RESUMEN

BACKGROUND: Bexarotene is the only Food and Drug Administration-approved retinoid for the treatment of cutaneous T-cell lymphoma (CTCL) and is associated with a relatively high frequency of adverse effects. Acitretin has anecdotally been reported to be effective for CTCL. OBJECTIVE: We sought to determine the effectiveness and tolerability of acitretin as primary or adjuvant therapy for CTCL. METHODS: We conducted a retrospective chart review of patients with CTCL treated with acitretin at a single tertiary care center. RESULTS: A total of 32 patients with CTCL were included: 29 had mycosis fungoides, 2 had Sézary syndrome, and 1 had CTCL not otherwise specified. Median patient age was 55 years; 56% were male; 47% were white, 47% black, and 6% other. In all, 3% of patients were stage IA, 69% stage IB/IIA, 16% stage IIB, 6% stage III, and 6% stage IV. Six patients received acitretin alone; 26 received acitretin in addition to another CTCL therapy. The overall response rate was 59%. In all, 25% of patients had stable disease and 16% had progressive disease. Median duration of response was 28 months. Adverse effects were generally mild with 5 patients discontinuing therapy because of these. LIMITATIONS: In this small retrospective chart review, many patients were on other CTCL therapies while on acitretin; therefore precise assessment of response to acitretin alone was difficult. CONCLUSIONS: Acitretin is well tolerated and potentially effective for early-stage CTCL. Response to acitretin, either as adjuvant therapy monotherapy, is comparable with the response to oral agents currently approved for this disease.

RESUMEN

IMPORTANCE: Cancer worry about developing melanoma in at-risk patients may affect one's quality of life and adherence to screening. Little is known about melanoma-related worry in patients with atypical mole syndrome (AMS). OBJECTIVES: To quantify levels and elucidate predictors of worry related to developing melanoma in patients with AMS and to determine whether total-body digital photography (TBDP) in pigmented lesion clinics (PLCs) reduces worry. DESIGN, SETTING, AND PARTICIPANTS: In this pretest-posttest study, patients with AMS from PLCs at 2 academic medical centers were recruited from June 1, 2005, through October 31, 2008, to answer questions about cancer worry before and after undergoing TBDP. Questionnaires used included the new melanoma and recurrent melanoma Revised Impact of Event Scale (RIES), the Melanoma Worry Scale (MWS), the Hospital Anxiety and Depression Scale, and the Life Orientation Test. INTERVENTIONS: All patients underwent TBDP. MAIN OUTCOMES AND MEASURES: Changes in the MWS and new melanoma RIES scores. RESULTS: A total of 138 patients completed baseline questionnaires; 108 patients (78.3%) completed questionnaires after TBDP. Baseline levels of worry were low and reduced further after TBDP. In patients with a personal history of melanoma, worry was reduced on all scales. In patients without a personal history of melanoma, only the new melanoma RIES score was significantly decreased. Predictors of baseline MWS scores include female sex, personal history of melanoma, and higher Hospital Anxiety and Depression Scale scores, adjusted for demographics, family history of melanoma, and Life Orientation Test scores. Adjusted predictors of the baseline new melanoma RIES score were similar but also included lower educational level and did not include sex. CONCLUSIONS AND RELEVANCE: Patients with AMS have low levels of melanoma-related worry, which is similar to data from other populations at high risk of cancers. We found that TBDP is a clinically useful tool that can be used in PLCs to help decrease worry about developing melanoma in at-risk patients.

RESUMEN

The concept of quality of life (QOL) is becoming increasingly important in medicine, particularly in dermatology where many cutaneous diseases have the potential to affect the quality rather than the length of life. There is increasing interest in devising methodology to accurately measure the impact of disease on QOL for use in clinical practice, research studies, and economic analyses. The question of which dermatologic QOL instruments to choose inevitably arises. The aim of this article is to familiarize readers with health status measures and to review their use in dermatology.

RESUMEN

Within the last few decades, outcomes research, and in particular quality of life (QoL) outcomes research, has become integrated into clinical and research practices. QoL outcomes are important to dermatology, because many diseases carry significant psychosocial burdens and morbidity from appearance and symptoms with few cases of mortality. In this article, the authors discuss the future directions in QoL. Important areas are the determination, clinical significance and interpretation of measured QoL values. Additionally, the development of proxies for preference-based QoL measures and modules for health status QoL measures are discussed.

RESUMEN

Clinical meaning can be assigned to scores of health status measures by using a variety of approaches. The anchor-based approach involves determining the difference on a quality of life (QOL) scale that corresponds to a self-reported small but important change on a global scale given concomitantly, which serves as an independent anchor. This article focuses on the anchor-based banding approach and reviews methods to assign clinical meaning to QOL measures, specifically the Dermatology Life Quality Index (DLQI) and Skindex. This article also includes pilot data that compares the DLQI and Skindex using these previously validated banding systems.

RESUMEN

In this overview of preference-based measures, utilities and willingness to pay (WTP) are discussed as measures relevant to dermatology for capturing the burden of skin diseases. An overview is provided of the concepts of utilities and WTP and their importance in decision making. Specific examples of elicitation methods for capturing utility and WTP measures are provided. Prior studies exploring utilities and WTP in dermatology are reviewed. Each of these measures has limitations and likely varying relevance to specific dermatologic diseases and to specific individuals.

RESUMEN

OBJECTIVE: To compare the impact of chronic pruritus and chronic pain on quality of life (QoL) using directly elicited health utility scores. DESIGN: Cross-sectional study. SETTING: Convenience sample of patients attending the Emory Dermatology Clinic, Emory Spine Center, and Emory Center for Pain Management, Atlanta, Georgia. PARTICIPANTS: Adult men and women (aged ≥ 18 years) experiencing chronic pain or pruritus for 6 weeks or more. MAIN OUTCOME MEASURES: The mean utility score of patients with chronic pruritus was compared with that of patients with chronic pain. A regression analysis was performed to determine the impact of the primary predictor variable-symptom type-on the primary outcome variable-mean utility score (a metric representing the impact on QoL). RESULTS: The study included 73 patients with chronic pruritus and 138 patients with chronic pain. The mean (SD) utility among patients with pruritus was 0.87 (0.27) compared with 0.77 (0.31) for patients with pain (P < .01). After symptom severity, duration, and demographic factors were controlled for, only symptom severity (0.03 [P < .05]) and single marital status (-0.12 [P = .02]), but not symptom type (P = .43), remained significant predictors of the mean symptom utility score. CONCLUSIONS: Chronic pruritus has a substantial impact on QoL, one that may be comparable to that of pain. The severity of symptoms and the use of support networks are the main factors that determine the degree to which patients are affected by their symptoms. Addressing support networks in addition to developing new therapies may improve the QoL of itchy patients.

RESUMEN

Photoprotection against ultraviolet light is an important part of our armamentarium against actinically derived skin cancers. However, there has been concern that adherence to photoprotection may lead to low vitamin D status, leading to negative effects on patients' health. In this work we discuss previous findings in this area, which do not give a clear picture as to the relationship between vitamin D levels and photoprotection measures, as well as research performed by the authors, who did not detect a relationship between serum 25(OH)D levels and adherence to photoprotection measures in subjects with skin cancer, as assessed by the use of sunscreen, clothing, hats, sunglasses, and umbrellas/shade through the Sun Protection Habits Index. Subjects who took vitamin D oral supplementation had greater serum 25(OH)D levels than those who did not, whereas dietary intake through foods did not predict 25(OH)D levels in the authors' study. However, there was a high prevalence of vitamin D insufficiency and deficiency in the authors' study population, highlighting the importance of assessing vitamin D status and recommending oral vitamin D supplementation when indicated.

RESUMEN

The primary objective of our study was to update the prevalence of total body photography (TBP) utilization and the rationale for its implementation as an adjunctive screening measure by academic dermatologists across the USA, and investigate the emergence of total body digital photography (TBDP). Our secondary objective was to further examine how TBP/TBDP is being incorporated into the dermatology screening examination in academic pigmented lesion clinics. A questionnaire was mailed to 113 dermatology departments across the USA. About 43% (49/113) of surveyed departments responded. TBP was used by 67% (33/49) of the respondents. Of these respondents, 33% (11/33) used TBDP alone, 33% (11/33) used TBDP in combination with nondigitally based TBP, and 33% (11/33) used nondigital TBP with print photos. The three most frequently cited reasons for the use of full-body baseline photographs were that they reduced patient anxiety, led to fewer biopsies, and helped to find melanoma early in the curable stage. Respondents who did not use full body baseline photographs cited logistical constraints as the number one reason, followed by perceived lack of utility. In conclusion, our study shows that there is a significant number of academic dermatologists using TBP/TBDP. However, this study also shows that there are conflicting beliefs among academic dermatologists concerning the efficacy of TBP/TBDP. At this point with a documented growing trend in utilization of TBP, more studies are needed to evaluate the efficacy of this screening adjunct to diagnose melanoma early and positively impact survival because of early diagnosis.

RESUMEN

Virtual microscopy is being used in medical schools to teach histology and pathology. It is also being used in resident education, in-training examinations (dermatology), and certification examinations (pathology). There are, however, few studies comparing its diagnostic accuracy and acceptability compared with traditional glass slides. This study sought to compare residents' abilities in diagnosing dermatopathology disorders in 2 image formats (traditional microscopic slides and whole mount digitized images) and to assess their perceptions of virtual microscopy in dermatopathology. Residents in dermatology and pathology training programs at 14 institutions were given a randomized combination of 20 virtual and glass slides and were asked to identify the diagnoses from multiple foils. They were then asked to give their impressions about the virtual images. Descriptive data analysis and comparison of groups using Pearson chi(2) and Fisher exact tests for categorical variables and Student t test for continuous variables were performed. Residents in dermatology and pathology performed similarly in diagnosing dermatopathology disorders using virtual slides or glass slides (mean [SD] correct for virtual versus glass, 5.48 (1.72) versus 5.57 (2.06); P = .70). The order of administration of virtual versus glass slides did not affect the percentage of questions answered correctly. Most residents supported the use of virtual microscopy as a learning aid, whereas fewer favored its use in testing (79% versus 44%, respectively). Residents performed similarly in making dermatologic diagnoses using virtual slides compared with glass slides despite the residents' preference for the latter.

RESUMEN

OBJECTIVE: To estimate annual direct and indirect health care costs in patients with chronic idiopathic urticaria (CIU) managed with conventional therapies. DESIGN: A cost analysis consisting of a survey-guided and retrospective medical record review of direct and indirect health care costs from a societal perspective in patients with CIU. SETTING: The Johns Hopkins University allergy and dermatology ambulatory clinics. PARTICIPANTS: Fifty adults with active CIU were recruited in sequential order. Individuals who were taking corticosteroids or other immunosuppressants in the month before enrollment were excluded from the study. MAIN OUTCOME MEASURES: We estimated direct health care costs, which included laboratory, medication, outpatient visit, and emergency department and hospital visit costs. We also estimated indirect costs, which included earnings lost owing to travel to outpatient visits and absences from work owing to CIU-related illness. RESULTS: Patients with CIU consumed a mean (SD) of $2047 ($1483) annually. Because CIU is primarily an outpatient disease, medication costs alone accounted for 62.5% ($1280) of the total annual cost. Indirect costs accounted for 15.7% ($322) of the total costs. CONCLUSIONS: High medication costs, followed by total indirect costs, result in the largest economic burden among patients with CIU. High medication costs may place low-income patients at risk for suboptimal treatment and increased burden due to poorly controlled disease. Our estimated total health care costs for CIU are comparable to those of other skin diseases such as vitiligo and bullous disease.
