Publication Open Access Electrocardiographic clue for a mid-LAD lesion(2016-03-17) ONUR, ÖZGE ECMEL; Ak, Rohat; Doganay, Fatih; Onur, Ozge Ozberk; Akoglu, Ebru UnalPublication Open Access Initial inferior vena cava and aorta diameter parameters measured by ultrasonography or computed tomography does not correlate with vital signs, hemorrhage or shock markers in trauma patients(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2017) DENİZBAŞI ALTINOK, ARZU; Celik, Omer Faruk; Akoglu, Haldun; Celik, Ali; Asadov, Ruslan; Onur, Ozge Ecmel; Denizbasi, ArzuBACKGROUND: Ultrasonography (US) is noninvasive, readily available, and cheap. The diameter of inferior vena cava (dIVC) and its respiratory variation were proposed as a good surrogate of the hemodynamic state. However, recent studies have shown conflicting results, and the value of IVC-derived parameters in the estimation of fluid status and hemorrhage remains unclear. METHODS: This was an observational study of trauma patients who presented to emergency department. dIVC and aorta diameter (dAorta) were measured at the initial US and CT in all patients. The correlation of these measurements and all parameters derived from those measurements along with the initial vital signs and laboratory values of hemorrhage (hemoglobin, hematocrit) and shock (lactate, base excess) were assessed. US and CT values were also compared for accuracy using Bland-Altman analysis. RESULTS: The final study population was 140, with a mean age of 38 years and 79.3% were male. dIVC and dAorta did not have any clinically significant correlation with any of the vital signs or laboratory values of hemorrhage or shock when measured by US or CT. A good and significant correlation was observed between dIVC and dAorta measured by US and CT. CONCLUSION: The value of an initial and single measurement of IVC and aorta parameters in the evaluation of trauma patients should be questioned. However, the change in the measured parameters may be of value and should be investigated in further studies.Publication Open Access Grayanotoxin (Mad Honey) - Ongoing Consumption After Poisoning(AVES YAYINCILIK, 2013-09-10) DENİZBAŞI ALTINOK, ARZU; Eroglu, Serkan Emre; Urgan, Oguz; Onur, Ozge Ecmel; Denizbasi, Arzu; Akoglu, HaldunBackground: Some honey types in certain geographical regions may cause toxic effects on people. This type of honey is known as mad honey in Turkey. The toxic ingredient of this honey is called Grayanotoxin I. The consumption of mad honey can cause severe bradycardia, hypotension, dizziness, nausea and vomiting. Aims: Our study is aimed at analysing patients diagnosed with mad honey poisoning and their behaviour towards the consumption of this honey after diagnosis. Study Design: Cross sectional study. Methods: This cross-sectional study was based on complaints and findings of mad honey poisoning. Patient information and findings at the time of admission were compared with those at one month after discharge through telephone interviews. They were asked if either they or their relatives had continued consuming the same honey. Frequency data such as gender, purpose of honey consumption, first complaints and continuance of honey consumption are shown as number (n) and percentage (%). A Chi Square test was conducted to determine the difference between groups. Results: 38 patients were participated in this study; 18 of the patients had to be followed up in a coronary intensive care unit. We were able to reach 34 patients by phone after discharge. It was found that 12 of 16 patients discharged after emergency unit observation or their close relatives were continuing to consume mad honey, whereas 16 (88.9%) of the 18 patients under coronary intensive care had discontinued consuming mad honey. The difference in the continuation of mad honey consumption between patient groups followed-up in the intensive care unit and those discharged after emergency observation was statistically significant. Conclusion: Hazards associated with and serious consequences following the consumption of mad honey must be clearly explained to patients who are found to be consuming mad honey.Publication Open Access The Effects of Intravenous Lipid Emulsion Therapy in the Prevention of Depressive Effects of Propofol on Cardiovascular and Respiratory Systems: An Experimental Animal Study(MDPI, 2018-12-25) ONUR, ÖZGE ECMEL; Doganay, Fatih; Ak, Rohat; Aliskan, Halil; Abut, Serdar; Sumer, Engin; Onur, OzgeBackground and objectives: Although there are several hypotheses about the mechanism of action, intravenous lipid emulsion (ILE) therapy has been shown to be effective in the treatment of toxicities due to local anaesthetics and many lipophilic drugs. In this study, we had hypothesized that ILE therapy might also be effective in preventing mortality and cardiorespiratory depressant effects due to propofol intoxication. Materials and methods: Twenty-eight Sprague-Dawley adult rats were randomly divided into four groups. Saline was administered to the subjects in the control group. The second group was administered propofol (PP group); the third group was administered ILE (ILE group), and the fourth group was administered propofol and ILE therapy together (ILE+PP group). Systolic blood pressure (SBP), diastolic blood pressure (DBP), respiratory rate (RR), heart rate (HR), and mortality were recorded at 10 time-points during a period of 60 min. A repeated measures linear mixed-effect model with unstructured covariance was used to compare the groups. Results: In the PP group; SBP, DBP, RR, and HR levels declined steadily; and all rats in this group died after the 60-min period. In the ILE+PP group, the initially reduced SBP, DBP, RR, and HR scores increased close to the levels observed in the control group. The SBP, DBP, RR, and HR values in the PP group were significantly lower compared to the other groups (p < 0.01). The mortality rate was 100% (with survival duration of 60 min) for the PP group; however, it was 0% for the remaining three groups. Conclusions: Our results suggest that the untoward effects of propofol including hypotension, bradycardia, and respiratory depression might be prevented with ILE therapy.Publication Open Access Spinal Trauma is Never without Sin: A Tetraplegia Patient Presented Without any Symptoms(2014-12) DENİZBAŞI ALTINOK, ARZU; Efeoglu, Melis; Akoglu, Haldun; Akoglu, Tayfun; Eroglu, Serkan Emre; Onur, Ozge Ecmel; Denizbasi, ArzuPublication Open Access Diagnostic value of Tei index for acute myocardial infarction in patients presenting to emergency department with ischemic chest pain and correlation with Hs-troponin(SAGE PUBLICATIONS LTD, 2019-07) ONUR, ÖZGE ECMEL; Ucar, Asli Bahar; Akoglu, Ebru Unal; Ozturk, Tuba Cimilli; Eyinc, Yalman; Ak, Rohat; Demir, Hasan; Ilgezdi, Zeynep Demet; Onur, OzgeBackground: Acute myocardial infarction is one of the most common causes of mortality in developed countries, and high-sensitive troponin test usually becomes positive within 3 h from the onset of symptoms. Myocardial perfusion index (Tei index) is a parameter measured during the echocardiographic examination. Objectives: The aim of this study is to investigate the diagnostic value of the Tei index for early diagnosis of acute myocardial infarction in the emergency department and to evaluate the correlation between the Tei index and Hs-Troponin value. Materials and Methods: A total of 129 cases were evaluated, and patients were divided into two groups according to their final diagnosis as acute myocardial infarction (non-ST segment elevation myocardial infarction) and non-acute myocardial infarction groups. Baseline and third-hour Hs-Troponin levels and Tei index values were determined, and their correlation was analyzed. Results: A total of 84 cases were diagnosed with acute myocardial infarction (non-ST segment elevation myocardial infarction), 84.5% had positive Tei index results at the time of admission while the remaining 45 patients were diagnosed as non-acute myocardial infarction and only 48.9% of them had positive Tei index. The diagnostic value of the Tei index and Hs-troponin were calculated as 79.8% and 60%; 67.9% and 60%, respectively. Also, we found that a 0.02 or more increase in the Tei index value has a 97.6 sensitivity and 97.5 specificity for the diagnosis of non-ST segment elevation myocardial infarction. A weak correlation was found between the Tei index and Hs-Troponin values in the acute myocardial infarction group (r = 0.425) and a negative correlation in non-acute myocardial infarction patients at presentation. Conclusion: It is suggested that the use of Tei index might be used as a supportive measure for the early diagnosis of acute myocardial infarction, and the deterioration of Tei index seems to be more significant than Hs-Troponin especially in ruling out acute myocardial infarction.Publication Open Access Details of motorcycle accidents and their impact on healthcare costs(TURKISH ASSOC TRAUMA EMERGENCY SURGERY, 2013) DENİZBAŞI ALTINOK, ARZU; Eroglu, Serkan Emre; Toprak, Siddika Nihal; Akoglu, Ebru; Onur, Ozge Ecmel; Denizbasi, Arzu; Ozpolat, Cigdem; Akoglu, HaldunBACKGROUND: Of overall traffic accidents in 2011 in Turkey, 7.58% (n=2 1,107) were motorcycle accidents. Motorcycle accidents and their impact on healthcare costs are investigated in our study. METHODS: Motorcycle accidents that occurred with/without a collision between 1 July 2010 and 30 June 2011 were studied prospectively through the inspection of patients visiting the Emergency Service. The healthcare costs relevant to each person injured in a motorcycle accident were investigated via forms. Data were analyzed using frequencies, Kolmogorov-Smirnov, Mann-Whitney U, and chi-square tests on the SPSS v16.0 program. RESULTS: Ninety-one people involved in accidents, with a mean age of 28.47 years, were studied. The average healthcare expenditure for the 91 patients studied between reception and discharge was US$253.02 (median, US$55.90; range, US$11.52 - 7137.19). According to our study, there was no definitive correlation between the healthcare costs and the time of the accident, motorcycle type, nature of the road surface, protective equipment, weather, or daylight. CONCLUSION: According to the current study, the risk of an accident increases with young adults. Concordantly, healthcare costs increase. Thus, it is important that the legal rules with respect to the age and education necessary for receiving a license to operate a motorcycle should be redefined, and if necessary, regulated.Publication Open Access Ecstasy-induced recurrent toxic hepatitis in a young adult(ELSEVIER, 2008-06) DENİZBAŞI ALTINOK, ARZU; Guneysel, Ozlem; Onur, Ozge Ecmel; Akoglu, Haldun; Denlzbasi, ArzuBACKGROUND: The drug 3,4-methylenedioxymethamphetamine (MDMA), otherwise known as ecstasy, is a synthetic amphetamine that produces euphoria, increases sociability and energy, and is often used as a weekend recreational drug by young adults. CASE SUMMARY: A 23-year-old male (height, 184 cm; weight, 68 kg) presented to the emergency department of Marmara University Hospital, Istanbul, Turkey, with jaundice and nausea lasting for 6 days. The patient reported that he had been a chronic user of MDMA for 2 years. He also reported that I week before presenting, he had ingested twice (2 tablets) the usual amount (I tablet) of the drug at the same time. Blood tests were performed and hematologic findings were as follows: aspartate aminotransferase (AST), 1423 U/L (reference range, 10-37 U/L); alanine aminotransferase (ALT), 2748 U/L (10-40 U/L); alkaline phosphatase, 271 U/L (0-270 U/L); gamma-glutamyl transpeptidase, 124 U/L (7-49 U/L); total bilirubin, 13.23 mg/dL (0.2-1 mg/dL); direct bilirubin, 8.75 mg/dL (0-0.3 mg/dL); amylase, 80 U/L (0-220 U/L); prothrombin time, 21.2 sec; activated partial thromboplastin time, 37.3 sec; and international normalized ratio, 1.66. Liver enzymes and bilirubin levels were found to be extremely high (AST = 40x normal, ALT = 70x normal, and bilirubin = 13x normal). Viral, autoimmune, and metabolic causes were excluded. Serologic tests for hepatitis A, B, and C viruses, mononucleosis, cytomegalovirus, and HIV infection were all negative. A diagnosis of ecstasy-induced toxic hepatitis was made. The patient's medical history further revealed that the current incident was actually his second occurrence of jaundice and acute hepatitis associated with the ingestion of higher amounts (twice the usual amount of MDMA he ingested at the same time). Supportive therapy (IV saline and vital sign monitoring) was initiated and liver enzymes, bilirubin levels, and prothrombin times were monitored daily. All had returned to normal values in 2 weeks. CONCLUSIONS: MDMA, or the recreational drug ecstasy, might be responsible for acute hepatitis and/or acute liver failure, particularly in young people. Physicians might need to be alert to the possibility of ecstasy-induced liver damage occurring in younger patients, although the presence of other hepatotoxins and alternative diagnoses requires exclusion. The use of this drug should be investigated in young patients with severe hepatitis of unknown origin.
