☆ I 2022 Stiftung Warentest-resultaterne fra Tyskland var forbrugernes tilfredshed med ModelDerm kun lidt lavere end med betalte telemedicinske konsultationer.

En 14-årig dreng kom ind med tykke, gulbrune skæl i hovedbunden, hovedsageligt foran og på toppen. De berørte områder var røde og skællende med hårtab, men ingen ar. Test for svamp var negative.
A 14-year-old male patient presented with focal masses of thick, adherent, plate like, yellow-brown scales, attached to the hair shafts, predominantly affecting the fronto-parietal area and vertex of the scalp. The underlying scalp had thick, erythematous plaques with fine, non greasy, silvery-white scaling with noncicatricial alopecia. Potassium hydroxide examination of scales and hair and culture for fungus was negative.

Pityriasis amiantacea kan komme fra enhver hudsygdom, der hovedsageligt påvirker hovedbunden, som seborrheic dermatitis. Men vi er ikke helt sikre på, hvordan det starter. Vores mål er at studere mønstrene blandt patienter med pityriasis amiantacea for at forstå, hvordan behandlinger fungerer bedre. Vi tjekkede 63 børn ud med seborrheic dermatitis og fandt syv tilfælde af pityriasis amiantacea , hovedsagelig hos piger. Vi fulgte dem i cirka 20. 4 måneder i gennemsnit og fandt ud af, at de var omkring 5. 9 år gamle. Blandt dem var fem piger med en gennemsnitsalder på 9 år. Alle patienter blev behandlet med succes med emnet ketoconazol.
The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole.

Pityriasis amiantacea påvirker hovedbunden som skinnende tykke skæl. Skællene omgiver og binder hårtotter ned. Tilstanden kan være lokaliseret eller dække over hele hovedbunden. Midlertidig alopeci og ardannelse alopeci kan forekomme på grund af gentagen fjernelse af hår fastgjort til skalaen. Det er en sjælden sygdom.
○ Behandling ― OTC-lægemidler
*Keratolytiske midler indeholdende urinstof kan hjælpe med at behandle den tykke skæl.

#Fluocinolone shampoo
#Pyrithione zinc shampoo
