BACKGROUND: Coronary blood flow shows phasic and diastolic dominant flow pattern in normal coronary artery, which can be changed in coronary artery stenosis. We measured and analysed coronary blood flow velocity by Doppler-tipped guidewire to clarify the change of flow pattern in the proximal and distal segments of coronary narrowings. METHODS: Coronary flow velocity were measured by 0.018 or 0.014 inch Doppler-tipped guidewire in 14 paients, 17 sites(LCS 11, RCA 6) in the proximal and distal segment of coronary narrowings, during coronary angiography or coronary angioplasty after bolus intracoronary infusion of 20microg nitroglycerine. Coronary flow reserve also measured after adenosine intracoronary infusion(LCA 12gmicrog, RCA 6microg). Perent stenosis of coronary artery was measured by digital cailper in 2 different projections and averaged. RESULTS: 1) The was no significant correlation between percent stenosis and proximal distal velocity ratio(P/D) ration(r=0.56. P>0.05). 2) Average peak velocity(APV, cm/sec) and diastolic artery, respectively(p<0.01) Distal APV was significantly lower than proximal APV(p<0.01) but DSVR showed no significant difference(P>0.01). 3) Coronary flow reserve(CFR) was significantly lower in significant coronary stenotic patients compared to insignificant stenotic patients(1.8 vs 3.6, P<0.01). CONCLUSION: Coronary flow velocity measurement by Doppler dipped guidewire gave us physiologic information. We think it could be used as an important tool to assess the significance of the intermediate coronary narrowings and the effect of conorary angioplasty.

PURPOSE: To determine whether the compression technique is a valuable additional method for differentiating between benign and malignant breast masses. MATERIALS AND METHODS: The ultrasonographic findings of 95 benign and 53 malignant masses, all pathologically proven, were prospectively analyzed with regard to five diagnostic criteria: shape (regular/irregular), retrotumoral acoustic phenomena (posterior enhancement/posterior attenuation), internal echo pattern (homogeneous/inhomogeneous), compression effect on shape (distortion/no change), and compression effect on internal echo pattern (more homogeneous/no change). RESULTS: The number of cases of benign and malignant masses, respectively, was as follows: regular / irregular shape: 84/11, 9/44; posterior acoustic enhancement/posterior attenuation: 82/13, 16/37; homogeneous/inhomogeneous internal echo pattern: 78/17, 14/39; distortion/no change in shpae: 76/19, 5/48; and more homogeneous/ no change in internal echo pattern: 71/24, 3/50. For all diagnostic criteria for the differentiation of benign and malignant masses, the differences were statistically significant (p<.05). CONCLUSION: Ultrasonography is helpful for differentiating between benign and malignant breast masses. The compression technique is a valuable additional diagnostic method.

BACKGROUND: Most surgical patients experience preoperative anxiety. This anxiety can effect the amount of preanesthetic medication and anesthetic agents needed, and contribute to postoperative pain. Music has been recognized as a way to reduce anxiety and fear. The effect of hymn and sutra-chanting on the preanesthetic patient's anxiety in the operating room were studied. METHODS: 98 patients were divided into two groups according to the religionist or atheism. Group I(n=50, religionist) and Group II(n=48, atheism) listened to hymn or sutra-chanting according to the patient's religion and choice. At ward, hemodynamic variables including systolic and diastolic blood pressure and pulse rate were measured as control values. Hemodynamic variables and measurements of anxiety score with Hamilton anxiety rating scale were made at pre-music and post-music in the operating room. Also, patient's response to the music was measured on the postoperative 5-6th day. RESULTS: There were no difference between ward, pre-music, and post-music in terms of systolic pressure, diastolic pressure and pulse rate except the systolic pressure at pre-music that is grater than that of controls in both groups. Both group, anxiety score at post-music was significantly lower than that of pre-music (10.2+/-3.4 vs 4.4+/-2.9, 11.0+/-3.2 vs 5.7+/-3.1). At post-music, anxiety score in Group I showed significant reduced compaired with Group II (p<0.05). Patients showed relatively good satisfaction with music in both groups. CONCLUSION: The results suggest that music with hymn and Sutra-chanting were effective to reduce preanesthetic anxiety in both religionist group and atheism group.

Multilocular cystic renal neoplasm of low malignant potential (MCRNLMP) is a rare subtype of renal cell carcinoma that has a favorable outcome. Most cases of MCRNLMP usually present as distinct multilocular cystic lesions; however, they may appear as small complicated cysts with hemorrhagic components. Herein, we present a case of MCRNLMP and provide a review of the literature.

The lesions on computerized tomography (CT) scan were evaluated in 7 cases of conduction aphasia. On Modified Westem Aphasia Battery (MWAB), all the patients showed fluent aphasia with some paraphasic errors, good comprehension, marked repetition dificit and variable degree of impairment in naming. The three most common lesions on CT scan were supramarginal gyrus and it's white matter, primary auditory cortex, and insular region, which were involved in 6,5,4 cases out of 7 respectively. Of the three lesions, one or variable combinations of them may be the critical structures for repetition difict in these patients, as has been reported in previous studies. In 5 cases Wermicke area was relatively intact and prominent involvement was seen in only 2 cases, which is thought to be associated with relative preseration foaural comprehension in conduction aphasia.

In recent years, it has been common to use bupivacaine for prolonged operation because of its long duration of action but, besides of this benefits, we always are cautious of using bupivacaine for its possible systemic, toxicity, such as convulsion, myocardial depression. We experienced a case of asthmatic attack right after injection of 0.5% bupivacaine 125 mg for BPB(brachial plexus block) in a 26 year old male patient with chronic renal failure for the revision of a-v fistula. With the administration of aminophylline and oxygen by mask the patient was anounced about delaying operation and the symptoms were gone. Next day with local infiltration of 2% lidocaine operation was done uneventfully.

OBJECTIVES: Excessive daytime sleepiness (EDS) in the elderly is related to cognitive dysfunction. We aimed to analyze the difference in the neurocognitive function between the elderly groups with and without EDS and examine the correlation between sleep parameters and the neurocognitive function in the elderly with EDS. METHODS: Thirty seven subjects who visited Kangwon National University Hospital were recruited. We excluded those who had abnormalities in laboratory examination or chronic systemic diseases. For each subject, a neuropsychological battery in the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) Assessment Packet was applied. Nocturnal polysomnographies were conducted in 16 subjects with EDS. RESULTS: There were no significant differences in the neurocognitive function between EDS positive and EDS negative groups. In the EDS positive group, the amount of stage 1 sleep negatively correlated with scores on Boston naming test, word list memory and Stroop interference, respectively (r=-0.611, -0.583, -0.611). Also, REM sleep amount positively cor-related with scores of word list recognition (r=0.568), and limb movement index negatively correlated with scores of word list memory (r=-0.523). CONCLUSION: The poor sleep quality was associated with impaired language, memory and executive functions. Also, increased limb movements were associated with the memory decline.
