PURPOSE: Minimally invasive surgery is in constant further development and has replaced many conventional operative procedures. If vascular structure movement could be detected during these procedures, it could reduce the risk of vascular injury and conversion to open surgery. The recently proposed motion-amplifying algorithm Eulerian Video Magnification (EVM) has been shown to substantially enhance minimal object changes in digitally recorded video that is barely perceptible to the human eye...

STUDY TYPE: A cross sectional survey. BACKGROUND: Global estimates indicate that by 2018 2.3 billion individuals worldwide will suffer from lower urinary tract symptoms (LUTS), with 1.1 billion having LUTS related to bladder outlet obstruction (BOO). Left untreated BOO in men causes irreversible changes to the urinary tract leading to urinary retention, the need for catheterization, renal failure and even death. Estimates suggest that Africa will be one of the continents with the greatest increase in (LUTS) by 2018 however direct measures in Africa are lacking...

Diagnosis of tattoo complications is a multi-facetted field since many clinical entities and disease mechanisms are represented. Infections, allergies, and pigment foreign body reactions with granuloma are the major groups. The clinician needs a structured approach to diagnosis and an armamentarium of standard tests. Diagnosis primarily builds on patient history, objective clinical examination, and punch biopsy, supplemented with microbiology testing, ultrasound scanning, and clinical photography. Evaluation of allergic tattoo reactions and allergy to pigments by patch testing is not applicable and has a falsely negative outcome except for the diagnosis of allergy to metals and preservatives...

BACKGROUND: Point-of-care-ultrasound (POCUS) is an increasingly important tool for emergency physicians and has become a standard component of emergency medicine residency training in high-income countries. Cardiopulmonary ultrasound (CPUS) is emerging as an effective way to quickly and accurately assess patients who present to the emergency department with shock and dyspnea. Use of POCUS, including CPUS, is also becoming more prevalent in low- and middle-income countries (LMICs); however, formal ultrasound training for emergency medicine resident physicians in these settings is not widely available...

BACKGROUND: It remains unclear which item format would best suit the assessment of clinical reasoning: context-rich single best answer questions (crSBAs) or key-feature problems (KFPs). This study compared KFPs and crSBAs with respect to students' acceptance, their educational impact, and psychometric characteristics when used in a summative end-of-clinical-clerkship pediatric exam. METHODS: Fifth-year medical students (n = 377) took a computer-based exam that included 6-9 KFPs and 9-20 crSBAs which assessed their clinical reasoning skills, in addition to an objective structured clinical exam (OSCE) that assessed their clinical skills...
