Diagnostic Accuracy of Ultrasound in Detection of Traumatic Lens Dislocation

Introduction: Traumatic eye injuries (TEI) involved about 3% of cases referred to the emergency departments of developing countries. Lens dislocation is one of the critical cases of ophthalmic emergencies. The present study was aimed to evaluate the diagnostic accuracy of ultrasonography in detection of traumatic lens dislocation. Methods: In this cross-sectional study the findings of ultrasonography and orbital computed tomography (OCT) of head and face trauma patients, referred to Imam Reza hospital, Tabriz, Iran, from July 2013 to June 2014, have been compared. The sensitivity, specificity, positive and negative likelihood ratio, positive and negative predictive value, and accuracy of ultrasonography were calculated. Cohen's kappa coefficient was presented to assess the agreement of ultrasonography with OCT findings. Results: One hundred thirty patients with the mean age of 35.4±18.0 were evaluated (75.4% male). Sensitivity and specificity of ultrasonography were 84.6% (95% Cl: 53.7-97.3) and 98.3% (95% Cl: 93.3- 99.7), respectively. Also, positive and negative likelihood ratio were calculated 49.5 (95% Cl: 12.3-199.4) and 0.15 (95% Cl: 0.04- 0.56), respectively. Cohen's kappa coefficient of 0.83 (95% Cl: 0.66-1.0; p<0.0001) was representative of excellent agreement of these two tests. Conclusion: The finding of this project was representative of 84.6% sensitivity, 98.3% specificity, and 96.9% accuracy of ultrasonography in detection of traumatic lens dislocation. It seems that in cases which OCT is not possible, ultrasonography could be an acceptable option to assess traumatic eye injuries

One year evaluation of trauma patients’ death

Worldwide trauma is currently the sixth leading cause of death, according to 10% of mortalities (1,2). Injury impact and the death from trauma are more common in males than females. People aged between 15 and 45 years include about half of the trauma deaths (3). Citizens of low- and middle-income countries (LMICs) account for 89% of all deaths from trauma worldwide. This is particularly because of hospitals’ lack of facilities, equipments, and peripheral care systems (4,5)

Outcomes of cardiopulmonary resuscitation in the emergency department

Objective: Cardiopulmonary resuscitation (CPR) is a lifesaving technique useful in the prevention of death or delaying it in a person with cardiac arrest. In this regard, demographic information about patients who need CPR is vital. Methods: In this cross-sectional study patients with cardiopulmonary arrest or arrhythmias admitted to Imam Reza and Sina educational hospitals of Tabriz University of Medical Sciences from 22 December 2013 to 21 December 2014 entered the study. Demographic information such as age, sex, cardiopulmonary resuscitation time, the place of cardiopulmonary arrest (outside or inside the hospital), the duration of resuscitation process, success or failure of the resuscitation process and the mechanism of cardiopulmonary arrest were obtained. Results: From a total of 354 cases of cardiopulmonary resuscitation, 281 cases (79%) were unsuccessful and 73 cases (21%) were successful. The average age of patients was 59 ± 22 years. The average time of the resuscitation process was 31 ± 12 minutes. There was a significant difference between the mean of age and resuscitation time in patients who had experienced successful or unsuccessful resuscitation (P = 0.0001). There was a significant relationship between sex and the success rate of resuscitation (P = 0.0001). In addition, a significant relationship between the success of the resuscitation operation and the ward of resuscitation was observed (P = 0.0001). Conclusion: The most common mechanism leading to cardiopulmonary arrest among patients was asystole. In this regard, no significant difference was observed between successful and unsuccessful resuscitation processes. It was also observed that the success of resuscitation from 8 am to 4 pm was more than any other time period
