PURPOSE: To evaluate value of post-contrast 3-Dimensional fat suppressed Spoiled GRASS (FS SPGR) in detectiong subtle bony erosion and tenosynovitis of hands and wrists due to early rheumatoid arthritis. MATERIALS AND METHODS: Fourteen MR iraagings of the hands and wrists were performed in 7 early rheu- matoid arthritis without any abnormalities in plain radiography and in 7 healthy volunteers. All subjects underwent MR sequence of coronal 3D FS SPGR with and without contrast enhancornear in 1.5T MR unit. We evaluated the number of the bony erosion and tenosynovitis respectively in pre- and post-contrast FS SPGR images. RESULTS: The abnormal enhancing areas were not demonstrated in 7 healthy volunteers. Seven patients had 25 bony erosions in pre-contrast FS SPGR and 52 bony erosions with tenosynovitis (n=10) in post-contrast FS SPGR. Enhancing joint spaces were shown in 8 cases CONCLUSION: Post-contrast FS SPGR was better than pre-contrast FS SPGR in the evaluation of early rheumaotid arthritis and is valuable as a baseline study.

The estrogen receptor (ER) is present in a wide variety of mammalian tissues and is required for the physiological responses of estrogen, including estrogen-induced tissue-specific changes in gene expression. But most of our knowledge on the regulation of ER mRNA levels comes from in vivo steroid replacement experiments or cancer cell lines that express the ER. Thus the present study was attempted to determine 1) the anterior pituitary ER mRNA levels during rat estrous cycle 2) if estradiol itself directly modulates the ER mRNA levels in cultured rat anterior pituitary using RT-PCR method. In rats with 4 day estrous cycle, the ER mRNA levels in anterior pituitary gland reached to maximum at proestrus 11:00h just before serum estradiol concentration showed the highest. From then, the ER mRNA levels gradually declined during the rest of the proestrus. On the other hands, in cultured rat anterior pituitary cells, the ER mRNA levels were significantly decreased by the treatment of estradiol. These results indicate that the surge of estradiol was proceeded by the increase in pituitary ER mRNA levels during the proestrus and in cultured anterior pituitary cells, estrogen might be involved in the down-regulation of the ER mRNA levels.

Dural metastasis associated with chronic subdural hematoma is very rare in patients with malignant neoplasms; it may be difficult to distinguish malignant neoplasms from chronic subdural hematoma. Chronic subdural hematoma is usually a late manifestation of malignant tumors, which contributes to the severity of the prognosis. The scans obtained by using magnetic resonance imaging or computed tomography may be misleading when a subdural hematoma masks the underlying tumor. Herein, we report a case of a subdural hematoma with dural metastasis of unknown origin in a 45-year-old woman; however, the neoplasm was not detected until autopsy.

There are two major types of vascular birthmarks, hemangiomas, those demonstrating endothelial hyperplasia, and malformation, those with normal endothelial turnover. Venous malformations have previously been treated by surgical excision, where possible. Although not a panacea for all such tumors, the use of sclerosing agents is decidedly preferable in some cases to extirpation with a scapel. The method involves the direct injection of absolute alcohol into the lesion on the fluoroscopic guide. The effect of treatment is satisfactory and there appears tobe no long term complication. We report 2 cases of surgically irresectable and deep-seated venous malformation which were treated sclerotherapy using ethanol.

BACKGROUND: Epidermal grafting using cryotherapy for recipient sites is in widespread use. However the peripheral hypopigmented haloes that occur around the recipient sites require prolon gation of the treatment period. OBJECTIVE: We used a CO2 laser to remove the epidermis of the recipient sites for betteri results. METHODS: We treated lie localized vitiligo patients with CO2 laser to remove t.he epidermis and grafted suction blister rooves. We observed repigmentation and complications 1 month later. RESULTS & CONCLUSIONS : The superiority of this method is demonstrated by the fact 1) all prodedures can be completed on the day of operation 2) the incidence of hypertrophic scar and peripheral hypopigmented halos can be observed.The problems of this method are 1) uneven repigmentation of recipient. sites 2) hyperpigrnentation of recipient sites
