Factores de riesgo de carcinoma espinocelular,un estudio del Centro Nacional de Dermatología de Colombia

IntroductionNonmelanoma skin cancer is the most common malignancy in white individuals. The risk factors for squamous cell carcinoma, which belongs to the family of nonmelanoma skin cancers, have not been studied in Colombia.ObjectiveTo determine the risk factors for squamous cell carcinoma in patients at a national referral center for skin diseases in Colombia.Material and methodsWe conducted a case-control study that evaluated sociodemographic, epidemiological, and clinical factors among 332 individuals. Risk was calculated as odds ratio (ORs) using the multivariate conditional logistic regression analysis method.ResultsThe following risk factors were identified: family history of skin cancer (OR, 6.55; 95% CI, 1.4-28.9), living in a rural area after the age of 30 years (OR, 3.13; 95% CI, 1.3-7.2), a lifetime working outdoors (OR, 2.98; 95% CI, 1.5-5.7), smoking more than 10 cigarettes a day (OR, 2.96; 95% CI, 1.3-6.5), actinic conjunctivitis (OR, 2.68; 95% CI, 1.2-5.9), poikiloderma of Civatte (OR, 3.29; 95% CI, 1.7-6.1), numerous facial actinic keratoses (OR, 9.23; 95% CI, 4.9-17.1), and numerous freckles (OR, 3.68; 95% CI, 1.3-10.1).ConclusionsWe have documented clinical characteristics and personal history factors that should guide the physician in making decisions on the preventive and follow-up measures to be adopted for individuals at risk of squamous cell carcinoma. These findings may help guide policy for controlling the disease using local information.     

Carcinoma de células de Merkel. Presentación de seis casos

—Merkel cell carcinoma is a biologically aggressive primary cutaneous neoplasm that is especially localized to the head and neck in persons of advanced age. It generally presents as a localized skin disease, although on certain occasions, there is evidence of regional lymphatic disease or distant metastasis at the time of the initial diagnosis. We performed a retrospective analysis of the six Merkel cell carcinoma cases diagnosed at the Hospital Clínico San Cecilio in Granada during the period from 1997-2001.

Dermatitis alérgica de contacto a dietiltiourea por un traje de pesca de neopreno

Diethylthiourea, like other thioureas, is often used by the rubber industry and in the manufacture of neoprene. We present a patient who suffered allergic contact dermatitis to diethylthiourea in a neoprene wader and who required admission to hospital and systemic treatment. We review the literature on allergy to diethylthiourea. Thioureas are not included in the standard GEIDAC (Spanish Contact Dermatitis Research Group) battery of patch tests. In these cases, it is necessary to use a special battery of rubber allergens, which includes thiourea compounds, for diagnosis of the disease and to ensure that cases of contact allergic dermatitis to thioureas do not go undiagnosed.     

Documento de consenso español para el algoritmo de tratamiento de la rosácea

Recent scientific evidence and the incorporation of new drugs into the therapeutic arsenal against rosacea have made it necessary to review and update treatment criteria and strategies. To this end, a panel of 15 dermatologists, all experts in rosacea, was formed to share experiences and discuss treatment options, response criteria, and changes to treatment. Based on a critical review of the literature and a discussion of the routine practices of Spanish dermatologists, the panel proposed and debated different options, with consideration of the experience of professionals and the preferences of patients or equality criteria. Following validation of the proposals, the final recommendations were formulated and, together with the evidence from the main international guidelines and studies, used to produce this consensus document. The goal of this consensus document is to provide dermatologists with practical recommendations for the management of rosacea.
