Clinical characteristics and quality of life in seborrheic dermatitis patients: a cross-sectional study in China.

BACKGROUND: Seborrheic dermatitis (SD) is a common, chronic, inflammatory skin disorder, yet few studies have reported its clinical characteristics, or addressed its effect on quality of life (QoL). This study assesses the clinical characteristics and QoL of SD patients in China. It also identifies the clinical, demographic and environmental factors that may influence QoL. METHODS: Three hundred twelve SD outpatients from 9 hospitals completed a survey. QoL was measured with the dermatology-specific instrument Skindex-29. We collected social demographic characteristics and disease severity, and conducted logistic regression to determine the factors associated with QoL impairment. RESULTS: 67.3% of the patients were females. The mean Skindex-29 overall score was 33.97 (SD = 20.55). The breakdown was 40.79 (SD = 24.24) for emotions, 32.83 (SD = 19.84) for symptoms and 28.3 (SD = 23.24) for functioning. 48.1% had severe emotional problems. Logistic regression analysis showed that BMI less than 25 (OR = 0.223; 95% CI: 0.072-0.692; P = 0.009), skin disease-related hospitalization (OR = 6.882; 95% CI:1.767-26.795; P = 0.005), environmental PM 10 levels above 120 µg/m3 (OR = 3.386; 95% CI: 1.253-9.15; P = 0.016) and severe disease conditions (OR = 4.438; 95% CI:1.26-15.626; P = 0.02) were risk factors for severe emotional impairment. Moreover, skin disease-related hospitalization (OR = 6.057; 95% CI:1.351-27.149; P = 0.019), environmental PM 10 levels between 70 and 120 µg/m3 (OR = 6.317; 94% CI: 1.704-23.42; P = 0.006), moderate (OR = 2.388; 95% CI: 1.272-4.487; P = 0.007) and severe disease conditions (OR = 5.732; 95% CI: 1.838-17.88; P = 0.003) were each risk factors for overall severe impairment. CONCLUSION: In China, nearly half of SD patients had severely emotional problems. Disease severity, BMI, dermatologic hospitalization, and ambient PM 10 levels are each risk factors for QoL impairment in SD patients. These implications are alarming, and warrant public health attention in SD disease management.

Comparison of different regimens of pimecrolimus 1% cream in the treatment of facial seborrheic dermatitis.

BACKGROUND: Pimecrolimus 1% cream has already been proved to be an effective and safe alternative to treat seborrheic dermatitis. However, the treatment periods were inconstant in previous studies. OBJECTIVE: To evaluate the comparative efficacy of pimecrolimus 1% cream with different regimens for the treatment of facial seborrheic dermatitis. METHOD: Thirty patients with facial seborrheic dermatitis were enrolled and randomly distributed to three groups. Patients of Group 1 were treated with topical pimecrolimus cream 1% twice daily for 2 weeks and then a moisturizer cream twice daily for 2 weeks. Patients of Group 2 were treated with pimecrolimus cream 1% twice daily for 2 weeks and then once daily for another 2 weeks. Patients of Group 3 had a consecutive course of pimecrolimus cream 1% twice daily for 4 weeks. Objective symptoms, subjective symptoms, and dermatology life quality index (DLQI) were measured at weeks 0, 2, 4, and 6. RESULTS: At week 4, the clinical severity scores of all three regimens significantly decreased (P<.01). The improvement of total severity score in Group 3 was more remarkable than groups 1 and 2 (both P<.05). This effect was maintained until the end of the study in Group 3. Life quality of all three groups was significantly improved at week 4 (P<.001), while there was no statistical difference on the improvement of life quality among three groups. CONCLUSION: We recommend pimecrolimus 1% cream could be applied twice a day for 4 weeks to treat seborrheic dermatitis.

Quality of life and emotional state in chronic skin disease.

The aim of this study was to evaluate the associations between chronic inflammatory skin conditions and patients' emotional state and quality of life. The following self-rated questionnaires were used: Emotional State Questionnaire, a self-report scale assessing depression and anxiety symptoms; Dermatology Life Quality Index (DLQI); and RAND-36, a measure of health-related quality of life. The study group comprised 40 patients with psoriasis, 40 with eczema, 40 with acne, 15 with seborrhoeic dermatitis and 40 healthy controls. Patients with chronic skin diseases had lower DLQI and lower RAND-36 physical functioning scores, more perceived physical limitations and pain, and lower emotional well-being and general health ratings compared with the control group. In conclusion, chronic skin diseases are associated with symptoms of emotional distress, in particular insomnia and general anxiety.

Psychologic factors in the development of facial dermatoses.

In medical literature, as well as in daily practice, some common facial dermatoses are considered to be influenced or triggered by emotional factors. The main damager is stress, but depression and anxiety may play a role, among other factors. Some patients may experience a vicious cycle: Their facial dermatosis is triggered or worsened by stress, and in turn, the exacerbation itself is a major stressogenic stimulus. It appears that clinical wisdom and experience preceded clinical investigation in this field. Although patients testify that their emotional state may sometimes influence their facial condition, only limited experimental data exist so far, and only a few facial dermatoses were investigated.

Quality of life assessment of patients with scalp dermatitis using the Italian version of the Scalpdex.

The aim of this study was to assess quality of life in patients with scalp dermatitis using the Italian version of the Scalpdex, and to validate the instrument in Italian. The survey was conducted in outpatients with psoriasis, seborrhoeic dermatitis, alopecia, or follicular lichen. Data were completed on 194 patients, 78% of whom had psoriasis. Scalpdex scores were always higher in women than in men, and in younger people compared to elderly people. The most frequent items were: being ashamed, embarrassed, bleeding scalp, feeling self-conscious, bothered that the condition is incurable, having the choice of colour of clothes affected, having a negative effect on daily life. The Italian Scalpdex showed good internal consistency, test-retest reliability, convergent validity, and responsiveness. In conclusion, the Italian version of the Scalpdex is a useful instrument to measure quality of life in patients with a scalp condition.

Psychiatric comorbidities and alexithymia in patients with seborrheic dermatitis: a questionnaire study in Turkey.

OBJECTIVE: The aim of the study was to determine the levels of anxiety, depression, and obsessive-compulsive symptoms in patients with seborrheic dermatitis (SD) compared with healthy subjects. Additionally, we aimed to investigate the presence of alexithymia among patients and its association with these psychiatric comorbidities. METHODS: A total of 117 consecutive adult patients (66 male, 51 female) with SD and 95 age- and gender-matched healthy controls selected from the community (46 male, 49 female) were enrolled in the study. The demographic characteristics of the patients were recorded. The clinical severity of the disease was assessed according to the Seborrheic Dermatitis Area and Severity Index (SDASI) scoring system. Both patients and controls were evaluated by the validated Turkish versions of the Hospital Anxiety and Depression Scale (HADS), Maudsley Obsessive Compulsive Inventory (MOCI), and Toronto Alexithymia Scale (TAS-26). RESULTS: There were no statistically significant differences between the patient and control groups regarding the mean scores of depressive or obsessive-compulsive symptoms or alexithymia (all p > 0.05). However, anxiety scores in patients with SD were higher than in controls (p = 0.001). No significant relationship was present between anxiety and disease severity nor disease duration (p > 0.05). Thirty-eight patients with high anxiety scores were found to be more alexithymic (p = 0.000). CONCLUSION: SD is one of the inflammatory skin disorders that is known to be triggered or aggravated by stress. However, little scientific evidence exists to confirm this view. In addition, very limited data are available about the presence of the personality profiles leading to emotional dysregulation such as alexithymia and concurrent psychiatric disorders in patients with SD. Our study showed that anxiety levels were significantly higher in patients with SD compared with healthy controls but there was no significant association with alexithymia, depression, or obsessive-compulsive symptom levels. Dermatologists should be particularly vigilant to the possibility of concurrent psychiatric morbidity in patients with SD in order to improve patients' well-being.

[Dermatology, cosmetic and well-being]. / Dermatologie, cosmétique et bien-être.

BACKGROUND: To the extent that they help improve our appearance, cosmetics can affect how we relate to ourselves and to others, and as such can improve quality of life. Such benefits may be objectively demonstrated using validated methods and quality-of-life scales. GOAL: The aim of this review is to assess the effects of cosmetics on well-being in various situations based on studies using objective measurement methods. METHOD: Literature review. RESULTS: In pathological settings, the use of cosmetics can significantly improve the quality of life and well-being of patients, resulting in better acceptance of their disease and better therapeutic compliance. The use of cosmetics has also been shown to exert positive effects on self-esteem and social relations. A growing body of studies also demonstrates the beneficial effects of cosmetics on well-being under normal physiological conditions. DISCUSSION: Today, the effects and benefits of cosmetics can be measured objectively using quality-of-life scales, allowing initiation of actions for the rediscovery of well-being and self-esteem.

Retrospective, observational study on the effects and tolerability of flutamide in a large population of patients with acne and seborrhea over a 15-year period.

The long-term effects and tolerability of flutamide (Flu) in women with acne and seborrhea were evaluated. Over the 15-year period, which spans from January 1991 to January 2006, a total of 230 Caucasian women with acne, 211 of which also with seborrhea, received yearly reducing doses (250, 125, and 62.5 mg/day) of Flu alone or combined with oral contraceptive for a period varying from 3 to 6 years and more. Clinical and endocrine evaluations were performed half-yearly and yearly, respectively, in the first 3 years of the study, and yearly in the following years. Liver function evaluations were performed quarterly. Both the groups of patients under Flu therapy showed a similar, marked decrease in acne and seborrhea scores after 6 months of treatment compared with basal values. The maximum drug effect was observed after 1 year, and it was maintained during the following years of treatment. Androgens were strongly suppressed during treatment. During the first year of treatment with 250 mg/day, 4.8% of patients interrupted the study due to hepatic disorders. During the following years on the 125 and 62.5 mg/day doses, no transaminase elevation was observed. The study supports very low-dose Flu as a first-line therapy for women with acne and seborrhea.

Quality of life in patients suffering from seborrheic dermatitis: influence of age, gender and education level.

Seborrheic dermatitis is a common inflammatory skin condition occurring mostly on the face, scalp and chest. Despite its high frequency, the impact of seborrheic dermatitis on patients' quality of life (QoL) has not been studied well so far. The objectives of this study were to analyse how seborrheic dermatitis affects the patients' QoL and which socio-economic factors could modulate QoL in these patients. A total of 3000 patients with seborrheic dermatitis and/or dandruff were enrolled into the study. All participants were divided into subgroups according to gender, age and education level. A specially designed questionnaire with demographic and clinical details of patients as well as Dermatology Life Quality Index (DLQI) was completed during a patient visit in an outpatient clinic. Data were collected by local dermatologists who were instructed regarding the inclusion and exclusion criteria and the questionnaires were sent back to us upon completion. The mean DLQI score for all patients was 6.92±5.34 points. Patients with dandruff had significantly better QoL than subjects with seborrheic dermatitis (5.34±4.67 points vs. 7.73±5.3 points, respectively; P<0.001) or individuals with dandruff plus seborrheic dermatitis (7.54±5.6 points, P<0.001). In addition, women, younger patients and subjects with higher educational level were more affected than the rest of the patients. Seborrheic dermatitis had significant, negative influence on patients' QoL. Observed discrepancies between subgroups could be explained by different roles played by different patient subgroups in the society. DLQI can be successfully used for the assessment of QoL in large populational studies.

Categorization of Skindex-29 scores using mixture analysis.

BACKGROUND: Although the Skindex-29 is among the most commonly used health-related quality of life instruments in dermatology, the interpretation of obtained scores is not well documented. OBJECTIVE: To create categories of the scores of the Skindex-29. METHODS: The Skindex-29 scores of454 Italian patients with 6 distinct skin diseases from a specialized center were analyzed using mixture analyses. The validity of the obtained categorizations was tested. RESULTS: Mixture analysis showed 4 distinct components (categories) for the emotion and functioning scale and 5 for the symptom scale. The total Skindex-29 score was categorized into 4 levels. As expected, patients with inflammatory diseases had higher levels of impairment, those with vitiligo and alopecia areata had low symptom levels and those with nevi were predominantly located in the lower categories for each of the scales. CONCLUSION: The proposed categories of the Skindex-29 may ease the interpretation of obtained continuous scores.

Patient experiences with oily skin: the qualitative development of content for two new patient reported outcome questionnaires.

OBJECTIVE: To develop the content for two new patient reported outcome (PRO) measures to: a) assess the severity of symptoms; and b) the impact of facial skin oiliness on emotional wellbeing using qualitative data from face to face, and internet focus groups in Germany and the US. METHODS: Using input from initial treatment satisfaction focus groups (n = 42), a review of relevant literature and expert clinicians (n = 3), a discussion guide was developed to guide qualitative inquiry using Internet focus groups (IFGs). IFGs were conducted with German (n = 26) and US (n = 28) sufferers of oily skin. Questionnaire items were generated using coded transcript data from the focus groups. Cognitive debriefing was conducted online with 42 participants and face to face with an additional five participants to assess the comprehension of the items. RESULTS: There were equal numbers of male and female participants; mean age was 35.4 (SD 9.3) years. On average, participants had had oily skin for 15.2 years, and 74% (n = 40) reported having mild-moderate acne. Participants reported using visual, tactile and sensory (feel without touching their face) methods to evaluate the severity of facial oiliness. Oily facial skin had both an emotional and social impact, and was associated with feelings of unattractiveness, self-consciousness, embarrassment, irritation and frustration. Items were generated for a measure of oily skin severity (Oily Skin Self-Assessment Scale) and a measure of the impact of oily skin on emotional well-being (Oily Skin Impact Scale). Cognitive debriefing resulted in minor changes to the draft items and confirmed their face and content validity. CONCLUSION: The research provides insight into the experience of having oily skin and illustrates significant difficulties associated with the condition. Item content was developed for early versions of two PRO measures of the symptoms and emotional impact of oily facial skin. The psychometric validation of these measures reported elsewhere.

[Stress and seborrheic dermatitis]. / Stress et dermatite séborrhéique.

BACKGROUND: It is widely accepted that episodes of seborrheic dermatitis are frequently induced by stress, as stated in all general reviews of the subject. However, there have been no studies to confirm this view. PATIENTS AND METHODS: This prospective study was performed in two phases. An initial questionnaire collected information on patients' identity, somatic and psychiatric history and seborrheic dermatitis characteristics. Information on triggering episodes was sought by means of an open question and patients were then asked if they had experienced stress during the week or month prior to the active episode. A second questionnaire containing the same questions (except for history) was completed four months later. The two questionnaires contained psychopathological evaluation scales designed to detect symptoms of anxiety and depression among patients (HAD: Hospital Anxiety and Depression scale; Beck; STAI: State-Trait Anxiety Inventory) and determine their perceived stress (PSS: Perceived Stress Scale by Cohen and Williamson). RESULTS: Eighty-two patients (36 women and 46 men) were included in the study. 82% of patients presented involvement of scalp, 33% of the face, 19% of the chest and 13% of other sites (ears, skinfolds). Patients themselves identified stress as the main triggering factor, whether for episodes in general, for the first episode or for the current episode. A stressful event was in fact found in the majority of cases. The fact that stress was recognised as a triggering factor for episodes was not associated with a higher depression score (HAD or Beck) but was associated with a higher anxiety score (STAI). The psychological effects of the disease were pronounced in 11% of patients, moderate in 20%, mild in 35%, and nil in 25%, with 9% of patients stating no opinion. Patients with facial involvement were more depressed in terms of Beck Depression Index score. Two characteristics noted at inclusion were predictive for the onset of at least one further episode or persistence of an ongoing episode four months later: patients' designation of stress as the cause of the previous episode, and STAI score. DISCUSSION: This study confirms that seborrheic dermatitis is often preceded by a stressful event and that stress tends to suggest a poor prognosis. This is the first study to show a possible link between stressful life events and episodes of seborrheic dermatitis. It suggests the need to confirm these results through a study comparing patients with seborrheic dermatitis and subjects without the disease. It also shows that depression is more common among patients with facial involvement and that anxiety is an aggravating factor.

[Clinical and therapeutic profile and quality of life of patients with seborrheic dermatitis]. / Perfil clínico, terapéutico y calidad de vida de los pacientes con dermatitis seborreica.

INTRODUCTION: The clinical characteristics of seborrheic dermatitis (SD), therapeutic strategies employed in current clinical practice and impact on the quality of life in the Spanish population are described. METHODS: An epidemiological, multicenter, transversal study in patients older than 16 years with seborrheic dermatitis. We evaluated the intensity of symptoms (scale 0-4), and impact on the quality of life by the Skindex-29 questionnaire (scale 0-100). RESULTS: Two thousand one hundred and fifty nine patients participated, the mean age was 43,6 years, 55 % were men and 42 % had a family history of seborrheic dermatitis. Diagnosis is usually carried out at a mean age of 33,7 years. The median number of outbreaks in the last year is three. The median duration of each outbreak is 14 days. The most involved areas are the face (88 %) and scalp (70 %). The mean intensities are as follows: scaling 1.9, erythema 1.89, pruritus 1.73, oily skin 1.52, and induration 0.87. Ninety-eight percent of patients report a trigger factor for outbreaks, namely stress/depression/fatigue (76 %) and seasonal variation (44 %). Acne is the most common concomitant disease (35 %). The most common treatments are topical steroids (60 %), imidazole antifungals (35 %) and hydratating/nutritive products (31 %). The mean Skindex-29 global score is 20.5. CONCLUSIONS: The most common clinical profile of seborrheic dermatitis is a 40-year-old patient with facial/scalp involvement of mild to moderate intensity with a history of stress/depression/fatigue prior to the outbreak. The most common treatments in the daily clinical practice are topical steroids and imidazole antifungals. The impact of seborrheic dermatitis in the quality of life is low.

Knowledge, attitude and practice regarding dandruff among soldiers.

OBJECTIVE: To assess the knowledge, attitude and practice regarding dandruff among soldiers. DESIGN: Cross-sectional study. PLACE AND DURATION OF STUDY: Departments of Dermatology at Combined Military Hospitals, Abbottabad, Malir and Gujranwala from January 2006 to March 2006. PATIENTS AND METHODS: Serving male soldiers posted at Abbottabad, Malir and Gujranwala Cantonments were included in the study. Convenience sampling was used to distribute the questionnaire. All soldiers included in the study were asked or assisted by the trained staff to fill the close-ended questionnaire in Urdu, which included information about demographic profile and questions relevant to the objectives of the study. The ethical requirements for the study were fulfilled. SPSS-10 was used for data management. RESULTS: A total of 800 serving male soldiers were surveyed. Five hundred and twenty-one soldiers (65.1%) answered yes to dandruff, whereas 279 (34.9%) replied in negative. Dandruff was considered a disease by 433 (83.1%) respondents. Hair fall (n=392, 75.2%) and scalp itching (n=380, 72.9%) were the common symptoms and 330 (63.3%) respondents were embarrassed by dandruff. Bad water (n=93, 17.8%), winter (n=40, 07.6%) and lack of sleep (n=30, 05.7%) were considered the most common causes of dandruff. Majority of the individuals (n=487, 93.4%) used different hair oils and household remedies for the treatment of dandruff. One hundred and fourteen (21.9%) and 50 (09.6%) participants consulted doctors and traditional healers respectively for their dandruff. Advertisements in electronic or print media and wall hoardings etc. influenced 213 (40.9%) respondents to use various anti-dandruff shampoos, hair tonics and oils. CONCLUSION: Dandruff is a common problem and there is a need for education programmes and formulation of a policy regarding the positive role of media on health matters.

Scalpdex: a quality-of-life instrument for scalp dermatitis.

OBJECTIVE: To develop a scalp dermatitis-specific quality-of-life instrument. METHODS: Based on the results of directed focus sessions with 8 patients with scalp psoriasis or seborrheic dermatitis, we conceptualized 3 major constructs that explain the way scalp dermatoses affect patient quality of life: symptoms, functioning, and emotions. We constructed a 23-item instrument, Scalpdex, and tested its reliability, responsiveness, and validity. RESULTS: Fifty-two dermatology patients completed the study. We demonstrated construct validity by confirming that the factors derived by principal axes factor analyses with orthogonal rotation correlated to our hypothesized scales (r = 0.76-0.84) and that differences in symptom, functioning, and emotion scores differed among the varying levels of self-reported scalp severity more than would be expected by chance (P<.05 by analysis of variance). The instrument demonstrated reliability with internal consistency (Cronbach alpha, 0.62-0.80) and reproducibility (intraclass correlation coefficient, 0.90-0.97). The quality-of-life scores changed in the expected direction in our test for responsiveness (P

Prevalence of mental health problems in acne patients.

BACKGROUND: Acne is the most common of all skin diseases. The condition affects young people at the time when they are undergoing maximum social and physical change and can produce significant psychological scarring. This study was done to determine the Mental Health problem in Patients suffering from acne and to determine significant difference of mental health problems in acne patients in comparison to seborrhic dermatitis patients as a control group. METHODS: 50 subjects with acne and 50 with seborrhic skin problems (13-25 yrs age) were included in this study through Psychiatry OPD of Lady Reading Hospital, Peshawar. The period of study was from March 1998 to August 1998. The patients were assessed for psychiatric problems by using WHO Guide to mental health in primary care ICD 10 chapter V primary care. The statistical significance was determined by chi square. RESULTS: The data shows that out of 50 acne patients 19 (38%) were suffering from Depression, with a female predominance. The control group (seborrhic) presented lower prevalence of Depression i.e. 57% in females. Similarly Anxiety problem in particular social anxiety were overall more in acne group (34%) as compared to seborrhea group (10%). A statistically significant difference was observed between the two groups indicating that depression and social anxiety was more in the acne group. A consistent finding in the study over six months depicted the difference between gender i.e. more females presenting with depression. Total Depressed Patients were 19, while total with suicidal Thoughts were 4 (21%). CONCLUSION: The importance of this study is to highlight depression among such patients.

[A case of pathomimia]. / Sluchai patomimii.

The authors describe a case of pathomimesis with simulation of seborrheal pemphigus, when the patient was referred to Group II invalidity.
