A 28-year-old woman had a 13-month history of skin-colored, well-circumscribed, hyperkeratotic plaques on both heels. Histological examination showed hyperkeratosis and acanthosis in the epidermis. Special stain for elastic tissue revealed marked fragmentation, diminution and thickening of elastic fibers in the dermis. We report a rare case with the lesions of acrokeratoelastoidosis on both heels.

2.Involvement of Polyamine in Growth Hormine Secretion from the GH3 Cells.
Journal of Korean Society of Endocrinology 1998;13(3):313-323
BACKGROUNDS: Polyamines are known to be essential for cell growth and differentiation. Recently, possible roles of the polyamine in signal transduction as neurotransmitter, modulator, or second messenger are suggested in many studies. Furthermore, it is widely studied that possible roles of polyamine are involved in the action of hormone. Thus, it was to investigate the effect of polyamines in the cell proliferation and secretion of GH from the GH cells. METHODS: Cells(5*10 cells/mL) were incubated for 3 days in DMEM containing test drugs and labeled with 20pCi/mL of [S]-methionine for 2 hr. Proteins secreted into the medium were separated by 13% SDS-gel electrophoresis, then autoradiography was performed to identify radiolabeled proteins. [S]-methionine labelled GH was identified by radioimmuno-precipitation. Total protein synthesis was determined from the radioactivity of the cell homogenate by liquid scintillation counter. The intracellular polyamine content was determined by HPLC. RESULTS: Externally added polyamines(putrescine, spermidine, spermine) induced cell proliferation in a dose-dependent manner at proper concentrations, specifically 50pM putrescine increased GH secretion, DFMO or MGBG, which is polyamine biosynthetic inhibitor, inhibited GH secretion in a dose-dependent fashion, In the cells treated with 20mM or 0.01mM MGBG, total protein synthesis were decreased only to 90 or 76% of the control levels and cell proliferation was also slightly inhibited. However the secretion of GH was severely blocked to 37% or 35% of the control. Hydrocortisone at 5 pM stimulated the secretion of GH to 153% of basal secretion, also doubled intracellular putrescine content. CONCLUSION: The present data show that externally added polyamines induced cell proliferation and GH secretion. Also, extemally added putrescine stimulated GH secretion significantly. GH secretion was inhibited by polyamine metabolic inhibitor in a dose-dependent manner and polyamine metabolic inhibitors, at proper concentrations, specifically blocked GH secretion without any significant influence on the total protein synthesis. The above results imply the involvement of polyamine in GH secretion.

Fracture of capitellum humeri, so called Kocher fracture, was first described by Haln in 1853. It is rare and has been occured 0.5% to 1% of incidence of all elbow fracture. The mechanism of this fracture mostly results when one tries to break a fall and lands on the hand with the elbow in some degree of flexing or falls directly on the elbow in a position of full flexion. This case had been occured in a secondary motion

In 1941, Jaffe and coworkers studied a lesion with histologic appearance of fibrous stroma, pigmented deposition and histiocytic infiltration as well as giant cell, for which they named pigmented villonodular synovitis, bursitis and tenosynovitis. Thereafter many authors have discussed etiology, clinical and radiological features, pathology and treatment regarding the disease. Almost all, this disease is monoarticular and knee joint is most common site. We experienced a case of localized pigmented villonodular synovitis involving an shoulder joint which was treated by local excision and obtained good result.

Distal radial fractures are recognized as very complex injuries with a variable prognosis that depends upon the fracture type and the treatment method. The purpose of this study is to compare radiological and clinical result between external fixation and external fixation with primary bone graft in intraarticular comminuted fracture of distal radius. From January 1993 to December 1995, 32 patients with comminuted intraarticular fractures of the distal radius were treated using a external fixation. 15 cases were treated with ligamentotaxis without bone graft and 17 cases were treated with additional primary bone graft. In last follow-up examination, the mean loss of radial length, radial inclination and volar tilt were less in with bone graft group than without bone graft group. According to Demerit point system Excellent to good results were obtained in 88.2% in cases of external fixation and bone graft group, 66.6% in cases of only extemal fixation group. External fixation combined with primary bone graft is more useful method for the reconstruction and treatment of comminuted intraarticular fractures of the distal radius than closed reduction and external fixation because cancellous bone graft not only provides early mechanical stability but also helps to reduce and supports the depressed intraarticular fragments. Furthermore, this method not only prevents late collapse of fracture but also enhance fracture healing.
