    Title translation Metastasis to the temporal bone may cause acute peripheral vestibular syndrome and impaired hearing.
    Abstract Metastasis to the petrous apex of the temporal bone may cause acute peripheral vestibular syndrome and impaired hearing or be asymptomatic. Contrast computed tomography should be performed to exclude pathology in the temporal bone in patients with vestibulocochlear deficit, a history of cancer and no findings on cerebral magnetic resonance imaging. We describe a case of a 61-year-old man with metastatic prostatic carcinoma to the temporal bone.

    Abstract This study examined the effect of co-ensiling of wheat straw and sugar beet leaves on the biochemical methane potential (BMP) by both lab-scale and pilot-scale co-ensiling. BMP was increased by co-ensiling, and the increase ranged from 19 to 34% after 9months of co-ensiling in lab-scale and from 18 to 32% after 6months of co-ensiling in pilot-scale. No effluent run-off was found through pilot-scale co-ensiling and there was a mass loss of only 0.1%. The study demonstrates that co-ensiling of straw and green biomass has potential as biological pretreatment and for avoiding effluent run-off from pure beet leave silage.

    Abstract The timing with which salmonid larvae emerge from their gravel nests is thought to be correlated with a particular suite of behavioural and physiological traits that correspond to the stress coping style of the individual. Among these traits, aggressiveness, dominance and resilience to stress, are potentially interesting to exploit in aquaculture production. In the present study a series of experiments were performed, with the purpose of characterising behavioural, metabolic and production related traits in rainbow trout juveniles from different emergence fractions. Newly hatched rainbow trout were sorted according to their emergence time from an artificial nest. The early, middle, and late fractions were retained and assessed for their physiological response to stress, growth performance, metabolism, fasting tolerance, and potential for compensatory growth. The early emerging fraction showed proactive behavioural traits; they were faster to reappear following startling, showed a reduced cortisol response following stress,and a reduced metabolic cost of recovery. Emergence time was not correlated with any differences in standard or maximum metabolic rates, but was however, correlated with higher routine metabolic rates, as demonstrated by significantly bigger weight losses during fasting in the early emerging group. Growth rates and feed conversion efficiencies were not significantly different when fish were co-habitated under a restrictive feeding regime, suggesting that early emerging fish are not able to monopolize food resources. The intermediate emerging group, which makes up the bulk of a population and is often ignored, appears to possess the best growth performance traits, possibly because they do not expend excessive energy on dominance behaviour such as the early emerging group, while they are also not overly timid or stress prone such as the late emerging group.

    Abstract Sources contemporary with Danish author Hans Christian Andersen claimed that he did not master the Danish language, which modern studies interpret as specific dyslexia. A systematic study of his diaries from age 20 to age 70 found a mean spelling error percentage of approximately 1.7 (SD = 1%, range = 0%-4%). A methodologically independent reliability study confirmed these figures. Andersen's error percentages in poems and letters from ages 11 to 19 show a typical initial part of a learning curve that, together with the results from the diaries, gives a life span curve of his spelling development. The diaries, letters, and poems contain only insignificant syntactic errors. Andersen's spelling in the above studies is compared with that of his contemporaries and with data from modern studies. His mean error percentages at different ages are equal to the figures from nondisabled participants, but between 2 and 15 times lower than the mean percentages in studies of individuals with dyslexia. A structural analysis of Andersen's spelling errors shows that they are mainly phonologically plausible from ages 11 to 70, and that the proportions of plausible/implausible errors match those of normal achievers, but not those of individuals with dyslexia.

    Abstract Direct determination of serotonin (5-HT) in gut lavage fluid from patients examined due to various gastrointestinal complaints has been achieved. The method involves addition of 5-methoxytryptamine (5-CH3O-HT) internal standard, centrifugation, filtration and injection of the sample supernatant in a liquid chromatographic system coupled to an ion trap tandem mass detector. Electro-spray in positive mode was used to isolate and fragment the protonated ions [5-HT+H]+ and [5-CH3O-HT+H]+ signals 177 and 191 m/z, respectively. Quantification was carried out by extracting the ion fragment chromatograms at 160 and 174 m/z for 5-HT and 5-CH3O-HT, respectively. The relationship 5-HT/5-CH3O-HT was modelled by using a simultaneous design in order to estimate the optimal amount of internal standard to be added to the samples prior to quantification.

    Abstract Kine Gregersen1,2, Jørgen Valeur1,3, Kristine Lillestøl1,3, Livar Frøyland2, Pedro Araujo2, Gülen Arslan Lied1,3, Arnold Berstad1,31Institute of Medicine, University of Bergen, 2National Institute of Nutrition and Seafood Research; 3Department of Medicine, Section for Gastroenterology, Haukeland University Hospital, Bergen, NorwayBackground: Food hypersensitivity is commonly suspected, but seldom verified. Patients with subjective food hypersensitivity suffer from both intestinal and extraintestinal health complaints. Abnormalities of the enterochromaffin cells may play a role in the pathogenesis. The aim of this study was to investigate enterochromaffin cell function in patients with subjective food hypersensitivity by measuring serum chromogranin A (CgA) and 5-hydroxytryptamine (5-HT, serotonin) in gut lavage fluid.Methods: Sixty-nine patients with subjective food hypersensitivity were examined. Twenty-three patients with inflammatory bowel disease and 35 healthy volunteers were included as comparison groups. CgA was measured in serum by enzyme-linked immunosorbent assay. Gut lavage fluid was obtained by administering 2 L of polyethylene glycol solution intraduodenally. The first clear fluid passed per rectum was collected and 5-HT was analyzed by liquid chromatography tandem mass spectrometry.Results: Serum levels of CgA were significantly lower in patients with subjective food hypersensitivity than in healthy controls (P = 0.04). No differences were found in 5-HT levels in gut lavage fluid between patients with subjective food hypersensitivity and the control groups. There was no correlation between serum CgA and gut lavage 5-HT.Conclusion: Decreased blood levels of CgA suggest neuroendocrine alterations in patients with subjective food hypersensitivity. However, 5-HT levels in gut lavage fluid were normal.Keywords: food hypersensitivity, chromogranin A, serotonin, gut lavage fluid, liquid chromatography

    Abstract With increased pressure to redistribute animal manure in order to lower the environmental pressure from agriculture, it seems obvious to consider processing slurry into nutrient rich fractions which can easily be transported. In this paper, an overall analysis of four different separation technologies is presented. The four technologies are Decanter, Funki Manura 2000, Green Farm Energy and Staring. These technologies are all implemented on a full scale in Denmark. In this paper both the economic and environmental aspects are considered, looking at the entire chain from stable to the field. The total investments range from 50,000 to 4 million Euros and the total net costs are from 1 to 7 Euros per tonne for the four different technologies. One of the clear environmental benefits is a better utilisation of phosphorus, but using phytase in feeding is a cheaper first step when reducing phosphorus surplus. Improved nitrogen utilisation is only apparent with the Staring and Green Farm Energy concepts. The conclusion is that the Funki Manura 2000 system is too expensive and the Decanter system a fairly cheap way to reduce phosphorus levels, but other benefits are limited. Staring and Green Farm Energy show the greatest potential, but these systems have not been running long enough to validate the expected results included in this paper.

    Abstract The development of biogas technology in Denmark has been widely encouraged by the government over the last 15 years. The overall reasons for the government concern has been the increasing awareness that centralised biogas plants make a significant contribution to solve a range of problems in the fields of energy, agriculture and environment. This has been documented through related monitoring and R & D activities. To achieve a satisfactory evaluation of centralised biogas plants, a thorough socio – economic analysis is required. Such investigation has been accomplished, and the results are presented in this summary.
