The common wart is caused by a virus, which invades the skin, producing the characteristic elevation of the skin or mucous membrane. Several forms occur. The common rough thickened plaques (verruca vulgaris) occur frequently in childhood. They are most familiar on the hands, fingers, and around the nails. Satellite lesions may occur, or they may appear in areas of trauma. Small capillaries, when thrombosed, may exhibit black dots, resembling seeds.

Flat warts are multiple skin-colored papules on the face, neck, or the back of the hand. Around the eye or mouth small pointed (filiform) warts may appear like soft pliable tags. A most difficult wart to eradicate is the one found on the sole or plantar wart, occurring in the thick calloused skin of the feet. It is important to differentiate these from corns or callouses. A final type of wart is seen in the genital area, called condyloma accuminata. These cauliflower— shaped, warty clusters may extend into the vaginal or rectal mucosa. Usually related to sexual contact, they may become quite painful.

There are several acceptable methods of treating warts. Electric needles can be used to dry up the warts, but this usually requires local anesthesia. Chemicals such as bichloracetic acid can destroy the wart tissue and, when carefully controlled to depth of penetration, it is usually successful. More recently cryosurgery is used, freezing the lesion with liquid nitrogen or with a special instrument utilizing carbon dioxide as the cooling agent. Most treatments of warts work by liberating the virus into the circulation, thus exposing it to antibodies. The usual type of warts on the hands should be frozen with liquid nitrogen or treated with chemicals, such as salicylic acid and lactic acid (duofilm), trichloracetic acid, ammoniated mercury ointment, or cantharidine (Cantharone). These treatments will not usually leave a scar.

Electrosurgery is also effective, and for most lesions the remaining scar will not be too visible. Approximately 20% of the warts resolve spontaneously within one year. Plantar warts should be treated carefully with a nonscarring procedure. Permanent scars may be painful. Gentle excavation of the wart with a scraping instrument (curette). Also, the use of chemical irritants or freezing measures are usually quite effective. The venereal wart (condyloma accuminata) can be a real therapeutic challenge. One treatment involves an application of a special solution, 25% podophyllin in tincture of benzoin. Caution is required, because of skin irritation risk. This treatment should NEVER be used during pregnancy!

The study of warts can be challenging, because of the antigen-antibody relationships of this ubiquitous virus. It has provided a model for understanding the production of tumors. This some day may help us develop safer and more physiologic ways of fighting other viruses, such as those that cause various types of cancer.

This viral disease affects the mucous membranes as well as the skin. It produces multiple raised reddened lesions, each having a small central crater. The size is less than ¼ inch (2 to 4mm). Clusters of lesions tend to erupt in groups or lines. These papules emit a thick white material with pressure. They spread by contact. In order to remove them, a method must be chosen that minimizes scar formation and pain. Freezing with liquid nitrogen, the use of a comedone extractor, or disruption of the central core with a scalpel or sterilized needle can produce rapid relief with insignificant scarring.

Chicken pox or varicella is caused by a virus in the same family as Herpes simplex. The virus produces in adults a disease called Herpes zoster or shingles. The childhood variety is quite typical with a reddened rash, becoming raised and developing small blisters. These evolve in various stages and eventually form crusts. This disease is contagious and is probably transmitted from one person to another through the skin or respiratory tract. Severe itching, however, can lead to secondary bacterial infection. Sometimes deep scabs produce permanent scarring. Topical drying lotions can give relief of itching, while specific treatment of secondary bacterial infections is essential.

Zoster or shingles is a second disease caused by the same Herpes virus. The first manifestation of this condition is usually severe pain, localized to one side and following a nerve distribution in the face, neck, or trunk. At this early stage of the disease the condition may be misdiagnosed as a heart attack, hiatus hernia, migraine, or other pain syndrome. Several days later, however, the eruption appears as grouped reddened papules that rapidly evolve into tiny blisters distributed on the skin over the nerve (called the dermatome). Diagnosis is usually simple at this stage, while therapy is more difficult.

Although complications are rare and contagion is uncommon, in elderly people severe pain may persist. This is called “postherpetic neuralgia.” It is rare in patients younger than 50 years, but may be quite disabling to the elderly. The shingles infection itself is self-limited. Topical drying lotions are helpful. A relatively new cream is now available for pain control. Called Zostrix, it is actually based on cayenne pepper, containing the ingredient capsicum.

In our institution I have seen relief from a series of steam baths, producing a mild fever. Just as the fever helps fight the childhood viral disease, I find fever effective in reducing the sequelae of this disease and hastening the clearing of the rash. Moist compresses, such as the use of a charcoal poultice, can also reduce the pain and local inflammation over the involved nerve. Sprays, such as Dermaplast, may produce temporary relief for the pain and irritation. Experimental treatment using the smallpox vaccine for shingles patients was studied and found ineffective.

Painful ulcerating lesions around the mouth, on the face, and in the genital region are usually caused by a virus, called Herpes simplex. These lesions, frequently called cold sores or fever blisters, may follow an infection. Respiratory illness, influenza, or serious bacterial diseases are some of the common triggers. Nearly everyone is exposed to the Herpes simplex virus during childhood or young adult life. In most individuals a gradual immunity develops, In the unfortunate others, the Herpes virus invades a regional nerve. From this protected position it periodically spawns the skin reaction. A second type of Herpes simplex virus involves the genital organs. Transmitted usually by sexual relations, Herpes ulcers may become extremely painful. If present during late pregnancy, Herpes can provoke a serious, occasionally fatal, viral infection of the newborn.

Herpes simplex is frequently triggered by prolonged exposure to sunlight. Fever, trauma, menstruation, and cold exposure, as well as anxiety may be contributory causes. Because a sensory nerve is irritated, numbness or tingling may be present, associated with the skin lesions. Involvement of the brain (meninges), the cornea, or Herpes infections superimposed on eczema are more serious diseases. They should be evaluated by a skilled physician. Specific antiviral agents are somewhat experimental, all with potential side effects. The treatment of keratitis (infection of the cornea) is urgent, to prevent ulceration and blindness.

Several simple treatments are most helpful for cold sores about the mouth or other skin locations. They act as drying agents to the skin, including camphor, alcohol, and similar proprietary medications. Topical hydrocortisone containing creams (corticosteroids) can be applied for temporary symptomatic relief.

A very distressing condition that occurs primarily among adolescents is acne vulgaris. Although the exact cause of this troubling affliction is not completely known, acne is definitely associated with hormone changes. These include those that cause sexual maturation and growth during the teenage years. Skin variations take several possible courses. Frequently, around the face, neck, and back ones hair follicles will become plugged with a waxy secretion that appears as the typical blackhead (comedone). These plugs can be removed with a “comedone extractor.” The device can be purchased at any pharmacy. Using this instrument is much preferable to pinching the pimple. Traumatizing the skin can spread infection.

Obstruction to drainage of this material can develop a bacterial infection, producing the typical whitehead or pustule. These may be large and extensive, In more serious forms, called cystic acne, infection may produce permanent scarring. A high fat diet, rich in fried or greasy foods, or meat and cheese, frequently changes the oil secretions on the skin and thus aggravates this tendency. Average teenage diets are often low in natural seed oils, nuts, fruits, and grains. This further enhances the development of acne. Poor diets may perpetuate it for several years.

Combined with high—fat dietary patterns is the increasing use of fashionable cosmetics. Most of them block the pores and prevent the skin from breathing. There are dozens of skin remedies available in pharmacies today. However, I find the following remedial agencies important, both in prevention and treatment of acne.

The skin must be cleansed once or twice daily with an antiseptic soap.This reduces the germ count and prevents the bacterial colonization in deeper pores that may be plugged. Blackheads and other lesions should never be squeezed or picked at, particularly with dirty hands or fingernails. Whiteheads can be treated, as mentioned above for furuncles, with incision and drainage after appropriate antiseptic preparation. Sunlight exposure is important, not only to curtail bacterial colonization, but for general toning of the skin to resist disease.

Teenager’s diets should be simple but varied, with adequate vitamin and mineral composition, and a strong emphasis on fruits, whole grains, nuts, and vegetables. Butter fats, cocoa, coconut, meat, and fried greasy foods should be strictly avoided. Most saturated fats tend to clog the pores. Soymilk is valuable to further reduce any dietary source of cholesterol or saturated fat. Sugar intake should be restricted to aid general resistance to infection. Habits of adequate rest, daily exercise, and frequent bathing are most advantageous.
