Value of plasma neutrophil gelatinase-associated lipocalin (NGAL) in distinguishing between acute kidney injury (AKI) and chronic kidney disease (CKD).

OBJECTIVE: In this study, we aimed to determine whether plasma NGAL levels could be used as a biomarker for distinguishing between AKI and CKD in emergency medicine. MATERIALS AND METHODS: This prospective study was conducted at the ED of a training and research hospital over a six-month period in 2015. Three groups were defined: an AKI group - defined as a new onset of at least a 1.5-fold or ≥0.3 mg increment increase of SCr values from the normal baseline, a stable CKD group - only included presence of stages 2 through 4 of CKD according to the National Kidney Foundation's KDIGO 2012, and a control group. After the initial evaluation of patients, venous blood samples were taken for routine biochemical, counter blood cell, and plasma NGAL measurement at admission. RESULTS: A total of 25 patients with AKI, 22 patients with stable CKD, and 22 control subjects were enrolled. Level of plasma NGAL in AKI group was higher than those of the stable CKD group (median: 794 ng/ml IQR: 317-1300 & 390 ng/ml IQR: 219-664, p < 0.001). AUC was measured as 0.68 (p = 0.02, 95% CIs: 0.54-0.84) to assess the utility of plasma NGAL levels at varying cut-off values for distinguishing between AKI and CKD. For plasma NGAL, the best cut-off level was found to be 457 ng/ml (sensitivity: 72.0%, specificity: 64%). CONCLUSION: This study has clearly demonstrated that plasma NGAL levels were higher in AKI patients than in CKD patients. However, in clinical practice, the use of plasma NGAL levels to distinguish between AKI and CKD is limited.

Diagnostic value of appendicular Doppler ultrasonography in acute appendicitis.

BACKGROUND: Acute appendicitis is one of the most common causes of acute abdominal pain prompting emergency department (ED) visits. It is critical for the physicians to promptly and accurately diagnose acute appendicitis. The present study aimed to evaluate the diagnostic efficacy of Doppler ultrasonography (USG) in patients with acute appendicitis and compare this new method with other commonly used radio-diagnostic tools. METHODS: All patients who were diagnosed with acute appendicitis at the Kecioren Training and Research Hospital ED and later underwent appendectomy between October 2012 and April 2013 were included in the study. Approval from the ethics committee was obtained for this prospective study. The patients' demographic information, physical examination findings, vital signs, Alvarado scores, and laboratory and radiological exam results were recorded. RESULTS: A total of 60 patients were enrolled in the study. In 46 of the 60 patients, diagnosis of acute appendicitis was confirmed by histopathology results, whereas 14 patients, diagnoses was not confirmed by lab tests. Doppler USG could detect 43 of the 46 patients as true positives, and it detected 2 of the 14 patients with negative lab results as false positives. For diagnosis of acute appendicitis, sensitivity of appendicular Doppler USG was 93%, specificity was 85%, accuracy was 91%, positive likelihood ratio was 6.5, and negative likelihood ratio was 0.08. CONCLUSION: Doppler imaging can offer a high level of diagnostic success in patients with acute appendicitis. Appendicular Doppler USG offers a rapid and easy application without the need to expose patients to contrast medium and is superior to both USG and computed tomography. Therefore, we recommend the use of appendicular Doppler imaging as the primary radiological exam in diagnosing acute appendicitis.

Comparing the success rates of standard and modified Valsalva maneuvers to terminate PSVT: A randomized controlled trial.

PURPOSE: The study aimed to detect whether modified Valsalva maneuver (VM) is more effective than the standard VM in terminating paroxysmal supraventricular tachycardia (PSVT). METHODOLOGY: This randomized controlled trial was conducted in the emergency department of a training and research hospital between Dec. 1, 2015 and Dec. 31, 2016. Participants were divided into two groups, randomly assigned standard VM or modified VM, as the first treatment with two-dimensional permutation blocks; in the order of arrival of the patients. In both groups; the determined procedure for standard or modified VM was repeated up to three times in patients whose PSVT did not convert to sinus rhythm. In both groups; if the maneuver was unsuccessful after three attempts, anti-arrhythmic medication was administered. The primary outcome was defined to compare the success rate of achieving sinus rhythm after standard VM or modified VM. RESULTS: Fifty-six patients were randomized to modified or standard VM with 28 patients in each treatment arm. Three of 28 patients (10.7%) in VM group and 12 of 28 patients (42.9%) in modified VM group were returned to sinus rhythm after intervention (p=0.007). The number of patients who needed rescue treatment was lower in the modified VM group - 16 (57.1%) of 28 versus 25 (89.3%) of 28 in the standard VM group (p=0.007). CONCLUSION: This study suggests that modified VM therapy was more effective than standard VM for terminating PSVT. The modified VM therapy also indirectly reduced the need for anti-arrhythmic medication and indirectly caused fewer side effects.

Effects of spinal immobilization at 20° on respiratory functions.

PURPOSE: The purpose of the study is to investigate whether spinal immobilization with a long backboard (LBB) and semirigid cervical collar (CC) at 20° instead of 0° conserve pulmonary functions, including forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio. METHODOLOGY: The study included 56 adult healthy volunteers. Volunteers were randomly divided into 2 groups, and those in the first group (group 1) had LBBs and CCs applied at 0° (n=30), whereas volunteers in the second group (group 2) had LBBs and CCs applied at 20° (n=26). All volunteers were given pulmonary function tests, which included FEV1 and FVC levels and FEV1/FVC ratios, while in the sitting position. Measurements were repeated at 0, 5, and 30 minutes. RESULTS: Results showed significant decreases in FEV1 and FVC values and FEV1/FVC ratios in group 1 and significant decreases in FEV1 values and FEV1/FVC ratios in group 2 (P<.001). However, FVC values were not decreased in group 2 when compared to basal levels taken while in a sitting position (P=.45). In addition, the study evaluated the amounts of decrease in the FEV1 and FVC levels and the FEV1/FVC ratios (ΔFEV1, ΔFVC, and ΔFEV1/FVC ratio). Results showed that ΔFEV1 values compared to basal levels and levels at 0, 5, and 30 minutes were all lower in group 2 than in group 1. However, ΔFEV1/FVC ratios were similar in both groups. CONCLUSION: The results of this and previous studies have shown that traditional spinal immobilization decreases respiratory function, whereas using spinal immobilization at 20° can reduce this decrease in function.

Predictors of Inhospital Mortality in Geriatric Patients Presenting to the Emergency Department With Ischemic Stroke.

AIM: To determine the most important predictors of inhospital mortality that could be assessed in geriatric patients presenting with ischemic stroke at admission to the emergency department(ED). METHODS: A retrospective cohort study was carried out in geriatric patients with ischemic stroke who were diagnosed in the ED. The primary outcome measure was determined as all-cause inhospital mortality after 30 days of ischemic cerebrovascular event. RESULTS: During the study period, 247 (35.7%) patients died in the hospital and 445 (64.3%) patients survived the 30-day period. The median age of the patients was 78 (72-83). Higher National Institutes of Health Stroke Scale (NIHSS) scores (odds ratio [OR]: 2.085; 95% confidence interval [CI]: 1.835-2.370), increased creatinine levels (OR: 2.002; 95% CI: 1.235-3.243), increased platelet levels (OR:1.006; 95% CI: 1.002-1.010), and hyperglycemia (OR: 2.610; 95% CI: 1.023-6.660) were found as independent predictors of inhospital mortality. CONCLUSION: In evaluating geriatric patients with ischemic stroke, laboratory values including platelet count, creatinine levels, hyperglycemia, and NIHSS scores should be considered to predict inhospital mortality in the ED.

Antiepileptic drug poisoning: Three-year experience.

INTRODUCTION: Antiepileptic drugs, which are also called anticonvulsants, are used in the therapy and prophylaxis of epileptic seizures. The purpose of this paper was to investigate the relevant epidemiological data and to determine which of these drugs was the most frequent cause of intoxication. Another purpose of this study was to determine the neurological, cardiac, and biochemical problems caused by antiepileptics. MATERIAL AND METHOD: This retrospective study included 95 consecutive patients under 18 years of age with antiepileptic intoxication, presenting to and being followed-up in, the Toxicology Unit between January 2010 and February 2013. The data were obtained by screening the patient files. RESULTS: Of the cases, 67 (70.5%) were self-poisoned by first generation antiepileptics (FGAEs) and 28 (29.5%) by second generation antiepileptics (SGAEs). The Glasgow Coma Scale (GCS) scores and the serum lactate levels of the patients poisoned by FGAEs and SGAEs on admission to emergency department were 15 (25th: 12; 75th: 15; 95th: 15; IQR: 3) and 1.9 (25th: 1.4; 75th: 3.1; 95th: 5.6; IQR: 1.7), and 15 (25th: 14.3; 75th: 15; 95th: 15; IQR: 0.75) and 1.07 (25th: 0.9; 75th: 1.6; 95th: 5.5; IQR: 0.71), respectively. The serum lactate levels of patients poisoned by FGAEs were significantly higher (p < 0.001). Among the cases poisoned by carbamazepine, the most frequent cause of intoxication, the GCS score was significantly lower and serum lactate level was significantly higher in the group with high serum levels of carbamazepine (p = 0.004 and p < 0.001, respectively). In cases poisoned by valproic acid (VPA), the second frequent cause of intoxication, there was neither a significant association between the serum VPA level and the GCS score, nor between the serum lactate level and the systolic blood pressure (p = 0.470, p = 0.897, and p = 0.088, respectively). However, there was a positive correlation between the serum VPA level and the serum ammonia level (kk = 0.742, p < 0.001). CONCLUSION: First generation antiepileptics are more toxic than SGAEs. In patients with serum carbamazepine level, particularly those over 30 mg/L, serious disorders of consciousness, cardiovascular toxicity, and metabolic disorders may occur. In VPA intoxication, there is a positive correlation between the serum VPA levels and ammonia levels. On account of this finding, one should be more careful about hyperammonemic hepatic encephalopathy as the serum VPA level rises.

Prognostic importance of neutrophil-lymphocyte ratio in critically ill patients: short- and long-term outcomes.

STUDY OBJECTIVE: The number of critically ill patients admitted to the emergency department increases daily. To decrease mortality, interventions and treatments should be conducted in a timely manner. It has been found that the neutrophil-lymphocyte ratio (NLR) is related to mortality in some disease groups, such as acute coronary syndrome and pulmonary emboli. The effect of the NLR on mortality is unknown in critically ill patients who are admitted to the emergency department. Our aim in this study is to evaluate the effect of the NLR on mortality in critically ill patients. METHODS: This study was planned as a prospective, observational cohort study. Patients who were admitted to the emergency department because they were critically ill and required the intensive care unit were included in the study. Demographic characteristics, Acute Physiology and Chronic Health Evaluation II (APACHE II), Sepsis-related Organ Failure Assessment, Glasgow Coma Score, and NLR values were recorded upon emergency department admission. The patients were followed up for sepsis, ventilator-associated pneumonia, multiorgan failure, in-hospital mortality, and 6-month mortality. RESULTS: The median (interquartile range) age of the 373 patients was 74 (190) years, and 54.4% were men. Neutrophil-lymphocyte ratio values were divided into quartiles, as follows: less than 3.48, 3.48 to 6.73, 6.74-13.6, and more than 13.6. There was no difference among these 4 groups regarding demographic characteristics, APACHE II score, Sepsis-related Organ Failure Assessment score, Glasgow Coma Score, and length of hospital stay (P>.05). In the multivariable Cox regression model, in-hospital mortality and 6-month mortality NLR were hazard ratio (HR), 1.63 (1.110-2.415; P=.01) and HR, 1.58 (1.136-2.213; P=.007), respectively, and APACHE II scores were detected as independent indicators. CONCLUSION: The NLR is a simple, cheap, rapidly available, and independent indicator of short- and long-term mortalities. We suggest that the NLR can provide direction to emergency department physicians for interventions, particularly within a few hours after admission, in the critically ill patient group.

Can we use serum gamma-glutamyl transferase levels to predict early mortality in stroke?

OBJECTIVE: Serum gamma-glutamyl transferase (GGT) is a marker for alcohol consumption and hepatobiliary diseases. There are reports on the prognostic role of GGT in coronary artery diseases and stroke. The aim of our study was to identify the potential differences in GGT levels in different types of stroke, and to evaluate the correlation between GGT and 30-day mortality. METHOD: Patients diagnosed with stroke in emergency department between 01.01.2010 and 30.12.2012 was included in the study. Imaging techniques were used to distinguish between hemorrhagic and ischemic stroke. Ischemic strokes were further classified as either atherosclerotic/lacunar or embolic. Parameters including age, gender, vital signs (systolic and diastolic blood pressure), comorbid diseases (HT, DM, CAD, smoking and alcohol consumption), used medications, previous history of stroke, NIHSS score at the time of admission to emergency department, laboratory parameters (glucose, white blood cell count, hemoglobin, platelet, total cholesterol, creatinine) and duration of hospitalization were recorded. Death records were obtained from patients' medical records. RESULTS: One thousand eighty six patients were included in the study. GGT levels were not significantly different between ischemic and hemorrhagic strokes (p=0.435). On the other hand, GGT levels in embolic strokes were significantly higher compared to atherosclerotic/lacunar strokes (p=0.001). GGT levels [median 24.50 (16.00-43.00)] in Intensive Care Unit patients were significantly higher compared to GGT level [22.00 (15.00-34.25)] in admitted to service beds patients (p=0.015). Median GGT level of deceased patients was 24.00 (16.00-41.25) and median GGT level of alive patients was 22.00 (15.00-35.00). GGT level of deceased patients was significantly higher compared to GGT levels of alive patients (p=0.048). CONCLUSION: There was no difference in GGT levels between ischemic and hemorrhagic strokes; however, GGT levels in embolic strokes were significantly higher compared to atherosclerotic/lacunar strokes. High GGT levels are correlated with early mortality in stroke. We believe that GGT may be used as a predictor of mortality in future studies.

Comparison of end-tidal carbon dioxide levels with cardiopulmonary resuscitation success presented to emergency department with cardiopulmonary arrest.

OBJECTIVE: To measure end-tidal carbon dioxide pressure (PetCO2) in preset interval in order to evaluate the efficiency of cardiopulmonary resuscitation (CPR) performed on patients in cardiopulmonary arrest, evaluate the validity of PetCO2 in predicting the mortality and finally assess the PetCO2 levels of the patients in cardiopulmonary arrest based on the initial presenting rhythm. METHODS: This prospective study was conducted at the Ankara Training and Research Hospital on patients who presented with cardiopulmonary arrest. Standard ACLS (Advanced Cardiac Life Support) protocols were performed. Patients were categorized in two groups based on their rhythms as Ventricular Fibrillation and Asystole. Patients' PetCO2 values were recorded. RESULTS: PetCO2 levels of the Return of Spontaneous Circulation (ROSC) group in the 5th, 10th, 15th and 20th minutes were significantly higher compared to the exitus group (p<0.001). In distinguishing ROSC and exitus, PetCO2 measurements within 5-20 minute intervals showed highest performance on the 20th and lowest on the 5th minutes. CONCLUSION: PetCO2 values are higher in the ROSC group. During the CPR, the most reliable time for ROSC estimation according to PetCO2 values is 20th minute. None of the patients who had PetCO2 levels less than 14 mmHg survived.

The experiences in a toxicology unit: a review of 623 cases.

BACKGROUND: To evaluate the etiological and demographic characteristics of adult poisoning patients followed up in a toxicology unit in Konya, Turkey. METHODS: Patients (≥ 15 years old) followed up with the diagnosis of poisoning in our toxicology unit in 2011 were included in this retrospective study. The patients' medical records were investigated. Age, gender, medical history, the first medical center the patient had been admitted to, the routes and causes of poisoning, the toxins involved, the number of the pills taken, treatments, complications, the length of stay in the hospital and the outcome were recorded. RESULTS: A total of 623 patients were included in the study. The mean age of patients was 28.1 ± 15.1. Four hundred and forty-five (71.4%) of patients were female, 541 (86.9%) of them were poisoned via the oral route and 75 (12.0%) of them were poisoned by inhalation. The causes of poisoning were drugs in 408 (65.5%) patients, pesticides/insecticides in 58 (9.3%) patients and carbon monoxide in 49 (7.9%) patients. The commonly used drugs were as follows: analgesics (57.2%), antidepressants (25.4%) and gastrointestinal system drugs (15.8%). The poisonings were suicidal in 489 (78.5%) patients, accidental in 120 (19.3%) patients and overdose in 14 (2.2%) patients. The number of women was higher in the suicide group. At the end of the treatment, 604 (97.0%) of the patients were discharged and 3 (0.4%) of them died. The duration of follow-up was 39.2 ± 37.5 h. CONCLUSION: The most common causes of poisoning are drugs, pesticides/insecticides and carbon monoxide. Health and educational policies at a national level are needed in order to prevent this medicosocial problem. Furthermore, specially equipped toxicology units should be constructed for the treatment and follow-up of the poisoned patients in order to reduce the morbidity and mortality to a significant extent.

Comparison of the effectiveness of intravenous piracetam and intravenous dimenhydrinate in the treatment of acute peripheral vertigo in the emergency department.

INTRODUCTION: We aimed to compare the effectiveness of intravenous piracetam with that of intravenous dimenhydrinate in the treatment of acute peripheral vertigo in the emergency department. METHODS: This double-blind study comprised a total of 200 patients, aged between 18 and 70 years, who had presented to the emergency department of Ankara Training and Research Hospital and were diagnosed with peripheral vertigo. Evaluation of the severity of the patients' vertigo was performed using a visual analogue scale, before and after drug administration. RESULTS: Both drugs were found to be effective (p < 0.001) and had comparable effects (p < 0.474). Dimenhydrinate was also found to have about two times the side effects of piracetam. Drowsiness was found to be the most common side effect of these two drugs. CONCLUSION: Dimenhydrinate and piracetam have similar levels of effectiveness with regard to acute vertigo. We conclude that piracetam, which has fewer side effects than dimenhydrinate, better vestibular compensation, and is effective for both acute and chronic vertigo, could be more frequently used in the emergency treatment of acute vertigo.

A new marker for myocardial injury in carbon monoxide poisoning: T peak-T end.

OBJECTIVES: Carbon monoxide (CO) poisoning frequently affects repolarization, resulting in abnormal electrocardiography findings. The goal of this study was to examine the effect of CO poisoning on the novel transmyocardial repolarization parameters T peak-T end (Tp-e), Tp-e dispersion, and Tp-e/QT and the relationship of these parameters to myocardial injury (MI). METHODS: This prospective study included 94 patients with CO poisoning and 40 healthy controls. Participants received an electrocardiography and had their blood drawn at admission and 6 and 24 hours after admission. The QT, Tp-e, Tp-e dispersion, and the Tp-e/QT ratio were calculated. Myocardial injury was determined based on an elevation in troponin any time during the first 24 hours. The patients were divided into 2 subgroups: those with and without MI. RESULTS: T peak-T end, Tp-e dispersion, and the Tp-e/QT ratio were higher at admission than after 6 and 24 hours of hospitalization and were higher than the control group (P < .001). There was a correlation between the carboxyhemoglobin level at admission and Tp-e and Tp-e dispersion (P < .001). The MI subgroup (n = 14) had a higher Tp-e at admission than did the non-MI subgroup (n = 80) (96 [11] milliseconds vs 87 [12] milliseconds, P = .03). There were no any significant differences in the Tp-e dispersion or the Tp-e/QT ratio between the 2 MI subgroups. Receiver operating characteristic analysis showed that a Tp-e cutoff value for MI of 91.5 milliseconds had a sensitivity of 72.7% and a specificity of 67.2%. CONCLUSION: Transmyocardial repolarization parameters indicative of arrhythmia were prolonged in patients with CO poisoning. T peak-T end was associated with MI.

Hepatic toxocariasis: a rare cause of right upper abdominal pain in the emergency department.

Toxocara canis and Toxocara cati are common helminths that reside in the intestinal tract of cats and dogs. Toxocariasis and, commonly, T. canis, is a disease commonly seen in children, which is characterised by hypereosinophilia, hepatomegaly, fever, transient pulmonary infiltration, and hypergammaglobulinaemia. Humans, who are not the actual host for these parasitic worms, are infected following oral intake of the infective eggs. Radiological differentiation of hepatic toxocariasis can be difficult, as liver lesions, which present as multiple hypoechoic lesions with regular borders, can look like a tumour, an infarction or an infection. We report on a case that presented to our emergency department (ED) with abdominal pain. During the initial review, the pathology in the liver was thought to be an infarction or an infection; however, the patient was diagnosed with hepatic toxocariasis following further evaluation.

[The role of blood S100B and lactate levels in minor head traumas in children and adults and correlation with brain computerized tomography]. / Çocuk ve eriskin minör kafa travmalarinda kan S100B ile laktatin rolü ve bilgisayarli beyin tomografisi ile korelasyonu.

BACKGROUND: In this study, we aimed to set levels of blood S100B and lactate and to determine any correlation with brain computerized tomography in minor head traumas in children and adults. METHODS: This clinical trial is a prospective study including 100 head trauma patients who applied to Ankara Training and Research Hospital emergency service. RESULTS: In this study, cut-off ranges of 0.0-0.15 ug/ml and 0.9-1.7 mmol/L for blood S100B and lactate levels, respectively, were used. S100B level was higher than the cut-off range in 42% of patients and lactate level was higher in 56% of patients. No significant differences were determined between age groups. When the relation between S100B and lactate levels with brain CT was evaluated, no statistically significant relation was determined. CONCLUSION: According to our results, in minor head traumas, the determination of elevated serum S100B and lactate levels cannot take the place of clinical examination and the use of cranial CT. Although the patients in our study group had minor head trauma, we do not consider S100B and lactate to be reliable markers for estimating progression.

Hemodialysis as an alternative treatment of mexiletine intoxication.

Mexiletine is a class IB antiarrhythmic agent. Although it is primarily used in treating ventricular arrhythmias, recent indications for use of mexiletine include chronic and neuropathic pains. At high doses, mexiletine causes drowsiness, confusion, nausea, hypotension, sinus bradycardia, paresthesia, seizures, bundle branch block, atrioventricular heart block, ventricular arrhythmias, asystole, cardiovascular collapse, and coma. A 23-year-old male patient presented to the emergency department with intentional ingestion of high-dose mexiletine. Despite decontamination and supportive treatment, his vitals deteriorated during the observation period; and he developed stupor and dysarthria. Patient then underwent hemodialysis. His vital signs and overall condition improved rapidly following hemodialysis treatment. In this case report, we aimed to emphasize hemodialysis as a useful alternative therapy for severe mexiletine intoxications.

Our new stethoscope in the emergency department: handheld ultrasound.

BACKGROUND: The concept of Focused Assessment with Ultrasound for Trauma (FAST), which was introduced by Rozycki et al. in 1996, has started a new era in the management of trauma patients. Today, Advanced Trauma Life Support (ATLS) suggests bedside ultrasonography (USG) evaluation of trauma patients. We aimed to investigate the usability and the reliability of handheld ultrasound (Vscan) in determining free fluid during the initial evaluation of trauma patients. METHODS: This was a multi-center, prospective study involving multiple trauma patients who presented to three hospital emergency departments (EDs). FAST was completed using Vscan by an emergency physician and an abdominal USG was performed by a radiologist on all patients. Results of Vscan, abdominal USG and other radiological studies, if performed, were compared. RESULTS: A total of 216 patients were included in the study. Of those, 203 had negative Vscan results, while 13 had positive results. When USG performed by a radiologist was considered as the gold standard, Vscan sensitivity for FAST was 88.9%, specificity was 97.6%, negative predictive value was 99.5%, and positive predictive value was 61.5% in our study. CONCLUSION: Vscan, as the smallest portable imaging device, seems to have a promising future as an indispensable gadget, equal to stethoscopes, in evaluating trauma and other critical patients.

Role of C-reactive protein, D-dimer, and fibrinogen levels in the differential diagnosis of central and peripheral vertigo.

Vertigo is encountered frequently in emergency services. Researchers have explored the role of serologic markers in the differentiation of central and peripheral vertigo. The study reported here was designed to evaluate the diagnostic efficacy of serologic markers (fibrinogen, D-dimer, and C-reactive protein [CRP]) in the differential diagnosis of peripheral and central vertigo. A total of 116 patients who sought treatment for vertigo at Gazi University Hospital Adult Emergency Services during a 3-mo period were included in the study. CRP, fibrinogen, and D-dimer levels were assessed in an effort to differentiate between cases of peripheral and central vertigo. In all, 65.5% of patients (76 patients) were women. Patients younger than 50 y of age accounted for 60.3% (70 patients). The average D-dimer level for the entire group of patients was 181.9+/-132.2 microg/mL, the average CRP level, 4.2+/-8.4 mg/L, and the average fibrinogen level, 421.9+/-176.0 mg/dL. Although serum D-dimer, fibrinogen, and CRP values appeared to be higher in patients with central vertigo than in those with peripheral vertigo, no statistically significant differences were noted between the 2 groups in terms of these 3 parameters (P>.05). When 6 mg/L was used as the cutoff point for CRP and 320 mg/dL was used for fibrinogen, the numbers of patients with CRP and fibrinogen levels higher than these values were significantly higher for central vertigo than for peripheral vertigo (P<.05). The present study shows that blood D-dimer, fibrinogen, and CRP levels cannot be significant markers for the differentiation of central and peripheral vertigo.

Metabolic syndrome and its association with ischemic cerebrovascular disease.

Metabolic syndrome (MS) is the term that encompasses metabolic risk factors that may lead to atherosclerotic cardiovascular disease. This study was undertaken to investigate the prevalence of MS in patients with ischemic cerebrovascular disease (CVD), according to National Cholesterol Education Program/Adult Treatment Panel III (ATP III) criteria. A total of 40 patients who were referred to the emergency department and given a diagnosis of CVD were included in this study. Detailed medical histories, physical examination findings, heights, weights, and waist circumferences of patients were recorded. Fasting blood glucose levels and lipid profiles of patients were evaluated. Those with hypertension, diabetes, or hyperlipidemia were regarded as meeting at least 1 of the ATP III criteria. Study results were compared, especially between females and males. In all, 55% of patients were female, and 70% were older than 65 y. Blood pressure over 130/85 mm Hg was assessed in 60% of patients. Among female patients, 81.8% had a waist circumference greater than 88 cm; 50% of male patients had a waist circumference over 102 cm. A fasting blood glucose level above 110 mg/dL was identified in 57.5% of patients. Serum triglyceride levels in 30% of patients were above 150 mg/L. It was noted that 33.3% of male patients had a high-density lipoprotein (HDL) level below 40 mg/L, and in 68.2% of female patients, an HDL level below 50 mg/dL was recorded. According to these findings, 14 of 22 female patients (64%) and 13 of 18 male patients (72%) were identified as having MS. High rates of stroke associated with MS reveal the importance of forthcoming preventive approaches.
