    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.

    Background Bovine papillomatous digital dermatitis (DD) is the leading cause of lameness in dairy cattle and represents a serious welfare and economic burden. Found primarily in high production dairy cattle worldwide, DD is characterized by the development of an often painful red, raw ulcerative or papillomatous lesion frequently located near the interdigital cleft and above the bulbs of the heel. While the exact etiology is unknown, several spirochete species have been isolated from lesion m...

    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.

    The bacterial spirochetes, Treponema spp., are thought to be a major contributor to the etiology of bovine digital dermatitis (DD), a skin disease with worldwide economic impact. Hoofbath strategies are commonly used in an attempt to control and prevent the development of DD and continuing research has been done to develop an optimal hoofbath strategy for this purpose. The aim of this study was to develop a protocol that can be used as part of the screening process for candidate hoofbath disinfectants. This protocol allows an accurate determination of the in vitro minimum inhibitory concentration and minimum bactericidal concentration of a series of disinfectants for Treponema microorganisms. Assays were performed in triplicate for each of the disinfectants at 30-s and 10-min exposure times and exposed to 10 and 20% manure (vol/vol). The results of this study can be used to categorize disinfectants based on the effect of exposure and manure concentration regarding their ability to inhibit Treponema growth. This information can then aid in optimizing strategies for hoofbath-based control of DD development and spread.

    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.

  15. Short communication: Efficacy of copper sulfate hoof baths against digital dermatitis--Where is the evidence?

    2015-04-01

    Digital dermatitis is a major problem in modern dairy production because of decreased animal welfare and financial losses. Individual cow treatments are often seen as too time consuming by farmers, and walk-through hoof baths have therefore been used extensively to control digital dermatitis. For decades, copper sulfate hoof baths have been used to treat and prevent digital dermatitis. Copper sulfate has been referred to as the industry gold standard when it comes to hoof-bath chemicals. In several scientific studies testing the efficacy of other hoof-care products, copper sulfate has been used as a positive control, thereby indicating that copper sulfate has a known positive effect. However, this may not be the case. A dilemma may exist between (1) copper sulfate generally being perceived as being effective against digital dermatitis and (2) a possible lack of well-documented scientific evidence of this effect. The objective of this study was to evaluate the existing scientific literature to determine whether the efficacy of copper sulfate used in hoof baths against digital dermatitis has in fact been demonstrated scientifically. A systematic literature search identified 7 peer-reviewed journal articles describing the efficacy of copper sulfate in hoof baths as treatment or prevention of bovine digital dermatitis. Only 2 of the 7 studies compared copper sulfate to a negative control; most studies were relatively small, and often no clear positive effect of copper sulfate was demonstrated. In conclusion, the frequent claim that copper sulfate is widely reported to be effective is supported by little scientific evidence. Well-designed clinical trials evaluating the effect of copper sulfate against digital dermatitis compared with a negative control are needed. Until such studies have been made, the efficacy of copper sulfate in hoof baths against digital dermatitis remains largely unproven.

    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.

    Full Text Available Abstract The digital cushion is characterized as a modified subcutaneous tissue that absorbs the shock during gait, assists venous return of the hoof and supports a considerable part of body weight. Digital cushions have particular importance in the pathogenesis of the hoof, since they need to properly work in order to prevent compression and traumas in soft tissues. This study aimed to measure and determine how is the arrangement of these structures, and for this it was established the proportions of connective, adipose, vascular tissues and collagen fibers and collagen types found in palmar and plantar digital cushion of bovine using fore and hindlimbs of twelve adult zebu cattle of both sexes, 11 male and one female, with 269kg average carcass weight and without limb disorders. Fragments of cushions were subjected to conventional histology, cut to a thickness of 4µm and stained with Red Picrosirius. With digital optical microscope, the quantification of the connective tissue and differentiation of types of collagen used the Image Pro Plus® software, and of adipose and vascular tissue, the test point system. The mean and standard error were estimated with the GraphPad Prism 5.0 software, and then data were subjected to Kolmogorov-Smirnov normality test and Student's t-test with significance level set at 5% for determining the amount of different tissues between fore and hindlimbs of studied animals. In forelimbs the mean and standard error of the connective tissue proportion was 50.10%+1.54, of the adipose tissue was 21.34%+1.44, and of vascular tissue was 3.43%+0.28. Hindlimbs presented a proportion of connective tissue of 61.61%+1.47, 20.66%+1.53 of adipose tissue, and 3.06%+0.20 of vascular tissue. A significant difference (p<0.001 was detected in the connective tissue proportion between fore and hindlimbs.

    Digital dermatitis is a serious problem in dairy production in many countries. In many settings, it is important to evaluate the digital dermatitis status of individual cows or an entire dairy herd. Such an evaluation has traditionally been done in a hoof trimming chute. An evaluation in the milking parlor can take place without disturbing the cows to a large extent, it can be done using less labor compared with an evaluation in a hoof trimming chute, and is cheaper than using a chute. The objective was to evaluate the sensitivity and specificity of a rapid screening method for digital dermatitis in the milking parlor, without using any specialized tools and taking approximately 15 s/cow. All lactating cows in 3 commercial Danish dairy herds were included. Cows were first scored for the presence of digital dermatitis during milking and the next day all cows were scored during hoof trimming. A 6-point nominal scoring system based on a visual inspection of the digital dermatitis lesions was used. For the analysis, the scores were dichotomized (digital dermatitis positive or digital dermatitis negative). Additionally, lesions were classified as small (diameter 2 cm). Sensitivity and specificity were calculated using observations from the hoof trimming chute as the "gold standard" and observations during milking as the diagnostic test. Relatively large variation was found between herds with an overall sensitivity of 0.65 (95% confidence interval: 0.59 to 0.72) and a specificity of 0.84 (0.81 to 0.87). The sensitivity increased to 0.69 (0.62 to 0.76), when only large lesions were assessed. The method has several advantages compared with evaluation in a chute and may be a useful tool in the daily hoof health management in dairy herds.

    2000-05-01

    Papillomatous digital dermatitis is a common disease in cattle. The pastern dermatitis observed in a horse shared many of the gross characteristics of papillomatous digital dermatitis in cattle. Lesions included a mixture of proliferative and erosive changes, with a verrucose appearance in some areas. Microscopic similarities included pseudoepitheliomatous and papillomatous epidermal hyperplasia with hyperkeratosis, spongiosis of the epidermis, and intraepidermal spirochetes. The horse was also concurrently infected with Pelodera strongyloides. Papillomatous digital dermatitis in cattle is associated with poor husbandry practices. The environment of the affected horse was heavily contaminated with urine, manure, and other organic debris. Verrucous pododermatitis of horses may be the same as or similar to bovine papillomatous digital dermatitis, and these conditions have similar etiologies.

    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.

Ulcerative lesions are typically located on the plantar skin between the heel bulbs and adjacent to the coronet. Spirochetes of the genus Treponema are found in high numbers in the lesions and are likely to be involved in the pathogenesis. The aim of this study was to obtain pure cultures of spirochetes from cattle with digital dermatitis and to describe them further. Methods Tissue samples and swabs from active digital dermatitis lesions were used for culturing. Pure isolates were subjected to, molecular typing through 16S rRNA gene sequencing, pulsed-field gel electrophoresis (PFGE, random amplified polymorphic DNA (RAPD and an intergenic spacer PCR developed for Treponema spp. as well as API-ZYM and antimicrobial susceptibility tests. The antimicrobial agents used were tiamulin, valnemulin, tylosin, aivlosin, lincomycin and doxycycline. Results Seven spirochete isolates from five herds were obtained. Both 16S rRNA gene sequences, which were identical except for three polymorphic nucleotide positions, and the intergenic spacer PCR indicated that all isolates were of one yet unnamed species, most closely related to Treponema phagedenis. The enzymatic profile and antimicrobial susceptibility pattern were also similar for all isolates. However it was possible to separate the isolates through their PFGE and RAPD banding pattern. Conclusion This is the first report on isolation of a Treponema sp. from cattle with digital dermatitis in Scandinavia. The phylotype isolated has previously been cultured from samples from cattle in the USA and the UK and is closely related to T. phagedenis. While very similar, the isolates in this study were possible to differentiate through PFGE and RAPD indicating that these methods are suitable for subtyping of this phylotype. No antimicrobial resistance could be detected among the tested isolates.

    The objectives of this study were to develop and test a system for automatic washing of the hooves of dairy cows and to evaluate the effect of frequent automatic washing on the prevalence of digital dermatitis (DD). An automatic hoof washer was developed in an experimental dairy herd and tested in 6 commercial dairy herds in 2 experiments (1 and 2). In the experimental herd, automatic hoof washing resulted in cleaner hooves. In experiments 1 and 2, cows were washed after each milking on the left side only, leaving the right side unwashed as a within-cow control. In experiment 1, hooves were washed with a water and 0.4% soap solution. In experiment 2, hooves were washed with water only. In each experiment, DD was scored in a hoof-trimming chute approximately 60 d after the start of hoof washing. Data were analyzed using a generalized linear mixed model. The outcome was the DD status of each leg (DD positive or DD negative). Herd and cow within herd were included as random effects, and treatment (washing or control) was included as a fixed effect. The statistical analyses showed that the odds ratio of having DD was 1.48 in the control leg compared with the washed leg in experiment 1. In experiment 2, the odds ratio of having DD was 1.27 in the control leg compared with the washed leg. We concluded that automatic washing of hooves with water and soap can help decrease the prevalence of DD in commercial dairy herds.

    Digital dermatitis (DD) is one of the most important causes of lameness in dairy cattle worldwide. The objective of this study was to evaluate the efficacy of salicylic acid in the treatment of the disease. A total of 201 DD lesions from 173 cows from four commercial dairy herds were evaluated at day 0 during routine hoof trimming and were allocated into two groups, namely, a control group given chlortetracycline spray, and a treatment group given 10 g of salicylic acid powder applied topically within a bandage. Pain, lesion size and clinical appearance (scored M0 to M4) were evaluated on days 3, 14 and 34 post-treatment. A change to M0 was defined as healing, while changes of M2 or M4 to M1 or M3 were classified as clinical improvements. Healing rates did not differ significantly between treatment groups at days 3 and 14. By day 34 the healing rate was fivefold better (P=0.01) for the treatment vs. the control group, with healing rates of 13.6% and 3.1%, respectively. By day 3, the rate of improvement was 2.5-fold better (P=0.02) for the controls. By day 34 the overall positive effect (i.e. healing and improvement) was 1.75-fold better (P=0.05) for the treatment group. Lesions from the control group were 2.2 times more likely (P=0.09) to have a pain score equal to 2 by day 14. The proportion of lesions getting smaller by days 14 and 34 was 2.5 times higher (Psalicylic acid should be considered as an alternative to chlortetracycline for the treatment of DD as it appears more efficacious and would assist in reducing antibiotic use.

    The long-term effects of prepartum digital dermatitis (DD) on first-lactation performance were evaluated in a cohort of 719 pregnant heifers. All heifers were followed for a period of 6 mo until calving and classified on the basis of the number of DD events diagnosed during this period as type I, type II, or type III (no DD, one DD event, and multiple DD events, respectively). Health during the initial 60d in milk (DIM), reproductive and hoof health outcomes, and milk production were compared between the 3 heifer type groups. All logistic and linear models were adjusted for age, height, and girth circumference at enrollment, and the type of trace mineral supplementation during the prepartum period. Overall, cows experiencing DD during the rearing period showed worse production and health outcomes compared with healthy heifers during the first lactation. The percentages of assisted calvings, stillbirths, culled before 60 DIM, and diseased cows during the fresh period were numerically higher in type III cows compared with type I cows. However, none of these differences were statistically significant at the 95% confidence level. Significantly lower conception at first service [odds ratio (OR)=0.55, 95% confidence interval (95% CI): 0.33, 0.89] and increased number of days open (mean=24d, 95% CI: 5.2, 43) were observed in type III cows compared with type I cows. In relation to hoof health, a significantly increased risk of DD during the first lactation was found in type II and III cows (OR=5.16, 95% CI: 3.23, 8.29; and OR=12.5, 95% CI: 7.52, 21.1, respectively), as well as earlier occurrence of DD following calving (OR=59d, 95% CI=20, 96, and OR=74d, 95% CI: 37, 109). Compared with type I cows, statistically significant milk production losses during the initial 305 DIM of 199 and 335kg were estimated in type II and III cows, respectively. This difference was due to a greater rate of production decline (less persistence) after peak yield. No differences in monthly fat

    Digital dermatitis (DD) is the most important infectious claw disease in the cattle industry causing outbreaks of lameness. The clinical course of disease can be classified using 5 clinical stages. M-stages represent not only different disease severities but also unique clinical characteristics and outcomes. Monitoring the proportions of cows per M-stage is needed to better understand and address DD and factors influencing risks of DD in a herd. Changes in the proportion of cows per M-stage over time or between groups may be attributed to differences in management, environment, or treatment and can have impact on the future claw health of the herd. Yet trends in claw health regarding DD are not intuitively noticed without statistical analysis of detailed records. Our specific aim was to develop a mobile application (app) for persons with less statistical training, experience or supporting programs that would standardize M-stage records, automate data analysis including trends of M-stages over time, the calculation of predictions and assignments of Cow Types (i.e., Cow Types I-III are assigned to cows without active lesions, single and repeated cases of active DD lesions, respectively). The predictions were the stationary distributions of transitions between DD states (i.e., M-stages or signs of chronicity) in a class-structured multi-state Markov chain population model commonly used to model endemic diseases. We hypothesized that the app can be used at different levels of record detail to discover significant trends in the prevalence of M-stages that help to make informed decisions to prevent and control DD on-farm. Four data sets were used to test the flexibility and value of the DD Check App. The app allows easy recording of M-stages in different environments and is flexible in terms of the users' goals and the level of detail used. Results show that this tool discovers trends in M-stage proportions, predicts potential outbreaks of DD, and makes comparisons among

    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

    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

    Full Text Available From November of 2000 until October 2003 some epidemiologic aspects related to digital dermatitis were evaluated in 7,752 cattle, from two farms in the cities of Jataí and Orizona, Goiás state, in both the wet and dry seasons of the year. Management, age, sex and reproductive status were considered as intrinsic variables of the farm. On the other hand, the introduction of animals without podal examination, cattle transiting on foot or in trucks, access of strangers to the farm, the presence of digital dermatitis bearers in the surrounding properties, and daily visiting of milk transport trucks were considered extrinsic factors to the property. The chi-square test (?2, at 5% of significance, was used to compare the frequency of the condition between age ranges. The comparison between wet and dry seasons of the year associated to intensive and extensive managements was done by diagnosing the condition in the periods and considering the management, and then calculating the association coefficient (j to quantify the intensity of the variables considered. The odds ratio (OR was calculated for the two variables: season of the year and management system. The Spearman coefficient was used to correlate the many associated factors for the disease. Digital dermatitis was diagnosed on 161 (3.85% animals from farm A (Jataí, and in 95 (2.66% animals from farm B (Orizona. There was a difference (p<0.01 on the occurring of the condition among the ages considered, with lower association in farm A (p<0.001 (j=0.13 and moderate association (j=0.41 in farm B. No matter the age ranges, the greater occurrence was diagnosed in the dry season, when the animals were confined. This points to a relative influence from the season in the development of the condition, mainly in farm B, where there was an association (j=0.07. Rainfall and the introduction of new animals in the farm did not correlate positively with the disease. Intensive management presented a greater

    2015-07-01

    Full Text Available Digital dermatitis (DD is a bacterial disease that primarily affects the skin on the heels of cattle. It is a major cause of lameness in dairy cows and a significant problem for the dairy industry in many countries, causing reduced animal welfare and economic loss. A wide range of infection levels has been found on infected farms, prompting investigations into both farm level and animal level risk factors for DD occurrence. There also appears to be individual variation between animals in susceptibility to the disease. The identification of factors affecting individual variation in susceptibility to DD might allow changes in breeding policies or herd management which could be used to reduce DD prevalence. Factors mentioned in the literature as possibly influencing individual variation in susceptibility to DD include physical factors such as hoof conformation and properties of the skin, physiological factors such as the efficacy of the immune response, and behavioural factors such as standing half in cubicles. Further work is required to determine the influence of these factors, identify the genetic basis of variation, clarify the level of heritability of DD susceptibility and to determine how this is correlated with production and health traits currently used in breeding programmes.

    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

    The effectiveness of salicylic acid paste (PASTE) was tested for topical treatment of 25 acute and 25 chronic digital dermatitis (DD) lesions. Control groups with the same number of acute and chronic DD lesions were treated with topical oxytetracycline spray (SPRAY) and by washing only with water (HYDRO) respectively. The therapeutic effects were evaluated using a pain score, the healing rate, the lesion size and other parameters. Pre-treatment and control examinations were carried out on day 0, 4, 14 and 21. In the PASTE group, 76.0% of acute DD lesions were pain free and 64.0% of acute DD lesions were healed on day 21 showing a normal skin surface (MO). Only 28.0% of acute DD lesions treated with SPRAY and 16.0% treated with HYDRO had healed on day 21. A significantly higher healing rate was revealed in acute lesions for the PASTE compared to the HYDRO group (p salicylic acid paste and a wrap showed significantly higher healing rates within the study period, odds ratios for healing of acute lesions with PASTE were 4.5 to 6.7 times higher than with SPRAY, and 9.3 to 36.4 higher compared with HYDRO.

    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.

    2005-10-01

    Full Text Available Abstract Background The incidence of needlestick injuries in farmers and veterinary surgeons is significant and the consequences of such an injection can be serious. Case presentation We report accidental injection of bovine vaccine into the base of the little finger. This resulted in increased pressure in the flexor sheath causing signs and symptoms of ischemia. Amputation of the digit was required despite repeated surgical debridement and decompression. Conclusion There have been previous reports of injection of oil-based vaccines into the human hand resulting in granulomatous inflammation or sterile abscess and causing morbidity and tissue loss. Self-injection with veterinary vaccines is an occupational hazard for farmers and veterinary surgeons. Injection of vaccine into a closed compartment such as the human finger can have serious sequelae including loss of the injected digit. These injuries are not to be underestimated. Early debridement and irrigation of the injected area with decompression is likely to give the best outcome. Frequent review is necessary after the first procedure because repeat operations may be required.

    Advances in knowledge of neurocellulars relations have provided new directions in the understanding and treatment of numerous conditions, including atopic dermatitis. It is known that emotional, physical, chemical or biological stimuli can generate more accentuated responses in atopic patients than in non-atopic individuals; however, the complex network of control covered by these influences, especially by neuropeptides and neurotrophins, and their genetic relations, still keep secrets to be revealed. Itching and airway hyperresponsiveness, the main aspects of atopy, are associated with disruption of the neurosensory network activity. Increased epidermal innervation and production of neurotrophins, neuropeptides, cytokines and proteases, in addition to their relations with the sensory receptors in an epidermis with poor lipid mantle, are the aspects currently covered for understanding atopic dermatitis.

    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

    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.

    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

    A balanced, parallel-group, single-blinded randomized efficacy study divided into 2 periods was conducted to evaluate the effect of a premix containing higher than typically recommended levels of organic trace minerals and iodine (HOTMI) in reducing the incidence of active digital dermatitis (DD) lesions acquired naturally and induced by an experimental infection challenge model. For the natural exposure phase of the study, 120 healthy Holstein steers 5 to 7 mo of age without signs of hoof disease were randomized into 2 groups of 60 animals. The control group was fed a standard trace mineral supplement and the treatment group was fed the HOTMI premix, both for a period of 60 d. On d 60, 15 steers free of macroscopic DD lesions were randomly selected from each group for the challenge phase and transported to an experimental facility, where they were acclimated and then challenged within a DD infection model. The same diet group allocation was maintained during the 60 d of the challenge phase. The primary outcome measured was the development of an active DD lesion greater than 20mm in diameter across its largest dimension. No lesions were identified during the natural exposure phase. During the challenge phase, 55% (11/20) and 30% (6/20) of feet were diagnosed with an active DD lesion in the control and treatment groups, respectively. Diagnosis of DD was confirmed by histopathologic demonstration of invasive Treponema spp. within eroded and hyperplastic epidermis and ulcerated papillary dermis. All DD confirmed lesions had dark-field microscopic features compatible with DD and were positive for Treponema spp. by PCR. As a secondary outcome, the average DD lesion size observed in all feet was also evaluated. Overall mean (standard deviation) lesion size was 17.1 (2.36) mm and 11.1 (3.33) mm for the control and treatment groups, respectively, with this difference being driven by acute DD lesions >20mm. A trend existed for the HOTMI premix to reduce the total DD

    Because of the widespread repartition of allergens, allergic contact dermatitis is the most common inflammatory skin disease. It's the best model of dilated hypersensibility mediated by T lymphocytes cells. Atopic dermatitis and irritative dermatitis are to be distinguished to contact dermatitis. The aetiological diagnosis is the most important step of management of patients with that disease because it's the best way to avoid recurrences. The identification of cause is based on aetiological interrogatory and epicutaneous tests with 23 allergens completed with personnel products and specialised tests. Contact dermatitis can be classified according to results of aetiological management. In occupational contact dermatitis, contact dermatitis due to drugs, to metals, cosmetics, clothes and accessory and proteins. Management of patients with contact dermatitis is based on individual eviction, protection, cosmetovigilance, declaration of occupational dermatosis and allergovigilance. PMID:19102084

    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.

    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

    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.

    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

    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

Injudicious use of topical medicaments including herbal medicines and haphazard treatment were found to be the precipitating factors in 34% cases of pre-existing dermatoses. Laboratory investigations contributed little towards diagnosis except in lymphoma group; but were helpful in knowing systemic implications of the disease. Skin biopsy was found to be helpful in diagnosing underlying skin disorders in 18 cases (40.91%. Two cases (43.5% had malignancy as the cause of exfoliative dermatitis.

  2. Cobalt sensitization and dermatitis

    Thyssen, Jacob P

    2012-01-01

    : This clinical review article presents clinical and scientific data on cobalt sensitization and dermatitis. It is concluded that cobalt despite being a strong sensitizer and a prevalent contact allergen to come up on patch testing should be regarded as a very complex metal to test with. Exposure...... data together with clinical data from metal workers heavily exposed to cobalt suggest that patch-test reactions are sometimes false positive and that patch testers should carefully evaluate their clinical relevance....

    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

    Full Text Available Allergic contact dermatitis (ACD in children, until recently, was considered rare. ACD was considered as a disorder of the adult population and children were thought to be spared due to a lack of exposure to potential allergens and an immature immune system. Prevalence of ACD to even the most common allergens in children, like poison ivy and parthenium, is relatively rare as compared to adults. However, there is now growing evidence of contact sensitization of the pediatric population, and it begins right from early childhood, including 1-week-old neonates. Vaccinations, piercing, topical medicaments and cosmetics in younger patients are potential exposures for sensitization. Nickel is the most common sensitizer in almost all studies pertaining to pediatric contact dermatitis. Other common allergens reported are cobalt, fragrance mix, rubber, lanolin, thiomersol, neomycin, gold, mercapto mix, balsum of Peru and colophony. Different factors like age, sex, atopy, social and cultural practices, habit of parents and caregivers and geographic changes affect the patterns of ACD and their variable clinical presentation. Patch testing should be considered not only in children with lesions of a morphology suggestive of ACD, but in any child with dermatitis that is difficult to control.

    Full Text Available Background: The aim of these guidelines is to review the available published literature regarding the effectiveness of phototherapy and photochemotherapy in atopic dermatitis and put forward recommendations regarding their use in atopic dermatitis. Materials and Methods: A literature search was performed to collect data from PubMed, EMBASE, and the Cochrane Library published till March 2014. Keywords used were "phototherapy", "photochemotherapy", "NB-UVB", "BBUVB", "PUVA", "UVA1", "atopic dermatitis", and "atopic eczema". Systematic reviews, meta-analysis, national guidelines, randomized controlled trials, prospective open label studies, and retrospective case series in English literature mentioning use of above-mentioned keywords were reviewed. Results: Six hundred and eighty eight studies were evaluated, 38 of which fulfilled the criteria for inclusion in the guidelines. Conclusions and Recommendations: Both UV1 and narrow-band UVB are effective in significantly decreasing the eczema severity although UV1 may be preferred in acute flares and narrow-band UVB in chronic eczema, especially in adults (Level of evidence 1+, Grade of recommendation A. Among various doses of UVA1, medium dose UVA1 may be preferred over others as its efficacy is similar to high dose and better than low dose UVA1 phototherapy. Narrow-band UVB is preferred to broad-band UVB (Level of evidence 1+, Grade of recommendation A. Medium-dose UVA1 is similar in efficacy to narrow-band UVB (Level of evidence 1+, Grade of recommendation A. In children, despite its efficacy, narrow-band UVB phototherapy should be used only as a second line therapy due to its potential for long-term adverse effects (Level of evidence 2+, Grade of recommendation B.

    Full Text Available A dermatite seborreica é uma doença eritêmato-escamativa de caráter crônico-recidivante que acomete entre 1 e 3% da população geral dos Estados Unidos. Possui dois picos de incidência - o primeiro, durante os três primeiros meses de vida, e o segundo, a partir da puberdade, atingindo seu ápice entre os 40 e 60 anos de idade. Os indivíduos HIV positivos têm maior prevalência da doença, que apresenta maior intensidade e tendência à refratariedade ao tratamento. Doenças neurológicas e outras doenças crônicas também estão associadas ao desenvolvimento da dermatite seborreica. Como mecanismo fisiopatogênico, reconhece-se que o fungo Malassezia sp., presente na pele de indivíduos suscetíveis, leve a uma irritação não-imunogênica a partir da produção de metabólitos à base de ácidos graxos insaturados deixados na superfície cutânea. Este artigo faz uma revisão da literatura sobre dermatite seborreica, com ênfase nos aspectos imunogenéticos, formas clínicas e tratamento.Seborrheic dermatitis is a chronic relapsing erythematous scaly skin disease, the prevalence of which is around 1 to 3% of the general population in the United States. It has two incidence peaks, the first in the first three months of life and the second beginning at puberty and reaching its apex at 40 to 60 years of age. The prevalence of seborrheic dermatitis is higher in HIV-positive individuals and the condition tends to be more intense and refractory to treatment in these patients. Neurological disorders and other chronic diseases are also associated with the onset of seborrheic dermatitis. The currently accepted theory on the pathogenesis of this disease advocates that yeast of Malassezia spp., present on the skin surface of susceptible individuals, leads to a non-immunogenic irritation due to the production of unsaturated fatty acids deposited on the skin surface.

    Full Text Available Dermatitis herpetiformis is an autoimmune bullous disease that is associated with gluten sensitivity which typically presents as celiac disease. As both conditions are multifactorial disorders, it is not clear how specific pathogenetic mechanisms may lead to the dysregulation of immune responses in the skin and small bowel, respectively. Recent studies have demonstrated that IgA and antibodies against epidermal transglutaminase 3 play an important role in the pathogenesis of dermatitis herpetiformis. Here, we review recent immunopathological progress in understanding the pathogenesis of dermatitis herpetiformis.

    Phototherapy is a second-line treatment for moderate to severe atopic dermatitis (AD) that effectively decreases cutaneous inflammation with minimal or no systemic side effects. Children in grade school, adolescents, and adults may benefit from phototherapy, when they have chronic AD refractory to first-line topical treatments. This review focuses on six approaches for phototherapy in AD: (1) broadband ultraviolet B (UVB), (2) Goeckerman regimen (coal tar + broadband UVB), (3) narrowband UVB, (4) excimer lasers for targeted areas, (5) combination UVA/UVB, and (6) UVA-1. Phototherapy can be very effective in some individuals, but it is limited by inconvenience and adverse effects, including limited access to in-office treatment, difficulty adhering to thrice-weekly schedule, flaring from excessive heat, and increased risk of skin cancer. Dosing regimen and treatment concerns are reviewed. PMID:27638440

    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

    Full Text Available 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.

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.

    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. PMID:26943310

    Full Text Available The nervous system, the immune system, and the cutaneous system are not independent systems, but are closely associated and use the same language of cytokines and neurotransmitters. Atopic dermatitis (AD is exacerbated by several factors, such as emotional stress, scratching and sweating. This review presents the role of neuropeptides (NP in AD. In AD, abnormalities occur in distribution of some types of neural filaments and in the associated active NP. Nerve fibre increases. Nerve fibres for substance-P (SP and calcitonin gene-related peptide (CGRP are positive, The cutaneous concentration of SP decreases while vasoactive-intestinal polypeptide (VIP increases. Immunohistochemical examination has revealed neuropeptide-Y (NPY-positive dendritic epidermal cells in AD lesions but no somatostatin (SOM fibres. Neuromediators modulate functions of all cutaneous cellular types, which are all part of the neuroimmunocutaneous system (NCIS: endothelial cells, glandular cells, fibroblasts, epidermal cells and immune cells. Conclusion: during the course of AD, the NICS is destabilized. Evidence show that NP can also be responsible for the induction and maintenance of the cutaneous inflammation process and confirm an involvement in the pathogenesis of AD. Release of the NP by cutaneous nerve potentially explains the role of emotional stress, scratching and sweating in exacerbation of AD.

    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.

    Preservatives are biocidal chemicals added to food, cosmetics, and industrial products to prevent the growth of microorganisms. They are usually nontoxic and inexpensive and have a long shelf life. Unfortunately, they commonly cause contact dermatitis. This article reviews the most important classes of preservatives physicians are most likely to encounter in their daily practice, specifically isothiazolinones, formaldehyde and formaldehyde-releasers, iodopropynyl butylcarbamate, methyldibromoglutaronitrile, and parabens. For each preservative mentioned, the prevalence of sensitization, clinical presentation of contact dermatitis, patch testing concentrations, cross reactions, and related legislation will be discussed. Mandatory labeling of preservatives is required in some countries, but not required in others. Until policies are made, physicians and patients must be proactive in identifying potential sensitizers and removing their use. We hope that this article will serve as a guide for policy makers in creating legislation and future regulations on the use and concentration of certain preservatives in cosmetics and industrial products.

    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

    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.

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.

    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.

    Atopic dermatitis is a chronic inflammatory skin condition including severe pruritus, xerosis, visible eczematous skin lesions that mainly begin early in life. Atopic dermatitis exerts a profound impact on the quality of life of patients and their families. The estimated lifetime prevalence of atopic dermatitis has increased 2~3 fold during over the past 30 years, especially in urban areas in industrialized countries, emphasizing the importance of life-style and environment in the pathogenesis of atopic diseases. While the interplay of individual genetic predisposition and environmental factors contribute to the development of atopic dermatitis, the recent increase in the prevalence of atopic dermatitis might be attributed to increased exposure to various environmental factors rather than alterations in human genome. In recent decades, there has been an increasing exposure to chemicals from a variety of sources. In this study, the effects of various environmental chemicals we face in everyday life - air pollutants, contact allergens and skin irritants, ingredients in cosmetics and personal care products, and food additives - on the prevalence and severity of atopic dermatitis are reviewed.

    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.

  4. Comparison of Droplet Digital PCR and qPCR for the Quantification of Shiga Toxin-Producing Escherichia coli in Bovine Feces.

    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.

    Seborrheic dermatitis is a common skin condition in infants, adolescents, and adults. The characteristic symptoms-scaling, erythema, and itching-occur most often on the scalp, face, chest, back, axilla, and groin. Seborrheic dermatitis is a clinical diagnosis based on the location and appearance of the lesions. The skin changes are thought to result from an inflammatory response to a common skin organism, Malassezia yeast. Treatment with antifungal agents such as topical ketoconazole is the mainstay of therapy for seborrheic dermatitis of the face and body. Because of possible adverse effects, anti-inflammatory agents such as topical corticosteroids and calcineurin inhibitors should be used only for short durations. Several over-the-counter shampoos are available for treatment of seborrheic dermatitis of the scalp, and patients should be directed to initiate therapy with one of these agents. Antifungal shampoos (long-term) and topical corticosteroids (short-term) can be used as second-line agents for treatment of scalp seborrheic dermatitis. PMID:25822272

    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.

    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

    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.

    A healthy 58-year-old woman developed an asymptomatic papular eruption of the neck, cheek, abdomen, arms, and flexures. There was an 8-year history of the lesions, which had erupted when the patient started a strict vegetarian diet. Lesions lasted 3 to 5 days, cleared without scarring, and were associated with burning and increased tearing of the eyes. The biopsy specimen showed an interstitial granulomatous dermatitis without vascular injury, collagen alteration, or mononuclear atypia. The eruption cleared when the patient omitted soy products from her diet. It subsequently recurred with intake of even minimal amounts of soy. Interstitial granulomatous dermatitis is a histologic pattern of inflammation that generates a broad differential diagnosis. No previous reports of interstitial granulomatous dermatitis related to soy products are available in the literature.

  16. Modern Aspects of Phototherapy for Atopic Dermatitis

    2012-01-01

    Full Text Available Phototherapy has still great importance in the treatment of atopic dermatitis, though costs, compliance, and long-term risks narrow its relevance. In spite of its long history, up to now, the therapeutic regimes are mostly empirical. Narrowband UVB und UVA1 are the most frequently applied regimens in atopic dermatitis with proven efficacy. However, even for these modalities randomized prospective and controlled studies are still pending. Advances in photoimmunology and molecular biology had demonstrated that phototherapy targets inflammatory cells, alters cytokine production, and has a significant antimicrobial effect within atopic skin. This paper summarizes the current literature on the different regimes of phototherapy and also discusses therapeutic modalities like photochemotherapy and extracorporeal photopheresis. These more complex regimes should be restricted to severe cases of atopic dermatitis, which are refractory to topical treatment.

    We report a case of radiation recall dermatitis caused by trastuzumab. A 55-year-old woman with metastatic breast cancer received palliative first-line trastuzumab/paclitaxel and a salvage partial mastectomy with lymph node dissection was subsequently performed. In spite of the palliative setting, the pathology report indicated that no residual carcinoma was present, and then she underwent locoregional radiotherapy to ensure a definitive response. After radiotherapy, she has maintained trastuzumab monotherapy. Nine days after the fifth cycle of trastuzumab monotherapy, dermatitis in previously irradiated skin developed, with fever. Radiation recall dermatitis triggered by trastuzumab is extremely rare. A high fever developed abruptly with a skin rash. This may be the first case of this sort to be reported.

    From a clinical point of view, the prevalence of allergic contact dermatitis (ACD) among children and adolescents seems to be low. However, many children have dermatitis, most often atopic dermatitis. In selected cases, ACD is suspected, and the child is tested. The question remains, whether...... the prevalence of ACD in children really is low or whether the possibility of ACD is not sufficiently considered. During the last decade, reports have appeared on series of children and adolescents with contact allergy and ACD. Few cases have been reported in infants, but the development of contact allergy...... and ACD increases with age. Most studies include selected groups of children and adolescents with suspected ACD.

    Full Text Available Atopic dermatitis is a common disease which varies widely in clinical presentation at different ages and places. Although authors working in western countries on white races have suggested many criteria, there is no uniform set which can be used in large population studies in this part of the world. Hence keeping in mind differences in environment and ethnicity of population, the present study was carried out. Seventy- three patients of atopic dermatitis and 71 age matched controls were studied. All the subjects were examined using a set of 34 potentially useful clinical features selected from different studies, including features for evaluation of photosensitivity. Multiple regression technique was used for analysing the data. It was found that 6 clinical features were diagnostic, 1. presence of itch, 2. history of flexural involvement, 3. history of dry skin, 4. family history of atopy, 5. personal history of diagnosed asthma and 6, visible flexural dermatitis. Photosensitivity was not a significant feature.

  1. Atopic dermatitis and the nervous system.

    Science.gov (United States)

    Misery, Laurent

    2011-12-01

    Due to the narrow associations between the skin, immune system, and nervous system, nerve endings are very important in the pathophysiology of inflammatory dermatoses and especially in atopic dermatitis. Many neurotransmitters and nerve growth factors that are released in blood or skin are involved in neurogenic inflammation, which dramatically enhance the inflammation induced by immune cells. During times of stress, their release is highly enhanced. In atopic dermatitis lesions, there are many specific changes in skin neurobiology and neurophysiology. These interesting data suggest that novel therapeutic possibilities can be imagined.

  2. Evaluation and management of acute radiation dermatitis

    International Nuclear Information System (INIS)

    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)

  10. Management of seborrheic dermatitis and pityriasis versicolor.

    Science.gov (United States)

    Faergemann, J

    2000-01-01

    Pityriasis (tinea) versicolor and seborrheic dermatitis are two very common skin diseases. Pityriasis versicolor is a chronic superficial fungal disease usually located on the upper trunk, neck, or upper arms. In pityriasis versicolor, the lipophilic yeast Malassezia (also know as Pityrosporum ovale or P. orbiculare) changes from the blastospore form to the mycelial form under the influence of predisposing factors. The most important exogenous factors are high temperatures and a high relative humidity which probably explain why pityriasis versicolor is more common in the tropics. The most important endogenous factors are greasy skin, hyperhidrosis, hereditary factors, corticosteroid treatment and immunodeficiency. There are many ways of treating pityriasis versicolor topically. Options include propylene glycol, ketoconazole shampoo, zinc pyrithione shampoo, ciclopiroxamine, selenium sulfide, and topical antifungals. In difficult cases, short term treatment with fluconazole or itraconazole is effective and well tolerated. To avoid recurrence a prophylactic treatment regimen is mandatory. Seborrheic dermatitis is characterized by red scaly lesions predominantly located on the scalp, face and upper trunk. There are now many studies indicating that Malassezia plays an important role in this condition. Even a normal number of Malassezia will start an inflammatory reaction. Mild corticosteroids are effective in the treatment of seborrheic dermatitis. However, the disease recurs quickly, often within just a few days. Antifungal therapy is effective in the treatment of seborrheic dermatitis and, because it reduces the number of Malassezia, the time to recurrence is increased compared with treatment with corticosteroids. Antifungal therapy should be the primary treatment of this disease.

  16. Comparative analysis of human and bovine teeth: radiographic density

    Directory of Open Access Journals (Sweden)

    Jefferson Luis Oshiro Tanaka

    2008-12-01

    Full Text Available Since bovine teeth have been used as substitutes for human teeth in in vitro dental studies, the aim of this study was to compare the radiographic density of bovine teeth with that of human teeth to evaluate their usability for radiographic studies. Thirty bovine and twenty human teeth were cut transversally in 1 millimeter-thick slices. The slices were X-rayed using a digital radiographic system and an intraoral X-ray machine at 65 kVp and 7 mA. The exposure time (0.08 s and the target-sensor distance (40 cm were standardized for all the radiographs. The radiographic densities of the enamel, coronal dentin and radicular dentin of each slice were obtained separately using the "histogram" tool of Adobe Photoshop 7.0 software. The mean radiographic densities of the enamel, coronal dentin and radicular dentin were calculated by the arithmetic mean of the slices of each tooth. One-way ANOVA demonstrated statistically significant differences for the densities of bovine and human enamel (p 0.05. Based on the results, the authors concluded that: a the radiographic density of bovine enamel is significantly higher than that of human enamel; b the radiodensity of bovine coronal dentin is statistically lower than the radiodensity of human coronal dentin; bovine radicular dentin is also less radiodense than human radicular dentin, although this difference was not statistically significant; c bovine teeth should be used with care in radiographic in vitro studies.

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

    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.

    2008-01-01

    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. PMID:19920986

    Allergies are often suspected in cats and they are mainly hypersensitivity reactions against insect bites, food- or environmental allergens. Cats, with non flea induced atopic dermatitis, normally present with one oft he following reaction patterns: miliary dermatitis, eosinophilic dermatitis, selfinduced alopecia or head and neck excoriations. None of these reaction patterns is nevertheless pathognomonic for allergic dermatitis, therefore the diagnosis is based on the one hand on the exclusion of similar diseases on the other hand on the successful response on a certain therapy. Recently a study on the clinical presentation of cats with non flea induced atopic dermatitis was published. In this study certain criteria for diagnosing atopy in cats were proposed. For therapy of allergic cats cyclosporin, glucocorticoids, antihistamines, hypoallergenic diets and allergen specific immunotherapy are used. This article should provide a recent overview on the clinical symptoms, diagnosis and therapy of feline allergic dermatitis.

    Seborrheic dermatitis is a chronic superficial fungal infection of the skin, particularly affecting sites rich in sebaceous glands. Although the precise etiology of seborrheic dermatitis is uncertain, yeasts of the genus Malassezia are known to play a causative role. Ciclopirox is a broad-spectrum, hydroxypyridone-derived, synthetic antifungal agent, which also has anti-inflammatory properties. Ciclopirox is effective both in vitro and in vivo against Malassezia yeasts, making it a valuable option for the treatment of seborrheic dermatitis. Varying frequencies and concentrations of ciclopirox shampoo have been shown to be effective and safe in the treatment of seborrheic dermatitis of the scalp.

    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.

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.

    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

    Atopic dermatitis is a chronic inflammatory skin disease with a complex pathogenesis, where changes in skin barrier and imbalance of the immune system are relevant factors. The skin forms a mechanic and immune barrier, regulating water loss from the internal to the external environment, and protecting the individual from external aggressions, such as microorganisms, ultraviolet radiation and physical trauma. Main components of the skin barrier are located in the outer layers of the epidermis (such as filaggrin), the proteins that form the tight junction (TJ) and components of the innate immune system. Recent data involving skin barrier reveal new information regarding its structure and its role in the mechanic-immunological defense; atopic dermatitis (AD) is an example of a disease related to dysfunctions associated with this complex.

    Full Text Available A 50-year-old mining engineer at Dhanbad was having air bome contact Dermatitis suspected to be caused by Xanthium strumarium. Patch tests with a 15% aqueous extract of air dried leaves showed a severe positive reaction, but the patient also had positive patch tests with Parthenium hysterphorus and a few other weeds and trees known to cause air-borne contact dermatitis. The titre of contact hypersensitivity with the extract of Xanthium struma′rium was more than 1:100,000 and for Parthenium hysterophrous it was 1:10 indicating a high degree of hypersensitivity to Xanthium strumarium. Further tests in 14 other patients revealed a high prevalence of cross sensitivity between these two plants both of which belong to the compositae family.

    2015-05-01

    Full Text Available Malassezia spp. is a genus of lipophilic yeasts and comprises the most common fungi on healthy human skin. Despite its role as a commensal on healthy human skin, Malassezia spp. is attributed a pathogenic role in atopic dermatitis. The mechanisms by which Malassezia spp. may contribute to the pathogenesis of atopic dermatitis are not fully understood. Here, we review the latest findings on the pathogenetic role of Malassezia spp. in atopic dermatitis (AD. For example, Malassezia spp. produces a variety of immunogenic proteins that elicit the production of specific IgE antibodies and may induce the release of pro-inflammatory cytokines. In addition, Malassezia spp. induces auto-reactive T cells that cross-react between fungal proteins and their human counterparts. These mechanisms contribute to skin inflammation in atopic dermatitis and therefore influence the course of this disorder. Finally, we discuss the possible benefit of an anti-Malassezia spp. treatment in patients with atopic dermatitis.

    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.

    During the last years of his life, Oscar Wilde (1856-1900) suffered from a suppurating otitis media as well as from an unidentified skin disease. The eruption was localized to his face, arms, chest and back and itched severely. A new theory is suggested, based on the fact that Wilde almost certainly used a dye to conceal his rapidly graying hair. He sensitized himself to p-phenylenediamine and developed a stubborn allergic contact dermatitis. Patch testing, the only proof of such a diagnosis, had not yet been devised.

    Vicks VapoRub (VVR) is a commonly used inhalant ointment that helps relieve symptoms of upper respiratory tract infections. It contains several plant substances, including turpentine oil, eucalyptus oil, and cedar leaf oil, which can potentially irritate or sensitize the skin, as well as camphor, menthol, nutmeg oil, and thymol. Although many reports describe allergic contact dermatitis (ACD) to the various constituents in VVR ointment, there are no cases of VVR directly causing ACD. We present a case of a patient who developed an ACD secondary to application of her VVR. PMID:20487662

    2016-01-01

    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.

    2001-12-01

    Significant numbers of humans with atopic dermatitis develop Malassezia-specific IgE. Immediate skin-test reactivity to Malassezia has been demonstrated in atopic dogs. The aim of this study was to compare the serum IgG and IgE response to Malassezia in atopic dogs with and without clinical evidence of Malassezia dermatitis and/or otitis, nonatopic dogs with clinical evidence of Malassezia dermatitis and/or otitis and healthy dogs. Cytology was used to diagnose clinically significant Malassezia dermatitis and otitis. Contact plate cultures confirmed the validity of this technique. Reproducible enzyme-linked immunosorbent assays for Malassezia-specific IgG and IgE in canine serum were established. Atopic dogs had significantly higher serum IgG and IgE levels than either healthy dogs or nonatopic dogs with clinical evidence of Malassezia dermatitis and/or otitis. There was no significant difference in IgG and IgE levels between atopic dogs with and without clinical evidence of Malassezia dermatitis and/or otitis. The implications of these findings in the pathogenesis and management of canine atopic dermatitis are discussed. PMID:11844222

    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.

  3. Probiotics and Atopic Dermatitis in Children

    Directory of Open Access Journals (Sweden)

    Gian Vincenzo Zuccotti

    2012-07-01

    Full Text Available There is increasing interest in the potential beneficial role of probiotic supplementation in the prevention and treatment of atopic diseases in children. Probiotics are defined as ingested live microorganisms that, when administered in an adequate amount, confer a health benefit to the host. They are mainly represented by Lactobacilli and Bifidobacteria. Several epidemiological data demonstrate that intestinal microflora of atopic children is different from the one of healthy children. Many literature data show that probiotics may modulate the intestinal microflora composition and may have immunomodulatory effect. Based on this hypothesis, probiotics are supposed to confer benefits to allergic diseases. Administration of probiotics when a natural population of indigenous intestinal bacteria is still developing could theoretically influence immune development by favoring the balance between Th1 and Th2 inflammatory responses. For this reason, some studies have evaluated the potential impact of probiotics supplementation in the prevention of atopic dermatitis, with contrasting results. Clinical improvement in immunoglobulin (IgE-sensitized (atopic eczema following probiotic supplementation has been reported in some published studies and the therapeutic effects of probiotics on atopic dermatitis seemed to be encouraging. However, as far as the usefulness of probiotics as a prevention strategy is concerned, results are still inconclusive. In fact, the clinical benefits of probiotic therapy depend upon numerous factors, such as the type of bacteria, dosing regimen, delivery method and other underlying host factors, such as age and diet. More studies are still needed to definitively prove the role of probiotics in the treatment of allergic eczema.

    Diapers create particular conditions of moisture and friction, and with urine and feces come increased pH and irritating enzymes (lipases and proteases). Fungi can take advantage of all these factors. Candida yeasts, especially C. albicans, are responsible for the most frequent secondary infections and are isolated in more than 80 % of cases. Correct diagnosis is important for ensuring the correct prescription of topical antimycotics. Nystatin, imidazoles and ciclopirox are effective. It is important to realize there are resistant strains. Dermatophytes can infect the diaper area, with the most common agent being Epidermophyton floccosum. The clinical characteristics of dermatophytosis are different from those of candidiasis, and it can be diagnosed and treated simply. Malassezia yeasts can aggravate conditions affecting the diaper area, such as seborrheic dermatitis, atopic dermatitis, and inverse psoriasis. Additional treatment is recommended in this case, because they usually involve complement activation and increased specific IgE levels. Erythrasma is a pseudomycosis that is indistinguishable from candidiasis and may also occur in large skin folds. It is treated with topical antibacterial products and some antimycotics.

    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.

    2016-01-01

    Dermatitis artefacta, a self-inflicted intentional dermatosis is a very rare diagnosis in childhood. In a large proportion, the underlying psychiatric disorders go unidentified due to lack of collaboration between dermatologist and psychiatrist. The underlying psychological reasons for childhood dermatitis artefacta include emotional distress and interpersonal conflicts. A multitude of psychosocial factors interact to precipitate this disorder. Here, we report a child with dermatitis artefacta who was diagnosed with attention deficit hyperactivity disorder during psychiatric evaluation. Parental expectations and sibling rivalry were further increasing the stress of the index child. Appropriate diagnosis and management lead to treatment compliance and functional improvement in the child. PMID:27195043

    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.

    Full Text Available Occupational dermatitis is one of the most common occupational diseases in clinical practice. Prevalence varies according to the job activities and types of exposure, with figures of up to 37% reported in the literature. Its origin may be irritant or allergic. Atopy and frequent hand washing or exposure to wetness or humidity is described has been described as risk factors, while evidence for gender and tobacco consumption, among others, is controversial. Diagnosis is based on physical examination, etiological patch testing and certification of occupational origin using standardized criteria. The condition has been associated with reduced productivity, absenteeism and occupational changes, as well as significant decreases in the quality of life of patients. Prevention is based primarily on education and restriction of exposure. These strategies are coupled with the treatment, which include the use of drugs such as topical steroids and calcineurin inhibitors.(X Close Abstract

Occupational factors were seen to have some influence in relation to the causative agents as indicated by higher positivity of vegetables in housewives; detergents, metals, rubber, leather, plastics in businessmen, teachers, clerks and students; fertilizers or animal foods in farmers; drugs in doctors and nurses and chromium and cobalt in massons.

  1. Coin exposure may cause allergic nickel dermatitis

    DEFF Research Database (Denmark)

    Thyssen, Jacob P; Gawkrodger, David J; White, Ian R;

    2012-01-01

    Nickel is used in coins because the metal has beneficial properties, including price, colour, weight, and corrosion resistance, and also because it is easy to stamp. It has often been claimed that the duration of skin contact with coins is too short to cause nickel release and dermatitis. However......, it is well known by dermatologists specialized in occupational skin diseases, and by their nickel-allergic patients, that hand eczema in cashiers and other professionals who handle coins may be caused or aggravated by nickel release from coins. In this review, we present evidence from past studies showing...... that nickel-containing coins can indeed pose a risk for those who handle them. For protection of the health of consumers, cashiers, and other workers who handle coins, it is suggested that coins without nickel release should be used as a substitute for the high nickel-releasing coins currently in widespread...

    2014-01-01

    Background Vulvar eczematous dermatitis predisposes patients to superimposed infections, which may result in late diagnosis and architectural destruction. Methicillin resistant staphylococcus aureus (MRSA) infection is on the rise in genitalia and lower extremities. Case 44 year-old female presented with recurrent vulvar lesions and pain. A diagnosis of methicillin resistant staphylococcus aureus in the setting of eczema was achieved with concomitant use of photography and dermatopathologic review. Antibiotics were tailored to the resistant infection and preventative moisturization therapy was utilized. Conclusion Awareness of dermatologic conditions affecting the vulva is principal in routine gynecologic care. Barrier protection of eczematous vulvar skin may prevent superficial infections. The regular use of photographic documentation and dermatopathology may decrease time to diagnosis with infrequent conditions. PMID:23763013

    2016-04-01

    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.

    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.

    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.

    We have previously shown that both atopic and normal dogs generate an IgG response to antigens of Malassezia pachydermatis. The aim of this study was to compare IgE responses to separated proteins of M. pachydermatis in 28 atopic dogs with Malassezia dermatitis and 22 clinically normal dogs using Western immunoblotting. Six different detection systems were evaluated in order to assess sensitivity and eliminate nonspecific binding and cross-reactivity. The protocol yielding the best results utilized a monoclonal mouse antidog IgE, an alkaline phosphatase conjugated goat antimouse IgG which had been passed through a canine IgG column 3 times, a chemiluminescent substrate and a digital imaging system. Proteins of 45, 52, 56 and 63 kDa were recognized by more than 50% of the atopic dog sera and thus represented major allergens. Only a minority of normal dogs showed faint IgE binding to these proteins. The results indicate that the majority of atopic dogs with Malassezia dermatitis have a greater IgE response than normal dogs, suggesting an IgE-mediated immune response may be clinically important in the pathogenesis of the disease.

    2000-10-01

    We identified Malassezia species isolated from 42 patients with seborrhoeic dermatitis, 17 patients with atopic dermatitis, 22 patients with pityriasis versicolor, 35 normal subjects and 73 healthy medical students. Regarding the prevalence of Malassezia species in the 35 normal subjects, the frequency of isolation of Malassezia globosa was 22%, M. sympodialis 10% and M. furfur 3%. M. slooffiae, M. pachydermatis, M. restricta and M. obtusa were infrequently isolated from normal skin. Two different species were isolated coincidentally from seven samples. In the patients with atopic dermatitis, M. furfur was isolated more frequently from lesional skin (21%) than non-lesional skin (11%). However, there was no statistical significance. Therefore, this result, by itself, is insufficient to prove that M. furfur should be considered to be an exacerbating factor of atopic dermatitis. In seborrhoeic dermatitis, M. furfur (35%) and M. globosa (22%) were isolated from lesional skin on the face at significantly high rates in comparison with the normal subjects. Therefore, M. furfur and/or M. globosa may be pathogens of seborrhoeic dermatitis. M. globosa was isolated at a frequency of 55% from lesional skin of pityriasis versicolor, while all other species were below 10%. These data suggest that the pathogenic species of pityriasis versicolor is M. globosa.

    2012-01-01

    Full Text Available Contact dermatitis is produced by external skin exposure to an allergen, but sometimes a systemically administered allergen may reach the skin and remain concentrated there with the aid of the circulatory system, leading to the production of systemic contact dermatitis (SCD. Metals such as nickel, cobalt, chromium, and zinc are ubiquitous in our environment. Metal allergy may result in allergic contact dermatitis and also SCD. Systemic reactions, such as hand dermatitis or generalized eczematous reactions, can occur due to dietary nickel or cobalt ingestion. Zinc-containing dental fillings can induce oral lichen planus, palmoplantar pustulosis, and maculopapular rash. A diagnosis of sensitivity to metal is established by epicutaneous patch testing and oral metal challenge with metals such as nickel, cobalt, chromium, and zinc. In vitro tests, such as the lymphocyte stimulating test (LST, have some advantages over patch testing to diagnose allergic contact dermatitis. Additionally, the determination of the production of several cytokines by primary peripheral blood mononuclear cell cultures is a potentially promising in vitro method for the discrimination of metal allergies, including SCD, as compared with the LST.

    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.

    Onset of atopic dermatitis and occurrence of related skin lesions are influenced by various environmental factors in humans, and companion animals. Several studies have demonstrated an association between passive smoking and the development of atopic dermatitis in children. This association has never been investigated in the dog to our knowledge. We enrolled 161 dogs seen at dermatology and vaccination consultations over a six-month period for this study. Dog owners were asked to complete a questionnaire, to evaluate the exposure of the dog to tobacco smoke. The atopic or non-atopic status of the dog was assessed on the basis of Favrot's criteria (history, clinical examination and cutaneous cytology for Malassezia). Analysis of the data for the 161 dogs enrolled revealed a significant association between high levels of passive exposure to tobacco smoke (cigarette consumption divided by the area of the home) and the presence of atopic dermatitis in the dogs (OR, 4.38; 95% CI, 1.10-17.44; p=0.03; NNH (number needed to harm) 3, 95% CI 2-52). The prevalence of atopic dermatitis showed a slight, but non-significant association with breed predisposition. Dogs with high levels of exposure to tobacco smoke may have a higher risk of atopic dermatitis than non-exposed dogs. PMID:24491262

    Atopic dermatitis (AD), or eczema, can be a very challenging disease to manage. The etiology of the disease is not completely understood, and its incidence has risen in the past 10 years to more than 10% of the population. AD is characterized primarily by intense itching and the development of papules, scaly lesions, fissures, and crusting. The onset occurs primarily in childhood, and much of the disease management is conducted by the family. Patients and their families often experience multiple recurrences and exacerbations, repeated attempts at cures and treatments, lowered self-esteem of the child, impaired growth and development of the child, loss of sleep, discipline problems, and multiple clinic and emergency department visits for exacerbations. Management primarily consists of prevention (i.e., good daily skin care and management of environmental trigger factors such as infection, irritants, emotional stress, and allergens). These children and their families need education and the support of health care professionals. This article outlines specific techniques to help parents and children manage AD at home and minimize exacerbations. PMID:9579351

    Full Text Available A forty-three year old house-wife developed dermatitis over the center of forehead following application of kumkum, bindi and sticker (except one brand since six months. Patch testing with various brands of kumkum and regularly available sticker used by the patient elicited positive reaction except one brand used by the patient. Kumkum is made by mixing turmeric (Curcuma longa powder with small amount of lime (calcium hydroxide. She was patch tested with turmeric, to which she developed positive reaction. Subsequently she was patch tested with turmeric powder boiled and air-dried and also the acetone-extract and precipitate of the powder. She tested positive to all the extracts and precipitates, but the turmeric powder which was dried by boiling did not elicit positive reaction. She was advised to use boiled and dried turmeric to make kumkum for use. However, the kumkum powder prepared following boiling had lost its adhesive property and hence was unacceptable. She was offered Castellani′s paint and eosin with starch for application. Both were acceptable for 2 months, but she subsequently developed irritant reaction to the paint with starch. She continues to use the non-allergic sticker (Kanchan sticker kumkum while we are trying to find other alternatives to kumkum.

    Seborrheic dermatitis is a multifactorial skin disease characterized by a chronic course with periods of exacerbation and remission. 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. This is a review of literature evaluating the efficacy and safety profile of topical pimecrolimus 1% cream for the treatment of seborrheic dermatitis. PMID:23441238

    Full Text Available Nail art (creation and decoration of artificial nails is a growing fashion trend. Proportionally to its popularity, the number of allergic reactions to the materials used has recently increased. We report the case of a nail art operator who developed occupational allergy to acrylates, manifested with the unusual simultaneous presence of asthma and dermatitis. Cutaneous lesions only affected areas not covered by individual protection devices or clothes, even if such areas were not in direct contact with acrylates, suggesting airborne allergic contact dermatitis. While respiratory problems were solved with the correct use of a mask at the workplace, facial dermatitis proved impossible to avoid or control and, for this reason, the patient had to change her work.

    12 cases of occupational allergic contact dermatitis caused by decorative plants were diagnosed in a 14-year period. The patients were middle-aged, and their average exposure time was 13 years. The plant families and plants causing occupational contact dermatitis were Compositae (5 patients; chrysanthemum, elecampane, gerbera, feverfew), Alstroemeriaceae (5 patients, Alstroemeria), Liliaceae (4 patients; tulip, hyacinth), Amaryllidaceae (2 patients; narcissus) and Caryophyllaceae (2 patients; carnation, cauzeflower). The known chemical allergens causing dermatitis were tuliposide-A and sesquiterpene lactones, such as alantolactones and parthenolide, in the Liliaceae and Compositae families. 7 of the 12 patients were able to continue their work; 5 were not because of severe relapses of skin symptoms. The plant allergen and extract series currently available are of great help in the diagnosis. PMID:8807225

    Full Text Available In dogs, dermatitis due to mixed mite infestation is rare. During the five-year period of study, two dogs were identified suffering from dermatitis due to mixed Demodex and Sarcoptes mites. Upon clinical examination dogs had primary and secondary skin lesions on face, around the ears, chin, neck, fore limbs and lateral abdomen. Microscopic examination of skin scrapings revealed Demodex and Sarcoptes mites. Both dogs were treated with daily oral ivermectin at 100 to 400 μg/kg body weight as incremental doses, external application of amitraz and supportive treatments with topical antimicrobial shampoo. After completion of forty-two days of therapy, dogs were recovered from the dermatitis.

    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.

    Treatment of purified bovine coronavirus (Mebus strain) with pronase destroyed the integrity of virion surface glycoproteins gp140, gp120, gp100, reduced the amount of gp26 and destroyed the hemagglutinating activity of the virus. Bromelain, on the other hand, destroyed the integrity of gp120, gp100 and gp26 but failed to remove gp140 and failed to destroy viral hemagglutinating activity. These experiments suggest that gp140 is the virion hemagglutinin. Immunoblotting studies using monospecific antiserum demonstrate that gp140 is a disulfide-linked dimeric structure reducible to monomers of 65 kDa.

    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.

    Full Text Available Background : Footwear dermatitis represents a distinct and common group among all types of contact dermatitis cases seen in India. This ailment, however, often remains undiagnosed, misdiagnosed or empirically diagnosed without pinpointing the contributory allergens. Aims : This study was undertaken to detect the epidemio-allergological pattern of footwear dermatitis in India. Methods : A total number of 155 cases with footwear dermatitis were evaluated from July 2005 to June 2006, by detailed history and clinical examination. They were patch tested using Indian Standard Battery (ISB approved by the Contact and Occupational Dermatoses Forum of India (CODFI with pre- and post patch-test counseling. 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.

    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.

    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

    Atopic dermatitis (AD) is a common disease in childhood that is a serious burden on patients and their families. Most AD is mild and can be managed with the use of emollients and standard therapy consisting of topical corticosteroids or topical calcineurin inhibitors. However, in a subgroup of patients with moderate to severe AD, the disease is recalcitrant to topical therapy and systemic treatments become necessary. Short courses of systemic corticosteroids are often used in clinical practice, but their use is controversial. International guidelines suggest that in the case of acute flare-ups, patients might benefit from a short course of systemic corticosteroids, but long-term use and use in children should be avoided. Ciclosporin is an immunosuppressant agent that acts directly on cells of the immune system, with an inhibitory effect on T cells. When AD cannot be controlled by standard topical therapies, ciclosporin significantly decreases symptom scores, disease extent, pruritus and sleep deprivation, and improves quality of life. The most frequent adverse effects associated with the use of ciclosporin are hypertension and renal dysfunction, but they are usually reversible after drug discontinuation. Ciclosporin has been found to be safely used, effective and well tolerated in children with severe AD. However, studies to assess the long-term effectiveness and safety of ciclosporin in AD are lacking. In patients for whom ciclosporin is not suitable, or when there is a lack of response, alternative drugs should be considered, such as azathioprine or interferon-gamma. Intravenous immunoglobulins and the monoclonal antibody infliximab only have a place in the systemic therapy of AD when other drugs have failed. Mycophenolate mofetil has recently been introduced in the treatment of recalcitrant AD. Efalizumab and omalizumab are monoclonal antibodies with a possible future role in the treatment of AD, but further studies are needed. PMID:19275273

    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.

    Radiation recall dermatitis (RRD) is an acute skin toxicity caused by different anticancer or antibiotic drugs within a former completely healed irradiation field. Predictive factors for RRD are not known and its mechanisms are not completely understood. A case of RRD induced by docetaxel and successfully treated by an antioxidant ointment (Mapisal {sup registered}) is presented here. Such an ointment might be useful not only in RRD therapy, but also in the treatment of high-grade dermatitis induced by radiotherapy and thus may contribute to the improvement of patients' quality of life and to the scheduled completion of cancer therapies.

    Full Text Available Context: Atopic dermatitis is a chronic inflammatory skin disease resulting from interactions between environmental and genetic factors. Recent studies link atopic dermatitis with asthma and with eosinophilic esophagitis. Case Report: Based on this association, we investigated by indirect immunofluorescence the immunoreactivity patterns on monkey esophagus substrate utilizing the serum of a patient with severe atopic dermatitis. We also examined the patient′s skin biopsy by H&E histology and immunohistochemistry. We detected strong deposits of albumin, IgE, IgG, IgD, IgA, Complement/C1q and mast cell tryptase in multiples structures of the skin, as well as a broad pattern of intraepithelial staining on monkey esophagus. Strong staining positivity was also detected within the inflammatory infiltrate around the upper dermal vessels, as well as additional positive staining for the human leukocyte antigen system antigens DR DP and DQ. Conclusion: Our findings demonstrate that there could be an indication for testing patients with severe atopic dermatitis for autoreactivity to filaggrin (anti-keratin antibodies utilizing monkey esophagus. Larger studies are needed to clarify any immunologic interaction between the reactivity to albumin and food allergens that may sensitize patients via the esophageal mucosa.

    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

  7. Occupational allergic contact dermatitis caused by thiourea compounds.

    1994-10-01

    Thiourea compounds are mainly used as accelerators in the rubber industry, but also in other industries, e.g., as antioxidants in the graphics industry. Thiourea compounds may provoke allergic contact dermatitis, although the number of reported cases is relatively low. During 1985-1991, we had 5 patients with allergic patch test reactions caused by thiourea compounds. 1 of our patients had to use a knee brace after an occupational accident. He developed allergic contact dermatitis caused by the knee brace, probably because he had become sensitized to diethylthiourea. 2 patients were probably sensitized by diphenylthiourea in neoprene gloves. A florist had an allergic patch test reaction to diphenylthiourea and might have been sensitized by fungicides or pesticides, which break down into thioureas. It is often difficult, however, to detect the source of thiourea compound sensitization. If the patient has contact dermatitis and has been exposed to products that may contain thiourea compounds (or compounds that break down into thiourea compounds), such as rubber, PVC plastic or adhesive, diazo paper, paints or glue remover, anticorrosive agents, fungicides or pesticides, patch testing with a series of thiourea compounds needs to be performed. If patch testing with thiourea compounds is not performed, allergic contact dermatitis caused by thiourea compounds is not likely to be diagnosed. PMID:7842680

This metal is used in numerous industrial and consumer products, including stainless steel, magnets, metal plating, coinage, and special alloys, and is therefore almost impossible to completely avoid in daily life. Nickel contact dermatitis can represent an important morbidity, particularly in patients with chronic hand eczema, which can lead to inability to work, a decrease in quality of life and significant healthcare expenses. Therefore, its management is of great importance.

    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.

    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.

  1. The multiple factors affecting the association between atopic dermatitis and contact sensitization

    DEFF Research Database (Denmark)

    Thyssen, J P; McFadden, J P; Kimber, I

    2014-01-01

    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...

    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

    Textile dye allergy is frequently caused by azo dyes, which can cross-react with structurally similar compounds, including paraphenylenediamine. A case of allergic contact dermatitis to azo textile dyes, presenting principally as a sock dermatitis, is presented. The patient also gave a history of an episode of scalp dermatitis consistent with contact allergy to paraphenylenediamine in hair dye. It is proposed that paraphenylenediamine sensitization from a temporary skin tattoo may have been the primary sensitizing event for these reactions. PMID:15527435

    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.

    Full Text Available Contact dermatitis is an inflammatory response of the skin to an exogenous substance (irritant and/or allergen. It can be classified as follows: Irritant contact dermatitis, Allergic contact dermatitis, Photo contact, phototoxic dermatitis, Immediate contact reactions, Non-eczematous reactions Only the superficial regions of the skin are affected in contact dermatitis. Inflammation of the affected tissue is present in the epidermis and the outer dermis. 1 Unlike contact urticaria, in which a rash appears within minutes of exposure and fades away within minutes to hours, contact dermatitis takes days to appear. In our study we have shown the list of most common allergens found positive in our patients. STUDY DESIGN: It was a cross sectional study. METHOD: Study was conducted in mahatma Gandhi hospital Jaipur over a period of 4 months of duration. Patients suspected to have contact dermatitis were subjected to patch testing. Based on the history clinical signs and symptoms. Total 42 patients were short listed in 4 months of duration. RESULT: Our study showed that the most common allergen showing patch test positivity in both males and females were nickel sulphate, cophony, and cobalt sulphate. Patients showed significant improvement in their dermatitis after avoidance of the offending agent. CONCLUSION: Patch test is the method of choice and the “gold standard” in the detection of contact allergy and allergic contact dermatitis

    2004-01-01

    Nickel is the most ubiquitous contact allergen among children and adolescents. Metal blue jeans buttons and belts have been noted to cause nickel dermatitis around the umbilicus. For these children, traditional teaching is strict avoidance of all pants with metal snaps/buttons, particularly blue jeans. In this study we tested 90 pairs of blue jeans and 47 belts for nickel using the dimethylglyoxime spot test. Only 10% of blue jeans tested positive, while 53% of belts tested positive. Furthermore, 10 pairs of nickel-negative blue jeans remained negative after 10 washings. Overall we found no resistance to testing in clothing stores. From these results, we recommend that patients with allergic contact dermatitis secondary to nickel need not strictly avoid blue jeans and metal belt buckles. Rather, families should be encouraged to use the dimethylglyoxime spot test to test these items for nickel prior to purchase.

    In the past decade, the availability of powerful molecular techniques has accelerated the pace of discovery of several new primary immunodeficiencies (PID) and revealed the biologic basis of other established PID. These genetic advances, in turn, have facilitated more precise phenotyping of associated skin and systemic manifestations and provide a unique opportunity to better understand the complex human immunologic response. These continuing medical education articles will provide an update of recent advances about PID that may be encountered by dermatologists through their association with eczematous dermatitis, infectious, and non-infectious cutaneous manifestations. Part I will discuss new primary immunodeficiencies that have an eczematous dermatitis. Part II will focus on primary immunodeficiencies that greatly increase susceptibility to fungal infection and the noninfectious presentations of PID. PMID:26282794

    The demonstration of IgE receptors on the surface of epidermal dendritic cells and on other antigen presenting cells is a crucial element in the understanding of the pathophysiological role of these cells in the genesis of atopic disease, and especially the atopic dermatitis (AD). The sensibilisation phase to an aeroallergen at the level of nasal or bronchial mucosa and even at the skin may be mediated by dendritic cells expressing Fc epsilon RI. Distinct forms of AD may then represent the equivalent of the ellicitation phase of the classical allergic contact dermatitis. Fc epsilon RI would lead, via specific IgE, to an efficient antigen capture, to the activation of the dendritic cells and finally to an antigen presentation. Thus, AD may represent the paradigma of an IgE-mediated type IV reaction. PMID:8786892

    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

    Paraphenylenediamine (PPD) is a potent skin allergen found in permanent hair dye and temporary henna tattoo ink. Several cases of adverse skin reactions to PPD have been reported in the literature. Here we present a case involving a patient who acquired a temporary tattoo while vacationing in Mexico and subsequently developed contact dermatitis at the tattoo site. He provided a history of permanent hair dye use in the past with associated cutaneous reaction. Temporary tattoos have become increasingly popular with travelers and as a result so have reports of associated allergic contact dermatitis. Of concern is cross-reaction of PPD to related compounds, severe reactions in younger populations and sequelae including increased sensitization, permanent scarring, and persistent postinflammatory hyperpigmentation.

    Background Topical antimicrobial drugs are indicated for limited superficial pyodermitis treatment, although they are largely used as self-prescribed medication for a variety of inflammatory dermatoses, including atopic dermatitis. Monitoring bacterial susceptibility to these drugs is difficult, given the paucity of laboratory standardization. Objective To evaluate the prevalence of Staphylococcus aureus topical antimicrobial drug resistance in atopic dermatitis patients. Methods We conducted a cross-sectional study of children and adults diagnosed with atopic dermatitis and S. aureus colonization. We used miscellaneous literature reported breakpoints to define S. aureus resistance to mupirocin, fusidic acid, gentamicin, neomycin and bacitracin. Results A total of 91 patients were included and 100 S. aureus isolates were analyzed. All strains were methicillin-susceptible S. aureus. We found a low prevalence of mupirocin and fusidic acid resistance (1.1% and 5.9%, respectively), but high levels of neomycin and bacitracin resistance (42.6% and 100%, respectively). Fusidic acid resistance was associated with more severe atopic dermatitis, demonstrated by higher EASI scores (median 17.8 vs 5.7, p=.009). Our results also corroborate the literature on the absence of cross-resistance between the aminoglycosides neomycin and gentamicin. Conclusions Our data, in a southern Brazilian sample of AD patients, revealed a low prevalence of mupirocin and fusidic acid resistance of S. aureus atopic eczema colonizer strains. However, for neomycin and bacitracin, which are commonly used topical antimicrobial drugs in Brazil, high levels of resistance were identified. Further restrictions on the use of these antimicrobials seem necessary to keep resistance as low as possible.

    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.

    Full Text Available Introduction. Atopic dermatitis (AD is a chronic dermatological disease of multifactorial pathogenesis with persistent pruritus and extreme skin dryness including typical skin changes caused by many interactions between genetic and environmental factors. The study aims to evaluate the selected aspects of quality of life in AD. Material and methods. To what extent does the disease affect the daily practice of the patient and their family, what are their expenditures in connection with the treatment, and also how they perceive themselves and emotional, sexual, social behavior. 71 adult subjects 48(68% women and 23 (32% men were selected from the allergology clinics in the region of Silesia for this questionnaire based study. Results. Pruritus was felt by everyone, skin pain by 69%, and skin burning by 86%. The great majority of subjects had some constrains in doing housework due to skin complaints. The disease also affected professional work and school achievements. Almost everyone agreed that money spent on medication purchase and skin care agents impacted on financial resources. Atopic dermatitis affected 75% in social functioning, leisure time, sports practicing. The disease affected self-esteem level and confidence. Half of the examined subjects experienced bad feelings in contact with a partner, or felt stigmatized by negative reactions of the environment because of the skin appearance. Often atopic dermatitis caused problems with sound sleep (65% various emotional disorders and also disorders in the sexual sphere (32%. Every fourth subject felt depressed and every seventh thought of suicide. Conclusions. Atopic dermatitis is a disease which adversely influences many aspects of life and undoubtedly impairs the quality of life in a serious and distressing way. Therefore its treatment should be supported by psychotherapy.

    Full Text Available Problem statement: Atopic diseases, including asthma, eczema and allergic rhinitis, are characterized by a chronic inflammatory reaction mediated by T helper 2 cells, while type 1 diabetes mellitus is mediated by T helper 1 cells. Approach: The aim of this study was to compare the prevalence of atopic dermatitis between children with type 1 diabetes mellitus and age-matched controls. We conducted a case-control study enrolling 150 cases with type 1 diabetes mellitus between 2-20 years from pediatric endocrine out patient clinic and 450 controls randomly selected from the general population matched on sex and age. The diagnosis of atopic dermatitis was determined for patients and controls by the Hanifin and Rajka’s diagnostic criteria. Results: From 150 cases, 75 (50% were male and 75 (50% were female, with the age between 2 and 20 and among the 450 controls, 228 were male (50. 66% and 222 were female (49.33% the age was as the case. Dermatitis past or present, was identified in 1.3% of cases and 3.1% of controls, a difference which was not statistically significant (P>0.05. 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.

    Canine atopic dermatitis (CAD) is a chronic relapsing inflammatory skin disease occurring in 10% of the canine population. Although most studies have focused on the pathophysiological mechanism involved in CAD, the detrimental impact of CAD on quality of life has received only little attention. Hair cortisol analysis is becoming a valuable tool in monitoring chronic stress. To further validate this approach in CAD, we compared the hair cortisol concentration of atopic dogs with that of healthy conditioned dogs. The extent and severity of cutaneous lesions of atopic dermatitis were assessed according to modified CADESI-03 scores. In addition, skin barrier function was evaluated by measuring transepidermal water loss (TEWL) and stratum corneum conductance. The correlation between CAD severity and hair cortisol concentration was evaluated. The level of hair cortisol evaluated by ELISA assay showed that the atopic dermatitis group had significantly increased cortisol levels compared to that of the healthy control group. A significant positive correlation was identified between hair cortisol level and the CADESI score in CAD patients. The TEWL value of the cubital flexor of the forelimb in the atopic group was significantly higher compared to the healthy controls. These findings imply that the hair cortisol analysis can be an effective and objective biomarker in assessment of long-term stress of CAD patients.

    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.

    1997-02-01

    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.

    Full Text Available Introduction:The etiology of seborrheic dermatitis is not fully understood. It has been observed that a number of anascogenic yeasts of Malassezia spp. is related to the intensity of the symptoms. The aim of the study is to measure the concentration of selected inflammatory factors IL-2, IL-4, IFN-γ and TNF-α in the serum by an immunoenzymatic method, as well as to confirm the relationship between the studied factors and the clinical condition of the patients (sex, the intensity of skin lesions according to the Scaparro scale and, finally, to compare the results with the control group.Material/Methods:The total number of subjects who participated in the study was 66. The control group (C consisted of 30 volunteers (23 females and 7 males, with no clinical disorders, aged 24–65 (37.41±6.08 years. Thirty-six patients with seborrheic dermatitis (16 females and 20 males, aged 19–76 (38.61±13.77, made up the study group. The determination of IL-2, IL-4, IFN-γ and TNF-α was performed by ELISA using a Human High Sensitivity kit (Diaclone, France. Clinically, the intensity of the disease process was evaluated on the Scaparro et al. scale, as modified by Kaszuba.Results:We observed statistically significantly higher levels of IL-2 and IFN-γ in patients with seborrheic dermatitis compared to the control group.Conclusions:We conclude that seborrheic dermatitis is a dermatosis characterized by a cell type immune response with an important role of IFN-γ and IL-2.

    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.].

Materials and Methods: Complete dermatological and allergological examination was performed; these parameters were examined: food allergy (to wheat flour, cow milk, egg, peanuts and soy, the occurrence of bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. The statistical evaluation of the relations among individual parameters monitored was performed. Results: Food allergy was altogether confirmed in 65 patients (29% and these patients suffer significantly more often from bronchial asthma and allergic rhinitis. Persistent atopic dermatitis lesions and positive data in family history about atopy are recorded significantly more often in patients with confirmed food allergy to examined foods as well. On the other hand, the onset of atopic dermatitis under 5 year of age is not recorded significantly more often in patients suffering from allergy to examined foods. Conclusion: Atopic dermatitis patients suffering from food allergy suffer significantly more often from allergic rhinitis, bronchial asthma, persistent eczematous lesions and have positive data about atopy in their family history.

    2014-06-01

    The purpose of this review was to identify whether supplementation with prebiotics and/or probiotics help prevent the development or reduce the severity of atopic dermatitis in children less than three years of age. Since 1997, immunostimulatory supplements, such as prebiotics and probiotics, have been investigated. Various supplementations include probiotics (single strain or mix), probiotics with formula, probiotics mix with prebiotics, and prebiotics. In this narrative review, we examined 13 key articles on prebiotics and/or probiotics, and their effects on infant atopic dermatitis. Among the selected studies, a total of 3,023 participants received supplements or placebo. Eight out of the 13 (61.5%) studies reported a significant effect on the prevention of atopic dermatitis after supplementation with probiotics and/or prebiotics. Five out of the 13 (38.5%) studies indicated significant reduction in the severity of atopic dermatitis after supplementation. Based on the available studies, supplementation with certain probiotics (Lactobacillus rhamnosus GG) appears to be an effective approach for the prevention and reduction in severity of atopic dermatitis. A mix of specific probiotic strains prevented atopic dermatitis among infants. Based on studies with prebiotics, there was a long-term reduction in the incidence of atopic dermatitis. Supplementation with prebiotics and probiotics appears useful for the reduction in the severity of atopic dermatitis. Additional interventional studies exploring prebiotics and probiotics are imperative before recommendations can be made.

    Background The differential diagnosis of psoriasis and seborrheic dermatitis can be difficult when both conditions are localized to the scalp without the involvement of other skin sites. Objective We aimed to evaluate the histopathological differences between psoriasis and seborrheic dermatitis on the scalp and identify favorable criteria for their differential diagnosis. 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

The thymus is a key organ of the cellular immune response early in life. We hypothesized that atopic dermatitis...... is associated with an unbalanced establishment of the peripheral T-lymphocyte system. This cross-sectional study was performed to compare thymus sizes in patients with atopic dermatitis and healthy controls. Thirty-seven children with current atopic dermatitis were enrolled and compared with 29 healthy controls....... An interview and medical examination were performed by one doctor, an ultrasound scan was performed within 3 days of the examination, and the thymus index, a marker of thymus size, was measured. The thymus index was on average 32% higher (95% CI 3%-67%) in children with active atopic dermatitis compared...

  10. Allergic contact dermatitis: A comparison between atopic and non-atopic individuals

    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.

  12. Bioelectrical impedance analysis of bovine milk fat

    International Nuclear Information System (INIS)

    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.

    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: 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.

    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 and Design: Atopic dermatitis (AD is a multifactorial disease in which Malassezia species are also considered to be one of the factors that exacerbate AD. We have developed a culture-independent method for analyzing cutaneus Malassezia load in patients with atopic dermatitis.Materials and Methods: The diversity of Malassezia flora in Turkish patients with atopic dermatitis of three different clinical severities (mild, moderate, and severe were compared using quantitative real time polymerase chain reaction (qRT-PCR method. Fourthy-seven individuals with AD and seventy-five adult healthy individuals were sampled in this study. Skin samples were collected by stripping the face and neck of each subject. Fungal DNA extraction was performed and the detection of Malassezia DNA by real-time PCR was conducted. Results: Total number of patients was 122, including 47 patients and 72 healthy controls (62 female, 60 male. Quantitative analysis of Malassezia colonization in the AD group and healthy control group was not significantly different between the AD and healthy control groups. In patients with severe AD, Malassezia colonization was not different that in mild and moderate AD patients and healthy individuals, and the differences among them were not statisticaly significant (p=0.409.Conclusion: We could not find any difference in our patient group in terms of Malassezia colonization rate, although we had hypothesized. We could not show a fungal factor for the severity of the disease in AD patients. Japanese authors showed such a kind of relationship in the past. Besides, skin diseases should be evaluated carefully for the presence of microorganisms as an important factor of pathogenesis of the disease. (Turk­derm 2011; 45: 206-9

    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

    This double-blinded noninferiority clinical trial evaluated the use of oral fluconazole for the treatment of Malassezia dermatitis in dogs by comparing it with use of an accepted therapeutic agent, ketoconazole. Dogs presenting with Malassezia dermatitis were treated with either fluconazole or ketoconazole in addition to cephalexin for concurrent bacterial dermatitis. Statistically significant improvements in cytologic yeast count, clinical signs associated with Malassezia dermatitis, and pruritus were seen with both antifungal treatments. There was no statistical difference between the treatments with regard to the magnitude of reduction in these parameters. These results suggest that fluconazole is at least as effective as ketoconazole for the treatment of dogs with Malassezia dermatitis. PMID:20957617

    Full Text Available Atopic dermatitis, perhaps more than other dermatologic diseases, has garnered much attention in the realm of alternative medicine. This may be because its etiopathogenesis is incompletely understood, it is increasingly common, and it waxes and wanes often without clear precipitants, opening up many opportunities for misinterpretation. Herein we explore the evidence for a number of different alternative and complementary therapies, from textiles to vitamin supplements. By definition, none have enough data to be deemed “effective” in a conventional sense, but it is hopeful that some show promising evidence that may one day lead to mainstream acceptance with further research.

    2010-12-01

    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

    Atopic dermatitis (AD, or atopic eczema) is an inflammatory itchy skin disease. AD patients often have high serum immunoglobulin E (IgE) levels, T-cell activation and eosinophilia in peripheral blood. The dermal infiltrate of AD contains mainly T-cells, eosinophils and dendritic cells. Epicutaneous patch tests with aeroallergen application for 24-48 h can induce eczematous lesions in sensitized patients with AD. This is named the atopy patch test (APT).

    Dermatitis in the rubber industry has diminished markedly in this century, but the problem still is the second most common occupational disease. Contributing agents include natural rubber, as latex concentrate or dry crumb, as well as the various additives used for conditioning. Primary, secondary, and tertiary prevention all have roles in reduction of incidence and severity of impairment. The choice of gloves and skin care methods must be based on a consideration of the efficacy of the materials and the environment in which they will be used. Careful attention to diagnosis yields benefits in treatment course and impairment reduction. Teamwork by occupational physicians, nurses, industrial hygienists, employees, and management is required.

    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

In some cases however, other plants have also been noticed to give positive patch test reactions. 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.

    Acrylic nails, including sculptured nails and the new ultraviolet-curable gel polish lacquers, have been associated with allergic contact dermatitis (ACD). We report 2 cases of ACD to acrylic nails with severe onychodystrophy and psoriasiform changes including onycholysis and subungual hyperkeratosis. In both cases, the patients did not realize the association between the use of acrylate-based manicures and nail changes. One patient had been previously misdiagnosed and treated unsuccessfully for nail psoriasis. The informed clinician should elicit a history of acrylic manicure in patients with these nail changes, especially in cases of suspected nail psoriasis refractory to treatment. Patch testing is a useful tool in confirming diagnosis. PMID:27170940

    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.

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, ...

    The Winter 2012 (vol. 14 no. 3) issue of the Nexus Network Journal features seven original papers dedicated to the theme “Digital Fabrication”. Digital fabrication is changing architecture in fundamental ways in every phase, from concept to artifact. Projects growing out of research in digital fabrication are dependent on software that is entirely surface-oriented in its underlying mathematics. Decisions made during design, prototyping, fabrication and assembly rely on codes, scripts, parameters, operating systems and software, creating the need for teams with multidisciplinary expertise and different skills, from IT to architecture, design, material engineering, and mathematics, among others The papers grew out of a Lisbon symposium hosted by the ISCTE-Instituto Universitario de Lisboa entitled “Digital Fabrication – A State of the Art”.

    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

    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.

    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.

    1989-04-01

    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.

    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 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.

    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 Abstract: This article describes five outbreaks of swinepox in backyard pigs in Northeastern Brazil. It affected backyard pigs from herds of poor hygienic-sanitary conditions with severe fly and lice infestations. The morbidity ranged from 33.3 to 100% among affected herds, with mortality reaching up to 60%. The affected pigs developed multifocal to coalescent gray to white papules and blisters in the skin, with eventual eruptions, evolving to erosions and crusts. In addition to skin lesions, affected piglets presented apathy, anorexia and fever. The disease was auto-limiting, resolving within 15 to 25 days. Histological examination revealed proliferative and ulcerative vesiculopustular dermatitis with ballooning degeneration of epithelial cells, perivascular inflammatory infiltrates of lymphocytes, plasma cells, neutrophils, eosinophils and some macrophages in the dermis. Intracytoplasmic eosinophilic inclusions were consistently observed in keratinocytes. Total DNA extracted from fresh tissue fragments obtained from one outbreak and formalin-fixed, paraffin-embedded (FFPE tissue from the other four outbreaks was submitted to polymerase chain reaction (PCR for Swinepox virus (SWPV and Vaccinia virus (VACV. Genetic SWPV material was identified by PCR in fresh material from one outbreak. Nucleotide sequencing and phylogenetic analysis of the PCR amplicons (viral polymerase gene demonstrated 100% homology with sequences from SWPV. All tissues were PCR negative for VACV. Swine poxvirus is present in backyard pigs in Northeastern Brazil, indicating the need of including SWPV in the differential diagnosis of dermatitis in pigs.

  3. Changes of epidermal mu-opiate receptor expression and nerve endings in chronic atopic dermatitis.

    There is increasing evidence that neuropeptides such as a substance P, neurotrophins or beta-endorphin, an endogenous agonist for mu-opioid receptor, are involved in the pathogenesis of atopic dermatitis in which mental stress and scratching deteriorate the disease. mu-Opioid receptor, a G-protein-coupled receptor, can be downregulated and internalized by agonists and other factors in vitro. In this study, we investigated the regulation of mu-opioid receptor and nerve endings in atopic dermatitis patients. Skin biopsies from atopic dermatitis patients revealed a significant downregulation of mu-opiate receptor expression in epidermis of atopic dermatitis. Permeabilization of the skin showed that the receptor in keratinocytes from atopic dermatitis is internalized. The mRNA expression pattern of the mu-opiate receptor is different in epidermis taken from patients with chronic atopic dermatitis compared to normal skin. In atopic dermatitis, the mRNA is concentrated in the subcorneal layers of the epidermis and in normal skin in the suprabasal layers. Staining of the nerve endings using protein gene product 9.5 shows a different pattern of epidermal nerve endings in normal skin compared to atopic dermatitis. In normal skin, the epidermal nerve endings are rather thick. However, in atopic dermatitis, the epidermal nerve endings are thin and run straight through the epidermis. Based on these observations and combining the 'intensity' and 'pattern' hypothesis, we propose a new theory especially for histamine-unrelated, peripheral induction of chronic pruritus. We suggest that 'itch' is elicited in the epidermal unmyelinated nerve C-fibers and 'pain' in the dermal unmyelinated nerve fibers. The downregulation of the opioid receptor in the epidermis contributes to the chronic itching. We call this new hypothesis the 'layer hypothesis'.

    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

    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.

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

    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.

    This report describes the antemortem diagnosis and antemortem and postmortem findings of superficial necrolytic dermatitis with hepatopathy (i.e., hepatocutaneous syndrome) in a cat. A 5-year-old Maine coon was evaluated because of a history of pruritic alopecia and liver enzyme elevations. Abdominal ultrasonography revealed a reticular pattern to the hepatic parenchyma. Histopathological findings of the liver were nodular regeneration with bands of vacuolated hepatocytes and bile duct hyperplasia, characteristic of the hepatopathy frequently associated with superficial necrolytic dermatitis. Skin histopathology revealed multifocal parakeratosis, midepidermal spongiosis, and basal cell hyperplasia consistent with superficial necrolytic dermatitis.

    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

    There are increasing numbers of education programmes for children and young people with atopic dermatitis. These also include directions for the treatment of atopic dermatitis. However, the methods to be followed and the treatment to be applied are usually not clearly defined or explained. Presented are the key aspects of the local treatment of atopic dermatitis to be taught to children. The introduction of a basic therapeutic concept helps sort out which are the best preparations to use, some with and others without active ingredients. The interactions between basic care, active ingredients and skin conditions are explained in such a way that children can understand them.

    1999-09-01

    We report the case of a a 60 year-old worker in the pharmaceutical industry who suffered from recurring contact dermatitis. Initially the contact dermatitis was limited to the hands; later on it became generalized. The patient had been working on a drug filling line in a pharmaceutical plant for more than 20 years. Eight years after starting this job he had developed allergic hand dermatitis to 2,6-diaminopyridine (patch test positive); this healed upon cessation of exposure. Ten years later he again developed hand dermatitis which progressed to generalized dermatitis and conjunctivitis. Under systemic and local therapy with corticosteroids and cessation of work, it healed nearly completely. Four months after returning to work, the patient experienced a first episode of severe asthma and generalized dermatitis with conjunctivitis following exposure to hydroxychloroquine the day before. The asthma and dermatitis improved after systemic corticosteroid therapy and stopping work. His condition continued to fluctuate, when though the patient was transferred at work and now wore rubber gloves. Eight months later he again developed a generalized dermatitis. Patch testing revealed delayed-type sensitizations to hydroxychloroquine (tested in concentrations of 0. 1%, 0.5%, 1% and 2%). Equivalent tests in five healthy volunteers were negative. The patch test reactions were pustular, while a biopsy was interpreted as a multiform contact dermatitis reaction. Bronchial exposure with hydroxychloroquine dust produced a delayed bronchial obstruction over the next 20 hours, which progressed to fever and generalized erythema (hematogenous contact dermatitis). After removing exposure to 2,6-diaminopyridine and hydroxychloroquine, the patient went on to develop a contact dermatitis to latex (patch test positive). However, skin prick tests with latex and patch tests with rubber additiva were negative. Hydroxychloroquine is well known to cause drug reactions. To our knowledge, contact

    1998-01-01

    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....

    Photogrammetry is the use of photography for surveying primarily and is used for the production of maps from aerial photographs. Along with remote sensing, it represents the primary means of generating data for Geographic Information Systems (GIS). As technology develops, it is becoming easier to gain access to it. The cost of digital photogrammetric workstations are falling quickly and these new tools are therefore becoming accessible to more and more users. Digital Photogrammetry is particularly useful as a text for graduate students in geomantic and is also suitable for people with a good basic scientific knowledge who need to understand photogrammetry, and who wish to use the book as a reference.

    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

    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.

    The newer and emerging treatments for atopic dermatitis (AD) focus on blockade of inflammatory cytokines, especially those that derive from T helper cell type 2 (TH2) and are associated with a pathway of immunoglobulin E (IgE) sensitization. Among the proinflammatory cytokines that have been identified as promising therapeutic targets are chemoattractant receptor-homologous molecule expressed on TH2 cells (CRTH2), IgE, thymic stromal lymphopoietin (TSLP), and several monoclonal antibodies that block key cytokine pathways in the innate immune response. Two agents that have been studied in phase III clinical trials are the boronbased phosphodiesterase-4 (PDE-4) inhibitor, crisaborole, and dupilumab, an antibody that inhibits the interleukin-4/ IL-13 receptor α chain.

    1979-05-01

    A total of 79 nickel-sensitive patients (65 women, 14 men) were examined with regard to a present or past eczema corresponding to contact with metallic buttons in blue jeans; 63% of the women and 64% of the men had or had had eczema of this kind. Among 40% of the women below 30 years this was the primary site of manifestation. The seriousness of this sensitivity is illustrated by the fact that two-thirds of the nickel sensitive patients with button dermatitis had or had had eczema of the hands. The conclusion is that blue jean buttons should be made of a material which does not contain nickel, for instance zinc alloys which are presently used for some metallic buttons, or they should be designed in such a way that the button does not directly contact the skin.
