PURPOSE: MRI is known to be an effective imaging modality of the aorta and its role is steadily increasing in the evaluation of acquired aortic diseases including aortic dissections and aortic aneurysms. However, differentiation of the aortic dissections with thrombosed false lumen from the aortic aneurysm with mural thrombus in MRI has not been easy. Therefore, the authors tried to find the characteristic MR featrses which would to differentiate the two diseases. MATERIALS AND METHODS: MR images of 6 patients with thrombosed aortic dissection and 7 patients with thrombosed aortic aneurysms were reviewed retrospectively and compared in regand to shape and extent of thrombus, dimension of aorta, and luminal flow signal. RESULTS: Thrombosed aortic dissections showed sharply demarcated crescent shaped aortic wall thickening of even thickness involving long segment of the aorta, whereas thrombosed aortic aneurysms showed irregular aortic wall thickening of uneven thickness localized in the short dilated segment of the aorta. Characteristically aortic aneurysm with mural thrombus showed eccentric intraluminal slow flow signal. In contrast to the signal void of the true lumen in aortic dissections, the residual lumen of the aortic aneurysm with mural thrombus revealed intraluminal signal due to slow flow. CONCLUSION: Familiarity to these MRI findings of thrombosed aortic dissections and aortic aneurysms may lead to the accurate differential diagnosis in majority of cases.

Trichoblastic fibroma is a benign trichogenic tumor that has both epithelial and mesenchymal components and exhibits partial follicular induction. We studied 4 cases of trichoblastic fibroma and reviewed their clinical and histologic features. Two tumors were present in the face. The remaining two were in the vulva and perianal area, respectively. The age of the patients ranged from 53 to 68 years, with an average age of 62. All were female. Histologically, the lesions showed a well circumscribed mass, located at dermo-subcutaneous junction in three patients and subcutaneous in one. They demonstrated mesenchymal induction evidenced by hair germ-like structure and perifollicular sheath. There was no connection between the tumor and epidermis. Differentiation toward hair structure led to the formation of the infundibulum through inner root sheath. Trichoblastic fibroma may be confused clinically and/or histologically with basal cell carcinoma. Identification of the mixed epithelial and mesenchymal components, and the absence of epidermal connection and cleft within the stroma are important in differentiating this benign neoplasm from basal cell carcinoma.

The anterior cruciate ligament(ACL) is one of the major stabilizers of knee motion. The ACL does not heal once torn, unlike many other biological tissues. Its absence can lead to severe joint instability which can lead to disruptions of secondary restraints around the knee and then progress to degenerative joint disease. Thus many authors advocate surgical intervention for a torn ACL in order to restore stability to the joint. Yet, there is still controversy as to best treatment for the ACL injuries. It is desirable to be considered for the patients age, the severity of the injury, and the future activity level of the patient to decide treatment. We analyzed thirty ACL acute injuries of twenty seven patients who had an ACL injury and treated surgically between Apr. 1986 and Dec. 1991 at St. Pauls Hospital. The results were as follows: 1. There were twenty five males and two females. The mean age was 33.4 years ranged, 15 to 52 years. 2. The anterior cruciate ligaments were torn at proximal portion in twenty two cases, at midportion and distal portion in four, respectively. 3. Two knees had isolated ACL injuries and twenty eight had combined injuries. 4. Twenty one out of twenty six cases treated with primary repair, and three out of four cases treated with reconstruction had good-excellent results.

Self expandable metallic stent is a good alternative of percutaneous transhepatic biliary drainage because it can eliminate numerous problems caused by external drainage catheter, such as tube dislodgement, bile leakage and psychotic problems. Authors analyzed initial results of self expandable metallic stents used in the patients with malignant biliary obstruction to evaluate the efficacy of the procedure and to find the technical problems in the procedure. Self expandable metallic stents were inserted in 14 patients: three with recurrent stomach cancer: there with gallbladder cancer: seven with Klatskin tumor: one with common duct cancer. Gianturco type stent was used in 9 cases ans Wallstent was used in 2 cases. In remaining three cases, both Z-stent and Wallstent were used in the same patient. The average period of follow up was 104 days (4-409). In 13 cases, the patency of the bile duct was restored by the stent (technical success: 92.9%). Occlusions of the stent were found in two cases, after two and 13 months, respectively. Causes of failure and stent occlusion were associated duodenal obstruction, tumor overgrowth and shortening of Wallstent. In remaining 11 patients, one patient was lost to follow up an 10 patients did not show recurrent jaundice until death or last follow up. There was no major complication related to the procedure. The insertion of self expandable metallic stent is a safe procedure and call eliminate major disadvantages of PTBD. Overstenting, overlapping land evaluation of associated GI tract obstruction is crucial for obtaining technical success and long-term patency.

Most proximal humeral fractures respond satisfactorily to simple conservative treatment, but operative treatment is recommended in cases where poor results are anticipated by prolonged immobilization, or because of severe displacement and comminution. We used a minimal internal fixation and tension band technique in severely displaced and comminuted cases to achieve firm fixation and avoid subacromial impingement. Passive range of motion of the involved shoulder began within the first postoperative day and active range of motion exercise was encouraged as soon as possible within the first postoperative week. Between February 1996 and November 1997, we operated using this technique on 15 patients ranging in age from 16 to 71 years (average 52). Follow-up averaged 13 months. During the follow-up period, all patients except one patient, had a active full range of motion on the affected limb. According to the evaluation on the 10 patients who had follow- up periods over 12 months by Hawkins rating scale of shoulder function, 6 patients had achieved a good result and 4 patients had achieved a fair result at the last follow up. In conclusion, tension band technique with minimal internal fixation could afford sufficient fracture stability to allow early, aggressive rehabilitation. As a method of internal fixation on a proximal humerus fracture, this technique may have particular advantages in elderly osteoporotic patients.

A case of transient neonatal diabetes mellitus combined with congenital adrenal hyperplasia(CAH) is described. A female infant was born by cesarean delivery due to fetal distress, she had sunken eyeball and anterior fontanelle, large protruded tongue and thin subcutaneous tissues. She had large clitoris and progressive pigmentation on whole body was observed since 10th day of birth. Hyperglycemia and glycosuria was noted at 3rd day of birth. Level of insulin and C-peptide was 3.0 mU/L and 0.35 ng/mL respectively. Serum ACTH was 870.4 pg/mL and 17-hydroxyprogesterone was increased to 20,000 ng/dL. Serum Na was 124 mEq/L, K 5.6 mEq/L. Abdominal MRI showed no abnormality. Chromosomal study showed 46,XX. Genetic analysis with polymorphic DNA markers for chromosome 6 showed paternal uniparental isodisomy at D6S276, D6S1704 and DNA analysis of CYP 21 gene showed mutation at P435S. She required insulin therapy for 8 months after birth. Hydrocortisone and florinef was needed for the control of CAH.

This study was designed for the facial reconstruction of Father Dae -Gun (Andrea) Kim, who is the first priest in Korea. The study was entrusted by Seoul great parish, Myeongdong Cathedral and was conducted during 15 months from September 1999. To reconstruct the face of Father Dae -Gun (Andrea) Kim, we used photographs and metric data of Father Dae -Gun (Andrea) Kim's skull, which was measured by Department of Anatomy, Catholic Medical College at 1971. Based on above data, we found a skull similar to Father Dae -Gun (Andrea) Kim, replicated it, and modified it to be consistent with that of Father Dae -Gun (Andrea) Kim measured at 1971. The face of Father Dae -Gun (Andrea) Kim was reconstructed on the modified replica of Father Dae -Gun (Andrea) Kim's skull using the forensic anthropological data about the average skin depth and the relationships of skull morphology to facial features of Korean. The average skin depth of Korean face was obtained from direct measurement of cadavers and indirect measurement of live Korean using ultrasonography. The result of facial reconstruction of Father Dae -Gun (Andrea) Kim was made as the bronze bust. The forensic anthropologic method such as facial reconstruction is one of the methods to identify unidentified -skull. This study is the first facial reconstruction on the base of Korean physical anthropological data and is thought to be helpful to the facial reconstruction for identification.
