Intralesional combined digoxin and furosemide versus intralesional 5-flurouracil for the treatment of recalcitrant plantar warts: a prospective, randomized study.

There are many therapeutic modalities for plantar warts, however treating it remains challenging. Intralesional injection of 5-fluorouarcil and combined digoxin and furosemide were observed to be effective and safe, however no comparison study between them was done. Our study was conducted to evaluate the efficacy of both therapies in the treatment of plantar warts. 90 adult patients with multiple recalcitrant plantar warts were included in our study. They were randomly allocated to one of three groups; combined digoxin and furosemide, 5-fluorouarcil, or normal saline group. Fortnightly injections were done into all studied warts till complete clearance or up to 5 sessions. Warts were evaluated clinically and dermoscopically. Clinical response was reported in 24 patients (80%) of the combined digoxin and furosemide group with 40% complete response and in 24 patients (80%) of the 5-fluorouarcil group with 33.3% complete response. No statistically significant difference was observed between the two groups concerning efficacy and safety. Intralesional injection of 5-fluorouarcil and combined digoxin and furosemide are nearly equivalent in efficacy and safety for plantar wart treatment. Dermoscopy helps to take the truthful judgment about complete clearance of warts.

Morphometric study of lymphangiogenesis in different lesions of psoriasis vulgaris with correlation to disease activity.

BACKGROUND AND OBJECTIVES: In the last decades, attention to the role of lymphangiogenesis in psoriasis has been paid. Our study was conducted to evaluate podoplanin-stained lymphatic vessels and the level of lymphangiogenesis in papular psoriatic lesions and psoriatic plaques and ascertain if podoplanin provides any additional prognostic information. MATERIALS AND METHODS: Number of lymphatic vessels and total lymphatic vessel area were morphometrically analyzed in podoplanin-stained sections, using anti-D2-40, together with the immunohistochemical study of epidermal Ki-67 in psoriasis vulgaris (n = 20) (papules = 7 and plaques = 13) and control skin specimens (n = 20). RESULTS: The number of lymphatic vessels and total lymphatic vessel area were higher in psoriasis cases compared with normal skin (p = 0.01, p = 0.01 respectively). In psoriatic plaques, the number of lymphatic vessels, total lymphatic vessel area, and epidermal Ki-67 immunoreactivity were higher than in papular lesions (p = 0.002, p = 0.008, and p = 0.01, respectively). CONCLUSIONS: Psoriasis vulgaris is found to be a lymphangiogenesis-dependent disease, and the lymphatic vascular network is in remodeling and expanding process. Podoplanin may be implicated in the pathogenesis of psoriasis and could be used as a prognostic biomarker for disease severity and progression.
