Journal of the Korean Society of Emergency Medicine 1997;8(2):150-154
BACKGROUND: To determine whether N-acetylcysteine(NAC) reduces methemoglobin. METHOD: We carried out an in vivo experiment in rats, weighed about 300g. Each rat was ingested 200mg of dapsone(4,4'diaminodiphenyl sulphone) to induce methemo- globinemia. After 1 hour, 30 rats were received NAC 160mg(2ml) and another 30 rats, served as control, were received 2ml of normal saline orally,4 times hourly. Serum methemoglobin concentrations were checked 1,6, and 24 hours after dapsone ingestion. RESULT: The methemoglobin concentrations on each time were 27.1+/-5.8%,23.5+/-8.8%, 17.1+/-6.4%(mean+/-SD) in control group and 25.5+/-6.3%, 25.5+/-8.8%, 65.5+/-31.2%(mean+/-SD) in NAC group. There were no differences on methemoglobin concentrations at 1 and 6 hours between two groups(P>.05). At 24 hours, the methemoglobin concentrations of NAC group was significantly higher than those of control group(P<.01). CONCLUSION: NAC had no therapeutic effects on dapsone induced methemoglobinemia in this experimental setting.

BACKGROUND: Maritime medicine refers to the medical care and education of medical disease which may develop during a cruise. Recently, cruise passengers are increasing around the world and maritime medicine has been initiated in Korea with beginning of the trip to Mt. Kumgang in 1998. Nowadays, there are about 4,000 passengers per week. Therefore, the data were analyzed to promote the understanding of maritime medicine, which was first applied on the Mt. Kumgang cruise, and to help the medical members who will be participation in the maritime medicine in the future. METHODS: From November 1998 to February 1999, all patients who visited to medical cabin of the cruise ship(Hyundai Pongnae) were analyzed retrospectively. RESULT: 2,162 patients excluding 182 patients who re-admitted were analyzed. In each cruise, there were 65.5(9.0%) passengers and 42(13.0%) crews. The male to female ratio was 1.6 : 1, with 709 males and 451 females. The common problems were respiratory and musculoskeletal diseases followed by dematologic and gastrointestinal problems in order of frequency. There were 18 patients who had trauma above 4 points in ISS. Ten patients were confined to the medical cabin. The ship returned to Donghae-port one time, 8 patients were evaluated immediately and 41 patients were referred without urgency. CONCLUSION: Maritime medicine has a particular characteristic of dealing with various cases and treatments including emergencies with limited space, man-power, facilities and equipment. It obviously proposes the participation emergency medical doctors in the maritime medicine because medical personnel must take part in not only medical management but also in education and prevention including CPR. The medical staff in charge of maritime medicine should establish a proper plan depending on the purpose of the cruise and must endeavor to solve the problem.

Nineteen patients with twenty six fingers were admitted to the Department of Orthopedic Surgery, Yonsei University College of Medicine with Zone II flexor tendon injury of the fingers during a period of 9 years from January 1980 to December 1988. 17 cases received free tendon graft and 9 cases received staged tendon graft. The result of long term follow-up of these patients are as follows. 1. The interval from tendon injury to tendon graft did not influence the operational result. 2. The main factor influencing operational result was flexion deformity whieh was in turn deeply related to preoperational passive range of motion. 3. Due to the relative anatomic simplicity, the thumb had better results after treatment than the other fingers. 4. Satisfactory results were obtained with free tendon graft in most of the Pre-operational Grade I group, good soft tissue without scarring or joint contracture, whereas in the Grade II group and above, complicated with scarring, joint damage or nerve injury, free tendon graft resulted only in 33 % success. 5. In Grade II group and above, free tendon graft resulted only in 33% success whereas 71% of staged tendon graft resulted in good or excellent results. This suggested that staged tendon graft had better operational results than free tendon graft in cases of severe tendon injury.

BACKGROUND: Intermediate myasthenia syndrome(IMS) is thought to have clinical importance because it may cause sudden respiratory failure during the recovery phase of a cholinergic crisis of organophosphate poisoning. We designed this study to identify the prevalence, the inducing agent, clinical predictor, and the proposed treatment of IMS. METHODS: Patients who had admitted with the diagnosis of acute organophosphate poisoning from 1992 to 1998 at two teaching hospitals were enrolled in this study. We selected the cases of IMS based on a review of medical records using modified He's criteria. RESULTS: Twelve(12) out of 110 patients with acute organophosphate poisoning were diagnosed for a prevalence at 10.9%. The drug inducing IMS were identified as dichlorvos, fenthion, EPN, methidathion, and phosphamidon. The occurrence of IMS was not related to either the initial treatment with atropine and pralidoxime, or the level of serum cholinesterase. Complications were pneumonia, sepsis, pancreatitis, and pseudomembranous colitis, etc. Eleven(11) patients were discharged without sequelae, and one patient was discharged as a hopeless care. CONCLUSION: This study suggests that IMS is not rare, so close observation is required to detect IMS in organophosphate-poisoning patients. Also, more studies are required to find predictors and treatments.

BACKGROUND: This study was designed to describe the current tends of emergency tracheal intubation and predict difficult airway intubations in emergency department (ED) at a teaching hospital in Korea. METHODS: All patients who was taken endotracheal incubation in ED during a 1-year period (Mar 1997 through Feb 1998) were included in the study population. Medical records of the patients were retrospectively reviewed. Among them, 56 patients were prospectively evaluated parameters to predict difficult airway intubations. RESULTS: During the study period, a total of 413 patients(1.5%) required endotracheal intubation. Except far 2 cases, all patients intubated orotracheally, and 298(72%) patients were intubated by emergency medicine resident. Pharmacologic adjuncts were used in 200(48%) patients, the neuromuscular blocking agent(NMBA) was used in 16(3.8%) Commonly used drugs were thiopental and vecuronium. The difficult incubation was not associated with presence of denture, length and circumference of neck, and mental status. The visibility of vocal cord on laryngoscopy significantly correlated to the difficult airway. CONCLUSION: At this institution, the majority of ED incubation were performed by emergency physicians and NMBA was not routinely used. The visibility of vocal cord during the direct laryngoscopy could be a predictor of difficult incubation in ED.
