OBJECTIVE In recent years the incidence of renal cell carcinoma (RCC) diagnosis has increased about 15-20%. It remains to be established whether this increase of incidence is reality or not. The main aim of this study was to analyze the reason for the increase of incidence. METHODS In the present study, 23, 247 autopsies performed in the years 1985-1995(More)
PURPOSE Although radical nephrectomy is the standard treatment for localized unilateral renal cell carcinoma with a normal contralateral kidney, there is ongoing interest in the use of nephron sparing surgery or partial nephrectomy in such cases. The extent of radical surgery in such cases has also been reconsidered in view of the uncertainty regarding the(More)
Purpose To investigate whether five treatment sessions of cup-ping massage (CM) improve chronic non-specific neck pain (cNP) and influence pain related neurophysiologic measures. Methods 50 patients with cNP (age 53.3 ± 10.4 yrs) were examined at baseline and then randomized to treatment (TG) or standard medical care (SMC). Data were collected at baseline(More)
Chronic rhinosinusitis with nasal polyps is considered a subgroup of chronic rhinosinusitis and a significant health problem, but the pathogenesis remains unclear to date. Therefore, we investigated the stemness to determine the role of stem cells in nasal polyps, with additional analysis of the neuronal differentiation potential of nasal polyp cells. We(More)
High numbers of adult stem cells are still required to improve the formation of new vessels in scaffolds to accelerate dermal regeneration. Recent data indicate a benefit for vascularization capacity by stimulating stem cells with lipopolysaccharide (LPS). In this study, stem cells derived from human skin (SDSC) were activated with LPS and seeded in a(More)
Clinical features and the management of adrenal insufficiency are considered with reference to etiology, diagnosis, and treatment. Specifically considered are the management of patients with Addison's disease and metastases. Adrenal insufficiency may go unrecognized in the cancer patients because features such as nausea, vomiting, anorexia as well as(More)
OBJECTIVE The effective and efficient assessment, management, and evolution of surgical processes are intrinsic to excellent patient care. Hence, in addition to economic interests, the quality of the outcome is of great importance. Process benchmarking examines the compliance of an intraoperative surgical process to another process that is considered as(More)
In the last years the incidence of renal cell carcinoma diagnosis increased about 15-20%. The main aim of this study was to analyse the reason of the increase of incidence. In the present autopsy series comprising 23,801 autopsies the percentage of patients who died of renal cell carcinoma is 1.77% in Jena and 1.55% in Königgrätz (200,000 inhabitants each).(More)
