Teaching with symbols tangentially related to topic: using a linked multimedia approach to enhance learning.

40 undergraduate students, none of whom were history or literature majors, attended a lecture on Medieval literature. For half the students the lecture was supplemented by two sets of slides. One set summarized course content while the second set contained slides of paintings or other forms of visual art which were only tangentially related to the topic.

Acute ketamine intoxication treated by haloperidol: a preliminary study.

In an open, double-blind study of phencyclidine intoxication, 21 white male subjects were later found to have instead ingested ketamine. These subjects were divided into two cohorts, one treated with 5 mg intramuscular haloperidol and the second with an active placebo. Assessment with the Brief Psychiatric Rating Scale revealed significant reduction in symptoms with haloperidol.

Measurement of nonverbal receptive abilities in medical students.

Physicians have been reported to have difficulty in communicating with their patients. An element of this communication gap is proposed be related to the educational curriculum and the selection process of medical schools, in particular, with the emphasis on scientific methodology reducing exposure to humanistic values. This hypothesis was tested by measuring nonverbal receptive abilities in two groups.

Use of tangential visual symbols to increase the long-term learning process: applications of linkage in teaching pharmacological principles of addiction.

Medieval and Renaissance teaching techniques using linkage between course content and tangentially related visual symbols were applied to the teaching of the pharmacological principles of addiction. Forty medical students randomly divided into two blinded groups viewed a lecture. One lecture was supplemented by symbolic slides, and the second was not.

An approach to drug abuse, intoxication and withdrawal.

The symptomatic effects of drug abuse are a result of alterations in the functioning of the following neurotransmitters or their receptors: acetylcholine, dopamine, gamma-aminobutyric acid, norepinephrine, opioids and serotonin. Anticholinergic drugs antagonize acetylcholine receptors. Dissociative drugs affect all transmitter sites.

Magnesium oxide augmentation of verapamil maintenance therapy in mania.

The authors compared the antimanic effects of a verapamil-magnesium oxide (V-M) combination with a verapamil-placebo combination (V-P) in patients pretreated with verapamil. BPRS scores and serum magnesium levels were compared. The V-M combination was found to be significantly more effective than V-P in reducing manic symptoms (P=0.

Perception of nonverbal facial cues in chronic phencyclidine abusers.

The ability to interpret nonverbal facial cues was tested in 10 young white male chronic phencyclidine (PCP) abusers. When their responses were compared with those of age-matched controls, abusers were significantly more accurate in interpreting the facial cues of videotaped medical interns. Phencyclidine abusers tend to form a socially maladroit and downwardly mobile group.

Visual symbolization as a learning tool: teaching pharmacology to international audiences.

Medieval and Renaissance teaching techniques used linkage between course content and tangentially related visual symbols to reinforce lectures. This technique was adopted in teaching pharmacologic principles of addiction to international audiences. It produced significant results with non-English-speaking audiences using concurrent or consecutive translation.

Alexithymia, affective disorders and substance abuse: possible cross-relationships.

Alexithymia is a syndrome manifesting affective, cognitive, and perceptual social defects, which include diminished affective-interpretive abilities. These abilities have been observed to be decreased in opiate abuse, major depression, and premenstrual depressive disorder, but increased in cocaine abuse and manic states. Conditions associated with decreased affective-interpretive abilities are also associated with decreased central catecholamine levels.

Treatment of Khat Addiction with Bromocriptine Mesylate: A Case Report and Review of Cocaine- and Amphetamine-Like Effects.

A patient addicted to khat was successfully treated as an outpatient. He was detoxified with bromocriptine mesylate 1.25 mg.

Tangential symbols: using visual symbolization to teach pharmacological principles of drug addiction to international audiences.

Visual art was used to teach the biopsychiatric model of addiction to audiences in the Caribbean, Europe and Mideast. Art slides were tangentially linked to slides of pharmacological data. Stylistically dense art was processed by the intuitive right brain while spare notational pharmacological data was processed by the intellectual (rationalistic) left brain.
