Catatracts are an infrequent but well-known complication of electrical injury, remains poorly understood. We report two cases of electric cataract with maculopathy experienced recently. The first case was a 58-year-old man who had exposed to 22000 voltage current and sustained third degree, 15% burn. 54th day after burn, the lenticular changes showed total opacity of both eyes and the intraocular pressure of left eye was 28 mmHg. 65th day after burn, extracapsular cataract extraction with posterior chamber lens implantation on left eye was performed. After the operation, naked vision was 1.0, but hard exudates were showed in macular area. The second case was a 23-year-old man who had exposed to 54000 voltage current and sustained third degree, 20% burn. 82th day after burn, the lenticular changes showed moderate opacities in the anterior and posterior subcapsular area of both eyes. 137th day after burn, extracapsular cataract extraction with posterior chamber lens implantation on right eye was performed. The final corrected visual acuity was 0.5 on 7th week after the operation due to lamellar macular hole.

Sparganosis is a parasitic infestation which is manifested principally in the cats or dogs, but many human infestations have not been reported uncommonly. In Korea, the reported cases of human sparganosis are more than 20 cases till now Moreover the urogenital infestation of sparganosis is rarely observed. We have experienced one case of sparganosis in scrotum, which would often be confused with the sperm granuloma.

Acute orbital cellulitis is most commonly caused by sinusitis. This complication is based on the anatomy of sinuses, orbit, and their venous connections. We have experienced a case of acute orbital cellulitis combined Subdural abscess due to maxillay sinusitis in a 14-year-old girl. Rapid Surgical drainage in the both upper lid and forehead and craniectomy resulted in complete recovery.

The pathology of Legg-Calve-Perthes disease be can described as a vascular distrubance leading to necrosis andsubsequent revascularization of the femoral epiphyseal ossification center. The regional distribution ofbone-seeking radiopharmaceuticals in the skeleton can depend on a number of factors, but bone blood flow is amajor phsiological determinant of regional skeletal uptake of Tc-99m polyphosphate and bone imaging may thus beused for the detection of areas with both decreased and increased vascular supply. The authors analyzed thescintigraphic findings of 14 cases of Legg-Calve-Perthes disease at Kyung Hee University Hospital from Mar, '81 toOct. '82. The resuls were as follows; 1. Scintigraphy revealed area of absent radioactivity in 14 cases; lateral2/3 portion of the femoral epiphyseal ossification center was involved in 9 cases among 14 cases, and alsoincreased radioactivity in epiphyseal ossification center, epiphyseal plate, or poximal metaphysis of femur wereassociated in 7 cases. 2. Three cases had radiographically normal hip, whereas scintigraphy revealed distinctlyabsent radioactivity in femoral epiphyseal ossification center. 3. Magnification of hip imaging using a pinholecollimator provided good definition of presence and extent of pathologic defect or uptake in epiphysealossification center, epiphyseal plate, and metaphysis. Bone imaging provided earlier and more accurate informationconcering the extent of the necrotic and revascularization process of Legg-Calv-Perthes disease than theradiographs alone.

The patient with an anterior open bite has one of the most difficult orthodontic problem to correct Previous studies have yielded different conclusions as to exactly where the morphologic problems associated with vertical dysplasia- high angle cases are located. In order to identify the cephalometric features of high angle cases and highlight the measurements that characterize high angle cases, 109 pretreatment cephalograms, 35 high angle, 37 average angle, and 37 low angle cases, were analyzed and compared statistically. As the mandibular plane was steeper, the anterior facial height, especially lower anterior facial height, became greater, and the posterior facial height became smaller. All the dentoalveolar vertical dimensions, especially in upper, increased. Arid all the skeletal angular measurements increased. Especially Lower gonial angle had most positive correlation to mandibular plane angle. Upper incisor was lingually inclined, and lower incisor was labially inclined in high angle cases.

Secondary ischemic necrosis of femoral head due to loss of blood supply following to femoral neck fracture is well known. The regional distribution of bone.seeking radiopharmaceuricals in the skeleton can depend on a number of facto rs, but bone blood flow is a major physiological determinant of regional skeletal uptake of Tc-99m polyphosphate and bone imaging may thus be used for the evaluation of vascularity of the femoral head. The authors made a comparative study of scintigraphic findings and operative findings of 28 cases of femoral neck fracture treated at Kyung Hee University Hospital from April ′80 to May ′84. The results were as follows: 1. In 16 cases of proven avscular necrosis of femoral head, scintigraphy showed absent or decreased activity in 14 cases (87.5%), while radiography showed increased density in 10 cases (62.5%). 2. In 12 cases of proven vital femoral head, scintigraphy showed increased activity in 9 cases (75%) and radiography showed decreased density in 9 cases (75%). 3. 99mTc-MDP scintigraphy was an excellent and useful method for assessing bone vitality of femoral head.

We evaluated MR imaging of spondylolytic spondylolisthesis degenerative spondylolisthesis and retrolisthesis in 14, 9 and 20 patients respectively. Sagittal and axial spin echo and gradient echo images were obtained with 25-30cm FOV and 5mm/0.5mm thickness/gap by using spine surface coil. Sagittal images showed defects of pars interarticularis just inside of the pedicles of spines in all the cases of spondylolytic spondylolisthesis with relatively variable signal intensity. Displaced vertebrae were commonly observed at L5 (8/14) in spondylolytic spondylolisthesis, at L4 (5/9) in degenerative spondylolisthesis and at variable locations in retrolisthesis. The mean length of displacement of vertebrae in spondylolytic spondylolisthesis was about 7mm and less displacement was onserved in degenerative spondylolisthesis and retrolisthesis. Seven, four and six cases of pseudobulging of disk at displaced level were observed in cases of spondylolytic spondylolisthesis, degenerative spondylolisthesis and retrolisthesis respectively. Seven, five and 14 cases of true disk lesions were onserved in cases of spondylolytic spondylolisthesis, degenertive spondylolisthesis and retrolisthesis respectively. Grade II neural foraminal stenoses (obliteration of one half epidural fat of neural foramen) were commonly (8/14) seen in spondylolytic spondylolisthesis, however the other two types showed less severe neural foraminal stenosis. In conclusion, MR imaging is a highly accurate method for the diagnosis and evaluation of spondylolisthesis and associated lesions of spine and disks.
