Lasers, Scabies & Dupixent Dilemmas

Acne management evolves with the 1726 nm laser, which demonstrates efficacy in moderate-to-severe cases over one year, though high costs limit its utility compared to systemic options like isotretinoin. Regarding pemphigus, maintenance therapy with mycophenolate mofetil following rituximab fails to improve remission rates and may increase infection risks by lowering CD8 T-cell counts. Dupilumab shows no association with increased cutaneous T-cell lymphoma risk in atopic dermatitis patients, potentially reducing overall hematologic malignancy rates. Spironolactone use in women over 45 presents a low, often asymptomatic risk of hyperkalemia, suggesting that intensive monitoring is unnecessary for healthy patients. Finally, Hurley Stage 1 hidradenitis suppurativa progresses in nearly 38% of cases, with smoking and specific lesion types serving as key predictors, while early intervention through punch drainage may mitigate long-term severity.
