The wound/burn guidelines - 6: Guidelines for the management of burns.

Burns are a common type of skin injury encountered at all levels of medical facilities from private clinics to core hospitals. Minor burns heal by topical treatment alone, but moderate to severe burns require systemic management, and skin grafting is often necessary also for topical treatment. Inappropriate initial treatment or delay of initial treatment may exert adverse effects on the subsequent treatment and course. Therefore, accurate evaluation of the severity and initiation of appropriate treatment are necessary. The Guidelines for the Management of Burn Injuries were issued in March 2009 from the Japanese Society for Burn Injuries as guidelines concerning burns, but they were focused on the treatment for extensive and severe burns in the acute period. Therefore, we prepared guidelines intended to support the appropriate diagnosis and initial treatment for patients with burns that are commonly encountered including minor as well as moderate and severe cases. Because of this intention of the present guidelines, there is no recommendation of individual surgical procedures.

The wound/burn guidelines – 4: Guidelines for the management of skin ulcers associated with connective tissue disease/vasculitis

The Japanese Dermatological Association prepared guidelines focused on the treatment of skin ulcers associated with connective tissue disease/vasculitis practical in clinical settings of dermatological care. Skin ulcers associated with connective tissue diseases or vasculitis occur on the background of a wide variety of diseases including, typically, systemic sclerosis but also systemic lupus erythematosus (SLE), dermatomyositis, rheumatoid arthritis (RA), various vasculitides and antiphospholipid antibody syndrome (APS). Therefore, in preparing the present guidelines, we considered diagnostic/therapeutic approaches appropriate for each of these disorders to be necessary and developed algorithms and clinical questions for systemic sclerosis, SLE, dermatomyositis, RA, vasculitis and APS.

Central nervous system effects of the second-generation antihistamines marketed in Japan--review of inter-drug differences using the proportional impairment ratio (PIR)-.

Background Second-generation antihistamines (AHs) have, in general, fewer sedative effects than the first-generation. However, important inter-drug differences remain in the degree of cognitive and/or psychomotor impairment. The extent to which a particular compound causes disruption can be conveniently compared, to all other AHs, using the Proportional Impairment Ratio (PIR). Although the PIR can differentiate the relative impairment caused by individual drugs, there is no indication of the reliability of the ratios obtained. Objective To calculate the PIRs –together with 95% confidence intervals (CIs), as an index of reliability– and compare AHs currently, or soon to be, available in Japan, with respect to their intrinsic capacity to cause impairment. Methods Results from studies of cetirizine, desloratadine, ebastine, fexofenadine, levocetirizine, loratadine, mequitazine, and olopatadine were included in the PIR calculations. All data utilised came from crossover studies in healthy volunteers which were randomised and placebo and positive-internal controlled. Existing databases from studies reporting the sedative effects of AHs on objective (speed, accuracy, memory) and subjective (feeling) psychometrics were augmented, via results from suitable studies published after the previous reviews. The null value for a PIR was one. Results A total of 45 studies were finally included for this review. Of the AHs assessed, fexofenadine, ebastine, and levocetirizine showed a PIR for objective tests of 0. However, only fexofenadine (PIR = 0.49) had an upper limit of the 95% CI of less than 1. Fexofenadine, levocetirizine, desloratadine, olopatadine, loratadine, and mequitazine all had a PIR for subjective ratings of 0, but the upper limits of the 95% CIs were all in excess of 1, although fexofenadine (PIR = 2.57) was the lowest. Conclusions The results show that there are differences between second-generation AHs in the extent of sedation produced. However, subjective ratings indicate that patients may not necessarily be aware of this.

The wound/burn guidelines – 3: Guidelines for the diagnosis and treatment for diabetic ulcer/gangrene

We aimed to prepare guidelines for the management of diabetic ulcer/gangrene with emphasis on the diagnosis and treatment of skin symptoms. They serve as a tool to improve the quality of the diagnosis and treatment in each patient and, further, to improve the level of the care for diabetic ulcer in Japan by systematically presenting evidence‐based recommendations for clinical judgments by incorporating various viewpoints.

The wound/burn guidelines - 2: Guidelines for the diagnosis and treatment for pressure ulcers.

The Wound/Burn Guidelines Committee consists of members commissioned by the Board of Directors of the Japanese Dermatological Association (JDA). It held several meetings and evaluations in writing since October 2008, and drafted five guidelines for the diagnosis and treatment including commentaries on wounds in general and the Guidelines for the Diagnosis and Treatment for Pressure Ulcers by taking opinions of the Scientific Committee and Board of Directors of JDA into consideration.

The wound/burn guidelines – 1: Wounds in general

The Japanese Dermatological Association determined to prepare the Wound/Burn Guidelines focusing on treatments, catering to needs for the clinical practice of dermatology. Among these guidelines, “Wounds in General” was intended to explain knowledge necessary “to heal wounds” without specifying particular disorders.

Outline of guidelines for the management of vasculitis and vascular disorders in Japan, 2016 revised edition

The proposal by the 1994 International Chapel Hill Consensus Conference on the Nomenclature of Systemic Vasculitides (CHCC1994) and by the CHCC2012 markedly influenced the classification and way of considering cutaneous vasculitis. In the proposal by the CHCC1994, hypersensitivity angiitis was defined as an equivalent pathological condition to microscopic polyangiitis or cutaneous leukocytoclastic angiitis (CLA), and it was not adopted as a disease name. However, CLA which was positioned as a type of small‐vessel vasculitis is only a pathological name. In the proposal by the CHCC2012, a new category of single‐organ vasculitis included CLA and cutaneous arteritis. Vasculitis allergica cutis (Ruiter) corresponded to CLA and cutaneous polyarteritis nodosa corresponded to cutaneous arteritis. The Japanese Dermatological Association (JDA) prepared guidelines for the management of vasculitis and vascular disorders in 2008 based on the proposal by the CHCC1994 and their original viewpoint of dermatology. The JDA subsequently revised the 2008 edition guidelines in 2016 following publication of the proposal of the CHCC2012 in Japanese. We presented the outline of the 2016 edition guidelines and propose a treatment algorithm for primary vasculitides based on the evaluation of the cutaneous symptoms for cases suspected as primary cutaneous vasculitides, which integrates the 2008 JDA guideline and CHCC2012 classification. This is the secondary English version of the original Japanese manuscript for the guideline for management of vasculitis and vascular disorders published in the Japanese Journal of Dermatology 127(3); 299–415, 2017.

Burden of atopic dermatitis in Japanese adults: Analysis of data from the 2013 National Health and Wellness Survey

Atopic dermatitis is a chronic inflammatory skin disease. The objective of this study was to characterize the burden of atopic dermatitis in Japanese adult patients relative to the general population. Japanese adults (≥18 years) with a self‐reported diagnosis of atopic dermatitis and adult controls without atopic dermatitis/eczema/dermatitis were identified from the 2013 Japan National Health and Wellness Survey. Atopic dermatitis patients were propensity‐score matched with non‐atopic dermatitis controls (1:2 ratio) on demographic variables. Patient‐reported outcome data on comorbidities, mood and sleep disorders, health‐related quality of life, work productivity and activity impairment, and health‐care resource utilization were analyzed in atopic dermatitis patients and matched controls. A total of 638 Japanese adult patients with atopic dermatitis were identified, of whom 290 (45.5%) rated their disease as “moderate/severe” and 348 (54.5%) as “mild”. The analysis cohort comprised 634 atopic dermatitis patients and 1268 matched controls. Atopic dermatitis patients reported a significantly higher prevalence of arthritis, asthma, nasal allergies/hay fever, anxiety, depression and sleep disorders compared with controls (all P < 0.001). Atopic dermatitis patients also reported a significantly poorer health‐related quality of life, higher overall work and activity impairment, and higher health‐care resource utilization (all P < 0.001). Self‐rated disease severity was not associated with disease burden, except for a significantly higher overall work and activity impairment. In conclusion, Japanese adult patients with atopic dermatitis reported a substantial disease burden relative to adults without atopic dermatitis, suggesting an unmet need for effective strategies targeting disease management.

Japanese Dermatological Association Guidelines: Guidelines for the treatment of acne vulgaris 2017

The Guidelines for the Treatment of Acne Vulgaris of the Japanese Dermatological Association was first published in Japanese in 2008 and revised in 2016 and 2017. These guidelines (GL) indicate the standard acne treatments in Japan and address pharmaceutical drugs and treatments applicable or in use in Japan. In these GL, the strength of the recommendation is based on clinical evidences as well as availability in Japanese medical institutions. In the 2016 and 2017 GL, some of the clinical questions were revised, and other questions were added in accordance with approval of topical medicines containing benzoyl peroxide (BPO). Rather than monotherapies of antibiotics, the 2017 GL more strongly recommend combination therapies, especially fixed‐dose combination gels including BPO in the aspects of pharmacological actions and compliance in the acute inflammatory phase to achieve earlier and better improvements. The 2017 GL also indicate to limit the antimicrobial treatments for the acute inflammatory phase up to approximately 3 months and recommend BPO, adapalene, and a fixed‐dose combination gel of 0.1% adapalene and 2.5% BPO for the maintenance phase to avoid the emergence of antimicrobial‐resistant Propionibacterium acnes. The 2017 GL also discuss rosacea, which requires discrimination from acne and a different treatment plan.
