The Feasibility of Dual-Energy Computed Tomography in Cardiac Contusion Imaging for Mildest Blunt Cardiac Injury.

PURPOSE: The purpose of this study was to evaluate the efficiency and feasibility of dual-energy computed tomography (DECT) used in the diagnosis of cardiac contusion with the mildest blunt cardiac injury. MATERIAL AND METHODS: This study was performed between February 2014 and September 2015; a total of 17 consecutive patients (10 men and 7 women; median age, 51 years [range: 20-78]) were enrolled in the study. The DECT was performed within 48 hours of the trauma and a subsequent follow-up DECT was performed a little less than 1 year after the first examination. All examinations were analyzed on iodine map images by 2 experienced radiologists. Interobserver and intraobserver agreement was calculated. The correlation of initial troponin level, age, and sex with number of contusion areas in the left ventricle and complete recovery of contusion were measured. RESULTS: The contusion areas were amorphous, with considerable variation in their size, shape, and density. Contusions were primarily located in the left free wall of the ventricle, the ventricular septum, and the apex, respectively. In 10 patients, contusion areas disappeared on follow-up examination. In 4 patients, the contusion areas decreased but were still present in the follow-up examination. The interobserver agreements were almost perfect with respect to the presence of cardiac contusion, the anatomic location of contusions, and the contusion areas (kappa values of 1.0, 1.0, and 0.9 for intraobserver agreement and 1.0, 1.0, and 1.0 for intraobserver agreement, respectively). Correlations were found between age of patients and complete recovery of contusion (P = 0.01). CONCLUSIONS: Dual-energy computed tomography can show cardiac contusion and could be useful and feasible for the diagnosis and follow-up of blunt cardiac injuries. Dual-energy computed tomography is a new, user-independent, and valuable imaging technique.

Analyses of demographical and injury characteristics of adult and pediatric patients injured in Syrian civil war.

PURPOSE: Aimed to analyze demographical data and injury characteristics of patients who were injured in the Syrian Civil War (SCW) and to define differences in injury characteristics between adult and pediatric patients. METHODOLOGY: Patients who were injured in the SCW and transferred to our emergency department were retrospectively analyzed in this study during the 15-month period between July 2013 and October 2014. RESULTS: During the study period, 1591 patients who were the victims of the SCW and admitted to our emergency department due to war injury enrolled in the study. Of these patients, 285 were children (18%). The median of the injury severity score was 16 (interquartile range [IQR]: 9-25) in all patients. The most frequent mechanism of injury was blunt trauma (899 cases, 55%), and the most frequently-injured region of the body was the head (676 cases, 42.5%). Head injury rates among the children's group were higher than those of the adult group (P < .001). In contrast, injury rates for the abdomen and extremities in the children's group were lower than those in the adult group (P < .001, P < .001). CONCLUSION: The majority of patients were adults, and the most frequent mechanism of injury was blunt trauma. Similarly, the children were substantially affected by war. Although the injury severity score values and mortality rates of the child and adult groups were similar, it was determined that the number of head injuries was higher, but the number of abdomen and extremity injuries was lower in the children's group than in the adult group.

Is this a simple drug eruption to be discharged?

'Erythema Multiforme associated with Phenytoin And Cranial radiation Therapy' (EMPACT) is a very rare clinic situation and classified in EM-like drug reactions. It can be easily misdiagnosed as acute urticaria or drug eruption in ED. Initial symptoms may resemble a simple skin problem, but diagnosing and early hospitalization of the patients can be lifesaving. Here, we present a man with renal cell cancer and brain metastases who admitted to ED due to fever and generalized rash. His skin lesions beginning from his head and spreading through the torso appeared four days after the end of radiotherapy (11 days after the initial dose of both radiation and oral phenytoin). Inspection showed erythematous lesions on the scalp, neck, torso and arms. These lesions had desquomative character on the scalp. Erythematous maculopapular lesions with the tendency of fusion were also visible on the chest, abdomen, back, on the flexor areas of the arm, forearm and femoral region. Laboratory studies showed normal complete blood counts, high creatinine kinase, creatinine kinase-MB, gamma-glutamyl transpeptidase, aspartate aminotransferase, lactate dehydrogenase, albumin and total protein. After discontinuation of phenytoin and giving H1, H2 receptor blockers and steroid intravenously, he was discharged two weeks later with full recovery.

Characteristics of Patients Who Admitted to the Emergency Department Because of Burns Due to Dens Liquids Such as Hot Milk/Oil.

OBJECTIVE: Burn is the tissue damage on body caused due to various reasons. Although all burns caused by hot liquids are investigated as scalding burns, dense liquid burns (DLB) caused by such as milk and oil are different from other burns. The aim of this study was to report the properties of DLB. MATERIALS AND METHODS: Patients admitted to the Emergency Service of Atatürk University Hospital, with DLB from June 2003 to December 2008, were examined retrospectively. RESULTS: During the study, 28 DLB patients were admitted to the emergency service. The most common admission were found in autumn 28.6% (n=8), and in May and June, 17.9% (n=5). The frequency of burns on the right upper extremity was seen in 50% (n=14) of the patients. The burn degree of all patients was determined as 2(nd) degree. Seventy-five percent (n=21) of the patients were discharged, 14.3% (n=4) were hospitalized. None of the patients died. CONCLUSION: Dense liquid burns is a burn type that is commonly seen in women, absolutely causing 2(nd) degree burns, frequently reported in upper extremity and head/neck regions, and in contrast to other studies, in our region it is completely seen in patients living in city centre.

The Evaluation of Serum Copeptin Levels and Some Commonly Seen Thrombophilic Mutation Prevalence in Acute Pulmonary Embolism.

Acute pulmonary embolism (PE) is a common, emergent condition and may affect a large number of patients. Copeptin has been indicated to be a sensitive biomarker of arginine vasopressin release, and has diagnostic and prognostic value in various clinical conditions. Genetic mutations are considerable components of thrombophilic diseases, and factor II gene G20210A, (FII20210A), factor V Leiden (FVL, G1691A) and methylenetetrahydrofolate reductase gene C677T (MTHFR677T) single nucleotide polymorphisms are the most common mutations of thrombophilic diseases. In this study, serum copeptin levels were determined in patients with PE and healthy controls, and the results were discussed. The prevalence of some commonly seen thrombophilic mutations was also evaluated in patients with PE. The study included 32 patients (18 male, 14 female) with PE and 24 (13 male, 11 female) age- and gender-matched healthy controls. A significant difference in serum copeptin levels was determined between the patient and control groups (8.58 ± 4.42 and 4.07 ± 1.02 pmol/L, respectively). Heterozygous mutant genotype for FII20210A and heterozygous mutant genotype for FVL were observed in 3.1 and 9.4% of patients, respectively. Mutant genotype of 49% was determined for MTHFR677T mutations. It was concluded that copeptin may have diagnostic value for PE.

Rare and Severe Maxillofacial Injury Due to Tear Gas Capsules: Report of Three Cases.

Tear gases are used by police or armed forces for control of riots or social events or by the general population for private self-defense. These agents are used widely throughout the world, but some harmful effects have reported. In addition, despite well-defined chemical side effects documented in the literature, data are insufficient regarding mechanical injury due to tear gas capsules. We report three cases of severe maxillofacial injury in patients who had these capsules fired from tear gas guns directly to their faces. The capsules penetrated the patients' faces, causing potentially fatal injuries. To our knowledge, reports of this kind of injury related to tear gas capsules are very rare in the literature. In conclusion, tear gas guns may be very dangerous in terms of human health and they may cause severe injuries, especially when they are not used according to strict guidelines.

The utility of cardiac magnetic resonance imaging in Kounis syndrome.

INTRODUCTION: Current diagnostic measurements used to assess myocardial involvement in Kounis syndrome, such as electrocardiography (ECG), cardiac enzymes, and troponin levels, are relatively insensitive to small but potentially significant functional change. According to our review of the literature, there has been no study using magnetic resonance imaging (MRI) on Kounis syndrome except for one case report. AIM: To identify the findings of dynamic contrast-enhanced magnetic resonance imaging (CE-MRI) in patients with Kounis syndrome (KS) type 1. MATERIAL AND METHODS: We studied 26 patients (35 ±11.5 years, 53.8% male) with known or suspected KS type 1. The patients underwent precontrast, first-pass, and delayed enhancement cardiac MRI (DE-MRI). Contrast enhancement patterns, edema, hypokinesia, and localization for myocardial lesions were evaluated in all KS type 1 patients. RESULTS: Contrast-enhanced magnetic resonance imaging demonstrated an early-phase subendocardial contrast defect, and T2-weighted images showed high-signal intensity consistent with edema in lesion areas. None of the lesion areas was found upon contrast enhancement on DE-MRI. The area of early-phase subendocardial contrast defect was reported as follows: the interventricular septum in 14 (53.8%) patients, the left ventricular lateral wall in 8 (30.7%), and the left ventricular apex in 4 (15.4%). CONCLUSIONS: Dynamic cardiac MR imaging is a reliable tool for assessing cardiac involvement in Kounis syndrome. Delayed contrast-enhanced images show normal washout in the subendocardial lesion area in patients with Kounis syndrome type 1.

The significance of routine thoracic computed tomography in patients with blunt chest trauma.

PURPOSE: The purpose of this study is to investigate whether the use of thoracic computed tomography (TCT) as part of nonselective computed tomography (CT) guidelines is superior to selective CT during the diagnosis of blunt chest trauma. SUBJECTS AND METHODS: This study was planned as a prospective cohort study, and it was conducted at the emergency department between 2013 and 2014. A total of 260 adult patients who did not meet the exclusion criteria were enrolled in the study. All patients were evaluated by an emergency physician, and their primary surveys were completed based on the Advanced Trauma Life Support (ATLS) principles. Based on the initial findings and ATLS recommendations, patients in whom thoracic CT was indicated were determined (selective CT group). Routine CTs were then performed on all patients. RESULTS: Thoracic injuries were found in 97 (37.3%) patients following routine TCT. In 53 (20%) patients, thoracic injuries were found by selective CT. Routine TCT was able to detect chest injury in 44 (16%) patients for whom selective TCT would not otherwise be ordered based on the EP evaluation (nonselective TCT group). Five (2%) patients in this nonselective TCT group required tube thoracostomy, while there was no additional treatment provided for thoracic injuries in the remaining 39 (15%). CONCLUSION: In conclusion, we found that the nonselective TCT method was superior to the selective TCT method in detecting thoracic injuries in patients with blunt trauma. Furthermore, we were able to demonstrate that the nonselective TCT method can change the course of patient management albeit at low rates.

Dual-source computed tomography may define cardiac contusion in patients with blunt chest trauma in ED.

We report a 20-year-old woman with blunt chest trauma because of a motor vehicle injury who has traumatic asphyxia and hypotension. The diagnosis of blunt cardiac injury was put by using dual-energy computed tomography in the emergency department because other laboratory and imaging modalities were useless. After hospitalization in intensive care unit, she was treated with supportive and antiedema therapy. The patient was extubated on the fifth day and discharged on the ninth day without any sequel. Coexistence of traumatic asphyxia with blunt cardiac injury is rare. Several imaging techniques such as transthoracic and transesophageal echocardiography, contrast-enhanced multislice thorax computed tomography or initial electrocardiogram, and troponin I levels are used to detect the myocardial damage, but diagnostic capability is low. Dual-energy computed tomography is a promising new technology with the ability of defining blunt cardiac injuries and may have an indication in the emergency setting in patients with hemodynamic instability to rule in traumatic cardiac complications especially when electrocardiogram and transthoracic echocardiography are useless in the emergency department.

Spinal intradural hematoma and permanent paraparesis after a lumboperitoneal shunt operation: an unusual complication.

Pseudotumor cerebri is a condition of increased intracranial pressure in the absence of clinical, laboratory or radiological pathology. Spinal intradural hematoma formation after lumboperitoneal shunt (LPS) implantation is very rare, but it can cause sudden and serious deterioration. In this report, we present a patient who developed an intradural hematoma following LPS operation. A 27-year-old male patient suffering from headaches and progressive vision loss was diagnosed with pseudotumor cerebri. He underwent LPS operation in January 2009. Four hours after the operation, he developed urinary and fecal incontinence with paraparesis (1/5). Lumbar magnetic resonance imaging identified an intradural hematoma at the level of L2-L3, and he was reoperated. The intradural hematoma was removed. Physical therapy was started because of paraparesis. Two months later, the patient's muscle strength had increased to 3/5. Surgeons must remember that, LPS implantation can cause a spinal intradural hematoma in a small percentage of patients, with catastrophic results.

Predictors of mortality in childhood burns: an 8-year review.

This study aims to analyze the epidemiological characteristics and predictors of mortality from burn injuries in childhood patients admitted to our hospital during an eight-year period. The medical records of acute childhood burn patients were reviewed retrospectively. All variables thought to be associated with mortality were entered in a multiple binary logistic regression model (method = stepwise). The magnitude of risk was measured by the odds ratio, and the 95% confidence interval was estimated. A total of 2269 acute childhood burn patients were admitted during the study period. A total of 86 (3.8%) children died due to burn injuries. Deaths were seen 1.849 times more in males than in females. According to the 1%-10% total body surface area (TBSA) burned group, mortality occurred 121.116 times more in the >41% TBSA burned group. Most burn injuries can be avoided by keeping children away from hazardous and dangerous environments. Also, requiring a multidisciplinary management in these patients, quality of care services given by physicians and nurses certainly will create a positive impact on patients' outcomes.

Patient-staff safety applications: the evaluation of blue code reports.

OBJECTIVE: Blue code systems (BCS) are communication systems that ensure the most rapid and effective resuscitation when a patient is in respiratory or cardiac arrest. A hospital employee faced with the situation of a cardiopulmonary arrest (CPA) starts the system by dialing 6666 from any phone in the hospital. We created a five-person team that includes a doctor, nurse, anesthesia technician, stretcher officer and security guard. The purpose of this study is to share our experiences in initiating the use of the BCS in our hospital. MATERIALS AND METHODS: In our hospital, the records of calls that were made by Callvision BCS were analyzed retrospectively from May 2010 to the end of January 2011. RESULTS: A total of 474 calls were made using the blue code system. Of those calls, 402 (84.5%) were determined to be inappropriate calls. The remaining 72 calls were responded to. Of the 72 patients who were treated, 21 were discharged after they were hospitalized in the service or intensive care unit, 45 cases resulted in exitus, and 5 cases were referred to the Ataturk University faculty of medicine. CONCLUSION: The BCS has achieved its goal. The discharge rate of 29.5% that we achieved is a successful result.

A fatal folk remedy: rope wrapping to the back.

BACKGROUND: Despite the developments in medicine in recent years, people in many regions of the world still tend to use alternative, or non-medical, folkloric treatment methods for many different health problems. One of these methods is "rope wrapping to the back," which is considered to be therapeutic for patients with lumbar disc hernias or low back pain. This method is practiced by local individuals without medical training. CASE REPORT: Over the course of 3 years, 14 patients, 8 women and 6 men, presented to Atatürk University and Erzurum state hospitals in eastern Turkey after undergoing the folk treatment known as "rope wrapping to the back" for low back pain. One of the patients, who had symptoms of systemic infection, later died. Of the other patients, 4 had local infections, 6 had unresolved complaints, and 3 had other complaints. Nine of the patients were treated in the emergency department and 4 required surgery. Two case reports are provided as examples. CONCLUSION: Improvements are needed to increase the accessibility of health care, improve physician-patient communication, and provide information to people, so as to prevent the use of folk remedies, which can have serious complications, sometimes resulting in death.

The role of ischemic neurodegeneration of the nodose ganglia on cardiac arrest after subarachnoid hemorrhage: an experimental study.

BACKGROUND: The heart is innervated by several systems that contribute to the control of the heart's rhythm. The cardiac fibers of the vagus nerve have an important role in the regulation of heart rhythm under many emotional and physical conditions. Severe electrocardiographic disturbances have been reported following subarachnoid hemorrhage (SAH), but ischemic neuronal degeneration of the nodose ganglion of the vagus nerve has not been previously investigated. We examined if there is a relationship between ischemic injury of the nodose ganglion of the vagus nerve and the severity of heart rhythm disorders after subarachnoid hemorrhage. METHODS: This study was conducted on 20 rabbits. Four rabbits were used as a baseline group. Experimental subarachnoid hemorrhage was applied to half of the remaining animals (n = 8) by injecting homologous blood into the cisterna magna, and the others (SHAM group, n = 8) were injected with isotonic saline solution in the same manner. For 20 days after the injection, heart rhythm changes were observed daily. After the experiment, normal and ischemic neuron densities in the nodose ganglia of the vagus nerves were examined stereologically. The number of heart rhythm irregularities and the number of degenerated neurons in the nodose ganglia were compared statistically. RESULTS: The normal heart rhythm rate was 280 ± 45/min. At the beginning of the SAH, the average heart rate was 220 ± 30/min; about 10 hours later, it decreased to 189 ± 30/min, indicating severe bradycardia. However, after 7 days, the average heart rate had increased to 350 ± 30/min. Six animals died due to irregularities in cardiac function and respiration. Histopathological examinations showed that the average density of normal neurons in the nodose ganglion was 10,500 ± 2500 in the baseline animals and the SHAM group, but the normal neuron density was 8250 ± 1500 in survivors and 6450 ± 1330 in dead animals. The ischemic neuronal degeneration in the nodose ganglia was more severe in the dead animals than in the survivors (p < 0.0001). CONCLUSION: Afferent vagus nerves originating from the nodose ganglia have an important role in regulating heart rhythm via their afferent fibers and efferent connections. If neurons of the nodose ganglia are lesioned due to ischemic insult during subarachnoid hemorrhage, heart rhythm regulation by vagus afferent reflexes is disturbed. Vagus pathway paralysis may result in indirect sympathetic overactivity. The development of tachycardia causes depletion of the heart's reserves, and cardiac arrest may be inevitable following extensive subarachnoid hemorrhage.

Acute abdomen associated with organophosphate poisoning.

BACKGROUND: Pesticides are extensively used in developed and developing countries. OBJECTIVES: The present study was designed to evaluate the clinical course of patients with carbamate or organophosphate poisoning presenting to a University-based emergency department (ED). METHODS: All consecutive patients admitted to our ED due to intoxication with carbamate or organophosphate compounds over a 2-year period were enrolled prospectively. RESULTS: A total of 49 consecutive patients (26 females) were diagnosed with carbamate or organophosphate poisoning in the 24-month study period. The mean age of the patients was 32±13.1 years (range 16-70 years). Signs and symptoms most frequently noted in patients with organophosphate or carbamate poisoning were perspiration, vomiting, and bronchorrhea. Abdominal pain was reported by 65.3% of the patients. Abdominal ultrasonography was performed in 22 patients who complained of abdominal pain as a leading symptom. Among these, 63.6% were found to have abdominal free fluid. Pancreatitis and peritonitis developed in one case. Atropine treatment was administered for approximately 24-36h, with a mean total dose of 13.75±6.75mg. Pralidoxime was administered to 70.9% of patients with organophosphate poisoning, but was not used in patients intoxicated with carbamates. Endotracheal intubation and mechanical ventilatory support were required in 14.2% of the patients. Mean duration of mechanical ventilation was 3.7±2.2 days. The overall mortality rate was 10.2%. CONCLUSION: Patients with a diagnosis of organophosphate poisoning should be screened for acute abdomen. The findings in our study suggest that these patients should undergo routine abdominal ultrasonography, especially in cases with abdominal pain along with other abdominal complaints.

Neuropsychiatric disorders and risk factors in carbon monoxide intoxication.

Neuropsychiatric sequelae may be observed in the late phases of carbon monoxide (CO) intoxication. Establishing a link between CO-related neuropsychiatric disorders and associated risk factors may decrease morbidity and mortality by means of appropriate treatment and counseling. The aim of the present study was to determine the relationship between neuropsychiatric outcomes of CO intoxication and demographic and clinical variables. Thirty patients who presented with CO intoxication and had no known neuropsychiatric disease, and 30 healthy controls were included. Physical examinations and laboratory tests were performed. Following the 1st therapy, they underwent mental and psychiatric tests 5 times (the time of discharge, during the 1st week, and during the 1st, 3rd, and 6th months). They underwent cerebral magnetic resonance imaging (MRI) at the end of the 1st month. They were evaluated by cognitive function tests at the 6th month. Lesions relevant to CO intoxication were detected in 46.7% of the patients via cranial computed tomography and in 13.3% via MRI. Evaluation of psychiatric tests revealed a clear decrease in cognitive functions, such as immediate memory, learning, reaching the criterion, spontaneous recall, attention, visual memory, and logical memory. It was found that the patients had anxiety within the 1st month, and the frequency of anxiety reached to the value of the control group by the end of the 6th month. In conclusion, we suggested that CO intoxication might lead to neuropsychiatric disorders. Our results emphasized that in addition to standard treatment, neuropsychiatric evaluation should also be performed in patients with CO intoxication.
