An improvement of the human walk seems to be possible through karate and fitness training, even under dual-task conditions. A prolonged intervention time with multiple repetitions of gait analysis could give better evidence if karate is a useful tool to increase fall prevention.

Background Some of the advantages of implementing electronic emergency department information systems (EDIS) are improvements in data availability and simplification of statistical evaluations of emergency department (ED) treatments. However, for multi-center evaluations, standardized documentation is necessary. The AKTIN project (“National Emergency Department Register: Improvement of Health Services Research in Acute Medicine in Germany”) has used the “German Emergency Department Medical Record” (GEDMR) published by the German Interdisciplinary Association of Intensive and Emergency Care as the documentation standard for its national data registry. Methods Until March 2016 the documentation standard in ED was the pen-and-paper version of the GEDMR. In April 2016 we implemented the GEDMR in a timeline-based EDIS. Related to this, we compared the availability of structured treatment information of traumatological patients between pen-and-paper-based and electronic documentation, with special focus on the treatment time. Results All 796 data fields of the 6 modules (basic data, severe trauma, patient surveillance, anesthesia, council, neurology) were adapted for use with the existing EDIS configuration by a physician working regularly in the ED. Electronic implementation increased availability of structured anamnesis and treatment information. However, treatment time was increased in electronic documentation both immediately (2:12 ± 0:04 h; n = 2907) and 6 months after implementation (2:18 ± 0:03 h; n = 4778) compared to the pen-and-paper group (1:43 ± 0:02 h; n = 2523; p < 0.001). Conclusions We successfully implemented standardized documentation in an EDIS. The availability of structured treatment information was improved, but treatment time was also increased. Thus, further work is necessary to improve input time.

No clinical standard procedure has yet been defined to quantify the vascular pattern of vocal folds. Subjective classification trials have shown a lot of promise. Narrow band imaging (NBI) as an endoscopic imaging tool is useful, because it shows the vascular structure clearer than white light endoscopy (WL) alone. Endoscopic images of 74 human vocal folds (NBI and WL) were semi-automatically evaluated after image processing with respect to pixels of vessels and mucosa by the software MeVisLab. The ratios of vessel/mucosa pixels were compared. Using NBI, more vocal fold vessels are visible compared with WL alone (p = 0.000). There may be a difference between the right and left vocal folds due to the handedness of the examiner (p = 0.033) without any interaction between the method (NBI/WL) and the side (right/left) (p = 0.467). MeVisLab is a suitable tool for the objective quantification of the vessel/mucosa ratio for NBI and WL endoscopic images. NBI is an appropriate endoscopic tool for examination of diseases of vocal folds with changes in the vascular pattern. There is evidence that the handedness of the examiner may have an influence on the quality of the examination between the right and left vocal folds.
