RESUMEN
Sarcoidosis is a chronic granulomatous disease predominantly affecting the lungs and inducing significant morbidity and elevated mortality rate. The etiology of the disease is unknown but may involve exposure to an antigenic agent and subsequent inflammatory response resulting in granuloma formation. Various environmental and occupational risk factors have been suggested by previous observations, such as moldy environments, insecticides, and bird breeding. Our study investigated the association of air pollution with diagnosis of sarcoidosis using a case-control design. Penn State Health electronic medical records from 2005 to 2018 were examined for adult patients with (cases) and without (controls) an International Classification of Disease (ICD)-9 or -10 code for sarcoidosis. Patient addresses were geocoded and 24-hr residential-level air pollution concentrations were estimated using spatio-temporal models of particulate matter <2.5 µm (PM2.5), ozone, and PM2.5 elemental carbon (EC) and moving averages calculated. In total, 877 cases and 34,510 controls were identified. Logistic regression analysis did not identify significant associations between sarcoidosis incidence and air pollution exposure estimates. However, the odds ratio (OR) for EC for exposures occurring 7-10 years prior did approach statistical significance, and ORs exhibited an increasing trend for longer averaging periods. Data suggested a latency period of more than 6 years for PM2.5 and EC for reasons that are unclear. Overall, results for PM2.5 and EC suggest that long-term exposure to traffic-related air pollution may contribute to the development of sarcoidosis and emphasize the need for additional research and, if the present findings are substantiated, for public health interventions addressing air quality as well as increasing disease surveillance in areas with a large burden of PM2.5 and EC.

INTRODUCTION: Herpes zoster increases stroke and myocardial infarction risk. The objective of this study is to evaluate the impact of live attenuated zoster vaccination on stroke and myocardial infarction risk in patients at risk of zoster, including those with hypertension, diabetes mellites, obesity, hypercholesterolemia, chronic kidney disease, chronic obstructive pulmonary disease, emphysema, asthma, and chronic liver disease. METHODS: This is a retrospective cohort study utilizing continuous de-identified claims data from the IBM MarketScan Commercial Claims and Encounters Database (collected from 2005-2018) containing data for 200 million commercially insured Americans. Participants included 27,093 adults vaccinated against zoster with at least 5 years of continuous enrollment, age and sex-matched 1:5 with unvaccinated controls. OR, risk difference, and the number needed to treat evaluated the effect of vaccination on stroke and myocardial infarction while controlling for relevant comorbidities. RESULTS: Over the period of 5 years, proportions of myocardial infarction (1.29% vs 1.82%; p<0.05) and stroke (1.61% vs 2.20%; p<0.05) were lower in vaccinated versus unvaccinated individuals, respectively, controlling for age and sex, with the greatest benefit for people with diabetes (stroke OR=0.64, 95% CI=0.58, 0.71; myocardial infarction OR=0.63, 95% CI=0.57, 0.71). Although hypertension and chronic obstructive pulmonary disease had the highest odds of stroke and myocardial infarction, vaccination still provided significant risk-reduction (hypertension: stroke 0.75 [0.68, 0.83], myocardial infarction 0.73 [0.65, 0.81]; chronic obstructive pulmonary disease: stroke 0.75 [0.68, 0.83], myocardial infarction 0.74 [0.66, 0.83]). CONCLUSIONS: Live attenuated zoster vaccination is associated with lower risk of stroke and myocardial infarction in adults with at-risk comorbidities, controlling for age and sex. Vaccination may provide cardiovascular benefits beyond zoster prevention.

BACKGROUND: Herpes zoster increases the risk for stroke and myocardial infarction. Zoster vaccination's impact on this risk is understudied. This retrospective work sought to determine if prophylactic herpes zoster vaccination may reduce the risk of stroke, myocardial infarction, and/or mortality. METHODS: A cohort analysis utilized TriNetX, a national, federated database. In one analysis, patients who received 2 doses of recombinant zoster vaccine (RZV) were compared to adults without RZV. A 1:1 propensity-score match analysis was conducted to adjust for demographics and comorbidities in calculating adjusted relative risks (aRR) with 95% confidence intervals. First-time incidences for myocardial infarction, stroke, and mortality were assessed after 3 years. A subgroup analysis between RZV and zoster vaccine live (ZVL) was also assessed. RESULTS: Matched cohorts of 7,657 patients revealed that adults who received 2 doses of RZV were at lower risk of MI (aRR [95% CI]) = (0.73 [0.55, 0.96]) and mortality (0.7 [0.57, 0.88]) while having similar risk for stroke (0.97 [0.75, 1.26]). Further subgroup analysis also revealed a reduced risk of 3-year mortality when compared to the ZVL cohort (0.84 [0.74, 0.95]). Sample size and comorbidities included in the analysis were limited by using a large database. CONCLUSIONS: RZV reduces the 3-year risk for myocardial infarction and mortality.

Dermatomyositis (DM) is a rare idiopathic inflammatory myopathy (IIM) associated with an increased risk for malignancy. Although cancer screening is recommended, no consensus guidelines currently exist. Whole-body positron emission tomography/ computed tomography (PET/CT) has similar cost and efficacy to a more traditional conventional cancer screening panel (CSP). Our study sought to characterize patients' perspective of cancer screening and the indirect costs to patients. We conducted a survey of patients recently diagnosed with DM who were undergoing or had recently undergone a CSP. Patient values and indirect costs need to be considered in choosing a screening modality. This study contributes to a greater understanding of patients' experience of cancer screening in DM, which should be taken into consideration when developing consensus guidelines for cancer screening.

BACKGROUND: Hidradenitis suppurativa (HS) is a debilitating inflammatory skin disease characterized by painful nodules, drainage and scarring in skin folds. Injectable adalimumab is the only drug approved by the US Food and Drug Administration for the treatment of HS. Although systemic Janus kinase (JAK) inhibitors show promise, serious side-effects have been reported. There are no highly effective topical treatments for HS; furthermore, the contribution of epidermal keratinocytes to the intense inflammation has largely been unexplored. OBJECTIVES: We investigated the role of keratinocytes and epidermal immune cells in HS inflammation at all Hurley stages of disease severity. We aimed to determine whether ruxolitinib can mitigate inflammation from keratinocytes and to develop a better understanding of how topical therapeutics might benefit patients with HS. METHODS: We used skin samples from 87 patients with HS (Hurley stages I-III) and 39 healthy controls to compare keratinocyte- and immune cell-driven epidermal inflammation, in addition to the response of lesional HS keratinocytes to treatment with interferon (IFN)-γ and ruxolitinib. We used haematoxylin and eosin staining, immunohistochemistry, immunoblotting and quantitative reverse-transcription polymerase chain reaction assessments in whole skin, isolated epidermis, and cultured keratinocytes from healthy controls and both nonlesional and lesional HS skin to identify and define epidermal and keratinocyte-mediated inflammation in HS and how this may be targeted by therapeutics. RESULTS: HS lesional keratinocytes autonomously secreted high levels of chemokines, such as CCL2, CCL3 and CXCL3, which recruited neutrophils, CD8 T cells, and natural killer cells to the epidermis. Keratinocytes were the dominant source of tumour necrosis factor-α and interleukin (IL)-6 in HS lesions with little to no contribution from underlying dermal immune cells. In the presence of IFN-γ, which is dependent on immune cell infiltrate in vivo, keratinocytes expressed increased levels of additional cytokines including IL-1ß, IL-12, IL-23 and IL-36γ. The JAK inhibitor ruxolitinib mitigated the expression of inflammatory cytokines and chemokines in HS lesional keratinocytes, thus providing a rationale for future study as a topical treatment for HS. CONCLUSIONS: This study demonstrates that keratinocytes actively recruit immune cells to HS epidermis and interactions between these cells drive a broad inflammatory profile in HS epidermis. Targeting epidermal inflammation in HS with novel topical formulations may be highly efficacious with reduced systemic side-effects.

BACKGROUND: Skin biopsies are crucial for the diagnosis of many cutaneous pathologies, yet specimen adequacy is essential for definitive diagnosis. Recent literature has noted a trend in decreasing biopsy size over time, which has created concern over implications regarding adequacy for diagnosis. METHODS: This study sought to evaluate if clinician training length or type of residency training impacted the average biopsy size and sample adequacy. Dermatopathology reports for shave biopsies between January 1, 2021, and June 30, 2021, at Penn State Health were queried through PathNet, the software application for pathology reports in this health system's electronic medical record system. Biopsy dimensions, volume, diagnosis, location, clinician training level, and descriptions of evaluation of deeper sections (recuts) and superficial sampling were recorded for each biopsy. Basic statistical calculations were performed to assess the mean and standard deviation for biopsy sizes per clinician group. RESULTS: Differences in biopsy size between training levels were statistically significant despite qualitatively similar biopsy locations and final diagnosis categories for each clinician training group. After evaluating measures for sample adequacy, our data showed significantly smaller biopsies; however, overall frequencies were minimal. Additionally, more inadequate specimens were noted for clinician groups with the least amount of dermatology experience. CONCLUSIONS: The results of this study identify a correlation with decreasing biopsy size amidst increased experience in dermatology training but find no evidence to support that this trend currently threatens sample adequacy.

Burnout is increasing in all fields of medicine, including dermatology. The coronavirus disease 2019 (COVID-19) pandemic presented new and additional challenges for dermatologists. Objective: Dermatologists of different ages, areas of expertise, and practice settings were convened in 5 focus group to describe the impact of the COVID-19 pandemic on their clinical practice, working environment, and personal lives. Methods: Qualitative analysis of the discussions w\s performed on the result of the 5 focus groups of dermatologists (n = 22). Groups were prompted with questions relating to their jobs, personal lives, teledermatology, and pandemic. Responses were recorded, transcribed, deidentified, and coded for recurring themes. The focus groups occurred via a secure videoconferencing platform between December 2020 and January 2021. All participants were currently practicing dermatology in a variety of setting including academic institutions, private practices, and multiple practice types. General dermatologists, residents in training, dermatologic surgeons, dermatopathologists, and dermatologists with significant administrative or educational duties were included. Results: We identified 4 main themes from the focus group discussions regarding dermatologist and physician wellbeing during the COVID-19 pandemic: (1) adjusting to new administrative, staffing, and educational demands; (2) integration of work as a dermatologist with family life; (3) new technologies such as teledermatology; and (4) adjusting to change with redefining personal and professional priorities. Limitations: The small number of participants in our convenience cohort disproportionately represented academic dermatologists. Impacts of regional COVID-19 vaccination rates and ideological differences in different geographical locations were not assessed. All of our participants were located in the United States. Physicians severely impacted by health or financial concerns may not have been able to participate in our study. We did not have a comparison group and did not measure or assess burnout in individual participants. Conclusion: During the COVID-19 pandemic, there were common changes and stressors that dermatologists experienced, which affected physician wellbeing. Identifying and addressing these changes could offer the opportunity to improve the wellbeing of dermatologists.
RESUMEN
Dermoscopy is a noninvasive technique that allows in vivo magnification of the skin structures and helps in visualizing microscopic features that are imperceptible to the naked eye. Dermoscopy is not a substitute for biopsy and histopathologic evaluation, but is an important tool that can help increase diagnostic sensitivity and specificity of cutaneous lesions. Dermoscopy increases the diagnostic sensitivity compared with naked eye examination. A significant improvement in diagnostic accuracy for benign and malignant lesions has been reported among family medicine physicians after an introductory training course on dermoscopy.
