T1 - Cholinergic activity and levodopa-induced dyskinesia: a multitracer molecular imaging study JF - Annals of Clinical and Translational Neurology N2 - Objective: To investigate the association between levodopa‐induced dyskinesias and striatal cholinergic activity in patients with Parkinson's disease. Methods: This study included 13 Parkinson's disease patients with peak‐of‐dose levodopa‐induced dyskinesias, 12 nondyskinetic patients, and 12 healthy controls. Participants underwent 5‐[\(^{123}\)I]iodo‐3‐[2(S)‐2‐azetidinylmethoxy]pyridine single‐photon emission computed tomography, a marker of nicotinic acetylcholine receptors, [\(^{123}\)I]N‐ω‐fluoropropyl‐2β‐carbomethoxy‐3β‐(4‐iodophenyl)nortropane single‐photon emission computed tomography, to measure dopamine reuptake transporter density and 2‐[\(^{18}\)F]fluoro‐2‐deoxyglucose positron emission tomography to assess regional cerebral metabolic activity. Striatal binding potentials, uptake values at basal ganglia structures, and correlations with clinical variables were analyzed. Results: Density of nicotinic acetylcholine receptors in the caudate nucleus of dyskinetic subjects was similar to that of healthy controls and significantly higher to that of nondyskinetic patients, in particular, contralaterally to the clinically most affected side. Interpretation: Our findings support the hypothesis that the expression of dyskinesia may be related to cholinergic neuronal excitability in a dopaminergic‐depleted striatum. Cholinergic signaling would play a role in maintaining striatal dopaminergic responsiveness, possibly defining disease phenotype and progression.

T1 - 3D rotational fluoroscopy for intraoperative clip control in patients with intracranial aneurysms – assessment of feasibility and image quality JF - BMC Medical Imaging N2 - Background Mobile 3D fluoroscopes have become increasingly available in neurosurgical operating rooms. In this series, the image quality and value of intraoperative 3D fluoroscopy with intravenous contrast agent for the evaluation of aneurysm occlusion and vessel patency after clip placement was assessed in patients who underwent surgery for intracranial aneurysms. Materials and methods Twelve patients were included in this retrospective analysis. Prior to surgery, a 360° rotational fluoroscopy scan was performed without contrast agent followed by another scan with 50 ml of intravenous iodine contrast agent. The image files of both scans were transferred to an Apple PowerMac® workstation, subtracted and reconstructed using OsiriX® free software. The procedure was repeated after clip placement. Both image sets were compared for assessment of aneurysm occlusion and vessel patency. Results Image acquisition and contrast administration caused no adverse effects. Image quality was sufficient to follow the patency of the vessels distal to the clip. Metal artifacts reduce the assessability of the immediate vicinity of the clip. Precise image subtraction and post-processing can reduce metal artifacts and make the clip-site assessable and depict larger neck-remnants. Conclusion This technique quickly supplies images at adequate quality to evaluate distal vessel patency after aneurysm clipping. Significant aneurysm remnants may be depicted as well. As it does not require visual control of all vessels that are supposed to be evaluated intraoperatively, this technique may be complementary to other intraoperative tools like indocyanine green videoangiography and micro-Doppler, especially for the assessment of larger aneurysms. At the momentary state of this technology, it cannot replace postoperative conventional angiography. However, 3D fluoroscopy and image post-processing are young technologies. Further technical developments are likely to result in improved image quality.

Dazu wurden 117 Patienten, die sich zwischen März 2011 und Dezember 2012 im Klinikum Fulda einer diagnostischen Angiographie unterzogen, in einer randomisierten offenen klinisch kontrollierten Studie untersucht. Die in der Studie untersuchten Druckverbände stellten sich als gleich sicher und effektiv bei der Blutstillung heraus. Es traten in der gesamten Studienpopulation keine schwergradigen Komplikationen auf. Der Safeguard-Druckverband lässt sich leichter und schneller anbringen und entfernen, als der mit elastischen Binden fixierte ET-Druckverband. Er wurde zudem durch die Patienten besser toleriert und als bequemer empfunden. Zusammenfassend ist der Safeguard-Druckverband nach unkomplizierten diagnostischen Angiographien ebenso sicher, wie der UFO-Druckverband und zeigte darüber hinaus eine höhere Anwender- und Patientenfreundlichkeit. N2 - The aim of this study was the comparison of two types of pressure bandaging with regard to effective hemostasis, patient comfort and user convenience. One hundred and seventeen patients undergoing diagnostic angiography utilizing femoral artery access were examined in a randomized, single center, open, controlled, clinical trial. Both pressure bandages were equally safe and effective in achieving hemostasis. No major complications were observed. The Safeguard pressure dressing was significantly easier and faster to place and to remove than the ET pressure dressing with elastic bandages. Patients also evaluated the Safeguard pressure dressing as significantly more comfortable and tolerable. The study demonstrates that the Safeguard pressure dressing is equally safe as the ET pressure dressing after uncomplicated diagnostic angiography and results in improved patient comfort and user convenience.

T1 - Nuchal skinfold thickness: A novel parameter for assessment of body composition in childhood craniopharyngioma JF - Journal of Clinical Endocrinology & Metabolism N2 - Context: Hypothalamic obesity, cardiovascular disease (CVD), and relapse/progression have a major impact on prognosis in childhood-onset craniopharyngioma (CP). We analyzed nuchal skinfold thickness (NST) on magnetic resonance imaging performed for follow-up monitoring as a novel parameter for body composition (BC) and CVD in CP. Objective: The objective of the study was to identify the association of NST with body mass index (BMI), waist to height ratio (WHtR), functional capacity, and blood pressure (BP) in CP and controls. Design: This was a cross-sectional and longitudinal prospective study in CP patients. Setting: The study was conducted at HIT-Endo, KRANIOPHARYNGEOM 2000/2007. Patients: Participants included 94 CP patients and 75 controls. Interventions: There were no interventions. Main Outcome Measures: Association of NST with BC and BP in 43 CP and 43 controls was measured. Results: NST correlated with BMI SD score (SDS; r = 0.78; P = .001; n = 169) and WHtR (r = 0.85; P = .001; n = 86) in the total cohort and CP patients (NST-BMI SDS: r = 0.77, P = .001, n = 94); NST-WHtR: r = 0.835, P = .001, n = 43) and controls (NST-BMI SDS: r = 0.792, P = .001, n = 75; NST-WHtR: r = 0.671, P = .001, n = 43). In CP, systolic BP correlated with NST (r = 0.575, P = .001), BMI SDS (r = 0.434, P = .004), and WHtR (r = 0.386, P = .011). Similar results were observed for diastolic BP in CP. In multivariate analyses, NST had a predictive value for hypertension in postpubertal CP and controls (odds ratio 6.98, 95% confidence interval 1.65, 29.5], P = .008). During a longitudinal follow-up, changes in NST correlated with changes in BMI SDS (P = .001) and WHtR (P = .01) but not with changes in BP and functional capacity. Conclusions: Because monitoring of magnetic resonance imaging and BC is essential for follow-up in CP, NST could serve as a novel and clinically relevant parameter for longitudinal assessment of BC and CVD risk in CP.

Zur Beurteilung des auditorischen Systems sowie seiner angrenzenden Nachbarstrukturen zählt die neuroradiologische Diagnostik mittels spezieller CT- und MRT-Techniken zu den entscheidenden Kriterien zur CI-Indikationsstellung und der Operationsplanung. In der Literatur finden sich verschiedenste Meinungen zur Bedeutung dieser präoperativen Bildgebungen vor Cochlea-Implantationen und die Wahl einer CT- und bzw. oder einer MRT-Untersuchung zur präoperativen Diagnostik wird diskutiert. So wurden am Universitätsklinikum Würzburg im Zeitraum von 2005 bis zum Jahr 2015 zur Diagnostik vor der CI-Operation eines Patienten meist sowohl eine CT-Aufnahme des Felsenbeins als auch eine MRT-Aufnahme des Schädels angefertigt. Im Rahmen dieser Arbeit sollte untersucht werden, inwieweit diese beiden präoperativen CT- und MRT-Untersuchungen für die CI-Operation und die Ursachenabklärung der Hörminderung von Relevanz waren und ob eine Empfehlung für die zukünftige Wahl der Diagnostikmethoden abgegeben werden kann. Dazu wurden Anamnesen, Voruntersuchungen, präoperative CT- und MRT-Bildgebungen und die Operationsberichte von 705 CI-Fällen bei 549 Patienten, die in diesem Zeitraum operiert wurden, retrospektiv ausgewertet. Die Darstellbarkeiten verschiedener Pathologien, die mit Hilfe der beiden Bildgebungsverfahren detektiert wurden, wurden miteinander verglichen und es wurde überprüft, ob ein Verfahren möglicherweise besser zur Diagnostik bestimmter Auffälligkeiten geeignet war als das andere. Durch die Auswertung der Operationsberichte wurde evaluiert, ob und wie die Befunde der präoperativen Bildgebungen mit den intraoperativen Situationen übereinstimmten und ob diese Befunde die Operationsplanung beeinflusst hatten. Die Ergebnisse dieser Arbeit zeigten, dass die bildgebenden Verfahren zur Ursachenfindung einer nicht abgeklärten Hörminderung beitragen können. Des Weiteren konnte gefolgert werden, dass ein Großteil von Auffälligkeiten im Bereich des Felsenbeins, die mit sensorineuralen Schwerhörigkeiten assoziiert sind, mit hoher Wahrscheinlichkeit sowohl mittels CT- als auch mittels MRT-Untersuchung diagnostiziert werden kann. Für einzelne Läsionen konnte vermutet werden, dass diese nur durch die CT und umgekehrt bestimmte Läsionen nur durch die MRT detektiert werden können. Außerdem zeigte sich, dass die beiden bildgebenden Verfahren auf bestimmte Schwierigkeiten, die während einer CI-Operation auftreten können, präoperativ hinweisen können. Zusätzlich konnte festgestellt werden, dass die Wahl der Implantations-Seite bei einseitig operierten aber beidseits schwerhörigen Patienten neben den CT- und MRT-Untersuchungen in den meisten Fällen von weiteren Faktoren abhing. Aus den Ergebnissen dieser Arbeit konnte gefolgert werden, dass die Durchführung einer präoperativen CT- und einer MRT-Untersuchung die umfangreichste radiologische Diagnostikmethode ist, um eine CI-Operation zu planen, möglichst alle Auffälligkeiten, die zu Schwierigkeiten in der Operation führen können, zu detektieren und Ursachen für eine nicht abgeklärte Hörminderung zu finden. Dennoch sollte, insbesondere unter Berücksichtigung der Strahlenbelastung, die ein Patient im Rahmen eines Felsenbein-CTs erfährt, die Überlegung zugelassen werden, ob zukünftig nur die Durchführung einer MRT-Untersuchung als routinemäßiges Diagnostikverfahren ausreichen könnte. Eine zusätzliche CT-Untersuchung wäre dann nur unter bestimmten Voraussetzungen (z. B. Traumaanamnese des Schädels oder Hinweise auf ein Cholesteatom) indiziert. Weitere Untersuchungen, die zeigen, welche genauen Kriterien dazu seitens des Patienten gegeben sein müssten, sowie Langzeitergebnisse nach erfolgreichen CI-Operationen sollten Gegenstand weiterer Studien sein. N2 - Cochlear implants are the standard treatment for patients with profound sensorineural hearing loss, which cannot be treated with traditional hearing aids. In the process of preoperative diagnostics, both computed tomography (CT) and magnetic resonance imaging (MRI) are used to evaluate the auditory system. The goal of this study was to determine, which kind of results CT and MRI provided and in how many cases the results of CT or MRI influenced the procedure of cochlear implantation. In addition, this study had the aim to provide a possible recommendation, if both CT and MRI are necessary for preoperative diagnostics or if either one imaging modality may be sufficient. The results of this study showed that both CT and MRI can provide information about possible etiologies of hearing loss. Both imaging modalities proved to be able to detect the majority of abnormalities of the temporal bone and provided findings which influenced the procedure of cochlear implantation. Nevertheless, specific lesions were only detected with either CT or MRI. In particular, MRI was able to detect brain lesions, which cannot be seen in CT. Considering these results in combination with the negative aspect of exposure to radiation of CT imaging, MRI might be sufficient for preoperative diagnostics in a substantial part of cochlear implant cases.

T1 - Significance of contrast enhancement in low grade gliomas in children N2 - Bei niedriggradigen Gliomen WHO I° und II° ist das Kontrastmittelverhalten variabel und nicht mit der Prognose assoziiert. Andererseits wurde bei spontanen Regressionen von niedriggradigen Gliomen bei Patienten sowohl mit als auch ohne eine Neurofibromatose Typ I eine Abnahme der Kontrastmittelaufnahme berichtet. Vielleicht deswegen verleitet eine Zunahme des Enhancements oder ein neu aufgetretenes Enhancement nicht selten zur Diagnose einer Tumorprogression. Es stellt sich also die Frage, ob eine Kontrastmittelaufnahme bei LGGs mit einer Größenzunahme somit einem Tumorprogress assoziiert ist. Es lässt sich eine überdurchschnittliche Assoziation einer Änderung der Kontrastmittelaufnahme mit dem Wachstumsverhalten bei LGGs nachweisen. Allerdings ist das Maß für eine Progression oder Regression weiterhin die Größenänderung des Tumors. Auch eine neue Kontrastmittelaufnahme innerhalb eines Tumors hat keine Bedeutung für das aktuelle Staging. Sie findet sich zwar häufiger bei Wachstum aber auch bei regredienten Tumoren. N2 - Low grade gliomas show a variable contrast enhancement which does not correlate with the prognosis. On the other hand, there are several case reports which show a spontaneous regression of tumor size with a decreasing enhancement. The purpose of this study is to answer the question, if there is a correlation between increasing contrast enhancement and tumorprogression. We showed an association between change in contrast enhancement and tumorgrowth, growing tumors tended to show an increasing contrast enhancement and vice versa. But the change in tumorsize was too little to be catgorized as progression/regression. A spot of new contrast enhancement had no prognostic value since it appeared in progredient and regredient tumors. We could show, that there is a significant correlation between change in size and contrast enhancement, but an increasing enhancement without increasing size showed no prognostic value. Tumor progression is defined in increasing volume, increasing contrast enhancement has no impact for the further prognosis.

T1 - c-MYC expression sensitizes medulloblastoma cells to radio- and chemotherapy and has no impact on response in medulloblastoma patients JF - BMC Cancer N2 - Background: To study whether and how c-MYC expression determines response to radio-and chemotherapy in childhood medulloblastoma (MB). Methods: We used DAOY and UW228 human MB cells engineered to stably express different levels of c-MYC, and tested whether c-MYC expression has an effect on radio-and chemosensitivity using the colorimetric 3-(4,5-dimethylthiazol- 2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium inner salt (MTS) assay, clonogenic survival, apoptosis assays, cell cycle analysis, and western blot assessment. In an effort to validate our results, we analyzed c-MYC mRNA expression in formalin-fixed paraffin-embedded tumor samples from well-documented patients with postoperative residual tumor and compared c-MYC mRNA expression with response to radio-and chemotherapy as examined by neuroradiological imaging. Results: In DAOY -and to a lesser extent in UW228 -cells expressing high levels of c-MYC, the cytotoxicity of cisplatin, and etoposide was significantly higher when compared with DAOY/UW228 cells expressing low levels of c-MYC. Irradiation-and chemotherapy-induced apoptotic cell death was enhanced in DAOY cells expressing high levels of c-MYC. The response of 62 of 66 residual tumors was evaluable and response to postoperative radio-(14 responders (CR, PR) vs. 5 non-responders (SD, PD)) or chemotherapy (23 CR/PR vs. 20 SD/PD) was assessed. c-MYC mRNA expression was similar in primary MB samples of responders and non-responders (Mann-Whitney U test, p = 0.50, ratio 0.49, 95% CI 0.008-30.0 and p = 0.67, ratio 1.8, 95% CI 0.14-23.5, respectively). Conclusions: c-MYC sensitizes MB cells to some anti-cancer treatments in vitro. As we failed to show evidence for such an effect on postoperative residual tumors when analyzed by imaging, additional investigations in xenografts and larger MB cohorts may help to define the exact function of c-MYC in modulating response to treatment.

A1 - Ernestus, Karen A1 - Beer, Meinrad T1 - Hit the mark with diffusion-weighted imaging: metastases of rhabdomyosarcoma to the extraocular eye muscles N2 - Background Rhabdomyosarcoma is the most frequent malignant intraorbital tumour in paediatric patients. Differentiation of tumour recurrence or metastases from post-therapeutic signal alteration can be challenging, using standard MR imaging techniques. Diffusion-weighted MRI (DWI) is increasingly considered a helpful supplementary imaging tool for differentiation of orbital masses. Case presentation We report on a 15-year-old female adolescent of Caucasian ethnicity who developed isolated bilateral thickening of extraocular eye muscles about two years after successful multimodal treatment of orbital alveolar rhabdomyosarcoma. Intramuscular restricted diffusion was the first diagnostic indicator suggestive of metastatic disease to the eye muscles. DWI subsequently showed signal changes consistent with tumour progression, complete remission under chemoradiotherapy and tumour recurrence. Conclusions Restricted diffusivity is a strong early indicator of malignancy in orbital tumours. DWI can be the key to correct diagnosis in unusual tumour manifestations and can provide additional diagnostic information beyond standard MRI and PET/CT. Diffusion-weighted MRI is useful for monitoring therapy response and for detecting tumour recurrence.

Twenty-two PwMS received six sessions of anodal (PwMS\(_{real}\), n = 12) or sham (PwMS\(_{sham}\), n = 10) tDCS to the cerebellum prior to performing the locomotor adaptation task on the SBT. To evaluate the effect of the intervention, functional gait assessment (FGA) scores and distance walked in 2 min (2MWT) were measured at the baseline (T0), day 6 (T5), and at the 4-week follow up (T6). Locomotor performance and changes of motor outcomes were similar in PwMS\(_{real}\) and PwMS\(_{sham}\) independently from tDCS mode applied to the cerebellum (anodal vs. sham, on FGA, p = 0.23; and 2MWT, p = 0.49). When the data were pooled across the groups to investigate the effects of multiple sessions of SBT training alone, significant improvement of gait and balance was found on T5 and T6, respectively, relative to baseline (FGA, p < 0.001 for both time points). The FGA change at T6 was significantly higher than at T5 (p = 0.01) underlining a long-lasting improvement. An improvement of the distance walked during the 2MWT was also observed on T5 and T6 relative to T0 (p = 0.002). Multiple sessions of SBT training resulted in a lasting improvement of gait stability and endurance, thus potentially reducing the risk of fall as measured by FGA and 2MWT. Application of cerebellar tDCS during SBT walking had no additional effect on locomotor outcomes.
