Self-testing for contact allergy to hair dyes – a 5-year follow-up multicentre study

Summary

Background

In 2011, a multicentre study was conducted in order to determine how hair dye manufacturers instructed consumers to perform a self-test prior to dyeing their hair, in order to identify individuals who are likely to react upon subsequent hair dyeing. A number of concerns were raised concerning the variability in instructions between products and producers, and the safety and validity of this tool.

Objectives

To perform a 5-year follow-up study in order to determine whether manufacturers still recommend a self-test, and if so, whether the procedures have been changed.

Methods

During March 2016, a total of 40 oxidative hair dye products from 21 different manufacturers were bought in retail stores in 8 European countries.

Results

The consumers were instructed to perform a self-test prior to hair dyeing for 39 of the products; however, the procedures varied greatly regarding the method of application, the amount of hair dye applied, the location and size of the application area, the number of applications, whether or not rinsing was performed after application, the reading times, and how a positive reaction was defined.

Conclusions

Self-testing is still recommended by almost all manufacturers of permanent hair dyes. There are major variations in the instructions, even in products from the same manufacturer. The previously raised concerns regarding safety and validity still remain.

BackgroundSleep disturbances in patients with dystrophic epidermolysis bullosa (DEB) have never been investigated and still remain an open question. We sought to examine sleep quality and its relationship with pain and mood disorders in DEB patients.MethodsTwenty-eight DEB patients and 26 healthy individuals completed the following battery of scales: the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), the Medical Outcomes Study (MOS) Sleep Scale, the Visual Analogue Scale (VAS), the Hamilton Rating Scale for Anxiety (HAM-A) and Depression (HAM-D). Linear correlations and hierarchical regression analyses were performed.ResultsPatients with DEB have significantly lower scores in daytime sleepiness (p = 0.003) and higher level of pain (p = 0.009) in comparison to controls. The analysis of all PSQI and MOS items failed to demonstrate any statistically significant differences between DEB patients and controls, except for a sub component of PSQI measuring sleep disturbances (p = 0.003). In the study group, a positive correlation was found between PSQI and depressive symptoms (r = 0.56; p = 0.002), anxiety symptoms (r = 0.46; p = 0.015), and pain (r = 0.44; p = 0.020). These results were consistent with the hierarchical regression analysis showing a significant contribution of depression (ΔR2 = 21.8; p = 0.008), anxiety (ΔR2 = 14.5; p = 0.027), and pain (ΔR2 = 13.5; p = 0.032) to poor quality of sleep.ConclusionsDEB patients showed a greater degree of sleep disturbances that can be influenced by depressive symptoms, anxiety symptoms, and pain compared with controls. Therefore, they should be screened for sleep issues that can be possibly impacted by pain and mood disorders.

IntroducciónEl acné juvenil es una condición muy prevalente en la población adolescente. A pesar de su alta prevalencia, es escaso el conocimiento que tienen los adolescentes de esta dermatosis. Entre las fuentes de información más utilizadas por los adolescentes destacan los amigos y los familiares. Supone una importante repercusión en la calidad de vida, con posibilidad de desarrollo de cuadros depresivos y aislamiento social.ObjetivosMejorar el conocimiento del acné de los alumnos preadolescentes y facilitarles herramientas psicológicas para una mejor relación mental con esta enfermedad.Material y métodosSe realizó un estudio experimental no controlado con adolescentes de 1.° de la ESO de 3 colegios de la Comunidad de Madrid. Se realizó un cuestionario preintervención recogiendo sus conocimientos y posicionamiento previo. Acudimos a los 3 colegios a explicarles una presentación con la fisiopatología, tratamientos y herramientas psicológicas.Posteriormente se les entregó un cuestionario postintervención pasadas 4 semanas.ResultadosN=334 estudiantes rellenaron el cuestionario preintervención y n=307 el postintervencional. Los cuestionarios no válidos no se incluyeron en el análisis estadístico (n=23 y n=16, respectivamente). La principal fuente de información son los familiares y amigos. El 50% señalan la falta de higiene como un factor clave en la aparición del acné, y un 18% considera que se contagia por contacto. Destaca la falta de conocimientos acerca de los tratamientos médicos disponibles.ConclusionesAunque se trata de una experiencia limitada, los resultados de nuestro estudio sugieren que las intervenciones psicoeducativas son una herramienta costo-eficiente, con muy buena aceptación, y útil para mejorar el posicionamiento frente a una enfermedad prevalente y con importante repercusión en la calidad de vida, como es el acné juvenil.IntroductionJuvenile acne is a very common medical condition among adolescents. Despite this high prevalence, adolescents have a remarkable lack of knowledge about this dermatosis, with friends and relatives being their most used information source. Acne has a significant impact on quality of life, and some patients may develop depressive symptoms and social isolation.ObjectiveTo improve the knowledge about acne of pre-adolescent schoolchildren, and to provide them with the psychological tools for a better approach to this condition.Materials and methodsA non-randomised experimental study was conducted on adolescents (12-14 years old) in 3 schools in the area of Madrid, Spain. A pre-interventional questionnaire was completed to determine their knowledge and attitude towards acne. Talks were given by two dermatologists in the 3 schools, and the topics covered were pathophysiology, treatments, and psychological tools. A post-interventional questionnaire was completed 4 weeks later so that the impact of the programme could be evaluated.ResultsA total of 334 students completed the pre-interventional questionnaire and 307 the post-interventional questionnaire. Questionnaires including nonsense answers were not considered for the statistical analysis (n=23 and n=16, respectively). Relatives and friends were found to be the main source of information about acne. Lack of personal hygiene was associated with acne by 50% of the participants, with 18% of the adolescents considering acne a contagious disease. It is remarkable the lack of knowledge about therapeutic options.ConclusionsAlthough this a limited experiment, the results of our study suggest that psycho-educational interventions are a well-accepted cost-effective tool that may change attitudes towards a very prevalent medical condition, and which can have a significant impact on quality of life.

Immediately after wounding, microbial colonization occurs. The effects of microbial wound colonization on healing process are particularly important and therefore, based on the significant economic and social impact of wounds, a higher level of attention and research are needed to evaluate the microbial effects on wound-healing ability and the potential new therapeutic agents that can regulate the cross-talk between microflora, pathogens and the innate immune response, and lead to wound healing acceleration. This article reviews the recent literature on the effect of human microflora, both cutaneous and gastrointestinal, on wound healing process. In addition, the latest advancements in the use of the normal microflora members that are beneficial to the host, the so-called probiotics, as a new therapeutic agent in wound management are presented and analyzed. A better understanding of the influence of microflora on wound healing, may lead to therapeutics that improve the wound management and resolve impaired wounds.
