The comparison of the efficiency of traditional lectures to video-supported lectures within the training of the Emergency Medicine residents.

OBJECTIVES: Recent developments in computer and video technology, multimedia resources enter quickest way possible into medical education and have started to gain popularity. The aim of this study is to evaluate the impact of video-supported lectures on leaning, with comparison to traditional lectures. METHODS: According to lecture techniques, two separate groups; one is the traditional lectures group (TLG) and the other is video-supported lectures group (VSLG), are formed. While the TLG is offered a traditional lecture the VSLG is offered a video-supported lecture with imbedded videos which are related to the topics in the traditional lecture. Both study groups take pretest and posttest with MCQs (multiple choice questions) and OSCEs (objective structured clinical examination). RESULTS: The study includes 30 volunteer residents in Dokuz Eylul University School of Medicine Department of Emergency Medicine. No difference is observed between TGL and VSLG in pretest and posttest scores (p = 0.949, p = 0.580). And additionally, comparing the scores of both groups, we cannot observe any difference between the pretest OSCE scores of each group (p = 0.300), however posttest OSCE scores shows a dramatic odd in-between (p = 0.010). When pretest MCQs and posttest MCQs mean scores are compared, both tests (TLG, VSLG) has not any significant difference (p=0.949, p = 0.580). Nevertheless, after comparing OSCEs pretest and posttest mean scores, we can see significant difference in mean scores of both (TLG, VSLG), (p = 0.011, p = 0.001). CONCLUSIONS: Taken into consideration, the findings of this study shows possibility of improving educational techniques to acquire clinical skills by using local resources and low-cost technology.

Emergency department visits caused by adverse drug reactions: results of aTurkish university hospital.

BACKGROUND/AIM: We aimed to evaluate adverse drug reaction (ADR)-related emergency department (ED) visits in the ED of the Dokuz Eylül University Hospital prospectively. MATERIALS AND METHODS: Patients who were admitted to the ED during 1-week periods of four different seasons between July 2010 and April 2011 were enrolled. Demographics of patients, previous ADR history, clinical progress, and outcomes were recorded. Causality assessment was done according to World Health Organization Uppsala Monitoring Centre categories. ADRs were categorized as certain, probable, or possible. RESULTS: Patients who were on medications (26.5%, n = 1838) were evaluated for ADR-related ED admissions. ADRs accounted for 5.9% of cases (n = 108). The most frequently affected systems were the gastrointestinal (35.2%, n = 38), dermatological (23.1%, n = 25), and hematological (10.2%, n = 11) systems (7.4%, n = 8). The most common causes of ADRs were antiinfectives (31.6%, n = 33). Amoxicillin, Coumadin, and paracetamol were the most common medications that caused ADRs. CONCLUSION: Nearly 6% of the admissions were ADR-related. ADRs should always be considered when patients who are on medication are admitted to the ED. Multicenter epidemiologic studies are required to know the real rates of ADR cases in EDs in Turkey.

Injury and illness among athletes during a multi-day elite cycling road race.

OBJECTIVES: Although road bicycle races have been held for more than a century, injury and illness patterns during multi-day bicycle events have not been widely studied. The aim of this study was to determine the incidence of injury and illness among riders and describe the medical care interventions provided to participants of cycling road races. METHODS: A prospective observational study was conducted on the Presidential Cycling Tour of Turkey, which was held between April 26 and May 3, 2015. The race lasted 8 days and covered 1258 km of road. There were 166 elite cycling athletes representing 21 teams from various countries. Data collected pertaining to incidents involving injury or illness included the following: type of injury; anatomical location of injury; details of the medical encounter; location of the intervention; treatment provided; medication administered and disposition of the rider. An injury was defined as a physical complaint or observable damage to the body produced by the transfer of energy of the rider. An illness was defined as a physical complaint or presentation not related to injury. RESULTS: The overall incidence (injury and illness) was 5.83 per 1000 cycling hours. (Injury incidence was 2.82 vs illness incidence of 3.01 per 1000 hours cycling). A total of 31 incidents occurred. Of these, 15 were injuries, while 16 were complaints of a non-traumatic nature. A total of 43 interventions were made in the 15 cases of injury. The most commonly injured body regions were limbs; the majority of injuries involved the skin and soft tissue. The most common medical intervention was wound care (64% of all interventions). Two riders had to withdraw from the race, and one was hospitalized due to a traumatic pneumothorax. None of the non-traumatic cases resulted in withdrawal from the race. CONCLUSIONS: A broad spectrum of illness and injury occurs during elite multi-day road races, ranging from simple skin injuries to serious injuries requiring hospital admission. Most injuries and illnesses are minor; however, medical teams must be prepared to treat life-threatening trauma.

Novel biochemical marker for differential diagnosis of seizure: ischemia-modified albumin.

INTRODUCTION: Differential diagnosis of seizure is critical in patients presented to emergency department (ED) with altered mental status or loss of consciousness. Although electroencephalogram is important for the diagnosis of seizures, its use in EDs is limited. The level of ischemia-modified albumin (IMA) increases in conditions of ischemic distress such as acute coronary syndrome, pulmonary embolism, and mesenteric ischemia. No studies exist in literature regarding the increase of IMA levels parallel to increased seizure activity in adults. The aim of the study was to investigate the diagnostic value of IMA in adult patients presented to ED with seizures. METHODS: Forty patients presented to ED with seizure, and 40 control patients of similar age and sex as the study group were enrolled in this study. Initial and fourth-hour levels of IMA and albumin were measured. Groups were compared in terms of sociodemographic data and details regarding their seizures as well as initial and fourth-hour levels of IMA. RESULTS: Mean levels of IMA were 61.5 IU/mL and 18.5 IU/mL (P < .001) initially and 56.7 IU/mL and 15.4 IU/mL (P < .001) at the fourth hour; levels were higher in the study group compared with control group. Ischemia-modified albumin/albumin ratios in study and control groups were 1555.3 IU/g and 462.4 IU/g (P < .001) initially and 1431.4 IU/g and 383.6 IU/g (P < .001) at the fourth hour, respectively. CONCLUSION: Blood IMA level and IMA/albumin ratio significantly increase in adult patients who experienced seizures. Ischemia-modified albumin may be considered as a useful biomarker in the differential diagnosis of seizure.

The comparison of heparinized insulin syringes and safety-engineered blood gas syringes used in arterial blood gas sampling in the ED setting (randomized controlled study).

INTRODUCTION: The arterial blood gas measurement process is a painful and invasive procedure, often uncomfortable for both the patient and the physician. Because the patient-related factors that determine the difficulty of the process cannot be controlled, the physician-related factors and blood gas measurement techniques are a modifiable area of improvement that ought to be considered. Many hospitals use insulin syringes or syringes washed with heparin for the purpose of blood gas measurement because they do not have blood gas-specific syringes. In this prospective cross-sectional study, we aimed to compare safety-engineered blood gas syringes and conventional heparinized syringes used during the arterial blood gas extraction process in terms of ease of operation, the physician-patient satisfaction, laboratory appropriateness, and complications. METHODS: Our study included patients whose arterial blood gas needed to be measured in the emergency department and who agreed to participate in the study. Patients were randomly divided into 2 groups. The arterial blood gas of the patients from the first group was measured by using conventional heparinized syringes, whereas safety-engineered blood gas syringes were used to measure the arterial blood gas of the patients from the second group. The groups were compared in terms of demographic data, the number of attempts, the physician and patient satisfaction, early and late-term complications, and laboratory appropriateness of the taken sample. RESULTS: A total of 550 patients were included in our study in a 2-month study period. There were no significant differences between patients in terms of sex, age, weight, height, body mass index, and wrist circumference. In addition, the number of attempts (P=.489), patients' pain level during the procedure (P=.145), and the degree of difficulty of the procedure according to the patient (P=.109) and physician (P=.554) were not significantly different between the groups. After arterial blood gas extraction procedure, 115 patients (20.9%) developed complications. In the conventional heparinized syringe group, the complication rate (n=69; 25.1%) was significantly higher compared with the group that used safety-engineered blood gas syringes (n=46; 16%; P=.0211). Localized pain, which is one of the most common early complications, was more frequent in the conventional heparinized syringe group (19.3%). Complications in women (P=.003) and local pain (P=.01) developed lesser in the second group that used safety-engineered blood gas syringes, and the patient-physician satisfaction was higher in that group, as well. In the evaluation 48 hours after the procedure, the ratios of infection and local hematoma were higher in the conventional heparinized syringe group (P=.0213 and P < .0001). CONCLUSION: In this study, we did not find any significant differences between the conventional heparinized syringes and safety-engineered blood gas syringes in terms of ease of operation, physician and patient satisfaction, and appropriateness of the taken sample. However, patients whose arterial blood gas was extracted by using safety-engineered blood gas syringes felt less pain and experienced fewer infections and hematomas at their puncture site.

A New Model in Reducing Emergency Department Crowding: The Electronic Blockage System.

OBJECTIVES: Emergency department (ED) crowding is a growing problem across the world. Hospitals need to identify the situation using emergency department crowding scoring systems and to produce appropriate solutions. METHODS: A new program (Electronic Blockage System, EBS) was written supplementary to the Hospital Information System. It was planned that the number of empty beds in the hospital should primarily be used for patients awaiting admission to a hospital bed at the ED. In the presence of patients awaiting admission at the ED, non-urgent admissions to other departments were blocked. ED overcrowded was measured in the period before initiation of EBS, the early post-EBS period and the late post-EBS period, of one-week's duration each, using NEDOCS scoring. RESULTS: NEDOCS values were significantly lower in the early post-EBS period compared to the other periods (p≤0.0001). Although outpatient numbers applying to the ED and existing patient numbers at time of measurement remained unchanged in all three periods, the number of patients awaiting admission in the early post-EBS period was significantly lower than in the pre-EBS and late post-EBS periods (p=0.0001, p=0.001). CONCLUSIONS: EBS is a form of triage system aimed at preventing crowding and ensuring the priority admission of emergency patients over that of polyclinic patients. In hospitals with an insufficient number of total beds it can be used to reduce ED crowding and accelerate admissions to hospital from the ED.

Turkish patient relatives' attitudes towards family-witnessed resuscitation and affecting sociodemographic factors.

BACKGROUND: Witnessed resuscitation is the process of resuscitation in the presence of family members. STUDY OBJECTIVE: Our goal was to determine the attitudes of relatives of the patients presenting to our emergency department regarding witnessed resuscitation and to elucidate the sociodemographic variables affecting their perspectives. METHODS: Blood relatives and spouses of all adult patients presenting to our emergency department in Turkey between 7 January 2005 and 16 January 2005 were included in the study. Accompanying persons other than patients' relatives were excluded. Surveys were conducted using a structured face-to-face interview with the participants. RESULTS: A total of 420 family members were surveyed. Most participants (66.4%) stated that they would like to be present during resuscitation. The most common reason for wanting to be present during cardiopulmonary resuscitation (CPR) was: 'providing support for the patient' and 'witnessing the intervention'. Male family members and family members of patients without health insurance were more likely to want to witness resuscitation. Although prior willingness to witness CPR did not affect the likelihood of wanting to witness CPR, those family members who had previously witnessed CPR ending in death had decreased likelihood of wanting to witness it again. The participants' age, level of education, marital status, presence of chronic illness, and the patients' presenting diagnosis did not significantly affect the rate of willingness to witness CPR. CONCLUSION: Our data locally revealed that most of the participants in this survey would like to witness CPR conducted on their family members who presented to our emergency department.

Comparison of trauma mortality between two hospitals in Turkey to one trauma center in the US.

OBJECTIVES: The development of comprehensive international trauma case registries could be used to perform outcomes analysis and comparisons between countries with the goal of improving trauma care worldwide. METHODS: A retrospective study (April 2004 to April 2005) of injured patients from a Pennsylvania state trauma center (PSTC) were case matched according to age, sex, and injury severity score with two Turkish hospitals. Patients' demographics (age, sex), prehospital information (mechanism of injury, mode of transportation), injury severity (injury severity score and Glasgow coma score), and outcomes (intensive care unit length of stay, hospital length of stay, mortality) were collected. STATISTICAL ANALYSIS: P value of less than 0.05, odds ratio (OR), chi2 test, two-sample t-test, mean+/-SD. RESULTS: Medical records from 506 Turkish trauma patients were abstracted and compared with 506 injured patients in the PSTC registry. Patients in Turkey presented more commonly with a Glasgow coma score of less than or equal to 8 (13.09 vs. 4.26%, P<0.01, OR 3.38) had increased mortality (8.30 vs. 0.79%, P<0.01, OR 11.36) and required mechanical ventilation more than 1 day more often (16.44 vs. 8.75%, P<0.01, OR 2.05). Motor vehicle crashes were the leading cause of injury in both groups. Assaults and falls were more frequent in the PSTC. Pedestrian injuries were more common and had higher mortality rates in Turkey (P<0.05). CONCLUSION: This study demonstrates significantly worse outcomes in trauma care and higher mortality rates in Turkey versus PSTC. Developing a trauma registry to monitor improvements in patient care and to target injury prevention strategies should be a high priority for the Turkish healthcare system.

Clinical efficacy of dexamethasone for acute exudative pharyngitis.

The objective of this study was to investigate whether treatment with single-dose dexamethasone can provide relief of symptoms in acute exudative pharyngitis. A prospective, randomized, double-blinded, placebo-controlled clinical trial was undertaken over a 3-month period in a university-based Emergency Department. The study included all consecutive patients between 18 and 65 years of age presenting with acute exudative pharyngitis, sore throat, odynophagia, or a combination, and with more than two Centor criteria. Each patient was empirically treated with azithromycin and paracetamol for 3 days. The effects of placebo and a fixed single dose (8 mg) of intramuscular injection of dexamethasone were compared. The patients were asked to report the exact time to onset of pain relief and time to complete relief of pain. After completion of the treatment, telephone follow-up regarding the relief of pain was conducted. A total of 103 patients were enrolled. Thirty patients with a history of recent antibiotic use, pregnancy, those who were elderly (>65 years of age) and patients who failed to give informed consent were excluded. Forty-two patients were assigned to the placebo group and 31 were assigned to the intramuscular dexamethasone group (8-mg single dose). Time to perceived onset of pain relief was 8.06+/-4.86 h in steroid-treated patients, as opposed to 19.90+/-9.39 h in the control group (p=0.000). The interval required to become pain-free was 28.97+/-12.00 h in the dexamethasone group, vs. 53.74+/-16.23 h in the placebo group (p=0.000). No significant difference was observed in vital signs between the regimens. No side effects and no new complaints attributable to the dexamethasone and azithromycin were observed. Sore throat and odynophagia in patients with acute exudative pharyngitis may respond better to treatment with an 8-mg single dose of intramuscular dexamethasone accompanied by an antibiotic regimen than to antibiotics alone.

Determination of advanced life support knowledge level of residents in a Turkish university hospital.

The aim of the study was to determine the advanced cardiac life support (ACLS) knowledge level of residents and related factors in the departments of Anesthesiology, Emergency Medicine, Internal Medicine, and Cardiology in a university hospital. For this cross-sectional study, a total of 20 multiple-choice questions were prepared concerning several different topics, including: fatal dysrhythmias, oxygenation, ventilation and airway control, asystole, and pulseless electrical activity. Questions were given to residents before their periodic training meetings and collected in 30 min. There were 101 of 120 residents from four clinical departments (participation rate 84%) tested. Average point total and standard deviations of all residents were 66.3 +/- 17 out of 100 points. On a departmental basis, statistically significant differences were found in the knowledge level of residents (Emergency Medicine: 86.2 +/- 8.2, Cardiology: 66.7 +/- 12.9, Anesthesiology: 59.3 +/- 16.2, Internal Medicine: 56.1 +/- 13.5, F: 28.6, p < 0.0001). The factors that affect ACLS knowledge level of residents were "postgraduate ACLS training," "awareness of guidelines," and "resuscitation frequency." Postgraduate training and the frequency of ACLS practice seem to increase the ACLS knowledge level of residents. The present study emphasizes the necessity for a standardized systematic postgraduate ACLS training program for the residents of related medical disciplines. Further studies with larger groups are needed to investigate theoretical knowledge, resuscitation skill competency, and related factors.

Angiographic extent of coronary artery stenosis in patients with high and intermediate likelihood of unstable angina according to likelihood classification of American Heart Association.

OBJECTIVE: In accordance with the AHA/ACC clinical practice guideline, the likelihood of acute ischemia caused by coronary artery disease (CAD) is to be determined as high, intermediate, or low for all patients presenting with chest discomfort. This study was conducted to estimate extent of significant CAD in patients with high and intermediate likelihood of unstable angina (UA) according to "AHA likelihood classification". METHODS: Overall, 133 consecutive patients presented with symptoms or signs suggestive of UA, which was classified as of high or intermediate likelihood in Emergency Department (ED), and undergoing coronary angiography (CAG) within one week were enrolled into the study. The characteristics of the patients in either subgroup were compared in terms of the findings of the CAG. RESULTS: In patients with high likelihood of UA (n=89), CAG revealed that 62 had significant CAD, 7-moderate CAD, 20-mild CAD or normal coronary angiogram. In patients with intermediate likelihood of UA (n=19), CAG revealed that 2 patients had significant CAD, and 17-mild CAD or normal coronary angiogram. The rate of significant CAD was significantly higher in patients with high likelihood (p<0.001, LR 23.97, 95% CI 4.21-90.43). The sensitivity and specificity of having at least one of high likelihood features for detecting significant CAD were found to be 96.8% and 38.6% respectively. CONCLUSION: We suggest that the likelihood classification is useful for the triage of the UA patients in the ED. When supported with further studies, utilization of this classification will yield a high diagnostic accuracy in predicting or ruling out severe CAD in patients presenting with chest pain.

Effective treatment of hereditary angioedema with fresh frozen plasma in an emergency department.

Hereditary angioedema (HAE) is a rarely seen disorder of C1 inhibitor (C1-INH) deficiency usually manifested by non-pruritic swelling of the skin. Acute exacerbations are not sensitive to conventional medications, and C1-esterase inhibitor concentrates are recommended as the first-line therapy. However, fresh frozen plasma is the main treatment alternative in many centers due to the lack of C1-esterase inhibitor concentrates. In this report, we present 3 patients with acute exacerbations of hereditary angioedema who were effectively and safely treated with fresh frozen plasma.

Can elevated troponin I levels predict complicated clinical course and inhospital mortality in patients with acute pulmonary embolism?

OBJECTIVE: The purpose of this study was to evaluate the value of elevated cardiac troponin I (cTnI) for prediction of complicated clinical course and in-hospital mortality in patients with confirmed acute pulmonary embolism (PE). METHODS AND RESULTS: This study was a retrospective chart review of patients diagnosed as having PE, in whom cTnI testing was obtained at emergency department (ED) presentation between January 2002 and April 2006. Clinical characteristics; echocardiographic right ventricular dysfunction; inhospital mortality; and adverse clinical events including need for inotropic support, mechanical ventilation, and thrombolysis were compared in patients with elevated cTnI levels vs patients with normal cTnI levels. One hundred sixteen patients with PE were identified, and 77 of them (66%) were included in the study. Thirty-three patients (42%) had elevated cTnI levels. Elevated cTnI levels were associated with inhospital mortality (P = .02), complicated clinical course (P < .001), and right ventricular dysfunction (P < .001). In patients with elevated cTnI levels, inhospital mortality (odds ratio [OR], 3.31; 95% confidence interval [CI], 1.82-9.29), hypotension (OR, 7.37; 95% CI, 2.31-23.28), thrombolysis (OR, 5.71; 95% CI, 1.63-19.92), need for mechanical ventilation (OR, 5.00; 95% CI, 1.42-17.57), and need for inotropic support (OR, 3.02; 95% CI, 1.03-8.85) were more prevalent. The patients with elevated cTnI levels had more serious vital parameters (systolic blood pressure, pulse, and oxygen saturation) at ED presentation. CONCLUSION: Our results indicate that elevated cTnI levels are associated with higher risk for inhospital mortality and complicated clinical course. Troponin I may play an important role for the risk assessment of patients with PE. The idea that an elevation in cTnI levels is a valuable parameter for the risk stratification of patients with PE needs to be examined in larger prospective studies.

Do we really need plain and soft-tissue radiographies to detect radiolucent foreign bodies in the ED?

OBJECTIVE: The objective of this study was to compare 3 imaging techniques-plain radiography, soft-tissue radiography, and ultrasonography-in detecting nonradiopaque foreign bodies in soft tissue. METHODS: In this randomized, blinded, and descriptive in vitro study, 40 chicken thighs with 2 types of nonradiopaque foreign bodies (wood and rubber) and 40 chicken thighs as part of a control group were evaluated to detect soft-tissue foreign bodies with plain radiography, soft-tissue radiography, and high-frequency ultrasonography. RESULTS: The overall sensitivity, specificity, as well as positive predictive and negative predictive values of plain radiography for both nonradiopaque foreign bodies were 5%, 90%, 33%, and 48%, respectively; those of soft-tissue radiography for both nonradiopaque foreign bodies were 5%, 90%, 33%, and 48%, respectively; and those of ultrasonography for both nonradiopaque foreign bodies were 90%, 80%, 81%, and 89%, respectively. CONCLUSIONS: In this experimental model, the results show that high-frequency ultrasonography is superior to plain and soft-tissue radiographies and that the latter 2 techniques are similarly poor at detecting nonradiopaque foreign bodies.

The diagnostic value of QT dispersion for acute coronary syndrome in patients presenting with chest pain and nondiagnostic initial electrocardiograms.

BACKGROUND: Patients presenting with chest pain and nondiagnostic electrocardiograms (ECG) in the emergency department (ED) often pose a challenge to physicians. QT dispersion (QTD) is an electrocardiographic marker of myocardial ischemia due to nonhomogenous ventricular repolarization. We hypothesized that QTD could accurately identify patients with acute coronary syndrome (ACS) who presented with chest pain and nondiagnostic initial ECGs. METHODS: All patients admitted to the ED with chest pain and nondiagnostic initial ECGs were included in the study prospectively. QTD and QTc dispersion (QTcD) were measured at the initial ECGs and compared for ACS patients vs. non-ACS patients. A receiver operating characteristic curve was drawn to evaluate the diagnostic value of QTD and QTcD for ACS. RESULTS: Of the 137 patients with an initially nondiagnostic ECG, 51 were finally diagnosed with ACS (37%). Mean QTD and QTcD of patients with ACS were significantly greater than those of patients without ACS (39.61 +/- 12.9 vs. 32.56 +/- 15.1, p=0.004; 46.12 +/- 16.3 vs. 38.10 +/- 18.2, p=0.009, respectively). The area under the curve was 0.624, p=0.015 for QTD, and 0.603 and p=0.049 for QTcD. When various cut-off points were evaluated, potentially useful values were determined between 30 and 50 ms for QTD (sensitivity 86% and 10%, specificity 35% and 97%, respectively). These values were 40.5 and 49.5 ms for QTcD (sensitivity was 96% and 32%, specificity was 12% and 77%, respectively). CONCLUSION: For patients with chest pain and nondiagnostic initial ECG, ACS risk is high if QTD and QTcD values are greater than 40 ms. Therefore, QTD and QTcD can help identify patients with acute coronary syndrome who present with chest pain and a nondiagnostic initial ECG. However, poor operator characteristics of QT dispersion could limit its value as a diagnostic test in the clinical setting.

Acute myocardial infarction associated with amitriptyline overdose.

Tricyclic antidepressant overdose is known to cause cardiopulmonary and central nervous system complications. As with other cardiovascular complications, amitriptyline toxicity may cause acute myocardial infarction. This paper reports the case of a young female with acute myocardial infarction as a novel consequence of tricyclic antidepressant overdose.

Acute myocardial infarction after hydrochloric acid ingestion.

We report a case of acute ST segment elevated myocardial infarction associated with hydrochloric acid ingestion. Severe systemic acidosis developed shortly after massive hydrochloric ingestion; it was complicated by the presence of acute myocardial infarction. A new complication of acid ingestion is presented and a possible mechanism is discussed.
