Abstract: dowling-degos disease is a rare genodermatosis characterized principally by progressive reticulate hyperpigmentation of the flexures. although the condition is benign, it may be associated with skin malignancies. furthermore, the characteristic skin changes may be psychologically and socially detrimental to the patient as a result of the unsightliness of the condition. the present report describes a case in which this disease was associated with a keratoacanthoma, and summarizes current concepts on this skin disorder.

Anais Brasileiros de Dermatologia , 2008, DOI: 10.1590/S0365-05962008000500004
Abstract: background: rosacea is a dermatosis that has many factors associated with its onset. most studies on this condition come from the united states and european countries, with little information produced and published about the disease in the southern hemisphere, particularly in brazil. objectives: to describe the main clinical and histopathological factors associated with rosacea in population samples from southern brazil. methods: two case-control studies performed sequentially, with univariate and bivariate analysis, using p<0.05 for statistical significance (chi-square test and mantel-haenzel, for stratifications) results: rosacea is most frequent among women and in the age range of 40-50 years. almost all cases have phototypes ii and iii. the inflammatory forms of rosacea are more often diagnosed than the vascular form and there is an association with serological positivity to helicobacter pylori and with histopathological presence of demodex folliculorum (p<0.05). emotional and climatic changes, exposure to the sun and intake of alcoholic beverages were the main factors described as provoking or worsening the disease. conclusions: we have obtained an overview of rosacea in a sample of the southern population of brazil. while some data are similar to those already described internationally, other aspects, such as economic issues and the factors described as provoking or worsening the disease, are provided in greater detail.

Bonamigo, Renan Rangel;Auler, Alexandre;Duro, Kauê Marcolin;Cartell, André;
Anais Brasileiros de Dermatologia , 2007, DOI: 10.1590/S0365-05962007000600011
Abstract: infection by scedosporium apiospermum may be severe when it affects immunosuppressed patients, circumstances under which diagnosis and treatment are difficult. the authors present the case of a diabetic patient using cyclosporine, methotrexate and systemic steroids to treat rheumatoid arthritis, who presented ulcers caused by s. apiospermum. after unsuccessful treatment with itraconazole, there was good response to voriconazole therapy. this drug represents a new alternative for the treatment of fungal infections.
Staphylococcus aureus resistentes à meticilina: dissemina??o emergente na comunidade
Gelatti, Luciane Cristina;Bonamigo, Renan Rangel;Becker, Ana Paula;d?Azevedo, Pedro Alves;
Anais Brasileiros de Dermatologia , 2009, DOI: 10.1590/S0365-05962009000500009
Abstract: staphylococcus aureus is responsible for a broad variety of infectious diseases. the main concern is about methicillin-resistant isolates (mrsa), which are usually limited to hospitals. in recent years, community associated or acquired mrsa infections (ca-mrsa) have been frequently reported and emerged in the world. some phenotypic and genotypic characteristics are distinct between hospital and community infection. currently, there is reduced sensibility profile to different antimicrobials, reason why it is necessary to issue an alert to healthcare professionals, dermatologists in particular, about the importance of knowing the differences between the infections, preventing wrong and unsuccessful empirical therapy.

Anais Brasileiros de Dermatologia , 2008, DOI: 10.1590/S0365-05962008000100006
Abstract: background: allergic contact dermatitis in hiv-positive patients has not been thoroughly studied (there are only case reports). patch tests are the gold standard for diagnosis of this type of allergic reaction and have not been scientifically assessed in such patients. objective: to evaluate the applicability of patch tests in hiv-positive patients. methods: a cross-sectional, controlled and descriptive study. a group of 16 hiv-positive patients was compared to a group of 32 patients with unknown hiv sorology results. bivariate statistical analysis was performed with significance level of p<0.05. results: seven patients (43.75%) in the hiv-positive group and 18 (56.25%) in the unknown sorology group had patch positive tests. conclusions: regardless of immunodeficiency, the findings of this study suggest that specific immunologic memory and the ability to positively respond to tests may remain active. therefore, this standard and important diagnostic method for allergic contact dermatitis is valid when applied to a group of hiv patients.

Abstract: background: the abcd rule is used to guide physicians, health care professionals and patients to recognize the main characteristics of suspicious skin lesions for melanoma. in brazil there are no studies to validate the use of the abcd rule by patients after instructions given by dermatologists. objectives: to evaluate the learning of the abcd rule by patients at a dermatology center of reference in the southern region of brazil. methods: a randomized study, with 80 outpatients. the following were evaluated: sex, age, level of schooling, monthly income and access to means of communication. the intervention group received instructions regarding the use of the abcd rule and the control group did not. both groups were evaluated at three points in time (baseline; outside the office; and in the doctor's office, 15 days later) regarding their answers about a panel of photographs. the level of significance used was p < 0.05 and a power of 0.80. results: the group that received information answered correctly regarding the diagnosis of melanomas more often compared to the control group (p < 0.01).except access to radio broadcasting, which had a positive influence of the results (p < 0.05), the other variables evaluated did not influence the results. conclusions: the abcd rule can be used to train patients, above the age of 17 years, to identify changes that suggest melanoma. this learning is independent of sex, level of schooling, monthly income and access to means of communication, except the radio.

Anais Brasileiros de Dermatologia , 2006, DOI: 10.1590/S0365-05962006000200005
Abstract: abstract background: psychosocial aspects are the current focus of research on chronic dermatoses. these aspects may contribute to exacerbation of psoriasis in 40 to 80% of cases, thus having great impact on patients? quality of life. objectives: this study aims to assess coping strategies and to identify stress levels of patients with psoriasis. methods: this is a cross-sectional study of a sample of 115 patients, which included 61 patients with psoriasis and 54 patients with other chronic dermatoses as controls. instruments: the ways of coping questionnaire and the lipp stress symptoms inventory for adults. results: the coping strategies of self-control (p=0.027) and escape-avoidance (p=0.014) were the most used by patients with psoriasis and both groups present high stress levels (p=0.838). conclusion: patients with psoriasis use specific coping strategies to deal with their skin disorder when compared to other patients with chronic skin disorders; they also present stress levels as high as the control group. the integration of results enables understanding the special state of mind experienced by psoriasis patients to deal with the condition, thus showing the urgent need to develop broader intervention strategies, which also involve the social and psychic dimensions.
