Abstract
INTRODUCTION Current treatment of spinal metastases (SM) aims on preserving spinal stability, neurological status, and functional status as well as achieving local control. It consists of spinal surgery followed by radiotherapy and/or systemic treatment. Adjuvant therapy usually starts with a delay of a few weeks to prevent wound healing issues. Intraoperative radiotherapy (IORT) has previously been successfully applied during brain tumor, breast and colorectal carcinoma surgery but not in SM, including unstable one, to date. In our case series, we describe the feasibility, morbidity and mortality of a novel treatment protocol for SM combining stabilization surgery with IORT. METHODS Single center case series on patients with SM. Single session stabilization by navigated open or percutaneous procedure using a carbon screw-rod system followed by concurrent 50 kV photon-IORT (ZEISS Intrabeam). The IORT probe is placed via a guide canula using navigation, positioning is controlled by IOCT or 3D-fluroscopy enabling RT isodose planning in the OR. RESULTS 15 (8 female) patients (71 ± 10y) received this treatment between 07/22 and 09/23. Median Spinal Neoplastic Instability Score was 8 [7-10] IQR. Most metastasis were located in the thoracic (n = 11, 73.3%) and the rest in the lumbar (n = 4, 26.7%) spine. 9 (60%) patients received open, 5 (33%) percutaneous stabilization and 1 (7%) decompression only. Mean length of surgery was 157 ± 45 min. Eleven patients had 8 and 3 had 4 screws placed. In 2 patients radiotherapy was not completed due to bending of the guide canula with consecutive abortion of IORT. All other patients received 8 Gy isodoses at mdn. 1.5 cm [1.1-1.9, IQR] depth during 2-6 min. The patients had Epidural Spinal Cord Compression score 1a-3. Seven patients (46.7%) experienced adverse events including 2 surgical site infection (one 65 days after surgery). CONCLUSION 50 kV photon IORT for SM and consecutive unstable spine needing surgical intervention is safe and feasible and can be a promising technique in selected cases.

Abstract
Introduction Directional Leads (dLeads) represent a new technical tool in Deep Brain Stimulation (DBS), and a rapidly growing population of patients receive dLeads. Research question The European Association of Neurosurgical Societies(EANS) functional neurosurgery Task Force on dLeads conducted a survey of DBS specialists in Europe to evaluate their use, applications, advantages, and disadvantages. Material and methods EANS functional neurosurgery and European Society for Stereotactic and Functional Neurosurgery (ESSFN) members were asked to complete an online survey with 50 multiple-choice and open questions on their use of dLeads in clinical practice. Results Forty-nine respondents from 16 countries participated in the survey (n = 38 neurosurgeons, n = 8 neurologists, n = 3 DBS nurses). Five had not used dLeads. All users reported that dLeads provided an advantage (n = 23 minor, n = 21 major). Most surgeons (n = 35) stated that trajectory planning does not differ when implanting dLeads or conventional leads. Most respondents selected dLeads for the ability to optimize stimulation parameters (n = 41). However, the majority (n = 24), regarded time-consuming programming as the main disadvantage of this technology. Innovations that were highly valued by most participants included full 3T MRI compatibility, remote programming, and closed loop technology. Discussion and conclusion Directional leads are widely used by European DBS specialists. Despite challenges with programming time, users report that dLeads have had a positive impact and maintain an optimistic view of future technological advances.

Abstract
BACKGROUND There is only limited data on the management of cerebrospinal fluid (CSF) fistulas after cervical endoscopic spine surgery. We investigated the current literature for treatment options and present a case of a patient who was treated with CT-guided epidural fibrin patch. METHODS We present the case of a 47-year-old female patient with a suspected CSF fistula after endoscopic decompression for C7 foraminal stenosis. She was readmitted 8 days after surgery with dysesthesia in both upper extremities, orthostatic headache and neck pain, which worsened during mobilization. A CSF leak was suspected on spinal magnetic resonance imaging. A computer tomography (CT)-guided epidural blood patch was performed with short-term relief. A second CT-guided epidural fibrin patch was executed and the patient improved thereafter and was discharged at home without sensorimotor deficits or sequelae. We investigated the current literature for complications after endoscopic spine surgery and for treatment of postoperative CSF fistulas. RESULTS Although endoscopic and open revision surgery with dura repair were described in previous studies, dural tears in endoscopic surgery are frequently treated conservatively. In our case, the patient was severely impaired by a persistent CSF fistula. We opted for a less invasive treatment and performed a CT-guided fibrin patch which resulted in a complete resolution of patient's symptoms. DISCUSSION AND CONCLUSION CSF fistulas after cervical endoscopic spine procedures are rare complications. Conservative treatment or revision surgery are the standard of care. CT-guided epidural fibrin patch was an efficient and less invasive option in our case.

Abstract
Hintergrund Tinnitus betrifft ca. 15 % der Bevölkerung, jedoch existiert noch immer kein echtes Heilverfahren. Ein von uns entwickeltes neuartiges Erklärungsmodell erlaubt nun die Erprobung einer gezielten, an den Ursachen der Tinnitusentstehung ansetzenden Behandlung. Diese basiert auf stochastischen Resonanzphänomenen an bestimmten synaptischen Verbindungen im Hörsystem, welche gezielt durch extern zugeführtes schwellennahes Rauschen induziert werden sollen. Fragestellung Die vorliegende Pilotstudie soll zeigen, ob ein spektral individuell angepasstes Rauschen erfolgreich chronischen tonalen/schmalbandigen Tinnitus während der Stimulation abschwächen kann. Material und Methoden Bei 22 volljährigen Tinnituspatienten (46.6±16.3 Jahre; 4 Frauen) wurden Hörverlust (HV) sowie Tinnitusfrequenzen (TF) und -lautstärken (TL) audiometrisch bestimmt. Darauf basierend wurden bis zu 8 verschiedene Rauschstimuli (RS) mit je 5 Lautstärken (−20 bis +20 dB SL) erzeugt. Diese wurden über audiologische Kopfhörer in einer Schallkammer für jeweils 40 s präsentiert. Nach jeder Präsentation wurde mithilfe einer 5‑stufigen Bewertungsskala (−2 bis +2) ermittelt, ob sich die TL verändert hat. Ergebnisse Es fanden sich Patienten ohne Verbesserung der TL (n = 6) und solche mit Verbesserung (n = 16), wobei hier RS um die TF besonders effektiv waren. Die Gruppen zeigten post hoc deutliche Unterschiede in den Audiogrammen: Offenbar ist das hier getestete Verfahren insbesondere bei normalhörenden Tinnituspatienten und solchen mit geringgradigem HV effektiv. Schlussfolgerung Die subjektiv wahrgenommene TL war bei 16 von 22 Probanden für die Dauer der Stimulation reduziert. Für den möglichen Erfolg einer zukünftigen Therapie scheint der HV relevant zu sein.

Abstract
Chainsaw accidents are severe injuries, mostly work-related and concerning upper or lower extremities. Few suicidal chainsaw injuries are reported, all of them fatal. We report the case of a 23-year-old man who attempted suicide by sub-decapitation with a chainsaw, its successful (peri-) operative management, and clinical course along with a discussion of the contemporary management and body of evidence of such lesions. Chainsaw injuries are severe traumas. Stepwise surgery with maximal functional reconstruction is safe and optimal clinical outcome can be achieved.

Abstract
Introduction Several scoring systems have been developed to predict postoperative mortality and complications in patients undergoing cardiac surgery. However, these computer-based calculations are time- and cost-intensive. A simple but highly predictive test for postoperative risk would be of clinical benefit with respect to increasingly scarce hospital resources. We therefore assessed the predictive power of fibroblast growth factor 23 (FGF23) measurement compared with an established scoring system. Methods We conducted a prospective interdisciplinary observational study at the Saarland University Medical Centre that included 859 patients undergoing elective cardiac surgery between January 2010 and March 2011 with a median follow-up after discharge of 822 days. We compared a single preoperative measurement of FGF23 as a prognostic tool with the 18 parameters comprising EuroSCORE II with respect to postoperative mortality, acute kidney injury, non-occlusive mesenteric ischemia, clinical course and long-term outcome. Results Preoperative FGF23 levels were highly predictive of postoperative outcome and complications. The predictive value of FGF23 for mortality in the receiver operating characteristic curve was greater than the EuroSCORE II (area under the curve: 0.800 versus 0.725). Moreover, preoperative FGF23 independently predicted postoperative acute kidney injury and non-occlusive mesenteric ischemia comparably to the EuroSCORE II. Finally, FGF23 was found to be an independent predictor of clinical course parameters, including duration of surgery, ventilation time and length of stay. Conclusions In patients undergoing elective cardiac surgery, a simple preoperative FGF23 measurement is a powerful indicator of surgical mortality, postoperative complications and long-term outcome. Its utility compares to the widely used EuroSCORE II.

Abstract
The level of polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans (PCDD/F), polychlorinated biphenyls (PCB) and polycondensated aromatic hydrocarbons (PAH) in compost of different degree of maturation from 21 Brazilian municipal solid waste (MSW) compositing plants has been evaluated. The study shows that most PCDD/F concentrations are above the levels acceptable in Baden-Württemberg (FRG), being 17 ng I-TE/kg, especially for compost from metropolitan areas. These results are similar to those found for Germany. For PCB, the average of the sum of the concentrations of the six congeners PCB 28, 52, 101, 138, 153 and 180 is about 3 times lower in relation to German samples being less than the value indicated by the Baden-Württemberg legislation (0.2 mg/kg).

Abstract
To assess the possible role of nicotinergic control in nociception and pain, experiments were carried out on rats under urethane anesthesia in which nociceptive activity was elicited by electrical stimulation of afferent C fibers in the sural nerve and recorded from single neurones in the thalamus and from ascending axons in the spinal cord. Intravenous administration of nicotine (0.01-0.5 mg/kg) depressed the nociceptive activity evoked in the thalamus and the spinal cord in a dose-dependent way. The maximum depression in thalamus and spinal cord was 40% of control activity and obtained at a dose of 0.025 mg/kg. Likewise, local administration of nicotine to the spinal cord by intrathecal injection (5, 10, and 30 micrograms) reduced the nociceptive activity evoked in neurones of the thalamus and in ascending axons of the spinal cord, the maximum of the depression being 40% of control activity. The depressant effect of nicotine (0.05 mg/kg) was reduced by mecamylamine (1 mg/kg) but not by atropine (0.5 mg/kg). It is concluded that the antinociceptive effect of nicotine is due to a specific action of the alcaloid at the spinal level.
