Due to its anatomical position and histological characteristics of thin capsule and low abundance of connective tissue, the spleen is a prime target for damage from blunt injury or during operation. Until recently, total splenectomy has been considered as safe operation for splenic injuries. But now, splenic salvage procedure or non operative treatment have become the standard care with knowledge for immunologic function of spleen, development of radiologic examination such as ultrasonography and abdominal CT, and report about high risk of mortality after splenectomy. Authors have experienced 27 patients with splenic injury admitted to the emergency department during 5 years 4 months period from 1991 to 1996. Among them, 10 patients were received total splenectomy, 2 patients partial splenectomy, 8 patients splenorrhaphy, one patients hemostasis, and 6 patients underwent nonoperative management.

We studied the natural history of asymptomatic early avascular necrosis of the femoral head in forty-three patients(forty-three hips) who had been treated with arthroplasty due to progressed avascular necrosis of femoral head but had no symptoms in the other side. All initial lesions were classified with Ficat staging and International classification(ARCO). The duration until symptom onset and radiologic evidence of disease progression were evaluated. The average follow up period was over 37 months. Among forty-three hips, twenty-nine cases(67.4%) remained asymptomatic until last follow up but fourteen cases(32.6%) were symptomatic during the follow up, and twenty-six cases(60.5%) did not progress on the radiography but seventeen cases(39.5%) progressed to Ficat stage 3 or 4. Fifteen cases of IA, IIA, IB-cental and II B-central without lateral lesion did not occur symptom and didnt progress to Ficat stage 3 or 4 over a period of average 47 months(24-71 months). But fourteen cases of IB, IC, g B and II C progressed to Ficat stage 3 or 4 and they were all lateral lesion. These results suggest careful observation only can be done in the case of small involvement(less than 15%) and medial or central lesion relatively over a long period of time but for the large involvement(more than 30%) and especially lateral lesion, aggressive surgical treatment may be considered even though the early stage of disease for the prevention of progression. However it will need more period of time to accurately compare the results of various methods of treatment.

The 68 cervical cerclage operations of incompetent internal os of the cervix(IIOC) were performed at the Taegu Catholic Medical Center from Jan. 1, 1990 to Dec. 31, 1995. The results of this study were as follows: 1. The incidence of operation for IIOC was 0.23% of total delivery. 2. Highest number of IIOC was observed in the age group of 25 to 29, and the average number of pregnancy before operation was 4.1. 3. The significant contributory factor was previous history of the induced or spontaneous abortion. 4. In all cases, cerclage method was McDonald operation. 5. The average fetal salvage rate after operation was 82.5% and from the 14th week to 16th week of gestation(43 cases), the success rate of operation was 85%. 6. The causes of operation failure were premature labor in 6 cases(55%), premature rupture of membrane in 3 cases(27%) and abortion in 2 cases(18%) in order.

BACKGROUND : Lipoprotein(a)[Lp(a)] may be an independent risk factor for macrovascular disease in middle aged populations, but in elderly populations, Lp(a) levels to predict macrovascular risk is controversial. The purpose of this study is to evaluate the association of macrovascular disease with Lp(a) levels and lipid change in the elderly. METHODS : We have examined Lp(a) levels, lipid change and clinical, biochemical profile in 114 patients with macrovascular disease and 55 control subjects. Macrovascular disease was defined as ishemic heart disease and/or peripheral vascular disease, peripheral vascular disease was defined as arteriosclerosis obliterans, diabetic foot and/or cerebrovascular disease. RESULTS : Hypertension, diabetes were more prevalent and median Lp(a) levels, fasting blood glucose and HDL-cholesterol were significant higher in patients with macrovascular disease than control subjects, but there were no significant differences in age, body mass index, total cholesterol and triglycerides levels. Lp(a) levels were positively weak correlated with fibrinogen levels, but not correlated with age, body mass index, total cholesterol, HDL-cholesterol, LDL-cholesterol and triglycerides levels. In logistic regression analysis, there was no independent risk factor for ischemic heart disease, whereas diabetes, hypertension and low HDL-cholesterol levels were independent risk factors for peripheral vascular disease. CONCLUSION : Serum Lp(a) levels was not independent risk factor for macrovascular disease, but diabetes, hypertension and low HDL-cholesterol levels were independent risk factors for peripheral vascular disease. Therefore, the relationship between Lp(a) and lipid change and macrovascular disease in the elderly were different from middle aged subjects.

Recently, the number of cataract surgeries has rapidly increased. This study was devised to evaluate the post-operative daily life behavior and degree of satisfaction in the patients who underwent cataract surgery two or more years ago. Of 400 patients who underwent ECCE with IOL implantation, 125 patients[31%]replied to the mail questionnaire consisted of thirty questions. Hospital records were also reviewed. 84%of the patients were satisfied with outcomes of cataract surgery, which was significantly correlated with current visual acuity[p<0.01]. Degree of satisfaction was significantly higher in patients with bilateral surgery compared with those with unilateral surgery[p<0.05]. Age, sex, occupation, economic and general health status were not significantly associated with degree of satisfaction. As for life behavior, discomfort while driving an automobile was the most common complaint, especially in the patients who underwent unilateral surgery. Concerning ocular symptoms, many patients complained of foreign body sense, epiphora, glare, fatigue, and near vision discomfort. We reconfirmed that the decision to perform cataract surgery should be made with careful consideration of long term prognosis and above results.

A study has been made on the skin response of mouse hind limb to radiation to evaluate the difference of skin response to superfractionation and conventional fractionation schedules, and to optimize the time interval betweenfractions and the dose per fraction in the superfractionated irradiation. 96 mouse hind limbs were dvided into 12groups and were irradiated with 10 consecutive fractions by intervals of 6, 12 or 24 hours and dose per fractionsof 400, 500, 600 or 700 rads. The skin changes of the irradiated hind limb were observed for 30 days and the skin response were analyzed. The results are as follows; 1. There was no significant difference of early skin response along the time interval, from 6 to 24 hours, up to 600 rads per fraction. 2. Mean duration to maximum skin reaction in superfractionation (15.48±2.80 days) is shorter than in conventional fractionation (18.05±3.20 days)by 2.57 days. (p<0.05). 3. Optimum time interval betwen fractions in superfractionation may be 6 hours or less. 4. Optimum dose per fraction in superfractionation may be 500 rads or less.
