The metastatic malignant tumor of the hand is rare condition, and has difficulty in diagnosis at presentation due to simulating other diseases such as osteomyelitis, felon, paronychia, rheumatoid arthritis, and so forth. The treatment of them is very limited and the prognosis is poor. We experienced and going to report two cases of metastaic tumor of the hand, one was from rectal cancer which associated with rheumatoid arthritis and another was from brochogenic carcinoma.

Pleomorphic xanthoastrocytoma is histologically characterized by marked cellular pleomorphism of lipid-laden neoplastic astrocytes and bizarre giant cells showing mitotic figures and high cellularity. Inspite of its ominous-looking microscopic features, howerver, the prognosis is usually favorable. This tumor develops mainly in the supratentorial area of young people and frequently involves the leptomeninges. We experienced a case of pleomorphic xanthoastrocytoma in 18 year-old-male. In addition to the cellular pleomophism, the prominent reticulin fibers surround the individual tumor cells or the tumor cells nests. Immunohistochemical staining and electron microscopy revealed glial fibrillary acidic protein(GFAP) expression and pericytoplasmic basal lamina in the tumor cells.

Deep skin and soft tissue defects with exposed bone and tendon is difficult to treat, because skin graft rarely survives and flap surgery is sacrifice of donor site. Since "Stage I" membrane was developed by Yannas and Bruke in 1980, numerous kinds of artificial skin have been developed. The adaptability of "Terudermis", developed by the Terumo Co., as an artificial skin composed of sponge made of a fibrillar atelocollagen and a heat-denatured atelocollagen, was clinically evaluated on application to 13 cases presenting deep skin and soft tissue defect with exposed bones and tendons from October 1997 to march 1998. Terudermis has the advantage of allowing early incorporation of fibroblasts and capillaries into its collagen sponge due to very weak dehydrothermal cross-linking. Before Terudermis graft, several days of wet dressing and debridement were required to prepare healthy well-vascularized bed because Terudermis was weak on unsanitary wounds. After bed preparation, Terudermis was grafted like usual skin graft. Tie-over bolster dressing or compressive dressing was used case by case. The dressing was opened 2~3 days after Terudermis grafting. Wet dressing was done daily until the skin graft was done. Autologous skin graft was done 2-3 weeks after Terudermis graft. Our clinical results indicated that Terudermis was beneficial in treating 77% of our patients. Through the use of this new method, treatment of severe skin and soft tissue defects that are usually treated by musculocutaneous or other conventional skin flaps can be replaced by Terudermis as an new artificial dermis.

BACKGROUND AND OBJECTIVES: Although a prominent large V wave in left atrial pressure tracing (PVLAP) has been reported to be associated with significant mitral regurgitation (MR) or decreased left atrial compliance (LAC), it is sometimes observed in patients with tight mitral stenosis (MS). The purpose of this study was to determine the prevalence and the hemodynamic significance of PVLAP in tight MS. MATERIALS AND METHODS: Catheterization data before percutaneous mitral balloon valvuloplasty (PMV) were analyzed in 84 consecutive patients and PVLAP was defined as V wave 10 mm Hg higher than mean left atrial pressure (MLAP). RESULTS: PVLAP was observed in 45% (38/84) and factors associated with PVLAP were younger age (p=0.02), higher MLAP (p<0.01), higher mitral gradient (p=0.04), smaller valve area (p=0.01) and low echo score (p=0.02): among them MLAP was the only independent factor in multivariate analysis. The presence of PVLAP had no effect on the result of PMV and successful PMV abolished PVLAP. CONCLUSION: PVLAP was observed not infrequently in these selected patients with MS referred for PMV. The presence of PVLAP was not associated with MR and had good correlation with MLAP, which suggest that PVLAP be determined by decreased LAC.

BACKGROUND AND OBJECTIVES: Although estrogen replacement therapy has been associated with reduction of cardiovascular events in postmeno-pausal women (PMW), the underlying mechanisms are pooly understood. Because the beneficial effect of estrogen on vasomotor function and production of vasoconstrictive endothelin-1 may be a mechanism by which cardiovascular disease events are reduced, we accessed the acute effect of estrogen on endothelial dependent, independent vasodilaton and plasma endothelin-1 level and investigated whether the acute effect of estrogen on vascular response is related to reduced circulating plasma endothelin-1 level. MATERIALS AND METHOD: The diameter of the brachial artery at rest, during reactive hyperemia (FMV) and to response to nitroglycerine (NMV) were measured using high resolution ultrasound. Twenty-one PMW, 523 years old, 8 of whom had hypercholesterolemia were included and randomized to receive placebo, conjugated estrogen 2.5 mg and 5.0 mg with one week between each investigation. FMV and plasma endothelin-1 were assessed before and 30 minutes after iv administration of each substance. Sublingual nitroglycerine (NG) was given at the end of each investigation and NMV was measured. RESULTS: FMV and plasma endothelin-1 were not changed after placebo administration. FMV increased sinigicantly only after administration of CE 5.0 mg in healhy PMW and both after administration of CE 2.5 and 5.0 mg in PMW with hypercholesterolemia. NG induced more significant vasodilation after administration of estrogen than placebo in only PMW with hypercholesterolemia. Plasma endothelin-1 level decreased significantly after administration of CE 5.0 mg in PMW with hypercholesterolemia. We could not find direct correlation between increase of FMV and decrease of plasma endothelin-1 level. CONCLUSION: IV administration of conjugated estrogen improves endothelium-dependent vasodilation in PMW and may improve endothelium-independent vasodilation in PMW with hypercholesterolemia. These finding may be partly originated by reduced plasma endothelin-1 level after estrogen administration.

BACKGROUND: Since better understanding of the associations between blood pressure and blood lipids may provide insight into the mechanisms by which hypertension is associated with increased risk of coronary heart disease, this study is aimed to explore the associations of blood pressure with serum lipids, BMI, age, FBS and life style factors. METHODS AND RESULTS: In this study, 20,826 men and 10,209 women were included for the assessment of the cross-sectional relations of blood lipids, BMI, Blood pressure and Life style factors. Stratified analyses and multivariable methods were used to control for potential confounding anthropometric and lifestyle variables. Total cholesterol and Triglyceride levels increased significantly with increasing systolic or diastolic blood pressure in both sexes. Men of 20-29 years old had steeper regression slopes for blood pressure by total cholesterol level than did women of similar age. In men, the association between blood pressure and total cholesterol level decreased with age, whereas in women, no change was observed regarding age. Body mass index modified the relation, whereas smoking, exercise, and alcohol consumption had little influence on the association. HDL cholesterol level had little influence on blood pressure. In the group of age <40, age accounted more than BMI for hypertension, whereas in group of age > or =40, BMI accounted more. In the group of age < 40, other variables ,besides age and BMI, are suggested to influence more on male hypertension than female hypertension. CONCLUSION: These results provides evidence that there are interrelations between blood pressure, blood lipids and life style factors that may influence the mechanisms of coronary heart disease.
