Translation, cross-cultural adaptation and validation of the "Cardiff wound impact schedule," a wound-specific quality of life instrument, to the native Spanish of Mexican patients.

The aim of this study was to translate into Mexican Spanish, cross-culturally adapt and validate the wound-specific quality of life (QoL) instrument Cardiff wound impact schedule (CWIS) for Mexican patients. This instrument went through the full linguistic translation process based on the guidelines of Beaton et al (Beaton DE, Bombardier C, Guillemin F, Ferraz MB, Guidelines for the process of cross-cultural adaptation of self-report measures, Spine Phila Pa, 1976, 2000, 318-391). We included a total of 500 patients with chronic leg ulcers. The expert committee evaluated the Face validity and they agreed unanimously that the instrument was adequate to assess the QoL of these patients, covering all relevant areas presented by them. The content validity index obtained was of 0.95. The construct validity demonstrated moderately significant correlations between related sub-scales of CWIS and SF-36 (P = .010 to P < .001). The instrument was able to discriminate between healed and unhealed ulcers. The instrument obtained an overall Cronbach's alpha of .952, corresponding to an excellent internal consistency (.903-.771 alpha range for domains). The CWIS can be appropriately used to assess the health-related QoL of Mexican patients with chronic leg ulcers.

A case series and a review of the literature on foreign modelling agent reaction: an emerging problem.

Foreign modelling agent reactions (FMAR) are the result of the injection of unapproved high-viscosity fluids with the purpose of cosmetic body modelling. Its consequences lead to ulceration, disfigurement and even death, and it has reached epidemic proportions in several regions of the world. We describe a series of patients treated for FMARs in a specialised wound care centre and a thorough review of the literature. A retrospective chart review was performed from January 1999 to September 2015 of patients who had been injected with non-medical foreign agents and who developed cutaneous ulceration needing treatment at the dermatology wound care centre. This study involved 23 patients whose ages ranged from 22 to 67 years with higher proportion of women and homosexual men. The most commonly injected sites were the buttocks (38·5%), legs (18%), thighs (15·4%) and breasts (11·8%). Mineral oil (39%) and other unknown substances (30·4%) were the most commonly injected. The latency period ranged from 1 week to 17 years. Complications included several skin changes such as sclerosis and ulceration as well as systemic complications. FMAR is a severe syndrome that may lead to deadly complications, and is still very common in Latin America.
