PURPOSE: It has been generally known that prostatic volume is increased related to aging process and changing in hormonal environment, so lower urinary tract symptoms develops. But, our experience has revealed the decrease of prostatic volume in many cases with lower urinary tract symptoms despite aging. MATERIALS AND METHODS: The numbers of patient underwent TRUS were 301 cases. Among the patients who had visited urologic outpatient clinic from march, 1993 to march, 1996, transrectal ultrasonography of prostate was applied to patient with following conditions. 1) over 8 in IPSS with or without enlarged evidence from digital rectal examination 2) enlarged evidence from digital rectal examination 3) no symptomatic relief after 2weeks therapy with alpha blocker 4) when the patient wants more evaluation. RESULTS: Decrease of prostatic volume were shown in 66cases(22%) despite lower urinary tract symptoms. CONCLUSIONS: In our experience, many patients with lower urinary tract symptoms showed decrease of prostatic volume. So, we expect that many more cases of decrease of prostatic volume can be seen among asymptomatic cases with age. Because we can guess that prostatic volume can be influenced by racial differences and dietary habit, we also believe that further evaluation and investigation of this nature is needed.

The Ilizarov fixator allows significantly more axial motion at the fracture site than the conventional monofixators. But the transfixing wires have inevitable problems of soft tissue impalement. Therefore the Rancho mounting technique, replacing the transfixing wires with half pins, has become a common place. But the increment of the axial stiffness secondary to replacing transfixing wires with half pins has not been defined clearly yet. The authors measured the axial stiffness of the Ilizarov fixator and two different configurations of the Rancho frame. The group I frame was the Ilizarov fixator composed of four rings and two transfixing wires on each ring. The group II frame was the Rancho frame and it was constructed same as the Ilizarov frame but a transfixing wire was replaced with a half pin from two central rings respectively. The group III frame was another type of Rancho frame which was constructed same as the second group but the remaining transfixing wire was replaced with a half pin from the two central rings respectively. The axial stiffness of the Group I , II and Group III frames were 71.54+/-7.21N/mm, 89.65+/-6.42N/mm, 101.01+/-7.92N/mm respectively. The axial stiffness difference between the Group I frame and the Group II frame was statistically significant(p<0.01). Also the difference between the Group I frame and the Group III frame was statistically significant(p<0.01). This study shows that the replacement of two transfixing wires with two stainless half pins resulted in significant increment of the axial stiffness of the Ilizarov frame.

Cardiac output depends on the ability of systolic ejection and diastolic filling of the heart. M-mode echocardiography can provide accurate clinical assessment of left ventricular systolic and diastolic functions. To see whether there are changes of the left ventricular function in asymptomatic hypertensives and if any kind of dysfunction and whether any relationship between the pattern of the ventricular hypertrophy and type of ventricular dysfunction exists, the authors examined the systolic and diastolic function indices of the left ventricle in 50 normotensives and 88 hypertensives composed of 18 patients without left ventricular hypertrophy(group 1), 40 patients with disproportionate septal thickening (group 2) and 30 patients with concentric left ventricular hypertrophy(group 3). Obtained results were as follows : 1) Blood pressure & left ventricular mass index were increased significantly in each hypertensive group compared to normal control. 2) Ejection fraction & fractional shortening in the hypertensive groups were not different from the normotensive control group. 3) Left ventricular isovolumic relaxation time(A2D time) was prolonged in each hypertensive group, especially in group 3. 4) Left atrial emptying index (AEI) was decreased in each hypertensive group. 5) Left ventricular percent ventricular A wave (% VAW) was increased in all hypertensive groups. Above study suggested that the left ventricular diastolic function could be impaired in the hypertensives without associated systolic dysfunction, and the degree of the diastolic dysfunction was not much affected by the type of left ventricular hypertrophy, but the more prolonged A2D time in the concentric hypertrophy group.

Two factors of the ventricular function, systolic contractile and diastolic relaxing functions, cooporate in pumping the adequate blood volumes to suffice bodily demands. In some hypertensive patients with marked left ventricular hypertrophy, the intact systolic function of the ventricle associated with clinical symptom of congestive heart failure(CHF), which is considered to be a consequence of diastolic dysfunction. In this study 10 hypertensive patients(group A) complaining of exertional dyspnea or chest pain with increased left ventricular mass index and normal systolic function and 6 normotensive controls(group B) were examined by cardiac catheterization and echocardiography to assess the left ventricular systolic and diastolic function and ventricular responses to constant infusion of nitroprusside. Various systolic and diastolic function indices were measured by cardiac catheterization and echocardiography. 1) The ejection fraction(EF), fractional fiber shortening, mean velocity of circumferential fiber shortening, left ventricular(LV) peak+dp/dt, change of slope of LV peak systolic pressure-volume and pressure-dimension relations in group A were not different from those of group B in the resting states. 2) Diastolic dysfunction was evidenced by prolonged A2D time, decreased OR slope, decreased peak negative dp/dt and increased diastolic time constant 'T' in group A. 3) Cardiac index by thermodilution method was negatively related to left ventricular mass index(LVMI) measured by echocardiography, whereas time constant T was positively related to LVMI. 4) With constant infusion of nitroprusside, LV systolic pressure, LV end-diastolic pressure and pulmonary arterial pressure were decreased, and left ventricular end-systolic stress and stroke work index(SWI) derived from left ventricular pressure-volume loop area were decreased, EF was increased, but time constant T was prolonged and cardiac output(CO) by thermodilution method was decreased in group A. 5) In group B, with constant infusion of nitroprusside, EF, SWI and CO were pratically unaffected and time constant T was not prolonged significantly. These reults suggest that patients with hypertensive hypertrophic left ventricle is associated with diastolic dysfunction, which could further be exacerbated by a vasodilator such as nitroprusside.

The thoracic and lumbar spine fractures were usually combined with neurological deficit. But the prognostic factors in degree of neurological damage and process of the recovery are controversial. The purpose of this study is to evaluate the factors affected neurological injury and the recovery. The 31 cases who had been performed surgical interventions due to traumatic thoracic or lumbar spine fractures with the neurological deficits were studied according to the radiographic findings of the spinal columns and neurological changes of the injured cord and/or the roots. The duration of mean follow-up was 32.6 months, and all cases were evaluated by motor index score and Frankel grade. Total cases were divided into complete paralytic (N=8) and partial paralytic(N=23) group. In incomplete paraplegia group, the neurological recovery rate was better than complete group(P < 0.001) and neurological recovery period was shorter than complete group (P=0.005). The neurologic deficits according to the Frankel grade were higher in Chance fracture, flexion-distraction and translation (complete paraplegia: 4/7 cases, 57.1%) than unstable bursting fracture (complete paraplegia: 4/24 cases, 16.7%)(P=0.031). The recovery rate of Chance fracture, flexion-distraction and translation were worse than unstable bursting fracture (0.001). The fracture which occurred in T5-11 showed higher incidence of complete paraplegia(75%) compared with that of the T12-L1(30.8%) & L2-4(7.1%)(p=0.021). The neurological recovery in motor index score in L2-4 was higher than T5-11 or T12-L1(P=0.0017). There was no correlation in kyphotic deformity and anterior body height loss between complete and incomplete paraplegia groups. But the A-P diameter of compromised neural canal showed significant difference between complete and incomplete paraplegia group(P=0.027)

PURPOSE: It is not clear that the development of glomerular injury and aggravation by tumor necrosis factor alpha (TNF-alpha) is related to intrarenal or serum concentration of TNF-alpha. So, we studied the relationship between the concentration of TNF-alpha and aggravation of glomerular damage in the Henoch-Schonlein nephritis(HSN) and idiopathic nephrotic syndrome(INS). METHODS: We collected the sera and urines of 21 patients with Henoch-Schonlein purpura(HSP) and 22 patients with INS visited Chungbuk National University hospital from March 1998 to March 2001. The concentration of TNF-alpha in the sera and urines were measured by sandwich ELISA. RESULTS: Serum TNF-alpha levels in the HSP patients with renal involvement were significantly higher than those without renal involvement(P=0.009). But urine TNF-alpha levels have no correlation with renal involvement(P=0.088). In the HSN patients, proteinuria have a significant correlation with serum TNF-alpha levels(P=0.004) but less correlation with urine TNF-alpha levels(P=0.053). Otherwise, proteinuria have no correlation with serum TNF-alpha levels(P=0.763) but have a significant correlation with urine TNF-alpha levels(P=0.007) in INS. CONCLUSION: These result suggest that the serum concentration of TNF-alpha would be important to glomerular involvement in HSP. And, it is interesting that proteinuria shows a significant relation with serum TNF-alpha levels in the HSN, but with urine TNF-alpha levels in the INS. This means the major production of TNF-alpha may be originated by extrarenal inflammation in the HSN and by intrarenal tubulo-interstitial damage due to proteinuria in the INS.

BACKGROUND: White coat effect (WCE) and white coat hypertension (WCH) are relatively prevalent in clinical situation (20 - 57% of WCH in the hypertensive population). The aim of this study was to analyze the determinant factors of WCE. METHODS: A prospective study was carried out in outpatient clinic in a consecutive hypertensives without receiving pharmacologic treatment. Twenty-four hour ambulatory blood pressure monitoring (ABPM) was performed following more than two resting blood pressure (BP) determinations carried out with the interval of 1 - 2 weeks by mercury sphygmomanometer. WCE was calculated for systolic and diastolic BP as the difference between a clinic BP (CBP) and an average daytime ambulatory BP (ABP). WCH was defined as;BP in the clinic > or = 140/90 mmHg with a mean daytime BP by ABPM < or =137/< or =89 mmHg. RESULTS: 1) Two hundred thirty-five patients (mean age 49.7 years, females 74%) were studied. Thirty-seven percent in male and forty-six percent in female patients fulfilled WCH criteria. 2) CBP was significantly correlated to daytime ABP (systolic BP;r=.47, p<.001 and diastolic BP;r=.65, p<.001). 3) The magnitude of WCE was greater in the group of WCH (28.9+14.6/19.3+6.9 mmHg) than ambulatory hypertensives (15.1+15.7/13.0+8.2 mmHg) (p<.001). 4) The magnitude of WCE is significantly correlated with female (r2=.12, p<.001) and the stage of CBP according to JNC-V (r2=.23, p<.001) in systolic BP, the stage (r2=.08, p<.001) in diastolic BP, and the stage (r2=.09, p<.001) and weight (r2=.15, p<.01) in mean BP. CONCLUSIONS: The magnitude of WCE in essential hypertension diagnosed at the clinic is significantly correlated with female, the magnitude of clinic BP, and weight.
