Trichloroethylene (TCE) has been identified as an environmental contaminant in groundwater. Trichloroacetic acid (TCA), dichloroacetic acid (DCA), chloral hydrate (CH), trichloroethanol (TCOH), and trichloroethanol glucuronide (TCOG) have been identified as metabolites of TCE. Studies have shown that TCA and DCA are toxicologically significant metabolites that can induce liver tumors in B6C3F1 ...

OBJECTIVE Trichloroacetic acid (TCAA), or trichloroethanoic acid, is a chemical analogue of acetic acid where three methyl group hydrogen atoms are replaced by chlorine. TCAAs are also abbreviated and referred to as TCAs, causing confusion with the psychiatric antidepressant drug class, especially among patients. TCAAs exist in dermatological treatments such as chemical peels or wart chemoablat...

When trichloroacetic acid (TCA) and trichloroethanol (TCE) in the urine of human subjects, rabbits, rats, and guinea-pigs were determined by Seto and Schultze's (I956) method, the recovery of TCE, added to urine, varied widely from 8i 3% in guinea-pig urine to i6-2% in rat urine. To obtain the maximum recovery of added TCE, Seto and Schultze's method was further modified to give satisfactory re...

Apart from the famously known Koebner's phenomenon in vitiligo patients (development of isomorphic lesions at traumatized uninvolved skin of patients with cutaneous diseases), [2] it is widely known that there is wound-associated pigmentation in normal individuals. The latter could be explained by two major processes; the first is incontinentia pigmenti, which occurs after destroying the basal ...

Trichloroacetic acid (TCA), in former times used as a herbicide in agriculture, is now ubiquitous and almost evenly distributed in precipitations of the Northern and Southern Hemisphere, despite larger emissions of the possible precursors tetrachloroethene and 1,1,1-trichloroethane in the Northern Hemisphere. The permanent input of a herbicidal compound into most vulnerable ecosystems might lea...

In an observer blind comparative study, 130 men with penile warts were randomly allocated to treatment with either cryotherapy or trichloroacetic acid (TCAA). There was no significant difference in response to treatment, side effects, or recurrence rates between the two treatments. Warts resolved in 81% of patients treated with TCAA compared with 88% of those treated with cryotherapy. Early rec...

BACKGROUND Ingrown nails are a very common problem. There are different stages of disease and diverse therapeutic options. Phenol and sodium hydroxide are commonly used agents for chemical matricectomy but both frequently entail excessive healing times. OBJECTIVE This prospective study aimed mainly to evaluate the efficacy of partial nail avulsion and selective chemical cauterization of the m...

Trichloroacetic acid (TCA) has been implicated as an airborne pollutant responsible for adverse effects on forest health. There is considerable debate as to whether TCA observed in trees and forest soils is derived from atmospheric deposition or from in situ production. This experiment reports the results from treating 4-year-old Sitka spruce (Picea sitchensis (Bong.) Carr) plants in a greenhou...
