Incontinence-associated dermatitis in older adults in residential care settings: a point prevalence study.

Incontinence-associated dermatitis (IAD) is a skin inflammation caused by contact with urine or faeces or both. It has a negative effect on the patient's quality of life and is indicative of the care provided. However, globally there is a lack of empirical data on the prevalence of IAD. AIM: To identify, for the first time, the proportion of older adults in extended care settings in Ireland affected by IAD. DESIGN: Cross-sectional, multisite, point prevalence survey, across three community extended care settings for older people in Ireland. METHODS: Two clinical nurse specialists, using the Scottish Excoriation and Moisture Related Skin Damage Tool, identified the presence of IAD through clinical observation and visual skin inspection. IAD prevalence was calculated for the total population and incontinent population sets using percentages and confidence intervals (CI). RESULTS: The prevalence of incontinence was 86.4% (n=165), a significantly higher proportion were female (P=0.003). The point prevalence of IAD across the total population and incontinent population was 11.5% (22/191; 95% CI, 7.4-19.9%) and 13.3% (22/164; 95% CI, 8.5-19.5%), respectively. Being incontinent was associated with being female, more dependent (Barthel), having possible cognitive impairment, poorer mobility (Braden and Waterlow) and a high risk of pressure ulcers (Waterlow). A logistic regression analysis found no predictor variables for IAD among the variables that met the cut-off point for this analysis. CONCLUSIONS: The study provides the first point prevalence empirical data on the occurrence of IAD in Ireland. It can inform decision-making on future planning and budgeting of new quality improvement projects and act as a benchmark for ongoing auditing of IAD.

Imatinib-induced dermatomyositis sine dermatitis - a rare case report.

Idiopathic Inflammatory Myopathies are rare conditions with several heterogeneous disease subtypes. They can range from limited muscle or skin involvement to severe, systemic, life-threatening disease. Although the etiology is unknown, some evidence suggests a role for external agents, particularly drugs. Herein, we present a case of a 71-year-old woman with chronic myeloid leukemia who developed imatinib-induced dermatomyositis sine dermatitis. The presentation was predominantly muscular, characterized by proximal muscle weakness and myalgia of the lower limbs, with positive anti-Mi2a antibodies. Spontaneous recovery was observed after drug discontinuation, without the need for immunosuppressive therapy. This is the first confirmed description of an imatinib-induced dermatomyositis sine dermatitis. It reflects the importance of a high awareness from rheumatologists and hematologists to accurately anticipate and identify similar situations.

Is the varying management of incontinence-associated dermatitis due to a lack of understanding of etiology?

Incontinence-associated dermatitis, previously and sometimes still referred to as moisture lesions or moisture damage, is a commonly seen contact dermatitis that is a reactive response of the skin to chronic contact to urine and faecal matter. Understanding the etiology is fundamental to creating a skin care plan and successfully prevention. Systemic reviews and studies have shown that the continued variability in management results from a combination of knowledge base, observation, diagnosis, and product selection. This article aims to improve clinicians' understanding of incontinence-associated dermatitis and its management.

Troxerutin suppress inflammation response and oxidative stress in jellyfish dermatitis by activating Nrf2/HO-1 signaling pathway.

Background: Stomolophus meleagris envenomation causes severe cutaneous symptoms known as jellyfish dermatitis. The potential molecule mechanisms and treatment efficiency of dermatitis remain elusive because of the complicated venom components. The biological activity and molecular regulation mechanism of Troxerutin (TRX) was firstly examined as a potential treatment for jellyfish dermatitis. Methods: We examined the inhibit effects of the TRX on tentacle extract (TE) obtained from S. meleagris in vivo and in vitro using the mice paw swelling models and corresponding assays for Enzyme-Linked Immunosorbent Assay (ELISA) Analysis, cell counting kit-8 assay, flow cytometry, respectively. The mechanism of TRX on HaCaT cells probed the altered activity of relevant signaling pathways by RNA sequencing and verified by RT-qPCR, Western blot to further confirm protective effects of TRX against the inflammation and oxidative damage caused by TE. Results: TE significantly induced the mice paw skin toxicity and accumulation of inflammatory cytokines and reactive oxygen species in vivo and vitro. Moreover, a robust increase in the phosphorylation of mitogen-activated protein kinase (MAPKs) and nuclear factor-kappa B (NF-κB) signaling pathways was observed. While, the acute cutaneous inflammation and oxidative stress induced by TE were significantly ameliorated by TRX treatment. Notablly, TRX suppressed the phosphorylation of MAPK and NF-κB by initiating the nuclear factor erythroid 2-related factor 2 signaling pathway, which result in decreasing inflammatory cytokine release. Conclusion: TRX inhibits the major signaling pathway responsible for inducing inflammatory and oxidative damage of jellyfish dermatitis, offering a novel therapy in clinical applications.

The Prevalence of Incontinence and Its Association With Urinary Tract Infections, Dermatitis, Slips and Falls, and Behavioral Disturbances Among Older Adults in Medicare Fee-for-Service.

PURPOSE: The purpose of this study was to examine the prevalence of urinary (UI), fecal (FI), and dual incontinence (DI) in older adults and their association with urinary tract infections, dermatitis, slips and falls, and behavioral disturbances based on Medicare fee-for-service (FFS) claims data. DESIGN: Retrospective analysis. SUBJECTS AND SETTINGS: Data from administrative claims from the CMS Medicare Limited Data Set (5% sample) for all months in 2018 were reviewed. The analysis was limited to FFS Medicare beneficiaries, with minimum of 3-month enrollment in Parts A and B who were at least 65 years old. This cohort included 1.2 million beneficiaries in the United States. METHODS: We used diagnosis codes to identify members with incontinence and grouped these members into 3 categories (UI only, FI only, and DI). We also divided claims based on 4 sites of care (nursing home, skilled nursing facility, home health, and self- or family care). We then determined the prevalence of (1) urinary tract infections (UTIs), (2) dermatitis, (3) slips and falls, and (4) behavioral disturbances for each type of incontinence. RESULTS: We found that 11.2% of Medicare members had a claims-based diagnosis of incontinence in 2018. On average, those diagnosed with incontinence experienced 5 times more UTIs, 2 times as many dermatitis events, more than twice as many slips and falls, and 2.8 times more behavior disturbances compared to those without an incontinence diagnosis. For those with DI, the prevalence of the 4 outcomes was significantly higher (between 22% and 185%) compared to those with UI only. CONCLUSIONS: Findings show that Medicare beneficiaries diagnosed as incontinent experience a much higher prevalence of UTIs, dermatitis, slips and falls, and behavioral disturbances compared to those without a diagnosis of incontinence. Our results suggest that incontinence may be an important indicator diagnosis for multiple other conditions and, if not well-managed, may challenge the desire for those who are incontinent to age at home.

Prolyl hydroxylase inhibition protects against murine MC903-induced skin inflammation by downregulating TSLP.

Previously, we reported an anti-inflammatory effect of mTORC1 in a mouse model of type 2 skin inflammation. TSLP, one of the epithelial cell-derived cytokines, was upregulated by Raptor deficiency or rapamycin treatment, which was inhibited by dimethyloxalylglycine (DMOG). However, it remains unclear how DMOG regulates TSLP expression and type 2 skin inflammation. In this study, we investigated the protective effect of DMOG on MC903 (calcipotriol)-induced type 2 skin inflammation. Morphological and immunological changes were assessed by H-E staining, flow cytometry and RT-qPCR. DMOG treatment attenuated MC903-induced skin inflammation in a T cell-independent manner. The anti-inflammatory effect of DMOG was accompanied by downregulation of TSLP and IL-33, and supplementation with recombinant TSLP and IL-33 abolished the effect of DMOG. MC903 increased ROS levels in skin tissue, which was prevented by DMOG. Furthermore, the ROS scavenger N-acetylcysteine (NAC) downregulated TSLP and ameliorated MC903-induced skin inflammation, as did DMOG. Finally, the effect of DMOG on ROS and TSLP was reduced by HIF knockdown. These results suggest that DMOG downregulates TSLP and ROS through the HIF pathway, which reduces MC903-induced skin inflammation.

Feed form and perch design do not interact to production performance, gastrointestinal tract traits, behaviour and welfare of laying hens reared in enriched cages.

1. It was hypothesised that perch material and design may affect utility and maintenance energy demand in laying hens, affecting their feed form preferences and daily feed consumption. Accordingly, perch design and feed form on hen performance, gastrointestinal tract functions and some behavioural and welfare-related traits were studied in laying hens (ATAK-S) reared in enriched colony cages from 24 to 40 weeks of age.2. The experiment was a 2 × 2 factorial investigating two perch materials and design (circular steel or mushroom-shaped plastic) and feed form (mash or crumble). A total of 396 hens were randomly assigned to one of the four treatment groups with nine replicates each (11 birds per replicate).3. Except for feeding behaviour and prevalence of foot pad dermatitis at 40 weeks of age, the modification of the perch design did not have a significant effect on the traits examined. Mushroom-shaped plastic perches reduced feeding behaviour (p < 0.01) and the incidence of foot pad dermatitis at 40 weeks of age (p < 0.001).4. Performance traits were not affected by feed form. Intake, final body weight and FCR for crumble-fed laying hens were greater than those fed mash (p < 0.01).5. Hens fed mash had higher (p < 0.01) relative gizzard weights along with lower (p < 0.05) pH values, pancreatic chymotrypsin, amylase and lipase activities (p < 0.05), and duodenal absorption surface areas (p < 0.01). Ultimately, this gave higher protein digestibility (p < 0.05) compared to those receiving crumble.6. In conclusion, in enriched cage rearing systems, mashed feed was preferred over crumble to efficiently maintain productive performance. Compared to circular steel, plastic mushroom-shaped perches were associated with better footpad health and welfare.

Palisaded Neutrophilic Granulomatous Dermatitis, Bowel-Associated Dermatosis-Arthritis Syndrome, and Rheumatoid Neutrophilic Dermatitis.

Neutrophilic dermatosis is a heterogeneous group of inflammatory skin diseases characterized by the presence of a sterile neutrophilic infiltrate on histopathology. Three specific types of neutrophilic dermatoses are reviewed in this article: palisaded neutrophilic granulomatous dermatitis, bowel-associated dermatosis-arthritis syndrome, and rheumatoid neutrophilic dermatitis. The authors review the literature and highlight the clinical and histopathological features, disease pathogenesis, and the association of these conditions with various systemic diseases such as rheumatoid arthritis, inflammatory bowel disease, and others. A multidisciplinary approach is necessary for the diagnosis and management of these inflammatory skin conditions.

Research Note: Welfare and stress responses of broiler chickens raised in conventional and animal welfare-certified broiler farms.

The present study was conducted to assess the animal welfare status of broiler chickens raised in conventional and welfare-certified farms. One conventional farm (30,000 birds/house, 1,488 m2/house, 2 houses) and one animal welfare-certified farm (32,000 birds/house, 1,920 m2/house, 2 houses) were selected to measure productivity, stress responses, and animal welfare indicators in 3 broiler flocks (2 farms/season, n = 6 flocks/farm type) during summer, autumn, and spring. Upon farm visits, body weight, uniformity, and animal welfare indicators (i.e., fecal and feather corticosterone, footpad dermatitis, hock burn, feather dirtiness, and gait score) were measured at 26 d posthatch. Also, moisture, nitrogen, and pH of litter, light intensity, ammonia concentration, and body surface temperature of head, chest, and legs were measured. There was no difference in body weight and uniformity between farm types. Fecal corticosterone concentrations were higher (P = 0.021) in welfare-certified vs. conventional farm, but no significant difference was found in feather corticosterone. Welfare-certified vs. conventional farm had lower percentages of hock burn (P = 0.018), feather dirtiness scores (P = 0.009), and gait score (P = 0.040), and there was no difference in footpad dermatitis. Nitrogen content in litter samples tended to be higher in conventional vs. welfare-certified farms (P = 0.094), and there was no difference in moisture and pH between farm types. Ammonia concentration within the broiler houses was not different between 2 farms. However, animal welfare farm was found to be brighter than conventional farm (P < 0.001). The body surface temperature of head, chest, and legs was not different between farm types. In conclusion, the welfare-certified farm had higher welfare measures, including lower hock burn, feather dirtiness, and gait score, confirming an overall improvement in welfare indicators. However, the observation on the elevated feather corticosterone noted in welfare vs. conventionally raised chickens warrants further studies.

Conjugated Network Supporting Highly Surface-Exposed Ru Site-Based Artificial Antioxidase for Efficiently Modulating Microenvironment and Alleviating Solar Dermatitis.

Solar dermatitis, a form of acute radiation burn that affects the skin, results from overexposure to ultraviolet B (UVB) radiation in strong sunlight. Cell damage caused by the accumulation of reactive oxygen species (ROS) produced by UVB radiation plays an important role in UVB-induced inflammation in the skin. Here, for efficiently scavenging excess ROS, modulating the microenvironment, and alleviating solar dermatitis, a π-conjugated network polyphthalocyanine supporting a highly surface-exposed Ru active site-based artificial antioxidase (HSE-PPcRu) is designed and fabricated with excellent ROS-scavenging, antioxidant, and anti-inflammatory capabilities. In photodamaged human keratinocyte cells, HSE-PPcRu could modulate mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B signaling pathways, prevent DNA damage, suppress apoptosis, inhibit pro-inflammatory cytokine secretion, and alleviate cell damage. In vivo animal experiments reveal the higher antioxidant and anti-inflammatory efficacies of HSE-PPcRu by reversing the activation of p38 and c-Jun N-terminal kinase, inhibiting expression of cyclooxygenase-2, interleukin-6, interleukin-8, and tumor necrosis factor-α. This work not only provides an idea for alleviating solar dermatitis via catalytically scavenging ROS and modulating the microenvironment but also offers a strategy to design an intelligent conjugated network-based artificial antioxidase with a highly surface-exposed active site.

VMAT with DIBH in hypofractionated radiotherapy for left-sided breast cancer after breast-conserving surgery: results of a non-inferiority clinical study.

The purpose of this study was to show the safety of volumetric modulated arc therapy (VMAT) with deep inspiration breath-hold (DIBH) in hypofractionated radiotherapy for left-sided breast cancer after breast-conserving surgery in a clinical setting. Twenty-five Japanese women, aged 20-59 years, who were enrolled in this prospective non-inferiority study received VMAT under the condition of DIBH with 42.4 Gy/16 fractions for whole-breast irradiation (WBI) ± boost irradiation for the tumor bed to show the non-inferiority of VMAT with DIBH to conventional fractionated WBI with free breathing. The primary endpoint was the rate of occurrence of radiation dermatitis of Grade 3 or higher or pneumonitis of Grade 2 or higher within 6 months after the start of radiotherapy. This study was registered with UMIN00004321. All of the enrolled patients completed the planned radiotherapy without interruption. The evaluation of adverse events showed that three patients (12.0%) had Grade 2 radiation dermatitis. There was no other Grade 2 adverse event and there was no patient with an adverse event of Grade 3 or higher. Those results confirmed our hypothesis that the experimental treatment method is non-inferior compared with our historical results. There was no patient with locoregional recurrence or metastases. In conclusion, VMAT under the condition of DIBH in hypofractionated radiotherapy for left-sided breast cancer after breast-conserving surgery can be performed safely in a clinical setting.

Myelodysplasia cutis masquerading as granulomatous dermatitis.

Myelodysplastic syndromes (MDS) are a group of clonal hematopoietic neoplasms resulting from mutations in stem cells. They carry a risk of transformation to acute myeloid leukemia. Cutaneous manifestations of MDS, including myelodysplasia cutis or infiltration by MDS tumor cells, are rare, but significantly associated with increased risk of progression to high-grade myeloid tumors. The clinical and histopathologic differential diagnosis for myelodysplasia cutis includes interstitial granulomatous dermatitis (IGD), a reactive granulomatous dermatitis (RGD) associated with systemic diseases including rheumatologic diseases, and hematologic malignancy like MDS. We report a patient with MDS who presented with myelodysplasia cutis masquerading as IGD both in a clinical and histopathological manner.

Coronavirus disease 2019 pandemic related chondrodermatitis nodularis helicis: the role of masks.

BACKGROUND: Chondrodermatitis nodularis helicis is a benign, but painful inflammatory condition of the ear, characterised by a tender nodule located on the helix or antihelix. This study aimed to investigate the occurrence of chondrodermatitis nodularis helicis associated with the use of coronavirus disease 2019 masks during the pandemic. METHOD: A retrospective single-centre study was performed from February 2020 to February 2022 in the Maxillo-Facial Unit at the University Hospital of Siena, Italy. RESULTS: During the indexed period, 11 patients were affected by chondrodermatitis nodularis helicis. All patients wore a mask for more than 8 hours a day, every day for several months. CONCLUSION: Although there is no certain proof of the correlation between masks and chondrodermatitis nodularis helicis, an increase in the incidence of this condition was highlighted in our single-centre experience in the pandemic period. The prolonged use of coronavirus disease 2019 masks may explain this correlation.
