Psoriasis (PsO) is a chronic inflammatory skin condition, often accompanied by psoriatic arthritis (PsA) and linked to various comorbidities and increased mortality rates. This study aimed to explore the relationship between PsO and accelerated biological aging, specifically focusing on epigenetic DNA methylation clocks. Using a matched case-control design, 20 PsO cases were selected along with age, race, and sex-matched 20 controls without PsO from the Skin Disease Biorepository at Brown Dermatology, Inc, Providence, Rhode Island. Blood samples retrieved from both groups were analyzed for DNA methylation, and epigenetic ages were calculated using DNA methylation clocks, including Horvath, Hannum, Pheno, SkinBlood, and Grim ages. Generalized estimation equations were employed to test the differences in epigenetic and chronological ages between PsO cases and controls, as well as within various subgroups in comparison to their respective controls. There were no statistically significant differences in epigenetic ages between PsO cases and controls. However, notably, PsO cases with PsA demonstrated an accelerated PhenoAge, compared to their matched controls. This study represents a pioneering investigation into the potential link between PsO and epigenetic aging, shedding light on the possibility of accelerated epigenetic aging in PsA, possibly associated with heightened inflammatory burden. These findings emphasize the systemic impact of PsA on the aging process, prompting the need for deeper exploration into autoimmune pathways, inflammation, and epigenetic modifications underlying PsO pathogenesis and aging mechanisms. Larger-scale studies with diverse populations are imperative to discern PsO subgroups experiencing accelerated biological aging and decipher the intricate interplay between PsO, inflammation, and aging pathways.

Wound repair of the pretibial and forearm regions presents a challenge during dermatologic surgery as these areas are under significant tension and exhibit increased skin fragility. Various methodologies have been proposed for the closure and repair of such wounds, however, the use of the bilayered suture technique may be simpler and more effective than other techniques such as the pinch stitch, pully stitch, slip-knot stitch, pulley set-back dermal suture, horizontal mattress suture, pully stitch, and tandem pulley stitch. Our objective was to describe a novel method for the repair of pretibial and forearm wounds following Mohs micrographic surgery utilizing bilayered closure followed by tissue adhesive application.

INTRODUCTION: With the advent of virtual interviews and the increasing accessibility of internet resources, students increasingly rely on program websites for residency application decisions. In this cross-sectional study, we evaluated the presence of diversity or inclusion information in the least diverse US specialties' residency program websites, including dermatology, orthopedic surgery, otolaryngology, plastic surgery, and urology residency programs. METHODS: Two authors independently reviewed each Accreditation Council for Graduate Medical Education-accredited non-military US residency program website and ranked the websites' diversity and inclusion information using six pre-determined criteria based on previous studies in the literature. RESULTS: This study reveals that more than half of residency programs of each specialty met zero of the diversity and inclusion information criteria. CONCLUSIONS: Residency program websites in the least diverse specialties are lacking important information for prospective applicants that may help signal programs' commitment to inclusivity and attract a diverse candidate pool.

Hidradenitis suppurativa (HS) is a painful, disfiguring, chronic inflammatory disease affecting the axillary, inframammary, and groin regions. Black Americans are disproportionately affected by HS. Structural barriers may be responsible for a lack of better prevention and management. This paper discusses possible reasons that may lead to a more severe presentation and barriers to treatment.

Tinea versicolour, used interchangeably with pityriasis versicolour (PV), is a superficial fungal infection of the stratum corneum caused by Malassezia furfur, a fungus of the normal flora of the skin. PV occurs when conditions favour proliferation of the organism's mycelial form, such as in environments with high temperatures/humidity, in immunodeficient/immunocompromised states, and during pregnancy. PV presents as numerous well- demarcated macules with a powdery scale. Prior epidemiologic studies have indicated that underrepresented groups defined by race experience a higher burden of PV as compared to White patients. However, the burden of PV in other underrepresented groups has not previously been examined, as underrepresented groups are frequently excluded from studies evaluating the impact of dermatologic disease. The new National Institute of Health All of Us Research Program (AoU) aims to build one of the world's largest and most diverse databases to promote elucidation of health disparities, particularly in communities that have been historically excluded from biomedical research.

INTRODUCTION: Alopecia areata (AA) is the most common form of immune-mediated hair loss. Studies have begun to establish the most frequent comorbid diseases of AA; however, results have been inconsistent with few prospective studies. METHODS: A total of 63,692 women in the Nurses' Health Study, 53-80 years, were prospectively followed from 2002 to 2014 to determine whether history of immune-mediated disease was associated with AA risk. Hazard ratios (HRs) and 95% confidence intervals (CIs) for AA in relation to immune-mediated conditions were computed using Cox proportional hazard models, adjusted for AA risk factors. RESULTS: 133 AA cases were identified during follow-up. Personal history of any immune-mediated disease was associated with increased AA risk (HR 1.72, 95% CI 1.24-2.37). History of systemic lupus erythematosus (HR 5.43, 95% CI 2.11-13.97), multiple sclerosis (HR 4.10, 95% CI 1.40-11.96), vitiligo (HR 3.13, 95% CI 1.08-9.10), psoriasis (HR 2.01, 95% CI 1.00-4.03), hypothyroidism (HR 1.88, 95% CI 1.30-2.71), and rheumatoid arthritis (HR 1.66, 95% CI 1.09-2.52) were associated with increased AA risk. History of inflammatory bowel disease or Graves' disease/hyperthyroidism was not significantly associated with AA risk. CONCLUSIONS: In this prospective study, personal history of immune-mediated diseases either individually or overall was associated with increased AA risk.

Few research studies evaluating the impact of dermatologic diseases in the United States (US) have adequately included underrepresented groups. All of Us (AoU) is an ongoing precision medicine-based research initiative by the National Institutes of Health (NIH) that facilitates research in populations traditionally underrepresented in biomedical research by prioritizing them for data collection. Our objective was to evaluate the burden of onychomycosis in underrepresented groups defined by the framework provided by AoU. The AoU Registered Tier dataset version 5 was used which includes data collected between May 30, 2017 and April 1, 2021. We conducted a cross-sectional analysis linking survey and electronic health record (EHR) data to estimate the prevalence of onychomycosis in underrepresented groups defined by race, ethnicity, age (≥ 75 years), disability, sexual orientation/gender identity (LGBTQIA +), income (annual household income ≤ $35 000) and education (less than a high school degree). The latest All of Us data release includes 329,038 participants. Of these, 251,597 (76%) had EHR data and 13,874 had onychomycosis (overall prevalence, 5.5%; 95% CI, 5.4-5.6). Multivariate analyses adjusted by tinea pedis, diabetes mellitus, immune compromise, nail psoriasis, and insurance status, in addition to the aforementioned variables, revealed that, compared with White participants, Black and Hispanic participants had a higher adjusted odds of onychomycosis (OR, 1.29; 95% CI, 1.23-1.36 and OR, 1.24; 95% CI, 1.17-1.31, respectively). Higher adjusted odds of onychomycosis were also observed in underrepresented groups. Our findings suggest a disproportionately high burden of onychomycosis in underrepresented groups, although further studies are needed to replicate our findings and address this disparity.

BACKGROUND: Tinea pedis is the most common form of dermatophytosis resulting in interdigital infections. All of Us (AoU) is a National Institute of Health initiative with an emphasis on patient populations traditionally underrepresented in biomedical research. OBJECTIVES: Our objective was to evaluate the burden of tinea pedis in underrepresented groups in the United States, utilising the novel AoU research program. METHODS: We analysed AoU Registered Tier dataset version 5, which includes data collected between 30 May, 2017, and 1 April, 2021. We conducted a cross-sectional analysis linking survey and electronic health record (EHR) data to estimate the prevalence of tinea pedis in underrepresented groups. RESULTS: All of Us data release includes 329,038 participants. Of these, 251,597 (76.5%) had electronic health record data and 6932 had tinea pedis (overall prevalence, 2.76%; 95% CI, 2.69-2.82). Multivariate analyses revealed that compared with White participants, Black and Hispanic participants had a higher adjusted odds of tinea pedis (OR, 1.29; 95% CI, 1.20-1.38 and OR, 1.38; 95% CI, 1.28-1.48, respectively). Higher adjusted odds of tinea pedis were observed in underrepresented groups defined by: age > =75 years (OR, 1.45; 95% CI, 1.33-1.57), LGBTQ status (OR, 1.17; 95% CI, 1.09-1.27), less than a high school education (OR, 1.22; 95% CI, 1.11-1.34), income <$35,000 (OR, 1.09; 95% CI, 1.02-1.16) and physical disability (OR, 1.56; 95% CI, 1.08-1.24). CONCLUSIONS: Our findings are consistent with overall age, and gender-specific prevalence estimates from prior epidemiologic studies, validating the scientific consistency of the new AoU database. Additionally, there may be an increased burden of tinea pedis among Black and Hispanic individuals.

Family pedigrees allow for a more thorough understanding of human genetic disorders. They are used to help establish patterns of inheritance and to identify individuals at risk of disease. Pedigree analysis can be helpful in identifying genetic disorders that demonstrate mechanisms such autosomal dominant or recessive inheritance, X-linked inheritance, and anticipation.

Inherited retinal diseases (IRDs), including retinitis pigmentosa, have devastating consequences for the visual function of affected individuals. Chief among these are a gradual loss of visual field, visual acuity, and night vision (otherwise known as nyctalopia). These changes often occur slowly, over a course of decades. Objective modalities for assessing these many aspects of visual function are crucial, not only to the monitoring of disease progression but, in recent years, also to evaluating the efficacy or lack thereof of new therapeutic interventions in the setting of clinical trials. This chapter will provide descriptions of these valuable assessment modalities, alongside discussions of their advantages and limitations in the context of serving those afflicted by IRDs.
RESUMEN
Following its implementation in the 1960s, fluorescein angiography (FA) has become a widely used and reliable tool in the diagnosis of retinal and choroidal disorders. FA is an imaging modality utilized to examine the circulation of the retina and choroid. Here, we describe the process of obtaining fundus images with sodium fluorescein dye as a contrast agent. Using this methodology, ophthalmologists may examine the retinal and choroidal vasculature to diagnose a wide scope of retinal and choroidal diseases.

Indocyanine green (ICG) angiography was first approved by the Food and Drug Administration for human use in the 1956. Prior to its use in chorioretinal angiograms, ICG was used to measure blood flow and track cardiac output. It was only in 1969 when two researchers, Kyuga Kogure and Earl Choromokos from the University of Miami, first used ICG to create more accurate angiograms. In the following years, researchers were able to hone the underlying science of this new form of angiography. As time passed and technology advanced, the application of ICG in clinical practice became widespread. Today ICG is used to diagnose and monitor the progression of retinal and choroidal diseases affecting millions of individuals across the globe. ICG utilizes the injection of indocyanine green dye into a patient's bloodstream to visualize abnormalities of the choroid and retina by evaluating choroidal circulation. ICG angiography is useful in the diagnosis and management of occult choroidal neovascularization in age-related macular degeneration and may be used in other inflammatory conditions with central serous chorioretinopathy. ICG angiography offers advanced imaging for improved monitoring and treatment of a wide variety of choroidal and retinal diseases.
