Sensitizing potential of triclosan and triclosan-based skin care products in patients with chronic eczema.
The importance of treating mild atopic dermatitis.
Atopic Dermatitis (AD) is a chronic inflammatory skin disease that frequently occurs in subjects with a personal or family history of other atopic conditions, such as asthma or allergic rhinitis. The prevalence is high especially among children, and has considerably increased in recent decades. Patients and families need to understand that a single cause and treatment are unlikely to be found, but a good control is nearly always possible. It is indeed very important to treat every case of AD, without disregarding the mild forms. Treating mild forms of AD is essential to prevent disease worsening, reduce the risk of bacterial and viral complications, and possibly prevent the development of asthma and allergic rhinitis
Onset of multiple basal cell carcinoma 60 years after X-ray treatment for tinea capitis.
Basal cell carcinoma is a malignant tumour of the skin that is
often localized and rarely diffuse. It is the most common cancer
of white populations and rare in blacks. An increased incidence is seen in subjects with acquired immunodeficiency syndrome (AIDS) and in individuals receiving immunosuppressive drugs following organ transplantation.
Although exposure to ultraviolet (UV) light has long been
accepted as the main risk factor for basal cell carcinoma, the
precise relationship is unclear. Evidence that ionizing radiation
is carcinogenic for humans comes from reports of nonmelanoma
skin cancers in several radiation-exposed groups. Radiologists and subjects treated with X-rays have an increased
risk for development of skin cancer. Therapeutic radiation used for benign dermatoses, including
psoriasis, eczema and tinea capitis, may lead to onset of basal
cell carcinoma many decades later. A 72-year-old woman was referred to our dermatology
department for multiple superficial basal cell carcinomas that
had developed on her scalp over the previous 2 years. When she was 13 years old the woman had undergone X-ray
epilation of the scalp to treat tinea capitis
Fixed drug eruption from clarithromycin
A 58-year-old man was treated for tonsillitis with clarithromycin. On the 3rd day of treatment, he developed multiple sharply circumscribed erythematoviolaceous patches of various shapes and sizes (1–3 cm), some with a central blister, on the head , trunk and upper arms and legs. Lesions improved in 6-7 days just with discontinuation of the drug. 1 month later, hyperpigmentation with a red-bluish coloration was observed at the same sites.
Patch testing with clarithromycin 10% aq. was performed
on both normal skin and residual lesion. A positive
erythematovesicular reaction (D211, D411) took
place only on residual lesion, with a flare-up of the fixed
drug eruption in previously involved skin. 20 control
subjects had a negative patch test result
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
