the risk of 30-day mortality and re-bleeding. We have discussed the screening performance characteristics of Baylor bleeding score, the Rockall risk scoring score, Cedars-Sinai Medical Center predictive index, Glasgow Blatchford score, T-score, and AIMS65 systems, in the present review.Based on the results of this survey, there are only 3 clinical decision rules that can predict the outcome of UGIB patients, independent from endoscopy. Among these, only Glasgow Blatchford score was highly sensitive for predicting the risk of 30-day mortality and re-bleeding, simultaneously.

Epidemiology of Alcohol Poisoning and Its Outcome in the North-West of Iran

Introduction: Alcohol poisoning is one of the main preventable causes of death, disability, and injury in many societies. Ethanol and methanol are the most prevalent kinds of alcohol used. There is no any exact reports of alcohol poisoning and its outcome in Iranian society. Therefore, the present study was assessed the status of alcohol poisoning and its outcome in referees to the emergency department. Methods: This is a cross-sectional study which was done from July 2013 to 2014 in Sina Trauma Center, Tabriz, Iran. The studied population included all alcohol poisoning cases referred to this center. Demographic variables, clinical evaluation, laboratory tests, and patient's outcome were evaluated. To assess the relation between evaluated factors and outcome of alcohol poisoning. After univariate analysis a multivariate logistic regression was applied to evaluate independent risk factors for death. P<0.05 was considered as a significant level. Results: Lastly 81 patients with alcohol poisoning were entered to the study (91.4% male) with the mean age of 27.9±10.4 years. Ten (12.3%) subjects were dialyzed and 34 (42%) cases hospitalized that 3 (3.7%) of them died. The multivariate logistic regression test displayed that plasma creatinine level (OR=2.2 95%Cl: 1.8-2.5; p=0.015) and need for dialysis (OR=6.4; 95%Cl: 5.3-7.5; p<0.001) were the only risk factors of death among these patients. Conclusion: The findings of the present study revealed that total mortality rate of referees to the emergency with alcohol poisoning was 3.7% all of whom related to methanol poisoning. Based on this result, the mortality rate of methanol poisoning was estimated 20%. Need for dialysis and increasing the creatinine level were accounted as independent risk factors of death

Poisonous Spiders: Bites, Symptoms, and Treatment; an Educational Review

More than 40,000 species of spiders have been identified in the world. Spider bites is a common problem among people, however few of them are harmful but delay in treatment can cause death. Since the spider bites are risk full to human, they should be taken seriously, especially in endemic areas. Our objective in this review was to study about poisonous spiders and find out treatments of them. Therefore we collected related articles from PubMed database and Google Scholar. Three important syndromes caused by spider bites are loxoscelism, latrodectism and funnel web spider syndrome. Many treatments are used but much more studies should have done to decrease the mortality. In this review, we describes different venomous spiders according to their appearance, symptoms after their bites and available treatments.

Screening Performance Characteristic of Ultrasonography and Radiography in Detection of Pleural Effusion; a Meta-Analysis

Introduction: The role of ultrasonography in detection of pleural effusion has long been a subject of interest but controversial results have been reported. Accordingly, this study aims to conduct a systematic review of the available literature on diagnostic value of ultrasonography and radiography in detection of pleural effusion through a meta-analytic approach. Methods: An extended search was done in databases of Medline, EMBASE, ISI Web of Knowledge, Scopus, Cochrane Library, and ProQuest. Two reviewers independently extracted the data and assessed the quality of the articles. Meta-analysis was performed using a mixed-effects binary regression model. Finally, subgroup analysis was carried out in order to find the sources of heterogeneity between the included studies. Results: 12 studies were included in this meta-analysis (1554 subjects, 58.6% male). Pooled sensitivity of ultrasonography in detection of pleural effusion was 0.94 (95% CI: 0.88-0.97; I2= 84.23, p<0.001) and its pooled specificity was calculated to be 0.98 (95% CI: 0.92-1.0; I2= 88.65, p<0.001), while sensitivity and specificity of chest radiography were 0.51 (95% CI: 0.33-0.68; I2= 91.76, p<0.001) and 0.91 (95% CI: 0.68-0.98; I2= 92.86, p<0.001), respectively. Sensitivity of ultrasonography was found to be higher when the procedure was carried out by an intensivist or a radiologist using 5-10 MHz transducers. Conclusion: Chest ultrasonography, as a screening tool, has a higher diagnostic accuracy in identification of plural effusion compared to radiography. The sensitivity of this imaging modality was found to be higher when performed by a radiologist or an intensivist and using 5-10MHz probes
