Machine vision tools are applied for determination of movement frequency or trajectory.

The searching for artefacts in video sequences is realized to find objects which can cause false detection of cilia's movement. The motion in video sequence can be generated by cilia of respiratory epithelium as well as by some artefacts, e.g. red blood cells, air bubbles or dead cells of the respiratory epithelium. Removal of artefacts causing false detections of movement is an important task when the motion area is evaluated. This article deals with the procedures and methods which enable searching and removing such artefacts that may cause incorrect detection of moving area. The effectiveness of pattern matching for artefacts detections in four most typical videos is finally compared and evaluated in results paragraph.

The article deals with measurement and analysis of kinetic parameters of human respiratory epithelium. The article shows possibilities of data acquisition (videosequences) and postprocessing using virtual instrumentation – LabVIEW. The designed methods enable analysis and measurement of two parameters: cilia beat frequency (CBF) and trajectory of cilia of respiratory epithelium. The problem task is divided into videosequence acquisition of cilia from the microscope, region of interest (ROI) selection for analyzed data reduction, preprocessing of reduced sequences. Frequency analysis is done by intensity method, which records and evaluates intensity variations in ROI. Trajectory analysis uses sophisticated algorithms of object detection in the image called pattern matching. Results of this work are used for diagnostics of some pathology of respiratory apparatus and epithelium. All solution steps are realized in LabVIEW development system.

The accuracy of slow motion cinematic analysis depends on frame rate of used camera. Specific case of cinematic analysis is in medical research focusing on microscopic objects (cilia of respiratory epithelium). Higher frame rate of camera (400 fps e.g.) causes that exposure time for camera sensor is too short, so it is necessary to use lightning source with higher optical (illuminating) efficiency and higher reliability. Hardware conditions are also limited by used light microscope. Paper focuses on design of LED illumination modules, their control, modes and supplying circuits for high speed imaging purposes.

Abstract 4900 Recent advances in the treatment of multiple myeloma have increased response rates and treatment outcomes and raised hopes that myeloma may soon be turned into a chronic disease. However, myeloma treatment is often associated with various side effects that can sometimes have a significant impact on the quality of life of myeloma patients and also affect the overall treatment plan. An international comparative survey of myeloma patients and patient relatives and healthcare professionals is conducted to assess perceptions of how myeloma patients are informed about potential side effects of myeloma treatment options, the impact of treatment side effects on a myeloma patient's overall well-being and on the course of myeloma treatment, the satisfaction concerning the management of treatment side effects, potential side effects that myeloma patients don't feel comfortable reporting to their doctor as well as potential reasons for not reporting them, and the satisfaction concerning access to information and support, access to novel treatments, coverage of treatment costs, overall quality of treatment and care, and psycho-social and emotional support. The comparative survey is conducted based on 2 comparable two-page questionnaires, 1 for healthcare professionals and 1 for myeloma patients and patient relatives. The survey consists of 9 multiple-choice and ranking format questions. The questionnaires were developed by ME. They were pre-tested with both professional and patient communities and are available in 6 languages: DE, EN, ES, FR, IT, PL. The survey is distributed by mail or e-mail, it can be taken online via accessing the organisation's web site, and it is conducted on paper at haematological and oncological congresses and patient information days. To date, a total of 272 healthcare professionals from 44 countries and 257 myeloma patients and patient relatives from 21 countries have responded to the survey. Data gathering will continue until mid OCT 2009 and final survey results will be presented at ASH 2009. The survey was made possible through an unrestricted grant from Ortho Biotech, Biopharmaceutical Division of Janssen-Cilag. Disclosures No relevant conflicts of interest to declare.

Abstract 4907 Patients who follow all the instructions about a course of treatment as directed by their doctor or nurse can be described as ‘compliant’ with a treatment plan. It is well-understood that failure of patients to follow treatment plans or understand the requirements after leaving their care could result in poor treatment outcomes, compounding health problems and additional health care costs. An international comparative survey of myeloma patients and patient relatives and healthcare professionals is conducted to assess perceptions of how myeloma treatment plans are determined, the familiarity of myeloma patients with their treatment plan, the satisfaction concerning the level of treatment compliance-related information, the factors that might have a negative effect on treatment compliance, the effect of one exemplary treatment side effect (peripheral neuropathy) on treatment compliance, and overall myeloma treatment compliance. The goal of the survey is to help patient and medical communities recognise the importance of patient compliance and the issues and challenges patients face in complying with their treatment. Learnings from the survey will be used to help improve myeloma patient compliance. The comparative survey is conducted based on 2 comparable two-page questionnaires, 1 for healthcare professionals and 1 for myeloma patients and patient relatives. The survey consists of 9 multiple-choice and ranking format questions. The questionnaires were developed by ME. They were pre-tested with both professional and patient communities and are available in 6 languages: DE, EN, ES, FR, IT, TR. The survey is distributed by mail or e-mail, it can be taken online through accessing the organisation's web site, and it is conducted on paper at haematological and oncological congresses and patient information days.
