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.

BACKGROUND: Methemoglobinemia(MetHb) induced by dapsone overdose is not uncommon in Korea, especially in rural area. For treatment of dapsone-induced methemoglobinemia, methylene blue(MB) and activated charcoal(AC) should be used. To date, no reports have compared the amount of MB used between MB alone with MB & AC combined group(MB+AC). And also between moderate (MetHb<35%) and severe (MetHb>35%) intoxicated group defined by initial MetHb level. Authors hypothesized that less amount of MB can be used if MB and AC was used together and larger amount of MB is necessary to reduce MetHb level to asymptomatic level in severely intoxicated group. METHODS: From Jan 1990 to Dec 1996, a total of 54 patients who received treatment for dapsone intoxication were subject of study, The study was done retrospective chart analysis for initial MetHb level, total amount of MB and AC. Wilcoxon rank sum test and Chi-sqiare test was used to compare the total dosage of MB used for each group. Linear regression analysis was used between initial MetHb and the total amount of MB. Results were considered statistically significant when p<0.05. RESULTS: For MB alone and MB+AC group, the differences in total amount of MB used were statistically significant with mean dosage of 7.14+/-1.1mg/kg and 4.28+/-0.7mg/kg, respectively. And total amount of MB used between moderate and severe intoxicated group, the differences were statistically significant with mean dosage of 5.16+/-1.1mg/kg vs. 10.98+/-1.9mg/kg, respectively. There was significant correlation between initial MetHb level (X) and the amount of methylene blue (Y), Y=0.3X-2.42 (r2=0.41, p=0.0001) in MB alone, Y=0.186X-1.95(r2=0.21, p=0.034) in MB+AC respectively. CONCLUSION: For methemoglobinemia induced by dapsone, total amount of MB can be reduced especially in severe Intoxicated group if AC use was combined in treatment modality. There was significant correlationship between initial MetHb level and total amount of MB used.

While the microbiology of cellulitis in the pediatric population and systemic diseases(DM, Cirrhosis, etc) is well known,the causative bacteria and clinical aspect of cellulitis in young adults are less descrihed. this study was undertaken to identify the causative organisms and clinical aspect of adult cellulits. We analysed 121 medical records of 115 young adult patients with cellulitis who had been admitted at the department of orthopaedic surgery, National Police hospital from Jan. 1994. to Dec. 1996. The results were as follows. 1. The age of patient was between 21 yrs and 25 yrs, and the sex of all patients was male. 2. The lower leg and foot were the most frequently involved site of cellulitis as 92 cases(74.2%). 3. The potals were suspected in 65 cases(56.5%),of them, traumas were detected in 43 cases(66.1%), non-traumatic skin lesions in 23 cases(33.9%). 4. In most cases, initial systemic symptoms (fever, chill, headache, etc.) and local symptoms (local heating, tenderness, etc.) were found. 5. The laboratory findings revealed leukocytosis in 19%, elevated ESR in 94%, positive CRP in 80%. 6. Microorganism were detected in 16 of 38 pus cultures. Gram positive microorganisms were detected in 15 of 16 cases culture positive. 7. 6.7% of patients with cellulitis experienced recurrence in same lesions. In conclusion, the retrospective analysis of 115 young adult patients with cellulitis showed that primary cause of young adult cellulit was circulatory disturbance and lymphatic obstruction of the lower extremities most often involved by trauma. therefore, supportive treatments such as rest,elevation,ice packs are considered prior to antibiotic treatment.antibiotic treatment aimed at gram-positive cocci appears to be sufficient.

PURPOSE: To compare the results of posterior cruciate ligament reconstruction by open and arthroscopic method. MATERIALS AND METHODS: From 1995 to 1997, 18 reconstructions of posterior cruciate ligament were performed. Group 1 (open method) was composed of 9 cases and group 2 (arthroscopic method) was consisted of 9 cases. After 21-month follow-up, The two groups were compared by clinical and radiologic methods. RESULTS: Clinically, Lysholm knee score was 80 points in group 1 and 83 points in group 2 after operation. Post operative results by Hughston's criteria were good in 5, fair in 2 and poor in 2 cases (group 1) and good in 6, fair in 2 and poor in 1 cases (group 2). Radiologically, post operative average of posterior drawer stress view was 5.2 mm (group 1) and 5.0 mm (group 2). Almost double the operation time was taken to reconstruct posterior cruciate ligament by arthroscopic method than open method. There were technical errors in 2 cases performed by arthroscopic method. CONCLUSIONS: The results of both methods had no significant difference. We think that the reconstruction of PCL using patellar tendon by open method is a recommendable treatment method together with arthroscopic method, if the merits or demerits of both methods are considered carefully. But more long-term follow-up is necessary to compare the results of PCL reconstruction by open and arthroscopic methods.

Fracture of the scaphoid constitute 60% to 70% of all diagnosed carpal injury. The acute fracture will heal approximately 90% of the time if recognized early and properly immobilized. But nonunion are common since the symtoms do not alert patients to seek early medical treatment and the diagnosis is easily missed. Authors have experienced 19 cases of scaphoid nonunion and accomplished good result in all case by Russe procedure. The results were summerized as follow: 1 The cause of fratures was mainly due to fall down dinjury (36.8%). 2. The most common mechanism of the fracture was fall on the outstretched hand (52.7%). 3. Fractures were shown on the anterior-posterior, lateral and billiards view in all cases. 4. In ten cases, the fractures were found on the waist of scaphoid. 5. The cases of nonunion were probably inadequate intial treatment and delayed diagnosis. 6. The good results were obtained by bone graft according to Russe procedure.

The herniation of intervertebral disc is possibly diagnosed through the myelography, electromyography, discography or computerized tomography. Among them, the myelography is regarded as the popularized method that helps accurate analysis on the location and pattern of the lesion. The authors have studied 363 cases of herniated intervertebral disc with respect to the diagnostic accuracy of myelographic examination from January, 1982 to December, 1985 at the Department of Orthopedic Surgery and Radiology, National Police Hospital. The results were as follows; 1. The most common age group was 21 to 30 years old and ratio of male and female was 9.7: l. 2. The most common site of the lesion was between L4 and L5 vertebra in myelography. 3. Of the 363 cases which underwent the myelography, 305(84.0%) represented positive findings. 4. Myelographic accuracy was coincided with the clinical diagnosis regarding the location of herniation of intervertebebral disc in 262 cases(72.1%).

Entrapment neuropathy of the suprascapular nerve is rare and frequently overlooked in the differential diagnosis of shoulder pain. There have been few published reports on a ganglion compressing the suprascapular nerve. We experienced a case of entrapment neuropathy of the suprascapular nerve by a ganglion that compressed the inferior branch of suprascapular nerve at the spinoglenoid notch.

Twelve eyeys of retinal detachment with full thickness macular hole without(Group 1:6 eyes) and with(Group II:6 eyes) peripheral retinal tears were treated by pars plana vitrectomy and partial or full fluid gas exchange at our hospital from 1987 to 1990. Five showed high myopia, four had trauma histories and in the remammg three were of unknown cause. Other procedures included were; internal drainage of subretinal fluid through macular hole(6 eyes), transscleral drainage(one eye), membrane peeling(one eye), encirclement(7 eyes) and segmental buckle(6 eyes) for peripheral retinal tears and silicone oil injection(one eye). No direct attempts to seal macular hole using photocoagulation or posterior pole buckles were made. During the follow-up period ranging from 6 to 25 months, retinal reattachments were achieved in eleven eyes(92%) and visual acuities improved in seven eyes(58%), were unchanged in three(25%), worsened in two(17%). The causes of worse vision included a redetachment and a macular slantng by high buckle for the tears elsewhere posterior to equator. Among several causative factors, a method releaving the vitreal traction component and a temporary internal tamponade with gas is thought to be the best way to treat this disease.

Histopathologic studies for Helicobacter pylori (H. pylori)-associated chronic gastritis have been mostly undertaken with endoscopic biopsy specimens, often leading to an inappropriate evaluation of the gastric mucosal alterations. The purpose of this paper was designed to investigate the actual prevalence of lymphoid follicle formation by H. pylori infection using the resected stomachs. A total of 16 fresh gastrectomy specimens bearing gastric carcinoma were examined under the quick and gentle procedure, with which H. pylori was detected in 12 cases (75%) and lymphoid follicles in 14 cases (87.5%), while the detection rate of H. pylori remained 56.3% in the control group which comprised the same 16 resected stomachs and were examined by routine tissue preparation procedure without any special care. There was a significant correlation between the presence of H. pylori and lymphoid follicle formation (p=0.05), but no correlation was found between the grades of H. pylori and lymphoid follicles. The topographical distribution of H. pylori or lymphoid follicles in antrum and body gave no statistical difference. Similarly, there was no correlation between H. pylori infection and intestinal metaplasia, activity of chronic gastritis or histologic types of accompanying adenocarcinoma. We conclude that studies of the gastric mucosal change by H. pylori infection using the gastrectomy specimens provide a useful information for analysis of lymphoid follicle formation which is a consistent morphological characteristic of H. pylori infection.

Cytomegalovirus (CMV) infection is an uncommon association with idiopathic inflammatory bowel disease (IBD) often leading to a variety of serious complications. A total of 41 resected cases of IBD were examined to elucidate the pathologic features of intestinal CMV infection which was assessed by histologic examination and confirmed by immunohistochemistry with CMV antibody. Six cases were positve for CMV antibody; five cases in 19 ulcerative colitis (UC, 26.3%) and one case in 22 Crohn's disease (CD, 4.5%). Of 7 cases of the steroid-treated UC group, five cases were superinfected with CMV (71.4%) but none in 12 cases of the steroid-untreated UC group. All of the five CMV-positive cases in UC showed deep ulceration and transmural inflammation, while none of 10 UC cases without above features were CMV positive. Fibrinoid necrosis and thrombi were found in 83.3% of the CMV infected group, while none in the CMV-negative group of UC cases (p=0.01). We conclude that IBD, particularly UC, is susceptible to the CMV infection when steroid hormone is administered, and that deep colonic ulceration, transmural inflammation and fibrinoid necrosis of vasculature may suggest superinfection of CMV in UC patients. It seems that deep colonic ulceration may be the consequence of an ischemic change following vascular luminal occlusion or vasculitis by CMV infection.
