Quality of life in dermatology

Impact of Chemotherapy-Induced Nail Changes on Quality of Life: A Cross-Sectional Study from a Tertiary Care Centre

Background

Chemotherapy has increased survival rate in patients but is associated with systemic as well as cutaneous adverse effects. Among cutaneous adverse effects, nail changes caused by chemotherapy are often overlooked. But these changes are a major cause of cosmetic concern and negatively affect the quality of life (QoL) of patients.

Aim

This study was conducted to evaluate the impact of chemotherapy-induced nail changes on QoL of patients with malignancy and to compare the severity of impact on QoL in various nail changes.

Materials and Methods

This hospital-based cross-sectional observational study was conducted for a period of 12 months. Only patients on chemotherapy who developed nail changes were included in the study. A nail-specific QoL questionnaire was used. Statistical analysis was conducted to evaluate the impact of nail changes on QoL.

Results

The mean QoL score of 188 patients was 32.37 ± 7.9. The mean QoL score of females was more than that of males. QoL was statistically more significant in younger age groups [<20 years: 46.71 ± 1.7] (P < 0.001). Patients with pigmentary nail changes (melanonychia and leukonychia) had more significant impact on QoL (P < 0.001).

Conclusion

There is a significant impact of chemotherapy-induced nail changes on QoL of patients leading to psychological distress, reduced self-confidence and social limitation. This highlights the importance of proper counselling of patients beforehand regarding the possibility of associated nail changes during and after the chemotherapy regimens.

Quality of life in Hidradenitis Suppurativa (Acne Inversa): A scoping review

Background

Hidradenitis Suppurativa (HS) is a chronic, relapsing, inflammatory skin condition which is physically, psychologically and socially disabling and often affects a patient's quality of life (QOL). There are numerous QOL tools used in dermatology. However, assessment of QOL in patients with HS is difficult due to the inability of generic QOL tools to specifically capture QOL in patients with HS. Numerous HS-specific QOL tools have been developed in recent years. It is important to identify evidence on full psychometric evaluation of these tools.

Objectives

There has been a gradual increase in the use of generic and disease-specific QOL tools in the last few decades. The aim of this scoping review (SR) is to evaluate the most widely used generic QOL tools and HS-specific QOL tools to identify the psychometric evaluation of such tools.

Methods

Design: An SR guided by Joanna Briggs Institute manual and Arskey O'Malley framework guidelines. Data extraction included the studies available on full psychometric evaluation of the most widely used dermatology generic QOL tools in HS and HS-specific QOL tools.

Results

Ten papers were included in the review, eight papers demonstrated HS-specific QOL assessment tools. The psychometric properties of these tools were underpinned by reliability, validity and sensitivity measurement. Six disease-specific tools were identified in this SR. However, they all lack full psychometric evaluation.

Conclusion

This review indicates that an extensive research in the field of QOL tools for HS is much needed. It is crucial to develop user-friendly and validate disease-specific tools to measure the real impact of disease on patients QOL. QOL instruments can evaluate the impact on life of an HS patient, thus helping improve intervention and management of disease. There is a necessity for more research into existing HS-specific QOL tools and they should be widely tested and fully validated.

Subcision, chemical peels, and platelet-rich plasma: Combination approaches for the treatment of striae distensae

Striae distensae (SD) are disfiguring skin condition causing cosmetic troubles and psychological distress. The aim was to compare the efficacy and safety of platelet-rich plasma (PRP) versus its combination with subcision or medium-depth peeling (glycolic acid 70% followed by trichloroacetic acid [TCA] 35%) for SD treatment. Seventy-five female patients with SD were divided into three equal groups with the contralateral side in each patients represented the control group. Group A treated with PRP, group B received PRP + subcision while group C received PRP + combined peeling (GA 70% + TCA 35%). Primary outcome included clinical improvement, patients' satisfaction, and Dermatology Life Quality Index (DLQI). Striae measurement, skin biopsies were also assessed. Very much improvement was achieved in 28%, 44%, and 36% in groups A, B, and C respectively. The combined groups (B and C) showed significantly higher patients' satisfaction and DLQI than group A (p = 0.03), (p < 0.0001). A significant decrease in all striae measurements was achieved with all groups (p < 0.001); however, groups B and C showed more decrease (p = 0.2 and 0.4). A highly significant decrease in the mean number of sessions was found in group B (p < 0.0001). All groups demonstrated improvement in dermal collagen deposition, which was higher in the combined groups. Side effects were mild and well tolerated. The combination of PRP with subcision or peeling was more effective and offered a higher therapeutic response than PRP alone. Moreover, the subcision has superior efficacy in striae albae and safer in darker skin types.

The Influence of Atopic Dermatitis on Health-Related Quality of Life in Bangladesh

Atopic dermatitis (AD) is the foremost non-fatal skin-related disease that affects all age groups. Despite the growing prevalence of AD in low- and middle-income countries, its physiological consequences remain overlooked in countries like Bangladesh. Therefore, we aim to assess and characterize the influence of AD on the health-related quality of life (HRQoL) in Bangladeshi patients. A cross-sectional study comprising 184 eligible adults (83 men and 101 women; mean age, 33.46 ± 15.44 years) was conducted at the dermatology outpatient department of Shaheed Suhrawardy Medical College Hospital (a tertiary hospital in Dhaka, Bangladesh). AD was determined using the UK Working Party criteria. A structured questionnaire, Eczema Area and Severity Index (EASI), and Dermatology Life Quality Index (DLQI) were administered to obtain information on patient characteristics, AD severity, and HRQoL. The mean DLQI score for the entire sample was 11.29 ± 5.27 (range, 1–26), and 51.60% reported the disease greatly affected their lives. Bivariate analysis revealed significant differences in self-rated health measures of DLQI scores in terms of self-reported AD severity, overall health, and the EASI. In multivariable regression models adjusted for patient characteristics, the self-perceived severe AD group reported significantly higher DLQI scores (coefficient = 2.72; 95% confidence interval (CI) = 0.38–5.05; p = 0.022) than the mild group. Concurrently, we observed a substantial increase in the DLQI scores among patients with moderate and severe EASI scores (coefficient = 1.96, 95% CI = 0.08–3.92, p < 0.05 and coefficient = 4.35, 95% CI = 1.98–6.72, p < 0.001, respectively) than in those with mild EASI scores, suggesting that HRQoL was markedly influenced by greater AD severity. These findings highlight the need for a more patient-centric approach to the management of AD in order to alleviate patient suffering and, thereby, improve HRQoL.

Validation of the Skindex-17 quality of life assessment instrument for a Brazilian population

BACKGROUND

Health-related quality of life assesses how diseases affect the daily life of people; there are several generic instruments for this assessment in dermatology. Skindex was created in 1996; it is a multidimensional instrument, aiming to encompass some psychological and social aspects not yet addressed by other questionnaires. Among its versions (Skindex-29, 16, and 17), Skindex-17 had not been validated in Brazil.

OBJECTIVES

To validate Skindex-17 for use in Brazilians with dermatological diseases.

METHODS

This was a methodological, cross-sectional, and prospective study of 217 patients attended at the Dermatology Service Outpatient Clinic, Faculdade de Medicina de Botucatu - Universidade Estadual Paulista (Botucatu, SP, Brazil), from December 2017 to September 2019. The following were evaluated: content validity, filling time, internal consistency, dimensional structure, concurrent validity (DLQI), temporal stability, and responsiveness.

RESULTS

The sample consisted of 71% women, mean age (SD) of 45 (16) years; phototypes II-IV accounted for 95% of the cases. Cronbach's alpha coefficients were 0.82 and 0.93 for the symptoms and psychosocial conditions, respectively. A high correlation was observed with the DLQI score: symptoms (rho = 0.69) and psychosocial conditions (rho = 0.75). The instrument's two-dimensional structure was confirmed through confirmatory factor analysis. Temporal stability (ICC > 0.9) and score responsiveness (p ≤ 0.02) were verified. The instrument was shown to be feasible in clinical practice due to the content validation performed by professionals and patients, as well as the low time spent completing it (< 5 min).

STUDY LIMITATIONS

Single-center study, with patients exclusively from the public healthcare system.

CONCLUSIONS

Skindex-17 was shown to be a valid and consistent instrument for assessing quality of life among patients with dermatological diseases, in Brazil. Its two-dimensional structure was confirmed.

A Study of Quality of Life in Patients with Facial Melanoses

Context:

Facial melanoses decreases the quality of life (QoL). Melasma is the commonest cause but there are various other etiologies for facial pigmentation.

Aims:

To study the clinical profile of patients with facial melanoses and the psychological burden in these patients.

Settings and Design:

All patients having patchy or diffuse facial pigmentation attending the OPD in a tertiary care hospital for a period of 1 year were included in this hospital based cross-sectional study.

Subjects and Methods:

The type, extent, and distribution of the pigmentation was noted and tabulated in all patients. All patients were explained about Skindex-16 questionnaire and asked to complete it.

Statistical Analysis Used:

Student t-test (two tailed, independent) was used to find the significance of study parameters on continuous scale between two groups. Chi-square/Fisher Exact test was used to find the significance of study parameters on categorical scale between two or more groups. Correlation was performed using Spearman corrélation.

Results:

The total number of cases studied was 238 of which 186 (78.2%) were females and 52 (21.8%) were males. The most common diagnosis was melasma seen in 73% of cases. Other conditions noted were phototanning (5.8%), post-inflammatory hyperpigmentation (5.8%), Lichen planus pigmentosus (4.2%), freckles (3.7%), and Nevus of Ota (1.6%). Skindex-16 score against different grades of pigmentation showed that the mean Skindex-16 score was higher in severe cases but there was no statistically significant difference between the groups.

Conclusions:

The extent and severity of facial pigmentation and the decrease in the QoL are not proportional.

Health-related quality of life in porphyria cutanea tarda: a cross-sectional registry based study

BACKGROUND

Porphyria cutanea tarda (PCT) is a rare, photosensitive disease characterized by skin fragility and blistering on sun-exposed areas. There is little previous research on how this condition affects health-related quality of life (HRQoL) and to the best of our knowledge this is the largest sample of PCT patients surveyed about their HRQoL. The aims of this study were to describe HRQoL, symptoms, susceptibility factors, disease activity and treatment in patients with PCT, and investigate the associations between these factors.

METHODS

This is a cross-sectional, retrospective study based on patient-reported outcome and laboratory data. The Norwegian Porphyria Centre diagnoses all patients with PCT in Norway, all of whom are invited to participate in the Norwegian Porphyria Registry. Between December 2013-2015, 111 patients received a postal questionnaire and invitation to participate.

RESULTS

Sixty-eight persons responded, with seven being excluded due to prolonged response time or missing information, resulting in 61 participants in the final analyses (55%). Median age was 60 years and 33 were female. We found a moderate negative relationship between the type and localisation of PCT symptoms and both mental (r = -.354 p < 0.01) and physical (r = -.441, p < 0.01) aspects of HRQoL. Participants who had started treatment when answering the questionnaire reported significantly better physical functioning and less bodily pain than those who had not started treatment. We did not observe an association between biochemical markers of disease activity and symptoms or HRQoL. Itching, a symptom that has received little attention in PCT was reported by 59% of the participants.

CONCLUSIONS

Our results show that reduced HRQoL is associated with more symptoms and not having started treatment. PCT is a rare disease, and there is a need for the development of best-practice guidelines to facilitate good patient care.

A Quality of Life Study of Patients with Leprosy Attending the Dermatology OPD of a Tertiary Care Center of Eastern India

BACKGROUND

Leprosy is a chronic infectious disease caused by Mycobacterium leprae affecting the skin, peripheral nervous system, and other tissues. The disease is associated with social stigma, and the patients sometimes suffer social discrimination because it often leads to visible physical deformities. Hence, leprosy may have severe impact on the quality of life (QoL) of patients.

AIMS AND OBJECTIVES

The aim of this study was to assess the effect of leprosy on the QoL of the affected patients and to find out whether there is some association with certain demographic and clinical factors.

MATERIALS AND METHODS

The Dermatology Life Quality Index (DLQI) questionnaire was used to assess the QoL of 114 patients with leprosy who attended dermatology outpatient department of a tertiary care center of eastern India. This was a cross-sectional study.

RESULTS

Among a total of 114 patients, leprosy had no impact on the QoL of 15 (13.16%) patients. There was a mild impact in 23 (20.18%) of the patients. There was moderate impact in 37 (32.46%) of the patients. The disease had severe impact in the QoL of 39 (34.21%) patients. None of the patients had a very severe impact. Several of the clinical aspects such as nerve involvement, systemic features, deformity, disability grade, and type of leprosy have significant impact on QoL. Among the demographic factors, gender had some effects on QoL.

CONCLUSION

Leprosy adversely affects the QoL of those affected. Although it is considered a social disease, at least in our part of the country, demographics have minimal effect on the QoL. Rather, important clinical aspects such as systemic features, nerve involvement, reaction, deformity, and disability have profound impact on the QoL of the patients.

Quality of Life and Disease Impact of Atopic Dermatitis and Psoriasis on Children and Their Families

Atopic dermatitis (AD) and psoriasis are common chronic skin diseases affecting children. These disorders negatively impact the quality of life (QoL) of patients in health-related aspects such as physical, psychosocial, and mental functioning. This health impact is more accurately represented when accounting for the numerous comorbidities associated with each disorder, and the impact the disorders have on patients’ families. A number of QoL tools have been developed and can be routinely implemented in the evaluation of QoL in pediatric patients and their caregivers. Ways to improve QoL include a multidisciplinary approach to care, education, and psychological support.

Correlation between chronic skin ulcers dimension and burden of suffering evaluated with PRISM test

BACKGROUND

In the practice of dermatology, many tools are available to help the physician measure the patient's quality of life. The Pictorial Representation of Illness and Self Measure (PRISM) is a novel and simple method to measure personal suffering. The aim of our study was to evaluate, using PRISM, whether the reduction of the ulcers' size positively correlated with an improvement of the patients' suffering.

METHODS

This was a multicenter national prospective study. 143 patients from five dermatological centers were enrolled in the study. At times T0 and T1 (after 1 month), the size of the ulcers was collected for each patient. At the same time, the PRISM test was also administered, in order to calculate the Self-Illness-Separation (SIS).

RESULTS

First, a substantial decrement of the size of the ulcer seemed to correlate with a significant difference between the SIS score obtained at T0 and T1. On the contrary, the duration of the wound did not seem to influence the SIS value. No relationship between the age of the patient and the SIS value was found either.

CONCLUSIONS

Our study showed that the decrease in the wound dimension positively affects the patient's suffering. In fact, ulcer's size reduction is correlated with an improvement in the patient's disease perception.

Is There a Correlation between Severity of Melasma and Quality of Life?

BACKGROUND:

Melasma is a common chronic acquired hyper melanosis. It has significant impacts on appearance, psychosocial and emotional distress, hence reducing the quality of life of the affected patients. Melasma quality of life scale (MelasQoL) is a new quality of life (QoL) questionnaire consists of 10 questions, scored from 1 to 7, with higher index scores indicating poor QoL. The severity of melasma can be assessed by the Melasma Area and Severity Index (MASI) score.

AIM:

We aimed to determine the correlation between the severity of melasma (MASI score) and quality of life.

MATERIAL AND METHODS:

This was a cross-sectional analytic study involving 30 subjects with melasma. The diagnosis was made based on history, clinical features and by Wood’s lamp examination. MASI score was determined to assess the severity of melasma. Subjects answered 10 items of MelasQol questionnaire. All collected data were processed and statistically analysed by Spearman correlation test to determine the association of MASI score with MelasQoL. Association of quality of life with clinical pattern and depth of lesion were analysed by Mann Whitney test.

RESULTS:

There was no significant correlation between MASI score and MelasQoL (p = 0.797; r = 0.049). Likewise, there was no association of quality of life with clinical pattern type (p = 0.12) and depth of lesion (p = 0.92).

CONCLUSION:

There was no significant correlation between the MASI score and quality of life.

Development and validation of a multidimensional questionnaire for evaluating quality of life in melasma (HRQ-melasma)

BACKGROUND

Melasma has a major impact on quality of life. MELASQoL is the only validated specific psychometric instrument to evaluate melasma QoL.

OBJECTIVE

To develop and validate a multidimensional questionnaire for evaluating quality of life related to facial melasma.

METHODS

Cross-sectional study performed in 2 institutions (public and private) from Brazil. Two focus groups were carried out: 5 board-certified dermatologists and 10 melasma patients, indicating the dimensions and significant units of melasma QoL. The preliminary questionnaire with 49 itens was applied to 154 facial melasma patients. Item reduction was performed by Rasch analysis. Parallel evaluations of clinical (MASI), demographic, and QoL aspects (MELASQoL, DLQI) were performed. The dimensional structure was assessed by confirmatory factor analysis. Temporal stability was tested in a subgroup of 42 individuals within 7-14 days.

RESULTS

The mean (SD) age of the 154 interviewed subjects was 39±8 years, and 87% were females. The median (p25-p75) DLQI and MELASQoL were: 2 (1-6) and 30 (17-44). HRQ-Melasma consisted of 19 items distributed in 4 dimensions: Physical/Appearance, Social/Professional, Psychological, and Treatment. Cronbach's alpha for HRQ-Melasma was 0.96, and >0.74 for each dimension. There was high correlation between HRQ-Melasma and DLQI and MELASQoL (rho=0.80 and 0.83), but modest with MASI (rho=0.35). Dimensional structure of HRQ-Melasma was stated by confirmatory factor analysis coefficients. Test-retest analysis disclosed an intraclass correlation coefficient of 0.91 (p<0.01).

STUDY LIMITATIONS

Single-center study.

CONCLUSIONS

A specific instrument to evaluate QoL in melasma with multidimensional characteristics was developed and validated, with appropriate psychometric performance.

The Brazilian version of Skindex-16 is a valid and reliable instrument to assess the health-related quality of life of patients with skin diseases

INTRODUCTION

The aim of this study was to assess the psychometric properties of the Brazilian version of Skindex-16 in patients with various skin diseases.

METHODS

Dermatologic assessments were performed for the diagnosis and classification of the severity of skin conditions. The clinical feasibility of Skindex-16 was assessed based on the time required to complete the questionnaire and the number of unanswered items. The participants (n = 110) answered the Hospital Anxiety and Depression Scale (HADS), the Dermatology Life Quality Index (DLQI) and the Skindex-16 (Portuguese/Brazil version) questionnaires. Convergent validity was assessed based on the correlation of the Skindex-16 with the DLQI and HADS subscales. Known-groups validity was assessed based on the comparison of the mild, moderate and severe disease groups using the Kruskal-Wallis test. Internal consistency was assessed using Cronbach's alpha and test-retest reproducibility using the intraclass correlation coefficient (ICC) obtained with 29 participants who answered the Skindex-16 a second time 3 to 10 days after the first assessment.

RESULTS

The mean time to answer the questionnaire was 2 min 41 sec. Cronbach's alpha scores were 0.867, 0.930 and 0.888 for the Skindex-16 domains symptoms, emotions and functioning, respectively. The ICCs were 0.947, 0.860 and 0.843 for the Skindex-16 domains symptoms, emotions and functioning, respectively. All three Skindex-16 scales exhibited strong correlations with DLQI. Moderate correlations were found between HADS subscales and the Skindex-16 emotions domain. Known-groups validity showed differences in all three Skindex-16 domains between the mild and moderate skin disease groups (emotions: p < 0.001; symptoms: p = 0.049; functioning: p < 0.001) and between the mild and severe skin disease groups (emotions: p = 0.002; symptoms: p = 0.001; functioning: p = 0.002).

CONCLUSION

The Portuguese/Brazil version of Skindex-16 is a valid and reliable instrument to assess the quality of life of patients with skin diseases.

The prevalence of psychological comorbidity in people with vitiligo: a systematic review and meta-analysis

BACKGROUND

Vitiligo is a chronic disorder causing skin depigmentation with global prevalence varying from 0·2% to 1·8%. U.K. guidelines recommend assessment of psychological state during clinical evaluation of vitiligo. However, the prevalence of psychological comorbidity in people with vitiligo has not been described.

OBJECTIVES

To establish the prevalence of psychological symptoms or disorders in people with vitiligo and describe the outcome measures used.

METHODS

We performed a comprehensive search of MEDLINE, Embase, CINAHL and PsycINFO to identify observational studies assessing the prevalence of psychological symptoms or disorders (December 2016). DerSimonian and Lard random-effects models were used to estimate the overall pooled prevalence.

RESULTS

We identified 29 studies with 2530 people with vitiligo. Most studies included a measure of either depression (n = 25) or anxiety (n = 13). The commonest tools were the Hospital Anxiety and Depression Scale and the Centre for Epidemiology Studies Depression Scale. Ten studies provided information on 13 other psychological outcomes. Pooled prevalence using depression-specific and anxiety-specific questionnaires was 0·29 [95% confidence interval (CI) 0·21-0·38] and 0·33 (95% CI 0·18-0·49), respectively. Prevalence was lower for clinically diagnosed depression (0·21, 95% CI 0·15-0·28) and anxiety (0·15, 95% CI 0·06-0·24). When nonspecific tools were used the prevalence remained similar for depression (0·27, 95% CI 0·08-0·46) but increased for anxiety (0·46, 95% CI 0·39-0·52). High heterogeneity was observed.

CONCLUSIONS

A range of psychological outcomes are common in people with vitiligo. The prevalence of anxiety was influenced by type of screening tool, suggesting the need for validation of psychological outcome screening tools in the field of dermatology.

The Use of PRISM (Pictorial Representation of Illness and Self Measure) in Patients Affected by Chronic Cutaneous Ulcers

OBJECTIVE

PRISM (Pictorial Representation of Illness and Self Measure) is a nonverbal visualization instrument. The authors chose to use this tool to avoid the limitation of the other tests for the assessment of quality of life by using interview methods that depend on the cognitive and cultural level of the patient. The aim of the study was to assess the impact on the quality of life of different types of chronic wounds using the PRISM test.

SETTING

The PRISM test was administered by the same medical student to each patient visiting the dermatology department for a routine visit and medication.

PARTICIPANTS

The PRISM test was administered to 77 patients with chronic cutaneous ulcers referred to the Dermatology Department of the Spedali Civili of Brescia, Italy.

MATERIALS AND METHODS

The authors analyzed the "Self-llness-Separation"' (SIS) value, which resulted from the PRISM test, and related it to sex, age, and ulcer etiology.

RESULTS

Considering all categories, the mean SIS was 9.58 cm; a different perception of the disease between the sexes was noted and also in the subgroups based on the ulcer's different etiology. In addition, the age of the affected patients influenced the SIS value.

CONCLUSIONS

PRISM is an easy and sensitive instrument to record information about the patient's expectations and suffering in order to improve the overall physician-patient relationship.

Adaptation and validation of the Spanish version of the Actinic Keratosis Quality of Life questionnaire

BACKGROUND AND OBJECTIVE

While there are questionnaires for evaluating the effects of skin cancer on patient quality of life, there are no specific questionnaires available in Spanish for evaluating quality of life in patients with actinic keratosis. The aim of this study was to translate and culturally adapt the Actinic Keratosis Quality of Life (AKQoL) questionnaire into Spanish.

PATIENTS AND METHODS

The original questionnaire was translated into Spanish following the guidelines for the cross-cultural adaptation of self-report measures. Several measures of general reliability and validity were calculated, including Cronbach α for internal consistency and the Spearman rank-order correlation coefficient and a Bland-Altman plot for test-retest reliability. To test concurrent validity, we used the Pearson correlation coefficient to measure the correlation between AKQoL and Skindex-29 scores.

RESULTS

The final version of the questionnaire was administered to 621 patients with actinic keratosis, who scored a mean (SD) of 5.25 (4.73) points (total possible score, 0-25). The Cronbach α reliability coefficient analysis was 0.84. The correlation between the mean (SD) score on the Skindex-29 (1.87 [4.07]) and on the AKQoL (1.97 [2.98] was 0.344 (P=.002, Spearman's rho), with a proportion of shared variance of 11.8%.

CONCLUSIONS

The translation, cross-cultural adaptation, and validation of the original AKQoL produced a reliable, easily understandable questionnaire for evaluating the impact of actinic keratosis on the quality of life of patients in our setting.

Translation, cross-cultural adaptation and validation of the Quality of Life Evaluation in Epidermolysis Bullosa instrument in Brazilian Portuguese

BACKGROUND

The Quality of Life Evaluation in Epidermolysis Bullosa (QoLEB) questionnaire was developed for use in English-speaking individuals.

OBJECTIVES

The aims of this study were to translate the QoLEB into Brazilian Portuguese, to culturally adapt it, and to verify its reliability and validity.

METHODS

The study followed the steps proposed by the World Health Organization, which include: translation; evaluation by a panel of experts and patients; back translation; and linguistic and cultural adaptation. All subjects were examined and assessed using the QoLEB and the Dermatology Life Quality Index (DLQI) or the Children's Dermatology Life Quality Index (CDLQI). Translation and cultural and linguistic adaptation were conducted by 10 patients, three translators, and the bilingual authors.

RESULTS

The population was composed of 40 children (mean age: 8,15 years) and 17 adults (mean age: 33 years). Among the children, eight had epidermolysis bullosa (EB) simplex (EBS), one had junctional EB (JEB), and 31 had dystrophic EB (DEB). In the adult group, four of the subjects had EBS, one had JEB, and 12 had DEB. Mean ± standard deviation (SD) scores on the QoLEB in children were 10.60 ± 7.13 in EBS subjects, 9.71 ± 7.87 in children with dominant DEB (DDEB), and 14.25 ± 9.67 in children with recessive DEB (RDEB). Mean ± SD scores in adults were 12.50 ± 9.95 in EBS subjects, 12.00 ± 5.83 in DDEB subjects, and 20.20 ± 9.21 in RDEB subjects. The QoLEB-BP (Brazilian Portuguese) showed high internal consistency (Cronbach's α = 0.88) and high test-retest reliability (intraclass correlation coefficient: 0.70), confirming the internal consistency and reproducibility of this Portuguese version. There were significant correlations between QoLEB scores and both CDLQI (Pearson's r = 0.688, P < 0.002) and DLQI (Pearson's r = 0.807, P < 0.001) scores.

CONCLUSIONS

Epidermolysis bullosa has marked impacts on the lives of EB patients and their families, which are strongly correlated with disease severity. The Brazilian Portuguese version of the QoLEB is validated and can be recommended for use in subsequent studies.

Prevalence and risk factors of depression in geriatric patients with dermatological diseases

Background

Although rarely life threatening, dermatological diseases may have a considerable influence on a patient's quality of life and psychological well-being. As with morbidity and mental distress from other chronic diseases, a skin disorder can be the one of the main causes of depression in the geriatric population.

Objective

To determine the prevalence of depression in elderly patients with dermatological disease in Korea and to identify factors associated with depression.

Methods

Patients over the age of 60 years with dermatologic diseases were solicited for a questionnaire survey. The Geriatric Depression Scale (GDS) was used to obtain a patient-based measurement of depression. Additionally, demographic information and medical history were collected.

Results

The questionnaire was completed by 313 patients (39.94% men, mean age 69.04 years, mean disease duration 3.23 years). Dermatological disease overall had a significant effect on patients' depression (χ²=177.13, p<0.0001), with a mean GDS score of 12.35 (out of 30). The patients who had a GDS score greater than 10 was 62.3% which indicated increased prevalence of mild to severe depression when compared to the general population among whom only 22.22% percent have GDS score greater than 10. In the univariate analysis, physical health, education level, and the presence of concurrent diseases were risk factors for geriatric depression. However, we did not find any demographic or disease related variables that were independent predictors of depression.

Conclusion

Geriatric patients with dermatological disease experience an increase burden of depression. Thus, it is important for clinicians to evaluate geriatric patients with dermatologic diseases for depression.

A Spotlight on Chemical Constituents and Pharmacological Activities ofNigella glanduliferaFreyn et Sint Seeds

Plants belonging to the Ranunculaceae family, and particularly their seeds, have been a hot research topic in numerous pharmacognosy laboratories.Nigella glanduliferaFreyn et Sint (NG) is one of the promising, but relatively insufficiently studied, plants from this family. In this review, we summarize the recently isolated chemical constituents from the seeds of this plant including alkaloids, flavonol glycosides, isobenzofuranone derivatives, saponins, terpenes, terpenoids, and fatty acids. We put also a spotlight on the recently studied therapeutic potentials of such amazing herb seeds as antidiabetes, melanogenesis inhibition, anticancer, anti-inflammatory, antithrombosis, and antiplatelet aggregation effects. Herein, we illustrate certain properties and potentials via selected examples, and thus we suggest more studies to confirm the therapeutic hypotheses, find out new compounds, and eventually to discover novel properties.

Quality of life in patients with skin diseases in central Saudi Arabia

Background

Previous national and international studies of quality of life (QoL) in patients with skin diseases have revealed different levels of QoL impairment. The aims of this study were to assess QoL in patients with skin diseases in central Saudi Arabia using the newly validated Skindex-16 instrument and to determine the association between QoL in patients with skin disease, sociodemographic data, and disease characteristics.

Methods

A cross-sectional study was conducted in 283 adult patients who visited the outpatient dermatology clinics of King Abdulaziz Medical City, Riyadh, Saudi Arabia, over 3 months. The patients were interviewed using a pretested Arabic version of the Skindex-16 to measure the effect of skin disorders on their QoL during the previous 7 days. Patient characteristics, medical history, and clinical findings were collected. Multiple linear regression analyses were used to relate the demographic and clinical characteristics to the percentage mean QoL score, and P ≤ 0.05 was considered to be statistically significant.

Results

QoL was good in 69% of the respondents, with a total percent mean score of 31.80 ± 20.16. The emotional domain was the most affected (mean percentage score 44.27 ± 27.06), followed by symptoms (31.45 ± 28.40) and functioning (14.61 ± 22.75). After adjustment for potential confounders, poorer QoL was significantly associated with female gender (P = 0.03), older age (P = 0.003), rural origin (P = 0.03), positive family history of the same lesion(s) (P = 0.01), shorter duration of ≤6 months (P = 0.02), generalized spread (P ≤ 0.02), and lack of isotretinoin treatment (P = 0.02).

Conclusion

. The QoL results in this study were generally more optimistic than those of many previous studies. This discrepancy may be due to biases in questionnaire responses or to cultural differences in experience of skin disease and perception of disability. Significant predictors of QoL were not the same for the three domains of the Skindex scale. Further studies of specific diseases and educational programs targeting patients at higher risk for QoL impairments are recommended.

Estudo da qualidade de vida nos pacientes com urticária crônica

FUNDAMENTOS: A urticária crônica compromete o doente por interferir nas atividades diárias, prejudicar a autoestima e as relações interpessoais. Os profissionais de saúde subestimam seu impacto na qualidade de vida dos doentes. OBJETIVOS: Avaliar a qualidade de vida com questionário específico e genérico. Compará-la entre os tipos clínicos de urticária crônica e avaliar se o angioedema piora a qualidade de vida. MÉTODOS: Participaram 62 doentes com urticária crônica, com sinais e sintomas da doença até 7 dias da consulta, que foram divididos em urticária crônica comum, urticária crônica física e urticária crônica mista. RESULTADOS: Observou-se predominância de mulheres (72,6%), idade média de 39,8 anos, angioedema associado em 75,8% dos doentes. Apresentaram mais angioedema doentes com urticária crônica comum (p=0,011) e mulheres (p=0,024). Quanto aos tipos clínicos, 32,3% apresentaram urticária crônica comum, 27,4% urticária crônica física e 40,3% urticária crônica mista. O escore médio total do questionário específico foi 10,4. No questionário específico, os domínios mais comprometidos foram "Sintomas e sentimentos" e "Atividades diárias", e, no SF-36, "Aspectos físicos" e "Vitalidade". Houve comprometimento da qualidade de vida nas mulheres, nos doentes com até 30 anos, em primeira consulta, nos mais escolarizados, naqueles com até 1 ano de doença e naqueles com angioedema. CONCLUSÃO: A urticária crônica compromete a qualidade de vida medida pelos questionários específico e genérico. Não houve diferença estatisticamente significante na qualidade de vida entre os tipos clínicos. A presença do angioedema conferiu pior qualidade de vida aos doentes. Houve correlação estatisticamente significante entre os escores do questionário específico e do questionário genérico.

'Perfect skin', the media and patients with skin disease: a qualitative study of patients with acne, psoriasis and atopic eczema

The relationship of skin disease with societal ideals of beauty, and the role of the media in this relationship, has not previously been researched. The overall objective of this study was to explore the psychological effects of skin disease. The theme of the ideal of perfect skin and the role of the media in generating this ideal arose via an inductive study methodology and was explored in the context of respondents’ psychological morbidity. A qualitative study, 62 semi-structured interviews were conducted with respondents with acne, eczema or psoriasis recruited from both general practice and specialist dermatology practice in an Australian regional city. Interviews were audiotaped, transcribed and subjected to thematic analysis employing a process of constant comparison in which data collection and analysis were cumulative and concurrent. The themes of perfect skin, societal ideals and media influence emerged from this iterative process. Respondents identified a societal ideal of flawless skin, largely mediated by media portrayals of perfection. Failure to meet this ideal precipitated psychological morbidity in female, but not male, respondents. An appreciation of the pervasive pressures of society and media upon females with skin disease may inform management strategies, particularly psychological management strategies, in patients with skin disease.

Influência das dermatoses na qualidade de vida do portador de diabetes mellitus

O diabetes mellitus (DM) predispõe às dermatoses associadas à própria afecção, infecções cutâneas, reações medicamentosas ou ao pé diabético. Este estudo, analítico, transversal e quantitativo, parte da hipótese de que as dermatoses influenciam a qualidade de vida dos portadores de DM e foi desenvolvido no Programa de Saúde da Família (PSF) Odilom Lacerda, em Planura (MG). A amostra tem 47 (100%) pacientes portadores de DM e cadastrados no programa HIPERDIA. A coleta de dados foi feita durante a consulta pelo dermatologista, que aplicou a anamnese direcionada para dermatopatias e qualidade de vida e um formulário para a avaliação subjetiva da influência das dermatoses na qualidade de vida. A análise dos dados foi numérica e percentual, quanto às manifestações provocadas pela dermatose no comprometimento da qualidade de vida, segundo o próprio paciente. Para a mensuração dos resultados, foram estabelecidos os critérios de frequência: alta (80 a 100%), média (50 a 79%), baixa (1 a 49%) e nula às situações inexistentes. Todos os pacientes (47-100%) apresentaram dermatoses e demonstraram que influenciam a sua qualidade de vida, com média frequência no que se refere ao ressecamento e sensação dolorosa na pele (24-51%) e baixa frequência, especialmente a dificuldade na higienização pessoal (19-40,3%) e a interferência no relacionamento interpessoal com parentes ou amigos (18-38,2%).

Quality of life measurements in epidermolysis bullosa: tools for clinical research and patient care

Quality of life (QOL) evaluation in epidermolysis bullosa (EB) has important applications in clinical management, patient advocacy, clinical research, and the development of new treatments. Several new quantitative and qualitative QOL measurement tools were developed recently, providing insight into the impact EB has on individuals and their family members. Selection of the most appropriate QOL tool for patients who have EB depends on not only the type of information required but also the general or specific cohort being examined. EB-specific quantitative tools possess the highest level of content validity and statistical accuracy. However, generic dermatologic tools may also be appropriate in some circumstances. Overall, QOL evaluation in EB is still a developing area of research that may help improve patient management and assess emerging treatment modalities for their efficacy in improving the QOL of patients with EB.

Burden of skin diseases

Skin diseases are among the most common health problems worldwide and are associated with a considerable burden. The burden of skin disease is a multidimensional concept that encompasses psychological, social and financial consequences of the skin disease on the patients, their families and on society. Chronic and incurable skin diseases, such as psoriasis and eczema, are associated with significant morbidity in the form of physical discomfort and impairment of patients' quality of life; whereas malignant diseases, such as malignant melanoma, carry substantial mortality. With the availability of a wide range of health status and quality-of-life measures, the effects of most skin diseases on patients' lives can be measured efficiently. The aim of this review is to present some of the published data in order to highlight the magnitude of the burden associated with some common skin diseases and also to suggest ways to quantify this burden of skin disease.

Experiences of appearance-related teasing and bullying in skin diseases and their psychological sequelae: results of a qualitative study

Acne, psoriasis and atopic eczema are common diseases and have been consistently associated with adverse psychological sequelae including stigmatization. Being teased on the basis of appearance has been associated with psychiatric morbidity in children and adolescents. The objective of this qualitative study was to explore the experiences of teasing and bullying in patients with acne, psoriasis and eczema, and the role of appearance-related teasing and bullying as mediators of psychological morbidity in these patients. Data collection consisted of 62 in-depth semi-structured interviews with patients with acne, psoriasis or atopic eczema recruited from both specialist dermatology and general practices. Data analysis was cumulative and concurrent throughout the data collection period reflecting a grounded theory approach. Analysis followed the analytic induction method, allowing themes to emerge from the data. Teasing, taunting or bullying was a considerable problem for a significant minority of acne, psoriasis and atopic eczema participants. Themes that emerged were the universally negative nature of the teasing, the use of teasing as an instrument of social exclusion, and as a means of establishing or enforcing power relationships, teasing related to contagion and fear, the emotional and psychological sequelae of teasing and the theme of 'insensate' teasing. For those who had suffered teasing or bullying, this was causally linked in respondents' accounts with psychological sequelae, especially self-consciousness and effects on self-image and self-esteem. Experiences of teasing and bullying were found to have principally occurred during the adolescence of participants and the perpetrators were other adolescents, but there were findings of respondents with psoriasis also having been subjected to ridicule or derogatory remarks by health professionals. Teasing, taunting and bullying may represent an underappreciated source of psychological morbidity in children and adolescents with these common skin diseases.

The Dermatology Life Quality Index 1994-2007: a comprehensive review of validation data and clinical results

BACKGROUND

The Dermatology Life Quality Index (DLQI) is one of the most widely used dermatology-specific quality of life instruments. Over the last 5 years there has been great interest in its use.

OBJECTIVES

To collect and present all information regarding the technical properties and the clinical use of the DLQI from the date it was published to the end of 2007 for use as a single source of reference.

METHODS

A detailed literature search was conducted using electronic reference databases and the DLQI library in the Department of Dermatology, Cardiff University. All publications mentioning any aspect of the DLQI, from the time of its development to the end of 2007, were identified and the data concerning the DLQI in terms of its psychometric analysis, and use in clinical trials, epidemiological studies and health services research, were extracted and tabulated with all the relevant references.

RESULTS

In total, 272 full articles which have included the DLQI were reviewed. Studies described in these articles were divided into five main categories: psychometric studies, descriptive/epidemiological studies, drug (topical and systemic) trials, clinical practice research, and therapeutic interventions. The DLQI has been used in 33 different skin conditions in 32 countries and is available in 55 languages. Psychometric aspects of the DLQI such as validity, reliability, responsiveness to change, factor structure, and minimal important difference were described in 115 studies. The DLQI has been used in 33 studies assessing the effectiveness of 14 different types of therapeutic interventions and in 37 studies evaluating nine types of clinical practice research. Sixty studies have used it alone or in parallel with other instruments as an outcome measure in clinical trials of 18 systemic drugs while 22 studies have used it in 14 different topical drug trials. The DLQI has also been used in 27 multinational studies.

CONCLUSIONS

During the last 14 years there has been a gradual increase in the international use of the DLQI. The brevity and simplicity of use of the DLQI has resulted in its popularity both in clinical practice and in research. However, there are various issues in particular regarding its unidimensionality, differential item functioning, and minimal clinically important difference, which require further research. This article should facilitate the work of potential users of the DLQI by providing a readily available source of references for different aspects of the DLQI.

Effect of melasma on quality of life in a sample of women living in southern Brazil

BACKGROUND

Melasma can cause a significant effect on individual emotional well-being. Melasma Quality of Life Scale (MELASQoL) is a specific questionnaire elaborated to assess the burden of melasma on patient's quality of life.

OBJECTIVE

To evaluate the clinical aspects, severity and the influence of melasma on daily living of a sample of Brazilian women.

METHODS

Cross-sectional study that enrolled 85 women with melasma older than 15 years of age. Trained investigators asked 55 questions to collect epidemiological and clinical data. The disease severity was clinically assessed using Melasma Area and Severity Index (MASI). Patients answered the Portuguese version of 10-item MELASQoL scale without coaching.

RESULTS

The mean +/- SD age was 41.1 +/- 6.8 years, and the mean +/- SD of MELASQoL score was 37.5 +/- 15.2 (median, 35). Patients with previous psychiatric diagnosis had significantly higher MELASQoL scores (mean, 42.8; SD, 13.6) than patients without this antecedent (mean, 35.4; SD, 15.4; P < 0.05). Patients with less than 8 years of school attendance also had significantly higher MELASQoL score (mean, 44; SD, 16.9) than more graduated ones (mean, 34.4; SD, 13.5; P < 0.05). The mean +/- SD MASI was 10.6 +/- 6.6 (median, 10.2). There was no correlation between MASI and MELASQoL.

CONCLUSIONS

This study confirms that MELASQoL-BP is easy to administer, adds important information about the impact of melasma on South American women's life and, finally, contributes to building evidence on the validity, reliability and cultural adaptation of the Portuguese language MELASQoL version.

Relação entre de prurido e qualidade de vida de pacientes em hemodiálise

FUNDAMENTOS: O prurido é um sintoma freqüente nos pacientes em hemodiálise. Tem etiologia não totalmente esclarecida e difícil manejo, o que piora de modo considerável a qualidade de vida dos doentes. OBJETIVOS: Avaliar o grau de prurido e sua influência na qualidade de vida dos pacientes renais crônicos em hemodiálise. MÉTODOS: Estudo transversal com pacientes renais crônicos em hemodiálise no Complexo Hospitalar Santa Casa de Porto Alegre, que apresentassem prurido sem outras dermatoses. Utilizou-se a escala análoga visual para mensuração do grau de prurido e o questionário do Índice de Qualidade de Vida para Dermatologia. RESULTADOS: Dos 200 pacientes avaliados, 69 (34,5%) apresentaram prurido, dos quais 16 (23%) de grau leve, 39 (56,5%) moderado e 14 (20,2%) grave. Quando analisada a qualidade de vida, verificou-se que em 14 (20,3%) não houve influência do prurido na qualidade de vida. Entretanto, para 26 pacientes (37,4%), o prurido teve um pequeno efeito, em nove (13%) houve efeito moderado, 13 (18,8%) foram afetados de maneira grave e em sete (10,1%) houve influência extremamente grave. CONCLUSÕES: Neste estudo, 57% dos indivíduos não demonstraram alterações importantes na qualidade de vida relacionadas ao prurido, mas um número significativo estava na faixa de muito e extremamente alterado, o que denota a necessidade de atenção ao tratamento deste sintoma neste grupo de pacientes.

Impacto na qualidade de vida em pacientes com hanseníase: correlação do Dermatology Life Quality Index com diversas variáveis relacionadas à doença

FUNDAMENTOS: A hanseníase é doença infectocontagiosa crônica causada pelo Micobacterium leprae. Caracteriza-se por acometimento dermatoneurológico, variando em espectro entre dois pólos estáveis. Apesar de curável, ainda representa relevante problema de saúde pública, sendo o Brasil o segundo país mais endêmico do mundo. Sua maior morbidade associa-se aos estados reacionais e ao acometimento neural, podendo causar incapacidades físicas permanentes que comprometem significativamente a qualidade de vida dos pacientes, com auto-estigmatização e vergonha. OBJETIVO: Avaliar o grau de comprometimento da qualidade de vida nos pacientes com hanseníase. MÉTODOS: Estudo observacional com correlação entre variáveis clínicas de gravidade da doença e questionário de avaliação da qualidade de vida: Dermatology Life Quality Index. RESULTADOS: Dos 40 pacientes avaliados, a maioria apresentou comprometimento da qualidade de vida de grave a muito grave segundo score obtido no Dermatology Life Quality Index. As variáveis analisadas individualmente também mostraram correlação de gravidade com o número de pontos obtido. CONCLUSÃO: A hanseníase causa sofrimento que ultrapassa a dor e o mal-estar estritamente vinculados ao prejuízo físico, com grande impacto social e psicológico, justificando tanto avanços para abordagem multidisciplinar ao paciente quanto a necessidade de ações de saúde que visem ao controle da doença.

Suffering in psoriasis patients: its relation with illness severity and subjective well-being

OBJECTIVE

The aim of the present study was to explore the relationship among subjective illness impact, subjective well-being, and psoriasis severity as assessed by dermatologists. Furthermore, subjective well-being of psoriasis patients was compared to available norm data.

METHODS

Fifty-nine psoriasis patients participated in this study. The following measures were administered: (a) the Pictorial Representation of Illness and Self Measure - Revised (PRISM-R), yielding Self-Illness Separation (SIS), and Illness Perception Measure (IPM); (b) subjective health status; (c) life satisfaction, and (d) psychological well-being. In addition, the Psoriasis Area and Severity Index (PASI) was determined by dermatologists.

RESULTS

Psoriasis patients scored significantly below the norm data on subjective health status and psychological well-being. No differences were found concerning life satisfaction. PASI failed to correlate significantly with any of the disease impact and subjective health measures. Neither did SIS correlate significantly with any of the subjective health measures, whereas IPM was negatively associated with subjective health status, life satisfaction, and psychologic well-being. In a regression analysis with PASI as the dependent measures, none of the subjective health measures showed up as a relevant predictor.

CONCLUSION

In comparison with the norm data, psoriasis patients report less subjective health status and well-being whereas their life satisfaction is not affected. There is no clear association among illness impact, subjective well-being, and illness severity as assessed by dermatologists.

Pigmentary disorders in Western countries

Countries in the so-called "Western" world, especially in Europe, witnessed a dramatic change in ethnic backgrounds of their populations starting in the last decennia of the last century. This had repercussions on various aspects of our society, including medical practice. In dermatology for instance, pigmentary disorders are seen more often, and the clinical pictures and their impact on patients are different from what doctors and researchers are used to and trained for. In this article, the experience from the Netherlands Institute for Pigment Disorders and the multicenter designed Netherlands guideline on vitiligo are described and the importance of the patient's point of view, as can be measured by patient reported outcomes like quality of life, is emphasized.

Quality of life is severely compromised in adult patients with atopic dermatitis in Brazil, especially due to mental components

PURPOSE

to measure the quality of life (QoL), either by a specific dermatology or generic self applied questionnaire, in Atopic dermatitis adult Brazilian patients, looking for selected affected groups.

METHODS

We studied the quality of life of 75 Brazilian ambulatory adults with atopic dermatitis using two types of self-answered instruments: a quality of life generic questionnaire (SF-36) and a 10-item Dermatology Life Quality Index (DLQI) questionnaire. All patients had been treated for at least 6 months, and their disease status was determined by Eczema Area and Severity Index scores.

RESULTS

Quality of life and disease control were found to be related but with low scores both in DLQI (r(2)=0.26) and in SF-36 (r(2)=0.20), but with greater correlation for SF-36 mental components. Using the 75% percentile distribution of SF36 mean score and the 75% value of disease severity score, we sorted patients into four groups: I, referring good QoL and mild atopic disease (14/75), II, referring bad QoL and with mild atopic disease (19/75), III referring good QoL despite severe atopic disease (5/75) and IV referring bad QoL and severe atopic disease (37/75); all groups presented similar age, education, family income and time of disease progression. There was a higher frequency of women in group II, but without sleep disturbance or increased pruritus, which was present in group IV, with intense itching and sleep disturbances. Analyzing the physical or mental components of the SF36 generic test, discrepant groups II and III presented higher differences related to the mental components of the test, which was also related to DLQI scores, with a similar distribution for the 2 groups and a higher relation to the mental component of the generic test.

CONCLUSION

The quality of life is affected in adult atopic patients, both related to disease severity and also to mental components, but with diverse effects in patient subgroups. Our data show some components that may mask the exact relationship between QoL results and disease severity.

[Health-related quality of life in dermatologists compared to other physicians]

BACKGROUND

According to recent studies, there may be differences in quality of life for physicians depending on gender and field of medicine. Presently, there are hardly any data with respect to health-related quality of life in dermatologists.

METHODS

Using the SF-36 Health Survey, 112 dermatologists and 113 physicians in other fields of medicine were studied in a cross-sectional study.

RESULTS

Dermatologists' mental health level averaged lower than their physical health level (chi2=28.49; p<.001). The mental and physical health level were higher in female dermatologists than in their male colleagues (e.g., GH: chi2=6.15; p<.05 and MH: chi2=6.83; p<.05). These findings are the opposite of results in other medical specialists. The differences between mental and physical health dimensions on the one hand, and between women and men on the other hand, were found in all age groups.

CONCLUSIONS

In comparison to other medical specialists, dermatologists differ only slightly in their health-related quality of life. Therefore, it may be advisable to implement preventive measures concerning their comparatively low mental health status.

Validation of a melasma quality of life questionnaire for Brazilian Portuguese language: the MelasQoL-BP study and improvement of QoL of melasma patients after triple combination therapy

BACKGROUND

Pigmentation disorders, such as melasma, greatly influence the quality of life (QoL) of affected individuals who usually consider the disorder to be more severe than the objective clinical scores. Several instruments have been successfully developed to evaluate QoL. However, they must be adapted to the target population in terms of language and cultural diversity. The first, specific QoL questionnaire for melasma (MelasQoL) was developed for English speaking patients.

OBJECTIVES

To validate the Brazilian Portuguese version of the MelasQoL evaluation questionnaire for patients with melasma (MelasQoL-BP) and to assess the impact of treatment with a triple combination cream (hydroquinone, fluocinolone acetonide and tretinoin) on the QoL of patients with moderate-to-severe melasma.

METHODS AND RESULTS

Three hundred individuals from the five Brazilian geographic regions took part in this multicentre study. Their mean age was 42 years and skin phototype distribution was: type II 7.0% of patients, III 23.7%, IV 42.7% and V 22.7%. Melasma Area and Severity Index (MASI), MelasQoL-BP and the short version of the QoL assessment instrument from the World Health Organization (WHOQOL-BREF) were used to assess melasma severity and QoL at baseline. MelasQoL-BP was previously translated and culturally adapted from the English version, with participation of the authors and according to the standards of the World Health Organization (WHO). From the original sample, we randomized150 volunteers to treat melasma and repeated the evaluation after 8 weeks. The analysis of the MelasQoL-BP baseline answers demonstrated an important impact of the disease on skin appearance (65% of patients were bothered all the time or most of the time), frustration (55%), embarrassment (57%) and influence of the disease on interpersonal relationships (42%). Forty-three per cent of patients felt not attractive or even dirty due to their skin condition. MelasQoL-BP results showed significant internal consistency (Cronbach's alpha coefficient 0.919; P < 0.001) and good correlation with MASI scores. After treatment, the global assessment showed good or excellent results in 91.4% of the patients. The clinical outcome was not associated with the initial MASI score (P = 0.814; chi-square), skin colour (P = 0.449; probability ratio) or skin pigmentation (P = 0.814; chi-square). There was also a significant reduction on MelasQoL-BP scores (Wilcoxon test; P < 0.001) after treatment, with the mean +/- SD results shifting from 44.4 +/- 14.9 at baseline to 24.3 +/- 15.5 after treatment. The analysis of the MelasQoL-BP before and after treatment showed an important effect of the impact of treatment on a number of QoL measures. Of note, skin appearance (69.8 vs. 10.1% of patients were bothered all the time or most of the time, respectively), frustration (59.7% vs. 12.2%, respectively), embarrassment (56% vs. 9.3%, respectively) and influence of the disease on interpersonal relationships (35.3% vs. 5.8%, respectively) were greatly improved.

CONCLUSIONS

This study demonstrates that MelasQoL-BP is a valid instrument and can be used to evaluate the quality of life and response to melasma treatment in Brazilian patients. The triple combination treatment produced significant results, regarding both clinical severity and quality of life.

Psychosocial effects of vitiligo

A limited number of studies have paid attention to the psychosocial well-being of patients affected with vitiligo. We review the psychosocial effects of vitiligo, how patients deal with them and the psychiatric morbidity in vitiligo patients. Given the appreciable comorbidity, it is important to consider these observations in the management of patients, for example in patient-physician interaction but also in treatment strategies and evaluation of treatments. The effects of the psychological state on the disease itself together with the potential therapeutic implications are reviewed. Based on these data, we suggest how to further improve patient's management.

Does enough quality of life-related discussion occur during dermatology outpatient consultations?

BACKGROUND

Dermatologists' assessments of how their patients' lives are affected by the skin disease are of importance for informing clinical decisions. However, there is no information about how often quality of life (QoL) issues are discussed in outpatient consultations.

OBJECTIVE

To examine the relationship between the extent of QoL-related discussion during dermatology outpatient consultations, and the current impact of the disease on patients' lives.

PATIENTS AND METHODS

A total of 238 consultations were observed in a teaching dermatology outpatient department for QoL-related discussion initiated by either the clinician or the patient. Following the consultation, all patients were posted a Dermatology Life Quality Index (DLQI) questionnaire to complete and return within 1 week.

RESULTS

QoL discussion was absent in 40% of consultations. Consultants initiated the fewest QoL discussions with patients, and nurses the most (P < 0.0001). One hundred and twenty-eight (54%) patients returned the DLQI, 114 (48%) of which were evaluable. The mean score was 5.6, SD +/- 6.6, median 3, range 0-29. The mean DLQI score for the patients with whom there was no QoL discussion was 4.0 +/- 4.7, n = 55, compared with the mean DLQI score for patients with whom QoL was discussed 6.8 +/- 7.2, n = 59 (P < 0.001).

CONCLUSION

This study demonstrates that little information concerning QoL is elicited during dermatology outpatient consultations.
