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.

[A case of skin cancer diagnosed 21 days after renal transplantation].

The patient was a 67-year-old man who was started on peritoneal dialysis for treatment of diabetic nephropathy in March 2010. He received an ABO-compatible living-donor kidney transplant from his wife in October 2010. The immunosuppressive regimen consisted of tacrolimus, mycophenolate mofetil, steroid and basiliximab. Before the operation, a bump on his forehead/temple region that was increasing in size for years was noted. The bump had a scaly surface and the top of the bump was sloughed on postoperative day 14. Histological examination suggested malignancy. On postoperative day 21, a skin biopsy was performed by dermatologists and squamous cell carcinoma was confirmed. On postoperative day 36, wide excision and transposition flap procedures were performed by the plastic surgeon. At 15 months after transplantation, the kidney graft was functioning well with a serum creatinine level of 0.84 mg/dl and there was no sign of recurrence of the squamous cell carcinoma.
