Comparative Study of Efficacy Between Cyclosporine and Alitretinoin in Patients With Chronic Hand Eczema.

Background: Systemic remedies such as cyclosporine, methotrexate, and retinoids are off-license treatment options that are considered for severe chronic hand eczema (CHE) that is resistant to first-line treatment. Objectives: The objective of this study was to determine the optimal treatment of CHE patients, including those with atopic dermatitis, and to compare the efficacy between cyclosporine and alitretinoin. Methods: This study was retrospective and included CHE patients who visited the Department of Dermatology at Hanyang University Seoul Hospital in Korea between March 2013 and February 2020. Results: A total of 95 CHE patients was included in this study. In the cyclosporine treatment group, there were more patients with severe baseline Investigator Global Assessment (IGA) (P = 0.033) and higher immunoglobulin E (IgE) level (P = 0.019). The mean recurrence duration was 15.9 weeks in the alitretinoin group and 22.9 weeks in the cyclosporine group, the difference between which was not statistically significant. In a subgroup analysis according to treatment drug, only the low IgE group showed a better recurrence profile for alitretinoin treatment compared to cyclosporine treatment (P = 0.039). When comparing the cumulative recurrence rate during the treatment period and subsequent follow-up periods, the cyclosporine group showed a greater incidence of recurrence than the alitretinoin group in all follow-up periods. The results of our study are consistent with the previously reported efficacy of alitretinoin. Despite the rapid response in the cyclosporine group, 12 weeks of CHE treatment with alitretinoin showed superior efficacy compared to cyclosporine treatment. Conclusions: Both alitretinoin and cyclosporine groups showed efficacy in patients with CHE. Cyclosporine is an alternative treatment of CHE that is refractory to alitretinoin or relapses after its use, especially in the presence of atopic dermatitis.

Self-inflating oral tissue expander for ridge augmentation in the severely atrophic mandible.

In dentistry, tissue expanders have been used to obtain sufficient soft tissue for alveolar bone augmentation in the severely atrophic ridge. Herein, we review two cases of soft tissue augmentation using a self-inflating tissue expander in patients in the Department of Oral and Maxillofacial Surgery at Ewha Womans University Mokdong Hospital for bone graft and implant operations. The results of each patient were presented using pre-operative and post-operative radiographs and clinical exams. The results of our study indicate successful bone graft and implant surgery using a self-inflating tissue expander.
