OBJECTIVE To determine the epidemiological and clinical significance of invasive fungal infections in non-neutropenic patients in intensive care who stay longer than 10 days on the intensive care unit (ICU). DESIGN Prospective epidemiological multicenter study over a period of 11 months, based on strict clinical, bacteriological, serological and(More)
Searching for similar image regions in medical databases yields valuable information for diagnosis. However, most of the current approaches are restricted to special cases or they are only available for rather small data stores. In this paper, we propose a fast query pipeline for 3D similarity queries on large databases of computed tomography (CT) scans(More)
BACKGROUND Picture archiving and communication systems (PACS) contain very large amounts of computed tomography (CT) data. When querying a PACS for a particular series, the user is often not interested in the complete series but in a certain region of interest (ROI), described e.g. by an example view in another series or an anatomical concept. OBJECTIVES(More)
BACKGROUND Patients with hereditary generalized neuromuscular diseases develop respiratory failure and decreased maximal inspiratory pressure (Pi max) due to both, involvement of respiratory muscles in the disease and secondary spine- and thorax-deformity. In recent years mechanical respiratory support was done mostly by hyperbaric pressure ventilation when(More)
UNLABELLED During the period from January to September 1995, 19 patients suffering from ventilatory insufficiency were adjusted to nocturnal nasal intermittent positive pressure ventilation (nIPP) therapy with a new ventilatory apparatus conforming to German regulations governing medical equipment (MedGV III). This equipment had not been available(More)
PATIENTS AND METHODS In our centre, 111 patients with chronic ventilatory insufficiency (33 females, 78 males, age 48 +/- 18 years, range 3 to 76 years) were treated by intermittent positive pressure ventilation between 1982 and 1996. Underlying diseases were neuromuscular diseases in 29%, sleep-related hypoventilation in 26%, kyphoscoliosis in 15%, chronic(More)
Pneumocystis carinii pneumonia is one of the most frequent infectious complications in patients with the acquired immunodeficiency syndrome (AIDS). A prospective trial was initiated to compare azidothymidine alone with azidothymidine plus aerosolized pentamidine as a secondary prophylaxis for pneumocystis carinii pneumonia. 27 patients (24 male, three(More)
