Treatment strategies for cutaneous squamous cell carcinoma in situ (cSCCIS) are many but reported cure rates are variable and few studies report 5-year follow-up data.

To evaluate the treatment of cSCCIS by curettage followed by topical imiquimod 5% cream (C&I).

We evaluated all immunocompetent patients with biopsy proven cSCCIS treated by C&I between January 2008 and December 2012.

A total of 861 patients with 1,198 cSCCIS were treated, with median follow-up of 71 months. The mean tumor diameter was 10.2 mm. LAQ824 ic50 The average duration of treatment with imiquimod 5% cream was 21 days. Kaplan-Meier estimated recurrence-free survival at 5-year follow-up was 99.71% with 95% CI (99.38%, 100.00%). A follow-up questionnaire returned by 45% of patients revealed that 94% were satisfied with their treatment. Six hundred eleven patients developed a new nonmelanoma skin cancer (NMSC) during the follow-up period, and 91% (556/611) of patients chose this combination treatment for at least one new NMSC.

The combination treatment for cSCCIS of C&I had less than 1% cumulative probability of treatment failure at 5 years. Patients tolerated the treatment well, with the majority choosing this method of treatment for at least one new NMSC.

Melanoma in situ (MIS) can have poorly defined borders and subclinical extension that makes margin control challenging. Reflectance confocal microscopy (RCM) is a promising noninvasive technique that can be used to assess subclinical spread.

To optimize surgical margins of histology-proven MIS using RCM mosaics.

Prospective review of 22 patients with histology-proven MIS who underwent RCM margin mapping prior to staged excision, between August 1, 2018, and August 13, 2020, at the Department of Dermatology, University of New Mexico, School of Medicine.

Twenty patients (91%) had tumor clearance on the first stage using a 3-mm surgical margin after confocal margin mapping.

Reflectance confocal microscopy margin mapping using the mosaic device tends to clear MIS in one stage, and the use of the handheld device may improve the accuracy for difficult anatomic areas. Current Procedural Terminology codes for RCM do not reflect the time required and complexity of the procedure. Reflectance confocal microscopy margin mapping prior to excision has the potential to decrease the number of stages needed for melanoma removal, reduce treatment time, and cost.

Management of basal cell carcinoma (BCC) varies by histopathologic subtype; however, biopsies may inadequately characterize them as nonaggressive, risking potential suboptimal treatment.

To characterize the rate of undetected aggressive BCC subtypes by size, location, and histopathology type.

Retrospective cohort study of 928 BCCs treated with Mohs Micrographic Surgery (MMS) at a tertiary academic institution from 2015 to 2017, comparing patient and tumor characteristics and histopathologic subtype on biopsy versus Mohs.

Among the 825 BCCs with known subtypes on biopsy, 68% (561/825) were classified as nonaggressive, 28% (159/561) of which were subsequently found to have aggressive subtypes on MMS. Aggressive features were more often underrepresented in biopsy samples taken from Area H compared with Area M/L (odd ratio [OR] 2.65, 95% confidence interval [CI] 1.73-4.08, p < .001) or those with nodular subtypes (OR 2.19, CI 1.08-4.45, p = .03). Of concern, these unsuspected aggressive BCCs required more Mohs stages for clearance (mean 2.37, SD 0.72, p < .001) compared with BCCs that remained nonaggressive on both biopsy and Mohs (mean 1.50, SD 0.75).

Given the high percentage of BCCs with unsuspected aggressive subtypes, higher clinical suspicion for undiagnosed high-risk BCCs should be given to nodular BCCs and to BCCs on Area H.

After uneventful anesthetic induction and surgical resection with modest blood loss, the patient developed refractory hypoxemia on emergence without significant hemodynamic changes. Despite delivery of fraction of inspired oxygen (Fio2) = 1.0, confirmed position of the double-lumen tube, and exclusion of common causes of hypoxemia, hypoxemia persisted. An emergent transesophageal echocardiogram revealed a significant intracardiac shunt due to a patent foramen ovale. Specific cardiorespiratory management to achieve a positive left-right heart pressure gradient resulted in prompt normoxemia and successful extubation.
To review the application of intersectionality to heart failure. Intersectionality refers to the complex ways in which disenfranchisement and privilege intersect to reproduce and influence health and social outcomes.

Intersectionality challenges approaches that focus on a single or small number of socio-demographic characteristics, such as sex or age. Instead, approaches should take account of the nature and effects of a full range of socio-demographic factors linked to privilege, including race and ethnicity, social class, income, age, gender identity, disability, geography, and immigration status. Although credible and well established across many fields - there is limited recognition of the effects of intersectionality in research into heart disease, including heart failure. This deficiency is important because heart failure remains a common and burdensome syndrome that requires complex pharmacological and nonpharmacological care and collaboration between health professionals, patients and caregivers during and at the end-of-life.
