Present diagnostic techniques do not allow the detection of early metastatic spread of tumor cells, although this spread largely determines the clinical course of patients with small primary cancers. By use of monoclonal antibody CK2 to the epithelial cytokeratin component number 18 (CK18), individual disseminated carcinoma cells present in bone marrow of(More)
OBJECTIVE Sepsis is associated with an increase in reactive oxygen species and low endogenous antioxidative capacity. We postulated that high-dose supplementation of sodium-selenite would improve the outcome of patients with severe sepsis and septic shock. DESIGN Prospective randomized, placebo-controlled, multiple-center trial. SETTING Eleven intensive(More)
OBJECTIVE To compare the performance of a coagulation score-the new scoring system for diagnosing disseminated intravascular coagulation (DIC)-with the Acute Physiology and Chronic Health Evaluation (APACHE) II and Logistic Organ Dysfunction score in mortality prediction. DESIGN Single-center retrospective study. SETTING Medical intensive care unit of(More)
In areas with severe selenium deficiency there is a higher incidence of thyroiditis due to a decreased activity of selenium-dependent glutathione peroxidase activity within thyroid cells. Selenium-dependent enzymes also have several modifying effects on the immune system. Therefore, even mild selenium deficiency may contribute to the development and(More)
BACKGROUND Metastasis is generally looked on as a late event in the natural history of epithelial tumours. However, the poor prognosis of patients with apparently localised lung cancer indicates that micrometastases occur often before diagnosis of the primary tumour. METHODS At primary surgery, disseminated tumour cells were detected immunocytochemically(More)
The emerging clinical relevance of bone marrow micrometastasis has prompted several investigations, using a variety of immunocytochemical approaches. The present study was designed to evaluate some of the variables affecting the immunocytochemical detection of individual epithelial tumor cells in bone marrow. Using an alkaline phosphatase-antialkaline(More)
OBJECTIVE The influence of gender as a prognostic variable in patients with severe infections is still controversial. Sex steroid hormones have an important impact on the immune system and vice versa, and prospective studies on the hormonal changes during severe infection are lacking. The objective was to compare the influences of gender and adrenal sex(More)
Loss and gain of cell surface molecules determines the mobilization, emigration and invasiveness of epithelial cancer cells. As a first approach to gain further insight into these processes, we have followed two strategies: (1) to identify tumour cells which have disseminated early from primary carcinomas and to obtain information about the phenotype and(More)
Early microdissemination of tumour cells determines the prognosis of patients with apparently localised non-small cell lung cancer (NSCLC). Monoclonal antibodies to epithelial antigens can now be used to detect single carcinoma cells present in mesenchymal secondary organs such as bone marrow or lymph nodes. The present study was designed to obtain insights(More)
PURPOSE OF REVIEW To review the reason for and clinical effects of selenium supplementation in critically ill patients. RECENT FINDINGS Selenium-dependent enzymes and selenoprotein P regulate immune and endothelial cell function. Obviously not the anorganic compounds of selenium but the activity of selenium-dependent enzymes is the most important factor(More)
