Abdominal ultrasonography was performed in 25,622 adults during the period from July 1992 to June 1995 at the Helth Care Examination Center. The renal masses detected and identified by abdominal sonography were investigated to estimate the incidence of each identification. Renal masses were found in 562 cases(2.19%). Of five hundred and sixty two cases, 555(98.75%) were cystic masses and seven(1.25%) were solid masses. Of five hundred and fifty five cystic masses, 550 were simple cyst(97.86%), four polycystic kindney(0.71%) and one cystic renal cell carcinoma(0.18%). Of seven solid masses, two were angiomyolipoma(0.36%) and another four were renal cell carcinoma(0.71%). The rest one case revealed equivocal finding on an ultrasonography, but the patient refused further study. Although the study population was not a random sampling, the incidence of simple cyst was 2,146 per 100,000 in adult and that of renal cell carcinoma was 19 per 100,000 in adult. Furthermore, ultrasonography is a useful tool for screening the renal carcinoma at the low cost.

Three cases of severe spinal kyphotic deformities were treated with Halo-pelvic Apparatus. Among these three cases, two were tuberculous kyphotic deformities involving the thoracolumbar vertebrae with paraplegia. And the other one was cervical kyphotic deformity due to neurofibromatosis with neurologic involvement. The following results and considering problems were obtained. 1. Two cases of tuberculous kyphosis, 130° and 115°, were corrected to 120° and 100° respectively. And one case of neurofibromatic kyphosis, 90° was corrected to 53°. 2. Among two cases of tuberculosis in which the one was revealed full neurologic recovery, and the other resulted in permanent paraplegia. And a case of neurofibromatosis was fully recovered neurologically. 3. Total period of immobilization with Halo-pelvic Apparatus was 16, 18, 18 weeks in three cases respectively, but there was no avascular necrosis of odontoid process. 4. One case of neurofibromatosis with anterior spinal fusion revealed no loss of correction of kyphosis. But two cases of tuberculosis without anterior spinal fusion showed loss of correction of kyphosis, 20° respectively. 5. Removal of internal kyphosis was not easy, because it is likely to injury the blood supply to spinal cord. 6. During distraction, severe pain was noticed in the rib cage, which prevented further distraction. 7. After 9 weeks, ambulation with Halo-pelvic Apparatus was hindered with pain due to pelvic pin loosening. 8. In order to prevent loss of correction of kyphosis, it was considered that anterior spinal fusion should be followed by posterior spinal fusion.

Total Hip Replacement is well documented and widely used procedure for painful arthritic hip in past two decades and each year still seems to be increased in numher of total hip replacement. And recently, there is a few reports of follow-up study on total hip arthroplasty in our country. The aim of this study was to present the clinical material which was performed on 27 hips of 21 patients who were treated at Dept. of Orthopedic Surgery. College of Medicine, Chungnam university from jan, 1979 to Jan. 1982. The longest follow up was 4 years, shortest was 8 months, average time was 2 years and 8months The results were obtained as follow; 1. The age incidence ranged from 26 to 69 years old, and average were 47 years old. 2. There were 17 males (81%) and 4 females (19%). 3, The causes of hip disease were mostly avascular necrosis of the femoral head (67%). 4, The most commonly used prosthesis were Muller type with trochanteric ostcotomy approaches. 5. Several complications were found: perforation of acetabulum with bone cenent in pelvis, postperative pneumonia wire breakage and painful bursitis around the trochanteric area which was on osteotomy sites. 6. Postoperative functional evaluation was evaluated by method of d'Aubigne and Postel, and improved from 10.0 scores to 15.8 scores. Relief of the pain is the most effect of the total hip replacement in this study, But case are not enough to more detail evaluation, especially, the problem of loosening of stem, acetabular cup wearing and heterotopic bone formation after total hip replacement.

We used the health screening data of some rural and urban residents to examine the cross-sectional association between leukocyte count and hypertension. The 206 male and 203 female rural residents were selected by multi-stage cluster sampling method in Kyungsan-Kun area of Kyungbuk province in 1985 and 600 urban residents were selected by the same sampling method as the rural residents in Daegu city of the same province in 1986 compatible with age-sex distribution of Daegu city of 1985 census, but of whom 384 actually responded. The rest of 600 were replaced by age and sex with those who were members of the medical insurance plan visiting the health management department of the university hospital to get the biannual preventive medical checkups. Excluded in the analysis were those having hypertensive history, diseases and extreme outlying values of the screening tests, leaving 373 rural and 571 urban residents. Leukocyte count was measured with ELT-8 Laser shadow method and the unit cells/mm3. Blood pressures were determined with an aneroid sphygmomanometer with pre-standardized method and hypertensives were defined as those showing systolic blood pressure more than 140 mmHg and / or diastolic blood pressure more than 90 mmHg. Total residents pooled (N=944) showed a significant difference between hypertensives and normotensives (6965.93+/-1997.01 vs 6490.61+/-1941.32, P=0.00) and in rural residents was noted the similar significant difference (P=0.03). None of significant differences were noted in any stratum stratified by residency and sex. Compared to the lowest quintile of WBC, 2/5 quintile showed odds ratio 0.99 (95% CI 0.90-2.21), 4/5 quintile 1.76 (95% CI 1.14-2.72), and highest quintile 1.80 (1.15-2.82) in the total residents. Likelihood ratio test for linear trend for in indicated a significant trend (x2 trend=5.53, df=1, P<0.05). There were no other significant odds ratios compared to the lowest quintile of WBC in strata stratified by residency and sex. The odds ratios in total residents which had showed significant odds ratios became nonsignificant and of reduced magnitude after controlling age, frequency of smoking and drinking with multiple logistic regression. In each stratum, it changed magnitudes of odds ratios slightly and unstably. None of the trend tests showed any significant trend. These results suggest that the Friedman et al's finding of association between leukocyte count and hypertension may be due to an statistical type I error result in from the data dredging in an exploratory study, in which more than 800 variables were screened as possible predictors of hypertension.

Aberrant breast tissue is usually found in proximity to the normal breast, that is, in the axillary, sternal or clavicular regions. Carcinoma occurs more frequently in the aberrant tissue of the axilla than the extra-axillary site though the overall incidence of tumors of aberrant breast tissue is low. To our knowledge, studies regarding the carcinoma of aberrant breast tissue of the extra-axillary site have been reported rarely. Here we report a recent case of carcinoma originating from the extra-axillary aberrant breast tissue, presenting as a subcutaneous nodule on the right upper anterior chest wall. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be suspected for breast carcinoma as a differential diagnosis and treated properly.

In the summer of 1969 from July through October, authors carried out a study of susceptibility in adult female bed bug(Cimex lectularius) in order to ascertain any development of resistance to insecticides in Korea. The test to DDT and Dieldrin was performed in laboratory by the continuous exposure of residues method, with standard impregnated paper used for adult mosqitoes. Some results so far obtained can be summarised as follows: LC(50) were 2.839% in DDT and 0.167% in Dieldrin. The resistance has been arisen 2.4-2.9 times in DDT and 1.6-2.4 times in Dieldrin as compared with London laboratory strain, but they were susceptible 1.4 times in DDT and 180 times in Dieldrin as compared to Israel resistance strain.

Hyperglycemia has been reported to worsen the tolerance of the brain to ischemia, and it has therefore been recommended that patient undergoing neurosurgical procedures not receive glucose-containing solutions. Since ischemic events lead to increased lactate production and accumulation and hence neuronal damage, the present study was designed to test the effect of insulin-induced hypoglycemia and decreased lactate by 2-Deoxyglucose and Dichloroacetate on focal cerebral ischemia in rats. Although the pre and post-ischemic blood glucose levels of control group and Dichloroacetate group showed no change, the blood glucose level of 2-Deoxyglucose group showed a significant increase(p=0.001), and insulim group a significant decrease(p=0.004). The reducing effects on the infarct zone in these three treated groups were found with statistical significance. As compared with control group, the tissue lactate levels of treated groups were decreased in both infarct zone and border zone but these data did not show statistical significance. From these observations, it is suggested that reduction of lactate production and accumulation could be beneficial by affording neuronal protection in ischemic tissues.

PURPOSE: Extracapsular invasion (ECI) of nodal metastasis is reported to be a prognosticator of colorectal cancer. However, limited knowledge exists about the prognostic value of ECI in stage III rectal cancer. METHODS: From January 1996 to June 2004, 202 stage III rectal cancer patients who underwent surgery were enrolled in this study. The patients were divided into two groups according to ECI (patients with ECI, ECIP, n=122; patients without ECI, ECIN, n=80). The potential prognostic factors were compared in a Cox model. RESULTS: Of 916 positive nodes examined, ECI was seen in 46.7% of the positive nodes. The univariate comparison between the two groups revealed the five-year results after a median follow-up of 48.0 mo. The local control rate of ECIP did not show a significant difference from that of ECIN (77.0% vs. 85.4%, P=0.550). The disease-free survival rate and the overall survival rate differed for the two groups, with rates of 44.1% and 50.0% for ECIP and 70.4% and 63.2% for ECIN (P<0.001, P=0.049, respectively). The impact of ECI on the disease-free survival was confirmed in a Cox model. In a subgroup analysis, no significant differences in the recurrence and the survival rates were seen between the N1 ECIP and the N2 ECIN subgroups. CONCLUSION: Although ECI is not a risk factor for survival and local relapse, ECI is a prognosticator of overall recurrence. Based on these findings, more aggressive adjuvant treatment seems to be needed for decreasing the overall recurrence in stage III rectal cancer with ECI.

OBJECTIVE: The operative indications on cerebellar hemorrhage have been controversial especially when the patient condition is grave. Therefore we investigated whether it can be justifiable if we perform the surgery in poor clinical grade. METHODS: Clinical records and computerized tomography(CT) films of the 89 patients, who were undergone hospital treatment due to spontaneous cerebellar hemorrhage between May 1997 and May 2004, were retrospectively researched. RESULTS: The study population consisted of 36 males and 53 female patients. The mean age was 65years (range 23~89). As a result of treatment, the patients, whose Glasgow coma scale(GCS) score were higher, showed better outcomes (p=0.001). 13 patients (14.6%) were below 5 in GCS score and 10 patients of these were operated. Among 10 patients, 4 patients (40%) showed good outcome and 5 patients (50%) had been dead. 3 patients (60%) of these dead patients had the findings of intraventricular hemorrhage, fourth ventricular obliteration and hydrocephalus in CT scan. CONCLUSION: This study suggests that operation may be justifiable in clinically poor grade patient with spontaneous intra cerebellar hemorrhage.
