Repair of Nasal Tip Defects Using the Crescentic Nasojugal Flap: A Series of 13 Cases. / Colgajo crescéntico nasoyugal en la reconstrucción de defectos de punta nasal: una serie de 13 casos.

Reconstruction of the tip of the nose following the excision of skin cancer is a cosmetic and surgical challenge. We propose using a crescentic nasojugal flap, also known as a perialar crescentic advancement flap, to repair such defects. We present a series of 13 cases in which cutaneous carcinoma (mostly basal cell carcinoma) was excised from the lateral nasal tip with clear margins and the defect repaired with a crescentic nasojugal flap. The technique was successful in all cases. None of the patients developed notable surgical complications and the postoperative outcomes were satisfactory, with no significant functional or cosmetic problems. The crescentic nasojugal flap is therefore a good option for repairing medium-sized defects on the tip of the nose.

[Secondary effects of topical application of an essential oil. Allergic contact dermatitis due to tea tree oil]. / Efectos secundarios de la aplicación tópica de un aceite de esencial. Dermatitis alérgica de contacto a aceite de árbol de té.

BACKGROUND: Tea tree oil is an essential oil, whose use is increasing in our setting, due both to its supposed medicinal effects and to its aromatic properties. We describe our experience with allergic contact dermatitis following the application of this oil. MATERIAL AND METHODS: Five patients in the last 5 years (0.4% of all the patients studied in specialized consultation) reacted to a 5% concentration of tea tree oil in Vaseline. RESULTS: All the patients presented strong reactions, and in all cases these were considered relevant. Three of them also reacted to oxidized d-limonene, one of the components of tea tree oil, which is present in our standard series. CONCLUSIONS: Different cases have been described in the literature on allergic contact dermatitis due to tea tree oil, but until recently it was infrequent in our setting. With the increased popularity of alternative and natural therapies we have witnessed several cases of sensitization to this essential oil, which had been used to treat several supposedly "infectious" skin diseases, but which were very probably different forms of dermatitis.

[Lip eczema. Experience in the Contact Dermatitis Unit of a Spanish tertiary hospital]. / Eccema de labios. Experiencia en la Unidad de Eccema de Contacto de un centro terciario español.

BACKGROUND: Lip eczema is an infrequent problem in Contact Dermatitis Units (CDU). Very few series have been published to date that show the profiles of such patients and the causes of their eczemas, and none are Spanish. The goal of this study was to analyze the epidemiological profile of the patients who attend a CDU in our setting, the main diagnoses and the relevant allergens. METHODS: A retrospective review was made of the patients referred to the CDU in the 2005-2014 period. Patch tests were carried out with the extended standard series of the Spanish Research Group on Allergic Contact Dermatitis (Grupo Español de Investigación en Dermatitis Alérgica de contacto - GEIDAC), our own products and other complementary sets. RESULTS: The most frequent diagnoses in the 78 patients studied were allergic contact dermatitis and atopic dermatitis. The most frequent relevant allergens were cosmetics and topical medications. CONCLUSIONS: It is essential to study the patients with lip eczema with patch tests to be able to correctly determine their etiology and accordingly to carry out the most suitable treatment.
