Digital image management project for dermatological health care environments: a new dedicated software and review of the literature
No full textBACKGROUND/PURPOSE: Because the skin is the only organ completely accessible to visual examination, digital technology has therefore attracted the attention of dermatologists for documenting, monitoring, measuring and classifying morphological manifestations. To describe a digital image management system dedicated to dermatological health care environments and to compare it with other existing softwares for digital image storage.
METHODS: We designed a reliable hardware structure that could ensure future scaling, because storage needs tend to grow exponentially. For the software, we chose a client-web server application based on a relational database and with a 'minimalist' user interface.
RESULTS: We developed a software with a ready-made, adaptable index of skin pathologies. It facilitates classification by pathology, patient and visit, with an advanced search option allowing access to all images according to personalized criteria. The software also offers the possibility of comparing two or more digital images (follow-up). The fact that the archives of years of digital photos acquired and saved on PCs can easily be entered in the program distinguishes it from the others in the market. This option is fundamental for accessing all the photos taken in years of practice in the program without entering them one by one. The program is available to any user connected to the local Intranet and the system may directly be available in the future from the Internet.
CONCLUSIONS: All clinics and surgeries, especially those that rely on digital images, are obliged to keep up with technological advances. It is therefore hoped that our project will become a model for medical structures intending to rationalise digital and other data according to statutory requirements
Degos disease: report of a case and review of the literature
No full textWe report the case of a 20-year-old woman with one-year history of asymptomatic pink papules on the abdomen, with central atrophy. Fever and symptoms suggesting involvement of other organs were absent. Histological examination revealed wedge-shaped area of cutaneous ischemia extending into the deep dermis with superficial and deep perivascular lymphocytic infiltrate. On this basis, we diagnosed malignant atrophic papulosis. Laboratory tests and instrumental investigation did not reveal any systemic involvement. The rarity of this disease makes early diagnosis challenging, even if clinical and histological patterns of the skin lesions are peculiar
Melanoma with halo
No full textWe report this case of halo melanoma to stress that accurate clinical and dermatoscopical evaluation is essential in cases of PSL with a vitiligo-like halo, which may be misdiagnosed under the common belief that halos are associated with benign lesions
Skin diseases in geriatric patients: our experience from a public skin outpatient clinic in Siena
No full textAIM: With the progressive aging of the Italian population, geriatric health care has become a major issue for health authorities. However, little data is available regarding geriatric skin diseases. In order to provide rapid access to specialist help, in 2003 we created a dermatology clinic dedicated only to geriatric patients age 65 and older.
METHODS: To determine the characteristic pattern and the prevalence of various skin disorders among the geriatric patients seen at the clinic, we performed a retrospective and descriptive study of all skin diseases in patients seen in our office from January 2003 to December 2009. We evaluated: age, proportion and gender for all skin disease categories.
RESULTS: A total of 2100 geriatric patients were examined. The male to female ratio was 1.4 to 1. The most common disorder was pruritus "sine materia" (18.9%) followed by benign tumors (13.5%); 9.1% of our patients presented with actinic keratoses and 13.2% with malignant tumors. As reported by others, the quality of life in patients with skin cancer was better than patients with rashes as skin cancer patients tended to wait longer before seeking specialist care. To improve the assessment of skin diseases, we often worked closely with
CONCLUSION: The prevalence of skin diseases in our patients emphasized the importance of educating the elderly about sun protection, the early detection of skin cancer, the use of emollients and proper skin care in general
Like milia-like cysts
No full textWe hope with this paper we have explained the artefact of corneous pseudocysts will make the phenomenon slightly more clear to dermoscope users
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
