Abstract
Large-scale monitoring schemes are essential in assessing global mammalian biodiversity, and in this framework, leeches have recently been promoted as an indirect source of DNA from terrestrial mammal species. Carrion feeding flies are ubiquitous and can be expected to feed on many vertebrate carcasses. Hence, we tested whether fly-derived DNA analysis may also serve as a novel tool for mammalian diversity surveys. We screened DNA extracted from 201 carrion flies collected in tropical habitats of Côte d'Ivoire and Madagascar for mammal DNA using multiple PCR systems and retrieved DNA sequences from a diverse set of species (22 in Côte d'Ivoire, four in Madagascar) exploiting distinct forest strata and displaying a broad range of body sizes. Deep sequencing of amplicons generated from pools of flies performed equally well as individual sequencing approaches. We conclude that the analysis of fly-derived DNA can be implemented in a very rapid and cost-effective manner and will give a relatively unbiased picture of local mammal diversity. Carrion flies therefore represent an extraordinary and thus far unexploited resource of mammal DNA, which will probably prove useful for future inventories of wild mammal communities.

Abstract
UNLABELLED HISTORY AND CLINICAL SYMPTOMS: A 58-year-old man was admitted to our hospital with acute chest pain and subfebrile temperatures. Two years ago, endovascular aortic stent-graft placement had been performed for acute type B aortic dissection complicated by malperfusion syndrome. DIAGNOSTIC ASSESSMENT CT angiography showed a discrete soft-tissue attenuation mass between the aorta and esophagus. The patient developed progressive swallow disorder and esophago-gastro-duodenoscopy demonstrated deep esophageal ulcerations at the level of the implanted aortic stent-graft. Intravenous treatment with broad spectrum antibiotics was started. The FDG-PET/CT scan showed increased FDG uptake and air entrapment in the affected region establishing the diagnosis of aortoesophageal fistula formation. THERAPY AND OUTCOME Given the generally poor condition of the patient and the high risk of any aggressive surgical intervention, a new limited surgical approach was chosen consisting of open transthoracic esophageal resection, blind closure of the stomach and cervical esophagostomy. A percutaneous endoscopic gastrostomy tube was placed. After three months, esophageal continuity was restored by retrosternal colon interposition. The presented therapeutic management resulted in a full recovery of the patient. CONCLUSION Aortoesophageal fistula is a rare complication of thoracic aortic stent-graft placement. Patient may present with unspecific symptoms such as fever and rised inflammatory markers, but may also present with massive upper gastrointestinal bleeding. The herein presented limited therapy with esophageal resection represents a promising to the otherwise difficult therapy of aortoesophageal fistula.

Abstract
OBJECTIVES The superiority of left internal thoracic artery (LITA) grafting to the left anterior descending artery (LAD) is well established. Patency rates of 80%-90% have been reported at 10-year follow-up. However, the superiority of sequential LITA grafting has not been proven. Our aim was to compare patency rates after sequential LITA grafting to a diagonal branch and the LAD with patency rates of LITA grafting to the LAD and separate vein grafting to a diagonal branch. METHODS A total of 58 coronary artery bypass graft (CABG) patients, operated on between 01/2000 and 12/2002, underwent multi-slice computed tomography (MSCT) between 2006 and 2008. Of these patients, 29 had undergone sequential LITA grafting to a diagonal branch and to the LAD ("Sequential" Group), while in 29 the LAD and a diagonal branch were separately grafted with LITA and vein ("Separate" Group). Patencies of all anastomoses were investigated. RESULTS Mean follow-up was 1958±208 days. The patency rate of the LAD anastomosis was 100% in the Sequential Group and 93% in the Separate Group (p=0.04). The patency rate of the diagonal branch anastomosis was 100% in the Sequential Group and 89% in the Separate Group (p=0.04). Mean intraoperative flow on LITA graft was not different between groups (69±8ml/min in the Sequential Group and 68±9ml/min in the Separate Group, p=n.s.). CONCLUSION Patency rates of both the LAD and the diagonal branch anastomoses were higher after sequential arterial grafting compared with separate arterial and venous grafting at 5-year follow-up. This indicates that, with regard to the antero-lateral wall of the left ventricle, there is an advantage to sequential arterial grafting compared with separate arterial and venous grafting.

Abstract
PURPOSE Traumatic injury of supra-aortic vessels remains a challenge in the initial diagnostics of severely injured patients. The presented prospective study analyzed the impact of multislice computed tomography angiography (CTA) as the primary diagnostic method. METHODS Patients with the following criteria were included and screened for a dissection of the supra-aortic vessels: a) admission directly from the scene, b) resuscitation room treatment indicated by the official criteria of the DGU (German Society for the Surgery of Trauma), c) suspected blunt trauma to head or trunk as well as d) age over 16 years. RESULTS During a period of 18 months 374 patients were treated for blunt trauma in the resuscitation room. In 176 cases CTA of the supra-aortic vessels was performed and pathological findings were observed in 16 patients. In 4 cases (2%) a traumatic dissection of supra-aortal vessels was diagnosed and confirmed by magnetic resonance imaging (MRI). All patients received heparin in a PTT effective dosage for 2 weeks and after rehabilitation there were no neurologic deficits. CONCLUSION Traumatic supra-aortic dissection was found in 2% of cases in the presented study group. The mechanisms of injury were not distinct in this group. Essentially MSCT angiography screening was demonstrated to be a safe diagnostic tool.

Abstract
An accessory liver is a rare developmental anomaly. There are two subtypes: the accessory liver lobe (ALL), which is connected to the liver and the true ectopic liver. An accessory liver is usually of no clinical relevance in spite of the very rare cases in which torsion or other complications may cause serious problems. This anomaly should not be misinterpreted as a malignant tumour. We report the case of an accessory liver lobe, located below the left diaphragm, which was misdiagnosed as a metastasis of a known malignant melanoma. The diagnosis ALL was established by a biopsy under guidance of magnetic resonance tomography (MRT). In our opinion, an accessory liver and its appearance should be known, to include this entity in differential diagnosis of perihepatic masses.

Abstract
Commercial hunting and habitat loss are major drivers of the rapid decline of great apes [1]. Ecotourism and research have been widely promoted as a means of providing alternative value for apes and their habitats [2]. However, close contact between humans and habituated apes during ape tourism and research has raised concerns that disease transmission risks might outweigh benefits [3-7]. To date only bacterial and parasitic infections of typically low virulence have been shown to move from humans to wild apes [8, 9]. Here, we present the first direct evidence of virus transmission from humans to wild apes. Tissue samples from habituated chimpanzees that died during three respiratory-disease outbreaks at our research site, Côte d'Ivoire, contained two common human paramyxoviruses. Viral strains sampled from chimpanzees were closely related to strains circulating in contemporaneous, worldwide human epidemics. Twenty-four years of mortality data from observed chimpanzees reveal that such respiratory outbreaks could have a long history. In contrast, survey data show that research presence has had a strong positive effect in suppressing poaching around the research site. These observations illustrate the challenge of maximizing the benefit of research and tourism to great apes while minimizing the negative side effects.

Abstract
UNLABELLED We investigated the efficacy of combined FDG-PET/CT imaging for the diagnosis of small-size uveal melanomas and the feasibility of combining separate, high-resolution (HR) FDG-PET with MRI for its improved localization and detection. PATIENTS, METHODS 3 patients with small-size uveal melanomas (0.2-1.5 ml) were imaged on a combined whole-body PET/CT, a HR brain-PET, and a 1.5 T MRI. Static, contrast-enhanced FDG-PET/CT imaging was performed of head and torso with CT contrast enhancement. HR PET imaging was performed in dynamic mode 0-180 min post-injection of FDG. MRI imaging was performed using a high-resolution small-loop-coil placed over the eye in question with T2-3D-TSE and T1-3D-SE with 18 ml Gd-contrast. Patients had their eyes shaded during the scans. Lesion visibility on high-resolution FDG-PET images was graded for confidence: 1: none, 2: suggestive, 3: clear. Mean tumour activity was calculated for summed image frames that resulted in confidence grades 2 and 3. Whole-body FDG-PET/CT images were reviewed for lesions. PET-MRI and PET/CT-MRI images of the head were co-registered for potentially improved lesion delineation. RESULTS Whole-body FDG-PET/CT images of 3/3 patients were positive for uveal melanomas and negative for disseminated disease. HR FDG-PET was positive already in the early time frames. One patient exhibited rising tumour activity with increasing uptake time on FDG-PET. MRI images of the eye were co-registered successfully to FDG-PET/CT using a manual alignment approach. CONCLUSIONS Small-size uveal melanomas can be detected with whole-body FDG-PET/CT. This feasibility study suggests the exploration of HR FDG-PET in order to provide additional diagnostic information on patients with uveal melanomas. First results support extended uptake times and high-sensitivity PET for improved tumour visibility. MRI/PET co-registration is feasible and provides correlated functional and anatomical information that may support alternative therapy regimens.
