Wound, pressure ulcer and burn guidelines - 1: Guidelines for wounds in general, second edition.

The Japanese Dermatological Association prepared the clinical guidelines for the "Wound, pressure ulcer and burn guidelines", second edition, focusing on treatments. Among them, "Guidelines for wounds in general" is intended to provide the knowledge necessary to heal wounds, without focusing on particular disorders. It informs the basic principles of wound treatment, before explanations are provided in individual chapters of the guidelines. We updated all sections by collecting references published since the publication of the first edition. In particular, we included new wound dressings and topical medications. Additionally, we added "Question 6: How should wound-related pain be considered, and what should be done to control it?" as a new section addressing wound pain, which was not included in the first edition.

Wound, pressure ulcer and burn guidelines - 6: Guidelines for the management of burns, second edition.

"Wound, pressure ulcer and burn guidelines - 6: Guidelines for the management of burns, second edition" is revised from the first edition which was published in the Japanese Journal of Dermatology in 2016. The guidelines were drafted by the Wound, Pressure Ulcer and Burn Guidelines Drafting Committee delegated by the Japanese Dermatological Association, and intend to facilitate physicians' clinical decisions in preventing, diagnosing and treating burn injury. All sections are updated by collecting documents published since the publication of the first edition. Especially, the recommendation levels of dressing materials newly covered by the Japanese national health insurance are mentioned. In addition, the clinical questions (CQ) regarding the initial treatment of electrical (CQ15) and chemical burns (CQ16), and also the use of escharotomy (CQ22), are newly created.

Wound, pressure ulcer and burn guidelines - 4: Guidelines for the management of connective tissue disease/vasculitis-associated skin ulcers.

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.

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 - 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.

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 - 5: Guidelines for the management of lower leg ulcers/varicose veins.

Varicose veins are treated at multiple clinical departments, but as patients often visit the dermatology clinic first due to leg ulcers, the present Guidelines for the Management of Lower Leg Ulcers/Varicose Veins were prepared in consideration of the importance of the dermatologist's role. Also, the disease concept of chronic venous insufficiency or chronic venous disorders and the CEAP classification of these disorders are presented. The objective of the present guidelines is to properly guide the diagnosis and treatment of lower leg ulcers/varicose veins by systematically presenting evidence-based recommendations that support clinical decisions.

A case of lower-extremity deep burn wounds with periosteal necrosis successfully treated by use of allogenic cultured dermal substitute.

In patients with burns, bone exposure accompanies serious problems which occasionally lead to amputation. We present a case of an 82-year-old woman who sustained 22% of total body surface area flame burns on her bilateral lower extremities with bone exposure. Despite fascial excision and mesh skin graft, muscles, bones, and tendons were widely exposed on her right leg. The wound was infected by methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa. To promote wound healing, we applied an allogeneic cultured dermal substitute (CDS) to the wound surface once weekly, resulting in healthy granulation except for the exposed bone area of the right anterior tibia. We then shaved the cortex of the exposed bone surface until bone marrow bleeding, and grafted mesh skin in combination with CDS. Finally, all wounds healed without osteomyelitis. The use of CDS to treat deep burns exposing bone surface may expand reconstructive options for extremities that otherwise might have been amputated.

Metastatic extramammary Paget's disease treated with paclitaxel and trastuzumab combination chemotherapy.

In the treatment of metastatic breast cancer, trastuzumab, a recombinant monoclonal antibody against human epidermal growth factor receptor 2 (HER2), is effective when tumor cells overexpress HER2 protein. Although some cases of extramammary Paget's disease (EMPD) also express HER2 protein, no case of EMPD has been reported to be treated with trastuzumab. A 75-year-old man who suffered from EMPD of the scrotum and inguinal region underwent a local excision and lymph node dissection. Tumor cells invaded the dermis and lymph nodes. Although he was postoperatively treated with adjuvant chemotherapies, metastatic skin lesions appeared and spread over his left thigh, rapidly and widely. Tumor cells disseminated along lymph vessels in the dermis and overexpressed HER2 protein. We administered paclitaxel and trastuzumab according to a protocol for HER2-positive metastatic breast cancers. The skin metastasis dramatically decreased during the regimen and a histopathological examination showed that most of HER2-positive tumor cells diminished. Six months later, metastases were found in the central nervous system (CNS), but no other metastases were found in the skin, visceral organs or lymph nodes. Trastuzumab and paclitaxel-combination with the assessment of central nervous system lesions should be considered as an option for the treatment of HER2-positive EMPD.
