Warts
Warts are non-cancerous viral growths usually occurring on the hands and feet but which can also affect other locations, such as the genitals or face. One or many warts may appear. They are distinguished from cancerous tumors as they are caused by a viral infection, such as a human papillomavirus, rather than a cancer growth. Factors that increase the risk include the use of public showers and pools, working with meat, eczema, and a weak immune system. The virus is believed to infect the host through the entrance of a skin wound. A number of types exist, including plantar warts, " filiform warts", and genital warts. Genital warts are often sexually transmitted. Without treatment, most types of warts resolve in months to years. A number of treatments may speed resolution, including salicylic acid applied to the skin and cryotherapy. In those who are otherwise healthy, they do not typically result in significant problems. Treatment of genital warts differs from that of o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genital Wart
Genital warts are a sexually transmitted infection caused by certain types of human papillomavirus (HPV). They may be flat or project out from the surface of the skin, and their color may vary; brownish, white, pale yellow, pinkish-red, or gray. There may be a few individual warts or several, either in a cluster or merged together to look cauliflower-shaped. They can be itchy and feel burning. Usually they cause few symptoms, but can occasionally be painful. Typically they appear one to eight months following exposure. Warts are the most easily recognized symptom of genital HPV infection. HPV types 6 and 11 are responsible for causing majority of genital warts whereas HPV types 16, 18, 31, 33, and 35 are also occasionally found. It is spread through direct skin-to-skin contact, usually during oral, manual, vaginal, or anal sex with an infected partner. Diagnosis is generally based on symptoms and can be confirmed by biopsy. The types of HPV that cause cancer are not the same a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Papillomavirus
Human papillomavirus infection (HPV infection) is caused by a DNA virus from the ''Papillomaviridae'' family. Many HPV infections cause no symptoms and 90% resolve spontaneously within two years. In some cases, an HPV infection persists and results in either warts or precancerous lesions. All warts are caused by HPV. These lesions, depending on the site affected, increase the risk of cancer of the cervical cancer, cervix, vulva cancer, vulva, vaginal cancer, vagina, penis cancer, penis, anal cancer, anus, oropharyngeal cancer, mouth, tonsils, or throat. Nearly all cervical cancer is due to HPV, and two strains – HPV16 and HPV18 – account for 70% of all cases. HPV16 is responsible for almost 90% of HPV-positive oropharyngeal cancers. Between 60% and 90% of the other cancers listed above are also linked to HPV. HPV6 and HPV11 are common causes of genital warts and laryngeal papillomatosis. An HPV infection is caused by the ''human papillomavirus'', a DNA virus from the papi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantar Wart
A plantar wart is a wart occurring on the bottom of the foot or toes. Its color is typically similar to that of the skin. Small black dots often occur on the surface. One or more may occur in an area. They may result in pain with pressure such that walking is difficult. They are caused by the human papillomavirus (HPV). A break in the skin is required for infection to occur. Risk factors include use of communal showers, having had prior warts, and poor immune function. Diagnosis is typically based on symptoms. Treatment is only needed if it is causing symptoms. This may include salicylic acid, cryotherapy, chemo-based fluorouracil or bleomycin, and surgical removal. The skin atop the lesion should generally be removed before treatment. In about a third to two-thirds of cases, they go away without specific treatment, but this may take a few years. Plantar warts are common. Children and young adults are most often affected. Signs and symptoms Their colors are typically s ...

HPV Vaccine
Human papillomavirus (HPV) vaccines are vaccines intended to provide acquired immunity against infection by certain types of human papillomavirus. The first HPV vaccine became available in 2006. Currently there are six licensed HPV vaccines: three bivalent (protect against two types of HPV), two quadrivalent (against four), and one nonavalent vaccine (against nine) All have excellent safety profiles and are highly efficacious, or have met immunobridging standards. All of them protect against HPV types 16 and 18, which are together responsible for approximately 70% of cervical cancer cases globally. The quadrivalent vaccines provide additional protection against HPV types 6 and 11. The nonavalent provides additional protection against HPV types 31, 33, 45, 52 and 58. It is estimated that HPV vaccines may prevent 70% of cervical cancer, 80% of anal cancer, 60% of vaginal cancer, 40% of vulvar cancer, and show more than 90% effectiveness in preventing HPV-positive orophary ...

Periungual Wart
Periungual warts are warts that cluster around the fingernail or toenail. They appear as thickened, fissured cauliflower-like skin around the nail plate. Periungual warts often cause loss of the cuticle and paronychia. Nail biting increases susceptibility to these warts. Warts of this kind often cause damage to the nail either by lifting the nail from the skin or causing the nail to partially detach. If they extend under the nail, then the patient may suffer pain as a result. Sometimes periungual wart infections resemble the changes that are found in onychomycosis. In worst cases, if the infection causes injury or damage to the nail matrix, deformity in the nail may become permanent. As with other wart types, a number of treatments are available, including laser therapy, cryotherapy, salicylic acid, and other topical treatments. Signs and symptoms Periungual warts are warts that develop next to the hand and foot nails. Usually, warts appear as tiny, scratchy papules that rese ...

Verruca Plana
Flat warts, technically known as verruca plana, are reddish-brown or flesh-colored, slightly raised, flat-surfaced, well-demarcated papule of 2 to 5 mm in diameter. Upon close inspection, these lesions have a surface that is "finely verrucous".Lookingbill, Donald, et al. ''Principles of Dermatology''. Saunders. 2000. Pages 68-69. . Most often, these lesions affect the hands, legs, or face, and a linear arrangement is not uncommon. At histopathology, flat warts have cells with prominent perinuclear vacuolization around pyknotic, basophilic Basophilic is a technical term used by pathologists. It describes the appearance of cells, tissues and cellular structures as seen through the microscope after a histological section has been stained with a basic dye. The most common such dye ..., centrally located nuclei that may be located in the granular layer. Last Update: May 13, 2019. These are referred to as "owl's eye cells."

Sexually Transmitted
A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is spread by sexual activity, especially vaginal intercourse, anal sex, oral sex, or sometimes manual sex. STIs often do not initially cause symptoms, which results in a risk of transmitting them to others. The term ''sexually transmitted infection'' is generally preferred over ''sexually transmitted disease'' or ''venereal disease'', as it includes cases with no symptomatic disease. Symptoms and signs of STIs may include vaginal discharge, penile discharge, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility. Bacterial STIs include chlamydia, gonorrhea, and syphilis. Viral STIs include genital warts, genital herpes, and HIV/AIDS. Parasitic STIs include trichomoniasis. Most STIs are treatable and curable; of the most common infections, syphilis, gonorrhea, chlamydia, and trichom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digitate Wart
Digitate or filiform warts are warts that often appear on the eyelids, lips, face, or neck. The warts tend to grow directly outwards from the skin. They have a spiky, thread-like or finger-like appearance. They sometimes look and feel like tiny brushes, making them especially uncomfortable for the patient. As with other wart types, a number of treatments are available, including laser therapy, cryotherapy, salicylic acid Salicylic acid is an organic compound with the formula HOC6H4COOH. A colorless (or white), bitter-tasting solid, it is a precursor to and a active metabolite, metabolite of acetylsalicylic acid (aspirin). It is a plant hormone, and has been lis ..., and other topical treatments. References {{Reflist Papillomavirus-associated diseases ...
