The contribution of hereditary variants in the genes of transient receptor potential channels to neuropathic pain is unknown. We investigated the frequency of transient receptor potential ankyrin 1, transient receptor potential melastin 8 and transient receptor potential vanilloid 1 single nucleotide polymorphisms and their impact on somatosensory abnormalities in neuropathic pain patients. Within the German Research Network on Neuropathic Pain (Deutscher Forscbungsverbund Neuropathischer Schmerz) 371 neuropathic pain patients were phenotypically characterized using standardized quantitative sensory testing. Pyrosequencing was employed to determine a total of eleven single nucleotide polymorphisms in transient receptor potential channel genes of the neuropathic pain patients and a cohort of 253 German healthy volunteers. Associations of quantitative sensory testing parameters and single nucleotide polymorphisms between and within groups and subgroups, based on sensory phenotypes, were analyzed. Single nucleotide polymorphisms frequencies did not differ between both the cohorts. However, in neuropathic pain patients transient receptor potential ankyrin 1 710G>A (rs920829, E179K) was associated with the presence of paradoxical heat sensation (p=0.03), and transient receptor potential vanilloid 1 1911A>G (rs8065080, I585V) with cold hypoalgesia (p=0.0035). Two main subgroups characterized by preserved (1) and impaired (2) sensory function were identified. In subgroup 1 transient receptor potential vanilloid 1 1911A>G led to significantly less heat hyperalgesia, pinprick hyperalgesia and mechanical hypaesthesia (p=0.006, p=0.005 and p<0.001) and transient receptor potential vanilloid 1 1103C>G (rs222747, M315I) to cold hypaesthesia (p=0.002), but there was absence of associations in subgroup 2. In this study we found no evidence that genetic variants of transient receptor potential channels are involved in the expression of neuropathic pain, but transient receptor potential channel polymorphisms contributed significantly to the somatosensory abnormalities of neuropathic pain patients.

Eine technische Kunstform? T1 - The radio art. A technical art form? N2 - Die hier vorliegende Arbeit beschäftigt sich mit dem Thema Hörspiel und der Fragestellung, wie die Technik diese Kunstform beeinflusst hat. Um dies zu untersuchen, wurden verschiedene Hörspiele aus den unterschiedlichsten Bereichen herangezogen und unter drei wesentlichen Aspekten untersucht: 1.) „Der Hörer und das Hörspiel“: Dieser Bereich umfasst eine Darstellung der Zusammenhänge des Hören und Wahrnehmens eines Hörspiels durch den Hörer und die Beeinflussung der Wiedergabe entsprechender Schallvorgänge im Raum des Hörers durch technische und räumliche Aspekte. 2.) „Primär-formative Prozesse“: Innerhalb dieser Kapitel wurde die Beeinflussung der originären Schallereignisse durch den Vorgang der Aufnahme und die dabei stattfindenden Prozesse untersucht. Die wesentlichen und berücksichtigten, die Schallaufnahme beeinflussenden Parameter waren hierbei das Hörspielstudio „im Ganzen“, die Schallwandlung im technischen Sinne, der Einfluss der Stereofonie auf das Hörspiel sowie verschiedene daraus resultierende Formen der Inszenierungen. 3.) „Sekundär-formative Prozesse“: In diesem Bereich wurden gestaltende Prozesse erfasst und untersucht, die die aufgenommenen Schallereignisse beeinflussen und/oder zu gänzlich neuen Klangkonstrukten formen. Dies reicht vom Schnitt oder der Blende bis hin zu komplexen Modifikationen mit einer Vielzahl von radiofonen Effekten. Die Analysen der einzelnen Hörspiele fanden dabei nicht nur aus technischer Sicht statt, sondern standen stets in einem engen Zusammenhang mit den dramaturgischen Vorgängen des entsprechenden Werkes. Darüber hinaus wurden aktuelle Produktionsaspekte für ein Hörspiel berücksichtigt, die zugleich in die Diskussion mit entsprechender Literatur gestellt wurden. Zusammengefasst hat sich gezeigt, dass das Hörspiel eine Kunstform ist, die permanent durch die Technik beeinflusst wurde und wird. Der Zusammenhang zwischen Technik und auditiver Kunstform hat eigene dramaturgische Formen hervorgebracht, die das Hörspiel vor allem als eine eigenständige, von anderen Fachdisziplinen losgelöste Gattung definiert und im Umkehrschluss verschiedenste Fachbereiche für sich beansprucht. N2 - The present work deals with the topic of radio play and the question how the technique influenced this art form. Various radio plays from a wide range of types were examined under three main aspects for this study: 1.) “The receiver and the radio play”: This part comprises a representation of the correlation between the listening and perception of a radio play by the listener and the influence on the reproduction of corresponding sound processes in the listener's room through technical and spatial aspects. 2.) "Primary sound arranging processes": Within these chapters the influence of the original sound events were examined by the processes of the recording. The parts influencing the sound recording were included: the radio play studio "as a whole thing", the change of the sounds in a technical sense while recording, the influence of the stereophony on the radio play_ as well as various resulting forms of the radio play through the productions. 3.) “Secondary sound arranging processes”: This part examined sound arranging processes after the recording. For example how to create sound events or form completely new sound constructions. The range of the secondary sound arranging processes includes techniques from the cut and fade to a variety of radio functions. The analysis of the individual radio plays took place not only from a technical point of view but were always closely related to the dramaturgical processes of the corresponding work. Current production aspects for a radio play and existing literature were taken into account. In summary, it has been shown that the radio play is an art form that has been and is still influenced by technology. The connection between technique and radio art has produced its own dramaturgical forms, which defines the radio play primarily as an independent genre separated from other disciplines. It is an art form which must be supported by other disciplines.

Consequently, guidelines for medical device therapy were established for hypertrophic cardiomyopathy, but not for conditions with only anecdotal evidence of arrhythmias, like Fabry cardiomyopathy. Patients with Fabry cardiomyopathy progressively develop myocardial fibrosis, and sudden cardiac death occurs regularly. Because 24-hour Holier electrocardiograms (ECGs) might not detect clinically important arrhythmias, we tested an implanted loop recorder for continuous heart rhythm surveillance and determined its impact on therapy. This prospective study included 16 patients (12 men) with advanced Fabry cardiomyopathy, relevant hypertrophy, and replacement fibrosis in "loco typico." No patients previously exhibited clinically relevant arrhythmias on Holier ECGs. Patients received an implantable loop recorder and were prospectively followed with telemedicine for a median of 1.2 years (range 0.3 to 2.0 years). The primary end point was a clinically meaningful event, which required a therapy change, captured with the loop recorder. Patients submitted data regularly (14 +/- 11 times per month). During follow-up, 21 events were detected (including 4 asystole, i.e., ECG pauses >= 3 seconds) and 7 bradycardia events; 5 episodes of intermittent atrial fibrillation (>3 minutes) and 5 episodes of ventricular tachycardia (3 sustained and 2 nonsustained). Subsequently, as defined in the primary end point, 15 events leaded to a change of therapy. These patients required therapy with a pacemaker or cardioverter defibrillator implantation and/or anticoagulation therapy for atrial fibrillation. In conclusion, clinically relevant arrhythmias that require further device and/or medical therapy are often missed with Holier ECGs in patients with advanced stage Fabry cardiomyopathy, but they can be detected by telemonitoring with an implantable loop recorder.
