Although subungual squamous cell carcinoma is rare, it is the most common primary malignant neoplasms in this location. The higher incidence occurs in the fingernails, but involvement of the toenails is also possible. Subungual squamous cell carcinoma often looks like other more common benign lesions, such as fungal infection, onychomycosis, or viral wart. These factors, together with a general lack of awareness of this disease among physicians, often result in delayed diagnosis. Therefore, it is underdiagnosed, with few reports in the literature...

BACKGROUND: To determine if female partners of men with pathogen-negative non-gonococcal urethritis (NGU) are at risk of genital infection. METHODS: Secondary data analysis using health records from a large sexually transmitted disease clinic in Melbourne of 1710 men and their female partners attending on the same day from January 2006 to April 2015. Proportions of female partners with symptoms suggesting genital infection or pelvic inflammatory disease (PID) were determined for: (1) men with NGU and no Chlamydia trachomatis or Mycoplasma genitalium (referred to as pathogen-negative NGU) (n = 91); 2) men with urethral C...

Human papillomavirus (HPV)-induced cutaneous warts are potentially serious and debilitating. In immunosuppressed patients, these warts may be resistant to standard therapies. We report a case of a young patient with a primary immune deficiency whose recalcitrant cutaneous warts regressed completely following administration of a quadrivalent HPV vaccine.

Common cutaneous human papillomavirus (HPV) types induce skin warts, whereas species beta HPV are implicated, together with UV-radiation, in the development of non-melanoma skin cancer (NMSC) in immunosuppressed patients. Licensed HPV vaccines contain virus-like particles (VLP) self-assembled from L1 major capsid proteins that provide type-restricted protection against mucosal HPV infections causing cervical and other ano-genital and oro-pharyngeal carcinomas and warts (condylomas), but do not target heterologous HPV...

Antiphospholipid syndrome (APS) is an autoimmune hypercoagulable disorder characterized by thrombophilia, vascular thrombosis, and recurrent abortions associated with persistent antiphospholipid antibodies. APS may exist in its primary form, or more commonly is found to be associated with variety of rheumatic disorders, such as systemic lupus erythematosus. Cardiac involvement is not an uncommon complication in primary antiphospholipid patients. Libman-Sacks lesions are typically small, sessile, and wart-like, varying in size from 1-4 mm...

Avipoxvirus (APV) infections have been observed in a wide variety of wild, captive and domestic avian hosts, recently including a range of island endemic and endangered species. However, not enough is known about genome diversity and phylogenetic relationships of APVs, as well as their host-range specificity. A wild stone curlew (Burhinus oedicnemus) was recovered in Sardinia (Italy), showing large wart-like lesions and nodules on both legs and toes, which resulted positive to poxvirus by PCR. Histopathological examination of the lesions showed ballooning degeneration and large intracytoplasmic inclusion bodies consistent with APV infection...

Cervical cancer is the second most prevalent cancer among women, and it arises from cells that originate in the cervix uteri. Among several causes of cervical malignancies, infection with some types of human papilloma virus (HPV) is well known to be the greatest cervical cancer risk factor. Over 150 subtypes of HPV have been identified; more than 40 types of HPVs are typically transmitted through sexual contact and infect the anogenital region and oral cavity. The recently introduced vaccine for HPV infection is effective against certain subtypes of HPV that are associated with cervical cancer, genital warts, and some less common cancers, including oropharyngeal cancer...

Starting in 2006, vaccination against human papillomavirus (HPV) has been progressively implemented in most developed countries. Two vaccines have been successfully used, a bivalent vaccine targeting HPV-related cancers (bHPV) and a quadrivalent vaccine (qHPV) targeting both HPV-related cancers and genital warts. Between December 2014 and June 2015, a new nonavalent HPV vaccine (9vHPV) was granted marketing authorization in the USA and Europe. The 9vHPV was developed from the qHPV and includes five additional HPV types that should increase the level of protection toward HPV-related cancers...

Sexually transmitted diseases are a major public health problem both in developing and in developed countries, and especially with the co-synergy with HIV infection, there is an increasing need to have a proper understanding of the clinicodemographic patterns of sexually transmitted infections (STIs) for planning and implementing control strategies. Worldwide, there is an increased preponderance of viral STIs. Increasing incidence and altered clinical presentation of viral STIs in patients with HIV pose a diagnostic challenge; thereby, we studied the demographic profile of HIV-seropositive patients and compared clinical manifestations of viral STIs in HIV-seropositive patients to those in seronegative individuals...

Nagayasu Egawa, John Doorbar
Human Papillomavirus (HPV) research has been dominated by the study of a subset of Alpha papillomaviruses that together cause almost 5% of human cancers worldwide, with the focus being on the two most prominent of these (HPV16 and 18). These viruses are referred to as 'high-risk' (hrHPV), to distinguish them from the over 200 prevalent HPV types that more commonly cause only benign epithelial lesions. The 'low-risk' (lrHPV) term used to describe this group belies their cumulative morbidity. Persistent laryngeal papillomas, which occur rarely in children and adults, requires regular surgical de-bulking to allow breathing...

Onconase is a ribonuclease that presents both antitumor and antiviral properties linked to its ribonucleolytic activity and represents a new class of RNA-damaging drugs. It has reached clinical trials for the treatment of several cancers and human papilloma virus warts. Onconase targets different RNAs in the cell cytosol but Onconase-treated cells present features that are different from a simple arrest of protein synthesis. We have used microarray-derived transcriptional profiling to identify Onconase-regulated genes in two ovarian cancer cell lines (NCI/ADR-RES and OVCAR-8)...

Since 2006, three vaccines against infections and disease caused by human papillomavirus (HPV) became available in Europe-in 2006 a quadrivalent HPV 6/11/16/18 vaccine, in 2007 a bivalent HPV 16/18 vaccine and in 2015 a nonavalent HPV 6/11/16/18/31/33/45/52/58 vaccine. HPV 16 and 18 are the most oncogenic HPV strains, causing about 70% of cervical and other HPV-related cancers, HPV 6 and 11 cause 85% of all genital warts. The additional types of the polyvalent vaccine account for about 20% of invasive cervical cancer and >35% of pre-cancer...

Verrucous carcinoma of the foot is a rare malignancy, and proper diagnosis can be delayed. Furthermore, misdiagnosis often results in delayed appropriate treatment. Herein, we present an unusual case of verrucous carcinoma of the fifth toe with bone invasion in a 63-year-old woman that was mistaken for a plantar wart for 3 years. The condition was treated by ray amputation. We emphasize the need for appropriate biopsy to achieve an accurate diagnosis.

The large protocadherin Fat functions to promote Hippo pathway activity in restricting tissue growth. Loss of Fat leads to accumulation of the atypical myosin Dachs at the apical junctional region, which in turn promotes growth by inhibiting Warts. We previously identified Approximated (App), a DHHC domain palmitoyltransferase, as a negative regulator of Fat signaling in growth control. We show here that App promotes growth by palmitoylating the intracellular domain of Fat, and that palmitoylation negatively regulates Fat function...

High intensity-sweeteners (HIS) are natural or synthetic substances, sweeter than sugar, providing sweetness without calories. Sweeteners are mainly used as an aid in losing weight, preventing obesity and controlling blood sugar levels for diabetics. The objective of this study was to evaluate the carcinogenic potential of the sweeteners aspartame, sucralose, sodium saccharin and steviol glycoside, using the test for detection of epithelial tumor clones in Drosophila melanogaster. Larvae of 72 ± 4h, obtained from wts/TM3 female mated with mwh/mwh males, were treated for approximately 48h with different concentrations of aspartame (0...

BACKGROUND: Men who have sex with men (MSM) have a high lifetime risk of anogenital warts and cancers related to infection with human papillomavirus (HPV). They also benefit less from herd protection than heterosexual males in settings with female-only HPV vaccination. METHODS: We evaluated the potential health impact and cost-effectiveness of offering vaccination to MSM who visit genito-urinary medicine clinics. We used a mathematical model of HPV 6/11/16/18 sexual transmission within an MSM population in England, parameterised with sexual behaviour, GUM attendance, HPV prevalence, HIV prevalence, warts and cancer incidence data...
