Symptom Patterns

This factor refers to the spatial organization of the information displays. In general, instruments displaying process parameters that are functionally related should also be physically close. In this way, it is likely that a given fault will lead to a symptom pattern that is easier to interpret than a random distribution of information. Although violation of this principle may not induce errors in a direct manner, it may hinder human performance. The following example illustrates this point. 

The use of biolc c indicators as an early detection system for severe air pollution episodes or for chronic air pollution problems is of interest to many urban and industrial control officials. Plants served as air pollution detection sterns long before pollution was acknowledged a problem by industry or government. Higher plants serve as useful detection tools, because they develop characteristic symptoms from acute exposure, even though the symptoms are not necessarily specific to cause. Cause and effect can be reliably ascertained, when an air pollution source is identified and symptom patterns are identified within given sensitive species. 

The options depend upon the symptom patterns but all patients benefit from clear explanation of the lack of significant organic disease, and that simple dietary and other manoeuvres as well as reduction of stress may help. Treatment considerations are hindered by the disparity between the extensive analyses performed on modern possible treatments and the more skeletal information available about older ones. 

Symptom patterns those with alternating constipation and diarrhoea and predominant constipation may benefit from high fibre diets (although excess fibre may bloat). Those with predominant diarrhoea may require simple peripheral opiate agonists (loperamide), but may also be helped by raised fibre intake. Pain may respond in part to explanation that it does not indicate serious illness and in part to spasmolytic therapy with anticholinergic agents which... 

Hyperactivity in children was first described clinically in 1902 and the first report of treatment with a stimulant was in 1937 ( 44). Hyperactivity was the initiai focus but recentiy the importance of attentionai probiems and impuisivity has aiso been recognized, as reflected in Diagnostic and Staiisticai Manuai, 4th ed (DSM-IV) criteria (45). These criteria require an enduring symptom pattern that has resulted in functional impairment.

If symptoms of despair and hopelessness are sufficiently severe, an additional diagnosis of major depressive disorder may be warranted. If the symptom pattern does not meet criteria for ASD, however, a diagnosis of adjustment disorder should be considered in lieu of PTSD. 

Beginning with Kraepelin s (1921) systematic classification of dysphoric mania, considerable attention has been paid to mixed states of bipolar disorder. Kraepelin s model was based on variable symptom patterns expressed in three areas, mood, thought, and motor activity. Once considered to be uncommon, current estimates suggest that the prevalence rate for dysphoric, or mixed mania, is approximately 30 percent (McElroy et al. 1992). Debate continues regarding the status of mixed mania as a distinct affective state versus a form, or stage, of typical mania. However, there is convincing evidence to support the opinion that mixed episodes can be more severe, chronic, and difficult to treat than pure manic or depressive episodes (Clothier,... 

The results showed that post-conflict syndromes which show considerable similarities to Gulf War illness have been reported after all of the major conflicts involving the British Armed Forces. The names have changed but there has also been some shift in the symptom patterns recorded, from the debility/weakness picture of Victorian neurasthenia to the more neuropsychiatric (including cognitive and depressive symptoms) of modern times. 

The age of onset and the symptom pattern appear to be related to the level of sensitivity. The onset is often acute and dramatic, and may mimic acute gastroenteritis in very early infancy, with vomiting and/or severe diarrhea which may be associated with dehydration, collapse, or shock. After the first few months of age, the onset of gastrointestinal...
