Abstract

There are multiple treatment modalities for periungual warts (PWs), although most are destructive and painful, limiting their application. Radiotherapy is a non-invasive method suitable for treating PW patients with contraindications to invasive procedures. To investigate the efficacy and safety of topical Tretinoin combined with Superficial X-ray therapy (SXRT) in treating PWs. This study included patients with 65 PWs who underwent treatment and a 3-month follow-up. Twenty four PWs were subjected to SXRT alone (group A). The remaining 41 PWs were subjected to SXRT combined with the application of the Tretinoin cream from the first day (group B). The overall clinical response rate, recurrence rates, cosmetic outcomes, and adverse events were observed during the follow-up period. The complete clearance rate (75% vs. 92.7% in groups A and B, respectively) and healing times (19.9 vs. 16.0 days in groups A and B, respectively) between the two groups were significantly different (p < 0.046 and 0.04), indicating the combination treatment is more effective. Notably, there was no damaging or permanent deformation on the nail, and the other adverse effects were mild and bearable. Topical Tretinoin combined with SXRT therapy is an effective strategy for treating PWs, with minor side effects. It is painless and with excellent cosmetic outcomes.

Skin barrier function in patients under radiation therapy due to the head and neck cancers - Preliminary study

Jakub Pazdrowski, Adriana Polaſska, Joanna Kaźmierska … (2019)

To present the possibility of non-invasive monitoring of the skin after radiotherapy in regards of epidermal barrier function. Radiodermatitis constitutes 95% of all side effects in patients after radiotherapy. The proper assessment of the severity of radiodermatitis can be determined using semi-quantitative clinical scores [Common Terminology Criteria for Adverse Events v 4.0 (CTCAE)].The most accepted way to analyze the epidermal barrier function is to determine Transepidermal Water Loss (TEWL). In prospective study, we included 16 patients diagnosed with head and neck cancer treated with radiotherapy or concomitant chemoradiation in whom we performed non-invasive assessments of the skin barrier function, including TEWL measurement. The final analysis included 6 patients (4 treated with adjuvant radiotherapy, 2 with radical chemoradiation). Clinical assessment of irradiated skin was based on target lesion score (TLS) and CTCAE v 4.0 The mean TLS score in the middle of irradiation was 1.6 points, after last irradiation it was 2.3 points; 3 months later the mean TLS score was: 0. CTCAE v 4.0 criteria: 2 patients had grade 0, 3 patients - grade 1; 1 patient - grade 2. There were statistically significant differences in TEWL related to irradiated skin in the following time intervals: before vs. in the middle; before vs. day after; in the middle vs. day after; in the middle vs. 3 months after; day after vs. 3 months after. The study showed that radiotherapy causes skin barrier dysfunction in all patients independently of clinical radiodermatitis. The biophysical features of this dysfunction can precede clinical symptoms and they can be assessed by non-invasive and objective methods.

Topical vitamin A treatment of recalcitrant common warts

Anca Gaston, Robert Garry (2012)

Background Common warts (verruca vulgaris) are benign epithelial proliferations associated with human papillomavirus (HPV) infection. Salicylic acid and cryotherapy are the most frequent treatments for common warts, but can be painful and cause scarring, and have high failure and recrudescence rates. Topical vitamin A has been shown to be a successful treatment of common warts in prior informal studies. Case The subject is a healthy, physically-active 30 old female with a 9 year history of common warts on the back of the right hand. The warts resisted treatment with salicylic acid, apple cider vinegar and an over-the-counter blend of essential oils marketed for the treatment of warts. Daily topical application of natural vitamin A derived from fish liver oil (25,000 IU) led to replacement of all the warts with normal skin. Most of the smaller warts had been replaced by 70 days. A large wart on the middle knuckle required 6 months of vitamin A treatment to resolve completely. Conclusion Retinoids should be further investigated in controlled studies to determine their effectiveness in treating common warts and the broad range of other benign and cancerous lesions induced by HPVs.

Successful treatment of periungual warts with topical cidofovir.

Laura Padilla España, Javier Del Boz-González, Teresa Fernández-Morano … (2024)

Periungual warts represent a treatment challenge because of its high recurrence rate and recalcitrance. These are benign lesions produced by the human papilloma virus (HPV) that often do not respond to habitual treatment. Cidofovir is a potent antiviral drug that acts inactivating viral DNA polymerase. Topical cidofovir for the treatment of HPV-related cutaneous and mucous lesions is becoming increasingly common. Our aim was to assess the efficacy and safety of cidofovir cream for the treatment of viral periungual warts. We undertook a retrospective observational study of patients with periungual warts who received treatment with topical cidofovir between January 2010 and December 2013 at the Dermatology Service of the Hospital Costa del Sol, Marbella, Spain. Data were recorded about the rate of treatment response, the adverse effects and recurrences, as well as the characteristics of the patient cohort. We identified 41 patients who had received some previous treatment. The concentration of cidofovir was 3% in all cases, usually applied twice a day (in 37 of the 41 cases). A greater or lesser response was noted in 35 cases. There were six recurrences in the follow-up period. Topical cidofovir seems to be a useful alternative for the therapeutic management of recalcitrant periungual common warts that fail to respond to usual treatment. Our experience with the use of this antiviral agent has been satisfactory, although in our opinion, it should be reserved for specific cases as its economical cost represents an important limitation.
