ABSTRACT
OBJECTIVE: To investigate electrocardiogram changes due to scorpion stings and association between oxidative stress index, body oxidant/antioxidant system and the electrocardiogram changes. METHODS: The study was conducted at the Faculty of Medicine, Gaziantep University, Turkey, between May 2009 and October 2010. It comprised 44 patients admitted to the emergency department for scorpion sting, and a control group of matched age and gender of 20 persons. Electrocardiograms were taken promptly in the most painful phases of the patients. Cardiac parametres were measured. Erythrocyte packages were prepared to detect toxin/antioxidant levels. SPSS 18 was used for statistical analysis. RESULTS: Of the 44 patients, 22 (50%) were male. Overall average age of the patients was 45.22 +/- 17.99 years. None of the patients required intensive care and none of them had limb losses. Cardiac parametres of the patients in electrocardiogram were higher (p < 0.05). Difference between those with changed electrocardiogram and unchanged electrocardiogram in terms of the values of total antioxidant status, total oxidant status, and oxidative stress index, were not statistically significant (p > 0.05). CONCLUSION: Scorpion stings associated with electrocardiogram changes. The mechanism of this relationship is not related with the status of body oxidative stress index and body oxidant and antioxidant capacity. Some parametres warrant further study in terms of potential serious arrhythmias in scorpionism.

OBJECTIVE: The aim of this study is to investigate the antioxidant status (TAS), oxidant status (TOS) and oxidative stress index (OSI) in patients with snake envenomation and to learn more about the pathophysiology of snake envenomation. METHOD: Between May 2009 and October 2010, 47 patients were admitted to our emergency department with snake bites, and as a control group 20 healthy volunteers were enrolled in this study. Serum, plasma, and erythrocyte components were prepared for all patients on admission and at the control after 1 month. Serum TOS/TAS levels were measured. RESULTS: No correlation was observed among age, gender and the levels of TAS, TOS and OSI. TAS, TOS and OSI levels were higher in snake envenomation patients upon arrival at the emergency department than in the healthy control group. Upon admission, all levels of patients with snake envenomation were higher than the control levels taken after 1 month. CONCLUSIONS: Serum TAS, TOS and OSI levels increase in snake envenomation patients. The results obtained in this study indicate that the snake bite was associated with a shift to an oxidative state, and oxidative stress plays an important role in the pathophysiology of snake envenomation.

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: Snake bites are an important cause of mortality and morbidity worldwide, especially in rural areas. OBJECTIVE: The aim of this study was to investigate serum paraoxonase (PON), arylesterase (ARLY), ceruloplasmin (Cp), and myeloperoxidase (MPO) activity and lipid hydroperoxide (LOOH) and total sulfhydryl group (-SH) levels in patients with snake venom poisoning. METHODS: The study included 49 patients with snake bite envenomation (Group 1) and 39 healthy volunteers as the control group (Group 2). Plasma PON, ARLY, Cp, and MPO activity and LOOH and -SH levels were measured. Laboratory measurements of 20 patients with snake bite envenomation (Group 3) were performed again after treatment. RESULTS: PON and ARLY activity and -SH levels were significantly decreased in Group 1 compared with those in Group 2. Cp and MPO activity and LOOH levels were significantly elevated in Group 1 compared with those in Group 2. PON and ARLY activity were significantly elevated in Group 3 compared with those in Group 1. Cp and MPO activity and LOOH levels were significantly decreased in Group 3 compared with those in Group 1. CONCLUSIONS: Patients with snake bite envenomation had increased oxidants (MPO and LOOH) and decreased antioxidants (PON, ARLY, and -SH). Results obtained in this study demonstrate that snake bites are associated with a shift to oxidative status. Therapy with antioxidants can lead to an increase in the antioxidant defense system, and thus improvements in clinical symptoms.

Medicinal leeches have been used in the treatment of many diseases for thousands of years. A 25-year-old man presented to our emergency department with bleeding from right and left side of his neck. He had applied leeches 10 h previously to both sides of his neck to treat acne. The bleeding was not controlled by applying pressure with sterile gauze upon the wounds. Homeostasis was achieved by primary suture under local anaesthesia. Prolonged bleeding can be seen following medical leech application. In such cases, bleeding can be controlled by primary suture.

Hydrogen peroxide (H(2)O(2)) is a colourless and odourless liquid with oxidant characteristics used for various purposes. Whereas in lower concentrations (3%), H(2)O(2) is used as a disinfectant in home cleaning products and wound care, in higher concentrations (35%) it is used in textile and paper industry as a bleaching agent and is diluted for use in lightening hair dyes. Like other caustic substances, direct injuries may develop if H(2)O(2) is swallowed and systemic air embolisms may occur due to the resultant gaseous oxygen. This study discusses a patient who was detected with the presence of gas in the portal venous system due to H(2)O(2) intoxication and was treated conservatively.

Carbon monoxide (CO) is a colorless, odorless, nonirritating, toxic gas produced by the incomplete oxidation of hydrocarbons. Common sources of CO include motor vehicles, house fires, furnaces/heaters, and wood-burning stoves. It is a serious health problem resulting in approximately 50,000 visits to the emergency department and is responsible for 3500 deaths annually in the United States. Besides accidental exposure, CO is also one of the leading causes of death by suicide. In the present study, we discuss compartment syndrome caused by CO poisoning in a 15-year-old boy. To our knowledge, this is the first CO poisoning case causing compartment syndrome.

We present a case of non-fatal poisoning with oleander blooms in a 42-year-old woman. After repeated vomiting and gastrointestinal distress, the patient was admitted to the hospital with cardiac symptoms 4 h after the ingestion. Urine and blood samples were assayed for drugs of abuse and for general toxicological screen. Blood was analysed for alcohol and volatiles. Oleandrin was detected in the blood sample at a concentration of 14.7 ng/ml. Following a review of the literature, this is the first case of oleander poisoning in which the patient recovered with only conservative treatment. Oleander poisonings occur rarely, and generally result in death.
