ABSTRACT
Cutaneous lupus erythematosus (CLE) is an inflammatory, autoimmune disease encompassing a broad spectrum of subtypes including acute, subacute, chronic and intermittent CLE. Among these, chronic CLE can be further classified into several subclasses of lupus erythematosus (LE) such as discoid LE, verrucous LE, LE profundus, chilblain LE and Blaschko linear LE. To provide all dermatologists and rheumatologists with a practical guideline for the diagnosis, treatment and long-term management of CLE, this evidence- and consensus-based guideline was developed following the checklist established by the international Reporting Items for Practice Guidelines in Healthcare (RIGHT) Working Group and was registered at the International Practice Guideline Registry Platform. With the joint efforts of the Asian Dermatological Association (ADA), the Asian Academy of Dermatology and Venereology (AADV) and the Lupus Erythematosus Research Center of Chinese Society of Dermatology (CSD), a total of 25 dermatologists, 7 rheumatologists, one research scientist on lupus and 2 methodologists, from 16 countries/regions in Asia, America and Europe, participated in the development of this guideline. All recommendations were agreed on by at least 80% of the 32 voting physicians. As a consensus, diagnosis of CLE is mainly based on the evaluation of clinical and histopathological manifestations, with an exclusion of SLE by assessment of systemic involvement. For localized CLE lesions, topical corticosteroids and topical calcineurin inhibitors are first-line treatment. For widespread or severe CLE lesions and (or) cases resistant to topical treatment, systemic treatment including antimalarials and (or) short-term corticosteroids can be added. Notably, antimalarials are the first-line systemic treatment for all types of CLE, and can also be used in pregnant patients and pediatric patients. Second-line choices include thalidomide, retinoids, dapsone and MTX, whereas MMF is third-line treatment. Finally, pulsed-dye laser or surgery can be added as fourth-line treatment for localized, refractory lesions of CCLE in cosmetically unacceptable areas, whereas belimumab may be used as fourth-line treatment for widespread CLE lesions in patients with active SLE, or recurrence of ACLE during tapering of corticosteroids. As for management of the disease, patient education and a long-term follow-up are necessary. Disease activity, damage of skin and other organs, quality of life, comorbidities and possible adverse events are suggested to be assessed in every follow-up visit, when appropriate.

AIM: To evaluate the effectiveness and safety of micro-needling therapy in atrophic acne scar treatment. METHOD: A prospective, single centred study was implemented in a total of 31 patients suffering from atrophic acne scar grade 2 to 4 of Goodman and Baron scaring grading system was recruited. They were treated by microneedle derma roller every week in 3 months. The scars were evaluated by a magic system camera and by dermatologists clinically using Goodman and Baron scaring grading system, and Lipper and Perez score at baseline, at final treatment, 1 month and 2 months after the final treatment. RESULTS: The results showed improvement in all patients. The mean of Goodman and Barron's grade was decreased from 3.29 ± 0.59 at baseline, 2.23 ± 0.56 at final treatment, 1.93 ± 0.58 one month after the completion of therapy and to 1.77 ± 0.57 two months after the completion of therapy (with the p-value < 0.05). Similarly, Lipper and Perez score also dropped significantly from 36.48 ± 12.07 at baseline to 23.16 ± 15.01 at final treatment, to 17.83 ± 7.00 one month after the final treatment and to 16.37 ± 7.29 at two months after the final treatment (p-value < 0.05). Skin roughness and hyperpigmented spots got improved significantly. History of having nodular-cystic or vulgaris acne did not affect the effectiveness of the therapy. Side effects of the therapy were burning sensation, erythema but they were very mild and recovered in 1-2 days. No severe complication and post-inflammatory hyperpigmentation were noted. 83.3% of the patients satisfied after the completion of the therapy. CONCLUSION: Skin needling is an effective and safe method for the treatment of atrophic acne scars.
ABSTRACT
BACKGROUND: Atopic dermatitis (AD) is a common skin condition among Asians. Recent studies have shown that Asian AD has a unique clinical and immunologic phenotype compared with European/American AD. OBJECTIVE: The Asian Academy of Dermatology and Venereology Expert Panel on Atopic Dermatitis developed this reference guide to provide a holistic and evidence-based approach in managing AD among Asians. METHODS: Electronic searches were performed to retrieve relevant systematic reviews and guidelines on AD. Recommendations were appraised for level of evidence and strength of recommendation based on the U.K. National Institute for Health and Care Excellence and Scottish Intercollegiate Guidelines Network guidelines. These practice points were based on the consensus recommendations discussed during the Asia Pacific Meeting of Experts in Dermatology held in Bali, Indonesia in October 2016 and April 2017. RESULTS: The Expert Panel recommends an approach to treatment based on disease severity. The use of moisturizers is recommended across all levels of AD severity, while topical steroids are recommended only for flares not controlled by conventional skin care and moisturizers. Causes of waning efficacy must be explored before using topical corticosteroids of higher potency. Topical calcineurin inhibitors are recommended for patients who have become recalcitrant to steroid, in chronic uninterrupted use, and when there is steroid atrophy, or when there is a need to treat sensitive areas and pediatric patients. Systemic steroids have a limited role in AD treatment and should be avoided if possible. Educational programs that allow a patient-centered approach in AD management are recommended as an adjunct to conventional therapies. Recommendations on the use of phototherapy, systemic drugs, and emerging treatments are also included. CONCLUSION: The management of AD among Asians requires a holistic approach, integrating evidence-based treatments while considering accessibility and cultural acceptability.
ABSTRACT
Because Mycobacterium leprae cannot be cultivated in vitro, laboratory diagnosis of leprosy is generally made by microscopic and histopathological examination. The objective of the present study was to evaluate the sensitivity and utility of polymerase chain reaction (PCR) to detect M. leprae in comparison with other conventional methods for diagnosis such as split skin smears, histopathology and serodiagnosis. PCR amplification of the M. leprae-specific 16S ribosomal RNA was compared to other methods. Samples included 37 multibacillary (MB) patients with a positive bacteriological index (BI), 32 newly diagnosed paucibacillary (PB) patients whose BI were negative and 30 plaque psoriasis patients not residing in leprosy endemic areas as controls. The sensitivity of PCR was 30 fg of M. leprae DNA, which is equivalent to the DNA from 8.3 bacilli. The detection rate in MB and PB were 100% and 50%, respectively; the specificity was 100%. Semiquantitative evaluation of PCR correlated well with BI, but not with the morphological index (MI) nor with the serum antibody against phenolic glycolipid-1 (PGL-1). PCR detection of M. leprae targeting 16S ribosomal RNA was specific and more sensitive than conventional methods, and can contribute to early and accurate diagnosis of leprosy.
