Background : Patients who were discharged from the emergency department(ED) may revisit. These patients are divided into two groups; one is expected scheduled condition, the other is unexpected condition. These patients of inappropriate revisits to the ED would be unsatisfied, difficult to make rapport and take legal action as a result of additional medical charges. The purpose of this study was to reduce inappropriate revisits to the ED with a new method which was developed by analyzing inappropriate revisits in 2002. Methods : This study was conducted in a tertiary hospital consisting of 1,278 beds. The most common cause of inappropriate revisits was the medical team's lack of explanation about a disease. Thus we decided that the effective method was to offer full explanations to patients to understand the clinical pathway of a disease. We made four types of stickers to explain most common 4 diseases in 2003. An emergency physician completed 'discharge explanation report' and explained it to patients in 2004. Results : In 2002 inappropriate revisited patients were 164, patients with four diseases were 79. During the same period of 2003, inappropriate revisited patients were 56 (-65.9%), four disease patients were 6 (-92.4%) and in 2004 inappropriate revisited patients were 52, four disease patients were 19. Causes of revisits were lack of explanation about a disease in 35 patients (44.3%) in 2003, and 5 patients (83.3%) in 2003, and 16 patients (84.2%). Conclusions : Application of 'explanation stickers' at discharge reduced inappropriate revisits from 34.5% in 2002 to 15.9% in 2003. Application of 'Discharge explanation report' by emergency physician reduced inappropriate revisits from 15.9% in 2003 to 13.5% in 2004. Reduction of inappropriate revisits elevated the quality of medical treatment, and decreased patients' dissatisfaction in ED.

Nitrogen is an inert gas that is harmless to humans under normal conditions. While it is not inherently toxic, nitrogen gas becomes dangerous when it displaces oxygen, resulting in suffocation. Herein, we report a case of a 34-year-old man who attempted suicide by nitrogen asphyxiation who presenting with decreased mental function and agitation. Lactic acidosis and hyperammonemia were observed on presentation at the emergency department, but these improved after a few hours. After 2 days, the patient regained full consciousness, and was discharged without any complications. Survival after asphyxiation due to nitrogen gas is very rare, and these patients are more likely to have poorer outcomes. There is a potential for the increasing use of nitrogen gas as a method of committing suicide because of the ease of access to this gas.

Records of 255 patients was analyzed statistically according to the contents of the record form. T patients' records were collected through the visit of emergency department in one hospital by the 119 Emergency Medical Services system from January 1 to February 8, 2009. In conclusion, the total entry was the investigation of 119 ambulance run report in 62.1% of subjects. The highest record of receiving hospital item was 100.0% and the lowest record of medical control item was 0.4% of subjects. Increasing the entry of 119 ambulance run report in efficient emergency medical information delivery media needed to suggest that increasing the number of specialists on the staff, medical staffs have an active interest and feedback, rule to item arrangement of prehospital ambulance run report, continuous education in the importance of record.

Sulfoxaflor is the first insecticide belonging to the sulfoximine class and is efficient against sap-feeding insects that are resistant to other insecticides. Sulfoxaflor acts as a neurotoxin to the central nervous system of insects compared with very low toxicity to mammalian. We report on a case of a 67-year-old male who ingested insecticide and received conservative treatment for mild metabolic acidosis and gastrointestinal symptoms.

Cyanide has been well known from antiquity. Cyanide poisoning causes histotoxic hypoxia--inhibition of mitochondrial cytochrome oxidase with disruption of the ability of cells to use oxygen. The mortality rate is 95% within 30 minutes. Acute cyanide poisoning is mostly the result of attempted suicide, and because of the high doses typically employed it usually is lethal within minutes. Also acute cyanide poisoning leads to a very poor prognosis because medical personnel can't detect cyanide intoxication and so many hospital haven't antidote. We report two cases of cyanide poisoning which responded well to treatment with the Taylor cyanide antidote package.

Splenic rupture is a frequent surgical emergency in blunt abdominal trauma patients. There are several treatment options, including conservative treatment, a partial splenectomy, splenorrhaphy, and a splenectomy for splenic injury. Although reports on the safety and the efficacy of an elective laparoscopic splenectomy are abundant in the literature, a laparoscopic splenectomy for a ruptured spleen has only been reported in a few cases. We report a case of a laparoscopic splenectomy in the patient with Grade III traumatic splenic injury. To our knowledge, this is the first report in which a laparoscopic splenectomy was performed in Korea for the treatment of a traumatic splenic injury.

Potamotrygon motoro, also known as the Marble motoro, is a potamodromous freshwater ray native to the basins of the Amazon River. Marble motoros were introduced to South Korea in the 2000s, and, because they are easy to raise, were sold as aquarium fish. The aim of this report is to illustrate a new case involving envenomation by a Marble motoro. A 35-year-old commercial aquarium assistant came to the hospital after being pricked by a Marble motoro. The clinical picture in this case showed acute local pain with minimal systemic manifestations. This patient recovered after receiving symptomatic treatment and wound care. This case of envenomation accentuates the potential for injury among people coming in contact with a venomous Marble motoro.

Hydrofluoric acid (HF), one of the strongest inorganic acids, is used mainly for industrial purpose. Hydrofluoric acid injuries has a potential for both systemic as well as severe local tissue destruction. One of the most serious consequences of severe exposure to HF by any route is marked lowering of serum calcium (hypocalcemia) and other metabolic changes, such as hypomagnesemia and which may result in a fatal outcome if not recognized and treated. promptly cardiotoxicity is not well known except arrhythmias, which are a primary cause of death. We report a case of myopericarditis by ingestion of hydrofluoric acid.
