    Notes: Abstract We present data on the multiplicity structure of inclusive charged hadron production in charged current neutrino and antineutrino freon interactions in the energy range 3–30 GeV resulting from an experiment with the bubble chamber SKAT. Average multiplicities, dispersions and correlation coefficients are investigated. Furthermore, KNO-scaling is studied and average net charges are calculated in different kinematical regions. Our data are compared with results from $$\begin{array}{*{20}c} {( - )} \\ v \\ \end{array} $$ -interactions on an isoscalar target of “free” nucleons to study the influence of nuclear effects.

    Notes: Abstract From April 1992 to May 1994, 780 patients aged from 1 day to 8 years were examined. Sedation of these patients was conducted by giving chlorprothixene orally and, in some cases, chloral hydrate had to be added. The patients were monitored with a pulse oxymeter. Investigations could begin after 50–120 min. In 710 patients (91 %) the first attempt to perform the examination was successful; 70 patients required one or two further attempts. Only two of the 780 patients (0.5 %) showed evidence of respiratory depression. The total number of pediatric MRI examinations performed in 1 year is almost 1000. In the hands of an experienced pediatric radiologist these examinations can be performed entirely without anesthesia.

    Notes: Abstract Pure autonomic failure (PAF; also known as idiopathic orthostatic hypotension or Bradbury-Eggleston syndrome) is an uncommon sporadic disorder, characterized by autonomic failure without other neurological deficits and histopathologically by cell loss in intermediolateral columns and sympathetic ganglia. Few postmortem studies of patients with PAF have been reported in the literature, and none have demonstrated Lewy bodies in distal axons, although this has been described as a feature in Parkinson’s disease with autonomic failure. We report a patient with PAF who had orthostatic hypotension and urinary symptoms for 15 years prior to death at the age of 63 years. Postmortem findings included typical and atypical Lewy bodies in the substantia nigra, locus ceruleus, substantia innominata, and sympathetic ganglia, as well as in autonomic axons in the epicardial fat, autonomic nerve fascicles in periadrenal adipose tissue, and autonomic nerves in the muscularis of the urinary bladder. Sites of autonomic nerve involvement correlated with clinical symptomatology, and thus were a valuable observation in the complete autopsy. Systemic autopsy results should be reviewed carefully in patients with PAF, as Lewy bodies in this disease may be seen in distal axons at a great length from their primary cell bodies.

    Notes: Abstract Four boys are described with partial gigantism of the hands and/or feet, pigmented nevi, hemihypertrophy, subcutaneous hamartomatous tumors and macrocephaly, and/or other skull anomalies. Three of these patients showed an accelerated growth in their first years of life. Two suffered from cystiform pulmonary abnormalities. The children showed normal mental development with the exception of one with traumatic brain damage. Parental consanguinity was not disclosed. As a result of a review of the literature, we can say that these cases do not conform to any well defined entity and would appear to represent a ‘new’ syndrome to be categorized under congenital hamartomatous disorders. The mode of inheritance of the undoubtedly genetically determined syndrome is yet not clearly understood. We propose the term Proteus syndrome for this ‘new’ syndrome.

    Notes: Abstract Three brothers with a constitutional skeletal dysplasia characterized by an excessively retarded ossification, principally of the epiphyses, the pelvis, the hands and the feet, are reported. In the hands and feet the retarded ossification is combined with an abnormal modeling of the bones. All the children appeared normal at birth. At the time of examination a moderate degree of dwarfism could be predicted. There was no mental retardation. All laboratory investigations including chromosomal analyses and examination for acid mucopolysaccharides in the urine were normal. Parental consanguinity suggest an autosomal recessive inheritance. There is no resemblance of this disorder to any of the hitherto described groups of constitutional diseases of bones.

    Notes: Abstract Cockayne's syndrome is a rare familial disorder characterised clinically by premature aging, appearing progressively from the third year on. The radiological manifestations of eight affected children have been studied and summarised. It is concluded that a skeletal survey can provide a roentgenologic pattern suggesting the diagnosis, even when it is inconclusive from the clinical signs during the first years of life. The aetiology of this syndrome is unknown, but the authors postulate the possible role of a defect of thymic hormone which has been found in all their cases.

    Notes: Abstract Anemia is a common complication of autonomic failure and reduced red blood cell mass may contribute to the orthostatic hypotension of these patients. We investigated whether treatment with recombinant erythropoietin improves anemia and increases blood pressure in patients with primary autonomic failure. Three patients with multiple system atrophy and autonomic failure and one with pure autonomic failure were studied. All patients had normocytic normochromic anemia and low (n = 2) or normal (n = 2) serum levels of erythropoietin. Treatment with erythropoietin, 4000 U subcutaneously biweekly for 6 weeks, increased hematocrit and blood pressure in all patients. Hematocrit increased from 33.9 ± 0.7 to 44.3 ± 1.4%, blood pressure in supine position increased from 150 ± 8/87 ± 8 (systolic/diastolic; mean ± SD) to 166 ± 25/92 ± 12 mmHg, and after 3 min in the head-up tilt position from 86 ± 21/47 ± 15 to 102 ± 23/63 ± 12 mmHg, (p 〈 0.05). All patients reported improvement in orthostatic symptoms and increased tolerance to standing. The study shows that treatment with erythropoietin improves anemia, increases blood pressure and ameliorates orthostatic hypotension in patients with primary autonomic failure.

    Notes: Abstract Some YBCO ceramics have been found to exhibit hysteresis of the current/voltage, I/V, characteristics, which reveals at a certain current If greater than critical current Ic a transition with switch from one branch of the I/V curve to another. In present work, the influence of an electric field at 77 K on hysteresis of I/V curves of ceramic YBCO/Ag and YBCO after hydrogen treatment has been studied. It was established that in strong electric field (120 MV/m) the conductivity increases at current I〉Ic, the field effect being observed only in the upper branch of hysteresis loop. The electric field effect in YBCO after hydrogen treatment is reversible. The observed effects are assumed to be associated with a change of grain boundary weak links from S/I/S-to S/N/S-type in the course of hydrogen treatment or addition of silver into ceramics.

    Notes: Abstract The distribution with c.m. rapidity,y, of the net charge of hadrons produced inK − p interactions at 110 GeV/c is presented and compared withK − p and π- p data at several energies from 10 to 360 GeV/c. In both reactions and at all energies the net charge changes sign from positive to negative aty∼0. The total net charge in the forward direction is −0.70±0.02 at 110 GeV/c. It decreases with increasing energy and the results are consistent with a total net forward charge of −1.0 at infinite energies. These results imply that the fragments of the beam and target particles are far from being completely separated even at the highest energies available at present accelerators.

    Notes: Abstract We present inclusive spectra of charged hadrons produced in $$\begin{array}{*{20}c} {( - )} \\ v \\ \end{array}$$ -Freon interactions at average beam energies of about 6 GeV. The experiment was done using the bubble chamber SKAT at the 70 GeV Serpukhov accelerator. In the hadronic energy range,W〈5 GeV, dominantly isotropic events are found. The transverse momentum of the produced particles shows no strongW 2-dependence. Feynman-scaling may be reached forW 2≳10 GeV2, where also theż-spectra are described by the predictions of the parton model. All experimental data are reproduced rather well also by a Monte Carlo model based on ordinary phase space.
