Hand eczema.

ABSTRACT: Hand eczema is often a chronic, multifactorial disease. It is usually related to occupational or routine household activities. Exact etiology of the disease is difficult to determine. It may become severe enough and disabling to many of patients in course of time. An estimated 2-10% of population is likely to develop hand eczema at some point of time during life. It appears to be the most common occupational skin disease, comprising 9-35% of all occupational diseases and up to 80% or more of all occupational contact dermatitis. So, it becomes important to find the exact etiology and classification of the disease and to use the appropriate preventive and treatment measures. Despite its importance in the dermatological practice, very few Indian studies have been done till date to investigate the epidemiological trends, etiology, and treatment options for hand eczema. In this review, we tried to find the etiology, epidemiology, and available treatment modalities for chronic hand eczema patients.

Project description:BACKGROUND:The Hand Eczema Severity Index (HECSI) is used to measure the severity of hand eczema. It is unclear what HECSI scores mean and what is the minimally important change (MIC). Furthermore, its responsiveness has not been studied. OBJECTIVES:To study the responsiveness and interpretability of the HECSI. METHODS:This was a prospective study covering two time points: baseline and after 4-12 weeks. Responsiveness was assessed using a criterion approach, with at least one-step improvement on the 'Photographic guide for severity of hand eczema' as the anchor for important improvement. Interpretability of single scores was determined by defining severity bands based on agreement with the anchor. For change scores, the smallest detectable change (SDC) was calculated in patients indicating no change and the MIC was obtained in patients indicating that they had changed using three methods: mean cutoff, receiver operating characteristic (ROC) curve and 95% limit. RESULTS:In total, 294 patients participated (160 male, mean age 44·9 years). HECSI scores improved or deteriorated in parallel with the anchor. The area under the ROC curve was 0·86 (95% confidence interval 0·81-0·91). The final severity band for single scores had a ?-coefficient of agreement of 0·694: clear, 0; almost clear, 1-16; moderate, 17-37; severe, 38-116; very severe, ? 117. The SDC in 93 unchanged patients was 40·3 points. The obtained MIC values were all smaller than the SDC. CONCLUSIONS:The HECSI has good responsiveness. This study gives meaning to HECSI scores, which can be applied to clinical decision making and the design of clinical trials. We recommend that an improvement of 41 points on the HECSI is regarded as the minimally measurable true change. What's already known about this topic? The Hand Eczema Severity Index (HECSI) is one of the most widely used measurement instruments to measure the severity of hand eczema. The HECSI has good reliability, but its responsiveness and interpretability have not been studied. What does this study add? This study shows good responsiveness of the HECSI. A severity grading for single scores is proposed. The smallest detectable change and minimally important change for improvement are determined. What are the clinical implications of this work? The obtained values help to interpret HECSI scores in daily practice and clinical studies, and may facilitate researchers in the calculation of sample sizes for clinical trials.
