    Bovine digital dermatitis (DD) is a severe infectious disease causing lameness in dairy cattle worldwide and is an important ruminant welfare problem that has considerable economic issues. Bovine DD is endemic in many regions worldwide and it is important to understand this major disease so that effective control strategies can be identified. There is substantial evidence that specific treponeme phylotypes play an important causative role in bovine DD. This review considers current research, including DD Treponema spp. investigations, associated DD pathobiology, and current and potential treatment and control options. Epidemiological data, alongside new microbiological data, help delineate important transmission routes and reservoirs of infection that allow effective interventions to be identified. Better on-farm housing hygiene, pasture access, routine footbathing and claw trimming with disinfected equipment need to be implemented to significantly reduce the incidence of DD. There is a paucity of peer reviewed research into both commonly used and novel treatments. In vitro antimicrobial susceptibility studies of DD treponemes and effective treatment of human treponematoses clearly indicate that antibiotics frequently selected for DD treatments are not the most efficacious. Whilst there are understandable concerns over milk withdrawal times in dairy cattle, more needs to be done to identify, license and implement more appropriate antibiotic treatments, since continued overuse of less efficacious antibiotics, applied incorrectly, will lead to increased disease recurrence and transmission. More research is needed into methods of preventing DD that circumvent the use of antibiotics, including vaccination and transmission blocking studies, to reduce or hopefully eradicate DD in the future.

    Full Text Available Metagenomic methods amplifying 16S ribosomal RNA genes have been used to describe the microbial diversity of healthy skin and lesion stages of bovine digital dermatitis (DD and to detect critical pathogens involved with disease pathogenesis. In this study, we characterized the microbiome and for the first time, the composition of functional genes of healthy skin (HS, active (ADD and inactive (IDD lesion stages using a whole-genome shotgun approach. Metagenomic sequences were annotated using MG-RAST pipeline. Six phyla were identified as the most abundant. Firmicutes and Actinobacteria were the predominant bacterial phyla in the microbiome of HS, while Spirochetes, Bacteroidetes and Proteobacteria were highly abundant in ADD and IDD. T. denticola-like, T. vincentii-like and T. phagedenis-like constituted the most abundant species in ADD and IDD. Recruitment plots comparing sequences from HS, ADD and IDD samples to the genomes of specific Treponema spp., supported the presence of T. denticola and T. vincentii in ADD and IDD. Comparison of the functional composition of HS to ADD and IDD identified a significant difference in genes associated with motility/chemotaxis and iron acquisition/metabolism. We also provide evidence that the microbiome of ADD and IDD compared to that of HS had significantly higher abundance of genes associated with resistance to copper and zinc, which are commonly used in footbaths to prevent and control DD. In conclusion, the results from this study provide new insights into the HS, ADD and IDD microbiomes, improve our understanding of the disease pathogenesis and generate unprecedented knowledge regarding the functional genetic composition of the digital dermatitis microbiome.

    Studies concerning bovine digital dermatitis showed a moderate to severe presence of eosinophils at histopathologic exams, but the cause still a speculation. The aim of this study was observe and quantify the eosinophilia in digital lesions in different stages of the disease. Forty female bovine were allocated in four groups with ten animals each, whereas the GI were healthy animals; GII, animals in initial stage of the disease: GIII, animals with erosive lesions; and GIV, animals with papillomatous lesions. The histologic exam showed local and diffuse eosinophilic infiltrated in the lesions, mainly in papillary dermis and the infiltrated was proportional to the lesion degree of the animals. 

    KEY WORDS: Cattle, digital disease, eosinophils, histopathology.
    Estudos demonstram que as lesões causadas pela dermatite digital bovina apresentam expressiva quantidade de eosinófilos, mas seus aspectos ainda são motivos de especulação. O presente estudo teve como objetivo quantificar a eosinofilia tecidual presente em lesões de dermatite digital, nas diferentes fases da doença. Foram utilizadas quarenta fêmeas bovinas distribuídas em quatro grupos compostos de dez animais, sendo que o grupo GI constituiu-se de animais saudáveis, GII de animais na fase inicial da doença, GIII de bovinos com lesões erosivas e o grupo GIV formado por animais portadores de lesões na forma papilomatosa. O exame histopatológico revelou infiltrado inflamatório eosinofílico nas diferentes lesões digitais examinadas, principalmente na derme papilar, apresentando distribuição que variou de difusa a focal e/ou multifocal. O aumento na intensidade deste infiltrado foi proporcional ao grau da lesão.

  7. Altered microbiomes in bovine digital dermatitis lesions, and the gut as a pathogen reservoir.

    Directory of Open Access Journals (Sweden)

    Martin Zinicola

    Full Text Available Bovine digital dermatitis (DD is the most important infectious disease associated with lameness in cattle worldwide. Since the disease was first described in 1974, a series of Treponema species concurrent with other microbes have been identified in DD lesions, suggesting a polymicrobial etiology. However, the pathogenesis of DD and the source of the causative microbes remain unclear. Here we characterized the microbiomes of healthy skin and skin lesions in dairy cows affected with different stages of DD and investigated the gut microbiome as a potential reservoir for microbes associated with this disease. Discriminant analysis revealed that the microbiomes of healthy skin, active DD lesions (ulcerative and chronic ulcerative and inactive DD lesions (healing and chronic proliferative are completely distinct. Treponema denticola, Treponema maltophilum, Treponema medium, Treponema putidum, Treponema phagedenis and Treponema paraluiscuniculi were all found to be present in greater relative abundance in active DD lesions when compared with healthy skin and inactive DD lesions, and these same Treponema species were nearly ubiquitously present in rumen and fecal microbiomes. The relative abundance of Candidatus Amoebophilus asiaticus, a bacterium not previously reported in DD lesions, was increased in both active and inactive lesions when compared with healthy skin. In conclusion, our data support the concept that DD is a polymicrobial disease, with active DD lesions having a markedly distinct microbiome dominated by T. denticola, T. maltophilum, T. medium, T. putidum, T. phagedenis and T. paraluiscuniculi. Furthermore, these Treponema species are nearly ubiquitously found in rumen and fecal microbiomes, suggesting that the gut is an important reservoir of microbes involved in DD pathogenesis. Additionally, the bacterium Candidatus Amoebophilus asiaticus was highly abundant in active and inactive DD lesions.

    Bovine digital dermatitis (DD) is an increasing claw health problem in all cattle production systems worldwide. The objective of this study was to evaluate the use of an improved scoring of the clinical status for DD via M-scores accounting for the dynamics of the disease; that is, the transitions from one stage to another. The newly defined traits were then subjected to a genetic analysis to determine the genetic background for susceptibility to DD. Data consisted of 6,444 clinical observations from 729 Holstein heifers in a commercial dairy herd, collected applying the M-score system. The M-score system is a classification scheme for stages of DD that allows a macroscopic scoring based on clinical inspections of the bovine foot, thus it describes the stages of lesion development. The M-scores were used to define new DD trait definitions with different complexities. Linear mixed models and logistic models were used to identify fixed environmental effects and to estimate variance components. In total, 68% of all observations showed no DD status, whereas 11% were scored as infectious for and affected by DD, and 21% of all observations exhibited an affected but noninfectious status. For all traits, the probability of occurrence and clinical status were associated with age at observation and period of observation. Risk of becoming infected increased with age, and month of observation significantly affected all traits. Identification of the optimal month concerning DD herd status was consistent for all trait definitions; the last month of the trial was identified. In contrast, months exhibiting the highest least squares means of transformed scores differed depending on trait definition. In this respect, traits that can distinguish between healthy, infectious, and noninfectious stages of DD can account for the infectious potential of the herd and can serve as an alert tool. Estimates of heritabilities of traits studied ranged between 0.19 (±0.11) and 0.52 (±0

    Pressure sores cause severe pain and discomfort in hospitalized people and in farmed cattle and are often infected with unknown bacteria. Pressure sores occur on the upper legs of 6-10% of recumbent cattle and are generally considered to be caused by constant pressure, commonly on bony areas of the limbs. This study analyzed pressure sores taken from the upper limbs of 14 cattle using isolation in culture and nested polymerase chain reaction (PCR) to detect treponemes associated with digital dermatitis (DD). A 100% association of DD treponemes with the pressure sores was demonstrated, but treponemes were shown not to be part of the normal skin microbiota. Immunohistochemistry showed an association of DD treponemes with lesions and particularly with the hair follicles in lesions, identifying the bacteria deep within wounds, thereby suggesting that they could contribute to lesion pathogenesis. The bacteria isolated from the pressure sore lesions were similar or identical on analysis of the 16S rRNA gene to those found in DD foot lesions in cattle, suggesting the same bacteria can infect multiple lesions. Indeed, the results of this study suggest that these spirochaetal bacteria may be expanding in host range and in their ability to colonize different tissues and contribute to a range of disease manifestations in farm animals.

    Full Text Available Jennifer H Wilson-Welder, David P Alt, Jarlath E Nally Bacterial Diseases of Livestock Research Unit, National Animal Disease Center, Agricultural Research Service, United States Department of Agriculture, Ames, IA, USA Abstract: Digital dermatitis (DD is a multifactorial polymicrobial infectious disease originally described in dairy cattle, but is increasingly recognized in beef cattle, sheep, and more recently, elk and goats. Clinical bovine lesions typically appear on the plantar surface of the hind foot from the interdigital space and heel bulb to the accessory digits, with a predilection for skin–horn junctions. Lesions present as a painful ulcerative acute or chronic inflammatory process with differing degrees of severity. This variability reflects disease progression and results in a number of different clinical descriptions with overlapping pathologies that ultimately have a related bacterial etiology. The goal of this review article is to provide a concise overview of our current understanding on digital dermatitis disease to facilitate clinical recognition, our current understanding on the causative agents, and recent advances in our understanding of disease transmission.

    Bovine digital dermatitis (BDD) is an infective foot disease commonly reported in dairy cattle where Treponema are considered as the primary causative infectious agents. There still remains little definitive information on the etiology of BDD in beef cattle suggesting further investigations are warranted. Beef BDD lesions (n=34) and healthy beef foot tissues (n=38) were analysed by PCR for three BDD-associated Treponema phylogroups and also for Dichelobacter nodosus and Fusobacterium necrophorum. Spirochete culture was attempted on all BDD lesion samples. One or more BDD-associated Treponema phylogroups were detected in 100% of beef BDD lesions. "Treponema medium/Treponema vincentii-like", "Treponema phagedenis-like" and Treponema pedis spirochetes were identified in 27/34 (79%), 31/34 (91%) and 24/34 (71%) of BDD lesions, respectively. No BDD-associated treponeme DNA was amplified from beef healthy foot tissues. D. nodosus and F. necrophorum were present in 24/34 (71%) and 15/34 (44%) of lesions and 10/38 (26%) and 12/38 (32%) of healthy foot tissues, respectively. Twenty spirochetes were isolated from beef BDD lesions; 19 were representatives of the three BDD-associated Treponema phylogroups. One spirochete isolate shared less than 97% 16S rRNA gene similarity to the three cultivable BDD-associated Treponema phylogroups and therefore may represent a novel taxa of Treponema. Upon comparison, sheep contagious ovine digital dermatitis (CODD), dairy cattle and beef cattle BDD lesions appear to have extremely similar bacteriological data and therefore provides evidence of a shared etiopathogenesis posing concerns for cross-species transmission.

    Full Text Available This report characterizes the digital dermatitis (DD lesions in the accessory digits of dairy cows and presents data on the applied therapy. Fifteen Holstein cattle with DD affecting the accessory digits of the hindlimbs from four dairy farms with previous history of DD were evaluated. Lesions were excised, the wounds were sutured, and a topical application of oxytetracycline powder covered by bandaging was associated with a single parenteral administration of long acting oxytetracycline IM (20mg/kg. Tissue samples were obtained for histopathology and transmission electronic microscopy (TEM. Lesions from all the animals were recuperated 15 days after surgical procedure. Overal, most DD lesions were papillomatous epidermal projections or wartlike verrucous lesions. Histopathologically, samples revealed hyperplasia of epidermis with hyperkeratosis, several mitoses in the stratum basale and elongated rete ridges in the superficial and middle dermis. TEM revealed long, thin spirochete-like bacteria. Morphologic features of lesions and its response to therapy were comparable to those described for DD.

    Bovine Digital Dermatitis (DD) is a leading cause of lameness in dairy cattle. DD is reportedly increasing in prevalence in beef cattle feedlots of the US. The exact etiologic agent(s) responsible for the disease have yet to be determined. Multiple studies have demonstrated the presence of a variety of Treponema spp. within lesions. Attempts to reproduce clinically relevant disease using pure cultures of these organisms has failed to result in lesions that mirror the morphology and severity of naturally occurring lesions. This manuscript details the systematic development of an experimental protocol that reliably induces digital dermatitis lesions on a large enough scale to allow experimental evaluation of treatment and prevention measures. In total, 21 protocols from five experiments were evaluated on their effectiveness in inducing DD lesions in 126 Holstein calves (504 feet). The protocols varied in the type and concentration of inoculum, frequency of inoculation, duration the feet were wrapped, and type of experimental controls need to validate a successful induction. Knowledge gained in the first four experiments resulted in a final protocol capable of inducing DD lesions in 42 of 44 (95%) feet over a 28 day period. All induced lesions were macroscopically and microscopically identified as clinical DD lesions by individuals blinded to protocols. Lesions were also located at the site of inoculation in the palmer aspect of the interdigital space, and induced clinically measurable lameness in a significant portion of the calves. Collectively these results validate the model and provide a rapid and reliable means of inducing DD in large groups of calves. PMID:27119564

    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.

    Full Text Available Abstract Digital dermatitis (DD is a contagious disease of cattle affecting the skin adjacent to the claws. Disease dynamics of DD have been described to some extend, but we still need to quantify the duration of lesions and look into non-treatment factors affecting this. The aim of this study was to estimate the duration of lesions due to DD and to evaluate parity and lactation stage as potential risk factors for longer duration of such lesions. An estimate of the duration of lesions will be a valuable parameter in the evaluation of the economic impact of the disease and will additionally allow estimates of incidence based on prevalence figures. From May 2007 until November 2008, lesions associated with DD in the hind legs of 151 Danish Holstein cows at the Danish Cattle Research Centre were clinically scored on fifteen occasions. The mean interval between recordings was 39 days. Onset and end of each new case were estimated as midway between recordings prior to a change in the presence or absence of a lesion. Kaplan-Meier survival functions and Cox proportional hazard regression were performed to estimate the duration and analyse differences in the duration of lesions between primi- and multiparous cows and between different stages in lactation at onset of the lesion. The median duration of lesions were estimated to be 42 days, less than most previous published estimates. The relatively aggressive regime of topical treatment in the study herd might have shortened the duration of the lesions. Furthermore the comparatively long interval between recordings introduced an element of uncertainty in this estimate. No significant effects of parity or days in milk at lesion onset on the duration of DD were found using these data though lesions developed earlier in the lactation may have a longer duration. Further data would be needed to confirm the latter.

    Digital dermatitis (DD) is a contagious disease of cattle affecting the skin of the claw. The disease presents with a range of severities and can be associated with lameness. Information about the disease dynamics of DD is scarce. Parity and lactation stage have been identified as risk factors for DD and studies have also indicated that not all cows are equal regarding their risk of recurrent disease and prospects for cure from DD. The aim of this study was to investigate host heterogeneity to DD and to identify disease patterns of DD and factors associated with the development and resolution of lesions. In three commercial dairy herds, 742 lactating cows were observed for DD lesions weekly for 11 or 12 weeks. The effects of parity, lactation stage and duration of preceding episode on the hazard of transitions between healthy and lesion states were analysed using a multilevel multistate discrete-time model. One or more DD lesions were observed in 460 cows and lesions were observed in 2426 out of 10,585 observations. In total, 1755 uncensored episodes with DD lesions were observed. Early lactation was associated with a reduced risk of developing lesions compared with mid and late lactation. Lesions that developed in late lactation had a greater likelihood of resolution compared with lesions that developed during early lactation. There was a reduced risk of lesions developing in parity 3 compared with parity 1 cows, but an increased risk of lesions developing in parity 2 compared with parity 1 cows. In the present study, the mean duration of uncensored DD episodes was 1.7 weeks indicating that the duration of the majority of DD lesions might be shorter than the 42 days reported previously. The transitions between disease states suggest that DD is a dynamic disease, and that the early stage lesions are more transient than expected from previous studies. We conclude that studies with shorter observation intervals than one week are needed to fully understand and

    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

  18. Genetic parameters for digital dermatitis and correlations with locomotion, production, fertility traits, and longevity in Holstein-Friesian dairy cows.

    Onyiro, O M; Andrews, L J; Brotherstone, S

    2008-10-01

    Heritability of digital dermatitis (DD) and correlations between DD and type traits related to legs and feet were estimated from a linear animal model. Data comprised 93,391 national type evaluation records of pedigreed first-lactation Holstein-Friesian cows that calved from 2002 through 2006. At the time of classification, cows were housed in different housing systems (i.e., cubicles, straw yards, slatted or loafing yards) and on pasture. The type traits evaluated were locomotion score (LOCO), rear legs side view (RLS), foot angle (FA), bone quality and leg and feet composite (L&F). In addition, cows were examined for DD lesions at classification. The relationships among these type traits, lifespan (LS), production (milk and fat), fertility (calving interval and 56-d nonreturn) and DD were examined by estimating the approximate genetic correlations from sire estimated breeding values. The study also evaluated the association between DD and the housing systems as well as the general conditions of the farm flooring where classification took place. In general, cows on pasture were less susceptible to DD than cows in other housing systems, whereas the association between DD and the flooring conditions was counterintuitive. Heritability estimate for DD was 0.011 on the 0/1 scale, which is equivalent to 0.029 on the assumed underlying normally distributed scale. Bone quality, LOCO, and L&F had moderate to high negative genetic correlations with DD, indicating that flatter, more refined bones, higher LOCO, and better L&F were associated with less incidence of DD. The genetic correlations between DD, RLS, and FA were not significantly different from zero. Digital dermatitis had moderate but negative genetic correlations with LS and milk and fat, suggesting that breeding for resistance to DD will result in an increase in both longevity and production. Cows affected with DD had a slightly shorter calving interval than healthy cows, an association found to be mediated

    Cornflower (Centaurea cyanus) honey can be characterized by a greenish yellow color and an intense flavor with a bitter aftertaste. Because cornflower honey contains only a limited amount of pollen for the verification of its floral origin, one objective was the characterization of its polyphenol and norisoprenoid contents to assign floral markers. Here, lumichrome (18.8-43.5 mg/kg), 7-carboxylumichrome, (Z/E)-3-oxo-retro-α-ionol, and 3-oxo-α-ionol appeared to be quite suitable for distinguishing cornflower honey from other unifloral honeys. Additionally, due to its comparably high hydrogen peroxide content (0.5-0.9 mM/h) and the associated antibacterial activity, cornflower honey was used as an alternative treatment of digital dermatitis on an organic dairy farm. Cows affected by this hoof disease often show severe lameness and a subsequent decline in milk yield and loss of body condition. The cows' hooves treated with cornflower honey showed significantly faster healing than the control group without any treatment. PMID:23140532

  20. Economic impacts of reduced milk production associated with papillomatous digital dermatitis in dairy cows in the USA.

    2006-05-01

    The goal of this study was to measure the economic impacts of reduced milk production associated with papillomatous digital dermatitis (PDD) in dairy cows in the USA, and of specific risk factors for PDD, in 1996. The method applied was an economic-welfare analysis of producer and consumer surplus, with the GUM Workbench used to analyse uncertainties in the measurements. Reduced milk production associated with PDD was found to reduce consumer surplus by Dollars 750 million +/- Dollars 580 million, and to increase the economic surplus of producers by Dollars 560 million +/- Dollars 470 million, with a net economic loss of Dollars 190 million +/- Dollars 130 million. An examination of the economic effects of specific epidemiologic risk factors for PDD showed that having dairy cows that were not born on the operation had important economic consequences associated with the disease, as did the type of land to which dairy cows had access during the winter months and the type of flooring on which cows walked. Washing hoof-trimming equipment between cows was an important biosecurity measure that was associated with reduced PDD. The epidemiologic model used also implicated hoof trimmers who trimmed cattle hooves on other operations as having an important economic impact associated with this disease, although this finding may have been erroneous.

    Full Text Available This essay had the scope of characterizing anatomic-pathological aspects of digital dermatitis wounds in distinct development phases. The essay was carried out from August 2004 and November 2005, using 40 cows distributed in four groups of ten animals each. Group I (GI consisted of clinically healthy animals, and groups II (GII, III (GIII and IV (GIV, consisted of animals bearing wounds in initial, erosive and proliferative phases, respectively. In GII histological observations were corneal stratus’ thickening, necrosis, hiperplasia, acanthosis, espongiosis and hyperqueratosis. In GIII it was observed hyperemia, ulcers, granulation tissue, hemorrhage and, microscopically, corneal layer thickening, paraqueratosis and multifocal necrosis. In GIV lesions of verrucous aspect, presence of fur, papillary projections were observed macroscopically, and, at histological examination, destruction of corneal layer and epidermis along with necrosis in all samples from the group.  Concerning the microbiota, fungi were not observed in any group. As for bacteria, mixed flora was observed, especially spirochetes, in GII, GIII e GIV. Finally, it was concluded that histological alterations in distinct phases of digital dermatitis may commonly be present, differing in terms of severity. The presence of spiral microorganisms suggests their association with etiopathogenesis.

  4. Experimental Investigation on the Mechanical Behavior of Bovine Bone Using Digital Image Correlation Technique

    2015-01-01

    Full Text Available In order to understand the fracture mechanisms of bone subjected to external force well, an experimental study has been performed on the bovine bone by carrying out the three-point bending test with 3D digital image correlation (DIC method, which provides a noncontact and full field of displacement measurement. The local strain and damage evolution of the bone has been recorded real time. The results show that the deflection measured by DIC agrees well with that obtained by the displacement sensor of the mechanical testing machine. The relationship between the deflection and the force is nearly linear prior to reaching the peak strength which is about 16 kN for the tested bovine tibia. The full-field strain contours of the bone show that the strain distribution depends on not only the force direction, but also the natural bone shape. The natural arched-shape bovine tibia bone could bear a large force, due to the tissue structure with high strength, and the fracture propagation process of the sample initiates at the inner side of the bone first and propagates along the force direction.

    Diaper dermatitis is one of the most common skin diseases during infancy and childhood. It is a type of irritant contact eczema resulting from a complex interaction between urine and feces under occlusive conditions in combination with the hyperhydration of the stratum corneum, pressure and friction under the diaper. These conditions pave the way for Candida albicans infection, which is often associated with diaper dermatitis. The anogenital region can be involved by a variety of dermatoses, so a precise skin examination, detailed history and sometimes histologic examination are needed for a precise diagnosis. Therapeutically, frequent diaper changes and adequate skin care are most important. PMID:21882101

  13. Compositae dermatitis

    Directory of Open Access Journals (Sweden)

    Jovanović Mirjana

    2003-01-01

    Full Text Available Introduction Compositae dermatitis is an allergic contact dermatitis caused by plant species of the Compositae family. The first report of a cutaneous reaction to the Chrysanthemum genus was made by Howe JS in 1887. In 1895 Maiden JH reported about skin lesions among men working with Tagetes minute Case reports of contact allergic-ragweed dermatitis appeared in the American literature as early as 1919. The North American feverfew - Parthenium Hysterophorus was brought to India from America in 1956 and it caused thousands of cases of so-called parthenium dermatitis. Ragweed and parthenium dermatitis became prototypes for the classic, so-called 'airborne' Compositae dermatitis, that affects primarily exposed skin surfaces, and produces a universal erythroderma. Epidemiology The frequency of contact allergy to Compositae in Europe is higher than previously believed. It occurs most frequently in middle-aged and elderly persons, but also in all age groups During the two past decades a more equal sex ratio has been established. The prevalence varies from 0.7-1.4% in the general population, up to 4.5% among occupationally exposed persons. Compositae allergy is among the top ten contact sensitivities in Europe. In North Europe plants were the cause of 4.4% cases of occupational allergic contact dermatitis. Etiology and pathogenesis Among cultivated Compositae plants, Chrysanthemum is considered to be a major sensitizer in Europe (60%. Among the edible types, it is lettuce - Lactuca sativa and endive Cichorium endivia (20-30%, and wild-growing feverfew - Tanacetum parthenium (70-90%, tansy - Tanacetum vulgare (54%, and dandelion - Taraxacum officinale (65%. Sesquiterpene lactones are the main sensitizers of the Compositae family. Other components thiophenes and acetylenes are said to elicit only phytophotodermatitis, but recent studies have demonstrated that some thiophenes and benzofuran derivates possess not only phototoxic activity, but also

    Full Text Available Seborrehic dermatitis is a common inflammatory skin condition occurring most often on the face, scalp and chest. It affects between 1-3 of adults and is more common in males. It is especially common in adolescents, young adults and people older than 50 years old. Frequently, it involves scalp, nasolabial folds, ears, eyebrows and sternum. It is characterised by symetriccal erythematous papules and plaques with greasy yellow squams. The condition has multifactorial etiology and stress, atopy, Pityrosporum ovale, central nervous system diseases and drugs are the mostly accused factors. Antiinflammatory, antimicotic and immunomodulatory drugs are used for therapy. In resistent cases, systemic steroids, isotretinoin, antimycotics and phototherapy can be tried. In this review, the literature associated with the etiology, clinical manifestations and treatment of seborrheic dermatitis is overviewed.

    2016-08-01

    In 2013, a questionnaire was used to gather data on risks for introduction, and factors associated with prevalence, of contagious ovine digital dermatitis (CODD). There were 1136 (28.4%) usable responses from 4000 randomly selected sheep farmers in England. CODD was present in 58% (662) of flocks, with a reported prevalence of CODD lesions of 2.3%. The geometric mean period prevalence of all lameness was 4.2% and 2.8% in CODD positive and negative flocks respectively. Factors associated with a greater risk of presence of CODD were purchasing replacement ewes, not always checking the feet of sheep before purchase, not isolating purchased sheep, foot bathing returning ewes, foot trimming the flock more than twice in the year all compared with not doing these activities and increasing log10 flock size. Farmers who vaccinated sheep with Footvax™ were less likely to report presence of CODD. Factors associated with increasing prevalence of CODD lesions were not always checking the feet of purchased sheep, flocks that mixed with other flocks and sheep that left the farm for summer grazing and later returned. In addition, flocks where farmers followed the current recommended managements for control of footrot, had a lower prevalence of CODD whilst those who used foot bathing and where feet bled during routine foot trimming had a higher prevalence of CODD. The prevalence of CODD decreased with each log10 increase in flock size. We conclude that CODD is an infectious cause of lameness in sheep of increasing importance in GB. Introduction is linked to poor biosecurity with one likely source of the pathogen being introduction of or mixing with infected sheep. As with footrot, prevalence of CODD was lower in flocks where farmers focused on individual treatment to manage lameness and avoided foot bathing and trimming feet. We conclude that most of the currently recommended biosecurity and treatment approaches to control footrot in GB are also effective for control of CODD

    Full Text Available Abstract Atopic dermatitis (AD is a common, chronic skin disorder that can significantly impact the quality of life of affected individuals as well as their families. Although the pathogenesis of the disorder is not completely understood, it appears to result from the complex interplay between defects in skin barrier function, environmental and infectious agents, and immune abnormalities. There are no specific diagnostic tests for AD; therefore, the diagnosis is based on specific clinical criteria that take into account the patient’s history and clinical manifestations. Successful management of the disorder requires a multifaceted approach that involves education, optimal skin care practices, anti-inflammatory treatment with topical corticosteroids and/or topical calcineurin inhibitors (TCIs, the use of first-generation antihistamines to help manage sleep disturbances, and the treatment of skin infections. Systemic corticosteroids may also be used, but are generally reserved for the acute treatment of severe flare-ups. Topical corticosteroids are the first-line pharmacologic treatments for AD, and evidence suggests that these agents may also be beneficial for the prophylaxis of disease flare-ups. Although the prognosis for patients with AD is generally favourable, those patients with severe, widespread disease and concomitant atopic conditions, such as asthma and allergic rhinitis, are likely to experience poorer outcomes.

    Full Text Available In order to recognize early symptoms of melanoma, the lethal cancer of the skin, our group is developing pattern recognition and machine learning tools that may help medical doctors in the melanoma diagnosis. Since in the machine learning approach data from diversified sources are required, in this article we present the Java-based Dermat 1.0 application, a medical software system for management of dermoscopy data and the patients follow-up documentation. The chief objective for this system is to integrate all the management activities (image acquisition, anamneses, medical documentation and annotations into a self-content optimal data base system. Such an integrated approach to digital dermoscopy and management of the patient data between the visits is crucial in comparing the results, storing/retrieving/transmitting dermoscopic images and making a proper and early diagnosis. The Dermat application is distributed among dermatological clinics and private practitioners in accordance to the 'tool-for-the-data' model.

    The quality control of cell lines used in research and industry is critical to ensure confidence in experimental results and to guarantee the safety of biopharmaceuticals to consumers. The BVDV is a common adventitious agent in many cell lines. We preliminarly evaluate the use of Digital Droplet PCR (ddPCR) for the detection and enumeration of genome copies of BVDV in cell culture and on FBS. The application of a commercial Real-Time PCR kit with the ddPCR technique was successful on different matrices. The technique allowed the absolute quantification of the genome without the use of calibration standards, suggesting its promising application on the development of reference materials for quantification of nucleic acids.

    Several chronic progressive vascular diseases, such as laminitis, show vasocontractile dysfunction that might evolve into reperfusion injury and/or vessel structural remodelling, which may be traced back to aberrant endothelial function. In the present study, the vasomotor responses of bovine digital veins (BDVs) to 5-hydroxytryptamine (5-HT) were investigated in blood vessels, with and without endothelium present, and in samples deprived of endothelium before or after overnight incubation in tissue culture medium, to evaluate the effects of short- and long-term endothelial damage on vascular smooth muscle (VSM) reactivity. No significant effects were observed in the blood vessels tested immediately after the removal of endothelium. In contrast, a significant increase in VSM reactivity to 5-HT was seen in vessels incubated without endothelium. This long-term change in smooth muscle reactivity was prevented by exposure to the nitric oxide (NO) donor nitroprusside (P digital veins in animals affected with laminitis. PMID:26670334

    1998-09-01

    Hand dermatitis is common in workers in the horticultural industry. This study determined the prevalence of hand dermatitis in workers of Alstroemeria cultivation, investigated how many workers had been sensitized by tulipalin A (the allergen in Alstroemeria) and took stock of a wide range of determinants of hand dermatitis. The 12-month period prevalence of major hand dermatitis amounted to 29.5% whereas 7.4% had minor dermatitis. Of these workers, 52.1% were sensitized for tulipalin A. Several personal and work-related determinants played a role in the multifactorial aetiology of hand dermatitis. Factors which showed a significant relationship with major hand dermatitis were: female sex, atopic dermatitis, chapped hands and the frequency of washing hands. It may be concluded that the Alstroemeria workers are a population at risk of developing contact dermatitis and it might be useful to carry out an educational campaign to lower the high prevalence.

    2008-06-01

    Full Text Available Occupational contact dermatitis accounts for 90% of all cases of work-related cutaneous disorders. It can be divided into irritant contact dermatitis, which occurs in 80% of cases, and allergic contact dermatitis. In most cases, both types will present as eczematous lesions on exposed parts of the body, notably the hands. Accurate diagnosis relies on meticulous history taking, thorough physical examination, careful reading of Material Safety Data Sheets to distinguish between irritants and allergens, and comprehensive patch testing to confirm or rule out allergic sensitization. This article reviews the pathogenesis and clinical manifestations of occupational contact dermatitis and provides diagnostic guidelines and a rational approach to management of these often frustrating cases.

    Foot dermatitis is a widespread condition, affecting men and women of all ages. Because of the location, this condition may present as a debilitating problem to those who have it. Allergic contact dermatitis involving the feet is frequently due to shoes or socks. The allergens that cause shoe dermatitis can be found in any constituent of footwear, including rubber, adhesives, leather, dyes, metals, and medicaments. The goal of treatment is to identify and minimize contact with the offending allergen(s). The lack of product information released from shoe manufacturers and the continually changing trends in footwear present a challenge in treating this condition. The aim of this study is to review the current literature on allergic contact shoe dermatitis; clinical presentation, allergens, patch testing, and management will be discussed. PubMed and MEDLINE databases were used for the search, with a focus on literature updates from the last 15 years. PMID:25000234

    Nickel is the most important sensitizer in Lagos, with an incidence of 12.3% of 453 patients tested. There was no sex difference, as the wearing of necklaces and bracelets was equally fashionable among both sexes. Housewife eczema is not common, probably because of hardening. Dermatitis from additives in the processing of leather and rubber footwear was the next most common. Chromate sensitivity comes usually from leather or cement.

    Hand dermatitis is a common skin complaint. We use our hands to explore our environment; subsequently, our hands are in frequent contact with potential allergens and irritants. Patients with hand dermatitis may present to their allergist with this complaint. Approaching the diagnosis and treatment of hand dermatitis can be challenging, as both internal and external factors may contribute to the overall condition. Furthermore, the differential diagnosis of hand dermatitis is broad and the cause often multifactorial. Obtaining a thorough history and performing a focused examination may help the clinician differentiate between multiple causes of hand dermatitis. Numerous treatment options exist for hand dermatitis, and new potential treatments are in development as well. We aim to provide the allergist with a streamlined toolkit for help in the diagnosis and management of hand dermatitis. PMID:25228264

    Atopic dermatitis is a chronic inflammatory skin condition with drastic impacts on pediatric health. The pathogenesis of this common disease is not well understood, and the complex role of the skin microbiome in the pathogenesis and progression of atopic dermatitis is being elucidated. Skin commensal organisms promote normal immune system functions and prevent the colonization of pathogens. Alterations in the skin microbiome may lead to increased Staphylococcus aureus colonization and atopic dermatitis progression. Despite the evidence for their important role, probiotics have not been deemed efficacious for the treatment of atopic dermatitis, although studies suggest that probiotics may be effective at preventing the development of atopic dermatitis when given to young infants. This review will cover the most recent published work on the microbiome and pediatric atopic dermatitis. PMID:26388516

    Two patients with contact dermatitis due to the natural product propolis (bee glue) are reported. They presented perioral eczema and stomatitis which were recalcitrant until propolis was considered as the cause. Patch tests with propolis preparations were positive in both patients, and, furthermore, in the second patient the lesions relapsed after provocation tests. European standard patch test including balsam of Peru were negative. The complexity of propolis, its supposed anti-inflammatory effect due to flavonoids, and the sensitizing agents originating mainly from the poplar trees are discussed together with the cross-sensitization to balsam of Peru. Contact dermatitis due to propolis should be considered in unexplained eczemas, mainly perioral but also in other areas, as propolis preparations are available also as ointments and cosmetic creams.

    A juvenile female hooded seal (Cystophora cristata) and a juvenile male harp seal (Phoca groenlandica) stranded separately on the New Jersey (USA) coast and were taken to a marine mammal rehabilitation center. Both were lethargic and emaciated, had dermatitis, and died. Histologic skin lesions in the seals were similar and consisted of epidermal and follicular epithelial hyperplasia, hyperkeratosis, degeneration, and necrosis. The most distinctive finding was extensive syncytial zones bounded superficially by hyperkeratosis and deeply by hyperplastic basal cells. Eosinophilic intracytoplasmic inclusion bodies were present in epithelial cells. Morbilliviral antigen was demonstrated in the skin lesions by immunohistochemistry. Phocine distemper virus was detected in the skin by reverse transcription polymerase chain reaction and a phocine distemper virus-specific probe using the Southern blot technique. This is the first report of morbilliviral dermatitis in marine mammals. PMID:11732810

    2015-12-01

    Occupational contact dermatitis is generally caused by haptens but can also be induced by proteins causing mainly immunological contact urticaria (ICU); chronic hand eczema in the context of protein contact dermatitis (PCD). In a monocentric retrospective study, from our database, only 31 (0.41%) of patients with contact dermatitis had positive skin tests with proteins: 22 had occupational PCD, 3 had non-occupational PCD, 5 occupational ICU and 1 cook had a neutrophilic fixed food eruption (NFFE) due to fish. From these results and analysis of literature, the characteristics of PCD can be summarized as follows. It is a chronic eczematous dermatitis, possibly exacerbated by work, suggestive if associated with inflammatory perionyxix and immediate erythema with pruritis, to be investigated when the patient resumes work after a period of interruption. Prick tests with the suspected protein-containing material are essential, as patch tests have negative results. In case of multisensitisation revealed by prick tests, it is advisable to analyse IgE against recombinant allergens. A history of atopy, found in 56 to 68% of the patients, has to be checked for. Most of the cases are observed among food-handlers but PCD can also be due to non-edible plants, latex, hydrolysed proteins or animal proteins. Occupational exposure to proteins can thus lead to the development of ICU. Reflecting hypersensitivity to very low concentrations of allergens, investigating ICU therefore requires caution and prick tests should be performed with a diluted form of the causative protein-containing product. Causes are food, especially fruit peel, non-edible plants, cosmetic products, latex, animals. PMID:26242922

    Full Text Available Cheyletiellosis (cheyletiella dermatitis is a dermatitis caused by cheyletiella mites that are seen more commonly in cats, dogs and rabbits all over the world. Cheyletiella blakei, which is naturally hosted by cats, causes infestations in people, especially who are in close contact with infested cats. The diagnosis of cheyletiellosis in humans is established by the suspicion of physician or veterinarian and demonstration of the mites in cats. If not suspected, cheyletiellosis may be thought as delusions of parasitosis and may be undiagnosed. A 48-year-old woman presented to our clinic with red, pruritic papules on the chest, abdomen, arms and anterior thighs. There was no remission of the complaints of the patient after 3 days of topical corticosteroid treatment. Following more detailed examination and medical history, cheyletiellosis was suspected. The diagnosis was confirmed by a veterinary control of the cat that the women had started feeding at home about 15 days ago. Although cheyletiella dermatitis is not uncommon, most cases are undiagnosed because it is not a well-known dermatosis by dermatologists. As far as we know, there is no previously reported cheyletiella case in our country. (Turk­derm 2011; 45: 213-5

    1985-04-01

    A study was carried out on 50 workers in a floriculture centre to evaluate the incidence of contact dermatitis to Alstroemeria. 3 subjects gave positive reactions to aqueous and ethanolic extracts of cut flowers, stems and leaves. By column chromatography, the allergen was isolated and its chemical structure identified as 6-tuliposide A by proton magnetic resonance and carbon-13 magnetic resonance. Only 6-tuliposide A was isolated from cut flowers, and this gave positive reactions when patch tested at 0.01%; a-methylene-gamma-butyrolactone at 10(-5) (v/v) was positive in the same 3 subjects. Other lactones (gamma-methylene-gamma-butyrolactone, alantolactone, isoalantolactone) were negative at all concentrations used. PMID:3160533

    Two female florists developed dermatitis of the fingertips. Patch testing revealed allergic contact dermatitis to the flower, Alstroemeria, used in floral arrangements. They had positive patch tests to portions of Alstroemeria, and to tuliposide A, the allergen in this plant. Vinyl gloves were not helpful since tuliposide A readily penetrates through these gloves. Nitrile gloves may be protective since they prevented positive patch test to tuliposide A. PMID:2967676

    Cymbidium has known antibacterial and antiedema activity and has been used as an ingredient in cosmetics and fragrances. The effects of Cymbidium ethanol extract (CYM) on allergic response and the underlying mechanisms of action have not been reported. Therefore, the purpose of this study was to determine the effect of CYM on allergic responses. Topical application of CYM was effective against immunoglobulin E (IgE)/dinitrophenyl-conjugated bovine serum albumin- (DNP-BSA-) induced degranulation of RBL-2H3 cells and anaphylaxis in ICR mice. An allergic dermatitis-like mouse model was used to evaluate the therapeutic potential of CYM in vivo. Continuous application of 2,4-dinitrochlorobenzene (DNCB) not only induced dermatitis in ICR mice but also aggravated the skin lesioning. However, the application of CYM decreased skin lesion severity, scratching behavior, and IgE levels. In addition, CYM downregulated the expression of the proinflammatory cytokines interleukin- (IL-) 4, IL-13, and tumor necrosis factor- (TNF-) α. Studies of signal transduction pathways showed that CYM suppressed the phosphorylation of spleen tyrosine kinase (Syk), an upstream molecule. It also inhibited the phosphorylation of Akt, phospholipase C- (PLC-) γ, and mitogen-activated protein kinase kinase kinase (MEKK). These results indicate that CYM may be effective in preventing and reducing allergic response and may have therapeutic potential as an antiallergic agent in disorders such as atopic dermatitis.

  3. Systemic contact dermatitis

    2016-02-01

    Full Text Available Systemic contact dermatitis (SCD is a skin inflammation occurring in a patient after systemic administration of a hapten, which previously caused an allergic contact skin reaction in the same person. Most frequently, hypersensitivity reactions typical for SCD occur after absorption of haptens with food or inhalation. Haptens occur mainly in the forms of metals and compounds present in natural resins, preservatives, food thickeners, flavorings and medicines. For many years, several studies have been conducted on understanding the pathogenesis of SCD in which both delayed type hypersensitivity (type IV and immediate type I are observed. Components of the complement system are also suspected to attend there. Helper T cells (Th (Th1 and Th2, cytotoxic T lymphocytes (Tc, and NK cells play a crucial role in the pathogenesis of SCD. They secrete a number of pro-inflammatory cytokines. In addition, regulatory T cells (Tregs have an important role. They control and inhibit activity of the immune system during inflammation. Tregs release suppressor cytokines and interact directly with a target cell through presentation of immunosuppressive particles at the cell surface. Diagnostic methods are generally the patch test, oral provocation test, elimination diet and lymphocyte stimulation test. There are many kinds of inflammatory skin reactions caused by systemic haptens’ distribution. They are manifested in a variety of clinical phenotypes of the disease.

    2011-12-01

    Full Text Available Atopic dermatitis (AD is a chronic inflammatory skin disorder that typically occurs during childhood especially in the first year of life, with a variable frequency from 10% to 30%. Recent studies have shown that in Europe among 10-20% of children with AD suffer from this disorder also in adolescence. AD is a chronic inflammatory skin disease with a typical onset in the first years of life and with a 10- 30% prevalence among young children. AD prevalence in adolescence has been estimated around 5-15% in European countries. AD persists from childhood through adolescence in around 40% of cases and some risk factors have been identified: female sex, sensitization to inhalant and food allergens, allergic asthma and/or rhinoconjunctivitis, the practice of certain jobs. During adolescence, AD mainly appears on the face and neck, often associated with overinfection by Malassezia, and on the palms and soles. AD persistence during adolescence is correlated with psychological diseases such as anxiety; moreover, adolescents affected by AD might have problems in the relationship with their peers. Stress and the psychological problems represent a serious burden for adolescents with AD and cause a significant worsening of the patients’ quality of life (QoL. The pharmacological treatment is similar to other age groups. Educational and psychological approaches should be considered in the most severe cases.

    Tobacco and tobacco smoke are strongly associated with various skin conditions, among which contact dermatitis is of prime importance. The aetiological and clinical aspects vary according to the different tobacco production and processing steps. Contact dermatitis is frequent in tobacco harvesters, curers and cigar makers, whereas it rarely affects smokers and, only exceptionally, cigarette packaging workers. The skin sites involved also vary, according to whether the exposure is occupational or non-occupational. Tobacco contact irritation is far more frequent than contact allergy. The sensitizing compound in tobacco is unknown; nicotine, while highly toxic, does not seem to cause sensitization, except in rare cases. Besides natural substances, several compounds are added to tobacco during processing and manufacturing. For this reason, identifying the aetiological factors is exceedingly difficult. Another important aspect to take into account is the co-causative role of tobacco in eliciting or exacerbating contact dermatitis in response to other agents, occupational or extra-occupational.

    2000-05-01

    Allergic contact dermatitis (ACD) in dentistry may affect dentists and orthodontists, technicians, nurses and patients. Changes to dental practice in recent years have altered the reported frequencies of allergens causing ACD in both dental personnel and patients. Allergic contact dermatitis to medicaments, metals and glutaraldehyde were previously common allergens in dentistry; however, widespread adoption of rubber gloves by staff has resulted in a significant increase in ACD to glove allergens in both dental staff and their patients, while affording protection against the traditional allergens. Both public concerns about potential toxicity of metals in oral restorations and a greater demand for cosmetic dentistry, have resulted in greater use of acrylics and resins by dental personnel, exposing them to highly allergenic materials. Dermatologists need to be aware of the newer allergenic materials used in dentistry in order to correctly manage skin diseases in this high-risk group. PMID:10812698

    2015-01-01

    Diaper (napkin) dermatitis is an acutely presenting inflammatory irritant contact dermatitis of the diaper region. It is one of the most common dermatologic diseases in infants and children. In the past, the disease was thought to be caused by ammonia; however, a number of factors, such as friction, wetness, inappropriate skin care, microorganisms, antibiotics, and nutritional defects, are important. Diaper dermatitis commonly affects the lower parts of the abdomen, thighs, and diaper area. Involvement of skin fold regions is typical with diaper dermatitis. At the early stages of the disease, only dryness is observed in the affected area. At later stages, erythematous maceration and edema can be seen. Secondary candidal and bacterial infections can complicate the dermatitis. In the differential diagnosis of the disease, allergic contact dermatitis, intertrigo, psoriasis, atopic and seborrheic dermatitis, and the other diseases should be considered. Causes of the disease should be determined and eliminated primarily. Families need to be informed about the importance of a clean, dry diaper area and the frequency of diaper changes. The use of superabsorbent disposable diapers has decreased the incidence of the disease. Soap and alcohol-containing products should be avoided in cleaning the area. In some cases, corticosteroids and antifungal agents can be administered. If necessary, antibacterial agents and calcineurin inhibitors can also be beneficial. PMID:26051065

    2008-01-01

    Patients wearing a prosthesis face a wide variety of medical problems. Skin complications have long been recognized, but their prevalence is still unknown. The most frequently reported disorders are allergic contact dermatitis (ACD), acroangiodermatitis, epidermoid cysts, epidermal hyperplasia, follicular hyperkeratosis, verrucous hyperplasia, bullous diseases, hyperhidrosis, infections, malignancies, and ulcerations. Contact dermatitis represents one-third of the dermatoses in amputees wearing prostheses. All patients who are suspected of having ACD should be patch tested with standard allergen series as well as materials from the patient's own prosthesis, topical medicaments, moisturizers, and cosmetics. We report a patient with an ACD to mixed dialkyl thiourea present in the rubber parts of his below-the-knee prosthesis. Thiourea derivates are used as accelerators in the manufacture of chloroprene rubber and as fixatives in photography and photocopy paper. Allergy to thiourea is relatively uncommon; different studies have shown a prevalence of 0.7% up to 2.4% in patch-tested patients. Thiourea derivates are often the allergic sources in ACD involving high-grade rubber products made of neoprene such as diving suits, protective goggles, knee braces, and continuous positive airway pressure masks. They are also present in the rubber material of prostheses, as in the case of our patient. PMID:18413115

    Occupational dermatosis are frequent among healthcare workers. Irritant hand dermatitis is more common than allergic contact dermatitis. It is enhanced by the exposure to irritants: water, detergents, disinfectants and a history of atopic dermatitis. Natural rubber latex contained in rubber gloves can induce contact urticaria or generalized immediate allergic reactions. Contact eczema can be induced by rubber accelerators such as thiurams, disinfectants (glutaraldehyde, dodecyldimethylammonium). Nurses can become sensitized to handled drugs (antibiotics, propacetamol...). These occupational allergies have to be diagnosed, because sensitized nurses can develop severe generalized cutaneous adverse drug reactions if they are systemically exposed to the same drug than those that has previously induced an occupational contact allergy.

    Objective To describe the ocular complications of 62 patients with active atopic dermatitis( AD) during the period of 2003 2006. Methods Routine ophthalmic examinations, including slit-lamp microscope, indirect ophthalmoscope or Goldmann three-mirror lens, A-scan and B-scan ultrasound, ultrasound biomicroscope (UBM) and corneal topography, as well as tear film break-up time (BUT) and Schirmer tests were carried out. Results Cataract (28 eyes), keratoconjunctivitis (42 eyes), superficial punctate keratopathy (45 eyes) and tear function abnormality ( 76 eyes) were major ocular complications in AD patients. Retinal detachment (6 eyes) was the most severe ocular complication in the AD patients. Conclusion Ocular complications are common in AD patients and a very careful examination of eyes is essential in treating AD patients. If the eyes can be examed carefully and in time, some operations and severe complications can be avoidable, especially for the patients with retinal breaks or retinal detachment.

    Difficult to control atopic dermatitis (AD) presents a therapeutic challenge and often requires combinations of topical and systemic treatment. Anti-inflammatory treatment of severe AD most commonly includes topical glucocorticosteroids and topical calcineurin antagonists used for exacerbation management and more recently for proactive therapy in selected cases. Topical corticosteroids remain the mainstay of therapy, the topical calcineurin inhibitors tacrolimus and pimecrolimus are preferred in certain locations. Systemic anti-inflammatory treatment is an option for severe refractory cases. Microbial colonization and superinfection contribute to disease exacerbation and thus justify additional antimicrobial / antiseptic treatment. Systemic antihistamines (H1) may relieve pruritus but do not have sufficient effect on eczema. Adjuvant therapy includes UV irradiation preferably of UVA1 wavelength. "Eczema school" educational programs have been proven to be helpful. PMID:23663504

    Topical steroids are still used suboptimally, but remain the mainstay of atopic dermatitis treatment. Topical steroid phobia is rampant in many countries, a real advantage for the entry on the market of topical immunomodulators (TIMs), which inhibit both antigen specific and non-specific T cell activation in the skin, by blockade of gene transcription of proinflammatory cytokines such as IL2 and TNF alpha. Topical tacrolimus and pimecrolimus have the most advanced clinical development. Tacrolimus, already used orally in transplantation medicine, is already available in France since 2003 as a 0.03% ointment for children (Protopic, Fujisawa). Its introduction on the market has substantially changed prescription habits in atopic dermatitis. Recalcitrant adolescent and adult head and neck lesions are the major target, but the drug is is also widely used in children, with a good safety profile. The risk of herpes virus superinfections did not increase significantly in clinical trials but needs further monitoring. Long-term prescription will need a closer look at a still much debated increased skin cancer risk. The marked efficacy on thin skin sites and absence of atrophogenic properties of the drug balance its side effects at the first applications on inflamed skin (pruritus, burning sensation). Clinical studies using pimecrolimus (Elidel, Novartis), marketed as a 1% cream, show a satisfactorily efficacy profile in adults and children including infants. The drug is better tolerated and is already widely introduced on the international market since 2002 with a pediatric positioning, but is nor available yet in 2004 in France. Besides phototherapy, systemic immunosuppressants remain useful drugs in severe disease especially in older children and adolescents, cyclosporin remaining the leading drug. Preventive immunomodulation modifying the intestinal microflora is very promising approach which deserves a large-scale assessment. PMID:15808446

    Full Text Available Introduction: The precise nature of the previously described dermatitis herpetiformis bodies remains unknown.Aims: Our study was conducted to investigate the nature of dermatitis herpetiformis bodies in the skin in 7 cases of dermatitis herpetiformis, and to search for the presence of autoantibodies in other organsMethods: We utilized clinical, histopathologic, and immunologic methods to evaluate these patients.Results: Dermatitis herpetiformis bodies were found to be comprised of an amalgamation of immunoglobulins A and M, as well as molecules reactive with antibodies to armadillo repeat gene deleted in velo-cardio-facial syndrome, desmoplakins 1 and 2, and plakophilin 4. In addition, we found immunologic colocalization with selected autoantibodies associated with mitochondria in the skin, heart, kidney, and peripheral nerves. The dermatitis herpetiformis bodies did not demonstrate immunologic colocalization with tissue/epidermal transglutaminase.Conclusion: The complete biochemical nature of dermatitis herpetiformis bodies requires further characterization. Dermatitis herpetiformis bodies in these patients appear to be distinctly different than cytoid bodies. Further studies are required to determine if the antibodies to noncutaneous organs are pathogenic, and/or contribute to systemic morbility in dermatitis herpetiformis patients.

    Malassezia furfur is important in the pathogenesis of a number of dermatologic diseases including seborrheic dermatitis in adults. It has also recently been suggested that M. furfur might be the etiologic agent in infantile seborrheic dermatitis (ISD). We studied the presence of M. furfur in 21 children with the clinical diagnosis of infantile seborrheic dermatitis. Laboratory analyses showed aberrant patterns of essential fatty acids (EFA) in serum characterized by elevated levels of 18:1w9 and 20:2w6. Samples for M. furfur were taken from the foreheads and chests of children with infantile seborrheic dermatitis at the time of diagnosis, directly after treatment to complete healing, and after 1 year with no signs of infantile seborrheic dermatitis. All the patients were treated topically with borage oil containing 25% gammalinolenic acid (GLA). No reduced growth of M. furfur was seen on contact plates prepared with borage oil. The growth of M. furfur seems not to be related to the clinical symptoms in ISD. PMID:9436835

    Atopic dermatitis (AD) is a chronic, pruritic, inflammatory skin disease which predominantly affects children usually clearing up during or after childhood. However, AD may persist with a chronic recurrent course until adulthood, being recalcitrant to any treatment strategy. Moreover, in some patients AD is not present during childhood but starts later in life (i.e. after 16 years of age) being defined late-onset AD. Even if AD incidence is increasing worldwide with cases in which clinical manifestations first appeared or persisted during adolescence and adulthood raising, especially in industrialized countries, studies on adult AD are still scant. Since this subgroup of AD patients often has a nonflexural rash distribution, and atypical morphologic variants and validated diagnostic criteria are lacking, there is no clear consensus on the diagnostic work-up that should be performed when evaluating adult patients with AD. In this review the many aspects of work-up in adult patients with AD, such as diagnostic criteria, epidemiology, quality of life and pathogenesis are discussed. PMID:25658440

    2016-02-01

    Atopic dermatitis (AD) of the adult is a common skin disease. Its prevalence has greatly increased during the past decades. AD is commonly associated with other atopic disorders. Its impact on quality of life is often underestimated. Various immunopathologic mechanisms are involved in AD: innate epidermal barrier dysfunction due to filaggrin gene mutations, innate and adaptative abnormalities of the immune system (an initial Th2 phase precedes a chronic Th1 phase), intestinal and cutaneous microbiomes dysbiosis, and environmental factors. Diagnosis of AD is clinical and there is no predictive biomarker of future severity. The main differential diagnoses are: scabies, psoriasis, cutaneous adverse reaction, cutaneous T cell lymphoma, primary immunodeficiency, and Netherton's syndrome. Therapeutic management is challenging and should integrate a therapeutic education program. Topical corticosteroids are the first line treatment, including a preliminary assessment of possible topical corticosteroids phobia. Systemic treatments are recommended in severe, chronic and resistant AD, after careful evaluation in a reference centre. Dupilumab, an IL4/IL13 inhibitor, might be the first effective targeted therapy in AD, whereas therapies that specifically target the mechanisms of pruritus represent an exciting perspective.

    Cattle are considered to be the main reservoir for Shiga toxin-producing Escherichia coli (STEC) and are often the direct or indirect source of STEC outbreaks in humans. Accurate measurement of the concentration of shed STEC in cattle feces could be a key answer to questions concerning transmission of STEC, contamination sources and efficiency of treatments at farm level. Infected animals can be identified and the contamination level quantified by real-time quantitative PCR (qPCR), which has its specific limitations. Droplet digital PCR (ddPCR) has been proposed as a method to overcome many of the drawbacks of qPCR. This end-point amplification PCR is capable of absolute quantification independent from any reference material and is less prone to PCR inhibition than qPCR. In this study, the qPCR-based protocol described by Verstraete et al. (2014) for Shiga toxin genes stx1 and stx2 and the intimin gene eae quantification was optimized for ddPCR analysis. The properties of ddPCR and qPCR using two different mastermixes (EMM: TaqMan® Environmental Master Mix 2.0; UMM: TaqMan® Universal PCR Master Mix) were evaluated, using standard curves and both artificial and natural contaminated cattle fecal samples. In addition, the susceptibility of these assays to PCR-inhibitors was investigated. Evaluation of the standard curves and both artificial and natural contaminated cattle fecal samples suggested a very good agreement between qPCR using EMM and ddPCR. Furthermore, similar sensitivities and no PCR inhibition were recorded for both assays. On the other hand, qPCR using UMM was clearly prone to PCR inhibition. In conclusion, the ddPCR technique shows potential for the accurate absolute quantification of STEC on the farms, without relying on standardized reference material. PMID:27213452

The purpose of this review is to summarize the recent advances in occupational contact dermatitis as well as potential hazardous agents in the workplaces causing OCD. The review covers new developments in the epidemiology, etiology, diagnosis, and management of occupational contact dermatitis. This article also provides updated information on the prevalence of work-related skin symptoms and on new contact allergens among working population. It is emphasized that in the context of prevention of OCD, special attention should be focused on the identified high-risk occupational groups, especially healthcare workers and hairdressers starting with the apprentices. Current approaches include working out the standards and guidelines to improve the education, knowledge, diagnosis, and management of OCD based on a multidisciplinary team of medical specialists and an employer.

    Acute radiation dermatitis remains one of the most commonly observed side effect during radiation therapy leading to complication such as superinfection or treatment disruption. Its management is characterized by a great heterogeneity. Few strategies have demonstrated a benefit in preventing radiation dermatitis, which relies mostly on decreasing dose delivered to the skin and skin care practices. Simple emollients and use of topical steroids can be useful in early stages. The singularity of the skin toxicity seen with cetuximab and radiotherapy warrants a specific grading system and distinctive clinical treatment with use of antibiotics. (authors)

    Atopic dermatitis (AD) is an allergic skin disease, characterized by relapsing eczema, dry skin and chronic skin inflammation. A large proportion of AD patients develop other allergies or asthma later in life. Allergic contact dermatitis (ACD) in turn, is one of the leading occupational diseases worldwide. Therefore, allergic skin diseases not only impair the quality of life of patients but also cause a great economical burden for the society. This thesis investigates some of the mechanisms b...

    2013-01-01

    The history of contact dermatitis (CD) is inseparable from the history of the patch test, and the patch test is inseparable from the pioneer in the field, Josef Jadassohn (1860-1936). Despite the fact that we have been diagnosing, treating, and investigating the condition for more than 100 years, there are still many unsolved questions and controversies, which show no signs of coming to an end in the foreseeable future. This contribution reviews and highlights some of the disagreements and discrepancies associated with CD. For example: • What is the real sensitizer in balsam of Peru, one of the most common allergens, and what, if any, is the value of a low-balsam diet? • Is benzalkonium chloride, which has well-known and undisputed irritant properties, a contact allergen as well? • Is cocamidopropyl betaine (CABP) a common contact allergen and what is the actual sensitizer in CABP allergy the molecule itself, or impurities, or intermediaries in its synthesis? • How can the significant differences in the prevalence of sensitization of formaldehyde (FA, a common cause of contact allergy) between the United States (8%-9%) and Europe (2%-3%) be explained? • What is the relationship between formaldehyde releasers (FRs) allergy and an FA allergy? Should we recommend that FA-allergic patients also avoid FRs, and, if so, to what extent? • What is the true frequency of lanolin allergy? This issue remains enigmatic despite the expenditure of thousands of dollars and the innumerable hours spent investigating this subject. • What is the basis behind the so-called "lanolin paradox"? This label was coined in 1996 and is still a matter of controversy. • Is there such a thing as systemic CD from nickel, and, if so, to what extent? Is there a cross-reactivity or concomitant sensitization between nickel and cobalt?These are some of the controversial problems discussed. We have selected the ones that we consider to be of special interest and importance to the

  8. Use of textiles in atopic dermatitis: care of atopic dermatitis.

    Science.gov (United States)

    Ricci, G; Patrizi, A; Bellini, F; Medri, M

    2006-01-01

    Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease which usually starts during the first years of life. In the management of AD, the correct approach requires a combination of multiple treatments to identify and eliminate trigger factors, and to improve the alteration of the skin barrier. In this article we try to explain the importance of skin care in the management of AD in relation to the use of textiles: they may be useful to improve disrupted skin but they are also a possible cause of triggering or worsening the lesions. Garments are in direct contact with the skin all day long, and for this reason it is important to carefully choose suitable fabrics in atopic subjects who have disrupted skin. Owing to their hygienic properties fabrics produced from natural fibres are preferential. Wool fibres are frequently used in human clothes but are irritant in direct contact with the skin. Wool fibre has frequently been shown to be irritant to the skin of atopic patients, and for this reason wool intolerance was included as a minor criterion in the diagnostic criteria of AD by Hanifin and Rajka in 1980. Cotton is the most commonly used textile for patients with AD; it has wide acceptability as clothing material because of its natural abundance and inherent properties like good folding endurance, better conduction of heat, easy dyeability and excellent moisture absorption. Silk fabrics help to maintain the body temperature by reducing the excessive sweating and moisture loss that can worsen xerosis. However, the type of silk fabric generally used for clothes is not particularly useful in the care and dressing of children with AD since it reduces transpiration and may cause discomfort when in direct contact with the skin. A new type of silk fabric made of transpiring and slightly elastic woven silk is now commercially available (Microair Dermasilk) and may be used for the skin care of children with AD.

  18. Contact dermatitis to hair dye: An update

    Directory of Open Access Journals (Sweden)

    Sanjeev Handa

    2012-01-01

    Full Text Available Exposure to hair dyes has long been known as a significant risk factor for development of allergic contact dermatitis among the exposed population as these lead to severe eczema of face and upper trunk in the consumer and hand eczema in hair-dressers. Currently, para-phenylenediamine (PPD is the main ingredient used in permanent hair color products in the market and is the most important allergen. Prevalence of PPD sensitization is high in patients with contact dermatitis across all continents, with hair dye use being the commonest cause. In order to decrease the burden of disease, use of alternative natural dyeing agents among consumers and use of barrier neoprene gloves among hairdressers should be encouraged apart from stringent legislation to reduce the amount of PPD reaching the consumer.

    Guin, J D; Franks, H

    2001-04-01

    Prevalence of plant contact dermatitis in retail florists varies with exposure, and the number of reports of contact allergy to cut tulips is rather small. Alpha-methylene-gamma-butyrolactone is better known as the cause of both Alstroemeria dermatitis in retail florists and tulip finger in wholesale floral workers who handle the bulbs. Our patient presented with prominent erythema, scaling, and peeling of the skin of the thumb, index, and middle fingers of his right hand. Results of a patch test to alpha-methylene-gamma-butyrolactone were strongly positive, and the patient determined that the exposure had occurred when he stripped leaves from the tulip stems to arrange cut flowers. Other natural sources of the antigen include Alstroemeria; Bomarea; Dioscorea hispida; Erythronium; Gagea; Fritillaria; and at least one species of onion, Allium triquetrum. PMID:11324397

    Allergic contact dermatitis resulting from exposure to a chemical or chemicals is a common diagnosis in the dermatologist's office. We are exposed to hundreds of potential allergens daily. Patch testing is the criterion standard for diagnosing the causative allergens responsible for allergic contact dermatitis. Patch testing beyond standard trays is often needed to fully diagnose patients, but not all dermatology practices have access to this testing procedure or these allergens. In order to adequately evaluate patients, physicians must understand the pathophysiology of the disease process and be well versed in the proper evaluation of patients, indications for patch testing, proper testing procedure, and other diagnostic tools available and be aware of new and emerging allergens.

    Six men suffering from acute dermatitis had positive patch tests to Larrea (creosote bush). The lesions preferentially involved sun-exposed sites, simulating a photodermatitis, but also were on the legs and scrotum. Our findings were more consistent with contact allergy than with a primary irritant or a phototoxic response. The patch tests were also positive to Zuccagnia punctata. In two cases the exposure to the creosote bush occurred as a result of casual occupations, in two because of household remedies (moist compresses and baths), and in the other two as a result of burning the bush and resorting to household remedies. Attention should be drawn to this contact dermatitis because the creosote bush grows abundantly all over the American continent. PMID:3950120

    Diaper dermatitis is a common cutaneous condition characterized by an acute inflammatory eruption of the skin in the diaper area of an infant. Although this condition is relatively common, it can cause considerable pain and stress for infants and can be troublesome for their caregivers. In the United States, the frequency of diaper dermatitis is substantial and accounts for a high number of visits to health care providers. The three most common types of diaper dermatitis are chafing dermatitis, irritant contact dermatitis and diaper candidiasis. This article reviews common causes, differential diagnosis, current prevention and treatment recommendations, nursing implications and practical tips for families to utilize while caring for their infants at home.

    Because of the widespread use of botanicals, it has become crucial for health professionals to improve their knowledge about safety problems. Several herbal medicines contain chemicals with allergenic properties responsible for contact dermatitis. Among these, one is Rosmarinus officinalis L. (rosemary), a plant used since ancient times in folk medicine; at the present time it is used worldwide as a spice and flavouring agent, as a preservative and for medicinal and cosmetic purposes. The present article aims to revise and summarise scientific literature reporting cases of contact dermatitis caused by the use of R. officinalis as a raw material or as herbal preparations. Published case reports were researched on the following databases and search engines: PUBMED, MEDLINE, EMBASE, Google Scholar, Scopus. The used keywords were: R. officinalis and rosemary each alone or combined with the words allergy, contact dermatitis, allergic contact dermatitis, sensitisation and occupational dermatitis. The published case reports show that both rosemary extracts and raw material can be responsible for allergic contact dermatitis. Two cases related to contact dermatitis caused by cross-reactivity between rosemary and thyme were also commented. The diterpene carnosol, a chemical constituent of this plant, has been imputed as a common cause for this reaction. The incidence of contact dermatitis caused by rosemary is not common, but it could be more frequent with respect to the supposed occurrence. It seems plausible that cases of contact dermatitis caused by rosemary are more frequent with respect to the supposed occurrence, because they could be misdiagnosed. For this reason, this possibility should be carefully considered in dermatitis differential diagnosis. PMID:23827646

    Full Text Available Context: Frictional lichenoid dermatitis. Background: Frictional lichenoid dermatitis (FLE is an entity that is probably under diagnosed and has been variably associated with either friction and/or atopy with a distinctive seasonal variation. Aims and Objectives : To study correlation of FLE with UV index and to assess its association with atopic dermatitis. Materials and Methods: A cross sectional analysis of children with FLE was done, over a period of 6 years in two tertiary hospitals. A detailed history and examination was done to assess the features of atopic dermatitis. The number of cases seen per month was compared with the mean monthly UV index. Two-tailed significance tests using Pearson′s coefficient of correlation and T-test were used to interpret the data. (P < 0.05. Results: One hundred seventy-four patients were studied using the UKC criterion 17.2% of the patients had AD while xerosis (40.3% was the predominant cutaneous finding. The number of patients seen in summer was more than in winter (P < 0.05 but there was no statistical difference between the cases in winter and spring. There was a significant correlation of the number of cases per month with UV index (P = 0.019. Almost 42% of patients gave a history of recurrence. Conclusions : FLE is probably not associated with atopic dermatitis and is likely to be related to the ambient UV index though a larger cohort with meticulous follow up may be needed to draw a final conclusion. Statistical Analysis Used: The Pearson′s coefficient of correlation was used for comparing the cases per month with the UV index. The tests of hypothesis used included the paired T-tests. F-test of variance, Welch test, Wilcoxon rank sum test and the Kolmogorov-Smirnov Test. P < 0.05 was considered significant.

    Atopic dermatitis is the most common chronic inflammatory disease among children in industrialised countries. Many factors influence this disease in a negative way and contact allergy is one such factor. The aim of the study was to examine the frequency of contact allergy among children with the diagnosis atopic dermatitis. Contact allergy was found in 22/82 children (26.8%), the most common from Amerchol L101 (11.0%), potassium dichromate (7.3%), and nickel sulfate (4.9%). A statistically significant difference in contact allergy frequency was demonstrated for those with hand and/or foot eczema compared to those without. Children with atopic dermatitis who suffer from hand and/or foot dermatitis should always be patch-tested to evaluate whether they have a relevant contact allergy and thus allergic contact dermatitis.

    Full Text Available Christina M Gelbard1, Adelaide A Hebert1,21Departments of Dermatology; 2Pediatrics, University of Texas-Houston, Houston, TX, USAAbstract: Atopic dermatitis is a chronic, inflammatory skin condition that affects 10% to 20% of children and 1% to 3% of adults in the US. Symptoms often result in sleeplessness, psychological stress, poor self-esteem, anxiety, and poor school or work performance. The cost of atopic dermatitis is estimated to be US$0.9 to 3.8 billion every year. Topical steroids are first-line treatment for atopic dermatitis, and recent advances in vehicle technologies have resulted in improved patient tolerability and compliance. Topical calcineurin inhibitors are also safe and effective topical treatments for atopic dermatitis, and provide an additional therapeutic option for patients with this disease. Systemic immunomodulators are used in the treatment of severe refractory disease. Cyclosporine, methotrexate, azathioprine, mycophenolate mofetil, and interferon gamma have been used in the management of severe atopic dermatitis. This review highlights the current and emerging trends in the treatment of atopic dermatitis.Keywords: atopic dermatitis, topical corticosteroids, calcineurin inhibitors, methotrexate, cyclosporine, mycophenolate mofetil, IFN-γ

    Full Text Available Background: The photopatch test is used to detect photoallergic reactions to various antigens such as sunscreens and drugs. Photosensitive dermatitis can be caused due to antigens like parthenium, fragrances, rubbers and metals. The photopatch test does not contain these antigens. Therefore, the Indian Standard Series (ISS along with the Standard photopatch series from Chemotechnique Diagnostics, Sweden was used to detect light induced antigens. Aim: To detect light induced antigens in patients with photosensitive dermatitis. Methods: This study was done in a descriptive, observer blinded manner. Photopatch test and ISS were applied in duplicate on the patient's back by the standard method. After 24 hours, readings were recorded according to ICDRG criteria. One side was closed and other side irradiated with 14 J/cm2 of UVA and a second set of readings were recorded after 48 hrs. Result: The highest positivity was obtained with parthenium, with 18 out of 35 (51% patients showing a positive patch test reaction with both photoallergic contact dermatitis and photoaggravation. Four patients (11% showed positive patch test reaction suggestive of contact dermatitis to potassium dichromate and fragrance mix. Six patients had contact dermatitis to numerous antigens such as nickel, cobalt, chinoform and para-phenylenediamine. None of these patients showed photoaggravation on patch testing. Conclusion: Parthenium was found to cause photoallergy, contact dermatitis with photoaggravation and contact allergy. Hence, photopatch test and UV irradiated patch test can be an important tool to detect light induced antigens in patients with photosensitive dermatitis.

    Full Text Available Emiliano Antiga, Marzia Caproni Department of Surgery and Translational Medicine, Section of Dermatology, University of Florence, Florence, Italy Abstract: Dermatitis herpetiformis (DH is an inflammatory cutaneous disease with a chronic relapsing course, pruritic polymorphic lesions, and typical histopathological and immunopathological findings. According to several evidences, DH is considered the specific cutaneous manifestation of celiac disease, and the most recent guidelines of celiac disease have stated that, in celiac patients with a proven DH, a duodenal biopsy is unnecessary for the diagnosis. In this review, the most recent data about the diagnosis and the management of DH have been reported and discussed. In particular, in patients with clinical and/or histopathological findings suggestive for DH, the finding of granular IgA deposits along the dermal–epidermal junction or at the papillary tips by direct immunofluorescence (DIF assay, together with positive results for anti-tissue transglutaminase antibody testing, allows the diagnosis. Thereafter, a gluten-free diet should be started in association with drugs, such as dapsone, that are able to control the skin manifestations during the first phases of the diet. In conclusion, although DH is a rare autoimmune disease with specific immunopathological alterations at the skin level, its importance goes beyond the skin itself and may have a big impact on the general health status and the quality of life of the patients.

    2016-08-01

    Vitamin D influences allergen-induced pathways in the innate and adaptive immune system, and its potential immunomodulatory role in allergic skin disorders has been explored. This comprehensive review article provides an overview of the role of vitamin D in three common dermatologic conditions: atopic dermatitis (AD), chronic urticaria, and allergic contact dermatitis (ACD). Whereas the literature regarding vitamin D and AD has resulted in mixed findings, several studies have described an inverse relationship between vitamin D levels and AD severity, and improvement in AD with vitamin D supplementation. Similarly, several studies report an inverse relationship between vitamin D levels and severity of chronic urticaria. Although current research in humans remains limited, an increased likelihood of ACD has been demonstrated in vitamin D-deficient mice. Additional well-designed clinical trials will be necessary to determine whether vitamin D supplementation should be recommended for prevention or adjuvant treatment of these common dermatologic conditions.

    2002-10-01

    The majority of adverse effects of cosmetics have been attributed to soaps in Dutch and English studies, but to eye makeup in a recent Swedish study. The reactions may be caused by irritants or by sensitizing substances. The aim of the present study was to evaluate the irritation potential of commercially available mascaras. The mascaras were exposed to the skin in aluminium chambers. The skin reaction was evaluated using both visual assessments of erythema and non-invasive measurements of the skin reaction. Seven mascaras were tested on 15 healthy individuals in a randomized and blinded fashion. Two of the seven tested mascaras induced pronounced skin inflammation, when applied to normal skin under occlusion. These two mascaras were based on volatile petroleum distillate, in contrast to the other five mascaras that were conventional emulsions with stearate as the main emulsifier. The findings suggest that solvent-based mascaras might induce contact dermatitis due to its content of irritating substances. PMID:18498521

    Rosacea is a common, chronic cutaneous disorder with a prevalence of 0.5-10%, predominantly affecting women. The disease presents with a heterogeneous clinical picture characterized by transient flushing, persistent facial redness, telangiectasias, and, in more severe clinical forms, the presence of inflammatory papules and pustules in the central third of the face. Although its pathophysiology is complex and still remains unknown, factors that exacerbate the disease are well defined. They include genetic predisposition as well as external factors such as exposure to UV light, high temperature, and diet. Besides these well-known factors, recent studies suggest that drugs and vitamins could also be possible factors inducing rosacea-like dermatitis or aggravating pre-existing rosacea. Although these are less common possible triggering factors, the aim of this article is to present the current knowledge on the association between use of certain drugs or vitamins and rosacea.

    2010-12-01

    Allergic contact dermatitis (ACD) is a common skin disease that has significant socio-economic impact. ACD is mediated by a T-cell mediated inflammatory reaction. Langerhans cells (LCs) are an epidermal DCs subset specialized in antigen presentation. After hapten exposure, LCs play a major role as in induction adaptive immune response against allergens. LCs recognize, take up and process haptens and migrate to the local draining lymph nodes. However, LCs specific functions and the LCs migration to local draining lymph nodes are not yet clearly defined. Recent advance in the knowledge of LCs function has increased in the past decades including the evidence for a tolerogenic function of LCs. The present review will focus on the role for LCs response to contact allergens. PMID:21139551

    2011-07-01

    Atopic dermatitis (AD) is a common, chronic or chronically relapsing, severely pruritic, eczematous skin disease. AD is the second most frequently observed skin disease in dermatology clinics in Japan. Prevalence of childhood AD is 12-13% in mainland Japan; however, it is only half that (about 6%) in children from Ishigaki Island, Okinawa. Topical steroids and tacrolimus are the mainstay of treatment. However, the adverse effects and emotional fear of long-term use of topical steroids have induced a "topical steroid phobia" in patients throughout the world. Undertreatment can exacerbate facial/periocular lesions and lead to the development of atopic cataract and retinal detachment due to repeated scratching/rubbing/patting. Overcoming topical steroid phobia is a key issue for the successful treatment of AD through education, understanding and cooperation of patients and their guardians. PMID:22053299

    Cercarial dermatitis (swimmer's itch) is a worldwide, often neglected parasitic skin disease characterized by strong maculopapular skin eruption accompanied by intensive itching. A fisherman suffered from forearm dermatitis. Clinical history associated with the recovery of the avian schistosome; Gigantobilharzia from little green bee-eater (Merops orientalis najdanus) and collected Lymnaea snails supported the authors' opinion that patient clinical signs are most likely due to the invasion of avian schistosome cercariae.

    Ancylostomum caninum larvae cause damage to the host at the point of entry through the skin leaving a wound vulnerable to secondary infections. As the larvae migrate through the skin an inflammatory response, dermatitis, is often stimulated which can be exacerbated in hosts which give hypersensitive responses. We assessed a 44-year-old man with contact dermatitis diagnosed as nickel allergy but caused by Ancylostoma caninum infection. PMID:26342510

    Skin and skin adnexa toxicities are the most common side effects associated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) and occur in most patients receiving this therapy. The majority of these cutaneous side effects are transient, reversible, and dose dependent. Although these symptoms are in general not severe, they significantly affect quality of life and can have a serious effect on treatment compliance as well as the treatment regimen. The most common early symptoms present as papulopustules on an erythematous base, usually localized in seborrheic areas. This clinical presentation is commonly described as "acneiform", although these adverse reactions have clinical presentations, such as rosacea-like and seborrheic-like dermatitis. In this context, we report a case of a 77-year-old man with a medical history of planocellular lung cancer with ipsilateral pulmonary metastasis and mediastinum infiltration who received erlotinib as a third-line therapy, presenting with centrofacial rosaceiform rash as a side effect associated with the use of EGFR-TKIs. The patient had a negative previous history of rosacea. Therefore, symptoms probably occurred as an adverse reaction due to the oncological therapy. Current terminology of early cutaneous adverse reactions caused by EGFR-TKIs refers to "acneiform" or "papulopustular" lesions, excluding less common side effects such as rosacea-like dermatitis so these symptoms might be overlooked and misdiagnosed. Thus, we would like to emphasize the importance of developing a more accurate classification of terms in order to provide early detection of all possible cutaneous side effects, including less common ones, providing specific and timely treatment, and allowing continuation of drug therapy.

    Full Text Available Irritant contact dermatitis (ICD is responsible for the vast majority of occupational contact dermatitis and usually seen in professional groups working with wet hand. However, today, with the increasing business lines, employees are exposed to a variety of irritants. Occupational exposure to many chemicals and toxic irritants affect not only the skin, but also the other systems. Therefore, this situation resulting with loss of work and changes in business may become a public health problem. The diagnosis of occupational contact dermatitis should not be limited only with tests for allergens, detailed history of exposure to workplace substances and careful examination of product safety forms are necessary. In addition, by establishing close relationship between occupational physicians and employers, preventive measures should be taken before similar diseases occur in other workers in the same work place. In order to highlight this issue, a 32-year-old male patient working in an invitation card fabric is presented in this case report. Irritant contact dermatitis secondary to “petroleum naphta” was present in the patient’s arms. Another important feature of this case, as far as we know, this is the first case of irritant contact dermatitis due to naphtha in the literature.

    Full Text Available Background: Although acute radiation dermatitis (ARD is a common side-effect of radiotherapy (RT, currently there is no general consensus about its prevention or treatment of choice. Aims: The purpose of this study was to investigate whether prophylactic use of topical betamethasone 0.1% can prevent ARD caused by chest wall irradiation. Methods: Fifty-one patients who underwent modified radical mastectomy for breast cancer and were going to receive RT, were randomly assigned to receive topical betamethasone 0.1%, petrolatum or none during RT. The frequency and severity of ARD (measured using Radiation Therapy Oncology Group acute radiation morbidity scoring criteria were recorded at the end of each week during RT and two weeks after its completion. Clinical outcomes were analyzed by relevant statistical methods. Results: All patients developed some degree of ARD, the frequency and severity of which increased with time and reached the maximum at the end of the seventh week for all groups. Patients receiving betamethasone had less severe ARD than the other two groups throughout the course of the study, but this difference was significant only at the end of the third week (p =0.027. No significant difference was observed between the petrolatum and control arms. Conclusion: Prophylactic and ongoing use of topical betamethasone 0.1% during chest wall RT for breast cancer delays occurrence of ARD but does not prevent it. Petrolatum has no effect on the prevention of ARD in these patients.

    2014-04-01

    Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction. During the last decade, there has been a heightened awareness of this disease in the pediatric population. The gold standard for diagnosis is patch testing. The prevalence of positive patch tests in referred children with suspected ACD ranges from 27 to 95.6 %. The most common allergens in children in North America are nickel, neomycin, cobalt, fragrance, Myroxylon pereirae, gold, formaldehyde, lanolin/wool alcohols, thimerosal, and potassium dichromate. The relationship between ACD and atopic dermatitis (AD) is complicated with conflicting reports of prevalence in the literature; however, in a patient with dermatitis not responding to traditional therapies, or with new areas of involvement, ACD should be considered as part of the work-up.

Although topical corticosteroids have been the mainstay of treatment, alternative therapies are often needed to avoid protracted use of topical corticosteroid therapy in order to avert side effects and to sustain control of the disorder. Topical pimecrolimus, a calcinuerin inhibitor, is a safe alternative for seborrheic dermatitis and is more ideal for long-term use. More specifically, topical pimecrolimus not only has an attractive safety profile with no risk of many of the potential side effects seen with topical corticosteroids, but also has favorable efficacy data, including more data on long-term use.

    Childhood-onset dermatitis is one of the most common skin disorders in children. Although various mouse models that mirror aspects of dermatitis have become available, there is still a need for an animal model that develops dermatitis in childhood and is more suitable for performing tissue transplantation experiments. There is emerging evidence that peripheral blood T lymphocytes from patients with dermatitis have significantly increased telomerase activity. Here, we developed telomerase reverse transcriptase (TERT)-expressing transgenic (Tg) rats that spontaneously developed eczematous skin inflammation in childhood. Newborn TERT-Tg rats developed visible dermatitis in 56 % of cases, and the skin lesions microscopically showed spongiosis and acanthosis with infiltration of lymphocytes, eosinophils and mast cells. TERT-Tg rats with dermatitis exhibited increased CD4 (2.5-fold) and CD8 (fivefold) T cell numbers compared with dermatitis-free TERT-Tg rats. Stronger TERT activity was observed in the peripheral lymphocytes of dermatitis-positive TERT-Tg rats than those of dermatitis-free TERT-Tg rats. RT-PCR analysis revealed that IL-4 was markedly elevated in the spleen of dermatitis-positive TERT-Tg rats, and that interferon-gamma was increased in the dermatitis lesions. Moreover, skin grafting of TERT-Tg rats with dermatitis onto T cell-deficient nude rats demonstrated that the inflamed skin lesions could not be maintained. Taken together, the results suggest that TERT activation in T lymphocytes is one of the potential predisposing factors for dermatitis. Moreover, our results demonstrated that the TERT-Tg rats mirror aspects of human childhood-onset dermatitis and that these animals represent a potential animal model system for studying childhood-onset dermatitis.

    2013-05-01

    The effects of scalp dermatitis (seborrheic dermatitis (SD), psoriasis, and atopic dermatitis (AD)) on chemical properties of hair keratin were investigated by Fourier transform infrared (FT-IR) spectroscopy. Hairs were collected from lesional regions affected by SD, psoriasis, and AD and non-lesional regions separately. The hairs with SD were taken from patients with ages of 16-80 years. The ages of patients with psoriasis ranged from 8 to 67 years, and all patients exhibited moderate disease. Hairs with AD were taken from the patients with ages of 24-45 years and the average SCORing atopic dermatitis (SCORAD) was 48.75. Hairs from 20 normal adults were collected as a control. The FT-IR absorbance bands were analyzed by the Gaussian model to obtain the center frequency, half width, height, and area of each band. The height and area of all bands in the spectra were normalized to the amide I centered at 1652 cm-1 to quantitatively analyze the chemical composition of keratin. The spectra of hair with scalp dermatitis were different with that of control, the amide A components centered at 3278 cm-1 were smaller than those of the control. The psoriasis hair showed a large difference in the IR absorbance band between lesional and non-lesional hairs indicating good agreement with the morphological changes. The hairs with diseases did not show differences in the content of cystine, which was centered at 1054 cm-1, from the control. The chemical properties of keratin were not significantly different between the hairs affected by SD, psoriasis, and AD. However, the changes induced by scalp dermatitis were different with weathering. Therefore, FT-IR analysis could be used to screen differences between the physiological and pathological conditions of scalp hair.

Results : The proportion of footwear dermatitis was 24.22% (n=155 among a total of 640 patients patch tested during that period. Females [61.93% (n=96] were commonly affected than males [38.06% (n=59]. The ages ranged from 8 to 75 years. The age group that predominantly involved was the fifth decade [24.52% (n=38]. Occupationwise housewives were most commonly involved [47.48 (n=66]. Contributory allergens in order of frequency were: potassium dichromate, 45.8% (n=71; cobalt chloride, 38.06% (n=59; paraphenylenediamine, 32.25% (n=50; epoxy resin, 20% (n=31; black rubber mix, 20% (n=31; nickel sulfate, 14.83% (n=23; mercaptobenzothiazole, 12.9% (n=20; colophony, 11.6% (n=18; thiuram mix, 10.32 % (n=16; p-tert-butyl-formaldehyde resin, 9.67% (n=15; and formaldehyde, 4.5% (n=7. Among the different categories of footwear allergens, the highest positivity was shown by leather and leather-related chemicals in 61.9% cases (n=96. Conclusion : Footwear dermatitis, a common dermatosis, is mostly caused by leather processing chemicals, metal buckles, black dyes of shoes and socks, adhesives, plastic, rubber shoes and polishing agents in order of frequency.

  10. Contact sensitization to common haptens is associated with atopic dermatitis: new insight

    Introduction: It has been much debated whether atopic dermatitis is associated with contact sensitization since past findings have conflicted. A positive association might change our clinical practice. Objective: To investigate the association between atopic dermatitis and contact sensitization...... self-reported atopic dermatitis from this study mainly suffered from mild disease. However, clinicians should be aware of increased levels of contact sensitization in individuals with atopic dermatitis. Patch testing should therefore be considered at an early point in individuals with a history of...... atopic dermatitis and active disease. The fundamental relationship between atopic disease and environmental chemical exposure may be of a more complex and intimate nature than previously supposed....

    Temporary tattoos are widely applied today all over the world. The tattoo makers explain that they use "natural henna paint," although in fact they use "black henna," which includes a mixture of many substances, among them p-phenylenediamine (PPD). There have recently been many reports of allergic contact dermatitis because of temporary tattoo with PPD sensitization. We are adding a new case of temporary tattoo with black henna with an extensive reaction, in which a 12-year-old white boy showed contact dermatitis from PPD, followed by cutaneous eruption after corticosteroid topical treatment.

    Seborrheic dermatitis is a chronic recurrent inflammatory disorder presumed to be caused by increased sebaceous gland secretion, metabolic changes in the cutaneous microflora, and changes in the host immune function. Stellate ganglion block (SGB) is known to increase the blood flow rate without altering the blood pressure, heart rate, or cardiac output, to stabilize hypertonic conditions of the sympathetic nerves, and to affect the endocrine and immune systems. It is used in the differential diagnosis and treatment of autonomic nervous system disorders of the head, neck, and upper limbs. The authors report the first case of successful treatment of a patient with seborrheic dermatitis through repeated SGB trials. PMID:27064785

    Psychopathology in patients with DCM is as complex as its clinical forms where the factors are numerous and often intricate. It combines psychophysiological, psychopathological factors, behavioral disorders which can be the cause or the consequence of DCM but also the negative impact on quality of life and the simplest daily activities. DCM affects the quality of life of every patient, regardless of the severity. Women are more affected by the DCM that man older age, male sex, atopy and the existence of a contact sensitization are independent risk factors of severity. Depression may affect up to 10 % of patients, should involve greater attention from dermatologists and general practitioners. Health authorities and all health actors should be aware of interactions between secondary cognitive troubles or inherent to DCM and efforts required in terms of preventive measures. Thus, the presence of psychiatric comorbidity is more common in patients with chronic dermatoses. Today it is considered that the emotional environment, built by the mother - child relationship must be optimal, otherwise the mental stability of body image may be compromised. Diminished self-esteem, affects less well managed and somatic expression of emotional content. Recently, a surprising study showed that most patients with refractory occupational dermatitis were not able to recognize the warning sign of flare or the role of psychological factors in the formation and maintenance of the dermatose. In fact, they rejected their personal responsibility in the occurrence of the new flare. To address this public health problem, health authorities, trainers and caregivers should be aware of the cognitive impact of DCM in these patients and interactions with current means of prevention. The role of obsessive-compulsive washing as part of an anxiety disorder or personality disorder is most likely a contributing or maintaining factor systematically underestimated in the pathogenesis of DCM and in the

    Nucleolus is the most prominent subnuclear structure, which performs a wide variety of functions in the eu-karyotic cellular processes. In order to understand the structural and functional role of the nucleoli in bovine cells,we analyzed the proteomie composition of the bovine nueleoli. The nucleoli were isolated from Madin Darby bo-vine kidney cells and subjected to proteomie analysis by LC-MS/MS after fractionation by SDS-PAGE and strongcation exchange chromatography. Analysis of the data using the Mascot database search and the GPM databasesearch identified 311 proteins in the bovine nucleoli, which contained 22 proteins previously not identified in theproteomic analysis of human nucleoli. Analysis of the identified proteins using the GoMiner software suggestedthat the bovine nueleoli contained proteins involved in ribosomal biogenesis, cell cycle control, transcriptional,translational and post-translational regulation, transport, and structural organization.

    It is only by recognizing what we know that we know, and being cognizant of the things that we know that we don't know that clinicians and the health profession are able to deliver quality care to patients. Traditional learning methods can sometimes perpetuate unappraised and unfounded beliefs and practices. Evidence-based practice requires robustly conducted systematic reviews and evidence-based guidelines. There have only been three systematic reviews of occupational contact dermatitis. These inform us of what we know we know and what we know that we don't know. We know which agents cause allergic and irritant occupational contact dermatitis, and we know the occupations that present the greatest risk. We know that conditioning creams are helpful in the prevention and management of the disease, and we know that we don't know the optimal frequency of application. We know that prework creams are not universally effective. We know that avoidance of exposure can help to improve symptoms in those who have developed dermatitis, but we know that we don't know if earlier identification and earlier avoidance of exposure produces better outcomes. Most importantly, we know that there is a need for better research conducted in occupational rather than experimental settings and with contact dermatitis rather than subclinical findings as an outcome measure.

Materials and Methods: The diagnostichypoallergenic diet was recommended for the period of 3 weeks. Severity of eczema was scored in agreement with SCORAD score, and especially the intensity criteria (erythema, edema, crusting, excoriations, lichenifications, dryness and subjective parameters (pruritus, sleeplessness were evaluated at the beginning and at the end of this diet. Results: One hundred and forty-eight patients suffering from atopic dermatitis were included in the study: 107 women and 41 men with the average age of 26.03 (s.d. 9.6 years, min. 14 max. 63 years. In the end of 3 weeks diagnostic hypoallergenic diet there was a statistically significant reduction in severity of sleepless and pruritus and in all of the intensity criteria except of lichenification. Conclusion: The diagnostic hypoallergenic diet can improve the intensity criteria and subjective parameters of atopic dermatitis evaluated in SCORAD, but not the lichenification. We recommend to introduce this diet before a challenge tests and as a temporary medical arrangement in patients suffering from moderate or severe form of atopic dermatitis.

    2012-07-01

    Colloidal oatmeal has been used for decades to soothe and ameliorate atopic dermatitis and other pruritic and/or xerotic dermatoses. In-vitro and/or in-vivo studies have confirmed the anti-inflammatory, barrier repair, and moisturizing properties of this compound. A broad set of studies has been conducted in recent years to assess the effects of colloidal oatmeal as adjunct treatment in the management of atopic dermatitis (AD). This paper will review these studies. In these investigations, patients in all age groups (3 months to 60 years) with mild to moderate atopic dermatitis were included and allowed to continue their prescribed topical medications. These studies found that the daily use of moisturizers and/or cleansers containing colloidal oatmeal significantly improved many clinical outcomes of atopic dermatitis from baseline: investigator's assessment (IGA), eczema area and severity index (EASI), itch, dryness, and quality of life indices. Safety results showed that the formulations were well tolerated in babies, children, and adults with AD. PMID:22777219

    Seborrheic dermatitis is a chronic from of inflammatory dermatitis characterized by erythema and desquamation with predominant localization on the face (nasolabial folds, eyebrows, hair-line and ears). It appears to be caused by proliferation of Malassezia yeasts. Lithium gluconate 8% gel (Lithioderm 8% gel) is the only drug containing topical lithium salt commercially available in France for the treatment of seborrheic dermatitis. The mechanism of action of topical lithium is not well known; it may act through anti-inflammatory and antifungal action. Efficacy and safety were assessed in 2 clinical studies, one versus placebo and the other versus ketoconazole 2% foaming gel using the same principal criterion defined as the rate of patients showing complete remission after 2 months of treatment (complete disappearance of both erythema and desquamation). Lithium gluconate 8% was significantly more effective than placebo and than ketoconazole 2% foaming gel and was well tolerated. Adverse events observed were cutaneous (burning sensation, erythema and pruritus), for the most part of mild severity. No cutaneous side effects contributed to those reported with the use of systemic lithium in psychiatric disorders were noted. Pharmacokinetic studies have shown that systemic absorption after topical application is low. Lithioderm 8% gel is applied twice daily over a recommended period of 2 months. It constitutes a new alternative in the treatment of facial seborrheic dermatitis, regardless of severity. PMID:17483754

    Canine atopic dermatitis is a common disease and is considered as an animal model of the human disease. Immunomodulation by helminths is reported in several species. The aim of this study was to determine whether nematodes have an immunomodulatory effect on atopic dermatitis in dogs. In the pilot study, 12 atopic dogs were infected with either embryonated eggs of Trichuris vulpis (500 and 2500 eggs in 3 dogs each) or L3 larvae of Uncinaria stenocephala (100, 500 and 2500 eggs in 2 dogs each), respectively, for 3 months. Pruritus was evaluated with visual analogue scales and clinical lesions with the canine atopic dermatitis extent and severity index (CADESI). Skin biopsies were obtained for histopathology at the beginning and end of the study. In the subsequent placebo-controlled, double-blinded, randomised study, 21 dogs received either 2500 embryonated T. vulpis eggs or placebo and were evaluated similarly. In addition, allergen-specific serum IgE concentrations were determined. All dogs in the pilot study improved in their lesion scores, most in their pruritus scores. The cutaneous inflammatory infiltrate did not change significantly. In the subsequent randomised study, there was no significant difference between placebo and Trichuris administration in regard to pruritus or CADESI. IgE concentrations also did not change significantly. Infection with T. vulpis did not significantly change clinical signs of canine atopic dermatitis. PMID:21621922

    Full Text Available Background. Research has confirmed the involvement of oxidative stress (OxS in allergic contact dermatitis whilst other inflammation-related biomarkers have been less studied. Objective. To evaluate systemic levels of selected inflammatory markers, OxS indices and adipokines as well as their associations in allergic contact dermatitis. Methods. In 40 patients, interleukin- (IL- 6, monocyte chemoattractant protein (MCP-1, and IL-10 levels were measured in sera with the Evidence Investigator Cytokine & Growth factors High-Sensitivity Array, total peroxide concentration (TPX and total antioxidant capacity (TAC by means of spectrophotometry, and the plasma concentrations of adiponectin and leptin by the quantitative sandwich enzyme immunoassay technique. Results. TNF-α level (P < 0.01 and TPX (P < 0.0001 were increased whilst IL-10 (P < 0.05 and TAC (P < 0.0001 were decreased in the patients as compared to controls. Correlation and multiple linear regression analysis identified both, TPX and TAC (inversely, as possible independent markers for evaluating allergic contact dermatitis. Adiponectin level in patients was increased (P < 0.0001, but neither adiponectin nor leptin correlated significantly with the biomarkers of inflammation or OxS. Conclusion. OxS parameters, especially TPX and OSI, reflect the degree of systemic inflammation associated with allergic contact dermatitis in the best way. The relation between OxS and adiponectin level warrants further studies.

    A two years retrospective analysis of patients diagnosed as contact allergic dermatitis with positive patch test attending the Dermatology clinic was performed. Of the 346 patients with a positive patch test, 14% had occupational dermatitis. This condition affected mainly young and inexperienced workers. An inverse relationship was seen between age and prevalence of occupational allergic dermatitis. Allergic hand dermatitis was the commonest presentation in occupational allergic dermatitis. This was followed by dermatitis of the exposed skin (face, neck, hands and forearms). The common sensitising agents identified were rubber chemicals and nickel. The two main groups at risk were factory workers and medical personnel. The common allergens found in factory workers were epoxy resin, pewter, nickel and rubber chemicals. Exposure dermatitis occurred in patients working in the pewter industry. Two thirds of medical personnel with hand dermatitis were allergic to rubber gloves. One year follow up after patch testing showed that 19% of patients still suffered from chronic dermatitis. Dermatitis improved in 34% of patients. Forty-seven percent were cured and stopped attending the clinic after patch testing and adequate counselling. PMID:10972018

    Background:Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching.Most patients have personal and/or family history of atopic diseases.Several criteria have been proposed for the diagnosis of AD.Although the clinical features of childhood AD have been widely studied,there has been less large-scale study on adult/adolescent AD.The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.Methods:A hospital-based study was performed.Forty-two dermatological centers participated in this study.Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study.Questionnaires were completed by both patients and investigators.The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.Results:A total of 2662 valid questionnaires were collected (1369 male and 1293 female).Of all 2662 patients,2062 (77.5%) patients had the disease after 12 years old,while only 600 (22.5%) patients had the disease before 12 years old,suggesting late-onset eczema/AD is common.Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months.One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases.One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE.Based on these clinical and laboratory features,we proposed Chinese criteria for adult/adolescent AD.Of all 2662 patients,60.3% were satisfied with our criteria,while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria,suggesting a good sensitivity of our criteria in adult/adolescent AD patients.Conclusion:Late-onset of eczema or AD is common

    Atopic dermatitis (AD) and allergic contact dermatitis (ACD) are common allergic and inflammatory skin diseases caused by a combination of eczema, scratching, pruritus, and cutaneous sensitization with allergens. This paper examines whether oleanolic acid acetate (OAA) modulates AD and ACD symptoms by using an existing AD model based on the repeated local exposure of mite extract (Dermatophagoides farinae extract, DFE) and 2,4-dinitrochlorobenzene to the ears of BALB/c mice. In addition, the paper uses a 2,4-dinitrofluorobenzene-sensitized local lymph node assay (LLNA) for the ACD model. The oral administration of OAA over a four-week period attenuated AD symptoms in terms of decreased skin lesions, epidermal thickness, the infiltration of immune cells (CD4{sup +} cells, eosinophils, and mast cells), and serum IgE, IgG2a, and histamine levels. The gene expression of Th1, Th2, Th17, and Th22 cytokines was reduced by OAA in the lymph node and ear tissue, and the LLNA verified that OAA suppressed ACD. The oral administration of OAA over a three-day period attenuated ACD symptoms in terms of ear thickness, lymphocyte proliferation, and serum IgG2a levels. The gene expression of Th1, Th2, and Th17 cytokines was reduced by OAA in the thymus and ear tissue. Finally, to define the underlying mechanism, this paper uses a TNF-α/IFN-γ-activated human keratinocyte (HaCaT) model. OAA inhibited the expression of cytokines and chemokines through the downregulation of NF-κB and MAPKs in HaCaT cells. Taken together, the results indicate that OAA inhibited AD and ACD symptoms, suggesting that OAA may be effective in treating allergic skin disorders. - Highlights: • OAA reduced both acute and chronic AD symptoms. • OAA had a controlling effect on the immune reaction for ACD. • The effect of OAA on allergic skin disorders was comparable to the cyclosporine A. • OAA might be a candidate for the treatment of allergic skin disorders.

    Full Text Available Pellagra is a niacin deficiency disorder characterized clinically by diarrhea, dermatitis, and dementia. However, few drugs also cause pellagroid dermatitis. Recently, we encountered two cases of pellagroid dermatitis; both were on second line of antituberculosis drugs. Case 1 was of multidrug-resistant pulmonary tuberculosis. Patient was on ethionamide since one year before developing pellagroid dermatitis. Case 2 was of central nervous system tuberculoma and was on second line of antitubercular drugs. This patient was on ethionamide and isoniazid (INH since six months before developing pellagroid dermatitis. This patient had previously taken first line of antituberculous therapy, inclusive of INH, for 1 year without any dermatitis. The skin lesions in both patients were symmetric hyperpigmented thickened plaques with prominent skin markings resembling lichen simplex chronicus. Nicotinamide 300 mg in three divided doses healed the lesions completely within 4 weeks and 3 weeks in first and second patient, respectively.

    Atopic dermatitis and allergic contact dermatitis are both common skin diseases having an immune pathogenesis. There has been considerable interest about their inter-relationships with regard to altered susceptibility. Recent investigations have shed new light on this important question, and in...... this article, we explore whether there is evidence that atopic dermatitis affects the risk of contact sensitization and allergic contact dermatitis. The use of topical products to treat xerotic and inflamed skin in atopic dermatitis often results in a higher prevalence of sensitization to, for example......, fragrances and other ingredients in emollients. Moreover, the prevalence of metal allergy seems to be increased, probably due to compromised chelation of the metals in the stratum corneum of patients with atopic dermatitis. However, conversely, the T-helper cell 2 bias that characterizes immune responses in...

    Purpose: For patients with anal canal and advanced rectal cancer, chemoradiation therapy is a curative modality or an important adjunct to surgery. Nearly all patients treated with chemoradiation experience some degree of radiation-induced dermatitis (RID). Prevention and effective treatment of RID, therefore, is of considerable clinical relevance. The present phase III randomized trial compared the efficacy of silver clear nylon dressing (SCND) with that of standard skin care for these patients. Methods and Materials: A total of 42 rectal or anal canal cancer patients were randomized to either a SCND or standard skin care group. SCND was applied from Day 1 of radiation therapy (RT) until 2 weeks after treatment completion. In the control arm, sulfadiazine cream was applied at the time of skin dermatitis. Printed digital photographs taken 2 weeks prior to, on the last day, and two weeks after the treatment completion were scored by 10 blinded readers, who used the common toxicity scoring system for skin dermatitis. Results: The radiation dose ranged from 50.4 to 59.4 Gy, and there were no differences between the 2 groups. On the last day of RT, when the most severe RID occurs, the mean dermatitis score was 2.53 (standard deviation [SD], 1.17) for the standard and 1.67 (SD, 1.2; P=.01) for the SCND arm. At 2 weeks after RT, the difference was 0.39 points in favor of SCND (P=.39). There was considerable intraclass correlation among the 10 observers. Conclusions: Silver clear nylon dressing is effective in reducing RID in patients with lower gastrointestinal cancer treated with combined chemotherapy and radiation treatment.

    2014-01-01

    BACKGROUND: The acidic pH of the skin plays a role in antimicrobial defense by regulating the bacterial skin flora and aspects of barrier. Filaggrin is a co-factor in maintaining a low skin pH because of its degradation into acidic amino acids. Accordingly, lack of filaggrin due to filaggrin...... mutations may influence skin pH. OBJECTIVE: We aimed to determine the epidermal pH in different groups stratified by filaggrin mutations and atopic dermatitis. Further, we investigated the changes in pH according to severity of mutational status among patients with dermatitis, irrespective of skin condition....... METHODS: pH was measured with a multiprobe system pH probe (PH 905), and the study population was composed of 67 individuals, who had all been genotyped for 3 filaggrin mutations (R501X, 2282del4, R2447X).

  2. Atopic dermatitis and vitamin D: facts and controversies.

    Science.gov (United States)

    Mesquita, Kleyton de Carvalho; Igreja, Ana Carolina de Souza Machado; Costa, Izelda Maria Carvalho

    2013-01-01

    Patients with atopic dermatitis have genetically determined risk factors that affect the barrier function of the skin and immune responses that interact with environmental factors. Clinically, this results in an intensely pruriginous and inflamed skin that allows the penetration of irritants and allergens and predisposes patients to colonization and infection by microorganisms. Among the various etiological factors responsible for the increased prevalence of atopic diseases over the past few decades, the role of vitamin D has been emphasized. As the pathogenesis of AD involves a complex interplay of epidermal barrier dysfunction and dysregulated immune response, and vitamin D is involved in both processes, it is reasonable to expect that vitamin D's status could be associated with atopic dermatitis' risk or severity. Such association is suggested by epidemiological and experimental data. In this review, we will discuss the evidence for and against this controversial relationship, emphasizing the possible etiopathogenic mechanisms involved. PMID:24474104

    Hypnosis is well known for its modulatory effects on immune and inflammatory processes, and it is a therapeutic option for certain diseases of such pathogenesis. The authors report treatment of an adult patient with extensive atopic dermatitis, who was only minimally responsive to conservative treatment. In a 15 session hypnotherapy the authors combined the use of direct, symptom-oriented suggestive techniques with hypnotic procedures to identify and modify comorbid psychological issues. To monitor the effect of the treatment, patient diaries (quality and quantity of sleep, intensity of pain and itch) and repeated psychometric tests were used. At the end of treatment there were improvements in all measured dimensions (itch, pain, insomnia, activity, anxiety and emotional state) both clinically and psychometrically. The authors conclude, that hypnosis can be an effective adjunctive therapy in atopic dermatitis, and in certain severe cases may constitute a salvage therapy. PMID:26929974

Conclusion: In present study, the prevalence of atopic dermatitis was comparable in diabetic children and the controls which may be due to difference between races and geographic areas and lack of support for an inverse relationship between the Th2-mediated atopy and th1-mediated autoimmune disorder. Further studies are needed to show the difference in serum IgE and cytokine profiles between the groups.

    Full Text Available Contact dermatitis is frequent skin pathology and eyelids are one of the more frequent locations of this pathology. The objective of the present work was to study the population distribution of periocular dermatitis, determine the allergens which most frequently indicate positive in patch tests and in provocative use tests, and analyse the clinical relevance of the positive tests.Patients with periocular dermatitis (N=93 underwent a thorough physical examination and a patch test with standard series. According to clinical suspicions, 76 patients underwent a patch test with specific series. Finally a provocative use test was done for 36 patients with suspected  products  that  the  patients  brought.  The  tests  were classified according their relevance.The most  frequently observed allergen in the  patch tests (with standard and specific series was nickel followed by mercury, and anti-glaucoma drops in the provocative use tests with patients products.Patients’ sex, age, occupation, clinical status, presence of associated periocular symptoms, and presence of atopic or seborrheic dermatitis and/or rosacea did not relate with relevance.We conclude that  a clinical diagnosis may not  always be made with patch tests with standard and specific series due to lack of relevance. It is important to do provocative use tests with the products suspected as allergens in those cases where patch tests with standard and specific series indicated positive for more than one allergen.

  3. Allopurinol gel mitigates radiation-induced mucositis and dermatitis

    International Nuclear Information System (INIS)

    It has not been verified whether allopurinol application is beneficial in decreasing the severity of radiation-induced oral mucositis and dermatitis. Rats were divided into 4 groups and received 15 Gy irradiation on the left whisker pad. Group 1 received only irradiation. Group 2 was maintained by applying allopurinol/carrageenan-mixed gel (allopurinol gel) continuously from 2 days before to 20 days after irradiation. Group 3 had allopurinol gel applied for 20 days after radiation. Group 4 was maintained by applying carrageenan gel continuously from 2 days before to 20 days after irradiation. The intra oral mucosal and acute skin reactions were assessed daily using mucositis and skin score systems. The escape thresholds for mechanical stimulation to the left whisker pad were measured daily. In addition, the irradiated tissues at the endpoint of this study were compared with naive tissue. Escape threshold in group 2 was significantly higher than that in group 1, and mucositis and skin scores were much improved compared with those of group 1. Concerning escape threshold, mucositis and skin scores in group 3 began to improve 10 days after irradiation. Group 4 showed severe symptoms of mucositis and dermatitis to the same extent as that observed in group 1. In the histopathological study, the tissues of group 1 showed severe inflammatory reactions, compared with those of group 2. These results suggest that allopurinol gel application can mitigate inflammation reactions associated with radiation-induced oral mucositis and dermatitis. (author)

  4. Effectiveness of topical steroids in the control of radiation dermatitis

    International Nuclear Information System (INIS)

    Radiation dermatitis often presents as a problem for patients and radiotherapists during treatment. Topical corticosteroids have been shown to have an anti-inflammatory effect in the treatment of many skin diseases and are commonly prescribed during a course of radiation treatment. A comparison of two different steroid creams, 1% hydrocortisone cream and 0.05% clobetasone butyrate (Eumovate), in a double blind trial was carried out in 54 patients undergoing radiation therapy for breast cancer. 'The cream' was administered when patients reached a given dose of 2000 rad (or earlier if required) whether a skin reaction was present or not. The aim of the trial was to evaluate the general effectiveness of steroids in controlling radiation dermatitis and whether one type of cream was superior to the other. The majority of patients using either cream derived benefit in its soothing effect. There was, however, a significant difference in the intensity of reactions seen, patients using clobetasone butyrate developed more severe radiation reactions despite both groups having similar radiation doses. The possibility of two differing populations having different responses to radiation is discussed as is the 'breakthrough phenomenon' described in the literature. It is concluded that neither cream should be used as first choice in the control of radiation dermatitis. (author)

  5. Approach to atopic dermatitis in children by the Family Physician

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available Atopic dermatitis (AD is a chronic and inflammatory disease that affects the skin of children in their early stages of life. Its aetiology remains little understood, but it is known that there is a dysfunction of the skin barrier, which facilitates the penetration of allergens/irritants into the epidermis, causing an inflammatory response with a predominance of Th2 response relative to Th1. The diagnosis is clinical and may be associated with previous and family medical history of atopies such as rhinitis and asthma. AD manifests itself through eczematous, pruritic injuries with the presence of erythema, papules, vesicles, and scales. The main differential diagnoses of AD are seborrheic dermatitis, contact dermatitis, psoriasis and scabies. The treatment is based on the education of patients and their families, plus the control of pruritus with antihistamines and of inflammation with corticosteroids or calcineurin inhibitors. Given the high prevalence and impact of AD on the quality of life of paediatric patients, early diagnosis and an individualized approach are paramount.

    Full Text Available Bovine tuberculosis is caused by the infection of Mycobacterium tuberculosis var. bovis (M. bovis. This species is one of Mycobacterium tuberculosis complex, can infect wide range of hosts: cattle and other domesticated animals, wild mammals and humans (zoonotic. M. bovis bacterium from infected hosts can be transmitted to other susceptible animals and humans through respiratory excretes and secretion materials. Humans can be infected with M. bovis by ingested M. bovis contaminated animal products, unpasteurised milk from tuberculosis cows or through respiratory route of contaminated aerosol. Bovine tuberculosis at the first stage does not show any clinical sign but as the disease progress in the next stage which may take several months or years, clinical signs may arise, suh as: fluctuative body temperature, anorexia, lost body weight, coughing, oedema of lymph nodes, increased respiratory frequencies. Pathological lesion of bovine tuberculosis is characterised by the formation of granulomas (tubercles, in which bacterial cells have been localised, most in lymph nodes and pulmonum, but can occur in other organs. The granulomas usually arise in small nodules or tubercles appear yellowish either caseus, caseo-calcareus or calcified. In Indonesia, bovine tuberculosis occurred in dairy cattle since 1905 through the imported dairy cows from Holland and Australian. It was unfortunate that until recently, there were not many research and surveilances of bovine tuberculosis conducted in this country, so the distribution of bovine tuberculosis is unknown. Early serological diagnosis can be done on live cattle by means of tuberculin tests under field conditions. Confirmation can be done by isolation and identification of excreted and secreted samples from the slaughter house. Antibiotic treatment and vaccination were uneffective, therefore the effective control of bovine tuberculosis is suggested by tuberculin tests and by slaughtering the selected

    Bovine besnoitiosis, caused by the apicomplexan protozoan parasite Besnoitia besnoiti, was diagnosed in an Irish dairy herd. This is the first diagnosis of besnoitiosis in Ireland or the UK and the most northerly European outbreak yet described. The diagnosis occurred following a farm investigation in June 2015 into an unusual dermatological problem that had been ongoing since 2010. On an annual basis, 1-2 per cent of cows in the herd exhibited clinical signs, including skin thickening, alopecia, weight loss and poor performance. Others displayed pyrexia, limb oedema, respiratory distress and reduced milk yield. Histopathological examination of skin revealed granulomatous and eosinophilic dermatitis, with characteristic intradermal protozoal cysts, consistent with cutaneous besnoitiosis. Follow-up serological testing and clinical examination of cattle (n=228) on the farm found that 68 per cent (144/212) were seropositive for B. besnoiti In addition, 51 per cent (117/228) had characteristic scleral conjunctival cysts and 68 per cent (134/198) had vulval cysts. Postmortem examination of a severely affected animal revealed typical gross and histopathological lesions of B. besnoiti infection. These results confirmed endemic infection with B. besnoiti The identification of this exotic disease highlights the importance of veterinary surveillance at both local and national level, particularly in relation to emerging diseases.

    2014-11-01

    Full Text Available Background Atopic dermatitis is the first manifestation of allergic disease in early life. Early interventions may prevent the development of allergy disease. Allergy trace cards have been used to identify the level of allergic risk, based on family atopy scores. Because environmental factors may also influence the development of atopic dermatitis, the usefulness of the allergy trace card needs to be reevaluated. Objective To compare the incidence of atopic dermatitis in infants aged 0-4 months with total family atopy scores of > 0 to those with scores of 0. Methods We conducted this cohort study from June 1, 2012 to December 31, 2012 at Sanglah Hospital, Denpasar. Family atopy score was tabulated from all pregnant woman in the Obstetric Outpatient Clinic and the Maternity Room. Subjects were divided into two groups based on their total family atopy score: those with scores > 0 and those with scores of 0. The appearance of atopic dermatitis symptoms in the infants were evaluated until they reached 4 months of age. The incidence of atopic dermatitis in two groups was compared using Chi-square test. Results The incidence of atopic dermatitis in this study was 10.9%. The group with total family atopy scores of 0 had a significantly higher incidence of atopic dermatitis than the group with scores > 0 (adjusted RR 22.5; 95%CI 8.8 to 57.0; P = 0.001. Conclusion The incidence of atopic dermatitis is higher in infants with total family atopy score > 0 and this group has a 22.5 times higher risk of atopic dermatitis compared to infants with total family atopy score of 0. Allergy trace cards are relevant in differentiating the risk of atopy with regards to development of atopic dermatitis. We suggest that family atopy scores be evaluated during antenatal care in order to limit the development of atopic dermatitis in infants. [Paediatr Indones. 2014;54:330-7.].

The patch test is at present a helpful test for demonstrating contact type of allergy that identifies the cause of allergic contact dermatitis. Aim: To study the common topical medicaments and cosmetics capable of producing contact dermatitis and value of patch testing in these situations. Materials and Methods: One hundred patients suspected of having contact sensitivity to topical medicaments and common cosmetics were subjected to patch testing with the finished commercial product being used by the patient and the antigens of the Indian Standard Series and Cosmetic series kit. Results: Positivity with patch test of 96.65% was observed in patients with contact dermatitis to topical medicaments, whereas 85% of the patients with cosmetic dermatitis were tested positive. Among the cases with contact dermatitis to topical medicaments, Neomycin was tested positive in more number of patients and among the patients with cosmetic dermatitis; Kum-Kum powder and Fairness cream were tested positive in more number of patients. Conclusion: It is well known that topical medicaments are known to produce contact dermatitis; the cosmetics that are claimed to be very safe by their manufacturers do not stay much behind in doing so.

Methods We evaluated 15 cases of psoriasis and 20 cases of seborrheic dermatitis of the scalp that had been clinicopathologically diagnosed. Skin biopsy sections stained with H&E were examined. Additional immunohistochemistry was performed, including Ki-67, keratin 10, caspase-5, and GLUT-1. Results On histopathological examination, mounds of parakeratosis with neutrophils, spongiform micropustules of Kogoj, and clubbed and evenly elongated rete ridges were significantly more frequently observed in psoriasis. Follicular plugging, shoulder parakeratosis and prominent lymphocytic exocytosis were significantly more common in seborrheic dermatitis. Moreover, significantly higher mitotic figures were observed in psoriatic lesions than in seborrheic dermatitis. Immunohistochemistry did not show any difference between psoriasis and seborrheic dermatitis. Conclusion Histopathological features favoring psoriasis include mounds of parakeratosis with neutrophils, spongiform micropustules of Kogoj, clubbed and evenly elongated rete ridges, and increased mitotic figures (≥6/high-powered field). Features indicating seborrheic dermatitis are follicular plugging, shoulder parakeratosis and prominent lymphocytic exocytosis. Immunohistochemistry was not helpful in differentiating psoriasis from seborrheic dermatitis. PMID:27489423

    International Nuclear Information System (INIS)

    Objective: To determine the prevalence of ACD in atopics in comparison to non-atopics in our community. Design: Cross sectional study. Place and Duration of Study: Departments of Dermatology, King Edward Medical College/Mayo Hospital, Lahore, from May 1998 to July 1999. Subjects and Methods: Two hundred and fifty patients, 34 with past or present atopic dermatitis (Group I), 88 with personal or familial atopy (Group II) and 128 non-atopic with contact dermatitis (Group III) were subjected to patch testing with European standard series. The results were interpreted according to International Contact Dermatitis Research Group guidelines. Results: Positive reactions were seen in 50%, 70.4% and 67.8% of patients in the respective groups (p>0.05). Conclusion: Our results suggest that atopics are equally affected with contact dermatitis as compared with non-atopics and recalcitrant cases of atopic dermatitis should be patch tested to find out aggravating factors.

    Full Text Available Background and Design: Atopic dermatitis is a chronic, inflammatory skin disease characterized by itchy skin lesions. Since adolescents are intensely interested in their physical appearance, chronic skin diseases in this period can adversely affect the development of self esteem. Atopic dermatitis is a skin disease that affects the appearance and there is an heightened attention to the body image in adolescence which is an important period of time in the development of self-esteem. Therefore, we aimed to investigate self-esteem and dermatological quality of life in adolescents with atopic dermatitis. Materials and Methods: Thirty-three patients with atopic dermatitis and 33 healthy controls were included in the study. The Piers-Harris Children’s Self-Concept Scale and the Children’s Dermatology Life Quality Index (CDLQI were used for determining self-esteem and quality of life. The Scoring of Atopic Dermatitis (SCORAD Index was used to assess the severity of atopic dermatitis. Results: It was found that patient group had lower self-esteem than healthy controls according to the Piers-Harris Children’s Self-Concept Scale. A statistically significant difference was observed in happiness/satisfaction and anxiety subscale scores between the patients and healthy controls while there was no significant difference between the other sub-scale scores. Mean value of dermatological quality of life in patients with atopic dermatitis was significantly lower than in healthy controls. A moderate negative correlation was found between self-esteem and CDLQI scores among adolescents with atopic dermatitis. Discussion: This study results have shown that self-esteem and dermatological quality of life were adversely affected in adolescents with atopic dermatitis irrespective of gender. These patients should be examined psychiatrically besides dermatological examination and treatment. We suggest that improvement will be observed in self-esteem and quality of

    Full Text Available Background: Preservatives present in cosmetics and other industrial products can cause allergic contact dermatitis. The aim of the study was to assess the frequency of allergy to selected preservatives in consecutive patients examined due to contact dermatitis in the Nofer Institute of Occupational Medicine, Łódź, and to establish whether individuals sensitized to formaldehyde react simultaneously to formaldehyde releasers. Material and Methods: A group of 405 patients (308 females and 97 males was examined in 2011–2013. In all participants patch tests with a series of 13 preservatives (paraben mix, formaldehyde, Quaternium 15, chloromethylisothiazolinone/methylisothiazolinone mix, methyldibromoglutaronitrile, diazolidinyl urea, imidazolidinyl urea, DMDM hydantoin, 2-bromo-2-nitropropane-1,3-diol, iodopropynyl butylcarbamate, benzalkonium chloride, sodium metabisulfite, produced by Chemotechnique Diagnostics, Sweden were performed. Results: Of the 405 patients 74 (including 52 females showed positive results of patch tests. Contact allergy to at least 1 preservative was noted in 47 (11.6% patients, including 34 (11% females and 13 (13.4% males. Methylisothiazolinone proved to be the most frequent sensitizer – 4.7% (5.2% females, 3.1% males while parabens, 2-bromo-2-nitropropane-1,3-diol and imidazolidinyl urea (0.2% were found to be the least frequent. Fourteen (3.4% participants, 10 women and 4 men, were allergic to formaldehyde and/or formaldehyde releasers. In 11 (78.6% of them monovalent hypersensitivity was observed. In 13 (3.2% of the examined group patients allergy to preservatives might have been of occupational origin. Conclusions: Preservatives, particularly isothiazolinones, are significant causal factors of allergic contact dermatitis, including occupational cases. Individuals sensitized to formaldehyde may react simultaneously to formaldehyde releasers, however, such reactions are relatively rare. Med Pr 2015;66(3:327–332

    Full Text Available Background: Allergic contact dermatitis is one of the important occupational hazards in construction workers and it often leads to poor quality of life of the workers with substantial financial loss. However, this is often a neglected entity. There are no past studies on the construction workers in Indian subcontinent. Objective: This pilot study has been done to assess the allergological profile among the workers engaged in construction of roads and bridges. Materials and Methods: The study was conducted among the workers working on construction of a bridge, flyover, and roads in West Bengal, India. Sixteen workers were selected on clinical suspicion. Ten were selected randomly and patch tested with Indian standard battery of patch test allergens. Analysis of reactions and relevance of positive test was assessed as per standard guidelines. Results: All the workers were men. Average age of workers was 24.8 years (range, 19-34 years. Dermatitis affected exposed parts in 93.75% and covered areas in 62.5%. Total positive test was 24 and relevant 11. Most common allergens were chromate (relevant allergy/RA: in 60% of patch tested workers, epoxy resin (RA: 30%, cobalt (RA: 20%, nickel (RA: 20%, thiuram mixture (RA: 10% and black rubber mix (RA: 10%. Two cases (20% had irritant contact dermatitis. Conclusion: The result indicated that chromate is the most frequent allergen among construction workers in this part of India. High frequency of involvement of the covered areas as well as the exposed areas highlighted the fact that the allergens had access to most body parts of the workers.

    1999-10-01

    Compositae airborne dermatitis is a well-recognized disorder characterized by erythematosquamous lesions and papules on light-exposed areas. The presence of positive patch test reactions and the absence of specific serum IgE suggest delayed-type hypersensitivity, the murine model of which is characterized by a Th1 cytokine production profile [high amounts of interferon (IFN)-gamma and interleukin (IL)-2; little or no IL-4 and IL-5]. The aim of this study was to evaluate the cytokine profile of T-cell lines and T-cell clones from peripheral blood in a 38-year-old non-atopic male woodcutter affected by seasonal airborne contact dermatitis. The patient showed positive patch test reactions to several Compositae extracts (Achillea millefolium, Chamomilla recutita, Tanacetum parthenium, T. vulgare) and sesquiterpene lactone mix. On prick testing with Compositae and other plants, serum-specific IgE levels and phototesting were negative or normal. Allergen-specific T-cell lines produced with Compositae extracts showed a good in vitro cell proliferation only to C. recutita extract. Serial cloning performed using the C. recutita-specific T-cell lines revealed an alphabeta+CD4+ phenotype with high amounts of IFN-gamma and IL-4 in T-cell clones. Thus, these cells expressed a preferential Th0 phenotype. These data suggest that in addition to IFN-gamma, other T-cell derived cytokines, such as IL-4, may play a part in the immunopathogenesis of contact dermatitis. PMID:10583117

    Digital printing is described as a tool to replace conventional printing machines completely. Still this goal was not reached until now with any of the digital printing technologies to be described in the paper. Productivity and costs are still the main parameters and are not really solved until now. Quality in digital printing is no problem anymore. Definition of digital printing is to transfer digital datas directly on the paper surface. This step can be carried out directly or with the use of an intermediate image carrier. Keywords in digital printing are: computer- to-press; erasable image carrier; image carrier with memory. Digital printing is also the logical development of the new digital area as it is pointed out in Nicholas Negropotes book 'Being Digital' and also the answer to networking and Internet technologies. Creating images text and color in one country and publishing the datas in another country or continent is the main advantage. Printing on demand another big advantage and last but not least personalization the last big advantage. Costs and being able to coop with this new world of prepress technology is the biggest disadvantage. Therefore the very optimistic growth rates for the next few years are really nonexistent. The development of complete new markets is too slow and the replacing of old markets is too small.

    Nummular eczema or dermatitis is an uncommon paediatric pathology. It is presented as red-purplish small papules and vesicles that join to form exudative circular patches and then to eczematous or lichenified patches with discoid shape. The lesions appear predominantly on the extensor surface of extremities, although they can appear in trunk, hands or feet. This pathology has a clinical diagnosis; only few cases require complementary test. The topical corticosteroids are the mainstay of the treatment, and the causal treatment whether an infectious trigger is found. The patients have chronic or recurrent evolution. We report two cases in children with the aim of spreading knowledge among pediatricians. PMID:27399024

    Full Text Available Background and Design: The allergens responsible for allergic contact dermatitis vary among countries and even between different geographical regions within the same country over time. It is of great importance to perform the patch test at certain intervals, to evaluate the results in different centers and to compare them afterwards. Our aim was to evaluate the patch test results in our patients with allergic contact dermatitis.Material and Method: The records of the patients with allergic contact dermatitis, who had been patch tested between May 1997 and March 2009, were analyzed retrospectively. The demographic features such as age and sex, localization of the contact dermatitis, and the patch test results were recorded. Results: Of the 775 patients, 581 (75.2% were females and 194 (25% males. Of all patients, 735 were patch tested with the European Standard Series, 318 - with both the European Standard Series and cosmetic series, and 40-with cosmetic series alone. Of the patients tested with the European Standard Series, 255 (34.7% had at least one positive reaction. The most frequent allergen in the European Standard Series was nickel sulfate (17.3%, followed by cobalt chloride (7.2%, potassium dichromate (3%, fragrance mix (2.9%, and p-phenylenediamine base (2.6%. Of the 358 patients tested with cosmetic series, 82 (22.9% had at least one positive reaction. The 5 most frequently observed cosmetic series allergens were octyl gallate (3.9%, thimerosal (2.2%, sorbitan sesquioleate (2%, Euxyl K 400 (2% and methyldibromo glutaronitrile (1.4%. Conclusion: Our study shows the contact allergen profile of our center over 12 years. The most common allergens and their frequency differ between centers in various cities in Turkey. Those geographical differences should be re-evaluated by further studies performed in the certain time period. The high frequency of reactions to octyl gallate is an important finding in patients suspected of cosmetic allergy

We are reporting two cases presenting as ABCD who showed positive patch tests with Xanthium strumarium while the patch tests with Parthenium hysterophorus were negative. It is therefore necessary to realise that every case of ABCD is not caused by Parthenium, and patch testing with Parthenium alone can lead to serious mistakes.

    Studies of the prevalence of atopic dermatitis (AD) have provided insights into associated environmental risk factors, demonstrating the complex interactions between the presence of filaggrin (FLG) gene defects and environment. Among other important findings is that elevated transepidermal water loss (TEWL) in newborns is a strong predictor of AD, regardless of FLG status. Recently recognized predictors of disease course and severity include onset of AD signs and symptoms before 12 months of age and the presence of an FLG mutation and concomitant immunoglobulin E sensitization early in life.

    Atopic dermatitis is considered an important risk factor for chronic hand dermatitis, which can be seen in children too. Pimecrolimus cream 1% is approved to treat atopic dermatitis in children aged 2 years or older. In adults, this drug has been used for some clinical indications other than atopic dermatitis, such as chronic hand dermatitis. Here, we describe an adverse drug reaction in a 2-year-old child affected with atopic dermatitis, who was treated with topical pimecrolimus in order to ameliorate her concomitant hand dermatitis. The use of topical pimecrolimus led to a previously undescribed hand pustular dermatosis, being consistent with a form of pustular leukocytoclastic vasculitis, which required the permanent discontinuation of topical pimecrolimus.

    2012-12-01

    Three samples of 250ml at home temperature of 20°C were obtained from whole, low fat and fat free bovine UHT milk. They were analysed by measuring both impedance spectra and dc conductivity in order to establish the relationship between samples related to fat content. An impedance measuring system was developed, which is based on digital oscilloscope, a current source and a FPGA. Data was measured by the oscilloscope in the frequency 1 kHz to 100 kHz. It was showed that there is approximately 7.9% difference in the conductivity between whole and low fat milk whereas 15.9% between low fat and free fat one. The change of fatness in the milk can be significantly sensed by both impedance spectra measurements and dc conductivity. This result might be useful for detecting fat content of milk in a very simple way and also may help the development of sensors for measuring milk quality, as for example the detection of mastitis.

  8. Digitized mammograms

    International Nuclear Information System (INIS)

    Two observers conducted a blind evaluation of 100 mammography files, including 47 malignant cases. Films were read both before and after image digitization at 50 μm and 100 μm with the FilmDRSII. Digitization permitted better analysis of the normal anatomic structures and moderately improved diagnostic sensitivity. Searches for microcalcifications before and after digitization at 100 μm and 50 μm showed better analysis of anatomic structures after digitization (especially for solitary microcalcifications). The diagnostic benefit, with discovery of clustered microcalcifications, was more limited (one case at 100 μm, nine cases at 50 μm). Recognition of microcalcifications was clearly improved in dense breasts, which can benefit from reinterpretation after digitization at 50 μm rather 100μm

    The cases of 76 patients with chronic radiation dermatitis resulting from low-dose ionizing radiation for benign disease were reviewed retrospectively for risk factors leading to the development of neoplasia. The patients were studied with respect to original hair color, eye color, sun reactive skin type, benign disease treated, area treated, age at treatment, and age at development of first skin cancer. Analysis of data showed 37% of patients had sun-reactive skin type I, 27% had type II, and 36% had type III. Types IV through VI were not represented. There appeared to be an overrepresentation of types I and II. Increased melanin pigmentation may therefore be either directly or indirectly protective against the development of skin cancers in patients who have received low-dose superficial ionizing radiation for benign disease. The sun-reactive skin type of patients with chronic radiation dermatitis may be used as a predictor of skin cancer risk when the total dose of ionizing radiation is not known.

  13. A STUDY ON CONTACT DERMATITIS TO HAIR DYE AND HENNA

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available P- Phenylenediamine is an oxidative chemical that is frequently used as a permanent hair-coloring agent. It is added to henna to increase the intensity and longevity of the tattoo and expedites its drying time. Henna itself is a greenish brown vegetable coloring made from the leaves of Lawsonia inermis and rarely causes allergic contact dermatitis. The addition of PPD causes the contact sensitization to black henna. Serious adverse skin reactions to permanent hair dyes and temporary black tattoos have been reported. As temporary tattoos have become fashionable among adolescents, the risk profile for p-phenylenediamine (PPD sensitization of the population has changed simultaneously with an increasing use of hair dyes in this age group. With increased popularity of body art such as body piercing and tattooing, an increase in temporary henna tattoos has also occurred. Although the appeal of non-permanence exists for henna tattoos, dermatologists have begun to see numerous cases of allergic contact dermatitis linked with a certain type of henna. We selected 50 patients using hair dye and henna for our study. Patch testing was done in all the patients using Indian standard series of antigens. Regarding to the side effects to hair dye and henna and itching was the commonest symptom seen in 16% patients, erythematous scaly plaques were seen in 10% patients, vesicular reactions were seen in 6% patients, angioneurotic oedema and contact urticaria was seen in 4% patients each and anaphylaxis and keloidal reaction was seen in 2% patients each.

    Full Text Available Background. Increasing use of cosmetics has contributed to a rise in the incidence of allergic contact dermatitis (ACD to cosmetics. It is estimated that 1–5.4% of the population is sensitized to a cosmetic ingredient. Patch testing helps to confirm the presence of an allergy and to identify the actual allergens which are chemical mixtures of various ingredients. Objectives. The aims of this study are to perform patch testing in suspected ACD to cosmetics and to identify the most common allergen and cosmetic product causing dermatitis. Methods. Fifty patients with suspected ACD to cosmetics were patch-tested with 38 antigens of the Indian Cosmetic Series and 12 antigens of the Indian Standard Series. Results. The majority (58% of patients belonged to the 21–40 years age group. The presence of ACD to cosmetics was confirmed in 38 (76% patients. Face creams (20%, hair dyes (14%, and soaps (12% were the most commonly implicated. The most common allergens identified were gallate mix (40%, cetrimide (28%, and thiomersal (20%. Out of a total of 2531 patches applied, positive reactions were obtained in 3.75%. Conclusion. Incidence of ACD to cosmetics was greater in females. Face creams and hair dyes were the most common cosmetic products implicated. The principal allergens were gallate mix, cetrimide, and thiomersal.

    Full Text Available OBJECTIVE: Atopic dermatitis (AD is a chronic inflammatory disease causing intense pruritus, and with typical clinical features. There are few epidemiological studies concerning AD in adults, as well as little information about its prognostic. The aim of this study was to evaluate the clinical and epidemiological course of adults with AD. METHODS: 80 patients aged above 18 years (mean age = 29 years were selected (30 males and 50 females and interviewed about hospitalization, systemic corticoid usage, age of AD onset, and personal and/or familial history of atopy. Disease severity was evaluated through the Scoring Atopic Dermatitis (SCORAD tool. Laboratory examination included IgE serum levels and eosinophil blood count. RESULTS: 71 out of 80 patients referred association with respiratory symptoms (18 had asthma, 17 had rhinitis, and 36 had both conditions; nine out of 80 patients denied any respiratory disease. AD patients were divided in mild (n = 25, moderate (n = 30, and severe (n = 25; 56% had one or more hospitalizations due to AD. A positive association was found between IgE serum levels, eosinophil blood count, and disease severity. CONCLUSION: Adult AD represents a clinical challenge that needs to be better characterized, since it can be misdiagnosed and interferes with the patient's social and personal life. The association of skin and respiratory atopic disease is frequent, and laboratory parameters such as circulating IgE levels and eosinophil blood count may be helpful to assess disease severity.

    2016-01-01

    The cercarial dermatitis is a zoonotic, summer, skin-disease, caused by a swimming larva (cercaria) of a schistosomatid trematode. This larva accidentally penetrates the skin of people in the water, causing an allergic reaction, which is not always reported in health centers, so it is difficult to determine its incidence. Cases have been registered worldwide, including Argentina, although the epidemiological studies were performed only in the Northern Hemisphere. In this survey the epidemiology of cercarial dermatitis was studied in three Patagonian lakes watering places, Pellegrini, Mari Menuco, and Puelo, where surveys were conducted during summers of 2012-2013 and 2013-2014. The risk factors were analyzed and grouped in "personal characteristics", "use of the recreational resource", and "prevention measures". At the Pellegrini Lake, the people's sensitivity included in "personal characteristics" was the only determining factor for the occurrence of this zoonosis, mean while in Mari Menuco Lake, the bathing time and distance from the coast, and the use of lotions would affect the occurrence of swimmer's itch. In Puelo Lake, no cases were recorded during the study period. PMID:26826989

    Full Text Available Abstract Topical antiseptics are commonly used in the management of minor wounds, burns, and infected skin. These agents are widely used by health professionals and are often self-prescribed by patients as they are easily available over-the-counter. This case illustrates a 73 year old man who presented with a non-healing wound on his right forearm for 4 weeks. The wound started from an insect bite and progressively enlarged with increasing pruritus and burning sensation. Clinically an ill-defined ulcer with surrounding erythema and erosion was noted. There was a yellow crust overlying the center of the ulcer and the periphery was scaly. Further inquiry revealed history of self treatment with a yellow solution to clean his wound for 3 weeks. Patient was provisionally diagnosed to have allergic contact dermatitis secondary to acriflavine. Topical acriflavine was stopped and the ulcer resolved after treatment with non-occlusive saline dressing. Skin patch test which is the gold standard for detection and confirmation of contact dermatitis showed a positive reaction (2+ to acriflavine. Acriflavine is widely used as a topical antiseptic agent in this part of the world. Hence, primary care physicians managing a large variety of poorly healing wounds should consider the possibility of contact allergy in recalcitrant cases, not responding to conventional treatment. Patient education is an important aspect of management as this would help curb the incidence of future contact allergies.

    The aim was to describe the relapsing pattern, sensitization and prognosis of atopic dermatitis (AD) in the first 6 yr in a population-based, prospective birth cohort. The DARC cohort includes 562 children with clinical examinations, specific-IgE and skin prick test at all follow-ups. All children were examined for the development of AD using Hanifin-Rajka criteria and for food hypersensitivity by oral challenges. Severity of AD was measured by objective SCORing Atopic Dermatitis (SCORAD). Point-prevalence of AD peaked at 18 months of age (10%) and decreased at 36 and 72 months to slightly below 7%. The 6-yr cumulative incidence was 22.8% and sensitization was found in 43% of children with AD. It was predominately sensitization to foods, however shifting toward inhalant allergens with age. Sensitization at >or=2 follow-ups affected severity, whereas short-term sensitization at one follow-up does not. Children with early, non-IgE mediated (intrinsic) AD outgrew more often their eczema; however if they develop persistent AD, they remain intrinsic. Early long-term sensitization worsens the prognosis, but 38% of all children have a debut later than 18 months of age. Boys had earlier onset of AD than girls. The large number of follow-ups gives a detailed picture of the relapsing pattern and shows that the relapses occur independently of time of onset. We could not establish any clear correlation between elimination diets and AD duration nor severity. PMID:19788539

    Full Text Available Introduction and objectives: coeliac disease (CD and its cutaneous manifestation, dermatitis herpetiformis are both (DH gluten-sensitive diseases. Metabolic bone disease is common among patients with CD, even in asymptomatic forms. Data are scarce about bone density in patients with dermatitis herpetiformis. The aim of our study was to compare bone mineral density (BMD of celiac and dermatitis herpetiformis patients. Methods: 34 coeliac patients, 53 with dermatitis herpetiformis and 42 healthy controls were studied. The mean age was 38.0 ± 12.1, 32.18 ± 14.95, 35.33 ± 10.41 years in CD, dermatitis herpetiformis, and healthy controls, respectively. Bone mineral density of the lumbar spine, the left femoral neck and radius were measured by dual-energy X-ray absorptiometry. Low bone density, osteopenia and osteoporosis were defined as a body mass density (BMD T-score between 0 and -1, between -1 and -2.5, and under -2.5, respectively. Results: at lumbar region, consisting of dominantly trabecular compartment, a decreased BMD was detected in 49 % (n = 26 patients with dermatitis herpetiformis, 62 % (n = 21 of CD patients, and 29 % (n = 12 of healthy controls, respectively. Lower BMD were measured at the lumbar region in dermatitis herpetiformis and CD compared to healthy subjects (0.993 ± 0.136 g/cm² and 0.880 ± 0.155 g/cm² vs. 1.056 ± 0.126 g/cm²; p < 0.01. Density of bones consisting of dominantly cortical compartment (femoral neck did not differ in dermatitis herpetiformis and healthy subjects. Conclusions: our results show that a low bone mass is also frequent among patients with dermatitis herpetiformis. Bone mineral content in these patients is significantly lower in those parts of the skeleton which contain more trabecular than cortical bone.

    Topical minoxidil, the only approved treatment for female pattern hair loss (FPHL), has been associated with scalp allergic contact dermatitis (ACD). We report the case of 2 female patients who developed ACD from minoxidil solution with severe telogen effluvium and psoriasiform scalp dermatitis. Scalp dermoscopy was useful to identify the psoriasiform vascular pattern, whereas patch testing made it possible to differentiate the cause of sensitization. In one case, minoxidil was the sole cause of scalp dermatitis, while in the other patient it was only the vehicle, thus permitting the patient to continue the treatment for FPHL. PMID:27172052

    Atopic dermatitis is the most common chronic inflammatory skin disease. Its pathogenesis combines barrier defects, immune dysregulation, and increased skin infections; however, the relative contribution of each of these components is yet to be determined. Uninvolved atopic dermatitis skin also displays broad immune and barrier abnormalities, which highlights a role for proactive treatment strategy. The residual disease genomic profile that accompanies clinical resolution provides further support for proactive treatment approaches. Although intrinsic and extrinsic atopic dermatitis subtypes share a common clinical phenotype, they show some important differences in their Th22/Th17 cytokine profile, which opens the door for personalized specific therapeutics for each disease category.

    Despite the political intention to limit nickel allergy and dermatitis in Europeans, nickel allergy remains frequent. There are several explanations for the persistence of nickel allergy and dermatitis, including the increasing use of mobile phones. Before regulation of nickel release from mobile...... phones, we showed that eight (19.5%) of 41 mobile phones marketed in Denmark between 2003 and 2007 released nickel in concentrations that may result in nickel allergy and dermatitis. In 2009, the EU Nickel Directive was revised to include nickel-releasing mobile phones....

  5. Incorporation of a Barrier Protection Cream in the Management of Chronic Hand Dermatitis

    Science.gov (United States)

    2014-01-01

    A commonly encountered skin disorder in outpatient dermatology practice is hand dermatitis. In a considerable subset of patients, hand dermatitis can be a major source of prolonged distress when a pattern of chronicity develops due to repeated exposure to a variety of potential etiological factors. Most of the etiological factors are exogenous in nature. Hand dermatitis is an equal opportunity disease that affects both genders and occurs in individuals from all ethnic and cultural backgrounds. It is important to note that the term hand dermatitis does not refer to one specific diagnostic entity. Rather, hand dermatitis refers to multiple patterns of clinical disease that can be induced by a variety of exogenous sources. Occupational exposures with inadequate hand protection may be an important cause of epidermal barrier disruption, and in some cases contact allergy may be the primary cause or contribute to chronic hand dermatitis. In certain individuals, endogenous sources, such as atopic skin, cutaneous allergy (eczematous pattern), or skin hypersensitivity (urticarial pattern), may innately create predisposition to the development of hand dermatitis. Hand dermatitis can become a chronic problem that is often difficult to manage effectively. As consistency with hand protection and avoidance of irritant and allergenic contactants are integral to the effective treatment of chronic hand dermatitis, there is a high dependence on consistent patient adherence. Regardless of the etiological factors causing chronic hand dermatitis, lack of consistent hand protection is often a major reason why therapeutic results are suboptimal in some cases as exposure to the causes of the hand dermatitis are not adequately prevented. Regular wearing of protective gloves is not always feasible depending on the occupation, and although topically applied skin barrier protectants may be helpful in some cases, scientific data are generally limited with many products.

    Jellyfish envenomation often causes an immediate painful vesiculopapular eruption. Less commonly it can cause a type IV allergic hypersensitivity that manifests with delayed or recurrent cutaneous lesions at the primary site or distant from the primary site. These secondary reactivations may be related to high antijellyfish immunoglobulin levels, intracutaneously sequestered antigen, or cross-reacting venom. Immunomodulators such as pimecrolimus and tacrolimus and topical and intralesional corticosteroid therapy decrease this recurrent dermatitis. We report a case of a 9-year-old girl with a recurrent jellyfish dermatitis lasting more than 1 year after the initial envenomation. The dermatitis finally resolved after treatment with tacrolimus and intralesional triamcinolone acetonide therapy. PMID:24495001

    Detergent enzymes may cause skin irritation and occasionally hypersensitivity reactions. The potential hazards of these enzymes have led some physicians to advise atopic dermatitis patients against the use of enzyme-enriched detergents. A three-phased randomised, double-blind, cross-over experiment...... statistical differences in any of the primary or secondary parameters comparing treatment and placebo periods. Our data therefore seem to exclude that atopic dermatitis may exacerbate during 1 month's exposure to enzyme-enriched detergents. Since no significant irritant capacity was detected in atopic...... dermatitis patients, it is unlikely that consumers with "normal skin" will experience any skin discomfort when enzyme-enriched detergents are used....

  8. Evaluation of bovine hemimandible morphology by means of elliptic Fourier descriptors.

    Parés-Casanova, Pere M

    2014-01-01

    The aim of this research was to compare size (area) and shape variations of bovine hemimandibles according to age. Digital photographs were obtained for 34 hemimandibles belonging to different European breeds of cattle. The specimens were classified according to age, as determined by molar eruption: b months ("young", M1 erupting, n = 8), 10 months ("immature", M2 erupting, n = 9) and over 24 months ("adult", M3 fully erupted, n = 17). Captured images were then digitally analysed based on elliptic Fourier descriptors, which mathematically characterise the area and shape. Hemimandibular areas only showed significant differences between the adults (2752.3 cm2 +/- 250.4) and young subjects (2373.8 cm2 +/- 300.2). The areas for each age group were not linked to linear shape modifications, which was the same for all age groups. So, bovine hemimandibular form change is mainly related to size changes. Shape variability is centred on the condylar ramus. PMID:25345078

    We view Digital Ecosystems to be the digital counterparts of biological ecosystems, which are considered to be robust, self-organising and scalable architectures that can automatically solve complex, dynamic problems. So, this work is concerned with the creation, investigation, and optimisation of Digital Ecosystems, exploiting the self-organising properties of biological ecosystems. First, we created the Digital Ecosystem, a novel optimisation technique inspired by biological ecosystems, where the optimisation works at two levels: a first optimisation, migration of agents which are distributed in a decentralised peer-to-peer network, operating continuously in time; this process feeds a second optimisation based on evolutionary computing that operates locally on single peers and is aimed at finding solutions to satisfy locally relevant constraints. We then investigated its self-organising aspects, starting with an extension to the definition of Physical Complexity to include evolving agent populations. Next, ...

    Digital radiography has been used in human medical imaging since the 1980s with recent and rapid acceptance into the veterinary profession. Using advanced image capture and computer technology, radiographic images are viewed on a computer monitor. This is advantageous because radiographic images can be adjusted using dedicated computer software to maximize diagnostic image quality. Digital images can be accessed at computer workstations throughout the hospital, instantly retrieved from computer archives, and transmitted via the internet for consultation or case referral. Digital radiographic data can also be incorporated into a hospital information system, making record keeping an entirely paperless process. Digital image acquisition is faster when compared to conventional screen-film radiography, improving workflow and patient throughput. Digital radiography greatly reduces the need for 'retake' radiographs because of wide latitude in exposure factors. Also eliminated are costs associated with radiographic film and x-ray film development. Computed radiography, charged coupled devices, and flat panel detectors are types of digital radiography systems currently available. PMID:16971994

    Full Text Available Kaposi’s varicelliform eruption is a widespread viral infection frequently caused by herpes simplex virus types 1 and 2, and less frequently Coxsackie A-16 and vaccinia virus superimposed on a pre-existing dermatosis. It is often associated with atopic dermatitis. The topical immunomodulator pimecrolimus have proven effective in managing atopic dermatitis. Reported adverse effects are infrequent; however, cutaneous infections are potential complications of its application. Kaposi’s varicelliform eruption is the most important problem in treating patients with atopic dermatitis with pimecrolimus. Even though the causative effect of this topical immunomodulator remains unclear, patients should be thought to recognise herpes simplex virus infection and stop application to prevent the spreading of the infection. Herein we report a child with atopic dermatitis who developed Kaposi’s varicelliform eruption during treatment with pimecrolimus because of its rare occurence

    Seborrheic dermatitis is a common, chronic, relapsing inflammatory skin disorder that manifests as erythema, scaling and pruritus in sebum gland-rich areas of the skin. The objective of this article is to evaluate the clinical efficacy of pimecrolimus 1% cream in the treatment of seborrheic dermatitis compared with corticosteroids, antimycotics, placebo or no intervention. Pimecrolimus 1% cream appears to be a well-tolerated and effective treatment for seborrheic dermatitis. It has comparable efficacy, in terms of decreasing severity of erythema, scaling and pruritus, to the standard treatments: topical corticosteroids and antimycotics. However, future studies with more standardized measures of treatment outcome are recommended. More studies may also be conducted to further evaluate pimecrolimus 1% cream as a long-term maintenance therapy for seborrheic dermatitis. PMID:22142161

    2014-10-01

    Colloidal oatmeal suspensions are currently available in bath soaps, shampoos, shaving gels, and moisturizing creams, and several studies have been conducted that demonstrate the efficacy and safety of colloidal oatmeal for the treatment of inflammatory skin conditions. The diverse chemical polymorphism of oats translates into numerous clinical utilities for atopic dermatitis (AD) and eczema. Avenanthramides are the principle polyphenolic antioxidants in oats, and they have been shown to assuage inflammation in murine models of contact hypersensitivity and neurogenic inflammation and also reduce pruritogen-induced scratching in a murine itch model. Moreover, avenanthramides are a potent antioxidant. This paper will discuss various studies that have found colloidal oatmeal compounds to be beneficial in the treatment of AD and also as adjunctive treatments for AD. PMID:25607551

    Recent insights into the relevance of the epidermal barrier function and its interaction with components of the innate and adaptive immune responses in patients with atopic dermatitis (AD) give rise to a number of novel potential treatment options. In particular, the identification of loss-of-function mutations in the barrier protein filaggrin and of a diminished expression of certain antimicrobial peptides in AD skin stimulates new concepts to think beyond the T(H)1/T(H)2 paradigm. This review will focus on these most recent discoveries and will discuss new and corresponding proof-of-concept trials in patients with AD. It will further speculate on novel ways to restore the homeostasis among the 3 major components in AD skin suspected to be clinically relevant. PMID:18992925

    Sokolova, Anna; Smith, Saxon D

    2015-11-01

    Atopic dermatitis (AD) is a chronic relapsing inflammatory disease of the skin and is the most common paediatric dermatological condition. While no cure is available, it can be treated effectively if adherence to a therapeutic plan is maintained. Poor adherence to treatment is common in AD and can lead to treatment failure, which has significant impacts on the patient, family and society. A comprehensive literature search was conducted to identify factors that contribute to poor treatment adherence in childhood AD and to identify possible strategies to remedy these. Identified factors leading to poor treatment adherence include: complexity of treatment regimen, lack of knowledge, impaired quality of life, dissatisfaction with treatment strategies, infrequent follow up, corticosteroid phobia and the use of complementary and alternative medicine. Effective strategies to increase treatment adherence include: caregiver education and utilisation of education adjuncts, optimisation of the patient/caregiver-clinician relationship, early and frequent follow up and improvement of patient and caregiver quality of life.

    2015-07-01

    Coxsackievirus A6 (CV-A6) is an emerging pathogen that has in recent years been associated with atypical hand, foot and mouth disease. This manifests as a generalized papular or vesicular eruption, which may be associated with fever and systemic disturbance. We report a series of six children presenting to a single centre in the UK with disseminated CV-A6 infection on a background of atopic dermatitis (AD). Our patients exhibited a widespread papular or vesicular eruption in association with exacerbation of AD. Several of our cases mimicked eczema herpeticum, but the extent was more generalized, and individual lesions were discrete rather than clustered and were less circumscribed in character. This series highlights that CV-A6 infection may be encountered in the UK, and should be considered in the differential diagnosis of an acute exacerbation of AD, particularly in children.

    Williams, Michael R; Gallo, Richard L

    2015-11-01

    Atopic dermatitis (AD) is a common skin disease that affects a large proportion of the population worldwide. The incidence of AD has increased over the last several decades along with AD's burden on the physical and psychological health of the patient and family. However, current advances in understanding the mechanisms behind the pathophysiology of AD are leading to a hopeful outlook for the future. Staphylococcus aureus (S. aureus) colonization on AD skin has been directly correlated to disease severity but the functions of other members of the skin bacterial community may be equally important. Applying knowledge gained from understanding the role of the skin microbiome in maintaining normal skin immune function, and addressing the detrimental consequences of microbial dysbiosis in driving inflammation, is a promising direction for development of new treatments. This review discusses current preclinical and clinical research focused on determining how the skin microbiome may influence the development of AD. PMID:26404536

    BACKGROUND: There is evidence that antenatal factors play a role in the development of atopic dermatitis (AD). However, little is known about the effects of maternal lifestyle factors during pregnancy on the risk of AD in the offspring. OBJECTIVE: To investigate the effect of alcohol consumption......, time of onset, and doctor's diagnosis of AD in the offspring was obtained by interview at 18 months of age. The effect of alcohol consumption during pregnancy on the incidence of AD was analysed by Cox regression allowing for different effects of alcohol before (early infancy) and after 2 months (60...... days) of age. RESULTS: Alcohol during pregnancy was associated with a significant and dose-dependent increased risk of AD in early infancy. This effect was mainly seen in high-risk infants (two parents with allergic disease). Thus, the highest risk of AD in early infancy was seen in high-risk infants...

    Allergic contact dermatitis is a significant clinical problem in children and one that the use of essential oils and natural remedies probably exacerbates. We report a case of chronic plaque psoriasis replaced by allergic contact dermatitis in a 12-year-old boy. We suspect that the immunologic response to a hapten in lavender oil disrupted the pathogenesis of psoriasis, causing the psoriasis to temporarily "disappear." PMID:26646574
