Salim Satar; Metin Topal; Nalan Kozaci

Caustic products are responsible for the most serious cases of poisoning, which are always emergency cases. In this paper, we review demographic features and endoscopic results of the patients admitted to a university emergency department with a history of caustic substance ingestion between January 2000 and June 2003. Thirty-seven patients were included in this study. Twenty-one of the patients were female and 16 were male. The mean age of the patients was 30.9 ± 14.7 years. The agents included sodium hypochlorite in 24 patients and hydrochloric acid in 13 patients. All the patients ingested these agents orally. The mean interval time of admission to emergency department after ingestion of caustic agent was 5.4 ± 5.6 hours. Endoscopy was attempted in 37 patients. Endoscopic results were as follows: grade 0 in 8 (21.6%) patients, grade 1 in 17 (45.9%) patients, grade 2a in 5 (13.5%) patients, and grade 2b in 7 (18.9%) patients. We believe that early signs and symptoms after caustic substance ingestion are not consistent with the extent of damage, and endoscopy is the only reliable method to assess injury. It is important that efforts should be made to educate the public about the dangers of caustic substances so that their threat may be diminished.

OBJECTIVE The aim of the study was to compare the effectiveness of point-of-care ultrasound (POCUS) with direct radiography in diagnosis and management of the patients with distal radius fractures (DRFs). METHODS In this study, patients between ages 5 and 55 years admitted to the emergency department with low energy upper extremity trauma with suspected DRF were evaluated with POCUS and direct radiography by emergency physicians (EPs) trained in either musculoskeletal (MSK) imaging or x-ray interpretation of DRF. The EP performing the POCUS examination was blinded to the x-ray results. RESULTS A total of 83 patients with DRF were included in the study. There were 18 (22%) females, and 65 (78%) males enrolled in the study. Mean age was 13 ± 14 years for males, and 15 ± 13 years for females. Compared with direct radiography, POCUS yielded 98% sensitivity, 96% specificity, 98% positive predictive value, 96% negative predictive value, and 98% accuracy of the test in detecting fractures. POCUS yielded 96% sensitivity, 93% specificity value in detecting linear fractures; 78% sensitivity, 98% specificity in detecting torus-type fractures, and 100% specificity and sensitivity for detecting fissure fractures. Specificity of POCUS in the decision for reduction was 100% and sensitivity was 98%; specificity was 100% for splint application. CONCLUSION In our study, it was shown that POCUS could be applied easily by EPs trained in MSK POCUS imaging with success in diagnosing DRF and determining the correct fracture type and required treatment methods.

BACKGROUND Ocular ultrasonography of optic nerve sheath diameter (ONSD) to determine intracranial pressure (ICP) has become favorable in recent years. OBJECTIVE To demonstrate the efficacy of ONSD measurement in determining the ICP increase due to nontraumatic events in the emergency department. METHODS A total of 100 patients with suspected nontraumatic intracranial event were enrolled in this prospective study. Patients were divided equally into 2 groups including 50 patients as group I with pathology on cranial computed tomography (CT) and group II with normal cranial CT. Prior to CT scans, patients underwent ONSD measurement by a radiologist using 11- and 14-MHz transducers. RESULTS The ONSD values of groups I and II were 5.4±1.1and 4.1±0.5mm, respectively. Optic nerve sheath diameter was found to be larger on the side of lesion in patients with a lesion (P<.05). The cutoff value of the difference between ONSD values of both eyes in the presence of pathology was determined as 0.45 (sensitivity, 80%; specificity, 60%; the area under the curve, 0.794; 95% confidence interval, 0.705-0.883). The between-ONSD and midline shift size was statistically significant (r=0.366, P=.009). The cutoff value of ONSD for the detection of midline shift was determined as 5.3mm (sensitivity, 70%; specificity, 74%; the area under the curve, 0.728; 95% confidence interval, 0.585-0.871). CONCLUSION Optic nerve sheath diameter measurement via bedside ocular ultrasonography in patients with suspected intracranial event in the emergency department is a useful method to determine ICP increase and its severity.

OBJECTIVE We aimed to compare the effectiveness of point-of-care ultrasonography (POCUS) with direct radiography (DR) in the diagnosis and management of the patients with metacarpal fractures (MFs). METHODS Patients between ages 5 and 55 years admitted to the emergency department with suspected MFs were included to the study. Emergency physicians (EPs) participating in the study were divided into 2 groups (POCUS, DR). Patients were evaluated by one of the EPs from each group. The EP performing the POCUS examination was blinded to the radiograph results. RESULTS A total of 66 patients with MFs were included to the study. Fracture was determined in 36 (55%) patients with DR and in 37 (56%) patients with POCUS. When compared with radiography, the sensitivity of fracture detection with POCUS was 92%; specificity, 87%; positive predictive value, 89%; and negative predictive value, 90% (95% confidence interval, 80%-98%). Sensitivity of detecting localization of the fracture with POCUS was 92%; specificity, 87%; positive predictive value, 89%; and negative predictive value, 89% (95% confidence interval, 80%-98%). Of the patients with fracture, 69% have angulation and 24% have step-off determined with POCUS. Specificity of POCUS in the decision for treatment choice was 100%, and sensitivity was 99%. CONCLUSION We found that POCUS could be applied easily with success by EPs in diagnosing MFs, determining the type of the fracture and required treatment methods correctly. Point-of-care US can be used to rule out a suspected MF, thereby avoiding the time and expense of radiography.

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.

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.

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.

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.

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.

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.
