The effects of a hockey-specific training program on performance of Bantam players.

Few studies have attempted to identify the effects of training on performance measures related to ice hockey. The present study was designed to examine the effects of a 7-week hockey-specific training program on the on- and off-ice test performance scores of 14- and 15-year-old (Bantam) hockey players. Pre- and post-training tests of percent fat (ultrasound), center of gravity location, 40-yard dash, vertical jump, and on-ice tests of top speed, acceleration, and concerning ability were completed on 28 male subjects (16 in a training group, 12 in a control group of summer league participants). The training group showed significant improvements (p less than .01) in percent fat, top speed, acceleration, and cornering test performance whereas only percent fat was significantly improved for the control group. The results suggest that performance on tests related to ice hockey can be improved by training specifically for hockey but that performance is not affected by summer league play alone.

Botulism from chopped garlic: delayed recognition of a major outbreak.

Diagnosis of botulism in two teenaged sisters in Montreal led to the identification of 36 previously unrecognized cases of type B botulism in persons who had eaten at a restaurant in Vancouver, British Columbia, during the preceding 6 weeks. A case-control study implicated a new vehicle for botulism, commercial chopped garlic in soybean oil (P less than 10(-4)). Relatively mild and slowly progressive illness, dispersion of patients over at least eight provinces and states in three countries, and a previously unsuspected vehicle had contributed to prolonged misdiagnoses, including myasthenia gravis (six patients), psychiatric disorders (four), stroke (three), and others. Ethnic background influenced severity of illness: 60% of Chinese patients but only 4% of others needed mechanical ventilation (P less than 10(-3]. Trypsinization of serum was needed to show toxemia in one patient. Electromyography results with high-frequency repetitive stimulation corroborated the diagnosis of botulism up to 2 months after onset. Although botulism is a life-threatening disease, misdiagnosis may be common and large outbreaks can escape recognition completely.

Vancouver's needle exchange program.

To stem the spread of HIV among intravenous drug users, and between them and their sexual partners and offspring, Vancouver initiated a multifaceted "ways and means" needle exchange program in March of 1989. As of the end of October, over 2,600 users have registered. The needle exchange rate has increased steadily, reaching a peak of 98% in November. Increases have also been noted in the number of regular users, and requests for referral to addition, medical, social and HIV-related services. Outreach services, especially using a van, have expanded program availability. Success in terms of clientele response is accredited primarily to the nonjudgemental, nonintrusive approach. The main problems have been the lack of addiction treatment services, financial and personnel constraints created by the large enrollment, and difficulties with Federal/Provincial funding. Funding for evaluation has been requested.
