Background: Dermographic urticaria (DU) is characterized by strong itch and wheals induced by mechanical scratching. H(1)-receptor antagonists may reduce symptoms of DU to some extent, but other treatments being used for chronic spontaneous urticaria, such as H(2)-receptor antagonists and corticosteroids, are not usually effective for DU. Case Summary: We here report six cases of antihistamine-resistant DU treated with oral ciclosporin. Four cases suffering from severe itches that spontaneously occurred before the appearance of wheals in response to scratching were substantially improved by use of ciclosporin for 21, 16, 32, and 8 months, and one of them reached complete remission. Two cases did not obtain a benefit from the treatment, because of insufficient effects and/or side effects. Discussion: Oral ciclosporin may be of value as a potential treatment of anti-histamine-resistant DU.

A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, esophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (Segen, Dictionary of Modern Medicine, 1992)
Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.
Generalized or localized diffuse fibrous overgrowth of the gingival tissue, usually transmitted as an autosomal dominant trait, but some cases are idiopathic and others produced by drugs. The enlarged gingiva is pink, firm, and has a leather-like consistency with a minutely pebbled surface and in severe cases the teeth are almost completely covered and the enlargement projects into the oral vestibule.

A systemic non-thrombocytopenic purpura caused by HYPERSENSITIVITY VASCULITIS and deposition of IGA-containing IMMUNE COMPLEXES within the blood vessels throughout the body, including those in the kidney (KIDNEY GLOMERULUS).
