Davod Javanmard, Mahmoodreza Behravan, Malaknaz Ghannadkafi, Alireza Salehabadi, Masood Ziaee, Mohammad Hasan Namaei
Background: Chlamydia trachomatis (CT), the most common bacterial sexually transmitted infection (STI), leads to pelvic inflammatory disease, infertility and chronic pelvic pain in women as well as an increased risk of vertical transmission, conjunctivitis and pneumonitis in infants. It may also be a co-factor along with human papillomavirus (HPV) in cervical cancer progression. We aimed to determine the prevalence of CT genotypes in genital specimens of women from South Khorasan, Iran and to test the association between CT and cytology statistics...

AIM: There is strong evidence to suggest vertical and horizontal modes of transmission of human papilloma virus (HPV), an established etiologic agent of cervical cancer. Infants, children, and adults can acquire both high-risk and low-risk infections by birth or by close contact even though HPV is mainly transmitted sexually. A thorough review of the literature was performed to assess the possible non-sexual modes of transmission of HPV. METHODS: An electronic search of databases for review articles, cross-sectional studies, cohort studies, and case reports on non-sexual modes of transmission among sexually unexposed women and children was carried out using search terms such as "human papilloma virus, HPV, transmission, horizontal transmission, vertical transmission, and fomites"...

BACKGROUND: There is much evidence that high-risk human papillomavirus (HPV) plays a causative role in a subset of head and neck squamous cell cancer (HNSCC) in adults. HPV-positive tumors behave differently even in their response to treatment and are therefore a distinct subset. Both HPV-positive and HPV-negative tumors of the head and neck region are usually in the domain of adults and cases in children are rare; thus when a 2‑year-old child was diagnosed with this cancer in the external auditory canal, an in-depth assessment of the tumor was considered necessary...

There is growing evidence that HPV infection is possible through non-sexual routes like mother to-child transmission in the perinatal period. Human papillomavirus (HPV) infection has traditionally been regarded as a sexually transmitted disease (STD), but recent evidence implicates that an infected mother can transmit HPV to her newborn during pregnancy, at delivery, perinatal period or later. There is evidence of vertical transmission, presumably occurring during passage of the fetus through an infected birth canal...

The human papillomavirus (HPV) is a sexually transmitted infection common among men and women across all geographic and socioeconomic subgroups worldwide. Recent evidence suggests that HPV infection may affect fertility and alter the efficacy of assisted reproductive technologies. In men, HPV infection can affect sperm parameters, specifically motility. HPV-infected sperm can transmit viral DNA to oocytes, which may be expressed in the developing blastocyst. HPV can increase trophoblastic apoptosis and reduce the endometrial implantation of trophoblastic cells, thus increasing the theoretical risk of miscarriage...

INTRODUCTION AND OBJECTIVE: Human papillomavirus (HPV) infection is the most common human sexually transmitted disease. It is clinically relevant because this condition is necessary for the development of epithelial cervical cancer, and it is also a factor closely associated with the occurrence of diverse tumours and various benign and malignant lesions of the head and neck area. The infective mechanism in most of these cases is associated with sexual intercourse, but there is recent scientific evidence suggesting that HPV infection may also be acquired by other routes of infection not necessarily linked to sexual contact...

INTRODUCTION: Human Papillomavirus (HPV) is a group of DNA viruses which is an etiological factor of many benign and malignant diseases of the upper respiratory tract mucosa, female genital tract and the skin. HPV infection is considered a sexually-transmitted infection, but can also be transmitted by non-sexual routes, including perinatal vertical transmission, physical contact, iatrogenic infection and autoinoculation. Recurrent Respiratory Papillomatosis (RRP) in children is connected with HPV infection transmitted vertically from mother to child during the passage of the foetus through an infected birth canal...

INTRODUCTION: Human papillomavirus (HPV) is the most common sexually transmitted infection. Data reporting vertical transmission of HPV from the mother to the fetus are inconsistent and scant. Vertical transmission may occur by hematogenic route (transplacental), or by ascending contamination, or through the birth canal, which may result in the dreaded and rare laryngeal papillomatosis. Infected sperm at fertilization is a potential route of infection, too. OBJECTIVE: The objective of the study was to evaluate the rate of vertical transmission of HPV in HPV-positive pregnant women to their newborn infants, as well as the risk factors of HPV vertical transmission...

Human papillomaviruses (HPVs) are estimated to be the most common sexually transmitted virus in humans. The virus is of great interest as it is the etiological agent of cervical cancer. Sexual transmission of HPV is generally accepted, however, non-sexual transmission of the virus is often debated. Here, we review the evidence from basic research and clinical studies that show HPV can survive well outside of its host to potentially be transmitted by non-sexual means. In doing so, we hope to discover problems in current prevention practices and show a need for better disinfectants to combat the spread of HPV...

Human papillomavirus (HPV) is composed of a particularly heterogeneous family of DNA viruses, which has gained much attention in recent years due to the discoveries of Professor Harald zur Hausen, who first identified a connection between HPV and cervical cancer. Professor Harald zur Hausen, the 'Father of HPV Virology', was the recipient of the 2008 Nobel Prize. HPV can be transmitted through physical contact via autoinoculation or fomites, sexual contact, as well as vertically from the HPV-positive mother to her newborn, causing subclinical or clinical infections...

In recent years, there have been major advances in our understanding of the biology and natural history of Human Papilloma Virus (HPV). Most papillomavirus infections are transmitted by close contact of either skin to skin or mucosa to mucosa. Sexual intercourse is not a requirement for genital HPV infection. Digital-oral infections occur and there is evidence that digital-genital and oral-genital contacts can result in the transmission of HPV, although in a relatively low percentage. Vertical transmission from mother to fetus is a common route of infection; in fact, it is recognized that more than 80% of infants born from mothers infected with genital HPV will be positive for HPV DNA determination in the nasal-pharyngeal region and oral mucosa...

OBJECTIVES: Little to nothing is known about human papillomavirus (HPV) susceptibility to disinfection. HPV is estimated to be among the most common sexually transmitted diseases in humans. HPV is also the causative agent of cervical cancers and other anogenital cancers and is responsible for a significant portion of oropharyngeal cancers. While sexual transmission is well documented, vertical and non-sexual transmission may also be important. METHODS: Using recombinant HPV16 particles (quasivirions) and authentic HPV16 grown in three-dimensional organotypic human epithelial culture, we tested the susceptibility of high-risk HPV to clinical disinfectants...

Despite identification of important risk factors, aetiology of nasopharyngeal cancer (NPC) remained enigmatic. Oncogenic Human Papillomavirus (HPV), a cause of cervical and genital tract epithelial cancers, has recently been isolated from NPC tumour tissues, raising the question of whether HPV may play a role in NPC. Accumulating evidence showed that perinatal HPV transmission to newborns can occur through exposures to genital tract secretions, amniotic fluid, or blood during vaginal delivery in mothers with cervical HPV infection, with viral DNA fingerprint showing maternal-foetal concordance...

BACKGROUND: Condyloma acuminata are caused by human papilloma virus (HPV) 6 and 11 and most commonly present in the anogenital region. Most transmission among adults is via sexual transmission, but HPV and resulting anogenital warts in pediatric populations may be a result of perinatal vertical transmission, indirect transmission through contaminated objects or surfaces, autoinoculation, or sexual transmission. CASE: A 9-year-old premenarchal female presented with multiple perianal warts...

Chronic viral infections can infect sperm and are considered a risk factor in male infertility. Recent studies have shown that the presence of HIV, HBV or HCV in semen impairs sperm parameters, DNA integrity, and in particular reduces forward motility. In contrast, very little is known about semen infection with human papillomaviruses (HPV), herpesviruses (HSV), cytomegalovirus (HCMV), and adeno-associated virus (AAV). At present, EU directives for the viral screening of couples undergoing assisted reproduction techniques require only the evaluation of HIV, HBV, and HCV...

Currently, human papillomavirus (HPV) research focuses on HPV infection in adults and sexual transmission. Data on HPV infection in children are slowly becoming available. It is a matter of debate whether mother-to-child transmission of HPV is an important infection route and whether children born to HPV-positive mothers are at a higher risk of HPV infection compared with children born to HPV-negative mothers. The objective of this meta-analysis is to summarize the published literature on the extent to which genital HPV infection is vertically transmitted from mother to child...

OBJECTIVES: To elucidate the concordance of human papillomavirus (HPV) genotypes between the mother and her newborn and to identify risk factors for the vertical transmission of HPV. STUDY DESIGN: HPV genotypes present in 329 pregnant women, their newborns, cord blood, and placenta samples were determined by molecular techniques, including using pure DNA for nested polymerase chain reaction. HPV antibodies were tested using multiplex HPV serology. Kappa statistics and the Wilcoxon test were used to assess concordance, and regression analysis was used to calculate ORs and 95% CIs...

Viral infections in pregnancy are a major cause of morbidity and mortality for both mother and fetus. Viral STIs occur as surface infection and then gradually infect immunologically protected sites. Therefore, these are asymptomatic, hidden and hence underdiagnosed, persistent and difficult to treat. HSV, HPV, HBV, HIV and CMV (cytomegalovirus) are the common ones. Most of these are transmitted during intrapartum period. Proper screening, identification and treatment offered during prenatal period may help in preventing their complications...

Human papillomavirus (HPV) DNA has been detected in the oral cavity of infants and breast cancer tissue, suggesting its vertical transmission through maternal milk. We determined whether HPV is detected in maternal milk and is vertically transmitted by breast-feeding. Informed consent was obtained, and maternal milk samples (n=80) were analysed for high-risk HPV DNA. In 43 women, this DNA was measured in the uterine cervix. In women with positive samples, this DNA was measured in the oral cavities of their children...

BACKGROUND: Public awareness of human papillomavirus (HPV) as the causal agent of cervical cancer and of the availability of HPV vaccines has increased. As a result, more patients are asking their dentists about oral HPV infection and its prevention by means of vaccination. Parents of pediatric dental patients also may be concerned when their children have HPV-associated oral lesions, because HPV infection still often is considered a purely sexually transmitted disease. In this review, the authors provide the latest information for dental professionals about HPV infection in the oral mucosa and in general...
