Side effects of antimotion sickness drugs.

The possible influence on operational proficiency of the side effects of the anti-motion sickness drugs was investigated using a computerized pursuit meter as the test device. The medications and doses tested were scopolamine (Hyoscine) 0.25 mg and 0.

Amputation risk factors in concomitant superficial femoral artery and vein injuries.

Only a small subset of patients with combined superficial femoral artery and vein injuries results in amputation. The importance of the venous component as a risk factor for amputation is uncertain. Ligation vs.

Pursuit Meter II, a computer-based device for testing pursuit-tracking performance.

The Pursuit Meter II, a microcomputer-based device developed for the quantitative determination of human pursuit-tracking performance, is described. Computer-generated moving patterns are displayed on a high resolution color video monitor. For the subject the task is to attempt to superimpose a red line presented on the screen, the vertical location of which he controls with a steering device, over a blue line the computer generates as the problem.

The clinical significance of volume-adjusted maximal mid-expiratory flow (Iso-volume FEF25-75%) in assessing airway responsiveness to inhaled bronchodilator in asthmatics.

The clinical significance of Iso-volume FEF25-75% in assessing airway responsiveness to an inhaled bronchodilator was evaluated in 167 asthmatics who presented with variable degrees of airway dysfunction. Iso-volume FEF25-75% identified responsiveness in one patient (5%) out of 20 of the most dysfunctional asthmatics, in three (20%) out of 15 of the least dysfunctional asthmatics and over-all in four (8%) out of 47 asthmatics not showing significant responsiveness via the FEV1. Over-all, FEV1 identified significant responsiveness in more patients (68.

Volume-adjusted maximal mid-expiratory flow (Iso-volume FEF25-75%): definition of "Significant" responsiveness in healthy, normal subjects.

Iso-volume FEF25-75% was evaluated in 30 non-smoking, healthy subjects (16-58 years) to define the percentage change over baseline required for responsiveness to inhaled bronchodilators using this measurement to be significant. The mean percentage change from baseline for Iso-volume FEF25-75% was 15.3% +/- 17.

A classification system for asthmatic patients: clinical-physiological correlation.

A classification system for asthmatics based on simple, readily available clinical tools is defined and evaluated. Asthmatics so classified differed significantly in terms of their degree of dysfunction at the time of presentation. Comments regarding the relative importance and proper perspective of pulsus paradoxus and retraction of the sternocleidomastoid muscle in each classification of asthmatics is made.

Comprehensive hearing aid program within an ear, nose, and throat office.

Hearing aid dispensing within an otolaryngological/audiological clinic is a well accepted fact, and offers total hearing care in a professional setting. The effectiveness of such a program as to wearing habits and acceptance of services rendered, to my knowledge, has not been studied. This paper discussed data obtained from a questionnaire sent out to 1100 hearing aid patients.
