Recently, the proportion of cardiovascular disease as a cause of death in diabetics is in ever increasing tendency. Present study is designed to evaluate the change of myocardial performance by the effect of microangiopathy of diabetics. The measurements of systolic time intervals were obtained from simultaneous high speed recordings(100mm/sec) of electrocardiography, phonocardiography, and carotid pulse tracing in diabetics(male 26, female 31). 1. As the diabetic retinopathy got severe, shortening of LVET and prologation of PEP were noted, but QS2 showed no significant change. 2. PEP/LVET ratio fo diabetics without diabetic retinopathy was significantly higher than that of normal control(p<0.01). 3. PEP/LVET ratio of diabetics with diastolic blood pressure under 95mmHg was significantly higher than that of normal control group(p<0.01), and PEP/LVET ratio of diabetics with diastolic blood pressure over 96mmHg was significantly higher than that of normal control and that of diabetics with diastolic blood pressure under 95mmHg(p<0.01). 4. PEP/LVET ratio of diabetics with proliperative retinopathy was significantly higher than that of normal control and that of diabetics with mild diabetic retinopathy(p<0.01), but this result was not conclusive because of the small case number.

CT has facilitated early recognition and treatment of focal brain injuries in patients with head trauma. However. CT shows relatively low sensitivity in identifying nonhemorrhagic contusion and injuries of white matter. MR is known to be superior to CT in detection of which matter injuries, such as diffuse axonal injury. MR imaging in 14 cases of diffuse axonal injury on 2.0T was studied. The corpus callosum, especially the body portion, was the most commonly involved site. The lesions ranged from 5 to 20 mm in size with ovoid to elliptical shape. T2WI was the most sensitive pulse sequence in detecting lesions such as white matter degeneration, hemorrhagic and nonhemorrhagic contusion. The lesions were nonspecific as high and low signal intensities on T2WI and T1WI respectively. CT showed white matter abnormality in only 1 case of 14 cases. We propose MR imaging as the primary imaging procedure for the detection of diffuse axonal injury because of its multiplanar capabilities and higher sensitivity.

To evaluate the influencing factors on pulmonary venous flow(PVF) pattern, we studied the relationship between PVF and left ventricular ejection fracton(EF), mitral annulus motion(MAM) and transmitral flow using pulsed doppler echocardiography in patients with dilated cardiomyopathy(DCMP), acute myocardioal infarction(AMI), left ventricular hypertrophy(LVH) and atrial fibrillation(AE). Ther results were as follows : 1) In the normal controls(13 cases), two forward flow during ventricular systole(VS) and diastole(VD) and one retrograde flow during atrial systole(AS) were observed. The peak velocity of VS, VD and AS flow was 45.9cm/s, 42.8cm/s and -18.3cm/sec, respectively. The peak VS/VD ratio was 1.1. 2) In patients with DCMP(11 cases), (a) compared to the noraml subjects, the peak velocity of VS flow and VS/VD ratio were were significantly reduced(p<0.005 and p<0.001, respectively) and were positively correlated with ejection fraction(r=0.8 and r=0.7, respectively) (b) in 2 DCMP cases with severe mitral regurgitation, systolic retrograde flow was observed in the pulmonary vein instead of forward VS flow. 3) In 12 AMI cases and 7 LVH cases with normal or slightly diminished left ventricular systolic function but with abnormal diastolic function. (a) the peak velocity of VS flow and peak VS/VD ratio were significantly increased(r<0.005 and p<0.01, respectively). (b) the peak velocity of VD flow is positively correlated with transmitral E/A ratio(r=0.8) and the peak VS/VD ratio was positively correlated with transmitral pressure half time(r=0.8). (c) the peak velocity of retrograde AS flow was significantly increased(p<0.001). (d) there was no correlation between doppler parameters of PVF and left ventricular ejection fraction. 4) In patients with atrial fibrillation(10 cases), VS flow was markedly diminished or absent and only VD flow was observed. Also, retrograde AS flow was not observed. These findings suggest that the pattern of PVF is influnced by LVEF, MAM, transmitral inflow and atrial contraction. However, main contributary factors in determining the pattern of PVF in each disease are diverse according to its main pathophysiology.

In Korea, Kerion celsi caused by T. verrucosum was first reported by Kim et al in the Honam province in 1986. Since then three mare cases have been reported in the Young Nam province. Herein present a case of kerion celsi caused by T. verrucosum from Chungcheong province. The patient, a 7-year old female, showed a 4x 4cm sized, oval, yellow crusted and boggy patch with alopecia on the scalp. She was living on a farm in a rural area of Chungcheong province. Cows on the farm also exhibited similar skin lesions on the buttock. The same T. verrucosum was identified by a characteristic colony morphology on Sabourauds dextrose agar and chains of chlamydoconidia with mycologic stain from scales of lesions of patient and cows. This skin lesion was successfully treated with griseofulvin.

PURPOSE: To determine whether the wall thickening of the maxillary sinus is a characteristic finding in aspergillosis. MATERIALS AND METHODS: In 103 patients, including 26 with aspergillosis, 21 with inverted papilloma (IP), and 56 with unilateral chronic sinusitis, the thickness of the maxillary sinus wall was determined by CT scanning. All cases were proven pathologically, and patients with a history of previous surgery or bone destruction were excluded. Two neuroradiologists retrospectively reviewed the CT scans using bone window settings for sinus wall hyperostosis and the presence of intrasinus calcification. Thickening of the maxillary sinus wall was assessed visually in a semiquantitative manner, and graded as 'none'(absence of thickening), 'mild'(thickening of up to 1.5 times), or moderate to severe(over 1.5 times thicker than normal contralateral sinus wall at its thickest point). RESULTS: Moderate to severe wall thickening was found only in patients with aspergillosis (21/26, 80.8%). Mild wall thickening was seen in two patients with aspergillosis (2/26, 7.7%), in 12 of 21 with IP (57.1%), and in 5 of 56 with chronic maxillary sinusitis (8.9%). Most cases of chronic maxillary sinusits (51/56, 91.1%), 9/21 IP cases (42.9%), and 3/26 cases of aspergillosis (11.5%) showed no thickening of the maxillary sinus wall. Calcifications were found in 18 patients with aspergillosis (69.2%), in no patient with IP (0%), and in one with chronic maxillary sinusitis (1.8%). CONCLUSION: We suggest that 'moderate to severe' wall thickening of the maxillary sinus is the characteristic finding of aspergillosis. Although various sinonasal diseases can cause bone change, CT findings of hyperostosis of the maxillary sinus and intrasinus calcification are very helpful in differentiating fungal sinusitis from other types of chronic inflammatory lesions.
