Bone marrow pressure is neither arterial pressure nor venous pressure of extremity, that is thought the precapillary pressure of bone. It is different between long bone and flat bone, and is also different in various site of the bone. Author measured bone marrow pressure of 84 normal femoral heads of Korean adults for basic data of early diagnosis of avascular necrosis of femoral head. The results are followings : 1. The baseline bone marrow pressure of Korean healthy adults is average 22.5 ±7.2mmHg. 2. The most significant change of bone marrow pressure in stress test is observed at 5 min. after injection of 5cc normal saline. 3. The increase of bone marrow pressure at 5 min. after stress test was average 7.4 ±4.4 mmHg. 4. Sex and age factors do not influence bone marrow pressure.

A total of 0.3ml of 100% sulfur hexafluoride(SF6) was injected into vitreous cavity with a single shot or two 0.15ml shots, and the time dependent intraocular pressure changes were compared. Intraocular pressure was monitored at 5 minute intervals for 60 minutes after injection. Immediately after a single shot injection, remarkable intraocular pressure elevation(85mmHg, mean)was observed, which returned, however, to normal level within 15 minutes. Intraocular pressure elevation was milder when a smaller bolus of gas(0.15ml)was separately injected twice. No re-elevation of intraocular pressure was noted with either method after the initial return to normal.

100% sulfur hexafluoride(SF6) was injected into the vitreous cavity of nonvitrectomized retinal detachment patients. A total of 0.5ml of gas was injected with a single shot in 3 eyes or two 0.25ml in 3 eyes without lowering of intraocular pressure. And in 3 eyes, single shot of 0.5ml of gas was used after lowering of intraocular pressure. The changes of intraocular pressure were monitored at 5 minute intervals for 60 minutes and at one hour intervals for 8 hours after injection. Marked elevation of intraocular pressure was noted in both single shot group, but the elevation of intraocular pressure of double shot group was much smaller. But in all groups, the intraocular pressures were returned to under 30mmHg within 20 minutes and no re-elevation of intraocular pressure was noted in all cases after initial return to normal. In a case with two 0.3ml shots, the highest pressure was 49mmHg and with 0.35ml shots, the highest pressure was 78mmHg. So the effect of SF6 on intraocular pressure seemed to be negligible so long as the injection volume was limited to 0.5ml or less in single shot; and 0.6ml in double shots.

We performed analysis of 79 childhood patients diagnosed as vitiligo and nevus depigmentosus in Tediatric Dermatologie Department of Seoul National University Hospital from March 1987 to September 1987. The results were as follows : 1. Of the 79 patients, 31 patients(39.2%) were vitiligo 21 patients(26.6% )were nevus depigmentosus and 27 patients(34.2%)were uncertain by cliniral diagnostic ctriteri.. 2. Viiligo began rarely in infancy(6.4% )and most appeared evenly in all childhood over 1 year old. Nevus clepigmentosus was present at birth in 57.1% of patients and was discovered within the first 6 months after birth in 42.9% of patients. 3. In vitiligo, most lesions were multiple. The most common site of involvement was the face, and there was this tendency of periorficial predisposition. In nevus ciepigmentosus, most lesions were solitary. The most, common aites of involvement were the lowed limbs and trunk, but there was no tendency of periorfcial presposition. 4. We found focal type of vitiligo in,51,6% of patients, vulgaris type in 32. 3 % acrofacial type in 9.6% and segmerital type in 6.5%. We also found isolated pattern of nevus clepigrnento us in 76.2% of patients, ciermatomal p<:ttern in 19.0ki and whorlec1 pattern in 4.8% The contrast enhiancement between the hypopigmented skin and nomal surrounding skin by Wood's light, examinatior reflected the epiclermal melanin pig merit, i. e., the more marked loss of pigmentation, the more accentuatian of the contrast The before, Wood's light examination without I:3OPA staining could help to ciiagnose the atisculte type of vitiligo showing eidermal melanocytes and nevu c.Iepigmeritosus.

PURPOSE: To evaluate the value of fast field echo(FE) technique in accesing temporOmandibular joint(TMJ) dynamics. MATERIALS AND METHODS: A series of 120 TMJ MRI examinations of 60 symptomatic patients was performed. The fast FE technique was used to provide dynamic images of the TMJs in various phase of mouth opening with a step-bite-block. RESULTS: Among 120 cases, there were 30 cases which were normal, 21 cases of anterior displacement with reduction, 66 cases of anterior displacement without reduction, 11 cases of deformity of menisci, 23 cases of bony deformity, and 3 cases of medial displacement. The menisci and condyles were clearly delineated and the motions of the menisci during jaw opening were well evaluated in both normal and pathologic conditions. CONCLUSION: The dynamic TMJ MRI scan using fast FE technique permits both fast scanning and study of joint dynamics as well as TMJ anatomy.

Febrile ulceronecrotic PLEVA is an unusually severe from of PLEVA, characterized by the sudden onset of diffuse ulceronecrotic eruption aasociated with high fever. A mild eruption precede the acute fulminating course, We observed a 13-year-old boy presenting the form of febrile ulceronecrotic PLEVA. The histologic features were those of PLEVA. He received the systemic corticosteroids with aupportive care. To recognize this disorder is important because of a possibly fatal outcome, So close attention and vigorous therapy are necessary.
