The rim sign in renovascular compromise may be defined as a thin nephrographic rim outlinning a kidney with another wise faint nephrogram. Renal infarction with gelform and blood clots was induced experimentally in 5 dogsand high dose IVP and CT were performed to evaluate renal cortical rim sign after renal infarction. One expireddue to anesthetic technical failure, and one was embolized partially. So we could be obtain the result on 3 dogs.The reults were as follows; 1. The high dose IVP films show cortical rim sign on 24 hrs and 72 hrs films in twodogs. The CT films show rim sign in 3 dogs. 2. The rim sign may be visualized, if the renal artery is occuludedenough to drop perfusion presssure below the authoregulatory range. 3. The high dose IVP and early nephrogramphase are necessary for the rim sign.

The intra-articular osteochondroma arising from soft tissue is very rare and has been reported less than a dozen cases in the English literature. This tumor is the result of extrasynovial metaplasia of the fibrous capsule or of the adjacent connective tissue of a joint. The authors experienced a case of giant intra-articular osteochondroma of the right knee in a 37 year-old man which arised from the medial meniscus. Histology as well as gross findings were consistent with osteochondroma. Excision of the mass with attached meniscus relieved symptoms. No recurrence, or malignant change was identified up to 1 year after excision.

OBJECTIVE: The prolactinoma is the most common pituitary tumor and sometimes shows severe invasiveness to the adjacent cavernous sinus, especially in the male patient. The dopamine agonist can be used as an alternative treatment modality to surgery. But, the transsphenoidal or transcranial approach for tumor removal has been more preferred treatment option of neurosurgeons in invasive prolactinoma. Especially rapid decompression of mass effect and resolution of the neurologic deficit is demanded. The prospective study is done in order to identify the therapeutic efficacy of bromocriptine as an initial treatment option for the invasive prolactionomas. METHODS: Twenty patients with invasive prolactinoma were studied. Preoperative neurological and endocrinological evaluations were done, and size and invasiveness of the tumor was estimated on MRI. Bromocriptine was administrated by increasing dose planning reaching maximum dose at 1month of treatment, with close neurological and endocrinological monitoring. At 3months after treatment, MRI was taken and decision was made whether to continue bromocriptine or to have surgical intervention. RESULTS: Thirteen patients showed excellent result with only bromocriptine treatment. These patients showed not only marked reduction of tumor volume and prolactin level, but also, improving clinical symptoms and other hormonal deficits. 13patients who had visual field defect and decreased visual acuity had all improved visual symptoms. But, the remaining 4patients required surgical treatment due to insufficient reduction of tumor size inspite of normalized prolactin level within 3months. Remaining 2patients had 20~30% of tumor size reduction, but prolactin level was not normalized. One patient required radiation therapy. CONCLUSION: Bromociptine can be used as initial treatment for the invasive prolactinomas with careful monitoring of the neurological and endocrinological status. It should be carefully followed up for tumor size reduction within 3 months after initiation of treatment.

Lipoprotein(a)[Lp(a)] is a LDL-like particle with a glycoprotein called apo(a) attached to its apoB through disulfide bond. Many case-control studies support the opinion that plasma Lp(a) levels were associated with coronary artery disease. This study was conducted to assess the relationship between plasma Lp(a) level and coronary artery disease in Korean population. Serum levels of Lp(a), in addition to other lipids and known clinical risk factors for coronary artery disease were determined in 92 subjects undergoing coronary angiography. Among them 30 patients had no obstruction in the coronary artery(cath-control group), while the others revealed the presence of coronary artery stenosis more than 50%(CAD group). The Lp(a) levels of the CAD group were significantly higher the those of cath-control group(31.8+/-25.0mg/dl vs 14.6+/-11.9mg/dl, p<0.005). Other lipids except triglycerides(166.9+/-70.5mg/dl vs 116.2+/-56.1mg/dl, p<0.005) were not significantly different between two groups. The patients with significant coronary artery disease of two or more vessels were found to have higher Lp(a) levels than those of one vessel disease. Lp(a) levels had no relations with other lipids, diabetes, smoking, hypertension and age. Stepwise discriminant analysis revealed that Lp(a) was the best discriminator among risk factors for coronary artery disease. These results suggested that Lp(a) level was a significant independent risk factor for coronary artery disease.

Sclerosing stromal tumor of the avary(SST) is a rare benign tumor first described as a distinct neoplasm by Chalvardjian and Scully(1973) and confirmed as such by Scully(1977) and Gee and Russell(1979). This tumor was separated from the thecoma fibroma group on the basis of characteristic histolog ic features. We present two caaes of postmenopausal women in seuentieth decades with SST, other reported cases of SSTs are discused.

OBJECTIVES: We investigated the prevalence and functional impairment of premenstrual dysphoric disorder (PMDD) and premenstrual syndrome(PMS) in young women. METHODS: A total of 1063 female college students were recruited from two urban areas(Seoul and Suwon) of Korea. Questionnaires for sociodemographic data and risk factors of PMDD, attitude about menstruation, and the Premenstrual Symptoms Screening Tool(PSST) were applied. RESULTS: The prevalence of severe moderate to severe PMS and PMDD were 16.9% and 11.7%, respectively. There were differences in the alcohol and coffee consumption, severity of menstrual cramp, and family history of PMS among the moderate to severe PMS, PMDD, and no/mild PMS groups. Although some participants did not fulfill diagnostic criteria for PMDD, they showed significant functional impairment. Participants with negative attitude about menstruation reported premenstrual symptoms more frequently than those with positive or ambivalent attitude about menstruation. CONCLUSION: These results suggest that PMS and PMDD were prevalent and associated with functional impairment in young females. Some participants reported significant functional impairments although they did not meet the full DSM-IV diagnostic criteria for PMDD. Negative attitude about menstruation was associated with more premenstrual symptoms experiences.

Adrenal cortical carcinoma is a rare disease both in adults and in children. Most of these tumors are functional, especially in children, producing endocrine syndromes such as virilization, Cushing syndrome, hyperaldosteronism or feminization. We experienced a case of adrenal cortical carcinoma in a 7yr old boy who showed features of virilization such as rapid growth rate, penile enlargement, and pubic hair. This case was diagnosed with typical hormonal findings and abdominal MRI and confirmed by pathologic findings. He was successfully treated by total left adrenalectomy and has been followed up without problem over eight months.
