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.

It is difficult to predict the recurrence of or the prognosis for breast cancer because of its tortuous postoperative course. There are many clinical factors and serologic markers which might be associated with the recurrence of the breast cancer, their relationship to recurrence has not been settled. For this reason, carried out a clinical study to determine the risk of recurrence according to the clinical factors, to evaluate the survival rate after recurrence, and to determine the usefulness of several serologic markers which might be associated with recurrence. To that end, medical records of 365 out of 415 patients (except stage IV patient and patients of underknown whereabouts) with breast cancer who underwent surgical therapy between January 1986 and June 1996 at the Department of General Surgery, Hanyang University Hospital, were retrospectively reviewed. By the time of follow up, recurrence had occurred in 58 of those 365 patients. The DNA ploidy pattern, the primary tumor size, and primary lymph-node metastasis were associated with recurrence. The last two were high risk factors for recurrence of breast cancer. The most common site of recurrence was the locoregional area, followed by the visceral organs and bones. There was a significant differece in survival according to the location of recurrence. The poorest prognosis was obtained for patients with multiple metastases, followed by visceral and bone metastases. Patients with a locoregional metastasis has a better prognosis than others. The serologic markers that significantly increased at recurrence were CEA, ESR, alkaline phosphatase and r-glutamyl transferase. They should be useful serologic markers for diagnosing the recurrence of breast cancer. However, CA15-3 failed to show any statistical difference because of its low concentration. Therefore, better statistical data are required for CA15-3.

Cortical Blindness is loss of vision due to injury of geniculocalcarine visual tract, usually caused by cerebrovascular disease. Cardiac arrest leads to global brain hypoxia or to more focal neurologic deficits. Cortical blindness is one form of these focal neurologic deficits. The severity of visual disturbance in cortical blindness is variable, so the diagnosis can be made later unless emergency physicians are familiar with it. We report a case of transient cortical blindness following hypoxic episode caused by coronary vasospasm.

Pheochromocytomas are rare tumors that originate in chromaffin tissue and produce distant variant effects, such as EKG abnormality, myocarditis, cardiomyopathy, and acute coronary syndrome, by secretion of catecholamines. Such variant effects of pheochromocytoma tend to lead the emergency physician to a wrong diagnosis. We describe the case of a 29-year-old female with pheochromocytoma who was diagnosed at the ER as having myocarditis with acute renal failure. The diagnosis of pheochromocytoma was made later. To avoid misdiagnosis, we should include pheochromocytoma in the differential diagnosis. We should also use additional imaging tests, such as bed-side abdominal ultrasonography or abdominal CT, at the ER on relatively young patients presenting with hypertensive crisis, acute renal failure, and features, such as ischemic EKG changes, which are suggestive of acute coronary syndrome or myocarditis.
