Analysis of risk factors for contact dermatitis in patients with PICC catheterization

Objective To investigate the risk factors for contact dermatitis in patients with peripherally inserted central catheter (PICC) catheterization. Methods A total of 244 patients with PICC catheterization admitted in the Venous Catheter Nursing Outpatient of Affiliated Hospital of Nanjing University of TCM from June to August 2016 were selected using convenience sampling. A prospective study was performed on those patients for general information, PICC catheter information, PICC care information and contact dermatitis development information. SPSS 21.0 was used to analyze the date. Results A number of 24 patients were observed to have contact dermatitis with an incidence of 9.84%. Single factor analysis showed that gender, age, allergy, dressing type and catheter material correlated to the development of contact dermatitis with PICC. The differences were statistically significant (P<0.05) . Multiple factor logistic regression analysis showed that the gender[OR=2.721, 95%CI (1.059-6.994) , P=0.038], allergy[OR=5.846, 95%CI (2.030-16.833) , P=0.001]and dressing type[OR=4.055, 95%CI (1.472-11.169) , P=0.007]were risk factors of contact dermatitis in patients with PICC catheterization. Conclusions For PICC catheterization patients, effective preventive measures aiming at risk factors can reduce the occurrence of contact dermatitis with PICC.

Prevalence and risk factors of contact dermatitis among clothing manufacturing employees in Beijing: A cross-sectional study.

Little is known about the epidemiology of contact dermatitis (CD) in the Chinese clothing industry. This study aimed to investigate the prevalence and some risk factors of contact dermatitis among clothing manufacturing employees in Beijing.This cross-sectional study was conducted by interview using self-administered questionnaires and skin examination between May and August in 2016. Five-hundred twenty-nine employees who had worked at sewing, ironing, and as managers at 12 clothing manufacturing factories were studied.The overall 1-year prevalence of CD among the clothing employees was 28.5% (151/529 employees), with significantly higher prevalence among ironing workers (50%) and sewers (31.7%) compared with managers (12.7%; P < 0.001, n = 529). A significant association was noticed between the 1-year prevalence of CD and types of occupation (sewers and ironing workers versus managers, respectively), exposure to garment materials (leather and feather), dry skin, allergic rhinitis, age, and smoking.Among employees in Chinese clothing industry, sewers and ironing workers had a higher 1-year prevalence of CD than managers. It is noteworthy that exposure to leather and feather materials and the types of manual work are associated with CD, as well as dry skin and allergic rhinitis.

Analysis of risk factors for contact dermatitis in pig farm workers

To investigate the risk factors for contact dermatitis in pig farm workers. The cross-sectional questionnaire survey and on-site survey were conducted in pig farms raising more than 50 pigs in a county of Fujian Province, China. The study subjects were grouped based on different factors. The incidence rate was compared between groups by statistical analysis. Of 302 subjects, 70 (23.18%) had contact dermatitis. There was a significant difference in the prevalence of contact dermatitis between the subjects in direct contact with commercially available pannage and those in indirect contact (χ(2) = 14.552, P < 0.01). Region, season, farm scale, brand of pannage, and allergic history were not influential factors for contact dermatitis (P > 0.05 for all). Direct contact with commercially available pannage is closely associated with contact dermatitis in pig farm workers.

Potential risk factors associated with contact dermatitis, lameness, negative emotional state, and fear of humans in broiler chicken flocks

The objectives of this study were to 1) identify determinants of poor welfare in commercial broiler chicken flocks by studying the associations between selected resource-based measures (RBM, potential risk factors), such as litter quality and dark period, and animal-based welfare indicators (ABM), such as foot pad dermatitis and lameness, and 2) establish the breadth of effect of a risk factor by determining the range of animal welfare indicators associated with each of the risk factors (i.e., the number of ABM related to a specific RBM). Eighty-nine broiler flocks were inspected in 4 European countries (France, Italy, the United Kingdom, and the Netherlands) in a cross-sectional study. The ABM were contact dermatitis (measured using scores of foot-pad dermatitis and hock burn, respectively), lameness (measured as gait score), fear of humans (measured by the avoidance distance test and the touch test), and negative emotional state (measured using qualitative behavior assessment, QBA). In a first step, risk factors were identified by building a multiple linear regression model for each ABM. Litter quality was identified as a risk factor for contact dermatitis. Length of dark period at 3 wk old (DARK3) was a risk factor for the touch test result. DARK3 and flock age were risk factors for lameness, and the number of different stockmen and DARK3 were risk factors for QBA results. Next, the ABM were grouped according to risk factor and counted. Then, in a second step, associations between the ABM were investigated using common factor analysis. The breadth of a risk factor's effect was judged by combining the number (count) of ABM related to this factor and the strength of association between these ABM. Flock age and DARK3 appeared to affect several weakly correlated ABM, thus indicating a broad range of effects. Our findings suggest that manipulation of the predominant risk factors identified in this study (DARK3, litter quality, and slaughter age) could generate improvements in the related ABM and thereby enhance the birds’ overall welfare status.

Contact dermatitis caused by ambulatory blood pressure monitoring

A 63-year-old housewife who had diabetes came to the outpatient clinic for evaluation of labile hypertension. She had undergone a total thyroidectomy 8 years earlier to treat papillary thyroid cancer. She had no history of allergy to any medicine or food. Twenty-four-hour ambulatory blood pressure monitoring was done. After this test, she developed a pruritic erythematous patch on her upper arm, which had been in contact with the blood pressure cuff (Fig. 1). Contact dermatitis after ambulatory blood pressure monitoring has not been reported. She complained markedly about this unexplained complication, which improved after treatment with antihistamines and topical steroid cream. Figure 1 Pruritic erythematous patch on upper arm. (A) Lateral side. (B) Medial side. Contact dermatitis, a common problem in clinical practice, is defined as an inflammatory reaction in response to substances that come in contact with the skin. There are multiple risk factors for developing contact dermatitis. Extrinsic factors include low-humidity, hot, or occlusive environments and occupations that decrease the protective barrier of the skin, including hairdressers, construction workers, health care workers, agricultural workers, and cleaners. Intrinsic factors include Asian skin, which is more reactive than white or black skin, female sex, older age, and a history of atopic dermatitis. We suggest a careful explanation of this possible effect from a common clinical test, especially to patients with risk factors for contact dermatitis.

Concise guidance: diagnosis, management and prevention of occupational contact dermatitis

Occupation is an important risk factor for contact dermatitis that presents in adulthood. Occupational contact dermatitis often has significant adverse effects on quality of life and the long-term prognosis is poor unless workplace exposures are addressed. The condition often presents to general practitioners, physicians or dermatologists who will be responsible for facilitating management of the workplace issues in the event that an occupational health service is not accessible. This concise guidance summarises three sets of guidance from the Occupational Health Clinical Effectiveness Unit, the British Occupational Health Research Foundation and the British Association of Dermatologists respectively. It is aimed at physicians in primary and secondary care, covering the clinical aspects of case management but also drawing attention to the important actions they should take to address the workplace issues, either in liaison with an occupational health provider or in the absence of occupational health input.

Occupational dermatoses in restaurant, catering and fast-food outlets in Singapore

The restaurant industry is a rapidly growing sector in Singapore and workers in this industry are trained in culinary skills but not on recognition of safety and health hazards and their control measures. Anecdotal clinical evidence has suggested an increased prevalence of occupational dermatoses among restaurant workers. To determine the prevalence and risk factors for contact dermatitis and burns among restaurant, catering and fast-food outlet (FFO) staff. Workers were interviewed and then clinical examination and patch and/or prick tests were conducted in selected individuals. In total, 335 of 457 workers (73% response) were interviewed and 65 (19%) had occupational dermatitis or burns and were examined. Of these, contact dermatitis was the commonest diagnosis, with a 12-month period prevalence of 10% (35 workers) and 3-month period prevalence of 8% (26 workers). All 35 workers had irritant contact dermatitis (ICD) and there were no cases of allergic contact dermatitis. The adjusted prevalence rate ratios of risk factors for ICD were 2.78 (95% CI 1.36-5.72) for frequent hand washing >20 times per day, 3.87 (95% CI 1.89-7.93) for atopy and 2.57 (95% CI 1.21-5.47) for contact with squid. The 3-month period prevalence for burns was 6% (20 workers). Ten workers had other occupational dermatoses such as work-related calluses, paronychia, heat rash and allergic contact urticaria to prawn and lobster. ICD and burns are common occupational skin disorders among restaurant, catering and FFO workers.

Home gardening may be a risk factor for contact dermatitis to Alstroemeria

Background Occupational allergy among florists and people who work in cut flower production of Alstroemeria cultivars (Peruvian lily or Inca lily) has been previously reported. The allergen involved in sensitization is tulipalin A (alpha-methylene-gamma-butyrolactone). Case report We describe the case of a 65-year-old woman who developed severe dermatitis on her right thumb, index and middle fingers and less severe dermatitis on her left palm and front of forearm with occasional itching of the neck and face after taking up home gardening activities, including cutting flowers such as Alstroemeria. Methods The patient and three healthy individuals were submitted to epicutaneous tests with the European standard series, the plant series, and stem portions of three suspected ornamental plants ( Alstroemeria, Lilium and Zantedeschia), garlic, and onion. Results Patch tests performed in our patient, revealed an extreme reaction (+ + +) to Alstroemeria and alpha-methylene-gamma-butyrolactone, a strong reaction (+ +) to propolis and wood tar mix, a weak reaction (+) to balsam of Peru, an irritant reaction to garlic and negative results to diallyl disulfide and the other components investigated. Patch tests performed in the healthy individuals revealed negative. Conclusions We stress the importance of Alstroemeria as a cause of allergic contact dermatitis not only in workers involved in the flower trade, but also in other people that come into contact with this plant in their leisure activities.
