Vitamin A.
Vitamin A refers collectively to a number of compounds, the most biologically active of which is retinol. Named after its earliest discovered function, visual excitation, retinol is also needed for growth and reproduction, and differentiation of epithelial tissue. A closely related form, retinoic acid, has selective biologic activity for normal growth and epithelial differentiation. The term retinoids has been used in recent years to include both natural and synthetic analogs of vitamin A. Carotene and carotenoids refer to vitamin A precursors (pro-vitamins) of vegetable origin. Following a brief historical account of vitamin A and description of dietary information this article focuses on the chemistry and physiology of retinoids. The biological roles of vitamin A compounds are elaborated, as well as the clinical significance of vitamin A deficiency and excess. Discussion of retinoids in therapy includes their use as anti-cancer agents and as therapeutics for dermatological disorders. Finally, a review of analytical techniques for laboratory assessment of vitamin A is presented.
Construction and validation of an equivalency examination for an MLT/MT career mobility curriculum.
A career mobility program in medical technology, recently developed at the University of Illinois Medical Center, Peoria, utilizes equivalency examinations to recognize professional competencies achieved by a medical laboratory technology graduate with an associate degree toward completion of a bacclaureate degree in medical technology. Four criterion-referenced examinations in clinical chemistry, clinical microbiology, hematology, and blood bank-serology were constructed by 30 medical laboratory technician (MLT) and medical technology educators from Illinois community colleges and universities in 1976-1977. A description of the development of these exams, the process of criterion referencing, the administration of the exams for norming, and the utilization of the exams by applicants of the career mobility program is presented.
A career mobility option within a university integrated medical technology program.
Career mobility has become an increasingly important movement influencing the education of allied health professionals in recent years. With the advent of intermediate levels of professionals in several allied health fields, career mobility can facilitate the advancement of careers for many of these health professionals.
Determining continuing education interests of medical technologists: an initial step.
Continuing education is an ever-increasing need for medical technologists who want to maintain and upgrade their professional knowledge and skills. Professional groups strive to develop programs to meet a diversity of needs. Planning groups often encounter difficulty during the program development process as they identify topics and select effective educational strategies for presentation. In order to help identify topics of interest and desirable educational methods for the continuing education of laboratory personnel, a continuing medical technology education interest assessment tool was developed and used by a medical technology continuing education committee. Development and use of this assessment tool and resulting statistical survey results formed the basis for two continuing education courses, both considered highly successful.
