A case of aneurysmal bone cyst is reported in a 23 years old male, who complained of pain and tenderness on the right lateral aspect of thigh, This case had been treated with radical curettage and autogenous bone graft, but eight months later the radiological evidence of recurrence was present. So he was reoperated and he has been recovered relatively gradually, Roensgenograms of 7 montbs duration after reoperation showed abundent new bone formtion and no evidence of recurrence.

Ewing's Sarcoma is a rapidly growing malignant neoplasm that arises from primitive cells of the bone marrow in young persons. This case, a seventeen year-old male, complained of pain and swelling on the both knee. He had been treated under the impression of osteomyelitis at several local clinics. Clinically, malaise and high fever were continued during admission period. Microspically it was confirmed as Ewing's Sarcoma and then he was discharged. Presently he is under the radiation therapy.

We investigated the effect of 2% dorzolamide and 0.12% UF-021 on intraocular pressure and peripapillary and optic nerve head microcirclation with Heidelberg Retina Flowmeter. The 40 eyes of 40 normal subjects were divided 2 groups. 2% Borzolamide and 0.12% UF-021 were instilled in each group. The IOP and microcirculation of peripillary retina and optic nerve head were measured before and 90min, 4, 8, 12, 24 hours after instillation. The IOP was decreased at 90 minutes, 4, 8 hours after instillation of 2% dorzolamide and maximal reduction of IOP was observed at 90 minutes (P<0.05). The IOP was decreased at 90min, 4, 8, 12 hours after instillation of 0.12% UF-021 and maximal reduction of IOP was observed at 4 hours(P<0.05). But, there was no statistically significant changes of microciculation in both groups(P>0.05). We suggest that 2% dorzolamide and 0.12% UF-021 reduce the IOP, but do not alter the mictocirculation of peripapillary retina and optic nerve head.

In the real-time two-dimensional Doppler flow mapping(2DD) system, Doppler signals are processed using auto-correlation technique, so that the direction, velocity and turbulence of the intracardiac blood flow are displayed by coloration on the B mode image of the heart in real time. Aortic regurgitant flow is imaged as a mosaic jet spurting out from the aortic valve orifice to cardiac chamber. Dynamic features in the direction and extent of regurgitant flow and the site of regurgitation on the aortic valve orifice are readily obtained. Feasibility of the 2DD system in the assesment of aortic regurgitation was examined in 30 cases documented by angiography. In 30 cases, there were 20 cases with aortic regurgitation(AR) aged 16 to 57 years(mean 34) and 10 cases without AR aged 17 to 39 years(mean 30). The underlying disorders of AR were rheumatic in 15 cases, bicuspid aortic valve in 1, ventricular septal defect in 1, aortitis in 1, Marfan's syndrome in 1 and unknown in 1. The results are as follows : 1) In 19 out of 20 cases with AR the 2DD showed regurgitant jet spurting out from valve orifice(sensitivity=95%). One case missed by the 2DD had 1+AR. None of the 10 cases who had no AR manifested the evidence of AR on the 2DD(specificity=100%). 2) There was an excellent positive correlation between the maximal jet length of regurgitant flow on the 2DD and angiographic severity of regurgitation(r=0.998, p<0.001). The maximal jet length was less than 3cm for cases with 1+, 3-4.9cm for 2+, 5-5.9cm for 3+, and 6cm or more for 4+AR. 3) In 19 out of 20 cases with AR, the 2DD identifed the anatomic valvular site of regurgitation(sensitivity=95%, specificity=100%). 4) The regurgitant aortic valvular area was measured as 0.6cm2 or less in all of 12 cases with 2+ or less AR, while 0.9cm2 or more in 6 out of 7 cases with 3+or more AR. Thus, a less or greater than 0.8cm2 regurgitant aortic valvular area provides to discriminate between mild(< or = 2+) and severe(> or = 3+) AR. 5) In all 8 cases with fluttering of anterior mitral leaflet and 8 out of 9 cases with fluttering of interventricular septum, a regurgitant jet impinged on them. The results of this investigation indicate that the 2DD system is a very useful and unique noninvasive technique in the detection, estimation of severity and spatial orientation of AR.

he Magnetic. resonance imaging has been used widely to evaluate the disk position without any interruption of the TMJ structures, and the dynamic MRI presenting computed serial imaging or the video-recorded simulation images is thought to be very effective to evaluate the disk position under function. This is to study the correlation between the clinical diagnosis and the findings of dynamic MRI for diagnosis of internal derangement of the 7 patients were examined clinically, and the movement of TMJ meniscus was reviewed in the dynamic MRI. MRI was very reliable to diagnose the amount of anterior displacement of articular disc, the structural abnormality of temporomandibular joint, the cause of functional limitation, and to differentiate the muscle related pain & dysfunction.

Edwards syndrome is first introduced by Edwards and characterized by facial anomalies, multiple cardiovascular, gastrointestinal, urogenital, and skeletal malformations. It results from triplication of part or all of chromosome 18 in some or all of the patient's cells. It has an incidence of 1 in 4,500 live births or less and short life expectancy. Recently we experienced a case of 3-day-old female new born infant with this syndrome. Post mortem examination showed progeric face with prominent occiput, large flabby ears, microphthalmia, and micrognathia, bilateral clenched hands with flexion contraction of middle fingers, and bilateral rockerbottom feet. Internal examination revealed horseshoe kidney, esophageal atresia with tracheoesophageal fistula, two accessory spleens, and multiple cardiac anomalies. A trisomy 18 was confirmed by the cytogenetic study.

BACKGROUND: Recentliy copper vapor laser(CVL) has been applied with encouraging results in the treatment of port wine stain. The CVL emits yellow light(578nm) in a sequence of about 10,000 to 15,000 pulses/second(10-15kHz) with a pulse duration of 15-50 cases. One of the basic methods of evaluationg the effects of laser lights is to study histologic changes after laser irradiation. OBJECTIVE: The effects of power output and energy density on the histologic change of guinea pig skin following CVL irradiation was evaluted to suggest a way of deciding parameters of CVL to achieve the best clinical results. METHODS: After setting the power output for one of 0.8W, 1.6W and 2.4W, the laser was irradiated with an energy density of 10, 12, 14, 16, 18, 20J/cm. A biopsy was done 15 minutes after irradiation and the biopsy specimens was stained with H&E and NBTC histocberr ical method. RESULTS: 1. At the power of 0.8W, specimens irradiated with an energy density above 14J/cm showed diffuse nonspecific coagulation necrosis of the epidermis and upper dermis. 2. At the power of 1.6W, specimens irradiated with energy density of 14, 16J/cm showed coagulation necrosis of dermal vessel and perivascular collagen. With energe density of 18, 20J/cm, diffuse nonspecific coagulat,ion necrosis of epidermis and upper dermis were observed. 3. At the power of 2.4W, specimens irradiated with an anergy density of 12, 14, 16, 18J/cm showed coagulation necrosis of the dermal vessel and perivascular collagen. With an energy density of 20J/cm, diffuse nonspecific coagulation necrosis of the epidermis and upper dermis was observed. CONCLUSIONS : With the above results it was found that t,he higher power output of CVL enlarged the range of energy density confining thermal damage to the dermal v-ssels and perivascular collagen. Additionally the higher power raised the upper limit of energy density with which t,he epidermis was viable.
