A Preservative and stabilizer used in latex concentrate.

Ana-phy-lac-tic shock: an often severe and sometimes fatal systemic reaction in a susceptible individual upon exposure to a specific antigen after previous sensitization. Characterized by respiratory symptoms, fainting, itching and urticaria.

Ana-phy-lax-is: hypersensitivity resulting from sensitization following prior contact with the causative agent. An immediate systemic allergic reaction to a foreign protein or other substance. The reaction results from the release of histamine and other substances when allergen combines with IgE antibodies on mast cell surfaces. There are receptor sites for histamine on the surface of blood vessels. When triggered, the vessels dilate, letting fluid (not red blood cells) leak out into the surrounding area. This can be local, as seen in the raised surface of a hive, or it may the systemic. If the release of fluids from the circulatory system is systemic, the lost volume results in hypotension (drop in blood pressure). The heart increases its speed to compensate (tachycardia). If sufficiently severe, it can lead to anaphylactic shock and, rarely death.

The immunologic state induced in a susceptible individual by an allergen characterized by a marked change in the subject’s reactivity. Both Type I and Type IV hypersensitivities are allergies (e.g. Type I = latex protein allergy, hay fever, penicillin allergy; Type IV = chemical accelerators, nickel, poison oak).

Chlorination

Chloroprene

Circumscribed

Class I Medical Device

Class II Medical Device

2-Chloro-1,3-Butadiene. A colorless liquid organic compound used in the synthesis of neoprene and certain other rubbers. The structure of the chloroprene molecule is very similar to that of isoprene; the molecule contains two double bonds and is readily polymerized.

Instead of powdering, some manufacturers dip gloves into a chlorinated solution (for example, sodium hypochlorite acidified with hydrochloric acid). This process reacts with the natural rubber latex to reduce tackiness, eliminating the need for additional dusting powder. Also, extra washing performed during chlorination provides an added benefit by greatly reducing the level of soluble latex proteins. It also affects some mechanical and physical glove characteristics (e.g. softness and color).

A device for which the controls authorized by or under sections of the Federal Food, Drug and Cosmetic Act are sufficient to provide reasonable assurance of the safety and effectiveness of the device.

A device that cannot be classified as a Class I device because the sections of the Federal Food, Drug and Cosmetic Act by themselves are insufficient to provide reasonable assurance of the safety and effectiveness of the device and for which there is sufficient information to establish special controls to provide such assurance, including the dissemination of guidelines.

Within a well-defined area or in one with definite boundaries or limits. A hive has a circumscribed region of swelling.

See Chlorination. Corrosive compounds that can burn skin and eyes, as well as discolor fabrics and vinyl. They are inactivated by protein based materials and are not registered by the EPA. Common brands include Clorox.

The treatment, mostly of cancer, using a series of cytotoxic drugs that attack cancerous cells. This treatment commonly has adverse side effects that may include the temporary loss of the body's natural immunity to infections, loss of hair, digestive upset, and a general feeling of illness. Although unpleasant, the adverse effects of treatment are tolerated considering the life-threatening nature of the cancers. Gloves can be tested for use with chemotherapeutic drugs. The FDA currently requires testing to publish the claim that any glove is appropriate for use with chemotherapy drugs. Appropriate products include thicker (greater than 0.10 mm) latex and nitrile examination gloves.

A compound made by polymerizing two or more dissimilar monomers

A chemical agent used in the manufacturing process of latex rubber that may elicit a delayed type allergic reaction (Type IV) after repeated contact with the epidermis of a susceptible individual. The Type IV reaction is usually triggered when the contact sensitizer dissolves in perspiration and is absorbed through the epidermis. Symptoms are usually mitigated with time after removal of the offending substance from skin contact. The most common latex-related contact sensitizers are accelerators such as thiurams, mercaptobenzothiazole and carbamates. Other chemical additives (antioxidants, preservatives, etc.) have been reported as possible contact sensitizers, for example Butylhydroxyanisol (BHA) and 3,5-di-tertiary butyl 4-hydroxytoluene (BHT) 4,4-thiobis (6-tertiary butyl) meta cresol (Lowinox 445S6) and amine derivatives IPPD, CPPD, DPPD.

The process of submerging glove formers (molds) into tanks containing a compound or solution. The hand-shaped formers are coated with coagulant (e.g., calcium nitrate) and dipped into the latex to coat them with a thin film of latex. The coagulant converts the liquid latex film into a wet-gel on the former. Subsequent passage through a warm oven completes the coagulation process.

The maximum radiation dose that can be delivered to a product before unacceptable damage occurs.

Contact dermatitis usually occurs one to two days after contact with the offending product. This delayed-type is hypersensitive reaction is typically due to excess residual chemicals utilized as accelerators and antioxidants in the manufacturing process.

Products or a company placed on different levels of "hold" or denial from entering the United States until approved through the FDA.

Labeling requirements for medical devices have been established in the Food, Drug, and Cosmetic Act, 21 U.S.C. Title 21 and in the regulations promulgated under the act in the Code of Federal Regulations. General labeling requirements can be found in Part 801.

Three levels are recognized: High Level Disinfectants are chemical germicides that are registered as "sterilants" with the U.S. EPA and may be used for either sterilization or high level disinfectants of medical devices. Intermediate Level Disinfectants are chemical germicides that are EPA registered to inactivate M Tuberculossis var. bovis. Low Level Disinfectants are chemical germicides that are EPA registered as a hospital disinfectant but not a sterilant or tuberculocidal product. Delivery methods include aerosols, spray pumps, concentrates and foam.

Intended and designed for single-use only.

The most common form of perceived allergy; but, in fact, it is not an allergy. Cause: Frequent hand washing, strong surgical scrubbing, soaps, detergents, glove powder, and occlusion caused by gloves.

Hypersensitive Protein contact dermatitis is caused by special human antibodies. Instant allergies are presented usually within 30 minutes after allergen contact. Cause for type I allergies are the proteins contained in latex.

To remove; to dress out

A set of procedures performed to make sure the dose is still correct. The population and sterilization resistance of microorganisms vary with environmental conditions such as temperature and moisture. Thus, verification of the appropriateness of the sterilizing dose is performed quarterly as a dose audit.

The minimal radiation dose required to sterilize the product to the desired sterilization assurance level (SAL).

To put on; to dress in.

An enzyme that breaks down DNA. If it is present on standard gloves, additional processing is required for its removal. DNAse should be considered when running laboratory DNA isolation, purification and characterization studies.

Method 1, "Dose Setting using Bioburden Information." Determine the number of organisms on the packaged, pre-sterilized gloves. This is followed by irradiation with a dose taken from a table in the AAMI manual calculated to kill 90% of that number of microorganisms. If this sub-lethal dose actually kills at least 90% of the micro-organisms, the standard radiation dose is verified as adequate.

Because glove powder represents a potential hazard to the user and patient (particularly in association with natural rubber latex proteins) the FDA recommends the following statement appear on glove packaging: "Caution: Users should consider the circumstances of use in deciding whether to remove residual powder on glove after donning. Powder can be removed by wiping gloves thoroughly with a sterile wet sponge, sterile wet towel, or other effective methods."

Hypoallergenic As a term for gloves, the claim hypoallergenic was developed to describe a reduced potential for developing a dermatological response to chemicals utilized in production of a given product. The 200-person Modified Draize test is used to determine potential irritancy or allergic contact dermatitis (Type IV) to the product. After producing product to meet these requirements, manufacturers were allowed to utilize the term hypoallergenic as an identifier for the product (a claim). However, in recent years individuals have also developed Type I allergic reactions in association with the proteins in gloves. Because the label claim of hypoallergenic was being interpreted to refer to both Type IV (chemicals) and Type I (protein) allergies, rather than just Type IV, this claim was removed from all gloves September 30, 1998.

Dermatitis develops when a substance repeatedly chemically injures, physically abrades or otherwise damages the skin.

Cellular or systemic response to physiological, chemical or biologic injury. Inflammation occurs as a part of irritation, Type I and Type IV reactions. An extremely dynamic pathological process in which the blood vessels dilate, releasing fluids to the local area. Leukocytes, or white blood cells (WBC) enter, releasing destructive enzymes in their attempt to clean the debris of dead cells. These enzymes cause tissue damage, further increasing the inflammation and depleting these cells of their defense weaponry (enzymes). In so doing, they decrease the local area’s resistance to infection. If the body cannot rid itself of the inflammatory agents, a more chronic inflammatory condition sets in. The body tries to wall off the culprits, to protect the rest of the body, by forming granulomas and adhesions. Four fundamental signs of inflammation are: redness, heat, swelling and pain. A fifth, loss of function. is sometimes present.

An inflammatory reaction of tissues to an injury. An irritation is not an allergic response, it possesses no physiological memory of the substance that caused it. Repeated contact or long-term exposure can result in irritant contact dermatitis on the skin or chronic inflammation in a surgical wound, potentially developing into granulomas or adhesions.

L atex E LISA for A ntigenic P roteins. An ELISA utilizing rabbit IgG antibodies made to latex proteins. The advantages include specificity for latex proteins and a heightened sensitivity or detection capability over the Modified Lowry assay for total protein. The disadvantage of this assay is that the latex protein allergens measured are those recognized by rabbit IgG antibodies and may or may not be recognized by human IgE. Therefore, it is basically a total protein essay and is not allergen specific. As of the printing of this document the LEAP Assay is not a valid measurement under ASTM or FDA guidelines.

A washing process commonly used during glove manufacturing to remove or denature natural water-soluble proteins and remove adverse materials such as processing chemical residues. Water, or "wet gel leaching", is the process of immersing the latex-coated formers into a bath or spray of water, to wash out excess additives from previous stages, such as coagulant. Chemical and protein content can be reduced at this stage. The effectiveness of the process is dependent on the temperature of the water, the duration of the process, and the rate of water exchange. "Dry-film" leaching is similar to the wet-film leaching, except it is carried out on the dry/vulcanised latex film. The effectiveness of this process in reducing water extractives is a function of time and temperature. Some manufacturers leach the gloves at this stage for up to 24 hours.

A test method used to determine the concentration of total protein present in a sample. A Modified Lowry assay was developed for use with latex products. In the Modified Lowry assay (ASTM D5712), latex proteins are extracted from products and purified by acid precipitation. This step diminishes the chemicals present in the product that may interfere with the assay. A protein detection agent is then added that increases in color intensity with increasing amounts of protein. Results are expressed as micrograms (_g) of total protein extracted or microgram per gram (_g/g) of sample. The greater the number, the greater the amount of protein present. This is the only method currently accepted by the government for the measure of protein level in latex products. The amount of protein on a glove generally correlates with the amount of allergen (the proteins people react to). However, not all latex proteins are allergens.

These antibodies in genetically predisposed (atopic) individuals will recognize and react with the same or similar proteins (cross-reactive proteins) in subsequent exposures. Repeated exposure to the protein allergens (or look-a-like cross-reactive allergens) through dermal, mucosal, pulmonary or invasive routes, asymptomatically (without experiencing symptoms) increases the number of sensitized mast and basophil cells until a critical threshold is reached. Once this critical threshold is attained, symptoms may occur including urticaria, rhinitis, dyspnea, abdominal cramps, headache, hypotension, tachycardia and rarely anaphylactic shock.

Rating levels developed by the American National Standards Institute (ANSI) to comply with OSHA madates for industrial gloves . Within the ANSI/ISEA 105-2000 guidelines, glove performance and pass/fail criteria are included for the following hazardous exposures: cut, puncture and abrasion resistance; protection from cold; chemical permeation and degradation; detection of holes; and heat and flame resistance. The standard also includes reference information on special considerations such as biological protection, electrical protection and radiation hazards.

Bacteria appearing elongated in shape.

A radioimmunoassay designed to detect allergens responsible for tissue hypersensitivity. The protein allergen is bound to a surface such as plastic plates or spheres. The patient’s serum is added. If the serum contains antibody to the allergen, the antibodies will attach to the allergen. The level of attachment is measured and the amount quantified. The test may be designed the other way, where the IgE antibodies are placed on the surface. Then an extract of the product, such as a glove, is added to the test to determine if allergens are present.

The area affected usually increases with repeated exposure. Examples include Type IV allergies to: poison oak, nickel, soaps and fragrances.

The lymphocyte responsible for cell-mediated immunity. When sensitized, T-lymphocytes have a receptor that recognizes a specific chemical antigen (chemical sensitizer). On subsequent exposure to that chemical, the sensitized T-cell releases lymphokines, which attract macrophages, neutrophils and other white blood cells to the reaction site. Inflammation ensues and can become chronic. This condition, Type IV hypersensitivity, is also know as allergic contact dermatitis, delayed hypersensitivity or chemical allergy.
