In 1951, Leborgen pointed out the special diagnostic importance of punctate calcifications in the diagnosis of breast cancer by mammography. Calcifications within the breast may occure in both malignant and benign diseases, the characteristic findings have been reported subsequently by many other investigators. This study was done toreevalute the significance and diagnostic value of calcifications of female breast cancers. The clinical materals were 980 cases of those underwent mammography, and 76 cases of those histopathologically diagnosis was confirmed. Fine calcifications were radiologically found in 24 cases of these 76. A morphological analysis was made inregards to the relationship between the calcific particles and various mammary diseases. The results were asfollows; 1. The irregularly fine spiculate and punctate calcifications were found in 11 cases (45.8%) of cancergroup, and rather uniformly fine smooth calcifications were found in 14 out of 52 cases (26.9%) of benign conditions. 2. In cancer group, the calcifications were finely punctate or spiculate in shape and in numerable innumber with a tendency toward formation of densely packed clusters within and adjacent to the lesional areas. Nospiculate calcifications were observed in benign conditions. There were, however, no difference in either size ordensity of particles in both benign and malignant conditions. 3. These fine calcifications of the breast detectedby mammography seem to be a useful marker in localizing so small a lesion as not to be palpable and in obtaining proper biopsy specimen.

BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

The present study was undertaken to investigate the relationship between serum lipid and lipoprotein values and cerebrovascular accidents. Serum lipids and lipoproteins were measured in 130 cases of normal Korean, 49 patients with cerebrovascular accidents and 35 patients with uncomplicated essential hypertension. The results were summarized as follows; 1. The mean values of serum lipids in patients with cerebrovascular accidents were 148.3+/-75.3mg% for triglyceride, 189.6+/-37.4mg% for cholesterol, 132.5+/-55.2mg% for phospholipid and 548.8+/-106.3mg% for total lipid. 2. The mean values of serum lipoproteins in patients with cerebrovascular accidents were 255.3+/-81.6mg% for beta-lipoprotein, 118.3+/-73.7mg% for pre-beta-lipoprotein and 183.6+/-65.5mg% for alpha-lipoprotein. 3. There were no significant differences of sex and age in the mean values of serum lipids and lipoproteins in patients with cerebrovascular accidents. 4. In general the mean concentrations of serum lipids and lipoproteins, except phospholipid and alpha-lipoprotein, in patients with cerebrovascular accidents and hypertension were significantly elevated than in normal control subjects. 5. There were no significant differences in serum lipid and lipoprotein values between various types of cerebrocasculr accidents. 6. The change of serum lipid and lipoprotein values had a decreasing tendency till one month after onset, thereafter the values became similar to to\hose of early period of illness. 7. The incidence of hyperlipoproteinemia in patients with cerebrovascular accidents was 64%, and the most frequent type of hyperlipoproteinemia was Type IIa, as the frequency decreased in the order of Type IV, Type IIb and Type III.

Statistical observation was made on 2,639 cases with heart disease which has been seen in the Deparment of Internal Medicine, National Medical Center, in Korea, during the past 15 years ranging from January 1959 to December 1973. The results were as follows; 1. During the last 15 years, 2,639 cases with heart disease were observed, which represents about 12.9% of total 20,434 medical In-patients, and variable incidence for the consecutive years was noted. 2. The disease occurred most frequently in group aged under thirty and its incidence decreased in the fifth and sixth decades. 3. The incidence in male was 49.8% and in female 50.2%, the ratio of which was almost same. 4. The most common etiologic form of heart disease was hypertensive heart disease which occurred in 43.2% of all cardiac patients, corresponding to 5.57% of all In-patients. The incidence was most frequent in the sixth decade and decreased in the fifth and fourth decades with the male preponderance. 5. The second common heart disease was rheumatic heart disease, 31.6% of all cardiac patients, corresponding to 4.08% of all In-patients. It affected the mitral valve in most of the cases, whereas involvement of the aortic valve was rare. 6. Coronary heart disease, the third common heart disease, occurred in 5.1% of all cardiac patients, and most frequently in sixth and seventh decades. it affected male 2.5 times more frequently than female. 7. Postpartum heart failure and beriberi heart disease showed 3.8% and 3.1% respectively. They occurred more frequently in younger female, but the frequency was much decreased recently. 8. Pericarditis occured in 2.6% of all cardiac patients and tuberculosis was still a common cause of pericarditis. 9. Congenital heart disease was seen in 1.7% of the cases and patent ductus arteriosus, tetralogy of Fallot, atrial septal defect and ventricular septal defect occupied 76% of all congenital heart disease. 10. Cor pulmonale was present in 1.6%, arrhythmia 1.3%, cardiomyopathy 1.3%, thyroid heart disease 0.8%, endocarditis 0.7% and syphilitic heart disease 0.2%.

Local deposition of antibiotics has become increasing popular in the management of open fractures or osteomyelitis, and several substances have been employed as the vehicle for delivery. Although the elution characteristics of some substances have been documented, a comparative study of the characteristics of the commonly used substances were performed in order to establish the clinical indications for particular vehicles. Carriers were prepared, which were human iliac cancellous bone, bovine cancellous bone matrix(Lubboc?), absorbable gelatin sponge(Gelfoam?), fibrin glue(Beriplast? P) and polymethylmethacrylate(CMW?) for elution characteristics of vancomycin. The each carriers were immersed on the 20 ml of PBS and then obtained the samples for analysis of concentration of vancomycin at first, second, third, fourth, fifth, sixth, fourteenth, twenty-first, twenty-eighth day after immersion. The assay technique was fluorescent polarization immunoassay(Abbott, Dallas, Texas, U.S.A.). Nearly 50% of vancomycin was released from human iliac cancellous bone, Lubboc? and fibrin glue during the first 3 days, and negligible after first week. Gelatin sponge produced high local concentration of vancomycin during the first week. PMMA eluted the only 6% of vancomycin during the first day and trace amount detected as long as 4 weeks. There are significant statistical difference among carriers at second and fourth week(ANOVA test, P < 0.05). The authors considered that human iliac cancellous bone, Lubboc? ,Gelfoam? and fibrin glue may be best employed when brief antibiotic coverage is required, whereas PMMA may be better suited for long-term coverage.

Although there are various methods of operative treatment for hony mallet finger, the operative technique is not so easy and complications such as joint stiffness, sott tissue prohlems, infection, change of nail shape and arthrosis are common. The authors performed operations for 26 cases of hony mallet fingers, fixing the hony frapment by Kirschner wire, pull-out wire suture and miniscrew respectively, from Jan. l988 to Jun. l996. The results were as follows. l. According to Niechajev's classification. there were 3 cases of type B, 7 cases of type C, l4 cases of type D, and 2 cases of type E. And 11 cases were accompanied hy crushing injury. 2. Involved fingers were third finger in 11cases, fit'th finger in 7 cases, fourth finger in 5 cases, second finger in 2 cases. and thumb in I case. 3. The hony mallet finger was caused hy occupational injury in l6 cases, direct blow in 7 cases and sports injury in 3 cases. 4. The fractured fragment was fixed hy Kirschner wire in 9 cases, by pull-out suture in 9 cases and by miniscrew in 8 cases. 5. The results were evaluated hy Kanies scale. Sixteen cases had satisfactory results. Seven cases (87.5%) were satisfactory in miniscrew fixations. 5 cascs (55.6%) in pull-out wire suture methocls and 2 cases (22.2%) in Kirschner wire tixations. 6. The complications were joint incongruity in 4 cases, dorsal prominece in 6 cases, painful limitation of motion in 2 cases which were treated by arthrodesis, pin site infection in 2 cases and hreakage of wire suture in 1 case. 7. The miniscrew fixation offered relatively firm fixation, low complication rate, and good results. so it can be considered as one of the good methods of treatment for hony mallet finger.
