RESUMO
BACKGROUND: Actinic cheilitis (AC) is a chronic condition that affects mainly the lower lip. OBJECTIVES: To investigate the use of lip photoprotection in patients with AC. MATERIALS AND METHODS: A cross-sectional multicentre study of patients, ≥45 years of age, was performed in eight dermatology departments in the Galicia region over a period of one year. From 1,239 patients included in the study, 410 were diagnosed with AC and complete data were available for 408. An analysis of lip photoprotection habits and possible associations in patients with AC is reported. RESULTS: Mean age of patients with AC was 71.9 years and 53.8% were women. More than 90% of AC patients (370/408) had never used lip photoprotection. In the group of patients who used it, 62.16% of them had only used a single stick within the previous year. The only variable significantly associated with the use of lip sun protection was low Fitzpatrick's skin types I and II (p=0.039). Study limitations include the inclusion of patients 45 years or older and the use of a semiquantitative scale for measuring the frequency of application of lip photoprotection. CONCLUSION: To our knowledge, this is the first European study focused on lip photoprotection in patients suffering from AC. Only a minority of AC patients protect their lips from UV radiation. Specific lip sun protection recommendations should be promoted, especially in high-risk populations.

Actinic cheilitis is thought to be a premalignant lesion or a superficial squamous cell carcinoma. The prevalence of actinic cheilitis in Europe is unknown. The aim of this study was to determine the prevalence of actinic cheilitis in the Galicia region (north-west Spain). Secondary objectives were the description of risk factors of actinic cheilitis. A cross-sectional multicentre study in patients ≥ 45 years of age was performed in 8 dermatology departments in Galicia region during a 1-year period. The prevalence of actinic cheilitis was 31.3%. Significant and independent risk factors of actinic cheilitis after multivariate analysis were age ≥ 60 years, Fitzpatrick skin phototype II, outdoor working for more than 25 years, and previous history of non-melanoma skin cancer. This is the first cross-sectional multicentre study of the prevalence of actinic cheilitis in Europe. Actinic cheilitis was present in almost one-third of the screened patients. Lip examination should be performed in all patients with chronic actinic damage.

La sarcoidosis es una enfermedad multisistémica de etiología desconocida que afecta sobre todo a adultos jóvenes y que se caracteriza por la formación de granulomas epitelioides no caseificantes en diversos órganos. Afecta principalmente a pulmones, ganglios linfáticos, ojos y piel. Las manifestaciones de la sarcoidosis cutánea son de dos tipos: unas son específicas, con formación de granulomas no caseificantes; las otras son inespecíficas, como el eritema nudoso. La infiltración de cicatrices antiguas es una manifestación específica de sarcoidosis. Aportamos el caso de una mujer joven que refería cambios en sus cicatrices, secundarias a una explosión de gas. El estudio histológico mostró granulomas sarcoideos que afectaban a casi toda la dermis. Se objetivaron alteraciones en las pruebas de función hepática. Cinco meses después sufrió una uveítis. Se comentan los aspectos etiopatogénicos, diagnóstico diferencial, tratamiento y pronóstico de la sarcoidosis de las cicatrices. Ésta puede ser la primera y única manifestación de una sarcoidosis sistémica (AU)

La vasculitis reumatoide es una complicación rara de la artritis reumatoide con una alta tasa de mortalidad debido a vasculitis sistémica y a infecciones. Presentamos el caso de una mujer de 70 años con una artritis reumatoide grave que presentó un brote intenso de vasculitis reumatoide, afectando a la piel, así como neutropenia y fiebre. En este caso la neutropenia autoinmune incrementa la susceptibilidad a infecciones bacterianas y es una factor limitante para el tratamiento con agentes citostáticos. Creemos que es una paciente interesante debido a la combinación de vasculitis, neutropenia y fiebre que represena una situación crítica en dermatología, y estas situaciones son poco frecuentes en nuestra práctica diaria (AU)
