Wound, Pressure Ulcer, and Burn Guidelines-5: Guidelines for the management of lower leg ulcers and varicose veins, second edition.

"Wound, Pressure Ulcer, and Burn Guidelines-5: Guidelines for the management of lower leg ulcers and varicose veins, second edition" is revised from the first edition, which was published in the Japanese Journal of Dermatology in 2011. 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 management of lower leg ulcers and varicose veins. We updated all sections by collecting documents published since the publication of the first edition.

[Efficacy of nivolumab in combination with chemotherapy after radiotherapy for meningeal carcinomatosis in patients with Epstein-Barr virus-associated gastric cancer:a case report].

A 62-year-old man presented with fever and anorexia since July X. Initial treatments were rendered ineffective, and due to altered consciousness and vomiting, he was referred to our hospital. On admission, he manifested delirium, drowsiness, and disorientation.

Post-dialysis fatigue predicts all-cause mortality in patients on chronic hemodialysis.

Introduction: Fatigue is reportedly associated with a poor prognosis in dialysis patients. The aim of the present study was to investigate whether fatigue on dialysis days or non-dialysis days is associated with mortality in patients on chronic hemodialysis.

Methods: This was a prospective study of 134 hemodialysis patients.

Endoscopic treatment of bile duct stones with benign choledochojejunal anastomotic stenosis.

Background And Aims: Endoscopic interventions for bile duct stones (BDSs) with benign choledochojejunal anastomotic stenosis (bCJS) are challenging. Therefore, we investigated endoscopic interventions for BDSs with bCJS.

Methods: Seventeen patients with BDSs with bCJS were retrospectively analyzed.

Effects of adoptive T-cell immunotherapy on immune cell profiles and prognosis of patients with unresectable or recurrent cholangiocarcinoma.

The identification of immune cell profiles (ICP) involved in anti-tumor immunity is crucial for immunotherapy. Therefore, we herein investigated cholangiocarcinoma patients (CCA) who received adoptive T-cell immunotherapy (ATI). Eighteen unresectable or recurrent CCA received ATI of αβ T cells alone or combined with chemotherapy.

Analyzing the relationship between the efficacy of first-line immune checkpoint inhibitors and cumulative sun damage in Japanese patients with advanced BRAF wild-type nonacral cutaneous melanoma: A retrospective real-world, multicenter study.

Background: Efficacy of anti-PD-1 antibody monotherapy (PD1) or anti-PD-1 plus anti-CTLA-4 combination therapy (PD1 +CTLA4) for melanoma is affected by its clinical subtype. The amount of tumor mutation burden (TMB) caused by cumulative sun damage (CSD) is occasionally used to explain this; however, their relationship in Japanese nonacral cutaneous melanoma (NACM) is still unclear.

Objective: To analyze the ICI efficacy and its relationship with CSD of the primary lesion in Japanese patients with NACM.

Development of multiple myeloma after 15 years of treatment for polycythemia vera and successful treatment using bortezomib: A case report.

Multiple myeloma (MM) and polycythemia vera (PV) rarely coexist; the clinical manifestations and treatment of this coexistence have not been described. An 81-year-old woman developed MM 15 years after undergoing PV treatment and was successfully treated using bortezomib. Herein, we share our experience of treating MM under such unusual conditions.

Narrower clinical margin in high or very high-risk squamous cell carcinoma: a retrospective, multicenter study of 1,000 patients.

Background And Objectives: In cutaneous squamous cell carcinoma (cSCC), adherence to guideline-recommended fixed surgical margins is often difficult, and narrower margins are preferable. This study aimed to evaluate relapse and disease-specific death with narrower margins for high or very high-risk cSCC.

Patients/methods: We retrospectively investigated high or very high-risk cSCC patients who underwent tumor excision.

Lichen Planopilaris Arising between Two Linear Surgical Scars.

Lichen planopilaris (LPP) is a type of lymphocytic cicatricial alopecia, which can occur at unusual sites. It can be difficult to diagnose at an early stage and may be misdiagnosed as seborrheic dermatitis or psoriasis in early stages before alopecia occurs. We report a rare case in which alopecia occurred between two long surgical scars on the scalp several years after surgery.

Biliary stones or ulcers at the choledochojejunal anastomotic site involving the jejunal mucosa at stent removal may be recurrent factors in patients with benign choledochojejunal anastomotic stenosis undergoing endoscopic biliary stenting using fully covered self-expandable metal stents.

Background: Temporary fully covered self-expandable metal stent (FCSEMS) placement is performed for benign choledochojejunal anastomotic stenosis (bCJS). However, recurrence may develop after stricture resolution. We investigated endoscopic biliary stenting using FCSEMS for bCJS.

A real-world study on the safety of the extended dosing schedule for nivolumab and pembrolizumab in patients with solid tumors.

Background: In addition to 2-weekly nivolumab 240 mg or 3-weekly pembrolizumab 200 mg, extended dosing intervals of 4-weekly nivolumab 480 mg or 6-weekly pembrolizumab 200 mg were approved. To date, the clinical safety of the extended dosing schedules of immune checkpoint inhibitors (ICIs) has not been adequately investigated in patients with solid tumors.

Methods: This real-world study enrolled patients with solid tumors who received nivolumab 480 mg every 4 weeks or pembrolizumab 400 mg every 6 weeks at the Kyoto Prefectural University of Medicine in Japan, between August 2020 and December 2021.
