Book and film The Three Faces of Eve
In 1957, with the publication of the bestselling book The Three Faces of Eve by psychiatrists Corbett H. Thigpen and Hervey M. Cleckley, based on a case study of their patient Chris Costner Sizemore, and the subsequent popular movie of the same name, the American publics interest in multiple personality was revived. More cases of dissociative identity disorder were diagnosed in the following years. The cause of the sudden increase of cases is indefinite, but it may be attributed to the increased awareness, which revealed previously undiagnosed cases or new cases may have been induced by the influence of the media on the behavior of individuals and the judgement of therapists. During the 1970s an initially small number of clinicians campaigned to have it considered a legitimate diagnosis. History in the DSM
The DSM-II used the term hysterical neurosis, dissociative type. It described the possible occurrence of alterations in the patients state of consciousness or identity, and included the symptoms of "amnesia, somnambulism, fugue, and multiple personality". The DSM-III grouped the diagnosis with the other four major dissociative disorders using the term "multiple personality disorder". The DSM-IV made more changes to DID than any other dissociative disorder, and renamed it DID. The name was changed for two reasons: First, the change emphasizes the main problem is not a multitude of personalities, but rather a lack of a single, unified identity and an emphasis on "the identities as centers of information processing".
In the EU classification of dangerous substances it is harmful (Xn) while more toxic substances are classified as toxic (T) or very toxic (T+). The U.S. Environmental Protection Agency generally puts substances which are lethal at more than 30 g to adults in Toxicity Class III.Ethylene glycol has a low vapor pressure; it does not evaporate readily at normal temperatures and therefore high concentrations in air or intoxication are unlikely to occur following inhalational exposures. There may be a slight risk of poisoning where mists or fogs are generated, although this rarely leads to poisoning as ethylene glycol causes irritation and coughing when breathed in, alerting victims to its presence. Ethylene glycol is not well absorbed through skin meaning poisoning following dermal exposure is also uncommon. Diagnosis
As many of the clinical signs and symptoms of ethylene glycol poisoning are nonspecific and occur in many poisonings the diagnosis is often difficult. It is most reliably diagnosed by the measurement of the blood ethylene glycol concentration. Ethylene glycol in biological fluids can be determined by gas chromatography. Many hospital laboratories do not have the ability to perform this blood test and in the absence of this test the diagnosis must be made based on the presentation of the person. In this situation a helpful test to diagnose poisoning is the measurement of the osmolal gap.
