During the past years new developments in peritoneal dialysis (PD) technique have resulted in continuous improvement of patient outcome. The importance of salt and fluid balance, residual renal function and peritoneal glucose load are of increasing interest, whereas small solute clearances have lost importance. In patients with high peritoneal transport rates automated PD (APD) is indicated. However, APD can also be chosen as initial PD treatment since recent studies show comparable or even better survival as compared to continuous ambulatory PD patients. Alternative PD solutions improve peritoneal ultrafiltration (icodextrin), reduce peritoneal glucose load (amino acid solution, icodextrin) and protect the peritoneal membrane (solutions with low concentration of glucose degradation products). Infection risk can be reduced when using antibiotic creams, but resistances should be considered. Ongoing studies will clarify if non-antibiotic agents, e.g. medihoney, are effective in preventing PD-associated infections. Due to these improvements PD and hemodialysis have become equivalent treatments.

The early and unexpected death of Wolfgang Amadeus Mozart (Salzburg, 1756 - Vienna, 1791) was a mystery from the very first day and the subject of wildest speculations and adventurous assertions. Over the last 100 years, medical science has investigated the physical sufferings and the mysterious death of Mozart with increasing intensity. The aim of this article was to recreate Mozart's pathography relying on the his correspondence with father Leopold and sister Nannerl and on reports from his physicians and contemporaries. The rumour that Mozart was poisoned followed shortly after his death on 5 December 1791, at the age of 35, and has survived to this day. The alleged culprits were his physician van Swieten, Mozart's freemasons lodge, and the Imperial Chapel Master Salieri. Mozart however died of chronic kidney disease and ultimately of uraemia. If kidney damage reaches a critical point, even a minimum additional stress can lead to its failure. This usually occurs in the fourth decade of life. Next time we listen to Mozart, we should remember that this apparently happy person was actually a precocious boy, ripped of his childhood, whose short life was an endless chain of complaints, fatigue, misery, concern, and malady.

Over the last 50 years nephrology has seen milestone achievements in basic sciences as well as in clinical medicine. This article describes the start of clinical nephrology in Austria in the 1950's and the significant changes over the last decades. With 625 patients/pmp Austria has worldwide one of the highest numbers of patients treated for endstage renal disease. In 1995, 5020 patients were alive on replacement therapy, equally distributed between transplanted and dialyzed patients. An overview over the developments that led to Austria's prominent role in the treatment of end stage renal disease is given.

Mozart, perhaps one of the greatest geniuses of modern age, died mysteriously at the age of 35 in Vienna in 1791. The causes of his death are still somewhat obscure and debated since we do not have any documentation acceptable by current scientific standards. Inevitably, the conclusions reached are highly debatable. In the present article the various interpretations of Mozart's death are taken into consideration-from his possible poisoning to causes of death more acceptable by the present diagnostic criteria. We suggest that the terminal cause of death was brain hemorrhaging or stroke, complicated by broncopneumonia and associated with renal failure induced by proliferative glomerulonephritis and glomerulosclerosis.
