Study objective: The primary aim of this study was to investigate whether IMA levels are helpful in the diagnosis of pulmonary embolism (PE). The secondary aim was to determine whether IMA was more effective alone or in combination with clinical probability scores in the diagnosis of PE. Thirdly, the sensitivity and specificity of IMA is compared with D-dimer both with and without clinical probability scores in patients with suspected PE. Methods:Consecutive patients presenting to the emergency department with suspected PE were prospectively recruited, and healthy volunteers were also enrolled as controls. D-dimer and IMA levels were measured for the entire study group. Wells and Geneva scores were calculated and s-CTPA was performed on all suspected PE patients. Results:The study population consisted of 130 patients with suspected PE and 59 healthy controls. Mean IMA levels were 0.362 ± 0.11 ABSU for Group A, the PE group (n = 75); 0.265 ± 0.07 ABSU for Group B, the non-PE group (n = 55); and 0.175 ± 0.05 ABSU for Group C, the healthy control group (p < 0.0001). At a cut-off point of 0.25 ABSU, IMA was 93% sensitive and 75% specific in the diagnosis of PE. PPV was 79.4% and NPV was 78.6%. Mean D-dimer levels were 12.48 ± 10.88 μg/ml for Group A; 5.36 ± 7.80 μg/ ml for Group B and 0.36 ± 0.16 μg/ml for Group C (p < 0.0001). The D-dimer cut-off point was 0.81 μg/ ml with a sensitivity of 98.9% and a specificity of 62.7%, PPV of 69.4% and NPV of 83.3%. The use of IMA in combination with Wells and Geneva clinical probability scores was determined to have a positive impact on these scores' sensitivity and negative predictive values. Conclusion:IMA is a good alternative to D-dimer in PE diagnosis in terms of both cost and efficiency. Used in combination with clinical probability scores, it has a similar positive effect on NPV and sensitivity to that of D-dimer. The PPV of IMA is better than D-dimer, but it is still unable to confirm a diagnosis of PE without additional investigation.

The water pipe is a means of tobacco consumption widespread in Turkey and Arab countries. We present two patients brought to our emergency department due to a syncopal attack secondary to carbon monoxide toxicity following water pipe use. This rare form of poisoning should be borne in mind by emergency physicians as a differential diagnosis in water pipe smokers. Water pipes should be used where there is adequate ventilation.

IntroductionLithium overdose can be associated with cardiac toxicity, especially in those with underlying heart disease. Toxic levels of serum lithium are associated with cardiotoxic effects ranging from simple ECG disorders to dysrhythmias, cardiomyopathy and even acute myocardial infarction (AMI). This report describes a patient with AMI accompanied by high blood levels of lithium.Case PresentationA 62-year-old woman was admitted to the emergency department due to weakness and acute chest pain. Her ECG revealed ST elevation in leads DI, aVL and V5-6, with a ventricular rate of 80 bpm. Blood chemistry and complete blood count were within normal limits. The patient’s blood lithium level was measured as 2.3 mmol/L (N: 0.5 - 0.8 mmol/L), and her troponin I level was 0.892 ng/mL (N: 0 - 0.01 ng/mL). Coronary angiography produced normal findings, concurrent with the resolution of electrocardiographic abnormalities following elimination of lithium. The clinical course in the intensive care unit was uneventful and the patient was discharged on the seventh day.ConclusionsLithium intoxication should be considered in the differential diagnosis, especially in elderly patients on lithium therapy who are admitted to the emergency department with chest pain.

Objective: Acute abdominal pain is a common cause of admission to the emergency department. Differential diagnosis of abdominal pain is not easy for the emergency physician. In this study, the results of physical examination, blood biochemical analysis and radiological imaging in patients presenting to the emergency department with abdominal pain were evaluated. These findings were compared with the literature. Material and Methods: This study was designed as a cross-sectional descriptive study. One hundred and sixty-six patients were included. Patient physical examination findings, amylase, D-dimer and leukocyte values and radiological and surgical findings were evaluated. Results: All patients had abdominal physical examination findings. Seventy-two (43.4%) patients had only abdominal sensitivity, 33 (28%) patients showed gall bladder pathology by ultrasound and no pathology was found in 36 patients (30.7%). A mass was determined in three (8.1%) of 37 (22.3%) patients, appendicitis in four (10.8%), gall bladder pathology in three (8.1%), ileus-volvulus in four (10.8%) and mesenteric ischemia in six (16.2%) patients who were examined by abdominal tomography. Conclusion: Despite advances in imaging and laboratory techniques, the great majority of cases with acute abdominal pain cannot be definitively diagnosed, as in this study, and are evaluated as non-specific abdominal pain. The fact that selected cases are transferred to the center where the investigation is performed may create a discrepancy with the literature. In this study, the frequency of gall duct-related diseases was higher than in the literature and cases of acute appendicitis were much less frequent. (JAEM 2012; 11: 212-5)

Objectives Diagnosis of pediatric patients presenting to the Emergency Department with acute abdominal pain is not always easy. The purpose of this study was to investigate the effectiveness of irisin, a peptide hormone with reactivity shown in the appendix and neutrophils, in the differential diagnosis of pediatric patients with acute abdominal pain. Methods 162 subjects consenting to participate, including 112 patients presenting to the Pediatric Emergency and Pediatric Surgery clinics with acute abdominal pain and 50 controls, were enrolled in the study. Blood was collected from all patients following initial examination for irisin, WBC, and CRP investigation. Results Mean irisin levels in cases of acute appendicitis (AA) and perforated appendicitis (PA) were statistically significantly higher compared to nonspecific abdominal pains and the control group. No statistically significant difference was observed in irisin levels between AA and PA cases. WBC and CRP levels were also significantly higher in cases of AA and PA compared to nonspecific abdominal pains. Conclusions Differential diagnosis of acute abdominal pains in children and deciding on surgery are a difficult and complex process. Our study shows that irisin can be a useful biomarker in differentiating AA and PA from other acute abdominal pains in children.

Prothrombin complex concentrates (PCC) has long been used to reverse vitamin K antagonists (VKA)-induced coagulopathy rapidly and safely. However, its use in trauma-induced coagulopathy (TIC) in patients not using VKA drugs is yet to be elucidated. This article is a narrative review and analysis of the most recent literature to analyse consequences, and intended effects associated with this treatment modality in TIC. Utilization of PCC was addressed in the literature data found by searches of databases. The indications, efficacy and outcomes associated with the use of the product were reviewed in the articles. Some studies point out promising results with respect to PCC use to overcome the VKA-related coagulopathy in victims of trauma. PCC may be a viable option for resuscitation in emergency and critical care in the management of severe hemodynamic deterioration induced by trauma, despite contradictory findings in the literature.

Background and Objectives: The perfusion index (PI) indicates the ratio of pulsatile blood flow in peripheral tissue to non-pulsatile blood flow. This study was performed to examine the blood perfusion status of tissues and organs of patients using synthetic cannabinoids (SCs). Materials and Methods: The records of patients aged 17 or over presenting to the adult emergency department due to SC use between 1 January 2016 and 31 December 2017 were examined in this single-center, retrospective, cross-sectional study. Examined factors included time from consumption of SC to presentation to the emergency department, as well as simultaneously determined systolic and diastolic blood pressures, heart rate (beats per min), Glasgow Coma Score (GCS), and PI values. Patients were divided into two groups, A and B, depending on the amount of time that had elapsed between SC consumption and presentation to the emergency department, and statistical data were compared. Results: The mean PI value in Group A was lower than that in Group B. Therefore, we concluded that peripheral tissue and organ blood perfusion is lower in the first 2 h following SC consumption than after 2 h. Systolic, diastolic, and mean arterial blood pressure and mean GCS values were also statistically significantly lower in Group A than in Group B. Conclusions: A decreased PI value may be an early sign of reduced-perfusion organ damage. PI is a practical and useful parameter in the early diagnosis of impaired organ perfusion and in monitoring tissue hypoxia leading to organ failure.
