Bullous pemphigoid is an autoimmune condition whereby the immune system forms antibodies that target the skin, resulting in the formation of blisters in a generalized and symmetric pattern. Localized bullous pemphigoid can occur in special circumstances. Here, we describe two patients that developed localized bullous pemphigoid in one lower extremity following orthopedic surgery. We propose that underlying edema following orthopedic surgery is a potential trigger for localized bullous pemphigoid. 相似文献

Epidermolysis bullosa is a rare blistering skin disorder that is challenging to manage because skin fragility and repeated wound healing cause itching, pain, limited mobility, and recurrent infections. Cannabidiol, an active cannabinoid found in cannabis, is postulated to have antiinflammatory and analgesic effects. We report 3 cases of self‐initiated topical cannabidiol use in patients with epidermolysis bullosa in an observational study. One patient was weaned completely off oral opioid analgesics. All 3 reported faster wound healing, less blistering, and amelioration of pain with cannabidiol use. Although these results demonstrate promise, further randomized, double‐blind clinical trials are necessary to provide scientific evidence of our observed benefits of cannabidiol for the treatment of epidermolysis bullosa. 相似文献

A 44-year-old woman with refractory follicular lymphoma underwent allogeneic stem cell transplantation (SCT) and achieved
complete remission. Grade III acute graft-versus-host disease (GVHD) developed on day 23, but no chronic GVHD occurred. The
patient developed severe erosion with bullous lesions in the oral cavity 18 months after SCT. At that time, the lymphoma remained
in complete remission, and she had no clinical or laboratory findings suggesting chronic GVHD. A biopsy of the oral mucosa
showed moderate lymphoplasmacytic infiltration and subepidermal bullae, and direct immunofluorescence staining demonstrated
linear deposition of C3 at the dermo-epidermal junction. An immunoblotting assay using human epidermal extracts confirmed
the presence in her serum of an antibody against the 230-kd bullous pemphigoid antigen 1 (BPAG1). A diagnosis of cicatricial
pemphigoid (CP) was made, and complete resolution of the CP was achieved with pred-nisolone therapy. The occurrence of autoimmune
blistering diseases is rare after allogeneic SCT. 相似文献

Kindlin-1 is an epithelium-specific phosphoprotein and focal adhesion adaptor component. Mutations in the corresponding gene (KIND1) cause Kindler syndrome (KS), which is manifested by skin blistering, poikiloderma, photosensitivity and carcinogenesis. Some patients also exhibit gastrointestinal symptoms, but it has remained unclear whether these represent a feature of Kindler syndrome or a coincidence. We examined kindlin-1 in human gastrointestinal epithelia and showed that it is involved in the aetiopathology of Kindler syndrome-associated colitis. Kindlin-1 expression was assessed by indirect immunofluorescence, western blot and RT-PCR. Kindlin-1 is expressed in oral mucosa, colon and rectum. Both the full-length 74 kDa kindlin-1 protein and a 43 kDa isoform were detected in CaCo2 cells, the latter resulting from alternative splicing. In the first months of life, patients (homozygous for null mutations) had severe intestinal involvement with haemorrhagic diarrhoea and showed morphological features of severe ulcerative colitis. Later in childhood, histopathology demonstrated focal detachment of the epithelium in all segments of the colon, chronic inflammation and mucosal atrophy. These findings define an intestinal phenotype for Kindler syndrome as a consequence of a primary epithelial barrier defect. The different clinical intestinal manifestations in Kindler syndrome patients may be explained by partial functional compensation of kindlin-1 deficiency by the intestinal isoform or by the presence of truncated mutant kindlin-1. 相似文献

The wrinkling and delamination of stiff thin films adhered to a polymer substrate have important applications in “flexible electronics.” The resulting periodic structures, when used for circuitry, have remarkable mechanical properties because stretching or twisting of the substrate is mostly accommodated through bending of the film, which minimizes fatigue or fracture. To date, applications in this context have used substrate patterning to create an anisotropic substrate-film adhesion energy, thereby producing a controlled array of delamination “blisters.” However, even in the absence of such patterning, blisters appear spontaneously, with a characteristic size. Here, we perform well-controlled experiments at macroscopic scales to study what sets the dimensions of these blisters in terms of the material properties and explain our results by using a combination of scaling and analytical methods. Besides pointing to a method for determining the interfacial toughness, our analysis suggests a number of design guidelines for the thin films used in flexible electronic applications. Crucially, we show that, to avoid the possibility that delamination may cause fatigue damage, the thin film thickness must be greater than a critical value, which we determine. 相似文献

Two patients with clinical and laboratory evidence of co-existing lichen sclerosus and eicatricial pemphigoid are reported. Autoimmune bullous diseases affecting the vulva may mimic lichen sclerosus but in these two patients both diseases were present. These two diseases have not previously been reported simultaneously to date. 相似文献

Kindler syndrome: a focal adhesion genodermatosis 总被引:1,自引:0,他引:1
J.E. Lai-Cheong A. Tanaka G. Hawche P. Emanuel C. Maari† M. Taskesen‡ S. Akdeniz‡ L. Liu J.A. McGrath 《The British journal of dermatology》2009,160(2):233-242
Kindler syndrome (OMIM 173650) is an autosomal recessive genodermatosis characterized by trauma-induced blistering, poikiloderma, skin atrophy, mucosal inflammation and varying degrees of photosensitivity. Although Kindler syndrome is classified as a subtype of epidermolysis bullosa, it has distinct clinicopathological and molecular abnormalities. The molecular pathology of Kindler syndrome involves loss-of-function mutations in a newly recognized actin cytoskeleton-associated protein, now known as fermitin family homologue 1, encoded by the gene FERMT1 . This protein mediates anchorage between the actin cytoskeleton and the extracellular matrix via focal adhesions, and thus the structural pathology differs from other forms of epidermolysis bullosa in which there is a disruption of the keratin intermediate filament–hemidesmosome network and the extracellular matrix. In the skin, fermitin family homologue 1 is mainly expressed in basal keratinocytes and binds to the cytoplasmic tails of β1 and β3 integrins as well as to fermitin family homologue 2 and filamin-binding LIM protein 1. It also plays a crucial role in keratinocyte migration, proliferation and adhesion. In this report, we review the clinical, cellular and molecular pathology of Kindler syndrome and discuss the role of fermitin family homologue 1 in keratinocyte biology. 相似文献

静脉注射免疫球蛋白作为一种免疫调节剂可治疗多种免疫相关性疾病。自身免疫性疱病是在皮肤科中使用静脉注射免疫球蛋白最有效的疾病之一。该方法不良反应较少且大多有自限性,为一些常规治疗禁忌或无效的患者提供了安全有效的治疗选择。但其确切的作用机制尚未完全明了,近年来的研究显示可能与抗独特型抗体、中和Fc受体、调节细胞因子网络、影响发病中的细胞凋亡过程等有关。 相似文献
