Protecting Cardiovascular Health From Wildfire Smoke.

Wildfire smoke is a rapidly growing threat to global cardiovascular health. We review the literature linking wildfire smoke exposures to cardiovascular effects. We find substantial evidence that short-term exposures are associated with key cardiovascular outcomes, including mortality, hospitalization, and acute coronary syndrome. Wildfire smoke exposures will continue to increase over the majority of Earth's surface. For example, the United States alone has experienced a 5-fold increase in annual area burned since 1972, with 82 million individuals estimated to be exposed to wildfire smoke by midcentury. The associated rise in excess morbidity and mortality constitutes a growing global public health crisis. Fortunately, the effect of wildfire smoke on cardiovascular health is modifiable at the individual and population levels through specific interventions. Health systems therefore have an opportunity to help safeguard patients from smoke exposures. We provide a roadmap of evidence-based interventions to reduce risk and protect cardiovascular health. Key interventions include preparing health systems for smoke events; identifying and educating vulnerable patients; reducing outdoor activities; creating cleaner air environments; using air filtration devices and personal respirators; and aggressive management of chronic diseases and traditional risk factors. Further research is needed to test the efficacy of interventions on reducing cardiovascular outcomes.

Developing a Clinical Approach to Air Pollution and Cardiovascular Health.

Nearly 3 billion people are exposed to household air pollution emitted from inefficient cooking and heating stoves, and almost the entire global population is exposed to detectable levels of outdoor air pollution from traffic, industry, and other sources. Over 3 million people die annually of ischemic heart disease or stroke attributed to air pollution, more than from traditional cardiac risk factors such as obesity, diabetes mellitus, or smoking. Clinicians have a role to play in reducing the burden of pollution-attributable cardiovascular disease. However, there currently exists no clear clinical approach to this problem. Here, we provide a blueprint for an evidence-based clinical approach to assessing and mitigating cardiovascular risk from exposure to air pollution. We begin with a discussion of the global burden of pollution-attributable cardiovascular disease, including a review of the mechanisms by which particulate matter air pollution leads to cardiovascular outcomes. Next, we offer a simple patient-screening tool using known risk factors for pollution exposure. We then discuss approaches to quantifying air pollution exposures and cardiovascular risk, including the development of risk maps for clinical catchment areas. We review a collection of interventions for household and outdoor air pollution, which clinicians can tailor to patients and populations at risk. Finally, we identify future research needed to quantify pollution exposures and validate clinical interventions. Overall, we demonstrate that clinicians can be empowered to mitigate the global burden of cardiovascular disease attributable to air pollution.

Cutaneous carcinosarcoma: a series of six cases and a review of the literature.

BACKGROUND: Cutaneous carcinosarcoma is a rare tumor with distinct malignant epithelial and mesenchymal cell populations. The histologic subtypes of epithelial and mesenchymal components in cutaneous carcinosarcoma are variable, as an assortment of carcinomatous and sarcomatous patterns have been described in the literature. METHODS: Clinical information was obtained from patient charts and archival slides were retrieved and reviewed. RESULTS: We present a novel series of six distinct cases of cutaneous carcinosarcoma and review the literature. Our cases consisted of basal cell, pilomatrical, squamous cell, and trichoblastic variants. These cases occurred in elderly men on sun exposed skin with treatment and follow up was available for 4 of 6 cases. The four cases were treated with Mohs micrographic surgery with mean follow up of nine months. CONCLUSION: We report six cases of cutaneous carcinosarcoma with distinctive clinical and histologic characterization not previously described in a single series.

Mohs appropriate use criteria: retrospectively applied to nonmelanoma skin cancers at a single academic center.

BACKGROUND: In September 2012, appropriate use criteria (AUC) for Mohs micrographic surgery (MMS) were released by a collaboration of dermatology organizations including the American College of Mohs Surgery. OBJECTIVE: The group sought to determine adherence to the Mohs AUC at the academic institution. MATERIALS AND METHODS: The authors performed a retrospective chart review of all nonmelanoma skin cancers (NMSCs) treated within the University of Utah, Department of Dermatology, from January through March of 2012. They applied the Mohs AUC to analyze these cases. RESULTS: In total, the authors identified 724 patients and 1,026 cases of NMSCs, including 557 (54.3%) basal cell carcinomas and 469 (45.7%) squamous cell carcinomas. Of the 1,026 NMSCs, 350 (34.1%) were treated with MMS. Of these cases treated with MMS, there were 339 cases (96.9%) deemed appropriate, 4 (1.1%) uncertain, and 7 (2.0%) inappropriate per AUC. Also examined were 611 cases treated with modalities other than MMS, of which 60.7% would have met AUC for MMS. CONCLUSION: In a 3-month review of all NMSC cases at the academic center, there is a low percentage of cases performed that are inappropriate for MMS by AUC. At the institution, there is a large percentage of NMSC that meet AUC but are treated by other modalities. The use is highly appropriate for MMS, and these data suggest possible underutilization of MMS for certain NMSCs. Further studies are required to determine the effectiveness of other treatment modalities for NMSC that meet Mohs AUC.

Opioid prescribing patterns after Mohs micrographic surgery and standard excision: a survey of American Society for Dermatologic Surgery members and a chart review at a single institution.

BACKGROUND: Little is known about postoperative opioid prescribing patterns among dermatologic surgeons. OBJECTIVE: To better understand postoperative opioid prescribing patterns among dermatologic surgeons in the United States. MATERIALS AND METHODS: Two-part analysis consisting of a retrospective chart review of 233 dermatologic surgery patients at a single institution and an e-mail survey of American Society for Dermatologic Surgery (ASDS) members. RESULTS: (1) Retrospective review: 35% (82/233) of the patients received an opioid prescription. Larger defect size, repair of the defect, perioral and nasal site, and surgeon A or B performing surgery predicted opioid prescription. (2) E-mail survey: 556 ASDS members practicing within the United States responded. Sixty-four percent (357/556) reported prescribing opioids after ≤10% of cases. Surgeons younger than 55 years old, male surgeons, and surgeons in the southern and western United States were more likely to prescribe opioids after >10% of cases. Seventy-six percent (397/520) believed patients used ≤50% of the opioid pills prescribed. CONCLUSION: The retrospective review suggests that opioid prescribing is predicted by characteristics of the surgery (i.e., size, defect repair type, and anatomic location) and characteristics of the surgeon (i.e., age, sex, and practice location) with significant heterogeneity in prescribing habits. The national survey results raise the possibility that patients might not take all prescribed opioid pills after dermatologic surgery. Further investigation is warranted to determine how patients are actually using prescription pain pills to balance pain control with patient safety.

Cardiac Magnetic Resonance for Structural Aortic Valve Stenosis Procedures.

The number of structural aortic valve procedures has increased significantly in recent years. Pre-procedural planning and follow-up with noninvasive testing are essential. Although cardiac magnetic resonance (CMR) is the gold standard for assessing left ventricular mass, volume, and function, it is not performed routinely in patients undergoing structural interventions. CMR can provide useful information for pre- and post-procedural assessment, including quantification of cardiac function, myocardial assessment, grading of the severity of valvular heart disease, and evaluation of extracardiac anatomy while avoiding the limitations of other non-invasive modalities. Here, we review the use cases, future perspectives, and limitations of CMR for patients undergoing structural aortic valve procedures.

Left Ventricular Remodeling in Patients with Low Flow Aortic Stenosis Undergoing Transcatheter Aortic Valve Replacement.

Low-flow (LF) aortic stenosis (AS) is common among older adults and associated with worse outcomes than AS with normal stroke volume. It is unknown whether left ventricular (LV) remodeling identifies patients with LF AS at higher risk of complications. LV remodeling was evaluated in 463 patients with severe LF AS referred for transcatheter aortic valve replacement (TAVR) and classified as adaptive (normal geometry and concentric remodeling) or maladaptive (concentric and eccentric hypertrophy) using the American Society of Echocardiography gender-specific criteria. Of these, the 390 patients who underwent TAVR were followed for the end points of heart failure (HF) hospitalization and all-cause mortality. The mean patient age was 79 (74.5 to 84) years. LV remodeling was adaptive in 57.4% (62 normal geometry, 162 concentric remodeling) and maladaptive in 42.6% (127 concentric hypertrophy, 39 eccentric hypertrophy). During a median follow-up of 3 years, 45 patients (11.5%) were hospitalized for HF and 73 (18.7%) died. After adjustment for widely used echocardiographic parameters, maladaptive remodeling was independently associated with HF hospitalization and death (adjusted hazard ratio 1.75, confidence interval 1.03 to 3.00). There was no significant difference between men and women in the association of maladaptive LV remodeling with the composite outcome (p = 0.40 for men and p = 0.06 for women). In conclusion, in patients with LF AS, maladaptive LV remodeling before TAVR is independently associated with higher incidences of postprocedural HF rehospitalization and death in both men and women. Assessment of LV remodeling has prognostic value over and above LV ejection fraction and may improve risk stratification for patients with LF AS.

Advances in Coronary Computed Tomographic Angiographic Imaging of Atherosclerosis for Risk Stratification and Preventive Care.

The diagnostic evaluation of coronary artery disease is undergoing a dramatic transformation with a new focus on atherosclerotic plaque. This review details the evidence needed for effective risk stratification and targeted preventive care based on recent advances in automated measurement of atherosclerosis from coronary computed tomography angiography (CTA). To date, research findings support that automated stenosis measurement is reasonably accurate, but evidence on variability by location, artery size, or image quality is unknown. The evidence for quantification of atherosclerotic plaque is unfolding, with strong concordance reported between coronary CTA and intravascular ultrasound measurement of total plaque volume (r >0.90). Statistical variance is higher for smaller plaque volumes. Limited data are available on how technical or patient-specific factors result in measurement variability by compositional subgroups. Coronary artery dimensions vary by age, sex, heart size, coronary dominance, and race and ethnicity. Accordingly, quantification programs excluding smaller arteries affect accuracy for women, patients with diabetes, and other patient subsets. Evidence is unfolding that quantification of atherosclerotic plaque is useful to enhance risk prediction, yet more evidence is required to define high-risk patients across varied populations and to determine whether such information is incremental to risk factors or currently used coronary computed tomography techniques (eg, coronary artery calcium scoring or visual assessment of plaque burden or stenosis). In summary, there is promise for the utility of coronary CTA quantification of atherosclerosis, especially if it can lead to targeted and more intensive cardiovascular prevention, notably for those patients with nonobstructive coronary artery disease and high-risk plaque features. The new quantification techniques available to imagers must not only provide sufficient added value to improve patient care, but also add minimal and reasonable cost to alleviate the financial burden on our patients and the health care system.

Results of an investigator-initiated single-blind split-face comparison of photodynamic therapy and 5% imiquimod cream for the treatment of actinic keratoses.

BACKGROUND: Topical photodynamic therapy (PDT) with aminolevulinic acid (ALA) and 5% imiquimod cream are effective therapies for the treatment of actinic keratoses (AKs), but no split-face studies directly comparing these treatment options are available in the literature. OBJECTIVE: To compare the efficacy and tolerability of ALA-PDT and imiquimod 5% cream for the treatment of AKs. RESULTS: Sixty-one patients were enrolled from the Salt Lake City Veterans Affairs Hospital; 51 completed the study and were included in the analysis. All patients were randomized to receive half of a sachet of imiquimod 5% cream twice weekly on half of their face and two sessions of PDT with 20% solution of ALA applied for 1 hour to the other side of the face. The 75% AK clearance rate was 34.6% for ALA-PDT and 25% for imiquimod 5% cream (p = .30). The mean reduction in AK count was 59.2% for ALA-PDT and 41.4% for imiquimod 5% cream (p = .002). Dermatology Life Quality Index (DLQI) scores were assessed for each treatment modality at week 4 and were 1.95 and 1.38, respectively (p = .20). LIMITATIONS: The sample size was small, and patients applied a small amount of imiquimod 5% cream (half a sachet) to a large surface area. CONCLUSION: There was no statistically significant difference in treatment response when the 100% or 75% clearance rate cutoff was used, but our secondary outcome suggests that two sessions of ALA-PDT is superior to imiquimod 5% cream for the treatment of AKs. There was no statistically significant difference in effect on quality of life as assessed using the DLQI.

Modelling strategic interventions in a population with a total fertility rate of 8.3: a cross-sectional study of Idjwi Island, DRC.

BACKGROUND: Idjwi, an island of approximately 220,000 people, is located in eastern DRC and functions semi-autonomously under the governance of two kings (mwamis). At more than 8 live births per woman, Idjwi has one of the highest total fertility rates (TFRs) in the world. Rapid population growth has led to widespread environmental degradation and food insecurity. Meanwhile family planning services are largely unavailable. METHODS: At the invitation of local leaders, we conducted a representative survey of 2,078 households in accordance with MEASURE DHS protocols, and performed ethnographic interviews and focus groups with key informants and vulnerable subpopulations. Modelling proximate determinates of fertility, we evaluated how the introduction of contraceptives and/or extended periods of breastfeeding could reduce the TFR. RESULTS: Over half of all women reported an unmet need for spacing or limiting births, and nearly 70% named a specific modern method of contraception they would prefer to use; pills (25.4%) and injectables (26.5%) were most desired. We predicted that an increased length of breastfeeding (from 10 to 21 months) or an increase in contraceptive prevalence (from 1% to 30%), or a combination of both could reduce TFR on Idjwi to 6, the average desired number of children. Increasing contraceptive prevalence to 15% could reduce unmet need for contraception by 8%. CONCLUSIONS: To meet women's need and desire for fertility control, we recommend adding family planning services at health centers with NGO support, pursuing a community health worker program, promoting extended breastfeeding, and implementing programs to end sexual- and gender-based violence toward women.

Case report: Paravalvular regurgitation post transcatheter aortic valve replacement: When in doubt choose cardiac magnetic resonance.

Paravalvular leak (PVL) is a common complication following transcatheter aortic valve replacement (TAVR). Significant PVL is associated with adverse prognosis, but may be challenging to assess accurately. We report the case of an 81-year-old man with shortness of breath 5 months post TAVR. Echocardiography classified PVL as either moderate or severe depending on the parameter utilized, while angiography found only mild PVL. Cardiac magnetic resonance allowed an exact quantification of regurgitant flow volume, classified as clinically and hemodynamically significant. This case highlights the role of multimodality imaging assessment including cardiac magnetic resonance for a more accurate assessment of PVL severity, especially when other imaging modalities show discordant results.

Spatial environmental factors predict cardiovascular and all-cause mortality: Results of the SPACE study.

BACKGROUND: Environmental exposures account for a growing proportion of global mortality. Large cohort studies are needed to characterize the independent impact of environmental exposures on mortality in low-income settings. METHODS: We collected data on individual and environmental risk factors for a multiethnic cohort of 50,045 individuals in a low-income region in Iran. Environmental risk factors included: ambient fine particular matter air pollution; household fuel use and ventilation; proximity to traffic; distance to percutaneous coronary intervention (PCI) center; socioeconomic environment; population density; local land use; and nighttime light exposure. We developed a spatial survival model to estimate the independent associations between these environmental exposures and all-cause and cardiovascular mortality. FINDINGS: Several environmental factors demonstrated associations with mortality after adjusting for individual risk factors. Ambient fine particulate matter air pollution predicted all-cause mortality (per µg/m3, HR 1.20, 95% CI 1.07, 1.36) and cardiovascular mortality (HR 1.17, 95% CI 0.98, 1.39). Biomass fuel use without chimney predicted all-cause mortality (reference = gas, HR 1.23, 95% CI 0.99, 1.53) and cardiovascular mortality (HR 1.36, 95% CI 0.99, 1.87). Kerosene fuel use without chimney predicted all-cause mortality (reference = gas, HR 1.09, 95% CI 0.97, 1.23) and cardiovascular mortality (HR 1.19, 95% CI 1.01, 1.41). Distance to PCI center predicted all-cause mortality (per 10km, HR 1.01, 95% CI 1.004, 1.022) and cardiovascular mortality (HR 1.02, 95% CI 1.004, 1.031). Additionally, proximity to traffic predicted all-cause mortality (HR 1.13, 95% CI 1.01, 1.27). In a separate validation cohort, the multivariable model effectively predicted both all-cause mortality (AUC 0.76) and cardiovascular mortality (AUC 0.81). Population attributable fractions demonstrated a high mortality burden attributable to environmental exposures. INTERPRETATION: Several environmental factors predicted cardiovascular and all-cause mortality, independent of each other and of individual risk factors. Mortality attributable to environmental factors represents a critical opportunity for targeted policies and programs.

Sudden Cardiac Arrest in an Adult with Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA): Case Report.

INTRODUCTION: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare coronary artery anomaly that carries 90% mortality in the first year of life when left untreated. The diagnosis of ALCAPA is rare in adulthood, and it includes a broad spectrum of clinical manifestations, including sudden cardiac death (SCD). CASE REPORT: We report a rare case of resuscitated sudden cardiac arrest in a 55-year-old female, who was diagnosed with ALCAPA and underwent successful surgical correction and implantable cardioverter defibrillator (ICD) implantation for secondary prevention. DISCUSSION: ALCAPA diagnosis is not confined to childhood, and it represents a rare cause of life-threatening arrhythmias and SCD in the adult population. Surgical correction is recommended, regardless of age, presence of symptoms or inducible myocardial ischemia. Multimodality imaging is crucial for diagnosis, management planning and follow up. Assessment of the risk of recurrent ventricular arrhythmias, despite full revascularization, should be performed in all adults with ALCAPA. Myocardial scar detected via late gadolinium enhancement represents a potential irreversible substrate for ventricular arrhythmias, and it provides additional information to evaluate indication of an ICD for secondary prevention.

Clean Air, Smart Cities, Healthy Hearts: Action on Air Pollution for Cardiovascular Health.

More than twenty percent of all cardiovascular disease (CVD) deaths are caused by air pollution - more than three million deaths every year - and these numbers will continue to rise unless the global community takes action. Nine out of ten people worldwide breathe polluted air, which disproportionately affects those living in low-resource settings. The World Heart Federation (WHF) is committed to reducing the impact of air pollution on people's health and has made this a priority area of its global advocacy efforts. In pursuit of this goal, WHF has formed an Air Pollution Expert Group to inform action on air pollution for CVD health and recommend changes to public health policy. This policy paper lays out the health impacts of air pollution, examines its position on the global policy agenda, demonstrates its relevance to the cardiovascular community, and proposes actionable policy measures to mitigate this deadly risk factor to health. The paper considers the important roles to be played by the Members of WHF, including scientific societies and the physicians that constitute them, heart health foundations, and patient advocacy groups. The paper concludes with a detailed table of recommendations for the various sub-target groups at the global, national, local, and patient level.

Atrial Fibrillation in Patients Hospitalized With COVID-19: Incidence, Predictors, Outcomes, and Comparison to Influenza.

OBJECTIVES: The goal of this study is to determine the incidence, predictors, and outcomes of atrial fibrillation (AF) or atrial flutter (AFL) in patients hospitalized with coronavirus disease-2019 (COVID-19). BACKGROUND: COVID-19 results in increased inflammatory markers previously associated with atrial arrhythmias. However, little is known about their incidence or specificity in COVID-19 or their association with outcomes. METHODS: This is a retrospective analysis of 3,970 patients admitted with polymerase chain reaction-positive COVID-19 between February 4 and April 22, 2020, with manual review performed of 1,110. The comparator arm included 1,420 patients with influenza hospitalized between January 1, 2017, and January 1, 2020. RESULTS: Among 3,970 inpatients with COVID-19, the incidence of AF/AFL was 10% (n = 375) and in patients without a history of atrial arrhythmias it was 4% (n = 146). Patients with new-onset AF/AFL were older with increased inflammatory markers including interleukin 6 (93 vs. 68 pg/ml; p < 0.01), and more myocardial injury (troponin-I: 0.2 vs. 0.06 ng/ml; p < 0.01). AF and AFL were associated with increased mortality (46% vs. 26%; p < 0.01). Manual review captured a somewhat higher incidence of AF/AFL (13%, n = 140). Compared to inpatients with COVID-19, patients with influenza (n = 1,420) had similar rates of AF/AFL (12%, n = 163) but lower mortality. The presence of AF/AFL correlated with similarly increased mortality in both COVID-19 (relative risk: 1.77) and influenza (relative risk: 1.78). CONCLUSIONS: AF/AFL occurs in a subset of patients hospitalized with either COVID-19 or influenza and is associated with inflammation and disease severity in both infections. The incidence and associated increase in mortality in both cohorts suggests that AF/AFL is not specific to COVID-19, but is rather a generalized response to the systemic inflammation of severe viral illnesses.

Use of physician assistants in Mohs micrographic surgery: a survey of fellowship-trained Mohs micrographic surgeons.

BACKGROUND: An increasing number of dermatologists are using physician assistants (PAs) in their practices. A lack of information regarding the use of PAs in Mohs micrographic surgery (MMS) served as the driving force for this research. OBJECTIVES: To quantify the extent to which Mohs surgeons are using PAs in MMS. METHODS: Five hundred seventy-six fellows of the American College of Mohs Surgery were sent surveys in the mail in January 2009. The survey was focused on what percentage of Mohs surgeons are using PAs and how those PAs are being used. RESULTS: One hundred forty-three of the 576 surgeons surveyed (24.8%) responded; 43 of those (30.1%) currently employed one or more PAs; and of those 43, 15 (34.9%) reported that PAs in their practice perform preoperative consults, 25 (58.1%) reported that PAs perform postoperative follow-up, 18 (41.9%) reported that PAs were participating in some aspect of repairs, and 35 (81.4%) reported that PAs were seeing general dermatology patients. CONCLUSION: Mohs surgeons are using PAs for perioperative care, as well as seeing general dermatology patients. A smaller percentage of Mohs surgeons are using PAs to perform portions of MMS or the consequent repairs.

Cardiogenic Shock and Mitral Valve Chord Rupture: A Rare Presentation of Libman-Sacks Endocarditis.

Distinguishing Libman-Sacks endocarditis from other valvular heart disease etiologies has important implications for management. We present a case of a 23-year-old man who presented in extremis with fever and cardiogenic shock caused by Libman-Sacks endocarditis with associated mitral valve chord rupture. (Level of Difficulty: Beginner.).

Malignant Arrhythmias in Patients With COVID-19: Incidence, Mechanisms, and Outcomes.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) who develop cardiac injury are reported to experience higher rates of malignant cardiac arrhythmias. However, little is known about these arrhythmias-their frequency, the underlying mechanisms, and their impact on mortality. METHODS: We extracted data from a registry (NCT04358029) regarding consecutive inpatients with confirmed COVID-19 who were receiving continuous telemetric ECG monitoring and had a definitive disposition of hospital discharge or death. Between patients who died versus discharged, we compared a primary composite end point of cardiac arrest from ventricular tachycardia/fibrillation or bradyarrhythmias such as atrioventricular block. RESULTS: Among 800 patients with COVID-19 at Mount Sinai Hospital with definitive dispositions, 140 patients had telemetric monitoring, and either died (52) or were discharged (88). The median (interquartile range) age was 61 years (48-74); 73% men; and ethnicity was White in 34%. Comorbidities included hypertension in 61%, coronary artery disease in 25%, ventricular arrhythmia history in 1.4%, and no significant comorbidities in 16%. Compared with discharged patients, those who died had elevated peak troponin I levels (0.27 versus 0.02 ng/mL) and more primary end point events (17% versus 4%, P=0.01)-a difference driven by tachyarrhythmias. Fatal tachyarrhythmias invariably occurred in the presence of severe metabolic imbalance, while atrioventricular block was largely an independent primary event. CONCLUSIONS: Hospitalized patients with COVID-19 who die experience malignant cardiac arrhythmias more often than those surviving to discharge. However, these events represent a minority of cardiovascular deaths, and ventricular tachyarrhythmias are mainly associated with severe metabolic derangement.

Nonmelanoma skin cancers of the ear: correlation between subanatomic location and post-Mohs micrographic surgery defect size.

BACKGROUND: Nonmelanoma skin cancer (NMSC) of the ear can result in large defects with significant morbidity. OBJECTIVE: To determine whether subanatomic location of NMSCs, based on ease of visualization of the ear, correlated with post-Mohs micrographic surgery (MMS) defect size. METHODS: A retrospective chart review of 142 post-MMS ear lesions was performed and categorized according to subanatomic location: the helix, antihelix, and tragus (Location 1); retroauricular (Location 2); and conchal bowl, scapha, and triangular fossa (Location 3). RESULTS: The average defect sizes were 2.50 cm(2) (Location 1), 5.76 cm(2) (Location 2), and 4.03 cm(2) (Location 3). Tumors in Location 1 were significantly smaller than those occurring in Location 2 (P<.001) and Location 3 (P<.01), but a significant difference in size was not seen between Locations 2 and 3 (P=.16). As a control group, we randomly selected 50 NMSC cases from the nose and found the average defect size of nose NMSCs to be 1.58 cm(2). CONCLUSIONS: MMS defects of the ear are larger in nonvisible parts of the ear. As a group, MMS defects on the ear were larger than those on the nose.
