    Abstract Vibrio spp. is a pathogen rarely isolated in cancer patients, and in most cases it is associated with haematological diseases. Cutaneous manifestations of this organism are even rarer. We report a case of Non-O1 Vibrio cholerae inguinal skin and soft tissue infection presenting bullous skin lesions in a young type II diabetic patient with a penis squamous cell carcinoma having a seawater exposure history.

    Autoimmune and nonautoimmune bullous diseases can both be associated with significant morbidity and mortality. Although our understanding of the pathogenic mechanisms of these diseases has increased tremendously, there is still much to learn about the various factors affecting their onset, course, and therapy. In recent years, increasing information has been published about the effect of vitamins, minerals, and other nutrients on bullous skin diseases. Some factors are believed to be inducers (thiol and phenol-containing foods in pemphigus), whereas others are believed to be protective (antioxidants in cutaneous porphyrias). This contribution reviews the evidence in the literature of the role of various dietary factors in bullous diseases, including the nonautoimmune and the deficiency dermatoses. Additional studies and new investigations are needed to provide a better understanding of the specific associations of dietary factors with bullous diseases and better management for patients affected by these conditions.

    Erythema nodosum leprosum (ENL) is an immune complex-mediated reaction that may complicate the course of multibacillary leprosy. Bullous lesions in Type II reaction, though reported, are exceedingly rare. We report the case of a 32 year old female patient who presented initially at our OPD with erythema nodosum. Cutaneous examination revealed impaired sensation over dorsum of right foot and thickened right lateral popliteal nerve. Slit skin smear (SSS) from ear lobes revealed AFB with a bacteriological index of 2+. She was started on MDT, tablet ofloxacin 200 mg twice a day, and 30 mg oral prednisolone. Two months later, she presented with generalised pruritus, large target lesions over the back, and hemorrhagic bullae over lower extremities and annular pattern of bullae, over both arms. A SSS was repeated which was positive for AFB. Histopathology from bullous lesions was consistent with ENL. Direct Immunofluorescence (DIF) study was negative. Our patient improved rapidly after she was started on thalidomide 100 mg twice daily, with withdrawal of ofloxacin. Erythema Multiforme (EMF) and annular bullous lesions have been reported in patients on treatment with ofloxacin. This case is being presented due to the unusual and varied manifestation of Type II lepra reaction in a 34 year old female patient.

    Full Text Available A 42-year-old male developed hemorrhagic bullae and erosions while in alcohol induced coma. The lesions were limited to areas of the body in prolonged contact with the ground in the comatose state. He developed rhabdomyolysis, progressing to acute renal failure (ARF. Histopathological examination of the skin showed spongiosis, intraepidermal vesicles, and necrosis of eccrine sweat glands with denudation of secretory epithelial lining cells. With supportive treatment and hemodialysis, the patient recovered in 3 weeks time. This is the first reported case of bullous lesions and sweat gland necrosis occurring in alcohol-induced coma complicated by rhabdomyolysis and ARF.

    Linear IgA bullous dermatosis (LAD) is an acquired, heterogeneous, subepidermal blistering disease characterized by linear IgA deposits at the dermoepidermal basement membrane zone (BMZ), often with circulating IgA antibodies to the BMZ. The pathogenetic mechanism, possibly related to the immunophenotype of infiltrating cells, as well as the potential role of cytokines in determining bullous lesions, have not yet been elucidated. An immunohistochemical study was performed with a large panel of monoclonal antibodies [to CD3, CD4, CD8, CD25, CD1a, CD30, CD54, CD50, endothelial leucocyte adhesion molecule-1, vascular cell adhesion molecule-1, myeloperoxidase (MPO), eosinophil cationic protein EG1 and EG2, tryptase, HLA-DR, human interleukin (IL)-3, human IL-5, human IL-8, human IL-4, tumour necrosis factor (TNF)-alpha, interferon (IFN)-gamma and granulocyte/macrophage colony-stimulating factor] using the alkaline phosphatase-antialkaline phosphatase procedure on lesional and perilesional skin of nine patients (one male, eight female; age range 8 months-80 years) with clinical, histological and immunofluorescent proven LAD. The predominant infiltrating cells, distributed mostly inside and below the bullae, were neutrophils and eosinophils which showed intense activation (MPO +, EG1 +, EG2 +). The lymphocytic infiltrate, consisting principally of CD4 +, HLA-DR + and CD30 + T cells, had a predominantly perivascular distribution. Proinflammatory cytokines, such as TNF-alpha and IFN-gamma, showed a moderate focal expression on the dermal perivascular sites; IL-8 was found to have a particularly intense staining on all the epidermal cell layers and at perivascular and vascular sites. Other cytokines, such as IL-4 and IL-5, showed a prevalent intracytoplasmic staining on some cells of the dermal infiltrate (probably mastocytes and lymphocytes), and at the dermal-epidermal separation sites there was also an intense scattered distribution of IL-5.

    Full Text Available The prototypic bullous skin diseases, pemphigus vulgaris, pemphigus foliaceus, and bullous pemphigoid, are characterized by the blister formation in the skin and/or oral mucosa in combination with circulating and deposited autoantibodies reactive with (hemidesmosomes. Koch’s postulates, adapted for autoimmune diseases, were applied on these skin diseases. It appears that all adapted Koch’s postulates are fulfilled, and, therefore, these bullous skin diseases are to be considered classical autoimmune diseases within the wide and expanding spectrum of autoimmune diseases.

  10. The effectiveness of thin-section computed tomography in diagnosing bullous lesions in patients with spontaneous pneumothorax

    International Nuclear Information System (INIS)

    We investigated the effectiveness of this-section computed tomography (CT) for the diagnosis of bullous lesions in patients with spontaneous pneumothorax. The study group consisted of 74 patients. Apical regions of the lung were scanned for lesions by thin-section CT prior to operation. The presence, number, and locations of bullous lesions were assessed. Bullous lesions were also classified into 2 groups according to their shape as demonstrated by CT findings. Operative findings confirmed that 73 of the 74 patients had bullous lesions. Of these, 33 had a single bulla and 40 had multiple bulla. Thin-section CT accurately detected the presence and location of the bullous lesions, accurately identified the number in all but 6 patients with multiple bulla (accuracy: 91.8%), and also classified them accurately by type. Precise evaluations of bullous lesions are crucial to the treatment of patients with spontaneous pneumothorax. The presence of bullous lesions, as well as their location and shape, are important factors in determining whether to operate or not. Such information also allows for a better understanding of the surgical options available. Our study demonstrated that thin-section CT of apical regions of the lung is an effective diagnostic procedure for patients with spontaneous pneumothorax. ((author)

    A 67-year-old woman with a left-sided hemiplegia had localized bullous pemphigoid demonstrating typical clinical lesions on the left pretibial skin and the radial-side skin of the right forearm. The histology showed a subepidermal blister with extensive hyperkeratosis, hypergranulosis, and acanthosis. Direct immunofluorescence revealed distinct linear deposits of IgG and C3 at the dermo-epidermal junction in the perilesional skin and in the roof of the blisters, but few deposits in nonlesional skin. Electron microscopy revealed separation in the lamina lucida. Indirect immunofluorescence of type VII collagen showed its localization in the blister floor. The distribution of the 180-KD bullous pemphigoid antigen (BPA) and beta 4 integrin, hemidesmosomal transmembrane proteins, were studied in the lesional skin by indirect immunofluorescence. Both 180-KD BPA and beta 4 integrin were localized in the blister roof. By immunoelectron microscopy, beta 4 integrin was detected in small groups on the cell surface facing the blister cavity. Since the epitope of the monoclonal antibody to 180-KD BPA used here is known to be localized at a distance of 20 to 50 nm from the membrane surface and this epitope retained in the blister roof, it appears that the blister was produced in the deep lamina lucida. The lesions were cleared with topical 0.05% clobetasole propionate ointment.

    Scabies is a common contagious cutaneous disease and usually affects the young, characterized by polymorphous lesions that may present as burrows, pruritic papules, and inflammatory nodules. Bullous scabies (BS) is its rather rare subtype, mimicking bullous pemphigoid. We report a 15-year-old Chinese boy presenting with 1-month history of pruritic bullae on his penile skin, showing poor response to both topical steroids and systemic antihistamines, but cured by sulfur ointment alone. No recurrence occurred in the 5 years of follow-up. We also reviewed the published cases. Up to date, 44 cases, including the present, have been reported. Of them, 30 were male and 14 were female. The age range was from 1 to 89 years old, with a median age of 70.6 years. The bullous lesions may involve the arms, legs, trunk, genitals, feet, buttocks, thighs, neck, inguinal folds, and may even be generalized. Trunk and extremities are the most common involved locations. Facial or mucosa involvement had never been reported. The histological findings present as a subepidermal split with variable inflammatory infiltrate predominantly neutrophils, and eosinophilic spongiosis, or both. Eighteen of 32 patients showed positive deposition of linear-granular IgG or complement 3 alone or in various combinations, and five of 24 patients revealed circulating IgG. All the 40 cases with therapeutic details were cured by antiscabietic remedy. BS always involves the trunk and extremities. It has a predilection for elderlies and males. The treatments for BS are similar to those of classical scabies. PMID:27402514

    Full Text Available Background: The in situ signaling transduction within skin biopsies from patients affected by autoimmune skin blistering diseases is not well-characterized. Aim : In autoimmune skin blistering diseases, autoantibodies seem to trigger several intracellular signaling pathways and we investigated the presence of the phosphorylated form of ribosomal protein S6-pS240 within autoimmune skin blistering diseases biopsies. Materials and Methods: We utilized immunohistochemistry to evaluate the presence of S6-pS240 in lesional skin biopsies of patients affected by autoimmune skin blistering diseases including patients with an endemic and nonendemic pemphigus foliaceus (non EPF, with bullous pemphigoid (BP, pemphigus vulgaris (PV, dermatitis herpetiformis (DH, and the respective controls. Results: Most autoimmune bullous skin diseases biopsies stained positive for S6-pS240 around lesional blisters, including adjacent areas of the epidermis; and within upper dermal inflammatory infiltrates, and/or mesenchymal-endothelial cell junctions within the dermis. Conclusions: We document that S6-pS240 is expressed in lesional areas of skin biopsies from patients with autoimmune skin blistering diseases, as well as on eccrine glands and piloerector muscles. Thus, the role of this molecule in autoimmune skin blistering diseases warrants further study.

    2014-04-01

    Full Text Available Introduction: Human genes responsible for human antigen presentation and transplant rejection functions are located on the short arm of Chromosome 6 and are called the Major Histocompatibility Complex (MHC. Moreover, the primary physiologic function of MHC molecules is to present peptides to T lymphocytes. MHC molecules are integral components of the ligands that most T cells recognize, since the T cell receptor (TCR has specificity for complexes of foreign antigenic peptides, as well as self-MHC molecules. Aim: Our investigation attempts to investigate the presence of HLA-DPDQDR within lesional skin biopsies from patients affected by autoimmune skin blistering diseases (ABDs. Materials and Methods: We utilized immunohistochemistry (IHC to evaluate the presence of HLA-DPDQDR in lesional skin biopsies of patients affected by ABDs. We tested 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the EPF endemic area, and 15 biopsies from healthy controls from the USA. We also tested archival biopsies from patients with selected ABDs, including 30 patients with bullous pemphigoid (BP, 20 with pemphigus vulgaris (PV, 8 with pemphigus foliaceus (PF, 14 with dermatitis herpetiformis (DH and 2 with epidermolysis bullosa acquisita (EBA. Results: Most ABD biopsies stained positive for HLA-DPDQDR in the lesional blisters and/or inflamed neurovascular plexus in the superficial dermis, and also at mesenchymal-endothelial like-cell junctions in the dermis. In BP, EBA and EPF, the HLA-DPDQDR staining was also seen in the dermal eccrine sweat gland coils and and ducts. Conclusion: Here, we document that HLA-DPDQDR is expressed in several anatomic areas of lesional skin in patients with ABDs. Notably, HLA-DPDQDR positivity was also consistently present in areas of the classic immune response in pemphigus epidermal keratinocytic intercellular junctions, and at basement membrane sites in bullous pemphigoid and other subepidermal blistering diseases.

    2014-01-01

    Full Text Available Introduction: Bullous systemic lupus erythematosus (BSLE is an autoantibody-mediated disease with subepidermal blisters. It is a rare form of presentation of SLE that occurs in less than 5% of cases of lupus. Case Report: A 27-year-old, female, FRS patient reported the appearance of painful bullous lesions in the left nasal wing and left buccal mucosa that displayed sudden and rapid growth. She sought advice from emergency dermatology staff 15 days after onset and was hospitalized with suspected bullous disease. Intravenous antibiotics and steroids were administered initially, but the patient showed no improvement during hospitalization. She displayed further extensive injuries to the trunk, axillae, and vulva as well as disruption of the bullous lesions, which remained as hyperemic scars. Incisional biopsy of a lesion in the left buccal mucosa was performed, and pathological results indicated mucositis with extensive erosion and the presence of a predominantly neutrophilic infiltrate with degeneration of basal cells and apoptotic keratinocytes. Under direct immunofluorescence, the skin showed anti-IgA, anti-IgM, and anti-IgG linear fluorescence on the continuous dermal side of the cleavage. Indirect immunofluorescence of the skin showed conjugated anti-IgA, was anti-IgM negative, and displayed pemphigus in conjunction with anti-IgG fluorescence in the nucleus of keratinocytes, consistent with a diagnosis of bullous lupus erythematosus. Discussion: BSLE is an acquired autoimmune bullous disease caused by autoantibodies against type VII collagen or other components of the junctional zone, epidermis, and dermis. It must be differentiated from the secondary bubbles and vacuolar degeneration of the basement membrane that may occur in acute and subacute cutaneous lupus erythematosus.

    Full Text Available Bullous SLE has a distinctive clinical, histopathologic and immunopathologic features that together constitute a unique bullous disease phenotype. We report a 33 year old female presenting with multiple tense vesicles and bullae on normal and erythematous skin over the body and oral erosions. Palms and extremities showed typical target lesions. She had consumed NSAIDs intermittently for joint pains. She was diagnosed as bullous erythema multiforme and started on oral prednisolone but lesions failed to heal. Patient recollected a history of low grade fever and a photosensitive rash in the past. Investigations revealed positive ANA with a peripheral pattern. A skin biopsy of a vesicle showed a subepidemal blisher. Perilesional direct immunofluorescence studies showed a linear deposition of IgG, IgA and fibrin along the basement membrane zone and perivascular deposition of IgG. Lapus band test showed a linear deposition of IgG, C3, IgM and fibrin at BMZ clinching the diagnosis of bullous lupus erythematosus.

    2011-06-01

    Full Text Available Tzanck smear test is a simple, rapid, repeatable, and inexpensive diagnostic method based on the investigation of characteristics of individual cells. For diagnosis of cutaneous diseases, cytology was first used by Arnault Tzanck in 1947. After this date, Tzanck cytology has been used in the diagnosis of various erosive-vesiculobullous, nodular, and tumoral skin lesions. In daily dermatology practice, the most common use areas of cytology are diagnosis of herpetic infections, cutaneous leishmaniasis, leprosy, and autoimmune bullous diseases. The purpose of cytology in autoimmune bullous diseases is to rapidly distinguish pemphigus from subepidermal bullous disease. In this review article, taking and staining methods of cytologic specimen for the diagnosis of autoimmune bullous diseases, and the cytologic findings have been reviewed.

    Erysipelas is a generally benign superficial bacterial skin infection, and its bullous form constitutes a rare and more severe variant. We describe the first and fatal case of "bullous erysipelas-like" septic vasculitis due to Pseudomonas bacteremi. A 69-year-old Chinese man presenting with diarrhea and septic shock initially began to rapidly develop sharply defined erythematous plaques with non-hemorrhagic bullae over his lower limbs. Culture of the aspirate from the bullae was positive for Pseudomonas aeruginosa. This was also consistent with his blood cultures showing Pseudomonas bacteremia. Histology of the skin lesion showed microthrombi and neutrophilic infiltrates in blood vessels with Gram-negative bacilli extruding from the vessel walls, characteristic of septic vasculitis. The bullous erysipelas-like lesions seen in this patient represents a rare manifestation of both septic vasculitis and Pseudomonas infection. PMID:26955132

    Full Text Available Multiple myeloma is a malignant plasma cell proliferative disorder that produces a monoclonal immunoglobulin protein. The skin involvement and the development of bullous disease are rarely seen features in multiple myeloma. We present a 55-year-old man with a longstanding, large, tense bullous eruption and hypertrophic scars over his body accompanied recently with weight loss and fatique. He had no response to the previous treatments, which included oral glucocorticoids and dapsone. Histologic examination of the lesions revealed subepidermal bullae, while no immunoflourescence staining was observed. In a further detailed labarotory examination, multiple myeloma was detected. After the treatment of multiple myeloma with chemotherapy, the lesions regressed. Patients with longstanding, recurrent, unusual bullous eruption should be investigated for the development of multiple myeloma.

    International Nuclear Information System (INIS)

    Electron beam therapy applied to a lymph node metastasis from a squamous cell carcinoma was followed by the development of histologically and immunologically typical bullous pemphigoid, the lesions being initially strictly confined to the irradiation area. This observation suggests that the bullous pemphigoid antigen may be altered or unmasked by electron beam radiotherapy, leading subsequently to the production of autoantibodies. The disease in this case effectively responded to the administration of tetracycline and niacinamide, a therapeutic regimen described recently

    Bullous leukemia cutis is an uncommon clinical manifestation of cutaneous infiltration by leukemic cells, from B-cell chronic lymphocytic leukemia. We present the case of a 67-year-old, female, chronic lymphocytic leukemia patient. She was taking chlorambucil and developed facial edema with erythema and warmth, misjudged as facial cellulitis. Two days later, she developed bullous lesions in the arms, legs, neck and face. The histopathology of facial and bullous lesions confirmed leukemia cutis. All lesions disappeared following the administration of rituximab combined with cycles of fludarabine and cyclophosphamide. Although soft tissue infections are common complications in patients undergoing chemotherapy, leukemia cutis can also resemble cellulitis. PMID:27192532

    Full Text Available Non-bullous congenital ichthyosiform erythroderma (NBCIE is a hereditary disorder of keratinization caused by pathogenic variants in genes encoding enzymes important to lipid processing and terminal keratinocyte differentiation. Impaired function of these enzymes can cause pathologic epidermal scaling, significantly reduced skin barrier function. In this study, we have performed a focused, genetic analysis of a probrand affected by NBCIE and extended this to his consanguineous parents. Targeted capture and next-generation sequencing was performed on NBCIE associated genes in the proband and his unaffected consanguineous parents. We identified a homozygous nonsense variant c.814C>T (p.Arg272* in ALOXE3 (NM_001165960.1 in the proband and discovered that his parents are both heterozygous carriers of the variant. The clinical manifestations of the proband’s skin were consistent with NBCIE, and detailed histopathological assessment revealed epidermal bulla formation and Majocchi’s granuloma. Infection with Trichophyton rubrum was confirmed by culture. The patient responded to oral terbinafine antifungal treatment. Decreased skin barrier function, such as that caused by hereditary disorders of keratinization, can increase the risk of severe cutaneous fungal infections and the formation of Majocchi’s granuloma and associated alopecia. Patients with NBCIE should be alerted to the possible predisposition for developing dermatophytoses and warrant close clinical follow-up.

    Full Text Available Bullous pemphigoid (BP is an autoimmune sub-epidermal blistering disorder of the skin. The association of BP with internal malignancy has always been a matter of debate with no consensus reached despite many published case reports and clinical trials. However, we report a hitherto unreported association of BP with squamous cell carcinoma of the tongue, wherein the patient had a recalcitrant downhill course despite adequate treatment measures with control of skin lesions being achieved only following excision of the tumor, and relapse coinciding with detection of metastasis. Hence, given the clinical behavior, it is reasonable to speculate that the association of malignancy was more than co-incidental.

    Full Text Available Background: The chronic use of immunosuppressants in renal transplant recipients (RTRs predisposes them to a variety of skin manifestations. Studies on skin lesions in RTRs from India have been limited. Aim: To study the prevalence and clinical spectrum of skin diseases in RTR in patients attending the Nephrology clinic of a tertiary care hospital in South India. Methods: Between October 2002 and June 2003, 365 RTRs were evaluated for skin lesions, including 280 examined after renal transplant (group A and 85 examined once before and then monthly after transplant for a period of 6 months (group B. Results: A total of 1163 skin lesions were examined in 346 RTRs (94.7% including lesions of aesthetic interest (LAI [62.3%] followed by infections [27.3%]. All LAI were drug-related manifestations, making it the most common skin lesion, while fungal (58.7% and viral (29.3% infections constituted majority of lesions caused by infection. Lesions related to neoplasms were relatively uncommon (2.1% and all lesions were benign. Miscellaneous lesions constituted 8.3% of skin lesions, which included vaccine-induced necrobiotic granulomas at the site of Hepatitis B vaccination and acquired perforating dermatoses. Conclusion: Skin lesions among RTRs from India consist predominantly of drug-related LAI and infections and are different from the West in view of the paucity of neoplastic lesions.

    The history of medicine is replete with examples of debunked myths, and in daily clinical dermatological practice, we must still counter many misconceptions regarding pigmented lesions, both with patients and other medical practitioners. Debunking myths and attempting to explain the reasons for these erroneous beliefs are the purposes of this review. The literature review has been partially guided by the results obtained from an online questionnaire conducted on an Italian website (www.vediamocichiara.it) from February 15, 2015 to March 15, 2015. The remaining discussed were selected on the basis of the existing literature and our personal experience. In order to explore these misconceptions, the following are the seven most salient questions that require investigation: (i) Is it dangerous to excise moles?; (ii) Is it dangerous to traumatize moles?; (iii) Are plantar moles worrisome?; (iv) Is it necessary to selectively apply sunscreen to moles?; (v) Is it inadvisable to partially biopsy a melanoma?; (vi) Do moles turn into melanoma?; and (vii) Is it necessary to perform sentinel lymph node biopsy for thin melanomas and for atypical Spitz naevi? Myths are ubiquitous, being prevalent in dermatological practice, with many of them concerning pigmented skin lesions. By encouraging critical analysis by patients and medical practitioners, the birth and perpetuation of myths can potentially be minimized, for the ultimate benefit of patients. This requires a scientific approach to be rigorously applied to dermatology, with critical questioning of unsubstantiated hypotheses including those emanating from the mass media as well as from respected sources.

    Full Text Available Introduction: The in situ immune response within skin biopsies from patients affected by autoimmune skin blistering diseases (ABDs is not well characterized. Aim: Based on the fact that the ABD immune response is considered an adaptive immune response, both an innate immune response and inflammation would be expected in these diseases. Our investigation investigates the presence of cyclo-oxygenase-2 (COX-2, since this enzyme is commonly involved in innate immune responses. Methods: We utilized immunohistochemistry (IHC to evaluate the presence of COX-2 in lesional skin biopsies of patients affected by ABDs. We tested 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the endemic area, and 15 biopsies from healthy controls from the USA. We also tested archival biopsies from patients with selected ABDs, including 20 patients with bullous pemphigoid, 20 with pemphigus vulgaris, 8 with pemphigus foliaceus and 12 with dermatitis herpetiformis. Results: Most ABD biopsies stained positive for COX-2 in the lesional blister and/or the dermal inflammatory infiltrate, accentuated in the upper neurovascular plexus. In BP and EPF, the COX-2 staining was also seen in the sweat glands. All controls were negative. Conclusions: We document that COX-2 is expressed in lesional skin of patients with ABDs.

    Full Text Available Abstract Background Various antigen-specific immunoassays are available for the serological diagnosis of autoimmune bullous diseases. However, a spectrum of different tissue-based and monovalent antigen-specific assays is required to establish the diagnosis. BIOCHIP mosaics consisting of different antigen substrates allow polyvalent immunofluorescence (IF tests and provide antibody profiles in a single incubation. Methods Slides for indirect IF were prepared, containing BIOCHIPS with the following test substrates in each reaction field: monkey esophagus, primate salt-split skin, antigen dots of tetrameric BP180-NC16A as well as desmoglein 1-, desmoglein 3-, and BP230gC-expressing human HEK293 cells. This BIOCHIP mosaic was probed using a large panel of sera from patients with pemphigus vulgaris (PV, n = 65, pemphigus foliaceus (PF, n = 50, bullous pemphigoid (BP, n = 42, and non-inflammatory skin diseases (n = 97 as well as from healthy blood donors (n = 100. Furthermore, to evaluate the usability in routine diagnostics, 454 consecutive sera from patients with suspected immunobullous disorders were prospectively analyzed in parallel using a the IF BIOCHIP mosaic and b a panel of single antibody assays as commonly used by specialized centers. Results Using the BIOCHIP mosaic, sensitivities of the desmoglein 1-, desmoglein 3-, and NC16A-specific substrates were 90%, 98.5% and 100%, respectively. BP230 was recognized by 54% of the BP sera. Specificities ranged from 98.2% to 100% for all substrates. In the prospective study, a high agreement was found between the results obtained by the BIOCHIP mosaic and the single test panel for the diagnosis of BP, PV, PF, and sera without serum autoantibodies (Cohen’s κ between 0.88 and 0.97. Conclusions The BIOCHIP mosaic contains sensitive and specific substrates for the indirect IF diagnosis of BP, PF, and PV. Its diagnostic accuracy is comparable with the conventional multi

    Developing automatic diagnostic tools for the early detection of skin cancer lesions in dermoscopic images can help to reduce melanoma-induced mortality. Image segmentation is a key step in the automated skin lesion diagnosis pipeline. In this paper, a fast and fully-automatic algorithm for skin lesion segmentation in dermoscopic images is presented. Delaunay Triangulation is used to extract a binary mask of the lesion region, without the need of any training stage. A quantitative experimental evaluation has been conducted on a publicly available database, by taking into account six well-known state-of-the-art segmentation methods for comparison. The results of the experimental analysis demonstrate that the proposed approach is highly accurate when dealing with benign lesions, while the segmentation accuracy significantly decreases when melanoma images are processed. This behavior led us to consider geometrical and color features extracted from the binary masks generated by our algorithm for classification, achieving promising results for melanoma detection.

    In dermatology, various digital imaging modalities have been used as an important tool to quantitatively evaluate the treatment effect of skin lesions. Cross-polarization color image was used to evaluate skin chromophores (melanin and hemoglobin) information and parallel-polarization image to evaluate skin texture information. In addition, UV-A induced fluorescent image has been widely used to evaluate various skin conditions such as sebum, keratosis, sun damages, and vitiligo. In order to maximize the evaluation efficacy of various skin lesions, it is necessary to integrate various imaging modalities into an imaging system. In this study, we propose a multimodal digital color imaging system, which provides four different digital color images of standard color image, parallel and cross-polarization color image, and UV-A induced fluorescent color image. Herein, we describe the imaging system and present the examples of image analysis. By analyzing the color information and morphological features of facial skin lesions, we are able to comparably and simultaneously evaluate various skin lesions. In conclusion, we are sure that the multimodal color imaging system can be utilized as an important assistant tool in dermatology.

  7. Automated segmentation of pigmented skin lesions in multispectral imaging

    International Nuclear Information System (INIS)

    The aim of this study was to develop an algorithm for the automatic segmentation of multispectral images of pigmented skin lesions. The study involved 1700 patients with 1856 cutaneous pigmented lesions, which were analysed in vivo by a novel spectrophotometric system, before excision. The system is able to acquire a set of 15 different multispectral images at equally spaced wavelengths between 483 and 951 nm. An original segmentation algorithm was developed and applied to the whole set of lesions and was able to automatically contour them all. The obtained lesion boundaries were shown to two expert clinicians, who, independently, rejected 54 of them. The 97.1% contour accuracy indicates that the developed algorithm could be a helpful and effective instrument for the automatic segmentation of skin pigmented lesions. (note)

One hundred patients of dengue fever with positive anti-dengue Immunoglobulin M (IgM) serology were included in the study. The admitted patients in PNS Shifa Hospital, Jinnah Postgraduate Medical Centre (JPMC) and Civil Hospital, Karachi were selected for the study. Presenting features were noted. The patients were physically examined for the presence of skin and mucosal lesions and findings were recorded. Total and Differential Leukocyte Count (TLC and DLC), platelet count and Liver Function Tests (LFTs) were done in all the patients. All the patients had low leukocyte and low platelet counts. The common presenting symptoms were high-grade fever with or without rigors, headache, body aches, backache, vomiting, sore throat with cough and generalized weakness (seen in 86% patients). The uncommon presenting features were diarrhea, abdominal pain, bleeding from gums and nosebleeds (seen in 14% patients). Sixty-eight (68%) patients had skin lesions. The most common skin presentation was generalized macular blanchable erythema involving trunk and limbs, seen in 44 (65%) cases. Discrete petechial lesions were seen on various body areas in 24 (35%) cases. Palmer erythema was seen in 20 (30%) patients. Generalized itching was seen in 16 (23%) cases. Isolated itching of palms and soles was seen in 20 (30%) cases. Twenty-eight (28%) patients had deranged LFTs. Out of those, 4 patients had raised serum bilirubin level whereas rest of the 24 had raised ALT. Dengue fever commonly presents with specific skin lesions.

    Full Text Available Background: Previous reports have shown that indirect immunofluorescence (IIF performed on sodium chloride-split skin (SSS is helpful to differentiate epidermolysis bullosa acquisita (EBA from bullous pemphigoid (BP. Antibodies of BP may bind to the epidermal side of SSS, while antibodies of EBA bind to the dermal side. Aims: To determine the accuracy of IIF-SSS in the differential diagnosis of EBA and BP utilizing immunoblotting (IB analysis. Methods: Sera from 78 patients, diagnosed with BP by clinical features, histopathology, and direct immunofluorescence (DIF, were assayed using IIF-SSS and IB. Results: Of the 43 serum samples with an epidermal reaction to IIF-SSS assay, 42 were recognized with BP antigens (180 kDa or 230 kDa. Of the 11 serum samples with a dermal reaction pattern, 7 were recognized with the 290 kDa antigen of EBA and 3 with sera bound BP antigens. Seven serum samples with epidermal and dermal combined staining, of which 5 of them reacted with BP antigens, 1 reacted with both BP and EBA antigens. One serum sample from each group showed a negative result by IB. Approximately 9.0% (7/78 of patients diagnosed with BP using regular methods were actually EBA. Conclusions: Epidermal reaction using the IIF-SSS assay highly correlated with the diagnosis of BP. However, dermal reactions correlated poorly with EBA, with some serum samples from BP patients binding to dermal-side antigens. In both epidermal and dermal stained sera using IIF-SSS, there was a possibility of BP and EBA. Differential diagnosis should be confirmed using IB, especially in cases of dermal and double staining patterns assayed using IIF-SSS.

    1996-09-01

    Malignant melanoma is the most common cancer in people less than 35 years of age and incident rates are increasing by approximately 5 percent per annum in many white populations, including British Columbia, Canada. In 1994, a clinical study has been established to digitize melanocytic lesions under a controlled environment. Lesions are digitized from patients who are referred to the Colored Pigment Lesion Clinic in the University of British Columbia. In this paper, we investigate how to use fractal dimensions (FDs) in measuring the irregularity of a skin lesion. In a previous project, we have experimented with 6 different methods to calculate fractal dimensions on a small number of images of skin lesions, and the simple box-counting method performed the best. However, the method did not exploit the intensity information of the images. With the new set of images which are digitized under the controlled environment, we utilize the differential box counting method to exploit such information. Four FD measures, including the direct FD, the horizontal and the vertical smoothing FDs, and the multi- fractal dimension of order two, are calculated based on the original color images. In addition, these 4 FD features are repeatedly calculate for the blue band of the images. This paper reports the different features through the calculations of the fractal dimensions and compares their differentiation power in the use of diagnosis of images of skin lesions.

    Full Text Available Purpose: To report a first case of bullous pemphigoid (BP following intravenous fluorescein for fundus angiography. Clinical Features: A 70-year-old male patient was admitted to the intensive care unit with BP and sepsis. He reported a history of fundus fluorescein angiography with a pre-diagnosis of senile macular degeneration 2 months prior to presentation. At that time, fluorescein extravasated at the antecubital region. Following the procedure, pruritus and erythema began at the wrists bilaterally, and quickly spread to the entire body. The patient also reported a history of allergy to human albumin solution (Plamasteril®; Abbott 15 years before, during bypass surgery. On dermatologic examination, erythematous patches were present on the scalp, chest and anogenital region. Vesicles and bullous lesions were present on upper and lower extremities. On day 2 of hospitalization, tense bullae appeared on the upper and lower extremities. The patient was treated with oral methylprednisolone 48 mg (Prednol®; Mustafa Nevzat, topical clobetasol dipropionate 0.05% cream (Dermovate®; Glaxo SmithKline, and topical 4% urea lotion (Excipial Lipo®; Orva for presumptive bullous pemphigoid. Skin punch biopsy provided tissue for histopathology, direct immunofluorescence examination, and salt extraction, which were all consistent with BP. After 1 month, the patient was transferred to the intensive care unit with sepsis secondary to urinary tract infection; he died 2 weeks later from sepsis and cardiac failure. Conclusions: To our knowledge, this is the first reported case of BP following fundus fluorescein angiography in a patient with known human albumin solution allergy. Consideration should be made to avoid fluorescein angiography, change administration route, or premedicate with antihistamines in patients with known human albumin solution allergy. The association between fundus fluorescein angiography and BP should be further investigated.

Several types of lichen planus (reticular, atrophic, erosive and bullous) within the oral cavity have been described, among which the reticular and erosive types are the most common types,1,2 while the bullous type is rarely observed.1,3 Bullous lichen planus (BLP) lesions are commonly seen on the buccal mucosa, most frequently at the posterior areas adjacent to the second and third molar teeth. Less common localizations are gingiva and inner aspect of the lips.4 Bullae are generally short lived and leave ulcerated lesions on rupturing.1 The clinical diagnosis of bullous lichen planus is extremely difficult, and pathological examinations may be necessary to establish a definitive diagnosis.5

    Bullous pemphigoid (BP) is an autoimmune skin disorder characterized by subepidermal blisters due to deposit of autoantibody against dermal basement membrane protein. It has been reported that BP can occur after allogeneic hematopoietic stem cell transplantation (HSCT). We describe a patient with BP having autoantibody against BP180 after unrelated-donor HSCT against T lymphoblastic leukemia. The patient was treated with steroid leading to complete resolution of BP, but T lymphoblastic leukemia progressed rapidly after steroid hormone treatment. Given that immunosuppressant may reduce graft-versus-tumor effect, immunomodulatory agents such as nicotinamide and tetracycline, erythromycin, and immunoglobulin may be appropriate as soon as typical blister lesions are seen after HSCT.

    Skin cancer is the most common form of cancer in the United States. Although melanoma accounts for just 11% of all types of skin cancer, it is responsible for most of the deaths, claiming more than 7910 lives annually. Melanoma is visually difficult for clinicians to differentiate from Clark nevus lesions which are benign. The application of pattern recognition techniques to these lesions may be useful as an educational tool for teaching physicians to differentiate lesions, as well as for contributing information about the essential optical characteristics that identify them. Purpose: This study sought to find the most effective features to extract from melanoma, melanoma in situ and Clark nevus lesions, and to find the most effective pattern-classification criteria and algorithms for differentiating those lesions, using the Computer Vision and Image Processing Tools (CVIPtools) software package. Methods: Due to changes in ambient lighting during the photographic process, color differences between images can occur. These differences were minimized by capturing dermoscopic images instead of photographic images. Differences in skin color between patients were minimized via image color normalization, by converting original color images to relative-color images. Relative-color images also helped minimize changes in color that occur due to changes in the photographic and digitization processes. Tumors in the relative-color images were segmented and morphologically filtered. Filtered, relative-color, tumor features were then extracted and various pattern-classification schemes were applied. Results: Experimentation resulted in four useful pattern classification methods, the best of which was an overall classification rate of 100% for melanoma and melanoma in situ (grouped) and 60% for Clark nevus. Conclusion: Melanoma and melanoma in situ have feature parameters and feature values that are similar enough to be considered one class of tumor that significantly differs from

    Full Text Available Recent studies suggest that salt split skin is a more sensitive substrate than intact skin for immunofluorescence diagnosis of bullous pemphigoid. We undertook this study to define the role of salt split technique of immunofluorescence findings in 32 clinical and histopothology confirmed cases of bullous pemphigoid. Both direct and indirect immunofluorescences were performed using normal and split skin. Direct immunofluorescence positivity of 100% was noted with both routine and salt split method. Additional immunoreadont deposition was noted with direct method on split skin in 5 cases. Patterns of fluorescence in the latter were roof (40.60%, floor (9.4% and combined roof and floor (50%. On indirect immunofluorescence, positivity was almost doubled with salt split technique ( 68% as compared to routine method (36%. Thus, salt split technique was equivalent to routine on direct method in positivity with additional immunoreactant deposits noted in some and had double the sensitivity of the indirect method in detecting immunofluorescence in bullous pemphigoid.

    2013-01-01

    Ranaviral disease in amphibians has been studied intensely during the last decade, as associated mass-mortality events are considered to be a global threat to wild animal populations. Several studies have also included other susceptible ectothermic vertebrates (fish and reptiles), but only very few cases of ranavirus infections in lizards have been previously detected. In this study, we focused on clinically suspicious lizards and tested these animals for the presence of ranaviruses. Virological screening of samples from lizards with increased mortality and skin lesions over a course of four years led to the detection of ranaviral infections in seven different groups. Affected species were: brown anoles (Anolis sagrei), Asian glass lizards (Dopasia gracilis), green anoles (Anolis carolinensis), green iguanas (Iguana iguana), and a central bearded dragon (Pogona vitticeps). Purulent to ulcerative-necrotizing dermatitis and hyperkeratosis were diagnosed in pathological examinations. All animals tested positive for the presence of ranavirus by PCR and a part of the major capsid protein (MCP) gene of each virus was sequenced. Three different ranaviruses were isolated in cell culture. The analyzed portions of the MCP gene from each of the five different viruses detected were distinct from one another and were 98.4-100% identical to the corresponding portion of the frog virus 3 (FV3) genome. This is the first description of ranavirus infections in these five lizard species. The similarity in the pathological lesions observed in these different cases indicates that ranaviral infection may be an important differential diagnosis for skin lesions in lizards. PMID:24073785

The unique mode of action by which retapamulin selectively inhibits bacterial protein synthesis differentiates it from other nonpleuromutilin antibacterial agents that target the ribosome or ribosomal factors, minimizing the potential for target-specific cross-resistance with other antibacterial classes in current use. In vitro studies show that retapamulin has high potency against the Gram-positive bacteria (Staphylococcus aureus, Streptococcus pyogenes, and coagulase-negative staphylococci commonly found in skin and skin-structure infections (SSSIs, including S. aureus strains with resistance to agents such as macrolides, fusidic acid, or mupirocin, and other less common organisms associated with SSSIs, anaerobes, and common respiratory tract pathogens. Clinical studies have shown that twice-daily topical retapamulin for 5 days is comparable to 10 days of oral cephalexin in the treatment of secondarily infected traumatic lesions. A 1% concentration of retapamulin ointment has been approved for clinical use as an easily applied treatment with a short, convenient dosing regimen for impetigo. Given the novel mode of action, low potential for cross-resistance with established antibacterial agents, and high in vitro potency against many bacterial pathogens

    Full Text Available Lactoferrin (Lf expression was determined immunohistochemically in 57 formalin-fixed paraffin-embedded bioptic samples obtained from an equal number of patients treated by surgery to remove pigmented skin lesions (nevi = 23; melanoma = 12; vulgaris and seborrhoeic warts = 12; basal cell carcinoma = 10; in addition, 10 specimens of normal skin were studied as control. On 3 ?m thick sections, depigmentation and antigen retrieval procedures were performed. The Lf immunoreactivity was revealed by a rabbit anti-human Lf. Quantification of Lf immunoreactivity was performed using an intensity-distribution (ID score. Melanocytic cells, regardless of their benign or malignant nature, were consistently stained, with no significant differences in the Lf IDscore between melanomas or nevi. A different intensity of Lf immunoreactivity was encountered in superficial portions of warts, exclusively inside squamous epithelial cells arranged in sheets or whorls of keratin. On the contrary, basal cell carcinomas were always unstained, while a slight Lf positivity was found in focal keratinized areas present in two tumours showing baso-squamous differentiation. The Lf immunoreactivity was localized in the cytoplasm and only occasionally in the nucleus. The biological meaning of Lf in these cases of human skin specimens remains unexplained, although it cannot be ruled out that Lf might be involved in the defense system against tumours, or alternatively, may be used by cells requiring iron availability for their turnover. Moreover, the immunohistochemical expression of Lf in melanocytic lesions might be also related to a Lf-melanin interaction. Finally, the involvement of Lf in skin squamous non-neoplastic elements could be related to its role as one of the molecules modulating an unspecific inflammatory or anti-oxidant response.

    Pig skin lesions are common significant welfare issues, and can cause large economic losses, due to culling of severely affected animals or carcass condemnation at slaughter. It was considered that the treponemal bacteria associated with digital dermatitis (DD) lesions in cattle, sheep and goats may have a role in these pig lesions. Specific diagnostic PCR assays for three cultivable DD Treponema phylogroups were used to survey relevant porcine lesion samples. Using these assays, DD treponemes were detected in 88% (22/25), 72% (8/11) and 82% (14/17) of tail, ear and flank lesions, respectively. Mouth swabs from animals kept in enclosures with high prevalence of skin lesions were positive for the DD treponemes, but not in enclosures with low lesion prevalence. Culture of treponemes from skin lesions resulted in pure isolates of all three DD-associated phylogroups. This study shows a strong association of DD treponemes with a range of pig skin lesions.

    Purpose of the studies was to determine incidence and severity of lesions resulting from localized deposition of dose to the skin from small (<0.5 mm) discrete radioactive particles. Hanford mini-swine were exposed to localized doses from 0.2 to over 600 Gy (averaged over 1 cm{sup 2} at 70{mu}m depth) from isotopes having max beta particle energies from about 0.3-3 MeV. Incidence of erythema and scabs (indicating ulceration) were scored routinely for up to 71 days post-irradiation. Responses followed normal probability distributions, and thus, no true threshold could be defined. Ten and 50% incidence rates were deduced using probit analyses. Lowest dose producing 10% incidence was about 1 Gy for exposures to Yb-175 (0.5 MeV max energy) beta particles. Severity of lesions was estimated using diameters and persistence. From preliminary considerations of probability of induction, size, and persistence of acute lesions, a special limit for hot particle exposures in the range of 5-50 Gy may be reasonable, with an action level between about 1 Gy and the limit.

The disease is thought to be inherited in X-linked dominant fashion with heterogeneous mutations of the PORCN gene at Xp11.23 locus. Majority of the cases are sporadic, mainly due to postzygotic somatic mutations. The clinical spectrum includes characteristic cutaneous manifestations, multiple skeletal anomalies, and involvement of the eyes, hair, nails, kidneys, and so on. Considerable variability is noted in the clinical expression of the disease probably due to genomic mosaicism. Around 300 cases of Goltz syndrome have been reported in the literature. Here, we report such a case with characteristic skin lesions, multiple bony defects, distinctive facial features, coloboma of iris, and bilateral hydronephrosis. The diagnosis was evident immediately after birth due to the characteristic clinical picture of the baby.

  20. Drinking Water Arsenic Contamination, Skin Lesions, and Malignancies: A Systematic Review of the Global Evidence

    2015-01-01

    Skin lesions and cancer are known manifestations of chronic exposure to arsenic contaminated drinking water. Epidemiologic data primarily comes from regions with exposures 1–2 orders of magnitude above the current World Health Organization (WHO)’s guidelines of 10 μg/L. Emerging evidence indicates that more common exposures may also be related to both non-cancerous and cancerous changes to the skin. In this review, we focus on the body of epidemiologic literature that encompasses exposures within the WHO guidelines, excluding studies that lacked individual exposure estimates and case reports. For skin lesions and skin cancers, 15 and 10 studies were identified that met our criteria, respectively. For skin lesions, a consistent dose-response relationship with water arsenic has been observed, with increased risk evident at low- to moderate-dose exposure. Of the larger studies of specific histologic types of skin cancers, although with differing exposure definitions, there was evidence of dose-related relationships with both basal cell carcinomas and squamous cell carcinomas. The effect of arsenic exposure on skin lesion risk is likely modified by genetic variants that influence arsenic metabolism. Accumulating evidence suggests that arsenic may increase risk of skin lesions and skin cancers at levels not previously considered harmful, and that genetic factors may influence risk. PMID:26231242

  1. Plasmacytoid dendritic cells in skin lesions of classic Kaposi's sarcoma.

    2016-09-01

    Plasmacytoid dendritic cells (pDCs) are the most potent producers of type I interferons (IFNs), which allows them to provide anti-viral resistance and to link the innate and adaptive immunity by controlling the function of myeloid DCs, lymphocytes, and natural killer cells. pDCs are involved in the pathogenesis of several infectious [especially viral, such as Molluscum contagiosum (MC)], inflammatory/autoimmune, and neoplastic entities. Kaposi's sarcoma (KS) is a multifocal, systemic lympho-angioproliferative tumor associated with Kaposi's sarcoma-associated herpesvirus (KSHV) infection. Microscopy typically exhibits a chronic inflammatory lymphoplasmacytic infiltrate in addition to the vascular changes and spindle cell proliferation. Despite the extensive research done on the immune evasion strategies employed by KSHV, pDCs role in relation to KS has only rarely been investigated. Given this, we intend to investigate pDC occurrence and activity in the skin lesions of KS. Immunohistochemical staining for BDCA-2 (specific pDC marker) and MxA (surrogate marker for local type I IFN production) was performed on classic KS (n = 20) with the control group comprising inflamed MC (n = 20). As expected, BDCA-2+ pDCs were present in abundance with diffuse and intense MxA expression (indicative of local type I IFN production) in all inflamed MC cases (20 of 20, 100 %). Though present in all the KS cases, pDCs were significantly less abundant in KS than in inflamed MC cases, and MxA expression was patchy/weak in most KS cases. In summary, pDCs are part of the inflammatory host response in KS; however, they were generally low in number with decreased type I IFN production which is probably related to KSHV's ability to evade the immune system through the production of different viral proteins capable of suppressing IFN production as well as pDC function.

    Full Text Available Background and Design: Bullous disorders are a group of disorders caused by specific antibodies against tissue adhesion molecules in skin and mucosa or genetic inheritance. There are limited detailed epidemiological studies about bullous disorders in Turkey. In this study we evaluated the demographic, clinical, immunopathologic, course and follow-up properties, cases in Konya. Most of cases were in pemphigus and bullous pemphigoid group, so we gave more information about them. Materials and Methods: Ninty three cases that are followed up during the period of 2006-2012 were included in our study. Results: Female cases were %53,8, male cases were %46,2. The mean age was 52,9. In all of cases; %37,6 cases were pemhigus vulgaris, % 34,4 bullous pemphigoid, %15 herediter epidermolysis bullosa, %4,3 were dermatitis herpetiformis, %4,3 were pemphigus foliaceus, %2,2 pemphigus vegetans, %1,1 Hailey- Hailey disease, %1,1 cicatricial pemphigoid. Mean age of Pemhigus vulgaris onset was 45,9 year and mostly it was observed in females. Pemhigus vulgaris has been started at oral mucosae and the time for diagnosis of pemhigus vulgaris, which began at oral mucosae, was longer than other geogrophic regions. Mean age bullous pemphigoid onset was 70 year and mostly it was observed in females. In % 12,5 of cases disease started at oral mucosae. None of the cases had additional autoimmune disorder. We have treated 25 cases with systemic corticosteriods, 41 cases with systemic corticosteriods and adjuvan agents, 11 cases with only one of adjuvan agents, 16 cases with only local streoids. Conclusions: We report the demographic, clinical, immunopathologic, course and follow-up properties of the bullous disorders in Konya.

    Full Text Available Introduction: Previous research on autoimmune skin blistering diseases (ABD has primarily focused on the humoral immune response; moreover, little attention has been given to the potential role of the antigen presenting cells (APCs in lesional skin. Aim: The purpose of our study was to immunophenotype selected APC in the lesional skin of ABDs, utilizing immunohistochemistry (IHC stains. Materials and Methods: We utilized IHC to stain for dendritic cells (DC, staining with CD1a, CD68, HAM56, and S-100 in lesional skin from 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the EPF endemic area, and 15 healthy controls from the USA. We also tested archival biopsies from patients with selected ABD, including 30 patients with bullous pemphigoid (BP, 20 with pemphigus vulgaris (PV, 8 with pemphigus foliaceus (PF and 14 with dermatitis herpetiformis (DH and 2 with epidermolysis bullosa acquisita (EBA. Results: Cells stained by CD68, HAM56 and S-100 were present in the majority of the ABD skin biopsies; these cells were located primarily in perivascular infiltrates surrounding dermal vessels subjacent to the blisters. However, these cells were also noted within the blisters, in vessels supplying dermal eccrine glands and ducts, and in areas of dermal endothelial-mesenchymal cell junction-like structures, especially in BP cases. In our CD1a staining, the number and location of positive staining cells varied with each disease, being abundant in most ABD in the epidermis suprajacent to the blisters, or in the epidermis surrounding the blister site if the blister site epidermis was missing. In the control biopsies, most did not display positive IHC staining, with the exception of a few CD1a positive cells in the epidermis Conclusion: Our findings confirm positive IHC staining for APCs in areas of the skin besides the disease blisters. Our findings suggest that the antigen presentation in ABD proceeds in areas distant from the blister site

    The mechanism of action of pimecrolimus (PIM) on atopic lesions is still under consideration. Thus far, we have evidence of its anti-inflammatory and immunomodulatory activity, and recent papers focus on its effect on epidermal barrier function. This study analysed changes in the expression of genes associated with skin barrier dysfunction in atopic dermatitis (AD) skin lesions after 2 weeks of exposure to PIM 1% cream. A real-time quantitative PCR analysis of selected epidermal differentiation complex genes and three alternative pathway keratins was performed in skin biopsies from 11 individuals with AD before and after PIM exposure. The real-time quantitative PCR analysis was compared to non-lesional skin in the same patients. Involucrin, a small proline-rich region (SPRR) 2C gene, and alternative pathway keratin 16 showed significant over-expression in lesional skin followed by significant decrease after PIM therapy. The SPRR1A gene, S100A9, and keratin 6A were also increased; however, the decrease after PIM treatment was not significant. The changes in S100 A2, A7 and A8 followed a similar course with borderline significance. SPRR4 had a significant decrease in expression in lesional versus non-lesional skin, which persisted after PIM treatment. No significant changes were detected in mRNA expression levels of filaggrin and loricrin. Our results suggest that PIM can be effective in restoring the epidermal barrier in patients with AD at least in part by its impact on expression of genes, which are important for the normal barrier function of skin.

    Pemphigus vulgaris (PV) is a rare, potentially life threatening, autoimmune blistering skin disease. The International Pemphigus and Pemphigoid Foundation (IPPF) has recently developed a disease registry with the aim to enhance our understanding of autoimmune bullous diseases with the long-term goal of acquiring information to improve patient care. Patients were recruited to the IPPF disease registry through direct mail, e-mail, advertisements, and articles in the IPPF-quarterly, -website, -Facebook webpage, and IPPF Peer Health Coaches to complete a 38-question survey. We present here the initial analysis of detailed clinical information collected on 393 PV patients. We report previously unrecognized gender differences in terms of lesion location, autoimmune comorbidity, and delay in diagnosis. The IPPF disease registry serves as a useful resource and guide for future clinical investigation. PMID:24691863

    Full Text Available Abstract Background Polymorphisms in GSTT1, GSTM1 and GSTP1 impact detoxification of carcinogens by GSTs and have been reported to increase susceptibility to environmentally related health outcomes. Individual factors in arsenic biotransformation may influence disease susceptibility. GST activity is involved in the metabolism of endogenous and exogenous compounds, including catalyzing the formation of arsenic-GSH conjugates. Methods We investigated whether polymorphisms in GSTT1, GSTP1 and GSTM1 were associated with risk of skin lesions and whether these polymorphisms modify the relationship between drinking water arsenic exposure and skin lesions in a case control study of 1200 subjects frequency matched on age and gender in community clinics in Pabna, Bangladesh in 2001–2002. Results and discussion GSTT1 homozygous wildtype status was associated with increased odds of skin lesions compared to the null status (OR1.56 95% CI 1.10–2.19. The GSTP1 GG polymorphism was associated with greater odds of skin lesions compared to GSTP1 AA, (OR 1.86 (95%CI 1.15–3.00. No evidence of effect modification by GSTT1, GSTM1 or GSTP1 polymorphisms on the association between arsenic exposure and skin lesions was detected. Conclusion GSTT1 wildtype and GSTP1 GG are associated with increased risk of skin lesions.

    Subepidermal autoimmune bullous diseases (SABD) are some autoimmune skin diseases that can present in a variety of forms and can be a challenging disease to treat. An overview of the different forms of SABD are discussed including bullous pemphigoid (BP), epidermolysis bullosa acquisita (EBA), cicatricial pemphigoid (CP), bullous systemic lupus erythematosus (BSLE), and Anti-p200 pemphigoid. Emphasis on recent advancement is presented. In recent years, improved Knowledge of the mechanisms of intercellular and cell-matrix adhesion has led to better understanding of the blistering process in some SABD. Defects of such structures cause the subepidermal bullous diseases and have also led to the discovery of new diseases (e.g. anti-p200-pemphigoid). Recent studies have outlined the important role of autoantibodies, mast cell lymphocytes and their cytokines in pathogenesis of SABD.

    A 57-year-old woman with mycosis fungoides developed blisters within cutaneous plaques while receiving PUVA therapy and topical nitrogen mustard. Direct and indirect immunofluorescence studies showed the findings of bullous pemphigoid. Her bullous disease was controlled after cessation of these therapies and institution of prednisone and methotrexate. During the 5 months following completion of a course of electron-beam therapy, she has been free of the cutaneous manifestations of both diseases. Previous instances of PUVA-related pemphigoid have occurred in psoriatics. The role of ultraviolet light in the induction of pemphigoid is discussed, particularly with regard to its possible interaction with the altered skin of psoriasis or mycosis fungoides. Some of the rare cases of bullous mycosis fungoides might actually have represented ultraviolet-unmasked bullous pemphigoid.

    Heparin is one of the most widely prescribed medications. Cutaneous reactions distant to the injection site are rare and under-reported in the literature. We present an elderly man with history of CNS lymphoma who underwent treatment of a deep venous thrombosis with enoxaparin and subsequently developed well demarcated bullous lesions within days of heparin initiation. The exact pathophysiology is not well understood. Hemorrhagic bullous dermatosis is a rare cutaneous reaction that is temporally associated with the initiation of heparin products. The handful of cases thus far suggest that regression of these seemingly benign lesions may or may not be associated with dose reduction or discontinuation of heparin products and typically occur within a few weeks. Elderly age appears to be one potential risk factor for development of these rare asymptomatic lesions. Malignancy may have some contributing factor and differentiation between this rare cutaneous manifestation from heparin products and other dermatological findings in patients with malignancy is key. Because of the asymptomatic and self-limiting nature of hemorrhagic bullous dermatoses in the setting of heparin product use, we presume that the reported incidence does not reflect true clinical practice.

  13. Spectrophotometric assessment of pigmented skin lesions: methods and feature selection for evaluation of diagnostic performance

    International Nuclear Information System (INIS)

    This study documents the optical reflectance characteristics of pigmented skin lesions and evaluates their potential for improving the differential diagnosis of malignant melanoma from benign pigmented skin lesions. Optical reflectance spectra in the wavelength range 320 - 1100 nm were obtained from 121 lesions already selected by expert dermatologists as suspicious of malignancy. Characteristic differences in spectra from benign and malignant lesions were studied. Feature extraction showed significant differences between lesion groups classified by histology. Seven of the most relevant features were used in the discriminant analysis of reflectance spectra from 15 melanoma and 32 compound naevi which resulted in a sensitivity of 100% and specificity of 84.4% when compared with histology. This simple objective technique appears to perform as well as the expert dermatologist and may improve the diagnostic accuracy of non-specialists such as trainees and GPs. Further prospective clinical study of reflectance spectrophotometry in a larger patient group is now required. (author)

    Full Text Available Abstract There are only few studies about the relationship of skin lesions and the percutaneous uptake of hazardous substances in exposed workers. Several aromatic amines are well known carcinogens for humans and/or animals. This case report emphasizes the relevance of dermal absorption of the aromatic amine ortho-toluidine considering four workers with different skin status (healthy, erythematous and burned skin as well as dishydrotic eczema during the vulcanisation process of rubber products in a components supplier plant for automobile industry. The results of our case report show that dermal absorption of o-toluidine through damaged epidermal barrier is significantly higher than through healthy skin.

    Mayser, P

    2016-09-01

    Based on the technical information that oral terbinafine must be used with caution in patients with pre-existing psoriasis or lupus erythematosus, the literature was summarized. Terbinafine belongs to the drugs able to induce subcutaneous lupus erythematosus (SCLE)-with a relatively high risk. The clinical picture of terbinafine-induced SCLE may be highly variable and can also include erythema exsudativum multiforme-like or bullous lesions. Thus, differentiation of terbinafine-induced Stevens-Johnson syndrome or toxic epidermal necrolysis may be difficult. Therefore, terbinafine should be prescribed with caution in patients who show light sensitivity, arthralgias, positive antinuclear antibodies or have a history of SLE or SCLE. Case reports include wide-spread, but mostly nonlife-threatening courses, which did not require systemic therapy with steroids or antimalarials in every case. Terbinafine is also able to induce or to aggravate psoriasis. The latency period seems to be rather short (psoriasis or psoriatic diathesis. Azole derivatives according to the guidelines may be used as an alternative. PMID:27455869

    Full Text Available Aeromonas hydrophila is one of the most common bacteria associated with the aquatic environment. There are , however, limited data on A. hydrophila infection in crocodilians. The aim of this report is to describe a case of skin lesions and septicaemia associated with A. hydrophila in a Nile crocodile (Crocodylus niloticus. A captive male crocodile in the Zoological Park of Antalya (Turkey was found dead without showing signs of any disease. Gross examination showed brown or red-spotted skin lesions of varying size. These lesions were mostly scattered over the abdomen and occasionally on the tail and feet. At necropsy, numerous white, multifocal and randomly distributed areas were seen on the liver. Gram-stained smears from skin and liver lesions showed Gram-negative bacilli arranged in clusters. Pure cultures of A. hydrophila were recovered from skin, internal organs and blood. Isolates were found to be susceptible to ceftiofur, amoxicillin + clavulanic acid, oxytetracycline, enrofloxacin, danofloxacin, neomycin, gentamicin, and lincomycin + neomycin. A pathogenicity test was performed using this isolate on 4 male 2-year-old New Zealand white rabbits. Local abscesses formed in 2 rabbits injected subcutaneously and the 2 that were injected intraperitoneally died as a result of septicaemia. In conclusion, this report has shown that A. hydrophila may cause skin lesions and even death due to septicaemia in crocodiles.

    Skin lesions of Wild Turkeys ( Meleagris gallopavo ) are a common cause of concern to wildlife biologists and the general public and are a frequent reason for submission to diagnostic laboratories. The purpose of this retrospective study is to evaluate the causes, occurrence, and epidemiologic patterns of skin lesions in Wild Turkeys in the eastern US. Skin lesions were diagnosed in 30% (n=199) of the 660 Wild Turkey samples submitted to the Southeastern Cooperative Wildlife Disease Study diagnostic service from 1975 to 2013. Avian pox was the most frequent cause of skin lesions (66%, n=131), followed by bacterial dermatitis (22%, n=44), ectoparasitism-related dermatitis (3%, n=6), fungal dermatitis (2.5%, n=5), and neoplasia (2.0%, n=4). Although the gross appearance of skin lesions is often insufficient to determine the etiology, the anatomic distribution of lesions and temporal occurrence of certain diseases may offer insights into likely causes. Cases with lesions involving or restricted to the head and neck were much more likely to be caused by avian pox than other etiologies. Similarly, lesions restricted to the feet were more likely to be of bacterial origin. Skin lesions observed in the fall and winter were more likely to be caused by avian pox, whereas bacterial dermatitis was more frequently observed in the spring and summer. This retrospective study provides a summary of the causes of skin lesions in Wild Turkeys and serves as a useful reference to diagnosticians and biologists when evaluating Wild Turkeys with skin lesions.

    Accurate assessment of acne severity is essential for determining the appropriate treatment required. This paper reviews photographic methods for such assessment. Literature included met the following criteria: proposed photographic standards to assess acne, evaluated such standards, or offered photographic methods to improve visualization and assessment. Validity was evaluated by comparing given photographic grading methods to other methods, such as lesion counting. Many photographic standards were shown to be objective, time-efficient, and have intra-grader and inter-grader consistency. Photography also documents progress for retrospective verification. Drawbacks include not allowing determination of depth, minimization of small lesions and erythema, and difficulty in maintaining consistent settings. Fluorescence and polarized photography improve visualization beyond clinical observation alone. Advances such as computer alignment, imaging segmentation, and three-dimensional analysis methods track lesions and measure objective characteristics. The combined experience summarized here strongly promotes the use of a photographic standard in assessing acne severity. Cook's method can also be used to train and qualify graders. Photographic advancements improve accuracy of assessment by solving problems with consistent settings and depth visualization. Further advancements can improve image analysis through analysis of objective attributes.

    Elevated concentrations of arsenic in groundwater pose a public health threat to millions of people worldwide. The authors aimed to evaluate the association between arsenic exposure and skin lesion incidence among participants in the Health Effects of Arsenic Longitudinal Study (HEALS). The analyses used data on 10,182 adults free of skin lesions at baseline through the third biennial follow-up of the cohort (2000–2009). Discrete-time hazard regression models were used to estimate hazard ratios and 95% confidence intervals for incident skin lesions. Multivariate-adjusted hazard ratios for incident skin lesions comparing 10.1–50.0, 50.1–100.0, 100.1–200.0, and ≥200.1 μg/L with ≤10.0 μg/L of well water arsenic exposure were 1.17 (95% confidence interval (CI): 0.92, 1.49), 1.69 (95% CI: 1.33, 2.14), 1.97 (95% CI: 1.58, 2.46), and 2.98 (95% CI: 2.40, 3.71), respectively (Ptrend = 0.0001). Results were similar for the other measures of arsenic exposure, and the increased risks remained unchanged with changes in exposure in recent years. Dose-dependent associations were more pronounced in females, but the incidence of skin lesions was greater in males and older individuals. Chronic arsenic exposure from drinking water was associated with increased incidence of skin lesions, even at low levels of arsenic exposure (<100 μg/L). PMID:21576319

    Misdiagnosis may result from biopsy site selection, technique, or choice of transport media. Important potential sources of error include false-negative direct immunofluorescence results based on poor site selection, uninformative biopsy specimens based on both site selection and technique, and spurious interpretations of pigmented lesions and nonmelanoma skin cancer based on biopsy technique. Part I of this 2-part continuing medical education article addresses common pitfalls involving site selection and biopsy technique in the diagnosis of bullous diseases, vasculitis, panniculitis, connective tissue diseases, drug eruptions, graft-versus-host disease, staphylococcal scalded skin syndrome, hair disorders, and neoplastic disorders. Understanding these potential pitfalls can result in improved diagnostic yield and patient outcomes.

  1. Visualization of dermal alteration in skin lesions with discoid lupus erythematosus by multiphoton microscopy

    International Nuclear Information System (INIS)

    Discoid lupus erythematosus (DLE) is a chronic dermatological disease which lacks valid methods for early diagnosis and therapeutic monitoring. Considering the collagen and elastin disorder due to mucin deposition of DLE, multiphoton microscopy (MPM) imaging techniques were employed to obtain high-resolution collagen and elastin images from the dermis. The content and distribution of collagen and elastin were quantified to characterize the dermal pathological status of skin lesions with DLE in comparison with normal skin. Our results showed a significant difference between skin lesions with DLE and normal skin in terms of the morphological structure of collagen and elastin in the dermis, demonstrating the possibility of MPM for noninvasively tracking the pathological process of DLE even in its early stages and evaluating the therapeutic efficacy at the molecular level.

    2014-01-01

    Fixed drug eruption (FDE) is an unusual drug-related side effect that results in recurrent lesions whenever the causative drugs are used. FDEs usually occur as a single, sharply demarcated, round erythematous patch or plaque, occasionally with localized bullae. The most common offending agents include antimicrobials, nonsteroidal anti-inflammatory drugs, and antiepileptics. There are some reports where contact dermatitis and cutaneous vasculitis have been associated with the use of flurbiprofen. We present the case of a 50-year-old man with flurbiprofen-induced generalized bullous FDE. To the best of our knowledge, the most serious form of FDE, the generalized bullous FDE, to be caused by flurbiprofen has not been reported previously.

    Autoantibodies to a normal component of stratified squamous epithelia, the bullous pemphigoid antigen (BPA), are synthesized in patients with the disease bullous pemphigoid. We have used these sera to study the distribution of BPA in vivo and in vitro. At low magnification, indirect...... immunofluorescent staining for BPA is linear at the basement membrane zone (BMZ) of skin and many other epithelial tissues. At higher magnification however, we observed a punctate staining pattern for BPA which was regular in appearance and suggested localization of BPA to discrete structures at the BMZ. Subsequent...... immunoelectron microscopy using both peroxidase and colloidal gold labeling techniques with patients' sera or IgG, revealed that BPA is associated with hemidesmosomes--putative adhesion structures at the BMZ, based on their similarity in ultrastructure to desmosomes. More specifically BPA was immunolocalized...

    Full Text Available Venomous animals are those that, by means of a hunting and defense mechanism, are able to inject their prey with a toxic substance produced in their bodies, directly from specialized glands (e.g., tooth, sting, spur through which the poison passes. Millipedes are poisonous animals; they can be harmful to humans, and their effects usually manifest as erythematous, purpuric, and cyanotic lesions; local pain; and paresthesia. Here, we report a case of skin contact with a millipede for 6h resulting in skin lesions similar to blue toe syndrome.

    Canine Malassezia dermatitis is frequently treated with systemic ketoconazole (KTZ) and itraconazole (ITZ). However, no information is available on the antifungal susceptibility to azoles and allilamine of Malassezia pachydermatis isolates from dogs with or without skin lesions. The present study was designed to evaluate the in vitro antifungal susceptibility of M. pachydermatis strains from dogs with or without skin lesions to KTZ, ITZ, miconazole (MICO), fluconazole (FLZ), posaconazole (POS), voriconazole (VOR) and terbinafine (TER) using the Clinical and Laboratory Standards Institute reference Broth Microdilution Method (CLSI M27-A2). The association between the susceptibility to antifungal compounds and the origin of M. pachydermatis, from skin with or without lesions has been also assessed. A total of 62 M. pachydermatis strains from healthy dogs (i.e., Group A=30) or with skin lesions (i.e., Group B=32) were tested. ITZ, KTZ and POS showed the highest activity against M. pachydermatis strains, whereas MICO TER and FLZ the lowest. A higher number of Malassezia resistant strains were registered among isolates from Group B than those from Group A. This study indicates that M. pachydermatis strains were susceptible to ITZ, KTZ, and POS. However, dogs with lesions may harbour strains with low susceptibility to antifungal agents and displaying cross-resistance phenomena to azole. The antifungal therapy in Malassezia infections requires careful appraisal of choice of drugs especially in cases of unresponsiveness to antifungal treatment or recurrent infections. PMID:21962411

    Full Text Available Multiple myeloma, being a malignant proliferation of plasma cells in the bone marrow, has clinical spectrum varying from monoclonal gammopathy with unknown significance to plasma cell leukemia. The presenting symptoms have usually been bone pain, pathologic fractures or repeating infections. In patients with multiple myeloma, amyloid depositions may be seen in the skin. This form, defined as primary systemic amyloidosis, is characterized by light-chain amyloid fibril depositions. Our case applied with multiple, asymptomatic, yellowish papules localized on the face, trunk, oral and genital mucosa, gradually increasing during the last two years. He had no complaints, except for slight weight loss. In routine tests, the patient had no pathological laboratory findings, except high C-reactive protein levels. Further research revealed histopathologic and immunohistochemical findings consistent with amyloidosis. Upon these results, immunoglobulin G levels were measured and found high, and in protein electrophoresis, IgG monoclonal gammopathy was determined. The diagnosis of multiple myeloma is made by bone marrow biopsy. This patient is presented for being an asymptomatic case diagnosed by skin findings of amyloidosis.

    In order to investigate the role of Caspase-3 and Bax in the pathogenesis of lichen planus, immunohistochemistry was used to detect the expression of Caspase-3 and Bax in skin lesions of the patients with lichen planus and skin tissues of normal subjects. The results showed that positive rate of Caspase-3 and Bax expression in lichen planus were significantly higher than that in normal skins (both P<0.05). Meanwhile, there was a obvious correlation between the increase of Caspase-3 and that of Bax in lichen planus. The expression of Caspase-3 and Bax might play an important role in the development of lichen planus.

    A 37-year-old woman with no remarkable medical or family history presented with papules and vesicles on an erythematous background involving the neck, sacrum, and folds (postauricular, axillary, inguinal, and under the breasts) (Figure 1). During the previous year, she was treated with local and systemic antifungals without improvement. Her history included a secondary amenorrhea, polydipsia, and polyuria (6 L/d) that started 2 years prior. Physical examination revealed chronic bilateral purulent otorrhea with thick eardrums. Histologic examination of skin biopsy revealed a highly suggestive appearance of multisystem Langerhans cell histiocytosis (LCH) with immunohistochemistry (anti-PS100 and anti-CD1a), which were positive (Figure 2A and 2B). Pituitary magnetic resonance imaging showed a thickening of the pituitary stalk in relation to a location histiocytic (Figure 3). Bone gaps were objectified on two radiographic tibial diaphyseal. Results from computed tomography (CT) scan showed a magma coelio mesenteric, axillary, and inguinal lymph nodes. PMID:27319965

    Background: Chronic exposure to arsenic is associated with skin lesions. However, it is not known whether reducing arsenic exposure will improve skin lesions. Objective: We evaluated the association between reduced arsenic exposures and skin lesion recovery over time. Methods: A follow-up study of 550 individuals was conducted in 2009–2011 on a baseline population of skin lesion cases (n = 900) previously enrolled in Bangladesh in 2001–2003. Arsenic in drinking water and toenails, and skin lesion status and severity were ascertained at baseline and follow-up. We used logistic regression and generalized estimating equation (GEE) models to evaluate the association between log10-transformed arsenic exposure and skin lesion persistence and severity. Results: During the study period, water arsenic concentrations decreased in this population by 41% overall, and 65 individuals who had skin lesions at baseline had no identifiable lesions at follow-up. In the adjusted models, every log10 decrease in water arsenic and toenail arsenic was associated with 22% [odds ratio (OR) = 1.22; 95% CI: 0.85, 1.78] and 4.5 times (OR = 4.49; 95% CI: 1.94, 11.1) relative increase in skin lesion recovery, respectively. In addition, lower baseline arsenic levels were significantly associated with increased odds of recovery. A log10 decrease in toenail arsenic from baseline to follow-up was also significantly associated with reduced skin lesion severity in cases over time (mean score change of –5.22 units; 95% CI: –8.61, –1.82). Conclusions: Reducing arsenic exposure increased the odds that an individual with skin lesions would recover or show less severe lesions within 10 years. Reducing arsenic exposure must remain a public health priority in Bangladesh and in other regions affected by arsenic-contaminated water. PMID:23060367

    Isolates of the yeast Malassezia pachydermatis obtained from skin samples of healthy dogs and of dogs with atopic dermatitis in Japan, Taiwan and Korea were molecularly characterized using intergenic pacer 1 (IGS1) region analysis. The percentage of IGS1 subtype isolates detected in healthy skin was as follows: 1A (6%), 1B (27%), 1C (11%), 2A (6%), 2B (6%), 3A (11%), 3B (6%), 3C (3%) and 3D (24%). In contrast, the most prevalent isolates detected in skin lesions of atopic dermatitis were subtype 3D in Japan and Taiwan and subtype 3C in Korea. All subtype isolates grew well on acidic medium (pH 6). However, subtype 3C and 3D isolates grew better than the other subtype isolates on medium at pH 8. PMID:23411408

    We evaluated the effect of chitin nanofibril (CNF) application via skin swabs on an experimental atopic dermatitis (AD) model. AD scores were lower, and hypertrophy and hyperkeratosis of the epidermis were suppressed after CNF treatment. Furthermore, inflammatory cell infiltration in both the epidermis and dermis was inhibited. CNFs also attenuated histological scores. The suppressive effects of CNFs were equal to those of corticosteroid application; however, chitin did not show these effects. CNF application might have anti-infllammatory effects via suppression of the activation of nuclear factor-kappa B, cyclooxygenase-2, and inducible nitric oxide synthase. In an early-stage model of experimental AD, CNFs suppressed AD progression to the same extent as corticosteroids. They also suppressed skin inflammation and IgE serum levels. Our findings indicate that CNF application could aid in the prevention or treatment of AD skin lesions. PMID:27112880

    Full Text Available Arsenic is one of the most important toxicants in the environment. In Inner Mongolia of China, 300,000 residents are believed to be drinking water containing >50μg/liter. Skin lesions have been known as the most common consequences resulting from chronic exposure to arsenic. To clarify the prevalence of arsenic-induced skin lesions, it is important to assess the impact of this problem among the target population, and to make future planning. We evaluated the association between multi-levels inorganic arsenic exposure from drinking water and skin lesions in an arsenic-affected area in Inner Mongolia, China. One hundred nine and 32 subjects in high (>50μg/liter and low (150μg/liter were 33.3% (OR =15.50, 95% CI: 1.53-248.70, 46.7% (OR =16.10, 95% CI: 3.73-69.63 and 55.7% (OR= 25.70, 95% CI: 6.43-102.87, respectively. Duration of using well was not associated with increased risk of skin lesions in this population; (OR =1.68, 95% CI: 0.40-6.91 for 6-15 years, OR = 2.30, 95% CI: 0.58-9.14 for over 15 years compared with the duration of less than 5 years.

    Full Text Available A differentiation between all types of melanocytic and non-melanocytic skin lesions (MnM–SK is a challenging task for both computer-aided diagnosis (CAD and dermatologists due to the complex structure of patterns. The dermatologists are widely using pattern analysis as a first step with clinical attributes to recognize all categories of pigmented skin lesions (PSLs. To increase the diagnostic accuracy of CAD systems, a new pattern classification algorithm is proposed to predict skin lesions patterns by integrating the majority voting (MV–SVM scheme with multi-class support vector machine (SVM. The optimal color and texture features are also extracted from each region-of-interest (ROI dermoscopy image and then these normalized features are fed into an MV–SVM classifier to recognize seven classes. The overall system is evaluated using a dataset of 350 dermoscopy images (50 ROIs per class. On average, the sensitivity of 94%, specificity of 84%, 93% of accuracy and area under the receiver operating curve (AUC of 0.94 are achieved by the proposed MnM–SK system compared to state-of-the-art methods. The obtained result indicates that the MnM–SK system is successful for obtaining the high level of diagnostic accuracy. Thus, it can be used as an alternative pattern classification system to differentiate among all types of pigmented skin lesions (PSLs.

    Poxvirus skin disease has been reported in several species of cetaceans, principally in odontocetes, and a single report in mysticetes. Southern right whales Eubalaena australis in Peninsula Valdes, Argentina, show a variety of skin lesions of unknown etiology, and the number of these lesions has increased in recent years. Samples from dead whales were taken in order to establish the etiology of these lesions. One calf and one adult presented ring-type lesions, characterized by a circumscribed and slightly raised area of skin. Lesions were histologically characterized by the presence of microvesicles and vacuolated cells in the stratum spinosum, along with hyperplasia of the stratum corneum and eosinophilic inclusion bodies in the cytoplasm of the epithelial cells. Transmission electron microscopy showed aggregations of virions with typical poxvirus morphology. PCR of cetacean poxvirus (CPV) DNA polymerase, DNA topoisomerase I and parapoxvirus DNA polymerase gene fragments was done, and confirmed the presence of poxvirus in one sample. Phylogenetic analysis showed that the detected poxvirus belongs to the CPV-2 group. This is the first confirmed report of poxvirus in southern right whales in Argentina.

    Full Text Available In vivo reflectance confocal microscopy (RCM is a noninvasive method that allows imaging of cells and structures in living skin with resolution close to the histological analysis. RCM allows the assessment of dynamic events in the epidermis, papillary dermis and superficial reticular dermis. From the stratum corneum to a depth of a maximum of 350 μm can be analysed. The noninvasive feature of this technique, allows repetitive imaging without any damage to the affected area and to evaluate the response to the treatment. RCM, provides great convenience in assesment of normal skin and particularly in the evaluation of melanocytic lesions due to high contrast features of melanin and melanosomes. In this article morphology of normal skin and features of melanocytic lesions is described with RCM.

    Risk of skin lesions due to chronic arsenic exposure can be further affected by nutrient intake. We prospectively evaluated the association of nutrient intake and gender with incident skin lesions using data from the Health Effects of Arsenic Longitudinal Study (HEALS) in Araihazar, Bangladesh. Discrete time hazard models were used to estimate these effects in stratified analyses based on skin lesion severity. Overall, we observed significant associations between low intakes of various nutrients (retinol, calcium, fiber, folate, iron, riboflavin, thiamin, and vitamins A, C, and E) and skin lesion incidence, particularly for keratotic skin lesions. Associations for vitamins C and E showed significant linear trends. Gender-specific analyses revealed an inverse association between the lowest quartile of nutrient intake and keratotic skin lesion incidence for retinol equivalents, calcium, folate, iron, and fiber among women. Interactions by gender were observed for retinol equivalents (P-interaction = 0.03), calcium (P-interaction = 0.04), vitamin A (P-interaction = 0.03), and riboflavin (P-interaction = 0.04) with the incidence of keratotic skin lesions. Understanding differential susceptibility to skin lesion incidence based on nutrient intake will help researchers develop targeted interventions to prevent health consequences of arsenic poisoning in Bangladesh and beyond.

    Full Text Available There is increasing concern for the well-being of cetacean populations around the UK. Tattoo skin disease (characterised by irregular, grey, black or yellowish, stippled cutaneous lesions caused by poxvirus infection is a potential health indicatora potential health indicator for cetaceans. Limited sequence data indicates that cetacean poxviruses (CPVs belong to an unassigned genus of the Chordopoxvirinae. To obtain further insight into the phylogenetic relationships between CPV and other Chordopoxvirinae members we partially characterized viral DNA originating from tattoo lesions collected in Delphinidae and Phocoenidae stranded along the UK coastline in 1998-2008. We also evaluated the presence of CPV in skin lesions other than tattoos to examine specificity and sensitivity of visual diagnosis. After DNA extraction, regions of the DNA polymerase and DNA topoisomerase I genes were amplified by PCR, sequenced and compared with other isolates. The presence of CPV DNA was demonstrated in tattoos from one striped dolphin (Stenella coeruleoalba, eight harbour porpoises (Phocoena phocoena and one short-beaked common dolphin (Delphinus delphis and in one 'dubious tattoo' lesion detected in one other porpoise. Seventeen of the 18 PCR positive skin lesions had been visually identified as tattoos and one as a dubious tattoo. None of the other skin lesions were PCR positive. Thus, visual identification had a 94.4% sensitivity and 100% specificity. The DNA polymerase PCR was most effective in detecting CPV DNA. Limited sequence phylogeny grouped the UK samples within the odontocete poxviruses (CPV group 1 and indicated that two different poxvirus lineages infect the Phocoenidae and the Delphinidae. The phylogenetic tree had three major branches: one with the UK Phocoenidae viruses, one with the Delphinidae isolates and one for the mysticete poxvirus (CPV group 2. This implies a radiation of poxviruses according to the host suborder and the families within

    Localised cutaneous leishmaniasis (LCL) is the most common form of cutaneous leishmaniasis characterised by single or multiple painless chronic ulcers, which commonly presents with secondary bacterial infection. Previous culture-based studies have found staphylococci, streptococci, and opportunistic pathogenic bacteria in LCL lesions, but there have been no comparisons to normal skin. In addition, this approach has strong bias for determining bacterial composition. The present study tested the hypothesis that bacterial communities in LCL lesions differ from those found on healthy skin (HS). Using a high throughput amplicon sequencing approach, which allows for better populational evaluation due to greater depth coverage and the Quantitative Insights Into Microbial Ecology pipeline, we compared the microbiological signature of LCL lesions with that of contralateral HS from the same individuals.Streptococcus, Staphylococcus,Fusobacterium and other strict or facultative anaerobic bacteria composed the LCL microbiome. Aerobic and facultative anaerobic bacteria found in HS, including environmental bacteria, were significantly decreased in LCL lesions (p < 0.01). This paper presents the first comprehensive microbiome identification from LCL lesions with next generation sequence methodology and shows a marked reduction of bacterial diversity in the lesions.

    The association between psoriasis vulgaris and bullous pemphigoid is due to the still unclear autoimmune process. The common disease site is the dermo-epidermal junction or basal membrane zone (BMZ), with specific alterations for both diseases. Photochemotherapy (PUVA) is one of the therapeutic modalities for psoriasis and can trigger production of autoantibodies against antigens in the BMZ in patients with subclinical bullous pemphigoid. Furthermore, PUVA therapy can alter the immunological milieu and hence can contribute to the expression of bullous pemphigoid in patients with psoriasis. We observed a bullous eruption compatible with bullous pemphigoid in a psoriatic patient treated with PUVA. We speculate that the cumulative dose of PUVA sufficient for triggering blister formation is individually determined. PMID:27663923

    Although elasmobranch species are increasingly displayed in public aquaria, knowledge of disease in wild and captive elasmobranchs, as well as the agents involved, remains limited, and descriptions are often incomplete. This report describes papillomatous skin lesions in a juvenile giant guitarfish Rhynchobatus djiddensis associated with intranuclear viral particles. Skin biopsies were collected from multiple, friable, raised, villonodular skin lesions affecting pigmented and non-pigmented skin of the caudal fin and ventrum, respectively. Microscopic examination revealed papillary proliferation of the epidermis, with widespread marked karyomegaly of squamous epithelial cells. In approximately 75% of nuclei, chromatin was marginated by one to multiple, large, amphophilic inclusions. Large numbers of unencapsulated, 75 nm, icosahedral viral particles were observed to form large arrays in affected nuclei using transmission electron microscopy. Based on intranuclear location, particle size and morphology, a consensus nested-PCR for adenovirus polymerase was attempted. However, no adenoviral gene sequence was amplified. The nature of the involved virus remains unknown and an ongoing area of investigation. Lesions regressed completely over a 6 mo period, during which time the animal showed no signs of systemic illness, and there has been no recrudescence for 6 mo following resolution. Two cohorts of similar age and in close contact with the case animal were unaffected.

    Recipients of solid organ transplants (RSOT) have a highly increased risk for developing cutaneous premalignant and malignant lesions, favored by the lifelong immunosuppression. Vascularized composite tissue allografts (VCA) have been introduced recently, and relevant data are sparse. Two patients with skin cancers (one with basal cell carcinoma and one with squamous cell carcinomas) have been so far reported in this patient group. Since 2000 we have been following 9 recipients of VCA (3 face, 6 bilateral hands) for the development of rejection and complications of the immunosuppressive treatment. Among the 9 patients, one face-grafted recipient was diagnosed with nodular-pigmented basal cell carcinoma of her own facial skin 6 years after graft, and one patient with double hand allografts developed disseminated superficial actinic porokeratosis, a potentially premalignant dermatosis, on her skin of the arm and legs. Similar to RSOT, recipients of VCA are prone to develop cutaneous premalignant and malignant lesions. Prevention should be applied through sun-protective measures, regular skin examination, and early treatment of premalignant lesions. PMID:26550517

    Atopic dermatitis (AD) is a chronic inflammatory skin disease with a complex etiology that encompasses immunologic responses. AD is frequently associated with elevated immunoglobulin (Ig) E levels, and common environmental factors contribute to its pathogenesis. Several recent studies have documented the role of specific lactic acid bacteria in the treatment and prevention of AD in humans and mice. In this study, the efficacy of Duolac ATP, a probiotic preparation, was determined in a mouse model with AD-like skin lesions. Alterations in the cytokine levels and histological staining suggested the alleviation of AD. The in vivo test showed that T helper (Th)2 cytokines, IgE, interleukin (IL)-4, and IL-5, were significantly downregulated, whereas Th1 cytokines, IL-12p40 and interferon (IFN)-γ, were upregulated in all groups of mice treated with Duolac ATP compared to that observed in the group of mice treated with 1-chloro-2,4-dinitrobenzene (DNCB) alone. Moreover, the scratch score decreased in all mice treated with Duolac ATP. Staining of the dorsal area of the mice in each group with hematoxylin and eosin and toluidine blue further confirmed the alleviation of AD in mice orally treated with Duolac ATP. These results suggest that Duolac ATP inhibits the development of AD-like skin lesions in NC/Nga mice by suppressing the Th2 cell response and increasing the Th1 cell response. Thus, Duolac ATP is beneficial and effective for the treatment of AD-like skin lesions. PMID:27123166

This study aims to evaluate cytopathology as a quick non-invasive method for early diagnosis of different skin conditions including neoplastic and non-neoplastic. Fine Needle Aspiration Cytology (FNAC is a simple and rapid diagnostic technique. The present study is a retrospective analysis of 356 patients who were cytologically evaluated for various skin and superficial soft tissue lesions over a period of four years (W. E. F. January 2012 to December 2015 in the Department of Dermatology and Pathology of Tripura Medical College and Dr. BRAM Teaching Hospital. Amongst the 356 cases reported, 170 cases were non-neoplastic and 186 were reported as neoplastic skin lesions. Out of 186 neoplastic lesions, 134 (72.04% were benign in nature and rest of the cases were malignant, i.e. only 52 cases (27.95%. Commonest non-neoplastic lesion epidermal inclusion cyst followed by acute suppurative lesions. Other lesions which were commonly reported in our study were Granulomatous lesions. It has been observed that FNAC performed carefully, skilfully with proper selection of cases leads to an early diagnosis in majority of the skin lesions.

    Dermoscopy is a technique used to capture the images of skin, and these images are useful to analyze the different types of skin diseases. Malignant melanoma is a kind of skin cancer whose severity even leads to death. Earlier detection of melanoma prevents death and the clinicians can treat the patients to increase the chances of survival. Only few machine learning algorithms are developed to detect the melanoma using its features. This paper proposes a Computer Aided Diagnosis (CAD) system which equips efficient algorithms to classify and predict the melanoma. Enhancement of the images are done using Contrast Limited Adaptive Histogram Equalization technique (CLAHE) and median filter. A new segmentation algorithm called Normalized Otsu's Segmentation (NOS) is implemented to segment the affected skin lesion from the normal skin, which overcomes the problem of variable illumination. Fifteen features are derived and extracted from the segmented images are fed into the proposed classification techniques like Deep Learning based Neural Networks and Hybrid Adaboost-Support Vector Machine (SVM) algorithms. The proposed system is tested and validated with nearly 992 images (malignant & benign lesions) and it provides a high classification accuracy of 93 %. The proposed CAD system can assist the dermatologists to confirm the decision of the diagnosis and to avoid excisional biopsies.

The proposed system is tested and validated with nearly 992 images (malignant & benign lesions) and it provides a high classification accuracy of 93 %. The proposed CAD system can assist the dermatologists to confirm the decision of the diagnosis and to avoid excisional biopsies. PMID:26872778

    Increasing exposure to UV radiation is considered the most important etiologic factor of nonmelanoma skin cancers. Consequently, exposed areas such as the scalp and face, are the primary areas for developing non-melanoma skin cancers. Once a patient has presented with one tumor, additional lesions are common. The diagnosis is based on typical clinical picture and biopsy or excision for histopathological analysis. Various non-surgical treatment options have been established. Superficial basal cell carcinoma, superficial carcinoma in situ and all actinic keratoses are preferentially treated non-surgically. Most other basal cell and squamous cell carcinomas should be surgically removed. PMID:24724463

    Full Text Available Dermatitis herpetiformis (DH is a rare autoimmune disease linked to gluten sensitivity with a chronic-relapsing course. It is currently considered to be the specific cutaneous manifestation of celiac disease (CD. Both conditions are mediated by the IgA class of autoantibodies, and the diagnosis of DH is dependent on the detection of granular deposits of IgA in the skin. There is an underlying genetic predisposition to the development of DH, but environmental factors are also important. This paper describes these different factors and discusses the known mechanism that lead to the development of skin lesions.

    Full Text Available Ehlers-Danlos syndrome, characterized by hyperextensible skin, hypermobile joints, and fragile vessels, is the most common heritable disorder of connective tissue and has an estimated prevalence of 1 in 5000. Pulmonary involvement with signs of lung destruction (bullous emphysema as first presentation is unusual. We report a case of monozygotic twins 37 years old men with occasional evidence of bullous emphysema with previously undiagnosed Ehlers-Danlos syndrome type IV. We emphasize the importance of considering uncommon genetic causes of emphysema in young adults, discuss underlining pathophysiological mechanisms and propose a conservative management and follow-up.

    Full Text Available The concomitant occurrence of psoriasis and bullous pemphigoid has been described previously, but the pathogenic mechanism of this relationship is still unknown. We describe a 34-year-old woman with a 22-year history of plaque-type psoriasis. On the third day of hospitalization, disseminated tense bullae developed on her neck and upper extremities. Histologic examination of biopsy specimen obtained from a vesicular lesion demonstrated a subepidermal blister. Direct immunofluorescence revealed IgG and C3 deposition in a linear pattern at the basement membrane zone. Both diseases were successfully treated with cyclosporine. However, the coexistence of these conditions represents a difficult therapeutic challenge.

    Background Bullous pemphigoid (BP) is a chronic, autoimmune blistering skin disease that affects patients' daily life and psychosocial well-being. Objective The aim of the study was to evaluate the quality of life, anxiety, depression and loneliness in BP patients. Methods Fifty-seven BP patients and fifty-seven healthy controls were recruited for the study. The quality of life of each patient was assessed using the Dermatology Life Quality Index (DLQI) scale. Moreover, they were evaluated for anxiety and depression according to the Hospital Anxiety Depression Scale (HADS-scale), while loneliness was measured through the Loneliness Scale-Version 3 (UCLA) scale. Results The mean DLQI score was 9.45±3.34. Statistically significant differences on the HADS total scale and in HADS-depression subscale (p=0.015 and p=0.002, respectively) were documented. No statistically significant difference was found between the two groups on the HADS-anxiety subscale. Furthermore, significantly higher scores were recorded on the UCLA Scale compared with healthy volunteers (p=0.003). Conclusion BP had a significant impact on quality of life and the psychological status of patients, probably due to the appearance of unattractive lesions on the skin, functional problems and disease chronicity.

    One of the greatest challenges in dermatology today is the early detection of melanoma since the success rates of curing this type of cancer are very high if detected during the early stages of its development. The main objective of the work presented in this paper is to create a prototype of a patient-oriented system for skin lesion analysis using a smartphone. This work aims at implementing a self-monitoring system that collects, processes, and stores information of skin lesions through the automatic extraction of specific visual features. The selection of the features was based on the ABCD rule, which considers 4 visual criteria considered highly relevant for the detection of malignant melanoma. The algorithms used to extract these features are briefly described and the results achieved using images taken from the smartphone camera are discussed.

    The objective of this study was to be able to distinguish between healthy skin tissue and malignant ones, furthermore determining a unique pattern of roughness for each skin lesion by microtopographic analysis of the skin surface of Mexican patients during the period from April to October 2002. The standard technique used in this study for the diagnosis of skin cancer and the comparison of the results was the haematoxylin-eosin histopathological technique. Latex impressions were taken from skin lesions as well as from the healthy skin of each patient to serve as control samples. These impressions were analysed by the MICROTOP.03.MFC microtopographic system inspection. It was observed that when the tumour becomes rougher, more malign will be the lesion. On average, the melanoma present an increase of roughness of 67% compared to healthy skin, obtaining a roughness relation of 1:2.54. The percentage decreases to 49% (49%, 1:60) in the case of basal cell carcinoma and to 40% in pre-malignant lesions such as melanocytic nevus (40%, 1:150). In benign lesions such as the seborrhoea keratosis only a small increase in roughness was noted (4%, 1:0.72). Microtopographic inspection of the skin surface can be considered as a complementary diagnostic technique for skin cancer.

    Atypical vascular lesion of the skin is an uncommon usually benign condition, thus far reported almost exclusively from mammary skin after radiotherapy for carcinoma of the breast. Some clinical and histological overlap exists with early angiosarcoma, which can also occur on irradiated skin. The lesions are divided into vascular and lymphatic types, the first representing a higher risk for development of angiosarcoma and the latter being more common. This article reports a rare case of widespread, progressive, vascular-type atypical vascular lesion after repeated whole-body electron beam irradiation administered as treatment for mycosis fungoides.

    The complex inner layered structure of skin influences the photon diffusion inside the cutaneous tissues and determines the reflectance spectra formation. Phantoms are very useful tools to understand the biophysical meaning of parameters involved in light propagation through the skin. To simulate the skin reflectance spectrum, we realized a multilayered skin-like phantom and a multilayered skin phantom with a melanoma-like phantom embedded inside. Materials used were Al(2)O(3) particles, melanin of sepia officinalis and a calibrator for haematology systems dispersed in transparent silicon. Components were optically characterized with indirect techniques. Reflectance phantom spectra were compared with average values of in vivo spectra acquired on a sample of 573 voluntary subjects and 132 pigmented lesions. The phantoms' reflectance spectra agreed with those measured in vivo, mimicking the optical behaviour of the human skin. Further, the phantoms were optically stable and easily manageable, and represented a valid resource in spectra formation comprehension, in diagnostic laser applications and simulation model implementation, such as the Monte Carlo code for non-homogeneous media.

    2014-01-01

    Full Text Available Rhabdomyomatous mesenchymal hamartoma (RMH is a rare congenital lesion of the dermis and soft tissue, first described in 1986 as a striated muscle hamartoma. It has been reported under various names: striated muscle hamartoma, congenital midline hamartoma, hamartoma of cutaneous adnexa and mesenchyme. Etiology of this lesion is unknown; it has been hypothesized that be due to an abnormal migration of mesodermal stem cells during embryiogenesis or to right genetic defects. Patients with RMH occasionally have other congenital defects. RMH usually presents as a polypoid or papular cutaneous lesion that ranges in size from a few millimeters to 1-2 cm and occurs in areas where there is a superficial striated muscle, as the nose, chin, periorbital and anterior neck areas. Here we report a case of RMH in a 2-year-old child presenting with a congenital polypoid mass on the nasal skin.

    This study evaluated the influence of floor type on sow welfare in terms of lameness, claw lesions, and skin lesions. In a 2 × 3 factorial design, we have investigated the effect of rubber coverings on concrete floors and the effect of 3 levels of dietary zinc supplementation on locomotion and claw and skin lesions in group-housed sows. Six groups of 21 ± 4 hybrid sows were monitored during 3 successive reproductive cycles. The sows were group housed from d 28 after insemination (d 0) until 1 wk before expected farrowing date (d 108) in pens with either exposed concrete floors or concrete floors covered with rubber in part of the lying area and the fully slatted area. During each reproductive cycle, locomotion and skin lesions were assessed 4 times (d 28, 50, 108, and 140) and claw lesions were assessed twice (d 50 and 140). Results are given as least squares means ± SE. Locomotion and claw scores were given in millimeters, on analog scales of 150 and 160 mm, respectively. Here, we report on the effect of floor type, which did not interact with dietary zinc concentration ( > 0.10 for all variables). At move to group (d 28) and mid gestation (d 50), no differences between floor treatments were seen in locomotion ( > 0.10). At the end of gestation (d 108), sows housed on rubber flooring scored 9.9 ± 4.1 mm better on gait ( flooring at mid gestation (d 50). However, sows on rubber flooring scored worse for "vertical cracks in the wall horn" (difference of 3.4 ± 1.7 mm; = 0.04). At the end of lactation (d 140), both "white line" (difference of 2.9 ± 1 mm; = 0.02) and "claw length" (difference of 4.7 ± 1.4 mm; flooring. No differences for skin lesions were observed between floor treatments. The improved scores for gait toward the end of gestation and some types of claw disorders at mid gestation suggest that rubber flooring in group housing has a beneficial effect on the overall leg health of sows. The documented increase in vertical cracks in the wall horn at d

    In order to investigate the role of Th17 cytokines in the pathogenesis of psoriasis, reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of IL-17, IL-23 (p19/p40), and IL-6 in skin lesions and non-lesions of the patients with psoriasis and skin tissues of normal subjects. The results showed that the mRNA expression levels of IL-17, IL-23p19, IL-23p40 and IL-6 in psoriasis leision were significantly higher than those of non-leisions (1.231±0.843 vs 1.003±0.044, 1.166±0.142 vs 0.765±0.133, 1.125±0.104 vs 0.730±0.103, 1.186±0.222 vs 0.976±0.122, respectively, all P<0.05). Meanwhile, The expression levels of IL-17 mRNA,IL-23p19 mRNA, IL-23p40 mRNA and IL-6 mRNA were higher in non-leisions than those in normal skin tissues (1.003±0.044 vs 0.620±0.104, 0.765±0.133 vs 0.584±0.078, 0.730±0.103 vs 0.000±0.000, 0.976±0.122 vs 0.656±0.121, respectively, all P<0.05). The overexpression of Th17 cytokines in the skin lesions of patients with psoriasis may indicate that Th17 cytokines play a very important role in the immunopathogenesis of psoriasis.

    In vivo imaging of pigmented lesions in human skin was performed with a clinical multiphoton microscopy (MPM)-based tomograph (MPTflex, JenLab, Germany). Two-photon excited fluorescence was used for visualizing endogenous fluorophores such as NADH/FAD, keratin, melanin in the epidermal cells and elastin fibers in the dermis. Collagen fibers were imaged by second harmonic generation. Our study involved in vivo imaging of benign melanocytic nevi, atypical nevi and melanoma. The goal of this preliminary study was to identify in vivo the characteristic features and their frequency in pigmented lesions at different stages (benign, atypical and malignant) and to evaluate the ability of in vivo MPM to distinguish atypical nevi from melanoma. Comparison with histopathology was performed for the biopsied lesions. Benign melanocytic nevi were characterized by the presence of nevus cell nests at the epidermal-dermal junction. In atypical nevi, features such as lentiginous hyperplasia, acanthosis and architectural disorder were imaged. Cytological atypia was present in all the melanoma lesions imaged, showing the strongest correlation with malignancy. The MPM images demonstrated very good correlation with corresponding histological images, suggesting that MPM could be a promising tool for in vivo non-invasive pigmented lesion diagnosis, particularly distinguishing atypical nevi from melanoma.

    Full Text Available Envenomations caused by Loxosceles (brown spider have been reported throughout the world. Clinical signs associated to bites of these spiders involve dermonecrotic lesions and intense local inflammatory response, besides systemic manifestations such as intravascular hemolysis, thrombocytopenia, disseminated intravascular coagulation and acute renal failure. The present study aimed to report and to describe dermonecrotic lesions probably caused by a Loxosceles envenomation in a four year-old poodle female dog, treated at the Dermatology Service of the Veterinary Hospital of the Veterinary Medicine and Animal Husbandry School, São Paulo State University, Botucatu, Brazil. Initially, the animal presented two skin lesions with blackish aspect that evolved into ulcerative crusts. The owner reported the presence of a brown spider near the place where the animal spent most of the time. Histological examination of lesions revealed necrosis of the epidermis extending to adnexa and panniculi, which is compatible with Loxosceles bite reaction. The animal was treated with systemic antibiotic and local curatives. Lesions healed by second intention in two months.

    A significant proportion of groundwater in south Asia is contaminated with arsenic. Pakistan has low levels of arsenic in groundwater compared with China, Bangladesh and India. A representative multi-stage cluster survey conducted among 3874 persons > or = 15 years of age to determine the prevalence of arsenic skin lesions, its relation with arsenic levels and cumulative arsenic dose in drinking water in a rural district (population: 1.82 million) in Pakistan. Spot-urine arsenic levels were compared among individuals with and without arsenic skin lesions. In addition, the relation of age, body mass index, smoking status with arsenic skin lesions was determined. The geographical distribution of the skin lesions and arsenic-contaminated wells in the district were ascertained using global positioning system. The total arsenic, inorganic and organic forms, in water and spot-urine samples were determined by atomic absorption spectrophotometry. The prevalence of skin lesions of arsenic was estimated for complex survey design, using surveyfreq and surveylogistic options of SAS 9.1 software.The prevalence of definitive cases i.e. hyperkeratosis of both palms and soles, was 3.4 per 1000 and suspected cases i.e. any sign of arsenic skin lesions (melanosis and/or keratosis), were 13.0 per 1000 among > or = 15-year-old persons in the district. Cumulative arsenic exposure (dose) was calculated from levels of arsenic in water and duration of use of current drinking water source. Prevalence of skin lesions increases with cumulative arsenic exposure (dose) in drinking water and arsenic levels in urine. Skin lesions were 2.5-fold among individuals with BMI Pakistan. Further investigations and focal mitigation measures for arsenic may be carried out alongside Indus River.

    Anti-annexin1 antibodies are associated with the subtypes of cutaneous lupus and are elevated in systemic lupus erythematosus (SLE) patients. In this study, we investigated the correlation of this antibody with the incidence of SLE skin lesions. The presence of anti-annexin1-IgG and-IgM determined by Western blot was no different among healthy controls and SLE patients with and without skin lesions. Serum levels of anti-annexin1-IgG and -IgM measured by enzyme-linked immunosorbent assay were comparable between patients with and without skin lesions, whereas anti-annexin1-IgM was lower in SLE patients than in healthy controls. Annexin1 was abundantly detected in each epidermal layer in lupus lesional skin. Additionally, anti-annexin1-IgG was higher in SLE patients with arthritis and negatively correlated with white blood cells (WBC). Anti-annexin1-IgM was higher in patients with antinuclear antibody (ANA)-positive sera, and was positively related to hemoglobin and total serum IgM. Collectively, anti-annexin1 antibodies are not related to the incidence of skin lesions in SLE, and annexin1 abundantly distributes in epidermis in lesional skin.

    Video sensors and agricultural IoT ( internet of things) have been widely used in the informa-tionalized orchards.In order to realize intelligent-unattended early warning for disease-pest, this pa-per presents convolutional neural network ( CNN) early warning for apple skin lesion image, which is real-time acquired by infrared video sensor.More specifically, as to skin lesion image, a suite of processing methods is devised to simulate the disturbance of variable orientation and light condition which occurs in orchards.It designs a method to recognize apple pathologic images based on CNN, and formulates a self-adaptive momentum rule to update CNN parameters.For example, a series of experiments are carried out on the recognition of fruit lesion image of apple trees for early warning. The results demonstrate that compared with the shallow learning algorithms and other involved, well-known deep learning methods, the recognition accuracy of the proposal is up to 96.08%, with a fairly quick convergence, and it also presents satisfying smoothness and stableness after conver-gence.In addition, statistics on different benchmark datasets prove that it is fairly effective to other image patterns concerned.

    Introduction Attempts to determine the quality of life are advisable in patients with ulcers as the group affected with this problem is relatively large. According to one Polish randomized trial, approximately 0.3–2% of the adult population suffers from active or healed venous ulcers. Aim To compare the quality of life of patients with leg ulcers of venous and arterial etiology and those with lower limb skin lesions due to chronic venous insufficiency. Material and methods This study included 90 consecutive patients with ulcers of venous (n = 30) or arterial etiology (n = 30), or patients with trophic disorders of the skin associated with chronic venous insufficiency (n = 30) treated at the Venous Ulceration Outpatient Clinic and at the Department and Clinic of General Surgery, Dr. J. Biziel Memorial University Hospital No. 2, in Bydgoszcz. This study was designed as a questionnaire survey and included the Skindex-29 instrument for the assessment of quality of life in patients with dermatological conditions. Results Overall, the global Skinndex-29 scores of all studied participants ranged between 37 and 136 points, 23.93 points on average. The analyzed groups of patients differed significantly with respect to the average level of the global quality of life determined using the Skindex-29 questionnaire. Conclusions Significant differences were observed in the global quality of life of patients who suffered from venous or arterial leg ulcers or skin lesions resulting from chronic venous insufficiency.

    Full Text Available Of 14 cases who underwent this operation only in one of them because of infection in operation site, we had to extract the expander. Also, in the first day of the operation that we injected serum inside the expander of two other patients, the wound opened up and the expander appeared and came out automatically. The remaining ten patients have tolerated the operation after treatment period without any complications and good result was achieved. This method in covering up skin lesions and in eliminating burn as well as old wound scars was very effective and the patient become satisfied because there was no need to remove skin from other parts of the body and thus no new scars would have been created. The only problems in this method of treatment were its duration which is needed for injection inside the expander as well as bad appearance in operation region and these problems cause the patients to become depressed and to become isolated from the public for a long period. For the past three years that we used this method for covering skin lesions in different parts of the body and even in treating extensive spots and the hemantrium we achieved excellent results and the report will subsequently be submitted.

    We investigated the aberrant promoter methylation status of 12 genes in skin lesions, both malignant (basal cell carcinomas (BCCs), n=68 and squamous cell carcinomas (SCCs), n=35) and non-malignant (tags, n=58) skin lesions and compared the results of lesions from sun exposed (SE) and sun protected (SP) regions. Methylation was studied using a methylation specific PCR (MSP) and methylation of CDH1 was also measured using a semi-quantitative fluorescence based real-time MSP method. The methylation index (MI) was calculated as the methylated fraction of the genes examined. In this report, we found high frequencies of methylation of several known or suspected tumor suppressor genes in tags and skin cancers. Among the 12 genes, for the cadherin genes CDH1 and CDH3 and for two of the laminin 5 encoding genes LAMA3 and LAMC2 methylation frequencies greater than 30% were noted in one or more specimen types. We investigated whether methylation was tumor related. Surprisingly, the differences in the methylation profile of genes among the three specimen types were modest, and the MI, indicators of overall methylation frequencies, was nearly identical. However, significant differences were noted in the frequencies of methylation among the three specimen types for the genes RASSF1A (P=0.002), CDH1 (P=0.007) and one or more of three CAD genes (P=0.02). Methylation was highly significantly related to sun exposure, and sun protected specimens had little or no methylation. As methylation of CDH1 was completely SE specific we analyzed all the skin samples using a semi-quantitative real-time PCR assay for the CDH1 gene. The concordance between standard MSP and real-time MSP for all the samples (n=161) was 75% (P<0.0001). While weak signals were detected in the SP samples by real time PCR, the differences between SE and SP specimens were 148 fold for tags and 390 fold for BCCs. These differences were highly significant (P<0.0001). These findings suggest that methylation commences in

  20. Experimental investigation of monochromic optic radiation effect on development of local radiation lesions of the skin. Communication 1. The course of local radiation lesions of the skin in rats

    International Nuclear Information System (INIS)

    The influence of different ranges of monochromic optic radiation on the skin of white rats after local x-ray exposure are studied. Photomodulation with light diodes of red, green and blue light positively influenced development of local radiation lesions of skin of white rats, reduced their frequency, severity and accelerated heating. All used types of visual light produced positively influenced the development of local radiation lesions but the effect of each range had the peculiarities. Comparative analysis of preventive efficacy of the three types of optic radiation allow to make a preliminary conclusion that blue light can be the most effective in prevention of local radiation lesions

  1. Tc99m - Dextran Sentinel Node detection: Improvement of clinical decision making in malignant skin lesions

    International Nuclear Information System (INIS)

    Introduction: Preoperative lymphoscintigraphy and sentinel node detection are necessary to perform selective lymphadenectomies for staging purposes in malignant skin lesions. Aim: Our goal was to assess the usefulness of Tc99m-Dextran lymphoscintigraphy and sentinel node detection in the nodal staging of malignant skin lesions. Materials and Methods: Retrospectively an experienced oncologic surgeon defined the nodal staging approach he would have had based on the clinical information excluding only the scintigraphic sentinel node detection result in 44 consecutive patients, 21 men, ages 5 - 79, with melanoma (41), Merkel cell tumor (2) and squamous cell tumor (1). We analyze the changes introduced by the use of sentinel node detection in view of anatomopathological findings and clinical outcome. Results: In 35/44 patients no adenectomy would have been performed. Thus, leaving 3 (+) sentinel nodes and 32 (-) sentinel nodes undetected. One of this 32 patients would have had unnecessary radiotherapy because of unknown nodal status. Two of these 32 patients, with malignant melanoma, had metastasis after 15 and 22 month to 1/16 regional lymph nodes and to the skin close to the original lesion respectively. In two other patients the sentinel node could not be identified by scintigraphy : one had negative pathology of regional lymphadenectomy and the other is healthy 20 month after surgery. In 9/44 patients regional adenectomy would have excised 4 (+) sentinel nodes, 4 (-) sentinel nodes and left 1 (+) sentinel node located in an unexpected lymphatic bed. Conclusion: Preoperative sentinel node location guides the surgeon to a rational, limited lymph node excision avoiding staging errors. Selective adenectomy has less complications thus permitting anatomopathological evaluation even for lower risk patients

    Leprosy (or Hansen's disease) is a curable chronic infectious disease caused by the acid-fast bacillus Mycobacterium leprae. While leprosy remains one of the most common causes of neuropathy worldwide, its rarity in the UK means that many doctors are unfamiliar with the typical clinical features. This is problematic because early recognition and treatment is vital in order to minimise disease-related complications such as nerve injury. We describe a 75-year-old man who presented with multiple mononeuropathy (mononeuritis multiplex, particularly affecting the ulnar nerves) and typical granulomatous skin lesions, in whom the diagnosis was made on the basis of skin biopsy. We highlight the clinical features, investigations and treatment of the patient, and provide information about the epidemiology and pathogenesis of leprosy. PMID:25874829

    A significant proportion of groundwater in south Asia is contaminated with arsenic. Pakistan has low levels of arsenic in groundwater compared with China, Bangladesh and India. A representative multi-stage cluster survey conducted among 3874 persons {>=}15 years of age to determine the prevalence of arsenic skin lesions, its relation with arsenic levels and cumulative arsenic dose in drinking water in a rural district (population: 1.82 million) in Pakistan. Spot-urine arsenic levels were compared among individuals with and without arsenic skin lesions. In addition, the relation of age, body mass index, smoking status with arsenic skin lesions was determined. The geographical distribution of the skin lesions and arsenic-contaminated wells in the district were ascertained using global positioning system. The total arsenic, inorganic and organic forms, in water and spot-urine samples were determined by atomic absorption spectrophotometry. The prevalence of skin lesions of arsenic was estimated for complex survey design, using surveyfreq and surveylogistic options of SAS 9.1 software.The prevalence of definitive cases i.e. hyperkeratosis of both palms and soles, was 3.4 per 1000 and suspected cases i.e. any sign of arsenic skin lesions (melanosis and/or keratosis), were 13.0 per 1000 among {>=}15-year-old persons in the district. Cumulative arsenic exposure (dose) was calculated from levels of arsenic in water and duration of use of current drinking water source. Prevalence of skin lesions increases with cumulative arsenic exposure (dose) in drinking water and arsenic levels in urine. Skin lesions were 2.5-fold among individuals with BMI <18.5 kg/m{sup 2}. Geographically, more arsenic-contaminated wells and skin lesions were alongside Indus River, suggests a strong link between arsenic contamination of groundwater with proximity to river.This is the first reported epidemiological and clinical evidence of arsenic skin lesions due to groundwater in Pakistan.

    When sarcoidosis is suspected, a patient should be meticulously examined for dermal changes, the favorite sites of which are the skin of the face, ears, upper and lower extremities, and trunk. Elements may vary in number from solitary to multiple. When dermal changes are suspected of sarcoidosis, a dermatologist should examine the patient and, if there are some doubts about the nature of dermal elements, biopsy and histological study should be made since the morphological verification of the diagnosis primarily requires the use of extrapulmonary sites of the process, namely superficial peripheral lymph nodes, as well as the skin. The findings suggest that skin sarcoidosis characterized by the long-term chronic or progressive course is encountered at different (X-ray) stages of sarcoidosis of respiratory organs and is of poor prognostic value. The severity of dermal manifestations is no less and, in individual cases, more significant than pulmonary symptoms. Great or ugly skin lesions require prednisolone treatment. In some cases, long-term therapy cannot yield a result. Delagil treatment of dermal manifestations remains to be effective.

    Objective: To observe the expression of CDI3/APN in peripheral blood lymphocytes and skin lesions of patients with advanced psoriasis vulgaris, and discuss its effect on the pathogenesis of psoriasis. Methods: CDI 3 expression in peripheral blood lymphocytes and skin lesions was detected by flow cytometry and immunohistochemical technique, respectively. Results were compared with those of healthy controls. Results: CD13 expression was significantly higher in peripheral blood lymphocytes of patients with advanced psoriasis vulgaris than in that of healthy controls, and in skin lesions than in healthy skin tissues. The expression was mainly in the suprabasal layers of skin lesions, andpositively correlated to PASI (R=0.78029). Conclusion: The significantly higher expression of CDI3 in peripheralblood lymphocytes and skin lesions of the patients with advanced psoriasis vulgaris probably is related to immunological abnormality, blood vessel abnormality and proliferation of keratinocyte in the pathogenic course of psoriasis. It may be a novel and effective way to treat psoriasis with specific CD13 inhibitors.

    Full Text Available OBJETIVO: Ainda é desconhecida a relação do diabetes com fatores determinantes ou precipitantes de lesões dermatológicas em pacientes diabéticos. Assim, o objetivo do estudo foi investigar a presença de lesões cutâneas, não referidas pelo paciente diabético e sua relação com o controle metabólico da doença. MÉTODOS: Foram examinados 403 pacientes, dos quais 31% eram diabéticos do tipo 1 e 69% do tipo 2. Em ambulatório de um hospital universitário, os pacientes foram atendidos por endocrinologista para a avaliação endócrino-metabólica e por dermatologista para a avaliação dermatológica. O grau de controle metabólico foi documentado em 136 pacientes por meio da dosagem de hemoglobina glicada. RESULTADOS: Houve predomínio de dermatofitoses (82,6%, seguido de grupo de dermatoses como acne e degeneração actínica (66,7%, piodermites (5%, tumores cutâneos (3% e necrobiose lipoídica (1%. Entre as dermatoses mais comuns em diabéticos, foram confirmados com exame histológico: dois diagnósticos de necrobiose (0,4%, cinco de dermopatia diabética (1,2% e três casos de mal perfurante plantar (0,7%. Os valores da hemoglobina glicada foram: 7,2% em pacientes com controle metabólico adequado nos dois tipos de diabetes e de 11,9% e 12,7% nos tipos 1 e 2, respectivamente, com controle inadequado. Nos pacientes com controle metabólico inadequado foi observada freqüência maior de dermatofitoses, em ambos os tipos de diabetes. CONCLUSÕES: Os dados revelaram freqüência elevada de lesão dermatológica nos pacientes diabéticos, especialmente dermatofitoses. Dessa forma, o descontrole metabólico do diabético propicia maior suscetibilidade a infecções cutâneas.OBJECTIVE: It is yet unknown the relationship between diabetes and determinants or triggering factors of skin lesions in diabetic patients.

    Full Text Available Temporal artery calciphylaxis has rarely been described in chronic kidney disease patients on dialysis. We report a case of 72-year-old Caucasian man with multiple comorbidities and end-stage renal disease on dialysis who presented with temporal artery calcification leading to bilateral loss of vision followed by extensive skin lesions including one on glans penis. While on peritoneal dialysis, he developed anterior ischemic optic neuropathy, had no improvement on high dose steroids, and temporal artery biopsy showed marked calcification without any evidence of vasculitis. Few weeks later on hemodialysis, he developed widespread cutaneous lesions on extremities and penile necrosis with skin biopsy revealing calciphylaxis. On literature review of calciphylaxis in chronic kidney disease, we found only four cases of temporal artery calciphylaxis leading to anterior ischemic optic neuropathy and blindness. We believe this is the first case in which the rare temporal artery calciphylaxis and the uncommon penile necrosis are being described together. The objective is to emphasize the need to recognize this condition early in the CKD patients on dialysis presenting with visual symptoms as the different treatment strategies may help prevent complete loss of vision and also modify or prevent a full blown calciphylaxis.

    Full Text Available Immunosuppressive drugs are commonly used for the treatment of inflammatory bowel disease. Patients receiving immunosuppressants are susceptible to a variety of infections with opportunistic pathogens. We present a case of skin infection with Mycobacterium chelonae in a 60-year-old Caucasian woman with ulcerative colitis who had been treated with corticosteroids and azathioprine. The disease manifested with fever and rash involving the right leg. Infliximab was administered due to a presumptive diagnosis of pyoderma gangrenosum, leading to worsening of the clinical syndrome and admission to our hospital. Routine cultures from various sites were all negative. However, Ziehl-Neelsen staining of pus from the lesions revealed acid-fast bacilli, and culture yielded a rapidly growing mycobacterium further identified as M. chelonae. The patient responded to a clarithromycin-based regimen. Clinicians should be aware of skin lesions caused by atypical mycobacteria in immunocompromised patients with inflammatory bowel disease. Furthermore, they should be able to thoroughly investigate and promptly treat these conditions.

    Full Text Available Background:The etiology of skin tags (STs is not fully understood. A relation to diabetes mellitus and obesity was suggested. Few studies of possible mast cells (MCs involvement were reported. Tyrptase is a mast cell mediator and a potent fibroblast growth factor. It may provide a molecular link between mast cell activation and fibrosis. Aims: The aim was to assess clinical and laboratory findings in patients with STs, and the possible link between obesity, dyslipidemia, and lesional MC count/tryptase expression. Materials and Methods: A total of 20 patients with STs were subjected to clinical examination, estimation of body mass index (BMI, fasting blood glucose (FBG, postprandial blood glucose (PPBG, serum cholesterol and triglycerides, abdominal ultrasound for fatty liver assessment, in addition to study of MCs through staining for MC tryptase in two skin biopsies; lesional and nonlesional (control. Results:All patients showed abnormally high BMI and hypertriglyceridemia, with abnormal sonographic pattern in 15 patients (75%. STs number positively correlated with the age of patients. STs showed significantly higher MC counts and tryptase expression, compared with control skin ( P < 0.001, with no correlation of the STs number or MC count with BMI, FBG, PPBG or serum cholesterol. Obese patients showed a significantly higher MC count than overweight and there was a positive correlation between MC count and serum triglycerides. Axilla and under breast STs showed a higher MC count compared with other sites. Conclusions:STs seem to be related to obesity and hypertriglyceridemia. MCs with their tryptase are possibly involved in pathogenesis of STs. MC count is related to the associated factors; obesity and serum triglycerides. MC tryptase expression is a reliable method for accurate tissue MC counting.

    Incomplete arsenic (As) methylation has been considered a risk factor of As-related diseases. This study aimed to examine the difference of urinary As metabolites and the methylation capacity between subjects with and without skin lesions. Urinary inorganic arsenic (iAs), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA) were analyzed. The percentage of each As species (iAs%, MMA%, and DMA%), the primary methylation index (PMI) and secondary methylation index (SMI) were calculated. The results showed that subjects with skin lesions have higher levels of urinary iAs (99.08 vs. 70.63 μg/g Cr, p = 0.006) and MMA (69.34 vs. 42.85 μg/g Cr, p = 0.016) than subjects without skin lesions after adjustment for several confounders. Significant differences of urianry MMA% (15.49 vs. 12.11, p = 0.036) and SMI (0.74 vs. 0.81, p = 0.025) were found between the two groups. The findings of the present study suggest that subjects with skin lesions may have a lower As methylation capacity than subjects without skin lesions.

    Over the centuries, traditional Chinese medicine (TCM) and Western medicine have traveled along parallel lines with no opportunity for collaboration. In recent decades, while an interest in TCM has been growing among Western clinicians, progress has been made in the comprehension of pathogenic mechanisms of skin disorders, and the communication between Western and Eastern medicines has become more and more intensive. In this paper, the authors discuss TCM remedies used in the treatment of autoimmune bullous disorders (pemphigus and bullous pemphigoid) and lichen planus. Future studies on the active components of the TCM will certainly shed new light on the still obscure aspects of some dermatologic diseases. PMID:26380506

    The common octopus Octopus vulgaris Cuvier, 1798 is extremely important in fisheries and is a useful protein source in most Mediterranean countries. Here we investigated pathogens associated with skin lesions in 9 naturally deceased specimens that included both cultured and wild common octopus. Within 30 min after death, each octopus was stored at 4°C and microbiologically examined within 24 h. Bacterial colonies, cultured from swabs taken from the lesions, were examined using taxonomical and biochemical analyses. Vibrio alginolyticus and V. parahaemolyticus were only isolated from cultured animals. A conventional PCR targeting the 16S ribosomal RNA (rRNA) gene and sequencing were performed on 2 bacterial isolates that remained unidentified after taxonomical and biochemical analysis. The sequence results indicated that the bacteria had a 99% identity with Lactococcus garvieae and Photobacterium swingsii. L. garvieae was confirmed using a specific PCR based on the 16S-23S rRNA internal transcribed spacer region, while P. swingsii was confirmed by phylogenetic analyses. Although all animals examined were found to be infected by the protozoan species Aggregata octopiana localised in the intestines, it was also present in skin lesions of 2 of the animals. Betanodavirus was detected in both cultured and wild individuals by cell culture, PCR and electron microscopy. These findings are the first report of L. garvieae and betanodavirus from skin lesions of common octopus and the first identification of P. swingsii both in octopus skin lesions and in marine invertebrates in Italy.

    Full Text Available In this study, the effects of the origin of xanthan used, in combination with chitosan, to prepare films for the treatment of skin lesions were evaluated. The characteristics of the films obtained with xanthan commercially available for the food industry sector and xanthan originated from a fermentation process conducted in a pilot plant were compared. Results showed that the source did not strongly interfere in many of the properties of the films, such as the mechanical properties, cytotoxicity to L929 cells, absorption of simulated body fluid and culture medium, stability in water and saline solution. Hence, even though the properties of biopolymers of different sources might vary, the films prepared with two distinct types of xanthan gum could be considered as potentially safe and similar in terms of relevant characteristics considering the aimed application.

    Reported in this paper is an attack of two adolescents on a man who was killed in the fight, with several kitchen knives being used, including two with grooved and wave-grooved blades. One of the offenders held the victim tight from behind and was injured by his attacking accomplice++. A grid mark on the left side of the victim's face and the left forearm of the second offender in the back supported the assumption of a knife with simple wave profile. Skin lesions of finer structure below the left ear and on the left forearm of the victim suggested involvement of a smaller kitchen knife with groove-milled wave profile. Offender-victim position and course of offence were verified and confirmed by evaluation of these specific findings.

    Lewisite is a potent chemical warfare arsenical vesicant that can cause severe skin lesions. Today, lewisite exposure remains possible during demilitarization of old ammunitions and as a result of deliberate use. Although its cutaneous toxicity is not fully elucidated, a specific antidote exists, the British anti-lewisite (BAL, dimercaprol) but it is not without untoward effects. Analogs of BAL, less toxic, have been developed such as meso-2,3-dimercaptosuccinic acid (DMSA) and have been employed for the treatment of heavy metal poisoning. However, efficacy of DMSA against lewisite-induced skin lesions remains to be determined in comparison with BAL. We have thus evaluated in this study the therapeutic efficacy of BAL and DMSA in two administration modes against skin lesions induced by lewisite vapor on SKH-1 hairless mice. Our data demonstrate a strong protective efficacy of topical application of dimercapto-chelating agents in contrast to a subcutaneous administration 1 h after lewisite exposure, with attenuation of wound size, necrosis and impairment of skin barrier function. The histological evaluation also confirms the efficacy of topical application by showing that treatments were effective in reversing lewisite-induced neutrophil infiltration. This protective effect was associated with an epidermal hyperplasia. However, for all the parameters studied, BAL was more effective than DMSA in reducing lewisite-induced skin injury. Together, these findings support the use of a topical form of dimercaprol-chelating agent against lewisite-induced skin lesion within the first hour after exposure to increase the therapeutic management and that BAL, despite its side-effects, should not be abandoned. - Highlights: • Topically applied dimercapto-chelating agents reduce lewisite-induced skin damage. • One topical application of BAL or DMSA is sufficient to reverse lewisite effects. • Topical BAL is more effective than DMSA to counteract lewisite-induced skin damage.

    Lewisite is a potent chemical warfare arsenical vesicant that can cause severe skin lesions. Today, lewisite exposure remains possible during demilitarization of old ammunitions and as a result of deliberate use. Although its cutaneous toxicity is not fully elucidated, a specific antidote exists, the British anti-lewisite (BAL, dimercaprol) but it is not without untoward effects. Analogs of BAL, less toxic, have been developed such as meso-2,3-dimercaptosuccinic acid (DMSA) and have been employed for the treatment of heavy metal poisoning. However, efficacy of DMSA against lewisite-induced skin lesions remains to be determined in comparison with BAL. We have thus evaluated in this study the therapeutic efficacy of BAL and DMSA in two administration modes against skin lesions induced by lewisite vapor on SKH-1 hairless mice. Our data demonstrate a strong protective efficacy of topical application of dimercapto-chelating agents in contrast to a subcutaneous administration 1 h after lewisite exposure, with attenuation of wound size, necrosis and impairment of skin barrier function. The histological evaluation also confirms the efficacy of topical application by showing that treatments were effective in reversing lewisite-induced neutrophil infiltration. This protective effect was associated with an epidermal hyperplasia. However, for all the parameters studied, BAL was more effective than DMSA in reducing lewisite-induced skin injury. Together, these findings support the use of a topical form of dimercaprol-chelating agent against lewisite-induced skin lesion within the first hour after exposure to increase the therapeutic management and that BAL, despite its side-effects, should not be abandoned. - Highlights: • Topically applied dimercapto-chelating agents reduce lewisite-induced skin damage. • One topical application of BAL or DMSA is sufficient to reverse lewisite effects. • Topical BAL is more effective than DMSA to counteract lewisite-induced skin damage

    Full Text Available Background and Design: Bullous pemphigoid (BP is a chronic, autoimmune, subepidermal blistering disease. The aim of this study was to determine the clinico-epidemiologic data’s of patients diagnosed as BP in our clinic and compare these data with other studies in our country and in the world. Material and Method: We researched the documents of BP cases diagnosed by clinical and histopathological examinations from January 2009 to January 2013, retrospectively. We evaluated clinical and dermographical characteristics of all patients such as age, sex, existence of oral mucosal lesions, association of pruritus, duration of disease, presence of triggering factors, features of skin lesions, results of direct immunofluorescence (DIF investigation, drug intake, recurrence and mortality rates and causes of detected mortality. Results: Of the 29 patients included in the study %48,3 were female, %51,7 were male. The average age was 70,17 and the mean duration of disease was 15.41 months. In five cases oral mucosal involvement and in 24 cases pruritus was detected. Drugs in three cases and malignity in one case were assessed as triggering factors. The results of DIF investigation revealed the linear IgG and C3 deposition at the dermoepidermal junction in 12 cases, C3 deposition in 10 cases. The initial treatment was topical corticosteroid in 11, tetracycline and nicotinamide combination in six, systemic corticosteroid in 10 individuals. After initial therapy recurrence appeared in 7 patients in one year. Mortality during hospitalization was observed in 2 cases. Conclusions: We presented the clinical and epidemiological features of patients diagnosed as BP in our clinics in the last three years. Because of having different ethnical originated, heterogeneous population of our city, we believe that our investigation will contribute to having opinion about epidemiology of BP in our country. Nevertheless, prospective, long term and multicentre studies based on

    We previously reported clinical performance of a novel noninvasive and quantitative PCR (qPCR)-based molecular diagnostic assay (the pigmented lesion assay; PLA) that differentiates primary cutaneous melanoma from benign pigmented skin lesions through two target gene signatures, LINC00518 (LINC) and preferentially expressed antigen in melanoma (PRAME). This study focuses on analytical characterization of this PLA, including qPCR specificity and sensitivity, optimization of RNA input in qPCR to achieve a desired diagnostic sensitivity and specificity, and analytical performance (repeatability and reproducibility) of this two-gene PLA. All target qPCRs demonstrated a good specificity (100%) and sensitivity (with a limit of detection of 1-2 copies), which allows reliable detection of gene expression changes of LINC and PRAME between melanomas and nonmelanomas. Through normalizing RNA input in qPCR, we converted the traditional gene expression analyses to a binomial detection of gene transcripts (i.e., detected or not detected). By combining the binomial qPCR results of the two genes, an improved diagnostic sensitivity (raised from 52%- 65% to 71% at 1 pg of total RNA input, and to 91% at 3 pg of total RNA input) was achieved. This two-gene PLA demonstrates a high repeatability and reproducibility (coefficient of variation commercial processing of clinical samples. PMID:27505074

    Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) syndrome is a newly characterized autoinflammatory disorder, caused by mutations in PSMB8. It is characterized by early-onset fevers, accompanied by a widespread, violaceous, and often annular cutaneous eruption. Although the exact pathogenesis of this syndrome is still obscure, it is postulated that the inflammatory disease manifestations stem from excess secretion of interferons. Based on preliminary blood cytokine and gene expression studies, the signature seems to come mostly from type I interferons, which are proposed to lead to the recruitment of immature myeloid cells into the dermis and subcutis. In this study, we systematically analyzed skin biopsies from 6 patients with CANDLE syndrome by routine histopathology and immunohistochemistry methods. Skin lesions showed the presence of extensive mixed dermal and subcutaneous inflammatory infiltrate, composed of mononuclear cells, atypical myeloid cells, neutrophils, eosinophils, and some mature lymphocytes. Positive LEDER and myeloperoxidase staining supported the presence of myeloid cells. Positive CD68/PMG1 and CD163 staining confirmed the existence of histiocytes and monocytic macrophages in the inflammatory infiltrate. CD123 staining was positive, demonstrating the presence of plasmacytoid dendritic cells. Uncovering the unique histopathological and immunohistochemical features of CANDLE syndrome provides tools for rapid and specific diagnosis of this disorder and further insight into the pathogenesis of this severe life-threatening condition.

    We have shown previously that in addition to IL-4, IL-5 and IL-10, antigen-specific interferon-gamma (IFN-gamma) production by spleen cells from ovalbumin (OVA)/Alum-immunized mice is inhibited by the administration of royal jelly (RJ). Since it has been shown that both Th1 and Th2 cytokines play pathogenic roles in the generation of atopic dermatitis (AD), we have examined whether RJ suppresses the development of AD-like skin lesions in NC/Nga mice induced by repeated application of picryl chloride (PiCl) under specific pathogen-free (SPF) conditions. Oral administration of RJ to the PiCl-treated NC/Nga mice inhibited the development of AD-like skin lesions in these mice as exemplified by the significant decrease in the total skin severity scores and the decrease in hypertrophy, hyperkeratosis, and infiltration of the epidermis and corium by inflammatory cells. IFN-gamma production by spleen cells from PiCl-treated NC/Nga mice in response to TNP-KLH was partially but significantly inhibited by the oral administration of RJ, while IFN-gamma production by Con A-stimulated spleen cells was not affected. Since inducible nitric oxide (NO) synthase (iNOS)-derived NO has been suggested as an important immunoregulatory mediator in inflammatory autoimmune diseases, we have also examined the expression of iNOS in the dorsal skin lesions of PiCl-treated NC/Nga mice. Interestingly, the expression of iNOS was significantly increased in the skin lesions of RJ-administered mice compared with those of control PBS-administered mice. Thus, our results suggest that RJ suppresses the development of AD-like skin lesions in PiCl-treated NC/Nga mice, possibly by a combination of down-regulating TNP-specific IFN-gamma production and up-regulating iNOS expression.

    Full Text Available Resurfacing is a treatment to remove acne and chicken pox scars, and changes in the skin due to ageing. Machines : Both ablative and nonablative lasers are available for use. CO 2 laser is the gold standard in ablative lasers. Detailed knowledge of the machines is essential. Indications for CO 2 laser: Therapeutic indications: Actinic and seborrheic keratosis, warts, moles, skin tags, epidermal and dermal nevi, vitiligo blister and punch grafting, rhinophyma, sebaceous hyperplasia, xanthelasma, syringomas, actinic cheilitis angiofibroma, scar treatment, keloid, skin cancer, neurofibroma and diffuse actinic keratoses. CO 2 laser is not recommended for the removal of tattoos. Aesthetic indications: Resurfacing for acne, chicken pox and surgical scars, periorbital and perioral wrinkles, photo ageing changes, facial resurfacing. Physicians′ qualifications: Any qualified dermatologist (DVD or MD may practice CO 2 laser. The dermatologist should possess postgraduate qualification in dermatology and should have had specific hands-on training in lasers either during postgraduation or later at a facility which routinely performs laser procedures under a competent dermatologist/plastic surgeon, who has experience and training in using lasers. For the use of CO 2 lasers for benign growths, a full day workshop is adequate. As parameters may vary in different machines, specific training with the available machine at either the manufacturer′s facility or at another centre using the machine is recommended. Facility: CO 2 lasers can be used in the dermatologist′s minor procedure room for the above indications. However, when used for full-face resurfacing, the hospital operation theatre or day care facility with immediate access to emergency medical care is essential. Smoke evacuator is mandatory. Preoperative counseling and Informed consent Detailed counseling with respect to the treatment, desired effects, possible postoperative complications, should be

  8. Multispectral imaging and artificial neural network: mimicking the management decision of the clinician facing pigmented skin lesions

    International Nuclear Information System (INIS)

    Various instruments based on acquisition and elaboration of images of pigmented skin lesions have been developed in an attempt to in vivo establish whether a lesion is a melanoma or not. Although encouraging, the response of these instruments, e.g. epiluminescence microscopy, reflectance spectrophotometry and fluorescence imaging, cannot currently replace the well-established diagnostic procedures. However, in place of the approach to instrumentally assess the diagnosis of the lesion, recent studies suggest that instruments should rather reproduce the assessment by an expert clinician of whether a lesion has to be excised or not. The aim of this study was to evaluate the performance of a spectrophotometric system to mimic such a decision. The study involved 1794 consecutively recruited patients with 1966 doubtful cutaneous pigmented lesions excised for histopathological diagnosis and 348 patients with 1940 non-excised lesions because clinically reassuring. Images of all these lesions were acquired in vivo with a multispectral imaging system. The data set was randomly divided into a train (802 reassuring and 1003 excision-needing lesions, including 139 melanomas), a verify (464 reassuring and 439 excision-needing lesions, including 72 melanomas) and a test set (674 reassuring and 524 excision-needing lesions, including 76 melanomas). An artificial neural network (ANN1) was set up to perform the classification of the lesions as excision-needing or reassuring, according to the expert clinicians' decision on how to manage each examined lesion. In the independent test set, the system was able to emulate the clinicians with a sensitivity of 88% and a specificity of 80%. Of the 462 correctly classified as excision-needing lesions, 72 (95%) were melanomas. No major variations in receiver operating characteristic curves were found between the test and the train/verify sets. On the same data set, a further artificial neural network (ANN2) was then architected to perform

    Vascular skin lesions comprise a wide and heterogeneous group of malformations and tumors that can be correctly diagnosed based on natural history and physical examination. However, considering the high incidence of such lesions, a great number of them can be misdiagnosed. In addition, it is not so rare that an aggressive amelanotic melanoma can be misdiagnosed as a vascular lesion. In this regard, dermoscopy and confocal laser microscopy examination can play a central role in increasing the specificity of the diagnosis of such lesions. In fact, the superiority of these tools over clinical examination has encouraged dermatologists to adopt these devices for routine clinical practice, with a progressive spread of their use. In this review, we will go through the dermoscopic and the confocal laser microscopy of diagnosis of most frequent vascular lesions (i.e., hemangiomas angiokeratoma, pyogenic granuloma, angiosarcoma) taking into particular consideration the differential diagnosis with amelanotic melanoma.

    Circulating and bound IgA antibodies can be found in the autoimmune blistering diseases, but their prevalence, clinical relevance and target antigens remain unknown. Thirty-two patients with pemphigus, 73 with bullous pemphigoid and 28 with mucous membrane pemphigoid were studied retrospectively. Direct immunofluorescence (DIF) analysis of IgG, IgA, IgM and C3 was carried out for all cases. Sera were studied by standard indirect immunofluorescence, indirect immunofluorescence on salt-split skin, immunoblotting for bullous pemphigoid and mucous membrane pemphigoid and ELISA for pemphigus. With DIF, we found IgA autoantibodies in 22 of all 133 cases. Circulating IgA antibodies to skin were detected in 2 of 3 IgA-DIF-positive patients with pemphigus, in 3 of 6 with bullous pemphigoid, and in 6 of 13 with mucous membrane pemphigoid. We confirm that the IgA reactivity is more frequently associated with mucous membrane involvement, especially in cases without critical involvement (5/8). The role of IgA and its antigenic specificity in these diseases remain unclear. PMID:15370705

    Little detailed information is available on the association of Malassezia pachydermatis genotypes and the extent of skin damage that they cause. In the present study, isolates of M. pachydermatis, recovered from the skin of healthy dogs and dogs with dermatitis in Brazil, were characterized on the basis of partial sequencing of the large subunit (LSU), first internal transcribed spacer (ITS-1) and chitin synthase 2 gene (chs-2). The determination of phospholipase production was also included in the investigations. The severity of lesions and hyperpigmentation of dogs with skin disease were evaluated. For each locus, two main sequence types were designated as genotypes A and C. Two other minor sequence types (A2(I)-C2(I)) were also recorded and defined for the ITS-1. Genotype A isolates were the most prevalent, being recovered from healthy and diseased animals. No significant difference was detected among genotypes or ITS-1 sequence types and grades of skin damage or hyperpigmentation in the dogs with skin lesions. The number of M. pachydermatis isolates that produced phospholipase was statistically higher for diseased dogs than for strains found in healthy animals. The present study reveals that multiple genetic variants of M. pachydermatis occur in dogs and that the distribution patterns of particular genotypes on the skin of dogs in Brazil might be related to environmental and ecological factors which maintain distinctive genotype assemblages in specific geographical areas.

    The 53-year-old woman admitted with multiple persistent, progressive, slightly raised, red, and crusted plague form masses that suddenly occurred on left thumb, both upper and lower extremity about 10 years ago. There was no induration in the lesion or in its surrounding skin. There was no unusual opinion on a radiologic test and family history. And she had no history of working in the business related to any chemical product such as arsenic or tar which was carcinogen. The patient has had total hysterectomy to treat uterine myoma 10 years ago. The wide excision and split thickness skin graft of 2 × 1.5 cm was performed around mass in the size of 1.5 × 1.2 cm on the left thumb and wide excision and local advancement flap was done on the other sites. As a result of biopsy, masses were diagnosed as Bowen disease, actinic keratosis, and Seborrheic keratosis. These specimens were obtained during surgery: broom-type cell sampling devices were used to collect samples from the specimens, and they were placed into PreservCyt solution (Cytyc Corp, Boxborough, MA). Then, the collected samples underwent the Roche Linear Array HPV Genotyping Test (Roche Diagnostics, Branchburg, NJ) that allows for the simultaneous identification of human papilloma virus (HPV) types from liquid-based cell preparations. On histopathological examination of the surgical specimen, atypical squamous cells proliferate through the whole thickness of the epidermis. The entire tumor was confined to the epidermis and did not invade into the dermis. The cells were often highly atypical. That were the irregular shape which the resection margin of masses had a negative tumor component. And HPV 16 genotyping test was positive although vaginal examination of HPV 16 genotyping was negative. PMID:27192658

    Often people yearn of a greater travel adventure like a year in Africa to get away from their routine situations and locations, for a quick vacation or as a means of finding one's self, to enjoy new experiences, to learn and experience new languages, new food, and new cultures. While most people associate Sub-Saharan Africa with safaris, there are endless other possibilities for adventure. Some African countries have actual entry requirements and won't let you in unless you have proof you've been vaccinated against a specific disease. Every African country is unique in the quality of its parks and reserves, roads and other infrastructure, visitor accommodations and receptivity to tourists. Creating an itinerary and arranging travel logistics can intimidate even the most enthusiastic tourist. Others travel more nowadays for the better economy and the advancements in transportation make it easier to do so. If family members do not reside in the same country or are probably working abroad, other family members would want to visit them and would do so as frequently as their resources would allow. Visiting families and friends in different states or countries are probably the most important reasons for taking time off to travel. No doubt, travelling to different climates, cultures and environments abroad can expose to tropical infectious diseases and health risks. This review dealt with skin lesions in the returning travelers.

    Microphthalmia with linear skin lesions (MLS) is an X-linked dominant male-lethal disorder associated with mutations in holocytochrome c-type synthase (HCCS), which encodes a crucial player of the mitochondrial respiratory chain (MRC). Unlike other mitochondrial diseases, MLS is characterized by a well-recognizable neurodevelopmental phenotype. Interestingly, not all clinically diagnosed MLS cases have mutations in HCCS, thus suggesting genetic heterogeneity for this disorder. Among the possible candidates, we analyzed the X-linked COX7B and found deleterious de novo mutations in two simplex cases and a nonsense mutation, which segregates with the disease, in a familial case. COX7B encodes a poorly characterized structural subunit of cytochrome c oxidase (COX), the MRC complex IV. We demonstrated that COX7B is indispensable for COX assembly, COX activity, and mitochondrial respiration. Downregulation of the COX7B ortholog (cox7B) in medaka (Oryzias latipes) resulted in microcephaly and microphthalmia that recapitulated the MLS phenotype and demonstrated an essential function of complex IV activity in vertebrate CNS development. Our results indicate an evolutionary conserved role of the MRC complexes III and IV for the proper development of the CNS in vertebrates and uncover a group of mitochondrial diseases hallmarked by a developmental phenotype.

    Syphilis is commonly known as "the great imitator" owing to its varied clinical manifestations. Secondary syphilis has a variety of presentations, with the most common manifesting as a diffuse papulosquamous eruption on the palms and soles. Lues maligna praecox is a rare form of secondary syphilis, with severe constitutional symptoms, seen primarily in HIV-positive individuals. We report an atypical case of suspected lues maligna in a 45-year-old male. The patient was HIV-positive with a CD4 count of 441. He presented to our clinic with large painful gummatous ulcers in the groin and lower back. He also reported daily fevers, night sweats, and weight loss consistent with secondary syphilis. Prior to this episode the patient had a history of acute active syphilis (RPR 1:128) in 2012 treated at that time with a single dose of 2.4 million units intramuscular benzathine penicillin; he had no reported exposures since that time. The patient was treated with three weekly doses of benzathine penicillin, 2.4 million units, given intramuscularly. This case demonstrates the importance of recognizing the varied clinical presentation of secondary syphilis and keeping lues maligna in consideration for ulceronodular skin lesions in patients who are HIV-positive.

    Chronic arsenic (As) exposure affects the endothelial system causing several diseases. Big endothelin-1 (Big ET-1), the biological precursor of endothelin-1 (ET-1) is a more accurate indicator of the degree of activation of the endothelial system. Effect of As exposure on the plasma Big ET-1 levels and its physiological implications have not yet been documented. We evaluated plasma Big ET-1 levels and their relation to hypertension and skin lesions in As exposed individuals in Bangladesh. A total of 304 study subjects from the As-endemic and non-endemic areas in Bangladesh were recruited for this study. As concentrations in water, hair and nails were measured by Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The plasma Big ET-1 levels were measured using a one-step sandwich enzyme immunoassay kit. Significant increase in Big ET-1 levels were observed with the increasing concentrations of As in drinking water, hair and nails. Further, before and after adjusting with different covariates, plasma Big ET-1 levels were found to be significantly associated with the water, hair and nail As concentrations of the study subjects. Big ET-1 levels were also higher in the higher exposure groups compared to the lowest (reference) group. Interestingly, we observed that Big ET-1 levels were significantly higher in the hypertensive and skin lesion groups compared to the normotensive and without skin lesion counterpart, respectively of the study subjects in As-endemic areas. Thus, this study demonstrated a novel dose–response relationship between As exposure and plasma Big ET-1 levels indicating the possible involvement of plasma Big ET-1 levels in As-induced hypertension and skin lesions. -- Highlights: ► Plasma Big ET-1 is an indicator of endothelial damage. ► Plasma Big ET-1 level increases dose-dependently in arsenic exposed individuals. ► Study subjects in arsenic-endemic areas with hypertension have elevated Big ET-1 levels. ► Study subjects with arsenic

  2. Elevated levels of plasma Big endothelin-1 and its relation to hypertension and skin lesions in individuals exposed to arsenic

    International Nuclear Information System (INIS)

    Chronic arsenic (As) exposure affects the endothelial system causing several diseases. Big endothelin-1 (Big ET-1), the biological precursor of endothelin-1 (ET-1) is a more accurate indicator of the degree of activation of the endothelial system. Effect of As exposure on the plasma Big ET-1 levels and its physiological implications have not yet been documented. We evaluated plasma Big ET-1 levels and their relation to hypertension and skin lesions in As exposed individuals in Bangladesh. A total of 304 study subjects from the As-endemic and non-endemic areas in Bangladesh were recruited for this study. As concentrations in water, hair and nails were measured by Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The plasma Big ET-1 levels were measured using a one-step sandwich enzyme immunoassay kit. Significant increase in Big ET-1 levels were observed with the increasing concentrations of As in drinking water, hair and nails.

    Disseminated histoplasmosis is caused by the dimorphic fungus Histoplasma capsulatum (H. capsulatum). The early clinical manifestations are nonspecific, often lead to diagnostic difficulty, and is misdiagnosed as tuberculosis and seen usually in immunosuppressed states. Fine needle aspiration cytology (FNAC) is a simple, safe, and quick technique to establish the initial diagnosis of H. capsulatum, thereby prompting early treatment. The skin involvement is rare in disseminated disease and we describe a case of disseminated histoplasmosis in an immunocompetent patient with unusual molluscum contagiosum like umbilicated skin lesions and FNAC of the cervical lymph node was the only tool for rapid and early confirmatory diagnosis.

    Chronic hepatitis C might lead to several immunological dysfunctions. Studies have shown a positive association between hepatitis C virus (HCV) infection and psoriasis. These results suggest that the infection may be one of the triggering factors for the development or exacerbation of psoriasis. Here, we present a case of chronic HCV infection with psoriasis who developed exacerbation of skin lesions during therapy with peginterferon alpha-2a plus ribavirin. We discuss the management, course and results of HCV treatment in this patient.

    Lobomycosis is a chronic fungal disease caused by the etiologic agent, Lacazia loboi, in the skin and subcutaneous tissues in humans and dolphins in tropical and transitional tropical climates. An Indo-Pacific bottlenose dolphin (Tursiops aduncus) stranded in Kagoshima, Japan, had severe skin lesions characterized by granulomatous reactions and hyperkeratosis that were similar to those of the lobomycosis, but no fungal organism was observed in the skin lesion. In this paper, we report a stranded Indo-Pacific bottlenose dolphin with lobomycosis-like lesions based on pathological examinations in Japan.

    Xeroderma pigmentosum (XP), a rare hereditary syndrome, is characterized by a hypersensitivity to solar irradiation due to a defect in nucleotide excision repair resulting in a predisposition to squamous and basal cell carcinomas as well as malignant melanomas appearing at a very early age. The mutator phenotype of XP cells is evident by the higher levels of UV specific modifications found in key regulatory genes in XP skin tumors compared to those in the same tumor types from the normal population. Thus, XP provides a unique model for the study of unrepaired DNA lesions, mutations and skin carcinogenesis. The high level of ras oncogene activation, Ink4a-Arf and p53 tumor suppressor gene modifications as well as alterations of the different partners of the mitogenic sonic hedgehog signaling pathway (patched, smoothened and sonic hedgehog), characterized in XP skin tumors have clearly demonstrated the major role of the UV component of sunlight in the development of skin tumors. The majority of the mutations are C to T or tandem CC to TT UV signature transitions, occurring at bipyrimidine sequences, the specific targets of UV induced lesions. These characteristics are also found in the same genes modified in sporadic skin cancers but with lower frequencies confirming the validity of studying the XP model. The knowledge gained by studying XP tumors has given us a greater perception of the contribution of genetic predisposition to cancer as well as the consequences of the many alterations which modulate the activities of different genes affecting crucial pathways vital for maintaining cell homeostasis.

    One of the most challenging problems in clinical dermatology is the early detection of melanoma. Reflectance confocal microscopy (RCM) is an added tool to dermoscopy improving considerably diagnostic accuracy. However, diagnosis strongly depends on the experience of physicians. High-definition optical coherence tomography (HD-OCT) appears to offer additional structural and cellular information on melanocytic lesions complementary to that of RCM. However, the diagnostic potential of HD-OCT seems to be not high enough for ruling out the diagnosis of melanoma if based on morphology analysis. The aim of this paper is first to quantify in vivo optical properties such as light attenuation in melanocytic lesions by HD-OCT. The second objective is to determine the best critical value of these optical properties for melanoma diagnosis. The technique of semi-log plot whereby an exponential function becomes a straight line has been implemented on HD-OCT signals coming from four successive skin layers (epidermis, upper papillary dermis, deeper papillary dermis and superficial reticular dermis). This permitted the HD-OCT in vivo measurement of skin entrance signal (SES), relative attenuation factor normalized for the skin entrance signal (µ raf1) and half value layer (z 1/2). The diagnostic accuracy of HD-OCT for melanoma detection based on the optical properties, µ raf1 , SES and z 1/2 was high (95.6, 82.2 and 88.9 %, respectively). High negative predictive values could be found for these optical properties (96.7, 89.3 and 96.3 %, respectively) compared to morphologic assessment alone (89.9 %), reducing the risk of mistreating a malignant lesion to a more acceptable level (3.3 % instead of 11.1 %). HD-OCT seems to enable the combination of in vivo morphological analysis of cellular and 3-D micro-architectural structures with in vivo analysis of optical properties of tissue scatterers in melanocytic lesions. In vivo HD-OCT analysis of optical properties permits melanoma

  12. Skin lesions in European hibernating bats associated with Geomyces destructans, the etiologic agent of white-nose syndrome.

    Full Text Available White-nose syndrome (WNS has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesions that are the hallmark of the disease. The fungal infection is characterized by a white powdery growth on muzzle, ears and wing membranes. While WNS may threaten some species of North American bats with regional extinction, infection in hibernating bats in Europe seems not to be associated with significant mortality. We performed histopathological investigations on biopsy samples of 11 hibernating European bats, originating from 4 different countries, colonized by G. destructans. One additional bat was euthanized to allow thorough examination of multiple strips of its wing membranes. Molecular analyses of touch imprints, swabs and skin samples confirmed that fungal structures were G. destructans. Additionally, archived field notes on hibernacula monitoring data in the Harz Mountains, Germany, over an 11-year period (2000-2011 revealed multiple capture-recapture events of 8 banded bats repeatedly displaying characteristic fungal colonization. Skin lesions of G. destructans-affected hibernating European bats are intriguingly similar to the epidermal lesions described in North American bats. Nevertheless, deep invasion of fungal hyphae into the dermal connective tissue with resulting ulceration like in North American bats was not observed in the biopsy samples of European bats; all lesions found were restricted to the layers of the epidermis and its adnexae. Two bats had mild epidermal cupping erosions as described for North American bats. The possible mechanisms for any difference in outcomes of G. destructans infection in European and North American bats still need to be elucidated.

    Full Text Available We examined whether Angelicae Dahuricae Radix (AR suppresses the development of atopic dermatitis (AD-like skin lesions induced by Dermatophagoides farinae in NC/Nga mice. To investigate the effect of AR, we measured the AD severity score, measured plasma levels of IgE and histamine, and performed histological analysis in NC/Nga mice. We also confirmed the anti-inflammatory effects of AR by measuring TARC/CCL17 production from LPS-treated RAW 264.7 cells and mRNA levels of TARC and MDC/CCL22 in TNF-α/IFN-γ-treated HaCaT cells. 10 mg/day of AR extract was applied for 4 weeks to NC/Nga mice. Both the AR extract and 0.1% tacrolimus suppressed the development of AD-like skin lesions and reduced dermatitis scores of the back and ear skin. AR extracts caused an inhibition of histological changes induced by repeated application of D. farinae and a reduction of IgE and histamine levels in plasma (P<0.05. Furthermore, NO production in LPS-treated RAW 264.7 cells was diminished in a dose-dependent manner, and hTARC production and TARC and MDC mRNA levels in TNF-α/IFN-γ-treated HaCaT cells were diminished by AR. The inhibitory effect of AR on NO, TARC and MDC production may be associated with the suppression of AD-like skin lesions in D. farinae-induced NC/Nga mice.

    Tonsillar infection with Streptococcus pyogenes may induce several nonsuppurative autoimmune sequelae. The precise pathogenetic mechanisms behind this clinically well-established association are still unresolved. Using TCR analysis, we sought to identify a link between streptococcal tonsillitis and the T cell-mediated autoimmune response in psoriasis. Three patients with streptococcal-induced psoriasis underwent tonsillectomy. Using size spectratyping and sequencing of TCR beta-chain variable region gene (TCRBV) rearrangements, we compared the TCR usage of psoriatic skin lesions, blood, tonsils, and tonsillar T cells fractionated according to the expression of the skin address in "cutaneous lymphocyte-associated Ag" (CLA). TCRBV-size spectratype analysis of the blood lymphocytes, tonsils, and the CLA-negative tonsillar T cells revealed largely unselected T cell populations. Instead, TCRBV gene families of the psoriatic lesions and skin-homing CLA-positive tonsillar T cells displayed highly restricted spectratypes. Sequencing of TCRBV cDNA identified various clonal TCRBV rearrangements within the psoriatic lesions that indicated Ag-driven T cell expansion. Several of these clonotypes were also detected within the tonsils and, in one of the patients, within the small subset of CLA-positive tonsillar T cells, suggesting that T cells from the same T cell clones were simultaneously present within skin and tonsillar tissue. Because after tonsillectomy psoriasis cleared in all three patients our observations indicate that T cells may connect psoriatic inflammation to streptococcal angina. They suggest that the chronic streptococcal immune stimulus within the tonsils could act as a source for pathogenic T cells in poststreptococcal disorders, and they may help to explain why eliminating this source with tonsillectomy may improve streptococcal-induced sequelae.

    A 75-year-old man presented with a blistering skin disease and nephrotic syndrome. Bullous pemphigoid was diagnosed by linear immunoglobulin G (IgG) and C3 staining along the basement membrane zone of a skin biopsy specimen and by the presence of circulating IgG recognizing the 180-kDa bullous pemphigoid antigen (BP180; type XVII collagen). A kidney biopsy specimen showed endocapillary inflammation without crescents. Direct immunofluorescence showed strong IgG and C3 staining in a combined granular and linear pattern along the glomerular basement membrane. Electron microscopy showed subepithelial deposits. In serum, no antibodies against the Goodpasture antigen (type IV collagen) or phospholipase A2 receptor were detected. Indirect immunofluorescence studies using the patient's serum showed a strikingly linear but not granular IgG pattern along the epithelial basement membranes of monkey esophagus and kidney. Although type XVII collagen was recently identified in the glomerulus, the patient's serum did not produce a 180-kDa band on immunoblot of kidney tissue and still stained glomeruli of BP180 knockout mice by indirect immunofluorescence. The patient was treated with prednisone and azathioprine, which resulted in complete remission of skin and kidney manifestations. Although bullous pemphigoid has been reported previously in association with anti-glomerular basement membrane disease or membranous nephropathy, this case demonstrates both elements in 1 patient. This concurrence and the linear pattern on indirect immunofluorescence support the possibility of cross-reactive or parallel autoantibodies to basement membranes with a secondary membranous component.

    We evaluated the anti-atopic dermatitis (AD) effect of Atofreellage (AF), a herbal formula composed of 10 medicinal plants. AD was induced on the dorsal skin areas of NC/Nga mice (male, seven weeks old) by daily application of 2,4-dinitrochlorobenzene (DNCB) for five weeks. After three weeks of DNCB application, 200 μL of AF (0, 25, 50 or 100 mg/mL) was applied to the skin lesions. Histological findings, blood cell populations, serum levels of immunoglobulin E (IgE), histamine, pro-inflammatory cytokines, and inflammatory signaling in the skin tissue, and T-helper cell type 2 (Th₂)-related cytokines in splenocytes were analyzed. Histopathological findings showed AF treatment notably attenuated the thickness of dorsal skin, and eosinophil infiltration. AF treatment (especially 100 mg/mL) also demonstrably ameliorated the blood cell population abnormalities, as the notable elevation of serum concentrations of IgE, histamine, TNF-α, IL-6 and IL-1β were remarkably normalized by AF treatment. Western blot analysis evidenced the apparent normalization of inflammatory signals (ERK, p38 MAP kinase, JNK, and NF-κB) in the skin tissue. Additionally, AF treatment notably attenuated the activation of Th₂-dominant cytokines (IL-13, IL-4, and IL-5) in Con A-treated splenocytes in an ex vivo assay. In conclusion, this study provides experimental evidence for the clinical relevance of Atofreellage. PMID:26712731

    Oranges are suspected of inducing adverse skin reactions in patients with atopic eczema. We studied 21 adult patients with atopic eczema and a history of adverse reactions to oranges and 10 patients without. A dietary history, skin tests, serum IgE and oral provocation tests with oranges were obtained. Severity of eczema was monitored by SCORAD, and serum tryptase, eosinophil cationic protein and urinary methylhistamine were measured. No allergic reactions were found to orange in skin prick or patch tests. However, 23 patients (74%) had specific serum IgE to orange. Oral provocation testing resulted in pruritic eczematous or maculopapular skin lesions predominantly at the predilection sites in 16 patients (52%). The SCORAD increased significantly in patients positive to the oral provocation test (p orange did not correlate with the clinical outcome of the oral provocation test. No significant changes were found in serum mast cell tryptase, eosinophil cationic protein or in urinary methylhistamine excretion. The negative results in the skin tests and a lack of correlation between specific IgE and oral provocation tests indicate that non-IgE-mediated mechanisms are involved in cutaneous adverse reactions to oranges in patients with atopic eczema.

    Growing pigs can display undesirable behaviours, reflecting or causing poor welfare. Addition of magnesium (Mg) to the diet could reduce these, as Mg supplementation has been associated with improved coping ability in response to stress. This study examined the effect of supplementation with a Mg-rich marine extract-based product (Supplement) on the behaviour, skin and tail lesion scores and salivary cortisol concentrations of growing pigs. At weaning (28 days), 448 piglets were assigned to either Control or Supplement (0.05%) diets in single-sex groups of 14. Four weeks later (c. 17 kg), pigs were blocked according to weight and back test scores. Seven piglets from each pen were mixed with seven from another pen of the same sex and dietary treatment to yield the following groups: control male, Supplement male, control female and Supplement female (n = 4 of each). This marked the start of the 9-week experimental period. Instances of the following behaviours were recorded in each pen for 8 × 2 min periods 1 day/week: aggression (fight, head-knock and bite); harmful (tail-in-mouth, ear-chewing and belly-nosing); and sexual/mounting behaviour. Four focal pigs were selected from each pen, and their behaviour was continuously recorded for 2 × 5 min periods on the same day. Saliva was collected once per week at 1000 h by allowing pigs to chew on a cotton bud for c. 1 min. Salivary cortisol was analysed in duplicate by an enzyme immunoassay. Skin and tail lesions were scored according to severity 1 day/week. There were fewer aggressive incidents in Supplement pens (P pigs showed no treatment effect on the duration or incidence of aggressive behaviour. However, Supplement pigs spent less time performing harmful behaviours compared with control pigs (P tail-biting outbreaks or on tail lesion scores. However, Supplement females had lower skin lesion scores, in particular in the ears and shoulders (P pigs had lower salivary cortisol concentrations (P pigs, and therefore

    Full Text Available Kimura′s disease is characterized by a triad of painless subcutaneous masses, eosinophilia in the peripheral blood and in tissues with marked increase in Serum Ig E. Angiolymphoid hyperplasia with eosinophilia (ALHE manifests with the presence of dermal papules and nodules. Unique clinical, histopathological, and biochemical findings are noted in these individual entities. A 32-year-female presented with multiple nodules in the axillae for 2 years. Peripheral smear showed eosinophilia with AEC of 6080. Histopathological examination showed features of overlap. Antinuclear antibody immunoflorescence was was negative. CD31, CD34, and FVIII were positive in vascular component. A CT chest revealed left axillary lymphadenopathy. The patient was treated with Cryotherapy and there was complete regression of skin lesions, with no recurrence after 1 year of follow-up. ALHE and KD are common in the head and neck region, but no reports of an overlap, presenting with lesions in the axillae are available to date, to the best of our knowledge. Response of skin lesions to cryotherapy is highlighted.

    Psoralen plus ultraviolet A radiation (PUVA) therapy is a very important clinical treatment of skin diseases such as vitiligo and psoriasis, but associated with an increased risk of skin photodamage, especially photoaging. In this work, optical coherence tomography (OCT), a novel non-invasive imaging technology, was introduced to investigate in vivo the photodamage induced by PUVA qualitatively and quantitatively. Balb/c mouse dorsal skin was treated with 8-methoxypsoralen (8-MOP), and then exposed to UVA radiation. OCT images of the tissues were obtained by an OCT system with a 1310 nm central wavelength. Skin thickness and the attenuation coefficient were extracted from the OCT images to analyze the degree of injury to mouse skin. The results demonstrated that PUVA-treated skin showed an increase in skin thickness, and a reduction of attenuation coefficient in the OCT signal compared with the control groups. The data also showed good correlation with the results observed in histological sections using hematoxylin and eosin staining. In conclusion, OCT is a promising tool for photobiological studies aimed at assessing the effect of PUVA therapy in vivo.

    Full Text Available Atopic dermatitis (AD is a common inflammatory skin disease. The increasing prevalence and severity of AD have prompted the developments of safer, more effective drugs. Although topical corticosteroids have been used as first line therapy for AD, their potential side effects limit their clinical applications. To investigate the effect of hirsutenone (HIR, a diarylheptanoid compound, on AD-like skin lesions and other factors related to immune response is the aim of this paper Th2-related cytokines (IL-4, IL-5, IL-13, eosinophil, IgE inflammatory factors (COX-2, iNOS levels were reduced in blood, lymphocytes, and tissue after HIR treatment. These results suggest that HIR might be an effective treatment for AD.

    Toxic epidermal necrolysis is a rare but clinically well-described dermatological pathology. However, clinical pictures of this disorder in text books do not reflect its dynamic evolution. Usually, the desquamative post-bullous stage is represented, neglecting the initial bullous stage as well as the skin healing. With one clinical case, we provide a day-after-day illustration of the evolution of a patient suffering from toxic epidermal necrolysis. During one month, a skin area of a limb was ...

    Full Text Available Abstract Background Yaws is a bacterial skin and bone infectious disease caused by Treponema pallidum pertenue. It is endemic, particularly among pygmies in Central African Republic. To assess the clinical cure rate after treatment with benzathinepenicillin in this population, we conducted a cohort survey of 243 patients in the Lobaye region. Findings and conclusion The rate of healing of lesions after 5 months was 95.9%. This relatively satisfactory level of therapeutic response implies that yaws could be controlled in the Central African Republic. Thus, reinforcement of the management of new cases and of contacts is suggested.

  8. Amorphous silica nanoparticles size-dependently aggravate atopic dermatitis-like skin lesions following an intradermal injection

    2012-02-01

    Full Text Available Abstract Background Due to the rising use of nanomaterials (NMs, there is concern that NMs induce undesirable biological effects because of their unique physicochemical properties. Recently, we reported that amorphous silica nanoparticles (nSPs, which are one of the most widely used NMs, can penetrate the skin barrier and induce various biological effects, including an immune-modulating effect. Thus, it should be clarified whether nSPs can be a risk factor for the aggravation of skin immune diseases. Thus, in this study, we investigated the relationship between the size of SPs and adjuvant activity using a model for atopic dermatitis. Results We investigated the effects of nSPs on the AD induced by intradermaly injected-mite antigen Dermatophagoides pteronyssinus (Dp in NC/Nga mice. Ear thickness measurements and histopathological analysis revealed that a combined injection of amorphous silica particles (SPs and Dp induced aggravation of AD in an SP size-dependent manner compared to that of Dp alone. In particular, aggravation was observed remarkably in nSP-injected groups. Furthermore, these effects were correlated with the excessive induction of total IgE and a stronger systemic Th2 response. We demonstrated that these results are associated with the induction of IL-18 and thymic stromal lymphopoietin (TSLP in the skin lesions. Conclusions A particle size reduction in silica particles enhanced IL-18 and TSLP production, which leads to systemic Th2 response and aggravation of AD-like skin lesions as induced by Dp antigen treatment. We believe that appropriate regulation of nanoparticle physicochemical properties, including sizes, is a critical determinant for the design of safer forms of NMs.

  9. Toward noninvasive microspectrofluorometry of skin lesions for diagnostic and prognostic evaluation of cell metabolism and organelle interactions

    The basic principle of this approach relies on microspectrofluorometric observations of upheavals in the cell's energy metabolism and cell-to-cell metabolic communication in human and mouse melanoma cells. A striking feature is the definition of a highly active nuclear energy metabolism in M8255 human melanoma cells which is characterized by an intense fluorescence response associated with NAD(P) reduction by substrates of glycolysis or the hexose monophosphate shunt. Changes are also expected in the steady state levels of reduced/oxidized NAD(P) in the nuclear, cytoplasmic and mitochondrial compartments, which are probably dependent on ATP levels and distribution (as determined by cell metabolism and eventually the presence of ATP traps). A topographic scanning of skin lesions, either under metabolic steady state conditions or in the presence of permeating substrates, can lead to the recognition of characteristic patterns associated with pigmented and nonpigmented, malignant and nonmalignant skin lesions. The method is, in a way, an extension of microscopic transillumination techniques which have led to the identification of specific patterns associated with such lesions. However, here, a new dimension is added by introduction of fluorescence evaluations. This can represent the first step in a multiparameter approach to the non-invasive in situ fluorescence scan of dermatological lesions by inclusion of: (1) fluorescence excitation and emission spectra; (2) new fluorescence probes of cytoplasmic organelles and nuclear components. Primary emphasis should be placed on the highly active nuclear energy metabolism, which can be triggered to maximum levels when the role of mitochondria as the `cells's policeman' with regard to metabolic control is suppressed by use of topically cytotoxic agents such as the `antipsoriatic' anthralin and dicarboxylic acids used in the local treatment of melanoma. Fluorescence excitation spectroscopy may be of particular advantage in

    2013-01-01

    It was previously demonstrated that the main cause behind keloid formation may be keloid fibroblast abnormalities, which are closely associated with the microenvironment of the keloid lesion. The post-traumatic and chronic inflammation of the keloid lesion area suggest that inflammatory mediators play an important role in the keloid microenvironment and are crucial for keloid fibroblast abnormalities. In this study, we hypothesized that the mechanism underlying keloid formation may involve th...

    Full Text Available The nature of association between Demodex mites and bacteria involved in bovine demodectic mange lesions and the normal flora inhabiting the skin of noninfected animals was investigated. Demodex bovis and D. ghanensis mites were isolated from the infected purulent material extracted from skin and meibomian gland lesions, respectively. The mites could not be demonstrated in skin brushings or impression smears from the eyes of noninfected cattle. Pathogenic bacteria (Staphylococcus aureus and Streptococcus pyogenes (Group A and opportunistic organisms (Proteus vulgaris, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Trueperella pyogenes were isolated from skin lesions of demodectic mange, and Moraxella bovis and Staphylococcus aureus were isolated from meibomian gland lesions. Bacillus subtilis, Escherichia coli, Proteus vulgaris, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes (Group A were isolated from skin brushings from noninfected cattle. The nature of association between Demodex mites and bacteria in demodectic mange lesions is synergistic and of equal significance. Pathogenic and opportunistic bacteria facilitated the establishment of Demodex mites in the lesions produced and provided an excellent microclimate for the mites to propagate and reproduce, resulting in severe and progressive disease. The “high-turnover” granulomatous reaction which characterized the histopathological changes proved that Demodex mites and associated bacteria were persistent and immunogenic.

    Full Text Available Puffy hand syndrome develops after long-term intravenous drug addiction. It is characterized by a nonpitting edema, affecting the dorsal side of fingers and hands with puffy aspect. Frequency and severity of the complications of this syndrome are rarely reported. Local infectious complications such as cellulitis can be severe and can enable the diagnosis. Herein, we report the case of a 41-year-old man who went to the emergency department for abdominal pain, fever, and bullous lesions of legs and arms with edema. Bacteriologic examination of a closed bullous lesion evidenced a methicillin sensitive Staphylococcus aureus. The abdomen computed tomography excluded deep infections and peritoneal effusion. The patient was successfully treated by intravenous oxacillin and clindamycin. He had a previous history of intravenous heroin addiction. We retained the diagnosis of puffy hand syndrome revealed by a severe staphylococcal infection with toxic involvement mimicking a four limbs cellulitis. Puffy hand syndrome, apart from the chronic lymphedema treatment, has no specific medication available. Prophylactic measures against skin infections are essential.

    . Spectrophotometric intracutaneous analysis (SIAscopy) is a new, commercially available method of analyzing pigmented skin lesions noninvasively. The diagnosis is based on objective features such as the presence of dermal pigment, vascularity of the lesion, and the integrity of collagen. The objective of this study......Dermoscopy is considered to be the golden standard for the clinical assessment of pigmented skin lesions. In expert hands, this instrument improves both sensitivity and specificity for the diagnosis of melanoma, however, the outcome is highly dependent on the skills and experience of the examiner....... The specificity of dermoscopy in this study was 81% against 59% for SIAscopy. Our result shows that dermoscopy remains the best diagnostic tool for the preoperative diagnosis of pigmented skin lesions. However, as the SIAscope in addition to the SIAgraph images produces dermoscopic images, it holds the advantages...

    Psoriasis is an inflammatory skin disease characterized by excessive proliferation and abnormal differentiation and apoptosis of keratinocytes (KCs). Mesenchymal stem cells (MSCs) from skin lesions of psoriasis patients demonstrate abnormal cytokine secretion, which may affect KC proliferation and apoptosis. Here, we explored how MSCs from skin lesions of psoriasis patients affect HaCaT cell proliferation and apoptosis. First, flow cytometry and multipotent differentiation methods were used to identify skin MSCs, which were then co-cultured with HaCaT cells. HaCaT cell proliferation was analyzed in real-time, and cell cycle progression and apoptosis were assessed by flow cytometry. Cell morphologies and multipotencies of skin MSCs were similar between the psoriasis group and healthy control group, with high levels of CD29, CD44, CD73, CD90, and CD105 and limited expression of CD34, CD45, and HLA-DR. MSCs from skin lesions of psoriasis patients promote KC proliferation more potently and are less capable of inducing KC apoptosis. This may underlie KC proliferation and abnormal apoptosis in psoriasis skin lesions, which results in abnormal thickening of the epidermis.

    To determine the occurrence of hereditary bullous epidermolyses (EB) in Croatia, Yugoslavia, from 1960 to 1987, cases were gathered from the hospital files of dermatologic and pediatric clinics and departments throughout the area. The diagnosis of EB type was made on the basis of clinical features, patients' histories, and light microscopy and electron microscopy findings. Fifty families with 58 patients were registered; 44 patients were examined personally by one of the authors. The most frequent type of EB in Croatia was recessive dystrophic EB Hallopeau-Siemens, occurring in 35 of the 58 individuals. Regional accumulation of cases within the Varazdin area was noted (13 patients). Prevalence of EB in Croatia is 0.956 cases per 100,000 inhabitants. One case of recessive dystrophic EB Hallopeau-Siemens occurred in about every 52,000 live births.

    Full Text Available We investigated the bacterial flora present in skin lesions of patients with chiclero's ulcer from the Yucatan peninsula of Mexico using conventional culture methods (11 patients, and an immunocolorimetric detection of pathogenic Streptococcus pyogenes (15 patients. Prevalence of bacteria isolated by culture methods was 90.9% (10/11. We cultured, from chiclero's ulcers (60%, pathogenic bacterial such as Staphylococcus aureus (20%, S. pyogenes (1.6%, Pseudomonas aeruginosa (1.6%, Morganella morganii (1.6%, and opportunist pathogenic bacteria such as Klebsiella spp. (20.0%, Enterobacter spp. (20%, and Enterococcus spp. (20%. We also cultured coagulase-negative staphylococci in 40% (4/10 of the remaining patients. Micrococcus spp. and coagulase-negative staphylococci constituted the bacterial genuses more frequently isolated in the normal skin of patients with chiclero's ulcer and healthy individuals used as controls. We also undertook another study to find out the presence of S. pyogenes by an immunocolorimetric assay. This study indicated that 60% (9/15 of the ulcerated lesions, but not normal controls, were contaminated with S. pyogenes. Importantly, individuals with purulent secretion and holding concomitant infections with S. pyogenes, S. aureus, P. aeruginosa, M. morganii, and E. durans took longer to heal Leishmania (L. mexicana infections treated with antimonial drugs. Our results suggest the need to eliminate bacterial purulent infections, by antibiotic treatment, before starting antimonial administration to patients with chiclero's ulcer.

    Rubber mats covering concrete slatted flooring are a developing market in dairy barns but remain rare in beef cattle facilities. The aim of this study was to investigate the effects of covering slatted concrete floor with perforated rubber mats on behaviour and occurrence of skin and claw lesions in fattening bulls. The groups of six bulls each with a total average age of 9.8 months were kept over 1 year on either slatted concrete (CONCRETE PEN) or on slatted concrete covered completely (RUBBER PEN) or partially (CHOICE PEN) with perforated rubber mats. Every quarter-year, behaviour (preference of flooring, lying, aggression, mounting) was recorded. In two-weekly intervals the incidence of skin lesions was examined. At 12 and 18 months of age the rising time of the bulls was measured. At the beginning of the study and after slaughter claw dimensions were recorded. Bulls in the CHOICE PEN preferred (PCONCRETE PEN. Bulls in the CHOICE PEN needed less time for rising (2.7+/-0.3s) than bulls in the CONCRETE PEN (4.4+/-0.5s, PCHOICE>CONCRETE; Pflooring has a positive influence on the housing conditions of beef cattle.

    The biofield breast examination (BBE) is a new, noninvasive and cost-effective method for diagnosing breast lesions currently undergoing multicenter evaluation in the USA and Europe. The test analyzes subtle differences in electrical potential caused by dysregulated epithelial proliferation. This report summarizes a prospective evaluation of BBE in a population of 101 patients with suspicious breast lesions scheduled either for open surgical biopsy or fine needle aspiration biopsy. Of the 101 patients included in the study, 49 were found to have a breast malignancy and 52 were found to have a benign breast lesion. BBE correctly identified 44 of 49 biopsy-proven cancers (sensitivity=90%) and correctly indicated no cancer in 31 of 52 biopsy-proven benign cases (specificity=60%). Sensitivity increased to 95% for cancers less than 2.5 cm in size. These results indicate that BBE may be an effective adjunctive test to help to resolve abnormalities discovered by physical examination or other screening methods.

    Full Text Available Papillomavirus was detected electron microscopically in cutaneous fibropapillomas of a giraffe (Giraffa camelopardalis and a sable antelope (Hippotragus niger. The virus particles measured 45 nm in diameter. Histopathologically, the lesions showed histopathological features similar to those of equine sarcoid as well as positive immunoperoxidase-staining of tissue sections for papillomavirus antigen. Polymerase chain reaction (PCR detected bovine papillomavirus (BPV DNA. Bovine papillomavirus-1 was characterised by real-time PCR in the sable and giraffe, and cloning and sequencing of the PCR product revealed a similarity to BPV-1. As in the 1st giraffe, the lesions from a 2nd giraffe revealed locally malignant pleomorphism, possibly indicating the lesional end-point of papilloma infection. Neither virus particles nor positively staining papillomavirus antigen could be demonstrated in the 2nd giraffe but papillomavirus DNA was detected by real-time PCR which corresponded with BPV-1 and BPV-2.

    The cell stress chaperone heat shock protein 90 (Hsp90) has been implicated in inflammatory responses and its inhibition has proven successful in different mouse models of autoimmune diseases, including epidermolysis bullosa acquisita. Here, we investigated expression levels and secretory responses of Hsp90 in patients with bullous pemphigoid (BP), the most common subepidermal autoimmune blistering skin disease. In comparison to healthy controls, the following observations were made: (i) Hsp90 was highly expressed in the skin of BP patients, whereas its serum levels were decreased and inversely associated with IgG autoantibody levels against the NC16A immunodominant region of the BP180 autoantigen, (ii) in contrast, neither aberrant levels of circulating Hsp90 nor any correlation of this protein with serum autoantibodies was found in a control cohort of autoimmune bullous disease patients with pemphigus vulgaris, (iii) Hsp90 was highly expressed in and restrictedly released from peripheral blood mononuclear cells of BP patients, and (iv) Hsp90 was potently induced in and restrictedly secreted from human keratinocyte (HaCaT) cells by BP serum and isolated anti-BP180 NC16A IgG autoantibodies, respectively. Our results reveal an upregulated Hsp90 expression at the site of inflammation and an autoantibody-mediated dysregulation of the intracellular and extracellular distribution of this chaperone in BP patients. These findings suggest that Hsp90 may play a pathophysiological role and represent a novel potential treatment target in BP. PMID:23936217

    Full Text Available Cyclins play a fundamental role in the cell cycle. Recent studies have focused on their role in the development of various malignancies. The objective of this study was to evaluate and compare the expression of cyclins A and E in common nevi, dysplastic nevi and malignant melanomas, and to investigate the relationship between cyclin expression and some pathological parameters such as tumor thickness, ulceration, regression, and mitotic rate, as well as several clinical and phenotypic parameters such as skin phototype, hair and eye color, number of nevi, personal or family melanoma history, and personal history of nonmelanoma skin cancer (NMSC. A total of 102 melanocytic skin lesions, including 30 common nevi, 38 dysplastic nevi and 34 melanomas, were examined. Expression of cyclins was detected by immunohistochemistry and quantified as a percentage of immunostained cell nuclei in each sample. Significant differences in expression of both cyclins were found between all lesion types: the median percentage of cyclin A-positive nuclei was 8.2% in melanomas, 3.4% in dysplastic nevi, and 0.95% in common nevi (p < 0.001. The corresponding percentages for cyclin E were 9.5%, 4.25% and 1.44% (p < 0.001. Expression of both cyclins was significantly higher among patients with a personal history of NMSC. Cyclin A was also significantly overexpressed in patients with a high total nevus count (TNC compared to moderate and low TNC. Expression of cyclins did not significantly correlate with the other clinicopathologic features investigated. These findings indicate the possible involvement of cyclins A and E in the pathogenesis of malignant melanoma. Our results also show a potential diagnostic significance of these cyclins as markers allowing discrimination between dysplastic nevi and melanoma.

    Introduction. To minimize delay between presentation, diagnosis, and treatment of cutaneous melanoma (CM), a national fast-track referral system (FTRS) was implemented in Denmark. The aim of this study was to analyze the referral patterns to our department of skin lesions suspicious of melanoma in the FTRS. Methods. Patients referred to the Department of Plastic Surgery and Breast Surgery in Zealand University Hospital were registered prospectively over a 1-year period in 2014. A cross-sectional study was performed analyzing referral patterns, including patient and tumor characteristics. Results. A total of 556 patients were registered as referred to the center in the FTRS for skin lesions suspicious of melanoma. Among these, a total of 312 patients (56.1%) were diagnosed with CM. Additionally, 41 (7.4%) of the referred patients were diagnosed with in situ melanoma. Conclusion. In total, 353 (63.5%) patients had a malignant or premalignant melanocytic skin lesion. When only considering patients who where referred without a biopsy, the diagnostic accuracy for GPs and dermatologists was 29% and 45%, respectively. We suggest that efforts of adequate training for the referring physicians in diagnosing melanocytic skin lesions will increase diagnostic accuracy, leading to larger capacity in secondary care for the required treatment of malignant skin lesions.

    A 72-year-old woman with a 14-year history of urticarial vasculitis (UV) and a 13-year history of bullous pemphigoid (BP) presented with associated progressive chronic lymphocytic leukaemia (CLL). Both skin conditions responded poorly to treatment, until chemotherapy for CLL was commenced. The skin features showed a clear paraneoplastic course, resolving with chemotherapy and recurring when the CLL relapsed and the lymphocyte count rose above 5 × 10(9)/L. No case of UV secondary to CLL, and very few cases of BP related to CLL have been reported, and no paraneoplastic rash of any type lasting 14 years has been reported previously. PMID:25524180

    Allergic dermatitis among common skin diseases is a chronic and recurrent inflammatory skin disorder caused by genetic, environmental, allergens as well as microbial factors. Allergic dermatitis patients clinically present skin erythematous plaques, eruption, elevated serum immunoglobulin E (IgE) and T helper cell type 2 (Th2) cytokine levels. The leaf of walnut tree Juglans mandshurica Maxim (JM) is consumed food and traditional phytomedicine in Asia, China, Siberia and Korea. JM has been reported to have various pharmacological activities, such as anti-tumor, anti-oxidative, and anti-bacterial effects. However, no study of the inhibitory effects of JM on allergic dermatitis has been reported. Here, we demonstrated the effect of JM against 2,4-dinitrochlorobenzene-induced allergic dermatitis-like skin lesions. 0.5% JM or 1% dexamethasone (positive control) applied to the dorsal skin inhibited development of allergic dermatitis-like skin lesions and scratching behavior. Moreover, the Th2-mediated inflammatory cytokines IgE, tumor necrosis factor-α, interleukin (IL)-1, and IL-13, were significantly reduced by JM treatment. Thus JM can inhibit development of allergic dermatitis-like skin lesions in mice by regulating immune mediators, and may be an effective alternative therapy for allergic dermatitis.

    Valencene (VAL) isolated from Cyperus rotundus possesses various biological effects such as antiallergic and antimelanogenesis activity. We investigated the effect of VAL on atopic dermatitis (AD) skin lesions and their molecular mechanisms. We topically applied VAL to 1-chloro-2,4-dinitrobenzene (DNCB) sensitized NC/Nga mice. Modified scoring atopic dermatitis index, scratching behavior, and histological/immunohistochemical staining were used to monitor disease severity. RT-PCR, western blotting, and enzyme-linked immunosorbent assay were used to determine the level of IgE, proinflammatory cytokines/chemokines production, and skin barrier proteins expression. Topical application of VAL significantly reduced AD-like symptoms and recovered decreased expression of filaggrin in DNCB-sensitized NC/Nga mice. The levels of serum IgE, IL-1β, IL-6, and IL-13 in skin/splenic tissue were reduced. In vitro studies using TNF-α and IFN-γ treated HaCaT cells revealed that VAL inhibited the exaggerated expression of Th2 chemokines including TARC/CCL17, MDC/CCL22, and proinflammatory chemokines such as CXCL8, GM-CSF, and I-CAM through blockade of the NF-κB pathway. In addition, expression of the skin barrier protein, involucrin, was also increased by VAL treatment. VAL inhibited the production and expression of proinflammatory cytokines IL-1β and IL-6 in LPS-stimulated RAW 264.7 cells. These results suggest that VAL may serve as a potential therapeutic option for AD. PMID:27630735

    We use the wavelet-based decomposition to generate the multiresolution representation of dermatoscopic images of potentially malignant pigmented lesions. Three different machine learning methods are experimentally applied, namely neural networks, support vector machines, and Attributional Calculus. The obtained results confirm that neighborhood properties of pixels in dermatoscopic images are a sensitive probe of the melanoma progression and together with the selected machine learning methods may be an important diagnostic tool.

    The skin lesion of early Lyme disease, erythema migrans (EM), is so characteristic that routine practice is to treat all such patients with antibiotics. Because other skin lesions may resemble EM, it is not known whether presumptive treatment of EM is appropriate in regions where Lyme disease is rare. We constructed a decision model to compare the cost and clinical effectiveness of three strategies for the management of EM: Treat All, Observe, and Serology as a function of the probability that an EM-like lesion is Lyme disease. Treat All was found to be the preferred strategy in regions that are endemic for Lyme disease. Where Lyme disease is rare, Observe is the preferred strategy, as presumptive treatment would be expected to produce excessive harm and increased costs. Where Lyme disease is rare, clinicians and public health officials should consider observing patients with EM-like lesions who lack travel to Lyme disease-endemic areas.

    Full Text Available Histopathologic interpretation of dermoscopic and reflectance confocal microscopy (RCM features of cutaneous melanoma was timidly carried out using perpendicular histologic sections, which does not mimic the same plane of the image achieved at both techniques (horizontal plane. The aim of this study was to describe the transverse histologic sections research technique and correlate main dermoscopic features characteristic of cutaneous melanoma (atypical network, irregular globules and pseudopods with RCM and histopathology in perpendicular and transverse sections in order to offer a more precise interpretation of in vivo detectable features. Four melanomas and 2 nevi with different dermoscopic clues have been studied. Lesion areas that showed characteristic dermoscopic features were imaged by dermoscopy and confocal microscopy and directly correlated with histopathology in perpendicular and transverse sections. We presented the possibility to perform transverse sections as a new approach to understand RCM features. Atypical network showed different aspects in the 2 melanomas: in one case it was characterized by pleomorphic malignant melanocytes with tendency to form aggregates, whereas in the other elongated dendritic cells crowded around dermal papillae, some of them forming bridges that resembled the mitochondrial aspect at confocal and histopathology transversal sections. Pigment globules in melanomas and nevi differed for the presence of large atypical cells in the former, and pseudopods showed up as elongated nests protruded toward the periphery of the lesion. Transverse histologic research sections have a consistent dermoscopic and confocal correlate, and it may represent an help in confocal feature interpretation and an advance in improving melanoma diagnosis and knowledge of the biology of melanocytic lesions.

    Peptide T has been shown to be an effective treatment in psoriasis. The mechanism through which peptide T works in psoriasis is at present unknown. Furthermore, a clearance of psoriasis has also been registered using the inhibitory peptide somatostatin. These observations all focus on the fact that peptide T, somatostatin, and/or other peptides, might provide a clue to understanding the etiology and pathogenesis of psoriasis. Therefore, the effect of peptide T administration on somatostatin containing cutaneous cell populations was investigated. Ten psoriatic patients were treated with peptide T (D-Ala-peptide T amide; 2 mg/day i.v.) for 28 days. Serial biopsies were obtained from the psoriatic lesions before, once weekly during and 4 weeks after discontinuation of the peptide T treatment. An indirect immunofluorescence procedure was performed using a polyclonal antiserum against somatostatin. Clinically, most of the patients responded successfully to the treatment. Immunohistochemical investigations of the serial biopsies revealed the appearance of extensive changes in the number of dermal somatostatin immunoreactive dendritic cells. We believe that peptide T may stimulate the local synthesis and/or release of somatostatin, or proliferation and/or migration of certain dendritic cell populations in psoriatic lesions during healing. Since the benefits of peptide T treatment of psoriatic patients parallel earlier investigations using somatostatin infusions, it is likely that somatostatin given exogenously or synthesized/released endogenously plays a vital role in inducing the healing process.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7911613

    Sarcoidosis, a chronic granulomatous disease of unknown etiology, is treated with immune suppressive drugs such as corticosteroids. Sarcoidosis patients have been reported to benefit clinically from treatment with thalidomide. We administered thalidomide for 16 weeks to eight patients with chronic skin sarcoidosis and evaluated the drug's effects before and with treatment. After thalidomide treatment, all skin biopsies showed decreases in granuloma size and reduction in epidermal thickness. We also observed extensive T cell recruitment into the granulomas, the appearance of multinucleated giant cells, and increased numbers of dermal Langerhans cells (CD1a(+)) and mature dendritic cells (CD83(+) or DC-LAMP(+)). Plasma IL-12 levels increased and remained elevated during the treatment period. We noted increased HLA-DR expression on peripheral blood lymphocytes and a corresponding drop in the naive T cell marker CD45RA. Our data suggest that thalidomide treatment of sarcoidosis results in granuloma differentiation to a Th1-type cellular immune response usually associated with protective immunity to tuberculosis and tuberculoid leprosy.

    Aromatherapy has been suggested as an alternative therapeutic method for the treatment of atopic dermatitis (AD), eczema and other skin diseases. In the current study, the anti-atopic properties of the volatile organic compounds of Chamaecyparis obtusa (VOCCo) were examined to determine whether they are amenable for use as a pharmaceutical candidate. The alterations in histological features, serum IgE levels and mast cell infiltration following exposure to VOCCo were determined in a 2,4-dinitrochlorobenzene (DNCB)-induced AD-like mouse model. The results of these experiments demonstrated that VOCCo inhibited the development of AD-like skin lesions by reducing the serum IgE level and mast cell infiltration into the dermal and subcutaneous layers. This was supported by screening of immune cytokine mRNAs, including interleukin (IL)-1β and IL-6 from the skin of DNCB-treated mice. The expression of IL-1β and IL-6 in the skin lesions of mice was dose-dependently inhibited by treatment with VOCCo. Furthermore, treatment with VOCCo resulted in the recovery of histopathological features in AD-like skin lesions. These results suggest that VOCCo may have therapeutic and preventive effects for the development of AD. PMID:25760811

    Purpose: To determine the effect of low intensity laser therapy (LILT) on healing of infected skin wounds in the rat. Methods: Wounds on the dorsum of Sprague-Dawley rats (14 per group) were inoculated or sham-inoculated with P. aeruginosa. Wounds were irradiated or sham-irradiated three times weekly from Day 1-19 using 635nm or 808nm diode lasers at radiant exposure of 1 or 20 J/cm2 delivered in continuous wave (CW) or at an intensity modulation frequency of 3800Hz. Wound area and bacterial growth were evaluated three times weekly. Results: CW 808 nm (1 and 20 J/cm2) irradiation generally delayed healing in acute wounds. However, from Day 10 onwards CW 808 nm (1 J/cm2 and 20 J/cm2) and 808 nm 3800 Hz (1 J/cm2) irradiation improved healing in inoculated wounds. Healing in acute wounds improved using 635 nm irradiation at low radiant exposure (1 J/cm2); however, using 635 nm irradiation at high radiant exposure (20 J/cm2) delayed healing. Bacterial balance in wounds was significantly altered using 635 nm (20 J/cm2) and CW 808 nm irradiation (1 and 20 J/cm2). Conclusion: Clearing wounds of normal flora was not associated with improved healing. Proliferation of staphylococcal species in wounds was associated with delayed healing.

    Acute and long term effects are frequent after radiotherapy. They may alter the general status and quality of life of the patients. Chronic radiodermatitis may result in ulceration and in transformation into a squamous cell carcinoma. There is a correlation of the frequency of acute dermatitis with the total dose. Chronic radiodermatitis may develop after repeated small doses of ionizing radiation for cardiac catheterization and coronary angio-plasties. The other prognostic factors for the level of acute and late skin reactions are volume of tissue treated, total daily dose, fractionations schemes... but there are some variation in the degree of reaction in patients treated with identical radiotherapy schedules. There is a patient - to- patient variability. Several diseases as systemic sclerosis, some genetic diseases, perhaps some drugs may increase the cutaneous reactions. So both acute and chronic irradiation injury is a complex process with many regulations. Chronic fibrosis may be caused by mechanism of cell activation (and particularly fibroblasts). Cytokines e.g transforming growth factor {beta} (TGF-{beta}) might be involved in the induction of fibrosis. Treatment use emollients. Superoxide dismutase was used as an ointment for radio-fibrosis therapy and obtains a reduction of the fibrosis. In late phases plastic surgery or sometimes cryo-surgery can be used. (authors)

    Hartnup disease is an inborn abnormality of renal and intestinal transport involving the neutral amino acids. Intermittent pellagra-like rash, attacks of cerebellar ataxia and psychiatric disturbance are characteristic symptoms of this disease. We described here a patient with adult-onset Hartnup disease who presented unique neuropsychiatric symptoms but no dermatologic symptoms, and reported features of amino acids transport in this patient and his family. The patient, a man aged 37 years, was referred to us because of lasting daytime bruxism. He is the second child of healthy parents who are first cousin; his elder brother who has been mentally retarded became bed-ridden and died at 32 years of age. His younger brother is completely healthy. Although the patient's development in infancy has been slightly retarded, he completed compulsory 9-year education. At 29 years of age, he experienced episodes of diplopia, ataxic gait and insomnia, and at 33 years of age, of transient stupor. There had been no history of photosensitivity or dermatitis. On neurological examination, there were trunkal ataxia, increased muscular tone and decreased mental activity besides bruxism. These symptoms remained unchanged despite of several medications including trihexyphenidyl, diazepam, halloperidol, tiapride and sulpiride. Two months later, the patient became stuporous; bruxism and hypertonicity became exaggerated. Myerson's sign, sucking reflex and grasp reflex in both hand appeared. There was no dermal lesion. A cranial computed tomography revealed a small calcification in the right frontal subcortical region and a single photon emission tomography indicated possible bifrontal hypoperfusion. Electroencephalograms demonstrated non-specific slowing. Somatosensory evoked potentials and nerve conduction velocities were normal. There were constant indicanuria and amino-aciduria.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2582682

    Purpose: Flexible Freiburg flap used with high dose rate afterloaders is easy to cut into any size for any body site and to dwell with a precise source position, conforms to curved skin surface and then to the planned target. However, unlike intracavity or interstitial situations, incomplete scatter environment due to flap applicators exposed to air might lead to dose difference between the delivered and planned. This research is focused on the dose deviation of incomplete scatter versus full scatter. Methods: A 12x12 cm of Freiburg flap applicator was used for the validation. A Nucletron Oncentra Brachy Ver. 4.3 treatment planning system (TPS) was used for treatment planning. However, no heterogeneity correction incorporated into the brachytherap TPS needs to be considered. A Philips Brilliance CT Big Bore was employed for CT scan. Radiation was delivered using a Nucletron HDR remote afterloader system. A 10cm bolus was used to cover the flap for obtaining a full scatter. An OSL, ion chamber, and Gafchromic EBT2 film were used for commissioning the flap applicator. Results: The applicator calibration at 5mm depth was performed using an OSL dosimeter. Applicator source dwelling positions with 1D and 2D array exposed to and recorded by Gafchromic EBT2 film showed an agreement within 1mm. 1D array of Freiburg flap exhibited 4.2% cooler in dose with incomplete scatter than full scatter. 2D array showed 7.1% lower in dose for incomplete scatter than full scatter. The deviation was found more than 10% beyond 8cm in depth. Conclusion: Significant dose deviation caused by the incomplete scatter environment was found to be 7.1% at 1cm depth. This deviation was increased with increasing depth. The inaccuracy resulted from the incomplete scatter can be fixed by either placing a bolus on the top of the flap or making the plan at least 7% hotter.

    The first clinical trial of optical coherence tomography (OCT) combined with multiphoton tomography (MPT) and dermoscopy is reported. State-of-the-art (i) OCT systems for dermatology (e.g. multibeam swept source OCT), (ii) the femtosecond laser multiphoton tomograph DermaInspectTM, and (iii) digital dermoscopes were applied to 47 patients with a diversity of skin diseases and disorders such as skin cancer, psoriasis, hemangioma, connective tissue diseases, pigmented lesions, and autoimmune bullous skin diseases. Dermoscopy, also called 'epiluminescent microscopy', provides two-dimensional color images of the skin surface. OCT imaging is based on the detection of optical reflections within the tissue measured interferometrically whereas nonlinear excitation of endogenous fluorophores and the second harmonic generation are the bases of MPT images. OCT cross sectional "wide field" image provides a typical field of view of 5 x 2 mm2 and offers fast information on the depth and the volume of the investigated lesion. In comparison, multiphoton tomography presents 0.36 x 0.36 mm2 horizontal or diagonal sections of the region of interest within seconds with submicron resolution and down to a tissue depth of 200 μm. The combination of OCT and MPT provides a synergistic optical imaging modality for early detection of skin cancer and other skin diseases.

    Full Text Available B. burgdorferi sensu stricto, B. afzelii, B. garinii and B. bavariensis are the principal species which account for Lyme borreliosis (LB globally. We have developed an internally controlled duplex quantitative real time PCR assay targeting the Borrelia 16S rRNA and the human RNAseP genes. This assay is well-suited for laboratory confirmation of suspected cases of LB and will be used to assess the efficacy of a vaccine against LB in clinical trials. The assay is highly specific, successfully detecting DNA extracted from 83 diverse B. burgdorferi sensu lato strains representing all major species causing LB, while 21 unrelated microbial species and human genomic DNA tested negative. The assay was highly reproducible and sensitive, with a lower limit of detection of 6 copies per PCR reaction. Together with culture, the assay was used to evaluate paired 3 mm skin biopsy samples taken from 121 patients presenting with solitary erythema migrans (EM lesion. PCR testing identified more positive biopsy samples than culture (77.7% PCR positive versus 55.1% culture positive and correctly identified all specimens scored as culture positive. OspA-based typing identified the majority of isolates as B. afzelii (96.8% and the bacterial load was significantly higher in culture positive biopsies than in culture negative biopsies (P<0.001. The quantitative data also enabled relationships between Borrelia burden and patient symptoms to be evaluated. The bacterial load was significantly higher among patients with systemic symptoms than without (P = 0.02 and was significantly higher for biopsies retrieved from patients with EM lesions with central clearing (P<0.001. 16S copy numbers were moderately lower in samples from patients reporting a history of LB (P = 0.10. This is the first quantitative PCR study of human skin biopsies predominantly infected with B. afzelii and the first study to demonstrate a clear relationship between clinical symptoms in B. afzelii

    The objective of this study was to investigate the genetic relationships between skin lesion traits in group housed growing pigs as a measure of short- (in a newly mixed group) and long- (in a socially stable group) term aggression and commonly used commercial performance measures: growth, feed intake, feed efficiency, and carcass traits. Data on 2,413 growing pigs (138 groups) were available. Pigs were mixed into new social groups of 18 animals, and skin lesions were counted 24 h (SL24h) and 5 wk (SL5wk) postmixing. The animal model was used to estimate genetic parameters for skin lesion traits, test daily gain, lifetime daily gain, daily feed intake, feed efficiency (calculated as test daily gain divided by daily feed intake), loin depth, back fat, and HCW. Skin lesions had a heritable component, ranging from 0.08 for anterior SL24h to 0.22 for central SL5wk and would, therefore, be suitable as a method of phenotyping aggression for selection purposes. Significant positive genetic correlations were found between SL24h and SL5wk (0.46 to 0.81). Positive genetic correlations were also found between SL24h (central and posterior body regions) or SL5wk (all body regions) and the production traits lifetime daily gain, test daily gain, and HCW (0.29 to 0.54). Central SL24h, anterior SL5wk, and posterior SL5wk were found to correlate positively with feed efficiency (0.39 to 0.50), suggesting that pigs with more lesions convert feed more efficiently. Where significant, the magnitude of phenotypic correlations was low but positive (0.07 to 0.10). These results suggest that, genetically, animals that receive many lesions show improved performance compared to those with few lesions, except for anterior SL24h, which had previously been shown to be genetically positively correlated with the initiation of nonreciprocal attacks. It may, therefore, be possible, via selection against anterior skin lesions at mixing, to reduce this form of 1-sided aggression without adversely

    Full Text Available PURPOSE: To evaluate histological changes in the corneal stroma in pseudophakic bullous keratopathy. METHODS: Twenty-eight patients (28 eyes with pseudophakic bullous keratopathy underwent therapeutic penetrating keratoplasty at Shandong Eye Institute between January 2006 and November 2011. The patients were divided into two groups according to the duration of bullous keratopathy (1.0 year group, and three buttons from enucleated eyes with choroidal melanoma served as a control. In vivo confocal microscopy examination, hematoxylin-eosin, Masson's trichrome stain and Van Gieson staining were used for microscopic examination. The histological evaluation and scoring of the buttons for morphological changes, including the degree of stromal scars, neovascularization and inflammatory cells within the corneal buttons, were compared. To study the underlying mechanism, connective tissue growth factor (CTGF and TGF-β immunohistochemistry were performed. RESULTS: Confocal microscopy examination and histological evaluation and scoring of the buttons showed that compared with the 1.0 year group (P1.0 year group. CONCLUSIONS: During the progression of pseudophakic bullous keratopathy, stromal scars occurred more often in the patients that had a longer duration of disease. Cytokines such as CTGF and TGF-β1 may play a role in this pathological process and deserve further investigation.

    Bullous pemphigoid (BP) is an autoimmune blistering skin disease associated with autoantibodies against two hemidesmosomal proteins, BP180 (type XVII collagen) and BP230. As the pathogenic relevance of antibodies against the immunodominant NC16A domain of BP180 has been clearly demonstrated, specific removal of these antibodies should be a rational therapeutic approach. Here, we evaluated three recombinant forms of bacterially produced BP180 NC16A, a monomer, trimer, and tetramer, together with different matrices for their efficacy to specifically adsorb autoantibodies from BP plasma samples. An adsorber consisting of NC16A-trimer coupled to NHS-activated Sepharose 4 Fast Flow revealed satisfying adsorption rates and a high specificity. The NC16A-trimer adsorber was regenerable and autoclavable. It has the potential to be used for specific immunoadsorption to treat severe and refractory BP and other pemphigoid diseases associated with BP180 NC16A reactivity. PMID:26498290

    Full Text Available David Neal Franz Department of Pediatrics, Tuberous Sclerosis Clinic, Cincinnati Children's Hospital Medical Center, Cincinnati, OH, USA Abstract: Tuberous sclerosis complex (TSC is an autosomal dominant genetic disorder caused by inactivating mutations in either the TSC1 or TSC2 genes. It is characterized by the development of multiple, benign tumors in several organs throughout the body. Lesions occur in the brain, kidneys, heart, liver, lungs, and skin and result in seizures and epilepsy, mental retardation, autism, and renal and pulmonary organ system dysfunction, as well as other complications. Elucidation of the molecular pathways and etiological factors responsible for causing TSC has led to a paradigm shift in the management and treatment of the disease. TSC1 or TSC2 mutations lead to constitutive upregulation of the mammalian target of rapamycin pathway, which affects many cellular processes involved in tumor growth. By targeting mammalian target of rapamycin with everolimus, an orally active rapamycin derivative, clinically meaningful and statistically significant reductions in tumor burden have been achieved for the main brain (subependymal giant cell astrocytoma and renal manifestations (angiomyolipoma associated with TSC. This review provides an overview of TSC, everolimus, and the clinical trials that led to its approval for the treatment of TSC-associated subependymal giant cell astrocytoma and renal angiomyolipoma.

    Full Text Available OBJECTIVE: To analyze cytokine gene expression in keratinocytes from patients with systemic lupus erythematosus (SLE. INTRODUCTION: Keratinocytes represent 95% of epidermal cells and can secrete several cytokines. METHODS: Keratinocytes were obtained by laser microdissection from 21 patients with SLE (10 discoid and 11 acute lesions at involved and uninvolved sites. All patients were receiving a low/moderate prednisone dose and 18 were receiving chloroquine diphosphate. IL-2, IL-5, TNF-α and IFN-γ gene expression was evaluated by real-time PCR and expressed as the ratio (R to a pool of skin samples from 12 healthy volunteers. RESULTS: Heterogeneity in cytokine gene expression was found among patients with SLE. Eighteen of 38 valid SLE samples (47% presented overexpression (R>1 of at least one cytokine. Lesional skin samples tended to show higher cytokine expression than samples from uninvolved skin (p = 0.06. IL-5 and IFN-γ were the most commonly overexpressed cytokines. Samples with cytokine overexpression corresponded to more extensive and severe lesions. Prednisone dose did not differ between samples without cytokine overexpression (15.71±3.45 mg/day and those with overexpressed cytokines (12.68±5.41 mg/day (p = 0.216. Samples from all patients not receiving diphosphate chloroquine had at least one overexpressed cytokine. CONCLUSIONS: The heterogeneous keratinocyte cytokine gene expression reflects the complex immunological and inflammatory background in SLE. Patients with severe/extensive skin lesions showed a higher frequency of cytokine gene overexpression. Increased IFN-γ and IL-5 expression suggests that Th1 and Th2 cells are involved in SLE skin inflammation. The possibility that prednisone and antimalarial drugs may have contributed to low cytokine gene expression in some samples cannot be ruled out.

    There is increasing evidence that oxidative stress is an important risk factor for arsenic-related diseases. Peripheral blood leukocytes constitute an important defense against microorganisms or pathogens, while the research on the impact of chronic arsenic exposure on peripheral blood leukocytes is much more limited, especially at low level arsenic exposure. The purpose of the present study was to explore whether chronic arsenic exposure affects oxidative stress of peripheral blood leukocytes and possible linkages between oxidative stress and arsenic-induced skin lesions. 75 male inhabitants recruited from an As-endemic region of China were investigated in the present study. The classification of arsenicosis was based on the degree of skin lesions. Arsenic levels were measured in drinking water and urine by Atomic Fluorescence Spectroscopy. Urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG) was tested by Enzyme-Linked Immunosorbent Assay. 8-OHdG of peripheral blood leukocytes was evaluated using immunocytochemical staining. 8-OHdG-positive reactions were only present in polymorphonuclear leukocytes (PMNs), but not in monocytes (MNs). The 8-OHdG staining of PMN cytoplasm was observed in all investigated populations, while the 8-OHdG staining of PMN nuclei was frequently found along with the elevated amounts of cell debris in individuals with skin lesion. Urinary arsenic levels were increased in the severe skin lesion group compared with the normal group. No relationship was observed between drinking water arsenic or urine 8-OHdG and the degree of skin lesions. These findings indicated that the target and persistent oxidative stress in peripheral blood PMNs may be employed as a sensitive biomarker directly to assess adverse health effects caused by chronic exposure to lower levels of arsenic. -- Highlights: ► Male inhabitants were investigated from an As-endemic region of China. ► 8-OHdG-positive reactions were only present in polymorphonuclear leukocytes (PMNs).

In this study, we restrospectively analysed efficiency of Er: YAG laser therapy in the treatment of epidermal and dermal benign skin lesions. Materials and Methods: We retrospectively investigated our clinical records of 116 patients treated with Er: YAG laser between April 2011 and April 2013. The clinical records of 103 patients (47 men, 56 women were included in our study. Of these 103 patients included in the study were xanthelasma, solar lentigo, epidermal nevus, seborrheic keratosis, nevus of ota, syringoma, cafe au lait macules (CALM and other than these. Treatment parameters, demographic features and before and after photographs of the lesions were investigated from patients’ records in order to evaluate efficiency of Er: YAG laser therapy. Results: Of these 103 patients included in the study were evaluated in 8 groups, described as xanthelasma (n=21, syringoma (n=17, solar lentigo (n=16, epidermal nevus (n=11, seborrheic keratosis (n=9, nevus of ota (n=5, CALM (n=3 and other than these (n=21. In the Er: YAG laser treatment, the average energy flow was 3-7 J/cm2, the average pulse duration was 300 ms, the average number of passes was 3-5 repeat, and the average pulse frequency was 3-7 Hz. While 4.9% of the patients showed no improvement, 59.2% showed marked improvement, 26.2% showed moderate improvement and 9.7% showed mild improvement. Treatment responses in xanthelasma, syringoma, epidermal nevus, solar lentigo and CALM lesions were statistically significant. Observed side effects were hyperpigmentation in 4 patients, hypopigmentation in 3 patients, hypertrophic scar in 2 patients and persistent erythema in one patient and the treatment was well tolerated by all the patients. Conclusion: Er: YAG laser is an effective and safe treatment option in the treatment of benign skin lesions especially in epidermal lesions.

    It has been demonstrated that dermoscopic monitoring of melanocytic lesions allows for the recognition of melanoma in early stages while minimizing the excision of benign lesions. However, it is still pending to determine the real impact of digital follow-up in the clinical management of pigmented lesions. To assess the evidence of follow-up of melanocytic skin lesions with digital dermoscopy in the management of individuals at risk for melanoma by performing a meta-analysis. Medline database was screened, no limits in terms of date or language were applied. Original studies were selected when the following criteria were met: performed in clinical setting with clinical and dermoscopic evaluation made by physicians, data regarding population characteristics included, follow-up strategy used described. Fourteen of 145 retrieved references were retained. Included studies account for a total of 5787 patients (mean 445 per study) and 52,739 lesions monitored (mean per study 4057; range 272-11,396) with a mean of 12 lesions monitored per patient; a total of 4388 lesions (8.3%) were excised. The mean length of follow-up was 30 months. A mean of digital dermoscopy follow-up, the proportion of in situ melanoma and thin melanomas are higher than expected in general population. Chances to detect a melanoma during surveillance increase as the length of follow-up extends.

    In the last few years, Raman spectroscopy has been increasingly used for the characterization of normal and pathological tissues. A new Raman system, constituted of optic fibers bundle coupled to an axial Raman spectrometer (Horiba Jobin Yvon SAS), was developed for in vivo investigations. Here, we present in vivo analysis on two tissues: human skin and esophagus mucosa on a rat model. The skin is a directly accessible organ, representing a high diversity of lesions and cancers. Including malignant melanoma, basal cell carcinoma and the squamous cell carcinoma, skin cancer is the cancer with the highest incidence worldwide. Several Raman investigations were performed to discriminate and classify different types of skin lesions, on thin sections of biopsies. Here, we try to characterize in vivo the different types of skin cancers in order to be able to detect them in their early stages of development and to define precisely the exeresis limits. Barrett's mucosa was also studied by in vivo examination of rat's esophagus. Barrett's mucosa, induced by gastro-esophageal reflux, is a pretumoral state that has to be carefully monitored due to its high risk of evolution in adenocarcinoma. A better knowledge of the histological transformation of esophagus epithelium in a Barrett's type will lead to a more efficient detection of the pathology for its early diagnosis. To study these changes, an animal model (rats developing Barrett's mucosa after duodenum - esophagus anastomosis) was used. Potential of vibrational spectroscopy for Barrett's mucosa identification is assessed on this model.

    Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects a large percent of the world́s population. This long-lasting skin disease has been treated by different approaches according to its causative agent and severity. Nonetheless, the use of advanced biomaterials to treat AD is poorly explored. The present study assessed the protective effectiveness of biocomposites films based on chitosan (Cs), poly(vinyl alcohol) (PVA) and bovine bone powder (BBP) on AD-like skin lesions. These original biocomposites were fully characterized and in vivo biological assays concerning the AD treatment were performed using a mouse model induced by 2,4-dinitrochlorobenzene (DNCB). The dorsal skin and ear of Balb/c female mice were challenging cutaneously with DNCB. Our findings demonstrate BBP-based biocomposite attenuated and treated considerably the DNCB-induced skin lesions in an AD-like model. In this sense, this study suggests that this original biocomposite may be applied as an active biomaterial for AD treatment. PMID:27185122

    Summary: This study investigated the contents and distribution of collagen Ⅴ (Col Ⅴ) in skin lesions of the patients with systemic sclerosis (SSc) and its roles in the pathogenesis. The contents and distribution for al chain of collagen type Ⅰ,Ⅲ and [α1 (Ⅰ), α1 (Ⅲ) and α1 (Ⅴ)] in skin lesions of 36 patients with SSc (9 cases of mild fibrosis, 14 moderate, and 13 severe) were detected by using immunohistochemical SP method. Six cases of normal skin tissues served as controls. The results showed that there was diffuse distribution for three kinds of collagens in dennis. The deep staining α1 (Ⅰ) and α1 (Ⅲ) masses or bands were seen in reticular layer, while α1 (Ⅴ) was distributed more homogeneously. From control to weak, moderate and severe fibrosis stages, α1(Ⅰ), α1 (Ⅲ) and α1 (Ⅴ) showed a gradually increased trend in skin lesions (P<0.05). α1(Ⅴ) was obviously elevated in skin lesions at early stage and persisted in whole fibrotic process and risen in greater contents, while α1 (1) and α1(Ⅲ) were to go higher late and were apparently elevated at moderate and late stages. Compared with α1(Ⅰ), α1(Ⅴ) took leading increase at early stage in skin lesions (P<0.01), and had more elevated contents than α1 (Ⅲ) at moderate and late stages. The fibrotic changes in dermal reticular layer occurred earlier than those in papillary layer, and the abnormalities of α1 (Ⅴ)/ α1(Ⅰ) ratio appeared before α1 (Ⅲ)/α1 (Ⅰ) ratio. It was concluded that a lot of α1(Ⅴ) began to deposit in greater contents prior to α1 (Ⅰ) and α1(Ⅲ) at early stage in SSc and persisted in whole fibrotic process. The changes of α1(Ⅴ) contents in reticular layer occurred earlier than those in papillary layer, and it suggested that the fibrosis in reticular layer appeared earlier.

    Full Text Available Abstract Background Mineral water from deep-sea bedrock, formed over thousands of years, is rich in minerals such as Ca, Mg, Na, K, Fe and others. Our present study was to investigate the preventive effects of natural deep-sea water on developing atopic dermatitis (AD. Methods We elicited AD by application of DNCB (2,4-dinitro-chlorobezene in Nc/Nga mouse dorsal skin. Deep Sea water (DSW was filtered and concentrated by a nanofiltration process and reverse osmosis. We applied concentrated DSW (CDSW to lesions five times per week for six weeks, followed by evaluation. 1% pimecrolimus ointment was used as positive control. The severity of skin lesions was assessed macroscopically and histologically. Levels of inflammatory mediators and cytokines in the serum were detected by Enzyme-linked immunosorbent assay (ELISA and the levels of CD4+ and CD8+ spleen lymphocytes were determined by flow cytometry analysis. Results DNCB-treated mice showed atopic dermatitis-like skin lesions. Treatment of mice with CDSW reduced the severity of symptoms in the skin lesions, including edema, erythema, dryness, itching, and transepidermal water loss (TEWL. Histological analyses demonstrated that epidermal thickness and infiltration of inflammatory cells were decreased after CDSW treatment. Given these interesting observations, we further evaluated the effect of CDSW on immune responses in this AD model. Treatment AD mice with CDSW inhibited up-regulation of IgE, histamine, and pro-inflammatory cytokines in the serum. Also, the CD4+/CD8+ ratio in spleen lymphocyte was down-regulated after treatment with CDSW. Finally, cytokines, especially IL-4 and IL-10 which are important for Th2 cell development, were reduced. Conclusions Our data suggests that topical application of CDSW could be useful in preventing the development of atopic dermatitis.

    Due to life history and physiological constraints, cetaceans (whales) are unable to avoid prolonged exposure to external environmental insults, such as solar ultraviolet radiation (UV). The majority of studies on the effects of UV on skin are restricted to humans and laboratory animals, but it is important to develop tools to understand the effects of UV damage on large mammals such as whales, as these animals are long-lived and widely distributed, and can reflect the effects of UV across a large geographical range. We and others have used mitochondrial DNA (mtDNA) as a reliable marker of UV-induced damage particularly in human skin. UV-induced mtDNA strand breaks or lesions accumulate throughout the lifespan of an individual, thus constituting an excellent biomarker for cumulative exposure. Based on our previous studies in human skin, we have developed for the first time in the literature a quantitative real-time PCR methodology to detect and quantify mtDNA lesions in skin from sun-blistered whales. Furthermore the methodology allows for simultaneous detection of mtDNA damage in different species. Therefore using 44 epidermal mtDNA samples collected from 15 blue whales, 10 fin whales, and 19 sperm whales from the Gulf of California, Mexico, we quantified damage across 4.3 kilobases, a large region of the ~16,400 base pair whale mitochondrial genome. The results show a range of mtDNA damage in the skin of the three different whale species. This previously unreported observation was correlated with apoptotic damage and microscopic lesions, both of which are markers of UV-induced damage. As is the case in human studies, this suggests the potential use of mtDNA as a biomarker for measuring the effect of cumulative UV exposure in whales and may provide a platform to help understand the effects of changing global environmental conditions.

    The use of a broad spectrum of novel detection systems for autoantibodies to the basement membrane proteins BP180 and BP230 has greatly facilitated the diagnosis of bullous pemphigoid, which most likely explains its increasing incidence in central Europe. Because the pathogenic relevance of antibodies to human BP180 has been convincingly shown both in vitro and in vivo, repeated testing for these antibodies appears to be helpful in guiding treatment decisions during the course of the disease.

    Fab fragments (Fabs), which lack effector functions due to the absence of the Fc portion, maintain the ability to bind to specific allergens. In the present study, we examined whether Fabs of an allergen-specific IgG1 monoclonal antibody (mAb) were able to regulate allergen-induced atopic dermatitis-like skin lesions in mice. BALB/c mice passively sensitized with ovalbumin (OVA)-specific IgE mAb were repeatedly challenged with OVA applied to the skin after sodium dodecyl sulfate treatment. Fabs prepared by the digestion of anti-OVA IgG1 mAb (O1-10) with papain were applied to the skin 30min before the OVA challenges followed by measurement of clinical symptoms including erythema/hemorrhage, edema, scarring/dryness, and excoriation/erosion of the skin. Treatment with O1-10 Fabs, but not intact O1-10, showed inhibition of clinical symptoms (P<0.01) induced by the repeated OVA challenges in the sensitized mice; O1-10 Fabs suppressed histological changes such as epidermal hyperplasia (P<0.01) and the accumulation of mast cells (P<0.01) and neutrophils (P<0.01). Furthermore, treatment with O1-10 Fabs inhibited the increase in levels of IL-13 (P<0.01) and IL-17A production (P<0.05) in the lymph nodes of the sensitized mice. Additionally, the increased level of OVA in serum following the repeated OVA challenges in the sensitized mice was reduced by the treatment (P<0.05). These results suggest that topical application of pathogenic allergen-specific IgG1 mAb Fabs to the skin of mice is effective in suppressing allergen-induced atopic dermatitis-like skin lesions, suggesting that allergen-specific mAb Fabs could be used as a tool to regulate allergen-induced atopic dermatitis.

    Full Text Available Background: Congenital epidermolysis bullosa (CEB is a rare genodermatosis. The digestive system is very frequently associated with skin manifestations. Pyloric atresia (PA and oesophageal stenosis (OS are considered the most serious digestive lesions to occur.The aim of this work is to study the management and the outcome of digestive lesions associated to CEB in four children and to compare our results to the literature. Patients and Methods: A retrospective study of four observations: Two cases of PA and two cases of OS associated to CEB managed in the Paediatric Surgery Department of Fattouma Bourguiba Teaching Hospital in Monastir, Tunisia. Results: Four patients, two of them are 11 and 8 years old, diagnosed as having a dystrophic epidermolysis bullosa since the neonatal period. They were admitted for the investigation of progressive dysphagia. Oesophageal stenosis was confirmed by an upper contrast study. Pneumatic dilation was the advocated therapeutic method for both patients with afavourable outcome. The two other patients are newborns, diagnosed to have a CEB because of association of PA with bullous skin lesions with erosive scars. Both patients had a complete diaphragm excision with pyloroplasty. They died at the age of 4 and 3 months of severe diarrhoea resistant to medical treatment. Conclusion: Digestive lesions associated to CEB represent an aggravating factor of a serious disease. OS complicating CEB is severe with difficult management. Pneumatic dilatation is the gold standard treatment method. However, the mortality rate in PA with CEB is high. Prenatal diagnosis of PA is possible, and it can help avoiding lethal forms.

    Human skin provides a barrier between the host and the physical, chemical, and biological environment. It is also a potential portal of entry for hazardous or infectious agents and a potential target of environmental toxins. Cutaneous vulnerability may take on many forms in the embryo, infant, child, and adolescent. Teratogenic agents may occasionally target skin, as appreciated in the proposed association of the antithyroid medication methimazole, with the congenital malformation known as aplasia cutis congenita. Percutaneous absorption of topically applied substances and the potential for resultant drug toxicities are important considerations in the child. Many topical agents have been associated with systemic toxicity, including alcohol, hexachlorophene, iodine-containing compounds, eutectic mixture of local anesthetics, and lindane. Percutaneous toxicity is of greatest concern in the premature infant, in whom immaturity of the epidermal permeability barrier results in disproportionately increased absorption. Immature drug metabolism capabilities may further contribute to the increased risk in this population. Ultraviolet (UV) radiation exposure, which increases an individual's risk of cutaneous carcinogenesis, may be a particularly significant risk factor when it occurs during childhood. The "critical period hypothesis" suggests that UV exposure early in life increases the risk of eventual development of malignant melanoma. Other risk factors for malignant melanoma may include severe sunburns during childhood, intense intermittent UV exposure, and increased susceptibility of pediatric melanocytes to UV-induced DNA damage. Last, percutaneous exposure to environmental toxins and chemicals, such as insecticides and polychlorinated biphenyls, may differ between children and adults for several reasons, including behavioral patterns, anatomic and physiologic variations, and developmental differences of vital organs.

    Full Text Available Pemfigus is an autoimmune bullous skin disease, characterized by intraepidermal blisters. It is a severe and potentially life-threatening chronic disease with blisters and erosions on the mucosae and the skin. Treatment options do not differ for two most common types of pemphigus, pemphigus vulgaris and pemphigus foliaceus, except that the latter is usually less resistant to treatment and corticosteroids can often be started at lower doses. Systemic corticosteroids are still the most widely used drugs in the treatment of pemphigus and continue to be the mainstay of therapy for this disease. Adjuvant drugs are commonly used in combination with the aims of increasing efficacy and of having a steroid-sparing action, thereby allowing reduced corticosteroid side-effects. Mortality and complete remission rates have improved since the introduction of adjuvant drugs to pemphigus. Adjuvant drugs include immunoadsorbtion, corticosteroid pulse therapy, intravenous immunoglobulin (IVIG, immunosuppressive agents such as azathioprine, cyclophosphamide, mycophenolate mofetil and and anti-CD20 monoclonal antibody (rituximab. The lack of consensus in the published literature about the treatment of this disorder is responsible for different treatment strategies. Treatments need to be chosen after careful consideration of the potential benefits and side effects according to the patients’ medical condition. Here, both conventional therapies and novel treatment regimens for pemphigus are discussed. (Turkderm 2011; 45 Suppl 1: 44-53

    Staphylococcus aureus is highly prevalent among patients with atopic dermatitis (AD), and this pathogen may trigger and aggravate AD lesions. The aim of this study was to determine the prevalence of S. aureus in the nares of pediatric subjects and verify the phenotypic and molecular characteristics of the isolates in pediatric patients with AD. Isolates were tested for antimicrobial susceptibility, SCCmectyping, and Panton-Valentine Leukocidin (PVL) genes. Lineages were determined by pulsed-field gel electrophoresis and multilocus sequence typing (MLST). AD severity was assessed with the Scoring Atopic Dermatitis (SCORAD) index. Among 106 patients, 90 (85%) presented S. aureus isolates in their nares, and 8 also presented the pathogen in their skin infections. Two patients had two positive lesions, making a total of 10 S. aureusisolates from skin infections. Methicillin-resistant S. aureus(MRSA) was detected in 24 (26.6%) patients, and PVL genes were identified in 21 (23.3%), including 6 (75%) of the 8 patients with skin lesions but mainly in patients with severe and moderate SCORAD values (P=0.0095). All 24 MRSA isolates were susceptible to trimethoprim/sulfamethoxazole, while 8 isolates had a minimum inhibitory concentration (MIC) to mupirocin >1024 μg/mL. High lineage diversity was found among the isolates including USA1100/ST30, USA400/ST1, USA800/ST5, ST83, ST188, ST718, ST1635, and ST2791. There was a high prevalence of MRSA and PVL genes among the isolates recovered in this study. PVL genes were found mostly among patients with severe and moderate SCORAD values. These findings can help clinicians improve the therapies and strategies for the management of pediatric patients with AD.

    Acute and late radiation-induced injury on skin and subcutaneous tissues are associated with substantial morbidity in radiation therapy, interventional procedures and also are of concern in the context of nuclear or radiological accidents. Pathogenesis is initiated by depletion of acutely responding epithelial tissues and damage to vascular endothelial microvessels. Efforts for medical management of severe radiation-induced lesions have been made. Nevertheless, the development of strategies to promote wound healing, including stem cell therapy, is required. From 1997 to 2014, over 248 patients were referred to the Radiopathology Committee of Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires (Burns Hospital) for the diagnosis and therapy of radiation-induced localized lesions. As part of the strategies for the management of severe cases, there is an ongoing research and development protocol on 'Translational Clinical Trial phases I/II to evaluate the safety and efficacy of adult mesenchymal stem cells from bone marrow for the treatment of large burns and radiological lesions'. The object of this work was to describe the actions carried out by the Radiopathology Committee of the Burns Hospital in a chronic case with more than 30 years of evolution without positive response to conventional treatments. The approach involved the evaluation of the tissular compromise of the lesion, the prognosis and the personalized treatment, including regenerative therapy.

  17. Overrepresentation of IL-17A and IL-22 producing CD8 T cells in lesional skin suggests their involvement in the pathogenesis of psoriasis.

    Directory of Open Access Journals (Sweden)

    Pieter C M Res

    Full Text Available BACKGROUND: Although recent studies indicate a crucial role for IL-17A and IL-22 producing T cells in the pathogenesis of psoriasis, limited information is available on their frequency and heterogeneity and their distribution in skin in situ. METHODOLOGY/PRINCIPAL FINDINGS: By spectral imaging analysis of double-stained skin sections we demonstrated that IL-17 was mainly expressed by mast cells and neutrophils and IL-22 by macrophages and dendritic cells. Only an occasional IL-17(pos, but no IL-22(pos T cell could be detected in psoriatic skin, whereas neither of these cytokines was expressed by T cells in normal skin. However, examination of in vitro-activated T cells by flow cytometry revealed that substantial percentages of skin-derived CD4 and CD8 T cells were able to produce IL-17A alone or together with IL-22 (i.e. Th17 and Tc17, respectively or to produce IL-22 in absence of IL-17A and IFN-γ (i.e. Th22 and Tc22, respectively. Remarkably, a significant proportional rise in Tc17 and Tc22 cells, but not in Th17 and Th22 cells, was found in T cells isolated from psoriatic versus normal skin. Interestingly, we found IL-22 single-producers in many skin-derived IL-17A(pos CD4 and CD8 T cell clones, suggesting that in vivo IL-22 single-producers may arise from IL-17A(pos T cells as well. CONCLUSIONS/SIGNIFICANCE: The increased presence of Tc17 and Tc22 cells in lesional psoriatic skin suggests that these types of CD8 T cells play a significant role in the pathogenesis of psoriasis. As part of the skin-derived IL-17A(pos CD4 and CD8 T clones developed into IL-22 single-producers, this demonstrates plasticity in their cytokine production profile and suggests a developmental relationship between Th17 and Th22 cells and between Tc17 and Tc22 cells.

    Skin and joint manifestations are part of the clinical spectrum of many disorders. Well-known associations include psoriatic arthritis and arthritis associated with autoimmune connective tissue diseases. This review focuses on less common associations where skin lesions can provide easily accessible and valuable diagnostic clues, and directly lead to the specific diagnosis or limit the list of possibilities. This may also affect health care resources as diagnostic tests are often low-specific, highly expensive and poorly available. This group of diseases can be divided into two subsets, based on the presence/absence of fever, and then further classified according to elementary skin lesions (macular, urticarial, maculo-papular, vesico-bullous, pustular, petechial and nodular). In most instances joint involvement occurs as peripheral migrating polyarthritis. Erythematosus macular or urticarial rashes occur in most febrile disorders such as monogenic autoinflammatory syndromes, Schnitzler's syndrome, Still's disease and rheumatic fever and afebrile diseases as urticarial vasculitis. Pustular rash may be observed in chronic recurrent multifocal osteomyelitis (CRMO) and pyogenic arthritis with pyoderma gangrenosum and acne (PAPA) syndrome (both febrile) as well as in Behcet's disease and Synovitis, acne, pustulosis, hyperostosis and osteitis syndrome (both non-febrile). Papular lesions are typical of secondary syphilis, sarcoidosis, interstitial granulomatous dermatitis, papular petechial of cutaneous small-vessel vasculitis and nodular lesions of polyarteritis nodosa and multicentric reticulohistiocytosis all of which are afebrile. Differential diagnosis includes infections and drug reactions which may mimic several of these conditions. To biopsy the right skin lesion at the right time it is essential to obtain relevant histological information. PMID:23980929

    Telomerase activity is usually detected in most tumor tissues but not in normal tissues. Recently, there is increasing evidence that telomerase activity is associated with cell proliferation without malignancy, whereas there is little information about telomerase activity and its relationship with cell proliferation in chronic hyperproliferative skin diseases. Thus, we studied telomerase activity in skins from 10 patients with psoriasis and compared telomerase activity with the expression of ...

    The first-ever application of high-frequency ultrasound combined with multiphoton tomography (MPT) and dermoscopy in a clinical trial is reported. 47 patients with different dermatoses such as benign and malign skin cancers, connective tissue diseases, inflammatory skin diseases, and autoimmune bullous skin diseases have been investigated with (i) state-of-the-art and highly sophisticated ultrasound systems for dermatology, (ii) the femtosecond laser multiphoton tomograph and (iii) dermoscopes. Dermoscopy provides two-dimensional color images of the skin surface with a magnification up to 70 x. Depending on the ultrasonic frequencies from 7.5 MHz to 100 MHz, the signal depth varies from about 1 mm to 80 mm. Vertical ultrasound wide-field images provide fast information on depth and volume of the lesion. The 100 MHz ultrasound allows imaging with resolutions down to 16 μm (axial) and 32 μm (lateral). Multiphoton tomography provides 0.36 x 0.36 x 0.001 mm³ horizontal optical sections of a particular region of interest with submicron resolution down to 200 μm tissue depth. The autofluorescence of mitochondrial coenzymes, keratin, melanin, and elastin as well as the network of collagen structures can be imaged. The combination of ultrasound and MPT opens novel synergistic possibilities in diagnostics of skin diseases with a special focus on the early detection of skin cancer as well as the evaluation of treatments.

    Introduction Mechanisms responsible for UVA1 efficacy in atopic dermatitis (AD) are not fully elucidated. Aim To investigate IL-8, CCR-4, and IFN-γ mRNA expression in AD before and after UVA1, to identify correlations among them, and to determine whether and to what degree mRNA expression is influenced by UVA1. Material and methods Twenty-five patients with AD underwent medium dose UVA1-phototherapy at daily dosages of 10, 20, 30, 45, and then continuing 45 J/cm2 up to 20 days, from Monday to Friday for 4 weeks. Before and after UVA1, biopsies from acute skin lesions were studied using reverse-transcription and RT-PCR. Results The levels of CCR-4 mRNA correlated with those of IFN-γ, both before and after UVA1 phototherapy (p parallel with IFN-γ in acute skin lesions of patients with AD both before and after UVA1 phototherapy. UVA1 significantly improves SCORAD index, lessens the severity of AD and increases the expression of IL-8, with no direct effects on other studied molecules. PMID:27512350

    We report 3 year old male, referred for evaluation of developmental delays. Pregnancy was complicated by oligohydramnios, proteinuria and prematurity. Medical history revealed: bilateral inguinal hernia, small scrotal sac, undescended testes, developmental delays and behavioral problems. The child had: microcephaly, facial dysmorphic features, single palmar creases, hypopigmented skin lesions of variable size, intermittent exotropia and small retracted testes. Neurological examination was normal. Cognitive level was at the average range with mild delay in his adaptive behavior. Expressive language delays and severe articulation disorder were noted, as well as clumsiness, poor control and precision of gross and fine motor skills. Chromosomal analysis of peripheral leukocytes indicated that one of the number 11 chromosomes had undergone a pericentric inversion with breakpoints on the short (p) arm at band p14.3 and the long (q) arm at band q21. An MRI of the brain showed mild delay in myelinization pattern of white matter. Chromosome 11 inversion in other sites was associated with Beckwith-Wiedemann syndrome and several malignancies. To our knowledge this is the first description of inv(11)(p14.3q21) that is associated with microcephaly, dysmorphic features, hypopigmented skin lesions and speech delay. This inversion may disrupt the expression of the involved genes. However, additional cases with the same cytogenetic anomaly are needed to explore the phenotypic significance of this disorder.

    Full Text Available Despite recent advances in understanding the pathological pathways, clinical pattern and management opportunities for new-onset psoriasis as a paradoxical adverse event in patients receiving TNF inhibitors for their immune-mediated disorder, there is a subset of patients who are either partial responders or non-responders, whatever the therapeutic scenario. We present the case of new-onset psoriasis and severe alopecia development in a case study of long-standing rheumatoid arthritis (RA treated with adalimumab (ADA and leflunomide. Since skin lesions and alopecia are resistant to the classic protocol (topical treatment, ADA discontinuation and RA becomes highly active, rituximab (RTX was started. Dramatic improvement in joint disease, total remission of alopecia and partial remission of pustular psoriasis were described after the first RTX cycle. Although B-cell-depleting agents result in controversial effects on psoriatic skin lesions, this is the first case of ADA-induced psoriasis and alopecia that improved under RTX, suggesting a possible role in treating such a patient population.

    ABSTRACT Objective: identify nursing diagnoses in patients with immune-bullous dermatosis. Method: a quantitative and descriptive research, carried out in three institutions located in Rio de Janeiro and Mato Grosso do Sul, Brazil, using the Client Assessment Protocol in Dermatology during a nursing consultation. Simple descriptive statistics was used for data analysis. Results: 14 subjects participated in the study, nine with a diagnosis of pemphigus vulgaris, pemphigus two and three of bullous pemphigoid. The age ranged between 27 and 82 years, predominantly females (11). 14 nursing diagnoses were discussed and identified from a clinical rationale in all study participants, representing the most common human responses in this sample. The application of the Assessment Protocol in Dermatology facilitated the comprehensive assessment, in addition to providing the identification of diagnostics according to the North American Nursing Diagnosis Association International. Conclusion: the nursing diagnoses presented confirm the necessity of interdisciplinary work during the care for this clientele. For better description of the phenomena related to the client in question, it is suggested the inclusion of two risk factors related in three diagnoses of this taxonomy. It is worth noting the contribution of the findings for the care, education and research in nursing in dermatology. PMID:27533274

    Definitive diagnosis of the bat disease white-nose syndrome (WNS) requires histologic analysis to identify the cutaneous erosions caused by the fungal pathogen Pseudogymnoascus [formerly Geomyces] destructans (Pd). Gross visual inspection does not distinguish bats with or without WNS, and no nonlethal, on-site, preliminary screening methods are available for WNS in bats. We demonstrate that long-wave ultraviolet (UV) light (wavelength 368–385 nm) elicits a distinct orange–yellow fluorescence in bat-wing membranes (skin) that corresponds directly with the fungal cupping erosions in histologic sections of skin that are the current gold standard for diagnosis of WNS. Between March 2009 and April 2012, wing membranes from 168 North American bat carcasses submitted to the U.S. Geological Survey National Wildlife Health Center were examined with the use of both UV light and histology. Comparison of these techniques showed that 98.8% of the bats with foci of orange–yellow wing fluorescence (n = 80) were WNS-positive based on histologic diagnosis; bat wings that did not fluoresce under UV light (n = 88) were all histologically negative for WNS lesions. Punch biopsy samples as small as 3 mm taken from areas of wing with UV fluorescence were effective for identifying lesions diagnostic for WNS by histopathology. In a nonlethal biopsy-based study of 62 bats sampled (4-mm diameter) in hibernacula of the Czech Republic during 2012, 95.5% of fluorescent (n = 22) and 100% of nonfluorescent (n = 40) wing samples were confirmed by histopathology to be WNS positive and negative, respectively. This evidence supports use of long-wave UV light as a nonlethal and field-applicable method to screen bats for lesions indicative of WNS. Further, UV fluorescence can be used to guide targeted, nonlethal biopsy sampling for follow-up molecular testing, fungal culture analysis, and histologic confirmation of WNS.

    IL-17A is pivotal in the etiology of psoriasis, and CD8(+) T cells with the ability to produce this cytokine (Tc17 cells) are over-represented in psoriatic lesions. Here we demonstrate that the frequency of Tc17 cells in peripheral blood of psoriasis patients correlated with the clinical severity of the disease. Analysis of cutaneous-associated lymphocyte antigen expression showed that the blood Tc17 population contains a significantly higher proportion of cells with skin-homing potential compared with the CD8(+) T-cell population lacking IL-17A/IL-22 expression. IL-17A-producing CD8(+) T cells in blood have previously been reported to belong mainly to the mucosa-associated invariant T-cell (MAIT cell) lineage characterized by TCR Vα7.2 chain, CD161, IL-18Rα, and multidrug transporter ABCB1 expression. We demonstrate the presence of CD8(+) MAIT cells in the dermis and epidermis of psoriatic plaques, as well as healthy skin; however, IL-17A-producing CD8(+) MAIT cells were predominantly found in psoriatic skin. Notably, we observed IL-17A production in a large proportion of psoriatic plaque-derived CD8(+) T cells devoid of MAIT cell characteristics, likely representing conventional CD8(+) T cells. In conclusion, we provide supporting evidence that implicates Tc17 cells in the pathogenesis of psoriasis and describe the presence of innate CD8(+) MAIT cells in psoriatic lesions as an alternative source of IL-17A.

    We investigated the physicochemical properties of pH-sensitive hydroxyethyl cellulose (HEC)/hyaluronic acid (HA) complex hydrogels containing isoliquiritigenin (ILTG), and discussed potential applications as transdermal delivery systems for the treatment of skin lesions caused by pH imbalance. HA has skin compatibility and pH functional groups and HEC serves as scaffold to build hydrogels with varied HCE:HA mass ratio. Hydrogels were synthesized via chemical cross-linking, and three-dimensional network structures were characterized via scanning electron microscopy (SEM). The swelling properties and polymer ratios of the hydrogels were investigated at pH values in the range 1-13. HECHA13 (i.e., an HEC:HA mass ratio of 1:3) was found to have optimal rheological and adhesive properties, and was used to investigate the drug release efficiency as a function of pH; the efficiency was greater than 70% at pH 7. Antimicrobial activity assays against Propionibacterium acnes were conducted to take advantage of the pH-sensitive properties of HECHA13. At pH 7, we found that HECHA13, which contained ILTG, inhibited the growth of P. acnes. Furthermore, HECHA13 was found to exhibit excellent permeability into the skin, which penetrated mostly via the hair follicle. These results indicate that this pH-sensitive hydrogel is effective as a transdermal delivery system for antimicrobial therapeutics, with potential applications in the treatment of acne.

    Bullous pemphigoid (BP) is an autoimmune blistering dermatosis of the elderly mediated by IgG and IgE antibodies to skin hemidesmosomal proteins, BP180 and/or BP230, that occur physiologically also in neuronal tissue. It was reported that BP is associated with neurodegenerative diseases (ND). We performed a retrospective study in a setting of a Central European university dermatology department on prevalence of ND in 94 BP patients. 26 out of 94 BP patients had at least one ND. ND included: Parkinson's disease, dementia, stroke, hear loss, tinnitus, blindness, vertigo, neurosyphilis, systemic sclerosis, and epilepsy. Since population aging is conceivably responsible for the rising number of BP cases as a result of immunosenescence-related phenomena, the plausible BP-specific immunopathogenetic relationship between BP and ND deserves to be further experimentally explored.

    Full Text Available Abstract Background Sulfur mustard (SM is a blister-forming agent that has been used as a chemical weapon. Sulfur mustard can cause damage in various organs, especially the skin, respiratory system, and eyes. Generally, the multiple complications of mustard gas result from its alkalizing potency; it reacts with cellular components like DNA, RNA, proteins, and lipid membranes. TGF-β is a multi-functional cytokine with multiple biological effects ranging from cell differentiation and growth inhibition to extracellular matrix stimulation, immunosuppression, and immunomodulation. TGF-β has 3 isoforms (TGF-β 1, 2, 3 and its signaling is mediated by its receptors: R1, R2 and intracellular Smads molecules. TGF-β has been shown to have anti-inflammatory effects. TGF-βs and their receptors also have an important role in modulation of skin inflammation, proliferation of epidermal cells, and wound healing, and they have been implicated in different types of skin inflammatory disorders. Methods Seventeen exposed SM individuals (48.47 ± 9.3 years, 17 chronic dermatitis patients (46.52 ± 14.6 years, and 5 normal controls (44.00 ± 14.6 years were enrolled in this study. Evaluation of TGF-βs and their receptors expressions was performed by semiquantitative RT-PCR. Only TGF1was analyzed immunohistochemically. Results Our results showed significant decreases in the expression percentages of TGF-β 1, 2 and R1, R2 in chemical victims in comparison with chronic dermatitis and normal subjects and significant decreases in the intensity of R1 and R2 expressions in chemical victims in comparison with chronic dermatitis and normal controls. (P value Conclusions TGF-βs and their receptors appear to have a noticeable role in chronic inflammatory skin lesions caused by sulfur mustard.

The current study explores the immunomodulatory and histological effects of nanoparticle (NP-based transcutaneous delivery of hydrocortisone (HC. Methods: In this study, HC, the least potent topical glucocorticoid, was administered transcutaneously as chitosan NPs. The pharmacological and immunological effects of the NP-based HC delivery on the alleviation of 2,4-dinitrofluorobenzene-induced atopic dermatitis (AD-like skin lesions were evaluated using the NC/Nga mouse model. Results: In vivo Dino-Lite® microscopic assessment revealed that the NP-based formulation displayed a remarkable ability to reduce the severity of the pathological features of AD (dermatitis index, 3.0. The AD suppressive activity of the NP-based topical formulation was expected owing to the interruption of a series of immunopathological events, including the production of immunoglobulin E, release of histamine, and expression of prostaglandin-E2 and vascular endothelial growth factor-α in the sera and skin of the tested animals. Analysis of the cytokine expression in AD-like skin lesions further revealed that the NP-based formulation inhibited the pathological expression of interleukin (IL-4, IL-5, IL-6, IL-13, IL-12p70, interferon-γ, and tumor necrosis factor-α in serum and skin homogenates of NC/Nga mice. Further, our histological findings indicated that the NP-based formulation inhibited fibroblast infiltration and

    Full Text Available Context: Bullous allergic reactions are inflammatory skin disorders, presenting usually as a result of some type of reaction to medication. Case Report: A 67-year-old female was evaluated for the presence of diffuse patches of erythema, microvesiculation, vesicles, crusts, and oozing of sudden appearance on the extremities and on the rest of the body after taking sulfamethoxazole in combination with trimethoprim. Skin biopsies for hematoxylin and eosin examination, as well as for direct immunofluorescence and immunohistochemistry analysis were performed. H&E staining demonstrated classic features. Direct immunofluorescence revealed strong deposits of fibrinogen in the vessels of the skin. The immunohistochemistry stain showed strong positivity of myeloperoxidase within the blister cavity. The distribution of the vessels around the inflammatory process were noticed by using antibodies to CD34 as well to collagen IV. Conclusions: sulfamethoxazole is catalysed by CYP2C9 and/or myeloperoxidase. Thus, myeloperoxidase appears to be of importance in this disorder.

    Pemphigus and pemphigoid are different types of autoimmune bullous disease and can occur in the same patient. We report a female patient with this condition. At first, we diagnosed her with bullous pemphigoid, and we treated her with tetracycline, niacinamide and a topical steroid. Tense bullas disappeared shortly after that, but crusted erythemas mainly on her head and trunk persisted. We examined BP180 and desmoglein 1 enzyme-linked immunosorbent assays, and also histological features, which showed coexistence of bullous pemphigoid and pemphigus foliaceus concurrently. Therefore, we tried prednisolone, which could control both conditions. This case showed that tetracycline and niacinamide could control bullous pemphigoid, but could not control pemphigus foliaceus, and that prednisolone was effective for both conditions.

    Bullous mastocytosis is an unusual expression of mastocytosis typically seen in young children, and many causes of the acute mast cell degranulation with bulla formation have been identified. We report a 6-month-old boy with urticaria pigmentosa and an extensive bullous eruption associated with the ingestion of a nonprescription cough suppressant containing dextromethorphan. The pathogenesis of mastocytosis and the care of patients with this disease are discussed. PMID:8893244

    Despite the use of high-dose systemic corticosteroids in combination with other immunosuppressants, in some patients with autoimmune bullous diseases only insufficient improvement is achieved. In these cases and in acute severe disease, adjuvant immunoapheresis has been increasingly used. A consensus meeting was held in mid-2005 in Hamburg, aiming at developing guidelines for the use of immunoapheresis in the treatment of autoimmune bullous diseases. This paper summarizes the experts' recommendations. PMID:17910670

    2015-05-01

    Full Text Available In patients presenting with severe dyspnea, several diagnostic challenges arise in distinguishing the diagnosis of pneumothorax versus several other pulmonary etiologies like bullous lung disease, pneumonia, interstitial lung disease, and acute respiratory distress syndrome. Distinguishing between large pulmonary bullae and pneumothorax is of the utmost importance, as the acute management is very different. While multiple imaging modalities are available, plain radiographs may be inadequate to make the diagnosis and other advanced imaging may be difficult to obtain. Ultrasound has a very high specificity for pneumothorax. We present a case where a large pulmonary bleb mimics the lung point and therefore inaccurately suggests pneumothorax.

    Full Text Available Introduction: Proteinases and proteinase inhibitors have been described to play a role in autoimmune skin blistering diseases. We studied skin lesional biopsies from patients affected by several autoimmune skin blistering diseases for proteinases and proteinase inhibitors. Methods: We utilized immunohistochemistry to evaluate biopsies for alpha-1-antitrypsin, human matrix metalloproteinase 9 (MMP9, human tissue inhibitor of metalloproteinases 1 (TIMP-1, metallothionein and urokinase type plasminogen activator receptor (uPAR. We tested 30 patients affected by endemic pemphigus, 30 controls from the endemic area, and 15 normal controls. We also tested 30 biopsies from patients with bullous pemphigoid (BP, 20 with pemphigus vulgaris (PV, 8 with pemphigus foliaceus, and 14 with dermatitis herpetiformis (DH. Results: Contrary to findings in the current literature, most autoimmune skin blistering disease biopsies were negative for uPAR and MMP9. Only some chronic patients with El Bagre-EPF were positive to MMP9 in the dermis, in proximity to telocytes. TIMP-1 and metallothionein were positive in half of the biopsies from BP patients at the basement membrane of the skin, within several skin appendices, in areas of dermal blood vessel inflammation and within dermal mesenchymal-epithelial cell junctions.

    Full Text Available Context: Bullous pemphigoid is mediated by autoantibodies primarily targeting two structural proteins of basement membrane hemidesmosomes, BP180 (BPAG2; collagen XVII and BP230 (BPAG1. Case Report: A 70-year-old Caucasian male patient was evaluated for a seven day history of multiple itching, erythematous blisters on his extremities. Biopsies for hematoxylin and eosin examination, direct immunofluorescence and indirect immunofluorescence (including salt split skin analysis were performed. Results: Hematoxylin and eosin examination demonstrated a subepidermal blister. Within the blister lumen, numerous eosinophils and lymphocytes were noted. Direct and indirect immunofluorescence revealed linear deposits of IgG, Complement/C3 and fibrinogen at the basement membrane zone of the skin and surrounding selected dermal blood vessels and sweat glands. Positive intracytoplasmic staining for anti-human IgD was noted in most of the epidermis, as well as surrounding some dermal blood vessels. Indirect immunofluorescence utilizing monkey esophagus substrate demonstrated strong positivity within the endomysium for IgG antibodies. Conclusion: We report a unique case of bullous pemphigoid with reactivity to eccrine sweat glands, and selected dermal blood vessels. In addition, the observed reactivity of anti-human IgD, and of IgG to monkey esophagus endomysium warrant further investigation.

    Sarcoidosis is characterized by formation of epithelioid-cell tubercules, without caseation, of the affected organ systems. The mediastinum, peripheral lymph nodes and eyes, in addition to the skin, are most frequently affected. Between 10% and 30% of patients with systemic sarcoidosis in Japan have skin lesions. Skin sarcoidosis is morphologically classified into three basic groups, erythema nodosum, scar sarcoidosis and skin sarcoid. Skin sarcoid is characterized by specific cutaneous lesions of sarcoidosis, and may take nodular, plaque, angiolupoid, subcutaneous and some other forms. Clinical manifestations of the cutaneous lesions are usually asymptomatic and polymorphous. Skin biopsy is, however, often highly useful for confirming a diagnosis of sarcoidosis.

    Full Text Available Introduction: The in situ immune response in skin biopsies from patients affected by autoimmune skin blistering diseases (ABD is not well characterized. Aim: Our investigation attempts to immunophenotype cells in lesional skin in several ABD, utilizing immunohistochemistry (ICH. Methods: We tested by IHC for CD4, CD8, CD19, CD20, CD45, CD56/NCAM, PAX-5, granzyme B, myeloperoxidase, neutrophil elastase, LAT and ZAP-70 in patients affected by ABD. We tested 30 patients with endemic pemphigus foliaceus (EPF, 15 controls from the EPF endemic area, and 15 biopsies from healthy controls from the USA. We also tested archival biopsies from patients with selected ABD, including 30 patients with bullous pemphigoid, 20 with pemphigus vulgaris, 8 with pemphigus foliaceus and 14 with dermatitis herpetiformis. Results: We found a predominantly CD8 positive/CD45 positive T cell infiltrate in all ABD. Our skin biopsies demonstrated consistently positive staining for myeloperoxidase, but negative staining for neutrophil elastase. Most ABD biopsies displayed negative staining for CD4 and B cell markers; natural killer cell markers were also rarely seen. ZAP-70 and LAT were frequently detected. In El Bagre-EPF, a significant fragmentation of T cells in lesional skin was noted, as well as autoreactivity to lymph nodes. Conclusions: The documented T cell and myeloperoxidase staining are indicative of the role of T lymphocytes and neutrophils in lesional biopsies in patients with ABD, in addition to previously documented deposition of B cells, immunoglobulins and complement in situ. In El Bagre-EPF, T cells could also target lymph nodes; however, further studies are needed to confirm this possibility.

    Today, subject's medical data in controlled clinical trials is captured digitally in electronic case report forms (eCRFs). However, eCRFs only insufficiently support integration of subject's image data, although medical imaging is looming large in studies today. For bed-side image integration, we present a mobile application (App) that utilizes the smartphone-integrated camera. To ensure high image quality with this inexpensive consumer hardware, color reference cards are placed in the camera's field of view next to the lesion. The cards are used for automatic calibration of geometry, color, and contrast. In addition, a personalized code is read from the cards that allows subject identification. For data integration, the App is connected to an communication and image analysis server that also holds the code-study-subject relation. In a second system interconnection, web services are used to connect the smartphone with OpenClinica, an open-source, Food and Drug Administration (FDA)-approved electronic data capture (EDC) system in clinical trials. Once the photographs have been securely stored on the server, they are released automatically from the mobile device. The workflow of the system is demonstrated by an ongoing clinical trial, in which photographic documentation is frequently performed to measure the effect of wound incision management systems. All 205 images, which have been collected in the study so far, have been correctly identified and successfully integrated into the corresponding subject's eCRF. Using this system, manual steps for the study personnel are reduced, and, therefore, errors, latency and costs decreased. Our approach also increases data security and privacy.

    Jorge Lobo's disease (JLD) is a chronic granulomatous mycosis described in various Latin American countries. The main objective of the present study was to investigate the possible role of Th17 and Foxp3+ Treg cells in the pathogenesis of Jorge Lobo's disease. Human skin biopsies were submitted to an immunohistochemistry protocol to detect Foxp3, interleukin (IL)-1beta, CD25, IL-6, IL-17, and IL-23. The epidermis presented acanthosis, hyperkeratosis, and frequent presence of fungi. The dermis presented inflammatory infiltrate comprising macrophages, lymphocytes, epithelioid and multinucleated cells, and an intense number of fungi. Foxp3+ Treg cells and IL-17+ cells were visualized in lymphocytes in the inflammatory infiltrate. IL-1, IL-2R (CD25), IL-6, and IL-23 were visualized in the dermis, intermingled with fungal cells, permeating or participating of the granuloma. Following IL-17, the most prominent cytokine was IL-6. IL-23 and cells expressing CD25 were present in fewer number. The comparative analysis between IL-17 and Foxp3 demonstrated a statistically significant increased number of IL-17+ cells. Th17 cells play a role in the immune response of JLD. IL-1beta and IL-6 added to the previously described increased number of TGF-beta would stimulate such pattern of response. Th17 cells could be present as an effort to modulate the local immune response; however, high levels of a Th17 profile could overcome the role of Treg cells. The unbalance between Treg/Th17 cells seems to corroborate with the less effective immune response against the fungus.

    Smilacis Chinae Rhizome (SCR) has been used as an oriental folk medicine for various biological activities. However, its effect on atopic dermatitis (AD) remains undetermined to date. We assessed the effect of orally administered hot-water extract of SCR on AD-like skin lesions in mice and its underlying mechanisms. AD-like murine model was prepared by repeated alternate application of house dust mite (Dermatophagoides farinae) extract (DFE) and 2,4-dinitrochlorobenzene (DNCB) for 4 weeks, topically to the ears. Daily oral administration of SCR for 3 and 4 weeks significantly reduced inflammatory ear thickening, with the effect being enhanced at the earlier start and longer period of administration. This effect was accompanied by a significant decrease in both Th2 and Th1 serum antibodies (total IgE, DFE-specific IgE, and IgG2a). Histological analysis showed that SCR markedly decreased the epidermal/dermal ear thickening and the dermal infiltration of inflammatory cells. Furthermore, SCR suppressed DFE/DNCB-induced expression of IL-4, IL-13, IL-17, IL-18, TSLP, and IFN-γ genes in the ear tissue. Taken together, our observations demonstrate that chronic oral administration of SCR exerts beneficial effect in mouse AD model, suggesting that SCR has the therapeutic potential as an orally active treatment of AD by modulating both Th1 and Th2 responses.

    The clinical course of infection with Mycobacterium leprae varies widely and depends on the pattern of the host immune response. Dendritic cells play an important role in the activation of the innate and adaptive immune system and seem to be essential for the development of the disease. To analyze the presence of epidermal dendritic cells (CD1a and CD207), plasmacytoid dendritic cells (CD123) and dermal dendrocytes (factor XIIIa) in lesion fragments of leprosy patients, skin samples from 30 patients were studied. These samples were submitted to immunohistochemistry against CD1a, CD207, FXIIIa, and CD123. The results showed a larger number of Langerhans cells, detected with the CD1a or CD207 marker, dermal dendrocytes and plasmacytoid dendritic cells in patients with the tuberculoid form. A positive correlation was observed between the Langerhans cell markers CD1a and CD207 in both the tuberculoid and lepromatous forms, and between Langerhans cells and dermal dendrocytes in samples with the tuberculoid form. The present results indicate the existence of a larger number of dendritic cells in patients at the resistant pole of the disease (tuberculoid) and suggest that the different dendritic cells studied play a role, favoring an efficient immune response against infection with M. leprae.

    Full Text Available Natural killer (NK cells were proposed to play an important role in the pathogenesis of human T-cell lymphotropic virus type 1- (HTLV-1- associated neurologic disease. Our patient was a 77-year-old Japanese man, who had been treated for infective dermatitis associated with HTLV-1 for nearly 10 years. When referred to us, he had facial eczema/edema as well as extensive dermatitis at the neck/upper chest and nuchal area/upper back regions. Dermal lesions had CD3+CD4+ cells, but no NK cells. Flow cytometry of his peripheral blood showed a phenotype of CD2+ (97%, CD3+ (17%, CD4+ (12%, CD7+ (94%, CD8+ (6%, CD11c+ (70%, CD16+ (82%, CD19+ (0%, CD20+ (0%, CD56+ (67%, HLA-DR+ (68%, and NKp46+ (36%. Absolute numbers of CD56+NK cells in the peripheral blood were in a range of 986/μL–1,270/μL. The expanded NK cells in the peripheral blood are considered to be reactive, to maintain the confinement of the HTLV-1-positive CD4+ cells in the skin, and to prevent the progression of the disease.

    Full Text Available Sanguisorbae Radix (SR is well known as herbal medicine named “Zi-Yu” in Korea, which is the dried roots of Sanguisorba officinalis L. (Rosacease. We investigated the underlying mechanism on the inhibition of atopic dermatitis (AD of an ethanol extract of SR (ESR using 2,4-dinitrochlorobenzene- (DNCB- induced AD mice model. Oral administration of ESR significantly suppressed DNCB-induced AD-like symptoms such as scratching behavior, ear thickness, epidermal thickness, and IgE levels. To investigate the effects of ESR treatment on degranulation of IgE/Ag-activated mouse bone marrow-derived mast cells (BMMCs, we measured the release of β-hexosaminidase (β-HEX, degranulation marker. ESR decreased the infiltration of eosinophils and mast cells into the AD skin lesions. Furthermore, ESR significantly inhibited degranulation of IgE/Ag-activated BMMCs. We have demonstrated that ESR decreased AD symptoms in mice and inhibits degranulation of IgE/Ag-activated mast cells. Our study suggests that ESR may serve as a potential therapeutic candidate for the treatment of AD symptoms.

    Toxic epidermal necrolysis (TEN) is an adverse reaction that can be induced by various drugs; the associated mortality rate is 20-25%. A previous report showed a weak association between TEN and acetaminophen. Recently, the US Food and Drug Administration declared that acetaminophen is associated with a risk of serious skin reactions, including TEN. Here, we describe the case of a 43-year-old Japanese woman with TEN caused by acetaminophen. She had poorly controlled ulcerative colitis and was treated with high doses of prednisolone, infliximab, acetaminophen and lansoprazole. Nine days after administrating acetaminophen, targetoid erythematous and bullous lesions appeared on the patient's trunk, palms and the soles of her feet. The skin lesions expanded rapidly; within 3 weeks, skin detachment was detected across nearly 100% of the patient's body. However, no mucosal involvement of the eyes, oral cavity or genitalia was found. We performed lymphocyte transformation tests using various drugs; however, a high stimulation index was obtained only with acetaminophen. The patient recovered following treatment with plasmapheresis, i.v. immunoglobulin therapy, topical medication and supportive therapy. Acetaminophen is included in many prescription and over-the-counter products; thus, clinicians should monitor their patients for severe drug reactions, including TEN. PMID:26362011

    Full Text Available Abstract Background Suspicious pigmented lesions are a common presenting problem in general practice consultations; while the majority are benign a small minority are melanomas. Differentiating melanomas from other pigmented lesions in primary care is challenging: currently, 95% of all lesions referred to a UK specialist are benign. The MoleMate system is a new diagnostic aid, incorporating a hand-held SIAscopy scanner with a primary care diagnostic algorithm. This trial tests the hypothesis that adding the MoleMate system to current best primary care practice will increase the proportion of appropriate referrals of suspicious pigmented lesions to secondary care compared with current best practice alone. Methods/design The MoleMate UK Trial is a primary care based multi-centre randomised controlled trial, with randomisation at patient level using a validated block randomisation method for two age groups (45 years and under; 46 years and over. We aim to recruit adult patients seen in general practice with a pigmented skin lesion that cannot immediately be diagnosed as benign and the patient reassured. The trial has a 'two parallel groups' design, comparing 'best practice' with 'best practice' plus the MoleMate system in the intervention group. The primary outcome is the positive predictive value (PPV of referral defined as the proportion of referred lesions seen by secondary care experts that are considered 'clinically significant' (i.e. biopsied or monitored. Secondary outcomes include: the sensitivity, specificity and negative predictive value (NPV of the decision not to refer; clinical outcomes (melanoma thickness, 5 year melanoma incidence and mortality; clinician outcomes (Index of Suspicion, confidence, learning effects; patient outcomes (satisfaction, general and cancer-specific worry, and cost-utility.

    Human epidermis is a squamous stratified epithelium whose integrity relies on balanced processes of cell attachment, proliferation, and differentiation. In monogenic skin dermatoses, such as mecano-bullous diseases, or DNA repair deficiencies such as the xeroderma pigmentosum (XP), alterations of skin integrity may have devastating consequences as illustrated by the extremely high epidermal cancer proneness of XP patients. The lack of efficient pharmacological treatments, the easy accessibility of skin, and the possibility of long term culture and genetic manipulations ex vivo of epidermal keratinocytes, have encouraged approaches toward gene transfer and skin therapy prospects. We review here some of the human genetic disorders that exhibit major traits in skin, as well as requirements and difficulties inherent to approaches aimed at stable phenotypic correction.

     Herpes zoster is a painful disease that can develop in immunosuppressed children. Prolonged immunosuppression in leukemia patients can substantially delay healing of herpetic lesions. The purpose of this report was to evaluate the use of hemicellulose dressings as an alternative treatment for extensive herpetic lesions in an immunosuppressed child with leukemia. The hemicellulose dressing was applied to the lesions on the second day after debridement. After 36 days, the lesions were completely healed. The hemicellulose dressing was an effective resource for promoting complete epithelial healing.

    Full Text Available Coagulation activation has been demonstrated in two prototypic autoimmune skin diseases, chronic autoimmune urticaria and bullous pemphigoid, but only the latter is associated with increased thrombotic risk. Two markers of coagulation activation (prothrombin fragment F1+2 and fibrin fragment D-dimer were measured by immunoenzymatic methods in plasma samples from 30 patients with active chronic autoimmune urticaria, positive for autologous serum skin test, 30 patients with active bullous pemphigoid and 30 healthy subjects. In skin biopsies, tissue factor expression was evaluated by both immunohistochemistry and in situ hybridization. F1+2 and D-dimer levels were higher in active chronic autoimmune urticaria (276.5±89.8 pmol/L and 5.56±4.40 nmol/L, respectively than in controls (145.2±38.0 pmol/L and 1.06±0.25 nmol/L; P=0.029 and P=0.011 and were much higher in active bullous pemphigoid (691.7±318.7 pmol/L and 15.24±9.09 nmol/L, respectively (P<0.0001. Tissue factor positivity was evident in skin biopsies of both disorders with higher intensity in bullous pemphigoid. F1+2 and D-dimer, during remission, were markedly reduced in both disorders. These findings support the involvement of coagulation activation in the pathophysiology of both diseases. The strong systemic activation of coagulation in bullous pemphigoid may contribute to increase the thrombotic risk and provides the rationale for clinical trials on anticoagulant treatments in this disease.

    Combination therapy is often used in the treatment of atopic dermatitis (AD) to improve clinical efficacy or to spare the dose of each drug. Cyclosporine A (CsA) is a calcineurin inhibitor that was developed for the treatment of AD. Glucosamine (Glu) is a potent immunosuppressant that inhibits Th2-mediated immunity. We previously reported that Glu has an ameliorative effect on the development of the pathology in NC/Nga mice. The aims of our study were to investigate the therapeutic efficacy of combination of Glu and low-dose CsA in dermatophagoides farina (Df)-induced AD-like skin lesions in NC/Nga mice and to determine the underlying therapeutic mechanisms. The Df-induced NC/Nga mice with a clinical score of 7 were used for treatment with Glu (500mg/kg) alone, low-dose CsA (2, 5, and 10mg/kg) or in combination. The clinical scores were reduced significantly by the combination treatment with Glu and low-dose CsA. The suppression of dermatitis by combined therapy was accompanied by decrease in the plasma level of IgE and in the splenic level of IL-4, IL-5, IL-13, TARC and eotaxin. Histological analysis of the skin also revealed that combination treatment significantly reduced the inflammatory cellular infiltrate, including mast cells and eosinophils. Particularly, immunological evaluation reveals an increase of CD4(+)CD25(+) Treg cells in the combined treatment. The induction of TSLP, which leads to systemic Th2 response, was reduced in the skin on combination treatment. The protein expression of filaggrin and involucrin was recovered by combination treatment in the skin lesions, whereas the protein expression of keratin-10 and keratin-14 decreased in the combination treatment. Collectively, our findings suggest that combination treatment of Glu and low-dose CsA leads to the therapeutic effects in Df-induced AD-like skin lesion in NC/Nga mice through inhibition of IgE, inflammatory cellular infiltrate, and recovery of skin barrier function via a mechanism that may

CONCLUSÃO: o método clínico baseado no número de lesões cutâneas para classificação dos pacientes hansenianos apresenta limitações que não invalidam sua operacionalidade, porém novos critérios devem ser desenvolvidos possibilitando uma melhor acurácia na alocação dos pacientes nos esquemas poliquimioterápicos.BACKGROUND: The integration of leprosy control programs into the basic health system led to the updating of norms in legislation regarding control of the disease. The operational classification adopted for allocating patients for an appropriate multidrug therapy is the one recommended by the World Health Organization (WHO; it is essentially clinical, based on the number of skin lesions. Cases with up to 5 skin lesions are considered paucibacillary (PB and with more than 5 skin lesions are multibacillary (MB. OBJETIVES: The results of skin smears were correlated to the number of skin lesions, with the objective of evaluating the clinical method of classification. METHODS: The source of information was the data bank where detailed epidemiological, clinical and laboratory information on patients is kept. Data referring to the skin smears of 837 cases from 1986 to 1999 were collected. The criteria were to analyze, using the standard reference method, the number of lesions compared to the results of the skin smear exams. From this comparison, a calculation was made of the relative sensitivity and specificity as well as the positive and negative predictive values using the criterion of cutaneous lesions to evaluate the agreement between the number of lesions and the skin smear calculated by means of the kappa index (k. RESULTS: Of the 837 cases evaluated, 652 presented positive skin smears and 185 negative. Thirty (16.0% of the patients with negative skin smears presented more than 5 skin lesions. Among the 652 patients with positive skin smears, 68 (11.4% presented less than 5 skin lesions. Regarding

    Full Text Available Background: Many countries have conducted studies on the benefits of phototherapeutic keratectomy in corneal diseases; few references have been found in our country to address the results of the application of the excimer laser in the elderly suffering from bullous keratopathy. Objective: To assess the results of the application of phototherapeutic keratectomy in the eldrly with bullous keratopathy. Methods: A case series study was conducted in 2009, in the Cornea Department of the Dr. Gustavo Aldereguía Lima General University Hospital of Cienfuegos. It included 16 elderly with bullous keratopathy not leading to penetrating keratoplasty. After considering the ethical and biomedical assessment, phototherapeutic keratectomy was performed. Treatment was indicated and follow up was performed with an assessment of symptoms and signs until the third month. Results: In the postoperative stage symptoms decreased and the most frequent sign was the haze followed by slight increase in best corrected visual acuity. Conclusions: The application of phototherapeutic keratectomy in patients that did not apply for cornea transplant helps improving eye condition, reduces symptoms and improves visual acuity.

    2016-03-01

    Multifocal vascular lesions are important to recognize and appropriately diagnose. Generally first noticed on the skin, multifocal vascular lesions may have systemic involvement. Distinguishing among the different types of multifocal vascular lesions is often based on clinical features; however, radiological imaging and/or biopsy are frequently needed to identify distinct features and guide treatment. Knowledge of the systemic associations that can occur with different vascular anomalies may reduce life-threatening complications, such as coagulopathy, bleeding, cardiac compromise, and neurologic sequelae. This review provides a synopsis of the epidemiology, pathogenesis, presentation, workup, and treatment of several well-recognized multifocal vascular tumors and malformations. PMID:27607324

    Full Text Available Background and Design: Bullous pemphigoid (BP is an autoimmune disease characterised by widespread itchy plaques and subepithelial blisterings and usually affects the elderly population. Due to the chronic nature of the disease, to prevent the side effects of chronic steroid treatment, adjuvant immunosuppressive (mycophenolate mofetil, azathioprine, methotrexate and anti-inflammatory (tetracycline, nicotinamide, dapsone agents may be used. In this study, we retrospectively evaluated the clinical and demographic characteristics and applied treatments of 46 patients with the diagnosis of BP and compared with literature data. Materials and Methods: We retrospectively evaluated the records of 46 patients who received clinical and histopathological diagnosis of BP and followed up in our clinic between 2006 and 2013. Results: Of the 46 patients, 22 were female and 24 male. The mean age of onset was 69.54 years (range: 18-105. The duration of the lesion ranged from 1 week to 10 months with a median duration of 8 weeks. The most frequent comorbid chronic disease was hypertension detected in 28 (60.8% patients. Only four patients had a history of malignancy before the onset of the disease. Nineteen patients (42% used more than 5 agents for comorbid diseases. Thirty-two patients (69.5% used systemic corticosteroids alone and ten (22% patients needed additional adjuvant therapies. Conclusion: BP is a major cause of morbidity in the elderly population receiving multiple drug treatment. To avoid the side effects of steroid therapy, especially in patients with severe disease, short-term use of additional immunosuppressive agents appears to be safe and effective.

    A total of 2402 patients with arsenic-related skin lesions, such as hyperkeratosis, hyperpigmentation or hypopigmentation, or even skin cancer in a few villages in Southwest Guizhou Autonomous Prefecture, China represent a unique case of endemic arsenism related with indoor combustion of high arsenic coal. This study aimed to investigate the cluster of arsenism cases and the possible relevant factors including GSTP1 polymorphism in two clans of different ethnic origin living in one village for generations. Arsenism morbidity in Miao clan P was significantly lower than in the neighbouring Han clan G1 (5.9 vs. 32.7%, odds ratio (OR)=0.13, 95% confidence interval (CI): 0.06-0.27, P < 0.0001). No sex differences were confirmed inside both clans. Analyses of the environmental samples indicated that Miao clan P members were exposed to higher amounts of arsenic via inhalation and food ingestion. Hair and urine samples also proved a higher arsenic body burden in ethnic Miao individuals. No corresponding differences by sex were found. Higher frequencies of combined mutant genotype G/G1578 and A/G1578 (OR=4.72, 95% CI: 2.34-9.54, P < 0.0001) and of mutant allele G1578 (OR=3.22, 95% CI: 2.00-5.18, P < 0.0001) were detected in diagnosed arsenism patients than in non-diseased individuals. The Miao individuals showed a lower percentage of combined mutant genotypes (30.6 vs. 52.7%, OR=0.40, 95% CI: 0.19-0.84, P=0.015) as well as of mutant allele G1578 (OR=0.46, 95% CI: 0.24-0.88, P=0.017) than their Han neighbours. Conclusions Genetic predisposition influences dermal arsenism toxicity. The GSTP1 A1578G (IIe105Val) status might be a susceptibility factor for arsenic-related skin lesions.

    Full Text Available Radiation therapy is associated with a variety of complications, including the development of primary skin cancers in the radiated region. However, it is rare for patients with visceral cancers who are treated with radiation therapy to subsequently develop cutaneous metastasis within the radiation port. We describe two patients with internal malignancies who developed cutaneous metastases within their radiation ports following radiotherapy. In addition, we used PubMed to perform an extensive literature review and identify additional reports of cutaneous metastasis within a radiation port. We excluded patients who developed melanoma or primary skin cancers in the radiation port. We also excluded patients with non-solid organ malignancies. Herein, we summarize the characteristics of 23 additional patients who experienced radiation port cutaneous metastases and explore possible mechanisms for the occurrence of radiation port cutaneous metastases.

  11. Arsenic exposure at low-to-moderate levels and skin lesions, arsenic metabolism, neurological functions, and biomarkers for respiratory and cardiovascular diseases: Review of recent findings from the Health Effects of Arsenic Longitudinal Study (HEALS) in Bangladesh

    International Nuclear Information System (INIS)

    The contamination of groundwater by arsenic in Bangladesh is a major public health concern affecting 35-75 million people. Although it is evident that high levels (> 300 μg/L) of arsenic exposure from drinking water are related to adverse health outcomes, health effects of arsenic exposure at low-to-moderate levels (10-300 μg/L) are not well understood. We established the Health Effects of Arsenic Longitudinal Study (HEALS) with more than 20,000 men and women in Araihazar, Bangladesh, to prospectively investigate the health effects of arsenic predominately at low-to-moderate levels (0.1 to 864 μg/L, mean 99 μg/L) of arsenic exposure. Findings to date suggest adverse effects of low-to-moderate levels of arsenic exposure on the risk of pre-malignant skin lesions, high blood pressure, neurological dysfunctions, and all-cause and chronic disease mortality. In addition, the data also indicate that the risk of skin lesion due to arsenic exposure is modifiable by nutritional factors, such as folate and selenium status, lifestyle factors, including cigarette smoking and body mass index, and genetic polymorphisms in genes related to arsenic metabolism. The analyses of biomarkers for respiratory and cardiovascular functions support that there may be adverse effects of arsenic on these outcomes and call for confirmation in large studies. A unique strength of the HEALS is the availability of outcome data collected prospectively and data on detailed individual-level arsenic exposure estimated using water, blood and repeated urine samples. Future prospective analyses of clinical endpoints and related host susceptibility will enhance our knowledge on the health effects of low-to-moderate levels of arsenic exposure, elucidate disease mechanisms, and give directions for prevention.

    Because psoriatic skin lesions of psoriatic arthritis (PsA) usually precede the onset of joint symptom, dermatologists are in an ideal position to screen and find individuals with PsA early in the disease course. There have been no reports from the dermatology field evaluating the effect of anti-tumor necrosis factor (TNF)-α drugs on joint disorders using magnetic resonance imaging (MRI) in PsA patients. The purpose of this study was to elucidate the effectiveness of MRI in the evaluation of anti-TNF-α drugs on joint disease of Japanese PsA patients. Data were collected from four adult Japanese male PsA patients. MRI of the affected hand was performed at baseline and 1-7 months after infliximab or adalimumab treatment. T1 -weighted gadolinium-enhanced images with fat suppression were acquired in the coronal, sagittal and/or axial planes. We determined the apparent improvement of synovitis, periarticular inflammation, tenosynovitis and/or bone marrow edema by MRI after anti-TNF-α treatments in all the patients together with the improvement of skin lesions. We also determined in one patient that these symptoms detected by MRI before treatment were alleviated within 1 month and had disappeared 6 months after treatment, suggesting the potentially early detection of the effect of anti-TNF-α drugs on joint disease. We present four cases of Japanese patients with PsA in whom effective treatments by anti-TNF-α drugs were evaluated by contrast-enhanced MRI. This imaging enables dermatologists and radiologists to assess and monitor early inflammatory changes, and to grant PsA patients earlier access to modern treatment such as biologics.

  13. Taenia taeniaeformis in rat favors protracted skin lesions caused by Sporothrix schenckii infection: Dectin-1 and IL-17 are dispensable for clearance of this fungus.

    Full Text Available We occasionally found that cestode Taenia taeniaeformis in rats favored Sporothrix schenckii infection and survival, causing protracted cutaneous lesions. In this study, we compared the pathology and cytokines profile of rats co-infected with the two pathogens and infected with S. schenckii alone to explore underlying mechanisms. In the co-infection group, there was high expression of β-glucan receptor Dectin-1 in the cutaneous lesions and no multinucleated giant cells, but in the S. schenckii infection group the opposite was observed. Cytokines profiles demonstrated an expected finding that IL-4, commonly expressed in helminth and fungus infection, is undetectable in the two infection groups. In the single fungal infection group, cytokines IFN-γ, IL-10 and IL-17 kept increasing in the first few weeks of infection to a peak which was followed by gradual decrease. This study showed that Dectin-1 and IL-17, which were believed to be the major anti-fungus mechanisms, are Th2 independent and dispensable for clearance of S. schenckii infection, suggesting that S. schenckii has a different molecular recognition pattern and evokes anti-infection mechanisms other than Dectin-1 and IL-17.

    Full Text Available We evaluated the preventive effects of four types of seawater collected in Republic of Korea on hairless mice with 2,4-dinitrochlorobenzene- (DNCB- induced allergic/atopic dermatitis (AD. The anti-inflammatory effects were evaluated by measuring tumor necrosis factor- (TNF- α and interleukins (ILs. Glutathione (GSH, malondialdehyde (MDA, superoxide anion, and inducible nitric oxide synthase (iNOS were measured to evaluate the antioxidant effects. Caspase-3 and poly (ADP-ribose polymerase (PARP were observed to measure the antiapoptotic effects; matrix metalloproteinase- (MMP- 9 levels were also evaluated. Mice with AD had markedly higher clinical skin severity scores and scratching behaviors; higher TNF-α and ILs (1β, 10, 4, 5, and 13 levels; higher MDA, superoxide anion, caspase-3, PARP, and MMP-9 levels; and greater iNOS activity. However, the severity of AD was significantly decreased by bathing in seawaters, but it did not influence the dermal collagen depositions and skin tissue antioxidant defense systems. These results suggest that bathing in all four seawaters has protective effects against DNCB-induced AD through their favorable systemic and local immunomodulatory effects, active cytoprotective antiapoptotic effects, inhibitory effects of MMP activity and anti-inflammatory and antioxidative effects.

    This work attempts to establish dermatological identification patterns for Brazilian cnidarian species and a probable correlation with envenoming severity. In an observational prospective study, one hundred and twenty-eight patients from the North Coast region of São Paulo State, Brazil were seen between 2002 and 2008. About 80% of these showed only local effects (erythema, edema, and pain) with small, less than 20 cm, oval or round skin marks and impressions from small tentacles. Approximately 20% of the victims had long, more than 20 cm, linear and crossed marks with frequent systemic phenomena, such as malaise, vomiting, dyspnea, and tachycardia. The former is compatible with the common hydromedusa from Southeast and Southern Brazil (Olindias sambaquiensis). The long linear marks with intense pain and systemic phenomena are compatible with envenoming by the box jellyfish Tamoya haplonema and Chiropsalmus quadrumanus and the hydrozoan Portuguese man-of-war (Physalis physalis). There was an association between skin marks and probable accident etiology. This simple observation rule can be indicative of severity, as the Cubozoa Class (box jellyfish) and Portuguese man-of-war cause the most severe accidents. In such cases, medical attention, including intensive care, is important, as the systemic manifestations can be associated with death. PMID:20305955

    Multi-glycoside of Tripterygium wilfordii Hook. f. (GTW) possesses anti-inflammatory and immunosuppressive properties, and has been used as a traditional treatment for psoriasis for many years, although the underlying immunological mechanisms remain poorly understood. The T helper (Th)17 cell response is considered to play a major role in the pathogenesis of psoriasis. Th17 cells are implicated in the mechanism of pathogenesis of imiquimod (IMQ)-induced skin inflammation. Using a mouse model, we demonstrated that GTW protected mice from developing psoriasis-like lesions induced by topical IMQ administration. This protection was associated with significantly decreased mRNA levels of Th17 cytokines such as interleukin (IL)-17A, IL-17F and IL-22 in mouse skin samples as well as fewer IL-17-secreting splenic CD4+ lymphocytes in IMQ-exposed mice. There were no significant effects on the proportion of CD4+ interferon (IFN)-γ+ T cells, CD4+IL-4+ T cells and CD4+CD25+Foxp3+ Treg cells in the spleen cells. Taken together with the unchanged mRNA levels of Th1 cytokine IFN-γ, Th2 cytokine IL-4 and Treg cytokine IL-10 in IMQ-exposed mouse skin following GTW administration, our findings suggest that the immunosuppressive effect of GTW in psoriasis is exerted mainly on Th17 cells, rather than on Th1, Th2 or Treg cells. Furthermore, we showed that GTW suppressed Th17 function through the inhibition of STAT3 phosphorylation. These results have the potential to pave the way for the use of GTW as an agent for the treatment of psoriasis. PMID:27431437

    Psoriasis is a multifactorial skin disease that inconveniences many patients. Considering the side effects and drug resistance of the current therapy, it is urgent to discover more effective and safer anti-psoriatic drugs. In the present study, we screened over 250 traditional Chinese medicine compounds for their ability to inhibit the cell viability of cultured human HaCaT keratinocytes, a psoriasis-relevant in vitro model, and found that periplogenin was highly effective. Mechanistic studies revealed that apoptosis and autophagy were not induced by periplogenin in HaCaT cells. However, periplogenin caused PI to permeate into cells, increased lactate LDH release and rapidly increased the number of necrotic cells. Additionally, the typical characteristics of necrosis were observed in the periplogenin-treated HaCaT cells. Notably, the necroptosis inhibitor Nec-1 and NSA were able to rescue the cells from necrotic cell death, supporting that necroptosis was involved in periplogenin-induced cell death. Furthermore, the ROS levels were elevated in the periplogenin-treated cells, NAC (an antioxidant) and Nec-1 could inhibit the ROS levels, and NAC could attenuate necroptotic cell death, indicating that the periplogenin-induced necroptotic cell death was mediated by oxidative stress. More importantly, in the murine models of TPA-induced epidermal hyperplasia and IMQ-induced skin inflammation, topical administration of periplogenin ameliorated skin lesions and inflammation. In sum, our results indicate, for the first time, that periplogenin is a naturally occurring compound with potent anti-psoriatic effects in vitro and in vivo, making it a promising candidate for future drug research.

    Full Text Available Access to laboratory diagnosis can be a challenge for individuals suspected of Buruli Ulcer (BU. Our objective was to develop a clinical score to assist clinicians working in resource-limited settings for BU diagnosis.Between 2011 and 2013, individuals presenting at Akonolinga District Hospital, Cameroon, were enrolled consecutively. Clinical data were collected prospectively. Based on a latent class model using laboratory test results (ZN, PCR, culture, patients were categorized into high, or low BU likelihood. Variables associated with a high BU likelihood in a multivariate logistic model were included in the Buruli score. Score cut-offs were chosen based on calculated predictive values. Of 325 patients with an ulcerative lesion, 51 (15.7% had a high BU likelihood. The variables identified for the Buruli score were: characteristic smell (+3 points, yellow color (+2, female gender (+2, undermining (+1, green color (+1, lesion hyposensitivity (+1, pain at rest (-1, size >5cm (-1, locoregional adenopathy (-2, age above 20 up to 40 years (-3, or above 40 (-5. This score had AUC of 0.86 (95%CI 0.82-0.89, indicating good discrimination between infected and non-infected individuals. The cut-off to reasonably exclude BU was set at scores <0 (NPV 96.5%; 95%CI 93.0-98.6. The treatment threshold was set at a cut-off ≥4 (PPV 69.0%; 95%CI 49.2-84.7. Patients with intermediate BU probability needed to be tested by PCR.We developed a decisional algorithm based on a clinical score assessing BU probability. The Buruli score still requires further validation before it can be recommended for wide use.

  1. A Luciferase-Expressing Leishmania braziliensis Line That Leads to Sustained Skin Lesions in BALB/c Mice and Allows Monitoring of Miltefosine Treatment Outcome.

    Full Text Available Leishmania braziliensis is the most prevalent species isolated from patients displaying cutaneous and muco-cutaneous leishmaniasis in South America. However, there are difficulties for studying L. braziliensis pathogenesis or response to chemotherapy in vivo due to the natural resistance of most mouse strains to infection with these parasites. The aim of this work was to develop an experimental set up that could be used to assess drug efficacy against L. braziliensis. The model was tested using miltefosine.A L. braziliensis line, originally isolated from a cutaneous leishmaniasis patient, was passaged repeatedly in laboratory rodents and further genetically manipulated to express luciferase. Once collected from a culture of parasites freshly transformed from amastigotes, 106 wild type or luciferase-expressing stationary phase promastigotes were inoculated subcutaneously in young BALB/c mice or golden hamsters. In both groups, sustained cutaneous lesions developed at the site of inoculation, no spontaneous self- healing being observed 4 months post-inoculation, if left untreated. Compared to the wild type line features, no difference was noted for the luciferase-transgenic line. Infected animals were treated with 5 or 15 mg/kg/day miltefosine orally for 15 days. At the end of treatment, lesions had regressed and parasites were not detected. However, relapses were observed in animals treated with both doses of miltefosine.Here we described experimental settings for a late-healing model of cutaneous leishmaniasis upon inoculation of a luciferase-expressing L. braziliensis line that can be applied to drug development projects. These settings allowed the monitoring of the transient efficacy of a short-term miltefosine administration.

    Junctional epidermolysis bullosa (JEB) is a heterogeneous autosomal recessively inherited blistering skin disorder associated with fragility at the dermal-epidermal junction. Characteristic ultrastructural findings in JEB are abnormalities in the hemidesmosome-anchoring filament complexes. These focal attachment structures, which extend from the intracellular compartment of the basal keratinocytes to the underlying basement membrane, have been shown to be hypoplastic or rudimentary in different forms of JEB. Previously, in different JEB phenotypes, mutations have been found in the three genes for the anchoring filament component laminin 5 (LAMA3, LAMB3, and LAMC2) and in the gene for the hemidesmosome-associated integrin beta 4 subunit. Here, we describe the first mutations in the gene encoding the 180-kD bullous pemphigoid antigen (BPAG2), a transmembranous hemidesmosomal collagen, also known as type XVII collagen (COL17A1). The patient is affected with generalized atrophic benign epidermolysis bullosa (GABEB), a rare variant of JEB, and is a compound heterozygote for premature termination codons on both alleles. These novel findings emphasize the molecular heterogeneity of this group of genodermatoses, and attest to the importance of BPAG2 in maintaining adhesion between the epidermis and the dermis.

    An association between mixed cryoglobulinaemia (MC) and hepatotropic viruses, chiefly hepatitis C virus (HCV), has been widely reported. The presence of HCV genomic sequences or HCV-related viral proteins in the serum, purified cryoglobulins, peripheral blood mononuclear cells and into several tissues has suggested an important triggering role for HCV in MC patients. However, only few reports investigated the presence of HCV in cutaneous vasculitis and its potential pathogenetic role. Biopsies of cutaneous purpuric lesions from 5 MC female patients (aged from 40 to 80 years) were carried out for virological and histopathological evaluation. A leukocytoclastic vasculitis pattern was found in 4/5 subjects, while the presence of HCV RNA was detected in 3/5. In only 3 cases biopsy specimens were sufficient for immunohistochemical and direct immunofluorescence (DIF) studies. Immunohistochemical evaluation was performed by means of alkaline phosphatase and monoclonal anti-alkaline phosphatase (APAAP) immune-complexes. In the same skin specimen APAAP and DIF findings were compared with the presence/absence of HCV genomic sequences (PCR technique). In 1 MC patient, the detection of HCV-RNA was associated to a prevalent CD8+ T suppressor pattern with a perivascular and subjunctional distribution as well as an intense expression of second class (HLA-DR) and intercellular adhesion (ICAM-1) molecules on basal keratinocytes, endothelial cells and perivascular infiltrate. These findings suggest a marked inflammatory activation that spreads from endothelial cells to keratinocytes and Langerhans cells. In the 2 HCV-RNA negative specimens the scanty immunopathological staining could indicate a residual activity due to the previous inflammatory event triggered by cryoglobulins. The deposition of circulating HCV-containing immune complexes (CIC) in the skin could be the initial pathogenic event for cryoglobulinemic vasculitis; subsequently CIC could spread from the vascular bed to

    Our scientific knowledge of bullous pemphigoid (BP) has dramatically progressed in recent years. However, despite the availability of various therapeutic options for the treatment of inflammatory diseases, only a few multicenter controlled trials have helped to define effective therapies in BP. A major obstacle in sharing multicenter-based evidences for therapeutic efforts is the lack of generally accepted definitions for the clinical evaluation of patients with BP. Common terms and end points of BP are needed so that experts in the field can accurately measure and assess disease extent, activity, severity, and therapeutic response, and thus facilitate and advance clinical trials. These recommendations from the International Pemphigoid Committee represent 2 years of collaborative efforts to attain mutually acceptable common definitions for BP and proposes a disease extent score, the BP Disease Area Index. These items should assist in the development of consistent reporting of outcomes in future BP reports and studies. PMID:22056920

    Full Text Available Immunodeficient patients are at risk of developing extended or atypical herpes simplex virus infections, which can be easily misdiagnosed. We present the case of a 79-year-old, treatment-induced (oral corticosteroid, immunocompromised female with an extensive atypical herpes simplex virus infection. This patient presented with multiple erosions and vesicles on the trunk with a subacute onset. The clinical differential diagnosis was herpes simplex infection, herpes zoster infection, pemphigus vulgaris or bullous pemphigoid. Due to the atypical clinical presentation and negative Tzanck test, suspicion of viral infection was low. High-dose steroid treatment was initiated. Subsequent histopathology, however, showed a herpes simplex virus infection. After discontinuing steroid treatment and initiating antiviral treatment, the patient recovered within a week. Emphasis must be placed on the importance of clinical awareness of extended and clinically atypical herpes simplex infections in immunocompromised patients. A negative Tzanck test does not rule out the possibility of a herpes infection.

    Full Text Available A case of a two-year-old male Pinscher with a history of discomfort in the right eye was reported. The left eye had been enucleated by the referring veterinarian due to the same symptom with unsuccessful clinical treatment. The Schirmer tear test value was elevated and a decreased intraocular pressure was observed by applanation tonometry. Biomicroscopy revealed profuse corneal edema and keratoconus and fluorescein staining was negative. Gonioscopy and ophthalmoscopy did not provide any relevant data due to the corneal alterations. Bullous keratopathy was diagnosed. Surgery was performed in two steps: 1 superficial keratectomy and 360º conjunctival flap, and 2 superficial keratectomy to restore corneal transparency. Thirty days after the second superficial keratectomy, the third eyelid flap was removed. Conjunctivalization of the upper nasal quadrant of the cornea was observed. The axial portion of the cornea was transparent and vision was restored.

    In order to compare the clinical characteristics of familial and non-familial bullous lichen planus (BLP), the archival data of 36 BLP patients with positive family history and 21 BLP patients with negative family history diagnosed according to the clinical features and histopathology were collected in our department from 1956 to 2003. The clinical features were analyzed and compared. There were significant differences between familial and non-familial BLP in age of onset, duration of disease and extension of eruption (P<0.01). It was concluded that familial BLP appeared to differ from the non-familial form in its earlier age of onset, longer duration of the disease, more extensive eruption and more tendency to involve nails. Hereditary factors may play a role in the pathogenesis of familial BLP.

    Rosacea is a very common skin disorder in the clinical practice that primarily affects the convex areas of the face. Extrafacial rosacea lesions have occasionally been described, but extensive involvement is exceptional. In the absence of its typical clinical or histological features, the diagnosis of extrafacial rosacea may be problematic. We describe an unusual case of rosacea with very exuberant extrafacial lesions, when compared with the limited involvement of the face.

    Full Text Available Context: Bullous pemphigoid (BP, the most common autoimmune blistering disease, is mediated by autoantibodies. BP primarily affects the elderly and is characterized by the development of urticarial plaques surmounted by subepidermal blisters, and the deposition of immunoglobulins and complement at the basement membrane zone (BMZ of the skin. BP is immunologically characterized by the development of autoantibodies targeting two structural proteins of the hemidesmosomes, BP180 (collagen XVII and BP230 (BPAG1.

Results: H&E demonstrated a subepidermal blister, with partial re-epithelialization of the blister floor. Within the blister lumen, numerous neutrophils were present, with occasional eosinophils and lymphocytes also noted. Within the dermis, a mild, superficial, perivascular and periadnexal infiltrate of lymphocytes, histiocytes and occasional eosinophils was identified, with mild perivascular leukocytoclastic debris. The PAS stain was positive at the BMZ, and around selected blood vessels, nerves and sweat glands. DIF revealed linear deposits of IgG and Complement/C3 and fibrinogen at the BMZ, and around selected dermal nerves, blood vessels and sweat glands. Strong granular deposits of IgE were also observed, colocalizing with monoclonal antibodies to Collagen IV (CIV. By IHC, positive CD45 staining of lymphocytes was seen surrounding selected dermal blood vessels, eccrine sweat glands, and nerves. Conclusion : The patient displayed IgG, IgE, and fibrinogen autoantibodies against the BMZ, as well as around some dermal nerves and sweat glands; their binding in the skin could trigger complement activation. In addition, the

    Full Text Available Introduction Presuming that psoriasis is an autoimmune skin disease, the aim of this study was to establish its association with other autoimmune skin diseases. The material was obtained at the Dermatovenereological Clinic Clinical Center Novi Sad. Material and methods This 10-year retrospective study (1990-1999 included 1743 psoriasis patients. The control group consisted of 7492 nonpsoriatic dermatological patients. Results Association of psoriasis with other dermatological diseases of autoimmune nature has been established in 13 (0.74 % patients. The most frequent association was with lichen ruber planus in five patients, with alopecia areata and vitiligo in three patients, and in one with bullous pemphigoid and herpetiform dermatitis. Using Fisher's test no significant association was established. Discussion and conclusion According to literature data association of psoriasis with other autoimmune diseases is well known, but rare, which is in accordance with our results. The question arises whether this association is the matter of poor coexistence or the matter of genetic mutations. However, once established, these associations can further highlight the autoimmune nature of psoriasis. The research of autoimmunity would lead us to epithelial cells in thymus, and their badly learnt cognitive function about what is own, and what is not.

    Full Text Available Long-term therapy with the macrolide antibiotic erythromycin was shown to alter the clinical course of diffuse panbronchiolitis in the late 1980s. Since that time, macrolides have been found to have a large number of anti-inflammatory properties in addition to being antimicrobials. These observations provided the rationale for many studies performed to assess the usefulness of macrolides in other inflammatory diseases including skin and hair disorders, such as rosacea, psoriasis, pityriasis rosea, alopecia areata, bullous pemphigoid, and pityriasis lichenoides. This paper summarizes a collection of clinical studies and case reports dealing with the potential benefits of macrolides antibiotics in the treatment of selected dermatoses which have primarily been classified as noninfectious and demonstrating their potential for being disease-modifying agents.

    Full Text Available Enterovirus A71 (EV-A71 causes self-limiting, hand-foot-and-mouth disease (HFMD that may rarely be complicated by encephalomyelitis. Person-to-person transmission is usually by fecal-oral or oral-oral routes. To study viral replication sites in the oral cavity and other tissues, and to gain further insights into virus shedding and neuropathogenesis, we developed a consistent, orally-infected, 2-week-old hamster model of HFMD and EV-A71 encephalomyelitis. Tissues from orally-infected, 2-week-old hamsters were studied by light microscopy, immunohistochemistry and in situ hybridization to detect viral antigens and RNA, respectively, and by virus titration. Hamsters developed the disease and died after 4-8 days post infection; LD50 was 25 CCID50. Macroscopic cutaneous lesions around the oral cavity and paws were observed. Squamous epithelium in the lip, oral cavity, paw, skin, and esophagus, showed multiple small inflammatory foci around squamous cells that demonstrated viral antigens/RNA. Neurons (brainstem, spinal cord, sensory ganglia, acinar cells (salivary gland, lacrimal gland, lymphoid cells (lymph node, spleen, and muscle fibres (skeletal, cardiac and smooth muscles, liver and gastric epithelium also showed varying amounts of viral antigens/RNA. Intestinal epithelium, Peyer's patches, thymus, pancreas, lung and kidney were negative. Virus was isolated from oral washes, feces, brain, spinal cord, skeletal muscle, serum, and other tissues. Our animal model should be useful to study squamous epitheliotropism, neuropathogenesis, oral/fecal shedding in EV-A71 infection, person-to-person transmission, and to test anti-viral drugs and vaccines.

    Skin tears are an increasingly common problem in frail elders, and the wound, ostomy, and continence (WOC) nurse must be knowledgeable regarding both prevention and management of these lesions. A literature review was conducted to identify current concepts regarding management of skin tears. Articles reviewed provided numerous suggested interventions and protocols. Recurring themes were prevention of skin tears whenever possible and management of existing lesions with products that manage the exudate, maintain a moist surface, and prevent additional trauma.

    2012-09-01

    In this report, we describe an 88-year-old male stroke patient with unilateral bullous pemphigoid limited to the hemiplegic side. Physical examinations revealed multiple tense bullae with clear and/or bloody contents without apparent erythema on the right thigh and lower leg, accompanied by erosions on the right chest. Histopathologically, no eosinophils were infiltrated into and around the subepidermal bullae. Immunofluorescence revealed deposited and circulating immunoglobulin (Ig)G anti-basement membrane zone antibodies. Immunoblot assays using various antigen sources and enzyme-linked immunosorbent assay revealed that IgG antibodies in this case reacted with unique epitopes between NC16a and C-terminal domains on the 120-kDa LAD-1, the extracellular truncated form of BP180. Three observations were unique in our case. First, the distribution of bullae in our patient was limited to the hemiplegic side. Second, there was no apparent erythema clinically and no eosinophilic infiltration histopathologically. Third, the patient achieved remission without the use of oral corticosteroids. The unusual epitopes in this case may contribute to these phenomena.

    Full Text Available Aim: To review the problem of the name of the agent, and to report epidemiologic features of 128 cases of nail and skin lesions caused by S.dimidiatum. Design: Descriptive study, partly retrospective (1990-1996 and partly prospective (1997-1999. Reference frame: Until recently there were problems with the nomenclature of the agent but now there exist arguments for solving the difficulties, and that was the first objective of our work: to present such arguments and to indicate the correct use of the different names. On the other hand, the importance of S. dimidiatum as agent of human lesions is increasing. This report is restricted to nail and skin lesions, of which we found 128 cases between 1990 and 1999. Methods: Laboratory records were reviewed and doubts were solved by means of consensus criteria. Mycological diagnostic criteria were established. Statistical analysis was performed with the Epi Info program, version 6.04; it consisted mainly of evaluating the association of variables with chi2 and in comparing positions of continuous and organized data according to their magnitude by means of the Kruskal-Wallis H test. Results: The different names of the agent should be used in precise situations, that are described. A total of 128 specimens was studied from which S. dimidiatum had been isolated in culture: 102 were from nails (92% from the feet and 26 from the skin (73% interdigital from feet. Epidemiologic features of a typical case of nail lesion due to S. dimidiatum indicate that in 41% the patients was an woman, 21-49 year-old, who uses “risk” shoes, presents hyperhydrosis and practices a sport. On the other hand typical epidemiologic features of a skin lesion due to S. dimidiatum are similar to these the only difference being the predominance of males (69%. Direct examination was positive in 97% of the cases and the most frequently found structures were threadlike hyphae charateristic of dermatophytes (72%, followed by sinous fungal

    2004-10-01

    Skin cancer due to occupation is more common than is generally recognized, although it is difficult to obtain an accurate estimate of its prevalence. Over the past two centuries, occupational skin cancers have particularly been due to industrial exposure of men (it seems more so than women) to chemical carcinogens such as polycyclic hydrocarbons (e.g. from coal tar products) or to arsenic. Industrial processes have improved in most Western countries to limit this type of exposure, but those with outdoor occupations are still exposed to solar ultraviolet irradiation without this being widely recognized as an industrial hazard. Ionizing radiation such as X-rays can also cause skin cancer. Occupational skin cancers often resemble skin tumours found in non-occupational subjects, e.g. basal cell carcinoma, squamous cell carcinoma and malignant melanoma, but some pre-malignant lesions can be more specific and point to an occupational origin, e.g. tar keratoses or arsenical keratoses. An uncommon but well-recognized cause of occupational skin cancer is that which results from scar formation following an industrial burn. In the future it will be necessary to focus on preventative measures, e.g. for outdoor workers, the need to cover up in the sun and use sun protective creams and a campaign for earlier recognition of skin cancers, which are usually curable if treated in their early stages.

    2016-05-01

    The cutaneous microbiome has been investigated broadly in recent years and some traditional perspectives are beginning to change. A diverse microbiome exists on human skin and has a potential to influence pathogenic microbes and modulate the course of skin disorders, e.g. atopic dermatitis. In addition to the known dysfunctions in barrier function of the skin and immunologic disturbances, evidence is rising that frequent skin disorders, e.g. atopic dermatitis, might be connected to a dysbiosis of the microbial community and changes in the skin microbiome. As a future perspective, examining the skin microbiome could be seen as a potential new diagnostic and therapeutic target in inflammatory skin disorders.

    Full Text Available Mycetoma is a chronic, granulomatous disease of the skin, and subcutaneous tissue, which sometimes involves muscle, bones, and neighboring organs. It is characterized by tumefaction, abscess formation, and fistulae with discharge of grains from sinuses. Mycetoma can be caused by various species of fungi (eumycetoma and aerobic actinomycetes (actinomycetoma, which occur as saprophytes in soil or plants. A tentative diagnosis sufficient to initiate treatment may be made on the basis of grain color. For instance, melanoid grains are always caused by fungi and ochroid or pale grains by actinomycetes. Although this is not the thumbrule, there are exceptional reports too. As trauma favors infection, most lesions are on the foot and lower leg but they may occur anywhere on the body mimicking actinomycosis. However, lab investigations and culture are important tool to differentiate apart from the clinical picture. We are reporting atypical case with unusual site of presentation (perineum and thigh of mycetoma.

    2016-01-01

    Morgellons disease is characterized by complaints of uncomfortable skin sensations and fibers emanating from nonhealing skin lesions. Morgellons disease is well-known in the dermatology and psychiatry literature, where it is typically considered a subtype of delusional parasitosis, but it has not yet been described in the ophthalmology literature. A patient with self-reported Morgellons disease is presented, who was referred for evaluation of left lower eyelid ectropion. She reported that her skin was infested with fibers that were "trying to get down into the eyelid." On examination, she had ectropion of the left lower eyelid, broken cilia, and an ulcerated left upper eyelid lesion concerning for carcinoma. Biopsy of the lesion was consistent with excoriation. Treatment of her ectropion was deferred out of concern for wound dehiscence, given the patient's aggressive excoriation behavior. This case is presented to make the ophthalmologist aware of this disorder and to highlight the appropriate clinical management. PMID:25192328

    Atypical fibroxanthoma (AFX) is a spindle cell neoplasm with low metastatic potential but high tendency to recur after surgery. Because of the rarity of this lesion and its aspecific clinical features, AFX could be easily misdiagnosed and undertreated by many clinicians who encounter them. Dermoscopy represents a valuable tool for easily assessing skin lesions, even though histological examination is required for final diagnosis. We report a case of a cheek lesion with dermoscopic “blue amber pattern”, easily recognisable and not observed in others skin tumours, which could represent an additional feature useful in differentiating this tumour from other skin neoplasms.

    The bacteriologic, epidemiologic, clinical, and diagnostic findings and management of the scalded skin syndrome (SSS) in 42 children are reported SSS may present in one of three ways: (1) Ritter's disease in infants, characterized by an acute, generalized bullous dermatitis simulating the appearance of scalded skin, followed by exfoliation; (2) Lyell's disease, or toxic epidermal necrolysis (TEN), in children or adults, with scalded skin and bullae followed by extensive exfoliation; or (3) a nonstreptococcal scarlatiniform eruption, or staphylococcal scarlet fever, manifested by a generalized scarlatiniform erythema ans subsequent minimal to moderate fine desquamation. Staphylococcus aureus was isolated and implicated as the causative agent in 32 of the 42 children; nine of the other ten children had received a drug or vaccine preceding their rash. SSS in children has increased in frequency recently, is usually due to S aureus infection with potential epidemic aspects, can be recognized easily by its unusual clinical features, and has an excellent prognosis with appropriate management.

  8. Skin: Major target organ of allergic reactions to small molecular weight compounds

    International Nuclear Information System (INIS)

    Skin is a major target organ for allergic reactions to small molecular weight compounds. Drug allergic reactions may be life-threatening such as in the case of anaphylactic reactions or bullous drug reactions and occur in about 5% of all hospitalized patients. Allergic contact dermatitis has an enormous influence on the social life of the patient because it is the most frequent reason for occupational skin diseases and the treatment and prevention of this disease cost approximately Euro 3 billion per year in Germany. The different proposed pathophysiological pathways leading to a drug eruption are discussed in this paper. All major enzymes which are involved in the metabolism of xenobiotica were shown to be present in skin. Evidence supporting the role of metabolism in the development of drug allergy and allergic contact dermatitis is demonstrated in the example of sulphonamides and fragrances

    T.J.'s case was interesting from the standpoint of both diagnosis and management. The recommended treatment for this drug reaction was prednisone: however, the use of a steroid in a patient who is neutropenic and has a fever is risky because the because the steroid can mask the symptoms of infection (e.g., fever). Administration of prednisone did help, and the patient experienced a rapid resolution of the skin rash. T.J. will need to avoid the use of these antibiotic agents in the future. Because it is unknown which antibiotic, vancomycin or ceftazidime, caused the allergic reaction, both medicines should be avoided. The decision to rechallenge a patient with a specific drug must be made on an individual basis. Rechallenging of a drug in patients who have had urticarial, bullous, or erythema multiforme-like eruptions can be very dangerous (Padial et al., 2000). Pinpointing the cause of a skin rash can be puzzling. Always ask the patient "Do you take any medicine for any condition (including aspirin, laxatives, vitamins, etc.)? Have you received any shots any shots in the last month?" Keep in mind that any chemical that is ingested can cause a cutaneous drug eruption. PMID:11899630

    2014-01-01

    Twenty-eight goldring surgeonfish, Ctenochaetus strigosus (Bennett), manifesting skin lesions and originating from the north-western and main Hawaiian Islands were examined. Skin lesions were amorphous and ranged from simple dark or light discolouration to multicoloured tan to white sessile masses with an undulant surface. Skin lesions covered 2–66% of the fish surface, and there was no predilection for lesions affecting a particular part of the fish. Males appeared over-represented. Microscopy revealed the skin lesions to be hyperplasia, melanophoromas or iridophoromas. The presence of skin tumours in a relatively unspoiled area of Hawaii is intriguing. Explaining their distribution, cause and impact on survivorship of fish all merit further study because C. strigosus is an economically important fish in the region.

  15. Collagen IV in normal skin and in pathological processes

    Directory of Open Access Journals (Sweden)

    Ana Maria Abreu-Velez

    2012-01-01

    Full Text Available Context: Type IV collagen is a type of collagen found primarily in the skin within the basement membrane zone. The type IV collagen C4 domain at the C-terminus is not removed in post-translational processing, and the fibers are thus link head-to-head, rather than in a parallel fashion. Also, type IV collagen lacks a glycine in every third amino-acid residue necessary for the tight collagen helix. Thus, the overall collagen-IV conformation is structurally more pliable and kinked, relative to other collagen subtypes. These structural features allow collagen IV to form sheets, which is the primary structural form found in the cutaneous basal lamina. There are six human genes associated with collagen IV, specifically COL4A1, COL4A2, COL4A3, COL4A4, COL4A5 and COL4A6. The aim of this review is to highlight the significance of this protein in normal skin, and in selected diseases. Results: The alpha 3 protein constituent of type IV collagen is thought to be the antigen implicated in Goodpasture′s syndrome, wherein the immune system attacks the basement membranes of the renal glomeruli and pulmonary alveoli. In addition, mutations to the genes coding for type IV collagen lead to the Alport syndrome. Furthermore, autoantibodies directed against denatured human type IV collagen have been described in rheumatoid arthritis, scleroderma, and SLE. Structural studies of collagen IV have been utilized to differentiate between subepidermal blistering diseases, including bullous pemphigoid, acquired epidermolysis bullosa, anti-epiligrin cicatricial pemphigoid, and bullous lupus erythematosus. Collagen IV is also of importance in wound healing and in embryogenesis. Conclusions: Pathological studies have demonstrated that minor structural differences in collagen IV can lead to distinct, clinically different diseases.

    This study evaluated whether the specific heavy pig rearing context allowed the fattening of undocked pigs without an outbreak of tail biting. At the same time, gender and straw availability (small amounts) were considered to understand their possible interactions with tail presence in the display of tail biting. A 2 × 2 × 2 factorial design was adopted to test the effects of these factors on blood parameters, behaviour and tail/ear lesions. Few interactions among factors were detected. Undocked pigs showed lower cortisol (Ptail/ear biting (weeks 3 and 9), but lower risk of tail lesions (week 14). Straw increased the motivation for exploring (Ptail biting (weeks 3, 9, 18) and ear biting (weeks 3, 9). Results highlight the importance of straw as an environmental enrichment and seem to indicate that fattening undocked heavy pigs is possible. PMID:23876332

    Full Text Available Vulval symptoms are commonly found and cause considerable distress for women. Symptoms are often chronic and can significantly affect the quality of womens lives including sexual function and wellbeing. Despite the frequency of vulval symptoms, women often find it difficult to seek medical advice due to multiple reasons, mostly cultural and emotional. This part is not easily self-observable neither are women aware of the fact that a vulvar lesion could also be a manifestation of a systemic disease. The idea behind this study was to identify whether presenting vulval lesion is dermatological or non-dermatological and to control the symptoms, to identify nature of the various vulvar lesions (inflammatory or neoplastic and to identify those skin lesions not responding to treatment which require biopsy and further management. It was a clinical descriptive study. Cases included women with vulvar lesions who attended Gynaec OPD at Dhiraj General Hospital affiliated to S.B.K.S. Medical Institute and Research Centre of Vadodara. After taking their informed consent ,all the women who had symptoms like vaginal discharge, itching or discomfort associated a with vulvar lesion, visible lesion or growth over vulva were thoroughly investigated to rule out any systemic illness causing vulvar lesion following which biopsy was taken if solid growth or a non-healing lesion was present. Treatment was done according to the lesions. In the presence of vulvar complains, a diagnostic pathway including systematic physical examination is always mandatory to detect SCC early. A non-healing lesion must be subjected to biopsy mandatorily. Women should be educated to avoid ODC drugs or creams when they face vulval lesions.

    Full Text Available ABSTRACT Objective: For nearly a century, penetrating keratoplasty has been the surgical technique of choice in the management of corneal changes. However, in recent years, several lamellar keratoplasty techniques have been developed, modified or improved, especially techniques for replacing the posterior portion, for the correction of bullous keratopathy. The aim of this study was to evaluate the effectiveness and safety of endothelial keratoplasty versus penetrating keratoplasty for pseudophakic and aphakic bullous keratopathy. Methods: A systematic review of the literature was carried out, and the main electronic databases were searched. The date of the most recent search was from the inception of the electronic databases to December 11, 2015. Two authors independently selected relevant clinical trials, assessed their methodological quality and extracted data. Results: The electronic search yielded a total of 893 published papers from the electronic databases. Forty-four full-text articles were retrieved for further consideration. Of these 44 full-text articles, 33 were excluded because they were all case series studies; therefore, ten studies (with one further publication met the inclusion criteria: one randomized clinical trial with two publications; three controlled studies; and six cohort studies. The clinical and methodological diversity found in the included studies meant that it was not possible to combine studies in a metaanalysis. Conclusions: There is no robust evidence that endothelial keratoplasty is more effective and safe than penetrating keratoplasty for improving visual acuity and decreasing corneal rejection for pseudophakic and aphakic bullous keratopathy. There is a need for further randomized controlled trials.

    Full Text Available Background/Aim: Glycyrrhizin (GL is an important derivative of certain herbal medicines used in Asian countries. Currently, GL is used to treat hepatitis and allergic disease worldwide because of its anti-viral and anti-allergy effects. In addition to these prominent functions, GL likely regulates cellular functions such as tumor cell growth and cellular immunity. However, how GL affects the keratinocyte inflammation response remains poorly understood. The current paper investigates the effect of GL on psoriasis and explores the mechanisms involved. Methods: We used an in vitro cell model of tumor necrosis factor (TNF-a-induced keratinocyte inflammation and the topical application of imiquimod (IMQ using an animal model (mouse skin of IMQ-induced psoriasis-like inflammation (IPI to investigate the effect of GL on skin inflammation. Cell viability was analyzed using the Cell Counting Kit-8 (CCK8. Carboxyfluorescein succinimidyl ester (CFSE labeling was used to trace monocyte adherence to keratinocytes. A Western blot analysis was used to detect the expression of intercellular adhesion molecule 1 (ICAM-1 and the activation of the nuclear factor (NF-κB/mitogen-activated protein kinase (MAPK signaling pathway. A modified version of the Psoriasis Area Severity Index (PASI was used to monitor disease severity. Hematoxylin and eosin (H&E staining was used to observe pathological changes. An immunohistochemistry (IHC analysis was used to detect ICAM-1 expression in mouse skin. Results: GL treatment significantly reduced the levels of ICAM-1 in TNF-a-stimulated HaCaT cells, inhibited subsequent monocyte adhesion to keratinocytes, and suppressed the nuclear translation and phosphorylation of p65 following the degradation of inhibitor κB (IκB. GL treatment blocked the phosphorylation of extracellular signal-regulated kinase (ERK/p38 MAPK. GL effectively delayed the onset of IPI in mice and ameliorated ongoing IPI, thereby reducing ICAM-1 expression in

  9. Staphylococcal scalded skin syndrome: diagnosis and management.

    2003-01-01

    Staphylococcal scalded skin syndrome (SSSS) is a common disorder that is usually seen in infants and children and rarely seen in adults. SSSS usually presents with a prodrome of sore throat or conjunctivitis. Extremely tender flaccid bullae, which are Nikolsky sign-positive, develop within 48 hours and commonly affect the flexures; occasionally, large areas of the skin may be involved. The bullae enlarge and rupture easily to reveal a moist erythematous base, which gives rise to the scalded appearance. SSSS in adults is a rare disorder, though there are now over 50 documented cases. Usually SSSS occurs in predisposed individuals, but not all adults have an underlying illness. Whereas mortality in childhood SSSS is approximately 4%, the mortality rate in adults is reported to be greater than 60%. SSSS is caused by an infection with a particular strain of Staphylococcus aureus, which leads to blistering of the upper layer of the skin, by the release of a circulating exotoxin. It has recently been demonstrated that the exfoliative exotoxin responsible for SSSS leads to the cleavage of desmoglein 1 complex, an important desmosomal protein. The same toxins that are responsible for causing SSSS also cause bullous impetigo. There appears to be a relationship between the disease extent, the amount of toxin produced and whether the toxin is released locally or systemically. As a result there is likely to be a spectrum of disease and there are likely to be a number of milder cases of adult SSSS that go undiagnosed. Social improvements and hygiene have led to a dramatic fall in the number of cases of SSSS. Treatment is usually straightforward, when there is no coexistent morbidity and the presentation is mild, but can be demanding if the patient is particularly ill. SSSS is still associated with mortality, particularly when it occurs in adults. PMID:12627992

    Fivenson, David P

    2006-01-01

    Nicotinamide (niacinamide), a physiologically active form of niacin (nicotinic acid), in combination with zinc is being assessed in clinical studies for the treatment of inflammatory skin diseases such as acne vulgaris and bullous pemphigoid. The basis for these investigations is the variety of potential mechanisms of action of nicotinamide and zinc, including an anti-inflammatory effect via inhibition of leukocyte chemotaxis, lysosomal enzyme release, lymphocytic transformation, mast cell degranulation, bacteriostatic effect against Propionibacterium acnes, inhibition of vasoactive amines, preservation of intracellular coenzyme homeostasis, and decreased sebum production. Other possible mechanisms involve suppression of vascular permeability and inflammatory cell accumulation, as well as protection against DNA damage. The goal of this paper is to review the pathophysiology of inflammatory skin diseases and discuss the role, mechanisms of action, and safety of nicotinamide and zinc as therapeutic options for these disorders.

    Warfarin skin necrosis (WSN) is an infrequent complication of warfarin treatment and is characterized by painful ulcerative skin lesions that appear a few days after the start of warfarin treatment. Calciphylaxis also appears as painful skin lesions caused by tissue injury resulting from localized ischemia caused by calcification of small- to medium-sized vessels in patients with end-stage renal disease. We report on a patient who presented with painful skin ulcers on the lower extremities after the administration of warfarin after a valve operation. Calciphylaxis was considered first because of the host factors; eventually, the skin lesions were diagnosed as WSN by biopsy. The skin lesions improved after warfarin discontinuation and short-term steroid therapy. Most patients with end-stage renal disease have some form of cardiovascular disease and some require temporary or continual warfarin treatment. It is important to differentiate between WSN and calciphylaxis in patients with painful skin lesions. PMID:27069859

    Background: Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, automated analysis of dermoscopy images has become an important research area. Border detection is often the first step in this analysis. Methods: In this article, we present an approximate lesion localization method that serves as a preprocessing step for detecting borders in dermoscopy images. In this method, first the black frame around the image is removed using an iterative algorithm. The approximate location of the lesion is then determined using an ensemble of thresholding algorithms. Results: The method is tested on a set of 428 dermoscopy images. The localization error is quantified by a metric that uses dermatologist determined borders as the ground truth. Conclusion: The results demonstrate that the method presented here achieves both fast and accurate localization of lesions in dermoscopy images.

    2016-03-01

    Perianal skin lesions, such as skin tags, can be an early presenting sign of Crohn's disease. Surgical intervention on these lesions may increase the risk of fistula development and lead to worse outcomes. This case series examined 8 patients who underwent surgical intervention on what appeared to be benign perianal skin lesions, only to reveal fistulas leading to the diagnosis of Crohn's disease. This patient population comprised 20% of all pediatric patients with Crohn's disease who had perianal fistula present at diagnosis. The initial type of perianal lesion varied from case to case and included skin tags, hemorrhoids, and perianal abscesses. All of the patients had other presenting features that, in retrospect, may have been attributed to Crohn's disease. None presented solely with a perianal lesion. Four patients had weight loss or growth failure. Most of the remainder had abnormal laboratory test results. These findings should raise the awareness of primary care providers that perianal lesions can be the first presenting sign of possible Crohn's disease in otherwise healthy appearing children. Such children should undergo a thorough evaluation for Crohn's disease before surgical intervention on perianal lesions because surgical procedures may be associated with worse outcomes.

    2008-01-01

    In order to investigate the role of MMP-9 and TIMP-1 in the pathogenesis of systemic sclerosis, the expression of MMP-9 and TIMP-1 was immunohistochemically detected in skin lesions of the patients with diffuse cutaneous systemic sclerosis, skin lesions of the patients with limited cutaneous systemic sclerosis, and skin tissues of normal subjects. The results showed that the expression of MMP-9 in lesions of diffuse cutaneous systemic sclerosis was significantly lower than that of normal skins (P<0.05). However, no significant difference in the level of MMP-9 in the limited cutaneous systemic sclerosis and normal skin was found. Meanwhile, the expression of TIMP-1 in lesions of diffuse cutaneous systemic sclerosis and limited cutaneous systemic sclerosis were significantly higher than that of normal skins (both P<0.05). It was suggested that the expression of MMP-9 and TIMP-1 might play an important role in the development of systemic sclerosis.

    Full Text Available Aim: To evaluate the number of lesions of psoriasis and to find risk factors for multiple lesions. Material and Methods: 1,236 patients (male 54.13%, female 45.87% with psoriasis were seen over a period of 8 years in an Outpatient Clinic. Patients filled out questionnaires containing age at onset, number of lesions and location at the beginning of the disease, gender, type and localization of psoriasis at the time of clinical examination, psoriasis family history, previous treatment, comorbidities, and social status. Results: The number of psoriasis lesions correlates with: onset age of psoriasis (F=8.902, p=0.0029; age at the moment of clinical examination (F=8.902, p=0.0029; residence in rural area (χ2=8.589, p=0.00338, 95%CI; alcohol intake (χ2=16.47, p=0.00005, 95%CI; smoking (χ2=8.408, p=0.00373, 95%CI; occupation: workers/pupils/students (χ2=14.11, p=0.0069, 95%CI. Conclusions: There is a correlation between number of psoriatic lesions and some factors. Multiple lesions were observed in older patients, smokers and drinkers, coming from rural area and social active (workers and pupils/students. No correlation was statistically proved between number of lesions and gender, comorbidities and family history of psoriasis.

  8. Skin microbiome and skin disease: the example of rosacea.

    Picardo, Mauro; Ottaviani, Monica

    2014-01-01

    The imbalance and/or the perturbation of the microbial populations that colonize the skin and that contribute to its defense may represent one of the causes of the development of noninfectious skin diseases. Atopic dermatitis, psoriasis, acne, and rosacea can be listed among these kinds of pathologies. In particular, considering that microbes have been long addressed as having a role in rosacea, this common dermatosis can be an interesting model to evaluate the correlation between microbiome alterations and the occurrence of clinical manifestations. Different microorganisms have been suggested to have a role in rosacea, but no direct correlation with the incidence of the pathology has been clearly defined. Skin microbiome composition is crucial for the correct skin immune functions and recent findings indicate an abnormal activation of innate immune system associated with the rosacea. The enhanced expression of toll-like receptor 2 in the epidermis of rosacea patients can represent a possible explanation for the amplified inflammatory response to external stimuli observed during the disease. In addition, significantly higher small intestinal bacterial overgrowth prevalence in rosacea subjects has been found and its eradication has been associated with a regression of the skin lesions. In conclusion, both skin and gut microbiome seem to have a role, even if synergistic with other factors, in the pathogenesis of rosacea. A deeper knowledge of human microbiome composition and microbe-host interactions will contribute to clarify the mechanism of development of rosacea and possibly will provide innovative therapeutic approaches.

  10. Periodontal bone lesions

    International Nuclear Information System (INIS)

    In the course of life the periodontum is subject to changes which may be physiological or pathological. Intraoral radiographs give insight into the hard structures of the dentomaxillar region and provides information on lesions in the bone of the periodontum in that they show radiopacities and radiolucencies caused by such lesions. In this thesis the relation is investigated between the true shape and dimensions of periodontal bone lesions and their radiographic images. A method is developed and tested of making standardized and reproducible radiographs suitable for longitudinal studies of periodontal lesions. Also the possibility is demonstrated of an objective and reproducible interpretation of radiographic characteristics of periodontal bone lesions. (Auth.)

    Persistent air leakage is a serious and sometimes fatal complication of bullous lung disease surgery. A 32-year-old man with lung involvement of neurofibromatosis type I underwent bullectomy for huge bullae and recurrent pneumothorax. Persistent postoperative air leakage developed and the lung was totally collapsed. The initial surgery failed, but a second trial employing a novel suture technique on half-absorbed polyglycolic acid (PGA) felt successfully resolved the massive air leakage. Pneumothorax did not recur and the patient remained stable without dyspnea. Thus, a suture technique employing half-absorbed PGA felt was an effective option for managing persistent air leakage.

    To investigate the role of toll-like receptor 9 (TLR9) in the pathogenesis of lichen planus,the expressions of TLR9 and its mRNA in the lesional skin of lichen planus were detected by immunohistochemical technique (SP) and RT-PCR. As control, normal skin of healthy volunteers was also tested. The immunohistochemical study showed that the expression of TLR9 in the lesional skin of lichen planus was significantly higher than that in the normal controls. The results of RT-PCR showed that both skin lesions and normal controls had TLR9 expression. In skin lesions, the expression level of TLR9 mRNA was 1.6075±0.0930, which was significantly higher than that in normal controls (P<0.001). These findings indicated that up-regulated expression of TLR9 and its mRNA might be involved in the pathogenesis of lichen planus.

    In human vitiligo, cutaneous depigmentation involves cytotoxic activity of autoreactive T cells. It was hypothesized that depigmentation can progress in the absence of regulatory T cells (Treg). The percentage of Treg among skin infiltrating T cells was evaluated by immunoenzymatic double staining for CD3 and FoxP3, revealing drastically reduced numbers of Treg in non-lesional, perilesional and lesional vitiligo skin. Assessment of the circulating Treg pool by FACS analysis of CD4, CD25, CD12...

    Nuclear medicine provides several methods for increasing the accuracy of surgical removal of bone lesions with focally increased uptake. In this paper, three intraoperative procedures are discussed: remote control by imaging, intraoperative control by imaging, and intraoperative control by scintillation probe. All techniques require preoperative injection of bone imaging tracer. Remote operative control calls for a gamma camera to mark the skin over the lesion prior to surgery, providing optimal preoperative localization and imaging of the excised lesion to ensure complete removal. Intraoperative control procedures require that a portable camera or a scintillation probe be used in the operating room; these permit direct monitoring of localization and resection. Our experience with 18 procedures performed on 15 patients suggests that these techniques are worthy of continued use.

    This chapter focusses on the probability of a caries lesion detected during a clinical examination being active (progressing) or arrested. Visual and tactile methods to assess primary coronal lesions and primary root lesions are considered. The evidence level is rated as low (R(w)), as there are...... response to cariogenic plaque as well as lesion arrest. Based on this understanding, different clinical scoring systems have been developed to assess the severity/depth and activity of lesions. A recent system has been devised by the International Caries Detection and Assessment System Committee. The...... literature suggests that there is a fair agreement between visual/tactile external scripts of caries and the severity/depth of the lesion. The reproducibility of the different systems is, in general, substantial. No single clinical predictor is able to reliably assess activity. However, a combination of...

    Full Text Available Background: Autoimmune vesiculobullous disorders represent a heterogeneous group of dermatoses whose diagnosis is made based on clinical history, histologic features, and immunopathologic features. The most commonly used techniques for the diagnosis of these diseases are direct and indirect immunofluorescence (DIF and IIF, including salt-split processing. NaCl split skin is used to determine the level of blister formation, and the localization of autoantibodies relative to the split. Classically, immunofluorescence has been performed with one fluorochrome in the diagnosis of autoimmune bullous skin diseases. Aims: To compare DIF and IIF of the skin, using a single fluorochrome versus multiple fluorochromes. Materials and Methods: We studied 20 autoimmune skin disease cases using fluorescein isothiocyanate (FITC alone, in comparison to multiple fluorochromes (with or without DNA counterstaining. Results: The use of multiple fluorochromes helped to simultaneously visualize reactivity in multiple skin areas, in contrast to using FITC alone. Conclusions: Using multiple fluorochromes allows simultaneous labeling of two or more antigens within the same cell/or tissue section, assists in colocalization of unknown antigens with known molecules, and helps in ruling out "background" staining.

    For the first time, high frequency ultrasound imaging, multiphoton tomography, and dermoscopy were combined in a clinical study. Different dermatoses such as benign and malign skin cancers, connective tissue diseases, inflammatory skin diseases and autoimmune bullous skin diseases have been investigated with (i) state-of-the-art and highly sophisticated ultrasound systems for dermatology, (ii) the femtosecond-laser multiphoton tomograph DermaInspectTM and (iii) dermoscopes. Dermoscopy provides two-dimensional color imaging of the skin surface with a magnification up to 70x. Ultrasound images are generated from reflections of the emitted ultrasound signal, based on inhomogeneities of the tissue. These echoes are converted to electrical signals. Depending on the ultrasound frequency the penetration depth varies from about 1 mm to 16 mm in dermatological application. The 100-MHz-ultrasound system provided an axial resolution down to 16 μm and a lateral resolution down to 32 μm. In contrast to the wide-field ultrasound images, multiphoton tomography provided horizontal optical sections of 0.36×0.36 mm2 down to 200 μm tissue depth with submicron resolution. The autofluorescence of mitochondrial coenzymes, melanin, and elastin as well as the secondharmonic- generation signal of the collagen network were imaged. The combination of ultrasound and multiphoton tomography provides a novel opportunity for diagnostics of skin disorders.
