PURPOSE:To evaluate the factors influencing the prognosis in avascular necrosis(AVN) of the femoral head by MR. MATERIALS AND METHODS:Radiographic and MRI findings of twenty-three patients(30 cases, aged 23-67 years) with AVN identified clinically and radiologically were evaluated. The radiography included follow up study for at least 6 months. The mean age of these patients was 43 years and M: F ratio was 20: 3. MR imaging was performed at 1. 5T unit using T1- and T2-weighted coronal and Tl-weighted sagittal and axial spin echo sequences. We categorized the changes of the femoral head on radiographic follow-ups to three grades of mild, moderate and severe. We also analyzed the changes of the signal intensity and sizes of the lesion at sagittal and coronal MR images. On MR imaging we classified the extent of AVN of the fernoral head to 2 grades according to the size of lesion. RESULTS:In the cases of mild changes in fernoral head on radiography, the mean age of the patient was 37 years and the extent of AVN was below 1/2 in eleven out of seventeen cases. In the cases of moderate changes, the mean age was 43 years and the extent was above 1/2 in five out of seven cases. In the cases of severe changes, the mean age was 60 years and the extent was above 1/2 in all 6 cases. With 95% confidence coefficient, comparisons in the age and necrosis extent revealed statistical significance in severe versus moderate changes and in severe versus mild changes. Comparisons in the change of signal intensity on T1 and T2 weighted images showed no statistical relationship between each other. CONCLUSION: We conclude that if patient is younger and has smaller extent of the AVN, bone destruction is slower that these factors may be helpful in predicting the prognosis of AVN. However, the modes of the changes of the signal intensity on T1- and T2- weighted images may not be useful in predicting the prognosis of AVN.

We have experienced a case of occult hepatocellular carcinoma metastasized to the heart in a 41 year old female. The hepatocellular carcinoma invaded the hepatic vein, grew in a snakelike fashion up the inferior vena cava and reached the right atrium. Ultrastural examination in this case confirmed the hepatocellular origin of the tumor.

Chondroid syringoma is a rare primary skin tumor arising from eccrine sweat gland. In 1982, Nasse had found a primary skin tumor having similar morphology as in the mixed tumor of the salivary glands. In 1961, Hirsch and Helwig proposed more descriptive diagnostic term, "Choindroid syringma". The authors experienced two cases of chondroid syringma. The first case was a 47 year old male patient who had had a subcutaneous nodule in the right forehead for two months. It was a well circumscribed mass, that showed tan gray myxoid cut surface with firm consistency. Microscopically, it was a wel diagnosed as chondroid syringoma with tubular, branching lumina. The second case was a 51 year old female patient who had had a subcutaneous nodule in the left forehead for 3 months. It was well circumscribed, ad easily shelled out. It had a typical microscopic features of chondroid syringoma with small, tubular lumina.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

The case is presented a 49-year-old man had several year history with chronic renal failure with hyperlipidemia due to diabetes mellitus. Treatment of hyperlipidemia was started by oral bezafibrate intake 600 mg per day. Several days later, patient noticed muscle weakness and myalgia. The serum CK, LDH, AST levels were remarkably elevated, myoglobulinuria was also noticed The symptoms of the patient were resolved after the drug was discontinued, thus the diagnosis was established as having bezafibrate induced rhabdomyolysis. On the basis of the above description, bezafibrate may induce muscle damage if dose is excess over the renal capacity. Extreme caution is warranted when the patient is placed on bezafibrate and has renal dysfunction.Strict dose adjustment is necessary in taking account of renal function to avoid muscle damage including rhabdomyolysis.

There has been no adequate diagnostic method for the diagnosis of intrascrotal lesions until recent days. Butafter the development of radionuclide testicular scan, early and relatively accurate diagnosis of the testicularlesions are possible. So the authors analyzed the 32 cases of patients who were examined by testicular scan andconfirmed by follow up study or operation, and the results are as follows; 1. These 32 cases consists of 13 casesod epididymitis, 7 cases of testicular torsion, 4 of cryptorchism, 2 of testicular tumor and etc. The over alldiagnostic accuracy is about 69%. 2. In epididymitis, the diagnostic accuracy is 85%(11/13) and the findings ofscan are increased perfusion in radionuclide angiogram and hot activity noted mainly in peripheral portion of thetesticle in static image. 3. In cases o testicular torsion, diagnostic accuracy is 86%(6/7). Acute torsion showsnormal perfusion in angiogram and round cold area instatic image. But in missed torsion, perfusion is increasedand round cold area wit surrounding hyperemia is noted in static image. Radionuclide testicular scan seems to benoninvasive, inexpensive, easily available and simple to perform with low gonadal radiation dose. So it can bevery useful as the first study in patients with acute testicular symptoms.

The surgical release of flexor tendons from their restricting adhesions has historically been a somewhat controversial procedure. Especially clinical efficacy of tenolysis is dependent on early active digital motion. The administration of long acting anesthetics (Bupivacaine) through indwelling catheter after tenolysis relieved pain and so achieved early active digital motion in 12 cases. The times for tenolysis following tendon repair and the followup period were 3 months and 6 months on an average. According to flexor zones classification, in 4 patients the lesion was in zone II, 5 in zone III, 1 in zone IV and 2 in zone V. The results were as follows; 1. The functional results after tenolysis showed up 7 excellent, 4 good and 1 fair. 2. The subjective results of the postoperative pain relief showed up 8 excellent and 4 good out of 12 cases.
