The purpose of this study was to compare the clinical results and the complication rates of a new generation of two intramedullary fixation devices: Proximal Femoral Nail Antirotation® (PFNA) and Gamma3®. We conducted a prospective randomised multicentre trial of 61 patients who underwent a PFNA fixation treatment (31 patients) or a Gamma3 nail (30(More)
In the kidney, aging is characterized by the development of structural changes, including glomerulosclerosis and interstitial fibrosis. Transforming growth factor-beta1 (TGF-beta1) is known to play a critical role in the genesis of these alterations in pathologic conditions. The present experiments were designed to test the hypothesis that TGF-beta1 may be(More)
In this study, we developed a quantitative method with digital image analysis to evaluate the degree of gingival overgrowth (GO), and compared GO in kidney transplant patients treated with cyclosporin A (CsA) (n = 21) or CsA+nifedipine (n = 8) and a group of healthy controls (n = 30). The method was reproducible and reliable. Our findings showed significant(More)
Interstitial fibrosis and morphologic changes in kidney glomeruli, the structural effects of many diseases, lead to significant pathologic alterations. A reliable and objective method to accurately quantify the extent of interstitial fibrosis and the degree of alteration in glomerular morphology is needed for both clinical practice and experimental work.(More)
P-glycoprotein (P-gp) expels hydrophobic substances from the cell, including chemotherapeutic agents and immunosuppressants such as cyclosporin A (CsA) and FK506. Exposure of cultured renal tubular cells to CsA induces P-gp overexpression in cell membranes. Angiotensin II has recently been implicated as the principal factor responsible for progression of(More)
P-glycoprotein (P-gp), encoded in humans by the mdr-1 gene, acts physiologically as an efflux pump to expel hydrophobic substances from cells. This glycoprotein is closely related to multidrug resistance in tumor cells and can be modulated by cyclosporin A (CsA). We investigated the relationship between CsA and P-gp in 52 renal allograft biopsies and in(More)
Endothelin 1 (Et1) is widely expressed in the kidney and is related to several functions and to pathological conditions with progression towards sclerosis. The function of endothelin 3 (Et3) at the renal level is debatable, but it could have an important regulatory function in the reabsorption of water through its action on tubular type B receptors.(More)
This is a rare case of a patient with type 1 multiple endocrine neoplasia (MEN-1) syndrome. The case is further unusual in that the glucagonoma debuted with two synchronic pancreatic masses at the time of diagnosis and with pulmonary metastases as the primary site of metastasis and not the more usual site of the liver.
Immunohistochemical techniques were used to study the presence of ciclosporin A (CsA) and leukocyte subsets in 36 posttransplant renal biopsy specimens histologically diagnosed as acute graft rejection. Glomeruli from patients with CsA deposits contained more leukocytes (p < 0.05) than glomeruli from tissues without deposits. In contrast, the interstitium(More)
