Assessment of diaper dermatitis using a novel electronic health record-embedded scale

OBJECTIVE

Quantify the evolution and severity of neonatal skin injury, specifically diaper skin compromise, by embedding a validated skin integrity evaluation into the electronic health record (EHR).

METHODS

Retrospective longitudinal cohort analysis of 747 patients stratified by gestation: 22-27, 28-31, 32-24, and 35-37 weeks, from birth to discharge. Primary outcomes were time to first perineal erythema, duration as percent days with erythema, and severity as maximum score. Data were analyzed using generalized linear models and multiple linear regression methods.

RESULTS

Seventy percent had erythema and, of these, 34% had at least one high score with bleeding. Days with erythema ranged from 34-44% (p < 0.05). Days to first erythema were inversely correlated with gestational age. Risks for severe injury included short time to first erythema, 5 or more stools/day, infection, and Caucasian race/ethnicity.

CONCLUSIONS

The EHR-based scale can be readily implemented to mitigate diaper skin compromise in premature infants.

Lactic acid sting test and capsaicin test differentially induce facial erythematous reaction in subjects with sensitive skin

BACKGROUND

Sensitivity skin (SS) is a common skin disorders, which have a various of clinical manifestation. Facial erythema is common objective symptom of SS. However, the reasons for the occurrence of erythema in sensitive skin are not fully understood.

AIMS

In this study, we preliminarily explain the possible factors inducing erythema of sensitive skin by evaluating facial erythematous reaction to lactic acid sting test (LAST) and capsaicin test (CAT) in subjects with sensitive skin.

METHODS

A total of 197 subjects were divided into five groups, that is, normal controls (NC), LAST-positive (LAST+ ), both LAST and CAT positive (L+ C+ ), both LAST and CAT negative (L- C- ) and CAT-positive (CAT+ ). Erythema index (EI), a* value, and tissue viability imaging (TIVI) were measured before and after LAST and CAT, The ΔEI, Δa*, and ΔTIVI before and after LAST and CAT were calculated, and the correlation between the scores of CAT, EI values, a* values, and TIVI values were analyzed to clarify the causes of facial erythema.

RESULTS

Our results showed that EI values and a* values were significantly higher in the L+ C+ and CAT+ group than in NC group, TIVI values were higher in the L+ C+ group than in NC group. ΔEI and Δa* values after LAST did not differ significantly among five groups. However, ΔEI values in L+ C+ group were higher than that in L- C- group, while Δa* values were higher in CAT+ group than in NC. Moreover, ΔTIVI values in L+ C+ group and CAT+ group were also significantly higher than that in NC group after capsaicin stimulation. CAT scores correlated positively with EI, a* and TIVI values.

CONCLUSION

Our results suggest that sensitive skin subjects with positive CAT are more likely to experience erythema reactions, and vasodilation is more pronounced after capsaicin stimulation. Reducing vascular and neural hyperreactivity could be therapeutic target in management of facial erythema in subjects with sensitive skin.

Treating rosacea with botulism toxin: Protocol for a systematic review and meta-analysis

BACKGROUND

Rosacea is a chronic inflammatory disease usually associated with persistent erythema and periodic flushing. This disease is difficult to treat, and the outcomes are often unsatisfactory and prone to recurrence. In recent years, botulinum toxin has been used as a new treatment for rosacea; however, its efficacy and safety remain under discussion. Although a systematic review of the effectiveness and safety of botulinum toxin has been previously conducted by other researchers, our systematic review and meta-analysis evaluate the efficacy of botulinum toxin from a more comprehensive and detailed perspective to provide evidence for clinicians.

METHODS

Any study using botulinum toxin for the treatment of rosacea was considered for the analysis.

RESULTS

A total of 22 studies were included, 9 of which were randomized controlled trials involving 720 subjects. After treatment, all studies showed varying degrees of improvement in patient signs and symptoms along with reduced Clinician's Erythema Assessment (CEA) scores. The improvement was maintained for several months, and the adverse effects were mild and self-limiting.

CONCLUSION

Botulinum toxin may be an effective treatment for patients with rosacea; however, further clinical evidence is needed to confirm its long-term efficacy and side effects. The study was preregistered with Prospero (CRD42022358911).

Fluctuations in Detection Indicators and Their Significance for the Diagnosis of Early Pressure Injury in Rat Models

PURPOSE

The aim of this study was to identify the most meaningful diagnostic indicator for distinguishing blanchable erythema (BE) and stage 1 pressure injury (early PI) in an in vivo (rat) model.

DESIGN

A prospective case-control design was used to complete a horizontal and vertical comparison of detection indicators during the process of fading of BE or the deterioration of early PI into ulcer in rat models.

MATERIALS AND SETTING

The sample comprised 5 hairless rats with 20 injuries, of which 10 were BE and the other 10 were early PI. Data were collected at Nagano College of Nursing in 2020 in Nagano, Japan.

METHODS

The BE and PI rat models were established by subjecting the dorsal skin of a hairless rat to compression between 2 neodymium magnets for 45 minutes and 3.45 hours, respectively. The affected skin was observed based on the following: (1) photography, (2) hardness, (3) temperature, (4) moisture, and (5) spectrophotometric (a* value and ultraviolet [UV] reflectance) measurements. All measurements of BE were performed at the beginning to 60 minutes after decompression, and those for early PI were performed until 48 hours after decompression.

RESULTS

Multiple BE factors, such as the degree of erythema (macroscopy and a* value), hardness, temperature, and moisture, were found to have unstable fluctuations. Only UV reflectance gradually decreased from 6 hours and decreased significantly at 48 hours after decompression (P = .001 vs 1 hour). In contrast to early PI, erythema in BE obviously faded within 10 minutes.

CONCLUSIONS

Study findings indicate that a continuous decrease in UV reflectance can reflect the worsening of hemorrhage in early (stage 1) PI. In contrast, other indicators including photography, skin hardness, temperature, and moisture fluctuated and did not prove predictive for PI progression. The obvious fading of erythema in BE a short time after decompression can be used for clinical observations.

Rosacea and seborrheic dermatitis differentially respond to lactic acid sting and capsaicin tests in Chinese women

BACKGROUND

Although rosacea and seborrheic dermatitis share some symptoms of sensitive skin, whether they respond differently to lactic acid sting and capsaicin tests, common tests for diagnosis of sensitive skin, is unknown.

OBJECTIVES

To reveal the cutaneous responses to lactic acid sting (LAST) and capsaicin test (CAT) in females with either rosacea vs. seborrheic dermatitis.

METHODS

A total of 60 patients with rosacea, 20 patients with seborrheic dermatitis and 40 normal controls were enrolled in the study. Their skin sensitivity to stimuli were evaluated following topical application of either 10% lactic acid solution or 0.001% capsaicin solution. Transepidermal water loss (TEWL) rates and erythema indexes were also measured on the face.

RESULTS

In comparison to normal controls, the positive rate to either LAST or CAT was significantly higher in subjects with rosacea (p < 0.001), but not in that with seborrheic dermatitis. Similarly, individuals with rosacea displayed a higher positive rate to both LAST and CAT than those with seborrheic dermatitis and normal controls (p < 0.001). In parallel, the LAST scores and CAT scores in individuals with rosacea were significantly higher than in that with either seborrheic dermatitis or normal controls (p < 0.001). The baseline TEWL rates and erythema indexes were higher in individual with rosacea than in normal controls (p < 0.001). But the baseline TEWL rates and erythema indexes did not differ significantly between subjects with rosacea and that with seborrheic dermatitis. Moreover, LAST scores and CAT scores correlated positively with TEWL (p < 0.0001). TEWL rates were higher in CAT positive than in CAT negative subjects (p < 0.0001). Finally, erythema index correlated positively with CAT scores (p < 0.0001), but not with LAST scores (p = 0.0842).

CONCLUSIONS

Skin responses to LAST and CAT differ between individuals with rosacea and those with seborrheic dermatitis, possibly due to the differences in epidermal permeability barrier and the neurovascular hyperreactivity. The higher LAST and CAT scores, as well as positive rates of both LAST and CAT can be attributable to inferior permeability barrier and the neurovascular hyperreactivity in subjects with rosacea.

Equipment developed for simplifying routine phototesting in dermatology

Some people react abnormally when exposed to sunlight by getting easily burned or develop a rash. When testing a patient's level of photosensitivity in the clinic, the UVR dose to provoke erythema is determined by the minimal erythema dose (MED) test. Subsequently, a photoprovocation test is performed to detect abnormal skin reactions by daily exposing the skin to UVR for several consecutive days. Associated problems in MED testing include choice of an even skin area for testing, patients keeping still during the test, testing with different UVR doses simultaneously, and securing clear borders of erythema. To address these issues, a MED Test Patch was developed which adheres closely to the skin to ensure sharp erythema borders and provides six irradiation fields with decremental doses of 20%. For MED testing, we constructed a solar simulator and LED lamps with peak emissions at 309 and 370 nm, small enough to be mounted directly on to the MED Test Patch and accommodate patient movements. These lamps and a 415 nm LED can also be used for provocation testing which is best performed on the back where the skin is assumed to have identical UVR sensitivity, and the area is large enough for adjacent MED and provocation test fields. Reading of erythema is still performed by visual and tactile evaluation. The UVA and UVB MED test can be performed in 1 h. The advantage of these developments is an easy-to-use, standardized test method with improved accuracy of the results.

Narrow-Band Intense Pulsed Light as Treatment for Erythematotelangiectatic Rosacea: A Retrospective Study

BACKGROUND

Erythematotelangiectatic rosacea can be successfully treated using various laser and light-based devices. However, the use of narrow-band intense pulsed light for the treatment of erythematotelangiectatic rosacea has not been investigated in detail. This retrospective study aimed to analyze the clinical efficacy of narrow-band intense pulsed light (500-600 nm) for the treatment of erythematotelangiectatic rosacea among Chinese individuals.  Methods: Patients with erythematotelangiectatic rosacea who had completed 3 sessions of treatment with narrow-band intense pulsed light and follow-up from July 2016 to December 2018 were retrospectively evaluated. Clinical improvement was assessed by 2 blinded dermatologists based on photographs obtained at each follow-up visit using the clinician erythema assessment scale and 5-grade scale.

RESULTS

Forty-five patients with erythematotelangiectatic rosacea treated with narrow-band intense pulsed light were included in this study. The effectiveness and excellent rates after 3 treatment sessions were 68.9% and 35.6%, respectively. An average of 2 treatment sessions was required among patients who achieved good or excellent clearance of erythema and telangiectasia. Except for transient erythema and edema, no severe adverse effects were observed.

CONCLUSIONS

Narrow-band intense pulsed light is a safe and effective treatment for erythematotelangiectatic rosacea. Even with a small number of treatment sessions, narrow-band intense pulsed light can deliver a significant therapeutic effect, which may be applicable in clinical practice.

Dermatoscopic Features of Early Erythema Chronicum Migrans

Dear Editors, A 37-year-old man from a Lyme disease-endemic area presented with a one-week old rapidly expanding rash on his right calf. He lacked other comorbidities or symptoms such as fever, weakness, lack of appetite, or joint pain, but recalled removing a tick from the same region three weeks earlier. Inspection revealed a round, bluish-red erythematous patch with a central clearing (Figure 1). The patient experienced no discomfort, but the rash was warm and faded easily when palpated. Dermatoscopic inspection revealed collarette-shaped white scales encircling the punctum of the tick bite in the center (Figure 2, left inset). There were three distinct background zones towards the periphery: skin-colored, bluish-red, and bright red. The transitions between the zones were not fully discernable. Red purpuric dots and clods were randomly distributed over these backgrounds, gradually increasing towards the periphery (Figure 2). The rash was diagnosed as erythema chronicum migrans (ECM), and the patient was started on doxycycline 100 mg BID. The expansion of the rash was stopped, while the speed of central clearing was increased. Half of the rash had healed by the third day (Figure 1, left inset), and it had completely disappeared by the seventh (Figure 1, right inset). Anti-Borrelia burgdorferi antibodies were initially negative for IgM and positive for IgG, but both tested positive two weeks later. ECM is the hallmark of early-stage lyme disease, but it is not always present. In addition to the classically described bull's eye appearance, ECM may appear as homogenous erythematous patches, interrupted annular patches, or patches with hemorrhagic or purpuric components (1). It can manifest anywhere except in the palmoplantar region, but it is more common around large joints. Despite the morphological variations of ECM, the clinical presentation is often clear and distinct enough for dermatologists to correctly diagnose more than 90% of patients (1). Diagnostic procedures such as ELISA or Western blot are employed in cases when the ECM is absent or atypical. However, their reliability is low due to the lack of standardization, limited coverage of Borrelia spp., and significant false-positive and false-negative rates (1). Seropositivity owing to previous asymptomatic infection in individuals residing in endemic areas may result in incidental positive findings. Alternative methods, including isolating the pathogen or PCR testing from biopsy samples have similar drawbacks (1). Histopathological investigations are another practical method that yields supportive findings. ECM exhibits diffuse perivascular and interstitial inflammation, including lymphocytes, eosinophils, and plasma cells (2), which corresponds to background erythema in dermatoscopy. As the inflammation develops, the newly-developed regions are superficial and brilliant red, but the surface inflammation fades over time, leaving bluish erythema, which correlates to deeper inflammation (2,3) dermoscopy is gaining appreciation in assisting the diagnosis of nonneoplastic diseases, especially inflammatory dermatoses (inflammoscopy). Extravasated erythrocytes combined with perivascular inflammation (2) generate purpuric pinkish-red dots and clods. Given the greater efficacy of early treatment and the ambiguity surrounding diagnostic methods, clinical findings should be deemed adequate to commence therapy, particularly in endemic regions (1). Dermatoscopic examination of ECM offers a quick and low-cost alternative approach for supporting the diagnosis. However, as emphasized by Errichetti, dermatoscopic examination in non-neoplastic diseases should be regarded as the second step of a "2-step procedure", with differential diagnoses established first by history and clinical examination (3). A systematic investigation of early and late, typical and atypical lesions would improve the reliability and utility of this method.

Pediatric erythema ab igne: clinical aspects and diagnostic issues

Erythema ab igne is a dermatological condition resulting from repeated low-grade heat exposure (below the burning point), which can variably manifest with reticulated erythema and skin hyperpigmentation. Not infrequently, the cause of such a skin disorder is not immediately evident or reported by patients, especially if these are children. Compared to adults, erythema ab igne is rare in children and, if the general practitioners and pediatricians are not aware of this disorder, pediatric patients are often addressed to rheumatologists and/or undergo useless immunological investigations. Here, we performed a systematic case-based review, which finally included 32 cases of pediatric erythema ab igne (in addition to our new clinical report), and discussed the main clinical aspects and issues of this clinical entity in children. In detail, similarities of erythema ab igne with livedo reticularis and/or vasculitis-related rashes sometimes can lead to perform a panel of immunological investigations, which could be avoided. Indeed, our analysis emphasizes the importance of a careful and complete patient's anamnesis, including active questioning about the potential exposure to any physical agents (including heat sources) that may cause dermatological lesions. We also highlight some peculiarities in terms of location and heat injury in children developing erythema ab igne, based on the presence or absence of comorbidities.

CONCLUSION

The occurrence of erythema ab igne in children (and especially in adolescents) is likely to increase in the next years because of the greater and sometimes inappropriate use of technological devices. Physicians should be aware of this condition in order to prevent patients from useless investigations, especially in the differential diagnosis of rheumatic disorders. A careful and complete patient's history with active questioning about the potential exposure to heating source is often decisive to diagnose erythema ab igne.

WHAT IS KNOWN

• Erythema ab igne is a dermatological condition which is mainly described in adults exposed to heating source at the workplace.

WHAT IS NEW

• The occurrence of erythema ab igne in children is likely to increase in the next years because of the greater and sometimes inappropriate use of technological devices. • Erythema ab igne in children can be classified in two main categories, based on the presence or absence of comorbidity. • A careful and complete anamnesis (including the active questioning about potential exposure to any heating source) is the mainstay for diagnosing erythema ab igne in children.

Using Technology to Detect Erythema Across Skin Tones

OBJECTIVE

To examine the effectiveness of the ColorMeter DSM III (ColorMeter; Cortex Technology) at grouping individuals by skin tone and measuring erythema/skin discoloration after erythema induction across skin tones.

METHODS

This pre/post experimental study induced erythema on a convenience sample of 61 healthy adults. Skin tone at baseline was measured using the ColorMeter, Munsell Soil Color Chart 5YR (Munsell), and Pantone SkinTone Guide (Pantone) and compared with the Eumelanin Human Skin Colour Scale (Eumelanin Scale) groupings. Erythema and melanin values on the arm immediately and after recovery time were compared with baseline values. Melanin was measured at five body regions on the face and arm.

RESULTS

Participants were predominantly women (64% [n = 39] women, 36% [n = 22] men) and young (mean, 28.8 ± 14.3 years); 5% (n = 3) were Hispanic, 26% (n = 16) Asian, 29% (n = 18) Black, 38% (n = 23) White, and 7% (n = 4) identified with more than one race. ColorMeter lightness (L*) and melanin measures were strongly correlated with both Munsell and Pantone values. Munsell skin tone groups were not aligned with Eumelanin Scale groupings. Most participants were in the Eumelanin intermediate-low group, and this changed depending on which body location melanin value was used. The change in erythema from baseline did not differ significantly across skin tone groups at the ulnar head, but on the forearm at the delayed time point, significant differences existed between light and both medium and dark skin tone groups (P = .001; 95% CI, 0.04-0.37).

CONCLUSIONS

The ColorMeter provides an effective objective measure of skin tone and erythema/discoloration across various skin tones and may improve on current standards for detection. The proposed Eumelanin Scale-Modified provides additional sensitivity for persons with medium skin tones.

Long-Term Safety and Efficacy of Twice-Daily Topical Clascoterone Cream 1% in Patients Greater Than or Equal to 12 Years of Age With Acne Vulgaris

BACKGROUND

Clascoterone cream 1% is approved for the treatment of acne vulgaris in patients aged ≥ 12 years based on results from two 12-week Phase 3 studies in patients with moderate-to-severe acne. Safety and efficacy of clascoterone in patients aged ≥ 12 years from an open-label, long-term extension study are presented.  Methods: Enrolled patients applied clascoterone cream 1% twice daily to the entire face and, if desired by the patient and/or investigator, truncal acne, for up to 9 months. Patients achieving Investigator’s Global Assessment score of 0 or 1 (IGA 0/1) could stop treatment and resume if/when acne worsened. Safety was assessed from treatment-emergent adverse events (TEAEs) and local skin reactions (LSRs [telangiectasia, skin atrophy, striae rubrae, erythema, edema, scaling/dryness, stinging/burning, and pruritus]) in all treated patients. Efficacy was assessed from IGA at each visit among those completing the study per-protocol (PP); face and trunk were evaluated individually.  Results: Of 600 patients aged ≥ 12 years (original randomization: 311 clascoterone, 289 vehicle), 343 completed the extension study (177 clascoterone, 166 vehicle). There were 187 TEAEs in 108/598 clascoterone-treated patients (18.1%), including 56/311 (18.0%) and 52/287 (18.1%) patients originally randomized to clascoterone and vehicle, respectively; the most common LSRs (previous clascoterone/vehicle) were erythema (face, 8.0%/7.7%) and scaling/dryness (face, 10.0%/7.3%). The percentage of PP patients with facial and truncal IGA 0/1 increased to 48.9% (156/319) and 52.4% (65/124), respectively, at study end.

CONCLUSIONS

Clascoterone cream 1% maintained a favorable safety and efficacy profile for up to 12 months in patients aged ≥ 12 years. Eichenfield LF, Hebert AA, Stein Gold L, et al. Long-term safety and efficacy of twice-daily topical clascoterone cream 1% in patients ≥ 12 years of age with acne vulgaris. J Drugs Dermatol. 2023;22(8):810-816. doi:10.36849/JDD.7592.

Targetoid-like lesions and chilblain-like erythema manifested on hands and feet: A case of Rowell syndrome from China

BACKGROUND

Rowell syndrome (RS) is an uncommon condition characterized by erythema multiforme (EM)-like lesions and lupus erythematosus. It is more common in females, and EM may be the first manifestation of the disease with positive autoantibodies, such as antinuclear antibody (ANA), SSA, SSB and rheumatoid factor. The pathogenesis of RS is unknown and is likely caused by drug induction, ultraviolet exposure and infection.

METHOD

We describe a case of RS from China which presented as characteristic targetoid-like lesions and chilblain-like erythema on hands and feet. This is a case of RS in a female patient from the inpatient department of dermatology.

RESULTS

A 41-year-old female with systemic lupus erythematosus exhibited chilblain-like erythema and characteristic EM lesions on her extremities. She tested positive for serum ANA (1:320) and anti-double-stranded DNA, as well as other autoantibodies. Systemic glucocorticoids and hydroxychloroquine worked effectively for her.

CONCLUSION

The present case met diagnostic criteria of RS. Notably, there was a co-occurrence of facial butterfly erythema, chilblain-like erythema and EM lesions distributed on the limbs in this case.

Successful Management of Erythema Dyschromicum Perstans Following Topical Ruxolitinib Therapy

Erythema dyschromicum perstans (EDP) is a rare cutaneous disorder in which patients develop gray or blue-brown macules or patches on their bodies.1 This condition does not appear to have a gender or age predilection. The diagnosis of EDP is essentially clinical, with histopathology findings being nonspecific. To date, treatment for EDP varies. The use of several therapies, including dapsone, clofazimine, retinoid A, tacrolimus, and ultraviolet light have been reported but with minimal effectiveness.5 We report a case of EDP occurring in a patient following the COVID-19 vaccine that was given topical ruxolitinib with success in treatment. To our knowledge, this is the first report of the use of topical ruxolitinib in treatment of EDP with successful management. J Drugs Dermatol. 2022;22(3): doi:10.36849/JDD.7156.

Comparison of 1064 nm Q-switched Nd:YAG laser and Jessner peeling in melasma treatment

Melasma is an acquired hyperpigmentation disease characterized by hyperpigmented patches in sun-exposed areas that significantly impairs life quality. Topical treatments such as hydroquinone, retinoic acid, azelaic acid, chemical peels and laser treatments are among the main treatment options. In our study, we aimed to compare the effectiveness of Jessner peeling and 1064 nm Q-switched Nd:YAG laser in melasma treatment. For this purpose, Jessner peeling was applied to 20 patients and 1064 nm Q-switched Nd: YAG laser was applied to 19 patients of 39 melasma patients who applied to the cosmetology unit of Ege University department of dermatology and venereal diseases between November 2018-March 2020. Thirty seven patients completed the study. Changes in MASI, pigment and erythema scores measured by mexameter before and after treatment were compared for two groups. A statistically significant decrease in MASI scores, pigment and erythema scores was observed in both groups with no significant difference between two groups. In conclusion, in our study, it has been shown that Jessner peeling and 1064 nm Q-switched Nd:YAG laser are equally effective in treatment of melasma.

[Red man syndrome as a complication of vancomycin therapy]

Red man syndrome (RMS) is a side effect of vancomycin therapy and manifests itself mainly by a red blotchy rash with itching and sometimes muscle pain and a decrease of arterial blood pressure.

A CASE REPORT

24-year-old patient admitted to hospital with a history of chest pain radiating to the back. EKG has shown the depression of PQ, in the ECHO mark of liquid in the pericardial cavity and the increase of CRP and troponin concentrations. The patient was diagnosed with acute pericarditis and treated with ibuprofen and colchicine. Due to the increasing parameters of inflammation, a bacterial etiology was suspected and vancomycin was administered. During antibiotic therapy, there were symptoms of a mild adverse reaction in the form of a maculopapular rash and periodic decreases in blood pressure. RMS was diagnosed and symptoms resolved after treatment with cetirizine.

CONCLUSIONS

RMS should be distinguished from anaphylaxis and treated according to the diagnosis.
