Violence against emergency department employees and the attitude of employees towards violence.

INTRODUCTION: This study was conducted to evaluate the occurrence of violent incidents in the workplace among the various professional groups working in the emergency department. We characterised the types of violence encountered by different occupation groups and the attitude of individuals working in different capacities. METHODS: This cross-sectional study included 323 people representing various professional groups working in two distinct emergency departments in Turkey. The participants were asked to complete questionnaires prepared in advance by the researchers. The data were analysed using the Statistical Package for the Social Sciences (Windows version 15.0). RESULTS: A total of 323 subjects including 189 (58.5%) men and 134 (41.5%) women participated in the study. Their mean (± standard deviation) age was 31.5 ± 6.5 years and 32.0 ± 6.9 years, respectively. In all, 74.0% of participants had been subjected to verbal or physical violence at any point since starting employment in a medical profession. Moreover, 50.2% of participants stated that they had been subjected to violence for more than 5 times. Among those who reported being subjected to violence, 42.7% had formally reported the incident(s). Besides, 74.3% of participants did not enjoy their profession, did not want to work in the emergency department, or would prefer employment in a non-health care field after being subjected to violence. According to the study participants, the most common cause of violence was the attitude of patients or their family members (28.7%). In addition, 79.6% (n=257) of participants stated that they did not have adequate safety protection in their working area. According to the study participants, there is a need for legal regulations to effectively deter violence and increased safety measures designed to reduce the incidence of violence in the emergency department. CONCLUSION: Violence against employees in the emergency department is a widespread problem. This situation has a strong negative effect on employee satisfaction and work performance. In order to reduce the incidence of violence in the emergency department, both patients and their families should be better informed so they have realistic expectations as an emergency patient, deterrent legal regulations should be put in place, and increased efforts should be made to provide enhanced security for emergency department personnel. These measures will reduce workplace violence and the stress experienced by emergency workers. We expect this to have a positive impact on emergency health care service delivery.

BNP shows myocardial injury earlier than Troponin-I in experimental carbon monoxide poisoning.

OBJECTIVE: In this study, our purpose was to determine whether plasma BNP level can be useful or not in determining the severity of myocardial injury formed by CO poisoning and to compare plasma BNP level with serum cTnI level. MATERIALS AND METHODS: In the study, 46 female Wistar Albino rats were used. Rats were divided into four groups, one control group and three poisoning groups. The mixture of pure CO and air was injected for 60 minutes to provide 3000 ppm CO concentration. Blood samples of groups were collected to measure COHb, BNP and cTnI levels. Blood samples of poisoning groups were collected at the 1st, 6th and 12th hours after poisoning. After biochemical procedures, findings were analysed statistically and compared with each other. RESULTS: Eight rats which died in poisoning groups were excluded and 38 rats were evaluated. BNP levels were high in all poisoning groups compared to control group and the difference between them was statistically significant (p < 0.05). cTnI levels were high in 6th and 12th hours poisoning groups compared to control and 1st hour group but only 12th hour group had statistically significant difference (p < 0.05). A statistically positive relation was established between BNP and cTnI levels in 6th and 12th hour groups (R: 0.76 - p < 0.05 - n:38). CONCLUSIONS: It was found that BNP levels increased earlier than cTnI levels in acute severe CO poisoning. BNP levels of the cases which were determined to have increased cTnI levels showing myocardial injury increased as well. BNP can show myocardial injury and its severity in acute CO poisoning.

Therapeutic effect of magnesium sulphate on carbon monoxide toxicity-mediated brain lipid peroxidation.

BACKGROUND: Carbon monoxide (CO) toxicity primarily results from cellular hypoxia caused by impedance of oxygen delivery. Studies show that CO may cause brain lipid peroxidation and leukocyte-mediated inflammatory changes in the brain. AIM: The aim of this study was to investigate whether magnesium sulphate could prevent or diminish brain lipid peroxidation caused by carbon monoxide toxicity in rats. MATERIALS AND METHODS: Fourty rats were divided into five groups of 8 rats each. Group l was not received any agent during the experiment. Group 2 was inhaled CO gas followed by intraperitoneally normal saline 30 minutes (min) later. Group 3 was inhaled CO gas followed by 100 mg/kg magnesium sulphate intraperitoneally 30 min later. Group 2 and Group 3 rats was undergone laparotomy and craniotomy while still under anesthesia at 6 hour, and tissue sample was obtained from the cerebrum. Group 4 was inhaled CO gas followed by intraperitoneally normal saline 30 min later. Group 5 was inhaled CO gas followed by 100 mg/kg magnesium sulphate intraperitoneally 30 min later. Group 4 and Group 5 rats was undergone laparotomy and craniotomy while still under anesthesia at 24 hour, and tissue sample was obtained from the cerebrum. RESULTS: Nitric oxide levels were no significantly different between all groups. Malonyldialdehyde levels increased in intoxication group (group 2) and decreased in treatment group (group 3). Activities of superoxide dismutase decreased in intoxication group (group 2) and increased in treatment group (group 3). Activities of catalase increased in intoxication group (group 2) and decreased in treatment group (group 3). Activities of glutathione peroxidase (GSH-Px) decreased in intoxication group (group 4) and increased in treatment group (group 5). CONCLUSIONS: CO poisoning caused significant damage, detected within the first 6 hours. Due to antioxidant enzymes, especially GSH-Px activity reaching the top level within 24th hours, significant oxidative damage was not observed. The protective effect against oxidative damage of magnesium sulfate has been identified within the first 6 hours.

Investigation of the course of GFAP in blood in the initial 24 hours in rats subjected to minor head trauma.

AIM: Aim of this study is to evaluate the diagnostic efficacy of Glial Fibrillar Acidic Protein (GFAP) particularly in minor head traumas. MATERIALS AND METHODS: 72 female and male, 3 month-old, Sprague Dawley rats were used in the study. The rats were divided into 9 groups. Following anesthesia, all rats were placed in prone position. A 10 mm long and 3 mm thick stainless steel metal disc was fixed onto the skull using dental paste in order to sustain a closed head trauma and evenly distribute the weight throughout the skull. After placing it under the metallic pipe arrangement over a height of 80 centimeters and fixing to make it constant, 50 g metallic discs were released by free fall, and the head trauma was sustained thanks to the gravity-generated force. Blood samples were collected from the rats under anesthesia for biochemical GFAP analysis 10 minutes after the trauma and in 1, 2, 3, 4, 5, 6 and 24 consecutive hours later. RESULTS: GFAP has a peak, and its peak level at hours 1 and 2 in rats subjected to a minor head trauma, with a slight decrease afterwards. CONCLUSIONS: GFAP is an important marker in determining the severity of traumatic brain injury.

Two cases of acute endosulfan toxicity.

BACKGROUND: Endosulfan is widely used in insect control and is absorbed by both humans and animals through the intestinal tract, the lungs, and the skin. Organochlorine insecticides are highly toxic compounds that are responsible for a number of severe intoxications worldwide, with several deaths. A 9-year analysis by one of Turkey's poison control centers reported that pesticide intoxications accounted for 8.8% of 25,572 poisoning calls, with 80.3% of them relating to insecticides and 19.7% concerning rodenticides. CASE REPORTS: We present two cases of unintentional exposure to endosulfan, one of which presented with neurological manifestations, liver toxicity, and required mechanical ventilation and emergent hemodialysis; the other had only neurological manifestations and liver toxicity. CONCLUSION: In cases of endosulfan poisoning, physicians must be aware of neurological manifestations, seizures, and severe metabolic acidosis. If severe metabolic acidosis is present, we suggest that hemodialysis may be an important intervention and should be performed early.

The prognostic importance of trauma scoring systems for blunt thoracic trauma.

BACKGROUND: Early identification and aggressive management of blunt thoracic trauma are essential to reduce the significant rates of morbidity and mortality. The aim of this study was to evaluate the independent predictive value of 5 different trauma scoring systems (Revised Trauma Score [RTS], Trauma and Injury Severity Score [TRISS], Injury Severity Score [ISS], Lung Injury Scale [LIS], and Chest Wall Injury Scale [CWIS]) with respect to prognostic factors such as tube thoracostomy duration, the need for mechanical support and thoracotomy, the length of hospital and ICU stay, morbid conditions, and deaths of patients with blunt thoracic trauma. METHODS: The records of 152 patients with blunt thoracic trauma were reviewed and data consisting of the patients' age and gender, blood pressure and respiratory rate on admission, the extent of chest wall and intrathoracic injury, types of associated injuries, Glasgow Coma Scale (GCS) scores, the need for mechanical support and thoracotomy, tube thoracostomy duration, length of hospital and ICU stay, morbid conditions, and deaths were collected. The relations between the trauma scoring systems and prognostic factors were evaluated by multivariate analysis. RESULTS: The analysis showed that only TRISS was an independent predictor of mortality and only LIS was an independent predictor of morbidity, the need for thoracotomy, and tube thoracostomy duration. TRISS and LIS were independent predictors of the length of ICU stay. ISS, CWIS, and LIS were independent predictors of the need for mechanical support. RTS, TRISS, ISS and LIS were independent predictors of the length of hospital stay. CONCLUSIONS: The LIS grade appeared to correlate with the severity of blunt thoracic injury and was found to be the most useful scoring system in predicting the outcomes of these patients.

Effect of interleukin-10 on pancreatic damage caused by organophosphate poisoning.

Organophosphate poisoning is a common cause of severe morbidity and mortality in emergency departments. Acute pancreatitis is a frequently reported consequence of organophosphate poisoning, but preventing this potentially severe complication has not been the subject of much research. We tested whether interleukin-10, a cytoprotective agent, could prevent or diminish pathological signs of acute pancreatitis caused by organophosphate poisoning. Thirty rats were divided into three equal groups. Group 1 did not receive any agent during the experiment. Group 2 received 0.8 g/kg fenthion intraperitoneally, followed by 6 ml/kg intraperitoneal normal saline 30 min and 3 h later. Group 3 received 0.8 g/kg fenthion intraperitoneally, followed by 2 microg/kg of interleukin-10 intraperitoneally 30 min and 3 h later. All rats underwent laparotomy and thoracotomy while still under anesthesia at 6 h, and tissue samples were obtained from the pancreas. After blood samples were taken by cardiac puncture, the animals were sacrificed. Organophosphate poisoning resulted in significant elevations of serum amylase and glucose. Interleukin-10 significantly reduced pancreatic damage as determined by pathologic scoring, but not by enzyme elevations. Interleukin-10 should be considered for larger studies in other animal models to confirm its ability to decrease pancreatic damage after organophosphate poisoning treatment with interleukin-10.
