The invention relates to a non-dusting homogeneous pigment preparation which is notable in that it comprises at least 40% by weight of one or more effect pigments, from 0.5 to 60% by weight of an aldehyde resin and/or ketonic resin and from 0.1 to 10% by weight of a redispersant.

A statistical procedure to evaluate melanoma risk in Caucasian subjects on the basis of colorimetric measurement of skin colour and Fitzpatrick phototype is described. One hundred and sixty melanoma patients and 546 randomized healthy subjects of similar age, sex and place of origin were examined in the same period for skin colour using a tristimulus colorimeter and for Fitzpatrick phototype. A clinical score for classification purposes was obtained by statistical discriminant analysis with mult...

Abstract Background: To enhance the clinical evaluation of pigmented skin lesions (PSL), examination of PSL at a high magnification and computer-aided diagnosis have been introduced. Besides surface microscopes, "videomicroscopes" that are provided with polarized light are commercially available. Images recorded in the polarizing mode are comparable with those obtained after application of a drop of oil and a glass slide. Objective: The purpose of this study was to evaluate the usefulness of a d...

Lifetime risk for malignant melanoma has increased from 1 in 1500 in the United States in 1930 to 1 in 75 projected for the year 2000. Because the tumor’s thickness at excision is the primary prognostic determinant, early detection through the history and physical examination can play an important role in the patient’s clinical course. Two checklists have been developed as diagnostic aids, the ABCD (A indicates asymmetry; B, border irregularity; C, irregular color; and D, diameter .6 mm) and the...

A novel criterion is introduced for eliminating false contours detected as zero-crossings in images processed by means of a Laplacian-of-Gaussian filter. Each candidate contour point is given a score and is retained only if such a value exceeds a threshold which is related to image contrast and independent of the noise. After all the zero-crossings of a contour have been classified, the whole contour is either accepted or rejected depending on its percentage of validated contour points. The thre...

Melanoma has a very bad reputation, and rightfully so. Until relatively recently, the prognosis for melanoma was dismal and, very reasonably, early detection has been proposed as a viable approach to preventing melanoma deaths. On the surface, this simple approach appears to have been a stellar success, with melanoma survival rates improving markedly. There is no question that there has been a dramatic increase in the number of people with a diagnosis of melanoma. On careful scrutiny, the number...

Abstract In vivo cutaneous surface microscopy, epiluminescence microscopy, dermoscopy, dermatoscopy and magnified oil immersion diascopy, are terms that describe the use of an incident light magnification system to examine cutaneous lesions, usually with immersion oil at the skin-microscope interface. The result is the visualization of a multitude of morphological features, not visible with the naked eye, that enhance the clinical diagnosis of nearly all pigmented lesions. Sixty-two invasive mel...

Background/aims: It has now been established that ELM significantly improves the clinical diagnosis of pigmented skin lesions, particularly when associated with image analysis on digital pictures. Besides surface microscopes, so called “videomicroscopes” are nowadays commercially available. Thanks to their practicality and to their reasonable price and small volume, they could be usefully employed by general practitioners or peripheral dermatologists in their practice. The aim of our study was t...

Abstract Background: Although a major problem with the classification of epiluminescence microscopy (ELM) findings is the lack of standard definitions, reproducibility of the criteria proposed has never been investigated. Objectives: Our purposes were (1) to perform a review of four major published classifications to obtain a set of apparently well-defined ELM variables and descriptors and (2) to evaluate the ability of one of us to report consistently ELM findings in melanocytic lesions accordi...

Abstract Background: Most epidemiologic studies on risk factors for cutaneous melanoma have been performed in predominantly fair-skinned populations. Objective: Our purpose was to assess by means of a case-control study the importance of common melanocytic nevi (CMN) and clinically atypical nevi (CAN) as risk factors for cutaneous melanoma in a Mediterranean population. Methods: One hundred six patients with invasive cutaneous melanoma and 109 population control subjects were included in the stu...

Asymmetry, color variegation and diameter are considered strong indicators of malignant melanoma. The subjectivity inherent in the first two features and the fact that 10% of melanomas tend to be missed in the early diagnosis due to having a diameter less than 6mm, deem it necessary to develop an objective computer vision system to evaluate these criteria and aid in the early detection of melanoma which could eventually lead to a higher 5-year survival rate. This paper proposes an approach for e...

The ABCD rule is a simple framework that physicians, novice dermatologists and non-physicians can use to learn about the features of melanoma in its early curable stage, enhancing thereby the early detection of melanoma. Since the interpretation of the ABCD rule traits is subjective, different solutions have been proposed in literature to tackle such subjectivity and provide objective evaluations to the different traits. This paper reviews the main contributions in literature towards automating ...

In medical practice early accurate detection of all types of skin tumours is essential to guide appropriate management and improve patients’ survival. The most important is to differentiate between malignant skin tumours and benign lesions. The aim of this research is classification of skin tumours by analyzing medical skin tumour dermoscopy images. This paper is focused on a new strategy based on hybrid model which combines mathematics and artificial techniques to define strategy to automatic c...
