007). CONCLUSIONS adding mass to the lower limbs of runners with a TTA increased metabolic power by more than what has been reported for those without an amputation. We found no effect of added mass on biomechanical asymmetry, but the affected leg had consistently shorter swing times than the unaffected leg. This suggests that individuals with a TTA maintain asymmetries despite changes in RSP mass and that lightweight prostheses could improve performance by minimizing metabolic power without affecting asymmetry.A unique and novel μ-thin-layer chromatography method based on Sn(II) ion-imprinted polymer (Sn-IIP) for speciation of tin ion species in water and plasma samples is introduced for the first time. For this purpose, N-allylthiourea (NATU) and ethylene glycol dimethacrylate (EGDMA) were copolymerized in the presence of Sn(II). The obtained polymer particles were identified using multiple techniques like BET, FT-IR, XRD, and FESEM. The effects of different variables such as pH of the solution, mobile phase composition, and IIP per CaSO4 mass ratio on the separation efficiency were also evaluated. After completion of the separation process on the plate, its surface was scanned by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Under the established optimal condition, the detection limit, relative standard deviation (RSD) of responses, and linear dynamic range (LDR) of the method were obtained as 0.3 μg L-1, 3.5%, and 0.8-900 μg L-1 for Sn(II) and 0.4 μg L-1, 4%, and 1-740 μg L-1 for Sn(IV) assay, respectively. The developed method was finally applied to the speciation of tin in various water and plasma samples.

The aim of this study was to evaluate the knowledge of dealing with and treatment of patients as victims of terrorist attacks of 5th year medical students at the Mannheim Medical Faculty of Heidelberg University prior to and after a specific seminar. METHODS All students offered to participate voluntarily. Before the seminar a questionnaire with six questions about previous knowledge on terror awareness was distributed. After the seminar another almost identical questionnaire with six questions was distributed and completed by the students. RESULTS A total of 97 medical students agreed to take part in the study of whom 53 were female. The mean age was 25.4 years (SD 2.75 years). After the seminar the students wanted to statistically significantly intensify the topic and believed that hospitals should be prepared for the treatment of victims of terrorism. CONCLUSION With the seminar "Military Medicine", which was held as part of the Mannheim reformed curriculum of medicine (MaReCuM plus) in the 5th year, the interest of medical students could be significantly increased. This study could show for the first time that terrorist attacks and the resulting injuries have significant relevance for medical students. Consideration of this topic in all medical school curricula would be justified.This article reports a case of medial dislocation of the talus as a rare injury caused by a fall from a low height.Treatment recommendations given in the literature for this rare injury are heterogeneous but closed reduction is predominant. Little is known about possible obstacles in closed reduction. The known complications include posttraumatic arthritis and necrosis of the talus.A posttraumatic lesion of the tibial nerve has not been reported, which is why a treatment recommendation is illustrated and discussed based on this case report.BACKGROUND Separation of the pubic symphysis with corresponding diastasis can be stabilized by symphyseal plating. OBJECTIVE Which pelvic injuries are stabilized with symphyseal plating and what is their outcome? MATERIAL AND METHODS A retrospective evaluation of 64 patients who underwent symphyseal plating over a period of 24 months was conducted. RESULTS Of the patients 56 were male and 8 female with a mean age of 44 years (SD ± 17 years). The main cause of the pelvic injuries were traffic accidents. The distribution according to the AO fracture classification was 14 × B1, 10 × B2, 5 × B3, 23 × C1, 9 × C2 and 3 × C3 injuries. The distribution according to the Young and Burgess classification showed 9 × APC I, 18 × APC II, 13 × APC III, 9 × LC I, 3 × LC II, 2 × LC III and 10 × VS injuries. The mean Injury Severity Score (ISS) was 32 (SD ± 17) and the mean inpatient stay was 29 days (SD ± 16 days; positive correlation p ≤ 0.001). Radiological implant loosening occurred in 52 patients. 14 patients required treatment for severe complications.  https://www.selleckchem.com/products/mitomycin-c.html  The leading reason for revision surgery was implant failure (n = 8). CONCLUSION These observations suggest that radiological signs of implant loosening are commonly observed but rarely the reason for revision surgery. Complete implant failures, however; occur mainly within the first postoperative weeks and require early revision. A timely clarification by additional X-ray imaging should be carried out if this is suspected.In view of the increasing violence and aggression against medical personnel in healthcare facilities, there are considerations by the legislature to punish violent offenders in hospitals more severely. Hospital and emergency room staff are increasingly confronted by physically and psychologically violent patients or their relatives. Sometimes medical treatment in a hospital or emergency room is an exceptional physical or mental situation for many patients and their relatives. In addition, the consumption of alcohol and drugs, long waiting times, psychiatric illnesses and dissatisfaction with medical care or communication problems are considered to be the cause of violence against medical personnel in healthcare facilities. In addition to the physical consequences for the affected employees, the psychological consequences, such as job dissatisfaction, fear of work and posttraumatic stress disorder also pose major challenges for the employer. In order to fulfil the obligation of care towards employees, the latter should provide concepts for protection against violence as part of the company health management.
