RESUMEN
Chronic pruritus (itch lasting ≥6 weeks) is a bothersome chief complaint that may present in a broad variety of diseases. Most itch-causing diagnoses fit into 1 of 5 categories (inflammatory, secondary to systemic disease, neuropathic, chronic pruritus of undetermined origin, and psychogenic itch) and this broad differential can be narrowed using key findings in the history and physical. In this article, we discuss which key findings are most pertinent for narrowing this differential and guiding further workup and treatment, as well as how to treat many itchy conditions.

INTRODUCTION: Calls to poison control about exposure to household cleaners have increased during the COVID-19 pandemic. This dynamic may reflect increased exposure from public health efforts as well as health misinformation shared on social media. METHODS: We analyzed the dynamics of calls to the Regional Center for Poison Control and Prevention serving Massachusetts and Rhode Island (MARI PCC) and tweets discussing treating COVID-19 with house cleaners from January 20, 2020 to May 5, 2020. We obtained publicly available tweets discussing the use of household cleaners to "cure COVID" from the same time period with geographic co-ordinates indicating that they were emitted from the Greater Boston Area. RESULTS: Our main finding is that public health efforts were followed by a sustained increase in calls after March 15, 2020 (10 ± 2 calls per day before to 15 ± 2.5 after) while misinformation on social media was associated with intermittent spikes in calls. Overall, calls significantly increased during the study period by 34% as compared to the previous 8 years, mostly reporting unintentional ingestions with no serious effects. The daily volume of tweets and retweets was significantly correlated with daily call rates to MARI PCC for the surrounding 7-10 days. CONCLUSIONS: Health misinformation on social media about using household cleaning agents to treat COVID-19 and public health efforts lead to different dynamics in PCC calls. Public health efforts were followed by a sustained increase in calls after March 15, 2020 while misinformation on social media was followed by intermittent spikes in calls. This analysis is the first to link the geospatial dynamics of social media and public health interventions to poison center calls about exposure to household cleaners.

INTRODUCTION: Biofilm in chronic wounds impedes the wound healing process. Each biofilm has differing characteristics requiring a multifaceted approach for removal while maintaining a surrounding environment conducive to wound healing. OBJECTIVE: In this study, 3 of the components in a wound cleanser are tested to determine synergy in eradicating biofilms of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa in vitro. MATERIALS AND METHODS: The 3 components assessed for synergy were ethylenediamine tetraacetic acid sodium salts (EDTA), vicinal diols (VD; ethylhexylglycerin and octane-1,2-diol), and polyhexamethylene biguanide (PHMB). Each component was assessed individually and in combination while dissolved in a base solution. The Calgary assay method was used for biofilm growth and treatment. Kull Equation analysis for synergy was conducted using viable count results. RESULTS: Synergy is defined as the interaction of components to produce a combined effect greater than the sum of their separate effects. The base solution containing all 3 components (EDTA, VD, and PHMB) reduced biofilm viability by more than 5 logs, demonstrating statistically significant synergy. The 3 components tested individually in the base solution resulted in the following: EDTA did not reduce bacteria viability; VD reduced viability by about 1 log; and PHMB reduced P aeruginosa viability by about 2.5 logs and MRSA viability by about 4 logs. Of importance, the MRSA biofilm failed to regrow in the recovery plates after combined treatment, indicating complete elimination of the biofilm bacteria. CONCLUSIONS: The experimental and calculated results indicate the 3 components (VD, EDTA, and PHMB) when used together act synergistically to eradicate MRSA and P aeruginosa biofilms in vitro.

BACKGROUND: To compare the efficacy between Johnson's baby shampoo top-to-toe (No More Tears formula) and OCuSOFT Lid Scrub Original Foaming Eyelid Cleanser (OSO) in patients with grade 2 meibomian gland dysfunction (MGD). METHODS: Sixty participants with grade 2 MGD were enrolled and analyzed based on intention to treat basis in a prospective, randomized, single-blind trial for eye scrub using either diluted baby shampoo or OSO. The data collection included the Ocular Surface Disease Index (OSDI) questionnaire, compliance, and complications. The eye examinations were according to the Tear Film and Ocular Surface Society at baseline and at post-treatment weeks 4 and 12. RESULTS: The mean (±SD) age of the 60 patients who presented with grade 2 MGD was 48.0â±â13.8 years and 75.0% were females. The OSDI scores of these participants between pre-treatment and post-treatment weeks 4 and 12 improved significantly in both groups (all Pâ<â.001). The mean (±SD) differences of the improvement of OSDI score from baseline were not statistically significantly different between the baby shampoo and OSO groups at post-treatment weeks 4 and 12 (Pâ=â.57 and Pâ=â.54, respectively). The compliance and complications were also not statistically significant between the 2 groups. CONCLUSIONS: Eyelid scrub using either baby shampoo or OSO and warm compresses could significantly reduce eye irritability and uncomfortable symptoms in grade 2 MGD patients. In this study, the efficacy, compliance, and complications between the 2 groups were not statistically significantly different.

BACKGROUND/OBJECTIVES: Epidermolysis bullosa (EB) comprises a group of inherited skin blistering diseases. There is currently no cure, and management includes skin protection and prevention of infection. To date, there has been no systematic investigation of home skin care practices among EB patients on a multicenter scale. METHODS: This cross-sectional, observational study included data collected from patients with EB enrolled in the Epidermolysis Bullosa Characterization and Clinical Outcomes Database (EBCCOD) who provided answers to a patient-directed questionnaire between January 1, 2017, and December 31, 2017. RESULTS: Of 202 respondents, 130 (64.4%) had dystrophic EB, 51 (25.2%) had EB simplex, 21 (7.4%) had junctional EB, 3 (1.5%) had Kindler syndrome, and 3 (1.5%) had an unspecified subtype. Seventy-eight patients reported cleansing in plain water only (39%). Of those who used an additive in their cleansing water, 75 (57%) added salt, 71 (54%) added bleach, 36 (27%) added vinegar, and 34 (26%) endorsed the use of an "other" additive (multiple additives possible). Reported concentrations of additives ranged widely from 0.002% sodium hypochlorite and 0.002% acetic acid solutions, which are thought to have negligible effects on microbes, to 0.09% sodium hypochlorite and 0.156% acetic acid, concentrations shown to be cytotoxic. One hundred eighty-eight patients answered questions regarding topical product use (93%). Of those, 131 reported topical antimicrobial use (70%). Mupirocin and bacitracin were the most commonly reported topical antibiotics (59, 58 [31.4%, 30.9%], respectively). CONCLUSIONS: These findings highlight the variety of skin care routines and frequent use of topical antimicrobials among EB patients and have potential implications for antibiotic resistance. The reported range of bleach and vinegar additives to cleansing water, including cytotoxic concentrations, emphasizes the need for clear and optimized skin cleansing recommendations.

BACKGROUND: Xerosis is common among patients with Kaposi's sarcoma (KS). The aim of our study was to evaluate the efficacy of a detergent containing dihydroavenanthramide D 5% combined with a moisturizer containing 1% of menthol for the treatment of chronic pruritus associated with xerosis in elderly KS patients. METHODS: We conducted a prospective, open-label, intra-individual, right/left comparative study. During the 4-week treatment study, patients used the test products on the right lower limb, and a basic skin cleanser plus basic cream on their left lower limb, in a predefined protocol. A 10 cm visual analogue scale (VAS), the hydration index (HI) of the stratum corneum and the overall dry skin score (ODSS) were used to assess pruritus and xerosis severity on admission, at 2 and 4 weeks. RESULTS: Thirty patients (24 males, 6 females, mean age: 76.6±6.8 years) were enrolled. At the end of 4 weeks, the mean pruritus VAS score declined from 4.2±2.2 to 1.7±1.4 on the right side, and from 4.2±2.2 to 2.3±1.5 on the left side. The HI score increased from 25.6±15.0 to 46.1±12.3 on the right side, and from 26.0±15.2 to 35.4±12.6 on the left side. Differences between the right and left limbs were significant for VAS score (P=0.0064), HI (P<0.0001) and ODSS values (P=0.0049). There was no adverse reaction to the test products. CONCLUSIONS: Daily use of a detergent containing dihydroavenanthramide D 5% combined with a moisturizer containing 1% of menthol improves chronic pruritus associated with xerosis in elderly adults with KS.

Introduction: Acne vulgaris is a highly prevalent skin condition that can adversely affect the quality of life. Acne-predisposed skin is in a state of subclinical inflammation leading to skin barrier dysfunction. A multi-center cohort study was designed to evaluate clinical efficacy and safety of twice daily facial cleansing using an oscillatory sonic brush, acne brush head, and cleansing gel for 4 weeks. Methods: Subjects with mild-to-moderate acne and acne-prone skin used the cleansing regime after which they applied the skin care products they routinely used. Physician-assessed skin condition comparing baseline versus week 4 using the FDA/IGA scale and subject satisfaction with cleansing efficacy and handling properties of the regime were scored during the last visit. Results: Forty-six subjects completed the study. Physician-scored skin condition showed a statistically significant improvement in FDA/IGA scores and a significant reduction of inflammatory and non-inflammatory lesions comparing baseline versus 4 weeks. Thirty-five (76.0%) subjects had cleared or almost cleared. Subjects similarly assessed their skin to be improved. Conclusion: Both the physician and subject scores revealed the gentle cleansing routine using the sonic brush to be effective reducing the number of acne lesions, improving skin condition. No adverse events were reported during the study period. The cleansing regime may offer an attractive, safe option for maintenance and treatment of subjects with mild-to-moderate acne and acne-prone skin. J Drugs Dermatol. 2019;18(11):1140-1145.

Skin exposures are common during cleaning activities, and may contribute to the overall body burden. Cleaning products may contain irritants such as monoethanolamine (MEA) and diethanol amine (DEA). The significance of the skin exposure route is unknown, as no estimates for MEA skin permeation are available. We used in vitro flow-through diffusion cells with excised fresh human skin to measure skin permeation, and assessed skin damage with histological methods. MEA(aq) by itself (2%) or as a constituent in cleaning products (0.25% working solution) did not permeate after 1 h or 24 h of exposure. MEA(aq) (10%) did not permeate skin after 1 h but after 24 h with a delay (Tlag; 7 h) and a moderate permeation rate (J; 26.6 µg/cm2/h). MEA permeation rate was 20-fold greater (544 µg/cm2/h) and » of the time lag (1.5 h) when applied as undiluted cleaning product (13% MEA) compared to 10% MEA(aq). DEA in cleaning products did not permeate skin after 24 h. MEA and DEA produced skin irritations at low concentrations (1% MEA) and severe skin irritations when tested as a constituent in cleaning products. Absorption increased from 0 to 3% after 24 h to 14-29% after 88 h of MEA exposure, and is likely explained by the increased damage of the skin barrier. Limitations of this study are the low number of skin donors (N = 5) available. Our results demonstrate that topically applied MEA permeates across human skin relatively slowly and not below 5% while relatively extensively as a constituent of a commercial cleaning product.

INTRODUCTION: The aim of this study was to systematically review the evidence on the cleaning and disinfection of root canals and the healing of apical periodontitis when ultrasonic irrigant activation is applied during primary root canal treatment of mature permanent teeth compared with syringe irrigation. METHODS: An electronic search was conducted of the Cochrane Library, Embase, LILACS, PubMed, SciELO, and Scopus databases using both free-text key words and controlled vocabulary. Additional studies were sought through hand searching of endodontic journals and textbooks. The retrieved studies were screened by 2 reviewers according to predefined criteria. The included studies were critically appraised, and the extracted data were arranged in tables. RESULTS: The electronic and hand search retrieved 1966 titles. Three clinical studies and 45 in vitro studies were included in this review. Ultrasonic activation did not improve the healing rate of apical periodontitis compared with syringe irrigation after primary root canal treatment of teeth with a single root canal. Conflicting results were reported by the in vitro microbiological studies. Ultrasonic activation was more effective than syringe irrigation in the removal of pulp tissue remnants and hard tissue debris based on both clinical and in vitro studies. Ultrasonic activation groups were possibly favored in 13 studies, whereas syringe irrigation groups may have been favored in 3 studies. CONCLUSIONS: The level of the available evidence was low, so no strong clinical recommendations could be formulated. Future studies should focus on the antimicrobial effect and healing of apical periodontitis in teeth with multiple root canals.

BACKGROUND: Problems attributed to the accumulation of wax (cerumen) are among the most common reasons for people to present to their general practitioners with ear trouble. Treatment for this condition often involves use of a wax softening agent (cerumenolytic) to disperse the cerumen, reduce the need for, or facilitate syringing, but there is no consensus on the effectiveness of the variety of cerumenolytics in use. OBJECTIVES: To assess the effectiveness of ear drops (cerumenolytics) for the removal of symptomatic ear wax. SEARCH METHODS: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2008 issue 2); MEDLINE; EMBASE; CINAHL; ISI Proceedings; Cambridge Scientific Abstracts; mRCT and additional sources for published and unpublished trials. The date of the most recent search was April 2008. SELECTION CRITERIA: We identified all randomised controlled trials in which a cerumenolytic was compared with no treatment, a placebo, or other cerumenolytics in participants with obstructing or impacted ear wax, and in which the proportion of participants with sufficient clearance of the external canal to make further mechanical clearance unnecessary (primary outcome measure) was stated or calculable. DATA COLLECTION AND ANALYSIS: The two authors reviewed all the retrieved trials and applied the inclusion criteria independently. MAIN RESULTS: Nine trials satisfied the inclusion criteria. In all, 679 participants received one of 11 different cerumenolytics. One trial compared active treatments with no treatment, three compared active treatments with water or a saline 'placebo', and all nine trials compared two or more active treatments. Eight trials included syringing as a secondary intervention.Overall, results were inconclusive. The majority of comparisons showed no difference between treatments. Meta-analysis of two high quality trials produced a statistical difference in favour of triethanolamine polypeptide over saline in preventing the need for syringing, but no other significant differences between treatments.In three trials of high to moderate quality, no difference was found between the effectiveness of either sodium bicarbonate ear drops, chlorbutanol, triethanolamine polypeptide oleate condensate or docusate sodium liquid versus a sterile water or saline 'placebo'.One trial of moderate methodological quality found all three treatments - sodium bicarbonate ear drops, chlorbutanol and sterile water - to be significantly better than no treatment at preventing the need for syringing.None of the higher quality trials demonstrated superiority of one agent over another in direct comparisons. AUTHORS' CONCLUSIONS: Trials have been heterogeneous and generally of low or moderate quality, making it difficult to offer any definitive recommendations on the effectiveness of cerumenolytics for the removal of symptomatic ear wax. Using drops of any sort appears to be better than no treatment, but it is uncertain if one type of drop is any better than another. Future trials should be of high methodological quality, have large sample sizes, and compare both oil-based and water-based solvents with placebo, no treatment or both.

Consumers are confronted with a large number of fragrance allergens from various sources. Until now, the discussion of exposure sources has mainly addressed cosmetic products and neglected other scented products in households. For the first time, fragrance allergens were evaluated in a complete set of detergents in households. In 131 households, we investigated the prevalence of detergents and searched their lists of ingredients for 26 fragrance allergens liable to be indicated on products according to the European Detergents Regulations. On the ingredient lists of 1447 products, these 26 fragrance substances were named almost 2000 times, most often limonene, linalool and hexyl cinnamal. Benzyl salicylate was used frequently in all-purpose cleaners. Linalool and limonene, hexyl cinnamal and butylphenyl methylpropional and citronellol and linalool co-occurred most often together in products. Fragrance allergens co-occurring together most frequently within households were eugenol, coumarin and cinnamyl alcohol. The study shows that detergents could play a relevant role for the exposure of consumers towards fragrance allergens and that they should not be underestimated as an exposure source during the exposure assessment.

Facial redness is a common difficult to control cosmetic problem representing various phases of rosacea. Using anti-inflammatory/antioxidant botanicals in moisturizer formulations is a possible approach to minimizing the erythema. This research utilized a common facial cleanser, but only applied the botanically based moisturizer to one half face to properly assess efficacy. 30 female subjects Fitzpatrick skin types I-IV 30-55 years of age with mild to moderate chronic facial redness, defined as a redness score of 3-6 on a 10-point scale, were enrolled. By the end of week 4, statistically significant improvement was seen on the cleanser/mask treated side in scaling (P less than 0.001), flaking (P less than 0.001), tactile smoothness (P less than 0.001), textural smoothness (P less than 0.001), firmness (P less than 0.001), radiance (P less than 0.001), luminosity (P less than 0.001), and overall appearance (P less than 0.001). Thus, cosmetic moisturizers may be useful in reducing facial redness. J Drugs Dermatol. 2018;17(6):671-676.

Chlorine dioxide complex™ is a new molecule to dermatology that is a unique, non-toxic, broad spectrum anti-microbial and keratolytic compound. Chlorine dioxide has been used as an antiseptic in industrial settings for decades, primarily in water treatment facilities for municipal water supplies and food preparation. The compound has exceptional antiseptic properties with no known potential for development of resistance. It is a true keratolytic and anti-inflammatory, but is non-toxic to human tissue due to its unique mechanism of action. Chlorine dioxide's use in consumer products was previously limited because it is inherently an unstable molecule that had to be used quickly after it was produced. However, the recent development of a complexed form of chlorine dioxide that retains its antimicrobial and keratolytic activity has allowed the development of products (AsepticMD, Aseptic Plus, Nashville, TN) that take advantage of the properties of this unique molecule. Here we report a case series demonstrating its efficacy as a cleanser in keratosis pilaris. J Drugs Dermatol. 2018;17(5):554-556.

OBJECTIVE: In order to achieve a faster and more reliable anterior rhinomanometric evaluation, nasal skin was prepared using benzoin tincture solution, which provides simpler and better adhesion of the foam tape to the nasal skin. METHOD: Two consecutive anterior rhinomanometry measurements were made, one with and one without benzoin tincture application. RESULTS: The average time taken to perform classic foam tape anterior rhinomanometry without benzoin tincture application was 281.32 seconds, and the average coefficients of variation for the right and left passages were 7.48 and 7.59 per cent, respectively. When benzoin tincture was used, the average time taken for completion of the tests was 121.24 seconds, and the average coefficients of variation for the right and left passages were 2.17 and 2.32 per cent. CONCLUSION: The use of benzoin tincture to clean the nasal skin before placing foam tape shortens the procedure duration and significantly increases test reliability.

OBJECTIVES: To evaluate the long-term effects of seven different cleaning methods on light transmittance, surface roughness, and flexural modulus of a polyurethane retainer material. MATERIALS AND METHODS: Polyurethane retainer specimens (Vivera®, Align Technology Inc) (70 specimens, n = 10 per method, 50.8 mm × 12.7 mm × 1.0 mm) were exposed to seven cleaning methods twice a week for 6 months. Before treatment and after 6 months, light transmittance, surface roughness, and flexural modulus of the specimens were quantified. Qualitative assessment of randomly selected specimens from each solution was performed at baseline and after 6 months using a scanning electron microscope. Statistical analyses were performed at the .05 significance level. RESULTS: Of the three test variables, light transmittance through the specimens was the only one that changed significantly from baseline to 6 months for all cleaning solutions, with all of them causing a decrease. However, except for 0.6% sodium hypochlorite showing a change in surface roughness values and 2.5% vinegar and toothbrushing showing an increase in flexural modulus, none of the other four cleaning methods resulted in significant changes in surface roughness or flexural modulus values for the polyurethane specimens between baseline and after 6 months. CONCLUSIONS: Of the seven cleaning methods, Invisalign® cleaning crystals, Polident®, and Listerine® showed the least amount of change in light transmittance values for the polyurethane specimens over 6 months, and they had no effect on surface roughness and flexural modulus values.

BACKGROUND: Outbreaks of infection associated with microbial biofilm in hospital hand washbasin U-bends are being reported increasingly. In a previous study, the efficacy of a prototype automated U-bend decontamination method was demonstrated for a single non-hospital pattern washbasin. It used two electrochemically activated solutions (ECA) generated from brine: catholyte with detergent properties and anolyte with disinfectant properties. AIM: To develop and test a large-scale automated ECA treatment system to decontaminate 10 hospital pattern washbasin U-bends simultaneously in a busy hospital clinic. METHODS: A programmable system was developed whereby the washbasin drain outlets, U-bends and proximal wastewater pipework automatically underwent 10-min treatments with catholyte followed by anolyte, three times weekly, over five months. Six untreated washbasins served as controls. Quantitative bacterial counts from U-bends were determined on Columbia blood agar, Reasoner's 2A agar and Pseudomonas aeruginosa selective agar following treatment and 24 h later. FINDINGS: The average bacterial densities in colony-forming units/swab from treated U-bends showed a >3 log reduction compared with controls, and reductions were highly significant (P<0.0001) on all media. There was no significant increase in average bacterial counts from treated U-bends 24 h later on all media (P>0.1). P. aeruginosa was the most prevalent organism recovered throughout the study. Internal examination of untreated U-bends using electron microscopy showed dense biofilm extending to the washbasin drain outlet junction, whereas treated U-bends were free from biofilm. CONCLUSION: Simultaneous automated treatment of multiple hospital washbasin U-bends with ECA consistently minimizes microbial contamination and thus the associated risk of infection.

OBJECTIVES: To evaluate the efficacy of ultrasound-guided local lauromacrogol injection combined with aspiration for treating cesarean scar pregnancy (CSP). METHODS: From July 2016 to December 2016, 18 patients diagnosed with CSP were treated with ultrasound-guided local lauromacrogol injection combined with aspiration. Clinical data and outcome were analysed. RESULTS: All patients were treated successfully. The amount of bleeding ranged between 10 and 50 mL. The duration of hospitalization ranged between 2 and 11 days. Serum ß-human chorionic gonadotropin (ß-hCG) decreased to the nondetectable level within 19-41 days. Menstruation recovery occurred after 10-24 days of normalization of serum ß-hCG level. Reproductive functions were preserved, and there were no untoward effects or complications. CONCLUSIONS: Ultrasound-guided local lauromacrogol injection combined with aspiration is an effective CSP therapy, as it was associated with a high success rate, short hospitalization and fast recovery. However, its wider application and popularization have to be validated on a larger patient population affected by CSP.

INTRODUCTION: The aim of the present study was to investigate the effect of Probiotics in Progress (PIP) on the establishment of a competitive flora as well as on antibiotic use and losses of suckling piglets in pig breeding farms. The tested products were PIP AHC® and PIP AHS® produced by "Chrisal AG" in Lommel, Belgium. PIP`s are cleaning products containing Bacillus spores. According to the manufacturer's specifications, they are able to establish a steady non-pathogenic stable flora. In a field trial in 19 pig breeding farms, the use of PIP-products did not lead to any reduction of antibiotic use or improvement of fertility parameters, especially in relation to losses of suckling piglets. In addition, we compared the bacterial flora using PIP products with the flora under conventional management conditions in a farrowing pen by means of swab samples. The use of PIP-products did not lead to any significant effect on the pen flora. Only very few swab samples contained a majority of probiotic Bacillus spp.
INTRODUCTION: Le but de la présente étude était d'étudier l'effet de Probiotica in Progress (PIP) sur l'établissement d'une flore concurrente ainsi que son effet sur la consommation d'antibiotiques et sur les pertes chez les porcelets dans les porcheries d'élevage. On a utilisé pour ce faire les produits PIP AHC® et PIP AHS® de la maison "Chrisal SA" à Lommel en Belgique. Les PIP sont des produits de nettoyage auxquels ont été adjoints des spores de Bacillus et qui, selon les informations du fabriquant, conduisent à l'établissement d'une flore d'écurie apathogène stable. Dans le cadre d'un essai de terrain dans 19 porcheries d'élevage, l'utilisation des produits PIP n'a amené aucune réduction de la consommation d'antibiotiques et aucune amélioration des performances, en particulier en ce qui concerne les pertes au niveau des porcelets. En outre on a comparé dans une porcherie, sur la base d'échantillons d'essuyage, la flore bactérienne présente sous l'effet de PIP à celle recueillie avec un management usuel. L'utilisation des produits PIP n'a pas amené d'effet significatif ou d'influence sur la flore bactérienne. Ce n'est que dans quelques échantillons qu'il a été possible de constater une présence augmentée de Bacillus spp. probiotiques.
