Latent fingermarks are the commonest type of fingermark encountered at crime scenes. The Fingermark Visualisation Manual provides crime scene practitioner's with sequential information regarding which enhancement processes are best suited for a range of deposition surfaces (Bandey et al., 2014) [1]. However, there are still many surfaces, such as painted walls where more knowledge is required regarding which development techniques provide optimum results. In this study, four paint types were tested (matt, silk, bathroom and eggshell). Fingermarks were deposited on painted simulated walls and aged for 1 day, 1 week and 1 month. Fingermarks were developed by three processes highlighted as the most frequently used by practitioners (magnetic granular powder, magneta flake powder and ninhydrin). The results showed that overall black magnetic granular powder outperformed both magneta flake powder and ninhydrin on all paint types. This contradicts current UK guidelines for enhancement of fingermarks on matt painted walls, as black magnetic granular powder is not a recommended process at present. SEM and SEM-EDX analysis showed distinct differences between matt paint and the three non-matt paints tested, which provides an explanation for the results obtained. Conservation of the three-dimensional aspect of bitemarks optimizes their analysis. Although bitemarks could be recorded with a surface scanner, in clinical dentistry, intraoral scanners are used as an alternative to conventional dental impressions. BEZ235 Here we assess the reproducibility and the reliability of a three-dimensional bitemark analysis protocol using an intraoral scanner. Twenty-seven volunteers bit on different materials dental wax, hard cheese, chocolate and apple. Then, bitemarks and dentitions were scanned with the PlanMeca® Emerald intraoral scanner and the scans obtained were exported into the mesh comparison software, CloudCompare®, which can generate overlays automatically. For this purpose, dentitions were aligned and compared with the indentations. The meshing and non-meshing areas were visualized using a colorimetric scale. First, the same blinded observer compared the bitten materials by analyzing 256 meshing areas for each. Secondly, comparisons of bitemarks from wax were analyzed in a randomized blinded study involving four observers (dentist, dental student, forensic scientist and police officer) and predictive values were calculated. The wax support obtained the best result and apple the worst. The rate of correct classifications was high and misclassification was rare. For the all observers, negative predictive values were near 100%. Positive predictive values were more variable. Moreover, the work clearly highlighted the importance of experience in odontology. AIMS To make recommendations on the indications for molecular testing regarding the diagnosis, prediction of prognosis, and treatment selection in adult patients with s oft tissue sarcomas (STS) excluding gastrointestinal stromal tumour. MATERIALS AND METHODS This guideline was developed by the Cancer Care Ontario's Program in Evidence-Based Care (PEBC) and the Sarcoma Disease Site Group (DSG). The medline, embase, and Cochrane Library databases, main guideline websites, abstracts of relevant annual meetings, and PROSPERO databases were searched (January 2005 to October 2016). Internal and external reviews were conducted, with final approval by the PEBC and the Sarcoma DSG. RESULTS Based on the available evidence, we made three S trong Recommendations, 14 Recommendations, 9 Qualified Statements, and seven No Recommendations. The three Strong Recommendations include i) MDM2 amplification by fluorescence in situ hybridization (FISH) is recommended as a sensitive and specific test to differentiate patients with atypical lipomatous tumour/well-differentiated liposarcoma, or dedifferentiated liposarcoma from lipoma or other STS in the differential diagnosis; ii) SS18 (SYT) break-apart by FISH or SS18-SSX (SYT-SSX) fusion by reverse transcription-polymerase chain reaction is recommended as a sensitive and specific test to differentiate patients with synovial sarcoma from other sarcomas; iii) CTNNB1 S45F mutation by polymerase chain reaction is recommended as a prognostic factor for poor recurrence-free survival in patients with desmoid tumours. CONCLUSION This guideline may serve as a framework for the thoughtful implementation of molecular studies at cancer centres and other jurisdictions. Some of the recommendations may need to be updated when new evidence appears in the future. Liquid biopsies (LB) are emerging in the oncology field, with promising data as new diagnostic, prognostic and treatment-monitoring tools. Squamous cell carcinoma of the head and neck (SCCHN) is a heterogenous disease and many challenges remain to improve patient outcomes. Liquid biopsy could be of interest at different stages of SCCHN disease, including better screening to diagnose more patients at an early stage, early detection of relapse after curative treatment, and the implementation of precision medicine. As LB is very attractive by the ease of sampling, this field is moving fast. Therefore, it is important to be aware of the potential applications but also the limitations of these new tools in regards to technical aspects and interpretation of the data. In this review, we will first give an overview of potential clinical applications and technical challenges of circulating tumor DNA (ctDNA) and then focus on current available data of ctDNA in SCCHN. Although the literature on ctDNA analysis for SCCHN is scarce compared to other tumors, preliminary results seem to hold promise for the future, including the detection of minimal residual disease or the detection of potentially targetable events through liquid biopsy. Prospective liquid-biopsy driven clinical trials are needed to validate its clinical relevance. STUDY OBJECTIVE To investigate the effective analgesia for video-assisted thoracic surgery. DESIGN In this prospective non-inferiority study, we evaluated the postoperative analgesic effect of preoperative ultrasound-guided Erector Spinae Plane blocks (ESPB) on T4 and T6 levels in patients undergoing video-assisted thoracic surgery in comparison with paravertebral block (PVB) at the same intervertebral spaces. SETTING A university hospital. PATIENTS 66 patients scheduled to undergo video-assisted thoracic surgery under general anesthesia were included. INTERVENTIONS Patients were randomly allocated to receive ultrasound-guided ESP blocks on T4 and T6 levels (Group ESPB, n = 33) or PVB (Group PVB, n = 33) with 30 mL 0.4% ropivacaine 30 min before anesthesia induction. A continuous flurbiprofen (8 mg/h) was infused postoperatively through a single-use infusion device and intravenous oxycodone supplied as analgesic rescue if needed, with bolus of oxycodone (1 mg) and lockout time being 10 min. MEASUREMENTS The primary outcome was the postoperative oxycodone consumption at 48 h.
