An outbreak of cryptosporidiosis associated with a resort swimming pool.
(25/27)
An outbreak of cyptosporidiosis occurred in late April 1993 among resort hotel guests which was temporally associated with, but geographically distant from, a massive waterborne outbreak of cryptosporidiosis in Milwaukee, Wisconsin, that occurred in late March and early April of 1993. A case-control study was performed among groups with members who reported illness and among a systemic sample of groups who stayed at the resort hotel during the risk period. Of 120 persons interviewed, 51 (43%) met the case definition. Swimming in the resort hotel's pool was significantly associated with case status (OR = 9.8; 95% Cl 3.4, 29.7), as was consumption of ice from the hotel's ice machines (OR = 2.3; 95% Cl 1.01, 5.2). When analysis was restricted only to laboratory-confirmed cases and controls, swimming pool use was the only risk factor significantly associated with illness (OR = 13.0; 95% Cl 2.6, 88.7). Following waterborne outbreaks of cryptosporidiosis associated with water supplies, swimming pools should be considered as possible ongoing sources for transmission regionally. (+info)
Shigella sonnei outbreak associated with contaminated drinking water--Island Park, Idaho, August 1995.
(26/27)
On August 20, 1995, the District 7 Health Department requested the Idaho Department of Health to assist in investigating reports of diarrheal illness among visitors to a resort in Island Park in eastern Idaho; Shigella sonnei had been isolated from stool cultures of some cases. This report summarizes the findings of the investigation, which implicated contaminated drinking water as the cause of the outbreak. (+info)
Prolonged effects of 3 week therapy in a spa resort on lumbar spine, knee and hip osteoarthritis: follow-up after 6 months. A randomized controlled trial.
(27/27)
Spa therapy is frequently used in daily rheumatological practice, but its benefit remains to be evaluated. A prospective randomized controlled study was conducted in 1993 in patients with osteoarthritis of the hip, knee or lumbar spine. Treatment was either spa therapy at Vichy (France) of 3 weeks duration (spa group) or usual therapy (control group). Assessment criteria were pain (visual analogue scale), functional impairment (Lequesne's index for hip or knee disease, Main and Waddell's for lumbar spinal diseases), quality of life index [revised Arthritis Impact Measurement Scale (AIMS2)], and analgesic and/or non-steroidal anti-inflammatory drug (NSAID) consumption. Patients were included by randomization into one of the two arms (spa or control) and assessment criteria were collected before spa therapy or the control period, and 3 and 24 weeks thereafter. A total of 188 patients (lumbar spine 95, knee 64, hip 29) were included in the study (spa group 91, control group 97). Changes in the assessment criteria after a 6 month follow-up period showed improvement in terms of pain, functional impairment and quality of life, with a reduced intake of symptomatic drugs (NSAID and analgesic drugs) in the spa group. This study suggests that spa therapy of 3 weeks duration has a prolonged, beneficial, symptomatic effect in osteoarthritis. (+info)
