Leeches have been in use for centuries, especially in plastic and reconstructive surgery wound and flap healing, in venous insufficiencies, and in the treatment of many disorders such as hemorrhoids and varicosity. With this study, we aimed to discuss coagulation disorder due to uncontrolled leech bites, consequent excessive skin hemorrhage, and anemia requiring blood transfusion. A 65-year-old male patient was referred to the emergency department because of excessive intractable bleeding that had occurred after leech bites. On physical examination, a total of 130 bites were detected on various regions of the body. In the laboratory findings of the patient, hemoglobin and hematocrit levels were extremely low, and prothrombin time, international normalized ratio, and partial thromboplastin time were markedly increased. The patient received a total of 8 units of fresh frozen plasma and 6 units of erythrocyte suspension. Bleeding stopped by decreasing after the transfusion of fresh frozen plasma. Although the complications due to leech injuries are rare, they may be an important cause of morbidity and mortality when an injury or prolonged bleeding in an internal region occurs. Prolonged skin hemorrhages rarely cause anemia, and deaths are caused by intractable hemorrhages. However, a coagulation disorder and consequent intractable hemorrhage have not been reported previously in the literature. In conclusion, it should be known that uncontrolled, blind, and excessive leech use causes severe hemorrhage and excessive blood loss, causing significant morbidity and mortality. Therefore, the awareness of either physicians or people using or recommending alternative medicine should be raised on this subject.

Anticholinesterase poisoning is an important health problem in our country, and a complete understanding of its underlying mechanisms is essential for the emergency physician. Thus, we aimed to investigate the cardiac biochemical parameters and mortality in dichlorvos-induced poisoning in rats. Rats were randomly divided into 5 groups as control (corn oil), dichlorvos, atropine, pralidoxime, and atropine+pralidoxime groups. Immunohistochemical analyses of apoptosis and inducible nitric oxide synthase showed no change in cardiac tissue for all of the groups. Serum cholinesterase levels were suppressed with dichlorvos, and these reductions were inhibited with atropine and/or pralidoxime pretreatment. Serum levels of creatine kinase, creatine kinase-MB, cardiac troponin I, myoglobin, and N-terminal probrain natriuretic peptide were not affected with poisoning. Malondialdehyde and glutathione levels were not statistically significant between the groups. Although serum nitric oxide levels in the dichlorvos group were lower than those in the control group, cardiac nitric oxide levels in the atropine+pralidoxime group were markedly higher than those in the dichlorvos group. Atropine, pralidoxime, and atropine+pralidoxime pretreatments markedly reduced the mortality. In conclusion, our results implied that measured cardiac markers especially N-terminal probrain natriuretic peptide may not contribute to the early (first 6 hours) diagnosis of cardiotoxicity in dichlorvos-induced poisoning in rats. These results also showed that acute dichlorvos administration did not cause significant cardiac damage, and oxidative stress does not play a marked role in dichlorvos-induced poisoning. Besides, cardiac nitric oxide may produce protective effect on myocardium with atropine+pralidoxime therapy in rats.

BACKGROUND Stroke is the most common neurologic cause for patient admission to the emergency department (ED) and the risk of stroke increases with age. This study aimed to determine the clinical and demographical characteristics of stroke-mimicking patients 65 years or older who were admitted to the ED for stroke. METHODS After the retrospective file examination, patients 65 years and older who were admitted to the ED with an established final diagnosis of stroke as a result of history, physical examination, imaging, and required consultations were included in the study. RESULTS After scanning 671 records of patients 65 years or older, 87.3% (n=586) were diagnosed with stroke and 12.7% (n=85) received different diagnoses mimicking stroke. Of these 85 patients, 91.8% (n=78) and 8.2% (n=7) were prediagnosed with ischemic stroke and transient ischemic attack, respectively, by the ED physicians. After complete evaluations and consultations, the patients with stroke were typically diagnosed with vertebrobasilar insufficiency (n=16, 18.8%). Of the patients, 76.5% (n=65) were discharged after treatment and follow-up in the ED, and 21.1% (n=18) were hospitalized. CONCLUSIONS In older patients, stroke-mimicking conditions can cause signs and symptoms indistinguishable from true stroke, representing about 12.7% of elderly patients admitted to an ED with these diagnoses.

Chlorine is one of the most common substances involved in toxic inhalation. Until now, several accidental exposures have been reported. The damage to the respiratory tract in the immediate phase after exposure to chlorine is well defined. Death occurs particularly due to pulmonary edema with respiratory failure and circulatory collapse. On the other hand, no association with myocardial infarction, acute stroke, severe hyperglycemia, and acute chlorine inhalation has been reported in literature. In the present study, an elderly (74-year-old) and diabetic case with myocardial infarction, acute stroke, hyperglycemia, and respiratory failure associated with acute chlorine intoxication after a diagnosis of acute chlorine poisoning and treatment in the emergency department is reported and the literature is revisited. Physicians should know that in elderly patients with a systemic disease who apply with chlorine gas inhalation, more serious complications along with damage in respiratory tract might be observed.

Introduction: Carbon monoxide (CO) intoxication causes cardiovascular problems as a result of diffuse tissue hypoxia. Cardiac biochemical markers and electrocardiographic changes have been reported in CO intoxications. Human fatty acid-binding protein (H-FABP) has been recently used as a reliable marker in identifying early cardiac damage. In this prospective study, we aimed to investigate the advantages of the use of H-FABP, in evaluating the findings of myocardial ischemia in patients with CO intoxication in our region. Methods: Twenty four successive patients admitted to the emergency department with acute CO intoxication were included in our study. Serum traditional markers and H-FABP were also taken in the earliest period for evaluation of cardiac damage. Results: The creatinine kinase MB (CKMB) levels were positive in 11 of the patients; however, H-FABP and troponin T levels were positive in only 3 of them. One of these subjects had elevated level of H-FABP in the short-term and increasing troponin T level increasing level of troponin T during the follow-up period. Conclusion: The obtained data supports the use of H-FABP, a specific indicator in identifying the cardiotoxicity of CO intoxications at an early phase.

BACKGROUND In recent years, thrombolytic therapy has become the main treatment of ischemic stroke. But the increasing use of alteplase in ischemic stroke has made some complications more evident. Angioedema is a rare but potentially life-threatening complication of alteplase treatment. Only a few studies have examined the incidence of angioedema after treatment with alteplase for stroke. METHODS A 75-year-old man complaining of right hemiparesis was admitted to our emergency department. He was diagnosed as having acute ischemic stroke, and alteplase infusion was given two hours after the onset of stroke symptoms. Immediately after the completion of infusion he was noted to have a large swollen tongue. RESULTS His neurological symptoms resolved gradually within 4 hours, whereas his upper extremity strength improved to 4/5 and lower extremity 5/5. Lingual edema resolved within 16 hours without any complication. He died from presumed nosocomial infection 5 days later. CONCLUSIONS Lingual angioedema may appear as a possible complication in patients who were treated with alteplase. The management of these patients should be very careful.

The purpose of this study was to determine the role of red cell distribution width (RDW), neutrophil–lymphocyte ratio (NLR), and platelet–lymphocyte ratio (PLR) in the diagnostic phase of acute pulmonary embolism (PE). We screened 248 consecutive patients who were admitted to the emergency service with PE foremost in the differential diagnosis. Based on spiral computed chest tomography, the patients were divided into two groups. There were 112 confirmed cases of acute PE and 138 patients without PE. Blood samples were obtained within 2 hours of presentation and before starting any medication. There were no significant differences between the PE and the non‐PE groups with respect to sex, age, frequency of disease, serum creatinine, sodium, and potassium (p > 0.05 for all). NLR, RDW, and PLR were higher in patients with PE than those without PE. High‐sensitivity C‐reactive protein, d‐dimer, and troponin levels were also higher in patients with PE. RDW values were positively correlated with troponin levels (r = 0.147, p = 0.021). There were no correlations between RDW and NLR, PLR, or d‐dimer. NLR had a highly positive correlation with PLR (r = 0.488, p < 0.001). In multivariate logistic regression analysis, troponin I, d‐dimer, high‐sensitivity C‐reactive protein, and RDW were found to be independent predictors of PE [odds ratio (95% confidence interval) respectively: 5.208 (2.534–10.704), 1.242 (1.094–1.409), 1.005 (1.000–1.010), 1.175 (1.052–1.312)]. In receiver operating characteristic analysis of the patients in the study, RDW >18.9 predicted acute PE with a sensitivity of 20.7% and a specificity of 93.4%. In conclusion, RDW can be considered useful as a diagnostic measure for patients with suspected acute PE.

Snake bites are leading causes of morbidity and mortality worldwide, especially in rural areas. Therapeutic plasma exchange has been used in the treatment of many different conditions such as immunologic diseases, toxicologic disorders, and snake envenomation. The aim of this study is to evaluate the efficacy of plasma exchange treatment on clinical status, outcomes, and discharge of patients who were bitten by venomous snakes. The study was conducted retrospectively in the Emergency Department of Gaziantep University from January 2002 to December 2011. Thirty-seven patients were included in the present study. Routine biochemical and hematologic laboratory parameters were studied before and after plasma exchange. Demographic data, clinical status, and outcomes of patients were recorded. Plasma exchange was performed by using centrifugation technology via an intravenous antecubital or subclavian vein catheter access. Human albumin/fresh frozen plasma was used as replacement fluids. A significant correlation was seen between therapeutic plasma exchange and improvement of laboratory results. None of the study patients lost their limbs. Eight patients were sent to the intensive care unit. The mean length of the hospital stay was 12.2 days (4-28). All patients were discharged with good recovery. No complications were seen during the 3 months following discharge. Plasma exchange appears to be an effective treatment intervention for snake bite envenomations, especially in the management of hematologic problems and in limb preservation/salvage strategies. In addition to traditional treatment methods, plasma exchange should be considered by emergency physicians in cases of snake bite envenomation as a therapeutic approach to facilitate rapid improvement.

BACKGROUND: Fluid and electrolyte balance is a key concept to understand for maintaining homeostasis, and for a successful treatment of many metabolic disorders. There are various regulating mechanisms for the equilibrium of electrolytes in organisms. Disorders of these mechanisms result in electrolyte imbalances that may be life-threatening clinical conditions. In this study we defined the electrolyte imbalance characteristics of patients admitted to our emergency department. METHODS: This study was conducted in the Emergency Department (ED) of Uludag University Faculty of Medicine, and included 996 patients over 18 years of age. All patients had electrolyte imbalance, with various etiologies other than traumatic origin. Demographic and clinical parameters were collected after obtaining informed consent from the patients. The ethical committee of the university approved this study. RESULTS: The mean age of the patients was 59.28±16.79, and 55% of the patients were male. The common symptoms of the patients were dyspnea (14.7%), fever (13.7%), and systemic deterioration (11.9%); but the most and least frequent electrolyte imbalances were hyponatremia and hypermagnesemia, respectively. Most frequent findings in physical examination were confusion (14%), edema (10%) and rales (9%); and most frequent pathological findings in ECG were tachycardia in 24%, and atrial fibrillation in 7% of the patients. Most frequent comorbidity was malignancy (39%). Most frequent diagnoses in the patients were sepsis (11%), pneumonia (9%), and acute renal failure (7%). CONCLUSIONS: Electrolyte imbalances are of particular importance in the treatment of ED patients. Therefore, ED physicians must be acknowledged of their fluid-electrolyte balance dynamics and general characteristics.

The aim of this study was to determine the profile and appropriateness of the patients’ indications admitted to the emergency department in a state hospital. Adult and pediatric trauma patients admitted to the emergency department of Van State Hospital between March 01 and March 31, 2010, in the course of one month period, were retrospectively analyzed. Data of the 32800 patients admitted to the emergency department during this period were evaluated. Male and female ratio of these patients was 54.8% and 45.2%, respectively, and the most intense group with 77% was the age group of 17-65. The majority of the applications with 60.5% occurred between 8 a.m. and 17 p.m. An examination was asked for 50% of the patients. It was determined that emergency examinations and therapies were applied to 9.9% of the patients, consultation rates were 4.5%, and the highest consultations were taken from orthopedic clinics (16.1%). It was established that 1.4% of the patients were hospitalized, with the highest admission to the general surgery clinic (13.8%). In hospitalized patients, the most common diagnoses were abdominal pain (9.6%), and 88.4% of the patients were discharged from the emergency department. It was observed that the majority of patients admitted to the emergency department need not have been in emergency, and should have applied to primary health care services and policlinics. The results of this study showed that non-emergency patients highly increase the workload of emergency departments, therefore, patients should be trained and awareness of patients should be increased; primary health care services should be made available; accurate, effective and enforceable policies for emergency medical services in the country must be established.
