Research on genesis of adipocytic metaplasia in uterine fibroids.

The genesis of lipoleiomyoma has not been explained yet. Immunohistochemical examinations were performed on 17 lipoleiomyomas in women aged 43-82 (mean age: 51 ±9 years). Four types of myomas were distinguished: 1) pure leiomyoma, 2) fibroleiomyoma, 3) hyalinizing leiomyoma, 4) strongly hyalinized myoma, along with three degrees of progression of adipocytic metaplasia: 1) up to 25% of lipocytes, 2) up to 50% of lipocytes, and 3) over 50% of lipocytes in the analyzed sample, along with three degrees of progression of adipocytic metaplasia: 1) up to 25% of lipocytes, 2) up to 50% of lipocytes, and 3) over 50% of lipocytes in the analyzed sample.

The clinicopathological determinants of native arteriovenous fistula failure in patients on maintenance hemodialysis.

Background: Progressive narrowing of the venous part of dialysis fistulae is caused by hemodynamic and inflammatory factors.

Objectives: The pathogenic and clinical determinants of deterioration of the functioning of arteriovenous fistulae in chronically hemodialyzed patients were evaluated.

Material And Methods: The hemodynamic parameters and the activity of inflammatory growth factors in the vessel wall of newly implanted fistulae were assessed and correlated with the clinical course of 34 hemodialyzed patients.

[Infective endocarditis--still a great challenge. Two case reports].

We present two patients with aortic valve disease who developed acute infective endocarditis. In both patients the disease started with infection of the upper respiratory tract. The patients were treated with antibiotics due to pneumonia.
