    Notes: Abstract Vasoactive intestinal polypeptide (VIP) and substance P (SP) immunoreactivity are reduced in the cutaneous nerves of diabetic patients with peripheral neuropathy. The functional significance of this finding was studied by measuring the forearm sweat response to intradermal methacholine and the effect of coadministration of VIP and SP in six normal subjects, and in six diabetic patients with neuropathy and eight without. Flare responses to the two peptides were also measured. Methacholine-induced sweat output was significantly greater in neuropathic patients compared with the other groups (p 〈 0.05), suggesting upper limb denervation supersensitivity. VIP and SP alone did not evoke sweating in any subject. Injection of VIP or SP reduced methacholine-induced sweating to a similar degree in all groups, except that the reduction was smaller in the nonneuropathic group than in the others (p = 0.028 versus normal subjects, p = 0.014 versus neuropathic diabetic patients). Flare responses to the peptides were markedly reduced in the neuropathic patients compared with the other groups (p 〈 0.01). In neuropathic patients, increased sweat responses and decreased flare coexist with diminished neurophysiological measurements; cutaneous sweating and flare responses provide valuable additional information to conventional methods of neurological assessment in diabetic neuropathy.

    Notes: Zum Thema Die ultima ratio der Lebertherapie, die Lebertransplantation, hat hierzulande und in aller Welt eine zunehmende Bedeutung gewonnen. Die Prognose der Lebertransplantation ist auch langfristig sehr günstig und hat sich aufgrund vieler Voraussetzungen in den letzten Jahren immer weiter verbessert. Nur die mangelnde Bereitschaft zur Organspende limitiert die Anzahl weiterer wünschenswerter Transplantationen, worauf – wieder einmal – hingewiesen sei. Da hauptsächlich über Indikation und Prognose informierte Ärzte am überzeugendsten in ihrem Umfeld auf einen Wandel zugunsten einer positiven Einstellung zur Organtransplantation bewirken können, sei diese Übersicht auch den nicht auf die Behandlung von Lebererkrankungen spezialisierten Kolleginnen und Kollegen empfohlen. Im Mittelpunkt der vorliegenden Arbeit stehen die Indikationen zur Lebertransplantation und deren Prognose. Da sich diese mit der Progredienz des Leidens im Hinblick auf das Transplantationsergebnis verschlechert, sollte bei bestehender Indikation die Lebertransplantation möglichst bald durchgeführt werden. Große Fortschritte wurden auch mit der möglichst individuellen Immunsuppression und antiviralen Therapie erzielt. Die Ergebnisse in der Entwicklung therapeutischer Systeme, die z.B. im Falle eines aktuen Leberversagens bis zur Bereitstellung eines Spenderorgans vorübergehend die Leberfunktion überbrücken helfen, sind ermutigend. Auch darüber wird referiert.

    Notes: Abstract We performed a study to evaluate the influence on visual function of intraocular straylight after photorefractive keratectomy (PRK). We present 4 eyes of 4 myopic individuals, who had contacted our clinic for keratorefractive surgical treatment. PRK's were performed with a Summit laser, using a 5 mm ablation zone. The straylight meter was used to measure the amount of intraocular scattered light, the physical cause of glare complaints, before and after PRK. This apparatus uses the direct compensation method to assess the amount of intraocular light scatter. The results showed a significant increase in straylight values, in the tested eyes, during the first two weeks after PRK. After the initial rise, straylight values returned to preoperative levels, except for two eyes that clearly developed a haze higher than grade two. Instead of returning to baseline levels, straylight values remained significantly higher in these eyes.
