Strong acids and strong alkaUes can severely bum the skin, chromium compounds can produce skin rashes, and repeated exposure to solvents causes removal of natural oils from the skin. Infection is always a concern for damaged skin. Absorption through the skin is possible for materials that are appreciably soluble iu both water and oil, eg, nitrobenzene, aniline, and tetraethyllead. Other materials can be absorbed if first dissolved iu extremely good solvents, eg, dimethyl sulfoxide. Subcutaneous iujection can occur accidentally by direct exposure of the circulatory system to a chemical by means of a cut or scratch or iuadvertent penetration of the skin with a hypodermic needle. 

For most ehemieals, inhalation is the main route of entry into the body. Penetration via damaged skin (e.g. euts, abrasions) should, however, be avoided. Certain ehemieals (e.g. phenol, aniline, eertain pestieides) ean penetrate intaet skin and so beeome absorbed into the body. This may oeeur through loeal eontamination, e.g. from a liquid splash, or through exposure to high vapour eoneentrations. Speeial preeautions to avoid skin eontaet are required with these ehemieals and potential exposure via skin absorption has to be taken into aeeount when assessing the adequaey of eontrol measures. 

May irritate damaged skin absorption can occur with effects similar to those via ingestion. 

Do not apply to broken or damaged skin or cover large areas. Wash hands immediately after application. 

When a diaper rash is already present, repairing the damaged skin, relieving discomfort, and preventing infection are important factors to consider when developing an effective treatment regimen. 

Experience profound compositional shifts in use May experience phases changes in use Site in the disease s location Operate at variable drug activity Highly nonstationary state kinetics Application technique and amount are highly individualized Applications short-acting Local tissue levels tied to efficacy Used on diseased, damaged skin No easy bioequivalency endpoint Systemic absorption absolutely undesirable, but some unavoidable... 

Bacterial infections of the skin can be classified as primary or secondary (Table 47-1). Primary bacterial infections are usually caused by a single bacterial species and involve areas of generally healthy skin (e.g., impetigo, erysipelas). Secondary infections, however, develop in areas of previously damaged skin and are frequently polymicrobic.

Any application of substances onto the skin, for instance, cosmetic products, must not cause damage to human health when applied under normal conditions. Therefore, any compound considered for application on human skin needs to be tested for reversible disadvantageous effects (skin irritation) and irreversible skin damage (skin corrosion). 

The bacteria that cause this disease overwinter in potato tubers, plant debris and soil. Tubers are invaded through damaged skin. Poor drainage, potassium deficiency, or excess nitrogen exacerbate the condition. 

For damaged skin, mild, nonantimicrobial skin-cleansing products may be used to remove dirt and debris. If antimicrobial action is needed (e.g.,...

Strong acids, bases, or oxidizers can cause permanent eye damage, skin bums, and, if swallowed, gastrointestinal damage. Examples of corrosive products include alkaline drain cleaners and oven cleaners, acid-based toilet bowl cleaners and rust removers, concentrated disinfectants, and some concentrated pesticides, especially fungicides.

Toxicosis in animals has resulted from ingestion of boric acid or borax solutions, from topical applications of boric acid solutions to damaged skin, and from inhalation of boranes the exact mechanisms of action are not understood. Boron and its compounds are potent teratogens when applied directly to the embryo, bnt there is no evidence of mutagenicity or carcinogenicity. Boron s unique affinity for cancerons tissnes has been exploited in neutron capture radiation therapy of malignant hnman brain tnmors.
