Most fractures of the proximal humerus are managed well to simple conservative treatment. But open reduction and interhal fixation of the fragment is definitely indicated in certain types of displaced fractures. Thirty eight cases of fractures of the proximal humerus which were treated at Inje Medical College from January 1980 to December 1985 were analyzed both clinically and radiologically accordingto Neer's classification and the following results were obtained. l. Among the 38 patients, the ratio of male and female was 2.2:1 and the highest incidence was in the fifth decades. 2. The main cause of fracture was traffic accident, 20 cases (52. 6%) and the the next one was falling from a height. 3. According to the classification of Neer, one part acture(52.6%) was the most common type. 4. The common associated injuries were fracture of the lower extremities and forearms. 5. Thirty two cases(84.2%) were treated by conservative treatment and six cases by operative treatment. 6. Thirty eight cases were followed form 6 months to 5 years and 6 months, average 14.3 months, and the results were analyzed according to Neers criteria and 26 cases (68. 6%) showed excellent results. 7. Two cases of limitation of shoulder motion were observed as a complication and one cases of paralysis of deltoid muscle by axillary nerve injury was observed. Excellent functional result could be obtained by a simple external support with early motion in a minimal displacement of proximal humeral fracture. Satisfactory functional result could be obtained by a open reduction and internal fixation with early motion in a severely displaced fracture. But long term immobilization of shoulder could have a poor functional result.

With the expending use of sublaminar segmental instrumentation, various complication, including paraplegia, paresis, dysesthesia and dural tears, have been reported. These findings suggest that the displacement of sublaminar wires toward the spinal eord during extraction followed by spinal cord damage. The cut surface of Luque sublaminar wire is sharp and has a barb and it may cause damage to the spinal cord. The cut end of Luque wire was inserted into the Intracath (a kind of angiocatheter) 16 gauge and pulled parallel to the lamina. And we found the Intracath followed by Lugue wire in the operating field. Lateral view of spine roentgenogram revealed that the radioopaque Intracath was passed under the lamina in 3 mm in depth. When the Luque wire is removed with inserting into the Intracath 16 gauge and pulled parallel to the lamina, the dura can be protected by the cut end of Luque wire.

In this study, radiographic evaluation was made using panoramic radiography and cross-sectional tomography of SCANORA in male and female adults in their 20 s on the relationship between the maxillary sinus floor and the apex of the maxillary molar, to test the accuracy and effectiveness of the cross-sectional tomography, and to use this information in the assessment of preop, and postop, root canal treatment, apical surgery, extraction and implantology. Forty-one adults with an average age of 24.4 years were studied panoramic radiography and cross-sectional tomography. In panoramic view and cross-sectional view, the position of the apices of maxillary molars were classified as separated, contacted, or protruded type; the general shape of the maxillary sinus floor was evaluated horizontally and vertically from cross-sectional tomography. The accuracy of each radiography was tested using maxilla from 5 fresh cadavers from the Anatomy Lab at Yonsei University Dental College, and panoramic view and cross-sectional tomography were taken in the same condition as with the patients. The results were as follows ; 1. Panoramic view and cross-sectional view were taken in the maxilla specimen, and the actual distance between the maxillary sinus floor and the tooth apices were measured in the specimen; the median values of the distance from the tooth apices to the maxillary sinus floor in the panoramic view, cross-sectional view and in the acrual maxilla specimen were 2.83mm, 4.51mm, and 4.15mm, respectively. In the cross-sectional view, the measured distance was close to the actual distance but in the panoramic view, the measured distance was far from the actual distance. 2. When the results of the panoramic view and cross-sectional view were compared, 40.5% of the results agreed with each other in the two radiographic methods and buccal roots of the 2nd molar were the closest to the maxillary sinus floor in the cross-sectional tomography. 3. In cross-sectional view, when the vertical relatioship of the maxillary sinus floor and maxillary roots was assessed, in 1st molars, type II (the sinus floor that extends down to the buccolingual furcation area) was predominant, while in 2nd molars, type I (the sinus floor located above the level connecting the buccal and lingual apices) was predominant. In the horizontal relationship, in 1st olars, type II (ths lowest floor of the maxillary sinus located in between the buccal and lingual roots) was predominant; in 2nd molars, type I (the lowest floor of the maxillary sinus located on the buccal side of the buccal roots) and type II appeared in similar frequency. In conclusion, the SCANORA cross-sectional tomography was more effective than the frequently used panoramic view, in that the relationship of the maxillary molars and maxillary sinus floor can be evaluated more accurately and the buccolingual cross-sectional view can also be observed. And maxillary sinus floor that was close to maxillary 2nd molar had tendency to be located on buccal side than that close to 1st molar. Therefore, cross-sectional tomography is an effective and accurate method to evaluate the position of the teeth in relation to the sinus floor preoperative and can be easily used to diagnose localized periapical lesions. Also the image quality obtained was quite satisfactory.

BACKGROUND: There has been no statistical study of dermatoses in the Ganganm area of Seoul which has been rapidly developing in the last 10 years. OBJECTIVE: We evaluated the recent distributions of dermatoses in the Gangam area of Seoul and compared them with the previous reports in Seoul and other provinces of Korea. METHODS: 47,015 new outpatients who visited the Yongdong Severance Hospital from 1983 to 1992 were analyzed statistically RESULTS: The study results are summarized as follows: 1. Among the 47,015 outpatients, the total number of number of male patients were 20,180(42.9%) and female patients 26,835(57.1%). 2. In age distribution, the most frequent age groups were the 3rd decade(21.3%), the lst decade(19.5%), and the 4th decade(19.2%) amounting to 60% of the total outpatients. 3. The most common 15 dermatoses were dermatophytosis, atopic dermatitis, urticaria, irritant contact dermatitis, acne vulgaris, allergic contact dermatitis, seborrheic dermatitis, other eczemas, warts, vitiligo, drug eruption, herpes zoster, psoriasis, bacterial infection, and syphilis. 4. Those dermatoses which showed an increasing tendency annually were seborrheic dermatitis, warts, vitiligo, and syphiiis. Dermatophytosis and bacterial infection showed a decreasing tendency. 5. Seasonal distribution showed that those diseases occurring most frequently during the summer were dermatophytosis, urticaria, allergic contact dermatitis, vitiligo, herpes zoster, and bacterial infection. The incidence of atopic dermatitis and psoriasis increased during the winter season. 6. In sexual distribution, acne, allergic contact dermatitis, and irritant contact dermatitis were more frequent in females, and the remainding common dermatoses did no show any difference. 7. In age distribution, atopic dermatitis and bacterial infection were most frequent in the lst decade. Urticaria, allergic contact dermatitis, acne, drung eruption, psoriasis, and syphilis were most frequent in the 3rd decade, with warts and vitiligo in the 2nd decade, and herpes zoster in the 6th decaded. 8. The distributions of dermotoses as disease groups were eczema(24.9%), urticaria-drug eruption (13.2%), dermatophytosis(10.7%), skin appendage disorder(10.1%), viral infection(10.1%), pigmentary disorders(4.5%), and papulosquamous diseases(4.0%) which constituted 78% of the total. 9. In patients dwelling in apartments, atopic dermatitis and molluscum contagiosumn showed a more frequent tendency in comparison to those living in house. 10. The most common 10 dermatoses among children were atopic dermatitis, urticaria, contact dermatitis, molluscum contagiosum, bacterial infection, dermatophytosis, vitiligo, other viral infections, and nevo-cellular nevi. On the other hand, the most common 10 dermatoses among the elderly were drmatophytosis, other eczemas, urticaria, herpes zoster, pruritus, contact dermatitis, drug eruption, lichen simplex chronicus, seborrheic dermatitis, and vitiligo. CONCLUSION: In contrast to earlier published report from Seoul, the infectous dermatoses, especially parasitic infestation, showed a decreasing tendency. The distribution pattern of the skin diseases did not differ fro other provinces of Korea in general.

Eighteen cases of double outlet right ventricle were observed during past six years at the department of pediatrics, Seoul National University Hospital. 1. Therw were 13males and 5 females. Sex ratio showed male predominance with the ratio of 2, 6:1. 2. According to the Sondheimer's classification, 6 cases were in group l, none in group ll, 10cases in group lll and 2 cases in group lV. 3. Presenting symtoms and signs were cyanosis(18/18), dyspnea(17/18), growth retardtion(10/18), and cyanotic spell(6/18). 4. The range of hemoglonin concentration was 14 to 21 gm%(mean 18.2gm%). Simple chest X-ray showed cardiomegaly in 10 patients. On routine ECG examination, RVH were noted in all 18 cases. 5. In group l patients, mean oxygen saturation of the aorta was 74.5%, mean oxygen saturation of the pulmonary artery was 86.7%. But on group lll, the results were variable. And in guoup lV, oxygen saturation difference were negligible in both great arteries. 6. Pulmonic outflow obstruction were noted in 12 cases in which 8 cases were combined type. 7. Operation was done in 8 cases. Out of the 6 cases who were receive corrective surgery, 3 cases died of the right heart failure. 8. Associated anomalies were as follows : bilateral SVC in 6 cases, PDA in 5 cases, ASD in 4 cases and dextrocardia in 4 cases.
