Inflammatory myopathy is rare in localized scleroderma. We report 2 new cases of regional inflammatory myopathy associated with localized scleroderma and review 10 reported cases of localized scleroderma associated with an inflammatory myopathy with regional muscle involvement, more often in the upper extremities. Serum creatine kinase was mildly elevated or normal. Histopathology often showed perimysial inflammation and plasma cell infiltration. These cases demonstrate that inflammatory myopathy should be considered in patients with localized scleroderma and regional muscle weakness, pain or atrophy. Muscle biopsy can confirm the diagnosis of myositis, which if identified, will require anti-inflammatory and/or immunosuppressive therapy. 相似文献

ABSTRACTSclerodermatous graft versus host disease (sclGVHD) is a debilitating complication of hematopoietic stem cell transplant and is characterized by skin thickening and fibrosis that can result in severe contractures. While immunosuppressive therapy remains a mainstay of treatment, the disease course often progresses and, in severe cases, renders patients immobile and wheelchair-bound. Lasers that can target sclerotic lesions to improve tissue pliability and restore range of motion are a promising potential treatment for sclGVHD. Fractional CO2 lasers promote selective collagen remodeling by creating microcolumns of thermal injury that stimulate a wound healing response. Here, we present 2 patients with sclGVHD who underwent treatment with fractional ablative CO2 laser. In this pilot case series demonstrating the novel use of CO2 laser for severe, refractory sclGVHD, two patients were treated with fractional ablative CO2 laser to a focal area of sclerosis. One patient also received clobetasol ointment under occlusion in between treatments. Both patients reported marked subjective improvement in pain and mobility. Objective measurements were recorded for patient 2 who gained roughly 10 degrees of extension and 2 degrees of flexion, as well as a 10% reduction in skin thickness in the treated area. CO2 laser therapy with or without clobetasol ointment under occlusion is a promising treatment modality for sclGVHD. 相似文献

Linear scleroderma of the head and face is a rare connective tissue disorder characterized by linear depressed scarring in the frontoparietal area of the face. Here, we report a patient with linear scleroderma of the head and face with neurological symptoms such as spontaneous epilepsy and numbness of the right limb as well as the presence of white matter lesions. The patient underwent computed tomography and 3.0-T magnetic resonance examinations including diffusion weighted imaging, diffusion tensor imaging, and perfusion imaging. The imaging findings suggested a disrupted fiber tract and decreased relative cerebral blood flow. Our observation may help to improve the diagnosis and treatment of linear scleroderma of the head and face. 相似文献

Systemic sclerosis and morphea are connective tissue diseases characterized by tightening, thickening, and hardening of the skin, leading to significant morbidity. Unfortunately, current treatment options have limited efficacy for many patients. Cutaneous manifestations of these diseases arise from excess collagen deposition and fibrosis in the skin, through pathogenic mechanisms which have yet to be extensively detailed at the causal immune and cellular levels. Research elucidating the mechanism of action of retinoic acid on collagen production in the skin and case series highlighting the success of retinoic acid on the skin manifestations of systemic sclerosis and on morphea demonstrate its promise as a treatment. Herein they will briefly review the treatment options for both systemic sclerosis and morphea, and will discuss the potential of retinoic acid as a therapy and the supporting evidence from the literature, highlighting the previously published basic science and clinical studies investigating the role of retinoic acid in the treatment of sclerotic skin diseases. 相似文献

系统性硬化症是一种自身免疫病,以多系统纤维化、小血管病变、血清自身抗体阳性为主要特点。目前其病因尚未十分清楚,越来越多的证据显示可能有血管病变、炎性反应、纤维化、自身免疫四大机制参与并相互作用。在研究系统性硬化症的发病机制、探索新药治疗效果时需要用到动物模型来模拟病理生理过程,而每一种模型都有其特点却又不完美。本文将根据建模方法分类介绍一些经典的和创新的模型,以及它们各自的特点、应用价值,为研究者选择最合适的动物模型提供帮助。 相似文献
