Relaxation therapy is an effective means of reducing the stress response in some individuals. The degree of anxiety that an individual experiences in response to stress is related to cer- tain predisposing factors, such as characteristics of temperament with which he or she was born, past experiences resulting in learned patterns of responding, and existing conditions, such as health status, coping strategies, and adequate support systems. Deep relaxation can counteract the physiological and be- havioral manifestations of stress. Various methods of relaxation include the following: Deep-Breathing Exercises: Tension is released when the lungs are allowed to breathe in as much oxygen as pos- sible. Deep-breathing exercises involve inhaling slowly and deeply through the nose, holding the breath for a few seconds, then exhaling slowly through the mouth, pursing the lips as if trying to whistle. Progressive Relaxation: This method of deep-muscle re- laxation is based on the premise that the body responds to anxiety-provoking thoughts and events with muscle tension. Each muscle group is tensed for 5 to 7 seconds and then relaxed for 20 to 30 seconds, during which time the individual concentrates on the difference in sensa- tions between the two conditions. A modified version of this technique (called passive progressive relaxation) involves re- laxation of the muscles by concentrating on the feeling of relaxation within the muscle, rather than the actual tens- ing and relaxing of the muscle. It brings on a special state of consciousness as attention is concentrated solely on one thought or object. During meditation, as the individual becomes totally pre- occupied with the selected focus, the respiration rate, heart rate, and blood pressure decrease. The frame of reference is very personal, based on what each individual considers to be a relaxing environment. The relaxing sce- nario is most useful when taped and played back at a time when the individual wishes to achieve relaxation. Biofeedback: Biofeedback is the use of instrumentation to become aware of processes in the body that usually go un- noticed and to help bring them under voluntary control. Biological conditions, such as muscle tension, skin surface temperature, blood pressure, and heart rate, are monitored by the biofeedback equipment. With special training, the individual learns to use relaxation and voluntary control to modify the biological condition, in turn indicating a modification of the autonomic function it represents. Bio- feedback is often used together with other relaxation tech- niques such as deep breathing, progressive relaxation, and mental imagery. Assertive behavior increases self-esteem and the ability to develop satisfying interpersonal relationships. This is ac- complished through honesty, directness, appropriateness, and respecting one’s own rights, as well as the rights of others. Individuals develop patterns of responding in various ways, such as role modeling, by receiving positive or negative rein- forcement, or by conscious choice. These patterns can take the form of nonassertiveness, assertiveness, aggressiveness, or passive-aggressiveness. Nonassertive individuals seek to please others at the expense of denying their own basic human rights. Assertive individuals stand up for their own rights while protecting the rights of oth- ers. Those who respond aggressively defend their own rights by violating the basic rights of others. Individuals who respond in a passive-aggressive manner defend their own rights by expressing resistance to social and occupational demands. Some important behavioral considerations of assertive be- havior include eye contact, body posture, personal distance, physical contact, gestures, facial expression, voice, fluency, tim- ing, listening, thoughts, and content. Example: “I don’t want to go out with you tonight,” instead of “I can’t go out with you tonight. Example: Telephone salesperson: “I want to help you save money by changing long-distance services. Example: Male board member: “You made a real fool of yourself at the board meeting last night.

Concurring with the critic’s argu- ment without becoming defensive and without agreeing to change. Putting off further discussion with an angry in- dividual until he or she is calmer. In cognitive therapy, the in- dividual is taught to control thought distortions that are consid- ered to be a factor in the development and maintenance of mood disorders. In the cognitive model, depression is characterized by a triad of negative distortions related to expectations of the environment, self, and future. The environment and activities within it are viewed as unsatisfying, the self is unrealistically devalued, and the future is perceived as hopeless.

These retrospective risk ratios for benefit and harm can be benefit–risk assessments must be derived from calculated.

Their assessment of this ‘ratio’ tiveness of dantrolene in malignant hyperthermia in everyday practice, using approved drugs, is (Strazis and Fox, 1993). In practice, clinicians make prescribing decisions based upon (a) a subset of the published information that might be available about the drug (labeling, drug repre- 9. Further- Special populations may require small-scale studies more, we all operate algorithms taught us by others to supplement a traditional two-study, large-scale whom we respect, and thus we use others’ experi- registration development scheme. Similarly, if (in ence with drugs and patients, quite apart from the the United States) the proposed indication has an often hard-learned lessons from our own therapeu- approved Orphan Drug designation, then small- tic adventures (pace ‘evidence-based medicine’).

However, unlike in general resource utilization becomes exponentially more medical practice, these extrapolations are often important than before. The incorporation of phar- not from clinical experience, but rather from phar- macoeconomic and humanistic outcomes along- macokinetic models or animal data, or at best from side the primary registration end points is patients who are clearly dissimilar from that pro- becoming essential, and preparatory work is best posed in the new trial. Certainly, the mathematical approach cannot There are highly mathematical approaches to be expected on the part of the patient nor will it benefit–risk assessment.
