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.

Safety and efficacy of intralesional polidocanol sclerotherapy in the treatment of plantar warts: a pilot study.

Plantar warts are common skin lesions that continue to represent a therapeutic challenge. They are still resistant to therapy and are highly recurrent, despite the diverse number of treatments available. Therapies targeting vasculature, such as pulsed dye laser, have been used successfully in the treatment of plantar warts. Polidocanol, a detergent sclerosant approved for the sclerotherapy of incompetent and dilated saphenous veins, has also been used as an off-label therapy for a wide range of skin conditions with vascular components such as hemangiomas and pyogenic granuloma. The current, open-label, prospective, pilot study aimed to evaluate the safety and efficacy of the intralesional polidocanol 3% in the treatment of plantar warts. Twenty patients (11 females and 9 males), with plantar warts, aged 12-50 years received biweekly sessions of intralesional polidocanol 3% until complete clearance or for a maximum of 6 sessions. Response to treatment was graded as complete (100% clearance), partial (50-99%), and no response (< 50%). At the end of the study, 12 (60%) patients achieved complete clearance of their warts after 1-5 sessions, 5 (25%) patients had only partial response, and 3 (15%) patients did not achieve any clearance of their warts. The procedure was largely tolerable by patients. Pain at the injection site and bruises were reported by 9 (45%) and 2 (10%) patients, respectively. Both side effects resolved spontaneously and completely within a few days. The findings of the current study suggest that intralesional injection of 3% polidocanol in biweekly sessions may be a safe, effective, and tolerable method for the treatment of plantar warts.

Clinical implementation of a multiplex PCR detection method for HPV causing plantar warts and genotype distribution in different geographical areas of Spain.

Human papillomavirus is the ethological agent of various tumors, including plantar warts as one of the most frequent clinical presentations. Diagnosis of these warts continues to be mainly clinical, and a significant incidence of misdiagnosis leads to inadequate treatment. The aim of this study is to implement and validate a multiplex PCR detection method in the clinical setting to detect HPV in samples and to study genotype distribution in Spain to improve future molecular diagnostics. Viral DNA was extracted from 128 samples of clinically suspected plantar warts from various locations in Spain. A multiplex PCR was run alongside internal controls, and amplicons were processed for sequencing and HPV genotyping. The method was validated by assessing both inter- and intra-run repeatability. The PCR detection method returned 81.2 % (n = 104) positive results in the samples tested. Inter- and intra-run repeatability tests showed excellent intra-run agreement (κ = 1.00, p < 0.001) and good inter-run agreement (κ = 0.737, p < 0.001). The most frequent HPV type was HPV1, followed by HPV27, showing a statistical difference between the distribution of HPV genotypes in different areas of Spain. Clinical implementation of a DNA PCR detection method for plantar warts can avoid 18.8 % of unnecessary treatments in doubtful cases, and the method is reliable and validated for the purpose. HPV types show an asymmetric geographical distribution that should be considered for diagnosis and treatment.

Topical antimitotic treatments for plantar warts are more beneficial: A Bayesian network meta-analysis of randomized controlled trials.

BACKGROUND: Plantar warts are common infectious cutaneous growths causing severe physiological and psychological discomforts in patients and heaving global financial burdens. However, paucity of clear-cut guidelines for plantar warts, selecting appropriate treatments for plantar warts remains challenging. The objective of the study is to evaluate the efficacy and safety of common treatments for plantar warts. METHODS: PubMed, EMbase, and The Cochrane Library were searched from inception to March 1, 2023 for randomized controlled trials (RCTs) of plantar warts. The primary outcome (complete response) and secondary outcome (recurrence and pain) were extracted and combined using Bayesian network meta-analysis (NMA) with random-effect and fixed-effect models. RESULTS: Totally, 33 RCTs were included in the systematic review and quantitative NMA. In NMA of complete response, topical application of 1% cantharidin, 20% podophylotoxin, 30% salicylic acid (CPS), microneedles plus bleomycin (MNB), and intralesional bleomycin injection (INB) were the only three treatments significantly superior to no treatment (NT) and CPS was of the highest possibility to be the top-ranked treatment (SUCRA = 0.9363). However, traditional warts treatments, salicylic acid (SA) and cryotherapy were not superior to NT. CONCLUSIONS: The NMA has produced evidence for using CPS, MNB, and INB, which are all topical antimitotic treatments, to improve the management of plantar warts. The classic treatment modalities for plantar warts, including SA and cryotherapy, may play a less important role in the clinical practice of plantar warts.

Superficial radiotherapy (SRT-100) for refractory plantar warts: An alternative noninvasive treatment strategy.

BACKGROUND: Verrucas that occur on the soles of the feet are called plantar warts, most of which can recur repeatedly and are difficult to eradicate. Hypertrophic and refractory plantar warts are often accompanied by pain and discomfort, which cause many inconveniences in patients' daily lives. AIM: This study aimed to analyze the therapeutic effect of superficial radiotherapy (SRT-100) on refractory plantar warts and further create favorable conditions for the subsequent treatment of this disease with a high recurrence rate. METHODS: A retrospective analysis was conducted for refractory plantar warts treated with superficial radiotherapy in our outpatient department from January to June 2023. RESULTS: A total of 30 patients were included in our study (median age, 33 years). The female-to-male ratio was 1:3.29. Two to six months after radiotherapy, all of the warts subsided in 23 (76.67%) patients, most of the warts subsided in 4 (13.33%) patients, 3 (10%) patients did not respond to treatment, and 7 (23.33%) patients had recurrent or new warts after their warts subsided. CONCLUSIONS: Most patients with refractory plantar warts improved after superficial radiotherapy. Our study presented that men are more susceptible to plantar warts than women, and young and middle-aged people are the main population affected by the disease. Superficial radiotherapy is an effective treatment for refractory plantar warts, which can quickly remove the warts in a short period. It is safe and noninvasive, with minimal adverse reactions. Some patients relapse after the lesion is clear, and superficial radiotherapy can create favorable conditions for the subsequent treatment of viral warts in clinical practice.

Painless and non-invasive treatment of plantar warts utilizing traditional Chinese medicine soaking: A case report.

BACKGROUND: Warts result from an infection with the human papilloma virus (HPV). Plantar warts, also known as Verruca plantaris, can be notably painful for the patient and possess contagious qualities, thus necessitating assertive treatment. Despite several available approaches for addressing plantar warts, efficacy remains elusive. CASE PRESENTATION: One 22-year-old firefighter suffered from numerous plantar warts. After 26 days of traditional Chinese medicine soaking, the rashes completely disappeared. The treatment was without complications or discomfort, and a three-month follow-up showed no recurrence. CONCLUSION: Our case investigation highlighted the efficacy of herbal soaking as a safe, painless, and non-invasive therapeutic option, positioning it as a potential avenue for managing multiple plantar warts.

Cryotherapy versus topical nitric-zinc complex solution for the treatment of plantar warts: A randomized controlled trial.

Cryotherapy is commonly regarded as the primary treatment method for plantar warts. A new medical device called nitric-zinc complex solution (NZCS) has also emerged as a potential alternative for wart treatment. The main aim of this study was to analyze and compare the effectiveness of cryotherapy using liquid nitrogen and NZCS in treating plantar warts. We conducted a randomized and controlled clinical trial involving patients with plantar warts. A total of 62 patients were enrolled in the study and monitored for 12 weeks or until their warts were completely resolved. The patients received either cryotherapy or NZCS, with a maximum of six treatment applications. The cure rate was 65.5% in the group treated with cryotherapy and 56.6% in the group treated with NZCS. The average number of treatment applications required for curing warts was significantly lower in the cured group (3.28 ± 1.63) than in the group with unresolved warts (5.5 ± 1.27) (p < 0.01). Moreover, the average number of applications was lower in the cryotherapy group (3.6 ± 1.8) than in the NZCS group (4.8 ± 1.8) (p < 0.01). Based on the findings, NZCS could be considered a favorable first-line treatment option for plantar warts.

Successful Treatment of Multiple Plantar and Periungual Warts by Local Hyperthermia Treatment: A Case Report.

Local hyperthermia treatment, a common immunoadjuvant therapy, has been used in treating various human papillomavirus (HPV) infections. For multiple warts, it can clear off all warts of the body through targeted irradiation on one wart. We reported a case of a 22-year-old patient with multiple plantar warts combined with periungual warts, in which previous treatments were ineffective. Therefore, we utilized local hyperthermia treatment at 44°C using the largest fused-wart plaque on the right plantar as the treatment target for 30-minute irradiation each time. The hyperthermia induction therapy was performed on day 1, 2, 3, 12 and 13, followed by weekly maintenance therapy for 6 times. After 2 months of treatment, both irradiated and non-irradiated lesions disappeared, and no recurrence occurred during the follow-up period. This case indicates that local hyperthermia treatment may be a safe and effective approach for patients with multiple, recalcitrant, and site-specific viral warts due to the ineffectiveness of conventional treatment.

Clinical observation and study of local hyperthermia for treating plantar warts: A pilot study with 38 patients.

Warts are benign lesions caused by infection of the keratinocytes by the human papillomavirus (HPV). There is still no consensus on the standard treatment for plantar warts, and the various treatments (both destructive and non-destructive) have variable efficacy with a long list of shortcomings, such as higher recurrence, pain, and scarring. Local hyperthermia was considered a safe, effective, and promising therapy in the treatment of plantar warts. After getting approval from the hospital's ethics committee, the present study was designed to assess the clinical efficacy of local hyperthermia in the treatment of plantar warts. A total of 38 patients were enrolled in the study, and all patients received a standard regimen in a 5-week schedule, with local 45°C treatment for 30 mins on days 1, 2, 3, 14, 15, 22, 29, and 36. Of the 38 patients, complete resolution of the warts was observed in 13 (34.2%), 8 (21.1%) achieved partial remission, and 17 (44.7%) revealed poor response to the treatment. Patients were followed up for at least 3 months, and there was no recurrence of lesions in the 13 clinically cured patients at the last follow-up. The findings in the current study demonstrate that local hyperthermia is a safe, effective, and promising therapy for the treatment of plantar warts.

Treatment efficacy of 0.9% saline and mepivacaine infiltration with Dermojet® in eliminating plantar warts.

BACKGROUND: Plantar warts are benign, epidermal neoformations, viral, and easily transmitted. Although 30% of these warts disappear spontaneously, the American Association of Dermatology recommends treatment if they cause pain or bleeding. OBJECTIVES: The aim of this study was to determine the efficacy of Dermojet® infiltration using a solution composed of equal parts of 0.9% saline and 2% mepivacaine in the treatment of plantar warts, and to identify the type of necrosis achieved at 7-10 days after the infiltration (M1 sample) and at 15-17 days (M2 sample). METHOD: In this analytical prospective observational study, 102 histories were reviewed by the same researcher. The patients were treated with this technique at four private podiatry clinics. RESULTS: A total of 61.8% of the patients were male. The patients' mean age was 26.6 ± 14.10 years. A total percentage of 78.4% of the patients achieved complete elimination of the lesion by the second evaluation and after a single infiltration. Bivariate analysis revealed a significant inverse relationship between treatment efficacy and a history of previous disease (p < 0.001) and the period of evolution of the lesion (p < 0.001; 95% CI [0.78-7.91]). Multivariate linear regression analysis revealed an association with the number of evaluation sessions (p < 0.001) and with previous illnesses (p = 0.014). A total percentage of 82.35% presented partial necrosis in the M1 sample and 76.92% had complete necrosis in the M2 sample. CONCLUSIONS: In 78.4% of the patients considered, the plantar warts treated disappeared after a single infiltration. The variables associated with treatment efficacy were the number of follow-up visits and the existence of associated diseases.

Evolución del uso en los tratamientos de las verrugas plantares / Evolution of use in the treatments of plantar warts

Objetivo: Las verrugas plantares son lesiones cutáneas causadas por el virus del papiloma humano, teniendo una prevalencia en torno al 12 % en la población general. Sus tratamientos han evolucionado a lo largo de los años, por lo cual el objetivo principal del estudio fue conocer cómo ha evolucionado el uso de los distintos tratamientos físicos y químicos para verrugas plantares en España. Material y métodos: Se realizó un estudio longitudinal mediante una encuesta en dos periodos de tiempo diferentes, a través de un formulario de Google-Forms con 17 preguntas, con el fin de recopilar datos de podólogos en activo que tuvieran experiencia clínica en el tratamiento de verrugas plantares y que trabajasen en España. Se obtuvo un total de 889 respuestas procedentes de los 17 colegios de podólogos de España en ambos periodos. Resultados: Los resultados indicaron un aumento en el uso del láser (6.1 %), pasando a ser tratamiento de primera elección en el segundo periodo, y un aumento en el uso de cantaridina (8.0 %). Además, se mostró una disminución en el uso de crioterapia (14.5 %), ácido monocloroacético/tricloroacético (13.0 %) y ácido nítrico (2.3 %), aunque este último se mantiene como tratamiento de primera elección en ambos periodos. Conclusiones: La aparición de nuevos tratamientos menos invasivos y menos dolorosos, como el láser, provoca que otros tratamientos se vean desplazados, entre los que se encuentran algunos ácidos.(AU)

Aims: Plantar warts are skin lesions caused by the human papilloma virus, with a prevalence of around 12 % in the general population. Its treatment has evolved over the years, so the main objective of the study is to find out how the use of different physical and chemical treatments for plantar warts in Spain has evolved through a longitudinal study. Material and methods: A survey was carried out through a Google-Forms form with 17 questions to collect data from active podiatrist clinicians, who had clinical experience in the treatment of plantar warts and who work in Spain. Results: A total of 889 responses were obtained from the 17 podiatry associations in Spain in both periods. The results indicated an increase in the use of the laser (6.1 %), becoming the treatment of first choice in the second period, and an increase in the use of cantharidin (8 %). In addition, a decrease in the use of cryotherapy (14.5 %), monochloroacetic/trichloroacetic acid (13 %) and nitric acid (2.3 %) is shown, although the latter remains as a first-choice treatment in both periods. Conclusions: The use of the different treatments against plantar warts has been modified over a period of 7 years, increasing in physical treatments such as laser and decreasing chemical treatments such as cryotherapy or monochloroacetic/trichloroacetic acid. The appearance of new treatments, less invasive and less painful, causes other treatments to be displaced.(AU)

The combination treatment of ozone water, superficial shaving, and photodynamic therapy in recalcitrant plantar warts: A successful case.

In this work, we report the treatment of a patient with recalcitrant plantar warts with aminolevulinate photodynamic therapy (ALA-PDT), pretreatment with ozone water, and superficial shaving. Following a single treatment session, the lesions completely disappeared after three weeks and did not reappear during the two-year follow-up. Photodynamic therapy has been reported to be successful for plantar warts with a low recurrence rate, while ozone water is an emerging treatment for infectious skin diseases, which can modulate immunity without obvious side effects. Pretreatment with ozone water and superficial shaving before PDT is a potential new strategy for treating recalcitrant and large plantar warts.

Spreading Allergic Contact Dermatitis to Tea Tree Oil in an Over-the-Counter Product Applied on a Wart.

Tea tree oil is an essential oil obtained by distillation from the leaves and terminal branchlets of Melaleuca alternifolia and is now present in numerous products for body care and self-medication. We report a case of allergic contact dermatitis to tea tree oil in a young man who was applying a lotion containing tea tree oil on a wart localized on the plantar aspect of the right big toe, which had previously been treated with cryotherapy. He developed a severe eczematous eruption on the right foot and the right leg, with subsequent id reactions affecting the right thigh, the contralateral lower limb, the trunk and the upper limbs. The lotion was discontinued, and the dermatitis resolved after topical corticosteroid therapy. Patch testing with the aforementioned lotion 10% pet. and oxidized tea tree oil 5% pet. identified tea tree oil as the culprit agent of the dermatitis. This case report confirms that products made of natural ingredients, often perceived to be harmless, can cause allergic reactions.

Verrucae pedis in children with juvenile idiopathic arthritis and other paediatric rheumatic diseases: a cross-sectional study.

BACKGROUND: Verrucae pedis (verrucae / VPs) are a common viral infection of the skin seen in children. There are limited studies of the prevalence, duration and impact of verrucae pedis in children who are immunosuppressed. The studies available suggest that, in these children, the warts are more widespread and are more long-standing. The primary aim of this study was to determine the prevalence of verrucae pedis in children attending rheumatology clinics who may have some degree of immunosuppression due to their prescribed medication and compare this to the reported prevalence in the healthy population. METHOD: Children attending out-patient rheumatology appointments were recruited. The young people were aged between four and 17 years old. A visual inspection of both feet was used to identify potential verrucae. Diagnosis of a verruca pedis was confirmed on observation of the typical clinical features. The location, duration of presence, previous treatments, presence of verrucae in other family members and psychological impact was recorded. RESULTS: A total of 71 children were included. Of the group, 55 children had no verrucae present, 16 children had one or more verrucae. The prevalence of verrucae was 22.5%. Medication impacting on the immune system was prescribed in 80% of the group. There appeared to be no greater chance of having verrucae if taking immunosuppressive medication than compared to having no medication (OR = 1.1, 95%CI 0.26 to 4.48, p = 0.46). Children with verrucae tended to be between 9 and 12 years old. In total, 37.5% of the young people with verrucae had lesions reportedly present for 24 months or more. Two-thirds of the participants were not concerned about verrucae being present and most participants with a verruca were not aware of what a verruca was, but despite this the majority of participants (81%) had sought treatment for the verrucae. CONCLUSION: Children with Juvenile Idiopathic Arthritis and other rheumatic conditions have no greater prevalence of verrucae compared to the general population. The verrucae present were of a similar clinical type and did not seem to be more widespread or have atypical features, which has been reported in other immunocompromised populations. The percentage of lesions remaining beyond 24 months was found to be slightly greater than has been reported in other healthy populations. The children in this study seemed to be less emotionally concerned about their verrucae, despite this most families had sought treatment for the verrucae.

Efficacy of cryotherapy for plantar warts: A systematic review and meta-analysis.

Recent systematic reviews of plantar warts continue to consider cryotherapy as one of the treatments of choice, but this method appears to have lower cure rates than alternative treatments. A systematic review using meta-analyses of the efficacy of cryotherapy in plantar warts treatment was performed. Systematic electronic searches were conducted. The primary endpoint was complete clearance of plantar warts. Risk-of-bias assessment was based on Cochrane Handbook recommendations. Meta-analyses used Review Manager v5.4.1 software. Cryotherapy appears to have lower cure rates than other treatments (odds ratio [OR] 0.31, 95% confidence interval [CI] 0.12-0.78) with substantial heterogeneity (I2  = 80%). A second subgroup analysis had low heterogeneity (I2  = 28.2%). Subgroup analysis showed that plantar wart cure rates were significantly lower with cryotherapy compared to the physical treatment group (OR 0.05, 95% CI 0.01-0.49) with substantial heterogeneity (I2  = 79%), and antiviral, chemotherapy, and retinoid group (OR 0.30, 95% CI 0.14-0.66) without heterogeneity (I2  = 0%). Intralesional versus spray-on cryotherapy appears to be more effective (OR 0.21, 95% CI 0.09-0.48). No difference in efficacy between two rounds of 10-s and four rounds of 5-s freeze-thaw cycles in cryotherapy was found. Evidence of the superiority of antivirals and chemotherapy over cryotherapy in the treatment of plantar warts was found. However, no evidence supports the superiority or inferiority of cryotherapy compared to other treatments.

Assessment of Visual Diagnosis by Podiatrists for HPV and Onychomycosis: The Need for Complementary Tests.

Onychomycosis and human papillomavirus (HPV) plantar warts are common in clinical practice. Clinical diagnosis is based on searching for pathognomonic signs and symptoms. However, due to misdiagnosis, podiatrists may unnecessarily prescribe antifungal treatments or burn lesions with chemical agents. The objective of this study was to assess podiatrists' visual diagnosis of these infections and their willingness to use complementary tests. A 12-item questionnaire was developed to assess visual diagnostic ability. The diagnoses of all lesions were verified before the questionnaire was sent out. The respondents were 415 podiatrists with a range of years of experience. While 86.3% of podiatrists considered complementary tests for onychomycosis necessary, only 21.4% used them regularly. As many as 60.2% would leave a distal subungual onychomycosis untreated based on visual diagnosis. In the case of HPV, only 14.5% of respondents considered complementary tests necessary, although 76.6% would treat a non-HPV lesion with regular chemical agents. Years of experience did not affect the percentage of misdiagnoses. Complementary tests are needed in clinical practice to avoid unnecessary treatments. Podiatrists easily identify clear signs and symptoms but have difficulty making differential diagnoses. Research should focus on ensuring complementary tests are available to health professionals.

Verrugas plantares recalcitrantes tratadas exitosamente con sólo una sesión de Láser PDL. A propósito de 3 casos / Recalcitrant plantar warts successfully treated with one PDL session. About 3 cases

Resumen Las verrugas plantares son una patología común en la población. Estas lesiones son a menudo dolorosas y recidivantes. Entre los tratamientos más utilizados están las terapias tópicas destructivas y menos frecuentemente el tratamiento quirúrgico. Sin embargo, con frecuencia recurren, por lo que representan un desafío para el dermatólogo. Presentamos 3 casos de pacientes varones adultos con verrugas plantares recalcitrantes que fueron tratadas exitosamente con una sola sesión de láser PDL, sin recidiva luego de 8 a 12 meses de seguimiento.

Abstract Plantar warts are a common pathology in the population. These lesions are often painful and recurring. Among the most used treatments are topical destructive therapies, and less frequently, surgical treatment. However, they frequently recur, so they represent a challenge for the dermatologist. We present 3 adult males with a recalcitrant plantar wart that were successfully treated with a single PDL laser session, without relapse after 8-12 months of follow-up.

Efficacy of the Treatment of Plantar Warts Using 1064 nm Laser and Cooling.

Cutaneous plantar warts may be treated using several optional methods, with the use of laser surgery having increased in the last few years. This work examined the efficacy of laser treatment combined with simple cooling to reduce pain. The cure rate was approximately 84%. There were no significant differences in the efficacy of treatment for different viral genotypes. The laser parameters were 500 msec pulses, 30 W of power, and a fluence of 212 J/cm2 delivered in up to four sessions. Successful treatment was achieved after an average of 3.6 sessions.

A case of resistant multiple plantar warts cured with combined autologous platelet-rich plasma injection and topical salicylic acid 30.

BACKGROUND: Plantar warts are common benign cutaneous lesions affecting the plantar aspects of the feet; they are caused by infection of the keratinocytes by the human papillomavirus (HPV). The effective treatment of plantar warts is still a therapeutic challenge. AIM: This study aimed to assess the possible clinical efficacy and safety of the combined intralesional autologous platelet-rich plasma (PRP) injection with local application of salicylic acid 30% solution in the treatment of multiple resistant plantar warts. METHOD: In the present case, a 54-year-old immunocompetent male patient presented with multiple, bilateral resistant plantar warts. RESULTS: A complete clearance of the plantar warts was observed after three sessions of intralesional autologous PRP injections with one-month interval, combined with twice-daily local application of salicylic acid 30% solution between sessions. No recurrence was recorded after a nine-month follow-up from the last session. There were no reported side effects during or after the sessions. CONCLUSION: The combined intralesional autologous PRP injection with topical salicylic acid is an effective, economic, and safe modality of treatment for multiple resistant plantar warts.
