Experimental Study: The Effect Of 20% Intralipid Emulsion Therapy In Cerebral Ischemic Reperfusion.

BACKGROUND: This experimental study was conducted to investigate the effect of 20% Intralipid Emulsion (ILE) treatment on Cerebral Ischemia Reperfusion Injury (CIRI) after reperfusion in acute ischemic stroke. METHODS: In this experimental study, seven rats without any intervention (control group), seven rats (sham group) for which CIRI was created after the common carotid artery was ligated for 2 hours, and seven rats who were treated with 20% ILE after CIRI (CIRI + ILE group) were sacrificed after 24 hours, and histopathological findings were investigated. RESULTS: In rats that were not treated after CIRI, 52.7% had level-1, 32.7% had level-2. and 14.5% had level-3. histopathological findings. While 72.2% of the rats treated with ILE had level-1 and 27.8% had level-2 findings, no level-3 histopathological findings were detected in any of the rats. While no signs of coagulative necrosis, spongiosis of surrounding tissue and polymorphonuclear leukocytes were observed histopathological in any of the rats given ILE, there was no macrophages finding in 85.6% of the rats. ILE treatment also reduced the histopathological findings of eosinophilic neurons, astrogliosis, neovascularization, vascular thrombosis and mononuclear inflammatory cells. CONCLUSION: This study showed that 20% ILE treatment reduces the histopathological damage seen in cerebral ischemia and CIRI.

Evaluation of bio-psycho-social and socio-cultural problems of Syrian elderly living in Turkey.

BACKGROUND: Older persons are among the vulnerable groups most affected by war and migration due to physical weakness, illness, social environment, and cultural adaptation difficulties. AIMS: The aim of this study is to determine the economic, biopsychosocial, and socio-cultural problems of the older Syrians living in Turkey. METHODS: Convergent mixed design was used within the scope of the research. For the qualitative phase of the research, 19 older persons migrants were interviewed. A semi-structured interview form was used to collect data in the interviews. For the quantitative phase of the research, 432 participants were reached. In order to collect data, Geriatric Depression Scale (GDS-15) and Socio-cultural Adaptation Scale (SCAS-R) were used together with the demographic information form. RESULTS: The mean age of the participants was 66.2 ± 7.10 (Min: 60; Max: 91), the majority (87%) between the ages of 60 to 74 and 53.2% were male. The mean SCAS-R score of the older Syrians was 2.48 ± 0.88 (Min: 1; Max: 5) and the mean GDS-15 was 2.63 ± 3.84 (Min: 0; Max: 15). About 22.7% of older Syrian participants had mild or severe depressive symptoms. Experienced traumatic events, changing economic situation, and family relationships affected both physical and mental health of the older persons. The socio-cultural adaptation of the older persons was affected by language, temporary protection, and exposure to exclusion. The Older Syrians, who lacked information on social services, were experiencing problems with nutrition, clothing, bill payment, and rent due to economic problems. However, they mostly did not want to return to Syria because their living order in Syria was deteriorating and they were afraid. CONCLUSION: Syrian elderly immigrants living in Turkey have biopsychosocial, economic, and cultural problems. National and international support programs and policies should be developed for elderly Syrian refugees who are expected to live in Turkey unless a safe living environment is provided.

Elderly trauma patients and the effect of trauma scores on hospitalization decision.

Objectives: Hospitalization, mortality and trauma scores are important in trauma patients aged ≥65 years. The present study aimed to investigate the use of trauma scores in the prediction of hospitalisation and mortality in trauma patients aged ≥65 years. Material and Methods: Patients aged ≥65 years who presented to the emergency department with trauma over a one-year period were included in the study. Baseline data of the patients together with their Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), Injury Severity Score (ISS), hospitalisation and mortality were analysed. Results: A total of 2264 patients were included in the study, of whom 1434 (63.3%) were women. The most common mechanism of trauma was simple falls. Mean GCS scores, RTSs and ISSs of the inpatients were 14.87 ± 0.99, 6.97 ± 0.343 and 7.22 ± 5.826, respectively. Furthermore, a significant negative correlation was found between the duration of hospitalisation and GCS scores (r= -0.158, p <0.001) and RTSs (r= -0.133, p <0.001), whereas a positive significant correlation with ISSs (r= 0.306, p <0.001) was observed. The ISSs (p <0.001) of the deceased individuals were significantly elevated, whereas their GCS scores (p <0.001) and RTSs (p <0.001) were significantly decreased. Conclusion: All trauma scoring systems can be used to predict hospitalisation, but the results of the present study suggest that the use of ISS and GCS in making the decision regarding mortality is more appropriate.

Lung ultrasound for the diagnosis of pneumonia in adults.

OBJECTIVE: To investigate the value of chest ultrasound in the diagnosis of pneumonia in adults. METHODS: The prospective observational cohort study was conducted at Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkey, from December 1, 2015,to March 1, 2016, and comprised suspected pneumonia patients aged >18 years. Sonographic pneumonia was defined as lung consolidation with air bronchograms. Treating clinicians were blinded to lung ultrasound results. All patients who were advised to undergo thoracic computerised tomography after physical examination were subjected to posteroanterior chest X-ray before the scan. Patients in whom pneumonia was detected in the scan underwent thorax ulstasonography according to Bedside Lung Ultrasound in Emergency protocol. Follow-up was done with medical record review to obtain the final diagnosis and antibiotic usage. Data was analysed using SPSS 22. RESULTS: Of the 125 patients, 61(48.8%) were male. The overall mean age was 73.9±14.6 years. In 97(77.6%) patients, pneumominal infiltration was detected by thorax ultrasound, and in 57(45.6%) the infiltration was detected with chest X-ray. CONCLUSIONS: Thorax ultrasound was found to be a helpful diagnostic method when performed according to the Bedside Lung Ultrasound in Emergency protocol.

Viral prevalence, clinical profiles and comparison of severity scores for predicting the mortality of adults with severe acute respiratory infections

Background/aim: The aim of this study was to determine the accuracy of severity scores for predicting the 28-day mortality among adults with severe acute respiratory infection (SARI) admitted to the emergency department. Materials and methods: This study included 159 consecutive adult patients with SARI admitted to the emergency department of a tertiary hospital. A standard form was filled out in order to record demographic information, clinical parameters, laboratory tests, and radiographic findings of the patients. CURB-65, PSI, SIRS, qSOFA, SOFA and APACHE II scores were compared between the survivor and nonsurvivor groups. Results: Of 159 patients included in the study, 38.4% were positive for respiratory viruses and 28.3% were positive for influenza viruses. 35.8% of the patients were admitted to an intensive care unit (ICU) and the mortality rate was 36.5%. The area under the receiver operating characteristic curve of CURB-65, PSI, SIRS criteria, qSOFA, SOFA and APACHE II scores were 0.717, 0.712, 0.607, 0.683, 0.755, and 0.748, respectively in predicting mortality and 0.759, 0.744, 0.583, 0.728, 0.741, and 0.731, respectively in predicting ICU admission. Conclusion: SOFA and APACHE II were more accurate than SIRS in predicting the 28-day mortality among adults with SARI. There was no significant difference among these scores in terms of other multivariate comparisons.

Effects of acetaminophen and mannitol on crush injuries in rats: An experimental study.

BACKGROUND: The present objective was to evaluate effects of acetaminophen and mannitol on renal function and histopathology in crush injuries. METHODS: Thirty-six rats weighing 370-400 g each were used. No surgery was performed on the first (control) group. The gastrocnemius muscle regions of each rat in the remaining 5 groups were compressed for 2 or 24 hours. In the 4th group, 100 mg/kg acetaminophen was intraperitoneally administered. In the 5th group, 1 g/kg mannitol was administered. In the 6th group, 100 mg/kg acetaminophen and 1 g/kg mannitol were administered. RESULTS: No statistically significant differences were observed among the treatment groups in terms of sodium, potassium, alanine aminotransferase (ALT), and average creatinine clearance values. Hydropic degeneration, tubular necrosis, presence of immunoperoxidase and myoglobin, tubulus epithelial cell degeneration, and presence of PAS-dyed material in tubular lumen was more prominently decreased in the acetaminophen group than the mannitol group. Improvement was observed in the group that was administered both drugs, compared to the mannitol-only group, though findings were still worse than those of the group administered acetaminophen only. CONCLUSION: In crush injuries, acetaminophen improves histopathological renal damage better than mannitol. When used in conjunction with mannitol, the toxic effect of acetaminophen on the liver is decreased.

N-terminal pro-B-type natriuretic peptide as a marker of blunt cardiac contusion in trauma.

Cardiac contusion is usually caused by blunt chest trauma and, although it is potentially a life-threatening condition, the diagnosis of a myocardial contusion is difficult because of non-specific symptoms and the lack of an ideal test to detect myocardial damage. Cardiac enzymes, such as creatine kinase (CK), creatine kinase MB fraction (CK-MB), cardiac troponin I (cTn-I), and cardiac troponin T (cTn-T) were used in previous studies to demonstrate the blunt cardiac contusion (BCC). Each of these diagnostic tests alone is not effective for diagnosis of BCC. The aim of this study was to investigate the serum heart-type fatty acid binding protein (h-FABP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), CK, CK-MB, and cTn-I levels as a marker of BCC in blunt chest trauma in rats. The eighteen Wistar albino rats were randomly allocated to two groups; group I (control) (n=8) and group II (blunt chest trauma) (n=10). Isolated BCC was induced by the method described by Raghavendran et al. (2005). All rats were observed in their cages and blood samples were collected after five hours of trauma for the analysis of serum h-FABP, NT-pro BNP, CK, CK-MB, and cTn-I levels. The mean serum NT-pro BNP was significantly different between group I and II (10.3 ± 2.10 ng/L versus 15.4 ± 3.68 ng/L, respectively; P=0.0001). NT-pro BNP level >13 ng/ml had a sensitivity of 87.5%, a specificity of 70%, a positive predictive value of 70%, and a negative predictive value of 87.5% for predicting blunt chest trauma (area under curve was 0.794 and P=0.037). There was no significant difference between two groups in serum h-FABP, CK, CK-MB and c Tn-I levels. A relation between NT-Pro BNP and BCC was shown in this study. Serum NT-proBNP levels significantly increased with BCC after 5 hours of the blunt chest trauma. The use of NT-proBNP as an adjunct to other diagnostic tests, such as troponins, electrocardiography (ECG), chest x-ray and echocardiogram may be beneficial for diagnosis of BCC.

To decide medical therapy according to ECG criteria in patients with supraventricular tachycardia in emergency department: adenosine or diltiazem.

UNLABELLED: The aim of this study is to investigate the effect of ECG criteria which are used for the distinction between AVNRT and AVRT for the choice of treatment in patients with Supraventricular Tachycardia (SVT). The 77 patients with narrow QRS complex SVT which was treated with Adenosine or Diltiazem in the Emergency Department were evaluated retrospectively. All 12-lead ECG during tachycardia were blindly reviewed according to ECG criteria (Pseudo-r` in V1, Pseudo-S-wave in the inferior leads, Visible P-wave, aVL notch) by a cardiologist and an emergency physician. In this study, while 59.6% of the patients returned to normal sinus rhythm (NSR) after the first dose 6 mg, 64.91% of them after the first dose 12 mg and 71.92% of them after the second dose of 12 mg adenosine, 95% of the patients returned to NSR after the 0.25 mg/kg diltiazem. The most visible ECG findings were visible P waves and the least visible ECG findings were Pseudo-S waves in the inferior leads. It was statistically significant between converted by adenosine to NSR and converted by diltiazem to NSR to the presence of visible P-wave and the aVL lead notch in their ECG findings. CONCLUSION: The rate of return to NSR through diltiazem was found higher than that of adenosine in narrow complex SVT patients. Also, diltiazem may be the first medication to be preferred in the presence of retrograt P wave and aVL notch in the ECG of the patients with narrow QRS complex stable SVT.

A comparison of the outcome of CPR according to AHA 2005 ACLS and AHA 2010 ACLS guidelines in cardiac arrest: multicenter study.

The aim of this study was to evaluate whether there is a difference in the return of spontaneous circulation (ROSC) and survival with sequel-free recovery rates between the patients who underwent cardiopulmonary resuscitation (CPR) according to 2005 and 2010 guidelines. This study was conducted in the Bakirköy Dr. Sadi Konuk and Kartal Lütfi Kirdar Training and Research Hospital between dates of October 2010 and 28 February 2011 after approval of Ethics Committee. In the first months of the study, CPR was performed according to AHA 2005 ACLS guidelines (Group-1), while CPR was performed according to AHA 2010 ACLS guidelines after November 2010 (Group-2). Patients were assessed for neurological deficit with Cerebral Performance Categories Scale. Mean age was found as 69.01±13.05 (minimum: 21, maximum: 92) in 86 patients included. Of the 33 patients underwent CPR in the Group 1, ROSC was achieved in 51.5%; and 6.1% of these patients were discharged. Of the 53 patients underwent CPR in the Group 2, ROSC was achieved in 37.7%; and 9.4% of these patients were discharged. Although the number of living patients in Group 2 was higher than Group 1, the difference was not found statistically significant (5 versus 2), (P>0.05). But, neurological outcomes were found better with 2010 compared to 2005 guidelines (3/7 versus 0/2 good cerebral performance). It was found that the 2005 CPR guidelines practices in ED were more successful than the 2010 CPR guidelines practices in ROSC, but less successful in the rate of discharge from hospital and neurological sequel-free discharge rate.

A model of complaint based for overcrowding emergency department: Five-Level Hacettepe Emergency Triage System.

BACKGROUND: To compare ESI Five-Level Triage System with 5-Level Hacettepe Emergency Triage System (HETS), which was developed for Overcrowded EDs in our country. METHODS: Over a period of six days, patients were assessed by a different ED staff everyday using HETS, then re-evaluated blindly by an emergency physician using HETS. Then patients were evaluated blindly for a third time by an independent, ESI-using emergency physician. RESULTS: Of the patients in the study, 133 were men, 175 were women and the average age was 44.41±18.033. Inter-rater agreement was 97.40% (Kappa=0.963) between HETS and HETS-Blind, 74.35% (Kappa=0.646) between HETS and ESI-Blind, 74.67% (Kappa=0.652) between HETS-Blind and ESI-Blind. Inter-observer agreement between the second emergency physician performing HETS-Blind and the first emergency physician, resident, or nurse was very good (Kappa=1.0). Intern doctor, non-medical secretary and paramedic were found to have almost very good agreement (Kappa=0.971; 0.935; 0.864, respectively). An overtriage of 7.25% and undertriage of 1.08% were found in HETS. CONCLUSION: Complaint-based HEST developed for overcrowded Eds is a triage system with a very good agreement between observations and observers. Low undertriage and overtriage ratios, and easy application by all staff from a non-medical secretary to the emergency physician.

Management of pneumothorax in emergency medicine departments: multicenter trial.

BACKGROUND: Pneumothorax is common and life-threatening clinical condition which may require emergency treatment in Emergency Medicine Departments. OBJECTIVES: We aimed to reveal the epidemiological analysis of the patients admitted to the Emergency Department with pneumothorax. MATERIAL AND METHODS: This case-control and multi-center study was conducted in the patients treated with the diagnosis of pneumothorax between 01.01.2010-31.12.2010. Patient data were collected from hospital automation system. According to the etiology of the pneumothorax, study groups were arranged like spontaneous pneumothorax and traumatic pneumothorax. RESULTS: 82.2% (n = 106) of patients were male and 17.8% (n = 23) of patients were female and mean age were 31.3 ± 20,2 (Minimum: 1, Maximum: 87). 68.2% (n = 88) of patients were spontaneous pneumothorax (61.36%, n=79 were primary spontaneous pneumothorax) and 31.8% (n = 41) of patients were traumatic pneumothorax (21.95% were iatrogenic pneumothorax). Main complaint is shortness of breath (52.3%, n=67) and 38% (n=49) of patients were smokers. Posteroanterior (PA) Chest X-Ray has been enough for 64.3% (n = 83) of the patients' diagnosis. Tube thoracostomy is applied to 84.5% (n = 109) of patients and surgery is applied to 9.3% (n = 12) of patients and 6.2% (n = 8) of patients were discharged with conservative treatment. Spontaneous pneumothorax showed statistically significant high recurrence compared with traumatic pneumothorax (P = 0.007). 4.65% of (n = 6) patients died. The average age of those who died (9.3 ± 19.9), statistically were significantly lower the mean age of living patients (32.4 ± 19.7) (t test, P = 0,006). 83.33% of the patients who died were neonatals and in the 0-1 years age group, and five of these patients were secondary spontaneous pneumothorax, and one of these patients were iatrogenic pneumothorax due to mechanical ventilation. CONCLUSIONS: Pneumothorax in adults can be treated by tube thoracostomy or surgically. Despite treatment, mortality of secondary and iatrogenic pneumothorax in newborns and 0-1 years age group is high.

The effect of Beta-aminopropionitrile and prednisolone on the prevention of fibrosis in alkali esophageal burns: an experimental study.

Objective. The aim of this study was to investigate the efficacy of beta-aminopropionitrile (BAPN) and prednisolone on the prevention of esophageal damage and stricture formation after caustic esophageal burn. Method. Twenty-eight rats were divided into four equal groups. In groups 1, 2, and 3, caustic esophageal burns were generated by applying NaOH to the 1.5 cm segment of the abdominal esophagus. Group 4 was for the sham. Normal saline to group 1, BAPN to group 2, and prednisolone to group 3 were administered intraperitoneally as a single daily dose. Results. Treatment with BAPN decreased the stenosis index (SI) and histopathologic damage score (HDS) seen in caustic esophageal burn rats. The SI in group 4 was significantly lower compared with groups 1, 2, and 3. Group 2 had the minimum SI value in corrosive burn groups. The differences related to SI between groups 1, 2, and 3 were not statistically significant. The HDS was significantly lower in group 4 compared with groups 1, 2, and 3. The HDS in group 2 was significantly lower compared with groups 1 and 3. Conclusion. This study demonstrated that BAPN was able to decrease the development of stenosis and tissue damage better than prednisolone.

Computed tomography pulmonary angiography in the diagnosis of acute pulmonary embolism in the emergency department.

This study was undertaken to evaluate the use of computed tomography pulmonary angiography (CTPA) in patients with pulmonary embolism (PE) who were followed in the emergency department (ED). The files and computer records of 850 patients older than 16 years of age who were seen in the Hacettepe University Hospital ED between April 10, 2001, and December 1, 2005, and who required CTPA for PE prediagnosis and/or another diagnosis, were studied retrospectively. PE was identified by CTPA in 9.4% of 416 women and in 5.8% of 434 men. A significant difference (P<.05) was noted in the women and men in whom PE was detected. The mean age of the patients was 58.13+/-17.88 y (range, 16-100 y). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for clinical susceptibility to PE among patients who underwent CTPA were assessed at 95.3%, 48.2%, 13%, and 99.2%, respectively. CTPA was done for different reasons: aortic aneurysm dissection (n=1), cough distinctive diagnosis (n=1), dyspnea distinctive diagnosis (n=6), chest pain distinctive diagnosis (n=3), PE prediagnosis (n=51), and other reasons (n=2). Also, sensitivity, specificity, PPV, and NPV were found to be 95.4%, 16.2%, 14.4%, and 96%, respectively, for D-dimer. CTPA, which is accessible on a 24-h basis in the ED, is a valuable tool for the diagnosis of PE.

The ill child in the emergency department and the accompanying people: a cross-sectional analysis.

OBJECTIVE: The objective of this study is to investigate relationship between the number of the family members visiting the emergency department with pediatric patients and patient characteristics such as age, insurance status, traumatic complaint, whether event was acute or not, and to estimate number of family members who had any time off from their work among this group. METHOD: A prospective cross-sectional study was performed using a questionnaire which included demographic characteristics, number of family members, number of family members who were taking hours off from work. In the 15-day period (1-15 August 2003), all persons who accompanied the children to the university-based PED (annual volume: 18,000) were asked to participate in the study. RESULTS: A total of 575 persons accompanied the 300 children seen in PED (1.92 persons per child). Number of persons accompanying the children was found to be inversely related to age (Pearson correlation, P = 0.000). Seventy-nine children (32.1%) of those with acute complaints had family members who took time off from their work, whereas 29 (53.70%) of those with chronic illnesses had such family members (P = 0.003). The mean number of family members of children who had been referred from another healthcare institution was 2.06 +/- 0.77, whereas the mean number of family members of patients who presented directly to the PED was 1.85 +/- 0.63 (P = 0.013). The mean number of family members of patients who had insurance for their child and those who do not have were 1.84 +/- 0.66 and 2.06 +/- 0.71, respectively, (P = 0.001). CONCLUSIONS: Numbers of family members were positively associated with a history of referral to another institution for the same reason, and inversely related to the parents' age and insurance status.
