Abstract
Skin adverse reactions to diabetes medical devices have been reported frequently over recent years. Adhesives attaching glucose sensors and continuous insulin infusion sets to the skin are proven to cause both allergic contact dermatitis and irritant contact dermatitis in patients with diabetes mellitus. Several allergens contained in adhesives and/or parts of medical devices are documented to cause allergic contact dermatitis, with acrylate chemicals being the most common culprit-especially isobornyl acrylate (IBOA), but also 2,2'-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate or cyanoacrylates. Epoxy resin, colophonium and nickel were also identified as causative allergens. However, repetitive occlusion, maceration of the skin and resulting disruption of the skin barrier seem to have an impact on the development of skin lesions as well. The purpose of this study is to highlight the burden of contact dermatitis triggered by diabetes medical devices and to show possible mechanisms responsible for the development of contact dermatitis in a group of diabetic patients.

Abstract
Malignant ulcerating wounds or neoplastic lesions are a considerable burden for patients suffering from advanced cancer. These wounds have no effective treatment and are very difficult to manage. The present review summarizes evidence in support of a hypothesis put forward in anthroposophic medicine, which suggests a beneficial role of resin from the species Larix decidua Mill. [Pinaceae] for treating such wounds. A systematic search strategy was performed using the databases PubMed, EMBASE and SciFinder. The included publications described the chemical composition of this species, as well as in vitro, in vivo, and ex vivo experiments using plant extracts and isolated compounds. The results show that among the phytochemical classes, terpenoids were the major components of this species, especially in the resin. The summarized biological experiments revealed antimicrobial, antioxidant and anti-inflammatory effects, with promising potential for the extracts and isolated compounds. However, the molecular mechanisms and toxicological effects are as of yet not conclusively evaluated. From the data of our study, we can conclude that L. decidua might indeed have a promising potential for the treatment of malignant wounds, but definitive information that can prove its effectiveness is still lacking. We therefore suggest that future efforts should be dedicated to the evaluation of L. decidua resin's therapeutic use considering its antiseptic action and proposed wound healing properties.

Abstract
BACKGROUND Besides being a potential component of (some species of) colophonium, D-limonene is also used as a tackifier in the production of adhesives. Hydroperoxides of limonene are well-known skin sensitizers. OBJECTIVES To show that D-limonene may be present in colophonium-containing but also colophonium-free ("hypoallergenic") adhesives, and that patients suffering from allergic contact dermatitis (ACD) from both types of adhesives might display positive patch test reactions to limonene hydroperoxides in this regard. METHODS Five patients with suspected ACD from adhesives were patch tested to the baseline series (containing limonene hydroperoxides 0.3 and 0.2% pet.), additional series and, if available, to the culprit adhesives. The adhesives labelled as containing colophonium (n = 3) or free from it (n = 2) were analysed with gas chromatography - mass spectrometry (GC-MS) for the presence of D-limonene. RESULTS All five patients sensitised to adhesives had (strong) positive patch test reactions to limonene hydroperoxides. The presence of D-limonene, and/or related components, could be demonstrated in all three colophonium-containing and, surprisingly, also in two colophonium-free ("hypoallergenic") tapes. CONCLUSIONS D-limonene may be present in both regular and "hypoallergenic" adhesives, with limonene hydroperoxides potentially contributing to ACD from such medical devices. The use of fragrance chemicals in adhesives deserves further research.

Abstract
BACKGROUND The number of patients with contact dermatitis from glucose sensors and insulin infusion sets is increasing. Patch testing is challenging because of a lack of information concerning the constituent materials of medical devices. OBJECTIVES To report on products and causes of allergic reactions to glucose sensors or insulin infusion sets over a 5-year period and suggest a short screening series. METHODS Analysis of patch test data from consecutive patients suspected of allergic contact dermatitis (ACD) to glucose sensors and/or insulin infusion sets from 2015-2019. RESULTS Patient numbers increased from 4 to 15 per year; 30/38 (78.9%) were children. In 29 (76.3%), a diagnosis of allergic/probable ACD was established, mostly due to the tapes of the device or allergens in these tapes (n = 23) followed by allergens in the device housing (n = 10). Isobornyl acrylate, abitol, and colophonium were the most common allergens. Information from manufacturers was often difficult to obtain and, if accessible, inadequate. For this reason, the diagnosis was delayed for more than 1.5 years in 12 (31%) patients. CONCLUSIONS The increasing number of patients, mostly children, with ACD from devices used in treatment of type 1 diabetes demonstrates the importance of this problem. Allergies can easily be overlooked, due to the lack of mandatory labeling of the constituent materials of the devices.

Abstract
With more than 350,000 plant species recognized and new species continually being identified, it is not surprising that humans contact plants or plant-containing products daily. The nearly endless list of potential exposures leaves us with a challenging task when attempting to categorize and study potential plant-related irritants and allergens. This article focused on laying a sound framework for understanding some of the more pertinent potential irritants and allergens.

Abstract
Diabetes mellitus is one of the most prevalent chronic diseases in the USA. If uncontrolled, diabetes can lead to devastating complications. Diabetes medications and medical devices largely contribute to the significant financial expense that the disease inflicts on affected individuals and society. Alongside significant economic burden, there are numerous cutaneous adverse effects associated with diabetes medications and medical devices. Despite the large and increasing number of individuals living with diabetes and the wide use of the related medications and medical devices, there is limited literature that comprehensively documents their cutaneous adverse effects. These cutaneous adverse effects are significant as they can worsen glycemic control, increase disease distress, and may increase risk of associated complications. Thus, it is important that providers can recognize these cutaneous adverse effects, identify the culprit agents, and can properly manage them. In this article, we provide a critical review of the cutaneous adverse effects of medications and devices used in the management of diabetes and provide insight into risk factors and prevention and an overview of therapeutic management. An emphasis is placed on clinical recognition and treatment for use of the medical providers who, regardless of practice setting, will treat patients with diabetes.

Abstract
BACKGROUND Colophonium is a natural substance derived from Pineaceae trees. It is used in a wide range of consumer and occupational products because of its tackiness, and is a known sensitizer. OBJECTIVES To analyse the temporal trend of contact allergy to colophonium in north-eastern Italy, and to evaluate the associations with occupations in our geographical area. METHODOLOGY From 1996 to 2016, 27 381 patients with suspected allergic contact dermatitis were patch tested in north-eastern Italy. Individual characteristics were documented by use of a standardized questionnaire in 6 departments of dermatology or occupational medicine. RESULTS The overall prevalence of colophonium sensitization was 1.67%; the prevalence was significantly higher in women (1.75%) than in men (1.49%). No significant differences among departments were observed. We found significant associations between colophonium sensitization and being a student (odds ratio [OR] 4.64; 95% confidence interval [CI]: 1.04-20.6), being a farmer or fishermen (OR 3.63; 95%CI: 1.21-10.84), being a housekeeper (OR 2.02; 95%CI: 1.08-3.77), and being retired (OR 2.06; 95%CI: 1.08-3.92). CONCLUSION Our study showed that contact allergy to colophonium is still relevant in north-eastern Italy. The frequency of sensitization has dropped significantly over a period of 10 years, but students and farmers/fishermen still have sensitization prevalences above 3.5%. Our results are in line with European data.

Abstract
The present opinion deals with the re-evaluation of glycerol esters of wood rosin (GEWR, E 445) when used as a food additive. Regarding GEWR originating from Pinus palustris (longleaf pine) and Pinus elliottii (slash pine), based on the overall toxicity database, and given the absence of reproductive and developmental toxicity data, the Panel concluded that the current acceptable daily intake (ADI) of 12.5 mg/kg body weight (bw) per day for GEWR (E 445) as established by the Scientific Committee on Food (SCF) in 1994 should be temporary pending the provision of such data. This assessment is restricted to GEWR derived from P. palustris (longleaf pine) and P. elliottii (slash pine) and with a chemical composition in compliance with GEWR used in the toxicological testing. The Panel concluded that the mean and the high exposure levels (P95) of the brand-loyal refined exposure scenario did not exceed the temporary ADI in any of the population groups from the use of GEWR (E 445) as a food additive at the reported use levels. For GEWR originating from Pinus halepensis and Pinus brutia, the Panel noted that concentrations of the fractions of 'glycerol monoesters', 'free resin acids' and 'neutrals', which are considered to be of particular toxicological relevance, are not known; therefore, the evaluation of chemical equivalence with GEWR originating from P. palustris (longleaf pine) and P. elliottii (slash pine) is not possible; no data on stability were available; no toxicological data were available. Therefore, the Panel concluded that a safety assessment of GEWR originating from P. halepensis and P. brutia could not be performed. The Panel recommended the European Commission to consider an update of the definition of GEWR (E 445) in the EU specifications. It should be indicated that GEWR (E 445) (i) contain, besides the mentioned glycerol di- and triesters, a residual fraction of glycerol monoesters, and (ii) contain residual free resin acids and neutrals (non-acidic other saponifiable and unsaponifiable substances).

Novel aqueous oil-in-water emulsions containing extracts of natural coniferous resins are strongly antimicrobial against enterobacteria, staphylococci and yeasts, as well as on bacterial biofilms. J Appl Microbiol 2017; 124:136-143.

Abstract
AIMS The aim of this study was to examine the antimicrobial properties of novel aqueous natural rapeseed oil/saline emulsions containing different soluble components of spruce resin. METHODS AND RESULTS The composition of aqueous resin emulsions was analysed by GC-MS and their antimicrobial properties were studied with challenge tests and with turbidometric assays. The emulsions were strongly antimicrobial against common Gram-positive and Gram-negative bacteria (including MRSA) as well as common yeasts. Furthermore, they inhibited the biofilm formation and eradicated the microbial biofilms on tested microbes. Characteristic for the emulsions was the presence of oxidized resin acids. Other main components present in emulsions, such as lignans and coumaric acids, were not antimicrobial, when tested separately. CONCLUSIONS The results indicated that the oxidized resin acids were the antimicrobial components in the emulsions. Also, there appears to be a stoichiometric relationship between the number of resin acid molecules and the number microbe cells in the antimicrobial action. SIGNIFICANCE AND IMPACT OF THE STUDY The fact that these solutions do not contain abietic acid, which is the main allergenic compound in resins, suggests that these solutions would be suitable, well-tolerated antimicrobials for various medical applications. The aqueous formulation will also allow the expansion of the use of these emulsions in from medical applications to the food preservatives and disinfectants.

Abstract
Introduction Fluoride varnish is an effective prevention intervention for caries in young children. Its routine use in clinical care is supported by meta-analyses and recommended by clinical guidelines, including the US Preventive Services Task Force (B rating). This report is the first prospective systematic assessment of adverse events related to fluoride varnish treatment in young children. Methods We determined the incidence of adverse events related to fluoride varnish treatment in 3 clinical trials on the prevention of early childhood caries, conducted under the auspices of the Early Childhood Caries Collaborating Centers, an initiative sponsored by the National Institute of Dental and Craniofacial Research. Each trial incorporated use of fluoride varnish in its protocol and systematically queried all children’s parents or legal guardians about the occurrence of acute adverse events after each fluoride varnish treatment. Results A total of 2,424 community-dwelling, dentate children aged 0 to 5 years were enrolled and followed for up to 3 years. These children received a cumulative total of 10,249 fluoride varnish treatments. On average, each child received 4.2 fluoride varnish treatments. We found zero fluoride varnish–related adverse events. Conclusion Fluoride varnish was not associated with treatment-related adverse events in young children. Our findings support its safety as an effective prevention intervention for caries in young children.

Abstract
Two resin acids, abietic acid (AA) and dehydroabietic acid (DHAA), in cosmetics may cause allergy or toxicoderma, but remain inaccurately investigated due to their lability. In this work, an accurate, sensitive, efficient and convenient method, utilizing the ultrasonic-assisted closed in-syringe extraction and derivatization (UCSED) prior to high performance liquid chromatography (HPLC) coupled with fluorescence detection (FLD) and on-line tandem mass spectra (MS/MS), has been developed. Analytes are extracted by acetonitrile (10/1, v/m) in a sealed syringe under safe condition (60°C; 15 min; nitrogen atmosphere) and then in-syringe derivatized by 2-(2-(anthracen-10-yl)-1H-naphtho[2,3-d]imidazol-1-yl) ethyl-p-toluenesulfonate (ANITS) (8-fold, 93°C, 30 min, DMF as co-solvent, K2CO3 as catalyst). In UCSED, derivatization contributes to increase both analytical sensitivity and stability of analytes. Excellent linearity (r2≥0.9991) is achieved in wide range (75-3000 ng/mL (AA); 150-4500 ng/mL (DHAA)). Quite low detection limits (AA: 8.2-10.8 ng/mL; DHAA: 19.4-24.3 ng/mL) and limits of analyte concentration (LOAC) (AA: 30.0-44.5 ng/mL; DHAA: 70.9-86.7 ng/mL) ensure the trace analysis. This method is applied to the analysis of cosmetic samples, including depilatory wax strip, liquid foundation, mascara, eyeliner, eyebrow pencil and lip balm. No additional purification is required and no matrix effect is observed, demonstrating obvious advantages over conventional pretreatment such as solid phase extraction (SPE). Accuracy (RE: -3.2% to 2.51%), precision (RSD: 1.29-2.84%), recovery (95.20-103.63%; 95.51-104.22%) and repeatability (<0.23%; <2.87%) are significantly improved. Furthermore, this work plays a guiding role in developing a reasonable method for labile analytes.

Abstract
BACKGROUND Little is known about the use of prick tests with chemicals in diagnosing occupational diseases. OBJECTIVE To evaluate the use of prick tests in the diagnosis of occupational contact urticaria, asthma and rhinitis caused by chemicals (undertaken at the Finnish Institute of Occupational Health). MATERIAL AND METHODS We retrospectively reviewed the patient and test files for the period 1 January 1991 to 31 May 2011. Prick tests were performed with chemical solutions and human serum albumin (HSA)-chemical conjugates. RESULTS Positive prick test reactions to isocyanate-HSA conjugates were associated with isocyanate-specific IgE in all 20 patients, and 17 patients had a relevant occupational disease. Positive reactions to chloramine-T-HSA conjugates in 10 patients also indicated the presence of specific IgE, although occupational diseases were not always diagnosed. Eleven of 17 patients with positive reactions to persulfate solutions were diagnosed with an occupational disease. Methacrylates, colophonium-related substances, amine hardeners, ethanolamines, glutaraldehyde, glyoxal, pyrocatechol and ammonium thioglycolate did not elicit any relevant prick test reactions. No generalized reactions were detected. CONCLUSION Prick tests can be safely used for diagnosing contact urticaria, asthma and rhinitis caused by isocyanates, chloramine-T, persulfates, and chlorhexidine, but the results should be carefully interpreted and related to clinical symptoms and other diagnostic tests.

Abstract
DATA SOURCES The Cochrane Oral Health Group's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, CINAHL, LILACS and BBO, ProQuest Dissertations and Theses, Web of Science Conference Proceedings and ClinicalTrials.gov databases were searched. Reference lists of identified articles were also scanned for relevant papers. Study authors were contacted for additional information. STUDY SELECTION Randomised or quasi-randomised controlled trials using or indicating blind outcome assessment that compared fluoride varnish to placebo or no treatment for at least one year were included. Risk of bias assessment was undertaken. DATA EXTRACTION AND SYNTHESIS Study assessment and data extraction was carried out independently by at least two reviewers. The primary measure of effect was the prevented fraction, that is the difference in mean caries increments between the treatment and control groups expressed as a percentage of the mean increment in the control group. The caries increments nearest to three years were used from each included study. Random-effects meta-analyses were performed where data could be pooled. Potential sources of heterogeneity were examined in random-effects meta-regression analyses. Adverse effects information was collected from the included trials. RESULTS Twenty-two trials (12,455 participants) were included. Thirteen trials were included in the permanent tooth surfaces meta-analysis, the pooled D(M)FS prevented fraction estimate comparing fluoride varnish with placebo or no treatment was 43% (95% confidence interval (CI) 30% to 57%; P < 0.0001). There was substantial heterogeneity, confirmed statistically (P < 0.0001; I(2) = 75%), however this body of evidence was assessed as of moderate quality. Ten trials contributed to the meta-analysis of primary teeth, the pooled d(e/m)fs prevented fraction estimate was 37% (95% CI 24% to 51%; P < 0.0001), there was some heterogeneity (P = 0.009; I(2) = 59%) this evidence was assessed as of moderate quality. No significant associations in either dentitions were found with baseline caries severity, background exposure to fluorides, application features such as prior prophylaxis, concentration of fluoride or frequency of application. There was little information concerning possible adverse effects or acceptability of treatment. CONCLUSIONS The conclusions of this updated review remain the same as when it was first published. The review suggests a substantial caries inhibiting effect of fluoride varnish in both permanent and primary teeth; however the quality of the evidence was assessed as moderate, as it included mainly high risk of bias studies, with considerable heterogeneity.

Abstract
Evidence of intense nanoparticle generation from a low power (45W) flux soldering unit is presented. This is a familiar device often used in daily life, including home repairs and school electronic laboratories. We demonstrate that metal-containing nanoparticles may reach high concentrations (ca. 10(6) particles/cm(3)) within the breathing range of the operator, with initial size distributions centered at 35-60nm The morphological and chemical analysis of nanoparticle agglomerates collected on TEM grids and filters confirms their multiparticle structure and the presence of metals.

Abstract
Cytochrome P450 enzymes exhibit a tremendous potential for biotechnological applications due to their ability to introduce oxygen into non-activated carbon atoms. Their catalytic diversity is complemented by a broad substrate range covering many natural compounds. Especially the functionalization of terpenoids by P450s becomes increasingly interesting due to the diverse biological effects of these compounds. The bacterial CYP105A1 from Streptomyces griseolus was recently identified to carry out a one-step hydroxylation of several abietane-type resin acids. In this work, a whole-cell system for CYP105A1 with its heterologous electron transfer proteins Arh1 and Etp1(fd) from Schizosaccharomyces pombe was designed in Escherichia coli JM109 cells. Additionally, an enzyme-coupled cofactor regeneration system was integrated by co-expression of alcohol dehydrogenase from Lactobacillus brevis. In order to overcome mass transfer limitations of substrate into the cell, different agents were tested towards their permeabilizing activity on the E. coli membrane. The peptide antibiotic polymyxin B proved to be the most effective permeabilizer. After optimising the expression and conversion conditions, the cells were able to completely convert 200 μM of abietic acid into 15-hydroxyabietic acid within 2 h, exhibiting an initial conversion rate of 125 μM/h. These results demonstrate the high potential of this whole-cell system for the synthesis of functionalized resin acid diterpenoids.

Abstract
Over the past years, hydrocolloid dressings have been introduced routinely in the treatment of various types of wounds. They provide a moist environment promoting autolytic debridement, and stimulate angiogenesis. However, long-term application often leads to inflammation of the skin in the immediate area of the ulcer, causing irritant dermatitis in many cases, but sometimes also leads to contact sensitization. A 32 year-old woman burnt herself by an iron, and presented to our clinic and was treated with Duoderm extrathin®. Nine days later, she again presented with an erythematous oozing patch with edema, and allergic contact dermatitis was suspected. A patch test (TRUE test) was performed and a positive reaction to colophonium was obtained. Duoderm extrathin® contains hydrogenated rosin (colophonium) as the tackifying agent, so we could diagnose this case as allergic contact dermatitis due to the hydrogenated rosin in Duoderm extrathin®. We report another case of allergic contact dermatitis due to Duoderm extrathin® in a 32 year-old woman.

Abstract
We report on the first case identifying colophony as a hidden allergen in declared acrylate-based conductive and adhesive foam electrodes. This surgery was followed by continuous electrocardiogram monitoring. The patch tests showed strong positive reactions to colophony. The presence of colophony on the electrocardiogram electrodes was not declared, but it was used in the soldering process during manufacture, which deposited a small amount that was sufficient to induce sensitization.

Abstract
Considering the widespread use of colophony-containing epilating products and the frequency of sensitization to colophony, it is somewhat surprising that reports of allergic contact dermatitis from these products are so infrequent. Reactions to colophony can be severe, and they may present even after initial exposure (primary sensitization). Consequently, health care practitioners should be aware of potential colophony-induced allergic contact dermatitis in patients exposed to epilating products. Patch testing with commercially available colophony unmodified rosins often fails to detect reactions to the modified-rosin derivatives found in the actual epilating products. Therefore, the evaluation of colophony allergy may require testing with the patient's own products as well as additional modified colophony rosins. We describe a case of allergic contact dermatitis caused by colophony found in an epilating product.

Abstract
This study concerns a 69-year-old female patient with a longstanding history of venous ulcerations on both lower legs and multiple sensitivities, who developed eczematous lesions with the hydrocolloid dressing Combiderm (Convatec Ltd., a Bristol-Myers Squibb division, Ickenham, Middlesex, UK). Epicutaneous tests were positive to this dressing and to a modified colophonium derivative, i.e. glyceryl rosinate, however not to the unmodified colophonium from the standard series. A review of the literature showed several case reports about sensitization to similar hydrocolloids being distributed under various brand names in different countries and which contain the pentaerythritol ester of the hydrogenated rosin as the tackifying agent. Some of the patients described did, while others did not, react to colophonium but only to a modified derivative. In our patient, the reaction to glyceryl rosinate most probably represent cross-sensitivity with the modified colophonium derivative used in Combiderm, the presence (but not the exact nature) of which was showed by the company. In patients where allergic contact dermatitis from hydrocolloid dressings is strongly suspected and colophonium tests negatively, patch testing to modified colophonium derivatives should therefore be performed. As the complete composition of wound dressings is most often unknown, we urgently advocate legal requirements for labelling of those and in fact all medically used devices.
