[DreKiP - an outpatient treatment program for children and adolescents with headache].

Headaches are a frequent health problem among children and adolescents. The ocurrence of headaches and the resulting impairments in the quality of life and activities of daily living are modulated by biopsychosocial interactions, which necessitate a complex treatment program. The Dresden Childrens Headache Program (DreKiP) is a multidisciplinary therapy program consisting of eight modules for children and adolescents: education, stress relief, relaxation techniques, physical fitness, climbing therapy, art therapy and sensory training.

[Prospective randomized trial of a modified standard multislice CT protocol for the evaluation of multiple trauma patients].

Purpose: To evaluate whether modification of a standard multislice CT (MSCT) protocol might improve the diagnostic work flow in patients with multiple trauma without relevant loss of image quality.

Materials And Methods: Between September 2002 and September 2003, 80 multiple trauma patients underwent 4-slice CT encompassing head, thorax, abdomen/pelvis and spine. All patients were randomly assigned to either protocol A or B: Protocol A included serial scanning of the head (collimation 1 mm, 350/380 mAs/120 kV) and spiral scans of thorax, abdomen/pelvis and spine (collimation 2.

Na+ gradient-dependent transport of hypoxanthine by calf intestinal brush border membrane vesicles.

The properties of hypoxanthine transport were investigated in purified brush border membrane vesicles isolated from calf proximal and distal jejunum. Hypoxanthine uptake in the vesicles was stimulated by a transmembrane Na(+) gradient and an inside negative potential resulting in a transient accumulation of intravesicular hypoxanthine, especially in the proximal jejunum. Na(+)-dependent hypoxanthine uptake at this site seemed to occur by two saturable transport systems, a high affinity (K(m)=0.

Nucleosides are efficiently absorbed by Na(+)-dependent transport across the intestinal brush border membrane in veal calves.

In previous work, a comparatively high capacity for Na(+)-dependent transport of nucleosides across the intestinal brush border membrane (BBM) was observed in dairy cows, which might be related to digestion of the large amount of nucleic acids present in ruminal microorganisms in the ruminant small intestine. If this were the case, the capacity for Na(+)-dependent intestinal nucleoside transport should be much lower in veal calves, in which only small amounts of nucleic acids, nucleotides, and nucleosides reach the small intestine via the milk replacer. To test this hypothesis, we investigated Na(+)-dependent transport of 3H-labeled thymidine and guanosine across the BBM using BBM vesicles (BBMV) isolated from the small intestine of veal calves.
