Gleison Duarte warns that oral corticosteroids initially appear to cure psoriasis but cause a dangerous rebound flare when they leave the body.

1. NETOCAST episode 1520, dated 28 October 2022, covers the World Day of Awareness about Psoriasis with a focus on medical facts and practical guidance. 2. Host José Castanhas Neto interviews Gleison Duarte, a coordinator of Brazil's National Campaign for Awareness about Psoriasis and member of the Brazilian Dermatology Society. 3. The episode's core purpose is to counter the widespread stigma of contagion and give listeners actionable information on recognition, triggers, and treatment options. 4. Duarte states that psoriasis is immune-mediated, not contagious: no bacteria, fungus, or virus is involved, and the plaques arise from abnormal immune-cell proliferation. 5. The Brazilian Dermatology Society estimates psoriasis affects approximately 5 million Brazilians, and Duarte notes the disease has been documented throughout recorded history. 6. Genetic predisposition is necessary for psoriasis to develop, but the triggering gene can remain silent in family members who have not yet encountered environmental activators such as stress, alcohol, or COVID-19 infection. 7. Plaque psoriasis, accounting for 80% of cases, classically affects elbows, knees, the scalp, and the lower back; nail psoriasis, pustular psoriasis, and palmoplantar psoriasis are other recognized forms. 8. Beyond the aesthetic impact, many patients experience significant itching preventing sleep, pain from fissured lesions that bleed on water contact, and in extensive cases, an unpleasant skin odour. 9. Duarte frames stress as a 'vicious circle': it can trigger psoriasis onset, while living with untreated psoriasis raises the risk of depression, anxiety, and suicidal ideation in patients. 10. The 2022 National Campaign slogan positions psoriasis as 'much more than plaques on the skin,' emphasising the systemic and mental-health components that are often overlooked. 11. Treatment is chosen by severity: topical preparations for mild disease, oral systemic drugs or phototherapy for moderate disease, and immunobiological drugs for severe or refractory cases. 12. Immunobiologics are proteins that block specific inflammatory molecules linked to psoriasis genes, achieving targeted suppression analogous to 'a laser beam instead of a machine gun,' often clearing skin within weeks. 13. The episode's most actionable warning — framed by Duarte as 'if you forget everything else, don't forget this' — is that oral and injectable corticosteroids must never be used for psoriasis, as apparent short-term clearing is followed by a dangerous pustular rebound. 14. Duarte confirms that generic medications for psoriasis are as reliable as branded ones, and recommends patients whose medication causes side effects return to a specialist rather than switch independently. 15. Sun exposure for seven to ten minutes daily is recommended as an anti-inflammatory measure and cannot be replaced by oral vitamin D supplements. 16. Dermatological moisturisers without fragrances — including those with urea — are advised to compensate for the skin barrier defect common in psoriasis patients, who have increased transepidermal water loss. 17. A listener from Livramento de Nossa Senhora, Bahia — identified as Manelzinho — wrote in about switching from a branded to a generic medication and experiencing headaches; Duarte used the question to reiterate the corticosteroid warning. 18. The host references her own mother's psoriasis and attributes beach holidays to disease improvement; Duarte suggests the benefit comes from both reduced stress and daily sun exposure on affected skin. 19. Brazilians with chronic health conditions who want accessible, medically credible information about skin diseases will find this episode practically useful. 20. Listeners looking for entertainment content or who are not dealing with psoriasis personally or in their family will likely not find the episode engaging.
