PURPOSE: Cervical cancer is the fourth most common cancer in women worldwide with very high incidence in India. Liquid-based cytology (LBC) provides the use of ancillary techniques in addition to a good morphology and detection of cytologic abnormalities. The current study was designed to assess the diagnostics of P16INK4a immunoexpression, p16 promoter hypermethylation, human papilloma virus (HPV), and DNA ploidy in LBC samples with cervical precancer and cancer. METHODS: A series of LBC samples categorised by Bethesda system including 22 atypical squamous cells of undetermined significance (ASC-US), 21 low-grade squamous intraepithelial lesion (LSIL), 41 high-grade squamous intraepithelial lesion (HSIL), 54 squamous cell carcinoma (SCC), and 26 controls with normal cytology were included...

BACKGROUND AND PURPOSE: Human papillomavirus-related oropharyngeal squamous cell carcinoma is associated with cystic lymph nodes on CT and has a favorable prognosis. A subset of patients with aggressive disease experience treatment failure. Our aim was to determine whether the extent of cystic lymph node burden on staging CT can serve as an imaging biomarker to predict treatment failure in human papillomavirus-related oropharyngeal squamous cell carcinoma. MATERIALS AND METHODS: We identified patients with human papilloma virus-related oropharyngeal squamous cell carcinoma and staging neck CTs...

Verrucae are benign epithelial proliferations, characteristically 1-20 mm in diameter, caused by human papilloma virus (HPV) infection occurring on the skin and mucosa (Photomed Laser Surg 33(6):338-42, 2015; Lasers Med Sci 29(3):1111-6, 2014). Prevalence of verrucae is 5-20% in children and young adults with peak incidence reported during teenage years (Lasers Med Sci 29(3):1111-6, 2014; J Am Acad Dermatol 22(4):547-66, 1990; J Korean Med Sci 24(5):889-93, 2009). Patients often express significant displeasure with quality of life due to this cosmetic insecurity, as well as functional problems and physical discomfort when they occur on palms of hands and soles of feet...

Using key words online databases were searched to identify relevant publications to review the use of Human papilloma virus (HPV) in cervical screening. The mode of cervical screening in the UK has been decided but implementation plans have yet to be announced. The protracted uncertainty surrounding the initial announcement to move to HPV primary screening together with the lack of a national steer has resulted in a flight of staff which threatens the provision of the current and future service. The transition will be a challenging time but analysis of data from more than 176,000 women has shown clear evidence of a reduction in the incidence of cancer where HPV testing is used...

Human papillomavirus (HPV) belongs to the Papillomaviridae family and infects squamous cells and mucous membranes of humans. Various studies conducted over the last years have shown a correlation between HPV infection and carcinogenesis process. The DNA of the virus is detected in approximately 20% of cancers of the upper respiratory tract. The presence of HPV in cancerous lesion of the larynx varies depending on the procedure applied for sample collection and the viral DNA detection method. The high variance in the frequency of HPV detection is observed even among results obtained with the use of PCR reaction...

Gastrointestinal cancers are a global public health problem, which represent a vast majority of all cancer-caused deaths in both men and women. On the other hand, viral pathogens have been long implicated as etiological factors in the onset of certain human cancers, including gastrointestinal tumors. In this regard, Human Papilloma Virus (HPV), Epstein-Barr Virus (EBV), and John Cunningham Virus (JCV) have been more strongly suggested to be involved in gastrointestinal carcinogenesis; so that, the association of HPV with oropharyngeal and anal cancers and also the association of EBV with gastric cancer have been etiologically confirmed by epidemiological and experimental investigations...

BACKGROUND: In 2008, a school-based human papilloma virus (HPV) vaccination program was implemented in the province of Québec. Grade 4 girls (9-10 years old) are routinely vaccinated and grade 9 to 12 girls (14-17 years old) were eligible for the catch-up vaccination. Vaccine coverage of the targeted cohorts was estimated at 76-81%. To assess if HPV vaccination is associated with an increase in GBS hospitalisation, we compared the hospitalization rates of GBS in HPV vaccination targeted and non-targeted groups...

AIM: No association between human papilloma virus (HPV) vaccination and numerous diseases has been found. Still, a large number of Danish women are reporting suspected adverse events. Other factors may play a role, and the aim of this study is to examine the association between psychiatric conditions, general practitioner (GP) attendance and indicators of psychological symptoms prior to HPV vaccination and the risk of referral to an HPV center following vaccination. STUDY DESIGN AND SETTING: Register-based, matched case-control study...

A cutaneous horn could be defined as a conical projection on the surface of skin made of cornified material and resembling an animal horn. These lesions most commonly affect light-skinned men aged between 50 to 89 years and usually appear in sun exposed areas. Radiation, chronic irritation and even human papilloma virus-2 infection may be precipitating factors. More than half of the cases originate from either malignant or premalignant lesions, therefore the base of the lesion must be carefully examined histologically...

HPV Vaccine was introduced to prevent cervical cancer known to be caused by infection with one or more of the high risk subtypes of the Human papilloma virus (HPV). Since introduction, trials have proven its efficacy in preventing Cervical intraepithelial neoplasia (CIN) beyond doubt and its effectiveness in preventing cervical cancer though presumptive is reasonably certain as per mathematical modelling. It also prevents other HPV related anogenital and oropharyngeal malignancies in both sexes. HPV vaccines have courted many controversies related to its efficacy, safety, ideal age of vaccination, use in HPV infected individuals and use in males...

Penile carcinoma is a rare genitourinary malignancy in North America and Europe with highest rates recorded in South America, Africa and Asia. Recent classifications have refined the terminology used in classifying intraepithelial/in situ lesions and additionally newer entities have been recognised in the invasive category. While increasing recognition of a bimodal pathway of penile carcinogenesis has facilitated understanding and classification of these tumours, handling and subtyping of penile malignancies presents a challenge to the reporting pathologist, in part due to their rarity...

The increasing proportion of human papilloma virus-related oropharynx cancers has led to improved success in the treatment of this disease. However, the current low recurrence rate after treatment of oropharyngeal cancer highlights the continued need for, as well as the challenges of, designing an effective follow-up surveillance program. There are frequently multiple modalities used in the treatment of oropharyngeal cancer, resulting in short- and long-term tissue changes to the head and neck that challenge clinical distinction of recurrence versus treatment-related changes...

BACKGROUND: Penile cancer is an uncommon malignancy in developed countries, but the incidence is as high as 10% to 20% of all male cancers in some developing countries. There is a paucity of published data on this subject in our setting. This study describes the clinicopathological presentation and treatment outcome of this condition in our environment, and highlights challenges associated with the care of these patients and proffers solutions for improved outcome. METHODS: This was a retrospective study of histologically confirmed cases of penile cancer seen at Bugando Medical Centre between January 2004 and December 2013...

In this study, we investigated the effects of the natural antioxidant curcumin on the HPV16-positive oral carcinoma cell line 93VU147T and demonstrated that curcumin is not only a potent inhibitor for the activity of host nuclear transcription factors AP-1 and NF-kB but it also selectively suppresses transcription of the HPV16/E6 oncogene during the carcinogenic process in oral cancer cells. This study suggests a therapeutic potential of curcumin for high-risk human papilloma virus (HPV)-infected oral cancers...

BACKGROUND: Squamous cell papilloma is a benign mucosal disease associated with human papillomavirus. Its presence in human immunodeficiency virus (HIV)-infected patients has rarely been reported. Therapeutic modalities for oral squamous cell papilloma have limited success and recurrences are frequent in HIV-infected subjects. Imiquimod, is a topical immunomodulator successfully used in some human papillomavirus-related oral lesions. However, its use for oral squamous cell papillomas in HIV-infected individuals has never been described...
