    Long-term experience in using iotrolan for paediatric gastrointestinal studies (1994)

    Notes: Abstract Over the past 5 years we have used the new dimeric, non-ionic, water-soluble contrast agent iotrolan (Isovist-300) in 370 studies of the paediatric gastrointestinal tract. Iotrolan is by far the best accepted and tolerated contrast agent for young children. Because of its iso-osmolality it can be used without dilution. No ill effects were reported in cases of aspiration or perforation. In all studies very high contrast images were obtained and the required diagnostic information was provided. The only disadvantage of iotrolan is its present high price. However, in view of the small volumes required in children (10 ml is sufficient in 59% and 20 ml sufficient in 92% of investigations) this should not be a major obstacle to its use. Iotrolan promotes a much greater readiness among paediatricians and paediatric surgeons to have gastrointestinal studies performed on very small and very sick babies.

    Differential effect of L-threo-3,4-dihydroxyphenylserine in pure autonomic failure and multiple system atrophy with autonomic failure (1991)

    Notes: Summary Treatment with L-threo-3,4-dihydroxyphenylserine (L-threo-dops), a synthetic precursor of norepinephrine, significantly increased upright blood pressure in patients with multiple system atrophy but had no effect on the upright blood pressure of patients with pure autonomic failure. These results suggest that the site of action of L-threo-dops is central and that its pressor effect requires intact peripheral sympathetic neurons.

    Binokulare dreidimensionale Videookulographie (2000)

    Description / Table of Contents: Abstract Background. It has long been a goal to develop a means to measure squint angles in three dimensions simultaneously. A three-dimensional binocular method is naturally needed especially with surgical procedures that affect three dimensions of ocular motility. Methods. Special modifications of a videographic method provide simultaneous online data on the three-dimensional position of the eyes. The interocular difference is equal to the amount of squint, depending on the direction of gaze, head-tilt/direction of gravity, and convergence. Results. The method introduced provides three-dimensional and binocular documentation of ocular movements. This could lead to improve pre- and postsurgical examination, especially of rotational disturbances, and it could also offer an objective means for comparing the results of various surgical procedures.
    Notes: Zusammenfassung Hintergrund. Die dreidimensionale Videookulographie wird für den strabologischen Bereich modifiziert und als binokulare Methode vorgestellt. Methode/Ergebnisse. Durch die Videoanalyse eines Pupullenbildes kann die horizontale und vertikale Position des Auges bestimmt werden. Rotatorische Bewegungen um die Blicklinie werden mit einem speziellen Überlagerungsverfahren von Irismerkmalen gemessen. Neue Prozessoren ermöglichen eine alternierende Positionsbestimmung mit 25 Hz und ebenso schneller Berechnung der interokulären Positionsdifferenz. Das Bezugssystem in Form einer Art Taucherbrille mit Videokameras ist an den Kopf des Probanden gebunden. Semitransparente Spiegel erlauben u. a. 9 Blickpositionen analog zur Tangententafel. Die freie Beweglichkeit des Kopfes dient zur Messung von Innenohreinflüssen bei okulärer Gegenrollung. Schlussfolgerung. Die vorgestellte Methode ermöglicht die objektive, simultane Untersuchung beider Augen in 3 Dimensionen in Echtzeit und mit Angabe der Schielwinkel in den 3 Dimensionen.

    Cranial ultrasound findings in aspartoacylase deficiency (Canavan disease) (1993)

    Notes: Abstract Canavan disease (CD) is a rare leukodystrophy which is lethal in infancy or early childhood. The underlying biochemical abnormality in CD is a hereditary deficiency ofN-aspartoacylase transmitted in an autosomal recessive fashion. We report on the ultrasound (US), CT, and MRI findings of three unrelated boys with biochemically confirmed CD. At 6 and 9 months of age, two CD patients with rapid neurological deterioration showed markedly enhanced acoustic attenuation of the white matter with the exception of the corpus callosum, giving the appearance of a reversed pattern of echogenicity of cortical gray and subcortical white matter. While gyri and sulci had an almost normal US appearance, the periventricular gray matter featured prominently with increased echogenicity. In contrast another CD patient with a more protracted course had ventricular enlargement when examined by US at 5 and 9 months but no alteration in white matter echogenicity. MRI showed impaired myelinization in all three patients with Canavan disease.

    RFLP maps of potato and their alignment with the homoeologous tomato genome (1991)

    Topics: Biology
    Notes: Summary An RFLP linkage map of the potato is presented which comprises 304 loci derived from 230 DNA probes and one morphological marker (tuber skin color). The self-incompatibility locus of potato was mapped to chromosome I, which is homoeologous to tomato chromosome I. By mapping chromosome-specific tomato RFLP markers in potato and, vice versa, potato markers in tomato, the different potato and tomato RFLP maps were aligned to each other and the similarity of the potato and tomato genome was confirmed. The numbers given to the 12 potato chromosomes are now in accordance with the established tomato nomenclature. Comparisons between potato RFLP maps derived from different genetic backgrounds revealed conservation of marker order but differences in chromosome and total map length. In particular, significant reduction of map length was observed in interspecific compared to intraspecific crosses. The distribution of regions with distorted segregation ratios in the genome was analyzed for four potato parents. The most prominent distortion of recombination was found to be caused by the self-incompatibility locus.

    Notes: Abstract The cross sections of neutrino and antineutrino quasielastic reactions $$vn \to \mu ^ - p,\bar vp \to \mu ^ + n,\bar vp \to \mu ^ + \Lambda$$ were studied in the neutrino energy range between 3 and 30 GeV. In comparison withV-A theory axial mass parameters ofM A =(1.06±0.05±0.14) GeV/c2 from neutrino andM A =(0.71±0.10±0.20) GeV/c2 from antineutrino data were found. The total cross-section for the hyperon production process can be described byM A =1.0 GeV/c2.

    Postoperative nausea and vomiting after Faden operation (2000)

    Topics: Medicine
    Notes: Abstract  · Objective: The purpose of this study was to evaluate the antiemetic effect of prophylactic dimenhydrinate application prior to Faden operation and to compare the incidence of PONV between bimedial Faden operation (BMF) and horizontal recess-resect procedure (R&R). · Methods: Ninety-nine children (4–10 years) scheduled for BMF were included in this prospective double-blind study. Midazolam (0.5 mg/kg body weight, BW) was administered orally for premedication 30 min before induction of anesthesia. Additionally, children weighing ≥23 kg received either dimenhydrinate suppositories or placebo. The placebo group was compared with 148 children who underwent R&R surgery without antiemetic prophylaxis during the same period. Anesthesia was induced with thiopentone (5–10 mg/kg BW) and vecuronium (0.1 mg/kg BW) bromide and maintained with halothane (1–2 vol%) in N2O/O2 (65/35 vol%). Age, height, weight, and incidence of oculocardiac reflex were documented. PONV was classified into ”no vomiting”, ”vomiting without therapy”, and ”vomiting requiring rescue medication”. In the latter case dimenhydrinate was given again. The chi-square test was used for statistical analysis.  · Results: Forty-eight patients received placebo, while 51 received dimenhydrinate. No differences between any groups were observed concerning age, height, weight, and incidence of oculocardiac reflex. Compared to R&R surgery, PONV requiring rescue medication occurred significantly more frequently after BMF (45% vs 23% after R&R). PONV after BMF was significantly less severe in the dimenhydrinate group than in the placebo group. The total incidence of PONV after BMF, however, was not significantly reduced. · Conclusion: The high incidence of PONV after BMF can be explained by the greater invasiveness of BMF than R&R surgery. PONV requiring antiemetic rescue medication can be reduced by preoperative administration of dimenhydrinate suppositories.
