Cardiovascular measurement on PA teleroentgenogram of the chest is simple, but very useful in the diagnosis,prognosis, and therapy of hypertensive patients. The authors have measured and calculated cardiothoracic ratio,Lt, to Rt. cardiac diameter ratio, and Lt, aortic knob width to thoracic diameter ration for evaluation of theeffect of blood pressure and age in hypertensive group. We used materials of 70mm fluorography of 255 hypertensivemen above 150/90mmHg chosen from national police hospital during Jan. from Aug. 1981. Their age ranged from 20 to50 yeras. The results were as follows. 1. Cardiomegaly (above 50 percents in cardiothoracic ration) ofhypertensive men is 26%. 2. The cardiothoracic ration increased progressively with blood pressure and age, butpooly correlated between cardiothoracic ration and age than blood pressure. 3. The Lt. to Rt. cardiac diameterration gave similar trend to the cardiothoracic ration. It indicates that hypertensive cardiac enlargement mainlydepned on Lt. Ventricular enlargement. 4. The Lt. aortic knob width to thoracic diameter ration increasedprogressively with blood pressure and age, and had linear correlationship with blood pressure and age. Therefore,prominence of aortic knob is the most significant finding in hypertensive cardiovascular disease.

In 1983, Nora et. al. reperted 35 cases of bizarre parosteal osteochodromatous proliferations of the hands and feet. All lesions occured on proximal phalanges, metatarsals, or metacarpals. The gross appearance was typically that of a small osteochondroma. Radiologically, the proliferations lacked both central continuity of the tumor with the underlying osseus medulla and flaring of the adjacent cortices. Histologically, the lesion exhibited marked proliferative activity, irregular bohy cartilaginous interface, and enlarged, bizarre, and binucleate chondrocyte. The authors experienced a case of bizarre parosteal osteochondromatous proliferation of the right foot in a 61 year-old female which arised from the proximal phalanges of second toe, hostologic and radiologic findings were consistent with the bizarre parosteal osteochondromatous proliferation. The mass was treated by excision, and neither recurrence, nor malignant change was observed up to one year follow-up period.

Longitudinal growth acceleration of the femoral shaft after fracture in children has been recognized since the late nineteenth century, Orthopaedic surgeons have attempted to compensate for the leg length discrepancy by allowing union to occur with some degree of shortening, but logitudinal overgrowth following fractures of the tibial shaft in children has been rarely studied. Thirty-one children, treated for fracture of the shaft of tibia, were studied prospectively to assess the consequent increase in longitudinal growth of the tibia. The material presented in this paper is the result of the study of thirty-one children with fractured tibia who were treated in the Department of Orthopaedic Surgery of Kangnam Sacred Heart Hospital of Hallym University, since 1986 October, the age of the child varied from 3 years to 13 years, these cases have been followed from 30 months to 40 months. We have made a radiologic study of fracture of the tibial shaft with a view to analysing the results according to a number of factors, including the sex and the type, site and degree of overriding of fracture, and method of treatment, and then the degree of overgrowth was compared with unaffected side. 1. The average tibial overgrowth following tibial shaft fracture is 7mm. 2. Growth of the femur was not affected by the tibial fracture.

PURPOSE: The purposes of this article are to identify CT findings distinguishing nasal polyps, that are the most common cause of the nasal polypiod lesions, from other nasal cavity masses and to identify differential points between benign and malignant masses of nasal cavity. MATERIALS AND METHODS: We classified 567 cases of pathologically proved nasal cavity masses into 4 different groups on CT according to the sites of origin and surrounding bone changes. RESULT: The nasal polyps were the most common cause of nasal cavity masses(515/567). Group I had a high diagnostic specificity for the nasal polyps (513/515, 99.6%) although inverted papilloma (8/522) and malignant melanoma(1/522) showed similar CT appearances. The representitive nasal mass of Group Ila was the inverted papilloma (15/24, 66.5% of the inverted papilloma). Group III pattern was seen in 3 cases of benign minor salivary gland tumor and 2 cases of pyogenic granuloma. Group IV suggested malignancy and thus was mostly observed in malignant tumors except I case of inverted papilloma and 1 case of granulomatous necrosis. CONCLUSION: The differential diagnosis between nasal polyps and the other nasal cavity masses is possible by characteristic bone changes and their sites of origin revealed on CT. In addition, it is possible to differentiate malignant masses from benign in most cases.

Status of margins and the size of the lesion are independent prognostic factors of ductal carcinoma in situ (DCIS). Histologic grading of DCIS and expression of biologic marker also appear to act as prognostic factors. However, DNA ploidy analysis using flow cytometry in the DCIS and atypical ductal hyperplasia (ADH) has been rarely reported, and the biologic behavior of ADH is unknown. We performed immunohistochemical staining and DNA ploidy analysis using flow cytometry on 45 cases of pure DCIS without microinvasion and 34 cases of ADH to compare the expression of biologic markers and DNA ploidy patterns according to the histologic grade of DCIS, to evaluate the usefulness of the Van Nuys classification, and to investigate the biologic behavior of ADH and low grade DCIS. A total of 41.9% of DCIS and 32.1% of ADH were detected mammographically in asymptomatic patients. The most common subtype of the high grade DCIS was comedo type (56.3%), while the low and intermediate grade DCIS were cribriform type. Expression of ER, c-erbB-2 and Ki-67 proliferative index (PI) was significantly associated with nuclear grade and histologic grade of DCIS. Expression of c-erbB-2 was also significantly correlated with presence of necrosis. In low grade DCIS, Ki-67 PI was significantly higher than ADH. A total of 63.6% of DCIS and 70% of ADH were diploidy and 15.9% of DCIS was aneuploidy. There was no aneuploidy in ADH. No significant association was noted between DNA ploidy and histologic grade or nuclear grade. However, in high grade DCIS, the frequency of aneuploidy was high. In conclusion, histologic grading of DCIS employing nuclear grade and necrosis is a useful tool accounting for biologic behavior. High grade DCIS and comedo DCIS impart aggressive biologic behavior and suggest a higher possibility of local recurrence or progression to invasive carcinoma. In the differential diagnosis of ADH and low grade DCIS, the use of Ki-67 PI and DNA ploidy analysis by flow cytometry will be helpful for accurate diagnosis and prediction of biologic behavior.

PURPOSE: Knee IVIR images were repeatedly obtained after intravenous administration of gadopentetate dimeglumine to evaluate the arthrographic effect and to determine the optimal scan timing and technique. MATERIALS AND METHODS: Sagittal Tl-weighted (650/15) sequences were repeated before and after intravenous gadolinium enhancement in 26 patients who were divided into exercise (14/26) and nonexercise (12/26) groups. Fourteen patients in exercise group were allowed to move the affected knee joint actively for 10 minutes immediately after the first post-enhancement scan and before repeating scans. The signal intensities in central and peripheral portions of the joint were measured and compared between these two groups. RESULTS: In all cases, enhancement of joint fluid began at peripheral portion and progressed toward central portion. The diffusion rate in exercise group was far faster than that in nonexercise group and homogeneous arthrographic image was revealed within 10 minutes after completion of joint movement. The arthrographic effect continued and the rate of signal decrease was quite slow. CONCLUSION: MR arthrographic image of knee joint can be obtained within 10 minutes after completion of a few minute exercise following intravenous injection of gadopentetate dimeglumine. Intravenous MR arthrography is expected to become an useful method as a convenient alternative to direct MR arthrography.
