A study on the cognitive status of human papillomavirus among adult males in Tianjin based on the health belief model

Background:To understand the health beliefs and knowledge of human papillomavirus among adult males in Tianjin.Methods:An online questionnaire survey was conducted from 18 January 2023 to 6 March 2023 using snowball sampling method.Analyze the health belief scores and human papillomavirus(HPV)and HPV vaccine knowledge scores of adult males in Tianjin,and analyze their influencing factors.Results:A total of 388 adult males in Tianjin were surveyed,with an average total score of 3.23±0.04 for their health beliefs.Among them,the average scores for perceived severity,perceived susceptibility,perceived impairment,perceived benefit,and self-efficacy were 3.41±1.05,2.37±1.20,2.96±1.00,3.51±0.90,and 3.36±1.08,respectively.Multiple linear regression analyses showed education was a factor influencing health beliefs.The average total score of knowledge is 64.09±15.62,with 277 people scoring above 60,and a pass rate of 71.4%.Through multiple linear regression analysis,education level,emotional status,whether disease testing has been done,and whether family and friends have been diagnosed with HPV positive are the main influencing factors.Conclusion:The awareness rate of HPV among adult males in Tianjin is still acceptable,but there are still misconceptions.The overall level of health beliefs is moderate,and the perceived susceptibility level is low.It is necessary to strengthen health education on HPV related knowledge for males and improve their cognitive level.

Acute motor axonal neuropathy following anti-rabies human diploid cell vaccine:A rare case and review

Rationale:Guillain Barre syndrome(GBS)is an acute neurological illness leading to quadriparesis with respiratory involvement.It can be triggered by infections,vaccinations,surgery,trauma,transplantation and drugs.Anti-rabies cell culture vaccines introduced to overcome the high rate of neurological complications associated with tissue based rabies vaccine,can be very rarely associated with GBS.Patient concerns:A 50-year-old female presented with acute severe upper back pain evolving into pure motor quadriparesis following administration of human diploid cell vaccine for rabies.Diagnosis:Acute motor axonal neuropathy variant of GBS following anti-rabies human diploid cell vaccine.Interventions:Intravenous high dose steroids.Outcomes:Patient recovered completely within 1 month.Lessons:Although anti-rabies cell culture vaccines are highly immunogenic and safe,they are rarely associated with GBS.Clinicians should be aware of this link because prompt diagnosis and treatment can result in complete recovery and avoid complications.

Monoarthropathy or Polyarthritis in Adolescent Japanese Girls Who Received Immunization with the Human Papillomavirus Vaccine

Joint pain or arthralgia is a common complaint among girls who have received immunization with the human papillomavirus (HPV) vaccine, but the pathogenesis of this disorder has not been completely understood. We report 2 cases of joint lesions after HPV vaccination. In one case, a 13-year-old patient showed transient arthropathy in the right wrist joint after the first dose of Gardasil® administered in her left shoulder. In the other case, an 18-year-old patient had migrating joint pain with redness and swelling after the third dose of Cervarix®. Her serum C-reactive protein and anti-MMP-3 levels were slightly elevated, but no autoantibodies, including rheumatoid factor and anti-CCP antibody, were detected. Although various nonsteroidal anti-inflammatory drugs produced no relief, small doses of both tacrolimus and prednisolone were highly effective for her polyarthritis. The development of reactive joint lesions after HPV vaccination was noteworthy.

Studies on the correlation between human papilloma virus vaccine and premature ovarian failure

Cervical cancer is the most common malignant tumour of the female reproductive system,resulting in more than 500,000 new cases annually worldwide.In developing countries,cervical cancer ranks second in terms of cancer mortality among women.Human papilloma virus is the primary causative agent of cervical cancer,with approximately 70 percent of cervical cancers caused by high-risk types of human papilloma virus 16 and 18.There are currently three types of human papilloma virus vaccines available:bivalent,quadri-valent and nine-valent.However,in recent years,it is reported that cervical cancer vaccine can cause premature ovarian failure.Consequently,an extensive literature search to find out the correlation between human papilloma virus vaccine and premature ovarian failure became a priority.There is no sufficient evidence to support or prove that there is a link between the human papilloma virus vaccine and premature ovarian failure.Hence,the vaccine does not cause premature ovarian failure.

Cervical Cancer Prevention Challenges and Barriers to Cervical Cancer Screening and HPV Vaccinations in Ukraine and Eastern Europe

Objectives: To identify the obstacles and issues that hinder effective cancer prevention efforts in Ukraine. The study aims to provide a comprehensive assessment of the barriers to cancer prevention, including both infrastructure and behavioral factors, and identify potential solutions to address these challenges. Study Design: Comprehensive literature review. Methods: The following databases were searched: National Center for Biotechnology Information (NCBI) and PubMed (U.S. National Library of Medicine at the National Institutes of Health). The keywords used in the search included “Cervical Cancer”, “Human Papillomavirus Vaccination (HPV)”, “Ukraine”, “Eastern Europe”, “Healthcare Infrastructure in Disasters”, “Cervical Cancer Prevention”, “Pap Smear”, and “HPV Testing”. Results: A total of 3500 articles were screened. A total of 65 articles met the inclusion criteria. Limited public awareness and limited access to vaccination and screening, combined with inadequate treatment facilities lead to higher rates of cervical cancer. The COVID pandemic, war with Russia, and the Chernobyl disaster are significant factors for the low level of vaccination in Ukraine. Conclusion: The prevention and treatment of cervical cancer in Ukraine face significant challenges due to the inadequate HPV vaccination rates and screening by cytology. Efforts to improve funding and increase education of both the population and health care providers are necessary to increase interventions such as HPV vaccination, cervical cytology, and HPV testing to reduce cervical cancer rates in Ukraine.

Anal intraepithelial neoplasia: A review of diagnosis and management

Anal intraepithelial neoplasia(AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus(HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior. A history of HPVmediated genital cancer, which suggests infection with an oncogenic HPV strain, is another risk factor for AIN/anal cancer. Because progression of AIN to anal cancer is known to occur in some individuals over several years, screening for AIN and early anal cancer, as well as treatment of advanced AIN lesions, is reasonable in certain high-risk populations. Although randomized controlled trials evaluating screening and treatment outcomes are lacking, experts support routine screening for AIN in high risk populations. Screening is performed using anal cytological exams, similar to those performed in cervical cancer screening programs, along with direct tissue evaluation and biopsy via high resolution anoscopy. AIN can be treated using topical therapies such as imiquimod, 5-flurouracil, and trichloroacetic acid, as well as ablative therapies such as electrocautery and laser therapy. Reductions in AIN and anal cancer rates have been shown in studies where high-risk populations were vaccinated against the oncogenic strains of HPV. Currently, the CDC recommends both high-risk and average-risk populations be vaccinated against HPV infection using the quadrivalent or nonavalent vaccines. It is important for clinicians to be familiar with AIN and the role of HPV vaccination, particularly in high risk populations.

Sexually transmitted infections of the anus and rectum

Sexually transmitted infections(STIs) represent a significant public health concern.Several STIs,once thought to be on the verge of extinction,have recently reemerged.This change is thought to be partially related to an increase in STIs of the anus and rectum.Importantly,the global human immunodeficiency virus and acquired immunodeficiency syndrome(HIV/AIDS) epidemic has contributed to the emergence of particular anorectal lesions that require specialized approaches.In this report,we review common anorectal STIs that are frequently referred to colorectal surgeons in the United States.Epidemiology,clinical presentation,and management are summarized,including the latest treatment recommendations.The particularity of anorectal diseases in HIV/AIDS is addressed,along with recent trends in anal cytology and human papillomavirus vaccination.

Clinician Misperceptions about the Importance of Adolescent HPV Vaccination

Introduction: Adolescent HPV vaccination rates remain suboptimal. The purpose of the study was to investigate attitudes about HPV vaccine relative to other adolescent vaccines among clinical staff from primary care offices and school based clinics. Methods: We interviewed clinicians in primary care offices and school-based clinics regarding their attitudes about HPV vaccine relative to Tdap and MCV4. Results: Respondents (n = 36) included clinical staff in family medicine (47%), pediatrics (25%), obstetrics/gynecology (19%) and school-based health clinics (8%). Only 3% strongly agreed and 17% agreed that completion of HPV vaccine was more important than completion of pertussis vaccine (Tdap), while 6% strongly agreed and 33% agreed that completion of HPV vaccine was more important than completion of meningitis vaccine (MCV4). Discussion: Providing clinicians with additional information about the cancer prevention benefits of the HPV vaccine and the greater risk for HPV infection/disease relative to other vaccine preventable adolescent diseases may help to increase HPV vaccination rates among adolescents.
