Dermatologic

15 cases on atopic dermatitis management (JAK inhibitor selection with cardiovascular risk, reactive versus scheduled maintenance steroid therapy, infant facial eczema, refractory pediatric disease, dupilumab dual-indication and add-on biologic decisions), allergic contact dermatitis, chronic spontaneous urticaria (antihistamine updosing, omalizumab escalation, autoimmune-marker-guided therapy), cold urticaria and anaphylaxis risk, hereditary and ACE-inhibitor angioedema, and idiopathic angioedema without hives — choose a case below to open its full multi-voice debate.

Chronic Urticaria After Six Months of Omalizumab: What Actually Comes Next

Six months of standard-dose omalizumab hasn't cleared her hives, and the choice between dose escalation, cyclosporine, and a newly approved oral BTK inhibitor is genuinely unsettled.

A Positive Autoimmune Marker in Chronic Urticaria: Does It Change What Happens Next

A positive autologous serum skin test in a nurse's chronic hives raises a real question: does the autoimmune label change the treatment ladder or just describe it.

Cold Urticaria in an Open-Water Swimmer: Inducing Tolerance or Just Staying Out of the Water

Recurring Angioedema Without Hives, and Without an Explanation on Any Lab Result

A mother of teenagers has recurring angioedema with normal complement and no hives, and the safer diagnostic-therapeutic trial isn't the one that matches her actual symptom pattern.

Case 0012
