Färre DT och fler MR vid skallundersökning på små barn. Svårt avgöra om larmrapport påverkat val av metod, visar studie från Lund

In January 2004, Per Hall et al in an article in British Medical Journal stated that children under the age of 18 months, who underwent CT of the brain, could get negative effects on cognitive abilities in adulthood. At the Department of Radiology, Lund University Hospital, 55 children under the age of 18 months underwent CT of the brain during 2004 compared to 70 children in 2003. MRI of the brai

Procurement of logistics services - a minutes work or a multiple year project?

The purpose of the article is to describe and compare the purchasing process for advanced versus basic logistics services. Further some specific observations are presented from the procurement of advanced third-party logistics services, with respect to service definitions, providers evaluations and contracts. The purchasing process of logistics services will in the future need to be more different

Affine reconstruction from translational motion under various autocalibration constraints

In this paper algorithms for affine reconstruction from translational motion under various auto calibration constraints are presented. A general geometric constraint, expressed using the camera matrices, is derived and this constraint is used in a least square solution to the problem. Necessary and sufficient conditions for critical motions are derived and shown to depend on the knowledge of the i

Särskilt vårdprogram för patienter med höftfraktur

Studies have shown that with the correct treatment the care of patients with hip fractures can be improved. Correct treatment can start in the ambulance and continue with good nursing care; by providing sufficient nutrition and minimizing the use of drugs; and through the prevention, early detection and treatment of postoperative complications such as decubital ulcers and delirium.

Auditory consequences of recurrent acute purulent otitis media

To investigate whether recurrent purulent otitis media results in permanent hearing loss, we studied 2 subgroups of children from a cohort, earlier prospectively followed from birth to the age of 3 years. One subgroup had recurrent acute otitis media (n = 12). and the other had no acute otitis media at all ("healthy" children; n = 21). At follow-up of these subgroups at the age of 10. no child had

Allozyme diversity and geographic variation in the widespread coastal sedge, Carex arenaria

Allozyme electrophoresis was used to investigate the structure of genetic variation in the rhizomatous coastal sedge, Carex arenaria, throughout its European range — from the SW Iberian peninsula to the Baltic region. Material was sampled from 77 sites in five geographic regions. Nine of the 13 investigated loci were polymorphic in the total material and there were interregional differences in the

Stress, immunocompetence and leukocyte profiles of pied flycatchers in relation to brood size manipulation

The two main trade-offs considered determining reproductive patterns in iteroparous organisms are the one between current and future reproduction, and the one between the number and quality of offspring. Recently, it has been suggested that these trade-offs may be mediated by stress-induced reduction in immunocompetence. To test the hypothesis that stress reduces immune function, we investigated t

Spline–Galerkin calculations for Rydberg series of calcium

We are investigating a large number of Rydberg series of neutral calcium, with the help of the recently introduced Spline-Galerkin method. Perturbers belonging to the 4p2, 3d2, 3d5s and 3d4p configurations are investigated and their influence on different Rydberg series is discussed. Results are reported for members of different Rydberg series, with n up to 20-30, and compared with experiment and

Disk with high oxacillin content discriminates between methicillin-resistant and borderline methicillin-susceptible Staphylococcus aureus strains in disk diffusion assays using a low salt concentration

A separation between mecA+ strains of Staphylococcus aureus and strains lacking mecA was achieved by the disk diffusion assay and the agar dilution method, utilizing disks containing 5 microg of oxacillin and inocula of approximately 5 x 10(5) CFU/spot, respectively, provided that agar with 0 to 0.5% NaCl and incubation at 30 degrees C were employed. The 5-microg oxacillin disks clearly discrimina

Effects of CO2 anaesthesia on central nervous system activity in swine

The objective of the study was to examine the changes in central nervous system (CNS) activity and physical behaviour during induction and awakening from CO2 anaesthesia. Two studies, each using pigs immersed into 90% CO2 gas for a period of 60s were performed. In study 1, we monitored middle latency auditory evoked potentials (changes in latencies, amplitudes and a depth of anaesthesia index), el

Classification and prediction of clinical Alzheimer's diagnosis based on plasma signaling proteins

A molecular test for Alzheimer's disease could lead to better treatment and therapies. We found 18 signaling proteins in blood plasma that can be used to classify blinded samples from Alzheimer's and control subjects with close to 90% accuracy and to identify patients who had mild cognitive impairment that progressed to Alzheimer's disease 2-6 years later. Biological analysis of the 18 proteins po

A telescopic stent-graft for aortoiliac implantation

OBJECTIVES: To test a new delivery system for a telescopic stent-graft. MATERIALS: Variable overlap between the components of this stent-graft combination allows length adjustment. This device differs from other multi-component stent-grafts in that both components are contained within a single delivery system. METHODS: The stent-graft was implanted in the distal thoracic to suprarenal aorta of fiv
