Intravertebral vacuum cleft in collapsed vertebra was considered as a typical finding of avascular necrosis. However, several authors reported some cases of intravertebral vacuum cleft in primary or secondary neoplasm, or in spondylitis emphasiging the differenhal diagnosis. MRI is known to be a useful diagnostic modality for diferentiation between benign and malignanct conditions causing vertebral collapse. We report MRI findings of two cases with intravertebral vacuum cleft diagnosed as posttraumatic collapse with avascular necrosis on radiological and clinical bases.

CT is a valuable diagnostic modality in evaluation of bladder injury, extension of paravesical hematoma, pelvic bone fracture or injury of adjacent soft tissue although the diagnostic accuracy of bladder injury itself is lower than that of retrograde cystography. We analized CT findings in thirty cases of bladder injury or paravesical hematoma due to blunt lower abdominal or pelvic trauma and compared them with operation fildings in eight cases. IVP in eight cases and cystography in fifteen cases. The types of bladder injury were classified as contusion, intraperitoneal bladder rupture, extraperitoneal bladder rupture and combined rupture. The locations of paravesical hematoma were classified as perivesical, prevesical or combined. There was no close relationship between the types of pelvic bone fracture and distribution of paravesical hematoma. The paravesical hematomas in fifteen patients without bladder injury were located in prevesical space only. Perivesical hematomas were noted in nine of fifteen patients with bladder injury and were not noted in patients without bladder injury. Thus, we concluded that the presence of perivesical hematoma on CT is a diagnostic sign of bladder injury even though extravasation of contrast from the bladder is not identified, and if there is extraperitoneal hematoma, possibility of bladder injury or other pelvic trauma should be considered.

Twenty-two cases of idiopathic myocardiopathy were observed during the period of 1962 to 1971 and follow up clinical study was made in 5 cases. The criteria of diagnosis was based mainly on exclusive diagnosis in etiology unknown marked cardiomegaly. 1) Male and female ratio of idiopathic myocardiopathy was 1.1:1 and age of onset were distributed from first decade to fifth decade with similar number of cases. 2) Cardinal symptoms were dyspnea, palpitation, chest pain and cough. Common physical findings were protodiastolic gallop (in 2 cases), moist rales (in 3 cases) and hepatomegaly(in 3 cases). 3) Laboratory findings were normal except elevated T.T.T. in one case. 4) Electrocardiogram were abnormal in all cases. There were 3 cases of left ventricular hypertrophy, 3 cases of non-specific ST-T changes and one case of first degree A-V block, intraventricular conduction defect, abnormal Q wave and low valtage, respectively. 5) After medical treatment, symptoms were improved in 4 cases but heart size was reduced in only one case and E.C.G. abnormalities were unchanged in all cases.

OBJECTIVE: Angiogenesis is a critical factor in the progression of solid tumors. The mechanisms responsible for angiogenesis in cervical neoplasia, however, are not well defined. Our study was aimed to determine the expression of VEGF(Vascular Endothelial Growth Factor), its receptor(KDR), and TGF-beta1(Transforming Growth Factor-beta1) in cervical neoplasia, to determine the role of these angiogenic factors in preinvasive(dysplastic) process and the progression of cervical cancer and to investigate the progression of angiogenesis in the transition from normal cervix to invasive squamous cell carcinoma of the uterine cervix. METHODS: The cervical lesions of 76 patients were punch biopsied and paraffin embedded. Among these, 5 were normal cervix, 36 were cervical intraepithelial lesion I-III, and the other 35 were invasive squamous cell carcinomas. The tissues were immunostained with antiVEGF, antiKDR, and antiTGF-beta1 polyclonal antibody. RESULTS: The expression of VEGF, KDR, and TGF-beta1 in CIN III was stronger than those of CIN I(p<0.01). Their expression were not significantly different among the each staged cervical cancers(p>0.01). CONCLUSIONS: These observations suggest that VEGF, KDR, and TGF-beta1 are important angiogenic factors in cervical neoplasia, especially in an early event to neoplastic transformation of cervical tissues, but these angiogenic factors are not associated with the progression of cervical cancer.

Neutrophilic eccrine hidradenitis(NEH) was originally described in 1982 by Harrist et al. in a patient with myelogenous leukemia receiving chemotherapy. Clinically NEH represents various cutaneous manifestations with or without tenderness and pruritus. Histologic examination demonstrates a neutrophilic infiltrate within and around the eccrine gland and degeneration of the eccrine gland structures. Although the pathogenesis and possible cause of NEH remain unknown, it is probably an unusual cutaneous reaction to chemotherapeutic agents. A few cases of infection associated eccrine hidradenitis are found in the literature. We report three cases of neutrophilic eccrine hidradenitis. Two cases were associated with hematologic malignancy. The third case was associated with an infection of Vibrio vulnificus.

Craniopharyngioma is a benign, slow-growing tumor that constitues 3-9% of all intracranial tumors, and arises from epithelial remnants of the Rathke's pouch. We analized MR (2.0T) findings of ten cases with surgically proved craniopharyngioma retrospectively. CT was avilable in five cases, and Gd-DTPA was used in six cases. Characteristic findings of craniopharyngioma in MRI included multilocularity and variable signal intensities within each loculus that were more prominent in T1WI. Detection rate of calcification in MR was 60%. Six cases with Gd-DTPA enhancement revealed irregular or rim-like enhancement. MRI provides useful informations regarding the location, extent and biochemical characteristics of the oraniopharyngioma as well as its relationship to the neighboring structures which will be valuable in planning surgical resection.

Authors observed the antihypertensive effect of debrisoquin sulfate in 35 cases of essential hypertension and following results were obtained. 1) Results of short term control of blood pressure with debrisquin in 35 hypertensive patients revealed good control in 74.3%, fair in 14.3%, poor in 5.7% and failure in 5.7% of cases. Significant reduction of blood pressure was achieved in 7 of 9 cases of hypertension with addition of hydrochlorthiazide to debrisoquin. 2) During long term therapy with debrisoquin (duration of average 3.9 months), good control cases were slightly reduced(good in 58.6%, fair in 24.1%, poor in 6.9%, failure in 10.3%). But average effective dose of debriioquin was not increased significantly. 3) Antihypertensive effect of debrisoquin was slightly reduced in the cases of severe hypertension, hypertension of over 10 years duration and complication of cerebrovascular accident. 4) The side effects during treatment with debrisoquin were dizziness in 31.4%, headache in 11.4%, dry mouth, blurred vision, general weakness, insomnia in 8.6% respectively. There were no side effects in 48.6% of cases.

In certain low-grade malignant tumors such as chondrosarcoma and giant cell tumor, radical treatments may provide a good chance for cure. And large bony defect after the radical treatment can be filled with the massive bone graft. Recent advances in clinical microsurgery have made free tissue transfer a clinical reality, and Taylor in 1975, first reported the technique of free vascularized fibula graft for the reconstruction of large tibial defects with excellent clinical results. We tried wide excision and free vascularized bone graft in 6 patients with malignant or aggressive bone tumor from April 1981 to November 1985 and followed up for more one year. Mean follow up of free vascularized bone graft is 26.4 months and that of devascularized bone graft is 22.6 months. The results of the free vascularized bone graft were compared with 10 patients who were treated with the wide excision and the devascularized bone graft. In this analysis, free vascularized bone graft is superior to devascularized bone graft in bony union, complications and functional results.
