Predicting of neuropsychosis in carbon monoxide poisoning according to the plasma troponin, COHb, RDW and MPV levels: Neuropsychoses in carbon monoxide poisoning.

OBJECTIVE: Carbon monoxide (CO) poisoning is very common worldwide. In this study, we aimed to evaluate the predictivity of neuro psychosis in carbon monoxide poisoning by the admission levels of red cell distribution (RDW), mean platelet volume (MPV) and troponin I levels which can be measured quickly and easily in the emergency department (ED). PATIENTS AND METHODS: This single center observational study included a total of 216 consecutive patients who presented to the ED due to CO poisoning between January 2009 and December 2013. The diagnosis of CO poisoning was made according to the medical history and carboxyhemoglobin (COHb) level of >5%. According to the carboxyhemoglobin levels, the patients were classified as mildly (COHb < 20%) and severely poisoned (COHb > 20%). In addition, patients were divided into 2 groups, i.e., those with positive (>0.05 ng/mL for our laboratory) and negative (<0.05 ng/mL for our laboratory) troponin levels. RESULTS: Patients mean age was 52.58 ±â€¯10.58. 57.9% of the patients had high troponin levels and 51.9% were poisoned severely according to COHb levels. Patients with positive troponin and COHb had longer CO exposure time and higher neutrophil, lymphocyte, mean platelet volume (MPV), COHb and red cell distribution width (RDW) levels at the index admission following CO poisoning than patients with negative troponin (p < 0.05). Age, COHb level, CO exposure time, MPV and RDW (p = 0.001, p < 0.05) remained associated with an increased risk of troponin positivity following adjustment for the variables that were statistically significant. CONCLUSIONS: In patients presenting to the ED with CO poisoning, RDW and MPV can be helpful for risk stratification of neuropsychosis.

Risk of late appearance of acute myocardial infartion after carbon monoxide (CO) intoxication.

BACKGROUND: After acute carbon monoxide intoxication, there may be a higher risk for late adverse cardiac events. However, these patients are usually not followed to monitor the appearance of these effects. AIM: To follow patients seen at an emergency department for carbon monoxide intoxication, monitoring the appearance of myocardial infarction. To assess the predictive value for such complication of serum troponin, carboxyhemoglobin, and procalcitonin levels at the moment of intoxication. MATERIAL AND METHODS: We followed 237 patients receiving emergency care for carbon monoxide intoxication, with a serum carboxyhemoglobin of 5% or more, between 2010 and 2012. Levels of procalcitonin and troponin I were measured. Patients were followed for five years after the intoxication. RESULTS: During the follow up period, 35 patients had a myocardial infarction. These patients had significantly higher carboxyhemoglobin, procalcitonin and troponin I levels at the moment of the intoxication than their counterparts who did not had a myocardial infarction in the follow up. A logistic regression analysis showed that age, carboxyhemoglobin levels, procalcitonin, troponin 1 and length of CO exposure were associated with a higher risk of myocardial infarction. Procalcitonin, troponin and carboxyhemoglobin levels had a high sensitivity and specificity to predict the appearance of myocardial infarction, with high areas under the receiver operating characteristic (ROC) curves. CONCLUSIONS: In patients with CO intoxication, carboxyhemoglobin, troponin and procalcitonin levels at the moment of the intoxication are significant predictors of the late appearance of myocardial infarction.

COHgb levels predict the long-term development of acute myocardial infarction in CO poisoning.

BACKGROUND: There are several studies evaluating the cardiac effects of carbon monoxide (CO) poisoning during the acute period; however, the number of studies evaluating the long-term cardiac effects is limited. OBJECTIVE: The present study aimed to evaluate the effects of blood carboxyhemoglobin (COHb) levels, elevated due to CO poisoning on the long-term development of acute myocardial infarction (AMI). METHODS: This cross-sectional cohort study included a total of 1013 consecutive patients who presented to the emergency department (ED) due to CO poisoning, between January 2005 and December 2007. The diagnosis of CO poisoning was made according to the medical history and a COHb level of greater than 5%. In terms of AMI development, the patients were followed up for an average of 56 months. RESULTS: At the end of follow-up, 100 (10%) of 1013 patients experienced AMI. Carboxyhemoglobin levels at the time of poisoning were higher among those who were diagnosed with AMI compared to those who were not (55%±6% vs 30%±7%; P<.001). Using a multivariate Cox proportional hazards model with forward stepwise method, age, COHb level, CO exposure time, and smoking remained associated with an increased risk of AMI after adjustment for the variables found to be statistically significant in a univariate analysis. According to a receiver operating characteristic curve analysis, the optimal cutoff value of COHb used to predict the development of AMI was found to be greater than 45%, with 98% sensitivity and 94.1% specificity. CONCLUSION: In patients presenting to the ED with CO poisoning, COHb levels can be helpful for risk stratification in the long-term development of AMI.

Higher cancer antigen 125 level is associated with the presence of permanent atrial fibrillation in systolic heart failure patients.

INTRODUCTION: Atrial fibrillation (AF) is a common arrhythmia in heart failure (HF). Recent studies have shown that serum cancer antigen-125 (CA-125) levels are elevated in HF, and high levels of CA-125 in HF patients with sinus rhythm have been shown to be associated with the development of new onset AF. However, the relation between CA-125 levels and the presence of AF in HF is unknown. In this study we investigated whether plasma CA-125 levels in patients with systolic HF could predict the presence of AF. METHODS: The study was a retrospective cohort design including 205 stable systolic HF patients who were selected during outpatient clinic visits and who had CA-125 measurement and an electrocardiogram within the last one month before admittance to cardiology clinic. Patients were classified into two groups based on the presence of AF (n = 67) or sinus rhythm (n = 138). RESULTS: The mean age of the patients was 68 ± 11 years. CA-125 levels were significantly higher in patients with AF than patients with SR [33 (3-273) vs 102 (7-296) U/ml, P < 0.001]. CA-125 level, presence of right ventricular dilatation, pericardial effusion, moderate to severe TR and MR, and left atrial diameter were found to be associated with the presence of AF in univariate analysis. In a multivariate logistic regression model, only the CA-125 level remained associated. Also, according to the ROC curve analysis, the optimal cut-off level of CA-125 for predicting AF was ≥ 91 U/mL with a specificity of 84% and a sensitivity of 54%. CONCLUSION: We have shown that the CA-125 levels can be used to predict AF in patients with systolic HF.

Hair-thread tourniquet syndrome originating from a haemangioma in an adult patient.

Hair-thread tourniquet syndrome is an emergency condition rarely encountered since its first description, and it may be potentially dangerous unless treated. The potential hazard of the condition stems from hair strands wrapping around and strangulating various body processes such as fingers, penis, or clitoris. In this paper we aimed to report the first case of hair-thread tourniquet syndrome affecting a haemangioma of an adult patient. A 68-year-old woman presented to emergency department for pain in the mass on her back. On physical examination, a haemangioma with a size of about 3x3 cm was noted on the right scapula. When inspected closely, it appeared edematous and strangulated, and there were hair strands wrapped to the bottom of the wound. The hair strands were removed and the strangulated haemangioma was excised.

Management of thoracic trauma in emergency service: Analysis of 1139 cases.

OBJECTIVE: Thoracic trauma is a common cause of significant morbidity and mortality. This study presents a series of thoracic trauma with the aim to assess epidemiologic features, distribution of pathologies, additional systemic injuries, diagnosis, management and outcome. METHODOLOGY: Between January 2007 and December 2011, all patients with thorax trauma admitted to the emergency service of our hospital were retrospectively reviewed with respect to age, gender, etiological factors, distribution of pathologies, additional systemic injuries, diagnosis, treatment modalities, referral and outcome. RESULTS: A total of 1139 patients with thorax trauma were included in the study. Of these, 698 (61.3%) were male and 441 (38.7%) were female, and the average age was 54.17±17.39 years. 1090 (95.7%) of the patients had blunt trauma, whereas 49 (4.3%) had penetrating trauma. Etiological factors were falls in 792 (69.5%), motor vehicle accidents in 259 (22.8%), animal related accidents in 39 (3.4%) and penetrating injuries in 49 (4.2%) patients. It was found that 229 (20%) patients had single, 101 (8.9%) had double, 5 (3%) had three or more, 10 (0.9%) had bilateral rib fractures and 19 (1.7%) had sternal fracture. Pneumothorax was diagnosed in 58 (5.1%) patients, whereas hemothorax, hemopneuomothorax and other system injuries were diagnosed in 36 (3.2%), 38(3.3%) and 292 (25.6%) respectively. In our series, thirteen patients (mortality rate 1.1%) died as result of hemorrhagic shock (n=8), respiratory distress (n=3) and severe multiple trauma (n=2). CONCLUSION: Although majority of the patients with thorax trauma receive treatment as outpatients; thoracic traumas may be a life threatening condition, and should be identified and treated immediately. Mortality varies based on etiological factors, additional systemic pathologies, capabilities of the hospital especially diagnostic and treatment facilities in emergency services. We believe that a multidisciplinary approach to the patients with severe thorax trauma, and the opportunities of emergency bedside thoracotomy in emergency services will significantly reduce the morbidity and mortality.

Effect of plasma carboxyhemoglobin level on gonadal hormone levels.

BACKGROUND: In emergency departments, carbon monoxide (CO) is a common cause of toxic poisoning. We aimed to determine the relationship between plasma carboxyhemoglobin (COHb) levels and late post-treatment gonadal hormone changes in CO poisoning. METHODS: The study included 237 patients older than 18 who presented to the Emergency Department due to CO intoxication between January 2008 and December 2016. Patients with a COHb level of less than 30% were classified as having mild-to-moderate disease, while those with a COHb level of more than 30% were classified as having severe disease. RESULTS: Of 41 (17%) patients with gonadal hormone change (GHC), 19 (46.3%) were females. In cases with GHC, the exposure time was 5.76±1.64 hours (P=0.001). COHb level was 50.46±4.43% in the severe group (P=0.001), while hormone levels were normal in women and men before CO poisoning. GHC within one month and two years after poisoning was significantly higher (P=0.001). There were 138 (58.2%) patients in the mild-to-moderate group, and 99 (41.8%) patients in the severe group. Of the gonadal hormones, LH2 (luteinizing hormone) was 13.54±3.40 mIU/mL, FSH2 (follicle-stimulating hormone) 16.69±4.35 mIU/mL, PRL2 (prolactin) 16.23±4.73 ng/mL, and TTN2 (testosterone) 644.06±120.40 (P=0.001). In addition, COHb was found to be 42.68±8.42% (P=0.001). In univariate and multivariate Cox regression analysis, gender, LH1, LH2, PRL2, TTN2 and COHb values were found to be prognostic signs in terms of endocrine gonadal hormone change (P<0.05). In the correlation of COHb level with GHC, positive moderate-strong correlation was found between LH2, FSH2, PRL2, TTN2 (P=0.001). CONCLUSIONS: In patients admitted to the emergency services due to CO poisoning, elevated COHb may help predict the risk for late gonadal hormone levels.

The Effect of Fetuin-A and Other Laboratory Paremeters on Prognosis and Mortality in Crimean-Congo Hemorrhagic Fever.

Background: Crimean-Congo Hemorrhagic Fever (CCHF) is a disease with high morbidity and mortality, which is an important health problem in the world. Therefore, we aimed to evaluate the effects of plasma fetuin-A (FA) level, which is a new parameter in terms of prognosis and mortality of CCHF. Methods: A total of 87 patients were included who presented to the Emergency Department, Bagcilar Training and Research Hospital, Istanbul, Turkey with the diagnosis of CCHF from Feb 1, 2019 to Feb 1, 2020. The patients were divided into three groups as tick bite, contact history, and endemic area travel according to the transmission type, and two groups according to the presence of mortality or not. The laboratory data of the patients were compared within these groups. Relationship of hemogram, C-reactive protein (CRP), D-Dimer, sedimentation, lactate, and FA levels between groups were evaluated. Results: The average age of the patients was 62.52±14.94 years and 27(31%) of them were women. Mortality rates were in 6(6.9%) patients from endemic areas (P=0.015). While the FA level of the mortality group was 171.6±30.0 mg/L, it was 230.3±25.0 mg/L in the survivors (P=0.001). There was a moderate and strong negative correlation of FA level with mortality, tick history, and hospitalization. In ROC curve analysis of mortality and FA levels, parameters were determined as sensitivity 97.4% and specificity 96.2%. Conclusion: In addition to FA levels, as anticipated by our hypothesis, lactate, CRP, and sedimentation values can be used to predict prognosis and mortality in cases of CCHF.

Association of carbon monoxide poisonings and carboxyhemoglobin levels with COVID-19 and clinical severity.

BACKGROUND: Coronavirus disease 2019 (COVID-19), which recently spread throughout the entire world, is still a significant health issue. Additionally, the most common cause of risky poisoning in emergency services is carbon monoxide (CO) poisoning. Both disorders seem to merit more research as they have an impact on all bodily systems via the lungs. AIM: To determine how arterial blood gas and carboxyhemoglobin (COHb) levels affect the clinical and prognostic results of individuals requiring emergency treatment who have both COVID-19 and CO poisoning. METHODS: Between January 2018 and December 2021, 479 CO-poisoning patients participated in this single-center, retrospective study. Patients were primarily divided into two groups for analysis: Pre-pandemic and pandemic periods. Additionally, the pandemic era was divided into categories based on the presence of COVID-19 and, if present, the clinical severity of the infection. The hospital information system was used to extract patient demographic, clinical, arterial blood gas, COVID-19 polymerase chain reaction, and other laboratory data. RESULTS: The mean age of the 479 patients was 54.93 ± 11.51 years, and 187 (39%) were female. 226 (47%) patients were in the pandemic group and 143 (30%) of them had a history of COVID-19. While the mean potential of hydrogen (pH) in arterial blood gas of all patients was 7.28 ± 0.15, it was 7.35 ± 0.10 in the pre-pandemic group and 7.05 ± 0.16 in the severe group during the pandemic period (P < 0.001). COHb was 23.98 ± 4.19% in the outpatients and 45.26% ± 3.19% in the mortality group (P < 0.001). Partial arterial oxygen pressure (PaO2) was 89.63 ± 7.62 mmHg in the pre-pandemic group, and 79.50 ± 7.18 mmHg in the severe group during the pandemic period (P < 0.001). Despite the fact that mortality occurred in 35 (7%) of all cases, pandemic cases accounted for 30 of these deaths (85.7%) (P <0.001). The association between COHb, troponin, lactate, partial arterial pressure of carbon dioxide, HCO3, calcium, glucose, age, pH, PaO2, potassium, sodium, and base excess levels in the pre-pandemic and pandemic groups was statistically significant in univariate linear analysis. CONCLUSION: Air exchange barrier disruption caused by COVID-19 may have pulmonary consequences. In patients with a history of pandemic COVID-19, clinical results and survival are considerably unfavorable in cases of CO poisoning.

Relationship of V1 Derivation Biphasic P Waves with Morbidity and Mortality in Myocardial Infarction Cases.

OBJECTIVE: To evaluate the biphasic P (V1bP) wave in lead V1 in terms of three-vessel disease (TVD), bypass, and mortality in patients with acute coronary syndrome. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Department of Emergency Medicine, University of Health Sciences, Bagcilar Training and Research Hospital, Turkey, between January 2018 and December 2019. METHODOLOGY: A total of 497 patients were admitted to the emergency department due to acute coronary syndrome. Patients were grouped as the right atrium and the left atrium according to the direction of the V1bP wave. Gensini score (GS), left ventricular ejection fraction (LVEF), TVD, bypass, and mortality rates were compared according to these groups. RESULTS: According to the atrial involvement of the patients, the median age was 66 (58-74) years, 220 (44.3%) females and 277 (55.7%) males. In the left atrial group in the V1bP wave, anterior myocardial infarction was the most common in 128 (41.8%) patients, mortality in 17 (5.6%), TVD in 69 (22.5%), and bypass in 13 (4.2%) patients. In the right atrial group, it was found that 127 (66.5%) patients had inferior myocardial infarction, 34 (17.8%) mortality, 66 (34.6%) TVD, and 19 (9.9%) bypass TVD; GS was 89 (80-117) points and LVEF was 45 (36-55)%. In addition, a significant relationship was found with mortality (p=0.019), bypass (p<0.001) and complications (p=0.043). Although the variables showed differences in acute coronary syndrome, mortality, LVEF, GS, mild and/or moderate correlations were found. CONCLUSION: V1bP wave can be a determining parameter for acute coronary syndromes in terms of TVD, bypass, and mortality. KEY WORDS: Emergency department, Biphasic p in lead V1, Three-vessel disease, Bypass, Mortality.

Emergency service results of central venous catheters: Single center, 1042 patients, 10-year experience.

BACKGROUND: Central venous catheterization is currently an important procedure in critical care. Central catheterization has important advantages in many clinical situations. It can also lead to different complications such as infection, hemorrhage, and thrombosis. It is important to investigate critically ill patients undergoing catheterization. AIM: To evaluate the characteristics, such as hospitalization, demographic characteristics, post-catheterization complications, and mortality relationships, of patients in whom a central venous catheter was placed in the emergency room. METHODS: A total of 1042 patients over the age of 18 who presented to the emergency department between January 2005 and December 2015 were analyzed retrospectively. The patients were divided into three groups, jugular, subclavian, and femoral, according to the area where the catheter was inserted. Complications related to catheterization were determined as pneumothorax, guidewire problems, bleeding, catheter site infection, arterial intervention, and sepsis. Considering the treatment follow-up of the patients, three groups were formed as outpatient treatment, hospitalization, and death. RESULTS: The mean age of the patients was 60.99 ± 19.85 years; 423 (40.6%) of them were women. Hospitalization time was 11.89 ± 16.38 d. There was a significant correlation between the inserted catheters with gender (P = 0.009) and hospitalization time (P = 0.040). Also, blood glucose, blood urea nitrogen, creatinine, and serum potassium values among the biochemical values of the patients who were catheterized were significant. A significant association was observed in the analysis of patients with complications that develop according to the catheter region (P = 0.001) and the outcome stage (P = 0.001). In receiver operating characteristic curve analysis of hospitalization time and mortality area under curve was 0.575, the 95% confidence interval was 0.496-0.653, the sensitivity was 71%, and the specificity was 89% (P = 0.040). CONCLUSION: Catheter location and length of stay are important risk factors for catheter-borne infections. Because the risk of infection was lower than other catheters, jugular catheters should be preferred at entry points, and preventive measures should be taken by monitoring patients closely to reduce hospitalization infections.

R/S ratio in lead II, and the prognostic significance of red cell distribution width in acute coronary syndrome.

BACKGROUND: In spite of developing medical technologies to discover the etiopathogenesis of diseases and developments in the treatment of coronary artery disease, acute coronary syndromes (ACS) continue to be the main cause of mortality and morbidity worldwide. New cardiac biomarkers and techniques are needed to help provide rapid diagnosis in order to evaluate risk in coronary artery patients. AIM: To evaluate the effects of R to S ratio (RSR) in the electrocardiograph of patients with ACS, from the point of the arising complication after myocardial infarction (MI), to three-vessel disease (TVD) and mortality. METHODS: The data of 1,296 patients with ACS, who presented to the emergency department of our hospital with chest pain between January 2014 and December 2018 and were admitted to the cardiology clinic, were retrospectively included in this cross-sectional cohort study. Patients with an RSR value less than I were assigned to group I, while those with an RSR value greater than I were assigned to group II. RESULTS: In our study, 466 (35.9%) of the 1,296 patients, 357 (38.3%) in group 1 and 109 (29.9%) in group 2, were female, with a mean age of 61.56 ± 9.42. ST-elevation MI 573 (44.2%), unstable angina (UA) 502 (38.7%) and non ST-elevation MI 220 (17%) were more prevalent in group I. Acute anterior MI 263 (20.3) in group I, and acute inferior MI 184 (14.2) in group II was higher. Ischemic heart failure was the most common complication. In group II, the red cell distribution width (RDW) was 15.42 ± 1.82, the gensini score was 48.39 ± 36.44, the left ventricular ejection fraction was 41.17 ± 10.41, the TVD was 111 (8.5), and the mortality rate was 72 (5.6), which was significantly higher than group I RDW; in MI with ST and non-ST-elevation, in TVD, mortality and complications were high and low in UA. In single and multivariate regression analyses, the variables were associated with ACS risk. CONCLUSION: RSR levels may be an auxiliary predictive value in ACS in terms of complications developing after MI, TVD, and mortality.

Can Fetuin-A, CRP, and WBC Levels Be Predictive Values in the Diagnosis of Acute Appendicitis in Children with Abdominal Pain?

Background: Acute appendicitis (AA) is the most common cause of emergency surgery. Therefore, perforation is common. Early diagnosis and new markers are needed. The aim of this study was to investigate the effects of plasma Fetuin-A (FA) levels in patients with an acute abdomen (AB). Material and Method: This prospective study included 107 patients younger than 16 years of age who were admitted to the emergency department for abdominal pain between January and December 2018. The patients who presented abdominal pain were divided into two groups as AA and other causes (OC) of AB. Patients with acute appendicitis; intraperitoneal, retrocolic/retrocecal, and appendicitis were divided into three groups. Additionally, the AA group was divided into two groups as perforated appendicitis and non-perforated appendicitis. Serum FA levels of the patients were evaluated in the emergency department. Results: In the AA group, C-reactive protein (CRP) and white blood cell (WBC) levels were higher, and FA levels were significantly lower than in the AB group. Intraperitoneal localization was 95.2% and perforation was frequent. When significant values in the univariate regression analysis for acute abdomen and perforation were compared in the multivariate regression analysis, CRP, WBC, and FA levels were found to be prognostic. Furthermore, decreased FA levels were associated with AA, while too greatly decreased FA levels were associated with the risk of perforation. Conclusion: Current diagnosis can be made by history, physical examination, laboratory, and imaging methods in appendicitis cases. While trying to diagnose AA in children, the FA, CRP, and WBC levels may be predictive values to identify risk factors.

A Fifteen-Year Analysis of Rare Isolated Fallopian Tube Torsions in Adolescent Children: A Case Series.

Isolated tubal torsions presenting to the emergency department are a very rare cause of pediatric acute abdominal pain. Since making the diagnosis early is of importance in terms of affecting tubal damage and fertility, we aimed to evaluate cases of isolated tubal torsions in light of the literature. This study included 10 patients under 18 years of age who presented to the emergency department with abdominal pain between January 2003 and December 2018. The mean age was 14.5 ± 1.43 years (range: 12-17 years). The demographic characteristics, surgical findings and techniques, and concomitant pathology results of these patients were retrospectively evaluated. The reason for presenting to the emergency department for the 10 patients included in the study was abdominal pain. The mean duration of hospital admission with pain was 4.97 days. The onset of pain was less than 24 h in seven patients (70%) and more than 24 h in three patients (30%). Of the patients, nine (90%) had tenderness in the lower abdominal quadrant, five (5%) had defense, and three (30%) had rebound. Nausea, vomiting and leukocytosis were present in 50% of the cases. Right and left tubal involvement of the cases was equal. Seven (70%) of the isolated tubal torsions were accompanied by paraovarian cysts. Eight patients (80%) underwent open surgery and two (20%) underwent laparoscopic intervention. Detorsion was performed on five (50%) patients and salpingectomy was performed on five (50%) patients. Isolated tubal torsion should be considered in children presenting with acute abdominal pain in early adolescence. Early diagnosis is important for the preservation of fertility.

Do MCHC, MPV, and Procalcitonin Levels Determine Prognosis in Acute Coronary Syndrome?

AIM: Acute coronary syndrome (ACS) continues to be the main cause of mortality and morbidity globally. The aim was to assess serum procalcitonin (PCT), mean corpuscular hemoglobin concentration (MCHC) and mean platelet volume (MPV) levels in terms of complications after myocardial infarctus, triple vein coronary artery disease (TVCAD), and mortality prediction. MATERIAL AND METHOD: This cross-sectional cohort study included 200 patients with ACS attending the emergency department of our hospital with chest pain and admitted to the cardiology clinic from January 2014 to December 2016. Patients were divided into 4 groups as inferior group, anterior group, NSTEMI group, and UA group according to diagnosis. These groups were compared in terms of complications occurring after MI, TVCAD, and mortality rates. RESULTS: There were significant differences in terms of complications forming after ACS, TVCAD, and mortality. The inferior subgroup had high PCT and MCHC levels and was found to have more complications developing and mortality compared to other groups. Patients with high PCT and MPV values were identified to have higher mortality and TVCAD. In the anterior subgroup, ischemic heart failure was higher compared to the other groups. In the interior, anterior, and non-ST elevated myocardial infarctus (NSTEMI) groups, the 0-, 6-, and 12-hour cTnI values were significantly higher compared to the UA group, while the anterior group had a significantly higher 12-hour cTnI value compared to the NSTEMI group. Correlation analysis for PCT, MCHC, and MPV with complications developing after MI, mortality, and TVCAD found positive and statistically significant correlations. CONCLUSION: High PCT, MCHC, and MPV levels in acute coronary syndrome may be beneficial predictive values in terms of complications that may develop, TVCAD, and mortality.

Risk of late appearance of acute myocardial infartion after carbon monoxide (CO) intoxication / Riesgo de aparición de infarto agudo de miocardio en el largo plazo después de una intoxicación por monóxido de carbono (CO)

ABSTRACT Background: After acute carbon monoxide intoxication, there may be a higher risk for late adverse cardiac events. However, these patients are usually not followed to monitor the appearance of these effects. Aim: To follow patients seen at an emergency department for carbon monoxide intoxication, monitoring the appearance of myocardial infarction. To assess the predictive value for such complication of serum troponin, carboxyhemoglobin, and procalcitonin levels at the moment of intoxication. Material and Methods: We followed 237 patients receiving emergency care for carbon monoxide intoxication, with a serum carboxyhemoglobin of 5% or more, between 2010 and 2012. Levels of procalcitonin and troponin I were measured. Patients were followed for five years after the intoxication. Results: During the follow up period, 35 patients had a myocardial infarction. These patients had significantly higher carboxyhemoglobin, procalcitonin and troponin I levels at the moment of the intoxication than their counterparts who did not had a myocardial infarction in the follow up. A logistic regression analysis showed that age, carboxyhemoglobin levels, procalcitonin, troponin 1 and length of CO exposure were associated with a higher risk of myocardial infarction. Procalcitonin, troponin and carboxyhemoglobin levels had a high sensitivity and specificity to predict the appearance of myocardial infarction, with high areas under the receiver operating characteristic (ROC) curves. Conclusions: In patients with CO intoxication, carboxyhemoglobin, troponin and procalcitonin levels at the moment of the intoxication are significant predictors of the late appearance of myocardial infarction.

Antecedentes: Después de una intoxicación con monóxido de carbono, hay un mayor riesgo de desarrollar problemas cardiovasculares a largo plazo. Sin embargo, estos pacientes no son seguidos habitualmente para evaluar la aparición de estos eventos. Objetivo: Efectuar un seguimiento de pacientes que han sufrido una intoxicación con CO, evaluando la aparición de infarto del miocardio. Evaluar el valor de los niveles de troponina, carboxihemoglobina y procalcitonina para predecir la aparición de estos eventos. Material y Métodos: Seguimos 237 pacientes que fueron atendidos de urgencia por una intoxicación con CO, con niveles de carboxihemoglobina de 5% o más, entre 2010 y 2012. Se midieron los niveles de procalcitonina, troponina 1 y carboxihemoglobina y los pacientes fueron seguidos por cinco años después de la intoxicación. Resultados: Durante el seguimiento, 35 pacientes tuvieron un infarto al miocardio. Estos pacientes tenían niveles significativamente más altos de procalcitonina, troponina 1 y carboxihemoglobina al momento de la intoxicación, que los pacientes que no tuvieron un infarto durante el seguimiento. Una regresión logística mostró que la edad, carboxihemoglobina, procalcitonina, troponina y la duración de exposición a CO se asociaron a un mayor riesgo de infarto. Procalcitonina, troponina 1 y carboxihemoglobina tuvieron una alta sensibilidad y especificidad para predecir la aparición de infarto, con áreas bajo la curva ROC (receiver operating characteristic) elevadas. Conclusiones: En pacientes con intoxicación por CO, la carboxihemoglobina, procalcitonina y troponina son predictores significativos de la aparición de infarto agudo de miocardio en el largo plazo.

Comparison of trauma scores for predicting mortality and morbidity on trauma patients.

BACKGROUND: In this study, we compared the anatomical, and physiological scoring systems trauma revised injury severity score (TRISS), revised trauma score (RTS), injury severity score (ISS), new injury severity score (NISS) to each other, to find out the most accurate and reliable trauma score for the risk classification of morbidity and mortality among the trauma patients. METHODS: This is a cross-sectional study, which included 633 patients who admitted to our University Hospital Emergency Department during an 8-month period due to trauma. All blunt and penetrating traumas (traffic accident, assault, etc.) patients above 16 years were included. RESULTS: Arrival time trauma scores (ISS, NISS, RTS, and TRISS) of the patients was calculated. Mean trauma score for the mortality prediction was calculated, and the p value was equal for all (p=0.001). Trauma scores were also analyzed for the hospitalization time in intensive care unit (ICU). While NISS, RTS, and TRISS values were significant (p=0.048, p=0.048, and p=0.017, respectively), ISS value was not significant (p=0.257) for predicting the ICU hospitalization time. Only TRISS was a good predictor for the mechanically ventilation time in ICU patients (p=0.01). CONCLUSION: In conclusion, we determined that the anatomical trauma scores (NISS, ISS) predicted the hospitalization and ICU necessities better, whereas TRISS, an anatomo-physiological trauma score, defined the ICU hospitalization and mechanically ventilation time better.
