Smoking enhances risk for new external genital warts in men

Association of tobacco use and the presence of anal warts in people who attend the anal Neoplasia clinic in Puerto Rico

Background

Limited research exists regarding the association between smoking and anal warts. In this study, we evaluated this association among a clinic-based Hispanic population in Puerto Rico.

Methods

Cross-sectional study among eligible patients seen at the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center (2016-2023) (n = 920). Sociodemographic and clinical variables were collected from medical records. Patients underwent a high-resolution anoscopy (HRA) during the clinical visit; physicians assessed anal condylomas on HRA. Poisson regression models with robust standard errors were used to evaluate the association between smoking and anal warts. Demographic and clinical factors were also assessed.

Results

The mean age of participants was 45.8 ± 13.1 years, 66.4 % were men, and 21.6 % were current smokers. While 10.8 % self-reported a history of anogenital condylomas, 18.9 % had anal condylomas on clinical evaluation. A higher prevalence of anal condylomas was observed among current smokers (PR = 1.28, 95 % CI: 0.94-1.75) in comparison to non-smokers in adjusted analysis, but this was not statistically significant. However, a higher prevalence of anal condylomas was observed among younger individuals (PR = 0.96, 95 % CI: 0.96-0.98) and individuals with anal high-grade squamous intraepithelial lesions (HSIL) as compared to those with benign histology (PR = 1.74. 95 % CI: 1.09-2.77).

Conclusions

Although current smoking seemed to be positively associated with anal condylomas in this high-risk Hispanic population, this finding was not statistically significant as the power to detect an association was limited. However, younger age and HSIL diagnosis were associated with a higher prevalence of anal condylomas.

Condyloma acuminatum of the urinary bladder with underlying squamous cell carcinoma: a case report

BACKGROUND

Condyloma acuminatum is a rare finding of the urinary bladder. There are many morphological variants that exist. It has been previously reported that some of these variants were found to be associated with subsequent or concurrent squamous cell carcinoma. However, there are limited cases that describe this underlying malignancy found in patients with bladder condyloma.

CASE PRESENTATION

A 38-year-old African American female presented with condyloma acuminatum of the urinary bladder and underlying squamous cell carcinoma, which also invaded the neighboring uterus, urethra, and anterior vagina. Initial attempts at treatment began with cystoscopic resection of the condyloma; however, due to diffuse transformation, we pursued radical cystectomy with adjuvant chemotherapy and radiation.

CONCLUSION

As such a finding is rare in the urinary bladder, with few reports discussing its association with ensuing squamous cell carcinoma, we hope that this continues to generate awareness and consideration in the treatment of affected individuals.

The Impact of Closeness to Non-Parental Adults in Social Networks on Substance Use among Young Men Who Have Sex with Men

Non-parental adults (NPAs), or adults in social networks other than parents and romantic/sexual partnersare an under-examined potential resource in the lives of young men who have sex with men (YMSM). Using survey and social network data from a sample (n = 169) of ethnically diverse YMSM in a Midwestern city, this article examines longitudinal associations between emotional closeness to NPAs and subsequent substance use among YMSM. After controlling for race/ethnicity, closer relationships with NPAs were associated with a lower likelihood of binge-drinking and marijuana use six months later. In an exploratory set of analyses, the level of connectedness between NPAs and other members of social networks was not associated with substance use. Future studies should continue to examine the protective role of NPAs for both substance use and other health behaviors among YMSM.

Holistic dermatology: An evidence-based review of modifiable lifestyle factor associations with dermatologic disorders

BACKGROUND

Holistic dermatology focuses on treating the human body as a whole and implementing lifestyle changes to enhance the treatment and prognosis of skin disease. Understanding the interplay between modifiable lifestyle factors and patients' dermatologic health will help physicians better inform patients on self-care methods to mitigate the burden of their skin disease(s).

OBJECTIVE

To review the current scientific literature on the relationship between modifiable lifestyle factors and the dermatologic outcome of skin disorders.

METHODS

A systematic literature search on PubMed, Cochrane, and Web of Science was conducted to identify research articles examining the relationship between dermatology and 6 major categories of modifiable lifestyle factors: diet, sleep, exercise, stress, alcohol, and smoking.

RESULTS

A substantial amount of evidence supports the relationship between modifiable lifestyle factors and dermatologic outcomes. There were the most studies on diet, stress, alcohol, and smoking, but all lifestyle factors were supported by some degree of scientific evidence.

CONCLUSION

All modifiable lifestyle factors explored in this review play a critical role in modulating the onset and progression of skin disease. We anticipate more research studies in the future and an increasing integration of holistic dermatology into patient care.

Smoking: Is it a Risk Factor for Common Warts?

INTRODUCTION

Common warts are one of the most prevalent infections affecting the skin. Common warts are caused by human papillomaviruses (HPV), which are ubiquitous in our environment. Most HPV infections are directly controlled and cleared by host immune system, although each case has the potential to persist and transform into a recalcitrant form. It is not exactly clear why certain populations are more susceptible to common warts.

AIM

To investigate factors affecting the occurence and outcome of common warts.

MATERIAL AND METHODS

A total of 188 consecutive patients with common warts (106 men, 82 women) and 188 controls were prospectively enrolled. Demographic and clinical characteristics were recorded. The Chi-square, Mann-Whitney U and Kruskal-Wallis tests were used for statistical analysis, with a significance threshold of p<0.05.

RESULTS

There were not any significant associations between cigarette smoking, alcohol consumption, accompanying diseases, medications, family history of warts and the duration of warts (p=0.102, p=0.317, p=0.535, p=0.535, p=0.535, respectively). There were not any significant associations between cigarette smoking, alcohol consumption, accompanying diseases, medications, family history of warts and the number of warts (p=0.232, p=0.762, p=0.389, p=0.389, p=0.824, respectively).

CONCLUSIONS

Our study has revealed that smoking is not a risk factor for common warts. However, we suspect the lack of statistical differences are likely due to small sample size of the study. Further studies with larger sample sizes are needed.

Self-reported genital warts among sexually-active university students: a cross-sectional study

BACKGROUND

Genital warts are one of the most common forms of sexually-transmitted disease, but their epidemiology has yet to be thoroughly elucidated. The present study was designed to shed light on the prevalence of clinically-confirmed, self-reported genital warts (GWs) in a representative sample of the university population.

METHODS

In 2015, a cross-sectional survey was conducted on 11,096 individuals approached at the Students Information Bureau where they came to enroll for a university degree course. Participants completed an anonymous, self-administered questionnaire providing information on their sociodemographic characteristics, sexual behavior, and any history of clinically-diagnosed genital warts. Multivariate logistic regression was then used to identify any factors associated with the disease.

RESULTS

Our analysis was conducted on 9259 questionnaires (83.4%). Participants were a mean 21.8 ± 4.8 years of age, and 59.6% were female. Overall, 124 individuals (1.3%, 95%CI: 1.0-1.6) reported having been diagnosed with genital warts: 48 men (1.3%, 95%CI: 0.9-1.6), and 76 women (1.4% 95%CI: 1.1-1.7). Overall, 22.5% of the sample were vaccinated (1.3% of the males and 36.8% of the females). The group of respondents aged 30 years or more had the highest incidence of genital warts (males: 5.6%, 95%CI: 2.5-8.6; females: 6.9%, 95%CI: 3.4-10.4). The independent risk factors associated with a history of disease were (for both genders) a history of other sexually-transmitted diseases, and ≥2 sex partners in the previous 24 months. A protective role emerged for routine condom use. Additional risk factors associated with genital warts in males concerned men who have sex with men, bisexuality vis-à-vis heterosexuality, and smoking.

CONCLUSIONS

The findings emerging from our study help to further clarify the epidemiology of genital warts in young people, and may be useful to public health decision-makers. This study showed that genital warts occur in men as well as women, and suggests that both genders should be monitored for this disease to ascertain the effects of the free HPV vaccination offered to all girls in the Veneto in their 12th year of life since 2008, and to all boys of the same age since 2015.

Human Papillomavirus in Thai Women and Men with Anogenital Warts

<b><i>Objective:</i></b> Anogenital warts are caused by human papillomavirus (HPV). Globally, HPV genotypes 6 and 11 are most often associated with anogenital warts. However, the diversity of HPV genotypes found in patients with genital warts in Thailand is unknown. The aim of this study was to investigate HPV-associated anogenital warts in the Thai population and to assess whether genotypes found are represented in the bivalent and quadrivalent HPV vaccine. <b><i>Methods:</i></b> This study included 206 anogenital swab samples from patients who were diagnosed with anogenital warts. Detection of HPV DNA was performed using polymerase chain reaction to amplify the L1 gene and sequencing.<b><i> Results:</i></b> HPV was identified in 88.3% (182/206) of the samples. The majority of HPV genotypes were low-risk genotypes HPV6 (36.9%) and HPV11 (36.4%), which represented the most common infection found in genital warts in this study. <b><i>Conclusion:</i></b> Immunization with the quadrivalent vaccine (HPV6, HPV11, HPV16, and HPV18) could potentially prevent genital warts caused by HPV infection.

2016 United Kingdom national guideline on the sexual health care of men who have sex with men

This guideline is intended for use in UK Genitourinary medicine clinics and sexual health services but is likely to be of relevance in all sexual health settings, including general practice and Contraception and Sexual Health (CASH) services, where men who have sex with men (MSM) seek sexual health care or where addressing the sexual health needs of MSM may have public health benefits. For the purposes of this document, MSM includes all gay, bisexual and all other males who have sex with other males and both cis and trans men. This document does not provide guidance on the treatment of particular conditions where this is covered in other British Association for Sexual Health and HIV (BASHH) Guidelines but outlines best practice in multiple aspects of the sexual health care of MSM. Where prevention of sexually transmitted infections including HIV can be addressed as an integral part of clinical care, this is consistent with the concept of combination prevention and is included. The document is designed primarily to provide guidance on the direct clinical care of MSM but also makes reference to the design and delivery of services with the aim of supporting clinicians and commissioners in providing effective services. Methodology This document was produced in accordance with the guidance set out in the BASHH CEG's document 'Framework for guideline development and assessment' published in 2010 at http://www.bashh.org/guidelines and with reference to the Agree II instrument. Following the production of the updated framework in April 2015, the GRADE system for assessing evidence was adopted and the draft recommendations were regraded. Search strategy (see also Appendix 1) Ovid Medline 1946 to December 2014, Medline daily update, Embase 1974 to December 2014, Pubmed NeLH Guidelines Database, Cochrane library from 2000 to December 2014. Search language English only. The search for Section 3 was conducted on PubMed to December 2014. Priority was given to peer-reviewed papers published in scientific journals, although for many issues evidence includes conference abstracts listed on the Embase database. In addition, for 'Identification of problematic recreational drug and alcohol use' section and 'Sexual problems and dysfunctions in MSM' section, searches included PsycINFO. Methods Article titles and abstracts were reviewed and if relevant the full text article was obtained. Priority was given to randomised controlled trial and systematic review evidence, and recommendations made and graded on the basis of best available evidence. Piloting and feedback The first draft of the guideline was circulated to the writing group and to a small group of relevant experts, third sector partners and patient representatives who were invited to comment on the whole document and specifically on particular sections. The revised draft was reviewed by the CEG and then reviewed by the BASHH patient/public panel and posted on the BASHH website for public consultation. The final draft was piloted before publication. Guideline update The guidelines will be reviewed and revised in five years' time, 2022.

Relationship between human papillomavirus and penile cancer-implications for prevention and treatment

Penile cancer is a rare disease in the United States, but rates are increasing, causing concern. Several risk factors have been associated with the disease, including human papillomavirus (HPV) infection. Knowledge of HPV pathogenesis has led to the development of a vaccine, which has proven instrumental in reducing the incidence of female HPV-related cancers, but results in men have yet to be elucidated. Fortunately, rates of vaccination are up-trending in both males and females in the past several years. In addition, targeted therapies are the focus of several ongoing research efforts. Some of these therapeutics are currently in use, while several are in trials. With continued patient education and research, both treatment and prevention of HPV-related pre-malignant lesions and penile cancer will likely diminish.

Demographic characteristics and risk factors in Turkish patients with anogenital warts

Anogenital warts (AGW) are one of the most common sexually transmitted diseases worldwide. The determination of groups vulnerable to contracting anogenital warts (AGW) leads to the development of policies for disease control and of prevention programs. The aim of our study was to investigate the demographical features and risk factors of Turkish patients with AGW. This study included 200 patients with AGW and 200 healthy individuals as a control group. The age, gender, education and marital status, age of first sexual intercourse, number of sexual partners, sexual orientation, and smoking status were recorded in both groups. In this study, 88% of the patients were male, and 12% were female. The mean age of the patients was 35.21±0.77 years, and the majority of patients were below 35 years old (63%). Furthermore, 46.0% of the patients were educated at the university level, and 33.5% had graduated high school. No significant differences were found based on sexual orientation or condoms between the patient and control groups. In the patient group, the mean age of first sexual intercourse was significantly earlier, and the number of single individuals and sexual partners were significantly higher. Also, 61% of the patients were current smokers, which was significantly higher than the control group. The duration of smoking and the duration of AGW were found to be correlated. All patients were tested for anti-HIV antibodies, and only one patient was found to be infected. AGW were more common in patients younger than 35 years old, among men, and among those who had graduated from high school or university. Early age of first sexual intercourse, a high number of sexual partners, being single, and smoking were also risk factors for the development of anogenital warts.

Combined treatment of anogenital HPV infection with cryodestruction, podophyllin 25% and post-ablation immunomodulation with sinecatechins 15% ointment - a retrospective analysis

External genital warts, caused by human papillomavirus, have a significant clinical, epidemiological, and financial impact, including the risk for malignant transformation. Treatment modalities include: (a) destructive (ablative); (b) cytotoxic (proapoptotic) and (c) immunomodulatory, with success and recurrence rates varying from 23% to 94% and from 4.1% to 77%, respectively. Most studies evaluated only single modality therapy, with few reports examining a combined approach for external genital warts management. The introduction of sinecatechins ointment in recent years has resulted in very low recurrence rates of 4.1-10.6%, despite lower initial clearance rates than ablative methods. We present a retrospective review of 27 patients who underwent combined therapy for external genital warts by using one or two sessions of cryodestruction combined with 25% podophyllin as the cytotoxic agent, and post-ablation immunomodulation with topical sinecatechins 15% ointment. This approach resulted in an excellent initial clearance rate of 96.3% with a recurrence rate of 7.4% after a total period of six months of follow-up. We suggest the importance of the combined approach in external genital warts management including post-ablative immunomodulation to augment the immune response and combat the residual latent infection. We hope to encourage trials examining the combined approach to the treatment of external genital warts.

HIV-1 infection, but not syphilis or HBV infection, is a strong risk factor for anorectal condyloma in Asian population: a prospective colonoscopy screening study

OBJECTIVE

To investigate the association between anorectal precancerous lesions, including condyloma, and sexually transmitted infections (STI) in Asian population.

METHODS

This prospective study enrolled 2677 patients who underwent high-resolution colonoscopy for anorectal cancer screening. Anorectal lesions were diagnosed based on endoscopic findings and confirmed by biopsy. The association of HIV-1 infection, syphilis, and HBV infection with anorectal lesion was estimated by multivariate logistic regression. In HIV-1-infected patients (n=244), anal canal HPV-DNA was screened and genotyped.

RESULTS

Although no malignancy was identified, anorectal condyloma was diagnosed in 32 (1.2%) male patients. 41% of anorectal condyloma cases had no specific lower GI symptoms. Multivariate analysis identified HIV-1 infection, but not syphilis or HBV infection, as an independent significant factor for condyloma (OR: 176.5, 95%CI 22.52-1383, p<0.001). In HIV-1 infected patients, positive type 16/18 HPV-DNA (OR: 4.766, 95%CI 1.838-12.36, p=0.001), lower CD4 cell count (per 100/μl decrement, OR: 1.056, 95%CI 1.056-1.587, p=0.013), and current smoking (OR: 3.828, 95%CI 1.486-9.857, p=0.005) were independently associated with anorectal condyloma.

CONCLUSIONS

HIV-1 infection, but not syphilis or HBV infection, was identified as a strong risk for anorectal condyloma. Anal HPV 16/18 was highly prevalent in patients with HIV-1 infection, especially in those with condyloma.

Rates and predictors of genital warts burden in the Czech population

OBJECTIVE

To describe the burden and the predictors of genital warts (GWs) in Czech men and women.

METHODS

A population-based cross-sectional study was conducted of 32 974 randomly selected health clinic attendees from all 14 regions of the Czech Republic. Information on GWs and lifestyle behaviour was collected using a questionnaire.

RESULTS

Results revealed a 5.8% prevalence rate of self-reported GWs in the Czech population aged 16-55 years. There was an increase in the incidence of GWs in the years 2010-2013 when compared to lifetime incidence rates, from 205.4 (95% confidence interval (CI) 191.0-219.7) to 441.8 (95% CI 393.1-490.6) per 100 000 person-years. No significant differences were observed between genders. The strongest risk factors found for GWs were an infected sexual partner (adjusted odds ratio (OR) 114.3, 95% CI 78.9-165.4) and a high number of lifetime sexual partners (adjusted OR 3.36, 95% CI 2.72-4.17 for >14 partners vs. one partner). A novel finding was that 22.7% (95% CI 20.9-24.6%) of participants claimed that the pathology had disappeared spontaneously without medical assistance.

CONCLUSIONS

The results provide baseline information for the development and monitoring of prevention strategies against GWs in the Czech Republic.

The impact of smoking on HPV infection and the development of anogenital warts

PURPOSE

The worldwide prevalence of human papillomavirus (HPV) infection is estimated at 9-13 %. Persistent infection can lead to the development of malignant and nonmalignant diseases. Low-risk HPV types are mostly associated with benign lesions such as anogenital warts. In the present systematic review, we examined the impact of smoking on HPV infection and the development of anogenital warts, respectively.

METHODS

A systematic literature search was performed using MEDLINE database for peer-reviewed articles published from January 01, 1985 to November 30, 2013. Pooled rates of HPV prevalence were compared using the χ (2) test.

RESULTS

In both genders, smoking is associated with higher incidence and prevalence rates for HPV infection, whereas the latter responds to a dose-effect relationship. The overall HPV prevalence for smoking patients was 48.2 versus 37. 5 % for nonsmoking patients (p < 0.001) (odds ratio (OR) = 1.5, 95 % confidence interval (CI) 1.4-1.7). Smoking does also increase persistence rates for high-risk HPV infection, while this correlation is debatable for low-risk HPV. The incidence and recurrence rates of anogenital warts are significantly increased in smokers.

CONCLUSIONS

Most current data demonstrate an association between smoking, increased anogenital HPV infection, and development of anogenital warts. These data add to the long list of reasons for making smoking cessation a keystone of patient health.

Association between smoking and size of anal warts in HIV-infected women

While the association between smoking and human papillomavirus infection, cervical cancer, and anal cancer has been well studied, evidence on the association between cigarette smoking and anal warts is limited. The purpose of this study was to investigate if cigarette smoking status influences the size of anal warts over time in HIV-infected women in a sample of 976 HIV-infected women from the Women's Interagency HIV Study (WIHS). A linear mixed model was used to determine the effect of smoking on anal wart size. Even though women who were currently smokers had larger anal warts at baseline and slower growth rate of anal wart size after each visit than women who were not current smokers, there was no association between size of anal wart and current smoking status over time. Further studies on the role of smoking and interaction between smoking and other risk factors, however, should be explored.

Smoking and the skin

Cigarette smoking has been associated with significant morbidity affecting all systems of the body, including the integumentary system. We review the many dermatologic hazards of tobacco use. It is important to distinguish between the effects of tobacco smoke from effects of pure nicotine on the skin. All skin cells express several subtypes of the nicotinic class of acetylcholine receptors, including the α7 receptor. Many chronic dermatoses are affected by smoking either negatively or positively. Elucidation of positive associations with a particular disease can lead to improvement from smoking cessation, whereas inverse correlation may lead to development of a disease-specific treatment with nicotinergic agonists.
