Quality of Life in a Vitiligo Support Group.

BACKGROUND: No study has examined the impact of vitiligo support group membership on vitiligo patient quality of life (QoL).

OBJECTIVE: We sought to examine the QoL impact of vitiligo support groups by comparing QoL and associated patient characteristics between vitiligo patients who are and are not members of a vitiligo support group.

METHODS: Members of a Henry Ford Hospital-sponsored, Southeast Michigan Vitiligo Support Group were compared to non-member vitiligo patients recruited from a previous study cohort.17 Eligible patients were asked to complete the Dermatology Life Quality Index (DLQI) and a study-specific questionnaire designed to collect relevant patient characteristics.

RESULTS: The mean DLQI scores for the support group members and non-members were similar (7.1 ± 5.4 and 6.0 ± 6.5, respectively; P-value 0.2), despite the support group members reporting more severe overall disease and increased disease severity in exposed portions of the body. The African-American: Caucasian ratio and the prevalence of unemployment were both significantly higher among the support group participants. LIMITATIONS: Small sample size may have limited the study's ability to demonstrate the differences between the support group participants and the controls.

CONCLUSIONS: The similar QoL despite an increased prevalence of poorer QoL indicators among the support group participants suggests a protective effect of support group membership.

Providers' Experiences with a Melanoma Web-Based Course: a Discussion on Barriers and Intentions.

Primary care visits provide an opportunity for skin examinations with the potential to reduce melanoma mortality. The INFORMED (INternet curriculum FOR Melanoma Early Detection) Group developed a Web-based curriculum to improve primary care providers' (PCPs') skin cancer detection skills. This study details feedback obtained from participant focus groups, including the feasibility of implementing in other PCP practices. Practicing PCPs at Henry Ford Health System and Kaiser Permanente Northern California completed the curriculum. Feedback sessions were conducted with standardized questions focusing on four domains: (1) overall impressions of the curriculum, (2) recommendations for improvement, (3) current skin examination practices, and (4) suggestions for increasing skin screening by PCPs. Discussions at each site were audio recorded, transcribed verbatim, and de-identified. Providers (N = 54) had a positive impression of the Web-based curriculum, with suggestions to provide offline teaching aids and request assistance. Despite having improved confidence in diagnosing malignant lesions, many providers felt a lack of confidence in performing the screening and time constraints affected their current practices, as did institutional constraints. Providers intended to increase discussion with patients about skin cancer. The accessibility, effectiveness, and popularity of the curriculum indicate potential for implementation in the primary care setting. Participating providers noted that institutional barriers remain which must be addressed for successful dissemination and implementation.

Identification of Stevens-Johnson syndrome and toxic epidermal necrolysis in electronic health record databases.

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) carry a high mortality risk. While identifying clinical and genetic risk factors for these conditions has been hindered by their rarity, large electronic health databases hold promise for identifying large numbers of cases for study, especially with the introduction in 2008 of ICD-9 codes more specific for these conditions. OBJECTIVE: The objective of this study is to estimate the validity of ICD-9 codes for ascertaining SJS/TEN in 12 collaborating research units in the USA, covering almost 60 million lives. METHODS: From the electronic databases at each site, we ascertained potential cases of SJS/TEN using ICD-9 codes. At five sites, a subset of medical records was abstracted and standardized criteria applied by board-certified dermatologists to adjudicate diagnoses. Multivariate logistic regression was used to identify factors independently associated with validated SJS/TEN cases. RESULTS: A total of 56 591 potential cases of SJS/TEN were identified. A subset of 276 charts was selected for adjudication and 39 (of the 276) were confirmed as SJS/TEN. Patients with the ICD-9 codes introduced after 2008 were more likely to be confirmed as cases (OR 3.32; 95%CI 0.82, 13.47) than those identified in earlier years. Likelihood of case status increased with length of hospitalization. Applying the probability of case status to the 56 591 potential cases, we estimated 475-875 to be valid SJS/TEN cases. CONCLUSION: Newer ICD-9 codes, along with length of hospitalization, identified patients with a high likelihood of SJS/TEN. This is important for identification of subjects for future pharmacogenomics studies.

Perception of xeroderma pigmentosum support group members of xeroderma pigmentosum lifestyle impact.

Xeroderma pigmentosum (XP) is a genetic condition, which can cause an extreme sensitivity to sunlight and an increased risk of skin cancer due to errors in DNA repair. An online survey was administered to a convenience sample of participants who were members of an online support group for XP patients and their families to determine common symptoms and quality of life. The Dermatologic Life Quality Index (DLQI) or the Children's Dermatologic Life Quality Index (CDLQI) was used depending on patient age. A total of four patients and two parents of young patients completed our survey. Quality of life as measured through the DLQI and CDLQI was moderately affected.

Photoprotection counseling of non-white ethno-racial groups: a survey of the practice of expert dermatologists.

The morbidity of skin cancer in non-white, ethno-racial populations is well established, yet no specific guidelines exist addressing the manner in which this population should be counseled on photoexposure. We conducted a 20-item survey to assess the behavior of specialized dermatologists when providing photoprotection recommendations to non-white, ethno-racial patients as well as the perceived relevance of counseling for this group. Our study demonstrated that key opinion leaders within the fields of photodermatology and ethnic dermatology believe that photoprotection counseling is beneficial for ethno-racial minorities. Based on these preliminary data and other recently published reports, the development of photoprotection guidelines specific to non-white, ethno-racial groups may be warranted.

Skin-of-color epidemiology: a report of the most common skin conditions by race.

To quantify and compare diagnoses according to race in pediatric Health Maintenance Organization (HMO) health plan patients seen in a general dermatology clinic over a 10-year period. Retrospective cohort of health plan pediatric patients seen in the dermatology clinic between 1997 and 2007 was established using an electronic medical record database. Diagnoses and diagnostic codes were recorded according to International Classification of Diseases, Ninth Revision (ICD-9) diagnostic codes grouped on their first three digits. The proportion of patients with each diagnosis was determined according to race and sex, and the 10 most common diagnoses were determined. The most common diagnoses observed in all pediatric patients were acne (28.6%), dermatitis (19.4%), and warts (16.2%), accounting for more than 60% of dermatologic visits by children. Although acne (29.9%), warts (22.6%), and dermatitis (13.1%) were also the most common diagnoses for Caucasian children, African American pediatric patients were most commonly seen for dermatitis (29.0%), acne (27.5%), and dermatophytosis (10.2%). The three most common diagnoses for Asian patients were dermatitis (29.1%), acne (22.2%), and warts (12.6%). Acne remains one of the most common dermatologic diagnoses in children of all races. Differences in frequency of office visits for dermatitis, warts, and dermatophytosis were seen when comparing children of other races with Caucasian children.

Developing an interactive web-based learning program on skin cancer: the learning experiences of clinical educators.

Web-based learning in medical education is rapidly growing. However, there are few firsthand accounts on the rationale for and development of web-based learning programs. We present the experience of clinical educators who developed an interactive online skin cancer detection and management course in a time-efficient and cost-efficient manner without any prior skills in computer programming or technical construction of web-based learning programs. We review the current state of web-based learning including its general advantages and disadvantages as well as its specific utility in dermatology. We then detail our experience in developing an interactive online skin cancer curriculum for primary care clinicians. Finally, we describe the main challenges faced and lessons learned during the process. This report may serve medical educators who possess minimal computer programming and web design skills but want to employ the many strengths of web-based learning without the huge costs associated with hiring a professional development team.

Bendamustine-induced "flagellate dermatitis".

BACKGROUND: The term "flagellate erythema" after bleomycin therapy was described as bleomycin-induced linear hyperpigmentation. Since then, this pattern has not been related to any other chemotherapeutic regimen. OBSERVATION: We report a rare patient with chronic lymphocytic leukemia who developed "flagellate dermatitis" induced by bendamustine. CONCLUSION: Chemotherapy induced "Flagellate Dermatitis" is a rare finding reported only after bleomycin therapy. We describe the first case with this characteristic eruption pattern after administration of bendamustine.

Skin cancer education for primary care physicians: a systematic review of published evaluated interventions.

BACKGROUND: Early detection of melanoma may provide an opportunity to positively impact melanoma mortality. Numerous skin cancer educational interventions have been developed for primary care physicians (PCPs) to improve diagnostic accuracy. Standardized training is also a prerequisite for formal testing of melanoma screening in the primary care setting. OBJECTIVE: We conducted a systematic review to determine the extent of evaluated interventions designed to educate PCPs about skin cancer, including melanoma. DESIGN: Relevant studies in the English language were identified through systemic searches performed in MEDLINE, EMBASE, BIOSIS, and Cochrane through December 2010. Supplementary information was obtained from corresponding authors of the included studies when necessary. APPROACH: Studies eligible for inclusion formally evaluated skin cancer education interventions and were designed primarily for PCPs. Excluded studies lacked a specified training intervention, used decision-making software, focused solely on risk factor identification, or did not directly educate or assess participants. Twenty studies met the selection criteria. Data were extracted according to intervention content and delivery format, and study outcomes. KEY RESULTS: All interventions included instructions about skin cancer diagnosis, but otherwise varied in content. Curricula utilized six distinct educational techniques, usually incorporating more than one. Intervention duration varied from 12 min to over 6 h. Eight of the 20 studies were randomized trials. Most studies (18/20, 90%) found a significant improvement in at least one of the following five outcome categories: knowledge, competence, confidence, diagnostic performance, or systems outcomes. Competence was most commonly measured; no study evaluated all categories. Variability in study design, interventions, and outcome measures prevented correlation of outcomes with intervention characteristics. CONCLUSIONS: Despite the development of many isolated educational interventions, few have been tested rigorously or evaluated under sufficient standardized conditions to allow for quantitative comparison. Improved and rigorously tested skin cancer educational interventions for PCPs with outcome measures focusing on changes in performance are needed.

Racial and ethnic variations in incidence and survival of cutaneous melanoma in the United States, 1999-2006.

BACKGROUND: Most melanoma studies use data from the National Cancer Institute Surveillance, Epidemiology, and End Results Program or individual cancer registries. Small numbers of melanoma cases have limited in-depth analyses for all racial and ethnic groups. OBJECTIVE: We sought to describe racial and ethnic variations in melanoma incidence and survival. METHODS: Incidence for invasive melanoma and 5-year melanoma-specific survival were calculated for whites, blacks, American Indians/Alaskan Natives, Asians/Pacific Islanders (API), and Hispanics using data from 38 population-based cancer registries. RESULTS: Incidence rates of melanoma were significantly higher for females than males among whites and Hispanics under 50 years of age and APIs under 40 years of age. White and black patients were older (median age: 59-63 years) compared with Hispanics, American Indians/Alaskan Natives, and API (median age: 52-56 years). The most common histologic type was acral lentiginous melanoma among blacks and superficial spreading melanoma among all other racial and ethnic groups. Hispanics had the highest incidence rate of acral lentiginous melanoma, significantly higher than whites and API. Nonwhites were more likely to have advanced and thicker melanomas at diagnosis and lower melanoma-specific survival compared with whites. LIMITATIONS: Over 50% of melanoma cases did not have specified histology. The numbers of nonwhite patients were still relatively small despite broad population coverage (67% of United States). CONCLUSIONS: Racial and ethnic differences in age at melanoma diagnosis, anatomic sites, and histologic types suggest variations in etiologic pathways. The high percentages of advanced and thicker melanomas among nonwhites highlight the need to improve melanoma awareness for all race and ethnicity in the United States.

Association between cutaneous melanoma incidence rates among white US residents and county-level estimates of solar ultraviolet exposure.

BACKGROUND: Recent US studies have raised questions as to whether geographic differences in cutaneous melanoma incidence rates are associated with differences in solar ultraviolet (UV) exposure. OBJECTIVES: We sought to assess the association of solar UV exposure with melanoma incidence rates among US non-Hispanic whites. METHODS: We assessed the association between county-level estimates of average annual solar UV exposure for 1961 to 1990 and county-level melanoma incidence rates during 2004 to 2006. We used Poisson multilevel mixed models to calculate incidence density ratios by cancer stage at diagnosis while controlling for individuals' age and sex and for county-level estimates of solar UV exposure, socioeconomic status, and physician density. RESULTS: Age-adjusted rates of early- and late-stage melanoma were both significantly higher in high solar UV counties than in low solar UV counties. Rates of late-stage melanoma incidence were generally higher among men, but younger women had a higher rate of early-stage melanoma than their male counterparts. Adjusted rates of early-stage melanoma were significantly higher in high solar UV exposure counties among men aged 35 years or older and women aged 65 years or older. LIMITATIONS: The relationship between individual-level UV exposure and risk for melanoma was not evaluated. CONCLUSIONS: County-level solar UV exposure was associated with the incidence of early-stage melanoma among older US adults but not among younger US adults. Additional studies are needed to determine whether exposure to artificial sources of UV exposure or other factors might be mitigating the relationship between solar UV exposure and risk for melanoma.

Identification of patients with nonmelanoma skin cancer using health maintenance organization claims data.

Cancer registries usually exclude nonmelanoma skin cancers (NMSC), despite the large population affected. Health maintenance organization (HMO) and health system administrative databases could be used as sampling frames for ascertaining NMSC. NMSC patients diagnosed between January 1, 1988, and December 31, 2007, from such defined US populations were identified by using 3 algorithms: NMSC International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, NMSC treatment Current Procedural Terminology (CPT) codes, or both codes. A subset of charts was reviewed to verify NMSC diagnosis, including all records from HMO-enrollee members in 2007. Positive predictive values for NMSC ascertainment were calculated. Analyses of data from 1988-2007 ascertained 11,742 NMSC patients. A random sample of 965 cases was selected for chart review, and NMSCs were validated in 47.0% of ICD-9-CM-identified patients, 73.4% of CPT-identified patients, and 94.9% identified with both codes. All charts from HMO-health plan enrollees in 2007 were reviewed (n = 1,116). Cases of NMSC were confirmed in 96.5% of ICD-9-CM-identified patients, 98.3% of CPT-identified patients, and 98.7% identified with both codes. HMO administrative data can be used to ascertain NMSC with high positive predictive values with either ICD-9-CM or CPT code, but both codes may be necessary among non-HMO patient populations.

Tanning beds, skin cancer, and vitamin D: An examination of the scientific evidence and public health implications.

Indoor tanning has become increasingly popular over the past decades, despite evidence of an increased risk of melanoma and, possibly, nonmelanoma skin cancer. Tanning bed proponents cite the health benefits of vitamin D to support indoor tanning, including concerns that reduced vitamin D levels or certain vitamin D receptor polymorphisms may be associated with increased incidence of various cancers, including cutaneous melanoma. However, most tanning devices primarily emit ultraviolet A, which is relatively ineffective in stimulating vitamin D synthesis. Health benefits can be fully dissociated from the ultraviolet exposure risks with vitamin D supplementation, although optimal levels remain to be established. Indoor tanning represents an avoidable risk factor for skin cancer, and education of the general public as well as the enactment and stricter enforcement of indoor tanning legislation are a public health imperative.

The association of physician-specialty density and melanoma prognosis in the United States, 1988 to 1993.

BACKGROUND: Studies suggest physician workforce may influence cancer outcomes. OBJECTIVE: We sought to quantify the effect of physician-specialty density on melanoma prognosis. METHODS: Data from 17,702 melanoma cases reported to the Surveillance, Epidemiology, and End Results program from 1988 to 1993 were merged with sociodemographic data (1990 US Census) and dermatologist, family practitioner, and internist density data (Area Resource File). Linear and logistic regression analyses were used to model prognosis (melanoma mortality to incidence ratio). RESULTS: A higher density of dermatologists was associated with better prognosis (lower mortality to incidence ratio) (beta = -50 x 10(-4); SE 8 x 10(-4)). Internist density was also a significant predictor of better prognosis whereas increased family practitioner density was associated with worse prognosis. Controlling for sociodemographics, physician density remained a significant predictor of the mortality to incidence ratio. LIMITATIONS: Socioeconomic factors were estimated. Physician density was examined by county. CONCLUSION: Controlling for sociodemographic factors, physician-specialty density predicted melanoma prognosis. This suggests that specialist health care availability may affect melanoma outcomes.

Incidence of nonmelanoma skin cancer in a cohort of patients with vitiligo.

BACKGROUND: Nonmelanoma skin cancer (NMSC) incidence in patients with vitiligo has not been studied. OBJECTIVE: We sought to quantify the incidence of NMSC in patients with vitiligo. METHODS: A cohort of 477 patients with vitiligo and no history of NMSC seen in an outpatient academic center between January 2001 and December 2006 was established. All charts for patients with vitiligo were reviewed for incident NMSC, and histopathology verified. Age-adjusted (2000 US Standard Million) incidence rates were calculated and compared to US rates. RESULTS: Six patients with NMSC were identified; all were Caucasian (>61 years). Age-adjusted incidence rates were: basal cell carcinoma, male 1382/100,000; basal cell carcinoma, female 0; squamous cell carcinoma, male 465/100,000; squamous cell carcinoma, female 156/100,000. Except for basal cell carcinoma in females, all rates were higher than US rates but not statistically significant. LIMITATIONS: Comparison incidence rates from the general patient population during the same time period were unavailable. CONCLUSION: Health care providers should be aware of the possible risk of NMSC in Caucasian patients with vitiligo.

Quality of life assessment and disease experience of patient members of a web-based hydroa vacciniforme support group.

BACKGROUND/PURPOSE: Hydroa vacciniforme (HV) is a rare photodermatosis that primarily affects children. It is characterized by photodistributed vesicles that heal with scarring. The purposes of this study are to perform the initial investigation into the effect of HV on quality of life (QoL) and gain insight into disease diagnosis and management. METHODS: Using the listserv from a web-based, international HV support group, either the Dermatology Life Quality Index (DLQI) or the Children's DLQI (CDLQI), and an HV-specific questionnaire were administered. RESULTS: Fifteen HV patients participated, nine (60%) males and six (40%) females. Median age at onset was 7 years, and 11/15 (73%) were younger than 18 years. The majority of patients were Caucasian (73%). Children cited life quality as being negatively impacted by an inability to play outdoors while adults noted QoL influences due to limitations on clothing choices. The mean CLDLQI and DLQI scores, 12.1 and 8.5, respectively, suggest a higher negative QoL impact than previously reported indices for generalized eczema, atopic dermatitis, and psoriasis. CONCLUSION: When compared with other dermatoses, HV appears to have an equal or greater impact on patients' QoL. Dermatologists should be aware of the psychosociologic impact of this disease, especially on young HV patients.

Demographic and socioeconomic predictors of melanoma prognosis in the United States.

Studies suggest sociodemographic factors may influence melanoma prognosis. Our objective was to quantify sociodemographic predictors of U.S. melanoma. Data from 17,702 melanoma cases reported to the Surveillance Epidemiology and End Results (SEER) program from 1988-1993 were merged with sociodemographic data (1990 U.S. Census). Regression analysis was used to model prognosis: melanoma mortality to incidence ratio. Prognosis was significantly associated with neighborhood racial heterogeneity, education and income. Melanoma patients who resided in areas with higher education (OR 0.4, 95% CI 0.3-0.5), more White residents (OR 0.7, 95% CI 0.5-0.8), or higher incomes (OR 0.4, 95% CI 0.2-0.5) were less likely to have poor prognosis. Education explained 3.3 times more variance than race and 1.9 times more than income. Sociodemographic factors were associated with stage and tumor thickness. Neighborhood sociodemographic variables were predictive of melanoma prognosis, and suggest an important direction for targeting public health efforts to reach those in at-risk communities.

Photodynamic therapy for actinic keratoses: survey of patient perceptions of treatment satisfaction and outcomes.

BACKGROUND: While there are many available treatments for actinic keratoses (AKs), patient-preferred treatment options remain undefined. OBJECTIVE: To quantify patient perceptions and preferences in the management of AKs, including comparison of photodynamic therapy (PDT) with other therapies. METHODS: A self-administered questionnaire was mailed to 45 patients who had received PDT for AKs in 2005-2006 in the Henry Ford Health System. A series of indicators for each treatment were surveyed, including: recovery time, cosmetic appearance, patient cost, effectiveness, patient satisfaction, treatment option preference, and perceived burden of treatment. RESULTS: A total of 39 of the 45 patients participated (86.7%). A patient's reported recovery time was significantly more likely to be 1 week or less for PDT when compared with cryotherapy (p = 0.02) and surgical excision (p = 0.02). Borderline significance was found for the improved cosmetic outcome in PDT vs. surgical excision (p = 0.058) and for patient satisfaction with PDT compared with 5-fluorouracil (p = 0.058). Patients significantly preferred PDT to 5-fluorouracil (p<0.001) or imiquimod (p = 0.031). CONCLUSION: While the effectiveness of lesion clearance with PDT for AKs has been well proven in the literature, this is the first study to evaluate patient perception of the effectiveness, side-effect profile and benefits of PDT relative to several standard treatment approaches for AKs. PDT was found to have equivalent or improved recovery times, cosmetic outcomes, patient satisfaction and preference as a treatment for AKs by patients compared with other options.
