INTRODUCTION: Epidermal grafting has several advantages over full-thickness or split-thickness grafts in the treatment of complex non-healing wounds. These include the low risk of donor site complications, minimal patient discomfort, and abstention from the operating room. Traditionally, the lack of reliable epidermal harvesting techniques has limited its clinical utilization. The development of an automated suction blister epidermal graft (SBEG) harvesting device may facilitate clinical utilization of this technique...

Extensive mortality of whitebark pine, beginning in the early to mid-2000s, occurred in the Greater Yellowstone Ecosystem (GYE) of the western USA, primarily from mountain pine beetle but also from other threats such as white pine blister rust. The climatic drivers of this recent mortality and the potential for future whitebark pine mortality from mountain pine beetle are not well understood, yet are important considerations in whether to list whitebark pine as a threatened or endangered species. We sought to increase the understanding of climate influences on mountain pine beetle outbreaks in whitebark pine forests, which are less well understood than in lodgepole pine, by quantifying climate-beetle relationships, analyzing climate influences during the recent outbreak, and estimating the suitability of future climate for beetle outbreaks...

BACKGROUND: Mucous membrane pemphigoid (MMP) is considered an autoimmune blistering disease that predominantly affects mucous membranes. Various treatments are available for controlling the diseases, but not all of them may respond. MATERIALS AND METHODS: PubMed and Google Scholar were searched for all the associated studies until 2015, using the keywords such as "cicatricial pemphigoid" or "ocular pemphigoid" or "mucous membrane pemphigoid" or "MMP" and "intravenous immunoglobulin" or "IVIg" to find all the relevant studies...

Pemphigus vulgaris (PV), pemphigus foliaceus (PF), and paraneoplastic pemphigus (PNP) are a group of rare and fatal blistering diseases involving autoantibodies that target desmosomal proteins. The pathogenesis of pemphigus involves the production of activated B-cells and IgG with stimulation by IL-4 by T-helper 2 cells. Clinically these diseases present most often with epidermal erosions of the mucosae and skin caused by rapid rupturing of flaccid bullae. These lesions correlate histologically with splits forming in the epidermis, leaving a blister roof composed of a few cell layers...

Novel forest decline is increasing due to global environmental change, yet the causal factors and their interactions remain poorly understood. Using tree ring analyses, we show how climate and multiple biotic factors caused the decline of whitebark pine (Pinus albicaulis) in 16 stands in the southern Canadian Rockies. In our study area, 72% of whitebark pines were dead and 18% had partially dead crowns. Tree mortality peaked in the 1970s; however, the annual basal area increment of disturbed trees began to decline significantly in the late 1940s...

Dystrophic epidermolysis bullosa (DEB) is a heritable skin disease manifesting with sub-lamina densa blistering, erosions and chronic ulcers. COL7A1, encoding type VII collagen, has been identified as the candidate gene for DEB. In this study, we have identified COL7A1 mutations in a large multi-ethnic cohort of 152 extended Iranian families with high degree of consanguinity. The patients were diagnosed by clinical manifestations, histopathology and immunoepitope mapping. Mutation detection consisted of a combination of a single nucleotide polymorphism-based whole genome homozygosity mapping, Sanger sequencing and gene targeted next generation sequencing...

I read with interest a report by von Köckritz et al(1) . Tetracycline therapy, particularly in autoimmune blistering conditions, has become an acceptable treatment modality among elderly individuals, particularly those with osteoporosis, DM, and hypertension. This drug has also been given in combination with immunosuppressive treatment for more rapid tapering of the latter(2) .Minocycline besides having antimicrobial activity, it possesses anti-inflammatory and anti-apoptotic properties and causes inhibition of proteolysis, angiogenesis, and collagenase, and ability to induce read-through of premature stop mutations(3) ...

BACKGROUND: Cardiovascular disease occurs at lower incidence in premenopausal females compared with age-matched males. This variation may be linked to sex differences in inflammation. We prospectively investigated whether inflammation and components of the inflammatory response are altered in females compared with males. METHODS: We performed 2 clinical studies in healthy volunteers. In 12 men and 12 women, we assessed systemic inflammatory markers and vascular function using brachial artery flow-mediated dilation (FMD)...

BACKGROUND: Epidermolysis bullosa simplex is a skin-blistering disorder caused by mutations in keratin (K)14 or K5. Treatment with nuclear factor (erythroid-derived 2)-like 2 inducer sulforaphane ameliorated skin blistering in Krt14-null mice, correlating with induction of K17. To be therapeutically useful for epidermolysis bullosa simplex, topical broccoli sprout extract (BSE), enriched for sulforaphane, would ideally induce the expression of homologous keratins (eg, K6, K17, K16) in the basal layer of human epidermis without impacting expression of defective keratins (K5/K14)...

The genetic basis of epidermolysis bullosa, a group of genetic disorders characterized by the mechanically induced formation of skin blisters, is largely known, but a number of cases still remain genetically unsolved. Here, we used whole-exome and targeted sequencing to identify monoallelic mutations, c.1A>G and c.2T>C, in the translation initiation codon of the gene encoding kelch-like protein 24 (KLHL24) in 14 individuals with a distinct skin-fragility phenotype and skin cleavage within basal keratinocytes...

BACKGROUND: Plectin, a large linker protein found in many tissues, acts to connect components of the cytoskeleton to each other. In the epidermis, plectin binds keratin intermediate filaments to hemidesmosomes. A deficiency of plectin in the skin leads to blister formation in the basal layer and the disease epidermolysis bullosa simplex (EBS). HYPOTHESIS/OBJECTIVES: To describe a novel blistering disease that arose spontaneously in a litter of puppies. ANIMALS: Two female and one male 20-day-old Eurasier puppies, from a litter of six, were presented for evaluation of failure to thrive and then euthanized due to poor prognosis...

Autoimmune paraneoplastic and neoplasm-associated skin syndromes are characterized by autoimmune-mediated cutaneous lesions in the presence of a neoplasm. The identification of these syndromes provides information about the underlying tumor, systemic symptoms, and debilitating complications. The recognition of these syndromes is particularly helpful in cases of skin lesions presenting as the first sign of the malignancy, and the underlying malignancy can be treated in a timely manner. Autoimmune paraneoplastic and neoplasm-associated bullous skin syndromes are characterized by blister formation due to an autoimmune response to components of the epidermis or basement membrane in the context of a neoplasm...

Bullous pemphigoid (BP) is an acquired, autoimmune, subepidermal blistering disorder. A possible paraneoplastic association has been suggested; however, debate remains regarding the precise relationship of these neoplasms with BP. We present a case of recalcitrant BP in a 67-year-old man with a pancreatic neoplasm that was found to be a lymphoepithelial cyst. Immunoperoxidase staining of the cyst demonstrated C3d along the basement membrane of the stratified squamous epithelium, suggesting that the BP may have involved the lymphoepithelial cyst itself...

Pemphigus is an autoimmune blistering skin disease that is strongly associated with different environmental factors. Among these, nutritional factors are considered to trigger pemphigus; however, their role may be underestimated. Investigated more recently in conventional medicine, this causative bond between dietary factors and blistering skin diseases was mentioned by Persian scholars such as Avicenna a thousand years ago. Avicenna, a well-known Persian physician and philosopher, who could be considered a pioneer in dermatology, discussed skin diseases in a chapter in The Canon of Medicine...

Pemphigus vulgaris is a chronic disease that is characterized by flaccid blisters and erosions, caused by immunoglobulin G autoantibodies against epidermal components. It is highly unusual in the pediatric population; it represents the 1.4 - 2.9% of the total cases. We present a case of pemphigus vulgaris in a 12 year old girl, which has implied a challenge both in its diagnosis and in its treatment.

Bullous pemphigoid (BP) is an autoimmune blistering skin disease that is more common in elderly individuals. The aim of this study was to determine the functional activity of eosinophils in patients with BP compared with healthy donors. Blood, skin and blister-derived eosinophils were strongly activated in patients with BP, seen by increased surface expression of CD69 compared with controls. CD11b was also increased in BP blood eosinophils, which may explain the striking accumulation of eosinophils in BP (1×10-6 per ml blister fluid)...

Context • The hallmark of herpes zoster (HZ) is a painful, blistering rash, but neuropathic pain can persist beyond the clearing of the rash and is diagnosed as postherpetic neuralgia (PHN), a chronic pain syndrome. However, the pain in PHN is often refractory to treatment. Objective • The study investigated the ability of Uyakujunkisan (UJS), or Kampo medicine, a traditional herbal medicine, to treat PHN successfully. Design • The study was observational, with discussion of 2 cases. Setting • The study took place in the Department of Japanese Oriental Medicine at Gunma Central and General Hospital (Maebashi, Gunma, Japan)...

Pemphigus is an autoimmune disease that causes blistering and is life-threatening if left untreated. Nowadays, finding a promising treatment for pemphigus remains a serious challenge. Various treatments are currently recommended to treat this disease, but they rarely lead to complete and durable remission. Regulatory cells appear to have a critical role in numerous autoimmune diseases, so it is possible that promotion of these cells may induce remission. This study presents a new approach to treating pemphigus that has not been discussed to date...

Microcephaly (MCPH) is a developmental disorder characterized by reduced brain size and intellectual disability. A proportion of microcephaly is caused by defects in a single gene. Microcephaly 2 (MCPH2) is one of the most frequent subtypes of MCPH.WD repeat-containing protein 62 gene (WDR62) is the most frequently mutated gene in MCPH2 patients. Phenotypes involving dermatological changes in MCPH2 have not been reported. We have identified and investigated a 5-year-old Chinese girl with markedly reduced brain size (86% of normal size), intellectual disability and psychomotor developmental delay...
