腹壁坏死性筋膜炎的认识与治疗

坏死性筋膜炎是皮肤软组织感染中最为凶险的类型，往往并发脓毒症休克和多器官功能障碍，死亡率较高。常见的坏死性筋膜炎是社区获得性感染，而临床上发生在腹壁的坏死性筋膜炎也并不罕见，如发生于经皮内镜胃造口管或者造口周围的坏死性筋膜炎，也有发生于整形手术、妇科手术、结直肠手术后的坏死性筋膜炎。腹部手术后发生消化道瘘并发腹壁坏死性筋膜炎，病死率高，值得重视。尽早诊断与及时实施包括坏死组织清除、消化道瘘引流以及腹腔开放在内的感染源控制措施至关重要。     

Maintenance Therapy for Cutaneous T-cell Lymphoma After Total Skin Electron Irradiation: Evidence for Improved Overall Survival With Ultraviolet Therapy

BackgroundTreatment of cutaneous T-cell lymphoma (CTCL) with total skin electron beam (TSEB) therapy has been associated with deep responses but short progression-free intervals. Maintenance therapy might prolong the response duration; however, limited data assessing the outcomes with maintenance therapy after TSEB are available. We evaluated the effect of maintenance therapy on the outcomes for patients with CTCL receiving TSEB therapy.Materials and MethodsWe conducted a single-center retrospective analysis of 101 patients with CTCL who had received TSEB therapy from 1998 to 2018 at the Winship Cancer Institute of Emory University and compared the overall survival (OS) and progression-free survival (PFS) for patients had received maintenance therapy, including retinoids, interferon, ultraviolet therapy, nitrogen mustard, and extracorporeal photopheresis compared with those who had not.ResultsWe found that pooled maintenance therapies improved PFS (hazard ratio [HR], 0.60; P = .026) but not OS (median HR, 0.73; P = .264). The median PFS and OS was 7.2 months versus 9.6 months and 2.4 years versus 4.2 years for the no maintenance and maintenance groups, respectively. On exploratory analysis of the individual regimens, ultraviolet therapy was associated with improved OS (HR, 0.21; P = .034) and PFS (HR, 0.26; P = .002) compared with no maintenance.ConclusionAmong the patients with CTCL who had received TSEB therapy, maintenance therapy improved PFS for all patients, and ultraviolet-based maintenance improved both PFS and OS in a subset of patients.
