Is panic disorder associated with coronary artery disease? A critical review of the literature.

Objective: To critically review existing literature examining the relationship between panic disorder (PD) and coronary artery disease (CAD). We specifically sought answers to the following questions: (1) What is the prevalence of PD in CAD patients? (2) What is the directionality of the relationship between PD and CAD? (3) What mechanisms may mediate the link between PD and CAD?

Methods: Medline and Psychlit searches were conducted using the following search titles: "panic disorder and coronary artery disease", "panic disorder and coronary heart disease", and "panic disorder and cardiovascular disease" for the years 1980-1998. The above search was also repeated replacing "panic disorder" with "panic attacks" for the same period.

[Deficit in suppression of interference in visual information processing by schizophrenic subjects].

Although many studies have indicated information processing deficits in schizophrenic patients, the precise nature and underlying causes of these deficits remain largely uncertain. One prominent hypothesis is that these patients show insufficient attentional inhibition. This deficit to inhibition has been linked to certain cognitive disorders in schizophrenic patients, including attention deficits, as well as to some clinical symptoms, especially those involving delusional thought, hallucinations,and poor contact with reality.

The impact of depression on the course and outcome of coronary artery disease: review for cardiologists.

Epidemiological research over the past decade indicates that major depression and depressive symptomatology are common among patients with coronary artery disease (CAD) and postmyocardial infarction. Major depression is a serious, debilitating comorbid disorder that can significantly increase risk for and complicate recovery from cardiac events (eg, myocardial infarction). Unfortunately, major depression is rarely detected or treated in the cardiology setting.

Three-dimensional MRI atlas of the human cerebellum in proportional stereotaxic space.

We have prepared an atlas of the human cerebellum using high-resolution magnetic resonance-derived images warped into the proportional stereotaxic space of Talairach and Tournoux. Software that permits simultaneous visualization of the three cardinal planes facilitated the identification of the cerebellar fissures and lobules. A revised version of the Larsell nomenclature facilitated a simple description of the cerebellum.

Hostility, sodium consumption, and cardiovascular response to interpersonal stress.

Objective: Previous studies have reported poorer health behaviors in high vs. low hostile subjects. The role of stress in these observed differences has not been explored although interpersonal stress does increase cardiovascular response in high hostiles.

Comparative pharmacokinetics of morning and evening doses of once-a-day theophylline capsules.

The objective of this study was to determine if the theophylline diurnal variation that has been observed primarily between morning and evening doses of twice-a-day products could be overcome by a once-a-day formulation. Eighteen healthy, nonsmoking, adult male subjects were given 900-mg theophylline doses as three 300-mg once-a-day theophylline capsules in the morning or evening for 5 days in a single-blind fashion. Matching placebo capsules were administered midway between each dose of active drug.

Inhibition of bacterial growth in vitro following stimulation with high voltage, monophasic, pulsed current.

Low-intensity direct current has been reported to be effective in promoting healing of infected wounds, and these results have been assumed to apply to stimulation of wound tissue with monophasic high voltage pulsed current (HVPC). The purpose of this study was to determine whether HVPC has an inhibitory effect on growth in vitro of three bacterial species--Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa--commonly isolated from open wounds. Following exposure to HVPC, the measured zone of inhibition of bacterial growth was not significantly different between bacterial species.

Toxicity of carbide waste to heterotrophic microorganisms in caves.

The spent carbide from acetylene-generating lamps used by spelunkers has long been assumed to be toxic. Pure cultures ofE. coli, S.
