The effect of mouse L-cell interferon on bovine papillomavirus type 1 (BPV-1) transformation of murine cells was examined. Mouse interferon reduced the level of BPV-1-induced transformation of mouse C127 cells by 95%. Long-term treatment of established BPV-1-transformed mouse cell clones with mouse L-cell interferon led to a decrease in the average number(More)
BACKGROUND An elderly woman with B-cell lymphoma confined to the skin of the lower extremity was treated with combination chemotherapy and radiation therapy. She relapsed with new skin lesions outside the original radiation port that responded to additional radiation therapy and remains in remission 12 months after her last treatment. OBJECTIVE This(More)
In ten patients with gyrate atrophy (GA) and hyperornithinemia, the head hair was fine, straight, and sparse. On microscopic examination, both scalp and pubic hair contained intermittent dark cores within the medullary zone, which was not a deposit, but appeared to be due to the unusual refractive properties of loosely formed macrofilaments amidst wide(More)
Birt-Hogg-Dubé syndrome (BHDS) is an uncommon autosomal dominant genodermatosis characterized by a triad of skin tumors--fibrofolliculomas, trichodiscomas, and acrochordons--together with an increased risk of renal tumors and spontaneous pneumothoraces. This report describes multiple facial angiofibromas as the predominant initial manifestation of BHDS. The(More)
BACKGROUND Hyperthermia therapy was described previously to be effective for treating warts using a hot water technique as well as an ultrasound hyperthermia technique. Recently, two other papers described controlled localized heat therapy for cutaneous warts. A new heat-generated application system and method has been developed for treating warts using a(More)
Papillomaviruses are a family of nonenveloped DNA viruses that infect the skin or mucosa of their vertebrate hosts. The viral life cycle is closely tied to the differentiation of infected keratinocytes. Papillomavirus virions are released into the environment through a process known as desquamation, in which keratinocytes lose structural integrity prior to(More)
The susceptibility of human papillomavirus infection to polyclonal human leukocyte interferon (IFN-alpha) has been evaluated in patients with epidermodysplasia verruciformis (EV), a disease with extensive chronic papillomavirus-induced warts. In a double-blind, placebo-controlled study with intralesional IFN-alpha, four of five IFN-alpha-treated warts(More)
