Definition: This block contains a wide variety of disorders that differ in severity and clinical form but that are all attributable to the use of one or more psychoactive substances, which may or may not have been medically prescribed. The third character of the code identifies the substance involved, and the fourth character specifies the clinical state. The codes should be used, as required, for each substance specified, but it should be noted that not all fourth character codes are applicable to all substances. Identification of the psychoactive substance should be based on as many sources of information as possible. These include sel ...[+++]f-report data, analysis of blood and other body fluids, characteristic physical and psychological symptoms, clinical signs and behaviour, and other evidence such as a drug being in the patient's possession or reports from informed third parties.

The main diagnosis should be classified, whenever possible, according to the substance or class of substances that has caused or contributed most to the presenting clinical syndrome. Other diagnoses should be coded when other psychoactive substances have been taken in intoxicating amounts (common fourth character .0) or to the extent of causing harm (common fourth character .1), dependence (common fourth character .2) or other disorders (common fourth character .3-.9).

There may be differential loss between the sensory modalities which cannot be due to a neurological lesion. Sensory loss may be accompanied by complaints of paraesthesia. Loss of vision and hearing are rarely total in dissociative disorders. | Psychogenic deafness

Mr. Clifford Lincoln: I'm just trying to put a timeline on it because I think it's completely unfair to leave it floating, in the case of certain institutions, and saddle members of the public with a different type of onus that is completely.If any institution is in the position to be able to react to these issues quickly, it is those that have the resources, power and wherewithal to do it.

The Pacific Salmon Commission conducts test fisheries and biological sampling, collates catch information, reports on the progress of escapement into the Fraser River based on Mission hydro-acoustic data, and makes recommendations to the Fraser River panel regarding adoption of run size timing and diversion rates by stock group as well as providing total allowable catch figures on a weekly basis.

I listened to the hon. member for Renfrew-Nipissing-Pembroke and I totally disagree with the chronology that he just described.
