Does MDR1 Analysis Predict Medical Therapy Modifications in Patients with Atrial Fibrillation?

OBJECTIVE: To evaluate the effects of multi-drug resistance gene (MDR1) gene factor which is significant in medicinereceptor relationship, on readmission to the emergency department (ED) and medical therapy modifications in patients with atrial fibrillation (AF) readmitting to the emergency department. STUDY DESIGN: Descriptive, analytical study. PLACE AND DURATION OF STUDY: Department of Emergency Medicine, Adnan Menderes University, Aydin, Turkey, from January 2016 to January 2017. METHODOLOGY: Fifty patients who did not have AF with rapid ventricular response, and 32 controls have been included in the study. Electronic recording system of the hospital was checked regularly to detect any readmission of these patients due to palpitation; and they were asked whether they had any ED readmission and any changes in medical therapy by calling them during the one-year period. Then, MDR1 1236TC, 2677TG and 3435TC gene analyses and medical treatment regimens of the patients after 1 year were compared. RESULTS: No significant differences were found neither between the study and the control group nor between the genders in the study group regarding the results of MDR1 gene analyses. Besides, there were no differences in medical treatment regimens compared to MDR1 gene analyses in the group with AF. There were no statistically significant differences in the results of MDR1 gene analysis in patients whose medical treatment regimen had been changed during the one-year period. CONCLUSION: MDR1 gene analyses did not have any significant effect on the development of AF, readmission to the ED and modification of the treatment regimenin the Turkish population.

Predicting critical duration and reversibility of damage in acute mesenteric ischemia: An experimental study.

BACKGROUND: The objective of the current study was to investigate the value of the ischemic biomarkers endothelial cell-specific molecule-1 (endocan) and signal peptide-CUB-EGF domain-containing protein-1 (SCUBE-1) in the diagnosis and assessment of earlystage and irreversible damage in acute mesenteric ischemia. METHODS: An experimental mesenteric ischemia reperfusion model was designed using 54 rats. Nine groups were created: Three sham groups [Groups I (30th minute), IV (2nd hour), and VII (6th hour)], in which only blood and tissue specimens were sampled; 3 ischemia groups [Groups II (30th minute), V (2nd hour), and VIII (6th hour)], in which blood and tissue specimens were sampled after ligation of the superior mesenteric artery (SMA); and 3 reperfusion groups [Groups III (30th minute), VI (2nd hour), and IX (6th hour)], in which blood and tissue specimens were sampled after declamping the SMA and reperfusion for 1 hour. SCUBE-1 and endocan samples obtained from blood and tissue were examined histopathologically. RESULTS: The SCUBE-1 level was higher in the ischemia groups when compared with the sham groups (p<0.05), and the endocan level was markedly different in the late ischemia (6th hour) group. When these 2 markers were used together to assess irreversible mesenteric damage in the histopathological examination, the sensitivity in distinguishing between reversible or irreversible damage was 94.1% with a specificity of 73.7%. CONCLUSION: The elevation of SCUBE-1 alone seems to be significant for predicting early mesenteric ischemia in laboratory rats. The combination of SCUBE-1 and endocan may be useful to detect irreversible intestinal damage.

The predictive value of the inflammatory markers P-selectin and MCP1 in determining the length of stay and 30-day survival in the differentiation of sepsis patients.

OBJECTIVE: Sepsis is the leading disease that is diagnosed late and still has a mortal course in emergency departments. The primary factors that will reduce both morbidity and mortality are early diagnosis and an early treatment approach. Therefore, in this study, P-selectin and MCP1 levels, which are known to be markers of inflammation, were examined in patients being followed up in intensive care. METHODS: Patients evaluated with a preliminary diagnosis of sepsis in the emergency intensive care unit between September 2015 and August 2016 were classified as having sepsis or infection according to the Q- SOFA criteria, and the P- selectin values were compared. RESULTS: In the sepsis group, GCS was determined as 13 (12-13), SBP 90 (80-110), tachypnea 24 (22-26), lactate 3.8 (0.6-16.0), MAP 70 (60-77), and LOS 16 days (9.5-20.3). In the ROC analysis, the sensitivity of P-selectin and MCP1 in the differentiation of patients with and without sepsis was 95.7%, and 73.8%, and the specificity was 97.8% and 73.8%, respectively. According to the cutoff values, the sensitivity and specificity in the prediction of patient mortality were 71.4% and 65.6% in P- selectin and 78.6% and 65.6% in MCP1. CONCLUSIONS: The P-selectin and MCP1 values in the emergency department can differentiate sepsis patients according to the Q-SOFA criteria and showed 30-day mortality at a significant level. Therefore, in patients with suspected sepsis in an emergency department, MCP1 can be of benefit to physicians in their decisions regarding LOS and transfer to intensive care.

Treatment methods following suicidal self-administration of IV organophosphate: What can additional lipid administration change?

Organic phosphor compounds are highly toxic and life-threatening compounds that are widely used in agriculture, households and gardens worldwide. While oral intakes are observed frequently, toxic effects can also be seen through contract or inhalation. However, toxic cases through the parenteral route have rarely been reported. We had three main aims: first, to present a male patient who self-administered 2ml of monocrotophos intravenously to commit suicide. Our second goal was to present the current multiple treatment methods, such as fast general support, antidote treatment, lipid emulsion treatment, and plasmapheresis along with the literature. Third, we aimed to emphasize that with these treatments, patients' intensive care needs, intermediate symptoms, and hospitalization periods can be decreased and thus mortality and morbidity increase can be prevented.

Can we predict agitation in patients with suicide attempts in the emergency department?

BACKGROUND: The agitation in patients presenting to the emergency department (ED) after suicide attempts is common and an important problem. OBJECTIVE: To establish whether we can predict agitated patients among suicide attempt patients in ED. METHODS: This is a cross-sectional observational study of adult suicide attempt events in ED. Information was collected prospectively on a specially designed data-collection form. Patients aged 16 years old and above who presented to the ED for care due to suicide attempts were included in the study. Suicide attempts were grouped as aggressive and non-aggressive attempts. RESULTS: A total of 533 patients were included. Forty-three of these patients had agitation in ED (8%). Non-aggressive suicide attempts were referred to psychiatry services more than aggressive ones (73.6%, n=345 vs 32.8%, n=21, P<0.0001). Agitation in ED and being male increased aggressive suicide attempt risk 3.5 (95% CI:1.6-7.6) and 3.2 times (95% CI:1.8-5.5), respectively. Agitation was statistically more frequent among these patients: those on antidepressant overdose, with previous suicide attempt; with aggressive suicide attempt; and those with confusion; and unconsciousness (P<0.05). CONCLUSION: Patients who attempted suicide and whose risk of harm to others included those with: antidepressant overdose, aggressive suicide attempt and the unconscious. Response teams should be prepared for these subgroups.

Prognostic value of neglected biomarker in sepsis patients with the old and new criteria: predictive role of lactate dehydrogenase.

OBJECTIVES: This study examined the pH, lactate dehydrogenase (LDH), and heart rate values on the first day of hospitalization in patients with a prediagnosis of sepsis and biomarkers that may predict mortality. METHODS: Patients hospitalized in an emergency intensive care unit with a diagnosis of systemic inflammatory response syndrome were classified as having sepsis (n = 28), septic shock (n = 8), or severe sepsis (n = 8) according to International Sepsis Guidelines (old criteria). Forty-four patients were classified as having sepsis (n = 4), septic shock (n = 30), or infection (n = 10) according to The Third International Consensus Definitions for Sepsis and Septic Shock (new criteria). The effects of these patients' laboratory values on survival between groups were compared. Significant values were evaluated by χ2 automatic interaction detection analysis. RESULTS: When the patients were categorized according to the new classification criteria, there was an increase in the number of septic shock patients and a decrease in the number of sepsis patients. In addition, 10 patients were removed from the sepsis category. There was a significant difference between ex and discharged patients in terms of heart rate, pH, sodium bicarbonate, lactate, and LDH (P= .007, P= .002, P= .034, P= .009, and P= .002, respectively). Based on a χ2 automatic interaction detection analysis of the significant values, pH, LDH, and heart rate were prominent predictors of prognosis. CONCLUSIONS: Systemic pH, LDH, and heart rate values may be used to determine the best time to discharge patients from intensive care to other, more affordable hospital units.

Characteristics of Patients Who Admitted to the Emergency Department Because of Burns Due to Dens Liquids Such as Hot Milk/Oil.

OBJECTIVE: Burn is the tissue damage on body caused due to various reasons. Although all burns caused by hot liquids are investigated as scalding burns, dense liquid burns (DLB) caused by such as milk and oil are different from other burns. The aim of this study was to report the properties of DLB. MATERIALS AND METHODS: Patients admitted to the Emergency Service of Atatürk University Hospital, with DLB from June 2003 to December 2008, were examined retrospectively. RESULTS: During the study, 28 DLB patients were admitted to the emergency service. The most common admission were found in autumn 28.6% (n=8), and in May and June, 17.9% (n=5). The frequency of burns on the right upper extremity was seen in 50% (n=14) of the patients. The burn degree of all patients was determined as 2(nd) degree. Seventy-five percent (n=21) of the patients were discharged, 14.3% (n=4) were hospitalized. None of the patients died. CONCLUSION: Dense liquid burns is a burn type that is commonly seen in women, absolutely causing 2(nd) degree burns, frequently reported in upper extremity and head/neck regions, and in contrast to other studies, in our region it is completely seen in patients living in city centre.

A rare complication of scorpion venom: atrial fibrillation.

Although the clinical findings of scorpion stings are often mild, they may lead to multiorgan failure and even cardiogenic shock. The toxin has both local and systemic effects. Local effects include edema, bruising(ecchymosis), and burning pain,whereas systemic effects include nausea,vomiting, hypotension or hypertension, cardiovascular toxicity, renal failure,and hemorrhage at different areas. The toxins have been implicated in a number of cardiac arrhythmias, including torsade de pointes, long QT syndrome, and atrial fibrillation. Here, we present a 90-year-old woman with no history of drug use or complaints due to dysrhythmias who developed atrial fibrillation after being stung by a scorpion.

The utility of cardiac magnetic resonance imaging in Kounis syndrome.

INTRODUCTION: Current diagnostic measurements used to assess myocardial involvement in Kounis syndrome, such as electrocardiography (ECG), cardiac enzymes, and troponin levels, are relatively insensitive to small but potentially significant functional change. According to our review of the literature, there has been no study using magnetic resonance imaging (MRI) on Kounis syndrome except for one case report. AIM: To identify the findings of dynamic contrast-enhanced magnetic resonance imaging (CE-MRI) in patients with Kounis syndrome (KS) type 1. MATERIAL AND METHODS: We studied 26 patients (35 ±11.5 years, 53.8% male) with known or suspected KS type 1. The patients underwent precontrast, first-pass, and delayed enhancement cardiac MRI (DE-MRI). Contrast enhancement patterns, edema, hypokinesia, and localization for myocardial lesions were evaluated in all KS type 1 patients. RESULTS: Contrast-enhanced magnetic resonance imaging demonstrated an early-phase subendocardial contrast defect, and T2-weighted images showed high-signal intensity consistent with edema in lesion areas. None of the lesion areas was found upon contrast enhancement on DE-MRI. The area of early-phase subendocardial contrast defect was reported as follows: the interventricular septum in 14 (53.8%) patients, the left ventricular lateral wall in 8 (30.7%), and the left ventricular apex in 4 (15.4%). CONCLUSIONS: Dynamic cardiac MR imaging is a reliable tool for assessing cardiac involvement in Kounis syndrome. Delayed contrast-enhanced images show normal washout in the subendocardial lesion area in patients with Kounis syndrome type 1.

Phenytoin intoxication with no symptoms correlated with serum drug level: a case study.

In high-dose intake of phenytoin, which is used frequently to treat epilepsy, nystagmus, diplopia, nausea-vomiting, lethargy, confusion, seizure, and coma can be observed. In recent studies on phenytoin intoxication, in which seizure and coma were observed in drug levels greater than 50 ug/mL. The serum phenytoin level of a patient, who consumed approximately 100 pcs of 100 mg phenytoin tablets in an effort to commit suicide, and who had no pathological finding in her neurologic examination, was 124 ug/mL. High drug level and the absence of toxic effect (or the absence of toxic effect correlated with the drug level) indicates that cytochrome P450 is functioning, but there can be a mutation in the MDR1 gene. In our case study, we report on phenytoin intoxication in a patient having a high level of phenytoin but no symptoms correlated with serum drug level, as supported by the findings in the literature.

Adult Intussusception: Clinical Experience from a Single Center.

Though frequently observed in children, intussusception is a rare state in adults. The treatment of intussusception in adults is different. In this trial, we have presented intussusception cases in adults that were treated and followed up in our department. The records of 31 adult intussusception cases surgically treated in our department between January 1993 and July 2012 were evaluated retrospectively. Among the 31 adult cases of intussusception that were treated during a period of 19 years, 10 were men, and 21 were women. The mean age was determined as 39.7 ± 5.3. The presentation symptom was abdominal pain in all the patients. Failure to pass gas or feces was observed in 23 patients (74.2 %); nausea and vomiting, in 22 patients (70.9 %); hematochezia, in 16 patients (51.6 %); and weight loss, in 3 patients (9.6 %). The mean duration of symptoms was 4.8 days. Abdominal tenderness was found in all the patients. Muscular defense and rebound tenderness were determined in 13 patients (41.9 %). Findings of intussusception were found in 80.9 % of patients examined by abdominal ultrasonography and in 63.1 % of cases examined by computerized tomography. Resection of the intussuscepted bowel segment was performed in 87 % of the patients. In conclusion, intussusception in adults is a rare clinical entity. Intussusception should be considered in the differential diagnosis in patients presenting with spasmodic abdominal pain, especially in cases with intestinal obstruction. The recommended surgical method is en bloc resection of the intussuscepted segment in cases suspected to carry a risk of malignancy.

Treatment with α-lipoic acid enhances the bone healing after femoral fracture model of rats.

This study investigated the fracture-healing effects of α-lipoic acid (α-LA), which was applied orally once daily in preventive treatment mode during 1 month after fracture induction. Rats were randomly divided into sham-operated group (group 1), femoral fracture control (group 2), femoral fracture + 25 mg/kg α-LA (group 3), and femoral fracture + 50 mg/kg α-LA (group 4). Rats in the experimental groups were orally administered 25 or 50 mg/kg α-LA once daily for 30 days starting from postoperative day 1. Thirty days postoperatively, the rats underwent X-ray imaging and were then euthanized for blood and tissue collection. Histopathological, biochemical, molecular, computed tomography (CT), and mechanical strength tests were performed on samples. The serum levels of osteocalcin (OC), osteopontin (OP), tumor necrosis factor alpha (TNF-α), and interleukin-6 (IL-6) did not differ significantly between groups 2 and 3. Serum OC, OP, TNF-α, and IL-6 levels in group 4 were significantly lower than those in group 3. From X-ray images, staging for fracture healing was scored as <2 in group 2, >2 in group 3, and >3 in group 4. In group 2, the average score of less than 2 suggests insufficient fracture healing; those of both the α-LA groups were >2, indicating progression of healing. Transforming growth factor beta (TGF-ß) messenger RNA (mRNA) levels were significantly higher in the sham group than in the femoral fracture control. Both doses of α-LA increased TGF-ß mRNA expression compared to the fracture group. CT results and biomechanical testing at 4 week after fracture demonstrated that α-LA has fastened bone healing, which was confirmed by stereological analyses in which 50 mg/kg α-LA increased the number of osteoclasts. Our findings indicate that α-LA supplementation promotes healing of femoral fractures in rats.

Non-operative management (NOM) of blunt hepatic trauma: 80 cases.

BACKGROUND: Liver is the most frequently injured organ upon abdominal trauma. We present a group of patients with blunt hepatic trauma who were managed without any invasive diagnostic tools and/or surgical intervention. METHODS: A total of 80 patients with blunt liver injury who were hospitalized to the general surgery clinic or other clinics due to the concomitant injuries were followed non-operatively. The normally distributed numeric variables were evaluated by Student's t-test or one way analysis of variance, while non-normally distributed variables were analyzed by Mann-Whitney U-test or Kruskal-Wallis variance analysis. Chi-square test was also employed for the comparison of categorical variables. Statistical significance was assumed for p<0.05. RESULTS: There was no significant relationship between patients' Hgb level and liver injury grade, outcome, and mechanism of injury. Also, there was no statistical relationship between liver injury grade, outcome, and mechanism of injury and ALT levels as well as AST level. There was no mortality in any of the patients. CONCLUSION: During the last quarter of century, changes in the diagnosis and treatment of liver injury were associated with increased survival. NOM of liver injury in patients with stable hemodynamics and hepatic trauma seems to be the gold standard.

Intracranial hemorrhage with electrocardiographic abnormalities and troponin elevation.

Electrocardiographic (ECG) abnormalities and cardiac troponin I elevation are seen in addition to the classic clinical symptoms and signs of subarachnoid hemorrhage (SAH). We aimed to show that, in patients with ST elevation, troponin elevation, and altered consciousness, the reason may be SAH. A 36-year-old man presented to emergency service with ECG abnormalities, high level of cardiac troponin I, and neurologic symptoms. In the patient's initial ECG, there were sinus arrhythmia, bradycardia, T-wave inversions inferiorly, and concave ST elevations in V1 to V4. Three hours later, his ECG showed increased ST-segment elevations with normal heart rate. The patient's troponin I value was 10 mg/L. Ejection fraction was 60%, and there were no wall motion abnormalities on echocardiography. Computed tomographic scan of the brain demonstrated SAH with falx sign and midline cerebellar hematoma (3 × 4 cm in size) in the occipital region. The patient died on the 10th day of follow-up because of severe metabolic acidosis, multiorgan failure, and bradycardia. Cardiac evaluation is recommended in patients with intracranial hemorrhage in many studies. In our opinion, if there are neurologic symptoms or signs in patients diagnosed as acute myocardial infarction with ECG changes and troponin elevation, requesting threshold of brain computed tomography should be low before the thrombolytic therapy.

Patient-staff safety applications: the evaluation of blue code reports.

OBJECTIVE: Blue code systems (BCS) are communication systems that ensure the most rapid and effective resuscitation when a patient is in respiratory or cardiac arrest. A hospital employee faced with the situation of a cardiopulmonary arrest (CPA) starts the system by dialing 6666 from any phone in the hospital. We created a five-person team that includes a doctor, nurse, anesthesia technician, stretcher officer and security guard. The purpose of this study is to share our experiences in initiating the use of the BCS in our hospital. MATERIALS AND METHODS: In our hospital, the records of calls that were made by Callvision BCS were analyzed retrospectively from May 2010 to the end of January 2011. RESULTS: A total of 474 calls were made using the blue code system. Of those calls, 402 (84.5%) were determined to be inappropriate calls. The remaining 72 calls were responded to. Of the 72 patients who were treated, 21 were discharged after they were hospitalized in the service or intensive care unit, 45 cases resulted in exitus, and 5 cases were referred to the Ataturk University faculty of medicine. CONCLUSION: The BCS has achieved its goal. The discharge rate of 29.5% that we achieved is a successful result.

Two questions for Kounis syndrome: can we use magnetic resonance imaging in the diagnosis and does ST elevation correlates with troponin levels?

Kounis syndrome (KS) is an acute coronary vasospasm after exposure to an allergen due to mast cell degranulation and existing mediators. Various drugs, conditions, and environmental exposures can cause KS. We presented 2 cases, 1 of whom had taken an antiflu drug (containing paracetamol, pseudoephedrine, and dextromethorphan). His electrocardiogram (ECG) showed inferior ST elevations (2 mm) with normal cardiac biomarkers. His cardiac magnetic resonance imaging showed hypokinesis and myocardial hibernation on apical septum and on the left ventricle. The second patient took a pill of naproxen sodium. The ECG showed 1-mm ST elevation in leads DII, V5, and V6. His troponin was markedly elevated. These cases showed that there seems to be no correlation with ECG and troponin levels in KS. In addition, for patients in whom KS type 1 is expected without troponin elevation, noninvasive cardiac magnetic resonance imaging study seems to be appropriate for the diagnosis of KS.

Wide central pontine, bulbar and thalamic myelinolysis with sequela.

Although cases of hyponatremia during pregnancy have been described, it has rarely been possible to show demyelination lesions in central pons, bulbus as well as thalamus, by imaging techniques. We report a case that developed extensive myelinolysis due to the "rapid" correction of hyponatremia as a result of hyperemesis gravidarum. Magnetic resonance imaging showed bilaterally symmetric hyper-intense areas in the thalamus and cerebral crus and symmetric hyperintense area in the central pons, with sparing of the rim. In the second day of hospitalization, probably as a result of expansion of myelinolysis, she was intubated and received mechanical ventilator due to bradypnea and a GCS scale of E1M4V2. She was extubated in 11(th) day of hospitalization and physical therapy was started. She was discharged in 30(th) day of hospitalization with a GCS of 15. But she was tetraparetic (2/5). In the 3(rd) month of follow up, her quadriparesis improved to paraparesis in lower extremities (3/5). Her follow up examinations in the first year did not change although physical therapies go on. She delivered a normal child.

Factors affecting the B-type natriuretic peptide levels in stroke patients.

INTRODUCTION: This study aims to evaluate the relationship between increased B-type natriuretic peptide (BNP) levels in stroke patients and clinical parameters such as age, sex, medical history, blood pressure, Glasgow Coma Score (GCS) and National Institutes of Health Stroke Scale (NIHSS). MATERIALS AND METHODS: This is a prospective study of 123 stroke patients at the Emergency Department. The patients were divided into 3 groups according to the NIHSS scores. The analysis of the mean difference between continuous variables and plasma BNP levels was assessed using the Mann-Whitney and Kruskal-Wallis. Spearman correlation analysis was performed for BNP and other clinical parameters. RESULTS: The BNP levels of patients who had a medical history of hyperlipidaemia, chronic obstructive pulmonary disease, diabetes mellitus and coronary artery disease were significantly higher than in patients without these diseases. Patients who had atrial fibrillation (AF) in their electrocardiography had significantly higher BNP levels than patients with sinus rhythm. A positive correlation was found between plasma BNP levels with age, blood urea nitrogen (BUN) and NIHSS and a negative correlation was found between plasma BNP levels and GCS. There was a significant difference between the BNP levels of NIHSS groups. CONCLUSION: We consider that plasma BNP levels could help us in interpreting the general clinical severity, functional capacity and clinical progress of stroke patients at the time of admission in the Emergency Department. In evaluating the high BNP levels in stroke patients, we must keep in mind that age, AF, BUN and medical history can affect the BNP levels.
