The Relationship Between Depression, Anxiety, and Stress Levels and Eating Behavior in Emergency Service Workers.

Introduction It is seen that shift work causes various biological, psychological, and behavioral problems in individuals. This study aimed to determine the eating attitudes and behaviors of health workers working in shifts in a stressful environment such as the emergency service and to examine the relationship between depression, anxiety, and stress levels and eating behaviors (emotional eating, restrictive eating, and external eating) in terms of sociodemographic and clinical characteristics. Material and Methods Sociodemographic data form; Depression, Anxiety, and Stress Scale (DASS); and Dutch Eating Behavior Questionnaire (DEBQ) were used. The study sample consisted of 92 employees (doctor, nurse, emergency medical technician (EMT), medical secretary, and security, staff) who were actively on duty in the emergency department of Alanya Alaaddin Keykubat University Medical Faculty Training and Research Hospital. Results In our study, when the eating behavior of emergency service workers was evaluated in terms of "emotional, external, and restricted eating" sub-dimensions, depression (p=0.043), anxiety (p=0.017), increased stress levels (p=0.002), being female (p=0.022), nurse-emergency medical technician profession (p=0.001), working in 24-hour shifts (p=0.001), and diet history (p=0.013) were associated with "emotional eating." In addition, an increase in depression levels (p=0.048), being single (p=0.015), working in 24-hour shifts (p=0.005), a decrease in age (p<0.001) with "extrinsic eating," an increase in body mass index (BMI) (p=0.020) and waist circumference (p=0.049), and diet history (p<0.001) were associated with "restricted eating." Conclusions In our study, among the sociodemographic factors, being female, being single, working in 24-hour shifts, diet history, nurse-EMT profession, and undergraduate education level were found to increase the tendency to develop eating behavior problems. An increase in depression levels, being single, working in 24-hour shifts, and a decrease in age were associated with "extrinsic eating." There is a correlation between depression, anxiety, and stress scores and emotional eating scores. Additionally, we found significant correlations between body mass index, waist circumference, diet history, and restricted eating scores. In the approach to eating behavior problems, it is important to determine the individual eating behavior disorder. Due to the increased risk of eating behavior disorder in those who work in long shifts such as 24 hours, it will be possible to organize work programs and increase the quality of service.

Accuracy of emergency physicians' interpretation of computed tomography for urgent-emergent diagnoses in nontraumatic cases.

OBJECTIVE: The aim of this study is to evaluate the accuracy levels of the emergency physicians (EPs) managing the patient in the interpretation of the urgent-emergent pathological findings in thoracic and abdominal computed tomography (CT) scans. METHODS: The EPs interpreted the CT scans of patients who visited the emergency department because of nontraumatic causes. Then, a radiology instructor made final assessments of these CT scans. Based on the interpretation of the radiology instructor, the false-positive rate, false-negative rate, sensitivity, specificity, positive predictive value, negative predictive value, and kappa coefficient (κ) of the EPs' interpretations of the CT scans were calculated. RESULTS: A total of 268 thoracics and 185 abdominal CT scans were assessed in our study. The overall sensitivity and specificity of the EPs' interpretation of the thoracic CT scans were 90% and 89%, respectively, whereas the abdominal CT interpretation was 88% and 86%, respectively. There was excellent concordance between the EPs and the radiology instructor with regard to the diagnoses of pneumothorax, pulmonary embolism, pleural effusion, parenchymal pathology, and masses (κ: 0.90, κ: 0.87, κ: 0.71, κ: 0.79, and κ: 0.91, respectively) and to the diagnoses of intraabdominal free fluid, intraabdominal free gas, aortic pathology, splenic pathology, gallbladder pathology, mesenteric artery embolism, appendicitis, gynecological pathology, and renal pathology (κ: 1, κ: 0.92, κ: 0.96, κ: 0.88, κ: 0.80, κ: 0.79, κ: 0.89, κ: 0.88, and κ: 0.82, respectively). CONCLUSION: The EPs are successful in the interpretation of the urgent-emergent pathological findings in thoracic and abdominal CT scans.

Comparison of diagnostic accuracy of point-of-care ultrasonography and X-ray of bony injuries of the knee.

PURPOSE: We aimed to compare the accuracy of point-of-care ultrasonography (POCUS) and X-ray (XR) in the diagnosis of knee bone fractures and fracture characteristics in cases of injuries to the knee. METHODS: The study was conducted in the emergency department (ED) of a tertiary hospital between March 2017 and March 2019. It included patients who presented to the ED with isolated knee injuries, were suspected to have a bony lesion based on clinical examinations, and were ultimately referred for XR. Five emergency physicians (EPs) who had at least three years of ED experience participated in the study. Before the study, these EPs received training on knee examination and radiographic investigation of the knee joint. They were also trained on how to assess the knee joint using POCUS. The knee bones, patella, femur, tibia, and fibula were evaluated. A POCUS examination of the knee bones was carried out according to the eight-step Kozaci Protocol. RESULTS: This study included 92 patients with knee trauma. The mean age of the patients was 34 ± 16 years (6-55 years). Using POCUS and XR, fractures were detected in 40 (43%) and 32 patients (35%), respectively. Relative to XR, for detecting fractures, POCUS showed sensitivity, specificity, positive predictive value, and negative predictive value of 97%, 85%, 78%, 98%, respectively, and the kappa value was 0.774. POCUS examination revealed hematoma and edema in the soft tissue in 34 (37%) patients and hemarthrosis in 33 patients (36%). CONCLUSION: XR is the first and most widely used imaging modality to identify fractures of the knee bone trauma. However, POCUS examination can successfully diagnose bony lesions of the knee in patients with stable vital signs and without life-threatening injuries. It can also easily diagnose hematoma and hemarthrosis. Therefore, POCUS can be used as a diagnostic tool in emergency situations where XR is not available.

Mortality Predictors in Patients Diagnosed with COVID-19 in the Emergency Department: ECG, Laboratory and CT.

Background and Objectives: The aim of this study was to investigate parameters that can be used to predict mortality in patients diagnosed with COVID-19 in the emergency department (ED). Materials and Methods: Patients diagnosed with COVID-19 in the ED were included in this prospective study. The patients were divided into two groups. The surviving patients were included in Group 1 (survivors), and the patients who died were included in Group 2 (non-survivors). The electrocardiogram (ECG), laboratory results and chest computerized tomography (CCT) findings of the two groups were compared. The CCT images were classified according to the findings as normal, mild, moderate and severe. Results: Of the 419 patients included in the study, 347 (83%) survived (survivor) and 72 (17%) died (non-survivor). The heart rate and respiratory rate were found to be higher, and the peripheral oxygen saturation (SpO2) and diastolic blood pressure (DBP) were found to be lower in the non-survivor patients. QRS and corrected QT interval (QTc) were measured as longer in the non-survivor patients. In the CCT images, 79.2% of the non-survivor patients had severe findings, while 11.5% of the survivor patients had severe findings. WBC, neutrophil, NLR, lactate, D-dimer, fibrinogen, C- Reactive Protein (CRP), urea, creatinine, creatine kinase-MB (CK-MB) and hs-Troponin I levels were found to be higher and partial pressure of carbon dioxide (PCO2), base excess (BE), bicarbonate (HCO3), lymphocyte eosinophil levels were found to be lower in non-survivor patients. The highest AUC was calculated at the SpO2 level and the eosinophil level. Conclusions: COVID-19 is a fatal disease whose mortality risk can be estimated when the clinical, laboratory and imaging studies of the patients are evaluated together in the ED. SpO2 that is measured before starting oxygen therapy, the eosinophil levels and the CT findings are all important predictors of mortality risk.

Relationship between internal carotid artery stenosis grade and optic nerve sheath diameter measured by transorbital ultrasonography.

PURPOSE: To assess the consequence of the presence, grade, and asymmetry of carotid artery stenoses on the optic nerve sheath diameter (ONSD) measured by ultrasonography. METHODS: ONSD was measured with B-mode ultrasonography in 129 patients referred for duplex and color Doppler imaging of the carotid arteries. Internal carotid artery stenosis was graded on the basis of peak systolic flow velocity. RESULTS: The mean ONSD was 3.04 ± 0.38 mm in the patients without or with <50% internal carotid artery stenosis and 2.46 ± 0.35 mm in those with >70% stenosis. There was an average difference of 0.58 mm between the ONSD of the patients with <50% and the patients with >70% stenosis. CONCLUSION: ONSD is lower in patients with carotid artery stenosis. Carotid arteries should be investigated, especially in patients with cardiovascular risk factors or diseases, before interpreting ONSD values.

Comparison of the diagnostic accuracy of X-ray and computed tomography in patients with wrist injury.

BACKGROUND: This study aimed to compare CT and XR images of patients admitted to the emergency department due to wrist injuries and to evaluate the accuracy of XR in the diagnosis of fractures. METHODS: Patients; who admitted to ED with injuries due to wrist trauma and who underwent XR imaging and CT scans in the period from 1 January 2017 to 1 January 2018, were included in the study. CT scan image interpretation reports recorded in the hospital automation system were considered eligible to be included in the study. XR images were interpreted by an orthopedics and traumatology specialist. The sensitivity (Sn), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV) and Kappa (κ) coefficient of XR were calculated according to CT. Inter-rater agreement was graded according to κ values. RESULTS: A total of 274 patients were included in the study. Fractures were identified in the XR images in 180 (66%) patients and in the CT images in 196 (72%) patients. Compared to CT, the Sn, Sp, PPV, NPV and κ coefficient of XR were 89%, 92%, 97%, 77% and 0.764 respectively. Compared to CT, the highest sensitivity of XR was measured to detecting radius (Sn: 95%, κ: 0.896) and 5th metacarpal fractures (Sn: 77%, κ: 0.859), the lowest sensitivity of XR was calculated in detecting scaphoid, capitate, pisiform, trapezium hamate, and triquetrum fractures (Sn: 59-14%, κ: 0.619-0.240). The sensitivity and κ coefficient of XR were calculated 54% and 0.530 in the adjacent bone fracture, 83% and 0.830 in joint dislocation, 75% and 0.661 in the fractures extending to the joint space. CONCLUSIONS: XR is the first-choice imaging modality in the evaluation of wrist injuries, but CT imaging should be preferred when fractures extending to the joint space, adjacent bone fracture and carpal bone fracture are being considered.

Ingested Foreign Body Imaging Using Point-of-Care Ultrasonography: A Case Series.

The ingestion of foreign bodies is a common problem in the pediatric population. Emergent treatment of ingested foreign bodies is dependent on the type of foreign body ingested, patient symptoms, timing of ingestion, and the location of the foreign body. Although X-ray and computed tomography are the imaging techniques used most often to assess for foreign bodies, ultrasonography, which lacks ionizing radiation, may also be useful. This case series describes 8 cases of gastrointestinal tract foreign bodies and the utility of point-of-care ultrasonography for their real-time evaluation.

Comparison of X-Ray Imaging and Computed Tomography Scan in the Evaluation of Knee Trauma.

Background and objectives: The aim of the study was to compare the accuracy of X-ray (XR) imaging according to computed tomography (CT) scanning in the diagnosis of knee bone fractures, and in the determination of fracture characteristics, and to identify CT scan indications in patients with knee trauma. Materials and methods: The patients who presented to the emergency department (ED) due to knee trauma between January 2017 and December 2018 and who underwent XR imaging and CT scans were included in the study. XR images were reinterpreted by an emergency physician. The official reports, which had been interpreted by a radiologist in the hospital automation system for CT images, were considered valid. Results: Five hundred and forty-eight patients were included in the study. Of the patients, 200 (36.5%) had fractures in XR imaging and 208 (38.0%) had fractures in CT scans. Compared to CT scanning, XR imaging was found to have 89% sensitivity, 95% specificity, 92% positive predictive value, and 92% negative predictive value in identifying the fracture. The sensitivity of XR imaging in identifying growth plate fracture, angulation, stepping off, and extension of the fracture into the joint space was determined as 78% and less. According to the kappa value, there was determined a perfect concordance between the XR imaging and CT scans in angulation, stepping off, and extension of the fracture into the joint space. This concordance was moderate in growth plate fractures. Conclusions: XR imaging has a low sensitivity in identifying knee fractures. There is a moderate concordance between XR imaging and CT scanning in identifying growth plate fractures. Therefore, CT scanning should be performed in patients whose fracture type and fracture characteristics are not able to be determined exactly with XR imaging in knee injury.

The Visualization of a Foreign Body in a Patient's Subglottic Region Using Point-of-Care Ultrasonography.

Point-of-care ultrasonography is a real-time dynamic examination that is useful for evaluating the location of foreign bodies in a patient's gastrointestinal tract and soft tissue. In particular, it is useful for identifying radiolucent foreign bodies that are difficult to visualize using routine x-ray examinations. This case study describes the visualization of a radiolucent foreign body in a patient's subglottic region using point-of-care ultrasonography.

The Measurement of Elderly Volunteers' Optic Nerve Sheath Diameters by Ocular Ultrasonography.

BACKGROUND AND OBJECTIVES: The optic nerve is a component of the central nervous system, and the optic nerve sheath is connected to the subarachnoid space. For this reason, intracranial pressure (ICP) increases are directly transmitted to the optic nerve sheath. Knowing the normal optic nerve sheath diameter (ONSD) range in a healthy population is necessary to interpret this measurement as a sign of intracranial pressure in clinical practice and research. In this study, we aimed to determine the standard ONSD value in healthy adultsaged65 years of age or older who had not previously been diagnosed with a disease that could increase the ICP. MATERIALS AND METHODS: The right and left ONSD values and ONSD differences were compared, according to the gender of the patients. The patients were divided into 3 groups, according to their age. The age groups were assigned as follows: Group 1: 65-74 years of age; Group 2: 75-84 years of age; and Group 3: 85 years of age or older. The ONSDs and the ONSD difference between the left and right eyes of Group 1, Group 2 and Group 3 were compared. RESULTS: The study included 195 volunteers. The mean ONSD of both eyes was 4.16±0.69 mm, and the difference between the ONSD of the left and right eyes was 0.16±0.18 mm. There was no difference between genders in terms of right ONSD, left ONSD, mean ONSD and ONSD difference between the left and right eyes. There was no correlation between age and ONSD and ONSD difference. When the age groups and ONSD were compared, no difference was found between the groups. CONCLUSIONS: In conclusion, the ONSDs of both eyes do not vary with age in healthy adults aged65 years or older. ONSD does not vary between genders. The calculation of ONSD difference can be used to determine ICP increase.

Comparison of Point-of-Care Ultrasonography and Radiography in the Diagnosis of Long-Bone Fractures.

Background and objectives: In this study, the accuracy of point-of-care ultrasonography (POCUS) was compared to radiography (XR) in the diagnosis of fractures, the determination of characteristics of the fractures, and treatment selection of fractures in patients admitted to the emergency department (ED) due to trauma and suspected long bone (LB) fractures. Materials and Methods: The patients were included in the study, who were admitted to ED due to trauma, and had physical examination findings suggesting the presence of fractures in LB (humerus, radius, ulna, femur, tibia, and fibula). The patients were evaluated by two emergency physicians (EP) in ED. The first EP examined LBs with POCUS and the second EP examined them with XR. LBs were evaluated on the anterior, posterior, medial, and lateral surfaces and from the proximal joint to the distal one (shoulder, elbow, wrist, hip, knee, and ankle joint) in both longitudinal and transverse axes with POCUS. Results: A total of 205 patients with suspected LB fractures were included in the study. LB fractures were determined in 99 patients with XR and in 105 patients with POCUS. The sensitivity, specificity, positive predictive value, negative predictive value of POCUS in determining the fractures were 99%, 93%, 93%, and 99%, respectively, compared to XR. Compared to XR, POCUS was able to determine 100% of fissure type fractures (kappa (κ) value: 0.765), 83% of linear fractures (κ: 0.848), 92% of fragmented fractures(κ: 0.756), 67% of spiral fractures (κ:0.798), 75% of avulsion type fractures (κ: 0.855), and 100% of full separation type fractures (κ: 0.855). Conclusions: This study has demonstrated that POCUS has a high sensitivity in diagnosing LB fractures. POCUS has a high sensitivity in identifying fracture characteristics. POCUS can be used as an alternative imaging method to XR in the diagnosis of LB fractures and in the determination of fracture characteristics.

Comparison of ultrasonography and computed tomography in the determination of traumatic thoracic injuries.

OBJECTIVE: In this study, the accuracy of bedside thoracic ultrasonography (TUSG) performed by emergency physicians with patients in the supine position was compared with that of thoracic computed tomography (TCT) for the determination of thoracic injuries due to trauma. METHODS: Patients who suffered the multiple traumas, whose thoracic trauma was identified on physical examination or TCT imaging were included in the study. TUSG was performed following a physical examination by the emergency physician who managed the trauma patient. Subcutaneous emphysema, pneumothorax, pulmonary contusions (PCs), hemothorax, pericardial effusion and tamponade, sternal and clavicular fractures and rib fractures were identified by TUSG. TCT imaging was performed after the ultrasonography examination was completed. RESULTS: Eighty-one patients were included in the study. TCT scans showed subcutaneous emphysema in 16 (19.8%) patients, pneumothorax in 21 (25.9%), PCs in 27 (33.3%), hemothorax in 20 (24.7%), sternum and clavicular fractures in 6 (7.4%) and rib fractures in 21 (25.9%). The sensitivity and specificity of ultrasonography varied for detecting the following pathologies: subcutaneous emphysema (56% and 95%), pneumothorax (86% and 97%), hemothorax (45% and 98%), PCs (63% and 91%), sternal fractures (83% and 97%), clavicular fractures (83% and 100%) and rib fractures (67% and 98%), respectively. CONCLUSION: In conclusion, ultrasound was found to be highly specific but only moderately sensitive for the identification of thoracic injuries.

The comparison of point-of-care ultrasonography and radiography in the diagnosis of tibia and fibula fractures.

OBJECTIVE: We aimed to compare the efficacy of Point-of-care ultrasonography (POCUS) with radiography in the diagnosis of tibia fracture (TF) and fibula fracture (FF), and determation of fracture characteristics. METHODS: Patients aged 5-55 years who were admitted to ED due to low-energy, simple extremity trauma, who had a suspected TF and FF on physical examination were included in this prospective study. One physician performed POCUS examination. Other physician evaluated the radiography images. The obtained results were compared. RESULTS: A total of 62 patients were included in the study. TF was detected in 21 patients by radiography and in 24 patients by POCUS. FF was detected in 24 patients by radiography and in 25 patients by POCUS. Ten of the patients had both TF and FF. Compared with radiography, sensitivity, specificity, PPV and NPV of POCUS in the detection of TF were 100%, 93%, 88% and 100% (95% CI, 91-100%), respectively. Compared with direct X-ray imaging, sensitivity, specificity, PPV and NPV of POCUS in the detection of FF were 100%, 97%, 96% and 100% (95% CI, 96-100%), respectively. We determined that POCUS is also successful in detection of fracture features such as angulation, step-off, extension into the joint space that can determine the treatment decision. CONCLUSION: This study demonstrated that POCUS was found to be as successful as direct X-ray imaging in the diagnosis of TF and FF.

Effect of Focused Bedside Ultrasonography in Hypotensive Patients on the Clinical Decision of Emergency Physicians.

We assessed the effect of focused point of care ultrasound (POCUS) used for critical nontraumatic hypotensive patients presenting to the emergency department of our hospital on the clinical decisions of the physicians and whether it led to the modification of the treatment modality. This prospective clinical study was conducted at the Emergency Department of Antalya Training and Research Hospital. Nontraumatic patients aged 18 and older who presented to our emergency department and whose systolic blood pressure was <100 mmHg or shock index (heart rate/systolic blood pressure) was >1 were included in the study. While the most probable preliminary diagnosis established by the physician before POCUS was consistent with the definitive diagnosis in 60.6% (n = 109) of 180 patients included in the study, it was consistent with the definitive diagnosis in 85.0% (n = 153) of the patients after POCUS (p < 0.001). POCUS performed for critical hypotensive patients presenting to the emergency department is an appropriate diagnostic tool that can be used to enable the physicians to make the accurate preliminary diagnosis and start the appropriate treatment in a short time.

The comparison of radiography and point-of-care ultrasonography in the diagnosis and management of metatarsal fractures.

OBJECTIVE: It was aimed to compare the efficacy of point-of-care ultrasonography (POCUS) with radiography in the diagnosis and management of metatarsal fracture (MTF). METHODS: Patients aged 5-55 years admitted to emergency room due to low-energy, simple extremity trauma and had a suspected MTF, were included in this prospective study. Patients were evaluated by two different emergency physicians in the emergency room. The first physician performed POCUS examination. Second physician evaluated the radiography images. The obtained results were compared. RESULTS: Seventy-two patients were enrolled in the study. Fracture was detected in 39% by radiography and in 43% of patients by POCUS. Multiple MTFs were identified in 5% of patients. Compared with radiography, POCUS had a sensitivity of 93%, specificity of 89%, positive predictive value of 84% and a negative predictive value of 95% (95% CI, 83-98%) in the detection of fractures. While soft tissue edema was seen in 61% of patients by POCUS, soft tissue edema with hematoma was detected in 14%. Compared with radiography, the sensitivity and specificity of POCUS in the decision for surgery were 100% and 98% (95% CI, 97-100%), respectively, whereas its sensitivity and specificity were both 100% in the decision for reduction. CONCLUSION: In our study, we demonstrated that POCUS could be applied with success in the diagnosis and treatment of MTF in low-energy injuries. POCUS can be used as an alternative to radiography in the emergency rooms due to being easy to learn and practice and availability of soft tissue examination along with bone tissue examination.

Detection of the awareness rate of abuse in pediatric patients admitted to emergency medicine department with injury.

OBJECTIVE: It was aimed to investigate whether neglected and abused pediatric patients are properly recognized and reported by emergency physicians in the emergency department (ED). METHODS: This prospective study was conducted on patients between 0 and 6 years of age presenting with trauma to ED. Patients were examined again by an emergency medicine specialist independent from the physician who did the first intervention during clinical follow-up phase after notification of patients presenting with trauma to emergency physician. Asked radiological examinations and clinical follow-up were performed. The suspected abuse evaluation form, consisting 12 items, which was formed by considering the forms used in previous studies was used to examine the awareness of physicians in cases of abuse suspicion. RESULTS: A total of 126 patients were included in our study. 54% of cases (n = 68) were male and mean age was determined to be 31.3 ± 18.9 months. It was found that no judicial records were written to 35.7% (n = 45) of our patients and that 11.1% (n = 5) of these patients were hospitalized. In 51.1% (n = 23) of patients without judicial records, multiple suspected abuse findings were identified. According to evaluation of first physician, it was found that 75.9% (n = 41) of discharged patients had no judicial records and was not considered as neglect and abuse. CONCLUSION: We conclude that detection rates of abuse can be increased by developing child abuse screening forms and ensuring the continuity of the necessary training programs.

Thrombolytic therapy delay is independent predictor of mortality in acute pulmonary embolism at emergency service.

Acute pulmonary embolism (PE) carries a high risk of morbidity and mortality. Delays in diagnosis or therapy may result in sudden, fatal deterioration; therefore, rapid diagnosis and an appropriate therapeutic approach are needed. We aimed to investigate the effect of delaying thrombolytic administration on the mortality rate in a suspected PE. We retrospectively analyzed 49 consecutive patients who were aged 18 years or older and received thrombolysis for a high-risk PE without a major contraindication. All patients were classified according to the time of onset of the thrombolytic therapy. Patients experiencing cardiopulmonary arrest were analyzed from the time of admission to thrombolytic administration with 10-minute cutoff values. Data were analyzed by a regression analysis and a receiver operating characteristic (ROC) analysis for significant and independent associated risk factors and in-hospital mortality. Mortality was seen in 17 of the 49 cases. Thirteen of these had received thrombolytic therapy 1 hour after their emergency department (ED) admission. Among all cases, the mortality rate was 35%. The ROC analysis indicated that a > 97-second delayed thrombolytic administration time was associated with mortality with 53% sensitivity and 91% specificity (area under the curve, 0.803; 95% confidence interval, 0.668-0.938). In the logistic regression, a 5-minute delay in thrombolytic therapy (beta = 1.342; 95% confidence interval, 1.818-2.231; p = 0.001) was associated with in-hospital mortality in the multivariable model. No major bleeding complications were seen in PE survivors. We conclude that early onset thrombolytic therapy in the ED for high-risk and hemodynamically worsening patients appears safe and life-saving.

CT interpretations in multiply injured patients: comparison of emergency physicians and on-call radiologists.

OBJECTIVE: In this study, emergency physicians and on-call radiologists were compared regarding identification of fatal injuries on computed tomographic (CT) scans in patients with trauma. MATERIALS AND METHODS: Multiply injured patients who were older than 18 years and underwent CT scanning were included in the study. The CT scans were interpreted by the responsible emergency physician. At the same time, these images were also evaluated by the on-call radiologist. Final evaluation was done 1 week later by a radiology instructor who knew the clinical follow-up of the patient. RESULTS: The study included 156 patients. The mean age of the patients included in the study was found to be 41.6 years. Less than half (33.5%) of the patients were female and 86.5% were male. A total of 482 CT scans were performed in the patients. Regarding brain CTs, the concordance rate for emergency physicians was 98%, whereas it was 94% for on-call radiologists. Regarding thoracic CTs, the concordance rate for emergency physicians was 91%, whereas was 93% for on-call radiologists. There was a perfect concordance (κ value > 0.75) for on-call radiologists and emergency physicians in terms of brain and thoracic CTs. Regarding abdominal-pelvic CTs, the concordance rate for emergency physicians was 97%, whereas it was 98% for on-call radiologists. Moderate concordance (κ range = 0.40-0.75) was detected for emergency physicians in terms of identification of liver, spleen, kidney, and intra-abdominal/retroperitoneal hemorrhages. There was a perfect concordance (κ value > 0.75) for pelvic fractures. CONCLUSION: In this study, it was shown that emergency physicians were successful in identifying fatal injuries on trauma CT images after a short-term training on interpretation of trauma CTs.

The comparison of bedside point-of-care ultrasound and computed tomography in elbow injuries.

OBJECTIVE: The objective of the study was to compare the efficacy of point-of-care ultrasound (POCUS) and computed tomography (CT) in the diagnosis of the fracture of the bones that form the elbow joint and the determination of treatment method in elbow injuries. METHODS: Forty-nine patients aged 5 to 65 years, who were admitted with low-energy elbow injuries, had at least 1 fracture of the elbow joint bones, and underwent CT scanning, were included in this study. Before the initiation of the study, orthopedic surgeons and emergency physicians determined a common treatment based on the fracture characteristics. Patients were first evaluated with direct radiography, and then with POCUS by trained emergency physicians. Emergency physicians made treatment decisions based on the ultrasonography results. Then, CT scans were performed. The CT images were interpreted by radiologists. Orthopedic surgeons made treatment decisions based on the CT interpretations. RESULTS: Forty-nine patients with elbow injury were included in the study. Eighteen (37%) patients were women, and 31 (63%) were men. The mean age was 21 ± 15 years. Compared with CT, sensitivity, specificity, positive predictive value, and negative predictive value of POCUS in fracture detection were 97%, 88%, 94%, and 93%, respectively. Although the sensitivity and specificity of POCUS in the decision for reduction were 95% and 100%, respectively, it was 93% and 100% in the decision for surgery. CONCLUSION: In conclusion, POCUS was shown to be successfully applied in the diagnosis and management of elbow injuries, in which direct radiography was inefficient and CT scans were required.

Investigation of oxidant and antioxidant levels in patients with acute stroke in the emergency service.

OBJECTIVE: In this study, we aimed to identify oxidative stress and the disruption in the oxidant-antioxidant balance in the acute phase of stroke and, therefore, to detect markers that will guide in the diagnosis and treatment of stroke. MATERIALS AND METHODS: Eighty-six patients who were admitted to Antalya Training and Research Hospital Emergency Department between June 2013 and December 2013 and who were diagnosed as having stroke were enrolled in this study. The control group consisted of 40 healthy volunteers. Blood samples collected from all participants were screened for albumin, ischemic modified albumin (IMA), IMA/albumin ratio (IMAR), total antioxidant status, total oxidant status (TOS), and oxidative stress index (OSI). RESULTS: Sixty (70%) patients were diagnosed as having acute cerebral infarction (ACI) and 26 (30%) as having acute intracerebral hemorrhage (AIH). Statistically significant difference was found between AIH and control groups in terms of albumin, IMAR, TOS, OSI levels (P < .001, P < .001, P < .001, and P < .001, respectively). Statistically significant difference was found between ACI and control groups in terms of albumin, IMA, IMAR, TOS, and OSI levels (P < .001, P = .045, P < .001, P < .001, and P < .001, respectively). There was no difference between ACI patients with detected acute infarcts on cranial computed tomographic scans (n = 31) and ACI patients with normal cranial computed tomography results (n = 29) in terms of oxidant-antioxidant levels. There was a significant difference between patients admitted within 3 hours and healthy adults regarding the levels of IMAR, TOS, and OSI (P < .001, P < .001, and P < .001, respectively). DISCUSSION AND CONCLUSION: It was seen that oxidant-antioxidant balance was impaired in favor of oxidants in ACI and AIH. In addition, impairment in oxidant-antioxidant balance was found in the early stages of ACI. Therefore, these biomarkers can be used especially in the early diagnosis of thrombolytic therapy candidates in ACI.
