Acetabular fractures are usually caused by violent external force such as car clash and commonly accompany injuries of the other parts of the body. And there has been long controversy between conservative and operative treatments. A clinical analysis was performed on the 29 patients with acetabular fractures, who had been treated at seoul National University Hospital from 1973 to 1982, mainly focussed on the result of treatment. Followings are the summary of the result. 1. Conservative treatment was done in 52% and operative treatment in 48%. 2. Mean follow-up period was 1 year and 8 months. 3. The result of treatment was good or fair in 53% of conservative treatment group comparedto 71 in operative treatment group. 4. Primary total hip replacement was done in one case of bursting fracture combined with fracture of femur neck and the result was good. 5. Superior and bursting fractures showed the worst result(poor in 83%). 6. Degenerative arthritis with or without avascular necrosis was the most common complication (45 %) and it was more common in conservative treatment group (60 vs. 29%). 7. From above results it could be said that operative treatment in acetabular fractures, if carefully done with reasonable indications, would improve the result and decrease the rate of degenerative arthritis.

Ultrasongraphy is a safe, noninvasive examination which should be the first procedure in the workup of apatient with a definite or suspected pelvic masses. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass canbe used to subcategorized these masses into a more useful differential diagnosis. The results are as follows; 1.The most characteristic finding of uterine myoma was midly to mederately echogenic uterine enlargement (90.7%)with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterincontents(93%). 3. The most frequent finding of cystic teratoma was cystic mass with echogenic foci(48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancywere adnexal mass(comlex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid incul-de-sac, deveiation of uterus by adnexal mass, and psuedointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false-negative in 7.4%.

Vitiligo is a relatively common depigmentary disorder occurring in approximately 1-2% of the general population. All races are affected. Both sexes are likely to be affected equally; the female prevalence in some studies can probably be attributed to cosmetic reasons. It can occur and spread at any stage of life and is often associated with a positive family history. Up to 30 percent of patients have reported vitiligo in another family member. The lesion is characterized by discrete, pale-white macules, few or several in number, which tend to enlarge centrifugally over time. It is not contagious, nor is it a serious health problem. However, it can be troublesome in brown and black people as well as in white persons who tan deeply (skin phototype IV), and often leads to social embarrassment and psychological turmoil.

There are many options for the management of osteoarthritis of the knee joint. Recently, arthroscopic surgery has been added to the armamentorium of the treatment modalities in osteoarthritis of the knee which does not respond to conservative treatment. Among 74 arthroscopic pocedures(including partial menisectomy, removal of loose bodies, synovectomy, cartilage drilling and simple lavage) done for osteoarthritis of the knee, 68 patients studied at average 3.1 years after procedure and the results were as follows 1. Seventy-one percent of patients had at least 2.5 years or more relief of pain and symptoms. 2. Fifty-six percent were still good at follow-up of 3.1 years. 3. The best result were obtained after removal of loose bodies and resection of unstable flap tear of a meniscus in association with mild osteoarthritis. 4. The poor result were obtained in patients with severe degenerative changes of both femoral condyle, 5. The results were much better in the normally aligned knee compared with valgus knee.

Thirty-six patients (24 with oral cavity or oropharynx cancers and 12 larynx cancers) were prospectively examined with computed tomography (CT) to determine its value in staging the primary tumor and to compare with the clinical staging. The CT staging agreed with the clinical staging in 50% (12/24) of the oral cavity or oropharynx cancers and in 67% (8/12) of the larynx cancers. The CT upgraded the clinical staging in 29% (7/24) of the oral cavity or oropharynx tumors and in 33% (4/12) of the larynx cancers, whereas the CT downgraded the clinical staging in 21 % (5/24) of the oral cavity or oropharynx cancers. There is no downgrade on CT in larynx cancer. The post-surgical confirmation was not made in most of the cases. The possible causes of disagreement between the CT and the clinical staging, and the diagnostic value of the CT in evaluation of the primary tumor in oral cavity, oropharynx and larynx were discussed.

Eighty-eight patients who presented with a variety of head and neck symptoms were examined with intravenous oritraarterial digital subtraction angiography (IV or IA DSA), using the DSA equipment developed by Seoul NationalUniversity Hospital. A grading system was used to evaluate the ability of DSA to answer specific diagnsoticquestions. Diagnostic information without need of further study was obtained in 71% with IV DSA, in 86% withaortic arch DSA and in 81% with selective arterial DSA, showing a total of 79% of diagnostic accuracy with DSA. Itis concluded that IV DSA is useful in the evaluation of the cervical carotid and vertebral arterial disease, andpituitary mass lesion, while IA DSA is useful in the evaluation of the cervical carotid and vertebral arterialdisease, and pituitary mass lesion, while IA DSA is useful in the evaluation of most of the intracranial lesions,spinal arteriography and intra-arterial embolization. DSA is both an accurate and safe imaging modality in thestudy of head and neck diseases.

BACKGROUND: Vitiligo is an acquired disorder with destruction of melanocytes and is clinically characterized by depigmented patches of skin. The pathogenesis of vitiligo is still unclear, but melanocyte self destruction, neurohumoral factors, autoimmunity and inherent cellular defects have all been proposed as possible etiological factors. OBJECTIVE: The purpose of this study was to find out the differences in expression of HLA antigens among subtypes of vitiligo according to classification, onset and family history and then to disclose the pathogenesis of vitiligo in view of genetic and autoimmunological aspects. METHODS: We investigated HLA-A, B, C, DR in subgroups of 87 vitiligo patients according to type, onset, and family history. Results : 1. There were no HLA antigens with significantly increased frequency in vitiligo patients compared to the control group. 2. There was a significant increase in frequency of HLA-DRl2 in patients of non-segmental vitiligo with a family history ; an increase in frequency of HLA Cw2 in patients without a family history ; and a significant increase in frequency of HLA-DRl2 in all patients of non-segmental vitiligo compared to the control group.(p(c)<0.05). 3. The frequency of HLA-B63 was significantly increased in all patients of segmental vitiligo compared to the control group(p(c)<0.05), but there were no HLA antigens with significantly increased frequency in patients of subgroups of segmental vitiligo divided by the presence or absence of a family history of vitiligo. 4. The frequency of HLA-B54 was significantly increased in all vitiligo patients with a family history(p(c)0.05) but there were no HLA antigens with significantly increased frequency in all vitiligo patients without a family history. 5. There were no HLA antigens with significantly increased frequency in vitiligo patients subgrouped by age of onset (less or over 16 years) of disease. Conclusion : From the above results, we can assume that non-segmental vitiligo may have autoimmune mechanisms in the pathogenesis, as there was a significant increase in HLA-DRl2 in patients with non-segmental vitiligo.
