Bristow I. Paediatric Cutaneous Warts and Verrucae: An Update. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:16400.

Abstract
Cutaneous warts are common lesions in children caused by the Human Papilloma Virus (HPV) and for most lesions spontaneously resolve within months of the initial infection, regardless of treatment. The infection is most prevalent in the second decade of life affecting over 40% of children. Studies have demonstrated wart virus carriage on normal skin is higher in children with active lesions and family members. Subtypes HPV 2, HPV 27, HPV 57 and HPV 63 are particularly common in paediatric populations. Warts arising on the plantar surface of the foot (verrucae) can be particularly problematic owing to the location. They may interfere with daily activities causing pain and embarrassment. Plantar lesions have been shown to be more resistant to treatment than warts elsewhere on the skin. Systematic reviews and studies conducted over the last decade have demonstrated little evidence of innovation or effective improvements in treatment of recalcitrant lesions over the last 30 years. However, newer modalities such as immunotherapy (using injected vaccines) and hyperthermia using microwave treatment may hold promise in improving the treatment of these common and therapeutically frustrating lesions.

Thrombophilia Caused by Beta2-Glycoprotein I Deficiency: In Vitro Study of a Rare Mutation in APOH Gene. Curr Med Sci 2018; 38:379-385. [PMID: 30074200 DOI: 10.1007/s11596-018-1889-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Revised: 12/15/2017] [Indexed: 12/31/2022]
Abstract
This study aimed to explore the mechanism of a novel mutation (p.Lys38Glu) in apolipoprotein H (APOH) gene causing hereditary beta2-glycoprotein I (β2GPI) deficiency and thrombosis in a proband with thrombophilia. The plasma level of β2GPI was measured by ELISA and Western blotting, and anti-β2GPI antibody by ELISA. Lupus anticoagulant (LA) was assayed using the dilute Russell viper venom time. Deficiency of the major natural anticoagulants including protein C (PC), protein S (PS), antithrombin (AT) and thrombomodulin (TM) was excluded from the proband. A mutation analysis was performed by amplification and sequencing of the APOH gene. Wild type and mutant (c.112A>G) APOH expression plasmids were constructed and transfected into HEK293T cells. The results showed that the thrombin generation capacity of the proband was higher than that of the other family members. Missense mutation p.Lys38Glu in APOH gene and LA coexisted in the proband. The mutation led to β2GPI deficiency and thrombosis by impairing the protein production and inhibiting the platelet aggregation. It was concluded that the recurrent thrombosis of the proband is associated with the coexistence of p.Lys38Glu mutation in APOH gene and LA in plasma.

Comparison of clinical efficacy and safety of thermotherapy versus cryotherapy in treatment of skin warts: A randomized controlled trial. Dermatol Ther 2017; 31.

Abstract
The effect of thermotherapy in the treatment of skin warts in comparison to cryotherapy, as the standard conventional method, has remained uncertain. This study aimed to assess the clinical efficacy and safety of thermotherapy and cryotherapy in removing skin warts. This randomized controlled trial was conducted on 52 patients aged 18 years and over with ≤ 10 skin warts. The participants were randomly assigned into two groups to receive cryotherapy (every 2 to 3 weeks up to six sessions if required) or thermotherapy (one session). The patients in both groups were followed every 2 to 3 weeks for the first three months, and then three months after the last treatment session. The clearance rate was 79.2% in the thermotherapy group and 58.3% in the cryotherapy group with no significant difference (p = 0.212). The rate of scarring in the thermotherapy group was 20% (p = .018). A higher clearance rate was achieved in the thermotherapy group. However, this result was not statistically significant. There were some minimal post-treatment complications. Patients needed only one session of thermotherapy. Due to the risk of scarring, we suggest thermotherapy only as a suitable treatment method for palmoplantar warts.

Abstract
Cutaneous warts are caused by human papillomavirus infection. Immunosuppressive state is one of the risk factors of human papillomavirus infection. A girl diagnosed of nephrotic syndrome and on immunosuppressive therapy developed multiple common warts. We treated her on a single lesion by local hyperthermia therapy at 44 °C for 3 consecutive days, each therapy lasted for 30 min. Ten days later, the patient received another 2 consecutive therapy. All lesions are completely resolved at the 9th week after the treatment. No recurrent sign was observed in a 3-mo follow-up. Side effects included burning sensation, stabbing pain at the target site during treatment.

Abstract
Moxibustion is a treatment that uses thermal stimulation generated when herbal materials are burned, indirectly or directly, on the affected area or acupoint. Three cases are presented to report the efficacy of direct moxibustion on cutaneous warts. Three patients with chronic cutaneous warts received direct moxibustion made of Artemisia argyi (Dongbang Inc., Chungnam, Korea). Moxa burning was performed using moxa cones. Approximately 80% of a cone was burned, until patients reported feeling a burning sensation, at which time the cone was removed and another one burned. As part of this approach, patients underwent 5-19 moxibustion procedures during and after wart removal. After warts were completely eliminated, moxa burning was performed on each patient until approximately 60% of a cone was burned or the patient felt heat sensitization but no pain. In these cases, moxibustion seemed to have an effect on cutaneous warts. A possible mechanism is that direct moxibustion likely induces tissue damage from burning and, subsequently, a wound healing effect at a different temperature level. Our reports suggest that it would be worthwhile to conduct further studies on the safety and efficacy of moxibustion on warts or to develop a medical device that uses modified moxibustion.

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 Local hyperthermia has been successfully used in the treatment of viral warts. However, the mechanism of action has largely remained unclear. CCL-20 (also known as MIP-3α) is the most potent chemokine for recruitment of Langerhans cell (LC) precursors into the skin. CCL-20 expression can be increased by TNF-α and IL-1α. The effects of local hyperthermia on the mRNA expressions of CCL-20, TNF-α, IL-1α have been investigated in both condyloma acuminata (CA) and normal skin. Under an organotypic culture condition, fresh CA and normal skin were subjected to surface heating at 37°C, 42°C and 45°C for 30 mins, respectively. Results The mRNA expressions of CCL-20 and IL-1α in CA specimen were significantly higher than those in normal skin. Local hyperthermia at 42°C and 45°C significantly decreased the mRNA levels of CCL-20 and IL-1α, as compared with the control groups (p < 0.01). The decrease of CCL-20 was well correlated with that of IL-1α. The expression of TNF-α in CA remained unchanged in spite of the temperature variation. Local hyperthermia at 45°C concomitantly increased the mRNA expression of CCL-20 and IL-1α in normal skin. Conclusions Our study suggests that hyperthermia decreases the expression of CCL-20 with concomitant decrease in IL-1α, and reduce the number of Langerhans cells in HPV infected skin.

Abstract
Local hyperthermia has been successfully used in the treatment of viral warts by mechanisms that have largely remained unclear. Using an organotypic culture system, we found that hyperthermia at 42 °C and 45 °C could induce a significant increase in the transcriptional expression of interferon (IFN)-α, IFN-β and IFN-γ, in a temperature-dependent manner in condyloma acuminata (CA), but not in normal skin. Accordingly, local hyperthermia could enhance the expression of 2'-5' oligoadenylate synthase and double-stranded RNA (dsRNA)-dependent protein kinase, two antiviral enzymes downstream of the IFN-dependant pathway. Hyperthermia led to an increase in IFN-α/β receptor transcripts, and an increase in the levels in phospho-Stat1 and phospho-Stat2 in CA, though it had no influence on the levels of Jak1, Tyk2, Stat1 and Stat2 transcriptional expression. Local hyperthermia was proved effective in treating human papillomavirus-infected skin. These results suggested that hyperthermia took effect partly by inducing the expression of local endogenous IFN and partly by subsequent IFN-induced antiviral activity via Jak-STATs signalling pathway in CA.

Abstract
Local hyperthermia has been successfully used in the treatment of viral warts. However, the mechanism of action of hyperthermia has largely remained unclear. In this study we evaluated the effect of local hyperthermia on the induction of apoptosis in human keratinocytes, and expression of apoptosis-related genes in both condyloma acuminata (CA) and normal skin. The study showed that higher hyperthermia increased the number of apoptotic keratinocytes in CA and normal skin. The temperature-dependent increased expression of Fas and Bax were observed in both CA and normal skin. In contrast, the expression of Bcl-2 in CA was decreased at both transcriptional and translational levels. Furthermore, the transcriptional expression of DR4 and DR5 were increased in a temperature-dependent manner in CA, but not in normal skin. These results suggest that different mechanisms of action might be involved in hyperthermia induced apoptosis in CA and normal skin.

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 Cutaneous leishmaniasis (CL), rare in the first Gulf War, is common in American troops serving in Operation Iraqi Freedom. Awareness of the clinical features and treatment options of CL would benefit clinicians who may encounter soldiers, as well as civilians, returning from the Middle East with skin lesions. OBJECTIVE Our purpose was to describe our clinical experience in treating soldiers with CL. METHODS From December 2003 through June 2004, approximately 360 of an estimated 20,000 soldiers returning from a yearlong deployment in Iraq with skin lesions suspected of being CL were examined by dermatologists. We summarized CL diagnoses, laboratory evaluations, and treatments, including localized heat therapy (ThermoMed model 1.8; ThermoSurgery Technologies, Inc, Phoenix, Ariz), oral fluconazole, cryotherapy, and itraconazole. RESULTS Among 237 soldiers diagnosed with CL, 181 had one or more laboratory confirmations, most by Giemsa-stained lesion smears and polymerase chain reaction (PCR). PCR was positive for all 122 smear-positive and 26 biopsy-positive lesions and all 34 smear negative and all 3 biopsy-negative cases. Primary outpatient treatments, including ThermoMed (n = 26), oral fluconazole (n = 15), cryotherapy (n = 4), and itraconazole (n = 2), were safe and tolerable. Treatment failure occurred in 2 fluconazole recipients and was suspected in 1 ThermoMed and 2 fluconazole recipients. Seventy-two soldiers elected no treatment. LIMITATION This was a retrospective study. CONCLUSION Approximately 1% of Ft Campbell troops returning from Iraq were diagnosed with CL, most by laboratory confirmation. PCR appeared to be the most useful diagnostic technique. Among outpatient treatments, ThermoMed and cryotherapy had favorable safety and efficacy profiles.

Abstract
Cutaneous warts are benign epidermal proliferations caused by human papillomavirus infection. Treatment aims to cure the patient's physical and psychological discomfort, and to prevent the spread of infection by contact with other body areas or with other individuals. Among the available medical and destructive therapeutic options for cutaneous warts, none is uniformly effective or virucidal. Moreover, in most cases the safety and efficacy of these treatment options has not been assessed in randomized controlled trials, so that the reproducibility of many of the listed treatments is difficult to evaluate and a possible placebo effect cannot be ruled out. This article provides indications for the management of patients with cutaneous warts through an evidence-based approach, considering a first-, second-, and third-line therapy for each clinical form. The first line includes medical treatments useful to cure single, or few, and/or small common warts of short duration (<1 year). If these treatments have failed or are contraindicated, cryotherapy may be considered as second-line therapy. For recurrent or difficult-to-treat lesions, a third-line of therapy includes a variety of alternative therapeutic options that are in clinical use but are not necessarily approved by the US FDA, and their use may be further limited by adverse effects.

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
Cutaneous warts are a common malady that affects all ages, but are most prevalent in children and young adults. Warts result from infection with human papillomavirus and can lead to a condition that may be painful, disfiguring, and recurrent, despite treatment. A multitude of therapeutic modalities exist, though no single agent is invariably effective. Successful treatment must take into consideration the patient's level of motivation, expense, and physician experience.

Abstract
BACKGROUND Hyperthermia therapy was described previously to be effective for treating warts using a hot water technique as well as an ultrasound hyperthermia technique. Recently, two other papers described controlled localized heat therapy for cutaneous warts. A new heat-generated application system and method has been developed for treating warts using a self-administered, self-adhesive disposable exothermic patch. OBJECTIVE The objective of this study was to describe our clinical experience in using the exothermic patch to successfully treat patients with cutaneous recalcitrant warts who failed to respond to multiple antiwart therapy. METHODS Two patients with recalcitrant warts that did not respond to other therapeutic modalities were treated with the exothermic patch with complete remission of their warts. Exothermic patches were used in this study that were specially constructed to provide long-lasting, continuous, and reproducible heating of the skin surface for at least 2 hours at a temperature level of 42-43 degrees C, which will not burn or otherwise injure the skin. CONCLUSIONS Warts are difficult to treat in part because there are no specific anti-Papillomavirus drugs or methods available. We describe our clinical experience in successfully treating two patients with recalcitrant warts using the exothermic patch.

Abstract
Common warts are an important issue, especially in children and young adults. The methods proposed for common wart treatment are painful, destructive, and require special experience and devices. The chemical cauterization effect of silver nitrate on warts is noted in the classical pharmaceutical textbooks. In order to test this effect for this purpose, a placebo controlled clinical study was performed on 70 patients. On 35 randomly selected patients, a silver nitrate stick was used, and, on the other 35 patients, black ink was used. At the end of this study, of the patients treated with the silver nitrate stick, 15 (43%) were completely healed, 9 (26%) were partially healed, and 11 (31%) were not healed. Of the patients treated with black ink, 4 (11%) were completely healed, 5 (14%) were partially healed, and 26 (74%) patients were not affected. Thus the silver nitrate stick affected the warts of 24 (69%) patients. Therefore, this method appears to be an effective, economic, and easily applicable treatment for common warts.

Abstract
BACKGROUND The infrared coagulator (IRC) is an instrument that delivers a narrow beam of noncoherent infrared light to the skin surface. OBJECTIVE The purpose of the study was to determine the utility of the infrared coagulator in treating common warts of the hands and feet. METHODS Forty-four warts in 21 patients were treated with 1.25-second pulse durations. Thirty-one of the warts were recurrent after previous electrosurgery or cryosurgery. Average follow-up time was 11 months. RESULTS Overall, 25 warts (57%) resolved after one treatment, 6 warts (14%) regressed and cleared with additional treatment, and 13 warts (30%) recurred, giving an overall cure rate of 70%. Eleven of the 21 patients (52%) were cleared of all their treated warts. CONCLUSION The IRC is a useful therapeutic modality for common warts.
