INTRODUCTION: There were 373 patients irradiated after breast conserving carcinoma treatment. A planning computed tomography revealed in 97 of these patients seromas and tissue defects exceeding 2cm in diameter. The cosmetic results in those patients and the impact of seromas herein had to be evaluated. PATIENTS AND METHODS: Mean age was 59 years. A quadrant resection was performed in 17.5 percent of the patients, a segmental resection in 27.8 percent and a tumour excision in 54.6 percent. Radiation therapy was applied with the Linear accelerator and 6 MeV photons up to a total dose in the residual breast of 50 Gy followed by a boost dose to the former tumour bed of 10 Gy. A distinct evaluation and documentation of therapy related side effects and the resulting cosmesis was done in 51 patients. RESULTS: In all the examined seroma patients there were moderate acute skin reactions grade 1 to 3. As late effects in 82.3 percent scar indurations were noticed. At the skin 51 percent showed enhanced pigmentation, 68.6 percent atrophia and only 11 percent teleangiectasia. Subcutaneous fibrosis occurred in 56,9 percent of the patients, 78.4 percent of the women had breast asymmetries. In 41.2 percent there were a lymphedema subcutaneously, in 72.5 percent impaired sensibility. The overall cosmetic result documented with a 5 point score was "very good" (score 1) in 19.6 percent and "good" (score 2) in 33.3 percent, 37.3 percent were "satisfactory" (score 3) and 9.8 percent "bad" (score 4) respectively. No "very bad" results (score 5) were seen. CONCLUSIONS: The cosmetic results in the examined group of seroma and hematoma patients were inferior to those reported in the literature. We conclude that postoperative seroma and hematoma have an adverse effect on the resulting cosmesis and that their frequency and extent have to be reduced in future by the responsible surgeons.

The purpose was to retrospectively review the data of 27 patients with renal insufficiency who underwent conventional angiography with gadolinium-based contrast agents (GDBCA) as alternative contrast agents and assess the occurrence of nephrogenic systemic fibrosis (NSF) together with associated potential risk factors.

Myocardial fibrosis contributes to hemodynamic and cardiac functional alterations commonly observed posttransplantation. Cardiac mast cells (MC) have been linked to fibrosis in posttransplantation hearts. Eotaxin, which has been shown to be involved in fibrogenesis, has been demonstrated to be increased in production in cardiac macrophages. The aim of our study was to correlate myocardial fibrosis during heart transplant rejection in the rat with eotaxin/chemokine [c-c motif] ligand 11 (CCL11) expression, and with various subtypes of infiltrating cardiac MC, namely connective-type MC (CTMC) and mucosa-type MC (MMC).

In infected lungs of the cystic fibrosis (CF) patients, opportunistic pathogens and mutated cystic fibrosis transmembrane conductance regulator protein (CFTR) contribute to chronic airway inflammation that is characterized by neutrophil/macrophage infiltration, cytokine release and ceramide accumulation. We sought to investigate CF lung inflammation in the alveoli.

Activation of hepatic stellate cells (HSC) and transdifferentiation to myofibroblasts following liver injury is the main culprit for hepatic fibrosis. Myofibroblasts show increased proliferation, migration, contraction, and production of extracellular matrix (ECM). In vitro, HMG-CoA reductase inhibitors (statins) inhibit proliferation and induce apoptosis of myofibroblastic HSC. To investigate the antifibrotic effects of atorvastatin in vivo we used bile duct ligated rats (BDL).

In an experimental murine model of unilateral ureteral obstruction, Togao et al demonstrated that diffusion-weighted (DW) magnetic resonance (MR) imaging can depict and enable monitoring of abnormal changes in the progression of renal fibrosis; because these microstructural changes are complex and multifactorial, future studies focused on their specificity should be performed before they are applied in clinical trials.

Different mutations in the cystic fibrosis gene (CFTR) are associated with different functional status of the exocrine pancreas. We investigated whether CFTR genotypes determine the risk of pancreatitis in patients with cystic fibrosis (CF).

In questionable cystic fibrosis (CF), mild or monosymptomatic phenotypes frequently cause diagnostic difficulties despite detailed algorithms. CF transmembrane conductance regulator (CFTR)-mediated ion transport can be studied ex vivo in rectal biopsies by intestinal current measurement (ICM).
