A case of telangiectatic osteosarcoma of the proximal tibia of left leg in 19-year-old man was reported. Radiologically the tumor was aneccentric blow-out osteolytic lesion simulating aneurysmal bone cyst. Pathologically the tumor presented multiple blood filled cystic spaces and anaplastic spindle cells of osteoclastic type and focal osteoid deposition. The patient died 8 months after he underwent high above knee amputation followed by adjuvant chemotherapy. Distinct clinicopathologic finding of telangiectatic osteosarcoma was described with special emphasis on differential diagnosis.

We analyzed the clinical and laboratory features of ten children with acute megakaryoblastic lukemia (M7)and compared the findings with those reported in the literature. The diagnosis was supprted by ultrastructural examination of platelet peroxidase or immunophenotyping for glycoprotein IIb/IIIa. Of the ten children, five were girls and five were boys. The median age at diagnosis was 13 months. Two patients had prominent myelofibrosis and one patient had Down syndrome. Nine patients were treatd with low-dose cytosine arabinoside (10mg/m2)administered intravenously, or subcutaneously, or intramuscularly, twice daily in 21 day courses. Seven patients achieved hematologic response and three patients are alive without evidence of disease. The 4 year event free survival rate was30.0%. It is our impression that the prevalence of acute megakaryoblastic leukemia has been under-estimated, and low-dose cytosine arabinoside treatment may be of value in its management. This approach may be particularily useful in hospitals with scarce well-equipped facilities, since this protocol does not induce profound marrow hypoplasia and intensive supportive measures are not required as they would be with the use of more aggressive drug combination.

A variety of disease states are marked by prolonged and profound eosinophilia associated with localized or widespread eosinophilic infiltrates. Cardiac involvement maybe a major cause of morbidity and mortality of this disease. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocardilic myocarditis by endomyocardial biopsy.

A totally implanted venous access system was inserted in 19 children with cancer. The devices were utilized for the administration of antineoplastic drugs, parenteral fluids, antibiotics, and blood products. Total duration of implantation was 4,046 days for 23 implanted system (range 7-445 days). Complications included cather infection (0.247/100 catheter days), occlusion (0.692/100 catheter days), and dislodgement of needle (0.643/100 catheter days). There were major complications that necessitated removal of catheters, including systemic infections (0.09/100 catheter days) and complete occlusions (0.09/100 catheter days). The system was thought to be safe and convenient in chemotherapy, and permitted full physical activity.

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.

Previous studies have demonstrated that enalapril and verapamil seem to attenuate the cyclosporine nephrotoxicity. However, the mechanisms have not been completely understood, especially on molecular events. The aim of this study was to examine the effect of individual or combined treatment on osteopontin, TGF-beta, endothelin-1 and procollagen alpha 1(I) mRNA expressions. Enalapril (50 mg/L in drinking water) and verapamil (0.5 mg/kg/day, subcutaneously), alone or in combination, were administered to rats with chronic cyclosporine nephrotoxicity (cyclosporine, 25 mg/kg/day, subcutaneously) (n = 5 each). Five rats treated with olive oil vehicle were used as control. After 4 weeks, biochemical parameters were measured, and renal cortical mRNA levels were evaluated by Northern blot analysis. Cyclosporine reduced renal creatinine clearance significantly and induced renal cortical osteopontin, TGF-beta, endothelin-1 and procollagen alpha 1(I) gene expressions around 13.5 +/- 1.3, 2.4 +/- 0.2, 1.5 +/- 0.1, 1.9 +/- 0.1 folds, respectively. Individual treatment with enalapril or verapamil significantly suppressed the osteopontin and TGF-beta mRNA expression, but not endothelin-1 and procollagen alpha 1(I). Combined treatment also inhibited the osteopontin and TGF-beta mRNA expression but there was no difference between combined and individual treatment. In conclusion, enalapril or verapamil significantly blunted the cyclosporine-induced osteopontin and TGF-beta gene expressions. However, combined treatment did not show any additive effect.

The presented case is a 43-year-old male with a painless mass in the right neck for two weeks. Excisional biopsy was performed under the clinical impression of malignant lymphoma, because he experienced lymphoma 32 months ago. Histopathologically, it shows hyperplasia of small blood vessels and lymphoid cells with eosinophilic infiltration, so it was diagnosed as Kimura's disease. This seems to be the first reported case of Kimura's disease developed during follow up period after remission of lymphoma.
