Abstract
We report a technique for the noninvasive detection of skin cancer by imprint desorption electrospray ionization mass spectrometry imaging (DESI-MSI) using a transfer agent that is pressed against the tissue of interest. By noninvasively pressing a tape strip against human skin, metabolites, fatty acids, and lipids on the skin surface are transferred to the tape with little spatial distortion. Running DESI-MSI on the tape strip provides chemical images of the molecules on the skin surface, which are valuable for distinguishing cancer from healthy skin. Chemical components of the tissue imprint on the tape strip and the original basal cell carcinoma (BCC) section from the mass spectra show high consistency. By comparing MS images (about 150-μm resolution) of same molecules from the tape strip and from the BCC section, we confirm that chemical patterns are successfully transferred to the tape stripe. We also used the technique to distinguish cherry angiomas from normal human skin by comparing the molecular patterns from a tape strip. These results demonstrate the potential of the imprint DESI-MSI technique for the noninvasive detection of skin cancers as well as other skin diseases before and during clinical surgery.

Dupilumab significantly improves sleep in adults with atopic dermatitis: results from the 12-week placebo-controlled period of the 24-week phase IV randomized double-blinded placebo-controlled DUPISTAD study. Br J Dermatol 2023; 189:685-694. [PMID: 37562034 DOI: 10.1093/bjd/ljad284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 08/03/2023] [Accepted: 08/05/2023] [Indexed: 08/12/2023]
Abstract
BACKGROUND Sleep disturbance is a prominent symptom of atopic dermatitis (AD) and can result in insomnia, daytime fatigue, drowsiness, reduced productivity and impaired quality of life (QoL). OBJECTIVES The Dupilumab Effect on Sleep in AD Patients (DUPISTAD) phase IV randomized double-blinded placebo-controlled study evaluated the impact of dupilumab treatment on sleep and other patient- and physician-reported outcomes. METHODS Adults with moderate-to-severe AD were randomized 2 : 1 to dupilumab 300 mg once every 2 weeks (q2w) or placebo for 12 weeks; concomitant topical corticosteroids were permitted. Patients subsequently entered an open-label phase and received dupilumab 300 mg q2w for a further 12 weeks. The primary endpoint was the percentage change in sleep quality from baseline to week 12, assessed using a novel numeric rating scale (NRS). Secondary and exploratory endpoints included percentage change in peak pruritus NRS (PP NRS), change in SCORing Atopic Dermatitis (SCORAD), SCORAD sleep visual analogue scale (VAS), Eczema Area and Severity Index, Patient-Reported Outcomes Measurement Information System (PROMIS) sleep-related impairment T-score and the Epworth Sleepiness Scale. Sleep diary and wrist actigraphy measurements were recorded throughout the study. RESULTS In total, 127 patients received dupilumab and 61 patients received placebo. Demographic and baseline disease characteristics were balanced between groups. Sleep quality NRS significantly improved in patients treated with dupilumab by week 12 vs. placebo [least squares mean of the difference (LSMD) -15.5%, P < 0.001]. PP NRS (LSMD -27.9%, P < 0.001), SCORAD (LSMD -15.1, P < 0.001), SCORAD sleep VAS (LSMD -2.1, P < 0.001) and PROMIS T-score (LSMD -3.6, P < 0.001) were also significantly improved at week 12 with dupilumab vs. placebo. The overall percentage of patients reporting treatment-emergent adverse events was lower in the dupilumab group (56.7%) than in the placebo group (67.2%). CONCLUSIONS Dupilumab significantly improved sleep quality and perception of sleep continuity, itch, metrics of AD severity and QoL in adults with moderate-to-severe AD, with an acceptable safety profile compared with placebo.

Abstract
We developed a digital tool for home-based monitoring of skin disease, our digital tool. In the current observational pilot study, we found that DORA is feasible to use in practice, as it has a high patient compliance, retention and satisfaction. Clinicans rated the photos generally good quality or perfect quality. These results show that the digital health tool DORA can easily be used by patients to send photos to their dermatologist, which could reduce unnecessary clinical visits. It may also be used in other settings where digital literacy barriers and unequal access to dermatologists contribute to healthcare disparities.

Development and Clinical Evaluation of an Artificial Intelligence Support Tool for Improving Telemedicine Photo Quality. JAMA Dermatol 2023; 159:496-503. [PMID: 36920380 PMCID: PMC10018405 DOI: 10.1001/jamadermatol.2023.0091] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Accepted: 01/12/2023] [Indexed: 03/16/2023]
Abstract
Importance Telemedicine use accelerated during the COVID-19 pandemic, and skin conditions were a common use case. However, many images submitted may be of insufficient quality for making a clinical determination. Objective To determine whether an artificial intelligence (AI) decision support tool, a machine learning algorithm, could improve the quality of images submitted for telemedicine by providing real-time feedback and explanations to patients. Design, Setting, and Participants This quality improvement study with an AI performance component and single-arm clinical pilot study component was conducted from March 2020 to October 2021. After training, the AI decision support tool was tested on 357 retrospectively collected telemedicine images from Stanford telemedicine from March 2020 to June 2021. Subsequently, a single-arm clinical pilot study was conducted to assess feasibility with 98 patients in the Stanford Department of Dermatology across 2 clinical sites from July 2021 to October 2021. For the clinical pilot study, inclusion criteria for patients included being adults (aged ≥18 years), presenting to clinic for a skin condition, and being able to photograph their own skin with a smartphone. Interventions During the clinical pilot study, patients were given a handheld smartphone device with a machine learning algorithm interface loaded and were asked to take images of any lesions of concern. Patients were able to review and retake photos prior to submitting, so each submitted photo met the patient's assumed standard of clinical acceptability. A machine learning algorithm then gave the patient feedback on whether the image was acceptable. If the image was rejected, the patient was provided a reason by the AI decision support tool and allowed to retake the photos. Main Outcomes and Measures The main outcome of the retrospective image analysis was the receiver operator curve area under the curve (ROC-AUC). The main outcome of the clinical pilot study was the image quality difference between the baseline images and the images approved by AI decision support. Results Of the 98 patients included, the mean (SD) age was 49.8 (17.6) years, and 50 (51%) of the patients were male. On retrospective telemedicine images, the machine learning algorithm effectively identified poor-quality images (ROC-AUC of 0.78) and the reason for poor quality (blurry ROC-AUC of 0.84; lighting issues ROC-AUC of 0.70). The performance was consistent across age and sex. In the clinical pilot study, patient use of the machine learning algorithm was associated with improved image quality. An AI algorithm was associated with reduction in the number of patients with a poor-quality image by 68.0%. Conclusions and Relevance In this quality improvement study, patients use of the AI decision support with a machine learning algorithm was associated with improved quality of skin disease photographs submitted for telemedicine use.

Abstract
Abstract
Sleep disturbance is considered one of the most prevalent symptoms of atopic dermatitis (AD), and is associated with daytime sleepiness, anxiety and depression. In previous phase 3 trials, dupilumab treatment demonstrated significant improvement in objective AD signs and severity of symptoms, including sleep disturbance and mental health symptoms. To investigate the effect of dupilumab for up to 24 weeks on sleep quality, daytime sleepiness, anxiety and depression, using data from the DUPISTAD (NCT04033367) study. The randomized, phase 4 DUPISTAD study, was divided into two 12-week periods: an initial double-blind placebo-controlled period, and a subsequent 12-week open-label extension (OLE) period. The 24-week study enrolled adult patients with moderate-to-severe AD (Eczema Area and Severity Index score ≥12, Peak Pruritus Numeric Rating Scale [NRS] score ≥3, Sleep Disturbance NRS average score ≥5) who showed an inadequate response to topical treatments. These patients were randomized 2 : 1 to dupilumab 300 mg every 2 weeks (q2w) for both the double-blind and OLE periods or placebo for the initial double-blind period, followed by dupilumab 300 mg q2w for the OLE period. The use of concomitant topical corticosteroids was permitted as needed by both groups throughout the study. Endpoints included mean change from baseline to week 24 for Patient-Reported Outcome Measures Information System (PROMIS) Sleep T-score (standardized score ranging from 30 [best] to 80 [worst], with a mean of 50), Epworth Sleepiness Scale (ESS; scored 0–24; higher values indicate increased daytime sleepiness), and Hospital Anxiety and Depression Scale (HADS; scored 0–21; higher values indicate a worse outcome). Throughout the study, patients also completed a Sleep Diary, recording the NRS of restfulness upon waking up (scored 0–10; lower values indicate a worse outcome). Statistical comparisons were not performed on the data collected during the OLE observation period. A total of 188 patients were enrolled in the study: 127 received continuous dupilumab (dupilumab–dupilumab group) and 61 received placebo to week 12 and then dupilumab to week 24 (placebo–dupilumab group). Baseline demographics and disease characteristics were well balanced. Improvement from baseline in sleep quality, daytime sleepiness, anxiety and depression was observed at week 24 in both groups, as illustrated by the mean change from baseline in PROMIS Sleep T-scores (−12.5 in the dupilumab–dupilumab group and −11.7 in the placebo–dupilumab group), ESS scores (−4.6 in the dupilumab–dupilumab group and −3.7 in the placebo–dupilumab group), HADS anxiety scores (−3.8 in the dupilumab–dupilumab group and −4.4 in the placebo–dupilumab group), HADS depression scores (−4.4 in the dupilumab–dupilumab group and −3.4 in the placebo–dupilumab group), and the NRS of restfulness upon a waking-up item of the Sleep Diary (+3.3 in the dupilumab–dupilumab group and +3.4 in the placebo–dupilumab group). The improvement achieved by the placebo–dupilumab group converged with that of the dupilumab–dupilumab group during the OLE period, as shown by the mean change from week 12 to week 24 in PROMIS Sleep T-score (−3.8), ESS score (−1.9), HADS anxiety score (−1.6), HADS depression score (−0.9) and NRS of restfulness upon a waking-up item of the Sleep Diary (+1.5). The safety profile of dupilumab was consistent with the known safety profile. Dupilumab provided sustained improvement through 24 weeks in patient-reported measures of sleep, daytime sleepiness, anxiety, and depression in adult patients with moderate-to-severe AD. Patients who were switched from placebo to dupilumab at week 12 showed rapid improvement in these parameters after the switch, eventually matching the improvement achieved by patients who received dupilumab from baseline through week 24.

Abstract
Abstract
Atopic dermatitis (AD) is a chronic disease characterized by sleep disturbance, associated with night-time itching and scratching, along with skin pain, resulting in daytime drowsiness, diminished daytime productivity and overall reduced quality of life (QoL) in patients with AD. To report the effect of up to 24 weeks of dupilumab treatment on the QoL of adult patients with moderate-to-severe AD, using data from the DUPISTAD (NCT04033367) study. Phase 4, a randomized DUPISTAD study, comprised two 12-week periods: an initial placebo-controlled double-blind period, and a subsequent 12-week open-label extension (OLE) period. Adult patients with moderate-to-severe AD (Eczema Area and Severity Index score ≥12, Peak Pruritus Numeric Rating Scale [NRS] score ≥3, Sleep Disturbance NRS average score ≥5), showing an inadequate response to topical treatments, were randomized 2 : 1 to dupilumab 300 mg every 2 weeks (q2w) for both the double-blind and OLE periods or placebo for the initial double-blind period, followed by dupilumab 300 mg q2w for the OLE period. The use of concomitant topical corticosteroids was permitted during the entire course of the study. Endpoints, including Patient-Oriented Eczema Measure (POEM; scored 0–28, with higher values indicating a worse outcome), Dermatology Life Quality Index (DLQI; scored 0–30, with higher values indicating a poorer QoL), Skin Pain and Sensitivity NRS (scored 0–10, where 0 = no pain/normal sensitivity and 10 = worst possible pain/extremely sensitive) were assessed from baseline to week 24. The enrolled patients also completed a Work Productivity and Activity Impairment Questionnaire (WPAI-AD), including an NRS rating of the AD-Affected Ability to do Regular Daily Activities other than a Job (scored 0–10, where 0=‘no effect’ and 10=‘prevented me from doing my daily activities’). Formal statistical comparisons were not performed on the data resulting from the OLE period. The DUPISTAD study enrolled a total of 188 patients: 127 patients received dupilumab throughout (dupilumab–dupilumab group), and 61 patients received a placebo and then switched to dupilumab (placebo–dupilumab group). Baseline demographics and disease characteristics were well balanced. Improvement from baseline in AD-related patient-reported QoL indicators and AD symptoms was observed at week 24 in both groups, as illustrated by the mean change from baseline in POEM total scores (−14.6 in the dupilumab–dupilumab group and −15.9 in the placebo–dupilumab group), DLQI scores (−12.6 in the dupilumab–dupilumab group and −13.4 in the placebo–dupilumab group), Skin Pain NRS scores (−4.7 in the dupilumab–dupilumab group and −5.0 in the placebo–dupilumab group), Skin Sensitivity NRS scores (−4.6 in the dupilumab–dupilumab group and −5.0 in the placebo–dupilumab group), and the WPAI-AD NRS of Ability to do Regular Daily Activities scores (−4.2 in the dupilumab–dupilumab group and −3.8 in the placebo–dupilumab group). The placebo–dupilumab group experienced most of this improvement during the OLE period, as illustrated by the mean change from week 12 to week 24 in POEM total score (−11.5), DLQI score (−5.5), Skin Pain NRS score (−3.0), Skin Sensitivity NRS score (−3.0) and the WPAI-AD NRS of Ability to do Regular Daily Activities score (−2.0). The safety profile of dupilumab was consistent with the known safety profile. Dupilumab provided sustained improvements through 24 weeks in AD-related patient-reported measures of QoL and AD symptoms in adults with moderate-to-severe AD. Patients who were switched from placebo to dupilumab at week 12 showed rapid improvement in these parameters after the switch, eventually matching the improvement achieved by patients who received dupilumab from baseline through week 24.

Abstract
Background Recessive dystrophic epidermolysis bullosa (RDEB) is a rare, devastating blistering genodermatosis caused by mutations in the COL7A1 gene, which encodes for type VII collagen and is necessary for dermal-epidermal adhesion and integrity. Disease manifestations include severe and debilitating wounds, aggressive squamous cell carcinomas, and premature death; however, there are currently no approved therapies. This Phase 1/2a, open-label study evaluated the long-term efficacy and safety of gene-corrected autologous keratinocyte grafts (EB-101) for chronic RDEB wounds.
Methods Autologous keratinocytes were harvested from participants with severe RDEB, transduced with a retrovirus containing the full-length COL7A1 gene, and grown into 5 × 7 cm (35 cm2) sheets. Gene-corrected keratinocyte sheets were then transplanted onto chronic RDEB wounds present for ≥ 12 weeks.
Results Seven adult participants with severe RDEB were grafted with six sheets each (42 total sheets) onto wounds and followed for a mean of 5.9 years (range 4–8 years). Long-term improvements in wound healing and symptoms were observed. At year five, 70% (21/30) of treated sites demonstrated ≥ 50% wound healing compared to baseline by investigator global assessment. No sites with ≥ 50% wound healing were painful or pruritic, compared to 67% (6/9) of sites with < 50% wound healing (p < 0.001) at year five. Grafts were well-tolerated throughout long-term follow-up. No serious adverse events related to treatment were reported over a mean of 5.9 years of follow-up. No persistent systemic autoimmunity against type VII collagen or replication-competent retrovirus infections were identified, and no participants developed squamous cell carcinomas related to treatment during long-term follow-up. Conclusions Treatment with EB-101 appears safe and efficacious, and produces long-term improvements in wound healing, pain, and itch for RDEB patients. Results from the Phase 3 randomized controlled trial are forthcoming. Trial registration ClinicalTrials.gov, NCT01263379. Registered December 15, 2010. https://clinicaltrials.gov/ct2/show/NCT01263379 Supplementary Information The online version contains supplementary material available at 10.1186/s13023-022-02546-9.

Abstract
An estimated 3 billion people lack access to dermatological care globally. Artificial intelligence (AI) may aid in triaging skin diseases and identifying malignancies. However, most AI models have not been assessed on images of diverse skin tones or uncommon diseases. Thus, we created the Diverse Dermatology Images (DDI) dataset-the first publicly available, expertly curated, and pathologically confirmed image dataset with diverse skin tones. We show that state-of-the-art dermatology AI models exhibit substantial limitations on the DDI dataset, particularly on dark skin tones and uncommon diseases. We find that dermatologists, who often label AI datasets, also perform worse on images of dark skin tones and uncommon diseases. Fine-tuning AI models on the DDI images closes the performance gap between light and dark skin tones. These findings identify important weaknesses and biases in dermatology AI that should be addressed for reliable application to diverse patients and diseases.

A global, cross-sectional survey of patient-reported outcomes, disease burden, and quality of life in epidermolysis bullosa simplex. Orphanet J Rare Dis 2022; 17:270. [PMID: 35841105 PMCID: PMC9287948 DOI: 10.1186/s13023-022-02433-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 06/30/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Epidermolysis bullosa simplex (EBS) comprises a group of rare, blistering genodermatoses. Prior work has been limited by small sample sizes, and much remains unexplored about the disease burden and health-related quality of life (QOL) of patients with EBS. The aim of this study was to characterize the most common patient-reported clinical manifestations and the health-related impact of QOL in EBS, and to examine differences in disease burden by age. METHODS Patients with a diagnosis of epidermolysis bullosa (EB) or their caregivers completed a one-time online survey administered by EBCare, an international online EB registry. Survey data from respondents self-reporting a diagnosis of EBS were analyzed for clinical and wound manifestations, medication use, and QOL (using Quality of Life in Epidermolysis Bullosa [QOLEB] scores). Differences across age groups were assessed using Kruskal-Wallis and Fisher's exact tests. RESULTS There were 214 survey respondents with EBS. The mean age was 32.8 years (standard deviation = 19.2). Many respondents reported blisters (93%), recurrent wounds (89%), pain (74%), chronic wounds (59%), itch (55%), and difficulty walking (44%). Mean QOLEB score was 14.7 (standard deviation = 7.5) indicating a "moderate" impact on QOL, and 12% of respondents required regular use of opiates. Findings were consistent in subgroup analyses restricted to respondents with diagnostic confirmation via genetic testing or skin biopsy (n = 63 of 214). Age-stratified analyses revealed differences in disease burden: younger respondents were more likely to self-report severe disease (24% vs. 19% vs. 5% for respondents aged 0-9 vs. 10-17 vs. 18 + , p = 0.001), failure to thrive (9% vs. 15% vs. 3%, p = 0.02), and use of gastrostomy tubes (15% vs. 12% vs. 1%, p < 0.001) and topical antibiotics (67% vs. 69% vs. 34%, p < 0.001), while older respondents were more likely to be overweight or obese (6% vs. 0% vs. 51%, p < 0.001) and have difficulty walking (24% vs. 46% vs. 48%, p = 0.04). CONCLUSIONS In the largest international cross-sectional survey of EBS patients conducted, respondents reported extensive disease burden including significant wounding, pain, itch, difficulty walking, and impact on QOL. Age stratified disease manifestations. These findings suggest significant unmet need, and treatment and counseling for EBS patients should consider age-specific differences.

Abstract
Question Is upadacitinib efficacy and safety maintained through 52 weeks of continuous treatment in patients with moderate to severe atopic dermatitis? Findings In this analysis of follow-up data from the large, global, replicate phase 3 Measure Up 1 and Measure Up 2 randomized clinical trials including a total of 1609 patients, once-daily upadacitinib (15 mg or 30 mg) provided durable efficacy with responses maintained through 52 weeks of treatment. No new safety risks were observed. Meaning This follow-up analysis of 2 randomized clinical trials found that continuous upadacitinib treatment showed a favorable longer-term benefit-risk profile in patients with moderate to severe atopic dermatitis. Importance Primary results from the Measure Up 1 and Measure Up 2 studies demonstrated upadacitinib efficacy and safety through 16 weeks in patients with atopic dermatitis. Longer-term outcomes remain unknown. Objective To evaluate long-term (52 weeks) efficacy and safety of upadacitinib treatment in patients with atopic dermatitis. Design, Setting, and Participants Measure Up 1 and Measure Up 2 are ongoing double-blind, placebo-controlled, replicate phase 3 randomized clinical trials that include adults and adolescents with moderate to severe atopic dermatitis at 151 and 154 centers, respectively. Cutoffs for this analysis were December 21, 2020 (Measure Up 1), and January 15, 2021 (Measure Up 2). Interventions Patients were randomized 1:1:1 to receive once-daily oral upadacitinib 15 mg, 30 mg, or placebo. At week 16, patients randomized at baseline to receive upadacitinib 15 mg (273 and 260 patients in Measure Up 1 and Measure Up 2, respectively) and 30 mg (270 and 268 patients) continued assigned treatment; placebo-treated patients were rerandomized 1:1 to receive upadacitinib 15 mg (121 and 120 patients in Measure Up 1 and Measure Up 2, respectively) or 30 mg (123 and 121 patients) in a double-blinded manner. Main Outcomes and Measures Safety and efficacy, including 75% improvement in the Eczema Area and Severity Index and Validated Investigator Global Assessment for Atopic Dermatitis score of clear (0) or almost clear (1) with 2 or greater grades of improvement, were assessed. Results Measure Up 1 and Measure Up 2 included a total of 1609 patients (mean [SD] age, 33.8 [15.6] years; 727 women [45.2%]; 882 men [54.8%]). Efficacy at week 16 was maintained through week 52. At week 52, 75% improvement in the Eczema Area and Severity Index was achieved by 82.0% (95% CI, 77.0%-86.9%) and 79.1% (95% CI, 73.9%-84.4%) of patients continuing the 15-mg dose and 84.9% (95% CI, 80.3%-89.5%) and 84.3% (95% CI, 79.6%-89.0%) of patients continuing the 30-mg dose (for Measure Up 1 and Measure Up 2, respectively); Validated Investigator Global Assessment for Atopic Dermatitis score of clear (0) or almost clear (1) with 2 or greater grades of improvement was achieved by 59.2% (95% CI, 52.9%-65.5%) and 52.6% (95% CI, 46.2%-59.1%) and 62.5% (95% CI, 56.3%-68.7%) and 65.1% (95% CI, 58.9%-71.2%) of patients in the Measure Up 1 and Measure Up 2 studies, respectively. Treatment discontinuation due to adverse events was low overall but was slightly higher for the upadacitinib 30-mg dose. Both upadacitinib doses were well tolerated with no new safety signals. Conclusions and Relevance In this analysis of follow-up data from 2 randomized clinical trials, longer-term treatment of adolescents and adults with moderate to severe atopic dermatitis with upadacitinib demonstrated a favorable benefit-risk profile, with sustained efficacy responses through 52 weeks.

Abstract
BACKGROUNDRecessive dystrophic epidermolysis bullosa (RDEB) patients have mutations in the COL7A1 gene and thus lack functional type VII collagen (C7) protein; they have marked skin fragility and blistering. This single-center phase 1/2a open-label study evaluated the long-term efficacy, safety, and patient-reported outcomes in RDEB patients treated with gene-corrected autologous cell therapy.METHODSAutologous keratinocytes were isolated from participant skin biopsies. Epidermal sheets were prepared from cells transduced with a retrovirus carrying the full-length human COL7A1 gene. These gene-corrected autologous epidermal sheets measured 5 × 7 cm (35 cm2) and were transplanted onto 6 wound sites in each of 7 adult participants (n = 42 sites total) from 2013 to 2017. Participants were followed for 2 to 5 years.RESULTSNo participants experienced any serious related adverse events. Wound healing of 50% or greater by Investigator Global Assessment was present in 95% (36 of 38) of treated wounds versus 0% (0 of 6) of untreated control wounds at 6 months (P < 0.0001). At year 1, 68% (26 of 38) of treated wounds had 50% or greater healing compared with 17% (1 of 6) of control wounds (P = 0.025). At year 2, 71% (27 of 38) of treated wounds had 50% or greater healing compared with 17% (1 of 6) of control wounds (P = 0.019).CONCLUSIONC7 expression persisted up to 2 years after treatment in 2 participants. Treated wounds with 50% or greater healing demonstrated improvement in patient-reported pain, itch, and wound durability. This study provides additional data to support the clinically meaningful benefit of treating chronic RDEB wounds with ex vivo, C7 gene-corrected autologous cell therapy. This approach was safe and promoted wound healing that was associated with improved patient-reported outcomes.TRIAL REGISTRATIONClinicaltrials.gov identifier: NCT01263379.FUNDINGEpidermolysis Bullosa Research Partnership, Epidermolysis Bullosa Medical Research Foundation, NIH R01 AR055914, Office of Research and Development at the Palo Alto Veteran's Affairs Medical Center, and the Dermatology Foundation.

Phase 2 trial of a neurokinin-1 receptor antagonist for the treatment of chronic itch in patients with epidermolysis bullosa: A randomized clinical trial. J Am Acad Dermatol 2019; 82:1415-1421.

Abstract
BACKGROUND Chronic pruritus causes major morbidity in epidermolysis bullosa (EB). The substance P-neurokinin 1 receptor (SP-NK1) pathway is a promising target for treating EB-related pruritus. OBJECTIVE To evaluate the safety and efficacy of the oral NK1 receptor antagonist serlopitant in treating moderate-severe pruritus in EB. METHODS The study randomized 14 patients to serlopitant or placebo for 8 weeks, followed by a 4-week washout and optional open-label extension. The primary end point was change in itch as measured by the Numeric Rating Scale. Secondary end points were change in itch during dressing changes and wound size. RESULTS We observed greater itch reduction with serlopitant, equivalent to a 0.64-point comparative reduction on the 11-point Numeric Rating Scale by week 8, although this failed to meet statistical significance (P = .11). More serlopitant patients achieved ≥3-point reduction compared with placebo (43% vs 14%, P = .35). In post hoc analysis excluding 1 patient with a concurrent seborrheic dermatitis flare, serlopitant achieved significantly greater median itch reduction from baseline by week 4 (-2 points vs 0, P = .01). We observed no statistically significant differences in secondary end points. Serlopitant was well-tolerated. LIMITATIONS Small sample size due to disease rarity. CONCLUSION The potential itch reduction with serlopitant observed in this trial will be pursued by a larger powered trial (NCT03836001).

Abstract
Fibrous papules present clinically as benign, asymptomatic, dome-shaped, flesh colored papules on the face. Histologically, fibrous papules are characterized by fibrous stroma with fibroblasts and dilated blood vessels. Multiple variants of fibrous papules have been reported. Although scattered multinucleated cells in fibrous papules have been well described, we report a fibrous papule with abundant multinucleated ganglion-like giant cells that were immunoreactive with CD34. Recognition of such fibrous papule variants is important to avoid misdiagnosis as potentially more worrisome and/or aggressive melanocytic, soft tissue, or neural lesions that may require more aggressive treatment. Indeed, fibrous papules do not commonly appear on the differential diagnosis for lesions with multinucleated giant cells or ganglion-like cells and consideration should be given to their inclusion in the appropriate clinical setting.

Abstract
Sporadic human basal cell carcinomas (BCC) are generally well managed with current surgical modalities. However, in the subset of high-risk patients predisposed to developing large numbers of BCCs, there is an unmet need for effective, low-morbidity chemoprevention. This population includes fair-skinned patients with extensive sun exposure and those with genodermatoses such as the basal cell nevus (Gorlin) syndrome (BCNS). Tazarotene (Tazorac, Allergan) is a topical retinoid with relative specificity for RAR-β and RAR-γ receptors. We previously demonstrated tazarotene's robust anti-BCC efficacy in Ptch1(+/-) mice, a murine equivalent of BCNS, and others have found it to have some efficacy against sporadic human BCCs. We report here results of a randomized, double-blind, vehicle-controlled study in patients with BCNS evaluating the efficacy of topically applied tazarotene for BCC chemoprevention (N = 34 subjects), along with an open-label trial evaluating tazarotene's efficacy for chemotherapy of BCC lesions (N = 36 subjects) for a maximum follow-up period of 3 years. We found that only 6% of patients had a chemopreventive response and that only 6% of treated BCC target lesions were clinically cured. Our studies provide no evidence for either chemopreventive or chemotherapeutic effect of tazarotene against BCCs in patients with BCNS.

Abstract
Itch is the most common skin disorder in the elderly and frequently diminishes quality of life in this population. The high prevalence of pruritus in elderly patients is attributed in part to the decline in the normal physiology of the advanced aging skin, and reflects poor hydration, impaired skin barrier, and altered neural function, all ultimately contributing to inflammation and pruritus. As the elderly population continues to grow, practitioners need to be aware of how to evaluate and manage pruritus, recognizing the common conditions contributing to itch in elderly patients as well as the challenges of treatment in this group. Ultimately, management of pruritus will require an individually tailored approach that is guided by a patient's general health, severity of symptoms, and the potential adverse effects of itch therapies.

Tumor angiogenesis as a target for dietary cancer prevention. JOURNAL OF ONCOLOGY 2011; 2012:879623.

Abstract
Between 2000 and 2050, the number of new cancer patients diagnosed annually is expected to double, with an accompanying increase in treatment costs of more than $80 billion over just the next decade. Efficacious strategies for cancer prevention will therefore be vital for improving patients' quality of life and reducing healthcare costs. Judah Folkman first proposed antiangiogenesis as a strategy for preventing dormant microtumors from progressing to invasive cancer. Although antiangiogenic drugs are now available for many advanced malignancies (colorectal, lung, breast, kidney, liver, brain, thyroid, neuroendocrine, multiple myeloma, myelodysplastic syndrome), cost and toxicity considerations preclude their broad use for cancer prevention. Potent antiangiogenic molecules have now been identified in dietary sources, suggesting that a rationally designed antiangiogenic diet could provide a safe, widely available, and novel strategy for preventing cancer. This paper presents the scientific, epidemiologic, and clinical evidence supporting the role of an antiangiogenic diet for cancer prevention.

Abstract
The effects of vibrational excitation on the Cl+CD(4) reaction are investigated by preparing three nearly isoenergetic vibrational states: mid R:3000 at 6279.66 cm(-1), |2100> at 6534.20 cm(-1), and |1110> at 6764.24 cm(-1), where |D(1)D(2)D(3)D(4)> identifies the number of vibrational quanta in each C-D oscillator. Vibrational excitation of the perdeuteromethane is via direct infrared pumping. The reaction is initiated by photolysis of molecular chlorine at 355 nm. The nascent methyl radical product distribution is measured by 2+1 resonance-enhanced multiphoton ionization at 330 nm. The resulting CD(3) state distributions reveal a preference to remove all energy available in the most excited C-D oscillator. Although the energetics are nearly identical, the authors observe strong mode specificity in which the CD(3) state distributions markedly differ between the three Cl-atom reactions. Reaction with CD(4) prepared in the |3000> mode leads to CD(3) products populated primarily in the ground state, reaction with CD(4) prepared in the |2100> mode leads primarily to CD(3) with one quantum of stretch excitation, and reaction with CD(4) prepared in the |1110> mode leads primarily to CD(3) with one quantum of C-D stretch excitation in two oscillators. There are some minor deviations from this behavior, most notably that the Cl atom is able to abstract more energy than is available in a single C-D oscillator, as in the case of |2100>, wherein a small population of ground-state CD(3) is observed. These exceptions likely result from the mixings between different second overtone stretch combination bands. They also measure isotropic and anisotropic time-of-flight profiles of CD(3) (nu(1)=1,2) products from the Cl+CD(4) |2100> reaction, providing speed distributions, spatial anisotropies, and differential cross sections that indicate that energy introduced as vibrational energy into the system essentially remains as such throughout the course of the reaction.

Abstract
The importance of reactive trajectories straying far from the minimum energy path is demonstrated for the bimolecular reaction H + HBr --> H2(v', j') + Br at 53 kcal/mol collision energy. Product quantum state distributions are measured and calculated using the quasi-classical trajectory technique, and the calculations indicate that highly internally excited H2 products result from indirect reactive trajectories with bent transition states. A general argument is made suggesting that reaction products with internal energy exceeding a kinematic constraint can, in general, be attributed to reactive collisions straying far from the minimum energy path.
