The anatomic and physiologic changes of the anopthalmic orbit affect cosmetic appearance of the patient and function of the socket and the prosthesis. During the past three years, the authors studied 13 cases of dermis-fat graft and 27 cases of posterior Tenon's capsule suturing with a plastic implant, and compared the post'operative effects of the two procedures. Dermis-fat graft produced good fornix formation with no remarkable fat atrophy after both primary and secondary proceddure. Posterior Tenon's capsule suture technique showes good effect to keep implant from migration or extrusion. Size of the plastic implant and fixation of the extraocular muscles were important factors also for good cosmesis and implant motility. There revealed no significant difference between the two procedures in EOM motility, enophthalmos, deep superior sulcus deformity, implant migration or prolapse etc.

Fifty-four marginal rotation procedures for cicatrical entropion and marginal entropion were performed in twenty-eight patients (8 males, 20 females). The age ranged from 4 to 74 years old (meant 51.1 years old). After the follow up periods of 6 to 48 months, excellent correction of the eyelid margin and good cosmetic appearance were noticed in most cases, but nine cases combined with severe trichiasis showed recurred trichiasis requiring reoperation.

The utilization of CT-guided fine needle aspiration biopsy of bone has been the subject of considerable interest, since the introduction of the CT scanning. The CT-guided needle biopsy of 11 consecutive patients with avariety of "Etiology Unknown Spinal Disorders" resulted in a 100% yield of positive tissue diagnosis without significant complicaitons. The main advantage of CT guidance is the continuous direct observation of the needletip position in relation to the target volume, the more precise sampling from smaller and deeper lesion is another advantage. We are confident that localization of pathology by CT is the most accurate method for perform ingbiopses, and thus replaces the conventional ways of approaches and this could be utilized on the other organbiopsy in the future.

Teratocarcinoma is a form of mixed germ cell tumor composed of a mixture of teratoma and embryonal carcinoma. It is rarely found in the brain, but when present it is most commonly found in the pineal region. We investigated a case of primary teratocarcinoma in the pineal region. The patient was a 10 year old boy who had suffered from a bitemporal headache for one month. Brain CT and MRI revealed a rather well defined ovoid heterogenous mass in the pineal gland region, measuring 4.3 x 3.8 x 3.0 cm in size. Microscopically the tumor contained areas of immature teratoma and embryonal carcinoma. Immunohistochemical staining revealed positive reactions for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen, and alpha-fetoprotein in the embryonal carcinoma component.

The symmetrical peripheral gangrene syndrome consists of sudden onset of symmetrical gangrene of the fingers, toes and more raely, the nose, upper lip, ear lobes, or genitalia. There is no evidence of occulusion of large vessels or vasculitis. We experienced a case of symmetrical peripheral gangrene developed in fingers and toes with disseminated intravascular coagulation in 20 day-old permature infant with sepsis by Enterobacter aerogenes. Thereafter, we presented a case with a brief review of the related literatures.

Based on the genetic homology between mouse chromosome 16 and human chromosome 21, experimentally induced trisomy 16 mouse has been considered to serve as a suitable model for human Down syndrome. Mice with trisomy 16 express several phenotypic characteristics of human trisomy 21 syndrome; i.e., intrauterine growth retardation, anarsarca, congenital heart disease, brain abnormality, etc. To elucidate morphogenesis of characteristic craniofacial malformation in human Down syndrome, we studied trisomy 16 mouse fetuses that were produced by crossing karyotypically normal C57BL/6 female ice with males carrying the two Robertsonian translocation chromosome Rb(16.17)/Rb(11.16). We examined a series of trisomy 16 conecptuses and their normal littermate controls from day 14 to day 18 of gestation by gross observation and serial microscopic sections. In addition to smaller size and generalized edema, we observed variable, but definite delay in brain and craniofacial development in trisomy 16 mice. The brain revealed less stratified telencephalon, underdeveloped thalamus and hypothalmus with relatively wide third ventricle, and small rhombencephalon. Craniofacial underdevelopment was characterized by persistent open eye, cochlea with fewer turns, delayed closure of the palate, more simple nasal cavity, etc. The tongue was shorter and convex upward, that were especially prominent at 14 days of gestation. The convex tongue and underdeveloped brain made the cranial base convex upward, and the angle between the cranial base an vertebral axis more obtuse. Small head with increase cephalic index and midfacial hypoplasia appeared to account for brain underdevelopment.

Congenital lipoid adrenal hyperplasia, the most severe form of congenital adrenal hyperplasia, is caused by mutations in the steroidogenic acute regulatory protien (StAR). It is characterized by failure of synthesis of all three classes of adrenal steroids and massive accumulation of lipids and cholesterol in the adrenal cortex. The computed tomography (CT) unequivocally delineated massively enlarged adrenal glands of fat-tissue attenuation, enabling early diagnosis and replacement therapy. We report a case of congenital lipoid adrenal hyperplasia, in which CT established that lipoid deposition at the adrenal cortex disappeared after the adrenal hormone replacement therapy.

A Tc-99m sulfur colloid hepatic scintigraphy is often the first imaging modality empolyed in the evaluation ofthe patient with suspected liver disease,since the hepatic scintigraphy is not only highly sensitive, low expenseand easy of performance but also provides both structural and functional information of the liver. The authoranlayzed the scintigraphic findings in 304 patient proven various hepatic disease and 58 normal liver, and alsoretrospectively analyzed the result of hepatic scintigraphy and ultlrasonography of the liver in 117 patients. Theresults were as follows; 1. The overall sensitivity and specificity of hepatic scintigraphy in the liver diseaseis 91% and 67%, respectively. 2. On the evaluation of the diffuse parenchymal parenchymal disease of liver, thescintigiraphy was found to be highly sensitive (88%) and also specific image patterns were found in cirrhosis. 3.The hepatic scintigraphy was highly sensitive (92%) in the detection of the focal lesions of liver. 4. Theultrasonography was capable of differentiating solid and cystic masses which were detected on scintigraphy, whilescintigraphy was more sensitive in detection of hepatocellular disease. 5. Tc-99m sulfur colloid imaging reminedthe preferred inital screening method in patients with suspected liver disease, while ultrasonography should bedone for those patients with prior suspicious findings.
