Toxic conjunctivitis

Anaphylactoid conjunctivitis Allergic contact (dermato-) conjunctivitis Cicatrizing allergic conjunctivitis Nonspecific (papillary) irritative or toxic conjunctivitis Follicular irritative or toxic conjunctivitis Cicatrizing and keratinizing irritative or toxic conjunctivitis (including pseudotrachoma) Cumulative deposition Microbial imbalance... 

Conjunctivitis caused by toxic agents can occur as either a primary or a secondary finding. Toxicity most commonly results from exposure to medications, contact lens care products, or cosmetics. However, any agent can cause a toxic response. Toxic conjunctivitis may have a wide variety of presentations. When superimposed over infection or allergic reaction, toxicity to a medication may complicate the diagnosis. 

Elimination of the toxin is the only totally effective means by which to eliminate toxic conjunctivitis. Often, products that contain different preservatives from those contained in the offending product can be substituted, typically resulting in complete cure. Once the toxin is identified, patients should be advised to avoid agents to which they are sensitive. Dilution of environmental toxins may reduce symptoms however, this is only palliative. 

Prepares labels for containers, User may copy information from MSDSs or other text flics. May be used in conjunction with TOXIC ALERT. 

VDI Part 1 models the dispersion of vapor plumes with output consisting of vapor ctiriccntration as a function of time and downwind distance and denser-than-air vapor releases. VDI Part 2 determines the downwind distance to the lower flammable limit of a combustible vapor. Part 2 may also be used in conjunction with Part 1 to model a toxic gas emission. 

Bums and Hazzan demonstrated tlie use of event tree and fault tree analysis in tlie study of a potential accident sequence leading to a toxic vapor release at an industrial chemical process plant. The initiator of tlie accident sequence studied is event P, the failure of a plant programmable automatic controller. Tliis event, in conjunction willi the success or failure of a process water system (a glycol cooling system) mid an operator-manual shutdown of tlie distillation system produced minor, moderate, or major release of toxic material as indicated in Fig. 21.4.1. The symbols W, G, O represent tlie events listed ... 

Safety pharmacology studies may also be conducted in conjunction with the toxicity studies. These focus on identifying secondary pharmaceutical side effects that may occur, when the drug is administered in the therapeutic range. Emphasis is placed on identifying effects on vital systems, particularly the central nervous, cardiovascular and respiratory systems.
