Annals of Dermatology 1996;8(1):30-33
A 25 year old man presinted with erythematous and inderated plaques on the upper and lower extermities that were preceded by insect bites while traveling in central Africa. The patient had a past histrory of Kimura's disease, asthma, and allergic rhinitis, Histologic examination revealed panniculitls showing massive eosinophilic infiltration. The dermis showed eosinopbilic infilreatiom without flame figyres. The patient responded well to oral conrticosteroids. This patient did not fit the diagnosis of eosinoplilic pannicylitis, eosinophilic cellylitis, hypereosinophilic syndrome or eosinophilic vascylitis.

2.Echocardiographic Diastolic Left Atrial Emptying Index in Hypertensive Patients.
Korean Circulation Journal 1984;14(1):95-102
M-mode echocardiography has been demonstrated to be a sensitive indicator of the sequential changes occurring in the heart in systemic arterial hypertension. The changes in function as well as anatomic features have been recorded. Previous analysis has focused on the anatomy and systolic function of the left ventricle, analysed in hypertensive heart disease. 13 normal subjects(Group I), 14 hypertensive patients without evidence of cardiac involvement(Group II) and 13 hypertensive patients with echocardiographic evidence of left ventricular hypertrophy(Group III) were compared using M-mode echocardiographic data and clinical. findings. The results are as follows : 1) Mean age are; Group I : 41 years(19-62), Group II : 49 years(25-67) and Group III : 53 years(30-83). There are no significant age difference between Group I and II. Sex ratio are 4:9, 8:6 and 7:6 respectively. 2) Mean arterial pressure are; Group I : 98+/-5mmHg, Group II : 126+/-7 mmHg and Group III : 131+/-101mmHg. 3) Left ventricular posterior wall thickness are; Group I : 0.87+/-0.12cm, Group II : 0.89+/-0.12cm and Group III : 1.32+/-0.18cm(p>0.05 in I vs II). 4) Left atrial dimension are; Group I : 2.77+/-0.68cm, Group II : 2.96+/-0.44cm and Group III: 3.12+/-0.60cm. 5) Left ventricular mass arel Group I : 194+/-51gm, Group II : 192+/-51gm and Group III : 318+/-77gm(p>0.05 in I vs II, p<0.001 in I vs II and II vs III). 6) Ejection fraction are; Group I : 0.57+/-0.09, Group II : 0.60+/-0.01 and Group III : 0.52+/-0.01)p>0.05). 7) Mitral valve EF solpe are; Group I : 113.70+/-23.26mm/sec, Group II : 81.14+/-17.22mm/sec and Group III : 69.92+/-22.70mm/sec(p<0.05 in I vs II, p<0.001 in I vs III and II vs III). 8) AEI are; Group I : 0.70+/-0.04, Group II : 0.56+/-0.07 and Group III: 0.48+/-0.07)p<0.001 in I vs II, I vs III and II vs III). From the above results, the atrial emptying index seems to be an early indicator of abnormalities of left ventricular diastolic compliance in hypertensive patients.

The use of a pneumatic tourniquet is potentially associated with injury to underlying muscles, vessels, and nerves if excessive pressure occurs beneath the toumiquet. In order to minimize the risk of soft tissue injury, the lowest tourniquet pressure that maintains a bloodless operative field should be used. A clinical study was undertaken to evaluate the pneumatic tourniquet setting required for adequate hemostasis in upper extremity surgery. From March to September in 1984, the subcutaneous soft tissue pressure of the 20 upper extremities beneath a pneumatic toumiquet in the arm were measured directly and the following results were obtained. 1. The underlying subcutaneous soft tissue pressure was not affected by adult, age, arm circumference, and blood pressure of normal range. 2. The underlying subcutaneous soft tissue pressure showed direct correlation with the tourniquet pressure respectively. 3. A tourniquet preasure of more than 250 mmHg was not rarely required in a normotensive individual.

BACKGROUND: Recently the percutaneous transradial approach for coronary angiography, transluminal coronary angioplasty or coronary stention were reported but there was no report in Korea. So we tested the safety and efficacy of the transradial appreach for coronary angiography in Korean. METHODS: Eleven patients(male 9, female 2, mean age 59.3 yeal old)with chest pain underwent percutaneous transradial coronary angiography with 5 french multipurpose catheter. We evaluated clinical efficacy and observed complication of percutaneous transradial coronary angiography by physical examination and DOpple ultrasonography of puncture site of radial artery. RESULTS: Right coronary angiography and left ventriculography were performed successfully in all cases, but left coronary angiogrphy was failed in three cases. In another three cases, the patient complained of arm pain which was aggravated during manipulation of the catheter. After the procedure, it took 10.3 minutes to stop the bleeding at the puncture site, Clinically significant complications were not observed after the procedure. The patients were not restricted to bed at all since the completion of the procedure. CONCLUSION: In our limited dexperience, percutaneous transradial coronary angiography could be performend on the outpatient basis without significant complications.

All ceramic restorations have had a more limited life expectancy than metal ceramic crowns because of their lower strength. The relatively lower strength has limited the use of all-ceramic crowns to the areas where occlusal loads are lower. Therefore many researches have been done to increase the strength of all-ceramic crowns. IPS Empress 2 is a new type of lithium disilicate glass-ceramic with enhanced physical characteristics which has been in use clinically since 1998. Previous researches reported that the flexural strength of all-ceramic material was greater than 300MPa, and all-ceramic crowns can be used in staining or layering technique. The objective of this study was to investigate the influence of the thickness of IPS Empress 2 ceramic on fracture strength. Both staining technique and layering technique was investigated. Vita VMK was used as control. For all three groups, five specimens each of 0.8mm, 1.0mm, 1.4mm, 1.8mm, and 2.2mm thickness (a total of 75 specimens) were prepared. Control group: Vita VMK Porcelain specimens were prepared with dentine ceramic and liquid glazing was done. Group I: IPS Empress 2 were prepared with staining technique and stained twice and glazed once. Group II : IPS Empress 2 were prepared with layering technique and glazed after wash firing. The thickness and diameter of the specimen were measured and controlled after specimen preparation. Biaxial Flexure Test (ASTM Standard F394-78) was adopted as this test method produces results least affected by the edge condition of the specimens. Fracture strength was measured with Instron Universal Testing Machine. Conclusions are as follow : 1. The fracture strength was increase in order of control group, test group I, test group II. 2. Fracture strength of the group I(Empress 2 Staining) was 65.54 N in 0.8mm, 155.2 N in 1.0mm, 233.5 N in 1.44mm, 434.5 N in 1.8mm, and 600.1 N in 2.2mm. 3. Fracture strength of the group II (Empress 2 Layering) was 190.0 N in 0.8mm, 283.5 N in 1.0mm, 437.2 N in 1.4mm, 732.0 N in 1.8mm, and 1115.0 N in 2.2mm. 4. No statistical difference was found in flexural strengths according to thickness in a specified group(p>0.05).
