The effect of the mandatory use of face masks on facial lacerations and head and neck injuries in ice hockey. A prospective study.

A 4-year prospective review of lost-time injuries and facial lacerations was performed for a National Collegiate Athletic Association Division I, intercollegiate ice hockey team. The total injury exposure time consisted of 798.5 practice hours and 163 games. There were 16 facial lacerations, with an incidence of 14.9 per 1000 player-game hours and 0.1 per 1000 player-practice hours; both incidences were found to be less than in previous comparable studies where the use of face masks was not mandatory. In addition, there were eight lost-time head and neck injuries that accounted for 6.3% of all lost-time injuries. We found that the mandatory use of face masks in intercollegiate ice hockey results in a reduction in facial lacerations and no increase in overall head and neck injuries.

Effects of air injection into the corneal stroma of man: an in vitro study.

BACKGROUND: Corneal stromal air injection has been described for assisting the deep dissection of the recipient corneal bed in lamellar grafting. The consistent finding of air entering the anterior chamber is considered an undesirable complication of the procedure. The route of air entry into the anterior chamber has not been investigated previously. METHODS: The route of air passage through the cornea was studied in 10 human cadaver eyes by direct viewing of the inner corneal surface with an operating microscope and by electron microscopy. RESULTS: Air entered the anterior chamber peripheral to Descemet's membrane in every case in the absence of pre-existing corneal pathology. The air expansion of the cornea occurred only along planes occupied by keratocytes and their cell processes and this expansion caused disruption of the keratocytes. CONCLUSIONS: Air injection into the cornea caused bubbles to enter the anterior chamber peripheral to Schwalbe's line, through the trabecular meshwork. The air produced cleavage of the collagen lamellae along those planes occupied by keratocytes and their cell processes since this provides a path of least resistance. Disruption of the keratocytes is a direct mechanical effect. Descemet's membrane and Bowman's layer act as effective barriers to air passage in the normal cornea.

The family physician and ethics at the bedside.

BACKGROUND: Clinical ethics and ethics committees are a real phenomenon in medicine and play an important role in improving patient care by enhancing the decision-making process between patients and their physicians and thus strengthening this special bond. This article reviews the evolving qualifications of the clinical ethics consultant and compares them with the traditional knowledge, skills, attitudes, and values of the family physician. METHODS: Maternal for this comparison was gathered from a review of the pertinent literature of the past 10 years on the development of clinical ethics and the addition of ethics to the medical curriculum and from personal observations and literature commentary on family practice as a distinct entity. RESULTS AND CONCLUSIONS: Family physicians are uniquely qualified to serve as ethics consultants, particularly with additional training in moral philosophy and health care law. It is hoped that family physicians will become increasingly involved in this growing field to serve as future teachers, researchers, institutional leaders, and policy makers in clinical ethics. More importantly, faculty role models are needed to train family practice residents in ethical decision making at the bedsides of their patients.
