  Background & Objectives: Fat embolism syndrome (FES) is mainly due to the obstruction of blood vessels with fat globules, reached to circulation. FES is associated with traumatic and non traumatic diseases. The prevalence is 2-5% in long-bone fractures. The purpose of this study is to evaluate manifestations, laboratory findings and the diagnosed cases of fat embolism.

 Methods: In this retrospective study all the patient records associated with injury were evaluated and those diagnosed with the traumatic fat embolism were selected. The data including sex, age, type of fracture, clinical and laboratory findings and symptom onset time were collected using a questionnaire. These data were then statistically analyzed.

 Results: 17 out of 1660 patients were found to have fat embolism most of which belonged to middle-aged men. The most common clinical features consisted of: respiratory failure, tachycardia and consciousness level alterations. Fat embolism was mainly associated with tibial and femoral shaft fractures. Low level of Pao₂ (Pao₂<60) is the most reliable laboratory test in this study.

 Conclusion: Fat embolism should be regarded as a threarening factor in patients (especially middle-aged ones) with fractures in long bons of lower limbs. Pao₂ Level of can also be used as a reliable laboratory finding.

 Background & Objectives: Delayd post-traumatic intracranial hemorrhage (DTICH) is a kind of brain hemorrhage which occurs after the first six hours of the head trauma, and is not detected in the initial CT Scan taken from the patient in the first 6 hours after the trauma. As DTICH is one of the most important factors in occurance of secondary brain injuries in patients with head trauma, its early diagnosis and treatment could significantly decrease mortality and morbidity of these patientes. This diagnosis is a contraindication to anti-coagulant therapy. This study was conducted to determine the frequency of factors associated with DTICH incidence.

 Methods: This was a case-control study conducted in Semnan trauma center. In this research all the patients with head trauma who referred to Emdad hospital between 2002 and 2004 were studied and the data about the delayed post-traumatic intracranial hemorraege (20 cases) were included. Then, beside determining the incidence of DTICH in the patients with hemorrhage, some risk factors such as headache, contusion, reduction level of conciousness, skull fracture and impact intensity to the head were compared with a control group (40 cases) who had head trauma without primary or delayed hemorrhage. The groups were age and sex-matched. The data were analyzed using Chi-aquare and computing odds ratio.

 Results: This study showed that the frequency of DTICH was 10.6%. There was a meaningful relationship between DTICH and skull fracture, reduction of conciousness level, contusion and impact intensity. But, there was no meaningful relationship between DTICH and intractable headache.

 Conclusions: The results indicated that cases such as skull fracture, contusion, impact intensity and findings such as the reduction of consciousness in patients with head trauma (with no hemorrhage in the first CT scan), can be the risk factors for DTICH.

 Background & Objectives: Mental retardation is a critical deficiency in cognitive functions, social skills, and adjustment behaviors. About 1 to 2 percent of people are mentally retarded because of various factors. The purpose of this research was to study the prevalence of mental retardation in Ardebil city and determining the role of environmental and Heredity factors on mental retardation. In other words, which of pre-, on-, and post-birth factors as well as environmental factors are related to mental retardation of 7-11 aged children.

 Methods: In order to find out the prevalence of mental retardation, a sample of 500 families were selected by simple random sampling method and were studied by causal-comparative method. Also percentage, frequency, and comparing of two independent groups were used to analyze the data and study the extent of prevalence.

 Results:�The results showed that the rate of prevalence of mental retardation is 3.6%, which is higher than the extent of prevalence of the world. Also the results of comparing two groups normal and mentally retarded revealed that familial marriages, in-birth events, fever and convulsion diseases during post-birth period are higher in mentally retarded group. Furthermore, the results showed that the level of mothers’ educations in normal group is significantly higher than that of mentally retarded group. And among the other factors, environmental factors were the most important factors of mental retardation of children in Ardabil city.

 Conclusion:�The high rate of prevalence of mental retardation and the role of environmental factors in mental retardation of children in Ardabil city require environmental intervention such as training of families and improving health level of society.

Background & Objectives: Serious reactions which normally is delayed and occur against serious stressor factors like natural disasters (for example: earth quake, flood and etc) and human made disasters (for example war, murder and etc) calls post traumatic stress disorder (PTSD). The aim of this study was Assessing the effectiveness of teaching problem solving skills in decreasing the symptoms of PTSD.

Methods:�The type of this research is experimental. After clinical assessment and selecting with clinical assessment these individuals showed PTSD symptoms through the results of both Mississippi scale and clinical appointment, in which there were 160 cases. The cases were separated to two groups of experimental and control. Through an experimental method, we studied and measured changes of their status before and after examination and only case group had been chosen for problem solving skills teaching. In order to analyze the results of the study, a T test and Variance analysis (ANOVA) were used.

Results: The results showed that 61.6 percent of population showed PTSD symptoms and there was no significant difference between male and female in level of PTSD symptoms. There was a  significant difference between, means level of PTSD in pre-test and post-test conditions, in addition there was no significant difference between levels of PTSD symptoms-decreasing, in female group after intervention, and male group. By comparing mean numbers of samples, in pre-test and post-test results of control and experiment groups in using problem-focused coping skills and decreasing emotion-focused coping skills, there was a significant differences. Also there was not any difference in using levels of coping methods, but indeed in amount of using emotion-focused coping method there was significant difference between male and female.

Conclusion: Presence of significant differences between pre-test and post-test results showed that training problem-solving-skills in decreasing PTSD symptoms is effective.

  Background and objectives: The most common cause of death in the people (1-44 years old) is trauma and it ranks third as the cause of death in all ages. Road and city accidents with motor vehicles and its effects consist 50% of trauma cases. The mortality rate in traffic accident shows the depth of traffic event, but in any way most of the victims can be saved and we can prevent many of these accidents. The accident is of greater importance in especially developing countries like our country, because in addition to losing a great number of active economic and social power, it causes damage in the corpus of the community, in a way that these accidents cost more than 3% of country in gross productions.

  Methods: This investigation which is considered as a descriptive study is in order to do an epidemiologic investigation of accidents that have led to death in Ardabil Province from Farvardin 2002 to Farvardin 2003 through collected data from Ardabil’s legal medicine center and was analyzed through SPSS.

  Results: The analysis of collected data consisted of 272 cases of events, shows that most of them are male (82%) and they are 21-30 years old. The existence of inversed relation ship with educational level and mortality rate was one of the other findings. Also it became clear that most of the vehicles were small vehicles (70.6%) and most of the victims were pedestrians (34%). Accidents rate in road was 63.6% and accidents in the cities 36.4%, and most of them have happened in summer (38.2%). Most of the mortalities took place in the first minutes and at the same place of accident (50%) and mortality cause of most people was multiple traumas (48.5%) and Brain injuries (46.6%).

  Conclusion: Factors influencing the rate of death in accidents are as followings: male, age (21-30), low education level, summer, and small vehicles. The main causes of death in accidents are multiple trauma and head injuries.

  Background and objective: Injuries account for 16% of global burden of diseases and causes a great deal of mortality and morbidity. Today, amputation is one of the biggest challenges facing us and may accompany serious functional, psychosocial and personality disorders in communities. Therefore, we decided to assess the causes and types of traumatic amputation in patients referring Ardabil’s Fatemi Educational Hospital from 2005 through 2006.

  Methods and materials: The present study was descriptively & analytically) retrospective in which the data were collected using a questionnaire. Our study population included 218 cases referring Ardabil Fatima educational Hospital for amputation from the beginning of 2005 through the end of 2006.

  Results: In this study, the mean age of injured cases is 28.9±19.1 and men were also injured three times more than women. Most of the cases attended in summer between 8:00 Am -8:00 Pm. The number of cases among city dwellers and residents of rural areas were almost equal and most of the cases (39/6%) were illiterate. Most of the cases were injured outdoors especially in their workplace. The most commonly seen cause of amputation was tools used in farming and husbandry especially mower. Most of the amputations (50/5%) were total and unintentional (99.5%). Most of the injuries were seen in upper extremities (94.5%), hands and especially fingers (97%)�

  conclusion: Based on the obtained results, male workers are at a higher risk. Most of the injuries occurred during the work hours and amputation caused by tools used in farming and husbandry has a high prevalence. This is probably due to the unsafe and old structure of these tools.

  Background & Objective: Perineal trauma usually occurs during childbirth and associates with short and long term complications for women. B lood loss, urinary, faecal and sexual incontinence are effects of after childbirth complications of perinal trauma. These can cause maternal and newborn morbidity. This study wanted to compare the effectiveness of two techniques for perineum protection " hands off" versus "hands on"(Ritgen) during childbirhtfrom view points of frequency, degree and suture of perineal trauma .

  Methods: This r andomized clinicaltrial study carried out on 70 nulliparous women thatexpecting normal birth of a singleton . They were randomly selected and divided in hands offand hands on (N = 35) groups. In the 'hands on' method, midwife put pressure on the baby's head and support ('guard') the perineum then lateral flexion is used to facilitate delivery of the shoulders, and in the 'hands off' method, midwife keep her hands poised, not touching the head or perineum, allowing spontaneous delivery of the shoulders . We analyzed data with descriptive statistical methods, t-test, chi-squer, mann whitney and non parametric tests by SPSS.

  Results: Rates of intact perineum was significantly higher in the 'hands off' group (50%, 40%, p = 0.48). The f irst and seconddegree tears were significantly lower in the 'hands off' group (40.6%, 50%, vs, 9.4%, 10%, p = 0.48). We did not observe any significant differences in the rate of lacerations in the anterior regions of the perineum and frequency of suture between the two groups

  Conclusions: The hands off technique in the second stage of�labour increases the likelihood of an intact perineum.

  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.

Background & objectives: Brain trauma is one of the most common causes of damage to the central nervous system which can lead to death and long-term disability. The present study aimed at investigating the effect of 8 weeks of swimming exercise on the level of memory and interleukin 10 (IL-10) in the hippocampus and prefrontal cortex of mice with brain trauma.
Methods: 40 male NMRI mice were randomly divided into four groups (control, swimming, trauma, swimming + trauma). After completing the exercise protocol, induction of trauma was performed by the weight -drop method. Ten days after trauma induction, the mice were evaluated for spatial memory with Y-maze test. The IL- 10 level was measured using ELISA technique. One-way analysis of variance and Tukey post hoc test were used for statistical analysis at a significance level of p<0.05 and using SPSS software version 26.
Results: The study results indicated that eight weeks of swimming exercise significantly increase memory in mice with brain trauma (p=0.001). Furthermore, eight weeks of swimming exercise significantly increase the level of IL-10 in the hippocampus of mice with brain trauma (p=0.001). However, this increase was not significant in the prefrontal cortex (p=0.126).
Conclusion: The results of the present study showed that swimming exercise before induction of brain trauma reduces inflammation and memory disorders and facilitates recovery after injury. Previous exercise training can probably reduce inflammation by increasing the amount of anti-inflammatory cytokines, including interleukin-10, and limit secondary damage with its protective effect.

Background & objectives: Dental anxiety is an effective factor in reducing children's dental visits. It is necessary to identify the factors involved in causing dental anxiety to promote public health. The purpose of this study was to evaluate the relationship between dental fear and anxiety in 5-10 -year -old children with dental caries and a history of trauma in Ardabil dental clinics in 2022.
Methods: 247 children (139 girls and 108 boys) were examined in terms of demographic information, history of oral and dental trauma, and socio-economic status through a questionnaire. The dmft/DMFT index was determined using the clinical examination to check the oral health condition. Dental fear and anxiety were measured using two standard scales, FIS and CFSS-DS. Chi-square test was used for data analysis .
Results: According to the FIS index, the prevalence of dental anxiety was 11.4% and according to the CFSS-DS questionnaire, it was 18.2%. Children aged 5-7 years showed more anxiety (p=0.043). Children who had a dental visit showed higher levels of anxiety based on the CFSS-DS index (p=0.002). According to the FIS index, children without a dental visit history had a higher frequency in the "very upset" group (p=0.009). Severe dental caries in permanent teeth (DMFT) were associated with a higher level of anxiety (p=0.028). No statistically significant relationship was found between gender, number of siblings, child's position in the family, parent’s education, family income level, history of trauma and dmft with dental anxiety.
Conclusion: The results of the present study showed that age, history of dental visits and decay of permanent teeth are effective factors on children's dental anxiety.
