Most orthopedic surgeons were aimed at the rigid internal fixation on the surgical treatment of the fracture. And the compression plate was developed and regarded as an excellent rigid internal fixation device by its advantages of accurate anatomical reduction, early joint mobilization and shortening of the duration of the fracture healing, which are chief aim of A.S.I.F. method. During the period of January 1970 to December 1979, 67 cases of diaphyseal fractures of the long bones were treated with compression plate according to A.S.I.F. method at the Department of Orthopedic Surgery, College of Medicine, Seoul National University and results were obtained as follows: 1. The age of patient was ranged from 15 to 77, and the highest incidence was in the 3rd decade male group (31.4%). 2. Old fracture cases were slightly more than fresh cases, and the fresh femur fracture was the commonest. 3. The periods of the postop immobilization of fresh fractures were 3.7 weeks in humerun fracture, 6.3 weeks in forearm fractures, 8.7 weeks in femur fracture and 7.0 week in tibia fracture, and in old fractures about 4 weeks was longer than fresh fractures. 4. The bony union was accomplished in all cases between 8 week and 24 week. 5. The complication were 4 superficial infections, 4 deep infections, 1 delayed union and 9 joint stiffnesses. 6. Compression plate fixation is considered as an excellent method for the treatment of the fractures of the long bones.

It is widely blieved that the new bone formation is provoked by fine electrical stress to bone. There have been maay experimental studies that showed much efforts to define these small amounts of electricity, and these fine electricities are being used in the orthopedic field for the treatment of various fractures, nonunions and pseudsrthrosia The auther has checked the electrical potentials changing in the course of fractvre hesling in rabbits femur. Comparing these data with that of the normal control group, the following results were obtained. 1. In the normal rabbit's femur the electrical potentisl was 13.6mV less on the concave side than on the convex side. This finding can be explained by the existence of stress generated potential or piexoelectricity. 2. Electrcal potentials on the fractured femoral sites were lowered significantly from that of the control group. So auther could confirm the existence of bioelectrical generated by increased electrical activity of the living bone. 3. The electrical potential of the fractured femoral site has been decreased 50% and 20% as low as that of the normal site at 8 weeks respectively. It is expected that these lowered electrical potentials may become dose to the normal values when the changed metabolic process due to the fractured bone is no longer functioning and it is believed to take human 2 years to get the normal value.

CT findings of twenty-four patients with adrenal gland tumors were analyzed to evaluate their location, size,shape, density etc. The post-surgical confirmation was made in 17 cases. The findings were as follows: 1. 4-10cmsized tumor messes were most common (42%). 2. Round or oval shaped forme were most common (59%). 3. Functionaltomors were 71% (17/24) including Cushing's syndrome of 10 cases, pheochromocytomas of 6 cases and aldosteronismof 1 case. 4. Abnormal adrenal glands were delineated in 88%(21/24), most effectively by CT. We concluded that CTwas the valuable study in the evaluation of the adrenal gland tumors and in the determination of surgicaloperation.

There are various complex formations between immunoglobulin and serum enzymes in the body. Of these, LD-Immunoglobulin complex is most common. It has reported that LD-IgG or LD-IgA complex existed in the serum of healthy person or many patients who have various clinical disorders. The clinical significance of complexes is not known, but it results in the increase of total LD activity and interference to the LD isoenzyme electrophoresis interpretation due to its anomalous pattern. We have reported a case of LD-Immunoglobulin complex in AILD(Angioimmunoblastic lymphadenopathy with dysproteinemia) with reference. The patient was admitted with fever, chills and cervical LN enlargement, in LN biopsy, diagnosed AILD, and during treatment expired by sepsis. Since admission, serum total LD activities were increased and serum LD isoenzyme EP showed that LD3-5 fractions was not separated in broad single band. Its pattern was due to LD-immunoglobulin complex, LD-bound immunoglobulin was IgG ,lamda. For the identification of immunoglobulin, we at first did serum protein immunoelectrophoresis. then stained the plate with tetrazolium dye for LD activity.

BACKGROUND: It has been documented that certain prognostic factors may affect the outcomes of the old aged victims by trauma. Considering that trauma is the sixth most common cause of death in people over the age of 65 years and there is a rapid growth of elderly population, it is paramount to understand the prognostic factors when dealing with geriatric trauma patients. Hypothesis and Goals : It can be hypothesized that the prognostic factors should be determined independently between populations being consisted of different races, countries, socio-economic states, cultures, or so on. Thus, study was designed to evaluate the factors affecting the outcomes of elderly Korean trauma patients. METHODS: One hundred forty six patients aged over 65 years were retrospectively reviewed, who visited the Emergency Canter of Korea University from January, 1997 to June, 1998. Of 146 patients, 7 were excluded due to discharge against advice or transfer to the other hospitals. Parameters analysed were age, sex, mechanism of injuries, body region injured, Injury Severity Score (ISS), previous medical illness, hospital morbidity, duration of hospital stay, and cost. Each patient was classified into improved or not-improved groups depending on the outcomes, and young-old or old-old group depending on the age. The factors affecting the hospital stay in improved patients were analyzed in the parameters of previous medical illness, hospital morbidity, multiple injuries, ISS, and age. All statistical tests were conducted with two-tailed levels of 0.05. RESULTS: Of 139 patients, the mean age was 74+/-7.1 years, mean ISS 9.3+/-7.26, mean hospital stay 27+/-27.1 days. Most commonly injured body region was the extremities due to fall from a level surface. Rate of previous illness showed 0.94 medical diseases per person and were aggravated after trauma in 39 patients (60.9%). Hospital morbidity rate was 0.46 incidents per person. There were no differences in age and duration of hospital stay between the improved and the not-improved group. Substantial differences were noted in affected body region, incidence of previous illness, and hospital morbidity between the groups (p=NS). Not-improved group had higher ISS (p<0.05). ISS, previous illness and hospital morbidity affected the duration of hospital stay in the improved group. Hospital stay was 40+/-25.1 days in patients with ISS over 6 while 6+/-8.6 days in those with ISS 5 (p<0.05). Hospital stay in the improved was 26+/-26.9 days while 31+/- 24.8 days in the improved old-old group (P=NS). Hospital stay in the young-old minor trauma (ISS5) patients with previous illness and hospital morbidity was 26+/-10.1 days while 4+/-7.3 days in those without previous illness and hospital morbidity (p<0.05). CONCLUSION: Previous medical illness and hospital morbidity, not age, are predictive of outcomes of geriatric trauma patients with respect to hospital stay. As most of the hospital morbidity was a trauma-induced aggravation of previous medical illness and hospital morbidity contributing poor outcomes can be potentially avoidable, routine aggressive care far the geriatric trauma patients with previous medical illnesses is needed.

Nevus lipomatosus cutaneous superficialis is a very rare skin disease which usually is present from birth. This uncommon condition is due to collections of ectopic. fat cells within the upper and mid dermis. There are two clinical varieties. The first is a lesion of zonal distribution, present from birth or childhood, usualIy on the buttocks or the lower back. The second form, a dome or sessile, papule, begins. in adult life and is less restricted in distribution. Cerebriform plaques tend to form from the coalescence of soft, yellowish papules. The authors observed two cases of typical nevus lipomatosus cutaneous superficialis. The first case is a 25-year-old female who has had asymptomatic, soft, skin colored, and huge confluent nodules on the right infragluteal fold and upper thigh for 15 years; and the second case is a 15-year-old male who has had multiple, skin colored and soft papules or nodules in zosteriform distribution affecting the right side of the lower back and coccygeal area and right buttock for 4 years. The authors made the diagnosis of nevus lipomatosus cutaneous superficialis from the characteristic clinical and histopathological findings.

STUDY OBJECT: To date, the study of critical illness in the emergency department has been limited. The purpose of this study was to determine the length of stay and procedures performed on critical care patient in ED, and to be help to establish Emergency physicians' education program. METHOD: We reviewed patient's medical record, who visited ED, Korea Univ. Hospital from Jan. 1996 to Jun. 1996 and admitted to ICU. We analyzed data to age, sex, clinical diagnosis, length of stay, and critical procedures in ED. RESULTS: The 12,721 patients visited ED during the study period, the 441 of 12,721 (3.50%) patients admitted to ICU. 56 patients were excluded whose medical re cords were incomplete. The study populations consisted of 165 women and 220 men. The mean age were 52 year old (median,58 year old). The mean length of stays were 606.1 (1445.9 minutes (median, 180 minutes)). One hundred sixty one of these patients (41.8 %) received one or more critical procedures. The medical critical patients were 252 cases, and surgical critical patients were 133 cases. The mean length of stay of medical critical patients was 738.8 (1748.9 minutes (median, 177.5 minutes)) in medical department,44.0% of them received critical procedures in ED. The surgical critical patients averaged 354.9 (410.7 minutes (median, 190 minutes)) and 37.6% received critical procedures. CONCLUSION: Critical ill patients stay in the ED with a substantial amount of time, before addition to the ICU. Critical ill patients who have hemodynamiccal unstable conditions, compromised cardiopulmonary functions, and neurologic deficities, were managed in ED frequently. Typical critical care procedures are commonly performed by emergency physicians. Therefore, it is important for emergency physician to prepare to critical ill patients.

BACKGROUND: The potential adverse effects of ketamine in neurosurgical anesthesia have been well established. However, the effects of ketamine on intracranial pressure (ICP) and hemodynamics during general anesthesia remain unclear. The purpose of this study was to assess the effects of ketamine on hemodynamics and ICP in anesthetized, ventilated rabbits. METHODS: Thirty rabbits were divided into three groups: Group 1 (n=10) received 1 ml/kg normal saline iv; Group 2 (n=10) received 0.5 mg/kg ketamine iv; Group 3 (n=10) received 1.0 mg/kg ketamine iv. After induction with thiopental, anesthesia was maintained with isoflurane and nitrous oxide in oxygen. During controlled ventilation, ICP, mean arterial pressure (MAP), cerebral perfusion pressure (CPP) and heart rate (HR) were measured. The ICP was measured using Ladd ICP monitoring system. All variables were evaluated at baseline and for 30 min following ketamine. RESULTS: In group 1, ICP, MAP, CPP and HR were unchanged over the course of the study. In group 2, ICP, MAP and CPP were unchanged. HR increased at 1, 3 and 5 min (p<0.01), 10 and 20 min (p<0.05) after injection. In group 3, ICP, MAP and CPP increased at 1 and 3 min (p<0.01) after injection. HR increased at 1, 3 and 10 min (p<0.01), 5 min (p<0.05) after injection. CONCLUSIONS: These results suggest that 0.5 and 1.0 mg/kg of ketamine don't significantly affect the hemodynamics and ICP in anesthetized, mechanically ventilated rabbits.

In order to investigate the occurrence characteristics of cancer in terms of industry in Kwangju-Chonnam area, medical utilization records of industrial medical insurance corporations during the period of 1987 to 1988 were reviewed for the identification of neoplastic disease. The cases obtained from the medical records were followed up for the verification and to get additional information. Standardized incidence data were compared by occupational characteristics. Multiple logistic regression analysis was applied to analyze the difference of incidence or distribution of cancer as a whole or of some selected cancer. Total cases of cancer identified were 242 during the study period. Annual incidence rate was calculated as 123.1 per 100,000 person. The frequent types of cancer were cancers of stomach, liver, lung, colon and rectum, bladder and lymphoma in descending order. Employees of mine and other sand handling industries showed significantly higher risks for cancer of stomach and cancer as a whole. Employees of the transportation industry showed the higher risk for cancer of liver. Workers in small-sized industry (< or = 100) had a higher risk for cancer than who in large-sized industry (>100). These findings suggested the effect of occupational environmental exposure to cancer development.
