  Background &Objectives :�Hyphema which commonly caused by the blunt trauma, is defined as blood accumulation in the anterior chamber of the eye. It is associated with several complications from which secondary hemorrhage is more important. This study was aimed to determine Tranexamic acid effect on reduction of the secondary hemorrhage in traumatic hyphema.

  Methods: This study was a randomized controlled trial in 54 patients with traumatic hyphema referred to ophthalmology clinic of Alavi Hospital in Ardabil during 2006-2008. The patients were divided into two groups. Half of the patients received Tranexamic acid and the rest used placebo. After examination of the eyes, the data were analyzed by using Chi-square^�and Student-t tests.

  Results : In this study 79.6% of patients were men and the rest were women. They had 19.8 ± 9.44 years old as mean. The vision for 33.3% of the individuals showed light perception, 29.6% hand motion and 35.2% of them indicated finger count. 1.9% of patients had grade I, 11.1% grade II, 38.9% grade III and 48.1% grade IV hyphema. The patients who received Tranexamic acid did not show secondary hemorrhage but five untreated individuals were undergone bleeding.

  Conclousion : Tranexamic acid reduced secondary hemorrhage in patients with blunt trauma-related hyphema. We suggest further studies of relationship between intra-ocular pressure and secondary hemorrhage rate.

Background & objectives: Trauma is one of the most common causes of death in  the age range 1 to 44 and the third cause of death regardless of age. Abdominal trauma is one of the most common types of trauma. This study aimed to investigate the frequency of causes of laparotomy in penetrating and blunt abdominal traumas in 2016.
Methods: This descriptive study was conducted on 120 medical records of patients hospitalized for penetrating and blunt abdominal traumas in Fatemi Hospital, Ardabil, 2016. The inclusion criterion consisted of all patients undergoing laparotomy due to abdominal trauma. In this study, age, gender, education level, type of trauma (blunt or penetrating), results of laparotomy surgery, physical examination and paraclinical findings of patients before operation were collected by a researcher- made checklist.
Results: The results showed that 80% of the patients were male and 35% were in the age range 20-29years. Of patients, 38.3% had penetrating trauma and 61.7% blunt trauma. The most common mechanism of blunt abdominal trauma was car accident (83.8%). Penetrating object was the cause of all penetrating abdominal traumas. Peritoneal stimulation symptoms were observed in 56.5% of penetrating abdominal traumas and 62.2% of blunt abdominal traumas. Hypotension was observed in 21.7% of patients with penetrating abdominal trauma compared with 62.2% in patients with blunt abdominal trauma. The most prevalent damaged organ in patients with blunt trauma was spleen (51.4%). The most prevalent damaged intraabdominal organ was small bowel (17.4%). Negative laparotomy was significantly higher in patients with penetrating trauma than those with blunt trauma (p<0.0001). Moreover, 9.2% of all patients had died and mortality rate was higher in patients with blunt trauma than penetrating trauma (p<0.05) .
Conclusion: The results of this study showed that: 1. Road traffic accident and penetrating object were the most common causes of laparotomy in patients with blunt and penetrating trauma respectively; 2. Spleen and small bowel were the most prevalent damaged organs in blunt and penetrating abdominal trauma respectively and; 3. Young males were at highest risk of abdominal traumas.
