ABSTRACT This is the first report of an evaluation of the use of a laser Doppler imager (LDI) scanner in the assessment of burn depth in patients. It is based on a 6-month, prospective audit of 76 burns of intermediate depth. Clinical and LDI assessments of burn wound depth were recorded at 48-72 h post-injury. Histological confirmation of depth was obtained from those burns requiring surgery. A healing time of less than 21 days was taken as confirmation of the injury being an superficial dermal burn. The accuracy of LDI in the assessment of burn depth was 97%, compared with 60-80% for established clinical methods. This audit confirms that LDI is a very accurate measurement tool for the assessment of burn wound depth. We recommend that all burns of intermediate depth should be analysed in this way in order to ensure appropriate management of the burn, to avoid unnecessary surgery and to reduce hospital stay and costs.

    ABSTRACT: Interwar Poland in the European context divorced great attention to the history of medicine and philosophy. Significant Medical History and Philosophy school took its part in Vilnius. Professor Stanislaw Trzebiński, a head of Vilnius Medical History and Philosophy school, investigated the development of Vilnius medicine in XVI-XIX centuries, constantly edited by a leading journal in the field of medical history and philosophy “The Archives for a Medical History and Philosophy as well as Nature history”. The medical history, medical logic, propedeutics, medical ethics were being taught in Stephen Bathory university Medical faculty. The aim of this paper is to make a short overview of the History of Medicine and Philosophy Department in the year 1922-1939. The activities and the most important achievements of the department will be reviewed in this review article. Correspondence to:

    ABSTRACT: The ability to phenotype wounds for the purposes of assessing severity, healing potential and treatment is an important function of evidence-based medicine. A variety of optical technologies are currently in development for noninvasive wound assessment. To varying extents, these optical technologies have the potential to supplement traditional clinical wound evaluation and research, by providing detailed information regarding skin components imperceptible to visual inspection. These assessments are achieved through quantitative optical analysis of tissue characteristics including blood flow, collagen remodeling, hemoglobin content, inflammation, temperature, vascular structure and water content. Technologies that have, to this date, been applied to wound assessment include: near infrared imaging, thermal imaging, optical coherence tomography, orthogonal polarization spectral imaging, fluorescence imaging, laser Doppler imaging, microscopy, spatial frequency domain imaging, photoacoustic detection, and spectral/hyperspectral imaging. We present a review of the technologies in use or development for these purposes with three aims: 1) providing basic explanations of imaging technology concepts, 2) reviewing the wound imaging literature, and 3) providing insight into areas for further application and exploration. Noninvasive imaging is a promising advancement in wound assessment and all technologies require further validation. This article is protected by copyright.
