A New Paradigm in the Management of Scalp Pruritus: Findings From the SCALP-PR Trial. / [Artículo traducido] Un nuevo paradigma en el tratamiento del prurito del cuero cabelludo: hallazgos del estudio SCALP-PR.

PURPOSE: The "Impact of scalp pruritus in dermatological consultations in Spain: The SCALP-PR trial" was initiated to address the common yet often insufficiently examined issue of scalp pruritus in dermatology. This condition leads to an uncontrollable urge to scratch, affecting the patients' quality of life and potentially causing scalp damage. This study aimed to explore the prevalence, patient profile, underlying conditions, and therapeutic approaches for scalp pruritus in Spain, and to assess the safety and efficacy profile, as well as the tolerability of a non-pharmacologic treatment. METHODS: From 2021 through 2022, 75 dermatologists enrolled a total of 359 patients in a study on scalp pruritus, approved by the Bellvitge University Hospital Research Ethics Committee, Barcelona, Spain. This evidence-based research combined a meta-analysis with observational study techniques focused on real-world evidence to examine the therapeutic impact on quality of life (QoL). Utilizing the Dermatology Life Quality Index (DLQI) for QoL assessments, the study evaluated the effectiveness of the topical product over 15 days. Data collection was conducted via an eCRF and analyzed with statistical methods to provide reliable insights into the management of scalp pruritus. RESULTS: The prevalence of scalp pruritus in Spain was found to be 6.9%, predominantly among women with a mean age of 52.5 years. The leading causes identified were seborrheic dermatitis and pruritus of undetermined etiology or sensitive scalp. Stress was noted as a key factor, with corticosteroids and hygienic measures being common therapies. The topical product demonstrated significant reductions in pruritus and scratching in more than 90% of patients after 15 days. Improvements were also seen in dermatological quality of life, with 87.1% of patients showing enhancements in DLQI scores. The product was well-received thanks to its cosmetic properties, with high ratings in texture, ease of application, and fragrance. CONCLUSION: The topical product studied is a safe, effective, and cosmetically appealing treatment, improving scalp pruritus in various etiologies for most patients. The results highlight the need for patient-center treatments in dermatology, providing important insights for clinical practice and future research.

Sensitive Scalp: Diagnosis and Practical Management. / Cuero cabelludo sensible: diagnóstico y manejo práctico.

Sensitive scalp is sensitive skin located on the scalp. Sensitivity is considered primary in the absence of an associated scalp disorder and secondary when caused by conditions such as psoriasis, seborrheic dermatitis, and atopic dermatitis. The clinical manifestations of primary sensitive scalp are subjective. Common presenting symptoms are burning, itching, trichodynia, and dysesthesia, often coinciding with hair loss. Clinically, the skin appears normal or red. An objective diagnosis based on laboratory or histologic findings is not possible. Triggers may be endogenous (e.g., stress and emotional or psychopathological disturbances) or exogeneous (e.g., topical products and cosmetics). Treatment must be individualized. Options include pimecrolimus, hydration with hyaluronic acid, and mesotherapy with plasma rich in growth factors.

Body dysmorphic disorder in patients with acne: a multicentre study.

BACKGROUND AND OBJECTIVE: Body dysmorphic disorder (BDD) is a mental disorder that is difficult to diagnose, causes a lot of suffering and is more prevalent in dermatology patients than in the general population. Our objective was to screen for possible cases of BDD in patients with acne and to determine the prevalence according to DSM-IV and DSM-5 criteria, as well as to analyse the relationship between dermatological and sociodemographic variables. METHODS: A total of 245 patients diagnosed with acne in 11 dermatological centres in Spain were included in the study by members of the Aragon Psychodermatology Research Group and Spanish Research Group of Psychiatric Dermatology. We used the Body Dysmorphic Disorder Questionnaire (BDDQ) as a screening tool. RESULTS: In our sample, we obtained a prevalence for BDD of 10.6% (95% CI: 7.6-13.6%). The prevalence was the same with DSM-IV or DSM-5 criteria. Possible cases of BDD were predominantly women (P = 0.021), and 56% had non-inflammatory lesions vs. 30% of negative patients (P = 0.002). Positive patients as possible cases of BDD spent more than two hours on average a day worrying about their appearance. Most people only worried about one part of their body (86%), and in 95% of the cases, the part of their body that worried them was the face. The three most frequent compulsive behaviours in patients who screened positive for BDD were mirror checking (90.7%), camouflaging (79.1%) and using make-up (72.1%). CONCLUSIONS: As a consequence of the high prevalence of possible cases of BDD in patients with acne observed in our study, there is a need for dermatologists to screen for BDD so that they can be referred to a mental health unit to confirm the diagnosis and be offered treatment to reduce the progression of psychosocial deterioration and the development of comorbid disorders.

Hair cosmetics: dyes.

Hair plays a significant role in body image, and its appearance can be changed relatively easily without resort to surgical procedures. Cosmetics and techniques have therefore been used to change hair appearance since time immemorial. The cosmetics industry has developed efficient products that can be used on healthy hair or act on concomitant diseases of the hair and scalp. Dyes embellish the hair by bleaching or coloring it briefly, for temporary periods of longer duration, or permanently, depending on the composition of a dye (oxidative or nonoxidative) and its degree of penetration of the hair shaft. The dermatologist's knowledge of dyes, their use, and their possible side effects (contact eczema, cancer, increased porosity, brittleness) can extend to an understanding of cosmetic resources that also treat hair and scalp conditions.

Ethics in dermatology: toward a new paradigm.

Medical ethics have evolved over time, and ethical responsibilities have often been shared by priests, the governing classes, and physicians. The emergence of scientific medicine led to the separation of functions, yet physicians have nonetheless continued to enjoy an extraordinary degree of moral authority and great social privilege. From this starting point, professional medical ethics developed as a specific moral system based on special rights and duties (paternalism and medical confidentiality). Various historical events brought this longstanding situation to a point of crisis toward the middle of the 20th century, and for several decades since, medical ethics have been based on freedom of choice for the patient with regard to decisions about his or her own body and health. Recent developments have created a new, still poorly defined model that takes into consideration such matters as euthanasia, abortion, provision of information on the benefits and harm of treatments, the sharing of therapeutic decision-making with the patient and/or family members, the choice of public or private medical providers, therapeutic guidelines, and the extension of the scope of practice to include preventive measures and cosmetic procedures. What is needed now is a new ethical system for plural societies that harbor different religions, beliefs and lifestyles, but that is also rational, universal and subject to ongoing revision-a system always striving for scientific, technical and moral excellence. Such an ethical system would have to be taught in medical schools, as it would need to bear fruit beyond mere good intentions.

[Sensitive skin: a complex syndrome]. / La piel sensible: un síndrome complejo.

Epidemiologic studies indicate that ever larger numbers of people report having sensitive skin, for which a European prevalence of 50% is estimated. Sensitive skin is characterized by hyperreactivity, with manifestations varying in relation to many factors. The pathogenesis of this disorder is poorly understood, although studies point to a biophysical mechanism. Objective diagnosis of sensitive skin is difficult, as information comes mainly from the patient's report of symptoms in the absence of effective, strongly predictive tests because of great interindividual variability in skin sensitivity. Substances that trigger a reaction in hypersensitive skin also vary greatly. The impact of this syndrome on quality of life is considerable and patients often present psychiatric symptoms; therefore, dermatologists should explore this possibility when taking a patient's history. Patient cooperation and physician persistence are both essential for treating sensitive skin.

[Feasibility and reliability of the Spanish version of the Leeds Revised Acne Grading Scale]. / Factibilidad y fiabilidad de la versión española de la escala revisada de gravedad de Leeds (LRAG) para pacientes con acné.

BACKGROUND: Although there are more than 25 acne grading systems, there is no consensus on which is most appropriate. Unification of the classifications is recommended in order to facilitate therapeutic decisions. OBJECTIVE: To assess the feasibility and reliability of the Spanish version of the Leeds revised acne grading (LRAG) scale in patients with acne vulgaris in Spain. PATIENTS AND METHODS: We conducted a prospective, multicenter, observational study in Spain, including patients with acne affecting at least 1 of 3 regions: face, back, or chest. Patients were assessed using the LRAG scale and lesion counting. Changes in the scores were determined at 4-6 weeks, and were correlated with the lesion count. Physicians were asked 4 questions regarding difficulty using the scale and the time employed. RESULTS: A total of 259 sites of acne were assessed in 239 patients at 57 centers. The majority of physicians (89.5%) stated that the LRAG scale was not difficult to use. The mean administration time was 3.12min. Cross-sectional validity (P<.012 for the face, P<.001 for the back and chest), longitudinal validity (P<.0001 for the face, back, and chest), and intraobserver and interobserver reliability (Cronbach α >0.8) were significant for inflammatory lesions in all regions. Sensitivity to change was demonstrated for lesions in all regions, based on the correlation between the difference in severity and the number of lesions recorded by the LRAG, and the difference in the lesion count between baseline and follow-up. CONCLUSION: The Spanish version of the LRAG scale is a practical and reliable tool and is sensitive to change. It is a valid tool for the objective assessment of the severity of acne.

Final Phase in the Validation of the Cross-Cultural Adaptation of the Hair-Specific Skindex-29 Questionnaire Into Spanish: Sensitivity to Change and Correlation With the 12-Item Short-Form Health Survey. / Fase final de la validación transcultural al español de la escala Hair Specific Skindex-29: sensibilidad al cambio y correlación con la escala SF-12.

BACKGROUND AND OBJECTIVE: Work has already been done on validating the cross-cultural adaptation of the Hair-Specific Skindex-29 questionnaire (HSS-29) into Spanish. This questionnaire measures the impact of female-pattern hair loss on health-related quality of life (HRQoL). The aim of this study was to complete the validation process by testing the questionnaire's sensitivity to change and assessing its correlation with the generic 12-item Short-Form Health Survey (SF-12). MATERIAL AND METHOD: Patients who started treatment with a nutritional supplement that blocks the activity of 5-alpha-reductase were seen in two visits: a baseline visit and a follow-up visit at 6months. At each visit, hair loss severity was assessed by both investigators and patients via the Sinclair scale, evaluation of hair condition, and administration of HSS-29 and SF-12. RESULTS: In total, 983 women with female-pattern hair loss participated in the study. The mean HSS-29 score decreased from 25.7±18.7 at baseline to 19.3±15.7 at follow-up and significant changes were also observed in the functioning, emotions, and symptoms domains. Changes in overall and subscale HSS-29 scores from baseline to follow-up were all significantly correlated with changes in SF-12 subscale scores. The Pearson correlation coefficients ranged from -0.1 to -0.4 and were all significant at P<.001. CONCLUSIONS: The Spanish version of HSS-29 is sensitive to change, as it detected changes in objective measurements of HRQoL. Correlations between HSS-29 and SF-12 scores were also observed.

Key Communication Skills in Cosmetic Dermatology: A 3-Pillar Model. / Dermatología Estética: habilidades humanas claves en comunicación. Modelo de los tres pilares.

Cosmetic dermatology deals with the beauty and appearance of the skin - a most important element of body image. Treatments used in cosmetic dermatology (hygiene, hydration, protection, repair) aim to enhance the characteristics of the skin, its anatomy, its function, and its vitality, to produce aesthetic improvements. Communication with the patient is essential in medical consultations and we believe that it has special connotations in cosmetic dermatology that must be taken into account. In this article, we present a 3-pillar model for communication with cosmetic dermatology patients that rests on 3 skills: assertiveness, empathy, and critical judgement.

Diagnosis and Treatment of Sensitive Skin Syndrome: An Algorithm for Clinical Practice. / Diagnóstico y tratamiento del síndrome de piel sensible: un algoritmo para la práctica clínica habitual.

Sensitive skin has traditionally been viewed as a cosmetic problem or as a purely psychosomatic alteration with a major subjective component. Different studies of its pathophysiologic etiology, however, have shown it to be a complex entity that several authors now consider to be a neurodermatological syndrome. Because of this complexity, skin sensitivity can be difficult to diagnose and treat, particularly considering that it may present with another disease. Simple tools applicable to clinical practice are thus necessary to identify and manage this disease as an independent entity. In this study, we perform a practical review of the most recent scientific advances in the area of sensitive skin that justify it being considered an individual entity, and provide tools for its identification and treatment. We propose diagnostic and treatment algorithms based on evidence from the literature and our experience and expertise.

Validation of a Cross-cultural Adaptation of the Hair Specific Skindex-29 Scale to Spanish. / Validación de una adaptación transcultural al idioma español de la escala Hair Specific Skindex-29.

BACKGROUND AND OBJECTIVE: Female androgenetic alopecia (FAA) has considerable impact on quality of life. Our analysis of the clinical scales available in the literature to measure the impact of FAA led us to choose the Hair Specific Skindex 29 (HSS29) as the most appropriate for adaptation to Spanish as a tool for following patients in treatment for FAA. This tool assesses disease impact on quality of life over time so that treatments can be tailored to patients' needs. The HSS29 score reflects impact in 3 domains (emotions, symptoms, and functioning) on a scale of 0 (no effect) to 100 (maximum effect). The scale is useful in routine clinical practice, and patients can respond to all items in 5minutes. MATERIALS AND METHODS: We followed recommended procedures to produce a cross-cultural adaptation of the scale. The process involved forward translation of the questionnaire to Spanish followed by back translation by 2 native speakers of the original language (English) and revision as needed after discussion and consensus by a committee of 3 expert dermatologists. The comprehensibility of the resulting translation was assessed in a test-retest step. Next, the psychometric properties, reliability, and construct validity were assessed. Sensitivity and specificity were evaluated with the area under the receiver operating characteristic (ROC) curve, reliability with Cronbach's α, and construct validity by factor analysis using a Varimax rotation. Face validity was also assessed during the process. The intraclass correlation coefficient (ICC) was calculated in the test-retest step. RESULTS: A total of 170 women with FAA and 30 control subjects completed the cross-culturally adapted Spanish questionnaire. A subgroup of 15 subjects responded a second time between 1 and 2 days after their first session (test-retest). Sensitivity and specificity were excellent according to the area under the ROC curve (0.98; 95% CI, 0.97-0.99), and high reliability was reflected by a Cronbach's α of 0.96. Factor analysis showed that the items were grouped in the same 3 domains (functioning, emotions, and symptoms) as in the original version of the scale. There were no significant differences in the mean (SD) scores on the test and the retest (23.05 [16.42] vs. 22.01 [17.72], respectively). The ICC of over 0.9 indicated excellent correlation between responses to the adapted Spanish version. CONCLUSIONS: The psychometric properties of the Spanish version of the HSS29 are similar to those of the original scale. The Spanish HSS29 is a useful tool for assessing quality of life in FAA.

[A cross-sectional study of the impact of educational information on topical photoprotection habits in medical students]. / Estudio transversal sobre la repercusión de la información educativa en los hábitos de fotoprotección tópica en estudiantes de medicina.

OBJECTIVES: Skin cancer (melanoma and non-melanoma) is the most common cancer in humans, with melanoma being the most aggressive. Due to the fact that ultraviolet (UV) radiation exposure is the only adjustable aetiological factor, UV protection is the essential preventive measure. Based on these grounds, a study was conducted in order to compare three population groups with different levels of knowledge about UV protection, as well as to determine any differences in sun exposure habits, and the level of awareness of the damaging effects of the sun on the skin. MATERIALS AND METHODS: An observational, cross-sectional study was conducted using a questionnaire survey of 317 Spanish university students aged 18-25years old, between October and December 2015. Descriptive statistics methods and Pearson's Chi-squared were used. RESULTS: Six questions were used to evaluate the sun exposure habits. Significant differences were detected in two of them: mole self-assessment (P<.001) and the use of an appropriate sun protection factor (P=.025). Five questions were asked concerning the level of knowledge about UV protection, with differences (P<.001) being found in all cases. CONCLUSIONS: Despite having more knowledge about the risks of sun exposure in the medical dermatology students group, only two of the six habits questioned were improved. Other factors that could be involved are the aesthetic or sociocultural factors. The early prevention of skin cancer is essential, with health promotion programs needing to be established that take into account all these conditions.

[Acromelanosis]. / Acromelanosis.

Acromelanosis is an independent disease entity, characterized by increased skin pigmentation, usually located on the acral areas of the fingers and toes. It is mostly seen in newborns or during the first years of life. Only a few cases of this entity have previously been described in the medical literature. In some of these cases, the cutaneous lesions spread to affect large parts of the skin surface. A possible association with other benign and malignant diseases has been proposed. Differential diagnosis must be made with a wide variety of systemic and dermatologic conditions, especially dermatoses with acral distribution of macular hyperpigmentation, including acropigmentation. In this article, we report a new case of acromelanosis in a 5-week-old girl showing two peculiar clinical features: associated melanosis of the genital mucosa and stabilization of the lesions after an initial phase of progression and proximal spread. In addition, the most important features of this rare cutaneous disease are discussed.
