Kore VB, Anjankar A. A Comprehensive Review of Treatment Approaches for Cutaneous and Genital Warts. Cureus 2023; 15:e47685. [PMID: 38022045 PMCID: PMC10673707 DOI: 10.7759/cureus.47685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 10/25/2023] [Indexed: 12/01/2023] Open
Abstract
Cutaneous and genital warts are common in both developed as well as developing countries. Human papillomavirus (HPV), which is a double-stranded DNA virus, is the causative agent of wart infection. Different types of HPV viruses are responsible for the different severity of diseases. Some types are associated with malignancy of the anal region and cervix. HPV is a common sexually transmitted disease in the United States. The incidence is most common in the younger age groups and the elderly population. Our main goal is to describe the different treatment modalities available for warts. Treatment modalities are divided into primary, secondary, and tertiary options. Topical medications, and physical excision of warts via cryotherapy, electrocautery, lasers, or photodynamic therapy are all common forms of treatment. Various clinical trials and randomized control trials have been seen as effective treatment against HPV infection. Higher remission rates are seen irrespective of different treatment options. Warts can be treated but the HPV virus cannot be completely removed. Older age, immunocompromised state, diabetes mellitus, and HIV are the predisposing factors for the disease. There is currently a large variety of medicines in use, all of which can differ significantly in terms of price, side-effect profiles, dosing regimens, length of therapy, and overall effectiveness. The best course of treatment has not yet been identified, and patients are often treated according to their unique needs.

Abstract
Papillomaviruses (PVs) cause disease in humans, dogs, cats, and horses. While there are some differences, many aspects of the pathogenesis, presentation, and treatment of these diseases are similar between the four species. In this review, the PV-induced diseases of humans are compared to the similar diseases that develop in the companion animal species. By comparing with the human diseases, it is possible to make assumptions about some of the less common and less well-studied diseases in the veterinary species. In the first part of this review, the PV lifecycle is discussed along with the classification of PVs and the immune response to PV infection. The hyperplastic diseases caused by PVs are then discussed; including PV-induced cutaneous, anogenital, and oral warts within the four species.

Seroprevalence of mucosal and cutaneous human papillomavirus (HPV) types among children and adolescents in the general population in Germany. BMC Infect Dis 2022; 22:44. [PMID: 35012452 PMCID: PMC8751243 DOI: 10.1186/s12879-022-07028-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 12/28/2021] [Indexed: 11/30/2022] Open
Abstract
Background In Germany, HPV vaccination of adolescent girls was introduced in 2007. Nationally representative data on the distribution of vaccine-relevant HPV types in the pre-vaccination era are, however, only available for the adult population. To obtain data in children and adolescents, we assessed the prevalence and determinants of serological response to 16 different HPV types in a representative sample of 12,257 boys and girls aged 1–17 years living in Germany in 2003–2005. Methods Serum samples were tested for antibodies to nine mucosal and seven cutaneous HPV types. The samples had been collected during the nationally representative German Health Interview and Examination Survey for Children and Adolescents in 2003–2006. We calculated age- and gender-specific HPV seroprevalence. We used multivariable regression models to identify associations between demographic and behavioral characteristics and HPV seropositivity. Results We found low but non-zero seroprevalence for the majority of tested HPV types among children and adolescents in Germany. The overall seroprevalence of HPV-16 was 2.6%, with slightly higher values in adolescents. Seroprevalence of all mucosal types but HPV-6 ranged from 0.6% for HPV-33, to 6.4% for HPV-31 and did not differ by gender. We found high overall seroprevalence for HPV-6 with 24.8%. Cutaneous HPV type seroprevalence ranged from 4.0% for HPV-38 to 31.7% for HPV-1. In the majority of cutaneous types, seroprevalence did not differ between boys and girls, but increased sharply with age, (e.g., HPV-1 from 1.5% in 1–3-years-old to 45.1% in 10–11-years-old). Associations between behavioral factors and type-specific HPV prevalence were determined to be heterogeneous. Conclusions We report the first nationally representative data of naturally acquired HPV antibody reactivity in the pre-HPV-vaccination era among children and adolescents living in Germany. These data can be used as baseline estimates for evaluating the impact of the current HPV vaccination strategy targeting 9–14-years-old boys and girls.

Abstract
BACKGROUND Atopic dermatitis (AD) is associated with altered skin barrier, microbiome, and immune dysregulation that may increase risk of skin infections. OBJECTIVE The aim of the study was to determine whether AD is associated with skin infections and related outcomes. METHODS Data from the 2006 to 2012 National Emergency Department Sample were analyzed, including an approximately 20% sample of all US emergency department (ED) visits (N = 198,102,435 adults or children). RESULTS Skin infections were increased in ED visits of adults (7.14% vs 3.76%) and children (5.15% vs 2.48%) with AD. In multivariable logistic regression models, AD was associated with significantly higher odds of skin infection in adults (adjusted odds ratio [95% confidence interval] = 1.93 [1.89-1.97]) and children (2.23 [2.16-2.31]). Pediatric and adult AD were associated with significantly higher odds of carbuncle/furuncles, impetigo, cellulitis, erysipelas, methicillin-resistant and methicillin-sensitive Staphylococcus aureus infections, molluscum contagiosum, cutaneous warts, herpes simplex and zoster viruses, eczema herpeticum, dermatophytosis, and candidiasis of skin/nails and vulva/urogenitals. Adults with AD had significantly higher odds of genital warts (1.51 [1.36-1.52]) and herpes (1.23 [1.11-1.35]). Skin infections were associated with US $19 million excess annual costs of ED care in persons with AD. CONCLUSIONS Atopic dermatitis patients had higher odds of multiple bacterial, viral, fungal, and sexually transmitted skin infections.

Abstract
OBJECTIVE Atopic dermatitis (AD) is a chronic pruritic inflammatory skin disease with substantial patient and population burdens. A number of comorbid health problems occur in patients with AD, aside from the cutaneous signs and symptoms. This review summarizes recent developments in the burden and comorbidities of AD. DATA SOURCES Literature review. STUDY SELECTIONS Nonsystematic. RESULTS Different aspects of AD, such as chronic pruritus, psychosocial distress, and inflammation, can lead to anxiety, depression, or suicidality. Atopic dermatitis is associated with and may predispose to higher risk of other atopic disorders, including asthma, hay fever, food allergy, and eosinophilic esophagitis. Persons with AD appear to be at higher risk for infectious and cardiovascular risk. CONCLUSION Atopic dermatitis is associated with substantial burden and comorbidities. Identifying AD comorbidities is essential for proper disease management and improving overall patient outcomes.

Abstract
BACKGROUND Photodynamic therapy (PDT) is one of the treatment options for generalized facial flat warts, which results in elimination of virus and inhibition of proliferation of warts due to photochemical and phototoxic reactions. In this research, we attempted to evaluate the efficacy and safety profiles of a combination of 2940-nm laser and PDT for the treatment of generalized recalcitrant facial flat warts. METHODS Retrospective analysis of the patients with recalcitrant facial warts was performed. Patients in the combined group (n = 40) were treated with a 2940-nm single spot abrasion followed by a PDT; while the PDT group (n = 40) received a PDT treatment only. The efficacy was assessed by the lesion numbers and lesion clearance rate. The effective rate was calculated with the cured and excellent response rates. RESULTS The combined group showed significant improvements in the total effective rate (77.5%vs. 57.5%, p = 0.0416) and average clearance rate (81.68±2.83% vs. 68.13 ± 3.97%, p = 0.0068) as compared with the PDT-only group. The degree of lesion clearance was positively correlated with the treatment times in both groups. After three months of follow-up, no relapse occurred in patients from either group. Furthermore, an accumulation of photosensitizer in the lesional areas was observed in the combined treatment group. CONCLUSIONS A combination of 2940-nm laser and PDT was safe and showed significantly more effect than PDT alone in treatment for recalcitrant facial flat warts, partially due to the improved uptake of photosensitizer after 2940-nm laser induced skin abrasion.

Abstract
In this study, the hands and feet of 15,384 undergraduate and postgraduate students in 3 colleges in Beijing were examined for the presence of cutaneous warts at college-entry, and those diagnosed with warts were followed up 2-3 years later. We identified totally 215 (1.4%; 95% CI, 1.2-1.6%) students with warts. The prevalence was significantly higher in male than in female students (2.0% vs. 0.9%, P < 0.0001). Of the 215 patients, 66.9% and 62.1% had only one wart and 98.3% and 93.2% had warts <1 cm in diameter, on the hands and feet, respectively. Of the 130 patients with a follow-up visit, 78 did not receive any treatment (44 recovered within 2 years). Patients aged 21-25 compared to those aged ≤20 were more likely to be free of warts (hazard ratio = 1.76; 95% CI, 1.07-2.89), while lower father's education (hazard ratio = 0.19; 95% CI, 0.04-0.98) and poor sleep quality (hazard ratio = 0.41; 95% CI, 0.18-0.92) decreased the likelihood of resolution. The prevalence of warts is 1.4% in college students. The majority of patients have warts <1 cm and approximately 2/3 patients has one wart. Slightly over half of patients recover spontaneously within 2 years. Patients' age, sleep quality, and paternal education may affect the resolution.

Abstract
Verruca vulgaris (VV) is a prevalent skin condition caused by various subtypes of human papilloma virus (HPV). The most common causes of non-genital lesions are HPV types 2 and 4, and to a lesser extent types 1, 3, 26, 29, and 57. Although numerous therapeutic modalities exist, none is universally effective or without adverse events (AE). Pulsed dye laser (PDL) is a favorable option due to its observed efficacy and relatively low AE rate. However, it is not known which verrucae are most likely to respond to PDL, or whether the causative viral subtype influences this response. The objective of this prospective blinded study was to assess whether the HPV subtype was predictive of response to PDL. For that matter, 26 verrucae from 26 immunocompetent patients were biopsied prior to treatment by PDL. HPV coding sequences were isolated and genotyped using PCR analysis. Patients were treated by PDL (595 nm wavelength, 5 mm spot size, 1.5 ms pulse duration, 12 J/cm2 fluence) once a month for up to 6 months, and clinical response was assessed. Binary logistic regression analysis and linear logistic regression analysis were used in order to evaluate statistical significance. Different types of HPV were identified in 22 of 26 tissue samples. Response to treatment did not correlate with HPV type, age, or gender. As no association between HPV type and response to PDL therapy could be established, it is therefore equally effective for all HPV types and remains a favorable treatment option for all VV.

Abstract
Loss-of-function mutations in the common gamma (γc) chain cytokine receptor subunit give rise to severe combined immunodeficiency characterized by lack of T and natural killer cells and infant death from infection. Hematopoietic stem cell transplantation or gene therapy offer a cure, but despite successful replacement of lymphoid immune lineages, a long-term risk of severe cutaneous human papilloma virus infections persists, possibly related to persistent γc-deficiency in other cell types. Here we show that keratinocytes, the only cell type directly infected by human papilloma virus, express functional γc and its co-receptors. After stimulation with the γc-ligand IL-15, γc-deficient keratinocytes show significantly impaired secretion of specific chemokines including CXCL1, CXCL8, and CCL20, resulting in reduced chemotaxis of dendritic cells and CD4+ T cells. Furthermore, γc-deficient keratinocytes also exhibit defective induction of T-cell chemotaxis in a model of stable human papilloma virus-18 infection. These findings suggest that persistent γc-deficiency in keratinocytes alters immune cell recruitment to the skin, which may contribute to the development and persistence of warts in this condition and would require different treatment approaches.

Abstract
OBJECTIVE To investigate the clinical effectiveness of silver nitrate (95%) for the treatment of verruca pedis comparing professional and self-application treatments. METHODS A single-centre, two-armed randomized evaluation was conducted at a University podiatry clinic. A total of 113 participants (101 analysed) with verruca pedis were included. Participants were randomized to either a clinical group, where silver nitrate was applied by a healthcare professional or a home group, where silver nitrate was self-applied. The main outcome measure was post-treatment pain, controlling for pre-treatment pain, and resolution of the verruca. Secondary outcome measures were participant satisfaction, partial reduction in the verruca and ease of use of the product. KEY FINDINGS The study showed no significant difference between home treatment and clinically applied treatment for the treatment of verruca pedis in either primary outcome; however, a substantive difference in resolution between groups was recorded, with 34.0% full resolution and 26.4% partial resolution in the clinical treatment group, and 18.8% full resolution and 37.5% partial resolution in the home treatment group. Participants widely reported general ease of use of the product. All participants reported a reduction in pain as a result of the intervention. CONCLUSION Silver nitrate has been shown to be a safe and effective treatment for verruca pedis, with equal success rates when compared between home and clinical applications.

Abstract
Background Warts are common dermatological lesion caused by skin epithelial cells’ infection with human Papillomavirus (HPV). Objectives This study aimed to assess the efficacy of a new method for the treatment of dermal warts. Patients and Methods In this clinical trial study, 60 patients (older than 10 years) with dermal warts living in Baneh city, west of Iran, were allocated into the intervention and control groups using the block randomized method in 2012. In the intervention group, outer layers of the dermal wart carved using scalpel and HD tablet set on it and covered with adhesive. In the second and third days, it was repeated again. All stages in the intervention group were similar to the placebo group. Placebo was prepared by a pharmacologist, which was similar to the HD tablet. In both groups, patients were examined one week and one month after taking the last tablet by the physician in terms of improvement or lack of improvement. Data were analyzed by SPSS software version 18 using chi-square test, Fisher’s exact test, Mann-Whitney test and ANOVA for repeated measures. Results In the first week after the intervention, warts were changed in 93.3% of the cases; however, no changes were recorded in the control group. One month after follow-up, the mean was 0.4 ± 0.7 in the intervention group and 5.5 ± 4.9 in the control group (P = 0.0001). Based on ANOVA for repeated measures and t-test, the average number of warts, before, one week and one month after the intervention was statistically significant for both intervention (P = 0.009) and control groups (P = 0.0001). Conclusions This method is recommended for the treatment of dermal warts, owing to the effectiveness, short duration of treatment, and low cost of topical treatment for dermal warts using HD tablets.

Abstract
PURPOSE Because cutaneous warts resolve spontaneously and available treatments often fail, family physicians and patients may consider a wait-and-see policy. We examined the natural course of cutaneous warts and treatment decisions in a prospective observational cohort of primary schoolchildren. METHODS We inspected the hands and feet of children aged 4 to 12 years from 3 Dutch primary schools for the presence of warts at baseline and after a mean follow-up of 15 months. Parental questionnaires at follow-up provided information on inconvenience caused by warts and any treatments used. RESULTS Of the 1,134 eligible children, 1,099 (97%) participated, of whom 366 (33%) had cutaneous warts at baseline. Among these children with warts, loss to follow-up was 9% and the response rate to the parental questionnaires was 83%. The complete resolution rate was 52 per 100 person-years at risk (95% CI, 44-60). Younger age (hazard ratio = 1.1 per year decrease; 95% CI, 1.0-1.2) and non-Caucasian skin type (hazard ratio = 2.0; 95% CI, 1.3-2.9) increased the likelihood of resolution. During follow-up, 38% of children with warts at baseline treated their warts: 18% used over-the-counter treatment only, 15% used a family physician-provided treatment only, and 5% used both. Children were more likely to initiate treatment if the warts measured at least 1 cm in diameter (odds ratio = 3.2; 95% CI, 1.9-5.3) and especially if parents reported that the warts caused inconvenience (odds ratio = 38; 95% CI, 16-90). CONCLUSIONS One-half of primary schoolchildren with warts will be free of warts within 1 year. Young age and non-Caucasian skin type enhance resolution. Children with large or inconvenient warts are more likely to start treatment. These findings will be useful in the process of shared decision making with parents and children.

Abstract
Human papillomaviruses (HPVs) are ubiquitous, well adapted to their host and cleverly sequestered away from immune responses. HPV infections can be productive, subclinical or latent in both skin and mucosa. The causal association of HPV with cervical cancer, and increasingly with rising numbers of squamous cell carcinomas at other sites in both men and women, is increasingly recognised, while the morbidity of cutaneous HPV lesions, particularly in the immunosuppressed population is also significant. This chapter sets out the range of infections and clinical manifestations of the consequences of infection and its persistence and describes why HPVs are both highly effective pathogens and carcinogens, challenging to eliminate.

Abstract
BACKGROUND AND OBJECTIVE Cutaneous warts are common in primary schoolchildren; however, knowledge on the routes of transmission of human papillomavirus (HPV) causing warts is scarce. This study examines the association between the degree of HPV exposure and incidence of warts in primary schoolchildren to support evidence-based recommendations on wart prevention. METHODS In this prospective cohort study, the hands and feet of all children in grades 1 to 7 (aged 4-12 years) of 3 Dutch primary schools were inspected for the presence of warts at baseline and after 11 to 18 months of follow-up. Data on the degree of HPV exposure included information obtained from parental questionnaires: preexistent warts, warts in family, prevalence of warts at baseline in the class, and use of public places (eg, swimming pools). RESULTS Of the 1134 eligible children, 97% participated; the response rate from parental questionnaires was 77%, and loss to follow-up was 9%. The incidence for developing warts was 29 per 100 person-years at risk (95% confidence interval [CI] 26-32). Children with a white skin type had an increased risk of developing warts (hazard ratio [HR] 2.3, 95% CI 1.3-3.9). Having family members with warts (HR 2.08, 95% CI 1.52-2.86) and wart prevalence in the class (HR 1.20 per 10% increase, 95% CI 1.03-1.41) were independent environmental risk factors. CONCLUSIONS The degree of HPV exposure in the family and school class contributes to the development of warts in schoolchildren. Preventive recommendations should focus more on limiting HPV transmission in families and school classes, rather than in public places.

Abstract
Infection with human papillomavirus (HPV) is almost universal and eventually asymptomatic, but pathologic infection with HPV is severe, recurrent, and recalcitrant to therapy. It is also an underappreciated manifestation of primary immunodeficiency. Mutations in EVER1, EVER2, GATA2, CXCR4, and dedicator of cytokinesis 8 (DOCK8) are typically associated with extensive HPV infections, whereas several other primary immune defects result in severe HPV much less frequently. We review immunodeficiencies with severe HPV infections and the mechanisms underlying them.

Abstract
BACKGROUND Viral warts are a common skin condition, which can range in severity from a minor nuisance that resolve spontaneously to a troublesome, chronic condition. Many different topical treatments are available. OBJECTIVES To evaluate the efficacy of local treatments for cutaneous non-genital warts in healthy, immunocompetent adults and children. SEARCH METHODS We updated our searches of the following databases to May 2011: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, MEDLINE (from 2005), EMBASE (from 2010), AMED (from 1985), LILACS (from 1982), and CINAHL (from 1981). We searched reference lists of articles and online trials registries for ongoing trials. SELECTION CRITERIA Randomised controlled trials (RCTs) of topical treatments for cutaneous non-genital warts. DATA COLLECTION AND ANALYSIS Two authors independently selected trials and extracted data; a third author resolved any disagreements. MAIN RESULTS We included 85 trials involving a total of 8815 randomised participants (26 new studies were included in this update). There was a wide range of different treatments and a variety of trial designs. Many of the studies were judged to be at high risk of bias in one or more areas of trial design.Trials of salicylic acid (SA) versus placebo showed that the former significantly increased the chance of clearance of warts at all sites (RR (risk ratio) 1.56, 95% CI (confidence interval) 1.20 to 2.03). Subgroup analysis for different sites, hands (RR 2.67, 95% CI 1.43 to 5.01) and feet (RR 1.29, 95% CI 1.07 to 1.55), suggested it might be more effective for hands than feet.A meta-analysis of cryotherapy versus placebo for warts at all sites favoured neither intervention nor control (RR 1.45, 95% CI 0.65 to 3.23). Subgroup analysis for different sites, hands (RR 2.63, 95% CI 0.43 to 15.94) and feet (RR 0.90, 95% CI 0.26 to 3.07), again suggested better outcomes for hands than feet. One trial showed cryotherapy to be better than both placebo and SA, but only for hand warts.There was no significant difference in cure rates between cryotherapy at 2-, 3-, and 4-weekly intervals.Aggressive cryotherapy appeared more effective than gentle cryotherapy (RR 1.90, 95% CI 1.15 to 3.15), but with increased adverse effects.Meta-analysis did not demonstrate a significant difference in effectiveness between cryotherapy and SA at all sites (RR 1.23, 95% CI 0.88 to 1.71) or in subgroup analyses for hands and feet.Two trials with 328 participants showed that SA and cryotherapy combined appeared more effective than SA alone (RR 1.24, 95% CI 1.07 to 1.43).The benefit of intralesional bleomycin remains uncertain as the evidence was inconsistent. The most informative trial with 31 participants showed no significant difference in cure rate between bleomycin and saline injections (RR 1.28, 95% CI 0.92 to 1.78).Dinitrochlorobenzene was more than twice as effective as placebo in 2 trials with 80 participants (RR 2.12, 95% CI 1.38 to 3.26).Two trials of clear duct tape with 193 participants demonstrated no advantage over placebo (RR 1.43, 95% CI 0.51 to 4.05).We could not combine data from trials of the following treatments: intralesional 5-fluorouracil, topical zinc, silver nitrate (which demonstrated possible beneficial effects), topical 5-fluorouracil, pulsed dye laser, photodynamic therapy, 80% phenol, 5% imiquimod cream, intralesional antigen, and topical alpha-lactalbumin-oleic acid (which showed no advantage over placebo).We did not identify any RCTs that evaluated surgery (curettage, excision), formaldehyde, podophyllotoxin, cantharidin, diphencyprone, or squaric acid dibutylester. AUTHORS' CONCLUSIONS Data from two new trials comparing SA and cryotherapy have allowed a better appraisal of their effectiveness. The evidence remains more consistent for SA, but only shows a modest therapeutic effect. Overall, trials comparing cryotherapy with placebo showed no significant difference in effectiveness, but the same was also true for trials comparing cryotherapy with SA. Only one trial showed cryotherapy to be better than both SA and placebo, and this was only for hand warts. Adverse effects, such as pain, blistering, and scarring, were not consistently reported but are probably more common with cryotherapy.None of the other reviewed treatments appeared safer or more effective than SA and cryotherapy. Two trials of clear duct tape demonstrated no advantage over placebo. Dinitrochlorobenzene (and possibly other similar contact sensitisers) may be useful for the treatment of refractory warts.

Abstract
BACKGROUND Plantar warts (verrucae) are extremely common. Although many will spontaneously disappear without treatment, treatment may be sought for a variety of reasons such as discomfort. There are a number of different treatments for cutaneous warts, with salicylic acid and cryotherapy using liquid nitrogen being two of the most common forms of treatment. To date, no full economic evaluation of either salicylic acid or cryotherapy has been conducted based on the use of primary data in a pragmatic setting. This paper describes the cost-effectiveness analysis which was conducted alongside a pragmatic multicentre, randomised trial evaluating the clinical effectiveness of cryotherapy versus 50% salicylic acid of the treatment of plantar warts. METHODS A cost-effectiveness analysis was undertaken alongside a pragmatic multicentre, randomised controlled trial assessing the clinical effectiveness of 50% salicylic acid and cryotherapy using liquid nitrogen at 12 weeks after randomisation of patients. Cost-effectiveness outcomes were expressed as the additional cost required to completely cure the plantar warts of one additional patient. A NHS perspective was taken for the analysis. RESULTS Cryotherapy costs on average £101.17 (bias corrected and accelerated (BCA) 95% CI: 85.09-117.26) more per participant over the 12 week time-frame, while there is no additional benefit, in terms of proportion of patients healed compared with salicylic acid. CONCLUSIONS Cryotherapy is more costly and no more effective than salicylic acid.

Abstract
OBJECTIVE To compare the clinical effectiveness of cryotherapy versus salicylic acid for the treatment of plantar warts. DESIGN A multicentre, open, two arm randomised controlled trial. SETTING University podiatry school clinics, NHS podiatry clinics, and primary care in England, Scotland, and Ireland. PARTICIPANTS 240 patients aged 12 years and over, with a plantar wart that in the opinion of the healthcare professional was suitable for treatment with both cryotherapy and salicylic acid. INTERVENTIONS Cryotherapy with liquid nitrogen delivered by a healthcare professional, up to four treatments two to three weeks apart. Patient self treatment with 50% salicylic acid (Verrugon) daily up to a maximum of eight weeks. MAIN OUTCOME MEASURES Complete clearance of all plantar warts at 12 weeks. Secondary outcomes were (a) complete clearance of all plantar warts at 12 weeks controlling for age, whether the wart had been treated previously, and type of wart, (b) patient self reported clearance of plantar warts at six months, (c) time to clearance of plantar wart, (d) number of plantar warts at 12 weeks, and (e) patient satisfaction with the treatment. RESULTS There was no evidence of a difference between the salicylic acid and cryotherapy groups in the proportions of participants with complete clearance of all plantar warts at 12 weeks (17/119 (14%) v 15/110 (14%), difference 0.65% (95% CI -8.33 to 9.63), P=0.89). The results did not change when the analysis was repeated but with adjustment for age, whether the wart had been treated previously, and type of plantar wart or for patients' preferences at baseline. There was no evidence of a difference between the salicylic acid and cryotherapy groups in self reported clearance of plantar warts at six months (29/95 (31%) v 33/98 (34%), difference -3.15% (-16.31 to 10.02), P=0.64) or in time to clearance (hazard ratio 0.80 (95% CI 0.51 to 1.25), P=0.33). There was also no evidence of a difference in the number of plantar warts at 12 weeks (incident rate ratio 1.08 (0.81 to 1.43), P=0.62). CONCLUSIONS Salicylic acid and the cryotherapy were equally effective for clearance of plantar warts.

Abstract
Current evidence is strong enough to conclude that human papillomavirus (HPV) can be transmitted both sexually and non-sexually. The debate on HPV infections in children still continues but it is more focused on HPV prevalence than on transmission modes. HPV DNA detection in amniotic fluid, foetal membranes, cord blood and placental trophoblastic cells all suggest HPV infection in utero, i.e. prenatal transmission. Based on recent meta-analysis, vertical transmission occurs in approximately 20% of cases. Most of the mucosal HPV infections in infants are incident, persistent infections in oral and genital mucosa being found in less than 10% and 2% respectively. The mother seems to be the main transmitter of HPV to her newborn, but subsequent HPV infections are acquired horizontally via saliva or other contacts. Bimodal peak prevalence is seen for skin warts, oral papillomas and recurrent respiratory papillomatosis (RRP) in younger and older age groups, suggesting similar epidemiology. Of the clinical HPV diseases, juvenile-onset-RRP and genital condylomata are problematic; the former because of its life-threatening potential and the latter because of possible sexual abuse. HPV6 and 11 are the most common genotypes in both the lesions. Early in life, infections by the high-risk HPV genotypes may also remain persistent for a considerable period, and should be of considerable importance for HPV vaccination strategies.

Abstract
Cutaneous warts occur in 3.9-4.9% of children in the UK. The incidence is increased in organ transplant recipients and may be increased in patients with chronic kidney disease (CKD), since uraemia reduces the immune system's function. We surveyed the records from our CKD and renal transplant clinic to ensure patients with warts were identified and appropriately treated. Data were collected by questionnaire. The presence of warts, location, treatment, levels of pain and emotional upset were recorded. Nine of 49 (18.4%) pre-transplantation patients (33 male, median age 12.1 years) were currently suffering from warts compared with 17 of 60 (28.3%) post-transplantation patients (34 male, median age 13.9 years). A further 14 pre-transplantation and 16 post-transplantation patients had previously suffered from warts which had resolved. Forty-one patients had sought treatment for warts, mainly from primary care. Five patients, all having received transplants, were seen by a dermatologist. Self-rated levels of pain and emotional upset were generally low, apart from those of four adolescent patients who expressed significant emotional upset. We concluded that cutaneous warts are more common among CKD patients. Appropriate information and treatment are required before and after transplantation. The majority of warts can be treated in primary care, but selected patients with extensive warts that cause distress need early referral for dermatology opinion.

Abstract
Warts are a common pediatric skin disease. Most treatments show only modest benefit, and some are poorly tolerated because of pain. 5-fluorouracil interferes with deoxyribonucleic acid and ribonucleic acid synthesis, and is used to treat genital warts in adults. Efficacy, safety, and tolerability of topical 5% 5-fluorouracil for treatment of common warts were examined in an open-label pilot study with pediatric patients. Thirty-nine children who have at least two hand warts applied 5% 5-fluorouracil cream (Efudex, Valeant Pharmaceuticals International) once or twice daily, under occlusion for 6 weeks. Assessment of treatment response and side effects was performed at baseline, treatment completion, and 3- and 6-month follow-ups. Hematology measures, liver function tests, and medication blood levels were reassessed at treatment completion. Eighty-eight percent of treated warts improved after 6 weeks of treatment, and 41% of subjects had complete resolution of at least one wart. Treatment response did not differ between once or twice daily applications. Tolerability and patient satisfaction were excellent. No subject had clinically significant blood levels of 5-fluorouracil. At 6 month follow-up, 87% of complete responders had no wart recurrence. Topical 5% 5-fluorouracil is a safe, effective, and well-tolerated treatment for warts in children.

Abstract
BACKGROUND Warts are very common in primary schoolchildren. However, knowledge on wart epidemiology and causes of wart transmission is scarce. OBJECTIVES To determine the prevalence of warts in primary schoolchildren and to examine the relation with environmental factors in order to provide direction for well-founded recommendations on wart prevention. METHODS In this cross-sectional study, the hands and feet of 1465 children aged 4-12 years from four Dutch primary schools were examined for the presence of warts. In addition, the children's parents completed a questionnaire about possible environmental risk factors for warts. RESULTS Thirty-three per cent of primary schoolchildren had warts (participation rate 96%). Nine per cent had hand warts, 20% had plantar warts and 4% had both hand and plantar warts. Parental questionnaires (response rate 76%) showed that environmental factors connected to barefoot activities, public showers or swimming pool visits were not related to the presence of warts. An increased risk of the presence of warts was found in children with a family member with warts [odds ratio (OR) 1.9, 95% confidence interval (CI) 1.3-2.6] and in children where there was a high prevalence of warts in the school class (OR per 10% increase in wart prevalence in school class 1.6, 95% CI 1.5-1.8). CONCLUSIONS One-third of primary schoolchildren have warts. This study does not find support for generally accepted wart prevention recommendations, such as wearing protective footwear in communal showers and swimming pool changing areas. Rather, recommendations should focus on ways to limit the transmission of wart viruses within families and school classes.

Abstract
The natural history of infections with many human papillomavirus (HPV) types is poorly understood. Here, we describe for the first time the age- and sex-dependent antibody prevalence for 29 cutaneous and five mucosal HPV types from 15 species within five phylogenetic genera (alpha, beta, gamma, mu, nu) in a general population. Sera from 1,797 German adults and children (758 males and 1,039 females) between 1 and 82 years (median 37 years) were analysed for antibodies to the major capsid protein L1 by Luminex-based multiplex serology. The first substantial HPV antibody reactions observed already in children and young adults are those to cutaneous types of the genera nu (HPV 41) and mu (HPV 1, 63). The antibody prevalence to mucosal high-risk types, most prominently HPV 16, was elevated after puberty in women but not in men and peaked between 25 and 34 years. Antibodies to beta and gamma papillomaviruses (PV) were rare in children and increased homogeneously with age, with prevalence peaks at 40 and 60 years in women and 50 and 70 years in men. Antibodies to cutaneous alpha PV showed a heterogeneous age distribution. In summary, these data suggest three major seroprevalence patterns for HPV of phylogenetically distinct genera: antibodies to mu and nu skin PV appear early in life, those to mucosal alpha PV in women after puberty, and antibodies to beta as well as to gamma skin PV accumulate later in life.

Abstract
Viral warts are common in poor rural settings but their relationship to malnutrition has not been studied. We sought to determine the prevalence of warts in children of two communities in Oaxaca, Mexico, and compared it with their nutritional status. Children from Santa Catarina Yahuio and Santiago Laxopa of the state of Oaxaca were examined. Localization, number, and type of verruca were noted. Date of birth, height, and weight were obtained to determine nutritional status. A total of 213 children (116 girls and 97 boys), 107 in Yahuio and 106 in Laxopa, were studied. Mean age was 10.24 years. Thirty children (14.1%) had warts and 80% (24/30) of these lived in Yahuio (p = 0.0002). Almost half were teenagers. Most lesions were on sun-exposed areas. First degree malnutrition was found in 24.5%; second degree in 23.6% and third degree in 14.2%. A higher frequency of warts than previously reported was found. Malnutrition was prevalent in both groups but did not correlate positively with verruca. Verruca were more frequent in females, adolescents, sun-exposed areas, and higher altitude. We believe that the higher altitude of Yahuio facilitates greater exposure to ultraviolet light-induced immune suppression.

Abstract
Although cutaneous warts are one of the most common skin conditions affecting children, their management can be challenging, especially in complex cases and even more so during a single emergency department encounter. Anogenital warts require particular attention because of their possible but nonspecific association with sexual abuse. This review will focus on cutaneous warts and anogenital warts, with a discussion of their recognition and treatment, especially in the emergency department. The medicolegal implications of anogenital warts in children are also reviewed.

Abstract
BACKGROUND Epidemiological study on childhood dermatoses performed by direct inspection of dermatologists is limited. OBJECTIVE To investigate the prevalence of selective childhood dermatoses in Taiwan. METHODS In a cross-sectional study carried out in June 2004, 4067 of 7851 children aged between 6 and 11 years living in the Kaohsiung County in south Taiwan were clinically surveyed and examined by two board-certified dermatologists (response rate 52%), regarding the point prevalence of acne, ephelides, warts, atopic dermatitis (AD), psoriasis, alopecia areata (AA) and keloid. RESULTS Acne vulgaris was found in girls and boys from the age of 6 and 7, respectively, with comedones being the earliest presentation. Ephelides were not infrequently observed in our children (prevalence rate 8.4%, 95% confidence interval, CI 7.9-9.3%). The prevalence of warts on hands was 2.4% (95% CI 1.9-2.9%). The prevalence of AD was 1.7% (95% CI 1.3-2.1%), without gender difference. There were only four cases of AA but no psoriasis was found. Keloid was identified in 13 boys and 10 girls, accounting for 0.6% (95% CI 0.598-0.602%) of the children. CONCLUSION Acne vulgaris is as common in Taiwan as in Western countries. Ephelides are not uncommon in our population with the main skin types III-IV. A clustered distribution of the wart infection was noted. The low prevalence of AD in Taiwan seems unaltered over the past decade. AA and psoriasis are rare in our series. Most keloids in our children are caused by BCG vaccination.

Abstract
BACKGROUND Several general practitioner (GP)-prescribed and over-the-counter therapies for warts and verrucae are available. However, the cost-effectiveness of these treatments is unknown. OBJECTIVES To compare the cost-effectiveness of different treatments for cutaneous warts. METHODS We designed a decision-analytic Markov simulation model based on systematic review evidence to estimate the cost-effectiveness of various treatments. The outcome measures studied are percentage of patients cured, cost of treatment and incremental cost-effectiveness ratio for each treatment, compared with no treatment, after 18 weeks. RESULTS Duct tape was most cost-effective but published evidence of its effectiveness is sparse. Salicylic acid was the most cost-effective over-the-counter treatment commonly used. Cryotherapy administered by a GP was less cost-effective than GP-prescribed salicylic acid and less cost-effective than cryotherapy administered by a nurse. CONCLUSIONS Duct tape could be adopted as the primary treatment for cutaneous warts if its effectiveness is verified by further rigorous trials. Nurse-administered cryotherapy is likely to be more cost-effective than GP-administered cryotherapy.

Abstract
Human papillomavirus infection is one of the most common and most distressing cutaneous diseases in patients with HIV infection. It is also a common, and often therapeutically challenging, infection in individuals who are immunologically competent. A wide range of therapeutic options exists for treating cutaneous human papillomavirus infections, but none is uniformly effective. In this report we describe a man with HIV-1 infection and disfiguring facial verruca vulgaris who demonstrated complete clinical response to intravenous cidofovir. Our report provides further support for the use of intravenous cidofovir as therapy for treatment-resistant and/or widespread cutaneous human papillomavirus infection.

Abstract
BACKGROUND Viral warts are common and usually harmless but very troublesome. A very wide range of local treatments are used. OBJECTIVES To assess the effects of different local treatments for cutaneous, non-genital warts in healthy people. SEARCH STRATEGY We searched the Cochrane Skin Group Specialised Register (March 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2005), MEDLINE (1966 to March 2005), EMBASE (1980 to March 2005) and a number of other biomedical databases. The references of all trials and selected review articles were also searched. In addition, we contacted pharmaceutical companies involved in local treatments for warts and experts in the field SELECTION CRITERIA Randomised controlled trials of local treatments for cutaneous non-genital viral warts in immunocompetent (healthy) people. DATA COLLECTION AND ANALYSIS Data was extracted and two authors independently selected the trials and assessed methodological quality. MAIN RESULTS Sixty trials were identified that fulfilled the criteria for inclusion. The evidence provided by these studies was generally weak due to poor methodology and reporting. In 21 trials with placebo groups that used participants as the unit of analysis, the average cure rate of placebo preparations was 27% (range 0 to 73%) after an average period of 15 weeks (range 4 to 24 weeks). The best available evidence was for simple topical treatments containing salicylic acid, which were clearly better than placebo. Data pooled from five placebo-controlled trials showed a cure rate of 117/160 (73%) compared with 78/162 (48%) in controls, which translates to a risk ratio of 1.60 (95% confidence interval 1.16 to 2.23), using a random effects model. Evidence for the absolute efficacy of cryotherapy was surprisingly lacking. Two trials comparing cryotherapy with salicylic acid and one comparing duct tape with cryotherapy showed no significant difference in efficacy. Evidence for the efficacy of the remaining treatments reviewed was limited. AUTHORS' CONCLUSIONS There is a considerable lack of evidence on which to base the rational use of topical treatments for common warts. The reviewed trials are highly variable in method and quality. Cure rates with placebo preparations are variable but nevertheless considerable. There is certainly evidence that simple topical treatments containing salicylic acid have a therapeutic effect. There is less evidence for the efficacy of cryotherapy, but reasonable evidence that it is only of equivalent efficacy to simpler and safer treatments. The benefits and risks of topical dinitrochlorobenzene and 5-fluorouracil, intralesional bleomycin and interferons, photodynamic therapy and other miscellaneous treatments remain to be determined.

Abstract
BACKGROUND Viral warts caused by the human papilloma virus represent one of the most common diseases of the skin. Any area of skin can be affected although the hands and feet are by far the commonest sites. A very wide range of local treatments are available. OBJECTIVES To assess the effects of different local treatments for cutaneous, non-genital warts in healthy people. SEARCH STRATEGY We searched the Cochrane Controlled Trials Register (January 2003), the Skin Group trials register (January 2003), MEDLINE (1966 to January 2003), EMBASE (1980 to January 2003) and a number of other key biomedical and health economics databases. In addition the cited references of all trials identified and key review articles were searched. Pharmaceutical companies involved in local treatments for warts and experts in the field were contacted. The most recent searches were carried SELECTION CRITERIA Randomised controlled trials of local treatments for cutaneous non-genital viral warts in immunocompetent human hosts were included. DATA COLLECTION AND ANALYSIS Study selection and assessment of methodological quality were carried out by two independent reviewers. MAIN RESULTS Fifty two trials were identified which fulfilled the criteria for inclusion in the review. The evidence provided by these studies was generally weak because of poor methodology and reporting. In 17 trials with placebo groups that used participants as the unit of analysis the average cure rate of placebo preparations was 30% (range 0 to 73%) after an average period of 10 weeks (range 4 to 24 weeks). The best available evidence was for simple topical treatments containing salicylic acid, which are clearly better than placebo. Data pooled from six placebo-controlled trials show a cure rate of 144/191 (75%) compared with 89/185 (48%) in controls, odds ratio 3.91 (95% confidence interval 2.40 to 6.36), random effects model. Most of the bigger trials of cryotherapy studied different regimens rather than comparing cryotherapy with other treatments or placebo. Pooled data from two small trials that included cryotherapy and placebo or no treatment, showed no significant difference in cure rates. In two trials comparing cryotherapy with salicylic acid and one comparing duct tape with cryotherapy no significant difference in efficacy was demonstrated. There was no consistent evidence for the effectiveness of intralesional bleomycin. Four studies, using warts rather than individuals as the unit of analysis, had widely varying results which could not be meaningfully pooled. There was some evidence for the efficacy of dinitrochlorobenzene, a potent contact sensitizer. Pooled data from two small studies comparing dinitrochlorobenzene with placebo showed cure rates of 32/40 (80%) and 15/40 (38%) respectively, odds ratio 6.67 (95% confidence interval 2.44 to 18.23), random effects model. Only limited evidence was found for the efficacy of topical 5-fluorouracil, intralesional interferons and photodynamic therapy.Bleomycin, dinitrochlorobenzene, 5-fluorouracil, interferons and photodynamic therapy are potentially hazardous or toxic treatments. REVIEWER'S CONCLUSIONS There is a considerable lack of evidence on which to base the rational use of the local treatments for common warts. The reviewed trials are highly variable in method and quality. Cure rates with placebo preparations are variable but nevertheless considerable. There is certainly evidence that simple topical treatments containing salicylic acid have a therapeutic effect. There is less evidence for the efficacy of cryotherapy and some evidence that it is only of equivalent efficacy to simpler, safer treatments. Dinitrochlorobenzene appears to be effective but there were no statistically significant differences when compared with the safer, simpler and cheaper topical treatments containing salicylic acid. The benefits and risks of 5-fluorouracil, bleomycin, interferons and photodynamic therapy remain to be determined.

Abstract
OBJECTIVE The aim of this study is to describe an outbreak of plantar warts and to analyse the risk factors wich determining the transmission. DESIGN Cross-sectional survey. SETTING A school of Alicante. PARTICIPANTS 1,620 students. MEASUREMENTS AND MAIN RESULTS Description and analysis of the outbreak. We studied the magnitude and the association between risk factors (sports activities and hygiene habits) and disease by logistic regression model. We estimated the crudes and adjusted odds ratio (OR) and the confidence intervals (CI) of 95%. We carry out environmental study and active search of cases. The global rate of answer to the cross-secctional survey was 70.86%. Reported cases were 221, the global attack rate was 19.25%. The outbreak occurred over 16 months. We did not find statistical significal difference either by sex (P=.138) or age (P=.233). The hygiene conditions of the swimming pool and the changing room were adapted. The risk of disease increased with the number of activities taking place (P=.001). The OR adjusted for hygiene habits was: use of changing room 0.95 (95% CI, 0.38%-2.41%), use of shower rooms 1.06 (95% CI, 0.70%-1.62%), walking barefoot in the changing room 1.97 (95% CI, 1.39%-2.79%) and showering barefoot 0.97 (95% CI, 0.58%-1.64%). CONCLUSIONS Outbreak of person to person transmission, the floor of the changing rooms was the prime cause of transmission. We did not find any association between the use of public swimming pool and the disease

Abstract
BACKGROUND This paper highlights the sometimes impressive effect of diphencyprone (DPC) sensitization on warts resistant to other treatments and is interesting in view of the fact that all the warts apparently responded, despite only a very small area being treated. METHODS A 31-year-old woman with a 5-year history of widespread facial plane warts that had proved resistant to repeated treatments with cryotherapy and topical preparations was sensitized to diphencyprone. RESULTS After application of DPC to the warts within only a 1-cm(2) area of the face, all the facial warts became inflamed and resolved, including those not actively treated. Complete clearance occurred with no recurrence. CONCLUSION DPC appears to be a valuable, safe and well-tolerated treatment for resistant viral warts and can be considered as a first line treatment. We review its use and action in this paper

Abstract
Although viral warts are common, their exact frequency in the community is often underestimated and not well recorded. A random sample of 2491 students from schools throughout the State of Victoria, Australia were examined by dermatologists and dermatology registrars to record the prevalence of common, plantar and plane warts. The overall prevalence of warts adjusted for the age and sex of Victorian school children was 22% (95% confidence interval (CI) 20.1-20.7) varying from 12% (95% CI 9.4-15.7) in 4-6 year olds to 24% (95% CI 18.3-30.4) in 16-18 year olds. Common warts were the most frequent (16%) compared with plantar warts (6%) and plane warts (2%). There was no difference in the overall frequency of warts between males and females and there was no difference in frequency between those who had eczema and those who did not. Almost 40% of those found to have warts on examination had indicated on the survey questionnaire that they did not have any of these lesions. Of those who knew that they had warts, only 38% had used any treatment for them. These data, the first community-based prevalence data on warts ever published from Australia, confirm that warts are indeed common. They suggest the need for education programmes in schools on the nature of these lesions and the treatment available.

Abstract
Warts are common skin infections caused by human papillomavirus (HPV) and affect most people sometime in their life. A number of epidemiological studies on the prevalence of warts have been completed in schools, various occupational groups, general practices and hospitals. All studies have relied on a subjective measure for the diagnosis of warts. Cross-sectional studies completed in schools have shown the prevalence in children to vary from 2 to 20%. Occupational handlers of meat, poultry and fish have a higher prevalence than other workers. Children and young adults are the groups most affected. Future studies are needed to investigate the true frequency of warts in the community and the likelihood of an individual developing these lesions during his/her lifetime.
