The effect of Atenolol on the blood pressure were studied in 31 cases of essential hypertension and on the effect of plasma renin activity in 8 cases. There were 8 cases of male with age 49.5(42-70) and 23 cases of female with age 49(35-71) years. 27 cases of 31 cases were untreated hypertensive patients and 4 cases were refractory to hypotensive drugs of diuretics and vasodilators. The Atenolol 50mg once-daily was given to all patients orally for 3 weeks. The blood pressure, heart rate, ECG and symptoms were checked in one week interval. In 8 cases, the plasma renin activity was measured by Dainabot Kit before and after one week medication. The results were as follows: 1. In 27 cases of untreated hypertension, the control blood pressure was 182.9/11.4mmHg in average. The blood pressure decreased in average by 18.3/11mmHg in one week, 23.7/15.9mmHg in two week and 21.5/10.5mmHg in three week. The heart rate also decreased by 7.4/min. in one week, 14.9/min. in two week and 7.8/min. in three week. These data showed considerable reduction of blood pressure and heart rate with 50mg Atenolol once-daily. 2. The basal plasma renin activity after one week medication was reduced by 46% in 8 cases and this data showed considerable reduction regardless control level of basal plasma renin activity. 3. There were considerable blood pressure reduction by adding Atenolol 50mg once-daily to diuretics and vasodilator to which patient's blood pressures were refractory. 4. There was no orthostatic hypotension or serious side effect by Atenolol medication.

Aggressive angiomyxoma (AAM) is a rare, benign tumor. It usually involves the connective tissue of the perineal regions in women of reproductive age. In this report, we present a case of AAM in a 66-year-old female, which presented itself as a retrovesical tumor on pelvic magnetic resonance imaging and caused lower urinary tract symptoms. The tumor was resected en bloc and the patient's voiding symptoms disappeared.

Combined hepatocellular carcinoma and cholangiocarcinoma is found at a frequency of 1.0~6.3% in resected primary hepatic tumors. However, the case of double cancers of hepatocellular carcinoma and cholangiocarcinoma that are discovered synchronously in different lobes of a liver is very rare. We experienced a case of a 74-year-old man who was found to have hepatocellular carcinoma and cholangiocarcinoma in different lobes of the liver, which were accompanied by early gastric cancer. To our knowledge, this is the first case report of double primary hepatic cancers accompanied with early gastric cancer. The pathogenesis and previous related reports of these lesions are discussed.

BACKGROUND/AIMS: Detection of proximal serrated polyps (PSPs) is increasingly recognized as a new qualitative target for colonoscopy. The aims of this study were to assess the detected prevalence of PSPs and synchronous adenomas in an asymptomatic average-risk screening cohort and to evaluate potential factors associated with detection of PSPs. METHODS: The study included 1,375 asymptomatic average-risk Korean patients (aged 50 years or older) who underwent screening colonoscopy. In total, 1,710 polyps were evaluated pathologically. RESULTS: The overall PSP detection rate (PSPDR) was low at 3.1%, despite high polyp (54.0%) and adenoma detection rates (ADRs, 43.5%). ADR did not correlate with PSPDR, but it was strongly correlated with PDR (r=0.810; p<0.001). Patients with PSPs were more likely to have longer withdrawal time and more proximal colon adenomas than patients without PSPs (adjusted odds ratio [OR], 1.19; 95% confidence interval [CI], 1.09 to 1.31; p<0.001) (adjusted OR, 2.03; 95% CI, 1.06 to 3.88; p=0.031, respectively). CONCLUSIONS: The detected prevalence of PSPs was low (<5%) in an asymptomatic average-risk screening Korean population, despite the high prevalence of conventional adenomas. A longer mucosal inspection of the proximal colon may serve as a practical method to enhance detection of PSPs.

PURPOSE: p53 gene is a well-known suppressor gene of tumor. And the p53 protein expression in immunohistochemical staining acts a role as a prognostic indicator in prostate and bladder tumor. However, the validity of p53 protein expression was not determined as an independent factor of prognosis in renal cell carcinoma(RCC). Furthermore, there were not enough studies about whether the expression of p53 protein plays a role as a prognostic indicator in RCC or not. Therefore, we evaluate the prognostic significance of p53 protein expression in RCC. MATERIALS AND METHODS: To evaluate the prognostic significance of p53 immunohistochemical staining in RCC, paraffin embedded specimens taken from 84 patients with RCC were studied from January 1982 to April 1997, retrospectively. In addition to the prognostic significance of p53 immunohistochemical staining, correlation between p53 immunohistochemical staining and pT category, nuclear grade, and histologic type was studied. RESULTS: The expression rate of p53 protein was 19.0%(16/84). The most important prognostic indicator of RCC was pT category(relative risk=2.19, p=0.007). And the second important prognostic indicator was the expression of p53 protein(relative risk=1.82, p=0.017). Nuclear grade had prognostic significance(p=0.027) but was not an independent prognostic indicator. The expression of p53 protein did not correlate with pT category, nuclear grade or histologic pattern. CONCLUSIONS: We have shown that the expression of p53 protein in RCC is the second most important prognostic indicator. In conclusion p53 immunohistochemical staining can be used to predict the prognosis in patients with localized RCC after radical nephrectomy.

Renal cell carcinoma (RCC) in autosomal dominant polycystic kidney (ADPKD) is rare. To date, 54 cases of RCC in ADPKD have been reported. Among these, only 2 cases have different histologic types of RCC. Here we describe a 45-year-old man who received radical nephrectomy for multifocal RCC with synchronous papillary and clear cell histology in ADPKD and chronic renal failure under regular hemodialysis. The case reported herein is another example of the rare pathological finding of RCC arising in a patient with ADPKD.

PURPOSE: The prognostic factors influencing the survival rate of patients with localized renal cell carcinomas were evaluated. MATERIALS AND METHODS: The records of 100 patients that had undergone a radical nephrectomy for renal cell carcinomas, and who were pathologically diagnosed with T1N0M0 and T2N0M0 carcinomas, between January 1990 and January 2002, were reviewed. The survival rate according to each prognostic factor, such as T1 or T2 stage, nuclear grade, histologic type, microscopic vascular invasion, the expression of p53 protein and the expression of Human Erythrocyte Glucose Transporter (Glut-1), was analyzed by the Kaplan-Meier method. RESULTS: Among the 100 patients, metastases occurred in 11 and death in 10. The 5-year survival rates of the T1 and 2 were 84 and 89%, respectively. According to the Fuhrman grade, the 5-year survival rates for grades I, II, III and IV were 100, 87, 84 and 64%, respectively. According to the histologic type, the 5-year survival rates for the conventional type, papillary type and chromophobe type were 84, 100 and 88%, respectively. There was no significant difference in the survival rate between the groups, according to the stage, Fuhrman grade and histologic type (p>0.05). No statistical differences were noted between the two groups for microscopic vascular invasion, the expression of p53 protein and the expression of Glut-1 (p>0.05). CONCLUSIONS: Localized renal cell carcinomas treated by a radical nephrectomy had a good prognosis (5-year survival rate: 85%). Fuhrman nuclear grade IV and microscopic vascular invasion tended to have poor prognoses.

OBJECTIVES: We carried out tests for neurobehavior by using WHO-NCTB (neurobehavioral core test battery) and Perdue pegboard score test to identify differences between lacunar infarction cases and controls. METHODS: Among the subjects who underwent MRI between February 2001 and March 2002 in a university hospital located in Seoul and who were diagnosed only as lacunar infarction without any intracranial disease, 46 patients were selected as cases (male: 21, female: 25). Controls were selected who had no cerebrovascular disease on MRI by matching age (5 years), gender, and education (2 years) in a ratio of 1: 1. Among WHO-NCTB, the following 5 tests and Perdue pegboard score test were used to categorize the study subjects: digit and symbol matching, simple reaction time, Benton visual retention, digit span, and Pursuit aiming test. RESULTS: Among the above 6 tests of neurobehavior, lacunar infarction cases showed lower score than controls except for the simple reaction time test. As the controlling variables of multivariate analysis in the stepwise regression analysis, the followings were selected due to their significant association: age, education, BMI, gender, drinking, exercise, and systolic blood pressure. From multivariate regression analysis, there was significant difference (p< 0.05) between lacunar infarction cases and controls in digit and symbol matching, Benton visual retention, digit span, pursuit aiming, and Perdue pegboard score test, but not in the score of simple reaction time test. CONCLUSIONS: We suggest that the above 5 tests for neurobehavior, with the exception of the simple reaction time test, might be used as the basis for recommendation of further treatment and other neurological tests by the earlier detection for neurological abnormality in lacunar infarction.
