Foot-pad dermatitis in broilers and turkeys

Foot-pad dermatitis is a condition characterised by lesions on the ventral foot-pads of poultry. It is a type of contact dermatitis, which in an early stage results in hyperkeratosis, erosions and discoloration of the skin. The erosions can develop into ulcers. In severe cases, the foot-pad lesions may cause pain which together with a deteriorated state of health constitutes a welfare issue. It has also been indicated that broilers with severe foot-pad dermatitis show slower weight gain. The aim of the present work was to improve the knowledge concerning the epidemiology of foot-pad dermatitis in meat-type poultry in Sweden. The studies were focused on surveying the occurrence of foot-pad dermatitis on Swedish commercial broiler and turkey farms, identifying endogenous and exogenous risk factors for foot-pad dermatitis in meat-type poultry and to evaluate the function of foot health as an indicator of management, hygiene and housing standards. The prevalence of foot-pad dermatitis in Swedish broilers at time of slaughter was estimated at 5-10 % for severe lesions and 10-35 % for mild lesions. The corresponding prevalence of foot-pad dermatitis in turkeys was estimated at approximately 20 % for severe lesions and 78 % for mild lesions. A significantly higher prevalence of foot-pad dermatitis was found in flocks reared on wet litter than on dry litter. In broilers, a significantly higher prevalence of lesions was found in flocks reared on thick layers of litter material than on thinner layers. There was an association between litter material and turkey foot-pad dermatitis. Type of drinker system, which is related to both water spillage and water consumption, was significantly associated with the prevalence of foot-pad dermatitis in both broilers and turkeys. There was a significant seasonal effect on the prevalence of broiler foot-pad dermatitis, with the highest prevalence found during October to January. The prevalence and severity of foot-pad dermatitis in broilers decreased over time when a surveillance programme was initiated and executed. In summary, foot-pad dermatitis in both broilers and turkeys was shown to be linked to a number of management, hygiene and housing factors, and can thus be used as an indicator of the standard of these factors. Surveillance and advisory programmes can be used successfully to decrease the incidence of foot-pad lesions in broiler and turkey populations and thus improve the health and welfare of the birds

Treatment of estrogen-induced dermatitis with omalizumab

In 1945, Drs Bernhard Zondek and Yehuda Bromberg demonstrated intradermal treatment with estrone and estradiol benzoate induced urticarial lesions in some patients.1 Fifty years later, Shelley et al,2 who introduced the concept of progesterone dermatitis several decades prior, defined estrogen dermatitis based on studies of 7 women with premenstrual flares of skin eruptions including papulovesicular, urticarial, or eczematous lesions or generalized pruritus. Previously described therapies for estrogen dermatitis include estrogen desensitization, tamoxifen, leuprolide, and oophorectomy.3 Here we report a case of estrogen-induced dermatitis successfully treated with omalizumab

Halting Progression of Stasis Dermatitis: Community Perspectives and Strategies for Prevention

Complications of stasis dermatitis including venous ulcers, osteomyelitis, and cellulitis all significantly increase morbidity and mortality of disease. Progression beyond stasis dermatitis and avoidance of the aforementioned complications are preventable with patient education and adherence to basic therapies including compression stockings and lifestyle modification. Therefore the goals of this project were to: assess the community’s understanding of stasis dermatitis and their awareness of its complications; use this information to help healthcare providers tailor their preventative health counseling accordingly; and provide education for patients on stasis dermatitis, its complications, and therapies/behavioral changes to prevent disease progression.https://scholarworks.uvm.edu/fmclerk/1377/thumbnail.jp

Role of genetic aspect in pathogenesis of atopic dermatitis

The pathogenesis of atopic dermatitis (AD) is a very complicated process that involves an intricate array of molecules. Nowadays it is generally accepted that cytokines play an important role in the progression of the clinical presentation of atopic dermatitis. However, emerging data point to the possible involvement of cornified envelope proteins in the development of skin barrier dysfunction and illness. Unfortunately, our knowledge on relation of particular genotype to progression of AD is very limited. Therefore, intensive studies are needed to increase our understanding of genetic background of atopic dermatitis. Hopefully the future research will identify new factors that help us to determine the additional risk for certain patients with atopic dermatitis

Emollient enhancement of the skin barrier from birth offers effective atopic dermatitis prevention

BackgroundAtopic dermatitis (atopic eczema) is a chronic inflammatory skin disease that has reached epidemic proportions in children worldwide and is increasing in prevalence. Because of the significant socioeconomic effect of atopic dermatitis and its effect on the quality of life of children and families, there have been decades of research focused on disease prevention, with limited success. Recent advances in cutaneous biology suggest skin barrier defects might be key initiators of atopic dermatitis and possibly allergic sensitization.ObjectiveOur objective was to test whether skin barrier enhancement from birth represents a feasible strategy for reducing the incidence of atopic dermatitis in high-risk neonates.MethodsWe performed a randomized controlled trial in the United States and United Kingdom of 124 neonates at high risk for atopic dermatitis. Parents in the intervention arm were instructed to apply full-body emollient therapy at least once per day starting within 3 weeks of birth. Parents in the control arm were asked to use no emollients. The primary feasibility outcome was the percentage of families willing to be randomized. The primary clinical outcome was the cumulative incidence of atopic dermatitis at 6 months, as assessed by a trained investigator.ResultsForty-two percent of eligible families agreed to be randomized into the trial. All participating families in the intervention arm found the intervention acceptable. A statistically significant protective effect was found with the use of daily emollient on the cumulative incidence of atopic dermatitis with a relative risk reduction of 50% (relative risk, 0.50; 95% CI, 0.28-0.9; P = .017). There were no emollient-related adverse events and no differences in adverse events between groups.ConclusionThe results of this trial demonstrate that emollient therapy from birth represents a feasible, safe, and effective approach for atopic dermatitis prevention. If confirmed in larger trials, emollient therapy from birth would be a simple and low-cost intervention that could reduce the global burden of allergic diseases

Unbearable wearables

As wearable devices play an increasing role in the management of health and disease, adverse skin reactions to wearables have become more common. However, the management of allergic contact dermatitis is challenging and new treatment options more compatible with wearable devices are needed. In a 40-year-old woman with contact dermatitis to a continuous glucose monitoring device, topical clobetasol propionate 0.05% spray proved to be an effective treatment that was compatible with the application of adhesive wearables. This case demonstrates that spray formulations of topical steroids are a good option for the treatment of dermatitis under wearable devices such as continuous glucose monitors or ostomy appliance

Proderm technology: a water- based lipid delivery system for dermatitis that penetrates viable epidermis and has antibacterial effects.

BackgroundA defective skin barrier and bacterial colonization are two important factors in maintenance and progression of atopic dermatitis and chronic allergic/irritant hand dermatitis. A water-based lipid delivery system containing physiologic lipids was previously shown to be a useful adjunct in the treatment of hand dermatitis. We tested the ability of this formulation to penetrate into the viable epidermis and in addition assessed its antibacterial properties.MethodsEpidermal penetration of the product was assessed by fluorescence microscopy. Recovery of Escherichia coli and Staphylococcus aureus MRSA from skin treated with Neosalus® foam was quantified.ResultsComponents of Neosalus® penetrated the stratum corneum and were distributed throughout the viable epidermis. Neosalus® significantly decreased recovery of both Staphylococcus aureus and Escherichia coli from the skin surface.ConclusionsThe ability of components of Neosalus® to be taken up into the viable epidermis and potentially made available for incorporation into the barrier lipids, combined with antibacterial properties, indicate that this formulation may be valuable not only in chronic hand dermatitis, but also in various other forms of dermatitis.Trial registrationCurrent Controlled Trials ISRCTN18191379 , 28/12/2018, retrospectively registered

Phenotypical Characteristics of the Biological Properties of Staphylococci Withdrawn From Patients with Allergic Dermatitis

Atopic dermatitis, eczema, allergic dermatitis occupy the main place among dermatoses, where the allergic component is leading in the onset and development of the disease. The most common complication of allergic dermatitis is the attachment of a secondary pyococcus infection, which is associated with a decrease in the antimicrobial resistance of the skin surface. Therapy of infectious lesions is complicated by the increasing resistance of the main pathogens of pyoderma - Staphylococcus aureus and Staphylococcus epidermidis - to widely used antibiotics.The aim of the research: to determine the phenotypic features of staphylococci extracted from patients with allergic dermatitis to assess their pathogenic potential.Materials and methods. The object of the study was 369 staphylococcus isolates removed from affected and intact skin sections of patients with allergic dermatitis, as well as from representative skin sections of healthy individuals undergoing inpatient treatment at the Department of Dermatology of “Institute of Dermatology and Venereology of NAMS of Ukraine”. Biochemical identification and biological properties of staphylococci were determined using methods of classical bacteriology.Results. As a result of the conducted researches, it is established that the complex of phenotypic traits of the removed staphylococcus cultures indicates the presence in the pathogen of factors related to the resistance of the host protection mechanisms and determines the intensity of the alterative action of the infectant in relation to the host organism, the phenotypic manifestation of the studied factors was higher in the staphylococcus isolates removed from the affected skin areas of patients with allergic dermatitis. Conclusions. The level and frequency of phenotypic expression of pathogenicity factors are more pronounced in microorganisms obtained from patients from affected and intact areas compared to controls, which confirms their pathogenetic role in the burden of the disease, which in turn can be used as an auxiliary differential diagnosis criterion

Aquarium dermatitis: Cercarial dermatitis in an aquarist

A 33-year-old man presented with very itchy red papules on the back of his hands and forearms. These papules appeared about 90 min after he had cleaned his aquarium in which he kept native fish and watersnails. He had obtained the watersnails some weeks before from a nearby pond. Examination of water from the aquarium revealed cercariae. The clinical diagnosis of cercarial dermatitis was corroborated. Cercarial dermatitis has repeatedly been seen in swimmers but not in aquarists keeping fish in a home aquarium
