Sexual and gender minority (SGM) cancer survivors face unmet care needs in accessing cancer health information and social support despite high satisfaction with treatment. SGM patients often delay care due to concerns of discrimination in healthcare settings, though the care experiences of SGM skin cancer survivors are less known. SGM individuals, particularly sexual minority men, report higher skin cancer prevalence and related risk behaviors than heterosexual men.

Introduction: Acne impairs quality of life, often leads to permanent scars, and causes psychological distress. This review aims to update dermatologists on the Federal Drug Administration (FDA)-approved and off-label use of combined oral contraceptives (COC), clascoterone, spironolactone, and emerging hormonal therapies for acne treatment.

Methods: We reviewed current literature on hormonal acne treatments and discussed common patient concerns, barriers to care, and individualized care needs.

Purpose: Transgender and gender-diverse (TGD) people may have been disproportionately impacted by the COVID-19 pandemic, yet little is known about vaccination status in this population. This multicenter cohort study of insured adults examined the rates of COVID-19 vaccine initiation and completion in TGD persons compared to matched cisgender persons.

Methods: A cohort of TGD persons and matched cisgender persons enrolled in Kaiser Permanente health plans in Northern and Southern California between 12/1/2020 and 7/31/2021 were analyzed.

Importance: Masculinizing gender-affirming hormonal therapy is associated with the development of acne. While isotretinoin is a highly effective acne treatment, little is known about its effectiveness and safety among transgender and gender-diverse individuals receiving gender-affirming hormonal therapy.

Objective: To evaluate clinical outcomes of isotretinoin among transgender and gender-diverse individuals receiving gender-affirming hormonal therapy.

Importance: Dermatologists prescribe more oral antibiotics per clinician than clinicians in any other specialty. Despite clinical guidelines that recommend limitation of long-term oral antibiotic treatments for acne to less than 3 months, there is little evidence to guide the design and implementation of an antibiotic stewardship program in clinical practice.

Objective: To identify salient barriers and facilitators to long-term antibiotic prescriptions for acne treatment.

Article Synopsis
  • * Patient satisfaction is influenced by factors like care quality, technical performance, and accessibility, while clinician satisfaction is affected by care quality, communication, and financial issues.
  • * Evaluating satisfaction across different teledermatology models (store-and-forward, live interactive, hybrid) is crucial for ensuring high-quality care and fostering the acceptance of teledermatology as an effective option in dermatologic services.

Background: Veterans Affairs health care systems have been early adopters of asynchronous telemedicine to provide access to timely and high-quality specialty care services in primary care settings for veterans living in rural areas. Scant research has examined how to expand primary care team members' engagement in telespecialty care.

Objective: This qualitative study aimed to explore implementation process barriers and facilitators to using asynchronous telespecialty care (teledermatology and tele-eye care services).

Purpose Of Review: Transgender and gender-diverse (TGD) adolescents often face dermatologic concerns during gender-affirming care but may face limited access to dermatologists. This review aims to provide practical guidance for pediatricians on managing common dermatologic needs in TGD adolescents, including acne, hair growth promotion or removal, and post-surgical scarring within the context of gender-affirming care.

Recent Findings: Acne management should consider the impact of testosterone therapy and chest binding, with treatment options including topical retinoids, benzoyl peroxide, oral antibiotics, combined oral contraceptives, and spironolactone.

Relationships between cutaneous adverse effects (CAEs) and noncutaneous adverse effects (NCAEs) of melanoma immunotherapy may help identify patterns tied to distinct immunologic pathways. The objective of this study was to determine the associations between CAEs and NCAEs among patients with stages III-IV melanoma receiving immunotherapy and who were enrolled in a prospective cohort. Electronic medical record data were abstracted from the first immunotherapy infusion until 1 year later.

The delivery of dermatology services has undergone dramatic changes in the past century. The goals and timelines of care have evolved as have the diagnostic and therapeutic tools, resulting in the need to capture and manage information differently, both qualitatively and quantitatively. The predominant and basic office-based ambulatory care model has remained relatively unchanged.

Article Synopsis
  • Poppers, or volatile alkyl nitrites, are inhaled by men who have sex with men (MSM) for their psychoactive effects and can cause a skin condition known as "poppers Dermatitis," which can manifest as irritant contact dermatitis (ICD) or allergic contact dermatitis (ACD).
  • A study analyzing 13 articles and 18 patients found that most cases were male, with the most common diagnosis being ICD. The chemicals involved included amyl nitrite and butyl nitrite.
  • The rashes typically affect the midface area, presenting as various forms such as yellow crusting or erythema, and dermatologists should consider this condition when patients present with similar symptoms, particularly in MSM populations
