Esterified estrogens and conjugated equine estrogens and the risk of venous thrombosis. Clinical trial evidence indicates that estrogen therapy with or without progestins increases venous thrombotic risk. The findings from these trials, which used oral conjugated equine estrogens, may not be generalizable to other estrogen compounds. Objective: To compare risk of venous thrombosis among esterified estrogen users, conjugated equine estrogen users, and nonusers. Methods: This population-based, case-control study was conducted at a large health maintenance organization in Washington State. Cases were perimenopausal and postmenopausal women aged 30 to 89 years who sustained a first v...

Methods: Official races at US professional racing facilities (n = 114) from January 1, 1993, through December 31, 1996. Methods: A licensed jockey population of approximately 2700 pe...
Equestrian injuries. Results of a prospective study. In a prospective study involving 110 injured equestrians, there were no noteworthy correlations between age, sex, or experience of the amateur riders and injury occurrence. Tack failure caused several injuries. Among fox hunters the incidence was related only to frequency of hunts. The most common severe injury was to the head, associated with lack of headgear. Fewer than 20% of the 110 riders used a protective helmet. There were four renal contusions and one bladder laceration. The most frequent injuries were fractures of the upper extremities. Wearing a good-quality protective helmet and che...
