Cantharidin (1%), podophyllin (5%), and salicylic acid (30%) formulation in recalcitrant plantar warts: Analysis of 48 patients.

A plantar wart is a benign hyperplasia that appears on the feet due to the human papillomavirus (HPV). One method used for the treatment of recalcitrant plantar warts, those lasting over 2 years or persisting after at least two treatment attempts, is the cantharidin (1%), podophyllin (5%), and salicylic acid (30%) formulation, also known as the CPS formulation. Although this method is in use, there are few studies on it. This study's objective was to ascertain its cure rate. For this retrospective observational study, we reviewed the medical records of patients treated with the CPS formulation at a podiatric clinic specializing in plantar wart treatment. Our sample size was 48 subjects. The CPS formulation had a cure rate of 62.5%. Out of the cured patients, 86.67% (26/30) required one or two applications. There was no observable correlation (p > 0.05) between wart resolution and virus biotype, evolution time, patient's morphological and clinical attributes, location, number of warts, or preceding treatments. The CPS formulation presents a relatively high efficacy rate for treating recalcitrant HPV plantar warts. Still, additional studies are necessary to evaluate its safety and efficiency.

Efficacy of Intralesional Candida Antigen Versus Measles, Mumps, and Rubella Vaccine Versus Topical Podophyllin in Treatment of Resistant Genital Warts.

BACKGROUND: No single treatment is ideal for genital warts with high rate of resistance using conventional modalities as topical podophyllin; however, several intralesional immunotherapies are being tested nowadays, with variable results. In this study, we compared the safety and efficacy of treating resistant and recurrent genital warts by 2 intralesional immunotherapies [Candida antigen and measles, mumps, and rubella (MMR) vaccine] and compared them with topical podophyllin. PATIENTS/METHODS: A total of 45 patients with resistant or recurrent genital warts were enrolled in this study. Size and number of warts were detected in each patient, patients were divided into 3 groups. Group A injected with intralesional Candida antigen. Group B with intralesional MMR vaccine. Group C were treated with topical 25% podophyllin. Patients received a session every 2 weeks for 3 treatment sessions. RESULTS: With regard to the reduction in size and number of all warts, the best response was obtained in Candida antigen group where 46.7% showed complete clearance and 40% showed partial response followed by MMR group and the last was the podophyllin group, with no significant difference between them. Complete clearance of mother warts was noticed in 86.7% of Candida group, 53.3% in MMR group, and last 40% in podophyllin group, with a significantly better response in the Candida group (P = .027). CONCLUSION: Both intralesional Candida antigen and MMR vaccine are simple, safe, and effective treatment options with comparable results and better response than topical podophyllin.

Podophyllin Toxicity: Case Report of a Rare Poisoning.

Podophyllin poisoning is a rare but serious emergency, often fatal, that involves multiple systems, predominantly the nervous system. Usually, it results from the resin extract derived from certain plants, and podophyllotoxin is the most toxic chemical present in it. The toxicity mechanisms involve suppression of cellular nucleoside transport and microtubule disruption. Due to the delayed onset of symptoms, there can be a delay in diagnosing and treating the condition. In addition, the initial and dominant central nervous system (CNS) symptoms can be mistaken for CNS infection or brainstem stroke. Therefore, early diagnosis (based on a high degree of suspicion, and circumstantial evidence) and prompt treatment (primarily decontamination and supportive care) are crucial to prevent unfavorable outcomes. We present a rare case of a 23-year-old male who accidentally ingested podophyllin and initially experienced severe neurological symptoms, subsequently developing into multisystem involvement and culminating in death within 4 days of its ingestion.

Intralesional bivalent human papilloma virus vaccine as a treatment for anogenital warts versus topical podophyllin resin 25%: A pilot study.

A role of human papilloma virus (HPV) vaccines as a therapy for genital warts was suggested, nevertheless; it has not been established in clinical trials and has yet to be determined. The objective of this study is to evaluate a potential benefit of intralesional injection of bivalent HPV (Cervarix) vaccine as a treatment for anogenital warts versus topical podophyllin resin 25%. Forty-four patients with anogenital warts were included in the study, 22 patients received intralesional Cervarix every 2 weeks until clearance of lesions or for a maximum of five sessions. The other 22 patients received topical podophyllin resin 25% twice weekly until complete resolution or for a maximum of 4 weeks. Follow up was done for 6 months. Dermatology life quality index (DLQI) was measured. Complete clearance of warts was achieved in 10 patients (45.5%) in Cervarix group versus six patients (27.3%) in Podophyllin group. The difference was statistically insignificant. No recurrence of warts was reported in Cervarix group while two patients (33.3%) showed recurrence in Podophyllin group. Both treatments were well tolerated. All patients reported significant improvement of their DLQI. Intralesional Cervarix is a promising modality showing higher rates of complete response, high safety, and no recurrence.

Radiosensitizer Effect of ß-Apopicropodophyllin against Colorectal Cancer via Induction of Reactive Oxygen Species and Apoptosis.

ß-apopicropodophyllin (APP), a derivative of podophyllotoxin (PPT), has been identified as a potential anti-cancer drug. This study tested whether APP acts as an anti-cancer drug and can sensitize colorectal cancer (CRC) cells to radiation treatment. APP exerted an anti-cancer effect against the CRC cell lines HCT116, DLD-1, SW480, and COLO320DM, with IC50 values of 7.88 nM, 8.22 nM, 9.84 nM, and 7.757 nM, respectively, for the induction of DNA damage. Clonogenic and cell counting assays indicated that the combined treatment of APP and γ-ionizing radiation (IR) showed greater retardation of cell growth than either treatment alone, suggesting that APP sensitized CRC cells to IR. Annexin V-propidium iodide (PI) assays and immunoblot analysis showed that the combined treatment of APP and IR increased apoptosis in CRC cells compared with either APP or IR alone. Results obtained from the xenograft experiments also indicated that the combination of APP and IR enhanced apoptosis in the in vivo animal model. Apoptosis induction by the combined treatment of APP and IR resulted from reactive oxygen species (ROS). Inhibition of ROS by N-acetylcysteine (NAC) restored cell viability and decreased the induction of apoptosis by APP and IR in CRC cells. Taken together, these results indicate that a combined treatment of APP and IR might promote apoptosis by inducing ROS in CRC cells.

Ingenol Mebutate Gel 0.05% in the Treatment of Anogenital Warts: A Prospective Controlled Trial Comparing It With Topical Podophyllin Solution 25.

BACKGROUND: Anogenital warts (AGWs) are a common therapeutic challenge. All therapies are associated with burning, pain, and frustrating high rate of recurrence. The search for a new alternative continues. Recently, a diterpene ester extracted from the Euphorbia peplus plant (ingenol mebutate [IM]) has been shown to possess activity against AGWs. OBJECTIVE: This study aimed to compare and evaluate the therapeutic efficacy and safety of topical 0.05% ingenol gel with another herbal extract medication (topical 25% podophyllin solution) in treatment of AGWs. METHODS: This was a comparative single blinded nonrandomized, 2-arm trial of ingenol 0.05% gel versus podophyllin solution 25% administered up to 6 times to patients with AGWs. To evaluate the therapeutic efficacy, the complete clearance rate and recurrence rate were assessed 1 and 12 weeks after last treatment, respectively. Safety was assessed by occurrence and severity of pain and local skin reaction (LSR). RESULTS: Of 31 and 36 patients in the IM group and podophyllin group who completed the study, initial complete resolution was observed in 20 (64.5%) and 14 (38.9%) patients, respectively (P = 0.03). The initial clearance was faster in the IM group (2.00 ± 0.91 weeks) compared with the podophyllin group (4.21 ± 1.05 weeks, P = 0.00). After 3 months, recurrence was seen in 13 (65.0%) of 20 patients in the IM group and 6 (42.8%) of 14 in the podophyllin group (P = 0.20). The number of patients with complete resolution after 3 months was not different between the 2 groups (7/31 in the IM group and 8/36 in the podophyllin group, P = 0.97). The mean ± SD severity scores for LSR and pain in the IM group were 6.65 ± 1.76 and 6.13 ± 2.57, respectively, which was significantly higher than their scores (3.39 ± 1.57 and 2.58 ± 1.38) in the podophyllin group (P = 0.00). CONCLUSION: Ingenol mebutate 0.05% gel is effective as podophyllin 25% solution in treating AGWs, with further benefit of being much more rapid. However, high recurrence rate, sever pain, and LSR limit its use.

Real-life treatment of cutaneous warts with cantharidin podophyllin salicylic acid solution.

Patients often request treatment of their burdensome cutaneous warts. However, a safe and effective treatment for cutaneous warts is lacking. This study evaluates treatment outcome, side effects, and patient satisfaction after topical application of cantharidin 1% podophyllin 2% salicylic acid 30% (CPS1) solution in a large series of children and adults with cutaneous warts. Fifty-two children and 83 adults with warts, treated with CPS1 solution between October 2012 and October 2014, were included. Complete clearance of warts occurred in 86.5% of children and 62.7% of adults treated with CPS1 solution (p < .01). Resolution of warts was partial in 3.9 and 24.1% and absent in 9.6 and 13.2% of children and adults respectively. Side effects were present in 41.2% of children and 46.3% of adults (p = .7). Most common side effects were blistering, pain, and burning sensation. No serious adverse events occurred. On a 10-point scale, median patient satisfaction score was 9.0 (interquartile range 7.8-10.0) and 8.0 (interquartile range 5.1-9.7) for children and adults respectively (p < .01). CPS1 solution is a safe and promising treatment modality with a high clearance and high patient satisfaction rate for the management of cutaneous warts, particularly in children.

Podophyllin Toxicity with Systemic Manifestations in a Young Male.

Podophyllin poisoning is a rare but a fatal poisoning with a long term systemic and neurological sequela. There has been no case report reported in an adult in India. We present a 28-year-old young male with podophyllin poisoning. This report confirms the transient central neurotoxicity of podophyllin and persistent peripheral neurotoxicity of podophyllin.

A novel anti-cancer role of ß-apopicropodophyllin against non-small cell lung cancer cells.

We previously reported that podophyllotoxin acetate (PA) inhibits the growth and proliferation of non-small cell lung cancer (NSCLC) cells and also makes them more sensitive to radiation and chemotherapeutic agents. In an attempt to enhance PA activity, we synthesized 34 derivatives based on podophyllotoxin (PPT). Screening of the derivative compounds for anti-cancer activity against NSCLC led to the identification of ß-apopicropodophyllin (APP) as a strong anti-cancer agent. In addition to its role as an immunosuppressive regulator of the T-cell mediated immune response, the compound additionally showed anti-cancer activity against A549, NCI-H1299 and NCI-460 cell lines with IC50 values of 16.9, 13.1 and 17.1 nM, respectively. The intracellular mechanisms underlying the effects of APP were additionally examined. APP treatment caused disruption of microtubule polymerization and DNA damage, which led to cell cycle arrest, as evident from accumulation of phospho-CHK2, p21, and phospho-Cdc2. Moreover, APP stimulated the pro-apoptotic ER stress signaling pathway, indicated by elevated levels of BiP, phospho-PERK, phospho-eIF2α, CHOP and ATF4. We further observed activation of caspase-3, -8 and -9, providing evidence that both intrinsic and extrinsic apoptotic pathways were triggered. In vivo, APP inhibited tumor growth of NSCLC xenografts in nude mice by promoting apoptosis. Our results collectively support a novel role of APP as an anticancer agent that evokes apoptosis by inducing microtubule disruption, DNA damage, cell cycle arrest and ER stress.

HOTAIR-mediated reciprocal regulation of EZH2 and DNMT1 contribute to polyphyllin I-inhibited growth of castration-resistant prostate cancer cells in vitro and in vivo.

BACKGROUND: Polyphyllin I (PPI), one of the steroidal saponins in paris polyphylla, has been reported to exhibit antitumor effects. However, the detailed molecular mechanism underlying this has not been elucidated. METHODS: Cell viability and cell cycle distribution were measured using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and Flow cytometry assays, respectively. Cell invasion and migration were examined by Transwell invasion and wound healing assays. Western blot analysis was performed to examine the protein expressions of zeste homolog 2 (EZH2), DNA methyltransferase 1 (DNMT1). QRT-PCR was used to examine the levels of long non-coding RNA (lncRNA) HOX transcript antisense RNA (HOTAIR). Small interfering RNAs (siRNAs) method was used to knockdown HOTAIR. Exogenously expressions of HOTAIR, DNMT1 and EZH2 were carried out by Transient transfection assays. EZH2 promoter activity was measured by Secrete-Pair Dual Luminescence Assay Kit. A nude mice xenograft model was used to confirm the findings in vitro. RESULTS: We showed that PPI significantly inhibited growth, induced cell cycle arrest of castration-resistant prostate cancer (CRPC) cells. In addition, PPI also reduced the migration and invasion in CRPC cells. In mechanism, we found that PPI decreased the protein expressions of EZH2, DNMT1 and levels of HOTAIR. Interestingly, silenced HOTAIR reduced EZH2 and DNMT1 protein expressions. On the contrary, exogenously expressed HOTAIR resisted PPI-inhibited EZH2 and DNMT1 protein expressions, EZH2 promoter activity and cell growth. Moreover, excessive EZH2 antagonized PPI-suppressed DNMT1 protein expression or vice versa. Consistent with this, PPI inhibited tumor growth, HOTAIR, the protein expressions of DNMT1 and EZH2 in vivo. CONCLUSION: Our results show that PPI inhibits growth of CRPC cells through inhibition of HOTAIR expression, subsequently; this results in the repression of DNMT1 and EZH2 expressions. The interactions among HOTAIR, DNMT1 and EZH2, and reciprocal regulation of DNMT1 and EZH2 contribute to the overall responses of PPI. This study reveals a novel mechanism for HOTAIR-mediated regulating DNMT1 and EZH2 in response to PPI in inhibition of the growth of CRPC cells.

Concise Synthesis of (+)-ß- and γ-Apopicropodophyllins, and Dehydrodesoxypodophyllotoxin.

Herein, we present an expeditous synthesis of bioactive aryldihydronaphthalene lignans (+)-ß- and γ-apopicropodophyllins, and arylnaphthalene lignan dehydrodesoxypodophyllotoxin. The key reaction is regiocontrolled oxidations of stereodivergent aryltetralin lactones, which were easily accessed from a nickel-catalyzed reductive cascade approach developed in our group.

Total Synthesis of the Claimed Structure of (±)-Hyptinin and Structural Revision of Natural Hyptinin.

A total synthesis of (±)-hyptinin was achieved via a convergent route using the key phosphonate, cyclic ketone, and aryl Grignard components. The 1H and 13C NMR spectra of natural hyptinin did not agree with those of the synthesized compound. In particular, there were considerable differences between the signals assigned to the protons and carbons surrounding the lactone carbonyl group for the natural and synthesized compounds. The NMR data strongly suggested that the naturally occurring compound, hyptinin, was a structural isomer of the synthesized compound. The structure of the natural compound was eventually established as (+)-ß-apopicropodophyllin, based on the synthesis results.

Imiquimod for anogenital warts in non-immunocompromised adults.

BACKGROUND: 30% of people with anogenital warts (AGW) have spontaneous regression of lesions but there is no way to determine whether a specific lesion will remain. There are a wide range of options available for treating people with AGW and selection is based on clinician's experience, patient preferences and adverse effects. The imiquimod could offer the advantages of patient-applied therapies without incurring the limitations of provider-administered treatments. OBJECTIVES: To assess the effectiveness and safety of imiquimod for the treatment of AGW in non-immunocompromised adults. SEARCH METHODS: We searched the Cochrane Sexually Transmitted Infections Group Specialized Register (15 April 2014), CENTRAL (1991 to 15 April 2014), MEDLINE (1946 to 15 April 2014), EMBASE (1947 to 15 April 2014), LILACS (1982 to 15 April 2014), World Health Organization International Clinical Trials Registry (ICTRP) (15 April 2014), ClinicalTrials.gov (15 April 2014), Web of Science (2001 to 15 April 2014) and OpenGrey (15 April 2014). We also handsearched conference proceedings, contacted trial authors and reviewed the reference lists of retrieved studies. SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing the use of imiquimod with placebo, any other patient-applied or any other provider-administered treatment (excluding interferon and 5-fluorouracil which are assessed in other Cochrane Reviews) for the treatment of AGW in non-immunocompromised adults. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trials for inclusion, extracted data and assessed risk of bias. We resolved any disagreements through consensus. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS: Ten RCTs (1734 participants) met our inclusion criteria of which six were funded by industry. We judged the risk of bias of the included trials as high. Six trials (1294 participants) compared the use of imiquimod versus placebo. There was very low quality evidence that imiquimod was superior to placebo in achieving complete and partial regression (RR 4.03, 95% CI 2.03 to 7.99; RR 2.56, 95% CI 2.05 to 3.20, respectively). When compared with placebo, the effects of imiquimod on recurrence (RR 2.76, 95% CI 0.70 to 10.91), appearance of new warts (RR 0.76, 95% CI 0.58 to 1.00) and frequency of systemic adverse reactions (RR 0.91, 95% CI 0.63 to 1.32) were imprecise. We downgraded the quality of evidence to low or very low. There was low quality evidence that imiquimod led to more local adverse reactions (RR 1.73, 95% CI 1.18 to 2.53) and pain (RR 11.84, 95% CI 3.36 to 41.63).Two trials (105 participants) compared the use of imiquimod versus any other patient-applied treatment (podophyllotoxin and podophyllin). The estimated effects of imiquimod on complete regression (RR 1.09, 95% CI 0.80 to 1.48), partial regression (RR 0.77, 95% CI 0.40 to 1.47), recurrence (RR 0.49, 95% CI 0.21 to 1.11) or the presence of local adverse reactions (RR 1.24, 95% CI 1.00 to 1.54) were imprecise (very low quality evidence). There was low quality evidence that systemic adverse reactions were less frequent with imiquimod (RR 0.30, 95% CI 0.09 to 0.98).Finally, two trials (335 participants) compared imiquimod with any other provider-administered treatment (ablative methods and cryotherapy). There was very low quality of evidence that imiquimod did not have a lower frequency of complete regression (RR 0.84, 95% CI 0.56 to 1.28). There was very low quality evidence that imiquimod led to a lower rate of recurrence during six-month follow-up (RR 0.24, 95% CI 0.10 to 0.56) but this did not translate in to a lower recurrence from six to 12 months (RR 0.71, 95% CI 0.40 to 1.25; very low quality evidence). There was very low quality evidence that imiquimod was associated with less pain (RR 0.30, 95% CI 0.17 to 0.54) and fewer local reactions (RR 0.55, 95% CI 0.40 to 0.74). AUTHORS' CONCLUSIONS: The benefits and harms of imiquimod compared with placebo should be regarded with caution due to the risk of bias, imprecision and inconsistency for many of the outcomes we assessed in this Cochrane Review. The evidence for many of the outcomes that show imiquimod and patient-applied treatment (podophyllotoxin or podophyllin) confer similar benefits but fewer systematic reactions with the Imiquimod, is of low or very low quality. The quality of evidence for the outcomes assessing imiquimod and other provider-administered treatment were of very low quality.

Efficacy of combination therapy of oral zinc sulfate with imiquimod, podophyllin or cryotherapy in the treatment of vulvar warts.

AIM: Zinc sulfate is beneficial in the treatment of epithelial warts. We conducted this study to compare the efficacy of combination therapy of oral zinc sulfate with conventional treatments in the treatment of vulvar warts. MATERIAL AND METHODS: This study was a randomized controlled trial. The sample size was 42 in each group. Women aged 20-50 years were placed by the block randomized method into six groups: the podophyllin-, imiquimod- and cryotherapy-treated groups, and another three groups receiving 8-week combination therapy of 400 mg oral zinc sulfate with one of the above-mentioned treatments. Data were analyzed using anova and Fischer's exact test with spss16. RESULTS: A total of 228 patients were recruited and completed the study in six treatment groups. No significant difference was observed in the response to treatment among these groups. Relapse after 6 months was significantly higher in the podophyllin-, imiquimod- and cryotherapy-treated patients compared to patients receiving these treatments in combination with oral zinc sulfate (P<0.05). CONCLUSIONS: Combined therapy of oral zinc sulfate with conventional treatments of vulvar warts appears to reduce the relapse rate.

Successful combination therapy of trichloroacetic acid, podophyllin, and electrocautery on giant condylomata acuminata.

Introduction: Giant condylomata acuminata (GCA) is a rare presentation of anogenital wart (AGW), invasive locally but does not metastasize. Combination therapy for GCA is suggested based on modalities and experiences. The combination of TCA and podophyllin has showed good efficacy, followed by electrocautery to eradicate warts. Case: A 24-year-old male had a chief complaint of large warts on the base of the penis that had started to bleed for 4 weeks. The initial lesion appeared 8 months prior as a small varucose papule. The patient is unmarried and has history of sexual contact with sex workers. Physical examination showed multiple verrucous papules, flesh-coloured, cauliflower-like shaped, 5 × 2 × 1 cm in size. The patient tested negative for HIV infection. Histopathological examination showed acanthosis, exophytic growth, parakeratosis, and koilocytosis with no signs of malignancy. This patient received a combination of TCA 90% and podophyllin 25% to initially reduce the tumor size, followed by electrocautery to eradicate the remaining lesions. The tumor showed complete clearance. Discussion: There is no definitive evidence that one therapy is superior to completely eliminating warts. Combination therapy of TCA and podophyllin leads to complete wart clearance, followed by electrocautery to destroy smaller warts.

Identification of Epstein-Barr virus after topical treatment for oral hairy leukoplakia: A preliminary study.

BACKGROUND: This study evaluated the presence of Epstein-Barr virus type 1 (EBV-1) DNA in patients living with HIV, before and after three different topical therapy protocols for oral hairy leukoplakia (OHL). METHODS: The sample consisted of five patients treated with topical solution of 25% podophyllin resin; six with 25% podophyllin resin plus 5% acyclovir cream; and four with 25% podophyllin resin plus 1% penciclovir cream. DNA was extracted from OHL scrapings and amplified by the PCR using specific primers for EBV-1 (EBNA-1). RESULTS: Clinical healing of OHL lesions was observed across all treatment groups over time. At baseline, EBNA-1 was detected in all OHL lesions. After treatment, OHL samples from three patients treated with 25% podophyllin resin plus 5% acyclovir cream and from one patient treated with 25% podophyllin resin plus 1% penciclovir cream exhibited negative EBNA-1 viral gene encoding. Despite the clinical resolution of OHL, 11 patients (73.3%) showed EBNA-1 positivity immediately after the lesion disappeared. Three patients (20%) treated with podophyllin resin displayed both EBNA-1 positivity and a recurrence of OHL, in contrast to no recurrence in the other two groups. CONCLUSIONS: These findings suggest potential associations between treatment formulations, EBNA-1 persistence, and the recurrence of OHL lesions.

Effectiveness and safety of topical application of diphenylcyclopropenone versus podophyllin in treatment of genital warts.

BACKGROUND: Many therapeutic modalities are available for treating genital warts; however, the effectiveness of both diphenylcyclopropenone and podophyllin is still controversial. AIM: To evaluate the effectiveness and safety of diphenylcyclopropenone and podophyllin in treating genital warts. METHODS: This study included 57 patients, divided randomly into two groups. Group (A): diphenylcyclopropenone (n = 29). Group (B): podophyllin 25% (n = 28). In group (A), sensitization was done with 2% diphenylcyclopropenone. Then, after 1 or 2 weeks, treatment started with a weekly application of diphenylcyclopropenone solutions ranging between 0.001 and 1% until clearance, or for a maximum of 10 sessions. In group (B), podophyllin 25% was applied weekly until clearance or for a maximum of 6 weeks. RESULTS: Higher clearance was achieved in group A, with 19 of 29 (65.5%) patients, than in group B, with 9 of 28 (32.1%) (p-value = 0.004). Also, effectiveness increases with young age in group A. Shorter wart duration was associated with better response in both groups (p-value = 0.005). No serious adverse effects occurred in either group. No recurrence was detected in group A, while seven patients (77.8%) had recurrence in group B after 1 year of follow up. CONCLUSION: Diphenylcyclopropenone shows a higher success rate than podophyllin in treating genital warts and a lower recurrence rate.

Trends of genital wart in Korea according to treatment method classification: Big data analysis of health care in 2010-2019.

PURPOSE: The purpose of this study is to investigate disease trend of genital wart through changes in each treatment method over the past 10 years in Korea. MATERIALS AND METHODS: From 2010 to 2019, surgical treatment including cauterization, excision, cryotherapy, and laser therapy, non-surgical treatment such as podophyllin, and surgical treatment for anorectal lesion were extracted and analyzed from 2010 to 2019. For each treatment method, characteristics such as sex, age, region, medical cost and average number of procedures were analyzed. RESULTS: The number of patients following all treatment modalities increased every year. Surgical treatment of genital wart and anorectal wart showed a significant increase in male patients. Number of non-surgical treatment decreased in males but increased in females. Surgical removal of the anorectal wart increased more than 250% in over 10 years, and males underwent surgery 4 times more than females. In both surgery and non-surgery, the mean session was higher in males. Most of them were carried out in primary medical institutions. In Seoul and Gyeonggi-do, the largest number of patients received treatment regardless of treatment method. CONCLUSIONS: Treatment for genital warts has increased rapidly over the past 10 years, and the increase in males is remarkable. The main treatment was surgery, and males mainly received surgical treatment, and females mainly received drug treatment. The primary medical institution was in charge of the most treatment. As the number of patients and related medical expenses are increasing rapidly, more attention and response to diseases are needed.

Xeroderma Pigmentosum: Part Two: Treatment of Skin Tumors with Topical Podophyllin 25% in Benzoin.

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease; relatively mild XP patients are sometimes designated as having pigmented xerodermoid or xerodermoid pigmentosum (XP-V), a variant of XP. It is commonly associated with many long-standing skin conditions and tumors, including malignancies, management of which is necessary to prevent the progress of the disease. The objective of the study was to evaluate an innovative therapeutic treatment, beyond surgery, surgical excision, cryotherapy, electrocautery and curettage, or Mohs surgery, for the management of skin tumors in XP.This was a prospective therapeutic interventional study comprising 50 patients with XP-V. Age of subjects ranged from 2 to 50 years, with a mean age of 18 years. Several measures were evaluated in part one of this study, and a number of others (as reviewed in part one) were successful in prophylaxis of skin tumors in XP as well as in treating earlier stigmata of XP; however, these measures were notably less successful in treating well-developed skin tumors in XP patients, and 18 of the 50 patients evaluated in part one had well-developed tumors (total 22 lesions) refractory to treatments. Podophyllin 25% in 100-mL tincture of benzoin was applied topically to lesions until complete resolution was documented in 18 patients with XP complications, such as keratoacanthoma (KA), basal cell carcinoma, or squamous cell carcinoma. Topical podophyllin 25% in benzoin was a less destructive alternative treatment for skin cancer and KA in XP patients.
